Hodge-to-singular correspondence for reduced curves
Authors: Mauri Mirko , Migliorini Luca
Published: July 2024

We study the summands of the decomposition theorem for the Hitchin system for

\operatorname{GL}_{n}

, in arbitrary degree, over the locus of reduced spectral curves. A key ingredient is a new correspondence between these summands and the topology of hypertoric quiver varieties. In contrast to the case of meromorphic Higgs fields, the intersection cohomology groups of moduli spaces of regular Higgs bundles depend on the degree. We describe this dependence.
Arbeitsgemeinschaft: Cluster Algebras
Authors: Casals Roger , Keller Bernhard , Williams Lauren K.
Published: July 2024

Cluster algebras, invented by Sergey Fomin and Andrei Zelevinsky around the year 2000, are commutative algebras endowed with a rich combinatorial structure. Fomin–Zelevinsky’s original motivations came from Lie theory but in the past two decades, cluster algebras have had strikingly fruitful interactions with a large array of other subjects including Poisson geometry, discrete dynamical systems, (higher) Teichmüller spaces, commutative and non-commutative algebraic geometry, representation theory, … . In this Arbeitsgemeinschaft, we have focused on 1) basic definitions and theorems, 2) cluster structures on algebraic varieties and 3) the recent connection between cluster algebras and symplectic topology, with its recent application to the construction of cluster structures on braid varieties.
Variational Methods for Evolution
Authors: Hoffmann Franca , Mielke Alexander , Peletier Mark A. , Slepčev Dejan
Published: July 2024

Variational principles for evolutionary systems arise in many settings, both in those describing the physical world and in man-made algorithms for data science and optimization tasks. Variational principles are available for Hamiltonian systems in classical mechanics, gradient flows for dissipative systems, as well as in time-incremental minimization techniques for more general evolutionary problems. Additional challenges arise via the interplay of two or more functionals (e.g. a free energy and a dissipation potential), thus encompassing a large variety of applications in the modeling of materials and fluids, in biology, and in multi-agent systems. Variational principles and associated evolutions are also at the core of the modern approaches to machine learning tasks, since many of them are posed as minimizing an objective functional that models the problem. The discrete and random nature of these problems and the need for accurate computation in high dimension present a set of challenges that require new mathematical insights. Variational methods for evolution allow for the usage of the rich toolbox provided by the calculus of variations, metric-space geometry, partial differential equations, and other branches of applied analysis. The variational methods for evolution have seen a rapid growth over the last two decades. This workshop continued the successful line of meetings (2011, 2014, 2017, and 2020), while evolving and branching into new directions. We have brought together a wide scope of mathematical researchers from calculus of variations, partial differential equations, numerical analysis, and stochastics, as well as researchers from data science and machine learning, to exchange ideas, foster interaction, develop new avenues, and generally bring these communities closer together.

Authors: Ju Yeong Jun , Kim Woorim , Han Jina , Lee Soon Young
Published: July 2024

OBJECTIVES: Studies have suggested an association between hearing loss and anemia. Hearing loss has also been linked to rhinitis, which is characterized by inflammation of the nasal mucous membranes and sinus mucosa. Few studies have concurrently explored the relationships between hearing loss, anemia, and rhinitis. This study was conducted to investigate the association between hearing loss and anemia and to further analyze the potential role of rhinitis in this relationship.METHODS: Data were collected from the 2020 Korea National Health and Nutrition Examination Survey. Hearing loss was measured with an audiometer in a soundproof booth and was defined as at least moderate impairment (as indicated by a pure-tone average of ≥41 dB in the better-hearing ear). The association between hearing loss and anemia was analyzed using multivariable logistic regression. The combined effect of anemia and rhinitis on hearing loss was assessed with an interaction term.RESULTS: Among the 2,772 participants, 477 (17.2%) exhibited hearing loss. Participants with anemia were more likely to experience hearing loss than those without anemia (odds ratio [OR], 1.58; 95% confidence interval [CI], 1.07 to 2.33). Furthermore, the odds of hearing loss were greater in participants with both anemia and rhinitis (OR, 3.79; 95% CI, 1.93 to 7.43) relative to those without either condition.CONCLUSIONS: Anemia was associated with hearing loss in individuals aged 40 years and older. Based on the analysis of combined effects, participants with anemia and chronic rhinitis were more likely to experience hearing loss than individuals without these conditions.
COVID-19 infection and severe clinical outcomes in patients with kidney disease by vaccination status: a nationwide cohort study in Korea
Authors: Woo Jieun , Choi Ahhyung , Jung Jaehun , Shin Ju-Young
Published: July 2024

