Abstract
AIMS This study examined the incidence of attention-deficit/hyperactivity disorder medication among children and adolescents by sex and age group in Finland during 2008-2019. METHODS The data on children and adolescents aged 6-18 years receiving reimbursement for any attention-deficit/hyperactivity disorder medication was collected from the nationwide register on reimbursed purchases. The incidence was calculated as a ratio of the number of new users and the number of age and sex-matched population at risk. Negative binomial models were used to calculate rate ratios (RRs). RESULTS In 2019, the incidence of attention-deficit/hyperactivity disorder medication was 13.4 per 1000 boys and 4.8 per 1000 girls. Among boys, the incidence became 3.7 times greater during the observed years (RR 95% confidence interval (CI) 2.0, 6.5, P<0.0001), whereas in girls it was 7.6 times greater (RR 95% CI 2.1, 27.4, P=0.0019). The boys had 2.8 times the incidence rate compared with the girls (RR 95% CI 2.2, 3.6, P<0.0001). The increase was associated with age only among boys (P=0.0001). The highest incidence rate 23.4 per 1000 individuals (95% CI 22.5, 24.4) was found in 2019 among 6-8-year-old boys. CONCLUSIONS The incidence of attention-deficit/hyperactivity disorder medication use among children and adolescents increased significantly in Finland during the study period. Incidence was higher among boys, but the increase was greater among girls. The most common group to start attention-deficit/hyperactivity disorder medication was 6-8-year-old boys. These findings warrant critical evaluation of the diagnostic and treatment policies currently available in Finland for the treatment of attention-deficit/hyperactivity disorder and related symptoms.

Abstract
BACKGROUND Externalizing symptoms are associated with risk of future substance use disorder (SUD). Few longitudinal studies exist using general population-based samples which assess the spectrum of attention deficit hyperactivity disorder (ADHD) and oppositional defiant disorder (ODD) symptoms. AIMS/OBJECTIVES We aimed to study the associations between adolescent ADHD symptoms and subsequent SUD and additionally examine whether the risk of SUD is influenced by comorbid oppositional defiant disorder (ODD) symptoms. METHODS The Northern Finland Birth Cohort 1986 was linked to nationwide health care register data for incident SUD diagnoses until age 33 years (n = 6278, 49.5% male). ADHD/ODD-case status at age 16 years was defined using parent-rated ADHD indicated by Strengths and Weaknesses of ADHD symptoms and Normal Behaviors (SWAN) questionnaire with 95% percentile cut-off. To assess the impact of ODD comorbidity on SUD risk, participants were categorized into four groups based on their ADHD/ODD case status. Cox-regression analysis with hazard ratios (HRs) and 95% confidence intervals (CIs) were used to study associations between adolescent ADHD/ODD case statuses and subsequent SUD. RESULTS In all, 552 participants (8.8%) presented with ADHD case status at the age of 16 years, and 154/6278 (2.5%) were diagnosed with SUD during the follow-up. ADHD case status was associated with SUD during the follow-up (HR = 3.84, 95% CI 2.69-5.50). After adjustments for sex, family structure, and parental psychiatric disorder and early substance use the association with ADHD case status and SUD remained statistically significant (HR = 2.60, 95% CI 1.70-3.98). The risk of SUD remained elevated in individuals with ADHD case status irrespective of ODD symptoms. CONCLUSIONS ADHD in adolescence was associated with incident SUD in those with and without symptoms of ODD. The association of ADHD and SUD persisted even after adjustment for a wide range of potential confounds. This emphasizes the need to identify preventative strategies for adolescents with ADHD so as to improve health outcomes.

