Background: Although Seasonal Influenza Vaccination (SIV) is a crucial preventive measure, achieving sufficient coverage to completely control influenza epidemics poses a significant challenge. This study aims to evaluate optimal strategies for SIV to prevent high-intensity level of influenza epidemics in Zhejiang Province, China. High-intensity outbreaks were defined as weekly incidence rates above 72.

Infertility presents a substantial challenge for women of reproductive age, exerting profound effects on both individual well-being and healthcare systems. Despite its critical role in folate and homocysteine pathways, the influence of methylenetetrahydrofolate reductase (MTHFR) on the success of assisted reproductive techniques (ART) remains insufficiently understood. This knowledge gap impedes the development of personalized therapeutic strategies.

This study examined global trends in influenza-associated lower respiratory infections (LRIs) deaths from 1990 to 2019 using data from the GBD 2019. The annual percentage change (APC) and average annual percentage change (AAPC) were used to analyze age-standardized death rates (ASDR). Globally, the ASDR of influenza-associated LRIs was 3.

Immune memory is crucial for preventing hepatitis E virus (HEV) infection. Our study aims to investigate immunological memory characteristics and differences between vaccination and natural HEV infection, taking into account that both can induce immune memory. We recruited 60 HEV-infected patients, 58 contingency HEV-vaccinated individuals and 4 controls from an outbreak of hepatitis E in a nursing home between June and August 2023.

Objectives: During the COVID-19 pandemic, global health systems faced unprecedented challenges, as well as in maternal and neonatal health, thus this study aims to clarify the impacts of COVID-19 on maternal and neonatal disorders (MNDs), regional variations, and the role of economic support.

Methods: We have developed a counterfactual model integrating Autoregressive Integrated Moving Average and Long Short-Term Memory models to forecast the burden of MNDs from 2020 To et al., 2021, which was compared with the actual burden to quantify the specific impact of the COVID-19 pandemic on MNDs.

Background & Aims: Given the impact of nonalcoholic fatty liver disease (NAFLD) on T cell activation and proliferation functions, we aim to explore the heterogeneity of follicular cytotoxic T (Tfc) cells in chronic hepatitis B (CHB) patients with NAFLD.

Methods: 32 healthy controls (HCs), 36 treatment-naïve CHB patients, and 19 treatment-naïve CHB + NAFLD patients were recruited. We employed multicolor flow cytometry to assess the exhausted phenotype and functionality of Tfc cells.

Background: This study aimed to investigate epidemiologic characteristics of major human infection with avian influenza and explore the factors underlying the spatial distributions, particularly H5N6 and H9N2, as H9N2 could directly infect mankind and contribute partial or even whole internal genes to generate novel human-lethal reassortants such as H5N6. They pose potential threats to public health and agriculture.

Methods: This study collected cases of H5N1, H5N6, H9N2, and H7N9 in China, along with data on ecoclimatic, environmental, social and demographic factors at the provincial level.

The optoelectronic, electrocatalytic, and photocatalytic properties of new tin selenides are of great significance for various energy applications. Herein, a facile solvothermal reaction of Sn, Se, and MnCl in 1,3-propodiamine (1,3-dap) solution at 150 °C for 7 days was used to achieve a new type of one-dimensional (1D) organic hybrid manganese-tin selenide [Mn(1,3-dap)(μ-1,3-dap)SnSe] (), whose 1D framework is built up from the linkage of rare unsaturated binuclear [Mn(1,3-dap)(μ-1,3-dap)] cations and dimeric [SnSe] anions. The combination of and Ni nanoparticle is first applied for the preparation of a Ni//NF electrode (NF = porous Ni foam) as the efficient electrocatalyst for the hydrogen evolution reaction (HER), indicating excellent HER electrocatalytic property with an overpotential of 117 mV at 10 mA·cm in a neutral medium.

Article Synopsis
  • The study analyzed global trends in acute respiratory infections (ARIs) from 1990 to 2021, focusing on upper respiratory infections (URIs) and lower respiratory infections (LRIs) using data from the Global Burden of Disease 2021.
  • In 2021, the incidence rate of URIs was highest in high-sociodemographic index (SDI) regions, while LRIs had the highest rates in low-SDI regions, highlighting geographic disparities in infection rates.
  • Although both incidence and death rates from ARIs decreased overall between 1990 and 2021, the COVID-19 pandemic caused a temporary spike in URI incidence, especially in higher SDI regions, indicating ongoing public health challenges.

The correlation between diabetes and coronary artery disease (CAD) is well established. Insulin resistance (IR) is considered a primary contributor to elevated CAD risk in diabetic individuals. The triglyceride-glucose (TyG) index serves as a straightforward surrogate marker for insulin resistance.

Objective: Accidental ingestion of button batteries (BB), usually occurred in children and infants, will rapidly erode the esophagus and result in severe complications, even death. It has been recommended that treatment of this emergent accident as soon as possible with drinking of pH-neutralizing viscous solutions such as honey and sucralfate before surgical removal can mitigate the esophageal injury. Recently, we reported that the electric insulating solutions such as edible oils could mitigate tissue damage in BB-exposed esophageal segments.

Long noncoding RNAs (lncRNAs) have been discovered to play a regulatory role in genomic instability (GI), which participates in the carcinogenesis of various cancers, including hepatocellular carcinoma (HCC). We endeavored to establish a GI-derived lncRNA signature (GILncSig) as a potential biomarker and explore its impact on immune infiltration and prognostic significance. Combining expression and somatic mutation profiles from The Cancer Genome Atlas database, we identified GI-related lncRNAs and conducted functional analyses on co-expressed genes.
