An analysis of precancerous stomach lesions revealed that chronic atrophic gastritis (CAG) was a universal common among people aged 35-64 (96-98%). For 52% and 20% of the residents in this age group had Intestinal metaplasia (IM) or dysplssia (DYS). These more advanced lesions were more pronounced in the antrum for both males and females. Age-specific prevalence rates in different anatomic locations sshowed that CAG, developed in the antrum, particularly along the lesser curvature earter than other sites and spread to fundus. IM and DYS accrued under the background of CAG with a leading time in the antrum than the other part of the stomach. Although CAG, IM and DYS prevalence rates were higher in the antrum than In the fundus, the prevalence rates showed a similar smoothly slope, a result of accumulated somatic geneticdamage, suggesting a similar biological response to the stimulation of initiator of carcinogenesis, promoter leading to progression to SC.展开更多

Cameroon has rolled out immunization against HPV 16 and 18, but studies show a higher prevalence of non-16/18 HR-HPV types. Objectives: Determine the prevalence of precancerous lesions, in women with HR-HPV infection and evaluate association of digital cervicography (DC) VIA/VILI positivity with HPV serotype, as a measure of their contribution to precancer and cancer incidence. Methodology: The study was cross-sectional, descriptive, and analytic. It took place at the Etoug-Ebe and Ekoudoum Baptist Hospitals in Yaoundé, during the period April-September 2022. We reviewed the records of women screened for cervical cancer between February 2020 and December 2021 and evaluated the prevalence of lesions on digital cervicography (DC) with VIA/VILI for women positive for HR-HPV serotypes. The data were analyzed using SPSS version 20.0 for Windows. P values Results: We identified 315 cases with a positive HR-HPV deoxyribonucleic acid (DNA) test, 224 (71.1%) had a DC VIA/VILI triage test done. Of these, 30 (13.4%) women had a positive DC VIA/VILI, with five women (2.2%) having lesions suggestive of cancer. Out of 11 cases positive for HPV 16 alone, 05 (45.5%) had a positive DC VIA/VILI test. Of the 14 cases positive for HPV 18 alone, 03 (21.4%) had a positive VIA/VILI, meanwhile only 19 (10.7%) of the 177 cases positive for non-16/18 HPV had a positive VIA/VILI test. Conclusion: A high proportion of women (13.4%) with HR HPV had a positive DC VIA/VILI, with a significant proportion (2.2%) having lesions suggestive of invasive cervical cancer HR-HPV serotype was associated with DC VIA/VILI positivity;HPV 16 had the strongest association (45.5%), followed by HPV 18 (21.4%), and non-16/18 HR-HPV (10.7%), suggesting a decreasing order of oncogenicity.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

However, the predictive capability of post-angioplasty QFR for long-term clinical events in patients with de novo lesions who receive DCB treatment remains uncertain. The aim of this study was to explore the potential significance of post-angioplasty QFR measurements in predicting clinical outcomes in patients underwent DCB treatment for de novo lesions.Methods Patients who underwent DCB-only intervention for de novo lesions were enrolled. QFR was conducted after DCB treatment. The patients were then categorized based on post-angioplasty QFR. The primary endpoint was major adverse cardiac events(MACE), encompassing all-cause death, cardiovascular death, nonfatal myocardial infarction, stroke, and target vessel revascularization.Results A total of 553 patients with 561 lesions were included. The median follow-up period was 505 days, during which 66(11.8%) MACEs occurred. Based on post-procedural QFR grouping, there were 259 cases in the high QFR group(QFR > 0.93) and302 cases in the low QFR group(QFR ≤ 0.93). Kaplan-Meier analysis revealed a significantly higher cumulative incidence of MACE in the low QFR group(log-rank P = 0.004). The multivariate Cox proportional hazards model demonstrated a significant inverse correlation between QFR and the occurrence of MACEs(HR = 0.522, 95%CI: 0.289-0.942, P = 0.031). Landmark analysis indicated that high QFR had a significant reducing effect on the cumulative incidence of MACEs within 1 year(log-rank P = 0.016)and 1-5 years(log-rank P = 0.026).Conclusions In patients who underwent DCB-only treatment for de novo lesions, higher post-procedural QFR values(> 0.93)were identified as an independent protective factor against adverse prognosis.展开更多

