ABSTRACT The breathing pattern of Mouth Breathing (MB) implies the adaptation of body posture to facilitate the passage of airflow through the oral cavity, which can be prevented or reversed through physical exercise. However, there is no consensus on which is the best model of exercise program to minimise these postural adaptations. The purpose of the review was to investigate the effect of different physical exercise programs on the posture of mouth-breathing children and adolescents. The research was performed in Scopus, PubMed, Lilacs, Bireme, and Scielo databases in November 2022. The following descriptors were included: “mouth breather and exercise”, “mouth breathing and exercise”, “nasal obstruction and exercise”, “mouth breather and exercises”, “mouth breathing and exercises”, and “nasal obstruction and exercises”. Clinical trials related to the effect of physical exercise on the posture of MB children and adolescents were considered. Among 2796 identified studies, six were included. The mean score of the methodological quality scale of the selected studies was 5.5 points on a scale of 0 to 10. All studies showed an improvement in body posture after the exercise program. The exercise programs comprised muscle strengthening and stretching exercises, neuromuscular proprioceptive facilitation, and postural and diaphragmatic reeducation. The duration of the programs and the weekly frequency varied in the studies. Although it is difficult to compare studies and establish guidelines for formulating an exercise protocol, it was observed that upper limb strengthening and stretching exercises could effectively improve the body posture of MB children and adolescents.

RESUMO No semiárido do Nordeste brasileiro as condições edafoclimáticas podem favorecer riscos de salinização do solo, principalmente quando se utiliza água de má qualidade para irrigação. Nesse contexto, técnicas que possibilitem melhorias nos rendimentos da cultura do melão em condições adversas, como a salinidade, são, portanto, de grande relevância para o setor produtivo. Logo, o objetivo deste estudo foi avaliar a eficácia do peróxido de hidrogênio (H2O2) na aclimatação do meloeiro submetido a diferentes níveis salinos na água de irrigação. Os tratamentos consistiram de duas condutividades elétricas da água de irrigação (0,3 e 5,0 dS m-1) e quatro concentrações de H2O2 (0, 5, 10 e 15 µmol L-1). O delineamento experimental utilizado foi o de blocos casualizados, em esquema fatorial 2 × 4, com quatro repetições e quatro plantas por parcela. O aumento da salinidade da água de irrigação reduz o crescimento, as trocas gasosas e a produção do meloeiro. No entanto, o H2O2, na concentração de 6,35 µmol L-1 proporcionou melhorias na fisiologia, crescimento e produção, além de reduzir os efeitos deletérios do estresse salino na produção de melão.

ABSTRACT In the semi-arid region of northeastern Brazil, soil and climate conditions can increase the risk of soil salinization, particularly when poor-quality water is used for irrigation. Therefore, techniques that improve the yields of melon culture under adverse conditions, such as salinity, are of great relevance to the production sector. The objective of this study was to evaluate the effectiveness of hydrogen peroxide (H2O2) in acclimatizing melon trees subjected to irrigation water with different salinity levels. The treatments consisted of irrigation water with two electrical conductivities (0.3 and 5.0 dS m-1) and four concentrations of H2O2 (0, 5, 10, and 15 µmol L-1). The experimental design used was randomized blocks, arranged in a 2 × 4 factorial scheme, with four replicates and four plants per plot. Increase in salinity of irrigation water reduced the growth, gas exchange, and production of melon plants. However, H2O2, at a concentration of 6.35 µmol L-1, yielded improvements in physiology, growth, and production, in addition to reducing the deleterious effects of saline stress on melon production.

