RESUMEN
PURPOSE: The study aimed to investigate associations between maternal vitamin D status during pregnancy and molar incisor hypomineralisation (MIH) and hypomineralised second primary molars (HSPM) among children. METHODS: The study had a longitudinal design using prospectively collected data from 176 mother and child pairs. Mothers were initially recruited in a randomised controlled trial to assess a pregnancy exercise programme. Along with the 7-year follow-up, we invited the children to a dental examination. The exposure variable was maternal serum 25-hydroxyvitamin D in gestational weeks 18-22 and 32-36, categorised as insufficient (< 50 nmol/l) and sufficient (≥ 50 nmol/l). Negative binomial hurdle models were used to analyse potential associations between the exposure variables and MIH or HSPM. The models were adjusted for potential confounders. RESULTS: Among the children (7-9 years old), 32% and 22% had at least one tooth with MIH or HSPM, respectively. A significant association was found between insufficient maternal vitamin D measured in gestational weeks 18-22 and the number of affected teeth among those with MIH at 7-9 years (adjusted RR = 1.82, 95% CI 1.13-2.93). CONCLUSION: Considering any limitations of the present study, it has been shown that insufficient maternal serum vitamin D at mid-pregnancy was associated with a higher number of affected teeth among the offspring with MIH at 7-9 years of age. Further prospective studies are needed to investigate whether this finding is replicable and to clarify the role of maternal vitamin D status during pregnancy and MIH, as well as HSPM, in children.

BACKGROUND: Colorectal cancer (CRC) is the third most common cancer worldwide, and a large proportion of the patients receive adjuvant oxaliplatin-based chemotherapy. Most of these experience chemotherapy-induced peripheral neuropathy (CIPN), affecting quality of life. Evidence to advise exercise to reduce CIPN is limited. The primary aim of this study was to investigate the feasibility of an exercise intervention and data collection among CRC patients during adjuvant chemotherapy. MATERIAL AND METHODS: This non-randomized feasibility study included CRC patients admitted to adjuvant chemotherapy to an intervention consisting of supervised aerobic endurance, resistance, and balance exercises twice a week at the hospital in addition to home-based exercise once a week. A physiotherapist supervised the patients, and the intervention lasted throughout the period of adjuvant chemotherapy (12-24 weeks). Participants performed physical tests and filled in questionnaires at baseline, 3, 6, 9, and 12 months. RESULTS AND CONCLUSION: Nineteen (63%) of 30 invited patients consented. A major barrier to recruit or consent to participation was long travel distance to the hospital. The completion rate of questionnaires and physical tests were near 100%. Seven participants dropped out, five before the intervention started. Median attendance to supervised exercise was 85%. There were no serious adverse events related to the intervention. Except for a planned higher intensity of endurance exercise, we found the intervention feasible and safe. Based on experiences in this study, some adjustments have been made for an upcoming randomized trial, including the supervised exercise taking place close to participants' homes. TRIAL REGISTRATION: NCT03885817, March 22, 2019, retrospectively registered.

OBJECTIVE: To assess the association between levels of vitamin D and urinary incontinence (UI) in pregnancy. DESIGN: A cross-sectional study. Secondary analysis of a randomised controlled trial. SETTING: Two university hospitals in Norway. POPULATION: A total of 851 healthy, pregnant women >18 years in gestational weeks 18-22 with a singleton live fetus. METHODS: Data on UI were collected from a questionnaire at inclusion and serum analysis of 25-hydroxy vitamin D (25(OH)D) was performed. Univariable and multivariable logistic regression analyses were applied to study associations between exposure and outcomes. MAIN OUTCOME MEASURES: Prevalence of self-reported UI, stress (SUI) and urge (UUI) or mixed UI. RESULTS: In total, 230/851 (27%) of the participants were vitamin D insufficient (25(OH)D <50 nmol/l) and 42% reported to have any UI. Women with 25(OH)D <50 nmol/l were more likely to report any UI (P = 0.03) and SUI (P < 0.01) compared with women with 25(OH)D ≥50 nmol/l. In a univariable logistic regression analysis, serum levels of 25(OH)D <50 nmol/l was associated with increased risk of any UI (odds ratio [OR] 1.5 with 95% CI 1.0-2.1), SUI only (OR 1.7, 95% CI 1.2-2.4), but not mixed UI or UUI only (OR 0.8, 95% CI 0.5-1.5). In a multivariable logistic regression model, serum levels of 25(OH)D <50 nmol/l were associated with a higher risk of experiencing SUI only (OR 1.5, 95% CI 1.1-2.2). CONCLUSIONS: Serum 25(OH)D <50 nmol/l was associated with increased risk of any UI, and SUI in particular. TWEETABLE ABSTRACT: Low levels of vitamin D are associated with increased risk of urinary incontinence in pregnancy.

