Abstract
Introduction Anxiety disorders (ADs) are common in childhood and adolescence and global estimates suggest they affect 6.5% of individuals under 19 years of age.Yet, there has been a lack of research on time trends and socio-demographic risks for children and adolescents who receive treatment for ADs. Objectives We aim to fill gaps in our knowledge by examining a nationwide sample of Finnish children and adolescents diagnosed in specialized healthcare settings. Methods We used register data of all singleton children born in Finland from 1992-2006 and diagnosed with ADs from 1998-2012. Changes in time trends in incidence were studied by dividing the study sample into three cohorts by birth years: 1992-1996, 1997-2001 and 2002-2006. The 22,388 individuals with ADs were matched with 76,139 controls. Nested case-control design was used to study the socio-demographic risk factors. Results Comparing the 1992-1996 and 2002-2006 cohorts showed the cumulative incidence of treated ADs at the age of 10 increased from 0.3% to 1.2% (females) and 0.46% to 1.9% (males). Subjects had higher odds of being diagnosed with an AD if mothers had low SES (OR 1.49, 95% CI 1.42-1.58) and were single parents (OR 1.99, 95% CI 1.84-2.15) at birth. Unipolar depression was the most common psychiatric comorbidity (31.2%). Conclusions
ADs diagnosed by specialized services increased from 1998-2012 in both genders. This could indicate real increase in overall ADs, an increase in seeking treatment or both phenomena. The findings on maternal socioeconomic status and single parenting help improve understanding of environmental risk for anxiety disorders among children and adolescents. Disclosure No significant relationships.

Abstract
Background: The majority of childhood cancer survivors (CCSs) have been exposed to cardiotoxic treatments and often present with modifiable cardiovascular risk factors. Our aim was to evaluate the value of left ventricular (LV) longitudinal strain for increasing the sensitivity of cardiac dysfunction detection among CCSs. Methods: We combined two national cohorts: neuroblastoma and other childhood cancer survivors treated with anthracyclines. The final data consisted of 90 long-term CCSs exposed to anthracyclines and/or high-dose chemotherapy with autologous stem cell rescue and followed up for > 5 years and their controls (n = 86). LV longitudinal strain was assessed with speckle tracking (Qlab) and LV ejection fraction (EF) by three-dimensional echocardiography (3DE). Results: Of the CCSs, 11% (10/90) had abnormal LV longitudinal strain (i.e., < -17.5%); of those, 70% (7/10) had normal 3DE LV EF. Multivariable linear model analysis demonstrated that follow-up time (p = 0.027), sex (p = 0.020), and BMI (p = 0.002) were significantly associated with LV longitudinal strain. Conversely, cardiac risk group, hypertension, age, cumulative anthracycline dose or exposure to chest radiation were not. Conclusion: LV longitudinal strain is a more sensitive method than LV EF for the detection of cardiac dysfunction among CCSs. Therefore, LV longitudinal strain should be added to the screening panel, especially for those with modifiable cardiovascular risk factors.

Abstract
Metabolic syndrome (MetS) is a growing concern in survivors of pediatric hematopoietic stem cell transplantation (HSCT), but little is known about the underlying mechanisms. This study aimed to determine the prevalence and clinical presentation of MetS in male long-term survivors of pediatric HSCT and to investigate predisposing factors, including low-grade inflammation, altered fat distribution, and low testosterone levels. We included 98 survivors age 19 to 47 years at a median follow-up of 18 years (range, 8 to 35 years) after pediatric HSCT. MetS was defined according to the National Cholesterol Education Program Adult Treatment Panel III criteria. The prevalence and clinical manifestations of MetS were compared between our cohort and a control group of males from the background population (n = 4767). Fat distribution was assessed by android/gynoid ratio from a whole-body dual-energy X-ray absorptiometry scan. Systemic inflammation was evaluated by IL-6 and high-sensitivity C-reactive protein (hsCRP). Serum testosterone levels were measured in morning samples. The prevalence of MetS was 30%, corresponding to the prevalence in the 50- to 80-year-old males from the background population. In individuals with MetS, hyperglycemia was more frequent in the HSCT survivors compared with age-matched controls with MetS (76% versus 20%; P < .001), whereas hypertension was more dominant in the control group with MetS (69% versus 93%; P = .01). In addition, normal or low body mass index was more commonly observed among HSCT survivors with MetS compared with age-matched controls with MetS (41% versus 11%; P = .002). MetS was more often associated with total body irradiation (TBI) compared with chemotherapy regimens (odds ratio [OR], 4.3; 95% confidence interval [CI], 1.2 to 24.4; P = .02), lower testosterone levels (OR, 5.4; 95% CI, 1.3 to 23.6; P = .02), higher IL-6 levels (OR, 1.8; 95% CI, 1.2 to 2.8; P = .004), and higher hsCRP levels (OR, 1.8; 95% CI, 1.3 to 2.6; P < .001) (estimates per 2-fold increase). In addition, an increased android/gynoid (AG) fat ratio was strongly associated with MetS (OR, 2.1; 95% CI, 1.5 to 2.9; P < .001), even though only 7% of patients met the criteria for increased abdominal circumference. Our results indicate an increased risk of MetS in early adulthood after pediatric HSCT. The clinical manifestations differed from those seen in age-matched controls with MetS, indicating different pathophysiology driven by hyperglycemia, altered fat distribution (despite no clinical abdominal obesity), and low-grade inflammation. Risk factors included TBI-based conditioning and low testosterone levels. These results underline the importance of continuous clinical assessment of the cardiometabolic risk profile and stress the presence of important dissimilarities in the pathophysiology of MetS in HSCT survivors compared with the background population.

