RESUMEN

The national context of deportation threat, defined as the federal government's approach to deportation and/or deportation's salience to the US public, fluctuated between 2011 and 2018. US Latinos across citizenship statuses may have experienced growing psychological distress associated with these changes, given their disproportionate personal or proximal vulnerabilities to deportation. Drawing on 8 y of public- and restricted-access data from the National Health Interview Survey (2011 to 2018), this article examines trends in psychological distress among Latinos who are US-born citizens, naturalized citizens, and noncitizens. It then seeks to explain these trends by considering two theoretical pathways through which the national context of deportation threat could distress Latinos: 1) through discrete dramatic societal events that independently signal a change to the country's approach to deportation and/or that render deportation temporarily more salient to the public or 2) through more gradual changes to the country's everyday institutional (i.e., quotidian efforts to detain and deport noncitizens) and social (i.e., deportation's ongoing salience to a concerned public) environment of deportation threat. We find that, though both pathways matter to some degree, there is more consistent evidence that the gradual changes are associated with Latino US citizens and noncitizens' overall experiences of psychological distress. The article highlights how, even absent observable spillover effects of dramatic societal events bearing on deportation threat, the institutional and social environment in which they occur implicates Latinos' well-being.

RESUMEN

At the restriction point (R), mammalian cells irreversibly commit to divide. R has been viewed as a point in G1 that is passed when growth factor signaling initiates a positive feedback loop of Cdk activity. However, recent studies have cast doubt on this model by claiming R occurs prior to positive feedback activation in G1 or even before completion of the previous cell cycle. Here we reconcile these results and show that whereas many commonly used cell lines do not exhibit a G1 R, primary fibroblasts have a G1 R that is defined by a precise Cdk activity threshold and the activation of cell-cycle-dependent transcription. A simple threshold model, based solely on Cdk activity, predicted with more than 95% accuracy whether individual cells had passed R. That a single measurement accurately predicted cell fate shows that the state of complex regulatory networks can be assessed using a few critical protein activities.

RESUMEN

BACKGROUND: The incidence of sexually transmitted infections (STIs) has been increasing in the United States, and this trend has continued alongside expanding/changing human immunodeficiency virus (HIV) prevention strategies, moving from reliance solely on behavioral interventions like condoms to biomedical methods like oral and injectable antiretroviral preexposure prophylaxis (PrEP). In 2019, the Ending the HIV Epidemic (EHE) initiative was released to prioritize resource allocation to the 50 jurisdictions in the United States with the highest HIV incidence, providing an opportunity to monitor STI incidence in a national group of discrete, geographic units and identify trends and differences across jurisdictions. OBJECTIVES AND DESIGN: Using existing data from the US CDC and Census Bureau, a retrospective analysis was conducted to examine the incidence of STIs in 49 of the 50 EHE priority counties between 2005 and 2019. This timeframe was divided into 2 periods representing a before and after entry into the biomedical era of HIV prevention: P1 (2005-2011) and P2 (2012-2019). KEY RESULTS: A total of 49 EHE counties were included in this analysis, representing 27.4% of the total US population. Entry into the biomedical HIV prevention era was associated with an increase in STI incidence in 28 EHE counties and a decrease in 14 EHE counties. The greatest percent increase in total STI incidence was in the District of Columbia (+12.1%; incidence rate ratio = 1.121 [1.115, 1.127]; P < 0.001) and the greatest percent decrease was identified in Orleans Parish, LA (-8.7%; incidence rate ratio = 0.913 [0.908, 0.919]; P < 0.001). CONCLUSIONS: Rising STI rates in the biomedical era of HIV prevention represent missed opportunities for comprehensive sexual and preventive healthcare. County-level data provide actionable insight for reducing STI incidence. The EHE counties that have experienced decreases in STI incidence while being in the biomedical era may provide models of best practice, which may be scaled in other jurisdictions.

