Filter by:Background: Reverse triggering (RT) is a frequent phenomenon observed in sedated patients under a mechanical ventilation mode called assist-control ventilation. RT is when the ventilator would trigger the patient's respiratory effort instead of the correct order of the patient's respiratory effort triggering the ventilator. Reverse triggering can have negative consequences (loss of protective lung ventilation, and causing double breaths - with the ventilator giving two consecutive breaths and not allowing the patient to exhale) but also offer some protective effects (avoid diaphragm disuse atrophy). The balance of its negative vs positive effects depends on its frequency and magnitude of its associated respiratory effort. Respiratory entrainment is the most often referred mechanism involving a change in patient's rate of breathing effort from that of patient's intrinsic rate to the rate of mechanical insufflation. The specific ventilatory settings associated with or responsible for RT remains unknown. Aims: To assess in mechanically ventilated critically ill patients the influence of the set respiratory rate (RR) and tidal volume (Vt) on the presence/development of RT and to describe the pattern of respiratory muscle activity during Reverse Triggering (RT). Methods. 30 adult patients (15 in each group), sedated and under assist-controlled ventilation will be included. Ventilator settings will be modified to modulate the frequency and magnitude of reverse triggering. Initially, with the ventilator on a mode called volume control, which means the ventilator controls the amount of air (tidal volume) and the number of breaths the patients gets every minute (respiratory rate [RR]). The tidal volume will be set at the current standard clinical practice setting (6 ml/kg of predicted body weight). The presence of an intrinsic respiratory rate will be assessed with an end-expiratory occlusion maneuver. Next, the number of breaths the ventilator gives per minute (RR) will be changed from 6 breaths less to 6 breaths more, in steps of 2 breaths every minute. The protocol will be repeated again changing the amount of air the patients gets (tidal volume) from 4, 5, 7 and 8 ml/kg. Continuous recordings of airway pressure, flow, esophageal pressure, electrical activity of the diaphragm, main accessory muscles and frontal electroencephalography will be obtained during the protocol and baseline clinical and physiological characteristics and outcomes will be recorded. A validated software will be used to detect RT and measure the intensity and timing of each muscle electrical activity and the magnitude of the inspiratory effort during RT.
In this study, investigators wanted to determine the effect of T2DM susceptibility gene mutations on self-expression. Participants (T2DM patients and controls) were recruited to identify genotypes and detect the levels of T2DM susceptibility genes expression in the fresh peripheral plasma. The normal pancreatic tissues or adjacent tissues of pancreatic cancer were also collected to identify the expression differences of T2DM susceptibility genes under different genotypes.
This is a retrospective cohort study of patients with T2DM who were treated with exenatide twice daily as a part of their diabetes care for at least 12 months. The objective of this study is to investigate the influence of T2DM susceptibility gene polymorphisms (NOS1AP, KCNQ1, TCF7L2, WSF1, GLP-1R, etc.) on the efficacy of GLP-1 RA (exenatide, liraglutide, etc.), to identify the variables that can predict the efficacy of GLP-1 RA, and to evaluate the weight of these variables on the efficacy.
This project aims to introduce solutions for strengthening the management capabilities of two types of patients, in terms of care and prevention. Specifically, it is aimed at neurological patients with mild or minor neurocognitive decline (Mild Cognitive Impairment, MCI) and endocrinological patients diagnosed with obesity. The study want to enhance the predictive capacity of the care process management system through an Artificial Intelligence (AI) system. All patients diagnosed with MCI and obesity who, within 30 months, will be referred to the Neurology and Endocrinology clinics of the IRCCS Centro Neurolesi Bonino-Pulejo in Messina will be evaluated. Study design Patients will not be subjected to any procedure that goes beyond normal clinical practice; the clinical and neuropsychological variables that will be collected for the study are those that are commonly collected in normal clinical practice. All patients diagnosed with MCI and obesity who, within 30 months, will be referred to the Neurology and Endocrinology clinics of the IRCCS Centro Neurolesi Bonino-Pulejo in Messina will be evaluated. All patients will undergo clinical, neuropsychological and psychological evaluation at the beginning (baseline T0), at the end (T1) and after ... months from the end of treatment (follow up T2).
