Prevalence of and Factors Associated with Actinic Cheilitis in Extractive Mining Workers.

The objective of the present study was to determine the prevalence of actinic cheilitis among extractive mining workers and factors associated with the condition, especially the relationship between clinical appearance and the length of occupational exposure to sunlight. A cross-sectional study was performed in Dona Inês, Paraíba, Brazil between 2014 and 2015. A clinical examination, clinical photography and a questionnaire were applied to 201 extractive mining workers. The T-student's, ANOVA one-way, Fisher's exact and Pearson chi-squared tests were performed and the significance level was set at 5%. A high prevalence of actinic cheilitis was observed (38.8%). Length of occupational exposure to sunlight in months (169.63±112.68, p=0.002) was associated with actinic cheilitis. Most workers were Caucasian (p<0.001) and aged 37.41±12.15 years (p=0.004). The time of occupational exposure to sunlight was significant in relation to the following clinical features: atrophy (225.75±97.31; p=0.024); blurred demarcation between the vermilion border of the lip and the skin (186.68±113.15; p=0.032); vertical fissures (210.09±123.07; p=0.046); white and red spotting (199.51±91.80; p=0.004); hard consistency of the lip (225.81±122.34; p=0.012). A high prevalence of actinic cheilitis was found. Age and ethnicity were associated with the presence of AC. Severe clinical presentations of actinic cheilitis were found among participants who had worked for at least 185 months (approximately 15 years) exposed to the sun.

Intestinal parasitic infections among expatriate workers in various occupations in Sharjah, United Arab Emirates.

Intestinal parasitic infections are prevalent throughout many countries. This study aimed to determine the prevalence of intestinal parasite carriers among 21,347 expatriate workers, including food handlers and housemaids attending the public health center laboratory in Sharjah, UAE. Stool sample collection was performed throughout the period between January and December 2013. All samples were examined microscopically. Demographic data were also obtained and analyzed. Intestinal parasites were found in 3.3% (708/21,347) of the studied samples (single and multiple infections). Among positive samples, six hundred and eighty-three samples (96.5%) were positive for a single parasite: Giardia lamblia (257; 36.3%) and Entamoeba histolytica/Entamoeba dispar (220; 31.1%), respectively, whereas mono-infections with helminths accounted for 206 (29.1%) of the samples. Infection rates with single worms were: Ascaris lumbricoides (84; 11.9%), Hookworm (34; 4.8%), Trichuris trichiura (33; 4.7%), Taenia spp. (27; 3.81%), Strongyloides stercoralis (13; 1.8%), Hymenolepis nana (13; 1.8%), and Enterobius vermicularis (2; 0.28%), respectively. Infections were significantly associated with gender (x2 = 14.18; p = 0.002) with males as the most commonly infected with both groups of intestinal parasites (protozoa and helminths). A strong statistical association was noted correlating the parasite occurrence with certain nationalities (x2= 49.5, p <0.001). Furthermore, the study has also found a strong statistical correlation between parasite occurrence and occupation (x2= 15.60; p = 0.029). Multiple infections were not common (3.5% of the positive samples), although one individual (0.14%) had four helminth species, concurrently. These findings emphasized that food handlers with different pathogenic parasitic organisms may pose a significant health risk to the public.

Occupational Deprivation or Occupational Adaptation of Mexican Americans on Renal Dialysis.

The aim of this study was to explore the occupational changes and perceptions experienced by Mexican Americans with end-stage renal disease (ESRD) and their families living with dialysis. In-depth interviews were conducted with 17 Mexican Americans with ESRD and 17 family members. The participants with ESRD described altered or lost activity patterns, capacities and freedoms. With a heightened awareness of death, the family members made altered occupational choices, which were consistent with their cultural values. Changes in the physical body, adhering to the dialysis regimen and environmental restrictions created barriers to occupational participation. These findings suggest that living with dialysis facilitate occupational deprivation among individuals with ESRD and adaption among the family members within cultural alignments. This phenomenon could affect the design of occupational therapy intervention and call for research on the role of occupation therapy services with this population.

Urban occupational health in the Mexican and Latino/Latina immigrant population: a literature review.

Mexican and Latino/Latina immigrants represent a rapidly growing population within the United States. The majority settle in urban areas. As a group, Mexican immigrants typically have low educational attainment and socioeconomic status, and limited English proficiency. These immigrants often find work in hazardous jobs, with high injury and fatality rates. They often have inadequate or no safety training, no personal protective equipment, limited understanding of workers' rights, job insecurity, fear of report of undocumented status and lack health care benefits. This review includes what has been published on the urban occupational health of this population. The findings suggest that Mexican and Latino/Latina immigrants experience higher rates of work-related fatalities and injuries compared to other populations, and may be less likely to report such incidents to employers or to apply for workers' compensation. There is a strong need to develop effective programs to address the health and safety of this vulnerable population.

