Introduction: The COVID-19 pandemic caused a significant mortality in the world and in Ecuador. This research aimed to analyze the excess mortality due to the COVID-19 pandemic in Ecuador. Method: An observational, longitudinal, quantitative and descriptive study, classified as an ecological study in the field of epidemiology. This study focuses on measuring excess mortality during the years 2020, 2021 and 2022, using the average number of deaths that occurred in the period from 2015 to 2019 as the baseline. Results: From January 2020 to October 2022, Ecuador accumulated a total excess of deaths of 98,915. In 2020, the excess mortality was higher at 46,374, with the highest value occurring in April at 15,484. In 2021, the excess deaths amounted to 35,859, with April having the highest excess of 7,330. In 2022, the excess mortality was 16,682, with January recording the highest excess at 4,204. Conclusion: Evidence of underreporting of deaths, as well as temporal and geographi-cal variations in excess mortality, was observed. The province with the highest number of deaths and excess mortality was Guayas, followed by Pichincha. The results provide an analysis of the situation during the health emergency, emphasizing the importance of evaluating the healthcare system's capacity to respond during times of crisis and the imperative need to implement corrective measures for the future.

In Chilean children and adolescents, human papillomavirus (HPV) infection prevalence is unknown. In 2014, the HPV vaccine was incorporated into the National Immunization Program for girls, and since 2019 for boys. OBJECTIVE: To determine the prevalence, genotypes, and characteristics of HPV infection in children and adolescents with anogenital lesions not vaccinated against HPV. PATIENTS AND METHOD: Children and adolescents with anogenital lesions who consulted at the Luis Calvo Mackenna Children's Hospital between 2013 and 2017 were studied. The reason for consultation, age, sex, family history of HPV lesions, history of sexual abuse, and consensual sexual activity were recorded. HPV was detected by PCR and typification by reverse hybridization of the L1 gene. The samples were analyzed in the Oncogenic Virus Section of the Institute of Public Health. RESULTS: 110 patients were studied; 44.5% were children. HPV was detected in 34 cases (30.9% [CI95% 22.4- 40.4]), 22 (44.9%) were children and 12 (19.7%) adolescents. Eleven (91.7%) adolescents had a history of sexual con tact (p < 0.005); 4 (18.2%) children disclosed sexual abuse. HPV was found in 25% of patients with genital lesions and 50% with perianal lesions (p < 0.015). The most frequent genotypes were 59, 58, 16, 18, 6, and 11. Only low-risk genotypes were detected in children and high-risk genotypes were detected in 11/12 (91.7%) of HPV (+) adolescents. CONCLUSION: The prevalence of HPV infection was 30%. In adolescents, the infection was related to sexual contact and high-risk HPV. In children, it was associated with low-risk genotypes. Perianal lesions are more frequently associated with HPV infec tion than genital lesions in children and adolescents. The visual inspection does not allow to specify the etiology of the genital lesions, so it is necessary to perform a PCR test for HPV.

La composición química del aceite de oliva extra virgen (AOEV) se compone principalmente de triglicéridos, ácidos grasos insaturados como ácido oleico, ácido linoleico y el α-linolénico. También se destacan compuestos fenólicos de tres clases químicas: simples, secoiridoides y lignanos. En la presente revisión se analizó el consumo del AOEV en enfermedades crónicas, ciertos tipos de cáncer y en enfermedades neurodegenerativas. La evidencia muestra que el consumo de entre 8 y 40 g de AOEV diario tiene efectos protectores en enfermedades cardiovasculares, puede evitar la aparición de diabetes tipo 2 y aumentar los niveles de colesterol HDL. Respecto al cáncer, entre los efectos evaluados se destacan los encontrados a partir de los compuestos fenólicos hidroxitirosol (HT) y oleocantal, los que han demostrado un efecto protector en algunos tipos de cáncer como cáncer de piel y de mama. En las enfermedades neurodegenerativas, se observó que el consumo diario de 50 g de AOEV, tiene un efecto inhibidor en la degeneración neuronal atribuido a sus compuestos fenólicos como oleuropeina e HT. Investigaciones a futuro debieran enfocarse en determinar los efectos a largo plazo del consumo de AOEV en las diferentes enfermedades analizadas, para así poder ir estableciendo la "dosis" de AOEV que permita obtener resultados protectores sobre la salud. Además de explorar los efectos de las diferentes variedades de aceitunas (con sus componentes bioactivos particulares) con el fin de establecer los efectos en la salud y enfermedad asociados a variedades específicas.
