Classification of type 2 diabetes mellitus with or without cognitive impairment from healthy controls using high-order functional connectivity.

Type 2 diabetes mellitus (T2DM) is associated with cognitive impairment and may progress to dementia. However, the brain functional mechanism of T2DM-related dementia is still less understood. Recent resting-state functional magnetic resonance imaging functional connectivity (FC) studies have proved its potential value in the study of T2DM with cognitive impairment (T2DM-CI). However, they mainly used a mass-univariate statistical analysis that was not suitable to reveal the altered FC "pattern" in T2DM-CI, due to lower sensitivity. In this study, we proposed to use high-order FC to reveal the abnormal connectomics pattern in T2DM-CI with a multivariate, machine learning-based strategy. We also investigated whether such patterns were different between T2DM-CI and T2DM without cognitive impairment (T2DM-noCI) to better understand T2DM-induced cognitive impairment, on 23 T2DM-CI and 27 T2DM-noCI patients, as well as 50 healthy controls (HCs). We first built the large-scale high-order brain networks based on temporal synchronization of the dynamic FC time series among multiple brain region pairs and then used this information to classify the T2DM-CI (as well as T2DM-noCI) from the matched HC based on support vector machine. Our model achieved an accuracy of 79.17% in T2DM-CI versus HC differentiation, but only 59.62% in T2DM-noCI versus HC classification. We found abnormal high-order FC patterns in T2DM-CI compared to HC, which was different from that in T2DM-noCI. Our study indicates that there could be widespread connectivity alterations underlying the T2DM-induced cognitive impairment. The results help to better understand the changes in the central neural system due to T2DM.

Delayed Gastric Emptying Associates With Diabetic Complications in Diabetic Patients With Symptoms of Gastroparesis.

OBJECTIVES: Diabetic gastroparesis (Gp) occurs more often in type 1 diabetes mellitus (T1DM) than in type 2 diabetes mellitus (T2DM). Other diabetic end-organ complications include peripheral neuropathy, nephropathy, and retinopathy (together termed triopathy). This study determines the prevalence of diabetic complications (retinopathy, nephropathy, and peripheral neuropathy) in diabetic patients with symptoms of Gp, assessing the differences between T1DM and T2DM and delayed and normal gastric emptying (GE). METHODS: Diabetic patients with symptoms of Gp underwent history and physical examination, GE scintigraphy, electrogastrography with water load, autonomic function testing, and questionnaires assessing symptoms and peripheral neuropathy. RESULTS: One hundred thirty-three diabetic patients with symptoms of Gp were studied: 59 with T1DM and 74 with T2DM and 103 with delayed GE and 30 without delayed GE. The presence of retinopathy (37% vs 24%; P = 0.13), nephropathy (19% vs 11%; P = 0.22), and peripheral neuropathy (53% vs 39%; P = 0.16) was not significantly higher in T1DM than in T2DM; however, triopathies (all 3 complications together) were seen in 10% of T1DM and 3% of T2DM (P = 0.04). Diabetic patients with delayed GE had increased prevalence of retinopathy (36% vs 10%; P = 0.006) and number of diabetic complications (1.0 vs 0.5; P = 0.009); however, 39% of diabetic patients with delayed GE did not have any diabetic complications. DISCUSSION: In diabetic patients with symptoms of Gp, delayed GE was associated with the presence of retinopathy and the total number of diabetic complications. Only 10% of patients with T1DM and 3% of those with T2DM had triopathy of complications, and 39% of diabetic patients with Gp did not have any diabetic complications. Thus, the presence of diabetic complications should raise awareness for Gp in either T1DM or T2DM; however, diabetic Gp frequently occurs without other diabetic complications.

MALAT1 as a Diagnostic and Therapeutic Target in Diabetes-Related Complications: A Promising Long-Noncoding RNA.

