Reinforcement potential of bleached sawdust kraft pulp in different mechanical pulp furnishes
Authors: Korpinen Risto I. , Fardim Pedro E.
Published: July 2023

Bleached unrefined and refined sawdust kraft pulps were added to bleached Norway spruce thermomechanical (TMP) and pressurised groundwood (PWG) pulps in different proportions. Handsheets were prepared and tested for physical properties. In addition, economic calculations were done to estimate the production costs of different bleached pulps in Finland. It was found that the addition of unrefined and refined sawdust kraft pulp improved drainability of the mechanical pulps. Tear strength of PGW furnishes was increased when either unrefined or refined sawdust pulp was added. Tear strength of TMP furnishes was not influenced when different sawdust kraft pulps were added. Up to 30 % of unrefined sawdust kraft pulp could be added and no significant negative effect was observed in TMP and PGW furnishes. On the other hand, when refined sawdust kraft pulp was added into the mechanical pulp furnishes, a clear improvement in the tensile strength was observed. According to the economic calculation the production cost of bleached sawdust kraft pulp is almost as low as the production cost of bleached mechanical pulp. We suggest that economically viable sawdust kraft pulp can be used as a substituent for expensive long fibre reinforcement kraft pulp in the production of mechanical pulp based papers.

Published: July 2023

A study was conducted to investigate the hydrolysis of cellulose-enriched corncob residue, a cellulosic waste from the xylo-oligosaccharides industry, by two processes. The corncob residue was hydrolyzed by cellulases via direct hydrolysis and two-step hydrolysis. Cellulases were produced by Trichoderma reesei RutC-30 with kraft pulp as the substrate. When the cellulase dosage was above 8 FPU•g-1 of corncob residue and the corncob residue concentration was 3%, over 90% hydrolysis yield and 49.99% glucose yield were obtained at 48 h. To enhance the hydrolysis yield of corncob residue, a new process coupling enzymatic hydrolysis, separation, and acid treatment was investigated. The corncob residue was first hydrolyzed using cellulase for 24 h. Then the remaining solids of corncob residue was separated from the liquid containing soluble oligosaccharides, and allowed to subsequently hydrolyze, using the adsorbed enzyme for 24 h. Using this method, the total hydrolysis yield was up to 97.60%, which represents an increase by 7.5% in comparison to the direct 48 h enzymatic hydrolysis. When the hydrolysates of the two-step enzymatic process were subjected to the concentrated acid hydrolysis at 110 ºC for 2 h, the glucose yield could be increased from 43% to 90%.

Published: July 2023

The cellulase production by P. janthinellum mutants on lignocellulosic material such as cellulose or steam exploded bagasse (SEB) in combination with wheat bran was studied in solid state fermentation (SSF). One of the mutants, EU2D21, produced the highest levels of endoglucanase (3710 IU g-1 carbon source) and β-glucosidase (155 IU g-1 carbon source). Ionic liquids are so-called green solvents that have become attractive for biocatalysis. Stability of mutant cellulases was tested in 10-50% of the ionic liquid 1-butyl-3-methylimidazolium chloride ([bmim]Cl). FPA and CMCase were significantly stable in 10% ionic liquid after 5h. β-glucosidase showed 85% of its original activity after 5 h incubation in 30% ionic liquid and retained 55% of its activity after 24 h. This enzyme preparation hydrolyzed ionic-liquid-treated SEB completely in 15 h in the presence of 20% ionic liquid. These studies revealed that there is no need of regenerating cellulose after ionic liquid treatment, since cellulase of mutant strain was found to be significantly stable in the ionic liquid.

