Biosensors Based on Stanniocalcin-1 Protein Antibodies Thin Films for Prostate Cancer Diagnosis.

Prostate cancer is one of the most prevalent tumors in men, accounting for about 7.3% of cancer deaths. Although there are several strategies for diagnosing prostate cancer, these are only accurate when the tumor is already at a very advanced stage, so early diagnosis is essential. Stanniocalcin 1 (STC1) is a secreted glycoprotein, which has been suggested as a tumor marker as its increased expression is associated with the development and/or progression of different types of malignant tumors. In this work, an electronic tongue (ET) prototype, based on a set of four sensors prepared from thin films that included STC1 antibodies for detecting prostate cancer, was developed. In the preparation of the thin films, polyelectrolytes of polyallylamine hydrochloride, polystyrene sulfonate of sodium and polyethyleneimine, and the biomolecules chitosan, protein A, and STC1 antibody were used. These films were deposited on quartz lamellae and on solid supports using layer-on-layer and self-assembly techniques. The deposition of the films was analyzed by ultraviolet-visible spectroscopy, and the detection of STC1 in aqueous solutions of PBS was analyzed by impedance spectroscopy. The impedance data were statistically analyzed using principal component analysis. The ETs formed by the four sensors and the three best sensors could detect the antigen at concentrations in the range from 5 × 10-11 to 5 × 10-4 M. They showed a linear dependence with the logarithm of the antigen concentration and a sensitivity of 5371 ± 820 and 4863 ± 634 per decade of concentration, respectively. Finally, the results allow us to conclude that this prototype can advance to the calibration phase with patient samples.

Use of ergogenic aids among Brazilian athletes: a cross-sectional study exploring competitive level, sex and sports.

Was investigated ergogenic aids (EAs) used by Brazilian athletes and their association with performance, sex, sports classification, and modality. It identified the main purposes of EAs and their prescription. Methods: 239 athletes of 15 modalities, ranging from regional to international level, answered a survey online. Results: Highly competitive athletes consumed nutritional and mechanical aids more (OR = 1.96 CI 95% [1.28-2.9]; OR = 1.79 CI 95% [1.29-2.47]), while the use of psychological EAs decreased [OR = 1.66 95% CI (1.18-2.94); p = 0.001]. Male athletes [OR = 1.44 CI 95% (1.11-2.88)] and individual sports practitioners [OR = 1.78 CI 95% (1.02-3.11)] used nutritional aids more. Triathlon athletes had higher nutritional EA use, while soccer athletes had lower. Combat sports athletes had higher pharmacological EA use. Conclusion: Athletes use nutritional and pharmacological aids more to improve performance and gain lean body mass. Mechanical aids were used for recovery and psychological aids for motivation. Self-prescription is common, especially for pharmacological aids.

Global research publications on cardiovascular and pulmonary rehabilitation and their alignment with population rehabilitation needs: An ecological study.

PURPOSE: Towards informing health research policy and planning, this article evaluates the relationship of the research publications in cardiac rehabilitation (CR) and pulmonary rehabilitation (PR) with the rehabilitation needs arising from cardiovascular diseases (except stroke) and chronic respiratory diseases, over time (1990-2017). METHODS: Ecological study using a secondary analysis and linear regressions of public domain data to associate two datasets of population-level data: (1) research publications for CR and PR (data from the PubMed database); and (2) global need for CR and PR (data from the Global Burden of Disease study). RESULTS: The percentage of both CR and PR publications (among total rehabilitation research) significantly decreased from 1990 to 2017 (both: p < 0.01). PR needs and research publications were aligned: around 5% of total rehabilitation needs and rehabilitation research. For CR needs (around 2%, but significantly increasing since 1990), we found a greater portion of CR research publications (6.5% or over). Finally, we found an inverse association among the percentage of CR research publications and CR needs (b = -6.08; r2  = 0.37, p = 0.001). CONCLUSION: The portion of CR and PR research (among total rehabilitation research) is declining over time. Yearly percentage of CR publications were greater than those of PR but for lower level of rehabilitation need, but the disparate trend was significantly decreasing over time. Population rehabilitation needs and their alignment with research volume must be one factor in the design of population-centred, equitable health research priorities.

