Abstract Introduction: The control and evaluation of glycemic levels in critically ill patients is a challenge and a responsibility of the nursing team; therefore, determining the consequences of this during hospitalization is key to demonstrate the importance of timely management. Objective: To determine the relationship between unstable glycemia (hyperglycemia and hypoglycemia), hospital length of stay, and the hospitalization outcome of patients in an Intensive Care Unit (ICU). Methods: A prospective cohort study conducted with 62 critically ill patients by convenience sampling between March and July 2017. Daily blood samples were collected to measure glycemia. The correlation of unstable glycemia with the hospital length of stay and the hospitalization outcome was assessed using Pearson's chi-square. A p-value <0.05 was considered significant. Results: Among the 62 patients, 50% were male and 50% were female. The mean age was 63.3 years (±21.4 years). The incidence of unstable glycemia was 45.2% and was associated with a longer ICU stay (p<0.001) and a progression to death as a hospitalization outcome (p=0.03). Conclusion: Among critically ill patients, unstable glycemia was associated with an extended hospital length of stay and a progression to death, emphasizing the importance of nursing intervention to prevent its occurrence.

Association between hyperglycemia and post-exodontia complications in patients with type ii diabetes mellitus: a scoping review / Asociación entre hiperglucemia y complicaciones post-exodoncia en pacientes con diabetes mellitus tipo ii: scoping review

Introduction: Diabetes mellitus (DM) is a prevalent chronic metabolic disorder worldwide, with Type II DM (T2DM) emerging as the most widespread variant. In Chile, approximately 11% of adults aged 20 to 79 suffer from this condition. Given its high prevalence, dental surgeons should be trained to evaluate risk factors, particularly the potential complications linked to tooth extraction in individuals with T2DM. Objetive: To describe the available scientific evidence on post-exodontia complications associated with hyperglycemia in patients with Type II diabetes mellitus. Materials and Methods: An exploratory systematic review was conducted following the PRISMA-ScR extension protocols using the databases PubMed, EBSCO, Scopus and the Cochrane Library. The search employed the following algorithms: (("Diabetic patient complications" AND "Dental extractions")), (("Diabetes" AND "tooth extraction")), (("Glycemia" AND "Tooth extraction complications"), (("Blood glucose" AND "Tooth extractions"), (("Dental extraction sockets" AND "Diabetics"). Results: Out of a total of 973 articles, 25 were included for this review. Six relevance criteria were considered, revealing safety parameters for conducting extractions in patients with T2DM, with capillary blood glucose levels not exceeding 200 mg/dL for elective extractions and 240 mg/dL for emergency extractions. Conclusions: There is limited evidence correlating threshold values of hyperglycemia with post-extraction complications in patients with T2DM. Most authors agree that the primary concern is not T2DM itself, but hyperglycemia. Furthermore, there is minimal consistency in the recommended care protocols for these patients.

Introducción: La diabetes mellitus (DM) es un trastorno metabólico crónico. A nivel mundial, la DM tipo II (DM2) resulta ser la más frecuente. En Chile, un 11% de la población adulta entre los 20 y 79 años la padece. Su alta prevalencia, requiere de un cirujano dentista preparado para valorar los factores de riesgo, como las posibles complicaciones asociadas a la extracción dental en estos pacientes. Objetivo: Describir la evidencia científica disponible sobre complicaciones post-exodoncia asociadas a hiperglicemia en pacientes con diabetes mellitus tipo II. Materiales y Métodos: Se realizó una revisión sistemática exploratoria bajo los protocolos de extensión PRISMA-ScR utilizando las bases de datos, PubMed, EBSCO, Scopus y Cochrane Library con los algoritmos de búsqueda (("Diabetic patient complications" AND "Dental extractions")), (("Diabetes"AND "Tooth extraction")), (("Glycemia" AND "tooth extraction complications")), (("Blood glucose" AND "Tooth extractions")), (("Dental extraction sockets"AND "Diabetics")). Resultado: De un total de 973 artículos se incluyeron 25 artículos para esta revisión. Se consideraron 6 criterios de pertinencia, los cuales mostraron parámetros de seguridad para realizar exodoncias, en pacientes con DM2, con la glucemia capilar no mayor a 200mg/dl en caso de ser electiva y 240 mg/dl en exodoncia de urgencias. Conclusión: Existe poca evidencia que correlacione valores absolutos de hiperglucemia y complicaciones post exodoncia en pacientes con DM2. La mayoría de los autores concuerda en que el problema no es la DM2, sino la hiperglucemia. Existe poca uniformidad en los protocolos de atención recomendados para estos pacientes.

