Pregnancy Women and Individual Oral Prophylaxis in the Control of Gingival Inflammation (PRE-IOP)

Gingivitis in pregnant women is a common inflammatory periodontal disease that appears from the third month of pregnancy with an overall prevalence of 35 to 100%. This condition is induced by oral biofilm and exacerbated by increased levels of sex steroid hormones characteristic of pregnancy. Strict bacterial plaque control with both professional and home oral hygiene is essential. Manual toothbrushes require a more specific manual technique for women, while sonic electric toothbrushes, due to their ease of use, might be an excellent for oral individual prophylaxis. Therefore, the question of which type of manual or electric toothbrush might be more effective in reducing gingival inflammation in pregnant women is still unresolved. In literature there are a large number of in vitro clinical studies on this topic, there are currently no clinical studies investigating this long-term clinical comparison. In this context, this study is a randomized clinical trial consisting of a comparative evaluation between two manual and two sonic electric toothbrushes in the efficacy of the control of plaque in order to reduce gingivitis in women during the period of pregnancy.

Levothyroxine Intervention in Pregnant Women with TSH （2.5 MIU/L-upper Limit of Reference Range） and Negative Thyroid Peroxidase Antibody

The goal of this clinical trial is to learn if levothyroxine (L-T4) works to treat pregnant women with TSH 2.5 mIU/L-the upper limit of reference range (ULRR) of pregnancy and TPOAb-negative. It will also learn about the safety of L-T4. The main quesitons the investigator want to answer are: * Will L-T4 reduce miscarriage rates and have an impact on pregnancy complications in pregnant participants? * What medical issues do participants have when taking L-T4 during pregnancy? -Investigators will compare L-T4 with placebo (a substance with a similar appearance without medication) to see if L-T4 could reduce miscarriage rates Participants should: * Take L-T4 or placebo during the whole pregnancy. * Visit the hospital once every 6-8 weeks during pregnancy for checkups and tests * Keep a diary of their pregncny complications and daily record of L-T4 or placebo intake. * Visit the hospital for examination 42 days postpartum for checkups and follow up by phone at 6 and 12 months postpartum.

Physical Activity and Sedentary Behavior During Pregnancy

Our main objective is to evaluate the intervention that best enables women's adherence to physical activity (PA). Our hypothesis is that identifying types of interventions suitable for pregnant women (in-person PA sessions, videoconferences or mixed format) could help improve their PA level and simultaneously reduce their sedentary behavior (SB).

Modifying Nutrition to Modify Delivery in Nulliparous Women

In France, around 20% of women exceed the term of 41 weeks' amenorrhoea (SA). Maternal and foetal morbidity and mortality are increased when the term is exceeded, which justifies inducing labour. However, induction also increases maternal and foetal morbidity. According to several studies, regular consumption of dates during the last month of pregnancy may increase the rate of spontaneous labour and natural childbirth. Single-centre, randomised, open-label, 3-arm study : Experimental group n°1: 'dietary advice + food provided'. Advice to eat 7 dates a day from 37 weeks' gestation until delivery. The quantity of dates required will be provided to the women. Experimental group 2: 'dietary advice alone'. Advice to eat 7 dates a day from 37 weeks' gestation until delivery. The food will not be provided. Control group: no specific dietary advice. Routine care group.
