Correlation Between Specific Gene Mutationand Local Immune Microenvironment and Immunotherapy Efficacy in NSCLC
Immunotherapy for PD-L1 positive patients is still ineffective in some patientswhich may be related to the complex immune microenvironment.In view of this bottleneck, further refinement of immunotyping and in-depth study of drug resistance mechanism are the most important tasks. In this observational study, we evaluated the difference of gene mutation …
Laryngomicrosurgery Under NIDP General Anesthesia Supported by THRIVE
Laryngomicrosurgery requires deep paralysis and general anesthesia to finish the procedure. After the procedure, patients need a long time to recover. In the present study, with the support of the transnasal humidified rapid-insufflation ventilatory exchange, laryngomicrosurgery would be finished under nonintubated deep paralysis (NIDP) general anesthesia. In this case series …
Risk of Recurrence of Cervical Artery Dissection During Pregnancy and Puerperium
Cervical artery dissection (CAD) accounts for about 2% of all strokes, and is a major cause of stroke in young people (about 15%). Many cases of CAD during pregnancy and puerperium have been described, suggesting that pregnancy and puerperium may be potential risk factors for CAD. The purpose of this …
Retrospective Chart Review Study of Patients With PIK3CA-Related Overgrowth Spectrum Who Have Received Alpelisib
The study is a site-based retrospective non-interventional medical chart review of pediatric and adult male and female patients with PIK3CA-Related Overgrowth Spectrum (PROS). Patient-level data are abstracted from medical charts of all eligible patients at all participating sites. Information from patients treated with alpelisib will be used to describe the …
Non-specific Back Pain and Spinal Manipulation
The main purpose of this study is to identify short-term predictors of positive responses to a spinal manipulation treatment. To do this, positive responses to treatment, characterized by improvement in pain score, functional capacity, as well as the global perceived change will be evaluated using single and multiple logistic regressions …
Soluble ST2 and Cardiovascular Outcome
Cardiac surgery induces hemodynamic stress on the myocardium, and this process can be associated with significant cardiovascular morbidity and mortality. Soluble suppression of tumorigenicity 2 (sST2) is biomarker of myocardial remodeling and fibrosis; however, little is known regarding their potential association with cardiovascular events. This study aimed to investigate the …
The Influence of Two Different CO2 Absorbers on Sevoflurane Consumption During Anaesthesia
Traditional sodalime CO2 absorbers are known to not only react with CO2 but also with sevoflurane. Therewith, a potentially harmful compound (compound A) is formed that can be nephrotoxic. In the United States, the sevoflurane manufacturer therefore recommends keeping the FGF (FGF) at >2.0 L min-1 if a sodalime CO2 …
Antigen Presentation and Lymphocyte Response in Parkinson's Disease
The way the immune system responds to certain PD-related proteins in PD donors compared to the way it responds in persons without or fewer PD related proteins is not well studied and this study aims to analyze the autoimmune response in each group. The study involves a one time visit …
Molecular Characteristics of Gastroesophageal Adenocarcinoma (MOCHA): A Prospective Feasibility Study
Researchers are looking to further our knowledge on disease biology and treatment selection for gastroesophageal adenocarcinoma. The purpose of this study is to see how useful it is to look for changes and characteristics in your genes (molecules that contain instructions for the development and functioning of the cells) and …
An Observational Cohort Trial of Outcomes and Antibody Responses Following Treatment With COVID19 Convalescent Plasma in Hospitalized COVID-19 Patients
This is an observational study designed to learn more about how COVID19 convalescent plasma works in patients with COVID19 compared to those patients who did not receive convalescent plasma treatment. Information about patient recovery will be collected from participants' electronic medical records to evaluate safety, clinical outcomes, and SARS-CoV2 antibody …
