Amelioration of Insulin Resistance after Delivery Is Associated with Reduced Risk of Postpartum Diabetes in Women with Gestational Diabetes Mellitus.

Background: Identifying risk factors for postpartum type 2 diabetes in women with gestational diabetes mellitus (GDM) is crucial for effective interventions. We examined whether changes in insulin sensitivity after delivery affects the risk of type 2 diabetes in women with GDM. Methods: This prospective cohort study included 347 women with GDM or gestational impaired glucose tolerance, who attended the follow-up visits at 2 months postpartum and annually thereafter. Changes in insulin sensitivity were calculated using the Matsuda index at GDM diagnosis and at 2 months postpartum (ΔMatsuda index). After excluding women with pregestational diabetes or those followed up only once, we analyzed the risk of postpartum type 2 diabetes based on the ΔMatsuda index tertiles. Results: The incidence of type 2 diabetes at the two-month postpartum visit decreased with increasing ΔMatsuda index tertiles (16.4%, 9.5%, and 1.8%, P=0.001). During a 4.1-year follow-up, 26 out of 230 women who attended more than two follow-up visits (11.3%) developed type 2 diabetes. Compared to the lowest tertile, subjects in the highest ΔMatsuda index tertile showed a significantly reduced risk of type 2 diabetes (hazard ratio, 0.33; 95% confidence interval, 0.12 to 0.93; P=0.036) after adjusting for confounders. Conclusion: Improvement in insulin sensitivity after delivery is associated with a reduced risk of postpartum type 2 diabetes in women with GDM. Postpartum changes in insulin sensitivity could be a useful prediction for future type 2 diabetes development in women with GDM.

Theragnostic utility of continuous glucose monitoring in post-gastrectomy hypoglycemia.

Diagnosing post-gastrectomy hypoglycemia is challenging, often relying on medical history with documented low plasma glucose levels. Here, we present three cases of patients who presented a high probability of post-gastrectomy hypoglycemia diagnosed and managed successfully using "theragnostic" continuous glucose monitoring and alpha-glucosidase inhibitors. In the first week, patients maintained their current lifestyle without medical intervention; in the second week, voglibose 0.2 mg before meals was prescribed. Continuous glucose monitoring data from the first week confirmed the diagnosis with multiple hypoglycemic events after postprandial peaks, whereas data from the second week showed reduced hypoglycemic events and lower glycemic variability, demonstrating voglibose's therapeutic effect. This report highlights the effective management of post-gastrectomy hypoglycemia using voglibose and theragnostic continuous glucose monitoring, showing its potential benefits and safety for similar cases.

Patient preference, efficacy, and compliance with zoledronic acid for glucocorticoid-induced osteoporosis in patients with autoimmune diseases.

PURPOSE: We evaluated the preference, patient satisfaction, and efficacy of zoledronic acid compared with oral bisphosphonates (BPs) for glucocorticoid-induced osteoporosis (GIOP) in patients with autoimmune diseases. METHODS: We enrolled 50 patients with new fractures or osteoporosis detected on follow-up bone densitometry after at least 1 year of oral BP use among patients diagnosed with GIOP during treatment for autoimmune diseases. After 1 year of zoledronic acid treatment, patients completed a survey for preference and satisfaction assessment. Treatment efficacy was analysed by comparing bone mineral density changes and fractures with those in a control group of patients who continued oral BP use. RESULTS: Age, sex, treatment duration, and medication history did not differ significantly between the two groups. Among the participants, 86.7% preferred and were more satisfied with intravenous zoledronic acid than with oral BPs, primarily because of the convenience of its administration interval. Only two patients (4%) reported infusion-related adverse events with zoledronic acid. Furthermore, no significant differences were observed in the annualized percentage change in the bone mineral density of the lumbar spine, femur neck, and hip between patients receiving zoledronic acid and those receiving oral BPs. The occurrence of new fractures was consistent across both groups, with two cases in each, showing no significant differences. CONCLUSION: Patients showed a preference for and greater satisfaction with zoledronic acid, and its efficacy in treating osteoporosis was comparable to that of oral BPs. Therefore, zoledronic acid is a suitable treatment option for GIOP in patients with autoimmune diseases.

Risk of thyroid cancer associated with glucagon-like peptide-1 receptor agonists and dipeptidyl peptidase-4 inhibitors in patients with type 2 diabetes: A population-based cohort study.

AIMS: To determine the potential association between the use of either glucagon-like peptide-1 receptor agonists (GLP-1RAs) or dipeptidyl peptidase-4 (DPP-4) inhibitors, and the risk of thyroid cancer in individuals with type 2 diabetes. MATERIALS AND METHODS: This population-based cohort study used claims data from the Korean National Health Insurance Database, 2014-2020. Two distinct cohorts were established to compare each incretin-based drug with sodium-glucose cotransporter-2 (SGLT2) inhibitors, chosen as active comparators because of their previous non-association with thyroid cancer, and their common usage as add-on therapy to metformin along with GLP-1RAs and DPP-4 inhibitors. The first cohort included 21 722 new users of GLP-1RAs and 326 993 new users of SGLT2 inhibitors, whereas the second cohort included 904 300 DPP-4 inhibitor new users and 112 017 SGLT2 inhibitor new users. The outcome was the time to incident thyroid cancer. Weighted Cox proportional models were used to estimate hazard ratios of thyroid cancer incidence associated with incretin-based drugs of interest. RESULTS: The use of GLP-1RAs was not associated with an increased risk of thyroid cancer (weighted hazard ratio 0.98, 95% confidence interval 0.62-1.53) compared with that of SGLT2 inhibitors. Using DPP-4 inhibitors was also not associated with an increased risk of thyroid cancer (0.95, 0.79-1.14) compared with that of SGLT2 inhibitors. No significant effect modifications were observed across subgroup analyses. Sensitivity analyses, including alternative outcome definition analysis of medullary thyroid cancer, were consistent with the primary analysis results. CONCLUSIONS: GLP-1RAs and DPP-4 inhibitors were not associated with an increased risk of thyroid cancer in individuals with type 2 diabetes.

