RESUMO
OBJECTIVE: The aim of this study was to conduct a detailed geospatial analysis of mobile phone signal coverage in the northwest macro-region of Paraná State, Brazil, seeking to identify areas where limitations in coverage may be related to lengthy travel times of the helicopter emergency medical service (HEMS) for the assistance of victims of road traffic injuries (RTIs). METHODS: An observational study was conducted to examine mobile phone signal coverage and HEMS travel times from 2017 to 2021. HEMS travel times were categorized into four groups: T1 (0-15 min), T2 (16-30 min), T3 (31-45 min), and T4 (over 45 min). Empirical Bayesian Kriging was used to map areas with low mobile signal coverage. The Kruskal-Wallis test and Dwass-Steel-Critchlow-Fligner comparative analyses were performed to explore how mobile signal coverage relates to HEMS travel times to RTI locations. RESULTS: There were 470 occurrences of RTIs attended by HEMS, of which 108 (23%) resulted in on-site fatalities. Among these deaths, 47 (26.85%) occurred in areas with low mobile phone signal coverage ("shadow areas"). Low mobile phone signal coverage identified at 175 (37.24%) RTIs locations, was unevenly distributed across the macro-region. The lowest medians of mobile signal quality were predominantly found in areas with HEMS travel times exceeding 30 min, corresponding to signal strength values of -98.44 (T3) and -100.75 (T4) dBm. This scenario represents a challenge for effective communication to activate HEMS. In the multiple comparison analysis among travel time groups, significant differences were observed between T1 and T2 (p < 0.001), T1 and T3 (p < 0.001), T1 and T4 (p < 0.001), and T2 and T3 (p < 0.001), indicating a potential association between lower mobile phone signal coverage and longer HEMS travel times. CONCLUSION: It can be concluded that poor mobile phone signals in remote areas can hinder HEMS activation, potentially delaying the start of treatment for RTIs. Identification of the shadow areas can help communication and health managers in designing and implementing the necessary changes to improve mobile phone signal coverage and consequently reduce delays in the initial response to RTIs.

The objective of this study was to characterize calvings with low and high difficulty based on the productive and reproductive performance of dairy cows. Calvings were grouped in no calving assistance, calving with low assistance, and calving with high assistance. The original data set comprised 1,902 calving records obtained from a large dairy farm in Southeast Brazil. Factor analysis was applied using the SAS® Studio 3.8 statistical program through the factor procedure, considering the Multivariate Analysis category. Milk fat (0.92-0.79) and total solids (0.91-0.80) were strongly correlated with Factor 1. Calving interval (0.87- 0.68) and the number of AI (artificial inseminations) per conception (0.87-0.71) showed high correlations with Factor 2. Milk yield (0.84-0.76) and accumulated milk yield (0.84-0.77) were strongly correlated with Factor 3. Based on the results, we conclude that the three calving scenarios were characterized by well-defined and independent factors. Cows which required a high assistance at calving showed a lower variance explained by the model for milk fat and total solids contents, calving interval, and the number of AIs per conception.
O objetivo deste estudo foi caracterizar os partos com leve ou severa dificuldade e diferenciá-los com base no desempenho produtivo e reprodutivo de vacas leiteiras. Os partos foram agrupados em partos sem assistência, partos com baixa assistência e partos com elevada assistência. O banco de dados original continha 1902 registro de partos que foram obtidos de uma grande fazenda comercial localizada no Sudeste do Brasil. A análise fatorial foi aplicada através do programa estatístico SAS® Studio 3.8 por meio de procedimento fatorial, considerando a categoria de análise multivariada. Os teores de gordura do leite (0,92- 0,79) e de sólidos totais (0,91-0,80) foram altamente correlacionados com o fator 1. Intervalo entre partos (0,87-0,68) e número de IA (inseminações artificiais) por concepção (0,87-0,71) apresentaram alta correlação com o fator 2. Produção de leite (0,84-0,76) e produção acumulada de leite (0,84-0,77) foram altamente correlacionados com o fator 3. Baseados nos resultados, é possível concluir que as três situações de parto foram caracterizadas por fatores independentes e bem definidos. Vacas que necessitaram de alta assistência ao parto apresentaram menor variância explicada pelo modelo para teores de gordura e sólidos totais do leite, intervalo entre partos e número de IA por concepção.

