Abstract
Data on alanine aminotransferase (ALT) measurement practices and diagnoses associated with increased values are limited. We evaluated these issues by collecting ALT measurements from 1- to 16-year-old patients investigated in 1992-2018 in a tertiary center. Diagnoses were gathered in 2008-2018. Altogether 145,092 measurements from 28,118 children were taken 42% undergoing repeated testing. Testing increased from 21/1000 to 81/1000 children and the prevalence of elevated values fluctuated between 18% and 26%. An increase was seen especially in emergency care and departments of rheumatology, gastroenterology, hemato-oncology, and psychiatry. Common acute causes associated with elevated ALT were infections (45%), hemato-oncologic conditions (17%), and external reasons (13%), whereas autoimmune diseases (28%), psychiatric conditions (14%), and metabolic-dysfunction associated steatotic liver disease (10%) were common chronic causes. In conclusion, ALT testing increased 3.9-fold while the proportion of increased values remained stable, indicating that increased testing was justified. However, in some departments the testing efficiency was low.

Abstract
OBJECTIVES AND STUDY The often-recommended alanine aminotransferase (ALT) cutoffs (girls 21 U/l, boys 25 U/l) are based on a NHANES cohort. A novel concept of metabolic dysfunction associated steatotic liver disease (MASLD) emphasizes the role of ALT. We tested the prevalence of increased ALT and MASLD in children with overweight or obesity applying population-based and NHANES-based cut-offs. METHODS Six- to seventeen-year-old children underwent data collection in a prospective Physical Activity and Nutrition in Children (PANIC) study. ALT 95th percentiles were calculated from 1167 separate measurements considering various confounders. Test cohort comprised 1044 children with overweight/obesity. RESULTS ALT values increased at puberty onset (p = 0.031) and correlated negatively with age in girls (r = -0.222, p < 0.001). Particularly overall and central obesity increased ALT, whereas underweight or metabolic abnormalities had smaller effect. After applying the tested exclusions, the age-related ALT 95th percentiles were 24-29 U/l for girls and 29-32 U/l for boys. In 6-8-year-old children with overweight/obesity, the prevalence of increased ALT and MASLD were 21.6% and 2.4% with age-specific PANIC cutoffs. In older children, when NHANES-based cutoffs were used, there was a trend for higher prevalence of increased ALT and MASLD in all age groups for both sexes, reaching significance for increased ALT in 12-16-year-old boys (NHANES 63.5%, 95% confidence interval [CI]: 56.4%-70.0% vs. PANIC 47.1%, 95% CI [40.1%-54.2%]) and 9-11-year-old girls (60.0% [49.4%-69.8%] vs. 31.8% [22.8%-42.3%]), respectively. Increased ALT/MASLD were more common in boys than in girls, and in boys these increased with age, whereas in girls these peaked at age 9-12 years. CONCLUSION A reference population impacts on the prevalence of increased ALT and MASLD. Considering this help optimizing screening while avoiding unnecessary investigations and surveillance. The prospective part of this study is registered in clinicaltrials.gov; identifier NCT01803776.

Abstract
Introduction Data on the prevalence of pediatric fatty liver disease remain limited, partly due to challenges in diagnosis. A novel concept of metabolic-associated fatty liver disease (MAFLD) makes it possible to establish the diagnosis in overweight children with sufficiently elevated alanine aminotransferase (ALT). We investigated the prevalence, risk factors, and metabolic co-morbidities of MAFLD in a large group of overweight children. Methods Data on 703 patients aged 2-16 years examined due to overweight in different levels of healthcare in 2002-2020 were collected retrospectively from patient records. MAFLD was here defined as ALT >2x reference (>44 U/l in girls and >50 U/l in boys) in overweight children according to recently updated definition. Patients with MAFLD and without it were compared, and subgroup analyses were conducted among boys and girls. Results Median age was 11.5 years, and 43% were girls. Altogether 11% were overweight, 42% obese and 47% severely obese. Abnormal glucose metabolism was present in 44%, dyslipidemia in 51%, hypertension in 48% and type 2 diabetes (T2D) in 2%. MAFLD prevalence varied between 14-20% in examined years without significant change (p=0.878). The pooled prevalence over the years was 15% (boys 18%, girls 11%; p=0.018), peaking in girls at early puberty and increasing in boys with age and puberty. Associated factors in boys were T2D (OR 7.55, 95% CI 1.23-46.2), postpubertal stage (5.39, 2.26-12.8), increased fasting insulin (3.20, 1.44-7.10), hypertriglyceridemia (2.97, 1.67-5.30), hyperglycemia (2.88, 1.64-5.07), decreased high-density lipoprotein (HDL) cholesterol (2.16, 1.18-3.99), older age (1.28, 1.15-1.42) and higher body-mass-index (1.01, 1.05-1.15), and in girls T2D (18.1, 3.16-103), hypertriglyceridemia (4.28, 1.99-9.21), and decreased HDL (4.06, 1.87-8.79). Conclusion Prevalence of MAFLD was 15%, with no statistically significant increase in the 2000s. The condition was associated in general with male gender, puberty stage and disturbances in glucose and lipid metabolism, and higher age and BMI in boys.