RESUMEN

A hydrostatic skeleton allows a soft body to transmit muscular force via internal pressure. A human's tongue, an octopus' arm and a nematode's body illustrate the pervasive presence of hydrostatic skeletons among animals, which has inspired the design of soft engineered actuators. However, there is a need for a theoretical basis for understanding how hydrostatic skeletons apply mechanical work. We therefore modeled the shape change and mechanics of natural and engineered hydrostatic skeletons to determine their mechanical advantage (MA) and displacement advantage (DA). These models apply to a variety of biological structures, but we explicitly consider the tube feet of a sea star and the body segments of an earthworm, and contrast them with a hydraulic press and a McKibben actuator. A helical winding of stiff, elastic fibers around these soft actuators plays a critical role in their mechanics by maintaining a cylindrical shape, distributing forces throughout the structure and storing elastic energy. In contrast to a single-joint lever system, soft hydrostats exhibit variable gearing with changes in MA generated by deformation in the skeleton. We found that this gearing is affected by the transmission efficiency of mechanical work (MA×DA) or, equivalently, the ratio of output to input work. The transmission efficiency changes with the capacity to store elastic energy within helically wrapped fibers or associated musculature. This modeling offers a conceptual basis for understanding the relationship between the morphology of hydrostatic skeletons and their mechanical performance.

RESUMEN

BACKGROUND: Sex workers, those who trade sex for monetary or nonmonetary items, experience high rates of HIV transmission but have not been adequately included in HIV prevention and Pre-Exposure Prophylaxis (PrEP) adherence program development research. Community-empowered (C.E.) approaches have been the most successful at reducing HIV transmission among sex workers. Centering Healthcare (Centering) is a C.E. model proven to improve health outcomes and reduce health disparities in other populations, such as pregnant women, people with diabetes, and sickle cell disease. However, no research exists to determine if Centering can be adapted to meet the unique HIV prevention needs of sex workers. OBJECTIVE: We aim to explain the process by which we collaboratively and iteratively adapted Centering to meet the HIV prevention and PrEP retention needs of sex workers. METHODS: We utilized the Assessment, Decision, Adaptation, Production, Topical Experts, Integration, Training, Testing (ADAPT-ITT) framework, a model for adapting evidence-based interventions. We applied phases one through six of the ADAPT-ITT framework (Assessment, Decision, Adaptation, Production, Topical Experts, Integration) to the design to address the distinct HIV prevention needs of sex workers in Chicago. Study outcomes corresponded to each phase of the ADAPT-ITT framework. Data used for adaptation emerged from collaborative stakeholder meetings, individual interviews (n = 36) and focus groups (n = 8) with current and former sex workers, and individual interviews with care providers (n = 8). In collaboration with our community advisory board, we used a collaborative and iterative analytical process to co-produce a culturally adapted 3-session facilitator's guide for the Centering Pre-exposure Prophylaxis (C-PrEP +) group healthcare model. RESULTS: The ADAPT-ITT framework offered structure and facilitated this community-empowered innovative adaptation of Centering Healthcare. This process culminated with a facilitator's guide and associated materials ready for pilot testing. CONCLUSIONS: In direct alignment with community empowerment, we followed the ADAPT-ITT framework, phases 1-6, to iteratively adapt Centering Healthcare to suit the stated HIV Prevention and PrEP care needs of sex workers in Chicago. The study represents the first time the first time Centering has been adapted to suit the HIV prevention and PrEP care needs of sex workers. Addressing a gap in HIV prevention care for sex workers, Centering PrEP harnesses the power of community as it is an iteratively adapted model that can be piloted and replicated regionally, nationally, and internationally.

RESUMEN

Reef-building crustose coralline algae (CCA) are known to facilitate the settlement and metamorphosis of scleractinian coral larvae. In recent decades, CCA coverage has fallen globally and degrading environmental conditions continue to reduce coral survivorship, spurring new restoration interventions to rebuild coral reef health. In this study, naturally produced chemical compounds (metabolites) were collected from two pantropical CCA genera to isolate and classify those that induce coral settlement. In experiments using four ecologically important Caribbean coral species, we demonstrate the applicability of extracted, CCA-derived metabolites to improve larval settlement success in coral breeding and restoration efforts. Tissue-associated CCA metabolites induced settlement of one coral species, Orbicella faveolata, while metabolites exuded by CCA (exometabolites) induced settlement of three species: Acropora palmata, Colpophyllia natans and Orbicella faveolata. In a follow-up experiment, CCA exometabolites fractionated and preserved using two different extraction resins induced the same level of larval settlement as the unfractionated positive control exometabolites. The fractionated CCA exometabolite pools were characterized using liquid chromatography tandem mass spectrometry, yielding 145 distinct molecular subnetworks that were statistically defined as CCA-derived and could be classified into 10 broad chemical classes. Identifying these compounds can reveal their natural prevalence in coral reef habitats and facilitate the development of new applications to enhance larval settlement and the survival of coral juveniles.

