Observational study Primary Objective: To study whether ECMO alters the PK of anti-infectives including voriconazole, posaconazole and caspofungin in critically ill patients on ECMO Secondary Objectives: Develop Population PK models of anti-infectives, including voriconazole, posaconazole and caspofungin in critically ill patients on ECMO Develop Physiological-Based PK (PBPK) model of anti-infectives, including: voriconazole, posaconazole and caspofungin in critically ill patients on ECMO Study population: Critically ill patients on ECMO Methodology: Observational study to determine whether ECMO alters the PK of anti-infectives, by developing PK models This is a non-interventional descriptive study in that the anti-infective drug selection and dosing will be at the discretion of the clinician, based on the clinical context and unit guidelines. Doses will be reconstituted and administered as per local hospital protocols in line with patient's routine care. Patients will be asked to provide additional blood samples over the course of the anti-infective dosing schedule, these samples will be taken from existing arterial lines to help guide treatment in future patients on ECMO receiving these anti-infectives.

To compare the accuracy of four lens diameter measurement methods and to study the influencing factors of intraocular lens deviation after operation

Prevention of thromboembolic complications is an important part in the management of patients with atrial fibrillation (AF). European and American guidelines recommend the use of non-vitamin K antagonist oral anticoagulants (NOACs) over therapy with vitamin K antagonists (VKA) in most AF patients. The number of patients treated with NOACs has increased significantly during the last few years. In the primary randomized controlled trials leading to their approval, compared to warfarin, NOACs were shown to be either noninferior or superior for stroke prevention in AF, with similar or reduced rates of bleeding, especially intracranial haemorrhage. The aim of this study was to assess the frequency of oral anticoagulants using, espescially apixaban, dabigatran, and rivaroxaban, and the predictors of their prescription in a group of hospitalised patients with AF.

The study will look at the immunological characteristics of COVID-19 patients and determine neutralizing antibodies against SARS-CoV-2 virus.

BACKGROUND: Chiari I malformation is a rare disease characterized by cerebellar amygdalae descent under the level of the foramen magnum. It causes troubles in cerebrospinal fluid circulation and direct compression on brainstem, producing characteristic headaches, neurological impairment and syringomyelia. Surgery is the only treatment, indicated when symptomatology exists. However, sometimes patients complaint about atypical symptoms that are difficult to interpret. We would like to study one of these atypical symptoms, gait imbalance, in a pediatric population thanks to a computerized dynamic posturography (Equitest®). METHOD: infants from 6 to 18 years of age presenting a radiologically confirmed Chiari I malformation will be included in the study. We will compare posturographic results of patients which will be operated on with the results of the patients which will not; furthermore, we will compare preoperative and postoperative results in operated patients. RESULTS: 19 patients have been enrolled in the study, and data have been collected for 12 of them. Seven patients belong to operated population. CONCLUSIONS: even if enrolment of the patients is satisfactory, disposable data are not enough to perform statistical analysis and to put forward any conclusion.

The study will be carried of scanning the database of 296 individuals with cerebral palsy followed in the university pediatric rehabilitation clinic. Cerebral palsy risk factors and demographic information will be obtained from the database. The data will be classified according to date of birth, divided into 3 groups: those born before 2000, those born between 2000-2010, and those born after 2010.Changes in cerebral palsy risk factors will be investigated at 10-year intervals.

The investigators will study nasopharunx microbiota composition, RNA sequences and in vitro cytokines production by peripheral blood cells of COVID-19 patients (both mild-moderate and severe cases) (comparing with convalescent patients and healthy controls).

Find out the deciding factor(total body weight, corrected body weight, ideal body weight, fat-free mass, body mass index, skeletal muscle mass, body fat) of neuromuscular blocker dose for deep neuromuscular blockade in bariatric surgery.

The purpose of this research study is to examine the relationship between personal characteristics and satisfaction with care in those diagnosed with Parkinson's disease during the COVID-19 pandemic. Participants will take 4 different surveys regarding their satisfaction with care throughout the duration of the COVID-19 pandemic. The surveys in total should not take more than 30 minutes to complete

Before cataract surgery, subjects in the observation group used iTrace ocular aberration analyzer（itracey Technologies）and IOL-Master 700 biometer to measure the preoperative DLI(Dysfunctional lens index) and SS-OCT image of the lens, and The researchers used the anterior segment slit lamp to take photos of the anterior segment of the subject's lens in a state of dilated pupils .and self-scoring of the preoperative visual quality assessment scale. Healthy subjects in the control group also need to complete the above inspections. After that, three experienced cataract specialist surgeons combined the preoperative optometry data of each subject, the photos of the LOCS III anterior segment and the Catquest-9SF questionnaire score to determine whether each subjects should undergo cataract surgery. The subjects were divided into cataract surgery group and non-surgical group. Finally, statistically study the correlation between the DLI index and the degree of lens opacity that has been collected, and use the ROC curve to calculate the DLI as the best cut-off point of DLI to distinguish whether to perform cataract surgery.
