Background/UNASSIGNED:Patients on maintenance hemodialysis are particularly vulnerable to infection and hospitalization from severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Due to immunocompromised patients and the clustering that occurs in outpatient dialysis units, the seroprevalence of COVID-19 antibodies in this population is unknown and has significant implications for public health. Also, little is known about their risk factors for hospitalization. Methods/UNASSIGNED:nasopharyngeal, real-time, reverse-transcriptase PCR (RT-PCR); SARS-CoV-2 IgG seropositivity; hospitalization; and mortality. Results/UNASSIGNED:<0.001) compared with those who tested negative. Higher positivity rates were also observed among those who took taxis and ambulettes to and from dialysis, compared with those who used personal transportation. Antibodies were detected in all of the patients with a positive PCR result who underwent serologic testing. Of those that were seropositive, 32% were asymptomatic. The hospitalization rate on the basis of either antibody or PCR positivity was 35%, with a hospital mortality rate of 33%. Aside from COPD, no other variables were more prevalent in patients who were hospitalized. Conclusions/UNASSIGNED:We observed significant differences in rates of COVID-19 infection within three outpatient dialysis units, with universal seroconversion. Among patients with ESKD, rates of asymptomatic infection appear to be high, as do hospitalization and mortality rates.

BACKGROUND/UNASSIGNED:Continuous subcutaneous insulin infusion (CSII) is a common diabetes treatment modality. Glycemic outcomes of patients using CSII in the first 24 hours of hospitalization have not been well studied. This timeframe is of particular importance because insulin pump settings are programmed to achieve tight outpatient glycemic targets which could result in hypoglycemia when patients are hospitalized. METHODS/UNASSIGNED:This retrospective cohort study evaluated 216 hospitalized adult patients using CSII and 216 age-matched controls treated with multiple daily injections (MDI) of insulin. Patients using CSII did not make changes to pump settings in the first 24 hours of admission. Blood glucose (BG) values within the first 24 hours of admission were collected. The primary outcome was frequency of hypoglycemia (BG < 70 mg/dL). Secondary outcomes were frequency of severe hypoglycemia (BG < 40 mg/dL) and hyperglycemia (BG ≥ 180 mg/dL). RESULTS/UNASSIGNED: = 0.06). CONCLUSIONS/UNASSIGNED:Patients using CSII experienced fewer events of both hypoglycemia and hyperglycemia in the first 24 hours of hospital admission than those treated with MDI. Our study demonstrates that CSII use is safe and effective for the treatment of diabetes within the first 24 hours of hospital admission.

Premature infants are at high risk for heat loss. Infants undergoing surgical procedures outside of the neonatal intensive care unit have an increased risk of hypothermia. Hypothermia can lead to delayed recovery, hypoglycemia, metabolic acidosis, sepsis, and emotional stress for the parents. We aimed to reduce the incidence of hypothermia for infants undergoing surgical procedures from a baseline of 44.4% to less than 25% over 3 years (2016-2018) with the utilization of a checklist and education.

Objective: To evaluate the safety and efficacy of GlucoStabilizer software intravenous insulin (IV) dosing in comparison to American Diabetes Association (ADA) protocol-directed provider-guided insulin dose adjustment (PGIA). Methods: GlucoStabilizer calculates the dose of IV insulin required to reach a prescribed target glucose range. GlucoStabilizer has not been fully studied in DKA. This retrospective study compared outcomes in patients with DKA before and after implementation of GlucoStabilizer. Insulin doses were administered based on GlucoStabilizer calculations or PGIA. The analysis evaluated before-after changes in amount of insulin used, time to target, hypoglycemia or hypokalemia events, and time to DKA resolution. Results: We studied 77 patients with insulin doses calculated by GlucoStabilizer and 69 patients with PGIA dosing. GlucoStabilizer was superior to PGIA. Patients treated with GlucoStabilizer-calculated doses did not experience hypoglycemia (N= 0 vs. N= 10; p<0.001). The 10 unique PGIA patients had a total of 18 episodes with 17 between 55 to 69 mg/dL; 1 <54 mg/dL, and no episodes <40 mg/dL. The GlucoStabilizer group required less insulin to reach DKA resolution (59.2 vs. 101.2 units; p<0.001). Time to glycemic target and DKA resolution were similar (6.7 vs. 4.6 hours; p= 0.132) and (9.8 vs. 9.9 hours; p= 0.803), respectively. No difference in incidence of hypokalemia was seen (N= 9 vs. N= 11; p= 0.48).
