Background: Increased 30-day mortality rates have been reported in patients undergoing elective surgery later compared with earlier in the week. However, these reports have been conflicting for esophageal surgery. We conducted a study to assess the differences in outcomes of patients undergoing surgery for esophageal cancer earlier in the week (Tuesday) versus later (Friday).

Methods: This retrospective analysis of a prospectively maintained database included patients with esophageal cancer who underwent esophageal resection in a tertiary cancer center between 1 January 2005 and 31 December 2017. We compared patients operated on Tuesdays versus Fridays. The primary outcome was a composite of major morbidity (defined as Clavien-Dindo grade 3 or more) and/or mortality. Secondary outcomes included duration of post-operative ventilation, and length of ICU and hospital stay.

Results: Among 1300 patients included, 733 were operated on a Tuesday and 567 on a Friday. Patient and surgery characteristics were similar in the two groups. The primary outcome (composite of major morbidity and mortality) was 23.6% in the Tuesday group versus 26.3% in the Friday group. Mortality was similar in the two groups (6.0%). Multivariable logistic regression analysis showed that the day of surgery was not a predictor of major morbidity or mortality.

Conclusions: In patients undergoing esophagectomy at tertiary care high volume cancer center, there was no difference in major morbidity and mortality whether the surgery was performed early in the week (Tuesday) or closer to the weekend (Friday).

Methods: Transmasculine persons (N = 590) aged 18 years and above from 57 countries completed a brief online survey from April to July 2022 about sexual behavior, knowledge, and interest in PrEP, current access to PrEP and gender-affirmative care, and preferred context for accessing PrEP. Descriptive analyses were stratified by country income group.

Objectives: To determine the prevalence of self-reported delayed adverse events (DAEs), major AEs, and flares following COVID-19 vaccinations among patients with autoimmune rheumatic diseases (AIRDs) in Malaysia.

Methodology: An electronically validated survey from the COVID-19 vaccination in autoimmune diseases (COVAD) study group was distributed in July 2021 to patients with autoimmune diseases and healthy controls (HCs). The survey collected data on DAEs (any AE that persisted or occurred after 7 days of vaccination), any early or delayed major adverse events (MAEs), and flares following COVID-19 vaccination.

Background: Esophageal atresia is one of the most common life-threatening congenital malformations and is defined as an interruption in the continuity of the esophagus with or without fistula to the trachea or bronchi. Definitive treatment is surgical ligation of the fistula if present and esophageal end-to-end anastomosis of the two pouches, thereby reconstructing the continuity of the esophagus. During this procedure, the surgeon may choose to either ligate or preserve the azygos vein, a major draining vein for the esophagus and surrounding structures, but no definitive consensus on the matter exists.
