Evidence exists that fluctuating levels of sex hormones affect interhemispheric interaction in women during the menstrual cycle. The present study investigated whether interhemispheric interaction is susceptible to direct hormonal manipulations via hormone therapy (HT). Sixty-eight postmenopausal women who received HT either with estrogen alone (n = 15), an estrogen-gestagen combination (n = 22) or without HT (n = 31) were investigated. Participants were asked to match letters according to their physical or name identity. Matches were presented either within or across visual half-fields. Additionally, a simple reaction time task, assumed to estimate interhemispheric transfer time (IHTT), was used. Overall, postmenopausal women showed an across-field advantage in the more demanding name-identity task but not in the less demanding physical-identity task. However, across both tasks, the groups differed in responses to within- and across-field trials: the control group performed better on across- than within-field trials, whereas both HT groups showed faster responses on within- than across-field trials. IHTT did not differ between groups. The findings suggest that postmenopausal estrogen-therapy affects the relative efficiency of interhemispheric integration by modulating within-hemisphere functioning.

The current article examines the effect of administering dehydroepiandrosterone (DHEA) on visual-spatial performance in postmenopausal women (N = 24, ages 55–80). The concurrent reduction of serum DHEA levels and visual-spatial performance in this population, coupled with the documented effects of DHEA's androgenic metabolites on visual-spatial performance, suggests that DHEA administration may enhance visual-spatial performance. The current experiment used a double-blind, placebo-controlled crossover design in which 50 mg of oral DHEA was administered daily in the drug condition to explore this hypothesis. Performance on the Mental Rotation, Subject-Ordered Pointing, Fragmented Picture Identification, Perceptual Identification, Same-Different Judgment, and Visual Search tasks and serum levels of DHEA, DHEAS, testosterone, estrone, and cortisol were measured in the DHEA and placebo conditions. In contrast to prior experiments using the current methodology that did not demonstrate effects of DHEA administration on episodic and short-term memory tasks, the current experiment demonstrated large beneficial effects of DHEA administration on Mental Rotation, Subject-Ordered Pointing, Fragmented Picture Identification, Perceptual Identification, and Same-Different Judgment. Moreover, DHEA administration enhanced serum levels of DHEA, DHEAS, testosterone, and estrone, and regression analyses demonstrated that levels of DHEA and its metabolites were positively related to cognitive performance on the visual-spatial tasks in the DHEA condition.

A substantial portion of smokers are peri- or postmenopausal women. Cigarette smoking and menopause have overlapping negative health consequences and may act synergistically to contribute to worse health outcomes in this population. Little is known about issues specific to peri- and postmenopausal women attempting to quit smoking; however, it can be hypothesized that they face unique challenges in quitting smoking. Particularly, negative affect and vasomotor menopausal symptoms may make smoking cessation particularly challenging in this group of women. Peri- and postmenopausal women are also more prone to weight gain following smoking cessation, and concerns about postcessation weight gain may contribute to reduced motivation to quit smoking or to relapse to smoking. Recent evidence suggests that estrogen level may be positively associated with nicotine reward, which may aid in the smoking cessation efforts of postmenopausal women while possibly contributing to worse outcomes in perimenopausal women. Unfortunately, no known studies have compared premenopausal women with peri- or postmenopausal women on smoking cessation outcome variables. Studies in postmenopausal women indicate that hormone therapy (HT) use does not affect nicotine withdrawal, smoking cessation outcomes, or weight gain following smoking cessation; however, a lack of randomized trials limits the strength of these conclusions. Evidence of the effects of HT on mood following smoking cessation is conflicting. Further research is needed to identify the unique factors influencing smoking cessation in peri- and postmenopausal women and to develop and test interventions that target these variables in a way that improves cessation rates among this population.