Abstract
BACKGROUND Diagnosis of attention deficit hyperactive disorder (ADHD) has been associated with increased risk of mortality in large register samples. However, there is less known about the association between symptoms of ADHD in adolescents and risk of mortality in general population samples. METHODS The Northern Finland Birth Cohort 1986 (n = 9432 at recruitment in early pregnancy) linked to nationwide register data for deaths was utilized to study the association between parent-rated ADHD symptoms assessed using Strengths and Weaknesses of ADHD symptoms and Normal Behaviors (SWAN) questionnaire and mortality until age 33 years. Cox-regression analysis with hazard ratios (HRs) and 95% confidence intervals (CIs) was used to study the association between SWAN inattentive, hyperactive, and combined symptom scores and risk of death. RESULTS Sixty-three (0.9%) of the 6685 participants died during the follow-up. Higher SWAN inattentive (crude HR = 2.30, 95% CI 1.46-3.63), SWAN hyperactive (crude HR = 2.43, 95% CI 1.29-4.56), and SWAN combined (crude HR = 2.69, 95% CI 1.57-4.61) scores were associated with increased risk of death. After adjustments for sex, family structure, and lifetime parental psychiatric disorder, these associations persisted. Further adjustment for frequent alcohol intoxication, cannabis, and other substance use in adolescence attenuated these to below statistical significance. CONCLUSIONS These results extend previous findings on the risk of mortality in adolescents who have symptoms of ADHD. Further research with larger samples are needed to determine whether the association between ADHD symptoms and mortality is independent of adolescent substance use.

Abstract
Aim: Prevalence studies on gambling have largely relied on survey samples. Little is known about the diagnosed prevalence of gambling disorder (GD) based on register data. This study examines the annual prevalence rate of GD between 2011 and 2020 among Finns by gender and age. Methods: Aggregated data on the diagnosis of GD (corresponding to pathological gambling, code F63.0 in the ICD-10) were retrieved from the following national registers: Register of Primary Health Care Visits, and Care Register for Health Care, including specialised outpatient and inpatient health care, and inpatient Care Register for Social Welfare. Primary and secondary diagnoses of adults were included. Average population during a calendar year (4,282,714–4,460,177 individuals) was utilised to calculate annual prevalence. Results: The annual prevalence of diagnosed GD in the population increased from 0.005% ( n = 196) to 0.018% ( n = 804) within nine years. In 2011, the annual prevalence rate was 0.006% for men and 0.003% for women, compared to rates in 2020 of 0.025% and 0.011%. Gender discrepancy was relatively stable across years: 27.2–33.8% of the diagnoses were for women. The prevalence of GD varied between age groups within genders. GD was most prevalent among 18–44-year-olds. The prevalence rates increased the most among 30–44-year-old women. Conclusion: The extremely low prevalence rate of GD implies that the problem remains under-diagnosed, yet, it has increased among all age groups across genders, except for women aged 60 years or older. Active efforts are needed to increase awareness of GD among both primary and specialised healthcare professionals and the public for better recognition and early detection.

