Inside the competences evaluation, the stress tolerance of students. An empirical study based on conservation of resources theory

Competence development is considered a preventive strategy of burnout. At an organizational context some competences could be linked as precursors or consequences. In self-assessment of competence development, students perceive stress tolerance as a priority competence to ameliorate. Moreover employers and recruitment consultants agree that this is a new authentic challenge for organizations. The main reasons of this result are debated, this study should consider the importance of competence development from a holistic point of view. In addition it considers the exploration of the relationship between stress tolerance and competence development, according to Conservation Resources (COR) theory (Hobfoll 1988, 1989, 1998, 2004) where the resource loss is considered the principal component in the stress process

L'Exercici de la docència de la psicologia i el Burnout

En l’actualitat el burnout o síndrome de cremar-se per la feina és considerat un risc emergent als països occidentals essent el col·lectiu docent un dels més afectats. L’espai europeu d’educació superior proposa un nou rol pel professor que haurà de ser compaginat amb la gestió, la recerca i la transferència de coneixement. En la present recerca s’analitza el nivell de burnout en una mostra formada per 42 docents (mitjana d’edat: 37,21 anys; D.T.: 8,98; 70,8% dones) del departament de Psicologia de la Universitat de Girona. El burnout s’ha avaluat amb el Maslach Burnout Inventory (MBI) així com amb un qüestionari d’elaboració pròpia que recull variables sociodemogràfiques, característiques del tipus de treball i de l’ús del temps lliure, el locus de control i el burnout percebut. Els resultats obtinguts indiquen valors mitjans en les puntuacions de les dimensions Cansament Emocional i Despersonalització, i valors elevats en Realització Personal. El 20,5% dels docents es percep cremat per la feina

The severity of malarial anaemia in Plasmodium chabaudi infections of BALB/c mice is determined independently of the number of circulating parasites

Background: Severe malarial anaemia is a major complication of malaria infection and is multifactorial resulting from loss of circulating red blood cells (RBCs) from parasite replication, as well as immune-mediated mechanisms. An understanding of the causes of severe malarial anaemia is necessary to develop and implement new therapeutic strategies to tackle this syndrome of malaria infection. Methods: Using analysis of variance, this work investigated whether parasite-destruction of RBCs always accounts for the severity of malarial anaemia during infections of the rodent malaria model Plasmodium chabaudi in mice of a BALB/c background. Differences in anaemia between two different clones of P. chabaudi were also examined. Results: Circulating parasite numbers were not correlated with the severity of anaemia in either BALB/c mice or under more severe conditions of anaemia in BALB/c RAG2 deficient mice (lacking T and B cells). Mice infected with P. chabaudi clone CB suffered more severe anaemia than mice infected with clone AS, but this was not correlated with the number of parasites in the circulation. Instead, the peak percentage of parasitized RBCs was higher in CB-infected animals than in AS-infected animals, and was correlated with the severity of anaemia, suggesting that the availability of uninfected RBCs was impaired in CB-infected animals. Conclusion: This work shows that parasite numbers are a more relevant measure of parasite levels in P. chabaudi infection than % parasitaemia, a measure that does not take anaemia into account. The lack of correlation between parasite numbers and the drop in circulating RBCs in this experimental model of malaria support a role for the host response in the impairment or destruction of uninfected RBC in P. chabaudi infections, and thus development of acute anaemia in this malaria model.

A behavioral comparison of male and female adults with high functioning autism spectrum conditions

Autism spectrum conditions (ASC) affect more males than females in the general population. However, within ASC it is unclear if there are phenotypic sex differences. Testing for similarities and differences between the sexes is important not only for clinical assessment but also has implications for theories of typical sex differences and of autism. Using cognitive and behavioral measures, we investigated similarities and differences between the sexes in age- and IQ-matched adults with ASC (high-functioning autism or Asperger syndrome). Of the 83 (45 males and 38 females) participants, 62 (33 males and 29 females) met Autism Diagnostic Interview-Revised (ADI-R) cut-off criteria for autism in childhood and were included in all subsequent analyses. The severity of childhood core autism symptoms did not differ between the sexes. Males and females also did not differ in self-reported empathy, systemizing, anxiety, depression, and obsessive-compulsive traits/symptoms or mentalizing performance. However, adult females with ASC showed more lifetime sensory symptoms (p = 0.036), fewer current socio-communication difficulties (p = 0.001), and more self-reported autistic traits (p = 0.012) than males. In addition, females with ASC who also had developmental language delay had lower current performance IQ than those without developmental language delay (p<0.001), a pattern not seen in males. The absence of typical sex differences in empathizing-systemizing profiles within the autism spectrum confirms a prediction from the extreme male brain theory. Behavioral sex differences within ASC may also reflect different developmental mechanisms between males and females with ASC. We discuss the importance of the superficially better socio-communication ability in adult females with ASC in terms of why females with ASC may more often go under-recognized, and receive their diagnosis later, than males.

