Fontoura-Junior EE, Magalhães Guimarães LA. Work, health and disease among rural workers in wetlands: integrative review. Rev Bras Med Trab 2020; 17:402-414. [PMID: 32368675 PMCID: PMC7195880 DOI: 10.5327/z1679443520190311] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2018] [Accepted: 04/30/2019] [Indexed: 11/05/2022] Open
Abstract
Rural workers represent the typical population of workers in the Brazilian Pantanal, their work environment being characterized by exuberant fauna and flora, but also countless hazards. The aim of the present study was to analyze work, health and disease aspects of rural workers in Pantanal and the corresponding risk factors. It consists in an integrative review of studies published from 2006 to 2016 located in databases Regional Library of Medicine (BIREME), Latin American and Caribbean Health Sciences Literature (LILACS), Scientific Electronic Library Online (SciELO), MEDLINE, PubMed, Periódicos Eletrônicos em Psicologia (PePSIC), the journal portal and dissertation database of the Brazilian Federal Agency of Support and Evaluation of Graduate Education (CAPES), dissertation databases of Universidade Estadual de Campinas, Universidade de São Paulo, Universidade Católica Dom Bosco (Campo Grande, Mato Grosso do Sul) and Universidade Federal do Mato Grosso do Sul, and Google Scholar. We retrieved 27 publications, being 18 scientific studies, 2 PhD and 5 MA dissertations and 2 e-books. Evidenced hazards include accidents involving animals, work overload, and exposure to weather conditions, viruses, bacteria and chemicals, among others. The results point to the need to implement actions considered in public policies for prevention, health promotion and recovery, with particular focus on safety and health at work.

Portilho MM, Mendonça A, Marques VA, Nabuco LC, Villela-Nogueira CA, Ivantes C, Lewis-Ximenez LL, Lampe E, Villar LM. Comparison of oral fluid collection methods for the molecular detection of hepatitis B virus. Oral Dis 2017; 23:1072-1079. [PMID: 28544047 DOI: 10.1111/odi.12692] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2017] [Revised: 04/09/2017] [Accepted: 05/11/2017] [Indexed: 12/14/2022]
Abstract
BACKGROUND This study aims to compare the efficiency of four oral fluid collection methods (Salivette, FTA Card, spitting and DNA-Sal) to detect HBV DNA by qualitative PCR. MATERIALS AND METHODS Seventy-four individuals (32 HBV reactive and 42 with no HBV markers) donated serum and oral fluid. In-house qualitative PCR to detect HBV was used for both samples and commercial quantitative PCR for serum. RESULTS HBV DNA was detected in all serum samples from HBV-infected individuals, and it was not detected in control group. HBV DNA from HBV group was detected in 17 samples collected with Salivette device, 16 samples collected by FTA Card device, 16 samples collected from spitting and 13 samples collected by DNA-Sal device. Samples that corresponded to a higher viral load in their paired serum sample could be detected using all oral fluid collection methods, but Salivette collection device yielded the largest numbers of positive samples and had a wide range of viral load that was detected. CONCLUSION It was possible to detect HBV DNA using all devices tested, but higher number of positive samples was observed when samples were collected using Salivette device, which shows high concordance to viral load observed in the paired serum samples.

Abstract
PURPOSE OF REVIEW This review discusses the utility of pathogen-specific antibody biomarkers for improving estimates of the population burden of waterborne infections, assessing the fraction of infections that can be prevented by specific water treatments, and understanding transmission routes and the natural history and ecology of disease in different populations (including asymptomatic infection rates). RECENT FINDINGS We review recent literature on the application of pathogen-specific antibody response data to estimate incidence and prevalence of acute infections and their utility to assess the contributions of waterborne transmission pathways. Advantages and technical challenges associated with the use of serum versus minimally invasive salivary antibody biomarkers in cross-sectional and prospective surveys are discussed. We highlight recent advances and challenges and outline future directions for research, development, and application of antibody-based and other immunological biomarkers of waterborne infections.