The chemical composition of extra virgin olive oil (EVOO) is mainly composed of triglycerides, unsaturated fatty acids such as oleic acid, linoleic acid, and α-linolenic acid. Phenolic compounds of three chemical classes are also relevant, such as simple, secoiridoids, and lignans. Here, we review the association between EVOO consumption and chronic diseases, certain types of cancer, and neurodegenerative diseases. Evidence shows that consuming between 8 and 40 g of EVOO / day has protective effects on cardiovascular diseases, can prevent the onset of type 2 diabetes, and increases HDL cholesterol levels. Regarding cancer, phenolic compounds hydroxytyrosol (HT) and oleocanthal have protective effects on some types of cancer, such as skin and breast cancer. Regarding neurodegenerative diseases, daily consumption of phenolic compounds such as oleuperin and hydroxytyrosol and 50 g of EVOO has an inhibitory effect on neuronal degeneration and a protective effect on neuroprotective capacity. Future research should focus on determining the long-term impact of EVOO consumption on different diseases to establish the "dose" of EVOO that will allow health-protective results. It is also necessary to establish the effects of the specific olives (with their particular bioactive components) to establish the different impacts on health and disease associated with olives varieties.
RESUMO
PURPOSE: To assess the effect of the intake of a single dose of high-polyphenols cocoa on gene expression in peripheral mononuclear cells (PBMCs), and analyze conjugated (-)-epicatechin metabolites in plasma, which may be related with an antioxidant response in healthy human. METHODS: A randomized, controlled, double-blind, cross-over, clinical trial in healthy young adults who consumed a single dose of high-polyphenols cocoa powder and maltodextrins as control, with a one-week washout period. Analysis of circulating metabolites, plasma antioxidant capacity and gene expression changes in PBMCs were performed under fasting conditions and 2-h after treatment using microarray in a subsample. Pathway analysis was conducted using Ingenuity Pathway Analysis (IPA). RESULTS: Twenty healthy participants (9 F) were included in the study. A significant increase in circulating (-)-epicatechin metabolites was found after cocoa intake in all participants without related changes in antioxidant capacity of plasma. The metabolites profile slightly varied across subjects. Treatments triggered different transcriptional changes in PBMC. A group of 98 genes showed changes in expression after cocoa treatment, while only 18 were modified by control. Differentially expressed genes included inflammatory cytokines and other molecules involved in redox balance. Gene and network analysis after cocoa intake converged in functions annotated as decreased production of reactive oxygen species (p = 9.58E-04), decreased leukocyte activation (p = 4E-03) and calcium mobilization (p = 2.51E-05). CONCLUSIONS: No association was found between conjugated metabolites in plasma and antioxidant capacity. Changes in PBMCs gene expression suggest anti-inflammatory effects.

Frontotemporal dementia (FTD) affects behavior, language, and personality. This study aims to explore functional connectivity changes in three FTD variants: behavioral (bvFTD), semantic (svPPA), and nonfluent variant (nfvPPA). Seventy-six patients diagnosed with FTD by international criteria and thirty-two controls were investigated. Functional connectivity from resting functional magnetic resonance imaging (fMRI) was estimated for the whole brain. Two types of analysis were done: network basic statistic and topological measures by graph theory. Several hubs in the limbic system and basal ganglia were compromised in the behavioral variant apart from frontal networks. Nonfluent variants showed a major disconnection with respect to the behavioral variant in operculum and parietal inferior. The global efficiency had lower coefficients in nonfluent variants than behavioral variants and controls. Our results support an extensive disconnection among frontal, limbic, basal ganglia, and parietal hubs.

