ABSTRACT

Introducción: Los factores reproductivos se asocian con cáncer de mama. Actualmente se estudia el comportamiento según subtipos moleculares. Objetivo: Establecer la prevalencia de estos subtipos y su asociación con factores reproductivos en mujeres atendidas en centros del nororiente colombiano. Método: Estudio observacional de corte transversal, en mujeres con cáncer de mama subtipos luminales y HER2 durante 2012-2021. Se indagaron variables sociodemográficas, factores reproductivos y estadio tumoral. Resultados: En total, 347 pacientes cumplieron criterios de elegibilidad, correspondiendo a luminal A el 49,8% (intervalo de confianza del 95% [IC95%]: 44,5-55,1), a luminal B el 29,1% (IC95%: 24,3-33,9) y a HER2 el 15,5% (IC95%: 11,7-19,4). Las mujeres con tumores de mama luminal B tenían más riesgo de tener estadios localmente avanzados (odds ratio [OR]: 1,83; IC95%: 1,11-3,01; p = 0,02). Agrupando los subtipos luminales frente a HER2 se encontró que el 40,72% de las pacientes con subtipos luminales no habían lactado, frente al 69,71% con HER2 (diferencia estadísticamente significativa a favor de luminal A; OR: 1,91; IC95%: 1,02-3,53; p = 0,041). Conclusiones: La prevalencia de tumores luminales es del 84,5%. Existe asociación diferencial entre el antecedente de lactancia materna y la aparición de subtipos luminales, es decir, las mujeres que no lactaron se corresponden con mayor frecuencia con HER2. No se estableció asociación con otros factores estudiados.


Introduction: Stimulus-estrogenic factors are associated with breast cancer. Currently, the behavior according to molecular subtypes is being studied. Objective: To establish the prevalence of these subtypes and their association with reproductive factors in women attended in centers in northeastern Colombia. Method: Observational cross-sectional study in women with breast cancer subtypes luminal and HER2 during 2012 -2021. Sociodemographic variables, stimulus-estrogenic factors and tumor stage were investigated. Results: In total, 347 patients met eligibility criteria, corresponding to luminal A 49.8% (95% confidence interval [95%CI]: 44.5-55.1), luminal B 29.1% (95%CI: 24.3-33.9) and HER2 15.5% (95%CI: 11.7-19.4). Women with luminal B breast tumors were at higher risk of having locally advanced stages (odds ratio [OR]: 1.83; 95%CI: 1.11-3.01; p = 0.02). Grouping the luminal subtypes versus HER2 showed that 40.72% of patients with luminal subtypes had not lactated, compared to 69.71% HER2 (statistically significant difference in favor of luminal A; OR: 1.91; 95%CI: 1.02-3.53; p = 0.041). Conclusions: The prevalence of luminal tumors is 84.5%. There is a differential association between the history of breastfeeding and the appearance of luminal subtypes, i.e., women who did not breastfeed are more likely to have HER2. No association was established with other factors studied.

ABSTRACT

αKlotho (Klotho) has well established renoprotective effects; however, the molecular pathways mediating its glomerular protection remain incompletely understood. Recent studies have reported that Klotho is expressed in podocytes and protects glomeruli through auto- and paracrine effects. Here, we examined renal expression of Klotho in detail and explored its protective effects in podocyte-specific Klotho knockout mice, and by overexpressing human Klotho in podocytes and hepatocytes. We demonstrate that Klotho is not significantly expressed in podocytes, and transgenic mice with either a targeted deletion or overexpression of Klotho in podocytes lack a glomerular phenotype and have no altered susceptibility to glomerular injury. In contrast, mice with hepatocyte-specific overexpression of Klotho have high circulating levels of soluble Klotho, and when challenged with nephrotoxic serum have less albuminuria and less severe kidney injury compared to wildtype mice. RNA-seq analysis suggests an adaptive response to increased endoplasmic reticulum stress as a putative mechanism of action. To evaluate the clinical relevance of our findings, the results were validated in patients with diabetic nephropathy, and in precision cut kidney slices from human nephrectomies. Together, our data reveal that the glomeruloprotective effects of Klotho is mediated via endocrine actions, which increases its therapeutic potential for patients with glomerular diseases.