Phenotypic characteristics and differentiation potential of gingival mesenchymal stem cells in hyperglycemia ­ an ex vivo exploratory study / Características fenotípicas y potencial de diferenciación de las células madre mesenquimales gingivales en la hiperglucemia: un estudio exploratorio ex vivo

Background: The therapeutic use of gingival mesenchymal stem cells (GMSCs) as autologous cells may pose the challenge of alterations inflicted by the hyperglycemic environment. Objective: This study aims to assess the effects of hyperglycemia on the characteristics of GMSCs in diabetics. Materials and Methods: 10 patients who consented and fulfilled the criteria for inclusion and exclusion were recruited and categorized as test (HbA1c > 6.5) and control (HbA1c < 6.0). Gingival explants were obtained from gingival collar of teeth, washed, digested and cultured. The cells were subjected to microscopic observation to assess phenotype characteristics, and flow cytometry and qRT-PCR to assess differentiation potential. Stem cell markers CD90, CD73, CD105, CD34, CD45, HLA DR & HLA ABC, osteogenic differentiation markers RUNX2 & OCN, adipogenic differentiation markers PPARG2 & FABP4 and chondrogenic differentiation markers SOX9 & AGCN were evaluated. Results: Microscopic appearance of spindle shaped cells was found to be comparable in both groups. Flow cytometry results demonstrated comparable expressions with both groups, samples being positive for CD90, CD73, CD105, HLA ABC and negative for CD34, CD45 & HLA DR. There were variations in the expression of markers when assessed for differentiation potentials. Conclusions: The hyperglycemic environment did not manifest any changes in the phenotypic characteristics of GMSCs among diabetics. However, the expression of certain differentiation markers was significantly altered in the diabetic test population included. Further research is being conducted to understand the GMSCs in a hyperglycemic environment with an aim to develop strategies to optimize its clinical implications. Keywords: Gingiva; Mesenchymal stem cells; Diabetes mellitus; Cell Differentiation; Hyperglycemia; Flow cytometry.

The association of hyperglycemia with the development of infectious complications in adult Filipino patients with acute lymphoblastic leukemia

Abstract Introduction Hyperglycemia occurs in Acute Lymphoblastic Leukemia (ALL) due to chemotherapeutic agents and may be stress-induced. Given the potential impact of hyperglycemia on the clinical outcomes of ALL patients, we sought to determine the association of hyperglycemia with the development of infectious complications. Methods This is a retrospective cohort involving adult Filipino ALL patients admitted at a tertiary referral center. Patients were stratified according to blood glucose levels and infections were classified into microbiologically and clinically defined infections. Logistic regression was performed to determine whether hyperglycemia was associated with the development of infectious complications. Results Of the 174 patients admitted for ALL, only 76 patients (44%) underwent blood glucose monitoring and were thus included in this study. Hyperglycemia was observed in 64 patients (84.21%). Infectious complications were seen in 56 patients (73.68%), of whom 37 patients (48.68%) had microbiologically defined infections and 19 (25%) had clinically defined infections. The respiratory tract was the most common site of infection and gram-negative bacteria were the predominant isolates. Hyperglycemia significantly increased the likelihood of infectious complications, particularly at blood glucose levels ≥ 200 mg/dL. Conclusion Hyperglycemia is associated with an increased likelihood of infectious complications in Filipino ALL patients. With sepsis being one of the main causes of mortality in this population, our study provides compelling evidence for us to consider routine blood glucose monitoring in order to manage and potentially decrease the occurrence of infections in these patients.

Predictive value of stress-induced hyperglycemia on 28 d risk of all-cause death in intensive care patients / 北京大学学报(医学版)