Substance abuse treatment for pregnant women: a window of opportunity?   总被引:1,自引:0,他引:1  
Determination of the crystal structure of the human TBP-associated factor (hTAF(II))28/hTAF(II)18 heterodimer shows that these TAF(II)s form a novel histone-like pair in the TFIID complex. The histone folds in hTAF(II)28 and hTAF(II)18 were not predicted from their primary sequence, indicating that these TAF(II)s define a novel family of atypical histone fold sequences. The TAF(II)18 and TAF(II)28 histone fold motifs are also present in the N- and C-terminal regions of the SPT3 proteins, suggesting that the histone fold in SPT3 may be reconstituted by intramolecular rather than classical intermolecular interactions. The existence of additional histone-like pairs in both the TFIID and SAGA complexes shows that the histone fold is a more commonly used motif for mediating TAF-TAF interactions than previously believed.  相似文献

This article describes a brief, 12-week dialectical behavior therapy program modified for female victims of domestic abuse and provides a preliminary examination of this intervention. Dialectical behavior therapy is a comprehensive cognitive–behavioral treatment, which was originally developed to treat multiproblem clients with severe and chronic emotion dysregulation, and was adapted for this study to treat female victims of domestic abuse. From pretreatment to posttreatment, participants (N = 31) showed significant reductions in depressive symptoms, hopelessness, and general psychiatric distress as well as increased social adjustment. Additionally, participants reported high levels of consumer satisfaction with the treatment. Findings support the possible utility of dialectical behavior therapy for enhancing psychological and social well-being in female victims of domestic abuse.

Although alcohol use disorders (AUDs) adversely affect women, research on efficacious treatments for women is limited. In this randomized efficacy trial of 102 heterosexual women with AUDs, the authors compared alcohol behavioral couple therapy (ABCT) and alcohol behavioral individual therapy (ABIT) on percentage of days abstinent (PDA) and percentage of days of heavy drinking (PDH) over 6 months of treatment and 12 months of posttreatment follow-up. Baseline relationship functioning and comorbid disorders were tested as moderators of outcome. Piecewise linear growth models were used to model outcomes. During treatment, women increased their PDA and decreased their PDH, with significantly greater improvements in ABCT than in ABIT (d = 0.59 for PDA; d = 0.79 for PDH). Differences favoring ABCT were maintained during follow-up. Women with poorer baseline relationship functioning improved more on PDA during treatment with ABCT than with ABIT. For PDH, results during treatment and follow-up favored ABCT for women with better baseline relationship functioning. ABCT resulted in better outcomes than ABIT for women with Axis I disorders at the end of follow-up (PDA), and for women with Axis II disorders at the end of treatment (PDA) and at the end of follow-up (PDH).

Magnetic resonance imaging was used to measure the hippocampal and amygdalar volumes of 60 chimpanzees (Pan troglodytes). An asymmetry quotient (AQ) was then used to calculate the asymmetry for each of the structures. A one-sample t test indicated that there was a population-level right hemisphere asymmetry for the hippocampus. There was no significant population-level asymmetry for the amygdala. An analysis of variance using sex and rearing history as between-group variables showed no significant main effects or interaction effects on the AQ scores; however, males were more strongly lateralized than females. Several of these findings are consistent with results found in the human literature. (PsycINFO Database Record (c) 2010 APA, all rights reserved)  相似文献

Objective: The purpose of this study was to extend our earlier work to determine the extent to which cardiorespiratory fitness is associated with the frequency of memory problems via its effects on the hippocampus and spatial working memory. We hypothesized that age, sex, education, body composition, and physical activity were direct determinants of fitness, which, in turn, influenced frequency of forgetting indirectly through hippocampal volume and spatial working memory. Method: We conducted assessments of demographic characteristics, Body Mass Index (BMI), physical activity, cardiorespiratory fitness, hippocampal volume, spatial working memory, and frequency of forgetting in 158 older adults (M age = 66.49). Path analyses within a covariance modeling framework were used to examine relationships among these constructs. Results: Sex, age, BMI, and education were all significant determinants of cardiorespiratory fitness. The hypothesized path models for testing the effects of fitness on frequency of forgetting through hippocampal volume and accuracy and speed of spatial working memory all fit the data well. Conclusions: Our findings suggest that older adults with higher levels of fitness show greater preservation of hippocampal volume, which, in turn, is associated with more accurate and faster spatial memory and fewer episodes of forgetting. Given the proportion of older adults reporting memory problems, it is necessary to determine whether improvements in fitness brought about by physical activity interventions can result in subsequent attenuation of memory problems or potentially in improvements in memory.

