ABSTRACT Zinnia sp. and hairy beggartick (Bidens pilosa) plants exhibiting symptoms of possible virus infection were found in the municipality of Santa Bárbara d’Oeste, São Paulo State, Brazil. Flexuous filamentous particles and cytoplasmatic inclusions typical of potyvirus infection were observed by transmission electron microscopy, respectively, in leaf extracts and cells of symptomatic leaves. Infection of both plants with bidens mottle virus (BiMoV) was confirmed by RT-PCR using potyvirus universal primers, followed by nucleotide sequencing of the amplicons. The nearly complete genome sequence of the Brazilian isolate, named BiMoV-BR, is 9700 nucleotides long and shares 95.6 % identity with the corresponding nucleotide sequence of a BiMoV isolate from the United States. BiMoV-BR was mechanically transmitted and caused systemic infection on plants of Zinnia sp., hairy beggarstick, sunflower (Helianthus annuus), and lettuce (Lactuca sativa). Myzus persicae transmitted the virus to Zinnia sp. plants with efficacy of 8 % and 42 %, using one and ten aphids per plant, respectively. This is the first detection of BiMoV in Brazil. Further studies are necessary to evaluate the distribution of this potyvirus in the country.

ABSTRACT Background: The rate of tuberculosis (TB) infection among the prison population (PP) in Brazil is 28 times higher than that in the general population, and prison environment favors the spread of TB. Objective: To describe TB transmission dynamics and drug resistance profiles in PP using whole-genome sequencing (WGS). Methods: This was a retrospective study of Mycobacterium tuberculosis cultivated from people incarcerated in 55 prisons between 2016 and 2019; only one isolate per prisoner was included. Information about movement from one prison to another was tracked. Clinical information was collected, and WGS was performed on isolates obtained at the time of TB diagnosis. Results: Among 134 prisoners included in the study, we detected 16 clusters with a total of 58 (43%) cases of M. tuberculosis. Clusters ranged from two to seven isolates with five or fewer single nucleotide polymorphism (SNP) differences, suggesting a recent transmission. Six (4.4%) isolates were resistant to at least one anti-TB drug. Two of these clustered together and showed resistance to rifampicin, isoniazid, and fluoroquinolones, with 100% concordance between WGS and phenotypic drug-susceptibility testing. Prisoners with clustered isolates had a high amount of movement between prisons (two to eight moves) during the study period. Conclusions: WGS demonstrated the recent transmission of TB within prisons in Brazil. The high movement among prisoners seems to be related to the transmission of the same M. tuberculosis strain within the prison system. Screening for TB before and after the movement of prisoners using rapid molecular tests could play a role in reducing transmission.

Abstract Background The aim of this study was to evaluate disease activity among patients with axial spondyloarthritis (AS) treated with tumor necrosis factor inhibitors (TNFi) and/or nonsteroidal anti-inflammatory drugs (NSAIDs) for at least 12 weeks in private outpatient settings in Brazil. Methods This was a cross-sectional, real-world study conducted in 17 Brazilian private health care institutes. Patients were selected if diagnosed with AS or axial radiographic spondyloarthritis (AxSpA) and treated with NSAIDs or TNFi for at least 12 weeks within the last 26 weeks prior to enrollment. The data were collected from interviewed-based and self-administered questionnaires from patients and physicians. Disease activity was defined as active (≥ 4), low /suboptimal (≥ 2 and < 4) and inactive (< 4) by Bath AS Disease Activity Index (BASDAI) and/or very high (≥ 3.5), high (≥ 2.1 to < 3.5), low (≥ 1.3 to < 2.1), and inactive (< 1.3) by AS Disease Activity Score (ASDAS-CRP). Both patients and physicians’ perceptions of disease control were assessed using a numeric rating scale (NRS; 0—inactive to 10—very active disease). Results The cohort included 378 patients with a mean age of 46 years, and the median time since diagnosis until enrollment was 5.4 years (interquartile range 2.7–10.5). Most patients were treated with TNFi alone (74%), followed by TNFi in combination with NSAID (15%), and NSAID alone (11%). About half AS patients showed active disease and 24% of patients showed low activity/suboptimal disease control despite having been treated for at least 12 weeks. Although TNFi showed better disease control than NSAID, inactive disease was experienced by few patients. The NRS (mean [standard deviation]) score for disease perception was 4.24 (3.3) and 2.85 (2.6) for patients and physicians, respectively. Conclusion This real-world study showed that most AS patients on TNFi and/or NSAID had not achieved an adequate disease control, as almost 75% of them exhibited active disease or low activity/suboptimal disease control. There remains a need for improved disease management among patients with AS.

