ABSTRACT
HIV infection is a worldwide epidemic. Antiretroviral therapy allows people living with HIV (PLHIV) increased longevity and a better quality of life. Among the various ways of monitoring the clinical evolution of PLHIV, handgrip strength (HGS) is a promising strategy, as this test can be used to assess the health condition quickly and at a low cost. In this sense, the present study aims to describe, through a literature review, the relationship between HGS and the clinical evolution of PLHIV, especially with morbimortality. Initially, it is highlighted that aging, HIV infection, and excess body fat are related to the loss of HGS in PLHIV. Furthermore, PLHIV is more likely to present cardiometabolic diseases that can be aggravated by reduced HGS. Thus, in people without positive HIV serology, low HGS indirectly, through the presence of risk factors or cardiometabolic diseases, or directly increases the chance of mortality. In conclusion, the lack of studies on this topic for PLHIV is highlighted, and more longitudinal studies, including control groups, are needed.
ABSTRACT
BACKGROUND: The time elapsed since HIV infection diagnosis (TdiagHIV) affects the quality of life (QoL) and can get worse when chronic illnesses start. OBJECTIVE: The aim of this study was to analyze the impact of metabolic syndrome (MetS) and cardiovascular risk (CVR) on the QoL of people living with HIV (PLHIV). METHODS: Cross-sectional study, with 60 PLHIV followed at a Reference Center in the city of Jataí, Goiás, Brazil. Data collection involved sociodemographic, clinical, CVR, MetS, and QoL information. The data were analyzed using descriptive and inferential statistics, with the BioEstat 5.3 program adopting p0.05. RESULTS: There was a predominance of men (61.7%), aged ≥38 years (53.3%), with a TdiagHIV of 97.88Añ85.65 months and use of antiretroviral therapy (ART) of 80.13Añ69.37 months. The worst domain of QoL was concern about confidentiality (40 points), and the best was medication concerns (95 points). MetS predominated at 18.3% and a moderate CVR at 11.7%. MetS was positively associated with age 38 years, the female sex, with the lowest score in QoL for general function, and the highest for TdiagHIV and the use of ART (p0.05). A moderate CRV was positively related to higher TdiagHIV and ART use, and low HDL-c, and the lowest score for QoL was found for trust in a professional (p0.05). CONCLUSION: PLHIV who are older, have a higher TdiagHIV, and use ART are more likely to develop MetS and moderate CVR. The presence of these diseases in PLHIV causes impairment in areas of QoL.
ABSTRACT
Introduction: The change in handgrip strength (HGS) is an indicator of the emergence of some chronic diseases, such as diabetes mellitus (DM) and systemic arterial hypertension (SAH). Objective: Analyze the relationship between HGS and body composition and laboratory indicators of diabetic and hypertensive patients assisted in Primary Health Care. Methods: The sample consisted of 185 users of a Basic Health Unit in the city of Santarém, Pará, distributed into two groups: control (CTL) users without a diagnosis of DM and/or SAH (n=66); and DM/SAH (n=119) users with DM or SAH or both diseases. Data collection involved sociodemographic, clinical, anthropometric, biochemical, and HGS information. Data were analyzed using descriptive and inferential statistics, adopting p<0.05. Results: It was noted that low HGS in the DM/SAH group was associated with high values of body mass index, abdominal circumference, fat percentage, fat mass, total cholesterol, and triglycerides and with more factors for metabolic syndrome (p<0.05). The CTL group, in relation to DM/SAH for the same HGS classification, demonstrated significance for lower blood pressure values, body mass index, abdominal circumference, fat percentage, and fat mass, as well as a lower chance of developing metabolic syndrome (p<0.05). Conclusion: According to the study proposal, it is concluded that the evaluation and follow-up of HGS in individuals with chronic diseases, especially DM and SAH, is relevant to monitor body adiposity and dyslipidemia and avoid the aggravation of existing diseases or the emergence of new ones (AU).
Introdução: A alteração na força de preensão (FP) manual é indicador para surgimento de algumas doenças crônicas, como a diabetes mellitus (DM) e hipertensão arterial sistêmica (HAS). Objetivo: Analisar a relação da FP com a composição corporal e indicadores laboratoriais de diabéticos e hipertensos assistidos na Atenção Primária à Saúde. Métodos: A amostra foi composta por 185 usuários de uma Unidade Básica de Saúde na cidade de Santarém, Pará, sendo distribuídos em dois grupos: controle (CTL) usuários sem o diagnóstico para DM e/ou HAS (n=66); e DM/HAS (n=119) usuários com DM ou HAS ou as duas doenças. A coleta de dados envolveu informações sócio-demográficas, clínicas, antropométricas, bioquímicas e FP. Os dados foram analisados por estatística descritiva e inferencial, adotando-se p<0,05. Resultados: Notou-se que a FP baixa no grupo DM/HAS apresentou associação com valores elevados do índice de massa corporal, circunferência abdominal, percentual de gordura, massa gorda, colesterol total, triglicerídeos e com mais fatores para a síndrome metabólica (p<0,05). Já o grupo CTL, em rela-ção do DM/HAS para uma mesma classificação de FP, demonstrou significância para menores valores pressóricos, do índice de massa corporal, da circunferência abdominal, percentual de gordura, massa gorda, bem como menor chance para o desenvolvimento da síndrome metabólica (p<0,05). Conclusão: Conclui-se, conforme a proposta do estudo, que é relevante a avaliação e acompanhamento da FP em indivíduos com doenças crônicas, em especial a DM e a HAS, a fim de monitorar a adiposidade corporal e a dislipidemia, evitando o agravo das doenças instaladas ou o surgimento de novas (AU).

