Automated insulin delivery (AID) systems have improved glycemic control in individuals with type 1 diabetes (T1D). The “advanced hybrid closed loop” (AHCL) stands out as the most recent development in AID systems for T1D management. In a real-world clinical environment, we retrospectively evaluated the AHCL MiniMed™ 780G system's effectiveness to achieve and sustain glycemic control over a 12-month period in 22 adult T1D subjects. Within just 14 days of activating the automatic mode, the AHCL MiniMed 780G system showed rapid improvement in glycemic control, which persisted for 12 months. These findings underscore the effectiveness of AHCL systems in achieving and preserving optimal glycemic control in adults with T1D over a very long follow-up.

Obesity is a global epidemic associated with chronic inflammation, oxidative stress, and metabolic disorders. Bariatric surgery is a highly effective intervention for sustained weight loss and the improvement of obesity-related comorbidities. However, post-surgery nutritional deficiencies, including vitamin E, remain a concern. This study investigates the role of single-nucleotide polymorphisms (SNPs) in genes related to vitamin E transport and bioavailability in determining vitamin E levels post bariatric surgery. A cohort of 140 patients with obesity undergoing bariatric surgery was analyzed. Serum vitamin E levels were measured before and one year after surgery, and SNPs in genes associated with vitamin E transport and metabolism were genotyped using PCR, DHPLC, and sequencing methods. Associations between SNPs, haplotypes, and vitamin E levels were statistically evaluated. Significant associations were observed between the APOE rs7412 SNP and serum vitamin E levels. The rare T allele was linked to lower vitamin E levels post surgery, with an increased frequency in patients with severe deficiency (<11.6 μmol/L). Haplotype analysis of APOE revealed that the ε2 haplotype (T-T) was strongly associated with vitamin E deficiency. Other SNPs, including CD36 rs1761667, SCARB1 rs4238001, and ABCA1 rs4149314, were also linked to changes in vitamin E levels, suggesting that an impaired bioavailability and transport can be the reason for low vitamin E levels post surgery. Genetic polymorphisms in APOE, CD36, SCARB1, and ABCA1 significantly influence vitamin E status after bariatric surgery. These findings highlight the importance of personalized supplementation strategies considering patients’ genetic profiles to mitigate the risk of vitamin E deficiency and related complications.
