Analysis of 3 Serious Medication Errors in Provincial Hospital

Background: Medication errors are a common problem in Chinese hospital, with potentially harmful consequences for patients. The objective of this study was to analyze the cause of typical serious medication errors in some first-class provincial hospital to prevent medication error and improve rational use of drug and ensure patients administration security. Medication errors were collected between September 1, 2012 and August 31, 2013. 332 cases’ medication errors were categorized as harmful or not according to NCC MERP’s Index and other indexes such as type of error and causes of error. We focus on analyzing the 3 serious cases (0.9%, n = 3) among the all MEs that may have contributed to or resulted in temporary harm to the patient and required intervention, including the process and the cause and the background of the errors. The case analysis reminds us to pay more attention to prevent medication errors. The preventive medication error’s measures are explored through the analysis of the causes, such as forcing functions and constraints, automation and standardization, double-checking systems, rules and policies, information and more careful working. Conclusion: This analytical study demonstrates that medication error is an objective existent in hospital. It is especially important to ensure patient medication safety for reporting and analyzing medication error in order to explore measures preventing medication error.

Prevalence of HCV Antibody and its Associated Factors: A Study from Sentinel Hospitals in China

Objective The prevalence and related factors of serum anti-HCV in different regions and hospitals have not been studied extensively in China. We used routine screening data to determine the prevalence of HCV antibody in hospital patients, evaluate the epidemic trend of hepatitis C and formulate screening strategies.Methods Patient information and HCV antibody testing results were collected from January 2017 to December 2019 in 77 HCV sentinel hospitals in China. Univariate and multivariate logistic regression was used to determine the characteristics and associations.Results HCV antibody prevalence rates were distinct among patients in different departments, with a range of 0.33%–6.93%. Patients who were admitted to the liver disease-related departments(aOR =10.76;95% CI, 10.27–11.28), Internal Medicine(aOR = 2.87;95% CI, 2.75–3.00), and Department of Surgery(aOR = 1.95;95% CI, 1.87–2.04), were more likely to be tested for HCV antibody positive. HCV antibody prevalence was associated with patients aged 45 years and older(aOR = 2.74;95% CI,2.69–2.80), testing in infetious disease hospitals(aOR = 2.33;95% CI, 2.26–2.40) and secondary hospitals(aOR = 1.72;95% CI, 1.69–1.75). Patients in sentinel hospitals of the Northeast(aOR = 12.75;95% CI,12.40–13.11), the Central(aOR = 1.65;95% CI, 1.61–1.70), and the West(aOR = 1.78;95% CI, 1.73–1.83)China had higher HCV prevalence than those who were in the Eastern coastal area. Conclusion Those who were over 45 years old and saw doctors for liver diseases, and invasive diagnosis and treatment should be referred to HCV antibody testing.

Low expression of fatty acid oxidation related gene ACADM indicates poor prognosis of renal clear cell carcinoma and is related to tumor immune infltration

This research aims to identify the key fatty acid beta-oxidation(FAO)genes that are altered in kidney renal clear cell carcinoma(KIRC)and to analyze the role of these genes in KIRC The Gene Expression Omnibus(GEO)and FAO datasets were used to identify these key genes.Wilcoxon rank sum test was used to assess the levels of acyl-CoA dehydrogenase medium chain(ACADM)between KIRC and non cancer samples.The logistic regression and Wilcoxon rank sum test were used to explore the association between ACADM and clinical features.The diagnostic performance of ACADM for KIRC was asessed using a diagnostic receiver operating ch aracteristic(ROC)curve.The co-expressed genes of ACADM were identifed in LinkedOmics database,and their function and pathway enrichment were analyzed.The correlation between ACADM expression level and immune infitration was analyzed by Gene Set Variation Analysis(GSVA)method Additionally,the proliferation,migration,and invasion abilities of KIRC cells were assessed after overexpressing ACADM.Following differential analysis and intersection,we identifed six hub genes,induding ACADM.We found that the expression level of ACADM was decreased in KIRC tissues and had a better diagnostic efect(AUC=0.916).Survival analysis suggested that patients with decreased ACADM expression had a worse prognosis.According to correlation analysis,a variety of dinical features were associated with the expression level of ACADML By analyzing the infiltration level of immune cells,we found that ACADM may be related to the enrichment of immune cells.Finally,ACADM overexpression inhibited proliferation,migration,and invasion of KIRC cells.In conclusion,our findings suggest that reduced ACADM expression in KIRC patients is indicative of poor prognosis.These results imply that ACADM may be a diagnostic and prognostic marker for individuals with KIRC,offering a reference for dinicians in diagnosis and treatment.