Abstract
INTRODUCTION Imaging-confirmed uncomplicated acute appendicitis can be effectively and safely treated with antibiotics in most adults and children. Symptomatic treatment may have similar efficacy and safety. METHODS AND ANALYSIS The APPSYPP trial is a randomized national multicenter feasibility superiority pilot study comparing appendectomy with symptomatic treatment in children with imaging-confirmed uncomplicated acute appendicitis. INCLUSION CRITERIA 1) age ≥ 7 and < 16 years, 2) imaging-confirmed uncomplicated acute appendicitis and 3) CRP ≤ 65 mg/l. Patients are randomized to receive emergency laparoscopic appendectomy or symptomatic treatment. To ensure patient safety, symptomatically treated patients are hospitalized for at least 24 h receiving standard practice intravenous fluids and analgesics according to standard clinical practice. Primary outcome is 30-day treatment success defined by the absence of any treatment failure criteria. In appendectomy, treatment failure is defined as normal appendiceal histopathology or any postintervention complication requiring general anesthesia. In symptomatic treatment, treatment failure is defined as 1) inability for hospital discharge without appendectomy within 48 h after randomization with a finding of histopathologically inflamed appendix, 2) appendectomy during the initial hospital stay due to clinical progression of appendicitis with complicated acute appendicitis both histopathologically and surgically, 3) appendectomy with a histopathological finding of acute appendicitis after hospital discharge, or 4) any complication of appendicitis requiring general anesthesia. Detailed predefined secondary outcomes will be analyzed. ETHICS AND DISSEMINATION Study was approved by Ethics Committee of Helsinki University Hospital (ID:HUS/1993/2021), conducted in compliance with the declaration of Helsinki with results disseminated in peer-reviewed scientific journals. TRIAL REGISTRATION ClinicalTrials.gov (NCT05289713). STRENGTHS AND LIMITATIONS OF THIS STUDY

Abstract
OBJECTIVE Assessment of the upper gastrointestinal tract (UGI) may enable more personalized treatment strategies in pediatric inflammatory bowel disease (IBD). However, data on the frequency and significance of these findings remain limited. METHODS Data on 132 pediatric IBD patients with systematic UGI sampling were collected and the baseline characteristics and presence of complications compared between those with and without histological UGI findings. The control group comprised 162 children who received no diagnoses. RESULTS Seventy-six children had ulcerative colitis (UC), 47 Crohn's disease (CD) and nine IBD unclassified. UGI findings were more common in IBD patients than controls (69.7% vs. 30.9%, respectively, p < .001), particularly in the stomach (62.1% vs. 16.8%; p < .001). Among IBD patients, findings were more common in CD than in UC (80.9% vs. 63.2%; p = .038), particularly in the duodenum (21.3% vs. 2.6%, p = .001). Four patients had UGI granulomas consistent with CD. Hypoalbuminemia (OR 3.22; 95% CI 1.18-8.79) and failure to thrive (2.82; 1.17-6.78) increased the likelihood of UGI findings in IBD. In CD, perianal morbidity was less common in those with than in those without UGI findings (13.2% vs. 44.4%; p = .032) whereas in UC, UGI findings increased the risk for co-morbidities (18.8% vs. 3.6%; p = .059). The long-term outcomes did not differ between patients with or without UGI findings. CONCLUSIONS Histologic UGI findings were more common in children with IBD than in children with no gastrointestinal diagnoses. In CD, UGI findings were more frequent than in UC, especially in the duodenum. In UC, UGI findings were associated with more complex disease.

Abstract
OBJECTIVES The clinical significance of Helicobacter pylori-negative chronic gastritis (HPNCG) in children is unclear. We examined this issue in patients who had undergone esophagogastroduodenoscopy with systematic gastric sampling. METHODS Data of 1178 consecutive children who underwent diagnostic esophagogastroduodenoscopy were collected. Baseline characteristics and long-term outcomes were compared between children with active and inactive HPNCG and those with normal gastric histology. Follow-up data were available for up to 13 years. RESULTS Altogether 24 (2.0%) children had active and 235 (19.9%) inactive HPNCG, 27 (2.3%) were Hpylori-positive, 46 (3.9%) had other gastric pathology, and 846 (71.8%) normal histology. Diarrhea (31.3% vs 25.1%, P = 0.033), poor growth (23.6% vs 14.7%, P < 0.001), bloody stools (13.9% vs 7.2%, P < 0.001), anemia (46.5% vs 23.4%, P < 0.001), hypersedimentation (39.7% vs 21.4%, P < 0.001), hypoalbuminemia (40.4% vs 16.2%, P < 0.001), and elevated fecal calprotectin (62.4% vs 31.5%, P < 0.001) were more common and heartburn (13.9% vs 22.9%, P = 0.002) less common in the HPNCG group than in the controls. Both active (OR 3.64,95% CI 1.35-9.82) andinactive (2.98, 2.18-4.08) HPNCG predicted a diagnosis in the initial investigations. Crohn disease (41.7%) was the most common diagnosis in active HPNCG and celiac disease (37.4%) in inactive HPNCG. During follow-up, 7 (9.9%) of the 71 initially nondiagnosed HPNCG children received a diagnosis. CONCLUSIONS HPNCG is a frequent finding in children undergoing EGD, the active form being associated especially with Crohn disease and the inactive with celiac disease. The long-term prognosis of patients with HPNCG who do not receive an initial diagnosis is good.

