Abstract: COVID-19 rapidly spread across the world in an unprecedented outbreak with a massive number of infected and fatalities. The pandemic was heavily discussed and searched on the internet, which generated big amounts of data related to it. This led to the possibility of attempting to forecast coronavirus indicators using the internet data. For this study, Google Trends statistics for 124 selected search terms related to pandemic were used in an attempt to find which keywords had the best Spearman correlations with a lag, as well as a forecasting model. It was found that keywords related to coronavirus testing among some others, such as “I have contracted covid”, had high correlations (≥0.7) with few weeks of lag (≤4 weeks). Besides that, the ARIMAX model using those keywords had promising results in predicting the increase or decrease of epidemiological indicators, although it was not able to predict their exact values. Thus, we found that Google Trends data may be useful for predicting outbreaks of coronavirus a few weeks before they happen, and may be used as an auxiliary tool in monitoring and forecasting the disease in Brazil.

Resumo Objetivo Este estudo apresenta a tradução e adaptação do Inventário de Taiwan para Transtorno de Personalidade Borderline (IPB) de 20 itens, para o português brasileiro (IPB-P). Métodos Após tradução e retrotradução, a versão em português brasileiro foi aplicada em três amostras: pacientes com transtorno de personalidade borderline, pacientes psiquiátricos com comorbidade de transtorno de uso de substâncias e voluntários sem transtornos mentais relatados. Resultados Diferenças significantes entre os grupos em relação aos graus para borderline (análise de variância [ANOVA], F = 52,923, p = 0,01) foram encontradas mas não houve correlações significantes entre as pontuações para transtorno de personalidade borderline e dependência de álcool ou nicotina. O IPB-P teve uma validade satisfatória para transtorno de personalidade borderline mesmo quando ansiedade e depressão estavam presentes, com uma área sob a ROC (receiver operating characteristic curve) de 0,931 no ponto de corte de 14. Conclusão Este estudo dá suporte para a utilidade potencial do IPB-P como um instrumento de rastreamento para a prática clínica em países de língua portuguesa, incluindo pacientes ambulatoriais com transtorno de uso de álcool e nicotina em remissão precoce ou sustentada.

Abstract Objective The current study presents the translation and adaptation of the 20-item Taiwan version of the Borderline Personality Inventory (BPI) into Brazilian Portuguese (BPI-P). Methods After translation and back-translation, the Brazilian Portuguese version was administered to three samples: patients with borderline personality disorder, psychiatric patients with comorbid substance use disorder and volunteers with no reported mental disorders. Results Significant differences between groups for borderline scores (analysis of variance [ANOVA], F = 52.923, p = 0.01) were found but there were no significant correlations between scores for borderline personality disorder and alcohol or nicotine dependence. The BPI-P had satisfactory validity for borderline personality disorder, even when anxiety and depression were present, with an area under the receiver operating characteristic curve of 0.931 at a cutoff point of 14. Conclusion This study provides support for the potential utility of the BPI-P as a screening instrument for clinical practice in Portuguese speaking countries, including outpatients with alcohol and nicotine use disorders in early or sustained remission.

