Reuse made by the separation of whey can reduce the waste of human milk. However, the authors are not aware of the literature on treatments in human whey, made available by pasteurization holder, freeze-drying, spray drying, and high hydrostatic pressure. In this context, the present study applied treatments to human whey and evaluated their lipid and immunological quality. Among the results, a different formation in the triacylglycerol profile was evidenced after the application of spray drying and high hydrostatic pressure, while pasteurization and freeze-drying presented ion intensity close to the control human whey. In addition, pasteurization proved to be adequate for lipid nutritional quality and transformation factor-β1 (TGF-β1) concentration, while an increase in interleukin-10 (IL-10) levels was promoted, between 73 and 80%, after freeze-drying, spray drying, and high hydrostatic pressure. Through the principal component analysis, it is noteworthy that the processes presented divergences in terms of the effects caused, with similarity only between pasteurization and freeze-drying in the composition of fatty acids. However, it was observed that all processes were able to maintain the nutrients. Nevertheless, it is relevant to consider individual characteristics presented and the interest in the desired quality, which can be promising as a complementary product to infant feeding.

ABSTRACT As transcatheter aortic valve implantation (TAVI) for aortic stenosis (AS) became widespread, the need for a Heart Team (HT) arose to choose the best treatment. There are few reports regarding its usefulness. Objectives: To analyze treatment outcomes in patients with AS evaluated by a HT for 10 years. Methods: Consecutive enrollment of all patients with AS who were candidates for TAVI between January 2012 and July 2021 to choose the best treatment, including surgical aortic valve replacement (SAVR) and conservative medical management (CMM). Results: Out of 841 patients, 455 were assigned to TAVI (53%), 213 to SAVR (24%), and 183 to CMM (23%). The percentage assigned to TAVI has increased from 48% to 62% over time (p <0.05). Patients who underwent TAVI versus those who underwent SAVR were older (86 ± 7 vs. 83 ± 7 years), had a higher EUROSCORE II (6.2, 95% CI 5.7-6.6 vs. 5.6; 95% CI 4.4-6.5) and were frailer (1.62 ± 1 vs. 0.91 ± 1), in all cases p <0.01. Actuarial survival (95% CI) at 1 and 2 years was 88% (84-91%) and 82% (77-86%) for TAVI, 83% (76-88%) and 78% (70-84%) for SAVR, and 70% (60-87%) and 59% (48-68%) for CMM, respectively (p <0.001). Conclusions: For the first 10 years after a Heart Team was established for AS decision-making, approximately half of the patients were assigned to TAVI, and the rest were equally assigned in halves to either surgery or observation. Survival for patients who received interventions was similar at 2 years and higher than in those who did not.

RESUMEN La difusión del reemplazo valvular aórtico percutáneo (TAVI) en la estenosis aórtica (EAo) generó la creación de un Heart Team (HT), para elegir el mejor tratamiento. Existen pocos reportes sobre su utilidad. Objetivos: analizar los resultados del tratamiento de los pacientes con EAo evaluados por un HT durante 10 años Material y métodos: Inclusión consecutiva de todos los pacientes con EAo candidatos a TAVI entre enero del 2012 y julio del 2021 para seleccionar el mejor tratamiento, incluyendo además Cirugía de reemplazo valvular aórtico (CRVA) y Tratamiento médico conservador (TMC). Resultados: De 841 pacientes, se asignaron a TAVI 455 (53%), CRVA 213 (24%) y TMC 183 (23%). El porcentaje asignado a TAVI aumentó con el tiempo de 48 a 62% (p < 0,05). Los pacientes que fueron a TAVI, con respecto a los enviados a CRVA, eran mayores (86 ± 7 vs 83 ± 7 años), con mayor EUROSCORE II (6,2, IC95% 5,7-6,6 vs 5,6, IC95% 4,4-6,5) y más frágiles (1,62 ± 1 vs 0,91 ± 1), en todos los casos p <0,01. La sobrevida actuarial (IC 95%) a 1 y a 2 años fue, para TAVI 88% (84-91%) y 82% (77-86%), para CRVA 83% (76-88%) y 78% (70-84%) y para TMC 70% (60-87%) y 59% (48-68%) respectivamente (p <0,001). Conclusiones: Durante los primeros 10 años de establecido un Heart Team para la toma de decisiones en EAo, se asignaron a TAVI aproximadamente la mitad y el resto se asignó por mitades a cirugía u observación. La sobrevida de los pacientes intervenidos fue similar a 2 años y mayor que la de los no intervenidos.

