ABSTRACT: The use of nitrogen (N) in pastoral ecosystems leads to increased productivity, as it allows the plant to elongate its leaves and, therefore, grazing herbivores harvest the green leaves. However, there are very volatile N sources, which can be replaced by ammonium nitrate, which is less volatile and less dependent on the application in rainy days. The treatments are compound of Marandu palisade grass pastures managed under continuous stocking at a canopy height of 25 cm, with different levels of N fertilizer: 0, 75, and 150 kg ha-1year-1, as ammonium nitrate (32% of N), with four replicates (pastures) in a completely randomized design. Nitrogen uptake (54.9, 96.5, 113.8 kg N ha-1) and N nutrition index (0.67, 0.98, 1.15) were different between N level, respectively, 0, 75 and 150 kg ha-1 year-1. The N recovery (58.3, 40.9 %) differed between 75 and 150 kg ha-1 year-1, respectively. The dose of 75 kg N kg ha-1 year-1 results in better N utilization, while the dose of 150 kg N ha-1 year-1 enables greater stocking rate; therefore, requiring less grazing area.

RESUMO: O uso de nitrogênio (N) em ecossistemas pastoris leva ao aumento da produtividade, pois permite que a planta alongue suas folhas e, portanto, os herbívoros colham as folhas verdes. Porém, existem fontes de nitrogênio muito voláteis, que devem ser substituídas por nitrato de amônio, que é menos volátil e menos dependente da aplicação em dias chuvosos. Os tratamentos foram compostos por pastagens de capim-marandu, manejadas sob lotação contínua, na altura do dossel a 25 cm, com diferentes doses de N: 0, 75 e 150 kg ha-1 ano-1, na forma de nitrato de amônio (32% de N), com quatro repetições (piquetes), em delineamento inteiramente casualizado. A absorção de nitrogênio (54,9; 96,5; 113,8 kg N ha-1) e o índice nutricional de N (0,67; 0,98; 1,15) foram diferentes entre as doses de N, respectivamente, 0, 75 e 150 kg ha-1 ano-1. A recuperação de N (58,3; 40,9%) diferiu entre 75 e 150 kg ha-1 ano-1, respectivamente. A dose de 75 kg N kg ha-1 ano-1 resultou em melhor aproveitamento do N, enquanto a dose de 150 kg N ha-1 ano-1 possibilita maior taxa de lotação; portanto, exigindo menos área de pastagem.

Abstract Background Ischemic stroke is an important cause of death in the world. The malignant middle cerebral artery infarction (MMCAI) has mortality as high as 80% when clinically treated. In this setting, decompressive craniectomy is a life-saving measure, in spite of high morbidity among survivors. Objective To evaluate the outcomes of patients with MMCAI treated with decompressive craniectomy in a Brazilian academic tertiary stroke center. Methods A prospective stroke database was retrospectively evaluated, and all patients treated with decompressive craniectomy for MMCAI between January 2014 and December 2017 were included. The demographics and clinical characteristics were evaluated. The functional outcome, measured by the modified Rankin Scale (mRS), was assessed at hospital discharge, after 3-months and 1-year of follow-up. Results We included 53 patients on the final analysis. The mean age was 54.6 ± 11.6 years and 64.2% were males. The median time from symptoms to admission was 4.8 (3–9.7) hours and the mean time from symptoms to surgery was 36 ± 17 hours. The left hemisphere was the affected in 39.6%. The median NIHSS at admission was 20 (16–24). The in-hospital mortality was 30.2%. After a median of 337 [157–393] days, 47.1% of patients had achieved favorable outcome (mRS ≤ 4) and 39.6% had died. Conclusion Decompressive craniectomy is a life-saving measure in the setting of MMCAI, and its effects remains important in the scenario of a middle-income country in real-world situations.

