Capillary electromigration techniques can be understood as the ones used to separate neutral compounds, solvated ions and ionized species, considering the differentiated migration among them when an electrical field is applied within a capillary column filled with a background electrolyte. Several existing capillary electrophoresis setups provide the possibility of developing reliable quantitative assays of inorganic ions, organic acids, fatty acids, amino acids, carbohydrates, nucleic acids, proteins, hormones, vitamins, macromolecules, and more. Therefore, given the chemical complexity of bodily fluid matrices, capillary electrophoresis (CE) and its variations present themselves as an advantageous strategy for enhancing traditional clinical diagnostic methods and for the development of new ones. The recent advances in the study of the human metabolome associated with technological improvements towards medical applications make CE a very useful and versatile technique for clinical laboratory assays. Within this context, this review has the purpose of presenting some traditional methods used for exams of blood, urine, saliva, feces, and sweat, and how CE can be implemented as a real alternative to enable faster, automated, and cost-effective analysis with a comprehensive perspective that shall result in better diagnostic possibilities for patients, being a powerful tool for helping physicians on the precision medicine achievements. compounds species electrolyte acids carbohydrates proteins hormones vitamins macromolecules more Therefore matrices (CE context blood urine saliva feces sweat faster automated costeffective cost effective patients achievements

ABSTRACT The application of silicon (Si) represents one of the alternatives that can be used to mitigate the deleterious effects caused by salinity on plants in fertigated cultivation. The objective was to evaluate the effect of different levels of water salinity, associated with the use of sodium silicate on the production parameters and nutrient levels in the leaf and stem of mini watermelon in a protected environment. To conduct the experiment, a randomized block design was adopted, in a 6 x 2 factorial scheme, with 4 repetitions, with six levels of irrigation water salinity (1.05; 2.12; 3.26; 4.41; 5.91 and 7.32 dS m-1) and two types of Si application: without Si and in foliar solution. The following parameters were evaluated: plant height, stem diameter, number of leaves, leaf and stem fresh and dry mass; biometric variables and total soluble solids content in the fruits; and nutrient contents in leaves and stem. The use of Si associated with fertigation with different salinity levels promoted a positive response for peel thickness, ºBrix, fresh and dry mass of leaves, and Si accumulation in leaves and stem. Salinity alone promoted an increase in pulp weight, ºBrix of the fruits and potassium content in the stem, besides increasing the manganese content and inhibiting the zinc content in the leaves. There was a significant interaction for the manganese content in the stem, with a positive response in the absence of foliar-applied Si and a negative response in the presence of foliar-applied Si under different levels of salinity.

RESUMO A aplicação de silício (Si) representa uma das alternativas que podem ser utilizadas para mitigar os efeitos deletérios às plantas pela salinidade em cultivo fertirrigado. Objetivou-se avaliar o efeito de diferentes níveis de salinidade da água, associado ao uso de silicato de sódio sobre os parâmetros produtivos e os teores de nutrientes na folha e no caule da mini melancia em ambiente protegido. Para condução do experimento adotou-se delineamento em blocos casualizados, em esquema fatorial 6 x 2, com 4 repetições, sendo seis níveis de salinidade da água de irrigação (1,05; 2,12; 3,26; 4,41; 5,91 e 7,32 dS m-1) e dois tipos de aplicações de silício: sem silício e aplicação em solução via foliar. Foram avaliados: a altura das plantas, diâmetro do caule, número de folhas, peso da matéria fresca e seca de folhas e caule; variáveis biométricas e teor de sólidos solúveis totais nos frutos; e teor de nutrientes nas folhas e caule. O uso do silício associado a fertirrigação com diferentes níveis de salinidade proporcionaram resposta positiva para espessura de casca, ºBrix, massa fresca e seca de folhas e, acúmulo de silício nas folhas e caule. A salinidade isolada proporcionou aumento para peso de polpa, ºBrix dos frutos e teor de potássio no caule e, incrementou o teor de manganês e inibiu teor de zinco nas folhas. Houve interação significativa para o teor de manganês no caule, com resposta positiva na ausência de silício foliar e negativa com aplicação foliar de silício sob diferentes níveis de salinidade.

