Absence motivated by illness: A non-concurrent prospective study of physical education teachers in the municipal education system of the city of Campinas, São Paulo, Brazil

The object of this investigation was to identify and analize aspects of the health status related to absenteism in physical education teachers in the municipal education system of the city of Campinas, Brazil, as related to the medical leave program. The non-concurrent prospective study was accomplished by means of a comparison with teachers who work only in the classroom, refering to a three year period. In the variables of greatest interest, the Pearson non-parametric chi-square (X2) statistical test was adopted. Calculations of relative risk and level of confidence were made using the Epi-info computer program. Significant differences were observed in the following diagnostic groups favoring the not exposed group: i) Supplementary Classification of factors that exercise influence over the health status and access to health services and ii) Digestive system illness; while the physical education teachers showed a significant difference in: i) diseases of the musculoskeletal and connective tissue system and ii) Injuries and poisoing. Possible explications for some of the adverse effects as well as the protective ones that were observed include physical activity as a way of life along with being a physical education teacher and on the other side, peculiar behavior of epidemiological descriptive characteristics, like sex and age, within the socio-economic context of the country. © Copyright Moreira Jr. Editora.

The association between beliefs about low back pain and work presenteeism

OBJECTIVE: To examine the influence of beliefs about low back pain (LBP) on reduced productivity at work ("presenteeism") caused by LBP. METHODS: Two thousand five hundred seven individuals completed the Back Beliefs Questionnaire, the Fear Avoidance Beliefs questionnaire (FABQ), and questions about LBP-related work-absence, reduced work-productivity, pain, comorbidity, and demographics. RESULTS: Six hundred seventy (25%) individuals were of working age, employed and reported current LBP. Univariate models showed beliefs were more "negative" in individuals with work-absence and reduced productivity (P = 0.0001). In multivariable analysis, controlling for confounders, "FABQwork" was a unique predictor of both absenteeism and presenteeism (each, P = 0.0001), though with small effect sizes. CONCLUSIONS: Negative beliefs about LBP are associated with both work absence and reduced work-productivity. Further investigations should examine their potential as a target for educational interventions when considering initiatives to reduce the socioeconomic costs of LBP.

Análise do padrão de recrutamento abdominal em crianças com dor espinal, entre os 7 e os 10 anos, durante a flexão rápida do ombro, com recurso a electromiografia de superfície

Estudos epidemiológicos dão conta de um aumento exponencial de crianças que reportam dor espinal nalgum momento da vida, tendo-se vindo a atribuir a esta um interesse crescente. Nesta sequência têm vindo a ser estudados factores de risco para a dor espinal, cujo leque tem aumentado devido ao contexto social em que nos inserimos. Um dos aspectos sobre o qual recai a nossa investigação relaciona-se com a activação muscular nas crianças com dor espinal, aspecto ainda não estudado nesta população em particular. A literatura indica que, na população adulta sem dor espinal existe pré-activação muscular abdominal aquando da flexão rápida do ombro e a maioria dos estudos revistos apontam para a inexistência da mesma nos indivíduos com dor espinal. Apesar disso, não existem evidências que o demonstrem em crianças pelo que o nosso estudo pretende descrever o padrão de recrutamento abdominal utilizado pelas crianças com dor espinal, aquando do movimento rápido do membro superior bem como analisar os principais factores de risco. Para recolha dos dados utilizou-se o Questionário de Dor Adaptado, para rastrear a amostra com dor espinal e descrever a sua história ocupacional, e Electromiografia de Superfície, com utilização do acelerómetro, que nos deu conta do início do movimento. Os dados obtidos neste estudo indicam que existe activação muscular abdominal, no momento imediatamente prévio ao início do movimento de flexão do ombro, em quase toda a musculatura abdominal, em crianças com dor espinal excepto em dois participantes que revelam um atraso na activação do músculo oblíquo interno direito e num outro que revela um atraso na activação do recto abdominal. Um dos participantes apresentou pré-activação em todos os músculos estudados. Isto provavelmente encontra-se relacionado com o processo de maturação e indica que possivelmente esta é uma boa altura para prevenir a evolução da dor e possíveis futuros problemas ocupacionais daí advindos, como faltar ao trabalho e ter uma baixa participação social. Estudos futuros devem debruçar-se sobre esta temática e sobre a delineação de novos programas, desta feita de prevenção, de modo a evitar problemas ocupacionais na idade adulta, já que crianças com dor são mais susceptíveis de se tornarem adultos com dor crónica.

