An image dataset for surveillance of personal protective equipment adherence in healthcare.

Proper personal protective equipment (PPE) use is critical to prevent disease transmission to healthcare providers, especially those treating patients with a high infection risk. To address the challenge of monitoring PPE usage in healthcare, computer vision has been evaluated for tracking adherence. Existing datasets for this purpose, however, lack a diversity of PPE and nonadherence classes, represent single not multiple providers, and do not depict dynamic provider movement during patient care.

Neutralizing antibody immune correlates in COVAIL trial recipients of an mRNA second COVID-19 vaccine boost.

Neutralizing antibody titer has been a surrogate endpoint for guiding COVID-19 vaccine approval and use, although the pandemic's evolution and the introduction of variant-adapted vaccine boosters raise questions as to this surrogate's contemporary performance. For 985 recipients of an mRNA second bivalent or monovalent booster containing various Spike inserts [Prototype (Ancestral), Beta, Delta, and/or Omicron BA.1 or BA.

Understanding the Etiology of Externalizing Problems in Young Children: The Roles of Callous-Unemotional Traits and Irritability.

Objective: Callous-unemotional traits (CU), characterized as a lack of guilt and empathy; and irritability, a tendency to show anger and frustration; are 2 risk factors for externalizing behavioral problems. Externalizing problems, CU and irritability are all heritable. However, there is a dearth of studies examining the genetic and environmental associations between the 3 domains.

Caregiver food allergy self-efficacy explains the relationship between perceived food allergy severity and burden.

Objective: Caregiver perceived food allergy severity is associated with food allergy burden, while caregiver food allergy self-efficacy has been linked to improved quality of life for caregivers. This study examined the mediating effect of caregiver food allergy self-efficacy on the relationship between perceived food allergy severity and caregiver food allergy burden.

Methods: Caregivers of children diagnosed with IgE-mediated food allergy were recruited from pediatric allergy clinics to complete demographic and medical questionnaires, the Food Allergy Independent Measure-Parent Form, the Food Allergy Self-Efficacy Scale for Parents, and the Food Allergy Quality of Life-Parental Burden.

Predictors of willingness to participate in COVID-19 clinical trials among Black and Latino adults.

Introduction: Black and Latino individuals are underrepresented in COVID-19 treatment and vaccine clinical trials, calling for an examination of factors that may predict willingness to participate in trials.

Methods: We administered the Common Survey 2.0 developed by the Community Engagement Alliance (CEAL) Against COVID-19 Disparities to 600 Black and Latino adults in Baltimore City, Prince George's County, Maryland, Montgomery County, Maryland, and Washington, DC, between October and December 2021.

Skeletal Maturity Might Not Be a Factor in Optimizing Outcomes in Total Hip Arthroplasty.

Introduction Total hip arthroplasty (THA) is rarely indicated in the skeletally immature population. In these instances, there is concern for implant survival compared to the traditional older population. There has been a steady rise in the use of THA in the pediatric population due to improvements in surgical techniques.

Association of Rate of Functional Recovery With Therapy Time and Content Among Adults With Acquired Brain Injuries in Inpatient Rehabilitation.

Objective: To examine associations among the time and content of rehabilitation treatment with self-care and mobility functional gain rate for adults with acquired brain injury.

Design: Retrospective cohort study using electronic health record and administrative billing data.

Setting: Inpatient rehabilitation unit at a large, academic medical center.

Pediatric Advance Care Planning and Adolescent Preparedness and Quality of Life: An RCT.

Background And Objective: To evaluate the efficacy of Family-Centered Advance Care Planning for Teens With Cancer (FACE-TC) on adolescents' quality of life.

Methods: A clinical trial randomized adolescent-family dyads at a 2:1 ratio to either FACE-TC or control. FACE-TC dyads received 3 weekly 60-minute sessions: Lyon Pediatric Advance Care Planning Survey; Next Steps: Respecting Choices; and Five Wishes.

Head and Neck Paraganglioma in Pacak-Zhuang Syndrome.

Head and neck paragangliomas (HNPGLs) are typically slow-growing, hormonally inactive tumors of parasympathetic paraganglia. Inactivation of prolyl-hydroxylase domain-containing 2 protein causing indirect gain-of-function of hypoxia-inducible factor-2α (HIF-2α), encoded by EPAS1, was recently shown to cause carotid body hyperplasia. We previously described a syndrome with multiple sympathetic paragangliomas caused by direct gain-of-function variants in EPAS1 (Pacak-Zhuang syndrome, PZS) and developed a corresponding mouse model.

Long-Term Revision-Free Survival Following Operative Fixation of Femoral Neck Fractures in Young Adults.

Objectives: To identify the rate of fixation failure following femoral neck fracture (FNF) fixation in young adults within a national database.

Methods: Design: Retrospective cohort study.

Setting: National all-payer claims database.

Utilization of Telemedicine for Patients Receiving In-center Hemodialysis in the United States.

Background: In March 2020, responding to the COVID-19 pandemic, federal emergency waivers in the United States enabled kidney care providers (nephrologists and advanced practice providers) to substitute face-to-face in-center hemodialysis visits with telemedicine encounters. We examined whether the frequency of kidney care provider visits and hospitalizations were associated with telemedicine use in hemodialysis care.