Occupational health profile of Brazilian immigrant housecleaners in Massachusetts.

The occupational health and safety conditions of a sample of Brazilian housecleaners in Massachusetts are examined in this article. We administered a main survey to a convenience sample of 626 Brazilian immigrant workers of all trades and a supplemental survey to 163 Brazilian housecleaners in Massachusetts in 2005 and 2006. Survey questions addressed housecleaner demographics, socioeconomic status, working conditions, and hazards of housecleaning work. Housecleaners are exposed to a variety of ergonomic, chemical, and biological hazards. Professional housecleaners' work is fast-paced, requires awkward postures, and involves repetitive movements, use of force, and heavy lifting. The most common symptoms reported include back pain, and pain in the muscles, arms, legs, neck, shoulder, hands, fingers, and feet. To reduce exposures to occupational hazards, we propose the substitution of green cleaners for toxic chemical cleaning products, the use of ergonomic equipment, the use of personal protective equipment, and changes in work organization.

Mexican urban occupational health in the US: a population at risk.

Mexicans are the largest immigrant group in the US. Little is known about their urban occupational health status. We assess occupational illness, injury, and safety training among New York City Mexican immigrants. This study is a consecutive sample of the Mexican immigrant population utilizing Mexican Consulate services in New York City over two weeks in March 2009. Bilingual research assistants approached persons waiting in line at the Consulate and administered an occupational health questionnaire. 185 people agreed to participate. Most work in restaurants (37%), cleaning (18%), construction (12%), babysitting/nanny (7%), retail (9%), and factories (5%). 22% had received safety training. 18% reported work-related pain or illness. 18% suffered from a job-related injury since immigrating. Most injuries were in construction, factories, and restaurants. 29% had not reported their injury. This study provides evidence that the urban Mexican immigrant population is at high risk for work-related illness and injury, is not receiving adequate safety training, and is under-reporting occupational injury. Culturally and linguistically responsive community outreach programs are needed to provide occupational health and safety information and resources for urban Mexican workers.

Peripheral and central auditory dysfunction induced by occupational exposure to organic solvents.

OBJECTIVE: To examine the effects of solvent exposure on hearing function, through an audiological test battery, in a population not occupationally exposed to high levels of noise. METHODS: One hundred ten workers from a coating factory were studied. Jobs at the factory were divided into three different levels of solvent exposure. Hearing status was assessed with a test battery including pure-tone hearing thresholds (0.5-8 kHz), high-frequency hearing thresholds (12 and 16 kHz), and dichotic listening measured through dichotic digits test. Multiple linear regression models were created to explore possible association between solvent exposure and each of the hearing outcomes. RESULTS: Significant associations between solvent exposure and the three hearing outcomes were found. Covariates such as age, gender, race, and ethnicity were also significantly associated with the studied hearing outcomes. CONCLUSIONS: Occupational exposure to solvents may induce both peripheral and central auditory dysfunction. The dichotic digits test seems as a sensible tool to detect central auditory dysfunction associated with solvent exposure. Hearing loss prevention programs may use this tool to monitor hearing in solvent-exposed workers.

Aspectos psicossociais do impedimento laboral por motivos de saúde em trabalhadores de cozinhas industriais / Psychosocial aspects of labor impediment by health reasons in industrial kitchens workers

Este estudo teve por objetivo investigar a relação trabalho / saúde em trabalhadores de cozinhas industriais, focalizando o aspecto socioeconômico e outras dimensões da vida social (estresse no trabalho e eventos de vida produtores de estresse), incluindo-se morbidade (obesidade, doenças crônicas e transtornos mentais comuns), condição laboral (incômodos ambientais e acidentes de trabalho) e comportamentos relacionados à saúde (consumo alimentar, tabagismo e álcool). Utilizando dados coletados nos nove restaurantes populares do Estado do Rio de Janeiro, apresentam-se três artigos. O primeiro descreve a população de estudo, considerando três grupos ocupacionais: administrativos, cozinheiros e copeiros, e os auxiliares de serviços gerais. O segundo artigo investiga a associação entre as características psicossociais e o impedimento laboral por motivos de saúde, considerando uma análise hierarquizada e, finalmente, o terceiro artigo discute a certificação da reprodutibilidade, na população de estudo, do questionário sueco da versão para o português do Demand-Control Questionnaire (DCQ), utilizado para avaliar estresse no ambiente de trabalho.

Masculinity and undocumented labor migration: injured latino day laborers in San Francisco.

