Da civilização dos pampas à raça de gigantes: relações raciais e regionalismos na construção do gaúcho e do bandeirante na historiografia brasileira dos anos 1940
Authors: Silva Sarah Calvi Amaral 
Published: July 2024

Este artigo pretende abordar a elaboração de duas interpretações regionalizadas referentes à formação histórica e social brasileira, específicas ao Rio Grande do Sul e a São Paulo. Utilizando noções biológicas de raça, o autor sul-rio-grandense Emílio Fernandes de Souza Docca e o intelectual paulista Alfredo Ellis Junior proferiram comunicações no III Congresso Sul-Rio-Grandense de História e Geografia (1940) do IHGRS, buscando, entre outras preocupações, compreender a presença negra em seus estados de origem. Nesse sentido, ambos atentaram para as características fenotípicas e culturais atribuídas aos africanos desembarcados no país durante o período escravista, percebendo as consequências das “entradas” destes contingentes para a constituição dos tipos sociais definidos como o gaúcho e o bandeirante. As comunicações mencionadas serão por nós discutidas a partir de experiências intelectuais dos autores, inscritas num contexto de transformações políticas e “científicas” no Brasil.

Строение верхней части криолитозоны и рельеф северо-востока Западной Сибири обусловлены изменением природной обстановки в позднем неоплейстоцене и голоцене. В 2016–2021 гг. изучены разрезы отложений на разных элементах рельефа III озерно-аллювиальной равнины Пур-Тазовского междуречья – увалах и термокарстово-эрозионных ложбинах. В строении верхней части равнины выделены каргинско-сартанские аллювиальные, озерные, склоновые отложения и голоценовые торфяники. На основе стратиграфии и новых геохронологических данных на Пур-Тазовском междуречье выявлены последствия активизации неотектонических процессов в сартанский период и влияния климатических факторов на дифференциацию аккумулятивных и денудационных процессов в голоцене.
The structure of the upper part of permafrost and the topographic features in the northeast of Western Siberia were shaped by changes in the natural environment in the Late Pleistocene and Holocene. In 2016–2021, sections of different landforms – ridges and thermokarst-erosional hollows – were studied within the third lacustrine-alluvial plain of the Pur–Taz interfluve. The upper part of the plain includes the Kargin–Sartan alluvial, lacustrine, and slope sediments and Holocene peatlands. Based on the stratigraphy and new geochronological data on the Pur–Taz interfluve, the consequences of the activation of neotectonic processes in the Sartan period and the influence of climatic factors on the differentiation of accumulative and denudation processes in the Holocene were identified.
THERMODYNAMIC CALCULATION OF A HEAT PUMP COMBINED WITH A SURFACE FOUNDATION ON PERMAFROST SOILS
Authors: Горбунова А.А. 
Published: July 2024

Предлагаемый расчет учитывает особенности работы теплового насоса в составе поверхностного фундамента на многолетнемерзлых грунтах, которые заключаются в перетекании тепла из греющего контура теплового насоса в охлаждающий. Перетекание тепла снижает коэффициент преобразования низкопотенциального тепла в высокопотенциальное, однако в известных публикациях игнорируется. Расчет показывает также существенное влияние марки фреона в контуре “испарение–конденсация” холодильной машины на коэффициент преобразования.
The proposed calculation takes into account the peculiarities of the operation of the heat pump as part of the surface foundation on permafrost soils, i.e., the heat flow from the heating circuit of the pump to the cooling circuit. Heat transfer reduces the conversion coefficient of low-potential heat into high-potential heat, but, unfortunately, this is ignored in well-known publications. In addition, the calculation shows a significant effect of the freon brand in the evaporation–condensation circuit of the refrigeration machine on the conversion coefficient.

