Aberrant Functional Connectivity of the Posterior Cingulate Cortex in Type 2 Diabetes Without Cognitive Impairment and Microvascular Complications.

Objective: We aimed to investigate the alterations of brain functional connectivity (FC) in type 2 diabetes mellitus (T2DM) patients without clinical evidence of cognitive impairment and microvascular complications (woCIMC-T2DM) using resting-state functional MRI (rs-fMRI) and to determine whether its value was correlated with clinical indicators. Methods: A total of 27 T2DM and 26 healthy controls (HCs) were prospectively examined. Cognitive impairment was excluded using the Mini-Mental State Examination (MMSE) and the Montreal Cognitive Assessment (MoCA) scales, and microvascular complications were excluded by fundus photography, microalbuminuria, and other indicators. The correlation maps, derived from rs-fMRI with posterior cingulate cortex (PCC) as the seed, were compared between T2DM patients and HCs. Pearson's correlation analysis was performed to determine the relationship between the FC of PCC and the clinical indicators. Results: Compared with HC, woCIMC-T2DM patients showed significantly decreased FCs with PCC (PCC-FCs) in the anterior cingulate cortex (ACC), right superior frontal gyrus, right medial frontal gyrus, and right angular gyrus. Meanwhile, increased PCC-FCs was observed in the right superior temporal gyrus and calcarine fissure (CAL). The FC of PCC-ACC was negatively correlated with glycosylated hemoglobin (HbA1c) and diabetes duration, and the FC of PCC-CAL was significantly positively correlated with HbA1c and diabetes duration. Conclusion: The FC, especially of the PCC with cognitive and visual brain regions, was altered before clinically measurable cognitive impairment and microvascular complications occurred in T2DM patients. In addition, the FC of the PCC with cognitive and visual brain regions was correlated with HbA1c and diabetes duration. This indicates that clinicians should pay attention not only to blood glucose control but also to brain function changes before the occurrence of adverse complications, which is of great significance for the prevention of cognitive dysfunction and visual impairment.

Longitudinal associations between depression and diabetes complications: a systematic review and meta-analysis.

To conduct a systematic review and meta-analysis of longitudinal studies assessing the bi-directional association between depression and diabetes macrovascular and microvascular complications. Embase, Medline and PsycINFO databases were searched from inception through 27 November 2017. A total of 4592 abstracts were screened for eligibility. Meta-analyses used multilevel random/mixed-effects models. Quality was assessed using the Newcastle-Ottawa scale. Twenty-two studies were included in the systematic review. Sixteen studies examined the relationship between baseline depression and incident diabetes complications, of which nine studies involving over one million participants were suitable for meta-analysis. Depression was associated with an increased risk of incident macrovascular (HR = 1.38; 95% CI: 1.30-1.47) and microvascular disease (HR = 1.33; 95% CI: 1.25-1.41). Six studies examined the association between baseline diabetes complications and subsequent depression, of which two studies involving over 230 000 participants were suitable for meta-analysis. The results showed that diabetes complications increased the risk of incident depressive disorder (HR = 1.14; 95% CI: 1.07-1.21). The quality analysis showed increased risk of bias notably in the representativeness of selected cohorts and ascertainment of exposure and outcome. Depression in people with diabetes is associated with an increased risk of incident macrovascular and microvascular complications. The relationship between depression and diabetes complications appears bi-directional. However, the risk of developing diabetes complications in depressed people is higher than the risk of developing depression in people with diabetes complications. The underlying mechanisms warrant further research.

Management of cardiovascular disease risk in teens with type 1 diabetes: Perspectives of teens with and without dyslipidemia and parents.

