Endogén pszichózisok klinikuma, összehasonlító nozológiája, genetikai, pszichometriai szociológiai és experimentális vizsgálata, 21-33 éves követéses vizsgálatuk alapján = Clinical, sociological, psychometric, experimental, genetic research and comparative nosology, of functional psychoses based on their 21-33-year follow through investigation

A hagyományos pszichopatológiában manifeszt és látens tünetek között észlelhető "szakadék" feltöltését az úgynevezett "alaptünetek" általunk alkotott becslésskálába foglalásának és az általunk konceptualizált Morbaffin Személyiségtípusok Skáláinak az alkalmazásával mutattuk meg. A "Spontán önjellemzés" innovációt bevezetve sajátos megoszlást mutattunk ki egyfelől normálkontroll személyek vs. betegek, másfelől különböző betegcsoportok között. Egy másik innovációnk a "reliabilitás validitása" terminus bevezetése és verifikálása. Ezt a negyed évszázad időkülönbséggel felvett pontozó skálák és a vizsgáló pontozók közötti egyezések vizsgálatával verifikáltuk. Ajánljuk a rendszeresítését. A Wechsler intelligenciateszt morbospecificitásának komparatív nozológiai vizsgálata során szignifikáns deficiteket mutattunk ki a 21-33 éves kórlefolyásban. Tudomásunk szerint elsőként vizsgáltuk meg a Leonhardi nozológiai rendszer validitását hosszú távú követéses katamnesztikus felméréssel. Ezt a nozológiai osztályozást egy sor összefüggésben validnak találtuk. Megállapítottuk a hallucináció hosszú távú változásainak nozospecifikus mintáit. A témavezető tudomány-logikai elemzést írt a pszichiátriai jelenlegi kríziséről. Továbbá két határterületi kérdést elemzett: "Szellem és kórságai", "Deviancia és rendszerváltozás". Kimutattuk, hogy a szám-szimbólum teszttel mért neurokognitív deficit a betegségfolyamat intenzitásának és tartamának függvénye. Pethő Bertalan | We demonstrated the relevance of a special psychopathological dimension between the definitive symptoms on one hand and the latent disturbances on the other by using two rating scales developed by us. We have found nosospecific pattern by introducing an innovative term and method named "Spontaneous self-characterization". Based on analyses of the data of psychopathological rating scales on one hand and on analyses of ratings of independent investigators on the other we introduced the new term "of reliability". We verified it by comparison of two series of assessments of the same population followed-up after a quarter of century. Using the Wechsler Intelligence Scale we have found nosospecific patterns of deficits being manifested in the 21-33-year course of illness. To our knowledge no previous long-term studies of the Leonhardean classification of endogenous psychoses have been conducted. Our prospective study started in 1967-1976. The same population was followed-up by participation of a "blind control" psychiatrist in 1997-2002. Hebephrenias, group of normal persons, of schizophrenias and of systematic paraphrenias proved to be valid. Bipolar manic-depressive psychoses, cycloid psychoses and unipolar depression were also valid by forming "nosological families". The digit symbol coding impairment was found to represent the disease process, which ultimately results in a "defect-state". Bertalan Peth

Shotgun Analysis of Gut Microbiota with Body Composition and Lipid Characteristics in Crohn’s Disease

Alterations to intestinal microbiota are assumed to occur in the pathogenesis of inflammatory bowel disease (IBD). This study aims to analyze the association of fecal microbiota composition, body composition, and lipid characteristics in patients with Crohn’s disease (CD). In our cross-sectional study, patients with CD were enrolled and blood and fecal samples were collected. Clinical and endoscopic disease activity and body composition were assessed and laboratory tests were made. Fecal bacterial composition was analyzed using the shotgun method. Microbiota alterations based on obesity, lipid parameters, and disease characteristics were analyzed. In this study, 27 patients with CD were analyzed, of which 37.0% were obese based on visceral fat area (VFA). Beta diversities were higher in non-obese patients (p < 0.001), but relative abundances did not differ. C. innocuum had a higher abundance at a high cholesterol level than Bacillota (p = 0.001, p = 0.0034). Adlercreutzia, B. longum, and Blautia alterations were correlated with triglyceride levels. Higher Clostridia (p = 0.009) and B. schinkii (p = 0.032) and lower Lactobacillus (p = 0.035) were connected to high VFA. Disease activity was coupled with dysbiotic elements. Microbiota alterations in obesity highlight the importance of gut microbiota in diseases with a similar inflammatory background and project therapeutic options

Prolonged activity of the transposase helper may raise safety concerns during DNA transposon-based gene therapy

DNA transposon-based gene delivery vectors represent a promising new branch of randomly integrating vector development for gene therapy. For the side-by-side evaluation of the piggyBac and Sleeping Beauty systems—the only DNA transposons currently employed in clinical trials—during therapeutic intervention, we treated the mouse model of tyrosinemia type I with liver-targeted gene delivery using both transposon vectors. For genome-wide mapping of transposon insertion sites we developed a new next-generation sequencing procedure called streptavidin-based enrichment sequencing, which allowed us to identify approximately one million integration sites for both systems. We revealed that a high proportion of piggyBac integrations are clustered in hot regions and found that they are frequently recurring at the same genomic positions among treated animals, indicating that the genome-wide distribution of Sleeping Beauty-generated integrations is closer to random. We also revealed that the piggyBac transposase protein exhibits prolonged activity, which predicts the risk of oncogenesis by generating chromosomal double-strand breaks. Safety concerns associated with prolonged transpositional activity draw attention to the importance of squeezing the active state of the transposase enzymes into a narrower time window
