ABSTRACT 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.

Resumo Pacientes com doença arterial periférica e aterosclerose generalizada apresentam alto risco de complicações cardiovasculares e nos membros, o que afeta sua qualidade de vida e longevidade. A doença aterosclerótica das extremidades inferiores está associada à alta morbimortalidade cardiovascular, sendo necessário para sua adequada terapia realizar o tratamento dos fatores dependentes do paciente, como a modificação no estilo de vida, e dos fatores dependentes do médico, como o tratamento clínico, tratamento endovascular ou cirurgia convencional. A abordagem médica para a doença arterial periférica é multifacetada, e inclui como principais medidas a redução do nível do colesterol, a terapia antitrombótica, o controle da pressão arterial e do diabetes e a cessação do tabagismo. A adesão a esse regime pode reduzir as complicações relacionadas aos membros, como a isquemia crônica que ameaça o membro e pode levar à sua amputação, e as complicações sistêmicas da aterosclerose, como o acidente vascular cerebral e infarto do miocárdio.
Abstract Patients with peripheral artery disease and generalized atherosclerosis are at high risk of cardiovascular and limb complications, affecting both quality of life and longevity. Lower limb atherosclerotic disease is associated with high cardiovascular morbidity and mortality and adequate management is founded on treatments involving patient-dependent factors, such as lifestyle changes, and physician-dependent factors, such as clinical treatment, endovascular treatment, or conventional surgery. Medical management of peripheral artery disease is multifaceted, and its most important elements are reduction of cholesterol level, antithrombotic therapy, control of arterial blood pressure, control of diabetes, and smoking cessation. Adhesion to this regime can reduce complications related to the limbs, such as chronic limb-threatening ischemia, that can result in amputation, and the systemic complications of atherosclerosis, such as stroke and myocardial infarction.

Resumo Objetivo Avaliar aceitação da telemedicina e determinar seus fatores associados em uma clínica de uroginecologia de um hospital público brasileiro. Métodos Trata-se de estudo transversal realizado entre junho e novembro de 2020. Foram recrutadas pacientes que tiveram seus atendimentos eletivos adiados devido à pandemia de doença do coronavírus 2019 (coronavirus disease 2019, COVID-19, em inglês). As variáveis consideradas para a aceitação da telemedicina foram: diagnóstico uroginecológico, idade, escolaridade, local de residência, acesso à internet, tipo de dispositivo, frequência do uso da internet, e uso de plataformas de redes sociais. As variáveis categóricas foras descritas na forma de suas frequências absoluta e relativa. A associação entre essas variáveis foi avaliada por meio do teste exato de Fisher e análises uni e multivariada, e a aceitação da telemedicina foi considerada a variável dependente. Resultados Um total de 225 pacientes foram listadas, e 182 concordaram em participar. A idade média das participantes foi de 59 anos; 81,3% delas tinham acesso à internet, e 87,3% aceitaram a telemedicina. Observaram-se associações estatisticamente significativas entre a aceitação e maior escolaridade (p< 0,01), acesso à internet (p< 0,01), uso diário da internet (p< 0,01), acesso por celular próprio (p< 0,01), e acesso da própria residência (p< 0,01). Nas análises uni e multivariada, somente alto nível de escolaridade esteve associado à aceitação da telemedicina (razão de probabilidades ajustada: 4,82; intervalo de confiança de 95% = 1,59–14,65). Conclusão A maioria das pacientes atendidas em um hospital público de um país em desenvolvimento concordaram com a telemedicina. Acesso à internet e nível de escolaridade foram fatores associados à aceitação da telemedicina nessa população.
Abstract Objective To evaluate the acceptance of telemedicine and determine its associated factors in an urogynecology outpatient clinic of a public hospital in Brazil. Methods The present was a cross-sectional study performed between June and November 2020. The included patients had their elective appointments postponed due to the coronavirus disease 2019 (COVID-19) pandemic. The variables considered regarding the acceptance of telemedicine were: urogynecologic diagnosis, age, level of schooling, place of residence, access to the internet, type of device used, frequency of internet use, and use of social media platforms. The categorical variables were described by their absolute and relative frequencies. The association among variables was evaluated through the Fisher exact test, and univariate and multivariate analyses, considering the acceptance of telemedicine as the dependent variable. Results A total of 225 patients were listed, and 182 agreed to participate. The mean age was 59 years old, 81.3% of the patients had access to the internet, and 87.3% of them accepted telemedicine. There were statistically significant associations regarding the acceptance of telemedicine and high levels of schooling (p< 0.01), internet access (p< 0.01), daily use of the internet (p< 0.01), access through personal mobile phone (p< 0.01), and access through the participant's own residence (p< 0.01). In the univariate and multivariate analyses, only high levels of schooling were associated with the acceptance of telemedicine (Adjusted odds ratio: 4.82; 95% confidence interval = 1.59–14.65). Conclusion Most of the urogynecology patients of a public hospital in a developing country accepted telemedicine. Internet access and level of schooling were the factors associated with the acceptance of telemedicine in urogynecology.

