Objective

The aim of this study is to investigate the role of 3T-MRI in assessing musculoskeletal health in children and young people.

Design

Bone, muscle and bone marrow imaging was performed in 161 healthy participants with a median age of 15.0 years (range, 8.0, 30.0).

Methods

Detailed assessment of bone microarchitecture (constructive interference in the steady state (CISS) sequence, voxel size 0.2 × 0.2 × 0.4 mm3), bone geometry (T1-weighted turbo spin echo (TSE) sequence, voxel size 0.4 × 0.4 × 2 mm3) and bone marrow (1H-MRS, point resolved spectroscopy sequence (PRESS) (single voxel size 20 × 20 × 20 mm3) size and muscle adiposity (Dixon, voxel size 1.1 × 1.1 × 2 mm3).

Results

There was an inverse association of apparent bone volume/total volume (appBV/TV) with age (r = −0.5, P < 0.0005). Cortical area, endosteal and periosteal circumferences and muscle cross-sectional area showed a positive association to age (r > 0.49, P < 0.0001). In those over 17 years of age, these parameters were also higher in males than females (P < 0.05). This sex difference was also evident for appBV/TV and bone marrow adiposity (BMA) in the older participants (P < 0.05). AppBV/TV showed a negative correlation with BMA (r = −0.22, P =  0.01) which also showed an association with muscle adiposity (r = 0.24, P = 0.04). Cortical geometric parameters were highly correlated with muscle area (r > 0.57, P < 0.01).

Conclusions

In addition to providing deep insight into the normal relationships between bone, fat and muscle in young people, these novel data emphasize the role of MRI as a non-invasive method for performing a comprehensive and integrated assessment of musculoskeletal health in the growing skeleton.
A Systematic Review About the Contribution of The Genus Tessaria (Asteraceae) To Cancer Study and Treatment
Authors: Sosa-Lochedino Arianna , Hapon María Belén , Gamarra-Luques Carlos
Published: June 2022

Belonging to the Asteraceae family, Tessaria (Ruiz & Pavon, 1753) is a genus of shrubs or small trees distributed in various habitats located from Argentina to the southwestern United States of America. The taxa are composed of five confirmed species, which have been previously reported for their ethnopharmacological uses as hypocholesterolemiant, hypoglycemic, antitussive, anti-inflammatory, anticancer, and abortifacient agent; it also has been used in hepatic, renal, pulmonary, and rheumatic diseases. Up to the present, T. absinthioides, T. ambigua, T. dodoneifolia, T. fastigiata and T. integrifolia have been chemically analyzed. While decoctions, infusions, methanolic, and hydromethanolic extracts are the most studied botanical compounds, its most recognized phytochemical constituents are caffeoylquinic acid, eupatorin, naringenin, protocatechuic, and quercetin. Scientifically, several biomedical properties such as virucidal, antibacterial, leishmanicidal, insecticidal, gastroprotective, antiasthmatic, hypoglycemic, and antiatherogenic were attributed to the genus. Concerning oncologic research, the chemicals produced by Tessaria have antitumor activities interfering with carcinogenesis, cell proliferation, metastasis, and angiogenesis. In addition, the natural extracts obtained from Tessaria species have biological activities closely related to cancer, acting as antioxidants and anti-inflammatories. In particular, it has been reported that T. absinthioides resulted cytotoxic against several cancer cell lines and acts as an antitumoral compound in murine models. Due to the aforementioned antecedents, the Tessaria species are considered undervalued within the oncological field; the goal of the current systematic review is to summarize the information available on the genus, relevant for cancer research and treatment.

OBJECTIVES

Although vestibular deficits are more prevalent in hearing-impaired children and can affect their development on many levels, a pediatric vestibular assessment is still uncommon in clinical practice. Since early detection may allow for timely intervention, this pioneer project has implemented a basic vestibular screening test for each six-month-old hearing-impaired infant in Flanders, Belgium. This study aims to report the vestibular screening results over a period of three years and to define the most important risk factors for abnormal vestibular screening results.

