Abstract Background: Alarms alert healthcare professionals of deviations from normal/physiologic status. However, alarm fatigue may occur when their high pitch and diversity overwhelm clinicians, possibly leading to alarms being disabled, paused, and/or ignored. We aimed to determine whether a staff educational program on customizing alarm settings of bedside monitors may decrease inconsistent alarms in the Post-Anesthesia Care Unit (PACU). Methods: This is a prospective, analytic, quantitative, pragmatic, open-label, single-arm study. The outcome was evaluated on PACU admission before (P1) and after (P2) the implementation of the educational program. The heart rate, blood pressure, and oxygen saturation alarms were selected for clinical consistency. Results: A total of 260 patients were included and 344 clinical alarms collected, with 270 (78.4%) before (P1), and 74 (21.6%) after (P2) the intervention. Among the 270 alarms in P1, 45.2% were inconsistent (i.e., false alarms), compared to 9.4% of the 74 in P2. Patients with consistent alarms occurred in 30% in the P1 and 27% in the P2 (p = 0.08). Patients with inconsistent alarms occurred in 25.4% in the P1 and in 3.8% in the P2. Ignored consistent alarms were reduced from 21.5% to 2.6% (p = 0.004) in the P2 group. The educational program was a protective factor for the inconsistent clinical alarm (OR = 0.11 [95% CI 0.04-0.3]; p < 0.001) after adjustments for age, gender, and ASA physical status. Conclusion: Customizing alarm settings on PACU admission proved to be a protective factor against inconsistent alarm notifications of multiparametric monitors.

Resumen Este estudio tuvo como objetivo evaluar el efecto de la inoculación con L. buchneri liofilizado y/o activado sobre las poblaciones de bacterias de ácido láctico en ensilajes de maíz. Los tratamientos experimentales consistieron en ensilaje de maíz sin aditivo y ensilaje con los inoculantes L. buchneri 1 × 10 5 ufc/g, aplicados según las recomendaciones del fabricante (1 g/tonelada de forraje) en las formas de inoculante liofilizado e inoculante preactivado. Se identificaron aislados purificados de ensilajes de maíz con y sin inocu lación, y el 93% de los aislados correspondieron a bacterias de ácido láctico de la especie L. plantarum. Entre los aislados no se detectaron bacterias de la especie L. buchneri. La aplicación de L. buchneri liofilizado o activado en la masa ensilada promueve un aumento considerable de la población de bacterias de ácido lácticas en los ensilajes de maíz durante todo el período de fermentación.

Abstract This study aimed to evaluate the effect of inoculation with lyophilised and/or activated Lactobacillus buchneri on lactic acid bacteria populations in corn silage. Experimental treatments consisted of corn silage without additives or silage with the inoculants of L. buchneri (1 x 10 5 cfu/g) applied according to the manufacturer’s recommendations (1 g/tonne fodder) in the forms of the lyophilised inoculant and pre-activated inoculant. Purified isolates from corn silage with and without the inoculant were identified, and 93% of the isolates corresponded to the lactic acid bacteria of the species Lactobacillus plantarum. Among the isolates, no bacteria of the species L. buchneri were detected. The application of lyophilised or activated L. buchneri improved the microbiological profile and reduced ethanol production in corn silage, even without being identified among the isolates captured 70 days after ensilage.

Abstract This study aimed to evaluate the quality of Tanzania grass (Panicum maximum) haylage with varying contents of dry matter (DM) and stored for 90 days. The quality of this grass was evaluated through the lens of a variety of physiochemical properties (e.g., chemical composition, aerobic stability, pH, microbial profile, etc.). A completely randomized design was used with four treatments (in natura, 400, 500, and 600 g kg-1 DM) and five replicates. Treatment with 600 g kg-1 DM yielded the highest DM haylage (p < 0.01) and soluble carbohydrate content (p < 0.01). Treatment in natura resulted in the highest O2 concentration inside the bales (p < 0.01), whereas treatments with 500 and 600 g kg-1 DM resulted in the highest CO2 values. The highest acetic acid concentrations of 36.4 ± 1.6, 38.2±1.6, and 48.9 ± 1.6 g kg-1 DM (p < 0.01) were observed post the in natura, 500 g kg-1 DM, and 600 g kg-1 DM treatments, respectively. Treatment with 600 g kg-1 DM yielded the highest pH value at hour zero (p < 0.01). Tanzania grass with 500 and 600 g kg-1 DM produced the highest quality haylage.

