Algunas reflexiones para discutir los orígenes de la educación del Arquitecto Peruano
Authors: Espejo Chávez Alvaro Jesús
Published: July 2022

The main objective of this essay is to expose some reflections that add to the discussion about the education of the Peruvian architect, through the review of issues associated with the understanding of Peruvian history under a frame of reference that values the previous autonomous life. contact with the West, the origin of architecture in our country, the presence of architects in the pre-Hispanic world and the training of the professional architect beyond the formal sphere. Thus, from a critique of colonial limits and on the basis of Coombs's proposal to classify the types of education, it has been possible to establish a reading that integrates the various manifestations developed in the formal and non-formal spheres of education.

Authors: Hu Rivas Gloria Maney , Shiguay Guizado Giomar Arturo
Published: July 2022

Mastery of mathematics represents a great challenge at different educational levels, so it is necessary for students to learn to solve problems from their daily lives. The objective of this study is to analyze and highlight the relevance of the development of mathematical skills from experiential games that develop the ability to solve problems of quantity and shape, movement and location. For this, a bibliographic review of 15 books and 25 national and international articles published between 2012 and 2021 was carried out; scientific dissemination spaces such as Scopus, ERIC, SciELO and academic Google were considered. Information organizers were used which allowed identifying the importance of mathematical skills and their elements; the conceptualization of experiential games was highlighted. What was analyzed allowed us to conclude that it is important to put into practice educational strategies that contain experiential games for the development of mathematical skills in children at the initial level.

Currently, as a result of the consequences of the pandemic caused by the SARS CoV-2 virus, several reflections and reports have been generated in the field of education in Latin America and the Caribbean, related to the quality of education and its contribution to the emotional intelligence of society. For this reason, this study has carried out a systematic review of the research developed in these geographical areas in order to find out about the studies associated with the impact of education on the development of emotional intelligence.The aim of the study was to provide the scientific community with data to access the state of the question.  The scientific literature indexed in Scopus, EBSCO Host and OARE from 2018 to 2021 was used as a database, obtaining a total of 36 scientific articles. The research included in the review we examined their geographical origin, year of publication, methodology, type of measure used, conclusions reached and coincidences between them. These have been subsequently analysed. Finally, the results show the little scientific production on the subject of study and the complexity of the emotional intelligence variable, as it is multidimensional in nature.

The mechanisms of lipid oxidation under the application of nitroglycerine (NG) were studied in isolated rat heart and liver mitochondria. Dose-dependent formation of diene conjugates (DC), leukotriene C4 (LTC4) and thromboxane B2 (TxB2) was shown. To disclose the mechanisms regulating lipid peroxidation in mitochondria, we studied the effect of NG application on the formation of prooxidants (H2O2 and free Fe2+), as well as xanthine oxidase and mtNOS activity as main sources of ROS and RNS. Based on the correlation dependences, we have found that DC, LTC4, and TxB2 formation was strongly dependent on hydroperoxide production and free divalent iron release in mitochondria. Also, DC formation exhibited the dependence on Ca2+ uptake in mitochondria. No dependence of lipid oxidation on xanthine oxidase activity was found. In heart, but not liver mitochondria, DC, LTC4, and TxB2 exhibited strong dependence on mtNOS activity, but were independent of nitrosothiols formation. This indicated that lipid oxidation was independent of direct protein nitrosylation caused by NG application. No dependence of lipid oxidation on mtNOS activity in liver was found, which agreed with much higher mtNOS activity in heart mitochondria, and suppression of mtNOS activity in liver mitochondria at high doses of NG. So, we came to the conclusion that under NG application ROS overproduction and free Fe2+ release promoted both enzymatic and non-enzymatic lipid oxidation in heart and liver mitochondria. Also, we hypothesized that RNS overproduction due to the elevated mtNOS activity in the heart could largely contribute to lipid peroxidation and promote much faster increase in the formation of lipid oxidation products in heart as compared to liver mitochondria, especially at high doses of NG. Obtained correlation dependences allowed us disclose free iron, hydroperoxide, and mtNOS activity as principal factors affecting lipid peroxidation in mitochondria under NG application.