Abstract Hereditary transthyretin amyloidosis with peripheral neuropathy (ATTRv-PN) is an autosomal dominant inherited sensorimotor and autonomic polyneuropathy with over 130 pathogenic variants identified in the TTR gene. Hereditary transthyretin amyloidosis with peripheral neuropathy is a disabling, progressive and life-threatening genetic condition that leads to death in ~ 10 years if untreated. The prospects for ATTRv-PN have changed in the last decades, as it has become a treatable neuropathy. In addition to liver transplantation, initiated in 1990, there are now at least 3 drugs approved in many countries, including Brazil, and many more are being developed. The first Brazilian consensus on ATTRv-PN was held in the city of Fortaleza, Brazil, in June 2017. Given the new advances in the area over the last 5 years, the Peripheral Neuropathy Scientific Department of the Brazilian Academy of Neurology organized a second edition of the consensus. Each panelist was responsible for reviewing the literature and updating a section of the previous paper. Thereafter, the 18 panelists got together virtually after careful review of the draft, discussed each section of the text, and reached a consensus for the final version of the manuscript.

Resumo Polineuropatia amiloidótica familiar associada a transtirretina (ATTRv-PN) é uma polineuropatia sensitivo-motora e autonômica hereditária autossômica dominante com mais de 130 variantes patogênicas já identificadas no gene TTR. A ATTRv-PN é uma condição genética debilitante, progressiva e que ameaça a vida, levando à morte em ~ 10 anos se não for tratada. Nas últimas décadas, a ATTRv-PN se tornou uma neuropatia tratável. Além do transplante de fígado, iniciado em 1990, temos agora 3 medicamentos modificadores de doença aprovados em muitos países, incluindo o Brasil, e muitas outras medicações estão em desenvolvimento. O primeiro consenso brasileiro em ATTRv-PN foi realizado em Fortaleza em junho de 2017. Devido aos novos avanços nesta área nos últimos 5 anos, o Departamento Científico de Neuropatias Periféricas da Academia Brasileira de Neurologia organizou uma segunda edição do consenso. Cada panelista ficou responsável por rever a literatura e atualizar uma parte do manuscrito. Finalmente, os 18 panelistas se reuniram virtualmente após revisão da primeira versão, discutiram cada parte do artigo e chegaram a um consenso sobre a versão final do manuscrito.

Abstract: En Pt

This guideline aimed to update the concepts and formulate the standards of conduct and scientific evidence that support them, regarding the diagnosis and treatment of the Cardiomyopathy of Chagas disease, with special emphasis on the rationality base that supported it.nbsp; Chagas disease in the 21st century maintains an epidemiological pattern of endemicity in 21 Latin American countries. Researchers and managers from endemic and non-endemic countries point to the need to adopt comprehensive public health policies to effectively control the interhuman transmission of T. cruzi infection, and to obtain an optimized level of care for already infected individuals, focusing on diagnostic and therapeutic opportunistic opportunities. nbsp; Pathogenic and pathophysiological mechanisms of the Cardiomyopathy of Chagas disease were revisited after in-depth updating and the notion that necrosis and fibrosis are stimulated by tissue parasitic persistence and adverse immune reaction, as fundamental mechanisms, assisted by autonomic and microvascular disorders, was well established. Some of them have recently formed potential targets of therapies.nbsp; The natural history of the acute and chronic phases was reviewed, with enhancement for oral transmission, indeterminate form and chronic syndromes. Recent meta-analyses of observational studies have estimated the risk of evolution from acute and indeterminate forms and mortality after chronic cardiomyopathy. Therapeutic approaches applicable to individuals with Indeterminate form of Chagas disease were specifically addressed. All methods to detect structural and/or functional alterations with various cardiac imaging techniques were also reviewed, with recommendations for use in various clinical scenarios. Mortality risk stratification based on the Rassi score, with recent studies of its application, was complemented by methods that detect myocardial fibrosis.nbsp; The current methodology for etiological diagnosis and the consequent implications of trypanonomic treatment deserved a comprehensive and in-depth approach. Also the treatment of patients at risk or with heart failure, arrhythmias and thromboembolic events, based on pharmacological and complementary resources, received special attention. Additional chapters supported the conducts applicable to several special contexts, including t. cruzi/HIV co-infection, risk during surgeries, in pregnant women, in the reactivation of infection after heart transplantation, and others.nbsp; nbsp;nbsp; Finally, two chapters of great social significance, addressing the structuring of specialized services to care for individuals with the Cardiomyopathy of Chagas disease, and reviewing the concepts of severe heart disease and its medical-labor implications completed this guideline.