OBJECTIVES: Patients with kidney disease have been prioritized for coronavirus disease 2019 (COVID-19) vaccination due to their susceptibility to COVID-19 infection. However, little evidence exists regarding these patients’ vulnerability to COVID-19 post-vaccination. Thus, we evaluated the risk of COVID-19 in patients with kidney disease compared to individuals without kidney disease according to vaccination status.METHODS: A retrospective cohort study was conducted using the Korean nationwide COVID-19 registry linked with National Health Insurance Service claims data (2018-2021). Among individuals aged 12 years or older, 2 separate cohorts were constructed: a COVID-19-vaccinated cohort and an unvaccinated cohort. Within each cohort, the risk of COVID-19 infection and all-cause mortality, hospitalization, and emergency room visits within 30 days of COVID-19 infection were compared between patients with and without kidney disease. To adjust for potential confounding, we used propensity score matching. Hazard ratios (HRs) for each outcome were estimated using a Cox proportional hazard model.RESULTS: We identified 785,390 and 836,490 individuals in the vaccinated and unvaccinated cohorts, respectively. Compared to patients without kidney disease, patients with kidney disease were at a higher risk of COVID-19 infection in both the vaccinated cohort (HR, 1.08; 95% confidence interval [CI], 1.02 to 1.16) and the unvaccinated cohort (HR, 1.09; 95% CI, 0.99 to 1.20). Likewise, patients with kidney disease generally were at higher risk for severe clinical outcomes within 30 days of COVID-19 infection. Subgroup and sensitivity analyses showed generally consistent results.CONCLUSIONS: Our study observed excess risk of COVID-19 in patients with kidney disease, highlighting the importance of ongoing attention to these patients even post-vaccination.

Published: July 2024

OBJECTIVES: This study investigated the associations between several obesity-related anthropometric indices and mortality in middle-aged and elderly populations to compare the indices’ predictive ability with that of the body mass index (BMI).METHODS: We analyzed data on 12 indices calculated from 19,805 community-based cohort participants (average age, 63.27 years; median follow-up, 13.49 years). Each index was calculated using directly measured values of height, weight, waist circumference (WC), and hip circumference (HC). We calculated hazard ratios (HRs) and 95% confidence intervals (CIs) for each index using Cox regression and evaluated mortality prediction with the Harrell concordance index (c-index).RESULTS: Adding anthropometric indices to the basic mortality model (c-index, 0.7723; 95% CI, 0.7647 to 0.7799) significantly increased the predictive power of BMI (c-index, 0.7735; 95% CI, 0.7659 to 0.7811), a body shape index (ABSI; c-index, 0.7735; 95% CI, 0.7659 to 0.7810), weight-adjusted waist index (WWI; c-index, 0.7731; 95% CI, 0.7656 to 0.7807), and waist to hip index (WHI; c-index, 0.7733; 95% CI, 0.7657 to 0.7809). The differences between the BMI model and the other 3 models were not statistically significant.CONCLUSIONS: In predicting all-cause mortality, the ABSI, WWI, and WHI models based on WC or HC had stronger predictive power than conventional risk factors but were not significantly different from the BMI model.