A proposal to analyze the progression of non-dialytic chronic kidney disease by surrogate endpoints: introducing parametric survival models.

Introduction: Chronic kidney disease (CDK) progression studies increasingly use surrogate endpoints based on the estimated glomerular filtration rate. The clinical characteristics of these endpoints bring new challenges in comparing groups of patients, as traditional Cox models may lead to biased estimates mainly because they do not assume a hazard function. Objective: This study proposes the use of parametric survival analysis models with the three most commonly used endpoints in nephrology based on a case study. Estimated glomerular filtration rate (eGFR) decay > 5 mL/year, eGFR decline > 30%, and change in CKD stage were evaluated. Method: The case study is a 5-year retrospective cohort study that enrolled 778 patients in the predialysis stage. Exponential, Weibull, Gompertz, lognormal, and logistic models were compared, and proportional hazard and accelerated failure time (AFT) models were evaluated. Results: The endpoints had quite different hazard functions, demonstrating the importance of choosing appropriate models for each. AFT models were more suitable for the clinical interpretation of the effects of covariates on these endpoints. Conclusion: Surrogate endpoints have different hazard distributions over time, which is already recognized by nephrologists. More flexible analysis techniques that capture these relevant clinical characteristics in decision-making should be encouraged and disseminated in nephrology research.

Effective and efficient active learning for deep learning-based tissue image analysis.

MOTIVATION: Deep learning attained excellent results in digital pathology recently. A challenge with its use is that high quality, representative training datasets are required to build robust models. Data annotation in the domain is labor intensive and demands substantial time commitment from expert pathologists. Active learning (AL) is a strategy to minimize annotation. The goal is to select samples from the pool of unlabeled data for annotation that improves model accuracy. However, AL is a very compute demanding approach. The benefits for model learning may vary according to the strategy used, and it may be hard for a domain specialist to fine tune the solution without an integrated interface. RESULTS: We developed a framework that includes a friendly user interface along with run-time optimizations to reduce annotation and execution time in AL in digital pathology. Our solution implements several AL strategies along with our diversity-aware data acquisition (DADA) acquisition function, which enforces data diversity to improve the prediction performance of a model. In this work, we employed a model simplification strategy [Network Auto-Reduction (NAR)] that significantly improves AL execution time when coupled with DADA. NAR produces less compute demanding models, which replace the target models during the AL process to reduce processing demands. An evaluation with a tumor-infiltrating lymphocytes classification application shows that: (i) DADA attains superior performance compared to state-of-the-art AL strategies for different convolutional neural networks (CNNs), (ii) NAR improves the AL execution time by up to 4.3×, and (iii) target models trained with patches/data selected by the NAR reduced versions achieve similar or superior classification quality to using target CNNs for data selection.

Relação entre as desordens temporomandibulares e a presença de distúrbios respiratórios crônicos: uma revisão sistemática da literatura / eraturaRelationship between temporomandibular disorders and the presence of chronic respiratory disorders: a systematic literature review

Introdução: As desordens temporomandibulares (DTM) são um grupo de patologias com implicação direta no entendimento das comorbidades que podem envolver o sistema estomatognático. Tal grupo patológico apresenta característica multifatorial e, por isso, tem sido observada sua possível relação com acometimentos sistêmicos, como problemas articulares, psicológicos e, mais especificamente, os distúrbios respiratórios crônicos (DRC). Objetivo: Conduzir uma revisão sistemática da literatura, utilizando ferramentas com validação metodológica, a fim de fornecer dados relevantes acerca da relação entre as DTM e os DRC. Metodologia: Foram pesquisadas as bases de dados MedLine/PubMed, Colaboração Cochrane, Plataforma Capes, Biblioteca Virtual em Saúde, Scopus, Web of Science e SciElo, cobrindo o período de 2000 a 2021 e utilizando a combinação dos descritores "temporomandibular disorders and breathing and pain and mouth breathing". Resultados: Após a busca, que culminou em 698 documentos encontrados, apenas 12 foram selecionados a partir dos critérios de elegibilidade predefinidos. No tocante à relação entre a presença de DTM e o diagnóstico de apneia obstrutiva do sono (AOS), foram encontrados 45 indivíduos com essa associação, reportados por dois estudos. É relatado, também, acometimento por infecções de vias áreas superiores associadas às DTM (7.012 indivíduos reportados), além de diagnóstico de respiração bucal em pacientes que apresentavam o diagnóstico de DTM (30 indivíduos reportados). Conclusão: A associação entre desordens do sono relacionadas à respiração, respiração bucal, AOS e dor relacionada à ATM foi fundamentada por alguns autores, destacando a influência desses parâmetros na qualidade de vida dos indivíduos. Observou-se, ainda, que esses acometimentos podem influenciar a postura do indivíduo, a qual está diretamente relacionada com a sintomatologia das DTM, principalmente pela ocorrência de anteriorização da cabeça.