BACKGROUND: Handgrip strength (HGS) is an important health indicator that can be influenced by body composition and biochemical markers of people living with HIV, contributing to better understanding of health-related outcomes. OBJECTIVE: To analyze the relationship between HGS and health indicators in people living with HIV. METHODS: Cross-sectional study, with 207 people living with HIV, attending a reference center, located in Santarém, Pará, Brazil. Data collection covered sociodemographic, clinical, laboratory, physical activity level, body composition, and HGS information. Data were analyzed using descriptive and inferential statistics, adopting p < .05. RESULTS: There was a predominance of men (60%), aged 33-47 years (42%). A relationship was observed between adequate HGS and the male sex (p < .001), and adequate values for body mass index (p = .003), abdominal circumference (p < .001), and total cholesterol (p = .012). In addition, higher values of fat mass (p < .001), and lower lean mass (p = .006) were observed for people living with HIV with low HGS. CONCLUSION: People living with HIV present an association between lean body mass and high HGS. On the other hand, low HGS favored obesity and hypercholesterolemia. Thus, monitoring HGS is an important indicator of body, laboratory, and functional capacity changes, with HGS being an additional element in the clinical evaluation.

BACKGROUND: The study of aging and handgrip strength (HGS) is important to gain knowledge regarding health care and quality of life in people living with HIV (PLHIV). OBJECTIVE: The aim of the study is to analyze the relationship between HGS and age in the body composition variables of PLHIV. METHODS: The sample consisted of 77 PLHIV, divided into three groups: G40 - PLHIV aged 40-49 years (n=39); G50 - PLHIV aged 50-59 years (n=26); and G60 - PLHIV aged 60-69 years (n=12). Data collection included anamnesis (sociodemographic, clinical, and laboratory information), physical assessment (body composition and HGS), and physical activity level. Data were analyzed by descriptive and inferential statistics. RESULTS: It was noted that men, compared to women, are 5.85 times more likely to present adequate HGS (p<0.001). In addition, adequate HGS was associated with adequate values of body mass index (p<0.001), waist circumference (p<0.001), and fat percentage (p<0.001). The G40 and G50 groups, in relation to the G60, were associated with adequate abdominal circumference (p=0.04). CONCLUSION: Monitoring the evolution of HGS in PLHIV, over time, makes it possible to infer about body fat and muscle mass, in order to propose prevention actions and guidelines to prevent early muscle loss, the development of overweight/obesity, and abdominal obesity.

