ABSTRACT Objective: To report and compare the results of posterior cruciate ligament (PCL) and anterior cruciate ligament (ACL) reconstructions. Methods: In total, 42 patients were retrospectively evaluated, 20 with isolated PCL injuries (group 1) and 22 with isolated ACL ones (group 2) who were subjected to arthroscopic ligament reconstruction with autologous grafts and followed up for at least two years. To evaluate the results in group 1, objective IKDC and Lysholm scores, posterior drawer tests, and evaluations by a KT-1000 arthrometer were used, whereas for group 2, subjective IKDC and Lysholm score and the Lachman test were employed. To compare groups, objective IKDC and Lysholm scores and assessment via a KT-1000 arthrometer were considered. Results: Intragroup analysis showed improved results for all variables (p < 0.001) in both groups. Comparisons between groups showed a significant difference in objective IKDC scores (p < 0.001), but no such disparities for Lysholm ones (p = 0.052), clinical tests (p = 0.058) or evaluation by KT-1000 (p = 0.129). Conclusion: Treatment restored knee stability and function in both groups. Comparisons between groups showed that PCL reconstructions had inferior results than ACL ones according to patients’ objective IKDC scores. Level of Evidence II, Retrospective Study.

RESUMO Objetivo: Reportar e comparar os resultados da reconstrução do ligamento cruzado posterior (LCP) e do ligamento cruzado anterior (LCA). Métodos: Foram avaliados retrospectivamente 42 pacientes: 20 com lesão isolada do LCP (grupo 1) e 22 com lesão isolada do LCA (grupo 2), submetidos à reconstrução ligamentar artroscópica com enxertos autólogos e acompanhados por pelo menos dois anos. Para avaliação dos resultados no grupo 1, foram utilizados o escore do International Knee Documentation Committee (IKDC) objetivo, escore de Lysholm, teste da gaveta posterior e avaliação pelo artrômetro KT-1000; e, para o grupo 2, foram utilizados o IKDC subjetivo, escore Lysholm e teste de Lachman. Para comparação entre os grupos, foram considerados o IKDC objetivo, escore Lysholm e avaliação pelo artrômetro KT-1000. Resultados: Ambos os grupos demonstraram melhora dos resultados na análise intragrupo em todas as variáveis (p < 0,001). Na comparação intergrupos, observou-se diferença significativa no IKDC objetivo (p < 0,001), não sendo observada diferença no escore Lysholm (p = 0,052), nos testes clínicos (p = 0,058) ou na avaliação pelo KT-1000 (p = 0,129). Conclusão: A estabilidade e função do joelho foram restauradas em ambos os grupos. Na comparação intergrupos, a reconstrução do LCP apresentou resultados inferiores à reconstrução do LCA no critério IKDC objetivo. Nível de Evidência II, Estudo Retrospectivo.

ABSTRACT Objective: To determine the frequency of reoperations in the treatment of adult patients diagnosed with septic arthritis of the knee, the average number of debridements needed to control the infection, the mortality rate, and to assess factors associated with a greater need for reoperation and mortality. Methods: Retrospective cohort study evaluating 38 adult patients diagnosed with septic arthritis who underwent arthrotomy via a medial parapatellar approach for joint cleaning and debridement. Demographic, clinical, surgical, and microbiological variables of the cases were analyzed by review of medical records. Tests for equality of two proportions, chi-square, and multivariate logistic regression analysis were performed, defining a significance level at 0.05, with 95% confidence interval. Results: A total of 50% of the cases underwent reoperation, with an average number of required debridement of 2.02 and a mortality rate of 10.5%. Patients with infection caused by Staphylococcus aureus were more likely to need a reoperation compared to patients with positive cultures for other agents (OR 6.0). Conclusion: In 50% of cases, an average of 2.02 debridements were necessary and the mortality rate was 10.5%. Staphylococcus aureus infection is associated with a 6 times greater chance of additional surgeries. /Level of Evidence IV, Case Series.