Esta diretriz teve como objetivo principal atualizar os conceitos e formular as normas de conduta e evidências científicas que as suportam, quanto ao diagnóstico e tratamento da CDC, com especial ênfase na base de racionalidade que a embasou. A DC no século XXI mantém padrão epidemiológico de endemicidade em 21 países da América Latina. Investigadores e gestores de países endêmicos e não endêmicos indigitam a necessidade de se adotarem políticas abrangentes, de saúde pública, para controle eficaz da transmissão inter-humanos da infecção pelo T. cruzi, e obter-se nível otimizado de atendimento aos indivíduos já infectados, com foco em oportunização diagnóstica e terapêutica. Mecanismos patogênicos e fisiopatológicos da CDC foram revisitados após atualização aprofundada e ficou bem consolidada a noção de que necrose e fibrose sejam estimuladas pela persistência parasitária tissular e reação imune adversa, como mecanismos fundamentais, coadjuvados por distúrbios autonômicos e microvasculares. Alguns deles recentemente constituíram alvos potenciais de terapêuticas. A história natural das fases aguda e crônica foi revista, com realce para a transmissão oral, a forma indeterminada e as síndromes crônicas. Metanálises recentes de estudos observacionais estimaram o risco de evolução a partir das formas aguda e indeterminada e de mortalidade após instalação da cardiomiopatia crônica. Condutas terapêuticas aplicáveis aos indivíduos com a FIDC foram abordadas especificamente. Todos os métodos para detectar alterações estruturais e/ou funcionais com variadas técnicas de imageamento cardíaco também foram revisados, com recomendações de uso nos vários cenários clínicos. Estratificação de risco de mortalidade fundamentada no escore de Rassi, com estudos recentes de sua aplicação, foi complementada por métodos que detectam fibrose miocárdica. A metodologia atual para diagnóstico etiológico e as consequentes implicações do tratamento tripanossomicida mereceram enfoque abrangente e aprofundado. Também o tratamento de pacientes em risco ou com insuficiência cardíaca, arritmias e eventos tromboembólicos, baseado em recursos farmacológicos e complementares, recebeu especial atenção. Capítulos suplementares subsidiaram as condutas aplicáveis a diversos contextos especiais, entre eles o da co-infecção por T. cruzi/HIV, risco durante cirurgias, em grávidas, na reativação da infecção após transplante cardíacos, e outros.nbsp;nbsp;nbsp; Por fim, dois capítulos de grande significado social, abordando a estruturação de serviços especializados para atendimento aos indivíduos com a CDC, e revisando os conceitos de cardiopatia grave e suas implicações médico-trabalhistas completaram esta diretriz.nbsp;

Abstract: Pt | Text: Pt | PDF: Pt

The new coronavirus, called Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), was discovered in late December 2019 after cases were reported in the city of Wuhan, China. In January 2020, the World Health Organization (WHO) officially declared the Coronavirus Disease 2019 (COVID-19) as a pandemic, which has an official record of around 500 million cases and more than 6.0 million deaths in worldwide. An important factor in controlling the pandemic is the development of more effective and efficient diagnostic tests. In this context, this review has as its main proposal to discuss the effective differences between the possible diagnostic tests, the implications of molecular and serological methods available on the market and the analytical and clinical parameters involved in the development and application of these methods.

