RESUMO

Rationale: Pulmonary ionocytes are a newly discovered airway epithelial cell type proposed to be a major contributor to cystic fibrosis (CF) lung disease based on observations they express the cystic fibrosis transmembrane conductance regulator (CFTR) anion channel at a higher level than any other cell type in the airway epithelia. Moreover, genetically manipulated experimental models that lack ionocytes develop NaCl transport abnormalities and airway surface liquid (ASL) dehydration consistent with CF. However, no direct evidence indicates ionocytes engage in NaCl transport or contribute to ASL formation, questioning the relevance of ionocytes to CF lung disease. Objectives: To determine the ion transport properties of pulmonary ionocytes and club cells in genetically intact healthy and CF airway epithelia. Methods: We measured ion transport at the single-cell level using a self-referencing ion-selective microelectrode technique in primary human bronchial epithelial cell culture. Measurements and Main Results: cAMP-stimulated non-CF ionocytes do not secrete Na+ or Cl- into the ASL, but rather modulate its pH by secreting bicarbonate via CFTR-linked Cl-/bicarbonate exchange. Non-CF club cells secrete Na+ and Cl- to the lumen side after cAMP stimulation. CF ionocytes and club cells do not transport ions in response to cAMP stimulation, but incubation with CFTR modulators elexacaftor/tezacaftor/ivacaftor restores transport properties. Conclusions: We conclude that ionocytes do not contribute to ASL formation but regulate ASL pH. Club cells secrete the bulk of airway fluid. In CF, abnormal ionocyte and club cell function results in acidic and dehydrated ASL, causing reduced antimicrobial properties and mucociliary clearance.

RESUMO

Leaf spongy mesophyll cells form an interconnected network of branched cells and intercellular spaces to maximize the surface area available for light capture and photosynthetic gas exchange. To investigate the morphogenetic events leading to cell separation and branching in Arabidopsis thaliana, we used mesophyll-specific promoters to facilitate imaging of mesophyll cell shape and microtubule (MT) organization over multiple spatiotemporal scales without interference from the overlying epidermal cells. We show that cells enlarge by selective expansion of cell wall regions in contact with intercellular spaces. Cell-cell contacts remain relatively fixed in size, forming the termini of interconnecting branches. Surprisingly, classic schizogeny (de-adhesion of neighboring cells) is relatively infrequent, being related to the local topology of cell junctions during early expansion. Intercellular spaces cue the position of stable MT bundles, which in turn promote efficient dilation of intercellular spaces and cell branching. Our data provide insights into mesophyll morphogenesis and MT organization and lay the groundwork for future investigations.

RESUMO

Cordyceps militaris is a well-known medicinal mushroom in Asian countries. This edible fungus has been widely exploited for traditional medicine and functional food production. C. militaris is a heterothallic fungus that requires both the mating-type loci, MAT1-1 and MAT1-2, for fruiting body formation. However, recent studies also indicated two groups of C. militaris, including monokaryotic strains carrying only MAT1-1 in their genomes and heterokaryotic strains harboring both MAT1-1 and MAT1-2. These strain groups are able to produce fruiting bodies under suitable cultivating conditions. In previous work, we showed that monokaryotic strains are more stable than heterokaryotic strains in fruiting body formation through successive culturing generations. In this study, we report a high cordycepin-producing monokaryotic C. militaris strain (HL8) collected in Vietnam. This strain could form normal fruiting bodies with high biological efficiency and contain a cordycepin content of 14.43 mg/g lyophilized fruiting body biomass. The ethanol extraction of the HL8 fruiting bodies resulted in a crude extract with a cordycepin content of 69.15 mg/g. Assays of cytotoxic activity on six human cancer cell lines showed that the extract inhibited the growth of all these cell lines with the IC50 values of 6.41-11.51 µg/mL. Notably, the extract significantly reduced cell proliferation and promoted apoptosis of breast cancer cells. Furthermore, the extract also exhibited strong antifungal activity against Malassezia skin yeasts and the citrus postharvest pathogen Penicillium digitatum. Our work provides a promising monokaryotic C. militaris strain as a bioresource for medicine, cosmetics, and fruit preservation.