This investigation is aimed at studying the effect of abdominal surgical trauma (laparotomy) on markers of surgical stress and acute phase response as well as markers of carbohydrate and lipid metabolism under lipopolysaccharide (LPS) -induced systemic inflammatory response (SIR). Male Wistar rats were divided into 4 groups: 1st (control) group included “pseudooperated” animals (the procedure included the administration of anesthesia, epilation, fixation of animals, compression of the skin of the abdomen with Mikulicz’s clamp by one click); the 2nd group included the rats, which were injected Salmonella typhi (in a dose of 0.4 μg/kg body weight 3 times during the 1st week and once a week for the next 7 weeks) before performing the “false operation”; the 3rd group was made up of the rats after laparotomy; and the 4th group involved the rats after laparotomy performed under LPSinduced SIR. The markers were assessed in 7 days following the “pseudo-operation” or laparotomy. The results obtained have demonstrated the combined effect of laparotomy and LPS-induced SIR was accompanied by a significant increase in the marker of surgical stress, the concentration of cortisol in blood plasma, which significantly exceeded the values of the groups 2 and 3 – by 61.8 and 25.1%, respectively. However, the content of acute-phase protein ceruloplasmin, an acute phase reactant, in the serum remained at the level of the 2nd group. Under these conditions, the concentration of very low-density lipoprotein cholesterol and triglycerides significantly exceeded the relevant values in the 2nd and 3rd groups. The combined effect of surgical trauma and LPS-induced SIR considerably reduced the activity of constitutive isoforms of NO-synthase, which was significantly lower, by 41.7%, than the value in the group 2, and by 41.7% lower than in the group 3. At the same time, the total activity of this enzyme and the activity of its inducible isoform were consistent with the values of the 2nd group. This was accompanied by the development of decompensated lipid peroxidation (with a considerable decrease in the blood antioxidant potential).
Management of Heart Failure in Patients with Chronic Kidney Disease
Authors: Ryan David K , Banerjee Debasish , Jouhra Fadi
Published: July 2022

Chronic kidney disease (CKD) is increasingly prevalent in patients with heart failure (HF) and HF is one of the leading causes of hospitalisation, morbidity and mortality in patients with impaired renal function. Currently, there is strong evidence to support the symptomatic and prognostic benefits of β-blockers, renin–angiotensin–aldosterone inhibitors (RAASis), angiotensin receptor-neprilysin inhibitors (ARNIs) and mineralocorticoid receptor antagonists (MRA) in patients with HF and CKD stages 1–3. However, ARNIs, RAASis and MRAs are often suboptimally prescribed for patients with CKD owing to concerns about hyperkalaemia and worsening renal function. There is growing evidence for the use of sodium–glucose co-transporter 2 inhibitors and IV iron therapy in the management of HF in patients with CKD. However, few studies have included patients with CKD stages 4–5 and patients receiving dialysis, limiting the assessment of the safety and efficacy of these therapies in advanced CKD. Interdisciplinary input from HF and renal specialists is required to provide integrated care for the growing number of patients with HF and CKD.
Der Einfluss der Black Lives Matter-Bewegung auf die frankophone Toponymie
Authors: Herling Sandra
Published: July 2022

Die insbesondere seit 2020 international wirksame Black Lives Matter-Bewegung konnte ohne Zweifel eine kritische Reflexion über rassistische Begebenheiten anregen. Doch nicht nur politisch motivierter Rassismus oder alltägliche rassistische Handlungen stehen im Fokus der Black Lives Matter-Bewegung, sondern auch die sprachliche Manifestierung von Rassismus. Aus onomastischer Perspektive ist nun die Tatsache interessant, dass immer mehr Ortsnamen in den Mittelpunkt der kritischen Debatte rücken. Es handelt sich hierbei um Namen, deren Signifikant für viele Rezipient:innen eine rassistische Konnotation aufweist. Als Beispiele seien der Brüsseler Tunnelname Leopold II Tunnel, der senegalesische Verkehrsplatzname Place de l’Europe oder das Québecer Hydronym Rivière du Nègre genannt. Wie die toponymischen Beispiele verdeutlichen, wird die rassistisch empfundene konnotative Bedeutung über die an die europäische Kolonialzeit assoziierten Namenbestandteile oder über die Transparenz von bestimmten Lexemen wie z.B. nègre transportiert.

Der vorliegende Beitrag setzt sich zum Ziel, eine erste Bestandsaufnahme zur Debatte über rassistisch konnotierte Toponyme in frankophonen Räumen zu präsentieren. Im Mittelpunkt der Darstellungen sollen zunächst die als rassistisch empfundenen Ortsnamen identifiziert werden. Im Anschluss daran werden erfolgte und in der Diskussion stehende Umbenennungsprozesse in der europäischen und außereuropäischen Frankophonie beschrieben. Hierzu werden Fallbeispiele aus Kanada/Québec, Belgien, Frankreich, aus dem Senegal und aus der Côte d’Ivoire berücksichtigt.

