Diagnostic tools for fecal incontinence: Scoring systems are the crucial first step
Authors: Liptak Peter , Duricek Martin , Banovcin Peter
Published: February 2024

The main aim of this editorial is to comment on the recent article published by Garg et al in the World Journal of Gastroenterology 2023; 29: 4593-4603. This original research presents a new scoring system for fecal incontinence. Fecal incontinence is a chronic disease with a severe impact on the quality of life of the patients. Substantial social stigmatization often leads to significant underreporting of the condition even during visits to a specialist and could lead to further mismanagement or non-existent management of the disease. An important fact is that patients are often unable to describe their condition when not asked precisely defined questions. This problem is partially resolved by scoring questionnaires. Several scoring systems are commonly used; however, each of them has their shortcomings. For example, the absence of different kinds of leakage besides flatus and stool could further lead to underscoring the incontinence severity. Therefore, there has long been a call for a more precise scoring system. The correct identification of the presence and severity of fecal incontinence is paramount for further diagnostic approach and for choosing the appropriate therapy option. This editorial describes fecal incontinence, its effect on quality of life in general and further evaluates the diagnostic approach with a particular focus on symptom scoring systems and their implications for clinical practice.
Unmet needs in biomarkers for autoimmune pancreatitis diagnosis
Authors: Wang Bao-Can , Fan Jian-Gao
Published: February 2024

Autoimmune pancreatitis (AIP) is a rare chronic autoimmune disorder. The diagnosis of AIP mainly depends on histopathology, imaging and response to treatment. Serum immunoglobulin 4 (IgG4) is used only as collateral evidence in diagnostic criteria for AIP because of its moderate sensitivity. Serum IgG4 levels are normal in 15%-37% of type 1 AIP and most of type 2 AIP patients. In these patients, the indeterminate imaging and histopathology may lead to the difficulty in definitive diagnosis of AIP. Therefore, discovery of new biomarkers is important for AIP diagnosis. Here, we provide some views on the progression and challenges in identifying novel serological biomarkers in AIP diagnosis.
Emerging role of exosomes in ulcerative colitis: Targeting NOD-like receptor family pyrin domain containing 3 inflammasome
Authors: Li Xin , Ji Li-Jiang , Feng Kai-Di , Huang Hua , Liang Mei-Rou , Cheng Shi-Jin , Meng Xiu-Dong
Published: February 2024

Ulcerative colitis (UC) is a chronic recurrent inflammatory bowel disease. Despite ongoing advances in our understanding of UC, its pathogenesis is yet unelucidated, underscoring the urgent need for novel treatment strategies for patients with UC. Exosomes are nanoscale membrane particles that mediate intercellular communication by carrying various bioactive molecules, such as proteins, RNAs, DNA, and metabolites. The NOD-like receptor family pyrin domain containing 3 (NLRP3) inflammasome is a cytosolic tripartite protein complex whose activation induces the maturation and secretion of proinflammatory cytokines interleukin-1β (IL-1β) and IL-18, triggering the inflammatory response to a pathogenic agent or injury. Growing evidence suggests that exosomes are new modulators of the NLRP3 inflammasome, with vital roles in the pathological process of UC. Here, recent evidence is reviewed on the role of exosomes and NLRP3 inflammasome in UC. First, the dual role of exosomes on NLRP3 inflammasome and the effect of NLRP3 inflammasome on exosome secretion are summarized. Finally, an outlook on the directions of exosome-NLRP3 inflammasome crosstalk research in the context of UC is proposed and areas of further research on this topic are highlighted.
Optimized sequential therapy vs 10- and 14-d concomitant therapy for eradicating Helicobacter pylori: A randomized clinical trial
Authors: Seddik Hassan , Benass Jihane , Berrag Sanaa , Sair Asmae , Berraida Reda , Boutallaka Hanae
Published: February 2024

BACKGROUND

A cure for Helicobacter pylori (H. pylori ) remains a problem of global concern. The prevalence of antimicrobial resistance is widely rising and becoming a challenging issue worldwide. Optimizing sequential therapy seems to be one of the most attractive strategies in terms of efficacy, tolerability and cost. The most common sequential therapy consists of a dual therapy [proton-pump inhibitors (PPIs) and amoxicillin] for the first period (5 to 7 d), followed by a triple therapy for the second period (PPI, clarithromycin and metronidazole). PPIs play a key role in maintaining a gastric pH at a level that allows an optimal efficacy of antibiotics, hence the idea of using new generation molecules.