RESUMO

OBJECTIVE: To examine the impact of the COVID-19 pandemic on cervical cancer screening rates of Hispanic individuals compared to non-Hispanic White (NHW) individuals in the United States, whether a responsive surge in catch-up screenings occurred as society adapted to pandemic changes, and to investigate the sociodemographic characteristics between the study populations. METHODS: Using cross-sectional data from the All of Us Research Program, which incorporates electronic health record data and survey data from a demographically, geographically, and medically diverse participant group, we assessed the annual cervical cancer screening rates during 2019-2021 by race/ethnicity among eligible individuals ages 21-64. RESULTS: Among 116,052 unique individuals (78,829 NHW and 37,223 Hispanic), Hispanic individuals had lower annual cervical cancer screening rates than NHWI across the three years studied. They experienced a more significant decrease in screening from 2019 to 2020 (39.27 %) compared to NHWIs (21.15 %) and less of a rebound increase in the following year, 2021 (10.33 % vs 13.83 %). Hispanic individuals aged 50-64 experienced the sharpest decline in screening rates (-43.01 % from 2019 to 2020). Hispanic individuals also experienced greater adverse social conditions, including lack of insurance or employment, lower educational attainment, and lower household income. CONCLUSIONS: Hispanic individuals experienced a more significant decrease in cervical cancer screening rates with the onset of the COVID-19 pandemic compared with NHW individuals and did not experience a robust rebound in cervical cancer screening rates in 2021. As a result, the disparity in cervical cancer screening rates between NHW and Hispanic individuals considerably worsened with the COVID-19 pandemic.

RESUMO

The degree of contamination of retail meat with colistin-resistant bacteria and its potential contribution to dissemination within communities remains to be determined. Thus, we aimed to elucidate the contamination status of colistin-resistance genes, indicative of colistin-resistant bacteria, in retail meats in Vietnam. In total, 46 chicken and 49 pork meats from stores in Vietnam and Japan were examined. Multiplex real-time polymerase chain reaction with TaqMan probes was performed for detecting mcr-1, mcr-3, and Escherichia coli 16S rRNA. Colistin-resistant bacteria in meats were isolated using selective media. The minimum inhibitory concentrations of colistin were determined using the broth microdilution method. The results showed that 70.7% of chicken meats in Vietnam were contaminated with both mcr-1 and mcr-3. Meanwhile, mcr-1 and mcr-3 were detected in 15.9% and 40.9% of pork meat, respectively. Only mcr-3 was detected in 40% of chicken in Japan. In addition, mcr-1-harboring E. coli and mcr-3-harboring Aeromonas were isolated from chicken meats in Vietnam. Some of these isolates showed colistin resistance. These results showed that most retail meats were highly contaminated with colistin-resistance genes. Notably, our results suggest that mcr-3 is more prevalent in the contaminated samples compared with mcr-1.

RESUMO

BACKGROUND: Smoking has long been recognized as a risk factor for impaired wound and bone healing, particularly in the context of ankle and foot surgery. Despite numerous studies exploring the association between smoking and complications following ankle replacement, there remains significant inconsistency in their findings. Therefore, this meta-analysis study aims to elucidate whether smoking increases the rate of complications after total ankle arthroplasty (TAA), providing valuable insights for clinical management. METHODS: A comprehensive systematic search was conducted in the PubMed, Embase, and Wiley databases to identify relevant English studies on the influence of smoking on postoperative complications following ankle replacement without any restrictions on publication dates. The quality of the included studies was assessed using the Newcastle-Ottawa Scale. Random-effect models were used to calculate odds ratios (OR) and 95 % confidence intervals (CI). This study adhered to PRISMA guidelines for transparent reporting and was registered with PROSPERO. RESULTS: The analysis incorporated data from 12 retrospective cohort studies, totaling 17331 subjects, 2580 of whom were smokers and 791 complications following TAA. The findings revealed a statistically significant disparity in wound-related complications (OR: 2.26; 95 % CI: 1.13-4.50; P = .02), particularly evident in current smokers with an OR of 3.30 (95 % CI: 2.12-5.14; P < .00001). However, we lacked sufficient evidence to substantiate an association between smoking and complications related to the prosthesis (OR: 1.09; 95 % CI: 0.77-1.53; P = .64) or systemic complications (OR: 1.18; 95 % CI: 0.10-14.13; P = .90) following TAA. CONCLUSIONS: Smoking, especially current smoking, is associated with increased wound complication risk post-operation for total ankle arthroplasty. Despite a lack of definitive evidence on the optimal timeframe for smoking cessation before surgery, discontinuing smoking appears to be a prudent measure to mitigate these complications.