Authors: Busenkov Aleksei , Kholodov Eduard , Novikov Roman , Pozin Boris
Published: July 2022

With the development of modern technologies in medical organizations, there is an opportunity to modernize existing methods of monitoring public health and detecting diseases. The use of telemedicine can reduce costs and increase the efficiency and accessibility of medical services including monitoring the state of health by remote (outside of medical and preventive institutions) registration and processing of ECG that helps to detect diseases in the initial stages. In this paper, we propose an approach to displaying data to users of telemedicine systems for independent (without medical staff) early detection of diseases by ECG. This approach can be used in the development of a graphical interface for telemedicine systems for the early detection of diseases by ECG.

Published: July 2022

Ikan nila merupakan ikan budidaya yang disukai oleh masyarakat karena dagingnya yang gurih dan lezat. Untuk peningkatkan produksi ikan nila diperlukan pakan yang cukup, baik kualitas maupun kuantitasnya. Pakan merupakan komponen biaya operasional utama pada budidaya ikan nila yang diperkirakan mencapai 40%-60%. Untuk mengatasi hal tersebut diperlukan teknologi yang dapat menekan biaya operasional dalam sistem budidaya. Tujuan dari penelitian ini adalah mengevaluasi frekuensi pemberian pakan yang berbeda terhadap pertumbuhan dan sintasan ikan nila merah (Oreochromis niloticus) yang dipelihara dengan sistem bioflok. Metode yang diterapkan adalah eksperimen dengan empat perlakuan dan tiga kali ulangan. Perlakuannya adalah frekuensi pemberian pakan pelet yaitu (A) 1 kali/hari, (B) 2 kali/hari, 3 kali/hari, dan 4 kali/hari. Ikan nila ukuran 3,71 ± 0,11 cm dan bobot 4,49 ± 0,021 g dipelihara selama 56 hari dalam bak 100 L dengan padat tebar 16 ekor/bak. Ikan dipelihara dengan teknologi bioflok dan diberikan pakan setiap harinya sebanyak 5%/berat biomasa/hari. Hasil penelitian menunjukkan bahwa pemeliharaan ikan nila merah pada sistem bioflok dengan frekuensi pemberian pakan yang berbeda berpengaruh nyata (P<0,05) terhadap performa pertumbuhan, sintasan, dan efisensi pakan. Perlakuan frekuensi pemberiaan pakan 2 kali/hari merupakan perlakuan terbaik menghasilkan pertumbuhan bobot mutlak 23,07 ± 0,89 g; laju pertumbuhan harian 3,23 ± 0,05%; sintasan 91,66 ± 3,60%; dan efisensi pakan 96,73 ± 6,70%.Tilapia (Oreochromis niloticus) is a cultured fish that is favored by the public, because of its delicious meat and high protein content. To increase production, quality, and quantity of feed is needed, feed is the main component in the cultivation system and it is estimated that 40%-60% of the costs incurred in maintaining tilapia are needed. To overcome this, technology is needed that can reduce operational costs in fish culture. The purpose of this study was to evaluate the growth and survival of red tilapia with different feeding frequencies reared with a biofloc system. The research method applied was experimental with four treatments and three replications. The treatment was the frequency of feeding, namely (A) 1 time/day, (B) 2 times/day, 3 times/day, and 4 times/day. Tilapia were reared for 56 days in a 100 L tank with a stocking density of 16 fish/tank. Initial size 3.71 ± 0.11 cm and weight 4.49 ± 0.021. Tilapia are reared with biofloc technology and given daily feed of 5%/weight of biomass/day. The results showed that rearing red tilapia with different feeding frequencies in the biofloc system had a significant effect (P<0.05) on growth performance, survival, and feed efficiency. Treatment B with a frequency of feeding 2 times/day was the best, with absolute growthof 23.07 ± 0.89 g, daily growth rate of 3.23 ± 0.05%, survival rate 91.66 ± 3.60%, and feed efficiency 96.73 ± 6.70%.
Principles and practice of cross-referencing in paper and electronic dictionaries with specific reference to African languages
Authors: Prinsloo Danie , van Graan Neill Daniel
Published: July 2022

