Abstract: Pt Es En

A cardiomiopatia hipertrófica (CMH) é uma forma de doença do músculo cardíaco de causa genética, caracterizada pela hipertrofia das paredes ventriculares. O diagnóstico requer detecção por métodos de imagem (Ecocardiograma ou Ressonância Magnética Cardíaca) de qualquer segmento da parede do ventrículo esquerdo com espessura > 15 mm, sem outra causa provável. A análise genética permite identificar mutações de genes codificantes de diferentes estruturas do sarcômero responsáveis pelo desenvolvimento da CMH em cerca de 60% dos casos, permitindo o rastreio de familiares e aconselhamento genético, como parte importante do manejo dos pacientes e familiares. Vários conceitos sobre a CMH foram recentemente revistos, incluindo sua prevalência de 1 em 250 indivíduos, não sendo, portanto, uma doença rara, mas subdiagnosticada. A vasta maioria dos pacientes é assintomática. Naqueles sintomáticos, a obstrução do trato de saída do ventrículo esquerdo (OTSVE) é o principal distúrbio responsável pelos sintomas, devendo-se investigar a sua presença em todos os casos. Naqueles em que o ecocardiograma em repouso ou com Manobra de Valsalva não detecta gradiente intraventricular significativo (> 30 mmHg), devem ser submetidos à ecocardiografia com esforço físico para detecção da OTSVE.   Pacientes com sintomas limitantes e grave OTSVE, refratários ao uso de betabloqueadores e verapamil, devem receber terapias de redução septal ou uso de novas drogas inibidoras da miosina cardíaca. Por fim, os pacientes adequadamente identificados com risco aumentado de morta súbita podem receber medida profilática com implante de cardiodesfibrilador implantável (CDI).

La miocardiopatía hipertrófica (MCH) es una forma de enfermedad cardíaca de origen genético, caracterizada por el engrosamiento de las paredes ventriculares. El diagnóstico requiere la detección mediante métodos de imagen (Ecocardiograma o Resonancia Magnética Cardíaca) que muestren algún segmento de la pared ventricular izquierda con un grosor > 15 mm, sin otra causa probable. El análisis genético permite identificar mutaciones en genes que codifican diferentes estructuras del sarcómero responsables del desarrollo de la MCH en aproximadamente el 60% de los casos, lo que permite el tamizaje de familiares y el asesoramiento genético, como parte importante del manejo de pacientes y familiares. Varios conceptos sobre la MCH han sido revisados recientemente, incluida su prevalencia de 1 entre 250 individuos, por lo tanto, no es una enfermedad rara, sino subdiagnosticada. La gran mayoría de los pacientes son asintomáticos. En los casos sintomáticos, la obstrucción del tracto de salida ventricular izquierdo (TSVI) es el trastorno principal responsable de los síntomas, y su presencia debe investigarse en todos los casos. En aquellos en los que el ecocardiograma en reposo o la maniobra de Valsalva no detecta un gradiente intraventricular significativo (> 30 mmHg), deben someterse a ecocardiografía de esfuerzo para detectar la obstrucción del TSVI. Los pacientes con síntomas limitantes y obstrucción grave del TSVI, refractarios al uso de betabloqueantes y verapamilo, deben recibir terapias de reducción septal o usar nuevos medicamentos inhibidores de la miosina cardíaca. Finalmente, los pacientes adecuadamente identificados con un riesgo aumentado de muerte súbita pueden recibir medidas profilácticas con el implante de un cardioversor-desfibrilador implantable (CDI).

Hypertrophic cardiomyopathy (HCM) is a form of genetically caused heart muscle disease, characterized by the thickening of the ventricular walls. Diagnosis requires detection through imaging methods (Echocardiogram or Cardiac Magnetic Resonance) showing any segment of the left ventricular wall with a thickness > 15 mm, without any other probable cause. Genetic analysis allows the identification of mutations in genes encoding different structures of the sarcomere responsible for the development of HCM in about 60% of cases, enabling screening of family members and genetic counseling, as an important part of patient and family management. Several concepts about HCM have recently been reviewed, including its prevalence of 1 in 250 individuals, hence not a rare but rather underdiagnosed disease. The vast majority of patients are asymptomatic. In symptomatic cases, obstruction of the left ventricular outflow tract (LVOT) is the primary disorder responsible for symptoms, and its presence should be investigated in all cases. In those where resting echocardiogram or Valsalva maneuver does not detect significant intraventricular gradient (> 30 mmHg), they should undergo stress echocardiography to detect LVOT obstruction. Patients with limiting symptoms and severe LVOT obstruction, refractory to beta-blockers and verapamil, should receive septal reduction therapies or use new drugs inhibiting cardiac myosin. Finally, appropriately identified patients at increased risk of sudden death may receive prophylactic measure with implantable cardioverter-defibrillator (ICD) implantation.