Hypertension and dyslipidemia are often suboptimally managed in teens with type 1 diabetes (T1D). Teen and parent perspectives on hypertension and dyslipidemia management need further study to enhance the development of cardiovascular disease (CVD) risk factor management plans. We sought to describe barriers to and strategies for CVD risk factor management. Teens with T1D with and without dyslipidemia and parents of teens with T1D with and without dyslipidemia underwent one-on-one semi-structured interviews conducted by trained personnel at a diabetes center; interviews continued until thematic saturation was reached. Teens and parents of teens described their knowledge, attitudes, and beliefs regarding heart health and CVD risk factors (hypertension and dyslipidemia). Researchers undertook a content analysis and categorized central themes as strategies and barriers. In total, 22 teens and 25 parents completed interviews. Teens were 17.4 ± 1.7 years old with T1D duration 9.7 ± 4.0 years; 45% had dyslipidemia. Parents were between 41 and 60 years old, 84% were mothers, and 40% had teens with dyslipidemia. Barriers to heart health included an obesity-promoting environment, parental distrust of medications, and limited teen knowledge about hypertension and dyslipidemia. Strategies included specific and realistic guidance from providers, family support of teen lifestyle management, and having exercise partners. While teen and parent perspectives were often similar, some themes applied only to teens or parents. Central themes provide actionable guidance to enhance hypertension and dyslipidemia management. Providers should consider teen and parent perspectives when managing CVD risk factors to enhance engagement with CVD risk management.

Type A competitiveness traits correlate with downregulation of c-Fos expression in patients with type 1 diabetes.

AIM: Type A personality has been associated with increased survival in people with type 1 diabetes (T1D). Systemic low-grade inflammation may play a critical role, as suggested in recent reports, although the links between the inflammatory circulating transcriptome and Type A remain unknown. This prompted our exploration of the potential associations between Type A personality and c-Fos gene expression, a candidate gene closely linked to inflammatory processes, in T1D. METHODS: Type A personality was assessed by Bortner questionnaire in patients with T1D, and two subscales - 'speed' and 'competitiveness' - were used to measure these specific dimensions of Type A. Expression of the c-Fos gene was assessed by a quantitative real-time polymerase chain reaction technique. RESULTS: This pilot study included 20 men with T1D. Multivariable analyses showed an independent inverse association between Type A competitiveness score and c-Fos expression, while a regression model adjusted for age, body mass index and HbA1c levels revealed a significant inverse relationship between c-Fos transcripts and Type A competitiveness (P = 0.003). CONCLUSION: This strong association between Type A competitiveness and reduced c-Fos expression is in line with recent data suggesting a psychobiological influence of the Type A profile in T1D via inflammatory pathways.

High Diabetes Distress Among Ethnic Minorities Is Not Explained by Metabolic, Cardiovascular, or Lifestyle Factors: Findings From the Dutch Diabetes Pearl Cohort.

OBJECTIVE: Diabetes distress among patients from ethnic minorities is still poorly understood. We investigated the association between ethnicity and diabetes distress among ethnic minority groups of people with type 2 diabetes in the Netherlands, focusing on the possible effects of glycemic control, lifestyle factors, cardiovascular risk factors, and diabetes complications. RESEARCH DESIGN AND METHODS: Cross-sectional data from the Dutch Diabetes Pearl cohort included people with type 2 diabetes from primary, secondary, and tertiary diabetes care programs. We used the 20-item Problem Areas in Diabetes Survey (PAID) scale to assess diabetes distress; a score ≥40 is considered to represent high distress. Ethnicity was estimated on the basis of country of birth. Sociodemographic and lifestyle data were self-reported; cardiovascular and metabolic data were retrieved from medical charts. Logistic regression analysis determined the association between ethnicity and diabetes distress, with Caucasians as the reference group. RESULTS: Diabetes distress scores and ethnicity were available for 4,191 people with type 2 diabetes: 3,684 were Caucasian, 83 were Asian, 51 were Moroccan, 92 were African, 134 were Latin American, 46 were Turkish, and 101 were Hindustani-Surinamese. Overall, participants in minority groups had worse health outcomes than those of Caucasian descent, and diabetes distress was more prevalent (ranging from 9.6 to 31.7%, compared with 5.8% among Caucasians), even after adjusting for age, sex, education level, alcohol use, smoking, BMI, lipid profile, HbA1c, medication use, and the presence of diabetes complications. CONCLUSIONS: Among people with type 2 diabetes in the Netherlands, ethnicity is independently associated with high diabetes distress. Further research is warranted to explain the higher prevalence of diabetes distress in minority groups and to develop effective interventions.

