Continuous glucose monitoring in insulin treated patients in non ICU settings

Q1930-936Inpatient hyperglycemia, in patients with and without a history of diabetes, is associated with increased risk of complications, mortality, and longer hospital stay in medicine and surgical patients. Bedside capillary point of care testing is widely recommended as the preferred method for glucose monitoring and for guiding glycemic management of individual patients; however, the accuracy of most handheld glucose meters is far from optimal. Recent studies in the hospital setting have reported that the use of continuous glucose monitoring (CGM) can provide real-time information about glucose concentration, direction, and rate of change over a period of several days. Because it provides glucose values every 5-10 minutes 24 hours a day, CGM may have an advantage over point of care testing with respect to reducing the incidence of severe hypoglycemia in acute care. Real-time CGM technology may facilitate glycemic control and to reduce hypoglycemia in insulin-treated patients. Recent guidelines, however, have recommended deferring the use of CGM in the adult hospital setting until further data on accuracy and safety become available. In this study, we review the advantages and disadvantages of the use of real-time CGM in the management of dysglycemia in the hospital setting

Between the rock and a hard place : Ecuador during the covid-19 pandemic

In 2020, Ecuadorian politics was not only constrained by the COVID-19 pandemic, but also stirred by political instability and an intense online electoral campaign. In this article, we outline the Ecuadorian economic, social, and political context from February 2020 to February 2021. Then, we explore the core measures and overall impacts of the COVID-19 on Ecuadorian politics. We also present the main institutional and policy changes, bearing in mind that 2020 was the last year of Lenín Moreno’s presidential term. In addition, this article examines the latest electoral reform and the main issues of the electoral campaign, as well as the key results of the national and Andean elections of February 2021

Continuous glucose monitoring versus capillary point-of-care testing for inpatient glycemic control in type 2 diabetes patients hospitalized in the general ward and treated with a basal bolus insulin regimen

Q1Artículo original325-329Background: Continuous glucose monitoring (CGM) may improve the management of patients with type 2 diabetes hospitalized in the general ward by facilitating the detection of hyper- and hypoglycemic episodes. However, the lack of data on the accuracy and safety of CGM have limited its application. Methods: A prospective pilot study was conducted including 38 patients hospitalized in the general ward with a known diagnosis of type 2 diabetes mellitus (DM) and hyperglycemic individuals without a history of DM with a blood sugar of 140-400 mg on admission treated with a basal bolus insulin regimen. Inpatient glycemic control and the incidence of hypoglycemic episodes were compared between detection by CGM of interstitial fluid for up to 6 days and point-of-care (POC) capillary blood glucose monitoring performed pre- and postprandially, before bedtime and at 3 am. Results: No differences in average daily glucose levels were observed between CGM and POC (176.2 ± 33.9 vs 176.6 ± 33.7 mg/dl, P = .828). However, CGM detected a higher number of hypoglycemic episodes than POC (55 vs 12, P < .01). Glucose measurements were clinically valid, with 91.9% of patients falling within the Clarke error grid A and B zones. Conclusions: Our preliminary results indicate that the use of CGM in type 2 patients hospitalized in the general ward provides accurate estimation of blood sugar levels and is more effective than POC for the detection of hypoglycemic episodes and asymptomatic hypoglycemia

Incidence of Cognitive Decline and Association with Changes in Sociodemographic, Lifestyle, and Health Indicators in Individuals aged 50 years and older: Prospective Cohort

Objectives: To identify the incidence of cognitive decline (CD) in an urban community-dwelling population aged 50 years and older in a 4-year follow-up period and its prospective association with sociodemographic factors, lifestyle and health conditions as well as with changes in these factors. Methods: This is a prospective cohort with a representative sample of people aged 50 years and older (n = 206) from Cambé, PR, where baseline data collection occurred in the year 2011 and the follow-up occurred in 2015. The incidence of CD was the outcome of this study, and its evaluation occurred through the Mini-Mental State Examination. Results: The incidence of CD was 13.1% over the 4 years of follow-up, and adjusted Poisson regression models (sex, age and age range) showed that this condition was prospectively associated with depression (adjusted relative risk (RR) = 3, 50, 95% CI = 1.65-7.43). When analyzing the effect of sociodemographic factor changes on CD, it was verified that the risk of CD was 2.86 times higher among the group that stopped having a companion in the 4 years of follow-up when compared to the group that maintained a companion in that same period, independent of confounding factors. Conclusion: The data suggest that the CD process begins before the age of 60 y and that aggravation is associated with potentially modifiable factors that can be approached by health services from the perspective of promotion, prevention and care

A Glycemia Risk Index (GRI) of Hypoglycemia and Hyperglycemia for Continuous Glucose Monitoring Validated by Clinician Ratings

