In the European Union, it is the first work-related cause of death. Studies about occupational risk exposure are a useful field of investigation to determine cancerous elements; special attention is paid to the relationship between cancer and work in women, who must constantly adapt to the working market and the new working fields, with their diverse degrees of exposure to risks. This revision has reviewed the bibliography gathered in Medline related to breast cancer, cervix cancer, uterus cancer, and ovarian cancer, along with their relationship with different work-related risks and types of working roles. The results have shown enough scientific evidence to suspect that work related exposition could be a plausible cause of these gynaecological cancers. Therefore, we want to stress the need of enhancing the coordinated investigation between all the medical specialties involved, and to encourage the spread of the necessary knowledge to manage and prevent them.","PeriodicalId":71955,"journal":{"name":"职业病与环境医学(英文)","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45836746","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective of this study is to describe the prevalence and patterns of COVID-19 infection in HCWs amongst a group of patients receiving care for COVID-19 in Rivers state, Nigeria. Methods: This study was a prospective descriptive study of all consenting patients who received care through hospitals, designated for COVID-19 treatment in Rivers state either as in-patient or out-patient following a laboratory-confirmed diagnosis of COVID-19 based on a positive SARS-CoV-2 RT-PCR from April to September 2020. Results: A total number of 646 COVID-19 patients were enrolled over the study period with 98 (15.2%) HCWs in the patient population. The HCWs with COVID-19 consisted largely of Doctors 47 (47.9%), Nurses 30 (30.6%), and socio-sanitary and hygiene workers 10 (10.2%). There were 46 (46.9%) female HCWs, compared to Non-HCWs with 112 (21.1%), females, p = 0.000. Sixty-eight (69.4%) HCWs had a source of contact for infection established compared to Non-HCWs with an established source of contact in 181 (34.2%), p = 0.000. Eight (8.2%) HCWs had Severe disease compared to 52 (9.8%) Non-HCWs with severe disease, p = 0.670. The case fatality in HCWs was 1% compared to 1.9% in Non-HCWs, p = 0.554. Conclusion: The prevalence of COVID-19 among HCWs in the study location is high with clinical and clinical support staff particularly, doctors and nurses are at higher risk of COVID-19 infection. This calls for action to improve and prevent HCWs infections in hospital settings in addition to improving HCW infection prevention behaviour in the community. The intensification of risk communication, provision of protective equipment (PPE), and training on the appropriate use of PPE; in addition to routine surveillance for infection is recommended.","PeriodicalId":71955,"journal":{"name":"职业病与环境医学(英文)","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45948197","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a result of efforts to control direct (person to person) and indirect (contaminated objects, surfaces, indoor air) transmission of the virus, various interventions have been evaluated. Studies were conducted to evaluate the efficacy of commercially available chlorine dioxide (CD) products to reduce viral loads on PPE (face masks) and surfaces using a novel dry gas release intervention. The efficacy of CD slow release 30-day sachets was tested on N95 face masks inoculated with human coronavirus OC43 in suspension. One sachet was placed with an inoculated mask in plastic resealable bags. Three trials were completed using the original sachet where a mask and sachet were placed into a plastic bag for 13 hours per sachet age of 1 day, 14 days, and 30 days. The amount of CD generated during a 13-hour treatment period was 0.30 mg. The nominal concentration of CD was estimated to be 317 mg/m3. All three tests demonstrated at least a 99.91% reduction of viral loading in the mask versus a non-treated control. Efficacy of CD dry gas fast releasing pods (Ultrashok) for fumigation was also tested in a 1344 ft3 closed room. Two pods were placed in the space and CD surface virucidal efficacy was tested in three locations of the room after 1 hour and 2 hours of dwell time. The estimated nominal peak concentration was 15 ppmv in the room. The one-hour exposure saw a >99.91% OC43 reduction on surfaces and the two-hour exposure resulted in a >99.997% OC43 reduction on surfaces versus a non-treated control. These results indicate dry CD is highly effective against human coronavirus. CD was 99.91% effective for eliminating human coronavirus OC43 in both sachet and capsule fumigant form using both fast and slow release mechanisms. Rapid fumigant application is suitable for contaminated rooms, ambulances, emergency vehicles, and many types of PPE, most particularly porous PPE materials. The gaseous state of CD allows for rapid diffusion and transfer of the virucidal stable free radical to all surfaces of PPE and indoor areas that would favor virus survival. Additionally, this work suggests CD can be effective at levels with significant margins of safety (little to no exposure and rapid degradation of residuals) providing minimal public health risks associated with the use of CD.","PeriodicalId":71955,"journal":{"name":"职业病与环境医学(英文)","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44151577","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Diagnosis of AA continues to be a challenge, especially in the youngest children, who often present with abdominal pain accompanied by nonspecific signs. As epidemiological data on the relationship between acute appendicitis and environmental factors are relatively few and the issue is still controversial, we conducted this study which compared two groups of patients with complicated and noncomplicated appendicitis in a sample of patients admitted to a MNCMCH. The aim of this study was to determine the risk factors for complications in acute appendicitis in the paediatric population. Methods: Our study was performed on 1003 children admitted for suspected acute appendicitis and underwent appendectomy at the MNCMCH, Ulaanbaatar Mongolia, between January 2019 and December 2019. The diagnosis was based on the results of pathological examination. The two groups of complicated (gangrenous and perforated) and noncomplicated (catarrhal and phlegmonous) acute appendicitis were compared. Results: 1003 pediatric patients (≤18 years old) were suspected of having acute appendicitis and subsequently underwent surgery. From a total of 967 patients, 56% (n = 542) were male, 44% (n = 425) were female (gender ratio was 1.3:1). The histological examination noted that 33.1% were uncomplicated, 66.9% were complicated. While the incidence of acute appendicitis was higher during winter, the highest incidence of complicated appendicitis was observed equally in winter and autumn without significant association (p = 0.541). The months of December and March