Cognitive Function Deficits Associated With Long-Duration Type 1 Diabetes and Vascular Complications.

OBJECTIVE: Patients with type 1 diabetes now live long enough to experience cognitive decline. During middle age, they show mild cognitive deficits, but it is unknown whether severity increases with aging or whether cognitive profiles are similar to those of age-matched peers with and without diabetes. RESEARCH DESIGN AND METHODS: We tested and compared cognition in 82 individuals with 50 or more years of type 1 diabetes (Medalists), 31 age-matched individuals with type 2 diabetes, and 30 age-matched control subjects without diabetes. Medical histories and biospecimens were collected. We also evaluated the association of complications with cognition in Medalists only. RESULTS: Compared with control subjects, both individuals with type 1 diabetes and individuals with type 2 diabetes performed worse on immediate and delayed recall (P ≤ 0.002) and psychomotor speed in both hands (P ≤ 0.01) and showed a trend toward worse executive function (P = 0.05). In Medalists, cardiovascular disease was associated with decreased executive function and proliferative diabetic retinopathy with slower psychomotor speed. CONCLUSIONS: Both patients with type 1 and patients with type 2 diabetes showed overall worse cognition than control subjects. Further, in Medalists, a relationship between complications and cognition was seen. Although both groups with diabetes showed similar deficit patterns, the underlying mechanisms may be different. Now that patients with type 1 diabetes are living longer, efforts should be made to evaluate cognition and to identify modifying behaviors to slow decline.

Patients With Diabetic Foot Disease Fear Major Lower-Extremity Amputation More Than Death.

BACKGROUND: The aim of this study was to identify the most-feared complications of diabetes mellitus (DM), comparing those with diabetic foot pathology with those without diabetic foot pathology. METHODS: We determined the frequency of patients ranking major lower-extremity amputation (LEA) as their greatest fear in comparison to blindness, death, diabetic foot infection (DFI), or end-stage renal disease (ESRD) requiring dialysis. We further categorized the study group patients (N = 207) by their pathology such as diabetic foot ulcer (DFU), Charcot neuroarthropathy, foot infection, or acute neuropathic fractures and dislocations. The control group (N = 254) was comprised of patients with diabetes who presented with common non-diabetes-related foot pathology. RESULTS: A total of 461 patients were enrolled in this study and included 254 patients without diabetic foot complications and 207 patients with diabetic foot problems. When comparing patients with and without diabetic disease, no significant differences were observed with regard to their fear of blindness, DFI, or ESRD requiring dialysis. Patients with diabetic foot disease (61 of 207, 31.9%) were 136% more likely (odds ratio [OR] = 2.36; 95% CI = 1.51-3.70; P = .002] to rank major LEA as their greatest fear when compared with diabetic patients without foot disease (42 of 254, 16.5%) and were 49% less likely (OR = 0.51; 95% CI = 0.34-0.79; P = .002) to rank death as their greatest fear compared with patients without diabetic foot disease. CONCLUSION: Patients with diabetic foot pathology fear major LEA more than death, foot infection, or ESRD. Variables that were associated with ranking LEA as the greatest fear were the presence of a diabetic-related foot complication, duration of DM ≥10 years, insulin use, and the presence of peripheral neuropathy. LEVELS OF EVIDENCE: Level II: Prospective, Case controlled study.

Excess psychosocial burden in women with diabetes and premature acute coronary syndrome.