Objetivo: Describir las características sociodemográficas generales, así como algunas vinculadas con el proceso de migración y evaluar el nivel de desesperanza de los mexicanos que son deportados de los Estados Unidos de América (EE.UU) al Aeropuerto Internacional de la Ciudad de México (AICM), a través del Programa de Repatriación al Interior de México (PRIM). Métodos: Estudio descriptivo de tipo transversal en el periodo de julio a diciembre de 2015. Se aplicó en forma aleatoria, confidencial y previo consentimiento un cuestionario estructurado a migrantes mexicanos deportados a su arribo a México y provenientes de los EE.UU, se incluyó una sección de datos sociodemográficos generales; de aspectos relacionados con la migración y, se evaluó el nivel de desesperanza por medio de la Escala de Desesperanza de Beck. Resultados: Se encuestó a 367 migrantes mexicanos deportados, sólo siete fueron mujeres, la mayoría en un rango de edad de 18 a 35 años, el 23% reporta enfermedades pre-existentes, sólo el 45% tuvo un buen acceso a servicios de salud en EE.UU, el 56% ya había sido repatriado en dos o más ocasiones, el 75% había vivido más de cinco años en ese país, sólo el 13% utilizó una Ventanilla de Salud de algún consulado mexicano durante su estancia. La prevalencia de desesperanza fue del 6% en esta población. Conclusiones: El abordaje de la salud mental en poblaciones de migrantes mexicanos carece de políticas públicas. La caracterización de la población migrante repatriada debe ser el punto de partida para incidir en políticas públicas que mejoren la calidad de vida de los migrantes de retorno.
Objective: To describe some general social-demographic characteristics associated with the phenomenon of migration and assess the level of despair among Mexicans who are deported from USA to the City of Mexico International Airport through the Program of Repatriation. Methods: This is a descriptive and transversal study carried out from July to December 2015. A confidential questionnaire was randomly given, provided the previous informed consent, to Mexican migrants who had been deported from USA. Data sections on general social-demographic characteristics and migration-related issues were included. The level of despair was estimated using Beck's Despair Scale. Results: 367 deported Mexican migrants were studied. Only 7 were women. The majority were in the range of 18 to 35 years old. 23% reported having had preexisting illnesses and only 45% had access to health services in USA. 56% had previously been deported in two or more occasions. 75% had been living in USA for more than 5 years. Only 13% used the Health Window at any Mexican Consulate during their stay. The prevalence of despair was 6%. Conclusions: Addressing the condition of mental health among these populations requires further public policies and the precise identification of their characteristics should be the starting point to improve their quality of life upon return.

INTRODUCTION: Stroke is a leading cause of mortality and disability. Policosanol has been effective in brain ischemia models. The aim of this study is to investigate whether policosanol, added to aspirin therapy within 30 days of stroke onset, is better than placebo + aspirine for the long-term recovery of non-cardioembolic ischemic stroke subjects. PATIENTS AND METHODS: Randomized, double-blind, placebo-controlled study. Eighty patients (mean age: 69 years) within 30 days of onset, with a modified Rankin Scale score (mRS) 2 to 4, were included. They were randomized in two groups (policosanol + aspirine or placebo + aspirine) for 12 months. RESULTS: Policosanol + aspirine decreased significantly mean mRS from the first interim check-up (1.5 months). The treatment even improved after long-term therapy. More policosanol + aspirin (87.5%) than placebo + aspirine (0%) patients achieved mRSs <= 1. Policosanol + aspirine increased significantly Barthel Index, lowered LDL-cholesterol and increased HDL-cholesterol versus placebo + aspirin. CONCLUSIONS: Long-term (12 months) administration of policosanol + aspirin given after suffering non-cardioembolic ischemic stroke was shown to be better than placebo + aspirin in improving functional outcomes when used among patients with non-cardioembolic ischemic stroke of moderate severity.
