MENTAL HEALTH SERVICES FOR PERSONS WITH MENTAL RETARDATION: ROLE OF THE ADVANCED PRACTICE PSYCHIATRIC NURSE

The term dual diagnosis is frequently used by mental health professionals to refer to people who have mental illness complicated by substance abuse. A less commonly recognized population are those individuals who have the dual diagnosis of mental retardation and mental illness. In this paper the author discusses (1) the mental health needs of persons with mental retardation and (2) the current state of services for them. There is a significant lack of appropriately trained professionals to help address the needs of this population. Traditionally, nurses have primarily been identified as providers of physical care. Advanced practice psychiatric nurses, however, are an underutilized group of professionals who have the capacity to assume a leadership role in clinical care, service coordination, and advocacy for individuals and families affected by mental illness and mental retardation.     

Probiotic and enterohemorrhagic Escherichia coli: An effective strategy against a deadly enemy?

Enterohemorrhagic Escherichia coli (EHEC) are major food-borne pathogens that constitute a serious public health threat. Currently, there is no specific treatment available for EHEC infections in human creating an urgent need for the development of alternative therapeutic strategies. Among them, one of the most promising approaches is the use of probiotic microorganisms. Even if many studies have shown the antagonistic effects of probiotic bacteria or yeast on EHEC survival, virulence, adhesion on intestinal epithelium or pathogen-induced inflammatory responses, mechanisms mediating their beneficial effects remain unclear. This review describes EHEC pathogenesis and novel therapeutic strategies, with a particular emphasis on probiotics. The interests and limits of a probiotic-based approach and the way it might be incorporated into global health strategies against EHEC infections will be discussed.     

Commercial ‘ready‐to‐feed’ infant foods in the UK: macro‐nutrient content and composition

Quantitative analyses of the macronutrient content of eight popular commercial ‘ready‐to‐feed’ baby meals for 6–9‐month old infants in the UK market have been undertaken in order to ascertain their nutritional suitability in relation to the total daily dietary intake as well as nutritional profiling of the products. The chemical analyses conducted included Kjeldhal for protein, acid hydrolysis and extraction for fat, phenol sulphuric acid for carbohydrate and Association of Official Analytical Chemists 985.29 for fibre. The only difference found between different varieties (meat‐ and vegetable‐based) was with respect to the protein content (P = 0.04) per 100 g of food. The experimentally determined concentrations of macronutrients (g/100 kcal) were compared with the declared values provided by the manufacturers on the product labels and, despite some variations, the values obtained comply with regulatory requirements (Commission Directive 2006/125/EC). The total daily intake of fat (27.0 g per day) – based on the menu composed from commercial complementary food – is suggested to exceed the daily recommended values for fat (31%), if the intake of snacks and desserts are incorporated. These findings imply that the formulation of recipes, based on a standard commercial menu, is an important consideration in relation to the nutritional quality of the diet of infants.

The use of psychiatry‐focused simulation in undergraduate nursing education: A systematic search and review

Evidence on the use of simulation to teach psychiatry and mental health (including addiction) content is emerging, yet no summary of the implementation processes or associated outcomes exists. The aim of this study was to systematically search and review empirical literature on the use of psychiatry‐focused simulation in undergraduate nursing education. Objectives were to (i) assess the methodological quality of existing evidence on the use of simulation to teach mental health content to undergraduate nursing students, (ii) describe the operationalization of the simulations, and (iii) summarize the associated quantitative and qualitative outcomes. We conducted online database (MEDLINE, Embase, ERIC, CINAHL, PsycINFO from January 2004 to October 2015) and grey literature searches. Thirty‐two simulation studies were identified describing and evaluating six types of simulations (standardized patients, audio simulations, high‐fidelity simulators, virtual world, multimodal, and tabletop). Overall, 2724 participants were included in the studies. Studies reflected a limited number of intervention designs, and outcomes were evaluated with qualitative and quantitative methods incorporating a variety of tools. Results indicated that simulation was effective in reducing student anxiety and improving their knowledge, empathy, communication, and confidence. The summarized qualitative findings all supported the benefit of simulation; however, more research is needed to assess the comparative effectiveness of the types of simulations. Recommendations from the findings include the development of guidelines for educators to deliver each simulation component (briefing, active simulation, debriefing). Finally, consensus around appropriate training of facilitators is needed, as is consistent and agreed upon simulation terminology.     

