Filter by:The design of the present study will be a multicenter prospective observational protocol. Approximately 100 patients will be recruited over the 24-month period with Acute Brain Injury (trauma brain injury, intracerebral hemorrhage, subarachnoid hemorrhage, ischemic stroke), who in their acute phase of intensive care unit require placement of a catheter capable of monitoring intracranial pressure (intra parenchymal catheter or external ventricular shunt). In addition to all the intensive care provided by the most recent guidelines, patients will undergo measurement of optic nerve sheath diameter through ultrasonography. At least, three measurements will be performed within the first 3 hours after admission, within the first 24-48 hours, and at each invasive intracranial pressure value greater than 18 cmH2O. Those patients with intracranial pressure values greater than 35 mmHg. At the first intracranial pressure measurement, patients with eyeball disease or trauma will be excluded. Measurements will be performed following the CLOSED bundle. Analysis of the results will include correlation between the invasive pressure values and the mean value of optic nerve sheath diameter measurements in the two projections (sagittal and transverse). In addition, the correlation of the absolute value of invasive pressure detected with the ratio of the optic nerve sheath diameter measurement to the eyeball diameter measured always ultrasound will be sought.
In this multicenter, randomized, placebo-controlled trial in pre-heat failure patients with hypertension and without diabetes, we will enroll 120 eligible patients to randomized to receive placebo or engagliflozin (10mg/d) for follow them for 6 months. The primary endpoint is the left atrial volume index, which reflects left ventricular diastolic function. We sought to comprehensively evaluate the effect of engagliflozin on the structure and function and explore its underlying mechanisms.
Lower attainment of cardiovascular health (CVH), indicated by the American Heart Association's Life's Simple 7 (LS7; physical activity, diet, cholesterol, blood pressure, body mass index, smoking, glycemia) and Life's Essential 8 (LE8; LS7+sleep) metrics, is a major contributor to Black men having the shortest life-expectancy of any non-indigenous race/sex group. Unfortunately, a paucity of literature exists on interventions aimed at improving CVH among Black men. The team of clinician scientists and community partners co-developed a community-based lifestyle intervention titled Black Impact: a 24-week intervention for Black men with less-than-ideal CVH (<4 LS7 metrics in the ideal range) with 45 minutes of weekly physical activity, 45 minutes of weekly health education, and engagement with a health coach, group fitness trainer, and community health worker. Single-arm pilot testing of the intervention (n=74) revealed high feasibility, acceptability, and retention and a 0.93 (95% confidence interval: 0.40, 1.46, p<0.001) point increase in LS7 score at 24 weeks. Secondary outcomes included improvements in psychosocial stress (i.e., perceived stress, depressive symptoms), patient activation, and social needs. Thus, robustly powered clinical trials are needed to determine the efficacy of Black Impact and to evaluate the underlying interpersonal and molecular pathways by which Black Impact improves psychosocial stress and CVH. Thus, the investigators propose a randomized, wait-list controlled trial of Black Impact. This novel, community-based intervention to provide a scalable model to improve CVH and psychosocial stress at the population level and evaluate the biological underpinnings by which the intervention mitigates cardiovascular disease risk. The proposed study aligns with American Heart Association's commitment to addressing CVH equity through innovative, multi-modal solutions.
The aim of this study is to evaluate the impact of personalized postpartum follow-up cards on completion of postpartum health related tasks. The intervention will consist of a card given to patients at time of discharge. One side of the card will list the patient's name and a list of recommended postpartum follow-up appointments based on their diagnoses at the time of discharge. Participants will be randomized to this intervention or the control group, which will consist of standard education routinely given at discharge. The primary endpoint will be the rate of completion of a postpartum blood pressure check or two hour glucose tolerance test, or both, depending on the patient's discharge diagnosis within the first year after discharge. The secondary endpoints will include establishing care with a primary care provider within the first year after delivery, or completion of postpartum pap smear or colposcopy, as indicated.
There is a need to re-evaluate the patients classified as NCPH and determine whether the new histological classification proposed by the VALDIG applies to the Indian scenario. We intend to identify the patient cohorts who have been diagnosed as NCPH, NCPF, EHPVO, hepatic venous outlet tract obstruction (HVOTO), Veno-occlusive disease (VOD) and sinusoidal obstruction syndrome (SOS) based on their liver biopsy, endoscopy, HVPG, and radiology reports. These patients will be screened to find the patients who fit the diagnosis of PSVD. It is important to establish whether the new definition of PSVD is relevant to the Indian population and establish the usefulness of invasive tests like liver biopsy in diagnosing the disease. The patient cohorts meeting diagnosis of INCPH will be compared with those meeting the new diagnosis of PSVD. The investigators will describe the clinical (demographic, clinical risk factors, socioeconomic status), etiological (associated conditions, coagulation disorders medication use, genetic risk factors), imaging (based on ultrasound Doppler imaging or cross- sectional imaging), endoscopic, fibrosis tests (using non-invasive tests), and the histopathology of the patients who fulfil the criteria of PSVD.