Diagnostic Value of GDF10 for the Tumorigenesis and Immune Infiltration in Lung Squamous Cell Carcinoma

Objective:Lung squamous cell carcinoma(LUSC)is associated with a low survival rate.Evidence suggests that bone morphogenetic proteins(BMPs)and their receptors(BMPRs)play crucial roles in tumorigenesis and progression.However,a comprehensive analysis of their role in LUSC is lacking.Our study aimed to explore the relationship between BMPs/BMPRs expression levels and the tumorigenesis and prognosis of LUSC.Methods:The“R/Limma”package was utilized to analyze the differential expression characteristics of BMPs/BMPRs in LUSC,using data from TCGA,GTEx,and GEO databases.Concurrently,the“survminer”packages were employed to investigate their prognostic value and correlation with clinical features in LUSC.The core gene associated with LUSC progression was further explored through weighted gene correlation network analysis(WGCNA).LASSO analysis was conducted to construct a prognostic risk model for LUSC.Clinical specimens were examined by immunohistochemical analysis to confirm the diagnostic value in LUSC.Furthermore,based on the tumor immune estimation resource database and tumor-immune system interaction database,the role of the core gene in the tumor microenvironment of LUSC was explored.Results:GDF10 had a significant correlation only with the pathological T stage of LUSC,and the protein expression level of GDF10 decreased with the tumorigenesis of LUSC.A prognostic risk model was constructed with GDF10 as the core gene and 5 hub genes(HRASLS,HIST1H2BH,FLRT3,CHEK2,and ALPL)for LUSC.GDF10 showed a significant positive correlation with immune cell infiltration and immune checkpoint expression.Conclusion:GDF10 might serve as a diagnostic biomarker reflecting the tumorigenesis of LUSC and regulating the tumor immune microenvironment to guide more effective treatment for LUSC.

Characteristics and risk factor analyses of high-grade intraepithelial neoplasia in older patients with colorectal polyps

BACKGROUND According to the degree of intradermal neoplasia in the colorectal exhalation,it can be divided into two grades:Low-grade intraepithelial neoplasia(LGIN)and high-grade intraepithelial neoplasia(HGIN).Currently,it is difficult to accurately diagnose LGIN and HGIN through imaging,and clinical diagnosis depends on postoperative histopathological diagnosis.A more accurate method for evaluating HGIN preoperatively is urgently needed in the surgical treatment and nursing intervention of colorectal polyps.AIM To explore the characteristics and risk factors of HGIN in older patients with colorectal polyps.METHODS We selected 84 older patients diagnosed with HGIN as the HGIN group(n=95 colonic polyps)and 112 older patients diagnosed with LGIN as the LGIN group(n=132 colonic polyps)from Shandong Provincial Hospital Affiliated to Shandong First Medical University.The endoscopic features,demographic characteristics,and clinical manifestations of the two patient groups were compared,and a logistic regression model was used to analyze the risk factors for HGIN in these patients.RESULTS The HGIN group was older and had a higher number of sigmoid colon polyps,rectal polyps,pedunculated polyps,polyps≥1.0 cm in size,polyps with surface congestion,polyps with surface depression,and polyps with villous/tubular adenomas,a higher proportion of patients with diabetes and a family history of colorectal cancer,patients who experienced rectal bleeding or occult blood,patients with elevated carcinoembryonic antigen(CEA)and cancer antigen 199(CA199),and lower nutritional levels and higher frailty levels.The polyp location(in the sigmoid colon or rectum),polyp diameter(≥1.0 cm),pathological diagnosis of(villous/tubular adenoma),family history of colorectal cancer,rectal bleeding or occult blood,elevated serum CEA and CA199 levels,lower nutritional levels and higher frailty levels also are independent risk factors for HGIN.CONCLUSION The occurrence of high-grade neoplastic transformation in colorectal polyps is closely associated with their location,size,villous/tubular characteristics,family history,elevated levels of tumor markers,and lower nutritional levels and higher frailty levels.

