Introduction: Brazil leads the production of sugarcane and its derived commodities, sugar and ethanol. The fact that it is predominantly manually harvested exposes the workers to a variety of health hazards. Since the harvest is a labor activity that exacts from the worker a heavy physical toll, involving the exertion of quick, repetitive movements that intensely overburden both one’s muscles and skeletal frame. Objective: To assess the health profile and functional independence in former workers who operated in a biofuel plant in Bahia. Methods: This is a descriptive, exploration-oriented study conducted with 42 workers formerly employed as cane cutters, both male and female and over 18 years old, all of them living in the town of Amélia Rodrigues (BA). The self-administered Nottingham Health Profile (NHP) was used to measure their quality of life, based on the World Health Organization’s classification of disabilities;the Functional Independence Measure (FIM) metrics was employed to keep track of functional independence. The FIM focuses on two aspects, motile and cognitive, subdivided further into categories designed to assess individual independence in tackling basic activities effectively and satisfactorily. Results: 42 individuals were assessed, most of them men (54.8%), predominantly adults (73.8%) of African descent (61.9%). Evidence, along with the correlation coefficient to analyze the FIM and the NHP, presents a significance level of 0.05 in the categories: Total NHP, Energy Level, Pain and Physical Abilities. Conclusion: This study found that there is harm to the health of former cane cutters as far as their sleep, energy levels and physical abilities are concerned. With these remarks, the authors expect to motivate health surveillance efforts regarding the risks in those work environments and the associated health issues, so that preventive and interventive public health measures can be implemented.

Occupational Diseases and Environmental Medicine 2018年第2期6卷 62-70页

作者： Kaliane Pamponet Prazeres Bomfim jaqueline silva veloso Mabel Barbosa Esteves Center for Biomedical Research College of Technology and Science-FTC Salvador Brazil

Background: Large-scale cane cultivation can promote health impacts of workers, resulting from weight bearing and repetitive movements. Musculoskeletal conditions can alter balance and increase risk of falls. Aim of Work: The objective of this study is to identify clinical characteristics and to correlate balance with functional capacity in ex-cane cutters. Methods: This was a descriptive exploratory study, 42 former workers of the cane cut, with mean age of 49 (±13) years, who were submitted to balance evaluation through the Berg Balance Scale (BSE) and the functional capacity was evaluated by the Incremental Shuttle Walk Test (ISWT). To investigate respiratory symptoms, the Medical Research Council questionnaire was used. Results: The individuals reached a mean of 52 points in BSE, considered low to moderate risk for falls and the average distance traveled of 446.2 (±188.5) meters, corresponding to 52.9% (±23.1) of the normal distance. Weak and negative correlations were found between changes in balance and exposure time (r2-0.16). Conclusion: It is concluded that excessive physical effort contributes to changes in the balance and, consequently, diminish functional capacity.

Motivational and Methodological Factors Involved in the Helping Behavior Test in Laboratory Rodents

Journal of Behavioral and Brain Science 2024年第8期14卷 240-254页

Empathy allows humans and other animals to share the emotional state of another, adopting that individual’s perspective on a given situation. This ability is fundamental for species living in groups. Helping behavior in laboratory animals has been used to study empathy. In this test, subjects are exposed to a conspecific that is trapped and learn to open the cage to release the other animal. However, the interpretation of helping behavior as an emphatically motivated action is still controversial. Here we review the studies that use the helping behavioral test proposed by Ben-Ami Bartal and colleagues in 2011 to better understand motivational factors for this behavior. In addition, we compare methodological aspects of these studies. In conclusion, helping behavior can be driven by empathy, but other factors such as the desire for social contact and learning components cannot be ruled out as motivators. In addition, studies focused on evaluating neurobiological mechanisms underlying helping behavior in laboratory rodents can help elucidate the factors involved in releasing the trapped co-specific.

Multiple regression analyses were ***: Participating adolescents(n = 567, 53% female, 12.9 ± 5.3 years) spent 5% of school time in MVPA and 27% in LPA, 15% of recesses in MVPA and 44% in LPA, and 16% of PE classes in MVPA and 41% in LPA. Boys engaged in more MVPA in all categories. Age was inversely related with MVPA and LPA in all periods, whereas body fat percentage was inversely related with MVPA in school time and PE classes. Attitude was inversely related with MVPA in all periods and with LPA in recesses. Considering PA to be good and enjoyable was positively associated with MVPA in school ***: Adolescents spent little time in PA during school. Future interventions should implement enjoyable activities at school.

Intra-abdominal infections can be classified into uncomplicated or complicated(peritonitis). Peritonitis is divided into primary, secondary, and tertiary. Tertiaryperitonitis is the less common but the most severe among peritonitisstratifications, being defined as a recurrent intra-abdominal infection that occurs48 h after a well-succeeded control of a secondary peritonitis. This disease has acomplex pathogenesis that is closely related to the capacity of the peritonealcavity to activate immunological processes. Patients who progress to persistentperitonitis are at an increased risk of developing several infectious complicationssuch as sepsis and multiple organ failure syndrome. Moreover, tertiary peritonitisremains an important cause of hospital death mainly among patients withassociated risk factors. The microbiological profile of organisms causing tertiaryperitonitis is often different from that observed in other types of peritonitis. Inaddition, there is a high prevalence of multidrug-resistant pathogens causing thiscondition, and an appropriate and successful clinical management depends on anearly diagnosis, which can be made easier with the use of clinical scorespresenting a good prediction value during the intensive care unit ***, immediate therapy should be performed to control theinfectious focus and to prevent new recurrences. In this sense, the treatment isbased on initial antimicrobial therapy and well-performed peritoneal drainage.

Selenium is an element which participates in antioxidant enzymes. A medium and long term lack of such element is associated, mainly, with heart disease, joint and bone structure problems and thyroid activity. Selenium contents in blood reflect its ingestion and food content variation. It depends on soil characteristics, such as pH and selenium presence. There are few studies concerning selenium levels in food and blood in Brazil. Therefore, the objective of this research was to determine selenium content in a blood donor group in Rio de Janeiro state, conducted from December 2008 to March 2009. From the donated blood to Regional Blood Center of Campos dos Goytacazes, 4.0 mL were submitted to selenium analysis through atomic absorption spectrometry of hydride generation and organic matter oxidation wet basis with nitric and perchloric acid. Selenium content varied from 75 ± 16 ng·g-1 for females and 70 ± 21 ng·g-1 for males. There was no significant difference among selenium contents in blood from donors of different gender, age and residence. Seventy four percent of donors had selenium content in blood below 70 ng·mL-1, the lowest level for maximum selenoproteins production, according to the Nutritional Prevention Cancer.