Abstract
BACKGROUND Studies have shown a high prevalence of depression during pregnancy, and there is also evidence that cognitive behavioral therapy (CBT) is one of the most effective psychosocial interventions. Emerging evidence from randomized controlled trials (RCTs) has shown that technology has been successfully harnessed to provide CBT interventions for other populations. However, very few studies have focused on their use during pregnancy. This approach has become increasingly important in many clinical areas due to the COVID-19 pandemic, and our study aimed to expand the knowledge in this particular clinical area. OBJECTIVE Our systematic review aimed to bring together the available research-based evidence on digitalized CBT interventions for depression symptoms during pregnancy. METHODS A systematic review of the Web of Science, Cochrane Central Register of Controlled Trials, CINAHL, MEDLINE, Embase, PsycINFO, Scopus, ClinicalTrials.gov, and EBSCO Open Dissertations databases was carried out from the earliest available evidence to October 27, 2021. Only RCT studies published in English were considered. The PRISMA (Preferred Reporting Items of Systematic Reviews and Meta-analyses) guidelines were followed, and the protocol was registered on the Prospective Register of Systematic Reviews. The risk of bias was assessed using the revised Cochrane risk-of-bias tool for randomized trials. RESULTS The review identified 7 studies from 5 countries (the United States, China, Australia, Norway, and Sweden) published from 2015 to 2021. The sample sizes ranged from 25 to 1342 participants. The interventions used various technological elements, including text, images, videos, games, interactive features, and peer group discussions. They comprised 2 guided and 5 unguided approaches. Using digitalized CBT interventions for depression during pregnancy showed promising efficacy, with guided intervention showing higher effect sizes (Hedges g=1.21) than the unguided interventions (Hedges g=0.14-0.99). The acceptability of the digitalized CBT interventions was highly encouraging, based on user feedback. Attrition rates were low for the guided intervention (4.5%) but high for the unguided interventions (22.1%-46.5%). A high overall risk of bias was present for 6 of the 7 studies. CONCLUSIONS Our search only identified a small number of digitalized CBT interventions for pregnant women, despite the potential of this approach. These showed promising evidence when it came to efficacy and positive outcomes for depression symptoms, and user feedback was positive. However, the overall risk of bias suggests that the efficacy of the interventions needs to be interpreted with caution. Future studies need to consider how to mitigate these sources of biases. Digitalized CBT interventions can provide prompt, effective, evidence-based interventions for pregnant women. This review increases our understanding of the importance of digitalized interventions during pregnancy, including during the COVID-19 pandemic.

Abstract
Objective: The youngest children in a classroom have a higher risk of attention-deficit/hyperactivity disorders (ADHDs) and depression than their relatively older peers. However, there has been a lack of research on how relative age is related to second-generation antipsychotic (SGA) medication use. Methods: This study used the Finnish National Prescription Register data and comprised all 669,726 Finnish children and adolescents aged 7-17 in 2018. We extracted data for those who were dispensed SGAs (risperidone, quetiapine, aripiprazole, and olanzapine) and ADHD medication (methylphenidate, atomoxetine, dexamphetamine, and lisdexamfetamine). Odds ratios (OR) and 95% confidence intervals (CI) were calculated for medication dispensed to schoolchildren born from January to April (the relatively oldest), May to August, and September to December (the relatively youngest). Dispensed prescriptions were a proxy for medication use. Results: SGAs were dispensed to 9146 (1.4%) individuals in 2018. Their use was lower among girls aged 12-17 years born from September to December than January to April (OR 0.89; 95% CI 0.83-0.97), with no association between SGA use and birth month among boys. However, younger relative age was associated with combined SGA and ADHD medication, which was used by 2556 (0.4%) of the cohort: 2074 (0.6%) boys and 482 (0.1%) girls. The OR was 1.27 for boys aged 12-17 born from September to December (95% CI 1.10-1.46), compared with January to April. The OR for girls born from May to August was 1.35 (95% CI 1.04-1.76) and from September to December it was 1.33 (95% CI 1.02-1.74), compared with January to April. Conclusions: A novel discovery of this study was that using both SGA and ADHD medication at the age of 12-17 years was more common among the youngest subjects in a school year than their relatively older peers.

Abstract
Inpatient treatment is an important part of child and adolescent psychiatric (CAP) care. This nationwide study explores the changes in length of stay, recurrent hospitalization, functioning level, suicidality, violence and diagnoses of CAP inpatients in Finland in 2000, 2011 and 2018. We obtained comprehensive questionnaire data on each study year from 93 to 95% of all CAP wards in Finland. We split the 1276 inpatients into two age groups in each study year: under 13 and 13-18. The median length of stay in inpatient treatment decreased from 82.0 days in 2000 to 20.5 days in 2018 (p < 0.001) and recurrent hospitalization increased from 38 to 46%. General functioning, which was evaluated by the Children's Global Assessment Scale, deteriorated by an average of six points between 2000 and 2018. Violent threats decreased from 21.5 to 16.6% and violent acts decreased from 26.9 to 20.3%. Suicidal threats decreased from 42.6 to 23.3% in those aged under 13 and remained stable among those aged 13-18. In the 13-18 group, there was an increase in the diagnoses of ADHD, from 5.0 to 16.9% and depression, from 25.1 to 41.7%. However, psychosis decreased from 23.2 to 12.6% in the older age group. In the whole cohort, anxiety disorders increased from 7.6 to 15.6%. The overall picture does not show that CAP inpatients have become more disturbed. While the general functioning of CAP inpatients deteriorated somewhat over the 2000-2018 study period, symptoms of suicidality and violence remained stable or decreased. There was also a continuous increase in short-term treatment.