Diabetes mellitus is a global issue with increasing incidence rate worldwide. In an uncontrolled case, it can advance to various organ-related complications leading to an increase in morbidity and mortality. Long non-coding RNA (lncRNA) Metastasis-associated lung adenocarcinoma transcript 1 (MALAT1) appears to be a fairly novel lncRNA that is relevant to diabetes and its role in diabetic-related diseases initiation and progression have long been a subject of attention to many scholars. The expression of MALAT1 is elevated in different diabetic-related diseases. In this review, we demonstrate the various functions of MALAT1 in the different diabetes-related complications including ischemic reperfusion injury, retinopathy, cataract, atherosclerosis, cardiomyopathy, non-alcoholic steatohepatitis, gastroparesis, kidney disease, and gestational diabetes. The emerging evidence showed that the role of MALAT1 in diabetic-related complications is both pro-inflammatory and apoptosis in different cell types. These results concluded that MALAT1 is a potential diagnostic and future targeted therapy for diabetes-associated complications.

Novel subgroups of adult-onset diabetes and their association with outcomes: a data-driven cluster analysis of six variables.

BACKGROUND: Diabetes is presently classified into two main forms, type 1 and type 2 diabetes, but type 2 diabetes in particular is highly heterogeneous. A refined classification could provide a powerful tool to individualise treatment regimens and identify individuals with increased risk of complications at diagnosis. METHODS: We did data-driven cluster analysis (k-means and hierarchical clustering) in patients with newly diagnosed diabetes (n=8980) from the Swedish All New Diabetics in Scania cohort. Clusters were based on six variables (glutamate decarboxylase antibodies, age at diagnosis, BMI, HbA1c, and homoeostatic model assessment 2 estimates of ß-cell function and insulin resistance), and were related to prospective data from patient records on development of complications and prescription of medication. Replication was done in three independent cohorts: the Scania Diabetes Registry (n=1466), All New Diabetics in Uppsala (n=844), and Diabetes Registry Vaasa (n=3485). Cox regression and logistic regression were used to compare time to medication, time to reaching the treatment goal, and risk of diabetic complications and genetic associations. FINDINGS: We identified five replicable clusters of patients with diabetes, which had significantly different patient characteristics and risk of diabetic complications. In particular, individuals in cluster 3 (most resistant to insulin) had significantly higher risk of diabetic kidney disease than individuals in clusters 4 and 5, but had been prescribed similar diabetes treatment. Cluster 2 (insulin deficient) had the highest risk of retinopathy. In support of the clustering, genetic associations in the clusters differed from those seen in traditional type 2 diabetes. INTERPRETATION: We stratified patients into five subgroups with differing disease progression and risk of diabetic complications. This new substratification might eventually help to tailor and target early treatment to patients who would benefit most, thereby representing a first step towards precision medicine in diabetes.

Risk factors and complications in type 2 diabetes outpatients.

OBJECTIVE: Our study investigated type 2 diabetes mellitus (T2DM) outpatients attending a university hospital in Montes Claros, MG, to estimate the prevalence of risk factors and their association with diabetes complications. METHOD: This was a quantitative, documental, retrospective and analytical study. Medical records of 95 outpatients with T2DM treated in this hospital from 2011 to 2015 were analyzed. Data were collected according to a structured questionnaire surveying sociodemographic, anthropometric and biochemical data and clinical and lifestyle aspects. Regression analysis was used to evaluate the association between risk factor variables and complications. RESULTS: With a mean age of 54 years, the study population showed irregular blood glucose control, despite the use of hypoglycemic medication, and did not have a healthy lifestyle. The main complication reported was high blood pressure (HBP), occurring in 70.9% of patients. The prevalence of complications was positively associated with patients receiving insulin treatment (p=0.042) and multidisciplinary monitoring (p=0.050). CONCLUSION: The associations identified reflect the condition of patients that were already treating diabetes and its complications, especially HBP. The characteristics of the study population indicate the need to improve clinical follow-up and increase motivation for healthy behaviors.

