Perinatal Health Outcomes Among Women on Community Supervision: A Scoping Review.

The purpose of this scoping review is to review the extant literature regarding perinatal health outcomes for women on community supervision in the United States. PubMed, CINAHL, Scopus, PsycINFO, and Public Health were searched for peer-reviewed articles published in the United States from January 1, 1970, to March 7, 2023. After removal of duplicates and review of 1,412 article titles and abstracts, 19 articles were retrieved for full-text review; this yielded 4 studies for inclusion. Studies range in size from 10 to 292 participants (N = 405) and only two reported geographic locations. Three studies comprised probation or parole and two studies included court-mandated treatment for substance use. All studies examined outcomes during the postpartum period, such as mood disorder or substance use severity. No studies evaluated the health of women during pregnancy and/or childbirth. To enhance health equity and reduce maternal morbidity and mortality among women on community supervision, more inclusive research that examines health outcomes during the perinatal period is needed. Furthermore, there must be interventions that address the social determinants of health, racial and systemic discrimination, socioeconomic barriers, and violence that are often experienced among women with criminal justice system involvement.

Method for assessing coating uniformity of angioplasty balloons coated with poly(lactic-co-glycolic acid) nanoparticles loaded with quercetin.

In this study, we aim to quantify coating uniformity and correlate fluorescence intensity to drug loading for drug-coated angioplasty balloons (DCB) coated with 5, 10, 15, or 20 layers of poly(lactic-co-glycolic acid) nanoparticles (NPs) entrapped with quercetin. Uniformity was quantified from histograms and horizontal line profiles of microscopic fluorescent images acquired with sample specific parameters, and cracks in the coating were measured and counted. The fluorescence of images acquired with global parameters was correlated with quercetin loading measured via gravimetric/HPLC analysis. More layers on DCBs may be associated with less uniform coatings, as indicated by differences in histogram standard deviations. The line profile percent deviation from average for each sample was <20%. Cracks were present on all balloons, but their length was not significantly different between samples. The 5-layer DCBs had the fewest cracks, whereas the 15-layer DCBs had the most cracks. A strong positive correlation (R = 0.896) was identified between fluorescence intensity and drug loading. A relationship between the number of layers and coating uniformity seems to exist, but further investigations are required for confirmation. Fluorescence intensity appears to strongly predict drug loading, demonstrating that fluorescent imaging may be a viable alternative to drug release studies.

Scaling Emergency Department Opioid Use Disorder Treatment Across California to Reduce Overdose Deaths, 2019-2023.

Since April 2019, CA Bridge has worked with emergency departments (EDs) in diverse geographic and emergency care settings across California to scale up low-threshold buprenorphine access, patient navigation programs, harm reduction services, and take-home naloxone. Between April 2019 and June 2023, 268 (81.0%) of 331 acute care hospitals in California received funding and technical assistance from CA Bridge and completed data reporting. These hospitals provided navigation services during 279 025 patient encounters and gave patients buprenorphine in 89 549 ED visits. (Am J Public Health.

Associations of Sleep Deficiency With Sexual Risk Behaviors and HIV Treatment Outcomes Among Men Who Have Sex With Men Living With or at High Risk of Acquiring HIV.

BACKGROUND: Associations of sleep deficiency and methamphetamine use with sexual health and HIV treatment outcomes are poorly understood. SETTING: A longitudinal cohort of men who have sex with men at risk for or living with HIV (the mSTUDY) was analyzed. This analysis included 1445 study visits among 382 participants. Data were collected from June 2018 to February 2022. METHODS: Semiannual study visits included self-interviews for sleep deficiency, sexual behaviors, substance use, and HIV treatment. Sleep deficiency was measured using the Pittsburgh Sleep Quality Index. Participants provided specimens for HIV viral load and sexually transmitted infection (STI) testing (chlamydia, gonorrhea, syphilis). Associations between sleep deficiency and STI/HIV outcomes were estimated using multiple logistic regression. RESULTS: Across visits, the prevalence of sleep deficiency was 56%, with 33% reporting methamphetamine use and 55% living with HIV. Sleep deficiency was associated with reporting at least 1 new anal sex partner (aOR = 1.62, 95% CI: 1.21 to 2.15), exchange sex (aOR = 2.71, 95% CI: 1.15 to 6.39), sex party attendance (aOR = 2.60, 95% CI: 1.68 to 4.04), and missing HIV medications (aOR = 1.91, 95% CI: 1.16 to 3.14). The association between sleep deficiency and exchange sex differed for participants who did and did not report the use of methamphetamine (P = 0.09). CONCLUSION: Sleep deficiency was associated with sexual health and HIV treatment behaviors after accounting for methamphetamine use. Sleep health should be considered in STI/HIV prevention, particularly for those who use methamphetamine.