OBJECTIVE@#To investigate the relationship between stress glucose elevation and the risk of 28 d all-cause mortality in intensive care unit (ICU) patients, and to compare the predictive efficacy of different stress glucose elevation indicators.@*METHODS@#ICU patients who met the inclusion and exclusion criteria in the Medical Information Mart for Intensive Care Ⅳ (MIMIC-Ⅳ) database were used as the study subjects, and the stress glucose elevation indicators were divided into Q1 (0-25%), Q2 (>25%- 75%), and Q3 (>75%-100%) groups, with whether death occurred in the ICU and the duration of treatment in the ICU as outcome variables, and demographic characteristics, laboratory indicators, and comorbidities as covariates, Cox regression and restricted cubic splines were used to explore the association between stress glucose elevation and the risk of 28 d all-cause death in ICU patients; and subject work characteristics [receiver operating characteristic (ROC) and the area under curve (AUC)] were used to evaluate the predictive efficacy of different stress glucose elevation indicators, The stress hyperglycemia indexes included: stress hyperglycemia ratio (SHR1, SHR2), glucose gap (GG); and the stress hyperglycemia index was further incorporated into the Oxford acute severity of illness score (OASIS) to investigate the predictive efficacy of the improved scores: the AUC was used to assess the score discrimination, and the larger the AUC indicated, the better score discrimination. The Brier score was used to evaluate the calibration of the score, and a smaller Brier score indicated a better calibration of the score.@*RESULTS@#A total of 5 249 ICU patients were included, of whom 7.56% occurred in ICU death. Cox regression analysis after adjusting for confounders showed that the HR (95%CI) for 28 d all-cause mortality in the ICU patients was 1.545 (1.077-2.217), 1.602 (1.142-2.249) and 1.442 (1.001-2.061) for the highest group Q3 compared with the lowest group Q1 for SHR1, SHR2 and GG, respectively, and The risk of death in the ICU patients increased progressively with increasing indicators of stressful blood glucose elevation (Ptrend < 0.05). Restricted cubic spline analysis showed a linear relationship between SHR and the 28 d all-cause mortality risk (P>0.05). the AUC of SHR2 and GG was significantly higher than that of SHR1: AUCSHR2=0.691 (95%CI: 0.661-0.720), AUCGG=0.685 (95%CI: 0.655-0.714), and AUCSHR1=0.680 (95%CI: 0.650-0.709), P < 0.05. The inclusion of SHR2 in the OASIS scores significantly improved the discrimination and calibration of the scores: AUCOASIS=0.820 (95%CI: 0.791-0.848), AUCOASIS+SHR2=0.832 (95%CI: 0.804-0.859), P < 0.05; Brier scoreOASIS=0.071, Brier scoreOASIS+SHR2=0.069.@*CONCLUSION@#Stressful glucose elevation is strongly associated with 28 d all-cause mortality risk in ICU patients and may inform clinical management and decision making in intensive care patients.

Objectives@#This research aims to investigate whether there is an association between acute hyperglycemia and diabetes mellitus and the amount of circulating platelet-derived microparticles (PDMPs) during acute myocardial infarction (AMI) initial episode.@*Methodology@#This was a cross-sectional study. Subjects were AMI patients underwent hospitalization. Demography and clinical data were obtained from hospital records. Diabetes mellitus was defined from history of disease, antidiabetic use and/or level of HbA1C ≥6.5%. Levels of HbA1c, admission random and fasting blood glucose levels were measured in hospital laboratory. The PDMPs was measured by flow-cytometry method, by tagging with CD-41 FITC and CD-62 PE markers and threshold size of <1 µm, from venous blood. The circulating PDMPs amount was compared according to glucometabolic state, namely acute hyperglycemia (admission random glucose ≥200 mg/dL and fasting glucose ≥140 mg/dL) and diabetes mellitus. The comparative analysis between group was conducted with Student T tests or Mann-Whitney tests, where applicable.@*Results@#A total of 108 subjects were included and their data analyzed. Circulating PDMPs amount was significantly lower in subjects with admission random glucose ≥200 mg/dL as compared to those with below level (median (interquartile range (IQR)): 2,710.0 (718.0-8,167.0) count/mL vs. 4,452.0 (2,128.5-14,499.8) count/mL, p=0.05) and in subjects with fasting glucose ≥140 mg/dL as compared to those with below level (median (IQR): 2,382.0 (779.0-6,619.0) count/mL vs. 5,972.0 (2,345.7-14,781.3) count/mL, p=0.006). Circulating PDMPs amount was also significantly lower in diabetes mellitus as compared to non diabetic (median (IQR): 2,655.0 (840.0-5,821.0) count/mL vs. 4,562.0 (2,128.5-15,055.8) count/mL; p=0.007).@*Conclusion@#Acute hyperglycemia and diabetes mellitus significantly associated with lower amount of circulating PDMPs during the initial episode of AMI.

