"As this is a editorial article, it has got no sections of methods, results, tables, biostatistics, units and ethical statement to provide commentary on these sections. The editorial by Behrens and Elgafy provides an insightful analysis of factors influencing outcomes in indirect decompression through oblique and lateral lumbar interbody fusions (OLIF and LLIF). The discussion on patient selection criteria, particularly regarding preoperative spinal canal dimensions and lateral recess depth, is a valuable contribution to clinical decision-making. The emphasis on the unpredictability of outcomes in patients with severe lateral recess stenosis and the potential need for staged procedures highlights a crucial consideration for spine surgeons. However, one area that could benefit from further exploration is the long-term stability of indirect decompression compared to direct decompression, especially concerning adjacent segment disease and fusion longevity. Additionally, a deeper comparison of OLIF and LLIF in terms of specific complications and recovery trajectories would provide even greater clinical relevance. Overall, this editorial offers a comprehensive and well-referenced synthesis of the current literature on indirect decompression. It serves as a useful guide for surgeons considering minimally invasive approaches while remaining cautious about their limitations."

"The clinical significance of this study lies in its innovative approach to predicting colorectal polyp recurrence using machine learning (ML), specifically the eXtreme Gradient Boosting (XGBoost) model. Colorectal cancer (CRC) remains a leading cause of cancer-related mortality worldwide, largely preventable through early detection and effective management of precancerous polyps. Endoscopic mucosal resection (EMR) is widely utilized for the removal of colorectal polyps, yet it carries a considerable risk of recurrence, highlighting the need for accurate predictive tools to guide postoperative surveillance. This study identifies critical independent risk factors for polyp recurrence one year post-EMR, such as age, family history, smoking habits, diarrhea, Helicobacter pylori infection, polyp size, number of polyps, and hazard classification. By leveraging ML algorithms, particularly XGBoost, the researchers have developed a model with superior predictive performance, evidenced by high Area Under the Curve (AUC) values exceeding 0.90 across multiple validation cohorts, including a prospective validation set, indicating robust predictive accuracy and clinical utility. Clinically, the XGBoost model offers substantial advantages. Its high sensitivity, specificity, accuracy, precision, and F1 scores suggest that it effectively stratifies patients based on recurrence risk. Such a model significantly enhances personalized patient management by informing more accurate follow-up intervals, potentially improving patient outcomes through timely interventions and reducing unnecessary colonoscopies in low-risk individuals. Additionally, the authors' development of an accessible online web calculator based on this predictive model further underscores its practical utility in routine clinical practice. Clinicians can conveniently input patient-specific clinical parameters to obtain immediate, individualized risk predictions, facilitating shared decision-making between physicians and patients. Decision Curve Analysis further underscores the practical value of this tool, demonstrating that using the XGBoost model provides superior clinical net benefit compared to standard follow-up strategies. This methodical approach not only advances clinical decision-making but also optimizes healthcare resources by prioritizing surveillance for those most at risk. Finally, the interpretability of the model via SHapley Additive exPlanations (SHAP) analysis significantly mitigates concerns about the "black box" nature commonly associated with ML models, thus increasing clinician trust and acceptability. In conclusion, this ML-based predictive model represents a critical advancement in clinical gastroenterology, providing robust, data-driven support for clinicians in making individualized recommendations for colorectal polyp surveillance and potentially reducing colorectal cancer incidence through targeted early intervention."

"We greatly appreciate the authors and their team for their in-depth study on treatment strategies for rectal neuroendocrine neoplasms (R-NENs). This retrospective analysis compares the efficacy of endoscopic full-thickness resection (EFTR) and endoscopic submucosal dissection (ESD) in the treatment of R-NENs, demonstrating the superior R0 resection rate of EFTR while maintaining comparable short-term safety with ESD. This study provides critical clinical evidence supporting the use of EFTR in R-NENs and contributes to the refinement of function-preserving surgical approaches. However, we would like to offer some constructive suggestions to enhance the clinical applicability and long-term evaluation of this study. First, some terminology and definitions in the study are somewhat ambiguous, which may affect the interpretability of the results. For instance, the study mentions that some patients had "severe comorbidities" but does not specify the types of comorbidities or the inclusion/exclusion criteria applied. Certain comorbidities, such as diabetes or chronic kidney disease, may impact postoperative healing, and failing to differentiate them could introduce confounding among patients with varying risk profiles. Additionally, the description of lesion morphology is inherently subjective, and the study does not clarify whether standardized imaging assessments, such as endoscopic ultrasound (EUS), were used to measure lesion size and invasion depth. Inconsistencies in preoperative evaluation criteria could lead to bias in treatment selection. For example, was EFTR preferentially chosen for lesions with specific morphological characteristics? Future studies should adopt more detailed imaging assessment criteria and pathological grading methods to improve reproducibility and the interpretability of results. Second, the study does not assess the impact of the learning curve for EFTR and ESD on surgical outcomes. As a relatively novel technique, EFTR may require a longer period of experience accumulation to achieve stable performance. The study does not clarify whether operator experience was comparable between the EFTR and ESD groups or whether surgical success rates varied with increasing experience. If EFTR procedures were performed by highly experienced endoscopists while ESD procedures involved a broader range of operators, the results could be biased in favor of EFTR. Additionally, since EFTR has a steeper learning curve, factors such as procedure time and complication rates may decrease with increased experience, but the study does not conduct a dynamic analysis of these trends. Future studies should incorporate learning curve analyses to evaluate the influence of experience on surgical outcomes, ensuring a fair comparison between the two techniques. Furthermore, EFTR may cause greater bowel wall injury than ESD, potentially affecting postoperative bowel function, yet this study focuses primarily on R0 resection rates and short-term complications without assessing long-term functional outcomes. As a full-thickness resection technique, EFTR may alter rectal compliance, bowel movement frequency, and gut motility. However, the study does not provide data on postoperative bowel function changes, alterations in defecation patterns, bloating, or incontinence. If EFTR improves R0 resection rates but increases the risk of postoperative functional impairment, its clinical utility must be considered more cautiously. Future research should incorporate patient-reported outcomes (PROs) and quality of life (QoL) assessments and include long-term functional evaluations such as anorectal manometry and bowel dysfunction scoring to comprehensively assess the impact of EFTR on patient prognosis."

