Screening for Mutations in Hereditary Cancer Susceptibility Genes in a Region with High Endogamy in Brazil.

Introduction Cancer is a multifactorial disease dependent on the influence of genetic and environmental factors. About 10% of cancers are associated with germline mutations, which predispose to a higher risk of developing cancer. Currently, the use of panels that identify susceptibility and/or association genes cancer has been increasingly used, both in clinical practice and in scientific research. Objective To investigate genetic mutations in patients with a profile for hereditary cancer in individuals from a region of northeast Brazil, where there is a high frequency of endogenous and consanguineous marriages. Methods A set of 17 genes ( BRCA1 , BRCA2 , APC , TP53 , PTEN , RET , VHL , RB1 , CDKN2 , CDH1 , CHEK2 , MLH1 , MSH2 , MSH6 , MUTYH , XPA , and XPC ) associated with cancer and hereditary syndromes were analyzed. Fifteen patients with a hereditary cancer profile were evaluated. Results The pathogenic variant found was c.1187G > A (p.Gly396Asp), rs36053993 in the MUTYH gene in a male patient diagnosed with melanoma at the age of 43 years and a family history for this tumor. This gene encodes an important enzyme related to DNA repair and has been associated with other types of cancer, this is the first report of an association with melanoma, the biological plausibility of this association is given once the MUTYH protein is expressed in the skin tissue and is responsible for repairing damage caused, for example, by sun exposure. Conclusion The results of this study suggest that this mutation may be important for the hereditary predisposition to melanoma, but a broader investigation of this mutation is needed.

Content validity of the Post-Stroke Guidance and Follow-up Booklet.

OBJECTIVES: to provide sources of content validity evidence for the Post-Stroke Guidance and Follow-up Booklet. METHODS: a quantitative-qualitative approach, using two Delphi method and content analysis rounds. The Educational Content Validation Instrument in Health was sent to 53 independent judges. A Content Validity Index above 0.90 was considered. RESULTS: of the 14 nurses who participated, 64.3% have experience with stroke care, 35.7% with primary care and 64.3% with educational material production. In content analysis, judges' suggestions were stratified into four categories: material conformation, objectivity, accuracy and perception. Spelling changes were made to the images, addition of functionality scale, adequacy of technical terms and language. The Content Validity Index in the second round showed a concordance of 0.97. CONCLUSIONS: the booklet presented satisfactory content validity sources of evidence.

Comparison of Physical and Chemical Properties of Green and Brown Brazilian Propolis Collected in Minas Gerais, Brazil.

Among the 13 types of propolis classified in Brazil according to their physicochemical properties, green propolis and brown propolis are the most commonly found and used. In this work, a comparison of the physicochemical properties of green and brown propolis produced in Minas Gerais, Brazil was performed according to the methodology established by the Brazilian legislation. And, the content of 9 bioactive compounds in the samples was determined by RP-HPLC. GrProp showed a higher content of pinocembrin, artepillin C and baccharin, and a higher quantity of total flavonoids, in comparison with BrwProp. The mechanical mass content in both types of propolis was above the limit established by legislation. However, the other physicochemical parameters were within the limits. The chemical composition, especially the flavonoid content and the free radical (DPPH) scavenger property confer to both types of propolis a promising pharmacological activity.

Clinical perspective in relation to age in patients treated with thrombectomy for anterior circulation stroke in a stroke center in Colombia.