Using the Novel Musculoskeletal Emergency Medicine Assessment Tool: A Feasibility Study.

Background and objective While musculoskeletal (MSK) disorders account for a significant number of primary care and emergency department (ED) visits, there are widely recognized shortcomings and gaps in MSK education throughout medical training. Undergraduate medical education (UME) frequently fails to impart clinically relevant MSK knowledge, while many emergency medicine (EM) residency graduates report feeling unprepared to manage MSK complaints. Existing MSK assessments are not tailored to EM and may inaccurately assess specialty-specific MSK knowledge. The novel validated Musculoskeletal Emergency Medicine Assessment Tool (MEAT) holds great promise in standardizing EM MSK knowledge assessment. This trial of feasibility was conducted to assess the viability and practicality of using MEAT to evaluate MSK knowledge among incoming resident physicians in EM programs. Methods This feasibility study involved 21 incoming EM resident physicians from two programs at a single institution. MEAT was administered online during orientation, and demographic data and survey metadata were collected. UME MSK education details were obtained, and MEAT scores were analyzed. Results Participants reported no difficulties in accessing or understanding the 50-question online MEAT, resulting in a 100% response rate. The average pretest score for all interns was 29.9, with a median of 30. Most participants had documented UME MSK education, but curricular content varied widely. The participants took an average of 32 minutes to complete the assessment. Conclusions MEAT demonstrated successful implementation and high response rates, suggesting a high level of feasibility. The tool can be used to assess baseline MSK knowledge and ultimately track progression during residency with the potential for evaluating educational interventions once further validation studies have been performed. Further adoption of MEAT across multiple EM residency programs will help to enhance the tool's generalizability.

Development and National Validation of a Musculoskeletal Emergency Medicine Assessment Tool.

Introduction Musculoskeletal (MSK) complaints and injuries are the fourth most common primary diagnosis in the emergency department in the United States (US). Despite the prevalence and economic impact on the US healthcare system, new emergency medicine (EM) residency graduates report feeling unprepared to treat MSK complaints. Currently, there are no reported means to assess MSK knowledge in EM resident physicians. The purpose of this study is to develop a validated and peer-reviewed multiple-choice assessment tool focused on MSK knowledge relevant to EM to allow us to better assess the knowledge of resident physicians. Methods A group of EM/Sports Medicine subject-matter experts (SMEs) created an initial list of the most important MSK topics in EM to generate a relevant question bank. The questions were validated by a different group of SMEs using a three-round modified Delphi method to obtain consensus on the importance of each question. Based on these results, the assessment was formed. Results From a list of 99 MSK topics, SMEs developed a final list of 37 MSK topics relevant to EM. Following round one, free-marginal kappa was 0.58, 95% CI [0.50, 0.66], with a moderate overall agreement of 71.95%. Following round two, the calculated free-marginal kappa increased to 0.88, 95% CI [0.83, 0.92], with an overall agreement of 91.79%. Using a five-point Likert scale, a threshold of an average score less than four was used to exclude questions in round three of validation and to create a final 50-question assessment tool. Conclusion Our proposed exam, titled Musculoskeletal Emergency Medicine Assessment Tool (MEAT), was successfully validated by experts in our field. It evaluates clinically important topics and offers a tool for assessing MSK knowledge in EM resident physicians. Future studies are needed to determine the feasibility of administering the tool and to establish a baseline score among different populations within the practicing field of EM.

An intervention development study of an mHealth app to manage women's health and safety while on probation.

