Abstract: The circulating peptide hepcidin is secreted mainly by the liver as an 84 - amino acid precursor that is subsequently processed and secreted as a 25 - amino acid peptide form. It is considered the "master regulator" of iron metabolism.Transferrin receptor is a carrier protein for transferrin. It is needed for the import of iron into the cell and is regulated in response to intracellular iron concentration. It imports iron by internalizing the transferrin - iron complex through receptor - mediated endocytosis. This study addresses the physiological role of hepcidin in vivo and investigates the role of hepcidin as an erythroid regulator, contributing to the modulation of iron absorption by the intestine and iron release by the macrophages in the situation of anemia with normal or increased iron stores. Measuring the transferrin receptor level and it's relation to hepcidin is another part of the data involved in this study.Methods : This study included 64 Iraqi patients, 34 of them have iron deficiency anemia and the other 30 are iron overload patients. They attended the National Center of Hematology and Thalassemia center in Al - Karama Teaching Hospital during the period from October 2014 until April 2015 together with 30 healthy controls. Information regarding age, sex and clinical presentation were recorded. ELISA technique used to measure hepcidin and transferrin receptors level in patients and healthy control groups.Results : ? Mean serum hepcidin level in iron deficiency anemia patients was (205.3ng/ml) while in iron overload patients was (6.7ng/ml).? Mean serum level of transferrin receptors in iron deficiency anemia was (11006.3ng/ml) and in iron overload was (604.5ng/ml).Conclusion : ? The mean level of serum hepcidin in thirty iron deficiency anemia patients is high. Its elevation represented an acute phase response. While in thirty patients with iron overload, hepcidin mean level was low mainly due to stress erythropoiesis.? The current study result addresses the usefulness of soluble transferrin receptor for assessing high iron status in population and how soluble transferrin receptor is useful in the evaluation of anemic patients.

Abstract: تعتبر الاحصائيات الصحية الرصينة ضرورة لاتخاذ القرارات السليمة في كل مستويات النظام الصحي. ولكن في الحقيقة ان نظم المعلومات الصحية في معظم البلدان تعتبر غير كافية لتوفير المعلومات اللا زمة لدعم الادارة الصحية ولهذا فان معظم النظم الحالية تعتبر كعائق اداري | Sound health statistics are essential for health decision - making at all levels of the health system. Unfortunately, health information systems in most countries are inadequate in providing the needed management support and the current systems are therefore widely seen as management obstacles rather than as tools, the current study is an attempt to assess the health information system in Iraq with recognizing the strengths, weaknesses and gaps in addition to assessment of the structure and performance of this system; it also attempts to assess the behavioral, technical and organizational determinants affecting the health information system performance. A cross - sectional study was conducted for the assessment process and the levels of the assessment included the ministry of health (national level), the health directorates (provincial level), the districts related to the health directorates reaching to the health centers level, as well as the hospitals related to the health directorates, in addition to the ministry of planning and the ministry of interior. In addition to ministry of health (central level) a total of six governorates were selected by simple random sampling including the capital Baghdad with a seven districts were selected from those governorates also by simple random sampling and a total of twenty six health centers were selected from those districts, as well a total of seven hospitals were included in the study from all governorate and they were selected according to convenience. The interview has been done by using the health metrics network assessment tool version 4, in addition to a complementary assessment tools which are the PRISM package tools that were used at the district and primary health center levels. Based on the data collected and according to the health metric network assessment tool findings the overall health information system has laid in the adequate state (65.96%) with most of its comprising components function poorly. Data dissemination and use and data management categories were the weakest with a score of 50% and 53.3% respectively, while for the resources category it was found to be adequate 63.3%, and for that of HIS indicators, data sources and information product categories they were 73.3%, 66% and 69.6% respectively. For that of the PRISM tools and the findings obtained by them from the collected data the results revealed that a low data quality in term of accuracy with 29.03% at the facility level and 55.35% at the district level, while the completeness rate was excellent with a score 96.38% at the facility level and 98.23% at the district level, for that of the timeliness it was 70.43% timeliness at the district level. The information use for a given feedback at the facility was 50% and at the district was 82.12% and for observed meeting records it was 50% for the facility and 41.6% for the district level. For that of the functionality a 34.61and 67.30% of the facilities reported having a reminder mechanism for data completeness process and meeting a deadline for submitting monthly reports respectively, Data analysis was better at the district 85.71% than at the facility 81.7%, Data display were present in all of the facilities and districts. For the technical determinant the results showed 57%, 85.7%, 71.4% and 100% of the district respondents felt that the form is complex and difficult to follow, data software is a user - friendly, information technology is easy to manage and a comprehensive picture of the health system performance is captured by the system respectively,85.7% believed that the information system collecting information from some vertical programs and one district reported of no collection at all, in addition to that 100% reported the absence of a software that integrates data from different information systems and the available information technology doesn't provide full access procedure to district and senior managers. Regarding the behavioral determinants the results revealed that overall mean confidence for the information system tasks is 69.41% while for that of the task competence the overall mean competence level is 37.1%. Knowledge of checking data quality, knowledge of health information system rationale and problem solving showed results of 35.32% 37.68% and 2.98% respectively, and that of motivation level was 43.4%. Organizational determinants results revealed that the management functions at facility and district levels were almost absent, while for the perceived promotion of a culture of information it showed a total score of 63.96% and rewarding for a good performance was 56.83%. The activities for promotion of a culture of information are a 25% at the facility level and 28.75% at the district level. And that of supervision quality at the facility were (72.80%). Availability of resources revealed that 100% of the facilities have two or more computers and calculators respectively while only 57.7% have an internet access. Access to the electricity and water supply is very high, No facility reported of running out in registers in the last 12 months. Finally, the current study shows the importance for the need of further attention to be drawn to HIS, in addition to that, increasing the awareness and well coordinated efforts that need to be done to overcome weaknesses and to provide a well functioning HIS enabling for evidence based decision making and action provision in the health system.

On other hand Ginseng is an herbal plant is known for its therapeutic medical importance, it's used for different purposes in medical fields, that is effective against many diseases, act as a tonic and provide energy with significant reduction in mental and physical fatigue.Aims of the study To evaluate the central effects of Panax Ginseng and/or citicoline on normal healthy volunteers.Material and Method The subjects are randomly divided into four groups for assessment of central effects of Panax Ginseng and /or citicoline compared with placebo. The evaluation of the central effects was done by using the Leeds psychomotor battery tester for evaluating the psychomotor performance, workshop test was used to evaluate working memory function.The enrolled volunteers were randomly divided into the following groups : First group regarded as control group that treated with 500 mg/day of starch capsule as a single dose, second group, received Panax Ginseng capsule 500 mg /day, a third group received citicoline capsule 500 mg/day and the fourth group received Panax Ginseng capsule 500 mg/day plus citicoline capsule 500 mg/day as a single dose. All participants are followed for two consecutive weeks from starting treatments.ResultsIn the present study the placebo didn't have any central effect and MDA serum levels were not significantly change. Panax Ginseng has statistically significant effect on the most parameters of the psychomotor performance, working memory performance, as well as reduction of MDA serum levels. On the other hand, citicoline has statistically a significant effects on most parameters of the psychomotor and working memory function with statistically significant reduction of MDA serum levels.The combination of Panax Ginseng and citicoline have a highly statistically significant effect on all psychomotor performance, working memory performance and statistically significant reduction in the oxidative stress marker (MDA). ConclusionResults of the present study showed that combined effects of citicoline plus Panax Ginseng on central function produced more statistically significant effects on psychomotor performances, CFFF and working memory function than either Panax Ginseng or citicoline when they used alone, in addition to the combined effects of citicoline plus Panax Ginseng have a more significant effect on the oxidative stress,during mental stress.

