A Comparative Analysis of Diabetes Self-Care and Treatment Adherence Among Patients with Type 2 Diabetes Mellitus With and Without Cancer

Subclinical left ventricular (LV) dysfunction is prevalent in type 2 diabetes (T2DM). As obesity has been proposed as one causal factor in the disease process, this could bias the reported prevalences. We wanted to characterize echocardiographic LV dysfunction in obese T2DM subjects as compared to non-diabetic obese controls. One hundred patients with T2DM without clinical signs of heart failure (29% females, mean ± SD age 58.4 ± 10.5 years, body mass index (BMI) 30.1 ± 5.5 kg/m(2), blood pressure (BP) 141 ± 18/83 ± 9 mmHg) and 100 non-diabetic controls (29% females) matched for age (58.6 ± 10.5 years), BMI (29.8 ± 4.0 kg/m(2) and systolic BP (140 ± 14 mmHg) underwent echocardiography and color tissue Doppler imaging (TDI). Diastolic function was evaluated with conventional Doppler recordings and early (e') and late (a') myocardial velocities. The ratio between early transmitral filling (E) and the corresponding myocardial tissue velocity (e') served as an index of LV filling pressure. T2DM patients had more concentric hypertrophy with a relative wall thickness of 0.42 ± 0.07 vs controls 0.38 ± 0.07, P < 0.001. The T2DM group had signs of diastolic dysfunction with lower E/A ratio (0.91 ± 0.27 vs. 1.12 ± 0.38, P < 0.001), deceleration time (195 ± 49 vs 242 ± 72 ms, P < 0.001), e' (5.7 ± 2.0 vs. 6.6 ± 1.8 cm/s, P = 0.001), and a' (6.5 ± 2.0 vs. 7.6 ± 1.5 cm/s, P < 0.001) compared to the controls, and higher E/e' (13.3 ± 4.7 vs. 11.1 ± 3.5, P < 0.001). Thus, there were indications of pseudo normalization and increased filling pressure in the T2DM group, whereas the controls had evidence for relaxation abnormalities without elevated filling pressure. Compared to a non-diabetic obese group, more advanced subclinical impairment of diastolic function was seen in T2DM.

The studies on the risk of tuberculosis (TB) in patients with type 1 diabetes mellitus (T1DM) alone are limited. We examined this relationship using a population-based retrospective cohort study. From claims data of the National Health Insurance system of Taiwan, we identified 5195 patients with T1DM newly diagnosed from 2002 to 2011 and 20,780 randomly selected controls without T1DM, frequency matched by age, sex, and year of diagnosis. Both cohorts were followed up until the end of 2011 to evaluate the risk of TB. The overall incidence of TB was 4.07-fold higher in the T1DM cohort than in the control cohort (1.18 vs 0.29 per 1000 person-years, P < 0.001). Compared with the controls, the Cox model estimated adjusted hazard ratios (HRs) of TB in patients with T1DM were greater in men than in women (4.62 vs 3.59) and in adults than in children (4.06 vs 3.37), but not significant. The adjusted HR was much greater for those with comorbidities than those without comorbidities (14.6 vs 1.62, P < 0.001). Compared with the controls, the patients with T1DM were also more likely to develop TB with multiple emergency room visits (adjusted HR: 116.1, 95% confidence interval [CI] = 43.8–307.4) or hospitalizations (adjusted HR: 86.5, 95% CI = 33.7–222.4). Patients with T1DM are at elevated risks of developing TB with much higher HRs for those with comorbidities, within the first year of diagnosis, and with frequent emergency cares or hospitalizations.

Objective: This study aimed to characterize the sociodemographic and clinical profiles of Portuguese patients with type 2 diabetes mellitus (T2DM) and to assess their self-care practices, treatment adherence, motivation, and satisfaction with social support. Methods: A cross-sectional observational study was conducted at an endocrinology unit in northern Portugal from January 2021 to December 2022. The sample included 303 adult patients with T2DM who provided informed consent. Data were collected using a structured questionnaire addressing sociodemographic, clinical, and self-care aspects. Validated scales were used to assess diabetes knowledge, self-care activities, treatment adherence, motivation, and social support. Results: Of the 303 patients enrolled, with a median age of 67 years, 51.2% were female and 68.2% retired. Clinical measures showed a median systolic blood pressure of 135 mmHg, abdominal circumference of 104.6 cm, and BMI of 29.3 kg/m2. Self-care practices were suboptimal, with only 25.1% of patients consistently following a healthy diet, and 31% engaged in weekly physical activity. Although treatment adherence was generally high, issues like forgetfulness were reported. Satisfaction with social support varied, with 30% of patients feeling isolated. Conclusions: The study identifies significant gaps in diet and physical activity adherence among T2DM patients. There is a need for targeted educational interventions and enhanced support systems to improve self-care and treatment outcomes. Personalized care strategies addressing educational, motivational, and social support factors are crucial to better managing T2DM and improving patient well-being.

