Weight gain during the dolutegravir transition in the African Cohort Study

IntroductionDolutegravir (DTG) has become a preferred component of first‐line antiretroviral therapy (ART) in many settings but may be associated with excess weight gain. We evaluated changes in weight and body mass index (BMI) after switch to single‐tablet tenofovir/lamivudine/dolutegravir (TLD) by people living with HIV (PLWH) in four African countries.MethodsThe African Cohort Study (AFRICOS) prospectively follows adults with and without HIV in Kenya, Uganda, Tanzania and Nigeria. Demographics, ART regimen, weight, BMI and waist‐to‐hip ratio were collected every 6 months. Multivariable Cox proportional hazards modelling was used to estimate hazard ratios and 95% confidence intervals (CIs) for factors associated with developing a BMI ≥25 kg/m². Linear mixed effects models with random effects were used to examine the average change in BMI, weight and waist‐to‐hip ratio.ResultsFrom 23 January 2013 to 1 December 2020, 2950 PLWH were enrolled in AFRICOS and 1474 transitioned to TLD. In adjusted models, PLWH on TLD had 1.77 times the hazard of developing a high BMI (95% CI: 1.22–2.55) compared to PLWH on non‐TLD ART. Examining change in weight among all PLWH on ART, participants on TLD gained an average of 0.68 kg (95% CI: 0.32–1.04) more than PLWH on other regimens after adjusting for duration on ART, sex, age, study site and CD4 nadir. Among participants who switched to TLD, the average change in weight prior to TLD switch was 0.35 kg/year (95% CI: 0.25–0.46) and average change in weight was 1.46 kg/year (95% CI: 1.18–1.75) in the year following transition to TLD after adjustment for confounders.ConclusionsElevated BMI and weight gain among PLWH on TLD are concerning safety signals. Implications for the development of metabolic comorbidities should be monitored, particularly if annual weight gain persists during continued follow‐up after transitioning to TLD.     

Using web‐based training to improve accuracy of blood pressure measurement among health care professionals: A randomized trial

Accurate blood pressure measurement is crucial for proper screening, diagnosis, and monitoring of high blood pressure. However, providers are not aware of proper blood pressure measurement skills, do not master all the appropriate skills, or miss key steps in the process, leading to inconsistent or inaccurate readings. Training in blood pressure measurement for most providers is usually limited to a one‐time brief demonstration during professional education coursework. The American Medical Association and the American Heart Association developed a 30‐minute e‐Learning module designed to refresh and improve existing blood pressure measurement knowledge and clinical skills among practicing providers. One hundred seventy‐seven practicing providers, which included medical assistants, nurses, advanced practice providers, and physicians, participated in a multi‐site randomized educational study designed to assess the effect of this e‐Learning module on blood pressure measurement knowledge and skills. Participants were randomized 1:1 to either the intervention or control group. The intervention group followed a pre‐post assessment approach, and the control group followed a test‐retest approach. The initial assessment showed that participants in both the intervention and control groups correctly performed less than half of the 14 skills considered necessary to obtain an accurate blood pressure measurement (mean scores 5.5 and 5.9, respectively). Following the e‐Learning module, the intervention group performed on average of 3.4 more skills correctly vs 1.4 in the control group (P < .01). Our findings reinforce existing evidence that errors in provider blood pressure measurements are highly prevalent and provide novel evidence that refresher training improves measurement accuracy.     

Health Technology Assessment Process for Oncology Drugs: Impact of CADTH Changes on Public Payer Reimbursement Recommendations

Public reimbursement systems face the challenge of balancing provision of needed treatments and the reality of limited resources. Canada has a complex system for drug approval and public reimbursement, with jurisdiction divided between the federal government and the provinces/territories. A pivotal role is that of health technology assessment (HTA), which relies primarily on health economic principles to analyze the value of drugs on a population health basis and make recommendations about public reimbursement. The Canadian Agency for Drugs and Technologies in Health (CADTH) provides recommendations to all provinces but Quebec. This article provides an overview of Canada’s approval and public reimbursement pathway, including the role of HTA and the economic principles on which it relies. Starting in late 2020, CADTH reduced the cost per quality-adjusted life year (QALY) threshold, the metric relied upon in making recommendations to public payers. An analysis of all 56 oncology drug final recommendations issued from January 2020 to January 2022 was conducted and confirms this reduction in the cost per QALY threshold. As a result of this threshold reduction, recommendations to the provinces include, in a number of cases, substantially greater price reductions. The potential implications for successful price negotiation with the pan-Canadian Pharmaceutical Alliance (pCPA), the public negotiating body for the provinces, are discussed.     

