Abstract Background The Affordable Care Act (ACA) has improved healthcare access in the community health centers that have played a critical role in enrolling low income and minority patients. This study examined the ACA enrollment for one of the largest federally qualified community health centers in the country. Methods An exploratory sequential mixed method study was used as the main qualitative and quantitative approach for this study. Key stakeholders (n = 6) were interviewed as part of the qualitative component, and information about barriers and best practices were acquired. As part of the quantitative analysis, we examined cross-sectional data among 59,272 AltaMed enrollees in 2013–2015. We analyzed data on age, gender, language, ethnicity, and enrollment periods. The interviews were conducted first and followed by the data analysis. Results AltaMed was the top enroller of patients in ACA insurance plans in California (2013–14 and 2014–15) through the state exchange and Medicaid expansion. Using key stakeholder interviews, 5 main barriers were identified and 5 innovative solutions that allowed AltaMed to enroll people into the state exchange and Medicaid expansion. Barriers to enrollment included training, new workflows, and enrollment of Young Invincibles, and these enrollment barriers were overcome with community health workers. Conclusion Enrollment barriers were overcome through AltaMed’s community-based approach and long term community partnerships.

Background Despite the risks of immunosuppression, recommendations regarding screening for HIV infection prior to initiation of biologic therapies targeting common rheumatologic disorders, including inflammatory bowel disease (IBD) and inflammatory arthritides, are limited. Few cases of patients started on biologics while living with undiagnosed HIV infection have been reported. Methods We report three cases of patients initiated on biologics in the absence of recent or concurrent HIV screening who developed refractory disease or unanticipated complications and were later found to have undiagnosed chronic HIV infection. Results In Case 1, a 53-year-old MSM with negative HIV testing 2 years prior presented with presumed rheumatoid arthritis. He did not respond to methotrexate, so adalimumab was started. HIV testing to evaluate persistent symptoms was positive 9 months later; CD4+ T-cell count was 800 cells/μl. Antiretroviral therapy (ART) resulted in resolution of symptoms, which were attributed to HIV-associated arthropathy. In Case 2, a 55-year-old woman with injection drug use in remission and no prior HIV testing presented with hidradenitis suppurativa. She started infliximab and methotrexate therapy with good response. After she developed weight loss and lymphopenia, an HIV test was positive; CD4+ T-cell count was 334 cells/μl. Biologic hidradenitis suppurativa therapy was discontinued, with subsequent poor hidradenitis suppurativa control. In Case 3, a 32-year-old MSM with no prior HIV testing presented with presumed IBD; infliximab and steroids were started. Symptoms progressed despite IBD-directed therapy, and he was diagnosed with extensive Kaposi sarcoma with visceral and cutaneous involvement, likely exacerbated by immunosuppression. HIV testing was positive; CD4+ T-cell count was 250 cells/μl. Kaposi sarcoma initially worsened due to ART-associated immune reconstitution inflammatory syndrome. He is now improving with systemic chemotherapy and ART. HIV-associated Kaposi sarcoma is presumed to be the underlying diagnosis. Conclusion All three patients had elevated risk for HIV infection, and two had final diagnoses attributed to chronic HIV infection, not warranting therapeutic immunosuppression. Screening for HIV infection prior to initiation of biologic therapy should be incorporated into clinical practice guidelines.

Author(s): Sorensen, Andrea; Grotts, Jonathan F; Tseng, Chi-Hong; Moreno, Gerardo; Maranon, Richard; Whitmire, Natalie; Viramontes, Omar; Atkins, Sandy; Sefilyan, Ester; Simmons, June W; Mangione, Carol M | Abstract: Background/objectivesMedication discrepancies and adverse drug events are common following hospital discharge. This study evaluates whether a collaboration between community-based health coaches and primary care-based pharmacists was associated with a reduction in inpatient utilization following hospitalization.DesignRetrospective cohort study using propensity score matching.SettingUrban academic medical center and surrounding community.ParticipantsIntervention patients (n = 494) were adults aged 65 and older admitted to the University of California, Los Angeles (UCLA) Ronald Reagan Medical Center during the study period and who met study inclusion criteria. A matched-control group was composed of patients with similar demographic and clinical characteristics who were admitted to the study site during the study period but who received usual care (n = 2,470). A greedy algorithm approach was used to conduct the propensity score match.InterventionFollowing acute hospitalization, a health coach conducted a home visit and transmitted all medication-related information to a pharmacist based in a primary care practice. The pharmacist compared this information with the patient's electronic medical record medication list and consulted with the patient's primary care provider to optimize medication management.MeasurementsThirty-day readmissions (primary outcome), 60- and 90-day readmissions, and 30-day emergency department (ED) visits (secondary outcomes) to UCLA Health.ResultsAmong 494 patients who received the intervention, 307 (62.1%) were female with a mean age of 83.0 years (interquartile range [IQR] = 76-90 years). Among 2,470 matched-control patients, 1,541 (62.4%) were female with a mean age of 82.7 years (IQR = 74.9-89.5 years). For the propensity score match, standardized mean differences were below .1 for 23 of 25 variables, indicating good balance. Patients who received this intervention had a significantly lower predicted probability of being readmitted within 30 days compared with matched-control patients (10.6%; 95% confidence interval [CI] = 7.9-13.2) vs 21.4%; 95% CI = 19.8-23.0; P value l .001).ConclusionA home visit conducted by a health coach combined with a medication review by a primary care-based pharmacist may prevent subsequent inpatient utilization.