Introduction: Temporomandibular disorders (TMD) are a group of pathologies that directly affect the understanding of comorbidities that may appear in the stomatognathic system. This group of pathologies has a multifactorial characteristic and, therefore, it has been observed a possible relation with systemic disorders, such as joint and psychological problems and, more specifically, chronic respiratory disorders (CRD). Objective: To conduct a systematic review based on reliable scientific web tools, in order to provide relevant data on the relation between TMD and CRD. Methods: MedLine/PubMed, Collaboration Cochrane, Plataforma Capes, Biblioteca Virtual em Saúde, Scopus, Web of Science and SciElo were searched in order to retrieve scientific articles, covering the period from 2000 to 2021. It was used the following combination of the descriptors: "temporomandibular disorders and breathing and pain and mouth breathing". Results: After the search, which resulted in 698 documents found, 12 were selected based on the pre-defined eligibility criteria. Regarding the relationship between TMD and the diagnosis of obstructive sleep apnea (OSA), there were found 45 individuals with this association, reported by two studies. It was also reported the involvement of upper airway infections in TMD (7,012 individuals reported). Furthermore, the search found patients diagnosed with TMD which were also diagnosed with mouth breathing (30 individuals reported). Conclusion: Some of the authors supported the combination between sleep disorders related to breathing, sleep quality and TMJ related pain, highlighting the influence of these parameters on quality of life. It was also observed that, even though the breathing pattern and its influences are a subject that is rarely mentioned in relation to TMD, this involvement can influence the individual's posture, which is directly related to the TMD symptomatology, mainly due to the occurrence of forward head posture.

Building Efficient CNN Architectures for Histopathology Images Analysis: A Case-Study in Tumor-Infiltrating Lymphocytes Classification.

Background: Deep learning methods have demonstrated remarkable performance in pathology image analysis, but they are computationally very demanding. The aim of our study is to reduce their computational cost to enable their use with large tissue image datasets. Methods: We propose a method called Network Auto-Reduction (NAR) that simplifies a Convolutional Neural Network (CNN) by reducing the network to minimize the computational cost of doing a prediction. NAR performs a compound scaling in which the width, depth, and resolution dimensions of the network are reduced together to maintain a balance among them in the resulting simplified network. We compare our method with a state-of-the-art solution called ResRep. The evaluation is carried out with popular CNN architectures and a real-world application that identifies distributions of tumor-infiltrating lymphocytes in tissue images. Results: The experimental results show that both ResRep and NAR are able to generate simplified, more efficient versions of ResNet50 V2. The simplified versions by ResRep and NAR require 1.32× and 3.26× fewer floating-point operations (FLOPs), respectively, than the original network without a loss in classification power as measured by the Area under the Curve (AUC) metric. When applied to a deeper and more computationally expensive network, Inception V4, NAR is able to generate a version that requires 4× lower than the original version with the same AUC performance. Conclusions: NAR is able to achieve substantial reductions in the execution cost of two popular CNN architectures, while resulting in small or no loss in model accuracy. Such cost savings can significantly improve the use of deep learning methods in digital pathology. They can enable studies with larger tissue image datasets and facilitate the use of less expensive and more accessible graphics processing units (GPUs), thus reducing the computing costs of a study.

Reconstruction of Scalp Anterior Hairline with Tissue Expansion and Skin Flap.