Introdução: os cuidados com os trabalhadores é uma importante questão de saúde pública. Objetivo: avaliar os efeitos da ginástica laboral (GL) na flexibilidade da coluna cervical e lombar de servidores do hospital universitário. Materiais e Métodos: trata-se de um estudo experimental. Participaram do estudo, 50 colaboradores distribuídos em dois grupos: Controle (CTL, n=25) e Experimental (EXP, n=25). O grupo CLT não participou das aulas de GL e o grupo EXP realizou 16 sessões de GL, quatro vezes por semana, por quatro semanas. A flexibilidade da coluna cervical e lombar dos participantes foi realizada em dois momentos, antes de iniciarem o programa de GL e após 16 sessões. Resultados: foi verificado que a prática de GL resultou em um aumento da flexibilidade cervical. Em relação à coluna lombar, o período de intervenção não impediu a redução da flexibilidade, no entanto, essa redução foi 50% menor no grupo EXP quando comparado ao grupo CTL. Conclusão: o programa de GL é uma estratégia de intervenção fundamental para a saúde do trabalhador, visto que a flexibilidade é um importante componente da atividade física relacionada à saúde.
Introduction: care of workers is an important public health issue. Objective: to evaluate the effects of occupational gymnastics (OG) on the flexibility of the cervical and lumbar spine of employees at the university hospital. Materials and Methods: this is an experimental study. A total of 50 employees participated in the study, divided into two groups: Control (CTL, n = 25) and Experimental (EXP, n = 25). The CLT group did not participate in the OG classes and the EXP group had 16 OG sessions, which took place four times a week, for four weeks. The flexibility of the cervical and lumbar spine of the participants was assessed in two moments, before starting the OG program and after 16 sessions. Results: it was observed that the practice of OG resulted in an increase in cervical flexibility. Regarding the lumbar spine, the intervention period did not prevent the reduction in flexibility; however, this reduction was 50% lower in the EXP group when compared to the CTL group. Conclusion: the OG program is a fundamental intervention strategy for workers' health, since flexibility is an important component of physical activity related to health.

Introduction: some plants such as turmeric, cinnamon, and okra are known to have therapeutic functions such as antioxidant and anti-inflammatory activity. Furthermore, an immunomodulatory role has been observed in the production of antibodies, in particular immunoglobulin A (IgA), which mediates a variety of protective functions for the organism. Objective: the aim of the present study was to investigate the effect of dietary plants on the production of IgA in healthy Wistar rats. Methods: thus, 48 male Wistar rats of 90 days of age were allocated to four groups. The animals were treated for 14 days with dried turmeric, cinnamon, or okra (50, 50, 12.5 mg/day, respectively) in phosphate buffered saline, or with only phosphate buffered saline by gavage. The animals received water and feed ad libitum. Body mass and relative weight ofperitoneal fat, adrenal gland, kidney, spleen, liver and thymus, biochemical parameters, and IgA levels were analyzed. Results: no significant changes were observed in the body mass, relative weight of organs and tissues, and biochemical parameters. An increase in serum IgA levels was observed in animals treated with turmeric or cinnamon. Conclusion: we conclude that the treatment with turmeric and cinnamon increased IgA production. Therefore, our study supports the idea that dietary supplementation with these plants may improve humoral immunity.
Introdução: algumas plantas como a cúrcuma, a canela e o quiabo são conhecidas por apresentar funções terapêuticas, como atividade antioxidante e anti-inflamatória. Além disso, tem sido observado um papel imunomodulador sobre a produção de anticorpos, em especial a imunoglobulina A (IgA), a qual medeia uma variedade de funções protetoras para o organismo. Objetivo: o objetivo do presente estudo foi investigar o efeito de plantas dietéticas na produção de IgA em ratos Wistar saudáveis. Métodos: destarte, 48 ratos machos Wistar com 90 dias de idade foram alocados em quatro grupos. Os animais foram tratados por 14 dias com cúrcuma seca, canela ou quiabo (50, 50, 12,5 mg/dia, respectivamente) em solução salina tamponada com fosfato ou apenas solução salina tamponada com fosfato, por gavagem. Os animais receberam água e ração ad libitum. Foram analisados a massa corporal e o peso relativo da gordura peritoneal, glândula adrenal, rim, baço, fígado e timo, parâmetros bioquímicos e níveis de IgA. Resultados: não foram observadas alterações significativas na massa corporal, no peso relativo dos órgãos e tecidos e nos parâmetros bioquímicos. Foi observado aumento dos níveis séricos de IgA nos animais tratados com cúrcuma ou canela. Conclusão: podemos concluir que o tratamento com cúrcuma e canela aumentou a produção de IgA. Portanto, nosso estudo suporta a ideia de que a suplementação alimentar com essas plantas pode melhorar a imunidade humoral.