文摘Background:The development of gastric cancer(GC)encompasses precancerous conditions like chronic atrophic gastritis(CAG)and premalignant lesions of gastric cancer(PLGC).In these situations,abnormal Notch signaling results in mucosal impairment and the initiation of cancer.Banxia Xiexin Decoction(BXD),a well-known formula in traditional Chinese medicine(TCM),shows promise in treating gastric disorders,but its mechanisms in gastric restoration remain unclear.Methods:Using MNNG-induced CAG and PLGC rat models,BXD was administered for 12 weeks.Gastric mucosal pathology was assessed via hematoxylin-eosin staining.Proliferation(Ki-67)and angiogenesis(VEGFA)markers were evaluated by immunohistochemistry.Network pharmacology identified BXD’s targets and pathways.Notch pathway components(Notch1,Jagged1,Dll4,Hes1)were analyzed via qPCR,Western blot,and immunohistochemistry.Results:BXD significantly ameliorated mucosal atrophy,glandular structural disorder,and dysplasia in CAG and PLGC rats.Network pharmacology revealed 323 overlapping targets between BXD and PLGC,with Notch signaling as a central pathway.BXD downregulated Notch1,Jagged1,Dll4,and Hes1 expression at transcriptional and protein levels,suppressed Ki-67(proliferation)and VEGFA(angiogenesis)overexpression,and restored gastric mucosal integrity.Conclusion:BXD inhibits Notch signaling,reduces aberrant proliferation and angiogenesis,and interrupts Correa’s gastric carcinogenesis cascade.This study provides mechanistic evidence supporting BXD as a TCM-based intervention for gastric precancerous lesions.

文摘Recent evidence suggests that ferroptosis plays a crucial role in the occurrence and development of white matter lesions.However,the mechanisms and regulatory pathways involved in ferroptosis within white matter lesions remain unclear.Long non-coding RNAs(lnc RNAs)have been shown to influence the occurrence and development of these lesions.We previously identified lnc_011797 as a biomarker of white matter lesions by high-throughput sequencing.To investigate the mechanism by which lnc_011797 regulates white matter lesions,we established subjected human umbilical vein endothelial cells to oxygenglucose deprivation to simulate conditions associated with white matter lesions.The cells were transfected with lnc_011797 overexpression or knockdown lentiviruses.Our findings indicate that lnc_011797 promoted ferroptosis in these cells,leading to the formation of white matter lesions.Furthermore,lnc_011797 functioned as a competitive endogenous RNA(ce RNA)for mi R-193b-3p,thereby regulating the expression of WNK1 and its downstream ferroptosis-related proteins.To validate the role of lnc_011797 in vivo,we established a mouse model of white matter lesions through bilateral common carotid artery stenosis.The results from this model confirmed that lnc_011797 regulates ferroptosis via WNK1 and promotes the development of white matter lesions.These findings clarify the mechanism by which lnc RNAs regulate white matter lesions,providing a new target for the diagnosis and treatment of white matter lesions.
文摘A population-based screening for stomach cancer (SC) and its precancerous lesions was conducted in Linqu County, Shandong, China, one of the highest SC rates found in China and the world. An analysis of precancerous stomach lesions revealed that chronic atrophic gastritis (CAG) was a universal common among people aged 35-64 (96-98%). For 52% and 20% of the residents in this age group had Intestinal metaplasia (IM) or dysplssia (DYS). These more advanced lesions were more pronounced in the antrum for both males and females. Age-specific prevalence rates in different anatomic locations sshowed that CAG, developed in the antrum, particularly along the lesser curvature earter than other sites and spread to fundus. IM and DYS accrued under the background of CAG with a leading time in the antrum than the other part of the stomach. Although CAG, IM and DYS prevalence rates were higher in the antrum than In the fundus, the prevalence rates showed a similar smoothly slope, a result of accumulated somatic geneticdamage, suggesting a similar biological response to the stimulation of initiator of carcinogenesis, promoter leading to progression to SC.