RESUMEN

Hepatitis C virus infection (HCV) is prevalent in prisons. Therefore, effective prison HCV services are critical for HCV elimination programmes. We aimed to evaluate the efficacy of a regional HCV prison testing and treatment programme. Between July 2017 and June 2022, data were collected prospectively on HCV test offer and uptake rates, HCV Antibody (HCV-Ab) and HCV-RNA positivity, treatment starts and outcomes for new inmates incarcerated in three prisons. Rates of HCV-Ab and RNA positivity at reception, incidence of new HCV infections and reinfection following treatment were determined. From a total of 39,652 receptions, 33,028 (83.3%) were offered HCV testing and 20,394 (61.7%) completed testing. Including all receptions, 24.5% of tests (n = 4995) were HCV-Ab positive and 8.4% of tests (n = 1713) were HCV-RNA positive. When considering the first test for each individual (median age 34 years; 88.1% male), 14.8% (n = 1869) and 7.2% (n = 905) were HCV-Ab and HCV-RNA positive, respectively. The incidence of new HCV-Ab and RNA positivity was 5.1 and 3.3 per 100 person-years, respectively. Of 1145 HCV viraemic individuals, 18 died within 6 months and 150 were rapidly transferred out of area, leaving 977 individuals with outcomes. Of these, 835 (85.5%) received antivirals and 47 spontaneously cleared the infection, leaving 95 (9.7%) untreated. 607 (72.7%) achieved SVR. 95 patients had reinfection post-treatment (rate 10.1 cases per 100 person-years). Testing for HCV has increased in our prisons and the majority with viraemia are initiated on antiviral treatment. Reassuringly, a significant fall in frequency of HCV-RNA positivity at prison reception was observed suggesting progress towards HCV elimination.

RESUMEN

Inhibitors of Bruton tyrosine kinase (BTK) and phosphatidylinositol 3-kinase δ (PI3Kδ) that target the B-cell receptor (BCR) signaling pathway have revolutionized the treatment of chronic lymphocytic leukemia (CLL). Mutations associated with resistance to BTK inhibitors have been identified, but limited data are available on mechanisms of resistance to PI3Kδ inhibitors. Here we present findings from longitudinal whole-exome sequencing of cells from patients with multiply relapsed CLL (N = 28) enrolled in trials of PI3K inhibitors. The nonresponder subgroup was characterized by baseline activating mutations in MAP2K1, BRAF, and KRAS genes in 60% of patients. PI3Kδ inhibition failed to inhibit ERK phosphorylation (pERK) in nonresponder CLL cells with and without mutations, whereas treatment with a MEK inhibitor rescued ERK inhibition. Overexpression of MAP2K1 mutants in vitro led to increased basal and inducible pERK and resistance to idelalisib. These data demonstrate that MAPK/ERK activation plays a key role in resistance to PI3Kδ inhibitors in CLL and provide a rationale for therapy with a combination of PI3Kδ and ERK inhibitors.

RESUMEN

Cusatuzumab is a high-affinity, anti-CD70 monoclonal antibody under investigation in acute myeloid leukemia (AML). This two-part, open-label, multicenter, phase I/II trial evaluated cusatuzumab plus azacitidine in patients with newly diagnosed AML ineligible for intensive chemotherapy. Patients received a single dose of cusatuzumab at one of four dose levels (1, 3, 10, or 20 mg/kg) 14 days before starting combination therapy. In phase I dose escalation, cusatuzumab was then administered on days 3 and 17, in combination with azacitidine (75 mg/m2) on days 1-7, every 28 days. The primary objective in phase I was to determine the recommended phase II dose (RP2D) of cusatuzumab plus azacitidine. The primary objective in phase II was efficacy at the RP2D (selected as 10 mg/kg). Thirty-eight patients were enrolled: 12 in phase I (three per dose level; four with European LeukemiaNet 2017 adverse risk) and 26 in phase II (21 with adverse risk). An objective response (≥partial remission) was achieved by 19/38 patients (including 8/26 in phase II); 14/38 achieved complete remission. Eleven patients (37.9%) achieved an objective response among the 29 patients in phase I and phase II treated at the RP2D. At a median follow-up of 10.9 months, median duration of first response was 4.5 months and median overall survival was 11.5 months. The most common treatment-emergent adverse events were infections (84.2%) and hematologic toxicities (78.9%). Seven patients (18.4%) reported infusion-related reactions, including two with grade 3 events. Thus, cusatuzumab/azacitidine appears generally well tolerated and shows preliminary efficacy in this setting. Investigation of cusatuzumab combined with current standard-of-care therapy, comprising venetoclax and azacitidine, is ongoing.