RESUMO Quantidades de N proveniente de adubos verdes não absorvidas no primeiro ciclo de cultivo, podem ser absorvidas em cultivos subsequentes. Portanto, é importante quantificar e monitorar o efeito residual da adubação verde visando aumentar o seu benefício agronômico nos sistemas de cultivos. O objetivo do trabalho foi estudar o efeito residual das doses do adubo verde Crotalaria juncea aplicadas no cultivo de brócolis, sobre a sucessão abobrinha italiana-milho. O estudo foi realizado em um sistema de sucessão de culturas organizado em três cultivos, com sete tratamentos, sendo os principais quatro doses de adubo verde: 0, 3, 6 e 9 t ha-1. Os tratamentos testemunhas consistiram de adubação mineral, um tratamento com 25 t ha-1 de composto e um outro como testemunha absoluta, sem composto ou adubação mineral. A parcela experimental constou de cinco linhas espaçadas de 0,8 m com 3 m de comprimento. O delineamento experimental foi de blocos casualizados com quatro repetições no esquema de parcelas subdivididas no tempo para as variáveis de crescimento com ajuste dos modelos estatísticos pela metodologia de superfície de resposta. A produção das plantas de abobrinha na maior dose de adubo verde foi superior à produção das plantas na testemunha com 25 t ha-1 de composto e similar com adubação mineral. A produtividade de milho na dose de 9 t ha-1 de adubo verde foi superior somente à produção da testemunha absoluta. Houve efeito residual da massa Crotalaria juncea, aplicada na cultura do brócolis, sobre o crescimento e a produção de abobrinha e produtividade do milho cultivados em sucessão. O efeito residual é dependente da quantidade de massa de Crotalaria juncea aplicada, com os maiores efeitos nas maiores doses.

ABSTRACT Amounts of N from green manures not absorbed in the first cycle can be absorbed by the subsequent crops. Therefore, it is important to quantify and monitor the residual effects of green manure to increase the agronomic benefits of its use in cropping systems. Our purpose was to study the residual effect of doses of the Crotalaria juncea green manure applied in broccoli crop in the zucchini-maize succession. This study was carried out in a crop succession system organized in three crops, with seven treatments and four major doses of green manure as 0, 3, 6, and 9 t ha-1. The control treatments consisted of a mineral fertilization, a treatment with 25 t ha-1 compost, and another as absolute control without organic compost or mineral fertilizer. The experimental plot consisted of five rows spaced 0.8 m with 3 m in length. The experimental design was a completely randomized block with four replications in a split-plot scheme in time for growth with variables of adjustment of statistical models by the response surface methodology. With the highest dose of green manure, the yield of zucchini plants was greater than the yield with 25 t ha-1 compost control and similar with mineral fertilizer. As for the maize yield in the dose of 9 t ha-1 green manure, the yield was superior only to absolute control. There was a residual effect of C. juncea mass, which was applied in broccoli crop for growth and yield of zucchini and maize grown in succession. The residual effect is dependent on the amount of weight of C. juncea applied, with the greatest effects in larger doses.

RESUMO. O experimento foi conduzido, objetivando-se avaliar estratégias de manejo em pastos de capim-mombaça (Panicum maximum) sob lotação intermitente, submetidos a diferentes alturas de resíduo. O delineamento utilizado foi em blocos casualizados, com dois tratamentos (duas diferentes alturas de resíduo pós-pastejo - 30 e 50 cm) e três repetições. Foram avaliadas a altura do pasto no pré e no pós-pastejo, a massa e o acúmulo de forragem, os períodos de descanso, de ocupação, a produção dos componentes morfológicos do pasto, a produção de leite e a qualidade da forragem. Os dados foram submetidos à análise de variância e as médias foram comparadas pelo teste F a 5% de probabilidade. Para tratamentos com intensidade de pastejo mais severa, notou-se maior intervalo de pastejo. Encontrou-se maior acúmulo de forragem para pastos manejados com altura de 50 cm de resíduo de pastejo. Para massa de forragem no pós-pastejo, obteve-se maior produção e maior porcentagem de folhas para o resíduo de 50 cm, bem como maiores teores de PB e digestibilidade para folhas e colmos, e menores teores de lignina e FDN. Para manejo de pastos de capim-mombaça, recomenda-se a altura de 50 cm de resíduo, por promover maior produção de leite por animal e maior número de ciclos de pastejo, garantindo melhor aproveitamento da área.