Published: July 2024

Background: The COVID-19 pandemic imposed a significant burden on healthcare systems in the Asia-Pacific region and has had a varying impact on physicians at different stages of their career. This study sought to evaluate the personal perspectives and the experiences of early and mid-career cardiologists and cardiothoracic surgeons with regard to the impact of the pandemic in the region. Methods: A cross-sectional web-based survey was conducted from June to July 2023 among members of the Asian Pacific Society of Cardiology (APSC) young community. The survey aimed to assess the impact of COVID-19 on cardiovascular clinical care and research activities that contained sections on demographic information, pandemic-related clinical and research experiences, personal stories, and interest in long-COVID research. Results: Overall, 60 physicians (44%) in the APSC young community responded to the survey. Cardiovascular disease patient numbers initially dropped in 2020 during the pandemic’s early stages but gradually increased in the following 3 years. Non-cardiovascular patient care workloads also rose during the first 2 years of the pandemic. Respondents observed notable changes in clinical care, research and personal life. Positive aspects included increased adaptability and telemedicine adoption, while challenges involved higher workloads and stress. More than 70% expressed interest in understanding the impact of long COVID, with Southeast Asian members showing the highest levels of interest. Conclusion: This survey conducted in the aftermath of the pandemic shed light on the challenges experienced by early to mid-career Asia-Pacific cardiovascular physicians. Physicians at this career stage encounter distinctive hurdles that require thoughtful consideration and effective solutions.

Published: July 2024

AbstractOur study aims to examine the perceptions of chefs and restaurants' management in Hungary regarding the importance of health and nutrition in menu planning in today's catering businesses. We assessed 190 complete responses from chefs/cooks and managers/owners of restaurants and catering businesses in Hungary between February 2021 and February 2022 via email on four aspects; health, nutrition, nutrition practice, and consumers' concerns. This study shows an overall improvement in chefs' and restaurants' management's nutritional knowledge compared with similar studies in the past. However, most chefs still believe that the customers ignore the nutrition and nutrient content of the meals when dining away from home. In addition, experienced chefs do not perceive that the preparation of low-fat foods requires additional work and that low fat-foods can taste great. This study found no significant differences related to nutrition in menu planning based on chefs' and managers' backgrounds (i.e., gender, age, position, educational level, work experience, and type and location of establishment).

AbstractThis study examined the production of kombucha beverages with several combination of black tea and Aloysia citrodora. For this purpose, five types of kombucha drinks were prepared using different ratios of pure black tea and pure A. citrodora (80:0, 50:30, 40:40, 30:50, and 0:80). Total phenolic and flavonoid content, radical-scavenging capacity based on DPPH, ferric reducing antioxidant power (FRAP) in the fermentation period (days 0, 5, 10, and 15), and cytotoxicity on the 15th day have been evaluated. The results showed that phenolic and flavonoid contents and antioxidant properties increased during fermentation (P < 0.01). Using A. citrodora as a substrate enhanced the phenolic and antioxidant properties. The maximum amounts of polyphenols and flavonoids were 240.24 mg GAE/mL and 49.65 μg QE/mL, respectively, and the DPPH value was 92.81% for the samples with an equal ratio of black tea and A. citrodora on the 15th day. In addition, this sample had the highest rate (66%) of destroying PC3 prostate cancer cells at a 600 μg dL−1 concentration. Using A. citrodora in kombucha drink not only improved the health indices but also caused better acceptance by the sensory evaluators compared to the sample of kombucha beverage produced with pure black tea.
A Conceptual Framewok of Academic Integrity in Islam
Authors: Akbar Akbar , Picard MIchelle 
Published: July 2024

