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.
Obesity is defined as the accumulation of excessive fat, attributed to the maintenance of a positive energy imbalance between calorie intake and expenditure. Obesity contributes to the development of many comorbidities such as type 2 diabetes, cardiovascular diseases, hypertension, metabolic syndrome, and dyslipidemias, among others. Dyslipidemias indicate a high concentration of lipids in the blood. Dyslipidemias cause more than 4 million premature deaths per year. The pathogenesis of obesity is complex as it involves environmental, sociocultural, physiological, medical, behavioral, genetic, epigenetic, and many other factors. On the other hand, the causes of dyslipidemias can be: genetic / hereditary (primary dyslipidemias) or an inadequate lifestyle (secondary dyslipidemias). Sufficient evidence indicates that lifestyle, mainly diet, plays a decisive role in the development of diseases such as obesity and dyslipidemias, in addition to that, recent research shows the importance of individual genetic predisposition to suffer from diseases. Data based on genome-wide association studies suggest a genetic predisposition for obesity and dyslipidemias with identification of various genes and genetic variations associated with these conditions. In this sense, the postulates of nutrigenetics as applied science are emphasized, since it states that food components can act on the human genome, directly or indirectly, to alter the expression of genes and gene products; diet can potentially compensate or accentuate the effects of genetic polymorphisms; and the consequences of a certain diet depend on the balance of health and disease states and the genetic background of an individual. Therefore, when advising a change in diet and lifestyle as prevention and as part of the treatment for obesity and dyslipidemias, it is considered that a nutrigenetic intervention, that is, the administration of a diet designed according to genotypic characteristics and personal phenotypic, will have a much greater positive impact on the health status of people with detected genetic variations that make them susceptible to these pathologies. For this reason, the implementation of nutrigenetic interventions could be a timely and successful avant-garde treatment to mitigate various cardiometabolic diseases such as dyslipidemias and others that are highly prevalent worldwide.
This is a Phase II study with single-blinded safety phase followed by double-blinded randomization, placebo-controlled, of administration of a single dose by two different administration routes (intramuscular route or intranasal route), to evaluate immunogenicity and safety of the recombinant SARS-CoV-2 vaccine (AVX/COVID-12 vaccine) based a live Newcastle disease viral vector (rNDV) in 396 healthy subjects with evidence of prior immunity to SARS-CoV-2, followed by a booster response assessment with an intramuscular dose of COVID-19 vaccine (ChAdOx-1 -S[recombinant]) in subjects originally randomized to the placebo arm at several research sites in Mexico City.
Purpose. To evaluate the impact of pharmaceutical education in patients with Type 2 Diabetes Mellitus and Systemic Arterial Hypertension on their medication adherence. Material and research methods. Randomized clinical trial with a control group with a duration of 6 months of follow-up. Patients with a diagnosis of Type 2 Diabetes Mellitus andWE Systemic Arterial Hypertension treated in the internal medicine outpatient of a school hospital will be included. Adherence to medication will be evaluated using Morisky's 8-item medication adherence scale. The investigators believe that Pharmaceutical education increases therapeutic adherence in patients with Type 2 Diabetes Mellitus and Systemic Arterial Hypertension.
The benefits of nutritional interventions with dietary restrictions are associated with improvement and preservation of mitochondrial function. Evidence suggests that dietary restrictions, including modifications in caloric intake (caloric restriction), or in the timing of food intake (e.g., intermittent fasting), play an important role in stimulating cell and mitochondrial autophagy, favoring the elimination of old and dysfunctional mitochondria. In addition to the observed effects on mitochondrial function, there is evidence that intermittent fasting, caloric restriction, and the ketogenic diet also generate changes in gut microbiota and microbial metabolite composition. The main aim of this study is to evaluate the effect of intermittent fasting, caloric restriction and ketogenic diet on mitochondrial function determined by respirometry in monocytes, modulated by the gut microbiota in subjects with obesity. An open randomized controlled clinical trial will be conducted with 80 participants divided by a draw in 4 nutritional interventions groups for 1 month, each for 20 participants, then participants will receive 550 mg of rifaximin and will finish the study with the assigned nutritional intervention for another month of follow-up. Knowledge of these dynamics will allow us to explore and understand the relationship between metabolites from the gut microbiota and their effect on mitochondrial function associated with the dietary interventions mentioned above.