RESUMO Objetivo: Fornecer orientações sobre a frequência e os componentes dos exames oftalmológicos para crianças saudáveis de 0 a 5 anos. Métodos: Essas diretrizes foram desenvolvidas com base em revisão bibliográfica e experiência clínica de um comitê de especialistas. Foram realizadas buscas PubMed/Medline; documentos selecionados não se restringiram a revisões sistemáticas, ensaios clínicos randomizados e estudos observacionais. Quando adequado, o perfil GRADE foi aplicado para graduá-los e o consenso de especialistas foi usado nos tópicos sem evidência científica. Também foram revisadas as recomendações pela Academia Americana de Pediatria, Associação Americana de Oftalmologia Pediátrica e Estrabismo, Academia Americana de Oftalmologia, Royal College of Ophthalmologist e Sociedade Canadense de Oftalmologia. O documento final foi aprovado pela Sociedade Brasileira de Oftalmologia Pediátrica e Sociedade Brasileira de Pediatria. Resultados: Os recém-nascidos devem ser submetidos ao teste do reflexo vermelho e inspeção dos olhos e anexos pelo pediatra dentro de 72 horas de vida ou antes da alta da maternidade. O teste do reflexo vermelho deve ser repetido pelo pediatra durante as consultas de puericultura pelo menos três vezes ao ano durante os primeiros 3 anos de vida. Se factível, um exame oftalmológico completo pode ser feito entre 6 a 12 meses de vida. Até os 36 meses de idade, os marcos visuais, função visual apropriada para a idade, fixação e alinhamento ocular também devem ser avaliados pelo pediatra ou médico da família. Pelo menos um exame oftalmológico completo deve ser realizados entre 3 e 5 anos de idade. O exame deve conter pelo menos inspeção dos olhos e anexos, avaliação da função visual apropriada para a idade, avaliação da motilidade e alinhamento ocular (testes de cobertura), refração sob cicloplegia e avaliação do fundo de olho dilatado. Conclusões: As diretrizes sobre a frequência da avaliação oftalmológica são ferramentas importantes para orientar os médicos sobre a melhor prática a fim de evitar problemas visuais tratáveis na infância, que poderiam comprometer seu desenvolvimento social, escolar e global, além de causar perda permanente da visão.

ABSTRACT Purpose: To provide guidance on the frequency and components of eye examinations for healthy children aged 0 to 5 years. Methods: These guidelines were developed based on the medical literature and clinical experience of an expert committee. PubMed/Medline searches were performed, with selected publications not restricted to systematic reviews, randomized controlled trials, or observational studies. The Grading of Recommendations Assessment, Development, and Evaluation profile was applied when suitable, and for issues without scientific evidence, recommendations were based on expert consensus. Recommendations by the American Academy of Pediatrics, American Association of Pediatric Ophthalmology and Strabismus, American Academy of Ophthalmology, Royal College of Ophthalmologists, and Canadian Ophthalmological Society were also reviewed. The final guideline document was approved by the Brazilian Pediatric Ophthalmology Society and by the Brazilian Pediatric Society. Results: Newborns must undergo the red reflex test and inspection of the eyes and adnexa by a pediatrician within 72 hours of life. The red reflex test should be repeated by the pediatrician during childcare consultations at least three times per year during the first 3 years of life. If feasible, a comprehensive ophthalmologic examination may be performed between 6 and 12 months of age. Until 36 months of age, the pediatrician should assess the infant’s visual development milestones, age-appropriate assessment of visual function, ocular fixation, and eye alignment. At least one comprehensive ophthalmologic examination should be performed at 3 to 5 years of age. The examination should minimally include inspection of the eyes and adnexa, age-appropriate visual function assessment, evaluations of ocular motility and alignment (cover tests), cycloplegic refraction, and dilated fundus. Conclusions: Guidelines concerning the frequency of ophthalmic assessment are important tools for directing physicians regarding best practices that avoid treatable vision problems that affect children’s development, school, and social performance and cause unnecessary permanent vision loss.

