Epigenetics and Protective Factors in the Preterm Infant
Preterm infants (PT) spend their first weeks of life in the Neonatal Intensive Care Unit (NICU) where they are exposed to unfavorable conditions with different effects on child development including long-term alterations in epigenetic regulation (DNA methylation). Recent studies document that these epigenetic changes are associated with behavioral modifications, such …
Perinatal Covid-19 Infection, NO Pathway, and Minipuberty
Some evidence exists that SARS-COV-2 may infect pituitary axis, and therefore may alter hypothalamic function. Whether perinatal COVID-19 is associated with alterations in the maturation of the Hypothalamic-Pituitary-Gonadal (HPG) axis, and specifically with its transient activation occurring during infancy, namely minipuberty, is a major concern. Among the various pathogenic features …
Overture Metabolomics Non-Selection Study
In this study, study investigators will collect embryo culture media on day 5 of vitro fertilization (IVF) culture, prior to vitrification and embryo transfer for testing via Metabolomic screening. Metabolomics is a new, non-invasive method of embryo selection which involves testing discarded embryo culture media for analytes secreted by the …
Intraoperative OCT Guidance of Intraocular Surgery II
The overall five-year goals of the project are to develop novel technology to provide actionable new information through provision of live volumetric imaging during surgery, improving surgical practice and outcomes. The investigators believe this technology will enable novel ophthalmic and other microsurgeries not possible due to current limitations in surgical …
IMMunological resPonse Assessment afteR Acute iSchemic Stroke Treated With Endovascular Therapy (IMPRESS)
IMPRESS study aims to describe the immuno-inflammatory and thrombo-inflammatory profiles during the first 24/36 hours of treatment of patients suffering from AIC treated with TM, and to study the possible impact of these profiles on the functional prognosis at 3 months of AIC treatment.
Occurrence of Radiation-induced Otitis Media in Nasopharyngeal Carcinoma Patients After Intensity Modulated Radiotherapy
This is an observational cohort study to investigate the incidence of radiation-induced otitis media, changes in tubal function and hearing in newly diagnosed nasopharyngeal carcinoma patients without metastasis at multiple time points from baseline to 1 year after radiotherapy.
Regulation of Inflammatory Genes in Hidradenitis Suppurativa
The purpose of this protocol is to examine the cytokine profi le of pati ents with hidradeniti s suppurati va (HS) and idemechanisms responsible for post-transcripti onal regulati on of these genes. The primary objecti ve is to determinfollowing cytokines linked to hidradeniti s suppurati va are diff erenti ally …
Objective Assessment of Behavioral Associations of Patients With Dementia
It is generally acknowledged that patients with dementia are best cared for at home. However, outbursts of various behavioral disturbances, e.g., combativeness, appear in most cases and often necessitate institutionalization. These outbursts are often without apparent warning, which limits preventive interventions. The measurement of the electrical activity of the skin …
NIH RECOVER Tissue Pathology: Understanding the Long-Term Impact of COVID-19
The Post-Acute Sequelae of SARS-CoV-2 (PASC) Autopsy Study is a cross-sectional study designed to define and characterize the epidemiology, natural history, clinical spectrum, and underlying mechanisms of post-acute effects of SARS-CoV-2 infection in a diverse population representative of the general COVID-19 population in the US. The autopsy study will characterize …
Multimodality Imaging in the Screening, Diagnosis and Risk StratifictiON of HFpEF
The incidence of Heart failure with preserved ejection fraction (HFpEF) in Heart failure patients increases rapidly. However, the current clinical awareness is insufficient, and the cardiac structural and functional injury are not well understood. It is difficult to recognize the subclinical changes of the cardiac in the early stage with …