PURPOSE: Preliminary studies have suggested that women are responsive to using technology to manage their health, due to its discreet, convenient, and cost-effective nature. Yet, there are limited mobile health (mHealth) apps specific to women's needs, particularly those on probation. The purpose of this study was to explore features of 2 existing mHealth applications related to sexual health and safety, specific to interpersonal and sexual violence, to answer research questions related to the usability, barriers, and facilitators of mHealth app use for women on probation. SUBJECTS: We purposefully sampled from a local adult probation site and utilized snow-ball sampling to recruit 11 women who were on probation and owned iPhones. METHODS: We conducted an exploratory intervention development study using a qualitative design. Social Cognitive Theory was used for data synthesize and organization. FINDINGS: Three themes emerged: (1) It made me take time for myself; (2) It helped me to be more respectful of my body; (3) The connectivity….that was helpful. MAJOR IMPLICATIONS: Participants expressed mHealth apps to be usable, feasible, accessible and promoted self-efficacy by allowing them track symptoms and patterns of behavior specific to health and safety in a discreet, convenient, and effective manner. This research suggests that a culturally tailored mHealth app may be an appropriate intervention to provide timely gender-responsive feedback, resources, and health care to women on probation.

Assessing breast arterial calcification in mammograms and its implications for atherosclerotic cardiovascular disease risk.

PURPOSE: Breast arterial calcifications (BAC) are incidentally observed on mammograms, yet their implications remain unclear. We investigated lifestyle, reproductive, and cardiovascular determinants of BAC in women undergoing mammography screening. Further, we investigated the relationship between BAC, coronary arterial calcifications (CAC) and estimated 10-year atherosclerotic cardiovascular (ASCVD) risk. METHODS: In this cross-sectional study, we obtained reproductive history and CVD risk factors from 215 women aged 18 or older who underwent mammography and cardiac computed tomographic angiography (CCTA) within a 2-year period between 2007 and 2017 at hospital. BAC was categorized as binary (present/absent) and semi-quantitatively (mild, moderate, severe). CAC was determined using the Agatston method and recorded as binary (present/absent). Adjusted odds ratios (ORs) and 95 % confidence intervals (CIs) were calculated, accounting for age as a confounding factor. ASCVD risk over a 10-year period was calculated using the Pooled Cohort Risk Equations. RESULTS: Older age, systolic and diastolic blood pressures, higher parity, and younger age at first birth (≤28 years) were significantly associated with greater odds of BAC. Women with both BAC and CAC had the highest estimated 10-year risk of ASCVD (13.30 %). Those with only BAC (8.80 %), only CAC (5.80 %), and no BAC or CAC (4.40 %) had lower estimated 10-year risks of ASCVD. No association was detected between presence of BAC and CAC. CONCLUSIONS: These findings support the hypothesis that BAC on a screening mammogram may help to identify women at potentially increased risk of future cardiovascular disease without additional cost and radiation exposure.

Edema progression in proximity to traumatic microbleeds: evolution of cytotoxic and vasogenic edema on serial MRI.