Abstract: تتباين انظمة الرعاية لحديثي الولادة المطبقة ولكنها كلها تعتمد على وحدات الخدج الموجودة في مختلف بلدان العالم النامية والمتقدمة.انجزت هذه الدراسة المقطعية التقويمية في وحدات حديثي الولادة لردهات الولادة في مستشفيات بغداد (الكرخ والرصافة) مستثنين وحدات ال | Neonatal health care is provided via a variety of neonatal care units that are available globally both in different developing and developed countries.A cross - sectional evaluation study was conducted in all accessible fifteen neonatal intensive care units in Baghdad (Kharkh and Rosafa) maternity wards, excluding paediatric hospitals, during the period from November 2013 till the end of March 2014.The study aims : 1. Health care evaluation in neonatal intensive care units of maternity wards in Baghdad hospitals in terms of input (human and non - human resources) and outcome.2. Identifying causes of admissions and causes of deaths occurring in neonatal intensive care units The study consisted of two parts : A structure evaluation is using a check list to assess availability of human and non - human resources, covering infrastructure, manpower, equipment, and supplies; and an outcome evaluation study using hospital registration records review for causes of admission and causes of death in neonatal intensive care units during the year 2013.It was found that the mean number of specialist doctors in neonatal intensive care units was 2.1 and with standard deviation ±1.3, and college nurse was 2.2, with standard deviation of ±4.004, pharmacist was 0.4 with standard deviation of± 0.516 and for supplementary staff 1.5 with standard deviation of± 0.516.More than half 54% of nurses had no training in neonatal care.Concerning the availability of general equipment it was adequate except for computers 40%.Air conditioning, lighting and windows in addition to safe water supply was good 100% but ventilation was poor 67%, hand washing area was not always present 60% and free elbow operated water tubes were available in 6.7%. Availability of neonatal intensive care units special area was adequate for storage area 85.7% gowning area78.6%, while all the remaining areas were poorly available (resting room, examining room, mother room, boiling and autoclave room, area for mixing intravenous fluid and medication).Neonatal intensive care units were narrow and area/incubator ranging from 2.28m2 to 4.36m2/ incubator. Number of incubators was 246 with patient/ incubator ratio 53.6 : 1 and 27% of Neonatal intensive care units had no regular maintenance for incubators. Large Neonatal intensive care units >25 incubators were overcrowded, having below standards area/incubator, incubators covers only two third of neonatal care. Still up to one third of Neonatal intensive care units are getting their oxygen supply by cylinders, not pipes. Most equipment for individual use were poorly available. Most of Neonatal intensive care units emergency (cupboard) drugs and supplies were sufficiently available round the clock. Total admissions to Neonatal intensive care units were 13195 neonates. Male neonate's admissions 60% were higher than females 40%. Main causes of admission were Respiratory distress syndrome 43%, prematurity and low birth weight 19.4%, and Transient tachypnea 17.4%; birth asphyxia 4%, and hypoglycemia 3.8%, Congenital anomalies 3.7%, Neonatal jaundice 3%, while meconium aspiration and septicemia were the lowest1%. From all these admissions 74% were discharged well, (6%) were referred, while those discharged against medical advice were (4%) and the rest (16%) died. The main causes of death in Neonatal intensive care units were Respiratory distress syndrome 34%, prematurity and low birth weight 31% congenital anomalies 12%, birth asphyxia 8%, septicemia 4%, meconium aspiration 1% and 10% due to other unclassified causes. From this evaluation study, it can be concluded that there were Neonatal intensive care units with under staffing, undertraining and poor designing. Respiratory distress syndrome and prematurity were the main neonatal health problems.

Aim of the study : The present study investigated the influence of pretreatment with rosuvastatin and telmisartan alone or in combination in different doses on doxorubicin induced acute cardiotoxicity in rats using biochemical and histological approaches. Materials and methods : The animals were divided into eight groups of 5 animals each. The first group received no drug(s) po but a single dose of distilled water (7.5 ml/kg, ip) on day eight, which serves as the control group. The second group received no drug(s) po but a single dose of doxorubicin (15 mg/kg, ip) on day eight, and serves as doxorubicin only received group. The third and sixth group received rosuvastatin (2 , 10) mg/kg/day respectively for nine successive days, and on day eight, one hour after drug administration, a single dose of doxorubicin (15 mg/kg, ip) was given. The fourth and seventh group received telmisartan (2 , 4) mg/kg/day respectively for nine successive days, and on day eight, one hour after drug administration, a single dose of doxorubicin (15 mg/kg, ip) was given. The fifth and eighth group received both drugs, where the fifth group received both of rosuvastatin (2 mg/kg, po) and telmisartan (2 mg/kg, po), 1 hour apart, daily for nine successive days, and on day eight, one hour after drug administration, a single dose of doxorubicin (15 mg/kg, ip) was given. While the eighth group received both of rosuvastatin (10 mg/kg, po) and telmisartan (4 mg/kg, po), 1 hour apart, daily for nine successive days, and on day eight, one hour after drug administration, a single dose of doxorubicin (15 mg/kg, ip) was given.At day ten of the study, blood samples were taken for biochemical analysis, then animals were sacrificed and hearts were taken for histopathological observations. Results : Rats treated with doxorubicin showed cardiotoxicity as evidenced by significant elevation of serum cardiac troponin (CTn - I) level, lactate dehydrogenase (LDH) activity, serum malondialdehyde (MDA) level, and interluekine 17 (IL - 17) level associated with important histopathological alterations while pre - treatment with rosuvastatin and telmisartan elicited a significant decrease in the activities of all markers measured in comparison with doxorubicin treated group with pronounced resolution of Dox induced cardiac histological changes to a milder picture.Conclusion : These results suggest pretreatment with rosuvastatin and telmisartan alone or in combination provide a significant protective effect against acute - doxorubicin induced cardiotoxicity in rats represented by biochemical markers and histological approaches.

Abstract: تجارب الطفولة السيئة تشير الى اكثر مصادر الاجهاد شيوعا وشدة التي يعاني منها الاطفال في حياتهم المبكرة. من هذه الخبرات الاساءة، الاهمال، العنف بين الابوين او مقدمي الرعاية والعنف المجتمعي. وتبين ان الاجهاد الطويل في الطفولة له اثار طيلة الحياة على صحة | Adverse Childhood Experiences refer to some of the most intensive and frequently occurring sources of stress that children may suffer early in life. Such experiences include multiple types of abuse; neglect; violence between parents or caregivers and community violence exposure. It has been shown that prolonged stress in childhood has life - long consequences for a person's health and well - being; it may lead to serious problems such as alcoholism, depression, eating disorders, heart diseases, cancer, and other chronic diseases. Resilience is the ability to manage crises, difficult situations and developmental tasks. Research on resilience has identified several factors that strengthen the power and resources of children as well as promote their abilities to cope successfully with crises and internal and external problems. This cross - sectional study was conducted to estimate the effect of adverse childhood experiences and resilient factors on adults’ heath. It was done during the period from January 2013 through January 2014. The study sample was drawn from Baghdad City. Multistage sampling technique was used to choose 13 primary health care centers and eight colleges from three universities in Baghdad; the questionnaire was filled through a direct interview with the participants. In addition to that, teachers of seven primary schools and two secondary schools were chosen by a convenient method. A total of 1040 subjects were surveyed and 1000 responded. Their age ranged between 18 to 59 years (32.08±11.169). Females constituted a higher proportion (58.3%) of the study sample, 60% of this sample had university/diploma as the highest level of education. The results showed (during childhood) that seeing or hearing a parent or household member in home being yelled at, screamed at, sworn at, insulted or humiliated was reported in 469 (46.9%). A parent, guardian or other household member yelled, screamed or swear at, insulted or humiliated them was registered in 387 (38.7%). A parent, guardian or other household member spanked, slapped, kicked, punched the subjects was seen in 335 (33.5%). father's death (when the subject's age was 15 years or less) was reported in 104 (10.4%) of the participants, and 74.8 % of the subjects like to be the kind of people their parents were. The multiple linear regression models demonstrated that being in the fourth quartile (highest quartile) of household dysfunction - abuse score is expected to significantly increase depression symptoms score by a mean of (10.4) compared to subjects in the lowest (first quartile) of household dysfunction - abuse score, being in the fourth quartile of family bonding score is expected to significantly decrease depression symptoms score by a mean of ( - 22.5) compared to subjects in the first quartile, the same is correct for self - esteem score which increases by a mean of (21.484) for the fourth quartile of family bonding score compared to subjects with lowest (first quartile) after adjusting other explanatory variables. Logistic regression model showed that being in a higher level of family bonding (fourth quartile) is expected to reduce the risk of having chronic physical diseases by almost the half (odds ratio =0.57) and being exposed to a high level of household dysfunction and abuse (fourth quartile) is expected to increase the risk of having chronic physical diseases by 81%. A positive history of suicidal attempts showed a strong positive association with mean score of household dysfunction and abuse. Family bonding during childhood appears to be the most important resilient factor that protects adults against sedative or narcotic usage, mental disorders, suicide attempts, and chronic physical diseases during adulthood. Higher levels of exposure to adverse childhood experiences have a positive association with substances usage, suicide attempts, symptoms of mental disorders and chronic physical diseases in adulthood.

