Nickel oxide (NiO) nanostructure was successfully prepared via reactive DC magnetron sputtering on the soda-lima glass substrate, which can be used for various applications. Xray diffraction (XRD) investigations were used to evaluate NiO with two annealing durations. The results revealed that the deposited films had a cubic structure and polycrystalline nanoparticles. A significant polycrystalline structure could be seen in the sputtered films as a diffraction peak oriented toward NiO (200). Field-emission Scanning Electron Microscopy (FE-SEM) analysis identified the surface morphology of NiO nanoparticles prepared at two different annealing times with the two average sizes (24 and 32 nm) respectively. The samples' roughness was assessed using atomic force microscopy (AFM). Increased annealing time was shown to result in a decrease in grain size. The energy band gap (Eg) expanded with increasing annealing time, according to UV-visible spectroscopy (UV-Vis). FTIR spectroscopy was used to determine the functional groups of NiO nanoparticles and their bonding nature. The results indicate that optical characterizations are more sensitive to the annealing period.

Here we report the structural and physical property of ZnCoxMn(2-x)O4 (x = 0, 0.1 and 0.2) materials. The hierarchical ZnCoxMn2-xO4 (x = 0, 0.1 and 0.2) have been successfully synthesized by hydrothermal method. The surface of the ZnCoxMn(2-x)O4 varies according to its composition which is investigated. The absorption and band gap of the material were measured by UV-Vis diffuse reflectance spectroscopy (DRS) in the range of 200 – 800 nm. It was observed that the band gap gets decreased from the parent compound. The room temperature photoluminescence emission spectra of ZnCoxMn(2-x)O4 (x = 0,0.1 and 0.2) has been investigated. The magnetic property of material shows an antiferromagnetic nature. Further, X-ray photoelectron spectroscopy analysis confirms the substitution of Co on Mn site.

This investigation used sol-gel deposition to create undoped CuO and CuO: Cd thin films. All films of undoped CuO and CuO: Cd phase exhibit four dominating peaks at 35.52°, 38.84°, 53.37°, and 68.23°, which are correspondingly assigned to the (022), (200), (020), and (220) planes, according to X-ray diffraction analysis. The dislocation density reduced from 60.55 to 49.94, the strain decreased from 26.98 to 24.60, and the grain size of the produced films measured by XRD was 12.85–14.15 nm. Atomic force microscopy (AFM) was used to study the morphology. SEM analysis showed increased aggregation with higher Cd content, resulting in a more uniform porous structure. The optical band gap decreases for all samples as the cadmium content increases, ranging from 2.28 to 2.14 eV. Similarly, the refractive index and extinction coefficient values decrease as the cadmium content increases for all samples. The gas sensor detects H2 (375 ppm) using CuO film cadmium doping, which enhances sensitivity, CuO: 4% exhibits highest resistance. Sensitivity decreases with higher doping, indicating reduced sensor responsiveness.

This study reports a simple method for synthesizing the nanoflower-immobilized enzyme (LYH-HRP) using horseradish peroxidase (HRP) as the bioenzyme and layered yttrium hydroxide (LYH) as the inorganic carrier. Utilizing the structural advantage of LYH and the catalytic properties of HRP, a nanoflower-based colorimetric platform was newly designed and applied for sensitively detecting H2O2 and phenol with a detection time of as fast as 5 min. The limits of detection (LODs) for H2O2 and phenol are as low as 0.046 μM and 0.778 μM, respectively. The activity and stability tests showed that the activity of LYH-HRP was 1.52 times that of free HRP, and it maintained 75% of the initial activity after 60 days.

Published: October 2024

Vanda tricolor is currently a protected species because is the occurrence of orchid late blight caused by the Fusarium sp. pathogenic fungus. The objective of this study was to investigate the effectiveness of Rhizoctonia mycorrhizae in inducing resistance against Fusarium sp., the causative agent of late blight, in V. tricolor. The research employed CRBD with three treatments and six replications. Rhizoctonia mycorrhizae were isolated and identified following the procedure outlined by Bayman. Pre-inoculation of Rhizoctonia mycorrhizae was conducted on PDA media, and mycorrhizae were subsequently inoculated onto the roots of V. tricolor seedlings derived from tissue culture. The presence of peloton structures on the roots was determined using the Nakano methods. The Saravanan method was employed to measure peroxidase activity. The results demonstrated that V. tricolor induced by Rhizoctonia mycorrhizae exhibited resistance against Fusarium sp. and displayed the formation of peroxidase enzymes, peloton structures, and lignification. In contrast, the non-induced orchids suffered significant damage to the epidermal tissue of the leaves, did not exhibit an increase in peroxidase enzymes, and failed to form peloton or lignified structures. The novelty of this research is the use of Rhizoctonia mycorrhizae to control orchid late blight diseases at Mount Merapi.