In the first section of this article, the basic principles and practices of cross-referencing are discussed mainly in reference to paper dictionaries. This is followed by a section on cross-referencing in electronic dictionaries. Although the principles underlying cross-references in paper and electronic dictionaries are the same, many, more sophisticated options, which the authors call ‘true electronic features’, are available to the lexicographer in the computer era. Cross-references are used on a much larger scale in electronic dictionaries since almost every word or element in a dictionary article can be cross-referenced to an address where the user can find more information. Cross-referencing in electronic dictionaries largely revolve around multiple uses of hyperlinking. In the final section, cross-referencing, or the lack thereof, will be discussed for African language dictionaries. Typical instances where cross-references are required in dictionaries for these languages will be outlined and the compilation of model entries will be attempted.
Words, dictionaries and sociology
Authors: Li Lan
Published: July 2022

The COVID-19 pandemic has lasted for more than one year with a devastating effect on the whole world. This paper illustrates word-formation approaches and semantic webs of COVID-19 vocabulary that is said to number more than 1000 new words; it also discusses significant events that created ‘coroneologisms’. In this connection, the paper takes a corpus-based approach towards content analysis and semantic relationship networks by studying the massive data associated with the pandemic: news reports, government documents, international policies, science papers, social media posts and others. Three online mega-corpora and self-collected data were analysed from the lexicological perspective, including affixation, compounding, blending, acronyms, and word meanings associated with common words. The paper also reifies the efforts of lexicographers, especially those of the Oxford English Dictionary (OED), in recording this unprecedented catastrophe in human history. In using the semantic web, aspects of language are shown to have developed during this period. The broader purpose is to ascertain how language, as a social enterprise, has changed in tandem with empirically ascertainable social, political and scientific changes during the pandemic. The underlying belief advanced here is that the more in-depth study we conduct into COVID-19 (related) vocabulary, the more we can understand the pandemic and document its history.
Japanese neologisms in Chinese
Authors: Schmidt Christian , Chen Chien-shou
Published: July 2022

Japanese loanwords in Chinese are currently not accepted as legitimate loanwords in the general loanword framework (Haspelmath and Tadmor, 2009a), mainly because they are considered to be graphic loans (Masini, 1997; Tranter, 2009) and not sound-meaning borrowings. This paper formulates a counterargument, developed mainly from the perspective of the Chinese scholarship: it focuses on how graphemic borrowing impacts the judgment of loanwordness and the types of resolving strategies that have been developed. The origin of word form, word meaning, and the pathways of historical borrowing particularly stand out as non-linguistic factors of loanwordness. Based on a metaanalysis of 25 studies of Japanese loanwords in Chinese, the authors propose a typology of Japanese loanwords in Chinese that bridges the Western and the Chinese frameworks. To put forward a concrete example, we compile a list of 2,920 Japanese loanwords in Chinese, which are discussed by at least three scholars, ordered by degrees of agreement within the Chinese scholarship. We compare this list against the vocabulary list of the World Loanword Database and demonstrate that Wiebusch and Tadmor (2009), in ignoring Japanese loanwords, also omits numerous loanwords in Chinese. We echo Tranter (2009) in arguing that Japanese loanwords in Chinese can be classified as material borrowing, putting graphemic borrowing on the same footing with phonetic borrowing, since graphemic borrowing is not limited to, though preferred by, the Chinese writing system. We demonstrate this by comparing how writing systems impact borrowing.
Learners’ dictionaries and an English cultural keyword
Authors: Adamska-Sałaciak Arleta
Published: July 2022

Among culture-bound vocabulary items, we typically find names of realia, but also lexemes not immediately identifiable as such, but which are perhaps even more important as indications of culture specificity: words that reflect the ways of thinking and acting deemed appropriate in a given cultural milieu. This paper deals with one such item, which, according to Anna Wierzbicka (2006, 2014), is an essential component of Anglo values: the adjective fair in its moral sense. The analysis is meant to establish how successful dictionaries for learners of English are in rendering its nuances of meaning.
Embodied practice in a tidying up activity
Authors: Korenaga Ron , Mori Ippei , Sunaga Masafumi , Ikegami Satoru , Endo Tomoko
Published: July 2022

