The Uptake of the Influenza Vaccine in Patients With Cystic Fibrosis: A Retrospective Study.

Background: Children with cystic fibrosis are more likely to become severely unwell with influenza-associated illness compared to children without chronic lung disease. The provision of accessible influenza vaccinations is essential in the prevention of infection.

Objectives: To describe the prevalence of the influenza vaccine uptake in children with cystic fibrosis from 2016 to 2020 at a single tertiary paediatric hospital site and determine if the COVID pandemic of 2020 and the introduction of telehealth encounters affected the vaccine uptake.

Perception of Socioeconomic Status: A Meta-Analysis of Manipulations.

The causal effects of one's socioeconomic status (SES) on outcomes are typically examined by experimentally manipulating SES self-perceptions based on one of three SES dimensions-absolute resource, relative resource, and general social position. We investigated the efficacy of these manipulations by systematically meta-analyzing their effects on SES self-perceptions. Based on 107 eligible samples ( = 26,203), manipulations of SES self-perceptions across the three SES dimensions were effective overall ( = 0.

Dengue and Zika virus NS4B proteins differ in topology and in determinants of ER membrane protein complex dependency.

Flaviviruses utilize the cellular endoplasmic reticulum (ER) for all aspects of their lifecycle. Genome replication and other viral activities take place in structures called replication organelles (ROs), which are invaginations induced in the ER membrane. Among the required elements for RO formation is the biogenesis of viral nonstructural proteins NS4A and NS4B.

An osteopathic assessment of lower extremity somatic dysfunctions in runners.

Context: Runners often experience acute/chronic pain due to pre-existing structural somatic dysfunction and/or acquired various overuse injuries of the lower extremity, specifically affecting the ligaments, tendons, muscles, and bones. Common structural and function dysfunctions include but are not limited to patellofemoral pain syndrome (PFPS), Achilles tendonitis, iliotibial band syndrome (ITBS), ligamentous and muscle tears, muscle sprains/strains, stress fractures, pes planus, plantar fasciitis, and shin splints.

Objectives: The purpose of this study is to assess the correlation between acute and chronic pain, overuse injuries, and observational and palpatory findings upon evaluation to establish common trends of somatic dysfunctions and determine possible etiology of the pain/injury.

Insights from the international workshop on "Adapting agriculture to climate change and air pollution".

An international workshop on "Adapting Agriculture to Climate Change and Air Pollution" took place at Nanjing University of Information Science and Technology, Nanjing, China, during 23-27 October, 2023. Experts working in various multi-disciplinary areas of agroecosystem and environmental research gathered for academic communication and discussions. Two discussion groups focused on "agriculture under air pollution and climate change: current challenges and priorities for the future" and "adapting agriculture to air pollution and climate change: current status and next steps.

Effect of aspirin on biomarker profile in women at high risk for preeclampsia.

Background: There is limited evidence in the literature regarding the temporal changes of preeclampsia-related biomarkers during pregnancy in high-risk women who develop preeclampsia despite the administration of aspirin prophylaxis.

Objective: This study aimed to compare the temporal changes in mean arterial pressure, uterine artery pulsatility index, placental growth factor, and soluble fms-like tyrosine kinase-1 across gestation in women identified as having high risk for preterm preeclampsia receiving aspirin prophylaxis and low-risk women without aspirin treatment.

Study Design: This was a prospective longitudinal nested case-control study of 2007 women with singleton pregnancies who participated in the first-trimester screen-and-prevent program for preeclampsia at the Prince of Wales Hospital, Hong Kong Special Administrative Region, China, between January 2020 and May 2023.

Mechanisms underlying the roles of leukocytes in the progression of cystic fibrosis.

Recent advances in cystic fibrosis (CF) treatments have led to improved survival, with life expectancy for Australians living with CF at 57yo. As life expectancy improves, long-term cardiovascular disease risk factors (as for the general population) will become an issue in these patients. We hypothesized that increased leukocyte expression of vasoconstriction and pro-fibrotic mediators may contribute to CF severity in adults with CF.

Sensitivity Analysis for Attributable Fraction in the Presence of Unmeasured Confounding.

A main goal of epidemiology is to provide an impact of an exposure on health outcomes. The attributable fraction (AF) is a widely used measure for quantifying its contribution. Various methods have been developed to estimate AF, including standardization, inverse probability of treatment weighting, and doubly robust methods.

Betamethasone improved near-term neonatal lamb lung maturation in experimental maternal asthma.

Maternal asthma is associated with increased rates of neonatal lung disease, and fetuses from asthmatic ewes have fewer surfactant-producing cells and lower surfactant-protein B gene (SFTPB) expression than controls. Antenatal betamethasone increases lung surfactant production in preterm babies, and we therefore tested this therapy in experimental maternal asthma. Ewes were sensitised to house dust mite allergen, and an asthmatic phenotype induced by fortnightly allergen lung challenges; controls received saline.

Examining the causal association between moderate alcohol consumption and cardiovascular risk factors in the Taiwan Biobank: a Mendelian randomization analysis.