Abstract Background Cardiovascular diseases (CVDs) are the main cause of morbidity and mortality in Brazil. Objective To provide population-based data on prevalence and factors associated with CVD risk factors. Methods Individuals aged ≥20 years from two editions of the cross-sectional Health Survey of São Paulo focusing on Nutrition (ISA-Nutrition), performed in Sao Paulo city in 2008 (n=590) and 2015 (n=610), were evaluated for: obesity, central obesity, waist/height ratio, high blood pressure (HBP), dyslipidemia, diabetes, and number of CVD risk factors ≥3. Prevalence was estimated according to complex survey procedures. Factors associated with cardiovascular risk factors were assessed using logistic regression, with statistical significance of p<0.05. Results Obesity and older age were associated with higher odds of all cardiovascular risk factors investigated, except for dyslipidemia. HBP was positively associated with being Black/Brown and negatively associated with being physicaly active in leisure time. Women were more likely to have increased adiposity indicators and three or more cardiovascular risk factors than men. Those with higher education had lower chances of having diabetes, HBP and dyslipidemia, and those with higher income had higher chances of having three or more risk factors. Former smokers had higher odds of diabetes, obesity, and high waist/height ratio, and smokers had higher odds of high non-HDL cholesterol levels. From 2008 to 2015, there was an increase (p<0.001) in the prevalence of diabetes (6.9% to 17.3%), HBP (31.9% to 41.8%), dyslipidemia (51.3% to 67.6%), and number of CVD risk factors ≥3 (18.9% to 34.1%). Conclusion This study shows increasing prevalence of CVD risk factors in adult population in Sao Paulo and may support the definition of target groups and priority actions on CVD prevention and treatment.

Abstract Recent years have seen a significant increase in the number of patents related to products and/or processes from aquatic organisms. Therefore, this paper aims to identify patent documents related to fishery resources available in the Brazilian patent system of the National Institute of Industrial Property. The research involved patents deposited/provided between 1999 and 2019, with the search in the system occurring through the descriptors: fish(s), mollusk(s), crustacean(s), and algae(s). A total of 363 records were found, where the group of fish presented the highest representation (40%), followed by algae (35%), crustaceans (14%), and mollusks (10%). The apex of 34 patent applications was found in the year 2011. Moreover, the results showed that the inventions registered are directed mainly to food, drugs, biocides, cosmetics, cultivation, processing and beneficiation, water treatment, patents for sustainable technologies (green patents), and biotechnology. Brazil holds most patent applications, followed by the United States of America (USA), which focuses its patent applications mainly on algae and fish. Considering the Brazilian biodiversity and the country’s technological development in recent years, Brazil needs to expand its technological autonomy and competitive capacity in the aquaculture and fisheries sector, mainly through the strengthening of R&D and innovation activities.

ABSTRACT Visceral leishmaniasis (VL) is mainly caused by Leishmania (Leishmania) donovani and Leishmania (L.) infantum; however, other Leishmania species have been associated with VL. We report a case of a patient simultaneously diagnosed with VL caused by Leishmania (L.) amazonensis and Hodgkin’s lymphoma. After treatment with liposomal amphotericin B and chemotherapy, the patient presented a clinical cure. This case report reinforces the hypothesis that other Leishmania species can cause visceral lesions mainly related to immunosuppression.

ABSTRACT Background: Domestic pigeons carry pathogens in their droppings, posing a potential public health problem. Methods: The phenotypic and genotypic antimicrobial resistances of Staphylococcus aureus and Enterococcus faecium in the feces of urban pigeons near hospitals with intensive care units were measured. Results: Twenty-nine samples showed Enterococcus growth, whereas one was positive for S. aureus. The S. aureus isolate was sensitive to the antibiotics tested via antibiogram, however resistance genes were identified. E. faecium isolates showed phenotypic resistance to gentamicin, erythromycin, and ciprofloxacin. Conclusions: Antimicrobial profiles harmful to health were demonstrated in bacterial pathogens isolated from the external environment of hospitals.

RESUMO Nós relatamos a ocorrência do lagarto Gymnophthalmus underwoodi no município de Belém, estado do Pará, Brasil. Este é o primeiro registro ao sul do Rio Amazonas, provavelmente como resultado de uma introdução acidental por navios que atracam em Belém, o mesmo caminho sugerido para a introdução de outra espécie exótica de lagarto recentemente encontrada na cidade. Nós também determinamos a identidade de alguns espécimes de Gymnophthalmus dos estados do Amapá e Pará, através de dados morfológicos externos e moleculares, confirmando que, até o momento, G. vanzoi é o único Gymnophthalmus ocorrendo nos enclaves de savana desses estados. Por fim, nós fornecemos um novo mapa de distribuição para as espécies de Gymnophthalmus, incluindo o novo registro de ocorrência de G. underwoodi para o estado do Pará, onde ela pode ser considerada como uma espécie invasiva.

