Introduction To examine within-class sulfonylurea safety, we compared risks of major adverse cardiovascular events (MACE) and severe hypoglycemia among adults with type 2 diabetes (T2D) and moderate cardiovascular risk following sulfonylurea initiation. Research design and methods We conducted a target trial emulation including adults ≥21 years old with T2D and moderate cardiovascular risk who initiated glimepiride, glipizide or glyburide between 2014 and 2021, using claims data from Optum Labs Data Warehouse and the Medicare fee-for-service 100% sample. Study outcomes were MACE (primary), expanded MACE and its components and emergency department or hospital encounters for hypoglycemia, ascertained during follow-up through 2022. Inverse probability of treatment weighting (IPTW) was applied using propensity scores estimated using the super learner ensemble, and outcomes were examined using IPTW Cox proportional hazards models. Results The weighted study cohort comprised 314 699 patients (mean age 66.9 years, 52.0% men, 76.6% non-Hispanic white). At 1 year, MACE was experienced by 2.5%, 2.7% and 2.8% of patients starting glimepiride, glipizide and glyburide, respectively. Compared with glimepiride, glyburide and glipizide were associated with higher risk of MACE (HR 1.10, 95% CI 1.05 to 1.16 for glyburide; HR 1.05, 95% CI 1.03 to 1.07 for glipizide). At 1 year, severe hypoglycemia was experienced by 0.3%, 0.3% and 0.4% of patients starting glimepiride, glipizide and glyburide, respectively. Glyburide was associated with a greater risk of severe hypoglycemia compared with glipizide (HR 1.43, 95% CI 1.23 to 1.65), while glipizide was associated with a lower risk compared with glimepiride (HR 0.82, 95% CI 0.77 to 0.87). Conclusions Among adults with T2D and moderate cardiovascular risk, glimepiride was associated with lowest risk of MACE and glipizide with lowest risk of severe hypoglycemia. These results can help inform treatment selection if sulfonylureas are used for glucose-lowering.

Importance Total thyroidectomy is the established surgical standard for hereditary and sporadic medullary thyroid cancer (sMTC). However, for unilateral sporadic tumors, its benefit over lobectomy remains uncertain. Objective To compare oncologic outcomes between total thyroidectomy and lobectomy in patients with sMTC. Data Sources and Study Selection MEDLINE, Embase, Scopus, and Cochrane Central Register of Controlled Trials were searched from inception to December 2025 to identify comparative studies on patients with sMTC who underwent total thyroidectomy or lobectomy. Data Extraction and Synthesis Reviewers working independently and in duplicate screened titles, abstracts, and full-text articles for eligibility using standardized instructions. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses ( PRISMA ) and Meta-Analysis of Observational Studies in Epidemiology ( MOOSE ) guidelines were used for reporting. Main Outcomes and Measures Primary outcomes were mortality, overall survival, structural recurrence, biochemical cure, and distant metastasis development. The secondary outcome was postoperative complications. Effect measures were calculated as odds ratios (ORs) or relative risks (RRs) with 95% CIs using a random-effects model. The risk of bias was assessed using the Newcastle-Ottawa Scale. Results Nine retrospective studies met inclusion criteria and comprised 1371 patients (295 of 397 patients [74.3%] with documented sex were female, and median age ranged from 45.0 to 58.2 years). A total of 531 patients (38.7%) underwent lobectomy and 840 (61.3%) underwent total thyroidectomy. Of 341 tumors, 280 (82.1%) lacked extrathyroidal extension, 284 of 401 tumors (70.8%) measured smaller than 2 cm (70.8%), and 197 of 343 tumors (57.4%) were node negative; central neck dissection was performed in 445 of 492 patients (90.4%). Multifocal disease was uncommon and reported in 30 of 330 patients (9.1%). Mortality did not differ at 5 years (RR, 0.30; 95% CI, 0.07-1.35) or beyond (RR, 1.00; 95% CI, 0.40-2.47). Overall survival at 5 years was similar (RR, 1.02; 95% CI, 0.94-1.11). Total thyroidectomy was not associated with lower structural recurrence rates at 5 years (OR, 0.45; 95% CI, 0.14-1.49), but it was associated beyond 5 years (OR, 7.26; 95% CI, 1.07-49.21). No differences were observed for biochemical cure at 5 years (OR, 0.86; 95% CI, 0.47-1.56) or beyond 5 years (OR, 0.87; 95% CI, 0.26-2.89). Distant metastasis development did not differ at 5 years (OR, 1.64; 95% CI, 0.09-31.52). Sensitivity analyses revealed no differences across any outcomes. Postoperative complications were more common in total thyroidectomy. Risk of bias was high in 4 studies, moderate in 4, and low in 1. Conclusions and Relevance Findings in this systematic review and meta-analysis, based on data from retrospective studies, suggest that thyroid lobectomy may be associated with oncologic outcomes comparable to total thyroidectomy in selected patients with sMTC.