Abstract: هدف الدراسة : لتعيين العلاقة بين هرمون الهبيسيدين (hepcidin) (الهرمون المنظم لتوازن الحديد في الجسم والانترلوكين - 6 ( (interlukin - 6و علاقتها ببعض المتغيرات الكيميائية الحياتية عند المرضى المصابين بابيضاض الدم النيقاني الحاد ((AML قبل وبعد اكمال الجرعة الك | Acute myeloid leukemia (AML) is a clonal, malignant disease of hematopoietic tissues characterized by the accumulation of abnormal blast cells, especially in bone marrow, and impaired production of normal blood cells. The statistics show that this disease in men is more prevalent than women and this type of leukemia is increasing with age. Objectives : To assess biochemical changes related to iron status in acute myeloid leukemia pre and post course of chemotherapy and evaluate a relationship between serum hepcidin and IL - 6 in patients with acute myeloid leukemia pre and post chemotherapy and compare their levels to controls and their contribution on the pathogenesis of AML.Patients, Materials and Methods : The present study conducted at the National Center of Hematology and Baghdad Teaching Hospital in the Medical City from February 2014 to June 2014.The study included Fifty - eight (58) patients (30 male and 28 female) diagnosed with acute myeloid leukemia the age of patients range (15 - 65 years). Forty three (43)patients continued the study (24 male and 19 female) divided into two groups : Group (1) Patients with AML before starting chemotherapy. Group (2) the patients after 4 weeks of chemotherapy. Patient's treatment was done according to international protocol used in acute myeloid leukemia and called (3+7) where Doxorubicin was given from the first day to third day and Cyatrabine (Ara - C) was given from the first day to seventh day.Evaluationwas done on day (28) from starting chemotherapy to assess response of patients through bone marrow aspiration.All patients were subjected to complete history and physical examination. Diagnosis of AML patients was established by complete blood count and blood film, bone morrow aspiration and biopsy, hepcidin, interlukine - 6, C - reactive protein, ferritin, iron, total iron binding capacity, alkaline phosphstase, direct bilirubin were done for all patients.Forty - three (43) healthy subjects (24 male and 19 female) were enrolled in the study mainly from medical staff and their families. They were age and sex matched to patients group and considered as controls as ( Group 3).Results : • Serum hipcidin levels were significantly higher in(AML)patients (Group 2) compared to newly diagnosed(Group 1) and to healthy subjects ( P<0.0001).• Serum (IL - 6) levels were higher but not significant in(Group 1) compared to (Group 2) and significantly with healthy controls(P<0.214 and P<0.0001 respectively).• A significant increase in mean of serum ferritin levels were observed in (Group 2) compared to newly diagnosed patients (Group 1)(P<0.002) and the levels were significantly higher in newly diagnosed group compared to healthy controls (P<0.015).• Patients with (AML) during remission show significant decrease in levels of iron compared to newly diagnosed group(P<0.0001),while levels in healthy controls was higher values than both (Group 2) and (Group 1) (P<0.0001).• Total iron binding capacity (TIBC ) levels showed a significant decrease in (Group 2) after treatment compared to (Group 1) before treatment(P<0.0001) but the levels were significantly higher in healthy controls compared to (Group 1) and (Group 2) (P<0.0001).• Mean serum ALP levels showed highly increase in (Group 2) patients when compared to patients before treatment (Group 1)( P<0.0001), but the difference is not significantly higher between the newly diagnosis and controls (P<0.687).• A significant increase in mean serum direct bilirubin levels were observed in (Group 2) patients when compared to (Group 1) and healthy controls(P<0.0001).• Regarded to CRP levels in AML patients before and after treatment, the CRP levels increased in AML patients after treatment than newly diagnosed AML patients.Conclusions : Hepcidin and Interlukin - 6 may be used asprognostic for acute myeloid leukemia and also can play an important role in pathogenesis of AML.

Abstract: عجز لقلب المزمن : حالة تقويضية معقدة متمثلة بمرحلة تشخيصية متقدمة مدمرة ونهائية. ان عملية انتقال المرض من مستقر الى دنف القلب(اعتلال عام مع هزال) ليست مفهومة جيدا, وهناك عدد من العمليات المختلفة للحفاظ من عملية الهدر، وهي في معظمها حيث وجدت لتكون في وقت م | Chronic Heart Failure(CHF)is a complex catabolic state that carries a devastating prognosis. The transmission from stable disease to cardiac cachexia is not well understood. A number of different mechanism maintain the wasting process, most of which were found to be activated early in the development of CHF.Many of these pathways are initially activated to protect heart from damage and to compensate for impaired myocardial function. Mediators that have been implicated in this process include pro - inflammatory cytokines like interleukin 1 and 6, tumour necrosis factor - ? and the acute phase protein (C.R - P)these cytokines are activated during the course of CHF and maintaining the wasting process. Little is known about the mechanism leading to cardiac cachexia (C.C).Adiponectin and leptin are a protein hormones derived from adipocytes and they are important regulator of energy metabolism and body weight. Previous studies of CHF and C.C , had great differences between cachectic and non - cachectic patients.OBJECTIVETo study the relationship between Adiponectin, leptin & cytokines in cachectic &non cachectic HF patients & compared the results with coronary artery disease( CAD) patients with preserved left ventricular systolic function( LVSF) &healthy control to elucidate their roles in pathobiochemistary of cachexia, & to study the prognostic power of adiponectin in CHF, also to identify & confirm the role of proinflammatory cytokine(IL - 6& TNF - ?)& systemic inflammation marker (C - R.P)in the progression of CHF to cardiac cachexia.SUBJECTS &METHODE Studies were performed in Cardiology Clinics in Ibn Al - Betar hospital for cardiac surgery. Eighty eight subjects were divided into four groups each contain 22 subjects are enrolled in this study : 1st group : patient with HF(reduce LVSF)with cachexia include 5 females &17 males with age range from 47 - 76 years;2nd group : patients with HF(reduce LVSF)but without cachexia include 6 females& 16 males with age range from 34 - 70 years;3rd group : patients with CAD (preserved LVSF)include 11 males &11 females with age range from35 - 80 years & 4th group : consisted of healthy controls include 11male s& 11 females with age range from 36 - 65 years. The hormonal assay was done by ELISA.RESULTSPatients with CHF with cachexia had significantly higher concentrations of adiponectin than all other groups(p=0.004) ,that are associated with significant decrease in serum level of leptin(p=0.002), significant increase in serum level of IL - 6 when compared to other groups (p=0.0001)& significant increase in number of C - R.P positive compared only to healthy control(p=0.007),but serum level of TNF - ? is significantly decrease when compared to both CAD(p=0.023) &healthy control (p=0.0001)although it was non - significant decrease when comper to patient with CHF without cachexia.In the patient with CHF without cachexia, non - significant increase in serum level of adiponectin (when compared to patient with CAD with preserved LVSF& non - significant decrease compare to healthy control), while serum level of leptin was non - significantly decrease (when compared to patient with CAD with preserved LVSF & non - significant increase when compared to healthy control) associated with non - significant decrease in serum level of TNF - ? in comparison to CAD with preserved LVSF but significant decrease compared healthy control(p=0.011)while serum level of IL - 6 significantly increase in comparison to both CAD with preserved LVSF(p=0.01) &healthy control(p=0.008).In CAD with preserved LVSF non - significant decrease in serum level of adiponectin,while non - significant increase in serum level of both leptin , IL - 6 & TNF - ? when compared to healthy control. In this study there is strong significant positive correlation between adiponectin & TNF - ? in patients with CAD with preserved LVSF(r=0.615,p=0.002); while adiponectin was positively correlated with E.F% in patients with CAD with preserved LVSF(r=0.448,p=0.037).Finally there is significant positive correlation between TNF - ? & IL - 6 in patients with CHF with cachexia(r=0.466,p=0.029).CONCLUSIONCachexia, is a catabolic state of CHF associated with increase in serum adiponectin concentration, this may be consider as preservation of physical response to the changes in body fat but might also suggest that adiponectin plays a role in pathogenesis of cachexia, while cachexia associated with HF is not caused by enhance leptin release but, by increased level of adiponectin which is powerful predictor of cardiac cachexia.Cardiovascular Disease(CVD) is associated with elevated marker of systemic inflammation)C - R.P(that plays important role in disease progression& increase level of proinflamnmatory cytokine)IL - 6(has been reported as important pathogenic factor contributed to cardiac injury during CHF& progression to cardiac cachexia, although ,the level of TNF - ? is lower & has no relation to the degree of cachexia