Predictors of poor glycemic control and increased glucose variability among admitted moderate to critical COVID-19 patients with type 2 diabetes mellitus: A single center cross-sectional study / Journal of the ASEAN Federation of Endocrine Societies

Objectives@#COVID-19 exacerbates the long-standing, low-grade chronic inflammation observed in diabetes leading to heightened insulin resistance and hyperglycemia. Mortality increases with hyperglycemia and poor glycemic variability, hence, this study aims to identify the predictors associated with poor glycemic control and increased glucose variability among patients with COVID-19 and Type 2 Diabetes Mellitus (T2DM).@*Methodology@#A retrospective chart review of 109 patients with moderate to severe COVID-19 and T2DM admitted from March 2020 to June 2021 was done. Logistic regression was done to determine predictors for hyperglycemia and poor variability.@*Results@#Of the 109 patients, 78% had hyperglycemia and poor variability and 22% had no poor outcomes. Chronic kidney disease (eOR 2.83, CI [1.07-7.46], p=0.035) was associated with increased glycemic variability. In contrast, increasing eGFR level (eOR 0.97, CI [0.96-0.99], p=0.004) was associated with less likelihood of increased variability. Hs-CRP (eOR 1.01, CI [1.00-1.01], p=0.011), HbA1c (eOR 1.86, CI [1.23-2.82], p=0.003), severe COVID-19 (eOR 8.91, CI [1.77-44.94], p=0.008) and critical COVID-19 (eOR 4.42, CI [1.65-11.75], p=0.003) were associated with hyperglycemia. Steroid use (eOR 71.17, CI [8.53-593.54], p<0.001) showed the strongest association with hyperglycemia.@*Conclusion@#Potential clinical, laboratory and inflammatory profiles were identified as predictors for poor glycemic control and variability outcomes. HbA1c, hs-CRP, and COVID-19 severity are predictors of hyperglycemia. Likewise, chronic kidney disease is a predictor of increased glycemic variability.

Stress hyperglycemia and nutritional therapy / 中华危重病急救医学

Stress induced hyperglycemia is the body's protect response against strong (patho-physiological and/or psychological) stress, sometimes the blood glucose level is too high due to out of the body's adjustment. Renal glucose threshold (about 9 mmol/L) is a window of glucose leak from capillary to interstitial tissue. It is important to keep blood glucose level < 9 mmol/L, for reducing vascular sclerosis as well as organs hypoperfusion, meanwhile pay attention to preventing more dangerous hypoglycemia. Glucose, as the main energy substrate, should be daily supply and its metabolism should be monitored. We used to talk "nutritional support". Support is conform the physiological ability of host, but therapy is to coordinate and change pathophysiology. So, nutritional support is not equal to nutritional therapy. For critical ill patients, we need to emphasize "nutritional therapy", i.e, do not give nutritional treatment without metabolic monitoring, make up for deficiencies and avoid metabolites overloading, rational adjustment to protect and coordinate organs function.

Diacylated anthocyanins from purple sweet potato (Ipomoeabatatas L.) attenuate hyperglycemia and hyperuricemia in mice induced by a high-fructose/high-fat diet / 浙江大学学报（英文版）（B辑：生物医学和生物技术）

Studies have shown that targeting xanthine oxidase (XO) can be a feasible treatment for fructose-induced hyperuricemia and hyperglycemia. This study aimed to evaluate the dual regulatory effects and molecular mechanisms of diacylated anthocyanins from purple sweet potato (diacylated AF-PSPs) on hyperglycemia and hyperuricemia induced by a high-fructose/high-fat diet. The body weight, organ index, serum biochemical indexes, and liver antioxidant indexes of mice were measured, and the kidneys were observed in pathological sections. The relative expression levels of messenger RNAs (mRNAs) of fructose metabolism pathway enzymes in kidney were detected by fluorescent real-time quantitative polymerase chain (qPCR) reaction technique, and the expression of renal transporter protein and inflammatory factor pathway protein was determined by immunohistochemistry (IHC) technique. Results showed that diacylated AF-PSPs alleviated hyperuricemia in mice, and that this effect might be related to the regulation of liver XO activity, lipid accumulation, and relevant renal transporters. Diacylated AF-PSPs reduced body weight and relieved lipid metabolism disorder, liver lipid accumulation, and liver oxidative stress, thereby enhancing insulin utilization and sensitivity, lowering blood sugar, and reducing hyperglycemia in mice. Also, diacylated AF-PSPs restored mRNA levels related to renal fructose metabolism, and reduced kidney injury and inflammation. This study provided experimental evidence for the mechanisms of dual regulation of blood glucose and uric acid (UA) by diacylated AF-PSPs and their utilization as functional foods in the management of metabolic syndrome.