In this study, the authors examined whether cognitive therapy alters the association between negative cognition and symptoms of depression. Participants were recruited during psychiatric hospitalization for depression. Following discharge, they were randomly assigned to 6 months of outpatient treatment. Treatment consisted of pharmacotherapy either alone or in combination with cognitive therapy and/or family therapy. Following this 6-month treatment period, negative cognition and symptoms of depression were assessed monthly for 1 year. Hierarchical linear modeling indicated that the association between negative cognition and depression during follow-up was weaker for patients randomized to cognitive therapy than for patients who did not receive cognitive therapy. Cognitive therapy appeared to unlink negative cognition and symptoms of depression to a greater extent than other forms of treatment.

Age at menopause has been found to be associated positively with bone mineral density, and age at menarche has been found to be associated negatively with bone mineral density. However, there have been few studies on the relations of timing of menopause and length of the reproductive period with bone mineral density. The purpose of this study was to examine the relations of timing of menopause and reproductive years (calculated as age at menopause minus age at menarche) with mineral density of the second metacarpal bone in postmenopausal Japanese women. The study population consisted of 1,035 naturally menopausal women aged 40-70 years who were screened in 1996-1997. Using computed x-ray densitometry, the authors measured bone mineral density by analyzing radiographic films of the right second metacarpal bone. Using the women with early menopause (age < 49 years) as the reference group and adjusting for age, subjects with late menopause were at decreased risk for low bone mineral density (odds ratio (OR) = 0.69, 95% confidence interval (CI) 0.49-0.97). After adjustment for additional covariates (grip strength, physical activity, body mass index, smoking, and calcium intake), the association was unchanged (OR = 0.70, 95% CI 0.50-0.99). Postmenopausal women with more reproductive years (> or = 40 years) were at decreased risk for low bone mineral density compared with those with fewer reproductive years, after adjustment for age (OR = 0.73, 95% CI 0.40-1.30) and potentially confounding factors (OR = 0.76, 95% CI 0.41-1.37); the p-value for trend was not statistically significant. In multiple linear regression analysis, early menopause and fewer reproductive years were independent predictors of low bone mineral density. In this study, postmenopausal Japanese women who had a late menopause and more reproductive years were at decreased risk for low bone mineral density, and may therefore be less prone to osteoporosis.  相似文献

Previous randomized controlled trials have not supported moderate intensity exercise as an efficacious adjunct to smoking cessation treatments for women; however, compliance with exercise programs in these studies has been poor. The purpose of this pilot study was to estimate the effects of moderate intensity exercise on smoking cessation outcomes under optimal conditions for exercise program compliance. Sixty previously sedentary, healthy, female smokers were randomized to an 8-week program consisting of brief baseline smoking cessation counseling and the nicotine patch plus either 150 min/week of moderate intensity exercise or contact control. Participants attended a median of 86.4% and 95.5% of prescribed exercise/control sessions, respectively. There was a moderate, though statistically nonsignificant, effect of exercise at post-treatment for objectively verified 7-day point prevalence abstinence (48.3% vs. 23.3%; OR = 3.07, 95% CI: 0.89–11.07) and prolonged abstinence (34.5% vs. 20.0%; OR = 2.11, 95% CI: 0.56–8.32). Effects were attenuated when controlling for potential confounders, and after a 1-month, no-treatment period. The findings provide a preliminary indication that, given adequate compliance, moderate intensity exercise may enhance short-term smoking cessation outcomes for women; however, a larger trial is warranted.

Reviews the book, Women therapists working with women: New theory and process of feminist therapy edited by Clair M. Brody (1984). As with other edited volumes on this topic, this book attempts to address a very broad range of issues confronted by a therapist holding a feminist theoretical perspective in her work. Where this is most original and successful is in the examination of the issues faced by the therapist as a woman and feminist in the social and emotional environment of therapy. This volume does not stand alone as a text on feminist therapy, and that was clearly not the editor's intention. It will probably be of most interest and use to therapists already familiar with other literature on feminist therapy, and serves to complement what has come before. I would not suggest it as any reader's first introduction to feminist therapy theory and practice. However, it is sufficiently introductory that it can be of use to any experienced psychotherapist seeking to enhance her or his consciousness of women's issues and sexism as they impact upon the process of psychotherapy.

