ABSTRACT: Surface contamination by pathogenic and deteriorating microorganisms is a constant concern in the food industry. Therefore, in this study we evaluated the antimicrobial activity of silver nanoparticles (AgNPs), produced using the essential oil of Lippia origanoides Kunth and ethanolic extract of Hymenaea martiana Hayne, against bacteria used in milk processing. For this, AgNPs were synthesized and their antimicrobial activity was evaluated for minimum inhibitory and bactericidal concentrations, time-kill, interference on the biofilm, and application on the surfaces of different materials. AgNPs showed bacteriostatic and bactericidal activity against Staphylococcus aureus (ATCC 25923), Staphylococcus aureus (ATCC 33591), Escherichia coli (ATCC 25922), Salmonella enterica subsp. enterica serovar Choleraesuis (ATCC 10708), Listeria monocytogenes, Escherichia coli, Salmonella spp.,andPseudomonas aeruginosa,and interfered with biofilm formation more than with consolidated biofilms. A 1hour period was sufficient to reduce the bacterial cells, whereas a Minimum Duration for Killing (MDK) of 99% was reached after approximately 30 min. AgNPs were effective against bacteria attached to stainless steel and polyethylene, but ineffective on tile surfaces. Thus, owing to the growing microbial resistance and the need to develop new products based on the concepts of green chemistry, these AgNPs are presented as a new possibility for cleaning processes in the food industry.

RESUMO: A contaminação de superfícies por micro-organismos patogênicos e deteriorantes é uma preocupação constante na indústria de alimentos. Dessa forma, o objetivo deste trabalho foi avaliar a atividade antimicrobiana de nanopartículas de prata (AgNPs) produzidas utilizando óleo essencial de Lippia origanoides Kunth e extrato etanólico da Hymenaea martiana Hayne, frente a bactérias de importância na contaminação em áreas de processamento do leite. Para isso, as AgNPs foram sintetizadas e sua atividade antimicrobiana foi avaliada através das concentrações inibitória e bactericida mínimas, tempo de morte, interferência sobre o biofilme, e por fim, a sua aplicação sobre superfícies de diferentes materiais. As AgNPs apresentaram atividade bacteriostática e/ou bactericida frente à Staphylococcus aureus (ATCC 25923), Staphylococcus aureus (ATCC 33591), Escherichia coli (ATCC 25922), Salmonella enterica subsp. enterica serovar Choleraesuis (ATCC 10708), Listeria monocytogenes, Escherichia coli, Salmonella spp. e Pseudomonas aeruginosa, e interferiram na formação do biofilme mais do que sobre o biofilme consolidado. O tempo de uma hora foi o suficiente para reduzir as populações bacterianas, enquanto o Minimum Duration for Killing MDK 99% foi atingido próximo a 30 minutos. As AgNPs foram eficientes contra bactérias aderidas ao inox e ao polietileno. Assim, tendo em vista a crescente resistência microbiana e o desenvolvimento de novos produtos baseados nos conceitos da química verde, essas nanopartículas de prata apresentam-se como uma nova possibilidade de uso nos processos de higienização da indústria de alimentos.

Abstract Osteoporosis can affect a significant part of the population and fractures are the most common complications associated with this disease, leading to high public health costs. Thus, the prevention of fractures is relevant to individuals with signs and symptoms as well as to the health system. Postmenopausal osteoporosis has been associated with oxidative stress, emphasizing the importance of an efficient defense system to maintain bone health. Lycopene is a carotenoid with antioxidant properties that may stimulate osteoblastogenesis and inhibit osteoclastogenesis. The purpose of this investigation was to analyze the influence of lycopene in the bone neoformation of calvaria defects in ovariectomized rats utilizing the concentration of 45 mg/kg. Wistar Hannover female rats were divided into ovariectomized and sham groups. The ovariectomized animals received 45 mg/kg lycopene (OvxL) or water (Ovx) by daily gavage the day after ovariectomy/sham surgery for 16 weeks. Twelve weeks after ovariectomy, there were performed 5-mm calvaria defects followed by euthanasia after 4 weeks. Samples of bone tissue were collected to perform morphological and morphometrical analysis of the neoformed bone area, and percentage with Software Image J. Morphological evaluation showed mature bone with more osteocytes in the group OVxL when compared to the other groups. The morphometrical analysis demonstrated a significant increase of bone neoformation in the group OvxL (p<0.05). The data obtained suggest that lycopene benefits bone repair in the absence of estrogenic hormones.

