The role of salt intake and salt sensitivity in the management of hypertension in South Asian people with chronic kidney disease: A randomized controlled trial

Background The effectiveness of salt restriction to lower blood pressure (BP) in Bangladeshi patients with chronic kidney disease (CKD) is uncertain. Objective To test the hypothesis that a tailored intervention intended to reduce salt intake in addition to standard care will achieve a greater reduction in BP in UK Bangladeshi patients with CKD than standard care alone. Design A randomised parallel-group controlled trial conducted over a 6 month period. Setting A tertiary renal unit based in acute care hospital in East London. Participants 56 adult participants of Bangladeshi origin with CKD and BP >130/80 mm Hg or on antihypertensive medication. Intervention Participants were randomly allocated to receive a tailored low-salt diet or the standard low-salt advice. BP medication, physical activity and weight were monitored. Main outcome measures The primary outcome was change in ambulatory BP. Adherence to dietary advice was assessed by measurement of 24 h urinary salt excretion. Results Of 56 participants randomised, six withdrew at the start of the study. During the study, one intervention group participant died, one control group participant moved to Bangladesh. Data were available for the primary endpoint on 48 participants. Compared with control group the intervention urinary sodium excretion fell from 260 mmol/d to 103 mmol/d (131 to 76, p<0.001) at 6 months and resulted in mean (95% CI) falls in 24 h systolic/diastolic BP of 8 mm Hg (11 to 5)/2 (?4 to 2) both p<0.001. Conclusions A tailored intervention can achieve moderate salt restriction in patients with CKD, resulting in clinically meaningful falls in BP independent of hypertensive medication

Spiritual and religious interventions for well-being of adults in the terminal phase of disease

Being ill and near to the end of life can raise questions such as "Why me? Why now?". The experience may start or increase thoughts of a spiritual or religious nature. Some research has found that having spiritual or religious awareness, or both, may help a person cope with disease and dying. We conducted our review through searches for studies that were randomised controlled trials. We only included such studies if they evaluated an intervention that involved a spiritual or religious aspect, such as prayer and meditation, and aimed to support adults in the terminal phase of a disease. We found five studies. In total, the studies involved 1130 participants. Two studies evaluated meditation. Three evaluated the work of a palliative care team that involved physicians, nurses and chaplains. Studies compared those who received the intervention with those who did not. Studies evaluated the interventions in various ways including whether it helped in any way a person's quality of life. There was inconclusive evidence that meditation and palliative care teams that involve a chaplain or spiritual counsellor help patients feel emotionally supported. The findings of the review are limited. This is because none of the studies measured whether the intervention helped the person cope with the disease process, and also it is unclear whether all participants receiving the palliative care team interventions were offered support from a chaplain. All the studies were undertaken in one country, making it difficult to draw conclusions as to whether the intervention would work elsewhere

Changes in volume, clinical practice and outcome after reorganisation of oesophago-gastric cancer care in England: A longitudinal observational study.

AIM: The centralisation of oesophago-gastric (O-G) cancer services in England was recommended in 2001, partly because of evidence for a volume-outcome effect for patients having surgery. This study investigated the changes in surgical services for O-G cancer and postoperative mortality since centralisation. METHODS: Patients with O-G cancer who had an oesophageal or gastric resection between April 2003 and March 2014 were identified in the national Hospital Episodes Statistics database. We derived information on the number of NHS trusts performing surgery, their surgical volume, and the number of consultants operating. Postoperative mortality was measured at 30 days, 90 days and 1 year. Logistic regression was used to examine how surgical outcomes were related to patient characteristics and organisational variables. RESULTS: During this period, 29 205 patients underwent an oesophagectomy or gastrectomy. The number of NHS trusts performing surgery decreased from 113 in 2003-04 to 43 in 2013-14, and the median annual surgical volume in NHS trusts rose from 21 to 55 patients. The annual 30 day, 90 day and 1 year mortality decreased from 7.4%, 11.3% and 29.7% in 2003-04 to 2.5%, 4.6% and 19.8% in 2013-14, respectively. There was no evidence that high-risk patients were not undergoing surgery. Changes in NHS trust volume explained only a small proportion of the observed fall in mortality. CONCLUSION: Centralisation of surgical services for O-G cancer in England has resulted in lower postoperative mortality. This cannot be explained by increased volume alone

Incidence of cardiovascular events after kidney transplantation and cardiovascular risk scores: study protocol

