Varieties of studies have been used to investigate the health benefits of Spirulina (Arthrospira platensis); however, more research is needed to examine if its nano form may be utilized to treat or prevent several chronic diseases. So, we designed this study to explore the effect and the cellular intracellular mechanisms by which Arthrospira platensis Nanoparticles (NSP) alleviates the testicular injury induced by diabetes in male Wistar rats. Eighty Wistar male rats (n = 80) were randomly allocated into eight groups. Group 1 is untreated rats (control), Group 2 including STZinduced diabetic rats with 65 mg/kg body weight STZ (STZ-diabetic), Group 3-5: including diabetic rats treated with NSP1, NSP2, and NSP3 at 0.25, 0.5, and 1 mg/kg body weight, respectively, once daily orally by the aid of gastric gavage for 12 consecutive weeks and groups 6-8 include normal rats received NSP (0.25, 0.5, and 1 mg/kg body weight once daily orally. The identical volume of normal saline was injected into both control and diabetic rats. After 12 weeks of diabetes induction, the rats were killed. According to our findings, NSP administration to diabetic rats enhances the total body weight and the weight of testes and accessory glands; in addition, NSP significantly reduced nitric oxide and malondialdehyde in testicular tissue improved sperm parameters. Intriguingly, it raises testicular GSH and SOD activity by a significant amount (p < 0.05). As well, Oral administration of NSP to diabetic rats resulted in a decrease in the blood glucose levels, HA1C, induced in the diabetic group, which overcame the diabetic complications NSP caused down-regulation of apoptotic genes with upregulation of BCL-2 mRNA expression (p < 0.05) and prominent up-regulation of steroidogenesis genes expression level in testes in comparison to the diabetic rats which resulted in improving the decreased levels of testosterone hormone, FSH, and LH induced by diabetes. In the same way, our histopathological findings support our biochemical and molecular findings; in conclusion, NSP exerted a protective effect against reproductive dysfunction induced by diabetes not only through its high antioxidant and hypoglycemic action but also through its down-regulation of Apoptotic genes and up-regulation of steroidogenesis regulatory genes expression level in diabetic testes.

Objectives:To understand the knowledge, attitude, and practice of healthcare practitioners in Saudi Arabia, with regard to vitamin D supplementation.Methods:A cross-sectional survey was conducted among healthcare practitioners in the Tabuk region of Saudi Arabia between January 2015 and December 2016. A questionnaire assessing knowledge, attitude and practice with regard to prevention of vitamin D deficiency was distributed to 100 healthcare practitioners.Results:There was a good understanding of the importance of vitamin D deficiency; and overall practices were good. The average knowledge score was 4.75/8 (range 2-7), largely due to 85% of recipients identifying sun exposure between 6-7 am as the optimal time. There was a lack of understanding also, that as little as 10 minutes exposure is of benefit.Conclusion:This study highlights the need for distribution of the recommendations for vitamin D supplementation in KSA, as widely as possible. This study suggests that healthcare practitioners understand the importance of correction of vitamin D deficiency. Deficiencies in knowledge with regard to sun exposure were identified. Dissemination of this information is, therefore, likely to impact significantly on the practice of a receptive clinical population.

We aimed to identify the variation in the clinical background of children diagnosed with type 1 diabetes mellitus (T1DM) at King Salman Military Hospital (KSMH), Tabuk City, Kingdom of Saudi Arabia, from 2000 to 2010. Methods: This retrospective observational study was based on the clinical records of pediatric diabetes outpatients at KSMH. All children aged <12 years who were diagnosed with T1DM and were followed up at the diabetes clinic from 2000 to 2010, were enrolled. The local variables associated with the clinical presentation in these patients, including age, sex, body mass index (BMI), and season of onset, were evaluated. Results: Of 313 patients recruited, female patients were predominant (p = 0.002). The mean age of onset was 6.46 years (standard deviation, 3.02). One-third of the newly diagnosed patients were overweight (35.5%). Diabetic ketoacidosis (DKA) was the presenting feature in 38.0% of patients, wherein female patients and those aged 0 -3 years exhibited the highest likelihood of developing DKA (odds ratio, 1.7 and 2.9, respectively). Moreover, underweight children had a greater DKA incidence than healthy, overweight, or obese children (p = 0.02). Conclusion: This study provides additional data on T1DM in the population of the Kingdom of Saudi Arabia. In particular, we found a female predominance at presentation as well as 2 peaks for age at onset. Moreover, the BMI was lower in younger age groups overall, but was greater in older boys. Furthermore, the DKA rates were high in younger children. Thus, our data confirm the presence of variable clinical patterns in the Kingdom of Saudi Arabia, which requires further epidemiological analysis using national registry data.How to cite this paper: Albishi, L.A., Altoonisi, M.M., Alblewi, S.M., Osman, R.H., Ahmed, N