METHODS

Cervical Vestibular Evoked Myogenic Potentials with bone-conduction were used as a vestibular screening tool in all reference centers affiliated to the Universal Newborn Hearing Screening Program in Flanders. From June 2018 until June 2021, 254 infants (mean age: 7.4 months, standard deviation: 2.4 months) with sensorineural hearing loss were included.

RESULTS

Overall, abnormal vestibular screening results were found in 13.8% (35 of 254) of the infants. The most important group at risk for abnormal vestibular screening results were infants with unilateral or bilateral severe to profound sensorineural hearing loss (20.8%, 32 of 154) (P < .001, odds ratio = 9.16). Moreover, abnormal vestibular screening results were more prevalent in infants with hearing loss caused by meningitis (66.7%, 2 of 3), syndromes (28.6%, 8 of 28), congenital cytomegalovirus infection (20.0%, 8 of 40), and cochleovestibular anomalies (19.2%, 5 of 26).

CONCLUSIONS

The vestibular screening results in infants with sensorineural hearing loss indicate the highest risk for vestibular deficits in severe to profound hearing loss, and certain underlying etiologies of hearing loss, such as meningitis, syndromes, congenital cytomegalovirus, and cochleovestibular anomalies.

Published: June 2022

The conducted analysis allows us to make an assumption about the onomatopoeic origin of the Polish ornithonym łastówka - jaskóła, as well as the dominance of vocal features in the etymology of Polish ornithonyms in general. In this regard, the theory of onomatopoeia receives its new development and is seen as one of the directions for future research in this area.
Muscle fatique and muscle damage in strength training
Authors: Böge Veysel , Patlar Süleyman
Published: June 2022

Background and Study Aim. The aim of this study is to investigate the effects of different types of contractions on muscle damage and muscle fatigue in sedentary individuals.

Material and Methods. Thirty healthy male sedentary individuals participated in the study. Strength training in different types of contractions applied in the study was applied 3 times a week for 8 weeks. Before the study, the training loads were determined by making maximal force measurements of all subjects. The 30 subjects participating in the study were divided into 3 groups: isometric (n = 10), concentric (n = 10) and eccentric (n = 10) contraction group. Appropriate amount of blood samples was taken from the elbow vein 2 times from all subjects, before the studies and at the end of the 8-week strength training.

Results. It was observed that eight-week strength training did not cause muscle fatigue in all groups and did not create a statistically significant difference (P> 0.05). Strength training with isometric and concentric contractions for eight weeks significantly increased serum lactate dehydrogenase (LDH), C-reactive protein (CRP), myoglobin (Mb), interleukin 6 (IL-6) levels, while concentric strength training significantly reduced serum aspartate amino transferase (AST) levels. Strength training with eccentric contractions significantly increased serum LDH, CRP, AST, Mb and IL-6 levels, while significantly reducing serum tumor necrosis factor alpha (TNF-α) levels. Strength training with eccentric contractions significantly increased serum creatine kinase (CK), CRP, AST, IL-6 and Mb levels compared to strength training with isometric and concentric contractions at the end of the eight-week study period, but did not show the same significant effect in other parameters.

Conclusions. As a result, it can be said that eccentric strength training performed in sedentary individuals leads to more muscle damage than isometric and concentric strength training.
Effects of high intensity interval training on trace minerals and physiological parameters in tennis players
Authors: Öner Salih , Yasul Yavuz
Published: June 2022

Background and Study Aim. This study investigated the effects of HIIT (high-intensity interval training) implementations on some serum elements, resting heart rate, total body weight, and BMI parameters in tennis players.

Material and Methods. The study group consisted of 20 athletes (aged 18-22) who were actively playing tennis. The athletes were divided into experimental (n=10) and control (n=10) group. To assign participants to these groups homogeneously, preliminary measurements were made before the study, and the results were used for clustering analysis. While the control group continued their regular tennis training, the experimental group was given additional HIIT three days a week besides regular tennis training. Measurements of BMI, resting heart rate, and body weight were taken, and serum samples were collected before and after training from both groups. The SPSS package program was used in data analysis. The level of significance was set at p<0.05 in the tests. Participants showed significant differences in sodium, calcium, iron, resting heart rate, weight, and BMI parameters between groups (p<0.05).