AIM: Diabetes is a stronger risk factor for acute coronary syndrome for women than men. We investigate whether behavioural and psychosocial factors contribute to the disparity in acute coronary syndrome risk and outcomes among women with diabetes relative to women without diabetes and men. METHODS: Among 939 participants in the GENESIS-PRAXY cohort study of premature acute coronary syndrome (age ≤ 55 years), we compared the prevalence of traditional and non-traditional factors by sex and Type 2 diabetes status. In a case-only analysis, we used generalized logit models to investigate the influence of traditional and non-traditional factors on the interaction of sex and diabetes. RESULTS: In 287 women (14.3% with diabetes) and 652 men (10.4% with diabetes), women and men with diabetes showed a heavier burden of traditional cardiac risk factors compared with individuals without diabetes. Women with diabetes were more likely to be the primary earner and have more anxiety relative to women without diabetes, and reported worse perceived health compared with women without diabetes and men with diabetes. The interaction term for sex and diabetes (odds ratio (OR) 1.40, 95% confidence intervals (95% CI) 0.83-2.36) was diminished after additional adjustment for non-traditional factors (OR 1.12, 95% CI 0.54-2.32), but not traditional factors alone (OR 1.41, 95% CI 0.84-2.36). CONCLUSIONS: We observed trends toward a more adverse psychosocial profile among women with diabetes and incident acute coronary syndrome compared with women without diabetes and men with diabetes, which may explain the increased risk of acute coronary syndrome in women with diabetes and may also contribute to worse outcomes.

Factores psicosocio-inmunogenéticos en pacientes diabéticos con complicaciones vasculares / Psychological, social and immunogenetic factors observed in diabetic patients with vascular complications

El desarrollo de la medicina, la ciencia y los medios científicos técnicos, permiten explicar de manera didáctica e integral con un enfoque dialéctico-materialista los fenómenos complejos y sus interrelaciones entre sistemas, en diferentes entidades clínicas como la diabetes mellitus, objeto del presente trabajo. Describir la interacción entre factores psicosocio-inmuno-genéticos en pacientes diabéticos con complicaciones vasculares, fue el objetivo de nuestro trabajo. Se trabajó con las bases de datos PubMed, MedLine, SciELO, Ebsco y artículos científicos publicados en revistas cubanas entre 2011-2015. Se revisaron trabajos en español, inglés y francés. Se analizó la interrelación dialéctica e indisoluble de la función integradora del sistema inmune con los sistemas nervioso y endocrino, la que descansa en las relaciones entre los fenómenos psíquicos y orgánicos, y esto solo puede comprenderse completamente cuando se tiene en cuenta la interacción del hombre con el medio social en que se desenvuelve, así como la relación de este con la naturaleza, que es en definitiva el centro de su actividad creadora y transformadora y sobre todo el análisis de las implicaciones prácticas que conlleva para el campo de la clínica y la ciencia. Podemos concluir que el conocimiento de las interacciones entre factores psicosocio-inmuno-genéticos en pacientes diabéticos tipo 2 con complicaciones vasculares, es imprescindible para comprender la dinámica de los fenómenos bioquímicos, así como entre los tres sistemas integradores: neurológico, endocrino e inmune que tienen lugar en estos pacientes, lo que posibilita el tratamiento más adecuado y eficaz y la prevención de la enfermedad hereditaria en familias portadoras(AU)

The development of medicine, science and technical scientific devices allow explaining didactically and comprehensively, with a dialectical-materialist approach, complex phenomena and their interrelationships in different clinical conditions such as diabetes mellitus The objectives of this paper were to describe the interaction among psychological, social, and immunogenetic factors in diabetic patients with vascular complications and to address how these factors are associated with immunosupression state of type 2 diabetic patients. For this purpose, worked with PubMed, MedLine, SciELO, EBSCO databases and scientific articles published in 2011-2015 journals were consulted. A number of papers in Spanish, English and French languages were reviewed. The dialectic and permanent interrelation of the integrative function of the immune system with the nervous and endocrine systems, which is based on the relationship between psychic and phenomena, was analyzed. All this can only be fully understood when one takes into account man's interaction with the social environment as well as his relationship with nature, which is ultimately the core of their creative and transforming activity and particularly, the analysis of the practical implications for the clinical and scientific fields. The knowledge of the interactions among systems is imperative to understand homeostasis and dynamics of biochemical phenomena that occur in humans, both in the relationship between the biological and the psychic areas, and in the biological and the socio environmental areas, thus allowing scientific advances in this field for the development of more effective therapeutic and prevention methods(AU)

Adolescent life with diabetes-Gender matters for level of distress. Experiences from the national TODS study.