This article explores how collaborative tidying up activities in a family are accomplished and negotiations take place among family members. Employing ethnomethodology and conversation analysis on collected video data, we focus on the directive/response sequence and the incumbency of the category of ‘family’, which engenders responsibilities for family members. We consequently elucidate how the children’s responses reveal invalidation of the directive when they were not entitled to do so in terms of the responsibility and materiality of objects. We also explore how participants make the materiality of objects accountable through their verbal and embodied conduct in the tidying up activity.
‘Now it was meal’
Authors: Björk-Willén Polly
Published: July 2022

The overall aim of the present paper is to analyse and explore what frames a pretend play event as legal and recognizable to the participants, highlighting the children’s use of tense as an organizational device. The present video data are drawn from a single case study of two preschoolers’ interaction during a free play time event in a Swedish preschool. Influenced by ethnomethodological work on social actions, the analytical focus is on the participants’ methods of accomplishing and making sense of social activities. The use of tense proved to be the strongest contextualization cue to accomplish the switches between the ‘make believe’ and ‘the real’ domains, which demonstrated and organized what can and cannot be done in the pretend play scenario.
Clinical Evaluation of the Relationship Between Systemic Disease and the Time of Onset of Peri-Implantitis: A Retrospective Cohort Study
Authors: Seki Keisuke , Hasuike Akira , Hagiwara Yoshiyuki
Published: July 2022

The role of systemic diseases in the development and progression of peri-implantitis remains unclear and requires discussion from various perspectives. This retrospective cohort study aimed to evaluate whether the type of systemic disease affects the onset time of peri-implantitis. The cohort consisted of patients who underwent implant maintenance evaluations between January 1998 and June 2020. Information on age, sex, history of periodontal disease, smoking habits, body mass index, systemic diseases, implant placement sites, and diagnosis of peri-implantitis were obtained. The relationships between the time of onset of peri-implantitis and the medical history of systemic diseases were determined statistically by applying the Kaplan-Meier analysis method and log-rank test. A total of 216 implants in 89 patients (34 male and 55 female) were included in this study. The average patient age was 53.9 ± 11.8 years at the first visit, and the mean duration of maintenance was 7 years and 4 months. A total of 43 patients had medical histories and were assigned to the systemic disease group. In this group, the overall prevalence of peri-implantitis was 25.4% (29 of 114 implants). The medical history of systemic diseases (odds ratio [OR], 6.87; 95% confidence interval [CI], 2.37–19.9) and dental history of periodontitis (OR, 3.64; 95% CI, 1.25–10.6) were assessed as risk factors for peri-implantitis. A significant difference in the time of onset of peri-implantitis was confirmed between patients with systemic disease and healthy patients. Diabetes mellitus, osteoporosis, and hypertension had a significant impact on the earlier onset of peri-implantitis.
Multivariate conditional aging intensity functions and load-sharing models
Authors: BUONO Francesco
Published: July 2022

The aging intensity functions analyze the aging property quantitatively, in the sense that the larger the aging intensity, the stronger the tendency of aging. They are useful tools to describe reliability properties of distributions. In the literature, the aging intensity functions have been studied in the univariate and bivariate case but without considering the possibility of observing a dynamic history. In this paper, the concept of aging intensity function is extended to the multivariate case by the use of the multivariate conditional hazard rate functions. Some properties of those functions are studied and a focus on the bivariate case is performed. Finally, the multivariate conditional aging intensity functions are studied for the order dependent version of the time-homogeneous load-sharing model and a study on the comparison among surviving components in a system is provided.
The Third Age Universities in Russian Higher Education: Problem Area

Published: July 2022

Prolongation of business and social activity of older people is becoming a national-scale task, and Universities of the Third Age (U3A) are a noticeable global phenomenon of lifelong education, aimed at solving this problem. This paper outlines the problematic field of the Russian experience in the development of U3A on the basis of higher educational institutions. The author systematizes and subjects to comparative analysis the scattered evidence of the Russian experience of U3A as a form of the HE activity in the market of educational services, collected in secondary sources and from open data on the websites of universities. As key results this paper draws to conclusions that U3A in Russian universities are a new concept lagging world practices in terms of the scale and diffusion. Russian universities, even with sufficient funding, hardly create U3As struggling define U3As prospective for themselves. While creating U3As, they offer older students non-formal education aiming to create general cultural competencies, and repeat in this approach to the education content the Social Service Centre. This study allows to prove the importance of theoretical and practical development of the Russian model of U3A in universities, as well as to propose several management solutions. The main solutions are to rethink the role and functions of the U3A and to create them as divisions of leading universities to fulfil the strategic tasks of their development. U3A in the universities aim both at a new target market and at the implementation of the ‘third mission’ by the universities to ensure equal access to quality education beyond any, including age-related barriers.

