Psychological and psychiatric aspects of bone marrow transplantation
A intensidade e a complexidade envolvidas no transplante de medula óssea (TMO), em seus vários níveis, produz profundos efeitos psicológicos no paciente, na família e na equipe profissional. Ignorar esta realidade e reduzir os problemas do TMO a seus aspectos puramente técnicos pode trazer consequências catastróficas para o paciente e seus familiares e ameaçar a sobrevivência da equipe. Neste trabalho, são discutidos três aspectos muito importantes de saúde mental no TMO, enfatizando a prática desenvolvida na Unidade de TMO do HCFMRP: 1) os múltiplos papéis desempenhados pela assistência psiquiátrica na Unidade de TMO, desde a prescrição de psicofármacos até o apoio à equipe multiprofissional em grupos de reflexão; 2) uma análise dos sentimentos vivenciados pelo paciente submetido ao TMO nas diferentes fases do transplante (pré, intra e pós-TMO) sob a perspectiva da esperança de cura; 3) uma avaliação da qualidade de vida dos pacientes submetidos ao TMO, a curto e médio prazos, integrando vários instrumentos de análise, incluindo técnicas projetivas.The intensity and complexity involved in all levels of bone marrow transplantation (BMT) causes profound psychological effects on the patient, family and professional team. Ignoring this fact and reducing BMT issues to purely technical aspects may be catastrophical to the patients and his/her family and may challenge the survival of the program. In this work, three very important aspects of mental health in BMT are discussed: 1) multiple roles played by psychiatric assistance in BMT, from drug prescription through support of the team by group reflexion; 2) an analysis of emotions experienced by BMT patients in the different phases of transplantation (pre, intra- and post-) under the perspective of hope for cure ; 3) an evaluation of quality of life of patients submitted to BMT at medium and long terms, integrating various psychological instruments including projective techniques
ATLANTIC-PRIMATES: a dataset of communities and occurrences of primates in the Atlantic Forests of South America
Primates play an important role in ecosystem functioning and offer critical insights into human evolution, biology, behavior, and emerging infectious diseases. There are 26 primate species in the Atlantic Forests of South America, 19 of them endemic. We compiled a dataset of 5,472 georeferenced locations of 26 native and 1 introduced primate species, as hybrids in the genera Callithrix and Alouatta. The dataset includes 700 primate communities, 8,121 single species occurrences and 714 estimates of primate population sizes, covering most natural forest types of the tropical and subtropical Atlantic Forest of Brazil, Paraguay and Argentina and some other biomes. On average, primate communities of the Atlantic Forest harbor 2 ± 1 species (range = 1–6). However, about 40% of primate communities contain only one species. Alouatta guariba (N = 2,188 records) and Sapajus nigritus (N = 1,127) were the species with the most records. Callicebus barbarabrownae (N = 35), Leontopithecus caissara (N = 38), and Sapajus libidinosus (N = 41) were the species with the least records. Recorded primate densities varied from 0.004 individuals/km 2 (Alouatta guariba at Fragmento do Bugre, Paraná, Brazil) to 400 individuals/km 2 (Alouatta caraya in Santiago, Rio Grande do Sul, Brazil). Our dataset reflects disparity between the numerous primate census conducted in the Atlantic Forest, in contrast to the scarcity of estimates of population sizes and densities. With these data, researchers can develop different macroecological and regional level studies, focusing on communities, populations, species co-occurrence and distribution patterns. Moreover, the data can also be used to assess the consequences of fragmentation, defaunation, and disease outbreaks on different ecological processes, such as trophic cascades, species invasion or extinction, and community dynamics.