OBJECTIVE: To examine the relationship between diabetes distress and gender, and the association with glycemic control, social support, health behaviors, and socio-economic status. METHODS: All adolescents, aged 15 to 18 years, in the national, pediatric diabetes registry SWEDIABKIDS with type 1 diabetes were invited to complete an online questionnaire. A total of 2112 teenagers were identified. RESULTS: 453 complete responses were valid for analyses. Young women scored significantly higher on the distress-screening instrument DDS-2. Almost half of the female respondents exhibited moderate to severe diabetes distress-more than twice the proportion than among male respondents (44% vs 19%). Females reported twice as high scores on the fear of hypoglycemia scale (P < 0.0001) and had a higher HbA1c value than males (P < 0.0001). Gender was highly correlated with distress level even when controlling for multiple factors that may affect distress (parameterfemale = 0.4, P = 0.0003). Particular social problems were highly significant, that is, those who trust that their parents can handle their diabetes when necessary were significantly less distressed than others (P = 0.018). Higher HbA1c levels were associated with higher distress scores (P = 0.0005 [female], P = 0.0487 [male]). CONCLUSIONS: Diabetes-related distress is a great burden for adolescents living with diabetes. Actively involved family and friends may reduce diabetes distress, but female adolescents appear to be particularly vulnerable and may need extra focus and support. Our findings indicate that pediatric diabetes teams working with teenagers must intensify the care during this vulnerable period of life in order to reduce the risk of both psychological and vascular complications in young adults.

The development and validation of a novel outcome measure to quantify mobility in the dysvascular lower extremity amputee: the amputee single item mobility measure.

OBJECTIVE: This study describes the development and psychometric evaluation of a novel patient-reported single-item mobility measure. DESIGN: Prospective cohort study. SETTING: Four Veteran's Administration Medical Centers. SUBJECTS: Individuals undergoing their first major unilateral lower extremity amputation; 198 met inclusion criteria; of these, 113 (57%) enrolled. INTERVENTIONS: None. MAIN MEASURES: The Amputee Single Item Mobility Measure, a single item measure with scores ranging from 0 to 6, was developed by an expert panel, and concurrently administered with the Locomotor Capabilities Index-5 (LCI-5) and other outcome measures at six weeks, four months, and 12 months post-amputation. Criterion and construct validity, responsiveness, and floor/ceiling effects were evaluated. Responsiveness was assessed using the standardized response mean. RESULTS: The overall mean 12-month Amputee Single Item Mobility Measure score was 3.39 ±1.4. Scores for transmetatarsal, transtibial, and transfemoral amputees were 4.2 (±1.3), 3.2 (±1.5), and 2.9 (±1.1), respectively. Amputee Single Item Mobility Measure scores demonstrated "large" and statistically significant correlations with the LCI-5 scores at six weeks (r = 0.72), four months (r = 0.81), and 12 months (r = 0.86). At four months and 12 months, the correlation between Amputee Single Item Mobility Measure scores and hours of prosthetic use were r = 0.69 and r = 0.66, respectively, and between Amputee Single Item Mobility Measure scores and Trinity Amputation and Prosthesis Experience Scales functional restriction scores were r = 0.45 and r = 0.67, respectively. Amputee Single Item Mobility Measure scores increased significantly from six weeks to 12 months post-amputation. Minimal floor/ceiling effects were demonstrated. CONCLUSIONS: In the unilateral dysvascular amputee, the Amputee Single Item Mobility Measure has strong criterion and construct validity, excellent responsiveness, and does not exhibit floor/ceiling effects.