Abstract
OBJECTIVES AND STUDY Gastrointestinal endoscopy is often performed when investigating abdominal complaints in children. While atrophic changes of the duodenal mucosa are usually caused by celiac disease, the prevalence and clinical significance of non-atrophic duodenal changes are less clear. We studied these issues in a large pediatric endoscopic cohort. METHODS Comprehensive data on clinical features, diagnostic findings and long-term outcomes of children who had undergone upper gastrointestinal endoscopy with systematic duodenal sampling were collected. Study variables were compared between children with non-atrophic changes and normal histology, and between those with non-atrophic changes who did and did not receive a diagnosis. RESULTS The study comprised 1,170 consecutive children, of whom 51 (4.4%) had non-atrophic and 315 (26.9%) atrophic duodenal changes and 804 (68.7%) normal histology. The most common non-atrophic findings were non-specific inflammation (n = 19) and intraepithelial lymphocytosis (n = 14). Patients with non-atrophic changes presented more often with blood in stools (23.5 vs. 11.3%; p = 0.009), anemia (43.2 vs. 36.5%; p = 0.028) and positive celiac serology (34.3 vs. 12.9%; p < 0.001) than those with a normal duodenum. Twenty-four (44%) of those with non-atrophic changes received an initial diagnosis, the most common of which were inflammatory bowel disease (IBD) (n = 8), Helicobacter pylori infection (n = 3) and food allergy (n = 3). The prevalence of the diagnoses did not differ from those with a normal duodenum. Those who received a diagnosis had more often blood in stools (37.5 vs. 11.1%; p = 0.027), anemia (70.6 vs. 20.0%; p = 0.002) and negative celiac serology (50.0 vs. 7.7%; p = 0.013) than those without diagnosis. During a follow-up of 6.1-13.3 years, five of the 12 initially undiagnosed seropositive patients developed celiac disease, and one patient also developed ulcerative colitis. CONCLUSION Non-atrophic duodenal changes are relatively common and associated with anemia, blood in stools, and positive celiac disease serology. Excluding potential celiac disease, those without an initial diagnosis have a favorable long-term prognosis.

Abstract
OBJECTIVES We evaluated the relationship between serum concentration and efficacy of adalimumab (ADA), an anti-tumor necrosis factor-alpha agent, in pediatric patients with inflammatory bowel disease (PIBD). MATERIALS AND METHODS This retrospective cross-sectional study traced 75 patients with PIBD (Crohn's disease, n = 57) treated with ADA at two tertiary centers in Finland in 2012-2018. Drug levels and drug antibody titers were chart-reviewed, and the treatment continuation rate of ADA therapy was evaluated. We also assessed the impact of trough levels in the first 3 months on the continuation of ADA within one year of therapy. RESULTS ADA was introduced at a median age of 13.4 years, and the median disease duration was 2.7 years. During the first year, 22 patients (29%) discontinued ADA due to either loss of response (20%, n = 15) or anti-drug antibody formation (5.3%, n = 4). Regarding trough levels in the first 3 months, 9/16 patients (56%) with trough levels <5 mg/L and 12/20 (60%) with trough levels <7.5 mg/L at 3 months discontinued the therapy by the end of the first year. In comparison, only 8/32 patients (25%) with trough levels >7.5 mg/L at 3 months discontinued treatment during the first year (p = .005). At the last follow-up (median 1.5 years), 52% of the 75 patients were on maintenance therapy and had a median trough level of 8.8 mg/L. CONCLUSION Higher trough levels in the first 3 months of adalimumab treatment are associated with lower rates of discontinuation due to loss of response during the first year.