Academic integrity is vital to maintain quality standards and prevent misconduct that undermines standards in higher education institutions, including in Islamic Higher Education (IRHE) Institutions. However, this concept has been stereotyped as a western concept because the literature of academic integrity has flourished in western universities over the past three decades. This study aims to investigate the relationship between Islam and the concept of academic integrity and provides evidence that academic integrity should not be regarded as merely a Western concept but is also conceptualized in Islam. This study was designed using grounded theory. Muslim scholars in three IRHE institutions in Indonesia were interviewed to find out how they conceptualized academic integrity in Islam. The data were analyzed using content analysis and themes emerged to develop a conceptual framework of academic integrity in Islam. The study found that academic integrity and religiosity is intertwined. This study brings a new understanding that religiosity and academic integrity is inseparable in IRHE.
Microsatellite instability as a reliable marker of coexisting endometrial cancer in atypical endometrial hyperplasia
Authors: Protasova А. E. , Raskin G. A. , Sobivchak M. S. 
Published: July 2024

Background. Endometrial cancer (EC) dominates in the structure of gynecological cancer morbidity. There has been an increase in this nosology in women of reproductive age. The morphological precancerous form of endometrioid adenocarcinoma is endometrial intraepithelial neoplasia (EIN), or atypical endometrial hyperplasia (AEH), that is difficult to diagnose: there is a high percentage of underdiagnosis resulting in a wrong treatment strategy. To improve the accuracy of diagnosis, additional immunohistochemical markers are being studied that are not part of the physician»s routine practice. Extremely promising for the prognosis of endometrial malignancy is the assessment of the functioning of the genes of the DNA mismatched nucleotide repair system (DNA mismatch repair system, MMR).Aim. To assess the diagnostic value of (microsatellite instability, MSI) in patients with AEH to rule out coexisting endometrial cancer.Materials and methods. The study includes 72 histological samples: 36 cases of EIN and 36 cases of EC, 14 of which were combined with EIN. To assess the microsatellite status, immunohistochemical staining of specimens was done with the identification of 4 markers, i. e. MLH1, PMS2, MSH2, MSH6. Results. It was found that out of 36 cases of EIN, only one sample showed loss of the PMS2 and MLH1 genes, which amounted to 3 %; the remaining EIN samples showed microsatellite stability. In 5 (36 %) out of 14 cases of combined EC and EIN pathology, MSI/dMMR was identified. Eight (36 %) out of 22 EC samples were found to have MMR deficiency. Loss of PMS2 increases the likelihood of being classified as EC 9-fold (odds ratio 9.1). With that, the presence of foci of adenocarcinoma in the case of AEH if MSI is confirmed can be asserted with a probability of 93 %. The detection of MSI in a histological sample is more often associated with the presence of EC, while the loss of the PMS2 and/or MLH1 genes increases the likelihood of a cancer diagnosis. If during additional immunohistochemical analysis a loss of these genes is observed, then EC can be diagnosed, even with an ambiguous histological pattern.Conclusion. Detection of MSI/dMMR in AEH indicates the presence of foci of coexisting endometrioid adenocarcinoma with an extremely high degree of probability. Detection of MSI/dMMR in the treatment of EC is advisable at the stage of diagnosis.

Ovarian neoplasms in children and adolescents are rare pathologies (2.6–3.0 per 100,000 patients a year), however, they are sufficiently relevant in pediatric gynecology nowadays. The age of the patients highly correlates with different histological types of ovarian neoplasms. And this is a reason for discussing this disease in different age groups apart. Unfortunately, there are a number of unresolved issues connected with the etiology, pathogenesis and diagnosis. This paper discusses recent information related with the subject “ovarian neoplasms in pediatric gynecology” and particularly questions which require further study.The aim of the work is to conduct a review of recent literature which corresponds to this subject and to discover questions which require further study.The analysis revealed that the etiology and pathogenesis of a number of rare neoplasms has not been discovered fully yet and that can be the cause of the delayed disease diagnostics. Apart from this there are no tools for the preoperative stratification of the risk of malignancy and that can lead to more frequent radical operations for benign tumors.