ABSTRACT

IgA nephropathy (IgAN) is the most common primary glomerulonephritis worldwide and defined by the presence of IgA-containing immune complexes in the mesangium that induce an inflammation leading to glomerulonephritis. Since we poorly understand early mechanisms of glomerular injury in IgAN we performed single-cell RNA sequencing (scRNA-seq) analysis of glomerulus-associated cells using SMARTseq2-technology at the early stage of IgAN in grouped ddY-mice. Cell-specific molecular signatures unraveled a key role of endothelial cells in the early pathogenesis of IgAN, especially in the recruitment and infiltration of immune cells. Mesangial and podocyte cells demonstrated less molecular changes. Several intra-glomerular paracrine pathways were detected, such as mesangial cell-derived Slit3 potentially activating Robo-receptors in podocyte/endothelial cells. Surprisingly, proximal tubular cells were strongly affected at the early stage and potential glomerulo-tubular cell-cell crosstalk pathways were identified. Importantly, many of the cellular transcriptomic signatures identified in this well-established mouse model were also detected in published bulk transcriptomic data in human IgAN. Moreover, we validated the functionality of key cell-cell crosstalk pathways using cell culture models, such as the effect of the Slit-Robo signalling axis. Thus, our study provides important novel molecular insights into the pathogenesis of early IgAN-associated glomerulopathy.

ABSTRACT

Inflammatory pathways are activated in most glomerular diseases but molecular mechanisms driving them in kidney tissue are poorly known. We identified retinoic acid receptor responder 1 (Rarres1) as a highly podocyte-enriched protein in healthy kidneys. Studies in podocyte-specific knockout animals indicated that Rarres1 was not needed for the normal development or maintenance of the glomerulus filtration barrier and did not modulate the outcome of kidney disease in a model of glomerulonephritis. Interestingly, we detected an induction of Rarres1 expression in glomerular and peritubular capillary endothelial cells in IgA and diabetic kidney disease, as well as in ANCA-associated vasculitis. Analysis of publicly available RNA data sets showed that the induction of Rarres1 expression was a common molecular mechanism in chronic kidney diseases. A conditional knock-in mouse line, overexpressing Rarres1 specifically in endothelial cells, did not show any obvious kidney phenotype. However, the overexpression promoted the progression of kidney damage in a model of glomerulonephritis. In line with this, conditional knock-out mice, lacking Rarres1 in endothelial cells, were partially protected in the disease model. Mechanistically, Rarres1 promoted inflammation and fibrosis via transcription factor Nuclear Factor-κB signaling pathway by activating receptor tyrosine kinase Axl. Thus, induction of Rarres1 expression in endothelial cells is a prevalent molecular mechanism in human glomerulopathies and this seems to have a pathogenic role in driving inflammation and fibrosis via the Nuclear Factor-κB signaling pathway.

ABSTRACT

Molecular characterization of the individual cell types in human kidney as well as model organisms are critical in defining organ function and understanding translational aspects of biomedical research. Previous studies have uncovered gene expression profiles of several kidney glomerular cell types, however, important cells, including mesangial (MCs) and glomerular parietal epithelial cells (PECs), are missing or incompletely described, and a systematic comparison between mouse and human kidney is lacking. To this end, we use Smart-seq2 to profile 4332 individual glomerulus-associated cells isolated from human living donor renal biopsies and mouse kidney. The analysis reveals genetic programs for all four glomerular cell types (podocytes, glomerular endothelial cells, MCs and PECs) as well as rare glomerulus-associated macula densa cells. Importantly, we detect heterogeneity in glomerulus-associated Pdgfrb-expressing cells, including bona fide intraglomerular MCs with the functionally active phagocytic molecular machinery, as well as a unique mural cell type located in the central stalk region of the glomerulus tuft. Furthermore, we observe remarkable species differences in the individual gene expression profiles of defined glomerular cell types that highlight translational challenges in the field and provide a guide to design translational studies.

ABSTRACT

In Colombia, like many countries in the world, due to the increase in population of elderly people, mistreatment has increased, which has physical, psychological and social consequences for the individual and major repercussions on society. The detection of abuse is a complex task, among other aspects, due to the concealment of victims and the lack of valid, reliable detection instruments that are in keeping with the sociocultural context. Professionals responsible for dealing with these situations must have an instrument that allows early detection. The objective of this study was to adapt and validate the Family Abuse Screening Questionnaire for Elderly People in Colombia. A cross-sectional study with mixed methods was carried out in two stages from 2017 to 2018. In the first stage, linguistic and semantic adaptation was carried out using translation, synthesis, back translation, expert analysis and pilot testing with 30 abused and non-abused elderly people. In the second stage, the validity and reliability of the questionnaire were obtained by means of an exploratory factor analysis and Cronbach's Alpha, using STATA 13. In the results, we provided a Socially and Culturally Adapted Family Abuse Screening Questionnaire for elderly people in Colombia with a Cronbach's Alpha of 0.82, sensitivity value of 86.9% (p < 0.05) and a specificity value of 84% (p < 0.05), detecting abuse with 4 or more positive responses to abuse. The application of the screening questionnaire by health and social services professionals will prevent further damage to social and physical health in the elderly people in Colombia, as well as reduce the costs of care in institutions.

