The diagnosis of cancer can be a major trigger for new sleep problems, especially insomnia, in people who did not have sleep issues before. Insomnia may appear early in the care pathway and can continue over time, often interacting with other physical or emotional symptoms. The main goal of this preliminary study is to describe how insomnia develops during the first months after a cancer diagnosis in patients who had no sleep problems at the time of diagnosis. This will be done through regular follow-up over time. A secondary aim is to identify the factors that may contribute to the onset or persistence of insomnia, such as the cancer treatments patients receive, as well as any medical or non-medical therapies used to manage sleep difficulties. The study will also look at whether patients who develop sleep problems are referred to psychologists trained in specific therapies for insomnia, and how well they follow and adhere to these treatments.
Background: Most drugs that treat mood disorders take a long time to work. Ketamine works within hours. A dose can last for a week or more. Certain receptors in the brain might help ketamine work. A drug that blocks these receptors might affect how it works. Objective: To see if the antidepressant response of ketamine is linked to AMPA receptors. Eligibility: Adults ages 18-70 with major depression disorder without psychotic features Design: Participants will be screened under protocol 01-M-0254. They will have blood tests and a physical exam. Participants will stay at the NIH Clinical Center for 5 weeks. Phase 1 lasts 4 weeks. For 2 weeks, participants will taper off their psychiatric medicine. Then they will have the following tests: * Blood draws * Psychological tests * MRI: Participants will lie in a machine that takes pictures of their brain. * MEG: Participants will lie down and do tasks. A cone lowered on their head will record brain activity. * Optional sleep tests: Electrodes on the scalp and body and belts around the body will monitor participants while they sleep. * Optional TMS: Participants will do tasks while a wire coil is held on their scalp. An electrical current will pass through the coil that affects brain activity. For phase 2, on day 0 participants will take the study drug or a placebo orally. While having a MEG, they will get ketamine infused into a vein in one arm while blood is drawn from a vein in the other arm. On day 1, participants will again take the study drug or a placebo orally. On days 3-7, they will repeat many of the phase 1 tests. Days 8 and 9 are optional and include an open label ketamine treatment and many of the phase 1 tests.
This pilot randomized controlled trial will evaluate the feasibility and preliminary effects of a six-week behavioral intervention designed to improve mood and daily functioning in adults who have experienced a stroke and report depressive symptoms and difficulty becoming engaged in activities after waking. Participants will be randomly assigned to either the behavioral intervention or a health education program. Assessments will be completed before and immediately after the six-week program and will include questionnaires and seven-day monitoring of sleep, activity, and mood. The study will also examine feasibility indices such as participant retention, intervention attendance, acceptability, and preliminary changes in mood.
The purpose of this study is to assess the efficacy and safety of the study drug, levosimendan (given orally), compared to placebo in participants with pulmonary hypertension with heart failure with preserved left ventricular ejection fraction (PH-HFpEF) as measured by the change in 6-Minute Walk Distance.
If pulmonary hypertension is suspected, a right heart catheterization is usually performed to confirm or rule out the diagnosis. As part of this examination, blood samples are taken from various locations as standard and blood gas analyses are performed. One of the most important measurements during the right heart catheterization is the measurement of the pulmonary arterial occlusion pressure by the so-called wedge maneuver. To measure this value, the catheter with inflated balloon must be advanced into the pulmonary vessels until the "wedge" position is reached, i.e. the balloon completely occludes a branch of the pulmonary artery. In this study, the investigators want to characterize patients with pulmonary hypertension of different causes in more detail. To do that, two blood samples (totaling approximately 4 mL of blood, one sample directly after occlusion and the other one two minutes later) will be drawn during the right heart catheterization from the above-mentioned "wedge" position", behind the inflated balloon, and blood gas analyses will be performed on these samples. In addition, various clinical parameters (comorbidities, etc.) will be recorded by means of clinical questionnaires. Follow-up data will be analyzed and correlations with the aforementioned blood gas analyses will be examined. The results of the study will be used to more precisely characterize the still vague concept of secondary pulmonary hypertension. This could help to develop new therapeutic strategies in some subgroups in the future.
The purpose of this study is to determine whether Apixaban is effective and safe in the treatment of portal vein thrombosis Occurring more than one year after laparoscopic splenectomy and azygoportal disconnection.

The purpose of the study is to evaluate the efficacy, transorbital alternating current stimulation (rtACS) using the EYETRONIC for the treatment in patients with glaucoma.
The HAMA bank is an initiative aimed at collecting, preparing, and storing biological samples from patients treated for malignant hypertension and included in the HAMA cohort. Conducted under CRB (ISO20387) conditions, this biobank serves as an essential resource for understanding the disease's pathophysiology, as well as for identifying novel biomarkers and therapeutic targets
DSLT demonstrates a ≥ 20% reduction of IOP from pre-treatment baseline in POAG patients naïve of previous glaucoma treatment at 12 months.
Hypertension is the most frequent chronic pathology in France and in the world. It is one of the main modifiable cardiovascular risk factors. In France, 50% of treated hypertensives are uncontrolled and only 30% of treated patients are fully adherent to their antihypertensive treatment. Poor adherence to drug treatments is considered as one of the main causes of non-control of hypertension. Since 2018, a new profession has entered the French healthcare system: Advanced Practice Nurses (APN). They have many broad skills, at the interface of nursing and medical exercises. The purpose of this interventional study is to assess the impact of APN on blood pressure (BP) control in the context of usual care of hypertension thanks to a better adhesion of patients and a better therapeutic alliance. The hypothesis formulated is that an individual APN intervention, included in a usual hypertension management, improves BP control.