AIM

To compare an optimized sequential therapy with the standard non-bismuth quadruple therapies of 10 and 14 d, in terms of efficacy, incidence of adverse effects (AEs) and cost.

METHODS

This open-label prospective study randomized 328 patients with confirmed H. pylori infection into three groups (1:1:1): The first group received quadruple therapy consisting of twice-daily (bid) omeprazole 20 mg, amoxicillin 1 g, clarithromycin 500 mg and metronidazole 500 mg for 10 d (QT-10), the second group received a 14 d quadruple therapy following the same regimen (QT-14), and the third group received an optimized sequential therapy consisting of bid rabeprazole 20 mg plus amoxicillin 1 g for 7 d, followed by bid rabeprazole 20 mg, clarithromycin 500 mg and metronidazole 500 mg for the next 7 d (OST-14). AEs were recorded throughout the study, and the H. pylori eradication rate was determined 4 to 6 wk after the end of treatment, using the 13C urea breath test.

RESULTS

In the intention-to-treat and per-protocol analysis, the eradication rate was higher in the OST-14 group compared to the QT-10 group: (93.5%, 85.5% P = 0.04) and (96.2%, 89.5% P = 0.03) respectively. However, there was no statistically significant difference in eradication rates between the OST-14 and QT-14 groups: (93.5%, 91.8% P = 0.34) and (96.2%, 94.4% P = 0.35), respectively. The overall incidence of AEs was significantly lower in the OST-14 group (P = 0.01). Furthermore, OST-14 was the most cost-effective among the three groups.

CONCLUSION

The optimized 14-d sequential therapy is a safe and effective alternative. Its eradication rate is comparable to that of the 14-d concomitant therapy while causing fewer AEs and allowing a gain in terms of cost.

Authors: Wang Wen-Peng , Shi Dan , Yun Duo , Hu Jun , Wang Jie-Fu , Liu Jia , Yang Yan-Peng , Li Ming-Rui , Wang Jun-Feng , Kong Da-Lu
Published: February 2024

BACKGROUND

Esophageal squamous cell carcinoma (ESCC) is a deadly malignancy with limited treatment options. Deubiquitinases (DUBs) have been confirmed to play a crucial role in the development of malignant tumors. JOSD2 is a DUB involved in controlling protein deubiquitination and influencing critical cellular processes in cancer.

AIM

To investigate the impact of JOSD2 on the progression of ESCC.

METHODS

Bioinformatic analyses were employed to explore the expression, prognosis, and enriched pathways associated with JOSD2 in ESCC. Lentiviral transduction was utilized to manipulate JOSD2 expression in ESCC cell lines (KYSE30 and KYSE150). Functional assays, including cell proliferation, colony formation, drug sensitivity, migration, and invasion, were performed, revealing the impact of JOSD2 on ESCC cell lines. JOSD2's role in xenograft tumor growth and drug sensitivity in vivo was also assessed. The proteins that interacted with JOSD2 were identified using mass spectrometry.

RESULTS

Preliminary research indicated that JOSD2 was highly expressed in ESCC tissues, which was associated with poor prognosis. Further analysis demonstrated that JOSD2 was upregulated in ESCC cell lines compared to normal esophageal cells. JOSD2 knockdown inhibited ESCC cell activity, including proliferation and colony-forming ability. Moreover, JOSD2 knockdown decreased the drug resistance and migration of ESCC cells, while JOSD2 overexpression enhanced these phenotypes. In vivo xenograft assays further confirmed that JOSD2 promoted tumor proliferation and drug resistance in ESCC. Mechanistically, JOSD2 appears to activate the MAPK/ERK and PI3K/AKT signaling pathways. Mass spectrometry was used to identify crucial substrate proteins that interact with JOSD2, which identified the four primary proteins that bind to JOSD2, namely USP47, IGKV2D-29, HSP90AB1, and PRMT5.

CONCLUSION

JOSD2 plays a crucial role in enhancing the proliferation, migration, and drug resistance of ESCC, suggesting that JOSD2 is a potential therapeutic target in ESCC.