The commercial value of teak wood is associated with its heartwood, which has a naturally darker color than sapwood. To reduce this color disparity, thermal modification can be used to homogenize the color between sapwood and heartwood by minimizing color differences. This research aimed to assess the effectiveness of thermal modification in making the color of teak sapwood similar to that of heartwood. Thermal modification was carried out at 160, 180, 200, and 220 °C for 150 min. Thermal modification of teak sapwood at 180 °C ensured greater color similarity to the heartwood of a fast-growing 16-year-old plantation. The material darkened with increasing process temperature. There was a change in the content of soluble substances, and hot water extraction had greater correlations with hue angle, lightness, and yellowness. Thermal modification also reduced the number of hydroxyl groups and improved the wood’s thermal stability.
Title and power of the ruler of Lithuania during the end of the fourteenth up to the middle of the fifteenth century
Authors: Skurvydaitė Loreta
Published: October 2024

Title of the Lithuanian ruler was developed during the most difficult period of Lithuania's history which coincide with the consolidation of personal and national power of Vytautas in the Polish-Lithuanian union. While establishing the self-independent Lithuanian state, Vytautas create the title of Lithuanian ruler Magnus Dux Lithuaniae, Russiae etc. According to the agreements between Jogaila, the king of Poland and Vytautas, the latter acquired the title of the duke of 'Irakai first, followed by duke of Lithuania and finally the Grand Duke. In foreign affairs, Vytautas acted using the highest title, which he styled himself, while trying to reach this status in the GDL in a legal way. This large variety of Vytautas' titles can be explained by the lack of settled norms concerning the titles. Nevertheless, the political conception of Vytautas - the establishment of an independent Lithuanian state ruled by independent rulers - found its representation in the field of sphragistics and titles. The title of grand duke was a part of Vytautas' political programme which had to be fulfilled by the crown of a king.
When the conflict for the Vytautas heritage started, the position of the Lithuanian ruler towards the sovereign rule as well as the title became very complicated. The title of the grand duke of Lithuania did not coincide automatically with the content of the power of the Lithuanian ruler. It was impossible to become the ruler of Lithuania without the acknowledgment of the grand duke title. Vytautas created this grand duke title using his real power in the country, i.e. being the actual ruler. His successors Švitrigaila and Žygimantas Kęstutaitis, while having this, already created, title tried to consolidate their power. Vytautas established this title while using his power; Žygimantas Kęstutaitis used his title to consolidate his rule over the country. The title of the grand duke became the reality of Lithuanian political life and the rulers used it for their policy.
Title of Lithuanian Ruler Vytautas: When did Vytautas Start to Title Himself as the Grand Duke?
Authors: Skurvydaitė Loreta
Published: October 2024

Lithuanian ruler until the Krėva union used to have different titles. Although, in a variety of names, the title of the Lithuanian ruler was superior to those of the ruling dynasty. As a consequence of the Krėva union, the title of the Lithuanian ruler was being formed in a framework of two poles: on one side it was the title of Jogaila as the king of Poland, and on the other side, it was the title of Vytautas - a local and later an independent ruler of Lithuania.When Jogaila became the king of Poland, the Lithuanian title of the Lithuanian ruler was combined with that of the Polish king. The formation of the title belonging to the local Lithuanian ruler Vytautas was closely related to the title of patrimonial Lithuanian ruler - Jogaila.The first titles defined Vytautas as a local duke ruling over some territories. Under the Astrava treaty, Vytautas became Jogaila's vicegerent in Lithuania. However, on conducting local affairs he did not avoid titling himself as a grand duke of Lithuania in Russian documents. With an increase of his power, Vytautas transferred this title of grand duke to German documents. The relationships with the Orden represent only a very narrow channel with the outside world. At that time the international language was Latin. It was a high-rank diplomatic language. Thus, the Latin document of 1396, where Vytautas titled himself as the grand duke, is of very great importance. With reference to this, we can assume that Vytautas titled himself officially for the first time as the grand duke of Lithuania. Up to 1396, Vytautas was in conformity with the Astrava treaty representing himself as a vicegerent, but from 1396 he stepped over the limits of this treaty.
Characteristics and Utilization of Hospitalizations Among Children With Medical Complexity
Authors: Money Nathan M. , Michelson Kenneth A. , Ramgopal Sriram
Published: October 2024