Abstract: الفصا العظمي العقدي هو واحد من انواع التهاب المفاصل الموضعي. هو مرض المفصل التنكسي او الانحلالي, ويشمل الغضروف المفصلي والعظم تحت الغضروف, وهو يعتبر نوع من انواع امراض المناعة الذاتية. السبب الرئيسي للفصال العظمي العقدي غير معروف لكن هناك اسباب متنوعة مثل | Nodal osteoarthritis (NOA) is one type of the localised osteoarthritis that mostly occurs with postmenopausal women. It is degenerative joint disease, including articular cartilage and subchondral bone, it consider type of autoimmune diseases. The main cause of NOA is unknown but there are variety of causes like hereditary and metabolic, may initiate processes leading to loss of cartilage. The cartilage loss process usually lead to induce the immune system to release many of immune factors like cytokines , these factors lead to generation of immune response and inflammation in the joint. The NOA mostly occurs with postmenopausal women. It affects the smaller joint. Over several years, firm knobbly swellings form on the finger joints. These are caused by osteophytes so lead to bony enlargement and are known as Heberden's nodes when they are at the end joints of fingers (distal interphalangeal joints) or Bouchard's nodes when they are at the mid - finger joints (proximal interphalangeal joints). Once the nodes are fully formed, and not necessarily painful, they do limit the movement of the fingers significantly. NOA leads to the formation of bunions, rendering them red or swollen. Some people notice these physical changes before they experience any pain, but in advance cases, many of Symptoms may include like joint pain, stiffness and sometimes an effusion. When bone surfaces become less well protected by cartilage, bone may be exposed and damaged. As a result of decreased movement secondary to pain, regional muscles may atrophy, and ligaments may become more lax.Many studies have been done about inflammatory and biochemical markers in NOA and they found conflicting results. Objective1 - To evaluate serum adiponectin , interleukin - 6 (IL - 6) , anti cyclic citrullinated peptide (ACCP) and bone mineral density (BMD) in NOA.2 - To asses the CRP , RF and ESR in NOA.3 - To asses effect of age , gender , effect of BMI , smoking habit and duration of disease in NOA.Material and Method This study performed during the period from November 2013 to February 2014. These subjects were selected from patients attending the Rheumatology & Rehabilitation Consultation Unit at Al - Yarmouk Teaching Hospital. Patients and controls with hypertension, diabetes mellitus, malignancy, chronic disease of kidney, liver and any patients taken drugs that might effect the results have been excluded from the study.The laboratory tests were done in Al - Yarmouk teaching hospital laboratories and the laboratory research unit in collage of medicine / department of medical biochemistry. Subjects80 subjects (60 patients & 20 healthy controls) were enrolled in this study : A. First group : Patients with Nodal Osteoarthritis (NOA), No. = 60 (female =49 & male =11), rang of age (40 - 88) years.B. Second group : Healthy control group who had no history or clinical evidence of NOA or any other chronic disease like hypertension, DM and other chronic disease that might effect on the study data, No. 20 (female = 15 & male =5 ), rang of age (48 - 82) years.The patients were diagnosed as NOA according to the 2013 American College of Rheumatology (ACR) criteria, also the patients were diagnosed as normal, osteopenia and osteoporosis according to the 2013 American College of Rheumatology (ACR) criteria by measured of BMD (T - score) Normal : T - score (more than or equal - 1), Osteopenia : T - score ( - 1.1 - - 2.5) and Osteoporosis : T - score (less than - 2.5). The patients BMI were measured and determined as Normal (18 - 24.9 kg/m2), Over weight (24.9 - 29.9 Kg/m2), Obese grade - I (29.9 - 34.9 kg/m2) and Obese grade - II (more than 34.9 kg/m2) according to WHO 2012.MethodsELISA technique was used for the determination of serum adiponectin, IL - 6 and ACCP. Measurement of serum uric acid was done by spectrophotometric instrument. qualitative serological tests were used for determination of the CRP and RF also ESR determination were done in hospital laboratory. The BMI was determined by WHO equation's (2012) (weight/ (length) 2), also the BMD was determined by DXA scan according to ACR limits.Results obtained were subjected to statistical analysis by using SPSS and Excel program.ResultsLevels of serum adiponectin, IL - 6, CRP, ESR and BMI were significantly increased in NOA patients most than healthy controls, also the BMD (T - score) significantly decreased in NOA patients than healthy controls. But the age, gender, serum ACCP and uric acid were not significantly changed in NOA patients compared with healthy controls. Study of age, gende , BMI and duration of disease, found that they did not effect any parameters studied in NOA patients, only serum ACCP level was found to be significantly increased in females than males. Serum adiponectin level and CRP were significantly increased more in osteoporosis than osteopenia and normal. CRP was significantly increased in smoker than non smoker NOA patients.This study showed negative correlation between serum adiponectin and BMD, positive correlation between serum adiponectin and ESR, serum adiponctin and IL - 6 and IL - 6 and ESR in NOA patients. This study illustrated change in the status of the inflammatory markers like adiponectin, IL - 6 and other parameters in NOA disease. It illustrated effect of some of the factors like age, gender, BMI, BMD, smoking habit and duration of disease on development of NOA disease and on the status of the parameters studied. Also this study illustrated some correlation between the parameters in NOA patients.

Abstract: Acute coronary syndrome (ACS) is an insufficient supply of the myocardium with oxygenated blood in which atherosclerosis is an essential cause of myocardial ischemia. Adipokine biomarkers plays an essential role in the atherosclerosis and hence coronary artery disease. Serum Vaspin, Omentin - 1 and troponin I Fast are the biomarkers that believed to be independently associated with acute coronary syndrome.Objective : The study was carried out to evaluate : serum Vaspin,Omentin - 1 and Troponin I Fast in patients with acute coronary syndrome [ST - Elevation Myocardial Infarction(STEMI), Non - ST - segment Elevation Myocardial Infarction (NSTEMI),and Unstable Angina pectoris (UA)], that may help in guiding the diagnosis and treatment.Subjects, Materials and Methods : The study include a total (100) individuals; (75) patients with acute coronary syndrome (ACS) and (25) healthy control.A total number of 75 patients with acute coronary syndrome (ACS) (50 male ,25 female ) as : 25 patients with STEMI (22 male and 3 female) 25 patients NSTEMI(16 male and 9 female ) and 25 patients with unstable angina UA(12 male and13 female)were enrolled in this study all taken from Coronary Care Unit (CCU)at AL - Yarmouk Teaching Hospital.Each patient was clinically examined by the consultant cardiologist and the diagnosis was achieved by electrocardiograph (ECG), and cardiac enzyme levels.Venous blood sample (ten milliliters) was drawn from each patient and control after (10 - 12) hours overnight fasting, using a 10 ml disposable syringe between 9.00 and 11.00 A.M.The sample was divided into two portions one for testing Hb concentration and the other part was centrifuged to obtain serum, to be used for measuring the following variables : serum vaspin, serum omentin - 1 and Troponin I Fast, total cholesterol, triglyceride, High density lipoprotein cholesterol and low - density lipoprotein cholesterol, fasting blood sugar, serum creatinine and uric acid.Body mass index was calculated according to the following equation : BMI=weight/height2, also blood pressure was measured.Results : Serum vaspin and omentin - 1 levels were significantly lower in patients groups in comparison with control group, while serum Troponin I fast, total cholesterol, and low density lipoprotein cholesterol levels were significantly higher in patients with coronary artery disease than controls. Negatively significant correlation was found between serum vaspin and omentin - 1 with (BMI, total cholesterol and troponin I Fast).Conclusion : Serum Vaspin and Omentin - 1 levels were lower in acute coronary syndrome patients in comparison with control group, serum vaspin and omentin - 1 showed significant changes with the development and progression of acute coronary syndrome and would be valuable in the assessment of patients with acute coronary syndrome.Vaspin and Omentin - 1 may be used as a predictor of ACS.

Abstract: مرض السكري من النوع الثاني هو اكثر اشكال مرض السكري شيوعا ويتميز باختلال افراز الانسولين واختلال فعاليته ويكون مصحوبا بمشكله زياده الممانعه للانسولين(وهي الحاله التي يكون فيها كميه الانسولين الطبيعيه تكون غير كافيه لانتاج نفس الفعاليه الايضيه في الخلايا | Type 2 diabetes is the most common form of diabetes and is characterized by disorders of insulin action and insulin secretion, and associated with increase problem of insulin resistant which is the condition in which normal amounts of insulin are inadequate to produce a normal insulin response from fat, muscle and liver cells. Insulin resistance in fat cells results in hydrolysis of stored triglycerides, which elevates free fatty acids in the blood plasma. Insulin resistance in muscle reduces glucose uptake, whereas insulin resistance in liver reduces glucose storage, with both effects serving to elevate blood glucose. High plasma levels of insulin and glucose due to insulin resistance often lead to metabolic syndrome.The combination of hypertension, dyslipidemia, insulin resistance, hyperinsulinemia, glucose intolerance, and obesity, particularly central obesity, has been termed the “metabolic syndrome.” It has been proposed that this syndrome is a powerful determinant of type 2 diabetes and cardiovascular disease.Material and measurements : The study is designed to measure BMI, FBS, TG, HDLc, and c - peptide and insulin level. history of hypertension, age of patients and duration of diabetes are Also taken in to account. These parameters and measures applied for forty five patients with diabetes and thirty normal as control subjects.Results : - There is a positive significant Correlation between insulin level of the diabetic patient and BMI - there is Also a positive significant correlation between insulin level and C - peptide in diabetic patient (r=0.781) (p=0.0001) and in healthy control (r=0.599) (p=0.0001). - There is a positive significant Correlation between C - peptide level of the diabetic patient and BMI - There is a significant negative correlation between HDL with HbA1c, in diabetic patient (r= - 0.423) (p=0.006) and significant correlation of HbA1c with FBS - There is a positive significant Correlation between duration of diabetes and age of the patient(r=0.783) (p=0.0001) - There is a significant negative correlation between C - peptide and duration of diabetes in diabetic patient (r= - 0.310) (p=0.045) - There is a significant correlation between TG with FBS values. - There is a negative significant correlation between TG with HDL values. - 37.8% of diabetic patients had metabolic syndrome and no one of the control subjects had the criteria of (WHO).Conclusion : There were large percentage of diabetic patients with different BMI had metabolic syndrome as compared with the control subjects. There were strong correlations between insulin level (hyperinsulinemia) and risk of metabolic syndrome development and appearance of its complications. The risk of hyperinsulinemia and metabolic syndrome was well correlated with BMI than with HbA1c. Most of over weight and obese patients had high insulin level with different degrees of glycemic control and duration of disease. Large number of patient with metabolic syndrome were hypertensive as compared with diabetic patients with out the syndrome.