RESUMO Objetivo: Determinar a frequência de reabordagens cirúrgicas no tratamento de pacientes adultos com diagnóstico de artrite séptica do joelho, a média de desbridamentos necessários para o controle da infecção e a taxa de mortalidade, assim como avaliar os fatores associados à maior necessidade de reabordagem e mortalidade. Métodos: Estudo retrospectivo tipo coorte que avaliou 38 pacientes adultos com diagnóstico de artrite séptica submetidos à artrotomia por via parapatelar medial para limpeza e desbridamento da articulação. Foram analisadas variáveis demográficas, clínicas, cirúrgicas e microbiológicas dos casos, por revisão de prontuário médico, e realizados testes de igualdade de duas proporções, qui-quadrado e análise multivariada de regressão logística, sendo definido um nível de significância de 0,05, com 95% de confiança estatística. Resultados: 50% dos casos foram submetidos à reabordagem cirúrgica, sendo a média de desbridamentos necessários de 2,02 e a taxa de mortalidade de 10,5%. Pacientes com infecção causada por Staphylococcus aureus apresentaram mais chances de necessitar de reabordagem quando comparados aos pacientes com culturas positivas para outros agentes (OR 6,0). Conclusão: Em 50% dos casos foram necessários, em média, 2,02 desbridamentos e a taxa de mortalidade foi de 10,5%. A infecção por Staphylococcus aureus está associada com seis vezes mais chances de cirurgias adicionais. Nível de Evidência IV, Série de Casos.

Abstract Objective To evaluate clinical characteristics and outcomes of COVID-19 patients infected with HIV, and to compare with a paired sample without HIV infection. Methods This is a substudy of a Brazilian multicentric cohort that comprised two periods (2020 and 2021). Data was obtained through the retrospective review of medical records. Primary outcomes were admission to the intensive care unit, invasive mechanical ventilation, and death. Patients with HIV and controls were matched for age, sex, number of comorbidities, and hospital of origin using the technique of propensity score matching (up to 4:1). They were compared using the Chi-Square or Fisher's Exact tests for categorical variables and the Wilcoxon for numerical variables. Results Throughout the study, 17,101 COVID-19 patients were hospitalized, and 130 (0.76%) of those were infected with HIV. The median age was 54 (IQR: 43.0;64.0) years in 2020 and 53 (IQR: 46.0;63.5) years in 2021, with a predominance of females in both periods. People Living with HIV (PLHIV) and their controls showed similar prevalence for admission to the ICU and invasive mechanical ventilation requirement in the two periods, with no significant differences. In 2020, in-hospital mortality was higher in the PLHIV compared to the controls (27.9% vs. 17.7%; p = 0.049), but there was no difference in mortality between groups in 2021 (25.0% vs. 25.1%; p > 0.999). Conclusions Our results reiterate that PLHIV were at higher risk of COVID-19 mortality in the early stages of the pandemic, however, this finding did not sustain in 2021, when the mortality rate is similar to the control group.

Abstract Introduction Periodontal treatment involves procedures aimed to reduce bacterial load, involving or not the use of local or systemic antibiotics. Objective The purpose of this study was to assess Brazilian dentists’ knowledge about antibiotics prescription during periodontal treatment. Material and method An online questionnaire was available asking for systemic application of local or systemic antibiotics prescription (frequency, and sequence with mechanical periodontal treatment) and in relation to different periodontal diseases. The use of microbial diagnostic services and volunteers’ demographic data were also elucidated. Data were statistically analyzed (Binomial Test, p<0.05). Result Three hundred and ninety-three volunteers answered the questionnaire. Twenty-three percent males and 76.2% females. Average age was 27.7 years. Minority (19.2%) of the volunteers reported to indicate systemic antibiotics to treat gingivitis or periodontitis stages I and II (old slight and moderate chronic periodontitis). Majority of the professionals indicate it to treat periodontal abscess, necrotizing ulcerative gingivitis or periodontitis, periodontitis in severe immunodeficiencies, old aggressive periodontitis, and periodontitis stages III and IV (old severe chronic periodontitis). Rarely (2.5%) the prescription was without the combination with mechanical therapy. Microbiological tests as an auxiliary diagnostic method are rarely (3.1%) requested due to lack of information or cost. Most frequent answers about the number of times professionals reported prescribing systemic antibiotics as part of periodontal treatment per trimester was “at least once”, followed by “2 times”. Conclusion It can be concluded that Brazilian dentists have knowledge about the correct prescription of antibiotics in periodontal therapy.

