Quality of life and sleep, depression, family functioning, and marital adjustment in patients on hemodialysis and peritoneal dialysis.

End-stage renal disease is different from other chronic diseases that the treatment method is as difficult. Our aim in this study was to compare marital adjustment, sexual functions and family functioning between hemodialysis (HD) and peritoneal dialysis (PD) patient. A total of 21 HD and 27 PD patients were included. Beck Depression Inventory (BDI), Short Form-36 (SF-36), Pittsburgh Sleep Quality Index (PSQI), Arizona Sexual Experiences Scale (ASEX), Golombok-Rust Inventory for Sexual Satisfaction (GRISS), Marital Adjustment Test (MAT) and Family Assessment Device (FAD) were applied. BDI scores were significantly higher in HD patients (p < 0.001). According to FAD problem solving (p < 0.001), communication (p = 0.00) and general functioning scores (p = 0.04) were higher in PD. The rate of poor sleep quality was 44.4% in the PD group, and 66.7% in HD group (p = 0.12). General health (p = 0.04), vitality (p < 0.001), mental health (p = 0.00) and social functioning (p = 0.00) scores were lower in HD patients. HD patients are at high risk for psychiatric disorders due to the treatment modality. These patients should be monitored carefully and consultation-liaison services should be increased.

Higher Risk of Psychiatric Disorders in Children With Febrile Seizures: A Nationwide Cohort Study in Taiwan

BackgroundFebrile seizures occur commonly in children aged between six months and six years. A previous Danish study found a positive correlation between febrile seizures and the overall incidence of psychiatric disorders. This population-based nationwide observational study was conducted to investigate the association between febrile seizures and different psychiatric disorders in Taiwan and the associated risk factors. MethodsThis cohort study used data from the National Health Insurance Research Database in Taiwan—a nationwide claims database covering >99% of the Taiwanese population. The study period was from January 2000 to December 2015; the overall median follow-up time was 11.04 ± 10.95 years. Overall, 2464 children with febrile seizures diagnosed between 2000 and 2015 met the inclusion criteria, and 7392 children without febrile seizures matched by index year, age, and sex were included in the control cohorts. Febrile seizures and psychiatric disorders were measured as the exposure and main outcomes, respectively. ResultsChildren with febrile seizures (n = 2463) were at a high risk of psychiatric disorders (adjusted hazard ratio, 4.70; 95% confidence interval [CI], 2.44 to 7.30; P < 0.001). The risk for anxiety was the highest (adjusted hazard ratio, 21.92; 95% CI, 11.40 to 34.05; P < 0.001). ConclusionsWhen treating children with febrile seizures, particular attention should be paid to the symptoms of psychiatric disorders, as early referral may be beneficial for these children.

Delay discounting and family history of psychopathology in children ages 9–11

Delay discounting is a tendency to devalue delayed rewards compared to immediate rewards. Evidence suggests that steeper delay discounting is associated with psychiatric disorders across diagnostic categories, but it is unclear whether steeper delay discounting is a risk factor for these disorders. We examined whether children at higher risk for psychiatric disorders, based on family history, would demonstrate steeper delay discounting behavior using data from the Adolescent Brain Cognitive Development (ABCD) study, a nationally representative sample of 11,878 children. We looked at associations between delay discounting behavior and family history of alcohol problems, drug problems, depression, mania, schizophrenia, and suicidal behavior. Correlations between family history of psychopathology and delay discounting behavior were small, ranging from ρ = − 0.02 to 0.04. In mixed effects models controlled for sociodemographic factors, family history of psychopathology was not associated with steeper delay discounting behavior. Sociodemographic factors played a larger role in predicting delay discounting behavior than family history of psychopathology. These results do not support the hypothesis that children with greater risk for psychopathology display steeper delay discounting behavior.

