Emotional processing and bulimic psychopathology: age as a factor among nonclinical women

OBJECTIVES: This study tested the hypothesis that bulimic attitudes are associated with both attentional bias toward and cognitive avoidance of emotion cues among nonclinical women, considering whether the same pattern was found across early adulthood. METHOD: Eighty nonclinical women were divided into younger (< or =21 years) and older (> or =22 years) age groups. Each completed the Bulimic Investigatory Test and a Stroop task, designed to determine biases in the processing of negative and positive emotional information. RESULTS: Among the older women, more bulimic attitudes were associated with a specific attentional bias toward negatively valenced emotional material. In contrast, the younger women with more severe bulimic attitudes showed greater cognitive avoidance of both positive and negative emotion cues. DISCUSSION: These findings suggest that women with bulimic attitudes differ with age in their processing of emotional information. Potential implications are considered for clinical work with bulimic women of different ages.     

Rehabilitation and outcome after severe head injury.

After severe head injury, many children continue to experience major cognitive and behavioural problems and consequent educational difficulties, even after good physical recovery. Forty three children referred to the regional multidisciplinary head injury rehabilitation team are described. The clinical outcome at a median interval of 13 months after injury showed that 18 (42%) had persistent neurological impairment and 15 (35%) had an identified need for special educational support. Thirty seven children were further assessed for psychiatric morbidity, cognitive impairment, and classroom performance. Rutter behavioural questionnaires were sent to parents and teachers of head injured index cases and classmate controls matched for age and sex. Index parents scored their children significantly worse in both 'health' and 'habits' and more cases than controls had scores suggesting a psychiatric disorder. Teachers scored index cases significantly worse for five of the traits questioned, but discriminated cases from controls less decisively than parents. Index cases were significantly disadvantaged on teachers' assessments of classroom skills and performance. A need for improved support and training of staff who teach head injured children was identified.     

Political economy of tobacco control in low-income and middle-income countries: lessons from Thailand and Zimbabwe. Global Analysis Project Team

Crucial to the success of the proposed Framework Convention on Tobacco Control will be an understanding of the political and economic context for tobacco control policies, particularly in low-income and middle-income countries. Policy studies in Thailand and Zimbabwe employed the analytical perspective of political economy and a research strategy that used political mapping, a technique for characterizing and evaluating the political environment surrounding a policy issue, and stakeholder analysis, which seeks to identify key actors and to determine their capacity to shape policy outcomes. These policy studies clearly revealed how tobacco control in low-income and middle-income countries is also being shaped by developments in the global and regional political economy. Hence efforts to strengthen national control policies need to be set within the context of globalization and the international context. Besides the transnational tobacco companies, international tobacco groups and foreign governments, international agencies and nongovernmental organizations are also playing influential roles. It cannot be assumed, therefore, that the tobacco control strategies being implemented in industrialized countries will be just as effective and appropriate when implemented in developing countries. There is an urgent need to expand the number of such tobacco policy studies, particularly in low-income and middle-income countries. Comprehensive guidelines for tobacco policy analysis and research are required to support this process, as is a broader international strategy to coordinate further tobacco policy research studies at country, regional and global levels.     

Validity of esophageal pressure measurements with positive end-expiratory pressure in preterm infants

Previous research suggested that esophageal pressure changes (DeltaP(es)) may not reflect pleural pressure changes (DeltaP(pl)) in the presence of positive end-expiratory pressure (PEEP), making assessments of dynamic lung mechanics invalid in these circumstances. To test this hypothesis, we measured DeltaP(es) using a water-filled catheter in 18 preterm infants with lung disease (9 intubated), and adjusted the catheter position to achieve a valid occlusion test. End-expiratory occlusions were then carried out at PEEP (cm H(2)O) of 0, 4, and 8, and plots of DeltaP(es) against DeltaP(ao) during airway occlusion were examined to derive the ratio DeltaP(es)/DeltaP(ao) and the r value (as a measure of linearity). There was no significant change in DeltaP(es)/DeltaP(ao), which remained close to 1.0 as PEEP was increased from 0 to 8 cm H(2)O, and r also remained close to unity, indicating no appreciable hysteresis or alinearity of the plots. Our results show that DeltaP(es), when measured with an appropriately placed water-filled catheter, continues to reflect DeltaP(pl) accurately when lung volume is raised by applying PEEP up to 8 cm H(2)O.     

The experience of caring for older people with dementia in a rural area: using services

This paper reports findings from the carer component of the Gwynedd Dementia Study. It is based on carer interviews, using quantitative and qualitative data. It confirms earlier findings that carers for people with dementia are typically female and older than other carers, although it notes that caring husbands are amongst the oldest carers. The problems that are most common are those that cause psychological stress to carers. Carers were found to receive both help and appreciation from their families and to perceive neighbours to be helpful if needed. In Gwynedd, as elsewhere, levels of formal service inputs are low, but most of the carers appeared to receive the services they needed. Problems are primarily associated with crisis support and long-term care is accepted reluctantly. It is suggested that community care dementia specialists could play a supporting role for carers.     

Eating in space--from an astronaut's perspective

Food systems and meal components are constantly under review and development at the National Aerospace and Space Administration. The goal of this work is to generate a diet that meets the nutrient requirements of astronauts and satiates them. The constraints involved in shorter- and longer-term missions are described. The insight provided by observations of astronauts from the Skylab and Shuttle eras will allow researchers to consider the fact that, for any nutritional regimen to work, it must consider the limitations and taste buds of the individuals involved. Otherwise, the best diet design generated by their work may never be consumed.     

Currarino triad: Characteristic appearances on magnetic resonance imaging and plain radiography

The Currarino triad is a complex anomaly consisting of an anorectal malformation, a sacral bone defect and a presacral mass. It was first described in 1981 and since then, approximately 250 cases have been reported. Radiology has an important part to play in the diagnosis of this entity, as the imaging features are characteristic. We report a case of Currarino triad in an infant who presented with intractable constipation and discuss relevant MRI and plain radiography findings.