Abstract The present study aimed to investigate the socioeconomic and obstetric characteristics of adolescent mothers and the complications they cause to maternal and neonatal health. This baseline data analysis of the MINA-Brazil birth cohort was conducted in the municipality of Cruzeiro do Sul, state of Acre, Brazil. The chi-square test was used to compare characteristics of adolescent and adult postpartum women, and multiple Poisson regression models with robust variance were used to assess associated factors. Among the postpartum women, 26.2% (95%CI: 24.0-28.4) were adolescents. Factors associated with childbirth in adolescence included: nine years or less of schooling (adjPR:1.36; 95%CI: 1.14-1.61), belongs to the lowest quartiles of the wealth index (1st quartile: adjPR:1.40; 95%CI: 1.08-1.80) (2nd quartile: adjPR:1.37; 95%CI: 1.08-1.74), primigravidae (adjPR:3.69; 95%CI: 2.98-4.57), low pre-pregnancy BMI (adjPR:1.28; CI95%: 1.04-1.57), urinary tract infection during pregnancy (adjPR:1.25; CI95%: 1.07-1.46) and less than six prenatal consultations (adjPR:1.42; 95%CI: 1.21-1.66). Poverty, little schooling, primigravidae, low pre-pregnancy BMI, urinary tract infection during pregnancy and few prenatal consultations were associated with childbirth during adolescence in a municipality in the Northern region of Brazil.

Resumo O objetivo do estudo foi investigar as características socioeconômicas e obstétricas de parturientes adolescentes e suas complicações sobre a saúde materna e neonatal. Trata-se de uma análise de dados da linha de base da coorte de nascimentos MINA-Brasil conduzida no município de Cruzeiro do Sul, estado do Acre. Utilizou-se teste qui-quadrado para comparar características das puérperas adolescentes com as adultas e modelos múltiplos de regressão de Poisson com variância robusta para avaliar fatores associados. Entre as puérperas estudadas, 26,2% (IC95%: 24,0-28,4) eram adolescentes. Os fatores associados ao parto na adolescência foram ter nove anos ou menos de estudo (RPaj:1,36; IC95%: 1,14-1,61), pertencer aos menores quartis do índice de riqueza (1° quartil: RPaj:1,40; IC95%: 1,08-1,80) (2° quartil: RPaj:1,37; IC95%: 1,08-1,74), ser primigesta (RPaj:3,69; IC95%: 2,98-4,57), baixo IMC pré-gestacional (RPaj:1,28; IC95%: 1,04-1,57), infecção urinária na gravidez (RPaj:1,25; IC95%: 1,07-1,46) e menos de seis consultas de pré-natal (RPaj:1,42; IC95%: 1,21-1,66). Pobreza, baixa escolaridade, primigestação, baixo IMC pré-gestacional, infecção urinária na gestação e menor número de consultas de pré-natal foram associados ao parto na adolescência em município da região Norte do Brasil.

Resumo O vólvulo gástrico mesentero-axial é uma entidade rara, caracterizada por rotação anómala do estômago sobre o seu menor eixo com potencial obstrução do outlet gástrico, que, se não for abordada atempadamente, pode associar-se a significativa morbilidade e mortalidade. Descrevemos o caso clínico de uma mulher de 30 anos de idade que se apresentou com quadro sugestivo de obstrução gastrointestinal com um dia de evolução, associado a significativa elevação dos níveis séricos de lactatos. A TC abdominal e pélvica demonstrou significativa distensão e alteração da posição do estômago, com inversão da relação espacial entre a junção esófago-gástrica e o antro/piloro, assim como pneumatose parietal gástrica e aeroportia. Perante estes achados, foi sugerido o diagnóstico de vólvulo gástrico mesentero-axial complicado com isquemia gástrica. Seguiu-se cirurgia exploradora, que confirmou o diagnóstico, tendo sido realizada gastrectomia total.

