Behavioural counselling to increase consumption of fruit and vegetables in low income adults : randomised trial

Objective To measure the effect of brief behavioural counselling in general practice on patients’ consumption of fruit and vegetables in adults from a low income population. Design Parallel group randomised controlled trial. Setting Primary health centre in a deprived, ethnically mixed inner city area. Participants 271 patients aged 18-70 years without serious illness. Intervention Brief individual behavioural counselling based on the stage of change model; time matched nutrition education counselling. Main outcome measures Self reported number of portions of fruit and vegetables eaten per day, plasma β carotene, α tocopherol, and ascorbic acid concentrations, and 24 hour urinary potassium excretion. Assessment at baseline, eight weeks, and 12 months. Results Consumption of fruit and vegetables increased from baseline to 12 months by 1.5 and 0.9 portions per day in the behavioural and nutrition groups (mean difference 0.6 portions, 95% confidence interval 0.1 to 1.1). The proportion of participants eating five or more portions a day increased by 42% and 27% in the two groups (mean difference 15%, 3% to 28%). Plasma β carotene and α tocopherol concentrations increased in both groups, but the rise in β carotene was greater in the behavioural group (mean difference 0.16 μmol/l, 0.001 μmol/l to 1.34 μmol/l). There were no changes in plasma ascorbic acid concentrations or urinary potassium excretion. Differences were maintained when analysis was restricted to the 177 participants with incomes ≤ £400 (€596, $640) a week. Conclusions Brief individual counselling in primary care can elicit sustained increases in consumption of fruit and vegetables in low income adults in the general population

Fear of dying and inflammation following acute coronary syndrome

Aims Many patients are afraid of dying during acute coronary syndrome (ACS), but the origins and biological correlates of these emotional responses are poorly understood. This study evaluated the prevalence of fear of dying, associations with inflammatory responses during ACS, and later heart rate variability (HRV) and cortisol secretion. Methods and results Two hundred and eight patients admitted with clinically verified ACS rated their fear of dying on interview in hospital. Plasma tumour necrosis factor (TNF)α was recorded on admission, and HRV and salivary cortisol were assessed 3 weeks later. Intense distress and fear of dying was experienced by 21.7%, with moderate levels in 66.1% patients. Fear of dying was more common in younger, lower socioeconomic status, and unmarried patients. It was positively associated with plasma TNFα on admission after controlling for sociodemographic factors, clinical risk, and pain intensity (adjusted odds = 4.67, 95% C.I. 1.66-12.65). TNFα was associated with reduced HRV 3 weeks later, adjusting for clinical and sociodemographic factors and medication (P = 0.019), while fear of dying was associated with reduced cortisol output (P = 0.004). Conclusions Intense distress and fear of dying and heightened inflammation may be related manifestations of an acute biobehavioural response to severe cardiac injury, and have implications for prognostically significant biological risk processe

Feasibility study to assess the effect of a brief mindfulness intervention for patients with chronic obstructive pulmonary disease: A randomized controlled trial

Psychological distress is common among patients with chronic obstructive pulmonary disease (COPD). This study aimed to assess whether a 10-minute mindfulness intervention reduces distress and breathlessness, improves mood and increases mindfulness among hospital inpatients following acute exacerbation of COPD.Fifty patients were recruited following an acute admission. The immediate effects of a 10-minute mindfulness-based body scan were compared with a control intervention. Participants were randomized to receive either a mindfulness-based body scan (n = 24) or a control condition (n = 26) via a 10-minute audio recording. Participants completed a self-assessment survey, including the Borg scale for breathlessness, Philadelphia Mindfulness Scale and Hospital Anxiety and Depression Scale. They then completed six brief single item measures of dyspnoea, anxiety, depression, happiness, stress and mindfulness before and after the intervention daily for three consecutive days. Acceptability was rated according to ‘usefulness’ and whether they would recommend the intervention to other patients. Results showed that there was a tendency for change in most outcomes, but no significant differences between the groups. Most participants rated the intervention as useful and would recommend it. Existing knowledge of mindfulness interventions among these patients is very limited and this study may be helpful in the development of other brief interventions. © The Author(s) 2018

Pilot randomised controlled trial of a brief mindfulness-based intervention for those with persistent pain

A pilot-randomised controlled trial (RCT) examined the effects of a brief mindfulness-based intervention (MBI) on persistent pain patients and assessed the feasibility of conducting a definitive RCT. A brief (15 min) mindfulness body-scan audio was compared with an active control administered in a clinic and then used independently over 1 month. Immediate effects of the intervention were assessed with brief measures of pain severity, distraction and distress. Assessments at baseline, 1 week and 1 month included pain severity and interference, mood, pain-catastrophizing, mindfulness, self-efficacy, quality of life and intervention acceptability. Of 220 referred patients, 147 were randomised and 71 completed all assessments. There were no significant immediate intervention effects. There were significant positive effects for ratings of intervention ‘usefulness’ at 1 week (p = 0.044), and pain self-efficacy at 1 month (p = 0.039) for the MBI group compared with control. Evidently, it is feasible to recruit persistent pain patients to a brief MBI study. Strategies are needed to maximise retention of participants

Pilot study evaluating a brief mindfulness intervention for those with chronic pain: study protocol for a randomized controlled trial.

