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.     

Electrical stimulation versus extracorporeal magnetic innervation for urinary incontinence after radical prostatectomy

Nurses use several conservative methods for treating urinary incontinence after radical prostatectomy. Functional electrical stimulation (FES) has a recognized role, while extracorporeal magnetic innervation (ExMI) is still under evaluation in the international guidelines. Few data are available in literature, regarding comparisons between these two treatments. The aim of the study is to compare electrical stimulation and magnetic innervation for treating urinary incontinence after radical prostatectomy. Twenty‐two patients treated with ExMI and 18 treated with FES were enrolled in a retrospective study. ExMI was available for 6 weeks; the number of times ExMI was required by the patients to reduce their leakages to 10 g/d or less was compared. The groups had comparable age and body mass index. Initial leakages showed clinically relevant differences (median = 80 g/d in the ExMI patients and 150 g/d in the FES group). After 6 weeks, 71·9% of ExMI patients and 29·2% of FES patients had completed rehabilitation. The difference was statistically significant even after adjusting the analyses for initial leakages (p = 0·008). Six patients treated with ExMI had already undergone FES, with no clinically relevant results after five sessions (leakages reduction <50 g/d). The difference remained even after removing the data of these patients from the analysis (p = 0·004). Both FES and ExMI produce muscle strengthening, which is just one step of rehabilitation. Our findings suggest the possibility of using ExMI instead of FES to reduce the times required to improve muscular performance. Pelvic muscle exercises remain essential to develop the ability to automatically perform the contractions needed to avoid leakages.

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

Molybdenum(0) tricarbonyl and tetracarbonyl complexes with a cationic pyrazolylpyridine ligand: synthesis,crystal structures and catalytic performance in olefin epoxidation

The synthesis of molybdenum(0) tricarbonyl and tetracarbonyl complexes of the form [Mo(CO)₃(ptapzpy)Br] (1) and cis-[Mo(CO)₄(ptapzpy)]Br (2) is reported, where ptapzpy = 2-(1-propyltrimethylammonium-3-pyrazolyl)pyridine. Preparation of these derivatives was accomplished either through thermal replacement of CO in Mo(CO)₆ (for 1) or substitution under milder conditions of piperidine ligands in the precursor cis-[Mo(CO)₄(pip)₂] (for 2). The crystal structures of the ligand [ptapzpy]Br and complexes 1 and 2 were determined. Thermal treatment of 2 at 125–150 °C leads to mono decarbonylation and formation of 1. On the other hand, oxidative decarbonylation of 1 and 2 by reaction with tert-butylhydroperoxide (TBHP, 10 equiv.) gives a molybdenum oxide hybrid material formulated as [Mo₃O₉([ptapzpy]Br)₂]·nH₂O (3), which was characterised by FT-IR and Raman spectroscopy, thermogravimetric analysis, and ¹³C{¹H} CP MAS NMR spectroscopy. Compounds 1–3 were effective (pre)catalysts for the epoxidation of cis-cyclooctene at 55 °C with aqueous H₂O₂ or TBHP (slightly better results were obtained with the former). The characterisation of the Mo-containing solids isolated after the catalytic reaction showed that poorly soluble β-octamolybdate salts, (L)_x[Mo₈O₂₆], were formed from 1–3 with TBHP and from 1 with H₂O₂, while soluble oxoperoxo species were formed from 3 with H₂O₂. These findings helped to explain the different catalytic performances obtained.

The oxidative decarbonylation and catalytic chemistry of molybdenum(0) tricarbonyl and tetracarbonyl complexes containing the same diimine ligand are compared.
