Background. During the last decade, vitamin D status was a major concern in the health and biomedical fields. This study assessed the level of awareness and knowledge regarding vitamin D and investigated the factors associated with the level of awareness such as knowing general facts about vitamin D, sources, benefit, and consequences of its deficiency. Methods. This cross-sectional study was conducted among the general population in Jeddah, Saudi Arabia, above the age of 18 years who were in 3 malls during the period of August and September 2017. A self-administrated questionnaire in paper forms was utilized and was divided into two parts to collect data. It was designed by the authors after revising the previous studies and validated by three pediatric consultants. An ethical approval was obtained from the ethical committee in King Abdulaziz University. We did an initial sample and tested it with the Cronbach test. The questionnaire had 2 parts with 19 questions. The first part was demographic information, and the second part was general information about vitamin D. An ethical approval was obtained from the ethical committee in King Abdulaziz University. Each participant received explanations about the aim of the study, and a verbal consent was taken from participants. The scoring system was as follows: for each right answer, 1 score was given and for wrong answer, 0 score was given, and the overall score was 14. The collected data were statistically analyzed using descriptive statistics using IBM SPSS statistics for windows version 20.0 (SPSS Inc., Chicago, IL). Result. Out of 1022 participants, 472 (46.1%) were aged 18–28 years, 830 (82.1%) were of Saudi ethnicity, 702 (68.7%) had a university degree, 275 (26.9%) attended high school, more than half were married (55.6%), and 54.4% had children. The majority of the participants agreed that vitamin D is important in the maintenance of bone and tooth health (88.4%). It is important in the maintenance of calcium and phosphates (76.6%), and it strengthens immunity (69.4%). Of the total participants, 86.2% were aware that sunlight exposure encourages vitamin D production in the skin. The overall knowledge mean score was 5.9 ± 1.2 (39.3%). Conclusion. This study highlighted a high level of inadequate knowledge of vitamin D deficiency among participants. There was a significant association between knowledge level and education level. The awareness of vitamin D deficiency is high regarding its benefits. The study revealed that participants who did not have children had the highest score for benefits. Nongovernment organizations and social workers may work together with government health-care organization to teach parents and children about the uses and benefits of vitamin D.

One-third of PICU admissions were complicated with AKI. AKI was associated with increased hospital mortality and the length of stay in both PICU and hospital.

BackgroundTransition to college is characterized by change, ambiguity, and adjustment compared to the previous lifestyle before entering college. Our study aimed was to determine the pattern of students’ physical exercise practices in the Kingdom of Saudi Arabia in the period before and during college attendance.MethodsA cross-sectional study was conducted among university students from fifteen universities in the Kingdom of Saudi Arabia on August 2017. The data were collected using an electronic questionnaire that was modified from questionnaires used in previous studies. Statistical analysis and data entry was performed with SPSS version 21. This study was approved by the Research Ethics Committee at King Abdulaziz University.Results417 college students completed the questionnaire and 77.2% were female. Slightly more than half of the participants (55.9%) were from King Abdulaziz University, and 59.7% were from healthcare specialties from different institutions. The mean age of the participants was 21.80 years old (SD = 2.75). The pattern of practicing physical exercise showed a significant decrease after enrollment in college (p = 0.000). The most common reason for not practicing exercise was time restrictions, accounting for 18.5% of all the reasons, while the most common reason for practicing exercise was to improve body shape, accounting for 48% of all the reasons.ConclusionsOur research found that there was a significant decrease in doing regular exercise during one’s college years in comparison to the school years prior to college. To address the decrease in physical exercise, we recommend organizing and promoting more awareness campaigns and providing suitable sports facilities and infrastructure.

Mitochondrial disorders (MIDs) shows overlapping clinical presentations owing to the genetic and metabolic defects of mitochondria. However, specific relationship between inherited mutations in nuclear encoded mitochondrial proteins and their functional impacts in terms of metabolic defects in patients is not yet well explored. Therefore, using high throughput whole exome sequencing (WES), we screened a chronic kidney disease (CKD) and sensorineural hearing loss (SNHL) patient, and her family members to ascertain the mode of inheritance of the mutation, and healthy population controls to establish its rare frequency. The impact of mutation on biophysical characteristics of the protein was further studied by mapping it in 3D structure. Furthermore, LC-MS tandem mass spectrophotometry based untargeted metabolomic profiling was done to study the fluctuations in plasma metabolites relevant to disease causative mutations and kidney damage. We identified a very rare homozygous c.631G > A (p.Val211Met) pathogenic mutation in RMND1 gene in the proband, which is inherited in an autosomal recessive fashion. This gene is involved in the mitochondrial translational pathways and contribute in mitochondrial energy metabolism. The p.Val211Met mutation is found to disturb the structural orientation (RMSD is −2.95 Å) and stability (ΔΔG is −0.552 Kcal/mol) of the RMND1 protein. Plasma metabolomics analysis revealed the aberrant accumulation of metabolites connected to lipid and amino acid metabolism pathways. Of these metabolites, pathway networking has discovered ceramide, a metabolite of sphingolipids, which plays a role in different signaling cascades including mitochondrial membrane biosynthesis, is highly elevated in this patient. This study suggests that genetic defects in RMND1 gene alters the mitochondrial energy metabolism leading to the accumulation of ceramide, and subsequently promote dysregulated apoptosis and tissue necrosis in kidneys.

Background: Approximately 50% of children with steroid sensitive nephrotic syndrome (SSNS) will suffer from frequent relapses or steroid dependency, prompting the use of so-called steroid-sparing drugs. In this pilot study, we compare the efficacy and safety of rituximab to oral cyclophosphamide as first-line steroid-sparing medications. Methods:A prospective open label non-randomized study of children with frequent relapsing or steroid-dependant SSNS. Exclusion criteria were steroid-resistant disease, prescription of immunosuppressive agents other than prednisolone or levamisole, evidence of impaired kidney function, leucopenia or active infection. The recruited children were allocated either to the oral cyclophosphamide (3mg/kg/day for 8 weeks) or intravenous rituximab treatment (two doses of 375 mg/m 2 /dose, 2 weeks apart) and were monitored for relapses and side effects for 12 months.Results: 46 subjects were included from two centers; 27 received cyclophosphamide and 19 received rituximab. One-year relapse-free survival was reached in 17 (58.6%) patients treated with cyclophosphamide compared to 16 (84.

Objectives: To record pediatric end stage renal disease (ESRD) patients’ quality of life (QOL) in relation to peritoneal dialysis (PD) and hemodialysis (HD). Chronic kidney disease is a rising global epidemic yielding worldwide prevalence of 11-13%. It could possibly lead to ESRD, thus imposing serious burdens on patients and reducing their QOL. These burdens may affect their family members as well. Methods: This cross-sectional study examined 23 pediatric ESRD patients aged 2-18 years who were undergoing peritoneal dialysis and hemodialysis at King Abdulaziz University Hospital, Jeddah, Kingdom of Saudi Arabia, in July 2018. Data were collected using the validated Pediatric Quality of Life Inventory™ 3.0 ESRD Module questionnaire. Results: The sample included HD (n=9, 40.9%) and PD (n=14, 60.9%) patients. According to the parent-proxy report, we found that the QOL among PD pediatric patients was significantly higher than HD patients ( p =0.045). Also, male HD patients had a significantly better QOL on the interaction subscale (70.83±15.95 compared to 30.00±24.00 for females [ p =0.023]). Conclusion: Quality of life was found to be better among PD pediatric patients in King Abdulaziz University Hospital, Kingdom of Saudi Arabia.