ABSTRACT

Podocytes are critical for the maintenance of kidney ultrafiltration barrier and play a key role in the progression of glomerular diseases. Although mediator complex proteins have been shown to be important for many physiological and pathological processes, their role in kidney tissue has not been studied. In this study, we identified a mediator complex protein 22 (Med22) as a renal podocyte cell-enriched molecule. Podocyte-specific Med22 knockout mouse showed that Med22 was not needed for normal podocyte maturation. However, it was critical for the maintenance of podocyte health as the mice developed progressive glomerular disease and died due to renal failure. Detailed morphological analyses showed that Med22-deficiency in podocytes resulted in intracellular vacuole formation followed by podocyte loss. Moreover, Med22-deficiency in younger mice promoted the progression of glomerular disease, suggesting Med22-mediated processes may have a role in the development of glomerulopathies. This study shows for the first time that mediator complex has a critical role in kidney physiology.

ABSTRACT

BACKGROUND: Diabetic nephropathy (DN) is the most common cause of end-stage renal disease, affecting ∼30% of the rapidly growing diabetic population, and strongly associated with cardiovascular risk. Despite this, the molecular mechanisms of disease remain unknown. METHODS: RNA sequencing (RNAseq) was performed on paired, micro-dissected glomerular and tubulointerstitial tissue from patients diagnosed with DN [n = 19, 15 males, median (range) age: 61 (30-85) years, chronic kidney disease stages 1-4] and living kidney donors [n = 20, 12 males, median (range) age: 56 (30-70) years]. RESULTS: Principal component analysis showed a clear separation between glomeruli and tubulointerstitium transcriptomes. Differential expression analysis identified 1550 and 4530 differentially expressed genes, respectively (adjusted P < 0.01). Gene ontology and Kyoto Encyclopedia of Genes and Genomes enrichment analyses highlighted activation of inflammation and extracellular matrix (ECM) organization pathways in glomeruli, and immune and apoptosis pathways in tubulointerstitium of DN patients. Specific gene modules were associated with renal function in weighted gene co-expression network analysis. Increased messengerRNA (mRNA) expression of renal damage markers lipocalin 2 (LCN) and hepatitis A virus cellular receptor1 (HAVCR1) in the tubulointerstitial fraction was observed alongside higher urinary concentrations of the corresponding proteins neutrophil gelatinase-associated lipocalin (NGAL) and kidney injury molecule-1 (KIM-1) in DN patients. CONCLUSIONS: Here we present the first RNAseq experiment performed on paired glomerular and tubulointerstitial samples from DN patients. We show that prominent disease-specific changes occur in both compartments, including relevant cellular processes such as reorganization of ECM and inflammation (glomeruli) as well as apoptosis (tubulointerstitium). The results emphasize the potential of utilizing high-throughput transcriptomics to decipher disease pathways and treatment targets in this high-risk patient population.

ABSTRACT

Sunitinib (Su) is a tyrosine kinase inhibitor with antiangiogenic and antineoplastic effects that is recommended therapy for renal cell carcinoma, gastrointestinal stromal tumors, and pancreatic neuroendocrine tumors. Arterial hypertension is one of the adverse effects observed in the treatment with Su. The aim of this work was to deepen our understanding of the underlying mechanisms involved in the development of this side effect. Studies on endothelial function, vascular remodeling and nicotinamide adenine dinucleotide phosphate oxidase (NADPH oxidase) system were carried out in thoracic aortas from rats treated with Su for three weeks. Animals subjected to Su treatment presented with increased blood pressure and reduced endothelium-dependent vasodilation, the latter being reverted by NADPH oxidase blockade. Furthermore, vascular remodeling and stronger Masson trichrome staining, together with enhanced immunofluorescence signal for collagen 1 alpha 1 (Col1α1), were observed in aortas from treated animals. These results were accompanied by a significant elevation in superoxide anion production and the activity/protein/gene expression of NADPH oxidase isoforms (NOX1, NOX2, and NOX4), which was also prevented by NOX inhibition. Furthermore, a decrease in nitric oxide (NO) levels and endothelial nitric oxide synthase (eNOS) activation was observed in aortas from Su-treated animals. All these results indicate that endothelial dysfunction secondary to changes in vascular remodeling and oxidative stress might be responsible for the typical arterial hypertension that develops following treatment with Su.

