Prevention and non-pharmacological management of pain in newborns

Objective: to describe the main non-pharmacological interventions for pain relief in newborns available in Neonatal Intensive Care Unit. Method: an exploratory search of the MedLine, Lilacs and Scielo online databases was conducted to retrieve references of studies published from 2004 to 2013. Results: several non-pharmacological interventions were shown to be effective, to represent low risk for neonates and to have a low operational cost. The ones most often discussed in the literature were: oral administration of glucose/sucrose, non-nutritive sucking, breastfeeding, skin-to-skin contact, facilitated tucking and swaddling. Conclusion: healthcare teams should be familiar with these methods and use them more effectively in Neonatal Intensive Care Unit daily routines, so as to ensure that newborns receive qualified and more human care

Late-onset neonatal sepsis in preterm infants with birth weight under 1.500g

Objective: the research objective was to characterize preterm infants with birth weight under 1500 g, and to identify the incidence of late-onset neonatal sepsis among this population. Methods: a prospective cohort study with a sample of 30 preterm newborns that weighed under 1500 g and were hospitalized in the NICU of the university hospital. Data were collected from January to December 2013 using a structured instrument. Results: of the 30 neonates included in the study, 14 developed late-onset neonatal sepsis with a prevalence of coagulase-negative staphylococci. Conclusions: the incidence of late-onset neonatal sepsis indicates a vulnerability in preterm infants due to immunological immaturity. These results reveal that knowledge of the profi le of newborn infants admitted to the NICU and the risk factors to which they are exposed are central to the planning of nursing care for these patients. Future studies should address strategies for preventing nosocomial infection

The microbial culture collections of the Federal University of Pernambuco (UFPE) and the new consortium towards the establishment of BRC-UFPE

The UFPE from Recife in Brazil hosts a bacterial (UFPEDA) and a fungal (URM) collections since 1951 and 1954, respectively. The UFPEDA was established by Prof. Oswaldo Gonçalves de Lima and is register in WDCM as 114. It is hosted at Antibiotic Department (DA) of UFPE and started out with 200 species mainly of the genus Streptomyces. Nowadays this collection holds 4000 strains of actinomycetes isolated from all the Brazilian places and from the International Streptomyces Project (ISP). The URM – University of Recife Mycology was established by Prof. Augusto Chaves Batista and is register in WDCM as 604. Actual it holds 9000 identified species including 1400 yeasts and 7600 filamentous fungi. All major fungal taxonomic groups are cover by this collection. The collections preserve each strain at least by two different techniques. Water and mineral oil storage were used for long operation time while freeze-drying and freezing at -80 ºC become the main techniques used at this stage. Special care is taken to test whether cultures recovered from preserved material conform to the original deposit. These collections have a range of services which are acceptance of free and confidential deposits, supply strains for academia, industry and services, support research and education (graduate and post-graduate students, as well as advanced training courses), identification services and confidential contracts (e.g. fungal medical diagnosis, starters for agro-industry companies, etc.). The OECD initiative related to guidance for the operation of Biological Resource Centres (BRC) is now a key reference for these collections. The right management of biological resources and their associate information including quality control are perused by these collections. The recent national projects, with reasonable budgets to support their activities, either on networking activities or requalification and management create a new breath and responsibilities to these collections. Taking advantage of good and well equipped premises of LIKA these collections are now open new avenues working in consortium to improve the quality control of their holdings using new tools from molecular biology and spectral analysis (MALDI-TOF) to achieve in the future a certified BRC for the UFPE microbial culture collections

Plant productivity enhancement in a simulated Amazonian Dark Earth (Terra Preta Nova).

Amazonian Dark Earths (ADEs) are highly fertile human-made soils, commonly found in Amazonia. These soils have a unique soil biota and a high content of charcoal, organic C, available P and Ca as a result of repeated burning and additions of bone and organic matter (OM) over centuries of Amerindian occupation. ?Terra Preta Nova? techniques aim to replicate these soils by adding ADE components, but little is known of their single and synergistic impacts on plant productivity. We replicated an ADE by adding five distinct components and studying their single and interactive effects on maize production in the greenhouse. Earthworms (Pontoscolex corethrurus), OM (horse manure), biochar (from Brazil nut), ground fish bones and pottery sherds were added to a nutrient poor soil, and after 60 days plant height, above and below-ground (root) biomass, root length, and soil fertility levels were assessed. The main components affecting plant productivity were earthworms, OM and fish bone meal, with significant synergistic effects, while biochar and pottery, although significant, were not as important for plant growth and soil fertility