OBJECTIVE: In 2020, the COVID-19 pandemic brought a work and stress overload to healthcare workers, increasing their vulnerability to mental health impairments. In response, the authors created the COMVC-19 program. The program offered preventive actions and mental health treatment for the 22,000 workers of The Hospital das Clinicas da Faculdade de Medicina da Universidade de São Paulo (HCFMUSP). This paper aims to describe its implementation and share what we have learned from this experience. METHODS: Workers were able to easily access the program through a 24/7 hotline. Additionally, a mobile phone app that screened for signs and symptoms of emotional distress and offered psychoeducation and/or referral to treatment was made available. Data from both these sources as well as any subsequent psychiatric evaluations were collected. RESULTS: The first 20 weeks of our project revealed that most participants were female, and part of the nursing staff working directly with COVID-19 patients. The most frequently reported symptoms were: anxiety, depression and sleep disturbances. The most common diagnoses were Adjustment, Anxiety, and Mood disorders. CONCLUSIONS: Implementing a mental health program in a multimodal intervention was feasible in a major quaternary public hospital. Our data also suggests that preventive actions should primarily be aimed at anxiety and depression symptoms, with a particular focus on the nursing staff.

RESUMO: Clostridium perfringens é considerado um dos principais agentes causadores de enterocolites superagudas, geralmente fatais na espécie equina, devido à ação da toxina β, além de ser responsável por causar quadros graves de mionecrose, pela ação da toxina α. A grande importância desses agentes na equinocultura, deve-se a elevada mortalidade e a inexistência de vacinas, principal forma de prevenção, que garantam a imunização dessa espécie animal. O objetivo deste trabalho foi avaliar três diferentes concentrações (100, 200 e 400μg) dos toxóides recombinantes α e β de C. perfringens na imunização de equinos, bem como comparar com um grupo vacinado com um toxóide comercial. A vacina comercial não se mostrou capaz de estimular uma resposta imune e a vacina recombinante foi capaz de induzir resposta imune humoral satisfatória em equinos vacinados, provando ser uma alternativa profilática para infecção por C. Perfringens.

ABSTRACT: Clostridium perfringens is considered one of the main causative agents of superacute enterocolitis, usually fatal in the equine species, due to the action of the β toxin, and is responsible for causing severe myonecrosis, by the action of the α toxin. The great importance of this agent in the equine economy is due to high mortality and lack of vaccines, which are the main form of prevention, which guarantee the immunization of this animal species. The aim of this study was to evaluate three different concentrations (100, 200 and 400μg) of C. perfringens α and β recombinant toxoids in equine immunization and to compare with a group vaccinated with a commercial toxoid. The commercial vaccine was not able to stimulate an immune response and the recombinant vaccine was able to induce satisfactory humoral immune response in vaccinated horses, proving to be an alternative prophylactic for C. perfringens infection.

RESUMO A brusone do trigo, causada pelo fungo Magnaporthe oryzae, está entre os fatores que apresenta maior risco na produção de trigo, pois os danos podem ser superiores a 90% em safras com condições ambientais favoráveis ao desenvolvimento da doença. O objetivo do trabalho foi avaliar o efeito de sulfato de zinco sobre a severidade de M. oryzae em folhas de trigo, a produção de peróxido de hidrogênio e de morte celular da planta. Avaliou-se a severidade da doença em função da aplicação foliar de Zn (0; 0,4; 0,8; 1,2 e 1,6% de sulfato de zinco) em diferentes cultivares de trigo (Mirante, Safira, Madre Pérola e Ônix). Além disso, com objetivo de verificar qual possível componente histológico está envolvido na redução da severidade da brusone, realizou-se um experimento com aplicação de sulfato de zinco a 0,4% na 3ª folha e sem aplicação (água destilada) na cultivar de trigo Safira, que é suscetível a essa doença. Três dias após a aplicação de ZnSO4, as plantas foram inoculadas com suspensão de 104 conídios.mL-1 de M. oryzae e mantidas em câmara úmida durante 24 h, procedendo-se a coleta das folhas às 18; 24; 30; 36; 48 e 72 horas após a inoculação (hai). As folhas foram fragmentadas e clareadas a fim de avaliações histopatológicas, para as respostas de produção de peróxido de hidrogênio e morte celular, durante a infecção de trigo por M. oryzae. Houve redução de severidade da brusone quando aplicado zinco em diferentes concentrações nas cultivares, com exceção da cultivar Ônix. O zinco 0,4% não teve efeito nos eventos de infecção, com exceção de morte celular 48 hai. Cultivar de trigo e concentrações de sulfato de zinco influenciam na eficiência da redução da severidade da doença.

