OBJECTIVE:

The objective is to explore the chest computed tomography (CT) and pulmonary function findings of coronavirus disease 2019 (COVID-19) survivors 1 month after discharge.

METHODS:

We retrospectively analyzed the chest CT and pulmonary function findings of 158 (COVID-19) survivors who were discharged and followed up at Wuhan Red Cross Hospital from April 9 to May 10, 2020.

RESULTS:

Follow-up chest CT revealed that pulmonary lesions in all patients were clearly absorbed and dissipated. One month after discharge, 125 (79.1%) patients had residual imaging abnormalities, mainly light ground-glass opacities (44.9%) and light patchy shadows (38.6%). Other features included fibrous cord lesions in 90 cases (57.0%), pulmonary nodules in 46 cases (29.1%), pleural thickening in 44 cases (27.8%), and mediastinal lymphadenopathy in 81 cases (51.3%). Among 158 COVID-19 survivors, 124 were tested for pulmonary function. Pulmonary function tests revealed pulmonary function impairment in 10 patients (8.1%), restrictive ventilation dysfunction in 16 (12.9%), and pulmonary diffusion dysfunction in 48 (38.7%). Residual lung lesions and pleural thickening were negatively correlated with DLCO% (P < 0.05).

CONCLUSION:

COVID-19 patients have characteristic findings on chest CT and pulmonary function testing. Identifying these findings is helpful to dynamically monitor the disease prognosis.
Cyclic Gerstenhaber–Schack cohomology
Authors: Fiorenza Domenico , Kowalzig Niels
Published: January 2022

We show that the diagonal complex computing the Gerstenhaber–Schack cohomology of a bialgebra (that is, the cohomology theory governing bialgebra deformations) can be given the structure of an operad with multiplication if the bialgebra is a (not necessarily finite dimensional) Hopf algebra with invertible antipode; if the antipode is involutive, the operad is even cyclic. Therefore, the Gerstenhaber–Schack cohomology of any such Hopf algebra carries a Gerstenhaber (resp. Batalin–Vilkovisky) algebra structure; in particular, one obtains a cup product and a cyclic boundary

that generate the Gerstenhaber bracket, and that allows to define cyclic Gerstenhaber–Schack cohomology. In case the Hopf algebra in question is finite dimensional, the Gerstenhaber bracket turns out to be zero in cohomology and hence the interesting structure is not given by this

-algebra structure but rather by the resulting

-algebra structure, which is expressed in terms of the cup product and

Finite-element approximation of a phase field model for tumour growth
Authors: Eyles Joe , Nürnberg Robert , Styles Vanessa
Published: January 2022

We consider a fully practical finite-element approximation of a diffuse interface model for tumour growth that takes the form of a degenerate parabolic system. In addition to showing stability bounds for the approximation, we prove convergence, and hence existence of a solution to this system in two space dimensions. Several numerical experiments demonstrate the practicality and robustness of the proposed method.
Fully nonlinear singularly perturbed models with non-homogeneous degeneracy
Authors: Bezerra Júnior Elzon C. , da Silva João Vítor , Ricarte Gleydson C.
Published: January 2022

This work is devoted to studying non-variational, nonlinear singularly perturbed elliptic models enjoying a double degeneracy character with prescribed boundary value in a domain. In its simplest form, for each

\varepsilon>0

fixed, we seek a non-negative function

u^{\varepsilon}

satisfying

\begin{cases} \left[|\nabla u^{\varepsilon}|^p + \mathfrak{a}(x)|\nabla u^{\varepsilon}|^q \right] \Delta u^{\varepsilon} = \zeta_{\varepsilon}(x, u^{\varepsilon}) & \operatorname{in } \Omega,\\ u^{\varepsilon}(x) = g(x) & \operatorname{on } \partial \Omega, \end{cases}

in the viscosity sense for suitable data

p, q \in (0, \infty)

,

\mathfrak{a}

and

g

, where

\zeta_{\varepsilon}

behaves singularly as

\text{O} (\varepsilon^{-1})

near

\varepsilon

-level surfaces. In such a context, we establish the existence of certain solutions. We also prove that solutions are locally (uniformly) Lipschitz continuous, and they grow in a linear fashion. Moreover, solutions and their free boundaries possess a sort of measure-theoretic and weak geometric properties. In particular, for a restricted class of nonlinearities, we prove the finiteness of the

