There are about 5012 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.
The purpose of this study was to evaluate the clinical performance and subjective lens handling (insertion and removal) of two toric silicone hydrogel contact lenses after one month of daily wear each.
Monocentric study of no pharmacokinetic interaction between chlorthalidone and losartan, with an open, randomized, single-dose design with four periods, four sequences and crossover in healthy volunteers, under fasting conditions, administered in fixed combination (Test product of Laboratorios Silanes, SA de CV) against the individual components administered jointly and separately (Higroton® 50, a product of Sandoz, SA de CV and Cozaar® , a product of Schering-Plow, SA de CV)
A prospective, nonrandomized, open label study to evaluate the safety and IOP lowering effectiveness of the Streamline Surgical System, in patients with mild-to-moderate open angle glaucoma undergoing cataract surgery.
Fibroblasts have demonstrated potent immune modulatory and therapeutic activity in the experimental autoimmune encephalomyelitis (EAE) model of multiple sclerosis, as well as in other models of autoimmune and inflammatory diseases. This study will assess primary safety and secondary efficacy endpoints of intravenous administration of 100 million tolerogenic fibroblasts to 5 patients with relapsing remitting MS resistant to interferon. While the safety of fibroblasts administered clinically is established, it is unknown whether these cells are effective in the treatment of multiple sclerosis (MS). Our hypothesis is that the tolerogenic fibroblasts will be well-tolerated and meet our primary objective. In addition, The investigators are optimistic that they will see signs of efficacy based on the following: Neurological assessment of the MS functional composite assessment which comprises of EDSS, the expanded EDSS (Rating Neurologic Impairment in Multiple Sclerosis, the Scripps neurological rating scale (NRS), paced auditory serial addition test (PASAT), the nine-hole peg test, and 25-foot walking time, short-form 36 (SF-36) quality of life questionnaire and gadolinium-enhanced MRI scans of the brain and cervical spinal cord.
Compare of the effectiveness of the use of ropivacaine and midazolam by intraarticular vs epidural administration on post-operative analgesia after isolated arthroscopic anterior cruciate ligament (ACL) reconstruction with hamstring autograft.
A study will be conducted with a quantitative approach with correlational scope, observational analytical study, prospective cross-sectional. The objective is to compare the levels of anxious symptomatology, depressive symptomatology and substance use in university students who were exposed to SARS-CoV-2 with those who were not.
Introduction. As the COVID-19 pandemic has continued, an increasing number of long-term complications are emerging. Recently, the appearance of characteristic pulmonary lesions has been noted, being described as post COVID-19 pneumatocele. The aim of this study is to describe the clinical, histopathologic and imaging features of post COVID-19 pneumo-hematoceles (PHC) and secondarily to suggest a treatment algorithm in these patients. Methods. A retrospective study was performed in patients admitted with diagnosis of SARS-CoV2 infection from March 2020 to September 2021 who presented PHC on imaging studies. Clinical and demographic variables were recorded and CT scans were analyzed. A logistic regression analysis was performed to determine the risk for rupture according to PHC characteristics. It appears that PHC occurs secondary to encapsulation of blood accumulation, the result of micro capillary bleeding, with partial reabsorption of blood and subsequent air filling. The recommendation is to operate on patients with PHC of 5cm and those with persistent lesions of 3cm.
The Covid-19 pandemic has generated, in the Latin American population, unprecedented levels of anxiety, depression and substance use associated with the diagnosis of the disease. Consequently, it has been pointed out that a moderating variable for the appearance of these psychological problems is high social and economic vulnerability. OBJECTIVE: To assess differences in psychological problems exposed to the diagnosis of Covid-19 by groups of countries with different incomes. METHODOLOGY: A non-experimental, correlational, prospective, double-blind, cross-sectional study was carried out using the CHERRIES methodological criteria and the sample was Latin American people. The scales used were for depression (PHQ-9), anxiety (GAD-7) and substance use (ASSIST). Likewise, Latin American countries were classified by their income level according to the World Bank. Also, the Shapiro-Wilk normality test and an ANOVA analysis of variance were performed, with Post Hoc test, with Bonferroni adjustment
Patients with chronic kidney disease (CKD) with criteria for renal replacement therapy (RRT) including uremic syndrome, have a stable state of hyperosmolarity due to urea despite not being an osmotically inactive ion. Also, these patients have alterations in urea transporters in the central nervous system (CNS) conferring a risk of neurological involvement due to an abrupt decrease in serum urea causing manifestations of the post-dialytic syndrome. Hemodialysis results in rapid removal of urea from the blood, much faster than the equilibrium rate between the brain and the bloodstream through the blood-brain barrier, resulting in an osmotic gradient that favors movement from water to the brain, causing cerebral edema, intracranial hypertension and dialysis-associated imbalance syndrome. Conventional hemodialysis (HD) uses diffusion and primarily decreases small solutes, while hemofiltration (HF) is based on convection that provides clearance mainly of medium-size molecules and small solutes with a slower rate of reduction.
The Coronavirus Disease-19 (COVID-19) pandemic is currently a priority for health services worldwide. Unlike the Severe Acute Respiratory Syndrome-Coronavirus (SARS-CoV) epidemic in 2012, the COVID-19 shows specific alterations in the white blood cell count, accentuated in severe cases, and with respiratory failure. Among the most relevant data are both lymphopenia, thrombocytopenia, and eosinopenia. The Neutrophil Lymphocyte Index has been beneficial in the evaluation of infectious respiratory processes, showing a sensitivity similar to scales such as CURB65 (Confusion, Uremia, Respiratory rate, BP, age ≥ 65 years). Because COVID-19 infection shows alterations in the blood cell ratio, these indices may be useful in evaluating patients with COVID-19 infection.
