Dietary N-6 Polyunsaturated Fatty Acid Intake and Brain Health in Middle-Aged and Elderly Adults.

Background: Dietary intake of polyunsaturated fatty acids (PUFA) plays a significant role in the onset and progression of neurodegenerative diseases. Since the neuroprotective effects of n-3 PUFA have been widely validated, the role of n-6 PUFA remains debated, with their underlying mechanisms still not fully understood.

Methods: In this study, 169,295 participants from the UK Biobank were included to analyze the associations between dietary n-6 PUFA intake and neurodegenerative diseases using Cox regression models with full adjustments for potential confounders.

Water quality and neurodegenerative disease risk in the middle-aged and elderly population.

Ensuring sustainable management of water is an indispensable part of sustainable development, however, the limelight on long-term health risk of water hardness is essential but remains inadequate. This study estimated effects of water hardness on the brain system to refine its systemic risk assessment. We assembled a cohort of 397,265 participants from the UK Biobank to investigate the associations of water hardness with neurodegenerative diseases and brain imaging phenotypes through modeling.

From tumor microenvironment to emerging biomarkers: the reshaping of the esophageal squamous cell carcinoma tumor microenvironment by neoadjuvant chemotherapy combined with immunotherapy.

Esophageal squamous cell carcinoma is a cancer with high morbidity and mortality. The advent of immune checkpoint inhibitors has significantly increased complete response rates and postoperative R0 resection rates after neoadjuvant therapy. These drugs can largely reverse the suppression of the immune system caused by the tumor microenvironment, allowing the reactivation of anti-tumor immune infiltrating cells, significantly improving the patient's tumor microenvironment, and thus preventing tumor development.

Plasma Polyunsaturated Fatty Acid Levels and Mental Health in Middle-Aged and Elderly Adults.

Polyunsaturated fatty acids (PUFAs) are promising nutrients for the prevention and management of psychiatric disorders. Both animal experiments and cohort studies have demonstrated the antidepressant effects of PUFAs, especially omega-3 PUFAs. However, inconsistent reports about specific types of PUFAs, such as the omega-3 and omega-6 PUFAs, still exist.

Long-term exposure to low-concentration sulfur dioxide and mental disorders in middle-aged and older urban adults.

The World Health Organization loosened the air quality guideline for daily sulfur dioxide (SO) concentrations from 20 μg/m to 40 μg/m. However, the guideline for SO concentrations in 2021 raised public concerns since there was no sufficient evidence that low-concentration SO exposure is harmless to the population's health, including mental health. We analyzed the associations between low-concentration SO exposure and incidence risks of total and cause-specific mental disorders, including depressive disorder, anxiety disorder, bipolar disorder, and schizophrenia spectrum disorder.

Global burden associated with rare infectious diseases of poverty in 2021: findings from the Global Burden of Disease Study 2021.

Background: Rare infectious diseases of poverty (rIDPs) involve more than hundreds of tropical diseases, which dominantly affect people living in impoverished and marginalized regions and fail to be prioritized in the global health agenda. The neglect of rIDPs could impede the progress toward sustainable development. This study aimed to estimate the disease burden of rIDPs in 2021, which would be pivotal for setting intervention priorities and mobilizing resources globally.

Global burden of enteric infections related foodborne diseases, 1990-2021: findings from the Global Burden of Disease Study 2021.

Background: Understanding the global burden of enteric infections is crucial for prioritizing control strategies for foodborne and waterborne diseases. This study aimed to assess the global burden of enteric infections in 2021 and identify risk factors from One Health aspects.

Methods: Leveraging the Global Burden of Disease (GBD) 2021 database, the incidence, disability-adjusted life years (DALYs), and deaths of enteric infections and the subtypes were estimated, including diarrheal diseases, typhoid and paratyphoid fever, invasive non-typhoidal (iNTS) infections, and other intestinal infectious diseases.

Chronic Low-Grade Inflammation and Brain Structure in the Middle-Aged and Elderly Adults.

Low-grade inflammation (LGI) mainly acted as the mediator of the association of obesity and inflammatory diet with numerous chronic diseases, including neuropsychiatric diseases. However, the evidence about the effect of LGI on brain structure is limited but important, especially in the context of accelerating aging. This study was then designed to close the gap, and we leveraged a total of 37,699 participants from the UK Biobank and utilized inflammation score (INFLA-score) to measure LGI.

Associations of long-term exposure to low-level PM and brain disorders in 260,922 middle-aged and older adults.

Long-term exposure to high-level ambient PM was associated with increased risks of brain disorders, while the associations remain uncertain when the exposure is lower than current air quality standards in numerous countries. This study aimed to assess the effects of PM exposure on the brain system in the population with annual mean concentrations ≤15 μg/m. We analyzed data from 260,922 participants without preexisting brain diseases at baseline in the UK Biobank.

Protein Restriction Effects on Healthspan and Lifespan in Drosophila melanogaster Are Additive With a Longevity-Promoting Diet.

Aging of the organism is associated diminished response to external stimuli including weakened immune function, resulting in diseases that impair health and lifespan. Several dietary restriction modalities have been reported to improve health and lifespan in different animal models, but it is unknown whether any of the lifespan-extending dietary treatments could be combined to achieve an additive effect. Here, we investigated the effects of halving amino acids components in the HUNTaa diet, a synthetic medium known to extend lifespan in Drosophila.

Excess Deaths of Gastrointestinal, Liver, and Pancreatic Diseases During the COVID-19 Pandemic in the United States.

To evaluate excess deaths of gastrointestinal, liver, and pancreatic diseases in the United States during the COVID-19 pandemic. We retrieved weekly death counts from National Vital Statistics System and fitted them with a quasi-Poisson regression model. Cause-specific excess deaths were calculated by the difference between observed and expected deaths with adjustment for temporal trend and seasonality.

Overexpression Extends Lifespan and Healthspan in .

Autophagy plays important but complex roles in aging, affecting health and longevity. We found that, in the general population, the levels of and decreased during aging, yet they are upregulated in centenarians, suggesting that overexpression of ATG4 members could be positive for healthspan and lifespan. We therefore analyzed the effect of overexpressing (a homolog of human ) in , and found that, indeed, overexpression increased resistance to oxidative stress, desiccation stress and fitness as measured by climbing ability.