Published: July 2023

The paper examines the impact of COVID-19 pandemic on operational effectiveness of parcel delivery sector companies operating in Lithuania. As demand of parcel delivery sector‘s services has increased, it is important to find out whether the impact of COVID-19 pandemic on operational effectiveness could be considered as positive even though the sector faces difficulties related to parcel delivery. The aim of the research is to evaluate the efficiency of parcel delivery sector companies operating in Lithuania during the COVID-19 pandemic. After the literature analyses, it was decided to examine the financial statements of 27 parcel delivery companies during the COVID-19 pandemic (2020-2021) and before the pandemic (2017-2019). During the investigation the impact of pandemic was analysed using the methods of correlation, regression, and logistics analysis. The main purpose of correlation analysis was to find connections between variables and by regression analysis to find causality between dependent and independent variables. The results of pandemic ware compared with results of pre-pandemic. After this, the results of pandemic have been applied in logistics analysis in forecasting process. Overall, it became clear that during the pandemic operational profit was more effective and costs were less effective comparing with results of pre-pandemic. In addition, the results of logistics analysis showed that there is a possibility that in the future operation profit will be ineffective and costs will be effective.
3D modeling of bolus for producing by prototyping and use in radiation therapy

Published: July 2023

Due to its vast number of occurrences, cancer has caused an economic impact on the public and supplementary health care sectors. It is estimated that more than 50% of patients diagnosed with malignant neoplasms need radiotherapy at some stage of their treatment, most of them treated with photon and/or electron beams. Due to the build-up effect (increase in dose in the matter from deposition on the surface to a point of maximum dose) caused by the interaction of photon beams with the irradiated tissue, bolus is often used in routine radiotherapy sectors to superficialize the point of maximum dose in the treatment region. The human body has complex surfaces that are often treatment regions in radiotherapy, but commercial bolus with a standard shape and length do not adapt perfectly to these surfaces. When this happens, air gaps may appear in the region, causing differences between the dose defined in radiotherapy planning and the dose delivered during treatment. In order to eliminate these air gaps and possible dose distribution errors, two methodologies for individualized bolus construction were proposed. In both cases, computed tomography images of the Alderson Rando male anthropomorphic phantom were used as a reference of the anatomy of a human body. From these images, one bolus model was constructed in the 3D modeling software 3ds Max by creating a polygonal mesh, while the other bolus model was constructed in the image computing software 3D Slicer, using segmentation tools. The software Creality Slicer 1.2.3. prepared the files for 3D printing. The prints of the files were made on polylactic acid filament on the Tevo Tarantula Pro printer. The bolus construction methodology using the software 3ds Max showed better results, as a greater contact area between the bolus and the phantom was observed when testing the fit of the printed bolus to the physical phantom. The 3D files of the virtual bolus will be available for future computer simulations. The printed bolus could be used in dosimetry with linear accelerators.
Influence of FDI on structural changes in the economy in the context of prospects for post-war recovery of Ukraine
Authors:   State Institution “Institute for Economics and Forecasting, NAS of Ukraine”, Shovkun Inna
Published: July 2023

The recovery of the national economy, which is undergoing great destruction as a result of full-scale Russian aggression in Ukraine, will require attracting not only domestic but also foreign investments. The post-war experience of various countries shows that the inflow of foreign capital contributed to meeting the needs for investment resources for the reconstruction of the economy and its structural modernization. The recent history of the rapid rise of newly industrialized countries also demonstrates that foreign investments enable the transformation of the structure of the host economy, and its progress towards higher levels of industrial development. The purpose of this study is to conduct an analysis of the accumulation and sectoral distribution of FDI in the Ukrainian economy, to assess the effects of FDI to change the structure and dynamics of economic growth, and to identify approaches to attracting foreign investment in the context of prospects for post-war recovery and economic restructuring. The article examines the accumulation of FDI in the Ukrainian economy in historical retrospect, analyzes the distribution of their reserves among the sectors and subsectors, as well as their geographical origin. The author assesses the depth of penetration of the FDI into the economy in general and into the technological sectors within the processing industry, in particular, and reveals various contradictory effects created by foreign investments for the development of the national economy, technological progress, and economic security. Using regression modeling, the article investigates the FDI as a factor capable of contributing to the transformation of Ukraine’s economy, and changing the structural distribution of added value and employment between sectors. The simulation results confirm that the accumulation of FDI really affects the dynamics of GVA production and employment in economic sectors, that is, it causes structural shifts in the economy. At the same time, sectoral assessments reveal the mixed effectiveness of this factor in terms of the strength and direction of changes in the structure of the economy.