Resumo Antecedentes O acidente vascular cerebral (AVC) isquêmico é uma causa importante da morte em todo o mundo. O infarto maligno da artéria cerebral média (IMACM) tem mortalidade de até 80% quando tratado clinicamente. Nesse contexto, a craniectomia descompressiva é uma medida salvadora de vidas, apesar da alta morbidade entre os sobreviventes. Objetivo Avaliar os desfechos dos pacientes com IMACM tratados com craniectomia descompressiva em um centro acadêmico terciário de AVC no Brasil. Métodos Um banco de dados prospectivo de AVC foi avaliado retrospectivamente e todos os pacientes tratados com craniectomia descompressiva para IMACM entre janeiro de 2014 e dezembro de 2017 foram incluídos. As características clínicas e demográficas foram avaliadas. Os desfechos funcionais, medidos pela escala modificada da Rankin (mRS), foram avaliados na alta hospitalar, após 3 meses e após 1 ano de seguimento. Resultados Foram incluídos 53 pacientes na análise final. A idade média foi 54,6 ± 11,6 anos e 64,2% eram homens. A mediana do tempo dos sintomas à admissão foi 4,8 (3–9,7) horas e o tempo médio dos sintomas à cirurgia foi 36 ± 17 horas. O hemisfério esquerdo foi o afetado em 39,6%. A pontuação na escala de AVC do National Institute of Health (NIHSS) à admissão foi 20 (16–24). A mortalidade hospitalar foi 30,2%. Após uma mediana de 337 (157–393) dias, 47,1% dos pacientes tinham atingido um desfecho favorável (mRS ≤ 4) e 39,6% tinham morrido. Conclusão Craniectomia descompressiva é uma medida salvadora de vidas no contexto do IMACM e seus efeitos permanecem importantes no cenário de um país em desenvolvimento em situação de vida real.

Resumo Foram analisadas tendências da mortalidade prematura por doenças crônicas não transmissíveis (DCNT) entre 1990 e 2019, as projeções até 2030 e os fatores de risco atribuíveis a estas doenças na Comunidade dos Países de Língua Portuguesa (CPLP). Utilizou-se estimativas do estudo Carga Global de Doenças e análise da carga de mortalidade prematura por DCNT para nove países da CPLP, utilizando taxas padronizadas por idade, usando-se RStudio. Portugal, Brasil, Guiné Equatorial, Angola e Guiné Bissau apresentam taxas de mortalidade prematura por DCNT em declínio e; Timor Leste, Cabo Verde, São Tomé e Príncipe e Moçambique apresentaram aumento das taxas. As projeções indicam que nenhum dos países deverá atingir as metas de redução em um terço da mortalidade prematura por DCNT até 2030. A carga de doença atribuível mostrou que os fatores de riscos mais importantes em 2019 foram: pressão arterial sistólica elevada, tabaco, riscos dietéticos, índice de massa corporal elevado e poluição do ar. Conclui-se pelas profundas diferenças na carga de DCNT entre os países, com melhores resultados em Portugal e Brasil e que nenhum país do CPLP deverá atingir a meta de redução das DCNT até 2030.

Abstract The present study analyzed trends in premature mortality from Noncommunicable diseases (NCDs) between 1990 and 2019, the projections up to 2030, and the risk factors (RFs) attributable to these diseases in the Community of Portuguese Language Countries (CPLP). Estimates from the Global Burden of Disease (GBD) study and the analysis of the burden of premature mortality due to NCDs were used for nine CPLP countries, applying age-standardized rates, using RStudio. Portugal, Brazil, Equatorial Guinea, Angola, and Guinea Bissau showed declining premature mortality rates caused by NCDs, while East Timor, Cape Verde, São Tomé and Príncipe, and Mozambique showed an increase in rates. Projections indicate that none of the countries is expected to achieve the goals of reducing premature mortality due to NCDs by one third by 2030. The attributable burden of disease showed that the most important RFs in 2019 were: high systolic blood pressure (SBP), tobacco, dietary risks, high body mass index (BMI), and air pollution. It can therefore be concluded that there are profound differences in the burden of NCDs among the countries, with better results in Portugal and Brazil, and that no CPLP country is likely to reach the NCD reduction target by 2030.

Abstract Objective Research and identification of Cutibacterium acnes (C. acnes) and other microorganisms in deeptissue samples collected in clean shoulder surgeries of patients who did not undergo any previous invasive joint procedure and who had no clinical history of infection. Methods We analyzed the results of cultures of intraoperative deep tissue samples from 84 patients submitted to primary clean shoulder surgery. Tubes containing culture medium were used for storage and transport of anaerobic agents, prolonged incubation time, and mass spectrometer for diagnosis of bacterial agents. Results Bacteria growth was evidenced in 34 patients (40.4%) of the 84 included in the study. Of these, 23 had growth of C. acnes in at least one sample of deep tissue collected, corresponding to 27.3% of the total patients. The second most common agent was Staphylococcus epidermidis, present in 7.2% of the total individuals included. We showed a higher relationship between sample positivity and males, a lower mean age, absence of diabetes mellitus, ASA I score, and antibiotic prophylaxis in anesthetic induction with cefuroxime. Conclusions A high percentage of isolates of different bacteria was found in shoulder tissue samples of patients undergoing clean and primary surgeries, who had no history of previous infection. Identification of C. acnes was high (27.6%), and Staphylococcus epidermidis was the second most frequent agent (7.2%).