ABSTRACT Wheat blast, caused by the fungus Magnaporthe oryzae, is among the factors of highest risk for wheat production because losses can be greater than 90% in crop seasons with favorable environmental conditions to the development of this disease. The objective of this study was to evaluate the effect of zinc sulfate on M. oryzae infection in wheat leaves, as well as hydrogen peroxide production and cell death in the plant. The disease severity was evaluated as a function of foliar application of Zn (0, 0.4%, 0.8%, 1.2% and 1.6% zinc sulfate) in four different wheat cultivars (‘Mirante’, ‘Safira’, ‘Madre Pérola’ and ‘Ônix’). In addition, with the aim of verifying which histological component is possibly involved in reducing blast severity, an experiment was carried out with application of 0.4% zinc sulfate onto the 3rd leaf and without application (distilled water) in the cultivar ‘Safira’, which is susceptible to this disease. Three days after ZnSO4 application, the plants were inoculated with 104 conidia.mL-1 suspension of M. oryzae and kept in a humid chamber during 24 h; leaves were collected at 18, 24, 30, 36, 48 and 72 hours after inoculation (hai). The leaves were fragmented and bleached for histopathological evaluations of the responses of hydrogen peroxide production and cell death during wheat infection by M. oryzae. Wheat blast severity reduced when zinc was applied at different concentrations in all cultivars, except ‘Onyx’. Zinc at 0.4% had no effect on infection events, except for cell death at 48 hai. The wheat cultivar and the zinc sulfate concentrations influenced the disease severity reduction efficiency.

RESUMO O tomate é amplamente cultivado em todo o mundo e requer polinização por abelhas nativas ou manejadas para realizar o pleno potencial de produção dos frutos. Para investigar a riqueza e abundância de espécies de abelhas nativas em plantações de tomate do Centro-Oeste do Brasil, dois métodos de amostragem (armadilhas pan-trap e amostragem ativa) foram utilizados em nove propriedades de junho a setembro de 2011. Um total de 465 indivíduos de 44 espécies foi coletado. A composição das espécies de abelhas amostradas diferiu dependendo do método utilizado. Vinte e duas espécies foram capturadas exclusivamente em armadilhas, 13 outras por meio de amostragem ativa e nove por ambos os métodos. A maioria das espécies de abelhas capturadas neste estudo pode ser considerada polinizadores eficazes do tomate, porque elas podem executar a polinização por vibração. Vibrando seus músculos torácicos, essas abelhas podem liberar o pólen das anteras para seus próprios corpos e para os estigmas da mesma flor, uma vez que eles estão dentro do cone de anteras da variedade do tomate estudado. Ambos os métodos amostraram espécies exclusivas de abelhas vibradoras. No entanto, as armadilhas capturaram abelhas vibradoras e não vibradoras indiscriminadamente e o método ativo amostrou principalmente a abelha vibradora. As coletas utilizando armadilhas e amostragens ativas foram complementares. O uso de apenas um método de amostragem não fornece um entendimento completo da riqueza de espécies de polinizadores de tomate no campo.