TITLE: Efecto a largo plazo del policosanol en la recuperacion funcional de pacientes con ictus isquemico no cardioembolico: estudio de un año.Introduccion. El ictus es una causa principal de mortalidad y discapacidad. El policosanol ha sido eficaz en modelos de isquemia cerebral. Este estudio investiga si el tratamiento a largo plazo con policosanol, añadido a la terapia con acido acetilsalicilico (AAS), dentro de los 30 dias posteriores a un ictus, es mejor que el placebo + AAS en la recuperacion de los pacientes. Pacientes y metodos. Estudio aleatorizado, doble ciego, controlado con placebo. Se incluyeron 80 pacientes (edad media: 69 años) que sufrieron un ictus en los 30 dias previos y con una puntuacion de 2-4 en la escala de Rankin modificada (mRS). Se distribuyeron aleatoriamente en dos grupos y recibieron policosanol + AAS o placebo + AAS durante 12 meses. Resultados. El tratamiento con policosanol + AAS disminuyo significativamente la puntuacion en la mRS desde el primer control intermedio (1,5 meses). El efecto del tratamiento incluso mejoro con la terapia a largo plazo. El numero de pacientes que alcanzaron valores de mRS menores o iguales a 1 fue superior en el grupo de policosanol + AAS (87,5%) que en el de placebo + AAS (0%). El tratamiento con policosanol + AAS aumento significativamente el indice de Barthel, disminuyo el colesterol LDL y aumento el colesterol HDL frente a placebo + AAS. Conclusiones. El tratamiento a largo plazo (12 meses) con policosanol + AAS fue mas efectivo que el tratamiento con placebo + AAS en la recuperacion funcional de los pacientes despues de sufrir un ictus isquemico no cardioembolico de moderada gravedad.

OBJETIVO: Describir los efectos de la restricción moderada del sueño en las regiones cerebrales involucradas en los procesos de inhibición cognitiva, función motora y fluidez fonológica, utilizando imágenes por resonancia magnética funcional (RMf). Materiales y métodos: Se estableció una condición de sueño habitual y otra de restricción moderada en 12 estudiantes diestros de pre y posgrado de Medicina, de entre 20 y 40 años. En ambos estados se utilizó la prueba psicológica de atención d2 e imágenes de RMf con paradigmas de función motora, fluencia fonológica y atención del tipo inhibición de la función ejecutiva Stroop. La restricción moderada de sueño fue de al menos el 63% con respecto al sueño habitual. Resultados: Se encontraron diferencias significativas en la activación cerebral con RMf para la función motora (p<0,05) entre el ciclo de sueño regular y el de restricción moderada. La actividad cerebral en RMf con los paradigmas de atención Stroop y fluidez fonológica no mostró diferencias significativas, así como tampoco la prueba psicológica de atención d2. Discusión: Se encontró interferencia en las activaciones cerebrales de representación motora con la restricción moderada de sueño, pero no se hallaron diferencias significativas en las activaciones de atención tipo Stroop, ni en la tarea de fluencia fonológica o las pruebas de atención d2. Esto podría deberse a una insuficiente restricción del sueño o a eficientes mecanismos de compensación en los sujetos de este estudio. Conclusión: Existen diferencias en las activaciones cerebrales de representación motora en la restricción moderada del sueño medidas con RMf
OBJECTIVE: To describe the effects of moderate sleep deprivation in brain regions involved in cognitive inhibition processes, motor function, and phonological fluency using functional Magnetic Resonance Imaging (fMRI). Materials and methods: A sample of 12 under-graduate and post-graduate medical students, between 20 and 40 years, were subjected to a follow-up of the number of hours of regular sleep in order compare to a moderate sleep deprivation after a nightshift. The d2 attention test and fMRI studies were used in both groups in order to evaluate motor function, verbal fluency and cognitive inhibition, or Stroop paradigms. The moderate sleep deprivation was at least 63% with respect to the regular sleep pattern during the previous week. Results: Significant differences in brain activity were found in fMRI to measure motor function (P<0.05) comparing regular sleep cycle and moderate sleep deprivation. The brain activity with fMRI Stroop paradigms and phonological fluency showed no significant differences between the two conditions, likewise with the psychological attention test d2. Discussion: The fMRI showed interference on motor representation activations in moderate sleep deprivation. No significant differences in fMRI were found in the processes of cognitive inhibition or Stroop paradigms, in phonological fluency, or in the psychological attention test d2. These could be attributed to inadequate sleep deprivation or efficient compensation mechanisms in the subjects of this study. Conclusión: There is a difference showed in fMRI on motor representation activations in moderate sleep deprivation

Fluctuating asymmetry (FA) is a parameter to measure developmental stability in plants, which can be altered by disturbances, pollution, and biotic factors such as herbivory. We evaluated the effects of environmental stress and herbivory on the FA levels in individuals of Tibouchina heteromalla (Melastomataceae) that occur in natural and undergoing restoration areas in rupestrian grasslands at Serra do Cipó, Brasil. Individuals were collected and measured in seven restored and five natural areas, totalizing 240 individuals. We found that individuals in restored areas had greater leaf area, higher levels of insect herbivory and FA compared to individuals that occurred in natural areas. In both environments, the proportion of individuals with leaf damage caused by herbivory was higher than the proportion of undamaged individuals. In addition, FA was positively correlated with herbivory and total leaf area in both restored and natural areas. These results suggest that more favorable conditions in the restored areas enhanced leaf growth, resulting in higher FA.

