ABSTRACT Objective This study compared the effects of phentermine‐topiramate‐ER (mid‐dose 7.5/46 mg) versus placebo on weight loss and cardiovascular disease (CVD) risk outcomes when used as an adjunct to a digitally enhanced lifestyle intervention (DELI). Methods We conducted a 12‐month, randomized, double‐blind, placebo‐controlled trial at a single tertiary academic center in the United States (June 2020–June 2022). Eighty participants with obesity (BMI ≥ 30 kg/m 2 ) were enrolled in the DELI program, consisting of in‐person and telehealth modalities, dietary and physical activity goals, and use of a smartphone application integrated with digital devices (Apple Watch and Bluetooth‐enabled weight scale and blood pressure monitor). Participants were randomized 1:1 to receive either phentermine‐topiramate‐ER ( n = 42) or placebo ( n = 38) in addition to the DELI. Results At 3 months, the phentermine‐topiramate group lost a mean of 10.82 kg versus 4.04 kg in the placebo group (mean difference −6.78 kg; p = 0.002). At 12 months, weight loss was 15.32 kg versus 5.85 kg, respectively (mean difference −9.48 kg; p < 0.001). Participants receiving phentermine‐topiramate‐ER experienced a 3.35% reduction in the estimated atherosclerotic CVD risk compared to baseline ( p = 0.004). Conclusions Phentermine‐topiramate‐ER, when combined with a DELI, produced significant and sustained weight loss and reduced CVD risk in adults with obesity.

Background Prior research has established some risk factors for an increased risk of severe disease and mortality from coronavirus disease 2019 (COVID-19). However, the impact of HIV infection on SARS-CoV-2 susceptibility and severity is a significant gap in the literature. In the same way, not many studies across the globe have analyzed the degree of vaccination willingness among people living with HIV/AIDS (PLWHA) and considerations regarding prioritizing this population during vaccination plans, particularly in developing countries. Methods A descriptive-analytical cross-sectional study was conducted. Self-completed electronic surveys directed to PLWHA were performed via Twitter in February 2021, using accounts of HIV activists. Results 460 (87.1%) participants were willing to be vaccinated with any COVID-19 vaccine. The reasons for that were listed as 1) the belief that vaccination prevents both the COVID-19 infection (81.3%) as well as being a spreader (52.2%); 2) having a high occupational risk of becoming infected with COVID-19 (22%); and 3) the belief that they would be at high risk of death because of COVID-19 (21.3%). Only 56 (10.6%) participants expressed hesitancy toward vaccination, and 12 (2.2%) stated they did not want to get vaccinated. Conclusions Our results may support the prioritization of people living with HIV during the implementation of vaccination plans in developing countries. New strategies should be adopted to overcome the hesitancy and unwillingness toward the COVID-19 vaccination, especially in populations with risk factors for severe disease.