RESUMO

Peripheral infection induces inflammation in peripheral tissues and the brain, impacting brain function. Glial cells are key players in this process. However, the effects of peripheral infection on glial activation and brain function remain unknown. Here, we showed that varying degrees of peripheral infection had different effects on the regulation of brain functions by microglia-dependent and -independent mechanisms. Acute mild infection (one-day LPS challenge: 1LPS) exacerbated middle cerebral artery occlusion (MCAO) injury, and severe infection (four-day LPS challenge: 4LPS) for one week suppressed it. MCAO injury was assessed by triphenyltetrazolium chloride staining. We observed early activation of microglia in the 1LPS and 4LPS groups. Depleting microglia with a colony-stimulating factor-1 receptor (CSF1R) antagonist had no effect on 1LPS-induced brain injury exacerbation but abolished 4LPS-induced protection, indicating microglial independence and dependence, respectively. Microglia-independent exacerbation caused by 1LPS involved peripheral immune cells including macrophages. RNA sequencing analysis of 4LPS-treated microglia revealed increased factors related to anti-inflammatory and neuronal tissue repair, suggesting their association with the protective effect. In conclusion, varying degrees of peripheral inflammation had contradictory effects (exacerbation vs. protection) on MCAO, which may be attributed to microglial dependence. Our findings highlight the significant impact of peripheral infection on brain function, particularly in relation to glial cells.

RESUMO

Breast cancer incidence among Asian Americans increased at a rate of 1.8% per year from 2014 to 2018, while the general population's incidence rate remained stable. Vietnamese-American women have been found to have the longest follow-up time after an abnormal mammogram. This study assesses the impact of a patient navigator program for Vietnamese-American women who received abnormal mammograms. Ninety-six Vietnamese-American participants with abnormal mammograms were assigned a Vietnamese patient navigator to provide emotional support, education, translation, and assistance with medical bills and doctor's appointments. Data collected from pre-test, post-test (1 year after initial enrollment in program), and 3-month follow-up surveys measured psychosocial outcomes and participant satisfaction. All 96 participants attended follow-up appointments for their abnormal mammograms. Psychosocial outcomes worsened from pre- to post-test, though these results were not statistically significant. Feeling in control of situations in one's life improved and was significant for participants who did not receive a breast cancer diagnosis (4.31, 5.04, p = .039). A majority of the participants reported satisfaction with their patient navigators. Vietnamese-American women have been found to be the least adherent to appropriate follow-up after an abnormal mammogram; in this study, all 96 participants attended a follow-up appointment within 90 days. Findings did not show improvements in psychosocial outcomes. Past research suggests that sociocultural factors may be at play: the initial abnormal mammogram may have triggered fatalistic thoughts affecting the reactions of the participants, even though the abnormal mammogram did not result in a breast cancer diagnosis.

RESUMO

BACKGROUND: Short meal-to-bed time (MTBT) has been reported to relate to gastroesophageal reflux disease (GERD), but evidence is lacking in pregnant women. We aimed to assess the characteristics of GERD and the association between MTBT and GERD during pregnancy. PATIENTS AND METHODS: A cross-sectional study was carried out on 400 pregnant women aged 18 years and older visiting the antenatal clinic of Gia-Dinh People's Hospital, Vietnam. GERD was defined as having troublesome heartburn and/or regurgitation at least once a week. Reflux-related insomnia was defined as having difficulties in initiating or maintaining sleep through the night. MTBT was defined as "short" if it was ≤2 hours in more than two thirds of days in a week. RESULTS: There were 154 (38.5%) patients with GERD and 20 (13.0%) patients with reflux-related insomnia. In multivariate analysis, there were 3 factors significantly associated with GERD: third trimester [odds ratio (OR)=1.66; 95% confidence interval (CI): 1.03-2.69], previous history of typical reflux symptoms (OR=9.05; 95% CI: 5.29-15.50), and short MTBT (OR=12.73; 95% CI: 2.92-55.45). The frequency of reflux symptoms progressively increased across subgroups of patients with no short MTBT, either daytime or nighttime short MTBT, and with both daytime and nighttime short MTBT. Nighttime MTBT was also a significant risk factor for reflux-related insomnia (OR=4.60; 95% CI: 1.64-12.92). CONCLUSIONS: We reported for the first time that short MTBT was a predominant risk factor of GERD in pregnancy. This dieting habit was significantly associated with reflux symptom frequency and reflux-related insomnia.