BACKGROUND AND AIMS: Endovascular treatment for cerebrovascular disease is accepted as a first-line option with level I evidence in patients with an early and late time of window of onset symptoms, and an additional option in patients who do not respond or with contraindications to systemic thrombolysis; nevertheless the efficacy and outcomes of some groups were not clear, one of them are patients aged 80 years and older, because they were excluded of the trials, so the evidence is controversial with significant heterogeneity, for that reason in our study, we decided to analyze the age in the patients treated in our stroke center, as a predictor of prognosis, and to provide a baseline for the establishment of personalized treatment plans. METHODS: Observational, retrospective study of patients that received endovascular treatment for cerebrovascular disease in a Colombian stroke center between 2016 and 2020, continuous and categorical variables were compared using the Student's t test and Chi-Square. To determine cut-off points in the variable against death and Rankin score variable on 90th day. RESULTS: In total, 108 patients were recruited, 35 of them were of 80 or more years, and the mean age was 72.7 years, we found age as a significant variable to predict the risk in the population over 80 years of age [RR 3.37 CI (95% 1.14-103) p = 0.029]. CONCLUSIONS: Age younger than 80 is a significant predictor for results and long-term outcomes in patients suffering from stroke, and in patients older than 80 years old a Thrombolysis in Cerebral Infarction score 2b-3 is a predictor of good outcomes. Further studies are needed to evaluate the relationship between intrahospital complications and long-term outcomes.

Negative impacts of the administration of hydroxycloroquine and anticoagulant in patients with SARS-COV-2 infection: a randomized clinical trial / Impactos negativos da administração de hidroxicloroquina e anticoagulante em pacientes com infecção por SARS-COV-2: um ensaio clínico randomizado

Purpose: To evaluate antimalarial with or without anticoagulant treatment, in patients with recent SARS-COV-2 infection. Methods: Clinical study carried out at Samuel Libânio Clinic Hospital, University of Vale do Sapucaí, Pouso Alegre-MG. Approved by the Ethics Committee (4.034.077) and registered in the Clinical Trials (NCT04788355). Suspected patients for COVID-19 were included in the emergency room. The groups were: C (control) with 6 patients, A (anticoagulant apixaban) with 9 patients, H (hydroxychloroquine) with 5 patients and HA (hydroxychloroquine and anticoagulant apixaban) with 8 patients. Results: there were no significant differences between groups. The HA group, in which there was an intervention with two drugs, presented a greater number of days with symptoms (p = 0.037) and worse results, when compared to the control: most relevant symptoms, were: cough (p = 0.001), and anosmia / ageusia (p = 0.011) headache (p = 0.001). Conclusion: The present study began when there were doubts about the use of drugs such as Hydroxychloroquine (HCQ) and apixaban (APX). The reduced "n" was defined through bureaucratic and polemic issues independent of the authors' actions. No clinical benefit was associated with HCQ and APX. There was an increase in the number of symptomatic days when HCQ and APX were administered. Despite the limitations, there was no therapeutic indication of the evaluated drugs. [au]

Identification of LOC101927355 as a Novel Biomarker for Preeclampsia.

Preeclampsia, a disorder with a heterogeneous physiopathology, can be attributed to maternal, fetal, and/or placental factors. Long non-coding RNAs (lncRNAs) refer to a class of non-coding RNAs, the essential regulators of biological processes; their differential expression has been associated with the pathogenesis of multiple diseases. The study aimed to identify lncRNAs, expressed in the placentas and plasma of patients who presented with preeclampsia, as potential putative biomarkers of the disease. In silico analysis was performed to determine lncRNAs differentially expressed in the placentas of patients with preeclampsia, using a previously published RNA-Seq dataset. Seven placentas and maternal plasma samples collected at delivery from preterm preeclamptic patients (≤37 gestational weeks of gestation), and controls were used to validate the expression of lncRNAs by qRT-PCR. Six lncRNAs were validated and differentially expressed (p < 0.05) in the preeclampsia and control placentas: UCA1 and HCG4 were found upregulated, and LOC101927355, LINC00551, PART1, and NRAD1 downregulated. Two of these lncRNAs, HCG4 and LOC101927355, were also detected in maternal plasma, the latter showing a significant decrease (p = 0.03) in preeclamptic patients compared to the control group. In silico analyses showed the cytoplasmic location of LOC101927355, which suggests a role in post-transcriptional gene regulation. The detection of LOC101927355 in the placenta and plasma opens new possibilities for understanding the pathogenesis of preeclampsia and for its potential use as a biomarker.