OBJECTIVES

Hospitalizations for children with medical complexity (CMC) have increased substantially over the past 2 decades and constitute a disproportionate percentage of hospitalization rates and costs among children. We sought to describe the etiology and utilization for hospitalizations of CMC using the Pediatric Clinical Classification System (PECCS).

METHODS

Using the 2019 Kids’ Inpatient Database, we classified hospitalizations for CMC using the PECCS, which groups diagnoses into mutually exclusive, pediatric-specific categories. For the medical, surgical, and medical/surgical PECCS clinical groups, we reported diagnosis groups accounting for ≥1% of hospital encounters for that group. We described admission frequency, cost, payer, length of stay, and mortality rates within each diagnosis grouping using survey-weighted statistics.

RESULTS

We identified 2 315 743 nonlivebirth hospitalizations, of which 712 139 (30.8%) were for CMC. Most (94.4%) hospitalizations occurred at a teaching hospital. Medical diagnosis comprised most hospitalizations (69.2%), whereas hospitalizations for surgical and medical/surgical conditions had a higher median cost. The most common diagnosis groups overall were encounters for chemotherapy, diabetic ketoacidosis, and respiratory failure, whereas the costliest were for necrotizing enterocolitis, transposition of the great vessels, and hypoplastic left heart syndrome.

CONCLUSIONS

We evaluated the most common diagnoses and their associated resource use for hospitalized CMC using the PECCS, providing a more granular view on the etiology, utilization, cost, and outcomes of hospitalizations for CMC. These topics represent high-impact areas for further research and quality efforts for CMC.

Patientdelaktighet i rättspsykiatrisk vård: Vårdprocess och vårdvardag
Authors:   , Söderberg Andreas
Published: October 2024

Purpose: The overall purpose of this dissertation is to describe how patient participation can be understood in the context of high-security care in forensic psychiatry, where individuals are subjected to compulsory care. Design and method: The dissertation is primarily based on a phenomenological foundation, employing a reflective lifeworld approach. Three studies were conducted using interviews, and one study utilized questionnaires with descriptive and comparative statistics. Main result: In many ways, both patients and staff share a consensus regarding patient participation in forensic psychiatric care. From their respective perspectives, similar obstacles and challenges are described, while good care and the experience of participation are strongly linked to what occurs within the caring relationship. However, it cannot be ignored that participation is not solely about good treatment and meaningful relationships. Forensic psychiatric care is carried out under compulsion within a legal system that is difficult for patients to understand and may be perceived as unjust. Participation must therefore be understood from a broader perspective than just everyday care, as everyday care is part of a larger care process. Conclusions: Caregivers and patients associate patient participation in a high-security forensic psychiatric environment with significant caring relationships. A strong caring relationship seems to partially compensate for many situations characterized by non-participation. The studies suggest that staff need support in understanding the complexities of forensic psychiatry in order to better support patients throughout the care process. Therefore, a clinical implication is to help caregivers understand the forensic psychiatric system themselves so that they can explain it to patients and engage in discussions about jurisprudence related to forensic care.
Fenomena Krismuha (Kristen-Muhammadiyah) dalam Pandangan Abdul Mu’ti: Perspektif Hermeneutika Jorge J. E. Gracia
Authors: Faizah Nurul , Anshori Isa
Published: October 2024

