NTHi killing activity is reduced in COPD patients and is associated with a differential microbiome.

Chronic obstructive pulmonary disease (COPD) is a chronic lung disease characterized by airway obstruction and inflammation. Non-typeable Haemophilus influenzae (NTHi) lung infections are common in COPD, promoting frequent exacerbations and accelerated lung function decline. The relationship with immune responses and NTHi are poorly understood.

Effect of intraoperative noise isolation on postoperative nausea and vomiting in patients undergoing gynecological laparoscopic surgery: protocol for a randomized controlled trial.

Background: Postoperative nausea and vomiting (PONV) are common complications following general anesthesia, particularly in gynecological laparoscopic surgeries. This study aims to evaluate the effect of intraoperative noise isolation on PONV incidence.

Method: This single-center, prospective, randomized controlled trial will enroll 192 adult patients undergoing laparoscopic gynecological surgery.

Comprehensive transcriptomic analysis reveals turnip mosaic virus infection and its aphid vector Myzus persicae cause large changes in gene regulatory networks and co-transcription of alternative spliced mRNAs in Arabidopsis thaliana.

Background: Virus infection and herbivory can alter the expression of stress-responsive genes in plants. This study employed high-throughput transcriptomic and alternative splicing analysis to understand the separate and combined impacts on host gene expression in Arabidopsis thaliana by Myzus persicae (green peach aphid), and turnip mosaic virus (TuMV).

Results: By investigating changes in transcript abundance, the data shows that aphids feeding on virus infected plants intensify the number of differentially expressed stress responsive genes compared to challenge by individual stressors.

Distinct Circle of Willis anatomical configurations in healthy preterm born adults: a 3D time-of-flight magnetic resonance angiography study.

Background: Preterm birth (< 37 weeks' gestation) alters cerebrovascular development due to the premature transition from a foetal to postnatal circulatory system, with potential implications for future cerebrovascular health. This study aims to explore potential differences in the Circle of Willis (CoW), a key arterial ring that perfuses the brain, of healthy adults born preterm.

Methods: A total of 255 participants (108 preterm, 147 full-term) were included in the analysis.

Non-targeted metabolomics reveals fatty acid and associated pathways driving resistance to whitefly and tomato leafminer in wild tomato accessions.

Wild tomato species exhibit natural insect resistance, yet the specific secondary metabolites and underlying mechanisms governing the resistance remain unclear. Moreover, defense expression dynamically adapts to insect herbivory, causing significant metabolic changes and species-specific secondary metabolite accumulation. The present study aims to identify the resistance-related metabolites in wild tomato accessions that influence the defense mechanism against whitefly (Bemisia tabaci Asia II 7) and leafminer (Phthorimaea absoluta).

Neonatal intermittent hypoxemia events are associated with later systemic hypertension.

Background: Approximately 5% of very premature infants delivered at less than 30 weeks' gestation have systemic hypertension. In adult human and animal models, intermittent hypoxemia events are associated with systemic hypertension. In neonates, intermittent hypoxemia events are associated with adverse outcomes, but it is unknown if they are a risk factor for hypertension.

Mitochondrial KMT9 methylates DLAT to control pyruvate dehydrogenase activity and prostate cancer growth.

Prostate cancer (PCa) growth depends on de novo lipogenesis controlled by the mitochondrial pyruvate dehydrogenase complex (PDC). In this study, we identify lysine methyltransferase (KMT)9 as a regulator of PDC activity. KMT9 is localized in mitochondria of PCa cells, but not in mitochondria of other tumor cell types.

Chronic kidney disease.

Chronic kidney disease (CKD) is defined by persistent abnormalities of kidney function or structure that have consequences for the health. A progressive decline of excretory kidney function has effects on body homeostasis. CKD is tightly associated with accelerated cardiovascular disease and severe infections, and with premature death.

Prevalence of hypertensive disorders of pregnancy and chronic hypertension increased throughout the COVID-19 pandemic in South Carolina (2015-2021).

