Efficacy of topical treatments for mild-to-moderate acne: A systematic review and meta-analysis of randomized control trials.

Acne is a common skin condition, but little data exist on the comparative efficacy of topical acne therapies. We conducted a systematic review and network meta-analysis to evaluate the efficacy of topical therapies for mild-to-moderate acne. Searches in PubMed/MEDLINE, Cochrane CENTRAL via Ovid, Embase via Ovid and Web of Science were conducted on 29 November 2021. Randomized controlled trials examining ≥12 weeks of topical treatments for acne vulgaris in subjects aged 12 and older were included. Main outcomes were absolute or percent change in acne lesion count and treatment success on the Investigator's Global Assessment scale. Thirty-five randomized clinical trials with 33,472 participants comparing nine different topical agents were included. Adapalene-benzoyl peroxide (BPO), clindamycin-BPO and clindamycin-tretinoin demonstrated the greatest reduction in non-inflammatory (ratio of means [RoM] 1.76; 95% CI [1.46; 2.12], RoM 1.70; 95% CI [1.44; 2.02] and RoM 1.87; 95% CI [1.53; 2.30], respectively), inflammatory (RoM 1.56; 95% CI [1.44; 1.70], RoM 1.49; 95% CI [1.39; 1.60] and RoM 1.48; 95% CI [1.36; 1.61], respectively) and total lesion count (ROM 1.67; 95% CI [1.47; 1.90], RoM 1.59; 95% CI [1.42; 1.79] and RoM 1.64; 95% CI [1.42; 1.89], respectively) compared to placebo. All single agents outperformed placebo except tazarotene, which did not significantly outperform placebo for inflammatory and non-inflammatory lesion count reduction. Most combination agents significantly outperformed their individual components in lesion count reduction and global assessment scores, except for clindamycin-tretinoin and clindamycin-BPO, which did not significantly outperform tretinoin (RoM 1.13; 95% CI [0.94; 1.36]) and BPO (RoM = 1.15, 95% CI [0.98; 1.36]), respectively, for non-inflammatory lesion reduction. There was no significant difference amongst most single agents when evaluating lesion count reduction. Combination agents are generally most effective for mild-to-moderate acne; however for non-inflammatory acne, the addition of clindamycin in topical regimens is unnecessary and should be avoided.

Intraoperative Use of Intra-Aortic Balloon Pump to Generate Pulsatile Flow During Heart Transplantation: A Single-Center Experience.

The physiologic impact of pulsatile flow (PF) on end-organ perfusion during cardiopulmonary bypass (CPB) is controversial. Using an intra-aortic balloon pump (IABP) to maintain PF during CPB for patients undergoing heart transplantation (HT) may impact end-organ perfusion, with implications for postoperative outcomes. A single-center retrospective study of 76 patients bridged to HT with IABP was conducted between January 2018 and December 2022. Beginning in May 2022, patients received IABP-generated PF during CPB at an internal rate of 80 beats/minute. Fifty-eight patients underwent HT with the IABP turned off (IABP-Off), whereas 18 patients underwent HT with IABP-generated PF (IABP-On). The unmatched IABP-On group experienced shorter organ ischemia times (180 vs . 203 minutes, p = 0.015) and CPB times (104 vs . 116 minutes, p = 0.022). The cohort was propensity matched according to age, organ ischemia time, and CPB time. Elevations in postoperative lactates in the immediate (2.8 vs . 1.5, p = 0.062) and 24 hour (4.7 vs . 2.4, p = 0.084) postoperative periods trended toward significance in the matched IABP-Off group. There was no difference in postoperative vasoactive inotropic score (VIS), postoperative creatinine, or length of stay. This limited preliminary data suggest that maintaining counterpulsation to generate PF during CPB may improve end-organ perfusion in this patient population as suggested by lower postoperative lactate levels.

Adaptation, Implementation, and Evaluation of a Public Health Research Methods Training for Youth.

Purpose: To adapt, implement, and evaluate a public health research methods training program for youth. The Community Research Fellows Training Program is an evidence-based public health research methods training program for adults (18 years and older). The Youth Research Fellows Training (YRFT) is an adaptation of this program for youth. Methods: University faculty facilitate didactic training sessions and experiential small group activities in biweekly sessions conducted as part of an existing 4-week summer camp. Participants were African American girls (n=11) ranging from ages 10 to 14 years (most recent grade completed 4th-8th). To evaluate participant knowledge gain and satisfaction pre-tests were administered before each session, and post-test and evaluations were administered after each session. In addition, faculty completed web-based evaluation surveys on their experience teaching in the program. Results: Mean and median post-test scores were higher than pre-test scores for most (6 of the 7) of the training sessions; one session had no difference in scores. Participants rated the sessions well, on average overall session ratings of 4.3-4.8 on a 5-point Likert scale. Faculty rated their experience teaching in the program as excellent or very good and would be willing to teach in the program again (n=7; 100%). Conclusion: This pilot implementation of the YRFT program proved highly successful in terms of participant and faculty experience. The program evaluation demonstrates increased knowledge of public health research methods. This program has the potential to prepare youth to engage in public health research as partners not just participants.
