INTRODUCTION: The pneumothorax is consequence of the most frequent air leak in the neonatal period and its treatment is based mainly on severity of clinical manifestations. Oxygen treatment at high concentrations (Nitrogen washout) to those with mild to moderate clinical manifestations has been a therapy used to achieve its rapid resolution; However, its usefulness is controversial. CLINICAL CASES: 36-week neonates that presented spontaneous pneumothorax of 30-45%, associated with mild to moderate respiratory distress. Therefore, oxygen was indicated at high concentrations with adequate clinical response. CONCLUSIONS: The use of oxygen at high concentrations for the treatment of pneumothorax has not generated advantages by recent studies. On the contrary, there may be side effects from hyperoxia and other unfavorable clinical outcomes. In spite of this, there is likely to exist trends for use, with apparent good results. However, for recently studies, this intervention should be avoided and must follow up on the results of pneumothorax in each unit. [ABSTRACT FROM AUTHOR]

This study explores the media practices of Peruvian internet users based on their self- perceived educational level. The purpose is to provide an original theoretical perspective on the formation of media assemblages, shaped by the uses and interactions of specific social groups with media outlets. Utilizing a custom questionnaire, grounded in an updated version of the Uses and Gratifications Theory, administered to a sample (n=465) of users from various age groups and socioeconomic backgrounds, we examine the similarities and differences in these media assemblages and their impact on users' agency as critical media consumers. The results reveal that the national context, characterized by technological disparities and the COVID-19 pandemic, has influenced consumption practices. The smartphone stands out as the most widely used device, valued for its immediacy and diverse content. Both less educated and highly educated groups resort to it for information, education, and entertainment. Television also plays a significant role, serving as entertainment for older generations and a source of information for higher socioeconomic levels. The choice of streaming services among different income groups reflects the influence of connectivity and bandwidth. Information consumption is driven by curiosity, while entertainment is used for learning and following trends. Furthermore, there is little planning involved in entertainment and information consumption, although educational content is more planned among the highly educated group. This difference may be linked to access opportunities for educational materials, suggesting avenues for future research. [ABSTRACT FROM AUTHOR]

Among the studies on private libraries in Peru in the Modern Age, there are no studies focusing on the circulation of books by Portuguese authors or printed in Portugal. This article therefore proposes a comparative approach to the subject, considering two topics: the complexity of the circulation of books between Lis- bon, Seville and Lima; and the presence of books by Portuguese authors in Peru printed in Lisbon. For this purpose, we will use general inventories of booksellers and records of books in the fleets, as well as primary sources: inventories of goods in the context of proceedings of the Court of the Holy Office and private epistolary writings of Portuguese merchants. We will also use Portuguese guides to works printed in Portugal in the 16th and 17th centuries and the catalog of existing books in the National Library of Portugal. [ABSTRACT FROM AUTHOR]

The genus Passiflora accounts for 17% of global flavonoid production, and several strategies have been explored to increase their production in these plants, given the growing demand for these metabolites. The aim of this study is to examine the published literature on the correlation between flavonoid concentrations in Passiflora genus leaves and factors such as microorganism presence, soil fertility, fertilizer use, soil conditioners, agronomic practices, weather patterns, and plant phenology. The search was conducted across nine databases. Web of Science, Nature, Agris, Dialnet, SciELO, Science Database-ProQuest, Scopus (Elsevier), Springer, and EBSCOhost and two search engines: Google Scholar and Semantic Scholar, obtaining 19 indexed articles. The results indicate that treatments incorporating a single biotic or abiotic factor in the crop lead to a 380% increase in the production of flavonoids at the leaf level, while the combination of different biotic and abiotic factors leads to a 491% increase in the production of this group of metabolites at the leaf level. It is essential to assess the integrated agronomic management of Passiflora sp. to increase the concentration of these metabolites in the leaves of productive branches with fully ripened fruits ready for harvest (BBCH code 89), without losing the possibility of using the current main product of the crop.