Sibling complexity and psychiatric disorders in late adolescence among the Finnish 2000 birth cohort

Abstract Background Due to the increasing family instability and multipartner fertility in Western countries, more children have half- and stepsiblings. While numerous studies link family instability and complexity with mental health problems, the focus has typically been on the parents while a small but growing literature suggest that sibling constellations with half- and stepsiblings may also be important for adolescent mental health. Methods This study is based on administrative register data of all children born in Finland in 2000 and residing there at ages 0 − 15 (n = 56,372). We identified the biological parents, their cohabiting partners, and any full, half and step siblings that the index child has from birth to age 15. We used Cox proportional-hazards models to compare differences in psychiatric disorders from age 16 to 19 for boys and girls by different sibling constellations. Psychiatric disorders were identified as any disorders treated in specialized outpatient or hospital care (n = 7,999). Results Almost one in five children in the birth cohort had a cohabiting half sibling and almost 4% had a step sibling. Psychiatric disorders in late adolescence were more prevalent among children in different sibling compositions with half or step siblings. For example, the preliminary results show that adjusting for confounders such as socioeconomic status and living with both biological parents or not, boys and girls with an older half sibling had a 44% (95% confidence interval 34-55) higher risk of psychiatric disorders when compared to children with biological siblings only. The corresponding difference in risk for those with younger half siblings was 24% (11-55). Conclusions Psychiatric disorders were more prevalent in late adolescence among children with half and/or step siblings. Future studies on family complexity are likely to benefit from including information on sibling characteristics in addition to those of the parents. Key messages • Adolescents growing up with half or stepsiblings had a higher prevalence of psychiatric disorders in late adolescence. • More studies on sibling composition and adolescent psychiatric disorders are needed to inform the type of supportive measures that may benefit children living with half and stepsiblings.

The relations between chronotype, stressful life events, and impulsivity in the Adolescent Brain Cognitive Development (ABCD) study

Circadian rhythm disturbances, especially circadian phase delays are associated with impulsive behaviors and have been implicated in psychiatric disorders. Chronotype is a developmentally regulated proxy measure of circadian phase. Past studies have investigated the relationship between chronotype and trauma and found that trauma is associated with evening chronotypes, suggesting the course of chronotype development may be affected by adverse childhood experiences (ACEs). However, the relationships among chronotype, impulsivity and ACEs have largely been studied in a pairwise manner using small, cross-sectional cohorts. We hypothesized that in a cohort of high-risk youth, childhood trauma would be associated with later chronotype, and later chronotype would be associated with higher rates of impulsivity. We analyzed a cross-sectional sample (n = 966) from Year 2 of adolescents at high risk for psychiatric disorders from the ABCD study who were characterized for chronotype, stressful life events, and impulsivity. We used a hierarchical regression model to examine the relationship between chronotype, stressful life events, and impulsivity using the Munich Chronotype Questionnaire (MCTQ), the Life Events Scale, Urgency, Premeditation, Perseverance and Sensation Seeking (UPPS) Impulsive Behavior scale. We found associations between eveningness, stressful life events, and all dimensions of impulsivity. Increased eveningness was associated with a higher number of stressful life events and increased impulsivity. Understanding the role of stressful life events and impulsivity in those predisposed towards eveningness is useful because it may improve our understanding of the biological mechanisms that contribute to psychiatric disorders, and lead to better prevention and treatment efforts using interventions such as increased lifestyle regularity and daytime light exposure.

Helper Syndrome and Pathological Altruism in nurses - a study in times of the COVID-19 pandemic.

Pathological Altruism and the concept of Helper Syndrome are comparable. We focused on Schmidbauer's description because it provides a comprehensive and testable definition. Nevertheless, this concept of Helper Syndrome has not yet been empirically investigated in a sample of helping professionals. To investigate whether nurses working with covid-19 patients are more likely to have Helper Syndrome compared with individuals from non-helper professions. The online survey took place between April 2021 and February 2022, in urban and rural regions of Salzburg, during the time of the COVID-19 pandemic. Nurses (n = 447) and controls (n = 295) were compared regarding Helper Syndrome characteristics. To measure characteristics of Helper Syndrome the following questionnaires were used: WHO-Five (WHO-5), selected scales of the Personality, Style and Disorder Inventory (PSSI) and the Freiburg Personality Inventory-Revised (FPI-R), the Alcohol Use Disorders Identification Test (AUDIT). Insecure gender identity and self-assessment of having a Helper Syndrome was measured by a Likert scale. In both groups, Helper Syndrome was detected (nurses 29.5%, controls 30.5%). Participants with Helper Syndrome showed significant differences in personality styles and traits, namely significantly higher scores for Foreboding-Schizotypical Personality Style, Spontaneous-Borderline Personality Style, Amiable-Histrionic Personality Style, Ambitious-Narcissistic Personality Style, Loyal-Dependent Personality Style, Helpful-Selfless Personality Style, Carefully-Obsessive Personality Style, Optimistic-Rhapsodic Personality Style, Social Orientation, Strain, Emotionality and lower well-being. The only difference between nurses and controls was that nurses were significantly less open aggressive. For the first time, we were able to demonstrate Schmidbauer's concept of Helper Syndrome. According to our data, we found a subgroup of individuals similar to Schmidbauer's description of Helper Syndrome, but this sample was independent of helping or non-helping profession. These individuals seem to be at higher risk for psychiatric disorders.

