Intestinal Metaplasia Associated with Symptoms of Dyspepsia.

Background: Peptic ulcer disease (PUD) and Helicobacter pylori (HP) are associated with dyspepsia, but the role of gastric intestinal metaplasia (IM) has not been described. The objective of this study is to examine the association between gastric IM and dyspepsia. Methods: We developed a cohort of consecutive patients referred to gastroenterology between Jan 2019 and July 2020 for dyspepsia and iron deficiency anemia (IDA) and completed an upper endoscopy with biopsies in a safety-net health system. The primary outcome was the prevalence of gastric IM in patients with dyspepsia compared to IDA. Secondary outcomes included prevalence of HP, chronic gastritis (CG) and chronic active gastritis (CAG) in the dyspepsia and IDA groups. A multivariable analysis was performed to assess the independent association between gastric IM and dyspepsia. Results: Compared to the IDA cohort (n = 366), patients with dyspepsia (n = 349) were more likely to be female (65% vs. 47%, p < 0.01), harbor gastric IM (20.3% vs. 14.2%, p = 0.03), and less likely to have CAG (12.0% vs. 26.5%, p < 0.01) or HP (10.9% vs. 21.3%, p < 0.01). After adjusting for pathological findings, race, ethnicity, gender and age, the association strengthened between IM and dyspepsia (adj OR 1.81 from OR 1.54, 95% CI 1.19-2.76, p < 0.01). Conclusions: We observed a significant relationship between the presence of gastric IM and dyspepsia symptoms, which increased after adjusting for confounding factors. Future studies should verify the relationship between IM and dyspepsia, the effect of IM regression, and possible mediators of gastric IM on symptoms.

TNF-α inhibition in the setting of undiagnosed HIV infection: a call for enhanced screening guidelines.

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.

A Collaboration Among Primary Care-Based Clinical Pharmacists and Community-Based Health Coaches.

BACKGROUND/OBJECTIVES: Medication 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. DESIGN: Retrospective cohort study using propensity score matching. SETTING: Urban academic medical center and surrounding community. PARTICIPANTS: Intervention 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. INTERVENTION: Following 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. MEASUREMENTS: Thirty-day readmissions (primary outcome), 60- and 90-day readmissions, and 30-day emergency department (ED) visits (secondary outcomes) to UCLA Health. RESULTS: Among 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 < .001). CONCLUSION: A home visit conducted by a health coach combined with a medication review by a primary care-based pharmacist may prevent subsequent inpatient utilization.

Colorectal cancer screening among Hispanics in the United States: Disparities, modalities, predictors, and regional variation.

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 < 0.001). Among Hispanics, colonoscopy was most common (75.9%). Uninsured status (aOR = 0.51; 95% CI = 0.38-0.70) and limited access to medical care (aOR = 0.38; 95% CI = 0.29-0.49) predicted lack of screening. States/territories with the largest screening disparities were North Carolina (33.9%), Texas (28.3%), California (25.1%), and Nebraska (25.6%). Disparities were smallest in New York (2.6%), Indiana (3.1%), and Delaware (4.0%). In Ohio and Guam, Hispanics had higher screening rates than NHWs. In conclusion, Hispanics have lower CRC screening rates than NHWs across most U.S. states/territories; however, the disparity varies by region. Future efforts must address multi-level barriers to screening among Hispanics and target regions with low rates to improve CRC outcomes in this growing population.

The Termination of Deferred Action for Childhood Arrival (DACA) Protections and Medical Education in the U.S.

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 < 0.05. This study found that U.S.-MD granting medical school admissions leaders self-reported knowledge was moderately correlated with actual knowledge about DACA.

Disparities in Cardiac Rehabilitation Among Individuals from Racial and Ethnic Groups and Rural Communities-A Systematic Review.

PURPOSE: 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. METHODS: 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. RESULTS: 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. CONCLUSIONS: 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.

New enrollment under the affordable care act: leading the way for community health centers in Southern California.

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.

Perceptual and Structural Facilitators and Barriers to Becoming a Surgeon: A Qualitative Study of African American and Latino Surgeons.

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.

Efficacy of Behavioral Interventions on Biological Outcomes for Cardiovascular Disease Risk Reduction among Latinos: a Review of the Literature.

BACKGROUND: Cardiovascular 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. OBJECTIVE: This literature review provides information on evidence-based behavioral intervention strategies developed for and tested with at-risk Latinos, which reported impacts on biological outcomes. METHODS: A 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)). RESULTS: All 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. CONCLUSION: Few 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.

Increased expression of the immune modulatory molecule PD-L1 (CD274) in anaplastic meningioma.

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.
