Coronary Artery DiseaseMenopause

Chronic coronary syndrome (CCS) is the leading cause of death in women in the most developed regions of Brazil. The primary etiopathogenic mechanism is the process of atherosclerosis. A healthy diet rich in fruits and vegetables is associated with a lower incidence of CCS. The higher consumption of these foods promotes greater availability of phenolic compounds, and the higher intake of these compounds is one of the main hypotheses for vascular health. Quercetin, a phenolic compound, is the most abundant natural antioxidant belonging to the group of flavonoids. Quercetin improves lipoprotein metabolism, has an antioxidant capacity, produces vasodilating substances in the vascular endothelium, and reduces platelet aggregability. Likewise, statins are medications known to reduce cardiovascular events in women with CCS by reducing serum LDL-cholesterol levels and, to a lesser extent, by possible pleiotropic effects. In turn, SIRT1 is one of the 7 classes of proteins. It mediates various metabolic pathways in response to nutritional stimuli, particularly for caloric restriction and phenolic compounds, as well as coordinating the production and secretion of important hormones. However, the impact of quercetin supplementation and statin administration on serum endogenous estrogen levels is unknown

Clinical Observation of CABA System in the Treatment of End-stage Liver Disease With Inflammation...

To Evaluate the Clinical Efficacy and Safety of the New ALSS

End-stage liver disease (ESLD) refers to the late stage of liver disease caused by various chronic liver damage. ESLD is an important cause of global incidence rate and mortality, which has a significant impact on the health care system. ESLD is associated with various types of immune dysfunction. The artificial liver support system (ALSS) is an extracorporeal support system that temporarily and partially replaces the partial function of the liver. Its treatment mechanism is to remove all kinds of harmful substances, supplement essential substances, improve the internal environment, create conditions for hepatocyte regeneration and liver function recovery, or use it as a symptomatic support treatment method during the perioperative period of liver transplantation. In this study, we plan to use BS330 for plasma bilirubin adsorption. On this basis, we will add a CA280 cytokine adsorption column to establish a new artificial liver combination model CABA for the immune inflammatory damage mechanism of liver failure.

Keck Medicine of University of Southern California Thrive Study

Burnout

Burnout and job dissatisfaction among clinicians are one of the greatest challenges facing healthcare today. Clinicians report feeling less engaged in their work and are leaving their fields in large numbers which reflects increasing stress from the pandemic coupled with increased administrative and regulatory demands and a decreased sense of autonomy. To attenuate these factors the current study will enact a series of interventions that would decrease mental distress, increase self-efficacy, and attenuate inefficiencies in their work environment to achieve sustainable improvement. The investigators will offer psychological training using techniques that have been shown to impact individual's mental health that target feelings of demoralization, depression and anxiety that result from chronic stress. Additionally, the investigators will offer individualized training on optimization of the Electronic Health Record (EHR) to help clinicians from different fields and settings reduce their time and effort needed for documentation. The investigators will also engage clinicians in systemic redesign to empower clinician-directed changes to the health system environment. The investigators anticipate that each intervention will positively affect emotional wellbeing, skills mastery of the Electronic Health Record (EHR), and environmental dissatisfaction to reduce overall burnout.

Short Versus Long-term Androgen Deprivation Therapy With Salvage Radiotherapy in Prostate Cancer....

Prostate CancerSalvage Radiotherapy3 more

The optimal indication for ADT has long been a point of controversy, at least until the results of randomised trials comparing RT with and without ADT were published. NCCN guidelines and most retrospective series and left the decision to prescribe ADT in combination with RT to the discretion of the treating physician, despite a lack of clear scientific evidence to support this recommendation. The percentage of patients in those retrospective series who received hormone therapy ranged from 33% to 71%, but generally involved patients with adverse prognostic factors (Gleason score > 7, stage pT3-T4, PSA > 1 ng/mL in cases with biochemical recurrence [BCR], and PSA doubling time [PSA-DT] < 6 months). Despite the heterogeneity in those studies in terms of treatment duration, RT dose, and treatment volumes, most of the studies found that ADT significantly prolonged biochemical relapse-free survival (BRFS), especially in patients with PSA levels > 1 ng/mL at recurrence. The results of two randomised trials evaluating SRT with or without ADT were published in 2017, with both trials demonstrating a benefit for ADT in this clinical setting. A follow-up study confirmed the value of ADT in combination with SRT in terms of better PFS and, in the RTOG study, an improvement in overall survival (OS). Despite the lack of data from phase III trials regarding the influence of PSA-DT, the BRFS interval, and the Gleason score in terms of their effects on the clinical course of patients who develop BCR, there is strong evidence from other studies to support the use of these variables (together with age and comorbidities). Given the available evidence, we believe that these variables should be considered when determining the indications for ADT. In line with the philosophy underlying the approach used by D'Amico to develop a risk classification system for prostate cancer patients at diagnosis, we propose three risk groups. According to Pollack et al. and Spratt et al., low-risk patients would not benefit from hormone therapy, especially long-term ADT, due to the deleterious effects of such treatment. By contrast, intermediate and high risk patients would be candidates for ADT combined with RT. However, the optimal duration of ADT in these patients (6 months vs. 2 years) remains undefined and needs to be determined prospectively in a randomised trial, similar to the approach used in the DART 05.01 trial. SRT and ADT are widely used in routine clinical practice to treat patients who develop BCR after prostatectomy. In this context, we intend to perform a multicentre, phase III trial to define the optimal duration of ADT (6 vs. 24 months).

Normal Saline Versus Lactated Ringer's Solution for Acute Pancreatitis Resuscitation

Acute Pancreatitis

Background: Acute pancreatitis (AP) is an acute inflammatory disease of variable severity. Mild cases have an uncomplicated clinical course, but local and systemic complications occur in one-third of patients and are associated with a longer hospital stay, increased morbidity, increased hospital costs, and increased risk of death. Some evidence suggests that fluid resuscitation with lactated Ringer's solution (LR) may have an anti-inflammatory effect on AP when compared to normal saline (NS), and may be associated with a decrease in severity, but randomized controlled trials showed conflicting results. The WATERLAND trial has been designed to investigate the efficacy and safety of fluid resuscitation using LR as compared with NS in patients with AP. Methods: The WATERLAND trial is an international multicenter, open-label, parallel-group, randomized, controlled, superiority trial. Patients will be randomly assigned in a 1:1 ratio to receive LR versus NS-based moderate fluid resuscitation. The primary outcome will be moderately severe to severe AP, according to the revision of the Atlanta classification. The primary safety outcome will be a composite variable involving any of the following: fluid overload, acute kidney injury, hyperkalemia, hypercalcemia, or acidosis. A total sample of 720 patients, 360 in the LR group and 360 in the NS group will achieve 90% power to detect a difference between the group proportions of 10%, assuming that the frequency of moderately severe to severe AP in LR group will be 17%. The frequency in the NS group is assumed to be 27% under the null hypothesis and 17% under the alternative hypothesis. The test statistic used is the two-sided Z test with pooled variance set at a 0.05 significance level.

Short Course Radiotherapy for the Treatment of Patients With Glioblastoma, SAGA Study

Glioblastoma

This phase II trial compares the effect of short course radiotherapy (RT) to standard course RT for the treatment of patients diagnosed with glioblastoma (GBM). The researchers want to learn whether the shorter course treatment is non-inferior (not worse than the standard of care), for patients with GBM. Radiation therapy uses high energy x-rays, particles, or radioactive seeds to kill cancer cells and shrink tumors. Short course radiotherapy delivers higher doses of radiation over a shorter period of time and may kill more tumor cells and have fewer side effects.