Results. However, no significant differences between the groups were found in potassium, chlorine, and magnesium parameters (p>0.05). The within-group measurements of sodium, calcium, resting heart rate, weight and BMI levels decreased in the experimental group in the post-test, while iron levels were higher in the post-test compared to the pre-test value (p<0.05). On the other hand, the pre-test and post-test values were similar within the control group, and there were no significant differences (p>0.05).

Conclusions. Training remodelled with HIIT implementation can affect athletes' element levels, BMI, total body weight, and resting heart rate. In addition, the increase in iron levels due to HIIT in the experimental group was important. We believe that this may affect both muscle contraction functions and the efficiency performance output. Lastly, due to the decrease of calcium and sodium elements with HIIT implementations, we suggest that HIIT applications should not be performed unsupervised. In addition, by tracking the element levels of athletes, they should be supported with supplements or nutritional meals in line with expert advice when necessary.

Published: June 2022

Background and Study Aim. Chin-up is an exercise that is done to improve the strength, muscular endurance and size of the upper back and arm muscles. There are many ways to perform chin-up exercises including by performing it with different forms of knee flexion. This study aims to examine the effects of knee flexion on muscle activation and performance during chin-up exercise.

Material and Methods. A total of twenty-one healthy trained male (age 20-25 years old) were recruited and were instructed to perform chin-up exercises in three knee conditions: i) knee fully flexed, ii) partial knee flexed, and iii) straight knee. Chin-up performance was measured by the number of repetitions performed in three sets. Muscle activation was measured using EMG and taken from latissimus dorsi (LD), posterior deltoid (PD), and biceps brachii (BB) during both concentric and eccentric phase. One-way repeated measure Analysis of Variances (ANOVA) were conducted to compare the muscle activation and number of repetitions performed across the three variation of chin-up exercise.

Results. Findings showed that during the concentric phase, BB recorded higher muscle activation during straight knee compared to knee fully flexed and partial knee flexed, p < .05. In addition, chin-up performance during straight knee and partial knee flexed were better than knee fully flexed, p < .05.

Conclusions. The results of this study demonstrated the importance to consider techniques manipulation during exercises due to its effects on acute responses as shown by number of repetitions and muscle activation in this study that might also affect the long-term outcomes.
The negative effects of the pandemic on human behavior; alienation and social anhedonia: the example of sport sciences students
Authors: Akgül Mehmet H. , Tekin Nedim
Published: June 2022

Background and Study Aim. The social change brought about by the pandemic process all over the world has led to the restructuring of human behavior and daily life practices. This process has brought with it some social-psychological problems (such as alienation and social anhedonia) for social segments. For this reason, the aim of the research is to examine the alienation and social anhedonia levels of the students studying at the faculty of sport sciences during the pandemic process.

Material and Methods. The sample of the research consists of students studying at the faculties of sport sciences of different universities in Turkey. A total of 423 students (271 males, 152 females) participated in the study. Due to the normal distribution of the data, the t-test, one of the parametric tests, was performed for paired groups, and the relationship between Social Anhedonia Scale and Alienation Scale sub-dimensions was tested with Pearson correlation analysis. Statistical analyzes were performed with the “Statistical Package for the Social Sciences” commercial software (SPSS for Windows, version 26.0, SPSS). The significance level was determined as p<0.05 in the analyzes, and skewness and kurtosis values were considered for the normality analysis.

Results. According to the results obtained, it can be said that the pandemic process negatively affected the social anhedonia and alienation levels of male students studying at the faculty of sport sciences compared to female students. Again, it is seen that the level of alienation of the students who do sports at the professional level is higher than the students who do sports at the amateur level. Similarly, it is seen that the students of the faculty of sport sciences dealing with team sports have higher levels of social isolation, which is one of the sub-dimensions of the alienation scale, compared to the students who are engaged in individual sports. Finally, there is a negative and low-level significant relationship between social anhedonia and alienation scale sub-dimensions (p<0.05; r=-0.187; r=-0.164; r=-132).

Conclusions. As a result, it can be said that the pandemic process has had similar negative effects on the students studying in the faculties of sport sciences, as in other social segments.

