Filter by:Abnormal uterine bleeding "AUB" describes all abnormal forms of menstrual bleeding which may result from several causes including anovulation, problems related to pregnancy, infections, vaginal and cervical abnormalities, uterine pathologies including benign and malignant tumors, coagulopathies, endocrine disorders, trauma, foreign bodies, systemic diseases and iatrogenic causes. AUB may be clinically presented by menorrhagia, metrorrhagia or menometrorrhagia. It's the most common complaint for the reproductive age females and accounts for 33% of female patients referred to gynecologists
The goal of this clinical trial is to test intracerebral transplantation of stem cell product in patient with chronic intracerebral hemorrhage. The main questions aims to answer are: - The safety of the product - The efficacy of the product
Low levels of serum triiodothyronine (T3) thyroid hormones (T4) are a strong predictor of mortality and poor prognosis in critical care patients. Few reports, however, have focused on neurocritical patients. Patients with severe neurological diseases often experience more complications and exhibit higher mortality rates, and many studies have provided evidence for a low T3/T4 state being an important prognostic indicator in such cases; Lieberman et al. found that 87% of individuals with severe traumatic brain injury have thyroid function below the mid-normal range. Other researchers showed that low T3 syndrome is a predictor of poor prognosis in cerebral infarction patients; their findings indicated the central hypothyroidism and disturbance of thyroid hormone metabolism were involved. Low T3 syndrome is common in patients with brain tumors and has been shown to be associated with shorter survival in glioma patients. Despite these observations, however, whether the thyroid hormone abnormalities in the critically ill are a physiological adaptation or a pathological change, and whether hormone replacement therapy (HRT) can benefit such patients, remain to be established. As acute progression ceases, thyroid hormone levels may return to normal. This may imply that thyroid hormone supplements could improve the prognosis of patients with secondary hypothyroidism. Previous clinical studies have examined the effect of thyroid HRT on patients undergoing cardiac surgery; patients with malnutrition, heart failure, or acute renal failure; and premature infants with acute respiratory distress syndrome. Most of these past studies found no significant positive effects on prognosis, and no harmful effects either. Some smaller studies have demonstrated potential promise for the use of HRT; for example, one study showed that T3 supplementation in patients undergoing cardiac surgery could lead to less need for inotropic support and better hemodynamic parameters. There are no reports of thyroid HRT improving the prognosis of neurocritical patients with secondary hypothyroidism. The application of hormone replacement therapy in the treatment of neurocritical patients with secondary hypothyroidism remains controversial. This study aims to explore the safety and effectiveness of thyroid hormone replacement therapy in patients with spontaneous intracerebral hemorrhage and concomitant secondary hypothyroidism.

Aim of the Work is To determine the significance of the placental thickness and the thickness of the uterine muscle layer at placenta attachment in the prediction of postpartum hemorrhage and to evaluate both of them as as parameters for identifying high-risk patients.
In the RoTIS study, the investigators would like to test the robotic stabilizer for the subretinal injection of tPA in patients with subretinal hemorrhage during standard-of-care surgery. The surgical devices used during this procedure will be the following: - The robotic stabilizer (prototype - FAMHP approval received) - 41G subretinal needle (CE marked - used within label) - Inicio micro-injection system (CE marked - used within label) The Inicio system mounted with the 41G needle will be held by the robot, and guided by the surgeon towards the required position. When the tip of the needle is in the desired subretinal position, the robotic stabilizer will be locked and the tPA will be injected till sufficient subretinal bleb formation is obtained, with a maximal duration of up to 3 minutes. As performed routinely, the surgical view through the microscope will be video-recorded and while the injection is being administered, the built-in iOCT of the Artevo surgical microscope (Zeiss, Oberkochen, Germany) will be used to scan the retina area around the injection site to record the subretinal bleb formation for later review.
The investigator's propose a multicenter prospective observational study to investigate the use of embolization in patients with negative angiogram and to ascertain the optimal level of treatment when the angiogram is positive; non-selective vs. selective embolization.