En las últimas décadas la enfermería en México ha realizado investigaciones que buscan recuperar su identidad disciplinar con base en la historiografía de distintos gremios de enfermeras indagando sobre sus orígenes y antecedentes históricos para definir los elementos ontológico y epistemológicos que les caracterizan. Tal es el caso de la Enfermería Naval que a través de su historia, describe la evolución profesional como gremio, con el objetivo de construir la primera historiografía sobre la formación de enfermeras navales en el medio militarizado, contribuyendo a su vez con el acervo histórico de la enfermería en México. La historia de este gremio se construyó con base en la fenomenología descriptiva e interpretativa, para ello se efectuó análisis de contenido de fuentes históricas documentales, periódicos, fotografías, videos, microfilms, entrevistas a profundidad e inclusive una historia de vida, entre las cuales se categorizaron temas y subtemas definiendo como ejes teóricos: los orígenes de la sanidad en el ejército, la iniciación de la enfermería en la Armada y la evolución de las enfermeras navales al servicio de sus milicias. Los resultados han revelado que los cuidados de enfermería hacia las milicias marítimas en México, datan desde el siglo XVIII principalmente en los puertos de Veracruz y Acapulco; así también, que a lo largo del siglo XX mediante fenómenos sociales como: la profesionalización de los marinos militares, la Segunda Guerra Mundial, el crecimiento económico de la zona marítima mexicana, la proporción de ayuda humanitaria a población en situación de catástrofe natural y el apoyo en los procesos de seguridad nacional, es como la enfermería naval mexicana ha evolucionado su práctica profesional. Se concluye que el gremio de enfermeras navales ha evolucionado en su disciplina, a través de estudiar, adaptar y articular su práctica profesional con su población de estudio que son los cuerpos militares marítimos, incrementando su nivel educativo a partir de la existencia de su escuela y consolidando su reconocimiento en el ámbito militar mediante la adaptación de sus cuidados en cuyo ambiente, representa la parte humana de la Armada de México.
On last decades the nursing in Mexico has done research with the intention of recovering its identity as a discipline based on the historiography of different nurses guilds, inquiring about their origins and historical background in order to define the ontologic and epistemological elements that characterize them. Such is the case of the Naval Nursing that through its history, describes the professional evolution as a guild, with the objective of building the first historiography about the formation of naval nurses inside the military scope, and at the same contributing with the nursing historical heritage of Mexico. The History of this guild was constructed based on the descriptive and interpretative phenomenology, for this was performed an analysis of the content of historical documental sources, newspaper, photographs, videos, microfilms, interviews in depth and even a life story, among which topics and subtopics were categorized, defining as theoretical axis: Origins of health in the army, the beginnings of the nursing in the Army and the evolution of the naval nurses to the services of their militias. The results have revealed that the nursing attentions toward the militias in Mexico dating mainly from the XVIII century in the Veracruz and Acapulco ports; also that along the XX century due to social phenomena as: the professionalization of the marines, the Second World War, the economic growth in the Mexican maritime area, the portion of humanitarian help given to the population at natural disaster and the support on the national security process, is how the Mexican naval nursing has evolved its professional practice. I conclude that the guild of the naval nurses has evolved in its discipline, through knowing, attending and articulating its professional practice with its study population which are the maritime military corps, increasing its educational level since the foundation of its school and consolidating its recognition in the military scope through adapting its care representing the human part of the Mexican Navy. Keywords: Military, naval nursing, care.

