Microbiome-animal host symbioses are ubiquitous in nature. Animal-associated microbiomes can play a crucial role in host physiology, health and resilience to environmental stressors. As climate change drives rising global temperatures and increases the frequency of thermal extremes, microbiomes are emerging as a new frontier in buffering vulnerable animals against temperature fluctuations.

Importance: Using albumin-adjusted calcium is commonly recommended for for measuring calcium, but with little empirical evidence to support the practice.
Objective: To assess the correlation between total calcium measurements (with or without adjustment) vs the ionized calcium level as a reference standard.
Design, Setting, And Participants: This was a population-based cross-sectional study in the province of Alberta, Canada, including adults tested for serum total calcium and ionized calcium simultaneously between January 1, 2013, and October 31, 2019.

Importance: Secondary lymphedema is a common, harmful side effect of breast cancer treatment. Robust risk models that are externally validated are needed to facilitate clinical translation. A published risk model used 5 accessible clinical factors to predict the development of breast cancer-related lymphedema; this model included a patient's mammographic breast density as a novel predictive factor.

Importance: Detection of congenital cytomegalovirus (cCMV) infection has previously relied on targeted screening programs or clinical recognition; however, these approaches miss most cCMV-infected newborns and fail to identify those infants who are asymptomatic at birth but at risk for late-onset sensorineural hearing loss.
Objective: To determine the feasibility of using routinely collected newborn dried blood spots (DBS) in a population-based cCMV screen to identify infants at risk for hearing loss and describe outcomes of infants screened.
Design, Setting, And Participants: This diagnostic study of a population-based screening program in Ontario, Canada, took place from July 29, 2019, to July 31, 2023.

Purpose: Mesothelin (MSLN) is highly expressed in high grade serous/ endometrioid ovarian cancers (HGOC). Anetumab ravtansine (AR) is an antibody drug conjugate directed at MSLN antigen with a tubulin polymerization inhibitor. We assessed safety, activity and pharmacokinetics of the combination AR/bevacizumab (Bev) (ARB) versus weekly paclitaxel (wP)/Bev (PB) in patients with platinum resistant/refractory HGOC (prrHGOC).

Bats have adapted to pathogens through diverse mechanisms, including increased resistance - rapid pathogen elimination, and tolerance - limiting tissue damage following infection. In the Egyptian fruit bat (an important model in comparative immunology) several mechanisms conferring disease tolerance were discovered, but mechanisms underpinning resistance remain poorly understood. Previous studies on other species suggested that elevated basal expression of innate immune genes may lead to increased resistance to infection.

Purpose: Head acceleration events (HAEs) are a growing concern in contact sports, prompting two rugby governing bodies to mandate instrumented mouthguards (iMGs). This has resulted in an influx of data imposing financial and time constraints. This study presents two computational methods that leverage a dataset of video-coded match events: cross-correlation synchronisation aligns iMG data to a video recording, by providing playback timestamps for each HAE, enabling analysts to locate them in video footage; and post-synchronisation event matching identifies the coded match event (e.

Loneliness, social isolation, and living alone are significant risk factors for mortality, particularly in older adults. This systematic review and meta-analysis aimed to quantify their associations with all-cause and cause-specific mortality in older adults, broadening previous research by including more social factors. Comprehensive searches were conducted in PubMed, APA PsycINFO, and CINAHL until December 31, 2023, following PRISMA 2020 and MOOSE guidelines.

The duration of mechanical systole-also termed the flow time (FT) or left ventricular ejection time (LVET)-is measured by Doppler ultrasound and increasingly used as a stroke volume (SV) surrogate to guide patient care. Nevertheless, confusion exists as to the determinants of FT and a critical evaluation of this measure is needed. Using Doppler ultrasound of the left ventricular outflow tract velocity time integral (LVOT VTI) as well as strain and strain rate echocardiography as grounding principles, this brief commentary offers a model for the independent influences of FT.

Rationale: In critically ill patients receiving invasive mechanical ventilation, switching from controlled to assisted ventilation is a crucial milestone towards ventilator liberation. The optimal timing for switching to assisted ventilation has not been studied.
Objectives: Our objective was to determine whether a strategy of early as compared to delayed switching affects the duration of invasive mechanical ventilation, ICU length of stay, and mortality.

Many prokaryotic and eukaryotic cells store inorganic phosphate in the form of polymers called polyphosphate (polyP). There has been an explosion of interest in polyP over the past decade, in part due to newly suggested roles related to diverse aspects of human health. The physical interaction of polyP chains with specific proteins has been proposed to regulate cellular homeostasis and modulate signaling pathways in response to environmental changes.

Despite advances in solid phase peptide synthesis and peptide ligation, challenges remain in the assembly of polypeptides through coupling of peptide fragments. Herein we describe a new method for peptide fragment coupling employing the Ag(I)-promoted transformation of peptide thioamides. This process proceeds an isoimide-tethered intermediate, which undergoes an O-N acyl transfer to generate the polypeptide.

The American Association for the Surgery of Trauma initially published the organ injury scaling for the kidney in 1989, which was subsequently updated in 2018. This current American Association for the Surgery of Trauma kidney organ injury scaling update incorporates the latest evidence in diagnosis and management of renal trauma and is based upon a multidisciplinary consensus. These changes reflect the near universal use of computed tomography for renal trauma evaluation and the widespread adoption of conservative management across all grades of renal trauma.

Background Indeterminate focal liver observations in patients at risk for hepatocellular carcinoma (HCC) may require invasive biopsy or follow-up, which could lead to delays in definitive categorization and to postponement of treatment. Purpose To examine clinical effect of contrast-enhanced US (CEUS) in participants with high-risk indeterminate liver observations categorized as Liver Imaging Reporting and Data System (LI-RADS) category LR-4 (probably HCC) or LI-RADS category LR-M (probably or definitely malignant but not HCC specific) at CT or MRI. Materials and Methods This was a secondary analysis of a prospective international multicenter validation study for CEUS LI-RADS (January 2018 to August 2021).
