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 involvement of the kidneys in patients infected with the SARS-CoV-2 virus at the outset of the pandemic was associated with high mortality rates worldwide. This was in part due to the generation of an inflammatory process and exacerbated oxidative stress. The present study was initiated to investigate the relationship between morphofunctional changes and gene expression in the kidney tissue of deceased Mexican patients prior to the initiation of vaccination. The investigator designed a single-center, prospective, cohort study, to analyze and relate the morphofunctional changes and gene expression of inflammatory and oxidative stress molecules in the kidney tissue of men who died from severe COVID-19. A total of 40 percutaneous renal biopsies from deceased patients with SARS-CoV-2 infection were included in the study and divided into two a groups. One group was preserved in trizol to obtain RNA and total protein, while the remaining sample was fixed in formalin to be examined by staining with hematoxylin and eosin. The histopathological analysis was conducted by an experienced nephropathologist. The expression of molecules was evaluated by real-time PCR (nphs2, slc9a1, cx3cl1, havcr1, slc22a17, sod2, egf, timp2, hmox1, fabp1, and so forth). The following biomarkers were analyzed: IL-6, Arg-1, DPP4, GSTT1, GGT1, OCL, CYP3A4, and CL-8. Additionally, Western blot analysis was conducted on claudins-5, occludin, HSP70, NRF-2, SOD2, NQO1, γ-GCL, and RAGE. The estimated glomerular filtration rate (eGFR) was calculated using the CKD-EPI (2021) equation, with the subjects divided into two groups based on their eGFR: >60 or <60 ml/min/1.73 m². The statistical analysis was conducted using the Stata program and GraphPad Prism software.
In Mexico, upper lacrimal duct obstruction (ULDO) is a common pathology, and the standard surgical treatment is closed dracryointubation. Based on statistics from our headquarters, in 30% of cases there is a failure of the technique and recurrence of symptoms due to associated complications. Because of this, the application of a self-stable bicananlicular intubation set is proposed. The aim of this study is to describe the difference in efficacy and complication rate between the application of the self-stable bicanalicular intubation set II (FCI) and closed dacryointubation in patients with ULDO .
The goal of this clinical trial is to evaluate the effectiveness of vitamin D supplementation in treating neuropsychiatric symptoms and improving antioxidant levels in individuals diagnosed with post-COVID-19 condition, a state known as long-COVID. These individuals are primarily adults who have recovered from severe COVID-19 and exhibit persistent symptoms. The main questions it aims to answer are: Does vitamin D (cholecalciferol) supplementation decrease levels of anxiety and depression in patients with post-COVID-19 condition? Does vitamin D (cholecalciferol) supplementation increase glutathione peroxidase (GPx) activity in these patients? Researchers will compare the effects of daily versus bolus doses of vitamin D (cholecalciferol) to see if one method is more effective than the other in achieving sufficient vitamin D levels and improving clinical outcomes. Participants will: Be randomly assigned to receive either a daily dose or a bolus dose of vitamin D over an 8-week period. Undergo blood tests to measure biochemical markers such as interleukin-6 (IL-6) and GPx before and two months after starting supplementation. Have their lung function tested using spirometry and diffusing capacity for carbon monoxide. Complete the Hospital Anxiety and Depression Scale to assess changes in anxiety and depression levels.
Sport specialization requires an understanding of morphological variability to optimize performance. However, the current literature lacks a detailed analysis of the anthropometric profile of track and field athletes, especially in Latin America. Additionally, the five-way fractionation method of body mass has been under-documented. These gaps highlight the need for more research to maximize the potential of athletes, particularly in emerging countries like Mexico. This study aims to determine the anthropometric characteristics of elite and Olympic Mexican track and field athletes. A descriptive cross-sectional study will be conducted. Forty-three anthropometric variables will be assessed to characterize the athlete´s physical composition using the standards of the International Society for the Advancement of Kinanthropometry (ISAK). Those variables will be used to describe the anthropometric profile (Heath and Carter somatotype, body composition through five-way fractionation method, muscle bone index, muscular adipose index, sum of skinfold thicknesses, and proportionality through Ross & Wilson Phantom strategy. Correspondences of those variables will also be established among different tests and specialties: sprint, middle-distance, long-distance, endurance, combined events, jumps, and throws. This study aims to provide the opportunity to generate reliable references for high-performance Mexican athletes.