BACKGROUND: The burden of chronic pain is a major challenge, impacting the quality of life of patients. Intensive programmes of mindfulness-based therapy can help patients to cope with chronic pain but can be time consuming and require a trained specialist to implement. The self-management model of care is now integral to the care of patients with chronic pain; home-based interventions can be very acceptable, making a compelling argument for investigating brief, self-management interventions. The aim of this study is two-fold: to assess the immediate effects of a brief self-help mindfulness intervention for coping with chronic pain and to assess the feasibility of conducting a definitive randomized controlled trial to determine the effectiveness of such an intervention. METHODS/DESIGN: A randomized controlled pilot study will be conducted to evaluate a brief mindfulness intervention for those with chronic pain. Ninety chronic pain patients who attend hospital outpatient clinics will be recruited and allocated randomly to either the control or treatment group on a 1:1 basis using the computer-generated list of random numbers. The treatment group receives mindfulness audios and the control group receives audios of readings from a non-fiction book, all of which are 15 minutes in length. Immediate effects of the intervention are assessed with brief psychological measures immediately before and after audio use. Mindfulness, mood, health-related quality of life, pain catastrophizing and experience of the intervention are assessed with standardized measures, brief ratings and brief telephone follow-ups, at baseline and after one week and one month. Feasibility is assessed by estimation of effect sizes for outcomes, patient adherence and experience, and appraisal of resource allocation in provision of the intervention. DISCUSSION: This trial will assess whether a brief mindfulness-based intervention is effective for immediately reducing perceived distress and pain with the side effect of increasing relaxation in chronic pain patients and will determine the feasibility of conducting a definitive randomized controlled trial. Patient recruitment began in January 2015 and is due to be completed in June 2016. TRIAL REGISTRATION: ISRCTN61538090 Registered 20 April 2015

Cortisol awakening response is elevated in acute coronary syndrome patients with type-D personality.

Abstract Objective: Type-D or bdistressedQ personality and depression following admission for acute coronary syndrome (ACS) have been associated with poor clinical outcome. The biological pathways underpinning this relationship may include disruption of the hypothalamic-pituitary-adrenocortical (HPA) axis. We therefore assessed cortisol output in patients who had recently suffered from ACS. Method: Salivary cortisol was assessed eight times over a 24-h period in 72 patients within 5 days of admission for ACS. Depressive symptoms were measured with the Beck Depression Inventory (BDI), and type-D personality was measured with the Type-D Scale-16. Particular attention was given to cortisol awakening response (CAR), which was measured as the difference in cortisol between waking and peak responses 15-30 min later. Results: Cortisol showed a typical diurnal pattern, with low levels in the evening, high levels early in the day, and CAR averaging 7.58F10.0 nmol/l. Cortisol was not related to the severity of ACS or underlying coronary artery disease or to BDI scores. The CAR was positively associated with type-D personality independently of age, gender, and body mass ( P=.007). Linear regression showed that type-D personality accounted for 7.9% of the variance in CAR after age, sex, body mass, BDI, cortisol level on waking, and fatigue had been taken into account ( P=.008). Conclusions: Type-D personality may be associated with disruption of HPA axis function in survivors of acute cardiac events and may contribute to heightened inflammatory responses influencing future cardiac morbidity.

Intentional and unintentional non-adherence to medications following an acute coronary syndrome: A longitudinal study

Objective Non-adherence to medication is common among coronary heart disease patients. Non-adherence to medication may be either intentional or unintentional. In this analysis we provide estimates of intentional and unintentional non-adherence in the year following an acute coronary syndrome (ACS). Method In this descriptive prospective observational study of patients with confirmed ACS medication adherence measures were derived from responses to the Medication Adherence Report Scale at approximately 2 weeks (n = 223), 6 months (n = 139) and 12 months (n = 136) following discharge from acute treatment for ACS. Results Total medication non-adherence was 20%, 54% and 53% at each of these time points respectively. The corresponding figures for intentional non-adherence were 8%, 15% and 15% and 15%, 52% and 53% for unintentional non-adherence. There were significant increases in the levels of medication non-adherence between the immediate discharge period (2 weeks) and 6 months that appeared to stabilize between 6 and 12 months after acute treatment for ACS. Conclusion Unintentional non-adherence to medications may be the primary form of non-adherence in the year following ACS. Interventions delivered early in the post-discharge period may prevent the relatively high levels of non-adherence that appear to become established by 6 months following an ACS
