Manifestation allergischer Krankheiten bei jungen Erwachsenen in Zusammenhang mit dem Eintritt in das Berufsleben - Untersuchungen zur Abhängigkeit von arbeitsbedingten Faktoren unter Berücksichtigung von Vorerkrankungen, Disposition und außerberuflichen Umweltfaktoren und Ableitung von Vorschlägen zur verbesserten Prävention: Studie in Ost- und Westdeutschland zu beruflichen Allergierisiken - SOLAR II -; Abschlussbericht
SOLAR II ist das zweite Follow-up einer bevölkerungsbezogenenden Kohorten-Studie. Diese Studie basiert auf einer Kohorte, die 1995/1996 aus damals 9-11jährigen Kindern aus Dresden und München zusammengestellt wurde. Die inzwischen erwachsenen Teilnehmer wurden nun erneut mit dem Ziel untersucht, Zusammenhänge zwischen beruflichen Expositionen und Allergien und Atemwegserkrankungen zu ermitteln. Ein Schwerpunkt der Auswertung galt der Frage, wie sich aus Risikofaktoren, die bereits in der Kindheit erkennbar sind, vorhersagen lässt, dass sich bei Tätigkeitsbeginn in Berufen mit hoher Exposition eine Allergie oder eine Atemwegserkrankung entwickeln wird. Mit den Ergebnissen der Studie kann nicht begründet werden, Jugendlichen mit Risikofaktoren für allergische Atemwegserkrankungen grundsätzlich von Tätigkeiten mit hohem Expositions-Potenzial abzuraten. Die Autoren sprechen sich aber für eine engmaschige arbeitsmedizinische Betreuung junger Erwachsener aus, die am Beginn einer solchen Tätigkeit stehen
Pregnancy and perinatal conditions and atopic disease prevalence in childhood and adulthood
BACKGROUND: Previous studies showed controversial results for the influence of pregnancy-related and perinatal factors on subsequent respiratory and atopic diseases in children. The aim of this study was to assess the association between perinatal variables and the prevalence of asthma, bronchial hyperreactivity (BHR), flexural eczema (FE), allergic rhinitis, and sensitization in childhood and early adulthood.
METHODS: The studied population was first examined in Munich and Dresden in 1995/1996 at age 9-11 years. Participants were followed until age 19-24 years using questionnaires and clinical examinations. Associations between perinatal data and subsequent atopic diseases were examined using logistic regression analyses adjusting for potential confounders.
RESULTS: Cesarean section was statistically significantly associated with BHR in early adulthood (odds ratio 4.8 [95% confidence interval 1.5-15.2]), while assisted birth was associated with presence of asthma symptoms in childhood (2.2 [1.2-3.9]), FE symptoms (2.2 [1.2-4.3]) and doctor's diagnosis of atopic dermatitis (1.9 [1.0-3.4]) in childhood, and sensitization in early adulthood (2.2 [1.1-4.3]). Lower birth length (1.9 [1.1-3.2]), lower birthweight (0.5 [0.3-0.9]), and higher birthweight (0.6 [0.4-1.0]) were predictive of sensitization in early adulthood compared to average birth length and birthweight, respectively. None of the other perinatal factors showed statistically significant associations with the outcomes.
CONCLUSIONS: Our results indicate that children who are born by cesarean section and especially by assisted birth, might be at greater risk for developing asthma, FE, and sensitization and should hence be monitored. Prenatal maternal stress might partly explain these associations, which should be further investigated

Metabolism of fluoroorganic compounds in microorganisms: Impacts for the environment and the production of fine chemicals
Incorporation of fluorine into an organic compound can favourably alter its physicochemical
properties with respect to biological activity, stability and lipophilicity. Accordingly, this
element is found in many pharmaceutical and industrial chemicals. Organofluorine
compounds are accepted as substrates by many enzymes, and the interactions of
microorganisms with these compounds are of relevance to the environment and the fine
chemicals industry. One the one hand the microbial transformation of fluorinated compounds
can lead to the generation of toxic compounds that are of environmental concern, yet similar
biotransformations can yield difficult-to-synthesise products and intermediates, in particular
derivatives of biologically active secondary metabolites. In this paper we review the
historical and recent developments of organofluorine biotransformation in microorganisms,
and highlight the possibility of using microbes as models of fluorinated drug metabolism in
mammals.Author has checked copyrightAD 28/01/201
