The presence of high levels of respiratory effort in patients under mechanical ventilation may worsen the adjacent lung injury even after adapting protective ventilation. Primary outcome: To evaluate the failure rate of weaning from IMV and its relationship with the lower and upper extremes of respiratory effort and the upper extreme of dynamic pulmonary stress during the first 7 days of spontaneous ventilation. Analyze the influence of these extremes based on the thresholds of Pocc, P0.1 and their derivatives Pmus, Ptp, din and MP: in relation to days off MV (in the 28-day interval); Total weaning time; Rate and time for tracheostomy; Length of stay in the ICU and hospital; In-hospital mortality rate. CAAE: 78185823.4.0000.5249. Prospective observational study, carried out in the ICUs of Hospital Glória D'or, from January 2024 to July 2026, in patients over 18 years old, undergoing orotracheal intubation and IMV, in their first 7 days on spontaneous ventilation. Hypothesis: Extremes of respiratory effort and dynamic pulmonary stress would be associated with a higher rate of weaning from IMV, as well as longer time on IMV and subsequent longer hospital stay.
Functional dyspepsia refers to a chronic digestive system disease with upper abdominal symptoms originating from the gastroduodenal region, and after clinical examination, including upper gastrointestinal endoscopy, the organic diseases causing the above symptoms are excluded. According to Rome IV standard, functional dyspepsia can be divided into two categories: postprandial discomfort syndrome and epigastric pain syndrome. FD not only seriously affects the quality of life of patients, but also causes a heavy social and economic burden. Therefore, active prevention and treatment of FD, especially PDS, has become an unavoidable problem in clinic. Epidemiological investigation shows that about 30% FD patients have many negative emotions such as sleep disorder, anxiety and depression, and many anti-negative emotional drugs themselves can cause gastrointestinal side effects, which are considered to be the key reasons for the recurrence of symptoms. In recent years, people have paid more and more attention to the brain-gut axis. Microbial-intestinal-brain axis can also affect brain function by releasing neurotransmitters and inflammatory mediators. In addition, the interaction between bile acids and intestinal microflora may also affect the normal function of the intestine. However, the relationship between specific bile acids, microflora and functional dyspepsia is still uncertain. At present, the effective and safe treatment methods for FD with sleep disorder are still very limited. In recent years, auricular point pressing bean therapy has obvious advantages in treating FD with sleep disorder. This study plans to study the clinical efficacy and mechanism of auricular point stimulation on functional dyspepsia with sleep disorder. Provide more treatment methods and ideas for clinicians, popularize and apply green diagnosis and treatment methods, bring good news to more patients, and produce remarkable economic and social benefits.
A randomized placebo-controlled clinical trial to evaluate efficacy of hyaluronic acid in prevention of acute radiation proctitis among oncology patient population especially who are diagnosed with abdomeno-pelvic tumors and subsequently required radiotherapy.
This clinical imaging substudy will use the small molecule translocator protein (TSPO) ligand, Fludeoxyglucose(18F)-labeled DPA-714, to compare neuroinflammation in individuals with high or low grade asymptomatic carotid artery stenosis (aCAD) who are participating in the separate Neuroinflammation in Asymptomatic Carotid Artery Disease study lead by Dr. Ron Lazar (IRB-300007806). The positron emission tomography (PET) tracer [18F]DPA-714 binds to the 18 kDa translocator protein (TSPO, also known as the peripheral benzodiazepine receptor) in the mitochondria of activated microglia/macrophages and provides a non-invasive measure of neuroinflammation.
Adult medulloblastoma is a rare tumour. The "standard risk " group (complete surgery or residual tumour lower than 1,5 cm2, absence of malignant cells in the cerebrospinal fluid, absence of metastasis, absence of MYC amplification and exclusion of large cells medulloblastoma) concerns, for the adult population, a majority of patients at diagnosis (about ¾ of cases). Conventional treatment is classically based on a 54/36 Gy cranio-spinal radiotherapy (54 Gy on the posterior fossa and 36 Gy on the nevraxis). This treatment is associated with an acute toxicity (haematological, cutaneous, digestive and general) wich decreases gradually when patient goes away from the treatment period. For this category of patients and this modality of treatment, The French intergroup experience, pleads in favour of a late and progressive neurotoxicity. This neurotoxicity is associated with a clear degradation of the quality of life. In the light of paediatric studies : We propose a phase II study to estimate the interest of a decrease of radiation doses compensated by a chemotherapy according to the following schedule 1. carboplatine + etoposide based chemotherapy every 28 days x 2 2. followed by, less than 80 days after the surgery, radiation therapy with 24 Gy on the in toto neuro axis and 54 Gy on the post operative bed. The majority of French centres concerned with the neuro-oncology are involved in this trial. About 25 new cases by year are waited. A centralized analysis of pathological slides and of the pre and post surgery Magnetic Resonance Imaging is foreseen. The main objective is to estimate the survival without disease at 1 year Secondary objectives associate the evaluations of the rate of complete response at the end of procedure, the overall survival, the survival without disease, the survival without events, the neurocognitiv toxicity, the endocrine toxicity, the hearing toxicity and the time until definitive deterioration of the quality of life Associated studies Two associated studies are besides foreseen (parallel search for co-financing): 1. A biologic study is planed with the aim to confirm, by morphological, genomic and transcriptomic studies, the interest, for the adult population, of the prognostic markers used in paediatric population 2. A radiological study is planed with the aim to estimate the interest : - of a multimodal follow-up (spectroscopy and perfusion imaging) for the premature detection of recurrences - of the study of functional connectivity in correlation with the neuropsychological follow-up for the analysis of the aetiology and premature markers of neurotoxicity.