This is a Phase 2, single-center, randomized placebo controlled trial of valsartan (an angiotensin receptor blocker) in adults with pulmonary arterial hypertension. The study will evaluate the safety and clinical efficacy of a 24-week course of valsartan.
The goal of this study is to evaluate the use of aspirin for the prevention of preeclampsia among moderate -to- high-risk pregnant women in tertiary care hospitals in Nigeria followed by a qualitative study to evaluate the barriers and facilitators of aspirin use in prenatal care for the prevention of preeclampsia in Nigeria. The main question[s] it aims to answer are: 1. Is Aspirin used for the prevention of preeclampsia among pregnant women in Nigeria? 2. What factors promote or prevent the utilization of Aspirin for preeclampsia prevention among pregnant women in Nigeria.
The purpose of this study is to evaluate the efficacy and safety of AD-223
This early feasibility study is intended to characterize the impact of pulmonary artery denervation on the quality of life in Heart Failure Patients with Group 2 Pulmonary Hypertension
Pulmonary hypertension (PH) is a pathophysiological disorder that may involve multiple clinical conditions and may be associated with a variety of cardiovascular and respiratory diseases. The complexity of managing PH requires a multidisciplinary approach, with active involvement of patients with PH in partnership with clinicians.(1) All age groups are affected. Present estimates suggest a PH prevalence of 1% of the global population. Due to the presence of cardiac and pulmonary causes of PH, prevalence is higher in individuals aged 65 years. Globally, LHD is the leading cause of PH. Lung disease, especially chronic obstructive pulmonary disease (COPD), is the second most common cause. In the UK, the observed PH prevalence has doubled in the last 10 years and is currently 125 cases/million inhabitants. (2) Pulmonary hypertension is defined by a mean pulmonary arterial pressure (mPAP) more than 20 mmHg at rest according to the 2022 ESC/ERS Guidelines for the diagnosis and treatment of pulmonary hypertension . It is essential to include PVR and pulmonary arterial wedge pressure (PAWP) in the definition of pre-capillary PH, in order to discriminate elevated PAP due to pulmonary vascular disease (PVD) from that due to left heart disease (LHD), elevated pulmonary blood flow, or increased intrathoracic pressure.(3) Clinical classification of pulmonary hypertension includes GROUP 1 Pulmonary arterial hypertension (PAH), GROUP 2 PH associated with left heart disease, GROUP 3 PH associated with lung diseases and/or hypoxia, GROUP 4 PH associated with pulmonary artery obstructions and GROUP 5 PH with unclear and/or multifactorial mechanisms. (3) Pulmonary hypertension is frequently observed in patients with COPD and/or emphysema, diffuse parenchymal lung diseases and hypoventilation syndromes. Pulmonary hypertension is uncommon in obstructive sleep apnoea unless other conditions coexist, such as COPD or daytime hypoventilation. In patients with lung disease, PH is categorized as non-severe or severe, Whereas non-severe PH is common in advanced COPD and ILD defined by spirometric criteria, severe PH is uncommon, occurring in 1-5% of cases of COPD and ,10% of patients with advanced ILD, with limited data in obesity hypoventilation syndrome.(4) Pulmonary hypertension presenting in patients with lung disease may be due to a number of causes, including undiagnosed CTEPH or PAH. A number of distinct phenotypes of PH in patients with lung disease, including a pulmonary vascular phenotype, have been proposed. The pulmonary vascular phenotype is characterized by better preserved spirometry, low DLCO, hypoxaemia, a range of parenchymal involvement on lung imaging, and a circulatory limitation to exercise.(5) Cardiac comorbidities are also common in patients with lung disease and may contribute to increased risk for hospitalization, longer length of stay, pulmonary hypertension and CVD-related mortality.(6) A vast category of patients suffering from parenchymal lung diseases (often accompanied by minor pulmonary impairment on pulmonary function test and/or CT scan) with an unexplained severe degree of PH was brought to the attention of physicians. In these patients, the development of moderate to severe PH, which is disproportionate to the degree of parenchymal lung disease and hypoxia, has been termed "out-of-proportion" PH, and an arbitrary value of . 35 mm Hg mean pulmonary artery pressure has been selected to identify this category of patients.(7) and there is limited data about the Out-of proportion PH and it different phenotypes