Introduction: Cutaneous defects involving the frontal region and anterior hairline of the scalp can result from congenital or acquired conditions. The negative esthetic impact can cause disturbances in the psychic and social sphere of the patient, causing problems in interpersonal relationships and in the body image itself. The use of skin expanders is usually effective in this region due to the bone base providing support and stability for its use. Case Report: We describe the case of a 64-year-old woman submitted to reconstruction of the anterior hairline of the scalp due to scar sequelae after coronal rhytidoplasty followed by pustular erosive dermatosis. We used tissue expansion (50 mL of saline per week until it reached 300 mL) and advancement flap. Discussion/Conclusion: Scalp reconstruction also includes vascularized soft tissue coverage, acceptable cosmetic appearance, and minimal morbidity for the donor area. The correction of scalp scars must obey 2 basic principles: tissue similarity and natural capillary pattern (direction, angle, capillary growth, and proper capillary line design). Tissue expansion and skin flap techniques can successfully correct defects in extensive scarring alopecia such as in the presented case.

Efficacy and Safety of BCG Revaccination With M. bovis BCG Moscow to Prevent COVID-19 Infection in Health Care Workers: A Randomized Phase II Clinical Trial.

The Bacillus Calmette-Guérin (BCG) vaccine, which is widely used to protect children against tuberculosis, can also improve immune response against viral infections. This unicentric, randomized-controlled clinical trial assessed the efficacy and safety of revaccination with BCG Moscow in reducing the positivity and symptoms of COVID-19 in health care workers (HCWs) during the COVID-19 pandemic. HCWs who had negative COVID-19 IgM and IgG and who dedicated at least eight hours per week in facilities that attended to individuals suspected of having COVID-19 were included in the study and were followed for 7, 15, 30, 60, and 180 days by telemedicine. The HCWs were randomly allocated to a revaccinated with BCG group, which received the BCG vaccine, or an unvaccinated group. Revaccination with BCG Moscow was found to be safe, and its efficacy ranged from 30.0% (95.0%CI -78.0 to 72.0%) to 31.0% (95.0%CI -74.0 to 74.0%). Mycobacterium bovis BCG Moscow did not induce NK cell activation at 15-20 days post-revaccination. As hypothesized, revaccination with BCG Moscow was associated with a lower incidence of COVID-19 positivity, though the results did not reach statistical significance. Further studies should be carried out to assess whether revaccination with BCG is able to protect HCWs against COVID-19. The protocol of this clinical trial was registered on August 5th, 2020, at REBEC (Registro Brasileiro de Ensaios Clínicos, RBR-4kjqtg - ensaiosclinicos.gov.br/rg/RBR-4kjqtg/1) and the WHO (# U1111-1256-3892). The clinical trial protocol was approved by the Comissão Nacional de ética de pesquisa- CONEP (CAAE 31783720.0.0000.5078).

A Software Defined Radio Based Anti-UAV Mobile System with Jamming and Spoofing Capabilities.

The number of incidents between unmanned aerial vehicles (UAVs) and aircrafts at airports and airfields has been increasing over the last years. To address the problem, in this paper we describe a portable system capable of protecting areas against unauthorized UAVs, which is based on the use of low-cost SDR (software defined radio) platforms. The proposed anti-UAV system supports target localization and integrates effective jamming techniques with the generation of global positioning system (GPS) spoofing signals aimed at the drone. Real-life tests of the implemented prototype have shown that the proposed approach is capable of stopping the reliable reception of radionavigation signals and can also divert or even take control of unauthorized UAVs, whose flight path depends on the information obtained by the GPS system.