Resumo Introdução O tratamento periodontal envolve procedimentos que visam reduzir a carga bacteriana, envolvendo ou não o uso de antibióticos locais ou sistêmicos. Objetivo O objetivo deste estudo foi avaliar o conhecimento dos cirurgiões-dentistas brasileiros sobre a prescrição de antibióticos durante o tratamento periodontal. Material e método Foi disponibilizado um questionário online solicitando aplicação sistêmica de prescrição de antibióticos locais ou sistêmicos (frequência e sequência com tratamento periodontal mecânico) e em relação a diferentes doenças periodontais. A utilização de serviços de diagnóstico microbiano e dados demográficos dos voluntários também foram elucidados. Os dados foram analisados estatisticamente (Teste Binomial, p<0,05). Resultado Trezentos e noventa e três voluntários responderam ao questionário. Vinte e três por cento do sexo masculino e 76,2% do sexo feminino. A idade média foi de 27,7 anos. A minoria (19,2%) dos voluntários relatou indicar antibióticos sistêmicos para tratamento de gengivite ou periodontite estágios I e II (antiga periodontite crônica leve e moderada). A maioria dos profissionais indica para tratar abscesso periodontal, gengivite ou periodontite ulcerativa necrosante, periodontite em imunodeficiências graves, periodontite agressiva antiga e periodontite estágios III e IV (periodontite crônica grave antiga). Raramente (2,5%) a prescrição foi sem a associação com terapia mecânica. Os exames microbiológicos como método auxiliar de diagnóstico raramente (3,1%) são solicitados por falta de informação ou custo. As respostas mais frequentes sobre o número de vezes que os profissionais relataram prescrever antibióticos sistêmicos como parte do tratamento periodontal por trimestre foram “pelo menos uma vez”, seguido de “2 vezes”. Conclusão Pode-se concluir que os cirurgiões-dentistas brasileiros possuem conhecimento sobre a correta prescrição de antibióticos na terapia periodontal.

Abstract Introduction The number of stimuli is important to determine the quality of auditory evoked potential records. However, there is no consensus on that number in studies, especially in the sample studied. Objectives To investigate the influence of the number of rare stimuli on forming N2 and P3 components, with different types of acoustic stimuli. Methods Cross-sectional, descriptive, comparative study, approved by the ethics committee of the institution. The sample comprised 20 normal hearing adults of both sexes, aged 18 to 29 years old, with normal scores in the mental state examination and auditory processing skills. The event-related auditory evoked potentials were performed with nonverbal (1 kHz versus 2 kHz) and verbal stimuli (/BA/ versus /DA/). The number of rare stimuli varied randomly in the recordings, with 10, 20, 30, 40, and 50 presentations. Results P3 latency was significantly higher for nonverbal stimuli with 50 rare stimuli. N2 latency did not show any difference between the type and number of stimuli. The absolute P3 and N2-P3 amplitudes showed significant differences for both types of stimuli, with higher amplitude for 10 rare stimuli, in contrast with the other ones. The linear tendency test indicated significance only for the amplitude – as the number of rare stimuli increased, the amplitude tended to decrease. Conclusion The components were identifiable in the different numbers of rare stimuli and types of stimuli. The P3 and N2-P3 latency and amplitude increased with fewer verbal and nonverbal stimuli. Recording protocols must consider the number of rare stimuli.

Abstract Intense soil preparation and disturbance in crops, over time, reduces the quantity and quality of soil organic matter. Given this context, this work aimed to determine soil carbon stocks and labile fractions under agroforestry system (AFS) and toposequences in an altitude marsh, Taquaritinga do Norte, Pernambuco, Brazil. The study was carried out at the Yaguara farm, and the areas studied were native forest with 4.57 ha and coffee plantation in shade with native forest with 25.59 ha. Soil samples were collected in four trenches measuring 1.5 x 1.5 x 0.60 m, with a distance of 50 meters. Soils were collected at depths of 0-20, 20-40 and 40-60 cm, followed by chemical, physical and density analyzes to determine soil carbon stocks and labile fractions. The area with shaded coffee showed higher values of soil carbon stocks at depths of 0-20 cm and 20-40 cm. At a depth of 40-60 cm, the AFS top toposequence showed the highest carbon stock with 11.73 Mg ha-1, followed by the area with native vegetation with 10.6 Mg ha-1, slope with 9.23 Mg ha-1 and pediment with 7.00 Mg ha-1. It was found that the top toposequence with shaded coffee exhibited a greater stock of labile carbon at depth 0-20 cm with a value of 1.06 Mg ha-1, followed by the bedding areas (SAF) with 0.88 Mg ha-1, native forest with 0.79 Mg ha-1 and slope with 0.67 g kg-1. However, the area of native vegetation showed the highest value of labile carbon at a depth of 40-60 cm. It was concluded that the area with shaded coffee in the top toposequence showed great capacity to increase total carbon stocks and labile carbon stocks of soil organic matter.

