J Nutr Health Aging

January 2025

Faculty of Medicine and Health, School of Health Sciences and Sydney Medical School, University of Sydney, New South Wales, Australia, and Hinda and Arthur Marcus Institute for Aging Research, Hebrew SeniorLife, Roslindale, MA, United States.

Article Synopsis
  • Aging leads to physiological changes and increased disease vulnerability, culminating in higher mortality rates as individuals get older.
  • Regular physical activity (PA) and exercise can counteract aging effects, improve health span, and reduce the risk of chronic diseases such as heart disease and cancer.
  • Personalized exercise plans, including various forms of training like aerobic and resistance exercises, are essential for maintaining health and functionality in older adults, particularly those with age-related issues.

Translational Neuroimaging Laboratory, The McGill University Research Centre for Studies in Aging, McConnell Brain Imaging Centre, Montreal Neurological Institute, McGill University, Montreal, Quebec, Canada.

Background And Objectives: To compare the diagnostic performance of an immunoassay for plasma concentrations of phosphorylated tau (p-tau) 217 with visual assessments of fluorine-18 fluorodeoxyglucose [F]FDG-PET in individuals who meet appropriate use criteria for Alzheimer dementia (AD) biomarker assessments.

Methods: We performed a retrospective analysis of individuals with early-onset (age <65 years at onset) and/or atypical dementia (features other than memory at onset), who were evaluated at a tertiary care memory clinic. All participants underwent measurements of CSF biomarkers (Aβ42, p-tau181, and total tau levels), as well as [F]FDG-PET scans, amyloid-PET scans, and plasma p-tau217 quantifications.

Postgraduate Program in Genetics and Molecular Biology, Universidade Federal do Rio Grande do Sul (UFRGS), Porto Alegre, RS, Brazil.

Article Synopsis
  • - GLUT1 deficiency syndrome is a genetic disorder that leads to low glucose levels in the brain, causing symptoms like seizures, developmental delays, and movement disorders, which can vary in severity.
  • - Treatment typically involves a ketogenic diet that provides an alternative energy source for the brain.
  • - The study identifies a new genetic mutation in a preschool child with atypical symptoms and highlights the need for genetic testing in patients with developmental delays.

Article Synopsis
  • The study evaluated the effectiveness of telemedicine, specifically nurse phone calls, in managing type 2 diabetes for patients transitioning to primary care after discharge from a tertiary clinic.
  • In a randomized clinical trial with 147 patients, there was no significant difference in HbA1c levels (a marker of blood sugar control) after 12 months between those who received telemedicine support and those who underwent standard care.
  • Overall, both groups maintained reasonable glycemic control, indicating that transitioning to primary care, with or without additional telemedicine support, was effective and safe for managing type 2 diabetes.

Dietary Intake of Micronutrients and Use of Vitamin and/or Mineral Supplements: Brazilian National Food Survey.

Nutrients

November 2024

Postgraduate Program in Epidemiology, School of Medicine, Universidade Federal do Rio Grande do Sul, Porto Alegre 90035-190, Rio Grande do Sul, Brazil.

Background/objectives: Vitamin and/or mineral supplements are designed to correct micronutrient deficiencies or maintain adequate intake. However, evidence suggests the indiscriminate use of these products, particularly among populations that already meet their micronutrient requirements through diet. This study aims to estimate the prevalence of vitamin and/or mineral supplement use and assess the dietary intake of micronutrients among users and non-users in the Brazilian adult and elderly populations.

Background: Detraining refers to the decline in physical fitness that occurs after the cessation of exercise, compromising the adaptations resulting from regular exercise training. To understand how long the benefits acquired from an exercise program can be maintained, the present study evaluated the detraining effects of a 4-week exercise cessation period in older adults who performed combined training at various weekly frequencies for 12 weeks.

Methods: This randomized controlled trial assigned participants to one of two training programs: a combined training program twice a week (CT2) or four times a week (CT4) over a period of 12 weeks, followed by a four-week detraining period.

Gut microbiota and gut-derived metabolites are altered and associated with dietary intake in women with polycystic ovary syndrome.

J Ovarian Res

November 2024

Postgraduate Program in Endocrinology and Metabolism, School of Medicine, Universidade Federal do Rio Grande do Sul (UFRGS), Porto Alegre, 90035-003, Brazil.

Background: Disturbances in the gut microbiota may act as mechanisms influencing the interplay between dietary factors and metabolic disorders. Studies have demonstrated that these alterations are associated with the diagnosis of polycystic ovary syndrome (PCOS). Within this context, we aimed to investigate associations between gut microbiota, gut-derived metabolites (short-chain fatty acids [SCFAs] and indole-3-propionic acid [IPA]), and dietary intake in women with PCOS.

Background: Transcranial direct current stimulation (tDCS) might modulate neural activity and promote neural plasticity in patients with fibromyalgia (FM). This multi-group randomized clinical trial compared home-based active tDCS (HB-a-tDCS) on the left dorsolateral prefrontal cortex (l-DLPFC) or home-based sham tDCS (HB-s-tDCS), and HB-a-tDCS or HB-s-tDCS on the primary motor cortex (M1) in the connectivity analyses in eight regions of interest (ROIs) across eight resting-state electroencephalography (EEG) frequencies.

Methods: We included 48 women with FM, aged 30 to 65, randomly assigned to 2:1:2:1 to receive 20 sessions during 20 minutes of HB-a-tDCS 2mA or HB-s-tDCS, over l-DLPFC or M1, respectively.