ABSTRACT Purpose to verify the relationship between the risk of falling, the level of confidence in activities involving balance, and age with the values of gain and symmetry of the semicircular canals (SSCs), using the Head Video Impulse Test (vHIT) in patients with peripheral vestibular dysfunction. Methods Cross-sectional study in 12 individuals submitted to functional evaluation using the Activities-specific Balance Confidence Scale (ABC Scale) and the Dynamic Gait Index (DGI), and vestibular evaluation with vHIT. The results were compared using Spearman's Correlation Coefficient. Results There was a predominance of females (75%), with a mean age of 59 years and 8 months. The mean score in DGI was 19.70 points and on the ABC Scale, 43.65%, which is characteristic of a low confidence level. A moderate correlation was observed between age and DGI and between DGI and ABC Scale and SCC gain and symmetry values with vHIT. Conclusion A relationship was observed between a higher risk of falling in patients with vestibular hypofunction and advanced age and between a low level of confidence to perform daily activities due to asymmetrical SCC gain. balance SSCs, SSCs , (SSCs) vHIT (vHIT dysfunction Crosssectional Cross sectional 1 Activitiesspecific Activities specific DGI, (DGI) Spearmans Spearman s Coefficient 75%, 75 75% (75%) 5 months 1970 19 70 19.7 4365 43 65 43.65% (SSCs (DGI 7 (75% 197 19. 436 4 6 43.65 (75 43.6 (7 43.

Abstract: The objective of this study was to evaluate the quality of milk and cheese and sensory analysis of cheese from goats that received a diet with different levels of sorghum silage in the diet. Twenty Anglonubian dairy goats were used, with an average age of 2 years, average live weight of 43.7 kg, distributed in a completely randomized design, with five replications. Moisture (P=0.001), total solids (P=0.001), fat (p=0.001), TDE (P=0.006) and protein (P=0.003) of goat cheese showed a significant difference due to the inclusion of silage from goat cheese. sorghum in the diet. The sensory attributes soft appearance (P<.0001), look (P<.0001), salty taste (P<.0001) and smooth texture (P=0.0430) showed a significant difference depending on the level of sorghum silage added to the diet. of goats. In the PC analysis, it is observed that three main components were needed to represent the variation of 64.84% of the data. PC 1 determined 29% of the data variation and was represented by the attributes with the highest averages: attractive aroma (5.87) and global acceptability (7.74). The inclusion of up to 45% of sorghum silage in the diet of goats increased milk and cheese fat, which favored high scores for the attributes of softness and global acceptance.

Abstract This work aims to evaluate, at different stages, the productive performance, carcass quality, and intestinal biometry of European quails (Coturnix coturnix Coturnix), consuming diets with increasing levels of seaweed bran (Sargassum sp). A total of 240 European quail chicks (Coturnix coturnix Coturnix) were distributed in a completely randomized design, with four levels of bran inclusion (0.0, 2.5, 5.0, and 7.5%), 6 replications with 10 birds in each experimental plot. In the period from 1 to 21 days, the feed intake of the control group was higher, with lower water consumption. In the period from 22 to 42 days, feed and water consumption increased with the inclusion of seaweed, but with a reduction in weight gain. In the total period, water consumption was higher at the level of 2.5 and 7.5%, with lower consumption in the control group, with a small reduction in slaughter and carcass weight with the inclusion of bran. There was no difference (P > 0.05) in carcass quality and intestinal biometry. We recommended the inclusion of up to 7.5% of sargassum meal in the diet of European quails at all stages, without compromising its productive performance, carcass quality, and intestinal biometry. evaluate stages performance Coturnix Coturnix, , Sargassum sp. sp . sp) 24 design 0.0, 00 0 (0.0 25 2 5 50 5.0 75 7 7.5%) plot days 4 gain 2.

RESUMO Esta pesquisa teve como objetivo caracterizar o efeito da reabilitação vestibular (RV) sobre o ganho do reflexo vestíbulo-ocular (RVO), a ocorrência das sacadas compensatórias, bem como sobre o equilíbrio corporal e a qualidade de vida, em três pacientes com hipofunção vestibular periférica. Trata-se de um estudo descritivo. Participaram da pesquisa três pacientes do gênero feminino, duas com 55 anos e uma com 67 anos, com diagnóstico médico de disfunção vestibular periférica. As participantes foram submetidas à anamnese, questionário Dizziness Handicap Inventory (DHI), avaliação clínica do equilíbrio corporal e ao Vídeo Teste do Impulso Cefálico (vHIT), pré e após RV. A RV foi aplicada de forma personalizada, baseada no protocolo de Cawthorne e Cooksey, associada a estímulos de realidade virtual. Após a RV, observou-se a redução da média do escore total do DHI, sugestivo da diminuição na restrição de participação. Na avaliação clínica do equilíbrio obtiveram-se resultados dentro da normalidade para as provas alteradas, pré RV. Quanto ao vHIT, constatou-se aumento do ganho do RVO para os canais semicirculares anteriormente afetados, condizente com padrões de normalidade, e extinção ou diminuição de ocorrência das sacadas compensatórias, nos três casos avaliados. O aumento do ganho do RVO e a extinção ou redução das sacadas compensatórias, após a RV, evidenciam sinais sugestivos de compensação vestibular. Esses resultados mostraram-se compatíveis com o aumento da estabilidade postural e menor restrição da qualidade de vida. Os achados, em conjunto, demonstram o benefício proporcionado pela RV nos três casos avaliados.

