RESUMO

BACKGROUND: Lorcaserin, a selective serotonin 2C receptor agonist that modulates appetite, has proven efficacy for weight management in overweight or obese patients. The cardiovascular safety and efficacy of lorcaserin are undefined. METHODS: We randomly assigned 12,000 overweight or obese patients with atherosclerotic cardiovascular disease or multiple cardiovascular risk factors to receive either lorcaserin (10 mg twice daily) or placebo. The primary safety outcome of major cardiovascular events (a composite of cardiovascular death, myocardial infarction, or stroke) was assessed at an interim analysis to exclude a noninferiority boundary of 1.4. If noninferiority was met, the primary cardiovascular efficacy outcome (a composite of major cardiovascular events, heart failure, hospitalization for unstable angina, or coronary revascularization [extended major cardiovascular events]) was assessed for superiority at the end of the trial. RESULTS: At 1 year, weight loss of at least 5% had occurred in 1986 of 5135 patients (38.7%) in the lorcaserin group and in 883 of 5083 (17.4%) in the placebo group (odds ratio, 3.01; 95% confidence interval [CI], 2.74 to 3.30; P<0.001). Patients in the lorcaserin group had slightly better values with respect to cardiac risk factors (including blood pressure, heart rate, glycemic control, and lipids) than those in the placebo group. During a median follow-up of 3.3 years, the rate of the primary safety outcome was 2.0% per year in the lorcaserin group and 2.1% per year in the placebo group (hazard ratio, 0.99; 95% CI, 0.85 to 1.14; P<0.001 for noninferiority); the rate of extended major cardiovascular events was 4.1% per year and 4.2% per year, respectively (hazard ratio, 0.97; 95% CI, 0.87 to 1.07; P=0.55). Adverse events of special interest were uncommon, and the rates were generally similar in the two groups, except for a higher number of patients with serious hypoglycemia in the lorcaserin group (13 vs. 4, P=0.04). CONCLUSIONS: In a high-risk population of overweight or obese patients, lorcaserin facilitated sustained weight loss without a higher rate of major cardiovascular events than that with placebo.

RESUMO

BACKGROUND: Cervix cancer is a significant health problem. As access to quality care in Small Island Developing States improves, and cancer centers become established, providers of care can summarize local experience to benchmark system quality and look for ways to further improve value. METHODS: This is a retrospective study of all cases of cervix cancer managed 2006-2016 at The Cancer Centre Bahamas, in conjunction with Princess Margaret Hospital, Nassau, affiliated with The University of West Indies. Seventy-two women received curative radiotherapy or chemoradiotherapy. Herein are reported presenting characteristics, treatments, waiting and overall treatment times, plus outcomes of recurrence, survival, and adverse events. RESULTS: For 68 newly diagnosed cases, median waiting time (diagnosis to commencing treatment) was 110 days. It was 90 days for those 47 cases who had no prior surgery or neoadjuvant chemotherapy. Overall, 99% of intended external radiotherapy fractions, 74% of brachytherapy sessions, and 79% of concurrent weekly chemotherapy were administered. For all 72 cases, median overall treatment time was 63 days; and for the 47 case sub-group, it was 78 days during 2006-2010 and 65 days during 2011-2016 (p = 0.005), so improving over calendar time. Four cases experienced grade 3-4 toxicities. Twelve had urological complications from disease or treatment. Five cases experienced local failure; eight experienced distant failure. Newly diagnosed stage 2B (26/72) had a 2-year survival of 71%. CONCLUSION: This report demonstrates the impact of providing curative radiation-based treatments for cervical cancer in a small state. It suggests ways to further improve operations and justifies additional research.

RESUMO

PURPOSE: This is a first report from The Bahamas of management and long-term outcomes in men with non-metastatic prostate cancer treated with radiotherapy, with or without androgen deprivation therapy, from 2004 to 2016. METHODS: Patients were characterized by baseline factors, stratified by risk groups using tumor stage (clinical T-stage), prostate-specific antigen (PSA) test result and Gleason grade, and sorted by treatment combinations (by radiation volume and use of androgen deprivation). RESULTS: Overall, 205/216 men were Afro-Caribbean. Median age was 66. There were 18 low-, 77 intermediate-, and 121 high-risk patients, treated with prostate-only versus pelvis plus prostate radiotherapy, many receiving 2 years of androgen suppression. Time to commence radiation was about 6 months from initial diagnosis. In those not relapsing, global PSA nadir was reached in 4 years and was under 1.0, reduced from a mean at baseline of 31. At 10 years, disease-free experience (32 relapses) was 68% and overall survival was 87%, although only 2/12 deaths were related to prostate cancer. This experience compares favorably with recently published outcomes from other countries using very similar treatments. CONCLUSIONS: This study establishes benchmark statistics from diagnosis to long-term follow-up. Outcomes in Bahamian men are consistent with expectations from risk-stratified guidelines followed in developed countries.

RESUMO

Dynamic cardiomyoplasty was performed in a patient using a new cardio-myostimulator (LD-PACE II) designed to enable a novel stimulation regimen that utilizes a new range of stimulation options, including cessation during sleep. After treatment, left ventricular ejection fraction improved in 24 months from 15% to 25% and New York Heart Association classification improved from class IV to II.