DiGeorge Syndrome With Atypical Psychotic Symptoms: The Need for a Multidisciplinary Methodology

DiGeorge syndrome (DGS), known as 22q11.2 deletion syndrome or velocardiofacial syndrome, is one of the most common microdeletion syndromes in humans. Developmental delay, intellectual disability, congenital cardiac and gross vessel anomalies, hypocalcemia, and hearing loss may be seen and characterized by dysmorphic facial features. The syndrome has high risk for psychiatric disorders, specifically intellectual disability and psychotic disorders. Dysmorphic features may be overlooked and the diagnosis may be delayed for years. We explore a case of DGS with intellectual disability and atypical psychotic symptoms. A 19-year-old female patient had atypical psychotic symptoms, dysmorphic facial features, and unilateral hearing loss. Intellectual disability was detected in the IQ test evaluation. A detailed investigation and genetic evaluation resulted in a diagnosis of DGS. This case report highlights the variable clinical presentation of DGS in each patient and the need for a multidisciplinary methodology to diagnose and treat it.

Prevalence of psychiatric morbidity among school-going adolescents in the age group of 13–19 years

BackgroundAdolescent mental health problems are vast and varied and early identification and intervention can be of utmost help. There is sparse data on mental health issues in the adolescent population from India in general and J&K in particular; thus, it was decided to embark on this study.ResultsThe prevalence of various psychiatric disorders among school-going adolescents was as major depressive disorder 13.7%, obsessive compulsive disorder 4.0%, panic disorder 1.4%, self-harming behavior 2.5%, generalized anxiety disorder 2.5%, social anxiety disorder 2.2%, dysthymia 1.7%, and adjustment disorder 0.8%. There was no statistically significant difference in the overall psychiatric morbidity group among males and females (P = 0.90). However, panic disorder and borderline personality disorder as a group were more commonly found among females compared to males (P = 0.016 and 0.001 respectively). Also, 34% from urban and 28% from rural areas met the criteria for any psychiatric disorder (P = 1.38).ConclusionChildren and adolescents represent a tender part of the human life cycle and they may be at a higher risk of psychiatric disorders. There is a very high prevalence of psychiatric morbidity of any kind among adolescents in Kashmir, many of which are unidentified and thus untreated. Depression is the most common psychiatric illness among adolescents with a higher prevalence in males while anxiety disorders are more common among females. There is a need for further research in this age group and teachers and parents need psycho-education for the identification of such children.

Study Protocol: Adolescents of Ukraine During the Russian Invasion (AUDRI) Cohort

BackgroundSince February 14, 2022, Ukraine has once again been under attack by the Russian forces, putting the nation in one of the biggest emergencies in Europe since World War II. This puts Ukrainians at high risk of psychiatric disorders, amidst unseen attacks on infrastructure that have put massive strain on Ukraine’s mental health services. Despite this, the prevalence of psychiatric disorders among adolescents and their changes over time have not yet been documented in Ukraine during the invasion. More generally, there is a need to more comprehensively uncover the long-term consequences of war on youth, especially their risks and protective factors.MethodsThe Adolescents of Ukraine During the Russian Invasion (AUDRI) Cohort is the largest cohort of war-affected Ukrainian adolescents. We will recruit adolescents aged 15 to 18 years attending any school in Ukraine. Data collection will start early 2023, and will be held via online questionnaires every six months during the war as well as after the war has terminated. We will use several well-validated tools to screen for PTSD, depression, anxiety, substance use disorder, and eating disorders. In addition, we will ask participants about possible risks and protective factors of their mental health including resilience and social capital. Using the cohort, we will evaluate the trends in psychiatric disorder prevalence among adolescents in Ukraine over time and evaluate risks and protective factors of adolescents’ mental health.DiscussionThe AUDRI Cohort will provide a unique opportunity to learn more about trauma and resilience among youth in conflict settings, in addition to aiding international efforts to save the mental health of youth in Ukraine. At-risk adolescents identified from our study can directly become beneficiaries of targeted intervention themselves. Building evidence on the mental health of adolescents is especially valuable, as protecting the mental health of war-affected adolescents could help rebuild society and have positive consequences for generations to come.