BackgroundCoronary artery disease (CAD) confers considerable morbidity and mortality in diabetes. However, the role of CAD in additive effect of left ventricular (LV) function has rarely been explored in type 2 diabetes mellitus (T2DM) patients. This study aimed to investigate how CAD affect LV systolic and diastolic function in T2DM patients.Materials and methodsA total of 282 T2DM patients {104 patients with CAD [T2DM (CAD +)] and 178 without [T2DM (CAD −)]} and 83 sex- and age- matched healthy controls underwent cardiac magnetic resonance scanning. LV structure, function, global strains [including systolic peak strain (PS), peak systolic (PSSR) and diastolic strain rate (PDSR) in radial, circumferential and longitudinal directions] and late gadolinium enhancement (LGE) parameters were measured. T2DM (CAD +) patients were divided into two subgroups based on the median of Gensini score (60) which was calculated to assess the severity of CAD. Multivariable linear regression analyses were constructed to investigate the determinants of reduced LV function.ResultsCompared with normal controls, T2DM (CAD −) patients exhibited increased LV end-diastolic and end-systolic volume index and decreased LV global strains, while T2DM(CAD +) patients showed more marked increase and decrease than T2DM(CAD-) and healthy controls, except for longitudinal PDSR (PDSR-L) (all P < 0.017). All of LV global strains demonstrated a progressive decrease from normal controls, through Gensini score ≤ 60, to Gensini score > 60 group, except for PDSR-L (all P < 0.017). CAD was an independent predictor of reduced LV global circumferential PS (GCPS, β = 0.22, p < 0.001), PSSR (PSSR-C, β = 0.17, p = 0.005), PDSR (PDSR-C, β = 0.22, p < 0.001), global radial PS (GRPS, β = 0.19, p = 0.001), and global longitudinal PS (GLPS, β = 0.18, p = 0.003) in T2DM. The Gensini score was associated with decreased GCPS, PSSR-C, PDSR-C, GRPS, and GLPS in T2DM (CAD +) (all p < 0.05).ConclusionCAD has an additive deleterious effect on LV systolic and diastolic function in T2DM patients. Among T2DM (CAD +) patients, the Gensini score is associated with reduced LV contractile and diastolic function.Trial registration Retrospectively registered

High sensitivity C-reactive protein (Hs-CRP) is a sensitive marker of subclinical inflammation associated with atherosclerosis. Uncontrolled diabetes mellitus (DM) is one of the important risk factors of coronary heart disease (CHD). The aim of this study was to evaluate the association between Hs-CRP levels and both glycaemic control and CHD in Syrian type 2 diabetes mellitus (T2DM) patients. A random sample of 108 subjects was selected from T2DM and/or CHD patients seen in the National Centre for Diabetes, and the outpatient clinic of cardiology department at Tishreen University Hospital in Latakia. Four groups were formed: Group 1 [T2DM (+) CHD (-), N=29], Group 2 [T2DM (-) CHD (+), N=25], Group 3 [T2DM (+) CHD (+), N=29], and Group 4 (T2DM (-) CHD (-), N=25). Serum Hs-CRP and glycated haemoglobin (HBA1C) were determined. The SPSS 25.0 program was used for the statistical analysis. Probability (P) value less than 0.05 was considered statistically significant. Mean Hs-CRP level was higher in T2DM subjects with (5.23±1.56mg/l) or without (2.29±0.78mg/l) CHD compared to T2DM (-) CHD (-) patients (0.16±0.04mg/l), (p&lt;0.0001 for both). Mean Hs-CRP level in T2DM with CHD was not only higher than T2DM patients without CHD (p&lt;0.0001), but also than non-diabetic subjects with CHD (2.56±0.45mg/l) (p&lt;0.0001). There was a positive correlation between serum Hs-CRP and HBA1C in T2DM patients with CHD (r=0.781, P&lt;0.0001), Similarly, Hs-CRP levels were positively and significantly correlated with HBA1C in T2DM patients without CHD (r=0.800, p&lt;0.0001). We also noticed that for every 1.0% increase in HbA1c there was an 77% increase in the likelihood of having an elevated Hs-CRP. We concluded that Hs-CRP was strongly correlated with glycaemic control in T2DM patients. The highest Hs-CRP level was observed in T2DM with CHD patients. Hs-CRP could predict the incidence of coronary heart disease in T2DM patients.