Abstract The hospital pharmacy needs a constant process of evaluation and monitoring of its activities. In Brazil, several agencies establish tasks and duties for pharmacists, but little is known about the compliance and the perception of the professional regarding these policies. The present study aims to characterize the pharmacist’s perception of Brazilian hospital pharmacy policies according to the Basel Statements. A search was performed for the contacts of all medium and high complexity hospitals in the country. Subsequently, a questionnaire elaborated following the Basel Statements was sent by e-mail to hospital pharmacists throughout the country. The domain analyzed was "Human Resources, Training, and Development". Statistical analyses were performed using SPSS 19.0. Pharmacists representing a total of 111 hospitals from all Brazilian regions answered the survey questionnaire and showed that more than half of the hospital pharmacists perceive themselves as not complying, whether in the service of local, national, or pharmaceutical education. Besides updating the professionals in relation to national policies, it is necessary that the representative bodies of the pharmaceutical class be more present in the elaboration and evaluation of the policies directed to human resources, seeking uniformity and the possibility of carrying out the activities required.

RESUMO Objetivou-se avaliar a substituição de um antibiótico promotor de crescimento por óleos essenciais de erva-doce (Foeniculum vulgare) e citronela (Cymbopogon winterianus) na dieta de codornas sobre o desempenho, rendimento de carcaça e cortes. Para isso, foram utilizadas 240 codornas europeias machos e fêmeas de um dia de idade distribuídos em delineamento inteiramente ao acaso com quatro tratamentos, cinco repetições e 12 animais por unidade experimental. Os tratamentos consistiram em: CP- Dieta sem os óleos essenciais de erva-doce ou citronela e com o promotor de crescimento (bacitracina de zinco); CN- Dieta sem os óleos essenciais e sem o promotor de crescimento; OC- Dieta com + 0,078% de óleo essencial de citronela sem o promotor de crescimento; OED- Dieta com + 0,078% de óleo essencial de erva-doce sem o promotor de crescimento. O experimento teve duração de 42 dias, no qual as variáveis de desempenho foram analisadas em três períodos (1-14 dias; 14-21 dias e 22-42 dias) e o rendimento de carcaça e cortes em dois períodos (aos 21 e 42 dias). Os dados observados foram submetidos à análise de variância e a comparação das médias foi realizada pelo teste de Tukey a 5%. A presença dos óleos essenciais influenciou positivamente (P<0,05) as variáveis de desempenho e o rendimento de carcaça e cortes em todos os períodos analisados. A utilização de óleos essenciais de erva-doce e citronela em substituição a bacitracina de zinco na dieta de codornas europeias melhora o desempenho e o rendimento de carcaça e cortes.

ABSTRACT The objective of this study was to evaluate the replacement of a growth-promoting antibiotic by fennel (Foeniculum vulgare) and citronella (Cymbopogon winterianus) essential oils in the quail diet on performance variables (weight gain, feed intake, feed conversion), as well as the carcass and cut yield. To do so, 240 one-day-old male and female European quails were distributed in a completely randomized design with four treatments, five replications and 12 animals per experimental unit. The treatments consisted of: PC – positive control diet without fennel or citronella essential oils and with the growth promoter (zinc bacitracin); NC – negative control diet without essential oils and without growth promoter; CEO - Diet with +0.078% citronella essential oil without the growth promoter; and FEO - Diet with +0.078% fennel essential oil without the growth promoter. The experiment lasted 42 days, in which the performance variables were analyzed in three periods (1-14 days; 14-21 days; and 22-42 days) and the carcass and cut yield in two periods (at 21 and 42 days). The observed data were submitted to analysis of variance and the comparison of means was performed using the Tukey’s test at 5% significance. The presence of essential oils positively influenced (P<0.05) the performance variables and the carcass and cuts yield in all analyzed periods. The use of fennel and citronella essential oils to replace zinc bacitracin in the diet of European quails improves performance and the carcass and cut yield.

RESUMO A doença renal crônica (DRC) tornou-se um peso na saúde pública em todo o mundo por sua crescente incidência e prevalência, seu alto impacto na qualidade de vida relacionada à saúde (QVRS) e na expectativa de vida, e alto custo pessoal e social. Pacientes com DRC avançada, em diálise ou não, sofrem de uma carga de sintomas muito semelhantes aos de outras doenças crônicas, e têm uma sobrevida não superior àquela de muitas doenças malignas. Assim, nos últimos anos, recomenda-se que os cuidados paliativos renais sejam integrados aos cuidados tradicionais prestados a essa população. Este trabalho fornece uma visão geral atualizada sobre os cuidados paliativos renais discutidos na literatura relevante.

