Opis:
The paper presents a general overview of risk factors in gynaecological oncology based on a review of recent literature, highlighting their role in preventive medicine. Since mid-twentieth century the role of risk factors is being increasingly appreciated, particularly those directly associated with the risk of developing certain diseases, including female genital malignancies. Several risk factors have been defined, e.g. genetic, biologic, socioeconomic, cultural, geographic, iatrogenic and environmental and their list is ever increasing. This has made possible the definition of high-risk groups of women, who require close medical monitoring in order to detect neoplastic disease at an earliest possible stage. Risk factors usually precede the process of carcinogenesis, although both may be synchronous. Risk factors have various prognostic values: one risk factor may be present in several different neoplasms and several different risk factors may be associated with a single tumour. A frequent phenomenon is oncological synergy. Most female genital neoplasms are multifactorial diseases.
Opierając się na przeglądzie piśmiennictwa ostatnich lat, przedstawiono ogólne wiadomości o czynnikach zagrożenia w ginekologii onkologicznej, podkreślając ich znaczącą rolę w medycynie zapobiegawczej. Począwszy od lat 50. XX w., przywiązywano dużą wagę do czynników ryzyka wskazujących na możliwość wystąpienia zagrożenia powstania choroby, w tym również nowotworów narządów płciowych u kobiet. Wykryto wiele czynników zagrożenia począwszy od genetycznych, poprzez biologiczne, socjoekonomiczne, kulturowe, geograficzne, jatrogenne, a skończuwszy na środowiskowych i lista ta jest ciągle uzupełniana. Dało to podstawy do wyodrębnienia spośród populacji kobiet grup podwyższonego ryzyka wymagających wzmożonej kontroli medycznej, co z kolei pozwalało na wykrycie choroby nowotworowej we wczesnym etapie jej rozwoju. Czynniki zagrożenia na ogół poprzedzają proces kancerogenezy, choć mogą też w nim uczestniczyć. Przedstawiają one różną wartość kliniczną: jeden czynnik zagrożenia może występować w wielu nowotworach, a wiele czynników - w jednej chorobie nowotworowej; często występuje synergizm onkologiczny. Większość nowotworów narządów płciowych to tzw. „choroby wieloczynnikowe”.

Opis:
The objectives of this study were to investigate the rate of cumulative trauma disorders (CTDs) in the upper body and to describe the associations of such disorders with ergonomic parameters in a group of data entry operators. A total of 173 data entry operators volunteered to take part in the study. Questionnaires were used to investigate their medical history. Diagnoses of CTDs were made with clinical tests. A visual posture analysis of the workers and an ergonomic analysis of workstations and workload were used to reveal risk factors. Neck and shoulder pain, extensor tendonitis of the wrists and De Quervain’s disease were common in the study population. An assessment of risk factors showed that leaning wrists on the keyboard, hard keystrokes, extreme wrist joint and thumb positions and working in poor ergonomic design were correlated to pain and development of CTDs.