Obesity is significantly higher in specific ethnic groups and, in particular, Hispanics. There is an urgent need to implement culturally-sensitive lifestyle interventions and educational programs to decrease the burden of obesity and obesity-related metabolic diseases in Hispanic populations. Accordingly, our overreaching goal is to tailor an existing and successful community-based program, Abriendo Caminos, to leverage effectiveness in promoting healthy nutrition and life-style behaviors among low income, low literacy Hispanic-heritage families. Our multi-function integrated project proposes to (a) adapt Abriendo Caminos for 6-18 year-old children from Mexican and Puerto Rican heritage in five different locations (California, Illinois, Iowa, Puerto Rico, and Texas) and (b) Train existing professionals (in Extension and community agencies) and future professionals (Hispanic university students) to meet the specific needs of this population. Our central hypothesis is that participation in a 6-week community-based program will prevent childhood obesity/maintain healthy weight by significantly increasing: (a) healthy dietary behavior patterns and basic knowledge of nutrition; (b) physical activity levels; and (c) the organization of collective/shared family mealtimes. The implementation of this culturally sensitive, workshop-based curriculum in different regions across the country will help to train the next generation of professionals in Extension and communities to deliver programs that meet the needs of Hispanic families. The integration of Hispanic college students in program implementation via an experiential learning course will further strengthen the program, as well as increase recruitment and retention of Hispanic students, increasing the capacity of Hispanic communities to meet their own needs in the future.
Pulmonary embolism (PE) remains a diagnostic challenge. False negative testing exposes patient to the risk of potentially fatal recurrence. False positive testing exposes patients to potentially fatal unduly side effects of anticoagulants. Current diagnostic strategies rely on the sequential use of pretest clinical probability, Ddimer test, and chest imaging. Two chest imaging modalities have been validated for PE diagnostic exclusion: Computed Tomography Pulmonary Angiography (CTPA) and planar V/Q scan. Main limitations of planar V/Q are the high proportion of non-conclusive results, therefore requiring additional testing and more complex diagnostic algorithms. Main limitations of CTPA are its higher radiation dose and contraindications (renal failure). In a randomized trial that compared strategies based on CTPA and on planar V/Q scan, a 30% increase in the rate of PE diagnoses was found in the arm using CTPA, raising the hypothesis of over-diagnosing and over-treating PE when using CTPA. V/Q Single Photon Emission CT (SPECT) is a new method of scintigraphic acquisition that has been reported to improve the diagnostic performances of the test, which could reduce the number of non-conclusive tests and allow simplified diagnostic algorithms. The investigators hypothesize that a strategy based on V/Q SPECT could be an alternative to the two usual approaches responding rightly to the two mains issues and combining the advantages of CTPA (simplified diagnostic approach) and planar V/Q (no overdiagnosis, lower radiation exposure, no contraindication). Although a recent survey showed that up to 70% of nuclear medicine centers perform SPECT rather than planar imaging for diagnosing PE, a diagnostic management outcome study, in which diagnostic decision would be made on the basis of a standardized algorithm based on the V/Q SPECT is lacking. Such a study needs to be conducted to ensure that the safety of diagnostic exclusion using a V/Q SPECT based strategy is non-inferior to that of previously validated strategies, and to verify that the use of V/Q SPECT does not lead to over-diagnosis.
This research study is studying two different types of radiation as treatment for brain metastases (tumors in the brain that spread from a cancer that originated elsewhere in the body)
Preterm and very preterm infants are at risk of developing encephalopathy of prematurity and long-term neurodevelopmental delay. Magnetic resonance imaging (MRI) allows the characterization of specific features of encephalopathy of prematurity, including structural changes of brain white matter and gray matter. This study wants to investigate important evidence that early repeated high-dose rhEPO(5250 IU/kg) treatment improves long-term neurological outcomes in very preterm infants and without obvious adverse effects.
In the department for substance use disorders at Uppsala University Hospital there are two wards. One that is locked, where the patients that are emitted can not go out to smoke and another ward where there is a possibility to go out and smoke during the day. The smoking habits on those two floors will be compared and how they feel about smoking will be evaluated when they are admitted to the ward, at discharge, after 1 mont and after 6 months.