Resumo A osteoporose afeta grande parte da população e as fraturas são as complicações mais importantes relacionadas a essa doença, gerando altos gastos para o poder público. Dessa forma, a prevenção de fraturas decorrentes da osteoporose torna-se relevante tendo em vista que gera benefícios tanto para o indivíduo acometido pela doença quanto para o sistema de saúde. A osteoporose pós menoupasa tem sido associada ao estresse oxidativo, portanto, um eficiente sistema de defesa antioxidante é primordial para a manutenção da saúde óssea. O licopeno é um carotenoide antioxidante que aparentemente estimula a osteoblastogênese e inibe a osteoclastogênese. O objetivo deste estudo foi analisar a influência do licopeno na neoformação óssea em defeitos de calvária em ratas ovariectomizadas utilizando a concentração de 45 mg/kg. Foram utilizados 15 ratas Wistar Hannover pesando aproximadamente 200g, sendo que 10 animais foram submetidos à ovariectomia bilateral e 5 (Grupo Sham) foram submetidos à simulação da cirurgia de ovariectomia bilateral. Os animais ovariectomizados foram divididos aleatoriamente em 2 grupos: Ovariectomizado (Ovx) e Ovariectomizado Licopeno (OvxL) que receberam água e licopeno respectivamente, por sonda gástrica, diariamente. As administrações iniciaram-se no dia seguinte à cirurgia de ovariectomia e/ou da exposição dos ovários e foram mantidas por 120 dias, data de realização da eutanásia. O grupo Sham recebeu água diariamente. Noventa dias após a ovariectomia bilateral foram confecionados defeitos ósseos nas calvárias de todos os animais e após trinta dias as ratas foram eutanasiadas. As amostras de tecido ósseo foram coletadas e foi realizado o processamento para a obtenção das lâminas histológicas. Foram realizadas as análises morfológicas e morfométrica, onde foi estimada a área (mm2) e porcentagem (%) relativa de osso neoformado utilizando o Software Image J. A avaliação morfológica evidenciou a ação benéfica do licopeno pois os animais que receberam esse antioxidante apresentaram um tecido ósseo mais maduro, com maior presença de osteócitos quando comparados aos demais grupos. Por meio das análises morfométricas verificou-se maior neoformação óssea para os animais que receberam o licopeno (p<0,05). Diante dos resultados obtidos, concluiu-se que o licopeno na concentração de 45 mg/Kg teve efeito benéfico no processo de reparação, promovendo significante formação óssea frente à ausência de hormônios estrogênicos.

Resumo Objetivo Analisar o perfil das regulações das unidades pré-hospitalares fixas de um município paulista. Metodologia: Estudo observacional descritivo retrospectivo, cuja amostra compreendeu os dados dos indivíduos regulados das unidades durante o ano de 2019. Ao final da coleta dos dados, foi realizada uma análise estatística descritiva. Resultados Foram encontrados dados válidos de 9.984 referenciamentos. A média de tempo de liberação da vaga foi de 26,6 horas (± 35,8). Dentre todos os pacientes regulados, 1.592 (15,9%) não concluíram seus destinos, tendo como desfechos: alta (9,3%), óbito (2,3%), evasão (2,8%) ou encerramento de ficha (1,5%). O tempo médio de permanência na unidade dos pacientes que receberam alta foi de 40,8 horas (±36,2), enquanto para os que vieram a óbito foi de 40,9 horas (±42,7). Conclusões Os tempos de espera para liberação das vagas de internação solicitadas pelas unidades pré-hospitalares estão mais elevados do que os recomendados pela literatura. Tal fato pode provocar piores desfechos aos pacientes regulados e extrapola as competências do serviço de emergência definidas pelo Ministério da Saúde.