Opis:
Badania monitorowe żywności wskazują, że człowiek jest stale narażony na pozostałości środków ochrony roślin (pestycydów) występujące w produktach spożywczych dostępnych w obrocie. Stąd szacowanie ryzyka dla konsumentów związanego ze spożywaniem produktów zawierających pozostałości substancji czynnych pestycydów, stanowi kluczowy etap zarówno procedury rejestracji pestycydów jak i urzędowej kontroli żywności. Jednak w wielu przypadkach dochodzi nie tylko do narażenia na pojedyncze substancje czynne, ale również na mieszaninę pozostałości pestycydów. Poziomy te są zwykle niskie, poniżej skutecznego działania i interakcje takie jak synergizm lub potencjacja nie są spodziewane. Jednocześnie dane literaturowe wskazują, że dla mieszanin charakteryzujących się wspólnym MOA (Mode of Action/Mechanism of Action) nawet przy uwzględnieniu niskich poziomów stężeń współwystępujących pozostałości pestycydów, istnieje duże prawdopodobieństwo wystąpienia działania addytywnego. Stąd szacowanie ryzyka zdrowotnego dla konsumentów narażonych na te mieszaniny (ryzyko skumulowane/łączne) staje się potrzebą chwili. Podjęte inicjatywy na poziomie UE, nad wypracowaniem właściwej metodologii dla szacowania skumulowanego/łącznego ryzyka umożliwiły znaczny postęp w tym zakresie. W artykule omówiono aspekty szacowania skumulowanego ryzyka dla konsumentów związanego z narażeniem na mieszaninę pozostałości pestycydów w żywności.
The results of food monitoring studies indicate that humans are constantly exposed to residues of plant protection products (pesticides) in marketed food products. Hence, assessment of the risk to consumers associated with the consumption of products containing residues of the active substances of pesticides is a key stage in both the registration of pesticides and official control of foodstuffs. However, there are frequent cases of exposure not only to individual active substances but also to mixtures of pesticide residues. These levels are usually low, below of effective action, and interaction such as synergism or potentiation is not expected to occur. At the same time, literature data indicate that for mixtures sharing a common MOA (Mode of Action/Mechanism of Action), the probability of additive effects is high, even after adjusting for the low levels of the mixed pesticide residues present. Accordingly, health risk assessment for consumers exposed to such mixtures (cumulative/ aggregate risk) has become an issue of topical importance. EU-level initiatives regarding the development of appropriate methodology for the estimation of cumulative/aggregate risk have brought about considerable progress in this area. The article discusses various aspects of estimation of cumulative risk for consumers associated with exposure to mixtures of pesticide residues in food.

Opis:
Research background: Numerous studies show that men's and women's situation on the labour market differs. Women's disadvantageous position on the labour market in Poland has been confirmed by statistical data (Kobiety..., 2016). The most common reasons for de-registration from the employment office are finding a job and deleting from the records due to an unjustified refusal to accept an offer by an unemployed person. Additionally, registered unemployed people can for example: retire, apply for invalidity pension, receive early retirement benefits or start full time studies. The above causes are regarded as competing risks of various kinds. Purpose of the article: The purpose of this article is to assess the effect of the unemployed individual's gender on the probability and intensity of de-registering from the labour office lists due to finding a job, de-registering or other causes. Methods: In the study the survival analysis methods were used. The assessment of the probability of de-registration due to a specific cause was made by means of the cumulative incidence function. The intensity of de-registration was tested with the Lunn-McNeil model. Differences in the effect of gender on the de-registration possibility were tested with the use of Gray's test. The study was based on individual data of people registered by the Labour Office in Szczecin. Findings & Value added: Among women, job-finding was the most common cause of de-registration, followed by the removal from the register. In the case of men the order was reversed, the most probable de-registration cause was the removal, followed by job-finding. The remaining causes were of marginal significance, both for men and women. Women took up a job more intensively than men and were less intensively removed from the register. The differences between males and females in the intensities of de-registering due to the remaining causes were not statistically relevant.

Opis:
The expected utility theory axioms have been studied experimentally. Three of the experiments are a repetition of an earlier test in slightly changed circumstances, while the other two are original. The participants were incentivised with rewards, which did not happen in the replicated tests. The results confirmed the degeneration of the expected utility theory as a scientific research program. The evidence that resulted from the tests supported the hypothesis on the cumulative prospect theory predicting facts not forecasted by the EUT.

Background Carpal tunnel syndrome (CTS) is a musculoskeletal condition that often impairs the fitness to work. Our aim is to retrospectively evaluate the association between physical exposures in meat processing industry in Northern Italy and the CTS, taking into account non-occupational factors. Material and Methods A cross-sectional study was performed to include 434 workers (236 males, 198 females, 37.0±10.6 years old, working age: 12.6±10.8 years) from meat processing industries. Signs and symptoms were collected at the compulsory occupational medical surveillance. Occupational risk factors were assessed through a questionnaire and direct assessment by investigators. Adjusted odds ratios (ORadj) for factors of interest were estimated through binary logistic regression. Results Diagnosis of the CTS was reported for 61 out of 434 subjects (14.1%) for an incidence of 11.3/1000 person- years. In general, signs and symptoms for the CTS were associated with the following demographic factors: smoking history (OR = 1.909, 95% confidence interval (CI): 1.107–3.293), previous traumas of the upper limb (OR = 3.533, 95% CI: 1.743–7.165), hypothyroidism status (OR = 7.897, 95% CI: 2.917–21.38) and, in the case of female participants only, previous pregnancies (OR = 2.807, 95% CI: 1.200–6.566) as well as a personal history of oral contraceptive therapy and/or steroidal replacement therapy (OR = 11.57, 95% CI: 4.689–28.56). The carpal tunnel syndrome cases were associated with the following occupational factors (> 4 h/day): forceful hand exertion (ORadj = 3.548, 95% CI: 1.379–9.131), repeated trauma of the hand (ORadj = 3.602, 95% CI: 1.248– 10.395), repeated movements of the wrist (ORadj = 2.561, 95% CI: 1.100–5.960). Conclusions Increasing levels of hand activity and force were associated with the increased CTS prevalence among participants. Recommendations have to be provided in order to reduce occupational exposure to these risk factors and improve medical surveillance. Med Pr 2017;68(2):199–209

