Mental health and well-being in resident mine workers : out of the fly-in fly-out box

Objective: To explore psychosocial issues perceived to impact the mental health and well-being of resident (non-fly-in fly-out) mine workers at a local mine in regional Queensland. Design: A descriptive qualitative study using semistructured interviews. Setting: The research was conducted on-site at an opencut coal mine in regional Queensland. Participants: Ten miners (nine men) currently employed in workshop, production or supervisory roles. Main outcome measures: Self-reported issues affecting psychological well-being. Results: Participants’ occupation and the surrounding context appeared to have both positive and negative influences on their well-being. Overall findings could be grouped into four key themes: (i) the importance of relationships; (ii) the impact of lifestyle; (iii) work characteristics; and (iv) mental health attitudes. While not without strains on mental health, in general, participants reported that their current situation was superior to their previous mining jobs. This was attributed to close relationships among locally recruited workers, respect for management practices and rosters that allowed adequate sleep recovery and family time between shifts. Conclusions: This study is the first to examine mental health and well being in non-fly-in fly-out mining populations. It suggests that while some issues appear inherent in the mining occupation, personal and organisational support can help workers have a more positive workplace experience. Further work looking at more extensive comparisons over various mining contexts will greatly assist in the development of programs and support structures for rural and regional mine workers.

Using critical incident interviews to identify the mental health knowledge, skills and attitudes of entry-level dietitians

Aim: This paper aims to explore new graduates experience working with clients with mental health issues using critical incident interviews. Methods: The qualitative research techniques were based on phenomenology. A purposive sample of 19 new graduate dietitians was drawn from a range of work settings and locations throughout Australia. Data was gathered using thirty minute Critical Incident Interviews. Audio-taped data was transcribed, coded to identify common themes, compared for congruence and then categorised into knowledge, skills and attitudes. Results: New graduates encountered a range of situations involving a variety of mental health, wellbeing, dietetic and clinical issues. Common themes highlighted the mental health knowledge, skills and attitudes required for entry-level dietitians which then informed the review of the National Competency Standards for Entry-Level Dietitians. Conclusion: New graduates encounter a variety of mental health and wellbeing issues in their everyday practice and therefore require training to address these situations competently.

Is mental health education really needed?

Dietitians play a key role in supporting and advocating for the physical health care of mental health (MH) consumers, with 68-80% seeing clients with associated depression issues in Australia. The DAA Mental Health Curricula Project found dietetic training in MH was inadequate and recommended increased MH education. A MH resource package was developed and sent to universities in 2010 for incorporation into teaching. The aim of this study was to assess dietetic students’ baseline MH knowledge, attitudes and exposure prior to dietetics coursework and package implementation. An online survey measured dietetic students’ mental health knowledge (MHK), attitudes towards mental illness (MHA) and previous exposure to mental illness. MHK was assessed by sixteen dietetics-specific questions. MHA were measured by Day’s Mental Illness Stigma Scale. Exposure was assessed using an adapted version of Eack’s Social Work Students’ Experiences with Schizophrenia questions. Fifty-nine dietetic students (30% response rate) from two universities were surveyed at the beginning of dietetic coursework. Survey responses revealed students had low MHK (mean 5.48, scale 0-16) with no significant difference between cohorts (p=0.67). Half of respondents (n=31) recorded never or rarely being in contact with people with mental illness. 82% of respondents (n=48) reported having no or little experience with mental illness. Data suggests low levels of sitgmatising attitudes about people with mental illness. Given the high prevalence of clients with MH issues in everyday dietetic practice, this study is a first step in addressing integration of MH education into dietetics training.

Creative writing in recovery from severe mental illness

There is evidence that creative writing forms an important part of the recovery experience of people affected by severe mental illness. In this paper, we consider theoretical models that explain how creative writing might contribute to recovery, and we discuss the potential for creative writing in psychosocial rehabilitation. We argue that the rehabilitation benefits of creative writing might be optimized through focus on process and technique in writing, rather than content, and that consequently, the involvement of professional writers might be important. We describe a pilot workshop that deployed these principles and was well-received by participants. Finally, we make recommendations regarding the role of creative writing in psychosocial rehabilitation for people recovering from severe mental illness and suggest that the development of an evidence base regarding the effectiveness of creative writing is a priority.

Nurses’ role in caring for people with a comorbidity of mental illness and intellectual disability : A literature review

This article examines literature on the role of the nurse caring for people with a dual disability (DD) of intellectual disability and mental illness. A search of the literature between 2000 and 2010 resulted in a total of 21 articles that met the inclusion criteria. Seven key categories of the role of the nurse were identified: (i) advocacy/health promotion (including working with family); (ii) assessment/case management; (iii) behavioural interventions; (iv) communication; (v) leadership and the nurse’s role within the multidisciplinary team; (vi) functions regarding medication administration; and (vii) safety/risk management. There is a paucity of research about the role of nurses working with people with DD, although a number of opinion-based articles exist. This article identifies a need for the role of the nurse working in DD to be more clearly articulated and for the development of evidence to guide best practice.

How an urban Aboriginal and Torres Strait Islander primary health care service improved access to mental health care

Aboriginal and Torres Strait Islander people experience higher levels of psychological distress and mental ill health than their non-Indigenous counterparts, but underuse mental health services. Interventions are required to address the structural and functional access barriers that cause this underuse. In 2012, the Southern Queensland Centre of Excellence in Aboriginal and Torres Strait Islander Primary Health Care employed a psychologist and a social worker to integrate mental health care into its primary health care services. This research study examines the impact of this innovation.

