Traditional centrality measures often fall short in capturing the multifaceted roles of nodes within these networks. The Page Rank algorithm, widely recognized for ranking web pages, offers a more nuanced approach by considering the importance of connected nodes. However, existing methods generally overlook the geometric properties of networks, which can provide additional insights into their structure and functionality. In this paper, we propose a novel method named Curv-Page Rank(C-PR), which integrates network curvature and Page Rank to identify influential nodes in complex networks. By leveraging the geometric insights provided by curvature alongside structural properties, C-PR offers a more comprehensive measure of a node's influence. Our approach is particularly effective in networks with community structures, where it excels at pinpointing bridge nodes critical for maintaining connectivity and facilitating information flow. We validate the effectiveness of C-PR through extensive experiments. The results demonstrate that C-PR outperforms traditional centrality-based and Page Rank methods in identifying critical nodes. Our findings offer fresh insights into the structural importance of nodes across diverse network configurations, highlighting the potential of incorporating geometric properties into network analysis.展开更多

Advances in SLN detection have been very important in refining surgical techniques and improving patient outcomes. The purpose of the present study is to compare the effectiveness of radiocolloids, blue dyes, and fluorescent tracers in detecting the sentinel lymph node in breast cancer. Materials and Methods: Specifically, we analyzed the detection rate, accuracy, and safety profile of the techniques to outline the most reliable and clinically available. A comprehensive review was conducted, searching key databases, including PubMed, Scopus, and Web of Science, for studies published between 2010 and 2024. The review focused on studies that compared the performance of radiocolloids, blue dyes, and fluorescent tracers in the detection of sentinel lymph nodes in breast cancer patients. A total of 54 studies were included based on specific inclusion criteria. Results: Radiocolloids showed high detection rates in studies. Blue dyes have comparable results, but a small percentage of allergic reactions has been observed. Fluorescent tracers such as indocyanine green have improved visualization and accuracy, but their use requires specialized equipment and expertise. Combining radiocolloids with blue dyes or fluorescent tracers has improved detection rates in several studies. Cost and accessibility challenges have also been pointed out, particularly in low-resource settings. Conclusions: Radiocolloids have attained the status of gold standard in the detection of SLNs in breast cancer for their reliability and accuracy. While combined use with other tracers, like blue dyes or fluorescent agents, enhances overall detection performance, making it more holistic. As expected, further innovation and effort are required to improve accessibility and optimize the technique of sentinel lymph node biopsy worldwide.展开更多

Improvement of stroke care should be achieved through awareness of public, especially through high-risk group. Henceforth, the aim of this study was to evaluate the effect of nursing intervention on improving awareness of high-risk people about stroke prevention. Methods: A quasi-experimental design was used to carry out this study, where a purposive sample of 80 adult patients at high risk for stroke were enrolled while they were attending the out-patient clinics of Zagazig University Hospitals for follow-up treatment;they were divided into two groups: case (40 patients) and control (40 patients). An interview questionnaire was used to assess patients’ knowledge regarding warning signs, risk factors, and immediate treatment;attitude;and their practice for prevention for stroke at pretest and posttest. Results: The study revealed the poor level of knowledge, bad level of preventive behavior, and negative attitude regarding stroke prevention at pre-intervention. However, after intervention, the high-risk people had fair level of knowledge with moderate practice for stroke prevention and positive attitude, with statistically significant difference between pre-post intervention and between the case and control groups. Conclusions: The study revealed that the nursing intervention seemed to change the knowledge, practice, and attitude of subjects regarding stroke prevention. This, in turn, implies that awareness of prevention of stroke and high-risk factor control could be important to reduce the burden of stroke in Egypt. Thus, further research on a larger scale is required to improve population knowledge and behavior for stroke prevention and control.展开更多