Abstract Mesenteroaxial gastric volvulus is a rare condition characterized by anomalous rotation of the stomach on its shortest axis potentially resulting in gastric outlet obstruction; if management is delayed, it can result in significant morbidity and mortality. We describe the clinical case of a 30-year-old woman who presented with symptoms/signs suggestive of gastrointestinal obstruction with onset in the previous day, associated with significant elevation of blood lactate levels. Abdominal and pelvic CT revealed significant distension and anomalous position of the stomach with spatial inversion of the positions of the esophagogastric junction and the gastric antrum/ pylorus, as well as gastric pneumatosis and portal venous gas. Considering these findings, a diagnosis of mesenteroaxial gastric volvulus complicated by gastric ischemia was suggested. Exploratory surgery confirmed the diagnosis and the patient underwent total gastrectomy.

ABSTRACT Scorpion envenoming is considered a public health problem in Brazil. A recent study described a variation in the clinical outcome of envenoming by Tityus obscurus in two populations separated by 850 km in the northeastern Amazon region. Our aim was to evaluate whether such clinical and toxinological variations are associated with underlying differences in genetic diversity between these two T. obscurus populations. We obtained DNA from five individuals of each population, in the municipalities of Belém and Santarém, located east and west of the state of Pará, Brazil, respectively. Gene regions encoding mitochondrial DNA (mtDNA) markers cytochrome oxidase subunit I (COI) and ribosomal 16S RNA (16S) were amplified and sequenced. Phylogenetic analyses were performed using maximum likelihood (ML) and Bayesian inferences (BA) for both molecular data (COI and 16S). The sampled T. obscurus populations corresponded to two distinct mtDNA lineages (genetic distance COI K2 P = 0.08 to 0.13; 16S K2 P = 0.10 to 0.11) with no shared mutations between groups and well supported by ML and BA inferences. Based on the divergence values found between eastern and western populations (COI, 0.07 to 0.12; 16S, 0.10), our study confirms the genetic heterogeneity of T. obscurus populations within the state of Pará, which correlates with observed venom and clinical differences, and reinforces the need for mapping the distribution of haplotypes throughout the geographic range of T. obscurus, to aid in future epidemiological, toxinological, and evolutionary studies.

RESUMO O envenenamento por escorpiões é considerado um problema de saúde pública no Brasil. Um estudo recente descreve a variação do quadro clínico de envenenamento por Tityus obscurus em duas populações separadas por uma distância de 850 km no nordeste da Amazônia. O objetivo deste estudo foi avaliar se tais variações clínicas e toxicológicas estão associadas a diferenças subjacentes na diversidade genética entre essas duas populações de T. obscurus. Obtivemos DNA de cinco indivíduos de cada população nos municípios de Belém e Santarém, localizados a leste e oeste do estado do Pará, Brasil, respectivamente. Regiões gênicas que codificam marcadores de DNA mitocondrial (mtDNA) citocromo oxidase subunidade I (COI) e RNA ribossômico 16S (16S) foram amplificadas e sequenciadas. As análises filogenéticas foram realizadas por máxima verossimilhança (ML) e inferência Bayesiana (BA) para ambos os dados moleculares (COI e 16S). As populações de T. obscurus amostradas corresponderam a duas linhagens distintas de mtDNA (distância genética COI K2 P = 0,08 a 0,13; 16S K2 P = 0,10 a 0,11) sem mutações compartilhadas entre os grupos, e bem corroboradas por inferências ML e BA. Com base nos valores de divergência encontrados entre as populações oriental e ocidental (COI, 0,07 a 0,12; 16S, 0,10), nosso estudo confirma a heterogeneidade genética das populações de T. obscurus no estado do Pará. Os resultados são congruentes com as diferenças observadas no quadro clínico dos acidentes e toxicidade do veneno, e reforçam a necessidade de mapear a distribuição de haplótipos em toda a distribuição geográfica de T. obscurus, para auxiliar em futuros estudos epidemiológicos, toxinológicos e evolutivos.