Drawing on data collected through clinical practice and ethnographic fieldwork, this study examines the experience of injury, illness and disability among undocumented Latino day laborers in San Francisco. We demonstrate how constructions of masculine identity organize the experience of embodied social suffering among workers who are rendered vulnerable by the structural conditions of undocumented immigrant status. Theoretical concepts from critical medical anthropology and gender studies extend the scholarly analysis of structural violence beyond the primarily economic to uncover how it is embodied at the intimate level as a gendered experience of personal and familial crisis, involving love, respect, betrayal and patriarchal failure. A clinical ethnographic focus on socially structured patriarchal suffering elucidates the causal relationship between macro-forces and individual action with a fuller appreciation of the impact of culture and everyday lived experience.

Illness, injury, and disability among Shiwiar forager-horticulturalists: implications of health-risk buffering for the evolution of human life history.

Human life history is distinguished by long lifespan, delayed reproduction, intergenerational asymmetric benefit transfers from adults to juveniles and between adults, and a large brain able to engage in unprecedented levels of learning, reasoning, and insight. The evolution of these traits depends on relatively low human mortality. Understanding why humans have low mortality is therefore critical for understanding the evolution of key human traits. One explanation is that the evolution of food provisioning during periods of health crisis reduced mortality. This hypothesis turns on health risk having posed a significant adaptive problem that could be effectively buffered by healthcare provisioning. Unfortunately, the frequency, duration, and fitness effects of temporary disability are difficult to estimate based on osteological evidence alone, and systematic ethno-biological research on these issues among extant small-scale societies with little access to Western medical care is lacking. Here I present data on 678 injuries and illnesses suffered by 40 Shiwiar forager-horticulturalists, based on physical evidence and informant reports. A subsample of 17 individuals provided data on incidence and duration of disability for 215 pathological incidents. Results indicate that injury and illness occur frequently across the lifespan. Most living individuals have suffered temporarily disabling health crises likely to have been lethal without provisioning. The fitness effects of surviving these episodes are high, suggesting that the Shiwiar population structure and lifeway are dependent on infrequent extended provisioning to temporarily disabled individuals, and that provisioning of aid during healthcare crises effectively lowers mortality in this small-scale society.

Explaining Mexican American workers' hearing protection use with the health promotion model.

BACKGROUND: Mexican American workers are vulnerable to noise-induced hearing loss, the most common occupational disease in the United States. OBJECTIVES: The purpose was to test the applicability of the Health Promotion Model to Mexican American workers' use of hearing protection devices. METHOD: A correlational descriptive design and path analysis were used to determine the relationships between cognitive-perceptual factors, modifying factors and use of hearing protection devices. A questionnaire was completed by a total of 119 workers in three garment manufacturing plants. Interviews were conducted with the occupational health nurse or safety director in each plant to determine the policy regarding hearing protection also. RESULTS: Factors that directly influenced the use of hearing protection devices were a clinical definition of health, benefits of and barriers to use of hearing protection devices, self-efficacy in the use of hearing protection devices and perceived health status (R2 =.25, p <.01). An exploratory analysis allowing a direct relationship of modifying factors with the dependent variable explained additional variance in use of hearing protection devices through the contribution of situational factors (R2 =.55, p <.01). CONCLUSIONS: Important factors related to Mexican American workers' use of hearing protection devices were identified to provide direction for nursing interventions. Future research should further test the explanatory capabilities of the Health Promotion Model, explore the importance of situational influences on health behavior, and ensure reliable measures of all model components for this population.

Epidemiology of coccidioidomycosis.

Coccidioides immitis naturally occurs in the soil and air of certain areas of the New World. These are generally arid to semiarid areas that have relatively modest rainfall, mild winters, and prolonged hot seasons. Coccidioidomycosis is usually a disease of human and nonhuman residents of these areas; but visitors may develop the disease after entering these areas and returning home long distances from the endemic areas. Inhalation (rarely percutaneous introduction) of arthroconidia of C. immitis leads to usually benign but occasionally severe and even fatal infection. Recovery from or asymptomatic infection leads to resistance to reinfection. Exposure to soil (dust) means that certain occupations are more likely to be exposed to C. immitis. Persistence of the organism in the soil means that infections will be encountered in the future, particularly as long as susceptible newcomers continue to enter endemic areas. Those who have been infected and recovered generally will be resistant to later infection, although exacerbation may occur as a result of superimposed immunosuppression.

Prevalence of antibody to hepatitis B virus in foreign-born hospital employees.

Hepatitis B surface and core antibodies were measured in 512 community hospital employees at increased risk for developing infection with hepatitis B virus. Antibody was detected in 140 (27 percent) participants. Multivariate logistic regression analysis indicated that seropositivity was strongly associated with the prevalence of hepatitis B in an employee's country of birth and with age. These results suggest that reported differences among hospitals in hepatitis B seropositivity may in part be a reflection of the national origin of its employees. These data also indicate that each hospital should assess its own risk for hepatitis B infection and that prevaccination serologic testing is particularly worthwhile in hospitals having large numbers of foreign-born employees.