<p>Abstract</p> <p>Background</p> <p>Cardiovascular disease (CVD) is the major cause of death after renal transplantation. Not only conventional CVD risk factors, but also transplant-specific risk factors can influence the development of CVD in kidney transplant recipients.</p> <p>The main objective of this study will be to determine the incidence of post-transplant CVD after renal transplantation and related factors. A secondary objective will be to examine the ability of standard cardiovascular risk scores (Framingham, Regicor, SCORE, and DORICA) to predict post-transplantation cardiovascular events in renal transplant recipients, and to develop a new score for predicting the risk of CVD after kidney transplantation.</p> <p>Methods/Design</p> <p>Observational prospective cohort study of all kidney transplant recipients in the A Coruña Hospital (Spain) in the period 1981-2008 (2059 transplants corresponding to 1794 patients).</p> <p>The variables included will be: donor and recipient characteristics, chronic kidney disease-related risk factors, pre-transplant and post-transplant cardiovascular risk factors, routine biochemistry, and immunosuppressive, antihypertensive and lipid-lowering treatment. The events studied in the follow-up will be: patient and graft survival, acute rejection episodes and cardiovascular events (myocardial infarction, invasive coronary artery therapy, cerebral vascular events, new-onset angina, congestive heart failure, rhythm disturbances and peripheral vascular disease).</p> <p>Four cardiovascular risk scores were calculated at the time of transplantation: the Framingham score, the European Systematic Coronary Risk Evaluation (SCORE) equation, and the REGICOR (Registre Gironí del COR (Gerona Heart Registry)), and DORICA (Dyslipidemia, Obesity, and Cardiovascular Risk) functions.</p> <p>The cumulative incidence of cardiovascular events will be analyzed by competing risk survival methods. The clinical relevance of different variables will be calculated using the ARR (Absolute Risk Reduction), RRR (Relative Risk Reduction) and NNT (Number Needed to Treat).</p> <p>The ability of different cardiovascular risk scores to predict cardiovascular events will be analyzed by using the c index and the area under ROC curves. Based on the competing risks analysis, a nomogram to predict the probability of cardiovascular events after kidney transplantation will be developed.</p> <p>Discussion</p> <p>This study will make it possible to determine the post-transplant incidence of cardiovascular events in a large cohort of renal transplant recipients in Spain, to confirm the relationship between traditional and transplant-specific cardiovascular risk factors and CVD, and to develop a score to predict the risk of CVD in these patients.</p

Influence of surgical rate on patients' reported clinical need and outcomes in English NHS.

BACKGROUND: To determine if higher rates of surgery are associated with lower levels of need (patients' pre-operative reports of their symptoms, functional status and quality of life) and with less benefit (patients' post-operative reports). METHODS: Patient-reported outcome measures (PROMs) collected before and after joint replacement, hernia repair or varicose vein (VV) surgery in National Health Service (NHS)-funded patients (2009/11). Regression analysis for associations between 10% increase in rates and mean PROM score for Primary Care Trust (PCT) populations. RESULTS: National rate for hip and knee replacement increased by 6%, unchanged for hernia repair and decreased by 26% for VV surgery. Changes in PCT rates varied but had little or no association with the mean level of need of patients: 10% increase in the rate was associated with only 0.3% decline in the pre-operative PROM score for knee replacement (P < 0.05) and VV surgery (P < 0.001) and no significant change for other procedures. There was no significant association between a 10% change in the rate and the amount of benefit from surgery apart from a slight reduction (0.46%; P < 0.001) in the disease-specific PROM score for VV surgery. CONCLUSION: Policies by commissioners to reduce surgical rates in the English NHS cannot be justified on the grounds of avoiding inappropriate operations or increasing cost-utility

Brachytherapy in the Palliation of Oesophageal Cancer: Effective but Impractical?

Dysphagia in people with advanced oesophageal cancer can be treated by oesophageal stents, external beam radiotherapy (EBRT) and intraluminal brachytherapy. Despite guidelines recommending brachytherapy for patients with a predicted life expectancy exceeding 3 months, its uptake in the UK has been limited. Here we examine the strength of the evidence supporting the use of brachytherapy compared with oesophageal stents and EBRT and possible reasons for its limited uptake. Trials and observational studies suggest brachytherapy alone confers a benefit to patients, but its impact is less immediate than oesophageal stents; the evidence on effectiveness and value-for-money is limited. Moreover, stronger evidence will probably be insufficient to increase uptake, due to the extra complexity of delivery compared with stents and EBRT and a lack of experience among specialists
