Background: Currently, periodontal treatment, both surgical and non-surgical, leaves sequelae in the vast majority of patients, dentine hypersensitivity (HSD) is one of the most important. For this reason, it is necessary to correctly diagnose this condition, to achieve a correct treatment of it. HSD is a condition frequently, which has been described as acute, provoked pain, which is not attributable to any other dental pathology. Its current prevalence is unknown, but it occurs in most patients after their periodontal treatment, and also in healthy patients. Course objective: To compare the clinical efficacy in reducing dentinal hypersensitivity in patients treated with dentifrices based on hydroxyapatite / 5% potassium nitrate / sodium monofluorophosphate 1450ppm and 5% potassium nitrate / 1426ppm sodium fluoride, during a period of evaluation of 8 weeks Materials and methods: A randomized clinical trial will be conducted. Inclusion criteria will be: patients ≥ 18 years, dentinal hypersensitivity in at least one tooth (incisors, canines, premolars) of analogous visual scale ≥4, healthy patients and patients with pathologies, controlled, absence of pathologies that contraindicate participation in the study. Exclusion criteria will include: teeth with extensive or defective fillings, tooth decay and pulpitis, dental crack, unit fixed prosthesis and plural fixed prosthesis, pregnant patients, regular anti-inflammatory treatment, allergy to any of the components of the study, hypersensitivity treatment Recent dentistry Patients will be assigned to two groups. The experimental group (n = 16) will be delivered with hydroxyapatite nanocrystals (VITIS® sensitive) and the control group (n = 16) will be given a paste with 5% potassium nitrate (Sensodyne True White), and after performing an instruction for use on the first visit, four subsequent visits will be made at 2, 4, 6 and 8 weeks after the initial visit. At each visit the hard and soft tissue exam will be performed; and also cold, heat, evaporative and electrical tests will be carried out on the teeth that will be included in the study. The tests will be performed by two previously calibrated researchers, and then the results will be entered into a computer program to perform the effectiveness calculations. Expected results: The results of the present study would demonstrate that there is a general decrease in dentinal hypersensitivity in both groups, during the 8-week study period, presenting a significantly greater improvement in dentin hypersensitivity in either of the two control groups. Keywords: Dentine hypersensitivity, desensitizing paste, hydroxyapatite, potassium nitrate.
Immune-mediated lung injury plays a pivotal role in severe interstitial pnemumonia related to SARS-CoV2 infection. Tofacitinib, a JAK1/3-Inhibitor, could mitigate alveolar inflammation by blocking IL-6 signal. The aim of this prospective single cohort open study is to test the hypotesis that early administration of tofacitinib in patients with symptomatic pneumonia could reduce pulmonary flogosis, preventing function deterioration and the need of mechanical ventilation and/or admission in intensive care units.
Aim of the study is to evaluate outcome of cataract surgery in different types of uveitis as regarding best corrected visual acuity (BCVA) and rate of post operative complications.
The new outbreak of the SARS-CoV-2 coronavirus is causing an important pandemic affecting a large number of people all-over the world. Vitamin D is a hormone precursor produced by our own body with the help of sunlight which has an important role on adaptive immunity and cellular differentiation, maturation and proliferation of several immune cells. Reduced levels of vitamin D in calves were positioned as the main cause of bovine coronavirus infection in the past. Therefore, it seems plausible that the use of vitamin D as a nutritional ergogenic aid could be a potential intervention to fight against COVID-19 infected patients which remain asymptomatic or which have non-severe and severe symptoms. This study aims to investigate whether the use of vitamin D as an immune modulator agent induces significant improvements of health status and outcomes in non-severe symptomatic patients infected with COVID-19 as well as preventing COVID-19 health deterioration. We hypothesize that vitamin D will significantly improve hard endpoints related to COVID-19 deleterious consequences compared with a usual care control group.
Study to Evaluate the Safety and Pharmacokinetics of Single-Dose Fluzoparib in Healthy Chinese Subjects
Heterozygous mutations in the ADCY5 gene cause involuntary early-onset hyperkinetic movements. In addition, patients may have associated psychiatric disorders.There is currently no treatment. As the pathophysiology is linked to ADCY5 hyperactivity, the investigative team has treated patients with caffeine, an antagonist. The investigator wishes to interview patients on the effect of caffeine on their motor symptoms and their overall clinical condition, and on the possible existence of psychiatric comorbidities using phone questionnaires.
Distal radial access (dTRA) represents a novel site for radial artery access in interventional cardiology, there is little data compare dTRA with conventional radial access (cTRA) in a randomized manner. It aims to randomly compare between the new distal radial access via the snuffbox and the conventional radial access for percutaneous coronary intervention (PCI) and angioplasty procedures. The objectives of comparing both procedures are to analyze the frequency of complications in terms of occlusion, arterial spasm, hematoma, and to weigh accesses effectiveness in terms of time and attempts to puncture, crossover rate, procedure duration, hemostasis time. Candidates for coronary angiography are being randomized into the interventional group to undergo the angiography through the distal radial artery as the access site, or the control group accessing through the radial artery. Procedural and post procedural outcomes and complications are being reported while patients are in hospital. All patients undergo doppler ultrasonography within 24 hours before and after the procedure, 4 weeks after procedure.
This randomized controled open label clinical trial is to evaluate the effect of Cyproheptadine on the clinical course of patients presenting a severe SARS-COV 2 pneumonia.
Background : Obesity prevalence rises among adults and leads to morbidity and mortality due to subsequent inflammation pathway activation. This activation is induced by higher lipid consumption which activates the Nuclear factor kappa-light-chain-enhancer of activated B cells (NF-kB) pathway and alters the microbiota profile. The Oryza sativa extract contains anthocyanin which possibly affects the microbiota composition and NF-kb pathway which eventually preserves the protective layer and tight junction of the epithelial cells. Therefore it is important to address the impact of this extract on these parameters. Objective : To assess the effect of Oryza sativa extract on microbiota profile (Lactobacillus, Firmicutes, Bacteroides, Bifidobacteria, and Escherichia coli), Lipopolysaccharide/ LPS, and the tight epithelial junction (Zonula Occludens-1) among obese adults. Method: A two-arm Quasi-Experimental will be conducted, followed by two repeated measurements, at the baseline and 3 weeks after intervention Hypothesis: Oryza sativa extract lowers the LPS level, Firmicutes sp, Bacteroides sp, and increases ZO1 protein, Bifidobacteria, and Lactobacillus sp.
This is an open-labeled, randomized, two period, single-center, crossover, comparative study, where each participant will be randomly assigned to the reference (Arcoxia®, 120 mg film-coated tablets) or the test (Etoricoxib, 120 mg film-coated tablets) formulation in each period of study (sequences Test-Reference (TR) or Reference-Test (RT)), in order to evaluate if both formulations are bioequivalent.