On implications of somatostatin in diabetic retinopathy

Somatostatin,a naturally produced neuroprotective peptide,depresses excitatory neurotransmission and exerts anti-proliferative and anti-inflammatory effects on the retina.In this review,we summarize the progress of somatostatin treatment of diabetic retinopathy through analysis of relevant studies published from February 2019 to February 2023 extracted from the PubMed and Google Scholar databases.Insufficient neuroprotection,which occurs as a consequence of declined expression or dysregulation of retinal somatostatin in the very early stages of diabetic retinopathy,triggers retinal neurovascular unit impairment and microvascular damage.Somatostatin replacement is a promising treatment for retinal neurodegeneration in diabetic retinopathy.Numerous pre-clinical and clinical trials of somatostatin analog treatment for early diabetic retinopathy have been initiated.In one such trial(EUROCONDOR),topical administration of somatostatin was found to exert neuroprotective effects in patients with pre-existing retinal neurodysfunction,but had no impact on the onset of diabetic retinopathy.Overall,we concluded that somatostatin restoration may be especially beneficial for the growing population of patients with early-stage retinopathy.In order to achieve early prevention of diabetic retinopathy initiation,and thereby salvage visual function before the appearance of moderate non-proliferative diabetic retinopathy,several issues need to be addressed.These include the needs to:a)update and standardize the retinal screening scheme to incorporate the detection of early neurodegeneration,b)identify patient subgroups who would benefit from somatostatin analog supplementation,c)elucidate the interactions of somatostatin,particularly exogenously-delivered somatostatin analogs,with other retinal peptides in the context of hyperglycemia,and d)design safe,feasible,low cost,and effective administration routes.

Association between gut microbiota and hepatocellular carcinoma and biliary tract cancer:A mendelian randomization study

BACKGROUND An increasing number of studies have begun to discuss the relationship between gut microbiota and diseases,yet there is currently a lack of corresponding articles describing the association between gut microbiota and hepatocellular carcinoma(HCC)and biliary tract cancer(BTC).This study aims to explore the relationship between them using Mendelian randomization(MR)analysis method.AIM To assess the relationship between gut microbiota and HCC and BTC.METHODS We obtained Genome-wide association study(GWAS)data for the gut microbiome from the intestinal microbiota genomic library(MiBioGen,https://mibiogen.gcc.rug.nl/).Additionally,we accessed data pertaining to HCC and BTC from the IEU open GWAS platform(https://gwas.mrcieu.ac.uk/).Our analysis employed fundamental instrumental variable analysis methods,including inverse-variance weighted,MR and Egger.To ensure the dependability of the results,we subjected the results to tests for multiple biases and heterogeneity.RESULTS During our investigation,we discovered 11 gut microbiota linked to an increased risk to BTC and HCC.The former included the genus Eubacterium hallii group(P=0.017),Candidatus Soleaferrea(P=0.034),Flavonifractor(P=0.021),Lachnospiraceae FCS020(P=0.034),the order Victivallales(P=0.018),and the class Lentisphaeria(P=0.0.18).The latter included the genus Desulfovibrio(P=0.042),Oscillibacter(P=0.023),the family Coriobacteriaceae(P=0.048),the order Coriobacteriales(P=0.048),and the class Coriobacteriia(P=0.048).Furthermore,in BTC,we observed 2 protective gut microbiota namely the genus Dorea(P=0.041)and Lachnospiraceae ND3007 group(P=0.045).All results showed no evidence of multiplicity or heterogeneity.CONCLUSION This study explores a causal link between gut microbiota and HCC and BTC.These insights may enhance the mechanistic knowledge of microbiota-related HCC and BTC pathways,potentially informing therapeutic strategies.