Background. One of the most common methods of breast reconstruction after mastectomy for malignant tumors is reconstruction using an endoprosthesis. However, this technique is associated with the risk of developing periprosthetic complications. The classic solution to this problem is to remove the endoprosthesis, achieve complete remission of the infectious process and repeat the cycle of reconstructive measures. In this work we present a new approach to the treatment of periprosthetic complications.Aim. To evaluate the effectiveness of the controlled negative pressure system (CNP) in the treatment of periprosthetic breast complications.Materials and methods. From 2019 to 2023, the study included 23 patients who underwent combined/complex treatment for breast cancer, including reconstructive plastic surgery with the installation of endoprostheses, and 1 patient who underwent aesthetic surgery was included. All patients experienced various complications after the reconstructive stage: protrusion of the endoprosthesis, ischemia of the flap and/or local inflammation. To relieve the complications that arose, treatment was carried out using a flushing system and a CNP.Results. The duration of therapy with the sequential installation of a flushing system followed by replacement with a СNP averaged 15 days. In 7 cases out of 24, it was not possible to preserve or reinstall endoprostheses due to thinning of the musculocutaneous flap, resistance of the microflora to the treatment, or relapse of the infectious process. In 17 cases, no complications were recorded after re-installation of endoprostheses for 2 years. As a result of the work, in most cases, within one hospitalization, it was possible to preserve the skin sheath, achieve complete regression of complications and perform repeated reconstructive interventionConclusion. In most cases, the use of a CNP allows you to save the bed for the full installation of a new endoprosthesis. To do this, a number of conditions must be met: absence of microflora growth; presence of granulation after treatment; full thickness and integrity of the musculocutaneous flap. Systemic treatment and a history of radiation therapy are not a contraindication to retaining endoprostheses.

Aim. To identify population characteristics of the PIK3CA gene mutation among breast cancer patients in the Krasnoyarsk region.Materials and methods. The study included 140 patients with breast cancer with a certain mutation status of the PIK3CA gene, observed at the Krasnoyarsk Regional Clinical Oncology Center named after A.I. Kryzhanovsky. Determination of PIK3CA gene mutations (exons 2, 5, 8, 10 and 21) was carried out using commercial kits on equipment from Roche (Germany). Statistical processing of the obtained data was carried out using Microsoft Excel and Statistica 12 software products. The assessment of the factor of influence on the relapse-free and overall survival was carried out by constructing and comparing Kaplan–Meier curves. The result was considered statistically significant at a significance level of p <0.05.Results and conclusion. The overall frequency of occurrence of PIK3CA gene mutations is 38.6 %. The most common mutations are H1047X (55.4 %) in exon 21 and E545K (27.8 %) in exon 10. The median age of breast cancer patients with mutation status in the PIK3CA gene was 58.9 [49.0; 67.0] years, median time to relapse or progression was 62.2 [27.0; 84.0] months. There were no statistically significant differences in relapse-free survival between the presence and absence of mutations (p = 0.8). The effect of changes in PIK3CA on a decrease in overall survival rates (p = 0.047) in breast cancer patients was shown.
Patient Satisfaction with Electronic Sick Leave Certificates: Survey of Family Medicine Outpatient Clinics
Authors: Tušek Bunc Ksenija , Bobek Primož 
Published: July 2024

