The American Society of Clinical Oncology (ASCO) Survey on Coronavirus 2019 (COVID-19) in Oncology Registry (ASCO Registry) aims to help the cancer community learn more about the patterns of symptoms and severity of COVID-19 among patients with cancer, as well as how COVID-19 is impacting the delivery of cancer care and patient outcomes. The ASCO Registry collects both baseline and follow-up data on how the virus impacts cancer care and cancer patient outcomes during the COVID-19 pandemic.
4,972 patients who underwent surgery for primary CRC between January 2004 and December 2015 at Seoul National University Hospital were retrospectively reviewed. CA19-9 is a valuable prognostic and diagnostic marker for CRC when used adjunctively with CEA and can be a supplementary marker with CEA to improve sensitivity, especially with elevated preoperative CA19-9.
About 2 billion people worldwide are infected with tuberculosis (TB). Ninety percent of those people have latent TB infection (LTBI). Risk factors like malnutrition, diabetes mellitus (DM), and helminth infection can affect the development of active TB. Researchers want to study LTBI individuals with these issues to see how they may contribute to a person s higher risk for developing active TB. This study will take place in Chennai, India. Objective: To estimate the prevalence of malnutrition, DM, and helminth infections in people with LTBI. Eligibility: People age 14 65 with or without LTBI. Design: Participants will be screened with a medical history and physical exam focused on symptoms of active TB. Those who have TB symptoms will not take part in the study. Those who do not have TB symptoms will have a physical exam with vital signs, height, and weight. They will give blood and stool samples. Participants will be assigned to 1 of 6 groups. They will repeat some of the screening tests. They will give urine samples. Some groups will have a chest X-ray. Some groups will have an ultrasound of the abdomen. Participants will complete a survey about their history of smoking and drug and alcohol use. Participants will have data collected about their nutritional status and body composition. Their skinfold thickness, ratio of waist/hip circumference, and grip strength will be measured. Participants with DM, malnutrition, or helminth infection will be given standard of care or referred for follow-up treatment. Participation will last up to 6 months. ...
This clinical trial examines a group-mediated cognitive behavioral resistance exercise intervention in head and neck cancer patients who are undergoing chemoradiation treatment. Chemoradiation is the established standard of care for locally advanced head and neck cancer patients. However, many head and neck cancer patients experience clinically meaningful declines in muscle mass, physical function, and quality of life during and following treatment. Resistance exercise has been shown to improve muscle mass, body composition, and physical function when integrated with appropriate standard of care nutritional counseling/supplementation. This trial may help researchers determine the important of integrating exercise interventions with routine cancer care.
This main long-term extension study is designed to evaluate the long-term safety and tolerability of faricimab 6 milligrams (mg) administered by intravitreal injection at a personalized treatment interval (PTI) to participants with neovascular age-related macular degeneration (nAMD) who enrolled in and completed one of the Phase III studies: GR40306 (NCT03823287) or GR40844 (NCT03823300), also referred to as the parent studies. Eligible patients who consent to participate in this main study will be enrolled upon completion of the end-of-study visit in the parent study. Additionally, there is a substudy that is being conducted. The aim of this substudy is to evaluate the impact of intravitreal faricimab on the health of the corneal endothelial cells in the study eyes of patients with nAMD to fulfill a U.S. Food and Drug Administration (FDA) post-marketing requirement. The fellow eyes of the same enrolled participants in the substudy will serve as the controls.
Background of the study: Cataract is widely prevalent in especially elderly and cataract extraction surgery has thus become one of the most performedsurgeries worldwide. In recent decades the safety of cataract surgery has greatly improved and it is considered one of the safestsurgeries to be performed. Postoperative management consists of routine examinations within one week, to ascertain no adverseevents have occurred immediately after surgery, and between 4-6 weeks, to determine the refractive error. The incidence of seriousadverse events following cataract surgery is estimated to be 1%. As a result, the majority of patient visits after cataract surgery willbe uneventful. Nonetheless valuable time and hospital resources are consumed. Remote monitoring could replace clinicalexaminations in selected patient groups. However, this practice of digital remote monitoring which the patient can use independentlyhas not been clinically validated yet. Objective of the study: To determine non-inferiority of the corrected distance visual acuity (CDVA) with the prescription obtained through the web-basedmeasurement of refractive error, compared to usual care, in patients who underwent routine cataract surgery. Study design: Observational randomized trial without interventions Study population: Patients eligible for cataract surgery, without visual acuity influencing comorbidities or predisposing complicating factors. Primary study parameters/outcome of the study: costeffectiveness Secundary study parameters/outcome of the study (if applicable): Corrected distance visual acuity at the final post-operative visit, uncorrected distance visual acuity, refractive error(sphere/cylinder/axes), patient reported outcome measurements, adverse events.
The CARE-HK in HF is a registry study based on the hypothesis that adherence to guidelines is associated with improved real-world outcomes for heart failure (HF) patients. For the purpose of this study, adherence to guidelines is defined as adherence to RAASi treatment recommendations, according to the AHA/ACC and ESC guidelines. Objectives relating to patiromer effectiveness will only be evaluated if a sufficient number of patients are available. The study aims to evaluate in patients at high risk of hyperkalaemia; patients treated with ACEi/ARB/ARNi, and either treated with or candidates for treatment with MRA.
This is a study to determine how a virtual model for the management of lung nodules compares to a face-to-face clinic for patient satisfaction, quality of life and cost.
Epilepsy is a common neurological disease, manifested in the sudden abnormal discharge of neurons leading to short-term brain dysfunction, has become the neurology after headache the second most common disease. In China, the prevalence of epilepsy is about 4.7-8.5 per 1,000, and more than 400,000 new cases of epilepsy are developed each year. Of these, 30% of patients were treated with ineffective medication, developing into a drug-incurable epilepsy that required surgery and other treatments. The most common type of epilepsy is temporal lobe epilepsy, while the common complication in temporal lobe epilepsy is hippocampal sclerosis, which often requires surgical removal. The incidence of inner temporal lobe epilepsy associated with hippocampal sclerosis is increasing, but its exact cause and specific pathogenesis are still unclear, so clarifying its pathogenesis will contribute to the understanding of temporal lobe epilepsy and the improvement of surgical procedures. This study is intended to get single-cell transcriptome as well as spatial transcriptome data of temporal lobe and hippocampus samples. By studying gene expression change associated with epilepsy and hippocampus sclerosis, we intended to find possible prognostic-related molecules and to deepen understanding of pathological changes in epilepsy at the molecular level.
The DCB-ACS trial is a prospective, multi-center, non-inferiority, randomized controlled trail. The purpose of this trial is to evaluate the safety and efficacy of drug-coated balloon(DCB) in de novo lesions for acute coronary syndromes (ACS) .
