Objectives: The COVID-19 pandemic has had an impact on emergency medical services (EMS) and its guidelines, which aid in patient care. This study characterizes state and territory EMS office recommendations to EMS statewide operational and clinical guidelines and describes the mechanisms of distribution and implementation during the COVID-19 pandemic.

Methods: A mixed-methods study was conducted in 2 phases.

miR-3132 upregulates surface TRAIL to induce apoptotic cell death in cancer cells.

TRAIL-based therapies are of significant clinical interest because of its unique ability to induce apoptosis in cancer cells while sparing normal and untransformed cells. This selective antitumor potential of the TRAIL pathway has been harnessed by development of therapeutics including recombinant (rh)TRAIL and TRAIL-receptor agonist antibodies such as mapatumumab and lexatumumab. While these TRAIL-based therapies have proven successful in preclinical studies and safe in early phase clinical trials, the limited serum half-life has been a hurdle for further clinical development.

Development of a standards-based phenotype model for gross motor function to support learning health systems in pediatric rehabilitation.

Introduction: Research and continuous quality improvement in pediatric rehabilitation settings require standardized data and a systematic approach to use these data.

Methods: We systematically examined pediatric data concepts from a pediatric learning network to determine capacity for capturing gross motor function (GMF) for children with Cerebral Palsy (CP) as a demonstration for enabling infrastructure for research and quality improvement activities of an LHS. We used an iterative approach to construct phenotype models of GMF from standardized data element concepts based on case definitions from the Gross Motor Function Classification System (GMFCS).

Geographic mobility in the emergency medicine residency match and the influence of gender.

Objectives: Women are underrepresented in emergency medicine (EM) leadership. Some evidence suggests that geographic mobility improves career advancement. We compared movement between medical school and residency by gender.

Rapid Adoption of Telemedicine in Rheumatology Care During the COVID-19 Pandemic Highlights Training and Supervision Concerns Among Rheumatology Trainees.

Objective: To evaluate the impact of telemedicine use during the coronavirus disease 2019 (COVID-19) pandemic on rheumatology trainees.

Methods: A voluntary, anonymous, web-based survey was administered in English, Spanish, or French from August 19 to October 5, 2020. Adult and pediatric rheumatology trainees were invited to participate via social media and email.

Risk stratification with video capsule endoscopy leads to fewer hospital admissions in emergency department patients with low-risk to moderate-risk upper gastrointestinal bleed: A multicenter clinical trial.

Objective: In US emergency departments (EDs), the physician has limited ability to evaluate for common and serious conditions of the gastrointestinal (GI) mucosa such as a bleeding peptic ulcer. Although many bleeding lesions are self-limited, the majority of these patients require emergency hospitalization for upper endoscopy (EGD). We conducted a clinical trial to determine if ED risk stratification with video capsule endoscopy (VCE) reduces hospitalization rates for low-risk to moderate-risk patients with suspected upper GI bleeding.

A randomized controlled trial of an innovative, user-friendly, interactive smartphone app-based lifestyle intervention for weight loss.

Objectives: Most electronically delivered lifestyle interventions are labor intensive, requiring logging onto websites and manually recording activity and diet. Cumbersome technology and lack of a human coach may have contributed to the limitations of prior interventions. In response, the current program of research created a comprehensive electronically delivered lifestyle intervention using a user-friendly, interactive, smartphone app-based model, and evaluated it in a randomized controlled trial.

Antifungal Effect of Piezoelectric Charges on PMMA Dentures.

Candida-associated denture stomatitis is a recurring disease affecting up to 67% of denture wearers. Poly(methyl methacrylate) (PMMA) remains the main material employed in the fabrication of dentures due to its desirable physical, mechanical, and aesthetic properties. However, the improvement of its antimicrobial properties remains a challenge.

Development of a standardized histopathology scoring system using machine learning algorithms for intervertebral disc degeneration in the mouse model-An ORS spine section initiative.

Mice have been increasingly used as preclinical model to elucidate mechanisms and test therapeutics for treating intervertebral disc degeneration (IDD). Several intervertebral disc (IVD) histological scoring systems have been proposed, but none exists that reliably quantitate mouse disc pathologies. Here, we report a new robust quantitative mouse IVD histopathological scoring system developed by building consensus from the spine community analyses of previous scoring systems and features noted on different mouse models of IDD.

Venous thromboembolism detected by FDG-PET/CT in cancer patients: a common, yet life-threatening observation.

Cancer patients are at markedly increased risk for venous thromboembolism (VTE). Early detection of VTE may decrease morbidity and mortality in this population. We conducted this study to evaluate the ability of FDG-PET/CT to detect thrombosis in cancer patients.

Serum-Derived Small Extracellular Vesicles From Diabetic Mice Impair Angiogenic Property of Microvascular Endothelial Cells: Role of EZH2.

Background Impaired angiogenic abilities of the microvascular endothelial cell (MVEC) play a crucial role in diabetes mellitus-impaired ischemic tissue repair. However, the underlying mechanisms of diabetes mellitus-impaired MVEC function remain unclear. We studied the role of serum-derived small extracellular vesicles (ssEVs) in diabetes mellitus-impaired MVEC function.

Association of Plasmodium falciparum kelch13 R561H genotypes with delayed parasite clearance in Rwanda: an open-label, single-arm, multicentre, therapeutic efficacy study.

Background: Partial artemisinin resistance is suspected if delayed parasite clearance (ie, persistence of parasitaemia on day 3 after treatment initiation) is observed. Validated markers of artemisinin partial resistance in southeast Asia, Plasmodium falciparum kelch13 (Pfkelch13) R561H and P574L, have been reported in Rwanda but no association with parasite clearance has been observed. We aimed to establish the efficacy of artemether-lumefantrine and genetic characterisation of Pfkelch13 alleles and their association with treatment outcomes.