RESUMO

BACKGROUND: The Institute of Medicine reported that more than 1.5 million preventable adverse drug events occur annually in the United States. Comprehensive Medication Management (CMM) is the medication review process to improve clinical outcomes, enhance patient adherence, reduce drug therapy problems and reduce health care costs. University of Texas (UT) Physicians implemented a CMM program in several community-based clinics. We evaluated the effectiveness of CMM to reduce drug therapy problems and achieve medical cost savings. METHODS: This was a retrospective, observational study of CMM participants from October 2015 to September 2016. Program participants included patients aged 18 years or older who had taken more than 4 prescribed medications and were diagnosed with at least one of the following chronic diseases: hypertension, congestive heart failure, chronic obstructive pulmonary disease, asthma or diabetes. Under the CMM program, a clinical pharmacist reviewed patients' electronic health records and created action plans to resolve identified drug problems. As part of the evaluation of the clinical process, two independent physicians conducted peer review on the recommendations issued by the pharmacist in order to establish inter-rater reliability of drug therapy problems and potential consequent medical services. The drug therapy problems were identified and classified into four categories: indication, effectiveness, safety and/or compliance. The average cost of avoided medical services was obtained based on cost extrapolations from the literature, combined with hospital discharge data. Potential medical services avoided were linked to the average cost of those services to calculate the total cost savings of the program from the payers' perspective. RESULTS: By reviewing electronic health records of 3280 patients, the pharmacist identified 301 drug therapy problems and resolved 49.8% of these problems with collaboration from the patient's primary care physician or care team. The most commonly identified drug problems were related to potentially adverse drug reactions or inappropriate drug dosage. The CMM program resulted in potential cost savings of $1,143,015. CONCLUSIONS: The CMM program resolved medication therapy problems among program participants and achieved significant health care cost savings.

RESUMO

This study examined the postoperative pain management practices among registered nurses in an urban hospital in Vietnam. Data of 90 nurses about postoperative pain management practices and pain management at the department were collected. Results indicated that 83.3% of nurses reported that they regularly assessed the degree of pain for postoperative patients. Only 32.2% used assessment tools such as the numeric rating scale to measure pain. Experience in pain management and having guidelines in the department were associated with a higher score in pain management practice. Findings suggested that facilitating the use of pain instruments and developing pain management guidelines should be prioritized.

RESUMO

Vietnamese nail salon workers have low cancer screening rates and confront multiple socioeconomic disparities as immigrants to the US. The Suc Khoe là Hanh Phúc (Vietnamese for "Health is Happiness") program was adapted to the cultural and work needs of this population and implemented at nail salons to increase cancer screening adherence. A total of 186 study participants were recruited from 59 nail salons in a neighborhood with mostly Asian population. After being pretested, workers were enrolled in a cancer education session delivered by Vietnamese lay health workers. Non-adherent cases were offered navigation to cancer screening services to a local federally qualified health center. Participants completed a posttest survey five months, on average. At posttest, navigated non-adherent participants were more likely to report a recent Pap test compared to cases not navigated (83.8% vs. 50.0%), an effect not observed for mammography uptake (77.3% vs. 71.4%). Time in the US, marital status, insurance status, having a primary care provider and/or a gynecologist were significantly associated with cancer screening adherence. Low rates of adherence to cancer screening among Vietnamese nail salons workers can be improved by community based programs addressing cultural and work-related barriers confronted by this population.

RESUMO

Treatment readiness is a key predictor of drug treatment completion, rearrest, and recidivism during community reentry; however, limited data exists among homeless, female ex-offenders (HFOs). The purpose of this study was to present baseline data from a randomized controlled trial of 130 HFOs who had been released from jail or prison. Over half (60.8%) of HFOs had a treatment readiness score of ≥ 40 (n = 79, µ = 40.2, SD = 8.72). Bivariate analyses revealed that methamphetamine use, psychological well-being, and high emotional support were positively associated with treatment readiness. On the other hand, depressive symptomology and depression/anxiety scores were negatively associated with the treatment readiness score. Multiple linear regression revealed that depressive symptomology was negatively associated with treatment readiness (ß = -0.377; p = .001). Further analyses revealed that the effect of emotional support on treatment readiness was mediated by depressive symptomatology.

