Severe mental disorders in complex emergencies

People with severe mental disorders are a neglected and vulnerable group in complex emergencies. Here, we describe field experiences in establishing mental health services in five humanitarian settings. We show data to quantify the issue, and suggest reasons for this neglect. We then outline the actions needed to establish services in these settings, including the provision of practical training, medication, psychosocial supports, and, when appropriate, work with traditional healers. We have identified some persisting problems locally, nationally, and internationally, and suggest some solutions. Protection and care of people with severe mental disorders in complex emergencies is a humanitarian responsibility.     

Home visits for frail older people: a qualitative study on the needs and preferences of frail older people and their informal caregivers

Background

A number of studies have examined the effects of home visits and showed inconsistent results on physical functioning, institutionalisation, and mortality. Despite continuing interest from professionals in home visits for older people, reports on older people’s needs and preferences for such visits are scarce.

Aim

This qualitative study aims to explore the views and needs of community-dwelling frail older people concerning home visits.

Design and setting

A qualitative study including interviews with frail older persons and their informal caregivers living in the area of Nijmegen, the Netherlands.

Method

Semi-structured interviews were conducted with frail older people and informal caregivers. A grounded theory approach was used for data-analysis.

Results

Eleven frail older people and 11 informal caregivers were included. Most participants emphasised the importance of home visits for frail older people. They felt that it would give older people the personal attention they used to receive from GPs but miss nowadays. Most stated that this would give them more trust in GPs. Participants stated that trust is one of the most important factors in a good patient–professional relationship. Further, participants preferred home visits to focus on the psychosocial context of the patient. They stated that more knowledge of the psychosocial context and a good patient–professional relationship would enable the professional to provide better and more patient-centred care.

Conclusion

Patients’ expectations of home visits are quite different from the actual purpose of home visiting programmes; that is, care and wellbeing versus cure and prevention. This difference may partly explain why the effectiveness of home visits remains controversial. Future studies on home visits should involve patients in the development of home visiting programmes.     

The effect of the Fanconi anemia polypeptide, FAC, upon p53 induction and G2 checkpoint regulation

Fanconi anemia (FA) is an autosomal recessive disease marked by developmental defects, bone marrow failure, and cancer susceptibility. FA cells are hypersensitive to DNA cross-linking and alkylating agents and accumulate in the G2 phase of the cell cycle in response to these agents. FA cells also display genomic instability, suggesting a possible defect in the p53 pathway. To test the effect of heterologous expression of FAC cDNA on drug-induced cytotoxicity, G2 accumulation, and p53 induction in FA cells, we compared two isogenic FA cell lines: HSC536N (mock), a FA type C cell line sensitive to mitomycin C (MMC), and the same cell line transfected (corrected) with wild-type FAC cDNA (HSC536N [+FAC]). HSC536N (+FAC) cells showed a 30-fold increase in resistance to MMC concentration. Similarly, increases in resistance were observed following exposure to cisplatin, carboplatin, and cyclophosphamide. In addition, HSC536N (+FAC) cells showed a twofold lower G2 accumulation following MMC treatment. To analyze the possible interaction of FAC with the p53 pathway, we analyzed p53 induction in mock and corrected cell lines following exposure to MMC. HSC536N (mock) cells induced p53 at lower MMC concentrations than HSC536N (corrected). Caffeine, a known G2 checkpoint inhibitor, not only inhibited G2 accumulation seen in both cell lines but also caused the resistant HSC536N (+FAC) to become as sensitive to MMC as HSC536N (mock) cell line. We conclude that the FAC protein has a specific cytoprotective effect and may function as a cell cycle regulator of the G2 phase of the cell cycle.     

Estrogens and brain function

Cognitive decline is well recognized during ageing but is often accelerated in women after menopause. Studies have shown that there are significant gender differences in brain ageing with significantly greater changes in brain structure, function and metabolism between females and males. Estrogens exert protective effects on neuronal cells in culture but the exact underlying mechanism for their neuroprotective effect in humans is not completely understood. Estrogens have been shown to affect the nervous system in many different ways: via binding to estrogen receptors (ERs) but also via multiple pathways. The results of small randomized trials and larger observational studies suggest a beneficial effect of estrogen therapy on cognitive function in symptomatic postmenopausal women. However, the results of the Women's Health Initiative Study (WHIMS) do not support this, at least not in women over the age of 65. Alzheimer's disease (AD) is two to three times more common in women than in men. Based on currently available data, routine therapeutic use of estrogens in women with AD is not justified but it may have a role in the prophylaxis of AD. The existing evidence supports the use of HRT only in women with menopausal symptoms for a few years following menopause.