ABSTRACT Chronic kidney disease (CKD) has become a public health burden worldwide for its increasing incidence and prevalence, high impact on the health related quality of life (HRQoL) and life expectancy, and high personal and social cost. Patients with advanced CKD, in dialysis or not, suffer a burden from symptoms very similar to other chronic diseases and have a life span not superior to many malignancies. Accordingly, in recent years, renal palliative care has been recommended to be integrated in the traditional care delivered to this population. This research provides an updated overview on renal palliative care from the relevant literature.

Resumo Este estudo analisa os comportamentos relacionados ao estilo de vida de adolescentes em Recife, Brasil. Estudo transversal com dados do Estudo de Riscos Cardiovasculares em Adolescentes (ERICA). 2.400 estudantes de 12 a 17 anos foram entrevistados. Foram analisadas as prevalências de atividade física, comportamento alimentar, tabagismo e consumo de álcool. O teste Qui-quadrado e Intervalo de confiança 95% (IC95%) foram usados para avaliar a significância estatística das medidas. Observou-se 60% dos adolescentes com comportamentos alimentares inadequados quanto ao consumo de café da manhã, água/dia e refeições em frente à TV. Cerca de 40% (IC95%: 39,7-45) não realizavam refeições com os pais ou responsáveis. A prevalência de inatividade física foi de 52,4% (IC95%: 50-55). Adolescentes do sexo feminino foram mais inativas (68,7%; IC95%: 65-72) em relação aos meninos (36,4%; IC95%: 33-40). Adolescentes das classes econômicas D e E foram os mais inativos (60,7%; IC95%: 46-73). O consumo de bebida alcoólica foi de 18,7% (IC95%: 2,6-5,6) e o tabagismo foi de 3,8% (IC95%: 2-6) dos indivíduos. Comportamentos alimentares inadequados e a inatividade física foram os principais domínios responsáveis por um estilo de vida não saudável, seguidos pelo consumo de álcool e tabagismo.

Abstract This study analyzes the behavior patterns related to the lifestyle of adolescents in Recife, Brazil. A cross-sectional study was conducted with data from the Cardiovascular Risk Study among Adolescents (ERICA) and 2400 students aged 12 to 17 were interviewed. The prevalence of physical activity, eating behavior, smoking and alcohol consumption were analyzed. The Chi-square test and 95% confidence interval (95%CI) were used to evaluate the statistical significance of the measurements. It was observed that 60% of the adolescents presented inadequate eating behaviors regarding the consumption of breakfast, daily water intake and meals eaten in front of the TV. About 40% (95%CI: 39.7-45) did not sit down to meals with their parents or guardians. The prevalence of physical inactivity was 52.4% (95%CI: 50-55). Female adolescents were more inactive (68.7%, 95%CI: 65-72) than males (36.4%, 95%CI: 33-40). Teenagers of economic classes D and E were the most inactive (60.7%, 95%CI: 46-73). Alcohol consumption was 18.7% (95%CI: 2.6-5.6) and smoking was prevalent in 3.8% (95%CI: 2-6) of the individuals. Inadequate eating behaviors and physical inactivity were the main areas responsible for an unhealthy lifestyle, followed by alcohol consumption and smoking.