Introdução: Alterações hematológicas, bioquímicas e imunológicas podem estar presentes no paciente infectado pelo HIV, no momento do diagnóstico, antes ou depois de iniciar com os antirretrovirais. Objetivo: Analisar o perfil bioquímico, hematológico e imunológico de pacientes com diagnóstico recente para HIV. Método: O estudo avaliou 321 prontuários de pacientes recém diagnosticados com a infecção pelo HIV. A coleta de dados envolveu informações sociodemográficas (data de nascimento, idade, sexo, escolaridade, estado civil, vínculo empregatício e procedência), clínicas (data do diagnóstico para a infecção pelo HIV, situação de imunodeficiência e tipo de exposição), bioquímicas (glicose, triglicerídeos, colesterol total e frações), hematológicas (hemoglobina e plaqueta) e imunológicas (linfócitos T CD4+ e carga viral). Os dados foram analisados por estatística descritiva e inferencial, adotando-se p<0,05. Resultados: Notou-se predominância do sexo masculino (67%), faixa etária de 18-27 anos (39,9%), solteiros (58,6%) e com 32% dos pacientes apresentando Aids. Das variáveis analisadas, o sexo masculino apresentou, em relação às mulheres, maior quantidade de hemoglobina e menores valores para contagem de linfócitos T CD4+, glicose e colesterol total (p<0,05). Além disso, ressalta-se que 69% da amostra apresentou alguma alteração lipídica, 96% tinha carga viral detectável e 29% apresentou linfócitos T CD4+ <200 cel/mm3. Conclusão: Pessoas vivendo com o HIV, no momento do diagnóstico, podem apresentar alterações imunológicas, hematológicas e bioquímicas, tornando imprescindível a avaliação, acompanhamento e orientação multiprofissional, tanto antes como posterior introdução dos antirretrovirais, a fim de evitar futuros agravos a saúde.

Introduction: Hematological, biochemical, and immunological alterations may already be present in HIV-infected patients at the time of diagnosis or before, or after starting antiretroviral therapy. Objective: Analyze the biochemical, hematological, and immunological profile of patients with a recent diagnosis of HIV. Method: The study evaluated 321 medical records of patients newly diagnosed with HIV infection. Data collection involved sociodemographic (date of birth, age, gender, education, marital status, employment relationship, and origin), clinical (date of diagnosis for HIV infection, immunodeficiency status, and type of exposure), biochemical (glucose, triglycerides, total cholesterol, and fractions), hematological (hemoglobin and platelet) and immunological (CD4+ T lymphocytes and viral load) information. Data were analyzed by descriptive and inferential statistics, adopting p<0.05. Results: There was a predominance of males (67%), aged 18-27 years (39.9%), single (58.6%), and 32% of patients had AIDS. Of the variables analyzed, males presented higher amounts of hemoglobin and lower values for CD4+ T lymphocyte count, glucose, and total cholesterol in relation to females (p<0.05). In addition, it is noteworthy that 69% of the sample presented a lipid alteration, 96% had a detectable viral load, and 71% had CD4+ T lymphocytes <200 cells/mm3. Conclusion: People living with HIV, at the time of diagnosis, may present immunological, hematological, and biochemical alterations, making multidisciplinary evaluation, follow up, and guidance essential, both before and after the introduction of antiretroviral therapy, in order to avoid future health problems.

ABSTRACT
Branched-chain amino acids (BCAA) are used as a recovery method after exercise-induced muscle damage (EIMD). Although data suggest that BCAA may alleviate the delayed-onset muscle soreness (DOMS) evoked by EIMD, there is no consensus about the most effective supplementation protocol. To investigate the effects of BCAA on DOMS after a single exercise session that caused EIMD, a systematic review and meta-analysis were conducted on the effectiveness of BCAA supplementation to reduce DOMS symptoms in healthy subjects after a single session of EIMD. Randomized clinical trials (RCT) were searched in Medline, Cochrane Library, Science Direct, SciELO, LILACS, SciVerse Scopus, Springer Link journals, Wiley Online Library, and Scholar Google, until May 2021. Ten RCTs were included in the systematic review and nine in the meta-analysis. Seven studies demonstrated that BCAA reduced DOMS after 24 to 72 h. BCAA doses of up to 255 mg/kg/day, or in trained subjects, for mild to moderate EIMD, could blunt DOMS symptoms. However, high variability between studies due to training status, different doses, time of treatment, and severity of EIMD do not allow us to conclude whether BCAA supplementation is efficient in untrained subjects, applied acutely or during a period of pre to post days of EIMD, and at higher doses (> 255 mg/kg/day). The overall effects of BCAA on DOMS after a single session of exercise were considered useful for improving muscle recovery by reducing DOMS in trained subjects, at low doses, in mild to moderate EIMD, and should not be administered only after the EIMD protocol.

