Type 2 Diabetes Mellitus and Cognitive Performance in a Population-Based Sample of the Oldest Old: Impact of Comorbid Dementia

We examined the relationship between type 2 diabetes mellitus and cognitive function in a population-based sample of very old people. The sample comprised 338 persons, aged 80-93 years (mean age 83.5 years), of whom 70 persons had type 2 diabetes mellitus. Measures of cognitive functioning included tests of perceptual speed, visuo-spatial ability, inductive reasoning, short-term memory, semantic memory, episodic memory, and the Mini-Mental State Examination. Regression analyses showed that type 2 diabetes mellitus duration was related to test performance across all cognitive domains, with the exception of short-term memory, such that longer duration was associated with lower test performance. When cases with dementia were excluded from the sample, further analyses showed that diabetes duration was not associated with cognitive test performance. This indicates that diabetes is not related to lower cognitive function in the general population of non-demented old people. Diabetes, however, increases the risk for cerebrovascular incidents, like stroke, that may contribute to vascular dementia.

Glycosylated hemoglobin and psychological adjustment in adolescents with diabetes

The relationships between glycosylated hemoglobin levels as an index of metabolic control, life events occurring in the previous year, and general adjustment in the areas of attitude towards diabetes, independence, peer, school, and family relationships were investigated in 37 adolescents with insulin-dependent diabetes mellitus. The number or type of life events did not show a relationship with metabolic control. As measured by the Sullivan Diabetic Adjustment Scale, diabetic adolescents who were in better metabolic control reported more conflict regarding family relationships and issues of independence than did those in lesser control.     

2型糖尿病一级亲属代谢相关指标分布规律的研究

为了研究2型糖尿病(DM)家系一级亲属的代谢相关指标变化规律,选择55个2型糖尿病家系中糖尿病患者的一级亲属为研究对象,按照糖耐量试验结果分组,比较组间血压、血糖、血脂、C肽、胰岛素等指标。结果显示,2型糖尿病家系一级亲属各组血脂水平的变化差异无显著性,而血糖、胰岛素抵抗等指标差异有显著性。由此得出结论,2型DM家系一级亲属血脂、血糖、血压、胰岛素等指标均有一定程度的异常,且各组间的血糖、血压、胰岛素抵抗等差异显著于血脂水平的变化。     

肺结核患者的血糖控制

肺结核与糖尿病是两种严重危害人类健康的疾病。越来越多的研究证明,发生结核病的一个重要的危险因素为糖尿病,而且可能会影响肺结核患者的表现和治疗反应。另外,结核病可能会导致糖耐量异常,并使糖尿病患者的血糖控制不良。糖尿病引起肺结核发病增加,可能是因为持续的高血糖损害了针对结核杆菌的机体免疫。对结核病患者合并糖尿病者,药物治疗需考虑到药物动力学,监测血糖,谨慎用药。     

Preliminary report: psychological assessment of Greek women with diabetes during pregnancy

23 Greek pregnant women with type 1 diabetes had a higher mean score on the Maudsley Obsessive-Compulsive Inventory in the second and third trimesters of pregnancy than 13 women with gestational diabetes. Long-term changes in the lifestyle of the former may apparently lead to this higher mean. For those with gestational diabetes, higher scores of alexithymia were correlated with slightly worse glycemic control.     

Type A Behavior and Diabetic Control: Implications of Psychological Reactance for Health Outcomes1

According to laboratory research, Type A coronary-prone individuals are sensitive to threats to their personal control and react to such threats with active and often stressful coping responses. The present investigation tested the prediction that these features of Type A behavior would interfere with blood glucose regulation in insulin-dependent diabetes mellitus patients. Two independent hypotheses were investigated. Because elevated sympathetic arousal, a concomitant of stressful coping, is associated with elevated glucose levels, it was predicted that Type A diabetics experiencing high levels of life stress would display poorest blood glucose control (indexed by Hemoglobin A₁c). The second hypothesis was derived from the observation that Type As are more likely than Type Bs to respond to control threats with reactance in order to restore the perception of control. Given that illness or treatment can reduce personal control, it was predicted that Type A diabetics would be most reactant and, thus, most medically noncompliant. To test these hypotheses, 37 Type 1 diabetics were assessed for Type A behavior, life change, attributional style, desire for control (both within treatment and in general), and specific perceptions of and actions to their diabetes. Type As were more likely than Type Bs to show poor blood glucose control. However, for patients in general, and Type As in particular, blood glucose regulation was not related to life stress. Rather, those Type As who displayed poor glucose control made more extreme self-attributions about the cause of their diabetes, were angrier about it, and felt they should fight it. The implications of these findings for a reactance-Type A model of medical compliance are discussed.     

