OBJECTIVE: This study aimed to assess patients interest in education content delivered through electronic modalities and identify trends in internet access and use among emergency department patients of various socioeconomic statuses. METHODS: A prospective, cross-sectional survey with 50 questions was completed by 241 English and Spanish-speaking patients in 2014 and repeated with 253 participants in 2019 at the University of California, Irvine Medical Centers Emergency Department (UCIMCED). RESULTS: Internet access increased from 83.8 % in 2014 to 88.1 % in 2019. Most internet-using patients owned smartphones (80.1 % in 2014, 89.7 % in 2019). Patients used electronic devices, such as fit bits and activity trackers, to obtain health information. Email was the preferred method for receiving discharge instructions. CONCLUSIONS: As of 2019, 88.1 % of UCIMCED patients have access to the internet or email, making electronic media a reasonable venue for patient education. Given that we have a predominantly low-income patient population-61 % and 32 % of respondents in 2014 and 2019, respectively, reporting an income of less than $25,000-these results are provide new avenues to reach patients of all socioeconomic statuses. INNOVATION: The implications of this study can be used to develop electronic resources tailored to educate emergency department patients about their healthcare beyond the confines of a hospital.

OBJECTIVES: In the United States, pediatric emergency department (ED) visits for behavioral health (BH) are increasing. We sought to determine ED-level characteristics associated with having recommended BH-related policies. METHODS: We conducted a retrospective serial cross-sectional study of National Pediatric Readiness Project assessments administered to US EDs in 2013 and 2021. Changes in responses related to BH items over time were examined. Multivariable logistic regression models examined ED characteristics associated with the presence of specific BH-related policies in 2021. RESULTS: Of 3554 EDs that completed assessments in 2021, 73.0% had BH-related policies, 66.5% had transfer guidelines for children with BH issues, and 38.6% had access to BH resources in a disaster. Of 2570 EDs that completed assessments in both 2013 and 2021, presence of specific BH-related policies increased from 48.6% to 72.0% and presence of appropriate transfer guidelines increased from 56.2% to 64.9%. The adjusted odd ratios (aORs) of having specific BH-related policies were lower in rural (aOR 0.73; 95% confidence interval [CI] 0.57, 0.92) and remote EDs (aOR 0.65; 95% CI 0.48, 0.88) compared to urban EDs; lower among EDs with versus without trauma center designation (aOR 0.80; 95% CI 0.67, 0.95); and higher among EDs with a nurse and physician pediatric emergency care coordinator (PECC) (aOR 1.89; 95% CI 1.54, 2.33) versus those without a PECC. CONCLUSION: Although pediatric readiness for BH conditions increased from 2013 to 2021, gaps remain, particularly among rural EDs and designated trauma centers. Having nurse and physician PECCs is a modifiable strategy to increase ED pediatric readiness pertaining to BH.

ABSTRACT: Background: In Fall 2020, at the height of the COVID-19 pandemic, the importance of avoiding a simultaneous influenza and COVID-19 “twindemic” led to the implementation of socially distanced, drive-through mobile vaccination clinics. Mobile clinics have been valuable in providing primary and preventative care to underserved populations and expanding healthcare access to individuals marginalized by geographic, social, and structural barriers. Although there are ~2,000 mobile clinics throughout the United States and 120 mobile clinics providing services in California, few studies to date have evaluated neighborhood-level factors to determine whether social drivers of health (SDOH) influence the use of mobile drive-through clinics versus static clinics for immunizations. Methods: We conducted a retrospective cohort study of a total of 25,246 patients, 3,151 of whom received immunizations in 3 mobile clinics and 22,095 of whom received immunizations in 3 static clinics in Orange County from 8/1/2020 to 12/31/2020. Data were collected from patient charts on demographic characteristics. Age was stratified 0-21 years, 22-64 years, and 65 years and older. SDOH was measured using state-ranked Area Deprivation Index (ADI), a composite measure of 17 variables across income, education, employment, and housing domains by neighborhood/block group. ADI ranking was categorized into quintiles with higher ADI indices corresponding to greater levels of disadvantage. Chi-squared analysis was paired with logistic regression to examine potential associations. Significance was set at p < 0.05. Statistical analysis was conducted using SPSS (version 28) The study was approved by our institution’s IRB. Results: A similar percentage of patients who identified as White attended the mobile and static clinics (60.3% and 66.8%, respectively), while a lesser percentage of patients who were <60 years of age (60.3% vs 74.4%); identified as Hispanic (19.4% vs 58.8%); spoke Spanish (5.6% vs 33.7%); and were on public insurance (36.7% vs 74.9%) attended the mobile (vs static) clinics. Less likely to obtain vaccines through mobile clinics were those who identified as Black (OR 0.51; 95% CI 0.35, 0.75) relative to Caucasian patients, had public insurance (0.25; 0.23, 0.28) versus commercial insurance, and whose primary language was Spanish (0.29; 0.24, 0.35). Those greater than 65 years of age (7.04; 5.94, 8.34) compared to those under 21 years, and those identified as non-Hispanic (1.67; 1.44, 1.90) versus Hispanic were more likely to obtain their vaccines through the mobile clinic. Additionally, those who lived in the most disadvantaged neighborhoods were the least likely to obtain vaccines at the mobile clinic (0.67; 0.48, 0.93). Conclusions: The study demonstrates that patients who lived in more disadvantaged neighborhoods were less likely to seek vaccinations at mobile clinics. Additional work is needed to identify why the mobile influenza clinics were highly skewed towards those who lived in more advantaged areas.