Objective of this registry is to collect a representative set of real world data on the use of Dilapan-S® for pre-induction cervical ripening in daily clinical practice. Upon completion of the registry, relevant collected data will be analyzed and published.
Pulmonary arterial hypertension (PAH) is a rare and serious condition that affects the blood vessels of the lungs and can significantly limit daily activities and quality of life. Some patients with PAH use inhaled iloprost, a medication that requires several inhalations per day, which can be difficult to maintain over time. Oral selexipag is an alternative treatment that may reduce treatment burden and improve adherence. The PROMISE study aims to evaluate how switching from inhaled iloprost to oral selexipag affects patients' quality of life, satisfaction with treatment, and adherence in real-world clinical practice. Patient-reported outcome questionnaires will be used to understand patients' perceptions of symptoms, daily functioning, and overall improvement after the transition. Adult patients with PAH who are receiving inhaled iloprost and whose physicians decide to switch treatment to oral selexipag will be followed over time. A comparison group of patients who continue using inhaled iloprost will also be observed. The study does not involve any experimental treatment or changes to routine clinical care. All medications are prescribed as part of standard medical practice. The results of this study may help improve understanding of the patient experience during treatment transitions in PAH and support more patient-centered treatment decisions.
The Polypill Approach for Multiple Cardiovascular Risk Factors (PACIF) trial is a multicenter randomized controlled trial that will test the effectiveness and safety of a fixed-dose combination strategy for integrated management of hypertension, dyslipidemia, and diabetes among adults aged 50 to 75 years in China. The trial will evaluate whether a simplified regimen combining blood pressure-lowering, lipid-lowering, and glucose-lowering therapy improves the 10-year cardiovascular disease risk score at phase 1. Participants will be followed to determine whether the fixed-dose combination strategy reduces major cardiovascular events and cognitive function compared with usual care at phase 2.
Schistosomiasis-associated pulmonary arterial hypertension is a serious condition that can lead to shortness of breath, heart failure, frequent hospitalizations, and early death. Although treatments for pulmonary arterial hypertension have improved over time, patients with this specific cause of the disease are often not included in long-term studies. Selexipag is an oral medication used to treat pulmonary arterial hypertension and is part of routine clinical care in Brazil. Its long-term effects in patients with schistosomiasis-associated pulmonary arterial hypertension are not well understood. The PROPULSE-Sch study aims to evaluate long-term clinical outcomes in patients with schistosomiasis-associated pulmonary arterial hypertension who received selexipag, compared with similar patients who did not receive this medication before it became available at the study center. This is an observational study using data from routine medical care. All treatments are prescribed by the treating physicians, and participation in the study does not change patient care. The results may help improve understanding of long-term outcomes and support treatment decisions in this population.
This study evaluates whether a personalized mobile reminder program improves treatment adherence and clinical outcomes in adults with primary open-angle glaucoma (POAG) using topical antiglaucoma eye drops. Poor adherence to long-term eye-drop therapy is common in glaucoma care and may contribute to inadequate intraocular pressure (IOP) control and disease progression. Participants are randomized to either (1) a digital adherence intervention or (2) standard outpatient follow-up. The intervention consists of daily interactive SMS/WhatsApp medication reminders plus weekly brief educational messages for 3 months. The primary outcome is change in medication adherence measured by the Morisky Medication Adherence Scale-8 (MMAS-8) at month 3. Secondary outcomes include change in IOP, eye-drop instillation technique, and treatment satisfaction. Exploratory analyses assess the relationship between adherence level and OCT-based retinal nerve fiber layer (RNFL) progression metrics. The goal is to determine whether a low-cost, scalable mobile strategy can improve short-term glaucoma management in routine practice.
The pharmacological treatment strategy is then tailored to the underlying hemodynamic phenotype of each patient. That is, rather than applying a one-size-fits-all treatment for all patients, therapy is tailored to the specific characteristics of how the cardiovascular system functions in each patient (e.g., whether the problem is more related to blood volume, vascular resistance, cardiac output, etc.). The goal is to personalize therapy to more effectively treat hypertensive states of pregnancy.
Pulmonary hypertension represents a challenging and heterogeneous condition that is associated with high mortality and morbidity if left untreated. Artificial intelligence is used to study and develop theories and methods that simulate and extend human intelligence, which is being applied in fields related to cardiovascular diseases. The study intends to combine multimodal clinical data of patients who undergo right heart catheterization at Fuwai Hospital with artificial intelligence techniques to create programs that can screen and diagnose pulmonary hypertension.
The purpose of this intervention is to help new mothers who had elevated blood pressure during pregnancy become more physically active after birth. The investigators will connect data from FitBits to the electronic health record. Women will then get weekly messages with feedback and goals to help them stay active. The investigators will test if the intervention improves step counts and blood pressure after pregnancy. The investigators will also test if the intervention is feasible and enjoyed by postpartum women.
24 hour ambulatory blood pressure (ABP) monitoring should be the first choice for diagnosis and treatment of hypertension according to European Societyof Hypertension (ESH) and the European Society of Cardiology (ESC) guideline on ambulatory blood pressure monitoring. Finally, we should promote the clinical application of 24 hour ambulatory blood pressure monitoring to greatly improve the management level of hypertension in China and effectively reduce the risk caused by hypertension in the population. Information of hypertensive patients with ambulatory blood pressure monitoring was prospectively registered nationwide,and then to investigate whether there was difference in cardiovascular prognosis according to the control of ABP.
