Effects of different warm-up methods on 50-meter breaststroke swimming performance.

Purpose: To examine the effects of different warm-up methods on 50 m breaststroke performance in both breaststroke specialists and individual medley swimmers.

Methods: 18 swimmers (breaststroke group: 9, individual medley group: 9) who met the qualification standards for the National Intercollegiate Athletic Games participated in this study. Each participant completed four different warm-up protocols (a conventional 1,400 m warm-up and a 700 m conventional warm-up that integrated tubing-assisted (TA), paddle (PD), or squat (SQ) warm-ups) over four separate days.

Sialidase fusion protein protects against influenza infection in a cigarette smoke-induced model of COPD.

First- and secondhand smokers are at an increased risk for influenza virus (IFV)-related respiratory failure and death. Despite approved influenza antiviral treatments, there is an unmet need for treatments that can improve outcomes in populations at risk for respiratory failure, including tobacco users with Chronic Obstructive Pulmonary Disease (COPD). Here we show that the sialidase fusion protein, DAS181, reduced viral burden, mitigated inflammation, and attenuated lung function loss, consistent with broad-spectrum anti-influenza responses in a mouse model of COPD and IFV-A infection.

Association between non-alcoholic fatty liver disease and progression of abdominal aortic aneurysm: a multicenter study.

Background: The purpose of our study was to investigate the association between non-alcoholic fatty liver disease (NAFLD) and abdominal aortic aneurysms (AAA) progression using non-enhanced computed tomography (CT) and CT angiography (CTA).

Methods: Patients with AAA and age- and sex-matched healthy subjects who underwent abdominal CTA and non-enhanced CT examination between January 2015 and January 2023 from four hospitals were retrospectively analyzed. Patients with AAA were divided into progression (growth rate > 10 mL/year) and non-progression groups, as well as those with NAFLD and without NAFLD, based on abdominal CT results.

Acute zonal occult outer retinopathy (AZOOR) complex associated with torpedo retinopathy following COVID-19 recombinant mRNA vaccination: a case report of a rare clinical presentation.

Background: While vaccination remains crucial in mitigating the impact of the COVID-19 pandemic, several ocular adverse events has been reported, including Acute Zonal Occult Outer Retinopathy (AZOOR) complex.

Case Presentation: A 31-year-old female presented declined best corrected visual acuity (BCVA) and flashes in both eyes three days following second recombinant mRNA COVID-19 vaccine (Moderna). Fundus autofluorescence (FAF) illustrated speckled hyper-AF lesions surrounding right eye torpedo maculopathy site and hyper-AF lesions in the left macula.

Risk of hemorrhagic fever with renal syndrome associated with meteorological factors in diverse epidemic regions: a nationwide longitudinal study in China.

Background: Hemorrhagic fever with renal syndrome (HFRS) is a climate-sensitive zoonotic disease that poses a significant public health burden worldwide. While previous studies have established associations between meteorological factors and HFRS incidence, there remains a critical knowledge gap regarding the heterogeneity of these effects across diverse epidemic regions. Addressing this gap is essential for developing region-specific prevention and control strategies.