ABSTRACT

Crime victimization is one of the most pressing public health concerns in Latin America. Young people in the region are at particularly high risk of victimization. The present study examined exposure to crime victimization as a risk factor for depressive symptoms and suicidal ideation, and the protective effects of familism and social support in a community sample of Colombian college students. Data (N = 424) came from the Juventud Project (The Emergent Adults Project), a cross-sectional study of college students, 18 to 29 years old (M = 20.8, SD = 2.5; 63% female; 75.5% lived with their families), attending an urban public university in Southern Colombia. Data were collected between March and June of 2014 through anonymous, self-administered surveys. Conditional process analysis was used to test a model in which crime victimization was directly and indirectly associated with suicidal ideation via depressive symptoms, with familism and social support as moderators of this association while controlling for gender, age, and socioeconomic status. Overall, 58.9% of participants reported at least one crime victimization event in the past year. The most common types of victimization were being robbed without the threat of harm (29.8%) and being robbed with a weapon (24.8%). Male participants reported more instances of crime victimization than female participants. Levels of depressive symptoms that could be clinically significant were reported by 30.2% of participants, and suicidal ideation was reported by 31% of participants. The association between crime victimization and suicidal ideation was fully mediated by depressive symptoms. Social support, but not familism, moderated this association; social support weakened the link between depressive symptoms and suicidal ideation. Findings suggest that crime victimization may be a significant risk for depressive symptoms and suicidal ideation among college students in Colombia, and that social support may protect from the harmful mental health effects of crime victimization.

ABSTRACT

BACKGROUND: Inflammatory processes play an important role in the pathogenesis of glomerulopathies. Finding novel ways to suppress glomerular inflammation may offer a new way to stop disease progression. However, the molecular mechanisms that initiate and drive inflammation in the glomerulus are still poorly understood. METHODS: We performed large-scale gene expression profiling of glomerulus-associated G protein-coupled receptors (GPCRs) to identify new potential therapeutic targets for glomerulopathies. The expression of Gprc5b in disease was analyzed using quantitative PCR and immunofluorescence, and by analyzing published microarray data sets. In vivo studies were carried out in a podocyte-specific Gprc5b knockout mouse line. Mechanistic studies were performed in cultured human podocytes. RESULTS: We identified an orphan GPCR, Gprc5b, as a novel gene highly enriched in podocytes that was significantly upregulated in common human glomerulopathies, including diabetic nephropathy, IgA nephropathy, and lupus nephritis. Similar upregulation of Gprc5b was detected in LPS-induced nephropathy in mice. Studies in podocyte-specific Gprc5b knockout mice showed that Gprc5b was not essential for normal development of the glomerular filtration barrier. However, knockout mice were partially protected from LPS-induced proteinuria and recruitment of inflammatory cells. Mechanistically, RNA sequencing in Gprc5b knockouts mice and experiments in cultured human podocytes showed that Gpr5cb regulated inflammatory response in podocytes via NF-κB signaling. CONCLUSIONS: GPRC5b is a novel podocyte-specific receptor that regulates inflammatory response in the glomerulus by modulating the NF-κB signaling pathway. Upregulation of Gprc5b in human glomerulopathies suggests that it may play a role in their pathogenesis.

ABSTRACT

Podocytes have an important role in the pathogenesis of diabetic nephropathy (DN). Podocyte foot process effacement, mediated largely by the actin-based cytoskeleton of foot processes, is commonly detected in DN and is believed to be a key pathogenic event in the development of proteinuria. In this study, we identified coronin 2b (Coro2b), a member of known actin-regulating proteins, the coronins, as a highly podocyte-enriched molecule located at the cytoplasmic side of the apical plasma membrane. Studies in human renal biopsies show that glomerular Coro2b expression is significantly down-regulated in patients with DN. Studies in knockout mice indicate that Coro2b is not required for the development or maintenance of the glomerular filtration barrier. Moreover, inactivation of Coro2b specifically in podocytes does not affect the outcome of nephropathy in a streptozotocin-induced diabetes model. However, Coro2b seems to modulate the reorganization of foot processes under pathological conditions as Coro2b knockout podocytes are partially protected from protamine sulfate perfusion-induced foot process effacement. Taken together, our study suggests a role for Coro2b in the pathogenesis of glomerulopathies. Further studies regarding the involvement of Coro2b in podocyte health and diseases are warranted.