The paper discusses the option of installing a load-bearing element inside a spherical Luneberg lens (LL). The presence of a metal element inside the LL will increase the structural rigidity of the spherical antenna and thereby expand the scope of use of the LL at various mobile communications and radar facilities with severe operating conditions. The influence of a metal rod inside the main spherical structure on the radiation pattern in two main planes in the linear polarization mode and on the diffraction pattern of the radiation field is estimated. The results of the analysis of the directional characteristics and the diffraction pattern of the LL radiation field were obtained using modeling in the Ansys Electronics Desktop (HFSS Design) working environment, as well as mathematical modeling using the Green tensor function method. At the same time, the obtained mathematical relations can be used in the future to solve the problem of finding the optimal size and position of a metal element in the sphere of LL.

The article deals with the issues of improving the quality of information using ultrasound, as well as existing analog and digital methods of its processing. The characteristics of signal filtering are analyzed depending on the signal-to-noise ratio. A number of modern applications in medical diagnostics are subject of high requirements for accuracy, noise immunity, reliability, continuity of operation and other quality indicators with a high dynamics of changes in non-stationary signals characterizing the functional state of the human body. On this basis, an algorithm and a device capable of extracting the informative components of noisy non-stationary signals are developed. In this paper, an algorithm of processing non-stationary signals of an ultrasonic transceiver is proposed. At the same time, three modules are developed and manufactured: 1) ultrasonic receiver module; 2) ultrasonic noise transmitter module (AM modulation); 3) an ultrasonic signal transmitter module (AM modulation) and an information processing algorithm based on a wavelet-forming function (wavelet threshold) consisting of the Coiflets 5 basis using a heuristically determined threshold value of the wavelet expansion coefficients. In this paper, the wavelet decomposition is carried out up to the 4th level. Based on the analysis of the obtained data, it was concluded that the second decomposition level is the most optimal for filtering non-stationary signals. As the decomposition level increases, the output signal-to-noise ratio decreases, and at the level N = 4, the output signal-to-noise ratio almost does not exceed the input one, therefore, filtering becomes inefficient. As a result of the synthesis of effective parameters of filtering electrocardiosignals, it is found that the maximum degree of signal processing from noise occurs using the Coiflets 5 wavelet using a heuristically determined threshold value. Experimental research is carried out in the training and production laboratory of electronics (FabLab), FSAEI HE “South Ural State University (National Research University)”.

Abstract Ataxia is defined as a lack of coordination of voluntary movement, caused by a variety of factors. Ataxia can be classified by the age at onset and type (chronic or acute). The causative lesions involve the cerebellum and cerebellar connections. The correct, appropriate use of neuroimaging, particularly magnetic resonance imaging, can make the diagnosis relatively accurate and facilitate implementation of the appropriate clinical management. The purpose of this pictorial essay is to describe the imaging findings of ataxia, based on cases obtained from the archives of a tertiary care hospital, with a review of the most important findings. We also review and discuss the imaging aspects of infectious, toxic, vascular, and inflammatory diseases.

RESUMO Objetivo: descrever e medir o Ângulo Pubo Bicrista Iliaca (APBCI) como novo parâmetro antropométrico. Correlacionar a medida com portadores de hérnia incisional gigante (HIG), da linha média da parede anterior do abdome (PAA). Métodos: medida do APBCI, através de reconstrução 3D a partir de tomografia computadorizada (TC). Realização de medidas por dois observadores, R e C, em 246 mulheres e 60 homens, adultos normais, afim de obter a medida do APBCI e sua correlação em portadores de HIG da PAA. Resultados: após cálculos de amostra, a medida do APBCI nos homens: 92,5+6,3º a 93,8+6,7º; nas mulheres: 90+6,7º a 94,3+6,8º [p-valor 0,337(R)/0,628(C)]. A média de idade foi de 57,9+15,9 anos (22 a 91 anos). Gênero feminino 57+15,7 anos (22 a 91 anos) e o masculino 61,7+16,5 anos (23 a 89 anos) p=0,067. Quanto à distribuição das faixas de 5 em 5 graus, inexiste diferença na distribuição do ângulo [p-valor 0,455(R)/0,672(C)]. A correlação idade e o ângulo demonstrou que quanto maior a idade, maior o APBCI. Não houve variabilidade entre as medidas do ângulo: 0,97 (IC95% 0,97; 0,98). Nos homens com HIG, a média está entre 108,3+5,37º (102,92º a 113,67º), e nas mulheres 107,8+6,64 (101,16º a 114,44º). Conclusão: o estudo permitiu concluir que a HIG não é apenas um defeito da PAA isolado. Determina alterações esqueléticas, na medida que o APBCI sofre a influência quanto ao afastamento das cristas ilíacas.