A Population-Based Cohort Study of the Association between Visual Loss and Risk of Suicide and Mental Illness in Taiwan.

The psychosocial and health consequences of ocular conditions that cause visual impairment (VI) are extensive and include impaired daily activities, social isolation, cognitive impairment, impaired functional status and functional decline, increased reliance on others, increased risk of motor vehicle accidents, falls and fractures, poor self-rated health, and depression. We aimed to determine whether VI increases the likelihood of a poor prognosis, including mental illness, suicide, and mortality over time. In this large, location, population-based, nested, cohort study, we used data from 2000 to 2015 in the Taiwan National Health Insurance Research Database (NHIRD), which includes diagnoses of all the patients with VI. Baseline features, comorbidities, and prognostic variables were evaluated using a 1:4-matched cohort analysis. Furthermore, comparisons were performed using Cox regression and Bonferroni-correction (for multiple comparisons) to study the association between VI and poor prognosis (mental illness, suicide). The study outcome was the cumulative incidence of poor prognosis among the visually impaired and controls. A two-tailed Bonferroni-corrected p < 0.001 was considered statistically significant. Among the 1,949,101 patients enlisted in the NHIRD, 271 had been diagnosed with VI. Risk factors for poor prognosis and the crude hazard ratio was 3.004 (95% confidence interval 2.135-4.121, p < 0.001). Participants with VI had an increased risk of poor prognosis according to the sensitivity analysis, with a poor prognosis within the first year and first five years. VI was associated with suicide and mental health risks. This study revealed that patients with VI have a nearly 3-fold higher risk of psychiatric disorders, including anxiety, depression, bipolar, and sleep disorders, than the general population. Early detection through comprehensive examinations based on increased awareness in the clinical context may help maintain visual function and avoid additional complications.

Associations between parental psychiatric disorders and autism spectrum disorder in the offspring.

Whether parental psychiatric disorders are associated with autism spectrum disorder (ASD) in offspring has remained inconclusive. We examined the associations of parental psychiatric disorders with ASD in offspring. This population-based case-control study used Taiwan's National Health Insurance Research Database to identify a cohort of children born from 2004 to 2017 and their parents. A total of 24,279 children with ASD (diagnostic ICD-9-CM code: 299.x or ICD-10 code F84.x) and 97,715 matched controls were included. Parental psychiatric disorders, including depressive disorders, bipolar spectrum disorders, anxiety disorders, obsessive-compulsive disorder, schizophrenia, substance use disorders, autism spectrum disorder, attention-deficit hyperactivity disorder (ADHD), and adjustment disorders were identified. Conditional logistic regressions with covariate adjustment were performed. The results suggest that parental diagnosis with any of the psychiatric disorders is associated with ASD in offspring (adjusted odds ratio [AOR]=1.45, 95%CI: 1.40-1.51 for mothers; and AOR=1.12, 95%CI: 1.08-1.17 for fathers). ASD in offspring was associated with schizophrenia, depressive disorders, obsessive-compulsive disorder, adjustment disorders, ADHD and ASD in both parents. The relationship between parental psychiatric disorders and the timing of the child's birth and ASD diagnosis varied across the different psychiatric disorders. The present study provides supportive evidence that parental psychiatric disorders are associated with autistic children. Furthermore, because the associations between parental psychiatric disorders and the timing of child's birth and ASD diagnosis varied across psychiatric disorders, the observed relationships may be affected by both genetic and environmental factors. Future studies are needed to disentangle the potential influence of genetic and environmental factors on the observed associations.

Comorbidity Between Recent Diagnosis of Type 2 Diabetes and Non-Psychotic Psychiatric Disorders: Metabolic Characteristics and Clinical Correlates.