The genetics of diabetes mellitus

Genes play an important role in the development of diabetes mellitus. Putative susceptibility genes could be the key to the development of diabetes. Type 1 diabetes mellitus is one of the most common chronic diseases of childhood. A combination of genetic and environmental factors is most likely the cause of Type 1 diabetes. The pathogenetic sequence leading to the selective autoimmune destruction of islet beta-cells and development of Type 1 diabetes involves genetic factors, environmental factors, immune regulation and chemical mediators. Unlike Type 1 diabetes mellitus, Type 2 diabetes is often considered a polygenic disorder with multiple genes located on different chromosomes being associated with this condition. This is further complicated by numerous environmental factors which also contribute to the clinical manifestation of the disorder in genetically predisposed persons. Only a minority of cases of type 2 diabetes are caused by single gene defects such as maturity onset diabetes of the young (MODY), syndrome of insulin resistance (insulin receptor defect) and maternally inherited diabetes and deafness (mitochondrial gene defect). Although Type 2 diabetes mellitus appears in almost epidemic proportions our knowledge of the mechanism of this disease is limited. More information about insulin secretion and action and the genetic variability of the various factors involved will contribute to better understanding and classification of this group of diseases. This article discusses the results of various genetic studies on diabetes with special reference to Indian population.

Effect of endurance training upon lipid metabolism in the liver of cachectic tumour-bearing rats

The syndrome of cancer cachexia is accompanied by several alterations in lipid metabolism, and the liver is markedly affected. Previous Studies showed that moderate exercise training may prevent liver fill accumulation through diminished delivery of lipids to the liver, increased hepatic oxidation and increased incorporation of triacylglycerol (TAG) into very low density lipoprotein (VLDL). Our aim was to examine the influence of moderate intensity training (8 weeks) upon TAG content, VLDL assembly and secretion, apolipoprotein B (apoB) and microsomal transfer protein (MTP) gene expression in the liver of cachectic tumour-bearing rats. Animals were randomly assigned to a sedentary control (SC), sedentary tumour-bearing (ST) or exercise-trained control (EC) or to all exercise trained tumour-bearing (ET) group. Trained rats ran on a treadmill (60% VO2max) for 60 min day(-1), 5 day week(-1), for 8 weeks. TAG content and the rate of VLDL secretion (followed for 3 h), its well its mRNA expression of apoB and MTP, and total cholesterol, VLDL-TAG, VLDL-cholesterol, high density lipoprotein cholesterol (HDL-cholesterol) and tumor weight were evaluated. VLDL-cholesterol showed a decrease in ST (p < 0.05) in relation to SC. Serum TAG, VLDL-TAG and tissue TAG content were all increased in ST (p < 0.01), when compared with SC. ST showed a lower rate of VLDL secretion (p < 0.05) and reduced expression of apoB (p < 0.001) and MTP (p < 0.001), when compared with SC. These parameters were restored to control values (p < 0.05) when the animals were submitted to the exercise training protocol. Tumour weight decreased 10-fold after training (p < 0.001). It is possible to affirm, therefore, that endurance training promoted the re-establishment of lipid metabolism in cachectic tumour-bearing animals, especially in relation to VLDL secretion and assembly.

Work context, personal control, and burnout amongst nurses

While situational factors such as high workloads have been found to be predictive of burnout, not all people in the same work context develop burnout. This suggests that individual factors are implicated in susceptibility to burnout. We investigated the relationships between care type (acute/chronic), neuroticism, control (primary/secondary), and symptoms of burnout (exhaustion, cynicism, and reduced professional efficacy) amongst 21 chronic care nurses and 83 acute care nurses working in a public hospital in regional Australia. Similar levels of burnout symptomatology and neuroticism were found in each group of nurses, and neuroticism was found to be associated with exhaustion, cynicism, and reduced professional efficacy in the total sample of nurses. Our prediction that primary control would protect against burnout symptoms in acute care nurses was supported only for professional efficacy, and the prediction that secondary control would protect against burnout in chronic care nurses was not supported.

The phenomenon of resilience in crisis care mental health clinicians

The purpose of this study, undertaken in 2003, was to explore the phenomenon of resilience as experienced by Australian crisis care mental health clinicians working in a highly demanding, complex, specialized and stressful environment. For the purpose of this research, the term 'resilience' was defined as the ability of an individual to bounce back from adversity and persevere through difficult times. The six participants for this study were drawn from Melbourne metropolitan mental health organizations – the disciplines of nursing, allied health and medicine. A number of themes were explicated from the participants' interview transcripts – Participants identified the experience of resilience through five exhaustive descriptions, which included: 'The team is a protective veneer to the stress of the work'; Sense of self; Faith and hope; Having insight; and Looking after yourself. These exhaustive descriptions were integrated into a fundamental structure of resilience for clinicians in this role. The study's findings have the potential to inform organizations in mental health to promote resilience in clinicians, with the potential to reduce the risk of burnout and hence staff attrition, and promote staff retention and occupational mental health.