Little has been written about human rights guarantees in Crimea, a territory annexed by Russia since 2014. Furthermore, approaches to the transnational networks that press Russia's obligations compliance towards the inhabitants of the peninsula are precarious. This article analyzes the agency of transnational advocacy networks regarding human rights violations in Crimea, between March 2014 and November 2021, as a precedent to the new phase of annexations in Ukraine in February 2022. Using notions from international norms, civil and political rights, and transnational networks, and based on primary and secondary sources, we describe notions of human rights in Ukraine and analyze the achievements of these transnational networks. The article shows that there is a limited institutionalization of the kind of environment that can foster the consolidation of human rights advocacy organizations in Ukraine, that agents within the network have very low coordination levels and that there have been very few changes in Russia's oppressive behavior.

The Uses and Gratifications Theory is one of the most productive areas of research in the field of Communication. Since its inception in the 1940s, it has evolved and incorporated new variables through applications in various media, especially social media, and demographic contexts. This article, based on a systematized review of 88 works published in reference databases, describes the objects of study, methodologies, and forms of application of this theory from the year 2020 to 2022. The results demonstrate its diverse forms of application while indicating its relevance as a useful theoretical framework from which to explore and report on people's motivations and needs for using various media, as well as their perceived effects. In particular, the recurring population in these studies are young people, corresponding with the social media and platforms being investigated. Likewise, surveys are the technique predominantly used. However, it is noted that most of the time, authors barely mention the Uses and Gratifications Theory without proposing a relevant conceptual or methodological development that allows for discussion of its limitations, deepening its scope, and updating its possibilities.

Objective: Muscle stretching is applied with the purpose of increasing range of motion. Different techniques are used for this purpose, including proprioceptive neuromuscular facilitation (PNF) and dynamic stretching, but it is still unclear which one is more effective. The objective of this research was to estimate the efficacy of the hold-relax technique compared to dynamic stretching on hamstring flexibility in healthy young adults. Methodology: Randomized controlled trial with blinding, consisting of two intervention arms. The study included a total of 32 young adult volunteers aged 18 to 30 years, who were randomized into two intervention groups: PNF (n = 16) and dynamic stretching (n = 16). Knee joint flexibility was assessed using the popliteal angle measured with a goniometer. Results: The mean age, weight, height, and body mass index were found to be equivalent, indicating comparable groups. No significant differences were found between the stretching groups in the adjusted means, with a mean difference of -2.09 (95 % CI -7.05 to 2.87). Conclusions: Both dynamic stretching and PNF demonstrated an increase in knee range of motion, with both stretching techniques showing differences from the baseline. No significant differences were found between the stretching groups. [ABSTRACT FROM AUTHOR]

Introduction: the classification of cardiovascular risk allows the appropriate selection of exercise, through individualized assessments, and the generation of recommendations based on evidence. This study determined cardiovascular risk in a group of adults and older adults, using the stratification tool for exercise prescription of the American Heart Association (AHA), pointing out its recommendations, and those of the European Society of Cardiology (ESC). Methods: cross-sectional study, based on surveys of individuals belonging to a physical conditioning program. Cardiovascular risk was determined, a univariate and bivariate analysis was performed. Based on the results, appropriate exercise recommendations were described according to the AHA and the ESC, taking into account additional characteristics such as type and intensity, review mode. Results: the population was 62 participants, 84% (n=52) were women. The mean age was 65.73 ± 10.5 years. 51.6% were older adults (≥ 65 years). 45.2% had a history of hypertension and overweight, followed by diabetes (41.9%), dyslipidemia (33.9%) and valvular disease (21%). The calculated cardiovascular risk was: Class A: 25.8% (n=16); Class B: 29.0% (n=18); Class C: 19.4% (n=12), and Class D: 25.8% (n=16). There was a higher prevalence of hypertensive patients (39.3%) in class D (p = 0.016). Conclusion: the application of the cardiovascular risk classification strategy emerges as a key element to support informed decision making, generate substantial health benefits, and reduce the risk of complications.

The paper examines the life of Antônio Varela, born in 1805, a pardo man whose mother was a freed woman, who became captain of the National Guardo of Brazilian Imperial State, a slave master, and a major landowner in the village of Piranga, a former district of the municipality of Mariana in Minas Gerais. This paper discusses his relationships with family, god parentage, and neighbors in the area where he owned land. In doing so, it highlights the routes of social mobility and economic ascension strategies, and explores the geographically-structured quotidian sociability that circumscribed his life course. This paper presents a cartography of freedom and socioeconomic ascension, emphasizing the new spaces of sociability that enabled Varela to raise his standing in the local hierarchy.
