Childhood-onset inflammatory bowel disease and chronic non-bacterial osteomyelitis: A Swedish nationwide cohort study 2002-2022.

Background And Aims: Nationwide, population-based studies of chronic non-bacterial osteomyelitis (CNO) in patients with childhood-onset inflammatory bowel disease (IBD) are lacking.

Methods: We used nationwide registers to identify all children in Sweden diagnosed with IBD during 2002-2022 and the occurrence of CNO in this IBD cohort and general population non-IBD comparators. To estimate the temporal associations between IBD and CNO we used Cox regression.

Heterogeneity of reduced FEV in early adulthood: A looking forward, looking backwards analysis.

Background: Some individuals never achieve normal peak FEV in early adulthood. It is unknown if this is due to airflow limitation and/or lung restriction.

Methods: To investigate this, we: (1) looked forward in 19,791 participants in the Dutch Lifelines general population cohort aged 25-35 years with 5-year follow-up; and (2) looked backwards in 2032 participants in the Swedish BAMSE birth cohort with spirometry at 24 years of age but also at 16 and/or 8 years.

Modified Crohn's Disease Exclusion Diet Maintains Remission in Pediatric Crohn's Disease; Randomized Controlled Trial.

Background & Aims: The Crohn's Disease (CD) Exclusion Diet (CDED)+Partial Enteral Nutrition (PEN) is effective for inducing remission in mild-moderate CD. We assessed whether a 2-week course of Exclusive Enteral Nutrition (EEN), followed by CDED+PEN is superior to 8 weeks of EEN in sustaining clinical remission at week 14 in mild-to-severe CD and if CDED+PEN can maintain remission to week 24.

Methods: This international, multicenter, randomized-controlled trial compared 2-weeks of EEN (Modulen®IBD) followed by 3 phases of the CDED+PEN (henceforth CDED) to 8 weeks of EEN, followed by PEN with free diet up to week 24 (henceforth EEN).

Motor predictors of cortical brain development and full-IQ in children born extremely preterm with and without discrete white matter abnormalities.

Aim: To describe the cortical brain development and full-IQ performance in middle school age children after extremely preterm (EPT) birth considering discrete white matter abnormalities (WMA). In addition, to assess possible early motor predictors of cortical brain development and full-IQ in children born EPT with and without discrete WMA diagnosed at 10 years.

Methods: T1-weighted MRI images from fifty-one children born before 27 weeks' gestation and 40 full-term born controls (M=10.

Childhood lung function is associated with adolescent-onset and persistent asthma.

Background: Asthma is associated with impaired lung function; however, it is uncertain if a lower childhood lung function is associated with asthma onset and persistence during adolescence. The aims of the present study were to investigate the association between childhood lung function and onset and persistence of asthma during adolescence.

Methods: In the population-based BAMSE (Sweden), PIAMA (Netherlands) and MAAS (UK) birth cohorts, we analysed the association of forced expiratory volume in 1 s (FEV), forced vital capacity (FVC), FEV/FVC and forced expiratory volume at 75% of FVC at age 8 years with asthma onset and persistence in adolescence (age 12-16 years) using cohort-specific logistic regression analysis followed by meta-analysis.

Schools of public health as a cornerstone for pandemic preparedness and response: the Africa COVID-19 experience.

Background: The Coronavirus disease (COVID-19) pandemic caused significant morbidity and mortality in Africa, in addition to other socio-economic consequences. Across the continent, Schools of Public Health (SPHs) played several roles in supporting national, regional, and global response to the pandemic. Following a published and grey literature search, this paper reviews and analyses the contribution of SPHs in Africa during the COVID-19 pandemic.

Snus and cardiometabolic health markers among Swedish young adults.

Introduction: Snus is suggested as a risk factor for cardiometabolic disease, but little is known about health effects in young populations, particularly in women. We aimed to investigate associations between snus and cardiometabolic health markers among young men and women.

Method: This study was conducted within the BAMSE birth cohort and included participants followed up around 24 years (n=2256) and 26 years (n=1011).

Depression in childhood to early adulthood and respiratory health in early adulthood.

Background: Both depression and respiratory disease are common today in young populations. However, little is known about the relationship between them.

Aims: This study aims to explore the association between depression in childhood to early adulthood and respiratory health outcomes in early adulthood, and the potential underlying mechanisms.

Respiratory support and bronchopulmonary dysplasia in infants born at 22-26 weeks gestation in Sweden, 2004-2007 and 2014-2016.

Aim: To evaluate if increased survival and new ventilation strategies were accompanied by a changed incidence of bronchopulmonary dysplasia (BPD) in Sweden over a decade.

Methods: Data from two Swedish population-based studies of live-born infants with gestational ages (GA) 22-26 weeks, born during 2004-2007 (n=702) and 2014-2016 (n=885), were compared for survival, any BPD, moderate BPD, severe BPD, and BPD/severe BPD or death at 36 weeks postmenstrual age (PMA). Ventilation strategies and interventions were analysed.

BMI trajectories from birth to young adulthood associate with distinct cardiometabolic profiles.

Background: Numerous studies have investigated links between body mass index (BMI) trajectories and cardiovascular risk, yet discrepancies in BMI measurement duration and timing of the cardiovascular-related outcome evaluation have led to inconsistent findings.

Methods: We included participants from the Swedish birth cohort (BAMSE) and applied latent class mixture modeling to identify BMI trajectories using data of multiple BMI measures (≥ 4 times) from birth until 24-year follow-up (n = 3204). Subsequently, we analyzed the associations of BMI trajectories with lipids (n = 1974), blood pressure (n = 2022), HbA1c (n = 941), and blood leukocytes (n = 1973) using linear regression.

Labour market participation and income in patients with IBD onset before young adulthood - the role of disease severity and mental health.

Background And Aim: Only few studies have examined the socioeconomic consequences of being diagnosed with inflammatory bowel disease (IBD) in childhood or youth. Disease severity has been linked to lower earnings, but little attention has been paid to comorbid mental health conditions. The aim is to examine labour market participation (LMP) and income in patients with IBD-onset in childhood or youth and examine how disease severity and mental health conditions affects LMP.

EAACI guidelines on the management of IgE-mediated food allergy.

This European Academy of Allergy and Clinical Immunology (EAACI) guideline provides recommendations for the management of IgE-mediated food allergy and was developed using the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) approach. Following the confirmation of IgE-mediated food allergy diagnosis, allergen avoidance and dietary advice (with support of a specialised dietitian, if possible) together with the provision of a written treatment plan, education on the recognition of allergic symptoms and prescription of medication including adrenaline using an auto-injector are essential. Patients with significant anxiety and requirement for coping strategies may benefit from support from a clinical psychologist.

Body mass index trajectories from birth to early adulthood and lung function development.

Background: Few studies have investigated the influence of body mass index (BMI) trajectories on lung function covering the entire growth period.

Methods: We conducted a prospective study using data from the Swedish BAMSE birth cohort. Latent class mixture modelling was employed to examine the diversity in BMI z-scores from birth to 24 years of age.

If the first child is breech, overall outcomes for families with two children are similar regardless of the mode of the first birth.

Cesarean section for breech presentation is often recommended. However, cesarean section affects future reproduction. The aim of this study was to assess the effect of mode of the first birth in breech on outcomes of the second birth and the two births together.

Sociodemographic determinants of COVID-19 vaccination in adolescents in Stockholm, Sweden.

Introduction: Limited data exists on sociodemographic differences in vaccination coverage against COVID-19 among adolescents.
