Doctors increasingly rely on medical apps running on smart phones or tablet computers to support their work. However, these apps vary hugely in the quality of their data input screens, internal data processing, the methods used to handle sensitive patient data and how they communicate their output to the user. Inspired by Donabedian's approach to assessing quality and the principles of good user interface design, the Royal College of Physicians' Health Informatics Unit has developed and piloted an 18-item checklist to help clinicians assess the structure, functions and impact of medical apps. Use of this checklist should help clinicians to feel more confident about using medical apps themselves, about recommending them to their staff or prescribing them for patients.

The Royal College of Physicians' FallSafe care bundles constitute measures of good practice, some of which are recommended for all patients, some are additional measures for older and more vulnerable patients admitted to hospital, and there is another bundle for after an inpatient fall, to reduce the number of inpatient falls. In 2013 a dedicated healthcare assistant, trained by the falls team, started a monthly spot audit looking at preventative measures, on all inpatients on every ward of the trust. Monthly results were fed back to the ward managers, ward falls liaison nurses, doctors, therapists and pharmacy staff on each ward, to discuss at the monthly ward governance meetings. ⋯ Compliance with the measures recommended by the FallSafe care bundles has improved following regular spot audit and training. This has led to an overall reduction in the number of inpatient falls. Despite this however, in the real world of changing patient demographics, ward closures and the increasing use of ambulatory care, the number of falls/1,000 bed days has increased.

Sarcopenia and frailty are important conditions that become increasingly prevalent with age. Sarcopenia is the loss of muscle mass and function, and frailty can be defined as multi-system impairment associated with increased vulnerability to stressors. There is overlap between the two conditions, especially in terms of the physical aspects of the frailty phenotype: low grip strength, gait speed and muscle mass. ⋯ In terms of intervention, there is evidence for the benefit of resistance exercise programmes, although these may not always be feasible. Considerable research into the use of medicines, both existing and new, as well as dietary supplements is ongoing. Finally in order to prevent or delay the development of these conditions, an additional approach is to consider aetiological factors operating across the life course.

Since the advent of modern molecular tools, researchers have extensively shown that essential cellular machineries have robust circadian (roughly 24 hours) variations in their pace. This molecular rhythmicity translates directly into time-of-day-dependent variation in physiology in most organ systems, which in turn provides the mechanistic rationale for why timing on a daily basis should matter in many aspects of human health. ⋯ Therefore, it has not been clear how physicians should incorporate knowledge of natural 24-hour rhythms into routine practice. This review is a brief summary of results from recently completed clinical studies on hypertension, myocardial infarction, diabetes mellitus, and adrenal dysfunction that highlights new evidence for the emerging importance of circadian rhythms in diagnosis, prognosis and treatment of disease.

Case Reports
Lesson of the month 2: Non-uraemic calciphylaxis - an unexpected differential diagnosis for a necrotic ulcer.
Calciphylaxis is an uncommon cause of skin necrosis seen almost exclusively in patients with end-stage renal disease. We present an unexpected diagnosis of calciphylaxis in a patient with normal renal and parathyroid function. The patient presented with a month-long history of painful bilateral necrotic leg ulcers, resistant to conventional treatment. ⋯ A biopsy confirmed a diagnosis of calciphylaxis. We suspect that warfarin therapy may have contributed to the development of this condition. Through this case we aim to raise awareness of calciphylaxis as a differential diagnosis of non-healing necrotic skin ulcers, especially in patients with known risk factors including established warfarin therapy.