OBJETIVO: Caso clínico de una mujer embarazada con una presentación crítica de COVID-19 y embarazo a las 25 semanas de gestación, en el contexto del peak de la pandemia en Chile en el otoño del año 2020. CASO CLÍNICO: El 20 de junio de 2020, una mujer de 34 años, con 25 semanas de embarazo, es trasladada desde Hospital de San Bernardo a Clínica Las Condes en Santiago, Chile, con un cuadro de 10 días de evolución de COVID-19, que evoluciona a una situación crítica con insuficiencia respiratoria severa. Ingresa a unidad de cuidados intensivos para ventilación mecánica. Las imágenes de radiología simple y de tomografía axial computarizada de tórax demuestran una neumopatía bilateral con imágenes características opacidades en vidrio esmerilado, asociado a engrosamiento intersticial, imágenes descritas previamente como características para COVID-19. La paciente permanece en unidad de cuidados intensivos en ventilación mecánica por siete días, con evolución favorable posterior, mejoría del cuadro séptico y alta después de 22 días de hospitalización. El parto ocurre en forma espontánea a las 38 semanas, la madre y el recién nacido evolucionan en buen estado general. El examen histopatológico placentario demuestra compromiso inflamatorio vellositario y los exámenes de anticuerpos en sangre del recién nacido demuestran la presencia de anticuerpos del tipo IgG e IgM. Se trata de uno de los pocos casos demostrados reportados de transmisión transplacentaria vía sanguínea de SARS-CoV-2 de la madre al recién nacido.

BACKGROUND: The global COVID-19 pandemic reaches the American continent in March 2020 and in less than two months it brings together more than half of the cases globally.OBJECTIVE: The clinical case of a 25-week pregnant woman with a critical presentation of COVID-19 and pregnancy at 25 weeks of gestation, is presented in the context of the peak of the pandemic in Chile in the fall of 2020. CLINICAL CASE: On June 20, 2020, a 34-year-old woman, 25 weeks pregnant, is transferred from Hospital de San Bernardo to Clinica Las Condes in Santiago, Chile, with a ten-day evolution of a COVID-19 that evolves to critical with severe respiratory failure. She is admitted to the intensive care unit for mechanical ventilation. Chest computerized axial tomography images demonstrate bilateral pneumopathy with characteristic images of ground-glass opacities, associated with interstitial thickening, images previously described as characteristics for COVID-19. The patient remains in the intensive care unit on mechanical ventilation for seven days, with subsequent favorable evolution, improvement of the septic condition, and discharge after 22 days of hospitalization. Delivery occurs at 38 weeks, the mother and the newborn evolve in good general condition. The placental histopathological examination demonstrates villous inflammatory involvement, and the newborn's blood tests show the presence of IgG and IgM antibodies. It is one of the few reported cases of transplacental transmission of SARS-CoV-2 from the mother to the newborn.

Increased Circulating Levels of Tissue-Type Plasminogen Activator Are Associated with the Risk of Spontaneous Abortion During the First Trimester of Pregnancy.

Spontaneous abortion is a common complication in early pregnancy, with an incidence of around 20%. Ultrasound scan and measurement of human chorionic gonadotropin are used to identify patients at risk of spontaneous abortion; however, there is a clinical need to find new biomarkers to prospectively identify patients before the onset of clinical symptoms. Here, we aim to investigate potential biomarkers of spontaneous abortion taken in the first clinical appointment of pregnancy. A case-control study was conducted based on a prospectively collected cohort in which cases and controls were retrospectively stratified based on pregnancy outcome: normal healthy pregnancies (controls = 33) and pregnancies that ended in spontaneous abortion (cases = 10). We evaluated extracellular vesicles isolated by precipitation with ExoQuick™ and protein concentrations of tissue plasminogen activator, leptin, and adiponectin measured by ELISA. The extracellular vesicles showed the typical morphology and membrane proteins: CD63, Alix, and Flotilin-1. The size distributions of the isolated extracellular vesicles were 112 ± 27 and 118 ± 28 nm in diameter for controls and spontaneous abortion, respectively, and the total amount of extracellular vesicles did not show any difference between controls and the spontaneous abortion group. The tissue plasminogen activator showed a significant difference (p = 0.0004) between both groups, although neither adiponectin nor leptin revealed significant changes, indicating that women who had spontaneous abortions have significantly higher levels of tissue plasminogen activator than women who had normal pregnancies.

