To evaluate the long-term results at the donor site in children who underwent harvesting of autogenous fascia lata for frontalis suspension in ptosis correction. The study design consists of a retrospective, nonrandomized case series. Medical records of 30 patients were reviewed. Each patient was reexamined, evaluating bulging at the donor site. Muscle prolapse was graded as not visible and not palpable, not visible but palpable, mildly visible, or obviously visible. Measurement of the width and length of the leg scar was recorded. Discomfort at the donor site was graded as no discomfort, occasional discomfort, or frequent discomfort. The mean age of the patients was 7 years (range, 1-15), with a mean follow-up period of 27 months (range, 3-63 months). Fifteen patients (50%) had invisible and impalpable bulging, 2 patients (6.7%) had invisible but palpable bulging, 5 patients (16.7%) had mildly visible bulging, and 8 patients (26.7%) had obviously visible bulging. The mean width of the scar was 7.5 mm, and the mean length was 3.6 cm. Twenty-seven patients (90%) had no functional discomfort of the leg, 2 patients (6.7%) had occasional discomfort, and 1 patient (3.3%) had frequent discomfort that occurred during exercise. After fascia lata harvesting, most patients had no cosmetic complaints or functional complications. The technique of harvesting fascia lata using a Crawford stripper seems to be safe and satisfactory.

Background: Preconception lifestyle interventions appear promising to reduce pregnancy complications, prevent adult cardiometabolic diseases, and prevent childhood obesity. These interventions have almost exclusively been studied in populations of obese infertile women. The development of preconception lifestyle interventions targeting a broader population of overweight and obese women without a history infertility and their partners is needed.Methods: This study is a multicenter open label parallel group randomized controlled trial. Sixty-eight non-infertile women with overweight or obesity in the preconception period and their partners will be recruited from the Sherbrooke and Quebec City regions. The couples will be randomized in a 1:1 ratio to receive the Healthy for my Baby intervention or standard care in the preconception period and pregnancy. Women and their partners will be invited to take part in this lifestyle intervention which includes motivational interviews and daily self-monitoring of lifestyle goals through a mobile phone application. The primary endpoint of this study is the diet quality of women during the preconception period, which will be evaluated using the C-HEI 2007 score at baseline, 2, 4- and 6-months following study enrolment. Women's dietary quality will also be evaluated through the measure of urinary biomarkers of habitual dietary intake at baseline and 2 months in preconception, and 24–26 weeks in pregnancy. Additional indicators of women's lifestyle as well as anthropometric measures will be documented in preconception and pregnancy. For the pregnancy period, the main secondary endpoint is the pattern of gestational weight gain. Pregnancy and neonatal complications will also be evaluated. For partners, diet quality, other lifestyle habits, and anthropometric measures will be documented in the preconception and pregnancy periods.Discussion: This study will evaluate the effectiveness of a low-cost intervention designed to improve diet and other lifestyle characteristics of women in the preconception period who are overweight or obese. If the Healthy for my Baby intervention is efficacious regarding dietary measures, larger trials will be needed to evaluate the impact of this intervention on the rates of pregnancy complications, childhood obesity, and adult cardiometabolic disease.Clinical Trial Registration:clinicaltrials.gov (NCT04242069).

Objective: To comprehensively evaluate the interaction between diet quality and multivitamin intake during pregnancy on offspring neurodevelopment. Methods: This analysis was grounded in mother-child dyads from the 3D Cohort Study in Quebec, Canada. Among the 2366 participants initially enrolled in the 3D study, 1535 women successfully completed the 3-day food record during 20–24 weeks of gestation. A Canadian adaptation of the Healthy Eating Index (HEI-C) 2010 was used to quantify diet quality. The total HEI-C score was dichotomized into low and high diet quality by median split. Cognitive and motor development in childhood were assessed using the Bayley Scales of Infant and Toddler Development, Third Edition (Bayley-III). Language abilities were measured using the toddler short-form version of the MacArthur–Bates Communicative Development Inventories (MCDI) questionnaire, administered in either English or French. After excluding participants with missing covariate data, cognitive, motor, and language development scores at 2 years of age were available for 1066, 1040, and 981 children, respectively. Multiple linear regression models were employed to calculate adjusted effect estimates. The interaction on an additive scale was assessed by incorporating a product term into the linear regression model. Results: Statistically significant interactions were detected between diet quality and multivitamin intake in relation to the cognitive and language development outcomes of the offspring (interaction p-values were 0.018 and 0.023, respectively). The lowest cognitive and language scores were observed in the group of women who neither took multivitamins nor maintained a high-quality diet. Among women not taking multivitamins, a high-quality diet was associated with improved offspring cognitive and language scores (mean difference [95% CI] = 4.2 [0.1, 8.2], p = 0.04; and 11.3 [3.1, 19.5], p = 0.01, respectively). However, among women taking multivitamins, no such associations were identified. Conversely, in participants with a low-quality diet, multivitamin intake was associated with a 3.0-point increase in cognitive composite scores (95% CI: 0.3, 5.8, p = 0.03), but this was not the case for those with a high-quality diet. No statistically significant interactions were observed between maternal diet quality and multivitamin intake for motor development outcomes. Conclusions: Adequate nutritional supply during pregnancy, achieved either through a high-quality diet or multivitamin supplementation, is fundamental for the neurodevelopment of children.

