Background: Obesity is an abnormal or increased fat accumulation in the body. Body mass index (BMI) defined as a person weight in kilograms divided by the square of his height in meters (kg/m 2 ). It is a very simple index that more commonly used to identify overweight and obesity in adults. For childhood, the amount of body fat differs from that an adult because it differs according to the age and to the sex, so the BMI ageand sexspecific percentiles are used. Obesity in children is a real health problem worldwide especially in developed countries, as well as, it increases in developing countries. Childhood obesity predispose to type 2 diabetics, hypertension, liver and renal disease, cardiovascular diseases and adult obesity. Objective: To detect the prevalence and possible risk factors for childhood obesity in primary schools in Baqubah city from age 6 to 12 years. Patients and Methods: The study was cross-sectional study conducted on a random sample of 6 primary schools from different localities in Baqubah city, followed by a systematic random sample of 308 children aged from 6 to12 years of both sexes. A questionnaire sent to the parents to get information on socio-demographic characteristics, dietary habits, physical activity, family history of obesity and parents education and job. Children's height (cm), weight (Kg), and BMI-for-age were measured. Child's weight status was categorized based on WHO 2007 Growth Reference. This study was included 308 child, the mean age was 9.32±1.9year, 51.9% of the children were males, and 49.1% were female the mean BMI was 18.36±4. Only 2.5% of the studied sample were underweight, while 73.4%, 14.3% and 9.4% were of normal, overweight or obese respectively. Results: About 48% of children in this study eat sweets, 48.5% do regular sports, 48.7% watch TV or mobile for more than 2 hours daily. It was found that 34.7% of children got positive family history of obesity, regarding educational level of parents 39% of mothers and 42.9% of fathers got primary level of education and 33.1% of mothers, 31.2% of fathers got higher than secondary level. Conclusion: The prevalence of overweight and obesity was 23.7% in primary schoolchildren in Baqubah city. The study supports the multi factorial etiology of obesity It showed that sedentary life style, positive family history and eating un healthy foods are risk factors.
背景:肥胖是指体内脂肪堆积异常或增加。体重指数(BMI)的定义是一个人的体重(公斤)除以他的身高(米)的平方(公斤/米2)。这是一个非常简单的指数,更常用来识别成年人超重和肥胖。对于儿童,体脂量不同于成年人因为它根据年龄和性别而不同,所以使用BMI年龄和性别特定百分位数。儿童肥胖是一个世界性的健康问题,特别是在发达国家,发展中国家的儿童肥胖问题也在增加。儿童肥胖易患2型糖尿病、高血压、肝肾疾病、心血管疾病和成人肥胖。目的:了解巴古拜市6 ~ 12岁小学生肥胖症患病率及可能的危险因素。患者与方法:本研究采用横断面研究方法,随机抽取巴古拜市不同地区的6所小学,随后系统随机抽取6 - 12岁男女儿童308名。向父母发送问卷,以获取社会人口特征、饮食习惯、体育活动、肥胖家族史以及父母的教育和工作等信息。测量儿童身高(cm)、体重(Kg)和年龄bmi。根据世卫组织2007年生长参考资料对儿童体重状况进行分类。本研究纳入308例儿童,平均年龄为9.32±1.9岁,男性占51.9%,女性占49.1%,平均BMI为18.36±4。研究样本中体重不足的比例仅为2.5%,正常、超重和肥胖的比例分别为73.4%、14.3%和9.4%。结果:约48%的儿童吃甜食,48.5%定期运动,48.7%每天看电视或手机超过2小时。调查发现,34.7%的儿童有肥胖家族史,父母受教育程度方面,39%的母亲和42.9%的父亲受教育程度为小学,33.1%的母亲和31.2%的父亲受教育程度为中学以上。结论:巴古拜市小学生超重和肥胖患病率为23.7%。这项研究支持了肥胖的多因素病因,它表明久坐的生活方式、阳性家族史和不健康饮食是危险因素。

Background: Chronic kidney disease is an international public health problem affecting 5– 10% of the world population. As kidney function declines, there is a progressive deterioration in mineral homeostasis, with a disruption of normal serum and tissue concentrations of phosphorus and calcium. Objective: To determine the effect on bone density by dexa scan and mineral derangement in chronic renal failure, by measuring calicium, phosphate, alkaline phosphatase and parathyroid serum ,total serum protein and Albumin levels and to determine bone density by dexa scan of bones. Patients and Methods: Cross sectional study was conducted in 75 patients with chronic renal failure . Blood was taken before dialysis session and measurements of serum calcium, phosphorus, serum alkaline phosphatase, .protein and albumin levels, and dexa scan to measure the bone density in these patients. Results: There was a significant correlation between Hypocalcemia and dexa scan results. Majority of patients had high serum phosphate levels (54.6%).and normal phosphate level in 40% while the hypophosphatemia result 5.33% and mean phosphate level is2.24 mmol/l. Total serum protein mean is 61.51 , 37.33% of them had hypoproteinemia and 62.66 % of them had normal serum protein. There was a significant correlation between dexa scan and vit D level, calcium, alkaline phosphatase, female gender, smoking and body mass index. Conclusion: The current study demonstrated that it can predict the chronic kidney diseasesMetabolic bone disorder from mineral levels before diagnosis by dexa scan.

Background: In diabetes, there are big concerns regarding impaired wound healing and other tissue disorders. The time and quality of wound healing are affected by many factors. One of the medical sciences ' aims is short-term wound healing with decreased side effects Herbal products are more valuable in both prophylaxis and curative in slowed diabetic wound healing as compared to synthetic drugs A considerable number of researches have shown that capers plant has distinct biological effects, including antioxidant, anticancer and antibacterial activity. Phytochemical analysis reveals C. Spinosa has large amounts of bioactive compounds, including polyphenolic compounds, which are essential for its health promoting effects. Objective: Histological evaluation of the effect of topical application of flavonoid extract of Capparis spinosa on the healing of incisional cutaneous wounds in alloxan-induced diabetic rats. Patients and Methods: A total of 30 healthy male Wistar rats weighing approximately 250300 g were used in this study. A surgical incisional wound with full skin thickness of 1.5 cm length were done in cheek skin of each rat. All rats were randomly divided into following groups: Group A: (10 healthy rats) received daily local application of the plant extract. Group B: (10 alloxan-induced diabetic rats) received daily local application of extract of the plant material. Group C: (10 alloxan –induced diabetic rats) where normal saline was applied locally instead of plant extract. Assessment of wound contraction was done as well as epithelial thickness inflammatory cell count and blood vessels count. Scarification of all animals was done for the healing periods (3 and 7 days), and specimens were prepared for histological analysis. Results: The results revealed that the recorded mean values of wound contraction increased with time in each group and that the highest mean values recorded in group A and B. Mean values of inflammatory cell count decreased with time lowest values recorded in group A after 7 days. Regarding epithelial thickness values increased with time. Blood vessels count showed highest mean value in group A at day 7. Conclusion: Results from this study showed that flavonoid rich extract of Capparis spinosa enhances wound healing process in diabetic rats.