"Stem Cell Therapy: A New Hope for Patients with Skeletal Muscle Atrophy? Skeletal muscle atrophy refers to the reduction or loss of muscle fibers due to nutritional deficiencies or diseases, leading to a decline in muscle mass. Current studies indicate that skeletal muscle atrophy is closely associated with an imbalance between protein synthesis and degradation, driven by multiple factors such as inflammation, oxidative stress, autophagy, and apoptosis [1-3]. Due to the complexity of its molecular mechanisms, effective therapeutic strategies are lacking, and traditional approaches like rehabilitation training and pharmacological interventions show limited efficacy. Therefore, exploring more effective treatments is imperative. Stem cell therapy, with its unique regenerative potential and immunomodulatory properties, offers a promising avenue for treating this condition. In the current issue of the World Journal of Stem Cells, Ying-Jie Wang and colleagues published a review titled "Stem Cell Therapy: A Promising Therapeutic Approach for Skeletal Muscle Atrophy." The article summarizes the molecular mechanisms of muscle atrophy and highlights the applications of mesenchymal stem cells (MSCs), induced pluripotent stem cells (iPSCs), and their derivatives (e.g., exosomes) in treating skeletal muscle atrophy. These stem cells exert therapeutic effects by modulating inflammation, promoting angiogenesis, suppressing oxidative stress, and facilitating muscle regeneration. The authors also address challenges in clinical translation, including immune rejection, tumorigenic risks, inefficient stem cell homing, and the absence of standardized protocols. Despite these hurdles, the review expresses optimism about the future of stem cell therapy, particularly emphasizing the superior potential of stem cell-derived acellular therapies (e.g., exosomes) over traditional cell transplantation. We maintain a cautiously optimistic view regarding the prospects of stem cell therapy for skeletal muscle atrophy. While stem cell-based approaches, especially MSC- and exosome-based strategies, demonstrate promising safety and efficacy [4, 5], several issues must be resolved. These include addressing heterogeneity in stem cell sources, ensuring long-term safety, and establishing standardized protocols for clinical translation. Although iPSCs circumvent ethical concerns, their differentiation and purification techniques require optimization, and potential genetic mutations remain a concern. Exosomes, as acellular therapeutics, may reduce immune reactions; however, challenges in large-scale production and quality control persist. Therapeutic Potential of Stem Cells Stem cell therapy exhibits multidimensional potential in treating muscle atrophy. First, its mechanisms are highly synergistic: MSCs and iPSCs improve the muscle microenvironment by regulating inflammatory cytokines (e.g., suppressing IL-6 and TNF-α), promoting angiogenesis, inhibiting oxidative stress, and enhancing autophagy. Exosomes further amplify therapeutic effects by delivering functional miRNAs (e.g., miR-132-3p/FoxO3 axis) to delay protein degradation and stimulate regeneration [4, 6]. Second, exosomes as acellular carriers broaden clinical applicability: MSC-derived exosomes (e.g., hUC-MSC-Exos, ADSC-Exos) avoid immune rejection and tumorigenic risks associated with live cell transplantation. Their high biocompatibility and cargo of bioactive molecules (e.g., circHIPK3, AMPK/ULK1 regulators) enable targeted intervention in diabetes- or neuropathy-related atrophy, positioning them as pivotal tools for clinical translation [6, 7]. Third, iPSCs hold exceptional promise for personalized medicine. Their ability to differentiate into myogenic progenitor cells (MPCs) or motor neurons facilitates the reconstruction of neuromuscular junctions, offering precise repair for genetic atrophy (e.g., facioscapulohumeral muscular dystrophy, FSHD). While autologous iPSCs mitigate immune rejection, clinical application demands improved differentiation efficiency and safety [8, 9]. Current Challenges and Solutions Clinical translation of stem cell therapy faces multiple challenges requiring innovative solutions. First, heterogeneity and standardization: MSC efficacy varies with donor age, tissue source (e.g., bone marrow, adipose, umbilical cord), and culture conditions [10]. Establishing unified quality control standards—via surface marker screening, secretome profiling, and single-cell sequencing—is critical to identify functional subpopulations and enable precision manufacturing [11]. Second, genetic instability and differentiation inefficiency hinder iPSC applications: reprogramming-induced mutations and inconsistent differentiation protocols (transgene-dependent or -independent) limit reliability [12]. Integrating non-integrative methods (e.g., mRNA reprogramming) and 3D organoid culture systems may optimize differentiation pathways [8]. Third, exosome scalability and targeting: natural exosomes suffer from low bioactive content and short half-lives. Engineering strategies (e.g., ligand modification or drug loading) can enhance tissue-specific delivery [13, 14], while microfluidic-nanocarrier systems may resolve production bottlenecks. Finally, accelerating clinical translation: preclinical studies predominantly rely on animal models; multicenter trials are needed to validate long-term safety (e.g., tumorigenicity, immune tolerance) [15, 16]. Combining stem cell therapy with anti-inflammatory agents (e.g., IL-1β inhibitors), rehabilitation, or gene editing (e.g., CRISPR-Cas9) may synergistically enhance efficacy [17, 18]. Future Directions Future research should prioritize interdisciplinary integration and precision strategies. First, mechanistic insights: single-cell and spatial transcriptomics can unravel dynamic interactions between stem cells and the muscle microenvironment (e.g., satellite cells, macrophages), identifying key regulatory nodes (e.g., Wnt/β-catenin, PI3K/Akt pathways) [3, 19]. Second, biomaterial innovations: smart hydrogels or electroconductive scaffolds combined with localized stem cell/exosome delivery systems could enhance homing efficiency and functional persistence [20, 21]. Third, personalized approaches: tailored therapies based on disease-specific etiologies (e.g., ALS, diabetic atrophy) and molecular subtypes (e.g., inflammatory signatures) are essential. For instance, AMPK-activated umbilical cord MSCs may rectify metabolic dysregulation in diabetic atrophy [22, 23]. Lastly, ethical and regulatory frameworks: international guidelines must standardize stem cell therapies and clarify regulatory classifications (e.g., exosomes as "drugs") to accelerate clinical translation. Stem cell therapy for skeletal muscle atrophy is transitioning from bench to bedside, yet critical hurdles—standardization, safety, and efficacy validation—remain. Integrating multidisciplinary technologies (e.g., synthetic biology, bioinformatics) and advancing translational research will bridge the gap between "laboratory breakthroughs" and "patient benefits."