Pain is an individual experience that is affected by psychological, social and physical factors and should be treated as a pathology in itself. Low back pain is a mechanical pain located in the lumbar region and gluteal fold, which may or may not generate stiffness and consequently reduced functionality. Lumbosciatalgia, on the other hand, is when this pain and discomfort radiates to the limb, to one or two buttocks and/or to the posterior region of the thigh. This study is a literature review, with searches in the following databases: PubMed, Lilacs and Scielo, using descriptors such as "low back pain", "physical training", "strength training" and "low back pain". Low back pain is one of the most common causes of disability in modern society, with a prevalence of 60-85%; it is the second leading cause of seeking medical attention.Strength training and core stability improves the balance and endurance of the lumbar muscles, as well as activating the deeper muscle groups, reinforcing the fixity of the spine and reducing the stimulation of pain receptors in the tissues. This is why free weight training with higher intensity loads, or not, provides wide-ranging benefits for prevention and improved quality of life due to significant reductions in pain, improved posture, flexibility and strength endurance.
Self-Concept and its Components for Developing Research in Positive Psychology: An Integrative Model
Authors: Elsherif Khaled
Published: February 2024

The study aimed to reduce researchers’ suffering from the abundance and diversity of psychological and educational research that deals with self-concept and its components. The challenge with starting from different theoretical frameworks is that this reflects negatively on the results and variables associated with each component. There are also many self-components, combined with the synonymy of some names, that confuse researchers and place research in the cycle of stereotyping and repetition. Therefore, presenting a graphical form that includes a description of the self-concept components and clarifies the relationships between them and their role in the structure of the human self contributes to solving this problem. In the theoretical framework, the theoretical concepts of the components were reviewed, and the method for developing integrated models that aim to transfer self-concept research in psychology from the level of description to the level of analysis was explained by taking advantage of the huge number of empirical studies on the self. A questionnaire consisting of four dimensions, including 40 items, was applied to a sample of 12 psychology experts. The results indicated that the self-concept serves as a basis for an integrated model of the self-components. The spatial analogy method was used in developing the model inputs, processes, and outputs. The sub-components that are closest in relationship to the self-concept are self-image, self-esteem, and the ideal self in the operations stage. The next closest variables are self-regulation, self-affirmation, self-actualization, and self-compassion. The model explains each in detail, and a set of recommendations and proposals were produced.

Phase Shift Modulation Strategy for Single Stage AC to DC Dual Active Bridge Converter
Authors: Faiz Ahmed Maha , N. Abdul Kadir Mohamad
Published: February 2024

Energy exchange between AC grid and DC supply that is a part of a hybrid electric micro-grid takes place using various power converter designs. The single-phase, single-stage, AC-DC power dual active bridge converter is one option. The phase-shift modulation is used to regulate energy flow in both directions. The topology of one stage AC-DC dual active bridge converter based in bidirectional switching modules has been introduced. This paper next introduces the analysis of the AC side current considering basic modulation functions and suggests an optimum phase-shifted modulation strategy. The proposed modulation function provides minimum harmonics distortion. A simulation study is presented to compare the proposed strategy to the basic sinusoidal and triangular modulation techniques. The results show that the modified modulation reduces the average THD by about 55% and 39% compared to the standard sinusoidal and triangular modulation strategies respectively and ensures linear relationship between the transferred power and magnitude control coefficient.

Licheniformis VKM B-3172D, inactivated biomass of the fungus R. citrinum VKM B-4930D on the indicators of digestibility, digestibility and zootechnical indicators in pigs on rearing. The study was carried out on 15 heads of local hogs (F1:(DxL) during the fattening period with an initial live weight of 20‒25 kg at the age of 45 days. The duration of the study is 45 days. The inclusion of a probiotic additive inactivated biomass of the mushroom in the composition of full-fledged compound feeds of experimental groups of growing fattened young pigs. "Cytosporin" provide an increase in average daily live weight gain by 0.79‒3.6% compared to control animals. In growing young pigs of experimental groups that received the studied probiotic additives, the coefficient of digestibility of dry matter increased by 0.24–2.4%, organic matter – by 0.6–1.27%, protein – by 0.17‒2.34% compared to control animals.

