Improvement is measured by a composite endpoint, namely, the "Score of PACS progression reversal"
The goal of this observational study is to know the prevalence of PCOS among economically productive and reproductive age women from Medellín and the Valle de Aburrá, Colombia. The main questions it aims to answer are: 1. What is the phenotypic distribution of PCOS detected in women seeking medical attention as a requirement for employment in Medellín and the Valle de Aburrá, Colombia? 2. What is the effect of environmental factors, such as geographical location and diet, and biological factors (such as obesity and ethnicity/race) on the prevalence and phenotype of PCOS in this populatión? Participants will undergo anthropometric measurements and physical examination for hirsutism, acne, alopecia, acanthosis nigricans, and thyroid enlargement. During the initial visit, a transvaginal or transabdominal pelvic ultrasonography will be performed. A sample of venous blood will be collected in plain tubes for serum cryopreservation and for immediate glucose estimation. Some participants will be rescheduled for a second evaluation visit for additional assessment when they have a possible PCOs.
Many patients with postural orthostatic tachycardia syndrome (POTS) have decreased plasma volume. Current POTS guidelines recommend ~10 g of salt and 2-3 L of fluid per day. Despite this recommendation, there is no long term data evaluating the use of salt in POTS. This randomized, placebo-controlled cross-over trial will evaluate a high salt diet, compared to a normal salt diet over a period of 3 months. Participants will complete 3 in lab evaluations including autonomic function testing, tilt table testing, blood volume and urine sodium evaluation, plasma catecholamine measurements and and cytokine measurements.
PFPS, also known as patellofemoral pain syndrome, is a prevalent musculoskeletal condition that primarily affects adolescents and young adults. When engaging in various activities, such as stair climbing, running, jumping, kneeling, or prolonged sitting, it is characterized by aching pain in the peripatellar region. Any disruption of these would result in abnormal PFJ overloading. Normal patellar tracking on the trochlea groove relies on the coordination and balance of many structures, including soft tissues, muscles, tendons, ligaments, and the shape of articular surfaces around the knee joint. Research in a variety of fields has received support the therapeutic exercise known as "clamshells" for stabilizing the pelvis by strengthening the hip abductors and external rotators.VMO strengthening exercises are also essential in keeping the patella in the trochlear groove and lowering the lateral vector force on the patellofemoral joint. This research aims to evaluate the effects of clamshells exercise and Vastrus medialis oblique strengthening exercise in patients with Patellofemoral pain syndrome. The study would be randomized clinical trial. Total fourty two subjects will be assigned randomly by using lottery method into two groups. Group A will be given clamshell exercise with baseline treatment while Group B will receive targeted vastrus medialis oblique strengthening exercise with baseline treatment. After confirmation of diagnosis with physical examination as well as zohlar's test /20 cm step down test are recommended. Numeric pain rating scale (NPRS) and Lower extremity functional scale (LEFS) would be used as an outcome measure tools for pain and functional limitation respectively. Measurements will be taken at (Baseline and at the end of treatment session). The collected data will be analyzed in Statistical Package for the Social Sciences (SPSS) 25.0. Parametric/non-parametric tests will be applied after testing normality of data.
Myelodysplastic syndromes, primarily affecting older adults, are a heterogeneous group of clonal disorders of hematopoietic stem cells characterized by ineffective hematopoiesis that manifest clinically as anemia, neutropenia, and/or thrombocytopenia of variable severity; these often result in RBC- transfusion dependent (TD) anemia, increased risk of infection, and/or hemorrhage, as well as a potential to progress to acute myeloid leukemia (AML). Lenalidomide is approved for red blood cell transfusion-dependent (RBC TD) anemia due to low-risk myelodysplastic syndromes (MDS) with a chromosome 5q deletion (del5q) with or without additional cytogenetic abnormalities. About one third of patients are refractory/resistant/intolerant and will require further treatment options. Luspatercept (ACE-536), an erythroid maturation agent, is a recombinant fusion protein consisting of a modified form of the extracellular domain (ECD) of the human activin receptor type IIB (ActRIIB) linked to the Fc portion of human immunoglobulin G1 (IgG1-Fc). Luspatercept acts on endogenous inhibitors of late-stage erythropoiesis (eg, growth differentiation factor 11, GDF11) to increase release of mature erythrocytes into circulation. Nonclinical data have demonstrated that luspatercept binds to negative regulators governing late-stage erythroid development to inhibit their action, thereby promoting the maturation of erythrocytes in the bone marrow. Luspatercept is indicated for the treatment of adult patients with transfusion-dependent anaemia associated with beta-thalassaemia and due to very low, low and intermediate-risk MDS with ring sideroblasts, who had an unsatisfactory response to or are ineligible for erythropoietin-based-therapy. It is not indicated for other MDS subtypes. Unfortunately, patients with MDS with del5q refractory/resistant/intolerant to lenalidomide are excluded from clinical trials that evaluate novel treatments for the anemia of RBC TD lower risk MDS. Therefore, treatment of anemia in such patients is an unmet need. QOL-ONE Phoenix is a Phase 2, multicenter, single arm, prospective study. The primary objective of the study is to evaluate the effect of luspatercept on RBC TI in subjects with MDS with del5q with IPSS-R very low, low, or intermediate risk and < 5% bone marrow blasts, resistant/refractory/intolerant to lenalidomide and who require RBC transfusions. The study is divided into a Screening Period, a 2-year Treatment Period and a 3-year Follow-up Period. Primary objective is to evaluate the effect of luspatercept on RBC TI (lack of transfusions for 8 consecutive weeks within the first 24 weeks) in subjects with MDS with del5q with IPSS-R very low, low, or intermediate risk and < 5% bone marrow blasts, resistant/refractory/intolerant to lenalidomide and RBC TD.