Published: July 2023

OBJECTIVES

For patients hospitalized with bronchiolitis, many hospitals have implemented clinical practice guidelines to decrease variability in care. Our hospital updated its bronchiolitis clinical pathway by lowering goal oxygen saturation from 90% to 88%. We compared clinical outcomes before and after this change within the context of the pathway update.

METHODS

This was a retrospective analysis of patients <24 months old admitted to a pediatric tertiary care center from 2019 to 2021 with bronchiolitis. Patients with congenital heart disease, asthma, home oxygen, or admitted to an ICU were excluded. The data were stratified for patients admitted before and after the clinical pathway update. Statistical methods consisted of 2 group comparisons using the χ-square test for categorical variables, the Wilcoxon rank-sum test for continuous variables, and multiple regression analysis.

RESULTS

A total of 1386 patients were included, 779 preupdate and 607 postupdate. There was no statistically significant difference in the admission rate of patients presenting to the emergency department with bronchiolitis between the 2 groups (P value .60). The median time to room air was 40.0 hours preupdate versus 30.0 hours postupdate (P value < .001). The median length of stay was 48.0 hours preupdate versus 41.0 hours postupdate (P value < .001). Readmission rate was 2.7% within 7 days of discharge preupdate, and 2.1% postupdate (P value .51).

CONCLUSIONS

Decreasing goal oxygen saturation to 88% was associated with a statistically significant decrease in time spent on oxygen and length of stay for patients admitted with bronchiolitis with no increase in readmissions.

Aortic dissection is often a fatal condition if not recognized and treated emergently. Fortunately, it is extremely rare in children and adolescents. We report a case of an adolescent boy who survived an aortic dissection due to severe aortic root dilation. A comprehensive history and physical examination, including family history, can facilitate an early diagnosis of connective tissue diseases, such as Loeys-Dietz syndrome (LDS).
The Narrative Properties of the 19th-Century Verse Novel
Authors: Bacskai-Atkari Julia
Published: July 2023

This book investigates the narrative properties of the 19th-century verse novel. The genre grew out of Lord Byron’s Don Juan and established itself in various European literatures, with famous examples such as Pushkin’s Eugene Onegin. The proposed analysis is unique in the existing literature in defining the genre based on formal properties and in examining its exceptional, reflexive structure in detail. Apart from 19th-century texts, verse novels from contemporary literature are also includ-ed, and thus the connection between these two contexts is discussed for the first time extensively.

Authors: Vakaliuk T. A. , Andreiev O. V. , Dubyna O. F. , Nikitchuk T. M. , Puleko I. V.
Published: July 2023

Context is due to the need to analyze the electromagnetic accessibility of terrestrial radio radiation sources at long distances, which is typical for the operation of a spacecraft of radio technical intelligence with a passive synthesis of the antenna aperture.

Objective is to calculate the probability indicators of detecting the fact of signal emission of ground-based radar stations using radio-technical intelligence installed on a space carrier.

Method. Analytical calculation of the correct detection probability of the signal of the radio radiation sources by the spacecraft of radio technical intelligence based on the determination of the signal-to-noise ratio at the input of the detection device. The analysis of the technical characteristics of the group of ground radars made it possible to calculate the probability of correct detection only for the virtual radar, which generates the minimum number of pulses with the minimum energy during reconnaissance among all the analyzed radars.

Results. The fulfillment of the conditions of electromagnetic accessibility is checked and the correct detection probability of the signals of modern radar stations by the space radio-technical intelligence system with a passive synthesis of the antenna aperture was calculated.

Conclusion. Proposed use of the correct detection probability of the signal as the resulting indicator of electromagnetic accessibility of the radio radiation source. In the example radar stations of the air defense proved, that the proposed parameters of the space radio technical intelligence system with a passive synthesis of the antenna aperture provide the values of the correct detection probability of the signal, which are quite acceptable for modern monitoring systems.
Educazione e formazione: l’approccio, le sfide e la risposta audace di Edmund Bojanowski. Education and Training: Edmund Bojanowski’s Approach, Challenges and Bold Response

