Systemic Family Therapy for Families who have Experienced Trauma: A Randomised Controlled Trial

This paper describes a randomised controlled trial (RCT) investigation of the added value of systemic family therapy (SFT) over individually focused cognitive behavioural therapy (CBT) for families in which one or more members has suffered trauma and been referred to a community-based psychotherapy centre. The results illustrate how an apparently robust design can be confounded by high attrition rates, low average number of therapeutic sessions and poor protocol adherence. The paper highlights a number of general and specific lessons regarding the resources and processes involved that can act as a model for those planning to undertake studies of this type and scope. A key message is that the challenges of conducting RCTs in ‘real world’ settings should not be underestimated. The wider implications in relation to the place of RCTs within the creation of the evidence base for complex psycho-social interventions is discussed and the current movement towards a phased mixed-methods approach, including the appropriate use of RCTs, which some might argue is a return to the original vision of evidence-based practice (EBP), is affirmed.

Multiple superoxide dismutase 1/splicing factor serine alanine 15 variants are associated with the development and progression of diabetic nephropathy:the Diabetes Control and Complications Trial/Epidemiology of Diabetes Interventions and Complications Genetics study

Despite familial clustering of nephropathy and retinopathy severity in type 1 diabetes, few gene variants have been consistently associated with these outcomes.

Effect of lycopene supplementation on insulin-like growth factor-1 and insulin-like growth factor binding protein-3: a double-blind, placebo-controlled trial

Objective: Studies have suggested a link between lycopene and insulin-like growth factor-1 ( IGF-1). The aim of this study was to test the effect of lycopene supplementation on IGF-1 and binding protein-3 ( IGFBP-3) status in healthy male volunteers.

The MATISSE study: a randomised trial of group art therapy for people with schizophrenia

Background: Art Therapy has been promoted as a means of helping people who may find it difficult to express themselves verbally engage in psychological treatment. Group Art Therapy has been widely used as an adjunctive treatment for people with schizophrenia but there have been few attempts to examine its effects and cost effectiveness has not been examined. The MATISSE study aims to evaluate the clinical and cost effectiveness of group Art Therapy for people with schizophrenia.

Accuracy of Death Certificates in COPD: Analysis from the TORCH Trial

The Towards a Revolution in COPD Health (TORCH) trial was an international clinical trial of chronic obstructive pulmonary disease (COPD) patients where cause of death was assigned by an independent committee. Comparison of death certificate data and adjudicated cause of death allows a unique opportunity to determine death certificate accuracy and frequency of COPD listing on death certificates of COPD patients. In this analysis, the authors determine the concordance between adjudicated cause of death and primary and secondary cause of death from death certificates. In 317 (80%) of informative deaths, the primary or secondary cause of death from certificates agreed with adjudicated cause of death. Only 229 (58%) of death certificates in these COPD patients listed COPD on the certificate. COPD was not listed on the death certificate in 21% of deaths adjudicated to be caused by COPD exacerbation. Compared with pulmonary causes, the listing of COPD on certificates occurred with less frequency than cardiovascular, cancer and other categories of death. The combined primary and secondary listing on death certificates has good concordance with actual cause of death. COPD is under-reported on death certificates, and this under-reporting is more frequent when the primary cause of death is not pulmonary.

Dietary intake of fruits and vegetables improves microvascular function in hypertensive subjects in a dose-dependent manner

Background— Observational evidence has consistently linked increased fruit and vegetable consumption with reduced cardiovascular morbidity; however, there is little direct trial evidence to support the concept that fruit and vegetable consumption improves vascular function. This study assessed the dose-dependent effects of a fruit and vegetable intervention on arterial health in subjects with hypertension.

Methods and Results— After a 4-week run-in period during which fruit and vegetable intake was limited to 1 portion per day, participants were randomized to consume either 1, 3, or 6 portions daily for the next 8 weeks. Endothelium-dependent and -independent arterial vasodilator responses were assessed by venous occlusion plethysmography in the brachial circulation before and after intervention. Compliance was monitored with serial contemporaneous 4-day food records and by measuring concentrations of circulating dietary biomarkers. A total of 117 volunteers completed the 12-week study. Participants in the 1-, 3-, and 6-portions/d groups reported consuming on average 1.1, 3.2, and 5.6 portions of fruit and vegetables, respectively, and serum concentrations of lutein and ß-cryptoxanthin increased across the groups in a dose-dependent manner. For each 1-portion increase in reported fruit and vegetable consumption, there was a 6.2% improvement in forearm blood flow responses to intra-arterial administration of the endothelium-dependent vasodilator acetylcholine (P=0.03). There was no association between increased fruit and vegetable consumption and vasodilator responses to sodium nitroprusside, an endothelium-independent vasodilator.

Conclusions— The present study illustrates that among hypertensive volunteers, increased fruit and vegetable consumption produces significant improvements in an established marker of endothelial function and cardiovascular prognosis.