A Anatomia da região cervical é de particular importância para os clínicos e cirurgiões de diversas especialidades médicas. Em se tratando da organização nervosa presente na região anterolateral do pescoço, encontra-se o plexo cervical, formado pelos ramos anteriores dos nervos cervicais C1 a C4, cuja função é promover a sensibilidade da pele anterolateral cervical, torácica anterossuperior e do couro cabeludo posterior, na cabeça, além de controlar a musculatura infra-hióidea e diafragmática. Logo, lesões a essa estrutura nervosa e aos seus ramos podem causar graves complicações ao corpo humano. Esse trabalho objetivou utilizar a dissecção da região anterolateral do pescoço como uma ferramenta pedagógica para o estudo das relações anatômicas dos nervos do plexo cervical observados durante essa prática, assim como relatar algumas de suas importâncias clínicas e cirúrgicas. O presente estudo é caracterizado como qualitativo/descritivo. A dissecção foi realizada semanalmente, durante o segundo semestre de 2018 e o primeiro semestre de 2019, com a supervisão do professor responsável e auxílio do técnico de laboratório, no Laboratório de aulas práticas da Universidade Estadual de Londrina (UEL). Considera-se que a dissecção da região anterolateral do pescoço permitiu a visualização de diversos nervos cutâneos e musculares do plexo cervical, assim como de alguns de seus ramos e suas relações anatômicas. Também contribuiu para o conhecimento da topografia em que se encontravam tais estruturas e sua organização em camadas. Esse conhecimento anatômico é essencial para a prática médica, tanto clínica quanto cirúrgica.(AU)
The anatomy of the cervical region is of particular importance for surgeons and physicians of different medical specialties. The cervical plexus can be found in the anterolateral region of the neck, formed by the anterior branches of the cervical nerves C1 to C4, whose function is to promote the sensitivity of the cervical anterolateral skin, anterosuperior thoracic skin, and posterior scalp, on the head, in addition to controlling the infrahyoid and diaphragmatic muscles. Therefore, injuries to this nervous structure and its branches may cause serious complications to the human body. This work aimed at using the dissection of the anterolateral neck region as a pedagogical tool for the study of the anatomical relationships of the cervical plexus nerves observed during this practice, as well as to highlight some of its clinical and surgical importance. This is a qualitative/descriptive study. The dissection was performed weekly, during the second semester of 2018 and the first semester of 2019, with the supervision of the professor in charge and the assistance of the laboratory technician at the Laboratory of Practical Classes at the State University of Londrina (UEL). It is considered that the dissection of the anterolateral neck region allowed the visualization of several cutaneous and muscular nerves present in the cervical plexus. It also contributed to the knowledge of the topography in which these structures were found and their organization in layers. This anatomical knowledge is essential for both clinical and surgical medical practice.(AU)