Abstract
Background Being among the youngest in class has previously been associated with attention-deficit/hyperactivity disorder (ADHD) and academic disadvantage, but the relative age effect on learning disorders is less well understood. This study examined whether relatively young children are more likely to be diagnosed with specific learning disorders than their older peers. Methods The setting included all 388,650 children born singleton in Finland from 1996 to 2002. Cases diagnosed with specific learning disorders in specialized health care by the age of 10 were identified from national registers. Cumulative incidences of specific learning disorders and the corresponding incidence rate ratios (IRRs) and 95% confidence intervals (CIs) were calculated for each birth month compared to January. Results During follow-up, 3162 (0.8% of 388,650) children were diagnosed with a specific learning disorder. Children born in December displayed higher cumulative incidences for specific learning disorders than children born in January (IRR: 1.77, 95% CI: 1.50-2.11). The findings were similar for girls (IRR: 2.01, 1.44-2.83) and boys (IRR: 1.70, 1.39-2.08). ADHD did not explain the association, as the IRR for the youngest children with specific learning disorders and ADHD was 1.59 (1.13-2.26) compared to those without ADHD (IRR: 1.84, 1.51-2.24). Conclusions Relatively younger children in Finnish schools were more likely to be diagnosed with a specific learning disorder by the age of 10. Increased awareness of how relative age differences affect the likelihood for children to be diagnosed with specific learning disorders is needed among parents, clinicians, and teachers.

Abstract
AIM To assess whether relative age was associated with bullying involvement and whether the associations were independent of child psychiatric symptoms. METHODS Bullying was assessed among 8576 children in the second grade, aged 8 years, by using four cross-sectional population-based studies with identical methodology completed by children, parents and teachers in 1989 (response rate 97%), 1999 (93%), 2005 (90%) and 2013 (86%). The main outcomes were bullying victimisation and perpetration. Odds ratios (OR) and 95% confidence intervals (95% CI) were calculated with the relatively oldest as the reference group and adjusted for child psychiatric symptoms. RESULTS The relatively youngest children, born September to December, were compared with the relatively oldest, born January to April. The youngest children had increased odds of being victims according to child (OR 1.2, 95% CI 1.1-1.4) and parent reports (OR 1.2 95% CI 1.008-1.4). The youngest also had decreased odds of being perpetrators according to child (OR 0.8, 95% CI 0.7-0.96) and teacher reports (OR 0.8, 95% CI 0.7-0.95). These findings were independent of psychiatric symptoms. CONCLUSION The relative age effects which were found in bullying involvement were independent of psychiatric symptoms. Considering this newly recognised risk factor for victimisation is important within anti-bullying practices.