We also request that researchers and teachers inform us of how they are using the data. © 2018 by the The Authors. Ecology © 2018 The Ecological Society of Americ
Catálogo Taxonômico da Fauna do Brasil: setting the baseline knowledge on the animal diversity in Brazil
The limited temporal completeness and taxonomic accuracy of species lists, made available in a traditional manner in scientific publications, has always represented a problem. These lists are invariably limited to a few taxonomic groups and do not represent up-to-date knowledge of all species and classifications. In this context, the Brazilian megadiverse fauna is no exception, and the Catálogo Taxonômico da Fauna do Brasil (CTFB) (http://fauna.jbrj.gov.br/), made public in 2015, represents a database on biodiversity anchored on a list of valid and expertly recognized scientific names of animals in Brazil. The CTFB is updated in near real time by a team of more than 800 specialists. By January 1, 2024, the CTFB compiled 133,691 nominal species, with 125,138 that were considered valid. Most of the valid species were arthropods (82.3%, with more than 102,000 species) and chordates (7.69%, with over 11,000 species). These taxa were followed by a cluster composed of Mollusca (3,567 species), Platyhelminthes (2,292 species), Annelida (1,833 species), and Nematoda (1,447 species). All remaining groups had less than 1,000 species reported in Brazil, with Cnidaria (831 species), Porifera (628 species), Rotifera (606 species), and Bryozoa (520 species) representing those with more than 500 species. Analysis of the CTFB database can facilitate and direct efforts towards the discovery of new species in Brazil, but it is also fundamental in providing the best available list of valid nominal species to users, including those in science, health, conservation efforts, and any initiative involving animals. The importance of the CTFB is evidenced by the elevated number of citations in the scientific literature in diverse areas of biology, law, anthropology, education, forensic science, and veterinary science, among others
Mortality from gastrointestinal congenital anomalies at 264 hospitals in 74 low-income, middle-income, and high-income countries: a multicentre, international, prospective cohort study
Summary
Background Congenital anomalies are the fifth leading cause of mortality in children younger than 5 years globally.
Many gastrointestinal congenital anomalies are fatal without timely access to neonatal surgical care, but few studies
have been done on these conditions in low-income and middle-income countries (LMICs). We compared outcomes of
the seven most common gastrointestinal congenital anomalies in low-income, middle-income, and high-income
countries globally, and identified factors associated with mortality.
Methods We did a multicentre, international prospective cohort study of patients younger than 16 years, presenting to
hospital for the first time with oesophageal atresia, congenital diaphragmatic hernia, intestinal atresia, gastroschisis,
exomphalos, anorectal malformation, and Hirschsprung’s disease. Recruitment was of consecutive patients for a
minimum of 1 month between October, 2018, and April, 2019. We collected data on patient demographics, clinical
status, interventions, and outcomes using the REDCap platform. Patients were followed up for 30 days after primary
intervention, or 30 days after admission if they did not receive an intervention. The primary outcome was all-cause,
in-hospital mortality for all conditions combined and each condition individually, stratified by country income status.
We did a complete case analysis.
Findings We included 3849 patients with 3975 study conditions (560 with oesophageal atresia, 448 with congenital
diaphragmatic hernia, 681 with intestinal atresia, 453 with gastroschisis, 325 with exomphalos, 991 with anorectal
malformation, and 517 with Hirschsprung’s disease) from 264 hospitals (89 in high-income countries, 166 in middleincome
countries, and nine in low-income countries) in 74 countries. Of the 3849 patients, 2231 (58·0%) were male.
Median gestational age at birth was 38 weeks (IQR 36–39) and median bodyweight at presentation was 2·8 kg (2·3–3·3).
Mortality among all patients was 37 (39·8%) of 93 in low-income countries, 583 (20·4%) of 2860 in middle-income
countries, and 50 (5·6%) of 896 in high-income countries (p<0·0001 between all country income groups).
Gastroschisis had the greatest difference in mortality between country income strata (nine [90·0%] of ten in lowincome
countries, 97 [31·9%] of 304 in middle-income countries, and two [1·4%] of 139 in high-income countries;
p≤0·0001 between all country income groups). Factors significantly associated with higher mortality for all patients
combined included country income status (low-income vs high-income countries, risk ratio 2·78 [95% CI 1·88–4·11],
p<0·0001; middle-income vs high-income countries, 2·11 [1·59–2·79], p<0·0001), sepsis at presentation (1·20
[1·04–1·40], p=0·016), higher American Society of Anesthesiologists (ASA) score at primary intervention
(ASA 4–5 vs ASA 1–2, 1·82 [1·40–2·35], p<0·0001; ASA 3 vs ASA 1–2, 1·58, [1·30–1·92], p<0·0001]), surgical safety
checklist not used (1·39 [1·02–1·90], p=0·035), and ventilation or parenteral nutrition unavailable when needed
(ventilation 1·96, [1·41–2·71], p=0·0001; parenteral nutrition 1·35, [1·05–1·74], p=0·018). Administration of
parenteral nutrition (0·61, [0·47–0·79], p=0·0002) and use of a peripherally inserted central catheter (0·65
[0·50–0·86], p=0·0024) or percutaneous central line (0·69 [0·48–1·00], p=0·049) were associated with lower mortality.