Edmund Bojanowski, an esteemed Polish pedagogue who lived in the XIX century, dedicated his life to the creation of education services for small children in his country, (which he called Ochronki (= protection), and to the training of the women instructors (Ochroniarki = the protectors). His objective was a preschool education inspired by Catholic values, as man was created “in the image and likeness of God”; he envisioned a system that would raise good citizens and good Christians, enabling them to tackle the challenges of life. Blessed with a strong educational vocation, he put great effort in preparing the women instructors for this task, providing them with both pedagogic knowledge and rigorous moral principles, as well as promoting critical thinking and sense of responsibility, with the authority borne of love for the true good. He strived to promote these abilities in his instructors, so that they would transfer them to the children; he felt these qualities transform knowledge into life wisdom, and allow a person to live with dignity and respect for oneself and others. These core beliefs were also the basis for the creation of a religious order of nuns.

Authors:   Korea Association for International Commerce and Information, Park Hyeon-Jung , Lim Jae-Wook , Lee Keon-Bong
Published: July 2023

This study aims to investigate how and why information integration and formalization directly affect product advantages. This study adopted a contingency perspective to examine the relationships between two variables(information integration and formalization) and product advantage. To verify the validity of the research framework, it was empirically tested by a Korean sample. The hypotheses were tested using a mediated hierarchical regression analysis. By examining the mediating effects of knowledge sharing and technological learning on the relationships between two variables(information integration and formalization) and product advantage, the results show that the impact of information integration on product advantages is attributed to knowledge sharing and technological learning (complete mediation). In addition, the research also shows that the impact of formalization on product advantages is attributed to knowledge sharing and technological learning (partial mediation).
Philosophy and Intercultural Communication: The Phenomenon of a Human Being in the Confucian Tradition
Authors: Danylova T. V.
Published: July 2023

Purpose. This paper aims to investigate the phenomenon of a human being within the Confucian tradition as well as its interpretations from intercultural perspective. Theoretical basis. One of the ways to understand the deepest level of the intercultural dialogue is to reveal the interpretations of a human being in philosophical traditions, since they refer to the formation of personality and identity within a given culture including interpersonal, intergroup, and intercultural relations. Humanism based on the unity of Human and Heaven runs like a red thread through the philosophical teachings of Confucius, Mencius, Xunzi, Zhu Xi, Wang Yangming defining the ideas of human nature, his/her duties, his/her place and roles in society that shaped the Chinese mentality. Originality. Quite often, Chinese concepts (for example, human dignity beyond the ideas of democracy and mass political participation, guanxi, mianzi) are incomprehensible to the representatives of the Western civilization, which leads to the challenges in intercultural communication. The interpretation of these ideas in the context of Confucianism allows to understand them from the perspective of Others and expand the set of patterns of cultural perception. This ultimately leads to the awareness that there are many social, political, cultural realities, which we perceive through the lens of our own concepts and attitudes. The participants of an intercultural dialogue realize that each of them has a unique experience, own way of posing a problem and resolving it, and no one is better or worse. Conclusions. Confucian philosophy shaped the worldview of Chinese people, defined values, goals, meanings, attitudes, communication models, which affected all spheres of Chinese life and culture. The study of the philosophical heritage of the great Chinese civilization enhances the cultural competence of the intercultural communicators and expands the field of dialogue to the level of global communication.

Published: July 2023

The work on the draft bill started at the beginning of 2002 by the project of the National and Ethnic Minority Committee of the Sejm. During the first reading the deputies of the Law and Justice and the Polish Families League made a proposal to reject the draft. After the rejection of this proposal, the further work was carried out mainly in the extraordinary subcommittee, which prepared a report in spring 2004.The final work on the Act took place in National and Ethnic Minority Committee. During the third reading in the Sejm, also other motions to reject the draft or to limit its scope were proposed. These proposals came from right-wing and Catholic-national parties. In the Act in comparison to the original project there were extended rules on the use of minority language as an auxiliary, as well as for the use of this language as additional for assigning the names to towns and villages. A new solution was to introduce the notion of a regional language and giving this status to the Kashubian language. Also a solid base for the contacts of the government with national and ethnic minorities was established.
Programy wyspecjalizowane jako zadanie w realizacji misji publicznej nadawcy publicznego