ABSTRACT The purpose of this research is to characterize the vestibular rehabilitation (VR), vestibulo-ocular reflex (VOR) gain, the occurrence of compensatory saccades, the static and dynamic balance, and the impact on quality of life in three patients with peripheral vestibular hypofunction. This is a descriptive study, approved by the ethics in research committee, under number 4,462.519. Three female patients participated in the study, two aged 55 and one aged 67, with a medical diagnosis of peripheral vestibular dysfunction. The participants underwent anamnesis, Dizziness Handicap Inventory (DHI) questionnaire, clinical assessment of postural balance and Video Head Impulse Test (vHIT), pre and post VR. The VR was applied in a personalized manner, based on the Cawthorne and Cooksey protocol, associated with virtual reality stimuli. After VR, a reduction in the total score average of DHI was observed, suggesting a decrease in participation restriction. The clinical balance assessment results were within the normal range for the altered tests, pre VR. In the three evaluated cases, vHIT showed increased RVO gain for the previously affected semicircular ducts (SCDs), compatible with normality standards, and reduction or extinction in the occurrence of compensatory saccades. The increase in VOR gain and the reduction or suppression of compensatory saccades after VR are suggestive signs of vestibular compensation. These results were compatible with increased postural stability and less restricted quality of life. These findings demonstrate the benefit provided by VR in the three evaluated cases.

Abstract Brazil, the world’s largest citros producer, yields around 19 million tons per year and exports most part of its production as orange juice. Essential oils (EOs) extracted from leaves, fruit and flowers of many species of the genus Citrus have been widely used as the result of their promising bioactivities. The fungus Rhizopus stolonifer (Ehrenb.) Vuill., an agent which causes soft rot in fruit, has been considered one of the main factors that cause postharvest diseases, thus, leading to major economic losses in agribusiness. This research aimed at evaluating the chemical composition and in vitro antifungal effect of EOs from two varieties of fresh Citrus sinensis (lima orange and bahia navel orange) peel on mycelial growth of R. stolonifer. EOs were obtained by hydrodistillation, which was carried out by a Clevenger-type apparatus, while their chemical composition was analyzed by gas chromatography-flame ionization detection (GC-FID) and gas chromatography-mass spectrometry (GC-MS). Limonene was the major monoterpene identified in EOs from lima orange (95.2%) and bahia navel orange (93.2%) peel. EOs from lima orange and bahia navel orange inhibited 91.95% and 80.05% mycelial growth of R. stolonifer, respectively, at the highest dose under evaluation (100 µL). This study revealed the biotechnological potential of EOs extracted from fruit peel of two varieties of citros which may applied to biofilm preparation, so as to coat and preserve different types of fruit.

RESUMO A introdução da zircônia (ZrO2) como material odontológico representa um grande avanço quando comparado aos demais materiais tradicionalmente utilizados para esta finalidade. Este material destaca-se, devido às suas ótimas propriedades tais como resistência mecânica e biocompatibilidade. No entanto, existem limitações quanto a sua coloração branca e alta opacidade, não sendo possível mimetizar as características da dentição humana, afetando assim o conceito estético desses materiais e diminuindo o conforto do paciente. Este trabalho propõe desenvolver pós de zircônia pigmentada através do método Pechini, dopando-os com óxido de ferro em diferentes concentrações (3 %, 2 %, 1 %, 0,5 %, 0,25 % em mol) e itria, posteriormente calciná-los a temperatura de 1000 °C, com a finalidade de obter a mistura química mais efetiva, próxima da tonalidade da dentina humana. As amostras foram caracterizadas por Difração de Raios X (DRX), Microscopia Eletrônica de Varredura (MEV), Espectroscopia de Energia Dispersiva (EDS), teste de toxicidade e avaliação colorimétrica, confirmando a presença do ferro dentro da microestrutura da zircônia e suas modificações causadas no material. Os resultados indicam que os tamanhos de cristalitos dos pós sintetizados aumentaram de 35,45 nm para 48,97 nm, quando a concentração de ferro aumentou de 0 % para 3%. Os espectros de EDS indicaram a presença de ferro em todas as amostras, com variadas concentrações do pigmento. O método utilizado foi efetivo para a produção de pós de zircônia com variadas nuances de cores, possuindo um grande potencial para aplicações odontológicas.

