Awareness About the Benefits of Post-bariatric Surgery in Diabetic Patients in Makkah Almukarramah, Saudi Arabia

AIM

To measure awareness about the benefits of post-bariatric surgery, which is a shortening of the gut in order to lose weight in diabetic patients in the Makkah region, Saudi Arabia.

METHODS

A cross-sectional survey was conducted among diabetic patients aged 18-65 from February to July 2023. An online questionnaire via Google Forms was distributed and used to assess the participants' awareness of the benefits of post-bariatric surgery for diabetic patients.

RESULTS

Overall, 388 participants (56.40% female, 43.60% male) were surveyed. Most participants (91.5%) showed awareness of gastric sleeve surgery, while a significant proportion (85.8%) recognized obesity as a disease. A majority of participants (80.90%) showed awareness of the association between obesity, diabetes, and high blood pressure. However, only 46.10% of participants showed awareness of eligibility criteria associated with bariatric surgery. The majority recognized the effectiveness of bariatric surgery for weight loss but did not consider it the first choice, emphasizing a preference for non-surgical weight loss strategies.

CONCLUSION

Participants demonstrated good knowledge about obesity and its implications for health. They also demonstrated good knowledge about bariatric surgery as an effective weight reduction method but expressed a preference for non-surgical methods, which reflects their awareness of the complications of bariatric surgery. However, the results showed a lack of awareness of postoperative indications and lifestyle changes, thus highlighting the need for comprehensive patient education and counseling.

Effect of Cytochrome P450 Family 2 Subfamily R Member 1 Variants on the Predisposition of Coronary Heart Disease in the Chinese Han Population

Propose: Cytochrome P450 family 2 subfamily R member 1 (CYP2R1) variations can affect the activity of 25-hydroxylase, resulting in the deficiency of 25(OH)D, which leads to an increased incidence and mortality of coronary heart disease (CHD). The purpose is to assess the influence of CYP2R1 variants on CHD risk among the Chinese Han population.

Methods: A total of 508 CHD patients and 510 healthy controls were enrolled. The MassARRAY platform completed genotyping of CYP2R1 variants. Odds ratios (ORs) with 95% confidence intervals (CI) were calculated using logistic regression analysis.

Results: Rs6486205 (OR = 1.25, 95% CI: 1.05–1.50, p = 0.014), rs10741657 (OR = 1.29, 95% CI: 1.08–1.54, p = 0.005), and rs2060793 (OR = 1.27, 95% CI: 1.06–1.51, p = 0.009) were associated with the increased susceptibility to CHD in the whole subjects. Interestingly, the relationships between these variants and CHD risk were observed in the subjects with age >60 years, males or non-smoker. Additionally, the haplotypes A_rs10741657A_rs2060793 and G_rs10741657G_rs2060793 had the higher risk of CHD, and the combination (rs6486205 and rs10741657) was the best multi-locus model.

Conclusion: Our study suggested the contribution of CYP2R1 polymorphisms to the increased CHD predisposition in the Chinese Han population. Furthermore, the risk association was related to confounding factors for CHD, including age, sex, and smoking. These findings might help to strengthen the understanding of the CYP2R1 gene in the occurrence of CHD.
