Background

Ischaemic heart disease is the leading cause of global mortality and when accompanied by type 2 diabetes mellitus (T2DM), prognosis is even worse. Lifestyle (LS) interventions are recommended, however, evidence in patients with both chronic ischaemic heart disease (CIHD) and T2DM is scarce. Furthermore, LS interventions were generally performed in a resource intensive supervised setting. Therefore, this study examined whether an individualised telemedically supported home-based LS intervention has a different effect on changes in glycosylated haemoglobin (HbA1c) compared to usual care (UC) in patients with CIHD and T2DM.

Methods

Eligible patients (ICD-10: I20-25; HbA1c≥6.5% or anti-diabetic drugs) were randomly assigned (1:1) to LS or UC at 11 sites. LS intervention consisted of home-based exercise training (ET) and nutritional recommendations following 7-day nutrition diaries. ET was based on the results of a cardiopulmonary exercise test (CPET), i.e. ventilatory thresholds and peak oxygen consumption, and was provided and recorded by a smartphone application. Intensities varied and volume was gradually increased to reach at least 150 min/week. Every 2-4 weeks, patients were contacted by telephone to receive feedback and adjust the training (if necessary). CPETs and nutrition diaries were analysed by a core laboratory, which also provided the feedback to the patients. Primary endpoint was the change in HbA1c after 6 months. Secondary endpoints included change in weight, waist circumference, HDL, LDL, triglycerides and quality of life (QoL). The main analysis included all patients with baseline and follow-up (FU) measures (full analysis). In a per-protocol analysis (PPA), patients randomised to LS who performed less than 2/3 of the scheduled exercise time or filled less than 2 out of 3 nutrition diaries were excluded.

Results

Among 499 enrolled patients (mean age, 68 years; 16% female; mean HbA1c, 6.9%), 402 (81%) completed the 6-month FU. From 201 patients who completed FU in the LS group, 76 (38%) were included in the PPA [81 (40%) adhered to ET, 144 (72%) filled at least 2 nutrition diaries]. In the full analysis, mean change in HbA1c was significantly different between LS and UC (-0.1% [95% CI, -0.2 to 0.0], p=0.04). Furthermore, significant differences were found for changes in weight (p<0.001) and the QoL mental component score (MCS) of the Short-Form-36 questionnaire (p=0.006, Table 1). In the PPA, mean changes in HbA1c (p=0.002), weight (p<0.001), waist circumference (p<0.001), triglycerides (p=0.03) and the QoL MCS (p=0.004) were significantly different between groups (Table 1).

Conclusion

In patients with CIHD and T2DM, a telemedically supported home-based LS intervention significantly reduced HbA1c as compared to UC. However, only in the per-protocol analysis, change in HbA1c met a clinically meaningful difference of 0.3% between groups. Therefore, future studies should aim at increasing adherence to such interventions.

Family Conflict Tendency and ADHD

A lack of perseverance, poor attention, and poorly modulated behaviour are important criteria of Attention Deficit Hyperactive Disorder (ADHD). Instructions often have to be repeated, sometimes even by different family members before a child with ADHD attends and complies. We hypothesised that a child with ADHD might cause less disagreement in families with almost no conflicts. Responses to the Mannheim Parents Interview and teacher's form of the Conners scale completed by families of 15 boys (ages 6 to 12 years), diagnosed with ADHD were compared with those of a matched, healthy control group of 15 boys. Parents completed a form assessing the family's cooperation and child-rearing practices. Having few family conflicts, i.e., almost no Verbal Disagreement may reduce Physical Punishment and Anger and Disregard and augment the Openness to another's needs and, for that reason, have protective effects on children's behaviour modulation.

Features in families of boys with hyperkinetic and emotional disorders

Standardized assessment of a family's characteristics (conflict management, cohesion, etc.) is not used routinely, although these variables may play an important role in the course of psychological disorders in children. The present study investigated differences within the features of families of children with hyperkinetic and emotional disorders. Families of 20 boys diagnosed with Attention Deficit Hyperkinetic Disorder and 20 boys with Emotional Disorder (ages 6-12 years) by giving the Mannheim Parents Interview and the teacher's form of the Conners scale were included for evaluation and compared with a matched, healthy control group of 20 boys. Parents were asked to complete a form assessing the family's characteristics ("Familienklima-Testsystem"), including Cohesion, Expressiveness, Conflict Tendency, Individual Independence, Achievement Orientation, Intellectual-Cultural Orientation, Active-Recreational Orientation, Moral-Religious Emphasis, and Organization. Comparison of groups was made by the Kruskal-Wallis test and Mann-Whitney U test. There are significantly more conflicts in families whose children belong to the two disorder groups. Compared with a matched healthy control group, there is low Expressiveness, Independence, and Cultural and Active-Recreational Orientation in the Emotional Disorder group and a significant lack of Organization and Cohesion in the Attention Deficit Hyperkinetic Disorder group. Altogether there seems to be a significant association of Attention Deficit Hyperkinetic Disorder symptoms with the family's Cohesion and Organization. One implication is that therapists focus their efforts not only on the children with disorders but also on their families.

Family coherence and ADHD

A lack of perseverance, poor attention, and poorly modulated behaviour are important criteria of Attention Deficit Hyperactivity Disorder (ADHD). Instructions often must be repeated, sometimes even by different family members, before a child with ADHD attends and complies. The hyperkinetic child might cause less disruption in families with high coherence. Families of 15 boys (aged 6 to 12 years) diagnosed with ADHD using the Mannheim Parent's Interview and the teacher's form of the Conners scale were compared with a matched healthy control group of 15 boys. Parents completed a form assessing the family's cooperation and childrearing practices. Intrafamilial coherence seems to have little positive association with the family's characteristics, especially for boys with Attention Deficit Hyperactivity Disorder. Low coherence among family members may reduce ADHD symptoms and may have protective effects on children with ADHD.

[Early childhood psychosis versus early childhood autism? Differential diagnosis based on one week observation in an inpatient setting]

We report on the case of a 4-year old child suffering for the past six months from a lingering psychotic development. Several months of outpatient observation did not permit a clear differential diagnosis of either childhood autism or an early psychosis. During a one-week inpatient stay at our hospital recurring productive-psychotic episodes were observed that finally led to the exclusion of the diagnosis of "childhood autism" (ICD-10 F 84.0 (Dilling et al., 1993)) and to the diagnosis of "other disintegrative childhood disorder" (ICD-10: F 84.3 (Dilling et al., 1993)).

Epidemiology of benzodiazepine dependence

The charts of 10,861 patients of the Innsbruck University Department of Psychiatry were evaluated for this study. The patients were in- and outpatients admitted between January 1978 and September 1981. WHO criteria were used for the diagnosis of dependence. 1,743 inpatients and 2,130 outpatients were dependent on psychotropic substances (most of them being alcoholics). 57 (1.1%) resp. 73 (1.3%) suffered from polydrug abuse including benzodiazepines. Only nine inpatients and 21 outpatients were addicted to benzodiazepines only. Details of benzodiazepine dependence are discussed.