文摘Background: Since 2021, high-risk Human Papilloma Virus (HR-HPV) testing has been the recommended screening test for cervical cancer for all settings;either used alone in a “test and treat” strategy, or with a triage test, with or without biopsy, before treatment. Cameroon has rolled out immunization against HPV 16 and 18, but studies show a higher prevalence of non-16/18 HR-HPV types. Objectives: Determine the prevalence of precancerous lesions, in women with HR-HPV infection and evaluate association of digital cervicography (DC) VIA/VILI positivity with HPV serotype, as a measure of their contribution to precancer and cancer incidence. Methodology: The study was cross-sectional, descriptive, and analytic. It took place at the Etoug-Ebe and Ekoudoum Baptist Hospitals in Yaoundé, during the period April-September 2022. We reviewed the records of women screened for cervical cancer between February 2020 and December 2021 and evaluated the prevalence of lesions on digital cervicography (DC) with VIA/VILI for women positive for HR-HPV serotypes. The data were analyzed using SPSS version 20.0 for Windows. P values Results: We identified 315 cases with a positive HR-HPV deoxyribonucleic acid (DNA) test, 224 (71.1%) had a DC VIA/VILI triage test done. Of these, 30 (13.4%) women had a positive DC VIA/VILI, with five women (2.2%) having lesions suggestive of cancer. Out of 11 cases positive for HPV 16 alone, 05 (45.5%) had a positive DC VIA/VILI test. Of the 14 cases positive for HPV 18 alone, 03 (21.4%) had a positive VIA/VILI, meanwhile only 19 (10.7%) of the 177 cases positive for non-16/18 HPV had a positive VIA/VILI test. Conclusion: A high proportion of women (13.4%) with HR HPV had a positive DC VIA/VILI, with a significant proportion (2.2%) having lesions suggestive of invasive cervical cancer HR-HPV serotype was associated with DC VIA/VILI positivity;HPV 16 had the strongest association (45.5%), followed by HPV 18 (21.4%), and non-16/18 HR-HPV (10.7%), suggesting a decreasing order of oncogenicity.

文摘BACKGROUND Effective health management for high-risk stroke populations is essential.The hospital-community-home(HCH)collaborative health management(CHM)model leverages resources from hospitals,communities,and families.By integrating patient information across these three domains,it facilitates the delivery of tailored guidance,health risk assessments,and three-in-one health education.AIM To explore the effects of the HCH-CHM model on stroke risk reduction in highrisk populations.METHODS In total,110 high-risk stroke patients screened in the community from January 2019 to January 2023 were enrolled,with 52 patients in the control group receiving routine health education and 58 in the observation group receiving HCH-CHM model interventions based on routine health education.Stroke awareness scores,health behavior levels,medication adherence,blood pressure,serum biochemical markers(systolic/diastolic blood pressure,total cholesterol,and triglyceride),and psychological measures(self-rating anxiety/depression scale)were evaluated and compared between groups.RESULTS The observation group showed statistically significant improvements in stroke awareness scores and health behavior levels compared to the control group(P<0.05),with notable enhancements in lifestyle and dietary habits(P<0.05)and reductions in postintervention systolic blood pressure,diastolic blood pressure,total cholesterol,triglyceride,self-rating anxiety scale,and self-rating depression scale scores(P<0.05).CONCLUSION The HCH-CHM model had a significant positive effect on high-risk stroke populations,effectively increasing disease awareness,improving health behavior and medication adherence,and appropriately ameliorating blood pressure,serum biochemical marker levels,and negative psychological symptoms.