Purpose: In Slovenia, the transition from paper-based to electronic sick leave certificates (hereafter referred to as eBOLs) started at the beginning of 2020. While paper sick leave certificates are still widely used worldwide, many European countries are already reaping the benefits of using the eBOL system. This survey aimed to determine patients' satisfaction with the new eBOLs and highlight the most significant advantages and disadvantages from the patient's viewpoint.
Methods: A quantitative cross-sectional survey was conducted in Maribor, Slovenia, and the surrounding area to collect quantitative data from family medicine outpatient clinics. Two hundred and fifty patients were randomly selected among those receiving either paper or electronic sick leave certificates. The survey was conducted online with a web survey link and consisted of two parts. The first part included eight items measuring patients’ experiences with electronic and paper sick leave certificates, rated on a five-point Likert scale. The second part consisted of two multiple-choice questions regarding the advantages and disadvantages of eBOLs. The data were analysed using bivariate statistical analysis.
Results: Out of the 250 patients invited to participate in the study, 80 responded, resulting in a response rate of 32%. The mean age of the participants was 46.2 ± 11.2 years, with 56 (70%) women and 24 (30%) men. After more than a year of usage, 57 (71.3%) respondents expressed complete agreement that the eBOL system makes it easier for patients to manage their sick leave. Furthermore, 55 (68.8%) participants considered eBOLs as a good alternative to paper sick leave certificates. Most participants (76 (95%)) considered avoiding additional outpatient visits to manage their sick leave as the most significant advantage of using eBOLs. However, 64 (80%) respondents expressed uncertainty about the data sent by the eBOL system as the most significant disadvantage.
Summary: The survey results showed that patients were already significantly satisfied with the eBOL system when it was first introduced and that their satisfaction increased with continued use. A broader survey including a larger number of Slovenian outpatient clinics and capturing both patients' and doctors' opinions would provide more precise and broader insights into the newly introduced IT system's advantages and disadvantages and its users' satisfaction.
Hybrid fixation for repair of dual forearm fractures of adolescent patients: A case report and literature review
Authors: Movrin Igor 
Published: July 2024

Purpose: To assess hybrid fixation as an alternative option for repair of dual forearm fractures of adolescent patients.
Case presentation: An 11-year-old boy presented with trauma to his right forearm resulting from playing on a trampoline. X-ray examinations confirmed fractures of both the right ulna and radius. Closed reduction and internal ESIN (elastic stable intramedullary nailing) fixation was selected for repair of the radius. Closed reduction of the ulnar fracture was unsuccessful, thus open reduction was performed. However, due to instability of the ulnar fracture after open reduction, internal plate fixation of the ulna was selected. At 3 months after surgery, the patient demonstrated full range of motion with no pain.

Sektor kreatywny zaliczyć można niewątpliwie do jednego z najbardziej obiecujących sektorów gospodarki na świecie. W obszarze jego zainteresowań jest wiele różnych rodzajów działalności, które charakteryzują się innowacyjnością i wysokim potencjałem pracy twórczej. W jego obrębie wytwarza się nie tylko innowacyjne produkty czy usługi, lecz także powstają pomysły, z których korzysta tradycyjny biznes. Niewątpliwie sektor kreatywny wiedzie prym i wskazuje drogę rozwoju innym, mniej dynamicznie rozwijającym się gałęziom gospodarki. Cechuje go kreatywne wykorzystanie wiedzy, zdolność i chęć adaptacji nietypowych rozwiązań i zastosowania nowych technologii, tworzenie nowych modeli biznesowych, jak również otwartość na zmianę i chęć do partnerskiej współpracy. Rosnące znaczenie i przewodnia rola sektora kreatywnego ujawniają się nie tylko w jego wartości ekonomicznej czy coraz szerszym wpływie na społeczeństwo i kulturę.
Warto zaznaczyć, że sektor kreatywny coraz częściej wytycza nowe wzorce zachowań biznesowych i działań, które inne sektory gospodarki powinny naśladować, szczególnie gdy chcą dalej istnieć na rynku, prężnie się rozwijać i osiągać sukces. Dodajmy do tego dynamicznie rozwijające się technologie informacyjno-komunikacyjne (ICT), które stworzyły niespotykane dotąd warunki wykorzystania przez przedsiębiorców sektora kreatywnego takich narzędzi, jak komputer, urządzenia mobilne i sieć internetowa.
W prezentowanej monografii poddano analizie wpływ wykorzystywania technologii informacyjno-komunikacyjnych (ICT) na konkurencyjność oraz rozwój MSP sektora kreatywnego, a także ukazano zależności między charakterystyką właścicieli i cechami przedsiębiorstwa a wykorzystaniem tych narzędzi.