ABSTRACT Purpose: To describe our experience in the management of retained encrusted ureteral stents using a single session combined endourological approach. Materials and Methods: Patients with retained encrusted ureteral stents who had been submitted to a single session combined endourological approach from June 2010 to June 2018 were prospectively evaluated. Patients were divided according to the Forgotten-Encrusted-Calcified (FECal) classification. The stone burden, surgical intervention, number of interventions until stone free status, operation time, hospital stay, complications, stone analysis, and stone-free rate were compared between groups. ANOVA was used to compare numerical variables, and the Mann-Whitney or Chi-square test to compare categorical variables between groups. Results: We evaluated 50 patients with a mean follow-up of 2.9±1.4 years (mean±SD). The groups were comparable in terms of age, sex, laterality, BMI, comorbidities, ASA, reason for stent passage, and indwelling time. The stone burden was higher for grades IV and V (p=0.027). Percutaneous nephrolithotomy was the most common procedure (p=0.004) for grades IV and V. The number of procedures until the patients were stone-free was 1.92±1.40, and the hospital stay (4.2±2.5 days), complications (22%), and stone analysis (66% calcium oxalate) were similar between groups. The stone-free rate was lower in grades III to V (60%, 54.5%, and 50%). Conclusions: The endoscopic combined approach in the supine position is a safe and feasible technique that allows removal of retained and encrusted stents in a single procedure. The FECal classification seems to be useful for surgical planning.

OBJECTIVES: To compare demographic/clinical/laboratory/treatments and outcomes among children and adolescents with laboratory-confirmed coronavirus disease 2019 (COVID-19). METHODS: This was a cross-sectional study that included patients diagnosed with pediatric COVID-19 (aged <18 years) between April 11, 2020 and April 22, 2021. During this period, 102/5,951 (1.7%) of all admissions occurred in neonates, children, and adolescents. Furthermore, 3,962 severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) detection samples were processed in patients aged <18 years, and laboratory-confirmed COVID-19 occurred in 155 (4%) inpatients and outpatients. Six/155 pediatric patients were excluded from the study. Therefore, the final group included 149 children and adolescents (n=97 inpatients and 52 outpatients) with positive SARS-CoV-2 results. RESULTS: The frequencies of sore throat, anosmia, dysgeusia, headache, myalgia, nausea, lymphopenia, pre-existing chronic conditions, immunosuppressive conditions, and autoimmune diseases were significantly reduced in children and adolescents (p<0.05). Likewise, the frequencies of enoxaparin use (p=0.037), current immunosuppressant use (p=0.008), vasoactive agents (p=0.045), arterial hypotension (p<0.001), and shock (p=0.024) were significantly lower in children than in adolescents. Logistic regression analysis showed that adolescents with laboratory-confirmed COVID-19 had increased odds ratios (ORs) for sore throat (OR 13.054; 95% confidence interval [CI] 2.750-61.977; p=0.001), nausea (OR 8.875; 95% CI 1.660-47.446; p=0.011), and lymphopenia (OR 3.575; 95% CI 1.355-9.430; p=0.010), but also had less hospitalizations (OR 0.355; 95% CI 0.138-0.916; p=0.032). The additional logistic regression analysis on patients with preexisting chronic conditions (n=108) showed that death as an outcome was significantly associated with pediatric severe acute respiratory syndrome (SARS) (OR 22.300; 95% CI 2.341-212.421; p=0.007) and multisystem inflammatory syndrome in children (MIS-C) (OR 11.261; 95% CI 1.189-106. 581; p=0.035). CONCLUSIONS: Half of the laboratory-confirmed COVID-19 cases occurred in adolescents. Individuals belonging to this age group had an acute systemic involvement of SARS-CoV-2 infection. Pediatric SARS and MIS-C were the most important factors associated with the mortality rate in pediatric chronic conditions with COVID-19.

