Occupational low back pain (LBP) remains a leading safety and health challenge. This cross-sectional investigation measured the prevalence of LBP in residential carpenters and investigated ergonomic risk factors. Ninety-four carpenters were investigated for LBP presence and associated risk factors. Ten representative job-tasks were evaluated using the Ovako Working Posture Analysis System (OWAS) and ErgoMaster™ 2D software to measure elements of posture, stress, and risk. Job-tasks were found to differ significantly for total lumbar compression and shear at peak loading (p < .001), ranging from 2 956 to 8 606 N and 802 to 1 974 N respectively. OWAS indicated that slight risk for injury was found in 10 job-tasks while distinct risk was found in 7 of the 10 job-tasks. Seven of the 10 job-tasks exceeded the National Institute for Occupational Safety and Health (NIOSH) action limit of 3 400 N for low back loading. The point prevalence for LBP was 14% while the annual prevalence was 38%.

EN
The aim of the study is to investigate the most frequent cause of superficial mycoses in patients from the territory of city Niš Southeast Serbia in the period from 1998 to 2010. A total of 3223 samples from 2887 patients with suspected dermatomycoses were examined. Superficial mycoses were diagnosed using standard microbiology techniques (conventional microscopy and cultivation). Dermatophytes were determined on the basis of their macroscopic and microscopic morphological and morphometric characteristics. Morphometric characteristics were obtained by Laboratory Universal Computer Image Analysis system (Lucia M, 1996). Species of genus Candida were identified using the test of production of germ tube in sera, by growth on comertial chromatogen medium (Chromotogenic Candida, Liofichem/Bacteriology products, Italy) and by using Auxacolor TMBioRad, France. The results were elaborated with the statistical method of descriptive and quantitative analysis (SPSS 14.0 for Windows 2003). The prevalence of superficial mycoses was 25,1%. Dermatophytes were identified in 67.6% of all positive cultures. Microsporum canis was the most prevalent (50.3%) dermatophyte isolated, followed by Trichophyton metagrophytes var. mentagrophytes (35.4%). Yeast genus Candida has become a more frequent cause of superficial fungal infection since 2001. and C. albicans was the dominant yeast (61.1%).

EN
The goal of the study was to assess the prevalence of stress urinary incontinence in a group of elite female endurance athletes, as professional sport is one of the risk factors for stress urinary incontinence. SUI rates in the groups of female cross-country skiers and runners were compared to determine whether the training weather conditions like temperature and humidity influenced the prevalence of urinary incontinence. An anonymous questionnaire was distributed among 112 elite female athletes ie., 57 cross-country skiers and 55 runners. We used a short form of the Urogenital Distress Inventory (UDI-6) to assess the presence of SUI symptoms and the level of urogenital distress. Only women who had been practicing sport professionally for at least 3 years, on an international and national level, were included in the research. The study group consisted of 76% nulliparous and 24% parous women. 45.54% of all participants reported leakage of urine associated with sneezing or coughing which indicates stress urinary incontinence. 29.46% were not bothered by the urogenital distress symptoms. 42.86% of the participants were slightly bothered by the symptoms, 18.75% were moderately bothered, 8.04% were significantly bothered and 0.89% were heavily bothered. The absence of statistically significant differences between both groups seems to indicate that training weather conditions did not influence the prevalence of SUI in elite female endurance athletes.

The study examined the body weight and parasites prevalence of African giant rat (Cricetomys gambianus Waterhouse, 1840) in rural setting of Gboko Local Government of Benue State. A total of 15 rats (10 males and 5 females) were collected from the wild and subjected to parasites isolation and body weight measurement at the Department of Fisheries and Aquaculture laboratory, Joseph Sarwuan Tarka University, Makurdi. Data was analyzed using descriptive statistics and student T-test. Results revealed a significantly higher (1.99kg) mean body weight in males rats compared to females (1.2 kg) (p<0.05). Parasite prevalence revealed 3 groups of Endo parasites (Roundworm, Flagellates and Tapeworm) and an Ecto parasite (flea) in the rats. However, there was no significant difference between the male and female rats in terms of the Endo/Ecto parasites count and load (p> 0.05). More so, body weight, endo and ecto parasites count and load were highly correlated with sex in the animals. For healthier consumption and domestication, adequate attention should be given towards the control of both endo and ecto parasite of captive reared African giant rat.