Hypertensive disorders of pregnancy (HDP) and chronic hypertension (CHTN) are related to maternal and infant morbidity and mortality. We aimed to assess HDP and CHTN prevalence changes before (January 2015-February 2020) and during the COVID-19 pandemic (March 2020-December 2021) in South Carolina (SC). SC live births (2015-2021) were included (194,841 non-Hispanic White [NHW]); 108,195 non-Hispanic Black [NHB]; 25,560 Hispanic; 16,346 other race/ethnicity).

Upregulated FoxO1 promotes arrhythmogenesis in mice with heart failure and preserved ejection fraction.

Myocardial fibrosis leads to cardiac dysfunction and arrhythmias in heart failure with preserved ejection fraction (HFpEF), but the underlying mechanisms remain poorly understood. Here, RNA sequencing identifies Forkhead Box1 (FoxO1) signaling as abnormal in male HFpEF hearts. Genetic suppression of FoxO1 alters the intercellular communication between cardiomyocytes and fibroblasts, alleviates abnormal diastolic relaxation, and reduces arrhythmias.

Comparison of postoperative oxygenation in children receiving sugammadex versus neostigmine for reversal of neuromuscular blockade: a retrospective cohort study.

Purpose: Residual neuromuscular blockade can impair postoperative respiratory mechanics, promoting hypoxemia and pulmonary complications. Sugammadex, with its unique mechanism of action, may offer a more effective reversal of neuromuscular blockade and respiratory function than neostigmine. We sought to test the primary hypothesis that children undergoing noncardiac surgery exhibit better initial recovery oxygenation when administered sugammadex than those administered neostigmine.

Practical naloxone communication tips for pharmacists: Lessons learned from the Linguistic Model of Patient Participation in Care.

Background: Opioid overdose is an ongoing public health issue in the rural United States and can be countered by increasing access to the opioid antagonist naloxone. Community pharmacists are well-positioned to offer and dispense naloxone to patients at risk of opioid overdose, but still experience a range of communication barriers. Understanding rural patient communication preferences is essential to prepare pharmacists to discuss naloxone in a patient-centered manner.

Shared Use to Promote Physical Activity and Healthy Eating in Rural South Carolina United Methodist Churches: Opportunities and Pastor Beliefs.

Access to facilities that could promote physical activity (PA) and healthy eating (HE) is limited in rural areas. Shared use agreements with churches may be a promising strategy for enhancing rural community access to facilities. The goals of this qualitative study were to (a) examine rural pastors' views on the role of faith-based organizations in improving PA and HE in rural communities; (b) describe the availability of church facilities that could be used for PA and HE; (c) understand pastors' opinions on shared use of church facilities for community health promotion.

A proof-of-mechanism trial in asthma with lunsekimig, a bispecific nanobody® molecule.

Background: Monovalent biologics blocking thymic stromal lymphopoietin or interleukin-13 have been shown to elicit pharmacodynamic responses in asthma following a single dose. Therefore, dual blockade of these cytokines may result in an enhanced response compared to single targeting and has the potential to break efficacy ceilings in asthma. This study assessed the safety and tolerability of lunsekimig, a bispecific NANOBODY molecule that blocks thymic stromal lymphopoietin and interleukin-13, and its effect on Type 2 inflammatory biomarkers and lung function in asthma.

Vaccine efficacy of NVX-CoV2373 against SARS-CoV-2 infection in adolescents in the USA: an ancillary study to a phase 3, observer-blinded, randomised, placebo-controlled trial.

Background: Although existing COVID-19 vaccines are known to be highly effective against severe disease and death, data are needed to assess their ability to reduce SARS-CoV-2 infection. We aimed to estimate the efficacy of the NVX-CoV2373 protein subunit vaccine against SARS-CoV-2 infection, regardless of symptoms, among adolescents.

Methods: We performed an ancillary observational study (SNIFF) to the phase 3, observer-blinded, randomised, placebo-controlled PREVENT-19 trial that assessed vaccine efficacy against symptomatic COVID-19 in the USA.

Sustainable removal of gaseous Hg using sulfur functionalized biochar: Adsorption experiment and life cycle assessment.

