Factors associated with inpatient complications among patients with obesity and COVID-19 at an urban safety-net hospital: A retrospective cohort study.

Objective: Obesity increases morbidity and mortality from Coronavirus disease 2019 (COVID-19). This study characterized inpatient complications among patients with obesity and COVID-19-including myocardial infarction, renal failure requiring dialysis, stroke, secondary bacterial infection, and venous thromboembolism-and identified factors associated with developing at least one inpatient complication at a safety-net hospital with a diverse cohort. Methods: A retrospective review was performed of all patients admitted for ≥3 days with COVID-19 between 16 March 2020, and 8 April 2020. Logistic regression identified factors associated with developing at least one COVID-19-related complication among patients with obesity (body mass index ≥30 kg/m2). Results: 374 patients were included; 53.7% were classified as having obesity, 43.9% identified as Black, and 38.5% identified as Latino or Hispanic. Obesity was not associated with having at least one inpatient complication on multivariable analysis, but increased age (aOR 1.02, [95% CI 1.01-1.04], p = 0.010) and obstructive sleep apnea (aOR 2.25, [1.08-4.85], p = 0.034) were associated with this outcome. Conclusions: Obesity was not associated with specified inpatient complications among patients with COVID-19 admitted to a health system caring for diverse patients. Future studies should incorporate larger cohorts and reflect newer treatment protocols.

Racial Disparities in Diabetes Technology Use and Outcomes in Type 1 Diabetes in a Safety-Net Hospital.

BACKGROUND: Limited data exist regarding diabetes technology use among adults with type 1 diabetes (T1D) in urban racially/ethnically diverse safety-net hospitals. We examined racial/ethnic differences in the use of continuous glucose monitor (CGM) and continuous subcutaneous insulin infusion (CSII) in this setting. METHODS: A retrospective review of 227 patients ≥ 18 years of age with T1D seen in an urban, safety-net endocrinology clinic during 2016-2017 was completed (mean age: 39; 80% English-speaking; 50% had public insurance). Diabetes technology use, defined as either CGM or CSII or both CGM and CSII, and clinical outcomes were examined by race/ethnicity. RESULTS: Overall, 30% used CGM and 26% used CSII. After adjusting for age, language, insurance, and annual income, diabetes technology use in non-White patients was significantly lower than in White patients, predominantly lower in Black (aOR 0.25 [95% CI 0.11-0.56]) and patients identified as other race/ethnicity (aOR 0.30 [95% CI 0.11-0.77]). At the highest household income level (≥$75,000/y), Black and Hispanic individuals were significantly less likely than White individuals to use diabetes technology (P < .0007). Mean hemoglobin A1c (HbA1c) was lower in patients using any diabetes technology compared with patients using no technology (P < .0001). Use of CGM and CSII together was associated with the lowest HbA1c across all racial/ethnic groups. CONCLUSIONS: Racial/ethnic disparities in diabetes technology use and glycemic control were observed even after adjusting for sociodemographic factors. Further research should explore barriers to accessing diabetes technology in non-White populations.

Postoperative day 1 versus postoperative day 5 morning cortisol for predicting an intact hypothalamic-pituitary axis: A cohort analysis.