Introduction: Although cerebral edema is common following traumatic brain injury (TBI), its formation and progression are poorly understood. This is especially true for the mild TBI population, who rarely undergo magnetic resonance imaging (MRI) studies, which can pick up subtle structural details not visualized on computed tomography, in the first few days after injury. This study aimed to visually classify and quantitatively measure edema progression in relation to traumatic microbleeds (TMBs) in a cohort of primarily mild TBI patients up to 30 days after injury. Researchers hypothesized that hypointense lesions on Apparent Diffusion Coefficient (ADC) detected acutely after injury would evolve into hyperintense Fluid Attenuated Inversion Recover (FLAIR) lesions. Methods: This study analyzed the progression of cerebral edema after acute injury using multimodal MRI to classify TMBs as potential edema-related biomarkers. ADC and FLAIR MRI were utilized for edema classification at three different timepoints: ≤48 hours, ~1 week, and 30 days after injury. Hypointense lesions on ADC (ADC+) suggested the presence of cytotoxic edema while hyperintense lesions on FLAIR (FLAIR+) suggested vasogenic edema. Signal intensity Ratio (SIR) calculations were made using ADC and FLAIR to quantitatively confirm edema progression. Results: Our results indicated the presence of ADC+ lesions ≤48 hours and ~1 week were associated with FLAIR+ lesions at ~1 week and 30 days, respectively, suggesting some progression of cytotoxic edema to vasogenic edema over time. Ten out of 15 FLAIR+ lesions at 30 days (67%) were ADC+ ≤48 hours. However, ADC+ lesions ≤48 hours were not associated with FLAIR+ lesions at 30 days; 10 out of 25 (40%) ADC+ lesions ≤48 hours were FLAIR+ at 30 days, which could indicate that some lesions resolved or were not visualized due to associated atrophy or tissue necrosis. Quantitative analysis confirmed the visual progression of some TMB lesions from ADC+ to FLAIR+. FLAIR SIRs at ~1 week were significantly higher when lesions were ADC+ ≤48 hours (1.22 [1.08-1.32] vs 1.03 [0.97-1.11], p=0.002). Conclusion: Awareness of how cerebral edema can evolve in proximity to TMBs acutely after injury may facilitate identification and monitoring of patients with traumatic cerebrovascular injury and assist in development of novel therapeutic strategies.

Nucleocytoplasmic transport rates are regulated by cellular processes that modulate GTP availability.

Nucleocytoplasmic transport (NCT), the facilitated diffusion of cargo molecules between the nucleus and cytoplasm through nuclear pore complexes (NPCs), enables numerous fundamental eukaryotic cellular processes. Ran GTPase uses cellular energy in the direct form of GTP to create a gradient across the nuclear envelope (NE) that drives the majority of NCT. We report here that changes in GTP availability resulting from altered cellular physiology modulate the rate of NCT, as monitored using synthetic and natural cargo, and the dynamics of Ran itself. Cell migration, cell spreading, and/or modulation of the cytoskeleton or its connection to the nucleus alter GTP availability and thus rates of NCT, regulating RNA export and protein synthesis. These findings support a model in which changes in cellular physiology that alter GTP availability can regulate the rate of NCT, impacting fundamental cellular processes that extensively utilize NCT.

A Randomized Trial of Healthy Weight Gain in Athletic Individuals.

PURPOSE: The purpose of this study is to evaluate the outcomes of a 10-wk diet and exercise regimen designed to promote healthy weight gain with excess energy from peanut-containing or high-carbohydrate foods. METHODS: Nineteen male and 13 female athletes were randomly assigned to receive an additional 500 kcal·d -1 above typical intake through provision of either peanut-based whole foods/snacks (PNT group) or a similar, high-carbohydrate, peanut-free snack (CHO group) along with supervised, whole-body RT (3 d·wk -1 for 60-120 min). Body composition was assessed by dual-energyx-ray absorptiometry at baseline and postintervention. RESULTS: Total body mass (TBM) increased 2.2 ± 1.3 kg with 1.5 ± 1.1 kg as LBM after week 10. The PNT group ( n = 16; 27 ± 7 yr; 10 men, 6 women) gained less TBM than the CHO group ( n = 16; 23 ± 3 yr; 9 men, 7 women) (1.6 ± 1.1 kg vs 2.7 ± 1.2 kg, respectively, P = 0.007) with no differences in LBM (1.2 ± 1.1 kg vs 1.9 ± 1.0 kg, P = 0.136). CONCLUSIONS: These results suggest that the addition of 500 kcal·d -1 from whole foods/snacks in combination with a rigorous RT program promotes a similar weight gain of ~0.22 kg·wk -1 , primarily as LBM, over 10 wk in both male and female athletes. However, snack macronutrient content may impact the effectiveness of this regimen.

Effect of photobiomodulation therapy as a multimodal approach to treatment of dermal abrasions in cownose rays (Rhinoptera bonasus).