ABSTRACT The tomato is widely cultivated throughout the world and requires pollination by wild or managed bees to realize its full-potential fruit production. Two different sampling methods (pan trapping and active sampling) were employed in nine different properties from June to September of 2011 to investigate the richness and abundance of native bee species present in tomato crops of Center-West Brazil. A total of 465 individuals of 44 species were collected, with the composition of sampled bee species differing between the methods used. Twenty-two species were exclusively captured in pan traps, 13 others through active sampling and nine by both methods. Most of the sampled bee species can be considered effective pollinators of the tomato because they can perform buzz-pollination. By vibration, these bees can liberate pollen from anthers into the air or onto their own bodies and the stigmas of the same flower because the stigmas of the studied tomato variety are within the anther cone. Both methods exclusively sampled some species of buzz-pollinating bees, however, pan-trapping captured buzzing and non-buzzing visitors indiscriminately while active sampling captured more buzzing bees. Pan-trapping and active sampling appear to complement each other, and so the use of only one or the other would not provide a full understanding of the species richness of tomato pollinators in the field.

ABSTRACT Objective: Hypoparathyroidism is characterized by parathyroid hormone deficiency and hypocalcemia. It has been demonstrated that these patients may also present psychiatric symptoms and decrease of quality of life. The aims of this study were to evaluate the presence of psychopathological symptoms in a cohort of patients with hypoparathyroidism and compare to a control group. Subjects and methods: Patients were submitted to a cross-sectional Symptom Checklist-90-R (SCL-90-R) questionnaire that evaluates psychopathological symptoms by means of the Global Severity Index (GSI), Positive Symptoms Total (PST) and Positive Symptom Distress Index (PSDI). A score based in the positive symptoms was calculated (T-score). The test group was composed of patients with hypoparathyroidism, and control by thyroidectomized patients without hypoparathyroidism. A correlation between the presence of psychological symptoms and clinical features was analyzed. Results: The study included 57 patients with a mean age of 51.1 ± 16.4 years; 20 as a control and 37, test group. There were no differences between groups regarding gender, mean age and age at diagnose. Hypoparathyroidism patients presented higher GSI index than the control group (p = 0.038). Mean T-score of the test group was as elevated as 58.2 ± 5.3 (reference range < 55). No correlation of the number of psychological symptoms to clinical and laboratorial parameters was observed. Conclusion: Patients with hypoparathyroidism attending our outpatient clinics presented an increase in the number of self-report of psychological symptoms when compared with a control group. However, no correlation with hypocalcemia and clinical parameters was observed. Future studies are necessary to evaluated if the absence of PTH play a role on it.

RESUMO A substituição da vegetação natural pela agricultura impacta diretamente as frações da matéria orgânica no solo. Este estudo avaliou os teores de carbono orgânico total (COT) e nitrogênio total (NT) nas frações da matéria orgânica do solo (MOS) em um Latossolo do semiárido brasileiro sob diferentes sistemas de manejo com diferentes culturas irrigadas. Os sete tratamentos foram compostos por dois sistemas de manejo do solo (plantio direto e convencional) e três culturas: sorgo, girassol e milho tendo como referência o solo sob mata nativa (MN). A semeadura das culturas no verão precedeu a semeadura de feijão no outono/inverno. Após dois anos e três meses de implantação, avaliaram-se os teores de carbono orgânico total, nitrogênio total, teor de carbono nas substâncias húmicas e seus constituintes (fração ácidos fúlvicos, húmicos e humina), teores de carbono lábil, carbono não-lábil e carbono solúvel em água, sendo determinados a labilidade (L), índice de labilidade (IL), índice de compartimento de carbono (ICC) e índice de manejo de carbono (IMC). Os cultivos sob sistema de plantio direto (SPD) nas condições semiáridas, em especial com o milho, promoveram maiores teores de carbono, nitrogênio e frações da matéria orgânica, na camada superficial do solo (0,00 a 0,05 m). Na camada de 0,05-0,10 m os cultivos sob SPD promoveram aumento nos teores de carbono nas substâncias húmicas, em comparação aos SPC. Maior sustentabilidade foi observada nos cultivos em SPD no semiárido, em relação àqueles sob SPC, indicado pelos maiores IMC na camada superficial do solo sob SPD.