Abstract
OBJECTIVES The youngest children in a classroom are at increased risk of being medicated for attention-deficit/hyperactivity disorder (ADHD). We examined the association between children's birth month and ADHD medication rates in Finland. METHODS Using a population-based study, we analyzed ADHD medication use among children born in 2005 to 2007. Cases (n = 7054) were identified from the first purchase of medication for ADHD. Cox proportional hazard models and hazard ratios (HRs) were examined by birth month and sex. Finnish children start first grade in the year of their seventh birthday. The cutoff date is December 31. RESULTS Risk of ADHD medication use increased throughout the year by birth month (ie, January through April to May through August to September through December). Among boys born in September to December, the association remained stable across cohorts (HR: 1.3; 95% confidence interval [CI]: 1.1-1.5). Among girls born in September to December, the HR in the 2005 cohort was 1.4 (95% CI: 1.1-1.8), whereas in the 2007 cohort it was 1.7 (95% CI: 1.3-2.2). In a restricted follow-up, which ended at the end of the year of the children's eighth birthday, the HRs for boys and girls born in September to December 2007 were 1.5 (95% CI: 1.3-1.7) and 2.0 (95% CI: 1.5-2.8), respectively. CONCLUSIONS Relative immaturity increases the likelihood of ADHD medication use in Finland. The association was more pronounced during the first school years. Increased awareness of this association is needed among clinicians and teachers.

Abstract
Aims: This study examined medication use for attention-deficit/hyperactivity disorder (ADHD) among children and adolescents by gender in Finland during 2008-2018. Methods: Aggregated data on medication use for ADHD from 2008 to 2018 were extracted from the nationwide register on reimbursed prescriptions. The annual prevalence of ADHD medication use was calculated as the number of children (6-12 years) and adolescents (13-17 years) per calendar year with at least one ADHD medication purchase divided by the number of children and adolescents in the population. Population prevalence for children was also examined by birth month. Results: In 2008, the prevalence rates for males were 1.26% in children and 0.93% in adolescents, and for females 0.21% and 0.14%, respectively. In 2018, the prevalence rates for males were 4.42% in children and 4.21% in adolescents, and for females 0.99% and 1.28%, respectively. Male-to-female ratios decreased during the study period from 6.0:1 to 4.5:1 (children) and from 6.6:1 to 3.3:1 (adolescents). ADHD medication use was more common among males and females (aged 6-12 years) born in May-August or September-December than among males and females born in January-April. Conclusions: The prevalence of ADHD medication use has continued to increase in Finland. Although use has increased more rapidly among females resulting in lower male-to-female ratios, medication use among females is considerably lower compared with males. Consequently, gender discrepancy in 2018 was relatively large, particularly among children. Future studies should also consider reporting annual prevalence by children's birth month.

Abstract
BACKGROUND The present study examines discrepancies between self- and adult-perceptions of social competence in children with attention deficit-hyperactivity disorder (ADHD), autism spectrum disorders (ASD) and possible co-morbid disruptive behaviour disorders (DBD). METHOD Self-reported questionnaires were collected from multiple informants at the baseline of a multi-systemic family intervention programme for children (aged 5-12) with ADHD, ASD and possible co-morbid DBD. In total, out of the 154 families eligible for the study, information was received concerning children from 124 families (children n = 121; mothers n = 117; fathers n = 86; teachers n = 97). In addition to this, a comparison community sample of 318 school-aged children (approximately 10 years old) was utilized to examine the perceptions of children's social competence across intervention and population groups in more detail. RESULTS Children's self-perceptions in the prosocial dimension of social competence (i.e. cooperating skills, empathy) did not differ between the intervention and comparison groups. Interestingly, the children in the intervention sample expressed more impulsivity and disruptiveness - the antisocial dimension of social competence - when compared with the children in the comparison sample. Adult ratings demonstrated that mothers, fathers and teachers reported decreased prosocial behaviour and increased antisocial behaviour across overall dimensions and sub-dimensions when compared with adults' ratings of elementary school children. Informant discrepancies between self-ratings and adult ratings across intervention groups yielded significant effect sizes (eta-squared) across all domains of social competence ranging from .09 to .25. CONCLUSION Children's positive self-ratings of social competence relative to adult ratings increased within intervention sample when compared with population sample. The intervention sample children appeared to acknowledge their social competence deficits, yet self-perceptions were inflated relative to adult ratings when focusing on peer relationship difficulties, particularly, aggression to peers.