文摘BACKGROUND One of the main characteristics of oral squamous cell carcinoma(OSCC)is that it metastasizes to cervical lymph nodes frequently with a high degree of local invasiveness.A primary feature of malignant tumors is their penetration of neighboring tissues,such as lymphatic and blood arteries,due to the tumor cells'capacity to break down the extracellular matrix(ECM).Matrix metalloproteinases(MMPs)constitute a family of proteolytic enzymes that facilitate tissue remodeling and the degradation of the ECM.MMP-9 and MMP-13 belong to the group of extracellular matrix degrading enzymes and their expression has been studied in OSCC because of their specific functions.MMP-13,a collagenase family member,is thought to play an essential role in the MMP activation cascade by breaking down the fibrillar collagens,whereas MMP-9 is thought to accelerate the growth of tumors.Elevated MMP-13 expression has been associated with tumor behavior and patient prognosis in a number of malignant cases.AIM To assess the immunohistochemical expression of MMP-9 and MMP-13 in OSCC.METHODS A total of 40 cases with histologically confirmed OSCC by incisional biopsy were included in this cross-sectional retrospective study.The protocols for both MMP-9 and MMP-13 immunohistochemical staining were performed according to the manufacturer’s recommendations along with the normal gingival epithelium as a positive control.All the observations were recorded and Pearson’sχ²test with Fisher exact test was used for statistical analysis.RESULTS Our study showed no significant correlation between MMP-9 and MMP-13 staining intensity and tumor size.The majority of the patients were in advanced TNM stages(III and IV),and showed intense expression of MMP-9 and MMP-13.CONCLUSION The present study suggests that both MMP-9 and MMP-13 play an important and independent role in OSCC progression and invasiveness.Intense expression of MMP-9 and MMP-13,irrespective of histological grade of OSCC,correlates well with TNM stage.Consequently,it is evident that MMP-9 and MMP-13 are important for the invasiveness and progression of tumors.The findings may facilitate the development of new approaches for evaluating lymph node metastases and interventional therapy techniques,hence enhancing the prognosis of patients diagnosed with OSCC.

文摘Identifying key nodes in complex networks is crucial for understanding and controlling their dynamics. Traditional centrality measures often fall short in capturing the multifaceted roles of nodes within these networks. The Page Rank algorithm, widely recognized for ranking web pages, offers a more nuanced approach by considering the importance of connected nodes. However, existing methods generally overlook the geometric properties of networks, which can provide additional insights into their structure and functionality. In this paper, we propose a novel method named Curv-Page Rank(C-PR), which integrates network curvature and Page Rank to identify influential nodes in complex networks. By leveraging the geometric insights provided by curvature alongside structural properties, C-PR offers a more comprehensive measure of a node's influence. Our approach is particularly effective in networks with community structures, where it excels at pinpointing bridge nodes critical for maintaining connectivity and facilitating information flow. We validate the effectiveness of C-PR through extensive experiments. The results demonstrate that C-PR outperforms traditional centrality-based and Page Rank methods in identifying critical nodes. Our findings offer fresh insights into the structural importance of nodes across diverse network configurations, highlighting the potential of incorporating geometric properties into network analysis.

文摘BACKGROUND The number of tumor deposits(TDs)does not play a part in the current tumor node metastasis staging.Negative lymph node(NLN)status is associated with the prognosis of colorectal cancer(CRC),but its clear role in N1c stage remains to be defined.AIM To evaluate the combination of TDs and NLNs as potential prognostic indicators in N1c CRC.METHODS We retrospectively identified 107 consecutive patients who had N1c CRC radically resected at China-Japan Friendship Hospital.The combination of TDs and NLNs was calculated by the formula NLNTD=NLN/(TD+1).Cutoff values of NLNs and NLNTD were determined using the R package“survminer”.Disease-free survival(DFS),overall survival(OS)and cancer-specific survival(CSS)were determined using the Kaplan-Meier method to assess the impact of NLNTD on prognosis.Results were compared using the log-rank test.RESULTS The median follow-up time was 63.17(45.33-81.37)months for DFS,with 33.64%(36/107)of patients experiencing recurrence during follow-up.Five-year DFS was 66.0%(57.3%-76.0%).There was no significant difference in prognosis between patients with>12 and≤12 NLNs(P=0.058)for DFS.Similar results were seen according to the number of TDs.The definition of NLNTD=NLN/(TD+1)with a cutoff value of 6 divided patients into two groups with different DFS(P=0.005).Five-year DFS for patients with NLNTD>6 was 73.5%(63.6%-85.0%),compared with 50.0%(35.7%-70.0%)for those with NLNTD≤6.These two groups had different prognosis without perineural invasion(P=0.012)or lymphovascular invasion(P=0.002)even neither(P=0.053).Similar results were seen for OS and CSS.CONCLUSION NLNTD could serve as important prognostic factor for outcomes in N1c CRC patients.These patients could be stratified for prognosis through NLNTD and the high-risk should be given more attention during treatment.
