Impaired striatal glutamate/GABA regulation in violent offenders with antisocial personality disorder and psychopathy.

Men with antisocial personality disorder (ASPD) with or without psychopathy (+/-P) are responsible for most violent crime in society. Development of effective treatments is hindered by poor understanding of the neurochemical underpinnings of the condition. Men with ASPD with and without psychopathy demonstrate impulsive decision-making, associated with striatal abnormalities in functional neuroimaging studies.

Moral Philosophy, Moral Expertise, and the Argument from Disagreement.

Several recent articles have weighed in on the question of whether moral philosophers can be counted as moral experts. One argument denying this has been rejected by both sides of the debate. According to this argument, the extent of disagreement in modern moral philosophy prevents moral philosophers from being classified as moral experts.

Feasibility, acceptability and validity of SMS text messaging for measuring change in depression during a randomised controlled trial.

Background: Despite widespread popularity, text messaging has rarely been used for data collection in clinical research. This paper reports on the development, feasibility, acceptability, validity, and discriminant utility of a single item depression rating scale, delivered weekly via an automated SMS system, as part of a large randomised controlled trial.

Methods: 755 depressed patients (BDI-II score ≥20) were recruited from primary care into a randomised trial of acupuncture versus counselling or usual care, and invited to opt into a repeated-measures text messaging sub-study.

A single-item screening question for fear of recurrence in head and neck cancer.

Fear of recurrence (FoR) is the most frequent concern patients wish to discuss in head and neck review clinics. The aim of the study was to design a simple screening question on fear of recurrence to be incorporated into the University of Washington Quality of Life Questionnaire (UW-QOLv4), for use in clinical practice. A cross-sectional survey comprising 528 patients was conducted.

Electronic reminders did not improve postal questionnaire response rates or response times: a randomized controlled trial.

Objective: We aim to evaluate the effectiveness of electronic reminders (ERs) to improve the response rates and time to response of postal questionnaires in a health research setting.

Study Design And Setting: This pragmatic randomized controlled trial (RCT) was nested within a multicenter RCT of yoga for lower back pain. Participants who provided an electronic mail address and/or mobile phone number were randomized to receive an ER or no reminder (controls) on the day they were due to receive a follow-up questionnaire.

Participants' preference for type of leaflet used to feed back the results of a randomised trial: a survey.

Background: Hundreds of thousands of volunteers take part in medical research, but many will never hear from researchers about what the study revealed. There is a growing demand for the results of randomised trials to be fed back to research participants both for ethical research practice and for ensuring their co-operation in a trial. This study aims to determine participants' preferences for type of leaflet (short versus long) used to summarise the findings of a randomised trial; and to test whether certain characteristics explained participants' preferences.

A randomized trial of electronic reminders showed a reduction in the time to respond to postal questionnaires.

Objective: To assess the effect of electronic reminders (ERs) on response rate and time to response for the return of postal questionnaires.

Study Design And Setting: This open randomized controlled trial (RCT) was conducted at the University of York. Participants who were taking part in an established RCT and who provided an electronic mail address and/or mobile telephone number were eligible to take part in the study.

Protocol for the ProFHER (PROximal Fracture of the Humerus: Evaluation by Randomisation) trial: a pragmatic multi-centre randomised controlled trial of surgical versus non-surgical treatment for proximal fracture of the humerus in adults.

Background: Proximal humeral fractures, which occur mainly in older adults, account for approximately 4 to 5% of all fractures. Approximately 40% of these fractures are displaced fractures involving the surgical neck. Management of this group of fractures is often challenging and the outcome is frequently unsatisfactory.

Using postal randomization to replace telephone randomization had no significant effect on recruitment of patients.

Objective: To test the effect of postal randomization on recruitment of patients into a randomized trial in primary care.

Study Design And Setting: General practices used a telephone service to randomize patients in our trial. Delays in the start of recruitment at some sites led us to modify the randomization procedure.

Improving response rates using a monetary incentive for patient completion of questionnaires: an observational study.

Background: Poor response rates to postal questionnaires can introduce bias and reduce the statistical power of a study. To improve response rates in our trial in primary care we tested the effect of introducing an unconditional direct payment of 5 pounds for the completion of postal questionnaires.

Methods: We recruited patients in general practice with knee problems from sites across the United Kingdom.

The DAMASK trial protocol: a pragmatic randomised trial to evaluate whether GPs should have direct access to MRI for patients with suspected internal derangement of the knee.

Background: Though new technologies like Magnetic Resonance Imaging (MRI) may be accurate, they often diffuse into practice before thorough assessment of their value in diagnosis and management, and of their effects on patient outcome and costs. MRI of the knee is a common investigation despite concern that it is not always appropriate. There is wide variation in general practitioners (GPs) access to, and use of MRI, and in the associated costs.

Fimbria-fornix lesions compromise the induction of long-term potentiation at the Schaffer collateral-CA1 synapse in the rat in vivo.

Although bilateral fimbria-fornix (FF) lesioning impairs spatial performance in animals, the literature is equivocal regarding its effects on hippocampal long-term potentiation (LTP). We examined the effects of FF lesioning on LTP induction in the Schaffer collateral-CA1 pathway in vivo with a protocol that delivered theta burst stimulation (TBS) trains of increasing length until a sufficient length was reached to induce LTP of the monosynaptic field excitatory postsynaptic potential (fEPSP). Experiments were performed in urethan-anesthetized Long-Evans rats either 4 or 12-16 wk after lesioning.
