RESUMO
COVID-19 has ravaged the medical, social, and financial landscape across the world, and the USA-Mexico border is no exception. Although some risk factors for COVID-19 severity and mortality have already been identified in various ethnic cohorts, there remains a paucity of data among Hispanics, particularly those living on borders. Ethnic disparities in COVID-19 outcomes in Hispanic and black populations have been reported. We sought to identify the clinical presentation, treatment, laboratory, and imaging characteristics of 82 Hispanic patients in a county hospital and describe the factors associated with rates of hospitalization, intensive care unit (ICU) admission, and mortality. The most common comorbidities were hypertension (48.8%) and diabetes mellitus (DM) (39%), both found to be associated with hospitalization and mortality, while only DM was associated with increased rate of ICU admission. Multivariable analysis showed that individuals with fever, low oxygen saturation (SpO2), nasal congestion, shortness of breath, and DM had an increased risk of hospitalization. Individuals with fever, decreased levels of SpO2, and advanced age were found to be associated with an increased risk of death. The most common cause of death was respiratory failure (28.9%), followed by shock (17.8%) and acute kidney injury (15.6%). Our findings are critical to developing strategies and identifying at-risk individuals in a Hispanic population living on borders. Research aiming to identify key evidence-based prognostic factors in our patient population will help inform our healthcare providers so that best interventions can be implemented to improve the outcomes of patients with COVID-19.
RESUMO
BACKGROUND: There have been conflicting reports comparing the prevalence of large polyps (>9 mm) between Hispanics and non-Hispanic whites (NHW). Differences between Hispanic subpopulations may account for these variations. AIMS: We aimed to assess the prevalence of large polyps (>9 mm) in Hispanics from Mexican- and non-Mexican-predominant states compared with NHW. As secondary outcome, we evaluated results by polyp location. METHODS: The 2010 U.S. Census Bureau was used to identify states with a predominantly Mexican Hispanic (West) versus non-Mexican Hispanic (East) populations. Average-risk colonoscopies in those states from 2001 to 2014 were accessed using the Clinical Outcomes Research Initiative database. Military and Veteran's Administration sites were excluded. Hispanics were compared with NHW in each geographical location using hierarchical logistic regression analysis. RESULTS: A total of 65,138 procedures were included with 33,425 procedures in the West (14.5% Hispanics) and 31,713 procedures in the East (44.0% Hispanics,). East Hispanics had significantly less odds of large polyps, OR 0.74, CI 0.58-0.94, p = 0.02, while West Hispanics exhibited no difference, OR 0.91, CI 0.76-1.10, p = 0.33, compared with NHW. Eastern Hispanics had less odds of large distal polyps, OR 0.69, CI 0.52-0.91, p = 0.01, and no difference in proximal polyps compared with NHW. Among Western Hispanics, no differences were seen in proximal, OR 1.06, CI 0.83-1.35, p = 0.66, or distal polyps, OR 0.83, CI 0.68-1.02, p = 0.08, compared with NHW. CONCLUSION: Using NHW as a reference, Hispanics from Mexican-predominant states have a similar prevalence of large polyps, while Hispanics from non-Mexican-predominant states have a lower prevalence. Differences in Hispanic subpopulations likely explain previous conflicting reports on the prevalence of large polyps in Hispanics and NHW.

OBJECTIVES: Helicobacter pylori is prevalent worldwide, especially in Latin America. Triple and quadruple antibiotic therapies have been relatively effective; however, resistance has emerged in recent years. The treatment success rate of these regimens on the border of the United States and Mexico is unknown. Our study attempted to determine eradication rates of two major regimens based on urea breath test (UBT) results in patients previously diagnosed as having H. pylori in a single center in El Paso, Texas, a city on the geographic border with Mexico. METHODS: This was a retrospective cohort study of adult patients with H. pylori who underwent UBT after being treated with triple therapy (amoxicillin/clarithromycin/proton pump inhibitor for 14 days), quadruple therapy (tetracycline/metronidazole/bismuth/proton pump inhibitor, usually for 10 days), or both for H. pylori from 2010 to 2015 in a county hospital. Patients were excluded if they did not complete therapy or if their treatment regimen was unknown. The Student t test and the χ2 test were used to analyze the data. The cumulative incidence and 95% confidence interval (CI) for treatment success were estimated. RESULTS: A total of 104 patients completed the treatment for H. pylori and had UBT. Mean age was 53 years, 76% were women, 85% were Hispanic, and mean body mass index was 30.5 kg/m2. Of the 104 patients diagnosed as having H. pylori, 88 received triple therapy (84.6%) and 16 received quadruple therapy: 12 (11.5%) standard quadruple therapy, 4 (3.9%) triple therapy plus metronidazole. There were no differences between groups regarding age, sex, body mass index, or ethnicity. Overall, 90 (86.5%, 95% CI 78-92) patients had negative UBT after initial treatment. Based on posttreatment UBT, the triple therapy group had a similar eradication rate compared with the quadruple therapy group (78/88, 88.6% vs 12/16, 75.0%, P = 0.22). Of the 14 patients with positive posttreatment UBT, 12 (85.7%) received retreatment (2 were lost to follow-up), 11 (91.7%) received quadruple therapy, and 1 (8.3%) received triple therapy. Eradication was successful in 9 of 12 (75%, 95% CI 43-95) patients at retreatment. As such, of the initial 104 patients, 99/104 (95.2%) achieved H. pylori eradication posttreatment (either initial or retreatment). CONCLUSIONS: In a predominantly Hispanic population on the US-Mexico border, H. pylori eradication rates based on UBT results were relatively high and were similar for triple therapy and quadruple therapy. Quadruple therapy was effective for those who failed the initial H. pylori treatment. This may have implications for cost-effective therapy in our region.