Photobiomodulation therapy (PBMT) has become increasingly utilized in the zoo and aquarium fields to treat ailments in various species; however, its use in teleosts and elasmobranchs is relatively underrepresented in the literature. This study examined the efficacy of PBMT as an adjunct treatment to reduce the healing time of dermal abrasions in cownose rays (Rhinoptera bonasus). Ten cownose rays were included in this study and separated into control (n = 5) and treatment groups (n = 5). Animals in both treatment and control groups received intramuscular injections of enrofloxacin every 72 h to provide broad-spectrum antibiotic coverage. Cownose rays in the treatment group additionally received PBMT using the Companion® CTC-12 unit using the large, noncontact head. Control group rays were subjected to identical handling without the use of PBMT. A total of 196 Joules were delivered at a power of 2 W based on a dose of 5 J/cm2 at each session. Observational analysis revealed a lack of appreciable difference in healing time between the treatment and control groups in the aforementioned settings; however, it is recommended that PBMT protocols should be re-evaluated if there is little to no response in healing after three to four sessions. PBMT use on acute superficial dermal abrasions in cownose rays was well-tolerated in this study and may have utility in a multimodal treatment approach to wound healing. This study also produced a wound scoring metric based on photographs captured at each treatment. Future studies should utilize increased fluence (J/cm2) and irradiance (W/cm2) and incorporate synchronous histological analysis and increased sample size.

Sickle cell disease iPSC-derived sensory neurons exhibit increased excitability and sensitization to patient plasma.

ABSTRACT: Individuals living with sickle cell disease (SCD) experience severe recurrent acute and chronic pain. Challenges to gaining mechanistic insight into pathogenic SCD pain processes include differential gene expression and function of sensory neurons between humans and mice with SCD, and extremely limited availability of neuronal tissues from patients with SCD. Here, we used induced pluripotent stem cells (iPSCs), derived from patients with SCD, differentiated into sensory neurons (SCD iSNs) to begin to overcome these challenges. We characterize key gene expression and function of SCD iSNs to establish a model to investigate intrinsic and extrinsic factors that may contribute to SCD pain. Despite similarities in receptor gene expression, SCD iSNs show pronounced excitability using patch clamp electrophysiology. Furthermore, we find that plasma taken from patients with SCD during acute pain associated with a vaso-occlusive event increases the calcium responses to the nociceptive stimulus capsaicin in SCD iSNs compared with those treated with paired plasma from patients with SCD at steady state baseline or healthy control plasma samples. We identified high levels of the polyamine spermine in baseline and acute pain states of plasma from patients with SCD, which sensitizes SCD iSNs to subthreshold concentrations of capsaicin. Together, these data identify potential intrinsic mechanisms within SCD iSNs that may extend beyond a blood-based pathology.

Contextual predictors of self-management and independence trajectories in adolescents and young adults with spina bifida.

AIM: To examine socioeconomic, condition-related, and neuropsychological predictors of self-management trajectories in adolescents and young adults with spina bifida. METHOD: In this longitudinal study, participants completed the Adolescent/Young Adult Self-Management and Independence Scale interview. Socioeconomic status (SES), shunt status, lesion level, and executive functioning were assessed. Growth in self-management was estimated using linear mixed-effects models. RESULTS: Participants (n = 99) were aged 18 to 27 years. Approximately half (52.5%) were female and White; 15.2% were Black; and 32.3% Hispanic or Latino. Although none of the predictors were associated with growth in self-management from ages 18 to 27 years (p > 0.05), several factors were associated with the intercept at age 18 years for total self-management. Higher SES at baseline predicted a higher total self-management score at age 18 years (b = 0.03, standard error [SE] = 0.01; p < 0.001). On average, participants at age 18 years with a shunt scored lower than those without a shunt (b = -0.90, SE = 0.32; p = 0.01); those with a thoracic lesion scored lower than those with lower lesion levels (lumbar: b = -1.22, SE = 0.34; sacral: b = -1.20, SE = 0.36; p = 0.001 for both). Better parent-reported and teacher-reported executive functions predicted higher total self-management (metacognitive: b = -0.03, SE = 0.01; behavioral regulation: b = -0.04, SE = 0.01; p < 0.05 for both). INTERPRETATION: On average, all participants improved in self-management over time. Additionally, baseline superiority in self-management for adolescents and young adults without a shunt, less severe lesions, better executive functions, and higher SES persisted over time.