Cognitive functioning and cortisol profiles in first episode major depression

Major Depressive Disorder (MDD) is often associated with high levels of stress and disturbances in the Hypothalamic Pituitary Adrenal (HPA) system, yielding high levels of cortisol, in addition to cognitive dysfunction. Previous studies have shown a relationship between cortisol profile and cognitive functioning in recurrent MDD in general. More specifically, the association between hypercortisolism and cognitive functioning, such as memory and Executive Functioning (EF), and also more recently cortisol suppression has been explored. However, no studies have investigated these relationships in patients diagnosed with first episode MDD. The aim of the present study was to examine the relationship between cortisol levels before and after the Dexamethasone suppression test (DST) and cognitive function in first episode MDD patients. Twenty‐one patients meeting the DSM‐IV criteria for a first episode of MDD diagnosis were included in the study. The control group was matched for age, gender and education level. Cortisol was measured in saliva collected with Salivette sampling devices. Saliva samples were collected 4 times during a 24 hours period over two consecutive days: at awakening, after 45 minutes, after 7 hours and at 11 pm. Dexamethasone (1.0 mg) was given orally on Day 1 at 11 pm. The neuropsychological test battery consisted of standardized tests measuring executive functioning (EF) and memory functioning. Cortisol levels did not differ significantly between patients and controls on Day 1, except for the last sample before Dexamethasone administration, where the control group showed higher levels. Both groups showed suppression after Dexamethasone. On Day 2 there was a significant difference between groups at the third sample, showing a significantly lower level in the control group, suggesting that the controls have a more effective suppression profile than the patients. There were no significant correlations between cortisol levels before or after Dexamethasone and cognitive measures. The results indicate impairment on HPA‐axis functioning in first episode MDD patients, with less suppression functioning compared to healthy controls, but no relationship between cortisol profile and cognitive functioning in EF or Memory.     

Effectiveness of Family Systems Theory Interventions on Adolescents with Type 1 Diabetes: A Meta-analysis

The purpose of this review is to synthesize the evidence and determine the efficacy of interventions based on family systems theory in diabetes-related family conflict, self-management, and glycemic control among adolescents with type 1 diabetes. A systematic search of five English databases was conducted. Interventions based on family systems theory in adolescents with type 1 diabetes that reported diabetes-related family conflict, self-management, and glycemic control as outcome variables were included. A total of 14 articles from ten interventions were included. Meta-analysis results revealed that, compared to adolescents who received usual care, adolescents who received family systems theory interventions reported fewer diabetes-related family conflicts with a medium effect size of 0.32 (p?<?0.05), but there was no significant improvement on self-management or glycemic control (p?>?0.05). Family systems theory interventions appear to have beneficial effect on reducing diabetes-related family conflicts for adolescents with type 1 diabetes. Adolescents who have type 1 diabetes and their families may need multidimensional psychosocial programs accompanied by diabetes education to improve glycemic control.

     

Grip and load force control and coordination in individuals with diabetes in different manipulation tasks

The study aimed to investigate the control and coordination of grip force (normal component) and load force (tangential component) in three different manipulation tasks in individuals with diabetes with and with no diagnosis of diabetic peripheral neuropathy (DPN) and healthy controls. Twenty-four individuals with type 2 diabetes mellitus, 12 with no (nDPN) and 12 with DPN (wDPN), and 12 healthy controls performed three manipulation tasks (static holding, lifting and holding, and oscillation) with the dominant hand, using an instrumented handle. Relative safety margin (% of GF exerted above the minimum GF needed to hold the object) was measured in all tasks. Individuals with diabetes from the nDPN and wDPN groups set lower relative safety margin than controls only in the static holding task. No other group effect was revealed, except a lower coefficient of friction between skin and object surface in individuals with DPN. The coordination between grip and load force and grip force control was not affected by the diabetes during dynamic manipulation tasks (lifting and holding and oscillation). However, when individuals with diabetes without and with DPN performed a manipulation task in which the inflow of cutaneous information was small and stable (static holding), grip force control was affected by the disease. This finding indicates that individuals with type 2 diabetes mellitus not diagnosed with DPN, already show mild impairments in the nervous system that could affect grip force control and that could be one of the first signs of neuropathy caused by the diabetes.     

