Tele-Ultrasound in the Wilderness: A Tutorial Experience for Medical Students.

Introduction: Providers can evaluate patients who sustain trauma during outdoor activities by using the extended focused assessment with sonography for trauma (FAST) and the limited knee ultrasound. Remote tele-mentored ultrasound (RTMUS) can help minimally trained providers in the wilderness if they have difficulty obtaining a view or have questions about the interpretation of an image. The goal of our study was to determine the feasibility of using RTMUS to teach the FAST exam and knee ultrasound exam to ultrasound-naive medical students during a wilderness medicine outdoor activity.

Development and Implementation of a Multicenter Registry for Resuscitation-Focused Transesophageal Echocardiography.

Study Objective: To evaluate the clinical effect, safety, and clinical outcomes of focused transesophageal echocardiography (TEE) in the evaluation of critically ill patients in the emergency department (ED) and ICUs.

Methods: We established a prospective, multicenter, observational registry involving adult critically ill patients in whom focused TEE was performed for evaluation of out-of-hospital cardiac arrest (OHCA), inhospital cardiac arrest, evaluation of undifferentiated shock, hemodynamic monitoring, and/or procedural guidance in the ED, ICU, or operating room setting. The primary objective of the current investigation was to evaluate the clinical influence and safety of focused, point-of-care TEE in critically ill patients.

Association of microbial community structure with gill disease in marine-stage farmed Atlantic salmon (Salmo salar); a yearlong study.

Background: Understanding the relationship between resident microbiota and disease in cultured fish represents an important and emerging area of study. Marine gill disorders in particular are considered an important challenge to Atlantic salmon (Salmo salar) aquaculture, however relatively little is known regarding the role resident gill microbiota might play in providing protection from or potentiating different gill diseases. Here, 16S rRNA sequencing was used to examine the gill microbiome alongside fish health screening in farmed Atlantic salmon.

Gender bias in video game dialogue.

Gender biases in fictional dialogue are well documented in many media. In film, television and books, female characters tend to talk less than male characters, talk to each other less than male characters talk to each other, and have a more limited range of things to say. Identifying these biases is an important step towards addressing them.

On Bender's orientation to models: Towards a philosophical debate on covering laws, theory, emergence and mechanisms in nursing science.

Nursing scholars continuously refine nursing knowledge and the philosophical foundations of nursing practice. They advance nursing knowledge by creating new knowledge and weighing the relevance of developments in cognate sciences. Nurse philosophers go further by providing epistemological and ontological arguments for explanations of nursing phenomena.

Avian Sex Determination: A Chicken and Egg Conundrum.

Background: Primary sex determination is the developmental process that results in the sexual differentiation of the gonads. Vertebrate sex determination is generally considered to follow the model based on the mammalian system, where a sex-specific master regulatory gene activates one of the two different gene networks that underlie testis and ovary differentiation.

Summary: It is now known that, while many of the molecular components of these pathways are conserved across different vertebrates, a wide variety of different trigger factors are utilized to initiate primary sex determination.

Transformational leadership and predictors of resilience among registered nurses: a cross-sectional survey in an underserved area.

Background: High resilience increases nurses' ability to cope with job-related stressors and enhances job satisfaction and, consequently, their retention. The study aims to identify resilience predictors and perceptions of transformational leadership in a convenience sample of registered nurses in Lebanon.

Methods: An anonymous cross-sectional survey of a convenience sample of 240 registered nurses working for more than a year at three private hospitals in an underserved area in South Lebanon was used.

Changes in Bone Mineral Density and Serum Lipids across the First Postpartum Year: Effect of Aerobic Fitness and Physical Activity.

This study evaluated the changes in bone mineral density (BMD) and serum lipids across the first postpartum year in lactating women compared to never-pregnant controls, and the influence of physical activity (PA). The study also explored whether N-telopeptides, pyridinoline, and deoxypyridinoline in urine serve as biomarkers of bone resorption. A cohort of 18 initially lactating postpartum women and 16 never pregnant controls were studied.

Determining levels of nurse burnout during the COVID-19 pandemic and Lebanon's political and financial collapse.

Background: The COVID-19 pandemic compounded political and financial pressures on the nursing workforce in Lebanon. The government resigned in October 2019 in response to the popular uprising that called for an end to corruption and economic mismanagement 5 months before the first COVID-19 case appeared in the country. The continuing crises and the added stress of COVID-19 has increased the risk of occupational burnout and turnover in the nursing workforce.

Gill Transcriptomic Responses to Toxin-producing Alga in Rainbow Trout.

The gill of teleost fish is a multifunctional organ involved in many physiological processes, including protection of the mucosal gill surface against pathogens and other environmental antigens by the gill-associated lymphoid tissue (GIALT). Climate change associated phenomena, such as increasing frequency and magnitude of harmful algal blooms (HABs) put extra strain on gill function, contributing to enhanced fish mortality and fish kills. However, the molecular basis of the HAB-induced gill injury remains largely unknown due to the lack of high-throughput transcriptomic studies performed on teleost fish in laboratory conditions.

Employer-Sponsored Benefits in the United States: The Past, Present, and Future.

In early 2020, the COVID-19 virus caused a global pandemic, threatening the lives and livelihoods of millions across the globe. As of this writing, 40 million Americans had filed first-time unemployment claims U.S.

Sampling the fish gill microbiome: a comparison of tissue biopsies and swabs.

Background: Understanding the influence of methodology on results is an essential consideration in experimental design. In the expanding field of fish microbiology, many best practices and targeted techniques remain to be refined. This study aimed to compare microbial assemblages obtained from Atlantic salmon (Salmo salar) gills by swabbing versus biopsy excision.

Factors Associated With the Resilience of Nurses During the COVID-19 Pandemic.

Background: The delivery of health care during the COVID-19 outbreak imposed significant challenges on the global nursing workforce and placed them at a higher risk of occupational burnout and turnover. In Lebanon, the pandemic hit when nurses were already struggling with an economic collapse caused by government failures. Resilience may play a protective factor against adversity and enable effective adaption to the burden of the pandemic.

Sexually dimorphic expression of a chicken sex chromosome gene (VCP) reflects differences in gonadal development between males and females.

The chicken has a Z-W sex chromosome system, in which the males are the homogametic sex (ZZ) and the females the heterogametic sex (ZW). The smaller W chromosome is generally considered to be a highly degraded copy of the Z chromosome that retains around 28-30 homologous protein-coding genes' These Z-W homologues are thought to have important, but undefined, roles in development, and here we explore the role of one of these genes, VCP (Valosin Containing Protein) in gonadogenesis. We established RNA expression levels of both Z and W VCP homologues, the levels of VCP protein, and the cellular localization of VCP protein in male and female embryonic gonads during development.

What Can We Learn From More Than 140,000 Moments of Ecological Momentary Assessment-Assessed Negative Emotion and Ambulatory Blood Pressure? A Systematic Review and Meta-Analysis.

Objective: Two decades of research has examined within-person associations between negative emotion states and ambulatory blood pressure (ABP) using ecological momentary assessment (EMA), but no meta-analysis has been conducted. We conducted this systematic review and meta-analysis to quantify the magnitude of this association and identify moderators, review strengths and weaknesses in conceptual and measurement approaches, and provide recommendations.

Methods: We searched databases (PsycINFO, PubMed), identified 15 studies, and obtained data from 13 studies (n = 2511; 142,307 observations).