Erysipelas of pigs (Erysipelothrix rhusiopathiae) is a widespread natural focal, septic, infectious disease, which occurs both acutely and chronically in the form of epizootic outbreaks. The microorganism is a stationary, straight or slightly curved stick of small size, gram-positive, not forming spores and capsules. At the moment, more than 10 strains and about 30 serotypes are known, more than 80% of the identified isolates belong to serovars 1 or 2, the microorganism is highly resistant to environmental factors and rotting, and specific serological identification of the pathogen is carried out using an agglutination reaction. Considering the problem in more detail, it can be noted that not everything is as simple as it seems at first glance, recently foreign colleagues have made much more progress in this issue than domestic ones. According to foreign literature, from 30% to 50% of pigs are carriers of a latent form of the disease. Erysipelas outbreaks can cause a high degree of morbidity and mortality within a few days, young animals are more susceptible to erysipelas, 3–12 months old, in the maintenance of which a large amount of financial and labor resources is invested.
Ilektra Apostolou: A Greek female resistance fighter and a heroine of the left
Authors: Chatzitheodorou Christina
Published: February 2024

The Greek resistance fighter Ilektra Apostolou was executed on 26 July 1944, by the collaborationist security forces in Greece during the Second World War. Apostolou was a member of Kommounistiko Komma Ellados (KKE, Communist Party of Greece) and of Eniaia Panneladiki Organosi
Newn (EPON, United Panhellenic Organisation of Youth), and was involved in pre-war antifascist action. During the resistance, she tried to pass on the mentality she had developed from this early involvement to young women in EPON and Lefteri Nea (LT, Free Young Woman): that women
would be liberated only by actively participating in social struggles. Her biography is examined with a critical eye, taking into consideration that it was largely written after the war. This means that it not only provides a factual representation of Apostolou: it also functions as a lieu
de memoire, a site of memory. The politics of memory influences how her biography is constructed. The second part focuses on the memorialisation of Apostolou, examining it through the lens of intersectionality. Identity criteria – such as gender, race, age and political identification
– and the changing relative significance attributed to them are important both for shaping and understanding, memorialisa- tion processes. An intersectional approach seeks to reveal the hidden dimensions behind the memorialisation process. The last part focuses on Apostolou's post-war
legacy and explores how her memorialisation was intertwined with political developments from 1944 to the present, with a particular focus on the contestation over Apostolou's memory between the right and the left at various points in modern Greek history. The article draws on a combination
of secondary and primary sources, the main primary sources being those found in the Educational Centre of Charilaos Florakis (Archive of the Greek Communist Party) and the Contemporary Social History Archives (ASKI).
At the crossroads of race and gender during the Spanish Civil War
Authors: Everly Kathryn A.
Published: February 2024

Salaria Kea, the only African American nurse to serve during the Spanish Civil War, fought against racism and fascism her entire life. Her contributions during the war in Spain, as well as her legacy, have become complicated matters, as the veracity of her testimony found in archival
materials is routinely questioned and at times blatantly negated. Kea's experience as an African American woman positions her at the crossroads of racial and gender hierarchies that mark her identity in complex ways. Through the lens of various theories of intersectionality, this article will
grapple with the precarious modes of historical discourse found in the archive, and vindicate Kea's testimony, recognising it as making a crucial contribution – from a unique perspective – to the understanding of a more nuanced historical picture.
The many lives of writer Jef Last (1898-1972) Anti-fascist, socialist, humanist and gay rights activist
Authors: Wester Rudi , Weesjes With Elke
Published: February 2024

Writer, poet, painter, journalist, translator and compelling speaker: Jef Last roamed the globe, fought in the Spanish Civil War, joined the Dutch resistance during the Nazi occupation, and became an outspoken gay rights activist during and after World War II. His political journey
started in 1917 when he joined the Social Democratic Workers Party. From there he had brief yet tumultuous stints in the Revolutionary Socialist Party of Henk Sneevliet and the Dutch Communist Party. Disappointed with socialism and the Soviet Union, he identified as a humanist in later life.
Last was controversial yet appealing, and both selfish and selfless. Difficult to categorise, Last insisted on the indivisibility of his identity and experiences as an antifas- cist fighter and a gay man. This biographical article explores the many social identities of Jef Last.
Resisting fascism: The Argentine Junta de la Victoria and its president, 1941-1955
Authors: McGee Sandra
Published: February 2024