BACKGROUND: Pectus deformities are common chest wall abnormalities, with surgical correction recommended for severe cases. Female patients undergoing repair may have a history of breast implants or seek concurrent augmentation. This retrospective study examines clinical implications of pectus repair in patients with breast implants and provides recommendations. STUDY DESIGN: A retrospective review of female patients undergoing pectus repair at Mayo Clinic Arizona (January 1, 2010 to February 1, 2025) was conducted. Outcomes and complications were analyzed in patients with and without breast implants. RESULTS: In total, 456 female patients were included (447 excavatum, 7 arcuatum, and 2 carinatum; median age 32.7). Most patients (78.5%) underwent primary minimally invasive repairs (MIRPE); 6.6% underwent primary hybrid MIRPE, 5.5% underwent redo MIRPE, and 9.4% underwent primary redo open and complex reconstructions. In total, 104 patients (22.8%) had a history of breast implants, with 68 patients having breast implant-related procedures at the time of pectus surgery. At 12 months, the cumulative incidence of infection was significantly higher in patients with implants present at the time of pectus repair than in those without (8.8% vs 1.8%; log rank, p = 0.0015). A 4.9-fold increase in overall infection was seen in patients with indwelling or placed implants during pectus surgery. Deep infections were significantly more common in patients with implants (4.4%) than without (1.0%; p = 0.035). Similarly, superficial infections were more frequent in patients with implants (4.4%) than without (0.8%; p = 0.016). At 30 days, patients with implants had higher rates of infection (p = 0.032), pneumothorax (p = 0.008), and hematoma (p = 0.027), with no significant differences in other complications. CONCLUSIONS: Breast implants at the time of pectus repair were associated with increased risk of postoperative infection, pneumothorax, and hematoma. Removal of implants before pectus repair is recommended with delayed replacement, if desired.

The systemic impairment that accompanies liver cirrhosis is known to carry a significant burden on death and postoperative complications in cardiovascular interventions. This review analyzes the impact of liver cirrhosis on short‐ and long‐term outcomes after cardiac surgery and percutaneous procedures, providing an evidence‐based guidance in the decision‐making process and perioperative management of these patients. Several parameters should be considered by the heart teams when assessing eligibility, indications for intervention, and perioperative management of these patients. Life expectancy, long‐term procedural outcomes, Child–Pugh or the Model for End‐Stage Liver Disease score, presence of gastroesophageal varices and hepatic venous pressure gradient were extrapolated as the main determinants in decision making in patients with cirrhosis. Assessment and treatment of gastroesophageal varices is mandatory. Hepatic venous pressure gradient values >20 mm Hg preclude patients from a surgical approach. Considering the poor prognosis of advanced liver cirrhosis, futile treatments should be avoided. A multidimensional heart team approach involving surgical, cardiologic, anesthesiologic, hepatological, and medical considerations is recommended.

Abstract Background Precise delineation of non-contrast-enhancing tumor (nCET) in glioblastoma (GB) is critical for maximal safe resection, yet routine imaging cannot reliably separate infiltrative tumor from vasogenic edema. The aim of this study was to develop and validate an automated method to identify peritumoral subregions compatible with nCET and assess its prognostic value. Methods Pre-operative T2-weighted and FLAIR MRI from 940 patients with newly diagnosed GB in four multicenter cohorts were analyzed. A deep-learning model segmented enhancing tumor, edema and necrosis; a non-local, spatially varying finite mixture model was applied to identify edema subregions characterized by relatively lower FLAIR hyperintensity, hypothesized to reflect nCET-related tissue. The ratio of these subregions to total edema volume defined the T2/FLAIR Heterogeneity Index (TFHI). Associations between TFHI and overall survival (OS) were examined with Kaplan–Meier curves and multivariable Cox regression. Results Higher TFHI values stratified patients with shorter OS. In the NCT03439332, TFHI above the optimal threshold was associated with a twofold increased hazard of death (hazard ratio [HR] 2.07, 95 % confidence interval 1.33-3.21; P = .0013) and a reduction in median survival of 98 days. Significant, though smaller, prognostic effects were confirmed in GLIOCAT & BraTS (HR= 1.37; P = .047), OUS (HR = 1.37; P = .0032) and pooled analysis (HR= 1.26; P = .0008). TFHI remained an independent predictor after adjustment for age, extent of resection and MGMT methylation. Conclusions We present a reproducible, server-hosted tool for automated identification of imaging-defined, putative nCET-related peritumoral subregions and TFHI biomarker extraction that enables independent prognostic stratification. This approach provides a quantitative framework for studying peritumoral heterogeneity in GB.