Identification of risk factors and construction of a nomogram predictive model for post-stroke infection in patients with acute ischemic stroke

BACKGROUND Post-stroke infection is the most common complication of stroke and poses a huge threat to patients.In addition to prolonging the hospitalization time and increasing the medical burden,post-stroke infection also significantly increases the risk of disease and death.Clarifying the risk factors for post-stroke infection in patients with acute ischemic stroke(AIS)is of great significance.It can guide clinical practice to perform corresponding prevention and control work early,minimizing the risk of stroke-related infections and ensuring favorable disease outcomes.AIM To explore the risk factors for post-stroke infection in patients with AIS and to construct a nomogram predictive model.METHODS The clinical data of 206 patients with AIS admitted to our hospital between April 2020 and April 2023 were retrospectively collected.Baseline data and post-stroke infection status of all study subjects were assessed,and the risk factors for poststroke infection in patients with AIS were analyzed.RESULTS Totally,48 patients with AIS developed stroke,with an infection rate of 23.3%.Age,diabetes,disturbance of consciousness,high National Institutes of Health Stroke Scale(NIHSS)score at admission,invasive operation,and chronic obstructive pulmonary disease(COPD)were risk factors for post-stroke infection in patients with AIS(P<0.05).A nomogram prediction model was constructed with a C-index of 0.891,reflecting the good potential clinical efficacy of the nomogram prediction model.The calibration curve also showed good consistency between the actual observations and nomogram predictions.The area under the receiver operating characteristic curve was 0.891(95%confidence interval:0.839–0.942),showing predictive value for post-stroke infection.When the optimal cutoff value was selected,the sensitivity and specificity were 87.5%and 79.7%,respectively.CONCLUSION Age,diabetes,disturbance of consciousness,NIHSS score at admission,invasive surgery,and COPD are risk factors for post-stroke infection following AIS.The nomogram prediction model established based on these factors exhibits high discrimination and accuracy.

Changes in posterior corneal elevation after small incision lenticule extraction for different myopic diopters

●AIM:To study the changes and effect factors of posterior corneal surface after small incision lenticule extraction(SMILE)with different myopic diopters.●METHODS:Ninety eyes of 90 patients who underwent SMILE were included in this retrospective study.Patients were allocated into three groups based on the preoperative spherical equivalent(SE):low myopia(SE≥-3.00 D),moderate myopia(-3.00 D>SE>-6.00 D)and high myopia(SE≤-6.00 D).Posterior corneal surfaces were measured by a Scheimpflug camera preoperatively and different postoperative times(1wk,1,3,6mo,and 1y).Posterior mean elevation(PME)at 25 predetermined points of 3 concentric circles(2-,4-,and 6-mm diameter)above the best fit sphere was analyzed.●RESULTS:All surgeries were completed uneventfully and no ectasia was found through the observation.The difference of myopia group was significant at the 2-mm ring at 1 and 3mo postoperatively(1mo:P=0.017;3mo:P=0.018).The effect of time onΔPME was statistically significant(2-mm ring:P=0.001;4-mm ring:P<0.001;6-mm ring:P<0.001).The effect of different corneal locations onΔPME was significant except 1wk postoperatively(1mo:P=0.000;3mo:P=0.000;6mo:P=0.001;1y:P=0.001).Posterior corneal stability was linearly correlated with SE,central corneal thickness,ablation depth,residual bed thickness,percent ablation depth and percent stromal bed thickness.●CONCLUSION:The posterior corneal surface changes dynamically after SMILE.No protrusion is observed on the posterior corneal surface in patients with different degrees of myopia within one year after surgery.SMILE has good stability,accuracy,safety and predictability.

In Situ Raman Monitoring of Trace Antibiotics in Different Harsh Water Environments

In situ surface-enhanced Raman scattering(SERS)is a widely used operando analytical technique,while facing numerous complex factors in applications under aqueous environment,such as low detection sensitivity,poor anti-interference capability,etc.,resulting in unreliable detectability.To address these issues,herein a new hydrophobic SERS strategy has been attempted.By comprehensively designing and researching a SERS-active structure of superhydrophobic ZnO/Ag nanowires,we demonstrate that hydrophobicity can not only draw analytes from water onto substrate,but also adjust"hottest spot"from the bottom of the nanowires to the top.As a result,the structure can simultaneously concentrate the dispersed molecules in water and the enhanced electric field in structure into a same zone,while perfecting its own anti-interference ability.The underwater in situ analytical enhancement factor of this platform is as high as 1.67×10^(11),and the operando limited of detection for metronidazole(MNZ)reaches to 10^(-9)M.Most importantly,we also successfully generalized this structure to various real in situ detection scenarios,including on-site detection of MNZ in corrosive urine,real-time warning of wrong dose of MNZ during intravenous therapy,in situ monitoring of MNZ in flowing wastewater with particulate interference,etc.,demonstrating the great application potential of this hydrophobic platform.This work realizes a synergistic promotion for in situ SERS performance under aqueous environment,and also provides a novel view for improving other in situ analytical techniques.