"Top-down therapy for Crohn's disease (CD) involves starting with the most potent medications, such as biologics and immunomodulators, immediately after early diagnosis. This strategy may lead to rapid induction of remission, promotion of mucosal healing, prevention of complications, and reduced need for surgery. However, the background factors influencing this top-down therapy have not been sufficiently examined. A recent report on a Japanese cohort found that factors significantly associated with the recent top-down treatment approach were male gender, perianal lesions, no immunomodulators, and anti-tumor necrosis factor therapy. (Miyoshi J, Yoon A, Matsuura M, Hisamatsu T. Real-world use of biologics during the first year of treatment for newly diagnosed Crohn's disease in Japan: a claims analysis from 2010 to 2021. Intest Res. 2025 [PMID: 39848334 DOI: 10.5217/ir.2024.00082]) Top-down therapy for CD should be considered case-by-case, weighing potential benefits against risks and costs. As the authors suggest, identifying patients with a high genetic predisposition for CD may help predict their response to medications, the risk of side effects, and the cost-effectiveness. Further investigation in this area is desirable. "

"This review presents a comprehensive analysis of the role of Traditional Chinese Medicine (TCM) in the treatment of chronic atrophic gastritis (CAG), highlighting its multi-targeted therapeutic effects, including gastric mucosal protection, modulation of inflammatory responses, and improvement of microcirculation. The discussion is well-supported by clinical studies and meta-analyses, underscoring the potential benefits of specific herbal compounds such as berberine, morroniside, and notoginsenoside R1. However, the review also acknowledges a key challenge—the lack of standardized research methodologies and evaluation criteria, which limits the broader clinical application of TCM. While the evidence presented suggests promising therapeutic effects, future research should focus on large-scale randomized controlled trials to further validate these findings and establish consistent guidelines for integrating TCM into mainstream gastroenterology practice. Additionally, a more detailed discussion on potential interactions between TCM and conventional Western therapies would strengthen the clinical relevance of this review. Overall, this article makes a valuable contribution to the understanding of CAG management and provides a strong foundation for future research in this field."

"The study by Real Martinez et al. provides valuable insights into the role of circulating myokines such as irisin and FGF21 in MASLD, particularly their association with severe steatosis and advanced liver fibrosis. However, the absence of a relationship between skeletal muscle alterations (SMAs) and liver fibrosis stages raises intriguing questions. Could the lack of association be attributed to the heterogeneity of the cohort, or might it suggest that SMAs play a more indirect role in MASLD progression? Additionally, how might other metabolic or inflammatory pathways, not directly evaluated in this study, influence the interplay between muscle health and liver disease? Further studies exploring these aspects, especially in longitudinal designs or larger cohorts, would be invaluable in clarifying these relationships and their implications for clinical practice."

"I congratulate the authors for the publication of their write up. It is well written with practical points. The information on greater likelihood of antibody generation with premixed insulins was new to me, although I believe it would have been partly due to the highly prevalent use of this form of insulin. I would like the authors to understand this point as well while promoting the advantages of the newer insulins. In the international guidelines, at diagnosis of diabetes if the blood glucose levels are above 300 mg/dl and/or glycosylated hemoglobin level is more than 10 %, it is suggested to start the patient on insulin to reduce the glucotoxicity. Once the blood glucose levels reduce, say after 2-3 weeks, the patient may be switched to oral anti-diabetic agents. Such a guideline recommended practice is regularly followed in developing countries such as ours. In such a situation I have observed that the acceptance rate of premixed insulin which involves two pricks, is a lot better than that of multiple short acting insulin doses along with basal insulin. Since the duration of premixed insulin therapy in this context is short, the possible side effects of anti-insulin antibody generation as well as lipodystrophy are less likely. "

"This study presents an evaluation of a novel contrast-enhanced catheter with a chamfered tip. Achieving selective biliary cannulation is one of the most challenging endoscopic maneuver. We congratulate the authors on demonstrating in this paper that a novel device granted higher rates of biliary cannulation when retrospectively compared to a standard sphincterotome. However, a few points warrant further discussion: 1. Generalizability: As a single-center retrospective study, the external validity of these findings could be enhanced with multicenter randomized trials. Variations in patient populations, procedural techniques, and institutional expertise might influence outcomes. 2. Non-expert outcomes: The results indicate a lack of significant improvement in outcomes among non-experts or trainees using the novel catheter. This suggests the device's utility may be contingent on the operator's skill. We also noticed that the expert performed procedure percentage was slightly higher (57% vs 50%) in the novel cathether group, and, although not statistically significant, this could explain the lower use of advanced or rescue cannulation techniques. 3. Adverse Events (AEs): While the overall AE rates were low and comparable between groups, the trend toward fewer cases of PEP with the novel catheter merits closer scrutiny in larger cohorts as this could be an advantage in patients at risk for PEP. On the other hand, the non-statistically significant difference between the two groups in PEP incidence suggests us that the device used to achieve initial selective cannulation maybe isn’t that relevant in increasing PEP risk or incidence, but this should be confirmed in larger studies. 4. Cost-effectiveness: Although not discussed, evaluating the cost implications of adopting this catheter, including potential savings from reduced reliance on rescue techniques and decreased procedural times, would be beneficial for broader clinical adoption. We should also think of the negative aspects: for example, like stone clearance, achieving cannulation with a catheter would require a subsequent switch to a sphincterotome, increasing procedure length and costs, as you would be using two devices instead of one to achieve cannulation. 5. Papilla characteristics: we noticed that in the baseline characteristics intradiverticular papillas and oral oriented papillas were less represented in the catheter group. These types of papilla could benefit of the angling capabilities of a sphincterotome, so this could be a bias that needs to be furthermore cleared. In our experience the angling capabilities of a sphincterotome are crucial in achieving bile duct cannulation in difficult situations. 6. Malignant disease: we do know that malignant diseases (e.g. pancreatic cancer) affecting the ampullar area negatively affect rates of cannulation and increase the need for rescue or advanced techniques of cannulation. This point could have been furthermore discussed by making a distinction between cannulation failures in the setting of benign vs. malignant disease in both groups. In conclusion, this study gives us valuable insights into advancing ERCP outcomes through innovative device design. We must experiment with more designs to compare results and finally choose the best device for cannulation in unexpected and difficult anatomies."

"As a colorectal surgeon interested in colorectal cancer and the microbiome, I found this study highly relevant. The authors effectively highlight differences in mucosa-associated colonic microbiota between colorectal cancer (CRC) and non-CRC patients in Indonesia. A key strength is the focus on mucosal rather than fecal microbiota, providing a clearer picture of the tumor microenvironment. The use of 16S rRNA sequencing with Oxford Nanopore Technologies enables detailed bacterial diversity analysis at the genus and species levels. The study confirms the increased presence of Fusobacterium nucleatum and Bacteroides fragilis in CRC patients, supporting the link between microbial dysbiosis and carcinogenesis. The diagnostic potential of these bacterial markers is particularly noteworthy. Further research with larger sample sizes and functional analyses, such as metagenomics or metabolomics, would enhance understanding of microbiota’s role in CRC. Additionally, while this study offers important insights for Asia, global research is needed to assess regional differences and their impact on CRC diagnostics and treatment."