Objectives. The purpose of the study was to translate the revised version of the Negative Acts Questionnaire (NAQ-R) into the Czech language with a back translation procedure, and to test the reliability, validity, and factor structure of the scale. Sample and setting. The sample consisted of 7103 employees of public, private, and nonprofit organizations from all the regions of the Czech Republic (26.26% men, and 73.74% women, M = 42, SD = 11.03). The variables were assessed by Negative Acts Questionnaire - Revised (NAQ-R), Questionnaire detecting the structure and the dynamics of subjective states (SUPSO) as well as Anamnestic Questionnaire. Statistical analysis. Using softwares R (package „polycor“), SPSS Amos 24 and Statistica 12, calculation of descriptive statistics, Cronbach’s α, Revelle’s β, Pearson and polychoric correlation coefficients, exploratory and confirmatory factor analysis were performed. Results. The confirmatory factor analysis confirmed the three-factor structure of the Czech version of the NAQ-R. The total Cronbach’s alpha (0,94) for the 22 behavioural items indicated a high reliability and satisfactory internal consistency of the Czech version of the NAQ-R. The significant correlations between the three factors of the NAQ-R and the seven scales of the SUPSO diagnostic questionnaire suggest a high external validity of the Czech version of the NAQ-R. Study limitations. Although the negative acts questionnaire (NAQ-R) has satisfactory psychometric properties, the method of questioning fails to discern the motivational, emotional and other mental processes including the complex dynamics of formal and informal relationships among employees affected by bullying. The authors recommend the use of mixed approach research design in future studies of workplace bullying. Among the limits of this research are some specifics in the electronic data collection, since only 19.9% of the respondents (9143) fullfiled the complete questionnaire.

Cíle. Cílem studie byl překlad revidované verze Dotazníku negativních aktů (NAQ-R) do českého jazyka a ověření reliability, validity a faktorové struktury škály. Soubor a procedura. Výzkumný vzorek tvořilo 7103 zaměstnanců z veřejného, soukromého a neziskového sektoru ze všech krajů České republiky (26,26 % mužů a 73,74 % žen, M = 42, SD = 11,03). Proměnné byly zaznamenány pomocí NAQ-R, dotazníku zachycujícího psychickou strukturu a dynamiku (SUPSO) a anamnestickým dotazníkem. Statistická analýza. S využitím programů R (package „polycor“), SPSS Amos 24 a Statistica 12 byly provedeny výpočty deskriptivní statistiky, Cronbachova α, Revelleho β, Pearsonových a polychorických korelačních koeficientů, explorační a konfirmační faktorové analýzy. Výsledky. Konfirmační faktorová analýza potvrdila třífaktorovou strukturu českého překladu NAQ-R. Celkové Cronbachovo α pro 22 behaviorálních položek bylo 0,94, což vypovídá o vysoké reliabilitě české verze NAQ-R. Signifikantní korelace mezi třemi faktory NAQ-R a sedmi škálami SUPSO poukázaly na vysokou externí validitu NAQ-R. Omezení studie. Přestože český překlad NAQ-R má uspokojivé psychometrické vlastnosti, není tento dotazník schopen zachytit motivační, emoční a další psychické procesy včetně komplexní dynamiky formálních a neformálních vztahů mezi účastníky šikany na pracovišti. Autoři doporučují v budoucích studiích mobbingu využít kombinaci smíšeného metodologického přístupu. Mezi limity tohoto výzkumu patří jistá omezení elektronického sběru dat vzhledem tomu, že ze 45897 oslovených osob pouze pětina (9143) dokončila vyplňování dotazníku.

EN
When conducting prevalence surveys pressure ulcers were found in participants clearly identified not to be at risk. This article determines and analyses persons in German hospitals and nursing homes who suffer from pressure ulcers but are not at risk. In the years 2002, 2003 and 2004 there were 7,097 nursing home residents and 23,966 hospital patients examined in annual pressure ulcer prevalence surveys. A risk assessment according to the Braden Scale was performed for each participant on the day of the survey. “Not at risk” participants were defined by Braden score cut-off > 20 points. There were 440 of 3,012 (14.6%) persons with pressure ulcer who were considered not to be at risk. In hospitals, 16.1% of all patients with pressure ulcers were not at risk, in nursing homes it was 8.2%. A high variance between medical specialties and individual institutions was found in the number of those not at risk but with pressure ulcer. In the group not at risk, persons with and without a pressure ulcer differed regarding activity and friction and shear in nursing homes. In hospitals those persons differed regarding age and all single items of the Braden scale apart from sensory perception. Pressure ulcers that are more severe, located at the hip or lower back or the origin of which is unknown are more likely to be considered to be at risk by the Braden risk assessment tool. The results may indicate insufficient abilities of the Braden scale for certain kind of pressure ulcer wounds.