Resumo Objetivo Pesquisa e identificação de Cutibacterium acnes (C. acnes) e de outros microrganismos em amostras de tecidos profundos coletados em cirurgias limpas de ombro em pacientes que não foram submetidos a nenhum procedimento invasivo articular prévio e que não possuíam antecedentes clínicos de infecção. Métodos Foram analisados os resultados das culturas de amostras de tecidos profundos intraoperatórias de 84 pacientes submetidos à cirurgia limpa primária do ombro. Foram utilizados tubos contendo meio de cultivo para armazenamento e transporte de agentes anaeróbicos, tempo prolongado de incubação e espectrômetro de massa para diagnósticos de agentes bacterianos. Resultados Foi evidenciado o crescimento de bactérias em 34 pacientes (40,4%) dos 84 incluídos no estudo. Desses, 23 apresentavam crescimento de C. acnes em pelo menos uma amostra de tecido profundo coletada, correspondendo a 27,3% do total de pacientes. O segundo agente mais encontrado foi o Staphylococcus epidermidis, presente em 7,2% do total de indivíduos incluídos. Evidenciamos maior relação da positividade de amostras com o gênero masculino, uma média de idade inferior, a ausência de diabetes mellitus, o escore ASA I e a profilaxia antibiótica na indução anestésica com cefuroxima. Conclusões Verificou-se um elevado percentual de isolados de diferentes bactérias em amostras de tecidos de ombros de pacientes submetidos a cirurgias limpas e primárias e sem histórico de infecção anterior. A identificação de C. acnes foi elevada (27,6%) e o Staphylococcus epidermidis foi o segundo agente mais frequente (7,2%).

Abstract: En | Text: En | PDF: En

Cariniana estrellensis (Raddi) Kuntze seedlings have been used in forest restoration programs in the Atlantic Forest biome. However, despite the economic and ecological relevance of this species, to date no general method for rapid identification of primary and secondary metabolites of C. estrellensis leaves has been reported. In this work, we explore the feasibility of using rapid analysis by nuclear magnetic resonance techniques and liquid chromatography coupled to diode array, charged aerosol, and mass detection. The main secondary metabolites identified were hydrolysable tannins, quinic acid, hydroxycinnamic acids (trans-p-coumaric acid, cis p coumaric acid, and trans-ferulic acid), and flavonoids (kaempferol and quercetin derivatives). These compounds are particularly useful as chemotaxonomic markers for the genus Cariniana and for the family Lecythidaceae, and may also be important for pharmacological uses and for the survival of the seedlings in reforestation programs.

Abstract Gliomas comprise the vast majority of all malignant brain tumors. Low-grade glioma patients with combined whole-arm losses of 1p and 19q chromosomes were shown to have significantly better overall survival rates compared to non-deleted patients. This work evaluates several approaches for assessment of 1p/19q status from T2-weighted magnetic resonance images, using radiomics and machine learning. Experiments were performed using images from a public database (102 codeleted, 57 non-deleted). We experimented with sets of 68 and 100 radiomic features, and with several classifiers, including support vector machine, k-nearest neighbors, stochastic gradient descent, logistic regression, decision tree, Gaussian naive Bayes, and linear discriminant analysis. We also experimented with several ensemble-based methods, including four boosting-based classifiers, random forest, extra-trees, and bagging. The performance of these methods was compared using various metrics. Our best results were achieved using a bagging ensemble estimator based on the decision tree classifier, using only texture-based radiomics features. Compared to other works that used the same database, this approach provided higher sensitivity. It also achieved higher sensitivity than that provided by neurosurgeons and neuroradiologists analyzing the same images. We also show that including radiomic features associated with first order statistics and shape does not improve the performance of the classifiers, and in many cases worsens it. The molecular assessment of brain tumors through biopsies is an invasive procedure, and is subject to sampling errors. Therefore, the techniques presented in this work have strong potential for aiding in better clinical, surgical, and therapeutic decision-making.

