Prevalence of head injury and associated disability in prison populations: a systematic review

Objective: This review systematically assesses literature on the prevalence of head injury (HI) and associated disability in adults in prison. Methods: Searches were carried out using electronic databases (PsycINFO, Cochrane Databases, MEDLINE, EMBASE, Web of Science). Reference lists of 2 meta-analyses were checked for relevant articles. Methods were rated for risk of bias. Results: The 10 studies included report a range in prevalence of HI in prisoners from 25% to 86%. Risk of bias was high overall, probably because a range of HI definitions was used, assessments were often not validated, and samples were not or not evidenced to be representative of the prison population. There was an absence of appropriate population controls from which to compare relative risk of HI in different countries. No study reported the prevalence of disability associated with HI. Conclusion: The wide range in prevalence estimates of HI in prisoners is associated with high risk of bias from study design and methods. Persisting disability associated with HI was not reported and as a result the service need for prisoners with HI is unclear. Future studies should indicate that samples are representative of prison populations, use validated tools and internationally accepted definitions of HI, and link prevalence to persisting disability

New Research by CCD Scanning for Comets and Asteroids

The purpose of Spacewatch is to explore the various populations of small objects within the solar system. Spacewatch provides data for studies of comets and asteroids, finds potential targets for space missions, and provides information on the environmental problem of possible impacts. Moving objects are discovered by scanning the sky with charge-coupled devices (CCDs) on the 0.9-meter Spacewatch Telescope of the University of Arizona on Kitt Peak. Each Spacewatch scan consists of three drift scan passes over an area of sky using a CCD filtered to a bandpass of 0.5-1.0 microns (approximately V+R+I with peak sensitivity at 0.7 micron). The effective exposure time for each pass is 143 seconds multiplied by the secant of the declination. We have been finding some 30,000 new asteroids per year and applying their statistics to the study of the collisional history of the solar system. As of the end of the observing run of Nov. 1997, Spacewatch had found a total of 153 Near-Earth Asteroids (NEAs) and 8 new comets since the project began in the 1980s, and had recovered one lost comet. The total number of NEAs found by Spacewatch big enough to be hazardous if they were to impact the Earth is 36. Spacewatch is also efficient in recovery of known comets and has detected and reported positions for more than 137,000 asteroids, mostly new ones in the main belt, including more than 16,000 asteroids designated by the Minor Planet Center (MPC)

Albumin concentrations are primarily determined by the body cell mass and the systemic inflammatory response in cancer patients with weight loss

The association between hypoalbuminemia and poor prognosis in patients with cancer is well recognized. However, the factors that contribute to the fall in albumin concentrations are not well understood. In the present study, we examined the relationship between circulating albumin concentrations, weight loss, the body cell mass (measured using total body potassium), and the presence of an inflammatory response (measured using C- reactive protein) in male patients (n=40) with advanced lung or gastrointestinal cancer. Albumin concentrations were significantly correlated with the percent ideal body weight (r=0.390, p lt 0.05), extent of reported weight loss (r=-0.492, p lt 0.01), percent predicted total body potassium (adjusted for age, height, and weight, r=0.686, p lt 0.001), and logo C-reactive protein concentrations (r=-0.545, p lt 0.001). On multiple regression analysis, the percent predicted total body potassium and log(10) C-reactive protein concentrations accounted for 63% of the variation in albumin concentrations (r(2) = 0.626, p lt 0.001). The interrelationship between albumin, body cell mass, and the inflammatory response is consistent with the concept that the presence of an ongoing inflammatory response contributes to the progressive loss of these vital protein components of the body and the subsequent death of patients with advanced cancer

Discovery of near-Earth asteroids by CCD scanning

The found near-Earth asteroid are different objects with peculiar orbits. With the new technique of CCD scanning we entered the domain of the smallest, the fastest, and the closest near-Earth asteroids. The results are presented

Knowledge about head injury in police custody staff and implications for training