ABSTRACT

Introducción. En los últimos años, los problemas de salud mental durante el período prenatal se han convertido en un tema prioritario para el campo de la salud pública. A los efectos adversos que un estado de salud mental alterado representa para el bienestar de la madre y su descendencia se suma una debilidad de los sistemas de salud para dar respuesta a esta situación. En Colombia son aún inciertas las cifras de prevalencia de cualquier problema de salud mental durante la gestación, lo que dificulta la posibilidad de ofrecer una atención que considere las particularidades del contexto. El objetivo es diseñar un protocolo de tamización de depresión y ansiedad prenatal y factores de riesgo psicosocial asociados dirigido a usuarias del servicio de control prenatal de una institución hospitalaria del oriente colombiano. Metodología. La construcción del protocolo corresponde a un método formal de acuerdo a la clasificación realizada por el Ministerio de Protección Social de Colombia para las Guías de Práctica Clínica, incluye la revisión, síntesis y análisis de literatura sobre la ansiedad y la depresión prenatal (junto con los factores de riesgo psicosocial asociados) así como sobre las estrategias de detección y atención de las mismas.

Introduction. In recent years, mental health problems during the prenatal period have become a priority in the public health field. The weakness of the healthcare systems' response to this situation adds to the adverse effects that an altered state of mental health can pose for the well-being of the mother and her child. In Colombia, the figures of prevalence of any mental health problem during pregnancy are still unknown, which hinders the possibility of providing care that considers the specific nature of the context. The objective is to design a protocol to screen for depression, prenatal anxiety and related psychosocial risk factors among users of the prenatal control service of a hospital in east Colombia. Methodology. The creation of the protocol consists of a formal method in accordance with the classification carried out by the Colombian Ministry of Social Protection for the Clinical Practice Guidelines. It includes the review, summary and analysis of literature on prenatal depression and anxiety (together with the related psychosocial risk factors), as well as the detection and response strategies for them. This review served as a basis to prepare a preliminary version of the protocol, which was subject to an external review to verify its validity, clarity and suitability, before proceeding with the design of the final version. Results. In accordance with the literature, the protocol includes the application of instruments to identify symptoms of anxiety and depression, as well as related psychosocial risk factors, such as sociodemographic variables (age, level of education, occupation and financial income); the perceived social support and quality of the couple relationship; personal and family psychological and psychiatric history; factors related to pregnancy, such as previous complications or negative experiences; personality characteristics; and experience of adverse and stressful life events. Conclusions. The protocol responds to the gap in the identification of and response to mental health problems among pregnant women. Cómo citar. Mojica-Perilla M, Parra-Villa Y, Osma-Zambrano SE.

Introdução. Nos últimos anos, problemas de saúde mental durante o pré-natal vêm se tornando uma questão prioritária no campo da saúde pública. Somado aos efeitos adversos que um estado alterado de saúde mental representa para o bem-estar da mãe e de seus filhos, encontra-se uma fraqueza dos sistemas de saúde para responder a esta situação. Na Colômbia, as taxas de prevalência de qualquer problema de saúde mental durante a gravidez ainda são incertas, o que dificulta oferecer cuidados que considerem as particularidades do contexto. O objetivo é elaborar um protocolo de triagem para depressão e ansiedade pré-natal e fatores de risco psicossociais associados, direcionado a usuárias do serviço de controle pré-natal de um hospital no leste da Colômbia. Metodologia. A elaboração do protocolo corresponde a um método formal. De acordo com a classificação feita pelo Ministério da Proteção Social da Colômbia para as Diretrizes de Prática Clínica, inclui a revisão, síntese e análise da literatura sobre ansiedade e depressão pré-natal (juntamente com os fatores de risco psicossociais associados), bem como sobre suas estratégias de detecção e atenção. Esta revisão serviu de base para a elaboração de uma versão preliminar do protocolo que foi submetida a uma revisão externa para verificar sua validade, clareza e aplicabilidade, antes de prosseguir com a elaboração da versão final. Resultados. De acordo com o relatado na literatura, o protocolo inclui a aplicação de instrumentos para identificação de sintomas de ansiedade, depressão e fatores de risco psicossociais associados, como variáveis sociodemográficas (idade, escolaridade, ocupação e renda econômica), a identificação de apoio social e a qualidade do relacionamento do casal, antecedentes psicológicos e psiquiátricos pessoais e familiares, fatores relacionados à gravidez, como complicações ou experiências negativas anteriores, características da personalidade e vivência de eventos adversos e estressantes da vida. Conclusões. O protocolo responde à lacuna de identificação e atenção aos problemas de saúde mental de mulheres grávidas. Cómo citar. Mojica-Perilla M, Parra-Villa Y, Osma-Zambrano SE.

