Derived Time in Range and Other Metrics of Poor Glycemic Control Associated With Adverse Hospital Outcomes in Patients With Diabetes Mellitus Admitted to Non-ICU Wards at a Tertiary-Level Hospital in Colombia: A Cross-Sectional Study.

Aim: This study is aimed at assessing the prevalence of poor glycemic control using different metrics and its association with in-hospital adverse outcomes. Methods: This cross-sectional study was conducted in diabetic patients admitted to a third-level hospital in Colombia between January and July 2022. Poor glycemic control was determined using capillary glucose metrics, including mean glucose values outside the target range, derived time in range (dTIR) (100-180 mg/dL) < 70%, coefficient of variation (CV > 36%), and hypoglycemia (<70 mg/dL). Multiple regression models were adjusted for hospital outcomes based on glycemic control, as well as other sociodemographic and clinical covariates. Results: A total of 330 Hispanic patients were included. A total of 27.6% had mean glucose measurements outside the target range, 33% had a high CV, 64.8% had low dTIR, and 28.8% experienced hypoglycemia. The in-hospital mortality rate was 8.8%. An admission HbA1c level greater than 7% was linked to an increased mortality risk (p = 0.016), as well as a higher average of glucometer readings (186 mg/dL vs. 143 mg/dL; p < 0.001). A lower average of dTIR (41.0% vs. 60.0%; p < 0.001) was also associated with a higher mortality risk. Glycemic variability was correlated with an increased risk of mortality, hypoglycemia, delirium, and length of hospital stay (LOS). Conclusion: A significant number of hospitalized diabetic patients exhibit poor glycemic control, which has been found to be associated with adverse outcomes, including increased mortality. Metrics like dTIR and glycemic variability should be considered as targets for glycemic control, highlighting the need for enhanced management strategies.

Long-Term Efficacy and Safety of Sensor Augmented Insulin Pump Therapy with Low-Glucose Suspend Feature in Patients with Type 1 Diabetes.

BACKGROUND: Literature supports short-term efficacy and safety of Sensor Augmented Insulin Pump (SAP) therapy in patients with type 1 diabetes (T1D). However, no data are available showing long-term outcomes. Our study describes the long-term outcomes of SAP therapy with low-glucose suspend feature (SAP+LGS) in hypoglycemia in a Colombian population with T1D and hypoglycemia. METHODS: A cohort study was conducted with T1D patients receiving SAP+LGS therapy who initiated this therapy because of hypoglycemia at San Ignacio University Hospital diabetes center in Bogotá, Colombia. Glycated hemoglobin (A1c) was assessed at least every 6 months, severe hypoglycemia (SH) and hypoglycemia unawareness (HU) incidence yearly. Adherence to therapy was also evaluated. RESULTS: One hundred eleven patients were included in the analysis. Total daily insulin dose was reduced during follow-up (mean difference -0.22 U/kg; 95% confidence interval [CI] -0.18 to -0.26; P < 0.001). A1c levels were reduced from a baseline value of 8.8% ± 1.9% to 7.5% ± 1.0% at 5 months (mean difference -1.3%; 95% CI -1.09 to -1.50; P < 0.001) and 7.1% ± 0.8% (mean difference -1.7%; 95% CI -1.59 to -1.90; P < 0.001) at the end of follow-up (47 months on average). The incidence of SH and HU episodes decreased significantly since the first year, and this effect was maintained over time (P < 0.001). CONCLUSIONS: SAP+LGS therapy in T1D patients with hypoglycemia led to a significant and sustained decrease in A1c during long periods of follow-up, as well as a significant reduction in SH and HU. Future randomized clinical trials are desired.

Conversión de tuberculina en trabajadores del Hospital Universitario San Ignacio y asociación con características demográficas y laborales / Tuberculin skin test conversion and association with occupation and demographic characteristics in workers at San Ignacio University Hospital

Objetivos: Establecer la prevalencia de positividad, la tasa de conversión de la tuberculina en trabajadores de nuestro hospital y describir las características demográficas y laborales asociadas a esto. Materiales y Métodos Estudio observacional descriptivo en una cohorte de trabajadores del hospital a los que se les realizó la prueba de tuberculina. Se definió la positividad de la prueba de tuberculina como un resultado mayor o igual a 10 mm y la conversión como un aumento de 6 o 10 mm con respecto a la prueba inicial. Resultados Se encontró una prevalencia de 23,7 % y una incidencia de conversión de 13,6 % para el punto de corte mayor de 10 mm y 23 % para el punto de corte de 6 mm. La edad de los sujetos estuvo relacionada a conversión, mientras que no se encontró relación con la ocupación. Conclusión La probabilidad de transmisión de la tuberculosis en trabajadores del hospital es mayor al de la población general. Deben ser implementadas medidas de promoción y prevención para disminuir la transmisión e incrementar el conocimiento de la tuberculosis asociada al cuidado de la salud en los trabajadores.(AU)

Objectives To establish the prevalence of positivity and conversion rate of the tuberculin skin test in workers of our hospital, and to describe the related demographic and occupational characteristics. Materials and Methods An observational, descriptive study was conducted in a cohort of hospital workers who underwent the tuberculin skin test. The positivity of the test was defined as a result of greater than or equal to 10 mm, and conversion was defined as an increase of 6 or 10 mm with respect to the initial test. Results Prevalence of 23.7 % and incidence of conversion of 13.6 % for the major cut-off point of 10 mm, and 23 % for the lesser cut-off point of 6 mm, was found. The age of the subjects was related to the conversion, but there was no relation with occupation. Conclusions The probability of tuberculosis transmission in health-care workers is higher than in the general population. Promotion and prevention measures must be implemented to decrease the transmission and to increase awareness of tuberculosis related to occupational activities.(AU)