Infectious diseases are common causes of morbidity and mortality among kidney transplant recipients. Chagas disease (CD) has been recognized as an emerging infectious complication of transplantation caused by the parasite Trypanosoma cruzi. CD is prevalent in Mexico, particularly in the southern coastal region. The impact on Mexican kidney transplant programs has not been previously studied prospectively. From 2009 through 2010, serum samples from 59 kidney transplant donors and 405 renal transplant recipients were screened for antibodies against T. cruzi. Serum was initially screened using a locally developed ELISA test; positive results were confirmed by an indirect immunofluorescense test, in accordance with Panamerican Health Organization/World Health Organization guidelines. None of the donors were seropositive for T. cruzi, while 8 (1.97%) kidney transplant recipients were confirmed to be seropositive for T. cruzi. None of them have developed clinical manifestations of CD, although specific screening of recipients was not performed. A prospective study is planned to define the epidemiology and outcome of CD among kidney transplant donors and recipients in Mexico more thoroughly.

Introduction: Functional impairment in patients with high spinal cord injuries is associated to ventilatory dysfunction due to paretic respiratory muscles, which causes alterations in the ventilatory and in the cough mechanisms. Respiratory muscle training has been studied as a therapeutic alternative for this group of patients with no conclusive results, whereas a mixed protocol, which stimulates both inspiratory and expiratory muscles, had not been previously investigated. Objective: To evaluate the effects of systematic respiratory muscle training during four months, on pulmonary function, respiratory muscles strength and effort tolerance, cough efficacy and dyspnea perception, in a group of quadriplegic patients with at least one year of evolution post injury. Method: A quasi-experimental design was used. Six adults with cervical spinal cord injuries were enlisted and incorporated in a mixed respiratory muscles training for four months. Pulmonary function, respiratory muscles strength and resistance, cough efficacy and dyspnea perception were assessed pre and post training. Results: The application of the mixed training protocol significantly improved inspiratory muscle strength (p = 0,028),respiratory muscles effort tolerance (p = 0,028) and cough efficacy (p = 0,034).The other measures did not reach statistical significance. Conclusion: Mixed(inspiratory/expiratory) muscular training, shows partially favorable results in the improvement of pulmonary function. Studies using greater numbers of patients are necessary to achieve more categorical results.
Introducción: El compromiso funcional en pacientes con lesiones medulares altas se asocia a disfunción ventilatoria por paresia de musculatura respiratoria y provoca alteraciones ventilatorias y en el mecanismo de la tos. El entrenamiento de la musculatura respiratoria ha sido analizado como alternativa terapéutica para neumo este grupo de pacientes sin resultados concluyentes, mientras que un protocolo mixto, que estimule músculos inspiratorios y espiratorios no ha sido estudiado con anterioridad. Objetivo: Evaluar la respuesta del sistema respiratorio al entrenamiento sistemático de la musculatura respiratoria durante cuatro meses, sobre la función pulmonar, fuerza y tolerancia al esfuerzo de la musculatura respiratoria, eficacia de la tos y percepción de disnea de un grupo de pacientes tetrapléjicos. Materiales y Métodos: Se aplicó un diseño cuasi-experimental. Seis pacientes con lesiones medulares cervicales de al menos un año de evolución fueron reclutados e incluidos en un programa de entrenamiento mixto de la musculatura respiratoria durante 4 meses. Se evaluó la función pulmonar, fuerza y resistencia de la musculatura respiratoria, eficacia de la tos y percepción de disnea antes y después del período de entrenamiento. Resultados: El protocolo de entrenamiento mixto aplicado incrementó significativamente la fuerza muscular inspiratoria (p= 0,028), la tolerancia al esfuerzo de los músculos respiratorios (p = 0,028) y la eficacia de la tos (p = 0,034). El incremento en todas las otras variables medidas no alcanzó significancia estadística. Conclusión: El entrenamiento muscular mixto(inspiratorio/espiratorio) muestra resultados parcialmente favorables en la mejoría de indicadores de función pulmonar. Estudios de mayor número de pacientes son necesarios para acceder a resultados más categóricos.