Introduction Portal hypertension is a common complication of liver cirrhosis and is often underestimated in clinical diagnosis. The incidence of portal hypertension is approximately 20% to 98% in patients with cirrhosis (Wu et al., 2022). It is the major driver in the transition from the compensated to the 'decompensated' stage of cirrhosis, defined by the presence of clinical complications, including ascites, spontaneous bacterial peritonitis, hepatorenal syndrome, and hepatic encephalopathy (Berzigotti., 2017). Acute variceal bleeding is one of the most lifethreatening complications of liver cirrhosis. Twenty two percent to sixty one percent of cirrhotic patients receiving primary prophylaxis will develop first variceal bleeding during the first two years of follow up. Furthermore, variceal bleeding is associated with high risk of rebleeding and mortality (Tantai et al., 2019). Patients with cirrhosis, although much progress has been made in diagnosis and treatment using vasoactive drugs, preventive antibiotics, early endoscopy and interventional radiology, the 6-week mortality rate remains high, ranging from 10 to 20%, mainly due to failure to control bleeding in the first days. Therefore, the prognostic method of patients with acute variceal bleeding is to determine the risk of rebleeding and resistance to standard treatment (accounting for 20-30%) and mortality rate in order to be able to adopt more aggressive treatment measures. The prognosis is very important but also difficult, not only because of the bleeding status but also depending on the severity of the underlying cirrhosis (Huy et al., 2023). Many risk factors are known to influence the outcome in Upper Gastrointestinal Bleeding (UGIB) setting: Age, comorbidities, presence of shock, endoscopic diagnosis, haemoglobin values at the time of bleeding, stigmata of recent haemorhage and need for blood transfusion have all been described as significant risk factors for rebleeding and death (Monteiro S et al., 2016). Many risk assessment score systems, including pre-endoscopy and post-endoscopy evaluations, have been developed to predict outcomes such as the need for hospital-based intervention, endoscopic therapy, and admission to an intensive care unit (ICU), rebleeding, and mortality. Some studies showed that these scoring systems distinguish low-risk patients who can potentially be managed as outpatients, allowing more efficient use of resources. Other studies suggested that these score systems distinguish higher-risk patients who might require emergency endoscopy or management in an intensive care unit (Li et al., 2022). In 1993, the Rockall Scoring system was introduced to predict the mortality after UGIB and was validated for its use to identify the patients at high risk for re-bleed and mortality. Complete Rockall scoring system is based on an initial clinical score at the time of admission which consist of age (score 0-2), presence of shock (0-2), co-morbidities (score 0-3) and post endoscopic diagnosis (score 0-2) with stigmata of recent hemorrhages (score 0-2). Both clinical and post endoscopic scores added together gives a complete Rockall score with maximum score being 11 (Dewan et al., 2018). In 2020, Laursen S.B. and colleagues conducted a multicenter international study and developed a new prognostic scoring system for UGIB called the ABC score. This scoring system is based on three criteria: age, blood test results, and comorbidities. The score ranges from 0 to 18 points, categorizing the risk into low (≤3 points), moderate (4-7 points), and high (≥8 points) levels. The 30-day mortality rates for high-risk UGIB patients in these three risk groups were 1%, 7%, and 25%, respectively ( Ky et al., 2023) The new Cologne Watch (C-Watch) score was designed as a pre-endoscopic score for acute variceal and non-variceal UGIB and incorporates laboratory values only (c-reactive protein, white blood cell count, alanine-aminotransferase, thrombocytes, creatinine, and hemoglobin) with a minimum point value of 0 and a maximum point value of 8. Within the validation set, it predicted a composite endpoint consisting of recurrent bleeding, need for intervention (interventional radiology, surgery), or death within 30 days with an area under the receiver-operating characteristics curve (AUROC) of 0. About 38.7% of patients were within the high-risk group, i.e., ≥2 points, reached the composite endpoint, whereas no patient classified as low risk (≤1 point) (Allo et al., 2022).
Uterine leiomyomas, or fibroids, are common benign tumors among women, especially those over 35 years old. They can cause various issues, including heavy menstrual bleeding, anemia, pelvic pain, and pressure symptoms. Surgery is often necessary for symptomatic fibroids, with hysterectomy recommended for women over 40 and myomectomy for those wishing to preserve their uterus. Myomectomy can be performed using different surgical approaches but can be associated with significant morbidity, particularly major blood loss, especially in abdominal myomectomy, where up to 20% of women may require blood transfusion. Various interventions have been introduced to reduce bleeding during myomectomy, such as tourniquets, bupivacaine plus epinephrine infiltration, vasopressin injection, preoperative GnRH agonist administration, and preoperative ascorbic acid injection. However, these strategies may have complications, be ineffective, expensive, or require extra steps. Oxytocin, primarily secreted from the pituitary gland, is crucial for uterine contraction during labor and delivery, and is used to prevent postpartum uterine atony and bleeding. However, caution is needed in its use, especially in women with heart disease or hypovolemia. Misoprostol, a prostaglandin E1 analogue, can reduce bleeding during myomectomy by promoting myometrial contractions and reducing uterine artery blood flow. It can be administered via multiple routes, with rectal administration showing advantages in maintaining high plasma concentrations during surgery. Studies have investigated the effectiveness of single preoperative rectal doses of misoprostol versus preoperative oxytocin in reducing bleeding during abdominal myomectomy.