Resumo O intenso preparo e revolvimento do solo em cultivos, com o tempo, reduz a quantidade e a qualidade da matéria orgânica do solo. Diante desse contexto, este trabalho teve como objetivo determinar os estoques de carbono do solo e frações lábeis sob sistema agroflorestal (SAF) e topossequências em brejo de altitude, em Taquaritinga do Norte, Pernambuco, Brasil. O estudo foi desenvolvido na fazenda Yaguara, e as áreas estudadas foram mata nativa com 4,57 ha e plantio de café sombreado com mata nativa com 25,59 ha. As amostras de solos foram coletadas em quatro trincheiras 1,5 x 1,5 x 0,60 m, com distância de 50 metros. Foram coletados solos nas profundidades de 0-20, 20-40 e 40-60 cm, seguido de análises químicas, físicas e densidade para determinação dos estoques de carbono no solo e frações lábeis. A área com café sombreado apresentou maiores valores de estoques de carbono no solo nas profundidades de 0-20 cm e 20-40 cm. Na profundidade de 40-60 cm, a topossequência de topo do SAF apresentou maior estoque de carbono com 11,73 Mg ha-1, seguido da área com vegetação nativa com 10,6 Mg ha-1 , encosta com 9,23 Mg ha-1 e pedimento com 7,00 Mg ha-1. Verificou-se que a topossequência de topo com café sombreado exibiu maior estoque de carbono lábil na profundidade 0-20 cm com o valor de 1,06 Mg ha-1, sucedido das áreas de pedimento (SAF) com 0,88 Mg ha-1, mata nativa com 0,79 Mg ha-1e encosta com 0,67 Mg ha-1. No entanto, a área de vegetação nativa apresentou o maior valor de carbono lábil na profundidade de 40-60 cm. Concluiu-se que a área com café sombreado na topossequência topo mostrou grande capacidade para elevar os estoques de carbono total e estoques de carbono lábil da matéria orgânica do solo.

Resumo: O Programa Arborização Urbana: Um Exercício de Cidadania e Sustentabilidade Socioambiental, da Universidade Federal do Pampa (UNIPAMPA), na cidade de Bagé, RS, desenvolveu um projeto voltado para o uso de Tecnologias de Informação e Comunicação (TIC) e acessibilidade, que agregou o contexto de inclusão social ao trabalho de identificação de árvores de praças da cidade. A base para este trabalho foi o Inventário Arbóreo das Principais Ruas e Praças da Cidade de Bagé, RS, realizado no período de 2014 a 2016, de forma voluntária por insttuições de ensino e voluntários da comunidade. Dada a relevância do tema da inclusão social, foram desenvolvidas ferramentas voltadas ao atendimento das necessidades especiais, objetivando a interação de grupos com deficiência auditiva e visual com as informações levantadas no inventário arbóreo, sobre as espécies ocorrentes na Praça do Coreto, localizada na região central da cidade. Foram utilizando placas contendo QR Codes que direcionam o leitor a vídeos na Língua Brasileira de Sinais (LIBRAS), para o acesso de deficientes auditivos, e placa central, com recursos em Braile, para o acesso de deficientes visuais, visando popularizar os dados científicos do inventário arbóreo e ampliar o alcance do trabalho de Educação Ambiental para outros grupos da sociedade sem oportunidade de acessar informações sobre a arborização urbana.

Abstract: The Urban Forestry Program: An Exercise of Citizenship and Socio-Environmental Sustainability, from the Federal University of Pampa (UNIPAMPA), in the city of Bagé, RS, developed a project aimed at the use of Information and Communication Technologies (ICT) and accessibility, which added the context of social inclusion to the work of identifying trees in the city’s squares. The basis for this work was the Arboreal Inventory of the Main Streets and Squares of the City of Bagé, RS, carried out from 2014 to 2016, voluntarily, by educational institutions and community volunteers. Given the relevance of the social inclusion theme, tools were developed focusing to meeting special needs, aimed at the interaction of groups with hearing and visual impairments with the information collected in the arboreal inventory, about the species occurring in the Praça do Coreto, located in the central region of the city. Plates containing QR Codes were used to direct the reader to videos in Brazilian Sign Language (LIBRAS) – for the access of the hearing impaired – and a central plate with resources in Braille – for the access of the visually impaired –, aiming to popularize the scientific data of the arboreal inventory and expand the reach of the Environmental Education work for other groups in society with no opportunity to access information about urban forestry.