Abstract Coronavirus disease 2019 (COVID-19), caused by the Severe Acute Respiratory Syndrome Coronavirus type 2 (SARS-CoV-2), is the largest pandemic in modern history with very high infection rates and considerable mortality. The disease, which emerged in China’s Wuhan province, had its first reported case on December 29, 2019, and spread rapidly worldwide. On March 11, 2020, the World Health Organization (WHO) declared the COVID-19 outbreak a pandemic and global health emergency. Since the outbreak, efforts to develop COVID-19 vaccines, engineer new drugs, and evaluate existing ones for drug repurposing have been intensively undertaken to find ways to control this pandemic. COVID-19 therapeutic strategies aim to impair molecular pathways involved in the virus entrance and replication or interfere in the patients’ overreaction and immunopathology. Moreover, nanotechnology could be an approach to boost the activity of new drugs. Several COVID-19 vaccine candidates have received emergency-use or full authorization in one or more countries, and others are being developed and tested. This review assesses the different strategies currently proposed to control COVID-19 and the issues or limitations imposed on some approaches by the human and viral genetic variability.

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.

RESUMO A utilização de recursos derivados da própria propriedade agrícola para suprir necessidades dos produtores proporciona a redução de custos com insumos comerciais e a reciclagem de subprodutos, dentre eles, o resíduo líquido da produção de farinha de mandioca, denominado manipueira, que pode configurar-se como importante fonte de adubação. Objetivou-se avaliar o crescimento e a produção de Capsicum chinense Jacq., em função de doses de manipueira associada a proporções de adubo mineral. O estudo foi conduzido em casa-de-vegetação, em delineamento inteiramente casualizado, com os tratamentos distribuídos em esquema fatorial 3 x 5, sendo 3 doses (0, 50 e 100 %) da adubação mineral recomendada para a cultura e 5 doses (0, 25, 50, 100 e 150 m³ ha-1) de manipueira, com 4 repetições. As doses de manipueira influenciaram na produtividade da cultura, apresentando tendência linear. A dose de 150 m3 ha-1 proporcionou produtividade equivalente à obtida com a aplicação de 100 % da adubação mineral recomendada para essa cultura, permitindo, assim, a substituição parcial ou total dessa adubação pela manipueira.
ABSTRACT The use of resources derived from the agricultural property itself to meet the needs of producers promotes the reduction of costs with commercial inputs and recycling of by-products, among them the liquid waste from the cassava flour production, called cassava wastewater, which can be an important fertilization source. This study aimed to evaluate the growth and production of Capsicum chinense Jacq., as a function of cassava wastewater doses associated with mineral fertilizer proportions. The experiment was conducted in a greenhouse, in a completely randomized design, with treatments distributed in a 3 x 5 factorial scheme, corresponding to 3 doses (0, 50 and 100 %) of the mineral fertilization recommended for the crop and 5 doses (0, 25, 50, 100 and 150 m³ ha-1) of cassava wastewater, with 4 replicates. The cassava wastewater doses influenced the crop yield, showing a linear trend. The dose of 150 m3 ha-1 promoted a yield equivalent to that obtained with the application of 100 % of the mineral fertilization recommended for this crop, thus enabling the partial or total replacement of this fertilization by cassava wastewater.

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.