RESUMO
The aim of this study were (1) to characterize the growth curve in male and female cats, (2) to associate the growth and metabolizable energy intake (MEI) as an indirect measurement of the energy requirements, and (3) to determine the short-term effects of neutering on energy intake to maintain the bodyweight in young adult cats. Eighteen 5-months-old mixed breed cats were used in this study (males, n = 7 and BWâ¯=â¯2.2 ± 0.21 kg; females, nâ¯=â¯11 and BWâ¯=â¯2.0 ± 0.16 kg). The cats were fed to supply their metabolizable energy requirement for growth, adjusting the amounts to maintain an ideal body condition score. The animals were weighed every 15 days for 10 months (from 5 to 15 months old). At 12 months old, the cats were gonadectomized and the MEI was recorded for 3 months, up to 15 months old. Second-order, Gaussian, and spherical models were fitted to growth data. Male cats had higher energy intake for growth (MEIâ¯=â¯176.27-0.037t, R2â¯=â¯0.79) than females (MEIâ¯=â¯166.86-0.044t, R2â¯=â¯0.62), where t is the age in months. Male cats also reached mature weight later than female cats (16 and 13 months old, respectively). Neutering reduced the energy requirements of male (intact - 116.43 kcal/kg0.67; gonadectomized - 98.65 kcal/kg0.67; P < .01) and female cats (intact - 98.65 kcal/kg0.67; gonadectomized - 76.16 kcal/kg0.67; P < .01) on average 17.6%. This study suggests that in cats, males and females present different energy requirements since the early growth phases and, this difference remains after neutering in young adults. Female cats reach adult weight earlier than males.

Our goal was to evaluate the root development of flaxseed and its relationship with soil aggregation and organic carbon storage in two sowing seasons under soil conservationist management, in Santa Catarina state, Brazil. We used three flaxseed genotypes: Aguará and Caburé from Argentina, and Gold from Brazil, sowings in April and May in a no-tillage system under Haplumbrept. In the flowering stage, the root system was evaluated by image analyze using a Safira software. Root distribution maps were used by geostatistical kriging. At the harvest stage, soil blocks were sampled for analyze the aggregates morphometry by image with Quantporo software and the soil organic carbon. Undisturbed soil were sampled to determine the physical attributes. The experimental design was in randomized blocks with three repetitions, anova was performed by Fisher and the means compared by Tukey test. No physical impediments were found for the roots performance in the Haplumbrept under conservationist management system, these favored the irregularity of the aggregates surface observed by the low values of aspect and roughness in the different tested diameter ranges. Both Caburé and Aguará genotypes showed good roots spatial distribution in the soil profile in both sowing seasons with an increase in carbon storage in the smallest diameter aggregates (here considered the aggregates of 4.76-1 mm)...(AU)
O objetivo do trabalho foi avaliar o desenvolvimento radicular da linhaça e sua relação com a agregação do solo e o estoque de carbono em duas épocas de semeadura sob manejo conservacionista do solo, em Santa Catarina, Brasil. Foram utilizados três genótipos de linho: Aguará e Caburé-Argentina e Dourada-Brasil, semeados em abril e maio em sistema de plantio direto sobre Cambissolo Húmico. No estágio de floração, o sistema radicular foi avaliado por análise de imagem utilizando o programa Safira. Os mapas de distribuição radicular foram obtidos por krigagem - geoestatística. Na fase de colheita, foram amostrados blocos de solo para análise da morfometria de agregados por imagem no programa Quantporo além do carbono orgânico. Amostras de solo preservadas foram amostradas para determinar os atributos físicos. O delineamento experimental foi em blocos casualizados com três repetições, a anova foi realizada pelo teste de Fisher e as médias comparadas pelo teste de Tukey. Não foram encontrados impedimentos físicos para o desempenho das raízes no Cambissolo sob sistema de manejo conservacionista, favorecendo a irregularidade da superfície dos agregados observada pelos baixos valores de aspecto e rugosidade nas diferentes faixas de diâmetro testadas. Os genótipos Caburé e Aguará apresentaram boa distribuição espacial das raízes ao longo do perfil do solo em ambas as épocas de semeadura, com um aumento no armazenamento de carbono nos agregados de menor diâmetro (considerados aqui os agregados de 4,76-1 mm). O genótipo Caburé se adaptou às condições edafoclimáticas avaliadas, pois apresentou melhor desempenho radicular abaixo de 0,15 m.(AU)