Abstract: En | Text: En | PDF: En

The control of fungal species in agriculture is mainly conducted with the use of contact or systemic fungicides. However, environmental and human health concerns and increased resistance of fungal species to existing fungicides have increased the pressure on researchers to find new active ingredients for fungal control which present low toxicity to non-target organisms, are environmentally safe, and can be applied at very low concentrations. It is herein described the synthesis of eleven glycerol triazole containing compounds (ten of them fluorinated derivatives) and evaluation of their fungicidal activity. Eight out of eleven synthesized compounds are novel and all of the glycerol derivatives were characterized using infrared (IR), nuclear magnetic ressonance (NMR), and mass spectrometry (MS) techniques. Theoretical calculations were also carried out and the results are discussed. Starting from glycerol, the triazole derivatives were prepared in four steps. Evaluation of them against Colletrotricum gloesporioides showed that compound 1-((2,2-dimethyl-1,3 dioxolan-4-yl)methyl)-4-(2-fluorophenyl)-1H-1,2,3-triazole (4d) (ED50 = 59.14 µg mL-1) was slightly more active than commercial fungicide tebuconazole (61.35 µg mL-1). Compound 4d presented attractive physicochemical features for agrochemical purposes as revealed by the calculated physicochemical parameters. It is believed that glycerol-fluorinated triazole derivatives can be explored towards the development of new chemicals for the control of fungal species.

Abstract Background Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease that affects the upper and lower motor neurons. The correct diagnosis at the onset of the disease is sometimes very difficult, due to the symptoms being very similar to those of other neurological syndromes. Objective This study aimed to analyze the initial manifestations, the specialty of the first physician visited due the initial complaint, the misdiagnoses, as well as the unnecessary surgical interventions in a new ALS Brazilian population. Methods The medical records of 173 patients with typical ALS were reviewed. Results The present study demonstrated that other symptoms, besides weakness, were very frequent as initial presentation of ALS, and orthopedics was the medical specialty most sought by patients at the onset of symptoms. Our frequency of misdiagnoses was 69.7%, and in 7.1% of them, an unnecessary surgical intervention was performed. Conclusions Amyotrophic lateral sclerosis presents a very large pool of signs and symptoms; therefore, there is an urgent need of increasing the disease awareness to other specialties due to the high frequency of misdiagnoses observed in clinical practice.

Resumo Antecedentes A esclerose lateral amiotrófica (ELA) é uma doença neurodegenerativa que afeta os neurônios motores superior e inferior. O diagnóstico correto no início da doença é, às vezes, muito difícil, pois os sintomas de início são muito semelhantes aos de outras síndromes neurológicas. Objetivo Este estudo teve como objetivo analisar as manifestações iniciais, a especialidade do primeiro médico visitado devido à queixa inicial, os diagnósticos errôneos, bem como as intervenções cirúrgicas desnecessárias em uma nova população brasileira acometida por ELA. Métodos Os prontuários médicos de 173 pacientes com ELA típica foram revisados. Resultados O presente estudo demonstrou que outros sintomas, além da fraqueza, foram muito frequentes como apresentação inicial da ELA, sendo a ortopedia a especialidade médica mais procurada pelos pacientes no início dos sintomas. Nossa frequência de diagnósticos errôneos foi de 69,7%, e em 7,1% deles foi realizada intervenção cirúrgica desnecessária. Conclusões A ELA apresenta um conjunto amplo de sinais e sintomas; portanto, há necessidade urgente de uma melhor educação de outras especialidades devido à alta frequência de diagnósticos equivocados observada na prática clínica.

