Objective: Our objectives were two-fold: 1) To evaluate the benefits of population health strategies focused on social determinants of health and integrated into the primary care medical home (PCMH) and 2) to determine how these strategies impact diabetes and cardiovascular disease outcomes among a low-income, primarily minority community. We also investigated associations between these outcomes and emergency department (ED) and inpatient (IP) use and costs.
Design: Retrospective cohort.
Setting: Community-based PCMH: Baylor Scott & White Health and Wellness Center (BSW HWC).
Patients/participants: All patients who attended at least two primary care visits at BSW HWC within a 12-month time span from 2011-2015.
Methods: Outcomes for patients participating in PCMH only (PCMH) as compared to PCMH plus population health services (PCMH+PoPH) were compared using electronic health record data.
Main Outcomes: Diastolic and systolic blood pressure, hemoglobin A1c, ED visits and costs, and IP hospitalizations and costs were examined.
Results: From 2011-2015, 445 patients (age=46±12 years, 63% African American, 61% female, 69.5% uninsured) were included. Adjusted regression analyses indicated PCMH+PoPH had greater improvement in diabetes outcomes (prediabetes HbA1c= -.65[SE=.32], P=.04; diabetes HbA1c= -.74 [SE=.37], P<.05) and 37% lower ED costs than the PCMH group (P=.01). Worsening chronic disease risk factors was associated with 39% higher expected ED visits (P<.01), whereas improved chronic disease risk was associated with 32% fewer ED visits (P=.04).
Conclusions: Integrating population health services into the PCMH can improve chronic disease outcomes, and impact hospital utilization and cost in un- or under-insured populations.

Servei d'Aparell Digestiu, Hospital Universitari Germans Trias i Pujol (Badalona, Catalonia, Spain).
Background And Aims: Inflammatory bowel disease (IBD) develops in genetically susceptible individuals exposed to certain environmental factors, of which only a few have been established. We aimed to assess whether bariatric surgery (BS) and severe obesity are associated with an increased risk of developing IBD.
Methods: Adults diagnosed with obesity or severe obesity between 2005 and 2020 were identified from the Catalan Health Surveillance System; those diagnosed with IBD prior to the diagnosis of obesity or severe obesity were excluded.

Background: Chronic constipation, diarrhea, and fecal incontinence (FI) are prevalent with significant impact on quality of life and healthcare utilization. Thyroid dysfunction was recognized as a potential contributor to bowel disturbances in selected populations, but the strength/consistency of this association remain unclear.
Aims: To investigate the relationship between thyroid function and bowel health measures (constipation, diarrhea, and FI) in a nationally representative sample of the U.

Background: Previous studies have suggested a potential role of estrogen in the pathophysiology of chronic kidney disease (CKD); however, the association and causality between estrogen and kidney function remain unclear.
Methods: The cross-sectional correlation between serum estradiol concentration and estimated glomerular filtration rate (eGFR) and urinary albumin-to-creatinine ratio (ACR) was analyzed using data from the National Health and Nutrition Examination Survey 2013-2016. Causality was tested using mutual bidirectional Mendelian randomization (MR) approaches based on six large-scale GWAS studies.

Purpose: Radiotherapy (RT) for oropharyngeal cancer (OPC) can lead to late toxicity. Fatigue is a known debilitating issue for many cancer survivors, yet prevalence and severity of long-term fatigue in patients treated for OPC is unknown.
Method: As part of a mixed-methods study, fatigue in OPC patients ≥ 2 years post RT + / - chemotherapy was evaluated.