INTRODUCTION: The city of Santarém, the regional healthcare center in the western Pará State, lacks studies on the epidemic of the human immunodeficiency virus (HIV), in particular, on the causes of death. OBJECTIVE: To characterize the sociodemographic and clinical profile related to the evolution of HIV infection to death. METHODS: The sample consisted of 94 medical records of patients from a reference center in the city of Santarém-PA, who died between 2010-2018. Data were collected on the sociodemographic profile, immunological and clinical characteristics of the patients. Data were analyzed using descriptive and inferential statistics, adopting p<0.05. RESULTS: Most deaths were male (67%), aged between 15-29 years (39%) and diagnosed between 30-44 years (41%), single (54%), mixed race (91.5%), from Santarém (77%) and with sexual intercourse being the main type of exposure (95.7%). Most patients were not being treated at the moment of death (56.4%), the main cause of death was respiratory failure (5%), in which, these individuals had, at the moment of death, TCD4+ lymphocytes <200 cell/mm3 (26%) and detectable viral load (29%). CONCLUSION: The lifetime from diagnosis to death was 48.45±50,30 months, and immunosuppression in the diagnosis was positively associated with the shortest survival time. However, sex was not associated with the immunological profile, age at the time of diagnosis, and death. There was only a tendency for women towards immunosuppression and detectable viral load.
INTRODUÇÃO: A cidade de Santarém, o polo assistencial da região oeste do Pará, carece de estudos sobre a epidemia do vírus da imunodeficiência humana (HIV), especialmente, sobre as causas de óbitos. OBJETIVO: Caracterizar o perfil sociodemográfico e clínico relacionado à evolução da infecção pelo HIV até a morte. MÉTODO: A amostra foi de 94 prontuários de pacientes de um centro de referência do município de Santarém-PA, que evoluíram a óbito entre os anos de 2010-2018. Foram levantados os dados sobre o perfil sociodemográfico, características imunológicas e clínicas dos pacientes. Os dados foram analisados por estatística descritiva e inferencial, adotando-se p<0,05. RESULTADOS: A maioria dos óbitos foi de indivíduos do sexo masculino (67%), com faixa etária do diagnóstico entre 15-29 anos (39%) e de falecimento entre 30-44 anos (41%), solteiros (54%), pardos (91,5%), procedentes de Santarém (77%) e com a relação sexual sendo o principal tipo de exposição (95,7%). A maioria dos pacientes não estava em tratamento no momento do óbito (56,4%), a principal causa de morte foi por insuficiência respiratória (5%), no qual, esses indivíduos apresentavam, no momento da morte, linfócitos TCD4+ <200 cél/mm3 (26%) e carga viral detectável (29%). CONCLUSÃO: O tempo de vida do diagnóstico ao óbito foi de 48,45±50,30 meses e a presença de imunossupressão no diagnóstico associou-se positivamente com o menor tempo de sobrevida. Contudo, o sexo não apresentou associação com o perfil imunológico, a idade no momento do diagnóstico e do óbito, apenas notou-se uma tendência das mulheres para a imunossupressão e carga viral detectável.

Com a constante redução na carga horária destinada à AH e diante dos debates sobre os novos métodos de ensino, o uso do código de quick response (código QR) se mostrou promissor. Nesse sentido, foi desenvolvido no Departamento de Anatomia da Universidade Estadual de Londrina (UEL) o processo de catalogação das estruturas anatômicas com o uso do código QR, sendo nosso objetivo relatar esta experiência. Neste processo, as estruturas dissecadas no Laboratório de Anatomia da UEL foram catalogadas com base em uma planilha contendo a correlação entre estruturas e números e, as informações de cada estrutura transcritas em um código QR através de um gerador eletrônico, sendo então impresso, plastificado e anexado à peça anatômica. As marcações foram realizadas por meio da sutura de etiquetas enumeradas. Dentro da discussão dos métodos alternativos de ensino há como exemplos a plastinação, a projeção em três dimensões e a prospecção. Em destaque neste relato, o uso do código QR mostrou-se como uma alternativa válida na agregação de conhecimento nos currículos acadêmicos. Por meio das atividades empreendidas no processo de catalogação, foi possível, além da aquisição de mais tempo dedicado ao conhecimento teórico-prático em AH, ampliar a independência no estudo e no desenvolvimento de pesquisas. Dessa forma, tem-se a oportunidade de se expandir as análises voltadas ao ensino da AH e aos novos métodos de aprendizado.
The study of human anatomy is a relevant part of the curriculum of health course graduation students. Given the constant reduction of hours destinated to the study of Anatomy and the debates regarding new teaching methods, the use of the Quick Response Code (QR code) has shown to be promising. Therefore, the Anatomy Department at the State University of Londrina (UEL) has developed a cataloging process concerning anatomical structures with the application of QR code, and this paper has the purpose of reporting on such experience. In the process, the structures dissected in UEL's Anatomy Laboratory were cataloged based on a spreadsheet which contained the correlation between these structures and numbers; the information regarding each structure was then transcribed into a QR code using a digital generator, with posterior printing, lamination and attachment to the body part. The labels were made by sewing the numbered tags onto the structures. Within the discussion regarding alternative teaching methods, examples can be given regarding lamination, three-dimension projection and prospection. The use of the QR code has proven to be a valid alternative in aggregating knowledge to academic curriculum. Through the activities performed in the process of cataloging, it was possible not only to dedicate more time to the theorical and practical learning of human anatomy, but also to increase the independence in studying and developing research. Furthermore, there is an opportunity to expand the analysis directed toward human anatomy teaching and toward new learning methods.