文摘Gastric cancer(GC)represents a significant global health burden due to its high morbidity and mortality.Specific behaviors of GC sub-types,distinct dissem-ination patterns,and associated risk-factors remain poorly understood.This editorial highlights several key prognostic factors,including pathological staging and vascular invasion,that impact GC.It examines a recent study’s investigation of differential metastatic lymph nodes distribution and survival in upper and lower GC sub-types,focusing on histological characterization,pathophysiology,usage of neoadjuvant chemotherapy,and additional predictive determinants.We assess the statistical robustness and clinical applicability of the findings,un-derscoring the importance of treating GC as a heterogeneous disease and em-phasizing how tailored surgical approaches informed by lymph node distribution can optimize tumor detection while minimizing unnecessary interventions.The study’s large cohort,multi-center design,and strict inclusion criteria strengthen its validity in guiding surgical planning and risk-stratification.However,inte-grating genetic and molecular data is critical for refining models and broadening applicability.Additionally,recurrence-metrics and infection-related factors,such as Helicobacter pylori and Epstein-Barr virus,absent in the original study,remain vital for directing future research.By bridging metastatic patterns with pros-pective methodologies and inclusion of diverse populations,this editorial pro-vides a framework for advancing early detection and personalized GC care.
文摘Background: Sentinel lymph node (SLN) biopsy remains a cornerstone in the management of breast cancer, as it provides an accurate staging of the disease while minimizing the morbidity associated with complete axillary lymph node dissection. Advances in SLN detection have been very important in refining surgical techniques and improving patient outcomes. The purpose of the present study is to compare the effectiveness of radiocolloids, blue dyes, and fluorescent tracers in detecting the sentinel lymph node in breast cancer. Materials and Methods: Specifically, we analyzed the detection rate, accuracy, and safety profile of the techniques to outline the most reliable and clinically available. A comprehensive review was conducted, searching key databases, including PubMed, Scopus, and Web of Science, for studies published between 2010 and 2024. The review focused on studies that compared the performance of radiocolloids, blue dyes, and fluorescent tracers in the detection of sentinel lymph nodes in breast cancer patients. A total of 54 studies were included based on specific inclusion criteria. Results: Radiocolloids showed high detection rates in studies. Blue dyes have comparable results, but a small percentage of allergic reactions has been observed. Fluorescent tracers such as indocyanine green have improved visualization and accuracy, but their use requires specialized equipment and expertise. Combining radiocolloids with blue dyes or fluorescent tracers has improved detection rates in several studies. Cost and accessibility challenges have also been pointed out, particularly in low-resource settings. Conclusions: Radiocolloids have attained the status of gold standard in the detection of SLNs in breast cancer for their reliability and accuracy. While combined use with other tracers, like blue dyes or fluorescent agents, enhances overall detection performance, making it more holistic. As expected, further innovation and effort are required to improve accessibility and optimize the technique of sentinel lymph node biopsy worldwide.