Duplex Reverse-Transcription Real-Time Polymerase Chain Reaction Assay Targeting 23S rRNA Single Nucleotide Polymorphisms for the Detection of Flea-Borne Rickettsioses
Authors: Probert William S. , Quintana Alexa C. , Kjemtrup Anne M. , Hacker Jill K.
Published: July 2024

Flea-borne spotted fever and flea-borne (murine) typhus are rickettsioses caused by Rickettsia felis and Rickettsia typhi, respectively, and typically present as undifferentiated febrile illnesses. The relative contribution of these agents to flea-borne rickettsioses in California is unclear. We have developed a duplex reverse transcription real-time polymerase chain reaction (RT-rtPCR) assay targeting R. felis– and R. typhi–specific 23S ribosomal RNA single nucleotide polymorphisms to better understand the respective roles of these agents in causing flea-borne rickettsioses in California. This assay was compared with an established duplex R. felis– and R. typhi–ompB rt-PCR assay and was shown to have 1,000-fold and 10-fold greater analytical sensitivity for the detection of R. felis and R. typhi, respectively. Retrospective testing of clinical specimens with both assays established R. typhi as the major etiologic agent of flea-borne rickettsioses in California.

Published: July 2024

Crimean-Congo hemorrhagic fever (CCHF) is a tick-borne viral disease with a mortality rate reaching up to 40% in humans. Currently, CCHF affects three continents: Asia, Europe, and Africa. An increase in confirmed cases in Africa has been observed since 2000. In Central Africa, several countries have reported the circulation of CCHV virus (CCHFV). However, in Gabon, there is a lack of recent data on the circulation of the virus in the Gabonese population. To provide an overview of the epidemiological situation in Gabon, we tested 3,081 human serum samples collected between 2005 and 2008 in villages throughout the country for anti-CCHFV antibodies. Using a double-antigen ELISA kit, our study found 15/3,081 samples positive for CCHFV. These positive samples were also tested using the Blackbox CCHFV IgG kit and the Luminex technique. These analyses confirmed seven and four positives for the Blackbox CCHFV IgG kit and the Luminex technique, respectively. This study suggests low circulation of CCHFV in the rural human population of Gabon. Competent authorities must survey CCHFV to identify and prevent clinical cases in the human population.

Leishmaniasis, a neglected tropical disease, imposes a notable health burden, especially on immunocompromised individuals such as HIV patients. Recognizing its prevalence and risk factors in specific populations is vital for effective prevention. This study in Satun Province, southern Thailand, aimed to ascertain leishmaniasis prevalence and identify associated risks among HIV-infected patients. A cross-sectional study was conducted among 650 HIV-infected individuals at a tertiary care hospital. Data on demographic characteristics, clinical parameters, and potential risk factors were collected. Individual plasma, buffy coat, and saliva samples were collected. Leishmania infection was determined using the direct agglutination test and nested polymerase chain reaction (nPCR) of nPCR–buffy coat and nPCR-saliva. The association between risk factors and Leishmania infection was assessed with logistic regression analysis. The prevalence of Leishmania infection was 8.61% (56/650). Species was identified among 20 HIV-infected patients as follows: Leishmania orientalis (n = 14), Leishmania martiniquensis (n = 4), and Leishmania donovani complex (n = 2). The factors associated with Leishmania infection included age (adjusted odds ratio [OR] = 1.03), intravenous drug use (adjusted OR = 2.39), CD4 cell count <500 cells/mm3 (adjusted OR = 2.40), and a viral load ≥50 copies/mL (adjusted OR = 5.16). The prevalence of Leishmania infection among HIV-infected patients in Satun Province was considerable. These findings underscore the need for integrated care and targeted interventions to address this infection and improve public health outcomes. Further research and collaborative efforts are warranted to develop effective prevention and control strategies for Leishmania infection in the HIV-infected Thai population.
Unique Approach of Modern Automotive Exhaust System Mountings Design
for NVH Improvement
Authors: Sarna Amit Kumar , Singh Jitender , Kumar Navin , Sharma Vikas
Published: July 2024

Minimizing vibration transmitted from the exhaust system to the vehicle’s
passenger compartment is the primary goal of this article. With the introduction
of regulatory norms on NVH behavior and emissions targets, it has become
necessary to address these issues scientifically. Stringent emissions
regulations increased the complexity of the exhaust system resulting in
increased size and weight. Exhaust system vibration attenuation is essential not
only from the vehicle NVH aspects but also for the optimized functionality of
the subsystems installed on it. Based on earlier studies, this work adopts a
more thorough strategy to reduce vehicle vibration caused by the exhaust system
by adjusting it to actual operating conditions.