Introduction. Depression and anxiety are common in women of childbearing age and are associated with adverse perinatal outcomes. The prevalence in Colombian population with low obstetric risk is unknown. This study seeks to determine the prevalence of depression and gestational anxiety, as well as the associated variables in women from Bucaramanga and Floridablanca (Santander). Methodology. Descriptive cross-sectional study based on a survey and the scales of Edinburgh Postnatal Depression, Zung Anxiety Self-Assessment, Family APGAR and Perceived Social Support Questionnaire. Prevalence reasons were established. Results. In 244 pregnant women with an average age of 24.8 years the prevalence of depression was 24.6%, and anxiety 25.8%. Depression is associated with a family history of depression at a prevalence rate (RP) of 2.0; presence of anxiety at RP of 22.5, and alcohol consumption at RP of 2.9. As a protective factor, it was found that the patient had two sources of income (couple and family), at RP of 0.6. Anxiety was associated with the presence of depression at RP of 13.3; the presence of psychological violence at RP of 2.3, and not having confidence in the couple, at RP of 3.4. Discussion: The study is one of the first at the local level. It allows an approach to depression and anxiety during pregnancy in a population with low obstetric risk, with findings consistent with those reported in the literature. Conclusion. Anxiety and depression are strongly associated. It is recommended to detect psychosocial morbidity. Cómo citar. Osma-Zambrano SE, Lozano-Osma MD, Mojica-Perilla M, Redondo-Rodriguez S.

ABSTRACT

Introducción. Las mujeres con depresión y ansiedad prenatal pueden sufrir problemas en su funcionamiento social, retraimiento emocional y excesiva preocupación por su habilidad futura para ejercer el rol materno. Objetivo. Identificar y describir los hallazgos reportados sobre los factores de riesgo para el desarrollo de depresión y ansiedad prenatal, las consecuencias para la madre y su descendencia, las explicaciones teóricas que abordan su génesis, mantenimiento y las estrategias de atención en salud. Metodología. Se realizó una revisión de la literatura en las bases de datos y fuentes de información: Pub Med, EBSCO Host, Scielo, Redalyc y Google Scholar, de artículos publicados entre 1995 y 2015, empleando los términos "depression during pregnancy", "antenatal anxiety", "perinatal mental health", y "prenatal anxiety" entre otros, se seleccionaron artículos que reportaran el riesgos e impactos en la salud de la madre y su descendencia, explicaciones teóricas sobre génesis y mantenimiento de la depresión y ansiedad. Resultados. El principal factor de riesgo identificado es una historia previa de ansiedad y/o depresión; entre los efectos negativos para la salud del bebe se destacan restricción en el crecimiento fetal, bajo peso al nacer, parto prematuro y a futuro problemas emocionales y conductuales del niño. Las estrategias de acción comprenden el diseño de guías y protocolos de atención clínica que permiten identificar las mujeres en riesgo y las que ya presentan una sintomatología media o severa. Conclusiones. Los anteriores resultados ponen en evidencia la necesidad de implementar estrategias de acción que permitan la identificación temprana de poblaciones en riesgo. Cómo citar.

Introduction. Women with prenatal depression and anxiety may suffer issues in their social performance, emotional withdrawal and excessive worrying about their future ability to be mothers. Objective. To identify and describe the findings that literatura reports on risk factors for developing prenatal depression and anxiety, the consequences for the mother and child, theoretical explanations that cover origin and treatment, and health care strategies. Methodology. We performed a literature review on articles published between 1995 and 2015 on the PubMed, EBSCO Host, Scielo, Redalyc and Google Scholar databases and sources of information. The terms, "depression during pregnancy," "antenatal anxiety," "perinatal mental health," and "prenatal anxiety," among others, were used. Moreover, we selected articles that reported risks and impacts on the mother and child's health, theoretical explanations on its origin and treatments for depression and anxiety. Results. The main identified risk factor is a previous history of anxiety and/or depression at some point in life. A restriction to prenatal development, a low birth weight and premature labor all stand out as some of the negative effects on the baby's health. Going forward, emotional and behavioral issues in the child stand out. Action strategies consist of designing clinical care guides and protocols that allow identifying women who are at risk and women who already present a moderate or severe symptomatology. Conclusions. The above results bring to light the need to implement action strategies that allow identifying populations at risk early. Cómo citar. Mojica-Perilla M, Redondo-Rodríguez S, Osma-Zambrano SE.