Abstract Objective To analyze the profile of referrals from the emergency department in a city in the state of São Paulo, Brazil. Methodology: This is a retrospective descriptive observational study. The sample of this study included the data of individuals referred by the emergency department during the year of 2019. At the end of data collection, a descriptive statistical analysis was performed. Results Valid data from 9,984 referrals were found. The average time to the release of the hospital bed was 26.6 hours (± 35.8). Among all referred patients, 1,592 (15.9%) did not complete their destinations, evolving to one of the following outcomes: medical discharge (9.3%), death (2.3%), patient dropout (2.8%) or termination of its file (1.5%). The average length of stay in the unit for patients who were discharged was 40.8 hours (±36.2), while for those who died it was 40.9 hours (±42.7). Conclusions The waiting times for releasing the hospital beds requested by the emergency department are longer than those recommended in the literature. This can cause worse outcomes for referred patients and goes beyond the competencies of the emergency service as defined by the Brazilian Ministry of Health.

Abstract We critically analyzed clinical trials performed with chloroquine (CQ) and hydroxychloroquine (HCQ) with or without macrolides during the first wave of COVID-19 and discussed the design and limitations of peer-reviewed studies from January to July 2020. Seventeen studies were eligible for the discussion. CQ and HCQ did not demonstrate clinical advantages that justified their inclusion in therapeutic regimens of free prescription for treatment or prophylactic purposes, as suggested by health authorities, including in Brazil, during the first wave. Around August 2020, robust data had already indicated that pharmacological effects of CQ, HCQ and macrolides as anti-SARS-CoV-2 molecules were limited to in vitro conditions and largely based on retrospective trials with low quality and weak internal validity, which made evidence superficial for decision-making. Up to that point, most randomized and nonrandomized clinical trials did not reveal beneficial effects of CQ or HCQ with or without macrolides to reduce lethality, rate of intubation, days of hospitalization, respiratory support/mechanical ventilation requirements, duration, type and number of symptoms, and death and were unsuccessful in increasing virus elimination and/or days alive in hospitalized or ambulatory patients with COVID-19. In addition, many studies have demonstrated that side effects are more common in CQ-or HCQ-treated patients.

Abstract The aim of this study was to evaluate the time elapsed from first symptoms to the treatment of oral and oropharyngeal cancer (OOC) and to identify variables associated with treatment delay. This is an observational study with retrospective and prospective data collection. Patients with a diagnosis of OOC seen at the Head and Neck Surgery outpatient clinic of a Brazilian public hospital were included and followed up to treatment initiation. Participants answered a questionnaire for the collection of socioeconomic, demographic, cultural, and clinical information, as well as information about the time elapsed from first symptoms to the first appointment with a head and neck surgeon. Time to treatment was classified into four intervals: 1- first symptoms to first medical appointment; 2- first medical appointment to specialized medical care; 3- specialized medical care to preparation for treatment; and 4- preparation for treatment to treatment initiation. Bivariate statistics were computed. Out of 100 participants, nine died before treatment. Mean time to treatment was 217 days. Highest mean time was observed for interval 2 (94 days), followed by interval 1 (63 days), interval 4 (39 days), and interval 3 (21 days). At interval 1, a longer time was associated with severe alcohol consumption, severe smoking, and family history of cancer. At interval 2, the delay was associated with appointment with a general practitioner, clinical diagnosis of disease other than cancer, and antibiotic prescription. At interval 4, delay in treatment was associated with surgical treatment. Patients with OOC experience delays from symptom onset to treatment initiation. The longest interval was associated with professional delay, followed by patient delay in help-seeking.