First trimester prediction of gestational diabetes mellitus using plasma biomarkers: a case-control study.

Objectives To evaluate the first trimester maternal biomarkers for early pregnancy prediction of gestational diabetes mellitus (GDM). Methods The study was a case-control study of healthy women with singleton pregnancies at the first trimester carried out at the Obstetrics and Gynecology Unit, Clinica Davila, Santiago, Chile. After obtaining informed consent, peripheral blood samples of pregnant women under 14 weeks of gestation were collected. At 24-28 weeks of pregnancy, women were classified as GDM (n=16) or controls (n=80) based on the results of a 75-g oral glucose tolerance test (OGTT). In all women, we measured concentrations of fasting blood glucose, insulin, glycated hemoglobin, uric acid, cholesterol, high density lipoprotein (HDL), low density lipoprotein (LDL), very low density lipoprotein (VLDL), triglycerides, aspartate aminotransferase (AST), alanine aminotransferase (ALT), γ-glutamyl transpeptidase (GGT), alkaline phosphatase (AP), sex hormone-binding globulin (SHBG), adiponectin, tissue plasminogen activator (t-PA), leptin and placental growth factor (PGF). Results The GDM group displayed an increased median concentration of cholesterol (P=0.04), triglycerides (P=0.003), insulin (P=0.003), t-PA (P=0.0088) and homeostatic model assessment (HOMA) (P=0.003) and an increased mean concentration of LDL (P=0.009) when compared to the control group. The receiver operating characteristic (ROC) curve for significant variables achieved an area under the curve (AUC) of 0.870, a sensitivity of 81.4% and a specificity of 80.0%. The OGTT was positive for GDM according to the IADPSG (International Diabetes in Pregnancy Study Group) criteria. Conclusion Women who subsequently developed GDM showed higher levels of blood-borne biomarkers during the first trimester, compared to women who did not develop GDM. These data warrant validation in a larger cohort.

Ecuaciones alométricas de biomasa aérea para la estimación de los contenidos de carbono en manglares del Caribe Colombiano / Tree above-ground biomass allometries for carbon stocks estimation in the Caribbean mangroves in Colombia

ResumenLa distribución de carbono azul en los ecosistemas, entre los que se cuentan los manglares, es poco conocida en comparación con los grandes avances que existen para los ecosistemas forestales terrestres, a pesar de que su alta productividad y capacidad de almacenamiento de carbono es reconocida. Este estudio, tuvo por objetivo, analizar la biomasa aérea de las especies Rhizophora mangle y Avicennia germinans en el ecosistema de manglar localizado en el área marina protegida denominada Distrito de Manejo Integrado (DMI) Cispatá-Tinajones-La Balsa en el Caribe colombiano. Para ello, con la debida autorización oficial, se cosecharon 30 individuos de cada especie, con el fin de generar modelos alométricos que permitieran estimaciones de biomasa aérea con bajos niveles de incertidumbre. Los resultados indican que la biomasa aérea de los bosques de manglar del Caribe colombiano en el DMI, es de 129.69 ± 20.24 Mg/ha, es decir, que almacenan 64.85 ± 10.12 MgC/ ha. Teniendo en cuenta que el DMI presenta un área de 8 570.9 ha en bosques de manglar, se estima que el carbono total potencialmente almacenado por este ecosistema es de aproximadamente 555 795.93 MgC. Las ecuaciones generadas en este estudio se pueden considerar como una opción alternativa para la evaluación de las reservas de carbono en la biomasa aérea de los bosques de manglar en del Caribe colombiano, dado que otros modelos disponibles para la estimación de la biomasa aérea no discriminan a los bosques de manglar, a pesar de ser ecosistemas particulares. Los modelos pueden ser empleados como una opción para apoyar las estrategias de conservación de bosques y la reducción de emisiones. En general, el potencial de almacenamiento de carbono en los bosques de manglar del Caribe colombiano, es importante, y podría posesionar al país en la conservación de bosques y la reducción de emisiones a través de la conservación del carbono azul almacenado.