(N-1)

-dimensional Hausdorff measure of level sets. We also address a complete and in-deep analysis concerning the asymptotic limit as

\varepsilon \to 0^{+}

, which is related to one-phase solutions of inhomogeneous nonlinear free boundary problems in flame propagation and combustion theory. Finally, we present some fundamental regularity tools in the theory of doubly degenerate fully nonlinear elliptic PDEs, which may have their own mathematical interest.
Rekrutacja na studia wyższe w początkach stalinizmu na przykładzie województwa poznańskiego
Authors: Jankowiak Stanisław
Published: January 2022

Zmiana systemu po II wojnie światowej związana była z pojawieniem się nowej filozofii kształcenia. Dla komunistycznej władzy najważniejszym celem było dostarczenie krajowi nowych, socjalistycznych i świadomych swej roli w przebudowie kadr. Kryteria polityczne były więc ważniejsze od merytorycznych. Założeniem politycznym było stworzenie nowej, robotniczo- -chłopskiej inteligencji, która rozumiałaby swą rolę w walce o socjalizm. By tego dokonać, należało zrewolucjonizować zasady naboru do szkół średnich i wyższych. O przyjęciu na studia nie miała więc decydować wiedza, ale zaangażowanie polityczne i społeczne. Należało też, i to akurat nie budziło wątpliwości, pozwolić młodzieży nadrobić zaległości wynikające z wojny. Konstruowane polityczne założenia nie we wszystkich przypadkach przełożyły się na praktykę działania. Mimo jednoznacznych wytycznych i kluczowej roli urzędów bezpieczeństwa w opiniowaniu kandydatów, skład socjalny studentów nie uległ radykalnej zmianie. Nie oznacza to, że polityka komunistów nie wyrządziła szkody części zdolnej młodzieży, której ze względów klasowych zamknięto możliwość zdobywania wyższego wykształcenia.

College enrollment in the period of Stalinism as exemplified by the Poznań voivodeship

Systemic transformation following the Second World War brought a new philosophy of education. For the communist authorities, the most important goal was to provide the country with new, socialist workers, who were aware of their role in the process of reconstruction. Therefore, political criteria took precedence over any others. The political objective was to create a new “intelligentsia” comprising workers and peasants who would understand their role in the fight for socialism. In order to achieve that objective, rules of high school and college enrollment had to be revolutionized. Political and social engagement were to be the decisive factors in college admissions — not knowledge. Young people were also meant to be allowed to make up for the time lost because of the war — however, this particular demand does not raise any questions. Political objectives did not translate into practice in all cases. Despite clear guidelines and the key role of security offices when reviewing the candidates, the social composition of students did not change radically. This does not mean that the communist policy did not do any harm to some talented young people who were precluded from gaining college education for class reasons.
Taksa wojewodzińska Zbąszynia w XVIII w. jako źródło do badań nad historią gospodarczą miasta szlacheckiego
Authors: Frąś Marcin
Published: January 2022

Nadrzędnym celem poniższego artykułu jest przybliżenie tekstu taksy podwojewodzińskiej na towary spożywcze dla miasta Zbąszynia z 1751 r. Źródło zostało wniesione do księgi miejskiej Zbąszynia z lat 1592–1807, która przechowywana jest w Bibliotece Kórnickiej PAN w Kórniku. Na tle dotychczas wydanych tego typu źródeł prezentuje się ona miernie. Głównie ze względu na to, że nie obejmuje pozostałych rzemiosł istniejących wówczas w mieście. Niemniej jednak jej niewątpliwą zaletą jest fakt, iż jest to pierwszy tego typu przekaz z dawnego województwa poznańskiego. Co więcej, przybliża nas do poznania warunków życia codziennego w małym mieście szlacheckim. Podano w niej ceny gorzałki, pieczywa i mięsa, czyli głównych artykułów stanowiących dietę ówczesnych ludzi.

Voivodeship tariff in Zbąszyń in the 18th century as a source of research on economic history of a private town

The main objective of this article is to present the text of the so-called sub-voivodeship tariff on food products for the town of Zbąszyń from 1751. This source was entered into the Zbąszyń municipal registry for the years 1592–1807, which is kept in the Kórnik Library of the Polish Academy of Sciences in Kórnik. Compared to other similar publications, it is far from impressive. The main reason is the fact that it does not cover other trades which existed in this town at the time. Still, one of its major advantages is the fact that it is the first such source from the former Poznań voivodeship. Furthermore, it helps us learn more about living conditions in a small private town. It lists prices of spirits, bread, and meat, which were the basic alimentary products consumed by people back then.