Published: June 2022

Background and Study Aim. To assess the effects of Anulom Vilom Pranayama (AVP) or alternative nostril breathing and Rope Mallakhamb Training (RMT) on respiratory parameters among university females with athletic backgrounds.

Material and Methods. A quasi experimental study was performed on thirty-six, university female students from the Department of Physical Education (T), Guru Nanak Dev University, Amritsar, Punjab, India. The subjects were divided in three groups. The groups were subjected to 4-weeks of intervention including: Group A (n1=12) subjected to AVP, Group B (n2=12) subjected to RMT, and Group C: (n3=12) no training or control. Respiratory parameters were measured twice, pre and post intervention using a wet spirometer. All measurements were performed three times and the average values were recorded for analysis.

Results. 4-weeks of AVP resulted in positive increases for respiratory parameters measured including Tidal Volume (VT) 25.7%, Inspiratory Reserve Volume (IRV) 29.4%, Expiratory Reserve Volume (ERV) 27.1%, Vital Capacity (VC) 33.2%, and Inspiratory Capacity (IC) 31.6% compared to the control group. Also, 4-weeks of RMT had a positive impact on respiratory parameters including (VT) 19.8%, (IRV) 22%, (ERV) 19.4%, (VC) 32 % and (IC) 28.1% compared to the control group.

Conclusions. Both AVP and RMT had a positive impact on respiratory parameters. Also, AVP training has a more positive impact on respiratory parameters than RMT and may also contribute to the enhancement of concentration-based performance and voluntary control of breathing among young females from athletic backgrounds. As a result, AVP training can be more beneficial for a competitive edge in order to improve the athletes' primary need for respiratory endurance.

Authors: Hwang Inseon , Kwon Hoonjeong
Published: June 2022

Acrylamide formation in carbohydrate-rich botanical powders consumed in Korea was investigated in this study. Free asparagine and monosaccharide contents were measured as the chief precursors to acrylamide formation. The highest levels of acrylamide were detected in heated lotus roots, followed by potatoes, Jerusalem artichokes, and yams. Tubers and rhizomes contained more asparagine than sugar and had a high ratio of free asparagine to free amino acids. Acrylamide was formed preferably when sugars were the limiting factor, rather than when the same amount of asparagine was limited. This study demonstrated the potential for several botanical powders in the Korean diet to be contaminated by acrylamide.

Published: June 2022

RESUMO Introdução: tumores hepáticos são neoplasias raras na infância (1-2%), sendo que cerca de 2/3 são malignos. O hepatoblastoma (HB) é o mais frequente, seguido do carcinoma hepatocelular (CHC). Em ambos, o principal tratamento é a ressecção cirúrgica completa. Atualmente, a quimioterapia e o transplante hepático têm melhorado os resultados. Objetivo: estudo do perfil epidemiológico e evolução dos casos de cânceres hepáticos em um hospital pediátrico de referência. Método: Levantamento retrospectivo de prontuários de pacientes até 18 anos com diagnóstico de neoplasia maligna primária hepática entre 2012 e 2020 realizado no maior hospital exclusivamente pediátrico do Brasil. Resultados: foram atendidos 13 pacientes com tumores malignos hepáticos (HB 12, CHC 1). Dos casos de HB, 66,7% eram do sexo masculino, com idade média de 2 anos e a principal alteração foi massa abdominal palpável. Os tumores envolviam em média 3 segmentos hepáticos, mais em lobo direito (54%). Um paciente foi tratado com cirurgia sem neoadjuvância, um foi submetido a transplante inicialmente e outros 2 necessitaram de transplante hepático como resgate. O tempo de seguimento dos pacientes com HB foi de 39 meses e apenas 1 caso foi a óbito por neutropenia febril. A sobrevida geral e livre de doença em 5 anos foi de 91,7% e 81,5% respectivamente. Conclusão: o estadiamento avançado no momento do diagnóstico sempre foi um fator de mau prognóstico em pacientes com tumores hepáticos malignos primários. Entretanto, os resultados e a sobrevida têm melhorado significativamente com o avanço da quimioterapia, da técnica cirúrgica e do transplante hepático.