Resultados: Com média de 54 anos de idade, a população estudada tinha controle glicêmico irregular, fazia uso de hipoglicemiantes e não adotava um estilo de vida saudável. A principal complicação reportada foi hipertensão arterial, presente em 70,9% dos casos. A prevalência de complicações associou-se positivamente com adoção de tratamento insulínico (p=0,042) e acompanhamento multidisciplinar (p=0,050). Conclusão: As associações encontradas refletem a condição de pacientes que já tratam a diabetes e suas complicações, principalmente a hipertensão arterial. Características da população indicam a necessidade de melhoria do acompanhamento clínico e o incentivo à adoção de hábitos comportamentais saudáveis.

Identifying and acting on potentially inappropriate care? Inadequacy of current hospital coding for this task.

INTRODUCTION: Recent Australian attempts to facilitate disinvestment in healthcare, by identifying instances of 'inappropriate' care from large Government datasets, are subject to significant methodological flaws. Amongst other criticisms has been the fact that the Government datasets utilized for this purpose correlate poorly with datasets collected by relevant professional bodies. Government data derive from official hospital coding, collected retrospectively by clerical personnel, whilst professional body data derive from unit-specific databases, collected contemporaneously with care by clinical personnel. AIM: Assessment of accuracy of official hospital coding data for hyperbaric services in a tertiary referral hospital. METHODS: All official hyperbaric-relevant coding data submitted to the relevant Australian Government agencies by the Royal Hobart Hospital, Tasmania, Australia for financial year 2010-2011 were reviewed and compared against actual hyperbaric unit activity as determined by reference to original source documents. RESULTS: Hospital coding data contained one or more errors in diagnoses and/or procedures in 70% of patients treated with hyperbaric oxygen that year. Multiple discrete error types were identified, including (but not limited to): missing patients; missing treatments; 'additional' treatments; 'additional' patients; incorrect procedure codes and incorrect diagnostic codes. Incidental observations of errors in surgical, anaesthetic and intensive care coding within this cohort suggest that the problems are not restricted to the specialty of hyperbaric medicine alone. Publications from other centres indicate that these problems are not unique to this institution or State. CONCLUSIONS: Current Government datasets are irretrievably compromised and not fit for purpose. Attempting to inform the healthcare policy debate by reference to these datasets is inappropriate. Urgent clinical engagement with hospital coding departments is warranted.

Diabetes Complications Severity Index (DCSI)-Update and ICD-10 translation.

AIMS: The Diabetes Complications Severity Index (DCSI) converts diagnostic codes and laboratory results into a 14-level metric quantifying the long-term effects of diabetes on seven body systems. Adoption of the International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) necessitates translation from ICD-9-CM and creates refinement opportunities. METHODS: ICD-9 codes for secondary and primary diabetes plus all five ICD-10 diabetes categories were incorporated into an updated tool. Additional modifications were made to improve the accuracy of severity assignments. SUBJECTS: The tools were tested in a Medicare Advantage population. RESULTS: In the type 2 subpopulation, prevalence steadily declined with increasing score according to the updated DCSI tool, whereas the original tool resulted in an aberrant local prevalence peak at DCSI = 2. In the type 1 subpopulation, score prevalence was greater in type 1 versus type 2 subpopulations (3 versus 0) according to both instruments. Both instruments predicted current-year inpatient admissions risk and near-future mortality, using either purely ICD-9 data or a mix of ICD-9 and ICD-10 data. DISCUSSION: While the performance of the tool with purely ICD-10 data has yet to be evaluated, this updated tool makes assessment of diabetes patient severity and complications possible in the interim.

Cause-specific mortality in a cohort of Brazilian patients with type 1 diabetes.