A Health- and Resource-Oriented Perspective on NSLBP

Nonspecific low back pain (NSLBP) is an important health issue of our time. Personal as well as economic factors, like suffering pain and experiencing disability on the one hand and enormous and still increasing costs to the economy and society on the other hand, display the importance of the matter. Tremendous research has been conducted in the last few decades on NSLBP. A PubMed search (June 17, 2013) on “low back pain” provided 22,980 hits, and when specifying for “low back pain, systematic review,” 3,134 hits were still generated. Most research has been done examining the development, risk factors, or therapeutic measures of NSLBP, but hardly any literature exists on resources related to NSLBP. The aims of this review are twofold. In order to shade light on the salutogenetic approach of NSLBP, and thus to focus on health instead of illness, the first aim is to facilitate the understanding of which therapeutic measures enhance the ability to cope with chronic NSLBP and enable (more) normal functioning in life. The second aim is to stimulate the understanding of resources protecting against the onset of NSLBP or against the development of chronic NSLBP and its resulting work absence.

Caracterización de las condiciones de salud y de trabajo y su relación con lesiones cutáneas en los orfebres artesanales de Mompox Bolivar-Colombia 2015

INTRODUCCIÓN Las alteraciones de la salud relacionadas con el trabajo (enfermedades y accidentes), pueden prevenirse desde las actividades bien enfocadas del Sistema de Gestión de Seguridad y Salud en el Trabajo (SGSST), realizando la identificación y control de los agentes causales en el ambiente de trabajo y la vigilancia de la salud de la población trabajadora. El proyecto desarrollado va dirigido a un grupo específico de artesanos orfebres en la ciudad de Mompox, Bolivar, en la que esta labor artesanal se centra en el arte de la filigrana, transmitido generacionalmente desde antaño En esta ciudad los artesanos orfebres, aunque corresponden a un sector informal de la economía, se encuentran agremiados principalmente en tres asociaciones ubicadas en la cabecera municipal. En el desempeño de sus labores, estos profesionales del arte de la filigrana manipulan agentes químicos como el ácido nítrico, el ácido sulfúrico, la plata y el mercurio, los cuales se utilizan en las diferentes etapas del proceso que incluye técnicas propias de esta labor. Teniendo en cuenta que la información disponible en la literatura científica describe principalmente los efectos de agentes químicos en otros oficios diferentes a la población orfebre y conociendo que la exposición a estas sustancias químicas puede generar variados efectos en el organismo, el interés de este proyecto se centra específicamente en las alteraciones cutáneas posiblemente relacionadas con las condiciones de trabajo de esta población del sector informal. MATERIALES Y METODOS La presente investigación es un estudio de corte trasversal, el cual realizó una selección por conveniencia de 114 trabajadores de orfebres Momposinos con el fin de identificar la relación de las condiciones de trabajo con la presencia de alteraciones cutáneas de los trabajadores que laboran en la orfebrería artesanal en la ciudad de Mompox, departamento de Bolívar, en el año 2015, de tal manera que dejando a consideración la descripción de los hallazgos encontrados, se posibiliten futuras y precisas investigaciones e intervenciones en este colectivo de trabajadores. Los instrumentos empleados para la recolección de la información y para el cumplimento de los objetivos fueron la encuesta Nacional de Condiciones de Trabajo del Instituto Nacional de Seguridad e Higiene en el trabajo de España (INSHT) que permite recolectar información sobre la caracterización de la población a nivel sociodemográfico y ocupacional, y para la determinación de patologías dermatológicas relacionadas con el trabajo se utilizó el Cuestionario NOSQ-2002 Nórdico- Enfermedades Cutáneas de origen Laboral, en su versión validada en español. Se describieron las variables categóricas con porcentajes y las continuas (cuantitativas) con medidas de tendencia central y dispersión La asociación entre los hallazgos de exposición ocupacional y los síntomas y signos en piel, fue estimada mediante riesgos relativos. RESULTADOS El 75,4% del total de la población correspondió al género masculino y el 67,5% reportó realizar sus labores como trabajadores independientes. Respecto a la identificación de condiciones de salud, la percepción por parte de los orfebres fue positiva, reportando muy buena salud en el 34% de los mismos. El 8% de la población manifestó alteraciones dermatológicas tipo eczema en los últimos seis meses y el 11% las presentó principalmente en manos. Respecto de la iniciación del eczema, el 97% de los trabajadores reportó que se iniciaba al contacto con sustancias químicas y el 98,7% manifestó que se encontraban realizando la labor de orfebrería cuando inició el eczema. La lesión prevalente fue mancha roja sin edema (8%), seguida de ronchas o manchas y ampollas pequeñas (3%) y de piel seca con escamas (2%). CONCLUSIONES Los resultados de la presente investigación mostraron la prevalencia de alteraciones cutáneas principalmente en las manos, tipo eczema (manchas rojas) o prurito (picor). Se recomienda la disminución de los tiempos de exposición, adecuación de jornadas y tiempos de descanso, sistemas de protección personal adecuados y la implementación de un programa de educación y participación para el control integral del riesgo.