This article delves into the phenomenon known as “Krismuha” (Kristen-Muhammadiyah), which refers to the dynamic interaction and relationship between Christian and Muhammadiyah communities, as discussed in Abdul Mu’ti’s work, Kristen Muhammadiyah. The study focuses on such interactions within predominantly non-Muslim regions, employing Jorge Gracia’s hermeneutic theory as an analytical framework. The primary questions explored are: (1) how Abdul Mu’ti conceptualizes the Krismuha phenomenon in Kristen Muhammadiyah, and (2) how this phenomenon can be interpreted through the lens of Jorge Gracia’s hermeneutics. The research utilizes a qualitative methodology, relying on library-based research techniques. The findings indicate that Abdul Mu’ti was motivated to write Kristen Muhammadiyah due to the naturally evolving relationship between Christians and Muhammadiyah members, characterized by voluntary association, mutual comfort, and openness, while still maintaining distinct identities. This unity exemplifies how peaceful coexistence amid diversity—anchored in mutual respect—can foster harmony and well-being within communities. The book further demonstrates that Muhammadiyah, as an Islamic movement, upholds values of pluralism and inclusivity, extending openness to non-Muslim groups.
Agresivitas Verbal Bermuatan Gender di Akun Instagram @Gitasav Perspektif Etika Ibnu Miskawaih
Authors: Sania Rizka , Saad Mukhlisin
Published: October 2024

This article explores gender-based verbal aggressiveness on the Instagram account @gitasav through the lens of Ibn Miskawaih’s ethical framework. It addresses two central questions: What is the nature of verbal aggressiveness on Gita Savitri’s Instagram account, and how can this gender-laden verbal aggressiveness be examined through Ibn Miskawaih’s Islamic ethical perspective? The study adopts a qualitative approach, employing netnography as a method to gather data by downloading and preserving posts and digital traces. Netnography allows the researcher to observe social phenomena within the digital realm. The findings indicate that Ibn Miskawaih’s ethics strongly discourage gender-based verbal aggression. While Ibn Miskawaih does not explicitly discuss aggression in his ethical discourse, his concepts of goodness, happiness, and virtue offer a framework for ethical conduct. This article posits that individuals should strive to maintain a balanced and flexible demeanor across various contexts, as moral virtue is often found in the middle ground between two extremes.
Populist Neo-Nationalism: The Example of Austria
Authors:   Maria Curie-Skłodowska University (Poland), Marczewska-Rytko Maria
Published: October 2024

This article aims to analyze the phenomenon of populist neo-nationalism in Austria and answer the following research questions: 1. How can populism and its type of populist neo-nationalism be characterized?; 2. What are the determinants of populist neonationalism in Austria? 3. What are the ways populist neo-nationalism has been utilized in Austria? The Chantal Mouffe thesis was verified, according to which the development of populism is a response to the shortcomings of liberal and deliberative democracies. The research process used a methodology typical of the social sciences, especially the political sciences. Since the 1980s, we have addressed the growing importance of radical right-wing populism in European politics. Some researchers refer to this phenomenon as new populism or populist neo-nationalism. The party’s growing importance since 1986 was related, among other things, to the principles of Euroscepticism it proclaimed and its demands to limit or even ban immigration. The FPÖ’s achieved the most tremendous success under the government of Jörg Haider. Its entry into the ruling coalition has confused international relations.
The Parties of the Polish People’s Movement in Exile Concerning the So-called Continuity of Polish Statehood in Exile
Authors:   Siedlce University of Natural Sciences and Humanities (Poland), Indraszczyk Arkadiusz
Published: October 2024

This study is of paramount importance as it delves into the attitudes of three Polish People’s Parties active in exile between 1945 and 1990 (Stronnictwo Ludowe “Wolność” (SLW), Polskie Stronnictwo Ludowe (PSL), Polskie Stronnictwo Ludowe – Odłam Jedności Narodowej (PSL-OJN)) towards the recognition of the Polish Constitution of April 1935 and the permanence of the Polish authorities in exile – the so-called legalism. The study primarily used content analysis as the primary research method to analyze the content of the provenance materials of the studied parties, such as political programs, minutes of meetings, articles in the party press, and correspondence. Scientific literature was also used. The research concludes that each of the three researched parties presented different views on the issues indicated above, although the opinions of the SLW and PSL-OJN were quite similar. These parties were in favor of recognizing the Constitution of the Republic of Poland of April 1935 as binding and the construction of the authorities of the Republic of Poland in exile on the basis of the provisions of that Constitution. A different position was presented by the PSL, which rejected the Polish Constitution of 1935 in its entirety.
Evaluation of the “Street and Abroad” Strategy Implemented by Political Opposition in Poland under the Rule of Law and Justice
Authors:   Maria Curie-Skłodowska University (Poland), Marzęda-Młynarska Katarzyna
Published: October 2024