Introdução: O envelhecimento humanointerfere diretamente no desempenho doatletamaster, portanto, saber em que momento ocorre estedeclínio de desempenho se torna essencial para a otimização do esporte master. Objetivo: Objetivou-se analisar a taxa de declínio dos tempos de nadadores masters em diferentes categorias etárias (25 a 99 anos). Metodologia: Os dados dos até 8 primeiros colocados dos 50 e 800 metros nado livre de cada categoria participante do Campeonato Brasileiro Master de 2019 foram coletados, totalizando 281 entradas na água. Foi realizada análise descritiva e inferencial. Resultados e discussão: Os 50 metros livre foi a prova com maior número de entradas; observou-se na comparação recordes de categorias vs.recordes nacionaisque as maiores diferenças percentuais ocorreram, em geral, a partir dos 60 anos. Este resultado é similar ao da comparação das médias das entradas de cada prova vs. recorde da categoria. Ainda, ao comparar a média das entradas vs. categoria 25-9 anos observou-se no masculino, e no feminino, diferenças significativas com as categorias 65-9 anos até 85-9 anos. Nos 800 livre, maiores diferenças percentuais também foram observadas a partir dos 60 anos para recordes de categorias vs. recordes nacionais. Contudo, ao analisar as médias das entradas de cada prova vs. recordes de cada categoria e ao comparar as médias das entradas vs.categoria 25-9 anos, não se observoudiferenças significativas para o feminino, enquanto que para o masculino, esta diferença ocorreu a partir da categoria 60-4 anos. Conclusão: Concluiu-se que a queda de desempenho nas provas da natação master analisadas é influenciada, em parte pelo processo de envelhecimento, sexo e a competição de referência.

Introduction: Human aging directly interferes with the performance of the master athlete, therefore, knowing when this performance decline occurs becomes essential for the optimization of the master sport. Objective: The aim of the study was to analyze the decline rate of swimmer's performances in different age groups, from 25 years old to 99 years old, at freestyle events. Methodology: Data from up to the first eight places were collected in the 50 and 800 meters freestyle from each participating group from the 2019 Brazilian Master Championship, for a total of 281 entries into the water. Descriptive and inferential analysis were performed. Results and discussion: The 50 freestyle was the event with the highest number of entries; it was observed in the comparison of age group records vs. national records that the greatest percentage differences occurred, in general, from the age of 60 years old. This result is similar to the comparison of the entry averages of each test vs. age group record. Also, when comparing the average of entries vs. 25-9 years old, significant differences were observed in males, and females,from 65-9 years old to 85-9 years old. In the 800 freestyle, higher percentage differences were also observed from the age of 60 years old from age group records vs. national records. However, when analyzing the averages of the entries of each test vs. records of each group and when comparing the averages of entries vs. 25-9 years, there were no significant differences for females, while for males, this difference occurred from the 60-4 years old. Conclusion: It was concluded that the performance drop in the analyzed master swimming tests is influenced, in part, by the aging process, sex and the reference competition.

Introduccíon: El envejecimiento humano interfiere directamente en el rendimiento del atleta maestro, por lo tanto, saber cuándo se produce esta disminución del rendimiento se vuelve esencial para la optimización del deporte maestro.

Os treinadores responderam em relação a importância atribuída aos fatores antropométrico, físico-motor, técnico, tático, psicológico e socioambiental, numa escala Likert (1-nada importante e 5-extremamente importante) e a ordem de importância, considerando do 1º ao 6º mais importante. Avaliaram ainda a importância para o desempenho de velocistas, fundistas, saltadores, lançadores e provas combinadas. Resultados e discussão: a ordem de importância dos fatores de desempenho foi: 1º) Físico-motor, 2º) Técnico, 3º) Psicológico, 4º) Antropométrico, 5º) Tático e 6º) Socioambiental. O fator tático, entretanto, foi o mais importante para os fundistas e atletas de provas combinadas. Conclusão: a opinião dos treinadores revelou que as características físico-motoras, técnicas e psicológicas são, nesta ordem, os principais fatores determinantes do desempenho no atletismo. Porém, é preciso considerar as diferenças observadas em relação aos grupos de provas, pois cada um apresenta particularidades que caracterizam um perfil específico.

Introduction: Assessing sporting potential is an important step in discovering new talent and should use relevant performance predictors, which vary by modality. Objective: investigate the importance attributed by coaches to the determinants of performance in athletics, analyzing differences between the events groups. Methodology: Twelve Brazilian coaches participated (11 men, 83% from Minas Gerais, 75% had high-level experience and 42% from international titles). A questionnaire containing six factors and 51 performance indicators in athletics was applied. The coaches answered the importance attributed to anthropometric, physicomotor, technical, tactical, psychological and socio-environmental factors, on a Likert scale, being 1-nothing important and 5-extremely important. Then, they informed the order of importance of these factors for the performance in athletics, considering from the 1st to the 6th most important. Finally, they evaluated the importance of factors and performance indicators for sprinters, long-distance runners, jumpers, throwers and, track and field combined events. Results and discussion: The order of importance of the performance factors was: 1º) Physicomotor, 2º) Technical, 3º) Psychological, 4º) Anthropometric, 5º) Tactical and 6º) Socio-environmental. The tactical factor was the most important for the long-distance runners and athletes of combined events. Conclusion: In the opinion of the coaches, physicomotor, technical and psichologycal characteristics are, in this order, the main determinant factors of performance in athletics. However, it is necessary to consider the differences between events groups. Each event group shows particular characteristics that result in a specific profile.