The administration of antiretroviral drugs (ART) has significantly prolonged the life expectancy of people living with human immunodeficiency virus (HIV) and delayed the progression towards Acquired Immune Deficiency Syndrome (AIDS). However, this has led to the emergence of other conditions, such as dyslipidemia, among individuals undergoing ART. Dyslipidemia is commonly managed with statin therapy, which has not been reported to have pharmacological interactions with ART. Additionally, ginkgo biloba extract (GBS) has been observed to improve blood lipid concentrations, and aerobic exercise training (EXA) interventions have shown positive modifications in these values. Given this context, the present study aims to investigate the potential positive effects of an aerobic training program and the consumption of ginkgo biloba extract on plasma lipid concentrations in HIV-positive individuals. The study seeks to provide insights into novel strategies for managing dyslipidemia in this population.
Metabolic surgery has proven to be an effective treatment for obesity, with laparoscopic sleeve gastrectomy being the most popular procedure. Omentopexy (OP) is proposed as a strategy to reduce associated complications. Objective was to determine the effectiveness of omentopexy in controlling post-surgical symptoms and to measure the need for re-intervention, leakage, bleeding, and mortality in patients undergoing laparoscopic sleeve gastrectomy.
Diabetes affects 415 million adults globally, leading to hand issues. Povidone collagen shows promise in managing tenosynovitis. A clinical trial was conduced to compared its efficacy in adults over 60. It is shown that the intervention reduces pain, improves functionality, and grip strength with no complications. Collagen povidone holds potential for treating diabetic hand issues.
Evaluate the efficiency of management with intravenous dexmedetomidine compared to intravenous ondansetron to achieve the disappearance of post-anesthetic shivering in a shorter time in the obstetric patient undergoing cesarean section under regional anesthesia.
The objective of this clinical trial is to verify the effectiveness of polyvinyl pyrrolidone collagen in all patients with symptomatic gonarthrosis grades II-IV in patients over 40 years of age. The main objectives that this study aims to answer are the following: 1. - Document the effectiveness of intra-articular polyvinylpyrrolidone collagen in the treatment of symptomatic gonarthrosis. 2. - Compare the intensity of pain, the degree of stiffness and functionality of the joint, prior to application and one month after the therapeutic intervention. 3. - Identify demographic, clinical and therapeutic factors that influence the effectiveness of intra-articular PVP collagen in the treatment of symptomatic gonarthrosis. Patients diagnosed with symptomatic gonarthrosis Grade II-IV, referred to the Physical Medicine and Rehabilitation service within 3 months, will be selected. Two study groups will be assigned: GROUP those who received intra-articular infiltration of PVP Collagen, GROUP B: patients who received conservative treatment. Through rehabilitation with a home program for one month, in both cases, ENA and the WOMAC scale will be evaluated at the beginning of the study and after 4 weeks.
The goal of this quasi-experimental trial was to evaluate the effects of non-surgical spinal decompression on disability and pain in patients with chronic low back pain and sciatica throughout a two-month follow-up, and to analyze the relationship between demographic factors and clinical outcomes after a program of non-surgical spinal decompression. The main questions it aims to answer were: - Non-surgical spinal decompression is effective to reduce pain intensity and self-reported disability in patients with chronic low back pain and sciatica? - Age, level of education and work activities are related with clinical outcome in patients treated with non-surgical spinal decompression? Participants underwent eight sessions, three per week, with the BTL-6000 spinal decompression system. The study did not have a comparison group.
