Primary liver cancer consists of distinct subtypes with differing aetiology so it is valuable to study the incidence of these subtypes separately. This study aims to investigate time and socio-economic deprivation trends in the incidence of primary liver cancer subtypes in England, identifying the burden in the population. ⋯ Liver cell carcinoma and intrahepatic bile duct carcinoma incidence increased between 1990 and 2009 in both sexes. This pattern was largely driven by patients living in the most deprived areas. Differences observed may be due to the variation in the prevalence of known risk factors such as chronic hepatitis B and C viral infections and excessive alcohol consumption.

Classification of patients with back pain in order to inform treatments is a long-standing aim in medicine. We used latent class analysis (LCA) to classify patients with low back pain and investigate whether different classes responded differently to a cognitive behavioural intervention. The objective was to provide additional guidance on the use of cognitive behavioural therapy to both patients and clinicians. ⋯ We were able to classify the trial participants based on psychosocial baseline scores relevant to the intervention. An association between class membership and outcome was identified for those people receiving the intervention, but not those in the control group. However, we were not able to identify outcome associations for individual classes and so predict outcome in order to aid clinical decision making. For this cohort of patients, the STarT system was as successful, but not superior.

In the context of an ageing population, increasing numbers of older people with long-term conditions are presenting to secondary health care facilities in the United Kingdom having experienced a fall or fall-related injury. Despite such observations, falls and long-term conditions have traditionally been regarded as entirely separate entities. The purpose of this study was to explore the process of behaviour change in a small sample of older people with the fall-associated chronic liver disease primary biliary cirrhosis (PBC) receiving either a standard or an enhanced programme of strength and balance training (SBT). ⋯ Longer, but not necessarily more intensive, periods of clinical intervention are necessary to support individuals at risk of falling to move through the incremental stages of behaviour change. Effective self-management support should focus on the development of a wide range of strategies and behaviours to empower older people with long-term conditions develop an ongoing active commitment to SBT.

Pressure ulcers (PUs) are a common and serious complication in critically ill patients. The aim of this study was to evaluate the relationship between the development of a PU and hospital mortality in patients requiring mechanical ventilation (MV) in an intensive care unit (ICU). ⋯ Within the limitations of a single-centre approach, PU development appears to be associated with an increase in mortality among patients requiring MV for 24 hours or longer.

Randomized Controlled Trial
Experimental studies to improve the reliability and validity of regulatory judgments on health care in the Netherlands: a randomized controlled trial and before and after case study.
We examined the effect of two interventions on both the reliability and validity of regulatory judgments: adjusting the regulatory instrument and attending a consensus meeting. ⋯ Participating in a consensus meeting improved reliability and validity. Increasing the number of inspectors resulted in both higher reliability and validity values. Organizing consensus meetings and increasing the number of inspectors per regulatory visit seem to be valuable interventions for improving regulatory judgments.