Psychosocial Factors in Diabetes and Cardiovascular Risk.

Type 2 diabetes is a chronic disease that is increasing in prevalence globally. Cardiovascular disease is a major cause of mortality and morbidity in diabetes, and lifestyle and clinical risk factors do not fully account for the link between the conditions. This article provides an overview of the evidence concerning the role of psychosocial stress factors in diabetes risk, as well as in cardiovascular complications in people with existing diabetes. Several types of psychosocial factors are discussed including depression, other types of emotional distress, exposure to stressful conditions, and personality traits. The potential behavioral and biological pathways linking psychosocial factors to diabetes are presented and implications for patient care are highlighted.

Brain Activation and Psychomotor Speed in Middle-Aged Patients with Type 1 Diabetes: Relationships with Hyperglycemia and Brain Small Vessel Disease.

Slower psychomotor speed is very common in patients with type 1 diabetes mellitus (T1D), but the underlying mechanisms are not clear. We propose that hyperglycemia is associated with slower psychomotor speed via disruption of brain activation. Eighty-five adults (48% women, mean age: 49.0 years, mean duration: 40.8) with childhood onset T1D were recruited for this cross-sectional study. Median response time in seconds (longer = worse performance) and brain activation were measured while performing a psychomotor speed task. Exposure to hyperglycemia, measured as glycosylated hemoglobin A1c, was associated with longer response time and with higher activation in the inferior frontal gyrus and primary sensorimotor and dorsal cingulate cortex. Higher activation in inferior frontal gyrus, primary sensorimotor cortex, thalamus, and cuneus was related to longer response times; in contrast, higher activation in the superior parietal lobe was associated with shorter response times. Associations were independent of small vessel disease in the brain or other organs. In this group of middle-aged adults with T1D, the pathway linking chronic hyperglycemia with slower processing speed appears to include increased brain activation, but not small vessel disease. Activation in the superior parietal lobe may compensate for dysregulation in brain activation in the presence of hyperglycemia.

The relationship between depressive symptoms and diabetic complications in elderly patients with diabetes: Analysis using the Diabetes Study from the Center of Tokyo Women's Medical University (DIACET).

AIMS: To investigate the association between likelihood or severity of depression and symptoms associated with diabetic complications in elderly Japanese patients with diabetes. METHODS: This single-center cross-sectional study included 4283 patients with diabetes, 65 years and older (mean age was 73 ± 6 years, 38.7% were women, 3.9% had type 1 diabetes). Participants completed a self-administered questionnaire including items on subjective symptoms associated with diabetic microangiopathy, frequency of clinical visits due to vascular diseases (heart diseases, stroke, or gangrene), hospitalization, and the Patient Health Questionnaire-9 (PHQ-9), a simple but reliable measure of depression. The associations between severity of depression and diabetic complications were examined using logistic regression analysis. RESULTS: According to the PHQ-9 scores, patients were classified into the following 3 categories: 0-4 points (n=2975); 5-9 points (n=842); and 10 or more points (n=466). Higher PHQ-9 scores were associated with increased odds ratios for retinopathy, symptoms related to peripheral polyneuropathy and autonomic neuropathy, and end-stage renal disease requiring dialysis after adjustment for age, gender, smoking status, and HbA1c (all p<0.05). CONCLUSIONS: Significant relationships were found between depression severity and chronic diabetic complications among elderly Japanese patients with diabetes.

Factors Influencing Intention to Receive Examination of Diabetes Complications.