Vegetables are important in economic, social, and nutritional matters in both the Brazilian and international scenes. Hence, some researches have been carried out in order to encourage the production and consumption of different species such as nonconventional vegetables. These vegetables have an added value because of their nutritional quality and nostalgic appeal due to the reintroduction of these species. For this reason, this article proposes the use of the machine learning technique in the construction of models for supervised classification and identification in an experiment with five leafy special of nonconventional vegetables (Tropaeolum majus, Rumex acetosa, Stachys byzantina, Lactuca cf. indica e Pereskia aculeata) assessing the characteristics of the macro and micro nutrients. In order to evaluate the classifiers' performance, the cross-validation procedure via Monte Carlo simulation was considered to confirm the model. In ten replications, the success and error rates were obtained, considering the false positive and false negative rates, sensibility, and accuracy of the classification method. Thus, it was concluded that the use of machine learning is viable because it allows the classification and identification of nonconventional vegetables using few nutritional attributes and obtaining a success rate of over 89% in most of the classifiers tested.

The objective of this investigation was to evaluate the activity of the suprahyoid musculature during swallowing and to correlate the findings with the degree of megaesophagus, oral and pharyngeal videofluoroscopy and esophageal manometry in patients with achalasia caused by Chagas' disease. Twenty-nine patients with positive serology for Trypanosoma cruzi and dysphagia (Chagas' disease group) and 29 individuals matched by sex and age (control group) participated in the study. Surface electromyography of the suprahyoid musculature and videofluoroscopy during swallowing of paste and liquid consistencies were performed. Canonical correlation analysis of the MANOVA test results showed that the Chagas' disease group had lower electromyographic activity when compared with controls. Overlapping circles of radiological findings were found for megaesophagus. The Spearman test showed a positive correlation between the electromyographic activity in the maximum voluntary isometric contraction and the time of pharyngeal transit for both liquid (p = 0.014) and paste (p = 0.047). The logistic regression test showed no association between electromyographic activity of the suprahyoid muscles and esophageal manometry results (p > 0.05). In conclusion, individuals with chagasic megaesophagus have reduced electromyographic activity of the suprahyoid muscles during swallowing, in addition to a greater recruitment of the suprahyoid musculature with increased pharyngeal transit time.

INTRODUCTION: Patients who require prolonged endotracheal intubation (>48 hours) are at risk of dysphagia. Speech-language pathologists should perform swallowing exercises after extubation due to the high probability of developing aspiration pneumonia. There are no studies describing the use of swallowing techniques employed in post-extubation therapy aided by surface electromyography. OBJECTIVES: To evaluate the effects of swallowing function therapy in extubated patients after prolonged orotracheal intubation by means of clinical and electromyographic evaluation. METHODS: A total of 15 patients were enrolled in this study (average age 48.6 ± 16.5 years). The study was carried out in three phases: (1) Clinical and electromyographic evaluation using the Dysphagia Risk Assessment Protocol following dysphagia scores criteria, and the measurement of the suprahyoid muscles amplitude (µV) expressed by root mean square (RMS), respectively; (2) swallowing rehabilitation program; and (3) reevaluation of patients after therapy. The Wilcoxon paired test assuming a significance level of 5% was used for statistical analysis. RESULTS: By means of the swallowing scale, it was verified that patients suffered from severe oropharyngeal dysphagia at the first evaluation (80%), but the rehabilitation therapy reduced clinical signs, persistent only in one patient (6.7%) post-therapy, thus, improving swallowing. Significant differences, pre- and post-therapy, for suprahyoid muscles during maximal voluntary isometric contractions of right (P = .0067) and left (P = .0215), saliva swallowing by right (P = .0413) and left (P = .0151), and liquid swallowing by right (P = .0479) and left (P = .0215) sides, were found, as shown by electromyography. CONCLUSIONS: Swallowing exercises carried out by extubated patients after prolonged orotracheal intubation increased neuromuscular recruitment of suprahyoid muscles involved with swallowing and reduced dysphagia levels.
RESUMO
This research was carried out to evaluate the royal jelly production in two trials. In Trial I, three genotypes of Africanized honeybees (Apis mellifera L.) were submitted to royal jelly production with two types of cups of different size and volume (conventional and Chinese model) and two types of supplements (commercial and formulated). A total of 24 colonies were used, two bars with different cups each, alternating between the upper or lower position of the frame. While in Trial II, 18 colonies, two genotypes, two types of cups and two types of supplement were tested. The evaluated parameters were: percentage of larvae accepted in upper and lower bars, royal jelly per cup (mg), and royal jelly per colony/collection (g). Chinese cups were not well accepted, fact that influenced in a negative way the production of general form, selected colonies were more sensible to the change of cups. Colonies of Africanized honeybees are not prepared to produce in cups of greater volume.(AU)