To achieve this, a complete vehicle model of 22 DOF is considered, which consists
of a powertrain, exhaust system, chassis frame, and suspension system. A method
for evaluating static and dynamic vibration response is proposed. Through the
use of the vehicle’s rigid body modes and actual field events, design indicators
are carefully analyzed and validated. Based on actual operating conditions, the
two main load cases that are taken into consideration are idling and the sweet
spot operating zone. To define the sweet spot zone of the dominant
vehicle/engine-operating scenario, the vehicle duty cycle is monitored
experimentally.

The baseline 22 DOF model results show a degradation in exhaust vibration
performance in both load cases as its yaw and bounce modes are falling into the
resonance region of the idle and sweet spot operating zone load cases,
respectively. The acceleration reduction of nearly 10–20 dB in static events,
and nearly 10 dB in dynamic events can be evident in the proposed model. The
proposed system’s outcomes demonstrate an improvement in the eigenvalues of the
yaw and bounce modes, which in turn enhances the vehicle’s overall NVH
performance in both static and dynamic load cases. Thus, the study suggests that
designers should consider the real field events’ load cases for modern exhaust
system-mounting optimization to achieve improvement in NVH behavior, fuel
efficiency, emissions performance, and durability aspects of the vehicle.
Optimal Layout of Suspension System Employing Mechatronic Inerter for
Comfort Enhancement Based on Structure-Immittance Approach
Authors: Kolta Michael M.H. , Mansour Nader A. , Lashin Manar , Soliman Aref M.A.
Published: July 2024

The usage of the inerter and its studies has greatly developed in recent years as
it offers better performance compared to passive systems and has lower cost and
power consumption than active and semi-active systems. This article focuses on
studying a half-vehicle model to obtain the optimal layout of the mechatronic
inerter, spring, and damper suspension system (ISD) for comfort enhancement with
the aid of the structure-immittance approach, ensuring structural
simplicity.

The mechatronic inerter, which consists of a single capacitance, resistance, and
inductance, is added to a half-vehicle model composed of an inerter, spring, and
damper. All possible layouts are studied to achieve the optimal design layout.
Evaluation criteria such as the performance index, system peak-to-peak value,
and settling time are utilized to assess body acceleration, thereby improving
passenger comfort. Furthermore, the system’s impact on dynamic tire load and
suspension working space under diverse road conditions is analyzed. Theoretical
analyses conducted using MATLAB/Simulink demonstrate that the novel mechatronic
ISD layout significantly enhances body acceleration performance compared to
conventional passive systems, switchable hydraulic ISD systems, and fuzzy
logic-controlled three-setting switchable dampers.
Jak (i dlaczego) kłócono się o język badań literackich?
Authors: Hellich Artur
Published: July 2024

Przedmiotem artykułu jest omówienie i interpretacja z perspektywy socjologii wiedzy kilku dyskusji dotyczących stylu i terminologii badań literackich, jakie przetoczyły się w XX i XXI wieku w kręgach warszawskich literaturoznawców. W pierwszej części artykułu autor omawia spory o terminologię wersologiczną w okresie przed- i powojennym w kontekście jej społecznego zasięgu, następnie przechodzi do zreferowania dyskusji z lat 50. i 60., krytycznych względem scjentyzacji języka humanistyki. Druga część artykułu jest natomiast poświęcona omówieniu dwóch debat współczesnych: wokół recepcji Ilustrowanego słownika terminów literackich (tu powraca problem społecznego zasięgu badań humanistycznych) oraz wokół wymogu schematyzacji wywodu humanistycznego, związanego z wpływem kapitalizmu na humanistykę, i łączącymi się z tym zarówno szansami, jak i zagrożeniami. Sięgając do socjologii P. Bourdieu i kontekstowo do jej nowszych interpretacji (A. Zysiak), a także wspierając się ujęciem emocjonologicznym (S. Ahmed), autor stawia tezę, że każde stanowisko w sporze dotyczącym języka humanistyki (jego pożądanego stylu i preferowanej terminologii) jest nie- uchronnie polityczne. Wychodząc od tego rozpoznania, autor każdorazowo wskazuje w omawianych stanowiskach konkretnych badaczy na polityczny wymiar ich argumentacji: elitarystyczno-konserwatywny, tożsamościowo-liberalny lub egalitarystyczno-lewicowy.