PurposeTo describe the metabolic status and clinical characteristics associated with NPPD in patients with less than five years of T2D diagnosis and explore the role of age in the presentation of psychiatric comorbidities.Patients and MethodsThis was a cross-sectional study of subjects who attended a comprehensive care program. Patients were assessed using the Mini-International Neuropsychiatric Interview, and clinical and metabolic characteristics were registered. Multivariate logistic regression analyses were conducted to identify risk and protective factors for psychiatric disorders. We performed an analysis to further explore age’s influence on our results.ResultsWe included 1953 patients, and 40.1% had any psychiatric disorder. Younger age, female sex, and personal psychiatric history were associated with NPPD. The use of insulin was reported as a protective factor for eating disorders. Body mass index was associated with any psychiatric disorders and eating disorders. The analysis of age reported that patients younger than 45 years had the worst metabolic parameters and increased odds for NPPD, while patients older than 65 years had the best metabolic measures and decreased odds for psychiatric comorbidity.ConclusionNPPD were frequent comorbidities in our sample; younger age, female sex, and personal psychiatric history were the most important factors associated with psychiatric comorbidities. Younger subjects experience a higher risk for psychiatric disorders and worst metabolic control.

Peer victimization and associated alcohol and substance use: Prospective pathways for negative outcomes

A considerable number of studies have documented associations between peer victimization and concurrent and prospective increase in alcohol and substance use. Only a handful have investigated the psychological (e.g., internalizing behavior) and biological (e.g., neural systems) factors that contribute to this relation. Emerging studies provide clues as to mechanisms that may underlie increased risk for alcohol and substance use and associated problems in peer victimized youth, which may serve as potential targets for intervention. This review proposes a conceptual framework of increased alcohol/substance use in peer victimized youth as sequelae of alterations in the structure and/or function of neural regions broadly implicated in cognitive control and emotion processing/regulation. Studies are outlined linking peer victimization with alcohol/substance use, associations with internalizing symptoms, and differential structure and function in, and connectivity among, neural regions implicated in alcohol/substance use disorders. Further, the role(s) of neuroendocrine dysfunction, comorbid mental illness, and genetics are discussed as risk factors for substance use following peer victimization. This review concludes with the identification of gaps in the literature and suggestions for further investigation, such as the need for more studies examining the neural correlates of peer victimization, including cyberbullying, and greater consistency in how peer victimization and alcohol/substance use are operationalized and measured across studies. Prospective investigations of biological and psychosocial factors that contribute to alcohol and substance use and development of alcohol/substance use problems are needed to inform novel intervention and prevention strategies in typically developing youth and in populations with high rates of peer victimization, such as individuals with comorbid mental illness and those at high risk for psychiatric disorders.

In Case You Haven't Heard…

Significant reductions in cigarette use were found among U.S. adults with major depression, substance use disorder or both from 2006 to 2019, according to a new analysis of nationally representative survey data published April 26 in the Journal of the American Medical Association. The study was conducted by researchers at the National Institute on Drug Abuse, part of the National Institutes of Health, and the Substance Abuse and Mental Health Services Administration. These findings suggest that groups at higher risk of cigarette smoking can be reached by, and may have benefited from, tobacco use prevention and cessation efforts that have led to significant declines in tobacco use in the general population. At the same time, the findings highlight remaining disparities, documenting higher smoking rates in people with psychiatric disorders than in those without. In future work, the researchers note the need to include data on certain populations at high risk of psychiatric disorders and cigarette smoking, such as institutionalized individuals or those experiencing homelessness without living in a shelter.

Exploring associations between diurnal cortisol, stress, coping and psychopathology in adolescents and young adults with 22q11.2 deletion syndrome

Background22q11.2 deletion syndrome (22q11DS) is a neurogenetic condition associated to a high risk for psychiatric disorders, including psychosis. Individuals with 22q11DS are thought to experience increased levels of chronic stress, which could lead to alterations in hypothalamic-pituitary-adrenocortical (HPA)-axis functioning. In the current study, we investigated for the first time diurnal salivary cortisol profiles in adolescents and young adults with 22q11DS as well as their link with stress exposure, coping strategies and psychopathology, including psychotic symptoms. MethodsSalivary cortisol was collected from adolescents and young adults with 22q11DS (n = 30, age = 19.7) and matched healthy controls (HC; n = 36, age = 18.5) six times a day for two days. Exposure to stressful life events, including peer victimization, coping strategies and general psychopathology were assessed with questionnaires. Psychotic symptoms and psychiatric comorbidities were evaluated with clinical interviews. ResultsWe observed similar daily levels and diurnal profiles of salivary cortisol in adolescents and young adults with 22q11DS compared to HCs. However, participants with 22q11DS reported less frequent exposure to stress than HCs. In 22q11DS, we observed a significant association between the use of non-adaptive coping strategies and the severity of psychotics symptoms. Cortisol level was not associated to severity of psychotic symptoms, but elevated cortisol awakening response (CAR) was found in participants with 22q11DS with higher levels of general psychopathology. ConclusionsOur results do not support earlier propositions of altered HPA-axis functioning in 22q11DS but highlight the need to further investigate diurnal cortisol as an indicator of HPA-axis functioning and its link with (earlier) stress exposure and psychopathology in this population. Interventions should target the development of adaptive coping skills in preventing psychosis in 22q11DS.