The remit of public service broadcasting includes the obligation of universal programming, which covers all kinds of programmes such as culture, news, entertainment and sport. Several European Union documents stress the special role of Public Service Broadcasting (PSB) in society and acknowledge a far-reaching autonomy of Member States to define and finance their national system of public service broadcasting. All European countries have defined remits for their public service broadcasters. The definition of the mission of PSB in Poland is only related to the activity of the public radio and television. Also the way PSB gives account for its programme activities, and the control of the way PSB fulfils its remit. Theme channels are part of the remit of public service broadcasting. These channels are considered as important and almost self-evident activities of PSB. Nevertheless there is a need for such provisions to define the mission of PSB in Poland. This is necessary to further specify the criteria used to determine whether a service of theme channels which are transmitted by the public television is of an economic or a non-economic nature. This is the most important because of the requirements of state financing of public service broadcasters. These transparency requirements are internal accounts corresponding to different activities – public service and non-public service activities must be separated.
Zakaz cenzury prewencyjnej w świetle zasady wolności słowa
Authors:   Uniwersytet Warszawski, Jaworski Lech
Published: July 2023

Censorship is a special case of media control. In the authoritarian system it is preventive censorship as well as press licensing that constitute a characteristic symptom of this control. In law, the notion of censorship has not been defined: therefore one has to refer to doctrines and jurisdiction. In the Polish law, a clear ban on preventive censorship, understood as making publishing or broadcasting a certain message dependent on the prior consent of a public authority, was included in Article 54 Section 2 of the Constitution. This regulation constitutes, in the area that it regulates, a development and confirmation of the freedom of the press and other media rule expressed in Article 14 of the Constitution. Additional provisions of the press’s freedom of speech in the context discussed here are formulated in Article 3 of the Press Law. Although it does not refer directly to preventive censorship, the ban it expresses is supposed to prevent the actual infringement on the freedom of the press by preventing its print and distribution. As for the issues discussed here, what may be controversial is the approach limiting the introduction of preventive censorship only to public administration institutions. The Constitutional Tribunal in its verdict from 20 July 2011, referring to the use of publication ban within proceedings to secure claims in claims against mass media concerning the protection of personal rights (Article 755 Paragraph 2 of the Code of Civil Procedure) stated that the judicial power is not the administrative power. Therefore, the courts’ activity cannot be considered as using censorship, but rather as monitoring the law being obeyed in the preventive meaning. And as for the regulations included in the European Convention on Human Rights, its Article 10 (as well as its other regulations) does not directly refer to the issue of controlling or obstructing publications, especially press releases. This question, however, has been the subject of many rulings of the European Court of Human Rights.

Abstract The aim of this research was to analyze pregnancy incidence and associated factors in a cohort of 753 women living with HIV/AIDS (WLWHA) in Rio de Janeiro, Brazil, from 1996 to 2016. Women aged 18-49 years who were not on menopause (surgical or natural) and did not have a tubal ligation were eligible for the study. Data were collected by medical professionals during initial and follow-up visits. Person-time pregnancy incidence rates were calculated throughout the follow-up period. Pregnancy incidence-associated factors were investigated by univariate and multiple analyzes, using an extension of the Cox survival model. Follow-up visits recorded 194 pregnancies, with an incidence rate of 4.01/100 person-years (95% CI: 3.47; 4.60). A higher pregnancy incidence was associated with CD4 nadir ≥ 350 cells/mm³, use of an antiretroviral regimen not containing Efavirenz, and prior teenage pregnancy. In turn, women with a viral load ≥ 50 copies/mL, age ≥ 35 years old, with two or more children and using a highly effective contraceptive method showed a lower incidence. Results showed a significant reduction in pregnancy incidence after 2006, a significant reduction in female sterilization from 1996 to 2016, and a high rate of cesarean sections. The association found between pregnancy incidence and the use of contraceptive methods and virological control markers suggests a good integration between HIV/AIDS and reproductive health services. The high rate of cesarean section delivery indicates the need to improve childbirth care.