Spirituality in Indian University students and its associations with socioeconomic status, religious background, social support, and mental health

The present study aimed to understand spirituality and its relationships with socioeconomic status (SES), religious background, social support, and mental health among Indian university students. It was hypothesized that: - (1) female university students will be more spiritual than male university students, - (2) four domains of spirituality will differ significantly across socioeconomic and religious background of the university students in addition to social support, and; - (3) there will be a positive relationship between spirituality and mental health of university students, irrespective of gender. A group of 475 postgraduate students aged 20–27 years, 241 males and 234 females, from various disciplines of Pondicherry University, India, participated in the study. Students’ background was collected using a structured questionnaire. Overall spirituality and its four dimensions were measured using the Spirituality Attitude Inventory, while mental health status was estimated based on scores of the psychological subscale of the WHO Quality of Life Questionnaire. Female students were significantly more spiritual than male students, particularly in spiritual practice and sense of purpose/connection. Hindu religion and lower family income were associated with lower spirituality. Higher spirituality was associated with congenial family environment and more support from teachers and classmates. There was a strong association between overall spirituality and two spirituality domains (spiritual belief and sense of purpose/connection) with better mental health. Findings suggest an opportunity for open dialogue on spirituality for university students as part of their mental health and support services that fosters a positive mind set and enhancement of resilience.

Differentiation of neural stem cells in fragile X syndrome

Multipotent stem cells can self-renew and give rise to multiple cell types. One type of mammalian multipotent stem cells are neural stem cells (NSC)s, which can generate neurons, astrocytes and oligodendrocytes. NSCs are likely involved in learning and memory, but their exact role in cognitive function in the developing and adult brain is unclear. We have studied properties of NSCs in fragile X syndrome (FXS), which is the most common form of inherited mental retardation. FXS is caused by the lack of functional fragile X mental retardation protein (FMRP). FMRP is involved in the regulation of postsynaptic protein synthesis in a group I metabotropic glutamate receptor 5 (mGluR5)-dependent manner. In the absence of functional FMRP, the formation of functional synapses is impaired in the forebrain which results in alterations in synaptic plasticity. In our studies, we found that FMRP-deficient NSCs generated more neurons and less glia than control NSCs. The newborn neurons derived from FMRP-deficient NSCs showed an abnormally immature morphology. Furthermore, FMRP-deficient NSCs exhibited aberrant oscillatory Ca2+ responses to glutamate, which were specifically abolished by an antagonist of the mGluR5 receptor. The data suggested alterations in glutamatergic differentiation of FMRP-deficient NSCs and were further supported by an accumulation of cells committed to glutamatergic lineage in the subventricular zone of the embryonic Fmr1-knockout (Fmr1-KO) neocortex. Postnatally, the aberrant cells likely contributed to abnormal formation of the neocortex. The findings suggested a defect in the differentiation of distinct glutamatergic mGluR5 responsive cells in the absence of functional FMRP. Furthermore, we found that in the early postnatal Fmr1-KO mouse brain, the expression of mRNA for regulator of G-protein signalling-4 (RGS4) was decreased which was in line with disturbed G-protein signalling in NSCs lacking FMRP. Brain derived neurotrophic factor (BDNF) promotes neuronal differentiation of NSCs as the absence of FMRP was shown to do. This led us to study the effect of impaired BDNF/TrkB receptor signaling on NSCs by overexpression of TrkB.T1 receptor isoform. We showed that changes in the relative expression levels of the full-length and truncated TrkB isoforms influenced the replication capacity of NSCs. After the differentiation, the overexpression of TrkB.T1 increased neuronal turnover. To summarize, FMRP and TrkB signaling are involved in normal differentiation of NSCs in the developing brain. Since NSCs might have potential for therapeutic interventions in a variety of neurological disorders, our findings may be useful in the design of pharmacological interventions in neurological disorders of learning and memory.

Morfometria da cabeça espermática em touros Nelore submetidos a deficiência de zinco na dieta.

Touros jovens da raça Nelore (n=6) foram mantidos em pasto formado de Brachiaria brizantha desde a desmama em dietas com diferentes níveis de zinco. Foram formados aleatoriamente dois grupos que receberam diariamente, durante dois anos, diferentes concentrações de zinco no sal mineral: T1 (n=4), os animais não receberam suplemento com zinco e T2 (n=2), 60 mg/kg/dia de Zn inorgânico suplementar. A concentração de Zn na pastagem variou de 17,8 (águas) a 12,8 mg/kg (seca), respectivamente. A partir dos 14 meses de idade, os animais foram submetidos quinzenalmente a exame de sêmen e colheita de sangue. A morfologia espermática foi estimada, incluindo a mensuração da cabeça espermática a partir de esfregaços coradas pelo método de Fuelgen, em imagens captadas digitalmente e processadas pelo software Kontron Eletronik Imaging System, KS 400-2.0. A concentração de zinco no plasma foi dosada por spectrofotometria de absorção atômica. Os resultados mostraram que os touros do T1 tiveram qualidade seminal inferior (P<0,05) em relação ao T2. Observou-se variação das características seminais em função da data da colheita, evidenciando efeito estacional sobre a qualidade do sêmen. Os defeitos mais encontrados foram de peça intermediária e cauda. A concentração de Zinco (Zn) na circulação sangüínea foi maior (P<0,01) no T1 em comparação ao T2 (0,72 ±0,01 x 0,66 ±0,01, respectivamente). A área da cabeça espermática de espermatozóides morfologicamente normais e com defeitos de cabeça, peça intermediária e cauda foi maior (P<0,01) para os touros do T1 em relação aos do T2. Ademais, espermatozóides com fragmentação nuclear apresentaram forma mais alongada quando comparados àqueles sem alterações morfológicas. As correlações encontradas sugerem a importância do Zn na qualidade seminal, especialmente pelos efeitos deletérios que sua deficiência (subclínica) causa na morfologia espermática.