RESUMO A história natural da doença e o tratamento de pacientes após a COVID-19 ainda se apresentam em construção. Os sintomas são persistentes, mesmo em casos leves, e as consequências decorrentes da infecção incluem fadiga, dispneia, taquicardia, perda de massa muscular e diminuição da capacidade funcional. Sobre a reabilitação cardiopulmonar, parece haver melhora na capacidade funcional, na qualidade de vida e no prognóstico com o Teste da Caminhada de 6 Minutos, sendo este utilizado como avaliador prognóstico e terapêutico. Assim, o objetivo deste relato de casos é descrever a experiência de quatro casos, de diferentes gravidades, que realizaram um programa de reabilitação cardiopulmonar pós-COVID-19, avaliados com Teste da Caminhada de 6 Minutos, força muscular periférica e duplo produto em repouso, para verificar o efeito da reabilitação após 3 meses de protocolo de, no mínimo, 300 minutos por semana. Os quatro casos apresentaram aumento da distância percorrida no teste da caminhada entre 16% e 94%. Houve aumento da força muscular periférica em 20% até seis vezes seu valor inicial, e a redução do duplo produto em repouso variou entre 8% e 42%. O programa de reabilitação cardiopulmonar apresentou impacto positivo nos casos acompanhados, com melhora da capacidade funcional, mesmo com a variabilidade da gravidade dos casos pós-COVID-19.

ABSTRACT The natural history of the disease, and the treatment of post-COVID-19 patients, are still being built. Symptoms are persistent, even in mild cases, and the infection consequences include fatigue, dyspnea, tachycardia, muscle loss, and reduced functional capacity. Regarding cardiopulmonary rehabilitation, there seems to be an improvement in functional capacity, quality of life, and prognosis with the 6-Minute Walk Test used as a prognostic and therapeutic evaluator. Therefore, this case series report aims to present our experience with four cases of different severity levels, involved in a post-COVID-19 cardiopulmonary rehabilitation program. These patients were assessed with the 6-Minute Walk Test, peripheral muscle strength, and double product at rest, to assess the results after a three-month rehabilitation protocol of at least 300 minutes per week. The four patients had their distance covered during the walk test increased between 16% and 94%. Peripheral muscle strength was improved by 20% to six times the baseline values, and double product at rest was reduced by 8% to 42%. The cardiopulmonary rehabilitation program had a positive impact on these cases, improving functional capacity despite the different severity levels in these post-COVID-19 cases.

Abstract Streptococcus pneumoniae is a major cause of severe invasive disease associated with high mortality and morbidity worldwide. To identify the serotypes most commonly associated with infection in adults in Argentina, 791 pneumococcal isolates from 56 hospitals belonging to 16 provinces and Buenos Aires city were serotyped. The isolates were submitted as part of a National Surveillance Program for invasive pneumococcal disease in adults, which started in 2013. Serotypes 3, 8, 12F, 7F and 1 were the most prevalent among adult patients. During the study period there was no significant difference in serotype distribution between the age groups studied (18-64 and >65 years old), except for serotype 1, 3 and 23A. Most prevalent serotypes in pneumonia were serotype 7F, 1, 12F, 8, and 3. When the clinical diagnosis was meningitis, serotype 3 and 12F were the most prevalent, whereas when the diagnosis was sep-sis/bacteremia the most prevalent was serotype 8. In this work, for the 18-64-year-old group, PPSV23 and PCV13 serotypes accounted for 74.56% and 44.54% respectively of the cases in the studied period. On the other hand, for the >65-year-old group, these serotypes represented 72.30% and 41.42% respectively. The aim of this work was to establish the knowledge bases of the serotypes that cause invasive pneumococcal diseases in the adult population in Argentina and to be able to detect changes in their distribution over time in order to explore the potential serotype coverage of the vaccines in current use.

Resumen Streptococcus pneumoniae es una causa importante de enfermedad invasiva grave asociada con una alta mortalidad y morbilidad en todo el mundo. Para identificar los serotipos principales asociados con la infección en adultos en Argentina, 791 aislamientos de neumococo de 56 hospitales pertenecientes a 16 provincias y la ciudad de Buenos Aires fueron serotipificados. Los aislamientos fueron remitidos como parte del Programa Nacional de Vigilancia para la enfermedad neumocócica invasiva en adultos, que comenzó en 2013. Los serotipos 3, 8, 12F, 7F y 1 fueron los más prevalentes. Durante el período de estudio no hubo diferencias significativas en la distribución de serotipos entre los dos grupos de adultos estudiados (18-64 y >65 años), excepto para los serotipos 1, 3 y 23A. Los serotipos más prevalentes en casos de neumonía fueron 7F, 1, 12F, 8 y 3. Cuando el diagnóstico clínico fue meningitis, los serotipos 3 y 12F fueron los más prevalentes. Y el serotipo 8 fue el más prevalente en la sepsis/bacteriemia. En el grupo de 18-64 años, los serotipos PPSV23 y PCV13 representaron, respectivamente, el 74,56 y el 44,54% de los casos de enfermedad invasiva en el período estudiado. En el grupo de >65 años, estos serotipos representaron el 72,30 y 41,42%, respectivamente. Es importante conocer los serotipos causantes de infecciones neumocócicas invasivas en la población adulta en Argentina y detectar eventuales cambios en su distribución a lo largo del tiempo, para explorar la potencial cobertura de las vacunas utilizadas.