"This case report highlights the importance of en-bloc resection without fragmentation during endoscopic procedures and the challenges of endoscopic treatment for anal canal cancer. Traditionally, anal lesions have been primarily managed by surgeons, but ESD-related technique is performed mainly by the gastrointestinal endoscopists of internal medicine. Future collaboration between internal medicine and surgery departments will be crucial. Surgery for anal cancer can significantly decrease patients' quality of life, which is why the authors' dedication to endoscopic treatment and follow-up is commendable. Anal canal cancer is rare, and it will be essential to determine which cases are suitable for endoscopic therapy in the future. With the increasing prevalence of inflammatory bowel diseases in Asian regions, a rise in anal cancer cases associated with conditions like Crohn's disease is anticipated. Further case reports in this field are desirable. "

"This paper examines the differences in proficiency of AI tools for IBD patients and is considered a critical study for the inevitable future utilization of large language models in healthcare. However, it is merely a comparative study of large language models, and it remains unclear whether it contributes to improving IBD patients' literacy. Regarding patient education, Crohn's disease and ulcerative colitis belong to different categories, making it challenging to evaluate IBD as a whole comprehensively. Separate evaluations for ulcerative colitis and Crohn's disease patients would be preferable. Furthermore, large language models alone are insufficient for shared decision-making that considers patients' social backgrounds for treatment selection, including biological agents (especially for Crohn's disease). Simply improving knowledge on several items through large language models may not be enough for clinical application. Future evaluations using large language models should address these points. "

However, I found some inaccuracies in the background. The style, language and grammar are appropriate. Since there are no figures or tables in the paper I answered no to the dedicated questions. Although the safety of POEM is well explained, superficial informations were provided on the precision and the post-procedural management. Therefore, I would focus the article mainly on the safety, explaining better the post-procedural management."

"Fu et al.'s recent study published in the World Journal of Psychiatry examines a complex connection between parenting stress, various family parenting styles, and the behavioral and emotional challenges that children experience. This study highlights the need for appropriate emotional management during the preschool years, demonstrating how differences in parental stress may have a significant impact on children's early emotional health. The analytical strength of this study is really impressive. The authors use structural equation modeling (SEM) to give a detailed examination of how different parenting styles mediate the relationships between these factors. Moreover, comprehensive questionnaire data collection contributes to a better understanding of family dynamics in a variety of environments. According to the findings, parents report high levels of stress, which suggests that they face constant challenges. The study discovers a link between "hostile/coercive" parenting and problem behaviors in children, revealing the deleterious effects of negative strategies for parenting. This conclusion is consistent with previous research, which emphasizes the importance of understanding how inadequate parenting may lead to behavioral problems in children. Conversely, the negative connection with "supportive/engaged" parenting implies that positive approaches might provide large protective benefits, emphasizing the importance of specific treatments. Besides, this study emphasizes how parenting styles serve as mediators in the relationship between parental stress and children's emotional health. The data show a 28.99% mediation impact, indicating that how parents handle stress influences the behaviors of their kids through their strategies for parenting. This finding not only strengthens the foundation for designing personalized therapies, but it also emphasizes the important need to improve parental practices. Also, the study points out the importance of providing parents with evidence-based strategies for managing their emotional health, with a focus on both parental and child well-being. The study aims to establish a caring environment for preschoolers by giving practical ways to reduce stress and promoting positive parenting behaviors. It focuses on the broader impacts of various parenting styles, implying that investing in parental support systems is important for enhancing children's mental health and promoting total family happiness. This perspective is consistent with current trends in mental health initiatives and requires a comprehensive effort to address families' emotional needs, supplying the framework for future research in this important area. Although Fu et al.'s work contributes significantly to our understanding of the link between parental stress and children's behavior, future research might profit from using a longitudinal strategy. Such an approach might allow researchers to investigate the changing dynamics of parental stress and child behavior over time, leading to a more comprehensive explanation of their causal relationships. Longitudinal studies may track how changes in parental stress affect the growth path of children's behavior by following the same set of participants at different points in time. This method not only gives a more in-depth understanding of these dynamics, but it also identifies potential mediators and moderators, offering light on the underlying reasons of the connections. Finally, this strategy may help us understand how the family environment affects children's developmental achievement. "

"This editorial pointed out the connection between adipose tissue and intestinal bacteria in Crohn's disease (CD). It is an interesting paper. The authors found that Clostridium innocuum migrates to adjacent adipose tissue and remains "trapped" in the fat. As a result, immune cell migration and macrophage differentiation increase, leading to fibrosis, narrowing, and, eventually, the formation of creeping fat. Although the main cytokine release is mainly TNFα and IL-6 in adipocytes, the cytokine profile changes over time, especially in fibrosis, may be related to IL-17, and the dominant cytokines will change from IL-12 to IL-23, as previously pointed out. It is interesting to evaluate the aging adipose tissue in CD. However, it is difficult to determine the actual time of onset in patients with CD, and it is challenging to evaluate this issue. "

However, as the results indicate that the therapeutic effects of N-hUCMSCs, serum-cultured hUCMSCs (S-hUCMSCs), and hyaluronic acid (HA) are comparable, the rationale for prioritizing N-hUCMSCs warrants further exploration, particularly in comparison to the well-established use of HA.

"he significant impact of surgical approaches on male sexual dysfunction after rectal cancer surgery is highlighted by both this letter to the editor and the latest study by Numata et al. published in Annals of Surgery1). Damage to the autonomic nervous system during rectal cancer surgery is a major cause of sexual dysfunction, with problems such as ejaculatory dysfunction, erectile dysfunction, and sexual dysfunction commonly reported. These complications are particularly common with open surgery, and previous research has also shown that the incidence of sexual dysfunction following surgery is high. However, advances in surgical techniques such as robotic surgery are expected to reduce these complications. The LANDMARC Study provided convincing evidence that robotic surgery significantly reduces the incidence of postoperative sexual dysfunction compared to laparoscopic surgery. The incidence of ejaculatory dysfunction at 12 months postoperatively was 25% in robotic surgery patients compared to 40.9% in laparoscopic surgery patients. The incidence of sexual dysfunction was 17.8% and 29%, respectively. This letter to editor alos emphasized the importance of accurate surgical technique and knowledge of pelvic nerve anatomy. It also discussed the benefits of new techniques such as robotic surgery and transanal total mesorectal excision (Ta-TME), as well as the use of intraoperative pelvic nerve monitoring. These advances enhance nerve preservation, reduce complications, and improve patients' postoperative quality of life. These findings highlight the need to adapt innovative surgical techniques in rectal cancer treatment to minimize adverse effects on sexual health while maintaining oncologic effectiveness. 1) Numata, Masakatsu, et al.

