RESUMO

Objective The COVID-19 pandemic has imposed a great burden on healthcare workers worldwide. The aim of the present study was to assess sleep quality, insomnia, and perceived stress in healthcare workers of a high complexity hospital located in Bogota, Colombia. Methods Cross-sectional study in which 1,155 healthcare workers at the Hospital Universitario San Ignacio in Bogotá, Colombia were included, between September and October 2020. Using an online-based survey, self-reported variables were assessed including demographics, Pittsburgh Sleep Quality Index (PSQI), Insomnia Severity Index (ISI), and 10 item Perceived Stress Scale (PSS-10). Associations between these variables were evaluated. Results Fifty percent of the respondents were between 31 and 45 years old, and 76 percent were women. Most of the surveyed were the nursing staff. Poor sleep quality, insomnia, and high perceived stress was found in 74.9, 12.4, and 13.2%, respectively. Poor sleep quality was predominantly found in females, in the 31 to 45 years old group and in married personnel. Also, poor sleep quality was found in relation to a moderate to high perceived risk of COVID-19 infection by the family of the workers surveyed. Discussion Poor sleep quality, moderate rates of insomnia, and perceived stress were found among healthcare workers committed to COVID-19 infected patients in Colombia. The identification of workers at greater risk and the implementation of targeted interventions are called upon as the results.

RESUMO

INTRODUCTION: There are data capture devices that attach to the FreeStyle Libre sensor and convert its communication from NFC (Near-field communication) to Bluetooth technology, generating real-time continuous glucose monitoring. The accuracy of hypoglycemia measurements displayed by smartphone apps using this device has not been established. METHODS: Study of diagnostic tests. Numerical accuracy was evaluated, utilizing the absolute difference with respect to capillary glucometry (ISO 15197:2015 standard) and clinical accuracy, using the Clarke and Parkes (Consensus) error grids, for glucose measurements less than 70mg/dL performed with the FreeStyle Libre system and with the digital estimation xDrip+ app, in diabetic patients managed with insulin therapy. RESULTS: Twenty-seven patients were included (TIR 73.4%, TBR70 5.6%), who contributed 83 hypoglycemic events. Numerical accuracy was adequate in similar proportions with the FreeStyle Libre system compared to the xDrip+ app (81.92% vs. 68.67%, p=0.0630). The clinical accuracy evaluation showed that 92.8% of the measurements for xDrip+ and 98.8% for FreeStyle libre met the criteria according to the Parkes (Consensus) grid (p=0.0535); and 79.5% and 91.6% of the measurements met the criteria according to the Clarke grid (p=0.0273), being higher with FreeStyle libre. CONCLUSIONS: The use of the NFC-Bluetooth transmitter (Miao-Miao) associated with the xDrip+ app does not improve numerical or clinical accuracy for detecting hypoglycemic events in diabetic patients managed with insulin therapy, compared to the FreeStyle Libre device.

RESUMO

OBJECTIVE: To determine the frequency of sleep problems in low-income, urban pediatric populations in cities at different altitudes in Colombia. METHODS: A descriptive, cross-sectional population-based observational study was conducted in children aged between 2 and 12 years in the low income, urban areas of three cities in Colombia (Santa Marta, Bucaramanga, and Bogotá) located at 15, 959, and 2640 m above sea level, respectively. Sociodemographic data were collected, and the Spanish version of the Pediatric Sleep Questionnaire was used. RESULTS: 1989 children were surveyed, distributed as follows: Santa Marta (32.0%), Bucaramanga (33.4%), and Bogotá (34.6%). The overall prevalence of sleep problems was 39.0%. Children from Santa Marta had the highest frequency of parasomnias (58.0%); those from Bucaramanga had the highest frequency of attention deficit symptoms (4.0%) and apneic pauses witnessed by parents or caregivers (5.7%). Finally, Bogotá, the only high-altitude location, had the highest frequency of sleep disordered breathing (17.2%). CONCLUSIONS: The study found a high frequency of sleep problems in the pediatric population, especially at higher altitudes when compared to lower altitude settings. Sleep disorders warrant early detection and timely therapeutic intervention.

RESUMO

OBJECTIVES: Polysomnogram is the gold standard for the diagnosis of sleep-disordered breathing (SDB); a sensitive and specific alternative strategy would be ideal, due to its low availability, and screening patients at high risk of OSA is very important. This study aimed to determine the operating characteristics of screening tests in patients with and without cardiovascular disease (CVD). MATERIAL AND METHODS: Epworth sleepiness scale (ESS), Berlin, STOP-bang and Pittsburgh sleep quality index (PSQI) were applied in adults with and without cardiovascular disease in three Colombian cities, as well as anthropometric measurements and a polysomnogram. Operating characteristics were calculated for each test and the best cut-off values in patients with and without CVD were obtained. RESULTS: 964 patients (median age: 58), 662 with and 302 without CVD were included. The prevalence for SDB (AHI =5) were 43.4 % (OSA), 16.2% (central apnea), and 12.4 % (other). In patients without CVD, the highest sensitivity for OSA and central apnea was for PSQI (80-85%). The highest specificity was for STOP-bang (68%) and Berlin (78.6%). In CVD the best sensitivity was for PSQI (81.9%) followed by Berlin (71.9%) and the best specificity for STOP-bang (82.1%). No isolated questionnaire showed good diagnostic performance (AUC=0.6) and the cut-off values had no variations except for ESS. CONCLUSION: Screening tests showed low operating characteristics for the diagnosis to SDB, but better performance in patients with CVD. They are not recommended as the only diagnostic test, but they can be useful to guide the initial diagnostic process.

