This study examines the phenotypic differences between wild-derived F2 Central Valley mosquitoes and the insecticide-susceptible Rockefeller (Rock) lab strain of Ae. aegypti. Given the rarity of wild pyrethroid-susceptible populations, the focus of this work is to develop an understanding of the resistance physiology in this invasive mosquito population and explore the potential of metabolites as diagnostic biomarkers for metabolic resistance. This study utilizes metabolomic, gene expression, and lifespan data for a comparison between strains. The findings indicate that wild-derived mosquitoes with greater metabolic resistance have a lifespan sensitivity to restricted larval nutrition. In terms of metabolism and gene expression, Central Valley mosquitoes show increased activity in oxidoreductase, glutathione metabolism, and the pentose phosphate pathway. Conversely, Rock mosquitoes display signs of metabolic inefficiency and mitochondrial dysregulation, likely tolerated due to the consistency and nutritional abundance of a controlled lab environment. The study also examines Ae. aegypti P450 and GSTE profiles in relation to other insecticide-resistant groups. While metabolomic data can differentiate our study groups, the challenges in biomarker development arise from few detected markers meeting high fold change thresholds.

BackgroundAdverse childhood experiences are prevalent robust risk factors for the development of substance use problems. However, less is known about the causal mechanisms that explain these relationships. While directly preventing adverse childhood experiences is ideal, it is not always possible. In such cases, the mechanisms themselves may be amenable to intervention, allowing for the effective prevention of problematic substance use among children exposed to adversity. Identifying such mechanisms is therefore a critical step for efforts aiming to reduce the high individual and societal burdens associated with substance use globally. ObjectiveThis study aims to systematically identify and synthesize evidence on the modifiable mediators and moderators of the relationship between adverse childhood experiences and substance use outcomes in young people (age 10-24 years). MethodsA systematic review will be conducted using PubMed, MEDLINE, PsycINFO, Web of Science, and CINAHL databases to determine the modifiable mediators and moderators of the relationship between adverse childhood experiences and substance use in young people. Data from the review will be qualitatively synthesized, unless we identify a sufficient number of studies (at least five) that examine the same type of adversity (eg, physical or sexual abuse) and the same mediator/moderator, in which case a quantitative synthesis (meta-analysis) will be conducted. If a quantitative synthesis is warranted, standardized effect estimates of the indirect (mediated) effect between adverse childhood experiences and substance use outcomes will be combined using a random-effects meta-analysis. Mediators/moderators will be grouped according to a socioecological perspective, using the four levels of individual, interpersonal, community, and public policy/culture. ResultsElectronic searches were completed in August 2019. A total of 4004 studies were included for screening after removing duplicates. After evaluating titles and abstracts against eligibility criteria, a further 3590 studies were excluded, leaving 415 studies for full-text screening. The results of the review are expected to be available by December 2020. ConclusionsThe mechanisms linking adverse childhood experiences and substance use outcomes in young people are vital targets for substance use prevention efforts. This review will provide evidence to inform the development of prevention strategies in order to interrupt the negative life trajectory that can begin with childhood adversity.

