Genome-wide identification and characterization of SNW/SKIP domain-containing proteins in plants.

Sessile organisms, such as plants, developed various ways to sense and respond to external and internal stimuli to maximize their fitness through evolutionary time. Transcripts and protein regulation are, among many, the main mechanisms that plants use to respond to environmental changes. SKIP protein is one such, presenting an SNKW interacting domain, which is highly conserved among eukaryotes, where SKI interacting protein acts in regulating key processes. In the present work, many bioinformatics tools, such as phylogenetic relationships, gene structure, physical-chemical properties, conserved motifs, prediction of regulatory cis-elements, chromosomal localization, and protein-protein interaction network, were used to better understand the genome-wide SNW/SKIP domain-containing proteins. In total, 28 proteins containing the SNW/SKIP domain were identified in different plant species, including plants of agronomic interest. Two main protein clusters were formed in phylogenetic analysis, and gene structure analysis revealed that, in general, the coding region had no introns. Also, expression of these genes is possibly induced by abiotic stress stimuli. Primary structure analysis of the proteins revealed the existence of an evolutionarily conserved functional unit. But physicochemical properties show that proteins containing the SNW/SKIP domain are commonly unstable under in vivo conditions. In addition, the protein network, demonstrated that SKIP homologues could act by modulating plant fitness through gene expression regulation at the transcriptional and post-transcriptional levels. This could be corroborated by the expression number of gene copies of SKIP proteins in many species, highlighting it's crucial role in plant development and tolerance through the course of evolution.

Getting knowledge to provide care: prevalence and factors associated with Sexually Transmitted Infections in immigrants from Goiás.

OBJECTIVE: To estimate the prevalence of Sexually Transmitted Infections (STIs) in immigrants and refugees living in the metropolitan region of Goiânia, Goiás. METHOD: This is a cross-sectional and analytical study. Data collection was carried out from July 2019 to January 2020 and 308 immigrants and refugees were included in the sample. All were underwent face-to-face interviews and were tested for HIV, Syphilis, and Hepatitis B, using rapid tests. RESULTS: The general prevalence for any of the STIs investigated was 8.8% (95%CI 6.0% - 12.3%), being 5.8% (95%CI 3.6% - 8.9%) for Hepatitis B, 2.3% for Syphilis (95%CI 1.00% - 4.4%) and 0.7% for HIV (95%CI 0.1% - 2.1%). Multiple analysis, using logistic regression, showed that the variables male gender (OR = 2.7) and length of time living in Brazil (OR = 2.6) were significantly associated with STIs (p < 0.05). CONCLUSION: The results of this study suggest that STIs are a health problem in immigrants/refugees, which appear to be enhanced with the length of migration in the country. Public policies that guarantee health care for this population shall be considered.

Low Vaccine Coverage and Factors Associated with Incomplete Childhood Immunization in Racial/Ethnic Minorities and Rural Groups, Central Brazil.

Discrimination and limited access to healthcare services in remote areas can affect vaccination coverage. Therefore, this study aimed to estimate vaccination coverage for children living in quilombola communities and rural settlements in the central region of Brazil during their first year of life and to analyze the factors associated with incomplete vaccination. An analytical cross-sectional study was conducted on children born between 2015 and 2017. The percentage of children who received all vaccines recommended by the National Immunization Program in Brazil by 11 months and 29 days was used to calculate immunization coverage. Children who received the following vaccines were considered as having a complete basic vaccination schedule: one dose of BCG; three doses of Hepatitis B, of Diphtheria-Tetanus-Pertussis (DPT), of Haemophilus influenzae type b (Hib), and of Poliovirus (Polio); two doses of Rotavirus, of 10-valent pneumococcal (PCV10), and of Serogroup C meningococcal conjugate (MenC); and one dose of Yellow Fever (YF). Measles-mumps-rubella (MMR) and other doses recommended at or after 12 months were not included. Consolidated logistic regression was used to identify factors associated with incomplete vaccination coverage. Overall vaccination coverage was 52.8% (95% CI: 45.5-59.9%) and ranged from 70.4% for the Yellow Fever vaccine to 78.3% for the Rotavirus vaccine, with no significant differences between the quilombola and settler groups. Notably, the likelihood of incomplete general vaccination coverage was higher among children who did not receive a visit from a healthcare professional. Urgent strategies are required to achieve and ensure health equity for this unique and traditionally distinct group with low vaccination coverage.