RESUMO

OBJECTIVES: The objective of this study was to determine the prevalence and correlates of pretreatment drug resistance (PDR) to first-line antiretroviral drugs among people initiating therapy for HIV in Vietnam. METHODS: Blood was collected during November 2009 to October 2010 from people consecutively initiating ART in four purposively selected public outpatient clinics in three Vietnamese cities. At each study site, recruitment lasted for 6-10 months until the target sample size (range 120-130 individuals) had been reached. The viral load was measured in 501 samples; 490 samples (viral load ≥1000 copies/mL) were genotyped using a nucleotide population-based sequencing assay. Self-reported demographic and clinical data were elicited through interviews. We classified drug-resistance-associated mutations (DRMs) according to the 2009 WHO surveillance list. RESULTS: DRMs were identified in 17/490 participants (3.5%; 95% CI 2.2%-5.5%). The prevalence of DRMs was 1.6% (8/490) against NRTIs, 1.6% (8/490) against NNRTIs and 0.8% (4/490) against PIs; three (0.6%) participants were resistant to both NRTIs and NNRTIs. The overall prevalence of PDR to first-line drugs was low [2.7% (13/490); 95% CI 1.6%-4.4%]. The prevalence of PDR to first-line drugs was greater among 198 HIV-infected participants who injected drugs than among 286 participants who reported risks for sexually acquired HIV (4.0% versus 1.4%, P = 0.079). Multivariable logistic regression analysis suggested that PDR to first-line drugs was significantly higher among people who injected drugs (OR = 3.94; 95% CI 1.13-13.68). CONCLUSIONS: With low PDR, first-line ART may be effective in Vietnam and pretreatment genotyping may be unnecessary. Continuing strategies for the prevention and surveillance of antiretroviral resistance are important for maintaining a low prevalence of antiretroviral resistance in Vietnam. The association between resistance and injection drug use warrants further research.

RESUMO

OBJECTIVE: Few decision aids emphasize active surveillance (AS) for localized prostate cancer. Concept mapping was used to produce a conceptual framework incorporating AS and treatment. METHODS: Fifty-four statements about what men need to make a decision for localized prostate cancer were derived from focus groups with African American, Latino and white men previously screened for prostate cancer and partners (n = 80). In the second phase, 89 participants sorted and rated the importance of statements. RESULTS: An eight cluster map was produced for the overall sample. Clusters were labelled Doctor-patient exchange, Big picture comparisons, Weighing the options, Seeking and using information, Spirituality and inner strength, Related to active treatment, Side-effects and Family concerns. A major division was between medical and home-based clusters. Ethnic groups and genders had similar sorting, but some variation in importance. Latinos rated Big picture comparisons as less important. African Americans saw Spirituality and inner strength most important, followed by Latinos, then whites. Ethnic- and gender-specific concept maps were not analysed because of high similarity in their sorting patterns. CONCLUSIONS: We identified a conceptual framework for management of early-stage prostate cancer that included coverage of AS. Eliciting the conceptual framework is an important step in constructing decision aids which will address gaps related to AS.

RESUMO

Active surveillance is increasingly recognized as a reasonable option for men with low-risk, localized prostate cancer, yet few men who might benefit from conservative management receive it. The authors examined the acceptability of normative messages about active surveillance as a management option for patients with low-risk prostate cancer. Men with a diagnosis of localized prostate cancer who were recruited through prostate cancer support organizations completed a web-based survey (N = 331). They rated messages about active surveillance for believability, accuracy, and importance for men to hear when making treatment decisions. The message "You don't have to panic … you have time to think about your options" was perceived as believable, accurate, and important by more than 80% of the survivors. In contrast, messages about trust in the active surveillance protocol and "knowing in plenty of time" if treatment is needed were rated as accurate by only about 36% of respondents. For active surveillance to be viewed as a reasonable alternative, men will need reassurance that following an active surveillance protocol is likely to allow time for curative treatment if the cancer progresses.

RESUMO

BACKGROUND: Growing recognition that active surveillance (AS) is a reasonable management option for many men diagnosed with localized prostate cancer led us to describe patients' conceptualizations of AS and reasons for their treatment decisions. METHODS: Men were patients of a multidisciplinary prostate cancer clinic at a large tertiary cancer center where patients are routinely briefed on treatment options, including AS. We conducted a thematic analysis of interviews with 15 men who had chosen AS and 15 men who received radiation or surgery. RESULTS: Men who chose AS described it as an organized process with a rigorous and reassuring protocol of periodic testing, with potential for subsequent and timely decision-making about treatment. AS was seen as prolonging their current good health and function with treatment still possible later. Rationales for choosing AS included trusting their physician's monitoring, 'buying time' without experiencing adverse effects of treatment, waiting for better treatments, and seeing their cancer as very low risk. Men recognized the need to justify their choice to others because it seemed contrary to the impulse to immediately treat cancer. Descriptions of AS by men who chose surgery or radiation were less specific about the testing regimen. Getting rid of the cancer and having a cure were paramount for them. CONCLUSIONS: Men fully informed of their treatment options for localized prostate cancer have a comprehensive understanding of the purpose of AS. Slowing the decision-making process may enhance the acceptability of AS.