Methods: We used Medicare claims to identify US patients receiving in-center hemodialysis during the first 16 months of the COVID-19 pandemic.

Estimating the Proportion of Telehealth-Able United States Emergency Department Visits.

Study Objective: We use national emergency department (ED) data to identify the proportion of "telehealth-able" ED visits, defined as potentially conductible by Video Only or Video Plus (with limited outpatient testing).

Methods: We used ED visits by patients 4 years of age and older from the 2019 National Hospital Ambulatory Medical Care Survey and applied survey weighting for national representativeness. Two raters categorized patient-described Reasons for Visit (RFV) as telehealth-able (yes, no, uncertain) for both Video Only and Video Plus visits.

Sleep and breathing in children with Joubert syndrome and a review of other rare congenital hindbrain malformations.

Background: Joubert syndrome (JS) is an autosomal recessive disorder with a distinctive mid-hindbrain malformation known as the "molar tooth sign" which involves the breathing control center and its connections with other structures. Literature has reported significant respiratory abnormalities which included hyperpnea interspersed with apneic episodes during wakefulness. Larger-scale studies looking at polysomnographic findings or subjective reports of sleep problems in this population have not yet been published.

Planum Temporale Asymmetries in Primates: A Comparative Study in Great Apes and Monkeys.

Objectives: Most human brains exhibit left hemisphere asymmetry for planum temporale (PT) surface area and gray matter volume, which is interpreted as cerebral lateralization for language. Once considered a uniquely human feature, PT asymmetries have now been documented in chimpanzees and olive baboons. The goal of the current study was to further investigate the evolution of PT asymmetries in nonhuman primates.

Psychometric Evaluation of the Scleroderma Skin Questionnaire: A Novel Patient Reported Outcome for Skin Disease in Patients with Systemic Sclerosis.

Objective: To evaluate the psychometric properties of the Scleroderma Skin Questionnaire (SSQ), a novel patient-reported outcome (PRO) to assess systemic sclerosis (SSc) related skin symptoms.

Methods: The SSQ was administered to 799 adults (mean age 52.7; 82% female) enrolled in the SSc Collaborative National Quality and Efficacy Registry (CONQUER).

Effect of Characteristic Inflammatory and Structural Pelvic Magnetic Resonance Imaging Lesions on Expert Assessment of Axial Juvenile Spondyloarthritis.

Objective: To evaluate the influence of pelvic magnetic resonance imaging (MRI) findings on axial disease assessment in juvenile spondyloarthritis (JSpA).

Methods: This was a cross-sectional study of patients with JSpA with suspected axial disease. Three experts reviewed each case and rated their confidence (-3 to +3) in the presence of axial disease, first with clinical data and second with clinical and MRI data.

Infrainguinal bypass for limb salvage has comparable mortality and affords a better chance of home discharge than amputation among octogenarians.

Background: Infrainguinal bypass for chronic limb-threatening ischemia (CTLI) in octogenarians is considered a high-risk procedure due to the presumed associated frailty of the patient population. However, the alternative which is major amputation may not be a better option. This study retrospectively compares the outcomes of bypass versus major amputation for functionally independent and partially dependent patients.

The partisanship of mayors has no detectable effect on police spending, police employment, crime, or arrests.

In this paper, we examine whether mayors' partisan affiliations lead to differences in crime and policing. We use a large new dataset on mayoral elections and three different modern causal inference research designs (a regression discontinuity design centered around close elections and two robust difference-in-differences methods) to determine the causal effect of mayoral partisanship on crime, arrests, and racial differences in arrest patterns in medium and large US cities. We find no evidence that mayoral partisanship affects police employment or expenditures, police force or leadership demographics, overall crime rates, or numbers of arrests.

Quantification of Particle-Associated Viruses in Secondary Treated Wastewater Effluent.

Viruses can interact with a broad range of inorganic and organic particles in water and wastewater. These associations can protect viruses from inactivation by quenching chemical disinfectants or blocking ultraviolet light transmission, and a much higher dosage of disinfectants is required to inactivate particle-associated viruses than free viruses. There have been only few studies of the association of viruses with particles in wastewater, particularly in secondary treated effluent.

Trends in screening and treatment of osteoporosis after periprosthetic fractures from 2010 to 2020.

Unlabelled: Osteoporosis is often underrecognized and undertreated following periprosthetic fractures (PPF). Our study found that between 2010 and 2020, there has been no significant change in the rates of osteoporosis screening or treatment within 1 year following PPF. Orthopedic surgeons can play an integral role in helping to curtail the osteoporosis epidemic.

Transcriptomic and functional characterization of megakaryocytic-derived platelet-like particles: impaired aggregation and prominent anti-tumor effects.

Platelet-like particles (PLPs), derived from megakaryocytic cell lines MEG-01 and K-562, are widely used as a surrogate to study platelet formation and function. We demonstrate by RNA-Seq that PLPs are transcriptionally distinct from platelets. Expression of key genes in signaling pathways promoting platelet activation/aggregation, such as the PI3K/AKT, protein kinase A, phospholipase C, and α-adrenergic and GP6 receptor pathways, was missing or under-expressed in PLPs.
