Objective: To identify the medical schools producing the most PM&R residents from 2017 to 2021 and potential influencing factors toward this production.

Mosquito floral visitation and pollination.

We often consider mosquitoes through an 'anthropocentric lens' that disregards their interactions with nonhuman and nonpathogenic organisms, even though these interactions can be harnessed for mosquito control. Mosquitoes have been recognized as floral visitors, and pollinators, for more than a century. However, we know relatively little about mosquito-plant interactions, excepting some nutrition and chemical ecology-related topics, compared with mosquito-host interactions, and frequently use flawed methodology when investigating them.

An update and review of arthropod vector sensory systems: Potential targets for behavioural manipulation by parasites and other disease agents.

For over a century, vector ecology has been a mainstay of vector-borne disease control. Much of this research has focused on the sensory ecology of blood-feeding arthropods (black flies, mosquitoes, ticks, etc.) with terrestrial vertebrate hosts.

Methods: Medical records were retrospectively reviewed to obtain information regarding clinical characteristics, treatments, and outcomes.

An integrated approach to address diabetes in the context of food insecurity: Delivering health study protocol.

Background: Diabetes self-management education and support (DSMES) interventions among food insecure individuals with type 2 diabetes (T2D) have found modest improvements in nutrition and health outcomes but are limited by barriers to attendance and retention. This study applies a community-based participatory research approach, engaging community members at all levels of intervention planning, development, implementation, and dissemination, to deliver a plain-language DSMES curriculum to food insecure community members with T2D.

Methods: This is a single-arm, pre-post design assessing the efficacy of a 12-week home-delivered DSMES curriculum and T2D-appropriate food box intervention to improve the nutrition and health outcomes of food insecure individuals with T2D.

Modular Synthesis and Patterning of High-Stiffness Networks by Postpolymerization Functionalization with Iron-Catechol Complexes.

Bioinspired iron-catechol cross-links have shown remarkable success in increasing the mechanical properties of polymer networks, in part due to clustering of Fe-catechol domains which act as secondary network reinforcing sites. We report a versatile synthetic procedure to prepare modular PEG-acrylate networks with independently tunable covalent bis(acrylate) and supramolecular Fe-catechol cross-linking. Initial control of network structure is achieved through radical polymerization and cross-linking, followed by postpolymerization incorporation of catechol units via quantitative active ester chemistry and subsequent complexation with iron salts.

On the impact of advanced driver assistance systems on driving distraction and risky behaviour: An empirical analysis of irish commercial drivers.

Advanced driver assistance systems (ADAS) present promising benefits in mitigating road collisions. However, these benefits are limited when risky drivers continue engaging in distraction events. While there is evidence that real-time warnings help improve driving behaviour, the sustained benefits of warning-based ADAS on reducing driving distraction in light commercial vehicle (LCV) drivers remain unclear.

Single-Leg Squat and Reported Pain in Collegiate Softball Pitchers.

Background: Single-leg squat (SLS) performance is related to altered mechanics related to injury during the windmill softball pitch; however, it is unknown if SLS kinematics differ between softball pitchers with and without upper extremity pain.

Purpose/hypothesis: The purpose of this study was to compare knee valgus, trunk rotation, trunk lateral flexion, and trunk flexion during an SLS in collegiate softball pitchers with and without self-reported upper extremity pain. It was hypothesized that those who reported upper extremity pain would show increased compensatory trunk and knee kinematics compared with those without pain.

Impact on social capital and learning engagement due to social media usage among the international students in the U.S.

International students who pursue their academic goals in United States are prone to difficulties when attempting to build social resources and adjust to the new culture. Social media is a practical means of connection due to its ease of use and accessibility. Previous research has indicated contradictory effects of social media use on academic engagement.

The framework species method: harnessing natural regeneration to restore tropical forest ecosystems.

As interest in restoring tropical forests surges, so does the need for effective methods to ensure success. The framework species method (FSM) restores forest ecosystems by densely planting open sites, close to natural forest, with woody species, indigenous to the reference ecosystem and selected for their ability to accelerate ecological succession. Criteria for selecting framework species include: (i) representative of the reference forest ecosystem, (ii) tolerant of open conditions, (iii) ability to suppress weeds, (iv) attractiveness to seed-dispersing animals and (v) easily propagated.

