Abstract	Resumen: Objetivo: Efectuar una revisión sistemática de estudios originales revisados por pares que contengan datos acerca de la identificación de SARS-CoV-2 en muestras clínicas de líquido amniótico, placenta o membranas, sangre del cordón umbilical y leche humana de mujeres con diagnóstico clínico o confirmado de COVID-19. Para ser incluidos en esta revisión sistemática, los estudios debieron ser aceptados después de la publicación de la guía para el manejo de pacientes con COVID-19 de la Organización Mundial de la Salud (disponible el 13 de marzo de 2020). Resultados: Se incluyeron 17 estudios en los que se identificaron 143 muestras clínicas (38 de líquido amniótico, 34 de placentas o membranas, 39 de sangre del cordón umbilical y 32 de leche humana), de las cuales nueve resultaron positivas para ARN de SARS-CoV-2 (una de líquido amniótico obtenida antes de romper las membranas; seis de placenta o membranas, aunque los autores indican la posibilidad de contaminación por sangre materna en tres de ellas; y dos de leche humana). Conclusiones: Siguiendo nuestros criterios de búsqueda no encontramos estudios que demuestren la detección de SARS-CoV-2, a la par del aislamiento viral y la evaluación de la capacidad infectiva de las partículas virales, en muestras clínicas de líquido amniótico, placenta o membranas, sangre del cordón umbilical y leche humana, de mujeres con diagnóstico clínico o confirmado de COVID-19. Sin embargo, la transmisión vertical no puede descartarse y se requieren estudios de mayor tamaño que empleen idealmente técnicas de localización in situ de ARN y proteína de SARS-CoV-2, así como de aislamiento viral que compruebe la capacidad infectiva de las partículas virales.

Title translation	Review of new evidence about the possible vertical transmission of coronavirus disease-2019.
Abstract	Objective: To conduct a systematic review of original peer-reviewed studies, containing data on the identification of SARS-CoV-2 in clinical samples of amniotic fluid, placenta or membranes, umbilical cord blood, and human milk, from women with a clinically or confirmed diagnosis of COVID-19. These studies should have been published after the guide for the management of patients with COVID-19 from World Health Organization guide (available in March 13, 2020). Results: Seventeen studies were included, in which 143 clinical samples were identified (38 of amniotic fluid; 34 of placentas or membranes; 39 from umbilical cord blood and 32 from human milk). Among the 143 samples, nine were positive for SARS-CoV-2 RNA (one amniotic fluid sample obtained before rupturing the membranes; six samples of placenta or membranes, although authors indicate the possibility of contamination by maternal blood in three of these, and two samples of human milk). Conclusions: Following our search criteria, we found no studies that demonstrate the detection of SARS-CoV-2, in conjunction with viral isolation and the evaluation of the infective capacity of viral particles, in clinical samples of amniotic fluid, placenta or membranes, umbilical cord blood and human milk, from women with a confirmed or clinical diagnosis of COVID-19. However, vertical transmission cannot be ruled out, larger studies are required that ideally locate in situ RNA and protein of SARS-CoV-2, as well as isolation that demonstrate the infective capacity of the viral particles.