Managing behavioural symptoms of dementia : Effectiveness of staff education and peer support

This study was designed to investigate the impact of staff education on the behaviour and quality of life of residents with dementia and on staff members' attitudes about working with people with dementia and level of burnout. Staff from three aged care facilities participated in the study (n = 52). These facilities were randomly assigned to one of two intervention groups or a control group. Staff assigned to the intervention groups received an eight-week behaviourally-based programme. Staff from one aged care facility also participated in a peer support group designed to reinforce educational material and facilitate positive changes among staff members. Behavioural symptoms displayed by residents (n = 76) in each of the facilities were also assessed. Assessments were conducted at pre-intervention, post-intervention, three- and six-month follow-up. The results of this study indicated that education or peer support was not associated with an improvement in resident behaviour or quality of life. Education or peer support also did not impact on staff members' level of burnout. There was, however, a change in staff members' attitudes about working with people with dementia. Possible explanations for these findings and implication for further research are considered.

Injury and burnout in Australian athletes

The relationship between injury and burnout in a sample of 264 local to international Australian athletes (124 men and 140 women) was studied. Injury can be a stressful experience for athletes; coupled with the demands of rehabilitation, it could increase feelings of burnout. Experiencing more than one injury could have a cumulative effect on feelings of burnout. Alternatively, for some athletes the break from training or competing caused by an injury could alleviate burnout symptoms. Participants completed a demographic questionnaire and a modified version of the Maslach Burnout Inventory. Independent sample t tests indicated that currently injured athletes (n = 150) had significantly lower mean Burnout scores than currently uninjured athletes (n = 113). Small, but statistically significant, positive correlations were found between number of injuries and Burnout scores. Possible explanations are that injury provides a temporary break from intense sporting involvement and, thus, lower scores on Burnout, but multiple injuries might have a cumulative effect on burnout.

Burnout in physicians : a case for peer-support

Background: It is well documented that doctors experience a high level of stress in their profession, and that this can lead to physical, psychological, and emotional harm, in particular, burnout. Overseas (especially in the UK and USA), research investigating the levels of stress, burnout, and associated psychiatric morbidity in health professionals, across many specialities, has been carried out with a view to prevention of these adverse outcomes.

Aims: To assess the level of burnout in a sample of New Zealand physicians, the associated work and personal characteristics, and the need for development of a support peer supervision or support system.

Methods: Questionnaires that measured a number of work and personal characteristics, including the Maslach Burnout Inventory, the General Health Questionnaire, and additional questions regarding mistakes, and need for support, were sent to 83 physicians in the Waikato and Bay of Plenty areas. Analysis involved descriptive statistics, with t-tests for comparison with other studies, Pearson Product-Moment correlations between variables and analysis of variance where appropriate.

Results: Of the 50 respondents, 28% experienced high levels of two or three aspects of burnout (emotional exhaustion, depersonalization, low personal accomplishment). Emotional exhaustion correlated with a greater need for support. Most respondents favoured a one-to-one support system.

Conclusion: This study highlights the presence of significant workplace difficulties for physicians and the need to develop a preventative support system for the protection of physicians and the patients in their care.

Prevalence of pre-frailty for the component of gait speed in older adults

OBJETIVO: investigar a pré-fragilidade e os fatores associados a essa condição, considerando as medidas de velocidade da marcha dos idosos. MÉTODO: a seleção dos participantes ocorreu por meio de critérios de inclusão/exclusão e teste de rastreamento cognitivo. A amostra foi calculada com base na estimativa da proporção populacional e constituída por 195 idosos, usuários de uma Unidade Básica de Saúde de Curitiba, PR. Os dados foram coletados mediante questionário sociodemográfico/clínico e teste de velocidade da marcha. RESULTADOS: a pré-fragilidade para velocidade da marcha possui moderada prevalência (27,3%) e associou-se à faixa etária entre 60 e 69 anos, baixa escolaridade, não se sentir solitário, utilizar anti-hipertensivo, apresentar doença cardiovascular e sobrepeso. CONCLUSÃO: considera-se relevante identificar os idosos na condição de pré-fragilidade, pois, dessa maneira, existe a possibilidade de intervenção imediata com a finalidade de estacionamento do quadro. É significativo o déficit de estudos sobre a síndrome da fragilidade em idosos brasileiros, principalmente aqueles que se referem a um componente isolado. Visto que a enfermagem gerontológica se encontra nos primeiros passos referentes à temática, entende-se que a identificação da prevalência deve ser o ponto primordial das pesquisas sobre o tema.