After the 2015 parliamentary elections in Poland, the parties that moved to the opposition declared themselves the “total opposition” and adopted the “Street and Abroad” strategy, the aim of which was to organize anti-government protests in the country and to use foreign fora, including above all EU mechanisms, to fight the new right-wing government, criticize its actions and eventually remove it from power. The paper aims to assess the effectiveness of the strategy adopted by the Polish opposition after seven years of right-wing rule. The subject of particular interest is, on the one hand, the evaluation of the “Street” strategy on the example of mass protests concerning courts, abortion, and the media. On the other hand, the “Abroad” strategy was analyzed through the impact of the European Parliament’s resolution on social mobilization, electoral preferences, and the level of support for the ruling party. For this purpose, the leading indicators of support for opposition parties published by opinion polling centers were used in the examples analyzed.

Authors:   University of Ilorin (Nigeria), Toryuha Aun Thompson
Published: October 2024

One of the ways workers express their displeasure to their respective employers is through industrial action or strike, as it is commonly called. This study investigated the causes and consequences of the Academic Staff Union of Universities strike among public universities in Nigeria. The study employed the descriptive survey method. The population of the study comprised all the 91 public universities in Nigeria; the sample of the study was 400 stakeholders, comprising of lectures, students, parents, transporters, and marketers across all the public universities in the nation, who were selected using multistage sampling procedure of purposive and simple random sampling at their respective public universities. Four hundred respondents were sampled from twelve (12) universities, where 33 respondents were selected from each university. The data collection instrument for this study was a self-designed questionnaire titled “Stakeholders’ Perception of Prevalence, Causes, and Consequences of ASUU Strike among Public Universities in Nigeria: 1999-2022 (SPCCASPUN)”. The questionnaire was on a 5-point Likert scale containing 24 items, validated via experts/professionals with a reliability of 0.87 obtained using a split-half method. At the same time, the data was analyzed using descriptive and inferential statistics of mean rating, percentage, and t-test. Findings of the study revealed, amongst others, that poor budgetary allocation to the education sector, failure of the federal government to honor their long-term agreement, staff bonuses, the politicization of the ASUU strike, revitalization of universities, etcetera are causes of the ASUU strike. As identified by the stakeholders, the consequences include loss of interest in school due to increased social vices, the rush of academic programs, missing out on NYSC and other job opportunities, and loss of sponsorship, among others. It was concluded that both the government and ASUU should come to terms and resolve the issue once and for all to avoid future reoccurrence.

O Processo de Categorização na Perspectiva do Becoming
Authors: Weber Tiziana Brenner Beauchamp , Maciel Cristiano de Oliveira
Published: October 2024

Resumo As abordagens atuais sobre categorias de mercado estão estritamente centradas numa ontologia substancialista. Isso significa que categorias são concebidas como elementos estáticos e de composição simbólica consensual entre produtores, consumidores e intermediários. Nesta perspectiva, categorias mudam de uma fase a outra, e então tendem à estabilidade, ou seja, após momentos pontuais de reconfiguração, os atores do mercado novamente formam consenso sobre a constituição simbólica atual da categoria. Neste ensaio teórico, nosso argumento é de que a constituição simbólica de uma categoria de mercado está em constante devir, abordagem alinhada à ontologia do becoming e oposta à perspectiva substancialista. Propomos um modelo teórico baseado na tríade: atores do mercado – processos interacionais – estrutura radial da categoria. Para isso, apresentamos uma nova explicação: a categorização de um processo contínuo (ongoing) de constituição simbólica que ocorre via processos interacionais entre diferentes atores participantes do mercado, o que resulta em uma estrutura radial categórica com maior aglutinação dos significados relativamente consensuais em seu núcleo e maior dispersão dos significados de maior dissenso em sua periferia. Desta forma, o contínuo contraste entre significados mais centrais e significados mais periféricos operam como o fator becoming das categorias de mercado, como as contradições internas da dialética hegeliana.