Muzyczne tajemnice Poznania – kino Słońce i jego wyjątkowe organy
Authors: Bigosiński Adam Konrad
Published: January 2022

Niniejszy artykuł jest kolejnym przyczynkiem do dziejów muzycznych Poznania, a skupia się na opisie i charakterystyce najbardziej wyjątkowych w skali Polski organów „Muza”, które od 1927 r. znajdowały się w kinie Słońce. Najnowocześniejsze kino w Poznaniu mogło poszczycić się pierwszymi organami typu kinowego na terenie Polski, które w dodatku zostały zbudowane na wzór instrumentów amerykańskich przez polską firmę Dominika Biernackiego (braci Biernackich). Posiadały one szereg urządzeń imitujących odgłosy przyrody czy życia codziennego, m.in. burzę, syrenę czy kukułkę. Niestety, powojenny los organów nie jest znany, a ślad po nich zaginął. Jak dotąd, żaden inny polski zakład budowy organów nie zdołał powtórzyć tej wyjątkowej realizacji. Całość dopełniona jest krótką charakterystyką muzyki wykonywanej w Słońcu, szczególnie przez znanego poznańskiego spikera Ludomira Budzińskiego, który koncertował pod zmienionym nazwiskiem Szeliga.

The musical mysteries of Poznań — the “Słońce” cinema and its unique organ

This article is yet another contribution to a history of music in Poznań. It focuses on the description and the story of the most exceptional organ in Poland — the “Muza” organ, which was housed in the “Słońce” cinema since 1927. The most technologically advanced cinema in Poznań was the proud owner of the first organ dedicated to cinema performances in Poland. It was made by a Polish company run by Dominik Biernacki (The Biernacki Brothers) based on the American design. It was equipped with a number of devices imitating the sounds of nature or of every day life, such as storms, sirens, or cuckoo calls. Unfortunately, no one knows what happened to it after the Second World War. So far, no other organ manufacturer has been able to recreate this unique piece of work. The article is complemented by a short description of music performed in the “Słońce” cinema, particularly by the famous Poznań announcer Ludomir Budziński who performed under the alias — Szeliga.
Wpływ II wojny światowej na poszukiwanie rozwiązań prawnych w zakresie ochrony dóbr kultury
Authors: Stryjkowska Sylwia
Published: January 2022

Artykuł ukazuje zmiany, jakie nastąpiły w systemie prawnej ochrony dóbr kultury po zakończeniu II wojny światowej. Konflikt ten przyczynił się do bezprecedensowych strat w zasobach kulturowych, by następnie stać się punktem wyjścia do prac nad narzędziami prawnej ochrony dziedzictwa kulturalnego. Ukazując proces kształtowania się rozwiązań prawnych w tym zakresie, szczególną uwagę zwrócono na Konwencję w sprawie ochrony dóbr kultury w razie konfliktu zbrojnego podpisaną w 1954 r. w Hadze, która stanowiła pierwszy wymierny przejaw intensyfikacji współpracy międzynarodowej, jaka po II wojnie światowej nastąpiła w obszarze ochrony dóbr kultury. Uwagę poświęcono nadto metodom reparacyjnym służącym powetowaniu doznanych w konflikcie strat kulturalnych. The impact of the Second World War on the process of seeking legal solutions in the field of cultural property protection The article demonstrates changes chich occurred in the system of legal protection of cultural property after the Second World War. This conflict caused unprecedented cultural losses, and became the starting point for work on solutions aiming at legal protection of cultural heritage. The importance of the 1954 Hague Convention for the Protection of Cultural Property in the Event of Armed Conflict is particularly highlighted. The convention was the first concrete evidence of intensified international cooperation that occurred after the Second World War in the area of cultural property protection. The article also presents approaches to reparations for cultural losses sustained during the conflict.
з історії одного фальсифікату: привілей казимира ііі для панів із бжезя
Authors: Horbach Tymur
Published: January 2022