Abstract Background Cardiotoxicity is the main complication related to cancer therapy. Studies indicate that global longitudinal strain is an early detector of subclinical dysfunction of the left ventricle, preceding the decline in ejection fraction (EF). However, the reproducibility of such methodology has not been tested outside specialized centers. Objectives To assess the frequency of subclinical cardiotoxicity and to compare global longitudinal strain and EF measurements during the clinical course of patients undergoing chemotherapy for breast cancer. Methods This was an observational prospective study of 78 adult women who underwent serial echocardiograms (baseline and 1, 3, and 6 months after the beginning of chemotherapy), to evaluate biplane and 3D EF and global longitudinal strain. Cardiotoxicity and subclinical dysfunction were defined according to American Society of Echocardiography/European Association of Cardiovascular Imaging criteria. Statistical significance was set at p < 0.05. Results The mean age of the patients was 50.1 ± 11.48 years. The frequency of subclinical cardiotoxicity (defined by global longitudinal strain) was 14.9% after 30 days of chemotherapy, 16.7% after 3 months, and 19.7% after 6 months, compared to 4.5%, 3%, and 6.6%, respectively, when clinical cardiotoxicity was determined according to EF. The group that developed subclinical cardiotoxicity by 30 days (group A) had a higher frequency of clinical cardiotoxicity at 3 months (p=0.028) and a lower mean biplane EF after 30 days (p= 0.036) than the group that showed no evidence of subclinical cardiotoxicity (group B). Conclusion Subclinical cardiotoxicity was frequent and began early, being associated with a drop in EF during the clinical course.

RESUMO O objetivo deste trabalho foi avaliar o efeito da inclusão de polpa cítrica na silagem de milho sobre a composição química e parâmetros de fermentação. O delineamento experimental utilizado foi o inteiramente casualizado, com quatro repetições. Os tratamentos foram: Silagem de milho sem polpa cítrica (0%); silagem de milho com 10% 39 de polpa cítrica; silagem de milho com 20% de polpa cítrica; silagem de milho com 30% de polpa cítrica; silagem de milho com 40% de polpa cítrica e silagem de milho com 50% de polpa cítrica. O pH diminuiu linearmente com à inclusão de polpa cítrica, gerando valores distantes do considerado adequado (3,8 a 4,2). Por outro lado, é possível inferior que nem todos os parâmetros fermentativos foram comprometidos, uma vez que, com a inclusão de 33% de polpa cítrica, é possível estimar 30,82 g/kg total N. Com a utilização 45 de 49% de polpa cítrica, é possível obter 95,16 g/kg de proteína bruta. De 21% a 22% de polpa cítrica, foi obtido 549,89 g/kg de fibra em detergente neutro e 678,11 g/kg de nutrientes digestíveis totais. A inclusão de até 30% de polpa cítrica melhorará significativamente a composição química da silagem de milho, devido à redução nos valores de carboidrato estrutural e aumentos nos nutrientes digestíveis totais e proteína.

ABSTRACT The objective of this study was to evaluate the effects of including citrus pulp in maize silage on chemical composition and fermentation parameters. The experimental design was fully randomized with four replicates. Maize silage consisting of 0–50% citrus pulp was produced and analyzed. The pH linearly decreased with the increased inclusion of citrus pulp (3.49 at 50% citrus pulp), which is far below what is considered adequate (3.8–4.2). However, not all fermentation parameters were compromised. At 33% citrus pulp, we estimated 30.82 g/kg total nitrogen. At 49% citrus pulp, we estimated 95.16 g/kg of crude protein. At 21% and 22% citrus pulp, we estimated 549.89 g/kg of neutral detergent fiber and 678.11 g/kg of total digestible nutrients, respectively. Therefore, we conclude that the inclusion of up to 30% citrus pulp improves the complete chemical composition of maize silage owing to the reduction in structural carbohydrate values and increases in total digestible nutrient and protein content.

Abstract Evidence on factors associated with the progression of chronic kidney disease (CKD) is still under construction. The present study aimed to evaluate sociodemographic, clinical, and drug use factors associated with the progression of CKD. A retrospective cohort study was conducted with 193 patients with CKD stages 3A to 5- non-dialysis followed for three years in a Brazilian city. The outcome was the evolution to renal replacement therapy (RRT) or death. A total of 52.3 % (n = 101) were men and 83.4 % (n = 161) elderly. The median age was 72.0 years, and 22.3 % (n = 44) progressed to RRT or death, and the three-year mortality rate was 20.2 %. Participants exposed to angiotensin converting enzyme inhibitors or angiotensin II receptor blockers had a lower risk of progressing to the outcome (hazard ratio (HR) 0.25; p = 0.003) and higher survival (p = 0.022) when compared to those not exposed to these drugs. Age (HR 1.06;) and use of omeprazole (HR 6.25; CI; p <0.01) and hydrochlorothiazide (HR 2.80; p = 0.028) increased the risks of RRT or death. The results highlight the importance of rational management of pharmacotherapy for patients with CKD.

