Moderate-Intensity Aerobic Exercise Restores Appetite and Prefrontal Brain Activity to Images of Food Among Persons Dependent on Methamphetamine: A Functional Near-Infrared Spectroscopy Study

This study used functional near-infrared spectroscopy (fNIRS) to measure the effects of moderate- and high-intensity short-term aerobic exercise on prefrontal activity related to food images and recorded the subjective feelings of appetite in methamphetamine-dependent users. In total, 56 men who met the Diagnostic and Statistical Manual of Mental Disorders (Fifth Edition) criteria for methamphetamine dependence, with a mean (SD) body mass index of 24.7 (3.5) kg/m2 and age of 30.2 (5.1) years, were randomly assigned to one of two exercise groups: moderate intensity (n = 28; 65%–75% of maximum heart rate) and high intensity (n = 28; 76%–85% of heart rate maximum). Each group also performed a resting control session for 35 min 1 week before or after the exercise, in a counterbalanced order. Mean oxygenated hemoglobin concentration changes in the PFC when viewing visual food cues were assessed by fNIRS, and subjective feelings of appetite were self-rated using visual analog scales after moderate- or high-intensity aerobic exercise and after the resting control session. A continuous-wave NIRS device was used to obtain functional data: eight sources and seven detectors were placed on the scalp covering the PFC, resulting in 20 channels per participant. We found that moderate-intensity aerobic exercise significantly increased both, the activation of the left orbitofrontal cortex (OFC) to images of high-calorie food (P = 0.02) and subjective sensations of hunger (F(1,54) ...

Authors: Shabataev V, Saadat SH, Elterman DS Abstract The two major long-term concerns associated with different options for the management of prostate cancer, (including surgery, radiotherapy, brachytherapy, cryotherapy, HIFU, etc.) include difficulties with lower urinary tract symptoms (LUTS) and/or erectile dysfunction. LUTS can be in the form of stress urinary incontinence (SUI), urge urinary incontinence (UUI), frequency/urgency, and/or voiding difficulties. While surgery is mostly associated with SUI and radiation mostly results in UUI, there can be an overlap. Incontinence rates after cryotherapy and high in...

Authors: Magee DE, Singal RK Abstract Our objective is to provide an up-to-date summary of current literature on the indications for androgen deprivation therapy (ADT), ways in which ADT is used, and the main side effects associated with its use. MEDLINE (Pubmed) was searched for relevant papers published from database inception to May 1, 2019 for studies evaluating the use of ADT and its associated adverse events. ADT is a mainstay in the treatment of prostate cancer and is used throughout the disease course. While predominantly used in the metastatic setting, ADT has a role in the treatment of localized disease a...

Authors: Law KW, Nguyen DD, Barkin J, Zorn KC Abstract Prostate cancer screening remains highly controversial in medicine. The College of Family Physicians of Canada currently endorses positions that recommend against prostate-specific antigen (PSA) screening in men of all ages, while the Canadian Urological Association recommends shared and informed decision making for PSA screening in men 50-70 years old. Unfortunately, these opposing stances have left Family Physicians responsible for interpreting the appropriate course of action for their patients. Recent studies demonstrating an increase in incidence of metast...

Conclusion: Feeling healthy may exacerbate barriers to ART initiation. Strategies to reach healthy clients are needed, such as chronic care models, differentiated models of care that minimize disruptions to daily activities, and community sensitization on the benefits of early initiation.

Authors: Famakinde DO Abstract With the advent of CRISPR (clustered regularly interspaced short palindromic repeat)-based gene drive, present genetic research in schistosomiasis vector control envisages the breeding and release of transgenic schistosome-resistant (TSR) snail vectors to curb the spread of the disease. Although this approach is still in its infancy, studies focussing on production of genetically modified (GM) mosquitoes (including gene-drive mosquitoes) are well advanced and set the pace for other transgenic vector research. Unfortunately, as with other GM mosquitoes, open field release of gene-drive...