Computed tomography-based radiomics combined with machine learning allows differentiation between primary intestinal lymphoma and Crohn's disease

BACKGROUND Due to similar clinical manifestations and imaging signs,differential diagnosis of primary intestinal lymphoma(PIL)and Crohn's disease(CD)is a challenge in clinical practice.AIM To investigate the ability of radiomics combined with machine learning methods to differentiate PIL from CD.METHODS We collected contrast-enhanced computed tomography(CECT)and clinical data from 120 patients form center 1.A total of 944 features were extracted singlephase images of CECT scans.Using the last absolute shrinkage and selection operator model,the best predictive radiographic features and clinical indications were screened.Data from 54 patients were collected at center 2 as an external validation set to verify the robustness of the model.The area under the receiver operating characteristic curve,accuracy,sensitivity and specificity were used for evaluation.RESULTS A total of five machine learning models were built to distinguish PIL from CD.Based on the results from the test group,most models performed well with a large area under the curve(AUC)(>0.850)and high accuracy(>0.900).The combined clinical and radiomics model(AUC=1.000,accuracy=1.000)was the best model among all models.CONCLUSION Based on machine learning,a model combining clinical data with radiologic features was constructed that can effectively differentiate PIL from CD.

Assessment of pathogenicity and functional characterization of APPL1 gene mutations in diabetic patients

BACKGROUND Adaptor protein,phosphotyrosine interacting with PH domain and leucine zipper 1(APPL1)plays a crucial role in regulating insulin signaling and glucose metabolism.Mutations in the APPL1 gene have been associated with the development of maturity-onset diabetes of the young type 14(MODY14).Currently,only two mutations[c.1655T>A(p.Leu552*)and c.281G>A p.(Asp94Asn)]have been identified in association with this disease.Given the limited understanding of MODY14,it is imperative to identify additional cases and carry out comprehensive research on MODY14 and APPL1 mutations.AIM To assess the pathogenicity of APPL1 gene mutations in diabetic patients and to characterize the functional role of the APPL1 domain.METHODS Patients exhibiting clinical signs and a medical history suggestive of MODY were screened for the study.Whole exome sequencing was performed on the patients as well as their family members.The pathogenicity of the identified APPL1 variants was predicted on the basis of bioinformatics analysis.In addition,the pathogenicity of the novel APPL1 variant was preliminarily evaluated through in vitro functional experiments.Finally,the impact of these variants on APPL1 protein expression and the insulin pathway were assessed,and the potential mechanism underlying the interaction between the APPL1 protein and the insulin receptor was further explored.RESULTS A total of five novel mutations were identified,including four missense mutations(Asp632Tyr,Arg633His,Arg532Gln,and Ile642Met)and one intronic mutation(1153-16A>T).Pathogenicity prediction analysis revealed that the Arg532Gln was pathogenic across all predictions.The Asp632Tyr and Arg633His variants also had pathogenicity based on MutationTaster.In addition,multiple alignment of amino acid sequences showed that the Arg532Gln,Asp632Tyr,and Arg633His variants were conserved across different species.Moreover,in in vitro functional experiments,both the c.1894G>T(at Asp632Tyr)and c.1595G>A(at Arg532Gln)mutations were found to downregulate the expression of APPL1 on both protein and mRNA levels,indicating their pathogenic nature.Therefore,based on the patient’s clinical and family history,combined with the results from bioinformatics analysis and functional experiment,the c.1894G>T(at Asp632Tyr)and c.1595G>A(at Arg532Gln)mutations were classified as pathogenic mutations.Importantly,all these mutations were located within the phosphotyrosinebinding domain of APPL1,which plays a critical role in the insulin sensitization effect.CONCLUSION This study provided new insights into the pathogenicity of APPL1 gene mutations in diabetes and revealed a potential target for the diagnosis and treatment of the disease.