ABSTRACT: Several techniques are used to evaluate seed quality; however, most of them are destructive and require considerable execution time. The X-ray test has proven to be an efficient nondestructive technique for evaluating the quality of seeds. This study aimed to evaluate internal damage in ipê-roxo (Handroanthus impetiginosus) seeds through X-ray tests and to investigate how it affects seed germination. Samples from four lots of ipê-roxo seeds were exposed to radiation and, subsequently, the radiographs were analyzed using ImageJ software and the seeds divided into four classes based on their internal morphology: 1) seeds with an embryonic cavity filled with more than 50%; 2) an embryonic cavity filled up to 50%; 3) an embryonic cavity attacked by insects; and 4) an empty embryonic cavity. After that, the seeds were subjected to a germination test and, after 21 days, scored as germinated, nongerminated, dead, and normal and abnormal seedlings. The X-ray test proved to be effective in evaluating the internal morphology of ipê-roxo seeds and their relationship with physiological quality. Radiographic analysis enabled the precise identification of damage, such as embryonic malformation and damage by insects.

ABSTRACT Water is the most important substance in nature and all known life forms on the planet depend on it. Among aquatic species, microalgae and cyanobacteria stand out as indicators of their quality, as their increase can be harmful for human consumption, and their concentrations should be monitored. This research aimed to identify reflectance patterns of the microalgae Chlorella vulgaris and Raphidocelis subcapitata that allow, through the creation of an algorithm, the estimation of their chl-a concentrations. The R software found that cell density and growth were higher in C. vulgaris Pearson correlation of 0.96 (p-value 0.000041) and Chl-a content was higher in R. Subcapitata Pearson correlation of 0.81 (p-value 0.013778). An algorithm made it possible to edit the dependent variable based on statistical models. The best readings for the microalgae used were in the spectral range of 524.84 nm in R. subcapitata and 671.13 nm in C. vulgaris. The use of the spectroradiometer for such an analysis, previously unprecedented, was due to the best cost-benefit for measuring the reflectance of Chl-a. It is expected that these two equations will be used in satellites to remotely check water quality through the incidence of these microalgae.

Abstract Introduction: Cerebral vascular accident (CVA) is the second leading cause of death and is one of the diseases that most generate disability Hemiparesis is the most common motor deficit, and one of its characteristics is asymmetry in weight bearing and in the plantar sup-port area, leading to balance deficits. extracorporeal shock-wave therapy (ESWT) has been shown to be effective in reducing post-stroke spasticity. Objective: To evaluate the effect of a ESWT session on the distribution of plantar pressure and on the static and dynamic balance of hemiparetic individuals after stroke. Methods: Twelve individuals with hemiparesis as a result of stroke in the chronic stage participated in the study. Data collection was divided into two days. On the first day, anamnesis and tests were performed: timed up and go (TUG), four square step test (FSST), and short physical performance battery (SPPB). After carrying out the tests, the distribution of plantar pressure was evaluated using baropodometry. Also on the first day, participants received ESWT in the muscle belly of the gastrocnemius muscle on the hemiparetic side. At the end of the ESWT session and after 7 days, the individuals were reassessed. Results: The results referring to the static and dynamic balance and baropodometry evaluations performed before, immediately after and one week after the application of ESWT did not show a significant difference between the three evaluations in any of the tests and in any of the moments performed. Conclusion: One ESWT session did not affect plantar pressure distribution and static and dynamic balance of hemiparetic individuals after stroke.