RESUMO Objetivo: análise crítica da investigação diagnóstica de lesões em segmento cefálico de motociclistas vítimas de acidentes de tráfego. Método: estudo observacional prospectivo incluindo motociclistas adultos vítimas de trauma, sem intoxicação exógena, em um período de 12 meses. A tomografia de crânio (TC) foi indicada de acordo com uma modificação dos “critérios canadenses”. Os pacientes que não foram submetidos a TC de crânio tiveram acompanhamento telefônico por três meses. A presença de lesões foi correlacionada com as varáveis coletadas através dos testes Qui-quadrado, t de Student ou Fisher, considerando p<0,05 como significativo. Resultados: dos 208 inicialmente incluídos, 206 (99,0%) estavam usando capacete. Dezessete estavam com sinais de intoxicação exógena e foram excluídos, restando 191 para análise. Noventa pacientes (47,1%) realizaram TC e 12 (6,3%) apresentaram lesões craniencefálicas, que se associaram significativamente a Escala de Coma de Glasgow (ECG) <15 (52,3% vs. 2,8% - p<0,001) e alterações ao exame físico da região cefálica/neurológico (17,1% vs. zero - p<0,05). Quatro pacientes (2,1%) precisaram tratamento cirúrgico de lesões intracranianas. Nenhum dos pacientes admitidos com ECG 15, em uso de capacete e sem alterações no exame físico apresentou TC alterada. Conclusões: para pacientes admitidos com ECG 15, que utilizavam o capacete no acidente e não apresentavam quaisquer alterações no exame físico, a realização da TC de crânio não trouxe mudanças no atendimento ao paciente. .

Off-label use of azithromycin, hydroxychloroquine, and ivermectin (the “COVID kit”) has been suggested for COVID-19 treatment in Brazil without clinical or scientific evidence of efficacy. These drugs have known adverse drug reactions (ADR). This study aimed to analyze if the sales of drugs in the “COVID kit” are correlated to the reported number of ADR after the COVID-19 pandemic began. Data was obtained from the Brazilian Health Regulatory Agency (Anvisa) website on reported sales and ADRs for azithromycin, hydroxychloroquine, and ivermectin for all Brazilian states. The period from March 2019 to February 2020 (before the pandemic) was compared to that from March 2020 to February 2021 (during the pandemic). Trend adjustment was performed for time series data and cross-correlation analysis to investigate correlation between sales and ADR within the same month (lag 0) and in the following months (lag 1 and lag 2). Spearman’s correlation coefficient was used to assess the magnitude of the correlations. After the pandemic onset, sales of all investigated drugs increased significantly (69.75% for azithromycin, 10,856,481.39% for hydroxychloroquine, and 12,291,129.32% for ivermectin). ADR levels of all medications but azithromycin were zero before the pandemic, but increased after its onset. Cross-correlation analysis was significant in lag 1 for all drugs nationwide. Spearman’s correlation was moderate for azithromycin and hydroxychloroquine but absent for ivermectin. Data must be interpreted cautiously since no active search for ADR was performed. Our results show that the increased and indiscriminate use of ”COVID kit“ during the pandemic correlates to an increased occurrence of ADRs.

