Undoped ruthenium oxide as a stable catalyst for the acidic oxygen evolution reaction.

Reducing green hydrogen production cost is critical for its widespread application. Proton-exchange-membrane water electrolyzers are among the most promising technologies, and significant research has been focused on developing more active, durable, and cost-effective catalysts to replace expensive iridium in the anode. Ruthenium oxide is a leading alternative while its stability is inadequate.

Patterns of Klebsiella pneumoniae bacteremic dissemination from the lung.

Bacteremia, a leading cause of death, generally arises after bacteria establish infection in a particular tissue and transit to secondary sites. Studying dissemination from primary sites by solely measuring bacterial burdens does not capture the movement of individual clones. By barcoding Klebsiella pneumoniae, a leading cause of bacteremia, we track pathogen dissemination following pneumonia.

Postoperative Outcomes Following Lung Resection Performed at Private Equity-Acquired Hospitals.

Objective: Private equity acquisition of hospitals performing complex operations is increasingly prevalent in the United States healthcare landscape. While comparative health outcomes for common medical conditions have been investigated, the quality of thoracic surgical care in private equity-acquired hospitals is unknown.

Methods: Medicare Beneficiaries, aged 65-99 years, undergoing elective lung resection between 2016 to 2020 were included.

Objective: To compare sex and racial differences in 180-day infection rates after coronary artery bypass grafting (CABG) and aortic valve replacement (AVR).

Methods: A Statewide Society of Thoracic Surgeons Adult Cardiac Surgery Database was linked to Medicare claims data to identify 8,887 beneficiaries undergoing CABG and AVR (surgical or transcatheter) between 2017 and 2021. The primary outcome was the incidence of 180-day infection.

The histamine pathway is a target to treat hepatic experimental erythropoietic protoporphyria.

Background & Aims: Erythropoietic protoporphyria (EPP) is caused by mutations in ferrochelatase which inserts iron into protoporphyrin-IX (PP-IX) to generate heme. EPP is characterized by PP-IX accumulation, skin photosensitivity, cholestasis, and end-stage liver disease. Despite available drugs that address photosensitivity, treatment of EPP-related liver disease remains an unmet need.

Outcomes after medical treatment for primary aldosteronism: an international consensus and analysis of treatment response in an international cohort.

Background: Primary aldosteronism can be treated medically but there is no standardised method to evaluate treatment outcomes. We aimed to develop criteria for assessing the outcomes of targeted medical treatment of primary aldosteronism, analyse outcomes across an international cohort, and identify factors associated with a complete treatment response.

Methods: An international panel of 31 primary aldosteronism experts used the Delphi method to reach consensus on the definition of complete, partial, or absent biochemical and clinical outcomes of medical treatment of primary aldosteronism.

Discovery of a DNA methylation profile in individuals with Sifrim-Hitz-Weiss syndrome.

Pathogenic heterozygous variants in CHD4 cause Sifrim-Hitz-Weiss syndrome, a neurodevelopmental disorder associated with brain anomalies, heart defects, macrocephaly, hypogonadism, and additional features with variable expressivity. Most individuals have non-recurrent missense variants, complicating variant interpretation. A few were reported with truncating variants, and their role in disease is unclear.

Gender disparities in industry payments to neurosurgeons: a comprehensive analysis of Centers for Medicare & Medicaid Services Open Payments data (2016-2022).

Objective: This study aimed to investigate the extent of gender disparities in financial interactions between neurosurgeons and the medical device industry, examining the differences in the number, amount, and types of payments made to male and female neurosurgeons.

Methods: Utilizing data from the Centers for Medicare & Medicaid Services Open Payments database covering 2016-2022, the authors conducted a comprehensive analysis of industry payments to neurosurgeons. This methodology included univariate and multivariate analyses to examine the disparities in payments, with a focus on identifying significant differences in compensation across genders.

Deficient neutrophil responses early in influenza infection promote viral replication and pulmonary inflammation.

Neutrophils play key protective roles in influenza infections, yet excessive neutrophilic inflammation is a hallmark of acute lung injury during severe infections. Phenotypic heterogeneity is increasingly recognized in neutrophil populations; however, how functional variation in neutrophils between individuals determine the diverse outcomes of influenza remains unclear. To examine immunologic responses that may drive varying outcomes in influenza, we infected C57BL/6 (B6) and A/J mice with mouse-adapted influenza A virus A/PR/8/34 H1N1.

Workload-capacity imbalances and their impact on self-management complexity in patients with multimorbidity: a multicenter cross-sectional study.

Introduction: Multimorbidity is increasing globally, emphasizing the need for effective self-management strategies. The Cumulative Complexity Model (CuCoM) offers a unique perspective on understanding self-management based on workload and capacity. This study aims to validate the CuCoM in multimorbid patients and identify tailored predictors of self-management.

Leucine-rich alpha-2 glycoprotein in combination with C-reactive protein for predicting endoscopic activity in Crohn's disease: a single-centre, cross-sectional study.

Background And Objective: Leucine-rich alpha-2 glycoprotein (LRG) is a novel biomarker for Crohn's disease (CD). The utility of combination use of LRG and C-reactive protein (CRP) has not been reported. This study aimed to investigate the diagnostic performance of LRG in combination with CRP to predict endoscopic activity.

Risk-based triage strategy by extended HPV genotyping for women with ASC-US cytology.

Objective: We attempted to evaluate the immediate high-grade squamous intraepithelial lesion-cervical intraepithelial neoplasia grade 2/3 or worse (HSIL-CIN2+/3+, hereafter referred to as CIN2+/3+) risk of specific human papillomavirus (HPV) genotype and form the precise risk-based triage strategy for atypical squamous cells of undetermined significance (ASC-US) women.

Methods: The clinical data of ASC-US women who underwent HPV genotyping testing and colposcopy were retrospectively reviewed. The distribution and CIN2+/3+ risks of specific HPV genotype were assessed by three approaches.

Tear neuropeptides are associated with clinical symptoms and signs of dry eye patients.

Purpose: To evaluate levels of 3 tear-soluble neuropeptides in dry eye patients and to identify the correlations with clinical signs and symptoms.

Methods: A total of 16 dry eye patients and 12 healthy volunteers were enrolled. Dry eye disease (DED) diagnosis was based on the 2017 Report of the Tear Film & Ocular Surface Society International Dry Eye Workshop (TFOS DEWS II).

Similar Conditions With Opposite Effects: Predation-Risk Effects on Prey Abundance Are Highly Contingent.

Experiments have shown that predation-risk effects on prey fitness can be highly contingent on environmental conditions, suggesting a potential difficulty in generalizing risk effects on prey abundance in natural settings. Rather than study the influence of a particular controlled factor, we examine the problem with a novel approach. We examined the influence of risk effects in multiple experiments performed under similar study conditions.