Abstract
BACKGROUND Undelayed diagnosis is thought to be a major determinant for good prognosis in pediatric inflammatory bowel disease (PIBD). However, factors predicting diagnostic delay and the consequences of this remain poorly defined. We investigated these issues in a well-defined cohort of PIBD patients. METHODS Comprehensive electronic data were collected from 136 PIBD patients retrospectively. Diagnostic delay was further classified into < 6 and ≥ 6 months, and < 12 and ≥ 12 months. Logistic regression was used to calculate whether the delay was associated with clinical features and/or risk of complications and co-morbidities at diagnosis. RESULTS The median age of patients was 12.4 years and 43.4% were females. Altogether 35.5% had Crohn´s disease (CD), 59.1% ulcerative colitis (UC) and 6.6% IBD undefined (IBD-U). The median delay before diagnosis was 5.0 months in all, 6.6 months in CD, 4.1 months in UC, and 9.8 months in IBD-U (UC vs. CD, p = 0.010). In all but IBD-U most of the delay occurred before tertiary center referral. Abdominal pain predicted a delay > 6 months in all PIBD (OR 2.07, 95% CI 1.00-4.31) and in UC patients (3.15, 1.14-8.7), while bloody stools predicted a shorter delay in all PIBD (0.28, 0.14-0.59) patients and in CD (0.10, 0.03-0.41) patients. A delay > 6 months was associated with a higher frequency of complications (2.28, 1.01-5.19). CONCLUSIONS Delay occurred mostly before specialist consultation, was longer in children presenting with abdominal pain and in CD and was associated with risk of complications. These findings emphasize the roles of active case-finding and prompt diagnostic evaluations.

Abstract
Variable endoscopic and histological findings of esophageal lining are often detected in celiac disease, with unknown significance. We investigated the frequency and significance of such abnormalities in children. Macroscopic esophageal findings as reported by endoscopist and histological results by pathologist were compared between 316 celiac disease patients and 378 disease controls who had undergone upper gastrointestinal endoscopy with systematic esophageal biopsy sampling. Association between esophageal abnormalities and other clinical and histological characteristics of the disease was evaluated in celiac disease patients. Endoscopic esophageal findings were reported least often (3.8%) of all diseases in celiac disease, whereas histopathologic abnormalities were frequent (16.8%, n = 53). Children with celiac disease and esophageal histopathology reported more reflux than those with normal esophagus (5.7 vs. 0.8%, P = 0.032), whereas the groups were comparable in the frequency and severity of other symptoms, demographic data, prevalence of celiac disease-associated and other coexisting chronic conditions, family history of celiac disease, anthropometric and laboratory parameters, and degree of villous atrophy. Only 2 (3.7%) out of the 53 children with histologic findings had esophageal symptoms at diagnosis, and altogether seven were treated with acid blockers. Four children had increased number (≥15 eosinophils per high-power field) of esophageal eosinophils, but none of them had definite eosinophilic esophagitis. The remaining 45 children had only unspecific inflammation in the esophagus and reported no esophageal problems during a median of 6.9 years follow-up. To conclude, although relatively common, histopathological esophageal findings in celiac disease are mostly unspecific and without major clinical significance even in a long-term follow-up.

Abstract
STUDY OBJECTIVES To examine the associations between screen time, the time spent on different screen devices, and sleep in a sample of Finnish preschool children. METHODS The current study analyzed cross-sectional data from the DAGIS study carried out in Finland in 2015-2016 on 736 children aged 3-6 years. Parents reported in a 7-day diary the durations the child used screen devices daily, with separate details about watching TV or DVDs, using tablets or smartphones, and using computers. In addition, parents reported children's bedtimes and wake-up times, which were further used in calculating sleep duration. Parents answered questions regarding their child's sleep consistency. Statistical analyses included adjusted general linear modeling. RESULTS An hourly increase in total screen time was associated with 11 min later bedtime (p < 0.001) and 10 min shorter sleep duration (p < 0.001). More TV/DVD watching was associated with later bedtimes (p = 0.016) and a shorter sleep duration (p = 0.001). More smartphone/tablet use was associated with later bedtimes (p = 0.005), later wake-up times (p = 0.038), and weaker sleep consistency (p = 0.024). More computer use was associated with later bedtimes (p = 0.046). Results did not differ between genders. CONCLUSIONS Increased screen time was associated with later bedtimes and shorter sleep duration among preschool children. Adverse associations with sleep outcomes were found for each screen device. Attention should be paid to promoting balanced use of screens and regular sleep habits in young children.

Abstract
BACKGROUND Early detection of celiac disease could theoretically prevent most of the disease-associated complications, but long-term effects of this approach are unclear. AIMS To investigate features at diagnosis and adulthood health in celiac disease patients diagnosed in early childhood in 1965-2014. METHODS Medical data on 978 pediatric patients were collected and study questionnaires sent to 559 adult patients who were diagnosed in childhood. Results were compared between patients diagnosed in early (≤3.0 years) and later (3.1-17.9 years) childhood. RESULTS Early diagnosed patients (n=131) had more often total villous atrophy (37% vs 25%, p=0.001), gastrointestinal presentation (61% vs 47%, p<0.001), growth disturbances (70% vs 32%, p=0.001) and severe symptoms (30% vs 9%, p<0.001) and were less often screen-detected (10% vs 27%, p<0.001) at diagnosis than those diagnosed later (n=847). Among 239 adult responders, early diagnosed patients (n=36) had fewer comorbidities (33% vs 53%, p=0.034) but considered their health less often good/excellent (69% vs 84%, p=0.029). The groups were comparable in current age, dietary adherence, symptoms and health-related quality of life. CONCLUSION Despite more severe initial presentation, the long-term health in early diagnosed patients was mostly comparable or even better to those diagnosed later in childhood. Poorer self-perceived health suggests a need for support during the transition to adulthood care.

