The Human Observatory Study is a prospective observational and ecological surveillance study building a continuously-updating world model for human health, disease, and death at the individual and population level. Individual multi-system clinical data from enrolled participants are linked to a continuously-ingested ecological data infrastructure spanning environmental exposures, social determinants, genealogical and family history records, mortality data, and population health databases at geographic resolutions from home address to global scale and beyond. The resulting model generates individual screening recommendations informed by population-level causal estimates, and population-level causal forecasts anchored by present-timepoint individual clinical biology. This linkage creates a feedback architecture designed to improve both simultaneously.

This study is testing an investigational inhaled migraine medication to see how well it works, how safe it is, and how well people tolerate it. Adults with migraine will receive both the study medication (ASY202) and a placebo (inactive treatment) at different times during the study. Neither participants nor study staff will know which treatment is given at the time. The medication is taken using a handheld dry powder inhaler to treat migraine attacks when they occur. Following screening, eligible participants will be enrolled and randomized to one of two treatments sequences i.e. one treatment sequence will receive ASY202 in treatment period 1 followed by placebo in treatment period 2 and other treatment sequence will receive placebo in treatment period 1 followed by ASY202 in treatment period 2. The study lasts about 16 weeks and includes a screening period, two treatment periods (with a minimum of 7 days washout period between the treatment periods), and a safety follow-up visit.

The goal of this clinical trial is to determine whether a personalised blood clot prevention plan is more effective than standard treatment in adults with peripheral artery disease (PAD) who have undergone a procedure to restore blood flow to their legs. The main questions it aims to answer are: - Does the personalized plan lower the rate of blood clots in the treated leg one year after the procedure? - Does the personalized plan lower rates of amputation, repeat procedures, bleeding, and death compared to standard treatment? Researchers will compare the personalized TARGET plan which uses a blood test to tailor each person's blood clot prevention medication to the standard treatment to see if the personalized approach works better. Participants will: - Be randomly assigned to either the personalized TARGET plan or standard treatment after their procedure - Have blood tests at 1 week and at 1, 3, 6, 9, and 12 months after their procedure - Have medications adjusted based on blood test results if assigned to the TARGET group

Diabetic Retinopathy (DR) is a common eye condition caused by diabetes, where high blood sugar levels damage the blood vessels in the back part of the eye (called the retina). Over time, this damage can lead to vision problems and even blindness if not treated. This study will assess surabgene lomparvovec (sura-vec) as a potential one-time gene therapy administered in the suprachoroidal space (SCS) for the treatment of diabetic retinopathy (DR) and prevention of vision-threatening events (VTEs) in participants with non-proliferative DR (NPDR) without center-involved diabetic macular edema (CI-DME). This study will consist of 3 portions: a Phase 2b portion, a Phase 3 portion, and a bilateral treatment portion. Approximately 576 adult participants will be enrolled in the study across multiple sites in the United States and Puerto Rico. In the Phase 2b and Phase 3 portions, participants will be randomized to different groups to receive sura-vec and prophylactic steroids or sham and artificial tears in their study eye. If assigned to sham, participants will be given an opportunity to cross over and receive treatment with sura-vec. In the bilateral treatment portion, participants will be enrolled to receive sura-vec and prophylactic steroids in both eyes. In all 3 portions, follow-up in the study will continue through 5 years following administration of sura-vec in each eye. There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study at a clinic. The effect of the treatment will be checked by medical assessments, blood tests, checking for side effects and completing questionnaires.

We are doing the research to see if a CT scan without the dye can help find pulmonary emboli. If you agree to join the study, you will be asked to sign this consent form before we do any research procedures. If you join the research, we will ask you to blow into a small device known as a spirometer to train you to hold your breath after you inhale and exhale. Spirometer is a small handheld device to find out how well your lungs work when you inhale and exhale. For this research, we will obtain two extra sets of CT images at very low levels of radiation dose. The two extra sets of images will take less than 1 minute. Your total participation time is about 5 minutes. We will also review your medical record for up to 30 to 90 days after your CT scan. The main risks of being in the study are exposure to ionizing radiation which may have health risks, and minor inconvenience from the spirometer test. You will not benefit from taking part in this research study. If you take part in this study, your participation may help people in the future. If you decide not to be in the study, you will still have the standard-of-care chest CT with the dye ordered by your doctor. You will not be paid for taking part in this research study.
