Perspective: Enteric methane mitigation and its impact on livestock hydrogen emissions.

In a hydrogen-based economy future, hydrogen leakage is becoming an environmental concern. Ruminants naturally produce small amounts of hydrogen, which is emitted in the environment along with other fermentation gases, such as the GHG methane and carbon dioxide. Here, for the first time, we estimated hydrogen emissions from the global ruminant livestock at 527 kt/yr (95% CI: 399, 654), or about 3.

Low-added sugar dietary intervention study to mitigate glucose intolerance and improve body composition in adults with cystic fibrosis: a protocol of a double-blind, randomised study.

Introduction: People with cystic fibrosis (PwCF) are at high risk for developing cystic fibrosis (CF)-related diabetes (CFRD), which worsens morbidity and mortality. Although the pathological events leading to the development of CFRD are complex and not completely understood, dietary factors may play a role. For example, habitual intake of dietary added sugar (i.

Individual-, Hospital-, And Community-Level Factors Associated With Sudden Unexpected Infant Death Among Infants Born Preterm in 5 US States.

Objective: To investigate individual-, hospital-, and community-level factors associated with sudden unexpected infant death (SUID) among infants born preterm.

Study Design: The following linked dataset from 5 states (California, Michigan, Oregon, Pennsylvania, and South Carolina) from 2005 through 2020 was used: 1) infant birth and death certificates; 2) maternal and infant birth hospitalization discharge records; 3) birthing hospital data from the American Hospital Association; and 4) community-level data from the Social Vulnerability Index (SVI).) Multivariable models were used to assess the independent association between these multi-level factors and SUID, adjusting for several maternal and infant characteristics.

Complement activation as a biomarker for platelet activating antibodies in heparin-induced thrombocytopenia (HIT).

Background: IgG antibodies (Abs) to platelet factor 4 complexed to heparin (PF4/H) commonly occur after heparin exposure but cause life-threatening complications of heparin-induced thrombocytopenia (HIT) in only a few patients. Presently, only platelet activation assays reliably distinguish anti-PF4/H Abs that cause disease (HIT Abs) from those likely to be asymptomatic (AAbs).

Objectives: Recent studies indicate that complement activation is an important serologic property of HIT Abs and is essential for FcγRIIA-mediated cellular activation.

Impact of Kidney Allocation System 250 Policy on One Year Graft Loss.

A new deceased donor kidney allocation system (KAS250) was implemented in March 2021 that prioritizes recipients within a 250 nautical mile radius from the donor hospital. KAS250 was implemented to reduce geographic disparities in access to kidney transplantation. Studies have shown an increase in cold ischemia time (CIT) after KAS250 implementation but the impact on graft outcomes is unknown.

A Mechanistic Approach to Optimize Combination Antibiotic Therapy.

Antimicrobial resistance is one of the most significant healthcare challenges of our times. Multidrug or combination therapies are sometimes required to treat severe infections; for example, the current protocols to treat pulmonary tuberculosis combine several antibiotics. However, combination therapy is usually based on lengthy empirical trials, and it is difficult to predict its efficacy.

Interplay between on-demand treatment trials for hereditary angioedema and treatment guidelines.

Over the past two decades, guidelines for the on-demand treatment of hereditary angioedema (HAE) attacks have undergone significant evolution. Early treatment guidelines, such as the Canadian 2003 International Consensus Algorithm, often gated on-demand treatment by attack location and/or severity. Pivotal trials for on-demand injectable treatments (plasma-derived C1 esterase inhibitor [C1INH], icatibant, ecallantide [US only], recombinant C1INH), which were approved in the US and EU between 2008-2014, were designed accordingly.

Exploring the druggability of the UEV domain of human TSG101 in search for broad-spectrum antivirals.

