Sleep, ageing and night work

Aging and physical inactivity are two factors that favors the development of cardiovascular disease, metabolic syndrome, obesity, diabetes, and sleep dysfunction. In contrast, the adoption a habitual of moderate exercise may present a non-pharmacological treatment alternative for sleep and metabolic disorders. We aimed to assess the effects of moderate exercise training on sleep quality and on the metabolic profile of elderly people with a sedentary lifestyle. Fourteen male sedentary, healthy, elderly volunteers performed moderate training for 60 minutes/day, 3 days/week for 24 wk at a work rate equivalent to the ventilatory aerobic threshold. The environment was kept at a temperature of 23 ± 2°C, with an air humidity 60 ± 5%. Blood and polysomnographs analysis were collected 3 times: at baseline (1 week before training began), 3 and 6 months (after 3 and 6 months of training). Training promoted increasing aerobic capacity (relative VO2, time and velocity to VO2max; p < 0.05), and reduced serum NEFA, and insulin concentrations as well as improved HOMA index (p < 0.05), and increased adiponectin levels (p < 0.05), after 3 months of training when compared with baseline data. The sleep parameters, awake time and REM sleep latency were decreased after 6 months exercise training (p < 0.05) in relation baseline values. Our results demonstrate that the moderate exercise training protocol improves the sleep profile in older people, but the metabolism adaptation does not persist. Suggesting that this population requires training strategy modifications as to ensure consistent alterations regarding metabolism.

In Brazil, research on pulmonology has become increasingly more visible in recent years. In addition to the Brazilian Journal of Pulmonology, other journals have contributed to that by publishing relevant articles in this area. The objective of this article was to briefly report the most relevant studies on pulmonology that were published in other important Brazilian journals between 2009 and 2010. Altogether, there were 56 articles related to the various subareas that compose the field of respiratory diseases.Keywords: Pulmonary medicine; Research; Brazil. ResumoA pesquisa em pneumologia no Brasil tem apresentado progressivo destaque nos últimos anos e, além do Jornal Brasileiro de Pneumologia, outros periódicos têm contribuído com a publicação de manuscritos relevantes nessa área.

“…Ao estudar a relação de trabalho por turnos e noturno com as patologias do sono, estudiosos publicaram a influência destes na sociedade moderna, alterando os meios de produção e da organização do trabalho nas indústrias e mudando de forma drástica o estilo de vida, a saúde e o bemestar dos colaboradores 3 . Também mencionaram que turno contínuo e prolongado principalmente a noite predispõe os trabalhadores a doenças cardiovasculares, gastrointestinais e estresse psicossocial.…”

“…Trabalhadores são rotineiramente submetidos à privação parcial crônica do sono devido ao desacordo recorrente entre o tempo de serviço e os horários fisiológicos de dormir. Sono mais curto e mais fragmentado implica em sonolência excessiva, fadiga mental, irritabilidade e redução do desempenho, que muitas vezes são fatores de risco para acidentes laborais 3 .…”

Rev Med (São Paulo RESUMO:Caminhoneiros tipicamente têm horários de trabalho irregulares e devem freqüentemente inverter o ciclo vigília-sono, levando a privação parcial de sono cronicamente. Esta situação predispõe a elevados níveis de estresse, ao uso abusivo de drogas e psicoestimulantes, aos distúrbios alimentares, ao sedentarismo e ao desenvolvimento de doenças crônicas. Este estudo teve por objetivo revisar os distúrbios de sono e as alterações neurocomportamentais nesta população. Os autores realizaram uma discussão de 38 artigos selecionados nas bases de dados Medline, Cochrane Library, Lilacs e SciELO, usando como descritores transtornos do sono, condução de veículo, manifestações comportamentais no período de 1997 a 2010. Os autores enfatizaram neste trabalho os aspectos epidemiológicos, os fatores relacionados, os protocolos de avaliação, os instrumentos usados, as modalidades de tratamento, os distúrbios neurocomportamentais associados e as repercussões no trabalho, na saúde e na sociedade. Uma avaliação completa por profissionais capacitados na área de saúde ocupacional é fortemente recomendada na admissão, exames periódicos e na demissão destes funcionários. Faz necessário mais estudo para delinear quais os tipos de protocolos mais úteis na prática clínica, a fim de desenvolver estratégias de tratamento que contemple as necessidades destas pessoas. DESCRitORES:Transtornos do sono; Manifestações neurocomportamentais; Condução de veículo; Veículos automotores. ABStRACt:Truck drivers have typically irregular working hours and they must frequently reverse the sleep-wake cycle which leads them to a chronic partial sleep privation. This situation tpredispose them to high levels of stress, to the use of psycho stimulants and drugs to eating disorders and to sedentarism and the development of chronic diseases. This study aimed to review the sleep-wake cycle and the neurobehavioral changes in this population. The authors performed a discussion of 38 selected articles on Medline, Cochrane Library, Scielo and Lilacs, based on descriptors such as sleep disorders, vehicle driving, behavioral manifestations during the period 1997 to 2010. The authors emphasized on this study epidemiological aspects related factors, the evaluation protocols, instruments used, methods of treatment to neurobehavioral disorders and their impact on labor, health and society. A full analysis to look for qualified professionals in the field of occupational health is strongly recommended for admission, periodic examinations and for a dismissal of those employees. More study is needed to delineate which types of protocols most be useful in clinical practice, to develop treatment strategies that addresses the needs of this population.
