The effect of increased fruit and vegetable consumption on blood pressure and lipids: a pooled analysis of six randomised controlled fruit and vegetable intervention trials.

Background: Increasing fruit and vegetable (FV) consumption is associated with reduced cardiovascular disease risk in observational studies but with little evidence from randomised controlled trials (RCTs). The impact of concurrent pharmacological therapy is unknown.

Objective: To pool data from six RCTs to examine the effect of increasing FV intake on blood pressure (BP) and lipid profile, also exploring whether effects differed by medication use.

Association of TGFB1 rs1800469 and BCMO1 rs6564851 with coronary heart disease and IL1B rs16944 with all-cause mortality in men from the Northern Ireland PRIME study.

Background: Historically, high levels of morbidity and mortality have been associated with cardiovascular disease in the Northern Ireland population. Previously reported associations between single nucleotide polymorphisms (SNPs) and cardiovascular disease within other populations have not always been consistent.

Objective: To investigate associations between 33 SNPs with fatal or non-fatal incident coronary heart disease (CHD) events and all-cause mortality in the Northern Irish participants of the Prospective Epidemiological Study of Myocardial Infarction (PRIME).

'Why didn't they see my scars?' Critical thematic analysis of simulated participants' perceived tensions surrounding objective structured clinical examinations.

Background: Simulated participants (SPs) play an important role in simulated assessments of clinical encounters between medical students and patients, most notably in objective structured clinical examinations (OSCEs). SP contributions to OSCEs are invaluable, taking the role of a patient or carer. While SPs in some settings/contexts may rate students, their role has been problematized in the literature for their lack of agency within a standardised format of OSCEs that promotes reliability, objectivity and accountability.

Exercise prescription improves exercise tolerance in young children with CHD: a randomised clinical trial.

Objective: The main objective of this study was to ascertain if a structured intervention programme can improve the biophysical health of young children with congenital heart disease (CHD). The primary end point was an increase in measureable physical activity levels following the intervention.

Methods: Patients aged 5-10 years with CHD were identified and invited to participate.

Mutation Type and a Genetic Risk Score Associate Variably With Brugada Syndrome Phenotype in Families.

Background: Brugada syndrome (BrS) is characterized by the type 1 Brugada ECG pattern. Pathogenic rare variants in (mutations) are identified in 20% of BrS families in whom incomplete penetrance and genotype-negative phenotype-positive individuals are observed. E1784K- is the most common mutation identified.

Periodontitis and risk of prevalent and incident coronary heart disease events.

Objective: To investigate periodontitis as a risk factor for prevalent and incident coronary heart disease (CHD) in a group of middle-aged men from Northern Ireland.

Methods: A representative sample of 1400 dentate men had a comprehensive periodontal examination between 2001 and 2003. Prevalent and incident CHD events were validated by independent cardiologists.

A High Polyphenol Diet Improves Psychological Well-Being: The Polyphenol Intervention Trial (PPhIT).

Mental ill health is currently one of the leading causes of disease burden worldwide. A growing body of data has emerged supporting the role of diet, especially polyphenols, which have anxiolytic and antidepressant-like properties. The aim of the present study was to assess the effect of a high polyphenol diet (HPD) compared to a low polyphenol diet (LPD) on aspects of psychological well-being in the Polyphenol Intervention Trial (PPhIT).

Application of H-NMR Metabolomics for the Discovery of Blood Plasma Biomarkers of a Mediterranean Diet.

The Mediterranean diet (MD) is a dietary pattern well-known for its benefits in disease prevention. Monitoring adherence to the MD could be improved by discovery of novel dietary biomarkers. The MEDiterranean Diet in Northern Ireland (MEDDINI) intervention study monitored the adherence of participants to the MD for up to 12 months.

Enhancing Feedback On Case Reports To Third Year Medical Students On Clinical Attachment.

Preparation of case reports during student attachments has the attraction of reflecting real life clinical practice, but lacks standardisation when used in summative assessment. This study examined the occurrence and nature of feedback after the introduction of a new system of formative case reports in Third Year clinical attachments. Quantitative and qualitative methods were used to compare the new system to previous practice.

Beneficial effect of a polyphenol-rich diet on cardiovascular risk: a randomised control trial.