BackgroundA composite metric for the quality of glycemia from continuous glucose monitor (CGM) tracings could be useful for assisting with basic clinical interpretation of CGM data.MethodsWe assembled a data set of 14-day CGM tracings from 225 insulin-treated adults with diabetes. Using a balanced incomplete block design, 330 clinicians who were highly experienced with CGM analysis and interpretation ranked the CGM tracings from best to worst quality of glycemia. We used principal component analysis and multiple regressions to develop a model to predict the clinician ranking based on seven standard metrics in an Ambulatory Glucose Profile: very low-glucose and low-glucose hypoglycemia; very high-glucose and high-glucose hyperglycemia; time in range; mean glucose; and coefficient of variation.ResultsThe analysis showed that clinician rankings depend on two components, one related to hypoglycemia that gives more weight to very low-glucose than to low-glucose and the other related to hyperglycemia that likewise gives greater weight to very high-glucose than to high-glucose. These two components should be calculated and displayed separately, but they can also be combined into a single Glycemia Risk Index (GRI) that corresponds closely to the clinician rankings of the overall quality of glycemia (r = 0.95). The GRI can be displayed graphically on a GRI Grid with the hypoglycemia component on the horizontal axis and the hyperglycemia component on the vertical axis. Diagonal lines divide the graph into five zones (quintiles) corresponding to the best (0th to 20th percentile) to worst (81st to 100th percentile) overall quality of glycemia. The GRI Grid enables users to track sequential changes within an individual over time and compare groups of individuals.ConclusionThe GRI is a single-number summary of the quality of glycemia. Its hypoglycemia and hyperglycemia components provide actionable scores and a graphical display (the GRI Grid) that can be used by clinicians and researchers to determine the glycemic effects of prescribed and investigational treatments

Design and baseline characteristics of the finerenone in reducing cardiovascular mortality and morbidity in diabetic kidney disease trial

Background: Among people with diabetes, those with kidney disease have exceptionally high rates of cardiovascular (CV) morbidity and mortality and progression of their underlying kidney disease. Finerenone is a novel, nonsteroidal, selective mineralocorticoid receptor antagonist that has shown to reduce albuminuria in type 2 diabetes (T2D) patients with chronic kidney disease (CKD) while revealing only a low risk of hyperkalemia. However, the effect of finerenone on CV and renal outcomes has not yet been investigated in long-term trials. Patients and Methods: The Finerenone in Reducing CV Mortality and Morbidity in Diabetic Kidney Disease (FIGARO-DKD) trial aims to assess the efficacy and safety of finerenone compared to placebo at reducing clinically important CV and renal outcomes in T2D patients with CKD. FIGARO-DKD is a randomized, double-blind, placebo-controlled, parallel-group, event-driven trial running in 47 countries with an expected duration of approximately 6 years. FIGARO-DKD randomized 7,437 patients with an estimated glomerular filtration rate >= 25 mL/min/1.73 m(2) and albuminuria (urinary albumin-to-creatinine ratio >= 30 to <= 5,000 mg/g). The study has at least 90% power to detect a 20% reduction in the risk of the primary outcome (overall two-sided significance level alpha = 0.05), the composite of time to first occurrence of CV death, nonfatal myocardial infarction, nonfatal stroke, or hospitalization for heart failure. Conclusions: FIGARO-DKD will determine whether an optimally treated cohort of T2D patients with CKD at high risk of CV and renal events will experience cardiorenal benefits with the addition of finerenone to their treatment regimen. Trial Registration: EudraCT number: 2015-000950-39; ClinicalTrials.gov identifier: NCT02545049

Impairment of mitochondrial bioenergetics and permeability transition induction caused by major long-chain fatty acids accumulating in VLCAD deficiency in skeletal muscle as potential pathomechanisms of myopathy

cis-5-Tetradecenoic (cis-5) and myristic (Myr) acids predominantly accumulate in patients affected by very long-chain acyl-CoA dehydrogenase (VLCAD) deficiency. They commonly manifest myopathy with muscular pain and rhabdomyolysis, whose underlying mechanisms are poorly known. Thus, in the present study we investigated the effects of cis-5 and Myr on mitochondrial bioenergetics and Ca2+ homeostasis in rat skeletal muscle. cis-5 and Myr decreased ADP-stimulated (state 3) and CCCP-stimulated (uncoupled) respiration, especially when mitochondria were supported by NADH-linked as compared to FADH(2)-linked substrates. In contrast, these fatty acids increased resting respiration (state 4). Similar effects were observed in skeletal muscle fibers therefore validating the data obtained with isolated mitochondria. Furthermore, cis-S and Myr markedly decreased mitochondrial membrane potential and Ca2+ retention capacity that were avoided by cyclosporin A plus ADP and ruthenium red, indicating that cis-5 and Myr induce mitochondrial permeability transition (MPT). Finally, docosanoic acid did not disturb mitochondria] homeostasis, indicating selective effects for Myr and cis-5. Taken together, our findings indicate that major long-chain fatty acids accumulating in VLCAD deficiency behave as metabolic inhibitors, uncouplers of oxidative phosphorylation and MPT inducers. It is presumed that these pathomechanisms contribute to the muscular symptoms and rhabdomyolysis observed in patients affected by VLCAD deficiency62CONSELHO NACIONAL DE DESENVOLVIMENTO CIENTÍFICO E TECNOLÓGICO - CNPQFUNDAÇÃO DE AMPARO À PESQUISA DO ESTADO DE SÃO PAULO - FAPESPFUNDAÇÃO DE AMPARO À PESQUISA DO ESTADO DO RIO GRANDE DO SUL - FAPERGS425914/2016-017/17728-82266-2551/14-