Young carers in South Africa: tasks undertaken by children in households affected by HIV infection and other illness

‘Young carers’ are children who take on adult responsibility in response to familial illness. South Africa’s high disease burden, limited health care capacity and cultural notions of children’s familial duty suggest a large population of ‘young carers’ in this country. This study aims to explore the nature of responsibility among children affected by illness in deprived South African communities. A total of 349 children and adolescents aged 10–18 years in illness-affected households in the Western Cape province were recruited via community- and school-based convenience sampling. Data about their daily life, responsibilities and the impact of familial illness were collected via semi-structured interviews. Caring tasks involving intimate contact and medical treatments were relatively common among children in the sample, and nearly all children were engaged in some type of responsibility, from caring tasks to housework, childcare and earning money. Children frequently indicated their responsibilities constituted a substantial burden. Responses suggested a tension between duty to care and appropriateness of intimate contact between parents and children required for some caring responsibilities. Children often linked their tasks burden to familial illness, though further quantitative research is needed to identify the drivers of child responsibility.     

Mental health of youth orphaned due to AIDS in South Africa: biological and supportive links to caregivers

This research explored the biological and social support relationship between youth orphaned due to AIDS and his/her caregiver to identify protective factors that are related to positive mental health outcomes. These youth have significantly higher levels of depression, anxiety, and post-traumatic stress (PTS) symptoms compared to those orphaned due to other causes and non-orphans. Using a 2009 cross-sectional data-set from South Africa, 254 youth orphaned due to AIDS were purposively selected from the overall sample of 732 to further examine this caregiver relationship. Caregiver relation was analyzed in several combinations to determine if it was significantly related to mental health outcomes, with only anxiety showing significance. Those living with a biological parent had significantly higher anxiety symptoms than those living with a grandparent, other kin, or non-kin. Anxiety was also significantly related to an increased age, lower levels of emotional support, and lower levels of instrumental/financial support (R² = .153). Age was the only significant variable from the model that was related to depression symptoms (R² = .111). PTS symptoms were related to increases in age, lower levels of emotional support, instrumental/financial support, and satisfaction with the caregiver (R² = .194). Gender and age were related to suicidal tendencies, specifically boys were 2.26 times more likely to exhibit suicidal tendencies compared to girls, and every yearly increase in age results in the youth being 1.22 times more likely to exhibit suicidal tendencies. Strengthening the caregiver’s ability to provide social support for the child is critical, irrespective of any biological kin relationship.     

Acute morphine affects the rat circadian clock via rhythms of phosphorylated ERK1/2 and GSK3β kinases and Per1 expression in the rat suprachiasmatic nucleus

Background and Purpose

Opioids affect the circadian clock and may change the timing of many physiological processes. This study was undertaken to investigate the daily changes in sensitivity of the circadian pacemaker to an analgesic dose of morphine, and to uncover a possible interplay between circadian and opioid signalling.

Experimental Approach

A time-dependent effect of morphine (1 mg·kg⁻¹, i.p.) applied either during the day or during the early night was followed, and the levels of phosphorylated ERK1/2, GSK3β, c-Fos and Per genes were assessed by immunohistochemistry and in situ hybridization. The effect of morphine pretreatment on light-induced pERK and c-Fos was examined, and day/night difference in activity of opioid receptors was evaluated by [³⁵S]-GTPγS binding assay.

Key Results

Morphine stimulated a rise in pERK1/2 and pGSK3β levels in the suprachiasmatic nucleus (SCN) when applied during the day but significantly reduced both kinases when applied during the night. Morphine at night transiently induced Period1 but not Period2 in the SCN and did not attenuate the light-induced level of pERK1/2 and c-Fos in the SCN. The activity of all three principal opioid receptors was high during the day but decreased significantly at night, except for the δ receptor. Finally, we demonstrated daily profiles of pERK1/2 and pGSK3β levels in the rat ventrolateral and dorsomedial SCN.

Conclusions and Implications

Our data suggest that the phase-shifting effect of opioids may be mediated via post-translational modification of clock proteins by means of activated ERK1/2 and GSK3β.Tables of Links