Preventive effect of probiotics on infections following colorectal cancer surgery:An umbrella meta-analysis

BACKGROUND Postoperative infections remain a significant source of morbidity among patients undergoing colorectal cancer(CRC)surgery.While probiotics have been pro-posed as a potential strategy to mitigate the risk of these infections,contemporary meta-analyses have produced conflicting findings.AIM To synthesize the available evidence regarding the prophylactic efficacy of probiotics in preventing infections following CRC surgery.METHODS A comprehensive search of PubMed and Scopus was conducted to identify relevant meta-analyses published up to February 2024.To assess the efficacy of probiotics on outcomes,relative risks(RR)and their corresponding 95%CI were pooled using a random effects model.RESULTS This comprehensive umbrella meta-analysis integrated eleven meta-analyses encompassing 11518 participants who fulfilled the inclusion criteria.Probiotics administration resulted in a statistically significant reduction in the incidence of total infections(RR:0.40,95%CI:0.31-0.51;moderate certainty),surgical site infections(RR:0.56,95%CI:0.49-0.63;high certainty),pneumonia(RR:0.38,95%CI:0.30-0.48;high certainty),urinary tract infections(RR:0.44,95%CI:0.31-0.61;moderate certainty),bacteremia(RR:0.41,95%CI:0.30-0.56;high certainty),and sepsis(RR:0.35,95%CI:0.25-0.44;high certainty).However,probiotics did not significantly affect intra-abdominal,central line,or peritoneal infections.CONCLUSION Probiotics have demonstrated potential in mitigating postoperative infectious complications among patients undergoing CRC surgery.

Pleural effusion,ascites,colon ulcers and hematochezia:What we can learn from the diagnostic process of a patient with plasma cell myeloma:A case report

BACKGROUND Plasma cell myeloma(PCM)is characterized by hypercalcemia,renal impairment,anemia,and bone destruction.While pleural effusion,ascites,abdominal pain,and bloody stool are common manifestations of lung disease or gastrointestinal disorders,they are rarely observed in patients with PCM.CASE SUMMARY A 66-year-old woman presented with complaints of recurrent chest tightness,wheezing,and abdominal bloating accompanied by bloody stools.Computed tomography revealed pleural effusion and ascites.Pleural effusion tests showed inflammation,but the T-cell spot test and carcinoembryonic antigen were negative.Endoscopy showed colonic mucosal edema with ulcer formation and local intestinal lumen stenosis.Echocardiography revealed enlarged atria and reduced left ventricular systolic function.The diagnosis remained unclear.Further testing revealed elevated blood light chain lambda and urine immunoglobulin levels.Blood immunofixation electrophoresis was positive for immunoglobulin G lambda type.Smear cytology of the bone marrow showed a high proportion of plasma cells,accounting for about 4.5%.Histopathological examination of the bone marrow suggested PCM.Flow cytometry showed abnormal plasma cells with strong expression of CD38,CD138,cLambda,CD28,CD200,and CD117.Fluorescence in situ hybridization gene testing of the bone marrow suggested 1q21 gene amplification,but cytogenetic testing showed no clonal abnormalities.Colonic mucosa and bone marrow biopsy tissues were negative for Highman Congo red staining.The patient was finally diagnosed with PCM.CONCLUSION A diagnosis of PCM should be considered in older patients with pleural effusion,ascites,and multi-organ injury.

