Background: Sarcopenia involves the loss of skeletal muscle mass and age-related functionality; it diminishes physical independence, health and quality of life. In 2016 it was added to the International Classification of Diseases (ICD-10). Information about the frequency of sarcopenia among Mexican older adults is scarce. The objective was to analyze associated factors with sarcopenia in Mexican older adults through the 2012 National Health and Nutrition Survey data.
Methods: Cross-sectional study which included subjects of 60 years of age or more with simultaneous information on health and anthropometry questionnaires from the 2012 National Health and Nutrition Survey. Sarcopenia was diagnosed through a gait speed test and calf circumference. It was assessed the prevalence of sarcopenia and its association with sociodemographic characteristics and variables related to health, tobacco use and alcohol consumption. The analysis was performed with SPSS v. 16.
Results: We analyzed a sample of 5046 older adults who represented 7 439 686 older adults nationwide. Among subjects 53.9% (n = 2718) were women (mean age 69.92 ± 7.56 years) and 46.1% (n = 2328), men (mean age 70.43 ± 7.73 years). Prevalence of presarcopenia was 8.70% and sarcopenia, 13.30%.
Conclusion: Sarcopenia was more prevalent in women and it increases with age. It has a significant relationship with falls, cognitive impairment, central obesity and high levels of marginalization.

: Major Depressive Disorder (MDD) is a prevalent and debilitating mental disorder that has been linked to hyperhomocysteinemia and folate deficiency. These conditions are influenced by the methylenetetrahydrofolate reductase () gene, which plays a crucial role in converting homocysteine to methionine and is essential for folate metabolism and neurotransmitter synthesis, including serotonin. : This study explored the association between and polymorphisms among Saudi MDD patients attending the Erada Complex for Mental Health and Erada Services outpatient clinic in Jeddah, Saudi Arabia.

This study aimed to determine the risk of emergency admission by ambulance in patients taking potentially inappropriate medications (PIMs). We included 273,932 patients aged over 75 years of age admitted between January 1, 2019, and December 31, 2019, using the Japan Medical Data Center medical insurance database containing anonymized patient data. We excluded patients without a history of admission.

Whilst efficient movement through space is thought to increase the fitness of long-distance migrants, evidence that selection acts upon such traits remains elusive. Here, using 228 migratory tracks collected from 102 adult breeding common terns (Sterna hirundo) aged 3-22 years, we find evidence that older terns navigate more efficiently than younger terns and that efficient navigation leads to a reduced migration duration and earlier arrival at the breeding and wintering grounds. We additionally find that the age-specificity of navigational efficiency in adult breeding birds cannot be explained by within-individual change with age (i.

Background: Superagers, older adults with exceptional cognitive abilities, show preserved brain structure compared to typical older adults. We investigated whether superagers have biologically younger brains based on their structural integrity.
Methods: A cohort of 153 older adults (aged 61-93) was recruited, with 63 classified as superagers based on superior episodic memory and 90 as typical older adults, of whom 64 were followed up after two years.
Age determination by measurement of pulp volume of canine teeth in patients with cleft lip and palate: a retrospective study.

Objectives: This study evaluates the potential of pulp volume/total tooth-volume measurements of canine teeth in relation to chronologic age in patients with cleft lip and palate (CLP). The significance of this study lies in its exploration of the usability of these measurements for age determination in CLP patients, providing a novel perspective to the existing literature.
Methods: Cone beam computed tomography images of 33 patients (16 females, 17 males) with unilateral CLP aged 14-45 years and 33 age- and sex-matched healthy individuals (16 females, 17 males) were retrospectively evaluated.