Abstract
Changes in body composition related to metabolic syndrome are frequent among survivors of haematopoietic stem cell transplantation (HSCT), but insights into predisposing factors are incomplete, and it is unknown to what degree these changes persist at long term. We cross-sectionally investigated body composition by dual-energy X-ray absorptiometry in 98 male survivors of paediatric allogeneic HSCT. Median (range) age at follow-up was 28.1 (18.5-47.0) years and median (range) time from transplant was 18.3 (7.7-34.6) years. Lean Body Mass Index and Skeletal Muscle Mass Index were lower in patients compared to the reference population (mean (SD) standard deviation score (SDS) -1.29 (0.99), p < 0.001 and -1.20 (1.03), p < 0.001). Fat Mass Index was comparable to the reference population, but android/gynoid (AG) fat ratio SDS was higher (mean (SD) 0.46 (1.28), p < 0.001). These changes were found in patients treated with total body irradiation (TBI) as well as non-TBI regimens, although most pronounced in the former. Further, low lean mass was associated with chronic graft-versus-host disease, while high AG ratio was associated with lower testosterone levels. Since the combination of low lean mass and high AG ratio increases the risk of cardio-metabolic disease, these health issues should be monitored at long-term clinical follow-up after paediatric HSCT.

Abstract
BACKGROUND Patients with high-risk neuroblastoma (HR NBL) treated with myeloablative regimens are reported to be at risk for cardiovascular morbidity, and this risk may be increased by impaired renal function. PROCEDURE Long-term renal function was assessed in a national cohort of 18 (age 22.4 ± 4.9 years) HR NBL survivors by plasma creatinine (P-Cr), urea, and cystatin C (P-Cys C) concentrations, urine albumin/creatinine ratio (ACR), and estimated glomerular filtration rate (eGFR). Ambulatory blood pressure was monitored, and common carotid intima-media thickness (CIMT) and left ventricular mass index (LVMI) were evaluated. RESULTS No significant difference in P-Cr, P-Cys C, or eGFR was found between the NBL survivors and the age- and sex-matched 20 controls. P-Cys C-based eGFR (eGFRcysc) was significantly lower than the P-Cr-based eGFRcr (97 ± 17 mL/min/1.73 m2 vs 111 ± 19 mL/min/1.73 m2 , P < 0.001) among the NBL survivors. The eGFRcysc was below normal in 28%, and ACR was above normal in 22% of the NBL survivors. Abnormal blood pressure was found in 56% of the survivors, and an additional 17% were normotensive at daytime but had significant nocturnal hypertension. Both ACR and P-Cys C were associated with nighttime diastolic hypertension. CONCLUSIONS Long-term survivors of childhood HR NBL showed signs of only mild renal dysfunction associated with diastolic hypertension. Elevated ACR and P-Cys C were the most sensitive indicators of glomerular renal dysfunction and hypertension in this patient cohort.

