Psychological predictors of eating pathology in older adult women.

Eating pathology is generally considered to affect females during adolescence and early adulthood. However, in recent years, there has been an increased recognition that disordered eating occurs in middle-aged and elderly women and that the presentation is similar to that of eating disorders in younger women. In the research presented here, results of an Internet survey of older adult women (N = 245; aged 60-90 years) indicate that the factors significantly associated with eating pathology-perfectionism, depression, and sociocultural pressures to be thin-closely parallel those reported for both younger and middle-aged women.

Religiousness and Psychological Distress in Jewish and Christian Older Adults.

OBJECTIVES: In this study, the authors explore how the association between religiousness and psychological distress varies by religious affiliation. Prior work has shown that the association between religious belief and psychological distress is stronger for Christians than Jews, while religious activity is associated with lower psychological distress for both groups. METHODS: Interviews were conducted using a community sample of 143 Christian and Jewish older adults, ages 65 and over. Quantitative measures were used to assess levels of organizational and intrinsic religiosity, as well as symptoms of depression and anxiety. RESULTS: Christians who are highly involved in the organizational aspects of their religion report fewer depressive symptoms than Jews who have high levels of organizational religiosity, and the opposite is the case at lower levels of organizational religiosity. No significant group differences were found in the relationship between religiousness and anxiety. CONCLUSIONS: The results of this study indicate a difference between Jews and Christians in the reasons that they turn to their respective religious services, particularly in late life.

Assessment of the TASER XREP blunt impact and penetration injury potential using cadaveric testing.

TASER International's extended range electronic projectile (XREP) is intended to be fired from a shotgun, impact a threat, and apply remote neuromuscular incapacitation. This study investigated the corresponding potential of blunt impact injury and penetration. Forty-three XREP rounds were deployed onto two male human cadaver torsos at impact velocities between 70.6 and 95.9 m/sec (232 and 315 ft/sec). In 42 of the 43 shots fired, the XREP did not penetrate the abdominal wall, resulting in superficial wounds only. On one shot, the XREP's nose section separated prematurely in flight, resulting in penetration. No bony fractures were observed with any of the shots. The viscous criterion (VC), blunt criterion (BC), and energy density (E/A) were calculated (all nonpenetrating tests, average ± 1 standard deviation: VC: 1.14 ± 0.94 m/sec, BC: 0.77 ± 0.15, E/A: 22.6 ± 4.15 J/cm(2)) and, despite the lack of injuries, were generally found to be greater than published tolerance values.

Religiosity, authoritarianism, and attitudes toward psychotherapy in later life.

OBJECTIVE: This study explores whether intrinsic religiosity in older adults is associated with attitudes toward psychotherapy (perceived need, stigma tolerance, interpersonal openness, and confidence in mental health practitioners) when controlling for authoritarianism. METHOD: Interviews were conducted with a sample of 307 community-residing adults aged 65­82. Data were collected from 164 Black and 142 White older adults about their intrinsic religiosity, authoritarianism, and mental health help-seeking attitudes. RESULTS: Intrinsic religiosity was associated with stigma tolerance and interpersonal openness after controlling for authoritarianism. CONCLUSION: Intrinsic religiosity and authoritarianism appear to be independently related to psychotherapy attitudes. Religious older adults may prefer to seek help in religious contexts, while the association of authoritarianism to less favorable psychotherapy attitudes toward psychotherapy may be explained by a fear of external perspectives. Results on the whole reinforce the importance of including religiousness and authoritarianism in models of mental health help-seeking.

Basic principles of magnetic resonance imaging.

Magnetic resonance (MR) imaging has become the dominant clinical imaging modality with widespread, primarily noninvasive, applicability throughout the body and across many disease processes. The flexibility of MR imaging enables the development of purpose-built optimized applications. Concurrent developments in digital image processing, microprocessor power, storage, and computer-aided design have spurred and enabled further growth in capability. Although MR imaging may be viewed as "mature" in some respects, the field is rich with new proposals and applications that hold great promise for future research health care uses. This article delineates the basic principles of MR imaging and illuminates specific applications.

Effective gene therapy for an inherited CNS disease in a large animal model.

Genetic diseases affecting the brain typically have widespread lesions that require global correction. Lysosomal storage diseases are good candidates for central nervous system gene therapy, because active enzyme from genetically corrected cells can be secreted and taken up by surrounding diseased cells, and only small amounts of enzyme (<5% of normal) are required to reverse storage lesions. Injection of gene transfer vectors into multiple sites in the mouse brain has been shown to mediate widespread reversal of storage lesions in several disease models. To study a brain closer in size to the human brain, we evaluated the extent of storage correction mediated by a limited number of adeno-associated virus vector injections in the cat model of human alpha-mannosidosis. The treated cats showed remarkable improvements in clinical neurological signs and in brain myelination assessed by quantitative magnetic resonance imaging. Postmortem examination showed that storage lesions were greatly reduced throughout the brain, even though gene transfer was limited to the areas surrounding the injection tracks. The data demonstrate that widespread improvement of neuropathology in a large mammalian brain can be achieved using multiple injection sites during one operation and suggest that this could be an effective treatment for the central nervous system component of human lysosomal enzyme deficiencies.

Magnetization transfer ratio histogram analysis of normal-appearing gray matter and normal-appearing white matter in multiple sclerosis.

PURPOSE: The purpose of this work was to determine the extent of disease and disease severity in the conventional MR normal-appearing gray matter (NAGM) and white matter (NAWM) in patients with relapsing-remitting (RR) and secondary progressive (SP) multiple sclerosis (MS) utilizing quantitative magnetization transfer ratio (MTR) histogram analysis. METHOD: Twenty-seven patients with MS (16 RR, 11 SP) and 16 healthy control subjects were studied. MTR was calculated in the totally segmented GM and WM without T2 lesions in each group. RESULTS: Each of the RR and SP MS patient groups had significantly smaller MTR histogram mean values in NAGM and NAWM than the healthy subjects (p
