Therapeutic Profile and Prognostic Factors of Patients Suffering from Upper Digestive Bleeding at Sikasso Regional Hospital

Introduction: Upper digestive hemorrhage is one of the main digestive emergencies and remains a major cause of morbidity and mortality in Mali. The aim of this study was to describe the therapeutic profile and outcome of patients suffering from upper digestive haemorrhage. Methodology: This was a prospective study carried out in the internal medicine department of the Sikasso Regional Hospital from August 2022 to July 2023. All adult patients presenting with upper digestive haemorrhage and having given their consent, were included. Data were analyzed using SPSS version 21 software. Results: Sixty-three patients were enrolled. The mean age was 49.7 ± 18.99 years, with a male-female sex ratio of 2.2. Ruptured esophageal varices (37.5%) and peptic ulcer (25%) were the main etiologies. Pharmacological treatment was dominated by proton pump inhibitors (85.7%). Hemostasis endoscopy accounted for 3.17%. The evolution was marked by hemorrhagic arrest (69.84%), recurrence of hemorrhage (11.11%) and death (19.04%), the main cause of which was hemorrhagic shock (58.3%). We found no statistically significant relationship between prognosis and etiologies (P = 0.11), and length of hospital stay (P = 0.18). Conclusion: Hemostasis endoscopy remains a challenge for Sikasso Hospital. A holistic strategy of communication and community awareness-raising, combined with adequate technical facilities, will help to improve patient care and outcomes.

Intricate roles of estrogen and estrogen receptors in digestive system cancers:a systematic review

Gender disparities are evident across different types of digestive system cancers,which are typically characterized by a lower incidence and mortality rate in females compared to males.This finding suggests a potential protective role of female steroid hormones,particularly estrogen,in the development of these cancers.Estrogen is a well-known sex hormone that not only regulates the reproductive system but also exerts diverse effects on non-reproductive organs mediated through interactions with estrogen receptors(ERs),including the classic(ERαand ERβ)and non-traditional ERs[G protein-coupled estrogen receptor(GPER)].Recent advances have contributed to our comprehension of the mechanisms underlying ERs in digestive system cancers.In this comprehensive review we summarize the current understanding of the intricate roles played by estrogen and ERs in the major types of digestive system cancers,including hepatocellular,pancreatic,esophageal,gastric,and colorectal carcinoma.Furthermore,we discuss the potential molecular mechanisms underlying ERα,ERβ,and GPER effects,and propose perspectives on innovative therapies and preventive measures targeting the pathways regulated by estrogen and ERs.The roles of estrogen and ERs in digestive system cancers are complicated and depend on the cell type and tissue involved.Additionally,deciphering the intricate roles of estrogen,ERs,and the associated signaling pathways may guide the discovery of novel and tailored therapeutic and preventive strategies for digestive system cancers,eventually improving the care and clinical outcomes for the substantial number of individuals worldwide affected by these malignancies.

A Comprehensive Study of the Association between LEPR Gene rs1137101 Variant and Risk of Digestive System Cancers

Objective The leptin receptor,encoded by the LEPR gene,is involved in tumorigenesis.A potential functional variant of LEPR,rs1137101(Gln223Arg),has been extensively investigated for its contribution to the risk of digestive system(DS)cancers,but results remain conflicting rather than conclusive.Here,we performed a case–control study and subsequent meta-analysis to examine the association between rs1137101 and DS cancer risk.Methods A total of 1,727 patients with cancer(gastric/liver/colorectal:460/480/787)and 800 healthy controls were recruited.Genotyping of rs1137101 was conducted using a polymerase chain reactionrestriction fragment length polymorphism(PCR-RFLP)assay and confirmed using Sanger sequencing.Twenty-four eligible studies were included in the meta-analysis.Results After Bonferroni correction,the case–control study revealed that rs1137101 was significantly associated with the risk of liver cancer in the Hubei Chinese population.The meta-analysis suggested that rs1137101 is significantly associated with the risk of overall DS,gastric,and liver cancer in the Chinese population.Conclusion The LEPR rs1137101 variant may be a genetic biomarker for susceptibility to DS cancers(especially liver and gastric cancer)in the Chinese population.

