The publication Cardiovascular Statistics – Brazil aims to provide an annual compilation of data and research on the epidemiology of CVDs in Brazil. The report integrates official statistics from the Brazilian Ministry of Health and other governmental entities alongside data from the GBD project, coordinated by the IHME at the University of Washington. Additionally, it incorporates data derived from various sources and scientific studies, including cohorts and registries, that relate to CVDs and their associated risk factors. This publication is intended for a wide range of individuals, including researchers, clinicians, patients, healthcare policymakers, media professionals, the general public, and other interested parties seeking extensive national data about heart disease and stroke. Volunteer researchers from various Brazilian universities and research institutions carry out the project. The group is led by a five-member steering committee (ALPR, CAP, DCM, GMMO, and LCCB). The Brazilian Society of Cardiology fully supports this initiative, and the project receives collaborative support from the GBD Brazil Network and an International Committee (GAR, PP, and TAG) from both the IHME/University of Washington (GAR) and the World Heart Federation (PP and TAG).

RESUMO Objetivo: Comparar a morbidade em 90 dias de pacientes submetidos à lobectomia pulmonar por robotic-assisted thoracic surgery (RATS, cirurgia torácica robótica) ou por video-assisted thoracic surgery (VATS, cirurgia torácica videoassistida). Complicações intraoperatórias, tempo de drenagem, tempo de internação hospitalar, dor pós-operatória, qualidade de vida pós-operatória e reinternações em 90 dias também foram comparados. Métodos: Ensaio clínico randomizado, com dois braços, incluindo pacientes com lesões pulmonares (câncer de pulmão primário ou metástase pulmonar) candidatos à lobectomia pulmonar. Foram excluídos pacientes com comorbidades que impossibilitassem o tratamento cirúrgico. Todos os pacientes seguiram o mesmo protocolo pós-operatório. Resultados: A amostra total foi composta por 76 pacientes (39 no grupo VATS e 37 no grupo RATS). Os dois grupos foram semelhantes quanto a sexo, idade, IMC, VEF1 em % do previsto e comorbidades. Complicações pós-operatórias em 90 dias tenderam a ser mais frequentes no grupo VATS do que no grupo RATS, mas a diferença não foi significativa (p = 0,12). No entanto, quando analisadas apenas as complicações maiores, essa tendência desapareceu (p = 0,58). Quanto aos desfechos pós-operatórios, o grupo VATS apresentou um número significativamente maior de reinternações em 90 dias do que o grupo RATS (p = 0,029). Não foram encontradas diferenças significativas quanto a complicações intraoperatórias, tempo de drenagem, tempo de internação hospitalar, dor pós-operatória e qualidade de vida pós-operatória. Conclusões: A lobectomia por RATS e a lobectomia por VATS apresentaram desfechos em 90 dias semelhantes. No entanto, a lobectomia por RATS foi associada a uma redução significativa na taxa de reinternação hospitalar em 90 dias. Estudos maiores são necessários para confirmar esse achado. (Identificador ClinicalTrials.gov: NCT02292914 [http://www.clinicaltrials.gov/])
ABSTRACT Objective: To compare 90-day morbidity in patients undergoing lung lobectomy performed by either robotic-assisted thoracic surgery (RATS) or video-assisted thoracic surgery (VATS). Intraoperative complications, drainage time, length of hospital stay, postoperative pain, postoperative quality of life, and readmissions within 90 days were also compared. Methods: This was a two-arm randomized clinical trial including patients with lung lesions (primary lung cancer or lung metastasis) who were candidates for lung lobectomy. Patients with comorbidities that precluded surgical treatment were excluded. All patients followed the same postoperative protocol. Results: The overall sample comprised 76 patients (39 in the VATS group and 37 in the RATS group). The two groups were similar regarding gender, age, BMI, FEV1 in % of predicted, and comorbidities. Postoperative complications within 90 days tended to be more common in the VATS group than in the RATS group, but the difference was not significant (p = 0.12). However, when only major complications were analyzed, this tendency disappeared (p = 0.58). Regarding postoperative outcomes, the VATS group had a significantly higher number of readmissions within 90 days than did the RATS group (p = 0.029). No significant differences were found regarding intraoperative complications, drainage time, length of hospital stay, postoperative pain, and postoperative quality of life. Conclusions: RATS and VATS lobectomy had similar 90-day outcomes. However, RATS lobectomy was associated with a significant reduction in the 90-day hospital readmission rate. Larger studies are necessary to confirm such a finding. (ClinicalTrials.gov identifier: NCT02292914 [http://www.clinicaltrials.gov/])