Objetivo: Comparar los riesgos de morbilidad neonatal entre los prematuros tardíos (PT) y neonatos de término. Método: Estudio de caso control. Se revisan fichas clínicas de partos durante el año 2007. Se excluyen neonatos con malformaciones congénitas mayores, alteración neuromuscular, embarazos múltiples y aneuploidias. Los casos corresponden a todo PT nacido durante el periodo estudiado y los controles a nacidos de término en el mismo periodo. Los resultados neonatales fueron obtenidos y los riesgos calculados usando pruebas de Chi cuadrado y exacto de Fisher. Resultados: Se identifican 1536 partos, con una tasa de PT de 7,1 por ciento (109 casos), 62 cumplieron con criterios de inclusión. El grupo control consistió en 124 partos de término. PT presentaron 2 veces más riesgo de cesárea (p=0,0094) que los de término. El riesgo de ser admitido en UCIN fue de 88 (p=0,000). Los riesgos de morbilidad neonatal fueron: SDR (OR 23; p=0,000), hipoglicemia (OR 6; p=0,014), hipocalcemia (OR 6; p=0,014), hiperbilirrubinemia (OR 28; p=0,000) y necesidad de fototerapia (OR 23; p=0,000). No hubo diferencias en la presentación de enterocolitis necrotizante (p=0,478) ni sepsis neonatal (p=0,615). La mortalidad neonatal fue significativamente superior en los PT (p=0,044). Conclusión: Los PT deben ser considerados de alto riesgo en el período neonatal. Nuestros resultados son importantes para tomar decisiones clinicas respecto al mejor momento de finalizar un embarazo con riesgo inminente de prematurez.
Objective: To compare neonatal morbidity risks between late preterm (LP) and term deliveries. Methods: Case control study. Medical records in 2007 were reviewed. Major congenital malformations, neuromuscular handicap, twin pregnancies and aneuploidies were excluded. The Study group corresponds to all LP births during that period and the control group to term deliveries in the same period. Neonatal outcomes were collected and different risks were calculated using Chi square test and Fisher exact tests. Results: 1536 deliveries with a LP rate of 7.1 percent (109 cases) were observed, 62 cases met inclusion criteria. The control group consisted in 124 single term deliveries. LP had 2 times more risk of cesarean section (p=0.0094) than term deliveries. The risk of NICU admission was 88 (p=0.000). Neonatal morbidity risks were: RDS (OR 23, p=0.000), hypoglycemia (OR 6, p=0.014), hypocalcaemia (OR 6, p=0.014), hyperbillirrubinemia (OR 28, p=0.000) and phototherapy (OR 23, p=0.000). There were no differences in necrotizing enterocolitis (p=0.478) and risk of neonatal sepsis (p=0.615). Neonatal mortality was significantly higher in LP babies (p=0.044). Conclusion: LP newborn must be considered as high risk in the neonatal period. These results are important in making clinical decisions about the better time to end pregnancy.

BACKGROUND: QEEG allows a more objective evaluation of cerebral electrical activity as well as the production of topographical maps for easier comprehension. Here we have developed qEEG norms for the first year of life using methods previously published for other age ranges, including for example, regression for Gausssianity before Z transformation. These norms constitute a non-invasive and low cost tool for the functional evaluation of the infant's brain. RESULTS: Developmental equations were obtained from 101 healthy infants recording at spontaneous quiet sleep stage II. Polynomial regression equations, with age as independent variable, were calculated for full Broad Band Spectral Parameters (BBSP) using the Least Squares technique. Interpolated maps of the BBSP values or their Z transformation were constructed for linked-ear reference, average reference and Laplacian montages. All montages produced similar tendency curves and Z maps of absolute and relative power, and mean frequency at all frequency bands. The norms obtained were validated against an independent group of 50 healthy infants and some pathological cases. 91-98% of cases were well classified as normal across all measures and montages. To exemplify, two pathological cases are presented of which their qEEG maps show resemblance to CT and MRI. CONCLUSIONS: These qEEG norms are highly useful as an aid to visual interpretation and for the study of pathology further evolution as well as for assessment of infants showing brain risk factors. To our knowledge this is the first normative qEEG study for the initial year of life with such large sample and validation-group.