This study aims to describe the mean height of adolescents from the five regions of Brazil and to evaluate socioeconomic and nutritional factors associated with normal growth. This is a cross-sectional study conducted in the Brazilian urban and rural areas with students aged 12 to 17 years (n = 71,553). Anthropometry, socioeconomic variables, physical activity, and diet were evaluated. Height-for-age z-scores were calculated and multiple linear regression models were used to investigate the association of exposure variables with height (outcome) by sex and age (12-13, 14-15, and 16-17 years). We observed a lower mean height in adolescents from the North Region and in individuals with low socioeconomic status. At 17 years of age, the closest to the final height in this sample, mean heights for girls and boys were 160.9 ± 0.1cm and 173.7 ± 0.3cm, respectively. In multiple linear regression analysis, physical activity (girls β = 0.119, 95%CI: 0.035; 0.202; boys β = 0.092, 95%CI: 0.012; 0.172) and high level of maternal education (girls β = 0.103, 95%CI: 0.001; 0.204; boys β = 0.39, 95%CI: 0.245; 0.534) were positively associated with height-for-age z-score in 16- to 17-year-old boys and girls. Other factors positively associated with height-for-age z-score in older students include higher protein consumption (β = 0.022, 95%CI: 0.010; 0.035) and obesity (β = 0.217, 95%CI: 0.084; 0.350) for boys, and low weight (β = 0.205, 95%CI: 0.028, 0.382) for girls. We observed differences in the mean height among adolescents from the five Brazilian regions. Normal growth, especially among older adolescents, was associated with high maternal education, practice of physical activity, protein consumption, and body mass index (BMI) categories.

Published: July 2022

O objetivo foi analisar a contribuição da indústria farmacêutica na sustentabilidade do Sistema Único de Saúde (SUS), a partir da pressão pela incorporação de medicamentos. Para tanto, foi realizado estudo descritivo das solicitações de incorporação de medicamentos enviadas à Comissão Nacional de Incorporação de Tecnologias no SUS (CONITEC) entre 2012 e 2020. Foram analisadas características como a indicação da tecnologia, avaliação econômica, componente de financiamento, consulta pública e decisão da CONITEC. Os resultados foram comparados segundo o tipo de demandante por teste estatístico. Foram analisadas 514 solicitações, sendo 438 referentes à incorporação. A indústria farmacêutica foi responsável por 37% das solicitações e 33,5% das incorporações. Foram observadas diferenças entre os demandantes quanto ao tipo de avaliação econômica e ao valor de razão custo-utilidade incremental, com metade das demandas da indústria acima do limiar de 3 PIB per capita/QALY. A indústria farmacêutica obteve mais contribuições nas consultas públicas de suas solicitações e apresentou concentração das solicitações em agentes antineoplásicos e imunomoduladores e em anti-infecciosos, sobretudo, para hepatite C e HIV. Também notou-se menor quantidade de demandas da indústria farmacêutica nos Componentes Básico e Estratégico da Assistência Farmacêutica. Os achados apontam o tensionamento entre a expressiva participação da indústria como solicitante, alta mobilização em consultas públicas e ênfase em medicamentos do Componente Especializado e a resistência da CONITEC a essa pressão, com tendência de maior recusa e maior participação de outros solicitantes nos pedidos de ampliação de uso, exclusão e incorporação de medicamentos menos requisitados pela indústria farmacêutica.

Este trabalho objetiva analisar a (in)segurança alimentar domiciliar sob o olhar da interseccionalidade. Para isso, foram analisados 14.713 domicílios, utilizando-se um questionário estruturado e a Escala Brasileira de Insegurança Alimentar, além dos dados do estudo transversal Qualidade do Ambiente Urbano de Salvador - QUALISalvador, realizado entre 2018 e 2020 em Salvador, Bahia, Brasil. A variável desfecho foi a situação de segurança alimentar (insegurança alimentar leve, moderada ou grave) e a variável exposição de interesse foi o cruzamento de raça/cor e sexo autodeclarado (homem branco, mulher branca, homem negro, mulher negra). Modelos de regressão logística multinominal foram usados para estimar a associação entre a exposição de interesse e o desfecho, ajustada a partir de questões socioeconômicas estratificadas segundo escolaridade e renda familiar per capita. Diante disso, concluiu-se que domicílios chefiados por mulheres negras apresentaram maior chance de insegurança alimentar leve (OR = 1,39; IC95%: 1,15-1,68; p = 0,001) e moderada ou grave (OR = 1,94; IC95%: 1,49-2,52; p < 0,001) em relação aos domicílios chefiados por homens brancos, além de maior chance de insegurança alimentar moderada ou grave em todos os níveis de escolaridade e nas faixas de até 1/2 salário mínimo e > 1 salário mínimo. Quando os responsáveis foram homens negros, a maior chance se apresentou na faixa > 1 salário mínimo. A insegurança alimentar nos domicílios chefiados por mulheres negras, mesmo em condições socioeconomicamente favoráveis, revela-se como uma das consequências da interação estrutural do racismo e do sexismo.