Abstract Objective: Empyema is a complication of talc-pleurodesis that may lead to further surgical intervention and death. Therefore, the present study’s objective was to identify the risk factors for the development of post-pleurodesis empyema after talc slurry pleurodesis in order to better select patients for this procedure and minimize its morbidity. Methods: Patients with malignant pleural effusion who underwent talc slurry pleurodesis at the present institution from January 2018 to January 2020 were retrospectively analyzed. Post-pleurodesis empyema was defined as pleural infection up to 30 days after pleurodesis. Using Cox regression analysis, significant prognostic factors for the development of empyema were examined. Results: Of the 86 patients identified for inclusion in the study, 62 were women (72%). Their mean age was 56.3±12.6 years. The median pleural drainage time was 9 days, and 20 patients (23.3%) developed empyema. In the univariate analysis, both drainage time (p = 0.038) and the use of antibiotics prior to pleurodesis (p < 0.001) were risk factors for pleural empyema. Multivariate analysis also identified the use of antibiotics as an independent risk factor (Odds Ratio [OR] 9.81; 95% Confidence Interval [95% CI] 2.87–33.54). Although the pulmonary expansion was not associated with empyema in the multivariate analysis, patients with less than 50% pulmonary expansion had a 4.5-times increased risk of empyema (95% CI 0.90-22.86; p = 0.067), and patients with 50–70% pulmonary expansion had a 3.8-times increased risk of empyema (95% CI 0.98–15; p = 0.053) after pleurodesis. Conclusion: The study suggests that antibiotic therapy prior to talc slurry pleurodesis may increase the risk of developing empyema. Furthermore, pleurodesis should be considered with caution in patients with long-duration chest tube placement and incomplete lung expansion.

BACKGROUND This work describes a chemical study of the essential oil from leaves of Xylopia ochrantha, an endemic Annonaceae species from Brazil, and its activity against Biomphalaria species. Considering its poor solubility in aqueous medium, the essential oil was nanoemulsified to evaluate its action on controlling some mollusc species of genus Biomphalaria, snail hosts of Schistosoma mansoni that causes schistosomiasis, which mainly affects tropical and subtropical countries. OBJECTIVES The main aims of this work were to analyse the chemical composition of essential oil from X. ochrantha, and to evaluate the effect of its nanoemulsion on molluscs of genus Biomphalaria and their oviposition. METHODS Chemical analysis was performed by gas chromatography coupled to mass spectrometry. Nanoemulsions were prepared by a low energy method and characterised by particle size and polydispersity index. Biological assays evaluating the mortality of adult species of B. glabrata, B. straminea and B. tenagophila and their ovipositions upon contact with the most stable nanoemulsion during 24 and 48 h were performed. FINDINGS Chemical analysis by mass spectrometry revealed the majority presence of bicyclogermacrene and germacrene D in the essential oil. The formulation with a hydrophilic-lipophilic balance (HLB) of 9.26 was the most suitable for the oil delivery system. This nanoemulsion caused the mortality in B. tenagophila, B. straminea and B. glabarata of different sizes at levels ranging from 50 to 100% in 48 h. Additionally, the formulation could inhibit the development of deposited eggs. CONCLUSION Thus, these results suggest the use of nanoemulsified essential oil from X. ochrantha as a possible alternative in controlling some Biomphalaria species involved in the schistosomiasis cycle.

ABSTRACT PURPOSE: To assess the effect of aqueous extract of Peumus Boldus (AEPB) on the liver proliferative response after parcial hepatectomy of 70% (PH) in rodents. METHODS: Twenty Wistar rats were divided in two groups: AEPB100 (whose rats received 100mg/Kg of AEPB, once a day, orally, in 4 days prior to the first surgical procedure) and Vehicle (whose rats were treated similarly with distilled water). Both groups underwent PH. After 24 hours the remaining livers were removed for studying the proliferation of hepatocytes by Ki-67 and 2mL of blood were collected for serological assessment: cholesterol, glucose, triglycerides, aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, and total, direct and indirect bilirubin. All data were analyzed by Gaussian distribution. Statistically significant differences between mean values were analyzed using T Student's test. Non-Gaussian data were analyzed using Mann-Whitney's test. RESULTS: The liver of all these rats presented positive staining of Ki-67, indicating liver proliferation. Laboratory results showed no significant difference in serum values between the analyzed groups. The analysis of Ki-67 was significantly more positive in AEPB100 group than in Vehicle group. CONCLUSION: Aqueous extract of Peumus Boldus acute administration exerts significant positive effect on liver regeneration after 24h in rats that underwent parcial hepatectomy, while maintaining unchanged hepatic function.