Prevalence, Risk Factors and Vaccine Response against Hepatitis B in People Aged 50 Years or Older.

Universal immunization against hepatitis B has contributed to reducing incidence of the disease, but older individuals remain susceptible to acquiring the hepatitis B virus worldwide. Thus, this study aimed to investigate the epidemiology of HBV infection in individuals aged 50 years and over in central Brazil and to evaluate the immunogenicity of the monovalent vaccine against hepatitis B in this age group using two vaccine regimens. METHOD: Initially, a cross-sectional and analytical study was carried out to investigate the epidemiology of hepatitis B. Then, individuals without proof of vaccination for hepatitis B were recruited for a phase IV randomized and controlled clinical trial using two vaccine regimens: Intervention Regimen (IR) (three doses of 40 µg at months 0, 1 and 6) vs. Comparison Regimen (CR) (three doses of 20 µg at months 0, 1 and 6). RESULTS: The overall prevalence of exposure to HBV was 16.6% (95% CI: 14.0%-9.5%). In the clinical trial, statistical differences in protective titers were observed (p = 0.007; IR 96% vs. CR 86%) and the geometric mean of anti-HBs titers was higher in individuals who received the IR (518.2 mIU/mL vs. 260.2 mIU/mL). In addition, the proportion of high responders was higher among those who received the IR (65.3%). CONCLUSION: reinforced doses should be used in individuals aged 50 years or older to overcome the lower efficacy of the vaccine against hepatitis B.

ABSTRACT Objective: To describe management practices of insulin provided by the SUS and analyze the factors associated with insulin management mistakes. Method: Cross-sectional study addressing 113 individuals with Diabetes Mellitus from an outpatient clinic in Goiânia, GO, Brazil. Data concerning insulin storage, preparation, and administration were collected from the patients' medical records and classified as appropriate or inappropriate. Results: 58.4% of participants were women aged 48 years old on average. Hypertension was reported by 70.8%, and glycated hemoglobin was ≥7% in 89.0%. All the patients made at least one insulin management mistake, and 62.8% made four or more mistakes. The most frequent mistakes were: storing insulin in non-recommended places (46.7%), not injecting insulin 30 minutes before meals (87.5%), not checking for the presence of lumps in the NPH insulin vial (71.9%), and not removing the insulin from the refrigerator between 15 and 30 minutes before injection (88.7%). No significant statistical differences were found among the exposure variables, though women, young individuals, those with 11 or more years of schooling, having the disease for more than ten years, and injecting insulin once or twice a day, more frequently made four or more management mistakes. Conclusion: A high prevalence of insulin management mistakes and considerable variability of practices were identified, reinforcing the importance of implementing a DM line of care at all healthcare system levels.

Medical data set classification using a new feature selection algorithm combined with twin-bounded support vector machine.

Early diagnosis and treatment are the most important strategies to prevent deaths from several diseases. In this regard, data mining and machine learning techniques have been useful tools to help minimize errors and to provide useful information for diagnosis. Our paper aims to present a new feature selection algorithm. In order to validate our study, we used eight benchmark data sets which are commonly used among researchers who developed machine learning methods for medical data classification. The experiment has shown that the performance of our proposed new feature selection method combined with twin-bounded support vector machine (FSTBSVM) is very efficient. The robustness of the FSTBSVM is examined using classification accuracy, analysis of sensitivity, and specificity. The proposed FSTBSVM is a very promising technique for classification, and the results show that the proposed method is capable of producing good results with fewer features than the original data sets. Graphical abstract Model using a new feature selection and grid search with 10-fold CV to optimize model parameters in our FSTBSVM.

Falla hepática fulminante por virus Epstein Barr: rol de los corticoides: caso clínico / Epstein Barr virus and acute liver failure: role of steroids: clinical case