AIMS: To assess cause-specific mortality in a cohort of patients with type 1 diabetes (T1D) followed at an university hospital (tertiary level, Rio de Janeiro city) and an outpatient clinic (secondary level, Bauru city) both in Brazil's southeast, and associations of survival with gender, age at diagnosis, self-reported ethnicity and diabetes duration. METHODS: Our study is based on a cohort of patients with T1D whose vital status was determined as of December 31, 2015. The causes of mortality were determined by death certificates and outpatient clinic records. RESULTS: Among 986 patients, (54.4%) females, (74.8%) Caucasians, 886 (89.9%) were alive, 62 (6.3%) had died, and in 38 (3.9%) the vital status was unknown. Median age at death [interquartile range] and diabetes duration until death were 30.0 [13] and 15.6 [10] years, respectively. Considering those who died (n = 62), most patients (about 70%) died from end-stage renal disease, macrovascular disease or acute complications of diabetes, mainly diabetic ketoacidosis. The other causes of mortality were infections, fatal accidents and non-diabetes-related. The standardized mortality ratio was 3.13 [2.35-4.08] in those aged under 40. In a multivariate Cox model, "age < 40 years" and "year of diagnosis" were the only significant variables with hazard ratios of 6.259 [(3.100-12.639), p < 0.001] and 0.915 [(0.880-0.951), p < 0.001], respectively. CONCLUSIONS: Our study shows that patients with T1D had a threefold increase in mortality. The specific causes of mortality were mainly diabetes-related chronic complications; however, acute complications, especially diabetic ketoacidosis, persisted as an important cause of mortality.

Unsatisfactory glycemic control in type 2 Diabetes mellitus patients: predictive factors and negative clinical outcomes with the use of antidiabetic drugs

ABSTRACT Many factors can interfere with glycemic control in patients with type 2 diabetes mellitus and this patient group has an increased risk of experiencing drug-related negative outcomes (DNO). The aim of this study was to identify the predictive factors of unsatisfactory glycemic control and DNO in this group of patients. A cross-sectional study was conducted collecting data from prescriptions and interviews with 100 patients of the Endocrinology Clinic of the Hospital Complex of Sorocaba, São Paulo, Brazil. Variables associated with unsatisfactory glycemic control were determined and the DNO associated with antidiabetic drugs identified. Age (<65 years) (OR=4.09), family history of diabetes (OR=3.24), use of combined therapy to treat diabetes (2-4 antidiabetic drugs) (OR=5.13) and presence of DNO (OR=5.92) were found to be predictive factors for poor patient glycemic control. DNO were observed in 49% of the patients and were caused predominantly by ineffectiveness in patients with poor glycemic control (p<0.05). There was no significant difference between groups (satisfactory and unsatisfactory glycemic control) for DNO caused by safety issues (p>0.05). Characterization of the profile of patients with uncontrolled diabetes and of aspects associated with drug treatment can contribute to the planning of interventions to improve patient care

[Effectiveness of diffuse diabetic macular edema treatment in relation to structural changes in macular region]. / Effektivnost' lecheniya diffuznogo diabeticheskogo makulyarnogo oteka v zavisimosti ot strukturnykh izmenenii makulyarnoi oblasti.