This study aimed to characterize the main mechanisms of acquired antimicrobial resistance of 103 multidrug-resistant Acinetobacter baumannii isolated from bloodstream from 2006 to 2016 from a hospital in Londrina, Brazil. All 103 isolates were identified as A. baumannii by amplification of the blaOXA-51-like and rpoB genes. Mortality was observed in the majority (81.6%) of the patients. High non-susceptibility rates (100.0-10.7%) were obtained for the evaluated antimicrobials, including colistin, polymyxin B, and tigecycline, and most isolates were classified as extensively drug-resistant (78.6%). Carbapenemase production was observed in 92.2% of the isolates. All carbapenem-resistant isolates showed a carbapenem-hydrolyzing class D ß-lactamase being either blaOXA-23-like (97.9%) or blaOXA-143-like (2.1%). None of the isolates had the genes blaOXA-24-like, blaOXA-58-like, blaOXA-48, blaKPC, blaNDM, blaSPM-1, blaSIM-1, blaVIM, blaIMP, blaGIM, blaGES, mcr-1, qnrA, qnrB, qnrC, qnrS, and qnrVc. As a genetic context of the blaOXA-23-like gene, Tn2006 was predominated (86.0%), and Tn2008 was less frequent (12.9%). Isolates harboring the blaOXA-143-like gene showed the blaOXA-253-like variant. A polyclonal profile was observed among the A. baumannii isolates. The presence of the international clonal complexes CC113/79, CC109/1, CC110/25, and CC103/15 was detected, with prevalence of CC113/79 (38.8%). This study provides essential information to understand the antimicrobial resistance patterns of A. baumannii and can be used to strengthen infection control measures in our hospital. Also, the study reinforces the urgent need to develop stewardship programs to avoid the spread and potential outbreaks by this pathogen.

It was evaluated the effects of maternal treatment with the Trichilia catigua (ExTc) crude extract on the antibodies' production by their offspring. Female rats received ExTc or saline from the first day of pregnancy until the twenty-first day after the birth of the pups, when the pups were weaned. All pups were inoculated with two doses of 50 µg of IgY diluted in aluminium hydroxide/PBS on days 26 and 40 of life. Antibody levels were analysed by ELISA. Our results show an increase in levels of IgG1 and IgG2a anti-IgY in female offspring of mothers treated with ExTc compared to female offspring of untreated mothers. Furthermore, ExTc treatment suppressed the production of IgG2a anti-IgY antibodies in males. The data show that maternal exposure to ExTc can modulate the production of antibodies in the offspring.

The literature presents several instances of interaction between the nervous system (NS) and the immune system (IS). These interactions are promoted by several molecules, such as cytokines and hormones, with modulating action for both the NS and IS. In this sense, the two systems may influence each other: changes in behavior may be accompanied by alterations in the IS (e.g., immunosuppression) and immunological disorders, such as infections, may modulate behavior (e.g., anxiety and depression). Considering that chronic stress, in addition to affecting behavior, also modulates the IS and that there is evidence that moderate intensity physical exercise (PE) protects physical and mental health, the objective of this review is to explore the influence of moderate-intensity PE on behavior and immunity. Level of Evidence V; Expert opinion.
A literatura apresenta diversas instâncias de interação entre o sistema nervoso (SN) e o sistema imunológico (SI). Essas interações são promovidas por diversas moléculas, como citocinas e hormônios com ação moduladora tanto para o SN quanto o SI. Nesse sentido, os dois sistemas podem ter influência mútua: as alterações do comportamento podem ser acompanhadas por alterações do SI (por exemplo, imunossupressão), e distúrbios imunológicos como infecções, podem modular o comportamento (por exemplo, ansiedade e depressão). Considerando que o estresse crônico, além de afetar o comportamento, modula o SI e que há evidências de que o exercício físico (EF) de intensidade moderada ajuda a proteger a saúde física e mental, o objetivo da presente revisão é explorar a influência do EF de intensidade moderada sobre o comportamento e a imunidade. Nível de Evidência V; Opinião do especialista.