Objectives This study has investigated the prevalence of work-related musculoskeletal disorders (WMSDs), the most commonly affected body parts, the risk factors of WMSDs and the coping strategies adopted by hairdressers. Material and Methods The study design was a cross-sectional descriptive survey design. Two hundred and ninety-nine hairdressers (242 females and 57 males) from salons in Surulere and Mushin Local Government Areas of Lagos State completed a 27-item questionnaire. They were selected using a non-probability consecutive sampling technique. The inferential analysis was conducted using the Chi² test. The level of significance stood at p < 0.05. Results The 12-month prevalence of musculoskeletal disorders stood at 75.6%. Two hundred and twenty-one (91.3%) participants reported gradual onset of musculoskeletal disorders. One hundred and sixteen (47.9%) participants had the onset of the WMSDs at the age range of 26–35 years. The most commonly affected body parts included the low back (76.3%), shoulder (62.5%) and neck (46.3%). Some of the major job risk factors of the WMSDs that were identified included: working in the same position for long periods and attending to a large number of customers in 1 day. Taking sufficient rest breaks by participants was one of the coping strategies adopted by the participants. The mean number of years of working experience was 7.85±0.4 years. One hundred and twenty-four (41.5%) participants had worked for 1–5 years. The Chi² analysis showed that the prevalence of musculoskeletal disorders were significantly associated with the age of a participant (Chi² = 78.78, p = 0.001), years of working experience (Chi² = 78.03, p = 0.001) and hours spent working in a standing position (Chi² = 8.77, p = 0.01), respectively. Conclusions The age of hairdressers, their years of working and the long hours they spent working in a standing position may be significant factors that contribute to the high prevalence of the WMSDs among them. The most commonly affected body parts included the low back, shoulders and neck.

Self-report measures of musculoskeletal discomfort are a widely used and generally accepted risk factor for musculoskeletal disorders in epidemiologic research. The aim of this study was to investigate the prevalence of musculoskeletal symptoms in packing workers. A cross-sectional study of 75 workers was carried out using a modified Nordic questionnaire. Prevalence was determined with the percentage of positive responses to questions on musculoskeletal symptoms. Odds ratios and 95% confidence intervals were the measures of association between prevalent musculoskeletal symptoms and demographic factors; they were determined with logistic regression. Most musculoskeletal symptoms in workers were from the low back (44.0%), shoulders (33.3%) and neck (32.0%). Years worked were strongly significantly associated with musculoskeletal symptoms and pain in the neck, shoulders and wrists/hands, P < .001–.050. Hazards related to repetitive movements and discomfort postures could be reduced with stretching exercises, rotation schedules and through new engineering solutions.

The reported prevalence of periampullary duodenal diverticula varies between 9 and 32.8%. The aim of the study was to evaluate the prevalence of periampullary diverticula in the studied population and establish whether their presence influence the risk of choledocholithiasis and the risk of Endoscopic Retrograde Cholangio Pancreatography (ERCP) related complications. Material and methods. The study group of 3788 patients who underwent ERCP between 1996 and 2016at the 2nd Department of General Surgery Jagiellonian University Medical College in Kraków were analyzed. The group comprised of 2464 women (mean age 61.7 years) and 1324 men (mean age 61.8 years). The patients were divided into two groups. Group A included patients in whom there were no periampullary diverticula detected. Group B included patients in whom the opening of the bile duct was in the vicinity of a duodenal diverticulum. Results. There were 3332 patients included in group A (2154 women and 1178 men) and 456 patients in group B (310 women and 146 men). The prevalence of periampullary duodenal diverticula in the analyzed group was 12.8%. The presence of stones or biliary sludge was diagnosed in 1542 patients (47.6%) in group A and 290 patients (68.1%) in group B. Recurrence of choledocholithiasis occurred in 4.5% of patients (70/1542) in group A and 10.3% of patients (30/290) in group B. Complications occurred in a total of 76 patients in group A (2.3%) and 22 patients in group B (4.8%). Conclusions. The presence of choledocholithiasis and the risk of ERCP related complications are significantly higher in the group with duodenal diverticula.

A study was carried out to determine the prevalence of parasitic infections among the nomadic Fulanis of south-eastern Nigeria between September 2003-March 2004. Urine, stool and blood specimens were collected from each of 231 subjects. Of these, 98 (42.4%) were infected with one or more of 14 parasitic species, of which Plasmodium malariae had the highest prevalence (15.3%). Others included 6 intestinal helminth parasites: Ascaris lumbricoides, hookworm, Strongyloides stercoralis, Schistosoma mansoni, Enterobius vermicularis, Trichocephalus trichiurus, 2 protozoan parasites: Entamoeba histolytica and E. coli, 4 blood parasites: Mansonella perstans, Loa loa, Trypanosoma sp, Plasmodium falciparum, as well as Schistosoma haematobium recovered in the urine. Prevalence of these parasitic infections varied significantly among bush encampments, sexes, and age groups. They had evidence of onchocerciasis. Their occupational imperatives, beliefs and general life style are contributing factors to the prevalence of parasitic infections among the nomadic Fulanis of south eastern Nigeria. Aspects of prevalence and control of parasitic infections are discussed.