Background: The Mendelian randomization approach uses genetic variants as instrumental variables to study the causal association between the risk factors and health outcomes of interest. We aimed to examine the relation between alcohol consumption and cardiovascular risk factors using two genetic variants as instrumental variables: alcohol dehydrogenase 1B () rs1229984 and aldehyde dehydrogenase 2 () rs671.

Methods: Using data collected in the Taiwan Biobank-an ongoing, prospective, population-based cohort study-our analysis included 129,032 individuals (46,547 men and 82,485 women) with complete data on rs1229984 and rs671 genotypes and alcohol drinking status.

TongGuanWan Alleviates Doxorubicin- and Isoproterenol-Induced Cardiac Hypertrophy and Fibrosis by Modulating Apoptotic and Fibrotic Pathways.

Heart failure, a major public health issue, often stems from prolonged stress or damage to the heart muscle, leading to cardiac hypertrophy. This can progress to heart failure and other cardiovascular problems. Doxorubicin (DOX), a common chemotherapy drug, and isoproterenol (ISO), a β-adrenergic agonist, both induce cardiac hypertrophy through different mechanisms.

SLC4A11 mediates ammonia import and promotes cancer stemness in hepatocellular carcinoma.

End-stage liver disease is marked by portal hypertension, systemic elevations in ammonia, and development of hepatocellular carcinoma (HCC). While these clinical consequences of cirrhosis are well described, it remains poorly understood whether hepatic insufficiency and the accompanying elevations in ammonia contribute to HCC carcinogenesis. Using preclinical models, we discovered that ammonia entered the cell through the transporter SLC4A11 and served as a nitrogen source for amino acid and nucleotide biosynthesis.

Estimating future climate change impacts on human mortality and crop yields via air pollution.

Future climate change may bring local benefits or penalties to surface air pollution, resulting from changing temperature, precipitation, and transport patterns, as well as changes in climate-sensitive natural precursor emissions. Here, we estimate the climate penalties and benefits at the end of this century with regard to surface ozone and fine particulate matter (PM[Formula: see text]; excluding dust and smoke) using a one-way offline coupling between a general circulation model and a global 3-D chemical-transport model. We archive meteorology for the present day (2005 to 2014) and end of this century (2090 to 2099) for seven future scenarios developed for Phase 6 of the Coupled Model Intercomparison Project.

Understanding the spatial patterns of atmospheric ammonia trends in South Asia.

Ammonia (NH) is the most abundant alkaline gas in the atmosphere, mainly emitted by agricultural activities. NH readily reacts with other atmospheric acidic pollutants, such as the oxidation products of sulfur dioxide (SO) and nitrogen oxides (NOₓ), to create fine particulate matter, which has far-reaching effects on human health and ecosystems. Here, we investigated long-term atmospheric NH trends in South Asia (SA) using satellite observations from the Infrared Atmospheric Sounding Interferometer (IASI).

Sde proteins coordinate ubiquitin utilization and phosphoribosylation to establish and maintain the Legionella replication vacuole.

The Legionella pneumophila Sde family of translocated proteins promotes host tubular endoplasmic reticulum (ER) rearrangements that are tightly linked to phosphoribosyl-ubiquitin (pR-Ub) modification of Reticulon 4 (Rtn4). Sde proteins have two additional activities of unclear relevance to the infection process: K63 linkage-specific deubiquitination and phosphoribosyl modification of polyubiquitin (pR-Ub). We show here that the deubiquitination activity (DUB) stimulates ER rearrangements while pR-Ub protects the replication vacuole from cytosolic surveillance by autophagy.

Preclinical Evaluation of Sodium Butyrate's Potential to Reduce Alcohol Consumption: A Dose-Escalation Study in C57BL/6J Mice in Antibiotic-Enhanced Binge-Like Drinking Model.

Introduction: In our earlier efforts to establish gut-brain axis during alcohol use disorder (AUD), we have demonstrated that supplementation of C57BL/6J male mice with 8 mg/mL sodium butyrate, a major short-chain fatty acid, in drinking water reduced ethanol intake and neuroinflammatory response in antibiotic (ABX)-enhanced voluntary binge-like alcohol consumption model, drinking in the dark (DID).

Methods: To further evaluate the preclinical potential of SB, we have set a dose-escalation study in C57BL/6J male mice to test effects of ad libitum 20 mg/mL SB and 50 mg/mL SB and their combinations with ABX in the DID procedure for 4 weeks. Effects of these SB concentrations on ethanol consumption and bodily parameters were determined for the duration of the treatments.

To B or not to B: how the hepatitis B surveillance case definition can misdirect public health actions.

Surveillance case definitions are utilised to understand the epidemiology of communicable diseases and to inform public health actions. We report a case of hepatitis B infection that meets the case definition for newly acquired infection. However, further investigation revealed that this was most likely past resolved hepatitis B infection with subsequent reactivation secondary to immunosuppression, rather than a newly acquired infection.

Responses of fine particulate matter (PM) air quality to future climate, land use, and emission changes: Insights from modeling across shared socioeconomic pathways.

Air pollution induced by fine particulate matter with diameter ≤ 2.5 μm (PM) poses a significant challenge for global air quality management. Understanding how factors such as climate change, land use and land cover change (LULCC), and changing emissions interact to impact PM remains limited.