Associations between mobility patterns and COVID-19 deaths during the pandemic: A network structure and rank propagation modelling approach.

Background: From February 2020, both urban and rural Ireland witnessed the rapid proliferation of the COVID-19 disease throughout its counties. During this period, the national COVID-19 responses included stay-at-home directives issued by the state, subject to varying levels of enforcement.

Methods: In this paper, we present a new method to assess and rank the causes of Ireland COVID-19 deaths as it relates to mobility activities within each county provided by Google while taking into consideration the epidemiological confirmed positive cases reported per county.

Carbapenemase production among less-common Enterobacterales genera: 10 US sites, 2018.

Background: Historically, United States' carbapenem-resistant Enterobacterales (CRE) surveillance and mechanism testing focused on three genera: , , and (EsKE); however, other genera can harbour mobile carbapenemases associated with CRE spread.

Objectives: From January through May 2018, we conducted a 10 state evaluation to assess the contribution of less common genera (LCG) to carbapenemase-producing (CP) CRE.

Methods: State public health laboratories (SPHLs) requested participating clinical laboratories submit all Enterobacterales from all specimen sources during the surveillance period that were resistant to any carbapenem (Morganellaceae required resistance to doripenem, ertapenem, or meropenem) or were CP based on phenotypic or genotypic testing at the clinical laboratory.

Trends in alcohol intoxication among native and immigrant youth in Sweden, 1999-2017: A comparison across family structure and parental employment status.

Background: Developing a better understanding of drinking patterns across immigrant generations and how these change over time is important for the development of effective alcohol polices. This study investigates the direction and rate of change in youth alcohol intoxication over time, based on immigrant status, and by family structure and parental employment status.

Method: The study is based on eight nationally representative school surveys conducted by the Swedish National Council for Crime Prevention between 1999 and 2017, with a combined sample of 50,657 adolescents.

Single-Leg Squat Compensations Are Associated With Softball Pitching Pathomechanics in Adolescent Softball Pitchers.

Background: A lack of lumbopelvic-hip complex (LPHC) stability is often associated with altered pitching mechanics, thus increasing pain and injury susceptibility. The single-leg squat (SLS) is a simple diagnostic tool used to examine LPHC stability.

Purpose: To examine the relationship between trunk compensatory kinematics during the SLS and kinematics at foot contact during the windmill pitch.

Extending the Heston model to forecast motor vehicle collision rates.

We present an alternative approach to the forecasting of motor vehicle collision rates. We adopt an oft-used tool in mathematical finance, the Heston Stochastic Volatility model, to forecast the short-term and long-term evolution of motor vehicle collision rates. We incorporate a number of extensions to the Heston model to make it fit for modelling motor vehicle collision rates.

Nursing and paramedicine student and academic perceptions of the two phase debrief model: A thematic analysis.

Simulation debriefing standards and models recommend simulation facilitators spend time debriefing learner feelings and clinical reasoning following the simulation scenario. Many debriefing models are available, more so in nursing than in paramedicine, however few models combine specific frameworks to debrief learner feelings and unpack cognitive decisions. The Two Phase Debrief model was designed to support debriefers to spend equal amounts of time debriefing learner felt reactions and clinical decision making, guided by specific tools and skills for each phase.

Immune or at-risk? Stock markets and the significance of the COVID-19 pandemic.

The closure of borders and traditional commerce due to the COVID-19 pandemic is expected to have a lasting financial impact. We determine whether the growth in COVID-19 affected index prices by examining equity markets in five regional epicentres, along with a 'global' index. We also investigate the impact of COVID-19 after controlling for investor sentiment, credit risk, liquidity risk, safe-haven asset demand and the price of oil.

Kinematic Differences Exist Between the Fastball, Changeup, Curveball, and Dropball Pitch Types in Collegiate Softball Pitchers.

Background: A majority of softball literature focuses on the mechanics associated with pain and injury within a single pitch type per study; however, the generalizability of these findings is unknown since a kinematic comparison has yet to be performed between pitch types. Understanding kinematic differences between pitch types can be used to identify risk factors for injury, improve safety guidelines, and improve performance by linking specific mechanics with desired pitch outcomes.

Hypothesis/purpose: The purpose of this study was to compare kinematics between the fastball, changeup, curveball, and dropball pitch types in collegiate softball pitchers.