ABSTRACT The introduction of zirconia (ZrO2) as a dental material, represents a major advance when compared to other materials traditionally used for this purpose. This material stands out due to its excellent properties such as mechanical resistance and biocompatibility. However, there are limitations regarding its white color and high opacity, and it is not possible to mimic the characteristics of human dentition, thus affecting the aesthetic concept of these materials and reducing patient comfort. This work proposes to develop pigmented zirconia powders using the Pechini method, doping them with iron oxide in different concentrations (3 %, 2 %, 1 %, 0.5 %, 0.25 mol%) and itria, later calcine them at a temperature of 1000 °C in order to obtain the most effective chemical mixture, close to the shade of human dentin. The samples were characterized by X-ray Diffraction (XRD), Scanning Electron Microscopy (SEM), Energy Dispersive Spectroscopy (EDS), toxicity testing and colorimetric evaluation, confirming the presence of iron within the zirconia microstructure and its modifications caused in the material. The obtained results indicate that the crystallite sizes of the synthesized powders increased from 35,45 nm to 48,97 nm when the iron concentration increased from 0 % to 3 mol%. The EDS spectra indicated the presence of iron in all the samples, with varying concentrations of the pigmentant agent. The method used was effective for the production of zirconia powders with varied color nuances, having great potential for dental applications.

RESUMO O cistadenoma mucinoso apendicular é entidade rara que causa mucocele apendicular, sendo mais frequente em mulheres acima dos 50 anos. Em metade dos casos, o cistadenoma mucinoso apendicular é assintomático. A tomografia do abdome é o padrão-ouro para um diagnóstico pré-operatório. O tratamento é cirúrgico e tem bom prognóstico; a ressecção completa evolui sem ruptura apendicular e sem extravasamento. Relatamos um caso de paciente homem de 64 anos com cistadenoma mucinoso apendicular. Foi realizada hemicolectomia laparoscópica direita. Esse é um procedimento que pode ser usado com segurança no tratamento de mucocele apendicular, desde que seja executado com cautela.

ABSTRACT Appendiceal mucinous cystadenoma is a rare entity, which causes appendicular mucocele. It is more frequent in women over 50 years old. In half of the cases it is asymptomatic. Tomography of the abdomen is the gold standard in its preoperative diagnosis. The treatment is surgical, with good prognosis, the complete resection evolves without appendicular rupture and extravasation. We report a case of a 64-year-old man with appendiceal mucinous cystadenoma. A laparoscopic right hemicolectomy was performed. This therapy that can be safely used to treat appendiceal mucocele, as long as it is cautious.

Layered or fibrous clay minerals are used as adsorbents because they have good performance to remove inorganic and organic species. In this work, a Brazilian fibrous clay mineral was applied to remove Remazol Yellow GR industrial dye from simple and binary systems; this was performed in the presence of lead in the latter case. The adsorption efficiency was investigated under various conditions of pH, time, temperature and dye concentration. The experimental data were fitted to the kinetic pseudo-first- and pseudo-second-order models, and the isotherms were fitted to the Langmuir and Freundlich models. The maximum adsorption capacity was 20.08 mg g-1 at pH 2, 240 minutes and 298 K, and these data were better fit by the kinetic pseudo-second-order model. The equilibrium study was fitted to the Langmuir model at 298 K and Freundlich for other temperatures and binary systems. The dye sorption in the presence of lead was decreased to 15 mg g-1. Therefore, palygorskite behaved as a promising solid for treating effluents.