W niniejszym artykule omówiono kwestię autentyczności przywileju króla Kazimierza III dla Zbigniewa z Brzezia i jego rodziny z 7 września 1370. Dokument ten zawiera potwierdzenie wcześniejszego przywileju cesarza Karola IV dla Zbigniewa i jego brata Stanisława o nadaniu im tytułu hrabiów Rzeszy i herbu, oraz darowanie przez polskiego władcy synom Zbigniewa Przedborowi i Pakosławowi miasta Włodzisław. Podjęto próbę uzasadnić tezę, że dokonane na rzecz panów z Brzezia nadanie nie zostało skasowane przez Ludwika Węgierskiego, natomiast na nim został oparty sporządzony w połowie XVII wieku przez ks. S. Wojeńskiego falsyfikat bogatszego w treści przywileju królewskiego. Do artykułu dołączono tekst nieznanego dotychczas oryginału tego przywileju, który obecnie przechowuje się w zbiorach archiwum Instytutu rękopisu Biblioteki Narodowej im. Włodzimierza Wiernadskiego w Kijowie.

The story of one forgery: Casimir III ’s privilege for the landowners of Brzeź

The article discusses the issue of authenticity of a privilege granted by king Casimir III to Zbigniew of Brzeź and his family on September 7, 1370. The document confirms the earlier privilege granted by emperor Charles IV to Zbigniew and his brother Stanisław, giving them the title of counts of the Reich and a coat of arms, and also endows the sons of Zbigniew (Przedbor and Pakosław) with the Polish town of Włodzisław. The article provides evidence for the thesis that this bestowal was not canceled by Louis I of Hungary. The document was the basis for a much broader privilege, forged by father S. Wojeński in the mid-17th century. The article is supplemented by the previously unknown original text of the privilege, which is now part of the collection of the archive of the Institute of Manuscripts in the Vladimir Vernadsky National Library in Kyiv.
Approaches to Death and Dying: Bioethical and Cultural Perspectives
Authors: Piasecki Jan
Published: January 2022

The book Approaches to Death and Dying: Bioethical and Cultural Perspectives, edited by Marta Szabat and Jan Piasecki, is part of a still too narrow catalogue of works devoted to end-of-life themes. The volume consists of eleven articles arranged in four parts corresponding to a broad range of issues: law, ethics, philosophy, and cultural studies. The arrangement of the book is thus constructed around various perspectives upon which any reflection on death and dying must be based. This is perhaps indicative of how difficult it is to adopt an unambiguous attitude towards death–modernity, which introduces a multitude of possible choices and decisions regarding our own bodies, has enhanced individualism but at the same time done away with the order provided by old customs, cultural arrangements, strategies towards the inevitable and the power exerted by that order. Addressing the issue of death and dying in the suggested contexts conjures up a number of meanings and problems that require reflection and even solutions. I am delighted to say that I have no hesitation in recommending the publication of Approaches to Death and Dying: Bioethical and Cultural Perspectives, an impeccably edited volume of considerable intellectual substance. The book demonstrates the importance of collective works integrating the research of various scientific communities, provided, however, that the selection of both the topic and the writers is not governed by chance, but rather by a carefully thought-out and faultlessly explored idea of more general resonance. And this is the case here, for which congratulations and respect are deserved. I am convinced that this opinion will be shared by the readers of this publication.

A Lightweight Hardware Secure and Reliable Framework using Secure and Provable PUF for IoT Devices against the Machine Learning Attack
Authors: Annapurna K. Y. , Koppad Deepali
Published: January 2022

IoT (Internet of Things) has been expanding into various business activities and people’s lives; however, IoT devices face security challenges. Further, the establishment of reliable security for IoT constrained devices is considered to be ongoing research due to several factors such as device cost, implementation area, power consumption, and so on. In addition to these factors, hardware security also poses major challenges like above mentioned; further Physical Unclonable Functions (PUFs) offer a promising solution for the authentication of IoT devices as they provide unique fingerprints for the underlying devices through their challenge-response pairs. However, PUFs are vulnerable to modelling attacks; in this research work, a lightweight hardware security framework is designed that provides the security for light edge devices. The proposed hardware security framework introduces the three-step optimized approach to offer a secure and reliable solution for IoT device authentication. The first step deals with the designing of SP-PUF, the second step deals with introducing obfuscation technique into the same, and the third step deals with introducing the authentication mechanism. A machine learning attack is designed to evaluate the model and the proposed model is evaluated considering the different stages. This research work is evaluated in two parts; the first part of the evaluation is carried out for the security mechanism through machine learning algorithm attack i.e., logistic regression, Neural Network, and SVM; further evaluation is carried out considering the PUF evaluation parameter as uniqueness and reliability. At last, comparative analysis suggest that proposed hardware security framework is safe against the machine learning attacks and achieves high reliability and optimal uniqueness.