文摘Objective: Stroke is perceived as a serious illness although it is preventable, and lifestyle alterations can be made to reduce its risk. Improvement of stroke care should be achieved through awareness of public, especially through high-risk group. Henceforth, the aim of this study was to evaluate the effect of nursing intervention on improving awareness of high-risk people about stroke prevention. Methods: A quasi-experimental design was used to carry out this study, where a purposive sample of 80 adult patients at high risk for stroke were enrolled while they were attending the out-patient clinics of Zagazig University Hospitals for follow-up treatment;they were divided into two groups: case (40 patients) and control (40 patients). An interview questionnaire was used to assess patients’ knowledge regarding warning signs, risk factors, and immediate treatment;attitude;and their practice for prevention for stroke at pretest and posttest. Results: The study revealed the poor level of knowledge, bad level of preventive behavior, and negative attitude regarding stroke prevention at pre-intervention. However, after intervention, the high-risk people had fair level of knowledge with moderate practice for stroke prevention and positive attitude, with statistically significant difference between pre-post intervention and between the case and control groups. Conclusions: The study revealed that the nursing intervention seemed to change the knowledge, practice, and attitude of subjects regarding stroke prevention. This, in turn, implies that awareness of prevention of stroke and high-risk factor control could be important to reduce the burden of stroke in Egypt. Thus, further research on a larger scale is required to improve population knowledge and behavior for stroke prevention and control.
文摘Objective:To explore the perspectives of high-risk pregnant women regarding the home care program for high-risk pregnancies.Methods:This qualitative study was conducted in a university hospital and 5 comprehensive health centers in Ahvaz,Iran,from February 2023 to July 2023.The sampling method used was purposive sampling considering the maximum possible diversity,which continued until data saturation.11 in-depth and semistructured interviews were conducted with high-risk pregnant women.Data were simultaneously analysed using Graneheim and Lundman content analysis by MAXQDA version 20 software.Results:Data analysis extracted 3 themes,12 categories,and 26 subcategories.The themes and categories were“high-risk pregnancy and related issues(pursuing treatment and paying attention to the high-risk situation by pregnant women,psychological aspect of high-risk pregnancy on pregnant women and caregivers,emotional and physical aspects of high-risk pregnancy,the consequences of high-risk pregnancy on the people around them and empowerment of high-risk pregnant women)”,“support dimension(family and community support for high-risk pregnant women)”,and“framework of program(acculturalization,means and equipment,security,manpower and the necessary arrangements for the home care)”.Conclusions:High-risk pregnancy affects various aspects of the lives of high-risk pregnant women and their families.Creating the necessary conditions for providing care at home plays a vital role in supporting high-risk pregnant women and removing related obstacles to receiving prenatal care in person.It will be especially beneficial for high-risk pregnant women in low-income areas.
文摘The article by Yuan et al accessed the clinicopathologic and prognostic significance of the patterns of lymph node(LN)metastasis in upper and lower gastric cancer(GC).In this article,we will analyze both the strengths and limitations of this paper.The study’s methodology seems appropriate and proper statistical analyses were applied to identify significant variables.The authors applied the Cox regression model to identify independent risk factors and Kaplan-Meier survival curves to assess prognosis.The researchers found notable differences in cli-nicopathologic variables between patients with upper and lower GC.Addi-tionally,they identified specific LN stations more prone to metastasis in different Siewert classifications of GC.Despite the study’s detailed analysis,it would have been beneficial to explore whether there were survival differences among upper GC patients based on the Siewert classification.Furthermore,the study should have addressed potential confounding factors that might have influenced the results.A more comprehensive analysis could have been achieved by comparing survival outcomes based on LN metastasis patterns.Overall,this article is relevant and provides valuable insights into the significance of LN metastasis patterns in upper GC patients.

