There are about 4973 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.
Sleep is a physiological state that is essential for human performance, including academic, occupational, interpersonal, and psychological aspects. Sleep disruption or deprivation leads to a loss of psychomotor skills and an increased association with various diseases. Therefore, it is critical to assess how chronic sleep deprivation affects medical residents who work long shifts, including those assigned during their training.
Primary objective: To determine whether pregnancy increases the risk of recurrent CeAD and delayed stroke in women with prior CeAD based on long-term data. Methods: Multicentric, observational case-control study based on pooled individual patient data from several stroke centers. Primary endpoint: Primary composite outcome measure includes the following outcomes: (i) occurrence of recurrent CeAD, (ii) occurrence of ischemic or hemorrhagic stroke, (iii) death.
The goal of this study is to assess the safety and effectiveness of Dostarlimab compared to Placebo in adult participants with HNSCC (Head and Neck Squamous Cell Carcinoma)
In the 20th century, tobacco caused the death of 100 million people worldwide and it is estimated that it will be responsible for 1 billion deaths in the 21st century. Currently 8 million people die each year from smoking, 7 million are associated with active smoking, thus being the main risk factor for loss of disability-adjusted life years for men and the ninth most important risk factor for women. In previous studies it has been reported that approximately 21% (14%-30%) of subjects who have required hospitalization are active smokers, being higher in men than in women (28% vs 14%). The initiation of treatment for smoking cessation in this group of subjects has shown an effectiveness rate of up to 65% to maintain abstinence 6 to 12 months after discharge. The effectiveness has been analyzed in scenarios with only brief advice, in some others with the use of medications such as varenicline, bupropion and nicotine replacement therapy, however, the interventions have not been standardized for adequate analysis, which could contribute to the different results.
The goal of this clinical trial is to compare the effect of a high vitamin K diet intervention on vitamin K, insulin, osteocalcin serum levels and the cardiovascular risk percentage in normal weight and overweight or obese young adults. The main questions it aims to answer are: • Does a diet intervention containing 500mcg of vitamin K increases serum vitamin K levels? • Are vitamin K serum levels after the 500mcg of vitamin K diet intervention associated with insulin and osteocalcin serum levels or the cardiovascular risk percentage in normal weight and overweight or obese young adults? Participants will have to follow a diet intervention that contains 500mcg of vitamin K, given as a cyclic menu for 6 weeks. Also, participants will have to assist weekly to nutritional monitoring and to report any situation they observed regarding the intervention during this study. Researchers will compare normal weight and overweight or obese groups with diet intervention with normal weight and overweight or obese groups without diet intervention and only dietetic recommendations to see if vitamin K serum levels, insulin, osteocalcin and the cardiovascular risk percentage improve after the 6 weeks diet intervention.
The goal of this interventional phase III clinical trial is to evaluate objective intracranial response rate (iORR) after a treatment with total cranial radiation therapy plus concomitant transdermal nitroglycerin (NTG) addition or total cranial radiation therapy only in patients with stage IV non-small cell lung cancer with brain metastases and EGFR mutation. The main questions it aims to answer are: Determine progression-free survival (PFS) to CNS and overall survival (OS). Evaluate and compare the quality of life (QoL) of patients during and after treatment. Evaluate the cognitive function of patients before, during and after treatment. Evaluate treatment-associated toxicity to grade adverse treatment events Evaluation of HIF1α, VEGF and ROS1 in peripheral blood before and after nitroglycerin treatment. All participants will have laboratory tests at the beginning and end of radiation therapy. Cranial MRI will be performed prior to treatment and 12 weeks after the end of treatment, then every 16 weeks until intracranial progression. Patients in the interventional group will be given 36 mg patches of transdermal nitroglycerin for 24 hours with a 12-hour rest interval during treatment with radiation therapy. The control group will only receive total cranial radiation therapy at the same doses and with the same schedule.
The aim of the present study was to investigate the potential beneficial effects in volunteer young adults of orally administered L. reuteri (DSM 17938 and ATCC PTA 5289) on gingival inflammation. The null hypothesis was that no difference would be manifested by probiotic therapy regarding the conventional mechanical treatment (without probiotic administration).
Patients with rheumatic diseases (RD) have a relevant representation in the adult population in Mexico. RD are characterized by their chronic and progressive nature, which can impact functionality during the disease and can present various factors that can be associated with the presence of abuse, among others, economic dependence, decreased physical capacity, and need for care and support in different health processes. Regarding abuse in patients with RD, there is little information in the literature; however, it is possible that the prevalence could be similar to that of the occurrence in older adults since both populations share important states of vulnerability. The study aimed to identify the prevalence of abuse in patients with RD. The study will be conducted in two phases: the first one in which the GAS will be adapted for patients with RD, and this version will be validated in a population of our Institute, and the second one in which, applying the validated instrument, the magnitude of abuse is evaluated, and the factors associated with this phenomenon among patients with RD are explored.
Statins have been shown to reduce LDL cholesterol (LCLc) levels, stabilizing atheromatous plaque, reversing endothelial dysfunction and decreasing thrombogenesis. Novel pharmacological approaches, such as PCSK9 inhibitors (PCSK9i), effectively reduce LDL-c. In the clinical setting, there are cases of dyslipidemia showing lack of response to statin, known as statin-resistant familial hypercholesterolemia (SR-FH), where patients maintain a high cardiovascular risk despite statin therapy. Then, therapeutic alternatives are required. PCSK9i has shown to reduce cholesterol levels and risk of cardiovascular disease, particularly in patients with statin-resistant familial hypercholesterolemia; and recently, it has been hypothesized that PCSK9i have an effect on inflammation. Aim. To evaluate the effect of anti-PCSK9 treatment on markers related to the inflammatory response in patients with SR-FH. Methods. Non-randomized, non-controlled, before-after comparison, quasiexperimental, single-center study on patients older than 18 years, with diagnosis statin-resistant FH (SR-FH), who were attended at the Cardiology Department, Centro Médico Nacional "20 de Noviembre ISSSTE", Mexico City. SR-FH was defined as symptomatic cardiovascular disease accompanied by LDL-C concentration higher than 160 mg/dL despite maximally tolerated statin dose. Clinical-demographic and anthropometry data were collected during a direct interview. Blood sample was processed to obtain glycated hemoglobin complete blood count and serum lipids. Likewise, flow cytometry was used to characterize baseline circulating M1-, M2-macrophages and monocytes. Multiplexing of plasma samples was used to compare plasma fraktaline, IL-1, IL-4, IL-6, IL-8, IL-10, MCP-1 and TNF-alpha. Endpoints consisted of: 1) lower serum lipids; 2) modification of pro-inflammatory mediators (neutrophils, lymphocytes, NtLR, soluble pro-inflammatory cytokines). Quatitative data were resumed as mean ± SD; while categorical data as n(%).One-way T-test was applied. Statistical significance was considered if p <0.05.
This study aims to compare the success rate of external dacryocystorhinostomy with and without amniotic membranes in patients with nasolacrimal duct obstruction.
