Filter by:This is a cross-sectional study to evaluate the variation of biological biomarkers of oxidative stress and inflammation in response to the external exposome, in people with Multiple Sclerosis (pwMS).The objective is to study the variation of biological biomarkers of oxidative stress and inflammation in response to external exposome in pwMS, controlling for other biomarkers (cytokine, neurofilaments, microbiome), gender, age, anthropometric measurements, vitamin D levels and medical history. Specifically, the variation of microRNAs is defined as the primary outcome, in response to urban air pollution, urbanization, lifestyle and quality of life components of the external exposome. Following the functional exposome approach:(1)Information on a pwMS sample about socio-demographic characteristics and medical history will be collected and specific components of the (2) On the same pwMS sample, the internal exposome variation will be measured. MicroRNA levels and gut and nasal microbiota alpha- and beta-diversity and relative bacterial abundances will be considered as biomarkers of oxidative stress and inflammation. At the same time, cytokines and neurofilament proteins (NfL) will be measured as biomarkers of neurodegeneration and axonal damage. Adults (≥ 18 years) pwMS, with relapsing-remitting course, diagnosis of MS according to 2017 McDonald criteria and residing in Pavia or Milan (Italy) will be included. Potentially eligible pwMS will be screened by a neurologist expert in MS who will verify that all the inclusion criteria will be fulfilled. To validate variation among 7 selected MS diagnostic miRNA, in response to urban air pollution, urbanization, lifestyle and quality of life components of the external exposome, the differential expression (ΔCT) for each miRNA will be considered as the outcome measure. Two hundred eligible pwMS who meet the inclusion criteria and sign the informed consent will be included in the study, to consider 15% dropout at the blood sampling stage.
The goal of this clinical trial is to compare a placebo (a look-alike substance that contains no active drug) with a commonly used antibiotic in children with Mycoplasma pneumoniae (a specific bacterium) induced community-acquired pneumonia. The main question it aims to answer is: Is antibiotic treatment needed in Mycoplasma pneumoniae (a specific bacterium) induced pneumonia? Participants will receive either a placebo or a antibiotic treatment and track their symptoms and vital signs until they are healthy. Researchers will then compare the length of symptoms between the placebo and the antibiotic group.
This clinical trial evaluates changes in quality of life after two treatments with near margin-less adaptive radiation therapy (ART) compared to five treatments with standard stereotactic ablative body radiotherapy (SABR) in patients with prostate cancer that has not spread to other parts of the body (localized). ART is a type of radiation therapy that uses information gathered during the treatment cycle to inform, guide, and alter future radiation treatments with respect to location and dose. It may be able to deliver radiation to the site of disease over a shorter time and with smaller margins (less treatment delivered to nearby healthy tissues). SABR is a type of external radiation therapy that uses special equipment to position a patient and precisely deliver radiation to tumors in the body (except the brain). The total dose of radiation is divided into smaller doses given over several days. This type of radiation therapy helps spare normal tissue. Shorter duration near margin-less ART may be just as effective at treating patients with localized prostate cancer but have less quality of life side effects than standard SABR.
The study will investigate and compare the three techniques in drainage of subretinal fluid in patients with macula off RRD: namely using the original break, performing a posterior drainage retinotomy and using PFC with drainage through the original break or peripheral retinotomy regarding the presence of persistent sub-retnal fluid and related intra or postoperative complications
This phase I trial tests the safety, side effects, and best dose of a personalized vaccine (tumor membrane vesicle or TMV vaccine) by itself and in combination with checkpoint inhibitor (pembrolizumab or ipilimumab) in treating patients with triple negative breast cancer. This vaccine is made by taking a piece of patient's triple negative breast cancer to design a vaccine to stimulate the immune system's memory. Patients are treated with the personalized vaccine immunotherapy with or without monoclonal antibodies, such as pembrolizumab and ipilimumab. This approach may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving personalized TMV vaccine with pembrolizumab or ipilimumab may help the immune system attack cancer better and reduce the risk of this breast cancer coming back or growing.
The CIEDOUT study is an open label randomized trial in patients with possible cardiac implantable electronic device (CIED) infection. The hypothesis is that CIED removal + guideline antibiotic therapy is better than 6-weeks antibiotic therapy alone in preventing death or relapse of bacteremia in patients with bacteremia and possible CIED infection (not definite CIED infection). The objective of this study is to test whether CIED removal + guideline antibiotic therapy is superior to 6-weeks antibiotic therapy alone in prevention of the composite endpoint of death or relapse bacteremia after 6 months of follow-up in patients with CIED and systemic infection but without definite CIED infection.