PURPOSE: The purpose of this study was to understand the situation of diabetes patients receiving examinations for diabetes complications and to explore the factors influencing their intention to receive examinations for diabetes complications. METHODS: A cross-sectional study was performed that included 251 diabetes patients who visited outpatient clinics in Southern Taiwan. A survey using a self-administered questionnaire was conducted from October 2015 to January 2016. The questionnaire included items on demographic characteristics, perceived susceptibility to diabetes complications, perceived seriousness of diabetes complications, perceived benefits of taking action to receive diabetes complication examinations, perceived barriers to taking action to receive diabetes complication examinations, and the intention to receive diabetes complication examinations. The data were analyzed using regression analysis. RESULTS: The percentage of participants who received fundus, foot, and kidney examinations was 67.7%, 61.4%, and 73.3%, respectively. Every point increase on the perceived barriers to taking action to receive diabetes complication examinations scale increased the intention to receive a foot examination in the following year by 0.91 times (p=.002), and every point increase on the perceived susceptibility to diabetes complications scale increased the intention to receive a kidney examination in the following year by 1.19 times (p=.045). CONCLUSIONS: Nurses should shoulder the responsibility to increase patients' intention to receive examination of diabetes complications. The results of this study can be used to promote nurses' care efficacy in preventing diabetes complications. They can also provide medical institutions with information to establish prevention and control policies for diabetes complications.

Associations between anxiety and depression symptoms and cognitive testing and neuroimaging in type 2 diabetes.

AIMS: Anxiety, depression, accelerated cognitive decline, and increased risk of dementia are observed in individuals with type 2 diabetes. Anxiety and depression may contribute to lower performance on cognitive tests and differences in neuroimaging observed in individuals with type 2 diabetes. METHODS: These relationships were assessed in 655 European Americans with type 2 diabetes from 504 Diabetes Heart Study families. Participants completed cognitive testing, brain magnetic resonance imaging, the Brief Symptom Inventory Anxiety subscale, and the Center for Epidemiologic Studies Depression-10. RESULTS: In analyses adjusted for age, sex, educational attainment, and use of psychotropic medications, individuals with comorbid anxiety and depression symptoms had lower performance on all cognitive testing measures assessed (p≤0.005). Those with both anxiety and depression also had increased white matter lesion volume (p=0.015), decreased gray matter cerebral blood flow (p=4.43×10(-6)), decreased gray matter volume (p=0.002), increased white and gray matter mean diffusivity (p≤0.001), and decreased white matter fractional anisotropy (p=7.79×10(-4)). These associations were somewhat attenuated upon further adjustment for health status related covariates. CONCLUSIONS: Comorbid anxiety and depression symptoms were associated with cognitive performance and brain structure in a European American cohort with type 2 diabetes.

HeLP-Diabetes: randomised controlled trial protocol.

BACKGROUND: Type 2 Diabetes Mellitus (T2DM) is common, affecting nearly 400 million people worldwide. Achieving good health for people with T2DM requires active self-management; however, uptake of self-management education is poor, and there is an urgent need to find better, more acceptable, cost-effective methods of providing self-management support. Web-based self-management support has many potential benefits for patients and health services. The aim of this trial is to determine the effectiveness and cost-effectiveness of a web-based self-management support programme for people with T2DM. METHODS: This will be a multi-centre individually randomised controlled trial in primary care, recruiting adults with T2DM who are registered with participating general practices in England. Participants will be randomised to receive either an evidence-based, theoretically informed, web-based self-management programme for people with T2DM which addresses medical, emotional, and role management, called Healthy Living for People with type 2 Diabetes (HeLP-Diabetes) or a simple information website. The joint primary outcomes are glycated haemoglobin (HbA1c) and diabetes-related distress, measured by the Problem Areas In Diabetes (PAID) questionnaire. Secondary outcomes include cardiovascular risk factors, depression and anxiety, and self-efficacy for self-management of diabetes. Health economic data include health service use, costs due to the intervention, and EQ-5D for calculation of Quality Adjusted Life Years (QALYS). Data will be collected at baseline, 3 months and 12 months, with the primary endpoint at 12 months. Practice nurses, blinded to patient allocation, collect clinical data; patients complete online questionnaires for patient reported measures. A sample size of 350 recruited participants allows for attrition of up to 15 % and will provide 90 % power of detecting at a 5 % significance level a true average difference in the PAID score of 4.0 and 0.25 % change in HbA1c (both small effect sizes). The analysis will follow a pre-specified analysis plan, based on comparing the groups as randomised (intention-to-treat). DISCUSSION: The findings of this trial are likely to be of interest to policy makers, clinicians, and commissioners, all of whom are actively seeking additional forms of self-management support for people with T2DM. TRIAL REGISTRATION: The Trial Registration number is ISRCTN 02123133 ; date of registration 14.2.13.

