Katamnese und Lebenszufriedenheit von Kindern und Jugendlichen mit Geschlechtsidentitätsstörungen
(2014)
Die Behandlung von Kindern und Jugendlichen mit Geschlechtsidentitätsstörungen (GIS) wird seit dem Beginn der pubertätshemmenden Hormontherapie in den neunziger Jahren international kontrovers diskutiert. Diese Störung scheint bei Kindern durch psychotherapeutische Intervention besser behandelbar als bei Jugendlichen. Erwartet wurden weniger psychopathologische Auffälligkeiten und eine höhere Lebenszufriedenheit bei umfassender psychotherapeutischer Begleitung. Des Weiteren wurden die Hypothesen geprüft, dass sich ein Geschlechtswechsel ebenfalls positiv auf Lebenszufriedenheit und Psychopathologie auswirkt.
Es nahmen insgesamt 37 Kinder, Jugendliche und Erwachsene an der schriftlichen Nachuntersuchung teil, die mindestens drei Jahre vor Studienbeginn aufgrund der Diagnose GIS des Kindes- und Jugendalters in der KJP Frankfurt vorgestellt wurden. Erfasst wurden Daten zur Geschlechtsidentität, zum Behandlungsverlauf und zur sexuellen Orientierung, zur Ausprägung der Psychopathologie laut altersangemessenem Screening-Inventar (CBCL, YSR, YASR) und zur Lebenszufriedenheit mithilfe des Inventars zur Erfassung der Lebensqualität bei Kindern und Jugendlichen (ILK). Außerdem wurden die Ausprägung der Psychopathologie (erfasst mit dem CBCL und oder YSR) bei der Erstvorstellung in der Klinik mit der jetzigen Einschätzung verglichen.
Die erhobenen Daten geben keinen Hinweis darauf, dass umfangreiche Psychotherapie oder ein Geschlechtswechsel zu einer höheren Lebenszufriedenheit und einer Verbesserung der Psychopathologie führen. Im Laufe der Zeit kam es zu einer signifikanten Reduktion der Werte der Syndromskalen soziale Probleme und aggressives Verhalten bei allen Studienteilnehmern. Allerdings wurde ein signifikanter Zusammenhang zwischen der Lebenszufriedenheit im Bereich seelische Gesundheit und der Zufriedenheit mit ihrer Psychotherapie gefunden. Die Drop-out-Analyse zeigte, dass Betroffene mit einer unbewältigten Problematik im Zusammenhang mit ihrer GIS eher nicht bereit waren, an dieser Studie teilzunehmen. Des Weiteren ergab sich, dass sich in der Gruppe der Studienteilnehmer signifikant mehr Personen für einen Geschlechtswechsel entschieden haben als in der Gruppe der Studienabbrecher.
Aus den Ergebnissen lässt sich ableiten, dass alle Teilnehmer der Nachuntersuchung mit ihrem Lebensweg gleichsam zufrieden sind, unabhängig vom Ausmaß der Psychotherapie und der Entscheidung für einen Geschlechtswechsel. Außerdem haben alle Personen der Stichprobe heute weniger Probleme mit aggressivem Verhalten und weniger soziale Probleme.
Da von einer Verzerrung der Stichprobe durch einen systematischen Ausfall von Teilnehmern auszugehen ist, sind weitere Nachuntersuchungen nötig, um die Hypothesen dieser Arbeit weiter zu überprüften. Darüber hinaus gilt es zu klären, ob bestimmte Psychotherapieformen bei einigen Patienten effektiver als andere sind.
The question of whether most gliomas are infected with human cytomegalovirus (HCMV) has been under dispute for more than 10 years. We recently reported our failure to detect HCMV in gliomas in Neuro-Oncology.1 Our article was accompanied by 2 related editorials,2,3 one of which boldly criticized our approach.3 Instead of fighting a petty, ivory tower dispute, we would like to lobby for a serious collaborative approach to providing conclusive evidence on the presence of HCMV in glioma (and other cancers). Since we developed the concept of oncomodulation (ie, that HCMV …
Surface disinfectants are part of broader preventive strategies preventing the transmission of bacteria, fungi and viruses in medical institutions. To evaluate their virucidal efficacy, these products must be tested with appropriate model viruses with different physico-chemical properties under conditions representing practical application in hospitals.
The aim of this study was to evaluate a quantitative carrier assay. Furthermore, different putative model viruses like adenovirus type 5 (AdV-5) and different animal parvoviruses were evaluated with respect to their tenacity and practicability in laboratory handling. To evaluate the robustness of the method, some of the viruses were tested in parallel in different laboratories in a multi-center study. Different biocides, which are common active ingredients of surface disinfectants, were used in the test. After drying on stainless steel discs as the carrier, model viruses were exposed to different concentrations of three alcohols, peracetic acid (PAA) or glutaraldehyde (GDA), with a fixed exposure time of 5 minutes. Residual virus was determined after treatment by endpoint titration.
