Background Combining left atrial appendage closure with catheter ablation (LAACCA) has been proposed as a potential approach to improving outcomes by simultaneously addressing arrhythmia and reducing stroke risk. This study compares the in-hospital outcomes of LAACCA vs. catheter ablation (CA) alone for atrial fibrillation (AFib) in patients with heart failure with reduced ejection fraction (HFrEF). Methods We analyzed adult hospitalizations with HFrEF and AFib who underwent LAACCA or CA alone from the 2016-2020 nationwide inpatient sample using validated ICD-10 codes. Propensity score matching, accounting for patient-, hospital-, and procedure-level covariates, illness severity, and baseline risk of mortality, was used to alleviate bias in nonrandomized treatment assignments. The primary endpoints included all-cause in-hospital mortality, hospital stay, and hospitalization costs. Secondary endpoints included postprocedural complication rates. Prolonged hospitalization was defined as hospital stay in the top decile of hospital stay in each cohort. All statistical analyses in the study were based on weighted hospital data. Results About 233,865 HFrEF patients were hospitalized for AFib. Approximately 27,945 (11.9%) underwent LAACCA, while 205,920 (88.1%) underwent CA only. The cohort comprised mostly males (151,077; 64.6%) (mean age: 67.4; SD: 4.3). The propensity score-matched cohort comprised 18,195 LAACCAs and 18,195 CAs; all covariate imbalances were alleviated. LAACCA was associated with a higher rate of prolonged hospital stay (7.6 vs 5.6 days; P<0.001), a higher mortality rate (209 (1.1%) vs. 160 (0.9%); P=0.011), and higher mean hospital costs ($289,960 vs. $183,932; P<0.001) compared with CA alone. LAACCA was associated with a higher incidence of acute myocardial ischemia (528 (2.9%) vs. 455 (2.5%); P=0.013), complete atrioventricular block (1,200 (6.6%) vs. 892 (4.9%); P=0.004), need for implantable device therapy (1,510 (8.3%) vs. 1,348 (7.4%); P=0.017), pneumothorax (328 (1.8%) vs. 91 (0.5%); P<0.0001), hemothorax (200 (1.1%) vs. 127 (0.7%); P<0.0001), pneumonia (983 (5.4%) vs. 546 (3.0%); P<0.0001), vascular access complications (346 (1.9%) vs. 255 (1.4%); P=0.046), and septicemia (309 (1.7%) vs. 182 (1.0%); P<0.001). CA was associated with a greater incidence of cardiac tamponade (237 (1.3%) vs. 382 (2.1%); P=0.010) and femoral artery pseudoaneurysm (364 (0.2%) vs. 91 (0.5%); P<0.001). Conclusion LAACCA was correlated with higher mortality odds compared to CA alone for atrial fibrillation in HFrEF.

Tumour necrosis factor-alpha (TNF-α) inhibitors are commonly used in the treatment of ankylosing spondylitis (AS) due to their effectiveness in reducing inflammation and slowing disease progression. However, their use is associated with an increased risk of opportunistic infections, particularly tuberculosis (TB). This case report presents a young male patient in the United Kingdom (UK) with AS, who had been on long-term biological therapy with adalimumab, a TNF-α inhibitor. The patient developed disseminated TB, which rapidly progressed and unfortunately resulted in the patient's death. This case underscores the importance of comprehensive screening for latent TB before initiating TNF-α inhibitor therapy, as well as ongoing monitoring throughout treatment. Given the multicultural nature of the UK, where individuals may be exposed to TB without traveling to endemic areas, careful attention to TB risk across all ethnicities is critical. This case highlights the need for heightened vigilance and tailored preventive strategies to mitigate the risks of TNF-α therapy.

The incidence of melanoma is increasing. We ascertained perceptions regarding sunscreen and factors influencing choice in patients with melanoma. A survey was distributed to all members of a support group for people with melanoma. In total, 571 responses were received across 6 weeks. Most respondents (n = 452/571; 79.2%) indicated that they knew how much sunscreen to apply; the most popular frequency of application was once daily (n = 180/571; 31.5%). The most popular cosmetic benefit respondents indicated was reduced redness on sun-exposed areas of the skin (n = 418/571; 73.2%). Most respondents (n = 552/571; 96.7%) agreed that more education is needed regarding the importance of wearing sunscreen. The three most popular factors influencing sunscreen choice were a sun protection factor (SPF) > 50 (n = 299/571; 52.4%), dermatologist recommendation (n = 267/571; 46.8%) and price (n = 262/571; 45.9). Sustainable packaging (n = 45/571; 7.9%) and ethical sourcing of ingredients (n = 65/571; 11.4%) were not ranked highly. Given that 42.0% (n = 240/571) only applied sunscreen on sunny days, an education campaign is required. Industry should consider public education regarding sustainability. A further study ascertaining the views and perceptions of sunscreen in a cohort of people without melanoma is strongly encouraged.

Metformin is an established staple drug in the management of Type 2 diabetes mellitus. In this systematic review, we sought to establish the clinical utility of metformin in a range of dermatological conditions. The pathophysiology of acne vulgaris and polycystic ovarian syndrome (PCOS) is well suited to the pharmacological profile of metformin, and we found evidence for its efficacy in managing these conditions. We found some evidence for the use of metformin particularly in acne and PCOS; however, the evidence base is of mixed quality. There is scope for clinicians to consider metformin as an adjunct therapy in acne and PCOS. There is generally insufficient evidence to recommend metformin in other dermatological conditions.
