OBJECTIVE Previous research has suggested that psychosis is better described as a continuum rather than a dichotomous entity. This study aimed to describe the distribution of positive psychosis-like symptoms in the general population by means of latent class analysis. METHOD Latent class analysis was used to identify homogeneous sub-types of(More)
Previous research investigating the etiology of psychosis has identified risk factors such as childhood sexual abuse and cannabis use. This study investigated the multiplicative effect of these variables on clinically assessed diagnoses of psychosis based on a large community sample (the National Comorbidity Survey). Demographic variables (sex, age,(More)
AIM The aim of this review article was to outline current evidence relating to the treatment and prevention of parastomal herniation with a view to guide surgeons dealing with patients potentially affected by this complication. METHOD Medline and PubMed databases were searched using the keywords 'parastomal hernia/herniation', 'stoma hernia/herniation'(More)
UNLABELLED Most patients who undergo surgical procedures experience acute postoperative pain, but evidence suggests that less than half report adequate postoperative pain relief. Many preoperative, intraoperative, and postoperative interventions and management strategies are available for reducing and managing postoperative pain. The American Pain Society,(More)
AIMS To identify population-based clinical and demographic correlates of alcohol use dimensions. METHODS Using data from a population-based sample of Great Britain (n = 7849), structural equation modelling (SEM) was used to identify associations between demographic and clinical variables and two competing dimensional models of the Alcohol Use Disorders(More)
Clinically defined psychosis is recognizable and distinguishable from nonclinical or subclinical psychosis by virtue of its clinical relevance (ie, its associated distress and its need for care and/or treatment). According to the continuum hypothesis, subclinical psychosis is merely quantitatively different from more extreme phenotypic expressions and as(More)
BACKGROUND The development of enterocutaneous fistula (ECF) is one of the most challenging complications encountered in colorectal surgery. Currently, only two supra-regional centres are nationally designated in the United Kingdom to treat ECF patients. The aim of this study was to assess clinical outcome measures following the implementation of an ECF(More)
Exposure to traumatic events has been implicated in the onset and development of a range of psychiatric disorders. People can be exposed to multiple traumatic events and previous research suggests that traumatic experiences may cluster at the individual level. This study aimed to examine the distribution of traumatic experiences in a large nationally(More)
STUDY OBJECTIVE To determine if the use of ultrasound guidance (vs non-ultrasound techniques) improves the success rate of nerve blocks. DESIGN Meta-analysis of randomized controlled trials (RCTs) in the published literature. SETTING University medical center. MEASUREMENTS 16 RCTs of patients undergoing elective surgical procedures were studied.(More)
This study assessed the distribution of posttraumatic stress disorder (PTSD) symptoms and psychosis indicators among a large sample of individuals with a lifetime diagnosis of PTSD. The identification of a psychotic PTSD subtype was also predicted. Using data from the National Comorbidity Survey a latent class analysis was conducted on the PTSD symptoms of(More)
