There are about 3191 clinical studies being (or have been) conducted in Mexico. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
Pneumonia is one of the main causes of morbidity and mortality in the world, especially in developing countries like ours. The National Health and Nutrition Survey of Mexico, in 2006 showed underweight in 472,890 (5%) children under five years, low height in 1,194,805 (12.7%) and wasting in153,000 (1.6%) children. Zinc is decreased in malnutrition and is an essential cofactor for many proteins involved in cellular processes. Zinc deficiency leads to a decrease in the number of T cells, the ratio of Th1 to Th2 cells and the production of Th1 cytokines such as interferon gamma, with alteration in T cell mediated immunity. In malnourished children zinc supplementation restores the immune response. Reports of zinc supplementation in children with pneumonia are controversial. The aims of this study are to evaluate the immunomodulatory effect of zinc supplementation in the clinical course of children with pneumonia, to evaluate the lymphoproliferative and cytokine response in these children and to explore whether the viral or bacterial etiology is related to the clinical response to supplementation with this micronutrient. A clinical, randomized, prospective, controlled, double blinded study will be carried out. Children from 1 month to 5 years of age will be included, with the clinical and / or radiological diagnosis of pneumonia that enter the emergency room of the participant institutions. Empirical treatment for pneumonia will begin and each patient will be randomized 1:1 in 2 groups. One will receive zinc supplementation and another a placebo (glucose). Samples will be taken to determine the etiology (nasal lavage for multiplex polymerase chain reaction for 16 respiratory viruses and 6 bacteria) and a blood sample to measure the cytokine pattern and the lymphoproliferative response. After 7 days of treatment, a second sample will be taken for immunological studies (cytokine pattern and lymphoproliferative response). The following parameters will be measured to evaluate the clinical evolution: respiratory rate, temperature, oxygen saturation, inability to eat, duration of cough, rales, temperature normalization time, normalization time of oxygen saturation, normalization time of the respiratory rate, hospitalization time and outcome (discharge due to clinical improvement or death). A correlation will be made between the improvement in clinical parameters and mortality in the zinc supplementation group and the probable bacterial or viral etiology.
The application of Platelet Rich Plasma (PRP) on three occasions with an interval of 15 days between each one, is related to a decrease in the intensity of the spots and improvement in the quality of the skin of patients with melasma.
Takayasu Arteritis (TA) affects medium and large caliber arteries causing stenosis, occlusion or aneurysms. It has great predilection for the aortic arch, subclavian and extracranial arteries. The global prevalence is of 1 to 2% per million inhabitants, which varies by geographical region. The main cause of death in TA is of cardiovascular origin and includes ischemic cardiomyopathy and valvular disease. The aim of this study was to evaluate the surgical experience according to the type of surgery in subjects with TA with and without inflammatory activity. Methods: This was a retrospective, descriptive, cross-sectional study run between 1977 and 2017. Patients with Takayasu arteritis with more than 3 classification criteria according to the American College of Rheumatology (ACR) were included. The surgeries were classified as: Organ preservation, cardiac, bypass, exclusion and replacement. Inflammatory activity was evaluated.
The scorpion sting is a medical disease, for the signs and symptoms presented; Sometimes patients do not know the animal that causes these symptoms; the bibliography marks the decrease in temperature as a sign to be presented.
Thyroid diseases are pathologies that frequently affect pregnant women causing serious complications. This current research aims to find out whether the expression of TSHβX1 splice variant and D2 Thr92Ala polymorphism in the DIO2 gene are associated with thyroid disease in Mexican pregnant women.
Aim: To study the effect of a combination of functional foods on gut microbiota in subjects with metabolic syndrome. Subjects that met the metabolic syndrome criteria were enrolled in a double-blind, parallel-arm, placebo-control study. The subjects were randomized to receive a dietary portfolio (DP) or placebo (P) treatment for 2 mo. The primary endpoint was to study the effect of a DP on gut microbiota. Secondary endpoints were biochemical and anthropometric parameters, LPS, insulin, leptin, area under the curve for glucose and insulin.
Body motion evaluation (BME) by markerless systems is increasingly being considered as an alternative to traditional marker-based technology because they are faster, simpler, and less expensive. They are increasingly used in clinical settings in patients with movement disorders, however, the wide variety of systems available make results conflicting. The objective of this study was to determine if a markerless 3D motion capture system is a useful instrument to objectively differentiate between Parkinons's Disease (PD) patients with Deep Brain Stimulation (DBS) in On and Off state and controls; and its correlation with the evaluation by means of Unified Parkinson's Disease Rating Scale (UPDRS). Six PD patients who underwent DBS bilaterally in the subthalamic nucleus were evaluated using BME and UPDRS-III with DBS turned On and Off. BME of 16 different movements in six controls paired by age and sex was compared with PD patients with DBS in On and Off states. Kinematic data obtained with this markerless system could contribute to the discrimination between PD patients and healthy controls. This emerging technology may help to clinically evaluate PD patients more objectively.
The goal of this research was to relate the occurrence of post-endodontic pain after single-visit RCT using there irrigating regime. Methodology: All 216 patients had upper or lower molar, premolar or anterior teeth selected for conventional RCT for prosthetic reasons detected with only vital pulps. Of the sample of 216 teeth, were selected to just one method for instrumentation and different manner to irrigate. All instruments were used with a micro motor (VDW, Munich Germany). Reciproc instruments. Final irrigation with cold (8oC, 2.5 oC and room temperature 17% EDTA and saline solution served as a lubricants.
The goal of this clinical research was to relate the incidence of post-endodontic pain after one-visit root canal treatment using two cold protocols of irrigation. Methodology: All 240 patients had upper or lower molar, premolar or anterior teeth selected for conventional root canal treatment for prosthetic reasons detected with only vital pulps (symptomatic or asymptomatic condition). Of the sample of 240 teeth, were selected to different manner to irrigate. Reciproc instruments were used with a micro motor (VDW, Munich Germany). Final irrigation with cold (6oC, 2.5 oC and room temperature 17% EDTA and saline solution served as a lubricants.
Retrospective study with patients submitted to bariatric surgery between 2013 and 2016 at a single Institution. The objective was to analyze the incidence and causes of unexpected intraoperative findings and complications, change in surgical plan, extra surgeries and procedure interruption. All operative information was collected prospectively and aimed to describe any of the previous situations. Secondarily, a morbidity analysis was performed, correlating intraoperative complications with postoperative complications and length of stay.