Abstract Objective The study aims to demonstrate an evaluation method to predict the functional success of total wrist arthrodesis (TWA) and assist its indication. Methods A prospective study including ten patients submitted to (TWA) posttraumatic arthritis. Exclusion criteria were patients who lost postoperative follow-up or incomplete information in the medical record. The objective functional assessment (handgrip strength, three-point pinch, lateral pinch and pulp-pulp pinch) and the subjective functional assessment (DASH, PRWE, EVA) were evaluated in 3 different periods: (1) Before surgery without articular anesthesia, (2) Before surgery under articular anesthesia and (3) 12 weeks after the surgical procedure. Results There was an increase in handgrip strength in all three pinches measurements after pain relief, both after joint anesthesia and after the consolidation of the arthrodesis (p < 0.05). In the comparisons between the subjective evaluations (DASH, PRWE and VAS), the patients had better scores in the postoperative evaluation after 12 weeks (p < 0.05). There was no statistical difference when comparing the mean strength values found after anesthesia and after 12 weeks of TWA. Conclusion the outcomes could propose an assessment protocol for patients with indication for TWA, in which patients with good response to intra-articular anesthetic infiltration would benefit from the effects of the surgical procedure.

Resumo Objetivo O estudo tem como objetivo demonstrar um método de avaliação para predizer o sucesso funcional da artrodese total do punho (ATP) e auxiliar na sua indicação. Métodos Um estudo prospectivo incluindo dez pacientes submetidos a ATP por artrite pós-traumática. Os critérios de exclusão foram pacientes que perderam o acompanhamento pós-operatório ou informações incompletas no prontuário. A avaliação funcional objetiva (força de preensão manual, pinça de três pontos, pinça lateral e pinça polpa-a-polpa) e a avaliação funcional subjetiva (DASH, PRWE, EVA) foram avaliadas em 3 momentos diferentes: (1) Antes da cirurgia sem anestesia articular, (2) Antes da cirurgia sob anestesia articular e (3) 12 semanas após o procedimento cirúrgico. Resultados Houve aumento da força de preensão palmar nas três medidas de pinça após o alívio da dor, tanto após a anestesia articular quanto após a consolidação da artrodese (p < 0,05). Nas comparações entre as avaliações subjetivas (DASH, PRWE e VAS), os pacientes tiveram melhores escores na avaliação pós-operatória após 12 semanas (p < 0,05). Não houve diferença estatística ao comparar os valores médios de força encontrados após a anestesia e após 12 semanas de ATP.

Abstract: En | Text: En | PDF: En

Objective: As the older population increases, it is important to identify factors that may reduce the risks of dementia in the general population. One such factor is the concept of cognitive reserve (CR). The present study analyzed the psychometric properties of the Cognitive Reserve Assessment Scale in Health (CRASH) in the Brazilian population. This scale was originally developed to measure CR in individuals with severe mental illness. We also investigated the relationship between the CRASH and clinical or sociodemographic variables. Methods: This study was conducted with 398 individuals. We assessed sociodemographic variables and depression, anxiety, and stress symptoms (Depression, Anxiety and Stress Scale [DASS-21]) using a web-based survey. We constructed a confirmatory factor analysis (CFA) model in order to test the goodness of fit of the factor structure proposed in the original CRASH study. Results: The McDonald’s hierarchical ω for CRASH using CFA parameters was 0.61, and the Cronbach’s alpha coefficient indicated good internal consistency when considering all items (alpha = 0.7). Conclusions: Our results suggest that CRASH can be used to assess CR in the general population in Brazil.

ABSTRACT Introduction: The Band 3 is a red blood cell protein that carries the Dia and Dib antigens from the Diego blood system. The SLC4A1 gene encodes Band 3; Band 3 Memphis is a polymorphism of normal Band 3 and has two variants, but only the variant II carries the Dia antigen. Objectives: Describe the frequencies of the DI*A and DI*B alleles and the Band 3 Memphis among blood donors, sickle cell disease (SCD) patients and Amazonian Indians. Methods: A total of 427 blood samples were collected and separated into three groups: 206 unrelated blood donors, 90 patients with SCD and 131 Amazonian Indians. We performed DI*A/B, normal Band 3 and Band 3 Memphis genotyping, using the Polymerase Chain Reaction Restriction Fragment Length Polymorphism (PCR–RFLP). Results: The frequency of the DI*A/DI*A genotype was 0.5% in blood donors and it was not found in other groups. The frequency of the DI*A/DI*B was higher in Amazonian Indians (33.6%) and the frequency of the DI*B/DI*B was highest in blood donors (92.2%). All 105 individuals tested were positive for the presence of normal Band 3 and of these individuals, only 5/105 (4.8%) presented the Band 3 Memphis mutation. Conclusion: We observed a higher frequency of the DI*B allele in blood donors and a low frequency of the DI*A/DI*A genotype in all groups studied. The Band 3 Memphis was found in a higher frequency in the blood donor group. Our findings highlight the importance of analyzing different population groups to gain a better understanding of the genetic association of blood group antigens.