were marked by the highest incidence of AA. The highest incidence of complicated appendicitis was observed during the month of December (45%) with statistically significant difference (p < 0.001). Our study of the incidence of family history, allergy and family members was noted in complicated and noncomplicated group with statistically significant difference (p < 0.001). Conclusions: Pediatric acute appendicitis incidence is increased in winter months in Mongolia. Preventive measures to decrease morbidity and mortality associated with this disease can be taken during the winter seasons from December to March. However, further large-scale studies are needed to support this conclusion.","PeriodicalId":71955,"journal":{"name":"职业病与环境医学(英文)","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45654632","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of this paper is to identify and quantify the variables included in the Protocol for the Assessment of Vulnerability to COVID-19 in such a way that the result can be quantified and allows for a predictive effect on the degree of vulnerability. Methodology: The starting point is the design of a protocol proposal that includes 29 variables. Data is collected from a sample of 420 workers, quantifying the results according to each variable, the overall scores for each group of aspects assessed and, finally, the total score that estimates the degree of vulnerability according to established ranges. Results: Variables that have the highest coefficient and, therefore, the greatest weight in the probability of reaching a group of high or medium vulnerability are cardiovascular disease, cancer, and coagulation alteration. The weight of the labour aspects due to inadequate working conditions stands out. Conclusions: The results obtained with this protocol allow us to make a quantified assessment of labour vulnerability to COVID-19 by integrating individual variables of the worker, his working conditions and the preventive actions of his company against COVID-19, and can be useful as an Occupational Vulnerability Index (OVI).","PeriodicalId":71955,"journal":{"name":"职业病与环境医学(英文)","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47286062","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This research aims to characterize respiratory protection practices among Florida firefighters. This information will allow better understanding of factors that are associated with non-compliance with respiratory protection guidelines. A survey questionnaire was used to characterize Florida fire departments in this cross-sectional study. Four hundred and seventy-seven surveys were administered to Florida firefighters both in person and electronically to collect information regarding firefighter knowledge and participation in their respective respiratory protection programs during the past twelve months. Survey questions were developed from the model set by the National Fire Protection Association (NFPA) which provides standards and regulations regarding firefighter protections. Summary statistics regarding firefighter department size, coverage area, and firefighter employment type were produced. Multinomial logistic regression analysis was performed to evaluate factors that impact respiratory protection programs. The 477 respondents were 91% male with a mean age of 39 years old (range 21 - 65 years). The majority of respondents, 76%, were non-smokers, 21% former smokers, and 3% current smokers. In regard to ethnicity, respondents were 77% Caucasian, 13% Hispanic, 3% African American, and 4% other. Most respondents were career firefighters, 97%, with less than ten years of experience, 44%, working in a fire department with at least 21 firefighters, 98%. Most respondents, 80%, had a written respiratory program in place. The most cited reason for not having implemented a written respiratory protection program was lack of knowledge related to the program. Multinomial logistic regression analysis of departments with response areas of at least 250,000 square miles produced a statistically significant 0.444 (0.219 - 0.901 CI) odds ratio for having a written respiratory program as compared to those with a less than 10,000 square miles response area. Additional resources need to be given to Florida fire departments to ensure that all firefighters receive adequate respiratory protection in accordance with NFPA guidelines. There is an association between fire departments with large response areas and non-compliance with respiratory protection guidelines in regard to: having a written respiratory program, the frequency of respiratory fit testing, and the frequency of medical fitness testing. This suggests that rural fire departments need additional resources to ensure firefighters are adequately protected. Additional research should focus on why these differences exist in the rural fire departments. Respondents stating a lack of knowledge or no requirement for a written respiratory program suggest that future efforts should focus on respiratory protection education and tr","PeriodicalId":71955,"journal":{"name":"职业病与环境医学(英文)","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44087467","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a result, there are gaps in our understanding of the effectiveness of a standard work practice control (handwashing) in the prevention and control of elevated blood lead levels (BLLs) in the workplace. The primary objective of this study was to assess if a National Institute for Occupational Safety and Health (NIOSH) formulation intended to remove lead from skin (Hygenall© LeadoffTM Foaming Soap) is more effective than a commonly used soap in the industrial painting industry (Zep Cherry Bomb Soap) in reducing the concentration of lead on workers’ hands after exposure. A secondary aim was to assess if using LeadoffTM Foaming Soap during handwashing reduces worker uptake of lead on bridge painting projects. We evaluated hand wipe, air sample and blood lead level data collected by two industrial bridge painting contractors. Airborne exposures ranged from 350 μg/m3 to 19,700 μg/m3. The geometric mean lead concentration remaining on workers’ hands after using Zep Cherry Bomb Soap was 77 μg per hand wipe compared with 61 μg per hand wipe after use of LeadoffTM Foaming Soap for all work classifications. The geometric lead concentration on workers’ hands decreased by 16 μg/hand wipe for all work classifications combined after using LeadoffTM Foaming Soap—a decrease of 21%. The use of Hygenall LeadoffTM Foaming Soap reduced the maximum lead concentration on workers’ hands by 85%. The geometric mean BLL for all work classifications was 12.1 μg/dl before the use of LeadoffTM. After two months of airborne exposure and use of LeadoffTM Foaming Soap at breaks and at the end of the workday, the geometric mean BLL for all work classifications increased to 18.1 μg/dl. Worker BLLs increased despite the reduction in the concentration of lead measured on workers’ hands—most likely a result of ineffective inhalation exposure controls.