Abstract: الاستسقاء هو مصطلح يطلق على الجهاز الهضمي لتراكم السوائل في التجويف البريتوني (البطني) الناجمة عن كل من الامراض غير الخبيثة مثل تليف الكبد، والتهاب الصفاق السلي... الخ، والامراض الخبيثة مثل سرطان غشاء البطن المنتشر، وسرطان الثدي وسرطان المبيض. لقد تم | Ascites is a gastroenterological term for an accumulation of fluid in the peritoneal cavity caused by both non - malignant disease such as cirrhosis, tuberculous peritonitis..etc, and by malignant disease such as metastatic adenocarcinoma, breast cancer and ovarian cancer. The work in this thesis was done to evaluate the role of the multiple biochemical parameters and group of tumour markers in the differentiation between malignant ascites from non - malignant ascites. A number of parameters were obtained from (60) sixty patients : (30) thirty with malignant ascites and (30) thirty with non - malignant ascites (as controls), all patients admitted to the department of gastroenterology in Medical City - Baghdad Teaching Hospital, Oncology Teaching Hospital and Al - Amal Hospital between December 2013 and July 2014. The biochemical parameters and tumour markers which have been measured in the present study included : total protein, albumin, uric acid, calcium(Ca++), carcinoembryonic antigen(CEA),cancer antigen(CA19 - 9), cancer antigen(CA15 - 3), cancer antigen(CA125) and ? - human chorionic gonadotropin (? - hCG).The statistical analysis for the data obtained in the present study showed : 1 - Highly significant increase of CA15 - 3, ? - hCG and ascitic fluid/serum (A/S) total protein ratio in malignant ascitic fluid while there is significant decrease of serum ascites albumin gradient (SAAG) and serum ascites cholesterol gradient (SACG) in malignant ascites compared with non - malignant ascites patients (p<0.0005, p<0.0005, p<0.05, p<0.0005 and p<0.005 respectively). Thus the level of these parameters in ascitic fluid could be used as a good parameters in differentiation between malignant ascites from non - malignant ascites patients.2 - Significant increase in serum CA15 - 3 and ? - hCG level in malignant ascites patients compared to non - malignant ascites (p<0.05 and p<0.0005 respectively). 3 - Significant increase of CEA, CA19 - 9, total protein, albumin, uric acid and Ca++ level in ascitic fluid of malignant ascites patients compared to non - malignant ascites (p<0.0005, p<0.005, p<0.005, p<0.005, p<0.05 and p<0.05 respectively), thus the level of these parameters in ascitic fluid could be used as a helpful parameters in differentiation between malignant ascites from non - malignant ascites patients. 4 - Significant increase in serum of CEA, CA19 - 9, albumin, uric acid and Ca++ level in malignant ascites patients compared to non - malignant ascites (p<0.05, p<0.05, p<0.05, p<0.05 and p<0.05 respectively) while there is no significant differences in serum total protein level of malignant ascites compared to non - malignant ascites (p>0.05). 5 - CA125 level in ascitic fluid and serum of malignant ascites patients shows no significant increase compared to non - malignant ascites (p>0.05 and p>0.05 respectively), therefor CA125 test in ascitic fluid cannot be used as a parameter in differentiation between malignant ascites from non - malignant ascites patients.CA15 - 3, ? - hCG, (A/S) total protein ratio, SAAG and SACG can be considered as a good parameters in differentiation of malignant from non - malignant ascites, while CEA, CA19 - 9, total protein, albumin,Ca++ and uric acid level in spite of their increase in malignant ascitic fluid but this increase is not considered as a diagnostic factor and can be used as a helpful parameters in the differentiation between malignant from non - malignant ascites. CA125 has no useful role in diagnosis or differentiation between malignant from non - malignant ascites.

Abstract: Osteoporosis is a systemic disease of the skeleton that characterized by low bone mass and alteration in micro - architecture of bone tissue, which leads to an increase in brittleness with the ensuing predisposition of bone fracture. Global statistics show that women are more exposed to this disease than men and in particular at menopause. Like osteoporosis, type 2 diabetes mellitus (T2DM) is also greatly related to aging populations, and causes substantial morbidity and in some cases mortality. Diabetes mellitus could affect skeletal system and bone metabolism through multiple pathways and it has been considered as a major risk factor of osteoporosis.Objective : The aim of the study is to evaluate the usefulness of osteocalcin (OC), insulin - like growth factor I (IGF - 1) and bone mineral density (BMD) in postmenopausal women with type2 diabetes mellitus with or without osteoporosis and to compare the results of them with that of healthy control, in addition on studying role in the pathochemistry of osteoporosis and their validation as biomarkers of osteoporosis.Subjects & Methods : The study was performed during December 2013 to April 2014. Subjects were selected from outpatients attended National Diabetic Center (NDC)/ AL - Mustansiriyhiah University.Eighty - six (86) postmenopausal women aging (50 - 72) were included in this study. Subjects were divided into three group (I) included (25) healthy postmenopausal women without osteoporosis and diabetes mellitus (controls), Group (II) included (30) diabetic postmenopausal women without osteoporosis, Group (III) included (31) diabetic postmenopausal women with osteoporosis.Osteoporosis was diagnosed by measuring bone mineral density (BMD) by Dual energy X - ray absorptiometry (DXA). Also the levels of Fasting blood glucose (FBG), Calcium and phosphorus alkaline phosphatase (ALP) by spectrophotometer were measured in addition to measuring HbA1c level by NycoCard device using boronate assay affinity. While serum osteocalcin was measured using (ELISA) technique and IGF - 1 was measured using immunoradiometric assay. patients with malignant diseases, hyperthyroidism, hyperparathyroidism, osteomalacia, renal and hepatic diseases were excluded in addition to patients with chronic treatment with antiacids, estrogen, adrenal or anabolic steroids, anticonvulsants and anti - coagulants. Meanwhile, we ensured that all patients are not alcohol addiction and not smokers (passive & active).ResultsBone mineral density (BMD) was lower significantly in diabetic type II postmenopausal women with osteoporosis compared to diabetic type II postmenopausal women without osteoporosis and control group (0.68±0.04 g/cm2) , ( 0.87±0.03 g/cm2) , (0.89 ± 0.04 g/cm2), (P<0.001) respectively.The mean serum OC was lower significantly in diabetic type II postmenopausal women with osteoporosis group compared to diabetic type II postmenopausal women without osteoporosis group and control group (22.3±5.92 ng/ml), (27.2±5.96ng/ml), (27.3 ±3.49ng/ml) (P<0.001) respectively. Also the mean serum IGF - 1 was lower significantly in diabetic type II postmenopausal women with osteoporosis group compared to diabetic type II postmenopausal women without osteoporosis group and control group (46.6±8.41ng/ml), (65±8.48ng/ml), (88.2 ± 9.91ng/ml) (P<0.001) respectively.The mean of Fasting Blood Glucose was higher significantly in diabetic type II postmenopausal women with osteoporosis group compared to diabetic type II postmenopausal women without osteoporosis group, and control group (204.4±15.29 mg/dl), (187.2±13.45 mg/dl) , (93 ± 7.79 mg/dl) (P<0.001) respectively.The mean HbA1c was higher significantly in diabetic type II postmenopausal women with osteoporosis group compared to diabetic type II postmenopausal women without osteoporosis group, and control group (8±0.5), (7.5±0.53), (5.2 ± 0.33), (P<0.001) respectively.Also results showed no significant change in levels of calcium, phosphorus and alkaline phosphatase in the serum of diabetic type II postmenopausal women with osteoporosis group, compared to diabetic type II postmenopausal women without osteoporosis group and control group.There was a significant positively correlation between BMD with serum osteocalcin (r=0.43, P<0.001) and a strong positively significant correlation between BMD with serum IGF - 1(r=0.706, P<0.001). Also there was a significant negative correlation between BMD with HbA1c ( r= - 0.339, P=0.001), FBG(r= - 0.457, P<0.005) and Age (r= - 0.466, P<0.001).Also there was a positively significant correlation between serum osteocalcin with IGF - 1 (r= 0.34,p=0.007) and serum osteocalcin with BMD (r=0.43, P<0.001).Simultaneously there was a positively significant correlation between serum IGF - 1 and ostocalcin (r=0.34,p=0.007) and a positively significant correlation between serum IGF - 1 and BMD( (r=0.706, P<0.001). Also there was a negatively significant correlation between serum IGF - 1 with HbA1c (r= - 0.332,p=0.009), FBG(r= - 0.345,p=0.005) and Age (r= - 0.496, P<0.001).Conculsion Assessing the circulating levels of osteocalin and IGF - 1 may provide very useful information to diagnose or predict osteoporosis in Type 2 diabetic postmenopausal women.