"The author suggests to use in all diabetic patients an interesting technique, the” body surface gastric mapping” (BSGM), to detect the onset of gastric dysmotility precursor of gastroparesis, instead of invasive procedures, as gastroscopy, manometry, emptying of radiopaque markers or radioactive bolus and breath tests . The idea is interesting , but there are some observations to make. First of all the author forgot a simple, not invasive, physiologic and reliable method to measure gastric emptying, that is real-time ultrasonography, which allows the use of a normal solid–liquid meal and gives an immediate result (1). Furthermore the author did not take into account the fact that, as indicated in figure 1 of ref. 4, the cause of delayed gastric emptying in gastroparesis may be also due, not only to antral dysmotility detectable with BSGM, but also to impaired pyloric relaxation upon arrival of antral peristalsis (pylorospasm) and, sometimes, to dysmotility of duodenum, which does not accept the bolus coming from the stomach. The pylorospasm, which was observed in 14 of 24 diabetics, by Mearin et al (2) forms part of the widespread disruption of gut motility that affects some patients with diabetes. Unfortunately these pyloric and duodenal motor abnormalities are not detected by the technique of BSGM, which could find a normal antral motility, giving the impression that everything is OK, while the gastric emptying is already delayed. Therefore I would suggest to monitor the diabetic patients with the real-time ultrasonography, which is able to detect also a minimal delay in gastric emptying harbinger of gastroparesis, and, if the gastric emptying is delayed, then perform the BSGM, to see if the cause of the slowing is due to antral dysmotility. If the latter examination is negative, then the cause of delayed gastric emptying shoul be pylorospasm or duodenal dysmotility.