Germination on the nutritional properties of seeds of four melon varieties
Authors: Araújo Karoline Thays Andrade , Queiroz Alexandre José de Melo , Figueirêdo Rossana Maria Feitosa de
Published: July 2023

ABSTRACT: Fruit seeds, in terms of nutrition, are as wholesome as the grains cultivated exclusively for human consumption. The fruit pulp-processing agroindustry, more often than not, discards these seeds as unprofitable waste. The inclusion of seeds as a consumer product, equal in value to the pulp itself, can be made possible by adopting processes that increase their worth, and ideally at minimal costs. The controlled germination process is suitable for such an endeavor. The strategy presented here, is low in cost and permits the modulation of the constituents of the seeds by breaking the continuity of the process at the precise time, thus enabling the formation of a new product, which possesses bioactive properties. This research was performed with the focus on exploring the ways that the germination time influences the constituents of the seeds in four melon varieties. The Cantaloupe, Gália, Pele-de-Sapo and Orange melon seeds were studied and the water content, ash, proteins, lipids, total and reducing sugars, total phenolic compounds, tannins, flavonoids and anthocyanins were determined in the samples. This was done in natura and post germination specifically at 24, 48, 72 and 96 hours. Germination altered all the parameters, except the ash content. In Pele-de-Sapo, the protein content dropped, while in the others it showed an increase. Germination caused a rise in the values of the total and reducing sugars, as well as the total phenolic compounds, tannins, flavonoids and anthocyanins, showing variations during the intermediate times, based on the variety. Mostly, higher values were achieved at 96 h of the germination process.

Methods: Retrospective study based on medical records of patient with STS treated by the Orthopedic Oncology Group at the Santa Casa de São Paulo, from 2006 to 2019. Data from 121 patients were analyzed according to age, sex, histological type, tumor location, treatment, previous surgery in a non-specialized service, local recurrences, lung metastases, and survival analysis. Results: The most frequent location was the thigh. Patients who underwent surgery with a non-specialized group had higher rates of local recurrence and those with pulmonary metastasis had a lower survival rate. Conclusion: STS can occur at any age and the prevalence of the histological type depends on the patients’ age group. Level of Evidence II, Prognostic Study.

ABSTRACT Objective: To perform an immunohistochemical evaluation using the IDH1 and Ki67 markers in patients who underwent treatment for chondrosarcoma in a reference service center in Brazil. Methods: Retrospective analytical observational study using medical records of patients diagnosed with chondrosarcoma. Besides the epidemiological and clinical profile, important variables for prognosis and correlation with immunohistochemical analysis results with Ki67 and IDH1 markers were evaluated. Results: Histopathological examinations by immunohistochemistry of 56 patients were analyzed, 52% of which were women, with the age group 20-60 years being more prevalent. Grade 1 and 2 histological subtypes corresponded to most chondrosarcomas. The femur, humerus, and tibia were the most frequent anatomical sites. Most tumors (59%) were larger than 8 cm. Ki67 expression was very low (< 10%) in 98% of patients. The analysis of IDH1 was positive in 43% of the cases. The correlation between IDH1 positivity and tumor size was statistically significant, but regarding survival, we observed no significance. Conclusion: Immunohistochemical analysis using IDH1 and Ki67 markers in patients with conventional chondrosarcoma is not useful for prognostic guidance.

Published: July 2023

Abstract Objectives: to estimate the intention of breastfeeding (IBF) duration and its association with sociodemographic, obstetric characteristics and experience with breastfeeding among pregnant women undergoing prenatal care. Methods: cross-sectional study, with pregnant women undergoing prenatal care in public health services in Colombo, Paraná, Brazil. The duration of IBF was questioned to pregnant women. Negative binomial Poisson regression with robust variance adjustment allowed estimating crude and adjusted prevalence ratios (PR), and 95% confidence intervals (CI95%) of the association between IBF duration and exposure variables. Results: among the participating pregnant women (n = 604), 7.9% reported having IBF for less than six months, 28.0% from six to 11 months, 38.3% from 12 to 23 and 25.9% for 24 months or more. The mean IBF time was 13.5 ± 8.4 and median of 12 months. Pregnant women with moderate food insecurity (PR=1.34; CI95%=1.04-1.73), multiparous women (PR=1.13; CI95%=1.00-1.26), and who reported having been breastfed as babies (PR=1.19; CI95%=1.02-1.40) had a longer IBF time. Conclusions: food security situation, primiparity and exposure to breastfeeding in childhood are determinants of IBF during pregnancy.