Abstract	Background: The disease Zika is considered as emergent. The infection can be acquired through different routes: a bite from the Objectives: To review published evidence of the probable transmission of Zika through human lactation. Data sources: Electronic databases: Cochrane Central Register of Controlled Trials, EBSCO, Gale, Science Direct, Scopus, US National Library of Medicine (PubMed) and Web of Science. World Health Organization and Centers for Disease Control and Prevention web pages. Study eligibility criteria: To be eligible, studies of any design had to provide primary data of human breast milk as a potential fluid for the transmission of Zika, or primary or secondary follow-up data of infants with at least one previous published study that complied with the first criterion of eligibility. Participants: Studies about women with suspected, probable or confirmed Zika during pregnancy, or the postnatal period and beyond. Studies about infants who breastfeed directly from the breast or where fed with the expressed breast milk of the suspected, probable or confirmed women with Zika. Results: This study only chose data from research papers; no patients were taken directly by the authors. A total of 1,146 were screened and nine studies were included in the qualitative synthesis, from which a total of 10 cases were identified, with documented follow-up in three of these cases. Through the timing of maternal Zika infection, five cases were classified as prenatal (time before delivery), one as immediate postnatal (period from 0 to 4 days after birth); no cases were classified as medium postnatal (period from 5 days to 8 weeks after birth); two were classified as long postnatal (period from 8 weeks to 6 months after birth) and two as beyond six months after birth. Conclusion: Human milk may be considered as a potentially infectious fluid, but we found no currently documented studies of the long-term complications in infants up to 32 months of age, with suspected, probable or confirmed Zika through human lactation, or evidence with respect to the human pathophysiology of the infection acquired through human lactation. In the light of the studies reviewed here, the World Health Organization recommendation of June 29th 2016, remains valid: "the benefits of breastfeeding for the infant and mother outweigh any potential risk of Zika virus transmission through breast milk."

Abstract	Background The disease Zika is considered as emergent. The infection can be acquired through different routes: a bite from the Aedes mosquito, sexual contact, from mother to child during pregnancy and by blood transfusion. The possibility of Zika transmission through human lactation has been considered. Zika is a disease of great concern for public health because it has been associated with neonatal and postnatal microcephaly, among other birth defects. Objectives To review published evidence of the probable transmission of Zika through human lactation. Data sources Electronic databases: Cochrane Central Register of Controlled Trials, EBSCO, Gale, Science Direct, Scopus, US National Library of Medicine (PubMed) and Web of Science. World Health Organization and Centers for Disease Control and Prevention web pages. Study eligibility criteria To be eligible, studies of any design had to provide primary data of human breast milk as a potential fluid for the transmission of Zika, or primary or secondary follow-up data of infants with at least one previous published study that complied with the first criterion of eligibility.

Abstract	BACKGROUND: Skin-to-skin contact and breastfeeding initiation within the first hour after birth are key recommendations to promote breastfeeding. In Mexico, the National Survey of Demographic Dynamics 2018, known by its Spanish acronym ENADID, collected information about breastfeeding practices. The ENADID survey is probabilistic and allows results to be generalized to the entire population in Mexico. METHODS: Information from a public database featuring 26,587 mother-baby pairs was analyzed by proportions, means and associations, as well as machine learning methods, to conduct a comparison among the pairs according to immediate skin-to-skin contact after delivery status. RESULTS: Skin-to-skin contact was described by 78.7% of the mothers and was associated with receiving an explanation regarding how to give breastmilk or the breast to the baby immediately following birth [Odds ratio (OR) 6.46; 95% Confidence Interval (CI) 6.02, 6.97], initiating breastfeeding in the first hour of life (OR 2.01; 95% CI (1.84, 2.18) and a breastfeeding duration of ≥ 6 months (OR 1.16; 95% CI 1.08, 1.25). The breastfeeding duration, in days, was greater in the group with skin-to-skin contact than in the group without skin contact. CONCLUSIONS: In Mexico, immediate and uninterrupted skin-to-skin contact between newborns and their mothers should be facilitated. Support should be provided to mothers to favor skin-to-skin contact and breasting initiation during the first hour of life, ideally through an empathic explanation by trained health personnel. Future research should focus on the evaluation of strategies to modify maternity services to facilitate immediate skin-to-skin contact after delivery and develop training programs for health personnel to support the initiation of breastfeeding during the first hour of life.

Abstract	Gel zymography quantifies the activity of certain enzymes in tumor processes. These enzymes are widely used in medical diagnosis. In order to analyze them, experts classify the zymography spots into various classes according to their tonalities. This classification is done by visual analysis, which is what makes it a subjective process. This work proposes a methodology to carry out this classifications with a process that involves an unsupervised learning algorithm in the images, denoted as the GI algorithm. With the experiments shown in this paper, this methodology could constitute a tool that bioinformatics scientists can trust to perform the desired classification since it is a quantitative indicator to order the enzymatic activity of the spots in a zymography.