Abstract To analyze the surface topography and mechanical properties of a polyurethane derived from castor oil reinforced with hydroxyapatite (PU–HA) for bone fixation. The surface analysis was performed by Scanning Electron Microscopy (SEM) and the mechanical properties by Vickers microhardness and tensile tests. The SEM images showed that the PU surface presented important characteristics for materials intended for bone fixation, such as an irregular and porous surface. The analysis showed a surface with alternating areas with depressions and elevations of approximately 80±100 µm, presence of pores of 12 µm in size. The microhardness analysis showed values of 0.42±1.01 HV for PU–HA plates, lower in relation to the poly lactic-co-glycolic acid (PLGA) plate (control group). The elastic modulus and ultimate tensile strength of 317.4 MPa, and 35.57 MPa for PLGA sample, 1.187 MPa, and 0.29 MPa for PU–HA sample. The PU produced showed good surface properties, however demands better mechanical properties.

Brazilian Journal of Cardiovascular Surgery
- Journal Metrics
Abstract Introduction: We investigated the clinical course and outcomes of patients submitted to cardiovascular surgery in Brazil and who had developed symptoms/signs of coronavirus disease 2019 (COVID-19) in the perioperative period. Methods: A retrospective multicenter study including 104 patients who were allocated in three groups according to time of positive real time reverse transcriptase-polymerase chain reaction (RT-PCR) for the SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2): group 1, patients who underwent cardiac surgery > 10 days after positive RT-PCR; group 2, patients with a positive RT-PCR within 10 days before or after surgery; group 3, patients who presented positive RT-PCR > 10 days after surgery. The primary outcome was mortality and secondary outcomes were postoperative complications, intensive care unit (ICU) length of stay, and postoperative days of hospitalization. Results: The three groups were similar with respect to age, the European System of Cardiac Operative Risk Evaluation score, and comorbidities, except hypertension. Postoperative complications and death were significantly higher in groups 2 and 3 than in group 1, and no significant difference between groups 2 and 3 was seen. Group 2 showed a high prevalence of surgery performed as an urgent procedure. Although no significant differences were observed in ICU length of stay, total postoperative hospitalization time was significantly higher in group 3 than in groups 1 and 2. Conclusion: COVID-19 affecting the postoperative period of patients who underwent cardiovascular surgery is associated with a higher rate of morbidity and mortality. Delaying procedures in RT-PCR-positive patients may help reduce risks of perioperative complications and death.

Abstract This paper aims to present an analysis of the Quality in Health and Patient Safety Training Program (CQSSP) results of the Sérgio Arouca National School of Public Health. This is a quantitative, qualitative, cross-sectional, and descriptive study based on the Kirkpatrick’s Evaluation Model. The findings provide us with a clearer picture of the success of the CQSSP pedagogical intent through a positive assessment for the Reaction, Learning, Behavioral, Results levels. From the analysis of the perception of the graduates, we observed that 82% of them started to fully consider the occurrence of an error in the provision of care, 68% incorporated the acquired knowledge into their professional practice, and 73% started to study and research themes related to Patient Safety (PS). We also conducted a survey on the number of Patient Safety Centers or equivalent bodies established or reformulated during or after the CQSSP. We also evaluated the extent of the contribution of the course in the implementation of Patient Safety protocols and actions in hospitals. The findings point to a significant contribution of the CQSSP to PS and the quality of hospital care.