Maximizing the sorption capacity of gaseous Hg by sulfur-functionalized biochar can lead to increased energy consumption and the production of secondary environmental pollutants such as greenhouse gases. This study evaluates the environmental impact of producing sulfurized biochar through a life cycle assessment (LCA), weighing these impacts against the benefits of enhanced Hg removal efficiencies. The biochar's Hg adsorption capacity, which ranges between 3 and 22 μg-Hg/g-biochar, is influenced by several factors: it increases with higher sulfur loading (0-15 %), higher O levels (0-21 %), and longer pyrolysis times (1-5 h).

Actinomycetes: Treasure trove for discovering novel antibiotic candidates.

Actinomycetes are an important source of secondary metabolites such as antibiotics and other active natural products. Many well-known antibiotics, such as streptomycin, oxytetracycline, and tetracycline, are produced by actinomycetes. Different types of antibiotics have distinct mechanisms of action against microorganisms: inhibit protein synthesis, inhibit nucleic acid synthesis, or inhibit cell wall synthesis.

Effect of postpartum oral furosemide use on postpartum readmissions and blood pressure trends.

Background: Oral furosemide postpartum improves the time to hypertension resolution in randomized control trials. Further investigation is needed to determine the impact of furosemide in routine clinical practice.

Objective: Real world study to assess impact of furosemide on rates of postpartum hypertension and readmissions for patients with hypertensive disorders of pregnancy.

Alemtuzumab and thrombotic thrombocytopenic purpura: Analysis of an international surveillance database and systematic literature review.

Objectives: Thrombotic thrombocytopenic purpura (TTP) is a thrombotic microangiopathy associated with severe deficiency in ADAMTS13. ADAMTS13 deficiency may be secondary to absent or dysfunctional protein production due to mutations in the ADAMTS13 gene (congenital TTP) or autoantibody-mediated clearance and/or inhibition (immune-mediated TTP). This autoimmunity may, albeit rarely, occur secondary to certain medications (eg, ticlopidine).

A Phase 3B, Open-Label Study to Evaluate the Immunogenicity and Safety of the Quadrivalent Meningococcal Nimenrix Vaccine When Given to Healthy Infants at 3 and 12 Months of Age.

Introduction: Infants and young children typically have the highest age-related risk of invasive meningococcal disease. The immunogenicity and safety of a single primary dose and a booster of a meningococcal A/C/W/Y tetanus toxoid conjugate vaccine (MenACWY-TT; Nimenrix) in infants were evaluated.

Methods: In this phase 3b, open-label, single-arm study, healthy 3-month-old infants received a single Nimenrix dose followed by a booster at age 12 months (1 + 1 series).

The impact of a secondary, rare, non-pathogenic PKD1 variant on disease progression in autosomal dominant polycystic kidney disease.

Background: Autosomal dominant polycystic kidney disease (ADPKD) is caused primarily by pathogenic variants in the PKD1 and PKD2 genes. Although the type of ADPKD variant can influence disease severity, rare, hypomorphic PKD1 variants have also been reported to modify disease severity or cause biallelic ADPKD. This study examines whether rare, additional, potentially protein-altering, non-pathogenic PKD1 variants contribute to ADPKD phenotypic outcomes.

Past and future in vitro and in vivo approaches toward circulating factors and biomarkers in idiopathic nephrotic syndrome.

Predicting the risks of progression to chronic kidney disease (CKD) stage 5 in idiopathic nephrotic syndrome (NS) and recurrence of the disease (rNS) following kidney transplantation (KT) is a key assessment to provide essential management information. NS has been categorized etiologically as genetic and immune-based. A genetic cause can be identified in ~ 30% of children with steroid-resistant NS (SRNS), a finding associated with a very low risk of rNS following KT.

Infection-Related Hospitalization and Incident Heart Failure: The Atherosclerosis Risk in Communities Study.

Background: The immune response to infections may become dysregulated and promote myocardial damage contributing to heart failure (HF). We examined the relationship between infection-related hospitalization (IRH) and HF, HF with preserved ejection fraction, and HF with reduced ejection fraction.

Methods And Results: We studied 14 468 adults aged 45 to 64 years in the ARIC (Atherosclerosis Risk in Communities) Study who were HF free at visit 1 (1987-1989).