Published: June 2022

ABSTRACT Introduction: liver tumors are rare neoplasms in childhood (1-2%), and about 2/3 are malignant. Hepatoblastoma (HB) is the most frequent, followed by hepatocellular carcinoma (HCC). In both, the main treatment is surgical resection. Currently, chemotherapy and liver transplantation have improved outcomes. Objective: study of the epidemiological profile and evolution of liver cancer cases in a referral pediatric hospital. Methodology: a retrospective survey of medical records of patients aged up to 18 years with a diagnosis of primary malignant hepatic neoplasm between 2012 and 2020, carried out in the largest exclusively pediatric hospital in Brazil. Results: a total of 13 patients with malignant liver tumors (HB 12, HCC 1) were treated. Of the HB cases, 66,7% were male, with a mean age of 2 years and the main alteration in the palpable abdominal mass. Tumors involved an average of 3 liver segments, more in the right lobe (54%). Only one patient was treated with surgery without neoadjuvant therapy, another one underwent transplantation like the first treatment, and another 2 required liver transplantation as a rescue. The middle follow-up time of patients with HB was 39 months and only 1 case died due to febrile neutropenia. The 5-year overall and disease-free survival was 91.7% and 81.5%, respectively. Conclusion: Advanced staging at the time of diagnosis has always been a poor prognostic factor in patients with primary malignant liver tumors. However, the results and survival have improved with the advancement of chemotherapy, surgical technique, and liver transplantation.

Published: June 2022

RESUMO O plano econômico do governo brasileiro denominado “Real” afetou o mercado de trabalho dos setores comercializáveis e não comercializáveis de diferentes maneiras. A política cambial e o processo orientado para o livre mercado adotado provocaram mudanças nos preços relativos em favor do setor não comercializável. Este artigo mostra o aumento da força de trabalho neste setor e uma redução da diferença entre a renda do setor comercializável e não comercializável. Além disso, mostra a melhoria dos indicadores de pobreza da força de trabalho, especialmente aqueles relacionados ao setor informal. Este artigo é baseado em dados do PME-IBGE (região metropolitana de São Paulo, 1994, 1995 e 1996).

Ajustamento estrutural e crescimento agrícola na década de 80: notas adicionais
Authors: FERREIRA FILHO JOAQUIM BENTO DE SOUZA
Published: June 2022

RESUMO Este artigo trata de alguns aspectos do desenvolvimento da agricultura brasileira no passado próximo. O diferencial da taxa de crescimento entre agricultura e indústria nos anos 80 foi analisado pela primeira vez. A conclusão é que o tipo de ajuste estrutural que a economia brasileira enfrentou naquele momento favoreceu a agricultura a crescer mais rapidamente do que o setor industrial. A queda na renda nacional causada pela interrupção da poupança externa afetou principalmente os investimentos, constituídos integralmente por produtos industriais. Dessa maneira, o crescimento industrial foi muito mais afetado do que a agricultura. Mas isso não seria suficiente para explicar o crescimento real da agricultura na época. Assim, verificou-se que havia também um importante estímulo do lado da oferta à agricultura, devido a uma enorme redução nos custos de produção agrícola. Esse certamente foi um fator importante relacionado ao crescimento da agricultura nos anos 80.

