Active clinical trials for "Recurrence"

The risk for recurrence after ventral hernia repair is often based on reoperation rates with short follow-up rather than recurrences identified by clinical examinations. The purpose of current study is find the real incidence of recurrences 3 years after ventral hernia repair and to compare with the reoperation rate.

Review bladder cancer patients and form a database in regards to urine cytology.

To evaluate the impact of capsular incisions on biochemical recurrence (BCR) and the potential risk factors of capsular incisions.

This proposal is part of the INIA Stress Consortium. This study will explore the contributions of lifetime trauma, recent stress, and alcohol use on stress-hormone axis disruption in treatment seeking, one-month abstinent, alcohol-dependent subjects assess the combined contributions of stress-hormone axis disruption and episodic stress on the risk of prospective drinking following treatment determine the role of neurosteroids in alcohol use.

In recurrent miscarriage, the male factor has been poorly evaluated. In fact, in the vast majority of clinical protocols of recurrent miscarriage, the sperm is not considered or assessed. Recently, some studies have suggested the presence of genetic and metabolic sperm anomalies in couples suffering from repeated miscarriages. Specifically, DNA fragmentation and altered oxidative stress in the sperm and Y microdeletions from blood samples have been related to an increased risk of miscarriage.The aim of the present study is to compare these three parameters in: couples with recurrent miscarriage; oligozoospermic men with or without recurrent miscarriages; and healthy sperm donors, in order to determine their actual impact on this reproductive problem.

Venous thromboembolism (VTE) is a common and potentially fatal pathology in France. The risk of recurrence is around 5 to 7% per year. The identification of patients at risk of VTE and its prevention is a real health issue in particular. 50% of MTEV recurrences occur in the absence of a risk situation, suggesting the involvement of specific risk factors for MTEV recurrence that have not been identified to date. In the last ten years, so-called "genome-whole" or "genome wide" association (GWAS) approaches have identified new genetic risk factors for the first episode of VTE. On the other hand, no study has focused on the predictive factors of recurrence. The previous project, conducted from 2012 (NCT02904967), had as its main objective to identify new genes for susceptibility to MTEV recurrence by comparing cases of MTEV recurrence versus controls having had a single episode of MTEV. The MARTHA cohort (1,542 patients) is extremely valuable study material and is one of the few cohorts in the world with genome-wide data in the field of VTE. Follow-up could only be performed in 359 patients, 76 (21%) of whom presented with a new episode of VTE. The objective of this project is to increase the number of patients for whom the investigators will have information on recurrence / non-recurrence of VTE, by querying national registries on the vital status of patients, and possible causes of death. . These new data on the occurrence or not of a new thrombotic episode, will be confronted with the genetic data already available in all the patients in order to identify specific genetic risk factors and potentially predictive of the recurrence of MTEV.

This study aimed to investigate the outcome of patients who had their asparaginase treatment truncated in the NOPHO ALL2008 protocol.

This trial studies the frequency of incident and prevalent of cancer in people living with human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) at cancer centers in Latin America. By counting how many people living with HIV/AIDS have cancer at these specific centers, researchers may better understand how they are being treated and cared for. This may help researchers to understand what new studies may be helpful for those areas in the future.

This study evaluates whether tumors present in patients with cancer who are planned to get CAR T-cells have low amounts of oxygen (hypoxia). PET scans may be used to check the amounts of oxygen within areas of cancer with a special radioactive tracer called FAZA that specifically looks for areas of low oxygen. This study is being done to help researchers determine how the amount of oxygen within areas of cancer affect how well CAR T-cells kill cancer cells.

To evaluate histopathological findings of products of conception in both sporadic and recurrent miscarriage. To determine the prevalence of chronic histiocytic intervillositis in both sporadic and recurrent miscarriage.
