Introduction The study aimed at measuring exhaled breath malondialdehyde (EBC-MDA) in workers exposed to dust containing silica and at its comparison with the non-exposed control group. Material and methods The cross sectional, case-control study (N = 50) was performed in a tile and ceramics production factory in Yazd, Iran. EBC-MDA was quantified in exhaled breath of the participants by a lab made breath sampler. Exposure intensity was measured according to the NIOSH 0600 method in selected homogeneous exposure groups. Additionally, spirometry test was conducted to investigate a correlation between EBC-MDA and spirometric findings in the exposed workers. Results There was no difference in the observed exposure intensities of silica containing dust in different units. However, “coating preparation” was the unit with the highest concentration of dust. Although, the level of EBC-MDA in the cases was slightly higher than in the controls, the difference was not statistically significant (U = 252, p = 0.464). A significant and positive correlation was found between dust exposure intensity in working units and the measured EBC-MDA of workers (r = 0.467, N = 25, p = 0.027). There were also no statistically significant differences among job categories in the exposed group for the values of FEV1% (F(3, 44) = 0.656, p = 0.584), FVC% (F(3, 44) = 1.417, p = 0.172), and FEV1/FVC% (F(3, 44) = 1.929, p = 0.139). Conclusions The results showed a significant correlation between respirable dust exposure intensity and the level of EBC-MDA of the exposed subjects. However, our results did not show a significant correlation between lung function decreases and EBC-MDA.

Objective: The role of occupational hazards in occupational injury may be mediated by individual factors across various age groups. This study assessed the role of occupational hazards as well as contribution of individual factors to injuries among Indian and French coalminers. Material and Methods: We conducted a case-control study on 245 injured workers and on 330 controls without any injuries from Indian coal mines using face-to-face interviews, and a retrospective study on 516 French coalminers using a self-administered questionnaire including potential occupational and personal factors. Data were analyzed using logistic models. Results: The annual rate of injuries was 5.5% for Indian coalminers and 14.9% for the French ones. Logistic model including all occupational factors showed that major injury causes were: hand-tools, material handling, machines, and environment/work-geological/strata conditions among Indian miners (adjusted oddsratios 2.01 to 3.30) and biomechanical exposure score among French miners (adjusted odds-ratio 3.01 for score the 1-4, 3.47 for the score 5-7, and 7.26 for score ≥ 8, vs. score 0). Personal factors among Indian and French coalminers reduced/exacerbated the roles of various occupational hazards to a different extent depending on workers' age. Conclusion: We conclude that injury roles of occupational hazards were reduced or exacerbated by personal factors depending on workers' age in both populations. This knowledge is useful when designing prevention which should definitely consider workers' age.

Objective: Sharp injuries constitute important occupational exposure in hospital environment, and perhaps the newly graduated medical and dental students, known as House Officers, in the first twelve months of their practice, are the most vulnerable of all health workers. This study was designed to examine the nature and prevalence of occupational injuries among medical and dental house officers and factors associated with reporting these injuries. Materials and Methods: A self-administered questionnaire was used to obtain information on demography, types of exposure, and barriers to official reporting of occupational injuries. One hundred and forty-four medical and dental house officers in 3 government owned hospitals in Edo State, Nigeria participated in the study, between April and May, 2010. Descriptive and multivariable analyses were performed. Results: The overall response rate was 96%. Out of all participants, 69.4% were male; 82.6% were medical house officers. Prevalence of percutaneous injury was 56.9%; where needlestick injury constituted one-third of all injuries. Mean frequency of injury was 1.86±2.24, with medicals having more injuries (p = 0.043). The ward was the most common location for the injury and 14.8% of exposures occurred as a result of lapse in concentration. At least 77.0% did not formally report their injury and perceived low injury risk was the most common reason given (51.67%). Conclusion: This study shows that a substantial number of House Officers are exposed to occupational injuries and that the majority of them does not formally report these. Safer work environment may be achieved by implementing adequate educational programs tailored specifically to house officers, and policies encouraging exposure reporting should be developed.

Paramedics constitute a group of professionals who are constantly exposed to potentially infectious biological material through frequent and close contact with patients, possibly resulting in occupationally acquired infections. The paper’s objective has been to assess the occupational risk regarding blood-borne infections and identify preventive measures used among paramedics worldwide, on the basis of the related literature review. The literature search, covering the period 1987–2017, was performed using PubMed, Elsevier, Springer and Google Scholar databases. A comparative analysis of blood exposure was conducted and the report of such events and the use of personal protective equipment among paramedics in Poland and other countries worldwide was developed. The data on occupational blood exposures among paramedics is sparse. The resulting comparisons obtained in various scientific studies are difficult due to diverse data collection methods, influencing the resulting consistency. Additionally, there were some methodological errors found in previously published studies, such as selection bias. The percentage rate of paramedics exposed to blood in the last 12 months varies from 22% in the USA to 63% in Thailand; in Poland that rate fluctuates widely, ranging between 14–78%. Paramedics are frequently exposed to blood while performing their duties, but almost 50% of paramedics do not report any exposure which is mitigated by the systematic use of personal protective equipment: gloves are regularly used by 53–98% of paramedics, masks and goggles are worn by 33–62% of them. This fact puts the paramedics group at risk of blood-borne infections. Therefore, there is an urgent need to conduct further, methodologically correct, multi-center studies to accurately assess occupational blood exposure in paramedics. Med Pr 2018;69(6):685–694

Ratownicy medyczni poprzez częste i bezpośrednie kontakty z pacjentami narażeni są na ekspozycje na potencjalnie zakaźny materiał biologiczny, co może skutkować zakażeniami zawodowymi. Celem pracy była ocena ryzyka zawodowych zakażeń krwiopochodnych i stosowanych metod prewencji w tej grupie profesjonalnej na podstawie przeglądu piśmiennictwa. Materiał badawczy stanowiły dane z artykułów zgromadzonych w bazach PubMed, Elsevier, Springer i Google Scholar w latach 1987–2017. Dokonano analizy porównawczej danych o ekspozycji zawodowej na krew wśród ratowników medycznych, zgłaszaniu takich zdarzeń i stosowaniu środków ochrony osobistej w poszczególnych państwach w porównaniu z danymi z Polski. Przeprowadzono dotychczas niewiele badań epidemiologicznych związanych z narażeniem zawodowym na krew wśród ratowników medycznych. Porównanie wniosków uzyskanych przez poszczególne zespoły badawcze jest trudne z uwagi na różne sposoby gromadzenia danych. Wpływa to na znaczne zróżnicowanie obserwowanych wyników. Ponadto część publikacji wykazuje błędy metodologiczne, najczęściej stronniczość selekcji. Na świecie odsetek ratowników, którzy ulegli ekspozycji w roku poprzedzającym badanie, waha się od 22% w USA do 63% w Tajlandii. W Polsce analogiczne odsetki oscylują w granicach 14–78%. Choć ta grupa profesjonalistów jest narażona na częsty kontakt z krwią, niemal połowa badanych nie zgłasza ekspozycji zawodowych. Informowanie o takich zdarzeniach jest rzadkie, podobnie jak systematyczne stosowanie środków ochrony osobistej – rękawice ochronne regularnie używa 53–98% badanych, maski i okulary ochronne – 33–62%. Zwiększa to ryzyko zakażenia patogenami krwiopochodnymi. Konieczne wydaje się zatem przeprowadzenie dalszych, poprawnych metodologicznie, wieloośrodkowych badań dokładnie oceniających ekspozycje zawodowe na krew wśród ratowników medycznych. Med.