Abstract Purpose To assess the determinants of the capital structure of Brazilian credit unions. Theoretical framework Capital structure represents one of the central topics in corporate finance theory and decisions about capital structure are among the most important in the strategic management of an organization. Based on the literature on non-financial firms and banks, and further grounded in the trade-off and pecking order theories, determinants that can explain the capital structure of credit unions were selected. Design/methodology/approach The determinants were investigated for 889 Brazilian individual credit unions with information available at the Central Bank of Brazil from 2008 to 2021, totaling 10,132 annual observations, using panel data regression models. Findings Capital structure is negatively influenced by profitability and risk, and positively by size. For tangibility, there is no evident influence. Furthermore, the pecking order theory is more suitable for the case of credit unions. Practical & social implications of research The deepening of knowledge about determinants can help regulatory authorities in the development of public policies that aim to protect credit unions from systemic risk, promoting the growth of the sector, which plays an important role as an agent of social and economic development. Originality/value This study is pioneering in that it presents results indicating that the determinants traditionally considered for non-financial companies and banks are also valid for credit unions, even though they are organizations with different characteristics from the rest.

Abstract Introduction: SARS-CoV-2 infection is characterized by hyperproduction of pro-inflammatory cytokines that impact the cardiovascular system. In addition, several cardiovascular risk factors, like arterial hypertension, were identified as risk factors for greater disease severity and mortality in these patients. The objective of this study is to evaluate the prevalence of hypertension in patients with COVID-19 and its association with complications, comorbidities and mortality. Methods: Retrospective study of the patients with COVID-19 admitted to Internal Medicine ward between March 2020 and February 2021. Data was collected from the digital clinical file. Logistic regression was applied to clarify the effect of independent variables on mortality. Results: The sample included 1291 patients with COVID-19, a median age of 73 years (IQR: 22) and male gender predominance (n = 701, 54.3%). There were 65.5% (n = 845) of patients with hypertension, 54.9% (n = 709) dyslipidemia and about a third had diabetes mellitus and obesity (31 and 38%, respectively). Comparatively to the non-hypertensive patients, hypertensive group presented with higher prevalence of other cardiovascular risk factors (diabetes mellitus, obesity and dyslipidemia (p <0.001)) and lower functionality and more comorbidities (as calculated by AVDezIS and Charlson modified scores, p<0.001). There was also higher proportion of severe COVID-19 disease (p = 0.003), greater number of patients admitted to intensive care units (p <0.001) and higher in-hospital mortality (p <0.001). Hypertension was not a mortality predictive factor in these patients. Conclusion: In this study, patients with hypertension presented with higher severity of COVID-19 disease, higher pre-valence of other cardiovascular risk factors, complications during hospitalization and in-hospital mortality, however, its presence was not a mortality predictive factor.

Resumo Introdução: A infeção por SARS-CoV-2 caracteriza-se por um estado de sobreprodução de citocinas pró-inflamatórias que podem culminar com atingimento cardiovascular. Além disso, vários fatores de risco cardiovascular, como a hipertensão arterial (HTA), têm sido associados a maior severidade e mortalidade na COVID-19. O objetivo deste estudo é avaliar a prevalência da HTA nos doentes com COVID-19 e a sua associação com complicações, comorbilidades e mortalidade. Métodos: Estudo retrospetivo dos doentes admitidos em enfermaria por COVID-19 entre março de 2020 e fevereiro de 2021. Foi realizada colheita de dados através do processo clínico. Aplicada regressão logística para clarificar o efeito de variáveis independentes na mortalidade. Resultados: Incluíram-se 1291 doentes com COVID-19 internados no período descrito, com mediana de idades de 73 anos (AIQ: 22) e predomínio do sexo masculino (n = 701, 54,3%). Observou-se que 65,5% (n = 845) dos doentes tinham HTA, 54,9% (n = 709) dislipidemia e 31% e 38% tinham diabetes mellitus e obesidade, respetivamente. Comparativamente com os indivíduos sem HTA, o grupo com HTA apresentou maior prevalência de fatores de risco cardiovascular (diabetes, obesidade e dislipidemia, p <0,001) bem como menor grau de funcionalidade e maior carga de doença (respetivamente score de AVDezIs e Charlson modificado, p <0,001). Verificou-se uma maior proporção de doença grave (p = 0,003), maior número admissões em Unidade de Cuidados Intensivos (p <0,001) e maior taxa de mortalidade intra-hospitalar (p <0,001). A presença de HTA não se revelou como preditor de mortalidade nos doentes com COVID-19. Conclusão: Nesta amostra os doentes com HTA apresentaram múltiplos fatores de risco cardiovascular, doença COVID-19 mais grave, mais complicações e mortalidade intra-hospitalares, contudo, a sua presença não foi um fator preditor de mortalidade por COVID-19.