Resumo Campanhas publicitárias influenciam o comportamento de consumidores utilizando conceitos-chave que as ciências comportamentais têm mapeado através de experimentos controlados e randomizados. O objetivo deste artigo de pesquisa bibliográfica é, portanto, o de apresentar, articular e discutir as principais teorias da psicologia social referentes tanto à mudança de atitudes quanto de comportamentos. Mais especificamente, este estudo busca reduzir a distância entre o arcabouço teórico-conceitual da psicologia e a prática profissional do criativo publicitário, propondo uma interface entre esses dois universos e indicando como insights psicológicos podem ser aplicados para aumentar a efetividade dos anúncios publicitários.

Abstract Advertising campaigns influence consumer behavior using key concepts that the behavioral sciences have mapped using controlled and randomized lab experiments. The aim of this bibliographic research article is, therefore, to present, articulate and discuss the main theories of social psychology regarding both attitude and behavior change. More specifically, this study seeks to reduce the distance between the theoretical-conceptual framework of psychology and the professional practice of advertising production, proposing an interface between these two universes and offering suggestions on how psychological insights could be applied to improve advertising effectiveness.

El objetivo de este artículo de investigación bibliográfica es, por lo tanto, presentar, articular y discutir las principales teorías de la psicología social con respecto a los cambios de actitudes y comportamientos. Más específicamente, este estudio busca reducir la distancia entre el marco teórico-conceptual de la psicología y la práctica profesional de la publicidad creativa, proponiendo una interfaz entre estos dos universos e indicando cómo se pueden aplicar las percepciones psicológicas para aumentar la efectividad de la publicidad.

Abstract The lack of information on the occurrence of species in a region limits the understanding of the composition and structure of the local community and, consequently, restricts the proposition of effective measures for species conservation. In this study, we researched the reptiles in the Duas Bocas Biological Reserve (DBBR), Espírito Santo, southeastern Brazil. We analyzed the parameters of the local community, such as richness, composition, and abundance of species. We conducted samplings from August 2017 to January 2019, through active search. We performed the samplings in nine standard plots of 250 meters in length. All individuals located in the plots or occasionally on the trails were registered. To evaluate sample effort to characterize the reptile community, we performed an accumulation curve of species, and to update the DBBR reptile list, we used as secondary data specimens deposited in collections and previously published studies. Considering primary and secondary data, we recorded 38 species, one chelonia, 13 lizards, and 24 snakes. Our study showed a richness of 15 additional species to the previous list of reptiles, increasing by about 40% the known richness to the area. We concluded that the DBBR holds a high richness of reptile species, representing 12% of the richness of reptiles of the Atlantic Forest and with a considerable number of endemic species in this biome. This suggests that the DBBR is an important forest fragment constituting a reservoir of the biodiversity of the reptiles of the Atlantic Forest.