Myelodysplastic syndromes (MDS) are clonal diseases of hematopoietic stem cells (HSC) characterized by dysplastic and inefficient hematopoiesis related to excessive progenitor cell death. Ferroptosis is a recently described cell death mechanism and we think that it could be a major player in the pathophysiology of MDS, involved in the cell death that characterizes these diseases and contributing to cytopenias. The study aims to demonstrate that there is a significant activation of this phenomenon in MDS patients compared to a population of subjects without MDS.
This is a A Multicenter, Randomized, Double-blind, Placebo-controlled, Clinical Trial to Evaluate the Efficacy and Safety of Different Doses of OPS-2071 in the Treatment of Irritable Bowel Syndrome of Diarrhea type (IBS-D).The trial is mainly divided into three periods: screening period, treatment period and follow-up period.
Postural tachycardia syndrome (POTS) is the most common chronic cause of postural lightheadedness, and upright confusion afflicting many Americans, mostly young women. Many POTS patients hyperventilate by increasing their depth of breathing that produces tachycardia, alters blood flow and blood pooling in the body and importantly reduces brain blood flow causing "brain fog". In this proposal the investigators will demonstrate in young women that abnormal repeated brief impairment of blood pressure and brain flow just after standing sensitizes the body's oxygen sensor in POTS to respond as if it were in a low oxygen environment causing hyperventilation and its consequences. In this project the investigators will use various drugs that will help to understand the mechanisms that cause POTS in this unique subset of POTS patients who hyperventilate.
The goal of this research study is to test the efficacy of a novel immunosuppressive agent, belumosudil, in allogeneic hematopoietic stem cell transplant (HSCT) recipients who have been newly diagnosed or have developing (early stage) bronchiolitis obliterans syndrome (BOS). The name of the study drugs involved in this study are: - Belumosudil (an immunotherapy) - Fluticasone (an intranasal corticosteroid) - Azithromycin (an antibiotic) - Montelukast (a leukotriene receptor antagonist) - Prednisone (a corticosteroid)
Acute Respiratory Distress Syndrome (ARDS) is often complicated by Right Ventricular Dysfunction (RVD), and the incidence can be as high as 64%. The mechanism includes pulmonary vascular dysfunction and right heart systolic dysfunction. Pulmonary vascular dysfunction includes acute vascular inflammation, pulmonary vascular edema, thrombosis and pulmonary vascular remodeling. Alveolar collapse and over distension can also lead to increased pulmonary vascular resistance, Preventing the development of acute cor pulmonale in patients with acute respiratory distress. ARDS patients with RVD have a worse prognosis and a significantly increased risk of death, which is an independent risk factor for death in ARDS patients. Therefore, implementing a right heart-protective mechanical ventilation strategy may reduce the incidence of RVD. APRV is an inverse mechanical ventilation mode with transient pressure release under continuous positive airway pressure, which can effectively improve oxygenation and reduce ventilator-associated lung injury. However, its effect on right ventricular function is still controversial. Low tidal volume (LTV) is a mechanical ventilation strategy widely used in ARDS patients. Meta-analysis results showed that compared with LTV, APRV improved oxygenation more significantly, reduced the time of mechanical ventilation, and even had a tendency to improve the mortality of ARDS patients However, randomized controlled studies have shown that compared with LTV, APRV improves oxygenation more significantly and also increases the mean airway pressure. Therefore, some scholars speculate that APRV may increase the intrathoracic pressure, pulmonary circulatory resistance, and the risk of right heart dysfunction but this speculation is not supported by clinical research evidence. In addition, APRV may improve right ventricular function by correcting hypoxia and hypercapnia, promoting lung recruitment and reducing pulmonary circulation resistance. Therefore, it is very important to clarify this effect for whether APRV can be safely used and popularized in clinic.we aim to conduct a single-center randomized controlled study to further compare the effects of APRV and LTV on right ventricular function in patients with ARDS, pulmonary circulatory resistance (PVR) right ventricular-pulmonary artery coupling (RV-PA coupling), and pulmonary vascular resistance (PVR).
