    Objetivo: Adquirir conocimientos y así ampliar las competencias y habilidades. El grupo investigador realizó una revisión de la literatura, indagando en bases de datos científicas en un periodo comprendido entre los años 2005-2015.Metodología: Estudio cualitativo de revisión de bibliografías que consistió en la búsqueda de literatura científica; tuvo una población de 50 artículos y una muestra de 36 artículos buscadas en diferentes bases de datos. Los criterios de inclusión tenidos en cuenta para los artículos es que estos fuesen publicados en el periodo 2005-2015, escritos en idioma español, inglés o portugués. Se excluyeron estados del arte, monografías, tesis y artículos que no cumpliesen con el período de tiempo establecido.Resultados: Los estudios se basaron en variables sociodemográficas y epidemiológicas en las cuales incluyeron pacientes de todas las edades y sexos, con una población de 3294 pacientes de ambos sexos mayores. El microorganismo más frecuente fue Staphylococcus coagulasa (-), los factores de riesgo más frecuentes fueron inserción del catéter sin barreras estériles, dificultades durante la colocación, colonización bacteriana del sitio de inserción, localización de la vía en la vena femoral, nutrición parenteral total, transfusiones, permanencia del catéter por más de 7 días, diagnóstico, edad, y peso del paciente, inmunosupresión.Conclusión: Este estudio nos permite identificar las causas que pueden desencadenar una infección asociada a la atención en salud por diferentes factores referentes a la técnica de invasión por cáteter venoso central

    Cabbage and fermented vegetables : From death rate heterogeneity in countries to candidates for mitigation strategies of severe COVID-19

    Large differences in COVID-19 death rates exist between countries and between regions of the same country. Some very low death rate countries such as Eastern Asia, Central Europe, or the Balkans have a common feature of eating large quantities of fermented foods. Although biases exist when examining ecological studies, fermented vegetables or cabbage have been associated with low death rates in European countries. SARS-CoV-2 binds to its receptor, the angiotensin-converting enzyme 2 (ACE2). As a result of SARS-CoV-2 binding, ACE2 downregulation enhances the angiotensin II receptor type 1 (AT(1)R) axis associated with oxidative stress. This leads to insulin resistance as well as lung and endothelial damage, two severe outcomes of COVID-19. The nuclear factor (erythroid-derived 2)-like 2 (Nrf2) is the most potent antioxidant in humans and can block in particular the AT(1)R axis. Cabbage contains precursors of sulforaphane, the most active natural activator of Nrf2. Fermented vegetables contain many lactobacilli, which are also potent Nrf2 activators. Three examples are: kimchi in Korea, westernized foods, and the slum paradox. It is proposed that fermented cabbage is a proof-of-concept of dietary manipulations that may enhance Nrf2-associated antioxidant effects, helpful in mitigating COVID-19 severity.Peer reviewe

    Nrf2-interacting nutrients and COVID-19 : time for research to develop adaptation strategies

    There are large between- and within-country variations in COVID-19 death rates. Some very low death rate settings such as Eastern Asia, Central Europe, the Balkans and Africa have a common feature of eating large quantities of fermented foods whose intake is associated with the activation of the Nrf2 (Nuclear factor (erythroid-derived 2)-like 2) anti-oxidant transcription factor. There are many Nrf2-interacting nutrients (berberine, curcumin, epigallocatechin gallate, genistein, quercetin, resveratrol, sulforaphane) that all act similarly to reduce insulin resistance, endothelial damage, lung injury and cytokine storm. They also act on the same mechanisms (mTOR: Mammalian target of rapamycin, PPAR gamma:Peroxisome proliferator-activated receptor, NF kappa B: Nuclear factor kappa B, ERK: Extracellular signal-regulated kinases and eIF2 alpha:Elongation initiation factor 2 alpha). They may as a result be important in mitigating the severity of COVID-19, acting through the endoplasmic reticulum stress or ACE-Angiotensin-II-AT(1)R axis (AT(1)R) pathway. Many Nrf2-interacting nutrients are also interacting with TRPA1 and/or TRPV1. Interestingly, geographical areas with very low COVID-19 mortality are those with the lowest prevalence of obesity (Sub-Saharan Africa and Asia). It is tempting to propose that Nrf2-interacting foods and nutrients can re-balance insulin resistance and have a significant effect on COVID-19 severity. It is therefore possible that the intake of these foods may restore an optimal natural balance for the Nrf2 pathway and may be of interest in the mitigation of COVID-19 severity