Introduction: Inappropriate gestational weight gain (GWG), including inadequate and excessive GWG, has become pandemic across nations and continents. This review aims to synthesise the evidence on the correlation between diet quality and GWG. If this association is confirmed, improving diet quality could become an intervention target in the efforts to reduce inappropriate GWG. Methods and analysis: We will conduct a systematic review of all prospective cohort studies on diet quality in preconception or pregnancy and GWG. Our secondary outcomes include gestational diabetes, pre-eclampsia and birth weight. A comprehensive search of all published articles in MEDLINE ALL (Ovid), Embase (Ovid), Food Science and Technology Abstracts (Ovid) and CINAHL (EBSCOHost), from database creation to 20 April 2019, will be conducted. Studies will be screened for eligibility by title, abstract and full text in duplicate by two independent reviewers. Study quality and risk of bias will be assessed using the adapted Newcastle–Ottawa Scale. Results will be reported following the meta-analysis of observational studies in epidemiology guidelines. If sufficient data are available, a meta-analysis will be conducted to synthesise the effect size reported as OR with 95% CI using both fixed-effect and random-effect models. I 2 statistics and visual inspection of the forest plots will be used to assess heterogeneity and identify the potential sources of heterogeneity. Publication bias will be assessed by visual inspections of funnel plots and Egger’s test. Ethics and dissemination: Formal ethical approval is not required as no primary data will be collected. We aim to publish the results of this study in a peer-reviewed journal and present them at conferences and scientific meetings to promote knowledge transfer.

Nearly 20% of women will be confronted with anxiety or depressive disorders during the perinatal period and this may lead to adverse outcomes for both mother and child. Cognitive behavioural therapy (CBT) is the psychological intervention with the most empirical support for the clinical management of anxiety and depressive disorders. Anxiety and depression frequently occur in women during the perinatal period, and there is growing evidence that internet-delivered CBT (iCBT) could be an acceptable and effective intervention. THIS WAY UP, an Australian digital mental health service, has developed a program for postnatal anxiety and depression. This study protocol aims to examine the acceptability and efficacy of a French-Canadian adaptation of the program. The research team propose to conduct a mixed hybrid type 1 pragmatic randomized clinical trial and implementation study to replicate the findings of the trial conducted in Australia by Loughnan et al. (2019), as well as explore barriers and facilitators to potential large-scale implementation. TREATMENT AND CONTROL CONDITIONS: a) postnatal anxiety and depression iCBT program with three lessons to complete in a six-week period, added to treatment-as-usual (TAU); b) TAU. Participants will include French-speaking women with probable postnatal depression or anxiety as per the Generalized Anxiety Disorder-7 (GAD-7) or the Edinburgh Postnatal Depression Scale (EPDS). The primary outcome measures will be the GAD-7 and the EPDS. Secondary outcome measures will comprise self-reported instruments to evaluate psychological distress, quality of life, mother-child experience, and treatment experience. Qualitative interviews with participants and health professionals will provide insights on acceptability and delivery of the iCBT program. Statistical analysis will follow intent-to-treat principles. A mixed model regression approach will be used to account for between- and within-subject variations in the analysis of the effects of iCBT compared to TAU only intervention. The study will generate important data of efficacy and acceptability to patients, clinicians, and decision-makers to inform the scaling-up of the postnatal iCBT intervention in Canada.