The ubiquitin E2 variant domain of TSG101 (TSG101-UEV) plays a pivotal role in protein sorting and virus budding by recognizing PTAP motifs within ubiquitinated proteins. Disruption of TSG101-UEV/PTAP interactions has emerged as a promising strategy for the development of host-oriented broad-spectrum antivirals with low susceptibility to resistance. TSG101 is a challenging target characterized by an extended and flat binding interface, low affinity for PTAP ligands, and complex binding energetics.

Private-Sector Readmissions for Inpatient Surgery in Veterans Health Administration Hospitals.

Importance: The Veterans Health Administration (VHA) reports multiple indicators of hospital surgical performance, including hospital risk-standardized 30-day readmission rates (RSRRs). Currently, most routinely reported measures do not include readmissions that occur outside VHA hospitals. The impact of readmissions outside the VHA on hospital RSRR is not known.

Persistent Short Sleep Duration From Pregnancy to 2 to 7 Years After Delivery and Metabolic Health.

Importance: Short sleep duration during pregnancy and the perimenopausal period has been associated with adverse cardiometabolic outcomes. However, it remains unclear how sleep duration changes after delivery and whether such changes are associated with the cardiometabolic health of birthing people.

Objective: To investigate whether persistently short sleep during pregnancy and after delivery is associated with incident hypertension and metabolic syndrome.

Clinician Perspectives on the Management of Hearing Loss in Patients With Limited English Proficiency.

Objective: Clinicians face challenges in managing the growing population of patients with limited English proficiency (LEP) and hearing loss (HL) in the United States. This study seeks to investigate provider perspectives on evaluating, counseling, and treating HL in LEP patients.

Study Design: Prospective descriptive study.

Surrogate Wars: The "Best Interest Values" Hierarchy & End-of-Life Conflicts with Surrogate Decision-Makers.

Conflicts involving end-of-life care between healthcare providers (HCPs) and surrogate decision-makers (SDMs) have received sustained attention for more than a quarter of a century, with early studies demonstrating a frequency of HCP-SDM conflict in ICUs ranging from 32-78% of all admissions (Abbott et al. 2001; Breen et al. 2001; Studdert et al.

Comparative bioacoustics of multiple eastern versus western songbird pairs in North America reveals a gradient of song divergence.

Vocalizations are one of the key premating reproductive barriers that could affect species formation. In song-learning birds, vocal traits are sometimes overlooked in species delimitation, as compared to morphological or plumage-based differences. In this study, we assessed geographic variation in songs of eight pairs of oscines on two scales: (1) comparing primary songs of species/subspecies pairs whose breeding grounds are eastern and western counterparts of each other in the continental North America, and (2) for each counterpart, identifying and comparing possible variation among their populations.

Extending the Environmental influences on Child Health Outcomes (ECHO) Cohort through 2030: Rationale and study protocol.

Early life environmental exposures, even those experienced before conception, can shape health and disease trajectories across the lifespan. Optimizing the detection of the constellation of exposure effects on a broad range of child health outcomes across development requires considerable sample size, transdisciplinary expertise, and developmentally sensitive and dimensional measurement. To address this, the National Institutes of Health (NIH) Environmental influences on Child Health Outcomes (ECHO) Cohort Study is an observational longitudinal pediatric cohort study.

A Community-Engaged, Mixed-Methods Approach to Prioritizing Needs in a Statewide Assessment of Community Cancer Needs.

Introduction: Kentucky has the highest all-site cancer incidence and death rate in the US. In 2021, the University of Kentucky Markey Cancer Center convened a steering committee to conduct a statewide community cancer needs assessment (CNA). The goal of the final CNA phase was to gather community input on prioritizing Kentucky's cancer-related needs and ways to address them.

Genome evolution following an ecological shift in nectar-dwelling .

Unlabelled: The bacterial genus includes species found in environmental habitats like soil and water, as well as taxa adapted to be host-associated or pathogenic. High genetic diversity may allow for this habitat flexibility, but the specific genes underlying switches between habitats are poorly understood. One lineage of has undergone a substantial habitat change by evolving from a presumed soil-dwelling ancestral state to thrive in floral nectar.