Abstract The região extremo sul da Bahia (RESB - Extreme Southern Region of Bahia) has agricultural aptitude for several crops and has already been subjected to the expansion of sugarcane and coffee. Thus, this work analyzes the spatial and temporal dynamics of sugarcane and coffee monocultures in the RESB and their relationship with socioeconomic indices. The methodology consists of collection and analysis of data from the Instituto Brasileiro de Geografia e Estatística (IBGE), which is the main provider of geographic information and statistics in Brazil, the Companhia Nacional de Abastecimento (CONAB), which is responsible for providing technical information to support decision-making regarding the elaboration of policies aimed at agriculture and the Atlas Brasil platform. Data were collected regarding the planted area and the amount of sugarcane and coffee produced in the region between 1988 and 2019. To understand the relationship between expansion and socioeconomic factors, data related to gross domestic product (GDP) and municipal human development index (MHDI) were collected. This study identified the main sugarcane-producing municipalities (Caravelas, Mucuri, Medeiros Neto, Nova Viçosa, Lajedão, Ibirapuã and Santa Cruz Cabrália) and coffee (Prado, Itamaraju, Porto Seguro, Eunapolis, Teixeira de Freitas and Itabela). The expansion of these crops presents economic importance for the region, but presents a little contribution to the improvement of the various factors that make up the MHDI of the municipalities. This study concluded that the expansion of these crops changed the agricultural matrix of the region due to its specialization in the production of these crops to the detriment of others such as cocoa, for example.

Resumo A Região Extremo Sul da Bahia (RESB) possui aptidão agrícola para diversas culturas e já foi sujeita à expansão da cana-de-açúcar e do café. Assim, esse trabalho analisa a dinâmica espacial e temporal das monoculturas da cana-de-açúcar e do café na RESB e sua relação com índices socioeconômicos. A metodologia consiste em coleta e análise dos dados junto ao Instituto Brasileiro de Geografia e Estatística (IBGE), que é o principal provedor de informações geográficas e estatísticas do Brasil, a Companhia Nacional de Abastecimento (CONAB), que é responsável por fornecer informações técnicas para apoiar a tomada de decisão sobre a elaboração de políticas voltadas para a agricultura, e a Plataforma Atlas Brasil. Foram coletados dados sobre a área plantada e a quantidade produzida de cana-de-açúcar e de café na região entre os anos 1988 e 2019. Para compreender a relação entre a expansão e os fatores socioeconômicos, foram levantados dados referentes ao Produto Interno Bruto (PIB) e Índice de Desenvolvimento Humano Municipal (IDHM). Este trabalho identificou os principais municípios produtores de cana-de-açúcar (Caravelas, Mucuri, Medeiros Neto, Nova Viçosa, Lajedão, Ibirapuã e Santa Cruz Cabrália) e de café (Prado, Itamaraju, Porto Seguro, Eunápolis, Teixeira de Freitas e Itabela), e a expansão desses cultivos apresenta importância econômica para a região, porém apresenta pouca contribuição para a melhoria dos diversos fatores que compõem o IDHM dos municípios. Esse estudo concluiu que a expansão desses cultivos alterou a matriz agrícola da região devido a sua especialização na produção desses cultivos em detrimento de outros como o cacau, por exemplo.

Abstract In Compost-Bedded Pack Barn (CBP) systems, air velocity is linked with the thermal comfort of housed dairy cattle and bedding quality and, therefore, assessing ventilation efficiency is essential. In this context, the objective of this study was to evaluate and characterize dependence and spatial distribution of air velocity at the 1.5 m height (vair,M) and at bedding level (vair,B) in an open CBP system with positive pressure ventilation. The study was conducted in 2021, in a facility located in the Zona da Mata region, Minas Gerais, Brazil. The facility area was divided into a mesh composed of 55 equidistant points, where vair,M and vair,B data were collected in the morning (09:00 a.m.) and afternoon (03:00 p.m.) periods, during three weeks in Brazilian winter. Geostatistics techniques were used to assess dependence and spatial distribution. In both periods evaluated, there were a strong occurrence of spatial dependence and non-uniform vair,M and vair,B distributions. The vair,M and vair,B values were lower than recommended (1.8 m∙s–1) in more than 65.0% of the area. Adequate ventilation levels were observed only in the first 20.0 m of the facility, from Southeast to Northwest, because of the fan lines present.