Abstract
There are many known endocrine complications after allogeneic hematopoietic stem cell transplantation (HSCT) in childhood including increased risk of biochemical hypogonadism. However, little is known about sexuality in adulthood following childhood HSCT. In this multicenter study, sexual functions and possible risk factors were assessed comprehensively in two national cohorts (Finland and Denmark) of male adult survivors of childhood HSCT. Compared to a healthy control group (n = 56), HSCT survivors (n = 97) reported less sexual fantasies, poorer orgasms, lower sexual activity with a partner and reduced satisfaction with their sex life, even in the presence of normal erectile functions and a similar frequency of autoerotic acts. Of the HSCT survivors, 35% were cohabitating/married and 66% were sexually active. Risk factors for poorer self-reported sexual functions were partner status (not cohabitating with a partner), depressive symptoms, CNS and testicular irradiation. Sexual dysfunction increased by age in the HSCT group with a pace comparable to that of the control group. However, because of the lower baseline level of sexual functions in the HSCT group, they will reach the level of clinically significant dysfunction at a younger age. Hence, male survivors of childhood HSCT should be interviewed in detail about their sexual health beyond erectile functions.

Abstract
Male gonadal dysfunction is a frequent late effect after pediatric hematopoietic stem cell transplantation (HSCT), but detailed insight into patterns of male gonadal function at long-term is limited by retrospective studies without semen sample data. In this study, we investigated the risk of azoospermia and testosterone deficiency, the diagnostic value of markers of spermatogenesis, and paternity at long-term follow-up after pediatric allogeneic HSCT. All male HSCT survivors age ≥18 years, transplanted in Denmark or Finland between 1980 and 2010, were invited to participate in this cross-sectional study. Examinations included a semen sample, measurements of reproductive hormones and testicular volume, and screening for chronic graft-versus-host disease (GVHD). Cumulative (pre-HSCT plus HSCT) treatment doses were calculated. Of 181 eligible patients, 98 participated, at a median 18 years (range, 8 to 35 years) after undergoing HSCT. Sperm was found in 30 patients, azoospermia in 42, and azoospermia during testosterone substitution in 24. A higher cumulative testicular irradiation dose was associated with increased risk of azoospermia and testosterone substitution (odds ratio [OR] per +1 Gy, 1.27; 95% confidence interval [CI], 1.14 to 1.46 [P < .001] and 1.21; 95% CI, 1.11 to 1.38 [P < .001], respectively). All patients treated with >12 Gy had azoospermia, and all but 1 patient treated with >16 Gy needed testosterone substitution. In patients treated with chemotherapy only (n = 23), a higher cumulative cyclophosphamide equivalent dose was associated with an increased risk of azoospermia (OR per +1 g/m2, 1.34; 95% CI, 1.01 to 2.15; P = .037). Prepubertal stage at HSCT was a risk factor for testosterone substitution (OR, 15.31; 95% CI, 2.39 to 315; P = .017), whereas chronic GVHD was unrelated to gonadal dysfunction. Inhibin B was the best surrogate marker of azoospermia (area under the curve, .91; 95% CI, .85 to .98; 90% sensitivity and 83% specificity) compared with follicle-stimulating hormone and testicular volume. Of 24 males who had attempted to conceive, 6 had fathered children. In conclusion, the risk of male gonadal dysfunction after pediatric HSCT is high and depends primarily on the cumulative testicular irradiation dose and pubertal stage at transplantation. Our findings support the need for fertility preservation before HSCT, as well as for prolonged follow-up of pediatric HSCT recipients into adulthood.

Abstract
Introduction: Dental anxiety is common and causes symptomatic use of oral health services. Objectives: The aim was to study if a short-term virtual reality intervention reduced preoperative dental anxiety. Methods: A randomized controlled single-center trial was conducted with 2 parallel arms in a public oral health care unit: virtual reality relaxation (VRR) and treatment as usual (TAU). The VRR group received a 1- to 3.5-min 360° immersion video of a peaceful virtual landscape with audio features and sound supporting the experience. TAU groups remained seated for 3 min. Of the powered sample of 280 participants, 255 consented and had complete data. Total and secondary sex-specific mixed effects linear regression models were completed for posttest dental anxiety (Modified Dental Anxiety Scale [MDAS] total score) and its 2 factors (anticipatory and treatment-related dental anxiety) adjusted for baseline (pretest) MDAS total and factor scores and age, taking into account the effect of blocking. Results: Total and anticipatory dental anxiety decreased more in the VRR group than the TAU group (β = −0.75, P < .001, for MDAS total score; β = −0.43, P < .001, for anticipatory anxiety score) in patients of a primary dental care clinic. In women, dental anxiety decreased more in VRR than TAU for total MDAS score (β = −1.08, P < .001) and treatment-related dental anxiety (β = −0.597, P = .011). Anticipatory dental anxiety decreased more in VRR than TAU in both men (β = −0.217, P < .026) and women (β = −0.498, P < .001). Conclusion: Short application of VRR is both feasible and effective to reduce preoperative dental anxiety in public dental care settings (ClinicalTrials.gov NCT03993080). Knowledge Transfer Statement: Dental anxiety, which is a common problem, can be reduced with short application of virtual reality relaxation applied preoperatively in the waiting room. Findings of this study indicate that it is a feasible and effective procedure to help patients with dental anxiety in normal public dental care settings.