RESUMO

BACKGROUND AND AIMS: The literature has supported the efficacy and safety of insulin pump therapy in young adults diagnosed with type 1 diabetes (DM1). However, there is limited evidence in older adults with DM1 and DM2. METHODS: A retrospective cohort study was conducted in patients ≥60 years-old with DM1 and DM2, who started Sensor Augmented Insulin Pump therapy with low-glucose suspend feature (SAP + LGS) at Hospital Universitario San Ignacio diabetes center in Bogotá, Colombia. Patients were evaluated between 2009 and 2019 and were treated with Paradigm VEO or Medtronic MiniMed 640 insulin pumps and continuous glucose monitoring system. Glycated hemoglobin (A1c), severe hypoglycemia and hypoglycemia unawareness were assessed at least every 3 months, and hospitalizations and ketoacidosis episodes incidence were assessed yearly. RESULTS: 36 patients were analyzed, (67.36 ± 4.88 years-old) (body mass index 25.48 ± 4.61 kg/m2). The most common indications for starting SAP + LGS were hypoglycemia (58.3%), high glycemic variability (25.0%) and poor metabolic control (16.7%). 26 patients used VEO (72.2%) whereas 27.8% started 640 insulin pump. Data from 32 participants showed A1c decreased from 8.57 ± 1.73% to 7.42 ± 0.96 after a year of therapy (Mean difference -1.15%, p < 0.05); 28.12% reached A1c levels <7% and 42.85% < 7.5%. There was a significant decrease in the proportion of patients with at least one severe hypoglycemia (56.7 vs 3.3%), one or more hospitalizations (20 vs 3.3%), and hypoglycemia unawareness after the first year of follow-up (p < 0.05). CONCLUSIONS: These results suggest that SAP + LGS is safe and effective in people 60 years or older after one year of therapy. Future randomized clinical trials are needed in the elderly.

RESUMO

Aims: The aim of the study was to assess the incidence of sleep-related breathing disorders (SRBD) in children with Down Syndrome (DS) living at high altitude. Methods: A retrospective descriptive study was conducted on 53 children with DS who underwent polysomnography (PSG) at San Ignacio University Hospital (2640 m/8660 ft above sea level) from 2009 to 2016. Data were extracted from official PSG reports and analyzed using measures of central tendency and dispersion, frequency calculation, ranges, and confidence intervals. Associations were examined using t-test, chi-square test, and analysis of variance test. Results: Obstructive sleep apnea (OSA) was present in 90.5% of children. Central sleep apnea was evident in 11.3%. Periodic breathing was seen in 15.1% of patients. Snoring was able to predict OSA with a sensitivity of 61.7%, a specificity of 100%, and negative predictive value of 25%. Conclusion: Children with DS who live at high altitude have a high incidence of SRBD. Our findings show a higher incidence of SRBD than previously reported in the population with DS. Furthermore, snoring was not sensitive enough to predict OSA. This high risk of SRBD may increase the risk of other comorbid conditions seen in the population with DS. Our results support the need for routine PSG screening independent of symptoms such as snoring status.

RESUMO

BACKGROUND: Pregnancy in women with type 1 diabetes (T1D) is associated with increased risk of maternal complications and neonatal morbidity and mortality. Optimizing glycemic control improves these outcomes. OBJECTIVE: To describe the experience of using sensor-augmented insulin pump therapy (SAPT) and SAPT + low-glucose suspension (LGS) on pregnant women with T1D, including neonatal and maternal outcomes. METHODS: A prospective observational study was conducted in women with T1D who started SAPT and SAPT + LGS before or during pregnancy at the San Ignacio University Hospital Diabetes Center in Bogotá, Colombia. The main indication was severe hypoglycemia (SH) and poor glycemic control. Glycated hemoglobin (A1c), hypoglycemia, and maternal and fetal outcomes were assessed. RESULTS: Thirty-four pregnant women with T1D on SAPT and SAPT + LGS were included. Sixteen patients started therapy during pregnancy at a mean gestational age of 17.6 ± 8.3 weeks. Mean preconceptional A1c was 8.24% ± 2.02%. Absolute reduction of A1c level from prepregnancy to third trimester was -1.63% (P < 0.0001), with a significant clinical and statistical reduction in both groups, women who initiated SAPT before or during pregnancy. 52.9% of patients in second trimester and 66.6% in third trimester achieved A1c <6.5%, respectively. 91.1% underwent cesarean section. The main reasons were iterative cesarean (30%), fetal distress (20%), and preeclampsia (16%). The median gestational age at delivery was 37 weeks and 15 pregnancies resulted in preterm delivery. There was neither maternal-fetal mortality nor severe hypoglycemic episodes. Two patients had diabetic ketoacidosis. CONCLUSIONS: In pregnant patients with T1D and high risk of hypoglycemia, SAPT and SAPT + LGS should be considered as a therapeutic alternative for A1c reduction with a low risk of SH. However, additional studies are required to evaluate the efficacy and safety of this therapy during pregnancy.

RESUMO

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.