BACKGROUND AND OBJECTIVES: Multiple sclerosis (MS) commonly affects women in their childbearing years, necessitating discussion between patients and their MS treatment team around the issues of family planning, pregnancy, and postpartum experiences. This study assessed the impact of a diagnosis of MS on womens reproductive decision-making and on their perception of counseling received surrounding pregnancy. It also sought to evaluate trends in pregnancy and postpartum experiences and determine whether experiences differed by race, ethnicity, and zip code. METHODS: Women with an MS diagnosis seen at the University of Virginia MS Clinic or at Virginia Commonwealth University (VCU) MS Clinic were invited to participate in a survey study. MS disease and pregnancy history, and, when appropriate, reasons for pregnancy avoidance were collected. Respondents who had >1 pregnancy following MS diagnosis were asked to evaluate the counseling they received from medical professionals and to share their pregnancy experiences including complications during pregnancy, delivery outcomes, and postpartum experience including breastfeeding. RESULTS: Of the 280 respondents, 76.6% were currently receiving MS specialty care. Most of them (79.3%) had not been pregnant following MS diagnosis. Of them, 20.1% indicated that this decision was driven by MS-related concerns: MS worsening with pregnancy (47%); ability to care for child secondary to MS (35%); passing MS onto child (19%); stopping disease-modifying therapies to attempt pregnancy (14%); lack of knowledge about options for pregnancy and MS (9%). Women with a more recent estimated decade of pregnancy were more likely to report neurologist counseling regarding MS and pregnancy (pregnancy before 2000: 40%, 2000-2010: 64.7%, 2010- present: 83.3%; χ2 0.020). Breastfeeding initiation was reported in 71.4% of postdiagnosis pregnancies (median duration 6 months, interquartile range 1.75-11). DISCUSSION: Over the past few decades, women with MS have received a wide range of evolving guidance surrounding family planning, pregnancy, and postpartum care. Survey data suggest improvements in MS/pregnancy counseling and medical management in recent years, which may be driven by an increase in research in the field. There remains an important need and opportunity to improve counseling of women with MS who are considering pregnancy.

INTRODUCTION: Subjective improvement in gastrointestinal (GI) symptoms was assessed among patients using medical marijuana (MMJ). METHODS: Participants completed surveys at 0 days, 30 days, 6 months, and 12 months with questions about the severity of their GI symptoms on a scale from 1 (mild) to 3 (severe). RESULTS: In each survey, participants reported a significant decrease in GI symptom severity when using MMJ versus when not using MMJ (p < 0.05). The most common self-reported side effects from using MMJ were increased appetite (12-21.4%), fatigue (6-16.7%), anxiety (4-11.9%), cough (4-11.9%), headache (6-7.9%), and dry mouth (4-7.1%). CONCLUSION: In patients with chronic GI symptoms, MMJ may provide persistent symptom severity improvement. Limited product availability and mild to moderate side effects are factors to consider before trialing MMJ.

Formal private land conservation programs can be essential for achieving conservation goals, especially in ecosystems with substantial private ownership. Most deciduous oak woodlands in Humboldt County, California, and throughout the Pacific Northwest are located on private lands. The loss of these woodlands to conifer encroachment is a critical conservation concern, with implications for wildlife habitat, range management, cultural resources, biodiversity, and fire management. Private land programs depend on both incentives and voluntary cooperation. Through interviews and participant observation, we explored how and why landowners participate in oak woodland restoration. We are particularly interested in the role of social capital, which consists of trust and expectations of reciprocity. We found that oak woodland restoration depends on building social capital in order to leverage different skill sets and gain access to resources and technical expertise. Rather than a side effect of successful private land conservation, we assert that social capital is a necessary part of it, and that building and maintaining social capital can itself constitute a conservation goal.

BACKGROUND: Substance use increasingly contributes to early morbidity and mortality, which necessitates greater preparation of the healthcare workforce to mitigate its harm. The purpose of this systematic scoping review is to: 1) review published curricula on harm reduction for substance use implemented by undergraduate (UME) and graduate medical education (GME) in the United States and Canada, 2) develop a framework to describe a comprehensive approach to harm reduction medical education, and 3) propose additional content topics for future consideration. METHODS: PubMed, Scopus, ERIC: Education Resources Information Center (Ovid), and MedEdPORTAL were searched. Studies included any English language curricula about harm reduction within UME or GME in the United States or Canada from 1993 until Nov 22, 2021. Two authors independently reviewed and screened records for data extraction. Data were analyzed on trainee population, curricula objectives, format, content, and evaluation. RESULTS: Twenty-three articles describing 19 distinct educational programs across the United States were included in the final sample, most of which created their own curricula (n = 17). Data on educational content were categorized by content and approach. Most programs (85%) focused on introductory substance use knowledge and skills without an understanding of harm reduction principles. Based on our synthesis of the educational content in these curricula, we iteratively developed a Harm Reduction Educational Spectrum (HRES) framework to describe curricula and identified 17 discrete content topics grouped into 6 themes based on their reliance on harm reduction principles. CONCLUSIONS: Harm reduction is under-represented in published medical curricula. Because the drug supply market changes rapidly, the content of medical curricula may be quickly outmoded thus curricula that include foundational knowledge of harm reduction principles may be more enduring. Students should be grounded in harm reduction principles to develop the advanced skills necessary to reduce the physical harm associated with drugs while still simultaneously recognizing the possibility of patients ongoing substance use. We present the Harm Reduction Educational Spectrum as a new framework to guide future healthcare workforce development and to ultimately provide the highest-quality care for patients who use drugs.