La falla hepática fulminante (FHF) debida a Virus Epstein Barr (VEB) es poco frecuente en inmunocompetentes. La utilidad de los esteroides en este cuadro no ha sido definida y permanece muy controversial. Objetivo: Reportar el caso de una paciente con mononucleosis infecciosa por VEB que presenta FHF y es tratada con corticoides. Caso clínico: Escolar con cuadro de 2 sem de síntomas respiratorios altos, fiebre, adenopatías, con ictericia y orina oscura. Bilirrubina total: 9; B. Directa: 6,3; Fosfatasas Alcalinas: 523; GOT: 7.527; GPT: 6.537; Protrombina (PT): 17 por ciento INR: 4,7; Amonio 510 y glicemia 33. Ecografía abdominal hígado normal y esplenomegalia. Monotest Positivo. Se transfirió a centro de trasplante hepático (TH). Laboratorio de ingreso PT 21 por ciento; bilirrubina en 9,8; GOT 2717; GPT 3716 y amonio 177. EEG con enlentecimiento difuso compatible con encefalopatía grado 1. IgM VEB positiva, descartándose otras etiologías. Se activó para TH por FHF y mientras se administró Metilprednisolona por 5 días. Evolucionó con normalización de las pruebas hepáticas y mejoría clínica. Conclusión: En este caso el uso de esteroides se asoció a una rápida y favorable respuesta tanto clínica como de laboratorio sin presentar efectos secundarios negativos. Al igual que en otras presentaciones de infección grave por VEB, debiera considerarse el uso de esteroides en FHF por VEB.

Acute liver failure (ALF) due to Epstein Barr Virus (EBV) is rare in immunocompetent patients. The role of steroids in this case is not well defined and remains controversial. Case report: 7 years old female presenting with unspecific respiratory symptoms for 2 weeks, fever, lymphadenopathy, jaundice and dark brown urine. Total bilirubin: 9 and direct: 6.3, alkaline phosphatases: 523; AST: 7.527, ALT: 6.537; Prothrombin (PT): 17 percent, INR: 4.7; ammonium 510 and glucose 33. Abdominal ultrasound: normal liver and splenomegaly. Monotest Positive. She was transferred to a liver transplant centre (LT). Lab results at admission: PT 21 percent, bilirubin 9.8, AST 2717, ALT 3.716 and ammonium 177. EEG with diffuse and slowing conductivity consistent with encephalopathy. Positive IgM EBV, other aetiologies were ruled out. She was activated for LT due to ALF and while in waiting list methylprednisolone was administered for 5 days. She evolved with normalization of liver tests and clinical improvement. Conclusion: In this case the use of steroids was associated with a rapid and favourable clinical and laboratory response without negative side effects. As in other presentations of serious infection by EBV, should consider the use of steroids in ALF due to EBV.

A formação ético-humanista do enfermeiro: um olhar para os projetos pedagógicos dos cursos de graduação em enfermagem de Goiânia, Brasil / The ethical-humanistic education of nurses: analyzing the pedagogic projects of the nursing courses in Goiânia (GO, Brazil) / La formación ético-humanista del enfermero: una mirada a los proyectos pedagógicos de los cursos de enfermería en Goiania/GO, Brasil

Trata-se de estudo de abordagem qualitativa, com delineamento de pesquisa documental, cujo objetivo é identificar e descrever a inserção do referencial ético-humanista nos projetos pedagógicos dos cursos de graduação em Enfermagem de Goiânia, Brasil. A investigação foi desenvolvida em cinco instituições de Ensino Superior por meio da análise dos referidos projetos, nos quais buscamos termos que faziam referência à abordagem ético-humanista, gerando duas categorias: "A formação do profissional ético-humanista" e "O enfoque da integralidade no contexto dos projetos pedagógicos dos cursos". Das 218 ementas analisadas, em apenas quarenta encontramos algum termo relacionado ao referencial estudado. A análise detalhada desses documentos permitiu identificar, em toda a sua extensão, aspectos teórico-filosóficos relevantes desse referencial. O estudo apresenta elementos que poderão promover reflexões, fazendo com que os princípios do referencial ético-humanista sejam efetivamente norteadores da reforma curricular de acordo com a atual legislação educacional brasileira.

This qualitative study with a documentary research design aims to identify and describe the inclusion of the ethical-humanistic framework in the Pedagogic Projects of the Courses (PPC) of Nursing in the city of Goiânia, state of Goiás. The research was developed in five Higher Education Institutions through the study of the PPC, in which we searched for terms that referred to the ethical-humanistic approach. Two categories were generated: "The education of the ethical-humanistic professional" and "The focus of integrality in the PPC context." Among 218 analyzed syllabuses, only in forty of them did we find some term related to the studied framework. Despite the limited number of selected syllabuses, the detailed analysis of the documents allowed to identify, in all their extent, relevant theoreticalphilosophic aspects of this framework. Thus, the research presents elements that can promote reflections, making the principles of the ethical-humanistic framework effectively guide the curriculum reform in accordance with the current Brazilian educational legislation.