Abstract: تعرف السمنه ب ترسب الدهون وخاصه في منطقه البطن الذي يرتبط ارتباطا وثيقا بالنظام الغذئي الناجم عن مرض خطير مثل السكري , اضطراب الدهون في الدم وارتفاع ضغط الدم التي توثر على صحه الانسان. ميتفورمين له تاثير ايجابي على التغيرات الايضيه الناتجه عن السمنه. علا | Background : Obesity is defined as the deposition of fat, especially in abdominal regions, which is closely related to serious diet - induced diseases such as type2 diabetes, dyslipidemia, and hypertension that affect human health. metformin has favorable influence on metabolic changes induced by obesity. Furthermore; treatment with metformin has good hepatoprotective effects against fatty changes induced by high fat diet. Moreover, it's interesting to mention that canagliflozin has comparable therapeutic effects to metformin on obesity induced metabolic disturbance but, unfortunately, it has not significant therapeutic impact on obesity induced hepatic steatosis. Interestingly, it has been found in the present study that use of metformin and canagliflozin in combination has superior promising impact on obesity induced metabolic and pathological changes.Aim of the study : The present study investigated the influence of metformin, canagliflozin, & their combination on body weight, food intake, glycemic indices, insulin sensitivity, and lipid profiles in diet - induced obese mice Materials and methods : The animals were divided into two groups.The first group feed with normal chow served as normal group {n=10}. The second group feed with high fat diet serve as high fat diet group {n=40} for two and half months and after the induction of obesity, then further subdivides into four groups. Group I : still feed with normal chow serve as control group{n=10}. Group II : received no drug(s) but only feeding with high fat diet, which serves as high fat diet group{n=10}. Group III : received a single dose of canagliflozin {10 mg/kg/po}, daily for 4 weeks by gavage method serves as canagliflozin group{n=10}. Group IV : received single dose of metformin {300 mg/ kg, po}, daily for 4 weeks by gavage method serves as metformin group{n=10}. Group V : received single dose of both canagliflozin {10mg/ kg, po} and metformin{300mg/kg, po}, daily for 4 weeks by gavage method serves as combination group{n=10}.At the end of the study, blood samples were taken for biochemical analysis, then animals were sacrificed and livers were taken for histopathological examination. Results : Mice feeding with high fat calorie content 60% for two and half months showed a significant increase in body weight, food intake, glycemic indices, homeostasis model assessment - insulin resistance (HOMA - IR), fasting plasma insulin and lipid profiles with important histopathological alterations. While, treatment with metformin - canagliflozin combination elicited a significant decrease in the all study and biochemical parameters with significant histopathological changes characterized by complete improvement on hepatic tissues. In comparison to metformin treatment also showed significant decrease in all study & biochemical parameters with good protective effect against obesity - induced hepatic steotosis. Whereas, canagliflozin also showed a significant decrease in all study and biochemical parameters with no significant improvement on hepatic tissue but the main thing that observed with canagliflozin is a superior effect on body weight with respect to metformin.Conclusion : treatment with metformin - canagliflozin combination provides a significant hepatoprotective effects against fatty changes induced by high fat diet. Moreover, this combination has favorable influence on metabolic changes induced by obesity. Whereas, each drugs alone show good improvement on many parameters including body weight, glycemic indices, insulin sensitivity, and lipid profiles with better improvement of hepatic tissue associated with metformin in contrast to canagliflozin that shows no significant improvement in hepatic tissue but, the excellent reduction in body weight seen in canagliflozin with respect to metformin.

Abstract: This study was conducted in pursuit of gaining a better understanding of the importance of hypothermia for cardiac surgery, and for CABG in particular. Most of the cardiac surgeons worldwide are accustomed to the use of mild hypothermia (32 - 35)°C for CABG procedures. Studies showed however that the risks of exposing the patient to mild hypothermia are similar to the risks endured during moderate hypothermia (28 - 32)°C. Objectives This study sought to weigh the benefits of mild hypothermia and moderate hypothermia against that of normothermia (35 - 37)°C concerning their impact on tissue oxygen consumption. Design This study is Prospective, randomized, comparative and purely observational and does not involve any intervention to the patient beyond the standard normal management. Setting At the department of physiology, college of medicine, Al - Mustansiriyah university in cooperation with the Iraqi Center for Heart Diseases and Ibn Al - Bitar Specialized Cardiac Surgery Center, in Baghdad, between December 2014 and April 2015. Patients, materials and methods Seventy patients, (55) males and (15) females, undergoing coronary artery bypass grafting surgery (CABG) were included in this study. Patients were allocated into three groups according to the surgeon's preferences; viz (normothermia, mild hypothermia and moderate hypothermia). Systemic complications associated with hypothermia were investigated via chemical analysis of the blood samples for renal and liver functions. Blood samples were collected two times during CPB from the arterial and venous ports of the oxygenator and were immediately analyzed to determine oxygen consumption and oxygen delivery. Results The decrease in the temperature for the hypothermic groups showed similar values of oxygen delivery (DO2) to that of normothermia (3537)°C at the same period during CPB. There were no noticeable changes between normothermia and mild hypothermia (32 - 35)°C. However, for moderate hypothermia (28 - 32)°C, there was a remarkable decrease in the oxygen consumption (VO2). The biochemical analysis for renal and liver functions in the normothermia and moderate hypothermia groups showed no significant differences between preoperative and postoperative results. However, in the group with mild hypothermia there was a significant change in results. Conclusion Moderate hypothermia rather than mild hypothermia proves to be of more benefit to the tissues when compared to normothermic conditions, as it significantly reduces tissue oxygen consumption. Moreover, even normothermia was found to be superior to mild hypothermia due to the latter's adverse effects on renal and liver functions while it maintains similar results with regards to oxygen consumption.

Abstract: اجري تخطيط القلب الكهربائي واخذت نتائج فحص الايكو لاربعة وخمسون مريض (اناث وذكور)، عمرهم المتوسط كان 51,1 ± 6,7 سنة؛ المدى كان يتراوح بين 35 - 66 سنة. المرضى الذي جندوا في الدراسة الحالية صنفوا الى اربع مجموعات : مرضى القلب الاقفاري الشرايين التاجية لوحده | ECG traces were recorded and echo findings were obtained for 54 patient (females were 15 and males were 39), their mean age was 51.1 ± 6.7 years; the range was 35 - 66 years. Patients that were recruited in the present study were classified into four groups : Patients with Ischemic Heart Disease (IHD) alone were labeled as group 1, Patients with IHD and Hypertension (HT) were labeled as group 2, Patients with IHD and diabetes mellitus (DM) were labeled as group 3, and Patients with IHD, HT, and DM were labeled as group 4. Fourteen age - matched apparently healthy subjects (mean age 48.6 ± 4.0 years) were chosen for comparison with group 1 patients. Patients' ECGs didn't show clear IHD before Treadmill test. Patients who showed clear ischemic changes within the treadmill test or during the rest time after completion of the treadmill test were sent to echo unit for structural / functional assessment of their hearts. Before stress test, simultaneous resting 12 lead ECG, arterial blood pressure, heart rate, height and weight of the patients were measured, age were recorded, smoking habit, and history of any cardiovascular disease. QT (The time interval measured from Q - wave onset the end of the T - wave), QT peak (The time interval measured from the Q - wave onset to the peak of the T - wave), TpTe (The time interval measured from the peak to the end of the T - wave)intervals were measured manually by tangent method on resting ECG. The dispersion of QT, QTp, TpTe intervals determined by the difference between minimal and maximal of these above measured intervals within 12 leads. The measured QT intervals were corrected for the subject's heart rate by using the standard Bazett's formula. In comparison with healthy subjects, QT dispersion (QTd) and QT peak dispersion (QTpd) of patients in group 1 were significantly higher (by 29% and 25% respectively) relative to their counterpart dispersion of healthy subjects, Tpeak - Tend dispersion (TpTed) of patients in group 1 was significant lower by 57% than TpTed of healthy subjects, QT interval and QTp interval of patients in group 1 was significantly longer (by 5% and 18% respectively) relative to their counterpart intervals of healthy subjects, in contrast, TpTe interval of patients in group 1 was significantly lower (by 27%) relative to their counterpart in healthy subjects. QT - intervals of patients in group 2, 3, and 4 are significantly higher (by 2%,4%, 3%) respectively than patients in group 1. QTp interval of group 3 was significantly higher than group 1, 2, and 4 by (4%, 6%, 4% respectively). No significant differences were observed in QTp interval among group 1, 2, and 4. TpTe interval of group 2, group 3, and group 4 patients were significantly longer by (16%, 6%, 14%) respectively relative to the TpTe interval in patients of group 1. QTd of patients in group 4 is significantly higher by (30%) than QTd of patients in group 1. QTp dispersion of group 4 is significantly higher by (26%) relative to QTp dispersion of group 1. TpTed of group 2 and group 4 were significantly higher (62% and 46% respectively) than TpTed of patients in group 1. LVMI of patients in group 2 and 4 were significantly higher (by 38% and 51% respectively) over the LVMI in patients of group 1. RWT of patients in group 2 and 4 were significantly higher (by 13% and 17% respectively) over the RWT of patients in group 1. PWT of patients in group 2, 3, and 4 was significantly higher (by 15%, 18%, and 21% respectively) over their PWT counterpart of patients in group 1. IVSTS was found to be significantly higher by (19% and 20%) of patients in group 2 and 4 respectively relative to patients in group 1. IVSTD was significantly higher by 24% in patients of group 4 only relative to the IVSTD of patients in group 1. IVSTS and IVSTD were significantly correlated with the QTd and QTpd in group 1. In group 2 patients RWT and PWT were significantly correlated with QTd and QTpd and IVSTD was significantly correlated with QT, QTp, and TpTe interval. In group 3 patients, IVSTD, ARD, and BMI were found to be significantly correlated with QTd and QTpd. significant correlation also was found in this group between RWT and QTp interval and IVSTS was correlated significantly with the QT and QTp intervals in group 4 patients.