RESUMO A resina furfurílica (RF) é uma bioresina obtida a partir do álcool furfurílico (AF), extraído de fontes renováveis. Essa resina quando curada apresenta excelentes características, como elevada dureza, estabilidade química e boa resistência mecânica, que viabilizam sua utilização em diferentes áreas, destacando-se os setores aeroespacial e de bioengenharia. No entanto, a sua utilização em larga escala ainda é limitada, devido ao difícil controle do seu processo de síntese, pois a reação de policondensação do AF é extremamente exotérmica. O presente trabalho visa contribuir com a área de síntese da RF, por meio do estudo de sua obtenção em meio ácido e em baixa temperatura (∼50 ºC), variando os tempos de reação (1, 2 e 3 h), visando um maior controle da exotermia do meio reacional. O sucesso das sínteses realizadas foi comprovado por análises de espectroscopia na região do infravermelho com transformada de Fourier, que evidenciaram a presença de cetonas e estruturas de acordo com Diels-Alder e de Dunlop e Peters. Medidas de viscosidade apresentaram baixos valores (230 a 470 mPa.s), os quais são concordantes com as baixas massas molares obtidas por cromatografia de permeação em gel ( M ¯ w: ∼800 g/mol). Esses resultados mostram que as condições de síntese utilizadas desfavoreceram cineticamente o avanço da reação; porém, não promoveram picos exotérmicos. As análises termogravimétricas (TGA) das RFs curadas com ácido p-toluenosulfônico (2 e 3%, m/m) mostraram perdas de massa desde o início da análise, devido à presença de água e de frações de baixa massa molar na amostra. Esses resultados são concordantes com as imagens obtidas por microscopia eletrônica de varredura, que mostraram um elevado volume de poros. Resultados relevantes foram observados nas análises de TGA sob atmosfera inerte, com valores elevados de carbono fixo (50–60%), indicando o potencial uso das RFs sintetizadas na área de materiais carbonosos.

Abstract Satellites associated begomoviruses are the most diverse group of plant viruses in tropical and subtropical regions. In Pakistan, during field surveys in 2019-2020, Sonchus palustris (a weed plant) was observed showing begomovirus symptoms i.e., vein yellowing and mosaic patterns on leaves. Rolling circle amplification from total isolated DNA of symptomatic leaves was performed to amplify circular viral genomes. Subsequent cloning and sequencing showed that a new strain of Alternanthera yellow vein virus (AlYVV) is associated with vein yellowing disease of S. palustris. The identity percentage analysis through BLAST search and SDT analysis showed that the new strain is 94-98% identical to AlYVV isolates reported from Pakistan, India and China. In phylogenetic tree, it clustered with AlYVV-[PK:E prostrata:15-KX710155], AlYVV-[PK:E prostrata:13]-KX906697] and AlYVV-[PK:E prostrata:11]-KX906694] previously reported from Pakistan. There was no detectable level of betasatellite or any other satellite molecule in the samples studied here. Phylogenetic analysis of Rep and CP genes of AlYVV with corresponding genes of closely related viruses circulating in Southeast Asia showed intra-specific recombination involving both complementary and virion sense region of virus. Relaxed clock and Bayesian Skyline Plot analysis based on CP gene sequences indicated slight higher substitution rates (4.75 x 10-3 substitutions/nucleotide/year). In the Indian subcontinent satellite-associated monopartite begomoviruses predominately infect crops and non-crop plants. But AlYVV is found infecting mostly non-crop plants independent of satellite molecules. We hypothesize here that AlYVV evolved as a true monopartite begomovirus in the Indian sub-continent and could be a great threat to introduced crops under suitable conditions. Such studies are crucial to understand probable future epidemics of begomoviruses in the region.

Abstract This study aims to record clinical and epidemiological data on COVID-19 in the local town of São Caetano de Odivelas (PA), in order to propose guidelines for the control of the pandemic and to reverse the socio-economic impacts. A form elaborated in the Google Docs application was used, by 200 respondents, followed by analysis and interpretation based on discourse and socio-cultural characteristics, revealing the ideology of political groups that hinder public policies, as well as the absence of socio-anthropological aspects in the consideration of sanitary measures. To conclude, three lines of action are proposed: awareness and clarification for the public concerning the pandemic, configuration of contagion networks based on families, and the guarantee of income and provisions for workers.
Covid-19 and disaster capitalism: “Passando a boiada” in the Brazilian meat processing chain
Authors: Sordi Caetano , Segata Jean , Lewgoy Bernardo
Published: June 2022

Abstract The article discusses the social impacts of the COVID-19 pandemic on the meat processing industry in southern Brazil. Based on the notion of disaster capitalism, we examine how political and corporate agents have taken advantage of the health catastrophe to create a privileged space for simplifications and deregulation in this sector. According to our reasoning, they accelerate precarious work in the meat industry and amplify the harmful effects of agribusiness on local ecologies and global ecosystems. In light of this, we also emphasize the analytical potential that results from the intersection between the categories of syndemics and structural violence to displace the traditional analyses of risk groups and behaviors in highlighting environments and their agents.
Pour d’autres politiques de la vie: Expériences de personnes âgées pendant la pandémie de Covid-19
Authors: Rifiotis Fernanda Cruz
Published: June 2022

