NCT ID: NCT05461963 Completed - Breast Feeding Clinical Trials

The Relationship Between Breastfeeding During Early Pregnancy and Miscarriage

Start date: June 26, 2022
Phase:
Study type: Observational

Breastfeeding provides various health and psychological benefits to mothers and their babies. It also acts as an effective method of natural contraception when applied strictly for up to six months after birth. Studies show that breastfeeding times are getting longer in the USA and more babies are breastfed for more than 12 months compared to the past. Recent research shows that 57% of US infants are breastfed until at least six months of age, and more than a third continue to be breastfed for up to 12 months. Prolonged breastfeeding durations increase the prevalence of breastfeeding during pregnancy, especially with the shortening of the intervals between pregnancies. Breastfeeding during pregnancy is a relatively common practice in many parts of the world. According to the data of studies conducted in low- and middle-income countries, it has been determined that 35% of the last born babies continue to be breastfed in the next pregnancy of their mothers. It has also been shown that the prevalence of breastfeeding during pregnancy in low-income countries is between 15% and 50%. Few research has been done on the relationship between breastfeeding during pregnancy and maternal, infant, or pregnancy outcomes. Some studies have suggested that hormonal mechanisms in pregnancy may link breastfeeding during pregnancy and abortion. When babies stimulate the nipple and areola during sucking, they trigger the release of oxytocin in the mother, causing a series of reactions that push the milk towards the nipple. We know that the prevalence of short and long breastfeeding intervals in pregnancy is high in our country. Therefore, in this study, we are planning to investigate whether there is a relationship between breastfeeding during pregnancy and miscarriage based on this information.

Treatment of Missed Miscarriage With TRUCLEAR Tissue Removal System, a Feasiblity Study

Start date: March 5, 2020
Phase: N/A
Study type: Interventional

the Aim of this study is to prospectively study the feasibility of evacuation of products of conception (POC) in missed miscarriages up to 10 weeks using the TRUCLEAR tissue removal system in order to achieve targeted treatment under direct vision of the POC and thus potentially reducing the risk of complications and intrauterine adhesions

NCT ID: NCT04492098 Completed - Miscarriage Clinical Trials

Mucosal-Associated Invariant T Cells in Cases of Miscarriage

Start date: June 1, 2021
Phase:
Study type: Observational

Miscarriage is the most frequently encountered complication of pregnancy ranging from 10% to 30%. The etiology of recurrent spontaneous miscarriage (RSM) in 40%-50% of cases cannot be identified. Immunological disturbances have been suggested to play an important role. Previous studies have focused that women with miscarriage have elevated NK cell numbers and activity both in the periphery and in the endometrium. Also, NK cells in women with RSM displayed an imbalance of Killer cell Ig-like receptors (KIRs) in favor of activating KIR leading to an unbalanced activation of dNK cytotoxicity and higher risk of miscarriage.

NCT ID: NCT04190043 Completed - Miscarriage Clinical Trials

Womens's Experiences of Pregnancy Loss Aftercare in the Gynecological Emergency

Start date: January 1, 2020
Phase:
Study type: Observational

Introduction: Scientific papers on the womens's experiences of pregnancy loss aftercare in the emergency department show that how announcement is made and how much caregivers show empathy to women, help women to face this difficult moment. However, in most studies, women say they did not have enough information nor support from the medical teams. Diagnosis of miscarriage in the emergency department is the routine for the caregiver but is often experienced by the woman as the loss of a child. This study has for goal to bring to light the discrepancy between the caregivers's experience and the women's experience :the given information, the time for consultation, the empathy. Methods : 2 months after the diagnosis of miscarriage in the emergency room, patients receive a phone call with explanations about the project. If the patient gives her consent, she receives a computer questionnaire by email (questions about : reasons for coming to the emergency room, circumstances of announcement, information given in the emergency room, satisfaction with the careā€¦) In parallel, caregivers have to complete a questionnaire about the same parameters. The main objective of this study is to evaluate womens's experiences of pregnancy loss aftercare in the emergency department of Montpellier Hospital. The second objective is to assess the discrepancy between the patient's experience and the caregivers' experience in this situation with the aim of suggesting improvement.

NCT ID: NCT03940495 Completed - Miscarriage Clinical Trials

Serum Kisspeptin: a Predictive Marker of Miscarriage or Not?

Start date: May 1, 2019
Phase:
Study type: Observational

This is a prospective observational study. Eligible women undergo ART treatment in our centre will be recruited for the study and each woman will only be included in the study once. Informed written consent will be obtained. Blood serum for hCG level is performed 14 days after the embryo transfer i.e. week 4. If the serum hCG level is >10IU/L, the women are considered pregnant and blood will be saved and checked for kisspeptin level, Another blood test is repeated 1 week later i.e. week 5. A transvaginal ultrasound and blood test will be performed 1 week later i.e. week 6 to confirm the fetal viability and the number of gestational sacs and locate the pregnancy. Blood for hCG and kisspeptin levels are checked at weeks, 4, 5 and 6. Ultrasound will be performed at gestational 8 weeks and 11 weeks. They will be referred for antenatal care when the pregnancy is confirmed on-going at 11 weeks. The purpose is to determine whether serum kisspeptin level in women who conceive in IVF is associated with an increased risk in first trimester miscarriage and compare with serum hCG level in the prediction of the first trimester miscarriage.

NCT ID: NCT03442335 Completed - Miscarriage Clinical Trials

Implantation Test for Endometrial Receptivity

Start date: December 12, 2017
Phase:
Study type: Observational

Background Miscarriage is the most frequent complication of pregnancy and represents the spontaneous loss of the embryo or foetus before it is able to survive independently (24 weeks of gestation). It affects up to 50% of pregnancies with the vast majority (80%) occurring at pre-clinical stage before the woman recognises the pregnancy. Up to 5% of couples suffer recurrent miscarriage defined as 2-3 or more miscarriages leading to physical, emotional and financial consequences for couples, doctors and medical systems. Different maternal health problems (thyroid disease, sticky blood, autoimmune disease, anatomical anomalies of the womb) and embryo defects may be responsible for some of the miscarriages; however, more than 50% of the occurrences have no identifiable cause based on the current diagnostic tests. Aim The aim of the present research proposal is to understand the role of the lining of the womb in miscarriage and to explore the development of a potential implantation test that is cost-effective and may be implemented in clinical practice. Methods Over a period of two years, women who suffered recurrent miscarriage will be approached in the advanced miscarriage clinic at Birmingham Women's Hospital during their routine appointment. Participants will be invited to participate by undergoing chromohysteroscopy and/or a biopsy from the lining of the womb during an outpatient appointment. Chromohysteroscopy is based on a routine hysteroscopy which involves visualising the inside of the womb using a narrow telescope passed through the neck of the womb (cervix). "Chromo" comes from the fact that an iodine based dye will be injected to increase the power of the test. The biopsy will be taken using a narrow plastic tube passed through the cervix. It is a standard diagnostic test for women with abnormal bleeding. As part of the present research, different cells and molecules will be analysed from the biopsy sample.