Abstract: The AWS A5.1 E6013 electrodes have great interest due to their wide employability. The coatings of these electrodes can alter the results of welding, making it an interesting object of study. An investigation of the chemical composition of the coatings of the electrodes AWS A5.1 E6013 from four Brazilian manufacturers was carried out using dispersive energy X-ray fluorescence spectrometry (DEXRF), scanning electron microscopy (SEM), and mass spectrometry with inductively coupled plasma (ICP-MS). Compounds such as titanium dioxide (TiO2), alkali and alkaline earth metal oxides, and carbonates were observed in the samples, in addition to Al and Si in the form of aluminosilicates. These compounds assist in the extrusion of the coating at the electrode manufacturing stage, increase the basicity of the slag and stabilize the electrical arc formed during welding. The results of the ICP-MS showed that elements such as Co, Cr, Cu, and Ni are added to increase the passivity and the mechanical resistance of the welded joint. Pb residues were observed with levels up to 700 times greater than allowed by national legislation. The presence of these metals in the coatings evidences the need for protective measures when handling the E6013 electrodes.
Resumo: Os eletrodos AWS A5.1 E6013 possuem elevado interesse devido a sua ampla empregabilidade. Os revestimentos destes eletrodos podem alterar os resultados da soldagem, tornando-se um interessante objeto de estudo. Uma investigação da composição química dos revestimentos dos eletrodos AWS A5.1 E6013 de quatro fabricantes brasileiros foi realizada usando espectrometria de fluorescência de raios-X por energia dispersiva (FRXED), microscopia eletrônica de varredura (MEV) e espectrometria de massa com plasma indutivamente acoplado (ICP-MS). Foram observados nas amostras compostos tais como o dióxido de titânio (TiO2), óxidos e carbonatos de metais alcalinos e alcalino-terrosos, além de Al e Si na forma de aluminosilicatos. Estes compostos auxiliam na extrusão do revestimento na etapa de fabricação do eletrodo, elevam a basicidade da escória e estabilizam o arco elétrico formado durante a soldagem. Os resultados do ICP-MS mostraram que elementos como Co, Cr, Cu e Ni são adicionados para aumentar a passividade e a resistência mecânica da junta soldada. Resíduos de Pb foram observados com teores até 700 vezes maior que o permitido pela legislação nacional. As presenças destes metais nos revestimentos evidenciam a necessidade de medidas protetivas ao manipular os eletrodos E6013.

Abstract The (de)hydrogenation properties of a TiFe intermetallic compound (IMC) alloy activated by cold rolling inside a glovebox at ambient temperature were investigated by kinetic measurements, x-ray powder diffraction (XRD), and transmission electron microscopy (TEM). Rate-limiting steps were identified by testing kinetic models on hydrogen absorption and desorption curves. To prevent surface poisoning during air exposure, the TiFe IMC was also cold rolled with polytetrafluoroethylene (PTFE) and ultra-high molecular weight polyethylene (UHMWPE). The addition of either PTFE or UHMWPE to nanostructured TiFe by cold rolling did not produce a polymer-metal composite with O2 poisoning resistance, regardless of the polymer-mixing way adopted. This occurred because large surfaces of the particles were not adequately coated with polymer. The results identify challenges to the TiFe IMC polymer-covered material that must be overcome before a methodology can significantly contribute to the formation of nanostructured TiFe-polymer composites with enhanced hydrogen storage properties. The diffusion-controlled reactions in the cold-rolled TiFe IMC without polymer were prevalent in all cases, as predicted by the Jander three-dimensional diffusion model. The main contribution of this work regards estimation of the amount of hydrogen released, which was 0.60% after 6 min and reproducible for the three subsequent cycles.

Abstract The differential diagnosis of optic neuritis is broad and varied. We report the case of a 24-year-old Brazilian man who presented with five-week history of fever, malaise, myalgia, severe fatigue, tender right preauricular lymphadenopathy, and acute vision blurring associated with right optic disc swelling and exudates in a macular star pattern. His illness developed soon after an infestation of fleas broke out among his cats. Diagnosis of ocular bartonellosis was confirmed by serological and molecular analyses targeting amplification of Bartonella spp. htrA gene. Signs and symptoms only improved after initiation of antimicrobial therapy.

ABSTRACT Zika virus (ZIKV) clinical presentation and frequency/duration of shedding need further clarification. Symptomatic ZIKV-infected individuals identified in two hospitals in Sao Paulo State, Brazil, were investigated regarding clinical characteristics, shedding in body fluids, and serodynamics. Ninety-four of 235 symptomatic patients (Site A: 58%; Site B: 16%) had Real-Time PCR-confirmed ZIKV infection; fever, headache and gastrointestinal symptoms were less frequent, and rash was more frequent compared to ZIKV-negative patients. Real-Time PCR in serum had worse performance compared to plasma, while urine had the highest sensitivity. Shedding in genital fluids and saliva was rare. IgM positivity was the highest <14 days after the symptoms onset (86%), decreasing >28 days (24%); IgG positivity increased >14 days (96%) remaining positive in 94% of patients >28 days. ZIKV prevalence varied importantly in two neighboring cities during the same transmission season. Urine Real-Time PCR can improve diagnostic sensitivity; serum testing is less useful. Accurate serological tests are needed to improve diagnosis and surveillance.