Reconstruction Using a Scrotal Flap with Autologous Augmentation for Delayed Infection Caused by Penile Filler Injection: A Case Report.

Penile augmentation using filler injections is gaining popularity; however, complications such as foreign body reactions can arise, leading to issues like penile ulceration and necrosis, subsequently necessitating reconstruction. The existing method of the reconstruction of the penis is primarily aimed at filling the deficit. In this paper, we describe a case in which a scrotal flap and autologous augmentation were utilized to treat a soft tissue defect caused by a delayed infection following a penile filler injection. The patient, a 41-year-old male, had received an Aquafilling® (Biomedica, Prague, Czech Republic) filler injection seven years earlier and later developed a delayed infection. After debridement, the penile defect spanned the entire shaft, and the circumference of the flaccid penis was 7.5 cm. Using a bilateral scrotal flap technique, the lower margins of both flaps were rolled inward after de-epithelialization to achieve autologous augmentation. Over the three-month post-surgery follow-up, neither infections nor flap necrosis were observed. The penile circumference increased to 12 cm, and the patient reported high satisfaction with the outcome. This new surgical technique can be widely applied as treatment for a variety of penile defects.

PNPLA3 genotypes modify the adverse effect of the total energy intake on high-risk nonalcoholic steatohepatitis development.

BACKGROUND: The relationship between diet and risk genotypes in nonalcoholic steatohepatitis (NASH) development and fibrosis progression in patients with nonalcoholic fatty liver disease (NAFLD) remains unclear. OBJECTIVE: We aimed to investigate the effects of diet on NASH development and fibrosis progression in patients with NAFLD stratified by the PNPLA3 genotype. METHODS: We performed a prospective study in a cohort of patients with biopsy-confirmed NAFLD. Histologic deterioration was obtained using serial transient elastography at every 1 or 2 y. The primary outcome was fibrosis progression, and the secondary outcome was development of high-risk NASH, defined as FibroScan-aspartate aminotransferase score ≥0.67 during the follow-up of patients with nonalcoholic fatty liver at the baseline. Dietary intake was evaluated using a semiquantitative food frequency questionnaire. RESULTS: The primary outcome was observed in 42 (29.0%) of the 145 patients during a median follow-up of 49 mo; neither the total energy intake nor each macronutrient intake significantly affected the primary outcome occurrence. Conversely, the total energy intake (HR per 1-SD: 3.03; 95% CI: 1.31, 7.01) and the PNPLA3 rs738409 genotype [HR per 1 risk allele (G): 2.06; 95% CI: 1.11, 3.83)] were independent risk factors for high-risk NASH. The significant interaction between the total energy intake and PNPLA3 genotype was noted in developing high-risk NASH (P = 0.044). As the number of PNPLA3 risk alleles decreased, the effect of the total energy intake on high-risk NASH increased; the HR per 1-SD increment in total energy intake was 1.52 (95% CI: 0.42, 5.42), 3.54 (95% CI: 1.23, 10.18), and 8.27 (95% CI: 1.20, 57.23) for the GG, CG, and CC genotypes, respectively. CONCLUSIONS: The total energy intake adversely affected the development of high-risk NASH in patients with biopsy-confirmed NAFLD. The effect was more prominent in patients without the PNPLA3 risk allele, highlighting the importance of personalized dietary interventions in NAFLD treatment.

Analysis of thromboembolic events in patients with non-small cell lung cancer who received adjuvant chemotherapy: single-center real-world data.

Thromboembolic events (TEEs) are common in cancer patients, with increased risk of TEE by chemotherapy in patients with lung cancer. However, TEEs in patients with non-small cell lung cancer (NSCLC) who received adjuvant chemotherapy have rarely been reported. This study retrospectively analyzed real-world data of 275 patients with NSCLC treated with adjuvant chemotherapy after surgery from October, 2005 to June, 2020, in a single institution. The incidence of TEEs during or within one year of completion of adjuvant chemotherapy was investigated, and factors related to TEEs were analyzed. TEEs were confirmed in nine patients (3.3%), without fatal event related to TEEs. None of the factors, including Khorana score, was significantly associated with the occurrence of TEEs. All patients with TEEs had pathologic stage IIB or higher and a history of smoking, except for one patient. In conclusion, TEEs occurred in a smaller proportion of patients with NSCLC treated with adjuvant chemotherapy in the real world compared with those treated with palliative chemotherapy in previous reports. Furthermore, prophylactic anticoagulation in patients with NSCLC receiving adjuvant chemotherapy may not be needed except for high-risk patients, although those patients should be informed about the possible risk of TEEs.