Background: There is a lack of research on psychotherapy interventions for transition-aged students ages 18 to 21 that integrate horses or other equines in the provision of services. A critical early task in researching such complex interventions involves elucidating an intervention's critical elements and theoretical assumptions. Purpose: The purpose of this study was to develop a theory-driven logic model of a psychotherapy program for transition-aged students ages 18 to 21 that incorporated horses. Methodology/Approach: The research approach was qualitative description, a low-inference form of qualitative research. Data were collected via interviews with program stakeholders and through review of program documents, and were analyzed using a directed content analysis. Findings/Conclusions: The resulting logic model elucidates theoretical assumptions, activities, resources, outputs, outcomes, and theorized community impact of the psychotherapy program integrating horses. Implications: This study addresses several gaps in existing research on equine-assisted services, particularly the need to thoroughly describe an intervention and its theoretical assumptions, which can guide future program refinement and replication, and future research.

Established populations of Aedes aegypti, a mosquito vector of multiple major arthropod-borne viruses, were first found in three California (CA) cities in 2013. From 2013 to April 2021, Ae. aegypti thwarted almost all control efforts to stop its spread and expanded its range to 308 cities, including Exeter, in 22 counties in CA. Population genomic analyses have suggested that multiple genetically distinct Ae. aegypti populations were introduced into CA. However Ae. aegypti collected for the first time in 2014 in Exeter, appeared to be different from three major genetic clusters found elsewhere in CA. Due to intense control efforts by the Delta Vector Control District (DVCD), Ae. aegypti was thought to have been eliminated from Exeter in 2015. Unfortunately, it was recollected in 2018. It was not clear if the reemergence of Ae. aegypti in Exeter was derived from the bottlenecked remnants of the original 2014 Exeter population or from an independent invasion from a different population derived from surrounding areas. The goal of this work was to determine which of these scenarios occurred (recovery after bottleneck or reintroduction after elimination) and if elimination and reintroduction occurred to identify the origin of the invading population using a population genomic approach. Our results support the reintroduction after elimination hypothesis. The source of reintroduction, however, was unexpectedly from the southern CA cluster rather than from other two geographically closer central CA genetic clusters. We also conducted a knockdown resistance mutation profile, which showed Exeter 2014 had the lowest level of resistant alleles compared to the other populations, could have contributed towards DVCD’s ability to locally eliminate Ae. aegypti in 2014.

BACKGROUND AND OBJECTIVES: The COVID-19 pandemic highlighted the shortcomings of our health care delivery system for vulnerable populations and created a need to rethink health disparity education in medical training. We examined how the early COVID-19 pandemic impacted third-year medical students attitudes, perceptions, and sense of responsibility regarding health care delivery for vulnerable populations. METHODS: Third-year family medicine clerkship students at a large, private medical school in Philadelphia, Pennsylvania responded to a reflection assignment prompt asking how the COVID-19 pandemic impacted their thoughts about health care delivery for vulnerable populations in mid-2020 (N=59). Using conventional content analysis, we identified three main themes across 24 codes. RESULTS: Students recognized homeless individuals and Black, indigenous, and persons of color (BIPOC) as vulnerable populations impacted by the pandemic. Students reported causes of vulnerability that focused heavily on social determinants of health, increased risk for contracting COVID-19 infections, and difficulty adhering to COVID-19 prevention guidelines. Notable action-oriented approaches to addressing these disparities included health care reform and community health intervention. CONCLUSIONS: Our findings describe an educational approach to care for vulnerable populations based on awareness, attitudes, and social action. Medical education must continue to teach students how to identify ways to mitigate disparities in order to achieve health equity.

