Motion analysis in the field of dentistry: a kinematic comparison of dentists and orthodontists

2016

Objectives: To conduct a kinematic comparison of occupational posture in orthodontists and dentists in their workplace. Design: Observational study. Setting: Dentist surgeries and departments of orthodontics at university medical centres in Germany. Participants: A representative sample of 21 (10 female, 11 male) dentists (group G1) and 21 (13 female, 8 male) orthodontists (G2) with one male dropout in G2. Outcome measures: The CUELA (computer-assisted acquisition and long-term analysis of musculoskeletal loads) system was used to analyse occupational posture. Parallel to the recording through the CUELA system, a software-supported analysis of the activities performed (I: treatment; II: off…

Environmental exposure to dioxins and polychlorinated biphenyls reduce levels of gonadal hormones in newborns: Results from the Duisburg cohort study

2006

Abstract Background Endocrine dysfunction related to the hypothalamic–pituitary–thyroid (HPT) and/or the hypothalamic–pituitary–gonadal axis (HPG) is being discussed as underlying developmental adversity of polychlorinated dibenzo- p -dioxins and dibenzofurans (PCDD/Fs) and polychlorinated biphenyls (PCBs). This study was done to evaluate effects related to the HPG axis. Methods A birth-cohort study was initiated in the year 2000. Healthy mother–infant pairs were recruited in the industrialized city of Duisburg, Germany. Dioxins, dioxin-like PCBs and six indicator PCBs were measured in maternal blood during pregnancy and in maternal milk. Testosterone and estradiol levels were measured in m…

Speichel als Matrix für das Humanbiomonitoring in der Arbeits- und Umweltmedizin [Biomonitoring Methods in German Language, 2015]

2016

Saliva as a matrix for human biomonitoring in occupational and environmental medicine Purpose: Human biomonitoring (HBM) implies the assessment of internal exposure to hazardous substances by measuring the substances, their metabolites or reaction products, as well as effect parameters in human body fluids. Along with blood, plasma and urine, saliva is of increasing interest as an alternative matrix for HBM. Methods: This paper reviews studies that measure salivary background levels of hazardous substances, elevated levels after environmental or occupational exposure, as well as references which deal with physiological and toxicokinetic behaviour of saliva and salivary parameters, respectiv…

Retirement age and type as predictors of frailty : a retrospective cohort study of older businessmen

2020

ObjectivesTo study the association between retirement characteristics and frailty in a homogenous population of former business executives.DesignCross-sectional cohort study using data from the Helsinki Businessmen Study.SettingHelsinki, Finland.Participants1324 Caucasian men, born in 1919–1934, who had worked as business executives and managers and of whom 95.9% had retired by the year 2000. Questions on age at and type of retirement, lifestyle and chronic conditions were embedded in questionnaires.Primary and secondary outcome measuresFrailty assessed according to a modified phenotype definition at mean age 73.3 years.ResultsMean age at retirement was 61.3 years (SD 4.3) and 37.1% had ret…

Physical heaviness of work and sitting at work as predictors of mortality : a 26-year follow-up of the Helsinki Birth Cohort Study

2019

ObjectivesTo examine the relationships of late-career physical heaviness of work and sitting at work with mortality. A national-level job exposure matrix was used to determine the occupation-specific level of physical heaviness and sitting.DesignProspective cohort study between years 1990 and 2015.SettingCommunity.Participants5210 men and 4725 women from the Helsinki Birth Cohort Study with an occupational code at baseline (ages 45–57 years).Primary and secondary outcome measuresTotal, cardiovascular (International Classification of Diseases 10th Revision I00–I99), cancer (C00–C97) and external (S00–Y84) mortality.ResultsThe exposures, physical heaviness and sitting had a non-linear, invers…

Risk assessment of Bundeswehr (German Federal Armed Forces) permethrin-impregnated battle dress uniforms (BDU).

2007

In an age when vector-borne diseases are emerging worldwide, personal protective measures are essential for shielding soldiers and other exposed persons from arthropod attack. The development of permethrin-impregnated clothing has been one recent advance in protecting persons at-risk. However, to date risk assessment has not been performed related to wearing permethrin-impregnated clothing over longer time periods. Therefore, this paper describes relevant toxicological aspects of permethrin and estimates the extent of dermal permethrin uptake by soldiers wearing impregnated uniforms by determining urine metabolites of permethrin. The exposure monitoring conducted in wearers of untreated uni…

ObjectiveMany people of all ages suffer from vertigo due to different reasons. The comparison of patient data with standard values can highlight deteriorations or changes in postural control and thus indicate, for example, an increased risk of falling. Our aim is to measure standard values for the postural control of young healthy women.DesignObservational study.SettingInstitute of Occupational Medicine, Social Medicine and Environmental Medicine, Goethe-University Frankfurt/Main.Participants106 healthy German female subjects aged between 21 and 30 years (25±2.7 years) were measured. Their average body mass index (BMI) was 21.1±2.61 kg/m².Outcome measuresA pressure measuring platform was us…