Feasibility of Pairing Behavioral Activation With Exercise for Women With Type 2 Diabetes and Depression: The Get It Study Pilot Randomized Controlled Trial

Major depressive disorder is often comorbid with diabetes and associated with worse glycemic control. Exercise improves glycemic control and depression, and thus could be a parsimonious intervention for patients with comorbid diabetes and major depression. Because patients with diabetes and comorbid depression are often sedentary and lack motivation to exercise, we developed a group exercise intervention that integrates strategies from behavioral activation therapy for depression to increase motivation for and enjoyment of exercise. We conducted a 6-month pilot randomized controlled trial to test the feasibility of the behavioral activation exercise intervention (EX) for women with diabetes and depression. Of the 715 individuals who contacted us about the study, 29 participants were randomized to the EX condition or an enhanced usual care condition (EUC), which represents 4.1% of participants who initially contacted us. Inclusion criteria made recruitment challenging and limits the feasibility of recruiting women with diabetes and depression for a larger trial of the intervention. Retention was 96.5% and 86.2% at 3 and 6 months. Participants reported high treatment acceptability; use of behavioral activation strategies and exercise class attendance was acceptable. No condition differences were observed for glycemic control, depressive symptoms, and physical activity, though depressive symptoms and self-reported physical activity improved over time. Compared to participants in the EUC condition, participants in the EX condition reported greater exercise enjoyment and no increase in avoidance behavior over time. Using behavioral activation strategies to increase exercise is feasible in a group exercise setting. However, whether these strategies can be delivered in a less intensive manner to a broader population of sedentary adults, for greater initiation and maintenance of physical activity, deserves further study.     

伴家族史的2型糖尿病危险因素的病例对照研究

为探讨2型糖尿病代谢特征及发病的危险因素,选取大连地区91例有家族史的T2DM患者为病例组,以44例患者的配偶（糖耐量正常）为对照组,进行流行病学问卷调查和体格检查,同时测定空腹血糖、空腹胰岛素、总胆固醇、甘油三酯、高密度脂蛋白、低密度脂蛋白等指标,采用稳态模型法计算两组的胰岛素抵抗指数和β细胞功能指数,并进行多因素非条件Logistic回归分析。结果显示：TG、腰臀比和Ln（HOMAIR）病例组高于对照组,而Ln（HOMAβ）则病例组低于对照组,均具有统计学意义（P〈0．05）。多因素非条件Logistic回归分析结果提示,影响T2DM发病的因素有心血管疾病史、Ln（HOMAIR）及Ln（HOMAβ）。由此可见T2DM患者存在血脂代谢异常;心血管疾病史和Ln（HOMAIR）为发病的危险因素,Ln（HOMAβ）为保护因素。     

Factors Associated with Recruitment and Retention in Randomized Controlled Trials of Behavioral Interventions for Patients with Pediatric Type 1 Diabetes

The purpose of this study is to describe recruitment and retention experiences from three behavioral randomized controlled trials conducted among youth with type 1 diabetes. Eligibility, recruitment, and retention data were examined. Study-specific differential study participation and loss-to-follow-up analyses assessed the relations of patient characteristics with treatment completion and 6-month retention. Multivariable logistic regression identified factors independently associated with 6-month retention among all participants. Approximately 70–92 % of randomized participants completed treatment and 58–90 % were retained for follow-up. Older patients and non-Caucasian patients were less likely to enroll. Treatment completion and 6-month retention were less likely among youth who were older, had worse baseline glycemic control, lower household income, and/or unmarried parents. Some subgroups of patients are less likely to participate in research and are more susceptible to loss-to-follow-up. More work is needed to understand the facilitators and barriers to research participation.     

Near-death experiences and the temporal lobe

Abstract— Many studies in humans suggest that altered temporal lobe functioning, especially functioning in the right temporal lobe, is involved in mystical and religious experiences. We investigated temporal lobe functioning in individuals who reported having transcendental "near-death experiences" during life-threatening events. These individuals were found to have more temporal lobe epileptiform electroencephalographic activity than control subjects and also reported significantly more temporal lobe epileptic symptoms. Contrary to predictions, epileptiform activity was nearly completely lateralized to the left hemisphere. The near-death experience was not associated with dysfunctional stress reactions such as dissociation, posttraumatic stress disorder, and substance abuse, but rather was associated with positive coping styles. Additional analyses revealed that near-death experiencers had altered sleep patterns, specifically, a shorter duration of sleep and delayed REM sleep relative to the control group. These results suggest that altered temporal lobe functioning may be involved in the near-death experience and that individuals who have had such experiences are physiologically distinct from the general population.     