A review of patent literature on the regulation of glucose metabolism by six phytocompounds in the management of diabetes mellitus and its complications / 中西医结合学报

Diabetes mellitus is a chronic disease, typified by hyperglycemia resulting from failures in complex multifactorial metabolic functions, that requires life-long medication. Prolonged uncontrolled hyperglycemia leads to micro- and macro-vascular complications. Although antidiabetic drugs are prescribed as the first-line treatment, many of them lose efficacy over time or have severe side effects. There is a lack of in-depth study on the patents filed concerning the use of natural compounds to manage diabetes. Thus, this patent analysis provides a comprehensive report on the antidiabetic therapeutic activity of 6 phytocompounds when taken alone or in combinations. Four patent databases were searched, and 17,649 patents filed between 2001 and 2021 were retrieved. Of these, 139 patents for antidiabetic therapeutic aids that included berberine, curcumin, gingerol, gymnemic acid, gymnemagenin and mangiferin were analyzed. The results showed that these compounds alone or in combinations, targeting acetyl-coenzyme A carboxylase 2, serine/threonine protein kinase, α-amylase, α-glucosidase, lipooxygenase, phosphorylase, peroxisome proliferator-activated receptor-γ (PPARγ), protein tyrosine phosphatase 1B, PPARγ co-activator-1α, phosphoinositide 3-kinase and protein phosphatase 1 regulatory subunit 3C, could regulate glucose metabolism which are validated by pharmacological rationale. Synergism, or combination therapy, including different phytocompounds and plant extracts, has been studied extensively and found effective, whereas the efficacy of commercial drugs in combination with phytocompounds has not been studied in detail. Curcumin, gymnemic acid and mangiferin were found to be effective against diabetes-related complications. Please cite this article as: DasNandy A, Virge R, Hegde HV, Chattopadhyay D.

Psicologia e diabetes no Brasil: um mapeamento de profissionais e de suas ações / Psychology and diabetes in Brazil: the mapping of professionals and their practices / Psicología y diabetes en Brasil: un mapeo de los profesionales y sus acciones

Pouco se sabe sobre a atuação do psicólogo no Brasil junto a pessoas com Diabetes Mellitus. O objetivo desta pesquisa foi identificar os psicólogos brasileiros que trabalham com essa população e suas ações. Foram convidados a responder a um questionário online psicólogos que atuam ou atuaram junto a pessoas com diabetes. Participaram 79 psicólogos, principalmente da região Sudeste (59,5%). Todos declararam que haviam cursado pósgraduação. Na amostra, predominou o gênero feminino (89,9%), com idade entre 26 e 40 anos (46,8%). A maioria dos que atuam com diabetes declarou-se autônoma ou voluntária, e quase metade trabalhava menos do que 10 horas semanais. Entre aqueles que deixaram de trabalhar com diabetes, apenas uma minoria tinha vínculo empregatício. Além do trabalho com pessoas com diabetes, a maior parte declarou exercer outras atividades profissionais, como atendimentos clínicos em consultórios particulares, sugerindo que esta não é a atividade principal. Majoritariamente, os respondentes declararam não ter conhecimentos suficientes para o atendimento específico às pessoas com diabetes. Discute-se a qualidade da formação profissional dos psicólogos no Brasil, a necessidade de aprimoramento em relação à atuação com pessoas com diabetes e as condições de trabalho.(AU)

Little is known about the practice of psychologists in Brazil caring for people with Diabetes Mellitus. The aim of this research was to identify the Brazilian psychologists who work with this population and describe their actions. Psychologists who work or have worked with people diagnosed with diabetes were invited to answer an online questionnaire. The 79 participants lived mainly in the Southeast Region (59.5%). All of them declared to have a graduate degree, most were female (89.9%), aged 26 to 40 years (46.8%). Most of those working with diabetes declared to be autonomous or voluntary, and almost half had a workload of less than 10 hours a week. Among those who stopped working with diabetes, only a minority had a formal employment contract. In addition, most of them stated that they had other professional activities related to clinical care in private offices, suggesting that working with diabetes is not their main activity. Mostly, respondents stated that they did not have enough knowledge to care for people with diabetes. The quality of professional education of psychologists in Brazil, the need for specific improvement in labor relations and conditions were discussed.(AU)