Abstract: نسبة الاختلال الانبساطي الوظيفي للبطين الايسر عند مرضى داء السكري من النوع الثاني والكشف عنها بواسطة فحص الدوبلر النسيجي هدف الدراسة : للبحث عن نسبة الاختلال الانبساطي الوظيفي للبطين الايسر والذي يعد كعامل خطورة على وظائف القلب والاوعية الدموية عند مرضى | Our study about the left ventricular diastolic dysfunction in asymptomatic type 2 diabetic patients, detected by 2 - D and tissue Doppler echocardiography. Type 2 diabetes mellitus (T2DM) is the most common chronic disease, with several complications, affecting all systems and ages. The trends towards improving the longevity in diabetes are achieved by the glycemic control and prevention of complication. Left ventricular diastolic dysfunction (LVDDX) refers to mechanical abnormalities that impede effective volume filling during diastole. It has been described as an early sign of diabetic cardiomyopathy preceding the systolic damage. It can lead progressively to heart failure and is linked to increased mortality.Objective : The aim of this study is to estimate the percentage of left ventricular diastolic dysfunction in asymptomatic patients with type 2 diabetes mellitus detected by 2 - D and tissue Doppler echocardiography.Setting : This study is conducted by the department of physiology, college of medicine, Al - Mustansirirya university in cooperation with the unit of Echocardiography at Al - Yarmouk Teaching Hospital in Baghdad during the period from November 2013 to July 2014. Patients and methods : A total number of 130 subject were examined, where 38 were excluded and only 92 were included in this study, about 46 healthy subjects (control group) (with mean age of 47.07±7.6 year) and 46 patients with T2DM (with mean age of 49.39±5.7 year).Main outcome measures : The plan of the study consisted of the following steps : 1. History interview2. Physical examination3. Physical measurements including : body mass index (BMI), neck circumference (NC), waist circumference (WC), hip circumference (HC) , mid thigh circumference (MTC) calculation by measuring tape.4. Electrocardiography5. Conventional echocardiography and TDI6. Blood sample for hemoglobin A1C (HbA1c), fasting blood sugar (FBS), lipid profile.Results : Our study showed structural and functional changes in the left ventricle in a sample of diabetic patients. Diastolic dysfunction presents in 69.6% of diabetic patients, 41% were males and 59% were females. The mean age of the diabetic patients was 49±5.7 year. The mean duration of diabetes in asymptomatic normotensive type 2 diabetic patients was 7.6 ± 6.4 year. By TDI the diabetic patients in comparison to control group show lower E` average velocity (8.9±1.9 Vs 10.7±1.6 cm/sec)(P<0.0001), higher E/E` average ratio (7.4±1.7 Vs 6.4±1.3cm/sec) (P<0.04), lower E`/A` ratio (0.8±0.3 Vs 1.02±0.3)(P<0.004). While by conventional echo the diabetic patients show lower E velocity (63.7±13.4 Vs 72±19.9cm/sec) (P<0.01) and lower E/A ratio (0.9±0.3 Vs 1.17±0.4) (P<0.0001). Biochemical analysis show lower HDL (1.1±0.2mmol/l)(P<0.0001) and higher TG/HDL (1.8±1.4)(P=0.025). The study showed that diabetic patients had higher BMI 30.6±5.5 kg/m2 (P=0.052), higher neck circumference (40.4±3.9 cm) (P=0.034) and higher waist circumference (105.7±11.7 cm)(P<0.0001). All other values were not significant. Our study revealed that the highest percentage of LV diastolic dysfunction found in the group of diabetic patient with the highest duration of type 2 DM disease. The study revealed some correlations between some parameters of the study like : the duration of T2DM was positively correlated with A velocity (r= 0.29, p= 0.048), FBS was negatively correlated with A velocity (r= - 0.39, p= 0.008), FBS was negatively correlated with LVEDD (r= - 0.29, p= 0.049), FBS was negatively correlated with neck circumference (r= - 0.48, p= 0.0008), HDL was negatively correlated with IVS thickness (r= - 0.567, p= 0.00003) and mid - thigh circumference was positively correlated with A` average velocity (r= - 0.39, p= 0.008)Conclusion : 1. Type - 2 diabetes Mellitus is associated with a higher percentage of left ventricular diastolic dysfunction which is increased with the increased duration of DM. 2. Tissue Doppler echocardiography is a valuable tool in detecting LV diastolic dysfunction in asymptomatic normotensive diabetic patients with non significant features on conventional echocardiography.3. TDI is more sensitive and specific in detecting LV diastolic dysfunction in asymptomatic type 2 DM than pulsed wave flow Doppler.

Abstract: يتكون الجلد وكما هو معروف جيدا من عدة طبقات من الخلايا متجددة باستمرار عبر اعادة بناء نفسها ذاتيا مرة كل ثلاثون يوما من خلال دورة حيلتية متكررة وتقسم هذه الطبقات الى نوعين اساسية البشرة والادمة. يعتبر الكلوكوز امين سكر اميني بسيط ينبعث من عمليات الايض ال | It is well known that the skin is made up of multiple layers of cells that fare constantly going through self shedding and regeneration once every 30 days, or so in repeated cycles. The layers can be broadly divided into two sections : the epidermis and the underlying dermis. Glucosamine is an amino monosaccharide derived from cellular glucose metabolism. Glucosamine is a simple component or "building block" of more complex molecules. Glucosamine was considered to be an effective treatment for many joint diseases especially osteoarthritis. It is believed that glucosamine maintain healthy joint functions and rebuild damaged joint cartilage, tendons, ligaments and other connective tissue. It does this by stimulating the production of glycosaminoglycans (GAG’s) which are the structural components of cartilage and connective tissue else where in the body. On that basis, this study was designed to study the effects of glucosamine sulphate on the skin.Twenty male and twenty females adult mice (weighting between 23.3gm to 27.2gm), were divided into two equal subgroups (control and experimental); the drug was given at noon three hours after starvation it had been grinded and mixed with food and given as a single oral dose of 350mg/kg body weight per day for 35 successive days. Histological examination and statistical analysis of multiple sections of ventral and dorsal skin of male and female mice and of both subgroups were done by using hemotoxyline and eosin stain. Special stains were used to demonstrate the specific components of the skin as follows : for collagen fibers (Van Gieson's staining method), for elastic fibers (modified Taenzer - Unna Orcien staining method), and for ground substance (Alcian blue stain method).The results reveal that there was no particular change in the epidermis between the experimental and control groups. On the contrary there was a marked thickening with high cellular contents of both layers of the dermis (papillary and reticular).The dermis of the treated animals contains more collagen and elastic fibers. The predominant cell of the dermis was the fibroblast which was more obviously seen in the ventral skin of the treated animals. This study confirms practically that glucosamine sulphate induces significant structural changes in the skin of male and female mice. Using glucosamine sulphate clinically for medical conditions rather than arthritic diseases is now the target of most recent researches, its ability to decrease wrinkles in the aged skin and promotion of wound healing with less scar tissue is consider to be a light for dermatologist and plastic doctors, plus its effect to rebuild any aged, injured and diseased tissue in the body.

Abstract: يعتبر مرض الكبد الدهني غير الكحولي الاضطراب المزمن الاكثر شيوعا في الكبد واصبح تشخيصه في ازدياد مع زيادة وباء السمنة العالمي وقد تم تصميم الدراسة الحالية لدراسة الفوائد المحتملة للاديبونيكتين على النماذج الحيوانية من مرض.تم تطوير نموذجين من اضطراب الكبد | Non - alcoholic fatty liver disease is the most common chronic liver disorder whose prevalence has been on the rise with the worldwide increasing pandemic of obesity. The current study was designed to study potential benefits of the adipokine (adiponectin) on animal models of non - alcoholic fatty liver disease.Two models of the disorder were developed using two different approaches. In experiment 1 (25 mice, last 8 weeks), fatty change was induced using high fructose intake to simulate human - like diet induced obesity and fatty liver disease. In experiment 2 (25 mice, last 3 weeks), fatty liver damage was induced by using methionine - choline deficient diet. Animal body weights, absolute and relative liver weight, food consumption and fructose water consumption were recorded. Visceral (epididymal) fat and liver tissue were studied using routine hematoxylin and eosin staining and histochemical stains including Masson trichrome, Periodic acid schiff and reticulin stains. Morphological and morphometric changes were compared between animals treated with adiponectin, untreated diseased animals, and control healthy animals and a non - alcoholic steatosis activity score was used to evaluate the severity of liver damage. Random blood sugar and serum lipid levels were also included as biochemical metabolic parameters.High fructose intake resulted in larger visceral fat depots and weight gain, effects that were combated by adiponectin treatment despite increased food intake. Hepatic steatosis, inflammation, pyknotic pictures and fibrosis were reduced in adiponectin treated animals resulting in a lower activity score. Random blood sugar levels were normal in all animal groups but were significantly lower in adiponectin treated groups. TG and VLDL were alleviated with adiponectin treatment.Methionine - choline deficient diet resulted in emaciation of animals, much reduced visceral fat depots but a more severe form of liver fatty damage over a shorter period of time when compared to high fructose obese animal models. Weight loss was worsened after adiponectin treatment. Hepatic steatosis, inflammatory foci, ballooning degeneration and fibrosis were all exaggerated but remained significantly less severe with less activity score in adiponectin treated animals. Random blood sugar levels were normal in all animal groups but were significantly higher after adiponectin treatment. TG and VLDL was alleviated with adiponectin treatment.Adiponectin affects appetite, food consumption and body composition in healthy animals and animal models of non - alcoholic fatty liver disease through different mechanisms. It has beneficial effects in reducing body weight in obese animals but can modulate weight loss in lean animals on methionine - choline deficient diet. Adiponectin has autocrine/paracrine effects on visceral adipose tissue and can correct the dyslipidemic picture of fatty liver disease. The antisteatotic and antifibrotic effects of adiponectin carry greater therapeutic potentials in obesity - related liver disease.