É comum tanto os praticantes recreacionais como atletas de alto rendimento realizarem atividades preparatórias antes de um exercício físico alvo, como uma forma de prevenir lesões. Contudo, o efeito do aquecimento na melhora do rendimento em atividades, que exijam força e potência, é questionável. O objetivo desse estudo foi analisar a influência de dois testes físicos para potência muscular, utilizados como atividades preparatórias, na melhora da potência do teste de salto horizontal. Foram avaliados 51 indivíduos, fisicamente ativos e não obesos com média de idade de 22,1 ± 3,0 anos, acadêmicos do curso de Educação Física da Universidade Estadual do Norte do Paraná UENP. Como forma de aquecimento foram utilizados os testes de salto vertical e o Sprint de 50 metros. A potência foi avaliada pelo teste de salto horizontal. Os dados foram analisados pelo pacote estatístico GraphPad Prism 5.0, com índice de significância de p<0,05. Os dados obtidos não apresentaram diferenças significativas entre os protocolos, demonstrando não haver influência na realização dos testes preparatórios com o desempenho na potência pelo salto horizontal. Conclui-se que a prática das atividades preparatórias propostas neste estudo não potencializou o aumento da potência muscular dos membros inferiores para realização do salto horizontal. (AU).
It is common for both recreational and high-performance athletes to perform preparatory activities prior to a targeted physical exercise as a way to prevent injury. However, the effects of warm-up on performance improvement in activities that require strength and power are questionable. The objective of this study was to analyze the influence of two physical tests for muscular power, used as preparatory activities, to improve power in the horizontal jump test. Fifty-one physically active and non-obese individuals with a mean age of 22.1 ± 3.0 years were evaluated, students of the Physical Education course at the State University of Northern Paraná - UENP. Vertical jump tests and 50 meter Sprints were used as a form of warm-up. Power was evaluated by the horizontal jump test. Data were analyzed using the statistical package GraphPad Prism 5.0, with a significance index of p <0.05. The data obtained did not present significant differences among the protocols, demonstrating that there was no influence of preparatory tests performance on power performance in the horizontal jump. It is concluded that the practice of the preparatory activities proposed in this study did not increase the muscular power of the lower limbs for the horizontal jump.

ABSTRACT
Estudos anteriores têm demonstrado os efeitos sobre o sistema imune e sobre os níveis de colesterol da dieta com fibra solúvel e proteína de soja em ratos. Nesse estudo, nós avaliamos os efeitos do farelo de aveia e da farinha de soja na resposta imune humoral de ratos Wistar tratados com dietas hipercolesterolêmicas. Os animais (6 grupos) foram alimentados com diferentes dietas por 6 semanas e inoculados duas vezes com antígeno (IgY). As amostras de plasma foram coletadas após cada inoculação e os níveis de anticorpos anti-IgY (IgM, IgG1 e IgG2a) foram avaliados por ELISA. Os animais que receberam 1% de colesterol apresentaram um aumento de IgG1 anti-IgY e uma redução de IgM e IgG2a anti-IgY em relação aos animais controle. Estes efeitos foram anulados em animais alimentados com 1% de colesterol e farelo de aveia ou aveia + proteína de soja, mas não em animais alimentados com 1% de colesterol e proteína de soja. As dietas contendo 1% de colesterol resultaram em lesões hepáticas e aumentaram o peso relativo do fígado e do baço, mas não afetaram o perfil lipídico, o ganho de peso e o consumo de alimentos ou eficiência na conversão alimentar. Em conclusão, uma dieta com alto teor de colesterol influencia na produção de classes de anticorpos em resposta a um antígeno de forma que pode ser revertida pelo farelo de aveia.
Previous studies have demonstrated the immunological and hypercholesterolaemic effects of soluble dietary fibre and soy protein in rats. In this study, we evaluated the effects of oat bran and soy flour on humoral immune response in Wistar rats fed hypercholesterolaemic diets. Animals (6 groups) fed with different diets for 6 wks were inoculated twice with antigen (IgY). Plasma samples were collected after each inoculation and anti-IgY antibody (IgM, IgG1 and IgG2a) levels were evaluated by ELISA. Animals receiving 1% cholesterol presented an increase in anti-IgY IgG1 and a reduction in anti-IgY IgM and IgG2a relative to control animals. These effects were abrogated in animals fed 1% cholesterol and oat bran or oat bran+soy protein, but not in animals fed 1% cholesterol and soy protein. Diets containing 1% cholesterol resulted in hepatic lesions and higher liver and spleen relative weights, but did not affect lipid profile, weight gain, food intake, or food conversion efficiency. In conclusion, a high-cholesterol diet influences classes of antibodies produced in response to an antigen in a way that can be reversed by oat bran