Educational policy in times of war 2022: A case study of the Twitter of the Ministry of Education and Science in Poland
Authors: Halska-Pionka Bogna , Kot Joanna
Published: July 2024

The aim of the conducted research was to analyze the activity of the Polish Ministry of Education and Science on Twitter and to diagnose and then describe the perspective (experiences, reflections, postulates) of Twitter users, thus enabling the analysis and evaluation of activities undertaken in the field of shaping education policy in times of Russian aggression to Ukraine.
The subject of the research were entries and comments posted on the Twitter platform on the account of the Polish Ministry of Education and Science in Poland placed in the time period from February 24, 2022 (the first day of Russia’s invasion of Ukraine) to June 1, 2022 (celebration related to Children’s Day). The collected data were analyzed in the MAXQDA program in accordance with the prepared – described in detail in the article – code key. As part of the research, a total of 259 posts and 2,339 comments were analyzed. It turned out that Twitter users are reluctant to create recommendations (3% of all entries), while the vast majority of comments contain negative opinions and experiences related to education policy. The analysis also showed a worrying trend towards an increasing number of hate speech comments. Users often used the Twitter platform to mock politicians, but also made statements directed against the Ukrainian people.
Based on the conducted research, it is extremely difficult to describe the activities undertaken in the field of education policy by the Polish Ministry of Education and Science. It should be noted that the analyzed entries in most cases are only very short messages, often referring only to visits or speeches by politicians. At the same time, it is worth emphasizing that comments posted by users rarely enter into substantive polemics, because they are usually only a vent for very negative emotions.

Published: July 2024

W artykule przedstawiono wykorzystywane w kryminalistyce psychologiczne nurty: behawioralny i ewolucyjny. Powyższe nurty są nierozłączną częścią nauki (kryminalistyki), zajmującej się wykrywaniem prawnie określonych ujemnych zjawisk społecznych, a w szczególności przestępstw i ich sprawców oraz udowadniania istnienia lub braku związku między osobami, a zdarzeniami. Autor wprowadza i zapoznaje czytelników z najważniejszymi informacjami na temat przedmiotowych nurtów. Wskazuje na trwający od wielu lat spór wśród ludźmi nauki na temat tego, który z nurtów jest bardziej efektywny i przynosi większe korzyści w pracy z ludźmi, prowadzeniu badań czy też ściganiu przestępców. Wskazuje na fakt, iż organy ścigania mogą uzyskać większą efektywność w zwalczaniu i wykrywaniu przestępczości dzięki opieraniu się na naukowych opracowaniach, dedykowanych psychologii kryminalistycznej. Autor w przedmiotowym artykule porusza temat kryminalistyki w Żandarmerii Wojskowej, która w efektywny sposób wykorzystuje dostępne naukowe zasoby, między innymi poprzez ciągłe specjalistyczne szkolenia oraz specjalistyczno- szkoleniową jednostkę „Centrum Szkolenia ŻW w Mińsku Mazowieckim”. W zakończeniu główny nacisk położono na konieczność wykorzystywania wiedzy z naukowych źródeł, która w znaczny sposób mogłaby przyczynić się do zwiększenia efektywności w procesach: ujawniania, wykrywania, przeciwdziałania i zwalczania przestępczości w naszym kraju.