RESUMO: A leptospirose é uma zoonose amplamente distribuída em países tropicais. Essa infecção também está associada a perdas reprodutivas na pecuária, apresentando uma relevância econômica notável. O objetivo deste estudo foi investigar a soroprevalência e os fatores de risco associados à infecção por leptospirose em rebanhos comerciais de ovinos da mesorregião noroeste do Rio Grande do Sul. Amostras de soro de 319 ovelhas foram analisadas pelo Teste de Aglutinação Microscópica (MAT). No momento da amostragem foi realizado um questionário individual e de rebanho para investigar os fatores de risco. No nível individual, reações positivas foram observadas em 5.6% (18/319) dos soros estudados, sendo Sejroe o sorogrupo mais prevalente. Animals >3 years old were more likely to be seropositive than animals 1-3 years old (OR 14.4; 95% CI 1.9-110). A predominância do sorogrupo Sejroe chama a atenção para a infecção subclínica associada a perdas econômicas. Portanto, reitera-se a importância da manutenção de medidas de prevenção e controle da leptospirose entre os rebanhos ovinos da região estudada.
ABSTRACT: Leptospirosis is a zoonosis that is widely distributed in tropical countries. This infection is also associated with reproductive losses in livestock, which has a significant economic impact. The objective of this study is to investigate the seroprevalence and risk factors associated with leptospiral infection in commercial sheep flocks from the northwestern mesoregion of Rio Grande do Sul. Serum samples were analyzed in 319 sheep using the Microscopic Agglutination Test (MAT). At the time of sampling, an individual and herd questionnaire was carried out to investigate the risk factors. On an individual level, positive reactions were observed in 5.6% (18/319) of the studied sera, with Sejroe being the most prevalent serogroup. Animals >3 years old were more likely to be seropositive than animals 1-3 years old (OR 14.4; 95% CI 1.9-110). The predominance of Sejroe serogroup in this manner draws attention to how subclinical infection is associated with economic losses. Therefore, the importance of maintaining measures for the prevention and control of leptospirosis among the sheep flocks of the studied region is reiterated.

Abstract Bone fractures to be corrected need stabilization of their extremities, which is achieved with the use of plates and screws. This research aimed to produce castor bean polyurethane (Ricinus communis), to make resorbable plate, structural and thermal analysis. The production was made by the glycerolysis of the triglycerides present in the oil, after addition of polyol/glycerol and hexamethylene diisocyanate (HDI) to form urethane structures, with and without addition of hydroxyapatite. The characterization was by FTIR spectroscopy, scanning electron microscopy (SEM), X-ray diffraction, differential scanning calorimetry and thermogravimetry. Plates with dimensions of 40 mm X 10 mm X 2 mm were obtained. The SEM showed flat and homogeneous surface. DRX analysis showed the semi-crystallinity of the biomaterial. Glass transition and thermal stability up to 50 °C were observed, followed by thermal decomposition up to 450 °C. The produced polyurethane showed it is possible to be applied in the manufacture of plate.

ABSTRACT Mycobacterium haemophilum is a nontuberculous mycobacterium that causes localized or disseminated disease, mainly in immunocompromised hosts. We report the case of a 35-year-old HIV-infected woman who presented with several enlarging cutaneous lesions over the arms and legs. Histopathological examination revealed the diagnosis of a cutaneous mycobacterial disease. Mycobacterial analyses unveiled M. haemophilum infection. Six months after completion of a successful antimycobacterial treatment, she developed an immune reconstitution inflammatory syndrome (IRIS). This paradoxical relapse presented as tenderness, redness and swelling at the precise sites of the healed lesions and took place in the setting of significant recovery of the CD4 cell count (from 05 to 318 cells/mm 3 ). Microbiological analyses of these worsening lesions were negative, and they spontaneously remitted without the initiation of a novel antimycobacterial treatment cycle. M. haemophilum infection should always be considered as a cause of skin lesions in immunocompromised subjects. Physicians should be aware of the possibility of IRIS as a complication of successful antiretroviral therapy in HIV-infected patients with M. haemophilum infection.