Psychiatric disorders in childhood cancer survivors in Denmark, Finland, and Sweden: a register-based cohort study from the SALiCCS research programme

A childhood cancer diagnosis and treatment-induced somatic late effects can affect the long-term mental health of survivors. We aimed to explore whether childhood cancer survivors are at higher risk of psychiatric disorders later in life than their siblings and the general population. In this register-based cohort study (part of the Socioeconomic Consequences in Adult Life after Childhood Cancer [SALiCCS] research programme), we included 5-year survivors of childhood cancer diagnosed before 20 years of age between Jan 1, 1974 and Dec 31, 2011, in Denmark, Finland, and Sweden. In Denmark and Sweden, 94·7% of individuals were born in a Nordic country (ie, Denmark, Finland, Iceland, Norway, or Sweden); similar information was not available in Finland. Data on ethnicity were not collected. Survivors were compared with their siblings and randomly selected individuals from the general population who were matched to the survivors by year of birth, sex, and geographical region. We followed up our study population from 5 years after the childhood cancer diagnosis or corresponding calendar date for matched individuals (the index date) until Aug 11, 2017, and assessed information on hospital contacts for any and specific psychiatric disorders. For siblings, the index date was defined as 5 years from the date on which they were of the same age as their sibling survivor when diagnosed with cancer. The study population included 18 621 childhood cancer survivors (9934 [53·3%] males and 8687 [46·7%] females), 24 775 siblings (12 594 [50·8%] males and 12 181 [49·2%] females), and 88 630 matched individuals (47 300 [53·4%] males and 41 330 [46·6%] females). The cumulative incidence proportion of having had a psychiatric hospital contact by 30 years of age between Jan 1, 1979, and Aug 11, 2017, was 15·9% (95% CI 15·3-16·5) for childhood cancer survivors, 14·0% (13·5-14·5) for siblings, and 12·7% (12·4-12·9) for matched individuals. Despite a small absolute difference, survivors were at higher relative risk of any psychiatric hospital contact than their siblings (1·39, 1·31-1·48) and matched individuals (hazard ratio 1·34, 95% CI 1·28-1·39). The higher risk persisted at the age of 50 years. Survivors had a higher burden of recurrent psychiatric hospital contacts and had more hospital contacts for different psychiatric disorders than their siblings and the matched individuals. Childhood cancer survivors are at higher long-term risk of psychiatric disorders than their siblings and matched individuals from the general population. To improve mental health and the overall quality of life after childhood cancer, survivorship care should include a focus on early signs of mental health problems, especially among high-risk groups of survivors.

High risk for psychiatric disorders in bipolar offspring. A four years prospective study

Bipolar disorder (BD) has a large hereditary component. It is a disorder that begins in early adulthood, but about which it has been described a premorbid period preceding the onset of BD. During this herald expression psychiatric disorders and symptoms, such as depressive, manic, psychotic, anxious and others, may appear. ObjectiveTo determine the psychopathological profile of a Bipolar Offspring (BO) group compared with the Community Control Offspring (CCO) group, and its evolution over time, including subthreshold symptoms and mental disorders. MethodsWe conducted an observational mixed cohort study, with a prospective design. We included subjects from six to 30 years of age, from the region of Antioquia, Colombia. A total of 131 subjects from the risk group BO and 150 subjects from the CCO group were evaluated through validated psychiatric diagnostic interviews (K-SADS-PL and DIGS) at baseline and at 4 years follow up. All interviews were carried out by a staff blind to parent diagnoses. Follow-up assessment were complete in 72% of the offspring. Forty-two subjects were excluded as they surpassed the age of 30 years, and only 46 subjects were not followed (change of address or did not consent to participate). ResultsCompared with the CCO group, the BO group had a higher frequency of affective disorder, psychotic disorder, externalizing disorders and use of the psychoactive substances during both assessments at time 1 and 2. The magnitude of the differences between the groups increased when they reach time 2. The BO group had a greater risk for presenting subthreshold symptoms and definitive psychiatric disorders, such as affective disorders, psychotic disorders and externalizing disorders. In addition, the BO group had a younger age of onset for psychoactive substances consumption. ConclusionDuring the follow-up period, the BO group had a higher risk of presenting mental disorders compared with the CCO group. The most relevant symptoms and disorders that could precede the onset of BD were depressive, bipolar not otherwise specified, psychotic and substance use.