Comparative Study of Reinforced Concrete Using Human Hair and Aluminum Fibres
Authors: P. Shahla Thasni , E Sandra , N Najil , Saneed PP Muhammed , T Jithma
Published: July 2024

This study investigates the efficacy of human hair and aluminum fibres as reinforcements in concrete, analyzing their impact on compressive, flexural, and tensile strengths. Different fibre percentages (0%, 0.5%, 1%, and 1.5% by weight of cement) are systematically incorporated into concrete mixtures. Compressive strength tests on cubes, flexural strength assessments on beams, and tensile strength evaluations on cylinders reveal insights into the material's load-bearing, bending, and stretching capacities. Human hair-reinforced concrete showed significant improvements in compressive strength. Results indicate a gradual strength increase in Human Hair Fibre Reinforced Concrete (HHFRC) up to an optimal percentage. At the same time, Aluminum Fibre Reinforced Concrete (AFRC) shows significant enhancement in higher fibre content. AFRC's superior mechanical properties stem from aluminum fibres high tensile strength and stiffness, enhancing bond formation and resulting in denser, stronger concrete. These findings inform the selection of fibre reinforcement for concrete structures tailored to specific project needs.
The ‘feverish’ society and the aims of education
Authors: Papastephanou Marianna
Published: July 2024

Borrowing the Platonic metaphor of a ‘feverish’ society, this article discusses the argument that a critical stance toward our contemporary realities makes a revisiting of educational aims more urgent. The article begins with how aims have been tackled in educational philosophy. The head-on educational-philosophical engagement with aims-talk has been diminishing. There have been socio-political developments unfavourable to aims-talk, related to hegemonic, neoliberal mindsets. Neoliberalism discourages the theorization of educational aims that challenges its conventional ‘wisdom’. There have also been philosophical reasons for the decline in the frequency of aims-talk, related to some postmodern positions that combat modern assumptions of ‘ultimate’ aims and register the possibility of an ‘education without aims’. Against the tendency to under-theorize educational aims, the article critically explores why our contemporary societies may be described as ‘feverish’ and what this entails for theorizing educational aims. My main claim is that the educational aims-talk should be reinvigorated and the related fault lines rethought from a more enlarged viewpoint.
Thinking with Spinoza, Locke, and Dewey about self-control, education, and democracy
Authors: Harðarson Atli
Published: July 2024

In the 17th century Spinoza and Locke wrote about education as aiming at self-control. In the 20th century Dewey argued for a similar view in Experience and education, where he described education as enabling people to have control over their own lives. These three philosophers all saw self-control as involving both the ability to make well-advised decisions and the competences necessary to follow them through. In the first half of the paper their theories are rephrased and explained. After that, the elements they have in common are analysed and supported with references to recent philosophical and psychological work on self-control. It is also argued that these common elements apply not only to individuals but also to groups and communities. The concluding section is a reflection on the relevance of what they said to modern discourse on educational aims and education for democracy.

ince their inception, reinforced concrete structures have been continually improved in light of new knowledge, technologies, and/or materials, making older structures like the subject in question significantly different from today’s common solutions in their design and implementation. This makes their revitalization a demanding and multidisciplinary task. This paper provides a brief excerpt from the revitalization project of one of the oldest engineering RC structures in Vojvodina – the water tower within the cement factory in Beočin. The facility stands as a very important monument of construction heritage, but over its 120 years of use, it has suffered significant damage that even jeopardize its bearing capacity. Numerous activities that conditioned or accompanied the design process are summarized, such as geometry identification, detailed visual inspection, in-situ and laboratory testing, repair and rehabilitation measures for elements, with the main focus given to numerical analysis and adopted structural solutions.

After a fire broke out in a nearby discotheque on July 2, 2012, the fire soon spread to the roof structure of the Bora Stanković Theater in Vranje and then to the entire theater building. Of the building built in 1892 by Vranje merchant Jančo Jovanović Baldžija, only the battered brick walls remained, while the entire hall with 400 seats, two theater clubs, the stage with equipment and the basement were completely destroyed. As part of the reconstruction works, it is planned to design a complete new construction of the roof, the main hall and the balcony. The stage was redesigned in part of the basement, which necessitated the underpinning of the existing foundations. In order to transfer the entire area of the building to part of the basement, new RC walls are designed while part of the old stone walls are kept. Partially damaged masonry walls are additionally stiffened with vertical tie-columns. This paper presents the reconstruction and rehabilitation measures carried out at the Bora Stanković theater in Vranje, which is successfully used today after all the completed works.