Abstract
BACKGROUND AND AIMS Intestinal diseases are regarded as a common cause of anemia, but the diagnostic outcomes of children with anemia undergoing endoscopic investigations are unclear. We investigated this issue in a large cohort of children. METHODS Indications for and findings of consecutive gastrointestinal (GI) endoscopies were collected. Clinical presentation and diagnostic outcomes were compared between anemic and nonanemic patients and between anemic patients with and without a diagnosis. Diagnoses received during follow-up were collected. RESULTS Of 2395 consecutive endoscopies, 251 children with and 613 children without anemia had undergone either diagnostic esophagogastroduodenoscopy (EGD) (51.4% and 51.4%, respectively), colonoscopy (4.0% and 11.4%), or both (45.8% and 37.8%). Children with anemia more often received diagnoses (72.9% vs 39.3%; odds ratio [OR], 4.18; 95% confidence interval [CI], 3.03-5.77), particularly of celiac disease (26.3% vs 15.5%, P < .001) and of inflammatory bowel disease (31.1% vs 9.1%, P < .001), than did nonanemic children. The diagnosis in anemic patients was predicted by age 5 to 12 years (OR, 3.52; 95% CI, 1.27-9.75), presence of diarrhea (OR, 2.04; 95% CI, 1.07-3.90), melena/hematochezia (OR, 2.40; 95% CI, 1.17-4.92), poor growth (OR, 3.94; 95% CI, 1.70-9.15), positive celiac serology (OR, 11.81; 95% CI, 3.47-40.12), high calprotectin (OR, 12.86; 95% CI, 4.00-41.32), hypersedimentation (OR, 2.65; 95% CI, 1.29-5.44), and hypoalbuminemia (OR, 5.05; 95% CI, 1.56-16.34). Thirty children with anemia (12.0%) had no GI symptoms, and 22 of them (73.3%) were given diagnoses at the time of the endoscopies. All 22 had additional laboratory abnormalities, whereas these were present in only 2 of 8 undiagnosed children. None of them was diagnosed later in the follow-up of up to 11 years, in contrast to 4 (6.7%) of all anemic and 33 (8.9%) of all nonanemic patients. CONCLUSIONS Anemia increased the probability of being given a diagnosis, emphasizing its importance as an alarm symptom. However, endoscopies in anemic patients without additional symptoms or laboratory abnormalities seldom improved the diagnostic yield.

Abstract
Background Type 1 tyrosinemia is a hereditary metabolic disease in which tyrosine metabolites damage the liver and kidneys. Nitisinone medication revolutionized the treatment, but the effects of the drug during human pregnancy are unknown. Case presentation A 17-year-old tyrosinemia patient became pregnant. Nitisinone was continued throughout pregnancy with a varying serum concentration and dose ranging from 0.8 to 1.4 mg/kg/day. Blood tyrosine remained stable until it increased in late pregnancy. α-fetoprotein increased to 284 μg/L without new changes in liver. Urine succinylacetone remained undetectable, but there were signs of possibly reoccurring kidney tubulopathy. Fetal ultrasound monitoring was normal throughout the pregnancy and the newborn healthy. After the delivery, α-fetoprotein normalized, but tyrosine continued to rise for up to 1 year. The child is developing normally. Conclusions Pregnancy during nitisinone was successful, but tailoring of the drug dose and possibly reappearing complications, as also increasing serum tyrosine concentration after delivery warranted intensified surveillance.

Abstract
OBJECTIVES To chart trends in the presentation of celiac disease in a large cohort of Finnish children diagnosed over a period of 48 years. STUDY DESIGN Clinical and serologic data, severity of small-bowel mucosal damage, and presence of associated conditions were gathered from 596 children diagnosed with celiac disease in 1966-2013. The children were divided into 4 groups based on the year of diagnosis (before 1980, 1980-1999, 2000-2009, and 2010-2013), and the variables were compared between the periods. The incidence of celiac disease autoimmunity in 2001-2013 was calculated based on the number of new antibody-positive cases in each year. RESULTS Age at diagnosis rose from median 4.3 years before 1980 to between 7.6 and 9.0 years in the later periods. The severity of clinical presentation, in general, became milder and poor growth less common during the entire study period of 50 years. Percentages of children with classical gastrointestinal presentation decreased, and those with atypical or subclinical presentation increased after the 1990s, these changes leveling off in 2000-2013. Similarly, the severity of small-bowel mucosal damage was milder after the 1990s. The incidence of celiac disease autoimmunity increased in the early 2000s but then fluctuated without a clear trend. There were no significant secular changes in sex distribution, presence of anemia, levels of celiac antibodies, or celiac disease-associated conditions. CONCLUSIONS The clinical and histologic presentation of celiac disease in children became milder, especially in the 1980s and 1990s. However, most of these changes have reached a plateau in recent years.