ABSTRACT Objective to analyze the spatial-temporal distribution and factors associated with HIV/AIDS mortality among young people in the Northeast from 2001 to 2020. Method ecological study with 2,509 deaths from HIV/AIDS from northeastern residents aged between 10 and 24 years of age, reported in the Mortality Information System. Temporal analysis techniques (Joinpoint) and detection of spatial clusters (Spatial Autocorrelation, Gets-Ord Gi* and Scan were used. Three spatial error and spatial lag (Spatial Error and Spatial Lag) and non-spatial regression models (Ordinary Least Squares-OLS) were used to identify the factors associated with mortality in northeastern municipalities, considering p<0.05. Results the HIV/AIDS mortality rate among young people in the northeast was 0.4 deaths per 100,000 inhabitants. Maranhão (APC:7.1; CI95%:2.3-12.1), Sergipe (PcA:6.9; CI95%:1.8-12.2), Rio Grande do Norte (PcA:6.4; CI95%:1.8-11.2), Ceará (PcA:4.2; CI95%:1.5-7.0) and Alagoas (APC:3.2; CI95%:0.1-6.4) showed a significant increasing trend of deaths. Cluster detection techniques indicated clusters of deaths mainly on the coast of Pernambuco and north-central Maranhão. The indicators proportion of the population in households with density >2 (β=0.012; p<0.001) and per capita transfer of the continued benefit (β=0.000; p<0.001) showed a positive relationship with the outcome. On the other hand, the proportion of extremely poor people (β=-0.011; p=0.029) and the Brazilian Deprivation Index (β=-0.195; p=0.009) were negatively associated with mortality. Conclusion there was a trend of increased mortality in five of the nine northeastern states. The spatial clusters were located mainly in Pernambuco and North-Central Maranhão. Interventions aimed at socioeconomic factors should be established to prevent HIV infections and deaths among young people.

Intervenções direcionadas aos fatores socioeconômicos devem ser firmadas para prevenir as infecções e mortes por HIV entre jovens.

ABSTRACT Sweet sorghum has been shown to be an alternative for ethanol production in several regions. Because it is sexually propagated, the use of quality seeds becomes an important factor for obtaining an adequate plant stand and, consequently, good productivity. Thus, the objective was to evaluate the production and physiological maturation of seeds of sweet sorghum cv. BRS 511, in response to the interval between irrigations during the reproductive period and harvesting period. Two experiments were carried out in a greenhouse, the experimental design adopted was in randomized blocks, with four replications in a 3 x 2 split-plot scheme, corresponding to three intervals between irrigations during the reproductive stage (0; 4 and 8 days) and two harvest times (102 and 110 days after sowing). The following parameters were evaluated from the harvested panicles: number of seeds, weight of one thousand seeds, water content, germination, first germination count, emergence in sand and emergence speed, electrical conductivity and seedling vigor. The production of seeds per panicle and the weight of a thousand seeds were significantly influenced by the increase in the interval between irrigations in the 2nd experiment, with a reduction of 50.4 and 46.3%, respectively. Water replacement every eight days caused a reduction of up to 43.4% in the first germination count and 16.3% in germination. The production and quality of sweet sorghum seeds reduces as a function of the increase in the interval between irrigations and the harvesting time, presenting germination rates below the required for commercialization.

Abstract Background Takayasu's arteritis (TA) is a vasculitis that affects the aorta and its branches and causes stenosis, occlusion, and aneurysms. Up to 60% of TA patients are associated with cardiac involvement which confers a poor prognosis. Global longitudinal strain (GLS) analysis is an echocardiographic technique that can detect the presence of subclinical systolic dysfunction. Hence, this study aimed to describe the prevalence of subclinical systolic dysfunction in patients with TA using the GLS method and to correlate this finding with disease activity using the ITAS-2010 (Indian Takayasu Activity Score). Methods Thirty patients over 18 years of age who met the American College of Rheumatology (ACR) 1990 criteria for TA were included. The sample was submitted for medical record review, clinical and echocardiographic evaluation, and application of ITAS-2010. The cutoff for systolic dysfunction was GLS > - 20%. Results Of the 30 patients analyzed, 25 (83.3%) were female, and the mean age was 42.6 years (± 13.2). The median time since diagnosis was 7.5 years [range, 3-16.6 years], and the type V angiographic classification was the most prevalent (56.7%). Regarding echocardiographic findings, the median ejection fraction (EF) was 66% [61-71%] and the GLS was - 19.5% [-21.3 to -15.8%]. Although half of the participants had reduced GLS, only two had reduced EF. Eleven patients (33.%) met the criteria for activity. An association was found between disease activity and reduced GLS in eight patients (P = 0.02) using the chi-square test. Conclusion GLS seems to be an instrument capable of the early detection of systolic dysfunction in TA. The association between GLS and disease activity in this study should be confirmed in a study with a larger sample size.