Abstract
Chronic diseases are known to cause premature aging and frailty. Data about telomere length and telomere length-regulating proteins after pediatric KTx are scarce. Leukocyte telomere length and gene expression level of eight telomere-binding proteins were analyzed in 20 KTx recipients, eight childhood NBL survivors, and nine healthy controls. The influence of key clinical parameters on telomere length and on regulators of telomere length was evaluated. The telomere length in the KTx recipients tended to be shorter (0.53 AU) than in the healthy controls (0.64 AU) but longer than in the NBL survivors (0.38 AU). There was no significant difference in telomere length between the NBL survivors and the KTx recipients (P = .110). The gene expression level of telomere length-preserving protein RPA1 was significantly higher in the KTx recipients than among the NBL survivors or healthy controls, while the expression of TRF2 and the tumor suppressor gene p16 was significantly higher in the KTX recipients when compared to the controls. TRF2 and TIN2 correlated significantly with hsCRP; additionally, TRF2 showed significant correlation with plasma creatinine and eGFR. KTx recipients have near to normal telomere length, but they have significantly higher gene expression levels of telomere regulatory proteins compared with healthy controls, suggesting activation of mechanisms preserving telomere length among KTx recipients. Our results suggest that declined graft function and consequent inflammatory response may have influence on telomerase activity.

Abstract
Background: Psychiatric disorders tend to be developmental, and longitudinal settings are required to examine predictors of psychiatric phenomena. Replicating and combining data and results from different birth cohorts, which are a source of reliable data, can make research even more valuable. The Finnish Psychiatric Birth Cohort Consortium (PSYCOHORTS) project combines birth cohorts in Finland. Aim: The aim of this paper is to introduce content, plans and perspectives of the PSYCOHORTS project that brings together researchers from Finland. In addition, we illustrate an example of data harmonization using available data on causes of death. Content: PSYCOHORTS includes eight Finnish birth cohorts. The project has several plans: to harmonize different data from birth cohorts, to incorporate biobanks into psychiatric birth cohort research, to apply multigenerational perspectives, to integrate longitudinal patterns of marginalization and inequality in mental health, and to utilize data in health economics research. Data on causes of death, originally obtained from Finnish Cause of Death register, were harmonized across the six birth cohorts using SAS macro facility. Results: Harmonization of the cause of death data resulted in a total of 21,993 observations from 1965 to 2015. For example, the percentage of deaths due to suicide and the sequelae of intentional self-harm was 14% and alcohol-related diseases, including accidental poisoning by alcohol, was 13%. Conclusions: PSYCOHORTS lays the foundation for complex examinations of psychiatric disorders that is based on compatible datasets, use of biobanks and multigenerational approach to risk factors, and extensive data on marginalization and inequality.

Abstract
Background: Neuroblastoma is the most common extra-cranial solid tumor in children. Intensive therapy including autologous stem-cell transplantation (HSCT) has improved the poor prognosis of high-risk neuroblastoma (HR-NBL) but may impair gonadal function. Objectives: To investigate the gonadal function and fertility in long-term survivors of childhood HR-NBL. Design: A cohort including all Finnish (n = 20; 11 females) long-term (>10 years) survivors of HR-NBL and an age- and sex-matched control group (n = 20) was examined at a median age of 22 (16-30) years. Oncologic treatments, pubertal timing, hormonal therapies and the number of off-spring were recorded, and pituitary and gonadal hormones were measured. Results: Altogether 16/20 of the long-term survivors of HR-NBL entered puberty spontaneously; puberty was hormonally induced in four survivors (three females). Among the 8/11 female survivors with spontaneous puberty, seven had spontaneous menarche, but 5/8 developed ovarian failure soon after puberty. Nine females currently needed estrogen substitution. AMH, a marker of ovarian reserve, was lower in the female survivors than controls (median 0.02 vs. 1.7 μg/l, p < 0.001). As a group, male survivors had smaller testicular size (8.5 vs. 39 ml, p < 0.001) and lower inhibin B (<10 vs. 170 ng/l, p < 0.001) compared with control males, with altogether 6/9 survivor males fulfilling the criteria of gonadal failure (absent puberty, small testicle size or increased FSH with need of testosterone substitution). Gonadal failure was more common in female and male survivors treated with total-body irradiation. Three survivors (one male) had offspring, all treated without total-body irradiation and moderate dose of alkylating chemotherapy. Growth velocity was compromised in all survivors after HR-NBL diagnosis, with absent pubertal growth spurt in 7/17 survivors with complete growth data. Conclusion: Gonadal failure is common in long-term survivors of HR-NBL treated with HSCT. Fertility may be preserved in some survivors treated without total-body irradiation.