In steel constructions welding is one of the favourable joining methods. To consider negative effects of the joining residual stresses and distortions can be found with different welding simulation tools. The usage of different tools will require know how of the process as well as the input of energy, geometry and the material. Also there is a large time amount necessary the build- up the working model with the required boundary conditions. To reduce calculation time a welding tool was developed and will be used to analyse in a quite simple and easy-applicable manner stresses. The simplified approach will be compared with earlier full scale simulation efforts. The application of such approach for considering welding effects in the component design of welded plate girders is however still quite unusual even in steel research. Especially multi-layer welds which are found in joining thick plates require multiple calculation steps and generate the need of simplifications.

The case study of the reconstruction and strengthening of reinforced concrete frame structure of one stall building is presented in the paper. A part of the building has collapsed due to insufficient tension reinforcement at the beam-column joint and at the midspan. The reconstruction measures consist of the replacement of the collapsed frames with the new ones, as well as strengthening of undamaged frames. The strengthening method with additional steel plates in tension zone is proposed, which is verified based on the stress-strain analysis of strengthened cross-sections.

In today's competitive business era, entrepreneurs are faced with the challenge of growing their businesses in an increasingly competitive environment. One of the main strategies for growth is business expansion, which often requires additional funding. Internal funding is often insufficient, so many companies turn to external sources of funds, such as through an Initial Public Offering (IPO). IPOs are defined in Law No. 8/1995 on Capital Markets and offer various benefits, including increased share ownership by individual investors, expansion of product distribution, and long-term investor support. However, some listed companies choose not to list their shares on the Indonesia Stock Exchange, a decision that complies with the Capital Market Law. A company can be classified as a public company if it meets certain criteria, including the number of shareholders and minimum paid-up capital. While not listing on the stock exchange may have its own benefits and drawbacks, this decision has significant implications for the company's operations. This study explains the dynamics and implications of various funding strategies in the current business context, providing insights into the IPO decision and the choice not to list on the stock exchange.

Introdução: A obesidade configura uma importante síndrome metabólica que cursa com um aumento da morbidade e mortalidade. Nos casos de obesidade grau III, o tratamento cirúrgico é empregado como método com maior taxa de sucesso para controle ponderal. Para tanto, é necessário manejo anestésico adequado. Desse modo, o objetivo deste trabalho foi avaliar os principais aspectos da anestesia em cirurgias bariátricas com base em revisão retrospectiva e bibliográfica. Objetivo: alcançar os melhores resultados em relação ao manuseio anestésico em pacientes obesos submetidos à cirurgia bariátrica. Materiais, sujeitos e métodos: Trata-se de uma revisão sistemática a partir de uma consulta de artigos publicados nas plataformas LILACS, PubMed – NCBI e SciELO entre os anos de 2018 e 2023, com as palavras chave: “obesidade mórbida”, “cirurgia bariátrica”, “anestesia bariátrica” e “gastroplastia”. Resultados e discussão: Não há consenso sobre a técnica anestésica ideal em pacientes obesos. É importante que o método por bloqueio ou anestesia geral seja delineado de acordo com as comorbidades de cada paciente, e com o foco na recuperação precoce e diminuição do risco de complicações e efeitos colaterais de opióides. Deve-se ainda considerar a duração, a técnica cirúrgica e os recursos disponíveis em cada serviço de saúde. Considerações Finais: é necessário conhecer as particularidades e desafios da anestesia no paciente obeso, posto que a analgesia no intra e no pós-operatório de cirurgias bariátricas é um componente importante para reduzir o tempo de internação hospitalar e complicações. No entanto, urge novos estudos para que possam ser definidos novos protocolos de anestesias em cirurgias bariátricas.