Abstract
We present a combined classification and reconstruction algorithm for diffuse optical tomography (DOT). DOT is a nonlinear ill-posed inverse problem. Therefore, some regularization is needed. We present a mixture of Gaussians prior, which regularizes the DOT reconstruction step. During each iteration, the parameters of a mixture model are estimated. These associate each reconstructed pixel with one of several classes based on the current estimate of the optical parameters. This classification is exploited to form a new prior distribution to regularize the reconstruction step and update the optical parameters. The algorithm can be described as an iteration between an optimization scheme with zeroth-order variable mean and variance Tikhonov regularization and an expectation-maximization scheme for estimation of the model parameters. We describe the algorithm in a general Bayesian framework. Results from simulated test cases and phantom measurements show that the algorithm enhances the contrast of the reconstructed images with good spatial accuracy. The probabilistic classifications of each image contain only a few misclassified pixels.

Abstract
The significance of accurate knowledge of background optical properties and time-resolved information in reconstructing images of hemodynamic changes in the neonatal brain from diffuse optical imaging data was studied using Monte Carlo (MC) simulation. A segmented anatomical magnetic resonance (MR) image and literature-derived optical properties for each tissue type were used to create a voxel-based anatomical model. Small absorbing perturbations were introduced into the anatomical model to simulate localized hemodynamic responses related to brain activation. Perturbation MC (pMC) was used as the primary method of image reconstruction. For comparison, reconstructions were also performed using the finite element method (FEM) to solve the diffusion approximation (DA) to the radiative transfer equation (RTE). The effect of optode layout was investigated using three different grids. Of the factors studied, the density of the optode grid was found to have the greatest effect on image quality. The use of time-resolved information significantly improved the spatial accuracy with all optode grids. Adequate knowledge and modeling of the optical properties of the background was found to significantly improve the spatial accuracy of the reconstructed images and make the recovery of contrast of absorption changes more consistent over simplified modeling. Localization accuracy of small perturbations was found to be 2-3 mm with accurate a priori knowledge of the background optical properties, when a grid with high optode density (>1 optode cm(-2)) was used.

Abstract
In diffuse optical tomography (DOT), the object with unknown optical properties is illuminated with near infrared light and the absorption and diffusion coefficient distributions of a body are estimated from the scattering and transmission data. The problem is notoriously ill-posed and complementary information concerning the optical properties needs to be used to counter-effect the ill-posedness. In this article, we propose an adaptive inhomogenous anisotropic smoothness regularization scheme that corresponds to the prior information that the unknown object has a blocky structure. The algorithm updates alternatingly the current estimate and the smoothness penalty functional, and it is demonstrated with simulated data that the algorithm is capable of locating well blocky inclusions. The dynamical range of the reconstruction is improved, compared to traditional smoothness regularization schemes, and the crosstalk between the diffusion and absorption images is clearly less. The algorithm is tested also with a three-dimensional phantom data.

Abstract
BACKGROUND To test the hypothesis that sufficient pain relief during delivery decreases the risk of postnatal depression. METHODS As part of a prospective follow-up study of the risk factors for postnatal depression and its impact on the mother-infant interaction and child development, 185 parturients filled in the Edinburgh Postnatal Depression Scale (EPDS), first during the first postpartum week and again (n = 162) 4 months later. The incidence and the risk of high EPDS scores was calculated according to the mode of delivery and the mode of pain relief during vaginal delivery, also after adjusting for the length of labor. RESULTS Mothers who received epidural/paracervical blockade during their delivery spent less time in the delivery room than mothers in the nitrous oxide/acupuncture group (p = 0.033) or mothers with no pain relief (p = 0.026) and had shorter length of labor than mothers without pain relief (p = 0.04). The adjusted risk of depressive scores at the first postnatal week was decreased in the epidural/paracervical group when compared with no analgesia group (OR: 0.25, 95% CI: 0.09-0.72). This difference was not shown at 4 months postpartum. Elective or emergency cesarean section did not increase the risk of high EPDS scores at the first week or at 4 months postpartum. CONCLUSION The mode of pain relief during vaginal delivery seems to be associated with the incidence of postpartum depression, especially immediately after delivery.

Abstract
BACKGROUND We evaluated the occurrence of postnatal depression in general and during different seasons as part of a larger longitudinal mother-child follow-up study. METHOD One hundred and eighty-five mothers, from the maternity wards of University Hospital of Oulu, Finland, completed a self-rating depression scale, the Edinburgh Postnatal Depression Scale (EPDS) twice: first at hospital 2-7 days after delivery and the second time at home 4 months after the delivery. Different psychosocial variables were mapped out to avoid any confounding factors. The year was divided in two separate ways: first, three different time periods were selected by the amount of sunlight: dark (October-January), intermediate (February, March, August, September) and light (April-July), and second, the year was divided by seasons. The results were analysed by the chi(2)-test for multinomials. RESULTS Sixteen percent (16.2) of mothers were scored as being depressed using 13 as a cut-off point immediately after the infant was born. Thirteen percent (13.0) were depressed measured 4 months postpartum. There was more mild depression in the autumn (ratio observed/expected 1,62; 95% confidence interval 1.05-2.19) immediately after delivery, using 10 as a cut-off, and less depression in the spring (0.27; 0.00-0.62) measured at home later, using 13 as a cut-off. When using classification by the amount of light there was more depression during the dark time (1.58; 1.05-2.11) immediately postpartum. LIMITATIONS The group sizes and the amount of sample sizes collected within each month are quite small. CONCLUSIONS It should be borne in mind that seasonal changes and alterations in the amount of light might influence the occurrence of postnatal depression.

