Congenital hypothyroidism and risk of subsequent autism spectrum disorder and attention-deficit/hyperactivity disorder in Taiwan.

Aim: Evidence suggests an association between maternal hypothyroidism and risk of attention-deficit/hyperactivity disorder (ADHD) or autism spectrum disorder (ASD) in offspring. We examined the risk of ASD and ADHD in individuals with congenital hypothyroidism (CHT).

Methods: A nationwide population-based cohort study enrolled a total of 1260 children younger than 12 years with a confirmed diagnosis of CHT and no prior diagnosis of any neurodevelopmental disorders, selected from the National Health Insurance Research Database of Taiwan between 1998 to 2013.

Risk of Periodontitis in Adolescents With Attention Deficit Hyperactivity Disorder: A Cohort Study of 81,055 Participants.

Objectives: Previous studies have demonstrated poor oral hygiene in children with attention deficit hyperactivity disorder (ADHD). However, the association between ADHD and periodontitis is still unclear.

Methods: In all, 16,211 adolescents with ADHD and 162,110 age- and sex-matched controls participated in the study between 2001 and 2011.

Sexually transmitted infection and teenage pregnancy in adolescents having parents with schizophrenia: a retrospective cohort study of 64,350 participants.

Background: The risks of sexually transmitted infections (STIs) and teenage pregnancy in the offspring of parents with schizophrenia remain unknown.

Methods: From the Taiwan National Health Insurance Research Database, 5,850 individuals born between 1980 and 1999 having any parent with schizophrenia and 58,500 age-, sex-, income- and residence-matched controls without parents with severe mental disorders were enrolled in 1996 or on their birthdate and followed up to the end of 2011. Those who contracted any STI or became pregnant in adolescence during the follow-up period were identified.

Risk of traumatic brain injury among patients with ADHD and their unaffected siblings.

Background: As the relationship between attention deficit hyperactivity disorder (ADHD) and traumatic brain injury (TBI) is gaining increasing attention, the TBI risk in patients with ADHD, unaffected siblings of ADHD probands, and non-ADHD controls remains unclear.

Methods: Overall, 18,645 patients with ADHD, 18,880 unaffected siblings of ADHD probands, and 188,800 age-/sex-matched controls were followed up from enrollment to the end of 2011. The cases of TBI and TBI requiring hospitalization were identified during follow-up.

Dysfunction of circulating endothelial progenitor cells in major depressive disorder.

Objectives: Despite mounting evidence demonstrates circulating endothelial progenitor cells (cEPCs) quantitative changes in depression, no study has investigated cEPC functions in major depressive disorder (MDD). We investigated the role of cEPC adhesive and apoptotic functions in MDD.

Methods: We recruited 68 patients with MDD and 56 healthy controls (HCs).

Congenital cleft lip and palate and elevated risks of major psychiatric disorders: A nationwide longitudinal study.

Background: Congenital cleft lip and palate (CCLP) may be associated with major psychiatric disorders, including autism spectrum disorder (ASD), attention deficit hyperactivity disorder (ADHD), schizophrenia, bipolar disorder, and major depressive disorder.

Methods: From the Taiwan National Health Insurance Research Database, 1,158 children and adolescents with CCLP and 11,580 age/sex-matched controls without CCLP were included in this study between 2001 and 2010; they were followed up until the end of 2011 to identify the aforementioned major psychiatric disorders.

Results: After adjustment for age, sex, income, residence, and family history, the Cox regression model revealed a positive relationship of CCLP with subsequent schizophrenia (hazard ratio [HR]: 7.

Risk of periodontitis in adolescents with bipolar disorder: a cohort study of 21,255 subjects.

Although a growing number of studies have investigated the relationship between psychosocial factors and periodontitis, studies investigating the association between bipolar disorder (BD) and periodontitis are lacking. Using the Taiwan National Health Insurance Research Database, 4251 adolescents with BD and 17,004 age- and sex-matched controls were included. They were followed up from enrollment to the end of 2011 or death.

Disease progression to bipolar disorder among adolescents and young adults with antidepressant-resistant and antidepressant-responsive depression: Does antidepressant class matter?