The southern South Atlantic is crucial in the distribution of deep water masses towards other ocean basins. Given the role of the thermohaline circulation in the climatic system, insights into its variations during glacial/interglacial cycles is of great interest. Benthic foraminifera are used in paleoceanographic reconstructions, tracking changes in deep oceanic circulation by means of the distribution of indicator species associated with certain water masses. However, the relationship between benthic foraminifera and water masses is controversial. A sediment core drilled at the North Atlantic Deep Water-Circumpolar Deep Water limit was surveyed for benthic foraminifera in order to determine whether assemblages reflect patterns of deep watermasses distribution during a Middle Pleistocene glaciation event. The assemblages recovered comprised species indicative of both water types, with Circumpolar Deep Water-indicator species being slightly more abundant due to Uvigerina peregrina dominance. In spite of this, the low abundance of other Circumpolar Deep Water-indicator species such as Globocassidulina subglobosa coupled with the evenness in the relative abundance of North Atlantic Deep Water indicator-species preclude the interpretation of Uvigerina peregrina’s dominance in terms of a greater influence of Circumpolar Deep Water at the expense of North Atlantic Deep Water. The latter species, also an indicator of high organic matter fluxes, increases its relative abundance jointly with those of Globigerina bulloides, which suggests that surface productivity influenced deep benthic foraminifera assemblages in the Buenos Aires talus during Middle Pleistocene glaciations.
El océano Atlántico Sur es clave en la distribución de masas de agua profunda hacia otros océanos. Dado el papel que juega la circulación termohalina en el clima, el reconocimiento de variaciones en su distribución durante los ciclos glaciales/interglaciales reviste gran interés. Los foraminíferos bentónicos son utilizados como herramientas de reconstrucción paleoceanográfica, y la existencia de especies asociadas a masas de agua fue utilizada para definir cambios en la circulación oceánica profunda. Sin embargo, la relación entre foraminíferos bentónicos y masas de agua es controversial. Con el objetivo de determinar si las asociaciones de foraminíferos bentónicos reflejan la distribución de las masas de agua profunda durante un evento glacial del Pleistoceno Medio, se analizó un testigo ubicado en el límite entre dos masas de agua profunda: la North Atlantic Deep Water y la Circumpolar Deep Water. En las asociaciones se hallaron especies consideradas indicadoras de ambas masas de agua, aunque algunas especies asociadas a la Circumpolar Deep Water presentan abundancias relativas mayores, siendo Uvigerina peregrina dominante en ciertos niveles. Sin embargo, la escasa abundancia de Globocassidulina subglobosa, asociada a la Circumpolar Deep Water, y la constancia en el porcentaje de especies consideradas indicadoras de la North Atlantic Deep Water impiden atribuir la dominancia de Uvigerina peregrina a una mayor influencia de la Circumpolar Deep Water. El hecho de que esta especie está asociada a flujos elevados de materia orgánica y que su mayor dominancia coincida con aumentos en la abundancia de Globigerina bulloides indica que la productividad superficial fue el factor determinante en la estructuración de las asociaciones de foraminíferos bentónicos en el talud norbonaerense durante el Pleistoceno Medio.

The objective of this ecological and transversal study was to learn about the prevalence of precancerous and cancerous lesions of the cervix and the coverage of screening with the cervical smear test among women in the villages of Jaguapirú and Bororó in the Indian Reserve of Dourados. Data was collected from the Indigenous Health Information Service and the Polo-Base de Dourados/FUNASA Program for the Control of Cervical Cancer, referent to the period 2004-2006. The results showed that the test had mostly taken place among women between 15 and 34 years of age. Screening coverage increased in Jaguapirú and decreased in Bororó. As for cytopathological changes, 5.7% of tests in Jaguapirú indicated premalignant lesions; in the village of Bororó the result was 2.9%. There was evidence of a reduction in the gravity of cervical lesions as the screening program went on. These findings show the importance of control programs for the population under study.

