However, the influence of some groups of food intake on CHD has shown inconsistent findings. Objectives: This study aimed to identify the relation of the dietary habits, Vitamin D, serum lipids, and anthropometric measures of the participants with CHD. Methods: A retrospective case-control study was conducted at Al-Remal Clinic, Gaza City. The study included 50 cases of symptomatic CHD and 50 controls, chosen by convenience sampling method. Data were collected by direct methods that included measurement of serum levels of lipids and Vitamin D, and indirect methods using a structured interview questionnaire. Results: The mean of servings per day of fruits and vegetables was lower in CHD patients than controls (P = 0.004, and P = 0.001, respectively). Vitamin D deficiency prevailed in CHD patients (odds ratio, 3.78;95% confidence interval, 1.65 - 8.65). The mean serum level of triglycerides was higher among cases (P = 0.02), while the mean of high-density lipoprotein cholesterol was lower in CHD patients (P = 0.001). Waist circumference (mean) was higher among cases (P = 0.01). Conclusion: Traditional risk factors including unhealthy diet, and Vitamin D deficiency could be associated with the development of CHD.展开更多

Due to the extraordinary content of organics and minerals, wastewater from slaughterhouses needs special care and treatment for safe disposal to the environment. Currently, wastewater from slaughterhouses in the Gaza Strip is discharged to the public networks without any treatment burdened central wastewater treatment plant, where partially treated effluent discharged to the sea. The aim of this research is to characterize the wastewater from Gaza slaughterhouse to identify the best approach for treatment. Samples from the slaughterhouse were collected during working hours and analysed for physical and chemical parameters. The pH, EC, DO, BOD, TSS, COD, Ammonia Nitrogen and TKN account for 7.1, 3300 μsm, 1.95, 2350, 3500, 4502, 30 and 154 mg/l, respectively. Wastewater from Gaza city slaughterhouse is within the range in comparison to other wastewater from slaughterhouses all over the world.展开更多