Objectives: There is previous epidemiological evidence that intake of polyphenol-rich foods has been associated with reduced cardiovascular disease risk. We aimed to investigate the effect of increasing dietary polyphenol intake on microvascular function in hypertensive participants.

Methods: All participants completed a 4-week run-in phase, consuming <2 portions of fruit and vegetables (F&V) daily and avoiding berries and dark chocolate.

Dietary Micronutrient Intake and Micronutrient Status in Patients With Chronic Stable Heart Failure: An Observational Study.

Background: Observational studies suggest that patients with heart failure have a tendency to a reduced status of a number of micronutrients and that this may be associated with an adverse prognosis. A small number of studies also suggest that patients with heart failure may have reduced dietary intake of micronutrients, a possible mechanism for reduced status.

Objective: The aims of this study were to assess dietary micronutrient intake and micronutrient status in a group of patients with heart failure.

Energy compensation in the real world: good compensation for small portions of chocolate and biscuits over short time periods in complicit consumers using commercially available foods.

While investigations using covert food manipulations tend to suggest that individuals are poor at adjusting for previous energy intake, in the real world adults rarely consume foods of which they are ill-informed. This study investigated the impact in fully complicit consumers of consuming commercially available dark chocolate, milk chocolate, sweet biscuits and fruit bars on subsequent appetite. Using a repeated measures design, participants received four small portions (4 × 10-11 g) of either dark chocolate, milk chocolate, sweet biscuits, fruit bars or no food throughout five separate study days (counterbalanced in order), and test meal intake, hunger, liking and acceptability were measured.

The effect of multiple micronutrient supplementation on left ventricular ejection fraction in patients with chronic stable heart failure: a randomized, placebo-controlled trial.

Objectives: This study sought to investigate the effect of a multiple micronutrient supplement on left ventricular ejection fraction (LVEF) in patients with heart failure.

Background: Observational studies suggest that patients with heart failure have reduced intake and lower concentrations of a number of micronutrients. However, there have been very few intervention studies investigating the effect of micronutrient supplementation in patients with heart failure.

Neurophobia among general practice trainees: the evidence, perceived causes and solutions.

Introduction: As general practice (GP) is the main source of referrals to neurologists, neurology education for GP trainees is important. We investigated the existence of neurophobia, contributing factors and potential prevention strategies among GP trainees.

Methods: In a questionnaire survey interest, knowledge, confidence and perceived difficulty in neurology were compared with different medical specialties.

Patient safety and communication: a new assessment for doctors trained in countries where language differs from that of the host country: results of a pilot using a domain-based assessment.

Objective: Global migration of healthcare workers places responsibility on employers to comply with legal employment rights whilst ensuring patient safety remains the central goal. We describe the pilot of a communication assessment designed for doctors who trained and communicated with patients and colleagues in a different language from that of the host country. It is unique in assessing clinical communication without assessing knowledge.

Evaluation of a final year work-shadowing attachment.

The transition from medical student to junior doctor is well recognised to be a difficult and stressful period. To ease this transition, most UK universities have a work-shadowing period (WSP), during which students can learn practical skills needed for forthcoming employment. The aim of this study was to evaluate the WSP at Queen's University Belfast, and gain the views of both students and Foundation Programme Supervisors and Directors (FPSDs).

The role of micronutrients in heart failure.

Heart failure is a common condition in the Western world, particularly among elderly persons and with an ever-aging population, the incidence is expected to increase. Diet in the setting of heart failure is important--patients with this condition are advised to consume a low-salt diet and monitor their weight closely. Nutritional status of patients with heart failure also is important--those with poor nutritional status tend to have a poor long-term prognosis.

Plasma HDL cholesterol and risk of myocardial infarction: a mendelian randomisation study.

Background: High plasma HDL cholesterol is associated with reduced risk of myocardial infarction, but whether this association is causal is unclear. Exploiting the fact that genotypes are randomly assigned at meiosis, are independent of non-genetic confounding, and are unmodified by disease processes, mendelian randomisation can be used to test the hypothesis that the association of a plasma biomarker with disease is causal.

Methods: We performed two mendelian randomisation analyses.