All parvoviruses exhibited a similar stability with respect to GDA, while AdV-5 was more susceptible. For PAA, the porcine parvovirus was more sensitive than the other parvoviruses, and again, AdV-5 presented a higher susceptibility than the parvoviruses. All parvoviruses were resistant to alcohols, while AdV-5 was only stable when treated with 2-propanol. The analysis of the results of the multi-center study showed a high reproducibility of this test system.
In conclusion, two viruses with different physico-chemical properties can be recommended as appropriate model viruses for the evaluation of the virucidal efficacy of surface disinfectants: AdV-5, which has a high clinical impact, and murine parvovirus (MVM) with the highest practicability among the parvoviruses tested.
Der Begriff Hirndoping beschreibt die Einnahme von Medikamenten mit dem Ziel der geistigen Leistungssteigerung. Diese Medikamente sind verschreibungspflichtig und bei den Konsumenten medizinisch nicht indiziert, werden also zweckentfremdet. Mittlerweile ist aus dem Thema Hirndoping ein Thema geworden, welches öffentlich diskutiert wird. Zeitung, Presse und sogar die Film- und Fernsehindustrie beschäftigen sich mit diesem Thema. So nimmt unter anderem die gestresste Mutter Lynette aus der US-Serie «Desperate Housewives» die Ritalin-Tablette ihres Sohnes ein, um so den anstrengenden Alltag besser meistern zu können. In dem US-Film «Ohne Limit - Die Droge für Reichtum und Macht» dreht sich alles um eine Droge, welche die Leistungsfähigkeit ins unermessliche steigern kann.
In der aktuellen Presse findet man immer öfter Schlagzeilen wie beispielsweise Folgendes: „Studenten unter Druck: Hirndoping kein Massenphänomen“.
Doch auch die Lebensmittel- und Pharmaindustrie ist beim Thema Leistungssteigerung in der Ideenfindung sehr kreativ. Manche Substanzen „verleihen einem Flügel“ (Red Bull®), andere sind lecker in Schokolade eingepackt (Pocket Coffee®) und wieder andere sollen die Menschen geistig aktiver machen (Gingium®).
Der Großteil der bisherigen Studien zum Thema Hirndoping stammt aus den Vereinigten Staaten von Amerika. Erst seit kurzer Zeit wird auch die Prävalenz von Hirndoping in Deutschland untersucht. Wie viele Schülerinnen und Schüler sowie Studentinnen und Studenten Substanzen zur geistigen Leistungssteigerung einnehmen, wurde teils schon für bestimmte Regionen und bestimmte Fachrichtungen stichprobenartig ermittelt. Bisher liegen allerdings noch keine umfangreichen Daten zur Prävalenz von Hirndoping bei Medizinstudenten vor. Daher untersuchte diese Studie die Einnahme von Leistungssteigernden Substanzen bei Medizinstudenten in Frankfurt am Main.
Zu den exzellenten Frankfurter Neurowissenschaftlern des 20. Jahrhunderts zählt Kurt Goldstein. Er durchlief die harte Schule von Ludwig Edinger. Bekannt wurde er jedoch durch einen eigenständigen Ansatz, der mit dem Schlagwort ganzheitliche Neurologie charakterisiert werden kann. Er wandte sich gegen die Auffassung, »Funktionen« im Gehirn exakt lokalisieren zu können, ohne den lokalisatorischen Ansatz vollständig zu verwerfen. Besondere Aufmerksamkeit schenkte er den Kompensationsreaktionen des Gehirns und des »ganzen« Menschen. » […] he never forgot that he addressed an individual, not a brain«, brachte es sein Schüler Walther Riese auf den Punkt.
Changes in vitamin D serum levels have been associated with inflammatory diseases, such as inflammatory bowel disease (IBD), rheumatoid arthritis, systemic lupus erythematosus, multiple sclerosis (MS), atherosclerosis, or asthma. Genome- and transcriptome-wide studies indicate that vitamin D signaling modulates many inflammatory responses on several levels. This includes (i) the regulation of the expression of genes which generate pro-inflammatory mediators, such as cyclooxygenases or 5-lipoxygenase, (ii) the interference with transcription factors, such as NF-κB, which regulate the expression of inflammatory genes and (iii) the activation of signaling cascades, such as MAP kinases which mediate inflammatory responses. Vitamin D targets various tissues and cell types, a number of which belong to the immune system, such as monocytes/macrophages, dendritic cells (DCs) as well as B- and T cells, leading to individual responses of each cell type. One hallmark of these specific vitamin D effects is the cell-type specific regulation of genes involved in the regulation of inflammatory processes and the interplay between vitamin D signaling and other signaling cascades involved in inflammation. An important task in the near future will be the elucidation of the regulatory mechanisms that are involved in the regulation of inflammatory responses by vitamin D on the molecular level by the use of techniques such as chromatin immunoprecipitation (ChIP), ChIP-seq, and FAIRE-seq.