Uncertified absence from work and the Big Five:an examination of absence records and future absence intentions

Uncertified absence from work has traditionally been difficult to link to personality. The present paper argues that personality is best conceptualized as influencing an individual’s intention to be absent from work because of reasons that are within their control. This was investigated in an employed community sample of 128 individuals. These individuals used a self-report measure to express their future intentions to be absent from work as a result of several reasons. These reasons for absence were categorized as “being absent because of external pressure or commitment” (ABCo) and “being absence by choice” (ABCh). The Big Five personality factors were found to be unrelated to objective uncertified absence records and unrelated to ABCo. Three of the Big Five were related to ABCh. Agreeableness was negatively related to ABCh whereas Extraversion and Openness demonstrated a positive correlation. It was concluded that the results should be viewed tentatively, but that this study may provide a useful framework for conceptualizing the association of personality with uncertified absence.

Expression of heterochromatin protein 1 in the primary tumor of breast cancer patients in the presence or absence of occult metastatic cells in the bone marrow

Gene silencing may occur in breast cancer samples from patients presenting with occult metastatic cells in the bone marrow and one mechanism regulating gene suppression is heterochromatin formation. We have studied whether members of the heterochromatin protein 1 family Hp1(Hs alpha), Hp1(Hs beta) and Hp1(Hs gamma) which take part in chromatin packaging and gene expression regulation, were differentially expressed in tumors from patients with and without occult metastatic cells in their bone marrow. Tumor samples and bone marrow aspirates were obtained from 37 breast cancer patients. Median age was 63 years and 68% of the patients presented with clinical stage I/II disease. Presence of occult metastatic cells in bone marrow was detected through keratin-19 expression by nested RT-PCR in samples from 20 patients (54.1%). The presence of occult metastatic cells in bone marrow was not associated with node involvement, histological grade, estrogen receptor and ERBB2 immunoexpression. Relative gene expression of HP1(Hs alpha), HP1(Hs beta) and HP1(Hs gamma) was determined by real-time RT-PCR and did not vary according to the presence of occult metastatic cells in bone marrow. In addition, the combined expression of these three transcripts could not be used to classify samples according to the presence of bone marrow micrometastasis. Our work indicates that regulation of heterochromatin formation through HP1 family members may not be the sole mechanism implicated in the metastatic process to the bone marrow.

