- BACKGROUND/AIM: Patients with inflammatory bowel disease (IBD) have more work disability than the general population. We aimed to estimate the monetary cost of IBD for the individual through assessment of earnings in relation to diagnosis.METHODS: Through linkage of national registers we identified patients aged 30-55 years at first IBD diagnosis in Sweden 2002-2011, and same-sex IBD-free siblings. We estimated taxable earnings and disposable income from 5 years before to 5 years after diagnosis.RESULTS: The 5,961 patients (27% Crohn's disease, 68% ulcerative colitis, 4.3% IBD unclassified) had similar taxable earnings as their 7,810 siblings until the year of diagnosis, when earnings decreased and remained lower than in siblings during follow-up. The adjusted difference in earnings over the entire 5-year period after diagnosis was -5% (-8,212€; 95%CI: -11,458 to-4,967). The difference was larger in women than in men, and larger in Crohn's disease than in ulcerative colitis. When stratifying for sex and IBD subtype and comparing earnings during each year of follow-up, the median annual earnings were lower in women with Crohn's disease and ulcerative colitis than in their sisters during all years of follow-up, whereas the men had similar annual taxable earnings as their brothers. The disposable income was similar between patients and siblings during the investigated time period.CONCLUSION: From the year of diagnosis and at least 5 years onwards, patients with IBD had 5% lower earnings than siblings, mainly explained by differences between women with IBD and their sisters. However, there were no differences in disposable income.

- BACKGROUND: To avoid a permanent stoma, restorative surgery is performed after the colectomy. Previous studies have shown that less than half of patients with ulcerative colitis undergo restorative surgery.OBJECTIVE: The primary aim was to explore the association between socioeconomic status and restorative surgery after colectomy.DESIGN: This was a nationwide register-based cohort study.SETTINGS: The study was conducted in Sweden.PATIENTS: All Swedish patients with ulcerative colitis who underwent colectomy between 1990 and 2017 at the age of 15 to 69 years were included.MAIN OUTCOME MEASURES: The main outcome was restorative surgery, and the secondary outcome was failure of the reconstruction (defined as the need for a new ileostomy after the reconstruction or nonreversal of a defunctioning stoma within 2 years of the reconstruction). To calculate HRs for restorative surgery after colectomy, as well as failure after restorative surgery, multivariable Cox regression models were performed (adjusted for sex, year of colectomy, colorectal cancer diagnosis, education, civil status, country of birth, income (quartiles 1 to 4, where Q4 represents highest income), hospital volume, and stratified by age).RESULTS: In all, 5969 patients with ulcerative colitis underwent colectomy, and of those, 2794 (46.8%) underwent restorative surgery. Restorative surgery was more common in patients with a high income at the time of colectomy (quartile 1, reference; quartile 2, 1.09 (0.98-1.21); quartile 3, 1.20 (1.07-1.34); quartile 4, 1.27 (1.13-1.43)) and less common in those born in a Nordic country than in immigrants born in a non-Nordic country (0.86 (0.74-0.99)), whereas no association was seen with educational level and civil status. There was no association between socioeconomic status and the risk of failure after restorative surgery.LIMITATIONS: The study was restricted to register data.CONCLUSIONS: Restorative surgery in ulcerative colitis appears to be more common in patients with a high income and patients born in a non-Nordic country, indicating inequality in the provided care.

- Lay Summary: This population-based study of 2172 patients treated with colectomy for ulcerative colitis shows that a colectomy and restorative IRA/IPAA surgery performed simultaneously entails a higher risk of failure than when reconstruction is performed later.Background: Restorative surgery after colectomy due to ulcerative colitis (UC) may be performed simultaneously with colectomy (primary) or as a staged procedure. Risk factors for failure after restorative surgery are not fully explored. This study aimed to compare the risk of failure after primary and staged reconstruction.Methods: This is a national register-based cohort study of all patients 15 to 69 years old in Sweden treated with colectomy due to UC and who received an ileorectal anastomosis (IRA) or ileal pouch-anal anastomosis (IPAA) between 1997 and 2017. Failure was defined as a reoperation with new ileostomy after restorative surgery or a remaining defunctioning ileostomy after 2 years. Risk of failure was calculated using the Kaplan-Meier method and Cox regression adjusted for sex, age, calendar period, primary sclerosing cholangitis, and duration of UC.Results: Of 2172 included patients, 843 (38.8%) underwent primary reconstruction, and 1329 (61.2%) staged reconstruction. Staged reconstruction was associated with a decreased risk of failure compared with primary reconstruction (hazard ratio, 0.73; 95% CI, 0.58-0.91). The 10-year cumulative risk of failure was 15% vs 20% after staged and primary reconstruction, respectively. In all, 1141 patients (52.5%) received an IPAA and 1031 (47.5%) an IRA. In stratified multivariable models, staged reconstruction was more successful than primary reconstruction in both IRA (hazard ratio, 0.75; 95% CI, 0.54-1.04) and IPAA (hazard ratio, 0.73; 95% CI, 0.52-1.01), although risk estimates failed to attain statistical significance.Conclusions: In UC patients undergoing colectomy, postponing restorative surgery may decrease the risk of failure.