AbstractThe distribution of carbon in “Blue Carbon” ecosystems such as mangroves is little known, when compared with the highly known terrestrial forests, despite its particular and recognized high productivity and carbon storage capacity. The objective of this study was to analyze the above ground biomass (AGB) of the species Rhizophora mangle and Avicennia germinans from the Marine Protected Area of Distrito de Manejo Integrado (DMI), Cispatá-Tinajones-La Balsa, Caribbean Colombian coast. With official authorization, we harvested and studied 30 individuals of each species, and built allometric models in order to estimate AGB. Our AGB results indicated that the studied mangrove forests of the DMI Colombian Caribbean was of 129.69 ± 20.24 Mg/ha, equivalent to 64.85 ± 10.12 MgC/ha. The DMI has an area of 8 570.9 ha in mangrove forests, and we estimated that the total carbon potential stored was about 555 795.93 Mg C. The equations generated in this study can be considered as an alternative for the assessment of carbon stocks in AGB of mangrove forests in Colombia; as other available AGB allometric models do not discriminate mangrove forests, despite being particular ecosystems. They can be used for analysis at a more detailed scale and are considered useful to determine the carbon storage potential of mangrove forests, as a country alternative to support forest conservation and emission reduction strategies. In general, the potential of carbon storage from Colombian Caribbean mangrove forests is important and could promote the country leadership of the “blue carbon” stored. Rev. Biol.

Intranasal Administration of Type V Collagen Reduces Lung Carcinogenesis through Increasing Endothelial and Epithelial Apoptosis in a Urethane-Induced Lung Tumor Model.

Type V collagen (Col V) is a "minor" component of normal lung extracellular matrix, which is subjected to decreased and abnormal synthesis in human lung infiltrating adenocarcinoma. We previously reported that a direct link between low amounts of Col V and decreased cell apoptosis may favor cancer cell growth in the mouse lung after chemical carcinogenesis. Moreover, this collagen species was able to trigger DNA fragmentation and impair survival of neoplastic cells. In this study, we have extended our investigation with the aim to obtain further evidence that the death induced by Col V-treatment is of the caspase-9 apoptotic type. We used (1) optical and electron microscopy, (2) quantitation of TUNEL-labeled cells and (3) analysis of the expression levels of Col V and selected genes coding for apoptosis-linked factors, by conventional RT-PCR. BALB/c mice were injected intraperitoneally with 1.5 g/kg body weight of urethane. After urethane injection, the animals received intranasal administration of 20 µg/20 µl of Col V every day during 2 months. We report here that Col V treatment was able to determine significant increase in Col V protein and gene expression and in the percentage of TUNEL-positive cells, to up-regulate caspase-9, resulting in low growth of tumor cells. Our data validate chemical carcinogenesis as a suitable "in vivo" model for further and more detailed studies on the molecular mechanisms of the death response induced by Col V in lung infiltrating adenocarcinoma opening new strategies for treatment.

Correlation between Maternal Characteristics during Early Pregnancy, Fetal Growth Rate and Newborn Weight in Healthy Pregnancies.

BACKGROUND: The objective of this study was to evaluate the association between maternal characteristics in early pregnancy and fetal growth (FG) and birth weight (BW). METHODS: A prospective cohort study was performed in unselected pregnant women who attended an ultrasound evaluation at 11-14 weeks of pregnancy. Medical history, biochemical blood tests, biophysical variables and fetal weight at 20-25 and 30-36 weeks as well as the BW were assessed. Bivariate and multivariate linear models were constructed. RESULTS: In all, 543 patients with normal pregnancy and labor were selected. The multiple regression analysis showed a statistically significant association between maternal body mass index (BMI) in early pregnancy and the uterine artery pulsatility index (UtAPI) in the first trimester with BW (p < 0.0008) and with the ratio of fetal growth between the second and third trimesters (p < 0.0001). No correlation was found between these variables and first trimester levels of hemoglobin or glycemia. CONCLUSION: Maternal first trimester BMI and UtAPI correlate with the rate of intrauterine FG and with the BW. This evidence highlights the influence of maternal first trimester variables on fetuses with normal growth and the potential role of these variables in fetal programming.