文摘BACKGROUND Lymph node status is a critical prognostic factor in gastric cancer(GC),but stage migration may occur in pathological lymph nodes(pN)staging.To address this,alternative staging systems such as the positive lymph node ratio(LNR)and log odds of positive lymph nodes(LODDS)were introduced.AIM To assess the prognostic accuracy and stratification efficacy of three nodal staging systems in GC.METHODS A systematic review identified 12 studies,from which hazard ratios(HRs)for overall survival(OS)were summarized.Sensitivity analyses,subgroup analyses,publication bias assessments,and quality evaluations were conducted.To enhance comparability,data from studies with identical cutoff values for pN,LNR,and LODDS were pooled.Homogeneous stratification was then applied to generate Kaplan-Meier(KM)survival curves,assessing the stratification efficacy of three staging systems.RESULTS The HRs and 95%confidence intervals for pN,LNR,and LODDS were 2.16(1.72-2.73),2.05(1.65-2.55),and 3.15(2.15-4.37),respectively,confirming all three as independent prognostic risk factors for OS.Comparative analysis of HRs demonstrated that LODDS had superior prognostic predictive power over LNR and pN.KM curves for pN(N0,N1,N2,N3a,N3b),LNR(0.1/0.2/0.5),and LODDS(-1.5/-1.0/-0.5/0)revealed significant differences(P<0.001)among all prognostic stratifications.Mean differences and standard deviations in 60-month relative survival were 27.93%±0.29%,41.70%±0.30%,and 26.60%±0.28%for pN,LNR,and LODDS,respectively.CONCLUSION All three staging systems are independent prognostic factors for OS.LODDS demonstrated the highest specificity,making it especially useful for predicting outcomes,while pN was the most effective in homogeneous stratification,offering better patient differentiation.These findings highlight the complementary roles of LODDS and pN in enhancing prognostic accuracy and stratification.
文摘Objective Almost 15%of prostate cancer(PCa)patients were found to have lymph node metastases(LNMs),which are associated with higher risk of biochemical recurrence.Using indocyanine green(ICG)for the sentinel node biopsy(SNB)before surgery was proposed to detect LNMs in PCa patients.However,its diagnostic performance still remains controversial.This study aimed to investigate the diagnostic performance of ICG for the SNB in PCa.Methods This systematic review and meta-analysis has been reported in line with the Preferred Reporting Items for Systematic reviews and Meta-Analyses guidelines.The protocol has been registered in the International Prospective Register of Systematic Reviews database,and the register number is CRD42023421911.Four bibliographic databases were searched,i.e.,PubMed,EMBASE,Cochrane Library,and Web of Science,to retrieve articles studying the diagnostic performance of ICG for the SNB in PCa from the inception to Sep 9,2023.We calculated the pooled sensitivity,specificity,likelihood ratios,diagnostic odds ratios and their 95%confidence intervals(CIs).Subgroup analyses and meta-regression analyses were also conducted.Results A total of 17 articles from databases are enrolled in this study.Using lymph node-based data,our results showed that the pooled sensitivity and specificity of applying ICG alone in PCa were 71%(95%CI 52%–85%)and 68%(95%CI 64%–72%),respectively.The pooled sensitivity and specificity of applying ICG-technetium-99m-nanocolloid in PCa were 49%(95%CI 39%–59%)and 69%(95%CI 67%–71%),respectively.
文摘Gastric cancer(GC)remains a leading cause of cancer mortality.While the extent of nodal involvement is a well-known prognostic factor,the specific entity of swollen lymph node metastasis(SLNM),bulky nodal tumor deposits detectable radiologically or pathologically,has received little attention in staging.Recent data from a study by Cui et al demonstrated that SLNM is an independent predictor of very poor survival in GC.Through robust data and rigorous propensitymatched analyses,SLNM emerged not merely as an anatomical finding but as an independent predictor of poor prognosis,even among patients undergoing curative resection.As precision oncology advances,the findings by Cui et al urge a fundamental rethinking of how SLNM is incorporated into clinical decisionmaking for GC management.In this editorial,we critically examine the prognostic significance of SLNM,challenge its omission from traditional staging frameworks,and advocate for its formal integration into preoperative risk stratification and treatment planning.Recognizing SLNM at diagnosis could unlock intensified neoadjuvant therapy strategies and optimize outcomes for a historically high-risk patient subgroup.