The present study has the objective of being a first approach of the full feasibility study in order to find out whether the Full Pulpotomy performed by a general practice dentist in a primary care dental clinic at the public health system with limited armamentarium could be suitable and present an appropriate success rate as well as patient satisfaction.
Background: Social isolation secondary to the pandemic can predispose the population to mental health issues in the future, especially teenagers. The Depression, Anxiety, and Stress Scale (DASS) is a valuable self-report scale since it may be used to screen for anxiety, depression, and stress in one questionnaire. In the last years, it has been observed effective in detecting these symptoms in teenagers. Aims: Identify the prevalence of depression, anxiety, and stress in high school students during the COVID-19 pandemic This is an observational cross-sectional study. For this study, the validated Spanish version of DASS-21 will be used. Qualitative variables will be evaluated through central tendencies, such as mean, standard deviation, and frequencies. The inferential analysis of categorical variables will be performed using the chi-squared test, analysis of variance (ANOVA), or Kruskal Wallis test as appropriate. For quantitative variables, Student's t-test or Mann Whitney U test will be performed depending on their distribution.
This is a randomized clinical trial across the whole of the patients who attend the HIV Unit of the Hospital Civil Viejo, a sample calculated in 43 patients for each group (intervention and control). Patients who have HIV infection and are starting antiretroviral treatment (ART), who are between 18 and 50 years old and have a mobile device, will be included in the study. The messages will consist of medical appointment reminders and adherence and motivational messages for a period of six months.
This study is open to adults with chronic kidney disease. People with and without type 2 diabetes can take part in this study. The purpose of this study is to find out whether a medicine called BI 690517 improves kidney function in people with chronic kidney disease when taken alone or in combination with a medicine called empagliflozin. In the first part of the study, participants take empagliflozin or placebo as tablets every day for 2 months. Placebo tablets look like empagliflozin tablets but do not contain any medicine. In the second part, participants are divided into several groups. Depending on the group, the participants then additionally take different doses of BI 690517 or placebo as tablets for 3.5 months. In this case, placebo tablets look like BI 690517 tablets but do not contain any medicine. Participants are in the study for about 6 months. During this time, they visit the study site about 12 times. Where possible, about 4 of the 12 visits can be done at the participant's home instead of the study site. The trial staff may also contact the participants by phone or video call. Participants collect urine samples at home. These samples are then analysed to assess kidney function. At the end of the trial the results are compared between the different groups. The doctors also regularly check participants' health and take note of any unwanted effects.
Objective: To evaluate the effectiveness of a combined strategy of human papillomavirus virus (HPV) vaccination and high-risk HPV screening to reduce the occurrence of neoplasms in the anogenital region and oral cavity among men who have sex with men, people with HIV, homeless people, transgender women, female sex workers and rape victims. Methods: This mixed methods study evaluates the effectiveness of a combined vaccination-screening strategy to reduce HPV prevalence/incidence and occurrence of cervical intraepithelial neoplasms grade 2+ and/or anal intraepithelial neoplasms grade 2+, using Kaplan-Meier. The time-to-event method will evaluate time from positive results for specific anogenital HPV to incidence of anogenital lesions containing that HPV type. Conclusions: This study will generate scientific evidence on effectiveness of a combined vaccination-screening strategy to reduce the burden of HPV-associated neoplasms within vulnerable populations in Mexico.
Drug interactions (IFF) are events that occur when multiple drugs are administered at the same time to an individual. People with arterial hypertension generally require therapeutic regimens based on 2 or more drugs for their adequate control, which makes them patients with polypharmacy. When these patients require urgent medical attention, there is a risk that IFFs will occur between their base treatment and the drugs that are prescribed to solve the added condition. Objective. To determine the frequency of pharmacological interactions between antihypertensive regimens and drugs used in the emergency service of Hospital General de Zona No 51 (HGZ 51). Material and methods: Observational, descriptive, and prospective study. The participants will be eligible patients with systemic arterial hypertension treated in the emergency room of HGZ 51 in Gómez Palacio, Durango. Support systems will be used for clinical decision, to identify potential IFFs and to be able to classify them according to their mechanism (pharmacokinetics and pharmacodynamics) and severity. A descriptive statistical analysis will be carried out in the SPSS program using measures of frequency, dispersion and central tendency.