ABSTRACT We report the occurrence of the lizard Gymnophthalmus underwoodi in the municipality of Belém, state of Pará, Brazil. This is the first record of that species south of the Amazonas River, probably because of an accidental introduction by ships that dock in Belém, the same pathway suggested for the recent introduction of another species of exotic lizard recently recorded in the city. We also determined the identity of some specimens of Gymnophthalmus from the states of Amapá and Pará through external morphology and molecular data, confirming that, until now, G. vanzoi is the only Gymnophthalmus occurring in the savanna enclaves of those states. Finally, we provide a new distribution map for the species of Gymnophthalmus, including the new occurrence record for G. underwoodi for the state of Pará, where it can be considered as an invasive species.

RESUMO Objetivos: Determinar a associação entre a necessidade de tratamento ortodôntico e o bullying autorrelatado e seu impacto na autoestima dos adolescentes. Métodos: A amostra foi composta por 160 escolares de 11 a 14 anos, matriculados em escolas públicas. A história de bullying foi avaliada por meio do Questionário Crozier; adaptado por Dimmock (1999). A autoestima foi determinada por meio do Global Negative Self-Evaluation Scale (GSE). A necessidade normativa de tratamento ortodôntico foi determinada pelo Componente de Saúde Bucal (DHC) e a necessidade percebida, pelo Componente Estético (AC) do Índice de Necessidade de Tratamento Ortodôntico (IOTN). Foram realizadas análises individuais das associações com a história de bullying (desfecho). Resultados: As variáveis que apresentaram P ? 0.20 nas análises individuais foram testadas em modelo de regressão logística múltipla, permanecendo no modelo as variáveis com P ? 0.05. Foram estimados os odds ratios com os intervalos de confiança. De acordo com os resultados, 72.5% dos escolares relataram história de bullying. Os escolares que apresentaram impacto negativo na qualidade de vida relacionado aos sintomas bucais e autoestima negativa tiveram 4.59 e 5.44 vezes mais chance, respectivamente, de relatarem história de bullying (P < 0.05), e não sofreram influência da necessidade de tratamento ortodôntico normativa e percebida. Conclusão: A história de bullying não foi influenciada pela necessidade de tratamento ortodôntico, mas pela baixa autoestima dos adolescentes.

ABSTRACT Objective: To determine the association between orthodontic treatment need and the self-reported bullying, and its impact on adolescents’ self-esteem. Methods: The sample consisted of 160 schoolchildren from 11 to 14 years of age, enrolled in public schools. The history of bullying was evaluated by means of the Crozier; Dimmock adapted Questionnaire (1999). Self-esteem was determined by means of the Global Negative Self-Evaluation Scale (GSE). The normative orthodontic treatment need was determined by the Dental Health Component (DHC) and perceived need, by Aesthetic Component (AC) of the Index of Orthodontic Treatment Need (IOTN). Individual analyses were made of the associations with the history of bullying (outcome). Results: The variables that presented P ? 0.20 in the individual analyses were tested in a multiple logistic regression model, and variables with P ? 0.05 remained in the model. The odds ratios with the intervals of confidence were estimated. According to the results 72.5% of the schoolchildren reported a history of bullying. The schoolchildren who presented negative impact on the quality of life related to oral symptoms and negative self-esteem were observed to have 4.59 and 5.44 times more chance, respectively to report a history of bullying (P < 0.05), which did not suffer the influence of normative and perceived orthodontic treatment need. Conclusion: The history of bullying was not influenced by orthodontic treatment need, but by the low self-esteem of adolescents.