Cross-cultural adaptation and clinical validation of the neonatal skin condition score to Brazilian Portuguese

Objective: to describe the process of cross-cultural adaptation and clinical validation of the Neonatal Skin Condition Score. Methods: this methodological cross-cultural adaptation study included five steps: initial translation, synthesis of the initial translation, back translation, review by an Committee of Specialists and testing of the pre-final version, and an observational cross-sectional study with analysis of the psychometric properties using the Adjusted Kappa, Intraclass Correlation Coefficient, and Bland- Altman Method statistical tests. A total of 38 professionals were randomly recruited to review the clarity of the adapted instrument, and 47 newborns hospitalized in the Neonatology Unit of the Clinical Hospital of Porto Alegre were selected by convenience for the clinical validation of the instrument. Results: the adapted scale showed approximately 85% clarity. The statistical tests showed moderate to strong intra and interobserver item to item reliability and from strong to very strong in the total score, with a variation of less than 2 points among the scores assigned by the nurses to the patients. Conclusions: the scale was adapted and validated to Brazilian Portuguese. The psychometric properties of the Brazilian version of the Neonatal Skin Condition Score instrument were similar to the validation results of the original scale

Higher education in dark times: from the democratic renewal of Brazilian universities to its current wreck

This article discusses the recent expansion and democratization of Brazil’s higher education system from the beginning of the twentyfirst century to the present, concluding with its contemporary clash with the far-right government, which has placed universities and scientific knowledge under attack – an experience had around the globe. In the last two decades, Brazilian public universities have become more diverse in terms of the class and racial backgrounds of students, as well as their larger expansion with new campuses in the hinterlands, the Amazon, and the peripheries of metropolitan areas. Private higher education has also expanded enormously – in part, thanks to capital concentration, inflow of foreign capital, massive public subsidies and oligopolistic strategies. In both public and private sectors, Brazilian higher education has experienced a renascence. However, since 2018, the new power bloc, concentrated around President Bolsonaro and the far right, chose Public Universities and the National Science and Research system as one of its main targets. The current regressive moment in Brazil it is not an exception, in different countries universities and science are under attack. Ultimately, this article seeks to contribute, not only to a better understanding of Brazil’s on-going experience, but also to the larger public debate on higher education policy in the Global South and other countries facing similar challenges

Genome of the Avirulent Human-Infective Trypanosome—Trypanosoma rangeli

Background: Trypanosoma rangeli is a hemoflagellate protozoan parasite infecting humans and other wild and domestic mammals across Central and South America. It does not cause human disease, but it can be mistaken for the etiologic agent of Chagas disease, Trypanosoma cruzi. We have sequenced the T. rangeli genome to provide new tools for elucidating the distinct and intriguing biology of this species and the key pathways related to interaction with its arthropod and mammalian hosts.  Methodology/Principal Findings: The T. rangeli haploid genome is ,24 Mb in length, and is the smallest and least repetitive trypanosomatid genome sequenced thus far. This parasite genome has shorter subtelomeric sequences compared to those of T. cruzi and T. brucei; displays intraspecific karyotype variability and lacks minichromosomes. Of the predicted 7,613 protein coding sequences, functional annotations could be determined for 2,415, while 5,043 are hypothetical proteins, some with evidence of protein expression. 7,101 genes (93%) are shared with other trypanosomatids that infect humans. An ortholog of the dcl2 gene involved in the T. brucei RNAi pathway was found in T. rangeli, but the RNAi machinery is non-functional since the other genes in this pathway are pseudogenized. T. rangeli is highly susceptible to oxidative stress, a phenotype that may be explained by a smaller number of anti-oxidant defense enzymes and heatshock proteins.  Conclusions/Significance: Phylogenetic comparison of nuclear and mitochondrial genes indicates that T. rangeli and T. cruzi are equidistant from T. brucei. In addition to revealing new aspects of trypanosome co-evolution within the vertebrate and invertebrate hosts, comparative genomic analysis with pathogenic trypanosomatids provides valuable new information that can be further explored with the aim of developing better diagnostic tools and/or therapeutic targets