BackgroundCannabis use is increasing among adults to treat a variety of health conditions. Given the potential for interactions and adverse events, it is important to assess the use of medical cannabis along with other concomitant medications when assessing for polypharmacy.MethodsThe objective of this observational, longitudinal study was to examine medical cannabis (MC) use along with concomitant medications over 12 months in patients with serious medical conditions enrolled in the Pennsylvania (PA) Department of Health's (DOH) Medical Marijuana Program and to collect and catalog which forms of MC patients are taking along with their concomitant medications.ResultsThere were 213 participants who completed the baseline surveys in full, and 201, 187, and 175 who completed the 1, 6, and 12-month follow-up surveys. The mean age of the participants was 41.3 years, and 54.5% were female. The mean number of MC products taken at baseline was 3.41 and 3.47 at the 12-month survey. Participants took an average of 3.76 (SD 3.15) medications at baseline and 3.65 (SD 3.4) at 12 months. Most commonly used concomitant medications at baseline included vitamins (42.3%), antidepressants (29.1%), analgesics (22.1%), herbal products (19.7%), and anxiolytics (17.8%).ConclusionParticipants used multiple medical cannabis products to treat a number of medication conditions in conjunction with multiple medications.

BackgroundMedication for opioid use disorder (MOUD) is the gold standard treatment for opioid use disorder. Traditionally, "success" in MOUD treatment is measured in terms of program retention, adherence to MOUD, and abstinence from opioid and other drug use. While clinically meaningful, these metrics may overlook other aspects of the lives of people with opioid use disorder (OUD) and surprisingly do not reflect the diagnostic criteria for OUD.MethodsAuthors identified items for a pilesorting task to identify participant-driven measures of MOUD treatment success through semi-structured interviews. Interviews were transcribed verbatim and coded in Nvivo using directed and conventional content analysis to identify measures related to treatment success and quality of life goals. Participants of a low-threshold MOUD program were recruited and asked to rank identified measures in order of importance to their own lives. Multidimensional scaling (MDS) compared the similarity of items while non-metric MDS in R specified a two-dimensional solution. Descriptive statistics of participant demographics were generated in SPSS.ResultsSixteen semi-structured interviews were conducted between June and August 2020 in Philadelphia, PA, USA, and 23 measures were identified for a pilesorting activity. These were combined with 6 traditional measures for a total list of 29 items. Data from 28 people were included in pilesorting analysis. Participants identified a combination of traditional and stakeholder-defined recovery goals as highly important, however, we identified discrepancies between the most frequent and highest ranked items within the importance categories. Measures of success for participants in MOUD programs were complex, multi-dimensional, and varied by the individual. However, some key domains such as emotional well-being, decreased drug use, and attendance to basic functioning may have universal importance. The following clusters of importance were identified: emotional well-being, decreased drug use, and human functioning.ConclusionsOutcomes from this research have practical applications for those working to provide services in MOUD programs. Programs can use aspects of these domains to both provide patient-centered care and to evaluate success. Specifics from the pilesorting results may also inform approaches to collaborative goal setting during treatment.

PurposeAssisted Outpatient Treatment (AOT) programs can compel treatment-refusing individuals to participate in mental health treatment via civil court order. In California's AOT programs, individuals first must be offered 30 days of outreach services and can accept services voluntarily. This study examines the use of outreach strategies in an AOT program with the potential for voluntary or involuntary enrollment.MethodsOutreach staff completed a survey in which they reported and rated outreach strategies and barriers to treatment for 487 AOT-referred individuals.ResultsOutreach staff reported using a broad array of strategies to persuade and engage clients. Supportive and persuasive strategies were most common. More coercive strategies, including court order, were used when needed. More clients enrolled voluntarily (39.4%) than involuntarily (7.2%).ConclusionsOutreach, coupled with the strategic used of potential court involvement, can lead to voluntary enrollment of treatment-refusing individuals with many, often severe, barriers to engaging in outpatient treatment.