The termination of the Deferred Action for Childhood Arrivals (DACA) immigration policy poses unique challenges for medical education and healthcare. A survey on DACA was administered online using Qualtrics Software System to 121 unique U.S.-MD granting medical school admissions leadership using e-mails between January 2018 and April 2018. A total of 39 individuals out of 121 (32%) responded to the survey; 23 (59%) of respondents identified as medical school admissions deans, 11 (28%) identified as directors and 5 (13%) as staff/officers. During the past 4 years, 19 (49%) reported having accepted DACA students. The majority either incorrectly answered or were otherwise unsure about the effect of DACA on medical education. The correlation between perception of understanding DACA and mean knowledge composite score was 0.38, P

Hispanics represent the largest and one of the fastest growing minority populations in the U.S. and have lower survival from colorectal cancer (CRC) than non-Hispanic Whites (NHW). We aimed to examine screening modalities, predictors, and regional disparities among Hispanics and NHW in the U.S. by conducting a cross-sectional analysis of Hispanic participants age 50 to 75 from the 2016 Behavioral Risk Factor Surveillance System (BRFSS) survey. The primary outcome was self-reported CRC screening status. We used the Rao-Scott Chi-square test to compare screening rates and modalities in NHWs and Hispanics. We also used univariable and multivariable logistic regression to determine predictors of screening among Hispanics and calculated Hispanic-NHW screening rate differences for each U.S. state/territory as a measure of regional screening disparities. The screening rate was 53.4% for Hispanics (N=12,395), compared to 70.4% for NHWs (N=186,331) (p

Purpose As racial and ethnic heterogeneity in the United States increases, it is important that the health care workforce, including surgery, mirror that diversity. Structural and perceptual barriers may contribute to an underrepresentation of African American and Latino surgeons. Understanding these barriers may translate into interventions and, in turn, improved diversification of the U.S. surgery workforce. Method In 2016, the authors conducted in-depth semistructured interviews, exploring structural and perceptual barriers that African American and Latino surgeons face. The authors used conventional qualitative techniques to analyze data and identify themes. Results The authors interviewed 23 participants and observed three major themes characterizing the path to becoming a surgeon: creating a path to medicine, surgical culture, and mentorship. Subthemes provided further nuance. For creating a path to medicine, the subthemes were personal attributes, family support, community assets/barriers, and minority experience. For surgical culture, the subthemes comprised quality of life, surgeon-patient relationship, and restoring health. For mentorship, the subthemes were aspirational figures, formal programs/peer support, and professional opportunities. Experiences described by African Americans and Latinos were similar, but the experiences of participants of different self-identified childhood socioeconomic status were dissimilar. Conclusions The path to a surgical career as experienced by African American and Latino surgeons is heavily influenced by mentors mediating their integration into surgical culture and engendering a feeling of belonging. Future surgeons from groups underrepresented in medicine would benefit from identifying aspirational figures early, a structured introduction into the rigors of the profession, and a deconstruction of negative surgical norms.

Despite the well-described benefits of cardiac rehabilitation (CR) on long-term health outcomes, CR is a resource that is underutilized by a significant proportion of patients that suffer from cardiovascular diseases. The main purpose of this study was to examine disparities in CR referral and participation rates among individuals from rural communities and racial and ethnic minority groups with coronary heart disease (CHD) when compared to the general population. A systematic search of standard databases including MedlLine, PubMed, and Cochrane databases was conducted using keywords that included cardiac rehabilitation, women, race and ethnicity, disparities, and rural populations. Twenty-eight clinical studies from 1990 to 2017 were selected and included 478,955 patients with CHD. The majority of available clinical studies showed significantly lower CR referral and participation rates among individuals from rural communities, women, and racial and ethnic groups when compared to the general population. Similar to geographic region, socioeconomic status (SES) appears to directly impact the use of CR programs. Patients of lower SES have significantly lower CR referral and participation rates than patients of higher SES. Data presented underscores the need for systematic referrals using electronic health records for patients with CHD in order to increase overall CR referral and participation rates of minority populations and other vulnerable groups. Educational programs that target healthcare provider biases towards racial and ethnic groups may help attenuate observed disparities. Alternative modalities such as home-based and internet-based CR programs may also help improve CR participation rates among vulnerable populations.