Resumo Um levantamento atualizado das plantas com sementes e análises relevantes acerca desta biodiversidade são apresentados. Este trabalho se iniciou em 2010 com a publicação do Catálogo de Plantas e Fungos e, desde então vem sendo atualizado por mais de 430 especialistas trabalhando online. O Brasil abriga atualmente 32.086 espécies nativas de Angiospermas e 23 espécies nativas de Gimnospermas e estes novos dados mostram um aumento de 3% da riqueza em relação a 2010. A Amazônia é o Domínio Fitogeográfico com o maior número de espécies de Gimnospermas, enquanto que a Floresta Atlântica possui a maior riqueza de Angiospermas. Houve um crescimento considerável no número de espécies e nas taxas de endemismo para a maioria dos Domínios (Caatinga, Cerrado, Floresta Atlântica, Pampa e Pantanal), com exceção da Amazônia que apresentou uma diminuição de 2,5% de endemicidade. Entretanto, a maior parte das plantas com sementes que ocorrem no Brasil (57,4%) é endêmica deste território. A proporção de formas de vida varia de acordo com os diferentes Domínios: árvores são mais expressivas na Amazônia e Floresta Atlântica do que nos outros biomas, ervas são dominantes no Pampa e as lianas apresentam riqueza expressiva na Amazônia, Floresta Atlântica e Pantanal. Este trabalho não só quantifica a biodiversidade brasileira, mas também indica as lacunas de conhecimento e o desafio a ser enfrentado para a conservação desta flora.
Abstract An updated inventory of Brazilian seed plants is presented and offers important insights into the country's biodiversity. This work started in 2010, with the publication of the Plants and Fungi Catalogue, and has been updated since by more than 430 specialists working online. Brazil is home to 32,086 native Angiosperms and 23 native Gymnosperms, showing an increase of 3% in its species richness in relation to 2010. The Amazon Rainforest is the richest Brazilian biome for Gymnosperms, while the Atlantic Rainforest is the richest one for Angiosperms. There was a considerable increment in the number of species and endemism rates for biomes, except for the Amazon that showed a decrease of 2.5% of recorded endemics. However, well over half of Brazillian seed plant species (57.4%) is endemic to this territory. The proportion of life-forms varies among different biomes: trees are more expressive in the Amazon and Atlantic Rainforest biomes while herbs predominate in the Pampa, and lianas are more expressive in the Amazon, Atlantic Rainforest, and Pantanal. This compilation serves not only to quantify Brazilian biodiversity, but also to highlight areas where there information is lacking and to provide a framework for the challenge faced in conserving Brazil's unique and diverse flora.

OBJECTIVES: This paper discusses the influence of a para-areolar incision in the upper outer quadrant of the breast on the location of the sentinel lymph node in a canine model. METHODS: The sentinel lymph node was marked with technetium-99, which was injected into the subareolar skin of the cranial breast. After the marker had migrated to the axilla, an arcuate para-areolar incision was performed 2 cm from the nipple in the upper outer quadrant. Patent blue dye was then injected above the upper border of the incision. At the marked site, an axillary incision was made, and the sentinel lymph node was identified by gamma probe and/or by direct visualization of the dye. The agreement between the two injection sites and the two sentinel lymph node identification methods was determined. Our sample group consisted of 40 cranial breasts of 23 adult females of the species Canis familiaris. The data were analyzed by using the McNemar test and by determining the kappa agreement coefficient. RESULT: Our findings showed that in 95% of the breasts, the sentinel lymph node was identified by the injection of technetium-99 m into the subareolar region, and in 82% of the cases, the sentinel lymph node was identified by the injection of patent blue dye above the upper border of the incision. The methods agreed 82% of the time. CONCLUSIONS: Previous para-areolar incisions in the upper outer quadrant did not interfere significantly with the biopsy when the dye was injected above the upper border of the incision.