[Pulmonary hypertension in pediatric and neonatal intensive care unit. Part II: diagnosis and treatment]. / Hypertension pulmonaire de l'enfant et du nouveau-né en réanimation. Partie II : diagnostic et traitement.

In pediatric and neonate intensive care units, the most common causes of pulmonary hypertension (PHT) are congenital cardiac malformations, whether operated or not, respiratory diseases leading to acute or chronic hypoxemia, and left heart failure. In children and neonates, ultrasound is now the reference exam to detect and/or diagnose a PHT. Most often, the changes in morphology of the right ventricle and/or septal kinetics provide the diagnosis; the presence of valvular regurgitation (tricuspid, pulmonary) as well as cardiac or extrapulmonary shunts enables quantifying pulmonary arterial pressures with the Doppler flow. Monitoring the factors favoring PHT (hypoxemia, acidosis, hypercapnia, stress, etc.), oxygenation, ventilation, and systemic hemodynamics is crucial before planning specific treatment. Nitric oxide is the first treatment attempted in the ICU; other treatments (prostacyclin, sildenafil, bosentan) can be used in severe PHT, but cautiously because their usefulness in children has only been suggested in small case series.

[Pulmonary hypertension in pediatric and neonatal intensive care unit. Part I: Physiopathology]. / Hypertension pulmonaire de l'enfant et du nouveau-né en réanimation. Partie I : physiopathologie.

Pulmonary hypertension may be encountered in the pediatric and neonatal intensive care unit. Managing these patients in the intensive care unit can prove extremely challenging, particularly when they become hemodynamically unstable. Pulmonary hypertension in pediatric patients is frequently associated with critical illnesses such as congenital heart disease, acute respiratory disease, and left heart failure. In neonates, pulmonary hypertension is idiopathic or related to respiratory distress or congenital heart failure. This review discusses the pathogenesis and physiology of pulmonary hypertension, the cardiopulmonary interactions in this pathology, and the adaptation to extra-uterine life.

Uso racional de corticoides en el paciente con shock séptico / Rational use of corticoids in a patient with septic shock

Introduction: Septic shock (SS) is a significant cause of mortality in NICUs. Objective: Review current knowledge on Hypothalamic-Pituitary-Adrenal Axis (HPA) and the scientific support for the use of gluco-corticoids in the use of this clinical picture. We know that the patient's ability to evolve into improvement or worsening depends upon the ability of the HPA axis to develop and sustain an adequate response to the stress provoked by SS. In some patients, due to many reasons, the prolongation of SS leads to a deficit of cortisol those results in functional acute adrenal insufficiency. Cortisol levels do not respond to ACTH stimulation test. There is no consensus among authors as to what is a normal concentration of cortisol during stress, or even if it is correlated with death among children with SS. The American College of Critical Care Medicine guidelines for SS in Pediatrics and Neonatology have made some recommendations for use of hydrocortisone.

Introducción: El shock séptico (SS) es una de las mayores causas de mortalidad en unidades de cuidados intensivos pediátricas. Objetivo: Revisar qué sabemos hasta ahora del papel que juega el eje hipotálamo-pituitaria-adrenal (HPA) en el SS y si hay evidencia científica que apoye el uso de glucocorticoides en el transcurso de este cuadro. Sabemos que de la habilidad del eje HPA para montar y sostener en el tiempo una adecuada respuesta al stress provocado por un SS dependerá si el paciente evoluciona a la mejoría o se agrava. En algunos pacientes debido a múltiples mecanismos, la prolongación del SS puede llevar a un déficit de cortisol, resultando en una insuficiencia adrenal aguda o funcional, la que se reflejaría en que los niveles de cortisol no responderían con un incremento significativo frente a una prueba de estimulo con ACTH. Entre los diversos reportes revisados, no existe consenso sobre cual sería la concentración "normal" de cortisol durante el stress y más aun no está claro si esto se correlacionaría con la mortalidad en el caso de los niños. Las guías de shock séptico en pediatría y neonatología del American College of Critical Care Medicine recomiendan en que tipo de pacientes con SS se debiera considerar tratamiento con hidrocortisona.

Protective role of the antidiabetic drug metformin against chronic experimental pulmonary hypertension.

