Objective: To estimate changes in Boston Emergency Services Team (BEST) psychiatric emergency services (PES) encounter volume (total and by care team) and inpatient disposition during the first 8 months of the COVID-19 pandemic.

Methods: Data on 30,657 PES encounters was extracted from the four-county, BEST reporting system. The study period consisted of the first 34 weeks of 2019 and 2020.

A comparative analysis of anti-vax discourse on twitter before and after COVID-19 onset.

This study aimed to identify and assess the prevalence of vaccine-hesitancy-related topics on Twitter in the periods before and after the Coronavirus Disease 2019 (COVID-19) outbreak. Using a search query, 272,780 tweets associated with anti-vaccine topics and posted between 1 January 2011, and 15 January 2021, were collected. The tweets were classified into a list of 11 topics and analyzed for trends during the periods before and after the onset of COVID-19.

MISL: Multiple imputation by super learning.

Multiple imputation techniques are commonly used when data are missing, however, there are many options one can consider. Multivariate imputation by chained equations is a popular method for generating imputations but relies on specifying models when imputing missing values. In this work, we introduce multiple imputation by super learning, an update to the multivariate imputation by chained equations method to generate imputations with ensemble learning.

Muscle-Building Exercise and Weapon Carrying and Physical Fighting Among U.S. Adolescent Boys.

This study aimed to determine the association between engagement in muscle-building exercise and weapon carrying and physical fighting among adolescent boys. Cross-sectional data from the 2019 Youth Risk Behavior Survey (U.S.

Evaluating Different Strategies on the Blood Collection Counter Settings to Improve Patient Waiting Time in Outpatient Units.

Long patient waiting time is one of the major problems in the healthcare system and it would decrease patient satisfaction. Previous studies usually investigated how to improve the treatment flow in order to reduce patient waiting time or length of stay. The studies on blood collection counters have received less attention.

Victimization of Sexual Minority Latinx Youth: Results From a National Survey.

Limited previous research has explored the intersectional stress and trauma sexual minority (SM) Latinx youth experience generated by being part of at least two minoritized groups. The Dating Violence among Latino Adolescents (DAVILA) study employed a national sample of Latinx youth and queried a range of victimizations in the past year, via a bilingual phone survey. Of the 1525 12-18-year-old youth interviewed for DAVILA, 123 either identified as lesbian, gay, or bisexual or had at least one same-sex dating partner.

Bias Crime and Victimization Among Latinx Adults: Formal and Informal Help Seeking.

Latinx adults have become increasingly vulnerable to bias motivated victimization. The impact of such incidents on Latinx communities is severely understudied, particularly concerning whether or not victims will seek help as a result of such events. Evidence within other victimization contexts demonstrate Latinx populations may be less likely to seek formal help from police, medical providers, and other formal authorities, relying instead on informal support networks such as family and friends.

The Relationship of DNA Evidence to Prosecution Outcomes in Sexual Assault Cases.

This study examined the relationship between DNA evidence and outcomes of prosecution of sexual assault. Researchers coded data from prosecutor and crime laboratory files for sexual assault cases referred to prosecutors between 2005 and 2011 in a metropolitan jurisdiction in the northeastern United States. Cases with a DNA match were significantly more likely to move forward and result in conviction, even with other predictor variables statistically controlled.

"Making a Way Out of No Way:" Understanding the Sexual and Reproductive Health Care Experiences of Transmasculine Young Adults of Color in the United States.

Research focusing on the specific and unique sexual and reproductive health care experiences of transmasculine young adults of color are extremely scarce. We conducted five focus group discussions with 19 Black, Latinx, Asian, Native, and other transmasculine individuals of color aged 18-25 years in the greater Boston area. Using thematic analysis, we found that transmasculine young adults of color experienced cissexism, heterosexism, and racism in accessing and utilizing sexual and reproductive health services.

Combining cox regressions across a heterogeneous distributed research network facing small and zero counts.

Studies of the effects of medical interventions increasingly take place in distributed research settings using data from multiple clinical data sources including electronic health records and administrative claims. In such settings, privacy concerns typically prohibit sharing of individual patient data, and instead, cross-network analyses can only utilize summary statistics from the individual databases such as hazard ratios and standard errors. In the specific but very common context of the Cox proportional hazards model, we show that combining such per site summary statistics into a single network-wide estimate using standard meta-analysis methods leads to substantial bias when outcome counts are small.

School Nurses' Reports on Reopening Roles, Practices, and Concerns During the COVID-19 Pandemic at the Start of the 2020-2021 School Year.

The COVID-19 pandemic has caused major disruptions to U.S. school systems since March 2020.

Nonlinear behavior of disk spring with complex contact state.

Disk springs are widely used as preload and isolation due to their unique mechanical properties. In the prior research, the effect of linear friction on the disk spring was considered, but contact stiffness, another nonlinear contact factor, is ignored. Accordingly, in this paper, the asymmetric displacements of the contact edges are first derived, and the accurate friction dissipations are obtained, as a way to evaluate the effect of friction on the system.

Do We See Masculine Faces as Competent and Feminine Faces as Warm? Effects of Sexual Dimorphism on Facial Perception.

Previous research on non-facial features demonstrated that masculinity and femininity correlated highly with perceived competence and warmth, respectively. Several studies focused on dimorphic facial cues and found an association between masculine faces and competence. However, there's no study exploring the association between facial dimorphism and social judgment both using explicit and implicit experimental paradigms, i.

Endovascular Treatment of Giant Celiac Artery Aneurysm in Behcet's Disease.

We report a case of a 17-year-old male with Behcet's disease (BD) with giant celiac artery aneurysm and impending rupture. Over the past 8 weeks, patient began having intermittent back and abdominal pain that worsened and became persistent over the past few days. This was accompanied by anorexia and non-bilious vomiting.

Organizational commitment among physicians: A systematic literature review.

Purpose: Physicians work increasingly in larger organizations across different health care delivery systems. This systematic review examines the published empirical literature on organizational commitment among physicians within an international context.

Design: A systematic, PRISMA-guided review examining studies of organizational commitment among physicians published over time.

Cognitive Function in Liver Transplant Recipients Who Survived More Than 6 Months.

Introduction: Current research in the areas of liver transplant and cognitive function has primarily examined cognitive changes from pre- to 1-year posttransplant, resulting in an insufficient understanding of cognitive trajectory beyond early periods of transplant and its impact on self-management. This study aimed (1) to describe global and domain-specific cognitive function in liver transplant recipients who survived more than 6 months after transplant and (2) to describe patient and clinical characteristics of recipients with impaired global and/or domain-specific cognitive function. Further, this study explored the potential relationships between cognitive function and self-management by examining differences in cognitive function by levels of self-management.