Para avaliar a influência da suplementação com selênio e vitamina E sobre o perfil proteico e metabolismo oxidativo de cordeiros infectados experimentalmente pelo Haemonchus contortus, trinta cordeiros fêmeas foram distribuídos em quatro grupos: G1 (n=10): animais infectados; G2 (n=10): infectados e suplementados; G3 (n=5): controle; e G4 (n=5): não infectados e suplementados. Os grupos 1 e 2 receberam 500 larvas de H. contortus (L3), via oral, por um período de 20 dias, com intervalo de dois dias entre as doses. A suplementação nos grupos 2 e 4 foi realizada no dia zero, com 0,1mg kg-1 de Selenito de sódio (1,67%) e com 2.000UI de vitamina E por via intramuscular (IM). Somente a vitamina E foi reaplicada no dia 30. As coletas de sangue para determinação do perfil proteico (proteína total, albumina, alfa, beta e gamaglobulina) e metabolismo oxidativo (espécies reativas ao ácido tiobarbitúrico-TBARS e a enzima glutationa peroxidase (GSPX) foram realizadas nos dias zero, 20, 30, 45, 60 e 80. OPG foi quantificado nos dias 0, 20 ,45 e 80. Em relação aos valores de proteínas totais, albumina, betaglobulina e gamaglobulina, as principais diferenças foram observadas quando os grupos parasitados foram comparados com o grupo somente suplementado; e este manteve valores mais elevados. Conclui-se que não há influência da suplementação com selênio e vitamina E no perfil proteico e metabolismo oxidativo quando os cordeiros se encontram severamente parasitados por H.contortus.
The objective of the present study was to describe the influence of supplementation with selenium and vitamin E on the protein and oxidative profiles of lambs experimentally infected with Haemonchus contortus. Thirty female lambs were divided into four groups as follows: G1 (n=10): infected animals; G2 (n=10): infected and supplemented; G3 (n=5): control; G4 (n=5): non-infected and supplemented. Groups 1 and 2 received 500 H. contortus larvae (L3) orally for a period of 20 days, with 2-day intervals between doses. Supplementation in groups 2 and 4 was performed on day zero by injecting 0.1mg kg-1 of sodium selenite solution (1.67%) and 2,000IU vitamin E through the intramuscular (IM) route. Vitamin E alone was injected once again on day thirty. The blood samples to determine the protein profile (total protein, albumin, alpha, beta and gamma) and oxidative metabolism (species reactive to thiobarbituric acid and glutathione peroxidase (GSPX) were performed on days zero, 20, 30, 45, 60 and 80. The OPG was quantified on days 0, 20, 45 and 80. Regarding the values of total proteins, albumin, beta and gamma globulins, the main differences were observed when the parasitized groups were compared to the supplemented, non-infected group, the latter exhibiting higher values. It is concluded that there is no influence of supplementation with vitamin E and selenium in the protein profile and oxidative metabolism when the lambs are severely parasitized with H. contortus.

A anemia verminótica é a principal causa de perdas na ovinocultura, incluindo diminuição no ganho médio diário, demora no tempo de recuperação pós-tratamento e óbito. O objetivo deste trabalho foi avaliar o status oxidativo e a recuperação do quadro hematológico de cordeiros com anemia induzida por flebotomia e suplementados ou não com ferro dextrano. Foram utilizados dez cordeiros machos entre cinco e sete meses de idade. O dia zero do experimento foi considerado quando cada animal atingiu o hematócrito 15% após a indução da anemia, sendo alocado em um dos grupos experimentais. O grupo tratado recebeu uma dose única de 25mg-1 kg-1 de peso vivo de uma formulação comercial de ferro dextrano intramuscular e o grupo controle não foi tratado. As coletas de sangue foram feitas nos dias zero, 7, 14 e 21 pós-tratamento. Nos dias sete e 21, os animais do grupo tratado tiveram aumento nos valores de espécies reativas ao ácido tiobarbitúrico (TBARS) e diminuição nos valores dos grupamentos tióis não-protéicos (NPTH) nos dias 7, 14 e 21. No dia sete, o teste de fragilidade osmótica eritrocitária indicou um aumento na resistência da membrana dos eritrócitos dos animais do grupo tratado quando comparado aos animais do grupo controle. A recuperação da série vermelha do sangue (número de eritrócitos, hematócrito e hemoglobina) foi mais rápida no grupo tratado. A suplementação de ferro, apesar de aumentar o estresse oxidativo, acelerou a recuperação do quadro hemático, não aumentando a porcentagem de hemólise pela ação das espécies reativas de oxigênio sobre a membrana eritrocitária.
Anemia due to worm infection is a major cause of loss in the sheep industry, due to deaths, drop in average daily gains and long recovery time following treatment. The present experiment was aimed at evaluating the oxidative status and the recovery of red blood cell (RBC) profile in lambs with induced anemia by bleeding, treated or not with dextran iron. Ten ram lambs 5 to 7 months old were used. Blood samples were drawn every other day and when reached packed cell volume (PCV) of 15% were randomly allocated (day zero) to one of the experimental groups. Treated group received a single dose of 25mg per kg body weight of a commercial formulation of dextran iron, the control group received no treatment. Blood samples were taken on days 0, 7, 14, and 21 after treatment. On days 7 an 21 treated animals presented higher thyobarbituric acid reactive species (TBARS) values, reduced non-protein thiol groups (NPTH) levels were found in the treated group on days 7, 14 and 21. Erythrocyte membrane resistance to osmotic challenge was improved on day 7 in treated animals. Recovery to normal values for the RBC profile was faster in the treated group with significant differences starting on day 7. It was conclude that althouth the iron treatment increased the oxidative stress, it also accelerated recovery of the hematological profile. Moreover, it did not increase hemolysis in anemic blood by the action of oxygen reactive species upon biological membranes.