ABSTRACT Objective: the aim of this study was to compare the results of open and videolaparoscopic transvesical prostatectomy techniques in the treatment of benign prostatic hyperplasia (BPH) in a tertiary hospital. Methods: we reviewed medical records of patients who underwent transvesical adenectomy due to BPH between March 2019 and March 2021 at the urology service of Hospital de Clínicas do Paraná (HCPR), 42 patients were included in the open transvesical prostatectomy group and 22 in the videolaparoscopic group. Then, a comparison was made between the techniques in terms of surgical time, bleeding, length of stay, need for intensive care, among others, in addition to postoperative outcome. Results: the mean surgical time was shorter in the open technique compared to the laparoscopic technique (141 min vs 274 min). The videolaparoscopic group had a shorter mean hospital stay (3.5 days vs 6.36 days). There was no statistical significance in the comparison regarding the need for an intensive care unit, as well as in the assessment of postoperative bleeding. Conclusion: comparatively, the techniques demonstrated a similar outcome, with a low rate of complications and satisfactory results for the treatment of BPH. The laparoscopic technique is a surgery with a shorter hospital stay, but at the expense of a longer surgical time.

RESUMO Objetivo: o objetivo deste estudo foi comparar o resultado das técnicas de prostatectomia transvesical aberta e videolaparoscópica no tratamento de hiperplasia prostática benigna (HPB) em um hospital terciário. Métodos: foram revisados prontuários de pacientes submetidos a adenectomia transvesical devido a HPB entre março de 2019 a março de 2021 no serviço de urologia do Hospital de Clínicas do Paraná (HCPR), sendo incluídos 42 pacientes no grupo prostatectomia transvesical aberta e 22 no grupo videolaparoscópico. Em seguida foi feita a comparação entre as técnicas nos quesitos tempo cirúrgico, sangramento, tempo de internamento, necessidade de terapia intensiva, entre outras, além de desfecho pós-operatório. Resultados: o tempo cirúrgico médio foi menor na técnica aberta em comparação com a técnica videolaparoscópica (141 min vs 274 min). O grupo videolaparoscópico apresentou um tempo médio de internamento menor (3,5 dias vs 6,36 dias). Não houve significância estatística na comparação quanto a necessidade de unidade de terapia intensiva, assim como na avaliação do sangramento pós-operatório. Conclusão: comparativamente, as técnicas demonstraram um desfecho semelhante, com baixa taxa de complicações e resultados satisfatórios para o tratamento da HPB. Sendo a técnica videolaparoscópica uma cirurgia com menor tempo de internamento, porém às custas de um maior tempo cirúrgico. .

Abstract Background Cardiovascular complications of COVID-19 are important aspects of the disease’s pathogenesis and prognosis. Evidence on the prognostic role of troponin and myocardial injury in Latin American hospitalized COVID-19 patients is still scarce. Objectives To evaluate myocardial injury as independent predictor of in-hospital mortality and invasive mechanical ventilation support in hospitalized patients, from the Brazilian COVID-19 Registry. Methods This cohort study is a substudy of the Brazilian COVID-19 Registry, conducted in 31 Brazilian hospitals of 17 cities, March-September 2020. Primary outcomes included in-hospital mortality and invasive mechanical ventilation support. Models for the primary outcomes were estimated by Poisson regression with robust variance, with statistical significance of p<0.05. Results Of 2,925 patients (median age of 60 years [48-71], 57.1% men), 27.3% presented myocardial injury. The proportion of patients with comorbidities was higher among patients with cardiac injury (median 2 [1-2] vs. 1 [0-2]). Patients with myocardial injury had higher median levels of brain natriuretic peptide, lactate dehydrogenase, creatine phosphokinase, N-terminal pro-brain natriuretic peptide, and C-reactive protein than patients without myocardial injury. As independent predictors, C-reactive protein and platelet counts were related to the risk of death, and neutrophils and platelet counts were related to the risk of invasive mechanical ventilation support. Patients with high troponin levels presented a higher risk of death (RR 2.03, 95% CI 1.60-2.58) and invasive mechanical ventilation support (RR 1.87, 95% CI 1.57-2.23), when compared to those with normal troponin levels. Conclusion Cardiac injury was an independent predictor of in-hospital mortality and the need for invasive mechanical ventilation support in hospitalized COVID-19 patients.