This is a non-interventional, prospective, single-center study designed to collect and describe environmental and psychosocial data from patients with a history of male breast cancer (MBC) referenced in the IUCT-O regional database. The study will be conducted on a population of 110 to 150 patients.
Sepsis is a disruption of homeostasis in the human body in response to bloodstream infection and is associated with a high risk of mortality. Worldwide, sepsis is affecting approximately 30 million people and resulting in six million deaths. Blood culture is a specific blood sample used to identifying microbial agent (bacterium or yeast) and determine the sensitivity of these microorganisms to antibiotics and antifungals. Any delay in identifying the microorganism and/or determining the AST (antibiotic susceptibility testing) has a direct impact on the administration of appropriate antibiotic treatment and, consequently, on mortality of the patient. The faster the diagnosis, the faster the antibiotic treatment will be adapted, the higher the survival rate/probability of patients, and the lower the ecological impact. In routine, clinical microbiology laboratories currently use 2 automatized techniques: MALDI-TOF MS® for microorganisms identification and VITEK2® method for AST determination. Based on a proteomic approach, the IDBIORIV method is a rapid method (90 minutes) in comparison of current methods (24/48 hours) able to identifying a large panel of 113 pathogens and determine the antibiotic resistance profile of 49 species for 4 classes of antibiotics (Beta-lactams, Aminosides, Glycopeptides, Colistin). The main objective of this study is to evaluate the performance of the IDBIORIV method in pathogen identification and antibiotic susceptibility testing in comparison with current methods of analysis of positive blood cultures used at the microbiology laboratory of the Hospices Civils de Lyon, in a real clinical situation, over a 2-year period.
The goal of this intervention development and pilot clinical trial is to determine whether receiving the brief online intervention results in greater reductions in past 7-day e-cigarette use frequency and smoking susceptibility over an 8-week period compared to receiving the control condition in young adults who currently use e-cigarettes. Participants in the experimental condition will be asked to complete the 30-minute mobile-based program. Participants in the assessment-only control will be given the option to access the intervention after they complete their final survey at 8 weeks. All participants will complete our online surveys at baseline as well as 2-weeks, 4-weeks, and 8-weeks post-randomization. Researchers will compare outcomes among the intervention and control groups to determine the efficacy of the intervention.
The study is a real-world observational clinical study. Patients diagnosed as colorectal cancer through histopathology were screened and enrolled. Before anti-tumor treatment, colonoscopy biopsy tissue specimens, surgical specimens, and malignant pleural effusion or ascites specimens, etc. are collected. The investigators will perform a drug sensitivity testing based on a novel drug susceptibility testing method to test the commonly used anti-tumor treatment regimens. Patients were given conventional anti-tumor treatment according to the medical judgment of the doctors. Finally, the investigator will evaluate the consistency of clinical efficacy in colorectal cancer treatment and drug susceptibility outcomes.

Background: Runt-related transcription factor 1 (RUNX1) gene regulates the formation of blood cells. People with mutations of this gene may bleed or bruise easily; they are also at higher risk of getting cancers of the blood, bone marrow, and lymph nodes. Objective: To test a drug (imatinib) in people with RUNX1 mutations that cause symptoms. Eligibility: Adults aged 18 and older with RUNX1 mutations. Healthy people without this mutation, including family members of affected participants, are also needed. Design: Participants with the RUNX1 mutation will be screened. They will have a physical exam with blood and urine tests. They will have a test of their heart function. They may need a new bone marrow biopsy: A sample of soft tissue will be removed from inside a bone. Imatinib is a tablet taken by mouth once a day, every day, at home. Affected participants in different parts of the study will take imatinib for either 28 days or up to 84 days. Participants will visit the clinic once a week for the first 28 days that they are taking the imatinib. Then they will come once every 2 weeks if they are taking the drug for 84 days. Blood, urine, and tests of heart function will be repeated. They may opt to have the bone marrow biopsy repeated after they finish their course of imatinib. Participants will have a follow-up visit 30 days after they stop taking imatinib. Participants who do not have the RUNX1 mutation will have 1 clinic visit. They will have blood tests. They will fill out questionnaires. They may opt to have a bone marrow biopsy....
