The primary purpose of this study is to identify and develop biomarker signatures based on circulating micro ribonucleic acid (RNA) in the blood and on exhaled volatile organic compounds (VOC) in the breath associated with high risk of pulmonary hypertension (PH) to assist in the diagnosis of PH; to estimate the sensitivity, specificity, positive predictive value, and negative predictive value of the biomarker signatures in identifying participants with PH by comparing the biom...
By integrating approaches from the physical, biological, computational, statistical and clinical sciences, this study will test the hypothesis that early diagnosis of subclinical signatures of critical illness encoded within physiological signals complements conventional clinical predictors by providing unique prognostic insight. Early diagnosis of these subclinical signatures may lead to earlier treatment that can save additional lives. Our goal is to validate predictive algor...
The goal of this clinical research study is to learn if using "gene signatures" can be an effective way to decide the best treatment for breast cancer patients. Gene signatures may be able to help researchers predict who will respond to chemotherapy given before surgery.
The purpose of this study is to assess the validity and usefulness of omics signatures for improved identification and risk stratification of patients with endocrine hypertension and stratification of patients with primary hypertension.
The purpose of this study is to further clarify existing research on the early identification and documentation of suspected deep tissue injury (sDTI). Basic principles of physiology along with prior research suggests that sDTI has quantifiable amounts of heat (or lack thereof) relative to surrounding tissue that will exhibit characteristic thermal signatures (temperature). These signatures will be measured and quantitatively recorded using long-wave infrared thermography (LWIT...
This study is designed to see if doing regular training on a spatial imagery task leads to improvements in the ability to do the trained spatial imagery task and in the ability to get around in everyday activities.
This study will prospectively collect airway, stool, and blood samples on 80 subjects with lung cancer undergoing immunotherapy. Investigators will evaluate airway/stool microbial signatures associated with local (lower airway) and systemic (blood) immune tone.They will then study whether microbiota and/or host signatures predict subjects' response by longitudinal assessment of the progression free survival. They will also repeat sampling after 8 weeks of immunotherapy to expan...
Although gastroenteropancreatic neuroendocrine neoplasia (GEP-NEN) were considered for years as rare tumors, their incidences are increasing. Due to their potential of early metastases and their heterogenous response to therapy, these tumors are important clinical entities. A major problem remains the impossibility to adequately predict tumors' response to treatment, precluding an individualized therapy. Further, there is no method to efficiently screen these tumors. Protein ba...
Investigators plan to use modified TTMB technology to puncture prostate of participants suspected prostate cancer, especially those with the first negative biopsy , but having a rising PSA.Then, Investigators will simulate the spatial distribution of prostate cancer in patients with positive biopsy before radical prostatectomy by way of the TPS software system . And after the radical prostatectomy ,Investigators will simulate the spatial distribution with the help of large tiss...
Prospective, open, randomized, parallel, two-arm trial to compare the clinical pregnancy rate between most commonly used two embryo transfer techniques: trial followed by transfer technique and afterloading technique
This study will assess whole brain samples from glioblastoma patients at autopsy to determine the underlying pathological signatures of tumor treatment fields at autopsy.
The purpose of this study is to determine whether vestibular disorders could affect visuo-spatial cognition. Visuo-spatial cognition will be evaluated using a new computerized test using a digital tablet.
The purpose of this study is to compare IVF outcomes between day 3 and day 5 embryo transfer in patients with five or fewer embryos in a fresh embryo transfer in vitro fertilization (IVF) cycle. Information derived from this trial would allow us to maximize the chances of success for these patients undergoing IVF.
Patients with peritoneal metastasis of colorectal or high grade appendiceal origin who are candidates for cytoreductive surgery with HIPEC (hyperthermic intraperitoneal chemotherapy) will be enrolled in this study. Blood collection for measurements of plasma cell-free DNA hydroxymethylation signatures will be performed at different time points, before and after surgery, in order to determine if plasma hydroxymethylation signatures are more sensitive than conventional tumor mark...
We plan to use this platform to map biochemical signatures in unmedicated schizophrenic patients prior to and 4 weeks post treatment with the antipsychotic drug aripiprazole and compare that to lipid perturbations induced by risperidone. These drugs have inherently different risk for metabolic adverse effects and patients respond to them differently. Metabolic signatures for the drugs capture significant biochemical information that could explain part of the basis for varied dr...
20 healthy man, 10 in trial group and 10 in control group (randomly divided) will participate in the experiment on order to evaluate if improvement in physical fitness influences spatial learning in humans.
Dermal transfer efficiency has been defined as the amount of material that moves from one surface to another following contact. The investigators propose to measure dermal transfer efficiency for the following pathways: (1) object to skin, (2) skin to skin, (3) skin to mouth, (4) clothing to skin, (5) gloves to skin, and (6) air to skin. First, the quantitative dermal transfer will be measured for the two selected test substances (lead, Tinopal) for each of these six pathways....
When only one embryo is available after in vitro fertilization, the option is to transfer either day 3 or day 5. There is no randomized trial compared the day 3 to day 5 for this subgroup.
This is a prospective cohort study. All patients presenting for periprosthetic joint infection and requiring debridement only or resection arthroplasty will be eligible. The synovial joint fluid will be sampled before the arthrotomy at the operation room. The purpose of this study will be to evaluate that 1) the concordance of organism identification by the direct identification of MALTI-TOF MS versus routine identification of MALTI-TOF MS and conventional cultures and 2) the ...
Cervical cancer is one of the major health problems for chinese women. Besides surgery and radiotherapy, neoadjuvant chemotherapy has been proved to be an effective program by many studies. However, not all patients respond well to neoadjuvant chemotherapy. Knowing the therapeutic effect of the neoadjuvant chemotherapy before receiving it can not only reduce the economic burden, but also more importantly save time to take more suitable treatments. This study is undertak...
The purpose of the study is to collect physiologic data streams with the Accuryn Monitoring System and validate the accuracy of these measurements against existing gold standards, and to track and analyze changes in these physiologic data streams to identify clinical signatures that may enable earlier diagnosis and intervention of critical conditions.
The objective of the present randomized controlled study is to compare clinical effectiveness and safety of freezing all embryos followed by frozen-thawed embryo transfer (FET) compared to fresh embryo transfer, in women undergoing IVF treatment.
Neuroplasticity-based approaches seem very promising to maintain cognitive health in older adults and postpone the onset of cognitive-decline and dementia symptoms. The aims of this project are threefold: 1. the evaluation of the effects of a neuroplasticity-based-cognitive randomized computer-based intervention consisting in training with non-action video games on brain and cognitive functions that decline with ageing, including attention and spatial wo...
The increasing use of FET emphasizes the importance of preparing and timing the endometrium in FET cycles, however there is no consensus on luteal phase progesterone supplementation in mNC-FET and the optimal day of blastocyst warming and transfer. The aim of this multicenter RCT is to assess the effect of progesterone supplementation in hCG-triggered mNC-FET and the effect of embryo thawing and transfer at hCG+6 or hCG+7 days, respectively. In total 604 patients will be includ...