ABSTRACT

The kidney ultrafiltration barrier is formed of endothelial cells, the glomerular basement membrane and podocytes. Podocytes have a central role in normal physiology and disease pathogenesis of the glomerulus. Signaling through epidermal growth factor receptor (EGFR) in podocytes mediates development of many glomerular disease processes. In this work, we have identified zinc finger FYVE-type containing 28 (ZFYVE28) as a novel highly podocyte-enriched gene. We localize ZFYVE28 in podocyte foot processes in adult kidney. During glomerulogenesis, Zfyve28 is first expressed at the early capillary loop glomerulus. In cultured podocytes, we show that overexpression of ZFYVE28 promotes EGF-signaling, possibly by up-regulating EGFR expression and by modulating its localization. To study the role of ZFYVE28 in vivo, we generated both conventional and podocyte-specific knockout mouse lines. Kidneys developed normally in ZFYVE28-deficient mice. In adult mice, the absence of ZFYVE28 did not affect the maintenance of the filtration barrier. Moreover, ZFYVE28-deficiency did not affect the outcome of glomerular damage induced by injection of nephrotoxic serum. Taken together, we have identified Zfyve28 as a new molecular component of podocyte foot processes and show that it mediates EGF-signaling in podocytes. However, ZFYVE28 is not essential for the development or maintenance of the glomerulus filtration barrier.

ABSTRACT

Introducción: La relación docente-estudiante es fundamental para los procesos de aprendizaje y desarrollo integral de los estudiantes en el aula. Se dan dos tipos de relaciones: didáctica y socioafectiva. En este sentido, se reconoce que el desarrollo del vínculo afectivo repercute en el desarrollo humano, intelectual, académico, social y religioso. Objetivo: Determinar la relación socioafectiva docente estudiantes de preescolar y primero de primaria a través de los comportamientos del docente. Metodología: Investigación cuantitativa, de tipo descriptivo exploratorio. La muestra fue por conveniencia conformada por 14 docentes, 9 de preescolar y 5 de primero primaria de dos instituciones de la ciudad de Pasto, Colombia. El instrumento que se utilizó fue el Classroom Assessment Scoring System de Pianta el cual valora tres dominios: el apoyo emocional, organizacional y cognitivo, que contienen 9 dimensiones y con el cual se analizó tres filmaciones de clases por docente, grabadas al inicio, mediados y final del año. El equipo investigador realizó el análisis de los videos simultáneamente, para establecer un acuerdo inter jueces. Se calificó de uno a siete, siendo uno el puntaje más bajo y siete el puntaje mayor, evaluando la relación de los docentes en cada dimensión. Resultados: La relación docente-estudiante planteada por Pianta se analizó teniendo en cuenta el criterio de esfericidad de Mauchly. Es así como se observa que en ocho de las nueve dimensiones no existen diferencias significativas a lo largo del tiempo, por lo tanto las docentes mantienen la misma forma de relacionarse durante todo el año escolar en los aspectos afectivo y de aprendizaje a diferencia de la dimensión del lenguaje donde se observa que si existen diferencias significativas. Conclusiones: Para lograr el progreso positivo en la relación es indispensable involucrar el componente del afecto y la comunicación para conseguir la comprensión mutua, la percepción interpersonal y la empatía, teniendo siempre claro que el afecto mantiene una relación indisociable con la cognición.

Introduction: The teacher-student relationship is vital for the processes of learning and comprehensive development of students within the classroom. There are two types of relationships: didactic and socio-affective. In this sense, the development of the affective bond affects the human, intellectual, academic, social and religious development is recognized. Objective: To determine the teacher-child, from pre-school and first grade (elementary), socio affective relationship through teacher behavior patterns. Methodology: This is a descriptive and exploratory quantitative research. The sample was conformed by 14 teachers, 9 preschoolers, and 5 first graders from two educational institutions in the city of Pasto, Colombia. The instrument that was used was the Classroom Assessment Scoring System developed by Pianta, which evaluates three domains: emotional support, classroom organization and instructional support. These domains have also 9 dimensions. With this instrument, three recorded classes, per teacher, were analyzed. These recordings were filmed at the beginning, in the middle and at the end of the school year. The research team conducted the analysis of the videos simultaneously in order to establish an inter-judge agreement. The score was set from 1 to 7, being 1 the lowest and 7 the highest score. The purpose of this was to evaluate the teachers' relationship in each dimension. Results: The teacher-student relationship proposed by Pianta was analyzed taking into account Mauchly's sphericity test criterion. It is observed that in eight of the nine dimensions there are no significant differences over time; therefore, teachers keep the same way of being in contact with children throughout the school year in the affective and learning aspects; as opposed to the dimension of language, in which it is observed that there are significant differences indeed. Conclusions: To achieve positive progress in the relationship is essential to involve the component of affection and communication in order to accomplish a mutual understanding, an interpersonal perception and empathy; this can be achieved by having in mind that the affection maintains an unbreakable relationship with the cognitive area.