Introdução: Tendo em vista que a obesidade compreende doença multifatorial, pesquisa-se sobre o manejo anestésico em pacientes submetidos a cirurgia bariátrica, a fim de evidenciar fatores relacionados à anestesia capazes de contribuírem para diminuição de complicações e tempo de internação hospitalar na população obesa. Para tanto, é necessário compreender as complicações relacionadas à anestesia na população obesa, além de elucidar estratégias adotadas pelos estudos associadas à melhoria de todo o processo pré-operatório, pós-operatório e recuperação desses pacientes. Objetivo: Mostrar, através de uma revisão sistemática da literatura, os aspectos do manuseio anestésico de pacientes submetidos à cirurgia da obesidade, com levantamento das comorbidades e possíveis complicações. Materiais/Sujeitos e Métodos: Realiza-se, aqui, uma pesquisa de caráter qualitativo e bibliográfico, realizada através da técnica de revisão de literatura, cuja base de dados principal refere-a PubMed, por meio dos descritores em língua inglesa e auxílio de operadores booleanos, sendo incluídos artigos que descreviam com clareza a metodologia utilizada e confiabilidade de seus resultados. Resultados e discussão: Verifica-se que os autores objetivam a identificação de novas técnicas anestésicas de modo a reduzir a incidência de complicações e obtenção de melhores resultados nos pós-operatórios dos pacientes. A avaliação pré-anestésica adequada realizada por profissional capacitado é necessária de modo a contribuir para o planejamento individualizado e adaptado a cada paciente, permitindo a visualização geral do quadro, associando comorbidades às possíveis complicações. As comorbidades de maior incidência e que mais comumente cursam com complicações anestésicas compreendem hipertensão arterial sistêmica, osteoartrose, apneia obstrutiva do sono, doença do refluxo gastroesofágico, diabetes mellitus e asma. Acerca disso, algumas estratégias têm sido propostas no manejo destes pacientes, apresentando resultados satisfatórios, como exemplo o conceito de anestesia livre de opioides, uma vez que a analgesia, quando realizada com medicamentos alternativos à morfina, como cetamina e dexmedetomidina, diminui os efeitos colaterais dos opióides, como depressão respiratória induzida por opioides. Considerações Finais: O planejamento anestésico de pacientes obesos submetidos a cirurgia bariátrica deve ser realizado de maneira individualizado, uma vez que estes pacientes possuem maior número de comorbidades que a população em geral, e por consequência maiores taxas de complicações. Ressalta-se a importância de estudos futuros acerca do tema, a fim da abrangência do conhecimento e contínua promoção de melhorias a estes pacientes.

Published: July 2024

Introdução: A dor pélvica crônica (DPC) é uma condição que afeta uma parcela significativa da população feminina, utilizando regularmente diversos recursos médicos para fins diagnósticos. Definida por um quadro álgico em região pélvica ou abdominal, com persistência maior que seis meses, a DPC pode ser debilitante e complexa em sua etiologia. Diagnósticos tradicionais frequentemente falham em determinar a causa exata da dor, levando a abordagens ineficazes e frustração, tanto por parte de médicos quanto pacientes. Nos últimos anos, o emprego da laparoscopia na investigação da etiologia da DPC tem sido cada vez mais utilizado, sendo considerado por muitos o passo inicial da investigação (Kopelman et al., 2010). Objetivo: Este estudo tem como objetivo analisar a aplicabilidade da laparoscopia no diagnóstico de dores pélvicas e abdominais crônicas, cuja etiologia é desafiadora de determinar apenas do ponto de vista clínico. Materiais, sujeitos e métodos: Para a execução deste artigo de revisão, foram estudados artigos científicos e de revisão publicados em plataformas digitais como PubMed e SciELO. Resultados e discussão: A laparoscopia, um procedimento minimamente invasivo, foi adotada como ferramenta diagnóstica e terapêutica no manejo da DPC. Dentre um grupo de estudos, apenas 25% das pacientes submetidas a tal procedimento não tiveram diagnóstico concluído. Na maioria dos casos, foram encontradas evidências de endometriose, aderências pélvicas e varizes pélvicas, sendo a endometriose a mais prevalente (Departamento de Ginecologia e Obstetrícia da Faculdade de Medicina de Botucatu – Modotte, 2005). Considerações finais: A laparoscopia, além de rápida e segura, mostrou-se um método com grande eficácia na avaliação da dor pélvica crônica. Mulheres em idade fértil, o grupo mais acometido, conseguiram seu diagnóstico definitivo e melhora da qualidade de vida.