BACKGROUND AND PURPOSE: Pulmonary arterial hypertension (PAH) is associated with increased contraction and proliferation of pulmonary vascular smooth muscle cells. The anti-diabetic drug metformin has been shown to have relaxant and anti-proliferation properties. We thus examined the effect of metformin in PAH. EXPERIMENTAL APPROACH: Metformin effects were analysed in hypoxia- and monocrotaline-induced PAH in rats. Ex vivo and in vitro analyses were performed in lungs, pulmonary artery rings and cells. KEY RESULTS: In hypoxia- and monocrotaline-induced PAH, the changes in mean pulmonary arterial pressure and right heart hypertrophy were nearly normalized by metformin treatment (100 mg.kg(-1).day(-1)). Pulmonary arterial remodelling occurring in both experimental models of PAH was also inhibited by metformin treatment. In rats with monocrotaline-induced PAH, treatment with metformin significantly increased survival. Metformin increased endothelial nitric oxide synthase phosphorylation and decreased Rho kinase activity in pulmonary artery from rats with PAH. These effects are associated with an improvement of carbachol-induced relaxation and reduction of phenylephrine-induced contraction of pulmonary artery. In addition, metformin inhibited mitogen-activated protein kinase activation and strongly reduced pulmonary arterial cell proliferation during PAH. In vitro, metformin directly inhibited pulmonary artery smooth muscle cell growth. CONCLUSIONS AND IMPLICATIONS: Metformin protected against PAH, regardless of the initiating stimulus. This protective effect may be related to its anti-remodelling property involving improvement of endothelial function, vasodilatory and anti-proliferative actions. As metformin is currently prescribed to treat diabetic patients, assessment of its use as a therapy against PAH in humans should be easier.

Falla hepática fulminante en niños / Acute liver failure in children: experience of a liver transplant center

Background: Acute liver failure (ALF) in childhood is defined as biochemical evidence of liver injury, absence of known chronic liver disease and coagulopathy not corrected by vitamin K administration, with INR greater than 1.5 if the patient has encephalopathy or greater than 2.0 if the patient does not have encephalopathy. Objective: Report the experience of a single liver transplant center (LT) in the treatment of 8 children with ALF and review the literature. Method: Retrospective review of clinical charts of patients with ALF. Results: The median age was 8 years-old (range 0-11), three females. Five patients underwent LT. Two patients died, one of them LT. The etiologies were 4 undetermined, 1 autoimmune, 1 Wilson Disease, 1 Parvo virus and 1 chronic graft rejection. All grafts were from cadaver donor, 3 of them reduced. Two out of five patients with encephalopathy grade III-IV died. The one year survival rate was 75 percent. Conclusions: Children with ALF should be treated in experienced centers with facilities for liver transplant. Transplantation should be offered only if the underlying disease is treatable by liver replacement and if transplant prognosis is better than that of the underlying disease.

Falla hepática fulminante (FHF) en la infancia se define como evidencia bioquímica de daño hepático, sin antecedentes conocidos de enfermedad hepática crónica, coagulopatía no corregida por la administración de vitamina K e INR superior a 1,5 si el paciente tiene encefalopatía o superior a 2 si no tiene encefalopatía. Objetivo: Presentar la experiencia de un centro de trasplante hepático (TH) en el tratamiento de 8 niños con FHF y revisar la literatura. Pacientes y Método: Revisión retrospectiva de la historia clínica de pacientes con FHF. Resultados: La edad media fue de 8 años, rango 0-11, tres sexo femenino. Cinco pacientes fueron sometidos a TH. Dos pacientes fallecieron, uno de ellos con TH. La etiología fue indeterminada en 4 pacientes, 1 autoinmune, 1 enfermedad de Wilson, 1 parvovirus y 1 rechazo crónico del injerto. Todos los injertos fueron de donante cadáver, 3 de ellos reducidos. Dos de cinco pacientes con encefalopatía grado III-IV fallecieron. La tasa de sobrevida al año fue de 75 por ciento. Conclusión: El manejo de la FHF debe realizarse en un centro con capacidad de realizar TH, aunque no todos los pacientes requerirán finalmente esta terapia. El TH debiera ser ofrecido sólo si la enfermedad subyacente es tratable con reemplazo hepático y si el pronóstico del TH es mejor que el de la enfermedad misma.