Advancements in artificial intelligence (AI) for point-of-care ultrasound (POCUS) have ushered in new possibilities for medical diagnostics in low-resource settings. This review explores the current landscape of AI applications in POCUS across these environments, analyzing studies sourced from three databases-SCOPUS, PUBMED, and Google Scholars. Initially, 1196 records were identified, of which 1167 articles were excluded after a two-stage screening, leaving 29 unique studies for review. The majority of studies focused on deep learning algorithms to facilitate POCUS operations and interpretation in resource-constrained settings. Various types of low-resource settings were targeted, with a significant emphasis on low- and middle-income countries (LMICs), rural/remote areas, and emergency contexts. Notable limitations identified include challenges in generalizability, dataset availability, regional disparities in research, patient compliance, and ethical considerations. Additionally, the lack of standardization in POCUS devices, protocols, and algorithms emerged as a significant barrier to AI implementation. The diversity of POCUS AI applications in different domains (e.g., lung, hip, heart, etc.) illustrates the challenges of having to tailor to the specific needs of each application. By separating out the analysis by application area, researchers will better understand the distinct impacts and limitations of AI, aligning research and development efforts with the unique characteristics of each clinical condition. Despite these challenges, POCUS AI systems show promise in bridging gaps in healthcare delivery by aiding clinicians in low-resource settings. Future research endeavors should prioritize addressing the gaps identified in this review to enhance the feasibility and effectiveness of POCUS AI applications to improve healthcare outcomes in resource-constrained environments.

We previously demonstrated that a genetic single-nucleotide polymorphism (SNP, rs2304297) in the 3 untranslated region (UTR) of the human CHRNA6 gene has sex- and genotype-dependent effects on nicotine-induced locomotion, anxiety, and nicotine + cue-induced reinstatement in adolescent rats. This study aims to investigate how the CHRNA6 3-UTR SNP influences dopaminergic and noradrenergic tissue levels in brain reward regions during baseline and after the reinstatement of drug-seeking behavior. Naïve adolescent and adult rats, along with those undergoing nicotine + cue reinstatement and carrying the CHRNA6 3-UTR SNP, were assessed for dopamine (DA), norepinephrine (NE), and metabolites in reward pathway regions. The results reveal age-, sex-, and genotype-dependent baseline DA, NE, and DA turnover levels. Post-reinstatement, male α6GG rats show suppressed DA levels in the Nucleus Accumbens (NAc) Shell compared to the baseline, while nicotine+ cue-induced reinstatement behavior correlates with neurotransmitter levels in specific brain regions. This study emphasizes the role of CHRNA6 3-UTR SNP in the developmental maturation of the dopaminergic and noradrenergic system in the adolescent rat brain, with tissue levels acting as predictors of nicotine + cue-induced reinstatement.

In healthcare professions, soft skills contribute to critical thinking, decision-making, and patient-centered care. While important to the delivery of high-quality medical care, soft skills are often underemphasized during healthcare training in low-and-middle-income countries. Despite South Asias large population, the efficacy and viability of a digital soft skills curriculum for South Asian healthcare practitioners has not been studied to date. We hypothesized that a web-based, multilingual, soft skills course could aid the understanding and application of soft skills to improve healthcare practitioner knowledge, confidence, attitudes, and intent-to-change clinical practice.In September 2019 a needs assessment observing soft skills practices was conducted in several Indian states. We developed a communication-focused soft skills curriculum that comprised seven 10-minute video lectures, recorded in spoken English and Hindi. Participants consisted of any practicing healthcare professionals and trainees in select South Asian countries age 18 and over. Participant knowledge, confidence, attitudes, and intent-to-change clinical practice were evaluated using pre- and post-course tests and surveys. Statistical analyses were performed using STATA and SPSS.From July 26, 2021 to September 26, 2021, 5750 registered and attempted the course, 2628 unique participants completed the pre-test, and 1566 unique participants completed the post-test. Participants demonstrated small but statistically significant gains in confidence (𝑝<0.001), attitudes toward course topics relevance (𝑝<0.001), and intent-to-change clinical practice (𝑝<0.001). There was no statistically significant gain in knowledge. A digital soft-skills massive open online course for healthcare practitioners in South Asia could serve as a viable approach to improve the quality of soft skills training in low-to-middle income countries.