Created in 1941, the Junta de la Victoria (Victory Board, JV) was a Popular Front movement that supplied the Allies. It attracted about 45,000 diverse women throughout Argentina. The JV challenged local fascism by modelling a genuine democracy based on pluralism, intersectional solidarity,
freedom, and women's political incorporation. Members created ties across social differences. The JV's promotion of multiculturalism facilitated a shift from the Argentine ideal of a melting pot to one of ethnic diversity. Its president, Ana Rosa Schlieper, seemed an unlikely resistance fighter.
Initially her main identities were those of wife, philanthropist, and upper-class socialite. Her whiteness, beauty, and charm enhanced her prestige. In the mid-1930s Schlieper added antifascist and feminist to her intertwined identities. Seizing power in 1943, military officers suppressed
the JV, seeing it as a communist organisation. Some Argentine and U. S. officials accused Schlieper of being a communist dupe, although she was loyal to the democratic centrist Radical party. Under populist president Juan Perón (1946-1955), her class and political identities became
liabilities. Peronist hegemony and fear of being identified with an anti-Peronist and leftist group obliterated the public memory of Schlieper and the JV until recently.
On modeling arterial blood flow with or without solute transport and in presence of atherosclerosis
Authors: Riahi Daniel N. , Orizaga Saulo
Published: February 2024

In this article, we review previous studies of modeling problems for blood flow with or without transport of a solute in a section of arterial blood flow and in the presence of atherosclerosis. Moreover, we review problems of bio-fluid dynamics within the field of biophysics. In most modeling cases, the presence of red blood cells in the plasma is taken into account either by using a two-phase flow approach, where blood plasma is considered as one phase and red blood cells are counted as another phase, or by using a variable viscosity formula that accounts for the amount of hematocrit within the blood. Both analytical and computational methods were implemented to solve the governing equations for blood flow in the presence of solute transport, which, depending on the type of the investigated problem, could contain momentum, mass conservation, and solute concentration, which were mostly subjected to reasonable approximations. The form of atherosclerosis implemented in the modeling system either was either based on the experimental data for an actual human or was due to a reasonable mathematical modeling for both steady and unsteady atherosclerosis cases. For the wall of the artery itself, which is elastic in nature, modeling equations for the displacement of the artery wall has previously been used, even though their effects on the blood flow inside the artery were shown to be rather small. In some cases, thermal effects were also taken into account by including a temperature equation in the investigation. In the case of the presence of solutes in the blood, various blood flow parameters such as blood pressure force, blood speed, and solute transport were mostly determined or approximated for different values of the parameters that could represent hematocrit, solute diffusion, atherosclerosis height, solute reaction, and pulse frequency. In some studies, available experimental results and data were used in the modeling system that resulted in a more realistic outcome for the blood flow parameters, such as blood pressure force and blood flow resistance. Results have been found for variations of blood flow parameters and solute transport when compared to different values of the parameters. Effects that can increase or decrease the blood flow parameters and solute transport in the artery have mostly been determined, with particular applications for further understanding efforts to improve the patients' health care.
Multi-cloud resource scheduling intelligent system with endogenous security
Authors: Cai Nishui , He Guofeng
Published: February 2024

A secure and reliable intelligent multi-cloud resource scheduling system in cyberspace is especially important in some industry applications. However, this task has become exceedingly challenging due to the intricate nature of information, the variety of knowledge representations, the compatibility of diverse knowledge reasoning engines, and the numerous security threats found in cloud networks. In this paper, we applied the endogenous security theory to the multi-cloud resource scheduling intelligent system and presented a novel model of the system. The proposed model incorporates various knowledge representations and inference engines, resulting in a multi-cloud resource scheduling intelligent system that ensures endogenous security. In addition, we have devised a scheme for an intelligent system that schedules multi-cloud resources using dual-channels and has an endogenous security mechanism, which we have named Dynamic, Heterogeneous, and Redundant (DHR). Finally, we have used the multi-cloud resource scheduling intelligent run log database to carry out numerous experiments to validate the efficiency of the dual-channel redundant reasoning system with the endogenous security mechanism's DHR property. The results of the experiment demonstrated that the multi-cloud resource intelligent scheduling system model with an endogenous security mechanism was superior to the current single-channel inference system scheme in regards to security and reliability.