The objective of this research was to evaluate royal jelly production from Africanized honeybee queens of different lineages (lineage selected for honey production, lineage selected for royal jelly production and unselected) produced by single and double grafting and to compare royal jelly production among their offspring. Data were tested by double factorial analysis of variance and the means were compared by Tukey test at 5%. The parameters evaluated were: queen weight at emergence, percentage of larvae acceptance in the upper and lower bars, royal jelly per cup (mg) and royal jelly per colony/collection (g). Queens selected for honey presented greater weight at emergence, while the unselected queens were the lightest. Double grafting was better than simple grafting, since the queens were born 2.38% heavier. There was no difference (p > 0.05) in relation to royal jelly production according to neither the lineage nor even comparing the method by which the queens were produced. The cost of labor to produce queens by double grafting was much higher, as by the simple grafting about 170% more queens were born. The potential of Africanized honeybees with adequate production management and favorable environmental conditions favors the production of royal jelly.(AU)

The objective of this study is to analyze the typology of dairy production systems (DPS) in Paraná, Brazil, based on sustainable practices adopted by agricultural producers. A total of 153 semi-structured questionnaires containing variables for general characterization of DPS, socioeconomic characteristics of farmers, as well as environmental, social, and economic sustainability actions implemented by rural workers were applied. Common factor analysis (CFA) was used to evaluate sustainability variables. Three factors were created: economic (F1), social (F2), and environmental (F3). Hierarchical clusters were formed using the factor scores obtained in CFA. Three clusters were defined and were compared with F1, F2, and F3. There were significant differences in F1 and F2 between clusters 1, 2, and 3. Cluster 1 contained DPS highly compliant with economic, social, and environmental sustainability practices. Cluster 2 was defined by DPS with negative mean values for all three factors. Cluster 3 contained DPS that were highly compliant with F1 and F2 activities compared to cluster 2 and poorly compliant with F1 and F2 actions compared to cluster 1. Therefore, the DPS in Paraná vary according to the sustainable activities implemented by farm managers. In addition, most analyzed DPS have low survival capacity in the medium- and long-term. The most critical sustainability factor was F3, followed by F2 and F1.(AU)
Buscou-se analisar a tipologia de sistemas produtivos leiteiros (SPL) a partir de ações de sustentabilidade tomadas pelos produtores rurais nestes sistemas. Foram aplicados 153 formulários semiestruturados contendo variáveis de caracterização geral dos SPL, características socioeconômicas dos produtores de leite, bem como variáveis sobre as ações de sustentabilidade ambiental, social e econômica empregadas nestes sistemas. A técnica de análise fatorial comum (AFC) foi utilizada para gerar fatores de sustentabilidade. Três fatores foram gerados: econômico (F1), social (F2) e ambiental (F3). Em seguida, a partir dos scores fatoriais, foi empregada técnica de formação de clusters hierárquicos. Três clusters foram definidos e comparados frente a F1, F2 e F3. Foram identificadas diferenças para F1 e F2 entre os clusters 1, 2 e 3. O cluster 1 foi definido por SPL com os melhores resultados para as práticas de sustentabilidade econômica, social e ambiental. O cluster 2 foi definido por SPL com valores médios negativos para os três fatores. O cluster 3, foi definido por SPL com bons resultados para F1 e F2, frente aos SPL do cluster 2. Entretanto, o cluster 3 apresentou piores resultados quando comparado com o cluster 1. Foi identificada grande variabilidade nas ações de sustentabilidade empregadas nos SPL paranaenses analisados. A maior parte destes sistemas apresentou baixa adequação para a sustentabilidade. O fator de sustentabilidade mais crítico foi o ambiental, seguido pelo social e econômico.(AU)

BACKGROUND: Cutaneous leishmaniasis (CL) is endemic in the state of Paraná, Brazil. OBJECTIVE: This study aimed at analysing the influence of the remaining native vegetation on the prevalence of CL in Paraná. METHODS: Global testing was used for spatial autocorrelation along with simultaneous autoregressive model (SAR). The regression was based on the CL coefficient (cases/100,000 inhabitants) as a function of the percentage of natural vegetation cover, altitude, total number of cases, and spatial density (SD) per km2; the location data of the Paraná state municipalities and the detection coefficient (DC) (cases/100,000 inhabitants) of autochthonous cases of CL were obtained from the SINAN in 2012 and 2016. Data on the remaining forests were collected from the Fundação SOS Mata Atlântica and Instituto Nacional de Pesquisas Espaciais. FINDINGS: The spatial regression of DC revealed statistical significance for SD (Z = 24.1359, p < 0.05, 2012-2013; Z = 24.0817, p < 0.05, 2013-2014; Z = 33.4824, p < 0.05, 2014-2015; and Z = 27.1515, p < 0.05, 2015-2016. CONCLUSIONS: CL cases are reported in areas with native vegetation, such as in riparian forests. However, vegetation is not the only variable that influences the incidence of CL.