文摘This letter critically evaluates Jiang et al's article on the differentiation of benign and malignant liver lesions using Emax and platelet count.Despite notable findings,significant methodological and interpretative limitations are identified.The study lacks detailed assay conditions for Emax measurement,employs inadequate statistical methods without robust multivariate analysis,and does not provide clinically relevant threshold values.The nomogram's reliance on Emax as a major diagnostic contributor is questionable due to attenuation in hepatocellular carcinoma patients with cirrhosis.Moreover,the study's limitations,such as selection bias and confounding factors,are not adequately addressed.Future research should adopt more rigorous methodologies,including prospective studies with larger cohorts and standardized protocols for biomarker measurement,to enhance validity and clinical applicability.

文摘Objective:In recent years,the incidence and detection rate of pancreatic cystic lesions(PCLs)have increased significantly.Endoscopic ultrasound(EUS)plays an indispensable role in the diagnosis and differential diagnosis of PCLs.However,evidence comparing the diagnostic performance of EUS-guided fine-needle aspiration(EUS-FNA)and fine-needle biopsy(FNB)remains limited.This study aims to compare the diagnostic yield,adequacy of tissue acquisition,and safety between EUS-FNA and EUS-FNB in evaluating PCLs to inform clinical practice.Methods:A retrospective review was conducted on patients with PCLs who underwent either EUS-FNA or EUS-FNB between January 2014 and August 2021.The diagnostic yield,tissue acquisition adequacy,and incidence of adverse events were compared between the 2 groups.Results:A total of 90 patients with PCLs were included(52 in the FNA group and 38 in the FNB group).The diagnostic yield was similar between the FNA and FNB groups(94.2%vs 94.7%,P>0.05).The adequacy of tissue acquisition was 71.2%in the FNA group and 81.6%in the FNB group(P>0.05).No statistically significant difference was observed in the incidence of adverse events between the 2 groups(P>0.05).Conclusion:Both EUS-FNA and EUS-FNB demonstrate equally high diagnostic yields and tissue adequacy in PCLs,with excellent safety profiles.Both methods are safe and effective diagnostic tools for evaluating PCLs.
文摘Calvarial lesions are usually incidental and asymptomatic,rarely detected.However,these lesions can also present with pain,a palpable mass or a bone defect.Clinical information such as the patient’s age and medical history are helpful in making the correct diagnosis.Calvarial lesions may occur due to congenital and anatomical variants,traumatic and iatrogenic,idiopathic,infectious and inflammatory,metabolic,benign and malignant neoplastic causes.Calvarial lesions may be solitary,multiple or diffuse,and may be lytic,sclerotic or mixed.Although most calvarial lesions are benign,radiologic imaging features can help to determine whether the lesion is benign or malignant.Methods that can guide treatment and are currently in use include plain radiography,ultrasonography,computed tomography,magnetic resonance imaging,angiographic studies,and nuclear scintigraphy studies such as 18F-fluorodeoxyglucose positron emission tomography and whole-body bone scintigraphy.Defects,lysis and sclerosis in the bone structure are assessed by plain radiography and computed tomography,and the soft tissue components of the lesions and their relationship to the surrounding soft tissue are assessed by magnetic resonance imaging.This article reviews the imaging findings of benign and malignant calvarial lesions and normal variants that may be confused with systemic diseases and pathologies affecting the calvarium.