Personality – a resource or risk for successful development

Personality as a resource or risk for development was discussed in the light of the results of the ongoing Finnish Jyväskylä Longitudinal Study of Personality and Social Development (FJYLS) which the author has conducted since 1968 when the participants (N = 369, b. 1959) were 8 years of age. A general hypothesis presented within a two‐dimensional framework of self‐control and activity was that the child’s high self‐control of emotions and behavior would be associated with adaptive behavior in adulthood. The results have provided evidence in support for and limitations to the hypothesis. High self‐control was a resource and low self‐control was a risk for development, but there were gender differences that came out consistently in variable‐oriented and person‐oriented analyses. A resource factor for male adult social functioning was, compared to females, a broader construct of self‐control in childhood covering both more passive (compliant) and active (constructive) behavior; only active well‐controlled (constructive) behavior was a resource for female functioning. A risk factor for female functioning was low self‐control combined with passivity (internalizing behavior), whereas low self‐control combined with activity (externalizing behavior) was a risk factor for male functioning. Childhood self‐control was not directly associated with adult psychological functioning such as well‐being but indirectly through social functioning such as career development. Low self‐control in childhood was an antecedent of criminal behavior but only for those male offenders who committed offences in adulthood, not for those who had limited their offending to adolescence.     

Relationship beliefs and illness appraisals are differentially associated with specific ways of coping in spouses of patients with type 2 diabetes

Using data from 117 spouses of patients diagnosed with type 2 diabetes and multiple-group path analysis, the current study explored the association of four relationship beliefs (satisfaction, sacrifice, confidence and instability) and four diabetes appraisals (consequences, distress, control and efficacy) with illness-specific coping behaviour: active engagement, protective buffering and overprotection. The potential moderating effect of gender was also tested. Results indicated gender did moderate the associations among the variables in the model, with the association of relationship satisfaction and active engagement being significantly stronger for men, while diabetes control was more strongly related to protective buffering for women. The only variables associated with active engagement were three relationship-specific cognitions: higher levels of relationship satisfaction (for men only), satisfaction with sacrifice and relationship confidence were all related to higher active engagement. The diabetes appraisals were the only variables associated with protective buffering and overprotection. Higher diabetes distress and diabetes control (for women only) and lower diabetes efficacy were predictive of greater protective buffering. Lower diabetes efficacy and higher diabetes control were associated with greater overprotection. Implications for theory, research and practice are discussed.     

Person–Situation Interaction in Adaptive Emotional Functioning

Two studies applied a person–situation model to examine the effect of emotional affordances of situations. Participants rated their emotional functioning as more extensive in situations classified as being high in emotional affordance than those classified as low in emotional affordance. Participants who scored higher on the individual difference characteristic of emotional intelligence were more interested in entering high emotional affordance situations than were individuals lower in emotional intelligence, and participants who scored higher on emotional intelligence were rated by others as being more successful in high emotional affordance situations than individuals lower in emotional intelligence. These results provide preliminary evidence that the interaction between emotional intelligence and situations may influence emotional functioning.     

Anorexia nervosa in association with diabetes mellitus--a cognitive-behavioural approach to treatment

A case of anorexia nervosa occurring in a patient with diabetes mellitus is reported. The patient was successfully managed using a cognitive-behavioural treatment approach. The presence of diabetes necessitated certain modifications to the standard cognitive-behavioural treatment for anorexia nervosa, including self-monitoring of diabetic regimen behaviours, attention to the adequacy of glycaemic control, and advice about changes in insulin dosage. Cognitive restructuring techniques also had to address diabetes-related thoughts. The general applicability and cost-effectiveness of this type of approach for the treatment of patients with co-existing eating disorders and diabetes is discussed.     

Adverse Childhood Experiences and Diabetes in Adulthood: Support for a Collaborative Approach to Primary Care

Prior studies have demonstrated an association between retrospective reports of experiencing trauma in childhood and the current incidence of type 2 diabetes in adulthood. Much less is known about this association among low-income minority patients in primary care settings. We replicated the adverse childhood experiences (ACEs) Centers for disease control and prevention (CDC) study with a low-income minority sample of primary care patients (N = 801) at a community-based healthcare center. We conducted a cross-sectional retrospective quantitative survey study to examine the association between participants’ reports of past childhood trauma and their current health care outcomes. Data were analyzed using binary logistic regression to evaluate the hypothesis that low income minority patients who reported more childhood trauma (abuse, neglect, household dysfunction, cumulative adverse childhood experiences [ACEs]) would more likely be diagnosed with type 2 diabetes. Results suggest that the number of ACEs in our sample were considerably higher than the original CDC ACEs study, as almost 50 % of patients surveyed at our clinic reported 4 or more ACEs, confirming that trauma is central in our urban primary care setting. The results of the cumulative ACEs score was in the expected direction and was significant, suggesting that participants who cumulatively reported experiencing more childhood trauma were more likely to be diagnosed with type 2 diabetes in adulthood. These findings have implications for family therapists, primary care providers, researchers, and policy makers to develop more collaborative approaches to primary care that better target the negative sequelae of ACEs.
