Hydroxychloroquine and azithromycin have been used to treat patients with coronavirus disease 2019 (Covid-19). However, evidence on the safety efficacy of these therapies is limited.We conducted a multicenter, randomized, open-label, three-group, controlled trial involving hospitalized suspected or confirmed Covid-19 who were receiving either no supplemental oxygen maximum 4 liters per minute oxygen. Patients randomly assigned in 1:1:1 ratio receive standard care, care plus...

Previous Randomised controlled trials (RCT) evaluating chloroquine and hydroxychloroquine in non-hospitalised COVID-19 patients have found no significant difference hospitalisation rates. However, low statistical power precluded definitive answers.We conducted a multicenter, double-blind, RCT 56 Brazilian sites. Adults with suspected or confirmed presenting mild moderate symptoms ≤ 07 days prior to enrollment at least one risk factor for clinical deterioration were randomised (1:1) receive...

Background: Nonsteroidal anti-inflammatory drugs (NSAIDs) are the most common type of medication used in treatment acute pain. Ketorolac trometamol (KT) is a nonnarcotic, peripherally acting nonsteroidal drug with analgesic effects comparable to certain opioids. Objective: The aim this study was compare efficacy KT and naproxen (NA) low back pain (LBP) moderate-to-severe intensity. Patients methods: In 10-day, Phase III, randomized, double-blind, double-dummy, noninferiority trial,...

<i>Background and Aims:</i> Several lines of clinical evidence support the concept that reduction blood pressure may be useful in prevention diabetic kidney disease. In young spontaneously hypertensive rats (SHR), hypertension reduces several early renal abnormalities including albuminuria. However, contribution nephrin loss to albuminuria this stage experimental diabetes is unknown. Therefore, we investigated whether elevation SHR associated with loss, if hypertension, or...
