A common biological basis of obesity and nicotine addiction
2013
Contains fulltext : 128630.pdf (Publisher’s version ) (Open Access) Smoking influences body weight such that smokers weigh less than non-smokers and smoking cessation often leads to weight increase. The relationship between body weight and smoking is partly explained by the effect of nicotine on appetite and metabolism. However, the brain reward system is involved in the control of the intake of both food and tobacco. We evaluated the effect of single-nucleotide polymorphisms (SNPs) affecting body mass index (BMI) on smoking behavior, and tested the 32 SNPs identified in a meta-analysis for association with two smoking phenotypes, smoking initiation (SI) and the number of cigarettes smoked …
Sequence variants at CHRNB3-CHRNA6 and CYP2A6 affect smoking behavior
2010
Contains fulltext : 89305.pdf (Publisher’s version ) (Closed access) Smoking is a common risk factor for many diseases. We conducted genome-wide association meta-analyses for the number of cigarettes smoked per day (CPD) in smokers (n = 31,266) and smoking initiation (n = 46,481) using samples from the ENGAGE Consortium. In a second stage, we tested selected SNPs with in silico replication in the Tobacco and Genetics (TAG) and Glaxo Smith Kline (Ox-GSK) consortia cohorts (n = 45,691 smokers) and assessed some of those in a third sample of European ancestry (n = 9,040). Variants in three genomic regions associated with CPD (P < 5 x 10(-8)), including previously identified SNPs at 15q25 repre…
Psykoosilääkehoidon ohjaus voi tehostaa skitsofrenian hoitoa
2022
Psykoosilääkkeet lievittävät skitsofrenian psykoosioireita ja vähentävät relapsiriskiä. Psykoosilääkityksen pitkäaikaiskäytön hyöty-haittasuhde skitsofrenian hoidossa on osin tuntematon. Etenkin suurten psykoosilääkeannosten pitkäaikaiskäyttö voi altistaa metabolisille, neurologisille, kognitiivisille ja psykologisille haitoille. Psykoosilääkehoidon haittoja voidaan minimoida systemaattisella lääkehoidon ohjauksella, jossa lääkehoito suunnitellaan ja toteutetaan moniammatillisessa yhteistyössä potilaan ja hänen läheistensä kanssa. Lääkehoidon ohjaus voi auttaa käyttämään pienintä vaikuttavaa hoitoannosta sekä parantaa hoitoon sitoutumista ja hoidon tuloksellisuutta. Skitsofrenian psykoosilä…
Genome-wide association and genetic functional studies identify autism susceptibility candidate 2 gene (AUTS2) in the regulation of alcohol consumpti…
2011
Alcohol consumption is a moderately heritable trait, but the genetic basis in humans is largely unknown, despite its clinical and societal importance. We report a genome-wide association study meta-analysis of ∼2.5 million directly genotyped or imputed SNPs with alcohol consumption (gram per day per kilogram body weight) among 12 population-based samples of European ancestry, comprising 26,316 individuals, with replication genotyping in an additional 21,185 individuals. SNP rs6943555 in autism susceptibility candidate 2 gene ( AUTS2 ) was associated with alcohol consumption at genome-wide significance ( P = 4 × 10 −8 to P = 4 × 10 −9 ). We found a genotype-specific expression of AUTS2 in 9…
Early developmental milestones in adult schizophrenia and other psychoses. A 31-year follow-up of the Northern Finland 1966 Birth Cohort
2001
Abstract Delayed childhood development may precede adult psychoses. We tested this hypothesis in a large, general population birth cohort (n=12 058) followed to age 31 years. The ages at which individuals learned to stand, walk, speak, and became potty-trained (bowel control) and dry (bladder control), were recorded at a 1-year examination. Psychiatric outcome was ascertained through linkage to a national hospital discharge register. Cumulative incidence of DSM-III-R schizophrenia, other psychoses and non-psychotic disorders were stratified according to the timing of milestones and compared within the cohort using internal standardization. 100 cases of DSM-III-R schizophrenia, 55 other psyc…
Verbal learning and memory and their associations with brain morphology and illness course in schizophrenia spectrum psychoses.
2012
The California Verbal Learning Test and structural brain imaging were administered to 57 subjects with schizophrenia spectrum disorders and 94 controls in a general population sample. Cases had lower semantic cluster scores. Poorer verbal memory strategies were associated with longer duration of illness and heavier use of antipsychotic medication. After controlling for duration of illness, sex, and total gray matter, poorer verbal memory was associated with lower gray matter volume in the cingulate cortex, juxtapositional lobule, right superior temporal gyrus, and precuneus. After controlling for use of antipsychotic medication, there was an association between higher serial clustering and …