BACKGROUND: A reliable standard for evaluating postoperative hypothalamic-pituitary-axis (HPA) function following transsphenoidal pituitary surgery (TSS) could reduce hospital stays and unnecessary prolonged steroid therapy. We retrospectively examined the predictive role of morning cortisol levels on long-term HPA function to develop an institutional protocol. Here, we report the results of this analysis, which is the first to report the predictive strength of multiple variables (i.e., timing of measurement and values of serum cortisol cutoffs) within the same cohort. METHODS: A retrospective chart review was performed in 183 patients at a single institution from 2007 to 2012. 67 patients met inclusion criteria. The predictive value of postoperative day (POD) 1 and POD 5 morning cortisol for HPA function as determined by 1 ug cosyntropin stimulation test was evaluated using standard confusion matrix calculations and receiver-operator control curve analysis. RESULTS: In our cohort, an early POD 5 serum morning cortisol ≥15 ug/dl predicted an intact HPA axis with 100% specificity, 51% sensitivity, and a positive predictive value (PPV) of 100%. A POD 1 serum cortisol ≥25 ug/dl was needed to achieve a specificity of 100% and PPV of 100% to predict an intact HPA axis with a sensitivity of 30%. A POD 1 serum cortisol ≥18 ug/dl predicted an intact HPA axis with 33.3% specificity, PPV of 90.9%, and a sensitivity of 51.3%. CONCLUSION: A POD 5 morning cortisol level ≥15 ug/dl is an excellent predictor of normal postoperative HPA function in patients undergoing TSS for pituitary adenoma.

Mechanism of Glucagon-Like Peptide 1 Improvements in Type 2 Diabetes Mellitus and Obesity.

PURPOSE OF REVIEW: The purpose of this review is to emphasize the pivotal role of glucagon-like peptide 1 (GLP-1) in tackling the parallel epidemics of obesity and type 2 diabetes (T2DM). RECENT FINDINGS: GLP-1-based therapies and in particular GLP-1 receptor agonists (GLP-1 RA) have proven to be effective in lowering blood glucose and decreasing weight. GLP-1 RA not only mitigate these significant medical burdens but also result in weight loss and weight loss independent factors that decrease cardiovascular disease (CVD) and microvascular complications of T2DM, such as diabetic nephropathy. GLP-1-based therapies are critical for a patient-centered approach in choosing appropriate pharmacotherapy for T2DM and obesity while also taking into consideration comorbidities, such as cardiovascular and chronic kidney diseases.

Diabetic Ketoacidosis Post Bariatric Surgery.

In patients with type 2 diabetes, bariatric surgery can lead to significant improvements in glycemic control and diabetes remission. We present a case of a Hispanic female with type 2 diabetes phenotype who underwent bariatric surgery and post-operatively stopped her insulin therapy due to multiple reasons, including decreased oral intake and concern for hypoglycemia. Ultimately, she developed diabetic ketoacidosis. She does not fit into the classical type 2 diabetes or type 1 diabetes definition but into the heterogeneous subgroup of diabetes called ketosis-prone diabetes.

Effect of vaccinations with recombinant fusion proteins on Ancylostoma caninum habitat selection in the canine intestine.

Laboratory dogs were vaccinated subcutaneously with 3 different recombinant fusion proteins, each precipitated with alum or calcium phosphate. The vaccinated dogs were then challenged orally with 400 third-stage infective larvae (L3) of the canine hookworm, Ancylostoma caninum. The 3 A. caninum antigens selected were Ac-TMP, an adult-specific secreted tissue inhibitor of metalloproteases; Ac-AP, an adult-specific secreted factor Xa serine protease inhibitor anticoagulant; and Ac-ARR-1, a cathepsin D-like aspartic protease. Each of the 3 groups comprised 6 male beagles (8 +/- 1 wk of age). A fourth group comprised control dogs injected with alum. All of the dogs vaccinated with Ac-TMP or Ac-APR-1 exhibited a vigorous antigen-specific antibody response, whereas only a single dog vaccinated with Ac-AP developed an antibody response. Dogs with circulating antibody responses exhibited 4.5-18% reduction in the numbers of adult hookworms recovered from the small intestines at necropsy, relative to alum-injected dogs. In contrast, there was a concomitant increase in the number of adult hookworms recovered from the colon. The increase in colonic hookworms was as high as 500%, relative to alum-injected dogs. Female adult hookworms were more likely to migrate into the colon than were males. Anti-enzyme and anti-enzyme inhibitor antibodies correlated with an alteration in adult hookworm habitat selection in the canine gastroinntestinal tract.