Hemoglobin loss method calculates blood loss during pancreaticoduodenectomy and predicts bleeding-related risk factors

BACKGROUND The common clinical method to evaluate blood loss during pancreaticoduoden-ectomy(PD)is visual inspection,but most scholars believe that this method is extremely subjective and inaccurate.Currently,there is no accurate,objective me-thod to evaluate the amount of blood loss in PD patients.We retrospectively analyzed the clinical data of 341 patients who underwent PD in Shandong Provincial Hospital from March 2017 to February 2019.According to different surgical methods,they were divided into an open PD(OPD)group and a laparoscopic PD(LPD)group.The differences and correlations between the in-traoperative estimation of blood loss(IEBL)obtained by visual inspection and the intraoperative calculation of blood loss(ICBL)obtained using the Hb loss method were analyzed.ICBL,IEBL and perioperative calculation of blood loss(PCBL)were compared between the two groups,and single-factor regression analysis was performed.RESULTS There was no statistically significant difference in the preoperative general patient information between the two groups(P>0.05).PD had an ICBL of 743.2(393.0,1173.1)mL and an IEBL of 100.0(50.0,300.0)mL(P<0.001).There was also a certain correlation between the two(r=0.312,P<0.001).Single-factor analysis of ICBL showed that a history of diabetes[95%confidence interval(CI):53.82-549.62;P=0.017]was an independent risk factor for ICBL.In addition,the single-factor analysis of PCBL showed that body mass index(BMI)(95%CI:0.62-76.75;P=0.046)and preoperative total bilirubin>200μmol/L(95%CI:7.09-644.26;P=0.045)were independent risk factors for PCBL.The ICBLs of the LPD group and OPD group were 767.7(435.4,1249.0)mL and 663.8(347.7,1138.2)mL,respectively(P>0.05).The IEBL of the LPD group 200.0(50.0,200.0)mL was slightly greater than that of the OPD group 100.0(50.0,300.0)mL(P>0.05).PCBL was greater in the LPD group than the OPD group[1061.6(612.3,1632.3)mL vs 806.1(375.9,1347.6)mL](P<0.05).CONCLUSION The ICBL in patients who underwent PD was greater than the IEBL,but there is a certain correlation between the two.The Hb loss method can be used to evaluate intraoperative blood loss.A history of diabetes,preoperative bilirubin>200μmol/L and high BMI increase the patient's risk of bleeding.

Robotic-assisted low anterior resection for rectal cancer shows similar clinical efficacy to laparoscopic surgery: A propensity score matched study

BACKGROUND Rectal cancer ranks as the second leading cause of cancer-related mortality worldwide,necessitating surgical resection as the sole treatment option.Over the years,there has been a growing adoption of minimally invasive surgical techni-ques such as robotic and laparoscopic approaches.Robotic surgery represents an innovative modality that effectively addresses the limitations associated with traditional laparoscopic techniques.While previous studies have reported favo-rable perioperative outcomes for robot-assisted radical resection in rectal cancer patients,further evidence regarding its oncological safety is still warranted.AIM To conduct a comparative analysis of perioperative and oncological outcomes between robot-assisted and laparoscopic-assisted low anterior resection(LALAR)procedures.METHODS The clinical data of 125 patients who underwent robot-assisted low anterior resection(RALAR)and 279 patients who underwent LALAR resection at Shandong Provincial Hospital Affiliated to Shandong First Medical University from December 2019 to November 2022 were retrospectively analyzed.After performing a 1:1 propensity score matching,the patients were divided into two groups:The RALAR group and the LALAR group(111 cases in each group).Subsequently,a comparison was made between the short-term outcomes within 30 d after surgery and the 3-year survival outcomes of these two groups.RESULTS Compared to the LALAR group,the RALAR group exhibited a significantly earlier time to first flatus[2(2-2)d vs 3(3-3)d,P=0.000],as well as a shorter time to first fluid diet[4(3-4)d vs 5(4-6)d,P=0.001].Additionally,the RALAR group demonstrated reduced postoperative indwelling catheter time[2(1-3)d vs 4(3-5)d,P=0.000]and decreased length of hospital stay after surgery[5(5-7)d vs 7(6-8)d,P=0.009].Moreover,there was an observed increase in total cost of hospitalization for the RALAR group compared to the LALAR group[10777(10780-11850)dollars vs 10550(8766-11715)dollars,P=0.012].No significant differences were found in terms of conversion rate to laparotomy or incidence of postoperative complications between both groups.Furthermore,no significant disparities were noted regarding the 3-year overall survival rate and 3-year disease-free survival rate between both groups.CONCLUSION Robotic surgery offers potential advantages in terms of accelerated recovery of gastrointestinal and urologic function compared to LALAR resection,while maintaining similar perioperative and 3-year oncological outcomes.