BACKGROUND: The prevalence and burden of substance and opium use have increased worldwide over the past decades. In light of rapid population changes in Tehran, we aimed to evaluate the prevalence of opium and other substance use among adult residents in Tehran, Iran. METHOD: From March 2016 to March 2019, we utilized data from 8 296 participants in the Tehran Cohort Study recruitment phase (TeCS). We calculated the age-sex-weighted prevalence of substance use and the geographic distribution of substance use in Tehran. We also used logistic regression analysis to determine possible determinants of opium use. RESULT: We analyzed data from 8 259 eligible participants with complete substance use data and the average age of participants was 53.7 ± 12.75 years. The prevalence of substance use was 5.6% (95% confidence interval [CI]: 4.6- 7.1%). Substance use was more common in males than females (Prevalence: 10.5% [95% CI: 8.6- 12.6%] vs. 0.5% [95% CI: 0.2- 1.2%], respectively). The age-sex weighted prevalence of substance use was 5.4% (95% CI: 4.6-7.1%). Moreover, opium was the most frequently used substance by 95.8% of substance users. Additionally, we found that male gender (Odds ratio [OR]: 12.1, P < 0.001), alcohol intake (OR: 1.3, P = 0.016), and smoking (OR: 8.5, P < 0.001) were independently associated with opium use. CONCLUSIONS: We found that the prevalence of substance use in Tehran was 5.6%, and opium was the most frequently used substance. In addition, male gender, lower levels of education, alcohol, and tobacco consumption are the main risk factors for substance use in Tehran. Healthcare providers and policymakers can utilize our results to implement preventive strategies to minimize substance use in Tehran.

BACKGROUND: Dyslipidemia is among the leading risk factors for cardiovascular diseases (CVDs), with an increasing global burden, especially in developing countries. We investigated the prevalence of dyslipidemia and abnormal lipid profiles in Tehran. METHODS: We used data from 8072 individuals aged≥35 from the Tehran Cohort Study (TeCS) recruitment phase. Fasting serum total cholesterol (TC), low-density lipoprotein-cholesterol (LDL-C), high-density lipoprotein-cholesterol (HDL-C), and triglyceride were measured. Dyslipidemia was defined according to the National Cholesterol Education Program Adult Treatment Panel III criteria, and high LDL/HDL was defined as a ratio>2.5. The age-sex standardized prevalence rates were calculated based on the 2016 national census. Furthermore, the geographical distribution of dyslipidemia and lipid abnormalities was investigated across Tehrans zip code districts. RESULTS: The age-sex standardized prevalence was 82.7% (95% CI: 80.1%, 85.0%) for dyslipidemia, 36.9% (95% CI: 33.8%, 40.1%) for hypertriglyceridemia, 22.5% (95% CI: 19.9%, 25.4%) for hypercholesterolemia, 29.0% (95% CI: 26.1%, 32.1%) for high LDL-C, 55.9% (95% CI: 52.6%, 59.2%) for low HDL-C, and 54.1% (95% CI: 50.9%, 57.3%) for high LDL/HDL ratio in the Tehran adult population. The prevalence of dyslipidemia, low HDL-C, and high LDL/HDL ratio was higher in the northern regions, hypercholesterolemia was higher in the southern half, and high LDL-C was more prevalent in the middle-northern and southern areas of Tehran. CONCLUSION: We found a high prevalence of dyslipidemia, mainly high LDL/HDL in the Tehran adult population. This dyslipidemia profiling provides important information for public health policy to improve preventive interventions and reduce dyslipidemiarelated morbidity and mortality in the future.

Community college (CC) has traditionally existed as a bridge between high school and a four-year, baccalaureate-awarding, university. With the ever-increasing number of CCs present in the United States and the rising numbers of applicants to medical school, there will inevitably be a substantial proportion of future physicians who have attended CC. Based on previous research, we surveyed the University of California, Irvine, School of Medicine (UCISOM) student body to assess how many students had attended CC, when and why they attended, and if they intended to practice with underserved communities in the future. A total of 30 (28.6%) of the 105 survey respondents attended CC prior to medical school. Those students cited Academic Flexibility, Financial Reasons/Affordability, and the inability to enroll in a particular course at their four-year institutions as the top three reasons for attending CC. Ten of those students (30%) reported they were informed that attending CC would negatively impact their medical school application. Older students were more likely to attend CC, and there was no statistically significant correlation between CC attendance and the number of times one applied to medical school or between CC attendance and gender, race, ethnicity, and intention to practice in underserved communities. This article highlights the understanding of the effects of CC attendance on medical school admissions while comparing our sample of 105 UCISOM students to previous research studies.