Should forgiveness be considered a civic virtue that promotes peace and justice following injustice? In the aftermath of conflicts as severe as state-sponsored genocide, how can relationships be restored, communities reconciled, and justice achieved? We interviewed 15 adults in Rwanda--survivors of the 1994 genocide, nominated as exemplars for their youth-serving roles in their communities and their experiences with forgiving the traumas of the genocide--about their approaches to conflict resolution, their ideas about justice and forgiveness, and their community work. Phenomenological analysis supported considering forgiveness as a civic virtue, as exemplars described a restorative approach to conflict in which justice facilitates, and is completed by, forgiveness. Implications for education emerged from exemplars' accounts, including describing a process of conflict resolution that works toward peace and justice by means of listening, uncovering the truth, acting impartially, encouraging apology and forgiveness, advising for solutions, restoring rights and relationships, and fulfilling justice.

Since 2020, people who use drugs (PWUD) experienced heightened risks related to drug supply disruptions, contamination, overdose, social isolation, and increased stress. This study explored how the lives of PWUD changed in Philadelphia over a one-year period. Using semi-structured interviews with 20 participants in a Housing First, low-barrier medication for opioid use (MOUD) program in Philadelphia, the effects of the first year of the COVID-19 pandemic on the daily lives, resources, functioning, substance use, and treatment of PWUD were explored. Interviews were analyzed using a combination of directed and conventional content analysis. Six overarching themes emerged during data analysis: (1) response to the pandemic; (2) access to MOUD and support services; (3) substance use; (4) impacts on mental health, physical health, and daily functioning; (5) social network impacts; and (6) fulfillment of basic needs. Participants reported disruptions in every domain of life, challenges meeting their basic needs, and elevated risk for adverse events. MOUD service providers offset some risks and provided material supports, treatment, social interaction, and emotional support. These results highlight how there were significant disruptions to the lives of PWUD during the first year of the COVID-19 pandemic and identified critical areas for future intervention and policies.

PurposeThe COVID-19 pandemic has dramatically affected all areas of health care. Primary care practices are on the front lines for patients seeking health care during this period. Understanding clinical and administrative staff members' strategies for managing the broad-ranging changes to primary care service delivery is important for the support of workforce well-being, burnout, and commitment to primary care.MethodsThirty-three staff members from 8 practices within a single health care system completed short, semistructured interviews from May 11, 2020 to July 20, 2020. Interviews were coded using a combination of conventional and directed content analysis.ResultsThemes emerged from the data that mapped onto the Job Demands-Control-Social Support model. Participants reported that every aspect of primary care service delivery needed to be adapted for COVID-19, which increased their job demands significantly. Several also described pride in their development of new skills, and in most interviews, they expressed that the experience brought staff together. Staff engaged in active cognitive reframing of events during the interviews as they coped with increased workplace stress. However, as the pandemic changed from an acute stress event to a chronic stressor, staff were more likely to indicate signs of burnout.ConclusionsPrimary care teams absorbed tremendous burdens during COVID-19 but also found that some stress was offset by increased support from management and colleagues, belief in their own necessity, and new development opportunities. Considering high prepandemic strain levels, the ability of primary care teams to persist under these conditions might erode as the crisis becomes an enduring challenge.