ABSTRACT Objective: Intrauterine environment can induce fetal metabolic programming that predisposes to adiposity-related chronic diseases in its lifespan. We examined the associations of parental nutritional status and gestational weight gain with offspring body composition in early adulthood. Materials and methods: This is cross-sectional analysis of female participants of the NutriHS who were submitted to questionnaires, clinical examinations and body composition assessed by DXA. Association of pre-conception parental BMI and maternal gestational weight gain (exposures) with body composition measurements (outcomes) were analyzed using multiple linear models adjusted for Directed Acyclic Graphs-based covariables (maternal and paternal educational level, maternal age, and tobacco, alcohol and/or drugs use). The sample included 124 women (median 28 (24-31) years) with a mean BMI of 25.4 ± 4.7 kg/m2. Results: No association between previous paternal BMI and offspring’s body composition was detected. In the fully adjusted linear regression model, maternal BMI was associated with offspring’s total lean mass (β = 0.66, p = 0.001), appendicular skeletal muscle mass index (ASMI) (β = 0.11, p = 0.003) and fat mass index (FMI) (β = 0.03, p = 0.039). Gestational weight gain was associated with increased offspring’s BMI (OR 1.12 [95% CI 1.02-1.20], p = 0.01). The linear regression model adjusted for maternal age and maternal and paternal education levels showed associations of gestational weight gain with offspring’s ASMI (β = 0.42, p = 0.046), FMI (β = 0.22, p = 0.005) and android-to-gynoid fat ratio (β = 0.09, p = 0.035). Conclusion: Our findings suggest that preconception maternal BMI could influence lean mass and general adiposity of young adult female offspring and that gestational weight gain could be useful for predicting centrally distributed adiposity.

Abstract Background Levodopa is the most used and effective medication for motor symptoms of Parkinson disease (PD), its long-term use is associated with the appearance of levodopa-induced dyskinesia (LID). Uric acid (UA) is believed to play an important neuroprotective role in PD. Objective To investigate if serum UA levels are related with the presence of LIDs in PD patients. Also, we investigated the associations among UA levels and clinical features of PD. Methods We enrolled 81 PD patients (dyskinesia = 48; no dyskinesia = 33) in the present study. A blood sample was collected to evaluate serum UA levels, clinical evaluation included the following instruments: Montreal Cognitive Assessment (MoCA), Beck Depression Inventory II (BDI-II), MDS-Unified Parkinson's Disease Rating Scale (MDS-UPDRS), Hoehn and Yahr (HY), and the sub-item 4.1 of MDS-UPDRS IV (score ≥ 1). Additional relevant clinical information was obtained by a clinical questionnaire. Results Serum UA levels were lower in the dyskinesia group when compared with the no dyskinesia group. The same result was found in the UA levels of both men and women. The multivariate analysis showed lower uric acid levels were significantly associated with having dyskinesia (odds ratio [OR] = 0.424; 95% confidence interval [CI]: 0.221-0.746; p= 0.005). Additional analysis verified that serum UA levels are inversely correlated with depressive symptoms, disease duration, MDS-UPDRS IV and time spent with dyskinesia. A positive correlation was found with age at onset of PD symptoms. Conclusions The present study provides a possible role of serum UA levels in LID present in PD patients.