Résumé Dans cet article, nous analyserons les expériences de personnes âgées face à la pandémie de Covid-19, afin de comprendre comment les sens attribués à cet évènement multiple et inégal fournissent des éléments pour réfléchir à « d’autres politiques de la vie ». Cette réflexion se fonde sur le matériel ethnographique né de la recherche anthropologique collective au sujet des impacts de la pandémie de Covid-19 sur les personnes âgées. Concrètement, dans l’article, nous analysons les récits de trois personnes âgées, deux femmes et un homme, qui permettent de problématiser les discours concernant la « minorité des personnes âgées », de même que d’inscrire ces sujets comme « groupe à risque ». En outre, ces récits révèlent un isolement social incitateur de multiples agencements et de la construction/renforcement de réseaux d’interdépendance et d’aide. Si la pandémie a été associée à la tristesse, la solitude, le deuil et la perte de temps de vie, le matériel ethnographique permet de rendre visible d’autres sens, tels que la réflexivité, la revendication, la résignation/attente et les apprentissages.

Published: June 2022

Abstract This text presents initial questions from the SEXVID national survey on sexual practices and risk management in the Covid-19 context. The category of risk management, taken from studies about management and health in relation to HIV/AIDS and practices of assemblage, with reference to studies of materialities, articulates heterogeneous elements involved in managing offline sexual encounters in the context of the pandemic. We focus on two questions: how does this management take place, especially in a political environment lacking public policies on prevention and risk, and what are the practical materialities that constitute this articulated assemblage of elements that justify or not the risk of contamination. We use scenes constructed from semi-structured interviews in the initial phase of the study to contextualize the central question and learn about the impact of the pandemic on the sexual experiences of part of the population.

ABSTRACT Objective: to develop and validate a mobile application for the guidance of family members of children and adolescents undergoing treatment with oral antineoplastic drugs. Method: this is methodological research developed in seven steps: search for themes through interviews with twenty-three family members of children and adolescents undergoing oral chemotherapy; theoretical study; mobile application development; validation with thirteen expert judges; adequacy; validation with twelve family members of children and adolescents undergoing oral chemotherapy and mobile application final adaptation. The interviews were analyzed using the Interface de R pour Analyses Multidimensionnelles de Textes et de Questionneires software and validated with a Likert-type scale, considering validated items with a Concordance Index equal to or greater than 70%. Results: the application “Quimio em Casa” was returned with two interfaces, a desktop version aimed at health professionals and the application for family members of children and adolescents undergoing treatment with oral chemotherapy. The contents that guided the application development were storage, handling, administration, specific care for each chemotherapy agent, adverse effects, when to go to the emergency room and daily checking of administrations. The application was designed and validated with an adequacy Concordance Index of 96.7% among judges, and 100% by family members. Conclusion: the application proved to be valid as an educational technology in practical application with family members of children and adolescents undergoing oral chemotherapy.

Abstract The Serranias Costeiras of the Ribeira de Iguape River basin comprise landscapes with steep slopes, where many streams are contained in protected areas. We evaluated the importance of these protected areas for stream fish diversity. We sampled the ichthyofauna during the dry season of 2010, 2018 and 2019 in 36 stream stretches. We used beta diversity measures and estimated species richness and dark diversity in streams from two types of protected areas (full protection, FP and sustainable use, SU) and outside (Out). The altitude-width and velocity gradient of the streams explained the species turnover. The PA type promoted the richness difference, with FP streams having less species richness than SU and outside. Streams from FP presented lower species richness and dark diversity. These results indicate that the few species in FPs are well protected. The FP streams contain a relevant proportion of the regional species pool and, therefore, are essential for conserving fish stream diversity in the study region. On the other hand, streams from SU or Out have higher species richness, but their fish fauna is more vulnerable. Due to longitudinal stream connectivity, we highlight the importance of rethinking the limits of protected areas.