"Exercise during pregnancy improve organ development in offspring with gestational diabetes mellitus Shengju Chen, Hangming Fan, Yu Chen Abstract In this commentary, we discuss the study by Tang et al., “Effect of exercise during pregnancy on offspring development through ameliorating high glucose and hypoxia in gestational diabetes mellitus”. Gestational diabetes mellitus (GDM), defined as ‘glucose intolerance with onset or first recognition during pregnancy’, impacts millions of women worldwide and poses significant health risks. Exercise during pregnancy has been shown to improve offspring health outcomes in obese mothers, potentially reducing epigenetic changes associated with maternal high-fat diets and minimizing abnormalities in lipid and glucose metabolism. However, while prenatal exercise’s impact on metabolic disorders in GDM offspring has been explored, its effects on organ growth remain insufficiently understood. Tang et al. identified GLUT1 and HIF1 as key regulators influencing the development of the heart, liver, and kidney in GDM offspring. Their study demonstrates that exercise during pregnancy supports organ development by inhibiting placental GLUT1 and HIF1 expression in GDM. This work contributes to understanding the role of GLUT1 and HIF1 in moderating the effects of prenatal exercise on organ development in GDM-affected offspring, supporting the idea that maternal exercise is an important intervention for improving offspring outcomes in GDM pregnancies and warrants further investigation in future epigenetic research. Introduction Gestational diabetes mellitus (GDM) is one of the most common pregnancy complications, affecting approximately 20.9 million pregnant women and their newborns worldwide as of 2020. GDM is associated with a range of adverse pregnancy outcomes, including preeclampsia, polyhydramnios, and fetal organomegaly (Pettitt et al., 1980). Additionally, GDM poses several short-term risks to offspring, such as neonatal respiratory distress, metabolic complications (Ferrara et al., 2007), and increased perinatal mortality rates. The GDM quintet management model recommends five core interventions to mitigate these risks, exercise, dietary regulation, maternal education, pharmacological treatment, and fetal health evaluation (Association, 2003). Pathophysiologically, GDM is characterized by hyperglycemia, glucose intolerance, and insulin resistance, typically manifesting in the late second to early third trimester of pregnancy (Buchanan et al., 2012, Jovanovic and Pettitt, 2001, Pereira et al., 2015). Several mechanisms have been proposed to explain these outcomes, including chronic fetal hyperinsulinemia, impaired oxygenation due to elevated metabolic rates, and metabolic acidosis (Freinkel, 1980). In this commentary, we discuss the article by Tang et al., recently published in the recent issue of the World Journal of Diabetes, which explores the impact of maternal exercise during pregnancy on organ development in offspring of mothers with GDM. Risks and complications associated with GDM In a healthy pregnancy, insulin sensitivity decreases to allow more glucose availability for the fetus; however, normoglycemia is typically maintained through increased insulin production by pancreatic β-cells. In cases of GDM, the pancreas may fail to produce sufficient insulin, resulting in elevated blood glucose levels and the onset of GDM (Freinkel, 1980). GDM pregnancies can lead to additional complications that negatively impact maternal and fetal health (Poston et al., 2011). Immediate complications in offspring of overweight women with GDM include macrosomia, the most severe of which is shoulder dystocia; other neonatal complications such as hypoglycemia and hyperbilirubinemia have also been reported (Kaaja and Rönnemaa, 2008, Lecomte et al., 2017). Long-term exposure to GDM increases the risk of obesity, type 2 diabetes, and cardiovascular diseases (CVD) as offspring age (Capobianco et al., 2016). Epigenetic studies indicate that the intrauterine environment significantly influences offspring organ development, and exposure to elevated maternal blood levels can impair fetal health. Maintaining a healthy uterine environment is thus essential to promoting favorable health outcomes in offspring. Exercise, as a non-pharmacological intervention without side effects, is widely used in diabetes prevention and management. Given that pregnancy is a period when non-pharmacological interventions are especially favored by medical staff and patients, exercise is particularly promising for managing GDM. Benefits of exercise during pregnancy Eight national guidelines on exercise during pregnancy recommend 60-150 minutes of aerobic exercise per week for healthy pregnant women (Savvaki et al., 2018). The benefits of exercise for pregnant women include improved overall health, better weight management, reduced risk of GDM and gestational hypertension (Davenport et al., 2018, Yu et al., 2018). For women with GDM, moderate aerobic or combined exercise has been shown to enhance postprandial blood glucose control (Walter and Klaus, 2014), although the optimal duration and intensity remain unclear. Moderate exercise during pregnancy can improve maternal insulin sensitivity, reduce placental lipid accumulation in both male and female fetuses, and alleviate hypoxia, positively influencing the intrauterine environment and fetal growth (Laker et al., 2014). Exercise during pregnancy also promotes healthier liver glucose production, helps maintain liver triglycerides levels, and prevents the expression of liver enzymes and genes in offspring caused by maternal high-fat diet, thereby improving the offspring’s metabolic profile. These findings suggest that maternal exercise can mitigate modifications linked to a high-fat diet, protecting offspring from future metabolic diseases. Regulation of GLUT1 by maternal exercise and offspring health outcomes in GDM The placenta is responsible for transporting essential nutrients and oxygen from maternal to fetal circulation, as fetal gluconeogenesis is minimal (Kalhan and Parimi, 2000). GDM disrupts placental function, leading to various morphological (Treesh and Khair, 2015) and vascular changes (Aldahmash et al., 2022, El Sawy et al., 2018) and including fetal vascular changes and DNA methylation (Song et al., 2022). Placental transport proteins, such as glucose transporters, facilitate nutrient transfer from the mother to the fetus. Glucose is the primary energy source for both placental and fetal growth (Stanirowski et al., 2017), with GLUT1 and GLUT3 serving as the main placental glucose transport proteins in humans. GLUT1 is expressed in syncytiotrophoblast microvilli and the basal membrane, as well as in vascular endothelium and cell layers (Brown et al., 2011, Jansson et al., 1993). Research on GDM in humans and mice shows increased placental GLUT1 expression, likely due to increased glucose availability in maternal circulation, which enhances placental glucose consumption (Muralimanoharan et al., 2016). This increase in GLUT1 may contribute to the higher rates of macrosomia observed in GDM pregnancies (Stanirowski et al., 2022). Moreover, GDM leads to placental hypoxia, elevated hypoxia-inducible (HIF) levels, and glial cell missing 1 degradation, inhibiting trophoblast migration and invasion. Exercise during pregnancy can significantly reduce placental GLUT1 expression and alleviate hypoxia. Silencing GLUT1 can partially counteract the reduced trophoblast migration caused by hyperglycemia and hypoxia. Beyond energy metabolism, GLUT1 is also related to the development of the heart, liver, and kidneys. Zhang et al. investigated the relationship between GLUT1 expression in these organs and their structural and pathological changes, examining how exercise influences growth and development in offspring with GDM. In a neonatal GLUT1 transgenic heart model, increased glucose metabolism can stimulate hyperplastic growth after cardiac injury (Fajardo et al., 2021). Maternal exercise during pregnancy has been shown to lower hepatic GLUT1 expression, reduce inflammatory infiltration, and decrease the risk of liver disease in adult offspring (Baker and Friedman, 2018). In the kidney, GLUT1 functions vary by cell type; elevated GLUT1 in mesangial cells can impair kidney structure, while in podocytes, it may reduce mesangial expansion and fibronectin accumulation (Chen et al., 2024). Future research is recommended to clarify the specific mechanisms by which exercise benefits renal structure and function in GDM offspring. Directions for future studies The specific mechanisms by which maternal exercise during pregnancy improves health outcomes in diabetic offspring remain under investigation, with multiple synergistic pathways likely involved. Given its role in glucose metabolism, GLUT1 is of particular interest as a regulatory factor in mitigating adverse outcomes in offspring of mothers with GDM through exercise. This underscores the significant influence of exercise on glucose metabolism, which enhances the intrauterine environment and supports offspring health. Improved placental GLUT1 expression appears to regulate the GLUT1 levels in offspring organs, positively impacting organ development. These findings extend our understanding of exercise-related epigenetics modifications, yet further research is essential to clarify the pathways through which maternal exercise regulates placental GLUT1, thereby promoting healthy organ development in offspring and underscoring the benefits of prenatal exercise. Conclusion GDM can lead to adverse outcomes for both the mother and their offspring. Maternal exercise during pregnancy improves the intrauterine environment and enhances offspring health. Elevated maternal blood glucose can cause fetal hyperinsulinemia, hypoxia, and metabolic acidosis. Exercise enhances glucose metabolism, reduces high blood sugar levels, and supports a healthier intrauterine environment, thereby decreasing the risk of metabolic diseases in offspring. The study by Tang et al. confirms the association between elevated placental GLUT1 expression in GDM and abnormal offspring organ development related to hypoxia. Their research demonstrates that exercise during pregnancy can improve placental glucose transport and reduce hypoxia, mitigating adverse developmental outcomes in offspring organs at various stages. These findings validate, across human, animal, and cellular models, the molecular mechanisms through which maternal exercise enhances organ development in offspring affected by GDM. This contributes to clinical application and emphasizes the role of epigenetics in promoting offspring health. As research in epigenetic progresses, the pathways through exercise benefits GDM-affected offspring will become clearer, with GLUT1 as a central regulator of glucose metabolism. Further investigation into these mechanisms will advance our understanding of how maternal exercise supports healthier outcomes for GDM offspring. Aldahmash, W.M., Alwasel, S.H., Aljerian, K., 2022.