Abstract
Background:
Research studies exploring the determinants of disease require sufficient statistical power to detect meaningful effects. Sample size is often increased through centralized pooling of disparately located datasets, though ethical, privacy and data ownership issues can often hamper this process. Methods that facilitate the sharing of research data that are sympathetic with these issues and which allow flexible and detailed statistical analyses are therefore in critical need. We have created a software platform for the Virtual Pooling and Analysis of Research data (ViPAR), which employs free and open source methods to provide researchers with a web-based platform to analyse datasets housed in disparate locations.
Methods:
Database federation permits controlled access to remotely located datasets from a central location. The Secure Shell protocol allows data to be securely exchanged between devices over an insecure network. ViPAR combines these free technologies into a solution that facilitates ‘virtual pooling’ where data can be temporarily pooled into computer memory and made available for analysis without the need for permanent central storage.
Results:
Within the ViPAR infrastructure, remote sites manage their own harmonized research dataset in a database hosted at their site, while a central server hosts the data federation component and a secure analysis portal. When an analysis is initiated, requested data are retrieved from each remote site and virtually pooled at the central site. The data are then analysed by statistical software and, on completion, results of the analysis are returned to the user and the virtually pooled data are removed from memory.
Conclusions:
ViPAR is a secure, flexible and powerful analysis platform built on open source technology that is currently in use by large international consortia, and is made publicly available at [
http://bioinformatics.childhealthresearch.org.au/software/vipar/

Abstract
STUDY QUESTION Does IVF increase the risk of autism spectrum disorders (ASDs)? SUMMARY ANSWER No association between IVF and ASDs or any of its subtypes was found in this sample. WHAT IS KNOWN ALREADY Certain prenatal factors may increase the risk of ASDs. Studies on the association between IVF and ASDs have shown inconsistent results. IVF is known to increase the risk of perinatal problems but many of them are related to multiple pregnancies. STUDY DESIGN, SIZE, DURATION This case-control study included 4164 autistic cases and 16 582 matched controls born in Finland in 1991-2005. The cases were diagnosed with ASDs by the year 2007. The maximum age at diagnosis was 16 years. PARTICIPANTS/MATERIALS, SETTING, METHODS Four controls were matched to each case. For singletons the matching criteria were date of birth, place of birth, sex and residency in Finland. For twins the birth order within a twin pair was included as well. In the whole sample, there were 63 cases (1.51%) and 229 controls (1.38%) born after IVF. MAIN RESULTS AND THE ROLE OF CHANCE No significant association was found between IVF and ASDs (adjusted odds ratio (OR): 0.9, 95% confidence interval (CI): 0.7-1.3) or its subtypes childhood autism (OR: 0.8, 95% CI: 0.4-1.5), Asperger's syndrome (OR: 0.9, 95% CI: 0.5-1.6) or other pervasive developmental disorder (OR: 1.0, 95% CI: 0.6-1.6). When only singletons were included, there was an association between IVF and Asperger's syndrome in an unadjusted analysis (OR: 2.0, 95% CI: 1.1-3.5) but this was not significant when adjusted for mother's socioeconomic status or parity. When the analyses were conducted separately for boys and girls, there was a significant association between IVF and Asperger's syndrome for boys in an unadjusted analysis (OR: 2.1, 95% CI: 1.2-3.7) but this was not significant in the final adjusted model. LIMITATIONS, REASONS FOR CAUTION Information both on IVF and on ASDs was based on registers and it is possible that there is some misclassification. No information on different subtypes of IVF or other assisted reproduction techniques was available. Statistical power may have been insufficient. WIDER IMPLICATIONS OF THE FINDINGS This study showed no increased risk of ASDs in children born after IVF but studies with larger sample sizes and information on different subtypes of IVF are needed to confirm the finding. STUDY FUNDING/COMPETING INTEREST(S) The study was supported by Autism Speaks, NIMH 1K02-MH65422 and NIEHS 1R01ES019004. There are no competing interests.
