The association of tadalafil exposure with lower rates of major adverse cardiovascular events and mortality in a general population of men with erectile dysfunction.

BACKGROUND: Tadalafil is a long-acting phosphodiesterase-5 inhibitor (PDE-5i) indicated for erectile dysfunction (ED). HYPOTHESIS: Our hypothesis was that tadalafil will reduce the risk of major adverse cardiovascular events (MACE: composite of cardiovascular death, myocardial infarction, coronary revascularization, unstable angina, heart failure, stroke) and all-cause death in men with ED. METHODS: A retrospective observational cohort study was conducted in a large US commercial insurance claims database in men with a diagnosis of ED without prior MACE within 1 year. The exposed group (n = 8156) had ≥1 claim for tadalafil; the unexposed group (n = 21 012) had no claims for any PDE-5i. RESULTS: Primary outcome was MACE; secondary outcome was all-cause death. Groups were matched for cardiovascular risk factors, including preventive therapy. Over a mean follow-up of 37 months for the exposed group and 29 months for the unexposed group, adjusted rates of MACE were 19% lower in men exposed to tadalafil versus those unexposed to any PDE-5i (hazard ratio [HR] = 0.81; 95% confidence intervals [CI] = 0.70-0.94; p = .007). Tadalafil exposure was associated with lower adjusted rates of coronary revascularization (HR = 0.69; 95% CI = 0.52-0.90; p = .006); unstable angina (HR = 0.55; 95% CI = 0.37-0.81; p = .003); and cardiovascular-related mortality (HR = 0.45; CI = 0.22-0.93; p = .032). Overall mortality rate was 44% lower in men exposed to tadalafil (HR = 0.56; CI = 0.43-0.74; p < .001). Men in the highest quartile of tadalafil exposure had the lowest rates of MACE (HR: 0.40; 95% CI: 0.28-0.58; p < .001) compared to lowest exposure quartile. CONCLUSION: In men with ED, exposure to tadalafil was associated with significant and clinically meaningful lower rates of MACE and overall mortality.

Survival Outcomes of Temporal Bone Squamous Cell Carcinoma: A Systematic Review and Meta-Analysis.

OBJECTIVE: Temporal bone squamous cell carcinoma (TBSCC) is a rare malignancy with poor prognosis, and optimal treatment for advanced cases is uncertain. Our systematic literature review aimed to assess 5-year survival outcomes for advanced TBSCC across different treatment modalities. DATA SOURCES: EMBASE, Medline, PubMed, and Web of Science. REVIEW METHODS: A systematic literature review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines for articles published between January 1989 and June 2023. RESULTS: The review yielded 1229 citations of which 31 provided 5-year survival data for TBSCC. The final analysis included 1289 patients. T classification data was available for 1269 patients and overall stage for 1033 patients. Data for 5-year overall survival (OS) was 59.6%. Five-year OS was 81.9% for T1/2 and 47.5% for T3/4 (P < .0001). OS for T1/T2 cancers did not significantly differ between surgery and radiation (100% vs 81.3%, P = .103). For advanced-stage disease (T3/T4), there was no statistical difference in OS when comparing surgery with postoperative chemoradiotherapy (CRT) (OS 50.0%) versus surgery with postoperative radiotherapy (XRT) (OS 53.3%) versus definitive CRT (OS 58.1%, P = .767-1.000). There was not enough data to assess the role of neoadjuvant CRT. CONCLUSION: Most patients will present with advanced-stage disease, and nodal metastasis is seen in nearly 22% of patients. This study confirms the prognostic correlation of the current T classification system. Our results suggest that OS did not differ significantly between surgery and XRT for early stage disease, and combined treatment modalities yield similar 5-year OS for advanced cancers.