Relapse is the rule rather than the exception among smokers attempting to quit, and compared to men, women may have higher relapse rates. The current study was a randomized clinical trial testing a palmtop computer-delivered treatment (CDT) for smoking relapse prevention among women. The intervention was individualized based on key theoretical constructs that were measured using ecological momentary assessment (EMA). All participants (N = 302) received standard smoking cessation treatment consisting of nicotine replacement therapy and group counseling, and completed EMA procedures for one week after quitting. At the completion of the group counseling sessions and EMA procedures, participants were randomized to either CDT or no further computer-delivered treatment or assessment (EMA-Only). CDT participants received a palmtop computer-delivered relapse prevention treatment for one additional month. CDT did not improve abstinence rates relative to EMA-Only. Process analyses suggested that heavier smokers were more likely to use CDT and that greater use among CDT participants may be associated with more positive outcomes. The rapid pace of technological advances in mobile computer technology and the ubiquity of such devices provide a novel platform for developing new and potentially innovative treatments. However, the current study did not demonstrate the efficacy of such technology in improving treatment outcomes. (PsycINFO Database Record (c) 2011 APA, all rights reserved)  相似文献

This study investigated the efficacy of a multimodal cognitive-behavioral intervention for women who had been treated for nonmetastatic breast cancer. Ten participants were enrolled in the treatment protocol in a multiple-baseline design. Intervention time series analyses of daily sleep diary data revealed significant improvements of sleep efficiency and total wake time. These results were corroborated by polysomnographic data. In addition, insomnia treatment was associated with significant improvements of mood, general and physical fatigue, and global and cognitive dimensions of quality of life. These findings suggest that cognitive-behavioral therapy, previously found effective for primary insomnia, is also of clinical benefit for insomnia secondary to cancer.

Afeminist approach to the psychology of women is defined. In terms of this definition four areas central to the psychology of women are examined. These areas are theory building, sex differences research, research describing women's lives, and feminist therapy. For each area past accomplishments are outlined and future directions are suggested. In conclusion, two important methodological paradoxes are presented, and their relevance to a developing feminist psychology of women is discussed.

The focus of this review is hormone replacement therapy (HRT) with continuous oral 17 beta-estradiol (herein referred to as estradiol) 2 mg/day plus sequential oral dydrogesterone 10 or 20 mg/day for 14 days of each 28-day cycle. According to data from nonblind trials, this regimen relieves climacteric symptoms, preserves bone mineral density (BMD) and improves the cardiovascular risk profile in postmenopausal women. Increases in mean BMD in the lumbar spine of 2.4 to 6.4% have been reported after 2 years' treatment. The effect on BMD of oral estradiol plus sequential dydrogesterone was similar to that achieved with transdermal estradiol plus sequential oral dydrogesterone or with oral tibolone. Good protection against endometrial hyperplasia and cancer is provided by the dydrogesterone component. Cyclical vaginal bleeding occurs in most treatment cycles, but is generally light to moderate and the time of onset is highly predictable. Noncyclical bleeding occurs in < 10% of cycles. Mean serum high density lipoprotein-cholesterol levels are increased and low density lipoprotein-cholesterol levels are decreased during treatment with oral estradiol plus sequential dydrogesterone. Insulin resistance appears to be improved. Blood pressure and bodyweight are not generally affected to any clinically important extent. Serum homocysteine levels were reported to decrease in postmenopausal women with high pretreatment levels. No data are available on the general tolerability profile of this regimen. However, the adverse events that most commonly led to discontinuation of treatment in clinical trials were typical of those associated with HRT, including vaginal bleeding headache, bloating and breast tenderness. Although the risk of breast cancer has not been specifically assessed for this regimen, it is unlikely to carry a greater risk than that of other HRT regimens. In summary available data indicate that treatment with continuous oral estradiol plus sequential dydrogesterone is effective in relieving climacteric symptoms and preserving BMD in postmenopausal women. The dydrogesterone component provides good endometrial protection and cycle control without negating the cardiovascular benefits of estradiol. Comparisons with other standard HRT regimens and long term data (including clinical end-points) are needed. In the meantime, this regimen can be regarded as an acceptable HRT option.  相似文献