OBJECTIVE: To investigate whether regular moderate intensity exercise during pregnancy had adverse effect on neurodevelopment of offspring at 7 years of age. DESIGN: Follow up of a multicentre randomised controlled trial. SETTING: St Olavs Hospital, Trondheim University Hospital and Stavanger University Hospital, Norway (2007-09). POPULATION: Women randomised to follow a 12-week structured exercise protocol or standard antenatal care during pregnancy. METHODS: At 7 years of age, neurodevelopmental outcome was assessed by the parent questionnaire Five-To-Fifteen (FTF), including motor skills, executive functions, perception, memory, language, social skills and possible emotional/behavioural problems. MAIN OUTCOME MEASURE: Continuous and dichotomised (cut-off 90th centile) FTF scores. RESULTS: A total of 855 women were randomised to exercise (n = 429) or standard antenatal care (n = 426) during pregnancy. At follow up, 164 (38.2%) children born to mothers in the intervention group and 115 (27.0%) children born to mothers in the control group participated. We found no group differences in FTF scores or in the proportion of children with scores ≥90th centile. Stratified analyses by sex, subgroup analyses of women who adhered to the exercise protocol or sensitivity analyses excluding preterm children and/or children who had been admitted to the neonatal intensive care unit did not change the results. CONCLUSIONS: In the present randomised controlled trial follow-up study, regular moderate intensity exercise during pregnancy did not have adverse effect on neurodevelopment of offspring at 7 years of age. TWEETABLE ABSTRACT: Moderate intensity exercise during pregnancy had no adverse effect on neurodevelopment of offspring at 7 years of age.

OBJECTIVE: To develop maternal, fetal, and neonatal composite outcomes relevant to the evaluation of diet and lifestyle interventions in pregnancy by individual patient data (IPD) meta-analysis. DESIGN: Delphi survey. SETTING: The International Weight Management in Pregnancy (i-WIP) collaborative network. Sample Twenty-six researchers from the i-WIP collaborative network from 11 countries. METHODS: A two-generational Delphi survey involving members of the i-WIP collaborative network (26 members in 11 countries) was undertaken to prioritise the individual outcomes for their importance in clinical care. The final components of the composite outcomes were identified using pre-specified criteria. MAIN OUTCOME MEASURES: Composite outcomes considered to be important for the evaluation of the effect of diet and lifestyle in pregnancy. RESULTS: Of the 36 maternal outcomes, nine were prioritised and the following were included in the final composite: pre-eclampsia or pregnancy-induced hypertension, gestational diabetes mellitus (GDM), elective or emergency caesarean section, and preterm delivery. Of the 27 fetal and neonatal outcomes, nine were further evaluated, with the final composite consisting of intrauterine death, small for gestational age, large for gestational age, and admission to a neonatal intensive care unit (NICU). CONCLUSIONS: Our work has identified the components of maternal, fetal, and neonatal composite outcomes required for the assessment of diet and lifestyle interventions in pregnancy by IPD meta-analysis.