Resilience in Vulnerable Populations With Type 2 Diabetes Mellitus and Hypertension: A Systematic Review and Meta-analysis.

BACKGROUND: Patients with chronic conditions and limited access to health care experience stressful challenges resulting from the burden of managing both their conditions and their daily life demands. Resilience provides a mechanism of adapting to stressful experiences. We conducted a systematic review and meta-analysis to synthesize the evidence about interventions to enhance resiliency in managing hypertension or type 2 diabetes in vulnerable populations and to assess the efficacy of these interventions on clinical outcomes. METHODS: We searched multiple databases from early inception through February 2015 including randomized controlled trials that enrolled patients with type 2 diabetes or hypertension. All interventions that targeted resilience in vulnerable populations were included. Data were synthesized to describe the characteristics and efficacy of resiliency interventions. We pooled the total effects by calculating standardized mean difference using the random-effects model. RESULTS: The final search yielded 17 studies. All studies were conducted in the United States and generally targeted minority participants. Resiliency interventions used diverse strategies; discussion groups or workshops were the most common approach. CONCLUSIONS: Interventions aimed at enhancing the resiliency of patients from vulnerable groups are diverse. Outcomes were not fully conclusive. There was some evidence that resiliency interventions had a positive effect on hemoglobin A1C levels but not blood pressure. The incorporation of resiliency-oriented interventions into the arsenal of preventing and managing chronic conditions appears to be an opportunity that remains to be better investigated and exploited, and there is need to pursue further understanding of the core components of any intervention that claims to enhance resilience.

Risk of dementia in seniors with newly diagnosed diabetes: a population-based study.

OBJECTIVE: To study whether diabetes onset in late life is a risk factor for dementia. RESEARCH DESIGN AND METHODS: We conducted a population-based matched cohort study using provincial health data from Ontario, Canada. Seniors with (n = 225,045) and without newly diagnosed diabetes (n = 668,070) between April 1995 and March 2007 were followed until March 2012 for a new diagnosis of dementia. Cox proportional hazards modeling was used to compare the risk of dementia between groups after adjusting for baseline cardiovascular disease, chronic kidney disease (CKD), hypertension, and other risk factors. RESULTS: Over this period, we observed 169,114 new cases of dementia. Individuals with diabetes had a modestly higher incidence of dementia (2.68 vs. 2.62 per 100 person-years) than those without diabetes. In the fully adjusted Cox model, the risk of dementia was 16% higher among our subgroup with diabetes (hazard ratio [HR] 1.16 [95% CI 1.15-1.18]). Adjusted HRs for dementia were 1.20 (95% CI 1.17-1.22) and 1.14 (95% CI 1.12-1.16) among men and women, respectively. Among seniors with diabetes, the risk of dementia was greatest in those with prior cerebrovascular disease (HR 2.03; 95% CI 1.88-2.19), peripheral vascular disease (HR 1.47; 95% CI 1.19-1.82), and CKD (HR 1.44; 95% CI 1.38-1.51), and those with one or more hospital visits for hypoglycemia (HR 1.73; 95% CI 1.62-1.84). CONCLUSIONS: In this population-based study, newly diagnosed diabetes was associated with a 16% increase in the risk of dementia among seniors. Preexisting vascular disease and severe hypoglycemia were the greatest risk factors for dementia in seniors with diabetes.
