Admission at the weekend is associated with increased risk of subsequent death within 30 days of admission. The likelihood of death actually occurring is less on a weekend day than on a mid-week day.
Composite outcomes, in which multiple end points are combined, are frequently used as primary outcome measures in randomized trials and are often associated with increased statistical efficiency. However, such measures may prove challenging for the interpretation of results. In this article, we examine the use of composite outcomes in major clinical trials, assess the arguments for and against them, and provide guidance on their application and reporting. To assess incidence and quality of reporting, we systematically reviewed the use of composite end points in clinical trials in An-
Propensity score based methods are used increasingly to evaluate the effectiveness of treatments when evidence from randomised trials is not available. However, users need to be aware of their strengths and limitations
Two sets of molecular descriptors, the five experimental Abraham, and the five COSMOments of Klamt's COSMO-RS, have been compared for a data set of 470 compounds. Both sets are considered as almost complete sets of LFER. The two sets of descriptors are shown to exhibit a large overlap as far as their chemical content. The chemical information however is distributed differently in each set with the Abraham set incorporating extra information in the excess molar refraction descriptor E. Regression equations have been constructed to predict the experimental Abraham descriptors from theoretically calculated COSMOments. The chemical interpretation of these equations is however difficult because of the lack of clustering which characterizes the distribution of chemical information through the two sets of descriptors. The predictability of the regression equations is tested successfully using a reasonably large set of data, and the method is compared to recent attempts to calculate the Abraham descriptors from various theoretical bases.
Background Mild frailty or pre-frailty is common and yet is potentially reversible. Preventing progression to worsening frailty may benefit individuals and lower health/social care costs. However, we know little about effective approaches to preventing frailty progression. Objectives (1) To develop an evidence- and theory-based home-based health promotion intervention for older people with mild frailty. (2) To assess feasibility, costs and acceptability of (i) the intervention and (ii) a full-scale clinical effectiveness and cost-effectiveness randomised controlled trial (RCT). Design Evidence reviews, qualitative studies, intervention development and a feasibility RCT with process evaluation. Intervention development Two systematic reviews (including systematic searches of 14 databases and registries, 1990–2016 and 1980–2014), a state-of-the-art review (from inception to 2015) and policy review identified effective components for our intervention. We collected data on health priorities and potential intervention components from semistructured interviews and focus groups with older people (aged 65–94 years) (n = 44), carers (n = 12) and health/social care professionals (n = 27). These data, and our evidence reviews, fed into development of the ‘HomeHealth’ intervention in collaboration with older people and multidisciplinary stakeholders. ‘HomeHealth’ comprised 3–6 sessions with a support worker trained in behaviour change techniques, communication skills, exercise, nutrition and mood. Participants addressed self-directed independence and well-being goals, supported through education, skills training, enabling individuals to overcome barriers, providing feedback, maximising motivation and promoting habit formation. Feasibility RCT Single-blind RCT, individually randomised to ‘HomeHealth’ or treatment as usual (TAU). Setting Community settings in London and Hertfordshire, UK. Participants A total of 51 community-dwelling adults aged ≥ 65 years with mild frailty. Main outcome measures Feasibility – recruitment, retention, acceptability and intervention costs. Clinical and health economic outcome data at 6 months included functioning, frailty status, well-being, psychological distress, quality of life, capability and NHS and societal service utilisation/costs. Results We successfully recruited to target, with good 6-month retention (94%). Trial procedures were acceptable with minimal missing data. Individual randomisation was feasible. The intervention was acceptable, with good fidelity and modest delivery costs (£307 per patient). A total of 96% of participants identified at least one goal, which were mostly exercise related (73%). We found significantly better functioning (Barthel Index +1.68; p = 0.004), better grip strength (+6.48 kg; p = 0.02), reduced psychological distress (12-item General Health Questionnaire –3.92; p = 0.01) and increased capability-adjusted life-years [+0.017; 95% confidence interval (CI) 0.001 to 0.031] at 6 months in the intervention arm than the TAU arm, with no differences in other outcomes. NHS and carer support costs were variable but, overall, were lower in the intervention arm than the TAU arm. The main limitation was difficulty maintaining outcome assessor blinding. Conclusions Evidence is lacking to inform frailty prevention service design, with no large-scale trials of multidomain interventions. From stakeholder/public perspectives, new frailty prevention services should be personalised and encompass multiple domains, particularly socialising and mobility, and can be delivered by trained non-specialists. Our multicomponent health promotion intervention was acceptable and delivered at modest cost. Our small study shows promise for improving clinical outcomes, including functioning and independence. A full-scale individually RCT is feasible. Future work A large, definitive RCT of the HomeHealth service is warranted.

Objectives To assess the satisfaction of men with their testicular implants after undergoing orchidectomy for testicular cancer, and to determine their reasons for accepting or declining a prosthesis. Patients and methods In all, 424 men who had undergone radical orchidectomy and were part of the testicular cancer follow-up programme were sent an anonymous questionnaire comprising 10 questions covering two main areas. First, the reasons for accepting or declining an implant and second (if they received an implant) their satisfaction with the size, position, feel, shape and overall comfort; 234 men (55%) responded. Results About a third (71 men) accepted an implant, a third declined and a third were not offered the choice. Of the men who replied 91% felt that it was extremely important to be offered an implant at the time of surgery. Of the 71 who received an implant, 19 (27%) were dissatis®ed and felt that they had an average or poor cosmetic result. The reasons for this dissatisfaction are presented and discussed. Conclusions All men undergoing orchidectomy should be offered a testicular implant, irrespective of age.Sample implants in all sizes should be available in the outpatient department. This will give men realistic expectations and allow them to choose a suitable size of implant. The dimensions of the available implants should be improved to create a more elliptical prosthesis, to avoid dissatisfaction with the shape. Adequate ®xation to the base of the scrotum is important to avoid the`high riding' implant.
The increased medicine administration error rate in patients with dysphagia requires healthcare professionals to take extra care when prescribing, dispensing and administering medicines to this group.