Research objectiveThe COVID-19 pandemic disrupted healthcare delivery worldwide with likely negative effects on people who use opioids (PWUO). This scoping review of the original research literature describes the impact of the COVID-19 pandemic on healthcare delivery for PWUO and identifies gaps in the literature.MethodsThis scoping review of the original research literature maps the available knowledge regarding the impact of the COVID-19 pandemic on healthcare delivery for PWUO. We utilized the methodology developed by the Joanna Briggs Institute for scoping reviews, and content analyses methodology to characterize the current state of the literature.ResultsOf the 14 included studies, administrative database (n = 11), cross-sectional (n = 1) or qualitative (n = 2) studies demonstrated service gaps (n = 7), patient/provider experiences (n = 3), and patient outcomes for PWUO (n = 4). In March 2020, healthcare utilization dropped quickly, sharply increasing only for reasons of opioid overdose by May 2020. Service gaps existed in accessing treatment for new patients during the pandemic due to capacity and infrastructure limits. Physicians reported difficulty referring patients to begin an outpatient opioid treatment program due to increased restrictions in capacity and infrastructure. Patients also reported uncertainty about accessing outpatient treatment, but that telehealth initiation of buprenorphine increased access to treatment from home. Disproportionate increases in overdose rates among African Americans were reported in two studies, with differences by race and gender not examined in most studies. Fatal overdoses increased 60% in African Americans during the pandemic, while fatal overdoses in Non-Hispanic White individuals decreased.ConclusionsIn summary, this beginning evidence demonstrates that despite early reluctance to use the healthcare system, opioid overdose-related use of healthcare increased throughout the pandemic. Service delivery for medications to treat OUD remained at or above pre-pandemic levels, indicating the ability of telehealth to meet demand. Yet, racial disparities that existed pre-pandemic for PWUO are intensifying, and targeted intervention for high-risk groups is warranted to prevent further mortality. As the pandemic progresses, future research must focus on identifying and supporting subgroups of PWUO who are at heightened risk for experiencing negative outcomes and lack of access to care.

BackgroundThe COVID-19 pandemic fundamentally changed every aspect of healthcare delivery and training. Few studies have reported on the impact of these changes on the experiences, skill development, and career expectations of medical students.MethodUsing 59 responses to a short reflection essay prompt, 3rd year medical students in Philadelphia described how the COVID-19 pandemic affected their education in mid-2020. Using conventional content analysis, six main themes were identified across 14 codes.ResultsStudents reported concerns regarding their decreased clinical skill training and specialty exposure on their career development due to the loss of in-person experience during their family medicine clerkship. A small number felt very let down and exploited by the continued high cost of tuition while missing clinical interactions. However, many students also expressed professional pride and derived meaning from limited patient and mentorship opportunities. Many students developed a new sense of purpose and a call to become stronger public health and patient advocates.ConclusionsThe medical field will need to adapt to support medical students adversely impacted by the COVID-19 pandemic, from an educational and mental health standpoint. However, there are encouraging signs that this may also galvanize many students to engage in leadership roles in their communities, to become more empathetic and thoughtful physicians, and to redesign healthcare in the future to better meet the needs of their most vulnerable patients.

The application of continuous systems improvement in medical education can provide actionable information for curriculum development, improvement, and future planning (as reported by Bowe and Armstrong, Acad Med 92:585-92, 2017). After receiving a medical education grant, we developed a curriculum to teach medical students how to use quality improvement (QI) to address health disparities in vulnerable populations. During the process of developing and implementing this curriculum, we learned several lessons.One of the major surprises was that our proposed project work took much longer to complete than anticipated. This was mainly because we did not have the right team assembled from the beginning. Specifically, we were missing a team member with evaluation expertise, and therefore we did not devise a systematic process for evaluation and assessment. Without periodic checks or timely assessments built into our curriculum design, we received feedback from students after it was too late to implement changes. We realized that our initial research design had some methodological flaws, which we later rectified.We encountered additional technical challenges during the curriculum implementation. We struggled with various online learning platforms. Through this, we learned the importance of being knowledgeable upfront about the features of learning platforms and adaptable to changing educational technologies. We also learned our curriculum could and should evolve to meet the needs of our learners and faculty. Moving forward, we realize the benefit of applying a quality improvement process to our curriculum development and implementation, which will help us to continuously transform medical education for future health care needs.

