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 …
Pediatric Ultrasound-guided Dorsal Penile Nerve Block Plus Sedation in Spontaneous Breathing
One of the most frequent surgical procedures in the pediatric population is circumcision, following which postoperative pain could be stressful. Usually, the most common approach is combining regional anesthesia techniques such as landmark dorsal penile nerve block (DPNB) with general anesthesia (GA). The hypothesis of this study investigates ultrasound-guided DPNB …
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 …

This study focuses on the treatment for complicated diverticulitis classified as Hinchey I-IV. The aim of this prospective observational study is to evaluate type of treatment and the success rate of treatment in acute complicated diverticulitis (ACD) at participating hospitals in Sweden and Norway. Furthermore, the effects on quality of …
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 …
