Caloric restriction (CR) slows biological aging and prolongs healthy lifespan in model organisms. Findings from CALERIE-2 - the first ever randomized, controlled trial of long-term CR in healthy, non-obese humans - broadly supports a similar pattern of effects in humans. To expand our understanding of the molecular pathways and biological processes underpinning CR effects in humans, we generated a series of genomic datasets from stored biospecimens collected from n=218 participants during the trial. These data constitute the first publicly-accessible genomic data resource for a randomized controlled trial of an intervention targeting the biology of aging. Datasets include whole-genome SNP genotypes, and three-timepoint-longitudinal DNA methylation, mRNA, and small RNA datasets generated from blood, skeletal muscle, and adipose tissue samples (total sample n=2327). The CALERIE Genomic Data Resource described in this article is available from the Aging Research Biobank. This mult-itissue, multi-omic, longitudinal data resource has great potential to advance translational geroscience.

Survey of psychological resilience among university students majoring in long-term-care-related disciplines in Taiwan.
BMC Psychol
December 2024
Fire Department, New Taipei City Government, New Taipei City, Taiwan.
Background: The psychological resilience of university students majoring in long-term-care (LTC)-related disciplines is crucial for workforce retention and effective care provision in this field. This study aims to investigate the differences in levels of psychological resilience among these students in Taiwan.
Methods: This cross-sectional study involved 258 participants selected via stratified random sampling from 23 universities across Taiwan from November 2021 to November 2022, representing a diverse educational context.
Barriers to PrEP use and adherence among adolescent girls and young women in Eastern, Southern, and Western Africa: a scoping review.
BMC Womens Health
December 2024
Department of Public Health Institute of Tropical Medicine, Antwerp, Belgium.
Background: Adolescent girls and young women (AGYW) are disproportionately affected by HIV. Globally, in 2022, an estimated 4000 AGYW 15-24 were newly infected with HIV weekly, and nearly 78% of these infections occurred in sub-Saharan Africa. Oral Pre-Exposure Prophylaxis (PrEP) is a key HIV prevention option within an overall HIV combination prevention approach with an efficacy of over 90% when taken correctly.

BMC Palliat Care
December 2024
Faculty of Medicine and Health Technology, Tampere University, Arvo Ylpön katu 34, Tampere, 33520, Finland.
Background: Patients with chronic nonmalignant pulmonary disease and lung cancer both need palliative care, but palliative care services may be better adjusted to serve cancer patients. We compared the timing and clinical practice of palliative care and acute hospital usage during the last year of life in patients with nonmalignant pulmonary disease or lung cancer.
Methods: This was a retrospective study of all patients in a palliative care phase (palliative goal of care) with nonmalignant pulmonary disease or lung cancer who were treated at Tampere University Hospital, Finland, during the years 2018-2020.
Access to specialist plastic surgery in rural vs. Urban areas of Africa.
BMC Surg
December 2024
Department of Research and Education, Oli Health Magazine Organization, Research and Education, Kigali, Rwanda.
Introduction: Plastic surgery is an essential yet underdeveloped field in many African nations, especially in rural areas. The demand for plastic surgery is increasing, but differences in access to respective services between rural and urban domiciles remain ever existent, despite the exponentiation of trauma, burns, and congenital disorders. According to this review, urban areas have access to better facilities and specialized surgeons, while rural areas frequently lack infrastructure, educated healthcare personnel, and medical resources.