Fatores de risco cardiovascular em estudantes de graduação de uma universidade pública federal: um estudo epidemiológico transversal / Cardiovascular risk factors in undergraduate students at a federal public university: a cross-sectional epidemiological study

Introdução: A identificação precoce dos fatores de risco cardiovascular é o primeiro passo na prevenção das doenças cardiovasculares, atualmente, a principal causa de mortes no Brasil. Esses fatores são divididos em modificáveis, como obesidade, sedentarismo, dieta inadequada, consumo excessivo de álcool, estresse, hipertensão arterial sistêmica e tabagismo, e, não modificáveis, como hereditariedade, idade e gênero. Objetivos: Avaliar a prevalência de fatores de risco cardiovascular entre universitários e correlacionar os hábitos referidos com sua autoavaliação em saúde. Métodos: Estudo epidemiológico de corte transversal, descritivo e exploratório, com características quantitativas, baseado na aplicação de questionário estruturado em 419 graduandos da Universidade Federal de Juiz de Fora, com análise estatística de medidas de frequência, tendência e dispersão. Resultados: A idade média dos entrevistados foi de 21,35 ± 3,28 anos, sendo 50,4% do gênero masculino e 49,6% do feminino. História familiar positiva para doença cardiovascular foi relatada por 11,9%. A prevalência de sedentarismo foi de 43,0%, 20,2% apresentavam sobrepeso, 5,9% obesidade, 15,8% valores pressóricos compatíveis com préhipertensão e 14,6% de hipertensão. O consumo de bebidas alcóolicas foi relatado por 72,3%, tabagismo por 14,3% e drogas ilícitas por 18,3%, além do uso contínuo de medicamentos por 23,7%. Alimentação inadequada e alto nível de estresse foram identificados em 53,8% e 66,2%, respectivamente. Conclusão: Foram encontrados elevados índices de fatores de risco cardiovascular como hábitos alimentares inadequados, altos níveis de estresse, consumo de drogas ilícitas e IMC aumentado, que aliados à elevada prevalência de uso contínuo de medicamentos, demonstraram intrínseca relação negativa com a autoavaliação em saúde.

Introduction: Early identification of cardiovascular risk factors is paramount in preventing cardiovascular diseases, the main cause of death in Brazil. Those factors are divided into modifiable, such as obesity, sedentary lifestyle, inadequate diet, excessive alcohol consumption, stress, systemic arterial hypertension and smoking, and nonmodifiable, such as heredity, age and gender. Objectives: To assess the prevalence of cardiovascular risk factors among university students, correlating it with their habits and their self-rated perception about their health. Methods: Cross-sectional, descriptive and exploratory epidemiological study, with quantitative characteristics, based on the application of a structured questionnaire to 419 undergraduates at the Federal University of Juiz de Fora, with statistical analysis of frequency, trend and dispersion measures. Results: The average age of respondents was 21.35 ± 3.28 years, 50.4% male and 49.6% female. Positive family history of cardiovascular disease was reported by 11.9%. The prevalence of sedentary lifestyle was 43.0%, 20.2% of them were overweight, 5.9% obese, 15.8% had a blood pressure compatible with pre-hypertension and 14.6% with hypertension. The consumption of alcohol was reported by 72.3%, smoking by 14.3% and the use of illegal drugs by 18.3%, the continuous use of medication was highlighted by 23.7%. Inadequate nutrition and high levels of stress were identified in 53.8% and 66.2%, respectively. Conclusion: High levels of cardiovascular risk factors were found, such as inadequate eating habits, high levels of stress, consumption of illicit drugs and increased BMI, which, with the high prevalence of continuous use of medication, showed a worse self-rated perception about health.