RESUMEN

INTRODUCTION: HIV incidence remains high in the U.S. as do disparities in new HIV diagnosis between White and Black populations and access to preventive therapies like pre-exposure prophylaxis (PrEP). The federal Ending the HIV Epidemic (EHE) initiative was developed to prioritize resources to 50 jurisdictions with high HIV incidence. METHODS: We conducted secondary analyses of data (2013-2019) from the CDC, Census Bureau, and AIDSVu to evaluate the correlation between PrEP use, HIV incidence, and HIV incidence disparities. We compared the PrEP-to-need ratio (PnR) with the ratio of Black and White HIV incidence rates in 46 EHE counties. Subsequent analyses were performed for the seven states that contained multiple EHE counties. RESULTS: These 46 counties represented 25.9% of the U.S. population in 2019. HIV incidence ranged from 10.5 in Sacramento County, CA, to 59.6 in Fulton County, GA (per 100,000). HIV incidence disparity ranged from 1.5 in Orleans Parish, LA, to 12.1 in Montgomery County, MD. PnR ranged from 26.8 in New York County, NY, to 1.46 in Shelby County, TN. Change in HIV incidence disparities and percent change in PnR were not significantly correlated (ρ = 0.06, p = 0.69). Change in overall HIV incidence was significantly correlated with increase in PnR (ρ = -0.42, p = 0.004). CONCLUSIONS: PrEP has the potential to significantly decrease HIV incidence; however, this benefit has not been conferred equally. Within EHE priority counties, we found significant HIV incidence disparities between White and Black populations. PrEP has decreased overall HIV incidence, but does not appear to have decreased HIV incidence disparity.

RESUMEN

OBJECTIVE: The objective of this study was to assess women's healthcare providers' treatment practices for pregnant women with migraine. BACKGROUND: Migraine is associated with several maternal and fetal complications during pregnancy, including preeclampsia and preterm birth. Migraine treatment during pregnancy can present significant challenges due to lack of controlled clinical trials and risks associated with specific medications. METHODS: Women's healthcare providers were queried regarding practice patterns and comfort with use of acute and preventive migraine treatments during pregnancy. The survey was distributed online. RESULTS: The survey was completed by 92 women's healthcare providers (response rate 22.9% [92/402]), with most specializing in general obstetrics and gynecology (91% [83/92]). Approximately one-fourth (26% [24/92]) of respondents indicated they counseled women on migraine treatment in pregnancy as early as before pregnancy contemplation, while over one-third (35% [32/92]) counseled on migraine treatment once the patient became pregnant. The majority of respondents reported feeling somewhat or very comfortable with recommending (63% [58/92]) or continuing (64% [59/92]) acute treatments for pregnant patients with migraine, with highest comfort levels for acetaminophen (100% [92/92] for prescribing or continuing) and caffeine (94% [85/90] prescribing, 91% [82/90] continuing). Higher levels of discomfort were reported with triptans (88% [80/91] rarely or never prescribe during pregnancy). Survey respondents felt less comfortable with recommending preventive migraine treatments to pregnant patients (40% [37/92] somewhat or very comfortable), compared with a higher comfort level with continuing preventive medications (63% [58/92] somewhat or very comfortable). Highest comfort levels were reported with use of magnesium (69% [63/91] comfortable prescribing, 82% [75/92] comfortable continuing) and non-pharmacologic approaches (70% [62/89] comfortable prescribing, 84% [75/89] comfortable continuing). Nearly 40% (35/92) of respondents reported that they typically refer to neurologists or headache specialists for migraine treatment during pregnancy. CONCLUSION: This survey of women's healthcare providers revealed varying levels of comfort regarding migraine management during pregnancy, and highlights the need for additional education regarding migraine treatment safety data during pregnancy.