Harnessing autophagy: A potential breakthrough in digestive disease treatment

Autophagy,a conserved cellular degradation process,is crucial for various cellular processes such as immune responses,inflammation,metabolic and oxidative stress adaptation,cell proliferation,development,and tissue repair and remodeling.Dysregulation of autophagy is suspected in numerous diseases,including cancer,neurodegenerative diseases,digestive disorders,metabolic syndromes,and infectious and inflammatory diseases.If autophagy is disrupted,for example,this can have serious consequences and lead to chronic inflammation and tissue damage,as occurs in diseases such as Chron's disease and ulcerative colitis.On the other hand,the influence of autophagy on the development and progression of cancer is not clear.Autophagy can both suppress and promote the progression and metastasis of cancer at various stages.From inflammatory bowel diseases to gastrointestinal cancer,researchers are discovering the intricate role of autophagy in maintaining gut health and its potential as a therapeutic target.Researchers should carefully consider the nature and progression of diseases such as cancer when trying to determine whether inhibiting or stimulating autophagy is likely to be beneficial.Multidisciplinary approaches that combine cutting-edge research with clinical expertise are key to unlocking the full therapeutic potential of autophagy in digestive diseases.

Immunomodulatory and chemopreventive effects of resveratrol on the digestive system cancers

Resveratrol(RSV),the primary polyphenol found in grapes,has been revealed to have anti-inflammatory properties by reducing the capacity of the peripheral blood mononuclear cells to produce pro-inflammatory cytokines,including IL-1β,IL-6,IL-1ra and TNFα.Considering the close association between chronic inflammation and cancer development,RSV’s immunomodulatory properties are one way by which the polyphenol may inhibit cancer initiation,proliferation,neovascularization,and migration.Resveratrol influences the generation of microtumor environment which is one of the key factors in cancer progress.In addition to immunomodulation,RSV inhibits cancer development by expressing anti-oxidant effects,causing cell cycle arrest,stimulating the function of certain enzymes,and activating cell signaling pathways.The end outcome is one of the various forms of cell death,including apoptosis,pyroptosis,necroptosis,and more,as it has been observed in vitro.RSV has been shown to act against cancer in practically every organ,while its effects on colon cancer have been documented more frequently.It is remarkable that longer-term clinical studies that may have established the potential for this natural substance to serve as a therapeutic adjuvant to traditional anti-cancer medications were not prompted by the encouraging outcomes seen with cancer cells treated with non-toxic doses of resveratrol.The current review aims to assess the recent findings about the immunological and anti-cancer characteristics of RSV,with a particular emphasis on cancers of the digestive tract,as a challenge for future clinical research that may contribute to the better prognosis of cancer.

Insights into the history and tendency of glycosylation and digestive system tumor:A bibliometric-based visual analysis

BACKGROUND Glycosylation,a commonly occurring post-translational modification,is highly expressed in several tumors,specifically in those of the digestive system,and plays a role in various cellular pathophysiological mechanisms.Although the importance and detection methods of glycosylation in digestive system tumors have garnered increasing attention in recent years,bibliometric analysis of this field remains scarce.The present study aims to identify the developmental trends and research hotspots of glycosylation in digestive system tumors.AIM To find and identify the developmental trends and research hotspots of glycosylation in digestive system tumors.METHODS We obtained relevant literature from the Web of Science Core Collection and employed VOSviewer 1.6.19 and CiteSpace(version 6.1.R6)to perform bibliometric analysis.RESULTS A total of 2042 documents spanning from 1978 to the present were analyzed,with the research process divided into three phases:the period of obscurity(1978-1990),continuous development period(1991-2006),and the rapid outbreak period(2007-2023).These documents were authored by researchers from 66 countries or regions,with the United States and China leading in terms of publication output.Reis Celso A had the highest number of publications,while Pinho SS was the most cited author.Co-occurrence analysis revealed the most popular keywords in this field are glycosylation,expression,cancer,colorectal cancer,and pancreatic cancer.Furthermore,the Journal of Proteome Research was the most prolific journal in terms of publications,while the Journal of Biological Chemistry had the most citations.CONCLUSION The bibliometric analysis shows current research focus is primarily on basic research in this field.However,future research should aim to utilize glycosylation as a target for treating tumor patients.

