Bariatric Surgery as Treatment Strategy of Obesity in Saudi People: Effects of Gut Microbiota.

Obesity prevalence is rising globally, as are the number of chronic disorders connected with obesity, such as diabetes, non-alcoholic fatty liver disease, dyslipidemia, and hypertension. Bariatric surgery is also becoming more common, and it remains the most effective and long-term treatment for obesity. This study will assess the influence of Laparoscopic Sleeve Gastrectomy (LSG) on gut microbiota in people with obesity before and after surgery. The findings shed new light on the changes in gut microbiota in Saudi people with obesity following LSG. In conclusion, LSG may improve the metabolic profile, resulting in decreased fat mass and increased lean mass, as well as improving the microbial composition balance in the gastrointestinal tract, but this is still not equivalent to normal weight microbiology. A range of factors, including patient characteristics, geographic dispersion, type of operation, technique, and nutritional and caloric restriction, could explain differences in abundance between studies. This information could point to a novel and, most likely, tailored strategy in obesity therapy, which could eventually be incorporated into health evaluations and monitoring in preventive health care or clinical medicine.

Molecular Screening via Sanger Sequencing of the Genetic Variants in Non-Alcoholic Fatty Liver Disease Subjects in the Saudi Population: A Hospital-Based Study.

Non-alcoholic fatty liver disease (NAFLD) is one of the most common liver diseases, along with steatosis and non-alcoholic steatohepatitis (NASH), and is associated with cirrhosis and hepatocellular carcinoma. Candidate gene and genome-wide association studies have validated the relationships between NAFLD, NASH, PNPLA3, TM6SF2, and HFE. The present study utilized five polymorphisms in three genes: PNPLA3 (I148M and K434E) TM6SF2 (E167K), and HFE (H63D and C282Y), based on undocumented case−control studies in the Saudi Arabian population. A total of 95 patients with NAFLD and 78 non-NAFLD subjects were recruited. Genomic DNA was isolated, and polymerase chain reaction and Sanger sequencing were performed using specific primers for the I148M, K434E, E167K, H63D, and C282Y. NAFLD subjects were older when compared to controls and showed the significant association (p = 0.0001). Non-significant association was found between gender (p = 0.26). However, both weight and BMI were found to be associated. Hardy−Weinberg equilibrium analysis confirmed that H63D, I148M, and K434E polymorphisms were associated. Genotype analysis showed only K434E variant was associated with NAFLD and non-NAFLD (OR-2.16; 95% CI: 1.08−4.31; p = 0.02). However, other polymorphisms performed with NAFLD and NASH were not associated (p > 0.05), and similar analysis was found when ANOVA was performed (p > 0.05). In conclusion, we confirmed that K434E polymorphism showed a positive association in the Saudi population.

Preparedness of current and future Saudi Pediatricians to face vaccine hesitancy: Cross-sectional study within the capital city of Saudi Arabia, Riyadh.

BACKGROUND: Vaccines have helped in eradicating many communicable diseases. They are considered major players in preserving children's health. However, concerns about vaccines' ingredients and safety became hot topics globally. With doubt, some parents became hesitant to vaccinate their children. A recent study documented high prevalence of vaccine hesitancy among Saudi parents. OBJECTIVES: This study aims to explore preparedness of current and future pediatricians to face vaccine hesitancy, a growing public health issue in Saudi Arabia. METHODS: This study adopted non-interventional cross-sectional online questionnaire specifically designed to encompass general vaccine hesitancy related questions including Covid-19's vaccines. RESULTS: The study recruited 119 participants form three main tertiary centers in Riyadh. Trainees were the majority with pediatric consultants representing 22%. Females were more than half of total participants (53%). Although familiarity with the term "vaccine hesitancy" was common, it was affected by training level. Among participants, 66% heard about it from social media. Furthermore, only 32% received designated training. Knowledge was suboptimal among all levels except for those who received formal training. Despite 80% encountered vaccine hesitancy, only 55% consider it a common public health issue. Attitude toward vaccine hesitant parents was negative among male physicians (odds ratio of 2.3, P value 0.045). Additionally, majority consider it a form of child neglect (95%). In regard to COVID19's vaccine, 31% were reluctant to get vaccinated themselves. CONCLUSION: Pediatric workforce in Saudi Arabia commonly encounters vaccine hesitancy. The strong stand against vaccine hesitant parents might affect rapport with families. Sub-optimal knowledge, negative attitude and emerging COVID19 vaccine hesitancy might negatively impact future efforts. Tailored training and innovative educational platforms are essentials to address vaccine hesitancy in Saudi Arabia.
