Pulse Methylprednisolone Versus Dexamethasone in COVID-19: A Multicenter Cohort Study

IMPORTANCE:. Although pulse (high-dose) methylprednisolone therapy can hypothetically control immune system flare-ups effectively, the clinical benefit of pulse methylprednisolone compared with dexamethasone in COVID-19 remains inconclusive. OBJECTIVES:. To compare pulse methylprednisolone to dexamethasone as a COVID-19 treatment. DESIGN, SETTING, AND PARTICIPANTS:. Using a Japanese multicenter database, we identified adult patients admitted for COVID-19 and discharged between January 2020 and December 2021 treated with pulse methylprednisolone (250, 500, or 1,000 mg/d) or IV dexamethasone (≥ 6 mg/d) at admission day 0 or 1. Main Outcomes and Measures:. The primary outcome was in-hospital mortality. Secondary outcomes were 30-day mortality, new ICU admission, insulin initiation, fungal infection, and readmission. Multivariable logistic regression was conducted to differentiate the dose of pulse methylprednisolone (250, 500, or 1,000 mg/d). Additionally, subgroup analyses by characteristics such as the need for invasive mechanical ventilation (IMV) were also conducted. RESULTS:. A total of 7,519, 197, 399, and 1,046 patients received dexamethasone, 250, 500, and 1,000 mg/d of methylprednisolone, respectively. The crude in-hospital mortality was 9.3% (702/7,519), 8.6% (17/197), 17.0% (68/399), and 16.2% (169/1,046) for the different doses, respectively. The adjusted odds ratio (95% CI) was 1.26 (0.69–2.29), 1.48 (1.07–2.04), and 1.75 (1.40–2.19) in patients starting 250, 500, and 1,000 mg/d of methylprednisolone, respectively, compared with those starting dexamethasone. In subgroup analyses, the adjusted odds ratio of in-hospital mortality was 0.78 (0.25–2.47), 1.12 (0.55–2.27), and 1.04 (0.68–1.57) in 250, 500, and 1,000 mg/d of methylprednisolone, respectively, among patients with IMV, whereas the adjusted odds ratio was 1.54 (0.77–3.08), 1.62 (1.13–2.34), and 2.14 (1.64–2.80) among patients without IMV. CONCLUSIONS AND RELEVANCE:. Higher doses of pulse methylprednisolone (500 or 1,000 mg/d) may be associated with worse COVID-19 outcomes when compared with dexamethasone, especially in patients not on IMV

Impact of Endoscopic Surgical Skill Qualification on Laparoscopic Resections for Rectal Cancer in Japan: The EnSSURE Study

Objective:. This cohort study investigated short- and long-term postoperative outcomes of laparoscopic procedures for rectal cancer performed with versus without certified surgeons. Background:. In Japan, the Endoscopic Surgical Skill Qualification System (ESSQS) evaluates surgical skills deemed essential for laparoscopic surgery; however, it is unknown whether this certification contributes to procedural safety. Methods:. Outcomes of laparoscopic rectal resections for cStage II and III rectal cancer performed from 2014 to 2016 at 56 Japanese hospitals were retrospectively reviewed. The impact of having versus not having certified surgeons on postoperative complications and other short- and long-term outcomes were assessed. In cases with ESSQS-certified surgeons, surgeons attended surgery in the capacity of an operator, assistant, scope operator, or advisor. Results:. Overall, 3188 procedures were analyzed, with 2644 procedures performed with and 544 without ESSQS-certified surgeons. A multivariate logistic regression model showed that the adjusted odds ratio of postoperative complications after procedures performed with ESSQS-certified surgeons was 0.68 (95% confidence interval, 0.51–0.91; P = 0.009). The adjusted odds ratios for conversion and pathological R0 resection rates with ESSQS-certified surgeons were 0.20 (P < 0.001) and 2.10 (P = 0.04), respectively. Multiple linear regression analyses showed significantly shorter surgical duration and more harvested lymph nodes for operations performed with ESSQS-certified surgeons. Multivariate Cox regression showed that the adjusted hazard ratios for poor overall and recurrence-free survival after operations performed with ESSQS-certified surgeons were 0.88 (P = 0.35) and 1.04 (P = 0.71), respectively. Conclusions:. This study showed the superiority of the short-term postoperative results for laparoscopic rectal procedures performed with ESSQS-certified surgeons