RESUMEN

BACKGROUND: Ciswomen constitute a disproportionately low percentage of pre-exposure prophylaxis for HIV prevention (PrEP) users compared to men. Despite PrEP's effectiveness, women are 5.25 times less likely to take PrEP than men. Identifying women who have increased reasons for HIV prevention and educating and offering PrEP to these women is crucial to reducing HIV transmission and overall health equity. However, the best method of identifying women at highest risk of acquiring HIV remains unknown. This study aimed to identify common HIV risk factors and data sources for identifying these common factors (e.g., electronic medical record data, open source neighborhood data), as well as potential intervention points and missed opportunities for PrEP linkage. METHODS: We conducted an evaluation of multiple data sources: semi-structured qualitative interviews, electronic medical record (EMR) chart abstraction, and open source data abstraction. We accessed EMRs for enrolled participants and all participants signed a standard release of medical information (ROI) form for all institutions at which they had received medical care for the five-year period preceding their HIV diagnosis. Data were abstracted using a standardized procedure. Both structured and unstructured fields (i.e., narrative text of free notes) within the EMR were examined and included for analysis. Finally, open data sources (e.g., STI cases, HIV prevalence) were examined by community area of Chicago. Open data sources were used to examine several factors contributing to the overall Economic Hardship Index (EHI) score. We used these calculated scores to assess the economic hardship within participants' neighborhoods. RESULTS: A total of 18 cisgender women with HIV participated in our study. Participants were mostly Black/African American (55.6%) and young (median age of 34). Our analysis identified two main themes influencing HIV risk among participants: contextual factors and relationship factors. Further, potential pre-diagnosis intervention points and missed opportunities were identified during reproductive health/prenatal visits, behavioral/mental health visits, and routine STI testing. Our evaluation of multiple data sources included investigating the presence or absence of information in the EMR (STI history, HIV testing, substance use, etc.) as well as whether pertinent information could be gathered from open access sources. CONCLUSION: Ciswomen recently diagnosed with HIV identified many shared experiences, including syndemic conditions like mental illness and substance abuse, sex with men who have sex with men, and frequent moving in areas with high HIV incidence prior to their diagnosis. It is imperative that providers ask patients about social history, information about partners, and other key variables, in addition to the standardized questions. Findings can be used to better recognize ciswomen most vulnerable to HIV and offer PrEP to them, reducing HIV transmission.

RESUMEN

BACKGROUND: Expanding pre-exposure prophylaxis (PrEP) among transgender women in the United States is an important strategy to meet national HIV prevention goals, however self-reported use of PrEP is low in this group. METHODS: This study reports the findings of a cross-sectional analysis of the relationship of barriers as well as facilitators to recent PrEP use among transgender women enrolled in an evaluation of the TransLife Care project (Chicago, Illinois), a structural intervention designed to meet basic needs. We computed multivariable prevalence ratios for barriers, facilitators and recent PrEP use, controlling for demographics. RESULTS: Findings suggest that psychosocial and structural barriers, including moderate/high alcohol use, stimulant use, and history of incarceration were all positively associated with recent PrEP use among urban transgender women. In addition, a psychosocial facilitator, gender affirmation, was positively associated with recent PrEP use, while, while collective self-esteem, a was negatively associated with it. Finally, common indications for PrEP have high sensitivity, but low specificity and predictive value for identifying those on PrEP. CONCLUSION: We conclude that despite a large gap in PrEP use among those with indications, individuals experiencing psychosocial and structural barriers are more likely to use PrEP, and facilitators, such as psychological sense of affirmed gender may support its use.

