Right Ventricular Strain Is Common in Intubated COVID-19 Patients and Does Not Reflect Severity of Respiratory Illness.

Background: Right ventricular (RV) dysfunction is common and associated with worse outcomes in patients with coronavirus disease 2019 (COVID-19). In non-COVID-19 acute respiratory distress syndrome, RV dysfunction develops due to pulmonary hypoxic vasoconstriction, inflammation, and alveolar overdistension or atelectasis. Although similar pathogenic mechanisms may induce RV dysfunction in COVID-19, other COVID-19-specific pathology, such as pulmonary endothelialitis, thrombosis, or myocarditis, may also affect RV function.

Anthropogenic pressures increase extinction risk of an isolated Asian elephant (Elephas maximus) population in southwestern China, as revealed by a combination of molecular- and landscape-scale approaches.

Identification of the effect of anthropogenic threats on ecosystem is crucial. We used molecular tools and remote sensing to evaluate the population status of an isolated Asian elephant population in southwestern China in response to changes in habitat suitability between 1989 and 2019. A total of 22 unique genotypes were identified from 117 dung samples collected between March and June 2018 using microsatellite DNA analysis, including 13 males and 9 females.

Foraging trip duration of honeybee increases during a poor air quality episode and the increase persists thereafter.

Increased concentration of airborne particulate matter (PM) in the atmosphere alters the degree of polarization of skylight which is used by honeybees for navigation during their foraging trips. However, little has empirically shown whether poor air quality indeed affects foraging performance (foraging trip duration) of honeybee. Here, we show apparent increases in the average duration of honeybee foraging during and after a heavy air pollution event compared with that of the pre-event period.

Hierarchically Porous Ceramics via Direct Writing of Binary Colloidal Gel Foams.

Hierarchically porous ceramics with a high specific surface area and interconnected porosity may find potential application as particulate filters, catalyst supports, and battery electrodes. We report the design and programmable assembly of cellular ceramic architectures with controlled pore size, volume, and interconnectivity across multiple length scales via direct foam writing. Specifically, binary colloidal gel foams are created that contain entrained bubbles stabilized by the irreversible adsorption of attractive alumina and carbon (porogen) particles at their air-water interfaces.

Exploring the impact of cultural beliefs in the self-management of type 2 diabetes among Black sub-Saharan Africans in the UK - a qualitative study informed by the PEN-3 cultural model.

Objective: The purpose of this study was to examine cultural beliefs, attitudes, and practices of Black sub-Saharan Africans (BsSAs) in the UK regarding their type 2 diabetes (T2D) self-management using the concepts of the PEN-3 cultural model.

Method: A qualitative study involved 36 semi-structured interviews with BsSAs living with T2D in the UK to examine relevant cultural practices and beliefs that have contributed to the uneven burden of self-management behaviours. A narrative thematic analysis of the data was then conducted for the study using NVivo software and guided by the PEN-3 cultural model, which moves beyond individualistic health behaviour models of diabetes but centralises culture in understanding health behaviours.

Cognitive and Affective Risk Beliefs and their Association with Protective Health Behavior in Response to the Novel Health Threat of COVID-19.

The COVID-19 global pandemic is an unprecedented health threat for which behavior is critical to prevent spread and personal factors could contribute to decisions for protective action. The purpose of this study was to describe associations of COVID-19 related behaviors capturing a snapshot in time during the height of the first wave of the pandemic. We tested perceptions of likelihood and severity of infection, worry, and their associations with behavior.

Challenges in implementing emergency obstetric care (EmOC) policies: perspectives and behaviours of frontline health workers in Uganda.

Uganda is among the sub-Saharan African Countries which continue to experience high preventable maternal mortality due to obstetric emergencies. Several Emergency Obstetric Care (EmOC) policies rolled out have never achieved their intended targets to date. To explore why upstream policy expectations were not achieved at the frontline during the MDG period, we examined the implementation of EmOC policies in Uganda by; exploring the barriers frontline implementers of EmOC policies faced, their coping behaviours and the consequences for maternal health.

Retroperitoneal lymph node dissection for germ cell tumour.

Retroperitoneal lymph node dissection (RPLND) is an infrequently used, but important part of the management of men with metastatic germ cell tumours. The surgery aims to remove the lymph nodes from the primary retroperitoneal landing site from testicular tumours, usually accomplished by removing tissue surrounding the great vessels using a split-and-roll technique. RPLND may be carried out as a primary surgical procedure for staging or treatment of metastases.

Dual Inhibition of MEK and AXL Targets Tumor Cell Heterogeneity and Prevents Resistant Outgrowth Mediated by the Epithelial-to-Mesenchymal Transition in NSCLC.

The epithelial-to-mesenchymal transition (EMT) is a dynamic epigenetic reprogramming event that occurs in a subset of tumor cells and is an initiating step toward invasion and distant metastasis. The process is reversible and gives plasticity to cancer cells to survive under variable conditions, with the acquisition of cancer stem cell-like characteristics and features such as drug resistance. Therefore, understanding survival dependencies of cells along the phenotypic spectrum of EMT will provide better strategies to target the spatial and temporal heterogeneity of tumors and prevent their ability to bypass single-inhibitor treatment strategies.