Adenylate cyclase activates the cAMP signalling pathway to enhance platelet-rich plasma-treated Achilles tendon disease,a theoretical bioinformatics-based study

The effectiveness of platelet-rich plasma(PRP)for the treatment of Achilles tendon disorders still needs to be evaluated through a series of prospective studies,but genomic analysis can reveal the existence of complementary PRP treatment options.Based on the 96 platelet activation-related genes in the Kyoto Encyclopedia of Genes and Genomes(KEGG)database,we performed Gene Ontology functional enrichment analysis and KEGG enrichment analysis,pathway correlation analysis,and enrichment mapping to determine the enrichment results of the gene set enrichment analysis and found that the cAMP signalling pathway may be the key to enhancing the effectiveness of PRP treatment.The cAMP signalling pathway interacts with the Rap1 signalling pathway and cGMPPKG signalling pathway to mediate the entire pathophy-siological process of Achilles tendon disease.Moreover,ADCY1-9 may be the key to the activation of the cAMP signalling network.Further based on the data in the Gene Expression Omnibus database,it was found that ADCY4 and ADCY7 may be the players that play a major role,associated with the STAT4-ADCY4-LAMA5 axis and the GRbeta-ADCY7-SEMA3C axis,which is expected to be a complementary target for enhancing the efficacy of PRP in the treatment of Achilles tendon disease.

Erythropoietin-induced hepatocyte receptor A2 regulates effect of pyroptosis on gastrointestinal colorectal cancer occurrence and metastasis resistance

Erythropoietin-induced hepatocyte receptor A2(EphA2)is a receptor tyrosine kinase that plays a key role in the development and progression of a variety of tumors.This article reviews the expression of EphA2 in gastrointestinal(GI)colorectal cancer(CRC)and its regulation of pyroptosis.Pyroptosis is a form of programmed cell death that plays an important role in tumor suppression.Studies have shown that EphA2 regulates pyrodeath through various signaling pathways,affecting the occurrence,development and metastasis of GI CRC.The overexpression of EphA2 is closely related to the aggressiveness and metastasis of GI CRC,and the inhibition of EphA2 can induce pyrodeath and improve the sensitivity of cancer cells to treatment.In addition,EphA2 regulates intercellular communication and the microenvironment through interactions with other cytokines and receptors,further influencing cancer progression.The role of EphA2 in GI CRC and its underlying mechanisms provide us with new perspectives and potential therapeutic targets,which have important implications for future cancer treatment.

Novel subtype of obesity influencing the outcomes of sleeve gastrectomy:Familial aggregation of obesity

BACKGROUND Differences in the preoperative characteristics and weight loss outcomes after sleeve gastrectomy(SG)between patients with familial aggregation of obesity(FAO)and patients with sporadic obesity(SO)have not been elucidated.AIM To explore the impact of SG on weight loss and the alleviation of obesity-related comorbidities in individuals with FAO.METHODS A total of 193 patients with obesity who underwent SG were selected.Patients with FAO/SO were matched 1:1 by propensity score matching and were categorized into 4 groups based on the number of first-degree relatives with obesity(1 SO vs 1FAO,2SO vs 2FAO).The baseline characteristics,weight loss outcomes,prevalence of obesity-related comorbidities and incidence of major surgeryrelated complications were compared between groups.RESULTS We defined FAO as the presence of two or more first-degree relatives with obesity.Patients with FAO did not initially show significant differences in baseline data,short-term postoperative weight loss,or obesity-related comorbidities when compared to patients with SO preoperatively.However,distinctions between the two groups became evident at the two-year mark,with statistically significant differences in both percentage of total weight loss(P=0.006)and percentage of excess weight loss(P<0.001).The FAO group exhibited weaker remission of type 2 diabetes mellitus(T2DM)(P=0.031),hyperlipidemia(P=0.012),and non-alcoholic fatty liver disease(NAFLD)(P=0.003)as well as a lower incidence of acid reflux(P=0.038).CONCLUSION FAO patients is associated with decreased mid-to-long-term weight loss outcomes;the alleviation of T2DM,hyperlipidemia and NAFLD;and decreased incidence of acid reflux postoperatively.