Studies have demonstrated a positive relationship between antidepressant resistance and the progression of bipolar disorder. However, the influence of antidepressant classes such as selective serotonin reuptake inhibitors (SSRIs) and serotonin norepinephrine reuptake inhibitors (SNRIs) in this context has yet to be investigated. A total of 5,285 adolescents and young adults with antidepressant-resistant depression and 21,140 with antidepressant-responsive depression were recruited in the present study.

Appetite hormone dysregulation and executive dysfunction among adolescents with bipolar disorder and disruptive mood dysregulation disorder.

Appetite hormone dysregulation may play a role in the pathomechanisms of bipolar disorder and chronic irritability. However, its association with executive dysfunction in adolescents with bipolar disorder and those with disruptive mood dysregulation disorder (DMDD) remains unclear. We included 20 adolescents with bipolar disorder, 20 adolescents with DMDD, and 47 healthy controls.

Autism spectrum disorder and periodontitis risk: A cohort study of 38,203 adolescents.

Background: People with autism spectrum disorder (ASD) may have poor oral health status because they often experience challenges with daily oral hygiene and have inadequate access to oral health care services. This study explored periodontitis risk in adolescents with ASD compared with those who did not have a diagnosis of ASD.

Methods: Data from 2001 through December 31, 2011 from the Taiwan National Health Insurance Research Database on 3,473 adolescents with ASD and 34,730 age- and sex-matched people who did not have a diagnosis of ASD were obtained, and subsequent periodontitis was identified from enrollment through December 31, 2011.

Risk of Prescription Opioid Exposure in Children and Adolescents With Attention Deficit Hyperactivity Disorder: A Nationwide Longitudinal Study.

Background: US studies suggest a positive association between attention deficit-hyperactivity disorder (ADHD) and the risk of exposure to prescription opioids. However, whether this association holds in Asian countries remains unclear.

Methods: In total, 91,518 children and adolescents with ADHD and 91,518 age- and sex-matched controls were enrolled for the period of 2001 to 2009; they were followed up until the end of 2011 to determine whether they had used prescription opioids.

Longitudinal follow-up of subsequent psychiatric comorbidities among children and adolescents with autism spectrum disorder.

Background: The mental health of children and adolescents with autism spectrum disorder (ASD) is a concern of recent years. However, a large-scale longitudinal study investigating the risk and the time course of subsequent psychiatric comorbidities is still lacking.

Methods: Using the Taiwan National Health Insurance Research Database, 13,382 children and adolescents with ASD, and 53,528 age- and sex-matched non-ASD controls were enrolled between 2001 and 2009, and followed to the end of 2011.

Appetite hormone dysregulation, body mass index, and emotional dysregulation in nonobese adolescents with first-episode schizophrenia, bipolar disorder, and major depressive disorder: a cross-sectional association study.

Background: Evidence has suggested that emotional dysregulation is a transdiagnostic feature in schizophrenia and major affective disorders. However, the relationship between emotional dysregulation and appetite hormone disturbance remains unknown in nonobese adolescents with first-episode schizophrenia, bipolar disorder, and major depressive disorder.

Methods: In total, 22 adolescents with schizophrenia; 31 with bipolar disorder; 33 with major depressive disorder; and 41 healthy age-, sex-, and body mass index (BMI)/BMI percentile-matched controls were enrolled for assessing levels of appetite hormones, namely leptin, ghrelin, insulin, and adiponectin.

Antidepressant drugs use and epilepsy risk: A nationwide nested case-control study.

Background: To investigate the association between exposure to antidepressants (ADs) and the risk of epilepsy among patients exposed to ADs.

Method: We conducted a case-control study using Taiwan's National Health Insurance Research Database between 1998 and 2013. A total of 863 patients with epilepsy and 3,452 controls were included.

Risk of parental psychiatric disorders among adolescents with major depressive disorder according to response to antidepressant treatment: does the type of antidepressant matter?

Background: The genetic load for major depressive disorder (MDD) may be higher in people who develop MDD earlier in life. This study aimed to investigate whether the parents of adolescents with MDD were more likely to have MDD, bipolar disorder (BD), schizophrenic disorder (SZ), alcohol use disorder, or substance use disorder than the parents of adolescents without MDD. We also examined whether the response to antidepressant treatment predicted the likelihood of parental psychiatric disorders.
