Low handgrip strength is associated with falls after the age of 50: findings from the Brazilian longitudinal study of aging (ELSI-Brazil).
Arch Public Health
October 2024
Article Synopsis
- The study aimed to explore how low handgrip strength (HGS) relates to the risk of falls in middle-aged and older adults, analyzing data from the Brazilian Longitudinal Study of Aging.
- It involved 8,112 participants aged 50 to 105, revealing that 21.5% experienced at least one fall and that HGS declines steadily with age.
- The findings indicate that low HGS significantly contributes to fall risk in individuals through their 50s and continues to be an important factor until the 80s, even when accounting for other health variables.
Distinct Responses of Cystic Fibrosis Epithelial Cells to SARS-CoV-2 and Influenza A Virus.
Am J Respir Cell Mol Biol
September 2024
The COVID-19 pandemic has underscored the impact of viral infections on individuals with cystic fibrosis (CF). Initial observations suggested lower COVID-19 rates among CF populations; however, subsequent clinical data have presented a more complex scenario. This study aimed to investigate how bronchial epithelial cells from CF and non-CF individuals, including various CF transmembrane conductance regulator (CFTR) mutations, respond to infection with SARS-CoV-2 variants and SARS-CoV.

- Soil microbes are crucial for plant growth, but understanding their complex interactions in natural environments is still lacking, particularly when multiple microbial species are involved.* -
- A meta-analysis was conducted to explore how bacteria and mycorrhizal fungi interact and affect various plant growth traits, revealing mostly positive additive effects, except for some unique responses in ectomycorrhizal plants.* -
- These results indicate that findings from controlled studies can apply to real-world settings, supporting the idea of using diverse beneficial microbes to enhance plant growth.*
Enigmatic sarcopenic obesity is still a challenge for science and adds to the global public health burden. The progressive accumulation of body fat combined with a dysfunctional skeletal muscle structure and composition, oxidative stress, mitochondrial dysfunction, and anabolic resistance, among other aggravating factors, together represent the seriousness and complexity of treating the metabolic disorder of sarcobesity in aging. For this reason, further studies are needed that encourage the support of therapeutic management.

Climate change effects, including shifts in rainfall patterns and rising temperatures, may alter the functionality of soil microbial communities, leading to uncertain changes in CH cycling dynamics. To investigate the microbial feedback under climate change scenarios, we performed a microcosm experiment using soils from two floodplains (i.
