Regional variation in caesarean deliveries in Germany and its causes.
BMC Pregnancy Childbirth
PUBLISHED: 04-24-2013
Show Abstract
Hide Abstract
Determinants of regional variation in caesarean sections can contribute explanations for the observed overall increasing trend of caesarean sections. We assessed which mechanism explains the higher rate of caesarean sections in the former West than East Germany: a more liberal use of caesarean sections in the case of relative indications or more common caesarean sections without indications.

Antidepressant drug use and off-label prescribing in children and adolescents in Germany: results from a large population-based cohort study.
Eur Child Adolesc Psychiatry

Hide Abstract
The off-label use of drugs in children and adolescents is widespread. In Germany, the use of selective serotonin reuptake inhibitors (SSRIs) and other antidepressants (OADs) is not licensed for the treatment of depressive disorders in children and adolescents except for fluoxetine, which was approved in 2006. Against this background, antidepressant drug (ATD) use with a particular focus on off-label prescribing was characterised in a retrospective cohort study including cross-sectional analyses based on claims data of 2,599,685 patients up to 17 years of age. Prevalence of ATD use was 1.84 (95% CI 1.78-1.90) per 1,000 children in 2004, 1.57 (95% CI 1.52-1.62) in 2005 and 1.66 (95% CI 1.61-1.72) in 2006. More than half of all children treated with ATDs (51.29%) received only one single prescription of an ATD during the study period. Of all prescribed ATDs, 11,172 (42.09%) were tricyclic antidepressants 9,179 (34.58%) were SSRIs, 4,371 (16.47%) were St Johns wort preparations and 1,821 (6.86%) were OADs. Around half of all children and adolescents who were treated with ATDs were diagnosed with depressive disorders (56.30%). Overall, 13,035 (49.11%) of all ATDs were prescribed off-label. Off-label use by age (40.18%) was found to be more common than off-label use by indication (16.63%) with 7.70% of off-label use occurring in both categories. Specialist treatment by hospital-based physicians increased the risk (odds ratio: 2.26, 95% CI 2.05-2.48) of receiving an off-label prescription compared to treatment by general practitioners. In summary, off-label use of ATDs in children and adolescents was substantial in Germany.

Comorbidities in ADHD children treated with methylphenidate: a database study.
BMC Psychiatry
PUBLISHED: 01-04-2013
Show Abstract
Hide Abstract
Methylphenidate (MPH) is the most common drug treatment of attention deficit / hyperactivity disorder (ADHD) in children. Treatment with MPH is contraindicated in the presence of certain psychiatric, cerebro- and cardiovascular conditions. We assessed MPH treatment prevalence and incidence and the frequency of comorbid conditions related to these contraindications in new MPH users compared to a control group without ADHD and ADHD medication.

Show Abstract
Hide Abstract
In a previous analysis of a case-control study of testicular cancer nested in a cohort of automobile workers, we observed an increased risk for testicular cancer among workers who had ever been involved in occupational metal-cutting tasks. We investigated whether this risk increase was due to exposure to metal-working fluids (MWF).

Regional and temporal variations in coding of hospital diagnoses referring to upper gastrointestinal and oesophageal bleeding in Germany.
BMC Health Serv Res
PUBLISHED: 08-17-2011
Show Abstract
Hide Abstract
Health insurance claims data are increasingly used for health services research in Germany. Hospital diagnoses in these data are coded according to the International Classification of Diseases, German modification (ICD-10-GM). Due to the historical division into West and East Germany, different coding practices might persist in both former parts. Additionally, the introduction of Diagnosis Related Groups (DRGs) in Germany in 2003/2004 might have changed the coding. The aim of this study was to investigate regional and temporal variations in coding of hospitalisation diagnoses in Germany.

Show Abstract
Hide Abstract
A system for retrospective occupational exposure assessment combining the efficiency of a job exposure matrix (JEM) and the precision of a subsequent individual expert exposure assessment (IEEA) was developed. All steps of the exposure assessment were performed by an interdisciplinary expert panel in the context of a case-control study on male germ cell cancer nested in the car manufacturing industries.

Cancer mortality among German aircrew: second follow-up.
Radiat Environ Biophys
PUBLISHED: 06-10-2009
Show Abstract
Hide Abstract
Aircrew members are exposed to cosmic radiation and other specific occupational factors. In a previous analysis of a large cohort of German aircrew, no increase in cancer mortality or dose-related effects was observed. In the present study, the follow-up of this cohort of 6,017 cockpit and 20,757 cabin crew members was extended by 6 years to 2003. Among male cockpit crew, the resulting all-cancer standardized mortality ratio (SMR) (n = 127) is 0.6 (95% CI 0.5-0.8), while for brain tumors it is 2.1 (95% CI 1.0-3.9). The cancer risk is significantly raised (RR = 2.2, 95% CI 1.2-4.1) among cockpit crew members employed 30 years or more compared to those employed less than 10 years. Among both female and male cabin crew, the all-cancer SMR and that for most individual cancers are close to 1. The SMR for breast cancer among female crew is 1.2 (95% CI 0.8-1.8). Non-Hodgkins Lymphoma among male cabin crew is increased (SMR 4.2; 95% CI 1.3-10.8). However, cancers associated with radiation exposure are not raised in the cohort. It is concluded that among cockpit crew cancer mortality is low, particularly for lung cancer. The positive trend of all cancer with duration of employment persists. The increased brain cancer SMR among cockpit crew requires replication in other cohorts. For cabin crew, cancer mortality is generally close to population rates. Cosmic radiation dose estimates will allow more detailed assessments, as will a pooling of updated aircrew studies currently in planning.

Cosmic radiation and mortality from cancer among male German airline pilots: extended cohort follow-up.
Eur. J. Epidemiol.
Show Abstract
Hide Abstract
Commercial airline pilots are exposed to cosmic radiation and other specific occupational factors, potentially leading to increased cancer mortality. This was analysed in a cohort of 6,000 German cockpit crew members. A mortality follow-up for the years 1960-2004 was performed and occupational and dosimetry data were collected for this period. 405 deaths, including 127 cancer deaths, occurred in the cohort. The mortality from all causes and all cancers was significantly lower than in the German population. Total mortality decreased with increasing radiation doses (rate ratio (RR) per 10 mSv: 0.85, 95 % CI: 0.79, 0.93), contrasting with a non-significant increase of cancer mortality (RR per 10 mSv: 1.05, 95 % CI: 0.91, 1.20), which was restricted to the group of cancers not categorized as radiogenic in categorical analyses. While the total and cancer mortality of cockpit crew is low, a positive trend of all cancer with radiation dose is observed. Incomplete adjustment for age, other exposures correlated with duration of employment and a healthy worker survivor effect may contribute to this finding. More information is expected from a pooled analysis of updated international aircrew studies.

What is Visualize?

JoVE Visualize is a tool created to match the last 5 years of PubMed publications to methods in JoVE's video library.

How does it work?

We use abstracts found on PubMed and match them to JoVE videos to create a list of 10 to 30 related methods videos.

Video X seems to be unrelated to Abstract Y...

In developing our video relationships, we compare around 5 million PubMed articles to our library of over 4,500 methods videos. In some cases the language used in the PubMed abstracts makes matching that content to a JoVE video difficult. In other cases, there happens not to be any content in our video library that is relevant to the topic of a given abstract. In these cases, our algorithms are trying their best to display videos with relevant content, which can sometimes result in matched videos with only a slight relation.