ABSTRACT. This study was conducted to evaluate management strategies in Mombaça grass pastures (Panicum maximum) under intermittent grazing subjected to different residual heights. A randomized-block design with two treatments (two post-grazing residual heights: 30 and 50 cm) and three replications was adopted. Pasture heights pre- and post-grazing, forage mass and accumulation, rest and occupation periods, pasture morphological components, milk yield and quality forage were evaluated. The data were submitted to analysis of variance and the means were compared by the F test at 5% probability. A longer grazing interval was observed in the treatments under the more severe grazing intensity. For forage mass post-grazing, larger production and higher percentage of leaves were found with the 50 cm residue, as well as higher crude protein contents and digestibility of leaves and stems and lower lignin and neutral detergent fiber contents. The residual height of 50 cm is recommended for the management of Mombaça grass pasture, as it provides greater milk yield per animal and a larger number of grazing cycles, ensuring better use of the area.

RESUMO Fatores intrínsecos (espécie, raça, sexo e idade) e extrínsecos ao animal (nutrição, ambiente e manejos pré e pós-abate) interferem na qualidade da carne ovina. Contudo, não se sabe como variações da coloração das fibras de lã dentro de uma mesma raça podem influenciar as características instrumentais e sensoriais da carne. Assim, objetivou-se com este trabalho investigar o efeito do grupo genético dos animais sobre as características instrumentais e sensoriais da carne de cordeiros Corriedale naturalmente coloridos e brancos. Foram utilizados 29 animais (13 naturalmente coloridos e 16 brancos), criados na região do Bioma Pampa, no Rio Grande do Sul, em condições extensivas de pastagem natural melhorada e abatidos com idade média de 18 meses. As avaliações da carne foram realizadas no músculo longissimus dorsi. Foi utilizada a análise de variância para avaliar o efeito do grupo genético e as médias foram comparadas pelo teste F. Na análise instrumental a carne de cordeiros naturalmente coloridos apresentou coloração mais escura e valores de pH 24 horas, escore de cobertura de gordura e textura mais elevados. A caracterização sensorial foi obtida em quatro sessões utilizando nove julgadores treinados. Nesta avaliação, animais naturalmente coloridos apresentaram coloração da carne mais escura, sabor à gordura e sabor característico à espécie mais elevadas. Apesar de diferenças significativas em alguns aspectos sensoriais, as amostras foram igualmente aceitas pelos julgadores. Cordeiros Corriedale naturalmente coloridos apresentam características instrumentais e sensoriais da carne distintas de cordeiros brancos.

ABSTRACT Sheep meat quality is influenced by a number of factors either intrinsic (species, breed, sex, and age) or extrinsic (nutrition, environment, and pre- and post-slaughter handling) to the animal. However, it is not known whether wool fibre color variations within the same breed can influence the instrumental and sensory characteristics of the meat. Thus, the objective of this study was to investigate the effect of the genetic group on the instrumental and sensory characteristics of meat of white and natural colored Corriedale lambs. The 29 lambs (13 natural colored and 16 white) used in the experiments were raised on natural pasture under extensive grazing conditions in the region of the Pampa Biome, Rio Grande do Sul, Brazil. The animals were slaughtered at average age of 18 months. Meat evaluations were performed on samples from longissimus dorsi muscles. The analysis of variance was used to evaluate the effect of the genetic group and the means were compared by the F test. The instrumental analysis showed that meat of natural colored lambs had darker red color, higher 24 h pH, and higher scores for fat cover and texture. Sensory profiling was performed by nine trained panelists in four sessions. The sensory evaluation showed that natural colored lambs had darker red color, higher scores of fat taste and characteristic taste to the species. Despite significant differences in some sensory aspects, the samples were equally accepted by the panelists. Meat of natural colored Corriedale lambs had different instrumental and sensory profiles from that of white lambs.