OBJECTIVES: To prospectively evaluate demographic, anthropometric and health-related quality of life (HRQoL) in pediatric patients with laboratory-confirmed coronavirus disease 2019 (COVID-19) METHODS: This was a longitudinal observational study of surviving pediatric post-COVID-19 patients (n=53) and pediatric subjects without laboratory-confirmed COVID-19 included as controls (n=52) was performed. RESULTS: The median duration between COVID-19 diagnosis (n=53) and follow-up was 4.4 months (0.8-10.7). Twenty-three of 53 (43%) patients reported at least one persistent symptom at the longitudinal follow-up visit and 12/53 (23%) had long COVID-19, with at least one symptom lasting for >12 weeks. The most frequently reported symptoms at the longitudinal follow-up visit were headache (19%), severe recurrent headache (9%), tiredness (9%), dyspnea (8%), and concentration difficulty (4%). At the longitudinal follow-up visit, the frequencies of anemia (11% versus 0%, p=0.030), lymphopenia (42% versus 18%, p=0.020), C-reactive protein level of >30 mg/L (35% versus 0%, p=0.0001), and D-dimer level of >1000 ng/mL (43% versus 6%, p=0.0004) significantly reduced compared with baseline values. Chest X-ray abnormalities (11% versus 2%, p=0.178) and cardiac alterations on echocardiogram (33% versus 22%, p=0.462) were similar at both visits. Comparison of characteristic data between patients with COVID-19 at the longitudinal follow-up visit and controls showed similar age (p=0.962), proportion of male sex (p=0.907), ethnicity (p=0.566), family minimum monthly wage (p=0.664), body mass index (p=0.601), and pediatric pre-existing chronic conditions (p=1.000). The Pediatric Quality of Live Inventory 4.0 scores, median physical score (69 [0-100] versus 81 [34-100], p=0.012), and school score (60 [15-100] versus 70 [15-95], p=0.028) were significantly lower in pediatric patients with COVID-19 at the longitudinal follow-up visit than in controls. CONCLUSIONS: Pediatric patients with COVID-19 showed a longitudinal impact on HRQoL parameters, particularly in physical/school domains, reinforcing the need for a prospective multidisciplinary approach for these patients. These data highlight the importance of closer monitoring of children and adolescents by the clinical team after COVID-19.

Abstract Objective: To analyze the impact of vacuum-assisted venous drainage (VAVD) on arterial pump flow in a simulated pediatric cardiopulmonary bypass circuit utilizing a centrifugal pump (CP) with an external arterial filter. Methods: The simulation circuit consisted of a Quadrox-I Pediatric oxygenator, a Rotaflow CP (Maquet Cardiopulmonary AG, Rastatt, Germany), and a custom pediatric tubing set primed with Lactated Ringer's solution and packed red blood cells. Venous line pressure, reservoir pressure, and arterial flow were measured with VAVD turned off to record baseline values. Four other conditions were tested with progressively higher vacuum pressures (-20, -40, -60, and -80 mmHg) applied to the baseline cardiotomy pressure. An arterial filter was placed into the circuit and arterial flow was measured with the purge line in both open and closed positions. These trials were repeated at set arterial flow rates of 1500, 2000, and 2500 mL/min. Results: The use of progressively higher vacuum caused a reduction in effective arterial flow from 1490±0.00 to 590±0.00, from 2020±0.01 to 1220±0.00, and from 2490±0.0 to 1830±0.01 mL/min. Effective forward flow decreased with increased levels of VAVD. Conclusion: The use of VAVD reduces arterial flow when a CP is used as the main arterial pump. The reduction in the forward arterial flow increases as the vacuum level increases. The loss of forward flow is further reduced when the arterial filter purge line is kept in the recommended open position. An independent flow probe is essential to monitor pump flow during cardiopulmonary bypass.

OBJECTIVES: The aim of this study was to determine whether a restrictive compared to a liberal fluid therapy will increase postoperative acute kidney injury (AKI) in patients with severe preeclampsia. METHODS: A total of 46 patients (mean age, 32 years; standard deviation, 6.8 years) with severe preeclampsia were randomized to liberal (1500 ml of lactated Ringer’s, n=23) or restrictive (250 ml of lactated Ringer’s, n=23) intravenous fluid regimen during cesarean section. The primary outcome was the development of a postoperative renal dysfunction defined by AKI Network stage ≥1. Serum cystatin C and neutrophil gelatinase-associated lipocalin (NGAL) were evaluated at postoperative days 1 and 2. ClinicalTrials.gov: NCT02214186. RESULTS: The rate of postoperative AKI was 43.5% in the liberal fluid group and 43.5% in the restrictive fluid group (p=1.0). Intraoperative urine output was higher in the liberal (116 ml/h, IQR 69-191) than in the restrictive fluid group (80 ml/h, IQR 37-110, p<0.05). In both groups, serum cystatin C did not change from postoperative day 1 compared to the preoperative period and significantly decreased on postoperative day 2 compared to postoperative day 1 (p<0.05). In the restrictive fluid group, NGAL levels increased on postoperative day 1 compared to the preoperative period (p<0.05) and decreased on postoperative day 2 compared to postoperative day 1 (p<0.05). CONCLUSION: Among patients with severe preeclampsia, a restrictive fluid regimen during cesarean section was not associated with increased postoperative AKI.