Introduction Serum urea and creatinine levels are the most commonly recognized parameters for evaluating renal impairment in patients with diabetes mellitus (DM). Therefore, this study evaluated the correlation between urea and creatinine levels and thiamin levels in patients with type 1 DM (T1DM) and type 2 DM (T2DM). Methods This multi-center, cross-sectional study was conducted at diabetic outpatient clinics in Karachi. The duration of the study was six months, from 1st January 2023 to 30th June 2023. A total of 60 patients were enrolled and divided into two groups, i.e., T1DM and T2DM, each containing 30 patients of both genders between the ages of 24 and 42 years. Demographic data and biochemical variables, such as urea, creatinine, random blood sugar, fasting blood sugar, hemoglobin A1c, and serum thiamin levels, were assessed. The Mann-Whitney U test and independent t-test were used to associate the means between the two study groups. The chi-square test and Spearman's correlation coefficient were used to determine the associations between the variables and T1DM and T2DM. Results The study results revealed that patients with T2DM had a significantly higher frequency of hypertension (p = 0.039), neuropathy (p = 0.038), and coronary artery disease (p = 0.010) than those with T1DM, in both genders. The level of serum thiamin was found to be significantly higher (p < 0.001) in T2DM (14.8 ± 4.82) than in T1DM patients (7.34 ± 1.90). Similarly, serum creatinine was higher in T2DM than in T1DM patients (0.83 ± 0.12 vs. 0.76 ± 0.17, p = 0.025). Moreover, the correlation of urea and creatinine with thiamin levels in T1DM and T2DM patients revealed that in T1DM and T2DM patients, urea and creatinine showed an insignificant positive correlation with thiamin levels. Conclusion We found a significantly higher level of serum creatinine and thiamin levels in T2DM patients than in T1DM; however, there was no significant correlation between urea and creatinine levels and thiamin status in T1DM and T2DM patients. Therefore, we conclude that although serum urea, creatinine, and serum thiamin are important disease biomarkers in diabetic patients, there is no correlation between them.

The relationship between type 1 diabetes mellitus (T1DM) and periodontal disease may exhibit by the alteration of bone metabolism. However, evidence for this relationship is scarce and inconclusive. Thus, the aims of the present study were to investigate salivary receptor activator of nuclear factor kappa-β (RANK), receptor activator of nuclear factor kappa-β ligand (RANKL), osteoprotegerin (OPG) gene expression and the RANKL:OPG ratio in T1DM and non-T1DM. Secondary objective was to determine the relationships of RANK, RANKL and OPG gene expression to clinical parameters of T1DM and periodontal disease. Twenty patients with T1DM and twenty age-matched non-T1DM were recruited. Clinical periodontal parameters were measured. Total RNA was isolated from non-stimulated saliva, and the relative gene expressions of RANK, RANKL, OPG and RANKL:OPG ratio were determined by quantitative real-time polymerase chain reaction. The T1DM group had significantly higher mean periodontal parameters than the non-T1DM group, while the mean plaque scores of both groups were not significantly different. There was a trend of higher relative gene expression of RANK, RANKL, and the RANKL:OPG ratio and lower expression of OPG in T1DM group but no statistic significant different when compared to non-T1DM. In the T1DM group, RANKL:OPG correlated with the percentage of bleeding sites, whereas RANK, RANKL, and HbA1c levels correlated with pocket depth. Bone metabolisms demonstrating by decreased OPG gene expression and upregulated of RANK, RANKL, RANKL:OPG with higher pocket depth and bleeding in T1DM may play an important role in periodontal destruction in T1DM.