Abstract
The prevalence of disability at the age of 75+ measured by the Katz Index of Activities of Daily Living (ADL) was compared among three birth cohorts: those born < or = 1903 (n = 348), those born < or = 1913 (n = 586), and those born < or = 1923 (n = 758). Significant risk factors for disability were female sex and age; the cohort effect was not significant. The prevalence rates of disability were 29.0% (95% CI 24.2-33.8), 34.8% (30.9-38.7), and 28.8% (25.5-32.0) for the first, second, and third cohorts. In the age group 75-79 years the rates were 20.1% (95% CI 13.8-26.4), 25.5% (20.2-30.7), and 14.4% (10.6-18.1). The change was due to the declining disability of women. The distributions in the three cohorts based on the numbers of ADL limitations did not differ. As far as the whole aged populations were concerned, longer life was not accompanied by improving health.

Abstract
OBJECTIVE To evaluate the domain-specific quality of life (QOL), including physical, social and role functioning, mental health, vitality, bodily pain, and general health domains, and to assess QOL's clinical and sociodemographic correlates in patients who were disabled by ischemic stroke. DESIGN One-year prospective study of an inception cohort of patients with first-ever brain infarction. SETTING Stroke unit of a neurologic department of a university hospital. PATIENTS Eighty-five consecutive patients (36 women, 49 men; mean age +/- SD, 65+/-12.5 yr) with first-ever stroke of a mild to moderate nature caused by brain infarction. MAIN OUTCOME MEASURES Patients were examined at 3 and 12 months poststroke. QOL was measured using the RAND 36-Item Health Survey. The variables studied were lateralization of cerebral lesion, neurologic and functional status, depression, age, gender, marital status, and living conditions. Depression was evaluated according to the criteria of Diagnostic and Statistical Manual of Mental Disorders, Revised Third Edition. Neurologic impairment was assessed by Scandinavian Stroke Scale, performance in activities of daily living by the Barthel index, and the intellectual deterioration by the Mini-Mental State Examination. RESULTS QOL was poorer for the patients with mild to moderate stroke impairments at 3 months poststroke. The test domains most prone to being affected were physical functioning, physical role limitations, vitality, and general health. Only the domains of physical functioning and physical role limitations improved during the follow-up at 1 year. Depression, although mostly minor, was the most important reason for impaired QOL. Depression, being married, and age emerged as significant independent contributors to the low score value of vitality. Depression and being married were related to the low score value of physical role limitations. CONCLUSIONS Stroke affects QOL, impairing its physical and psychosocial domains. The most important determinants of low QOL seem to be depression and being married. These findings provide new challenges for stroke rehabilitation, calling for identification of patients and spouses in need of supportive services.

Abstract
Aphasia, depression, and cognitive dysfunction are common consequences of stroke, but knowledge of their interrelationship is limited. This 1-year prospective study was designed to evaluate prevalence and course of post-stroke aphasia and to study its psychiatric, neurological, and cognitive correlates. We studied a series of 106 consecutive patients (46 women and 60 men, mean age 65. 8 years) with first-ever ischaemic brain infarction. The patients were clinically examined, and presence and type of aphasia were evaluated during the 1st week after stroke and 3 and 12 months later. Psychiatric and neuropsychological evaluations were performed 3 and 12 months after stroke. Aphasia was diagnosed in 34% of the patients during the acute phase, and two thirds of them remained so 12 months later. Seventy percent of the aphasic patients fulfilled the DSM-III-R criteria of depression 3 months and 62% 12 months after stroke. The prevalence of major depression increased from 11 to 33% during the 12-month follow-up period. The non-verbal neuropsychological test performance in the aphasic patients was significantly inferior to that of the patients with dominant hemisphere lesion without aphasia. One third of the patients with ischaemic stroke suffer from communicative disorders which seem to increase the risk of depression and non-verbal cognitive deficits. Although the prevalence of depression in aphasic patients decreases in the long term, the proportion of patients suffering from major depression seems to increase. We emphasize the importance of the multidimensional evaluation of aphasic stroke patients.