The formation of an integrated memory for a pattern of stimulation could be based on the elements of that pattern becoming directly linked to one another, or by each of the elements becoming linked to a shared separate configural representation. These 2 accounts have proven difficult to discriminate between. Here, rats received exposure to four patterns of stimulation, each consisting of an auditory stimulus, a visual context, and a time of day; and we examined whether pre-training lesions to the hippocampus influenced memory for the patterns. These lesions abolished pattern memory that required configural processes (Experiments 1A and 1B) but had no effect on pattern memory that could be supported by elemental processes (Experiment 2). This dissociation provides support for the views that elemental and configural processes ordinarily support pattern memory and that rats with lesions to the hippocampus are left reliant on elemental processes.

This study examines 1-year depressive symptom and functional outcomes of 267 predominantly lowincome, young minority women randomly assigned to antidepressant medication, group or individual cognitive- behavioral therapy (CBT), or community referral. Seventy-six percent assigned to medications received 9 or more weeks of guideline-concordant doses of medications; 36% assigned to psychotherapy received 6 or more CBT sessions. Intent-to-treat, repeated measures analyses revealed that medication (p = .001) and CBT (p = .02) were superior to community referral in lowering depressive symptoms across 1-year follow-up. At Month 12, 50.9% assigned to antidepressants, 56.9% assigned to CBT, and 37.1% assigned to community referral were no longer clinically depressed. These findings suggest that both antidepressant medications and CBT result in clinically significant decreases in depression for low-income minority women.

Objective: Describe the development and preliminary evaluation of a safety awareness program for women with disabilities. Design: Baseline and postintervention questionnaires administered to a sample of women who completed a safety awareness program. Participants: Seven women with diverse disabilities. Intervention: Eight interactive sessions designed to increase protective factors. Setting: Community site for persons with disabilities. Main Outcomes: Safety self-efficacy, safety skills, social support/isolation, and safety promoting behaviors. Results: Significant increases from baseline to postintervention were found on measures of self-efficacy and safety skills. Although not statistically significant, improvements were also found in safety promoting behavior. Conclusion: Despite the small sample, findings suggest that participation in a safety awareness program may improve protective factors.

OBJECTIVE: The principal MRI features of hippocampal sclerosis are volume loss and increased T2 weighted signal intensity. Minor and localised abnormalities may be overlooked without careful quantitation. Hippocampal T2 relaxation time (HT2) can be quantified, but previously has only been measured on a few thick coronal slices with interslice gaps. In this study HT2 was measured along the entire length of the hippocampus on contiguous slices and used, with quantitative measures of hippocampal volume (HV) and distribution of atrophy, to better define the range of hippocampal sclerosis. METHODS: Thirty patients with temporal lobe epilepsy, 10 patients with extratemporal localisation related epilepsy and extratemporal lesions, and 20 control subjects were studied using MRI T2 relaxometry and volumetry. RESULTS: In controls and patients, HT2 was higher in the anterior than the posterior hippocampus. Using HV, morphometric, and HT2 data, patients with temporal lobe epilepsy were classified as unilateral diffuse hippocampal sclerosis (n=16), unilateral focal (n=6), bilaterally affected (n=6), and normal (n=2). In patients with unilateral hippocampal sclerosis, the anterior hippocampus was always affected. In three patients with normal HV, HT2 measurements disclosed unilateral focal abnormalities that corresponded to the EEG lateralisation of epileptic activity. Patients with bilateral hippocampal involvement had an earlier onset of epilepsy than patients with unilateral hippocampal sclerosis. CONCLUSIONS: Measurement of regional abnormalities of HT2 along the length of the hippocampus provides further refinement to the MRI assessment of the hippocampi in patients with temporal lobe epilepsy and is complementary to volumetric and morphological data.  相似文献