Resumo Fundamento As complicações cardiovasculares da COVID-19 são aspectos importantes da patogênese e do prognóstico da doença. Evidências do papel prognóstico da troponina e da lesão miocárdica em pacientes hospitalizados com COVID-19 na América Latina são ainda escassos. Objetivos Avaliar a lesão miocárdica como preditor independente de mortalidade hospitalar e suporte ventilatório mecânico em pacientes hospitalizados, do registro brasileiro de COVID-19. Métodos Este estudo coorte é um subestudo do registro brasileiro de COVID-19, conduzido em 31 hospitais brasileiros de 17 cidades, de março a setembro de 2020. Os desfechos primários incluíram mortalidade hospitalar e suporte ventilatório mecânico invasivo. Os modelos para os desfechos primários foram estimados por regressão de Poisson com variância robusta, com significância estatística de p<0,05. Resultados Dos 2925 pacientes [idade mediana de 60 anos (48-71), 57,1%], 27,3% apresentaram lesão miocárdica. A proporção de pacientes com comorbidades foi maior nos pacientes com lesão miocárdica [mediana 2 (1-2) vs. 1 (0-20)]. Os pacientes com lesão miocárdica apresentaram maiores valores medianos de peptídeo natriurético cerebral, lactato desidrogenase, creatina fosfoquinase, N-terminal do pró-peptídeo natriurético tipo B e proteína C reativa em comparação a pacientes sem lesão miocárdica. Como fatores independentes, proteína C reativa e contagem de plaquetas foram relacionados com o risco de morte, e neutrófilos e contagem de plaquetas foram relacionados ao risco de suporte ventilatório mecânico invasivo. Os pacientes com níveis elevados de troponina apresentaram um maior risco de morte (RR 2,03, IC95% 1,60-2,58) e suporte ventilatório mecânico (RR 1,87;IC95% 1,57-2,23), em comparação àqueles com níveis de troponina normais. Conclusão Lesão cardíaca foi um preditor independente de mortalidade hospitalar e necessidade de suporte ventilatório mecânico em pacientes hospitalizados com COVID-19.

Abstract Background The Good Practices in Cardiology Program is an initiative created by the Brazilian Society of Cardiology (SBC) to improve the quality of care of cardiovascular disease patients in Brazilian public hospitals. Objectives To characterize patients admitted to a tertiary public hospital with diagnosis of acute coronary syndrome (ACS) or heart failure (HF) and to evaluate performance indicators in both ACS and HF arms, with a pre-established target of 85% adherence to the SBC recommendations. Methods This was a descriptive cross-sectional study through data collection of patients hospitalized between May 2016 and September 2019. Results A total of 1,036 patients were included, 273 in the HF arm and 763 in the ACS arm. Mean age was 59.8 ± 12.0 years in the ACS and 57.0 ± 14.1 years in the HF, with a predominance of male patients in both groups. More than half of patients had some primary education and more than 90% reported a monthly income of less than five minimum wages. In ACS, the diagnosis of ACS with ST segment elevation was predominant (66.3%), and 2.9% of patients died. In HF, the most common etiology was Chagas disease (25.8%), and 17.9% died. Analysis of the performance indicators revealed an adherence rate higher than 85% to nine of the 12 indicators. Conclusion Quality programs are essential for improvement of quality of care. Performance indicators pointed to a good adherence to the SBC guidelines, mainly in the ACS arm.

Resumo Fundamento O Programa Boas Práticas em Cardiologia é uma iniciativa da Sociedade Brasileira de Cardiologia (SBC) destinada à melhoria do cuidado cardiovascular nos hospitais públicos brasileiros. Objetivos Descrever características dos pacientes internados com Síndrome Coronariana Aguda (SCA) e Insuficiência Cardíaca (IC) e avaliar os indicadores de desempenho alcançados nos braços (SCA e IC) em um hospital público terciário, com uma meta pré-estabelecida de 85% de aderência às recomendações da SBC. Métodos Estudo do tipo transversal descritivo realizado por meio da coleta de dados de pacientes que estiveram internados entre maio de 2016 e setembro de 2019. Resultados Foram incluídos 1036 pacientes, 273 pacientes no braço IC e 763 no braço SCA. A média de idade foi de 59,8 ± 12,0 anos na SCA e 57,0 ± 14,1 anos na IC, com predomínio do sexo masculino em ambos os grupos. Mais da metade dos pacientes não tinham ensino fundamental completo e mais de 90% declararam renda mensal inferior a cinco salários-mínimos. Na SCA, predominou o diagnóstico de SCA com supradesnivelamento do segmento ST (66,3%) e 2,9% dos pacientes foram a óbito. Na IC, a etiologia mais comum foi a Doença de Chagas (25,8%) e 17,9% dos pacientes foram a óbito. Na avaliação dos indicadores de desempenho, nove dos 12 indicadores tiveram taxas de aderência acima de 85%. Conclusão Programas de qualidade são essenciais à melhoria do cuidado e os indicadores de desempenho do hospital apontam para uma boa adesão às diretrizes assistenciais da SBC, particularmente no braço da SCA.

