Social Determinants of Health in Diverticulitis: A Systematic Review.

BACKGROUND: There is growing interest in social determinants of health for surgical populations. Within diverticulitis, no systematic collation of available evidence has been performed. OBJECTIVE: To assess frequency, variety, and association directions for social determinants of health in colonic diverticular disease. DATA SOURCES: Four electronic databases were queried: PubMed, Embase, Cochrane, and Web of Science. STUDY SELECTION: Included studies reported symptomatic left-sided colonic diverticular disease with respect to a social determinant of health according to the Healthy People 2030 initiative or applicable proxy variable. Studies with non-English full text, cohort size fewer than 50, pediatric cohorts, and exclusively non-left sided disease were excluded. MAIN OUTCOME MEASURES: Quality assessment through modified Newcastle-Ottawa scale, frequency of variables reported, and effect size trends for common comparisons. RESULTS: Among 50 included studies, 40 were good and 10 were fair in quality. Social determinants of health in diverticulitis were identified across Economic Stability, Education Access and Quality, Health Care Access and Quality, Neighborhood and Built Environment, and Social and Community Context domains. The two most common variables were self-reported race and ethnicity (n = 33) and insurance (n = 22). Among 18 unique studies reporting comparisons of white versus any other self-reported race and ethnicity, twelve identified a disparity disadvantaging non-white groups with effect sizes (95% confidence interval ranging from 1.23 [1.10 -1.37] to 5.35 [1.32 - 21.61]). Among 15 unique studies reporting a non-private versus private insurance comparison, nine identified non-private insurance as a risk factor with effect sizes (95% confidence intervals ranging from 1.15 [1.02 - 1.29] to 3.83 [3.01 - 4.87]). LIMITATIONS: Retrospective studies, heterogeneity across cohort and variable definitions. CONCLUSIONS: Social determinants of health domains are associated with a variety of diverticulitis outcomes. Additional studies are needed to address infrequently reported domains and identify optimal strategies for intervening in clinical settings. PROSPERO ID: CRD42023422606.

Diuretic Responsiveness and Its Prognostic Significance in Children With Heart Failure.

BACKGROUND: Loop diuretics are considered first-line therapy for congestion in children with heart failure, although some patients remain volume overloaded during treatment. We sought to characterize loop diuretic responsiveness (DR) in children hospitalized with acute decompensated failure and to determine whether a decreased response was associated with worse outcomes. METHODS AND RESULTS: DR was calculated for 108 consecutive children ˂21 years of age who were hospitalized with acute decompensated heart failure. DR was defined as net fluid (mL) output per 1 mg of furosemide equivalents during the first 72 hours of treatment with a loop diuretic. The primary outcome was the composite end point of inpatient death or use of mechanical circulatory support. The median DR was 6.0 mL/mg (interquartile range -2.4 to 15.7 mL/mg). Thirty-two percent of patients remained in a positive fluid balance after 72 hours of treatment with a loop diuretic. Death or use of mechanical circulatory support occurred in 29 patients (27%). Low DR was associated with the composite end point, even after adjusting for net urine output and loop diuretic dose indexed to weight (odds ratio 5.3; P = .003). Patients with low DR also experienced longer length of hospital stay than patients with greater DR (median 33 days vs 11 days; P = .002). CONCLUSION: In children hospitalized with acute decompensated heart failure, early diminished loop DR during decongestion therapy is common and portends a poor prognosis.

Decision Aid for Colectomy in Recurrent Diverticulitis: Development and Usability Study.

BACKGROUND: Diverticular disease is a common gastrointestinal diagnosis with over 2.7 million clinic visits yearly. National guidelines from the American Society of Colon and Rectal Surgeons state that "the decision to recommend elective sigmoid colectomy after recovery from uncomplicated acute diverticulitis should be individualized." However, tools to individualize this decision are lacking. OBJECTIVE: This study aimed to develop an online educational decision aid (DA) to facilitate effective surgeon and patient communication about treatment options for recurrent left-sided diverticulitis. METHODS: We used a modified design sprint methodology to create a prototype DA. We engaged a multidisciplinary team and adapted elements from the Ottawa Personal Decision Guide. We then iteratively refined the prototype by conducting a mixed methods assessment of content and usability testing, involving cognitive interviews with patients and surgeons. The findings informed the refinement of the DA. Further testing included an in-clinic feasibility review. RESULTS: Over a 4-day in-person rapid design sprint, including patients, surgeons, and health communication experts, we developed a prototype of a diverticulitis DA, comprising an interactive website and handout with 3 discrete sections. The first section contains education about diverticulitis and treatment options. The second section clarifies the potential risks and benefits of both clinical treatment options (medical management vs colectomy). The third section invites patients to participate in a value clarification exercise. After navigating the DA, the patient prints a synopsis that they bring to their clinic appointment, which serves as a guide for shared decision-making. CONCLUSIONS: Design sprint methodology, emphasizing stakeholder co-design and complemented by extensive user testing, is an effective and efficient strategy to create a DA for patients living with recurrent diverticulitis facing critical treatment decisions.

The effects of lifestyle changes on serum lipid levels in children in a real life setting.

OBJECTIVE: Studies have shown improvement in lipid levels after institution of lifestyle changes in children enrolled in closely monitored programs. There programs are difficult to mimic in real world clinics. We aim to determine if diet and exercise result in improvement in lipid levels in patients seen in a designated lipid clinic in a real life setting. DESIGN: Retrospective review of patients followed for dyslipidemia at the Texas Children's Hospital Lipid Clinic from May 1, 2012 to May 1, 2015. Patients included were seen more than once, had repeat lipid testing, and abnormal baseline lipid levels. Multivariate analysis using mixed models were performed to compare outcomes in patients who did and did not participate in lifestyle change. RESULTS: Of the 268 patients seen within the study period, 174 (56% male, 44% female) met inclusion criteria. Median age was 11 years. Compared to patients who did not make lifestyle changes: patients who made only diet changes demonstrated significant improvement in weight only (slope = -1.55, P-value = .014), and those who made only exercise changes demonstrated significant improvements in serum cholesterol (slope = -22.8, P-value = .017) and non-HDL cholesterol (slope = -28.7, P-value = < .01) levels. Patients who participated in both diet and exercise demonstrated significant improvement in weight (slope = -1.13, P-value = .011), diastolic blood pressure (slope = -1.82, P-value = < .01), and serum lipid levels: LDL (slope = -10.8, P-value = 0.017), HDL (slope = 1.52, P-value = .24), Triglycerides (slope = -0.11, P-value = .033) compared to those who did not make lifestyle changes. CONCLUSIONS: Outpatient management of dyslipidemia is difficult. Only patients who participated in both diet and exercise showed significant improvement in outcomes when compared to those who did not make lifestyle changes.