RESUMO

INTRODUCTION: The incidence of human papillomavirus (HPV) infection and cervical cancer can be reduced by increasing vaccination for HPV. Yet vaccination uptake and completion of the 3-dose series remain low among Puerto Rican females. This study explored psychosocial factors associated with HPV vaccination uptake decisions among Puerto Rican mothers and daughters. METHODS: We conducted 7 focus groups with young women aged 16 to 24 (n = 21) and their mothers (n = 9) to assess knowledge, attitudes, and beliefs related to cervical cancer, HPV, and HPV vaccination. We analyzed the focus group transcripts and identified themes by using a constant comparison method of qualitative data analysis and interpretation, guided by a grounded theory approach. RESULTS: The analysis identified several emergent themes related to vaccine uptake: 1) low knowledge about cervical cancer, HPV, and the HPV vaccine; 2) inconsistent beliefs about susceptibility to HPV infection and cervical cancer; 3) vaccine effectiveness; 4) vaccine safety and side effects; 5) concerns that the vaccine promotes sexual disinhibition; and 6) availability of insurance coverage and overall cost of the vaccine. CONCLUSION: Our study found that adolescent girls and young women in Puerto Rico have low levels of knowledge about HPV and cervical cancer, low perceived susceptibility to HPV, and concerns about the safety and efficacy of the vaccine, and these factors may influence uptake and completion of HPV vaccination. Interventions are needed for both mothers and daughters that address these psychosocial factors and increase access to vaccination.

RESUMO

Objectives: Cervical cancer has markedly declined due to widespread use of screening, but Hispanic women continue to bear a disproportionate amount of the cervical cancer burden due to under-screening. Previous studies have explored barriers to screening but have failed to identify targetable facilitators in this group. We aimed to assess facilitators to cervical cancer screening among a predominantly urban, Hispanic population who presented to a no-cost, community-based clinic. Methods: Patients completed demographic and health information, a validated social determinants of health (SDOH) screen, and a self-reported facilitators survey on factors which enabled them to present to clinic. Descriptive statistics were conducted to assess patients' sociodemographic characteristics, SDOH, and perceived facilitators. Results: 124 patients were included. 98 % were Hispanic, 90 % identified Spanish as their preferred language, and 94 % had no insurance. Median age was 41. 31 % of patients reported a history of abnormal screening. On SDOH, over 80 % of patients screened positive in at least one domain, with the most common being food insecurity (53 %) and stress (46 %). The most frequently reported facilitator was encouragement from a family member/friend (30 %). 26 % of patients reported time off from work and 25 % reported availability of child/elder care as facilitators. Conclusions: Identifying facilitators among patients who present for cervical cancer screening is critical to designing care plans to reach all populations. Our survey showed that the single greatest facilitator to patients presenting for cervical cancer screening was encouragement from a family member/friend. These findings suggest that increasing community involvement and awareness may help to improve cervical cancer screening in a minority, urban, underserved population.

RESUMO

OBJECTIVE: Social determinants of health (SDOH) significantly affect individuals' health outcomes, yet universal electronic SDOH screening is not standard in primary care. Our study explores the implementation of an electronic SDOH screening in the electronic health record (EHR) and follow-up intervention among primary care pediatric patients within an academic clinic. METHODS: Beginning in August of 2022, patients and their families determined to have at least one SDOH need qualified for an in-clinic referral to a coordinated care team member. We assessed the overall efficacy and feasibility of the implementation. RESULTS: Over the 4-month pilot, 1473 of 2064 (71.4%) eligible patients were screened, with 472 (32%) patients screening positive on at least one SDOH domain. Of the 472 screened positive, 48 (10.2%) declined a referral. Two hundred and forty-seven of the 424 (58.3%) received a referral to a care coordination team member. CONCLUSIONS: This study demonstrates the feasibility of a universal electronic SDOH screening tool within the EHR within an urban, academic-based clinic.
