MicroRNAs overexpressed in Crohn's disease and their interactions with mechanisms of epigenetic regulation explain novel aspects of Crohn's disease pathogenesis.

Background: In this review, we were interested to identify the wide universe of enzymes associated with epigenetic modifications, whose gene expression is regulated by miRNAs with a high relative abundance in Crohn's disease (CD) affected tissues, with the aim to determine their impact in the pathogenesis and evolution of the disease.

Methods: We used HMDD and Bibliometrix R-package in order to identify the miRNAs overexpressed in CD. The identified enzymes associated with epigenetic mechanisms and post-translational modifications, regulated by miRNAs upregulated in CD, were analyzed using String v11 database.

Moral structuring of children during the process of obtaining informed consent in clinical and research settings.

Background: Informed consent is an important factor in a child's moral structure from which different types of doctor-patient relationships arise. Children's autonomy is currently under discussion in terms of their decent treatment, beyond what doctors and researchers perceive. To describe the influential practices that exist among clinicians and researchers toward children with chronic diseases during the process of obtaining informed consent.

Factors attributable to the cancellation of programmed surgeries.

Objective: To analyze the factors attributable to the cancellation of surgeries of a third level health institution in the city of Valledupar, Cesar / Colombia (2017-2018).

Material And Methods: Descriptive, retrospective, cross-sectional study. Data from the hospital surgical unit adverse case file were collected for 6 surgical specialties.

Epigenetic Mechanisms and Posttranslational Modifications in Systemic Lupus Erythematosus.

The complex physiology of eukaryotic cells is regulated through numerous mechanisms, including epigenetic changes and posttranslational modifications. The wide-ranging diversity of these mechanisms constitutes a way of dynamic regulation of the functionality of proteins, their activity, and their subcellular localization as well as modulation of the differential expression of genes in response to external and internal stimuli that allow an organism to respond or adapt to accordingly. However, alterations in these mechanisms have been evidenced in several autoimmune diseases, including systemic lupus erythematosus (SLE).

[Metabolic syndrome and concentrations of uric acid and ultrasensitive C-reactive protein].

Objective: To establish the prevalence of metabolic syndrome (MS) according to ATP III and its correlation with the concentration of uric acid and C-reactive protein (CRP) in people aged between 45 and 60, living in the Getsemaní neighborhood of Cartagena.

Materials And Methods: Observational, descriptive-correlational study on a population of 802 inhabitants of the Getsemaní neighborhood of Cartagena, Colombia. A random sample of 302 inhabitants was analyzed with a 95% confidence interval and 5% margin of error.

Profiling analysis of circulating microRNA in peripheral blood of patients with class IV lupus nephritis.

Renal involvement in Systemic Lupus Erythematous (SLE) patients is one of the leading causes of morbidity and a significant contributor to mortality. It's estimated that nearly 50% of SLE individuals develop kidney disease in the first year of the diagnosis. Class IV lupus nephritis (LN-IV) is the class of lupus nephritis most common in Colombian patients with SLE.
