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. Altered miRNAs expression levels have been reported in human autoimmune diseases including lupus. Variations in the expression pattern of peripheral blood circulating miRNAs specific for this class of lupus nephritis could be correlated with the pathophysiological status of this group of individuals. The aim of this study was to evaluate the relative abundance of circulating microRNAs in peripheral blood from Colombian patients with LN-IV. Circulating miRNAs in plasma of patients with diagnosis of LN-IV were compared with individuals without renal involvement (LNN group) and healthy individuals (CTL group). Total RNA was extracted from 10 ml of venous blood and subsequently sequenced using Illumina. The sequences were processed and these were analyzed using miRBase and Ensembl databases. Differential gene expression analysis was carried out with edgeR and functional analysis were done with DIANA-miRPath. Analysis was carried out using as variables of selection fold change (≥2 o ≤-2) and false discovery rate (0.05). We identified 24 circulating microRNAs with differential abundance between LN-IV and CTL groups, fourteen of these microRNAs are described for the first time to lupus nephritis (hsa-miR-589-3p, hsa-miR-1260b, hsa-miR-4511, hsa-miR-485-5p, hsa-miR-584-5p, hsa-miR-543, hsa-miR-153-3p, hsa-miR-6087, hsa-miR-3942-5p, hsa-miR-7977, hsa-miR-323b-3p, hsa-miR-4732-3p and hsa-miR-6741-3p). These changes in the abundance of miRNAs could be interpreted as alterations in the miRNAs-mRNA regulatory network in the pathogenesis of LN, preceding the clinical onset of the disease. The findings thus contribute to understanding the disease process and are likely to pave the way towards identifying disease biomarkers for early diagnosis of LN.

Critical illness in COVID-19 is an extreme and clinically homogeneous disease phenotype that we have previously shown1 to be highly efficient for discovery of genetic associations2. Despite the advanced stage of illness at presentation, we have shown that host genetics in patients who are critically ill with COVID-19 can identify immunomodulatory therapies with strong beneficial effects in this group3. Here we analyse 24,202 cases of COVID-19 with critical illness comprising a combination of microarray genotype and whole-genome sequencing data from cases of critical illness in the international GenOMICC (11,440 cases) study, combined with other studies recruiting hospitalized patients with a strong focus on severe and critical disease: ISARIC4C (676 cases) and the SCOURGE consortium (5,934 cases). To put these results in the context of existing work, we conduct a meta-analysis of the new GenOMICC genome-wide association study (GWAS) results with previously published data. We find 49 genome-wide significant associations, of which 16 have not been reported previously. To investigate the therapeutic implications of these findings, we infer the structural consequences of protein-coding variants, and combine our GWAS results with gene expression data using a monocyte transcriptome-wide association study (TWAS) model, as well as gene and protein expression using Mendelian randomization. We identify potentially druggable targets in multiple systems, including inflammatory signalling (JAK1), monocyte–macrophage activation and endothelial permeability (PDE4A), immunometabolism (SLC2A5 and AK5), and host factors required for viral entry and replication (TMPRSS2 and RAB2A).

Introducción: Adolescentes y adultos jóvenes participan frecuentemente en comportamientos sexuales riesgosos (relaciones sexuales sin protección, sexo con parejas casuales, promiscuidad, iniciación sexual temprana, etc.), trayendo consigo embarazos no planeados, Infecciones de Transmisión Sexual, suicidios, abortos, afectaciones académicas y laborales. El objetivo del estudio, fue identificar los comportamientos sexuales riesgosos y factores asociados en estudiantes de una universidad en Barranquilla, 2019. Materiales y métodos: Estudio de tipo descriptivo-correlacional de corte transversal, se utilizó la Encuesta de Riesgo Sexual, que evaluó comportamientos sexuales riesgosos en universitarios de Barranquilla, en los últimos seis meses, se generaron los coeficientes de correlación Chi cuadrado de Pearson (nivel de confianza 95%; p≤0.05) para medir la asociación entre los puntajes de riesgo sexual y factores sociodemográficos y académicos. Resultados: El 63% de los participantes inició actividad sexual antes de los 18 años. 87% han participado una o más veces en comportamientos sexuales de riesgo: sexo vaginal sin condón (73%), fellatio sin condón (60.3%), número de parejas con quién tienen comportamientos sexuales (66.2%) y experiencias sexuales inesperadas (54.4%). Los hombres y estudiantes de Derecho tenían puntajes de riesgo sexual más altos que las mujeres y los estudiantes de Enfermería. Conclusión: Los universitarios están en riesgo y participando en comportamientos sexuales riesgosos, que podrían afectar su salud y proyecto de vida. Los factores de mayor riesgo fueron; sexo temprano, género, edad >20 años, prácticas sexuales arriesgadas como el sexo vaginal, oral y anal sin protección y conductas sexuales impulsivas y no planificadas. Introduction: Adolescents and young adults are frequently involved in risky sexual behavior (unprotected sex, sex with casual partners, promiscuity, early sexual initiation, etc.) bringing with them, unplanned pregnancies, sexually transmitted infections, suicides, abortions, academic and labor affectations. The objective of the study was to identify risky sexual behaviors and associated factors in students at a university in Barranquilla, 2019.Materials and methods: Study descriptive-correlational cross-sectional, the sexual risk survey was used, which evaluated risky sexual behavior in university students of Barranquilla in the last six months, were generated correlation coefficients Chi-square Pearson (95% confidence level; p≤0.05) to measure the association between sexual risk scores and sociodemographic and academic factors.Results: 63% of participants initiated sexual activity before the age of 18. The 87% have participated one or more times in risky sexual behaviors: vaginal sex without a condom (73%), fellatio without a condom (60.3%), number of partners with whom they have sexual behaviors (66.2%) and unexpected sexual experiences (54.4%). Men and law students had higher sexual risk scores than women and nursing students.Conclusion: The university students are at risk and participating in risky sexual behavior, which could affect their health and life Project. The major risk factors were; early sex, gender, age >20 years, risky sexual practices such as vaginal, oral, and anal unprotected sex and impulsive and unplanned sexual behaviors.

INTRODUCTION: The reflection about the elements of communication that health professionals use strengthens the empathic relationship and therefore the actions that seek self-care in patients. Nursing schools must teach how to acquire competences from what should be (moral) to fully consider the emotions and needs of hospitalized children so that they can attend to the call of care. Nursing should tend to social and communication skills to offer a humanized care when children appeal to crying, to silence, to play, to attract attention. OBJECTIVE: Propose a framework of moral management of communication from the design of a functional communication structure model for the pediatric patient to come to the call of their care in a positive way. METHODOLOGY: Nature of qualitative study of descriptive type and symbolic interactionism (perceptual regression). The population was 44 nurses. The data was obtained by interviews analyzed by the STATGRAPHICS XVII Centurión Plus® and Atlas Ti 8.0 ® programs. CONCLUSION: The practices of nurses respond to the dynamics so that the child comes to the care when they are aware of the purpose of communication in strengthening the moral development of the child. A model of functional communication structure for pediatric patient care adjusted to the axioms of Paul Watzlawick is proposed.