Interpretation Unacceptable differences in mortality exist for gastrointestinal congenital anomalies between lowincome,
middle-income, and high-income countries. Improving access to quality neonatal surgical care in LMICs will
be vital to achieve Sustainable Development Goal 3.2 of ending preventable deaths in neonates and children younger
than 5 years by 2030
Seed-specific stable expression of the alpha-AI1 inhibitor in coffee grains and the in vivo implications for the development of the coffee berry borer
Genetic transformation of coffee (Coffea spp.), the second most traded commodity worldwide, is an alternative approach to introducing features that cannot be introgressed by traditional crossings. The transgenic stability, heritability and quantitative and spatial expression patterns of the seed-specific promoter phytohemagglutinin (PHA-L) from Phaseolus vulgaris were characterized in genetically modified C. arabica expressing the alpha-amylase inhibitor-1 (alpha-AI1) gene. The alpha-AI1 inhibitor shows considerable activity toward digestive enzymes of the coffee berry borer (CBB) Hypothenemus hampei. This insect pest expends its life cycle almost entirely in coffee berries. Transgene containment in the fruit is important to meeting food and environmental safety requirements for releasing genetically modified (GM) crops. PCR analysis of T2 coffee plants showed a Mendelian single-copy segregation pattern. Ectopic transgene expression was only detected in coffee grains, as demonstrated by reverse transcription-PCR analysis of different plant tissues. An intense immunocytochemical signal associated with alpha-AI1 protein expression was localized to endospermic cells. In addition, a delay in the larval development of CBB was observed after challenging transgenic coffee seeds with the insect. These results indicate that the PHA-L promoter might be a useful tool in coffee for the seed-specific expression of genes related to coffee bean productivity, quality and pest protection. The biotechnological applicability of the alpha-AI1 gene for controlling CBB is also discussed. This work is the first report showing a seed-specific transgene expression in coffee plants
Degloving médio-facial como via de acesso a tumores nasossinusais Midfacial degloving - acess to nasal cavity and paranasal sinuses lesions
Abordagens cirúrgicas comuns para maxilectomia medial incluem a rinotomia lateral e a via de acesso degloving médio-facial. A rinotomia lateral fornece um excelente campo cirúrgico, mas deixa proeminentes cicatrizes na face. Já o degloving médio-facial tem sido superior à rinotomia lateral, pois não deixa nenhuma cicatriz externa, embora saibamos que este procedimento tem suas limitações¹. Este estudo tem o objetivo de descrever os resultados estéticos e de melhor acesso transoperatório de cirurgias nasossinusais via degloving, com avaliação da morbidade pós-operatória através das seguintes variáveis: hemoglobina pré e pós-operatória, necessidade de transfusão sangüínea, presença de complicações, uso de tampão nasal, uso de antibiótico, fio cirúrgico utilizado, tempo de internamento pós-operatório e presença de recidiva. Foi realizado um estudo retrospectivo a partir de 16 pacientes internados no Hospital Geral de Fortaleza SESA/SUS durante o período de dezembro de 1999 a novembro de 2003. Pelos dados obtidos, conclui-se que a via de acesso degloving é eficaz no tratamento de lesões nasossinusais extensas, com bons resultados estéticos e com reduzida morbidade pós-operatória.<br>Common surgical approaches for medial maxillectomy include lateral rhinotomy and midfacial degloving. Lateral rhinotomy provides excellent surgical exposure but leaves a bulging scar on the face. Despite its own limitations, midfacial degloving has been preferred to lateral rhinotomy because it does not leave any external scar on the face¹. The aim of this study is to evaluate the cosmetic results and surgical exposure access of midfacial degloving. Treatment morbidity was evaluated through: post operative hospital stay length, blood transfusion needs, complications, pre and post operative hemoglobin levels, disease recurrence, nasal packing, type of suture and antibiotics. Retrospective study was carried out with sixteen patients treated at the Hospital Geral de Fortaleza SESA/SUS from December 1999 through November 2003. Based on the results, we may conclude that midfacial degloving is effective to treat extensive nasal cavity lesions and paranasal sinuses with reduced post operative morbidity