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Background:Human papillomavirus(HPV)infection is a major risk factor of cervical cancer.This study assessed the prevalence and distribution of HPV genotypes in women with cervical or vaginal lesions in Jiangsu Province,China.Methods:A total of 2120 healthy women aged 18–45 years were screened between 2012 and 2013 and 6171 healthy women aged18–45 years were screened between 2020 and 2021 in Jiangsu Province.Cervical specimens collected from each woman were first tested using the HPV DNA enzyme immunoassay method,and positive samples were further tested using the reverse hybridization line probe assay.Differences in HPV prevalence and genotype distribution were compared between women with cervical and vaginal lesions identified during 2 rounds of cross-sectional screening.To account for differences in age composition between the 2 studies,the standardized prevalence of HPV positivity was calculated using the sum of the total number of women diagnosed with cervical or vaginal lesions during both periods as the standard group.Results:Overall,40 women(1.89%)were diagnosed with cervical or vaginal lesions through biopsy during 2012–2013,and 110(1.78%)were diagnosed during 2020–2021.Among women with lesions,the standardized HPV positivity rates were 98.41%in 2012–2013 and99.24%in 2020–2021.Most cases were caused by high-risk HPV,which accounted for 87.18%of the total infections during 2012–2013and 89.91%of those in 2020–2021,with standardized positivity rates of 86.44%and 88.75%,respectively.The standardized positivity rates for single infections were 62.35%in 2012–2013 and 74.95%in 2020–2021.The top 5 high-risk HPV genotypes were HPV type 16(HPV16;29.01%),52(20.63%),18(14.28%),58(13.71%),and 33(12.12%)in 2012–2013,and HPV16(36.95%),58(22.18%),52(13.25%),31(7.63%),and 51(6.81%)in 2020–2021.The standardized positivity rate for HPV18 decreased from 14.28%in2012–2013 to 1.15%in 2020–2021.Among women with cervical or vaginal lesions,the highest proportion was observed in the 36-to 45-year group during 2012–2013,reaching 52.50%,and in the 26-to 35-year group during 2020–2021,peaking at 59.10%.Conclusions:In Jiangsu Province,no significant changes in HPV prevalence among women with cervical or vaginal lesions were observed during 2012–2013 and 2020–2021;however,the distribution of HPV genotypes had changed.
文摘The introduction of drug-eluting stents has significantly reduced the incidence of in-stent restenosis.Despite this,recurrent cardiovascular events related to untreated nontarget lesions(NTLs)are becoming more common and accounting for more than 50%of all recurrent cardiovascular events.In patients with dia-betes,factors such as prolonged disease duration,poor glycemic control,insulin use,and inadequate lipid management may exacerbate the progression of NTLs and adverse cardiovascular events.Additionally,glycemic fluctuations have been linked to an increased risk of future cardiovascular events in patients with early glucose metabolism abnormalities and acute hyperglycemia.In this review,we explored the clinical and plaque characteristics of patients with diabetes and early glucose metabolism disorders,the percutaneous coronary intervention strategies for NTLs,and their prognostic implications.Furthermore,we investigated the mechanistic links between adverse cardiovascular outcomes and elevated inflammation,oxidative stress,hypercoagulability,and endothelial dysfunction.

文摘BACKGROUND The incidence and mortality of colorectal cancer continue to rise.For early-stage colorectal cancer,endoscopic resection has become a preferred or important treatment option due to its significant advantages in operative time,extent of trauma,and medical costs.However,increasing lesion diameter significantly elevates the technical difficulty of endoscopic resection.Currently,robust evidence-based evidence regarding the upper size limit for safely and effectively resecting lesions endoscopically remains lacking.AIM To evaluate the efficacy and safety of endoscopic resection for colorectal lesions≥30 mm in diameter.METHODS This retrospective study reviewed data from 102 patients who underwent endoscopic resection for colorectal lesions measuring≥30 mm in diameter at General Hospital of Northern Theater Command between January 2023 and July 2024.RESULTS Among 102 patients who underwent endoscopic resection,99 received endoscopic submucosal dissection and 3 underwent endoscopic full-thickness resection.Four patients(3.9%)required conversion to surgical radical resection postoperatively.All patients exhibited favorable wound healing at the resection sites,and no long-term complications were observed during the 3-month postoperative colonoscopy follow-up.The primary perioperative complication was post-endoscopic submucosal dissection electrocoagulation syndrome(PEECS)(24/102,23.5%).Multivariate analysis identified lesion location in the transverse colon as an independent risk factor for PEECS occurrence(odds ratio=6.734,95%confidence interval:1.623-27.945,P=0.009).CONCLUSION Large colorectal lesion diameter does not constitute an absolute contraindication to endoscopic resection.Experienced endoscopic centers can achieve complete resection with a favorable efficacy and safety profile.Notably,lesion location in the transverse colon is identified as an independent risk factor for PEECS.