Abstract Hydrocotyle umbellata L., Araliaceae, is a species that is recommended in Ayurvedic medicine for its effects on the central nervous system, such as anxiolytic and memory-stimulant effects. Despite the medicinal potential of this species, its phytopharmaceutical and technological potential to produce standardized extracts has not been investigated. This study analyzes the influence of spray drying parameters on the contents of the chemical markers (total phenolic, total flavonoid, and hibalactone) and the functional properties of H. umbellata extract. The optimization of drying conditions was performed using a central composite design combined with response surface methodology and desirability function approach. The mathematical models fitted to experimental data indicated that all the evaluated drying parameters significantly influenced the chemical contents. The optimal conditions were: inlet temperature of 120 °C, feed flow rate of 4 mL min-1, and colloidal silicon dioxide:maltodextrin ratio of 16%:4%. Under these conditions, the powder samples had spherical particles and desirable physicochemical and functional properties, such as low water activity and moisture content, good product recovery, reconstitution, and flowability. Thus, spray drying might be a promising technique for processing standardized H. umbellata extracts.

ABSTRACT. This study aimed to evaluate cassava genotypes to identify the ones with the best nutritional values for ruminant diets. Nine genotypes were used: Amansa Burro (BGM 549), Aramaris (BGM 116), Brasília, Cambadinha (BRS Guaíra), Curvelinha, Engana Ladrão (BGM 1269), Trouxinha (BGM 1468), BRS Gema de Ovo, and BRS Dourada. A completely randomized block experimental design with nine treatments (genotypes) and three blocks (replicates) were employed. The roots were analyzed for dry matter production (DMP) in tonnes per hectare, crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF), starch, and in vitro dry matter digestibility (IVDMD). The multivariate analysis was carried out using Ward’s hierarchical agglomerative clustering based on Mahalanobis distance. The groups formed were evaluated by Scott-Knott test. The group formed by genotype Engana Ladrão was chosen as the best one for having the highest DMP t ha-1 and IVDMD values and the lowest NDF and ADF contents.

Abstract: En | Text: En | PDF: En

ABSTRACT Objective: The purpose of these guidelines is to provide specific recommendations for the surgical treatment of neck metastases in patients with papillary, follicular, and medullary thyroid carcinomas. Materials and methods: Recommendations were developed based on research of scientific articles (preferentially meta-analyses) and guidelines issued by international medical specialty societies. The American College of Physicians’ Guideline Grading System was used to determine the levels of evidence and grades of recommendations. The following questions were answered: A) Is elective neck dissection indicated in the treatment of papillary, follicular, and medullary thyroid carcinoma? B) When should central, lateral, and modified radical neck dissection be performed? C) Could molecular tests guide the extent of the neck dissection? Results/conclusion: Recommendation 1: Elective central neck dissection is not indicated in patients with cN0 well-differentiated thyroid carcinoma or in those with noninvasive T1 and T2 tumors but may be considered in T3-T4 tumors or in the presence of metastases in the lateral neck compartments. Recommendation 2: Elective central neck dissection is recommended in medullary thyroid carcinoma. Recommendation 3: Selective neck dissection of levels II–V should be indicated to treat neck metastases in papillary thyroid cancer, an approach that decreases the risk of recurrence and mortality. Recommendation 4: Compartmental neck dissection is indicated in the treatment of lymph node recurrence after elective or therapeutic neck dissection; “berry node picking” is not recommended. Recommendation 5: There are currently no recommendations regarding the use of molecular tests in guiding the extent of neck dissection in thyroid cancer.
