Parenting Programmes for preventing tobacco, alcohol or drugs misuse in children under 18 : a systematic review

This is a pre-copy-editing, author-produced PDF of an article accepted for publication in Health Education Research following peer review. The definitive publisher-authenticated version [Petrie, J. ,Bunn, F. and Byrne, G. (2007) 'Parenting Programmes for preventing tobacco, alcohol or drug abuse in children under 18:a systematic review'. Health Education Research 22 (2) pp.177-191] is available online at: http://her.oxfordjournals.org/archive/index.dtl --Copyright Oxford University PressWe conducted a systematic review of controlled studies of parenting programmes to prevent tobacco, alcohol or drug abuse in children under 18. We searched Cochrane Central Register of Controlled Trials, specialised Register of Cochrane Drugs and Alcohol Group, Pub Med, psych INFO, CINALH, and SIGLE. Two reviewers independently screened studies, extracted data and assessed study quality. Data were collected on actual or intended use of tobacco, alcohol or drugs by child, and associated risk or antecedent behaviours. Due to heterogeneity we did not pool studies in a meta-analysis and instead present a narrative summary of the findings. Twenty studies met our inclusion criteria. Statistically significant self-reported reductions of alcohol use were found in six of 14 studies, of drugs in five of nine studies and tobacco in nine out of 13 studies. Three interventions reported increases of tobacco, drug and alcohol use. We concluded that parenting programmes can be effective in reducing or preventing substance use. The most effective appeared to be those that shared an emphasis on active parental involvement and on developing skills in social competence, self-regulation and parenting. However, more work is needed to investigate further the change processes involved in such interventions and their long-term effectivenessPeer reviewe

Discriminating between chronic fatigue syndrome and depression: a cognitive analysis

Background: chronic fatigue syndrome (CFS) and depression share a number of common symptoms and the majority of CFS patients meet lifetime criteria for depression. While cognitive factors seem key to the maintenance of CFS and depression, little is known about how the cognitive characteristics differ in the two conditions.Methods: fifty-three CFS patients were compared with 20 depressed patients and 38 healthy controls on perceptions of their health, illness attributions, self-esteem, cognitive distortions of general and somatic events, symptoms of distress and coping. A 6 month follow-up was also conducted to determine the stability of these factors and to investigate whether CFS-related cognitions predict ongoing disability and fatigue in this disorder.Results: between-group analyses confirmed that the depressed group was distinguished by low self-esteem, the propensity to make cognitive distortions across all situations, and to attribute their illness to psychological factors. In contrast, the CFS patients were characterized by low ratings of their current health status, a strong illness identity, external attributions for their illness, and distortions in thinking that were specific to somatic experiences. They were also more likely than depressed patients to cope with their illness by limiting stress and activity levels. These CFS-related cognitions and behaviours were associated with disability and fatigue 6 months later.Conclusions: CFS and depression can be distinguished by unique cognitive styles characteristic of each condition. The documented cognitive profile of the CFS patients provides support for the current cognitive behavioural models of the illness

Do patients with suspected heart failure and preserved left ventricular systolic function suffer from "diastolic heart failure" or from misdiagnosis? A prospective descriptive study

OBJECTIVES: To characterise the clinical features of patients with suspected heart failure but preserved left ventricular systolic function to determine if they have other potential causes for their symptoms rather than being diagnosed with 'diastolic heart failure.' DESIGN: Prospective descriptive study. SETTING: Outpatient based direct access echocardiography service. PARTICIPANTS: 159 consecutive patients with suspected heart failure referred by general practitioners. MAIN OUTCOME MEASURES: Symptoms (including shortness of breath, ankle oedema, and paroxysmal nocturnal dyspnoea) and history of coronary heart disease and chronic pulmonary disease. Transthoracic echocardiography, body mass index, pulmonary function tests, and electrocardiography. RESULTS: 109 of 159 participants had suspected heart failure in the absence of left ventricular systolic dysfunction, valvular heart disease, or atrial fibrillation. Of these 109, 40 were either obese or very obese, 54 had a reduction in forced expiratory volume in 1 second to </=70%, and 97 had a peak expiratory flow rate </=70% of normal. Thirty one patients had a history of angina, 12 had had a myocardial infarction, and seven had undergone a coronary artery bypass graft. Only seven patients lacked a recognised explanation for their symptoms. CONCLUSIONS: For most patients with a diagnosis of heart failure but preserved left ventricular systolic function there is an alternative explanation for their symptoms-for example, obesity, lung disease, and myocardial ischaemia-and the diagnosis of diastolic heart failure is rarely needed. These alternative diagnoses should be rigorously sought and managed accordingly

Diabetes, hypertension, and cardiovascular disease: clinical insights and vascular mechanisms

Hypertension and type 2 diabetes are common comorbidities. Hypertension is twice as frequent in patients with diabetes compared with those who do not have diabetes. Moreover, patients with hypertension often exhibit insulin resistance and are at greater risk of diabetes developing than are normotensive individuals. The major cause of morbidity and mortality in diabetes is cardiovascular disease, which is exacerbated by hypertension. Accordingly, diabetes and hypertension are closely interlinked because of similar risk factors, such as endothelial dysfunction, vascular inflammation, arterial remodelling, atherosclerosis, dyslipidemia, and obesity. There is also substantial overlap in the cardiovascular complications of diabetes and hypertension related primarily to microvascular and macrovascular disease. Common mechanisms, such as upregulation of the renin-angiotensin-aldosterone system, oxidative stress, inflammation, and activation of the immune system likely contribute to the close relationship between diabetes and hypertension. In this article we discuss diabetes and hypertension as comorbidities and discuss the pathophysiological features of vascular complications associated with these conditions. We also highlight some vascular mechanisms that predispose to both conditions, focusing on advanced glycation end products, oxidative stress, inflammation, the immune system, and microRNAs. Finally, we provide some insights into current therapies targeting diabetes and cardiovascular complications and introduce some new agents that may have vasoprotective therapeutic potential in diabetes

Liability of a Trade Union for the Actions of Its Members: A Case for Strict Liabilitv

This article discusses the civil liability of a trade union for the actions of its members. It is submitted that, in view of provisions in the New Brunswick Industrial Relations Act and Judicature Act, such liability should be strictly imposed. This would not unfairly burden the union and would clarify the requirement of pleadings, a difficulty often facing practitioners.Dans cet article, l'auteur examine la question de la responsabilité civile des syndicats du fait des actes de leurs membres et fait valoir qu'il y aurait lieu de les assujettir à un régime de responsabilité stricte au vu des dispositions de la Loi sur les relations industrielles et de la Loi sur l’organisation judiciaire. Un tel régime n'imposerait pas un fardeau excessif aux syndicats et clarifierait les conditions de forme auxquelles doit satisfaire la rédaction des conclusions, tâche qui est souvent source de difficultés pour le practicien dans ce domaine