- Receptors of the 5-HT2C subtype are of importance for the influence of serotonin on food intake, and 2 single nucleotide polymorphisms in this gene (HTR2C)-Cys23Ser (rs6318) and -759C>T (rs3813929)-have been reported to be associated with weight and/or antipsychotic-induced weight gain. The present study aimed to replicate these associations; in addition, the 5-HTTLPR polymorphism in the promoter region of the serotonin transporter gene (SLC6A4) was assessed. The polymorphisms were genotyped in subjects recruited from the normal population (n = 510), and possible associations between genotype and body mass index (BMI) were assessed. The Ser23 allele was more common in underweight subjects (BMI <20) than in normal- and overweight (BMI >/=20) subjects (P = .006). The T allele of the -759C/T polymorphism was less common in the overweight group (BMI >/=25) (P = .007). Homozygosity for the short allele of 5-HTTLPR was more frequent in underweight subjects (P = .015). Our results are in agreement with previous studies, suggesting polymorphisms in HTR2C to be associated with body weight, particularly in women; and they also suggest that 5-HTTLPR may influence this phenotype. Further studies on the importance of the investigated genes for eating disorders and drug-induced weight gain are warranted.

- The efficacy of serotonin reuptake inhibitors in depression and anxiety disorders suggests the gene coding for the serotonin transporter (5-HTT), SLC6A4, as a candidate of importance for these conditions. Positive findings regarding associations between polymorphisms in SLC6A4 have been reported, indicating that these polymorphisms may influence anxiety-related personality traits, as well as the risk of developing depression and suicidality. Serotonin 5-HTT availability was assessed with single photon emission computed tomography (SPECT), using I-123-beta-CIT as ligand, in a population of unmedicated male suicide attempters (n=9) and in matched controls (n=9). Two polymorphisms in SLC6A4 were assessed, including the 5-HTTLPR located in the promoter region and a variable number of tandem repeats (VNTR) polymorphism in intron 2 (STin2). In suicide attempters, but not in controls, low 5-HTT availability was associated with the S allele of 5-HTTLPR and with the 12 repeat allele of STin2. Data suggest that polymorphisms in SLC6A4 may influence the expression of the brain serotonin transporter in suicide attempters.

- Social memory, including the ability to recognize faces and voices, is essential for social relationships. It has a large heritable component, but the knowledge about the contributing genes is sparse. The genetic variation underlying inter-individual differences in social memory was investigated in an exploratory sample (n = 55), genotyped with a chip comprising approximately 200,000 single nucleotide polymorphisms (SNPs), and in a validation sample (n = 582), where 30 SNPs were targeted. In the exploratory study face identity recognition was measured. The validation study also measured vocal sound recognition, as well as recognition of faces and vocal sounds combined (multimodal condition). In the exploratory study, the 30 SNPs that were associated with face recognition at puncorrected < 0.001 and located in genes, were chosen for further study. In the validation study two of these SNPs showed significant associations with recognition of faces, vocal sounds, and multimodal stimuli: rs1800779 in the gene encoding nitric oxide synthase 3 (NOS3) and rs3807370 in the gene encoding the voltage-gated channel, subfamily H, member 2 (KCNH2), in strong linkage disequilibrium with each other. The uncommon alleles were associated with superior performance, and the effects were present for men only (p < 0.0002). The exploratory study also showed a weaker but significant association with (non-emotional) word recognition, an effect that was independent of the effect on face recognition. This study demonstrates evidence for an association between NOS3 and KCNH2SNPs and social memory.

