Objectives: Although telomere length is an established marker of biological aging, the impact of religious beliefs on telomere length remains uncertain.
Methods: This cross-sectional study investigated the relationship between religiosity and telomere length among senior Brazilians, aged 60 and older. The study examined the association between organizational, non-organizational, and intrinsic religiosity with telomere length, adjusting for sociodemographic, mental, physical health, and medication. Hierarchical linear regression models were used.
Results: 821 participants (62.2 % female, mean age 68.9 years, SD = 6.48) were studied. Female gender and younger age were linked to longer telomeres, but no significant associations were found between religious beliefs and telomere length in adjusted or unadjusted models.
Conclusions: This study found no evidence of an association between religiosity and telomere length among older Brazilian adults. While prior research highlights religiosity's positive health effects, its direct influence on telomere length remains unclear, warranting further exploration.

Horticultural Sciences Department, University of Florida, IFAS Gulf Coast Research and Education Center, Wimauma, FL, 33598, USA.
Background: Cultivated strawberry (Fragaria xananassa Duch.), an allo-octoploid species arising from at least 3 diploid progenitors, poses a challenge for genomic analysis due to its high levels of heterozygosity and the complex nature of its polyploid genome.
Results: This study developed the complete haplotype-phased genome sequence from a short-day strawberry, 'Florida Brilliance' without parental data, assembling 56 chromosomes from telomere to telomere.
Associations of essential trace metals with telomere length in general population: a cross-sectional study.
Sci Rep

Department of Environmental and Occupational Health, School of Public Health, Guangxi Medical University, Shuangyong Road No. 22, Nanning, 530021, Guangxi, PR China.
This study investigated the relationship between essential plasma metals (Co, Cr, Cu, Mn, Mo, Se, Zn) and telomere length in 2,194 Chinese adults aged ≥ 30 years. Metal concentrations were measured using ICP-MS, and leukocyte relative telomere length (rTL) was assessed by qPCR. In the elderly, Cr and Mn were significantly positively correlated with rTL, while Mo, Zn, and Cu showed negative correlations.

Lung Transplant and ECMO Program, Department of Pulmonary, Critical Care and Sleep Medicine, University of Florida, Gainesville, Florida, USA. Electronic address:
Interstitial lung disease (ILD) is a known complication of Primary Sjögren's syndrome (SS). We report the case of a 56-year-old man with a history of SS (SS-A positive) who was admitted with ILD exacerbation, causing respiratory failure requiring extracorporeal life support. Given the family history of rapidly progressive ILD and mixed connective tissue disease in his brother, the patient was tested for short telomere syndrome (STS) during hospitalization and found to have leukocyte telomere length (LTL) around the first percentile, suggesting the diagnosis of STS.

Objective: Telomere plays a critical role in maintaining genomic stability, and its length serves as a marker of cellular aging. Emerging evidence projects telomere length as a clinical risk factor for metabolic diseases. Our current study examines the associations between telomere length and demographic factors including metabolic health in a multi-ethnic cohort to provide insight into the impact of ethnicity on the potential use of telomere length as a biomarker for assessing diabetes risk.

Background: Immigrant status and citizenship influence health and well-being, yet their associations with DNA methylation (DNAm)-based biomarkers of aging - key predictors of healthspan and lifespan, also known as epigenetic aging - remain underexplored.
Methods: Using a representative sample of 2,336 United States (U.S.