文摘Background:Loneliness is a common experience for pregnant women and correlates with perinatal depression and negative pregnancy outcomes.Women experiencing a high-risk pregnancy are at greater risk for loneliness because of uncertainty with disease and the medicalization of pregnancy.International studies have identified an association between perceived stress and loneliness in pregnant women.The aim of this study is to explore factors related to loneliness among women of high-risk pregnancy,and to examine the associated relationship of loneliness and perceived stress.Methods:Using convenience sampling,109 women with high-risk pregnancies were enrolled.Data collection involved questionnaires on general demographic characteristics,the 6-item Loneliness Scale(ULS-6),and the Chinese version of the Perceived Stress Scale(CPSS-14).Data analysis was performed using SPSS 28.0 statistical software.Results:The mean loneliness score was 9.95±2.99,and the mean perceived stress score was 22.84±5.80.Women with high-risk pregnancies exhibited statistically significant differences in loneliness scores compared to the control group across among age,marital status,educational attainment,per capita monthly household income,spousal relationship,in-law relationship,and parental relationship(P<0.05).Correlation analysis revealed a positive correlation between loneliness and perceived stress(r=0.456,P<0.01).Multivariate regression analysis indicated that per capita monthly household income,marital relationship,in-law relationship,and perceived stress were the primary factors influencing loneliness among women with high-risk pregnancies(P<0.05).Conclusion:The results highlight the need for specific interventions addressing loneliness among women with high-risk pregnancies.Such interventions should focus on improving spousal and in-law relationships,reducing perceived stress,and implementing support measures,such as financial counseling or assistance programs,for those with lower per capita household income.This study establishes a foundation for the creation of integrated support systems that bring together families and healthcare providers to strengthen maternal mental health.

文摘Background Quantitative flow ratio(QFR) holds significant value in guiding drug-coated balloon(DCB) treatment and enhancing outcomes. However, the predictive capability of post-angioplasty QFR for long-term clinical events in patients with de novo lesions who receive DCB treatment remains uncertain. The aim of this study was to explore the potential significance of post-angioplasty QFR measurements in predicting clinical outcomes in patients underwent DCB treatment for de novo lesions.Methods Patients who underwent DCB-only intervention for de novo lesions were enrolled. QFR was conducted after DCB treatment. The patients were then categorized based on post-angioplasty QFR. The primary endpoint was major adverse cardiac events(MACE), encompassing all-cause death, cardiovascular death, nonfatal myocardial infarction, stroke, and target vessel revascularization.Results A total of 553 patients with 561 lesions were included. The median follow-up period was 505 days, during which 66(11.8%) MACEs occurred. Based on post-procedural QFR grouping, there were 259 cases in the high QFR group(QFR > 0.93) and302 cases in the low QFR group(QFR ≤ 0.93). Kaplan-Meier analysis revealed a significantly higher cumulative incidence of MACE in the low QFR group(log-rank P = 0.004). The multivariate Cox proportional hazards model demonstrated a significant inverse correlation between QFR and the occurrence of MACEs(HR = 0.522, 95%CI: 0.289-0.942, P = 0.031). Landmark analysis indicated that high QFR had a significant reducing effect on the cumulative incidence of MACEs within 1 year(log-rank P = 0.016)and 1-5 years(log-rank P = 0.026).Conclusions In patients who underwent DCB-only treatment for de novo lesions, higher post-procedural QFR values(> 0.93)were identified as an independent protective factor against adverse prognosis.