Procyanidin A_1 and its digestive products alleviate acrylamide-induced IPEC-J2 cell damage through regulating Keap1/Nrf2 pathway

Our previous study has revealed that procyanidin A_(1)(A_(1))and its simulated digestive product(D-A,)can alleviate acrylamide(ACR)-induced intestine cell damage.However,the underlying mechanism remains unknown.In this study,we elucidated the molecular mechanism for and D-A_(1) to alleviate ACR-stimulated IPEC-J2 cell damage.ACR slightly activated nuclear factor erythroid 2-related factor 2(Nrf2)signaling and its target genes,but this activation could not reduce intestine cell damage.A_(1) and D-A_(1) could alleviate ACR-induced cell damage,but the effect was abrogated in cells transiently transfected with Nrf2 small interfering RNA(siRNA).Further investigation confirmed that A_(1) and D-A_(1) interacted with Ketch-like ECH-associated protein 1(Keapl),which boosted the stabilization of Nrf2,subsequently promoted the translocation of Nrf2 into the nucleus,and further increased the expression of antioxidant proteins,thereby inhibiting glutathione(GSH)consumption,maintaining redox balance and eventually alleviating ACR-induced cell damage.Importantly,there was no difference between A_(1) and D-A_(1) treated groups,indicating that A_(1) can tolerate gastrointestinal digestion and may be a potential compound to limit the toxicity of ACR.

Practical hints for the diagnosis of mixed neuroendocrine-nonneuroendocrine neoplasms of the digestive system

In this editorial,a comment on the article by Díaz-López et al published in the recent issue of the 2024 is provided.We focus on the practical implications critical for providing a correct and complete diagnosis of mixed neuroendocrine-nonneuroendocrine neoplasm(MiNEN)in the gastrointestinal system.The diagnosis of MiNEN begins with the recognition of neuroendocrine features in one component of a biphasic tumor.The non-neuroendocrine counterpart can be virtually represented by any neoplastic type,even though the most frequent histologies are glandular and squamous.However,qualification of the neuroendocrine component requires histological and immunohistochemical confirmation.Neuroendocrine tumors are characterized by a peculiar architectural organization and bland nuclei with granular“salt and pepper”chromatin.Although neuroendocrine carcinomas have multiple and variable presentations,they typically show a solid or organoid architecture.The histological aspect needs to be confirmed by immunohistochemistry,and a diagnosis is confirmed whenever the expression of keratin and neuroendocrine markers is observed.Once both histopathological and immunohistochemical features of neuroendocrine neoplasms are identified,it is important to consider the three major pitfalls of MiNEN diagnostics:(1)Entrapment of neuroendocrine non-neoplastic cells within the tumor mass;(2)Differential diagnosis with amphicrine neoplasms;and(3)Differential diagnosis of tumors that partially express neuroendocrine markers.According to the current guidelines for diagnosing digestive MiNEN,each component must represent at least 30%of the entire neoplastic mass.Although the high-grade histopathological subtype frequently determines disease prognosis,both components can significantly affect prognosis.Thus,if one of the components,either neuroendocrine or non-neuroendocrine,does not fulfill the volumetric criteria,the guidelines still encourage reporting it.These strict criteria are essential for correctly recognizing and characterizing digestive MiNENs.This task is essential because it has prognostic relevance and substantial potential value for guiding further studies in this field.In the future,systematic analyses should be performed to validate or reconsider the current 30%cutoff value.

Advances in the diagnosis and treatment of MET-variant digestive tract tumors

The receptor tyrosine kinase encoded by the MET gene plays an important role in various cellular processes such as growth,survival,migration and angiogenesis,and its abnormal activation is closely related to the occurrence and development of various tumors.This article reviews the recent advances in diagnosis and treatment of MET-variant digestive tract tumors.In terms of diagnosis,the application of next-generation sequencing technology and liquid biopsy technology makes the detection of MET variants more accurate and efficient,providing a reliable basis for individualized treatment.In terms of treatment,MET inhibitors such as crizotinib and cabotinib have shown good efficacy in clinical trials.In addition,the combination of immunotherapy and MET inhibitors also demonstrated potential synergies,further improving the therapeutic effect.However,the complexity and heterogeneity of drug resistance mechanisms are still one of the difficulties in current research.In the future,it is necessary to further deepen the understanding of the mechanism of MET variation and explore new combination treatment strategies to improve the overall survival rate and quality of life of patients.The diagnosis and treatment of MET-variant digestive tract tumors are moving towards precision and individualization,and have broad application prospects.