Nitric oxide (NO) is a free radical synthesized from L-arginine by different isoforms NO-synthases. NO possesses multiple and complex biological functions. NO is an important mediator of homeostasis, and changes in its generation or actions can contribute or not to pathological states. The knowledge of effects of NO has been not only important to our understanding of immune response, but also to new tools for research and treatment of various diseases. Knowing the importance of NO as inflammatory mediator in diverse infectious diseases, we decided to develop a revision that shows the participation/effect of this mediator in immune response induced against Giardia spp. Several studies already demonstrated the participation of NO with microbicidal and microbiostatic activity in giardiasis. On the other hand, some works report that Giardia spp. inhibit NO production by consuming the intermediate metabolite arginine. In fact, studies in vitro showed that G. lamblia infection of human intestinal epithelial cells had reduced NO production. This occurs due to limited offer of the crucial substrate arginine (essential aminoacid for NO production), consequently reducing NO production. Therefore, the balance between giardial arginine consumption and epithelial NO production could contribute to the variability of the duration and severity of infections by this ubiquitous parasite.

Cadmium (Cd) in air, drinking water and food has the potential to affect the health of people, mainly those who live in highly industrialized regions. Cd affects placental function, can cross the placental barrier and directly modify fetal development. Once the organism is particularly susceptible to the exposition to the Cd during the perinatal period, and that this metal can be excreted in the milk, the aim of the present work was to study the effects of the constant exposition to drinkable water containing low levels of Cd during the lactation, on the salivary glands of the rat. Female rats received ad libitum drinking water containing 300mg/l of CdCl2 throughout the whole lactation. Control animals received a similar volume of water without Cd. Lactant rats (21 day old) were killed by lethal dose of anesthetic. The salivary glands were separated, fixed in "alfac" solution for 24 h, and serially sectioned. The 6µm thick sections were stained with hematoxylin and eosin. Nuclear glandular parameters were estimated, as well as cytoplasm and cell volume, nucleus/cytoplasm ratio, number and surface density, diameters and cell thickness. Mean body weight was 34.86 g for the control group and 18.56 g for the Cd-treated group. Histologically, the glandular acini were significantly smaller, the gland ducts were similar in both groups studied. The connective tissue was more abundant. In conclusion, the salivary glands (submandibular, parotid and sublingual) showed retarded growth after Cd intoxication.
El cadmio (Cd), presente en el aire, agua potable y alimentos, tiene potencial para afectar la salud humana, principalmente en las regiones altamente industrializadas. El Cd además de afectar la función placentaria, puede atravesar la barrera placentaria y perjudicar directamente el desarrollo fetal. En virtud de que el organismo es particularmente susceptible a la exposición al Cd durante el período perinatal, y que ese metal puede ser excretado en la leche, el objetivo del presente trabajo fue estudiar los efectos de la exposición continua a agua potable conteniendo bajos niveles de Cd durante la lactancia sobre las glándulas salivales de la rata. Ratas hembra recibieron agua potable conteniendo 300mg/l de CdCl2 ad libitum durante toda la lactancia. Animales control recibieron un volumen similar de agua potable sin Cd. Las ratas lactantes (21 días de edad) fueron sacrificadas con una dosis letal de anestésico. Las glándulas salivales fueron separadas, fijadas en "alfac" por 24 h, y cortadas seriadamente. Cortes de 6 µm de espesor fueron teñidos con hematoxilina y eosina. Fueron estimados los parámetros nucleares, los volúmenes citoplasmático y celular, la relación núcleo/citoplasma, densidad numérica, densidad superficial, diámetros y espesor de las paredes de las estructuras glandulares. El peso medio corporal fue 34,86 g para la rata control y 18,56 g para la tratada. Histológicamente, los adenómeros glandulares fueron significativamente menores y los conductos glandulares fueron similares en ambos grupos. La estroma fue más abundante en los animales tratados. En conclusión, las glándulas salivales (submandibular, parótida y sublingual) mostraron retardo del crecimiento en los animales intoxicados por Cd.