Absence of functional TLR4 impairs response of macrophages after Candida albicans infection

Candida albicans is recognized by phagocytic cells through a set of recognition receptors patterns. Recently, we showed the importance of TLR2 in the regulation of neutrophil survival after C. albicans infection. In the present work, we analyzed the involvement of TLR4 in the recognition of C. albicans by neutrophils and macrophages. Our results show that the absence of functional TLR4 resulted in lower chemotaxis of neutrophils to the site of infection, lower levels of TNF-alpha, CXCL1 and nitric oxide, and dissemination and persistence of the pathogen in lymph nodes and spleen. In vitro, the phagocytic activity, nitric oxide production and myeloperoxidase activity, CXCL1, IL-1 beta production by neutrophils from TLR4-defective mice were not changed. In contrast, macrophages from TLR4-defective mice demonstrated lower phagocytosis and lower levels of CXCL1, IL-1 beta and TNF-alpha. Together, these data demonstrate that TLR4 signals are important for the recognition of C. albicans by macrophages and their absence allows persistence of the infection.

Motivations and management factors of volunteer work in nonprofit organisations: a literature review

The objective of this paper is to review and discuss the literature about volunteers’ motivations to donate their time to NPOs and the management factors that can influence volunteer work. Firstly, the paper illustrates and compares the different types of motivation followed by a presentation of a typology that organises the volunteers’ motivations into four types: (i) altruism, (ii) belonging, (iii) ego and social recognition and (iv) development and learning. Secondly we discuss the key management factors in volunteering: recruitment, training and rewarding. Finally, we present four gaps in the literature that justify the scope for further research: (i) omission of differences between motivations related to volunteers’ "Attraction" versus "Retention"; (ii) focus of the research on the USA, UK and Australia context; (iii) absence of comparative analyses that relate motivations by NPO types and (iv) comprehension of how management factors (recruitment, training and rewarding) influence volunteers’ satisfaction and retention.

Absence of Fas-L aggravates renal injury in acute Trypanosoma cruzi infection

Trypanosoma cruzi infection induces diverse alterations in immunocompetent cells and organs, myocarditis and congestive heart failure. However, the physiological network of disturbances imposed by the infection has not been addressed thoroughly. Regarding myocarditis induced by the infection, we observed in our previous work that Fas-L-/- mice (gld/gld) have very mild inflammatory infiltration when compared to BALB/c mice. However, all mice from both lineages die in the early acute phase. Therefore, in this work we studied the physiological connection relating arterial pressure, renal function/damage and cardiac insufficiency as causes of death. Our results show that a broader set of dysfunctions that could be classified as a cardio/anaemic/renal syndrome is more likely responsible for cardiac failure and death in both lineages. However, gld/gld mice had very early glomerular deposition of IgM and a more intense renal inflammatory response with reduced renal filtration, which is probably responsible for the premature death in the absence of significant myocarditis in gld/gld.

Work Meaningfulness as a Key Enhancer of Ethical Values in Business

Despite abundant research on work meaningfulness, the link between work meaningfulness and general ethical attitude at work has not been discussed so far. In this article, we propose a theoretical framework to explain how work meaningfulness contributes to enhanced ethical behavior. We argue that by providing a way for individuals to relate work to one's personal core values and identity, work meaningfulness leads to affective commitment - the involvement of one's cognitive, emotional, and physical resources. This, in turn, leads to engagement and so facilitates the integration of one's personal values in the daily work routines, and so reduces the risk of unethical behavior. On the contrary, anomie, that is, the absence of meaning and consequently of personal involvement, will lead to lower rational commitment rather than affective commitment, and consequently to disengagement and a-morality. We conclude with implications for the management of ethical attitudes.
