An evaluation of exposure metrics in an epidemiologic study on radio and television broadcast transmitters and the risk of childhood leukemia.

2009

Electric field strength values calculated by wave propagation modeling were applied as an exposure metric in a case–control study conducted in Germany to investigate a possible association between radio frequency electromagnetic fields (RF-EMF) emitted from television and radio broadcast transmitters and the risk of childhood leukemia. To validate this approach it was examined at 850 measurement sites whether calculated RF-EMF are an improvement to an exposure proxy based on distance from the place of residence to a transmitter. Further, the agreement between measured and calculated RF-EMF was explored. For dichotomization at the 90% quantiles of the exposure distributions it was found that…

Loneliness predicts suicidal ideation and anxiety symptoms in long-term childhood cancer survivors.

2020

Abstract Background/Objective Long-term childhood cancer survivors (CCS) are at risk for adverse late effects. However, not all of them are well understood. The present study addressed loneliness, a previously under-researched mental health risk in cancer survivor populations. We assessed the prevalence of loneliness and its impact on psychological symptoms over time. Method: A registry-based sample of N = 633 adult long-term CCS underwent medical and psychological assessments and took part in a follow-up survey 2.5 years later. Psychological symptoms (somatic, anxiety, depression symptoms, and suicidal ideation) were measured using the Patient Health Questionnaire. We calculated linear reg…

Japanese Radiation Research Society

2017

Computed tomography (CT) is an essential tool in modern medicine and is frequently used to diagnose a wide range of conditions, particularly in industrial countries, such as Japan and Germany. However, markedly higher doses of ionizing radiation are delivered during CT imaging than during conventional X-ray examinations. To assess pediatric CT practice patterns, data from three university hospital databases (two in Japan and one in Germany) were analyzed. Anonymized data for patients aged 0 to 14 years who had undergone CT examinations between 2008 and 2010 were extracted. To assess CT practice, an interdisciplinary classification scheme for CT indications, which incorporated the most commo…

Air pollution and airport apron workers: A neglected occupational setting in epidemiological research.

2020

Abstract Introduction Airport apron workers are occupationally exposed to jet exhaust and major concern is related to the exposure to ultrafine particles (UFP) from aircrafts. To date, little attention has been given to occupational exposures to aircraft-related UFP, although aircraft engines have high emissions of ultrafine particles, which are orders of magnitude higher than residential exposure. UFP could possibly contribute to the development of cancer, heart disease, mental illness, and respiratory symptoms. In addition to particulate matter, apron workers are exposed to other polluting substances associated with vehicles, aircraft exhaust or direct fuel emissions. Methods We performed…

The desire for children among adult survivors of childhood cancer: Psychometric evaluation of a cancer-specific questionnaire and relations with soci…

2019

OBJECTIVE Long-term childhood cancer survivors (CCS) are less likely to become parents than their peers of the same age. Previous research has suggested that besides fertility, this outcome is shaped by psychosocial factors such as emotional motives toward having a child. Drawing from a sample of CCS with survival times >25 years, we present the validation of a questionnaire assessing cancer-specific reproductive motives and concerns. METHODS We evaluated the cancer-specific version of the Leipzig Questionnaire of Motives to have a Child (LKM-C) in a register-based sample of adult CCS (N = 632, 31% had children, 44.5% women). We conducted a confirmatory factor analysis and tested associatio…

Kindliche Leukämien und EMF-Expositionen in der Umgebung hochfrequenter Sendestationen (KiSS) – Fragestellung und Studienbeschreibung

2018

Abstract. Im Rahmen einer Fall-Kontroll-Studie wird untersucht, ob es einen Zusammenhang zwischen dem Leukämierisiko bei Kindern und der Exposition gegenüber elektromagnetischen Feldern in der Umgebung leistungsstarker Sendestationen von Rundfunk und Fernsehen gibt. Bislang wurden fünf Studien im Umkreis von Rundfunksendeanlagen durchgeführt. Deren Aussagekraft ist jedoch durch eine grobe Expositionsabschätzung und ihren ökologischen Studienansatz ohne individuelle Expositionsbestimmung limitiert. Wesentliches Element der hier vorgestellten Studie ist dagegen eine individuelle Expositionsabschätzung, die zum einen auf der Geocodierung von Wohnadressen und Expositionspunktquellen und zum and…

2021

The growing population of long-term childhood cancer survivors is at increased risk for severe, therapy-related late effects and premature mortality. The cardiac and vascular late sequelae in long-term survivors of childhood cancer (CVSS) study is a cohort of patients from Germany diagnosed with a neoplasia prior to 15 years of age in the time period 1980 to 1990. Late mortality was evaluated in a total of 4505 individuals who survived 5 years or more after the initial diagnosis (5-year survivors). Survivors with a second primary tumor were excluded. Standardized mortality ratios (SMRs) were calculated. By December 2014, 400 patients had died. Available cause of death information from 188 i…
