The association between diabetes and gallstones: a nationwide population-based cohort study

Introduction

Evidence regarding the association between diabetes mellitus (DM) and cholelithiasis is still inconsistent.

Aim

To examine the association between diabetes and gallstones and the commonly associated factors in a nationwide population-based cohort investigation.

Material and methods

The demographic and outcome variable data were extracted from the National Health and Nutrition Examination Survey (NHANES) database for the years 2017-2018.

Results

A total of 5376 individuals were included in the final analysis, with a mean age of 51.3 ±17.8 years. Females constituted 51.5% of the included individuals, and the overall mean body mass index (BMI) was 29.8 ±7.4 kg/m2. The prevalence of diabetes was 16.2% among the included individuals, with a mean age of 50.6 ±13.6 years at diagnosis of diabetes, and only 4.5% were taking insulin. The prevalence of cholelithiasis was 11.2%, with a mean age of 44.4 ±16.1 years at diagnosis, and 11.3% had previous cholecystectomy (gallbladder surgery.) There was a significant increase in gallstone rates among diabetic patients as compared to non-diabetics in the unadjusted (OR = 2.30; 95% CI: 1.89-2.79; p < 0.001) and adjusted (OR = 1.52; 95% CI: 1.20-1.92; p < 0.001) models. Moreover, this association was not time-dependent where the "age when first told you had diabetes" did not show a significant influence on the gallstone rate, whether in unadjusted (OR = 1.01; 95% CI: 1.00-1.02; p = 0.221) or adjusted (OR = 1.01; 95% CI: 0.99-1.03; p = 0.395) models. Furthermore, insulin usage was found to be a significant predictor of cholelithiasis, whether in unadjusted (OR = 2.39; 95% CI: 1.74-3.28; p < 0.001) or adjusted (OR = 1.52; 95% CI: 1.05-2.19; p = 0.026) models.

Conclusions

DM and insulin therapy are possible risk factors for developing cholelithiasis.

Health disparities in COVID-19: immune and vascular changes are linked to disease severity and persist in a high-risk population in Riverside County, California

BACKGROUND

Health disparities in underserved communities, such as inadequate healthcare access, impact COVID-19 disease outcomes. These disparities are evident in Hispanic populations nationwide, with disproportionately high infection and mortality rates. Furthermore, infected individuals can develop long COVID with sustained impacts on quality of life. The goal of this study was to identify immune and endothelial factors that are associated with COVID-19 outcomes in Riverside County, a high-risk and predominantly Hispanic community, and investigate the long-term impacts of COVID-19 infection.

METHODS

112 participants in Riverside County, California, were recruited according to the following criteria: healthy control (n = 23), outpatients with moderate infection (outpatient, n = 33), ICU patients with severe infection (hospitalized, n = 33), and individuals recovered from moderate infection (n = 23). Differences in outcomes between Hispanic and non-Hispanic individuals and presence/absence of co-morbidities were evaluated. Circulating immune and vascular biomarkers were measured by ELISA, multiplex analyte assays, and flow cytometry. Follow-up assessments for long COVID, lung health, and immune and vascular changes were conducted after recovery (n = 23) including paired analyses of the same participants.

RESULTS

Compared to uninfected controls, the severe infection group had a higher proportion of Hispanic individuals (n = 23, p = 0.012) than moderate infection (n = 8, p = 0.550). Disease severity was associated with changes in innate monocytes and neutrophils, lymphopenia, disrupted cytokine production (increased IL-8 and IP-10/CXCL10 but reduced IFNλ2/3 and IFNγ), and increased endothelial injury (myoglobin, VCAM-1). In the severe infection group, a machine learning model identified LCN2/NGAL, IL-6, and monocyte activation as parameters associated with fatality while anti-coagulant therapy was associated with survival. Recovery from moderate COVID infection resulted in long-term immune changes including increased monocytes/lymphocytes and decreased neutrophils and endothelial markers. This group had a lower proportion of co-morbidities (n = 8, p = 1.0) but still reported symptoms associated with long COVID despite recovered pulmonary function.

CONCLUSION

This study indicates increased severity of COVID-19 infection in Hispanic individuals of Riverside County, California. Infection resulted in immunological and vascular changes and long COVID symptoms that were sustained for up to 11 months, however, lung volume and airflow resistance was recovered. Given the immune and behavioral impacts of long COVID, the potential for increased susceptibility to infections and decreased quality of life in high-risk populations warrants further investigation.

Social vulnerability, medical care access and asthma related emergency department visits and hospitalization: An observational study

BACKGROUND

The Social Vulnerability Index (SVI) is a publicly available dataset to identify communities in greatest need of resources.

OBJECTIVE

To examine the utility of using the county-level SVI as predictors of asthma-related outcomes.

METHODS

We used the American Community Survey-derived SVI and the National Environmental Public Health Tracking Network - Query Tool to retrieve data for all counties with available SVI data and at least one matched outcome of interest. Then, we tested SVI as a predictor for emergency department visits (EDV) and hospitalizations, with investigating disparities in primary care physician (PCP) density and emergency department physicians (EDP) density. Linear and logistic regression models were used.

RESULTS

Compared to counties of the lowest SVI quartile, counties of mid-low, mid-high, and highest SVI quartiles had 1%, 4%, and 5% higher odds of asthma-related EDV per 10,000 population, respectively, and 4%, 21%, and 24% higher odds of asthma-related hospitalization per 10,000 population, respectively. Moreover, the data showed an apparent resources mismatch between the EDP densities per 10,000 populations and the SVI quartiles, and the effect of the county level SVI on the asthma-related EDV and hospitalization is not strongly affected by PCP or EDP densities.

CONCLUSION

The counties with the highest SVI -and the most vulnerable to asthma hazards- have a lower coverage of PCP and EDP. Interventions directed to address persistent social vulnerability would offer the opportunity of primary prevention with less exhaustion for the medical resources.

Does teaching Optimism lower Burnout in residency training- a pilot study

Background: Residents frequently experience burnout. Multiple interventions to decrease the risk of burnout have had inconsistent results. In non-medical settings, improving optimism promotes a positive outlook and enhances well-being. Thus, psychological interventions that improve optimism could have potential to decrease the risk for burnout.

Objective: Using Lazarus’ Ways of Coping as an organizational framework, this intervention sought to evaluate the impact of an optimism curriculum on residents’ burnout.

Methods: Thirty-six Internal Medicine residents participated in an optimism improvement program from November 2019 to April 2020. We determined pre- and post-curriculum measures of optimism, happiness, and burnout with validated surveys. The Optimism Curriculum was comprised of three one-hour long sessions, which included lectures, group and self-reflective exercises. A post - curriculum evaluation rating the effectiveness of the program was administered separately.

Results: Thirty-four out of thirty-six residents completed the post curricular surveys. Individuals with low optimism scores had a higher score for burnout compared to those with higher optimism scores. The post-intervention survey showed numerical improvement in optimism, happiness and burnout, although these changes were not statistically significant. The post-intervention survey showed a decrease in the measure of burnout; however, this was not significant (p = 0.24) with an effect size of 0.34 (Cohen’s d).

Conclusions: Teaching optimism to residents with the objective of decreasing the risk of burnout is feasible and easily integrated into residency education sessions. The encouraging results of this pilot study lay the foundation for additional studies and suggest a practical role for implementing optimism curricula in residency training programs.