Abstract Alcohol has been widely consumed for centuries and is linked to the aggravation of diseases. Several studies have shown that excessive consumption of ethanol results in morphophysiological changes in the male reproductive system. One of the effects of ethanol is the decrease in testosterone concentration and hormonal therapies are an alternative to minimize the changes resulting from chronic alcoholism. Qualitative studies were commonly carried out to evaluate the male histopathological alterations resulting from ethanol consumption, being necessary quantitative and non-subjective techniques. This study analyzes the importance of fractal analysis as a useful tool to identify and quantify tissue remodeling in rats submitted to ethanol consumption and hormone therapy with testosterone. Prostate of animals submitted to chronic ethanol consumption showed tissue disorganization, which was confirmed by an increasing of fractal dimension. Regarding the prostatic stroma, collagen fractal dimension and quantification revealed lower values in animals that were only submitted to androgen therapy. Thus, we can conclude that the fractal analysis was a useful tool to quantify tissue changes caused by ethanol consumption and androgen therapy. diseases system alcoholism nonsubjective non subjective techniques disorganization stroma Thus

Abstract Propolis is a resinous product collected by honeybees with a complex chemical composition. Sodium carboxymethylcellulose is a polymer commonly used in wound care. The goal of the present work was to produce and characterize NaCMC membranes loaded with extract of Brazilian brown propolis (CMC-P). Flavonoids and phenolic acids were identified in the propolis extracts, where the main identified substance was kaempferide. The brown propolis extracted was active against S. aureus. The low swelling capacity and high gel fraction of CMC-P would be the consequence of propolis (responsible for a hydrophobic barrier) filling the pores of the membrane. Propolis could be anchoring the NaCMC chains (as observed by FTIR) due to interaction between components, which is corroborated by the CMC-P sample degrading less than the CMC sample (>400ºC). There was non-linear diffusion release kinetics for most phenolic substances of the propolis extract. The CMC-P sample presents potential as a dressing material.

Abstract Background: It is estimated that more than 30% of the Brazilian population has systemic arterial hypertension (SAH), and mostly as an uncontrolled disease. The most recent Brazilian Guideline of Hypertension recommends the practice of self-measurement of blood pressure (BP) as one of the strategies for a better control of SAH, but there is no consensus about the efficiency of this tool. Objective: To assess the control of SAH and the practice of non-targeted self-measured BP (SMBP) among hypertensive users of the Unified Health System (SUS) and the Supplementary Network (SN). Methods: This is a cross-sectional, observational, analytical study, with a stratified probability sample. One thousand volunteers were investigated, being 500 from SUS and 500 from the SN. Uni and multivariate analyses were performed considering a 5% significance level. Results: Patients from SUS presented inferior sociodemographic data (schooling, social status) in relation to those of the SN (p < 0.001), and showed lower control of SAH (p = 0.014), as well as more visits to the emergency room in the past year due to hypertension (p = 0.002), and fewer regular appointments with the cardiologist (p = 0.004). SMBP was equally present in both assessed groups (p = 0.567), even though users of the SN have been more advised to not conduct such a practice (p = 0.002). SMBP (p < 0.001) was an independent factor for uncontrolled SAH both in SUS (OR = 3.424) and in the SN (OR = 3.474). Conclusion: Patients in SUS presented lower SAH control. The practice of SMBP, mostly practiced with an uncalibrated digital device, was equally present in both groups and became an independent factor of uncontrolled SAH.