REhabilitation Approaches in CHildren with cerebellar mutism syndrome (REACH): An international cross-disciplinary survey study.

OBJECTIVE: Pediatric cerebellar mutism syndrome (pCMS) can occur following resection of a posterior fossa tumor and, although some symptoms are transient, many result in long-lasting neurological deficits. A multi-disciplinary rehabilitation approach is often used in cases of pCMS; however, there have been no clinical trials to determine gold standards in rehabilitation practice in this population, which remains a research priority. The purpose of this study was to identify and compare intervention practices used in pCMS throughout the disciplines of occupational and physical therapy, speech-language pathology, and neuropsychology across geographic regions. METHODS: A 55-question e-survey was created by an international multidisciplinary research group made up of members of the Posterior Fossa Society and sent to rehabilitation professionals in pediatric neuro-oncology centers in the US, Canada, and Europe. RESULTS: Although some differences in the type of intervention used in pCMS were identified within each discipline, many of the targeted interventions including dose, frequency, and intensity were similar within disciplines across geographic regions. In addition, there were common themes identified across disciplines regarding challenges in the rehabilitation of this population. CONCLUSION: These results provide a foundation of current practices on which to build future intervention-based clinical trials.

Murine IRF8 Mutation Offers New Insight into Osteoclast and Root Resorption.

Interferon regulatory factor 8 (IRF8), a transcription factor expressed in immune cells, functions as a negative regulator of osteoclasts and helps maintain dental and skeletal homeostasis. Previously, we reported that a novel mutation in the IRF8 gene increases susceptibility to multiple idiopathic cervical root resorption (MICRR), a form of tooth root resorption mediated by increased osteoclast activity. The IRF8 G388S variant in the highly conserved C-terminal motif is predicted to alter the protein structure, likely impairing IRF8 function. To investigate the molecular basis of MICRR and IRF8 function in osteoclastogenesis, we generated Irf8 knock-in (KI) mice using CRISPR/Cas9 technique modeling the human IRF8G388S mutation. The heterozygous (Het) and homozygous (Homo) Irf8 KI mice showed no gross morphological defects, and the development of hematopoietic cells was unaffected and similar to wild-type (WT) mice. The Irf8 KI Het and Homo mice showed no difference in macrophage gene signatures important for antimicrobial defenses and inflammatory cytokine production. Consistent with the phenotype observed in MICRR patients, Irf8 KI Het and Homo mice demonstrated significantly increased osteoclast formation and resorption activity in vivo and in vitro when compared to WT mice. The oral ligature-inserted Het and Homo mice displayed significantly increased root resorption and osteoclast-mediated alveolar bone loss compared to WT mice. The increased osteoclastogenesis noted in KI mice is due to the inability of IRF8G388S mutation to inhibit NFATc1-dependent transcriptional activation and downstream osteoclast specific transcripts, as well as its impact on autophagy-related pathways of osteoclast differentiation. This translational study delineates the IRF8 domain important for osteoclast function and provides novel insights into the IRF8 mutation associated with MICRR. IRF8G388S mutation mainly affects osteoclastogenesis while sparing immune cell development and function. These insights extend beyond oral health and significantly advance our understanding of skeletal disorders mediated by increased osteoclast activity and IRF8's role in osteoclastogenesis.

Concussion diagnosis and recovery in relation to collegiate athletic department classification: a LIMBIC MATARS consortium investigation.

PURPOSE: We investigated time to reach concussion diagnosis and recovery milestones in collegiate athletes relative to their schools' National Collegiate Athletic Association (NCAA) classification. METHODS: We retrospectively examined 849 (43.1% female) concussion cases from 11 NCAA institutions (Division I Power 5 [n = 4], Division I Non-Power 5 [n = 4], and Division II/III [n = 3]) from the 2015-16 to 2019-20 athletic seasons. Our primary outcome measures were days to reach specific clinical milestones following concussion. RESULTS: Median (IQR) time from injury to diagnosis was significantly longer at Division II/III institutions (1 [0-4] days) compared to Division I Power 5 (0 [0-1] days) and Division I Non-Power 5 (0 [0-1] days) institutions (p < 0.001). Likewise, Division II/III athletes (15 [11-22] days) took significantly longer to return to sport after concussion than Division I Power 5 (10 [7-16] days) and Division I Non-Power 5 (11 [7-18.5] days) athletes (p < 0.001). CONCLUSION: Division II/III athletes had delayed concussion diagnoses and return to sport timelines compared to Division I athletes. Our results suggest that differences in sports medicine resources across NCAA divisions may influence injury recognition and recovery in collegiate athletes with concussion.