Prediction of gestational diabetes early in pregnancy: targeting the long-term complications.

Gestational diabetes (GD), defined as carbohydrate intolerance with onset or first recognition during pregnancy, has a prevalence of 7% and is a growing problem worldwide. Infants born to mothers with GD are more likely to be large for gestational age, incur traumatic birth injury, require a stay in the intensive care unit and develop postnatal metabolic disturbances. As the worldwide epidemic of obesity worsens, more women are entering pregnancy with metabolic alterations and preexisting insulin resistance, which is heightened by the hormonal milieu of pregnancy. The Hyperglycemia Adverse Pregnancy Outcome (HAPO) study has clearly shown that GD-related complications correlate with glycemic control. We will review the current understanding of the physiology of GD and the screening and treatment guidelines that are commonly utilized in clinical care. In addition, we will discuss the need for development of multiparametric models combining maternal clinical risk factors and biomarkers early in pregnancy to better stratify and predict risk of GD-related complications and offer targeted intervention.

Liver transplantation according to Milan criteria an overview of the past ten years / Transplante de fígado de acordo com os critérios de Milão: revisão dos últimos 10 anos

Background: Orthotopic liver transplantation (OLT) remains an excellent treatment approach for HCC in well-selected candidates. Milan Criteria (MC) (a single tumor up to 5cm or up to 3 tumors none larger than 3.0 cm) is the most widely used criteria for selection of those patients. Our aim is to study the current situation of the MC focusing on patient survival and tumor recurrence free rate from 1 to 5-yrs after OLT over the past 10 years. Material and Methods: We have reviewed 59 papers published between2000-2009; from Asia (42.3%), Europe (33.9%) and North America (20.4%). 5.525 patients have undergone OLT within MC. The overall patient survival rate and tumor recurrence free rate from 1 to 5-yrs were analyzed. Results: Overall patient survival rates were 1 year (87.26%), 2 years (81.95%), 3 years (77.47%), 4 years (75.24%) and 5 years (72.41%). We have found tumor recurrence free rate of 80.29% and 71.36% at 1 and 5-yrs, respectively. Conclusion: MC has come to simplify the indication for LT in patients with HCC. The best patient survival rate at 1 and 5 years were in North America (88%) and Asia (76,6%), respectively. On the other hand, Europe had the best tumor recurrence free rate at 5 years (91.8%).

Introdução: O transplante de fígado (TF) continua sendo o melhor tratamento para pacientes, bem selecionados, portadores de carcinoma hepatocelular. Os critérios de Milão (CM) ( tumor único até 5 cm e 3 tumores não maiores que 3 cms) são os critérios mais usados para estes pacientes. Nosso objetivo é avaliar a situação atual dos CM principalmente a sobrevida do paciente e a taxa livre de recorrência tumoral após 1 a 5 anos do TF, nos últimos 10 anos. Material e Métodos: Revisamos 59 trabalhos entre200-2009; da Asia (42,3%), Europa (33,9%) e da América do Norte (20,4%). 5.525 pacientes submeteram-se ao TF com os CM. A sobrevida total dos pacientes e a taxa livre de recorrência tumoral foram analisados. Resultados: A taxa de sobrevida total dos pacientes foi em 1 ano de (87,26%), 2 anos (81,95%), 3 anos (77,47%), 4 anos (75,24%) e 5 anos (72,41%). A taxa livre de recorrência tumoral foi de 80,29% e 71,36% em 1 e 5 anos, respectivamente. Conclusão: A melhor taxa de sobrevida dos pacientes foi na América do Norte (88%) e na Asia (76,6%), respectivamente. Por outro lado, a Europa teve a melhor taxa livre de recorrência de doença em 5 anos (91,8%).