Systemic Therapy and Its Surgical Implications in Patients with Resectable Liver Colorectal Cancer Metastases. A Report from the Western Canadian Gastrointestinal Cancer Consensus Conference

The Western Canadian Gastrointestinal Cancer Consensus Conference (WCGCCC) convened virtually on 4 November 2021. The WCGCCC is an interactive multi-disciplinary conference attended by health care professionals, including surgical, medical, and radiation oncologists; pathologists; radiologists; and allied health care professionals from across four Western Canadian provinces, British Columbia, Alberta, Saskatchewan, and Manitoba, who are involved in the care of patients with gastrointestinal cancer. They participated in presentation and discussion sessions for the purpose of developing recommendations on the role of systemic therapy and its optimal sequence in patients with resectable metastatic colorectal cancer.     

Nutraceuticals for Androgenetic Alopecia

BackgroundSeveral oral nutraceuticals have recently emerged as products marketed to increase hair growth and thickness. However, these supplements typically lack the rigorous testing and statistically significant data that apply to pharmaceuticals. Therefore, the potential benefits of oral nutraceuticals for conditions of hair loss, such as androgenetic alopecia, have yet to be fully understood by dermatologists. ObjectiveThe purpose of this article is to evaluate current studies in the literature to assess the efficacy of popular oral nutraceuticals marketed for hair growth in subjects with androgenetic alopecia.MethodsThis article reviews the currently available literature on the nutraceuticals Nutrafol^® and Viviscal^® for hair growth and describes and evaluates the results observed.ResultsOral nutraceuticals are effective to a modest degree in promoting hair growth in men and women with androgenetic alopecia.ConclusionOral nutraceuticals have demonstrated efficacy in promoting modest hair growth in men and women with androgenetic alopecia and may serve as useful adjuncts to current treatments. As the popularity of nutraceuticals grows, it is important for dermatologists to be knowledgeable of the potential benefits and pitfalls of these supplements to appropriately counsel patients seeking treatment for hair loss.     

Testing two process models of religiosity and sexual behavior

Adolescents who are more religious are less likely to have sex, but the process by which religiosity impacts sexual behavior is not well established. We tested two potential processes, involving: (1) whether religiosity suppressed individuals' motivations to have sex for physical pleasure, and (2) whether individuals internalized their religions' teachings about sex for pleasure. College students (N = 610, 53.8% female, M age = 18.5, 26.1% Hispanic Latino [HL], 14.9% non-HL African American, 23.8% non-HL Asian American/Pacific Islander, 26.3% non-HL European American and 8.9% non-HL multiracial) completed web surveys during their first three semesters. Religiosity did not moderate the association between students' motivations for sex for pleasure and sexual behavior. Motivations mediated the association between religiosity and sexual behavior, suggesting that religion does not override adolescents' existing motivations, but instead, religious adolescents internalize norms about sexual behavior.

Stay True to Your Workout: Does Repeated Physical Testing Boost Exercise Attendance? A One-Year Follow-Up Study

No prospective studies have investigated if repeated testing of physical performance and body composition are associated with exercise attendance or patterns in fitness club members. This study aimed to investigate if repeated physical testing was associated with exercise attendance and patterns in gym members and to report prospective data on use of the fitness club`s facilities and products. Untrained new members were recruited and divided into a test group (n = 125) and as controls (n = 125). All participants answered a survey including exercise involvement, at onset, and after 3, 6, and 12 months follow-up. The test group also measured body composition, maximal oxygen uptake, and maximal muscle strength (onset, and after 3 and 12 months). In total 73.6% answered all surveys, and in the test group, 44.8% completed all physical tests. Regular exercise attendance was defined as ≥2 sessions/week. Repeated testing showed no association with long-term regular exercise attendance (test group: 19.6%, controls: 19.8%; p = 0.638). At 3 months, a lower proportion in the test group reported engagement in resistance exercise (35.3% and 60.2%; p = 0.003) and had lower exercise frequency (2.0 and 2.6 days/week; p = 0.008) than controls. The test group had higher participation in group exercise classes (28.0% and 13.6%; p = 0.040). Exercise frequency decreased from onset to 12 months (from 2.6 to 2.2 days/week; p = 0.025) At 3, 6, and 12 months, 51.8%, 37.6%, and 37.4% reported regular exercise attendance, and 16.9% at all follow-ups. At all time-points, most common workout mode was individual resistance exercise (43.8% to 46.3%). Few attended group exercise classes (7.5% to 13.8%) or used a personal trainer (22.5% to 27.5%). Repeated physical testing did not improve exercise attendance, and we found no changes in members` use of the fitness club`s facilities and products. Only 16.9% reported regular exercise attendance throughout the first year of membership.Key points

• To the authors knowledge this is the first study investigating if repeated physical testing was associated with exercise attendance and patterns in fitness club members.
• The results showed that repeated testing of physical performance and body composition was not associated with exercise attendance.
• With only 17% exercising two days or more per week during the first year of membership, our results indicate that there is a need to develop strategies to improve exercise attendance among new recreational exercisers.