Emergency Department Access to Buprenorphine for Opioid Use Disorder.

Importance: Although substantial evidence supports buprenorphine for treatment of opioid use disorder (OUD) in controlled trials, prospective study of patient outcomes in clinical implementation of emergency department (ED) buprenorphine treatment is lacking. Objective: To examine the association between buprenorphine treatment in the ED and follow-up engagement in OUD treatment 1 month later. Design, Setting, and Participants: This multisite cohort study was conducted in 7 California EDs participating in a statewide implementation project to improve access to buprenorphine treatment. The study population included ED patients aged at least 18 years identified with OUD between April 1, 2021, and June 30, 2022. Data analysis was performed in October 2023. Exposure: All participants were offered buprenorphine treatment for OUD (either in ED administration, prescription, or both), the uptake of which was examined as the exposure of interest. Main Outcomes and Measures: The primary outcome was engagement in OUD treatment 30 days after the ED visit, determined by patient report or clinical documentation. The association of ED buprenorphine treatment with subsequent OUD treatment engagement was estimated using hierarchical generalized linear models. Results: This analysis included 464 ED patients with OUD. Their median age was 36.0 (IQR, 29.0-38.7) years, and most were men (343 [73.9%]). With regard to race and ethnicity, 64 patients (13.8%) self-identified as non-Hispanic Black, 183 (39.4%) as Hispanic, and 185 as non-Hispanic White (39.9%). Most patients (396 [85.3%]) had Medicaid insurance, and more than half (262 [57.8%]) had unstable housing. Self-reported fentanyl use (242 [52.2%]) and a comorbid mental health condition (328 [71.5%]) were common. Interest in buprenorphine treatment was high: 398 patients (85.8%) received buprenorphine treatment; 269 (58.0%) were administered buprenorphine in the ED and 339 (73.1%) were prescribed buprenorphine. With regard to OUD treatment engagement at 30 days after the ED visit, 198 participants (49.7%) who received ED buprenorphine treatment remained engaged compared with 15 participants (22.7%) who did not receive ED buprenorphine treatment. An association of ED buprenorphine treatment with subsequent OUD treatment engagement at 30 days was observed (adjusted risk ratio, 1.97 [95% CI, 1.27-3.07]). Conclusions and Relevance: The findings of this cohort study suggest that among patients with OUD presenting to EDs implementing low-threshold access to medications for OUD, buprenorphine treatment was associated with a substantially higher likelihood of follow-up treatment engagement 1 month later. Future research should investigate techniques to optimize both the uptake and effectiveness of buprenorphine initiation in low-threshold settings such as the ED.

Conditions that influence coping mechanisms in Latina mothers affected by incarceration: A secondary analysis using the vulnerability framework.

The objective of this study is to assess women's vulnerability to becoming involved with the legal system as it relates to their exposure, sensitivity, and resiliency to specific experiences associated with incarceration before, during, and after their confinement using the vulnerability framework. We sampled 12 women who self-identified as Latina mothers from local jail annexes, probation department offices, and substance use treatment centers in South Central Texas. We conducted a qualitative, secondary analysis. Three overarching themes emerged: (1) "[The abuse] just kept happening;" (2) "[Incarceration] was an excessive interference;" and (3) "I wasn't there back then [for my children], but now I can be [there for them] in some way." We also identified subthemes. More research and culturally tailored programming are needed to bridge services across legal system sites (jails, prisons, probation) that interact with this population of women to provide supportive services. PUBLIC CONTRIBUTION: We would like to recognize community stakeholders who work in the local jail, probation, and medication treatment centers who helped with the distribution of fliers and participant recruitment along with the women who shared their experiences following incarceration for the original study's data used in this secondary analysis.