Abstract Objectives: to evaluate the reliability of information available on popular websites, in other words, websites aimed lay pregnant women, about absolute and relative indications for cesarean sections. Methods: this was a descriptive/comparative study based on the popular websites most likely to be visited by lay pregnant women and that contained information about indications for absolute and relative cesarean sections. Cohen’s Kappa index of agreement was used to analyze the reliability degree on the indications for cesarean sections presented on the websites and the scientific evidence. Results: there was a higher prevalence (62.63%) of information on the indications for cesarean sections that did not mention whether the indication was absolute or relative, and of these indications, 40.74% were not indications for cesarean sections. Low agreement was also observed among websites and the scientific evidence when the website mentioned the indication for cesarean section was absolute or relative. Conclusion: this study showed that the reliability of the information on absolute and relative indications for cesarean sections available in popular websites is questionable.

Resumo Objetivos: analisar a correlação entre autoeficácia materna e apoio social de mães de recémnascidos prematuros no período de pós-parto precoce. Métodos: estudo transversal, realizado junto a 120 mães de prematuros de uma Maternidade Escola, no período de junho a dezembro de 2018. Utilizaram-se dados sociodemográficos, reprodutivos e escalas para Avaliação da Autoeficácia Materna e Apoio Social. Procedeu-se a análise descritiva e aplicaram-se os testes de Teste Mann-Whitney, Teste de Kruskal Wallis e correlação de Spearman. Resultados: evidenciou-se correlação positiva entre autoeficácia, paridade (p=0,017), anos de estudo (p=0,017) e Apoio Social (p=0,002). Um achado inesperado foi a alta autoeficácia entre mães com até oito anos de estudo, do interior do estado e de baixa renda. Conclusão: o apoio social, em todas as dimensões: material, afetivo, emocional, de informação e interação social, mostrou-se preditor da autoeficácia materna.

Abstract Objectives: to analyze a correlation between self-efficacy and social support of mothers of preterms in early postpartum. Methods: cross-sectional study, carried out with 120 mothers of preterm infants from a Maternity School, from June to September 2018. Sociodemographic, reproductive and scales were used to assess the Maternal Self-Efficacy and Social Support. A descriptive analysis was carried out and the MannWhitney Test, Kruskal Wallis Test and Spearman correlation were applied. Results: there was a positive correlation between self-efficacy, parity (p=0.017), years of schooling (p=0.017) and Social Support (p=0.002). An unexpected finding was a high self-efficacy among mothers up to eight years of schooling, in the countryside of the State and with low income. Conclusion: social support, in all dimensions: material, affective, emotional, information and social interaction, proven to be a predictor of maternal self-efficacy.

Resumo Objetivos: analisar o consumo de alimentos ultraprocessados e sua associação com imagem corporal, atividade física, estado nutricional e autoavaliação alimentar de gestantes cadastradas na Atenção Primária à Saúde. Métodos: trata-se de um estudo transversal, realizado com gestantes cadastradas na Estratégia Saúde da Família do município de Montes Claros, Minas Gerais. Os dados foram coletados por meio de um questionário. A variável dependente foi consumo de alimentos ultraprocessados, e as independentes abordaram aspecto corporal, atividade física, estado nutricional, autoavaliação alimentar e consumo alimentar. Realizou-se análise descritiva e para análise de associação, utilizou-se o modelo de regressão linear com associações brutas e ajustadas. Resultados: participaram do estudo 1.185 gestantes. O consumo calórico proveniente dos ultraprocessados representou 32,0% da dieta diária dessas mulheres. Verificou-se associação entre consumo de ultraprocessados com atividade física (β=-0,08; p<0,01), estado nutricional pré-gestacional (β=-0,12; p<0,01) e imagem corporal (β=0,08; p=0,01). Conclusão: as gestantes apresentaram alto consumo de alimentos ultraprocessados. Ter imagem corporal negativa, menor nível de atividade física, estado nutricional pré-gestacional elevado são condições que influenciaram o consumo desses alimentos.