Introdução: a relação professor-aluno é fundamental para os processos de aprendizagem e desenvolvimento integral dos alunos na sala de aula. Existem dois tipos de relacionamentos: didáticos e socio-afetivos. Neste sentido, reconhece-se que o desenvolvimento do vínculo afetivo afeta o desenvolvimento humano, intelectual, acadêmico, social e religioso. Objetivo: Determinar a relação socioafetiva professora-estudante do pré-escolar e do primeiro grau, através do comportamento do professor. Metodologia: pesquisa quantitativa, tipo exploratório descritivo. A amostra foi por conveniência, composta de 14 professores, 9 de pré-escolar e 5 de primeiro grau, de duas instituições da cidade de Pasto, na Colômbia. O instrumento utilizado foi o Sistema de Pontuação de avaliação da sala de aula de Pianta que avalia três áreas: suporte emocional, organizacional e cognitivo, que contém 9 dimensões e com as quais foram analisadas três fitas de video por professor, registradas no início, no meio e no final do ano. A equipe de pesquisa realizou a análise dos vídeos simultaneamente, para estabelecer um acordo entre os juízes. Anota foi de um a sete, sendo um o de menor pontuação e sete o de maior resultado, avaliando a relação dos professores em cada dimensão. Resultados: a relação professora-aluno, proposta por Pianta, foi analisada levando em consideração o critério de esfericidade de Mauchly. É assim que se observa que em oito das nove dimensões não há diferenças significativas ao longo do tempo, portanto, os professores mantêm a mesma maneira de se relacionar ao longo do ano letivo nos aspectos afetivos e de aprendizado em oposição à dimensão da linguagem; na qual se observa que si existem diferenças significativas. Conclusões: Para alcançar um progresso positivo no relacionamento, é essencial envolver o componente de carinho e comunicação para alcançar o entendimento mútuo, a percepção interpessoal e a empatia, sendo muito claro que o carinho mantém uma relação inseparável da cognição.

ABSTRACT

Resumen Este trabajo es resultado de una investigación de corte cuantitativo y de tipo descriptivo-transversal, que buscó describir y asociar factores sociodemográficos con consumo de sustancias psicoactivas en estudiantes de una universidad privada en la ciudad de Pasto, Colombia. Para cumplir el objetivo, se diseñó y validó un cuestionario que luego se aplicó a 242 estudiantes. Los resultados mostraron que el 21,9 % ha consumido algún tipo de sustancia psicoactiva y 12,4 % reporta haberlas consumido simultáneamente con alcohol. La marihuana es la droga más consumida (11,2 %), seguida de cocaína (9,1 %). El consumo de sustancias psicoactivas se asoció significativamente con sexo, siendo los hombres quienes más consumen (p < 0,05). También se asoció con semestre y estrato socioeconómico, es decir, que el consumo de sustancias psicoactivas varía en función de estas variables. Los datos advierten que la marihuana es la principal sustancia de consumo entre universitarios, simultánea al consumo de alcohol. El impacto preventivo debe focalizarse en variables como sexo y semestre.


Abstract The purpose of this paper is to describe and associate demographic factors with psychoactive substance in students at a private university from Pasto Colombia. The results were determined through both a quantitative and descriptive analysis - transversal research. 242 students were sam pled. In order to achieve the research goal, a questionnaire was designed and validated. The results showed as follows: 21.9 % have consumed some type of psychoactive substance and 12.4 % reported having consumed this psychoactive substance with alcohol simultaneously. The results showed mari juana is the most consumed drug (11.2 %), followed by cocaine (9.1 %). Also, sex was significantly associated with psychoactive substances, being men who consume more than women (p < 0, 05). As well, psychoactive substance consumption was associated with socio economic stratum and semester, in other words varying depending on these variables. In conclusion: data warned than marihuana and alcohol simultaneously are the main psychoactive and that preventive impact must be made with a focus on variables such as gender and semester.