Older people falling from a standing height is the most common cause of hospital admission for head injury. Up to 1 in 3 patients admitted are taking a tablet medication which thins the blood, known as an oral anticoagulant. This type of medication can increase the likelihood of bleeding in the brain. Many patients are taking oral anticoagulation due to having an irregular heartbeat (called atrial fibrillation) or because of having a previous stroke or blood clots. When a scan shows blood in the brain, oral anticoagulation is nearly always stopped. However, this leaves the question of when it is safe to restart them. The risk of making the bleeding in the brain worse must be balanced against the risk of having a stroke or blood clots. There is no clear evidence on the safest time to restart oral anticoagulation, but most neurosurgeons advise restarting them 1-4 weeks after head injury. The number of people who have a bleed on their brain after a head injury is increasing and further brain bleeding or a stroke can have a serious effect on patients' lives and their on-going healthcare needs. Public and patient groups have highlighted that many patients want to stop taking oral anticoagulation after a bleed but they may be unaware of the vital importance of restarting this medication to prevent strokes and blood clots. The most popular oral anticoagulation prescribed has changed in recent years from warfarin to newer medications called Direct Oral Anti-Coagulants (DOACs). This trial will recruit 1084 people who are admitted to hospital with a bleed on the brain caused by a head injury who were taking oral anticoagulation before their head injury and have been prescribed a Direct Oral Anti-Coagulant (DOAC) for previously diagnosed medical condition. Patients on other Oral Anti-Coagulants, such as Warfarin may also be able to take part. The main purpose of the trial is to determine when is most beneficial time for people to start or restart a DOAC after their head injury. People will be asked to start the medication either 1 week or 4 weeks after their head injury. They will be then followed closely for 12 weeks and any major bleeding events or a blood clots (thrombotic events) such as a stroke or heart attack will be recorded. The study will also look at the person's overall quality of life, how they recover physically, the number of people who die, the costs of the treatment, and the attitudes of people and their caregivers to starting or restarting a DOAC.
Acute respiratory distress syndrome (ARDS) is associated with high mortality, some of which can be attributed to ventilator-induced lung injury (VILI) when artificial ventilation is not customized to the severity of lung injury. As ARDS is characterized by a decrease in aerated lung volume, reducing tidal volume (VT) from 12 to 6 mL/kg of predicted body weight (PBW) was shown to improve survival more than 20 years ago. Since then, the VT has been normalized to the PBW, meaning to the theoretical lung size (before the disease), rather than tailored to the severity of lung injury, i.e., to the size of aerated lung volume. During ARDS, the aerated lung volume is correlated to the respiratory system compliance (Crs). The driving pressure (ΔP), defined as the difference between the plateau pressure and the positive end expiratory pressure, represents the ratio between the VT and the Crs. Therefore, the ΔP normalizes the VT to a surrogate of the aerated lung available for ventilation of the diseased lung, rather than to the theoretical lung size of the healthy lung, and thus represents more accurately the actual strain applied to the lungs. In a post hoc analysis of 9 randomized controlled trials, Amato et al. found that higher ΔP was a better predictor of mortality than higher VT, with an increased risk of death when the ΔP > 14 cm H2O. These findings have been confirmed in subsequent meta-analysis and large-scale observational data. In a prospective study including 50 patients, the investigators showed that a ΔPguided ventilation strategy targeting a ΔP between 12 and 14 cm H2O significantly reduced the mechanical power, a surrogate for the risk of VILI, compared to a conventional PBW-guided ventilation. In the present study, the investigators hypothesize that the physiological individualization of ventilation (ΔP-guided VT) may improve the outcome of patients with ARDS compared to traditional anthropometrical adjustment (PBW-guided VT)
This is a phase II clinical study to evaluate the safety, tolerability and preliminary antitumor activity of LTC004 in combination with regorafenib in patients with mCRC. A safety introductory trial was conducted to receive LTC004 in combination with regorafenib before starting the formal trial. After completing a 28-day safety assessment, safety will be confirmed before entering the formal trial phase. Further evaluation of the safety and efficacy of LTC004 in combination with regorafenib in the treatment of mCRC