ABSTRACT In experimental infection with Strongyloides venezuelensis, the acute and recovery phases can be distinguished, unlike human infections caused by Strongyloides stercoralis. The objective of this study was to evaluate the production of anti-Strongyloides IgG antibodies and the recognition of immunogenic protein bands during the acute and the recovery phases in rats experimentally infected with S. venezuelensis. Rats were infected subcutaneously with 400 or 4,000 S. venezuelensis infective larvae. The acute phase was characterized by elimination of a large number of eggs in the faeces on days 6-14 post infection; the recovery phase was characterized by the resolution of the infection between days 30 and 35 post infection. Differences in IgG levels were observed in the acute and the recovery phases. Different antigenic fractions were recognized in both phases of infection. It is concluded that proteins within the 30-40 kDa range are immunoreactive markers for both the acute and the recovery phases in rats experimentally infected with S. venezuelensis, particularly using membrane antigen.

RESUMO: A estrutura da assembleia de peixes em uma área portuária na Baía de São Marcos (Costa Amazônica) foi analisada com base nas distribuições espaciais e temporais para identificar potenciais mudanças na resposta aos aumentos de pressão antrópica associados às atividades industriais e portuárias na região. As amostras foram realizadas entre março de 2011 a novembro de 2015. A composição da ictiofauna foi representada por um total de 56 espécies, distribuídas em 15 ordens e 29 famílias. As capturas foram dominadas por Genyatremus luteus (Bloch, 1790), mas Sciades proops (Valenciennes, 1840) foi o mais representativo em termos de biomassa. A avaliação sazonal da assembleia de peixe não revelou diferença significativa. Entretanto, houve diferença entre os locais de captura onde abundância, biomassa e diversidade de Shannon foram mais relevantes no Ponto 1 e a equitabilidade no Ponto 4. A análise NMDS e o teste ANOSIM entre os meses e entre os locais de amostragem, com base na composição de espécies, revelaram uma diferenciação sazonal associado aos meses chuvosos e de estiagem, bem como uma diferenciação espacial, em função de um gradiente de profundidade e hidrodinâmica, resultante da maior distância das áreas de mangue. A baixa diversidade registrada podem ser reflexos das atividades portuárias que historicamente ocorrem na área investigada. Porém, ainda sim, percebeu-se uma manutenção da diversidade regional, ao longo do período em análise. Assim, as escalas temporais e espaciais tornam-se importantes para detecção e compreensão da biodiversidade de peixes em um estuário amazônico, refletindo, a importância dos manguezais para a manutenção da diversidade ictiofaunística na área. Mediante este contexto, o presente estudo pode subsidiar possíveis projetos de conservação na área, uma vez que informações desta natureza são quase inexistentes para peixes estuarinos da Amazônia maranhense.

ABSTRACT: The fish assemblage structure in a port area in São Marcos Bay (Amazonic coast) was evaluated based on the spatial and temporal distributions to identify potential changes in response to anthropic pressure increases associated with industrial and port activities in region. The samples were taken between March 2011 and November 2015. The ichthyofauna was represented by a total of 56 species, distributed in 15 orders and 29 families. Captures were dominated by Genyatremus luteus (Bloch, 1790), but Sciades proops (Valenciennes, 1840) was the most representative in terms of biomass. Seasonal distributions of fish assemblage did not reveal significant differences. However, there was a difference between catch sites, abundance, biomass and Shannon diversity index was higher in the Site 1 and evenness in Site 4. The analysis NMDS and the test ANOSIM between months and between sampling sites, based on species composition, revealed a seasonal differentiation associated with the rainy and drought months, as well as spatial differentiation, in function of a depth gradient and hydrodynamics, resulting from greater distance from mangrove areas. The low diversity recorded may be a reflection of port activities that historically occur in the area investigated. However, there was still a maintenance of regional diversity throughout the period under analysis. Thus, temporal and spatial scales become important for the detection and understanding of fish biodiversity in an Amazonian estuary, reflecting, the importance of mangroves for the maintenance of the ichthyofaunistic diversity in the area. In this context, the present study may subsidize possible conservation projects in the area since information of this nature is almost non-existent for estuarine fish from the Maranhão Amazon.