BackgroundSince their detection in 2013, Aedes aegypti has become a widespread urban pest in California. The availability of cryptic larval breeding sites in residential areas and resistance to insecticides pose significant challenges to control efforts. Resistance to pyrethroids is largely attributed to mutations in the voltage gated sodium channels (VGSC), the pyrethroid site of action. However, past studies have indicated that VGSC mutations may not be entirely predictive of the observed resistance phenotype.MethodsTo investigate the frequencies of VGSC mutations and the relationship with pyrethroid insecticide resistance in California, we sampled Ae. aegypti from four locations in the Central Valley, and the Greater Los Angeles area. Mosquitoes from each location were subjected to an individual pyrethrum bottle bioassay to determine knockdown times. A subset of assayed mosquitoes from each location was then analyzed to determine the composition of 5 single nucleotide polymorphism (SNP) loci within the VGSC gene.ResultsThe distribution of knockdown times for each of the five Californian populations sampled was non-parametric with potentially bimodal distributions. One group succumbs to insecticidal effects around 35-45 min and the second group lasts up to and beyond the termination of the assay (120+ min). We detected 5 polymorphic VGSC SNPs within the sampled California populations. One is potentially new and alternatively spliced (I915K), and four are documented and associated with resistance: F1534C, V1016I, V410L and S723T. The Central Valley populations (Clovis, Dinuba, Sanger and Kingsburg) are fairly homogenous with only 5% of the mosquitoes showing heterozygosity at any given position. In the Greater LA mosquitoes, 55% had at least one susceptible allele at any of the five SNP loci. The known resistance allele F1534C was detected in almost all sampled mosquitoes (99.4%). We also observe significant heterogeneity in the knockdown phenotypes of individuals with the identical VGSC haplotypes suggesting the presence of additional undefined resistance mechanisms.ConclusionsResistance associated VGSC SNPs are prevalent, particularly in the Central Valley. Interestingly, among mosquitoes carrying all 4 resistance associated SNPs, we observe significant heterogeneity in bottle bioassay profiles suggesting that other mechanisms are important to the individual resistance of Ae. aegypti in California.

IntroductionMedical providers' attitudes about caring for vulnerable populations have significant implications for persistent health disparities. Therefore, assessing medical students' self-perceived knowledge about community-based medicine and care for underserved populations can provide insights for improving health care delivery to achieve health equity. We evaluated third-year medical students' perceptions of their knowledge and attitudes about community medicine, and addressing health care needs of vulnerable populations.MethodsFrom October 2, 2017 to July 12, 2019, third-year medical students at a private, urban medical school were asked to complete an assessment survey during their family medicine clerkship orientation. The anonymous survey assessed students' self-perceived knowledge and attitudes regarding community medicine and care of vulnerable populations. We examined differences in survey responses by student demographics.ResultsA total of 401 students participated in the survey; 50.5% of respondents agreed that they had knowledge to assess health literacy of the patient, while only 22.2% of students agreed that they had knowledge about how to identify a community and conduct a community health needs assessment. Additionally, students agreed with being most comfortable providing care to adolescents (73.0%) and the elderly (69.5%), and that they were least comfortable caring for incarcerated individuals (31.7%) and immigrants/refugees (44.1%).ConclusionAssessment of learners' self-perceived knowledge can help highlight areas for educational interventions. Our findings suggest the need for improving medical student knowledge in areas of community health and health care for specific vulnerable populations.

Patient assault is a serious issue for the well-being of staff in psychiatric hospitals. To guide workplace responses to patient assault, more information is needed about social support from different sources and whether those supports are associated with staff well-being. The present study examines social support after patient assault from work-based and nonwork-based sources, and whether inpatient psychiatric staff desires support from them and perceive the support received as being effective. Received support across sources was examined in relations to staff well-being (physical health, mental health, anger, sleep quality) and perceptions of safety. Survey data was collected from 348 clinical staff in a large public forensic mental hospital. Among the 242 staff who reported an assault in the last year, 71% wanted support and 72% found effective support from at least one source. Generally, effective support from supervisors, coworkers, and their combination was associated with better well-being. Support from nonwork sources was related to less concerns about safety, but not to other well-being measures. However, 28% of staff did not receive effective support from any source postassault. Gaps in support as reported in this study and as found by other investigators call for systematic programming by hospital organizations to enhance the well-being of clinical staff, which in turn has implications for patient care.