BACKGROUND: CD4(+)CD25(+)Foxp3(+) regulatory T cells (Treg) play an essential role in immune tolerance, suppressing responses against self-antigens. Additionally, Treg play an important role in maintaining immunosuppression to alloantigens as well as to other antigens. It is well known that in the gut, a subset of dendritic cells produces retinoic acid (RA), which together with transforming growth factor (TGF-beta) is able to differentiate naïve T cells into Treg. The aim of this study was to establish the role of antigen-presenting cells (APC) in the differentiation of allogeneic Tregs under the effect of RA and TGF-beta. METHODS: Splenic CD4(+)CD25(-) naïve T cells from C57BL/6 mice were co-cultured with splenic CD11c-enriched APC from Balb/c mice in the presence of TGF-beta, RA, and interleukin (IL-2). After 6 days of culture, cells were analyzed for the expression of Foxp3 by flow cytometry. Additionally, we investigated the role of B cells and dendritic cells (DCs) and their stimulatory capacity in the generation of Tregs. RESULTS: Our results showed that co-culture of naive T cells with the appropriate level of stimulation by APC in the presence of TGF-beta, RA, and IL-2 provided a new powerful approach to generate allogeneic Treg cells. We demonstrated that although B cells and DCs can generate Tregs by themselves, a mixure of both APC improved their capacity to efficiently generate Tregs. Also, we observed that although the addition of IL-2 to the cultures was not crucial to generate Tregs, it was required to optimize their expansion and cell survival.

Hydrogen breath test (HBT) for diagnosis of lactose malabsorption (LM), is usually performed over a 180 min standard period. However, studies have suggested that extending the observation time, the sensibility of the test is improved. Aims: To determine if the time extension of the lactose hydrogen breath test, can improve sensibility of the test. Patients and method: One thousand and two hundred and ninety three patients were included, mean age 33.1 years (range: 3-90 years), 73.3 percent women, 26.8 percent were younger than 15years. Lactose HBT was performed for a standard period, which was prolonged to 240 min when patients presented a flat curve at 180 min. Results: Seven hundred and thirty one patients (56.5 percent) had a positive breath test for LM during 180 min. The extension of the HBT to 240 min showed an increase of 13.3 percent (p < 0.05) of patients with LM diagnosis. Conclusion: This study shows that an additional hour increases sensibility of the test, and decreases the false negative results.
El test de hidrógeno en aire espirado (TH2) para el diagnóstico de malabsorción de lactosa (ML) se realiza por un período estándar de 180 min. Sin embargo, se ha sugerido que estudios de mayor duración podrían mejorar la sensibilidad del test. Objetivos: Determinar si la prolongación del TH2 con lactosa, puede mejorar la sensibilidad del diagnóstico de ML. Pacientes y Métodos: Se estudiaron 1293pacientes, edad promedio 33,1 años (rango 3 a 90 años), 73.3 por ciento mujeres, 26,8 por ciento menores de15 años. Para determinar la presencia de ML se realizó el TH2 con lactosa estándar, extendiéndolo a 240 min en pacientes con una curva plana a los 180 min. Resultados: Setecientos treinta y un pacientes (56,5 por ciento) tuvieron un TH2 concordante con ML durante el período de 180 min. En aquellos que se extendió el examen a 240 min se observó un aumento de 13,3 por ciento de ML (p< 0,05). Conclusión: Este estudio demuestra que la prolongación del TH2 en una hora mejora la sensibilidad del examen y disminuye el número de falsos negativos.
