Health damage caused by occupational exposure to formaldehyde in personnel working in hospital centers.
(Universidad Privada Norbert Wiener, 2018-03-25) Centeno Ochoa, Fanny Edith; Huamán Cristóbal, Melva; Matta Solis, Hernan Hugo
The objective is to systematize the evidence on health damages caused by occupational exposure to formaldehyde in personnel working in healthcare centers. Materials and Methods: A systematic review of 10 articles. Various scientific articles were found using databases such as Cochrane Review, Lilacs, Pubmed, Epistemonikos, Intramed, Scielo. Of the 10 pieces of evidence found, 10% (1/10) correspond to Systematic Review and Meta-analysis, 10% (1/10) to Meta-analysis, 10% (1/10) to Systematic Review, 30% (3/10) to case-control studies, 10% (1/10) to quasi-experimental studies, and 30% (3/10) to cross-sectional design. 20% of the evidence comes from the United States, and 10% from India, Spain, Iran, Portugal, Egypt, Brazil, Norway, and Ethiopia, respectively. Results: 60% (n=6/10) of the studies show that occupational exposure to formaldehyde in healthcare personnel causes damage to the upper respiratory tract, eye irritation, toxic effects on the nervous system, and cancer development; 40% (n=4/10) of the reviewed studies found insufficient scientific evidence to demonstrate a significant association between exposure to formaldehyde and respiratory, nervous, and cancer diseases in exposed individuals. Conclusion: The academic work, consisting of a systematic review, evidences that the majority of the studies included show that occupational exposure to formaldehyde in healthcare personnel causes damage to the upper respiratory tract.

Occupational exposure to asbestos and the risk of lung cancer in workers
(Universidad Privada Norbert Wiener, 2018-01-27) Sotelo Rodas, Liliana Mauri; Villavicencio Laureano, Judith Rocio; Pretell Aguilar, Rosa Maria
Objective: To analyze and systematize the evidence on occupational asbestos exposure and the risk of lung cancer in workers. Materials and Methods: This is a qualitative study with systematic reviews, meta-analysis, and cohort designs, using databases such as PubMed NCBI, Redalyc, and Cochrane, with articles not older than 10 years and in English. Results: A total of 30 articles were analyzed, with a sample of 10 articles. Of these, 30% (3) were systematic reviews, 10% (1) were meta-analyses, and 60% (6) were cohort studies. The systematic reviews were international, with 40% (4) from the United States, 20% (2) from the Netherlands, 20% (2) from China, 10% (1) from Italy, and 10% (1) from Denmark. Conclusions: According to the 10 reviewed articles, 100% concluded that occupational exposure to asbestos increases the risk of lung cancer in workers. The relative risk increases by 1% to 4% per fiber-year (FY) / ml of exposure, and even at low levels of exposure, the relative risk of lung cancer is elevated. Other cancers by gender also increased: men showed a higher risk of lung and laryngeal cancers, while women showed a higher risk of ovarian cancer. Significantly increased lung cancer rates were associated with cumulative fiber exposure.

Occupational exposure to asbestos and the risk of lung cancer in workers.
(Universidad Privada Norbert Wiener, 2018-01-27) Villavicencio Laureano, Judith Rocío; Sotelo Rodas, Liliana Mauri; Pretell Aguilar, Rosa Maria
Materials and Methods: The study type of this work is qualitative, with a design of systematic reviews, meta-analyses, and cohort studies. The databases used were Pubmed NCBI, Redalyc, and Cochrane, with articles no older than 10 years and in English. Results: In the present study, 30 research articles were analyzed, and the sample consisted of 10 articles, of which 30% (3) were systematic reviews, 10% (1) were meta-analyses, and 60% (6) were cohort studies. The systematic reviews are international in nature, with 40% (4) from the United States, 20% (2) from the Netherlands, 20% (2) from China, 10% (1) from Italy, and 10% (1) from Denmark. Conclusions: According to the 10 articles reviewed, 100% concluded that occupational exposure to asbestos increases the risk of lung cancer in workers, with a relative risk increase between 1% and 4% per fiber-year (FY) / ml of exposure. Even at low levels of asbestos exposure, there is an increased relative risk of lung cancer. There is an increased risk of other cancers by gender, with men presenting lung and laryngeal cancers and women presenting ovarian cancer. The rates of lung cancer significantly increased with cumulative fiber exposure.

Occupational exposure to noise of workers in the welding workshop of an open pit mine in northern Peru, 2020
(Universidad Privada Norbert Wiener, 2020-10-25) Gamarra Castro, Lida Carmen; Pretell Aguliar, Rosa María
The occupational exposure to noise of workers in a welding workshop at an open-pit mine in northern Peru is evaluated based on two relevant factors: the location within the welding workshop and the specific activity performed by the workers. Ignorance of its influence could lead to an underestimation of the workers' noise exposure risk and, consequently, the effectiveness of the hearing conservation program. The objective of this research is to determine the occupational exposure to noise of the workers in the welding workshop. The approach is quantitative, with a cross-sectional, descriptive, and prospective design, of a longitudinal nature. The population will consist of 120 workers, and the stratified sample will include 70 workers, with 35 from the day shift and 35 from the night shift.

Occupational exposure to pesticides and the risk of neurodegenerative diseases in workers
(Universidad Privada Norbert Wiener, 2019-04-07) Zapata Quispe, Raquel; Miguel Zacarias, Yolanda Maria; Pretell Aguilar, Rosa María
10 articles of high scientific value were selected about occupational exposure to pesticides and the risk of neurodegenerative diseases in workers. We found that 10% of the articles are from Belgium, 30% from Sweden, 10% from China, 10 % from Korea and 10% from France and 30% from the USA. In turn, 50% are systematic reviews and meta-analyses, 10% are systematic reviews, 20% are cohort studies and 20% are case controls. 100% of articles demonstrate that occupational exposure to pesticides generates a risk of neurodegenerative diseases in workers. Of which 50% demonstrate that they generate a risk of Parkinson's, 20% generate a risk of amyotrophic lateral sclerosis (ALS) and 20% demonstrate that they generate a risk of Alzheimer's in workers and the remaining 10% affirm that they generate a risk of the three diseases. neurological. It is concluded that occupational exposure to pesticides does generate a risk of neurodegenerative diseases in workers. The risk of neurodegenerative diseases increases considerably when the worker remains in direct contact and maintains continuous exposure to pesticides.

Occupational risks presented by the staff of the sterilization center of the national hospital dos de Mayo
(Universidad Privada Norbert Wiener, 2021-11-14) Vásquez Rojas, Audila; Suarez Valderrama, Yurik Anatoli
The sterilization center is an exclusive area where it is responsible for providing all services with the sterile medical devices necessary for the care of the user, the performance of the activities the worker may suffer some injury or damage to the detriment of their health, this occupational exposure requires being determined in order to take the necessary prevention and control measures. Objective: to determine the occupational risks presented by the staff of the Sterilization Center of the Dos de Mayo National Hospital between the months of October to December 2021Materials and methods: this research will have a quantitative approach, with a descriptive and cross-sectional methodological design. The population will be made up of 47 workers, both women and men, who work at the Sterilization Center. The data collection technique will be the survey through a questionnaire prepared by the author, the instrument was subjected to expert judgment with validity and reliability tests with an accepted level, it was worked with the Kuder-Richarson dichotomous statistical analysis (1: yes it is favorable and 0: it is not favorable).