ABSTRACT Purpose To compare the swallowing alteration markers in patients with and without COVID-19 and to study the predictive variables of oral feeding contraindication in patients requiring prolonged orotracheal intubation. Methods Retrospective case-control study, with medical record data collection of clinical and demographic variables and the clinical evaluation of swallowing. The collected variables were statistically compared between patients with COVID-19 (SG) and without COVID-19 (CG). Robust Poisson regression analysis was used to evaluate the effect of COVID-19 and other variables on oral feeding contraindication. Results 351 patients were included, 269 in the SG and 82 in the CG. Patients in the SG were younger when compared to the CG (50.7 ± 12.8). The total time of orotracheal intubation was significantly longer in the SG. The patients in the SG had a higher prevalence of weak cough, dysphonia, worse degrees of dysphagia and higher occurrence of contraindication of oral feeding. In the bivariate analysis, it was found that patients with COVID-19 were 65% more likely to have oral feeding contraindication. However, when COVID-19 was adjusted with other clinical and demographic variables, it was found that these variables had a greater influence on the contraindication of the oral feeding than the COVID-19. Conclusion Prolonged orotracheal intubation had a worse effect on alteration markers in swallowing and reintroduction of the oral feeding in COVID-19 patients. Age over 60 years, orotracheal intubation time greater than 5 days, reintubation, and delirium were shown to be predictive of oral feeding contraindication in intubated patients.

RESUMO Objetivo comparar os marcadores de alteração na deglutição de pacientes com e sem COVID-19 e estudar as variáveis preditivas de contraindicação da alimentação por via oral em pacientes com necessidade de intubação orotraqueal prolongada. Métodos estudo caso-controle, retrospectivo, com coleta de prontuário de variáveis clínicas e demográficas e da avaliação clínica da deglutição. As variáveis coletadas foram comparadas estatisticamente entre pacientes com COVID-19 (grupo estudo -GE) e sem COVID-19 (grupo-controle - GC). A análise de regressão de robusta de Poisson foi utilizada para avaliar o efeito da COVID-19 e das demais variáveis na contraindicação da alimentação por via oral. Resultados foram incluídos 351 pacientes, 269 no GE e 82 no GC. Pacientes do GE apresentaram menor idade, quando comparados ao GC (50,7 ± 12,8). O tempo total de intubação orotraqueal foi significativamente maior no GE. Os pacientes do GE apresentaram maior prevalência de tosse fraca, disfonia, piores graus de disfagia e maior ocorrência de contraindicação da alimentação por via oral. Na análise bivariada, verificou-se que os pacientes com COVID-19 apresentaram 65% maior probabilidade dessa contraindicação. Entretanto, quando a COVID-19 foi ajustada com outras variáveis clínicas e demográficas, verificou-se que as estas apresentaram maior influência sobre a contraindicação de alimentação por via oral do que a COVID-19. Conclusão a intubação orotraqueal prolongada teve pior efeito nos marcadores de alteração na deglutição e na reintrodução da via oral de pacientes com COVID-19. A idade maior que 60 anos, tempo de intubação orotraqueal maior que cinco dias, reintubação e delirium demonstraram ser preditivas de contraindicação da alimentação por via oral em pacientes intubados.

ABSTRACT Objective: to estimate excess deaths during the COVID-19 pandemic in the state of Santa Catarina and its macro-regions, Brazil, 2020-2021. Methods: this was an ecological study, using data from the Mortality Information System; excess deaths in adults were calculated by the difference between the observed number of deaths and expected number of deaths, taking into account the average of deaths that occurred between 2015 and 2019; the variables “macro-region of residence”, “quarter”, “month”, “sex” and “age group” were analyzed; data were analyzed in a descriptive manner. Results: a total of 6,315 excess deaths in 2020 and 17,391 in 2021, mostly in males (57.4%) and those aged 60 years and older (74.0%); macro-regions and periods with the greatest excess deaths were those in which there were most deaths due to COVID-19; the greatest excess deaths occurred in March 2021 (n = 4,207), with a progressive decrease until the end of the year. Conclusion: there were excess deaths in the state of Santa Catarina and in all its macro-regions during the COVID-19 pandemic.