Abstract Introduction: Chronic kidney disease, more prevalent in the elderly, is considered a public health issue worldwide. Objective: To evaluate the impact of automated, peritoneal dialysis modalities, intermittent and continuous, on the inflammatory profile of elderly people with chronic kidney disease. Methods: Prospective, cross-sectional and analytical study carried out in a dialysis clinic in Brasília - Brazil, with 74 elderly people aged 60 years or older. The patients underwent rapid Peritoneal Equilibration Test, clinical assessment, blood collection for biochemical and cytokine assessments, interleukin 6 and transforming growth factor beta 1, and answered a quality-of-life questionnaire (KDQOL-SF36). We used a 5% significance level for data analysis, associations and correlations. Results: Patients in the continuous modality had higher serum values of transforming growth factor beta 1 than those in the intermittent modality, which had higher peritoneal transforming growth factor beta 1, age and residual renal function than those in continuous mode. Interleukin 6 dosage in the peritoneum was associated with age, while serum IL-6 was associated with IL-6 in the peritoneum, time on dialysis and age. There was no association between the modality and the presence of diabetes, blood volume or nutritional status. Both modalities enable good adaptation to the dialysis treatment. Conclusion: Inflammation in automated peritoneal dialysis is mainly associated with low residual renal function, advanced age and longer time on therapy, and not to the type of dialysis performed.

Abstract Introduction: With aging, it is common for some changes to occur in different areas of cognition, such as memory, executive function, language and psychomotor speed. However, regular physical activity has been described as an excellent way to alleviate the degeneration caused by aging within the various physical, psychological and social domains. Objective: To evaluate the effects of resistance training in elderly women with mild cognitive impairment. Methods: Experimental study with 31 sedentary elderly women divided into control (CG; n=15) and resistance training (RTG; n=16) groups who underwent assessment of anthropometric measures, body composition, maximum strength, heart rate and blood pressure and questionnaire application (Mini-Mental State Examination). Results: Cognitive ability increased in RTG (post 26.00 ± 2.13 vs. CG 22.24 ± 3.82 vs. pre 24.06 ± 2.38 RTG). In RTG, there was a reduction in systolic blood pressure (post 107.50 ± 11.97 vs. CG 126.00 ± 9.72 vs. pre 124.13 ± 12.55 mmHg RTG), diastolic blood pressure (post 68.50 ± 8.15 vs. CG 81.73 ± 4.59 vs. pre 74.69 ± 6.87 mmHg RTG) and double product (post 7746 ± 1244 vs. CG 9336 ± 1595 vs. pre 9286 ± 1309 mmHg x bpm RTG), but not in heart rate (post 72.00 ± 7.40 vs. CG 74.00 ± 10.50 vs. pre 74.94 ± 8.42 bpm RTG). Regarding muscle strength, an increase was evident in all exercises. Conclusion: The present study showed that resistance training in elderly women increased muscle strength and reduced hemodynamic variables. But the most important finding was that there was an increase in cognitive capacity.
La madre (negra de la) patria. Raza, género y nación en una fiesta tradicional
Authors: Brena Valentina
Published: June 2022

Resumen La Fiesta de la Patria Gaucha es un evento tradicional celebrado anualmente en Tacuarembó, Uruguay. En octubre del 2018, el lanzamiento del afiche que convocaba a su 33ª edición, desató una polémica a partir de una imagen producida para la ocasión en la que una mujer afro amamantaba a un bebé blanco situada en la época colonial o post-colonial. El debate adquirió dimensión nacional y fue tema central en los medios masivos de comunicación; se desencadenó en múltiples direcciones e incluyó a una multiplicidad de actores, a saber: referentes de organizaciones sociales afrodescendientes, autoridades del primer y segundo nivel de gobierno, representantes de partidos políticos, además de los sujetos vinculados a la autoría de la obra. Del complejo entramado de interpretaciones enfrentadas en torno a la in-existencia de una imagen racista, es que realizo un análisis de las relaciones raciales y de género en las lecturas de la nación.
