The reporting of child sexual abuse (CSA) and physician-patient sexual relationships (PPSR) are currently the focus of professional, legal and media attention in several countries. This paper briefly reviews mental health policies on these issues and reports on a WPA survey of them. While the WPA Madrid Declaration permits breaching confidentiality for mandatory reporting of CSA and clearly prohibits PPSR, it is not known how or to what extent these policies are implemented in WPA Member Societies’ countries. It is also not known whether policies or laws exist on these topics nationally or to what extent psychiatrists and the public are aware of them. Representatives of WPA Member Societies were e-mailed a survey about issues pertaining to CSA and PPSR. Fifty-one percent of 109 countries replied. All reporting countries had laws or policies regarding the reporting of CSA, but this was often voluntary (63%) and without protection for reporting psychiatrists either by law (29%) or by Member Societies (27%). A substantial number of psychiatric leaders did not know the law (27%) or their Society’s policy (11%) on these matters. With respect to PPSR, some reporting countries lacked laws or policies about PPSR with current (17%) or past (56%) patients. Fewer than half of responding representatives believed that their Society’s members or the public were well informed about the laws and policies pertaining to CSA or PPSR. There is clearly a wide range of laws, policies and practices about CSA and PPSR in WPA Member Societies’ countries. There is a need in some countries for laws or supplemental policies to facilitate the protection of vulnerable child and adult patients through clear, mandatory reporting policies for CSA and PPSR. Mechanisms to protect and support reporting psychiatrists should also be developed where they do not already exist. There is also a need in some countries to develop strategies to improve the education of psychiatrists, trainees, and the public on these issues.The Asia-Pacific region has close to half of the estimated 450 million people affected by mental illness globally 1.Based on international mental health care benchmarks, many Western health systems have established contemporary health policy and guidelines which include the provision of mental health care in the community. However, the delivery of quality and appropriate community mental health care remains an ongoing challenge for countries of both high and low socio-economic level. Difficulties and obstacles in implementation of comprehensive community service models include inadequate funding, availability of trained mental health workforce, integration with primary care services and community agencies, and collaboration between public and private health systems 2 - 3. As community mental health service system depends on sufficient workforce for service delivery, the critical shortage of adequately trained mental health staff continues to impede the progress of mental health reform.In response to such global trends, many countries in the Asia-Pacific region have begun to establish mental health policy and guidelines to move from institutional care to community mental health services. While these reforms are supported by recommendations from the World Health Organization (WHO) governing bodies, such as the Western Pacific Regional Mental Health Strategy 4, social, economic and cultural factors in Asia-Pacific countries often do not allow ready translation of Western community mental health models of care. Governments and service providers commonly face challenges in the development and implementation of locally appropriate community mental health care and services. Additionally, it would be unrealistic or undesirable to produce rigid recommendations for a singular community mental health care model, due to the diversity across the Asia-Pacific region. Hence, for constructive change to occur in the region, innovative, culturally appropriate and economically sustainable pathways for community treatment models need to be explored, developed and shared. Community mental health service reform appears to be gaining momentum in this region, despite the obstacles. Valuable lessons and inspiration for further development can be gained from both the successes and difficulties in reforming mental health systems and practices in the region.An emerging network of representatives from governments, peak bodies and key organizations is emerging in the Asia-Pacific region to build supportive relationships in order to facilitate the implementation of locally appropriate policy frameworks for community mental health service reform. The network is supported by the Asia-Pacific Community Mental Health Development (APCMHD) project, which involves 14 countries/regions in the Asia-Pacific region. Initiated in collaboration with the WHO Western Pacific Regional Office, the APCMHD project is led by Asia-Australia Mental Health, a consortium of the University of Melbourne Department of Psychiatry and Asialink, and St. Vincent’s Health, which is a part of the WHO Collaborating Centre for Mental Health (Melbourne). The project, which brought many key mental health organizations to work collaboratively, is consistent with the WHO Global Action Programme for Mental Health 5.The project aims are to promote best practice in community mental health care through exchange of knowledge and practical experience in the Asia-Pacific region. The key outcome is the documentation of the current status, strengths and needs of community mental health services in the region, in the hope to translate current understanding into practical changes in the future.  相似文献

34Fusarium graminearum Schw isolates produced 4-deoxynivalenol to form significant amounts of 4, 7 — dideoxynivalenol and lesser amounts of 4 — deoxynivalenol monoacetates on grain substratesin vitro. This is the first report on the capability a large group of naturally occurring isolates to produce 4,7-dideoxynivalenol. The average levels of 4,7-dideoxynivalenol on rice, corn, barley, and wheat as a substrate were respectively 26.8, 14.0, 12.8, and 10.5% of the level of 4-deoxynivalenol. 4, 7 — dideoxynivalenol was present in all examined naturally contaminated wheat kernel samples at levels of 1.7 to 7.9% of the level of 4-deoxynivalenol. These findings suggest that more attention should be given to the occurrence of 4,7-dideoxynivalenol in cereals.  相似文献

Proinflammatory cytokines TNF, IFNG, and IL17 play an important role in eruption of psoriasis. The activation of epidermal keratinocytes with the named cytokines alters their terminal differentiation program and causes their hyperproliferation in the diseased skin. HaCaT cells, which are immortalized human keratinocytes, are often used as a cellular model of psoriasis. The aim of this study was to evaluate changes in gene expression and the proliferation rates in cultured HaCaT cells treated with TNF, IFNG, and IL17. We found that HaCaT cells decrease their proliferation rate in response to either IL17 or a combination TNF and IFNG. The analysis of microarray data discovered a group of 12 genes, which were downregulated in HaCaT after treatments with the named cytokines and upregulated in psoriatic lesional skin. Eight genes were important for DNA replication and they also contributed to two larger networks that regulated cell progression through the cell cycle. We conclude that HaCaT cells have a sufficient limitation as a cellular model of psoriasis due to their treatment with proinflammatory cytokines, namely TNF, IFNG, and IL17 does not increase their proliferation rate. Thus, the studies of psoriasis based on HaCaT cells as an experimental model shall take in account this important phenomenon.  相似文献

The effect of lincocin (a plastid protein synthesis inhibitor) treatment on the greening process of bean (Phaseolus vulgaris L.) leaves have been studied. In comparison with control leaves treated ones had a decreased rate of chloroplast development. They had a marked chlorophyll deficiency and a decreased chlorophyll a/b ratio. Some long and short wavelength forms of chlorophyll a were lacking as evidenced from the absorption spectra at 25°C and the fluorescence spectra at 77°K. The –14CO2 fixation was inhibited by 80–90% in treated leaves. The fluorescence induced by the measuring light was greater in the treated leaves than in the control ones, and the kinetics of the decline of the relative fluorescence intensity were also different. Electron microscopic studies showed macrogranum-like structures and incomplete membrane vesicles in the treated plastids. After longer treatment a destruction of membranes was observed. The results indicate some structural and functional membrane deficiencies and instability of the membranes.  相似文献