Authors: Rudiansyah Deden
Published: January 2022

Community Service is one of the Tri Dharma of Higher Education, especially at Garut University, it is hoped that with this community service the existence of universities can contribute to the development of scientific application to the community. In the current era of technology, which requires all small industry players to improve their abilities in the field of communication and information technology, currently internet-based technology creates a business environment that is no longer concerned with time and distance. The implementation of sales education through social media is a service to the community with the aim of helping the Sabilulungan Women's Farmers' Demplot Group to increase sales and income so that the Demplot Farmers' Group can survive in today's business competition. The activity method in community service uses a technique of delivering material verbally to the participants, this community service has a background problem because agricultural products from the Demonstration Farmer Group still sell conventional products and have not made good use of online sales using social media and e-commerce platforms. The results of the research carried out were able to innovate marketing which was originally conventional into marketing that utilizes technological developments, namely by conducting electronic marketing by utilizing social media and E-commerce platforms as sales media.
Mejoramiento de los tiempos de arribo y salida en un sistema de transporte público masivo aplicando un modelo computacional y Simulación Montecarlo
Authors: Cárdenas-Ruperti Jonathan P. , Padilla-Alvarez Luis A. , León-Santillan Olga L.
Published: January 2022

El presente trabajo tiene como objetivo simular el arribo y salida de las unidades de transporte para poder mejorar la calidad del servicio y el tiempo de espera que toma cada unidad de transporte público para realizar el recorrido completo aplicando el método de simulación de Montecarlo. Debido a la falta de buses para poder abastecer a toda la comunidad que utiliza este medio de transporte y las recientes quejas de los moradores debido a que no hay un bus que circule por ese lugar, se propondrá la adquisición de nuevas unidades, para cumplir esta demanda. En este proyecto se simula el tiempo de salida de los buses de la Cooperativa Albosau línea 47. Para poder realizar esta simulación, se utiliza una distribución uniforme, en la cual el tiempo medio de salida de cada bus va a ser tomado un viernes en la estación del bus. Para poder obtener el tiempo de espera entre cada salida de bus, se utiliza el Método de Montecarlo, en donde se genera números aleatorios en programa elaborado en Python, para de esta manera conocer el tiempo estimado del proceso y para saber si es conveniente adquirir unidades nuevas. Como resultado, se redujeron los tiempos promedios de llegada y salidas de los buses de esta cooperativa. Así mismo se pudo determinar, mediante una distribución uniforme, los tiempos promedios en cada uno de los procesos de salida y llegada de todos los buses, incluyendo los que ya cuenta la cooperativa de transporte.

This article is concerned with designing numerical schemes for the generalised Oskolkov equation using the quintic B-spline collocation finite element method. Applying the von-Neumann theory, it is shown that the proposed method is marginally unconditionally stable. It was obtained the theoretical bound of the error in the full discrete scheme for the first time in the literature. The accuracy and effectiveness of the method checked with three model problems, consisting of a single solitary wave, Gaussian initial condition and growth of an undular bore. The performance of the new method is demonstrated by calculating invariant I and error norms L2 and L∞. Results are displayed both numerically and graphically. Numerical experiments support the correctness and robustness of the method which can be further used for solving such problems.

Authors: OZEKEN CETIN CEMAL , CEVIK CUNEYT
Published: January 2022

In this paper we present a fixed point theorem for order-preserving Prešić type operators on ordered vector metric spaces. This result extends many results in the literature obtained for Prešić type operators both on metric spaces and partially ordered metric spaces. We also emphasize the relationships between our work and the previous ones in the literature. Finally we give an example showing the fact that neither results for Prešić type contractions on metric spaces nor the results for ordered Prešić type contractions on ordered metric space is applicable to it.

