Aim: To investigate the blood pressure (BP) and ductal calibre patterns associated with early ductal closure in very low gestational age (<32 weeks) infants.

Methods: Blood pressure was continuously measured intra-arterially among 43 infants participating in a randomised, double-blind trial of 4 days prophylactic intravenous paracetamol. Early closure of the ductus was verified by daily ultrasound examinations.

Background: There is limited data on the organisation of paediatric echocardiography laboratories in Europe.

Methods: A structured and approved questionnaire was circulated across all 95 Association for European Paediatric and Congenital Cardiology affiliated centres. The aims were to evaluate: (1) facilities in paediatric echocardiography laboratories across Europe, (2) accredited laboratories, (3) medical/paramedical staff employed, (4) time for echocardiographic studies and reporting, and (5) training, teaching, quality improvement, and research programs.

Prematurity has been associated with impaired parasympathetic cardiac regulation later in life. Changes in heart rate (HR) and heart rate variability (HRV) may indicate a risk for future cardiac dysfunction. The putative role of Vitamin D on cardiac autonomic function in individuals born preterm (PT) remains unknown.

Prematurity has been linked to lower muscular fitness and increased morbidity across the human lifespan. Hand grip strength is widely used as a measure of muscle strength. Previous studies have shown inconsistent results regarding the role of vitamin D in hand grip strength.

Antiarrhythmic medication (AM) is commonly used to prevent supraventricular tachycardia (SVT) recurrence in infants. Our aim was to determine whether a shorter duration of AM is sufficient to prevent atrioventricular reentrant tachycardia (AVRT) recurrence and evaluate risk factors for recurrence of SVT after discontinued AM.This multicenter cohort study included all infants diagnosed with SVT in the five university hospitals in Finland between 2005 and 2017.

Background: Paracetamol promotes early closure of patent ductus arteriosus (PDA), and it may affect inflammation after preterm birth.

Objective: The aim of this study was to evaluate the association between paracetamol treatment and serum inflammatory biomarkers in very preterm infants with respiratory distress.

Study Design: The infants were randomly assigned to intravenous paracetamol or placebo during the first 4 days of life, and others received a lower dose of paracetamol unblinded.

This study examined the malleability of math self-efficacy (SE) among children with poor calculation fluency via an intervention that targeted four sources of SE (mastery experiences, vicarious experiences, social persuasions, and emotional and physiological states). The effect of pure strategy training was contrasted with an intervention that integrated strategy training and explicit SE support. Moreover, the changes in SE source experiences and their relation with math SE, as well as the relation between math-SE profiles and calculation fluency development, were examined.

Background/aim: Our phase III trial showed that biweekly docetaxel (D) is better tolerated than triweekly D in metastatic castration-resistant prostate cancer (mCRPC). The safety of biweekly cabazitaxel (CBZ) post-docetaxel was studied in mCRPC.

Patients And Methods: Altogether, 60 patients received CBZ 16 mg/m i.

Background: We previously reported in a randomised trial that early intravenous paracetamol accelerated contraction of ductus arteriosus in very preterm infants (<32 gestation weeks).

Aims: To monitor sequentially paracetamol effects on the blood pressure and brain tissue oxygenation in the infants participating the trial.

Methods: In a double-blind trial, intravenous paracetamol or placebo was infused to 48 very premature infants starting within 24 h of birth for four days.

Background: Docetaxel combined with androgen deprivation therapy (ADT) has improved patient survival for advanced prostate cancer (PCa).

Objective: This randomised trial aimed to evaluate whether six courses of docetaxel improved biochemical disease-free survival (BDFS) after radical radiotherapy (RT) for intermediate- or high-risk PCa patients.

Design, Setting, And Participants: A total of 376 patients were randomised in this multinational phase III study, and received either six cycles of adjuvant docetaxel 75 mg/m every 3 wk without continuous prednisone (arm A, n = 188) or surveillance (arm B, n = 188) after RT (NTC006653848).

This study examined the subjective quality of life among youth with severe physical disabilities during the transition to adulthood. A purposive sample of 74 youths (mean age 20.19) with severe physical disabilities completed World Health Organization Quality of Life - Brèf (WHOQOL-BREF) to measure the quality of life; the Severely Disabled Youths' Life Situation and Functioning of Service Systems in Finland to measure health issues.

To evaluate the performance of first trimester biochemical markers, pregnancy-associated plasma protein-A (PAPP-A), free beta human chorionic gonadotropin (fβ-hCG), and nuchal translucency (NT) in detection of severe congenital heart defects (CHDs). During the study period from 1 January 2008 to 31 December 2011, biochemical markers and NT were measured in 31,144 women as part of voluntary first trimester screening program for Down's syndrome in Northern Finland. Data for 71 severe CHD cases and 762 controls were obtained from the hospital records and from the National Medical Birth Register, which records the birth of all liveborn and stillborn infants, and from the National Register of Congenital Malformations that receives information about all the CHD cases diagnosed in Finland.

Objective: To evaluate the performance of first-trimester measurement of fetal nuchal translucency (NT) in the detection of severe congenital heart defects (CHDs).

Methods: During the study period of 1 January 2008 - 31 December 2011, NT was measured in 31,144 women as a part of voluntary first-trimester screening program for Down's syndrome in Northern Finland. NT was measured by personnel trained on the job by the experienced staff.

Objective: To study the biologic effect of paracetamol, an inhibitor of prostaglandin synthase, on early closure of ductus arteriosus, and to evaluate possible adverse effects associated with the drug.

Study Design: In a controlled, double-blind, phase I-II trial, very low gestational age (<32 weeks) infants requiring intensive care were randomly assigned to intravenous paracetamol or placebo (0.45% NaCl).

Background: Patients with non-muscle-invasive bladder cancer (NMIBC) belonging to the intermediate-risk group should be treated with intravesical instillations to prevent recurrence and progression.

Objective: We compared the outcome of a monthly maintenance bacillus Calmette-Guérin (BCG) regimen with that of epirubicin (EPI) and interferon-α2a (IFN) in patients with NMIBC.

Design, Setting, And Participants: Our prospective randomized multicenter study comprised 229 eligible patients with frequently recurrent TaT1 grade 1-2 or low-grade NMIBC enrolled between 1997 and 2008.

Aim: Neonatal therapy-resistant septic shock is a common problem in middle and low-income countries. We investigated whether newborn infants with infection and therapy-resistant hypotension showed evidence of abnormal levels of cortisol or cortisol precursors.

Methods: A total of 60 term or near term neonates with evidence of infection were enrolled after informed consent.

Prostatic pain usually refers to male chronic pelvic pain syndrome (CPPS), chronic abacterial prostatitis. It has a prevalence of 14% among Finnish men, and it is characterised by chronic pain in the pelvis, genital and inguinal area, lower abdomen and perineum, often accompanied by various urinary symptoms. The aetiology and pathophysiology of CPPS are poorly understood.

GPs often encounter patients with scrotal masses. Most of these are easily diagnosed by means of palpation and transillumination. Scrotal ultrasound is the primary radiological investigation, and should be done in cases of uncertain clinical diagnosis or when a solid mass in the scrotum is suspected.

Background: The aim of the study was to evaluate the safety and reliability of automatic ventricular pacing threshold measurement, the Medtronic Capture Management (CM), in children with epicardial pacing leads. CM has not been recommended for use with epicardial leads due to lack of pertinent data.

Methods: During a 2-year study period, 34 children (mean age 6.
