High and low performing sires differ in their contributions to early embryonic stress in the bovine.

Context Sires differ in their ability to produce viable blastocysts, yet our understanding of the cellular mechanisms regulated by the sire during early embryo development is limited. Aims The first aim was to characterise autophagy and reactive oxygen species (ROS) in embryos produced by high and low performing sires under normal and stress culture conditions. The second aim was to evaluate DNA damage and lipid peroxidation as mechanisms that may be impacted by increased cellular stress, specifically oxidative stress.

Osteosarcoma with widespread metastasis in a 1-year-old crossbred rabbit.

A 14-month-old female spayed, small crossbred rabbit presented for assessment of a small, hard subcutaneous nodule in the right axilla. Serum biochemistry showed markedly increased serum ALP activity. A whole-body CT revealed an aggressive, monostotic osteolytic, and productive lesion within the left alveolar process of the maxilla, with erosion of the alveolar bone and secondary premolar depression.

Did the health care vaccine mandate work? An evaluation of the impact of the COVID-19 vaccine mandate on vaccine uptake and infection risk in a large cohort of Canadian health care workers.

Background: We aimed to evaluate the impact of health care vaccine mandates on vaccine uptake and infection risk in a cohort of Canadian health care workers (HCWs).

Methods: We conduct interrupted time series analysis through a regression discontinuity in time approach to estimate the immediate and delayed impact of the mandate. Multilevel mixed effect modeling fitted with restricted maximum likelihood was used to estimate impact on infection risk.

Are COVID-19 vaccination mandates for healthcare workers effective? A systematic review of the impact of mandates on increasing vaccination, alleviating staff shortages and decreasing staff illness.

Introduction: The rapid development of COVID-19 vaccines is a cornerstone in the global effort to combat the pandemic. Healthcare workers (HCWs), being at the forefront of the pandemic response, have been the focus of vaccine mandate policies. This review aims to evaluate the impacts of COVID-19 vaccine mandates among HCWs, a critical step in understanding the broader implications of such policies in healthcare settings.

Systematizing Information Use to Address Determinants of Health Worker Health in South Africa: A Cross-sectional Mixed Method Study.

Background: Recognizing that access to safe and healthy working conditions is a human right, the World Health Organization (WHO) calls for specific occupational safety and health (OSH) programs for health workers (HWs). The WHO health systems' building blocks, and the International Labour Organization (ILO), highlight the importance of information as part of effective systems. This study examined how OSH stakeholders access, use, and value an occupational health information system (OHIS).

Paternal determinants of early embryo development.

Existing research has primarily focused on investigating the impacts of the maternal environment, female fertility phenotype, and genetics on pregnancy loss in dairy cattle. Recently, attention has been directed toward understanding the role the sire has on embryo quality and viability. Studies have shown there is a paternal influence on early pregnancy loss, but the specific mechanisms impacting pregnancy establishment and maintenance remain unclear.

Evaluation of MV140 in preventing recurrent urinary tract infections: a multicentre double-blind randomized controlled trial protocol.

Objectives: To determine, firstly, whether MV140 reduces rates of recurrent urinary tract infections (rUTIs) in patients older than 65 years, measured as the number of urinary tract infections (UTIs) detected over 12 months following the completion of a 3-month treatment course and, additionally, to assess the number of re-admissions to the emergency department, the rate of antibiotic use for UTIs, the safety profile of MV140, and quality of life.

Materials And Methods: This is a multicentre, double-blind, randomized controlled trial with two arms. Patients will be randomized and allocated to receive either a 3-month course of MV140 or placebo (two sublingual sprays daily).

Impact of Sire on Embryo Development and Pregnancy.

The use of in vitro embryo production (IVP) has increased globally, particularly in the United States. Although maternal factors influencing embryo development have been extensively studied, the influence of the sire is not well understood. Sperm plays a crucial role in embryo development providing DNA, triggering oocyte maturation, and aiding in mitosis.

Sire modulates developmental kinetics and transcriptome of the bovine embryo.

In Brief: The first week of gestation is a period of major pregnancy loss in cattle, this study reveals that the male plays a key role in regulating embryonic development during this time.

Abstract: The impact of sire on preimplantation embryonic development in cattle remains poorly understood. This study evaluated differences in embryos produced in vitro from sires with varying capacities to produce blastocysts.

