Filter by:Evaluate surgical treatment outcomes and identify best practice guidelines for complex adult spinal deformity (ASD) patients treated with minimally invasive approach, including radiographic and clinical outcomes, surgical and postoperative complications, risk factors for and revision surgery rates, and the role of standard work to improve patient outcomes and reduce surgical and postoperative complications.
In current practice, options for venous and lymphatic malformations remain limited. Recently an oral medication, sirolimus, has been found to benefit patients when taken once or twice a day for several months. Unfortunately there are many side effects associated with this medication, some of which can be severe including, neutropenia, oral ulcerations, and lab abnormalities. The purpose of this study is to determine if once weekly dosed sirolimus will be effective for the treatment of venous and lymphatic malformations. Additionally, the study will evaluate patient satisfaction and identify adverse effects. Participants will be on the medication for 6 months with an option to continue after this time period.
This prospective multicenter study will evaluate the efficacy of a real-time artificial intelligence system for detecting multiple ocular fundus lesions by ultra-widefield fundus imaging in real-world settings.
The MiMBa (Malaria in Mothers and Babies) Pregnancy Registry aims to generate robust evidence on the safety of a range of antimalarials when used in pregnancy, particularly in the first trimester. This will be a multi-country observational study and will be deployed in several field sites in Africa.
Malignant pleural mesothelioma (MPM) is a rare pleural cancer, which could be primary or secondary to an asbestos exposure. To enhance our knowledge of this rare disease, an exploration of genetic and tumor mechanism is mandatory. One of the principal difficulty is to harvest sufficient tumour pieces to perform multi-omics analysis. The goal of the SCITH-MESO study is to harvest larges pieces of tumour during a routine surgical procedure of MPM diagnosis by mean of pleural biopsies during VATS surgery. Operating samples will increase a tissue bank collection (CRB).
The project aims to find a relationship between the positioning of the foetus before and during birth and the results of obstetrics and to determine their incidence in the Polish population. The study will be conducted by combining the use of ultrasound diagnostics, midwives observations during childbirth, analysis of medical documentation and a questionnaire on the activity of examined women. The obtained results will be used to prepare guidelines for the birth in a particular foetus position.
The aim of the study is to assess the impact of SMR intervention in the hamstring muscles on the activity of the biceps and gluteus muscles.
Prospective research in which patients who applied to UUTF Gynecology and Obstetrics ART center for the treatment of infertility (inability to conceive despite one year of unprotected sexual intercourse), who will undergo IVF due to PCOS and unexplained infertility
Cerebral and medullary arteriovenous malformations (AVMs) are morphologically abnormal vessels located on the surface or in the cerebral or medullary parenchyma. These vascular lesions cause the arterial and venous networks to communicate pathologically, creating an arteriovenous shunt.The prevalence of cerebral Cerebral and medullary AVMs in general population is difficult to establish given the rarity of the condition. However, it is estimated at around 1 per 10,000 inhabitants (0.01%). About 15-20% of the cerebral vascular accidents are asymptomatic at the time of diagnosis. The occurrence of intracranial haemorrhage is the most important prognostic factor because it is associated with a significant morbidity and mortality. The management of an AVM is usually carried out in a multidisciplinary way, combining interventional neuroradiology, neurosurgery and vascular neurology. The genetic, molecular and cellular mechanisms that cause vascular malformations of the central nervous system are partially known. Several recent research works highlight mutations in the RAS-MAPK or MAPK-ERK signalling pathway in AVMs. In cases of cerebral AVMs considered to be sporadic, a somatic KRAS/BRAF mutation has recently been demonstrated in tissue samples of operated AVMs. Except in the case of Hereditary Haemorrhagic Telangiectasia (HHT or Rendu-Osler-Weber syndrome), the influence of genetic damage on the prognosis of AVM is poorly known. It is also interesting to note that genetic screening is not routinely performed in patients with cerebro-medullary AVMs and that therefore the prevalence of these clinical entities in patients with AVMs is not known.
Out objective is to identify the mechanisms that promote hepatic and myocardial fibrosis, and collateral vessel formation in patients with complex congenital heart disease and Fontan circulation.