Analysis of sleep quality,disease uncertainty,and psychological tolerance in patients undergoing chemotherapy for digestive tract malignancies

BACKGROUND Colorectal cancer is the second leading cause of cancer-related deaths among digestive tract malignancies,following gastric cancer.Sleep is of great significance for maintaining human health.The incidence of sleep disorders in patients with cancer is approximately twice that observed in the general population.Lack of sleep can prolong hospital stays,increase the likelihood of infection,and increase mortality rates.Therefore,studying the factors related to sleep quality is significant for improving the quality of life of patients with malignant tumors of the digestive tract.AIM To investigate the relationships among sleep quality,disease uncertainty,and psychological resilience in patients undergoing chemotherapy for digestive tract malignancies.METHODS A total of 131 patients with malignant digestive tract tumors who were treated at Hefei BOE Hospital between April 2021 and September 2022 were selected as research participants.Based on their Pittsburgh Sleep Quality Index(PSQI)scores,participants were divided into either the sleep disorder group(PSQI score>7)or the normal sleep group(PSQI score≤7).The clinical data—together with the Mishel Uncertainty in Illness Scale for Adults(MUIS-A)and Connor-Davidson Resilience Scale(CD-RISC)scores—were compared.RESULTS In this study,78(59.54%)patients with digestive tract malignancies developed sleep disorders after chemotherapy.Sleep disorder incidence was higher in patients with colorectal cancer than in those with gastric and esophageal cancers(P<0.05).The total MUIS-A score and those for each item in the sleep disorder group were higher than those in the normal sleep group.The total CD-RISC score and those for each item in the sleep disorder group were lower than those in the normal sleep group(P<0.05).The PSQI scores of patients with malignant digestive tract tumors were positively correlated with the scores for lack of disease information,disease uncertainty,and unpredictability in the MUIS-A and negatively correlated with the scores for tenacity,self-improvement,and optimism in the CD-RISC(P<0.05).CONCLUSION Patients undergoing chemotherapy for digestive tract malignancies are prone to sleep problems related to disease uncertainty and psychological resilience.Therefore,interventions can be implemented to improve their sleep quality.

Blastomas of the digestive system in adults:A review

Blastomas,characterized by a mixture of mesenchymal,epithelial,and undifferentiated blastematous components,are rare malignant neoplasms originating from precursor blast cells.This review focuses on digestive system blastomas in adult patients,including gastroblastoma,hepatoblastoma,and pancreatoblastoma.Gastroblastoma is a biphasic,epitheliomesenchymal tumor,with only sixteen cases reported to date.In addition to the characteristic histology,metastasisassociated lung adenocarcinoma transcript 1-glioma-associated oncogene homolog 1 gene fusion is typical,although recently novel ewing sarcoma breakpoint region 1-c-terminal binding protein 1 and patched 1-glioma-associated oncogene homolog 2 fusions have been described.Hepatoblastoma is exceptionally rare in adults and can show a variety of histologic patterns which may cause diagnostic difficulty.Pancreatoblastoma,primarily a pediatric tumor,displays acinar differentiation and squamoid nests with other lines of differentiation also present,especially neuroendocrine.Diagnostic approaches for these blastomas include a combination of imaging modalities,histopathological examination,and molecular profiling.The treatment generally involves surgical resection,which may be supplemented by chemotherapy or radiotherapy in some cases.Prognoses vary with gastroblastoma generally showing favorable outcomes post-surgery whereas hepatoblastoma and pancreatoblastoma often have poorer outcomes,particularly in the setting of metastases.This review highlights the complexity of diagnosing and managing these rare adult blastomas as well as the need for ongoing research to better understand their pathogenesis and improve treatment strategies.

Molecular mechanisms underlying roles of long non-coding RNA small nucleolar RNA host gene 16 in digestive system cancers

This editorial reviews the molecular mechanisms underlying the roles of the long non-coding RNA(lncRNA)small nucleolar RNA host gene 16(SNHG16)in digestive system cancers based on two recent studies on lncRNAs in digestive system tumors.The first study,by Zhao et al,explored how hBD-1 affects colon cancer,via the lncRNA TCONS_00014506,by inhibiting mTOR and promoting autophagy.The second one,by Li et al,identified the lncRNA prion protein testis specific(PRNT)as a factor in oxaliplatin resistance by sponging ZNF184 to regulate HIPK2 and influence colorectal cancer progression and chemoresistance,suggesting PRNT as a potential therapeutic target for colorectal cancer.Both of these two articles discuss the mechanisms by which lncRNAs contribute to the development and progression of digestive system cancers.As a recent research hotspot,SNHG16 is a typical lncRNA that has been extensively studied for its association with digestive system cancers.The prevailing hypothesis is that SNHG16 participates in the development and progression of digestive system tumors by acting as a competing endogenous RNA,interacting with other proteins,regulating various genes,and affecting downstream target molecules.This review systematically examines the recently reported biological functions,related molecular mechanisms,and potential clinical significance of SNHG16 in various digestive system cancers,and explores the relationship between SNHG16 and digestive system cancers.The findings suggest that SNHG16 may serve as a potential biomarker and therapeutic target for human digestive system cancers.