Objetivo Mostrar la relación de prótesis dentales con la incidencia y el tipo de lesiones orales desarrollados en la región Seridó, estado de Rio Grande do Norte, Brasil. Método Se realizó un registro de 77 pacientes. Todos eran mayores de 21 años de edad, de ambos sexos, no alcohólicos y/o fumadores crónicos, residentes de los condados correspondientes a la región Seridó, que tenía algún tipo de lesión oral y que fueron admitidos a clínicas dentales de la Universidad de Río Grande del Norte. Allí se observó la relación de estas lesiones con el uso de las prótesis dentales. Resultados En la mayoría de los casos de lesiones orales, estaban relacionadas prótesis que tenían más de 5 años de uso y requerían ser cambiadas. La candidiasis, con el 45,5 % de los casos, y la hiperplasia fibrosa inflamatoria, con el 27,2 %, fueron las lesiones más relacionadas. Conclusiones Se concluye que las prótesis completas y las prótesis parciales removibles mostraron una relación con lesiones orales. Sin embargo, las prótesis completas tuvieron un mayor porcentaje para ser cambiadas y con más de 5 años de uso. Esto demuestra que el tipo parcial removible, incluso sin necesidad de cambio, mostraron una alta correlación con las lesiones.

Objective To show the relationship between dental prostheses and the incidence and type of oral lesions developed in the Seridó region of Brazil. Methods 77 patients were registered. All were over 21 years of age, of both sexes, non-alcoholic and / or chronic smokers, and residents of the municipalities of the region corresponding to Seridó. They also all had some type of oral lesion and had been admitted to dental clinics of the University of Rio Grande do Norte. Here, the relationship between these lesions and the dental prostheses that they used was observed. Results The majority of dental prostheses related to oral lesions had more than 5 years of use and required changing. Candidiasis (45.5 %) and inflammatory fibrous hyperplasia (27.2 %) were the lesions most related to the dental prostheses. Conclusions Complete prostheses and removable partial dentures correlated with oral lesions. However, the complete prostheses had a higher percentage ready for change-out and had more than 05 years of use. This demonstrates that removable partial dentures, even without the need for exchange, showed a high correlation with the oral lesions.

Objetivo Mostrar a relação da prótese dentária com a incidência e o tipo de lesões bucais desenvolvidos na região do Seridó, estado do Rio Grande do Norte, Brasil. Método Foi realizado um cadastro de 77 pacientes, todos com mais de 21 anos de idade, ambos os gêneros, não etilistas e/ou tabagistas crônicos, residentes nos municípios correspondentes a região do Seridó, que apresentavam algum tipo de lesão bucal e que deram entrada nas Clínicas Odontológicas da Universidade do Rio Grande do Norte, sendo observado a relação destas com o uso de próteses dentárias. Resultados A maioria das próteses relacionadas com lesões orais possuía mais de 05 anos de uso e indicação de troca, e que a Candidose, com 45,5 % dos casos e Hiperplasia fibrosa inflamatória, com 27,2 % foram às lesões mais relacionadas. Conclusões As próteses dentárias totais e parciais removíveis apresentaram relação com lesões orais, no entanto, a prótese total apresentou maior percentual de peças indicadas para troca e com mais de 05 anos de uso; mostrando que o tipo parcial removível a grampo mesmo sem indicações de troca, apresentaram uma alta relação com lesões.

Com o objetivo de investigar a potencialidade de registro no MAPA para indicação aos produtores do Norte e Noroeste Fluminense, três populações de milho pipoca oriundas do programa de seleção recorrente da Universidade Estadual do Norte Fluminense Darcy Ribeiro (ciclos C3, C4 e C5 de UNB2U), cinco híbridos simples cedidos pelo programa de melhoramento da Universidade Estadual de Maringá, bem como cinco variedades (BRS Angela, UFVM-2 Barão de Viçosa, Viçosa, Beija-Flor e SAM) e três híbridos comerciais (Zelia, Jade e IAC 112) foram avaliados em cinco ambientes. O delineamento experimental adotado foi blocos ao acaso, com três repetições, tendo sido avaliadas as duas principais características da cultura de importância econômica: produtividade de grãos (GY) e capacidade de expansão (PE). Na análise de variância conjunta, observaram-se diferenças significativas pelo teste F para as características GY e PE. Em relação à interação genótipos x ambientes, apenas GY foi significativa, evidenciando comportamento diferenciado das cultivares nos ambientes. Pela estatística Pi e os resultados para estas características demonstram que a população UNB2U-C5 e o híbrido P1 x P7 têm potencial para recomendação como nova opção de cultivo para os produtores da região.

