Burnout in Mothers and Fathers of Children Surviving Brain Tumour

The aim of this paper was to investigate the occurrence of burnout among parents of brain tumour survivors. Burnout was assessed in 24 mothers and 20 fathers of childhood brain tumour survivors, using the Shirom–Melamed Burnout Questionnaire. Parents of children with no history of chronic or serious diseases served as a reference group. Mothers’ burnout scores were significantly higher compared with reference mothers. For fathers, no relation between burnout and being a parent of a brain tumour survivor was established, despite a nonsignificant tendency in the same direction as for the mothers. In conclusion, the parenting burden after a child’s brain tumour may include chronic strain, and this may be particularly taxing for mothers. The findings encourage further studies of psychological exhaustion among parents of children with special needs.     

Factors Influencing Perceptions of Breast Cancer Genetic Counseling among Women in an Urban Health Care System

The study assessed perceptions of breast cancer genetic counseling. Focus groups were conducted with twenty women (ages < = 50 years) in a Midwestern, urban health system identified as at above average risk of developing hereditary breast cancer and referred for breast cancer genetic counseling following mammography. All participants associated the words “breast cancer” with fear. African American women who received breast cancer genetic counseling may have channeled their fear into increased vigilance related to breast health. African American women who did not receive breast cancer genetic counseling were most knowledgeable about it. In contrast, Caucasian women who did not receive it reported uncertainty about the role of genetic counseling and testing in assessing breast cancer risk, mistrust in medical professionals, and lack of trust in the accuracy of genetic tests. The results could be used to help develop interventions to improve informed decision-making regarding breast cancer genetic counseling.     

Knowledge and Expectations of Women Undergoing Cancer Genetic Risk Assessment: A Qualitative Analysis of Free-Text Questionnaire Comments

Individuals undergoing cancer genetic risk assessment have been found to have a poor understanding of the process, which may affect how well they cope with learning their risk. This paper reports free-text data from questionnaires completed by women undergoing a randomised controlled trial of a psychological intervention. Of the 268 women undergoing genetic assessment for familial breast/ovarian cancer risk who were invited to take part in the trial, 157 women returned research questionnaires. Of these, 97 women provided free-text comments upon referral to a cancer genetics clinic, 62 provided comments whilst waiting for risk information (average, moderate or high), and 36 women provided comments following notification of risk. This paper reports a thematic analysis of the free-text data. Themes reflected individuals’ poor knowledge and uncertainty about genetic risk assessment. How well individuals responded to learning their risk depended upon whether expectations had been met. Regardless of risk, individuals undergoing cancer genetic risk assessment are likely to benefit from increased information about its process and timescales, and access to increased psychological support. Free-text comments can provide valuable data about individuals’ expectations and knowledge of genetics services.     

The experience of male spouses in the context of breast cancer: a systematic review of the literature

The purpose of this systematic review is to look into how the experience of husbands of women treated for breast cancer is approached in the literature. Between July and August 2015, the databases of PubMed, SciELO and BIREME were searched for papers published in the period January 2005–July 2015; a final sample of 23 papers was defined. The studies listed several negative and positive aspects of the experience, such as financial difficulties, psychological distress, lack of coping skills among family members, social recognition of the role of caregiver, acquisition of new responsibilities and the maturing of family members.     

视觉信息分布调节信息整合策略：来自眼动的证据

以空白单元格定位为实验任务,操纵序列点阵的分布,考察视觉短时记忆与视知觉的信息整合机制。实验一发现任务正确率与点阵1的圆点数呈近似U形关系。实验二发现在拐点前后被试的眼动模式从偏向于注视圆点位置转为偏向于注视空格位置。因此,视觉信息的分布模式调节整合策略,当处于视觉短时记忆中的圆点数在其容量之内时,采用图像—知觉整合策略,反之,则采用转换—比较策略。     

纳米金材料在肿瘤诊治研究中的相关进展

目前肿瘤的早期诊断依然是需要攻克的难关,现有的抗肿瘤药物因具有较大毒性且缺乏组织特异性而存在很大的局限性.纳米金基于能够被多种基团修饰后获得对肿瘤细胞的靶向性的特点逐渐成为当前抗肿瘤研究的热点.纳米金自身具有独特的生物活性,同时具有光热效应,也可以作为载体负载药物,以上3种特点均可应用于新药物的开发,用于肿瘤诊治方面的研究.本文从这三个方面描述了近期纳米金的研究进展.

Dietary restriction inhibits spatial learning ability and hippocampal cell proliferation in rats1

Abstract: We investigated the effect of dietary restriction on spatial learning ability and hippocampal cell proliferation in adult rats using two spatial learning tasks and immunohistochemical staining with 5‐bromo‐2′‐deoxyuridine (BrdU). Sixteen rats were divided into restricted or ad lib feeding groups at 70 days of age, and were trained in the delayed‐matching‐to‐place (DMTP) task (a working memory task) from 93 days of age, and then the Morris water maze task (a reference memory task). Dietary restriction had no effect on the DMTP task with 30 s delay and on the water maze task. However, in the DMTP task with 30 min delay, restricted rats performed significantly more poorly than ad lib rats. Quantitative analysis of hippocampal cell proliferation revealed that the density of newborn cells in restricted rats was significantly lower than that in ad lib rats. These results suggest that a loss of proliferating capacity in the hippocampus may be a candidate for an anatomical and biological basis for the cognitive decline caused by dietary restriction.     

GOD, DISEASE, AND SPIRITUAL DILEMMAS: READING THE LIVES OF WOMEN WITH BREAST CANCER

To write about the disease of breast cancer from both scientific and spiritual perspectives is to reflect upon our genetic and spiritual ancestry. We examine the issues involved in breast cancer at the intersections of spirituality, technology, and science, using the fundamental thing we know about being human: our bodies. Our goal in this essay is to offer close readings of women's spiritual and bodily journeys through the disease of breast cancer. We have discovered that both illness and health come within the stories of particular people and particular disciplines. And to learn more about breast cancer, both scientific and spiritual aspects, one must be attentive to such particularities. Medicine and religion are bodily experiences, and being a body-self is what it means to be human.