- Autism is a highly heritable disorder but the specific genes involved remain largely unknown. The higher prevalence of autism in men than in women, in conjunction with a number of other observations, has led to the suggestion that prenatal brain exposure to androgens may be of importance for the development of this condition. Prompted by this hypothesis, we investigated the potential influence of variation in the androgen receptor (AR) gene on the susceptibility for autism. To this end, 267 subjects with autism spectrum disorder and 617 controls were genotyped for three polymorphisms in exon 1 of the AR gene: the CAG repeat, the GGN repeat and the rs6152 SNP. In addition, parents and affected siblings were genotyped for 118 and 32 of the cases, respectively. Case-control comparisons revealed higher prevalence of short CAG alleles as well as of the A allele of the rs6152 SNP in female cases than in controls, but revealed no significant differences with respect to the GGN repeat. Analysis of the 118 families using transmission disequilibrium test, on the other hand, suggested an association with the GGN polymorphism, the rare 20-repeat allele being undertransmitted to male cases and the 23-repeat allele being overtransmitted to female cases. Sequencing of the AR gene in 46 patients revealed no mutations or rare variants. The results lend some support for an influence of the studied polymorphisms on the susceptibility for autism, but argue against the possibility that mutations in the AR gene are common in subjects with this condition.

- Although genetic factors are known to be important risk factors for panic disorder there is as yet no conclusive data regarding specific gene variants. Prompted by evidence supporting progesterone to influence the pathophysiology of panic disorder, polymorphisms in the progesterone receptor gene, a single nucleotide polymorphism (G331A) and an insertion/deletion polymorphism (PROGINS) were investigated in 72 patients with panic disorder and 452 controls. The frequency of the A-allele of the G331A polymorphism was higher in panic disorder patients than in controls (p = 0.01). When male and female patients were analyzed separately, the association was observed in female patients only (p = 0.0009), with an odds ratio of 3.5. No differences between groups were observed for the PROGINS polymorphism. In conclusion, these data suggest that the G331A polymorphism in the progesterone receptor gene may influence the risk for panic disorder in women.

- The aggressive behavior displayed by some (but not all) female Wistar rats when an unfamiliar rat is being introduced into their home cage (the resident intruder paradigm) was found to be higher in non-receptive phases (metestrus, diestrus) than in the receptive phases (proestrus, estrus) of the estrus cycle, and effectively reduced by ovariectomy. When removal of the ovaries was followed by administration of estradiol and progesterone, in a regimen mimicking the normal cyclical release of these hormones, aggressive behavior was elicited, two days after estrus, in animals that had displayed aggressive behavior before ovariectomy, but not in those that had not. Short-term administration of a serotonin reuptake inhibitor (fluoxetine hydrochloride; 10 mg/kg, i.p.; 4-5 days) reduced both the aggressive behavior displayed during the diestrus phase by normally cycling rats, and the aggressive behavior elicited by administration of estradiol plus progesterone after ovariectomy. It is suggested that the aggressive behavior displayed by the female Wistar rat in the resident intruder paradigm may serve as an animal model of premenstrual dysphoria.

- The quantitative genetic contribution to antisocial behavior is well established, but few, if any, genetic variants are established as risk factors. Emerging evidence suggests that the neuropeptide oxytocin (OXT) may modulate interpersonal aggression. We here investigated whether single-nucleotide polymorphisms (SNPs) in the OXT receptor gene (OXTR) are associated with the expression of antisocial behavior. A discovery sample, including both sexes, was drawn from the Child and Adolescent Twin Study in Sweden (CATSS; n=2372), and a sample from the Twin Study of Child and Adolescent Development (TCHAD; n=1232) was used for replication. Eight SNPs in OXTR, selected on previous associations with social and antisocial behavior, were genotyped in the participants of CATSS. Significant polymorphisms were subsequently genotyped in TCHAD for replication. Participants completed self-assessment questionnaires-Life History of Aggression (LHA; available only in CATSS), and Self-Reported Delinquency (SRD; available in both samples)-designed to capture antisocial behavior as continuous traits. In the discovery sample, the rs7632287 AA genotype was associated with higher frequency of antisocial behavior in boys, and this was then replicated in the second sample. In particular, overt aggression (directly targeting another individual) was strongly associated with this genotype in boys (P=6.2 × 10(-7) in the discovery sample). Meta-analysis of the results for antisocial behavior from both samples yielded P=2.5 × 10(-5). Furthermore, an association between rs4564970 and LHA (P=0.00013) survived correction in the discovery sample, but there was no association with the SRD in the replication sample. We conclude that the rs7632287 and rs4564970 polymorphisms in OXTR may independently influence antisocial behavior in adolescent boys. Further replication of our results will be crucial to understanding how aberrant social behavior arises, and would support the OXT receptor as one potential target in the treatment of aggressive antisocial behavior.Molecular Psychiatry advance online publication, 22 September 2015; doi:10.1038/mp.2015.144.