Corresponding author: Meng-Na Zhang, Molecular Diagnosis Center,The Affiliated Hospital of Chengde Medical University, Chengde, China zhangmengna2014@sina.com Abstract Serotonin 1A receptor polymorphism (5-HTR1A) C-1019G polymorphism (rs6295) is a functional regulatory variants reported to be related with multiple phenotypes including major depression, suicidal behavior and antidepressant response. However, clinical studies investigating this variant and its potential phenotypes had incongruous findings. Molecular studies on this variant showed it does regulate HTR1A expression but meta-analysis showed it had negative relationship with antidepressant drug response in major depressive disorder (MDD), as reported by Wu et al. in the lasted issue of the World Journal of Psychiatry. This suggested the importance of re-evaluating the clinical impact of functional regulatory variants. Key words: regulatory variants, snp-meta, snp-phenotype association Core Tip: Functional regulatory variants might have negative relationship with putative phenotypes even it do regulate gene expression. Single nucleotide polymorphism (SNP) meta analysis helps to identify a more robust SNP-phenotype relationship. We carefully read the article titled “Association between 5-HTR1A gene C-1019G polymorphism and antidepressant response in patients with major depressive disorder: A meta-analysis” published in the World Journal of Psychiatry by Wu et al.[1]. In this study the authors reviewed 11 clinical studies about serotonin 1A receptor polymorphism (5-HTR1A) C-1019G polymorphism (rs6295) and antidepressant response. Though reported to be related with major depression[2], suicidal behavior[3] and antidepressant response[4], rs6295 did not show significant association with antidepressant drug response in major depressive disorder (MDD) in this meta-analysis. Genome-wide association studies (GWAS) show to be a useful tool to investigate the effect of polymorphism on clinical phenotypes. Most disease-associated variants are non-coding variants. Researchers have developed multiple methods to identify functional regulatory variants from putative regulatory regions and their cis-regulated genes, like massively parallel reporter assays (MPRAs) and expression quantitative trait loci (eQTL)[5,6]. The 5-HTR1A C-1019G polymorphism (rs6295) reviewed by Wu et al. [1] is a functional upstream variant that affects HTR1A expression but not associates with antidepressant response in patients with MDD, though the 5-HT1A receptor is a primary target for most antidepressant drugs. This variant has been reported to influence HTR1A expression in numerous molecular studies. The C-allele of this variant is capable of interacting with transcription factors (TFs) such as Hes1, Hes5, and Deaf1, whereas the G-allele fails to bind these TFs [7]. Although these three TFs are typically regarded as repressors, the activity of Deaf1 at the 5-HT1A promoter exhibits opposing effects in presynaptic versus postsynaptic neuronal cells [7]. In the human prefrontal cortex, the G-allele demonstrates a lower expression level compared to the C-allele; however, this pattern does not hold true for the midbrain and hippocampus [8]. In a humanized mouse model, subjects with GG genotype exhibited higher levels of HTR1A mRNA and protein than those with CC genotype in a line-dependent manner [9]. Furthermore, in 5-HT1A-expressing neuronal cells, the G-allele was found to downregulate 5-HT1A expression [10]. These showed the complexity of regulatory variant function. Clinical researches on rs6295 had incongruous findings, raising the need for a SNP-based meta analysis. A single variant approach is a classical method to ascertain the relationship between a variant and putative phenotypes. Selective serotonin re-uptake Inhibitors (SSRIs) like fluoxetine, paroxetine, sertraline, citalopram, and fluvoxamine were included in this meta analysis, however, the result showed no significant correlation between this variation and antidepressant drug efficacy in MDD in the dominant model (CG vs CC), recessive model (GG vs CC), and combined dominant model (CG+GG vs CC). The 11 clinical studies collected in their meta analysis included multiple populations from over 10 countries with low to moderate heterogeneity and were scored 7-9 according to the Newcastle-Ottawa Scale (NOS), suggesting a result with higher confidence. The negative correlation might due to gene-gene interactions or gene-environment interactions in MDD and its treatment. A genome-wide linkage analysis for MDD showed that association of LHPP SNPs to MDD were depended on HTR1A -1019G allele [11]. Single variant approaches are limited by lower statistical detection power because most phenotypes result from the influence of many genetic variants in many genes and pathways[12]. This limitation is particularly pronounced in pharmacogenetics and multigenic diseases like MDD. Large-scale meta-analysis of GWAS might overcome this disadvantage. However, phenotype analysis involving rs6295 through GWAS is inherently limited due to its ambiguous nature (C/G). It is challenging to distinguish which complementary allele serves as the effect allele. Furthermore, the minor allele frequency (MAF) of rs6295 is G=0.483 in gnomAD and C=0.458 in 1000G, making it impossible to solve the problem by allele frequency. Ambiguous SNPs with allele frequencies close to 0.5 are usually removed in GWAS [13]. Therefore, a SNP meta-analysis remains a viable option for investigating rs6295. The clinical impacts of regulatory variants in monogenic Mendelian diseases have also been noticed. Many bioinformatic tools were developed to predict TF binding of regulatory variants like SNEEP [14]. Many of them use eQTL datasets as training and validation sets. In rs6295’s case, the variant had different functions in different brain regions, and showed negative significance to putative related phenotype. This suggested a limitation of using these tools to predict clinical candidate variants. However, there are few clinical curated regulatory variants databases available. There are only hundreds of regulatory variants in Clinvar database classified as pathogenic/likely pathogenic/benign/likely benign (data not shown). That’s not enough to feed a complex model. Overall, the negative relationship between the functional regulatory variant rs6295 and antidepressant response underscores the importance of re-evaluating the clinical significance of functional regulatory variants. Both positive and negative meta-analyses are essential for establishing robust relationships between polymorphisms and phenotypes. References [1] Wu HN, Zhu SY, Zhang LN, Shen BH, Xu LL.

"This study provides valuable insights into the treatment of Helicobacter pylori infection. The comparison between low - dose and standard - dose tetracycline in combination with amoxicillin quadruple therapy is well - designed and the results are significant.The research is comprehensive, considering factors such as eradication rates and adverse events. It offers a potential alternative treatment option with better safety profiles, which is beneficial for patients. Also, there still exist some questions to be considered. 1. Regarding the article structure • When introducing the research background, various antibiotic resistance rates against Helicobacter pylori are listed in detail. However, could this part be presented more concisely and focused more on the resistance situations of tetracycline and amoxicillin directly related to this study? • In the research methods section, could the description of the patient inclusion and exclusion criteria be more focused on the key points and avoid being interfered by too many irrelevant details? For example, the emphasis could be placed on those factors that may have a crucial impact on the research results. • In the results presentation part, could the comparison results of different groups be shown in a clearer structure? For example, the main results of all groups could be presented first, and then the situations of each subgroup (such as the primary treatment group and the rescue treatment group) could be elaborated in detail respectively, which would make it easier for readers to grasp the overall logic. 2. Regarding the article content • When discussing the advantages of low - dose tetracycline, besides comparing the eradication rates and adverse events with the standard - dose tetracycline, could the possible mechanism of action be further explored? This would help readers understand the research results more in - depth. • Some factors affecting the Helicobacter pylori eradication rate are mentioned in the article, such as patient compliance, smoking history, etc. However, could a more in - depth analysis of the interactions between these factors be carried out? For example, does smoking affect the eradication rate by influencing compliance? • Regarding the content of the gut microbiota, although it is mentioned in the limitations that the impact of the low - dose tetracycline regimen on the gut microbiota has not been studied, could the future research directions be more specifically elaborated on how to design relevant studies to explore this issue? 3. Regarding the charts • There is a lot of data in the tables in the article, and some abbreviations in the tables may confuse readers. Could more detailed explanations be given below the tables or where the abbreviations first appear? • Could the titles of the charts more clearly reflect the core content of the charts? For example, some chart titles only simply describe the variables involved in the charts without highlighting the main conclusions or trends. • Could some more charts be considered to present the key information in the research more intuitively? For example, charts could be used to show the occurrence trends of adverse events in different tetracycline dose groups during the treatment process, or to present the relative magnitudes of the impacts of different factors on the eradication rate. 4.Further study • It would be interesting to see if the results hold true in different populations and geographical regions. • The study could have included a more detailed analysis of the long - term effectiveness and potential recurrence of H. pylori infection after treatment.

