Achieving optimal patient safety (PS) remains a challenge in healthcare. Effective educational methods are critical for improving PS. Innovative teaching tools, like case-based learning, augmented reality, and active learning, can help students better understand and apply PS and healthcare quality improvement (HQI) principles.

DMD is a rare disorder characterized by progressive muscle degeneration and premature death. Therapy development is delayed by difficulties to monitor efficacy non-invasively in clinical trials. In this study, we used RNA-sequencing to describe the pathophysiological changes in skeletal muscle of 3 dystrophic mouse models.

The development of skills, behaviors and attitudes regarding patient safety is of utmost importance for promoting safety culture for the next generation of health professionals. This study describes our experience of implementing a course on patient safety and quality improvement for fourth year medical students in Mexico during the COVID-19 outbreak. The course comprised essential knowledge based on the patient safety curriculum provided by the WHO.

Objective: Among susceptibility genes for Sporadic Parkinson´s Disease (SPD), the MTHFR gene has been suggested as candidate. The A allele of the functional variant rs13306560 in its promoter region has been liked to decreased transactivation capacity. Therefore, we sought to determine a possible association of the rs13306560 and SPD.

Chromatin in cervical cancer (CC) undergoes chemical and structural changes that alter the expression pattern of genes. Recently, a potential mechanism, which regulates gene expression at transcriptional levels is the proteolytic clipping of histone H3. However, until now this process in CC has not been reported.

Duchenne Muscular Dystrophy (DMD) is an X-linked neuromuscular disorder in which the detection of female carriers is of the utmost importance for genetic counseling. Haplotyping with polymorphic markers and quantitation of creatine kinase levels (CK) allow tracking of the at-risk haplotype and evidence muscle damage, respectively. Such approaches are useful for carrier detection in cases of unknown mutations.

Article Synopsis
  • The study aimed to assess the role of polymorphisms in APLN and APLNR genes as potential markers for hypertension in Mexican-Mestizo patients through a case-control approach involving 400 normotensive and 383 hypertensive subjects.
  • The findings revealed that specific polymorphisms of the APLNR gene (rs7119375 and rs10501367) significantly decreased the risk of essential hypertension when adjusted for various health factors, while APLN gene polymorphisms showed no significant association.
  • Additionally, haplotype analysis indicated that the H1 haplotype increased the risk of essential hypertension, whereas the H2 haplotype decreased it, suggesting the need for further research in this area.

Background: Thyroid cancer is the most common malignancy of the endocrine system, the papillary variant accounts for 80-90% of all diagnosed cases. In the development of papillary thyroid cancer, BRAF and RAS genes are mainly affected, resulting in a modification of the system of intracellular signaling proteins known as «protein kinase mitogen-activated» (MAPK) which consist of «modules» of internal signaling proteins (Receptor/Ras/Raf/MEK/ERK) from the cell membrane to the nucleus. In thyroid cancer, these signanling proteins regulate diverse cellular processes such as differentiation, growth, development and apoptosis.

Non-invasive biological indicators of the absence/presence or progress of the disease that could be used to support diagnosis and to evaluate the effectiveness of treatment are of utmost importance in Duchenne Muscular Dystrophy (DMD). This neuromuscular disorder affects male children, causing weakness and disability, whereas female relatives are at risk of being carriers of the disease. A biomarker with both high sensitivity and specificity for accurate prediction is preferred.

Background: Polymorphisms of methylenetetrahydrofolate reductase (MTHFR) have been associated with diastolic blood pressure, hypertension, and other cardiovascular diseases; however, results of these studies are still controversial. In this study, we sought to determine whether 2 functional variants (rs1801133 and rs13306560) within the MTHFR are associated with hypertension in Mexican-Mestizos.

Methods And Results: We performed a case-control study with 1214 subjects including adults and children to test for the association of both single nucleotide polymorphisms with essential hypertension.

The Asn118Asn (rs11615) variant in the gene, and the Lys751Gln (rs13181) and Asp312Asn (rs1799793) variants in the gene have been associated with the development of varied types of cancer. The aim of the present study was to test for any association between the and gene variants and three different types of cancer in Mexican-mestizo patients. Patients and their respective controls were formed into three groups: The osteosarcoma group, with 28 patients and 97 controls; the colorectal group, with 108 patients and 119 controls; and the breast cancer group, with 71 patients and 74 controls.

Novel therapeutic approaches are emerging to restore dystrophin function in Duchenne Muscular Dystrophy (DMD), a severe neuromuscular disease characterized by progressive muscle wasting and weakness. Some of the molecular therapies, such as exon skipping, stop codon read-through and internal ribosome entry site-mediated translation rely on the type and location of mutations. Hence, their potential applicability worldwide depends on mutation frequencies within populations.

Genetic variants that confer susceptibility to Parkinson's disease (PD) show unbalanced distribution among different populations; genetic predisposition to either familial or sporadic forms of PD in Mexican-mestizo population has not been comprehensively studied. The aim of the present study was to analyze genetic variants in six PARK genes in PD patients. In total 381 individuals (173 patients, 208 controls) were genotyped for p.

Duchenne muscular dystrophy is a severe, debilitating and progressive disease that affects 1 in 3,500 live male births in the world. The diagnosis should be confirmed by genetic testing to identify the mutation in the DMD gene or muscle biopsy and immunostaining to demonstrate the absence of dystrophin. Although up to now continues to be an incurable disease, this does not mean it has no treatment.

Introduction: The muscular dystrophies (MDs) result from perturbations in the myofibers. These alterations are induced in part by mechanical stress due to membrane cell fragility, disturbances in mechanotransduction pathways, muscle cell physiology, and metabolism.

Methods: We analyzed 290 biopsies of patients with a clinical diagnosis of muscular dystrophy.

Introduction: Duchenne muscular dystrophy (DMD) is a genomic disorder characterized by progressive muscle wasting and weakness due to the absence or abnormal function of dystrophin; a protein that protects muscle cells from mechanical induced stress during contraction. Mutations in the DMD gene, may lead to different clinical phenotypes, collectively known as dystrophinopathies, of which DMD has the earliest onset and most severe progression.

Case Report: We report a novel deletion of exons 24-41, predicted to maintain the reading frame and expected to result in a mild phenotype.