Resumo Introdução: O período pós-parto é um momento em que as mulheres são expostas às disfunções da musculatura do assoalho pélvico (DMAP) devido ao período gestacional, mas ainda faltam evidências de qualidade que avaliem o efeito de intervenções sobre a recuperação da musculatura do assoalho pélvico de mulheres no pós-parto. Objetivo: Investigar o efeito do treinamento dos músculos do assoalho pélvico (TMAP) e do low pressure fitness (LPF) sobre o incômodo relacionado às DMAP no pós-parto. Métodos: Estudo randomizado, controlado por placebo, com 35 mulheres que tiveram o parto realizado no Hospital Universitário Materno Infantil (HUMAI), na cidade de Ponta Grossa, Paraná. Foram testados os efeitos do LPF e do TMAP em três grupos: LPF (n = 12), TMAP (n = 12) e intervenção mínima/placebo (IM, n = 11). Os três grupos receberam as intervenções de forma on-line. Resultados: Os treinamentos com LPF e TMAP apresentaram melhores resultados em comparação à IM em alguns distúrbios relacionados às DMAP após 12 semanas de tratamento. O LPF foi mais eficaz sobre o escore global do Pelvic Floor Bother Questionnaire em 6 e 12 semanas, sobre incontinência urinária de esforço em 12 semanas e sobre dispareunia em 6 e 12 semanas. Conclusão: Constatou-se que é possível diminuir o desconforto relacionado às DMAP no pós-parto por meio do LPF e TMAP.
Diversão ou Armadilha? Um estudo exploratório das Apostas Esportivas (Bets) entre Universitários Brasileiros sob a Lente da Teoria do Comportamento Planejado (TCP)

O mercado de apostas esportivas no Brasil (Bets) passou por transformações significativas nos últimos cinco anos, especialmente após a recente regulamentação que busca trazer mais segurança e transparência ao setor. A legalização das apostas, sancionada com a Lei 14.790 em dezembro de 2023, marca um novo capítulo, permitindo que empresas operem tanto online quanto em estabelecimentos físicos. Essa mudança é crucial, pois o Brasil, com sua paixão pelo futebol e uma população de mais de 214 milhões de habitantes, apresenta um enorme potencial para o crescimento desse mercado, que já é avaliado em mais de R$ 100 bilhões, especialmente na população mais jovem. O presente artigo analisou os fatores que afetam a intenção comportamental e as práticas de apostas esportivas entre jovens brasileiros, utilizando a Teoria do Comportamento Planejado (TCP) como plataforma teórica. Além disso, a pesquisa investigou como a gravidade do jogo problemático modera as relações entre os componentes da TCP, a intenção de apostar e o comportamento de apostas em esportes. Os dados foram coletados de 814 jovens universitários de quatro instituições diferentes no Brasil e foram analisados por meio de modelagem de equações estruturais com mínimos quadrados parciais (PLS-SEM) e análise multigrupo. Os resultados mostraram que a atitude em relação às apostas foi o fator mais influente nas intenções de apostar em esportes, seguida pelas normas subjetivas. A intenção comportamental e o controle percebido também se mostraram preditores significativos do comportamento de apostas. O estudo revelou efeitos moderadores importantes da gravidade do jogo problemático, com normas subjetivas sendo mais impactantes entre os jovens com maior gravidade de problemas relacionados ao Transtorno do Jogo (TJ) e Jogo Problemático (JPR), enquanto a atitude se destacou como o principal preditor entre apostadores recreativos. O artigo também discute recomendações para programas de prevenção e tratamento voltados para apostas esportivas e jogos problemáticos, assuntos ainda negligenciados no Brasil.

Aim. To determine the risk factors of biliary fistula after pancreaticoduodenal resection.

Materials and methods. 128 pancreaticoduodenal resections were performed in the period of 2018–2023. Biliary fistula was predicted using a neural network and logistic regression. Prediction accuracy was evaluated by ROC analysis (Receiver Operator Characteristics). The DeLong test was used to compare ROC curves.

Results. Biliary fistula developed in 16 patients (12.5%). Univariate analysis showed that risk factors of biliary fistula included the patient's age >70 years, Charlson comorbidity index >7 points, diabetes mellitus, postsurgical anemia, common bile duct diameter <5 mm, and pancreatic fistula. In multivariate analysis, diabetes mellitus, common bile duct diameter <5 mm, and anemia after pancreaticoduodenal resection increased the risk of biliary fistula. A prognostic multivariate model of biliary fistula development, constructed using an artificial neural network demonstrated higher sensitivity (87.5%) and specificity (95.5%) compared to the logistic regression model (68.8% and 90.2%; p = 0.03).

Conclusion. The use of neural networks in predictive analysis of pancreaticoduodenal resection results can increase the efficiency of biliary fistula prediction.