Introduction Biologic immunosuppression and HIV infection both carry risks of infection and malignancy. Small series suggest that patients living with well-controlled HIV may safely and efficaciously use biologics, like TNF-alpha inhibitors (TNF-I). However, no current U.S. guidelines exist to screen for HIV infection among high-risk groups prior to starting TNF-I. We describe the case of a patient who received TNF-I for Crohn’s Disease without any HIV testing, who developed potentially avoidable extensive Kaposi Sarcoma. Case Description A healthy 32-year-old man presented with 1 month of diarrhea and a 15-lb weight loss. Fecal calprotectin, ESR, and CRP were markedly elevated. Endoscopy demonstrated severe rectal inflammation with perirectal abscess and perianal skin tags, suggestive of inflammatory bowel disease. Biopsies showed active colitis with ulceration, cryptitis, and fibropurulent debris without evidence of granulomata, dysplasia, or CMV. He was treated with IV antibiotics, IV steroids, and 2 infusions of infliximab at 5 mg/kg. He continued to have 4 loose stools an hour, limiting his steroid wean. One month later, he developed painful, violaceous plaques on his face, buccal mucosa, torso, and lower extremities. Biopsy showed Kaposi Sarcoma, and HIV test was positive, with viral load 3292 and CD4 count 248. Although in a monogamous relationship with his husband, a well-recognized risk factor for HIV acquisition, he had never been tested for HIV. Antiretroviral therapy was initiated promptly. Repeat rectal biopsies stained positive for HHV-8 and CMV, concerning for rectal KS and CMV proctitis. He started valgancyclovir but self-increased prednisone, with poor symptom relief. Review of the initial endoscopy confirmed no obvious HHV-8 positivity. Three weeks after HIV diagnosis, he developed new red nodules across his chest, suspicious for worsening KS due to immune reconstitution inflammatory syndrome (IRIS). He completed 12 cycles of chemotherapy and had no sign of residual IBD on recent colonoscopy. KS is his presumed original diagnosis. Discussion Current U.S. guidelines do not recommend HIV screening prior to TNF-I use, despite the heightened risks of cumulative immune dysregulation. Our patient should have been screened annually for HIV according to CDC guidelines. Further, his uncontrolled HIV infection in combination with TNF-I and high dose steroids led to life-threatening Stage IV malignancy (KS), complicated by immune reconstitution inflammatory syndrome and poor ART absorption. We propose that all patients should be screened for common risk factors for HIV acquisition, such as men who have sex with men or intravenous drug use. For high risk patients, gastroenterologists should consider screening for HIV, in addition to tuberculosis and hepatitis, prior to immunosuppression with TNF-I.

BackgroundCardiovascular disease (CVD) is the leading cause of death among Latinos. Designing and delivering culturally appropriate interventions are critical for modifying behavioral and nutritional behavior among Latinos and preventing CVD.ObjectiveThis literature review provides information on evidence-based behavioral intervention strategies developed for and tested with at-risk Latinos, which reported impacts on biological outcomes.MethodsA literature search was performed in PubMed that identified 110 randomized controlled trials of behavioral interventions for CVD risk reduction with at-risk Latinos (≥1 CVD risk factor, samples >30% Latino), four of which met the inclusion criteria of reporting biological outcomes (BP, cholesterol, low density lipoprotein (LDL), high density lipoprotein (HDL), and body mass index (BMI)).ResultsAll the studies used promotoras (Hispanic/Latino community member with training that provides basic health education in the community without being a professional healthcare worker) to deliver culturally appropriate interventions that combined nutritional and physical activity classes, walking routes, and/or support groups. One study reported statistically significant reductions in systolic blood pressure and an increase in physical activity. One study reported reductions in cholesterol levels compared to the control group. Two studies did not have significant intervention effects. Most studies demonstrated no significant changes in LDL, HDL, or BMI. Methodological limitations include issues related to sample sizes, study durations, and analytic methods.ConclusionFew studies met the inclusion criteria, but this review provides some evidence that culturally appropriate interventions such as using promotoras, bilingual materials/classes, and appropriate cultural diet and exercise modifications provide potentially efficacious strategies for cardiovascular risk improvement among Latinos.

There are no effective medical treatments for WHO grade III (anaplastic) meningioma. Patients with this high-grade malignancy have a median survival of less than two years. Therapeutics that modulate the mechanisms that inhibit local immune responses in the tumor microenvironment are showing significant and durable clinical responses in patients with treatment refractory high-grade tumors. We examined the immune infiltrate of 291 meningiomas including WHO grade I-III meningiomas using immunohistochemistry and we examined the expression of PD-L1 mRNA by RNAscope in situ hybridization and PD-L1 protein by immunohistochemistry. In meningioma, the tumor infiltrating lymphocytes are predominantly T cells. In anaplastic meningioma, there is a sharp decrease in the number of T cells, including the numbers of CD4+ and CD8+ T cells and cells expressing PD-1 and there is also an increase in the number of FOXP3 expressing immunoregulatory (Treg) cells. PD-L1 expression is increased in anaplastic meningioma - both mRNA and protein. Using patient derived meningioma cell, we confirm that PD-L1 is expressed in meningioma cells themselves, and not solely in infiltrating immune cells. This work indicates that high-grade meningioma harbor an immunosuppressive tumor microenviroment and that increased Treg cells and elevated PD-L1 may contribute to the aggressive phenotype of these tumors.