Effect of comprehensive management combined with cognitive intervention on patient cooperation and complications during digestive endoscopy

BACKGROUND As lifestyles continue to change worldwide,the incidence of digestive tract carcinoma has gradually increased.Digestive endoscopy is an important tool that can assist in the diagnosis,treatment,and surgical intervention for this disease.However,the examination process is affected by many factors,and patient cooperation is often poor,which can increase the risk of complications.AIM To explore the effects of integrated management and cognitive intervention on cooperation and complications in patients undergoing endoscopy for early gastrointestinal neoplasms.METHODS A total of 354 patients with early stage gastrointestinal cancer who underwent digestive endoscopy procedures between January and December 2023 at our hospital were divided into observation and control groups(177 patients in each group)in a randomized controlled blind trial.The control group received routine interventions,while the observation group received comprehensive integrated management combined with cognitive interventions.We compared the changes in adverse mood,discomfort,examination time,cooperation with the examination,and complications before and after the intervention between the two groups.RESULTS The self-rated anxiety and depression scale scores were lower in the observation group than in the control group(P<0.05).The visual analog scale scores for discomfort during intubation and examination were also lower in the observation group than in the control group(P<0.05).Furthermore,the examination time was shorter in the observation group than in the control group(P<0.05),and the degree of cooperation(94.35%)was higher in the observation group than in the control group(84.75%;P<0.05).Lastly,the incidence rates of gastrointestinal adverse reactions(10.17%vs 20.34%),choking agitation(14.69%vs 24.86%),abdominal pain(8.47%vs 18.08%),and muscle tension(5.08%vs 14.12%)were all lower in the observation group than in the control group(P<0.05).CONCLUSION Integrated management and cognitive intervention in early gastrointestinal neoplasm endoscopy alleviate mood,reduce discomfort,shorten examinations,improve cooperation,and reduce complications.

Research Progress of Necroptosis in Digestive Diseases

Digestive system diseases refer to organic and functional disorders of the digestive system,which are prone to recurrence and frequently accompanied by multiple complications.Necroptosis is a regulated mode of cell death mediated by death receptors,dependent on receptor protein activation,and could be specifically inhibited by necrostatin-1.Necroptosis is involved in pathological and physiological processes of various diseases,and plays an important role in the growth and development of organisms and the homeostasis of organ tissues.This paper reviewed the research advancement of necroptosis in digestive system disorders,and discussed the relationship between necroptosis and digestive system diseases,aiming to provide theoretical basis for the cure of these diseases.

Digestive Surgical Emergencies at the “Mother Child”Hospital Center Luxembourg in Mali

Digestive surgical emergencies concern all patients admitted urgently, for whom a decision for surgical intervention may be necessary within 24 hours. They are on guard duty day and night. To carry out this work, we set ourselves the objectives of: 1) Studying digestive surgical emergencies in the general surgery department of the “Mother Child” Le Luxembourg hospital in Bamako, Mali;2) Determine the frequency of digestive surgical emergencies, 3) Describe the clinical and therapeutic aspects, and 4) Analyze the results of treatment. From November 1, 2022 to October 31, 2023, the general surgery department of the “Mother Child” Luxembourg Hospital Center in Bamako, Mali, carried out 139 digestive surgical emergencies whose files were usable;75 men and 64 women, a sex ratio of 1.2. The 20 - 40 years old age group was the most represented, at 40.29%. The average age was 39 years;the extremes 16 years and 93 years with a standard deviation of 21.65 years. The reference concerned 51.08% of our patients. Abdominal pain was the main reason for consultation (100% of cases). In the majority of cases, the physical examination made it possible to make the diagnosis. Faced with certain clinical cases, we requested ultrasound (109/139), ASP (46/139) and CT (15/139). The main etiology was acute appendicitis with 42.45% of cases. The frequency of digestive surgical emergencies was 10.71% of all activities in the general surgery department of the “Mère Enfant” Le Luxembourg hospital center in Bamako. All our patients were seen in consultation by an anesthesiologist before entering the operating room. The surgical consequences were complicated in 11.51% of cases with 7.91% deaths. Surgical site infections accounted for 12.5% of postoperative complications. Eleven deaths were noted, representing 68.75% of complications and 7.91% of our sample. Acute peritonitis was the cause of death in 100% of cases. The average cost of care was 329,000 FCFA.

