ABSTRACT Importance Rural-urban disparities in chronic disease prevalence are well established; however, the extent to which individual-level socioeconomic status (SES) contributes to these disparities remains unclear. Objective To examine the associations of rurality and SES with the prevalence of five most burdensome chronic diseases among adults. Design We conducted a retrospective cross-sectional study of adults across 27 Upper Midwest counties using the Expanded Rochester Epidemiology Project (E-REP) medical record data linkage system to evaluate associations between rurality, SES and chronic disease prevalence. Prevalence of clinically diagnosed asthma, diabetes, hypertension, coronary heart disease, and mood disorders was identified from International Classification of Diseases ICD9/10 codes over a five-year period (2014-2019). Setting Population based Participants Adults over 18 years residing in the 27 E-REP counties, excluding those missing rural-urban residence status. Exposure HOUSES index, an individual-level measure of SES, served as the primary measure, while rurality based on Rural Urban Commuting Area (RUCA) codes 4-10 was the secondary measure. Main Outcome Prevalence of the five clinically diagnosed chronic diseases was identified using ICD9/10 codes from 2014–2019. Mixed effect logistic regression models were used and adjusted for demographics and general medical examination receipt, to assess rural-urban and SES differences for prevalence of each chronic disease. Results Among 455,802 adults with available HOUSES index, 42.8% lived in rural areas, 53.8% were female and 87.4% were non-Hispanic White. In the unadjusted analysis, rural and urban populations showed comparable asthma and CHD prevalence, while mood disorders, hypertension, and diabetes were more common in urban areas. After adjusting for demographic factors and healthcare utilization, rural-urban differences were no longer statistically significant, whereas SES remained strongly associated with all diseases in a dose response manner (e.g., adjusted Odds Ratio for hypertension (ref: HOUSES index Q4): 1.14, 1.27, and 1.42 for HOUSES index Q3, Q2, and Q1, respectively). Conclusions and Relevance Individual-level SES measured by the HOUSES index, was more strongly associated with chronic disease prevalence than rurality, supporting its integration into population health assessment and risk stratification.

Abstract Background Cancer therapies have prolonged survival in lymphoma. However, lymphoma patients may develop significant coronary artery disease (CAD), which may be treated by percutaneous coronary intervention (PCI). The characteristics and outcomes of lymphoma patients treated by PCI are not well studied. Methods We reviewed lymphoma patients undergoing PCI at our institution between 2010 and 2020 and compared them to a cohort without cancer. Patient characteristics and predictors of long-term mortality and major adverse cardiac events (MACE) (death, myocardial infarction, target lesion revascularization) were studied using descriptive statistics and survival analysis utilizing a Cox proportional hazards model. Results Of the 11,953 patients in the study cohort, 83 had a history of lymphoma meeting study criteria. Lymphoma patients, as compared to non-lymphoma patients were similar with respect to age, sex, hypertension, diabetes, hyperlipidemia, prior MI, and prior PCI (all p=ns). Over a median follow-up of 3.9 (1.0, 5.0) years, the mortality at 5 years was higher in lymphoma versus non-lymphoma patients (47.5% vs 29.8%) (P=0.005) (Figure). After adjusting for age, sex, hypertension, diabetes, shock, smoking status, heart failure, and chronic renal disease, lymphoma was an independent predictor of mortality (OR 1.59; 95% CI 1.07-2.36, p=0.02). Lymphoma was not independently associated with MACE. Discussion Lymphoma patients undergoing PCI have significantly lower survival rates than non-cancer controls. After accounting for important cardiac risk factors, lymphoma was independently associated with higher long term mortality.

AbstractBackgroundElevated transmitral gradient post transcatheter mitral valve edge‐to‐edge repair (TEER) has been associated with worse outcomes. Whether an elevated baseline transmitral diastolic mean gradient (MG) ≥5 mmHg is associated with hemodynamic outcomes after TEER is unknown.MethodsA total of 164 consecutive patients undergoing TEER at Mayo Clinic between June 2014 and May 2018 were analyzed in this retrospective study. Baseline demographics, as well as clinical, echocardiographic, and procedural data were obtained. Data on direct left atrial pressure (LAP) before and after TEER were recorded. Logistic regression models were constructed to evaluate the association between preprocedure transmitral diastolic mean gradient (pre‐MG) and (1) improvement in LAP following TEER, (2) postprocedure transmitral diastolic mean gradient (post‐MG). A decrease in LAP post TEER was considered an improvement in hemodynamic response. Pre‐MG was categorized as: ≥5 and <5 mmHg.ResultsMedian age of the cohort was 81.5 years (Q1: 76.3, Q3: 87) and 34% were female. At baseline, median transmitral diastolic MG was 4 mmHg (Q1: 3, Q3: 5) and median LAP was 19 mmHg (Q1:16, Q3: 23.5). In a multivariable model, adjusted for age and sex, patients with pre‐MG ≥ 5 mmHg were less likely to see an improvement in LAP post TEER (adjusted odds ratio [aOR]: 0.22, 95% confidence interval [CI]: 0.09, 0.55; p = 0.001) and more likely to have elevated post‐MG (aOR; 7.08, 95% CI: 2.93, 17.13; p < 0.001).ConclusionHigher pre‐MG (≥5 mmHg) was associated with a lower reduction in LAP and higher residual transmitral gradient following TEER suggesting other potential contributors to increased LAP besides mitral regurgitation as a cause of elevated baseline MG.

SummaryBackgroundAlthough bloating is a highly prevalent and troublesome symptom in irritable bowel syndrome with constipation (IBS‐C), treatment is empirical with no specific guidelines for its management.AimTo conduct a pairwise and network meta‐analysis, using a frequentist approach, of Food and Drug Administration‐licensed drugs for IBS‐C comparing their efficacy for abdominal bloating as a specific endpoint.MethodsWe searched the medical literature through December 2020 to identify randomised controlled trials (RCTs) in IBS‐C, with abdominal bloating reported as a dichotomous assessment. Efficacy of each drug was reported as a pooled relative risk (RR) with 95% confidence intervals (CIs) to summarise effect of each comparison tested. Treatments were ranked according to their P‐score.ResultsWe identified 13 eligible RCTs, containing 10 091 patients. Linaclotide 290 µg o.d., lubiprostone 8 µg b.d., tenapanor 50 mg b.d. and tegaserod 6 mg b.d. were all superior to placebo for abdominal bloating in patients with IBS‐C, in both pairwise and the network meta‐analyses. Linaclotide demonstrated the greatest improvement in abdominal bloating in both pairwise and network meta‐analysis (RR of failure to achieve an improvement in abdominal bloating = 0.78; 95% CI 0.74‐0.83, number needed to treat = 7, P‐score 0.97). Indirect comparison revealed no significant differences between individual drugs.ConclusionsWe found all licensed drugs for IBS‐C to be superior to placebo for abdominal bloating. Linaclotide appeared to be the most efficacious at relieving abdominal bloating. Further research is needed to assess long‐term efficacy of these agents and to better understand the precise mechanism of improving bloating.