Abstract: The adipocytokine leptin is a major player in the pathogenesis of diabetes mellitus and obesity. Since its discovery around 20 years ago, leptin has been; and still is; the subject of extensive research.The current study was designed to examine the effects of physiological doses of leptin on major organs involved in metabolism. The anatomical, histochemical, physiological, and biochemical effects of leptin were studied in healthy animals and in animal models of type 1 and type 2 diabetes.Eighty male albino mice were divided into three groups. The first group (A) consisted of healthy non - obese non - diabetic animals, a subgroup (A1) of which received leptin therapy to study its effects under normal conditions without metabolic disturbances. In the second group (B), a model of diet induced obesity and insulin resistance was developed using a combination of high fat diet and low dose streptozocin injection. In one subgroup (B1), the effects of leptin were studied under dietary manipulation after the discontinuation of high fat diet. In other subgroups, leptin effects were examined with continuous HFD with (B3) and without (B2) concomitant metformin therapy. The third group animals (C) represented a type 1 DM model developed by high dose streptozocin injection. A subgroup (C3) served as model control, not receiving any hormonal therapy. The others two subgroups received leptin treatment with (C2) and without (C1) concomitant insulin therapy.Statistical parameters for the study included the body weight, food and caloric consumption, adiposity index and specific organ weights and weight ratios. The epididymal fat pad, liver and pancreas were examined for gross anatomical and histological changes. Adipose tissue and some pancreatic sections were stained with H&E, liver sections were stained with periodic acid schiff stain, other pancreatic sections were stained with modified Gomori's aldehyde fuchsin. Random blood sugar and serum lipid levels and insulin tolerance test were also studied as biochemical parameters.Leptin therapy in healthy non - obese animals resulted in a reduction in food consumption, body weight, adiposity index and white fat pads weight. It also caused a reduction in the diameter and surface area of epididymal adipocytes. Serum TGL and LDL levels were significantly reduced. iiiThe same effects were seen in group B animals that underwent dieting or received metformin, but not in ones receiving leptin alone. Animal models of type 1 DM showed a moderate response to leptin therapy alone but the response was dramatically enhanced when treatment was combined with insulin. Sever weight loss and polyphagia of type 1 DM were greatly ameliorated by leptin therapy and there was an improvement in fat pad weights and adipocyte measurements. The hepatic glycogen content and insulin sensitivity were greater in animals treated with leptin (A1), on diet and leptin (B1) or metformin (B3) and in animals on leptin with insulin (C1). This was associated with significantly lower levels of random blood sugar. The pancreatic islet surface area was markedly reduced while the ? - cell/ ? - cell ratio was increased in treated animals.Leptin therapy can alter body weight and adiposity index by affecting appetite and food consumption via central and peripheral mechanisms involving the control of feeding behavior and manipulating the processes involved in carbohydrate and lipid metabolism. It can also correct the metabolic disturbances of type 2 DM but requires the concomitant use of metformin and/or the manipulation of dietary content of fat and carbohydrates. Much of its influence arises from its ability to enhance insulin sensitivity.Leptin also has a sparing effect on hepatic glycogen, favoring in turn the use of fatty acids for energy expenditure. Leptin effects on blood glucose are insulin dependent in most cases but can be insulin - independent in type 1 DM by utilizing alternative metabolic pathways for energy expenditure and interacting with hyperglycemia - inducing hormones.

Abstract: التهاب المفاصل الرثوي (Rheumatoid Arthritis) مرض جهازي التهابي مزمن يصيب المفاصل وتحديدا الاغشية الزلالية والتراكيب المفصلية، والذي يحدث للعديد من الناس وبنسبة تقارب 0.5 الى 1% من السكان في العالم. لوحظ خلال الدراسات الوبائية لمرض التهاب المفاصل الرثوي | Rheumatoid arthritis (RA) one of the most common systemic autoimmune diseases characterized by chronic joint inflammation and subsequent joint destruction. To date, it well known that RA is characteristic of the expansion of the synovium and infiltration of the inflammatory cells coupled with destruction of adjacent articular cartilage and bone. This is strongly dependent on CD4 T cell. CD4 Cells stimulate monocytes, macrophages, synovial fibroblasts, and other cells to produce cytokines such as tumor necrosis factor - ? (TNF - ?, interleukin - 1 (IL - 1), IL - 6, IL - 15, IL - 17 and metalloproteinases that produce tissue damage. TNF is a major inflammatory cytokine contributing to the pathogenesis of RA, which provides rational for development of anti - TNF biological agents in the treatment of RA.Recently have shown that IL - 37 is a key cytokine in regulating inflammatory response, mainly by inhibiting the expression, production, and function of proinflammatory cytokines. Objectives This study planned to evaluate the association of TNFRII and CD4 enhancer genes polymorphisms in development and severity of RA in Iraqi patients, evaluate IL - 37 in patients with RA and investigate the correlation between IL - 37 levels with disease activity and relation of inflammatory parameters (ESR, CRP, ACPA, and RF) with TNFRII, CD4 enhancer genes polymorphisms.Patients and methods This study was performed during the period from May to September 2015. The patients were attending the out patients' Clinic in Medical City/Baghdad Teaching hospital/rheumatology unit and the laboratory ELISA tests were done in nursing home hospital laboratory, polymerase chain reaction (RFLP) analysis was performed in the specialist private molecular laboratory (ASCO Lab) in Al - Harthia / Baghdad. Fifty patients and 50 apparently healthy control individuals, Patients received disease modifying anti rheumatic drugs (DMARDs) and newly diagnosed patients.The diagnosis of RA patients has performed under the supervision of rheumatic disease consultant physician at the consultation clinic of Baghdad teaching hospital of the medical city. Blood samples had taken from RA patients to measure (ESR), white blood cells count and hemoglobin. Also, analyze the serum levels of ACPA, RF screen CRP and estimate the levels of IL - 37 in patients and healthy individuals using ELISA test kits. TNFRII and CD4 enhancer genes polymorphisms genotyping had achieved by polymerase chain reaction restriction fragment length (PCR - RFLP).Results The results showed the estimation of RF by screening test revealed that its mean level was high among RA patients (168.87+31.62) in comparison with apparently healthy control (4.96+0.71) with highly significant difference (p<0.01). There was a higher positivity of Anti CCP in the patients sera (114.85+21.06) in comparison with apparently healthy control (1.71+0.13) (P<0.01). while the estimation of CRP showed that its level was higher among sera of RA patients (38.39+4.31) in comparison with healthy control group (16.49+2.51) (P<0.01). Furthermore, the ESR level in RA patients were higher than apparently healthy individuals (52.96+3.68) and (10.44+0.74) respectively with significance (P<0.01).The frequencies of the MM, MR, RR genotypes of TNFRII gene polymorphisms were 60%, 32%, 8% in RA patients and 52%, 42%, 6% in controls. There were no significant differences in the genotypes frequencies polymorphisms of the TNFRII 196 MR polymorphism between apparently healthy control and RA. The frequencies of AA, AG, GG genotypes of CD4 10845 A/G in patients was 36%, 42%, 22% and 8%, 44%, 48% in control group. There were significant differences in the genotypes frequencies polymorphisms of the CD4 10845A/G polymorphisms between apparently healthy control and RA patients (p<0.01). AA genotype were significantly more likely to develop RA (OR=1.355). There was significant increase in disease activity and severity in patients carries AA genotype (p<0.01).IL - 37 levels were elevated markedly in RA patients (101.31+10.41) compared with apparently healthy control (43.90+0.91) (p<0.01). More importantly, IL - 37 showed a significant correlation with disease activity (CRP) in RA patients (p<0.05). Also, IL - 37 show non - significant relationship with (MM, MR, RR) exon6 TNFRII in RA patients compared with controls, and non - significant difference between level of IL - 37 with CD4 10845 A/G genotypes compared with healthy control.Conclusion All findings suggested that TNFRII - 196R genotypes not associated with RA diagnosis. In addition, genetic polymorphisms at the CD4 enhancer gene are one of important factors that associated with susceptibility and severity of RA and can serve as a genetic marker for the risk of development of RA.