Reasonable experimental design: The study established a mice model of colon cancer and divided it into several experimental groups (including a control group and groups with different doses of ISAP), a design that effectively compares the effects of different doses of ISAP on tumor suppression. 3. Detailed data analysis: The paper provides detailed data on the measurement of mice weight, tumor inhibition rate, and related protein expression levels, with clear and understandable results. These data provide empirical support for the anti-tumor mechanism of ISAP. 4. In-depth mechanism exploration: By analyzing key proteins in the ERK/MAPK signaling pathway, the paper explores the potential mechanism of action of ISAP, providing new ideas for subsequent research. 5. Clinical significance: Although the study has achieved positive results in the mice model, the effectiveness and safety of ISAP still need to be verified in clinical trials. This point can be further emphasized in the discussion section. 6. Language and structure: The language of the paper is relatively fluent, with a clear structure, making it easy for readers to understand. However, the explanation of some professional terms could be more detailed, for the understanding of non-professional readers. Overall, this paper provides strong support for the potential of ISAP in the treatment of colon cancer, looking forward to seeing more clinical research results in the future."

"The original article by Wang FD et al., "Gamma-aminobutyric acid enhances miR-21-5p loading into adipose-derived stem cell extracellular vesicles to alleviate myocardial ischaemia-reperfusion injury via TXNIP regulation," is very good. GABA-induced miR-21-5p-loaded EVs utilise a unique mechanism to lessen myocardial ischaemia-reperfusion injury (MIRI) and present a novel method for managing MIRI through oxidative stress modulation. The study reported that miR-21-5p exerts its effects through a direct interaction with TXNIP in cardiomyocytes, thereby triggering oxidative stress and elucidating related molecular mechanisms. Furthermore, this work systematically employs in vivo, in vitro, and a variety of imaging methods with gene knockout models to provide comprehensive methodological proofs. Considering myocardial ischaemia is a common clinical condition, this study has high translational relevance. But there are few queries: The experiment only evaluates its EV source in inguinal ADSCs and could miss other potential beneficial configurations of EV. It is still unclear whether these short-term therapeutic effects are sustainable or if they interfere with repeated dosing against MIRI, despite the study's lack of a long-term assessment. The process of producing, standardizing, and ensuring the safety of EVs for human use could potentially complicate the clinical translation of the latter strategy."

" Commentary: Predictors of survival in autoimmune liver disease overlap syndromes Jian-Guo Zhang,Biao Wen Jian-Guo Zhang,Biao Wen,Department of Gastroenterology, The First Affiliated Hospital of Chengdu Medical College, Chengdu 610000, Sichuan Province, China Author contributions:Jian-Guo Zhang wrote the original draft; Biao Wen contributed to conceptualization, writing, reviewing and editing; Jian-Guo Zhang and Biao Wen participated in drafting the manuscript; and all authors have read and approved the final version of the manuscript. ORCID number:0000-0001-5226-5981 Corresponding author:Biao Wen,MD, PhD,Assistant Professor,Department of Gastroenterology, The First Affiliated Hospital of Chengdu Medical College,No. 312, Middle Section of Baoguang Avenue, Xindu District, Chengdu 610000, Sichuan Province, China. 820695761@qq.com We perused the article authored by Jayabalan et al[1]with considerable interest and extend our congratulations to the authors for their commendable endeavor. The authors have reported a prospective investigation into the predictors of survival in patients with autoimmune liver disease overlap syndromes (AILDOS)[1]. The study's conclusion suggests that the LOS holds potential as a predictive tool for liver-related mortality in individuals with autoimmune hepatitis and primary biliary cholangitis overlap (AIH-PBC)[1]. However, several aspects of this study merit further scrutiny and discussion. Firstly, a critical exclusion criterion for the study was the prior performance of a liver transplant prior to enrollment[1]. Upon consideration, we postulated the possibility that a portion of the enrolled patients might harbor coexisting liver pathology stemming from disparate causes (including, but not limited to, alcoholic liver disease or viral hepatitis), which could introduce bias and complicate the interpretation of our results. Therefore, we advised the authors to implement rigorous exclusion criteria for such patients to uphold the accuracy and reliability of our findings. Secondly, the diagnoses of autoimmune hepatitis (AIH), primary biliary cirrhosis (PBC), and primary sclerosing cholangitis (PSC) were established in accordance with the criteria stipulated by the International Autoimmune Hepatitis Group, the European Association for the Study of the Liver Clinical Practice Guidelines, and the American College of Gastroenterology Clinical Guidelines, respectively[1-4]. It is noteworthy that these diagnostic criteria originate from disparate geographical regions, and the progression of research concerning each disease varies across these regions. Consequently, such variability may potentially impact the precision of the study's findings. In light of this, we propose that the authors consider adopting diagnostic criteria from a uniform geographical region. Therefore, we recommend the uniform application of diagnostic guidelines or consensus recommendations established by reputable institutions in the United States for the purposes of disease ascertainment. Such standardization is poised to substantially elevate the reliability and validity of the research findings, thereby reinforcing the scientific rigor and credibility of the conducted studies.[4-6]. Thirdly, the authors confined their analysis solely to the occurrence or absence of liver-related mortality, while neglecting to account for the medical interventions undergone by the patients during the follow-up period[1]. It is imperative to elucidate the potential impact of these interventions on the study's findings. A comprehensive assessment of the medical interventions received by the patients is crucial for ensuring the accuracy and robustness of the study's conclusions. Ultimately, as highlighted by the authors, the primary limitation of this study is the relatively modest sample size[1]. Consequently, it is imperative that future research endeavors incorporate larger sample populations and adopt a multicenter design to validate the findings of the present study and further elucidate the pertinence to patients with AIH-PSC. Conflict-of-interest statement: No potential conflicts of interest relevant to this article were reported.