AIM: to describe baseline functional and anatomical parameters of the macular region and how they change under ranibizumab therapy depending on the type of diabetic macular edema (DME) determined with optical coherence tomography (OCT). MATERIAL AND METHODS: The study included 100 patients (100 eyes) with diabetes mellitus and DME (38 men and 62 women) aged 61.9±5.6 years with the mean disease duration of 8.48 years. Basing on OCT findings, 4 groups (25 patients each) were formed: sponge-like DME, cystoid DME, DME with serous neuroepithelium detachment (NED), and mixed DME (cystoid DME and serous NED). All patients received 3 consecutive monthly injections of 0.5 mg ranibizumab. The relationship between anatomical, functional, and clinical parameters was analyzed. RESULTS: The lowest visual acuity (VA) at baseline was found in patients with mixed DME (р<0.05). The greatest increase in VA after the 3 injections was noted in patients with sponge-like DME - 0.34±0.18. Retinal thickness was significantly lower (р<0.05) in sponge-like DME as compared to other groups both at baseline and after the treatment. Foveolar thickness decreased after the treatment in all groups, the effect being the most pronounced (the edema got reduced by 42.4%, р<0.05) in cystoid DME. The most significant reduction in macular volume (by 2.7 mm3) as well as its lowest absolute post-treatment values were reported for patients with cystoid edema (9.01 mm3, р<0.05 as compared to sponge-like and mixed DME). Correlation analysis revealed an evident relationship between the improvement in VA (ΔVA) and the decrease in macular volume (р<0.05). Of clinical parameters, only diabetes duration correlated with the extent of VA improvement (r=-0.3; p<0.05). CONCLUSION: The effectiveness of intravitreal ranibizumab therapy for diffuse DME depends on the morphological type of macular edema by OCT. Moreover, it correlates with diabetes duration.

Malignant Otitis Externa: A Novel Stratification Protocol for Predicting Treatment Outcomes.

OBJECTIVES: 1) Stratify malignant otitis externa into severe and nonsevere disease categories. 2) Predict treatment courses and outcomes based on this stratification. SETTING: Tertiary center. PATIENTS: Retrospective review 2004 to 2014; 28 patients. Inclusion criteria are a diagnosis by senior authors, radiographic evidence of disease, admission for intravenous antibiotics/debridement, minimum 1 year of follow-up. INTERVENTIONS: Severe group stratification if two or more of the following: cranial nerve VII palsy, fungal positive culture, relapse, surgery performed, major radiographic findings. All other patients stratified to nonsevere group. MAIN OUTCOME MEASURES: Cure, alive/refractory disease, death by disease, death by other cause. Secondary measures are antibiotic duration and number of disease-related admissions. RESULTS: Forty-three percent (12 of 28) and 57% (16 of 28) of patients stratified into the severe and nonsevere groups. The severe group had significantly more adverse disease-specific outcomes than the nonsevere group (7 of 12 versus 0 of 16; p = 0.002). Disease-specific mortality was 42% and 0% in the severe and nonsevere groups, respectively. The severe group had longer antibiotic courses (12.8 versus 6.9 wk; p = 0.01) and more disease-related admissions/relapses (1.6 versus 1, p < 0.001). Only four of 12 severe group patients achieved cure. All but two nonsevere patients achieved cure, with those two dying of other causes. CONCLUSION: A subgroup of malignant otitis externa may exist that is not as susceptible to parenteral antibiotics and local debridement. A combination of clinical and radiographic findings may be useful for stratifying patients into severe/nonsevere categories. Patients with severe disease may be more likely to die of their disease and have worse treatment courses such that additional surgical intervention may be indicated.

Screening and treatment by the primary care provider of common diabetes complications.

Diabetes is the leading cause of end-stage renal disease, blindness, and nontraumatic lower-limb amputation. The largest reductions in cardiovascular events are seen when multiple risk factors are addressed simultaneously. The benefit of aspirin as secondary prevention in patients with previous stroke or myocardial infarction has been well established. Regular, dilated eye examinations are effective in detecting sight-threatening diabetic retinopathy and have been shown to prevent blindness. The use of appropriate tools and clinical examination/inspection provides greater than 87% specificity in detecting diabetic peripheral neuropathy. Early treatment of risk factors, including hypertension, hyperglycemia, and dyslipidemia can delay or prevent diabetic nephropathy.

Acute myocardial infarct size is related to periodontitis extent and severity.