Resumo A atividade microbiana se mostra bastante sensível a mudanças da cobertura, tornando-se um importante indicador de qualidade do solo. O estudo teve como objetivo avaliar as alterações nas atividades microbiológicas do solo sob as diferentes coberturas vegetais no cerrado do Tocantins. O trabalho foi desenvolvido em áreas de Eucalyptus sp., pastagem, agricultura e cerrado sensu stricto na fazenda experimental da Universidade Federal do Tocantins. As amostras de solo foram coletadas em trincheiras de 70 x 70 cm nas profundidades 0-10 e 10-20 cm, com seis repetições. As variáveis avaliadas foram: concentração e estoque de carbono na biomassa microbiana, respiração basal do solo, quociente metabólico e quociente microbiano. A análise estatística foi realizada por meio do teste de normalidade, análise de variância e comparação das médias pelo teste Tukey a 5% de significância. A área com Eucalyptus sp. com 11 anos apresentou uma atividade microbiológica do solo estável, apresentando estoques de carbono na biomassa microbiana superiores em 57,32 % aos da vegetação de mata nativa, 84,29 % ao da pastagem e 290,91 % ao da agricultura. As atividades microbiológicas do solo são afetadas pela variação da cobertura vegetal do solo, sendo eficiente como indicador de qualidade do solo.

Abstract The microbial activity is very sensitive to changes in soil cover, making it an important indicator of soil quality. The study aimed to assess changes in soil microbiological activities under different vegetation coverings in the Cerrado biome of Tocantins state. The work was developed in areas of Eucalyptus sp., Pasture, agriculture and Cerrado sensu stricto in the experimental farm of the Federal University of Tocantins. The soil samples were collected in trenches of 70 x 70 cm at depths 0-10 and 10-20 cm, with six replications. The variables evaluated were: concentration and stock in the microbial biomass carbon, basal soil respiration, metabolic quotient and microbial quotient. The statistical analysis was performed using the normality test, analysis of variance and comparison of means by the Tukey test at 5% significance. The area with Eucalyptus sp. at 11 years of age, he had a stable soil microbiological activity, showing stocks in microbial biomass carbon 57.32% higher than that native forest vegetation, 84.29% that pasture and 290.91% that agriculture. The soil microbiological activities are affected by the variation of the soil vegetation cover, being efficient as an indicator of soil quality.

Resumo A instabilidade patelar é uma condição clínica multifatorial, que acomete um número expressivo de pacientes, ocorrendo devido a variações anatómicas, morfológicas da articulação e do alinhamento patelofemoral. O presente estudo de revisão e atualização da literatura teve como objetivos identificar e sumarizar os conceitos atuais sobre instabilidade patelar em relação aos fatores de risco associados, os critérios diagnósticos e os benefícios e riscos dos tratamentos conservador e cirúrgico. Para tanto, foi realizado um levantamento nas bases de dados eletrónicas MEDLINE (via Pubmed), LILACS e Cochrane Library. Conclui-se que o diagnóstico preciso depende da avaliação clínica detalhada, incluindo o histórico e possíveis fatores de risco individuais, além de exames de imagem. O tratamento inicial da instabilidade patelar é ainda controverso, e requer a combinação de intervenções conservadoras e cirúrgicas, levando em consideração tanto os tecidos moles quanto as estruturas ósseas, sendo estas últimas a razão mais comum para a escolha do tratamento cirúrgico, principalmente instabilidade patelar lateral.

Abstract Patellar instability is a multifactorial clinical condition that affects a significant number of patients and occurs due to morphological variations of the joint and patellofemoral alignment. The present literature review study aimed to identify and summarize current concepts on patellar instability, in relation to associated risk factors, diagnostic criteria, and the benefits and risks of conservative and surgical treatments. For this purpose, a search was conducted in the following electronic databases: MEDLINE (via Pubmed), LILACS and Cochrane Library. It is concluded that the accurate diagnosis depends on the detailed clinical evaluation, including the history and possible individual risk factors, as well as imaging exams. The initial treatment of patellar instability is still controversial, and requires the combination of conservative and surgical interventions, taking into consideration both soft tissues and bone structures, the latter being the most common reason for choosing surgical treatment, especially lateral patellar instability.