OBJECTIVE: To investigate whether a customised exercise programme influences pregnant women's psychological wellbeing and general health perception reflecting health-related quality of life (HRQoL) in late pregnancy. DESIGN: A two-armed, two-centred randomised controlled trial. SETTING: Trondheim and Stavanger University Hospitals, Norway. POPULATION: A total of 855 healthy Caucasian pregnant women. METHODS: The intervention group was offered a 12-week exercise programme between 20 and 36 weeks of pregnancy. One weekly group session was led by physiotherapists, in addition women were encouraged to follow a home exercise programme at least twice a week. The exercise programme followed standard recommendations and included both aerobic and strength training. The control group received regular antenatal care. Pretests and post-tests were performed at 18-22 and 32-36 weeks of pregnancy. MAIN OUTCOME MEASURES: In the original study primary outcome was gestational diabetes mellitus, but in this report the primary outcome is HRQoL. The questionnaire Psychological General Wellbeing Index (PGWBI) was used to assess psychological wellbeing and self-perceived general health before and after the intervention. PGWBI contains six subscales and it is also possible to summarise all items to a global score. RESULTS: No association between antenatal exercise programme allocation and PGWBI (global score and subscales) was found. The study population was homogeneous and had high educational level. CONCLUSIONS: The results indicate that offering women an exercise programme during pregnancy does not seem to influence healthy pregnant women's psychological wellbeing and self-perceived general health. Further research is needed to investigate the effects of exercise in pregnancy on psychological wellbeing and self-perceived general health among women from different sociocultural subgroups. TWEETABLE ABSTRACT: Exercise in pregnancy does not influence healthy pregnant women's health-related quality of life.

INTRODUCTION: Some pregnancy complications are characterized by increased levels of cell-free fetal (cffDNA) and maternal DNA (cfmDNA), the latter may also be elevated during physical strain. This study aims at assessing the impact of exercise and metformin intervention in pregnancy, and to compare the levels of cell free DNA in pregnant women with or without PCOS diagnosis. METHODS: Consecutive women from two previous randomized controlled trials in pregnancy were included. Women came from a trial with organized exercise vs. standard antenatal care in pregnancy and a trial of metformin vs. placebo in PCOS women. Levels of cffDNA, cfmDNA and cell-free total DNA (cftDNA) were measured by qPCR. RESULTS: Training in pregnancy did not affect the levels of cffDNA, cfmDNA or cftDNA. PCOS-women treated with metformin had lower levels of cfmDNA and cftDNA at week 32 (mean ± SD: 301 ± 162 versus 570 ± 337, p = 0.012, 345 ± 173 versus 635 ± 370, p = 0.019); otherwise the levels were comparable to PCOS-controls. Metformin-treated PCOS-women had higher cffDNA at inclusion, in the 1st trimester; later on in pregnancy the levels in the metformin and placebo groups were equal. A comparison of pregnant women in the exercise study (TRIP) to placebo-treated pregnant PCOS-women, showed the levels of cffDNA, cfmDNA or cftDNA during mid-pregnancy (weeks 18-36) to be equal. DISCUSSION: Training during pregnancy was not associated with altered levels of cffDNA cfmDNA or cftDNA, but metformin treatment may reduce cfmDNA and cftDNA in pregnant PCOS women.

OBJECTIVE: To assess whether pregnant women following a general exercise course, including pelvic floor muscle training (PFMT), were less likely to report urinary and anal incontinence in late pregnancy than a group of women receiving standard care. DESIGN: A two-armed, two-centred randomised controlled trial. SETTING: Trondheim University Hospital (St. Olavs Hospital) and Stavanger University Hospital, in Norway. POPULATION: A total of 855 women were included in this trial. METHODS: The intervention was a 12-week exercise programme, including PFMT, conducted between 20 and 36 weeks of gestation. One weekly group session was led by physiotherapists, and home exercises were encouraged at least twice a week. Controls received regular antenatal care. MAIN OUTCOME MEASURES: Self-reported urinary and anal incontinence after the intervention period (at 32-36 weeks of gestation). RESULTS: Fewer women in the intervention group reported any weekly urinary incontinence (11 versus 19%, P = 0.004). Fewer women in the intervention group reported faecal incontinence (3 versus 5%), but this difference was not statistically significant (P = 0.18). CONCLUSIONS: The present trial indicates that pregnant women should exercise, and in particular do PFMT, to prevent and treat urinary incontinence in late pregnancy. Thorough instruction is important, and specific pelvic floor muscle exercises should be included in exercise classes for pregnant women. The preventive effect of PFMT on anal incontinence should be explored in future trials.