Resumo Antecedentes A levodopa é a medicação mais utilizada e eficaz para os sintomas motores da doença de Parkinson (DP); seu uso a longo prazo está associado ao aparecimento de discinesia induzida por levodopa (LID). Acredita-se que o ácido úrico desempenhe um importante papel neuroprotetor na DP. Objetivo Investigar se os níveis séricos de AU estão relacionados com a presença de LID em pacientes com DP. Além disso, investigamos as associações entre os níveis de AU e as características clínicas da DP. Métodos Foram incluídos 81 pacientes com DP (discinesia = 48; sem discinesia = 33) no presente estudo. Uma amostra de sangue foi coletada para avaliar os níveis séricos de AU, a avaliação clínica incluiu os seguintes instrumentos: Avaliação Cognitiva de Montreal (MoCA), Inventário de Depressão de Beck (BDI-II), MDS-Unified Parkinson's Disease Rating Scale (MDS-UPDRS), Hoehn and Yahr (HY) e o subitem 4.1 da MDS-UPDRS IV (escore ≥ 1). Informações clínicas relevantes adicionais foram obtidas por meio de um questionário clínico. Resultados Os níveis séricos de AU foram menores no grupo com discinesia quando comparados ao grupo sem discinesia. O mesmo resultado foi encontrado nos níveis de AU de homens e mulheres. A análise multivariada mostrou que níveis mais baixos de ácido úrico foram significativamente associados a ter discinesia (odds ratio [OR] = 0,424; intervalo de confiança (IC) de 95%: 0,221-0,746; p= 0,005). Análises adicionais verificaram que os níveis séricos de AU estão inversamente correlacionados com sintomas depressivos, duração da doença, MDS-UPDRS IV e tempo gasto com discinesia. Uma correlação positiva foi encontrada com a idade de início dos sintomas da DP. Conclusões O presente estudo fornece um possível papel dos níveis séricos de AU na LID presente em pacientes com DP.

ABSTRACT: Enhanced efficiency potassium fertilizers can be a management tool that is crucial to crop sustainability in maize (Zea mays L.). However, there is a need for studies aimed at validating the use of these fertilizers in different production environments. This study aimed to evaluate the performance of maize under sources and rates of K through conventional and enhanced efficiency fertilizers in soil with high available K content. The experiment was carried out for two years in an Oxisol (605 g kg–1 of clay) with high K content (6.7 mmolc dm–3). Three sources were used, one conventional (KCl), one obtained by additives sprayed on the fertilizer surface (KCl-C), and one obtained by compacting KCl powder and adding additives (KCl-CC), associated with three K2O rates as top-dressing (50, 100, 150 kg ha–1) and a control without K2O. In all treatments, 48 kg ha–1 of K2O was applied in the sowing furrow. In the first year, maize yield increased linearly for both the KCl and KCl-C sources. The maximum yield (7,967 kg ha–1) for the KCl-CC was obtained at 88 kg ha–1. In the second year, the maximum yields for the KCl (7,553 kg ha–1) and KCl-C (8,166 kg ha–1) were obtained with 20 and 67 kg ha–1 K2O, respectively, while for the KCl-CC maize yield did not change. Enhanced efficiency K sources promote increases in maize yield ranging from 4.3 % to 7.1 %. Top-dressing K fertilization in high-fertility soils is a viable alternative for producers focused on increasing maize yield, mainly when enhanced efficiency sources are used.

ABSTRACT: This study describes a biotechnological strategy for producing and applying oxalic acid to solubilize phosphorus (P) from rock phosphate (RP). We evaluated six fungal species (Aspergillus niger FS1, Penicillium islandicum FS41, Pleurotus ostreatus PO1, Rhizoctonia solani Rhiz555, Sclerotium rolfsii Sr25, and Sclerotinia sclerotiorum Scl134) and three culture media (potato dextrose broth, Tsao and Strasser media) to maximize oxalic acid production. Among the fungal isolates tested and culture media, S. rolfsii Sr25 and Tsao medium showed efficient oxalic acid production. Tsao medium was optimized following a response surface methodology after initial screening of factors affecting RP solubilization. The optimized concentrations were 1 g L–1 NaNO3, 100 g L–1 glucose, 2 g L–1 KH2PO4, 4.5 g L–1 yeast extract, and 25 mg L–1 MgSO4·7H2O used for 20 days of incubation. Under these conditions, 71 mmol L–1 oxalic acid was obtained, representing a three-fold increase over production under non-optimized conditions (20 mmol L–1). Under optimized conditions, oxalic acid produced by S. rolfsii Sr25 reacted with low-solubility RP and solubilized 100 % of the P contained in ore. Thus, using S. rolfsii Sr25 to produce oxalic acid seems a promising biotechnological alternative for P solubilization from RP.