RESUMO Introdução O cuidado paliativo é uma abordagem voltada para alívio do sofrimento, controle de sintomas e melhora da qualidade de vida. Deve ser oferecido em conjunto com o tratamento padrão de qualquer doença que ameace a continuidade da vida, como, por exemplo, a infecção pela Covid-19. Discussão Os princípios bioéticos e as estratégias utilizadas pela medicina paliativa podem auxiliar os nefrologistas no cuidado dos pacientes com disfunção renal, que, além de serem do grupo de risco para evolução mais grave da infecção por coronavírus, enfrentam as dificuldades do isolamento no seguimento do tratamento dialítico e ambulatorial. Essas ferramentas são: I) tomada de decisão compartilhada, que proporciona a participação do paciente e dos familiares como facilitadores na sistematização do raciocínio da equipe, além de respeitar o princípio da autonomia; II) manejo de sintomas, que deve ser prioridade para a garantia do alívio do sofrimento mesmo em momento de isolamento social; III) habilidades em comunicação, sendo possível amenizar dificuldades em anunciar más notícias ou decisões complexas através de técnicas de comunicação; IV) assistência ao luto, em que, em situações agudas como a pandemia, de perdas inesperadas, a importância do acolhimento dos profissionais de saúde torna-se ainda maior. Conclusão Os princípios dos cuidados paliativos são essenciais para enfrentar os desafios de uma crise humanitária, que causa sofrimento ao ser humano em todas as dimensões e exige a construção de estratégias que possam manter os pacientes assistidos, confortáveis e com medidas proporcionais à sua condição clínica e às suas preferências.

ABSTRACT Introduction Palliative care is an approach aimed at relieving suffering, controlling symptoms and seeking to improve quality of life. It must be offered in conjunction with standard treatment for any disease that threatens the continuation of life, such as a Covid-19 infection. Discussion The bioethical principles and strategies used by palliative medicine can assist nephrologists in the care of patients with renal dysfunction, who face the difficulties of isolation at the beginning and follow-up of dialysis in outpatient treatment, and those who are at risk for a more serious disease progress. Some of them: - a Shared decision making, which enables the patient and family to participate as facilitators in the systematization of the team’s reasoning, in addition to respecting the principle of autonomy; - Symptom Management: which should be a priority to ensure relief of suffering even in times of social isolation; - Communication skills: making it possible to alleviate suffering in announcing bad news or complex decisions through communication techniques;; - Bereavement assistance: which in acute situations such as the pandemic, causing unexpected losses, the importance of sympathy from healthcare professionals becomes even greater. Conclusion The principles of palliative care are essential to face the challenges of a planet-wide crisis, which raises human suffering in all dimensions, and which requires the construction of strategies that can keep patients assisted, comfortable and with measures proportional to their clinical condition and preferences.

ABSTRACT OBJECTIVE To determine the prevalence of cigarette use among adolescents and to identify associated health risk behaviors. METHODS This is a cross-sectional study with a representative sample, composed of 1059 adolescents between 13 and 19 years old, enrolled in primary and secondary public schools of Olinda, Pernambuco, in 2014. Information was obtained through self-administered questionnaires (validated version of YRBS 2007). Cigarette experimentation was defined as smoking at least once in life. Adolescents who smoked at least one day within 30 days prior to the survey were considered current smokers. Most students were female and 16 years old or older. RESULTS Almost 30% used it in life and about 10% smoked within the 30 days before the survey. Suicidal ideation (PR = 1.51, 95%CI 1.25–1.82), alcohol use (PR = 1.41, 95%CI 1.03–1.92), marijuana (PR = 1.64, 95%CI 1.37–1.96), excessive alcohol consumption (PR = 1.57, 95%CI 1.15–2.16) and sexual experience (PR = 1.78, 95%CI 1.43–2.21) have increased the risk of using cigarettes. Feelings of sadness (PR = 1.70, 95%CI 1.22–2.36), alcohol use (PR=2.40, 95%CI 1.12–5.12), excessive alcohol consumption (PR = 2.5, 95% CI 1.24–5.38), marijuana (PR = 2.31, 95%CI.57–3.39) and cocaine (PR = 1.99, 95%CI.32–3.01) increased the risk of cigarette use within the 30 days before the survey. CONCLUSIONS Cigarette use among adolescents from Olinda was high, being considered higher than the national prevalence. Possible factors associated with cigarette use were drug use (alcohol, marijuana, and cocaine) and behaviors related to sexual experience, feelings of sadness and suicidal ideation.