Head injury is prevalent in prisoners and is associated with offending behaviour. Awareness and assessment of the occurrence and effects of recent head injury is important and should occur at an early stage in the criminal justice system. This study looks at knowledge about detainees with a recent head injury in police custody and considers the implications for training of custody officers. Questionnaires about perceived training needs and knowledge about head injury were completed by 67 custody officers in Scotland. All officers reported a need for further training about head injury and the most common areas of need were perceived to be assessment, early management and long term effects. Knowledge and past training seemed to be more focussed on awareness of potentially catastrophic brain injury and a limited understanding of impairment of insight and of emotional and behavioural effects was evident. There is a need for routine training about recent effects of head injury for custody officers to include the effects on insight, emotional and behavioural effects in detainees in addition to training on catastrophic outcomes which tends to be the main focus of current practice

The prevalence, characteristics, and impact of head injury in female prisoners: a systematic PRISMA review

Background: Although head injury (HI) is associated with offending behavior, there has been relatively little attention to female prisoners. This systematic review considers prevalence and characteristics of females prisoners with HI, with a view towards improving understanding of service needs. Methods: Electronic databases, two meta-analyses and two systematic reviews were searched for relevant papers. Studies describing the prevalence of HI in female prisoners were included and assessed for risk of bias. Results: Twelve studies were included. Prevalence of HI ranged from 19%-95%. It was lower if using hospital records rather than self-report and generally not different by gender. Risk of bias was high overall, with little consistency in assessment methods and definition of HI. Sample sizes of female prisoners with HI were often modest and not clearly representative of the population. The experiences/needs of prisoners can differ by gender, females having a higher risk of physical and mental health problems, including psychological trauma. Conclusion: HI is prevalent in female prisoners, and their needs and experiences may differ from male prisoners with HI and female prisoners without. Future research should address methodological limitations to allow a firm, evidence base for effective services and interventions for female prisoners with HI to be developed

Prisoner knowledge about head injury is improved by brief psychoeducation

Introduction: The high prevalence of head injury (HI) in prisoners and its association with offending indicates a need for interventions. However, there is little evidence and none for the effectiveness of psychoeducation in improving prisoner knowledge about HI and its effects. Methods: Small groups of males in two Scottish prisons underwent a 1 hour psychoeducation session delivered by PowerPoint and combined with question and answer, video clips and a booklet about HI. A pre-post intervention design was used to assess knowledge about HI from vignettes. Participants indicated effects of HI using unprompted free recall and then with a questionnaire (the Symptom Checklist; SCL), pre-education (n = 34), post-education (n = 19) and at 4-week follow-up (n = 11). Free recall was scored using symptom lists from national guidelines (FR-SIGN) or the SCL (FR-SCL). Within-subject comparisons were made between pre-intervention, post-intervention and follow-up scores. Results: Knowledge about HI significantly increased pre- to post-education for FR-SIGN (d = 0.91; 95% CI 0.62, 2.53) and FR-SCL (d = 0.99; 95% CI 0.95, 4.00) without decrement at follow-up (FR-SIGN d = 1.27; 95% CI 0.53, 2.56; FR-SCL r = 0.60). Scores on the SCL did not change over time (p > .05). Conclusion: Prisoner knowledge about HI was improved by brief psychoeducation suitable for delivery in prisons

Head injury and associated disability in adults undergoing pre-sentencing assessment by criminal justice social work

Although evidence indicates that head injury (HI) is prevalent in prisoners, little is known about HI in defendants during the Court process. This study assesses history of HI and persisting sequelae in defendants undergoing Criminal Justice Social Work (CJSW) assessment for Court. A cross sectional, between subjects design was used. HI history was assessed using the Ohio State University TBI Identification-Method and disability with the Glasgow Outcome Scale-Extended in 46 adult defendants undergoing a CJSW assessment in Scotland. Assessments of mental health, cognitive function, effort on tests and dysexecutive behaviour were also carried out. Comparisons were made between defendants with and without significant HI. Significant HI (SHI) was found in 33/46 (72%) participants and 39% (13/33) of these had persisting disability. Those with SHI were more likely to have moderate-severe mental health difficulties, problematic alcohol or drug use and impairment on the Dysexecutive Questionnaire. Group differences were not found on cognitive tests or in offending history. No CJSW report identified HI. Disability, psychological distress, dysexecutive behaviour and potentially harmful substance use are more common in defendants with SHI. Training and a screening process for HI in CJSW assessments is needed to inform Court disposals and interventions