Abstract
Psychosocial family-based interventions--family therapy, cognitive-behavioral parent training and family-based treatment protocols--are empirically supported treatments for children with attention deficit hyperactivity disorder (ADHD), oppositional defiant disorder, and conduct disorder. Well-researched interventions such as remote and group-based parent training programs relate to improvements in parenting quality, positive parenting, and the child's decreased ADHD and conduct behavioral problems, whereas individual family-based treatments are sometimes required, depending on symptom severity. Specific family-based treatment protocols are tailored for older children and adolescents with severe behavioral and emotional problems. Considering the above, empirically supported programs are used more in Finland, compared to licensed Anglo-American treatment protocols.

Abstract
Glial cell line-derived neurotrophic factor (GDNF) is a potent survival factor for nigrostriatal dopaminergic, central cholinergic, and motoneurons. GDNF also prevents the neuronal loss in experimental animal models for Parkinson's disease (PD). We have now investigated the GDNF gene for possible mutations in a group of nonfamilial PD and other patients. By cleavase fragment length polymorphism (CFLP) analysis and direct sequencing of the full coding region of GDNF gene we found a novel GDNF sequence variant in 1 of 30 PD patients. The alteration does not change the predicted amino acid sequence and it was also found in 1 of 20 patients without PD, suggesting that it represents a polymorphism in the gene. No other sequence variations were found. We conclude therefore that mutations in the GDNF coding region are not commonly contributing to the pathogenesis of PD.

Abstract
The penetration of azidocillin and ampicillin into the middle ear effusion after oral administration was studied and compared with blood levels of the drugs. In acute otitis media one hour after a single oral dose of azidocillin (15 mg/kg) 1.56 +/- 0.44 microgram/ml of the drug was found in the effusion fluid; after 2 hours the fluid contained 3.21 +/- 0.87 microgram/ml and after 12 hours,0.84 +/- 0.13 microgram/ml. The concentrations of ampicillin were 1.15 +/- 0.23 microgram/ml after one hour, 2.17 +/- 0.46 microgram/ml after 2 hours and 1.09 +/- 0.22 microgram/ml after 8 hours following a single oral dose of 10 mg/kg. Both drugs stay longer in the middle ear secretion than in the blood. This persistence supports the administration of azidocillin twice daily in acute otitis media. In contrast, the penetration of the drugs into the middle ear effusion fluid was poor in secretory otitis media, where the levels of the drugs were significantly lower.

Abstract
Acidocillin levels were determined in the middle ear exudates and serum of patients with acute exudative otitis media after oral administration of the drug. Acidocillin rapidly diffused exudate into the ear and its level in the exudate in 1 hour was 0-1.7 gamma/ml. At the same time the serum levels ranges within 4 to 25 gamma/ml. acidocillin remained longer in the ear exudate than in the serum. In 12 hours 0.2 to 1.3 gamma/ml of acidocillin was still found in the exudates, while there was no antibiotic in the serum.

Abstract
The possible immunosuppressive properties of the combination sulphamethoxazole-trimethoprim or either of the agents alone were studied in healthy human volunteers. The effect of the 4-day drug treatment on the antibody synthesis after vaccination was measured by titrating tetanus antitoxin, mumps antibody and Salmonella Hb antibody levels 4 and 5 weeks after vaccination. No significant differences were found in mumps or Salmonella antibody titres in the drug-treated group compared to controls. Tetanus antitoxin levels, however, were significantly lower than in controls after the combined drug. When a fourfold or greater increase in tetanus antitoxin titre was obtained in 75% of controls, the respective figures were 38% in the sulphamethoxazole-trimethoprim-treated group (p less than 0.05), 45% in the trimethoprim group (p greater than 0.05), and 50% in the sulphamethoxazole group (p greater than 0.05). The implications of these findings are discussed.