RESUMEN

BACKGROUND: HIV seroprevalence in Nigeria is increasing among men who have sex with men (MSM) from 14% to 2007 to 23% in 2014, threatening progress towards ending the epidemic in the country. Expanding access to HIV testing and linkage to care for key populations, like young MSM (YMSM), is critical to end the HIV epidemic in Nigeria. The Intensive Combination Approach to Roll Back the Epidemic in Nigerian Adolescents (iCARE Nigeria) pilot intervention successfully implemented a combination of evidence-based interventions utilizing peer navigators and popular social media apps and platforms to reach young men at risk for HIV exposure, including YMSM. We conducted sequential mixed methods explanatory implementation research to expand on the previously reported effectiveness and implementation outcomes and to explore the determinants and strategies which contributed to primary study results. METHODS: We conducted key informant interviews and focus group discussions with 2 peer navigators and 3 study staff at the end of the pilot. We used directed content analysis to understand the quantitative results from the pilot. Using the Implementation Research Logic Model, we were able to identify and map strategies through mechanisms of action from barriers addressed to the reported implementation outcomes including feasibility, acceptability fidelity and adoption. RESULTS: We found that iCARE Nigeria's pilot intervention implementers reported high feasibility, acceptability fidelity and adoption were associated with implementation of strategies which addressed many challenging contextual factors, including social stigma, online social networking, legal barriers surrounding MSM behavior, and the COVID-19 pandemic. These strategies included integration of stakeholders' interests, selection of experienced peer navigators including from the targeted population, training and supportive supervision using an implementation guide, ensuring safety (COVID and legal) and identification of clinics serving the targeted population. CONCLUSION: Mixed methods using implementation research frameworks provided insights into the strategies and barriers and facilitators they addressed which may explain the success of the pilot. These results can inform strategies needed to scale-up the intervention to youth including YMSM in other areas in Nigeria and the region.

RESUMEN

INTRODUCTION: Alopecia areata (AA) is a nonscarring alopecia with an estimated global prevalence of 2% and limited data on the efficacy of current treatment. Clinical practice guidelines (CPGs) provide recommendations based on best available evidence. It is unclear how many AA CPGs are available globally. AIM: To systematically search for and identify CPGs on AA and to critically appraise their quality using validated tools. METHODS: We performed a literature search to identify CPGs published between October 2014 and April 2021, using the following databases: MEDLINE, Embase, National Institute for Health and Care Excellence (NICE), Guidelines International Network, Emergency Care Research Institute guidelines trust, Australian CPGs, Turning Research Into Practice database and DynaMed. The systematic review was conducted and reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses framework. Three critical appraisal tools were used: Appraisal of Guidelines for Research and Evaluation (AGREE) II instrument, Lenzer's red flags and United States Institute of Medicine's (IOM) criteria of trustworthiness. RESULTS: In total, six AA CPGs from seven manuscripts (one CPG was in two parts published in separate papers) were included. The majority (four of six) of the CPGs focused on treatment. Four CPGs (total of five papers) were in English and two CPGs were only available in the original language (one Russian and one Japanese). All AA CPGs demonstrated low quality in several domains in the AGREE II appraisal, including stakeholder involvement and applicability, with the latter being deemed the worst domain for all CPGs, with an average of 29%. The mean (SD) number of Lenzer's red flags for the included CPGs was 3.4 (1.5) out of a total of 8 possible red flags, while the IOM criteria showed 1.6 (0.8) 'fully met' criteria and 3.1 (1.2) 'not met' out of a total of 9 criteria. CONCLUSION: We found a limited number of AA CPGs, all of which had significant methodological deficiencies. We encourage guideline development groups to use validated checklists/tools to develop reliable and trustworthy CPGs.

RESUMEN

Despite numerous available psoriasis treatments, no "one size fits all" regimen provides complete disease control without side effects, logistical obstacles, and/or expense. Despite increasingly efficacious drugs, only 20-25% of patients treated with biologic therapies achieve completely clear skin (PASI 100) and even fewer achieve this if they have experienced failures of multiple biologics.

RESUMEN

Persons who are incarcerated (PWAI) suffer from a disproportionately higher number of physical and mental health conditions. While most jails and prisons provide onsite healthcare, community correctional centers often do not and accessing community healthcare is challenging due to insurance issues, inadequate health literacy, mistrust, and long waits for appointments. A registered nurse-led wellness clinic provides a viable solution to addressing the healthcare needs of PWAI in a community correctional setting. Through a community-academic partnership between a college of nursing and two community correctional transitional centers for men, a registered nurse (RN) faculty member and nursing students provide onsite healthcare. Services include, but are not limited to, acute and chronic disease management, case management, healthcare navigation, and health education. In the first 2 years of operation, there have been 587 new resident health assessments, 882 RN visits, and 152 group education sessions. RN visits have been primarily for: connection to resources (42.6%), medication management (15.6%), and acute conditions (12%). A RN-led wellness clinic is an innovative way to address health needs for PWAI. While this model of care focuses on an academic RN faculty practice at community correctional centers it could be replicated across community settings.

