Time - Lapse Analysis of Frozen Embryos
A retrospective analysis of embryo defrost cycles that were rated in the EmbryoScope system and frozen will be performed. The study will examine the possible association between the morphokinetic grading received by these embryos as fresh embryos before freezing, and their survival, the morphological grading they received after thawing, their …
Impact of Hypothalamic Gliosis on Appetite Regulation and Obesity Risk in Children
BEAM is a multi-site longitudinal cohort study of hypothalamic gliosis, central regulation of appetite and weight gain in children. Participants will be recruited from the community in the greater Seattle and greater Baltimore area. All participants will consent to enroll in the 24-month study during which they will complete 5 …
Sputum Studies of Anti-Citrullinated Protein Antibodies (ACPA) and Rheumatoid Arthritis (RA) Origins
The study is designed to learn more about the causes of rheumatoid arthritis (RA). People who get RA have elevated protein markers called autoantibodies in their blood years before initial symptoms of arthritis. The goal of this study is to learn more about how autoantibodies in RA might be related …
Fibroids and Infertility - a Study of the Significance of Removal of Fibroids With Regard to Endometrial Receptivity
We aim to explore some of the molecular factors that reduce fertility for women with leiomyomas, taking into account leiomyoma location, size, number and vascularity. Tissue samples from the endometrium and leiomyomas will be obtained during the mid secretory phase before and 3-6 months after surgical excision for a comprehensive …

Height-based Formula for Predicting the Insertion Depth of Left-sided Double and the Role of Fiberoptic Bronchoscopy
The use of height based formula to predict insertion depth of left-sided double lumen tube in thoracic surgery is now well established. The investigators have developed a formula to be used and published recently. The investigators verified the formula with the use of FOB. This observational study we are going …
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 …
Percentage Visualized Mucosa as a Marker for the Quality of Colonoscopy
Primary hypothesis: The percentage of mucosa visualized during the withdrawal of a colonoscopy with reference to the position in the colon by means of the scope-guide is an appropriate parameter for assessment of the quality of colonoscopy and correlates with the probability of the detection of adenomas. Secondary hypothesis: The …
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 …