Identification of KCNJ15 as a Susceptibility Gene in Asian Patients with Type 2 Diabetes Mellitus

BACKGROUNDDiabetes is becoming increasingly common and has become an important global health issue. In addition to physical damage, diabetes often leads to psychological complications, such as depressive symptoms. Self-care is considered to be the cornerstone of type 2 diabetes mellitus (T2DM) management. This research evaluated depression and explored the associations between self-care activities, self-perceived burden, and depression among T2DM patients in China.AIMTo investigate the self-care activities and the association between depression and self-perceived burden among Chinese inpatients with T2DM.METHODSA cross-sectional study was conducted in participants with T2DM. The data collected encompassed basic characteristics, diabetes self-care activities, depression levels, and self-perceived burdens. Bootstrapping was utilized to assess the mediating role of diabetes self-care activities.RESULTSThere were 599 T2DM patients in the survey, and 71.8% had been diagnosed with the disease for 1–10 years. There were significant correlations between self-care activities, depression, and self-perceived burden. The significant coefficients for paths a (B = -0.281, P < 0.001) and b (B = -0.041, P < 0.05) suggested negative associations between self-perceived burden and self-care behavior and between self-care activities and depression. The indirect effect (path a × b) of self-perceived burden on depression through self-care behaviors was significant (B = 0.020, P < 0.05), with a 95% bias-corrected bootstrap confidence interval of 0.007–0.036.CONCLUSIONThe mediating model presented here highlights the role of self-care activities in exerting both direct and indirect effects on depression in participants with T2DM.

Background: Non-psychotic mental disorders including non-severe depressive, anxiety and organic disorders can have an impact on the course and prognosis of the underlying disease in patients with diabetes mellitus (DM). Therefore, assessment of their epidemiologic aspects is extremely important. Aim: Investigation of the types and prevalence of the major mental disorders among both type 1 DM (T1DM) and type 2 DM (T2DM) in-patients, determination of possible etiology of the organic involvement of the brain in T1DM patients as well as of the rate of diagnostics and management of mental disorders in DM patients in routine medical practice. Materials and methods: Part 1 was a cross-sectional study in 228 consecutive DM patients aged from 18 to 75 years, aimed at detection of current mental disorders. Part 2 was a cross-sectional study in 72 consecutive T1DM patients with in-depth assessment of signs of organic brain involvement. All patients underwent cognitive function tests. Mental disorders were diagnosed by a psychiatrist according to ICD-10 diagnostic criteria. Results: Mental disorders were found in 80.3% of patients, being significantly more prevalent in patients with T2DM (87.9%) than in T1DM patients (57.4%, р&lt;0.0001). Anxiety disorders as a whole were diagnosed as frequently as depressive ones (39.5% and 40.0%, respectively), being the most prevalent both in T1DM (35%) and T2DM (60%). Within the class of anxiety disorders, diabetes-specific phobias of injections and hypoglycemia were noted 8-fold more often (р&lt;0.01) in T1DM than in T2DM patients. Generalized (22.4 versus 9.3%) and organic (18 versus 0%) anxiety disorders as well as unipolar depressive episodes and dysthymia (40.2 versus 25.9%, р&lt;0.05) occurred considerably more often in T2DM than in T1DM patients. In total, signs of organic brain involvement were found in 37% of T1DM patients. Possible etiologic factors of organic brain disorders were as follows: craniocerebral injury including concussion of the brain, severe hypoglycemia, and diabetic ketoacidosis – in 40.7% of patients each; alcohol abuse – 30.7%; arterial hypertension – 22.2%; ante- and intranatal factors – 11.1%; neuroinfections/intoxications and occupational neurotropic factors – in 7.4% each; electric trauma, general malnutrition, stroke, and brain tumor – in 3.7% each. None of the listed potential causes could be found only in one patient with organic brain involvement (3.7%). In T1DM patients, organic brain involvement was nonspecific, and there was no evidence of its association with the level of glycated hemoglobin, acute and chronic vascular diabetic complications. Conclusion: The present investigation revealed a high prevalence of non-severe mental disorders with predominance of generalized anxiety disorders and unipolar protracted depressions in T2DM in-patients and specific phobias in T1DM patients. Organic brain involvement (encephalopathy) occurs in every third young T1DM patient; however, in the majority of cases, its potential etiology is linked with factors unrelated to DM or non-specific for DM (for example, hypoglycemia). In routine medical practice, diagnostics and treatment of mental disorders in DM patients are close to non-existent.

