The purpose of the study is to evaluate the temperature measurements by the Prizma device.
The anesthetized patient is turned to the prone position during lumbar spine surgery. The dynamic compliance of lung usually decreases and peak airway pressure increases during the surgery. A new ventilation mode, pressure-controlled ventilation with volume guaranteed mode (PCV-VG) has been recently introduced. The ventilator compares the tidal volume of the previous breath and automatically regulates the pressure up or down to achieve the set tidal volume. This prospective, randomized study is designed to compare the effect of PCV-VG and volume-controlled ventilation (VCV) on peak airway pressure, lung compliance and hemodynamic variables.
Tumors of the central nervous system affect 21 people per 100,000 every year, a figure that refers to countries with advanced economies, with an increase in incidence over time. Experimental evidence suggests that cancer stem cells (CSCs) may play a key role in the malignancy of these tumors. In fact, due to the hypoxic tumor microenvironment, these cells are able to create compensatory pathways that confer stem-like, angiogenic and pro-tumoral functions. Furthermore, it has been demonstrated that brain tumor stem cells are radio- and chemo-resistant and therefore not treatable with the therapeutic protocols currently in use. To date, in fact, there are no definitive treatments for the eradication of brain tumors. In this scenario, sphingolips, a class of lipid deputized to several physiological functions, are also involved in tumor onset, progression, drug resistance, and aggressiveness. In hypoxic tumor microenvironment, CSCs present a modified rheostat in the metabolism of sphingolipid, in favor of Sphingosine-1-phosphate (S1P). S1P is an intermediate of sphingolipid metabolism, formed from sphingosine through the action of sphingosine kinases (SK). Increasing evidence suggests that S1P acts as a tumor-promoting signal, predominantly in the extracellular environment, regulating important cellular properties correlated with tumor potential. The project aims to identify new molecular and metabolic targets involved in the survival and chemo-resistance of tumor stem cells in relation to the tumor microenvironment.
Hypertension is the major risk factor for cardiovascular and cerebrovascular diseases worldwide. The escalating prevalence of inadequate sleep now parallels that of hypertension. Observational and experimental evidence favoring a causal relation between insufficient sleep and hypertension are particularly compelling - sleeping 6 hours or less per night is associated with a 20-32% higher probability of incident hypertension. Since sleep curtailment is largely voluntary, sleep deficiency may be corrected and the detrimental health consequences potentially reversed. In this study the investigators aim to investigate the effects of 8 weeks of sleep enhancement/extension vs health education in prehypertensive and stage 1 hypertensive subjects who report habitual short sleep (≤6.5 hours/night).
Intermittent hemodialysis/diafiltration is a current renal replacement therapy (RRT) institued for ICU patients with AKI. For a better clinical tolerance, iinternational guidelines advise to use cold dialysate, increase duration session, decrease blood and dialysate flows, and increase level of sodium dialysate concentration (≥ 145mmol/l). Indeed, the use of a Na concentration dialysate > 145 mmol/l improves intradialytic hemodynamic tolerance but it may also induce fluid overload by the transfert of sodium from the dialysate compartment to the blood. Yet, fluid overload has been strongly associated with mortality in critically ills. The investigators hypothesized that the use of a level in sodium dialysate at 140 mmol/l with slow low efficiency daily dialysis-filtration (SLEDD-f) will permit a fair intradialytic hemodynamic tolerance without the adverse effect of intradiaclytic Na loading from the dialysate. Two randomized groups of ICU AKI patients treated by SLEDD-f will be compared in terms of intradialytic hemodynamic tolerance and overload accordong to 140 or 145 mmol/l of Na in the dialysate
This is a randomized multicentre study in patients with high-risk MIBC to investigate adjuvant radiotherapy after radical cystectomy and pelvic lymph node dissection. The objective of the study is to provide evidence that adjuvant radiotherapy improves loco-regional control with potential benefits in survival. The study will also evaluate the quality of life of patients and the tolerance of the treatment.
This study evaluate the safety and tolerance of MASCT-I(multiple-antigen specific cell therapy) combined with PD1 antibody in patients with advanced gastric cancer who failed in first-line chemotherapy. The study is divided into three stages: the first, second stage is the stage of the dose climbing, and the third stage is the dose expansion stage. The patients would be treated with MASCT-I single drug therapy, MASCT-I+ low dose PD1 antibody therapy, and MASCT-I+ high dose PD1 antibody therapy.
This is a single centre exploratory study that aims to apply hyperpolarized xenon-129 (129Xe) magnetic resonance imaging (MRI) methods and measurements in individual patients with and without lung disease to better understand lung structure and function and evaluate response to therapy delivered as a part of clinical care.
The purpose of this study is to determine whether a lung transplantation prior to bone marrow transplantation (BMT) would allow for restoration of pulmonary function prior to BMT, allowing to proceed to BMT, to restore hematologic function.
The treatment of Behavioural and Psychological Symptoms of Dementia (BPSD) continue to raise difficult problems. Both the pharmacologic and non-pharmacologic therapies often fail to achieve the expected results. The aim of this study is to assess the short- and long-term efficacy of an intervention, the Special Care Unit for patients with BPSD (SCU-B), already implemented in some countries but not validated so far, as well as its cost-effectiveness