Cytomegalovirus infection is a frequent complication after transplantation. This infection occurs due to transmission from the transplanted organ, due to reactivation of latent infection, or after a primary infection in seronegative patients and can be defined as follows: latent infection, active infection, viral syndrome or invasive disease. This condition occurs mainly between 30 and 90 days after transplantation. In hematopoietic stem cell transplantation in particular, infection usually occurs within the first 30 days after transplantation and in the presence of graft-versus-host disease. The major risk factors are when the recipient is cytomegalovirus seronegative and the donor is seropositive as well as when lymphocyte-depleting antibodies are used. There are two methods for the diagnosis of cytomegalovirus infection: the pp65 antigenemia assay and polymerase chain reaction. Serology has no value for the diagnosis of active disease, whereas histology of the affected tissue and bronchoalveolar lavage analysis are useful in the diagnosis of invasive disease. Cytomegalovirus disease can be prevented by prophylaxis (the administration of antiviral drugs to all or to a subgroup of patients who are at higher risk of viral replication) or by preemptive therapy (the early diagnosis of viral replication before development of the disease and prescription of antiviral treatment to prevent the appearance of clinical disease). The drug used is intravenous or oral ganciclovir; oral valganciclovir; or, less frequently, valacyclovir. Prophylaxis should continue for 90 to 180 days. Treatment is always indicated in cytomegalovirus disease, and the gold-standard drug is intravenous ganciclovir. Treatment should be given for 2 to 3 weeks and should be continued for an additional 7 days after the first negative result for viremia.

A ressonância magnética (RM) possui diversas vantagens na avaliação de pacientes oncológicos portadores de lesões torácicas, sejam elas lesões de parede, pleurais, pulmonares, mediastinais, esofagianas, cardíacas ou linfonodais. É uma ferramenta bastante útil no manejo destes pacientes, seja no diagnóstico, no estadiamento, no planejamento cirúrgico, na avaliação de resposta ou no seguimento. No presente artigo os autores contextualizam a importância da RM na avaliação das lesões torácicas de pacientes oncológicos. Por se tratar de um equipamento disponibilizado universalmente, sem os riscos da irradiação ionizante, com elevada resolução de contraste e espacial, aliada a novas técnicas como a cine-RM, a perfusão e a difusão, a RM pode atuar como uma ferramenta alternativa, economicamente viável, e com performance comparável ou complementar aos métodos radiológicos convencionais como a radiografia simples, a tomografia computadorizada e a PET/CT na avaliação dos pacientes portadores de neoplasias torácicas.

Magnetic resonance imaging (MRI) has several advantages in the evaluation of cancer patients with thoracic lesions, including involvement of the chest wall, pleura, lungs, mediastinum, esophagus and heart. It is a quite useful tool in the diagnosis, staging, surgical planning, treatment response evaluation and follow-up of these patients. In the present review, the authors contextualize the relevance of MRI in the evaluation of thoracic lesions in cancer patients. Considering that MRI is a widely available method with high contrast and spatial resolution and without the risks associated with the use of ionizing radiation, its use combined with new techniques such as cine-MRI and functional methods such as perfusion- and diffusion-weighted imaging may be useful as an alternative tool with performance comparable or complementary to conventional radiological methods such as radiography, computed tomography and PET/CT imaging in the evaluation of patients with thoracic neoplasias.

O objetivo deste trabalho foi avaliar as correlações do índice de área do cladódio com características morfogênicas e produtivas da palma forrageira (Nopalea sp. e Opuntia sp.). Foram avaliados três clones de palma forrageira, em condições de sequeiro: IPA Sertânia, Miúda e Orelha de Elefante Mexicana. Dados morfológicos dos cladódios e da planta, índice de área do cladódio e biomassa acumulada foram obtidos na ocasião da colheita. A relação entre os dados coletados foi avaliada por meio da análise de trilha, após a aplicação da matriz de correlação de Pearson e do teste de multicolinearidade. Foram observadas maiores correlações das características morfogênicas com o rendimento da cultura do que com o índice de área do cladódio, com R2 entre 0,5930 e 0,9502. As variáveis altura x largura e número total de cladódios foram as que melhor explicaram a variação do índice de área do cladódio. O número total de cladódios, o índice de área do cladódio e a morfologia dos cladódios de quarta ordem são as variáveis que melhor explicam a variabilidade do rendimento dos clones de palma forrageira avaliados em ambiente semiárido.

The objective of this work was to evaluate the correlations of the cladode area index with morphogenetic and yield traits of the cactus forage (Nopalea sp. and Opuntia sp.). Three clones of cactus forage were evaluated in dry land conditions: IPA Sertânia, Miúda, and Orelha de Elefante Mexicana. Morphological data from cladode and plant, cladode area index, and accumulated dry biomass were obtained at harvest. The relationship between the collected data was analyzed by path analysis, after the application of Pearson's correlation matrix and the multicollinearity test. Higher correlations of morphogenetic traits were observed with crop yield than with the cladode area index, with R2 between 0.5930 and 0.9502. The variables height x width and total number of cladodes were the ones that best explained the variation of the cladode area index. The total number of cladodes, the cladode area index, and the morphology of fourth-order cladodes are the variables that best explain the yield variability of the cactus forage clones evaluated in semiarid environment.