Aim. Evaluation of the first distant results of the combined experience of liver transplantation for unresectable portal cholangiocarcinoma from two large specialized clinical centers.

Materials and methods. In total, 23 attempts at liver transplantation for unresectable Klatskin tumor were undertaken. Out of them, 10 were conducted at the A.M. Granov Russian Research Center for Radiology and Surgical Technologies (Granov Center), and 13 were conducted at the Minsk Scientific and Practical Center for Surgery, Transplantology, and Hematology (Minsk Center). The maximum tumor size was 5 and 3 cm in patients operated at the Granov and Minsk Centers, respectively. In the Granov Center, neoadjuvant therapy included a combination of endobiliary photodynamic therapy, regional and systemic chemotherapy. Patients were included in the waiting list only in cases of decreased tumor marker levels and in the absence of disease progression and acute cholangitis. In the Minsk Center, stereotactic radiotherapy was used for neoadjuvant treatment in the absence of active cholangitis; the first 3 patients underwent liver transplantation without prior neoadjuvant treatment.

Results. Due to disease progression, six patients were excluded. In three patients at the Mink Center, the diagnosis was not morphologically confirmed after liver transplantation. A total of 14 liver transplantations were performed for unresectable hilar cholangiocarcinoma. After neoadjuvant treatment at the Granov Center, normalization of the CA19-9 marker was observed in four patients, its decrease by 3–4 times was observed in two patients. Liver transplantation was performed in six patients. The average time from the onset of treatment to transplantation was 9.1 months (6–14). Out of the six patients, one was alive for 34 months, with the median overall survival being 22.2 months. Progression was the cause of death in only one patient. Out of the three patients without neoadjuvant treatment at the Minsk Center, two were alive at 16 and 134 months without progression. One patient died after transplantation from disease progression at 24 months. Stereotactic radiotherapy achieved normalization of CA19-9 in four patients; its twofold reduction was observed in one patient. The average time from the onset of treatment to transplantation was six months (3–12). The average CA19-9 tumor marker level by the time of transplantation was 11.3 IU/mL. At 20–26 months, three patients were alive without evidence of disease progression; two patients died of progression after 9 and 59 months.

Conclusion. Liver transplantation for unresectable portal cholangiocarcinoma after neoadjuvant treatment regardless of the methods used is highly promising in carefully selected recipients.

Aim. To evaluate immediate and long-term results of surgical reconstruction of the biliary system in various types of benign obstructive jaundice.

Materials and methods. The study enrolled 110 patients with choledocholithiasis, iatrogenic biliary strictures, common bile duct strictures, as well as strictures of biliodigestive and biliobiliary anastomoses. Patients were divided into 3 groups. Group 1 included 43 patients with multiple choledocholithiasis and bile duct dilatation >15 mm. Group 2 enrolled 35 patients with multiple choledocholithiasis and hepaticolithiasis who were intraoperatively diagnosed with stricture, injury, or pressure ulcers of the common bile duct wall. Group 3 included 32 patients with cicatricial and iatrogenic biliary strictures. The immediate and long-term results of surgical treatment were compared.

Results. In group 1, the survival rate comprised 89.4%, the average duration of surgery amounted to 137 minutes, complications involved wound infection, bile leakage, bile peritonitis. In group 2, the survival rate accounted for 91.4%, the average duration of surgery comprised 192 minutes; strictures of biliodigestive anastomosis were detected in the remote period, and reconstructive surgeries were performed. Group 3 revealed the survival rate of 100%, the average duration of surgery of 215 minutes, and no complications in the long term.

Conclusion. The diameter of the common bile duct, its wall changes, size of gallstones, signs of cholangitis, patency of the bile papilla, and localization of biliary stricture determine the surgical tactics, when performing biliary reconstruction in patients with non-cancerous obstructive jaundice. In case minimally invasive surgery is found impossible under conditions of multiple choledocholithiasis, common bile duct diameter >15 mm, and preservation of its wall, choledocholithotomy with Kerr drainage is considered to be optimal. In case of damage to the CBD wall and patency of the bile papilla, preference shall be given to hepaticoenterostomy. Bile duct reconstruction with stent drainage is indicated for treatment of cicatricial and iatrogenic biliary strictures.