A range of nanostructured oxides with excellent properties is used in technology and science for applications in several fields: catalysis, gas detection, biomedical applications. The most studied forms of oxides are hematite, maghemite and magnetite. In this study, microwave-assisted hydrolytic synthesis and microwave-assisted coprecipitation synthesis are described for the preparation of undoped and doped iron oxide powders using iron (III) chloride (FeCl3), potassium chloride (KCl) as precursors and sodium hydroxide (NaOH) solution as a hydrolysis agent. Microwave-assisted hydrolysis was performed at different concentrations of FeCl3 precursor: 0.1 M, 0.4 M, 0.7 M to which a constant concentration of hydrolysis agent was added, and the synthesis to obtain potassium-doped powders consisted of co-precipitation of 0.1M FeCl3 and 0.025M KCl precursor solutions in the presence of 2M NaOH hydrolysis agent. The developed powders were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), and Fourier transform infrared spectroscopy (FTIR). The novelty is the use of potassium as a doping element for iron oxide, for potential application as catalyst. Hematite doped with 5% K was obtained by microwave-assisted coprecipitation synthesis. The presence of K was evidenced by EDS, while XRD spectra indicate successful doping of iron oxide with potassium, either interstitially or by substitution. By microwave synthesis, an increase in particle size was observed with increasing calcination temperature. The formation of the crystalline hematite phase was not obtained in the microwave heating process but following calcination of the powder

Background: Delivery Room Cuddles (DRC) is a growing practice with recognized benefits for parent-infant bonding, breastfeeding rates, and infant stress responses.
Methods: We introduced DRC at St. Mary’s NICU, Manchester, in October 2020. As part of a formal QI process, we have been continuously collecting data on all babies admitted to our NICU from the delivery suite to review rates of DRC and monitor for any beneficial effects / adverse events.
From October 2020 to May 2021, we admitted 41 babies with known surgical defects; 56% of whom had a DRC, including intubated babies with congenital diaphragmatic hernias, and babies with open surgical defects.
Results: There have been no adverse incidents directly related to DRC and more babies who had a DRC received breast milk than those who did not
Conclusion: Our study demonstrates that DRC can be implemented safely in surgical babies.

Vonoprozan: potentially new first-line treatment for delayed upper gastrointestinal bleeds following endoscopic procedures? A letter to the editor
Authors: Muhammad Umer  , Syed Wasif Bukhari
Published: January 2022

Endoscopy nowadays is widely used as a diagnostic and therapeutic tool for various gastrointestinal diseases due to it being less invasive and safer. However, amongst some adverse events is delayed bleeding. The definition of delayed bleeding requires endoscopic hemostasis and/or blood transfusion after at least two days of treatment. (1)
Oesophageal cancer is comparatively more common in Pakistan, being 7th most common malignancy in men and 6th most common in women in Karachi. (2) Oesophageal endoscopic submucosal dissection (E-ESD) employed in the treatment of the above- mentioned cancer has an incidence of delayed bleeding of about 1.3-6.7%. (1) The prevalence of gastric cancer across Pakistan was about 2-18% (3), for which endoscopic submucosal dissection is often used has an incidence of delayed bleeding of 4.7-15.6%. (1) Endoscopic therapy for gastroesophageal varices can also result in delayed bleeding, the incidence of which easily reaches up to 10%. (1)
In a retrospective cohort study of 124,422 patients conducted in Japan, it was found that vonoprazan was more effective in reducing the risk of delayed bleeding compared to omeprazole. (OR= 0.75) (1) Vonoprazan works by competitively inhibiting the potassium-acid channel resulting in strong and sustained acid inhibition. (4) It was also found to have a superior effect in the eradication of H Pylori and an equal effect in acid-related disorders. (5)
 In the retrospective study mentioned above, it is also worth noting that the efficacy of vonoprazan was variable with respect to procedures and was most prominent with gastroduodenal endoscopic submucosal dissection (OR=0.70). (1) Other procedures did not elicit any significant difference. In addition, standard/high dose vonoprazan proved to be most efficacious in reducing the risk of delayed bleeding compared with standard/high-dose PPI and low-dose vonoprazan. It was also observed that patients taking anti-thrombotic medications at a higher risk of delayed bleeding also benefited from high-dose vonoprazan. (OR=0.74) (1) The findings above compel the conclusion that high dose vonoprazan should be ideal for reducing the risk of delayed bleeding in patients who have undergone gastroduodenal endoscopic submucosal dissection and/or are on anti-thrombotics.
Though high-dose vonoprazan does look promising, it is imperative that more randomized controlled trials on more diverse populations be conducted to further explore its efficacy and safety as the drug might be a potential first line of therapy.