Abstract
OBJECTIVE Various degenerative cerebral diseases and even depression may cause abnormalities of the cognitive event related potentials (ERPs). We conducted the present study to elucidate the effects of ischemic stroke on the P300 ERP component. MATERIAL AND METHODS We recorded the P300 wave using an auditory oddball paradigm in 38 consecutive brain infarct patients with mild neurological deficits at 3 and 12 months post-stroke, and in 29 healthy control subjects. RESULTS Brain infarction slightly prolonged the P300 latency, and the observed delay was related to the presence and degree of post-stroke depression evaluated with the Zung Depression Scale and the DSM-III criteria. Infarction did not affect the P300 amplitude or its distribution on the scalp. The results of the patients with hemispheric brain infarction and those of the patients with brainstem infarction were similar, and also the values of the patients with the left- and right-sided lesions. The normal physiological correlation between subject age and the P300 latency was absent at 3 months post-stroke, but was present at 12 months post-stroke. CONCLUSION Brain infarction delays the P300 ERP and temporarily distorts its age-related physiology. The increase of the P300 latency seems to be associated with the post-stroke depression.

Abstract
BACKGROUND AND PURPOSE The prevalence of poststroke depression is known to be high, but the knowledge of its neuropsychological correlates is limited. This 12-month prospective study was designed to evaluate the natural history of poststroke depression and to study its neuropsychological, clinical, and functional associates. METHODS We studied a series of 106 consecutive patients (46 women and 60 men, mean age 65.8 years) with acute first-ever ischemic stroke. The patients underwent a neurological, psychiatric, and neuropsychological examination at 3 and 12 months after the stroke. The psychiatric diagnosis of depression was based on DSM-III-R-criteria. RESULTS Depression was diagnosed in 53% of the patients at 3 months and in 42% of the patients at 12 months after the stroke. The prevalence of major depression was 9% at 3 months and 16% at 12 months. There was an association between poststroke depression and cognitive impairment; the domains most likely to be defective in stroke-related depression were memory (P=0.022), nonverbal problem solving (P=0.039), and attention and psychomotor speed (P=0.020). The presence of dysphasia increased the risk of major depression. The depressive patients were more dependent in ADL and had more severe impairment and handicap than the nondepressive patients. CONCLUSIONS More than half of the patients suffer from depression after stroke, and the frequency of major depression seems to increase during the first year. In addition to dysphasia, poststroke depression is correlated with other cognitive deficits. We emphasize the importance of psychiatric evaluation of stroke patients.

Abstract
Decline in sexual activities caused by diseases or by medication affecting the functions of the central nervous system has often been described, but there are few reports on diseases or medications causing hypersexuality. Bilateral lesions of the temporal lobes may result in the Klüver-Bucy syndrome, symptoms of which include hypersexuality, excessive eating, and mood changes. In this article, the authors describe moclobemide-induced reversible hypersexuality, without other features of the Klüver-Bucy syndrome, in two patients with stroke and one patient with Parkinson's disease.

Abstract
The aim of this paper was to explore the factors necessitating psychiatric hospital care in a Finnish multi-centre study of general hospital in-patients referred for psychiatric consultation. The study group consisted of 1251 patients referred to psychiatric hospital (n = 181) and a comparison group (n = 1070) consisting of subjects who were not referred. Differences between groups were studied by univariate analysis. Logistic regression analysis was used both to assess the factors contributing to referral to psychiatric hospital and to create predictive models. The validity of the models was analysed by means of receiver operating characteristic (ROC) curves in an independent sample. Psychiatric hospital care during the previous 5 years was associated with a 3.7-fold (odds ratio) increased risk of hospitalization. A diagnosis of psychosis was associated with a 2.9-fold increased risk, and attempted suicide as a reason for consultation was associated with a 2.1-fold increased risk. Not being married doubled the risk, and the odds ratio was also high in cases of poor psychosocial functioning (as assessed by Global Assessment of Functioning (GAF) score). The predictive model differentiated reasonably well between those patients who were hospitalized and the other patients. In conclusion, this multi-centre study of factors predictive of referral to psychiatric hospital among general hospital patients revealed that the most important determinants were previous psychiatric care, diagnosis of psychosis or severe depression, attempted suicide, being unmarried, and poor psychosocial functioning as assessed by GAF score.

Abstract
A screening instrument based on the DSM-III-R was developed in order to differentiate aged persons with or without a DSM-III-R mental disorder. The usefulness of this instrument was investigated in six geriatric institutions with 171 residents aged 65 to 93 years in Finland. The nursing staff independently rated the mental status of residents; researchers (a psychiatrist and general practitioner) made a diagnosis based on DSM-III-R criteria. The majority of the residents (mean 69%, varying from 33% to 84% in different institutions) had a DSM-III-R mental disorder. This screening instrument functioned well in differentiating residents without a mental disorder from those with DSM-III-R mental disorder: The nursing staff's agreement was 90%, kappa.71, sensitivity .90, and specificity .88. However, only half the cases of depression were diagnosed correctly: Sensitivity was .50 and specificity .95. With a more specific 9-class diagnostic instrument based mainly on DSM-III-R categories, agreement was only moderate (68%) and kappa .59. The instrument developed in this study seemed to be a useful screening method when applied by the staff, but accurate diagnostics require psychiatric knowledge, especially of depression.