To clarify the expression of N6-methyladenosine (m6 A) modulators involved in the pathogenesis of type 2 diabetes mellitus (T2DM). We further explored the association of serum insulin-like growth factor 2 mRNA-binding proteins 3 (IGF2BP3) levels and odds of T2DM in a high-risk population. The gene expression data set GSE25724 was obtained from the Gene Expression Omnibus, and a cluster heatmap was generated by using the R package ComplexHeatmap. Differential expression analysis for 13 m6 A RNA methylation regulators between nondiabetic controls and T2DM subjects was performed using an unpaired t test. A cross-sectional design, including 393 subjects (131 patients with newly diagnosed T2DM, 131 age- and sex-matched subjects with prediabetes, and 131 healthy controls), was carried out. The associations between serum IGF2BP3 concentrations and T2DM were modeled by restricted cubic spline and logistic regression models. Two upregulated (IGF2BP2 and IGF2BP3) and 5 downregulated (methyltransferase-like 3 [METTL3], alkylation repair homolog protein 1 [ALKBH1], YTH domain family 2 [YTHDF2], YTHDF3, and heterogeneous nuclear ribonucleoprotein [HNRNPC]) m6 A-related genes were found in islet samples of T2DM patients. A U-shaped association existed between serum IGF2BP3 levels and odds of T2DM according to cubic natural spline analysis models, after adjustment for body mass index, waist circumference, diastolic blood pressure, total cholesterol, and triglyeride. Multivariate logistic regression showed that progressively higher odds of T2DM were observed when serum IGF2BP3 levels were below 0.62 ng/mL (odds ratio 3.03 [95% confidence interval 1.23-7.47]) in model 4. Seven significantly altered m6 A RNA methylation genes were identified in T2DM. There was a U-shaped association between serum IGF2BP3 levels and odds of T2DM in the general Chinese adult population. This study provides important evidence for further examination of the role of m6 A RNA methylation, especially serum IGF2BP3 in T2DM risk assessment.

Objective To explore the signs of consistent changes of intestinal flora in type 2 diabetes mellitus (T2DM) and diabetes kidney disease (DKD) patients, by studying the key change characteristics of intestinal flora in these patients. Methods Thirty patients with T2DM,twenty-five patients with DKD were involved. Thirty healthy patients with matching age and sex were also involved as the control group. Fecal and serum specimens were collected from both the study group and the control group. High-throughput sequencing technology was used to sequence the 16S rDNA-v4 region of fecal samples; interleukin-6 (IL-6) and C-reactive protein (CRP) were detected by electrochemical luminescence and immunoturbidimetry. Microbiome analysis software QIIME (v1.9.1) was used to analyze the composition and diversity of intestinal flora. Microbial diversity analysis software LEfSe was used to compare intestinal bacteria markers differences between the study group and the healthy control group. The diagnosis model was established by the random forest method. The change characteristics of intestinal flora function were predicted by the PICRUSt. Results The intestinal flora diversity of DM and DKD patients was significantly different from that of the healthy control group (P<0.05). T2DM and DKD patients harbored lots of similar changes. For example, there was a significant decrease in Lachnospira, Faecalibacterium, Roseburia and Coprococcus(P<0.05). However, there was also a disease-specific pattern of imbalance between the two disease. There was a significant increase in Bacteroides in T2DM patients, and in Lactobacillus, Slackia, Anaerotruncus, Haemophilus and Enterococcus in DKD patients. Functional prediction was also confirmed that T2DM and DKD patients had more consistent changes. The correlation analysis between serum inflammatory indicators of T2DM and DKD and bacteria suggested that the decrease of beneficial bacteria in the intestinal tract of T2DM and DKD patients may be the cause of the increase of serum inflammatory indicators. Conclusion T2DM and DKD patients harbored lots of similar changes in intestinal flora, a decrease of bacteria producing butyrate,but there was also a disease-specific change between the two disease,providing a data basis for further studies to evaluate the risk of nephropathy in patients with diabetes by intestinal flora.