Intestinal Microecology in Children with Pneumonia: The Relationship Between Digestive Health and Disease Recovery

This paper explores the association between intestinal microecology and digestive health and disease recovery in children with pneumonia.Intestinal microecological imbalance is common in children with pneumonia,which is closely associated with digestive health and disease recovery.Intestinal microecological imbalance may affect digestive enzyme activity,intestinal mucosal barrier function,and nutrient absorption,which in turn affects digestive health.In addition,intestinal microecological imbalances may be associated with immune regulation,inflammatory responses,and pathogen suppression,affecting disease recovery.Strategies to regulate intestinal microecology include probiotic supplementation,dietary modification,and pharmacological treatment.Currently,the study of intestinal microecology in children with pneumonia faces challenges,and there is a need for improved research methods,individualized treatment strategies,and the development of novel probiotics.In conclusion,the intestinal microecology of children with pneumonia is closely related to digestive health and disease recovery,and the regulation of intestinal microecology is of great significance to the treatment of children with pneumonia.Furthermore,future research should further explore the application of the microecology of the intestinal microecology in the treatment of children with pneumonia.

Investigation on quality of life of hospitalized patients in China with digestive system malignancy

Background:The purpose of this study is to evaluate the quality of life(QoL)of hospitalized patients in China suffering from digestive system malignancies and to identify potential risk factors for a decrease in QoL.Methods:The European Organization for Research and Treatment Core Quality of Life questionnaire(EORTC QLQ-C30)was applied to evaluate the QoL of 23,519 patients with six digestive malignancies(esophageal cancer,gastric cancer,colorectal cancer,liver cancer,biliary tract cancer,and pancreatic cancer).A t test or analysis of variance was employed to analyze the total EORTC QLQ-C30 scale scores and domain scores of the EORTC QLQ-C30 scale among patients in different subgroups.Results:The average QoL score was 50.4±10.8.The tumor type,age,sex,and TNM stage all had an impact on QoL ratings.Colorectal cancer patients had a better total QoL score(49.3±10.3)and scores in the domains of functioning,withmilder symptoms,except for diarrhea.Patients with biliary tract cancer(54.2±12.3)and pancreatic cancer(54.2±12.3)reported a poorer QoL,significant functional impairment,and more pronounced symptoms.Patients with esophageal cancer experienced the most severe financial difficulties(35.2±27.5).Patients aged≥65 years,women,and those with TNM stage III/IV reported lower QoL.In addition,the disparities in total QoL scores and scores in specific domains were significant among patients with some types of tumors,and based on ethnicity,educational level,occupation,treatment(s)received,and place of residence.Conclusions:There is a need to focus on elderly individuals,those with low educational levels,and patients with progressivemalignant tumors and to improve routine disease monitoring and symptom management to enhance the quality of life for patients with malignancies of the digestive system.

Effects of exercise by type and duration on quality of life in patients with digestive system cancers:A systematic review and network meta-analysis