Cardiovascular disease has been associated with 40% of deaths in high-income countries and 28% in lower-income countries. The relationship between periodontitis and acute myocardial infarction is well documented, but it has not been established whether the extent and severity of periodontitis influence the infarct size. This cross-sectional and analytic study was designed to investigate the association of chronic periodontitis extent and severity with acute myocardial infarct size as indicated by serum cardiac troponin I and myoglobin levels. Sociodemographic, periodontal, cardiologic, and hematologic variables were gathered in 112 consecutive patients with myocardial infarction. The extent (Arbes Index) and severity (Periodontal Inflammatory Severity Index) of the chronic periodontitis were significantly associated with troponin I levels after controlling for sociodemographic and clinical confounders (change in R (2) = .041, p < .02, and R (2) = .031, p = .04). However, only the extent index accounted for levels of myoglobin (change in R (2) = .030, p < .05), total leukocytes (change in R (2) = .041 p < .02), and neutrophils (change in R (2) = .059, p < .01). Mediated regression analysis showed that leukocytes and neutrophils may underlie these observed relationships of chronic periodontitis with troponin I and myoglobin. To our knowledge, this study contributes the first research data demonstrating that the extent and severity of periodontitis is positively associated with acute myocardial infarct size as measured by serum troponin I and myoglobin levels.

Pharmaceutical consultation as a tool to improve health outcomes for patients with type 2 diabetes

This study develops and evaluates a pharmaceutical consultation program (PCP) to improve treatment for Type 2 diabetes patients (T2DP) and reduce risk factors for diabetic complications with possible application in other chronic diseases. We recruited T2DP receiving conventional medical treatment but with fasting glycemia >140mg/dl and/or glycated hemoglobin >7%. The PCP includes strategies obtained from Dader's method, the PWDT (Pharmacist's Workup of Drug Therapy method) model of pharmaceutical care, the SOAP (Subjective data, Objective data, Assessment, and Plan of care) method, and concepts based on a nursing care model. The PCP evaluated lifestyle, pharmacotherapy and monitoring it using laboratory tests, vital signs, and anthropometry. These procedures were repeated every 4 months for 1 year. Data obtained in each consultation were used to provide patient education focusing on healthy lifestyles and medications. Fifty patients completed the PCP. There were reductions in glycemia (P<0.0001), glycated hemoglobin (P=0.0022), cholesterolemia (P=0.0072), triacylglycerolemia (P=0.0204) and blood pressure (P<0.0001). Increased concordance with drug treatment and correction of drug-related problems contributed to improved treatment. We can therefore conclude that our PCP was suitable for improving health outcomes in T2DP by reducing risk factors for diabetic complications.

Neste estudo, desenvolvemos e avaliamos um programa de consulta farmacêutica (PCF) visando melhorar o tratamento de pacientes diabéticos tipo 2 (PDT2) e reduzir os fatores de risco de complicações diabéticas com possibilidade de aplicação em outras doenças crônicas. Para alcançar este propósito, PDT2 recebendo tratamento médico convencional, apresentando glicemia de jejum > 140 mg/dl e/ou hemoglobina glicada >7% foram selecionados. O PCF inclui estratégias obtidas a partir do método de Dader, do modelo de cuidados farmacêuticos PWDT (Pharmacist's Workup of Drug Therapy method), do método SOAP (Subjective data, Objective data, Assessment, and Plan of care) e conceitos baseados em um modelo de cuidados em enfermagem. O PCF avaliou o estilo de vida, farmacoterapia e seu monitoramento através de exames laboratoriais, sinais vitais e antropometria. Estes procedimentos foram repetidos a cada 4 meses durante 1 ano. Os dados obtidos em cada consulta possibilitaram oferecer educação focada no estilo de vida e uso de medicamentos. Para os 50 pacientes que concluiram o PCF houve redução da glicemia (P < 0.0001), hemoglobina glicada (P = 0.0022), colesterolemia (P = 0.0072), triacilgliceridemia (P= 0.0204) e pressão arterial (P < 0.0001). O aumento da concordância e a correção dos problemas relacionados a medicamentos contribuíram para melhoria do tratamento. Assim, podemos concluir que o PCF foi adequado para melhorar a saúde de PDT2 ao reduzir fatores de risco de complicações diabéticas.