Medial prefrontal area reductions, altered expressions of cholecystokinin, parvalbumin, and activating transcription factor 4 in the corticolimbic system, and altered emotional behavior in a progressive rat model of type 2 diabetes.

Metabolic disorders are associated with a higher risk of psychiatric disorders. We previously reported that 20-week-old Otsuka Long-Evans Tokushima fatty (OLETF) rats, a model of progressive type 2 diabetes, showed increased anxiety-like behavior and regional area reductions and increased cholecystokinin-positive neurons in the corticolimbic system. However, in which stages of diabetes these alterations in OLETF rats occur remains unclear. We aimed to investigate anxiety-like behavior and its possible mechanisms at different stages of type 2 diabetes in OLETF rats. Eight- and 30-week-old OLETF rats were used as diabetic animal models at the prediabetic and progressive stages of type 2 diabetes respectively, and age-matched Long-Evans Tokushima Otsuka rats served as non-diabetic controls. In the open-field test, OLETF rats showed less locomotion in the center zone and longer latency to leave the center zone at 8 and 30 weeks old, respectively. The areas of the medial prefrontal cortex were smaller in the OLETF rats, regardless of age. The densities of cholecystokinin-positive neurons in OLETF rats were higher in the lateral and basolateral amygdala only at 8 weeks old and in the anterior cingulate and infralimbic cortices and hippocampal cornu ammonis area 3 at both ages. The densities of parvalbumin-positive neurons of OLETF rats were lower in the cornu ammonis area 2 at 8 weeks old and in the prelimbic and infralimbic cortices at both ages. No apoptotic cell death was detected in OLETF rats, but the percentage of neurons co-expressing activating transcription factor 4 and cholecystokinin and parvalbumin was higher in OLETF rats at both ages in the anterior cingulate cortex and basolateral amygdala, respectively. These results suggest that altered emotional behavior and related neurological changes in the corticolimbic system are already present in the prediabetic stage of OLETF rats.

Association Between Tetralogy of Fallot and Psychiatric Disorders: A Nationwide Cohort Study.

The tetralogy of Fallot (TOF) has been reported to be associated with some neurodevelopmental impairment and psychiatric disorders. Nevertheless, a nationwide study to clarify the risk between TOF and comorbid psychiatric disorders is lacking. Using a nationwide database in Taiwan, this study aimed to explore the role of TOF in various psychiatric disorders and analyze whether there are patient-related risk factors. A total of 16,824 enrolled patients, including 4,206 study subjects who were diagnosed with TOF and 12,618 controls with TOF matched (1:3) for sex, age, hospital visits, and index year, were randomly selected from the Taiwanese National Health Insurance Research Database (NHIRD) between 2000 and 2015. Patients' diagnoses in the NHIRD were encoded using International Classification of Diseases, 9th Revision, Clinical Modification codes. Of patients with TOF, 256 (6.09%) developed psychiatric disorders compared to 394 (3.12%) in the control group. After adjusting for covariates, the adjusted hazard ratio of psychiatric disorders for patients with TOF was 3.192 (95% CI, 2.683-3.798; P < .001). After exclusion of psychiatric diagnoses within the first 5 years, TOF was associated with an increased risk of anxiety (P < .001), depression (P < .001), bipolar disorder (P < .001), and sleep disorders (P = .005). This study revealed that TOF patients have a nearly 3-fold higher risk of psychiatric disorders, including anxiety, depressive, bipolar, and sleep disorders, than the general population. Therefore, continued mental health screening and surveillance are warranted in TOF patients.