Background:There is scant evidence regarding the effects of exercise type and duration on quality of life(QoL)in digestive system cancer(DSC)survivors.We aim to investigate the optimal type and duration of exercise to improve QoL for DSC survivors through a systematic review and network meta-analysis.Methods:A systematic literature search of PubMed,Embase,and Web of Science was performed.Eligibility for study inclusion was limited to studies that were randomized controlled trials involving all kinds of exercise in adult patients with DSCs,and the comparator was in standard care or other types of exercise.The primary outcome was QoL,including general health,physical health,mental health,and role function.Secondary outcomes included cancer-related symptoms such as fatigue,insomnia,depression,anxiety,and duration of hospital stay.The network meta-analyses were performed using a random-effect model.Results:The analysis included 32 eligible articles and a total of 2558 participants.Our primary outcome indicated that short-term aerobic exercise significantly enhanced general health(standardized mean difference(SMD)=0.66,95%credible intervals(Crls):0.05 to 1.30),and also contributed to a better mental health(SMD=0.38,95%CrI:-0.05 to 0.81)and role function(SMD=0.48,95%CrI:-0.27 to 1.20).Although without significant changes,short-term resistance exercise tended to increase the physical health of patients with DSCs(SM=0.69,95%CrI:-0.07 to 1.50)and effective in alleviating fatigue(SMD=-0.77,95%CrI:-1.50 to 0.01).Short-term aerobic exercise was related to a lower score of insomnia(SMD=-1.20,95%CrI:-2.40 to 0.06),depression(SMD=-0.51,95%CrI:-1.50 to 0.45),and anxiety(SMD=-0.45,95%CrI:-1.30 to 0.34).All types of exercise related to a trend of declined hospital stays(-0.87 to-5.00 day).Long-term resistance exercise,however,was negatively associated with general health(SMD=-0.33,95%CrI:-1.70 to 1.00),physical health(SMD=-0.18,95%CrI:-1.30to 0.90),and role function(SMD=-1.20,95%CrI:-2.50 to 0.11).Conclusion:This study suggests that short-term aerobic exercise,with or without resistance exercise programs,enhances QoL(especially for general health)as well as relieves cancer-related symptoms for DSC survivors,while long-term resistance exercise may have negative effects,and thus should be adopted cautiously.These results provide important evidence for the management of DSCs.

Optimal choice of stapler and digestive tract reconstruction method after distal gastrectomy for gastric cancer:A prospective case–control study

BACKGROUND Gastric cancer is the most common cause of cancer-related deaths,and is classified according to its location in the proximal,middle,or distal stomach.Surgical resection is the primary approach for treating gastric cancer.This prospective study aimed to determine the best reconstruction method after distal gastrectomy for gastric cancer.AIM To explore the efficacy of different staplers and digestive tract reconstruction(DTR)methods after radical gastrectomy and their influence on prognosis.METHODS Eighty-seven patients who underwent radical gastrectomy for distal gastric cancer at our institution between April 2017 and April 2020 were included in this study,with a follow-up period of 12-26 mo.The patients were assigned to four groups based on the stapler and DTR plan as follows:BillrothⅠ(B-I)reconstruction+linear stapler group(group A,22 cases),B-I reconstruction+circular stapler group(group B,22 cases),Billroth II(B-II)reconstruction+linear stapler group(group C,22 cases),and B-II reconstruction+circular stapler group(group D,21 cases).The pathological parameters,postoperative gastrointestinal function recovery,postoperative complications,and quality of life(QOL)were compared among the four groups.RESULTS No significant differences in the maximum diameter of the gastric tumors,total number of lymph nodes dissected,drainage tube removal time,QLQ(QOL questionnaire)-C30 and QLQ-STO22 scores at 1 year postoperatively,and incidence of complications were observed among the four groups(P>0.05).However,groups A and C(linear stapler)had significantly lower intraoperative blood loss and significantly shorter anastomosis time,operation time,first fluid diet intake time,first exhaust time,and length of postoperative hospital stay(P<0.05)than groups B and D(circular stapler).CONCLUSION Linear staplers offer several advantages for postoperative recovery.B-I and B-II reconstruction methods had similar effects on QOL.The optimal solution can be selected according to individual conditions and postoperative convenience.

Role of tumor-associated macrophages in common digestive system malignant tumors

Many digestive system malignant tumors are characterized by high incidence and mortality rate.Increasing evidence has revealed that the tumor microenvironment(TME)is involved in cancer initiation and tumor progression.Tumor-associated macrophages(TAMs)are a predominant constituent of the TME,and participate in the regulation of various biological behaviors and influence the prognosis of digestive system cancer.TAMs can be mainly classified into the antitumor M1 phenotype and protumor M2 phenotype.The latter especially are crucial drivers of tumor invasion,growth,angiogenesis,metastasis,immunosuppression,and resistance to therapy.TAMs are of importance in the occurrence,development,diagnosis,prognosis,and treatment of common digestive system malignant tumors.In this review,we summarize the role of TAMs in common digestive system malignant tumors,including esophageal,gastric,colorectal,pancreatic and liver cancers.How TAMs promote the development of tumors,and how they act as potential therapeutic targets and their clinical applications are also described.