The objective of this study is to analyze the typology of dairy production systems (DPS) in Paraná, Brazil, based on sustainable practices adopted by agricultural producers. A total of 153 semi-structured questionnaires containing variables for general characterization of DPS, socioeconomic characteristics of farmers, as well as environmental, social, and economic sustainability actions implemented by rural workers were applied. Common factor analysis (CFA) was used to evaluate sustainability variables. Three factors were created: economic (F1), social (F2), and environmental (F3). Hierarchical clusters were formed using the factor scores obtained in CFA. Three clusters were defined and were compared with F1, F2, and F3. There were significant differences in F1 and F2 between clusters 1, 2, and 3. Cluster 1 contained DPS highly compliant with economic, social, and environmental sustainability practices. Cluster 2 was defined by DPS with negative mean values for all three factors. Cluster 3 contained DPS that were highly compliant with F1 and F2 activities compared to cluster 2 and poorly compliant with F1 and F2 actions compared to cluster 1. Therefore, the DPS in Paraná vary according to the sustainable activities implemented by farm managers. In addition, most analyzed DPS have low survival capacity in the medium- and long-term. The most critical sustainability factor was F3, followed by F2 and F1.
Buscou-se analisar a tipologia de sistemas produtivos leiteiros (SPL) a partir de ações de sustentabilidade tomadas pelos produtores rurais nestes sistemas. Foram aplicados 153 formulários semiestruturados contendo variáveis de caracterização geral dos SPL, características socioeconômicas dos produtores de leite, bem como variáveis sobre as ações de sustentabilidade ambiental, social e econômica empregadas nestes sistemas. A técnica de análise fatorial comum (AFC) foi utilizada para gerar fatores de sustentabilidade. Três fatores foram gerados: econômico (F1), social (F2) e ambiental (F3). Em seguida, a partir dos scores fatoriais, foi empregada técnica de formação de clusters hierárquicos. Três clusters foram definidos e comparados frente a F1, F2 e F3. Foram identificadas diferenças para F1 e F2 entre os clusters 1, 2 e 3. O cluster 1 foi definido por SPL com os melhores resultados para as práticas de sustentabilidade econômica, social e ambiental. O cluster 2 foi definido por SPL com valores médios negativos para os três fatores. O cluster 3, foi definido por SPL com bons resultados para F1 e F2, frente aos SPL do cluster 2. Entretanto, o cluster 3 apresentou piores resultados quando comparado com o cluster 1. Foi identificada grande variabilidade nas ações de sustentabilidade empregadas nos SPL paranaenses analisados. A maior parte destes sistemas apresentou baixa adequação para a sustentabilidade. O fator de sustentabilidade mais crítico foi o ambiental, seguido pelo social e econômico.

BACKGROUND Cutaneous leishmaniasis (CL) is endemic in the state of Paraná, Brazil. OBJECTIVE This study aimed at analysing the influence of the remaining native vegetation on the prevalence of CL in Paraná. METHODS Global testing was used for spatial autocorrelation along with simultaneous autoregressive model (SAR). The regression was based on the CL coefficient (cases/100,000 inhabitants) as a function of the percentage of natural vegetation cover, altitude, total number of cases, and spatial density (SD) per km2; the location data of the Paraná state municipalities and the detection coefficient (DC) (cases/100,000 inhabitants) of autochthonous cases of CL were obtained from the SINAN in 2012 and 2016. Data on the remaining forests were collected from the Fundação SOS Mata Atlântica and Instituto Nacional de Pesquisas Espaciais. FINDINGS The spatial regression of DC revealed statistical significance for SD (Z = 24.1359, p < 0.05, 2012-2013; Z = 24.0817, p < 0.05, 2013-2014; Z = 33.4824, p < 0.05, 2014-2015; and Z = 27.1515, p < 0.05, 2015-2016. CONCLUSIONS CL cases are reported in areas with native vegetation, such as in riparian forests. However, vegetation is not the only variable that influences the incidence of CL.