Three populations of popcorn from the Universidade Estadual do Norte Fluminense Darcy Ribeiro recurrent selection program (cycles C3, C4 and C5 from UNB2U), five simple hybrids provided by the Universidade Estadual de Maringá breeding program, five varieties (BRS Angela, UFVM-2 Barão de Viçosa, Viçosa, Beija-Flor and SAM) and three commercial hybrids (Zelia, Jade and IAC 112) were evaluated in five environments for their potential to be registered by the MAPA and recommended to producers in Northern and Northwestern Rio de Janeiro State. The experiment was arranged in a randomized block design, with three replications. The two main economic traits of the crops, grain yield (GY) and popping expansion (PE), were assessed. In the joint analysis of variance, significant differences were observed using the F test for the GY and PE traits. Regarding the genotype x environment interaction, only the GY was significant, thus revealing that the cultivar behavior varies according to the environment. The Pi statistics and the results for those traits showed that UNB2U-C5 and hybrid P1 x P7 have the potential to be recommended as new alternatives for producers in the region.

OBJECTIVE: Despite the high prevalence of substance abuse and mood disorders among victimized children and adolescents, few studies have investigated the association of these disorders with treatment adherence, represented by numbers of visits per month and treatment duration. We aimed to investigate the effects of substance abuse and mood disorders on treatment adherence and duration in a special program for victimized children in São Paulo, Brazil. METHODS: A total of 351 participants were evaluated for psychiatric disorders and classified into one of five groups: mood disorders alone; substance abuse disorders alone; mood and substance abuse disorders; other psychiatric disorders; no psychiatric disorders. The associations between diagnostic classification and adherence to treatment and the duration of program participation were tested with logistic regression and survival analysis, respectively. RESULTS: Children with mood disorders alone had the highest rate of adherence (79.5%); those with substance abuse disorders alone had the lowest (40%); and those with both disorders had an intermediate rate of adherence (50%). Those with other psychiatric disorders and no psychiatric disorders also had high rates of adherence (75.6% and 72.9%, respectively). Living with family significantly increased adherence for children with substance abuse disorders but decreased adherence for those with no psychiatric disorders. The diagnostic correlates of duration of participation were similar to those for adherence. CONCLUSIONS: Mood and substance abuse disorders were strong predictive factors for treatment adherence and duration, albeit in opposite directions. Living with family seems to have a positive effect on treatment adherence for patients with substance abuse disorders. More effective treatment is needed for victimized substance-abusing youth

This study investigated the seropositivity for hepatitis B virus (HBV), the vaccination index, and the vaccine response index in dentists from Campo Grande, MS. Blood samples from 474 dentists (63.7% women and 36.3% men), with a mean age of 38.5 ± 10.5 years were analyzed by enzyme-linked immunosorbent assay to detect the serological markers: HBsAg, anti-HBs, and anti-HBc. The HBsAg positive samples were tested for anti-HBc IgM, HBeAg, and anti-HBe. A total of 51 (10.8%) dentists showed seropositivity for HBV. Three (0.6%) were HBsAg/anti-HBc/anti-HBe positive, 43 (9.1%) were anti-HBc/anti-HBs positive, and 5 (1.1%) had only anti-HBc. Viral DNA was detected by polymerase chain reaction in 9 (17.6%) out of 51 HBV seropositive samples. A vaccination index of 96.6% (458/474) was observed, although 73.1% (335/458)completed the three-dose schedule. Excluding 46 HBV seropositive individuals from 458 that reported vaccination, 412 were analyzed for vaccine response index. It was observed that 74.5% (307/412) were anti-HBs positive; this percentage increased to 79.1% when three doses were administered. The results showed a high vaccination index and a good rate of vaccine response; however, the failure in completing the three-dose schedule and the occurrence of HBV infection reinforce the need for more effective prevention strategies.