Sodium-glucose cotransporter-2 (SGLT2) inhibitor-induced euglycemic diabetic ketoacidosis complicating the perioperative management of a patient with type 2 diabetes mellitus (T2DM) and Fournier's gangrene: A case report.

Introduction: Sodium glucose cotransporter-2 inhibitors (SGLT2) are an increasingly administered class of medication used to lower blood glucose levels in patients with type 2 diabetes mellitus. Diabetic ketoacidosis (DKA) and Fournier's gangrene are rare, but potentially catastrophic side effects of SGLT2 inhibitors. This manuscript reports a case of both DKA and Fournier's gangrene in the context of SGLT2 inhibitor use.

No Evidence of Food or Alcohol Substitution in Response to a Sweetened Beverage Tax.

Introduction: Evidence suggests real-world beverage taxes reduce sweetened beverage purchases, but it is unknown if consumers consequently increase food or alcohol purchases. This study examines whether Philadelphia's 1.5 cents/ounce beverage tax was associated with substitution to 3 kinds of hypothesized substitutes: snacks, nontaxed beverage concentrates, and alcohol.

Disseminated intravascular coagulopathy: a complication of Stevens-Johnson syndrome/toxic epidermal necrolysis.

Background: The purpose of this study was to retrospectively assess clinical characteristics and mortality rate of Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) in patients who developed disseminated intravascular coagulation (DIC).

Methods: A systematic retrospective chart review of all patients with concurrent clinical diagnosis of DIC and SJS/TEN between July 1, 2012, and January 1, 2020, at the Mayo Clinic was performed.

Results: The incidence of DIC in patients with SJS/TEN was 1.

Cytomegalovirus-Specific T Cell Epitope Recognition in Congenital Cytomegalovirus Mother-Infant Pairs.

Congenital cytomegalovirus (cCMV) infection is the most common infection acquired before birth and from which about 20% of infants develop permanent neurodevelopmental effects regardless of presence or absence of symptoms at birth. Viral escape from host immune control may be a mechanism of CMV transmission and infant disease severity. We sought to identify and compare CMV epitopes recognized by mother-infant pairs.

Ensuring competency in focused cardiac ultrasound: a systematic review of training programs.

Background: Focused cardiac ultrasound (FoCUS) is a valuable skill for rapid assessment of cardiac function and volume status. Despite recent widespread adoption among physicians, there is limited data on the optimal training methods for teaching FoCUS and metrics for determining competency. We conducted a systematic review to gain insight on the optimal training strategies, including type and duration, that would allow physicians to achieve basic competency in FoCUS.

Experience of migraine, its severity, and perceived efficacy of treatments among cannabis users.

Objectives: As the legal and cultural landscape surrounding cannabis use in the United States continues to evolve, more Americans are turning to cannabis to self-medicate a number of ailments, including migraines. The purpose of the present study was to examine patterns of cannabis use and its associated relief among migraineurs.

Design: Participants were N = 589 adult cannabis users living in states with full legal access.

A peer support intervention for first-time mothers: Feasibility and preliminary efficacy of the mummy buddy program.

Background: The transition to motherhood, although joyous, can be highly stressful, and the availability of professional postpartum support for mothers is often limited. Peer volunteer support programs may offer a viable and cost-effective method to provide community-based support for new mothers.

Aim: To determine the feasibility of a peer volunteer support program-The Mummy Buddy Program-in which experienced volunteer mothers are paired with, and trained to offer social support to, first-time mothers.

A One Health Approach to Strengthening Antimicrobial Stewardship in Wakiso District, Uganda.

Antimicrobial stewardship (AMS), as one of the global strategies to promote responsible use of antimicrobials to prevent antimicrobial resistance (AMR), remains poor in many low-and middle-income countries (LMICs). We implemented a project aimed at strengthening AMS in Wakiso district, Uganda using a One Health approach. A total of 86 health practitioners (HPs), including animal health workers, and 227 community health workers (CHWs) participated in training workshops, and over 300 pupils from primary schools were sensitized on AMR, AMS, and infection prevention and control (IPC).

'I know those people will be approachable and not mistreat us': a qualitative study of inspectors and private drug sellers' views on peer supervision in rural Uganda.

Background: Peer supervision improves health care delivery by health workers. However, in rural Uganda, self-supervision is what is prescribed for licensed private drug sellers by statutory guidelines. Evidence shows that self-supervision encourages inappropriate treatment of children less than 5 years of age by private drug sellers.

Post-Release Monitoring of Western Grey Kangaroos ( ) Relocated from an Urban Development Site.

The expansion of urban areas and associated clearing of habitat can have severe consequences for native wildlife. One option for managing wildlife in these situations is to relocate them. While there is a general perception that relocation is humane, transparency of outcomes is lacking.
