Background: A high proportion of patients do not regain outdoor mobility after hip fracture. Rehabilitation explicitly targeting outdoor mobility is needed to enable these older adults to recover activities which they value most. The overarching aim of this study is to determine the feasibility of a randomised controlled trial which aims to assess the clinical- and cost-effectiveness of an intervention designed to enable recovery of outdoor mobility among older adults after hip fracture (the OUTDOOR intervention).

Walking 2 weeks after surgery (early weight-bearing) might be a safe and preferable rehabilitation strategy. This study aimed to determine the clinical and cost effectiveness of an early weight-bearing strategy compared with a delayed weight-bearing strategy.

The aim of the trial is to determine whether extending the radiotherapy field to cover the para-aortic lymph nodes (up to L1/L2 vertebral interspace) can improve outcomes for this patient group.

In the proposed process, carbon dioxide is fixed into ethanol using either chemical catalysis or microbial carbon fixation, and the ethanol created is used as a carbon source for yeast to synthesize food for human or animal consumption. The process depends upon technologies that can utilize electrical energy to fix carbon into ethanol and uses an optimized strain of the yeast to produce high-quality, food-grade, single-cell protein using ethanol as the sole carbon source in a minimal medium.

Counter to this dominant paradigm, the viral eukaryogenesis (VE) hypothesis proposes that the eukaryotes originated as an emergent superorganism and thus did not evolve from LUCA descent with incremental modification. According to the VE hypothesis, the eukaryotic nucleus descends from a viral factory, the mitochondrion descends from an enslaved alpha-proteobacteria and the cytoplasm and plasma membrane descend from an archaeal host.

This research explored the induction and training of PPI Contributors joining trial oversight committees and was used to update the Medical Research Council Clinical Trials Unit at University College London's (MRC CTU at UCL) induction pack for new PPI Contributors.
Methods: Published and unpublished materials provided by other CTUs and research organisations on training for PPI Contributors on oversight committees were reviewed, with themes then triangulated to identify the most common topics covered in induction training.
The defining feature of the eukaryotic cell is the possession of a nucleus that uncouples transcription from translation. According to the updated Viral Eukaryogenesis (VE) hypothesis presented here, the eukaryotic nucleus descends from the viral factory of a DNA virus that infected the archaeal ancestor of the eukaryotes. The VE hypothesis implies that many unique features of the nucleus, including the mechanisms by which the eukaryotic nucleus uncouples transcription from translation, should be viral rather than cellular in origin.

Recent policy documents position engineering as a way to broaden participation for students in STEM fields. However, a recent review of the literature on engineering education found that fewer than 1% of reviewed articles focused on issues of equity and broadening participation. For this reason, there are few frameworks to build on when designing for equitable engineering instruction in K-12 settings.

Design/setting: A national (UK) research priority setting partnership.
Participants: People aged 50 and over who have experienced a fracture of the upper limb, carers involved in their care, family and friends of patients, healthcare professionals involved in the treatment of these patients.
Objective: To determine research priorities in fragility fractures of the lower limb and pelvis which represent the shared priorities of patients, their friends and families, carers and healthcare professionals.
Design/setting: A national (UK) research priority setting partnership.
Participants: Patients over 60 years of age who have experienced a fragility fracture of the lower limb or pelvis; carers involved in their care (both in and out of hospital); family and friends of patients; healthcare professionals involved in the treatment of these patients including but not limited to surgeons, anaesthetists, paramedics, nurses, general practitioners, physicians, physiotherapists and occupational therapists.
Background: Bowling overs are the primary recorded measure for workloads in cricket for youth through to professionals. However, the validity of this measure has never been tested. Additionally, despite the cognitive component of cricket being suggested to be very high, changes in psychomotor processing speed has again not been explored.

A retropharyngeal haemorrhage (RH) is a rare condition that without prompt recognition and management may result in fatal complications. We report a case of RH in a 67-year-old man anticoagulated with rivaroxaban for atrial fibrillation.

We explored researchers' and PPI contributors' accounts of PPI activity and training to inform the design of PPI training for both parties.
Methods: We used semi-structured qualitative interviews with researchers (chief investigators and trial managers) and PPI contributors, accessed through a cohort of clinical trials, which had been funded between 2006 and 2010.
A 29-year-old man, a known epileptic, presented to an accident and emergency department following a tonic-clonic seizure, suffering a second seizure in the department. Subsequently, he reported neck pain, swelling and stiffness. An otorhinolaryngology neck examination revealed a tender left side with two palpable masses and a reduced range of movement.

Decisions made by professional researchers at the outset may go on to have a significant impact on the potential for PPI contributions.
Objective: To increase knowledge of PPI within the early development of RCTs by systematically describing the reported level, nature and acceptability of proposed PPI to the funders.
Background: Many funding bodies require researchers to actively involve service users in research to improve relevance, accountability and quality. Current guidance to researchers mainly discusses general principles. Formal guidance about how to involve service users operationally in the conduct of trials is lacking.