Vaccination, time lost from work, and COVID-19 infections: a Canadian healthcare worker retrospective cohort study.

The COVID-19 pandemic highlighted hurdles for healthcare delivery and personnel globally. Vaccination has been an important tool for preventing severe illness and death in healthcare workers (HCWs) as well as the public at large. However, vaccination has resulted in some HCWs requiring time off work post-vaccination to recover from adverse events.

Urology case report - Emergency penectomy for the transfeminine patient.

Management of gender dysphoria and healthcare for transgender and non-binary patients is a growing field in Australia and abroad. Currently, gender-affirming surgery is not offered under Australia's national public health insurance. We present an unusual case of emergency penectomy required for a 57-year-old woman assigned-male-at-birth from rural Australia after a self-inflicted chemical burn.

Young children can infer information preferences from goals and recommend appropriate sources to others.

As adults, we intuitively understand how others' goals influence their information-seeking preferences. For example, you might recommend a dense book full of mechanistic details to someone trying to learn about a topic in-depth, but a more lighthearted book filled with surprising stories to someone seeking entertainment. Moreover, you might do this with confidence despite knowing few details about either book.

Survival benefits with EPIC in addition to HIPEC for low grade appendiceal neoplasms with pseudomyxoma peritonei: a propensity score matched study.

Objectives: Appendiceal cancer is a rare malignancy, occurring in roughly 1.2 per 100,000 per year. Low grade appendiceal neoplasams (LAMN) in particular can lead to pseudomyxoma peritonei (PMP), and respond poorly to systemic chemotherapy.

Urban-rural divide in COVID-19 infection and vaccination rates in healthcare workers in British Columbia, Canada.

Introduction: Healthcare workers (HCWs) play a critical role in responding to the COVID-19 pandemic. Early in the pandemic, urban centres were hit hardest globally; rural areas gradually became more impacted. We compared COVID-19 infection and vaccine uptake in HCWs living in urban versus rural locations within, and between, two health regions in British Columbia (BC), Canada.

Protecting healthcare workers during a pandemic: what can a WHO collaborating centre research partnership contribute?

Objectives: To ascertain whether and how working as a partnership of two World Health Organization collaborating centres (WHOCCs), based respectively in the Global North and Global South, can add insights on "what works to protect healthcare workers (HCWs) during a pandemic, in what contexts, using what mechanism, to achieve what outcome".

Methods: A realist synthesis of seven projects in this research program was carried out to characterize context (C) (including researcher positionality), mechanism (M) (including service relationships) and outcome (O) in each project. An assessment was then conducted of the role of the WHOCC partnership in each study and overall.

Playground injury prevention: the need for consistent and national implementation of Australian safety standards.

Objectives: Hospitalisation rates for injury, including at playgrounds, have not changed in the past decade. There are nine Australian Standards specific to playgrounds. The impact (if any) of these standards on playground injury resulting in hospitalisation is unknown.

A Path Toward Equity and Inclusion: Establishing a DEI Committee in a Department of Pediatrics.

The Diversity, Equity, and Inclusion (DEI) committee was established in 2017 within the Department of Pediatrics at Rush University Medical Center (RUMC), an academic medical health center located on the near west side of Chicago, IL. Results from climate surveys highlighted the need for increased DEI initiatives within the department, and a renewed national reckoning on racial tensions sparked an additional sense of urgency for system-level change. This paper outlines the initial creation and ongoing efforts of the DEI committee.

Using natural language processing in facilitating pre-hospital telephone triage of emergency calls.

Introduction: Natural language processing (NLP) is an area of computer science that involves the use of computers to understand human language and semantics (meaning) and to offer consistent and reliable responses. There is good evidence of significant advancement in the use of NLP technology in dealing with acutely ill patients in hospital (such as differential diagnosis assistance, clinical decision-making and treatment options). Further technical development and research into the use of NLP could enable further improvements in the quality of pre-hospital emergency care.

Truncation of IFT80 causes early embryonic loss in Holstein cattle associated with Holstein haplotype 2.

Recessive alleles represent genetic risk in populations that have undergone bottleneck events. We present a comprehensive framework for identification and validation of these genetic defects, including haplotype-based detection, variant selection from sequence data, and validation using knockout embryos. Holstein haplotype 2 (HH2), which causes embryonic death, was used to demonstrate the approach.