Opis:
Objectives Carpal tunnel syndrome (CTS) is the most common nerve entrapment syndrome, which since the beginning of the seventies has been linked to the keyboard and visual display unit (VDU). The objective of this study was to investigate the prevalence and personal factors associated with CTS in female VDU workers in Italy. Material and Methods Participants in this study were female adult subjects, working ≥ 20 h/week (N = 631, mean age 38.14±7.81 years, mean working age 12.9±7.24 years). Signs and symptoms were collected during compulsory occupational medical surveillance. The binary logistic regression was used to estimate adjusted odds ratios for the factors of interest. Results Diagnosis of CTS was reported in 48 cases (7.6%, 11 of them or 1.7% after a surgical correction) for the incidence of 5.94/1000 person-years. In general, signs and symptoms of CTS were associated with the following demographic factors: previous trauma of upper limb (adjusted odds ratio (ORa) = 8.093, 95% confidence interval (CI): 2.347–27.904), history (> 5 years) of oral contraceptives therapy/hormone replacement therapy (ORa = 3.77, 95% CI: 1.701–8.354) and cervical spine signs/symptoms (ORa = 4.565, 95% CI: 2.281–9.136). Conclusions The prevalence of CTS was similar to the estimates for the general population of Italy. Among personal risk factors, hormone therapy, previous trauma of the upper limb and signs/symptoms of the cervical spine appeared to be associated with a higher risk of CTS syndrome. Eventually, the results reinforce interpretation of CTS in VDU workers as a work-related musculoskeletal disorder rather than a classical occupational disease.

Objectives To investigate the prevalence of work-related musculoskeletal disorders amongst dentists who work in public clinics in São Paulo, Brazil, to investigate their awareness of the presence of risk factors in the workplace, disability due to pain, and the influence of pain on this awareness and disability. Material and Methods A cross-sectional study was conducted among 204 dentists who work in public health clinics in the northwest of São Paulo, Brazil. The data was collected through interviews, using the Nordic Questionnaire and the Work-Related Activities that May Contribute to Job-Related Pain Questionnaire. In the case of workers who reported pain, the Pain Disability Questionnaire (PDQ) and the Numeric Pain Scale were also administered. Statistical analyses were performed using SPSS 21.0. Results Most dentists (81.4%) had musculoskeletal disorders, especially in the neck, shoulders and lower back. We found that the presence of symptoms in the neck (15.7%), shoulders (12.7%) and lower back (15.7%) were the major causes of absenteeism over the past 12 months. Occupational risk factors perceived as the most problematic ones were: bending or twisting the back in an awkward way, continuing to work when injured or hurt and working in the same position for long periods. Comparison between the symptomatic and asymptomatic dentists showed a statistically significant difference (p < 0.05) in the perception of occupational risk factors. The analysis of the intensity of pain and disability with PDQ in the symptomatic dentists showed an average pain intensity of 3.8. Mean scores of the PDQ total (11.46) and its dimensions – functional condition (7.1) and psychosocial condition (4.4) – suggest a moderate disability in the dental surgeons. There was a strong t correlation (r = 0.697) between pain intensity and the total score of disability caused by pain. Conclusions Pain and work-related musculoskeletal disorders interfere significantly with the dentists’ lives. In the case of dental surgeons there is a significant correlation between pain intensity and disability. Int J Occup Med Environ Health 2017;30(3):367–377
