Background: Hypertension is a public health problem; the World Health Organization (WHO) estimates that more than 1280 million people suffer it. The treatment of said condition is pharmacological and non-pharmacological. Physical activity is part of the treatment, but unfortunately few adults can be classified as physically active. There is evidence that performing physical exercise reduces systolic blood pressure by up to 5 mm Hg, which has associated with reduced heart disease by up to 9%, ictus up to 14% and all-cause mortality by 4%. Lifestyle changing interventions, among them promoting exercise marked by a theory of behavior change, have shown positive results. Objective: To evaluate the effect of an intervention promoting the performance of physical exercise, with specific recommendations, based on the Transtheoretical Model, on systolic blood pressure and on the amount of exercise performed (minutes/week) in patients with hypertension aged 40 to 70 years, users of primary care in the Mexican Institute for Social Security (IMSS) in Aguascalientes. Material and methods: Randomized clinical trial, in which 442 patients with hypertension will participate. The control group will receive conventional care and recommendations for physical exercise and diet. The intervention group, in addition, will attend 6 workshops, one a month, which will promote performing physical exercise, with access given to videos of physical exercise routines, designed to gradually increase the exercise performed. At the start and end of the study, blood pressure, anthropometric measurements will be taken, through a questionnaire asking about sociodemographic data, performance of physical exercise, psychosocial factors regarding physical exercise, diet and adherence to pharmacological treatment. The characteristics of the study population by group will be described, and changes between baseline and final measurements compared, intra and intergroup, in the systolic blood pressure and minutes/week of physical exercise.
This is a prospective, multicenter observational study evaluating the efficacy of ganglion stimulation (medical device) in cases of post-herpetic neuropathy. This study introduces recent methods of phenotypic stratification of postherpetic neuropathy into the field of interventional pain therapy. The aim is to identify which clinical expression of this diverse pathology can derive the greatest benefits from an otherwise effective but expensive therapy such as ganglion stimulation. The study protocol includes the application of a common clinical practice, already in use for several years at the promoting center and participating centers (as well as internationally scientifically codified). It is supported by an innovative stratification of clinical expression (phenotype of the disease), recently introduced in the literature. The study aims to identify, through careful clinical evaluation, predictive indices of the greatest success in invasive ganglion stimulation therapy, a treatment associated with significant system costs and considerable inconvenience for the patient. The results of the experimentation will allow the codification of evaluative clinical pathways to predict a higher success index in certain clinical expressions of postherpetic neuropathy compared to others. This will help reduce the costs of implant trials and enable defining the real objective of the proposed therapy in consultation with the patient.
The main aim of this study is to learn if fazirsiran is safe during long-term use in people with liver disease caused by the abnormal Z-alpha-1 antitrypsin (Z-AAT) protein. People who are currently taking part in or have completed previous fazirsiran studies (AROAAT2001 [NCT03945292] or AROAAT2002 [NCT03946449]) can continue to receive fazirsiran in this study. Participants will receive fazirsiran every 3 months for almost 2 years and will then be followed for an additional 6 months. The study may also provide information on whether fazirsiran has a long-term effect in reducing liver fibrosis or slowing down the progression of liver fibrosis in people with liver disease due to the abnormal Z-AAT protein.
Appendicectomy has been the treatment of acute appendicitis for over a hundred years. Appendicectomy, however, includes operative and postoperative risks despite being a "routine" operation. At the same time other similar intra-abdominal infections, such as diverticulitis, are treated with antibiotics. Several studies have proved promising results of the safety and efficiency of antibiotics in the treatment of acute uncomplicated appendicitis. Our previous APPAC study, published in 2015 in the Journal of American Medical Association, also proved promising results with 73% of patients with CT-diagnosed uncomplicated appendicitis treated successfully with antibiotics within one-year follow-up. None of the patients initially treated with antibiotics that later had appendectomy had major complications. The results of the APPAC trial suggest that CT proven uncomplicated acute appendicitis is not a surgical emergency and antibiotic therapy is a safe first-line treatment option. Reducing unnecessary appendectomies has also been shown to lead to significant economic savings. Already in 1886 Fitz noted that 1/3 of patients in a large series of autopsies from the pre-appendicectomy era had evidence of prior appendices inflammation suggesting spontaneous resolution of acute appendicitis. Acute appendicitis is thought to be similar to acute diverticulitis ("left-sided appendicitis") and this similarity has been shown in epidemiological studies. Recent studies have shown no benefit of antibiotic treatment in the treatment of uncomplicated diverticulitis with outpatient management without antibiotics proving safe and well-functioning. The aim of this randomised double-blinded study is to compare antibiotic therapy with placebo to evaluate the role of antibiotic therapy in the resolution of CT-diagnosed uncomplicated acute appendicitis. The hypothesis is that antibiotic therapy is necessary in the treatment of acute uncomplicated appendicitis and that antibiotic therapy is superior to spontaneous resolution (placebo) with the primary endpoint evaluated at ten days after the intervention.
This is a multicenter, randomized, open-label, parallel, active-controlled superiority clinical study conducted in early premenopausal estrogen-receptor positive breast cancer patients with CYP2D6*10 mutations. The efficacy and safety of Exemestane Tablets combined with ovarian function suppression/ablation and Tamoxifen Tablets combined with ovarian function suppression/ablation in the treatment of early premenopausal estrogen-receptor positive breast cancer patients with CYP2D6*10 mutations are compared.
The objective of this study is to assess the efficacy and safety of upadacitinib combined with topical corticosteroids (TCS) for the treatment of adolescent and adult participants with moderate to severe atopic dermatitis (AD) who are candidates for systemic therapy.
The study has two arms, where the same natural language processing (NLP) and probabilistic graphical modeling technology will be utilized on patients' report of symptoms in both arms. The clinical arm is focused on patients presenting for consultation with a gastroenterologist. The endoscopy arm is focused generally on patients presenting for a diagnostic endoscopy, with the goal of capturing Functional Gastrointestinal Disorder (FGID) patients prior to diagnosis.
In this study the investigators will assess the validity, reliability and acceptability of utilizing family members to complete a delirium screen using the Cornell Assessment of Pediatric Delirium (CAPD).
When patients have surgery on the neck, trunk, arms, or legs, stitches are the standard way to close the wound. Wounds always result in a scar, but doctors are always looking for ways to reduce scarring. Several studies have been done to test ways to close wounds that reduce scarring. One idea is to reduce the tension around the cut. One way to reduce tension is to free up the skin around the wound. This procedure is also called "undermining". Some studies have shown that freeing up the skin near the tips of the wound, called the "apices," is helpful for improving the cosmetic outcome of scars. This study will investigate if there are any differences in the appearances of the scar if one tip is undermined and the other is not.
The purpose of this research is to study the efficacy of ultrasound microvessel imaging for evaluation of Chronic Kidney Disease. Definity is an ultrasound contrast agent currently approved by the FDA for use on the heart, liver, and urinary tract. This study will look at its effectiveness on the kidney.