ABSTRACT The replacement of natural vegetation by crop systems directly impacts the soil organic matter fractions. The objective of this study was to evaluate the total organic carbon (TOC) and nitrogen (TN) contents in different fractions of the soil organic matter (SOM) of an Oxisol of the Brazilian semiarid region under different irrigated crops and different soil management systems. Seven treatments were evaluated, which consisted of two soil management systems (no-till and conventional tillage) and three crops (maize, sunflower and sorghum), using as reference the soil under a native forest (NF). The summer crops preceded common bean crops in the autumn-winter. The total organic carbon content, total nitrogen, carbon content in humic substances and their constituents (fulvic acids, humic acids and humin) and labile, non-labile and water-soluble carbon contents were evaluated two years and three months after the experiment implementation to determine the carbon lability (L) lability index (LI), partitioning index (CPI) and management index (CMI). The greatest carbon, nitrogen and organic matter contents in the soil surface layer (0.00-0.05 m) were found in crops under no-till system (NTS), especially maize. The crops under NTS presented greater carbon content in humic substances than the conventional tillage system (CTS) ones in the layer 0.05-0.10 m. The crops under NTS presented greater sustainability in the Brazilian semiarid region compared with those under CTS, as shown by their higher CMI in the soil surface layer.

RESUMO Foi avaliada a qualidade física de um Latossolo Vermelho-Amarelo de textura franco-argilo-arenosa do semiárido, cultivado nos sistemas de plantio direto (SPD) e preparo convencional (SPC) com diferentes coberturas vegetais. O experimento foi implantado como parcela única (18 x 18 m) para cada um dos seis tratamentos: dois sistemas de cultivo e três culturas (milho, girassol e sorgo) semeadas no verão, precedentes ao feijão, semeado no outono/inverno, além da mata nativa (MN) como testemunha. Avaliou-se a cobertura morta na superfície do solo, resistência do solo à penetração, carbono orgânico total, estabilidade de agregados em água, densidade do solo, macroporos, microporos, porosidade total e retenção de água nas profundidades 0,00-0,05; 0,05-0,10; 0,10-0,20 e 0,20-0,40 m. Os melhores indicadores físicos de qualidade do solo nas condições do semiárido foram obtidos no solo sob plantio direto com gramíneas. O SPD mantém a agregação do solo semelhante à MN, enquanto o SPC reduz a agregação e o aporte de carbono no solo. As gramíneas no SPD incrementam o teor de carbono no solo, devido à maior produção de cobertura morta em relação ao girassol. O SPD causa maior compactação superficial do solo que o SPC, mas não altera a retenção de água. Os tratamentos não influenciaram nenhum dos atributos na profundidade de 0,20-0,40 m.

ABSTRACT An evaluation was made of the physical quality of a sand-clay Red-Yellow Latosol loam in the semi-arid region, cultivated under no-tillage (SPD) and conventional tillage (SPC) systems under different soil cover. The experiment was set up in a single plot (18 x 18 m) for each of the six treatments: two cropping systems and three crops (maize, sunflower and sorghum) planted in the summer, ahead of the beans sown in the autumn/winter, with the native forest (MN) as control. Litter on the soil surface, soil penetration resistance, total organic carbon, aggregate stability in water, soil bulk density, macropores, micropores, total porosity and water retention were evaluated at depths of 0.00 to 0.05, 0.05 to 0.10, 0.10 to 0.20 and 0.20 to 0.40 m. The best physical indicators of soil quality under semi-arid conditions were found in the soil under no-tillage and grass. No-tillage keeps soil aggregation at a level similar to that of MN, whereas under conventional tillage, aggregation and carbon input are reduced in the soil. Grasses under no-tillage increase the carbon content of the soil, due to a greater production of litter compared to the sunflower. No-tillage causes greater surface soil compaction than conventional tillage but has no effect on water retention. The treatments had no effect on any of the attributes at the depth of 0.20 to 0.40 m.