RESUMEN

Caudal cervical articular process joint osteoarthritis (CAPJ OA) leads to career-altering clinical signs in the horse. Oblique radiographs and standing cone beam computed tomography (CBCT) facilitate the assessment of this area, however, the variability of interpretation of these images is currently unknown. This retrospective, secondary analysis, methods comparison study investigated interobserver agreement between clinicians and modality in grades of CAPJ OA on lateral and oblique radiographs and CBCT. We hypothesized that agreement between clinicians' grades of CAPJ OA would be lowest for oblique radiographs and highest for CBCT, and agreement between grades of CAPJ OA would be low for all pairs of modalities. Horses underwent lateral and oblique radiography and CBCT of the CAPJs of C5-C6 and C6-C7. Radiographs and CBCT images were graded retrospectively by four blinded clinicians using 3-point scales. Cohen's kappa analysis was used to evaluate interobserver agreement between grades of CAPJ OA, and agreement between grades of CAPJ OA between different modalities was explored using kappa-weighted analysis. Agreement between clinicians' grades of CAPJ OA was moderate for lateral radiographs (0.49), and fair for oblique radiographs (0.23) and CBCT (0.36). For all modalities, agreement was slight to fair between clinicians for CAPJs with grade 1 (normal, 0.21-0.32) or 2 (mild, 0.13-0.36) CAPJ OA, and moderate to substantial for grade 3 (moderate to severe, 0.45-0.77) CAPJ OA. Agreement between grades of CAPJ OA was fair for all pairs of modalities. This study provides important information regarding the inconsistency of interpretation of mild CAPJ OA on radiographs and CBCT amongst clinicians.

RESUMEN

INTRODUCTION: Many Australian Defence Force (ADF) and Veteran families are affected by the stressors of Defence family life, including frequent and prolonged parental deployments, and frequent relocations. OBJECTIVE: To address a gap in information about Defence and Veteran (hereafter Defence) parents' knowledge, confidence and resources to support their young children's well-being and build their resilience. DESIGN: This study used a mixed methods design to explore Defence parent's perceptions of their young children's (aged 2-8 years) social and emotional well-being and understanding of their children's responses to unique stressors as well as their confidence in providing support. Data from 41 parents were available. FINDINGS: Overall, parents reported positive well-being evaluation of their children. However, just over a third of parents also reported that their children rarely cope well on two indicators combined (adapting to new situations and sharing negative emotions with others). Significantly, more than half of the parents (61%) were only partially confident in their ability to assist their children to cope with unique stressors in military families. Qualitative data provided further insights into children's struggle with relocations and parental absence and the challenges parents face in supporting them. Parents reported having limited access to effective age- and culturally appropriate resources to support their young children. DISCUSSION: In a first-of-its kind study, we found that Australian Defence parents reported their young children were coping on most of the key well-being indicators. However, awareness of currently available supports for children remains a barrier as well as access to contextualised, age- and culturally appropriate resources are lacking. CONCLUSION: There is a need for access to free, quality, online, research-based Australian resources to support young children from Defence families, especially for those living in regional and rural locations and are less likely to have access to mental health and other specialist supports.

RESUMEN

Point of care ultrasound (POCUS) has the potential to improve healthcare outcomes and is increasingly used in veterinary primary care and specialty practice. The aim of this study was to evaluate a self-driven POCUS learning program during clinical rotations in a large animal teaching hospital. A randomized controlled trial of 94 students evaluated the hypotheses that access to a self-driven POCUS program would improve scores on a written test and the quality of subjective, objective, assessment and plan (SOAP) documents. Use of the POCUS devices and perceptions of veterinary students towards POCUS were analyzed. The self-driven POCUS learning program was feasible, and the perception of most students (94%) was that the program was useful for their education. Access to equipment, ability to scan individually, the hands-on learning aspect, and clinicians' help were the most valued aspects of the program. Earlier access to POCUS in the curriculum, hands-on tutorials/labs, and a more structured learning program were identified by students as aspects to improve. Access to the self-driven POCUS program resulted in significantly higher scores on the written test in a subpopulation of students with lower scores. No significant differences in results on the multiple-choice tests in the subpopulation with higher scores or in SOAP scores of the complete group or subpopulations were found. A self-driven POCUS learning program was perceived as beneficial by students, increased POCUS knowledge in students with lower test scores, and was possible to implement in a busy large animal teaching hospital.
