Comprehensive Assessment of First Trimester Pregnancy Loss
The FIRST-CARE Study is a prospective research project conducted at Hospital de la Santa Creu i Sant Pau (Barcelona, Spain), aimed at better understanding the causes and consequences of first-trimester pregnancy loss (miscarriage). Miscarriage is a common event that affects about 15% of clinically recognized pregnancies and can have both physical and emotional consequences for women and their partners. However, many questions about its causes remain unanswered, and most women do not receive a clear explanation or personalized support after experiencing a loss. This study will include 225 women who have experienced a miscarriage during the first 14 weeks of pregnancy. Two groups will be studied: those who have had a miscarriage for the first time and those with a history of recurrent pregnancy loss (defined as two or more previous miscarriages). The aim is to investigate a wide range of possible causes - including genetic, hormonal, immune, cardiovascular, placental, and psychological factors - in order to improve diagnosis and develop more personalized care strategies. Participants will undergo a comprehensive evaluation including ultrasound, blood tests, genetic testing, and psychological assessments. In some cases, their partners will also be invited to participate. Women will be followed for one year to assess their mental well-being and reproductive outcomes, such as the chance of getting pregnant again and the outcome of future pregnancies. The study will also create a biobank of biological samples to support future research in the field of pregnancy loss. By combining clinical evaluations, laboratory tests, and personal experiences, this study aims to uncover new insights into why miscarriages happen and how to better support women and couples going through this experience. The ultimate goal is to provide better diagnostic tools, care pathways, and support systems to reduce the emotional burden of miscarriage and improve reproductive health outcomes.

Letrozole Plus Misoprostol Versus Misoprostol Alone for Treating Women With Missed Miscarriage
The goal of this clinical trial is to learn whether adding the medicine letrozole to Misoprostol helps women have a complete abortion more often than using Misoprostol alone for the treatment of missed miscarriage (when a pregnancy has stopped developing but has not yet passed naturally). The main questions this study aims to answer are: 1. Does taking letrozole for 3 days before misoprostol increase the chance of a complete abortion compared to misoprostol alone? 2. Does the use of letrozole affect the time it takes for abortion to occur? Who can Join? i. Women up to 13 weeks of pregnancy (based on last menstrual period and confirmed by ultrasound) who have a missed miscarriage. ii. Only those with a single pregnancy are eligible. iii. Women with a previous cesarean section or uterine scar are not included. What Will Happen in the Study A total of 92 women will take part. Participants will be randomly assigned to one of two groups: Group A: Letrozole tablets once daily for 3 days, followed by one dose of vaginal misoprostol. Group B: Placebo tablets for maximum of 3 days, followed by one dose of vaginal misoprostol. Doctors will monitor whether the abortion is complete within 24 hours. If it is not, other medical procedures will be offered as needed. Products of conception will be examined to confirm abortion.

Letrozole and Misoprostol for Early Pregnancy Loss Management
A pilot cohort study to preliminarily investigate the efficacy of pretreatment with letrozole 10 mg daily for three consecutive days followed by treatment with misoprostol 800 mcg vaginally for medical management of early pregnancy loss in a US population. Patients will be followed to assess efficacy of this treatment regimen, as well as additional interventions needed, side effects, adverse events, and patient acceptability.

Hysteroscopic Resection Versus Manual Vacuum Aspiration for Early Pregnancy
Early pregnancy loss happens when a pregnancy that is not developing properly is found on an ultrasound before 12 weeks and 6 days. This type of loss occurs in about 10% of pregnancies. There are three main ways to treat this: waiting for it to pass naturally, using medication, or having surgery. Surgery is the most effective, working 99% of the time, compared to waiting (80% effective in 8 weeks) and medication (71-84% effective). Currently, surgery involves dilation of the cervix and curettage (removal of pregnancy tissue) with suction provided either from a manual hand-held pump or a machine. For the purposes of this study, a manual vacuum aspirator (or hand-held pump) will be used with ultrasound guidance. There is also another method called hysteroscopic resection, where the doctor uses a special camera to directly see and remove any pregnancy tissue from your uterus. Patients often want the quickest way to resolve the pregnancy loss, and physicians are unsure which surgical method is the best. It's also unclear if one type of surgery causes less scar tissue inside the uterus, affects the ability to test the tissue for genetic issues, or impacts how soon a patient can start fertility treatments again. This study aims to find out if hysteroscopic resection provides faster resolution and creates less scar tissue compared to the manual vacuum aspiration.

Non-invasive Monitoring of Miscarriage
cfDNA is extremely useful to ascertain chromosomal causes of miscarriages at the point of miscarriage diagnosis by a simple blood test. This study aims to determine the level of cell-free DNA (cfDNA) in early pregnancy and compare the results with those of product of conception (POC) testing, in concordance with standard karyotyping.

Machine Learning Miscarriage Management Clinical Decision Support Tool Study
Machine learning used to develop an algorithm to determine chance of success with expectant or medical management for an individual patient. Taking into account the following objective measures: * Demographics: Maternal Age, Parity * History: Previous CS, Previous SMM/MVA, Previous Myomectomy * Gestation by LMP * Presenting symptoms: Bleeding score, Pain score * USS Measurements: CRL, GS, RPOC 3 dimensions, Vascularity * Discrepancy between gestation by CRL and LMP Audit to collate 1000 cases and identify features contributing to an algorithm that can predict outcome of miscarriage management for individualized case management.
