Real-world evidence on the efficacy and safety of vonoprazanamoxicillin dual therapy for Helicobacter pylori treatment in elderly patients

BACKGROUND A dual therapy regimen containing amoxicillin is a common treatment option for the eradication of Helicobacter pylori(H.pylori).While substantial research supports the efficacy and safety of vonoprazan and amoxicillin(VA)dual therapy in the general population,there is still a lack of studies specifically focusing on its safety in elderly patients.AIM To evaluate efficacy and safety of VA dual therapy as first-line or rescue treatment for H.pylori in elderly patients.METHODS As a real-world retrospective study,data were collected from elderly patients aged 60 years and above who accepted VA dual therapy(vonoprazan 20 mg twice daily+amoxicillin 1000 mg thrice daily for 14 days)for H.pylori eradication in the Department of Gastroenterology at Peking University First Hospital between June 2020 and January 2024.H.pylori status was evaluated by^(13)C-urease breath test 6 weeks after treatment.All adverse events(AEs)during treatment were recorded.RESULTS In total,401 cases were screened.Twenty-one cases were excluded due to loss to follow-up,lack of re-examination,or unwillingness to take medication.The total of 380 included cases comprised 250 who received VA dual therapy as first-line treatment and 130 who received VA dual therapy as rescue treatment.H.pylori was successfully eradicated in 239 cases(95.6%)in the first-line treatment group and 116 cases(89.2%)in the rescue treatment group.The overall incidence of AEs was 9.5%for both groups.Specifically,9.2%of patients experienced an AE in the first-line treatment group and 10.0%in the rescue treatment group.Five patients discontinued treatment due to AE,with a discontinuation rate of 1.3%.No serious AE occurred.CONCLUSION The VA dual therapy regimen as a first-line treatment and a rescue therapy was effective and safe for elderly patients aged 60 and older.

Insights into anesthesia administration for elderly individuals undergoing painless gastroenteroscopy: A bibliometric study

BACKGROUND Administering anesthesia to elderly patients undergoing gastroenteroscopy necessitates careful attention due to age-related physiological changes and an increased risk of complications.AIM To analyze the research trends in anesthesia management for elderly patients undergoing gastroenteroscopy.METHODS We performed a literature search using the Web of Science database to identify articles published between 2004 and 2023.Bibliometric and visual analyses were conducted using CiteSpace,R,and VOSviewer to explore the current research landscape of anesthesia administration in painless gastroenteroscopy for elderly patients and to identify future research directions by examining trends and emerging hotspots in this domain.RESULTS A total of 800 articles were examined,revealing a rising trend in annual pub-lication counts.The United States led with 181 articles,followed by China with 112,collectively contributing over 35%of the studies among the top ten countries.The majority of publications appeared in the United States journals,with the top three being Gastrointestinal Endoscopy[impact factor(IF)=7.7,H-index=26],Digestive Diseases and Sciences(IF=3.1),and Endoscopy(IF=9.3).Six primary research clusters were identified:Obstructive sleep apnea and airway manage-ment,surveillance and risk factors,colorectal cancer examination and treatment,sedation and safety of propofol and midazolam,patient satisfaction,and mortality and complications.These findings underscore the pivotal focus areas in anesthesia for elderly patients undergoing gastroenteroscopy.CONCLUSION A comprehensive understanding of current research trends and hotspots will aid anesthesiologists in developing more evidence-based practices,thereby improving the safety and outcomes for elderly patients undergoing gastroenteroscopy.

Glomerular filtration rate and comorbidity factors in elderly hospitalizations

BACKGROUND With an increase in the elderly population,the frequency of hospitalizations in recent years has also risen at a rapid pace.This,in turn,has resulted in poor outcomes and costly treatments.Hospitalization rates increase in elderly patients due to a decline in glomerular filtration rate(GFR).AIM To investigate the connection between GFR and comorbidity and reasons for hospitalization in elderly patients.METHODS We analyzed patients aged 75 years and over who were admitted to the internal medicine clinic of a tertiary hospital in Eskisehir.At admission,we calculated GFR values using the Modification of Diet in Renal Disease study formula and classified them into six categories:G1,G2,G3a,G3b,G4,and G5.We analyzed associations with hospitalization diagnoses and comorbidity factors.RESULTS The average age of the patients was 80.8 years(±4.5 years).GFR was 57.287±29.5 mL/kg/1.73 m2 in women and 61.3±31.5 mL/kg/1.73 m2 in men(P=0.106).Most patients were admitted to the hospital at G2 stage(32.8%).The main reasons for hospitalization were anemia(34.4%and 28.6%)and malnutrition(20.9%and 20.8%)in women and men,respectively(P=0.078).The most frequent comor-bidity leading to hospitalization was arterial hypertension(n=168,28%),fo-llowed by diabetes(n=166,27.7%)(P=0.001).CONCLUSION When evaluating geriatric patients,low GFR alone does not provide sufficient information.Patients’comorbid factors should also be taken into account.There is no association between low GFR during hospitalization and hospitalization-Hamarat H.Aging and GFR related diagnoses.Knowing the GFR value before hospitalization will be more informative in such studies.

Bivalirudin for anticoagulation in elderly acute coronary syndrome:Effects on myocardial microcirculation and adverse events

The management of acute coronary syndrome(ACS)in older patients remains challenging because standard anticoagulants often fail to yield optimal outcomes.Bivalirudin,a direct inhibitor of thrombin,serves as an alternative to traditional therapies.This drug is particularly effective in enhancing myocardial microcircu-lation and reducing adverse events after clinical interventions.The present article explores the findings of a recent study that highlighted the clinical benefits of bivalirudin by investigating its effects on myocardial microcirculation and adverse cardiac events after percutaneous coronary intervention in older patients with ACS.Compared with unfractionated heparin,bivalirudin markedly reduced the emergency response time and improved cardiac function indicators.It further mitigated the risks of cardiovascular events and recurrent myocardial infarctions.These findings suggest that bivalirudin can enhance myocardial perfusion and reduce bleeding complications,thus serving as a safe,effective anticoagulation agent for older patients with ACS.Nonetheless,further large-scale,high-quality trials are needed to establish optimal usage guidelines and assess long-term outcomes.Integrating bivalirudin into ACS treatment protocols for older patients may help optimize patient care,balancing efficacy and safety.Continual research and consensus building are necessary for the widespread clinical application of bivalirudin and the improvement of ACS outcomes in older patients.

Comparison of biomechanical indices measured by ocular response analyzer between children and elderly:a systematic review

Biomechanical study of the visual system by ocular response analyzer investigates the inter-structural biological relationships,mechanics,and function of the visual system.This review aimed to investigate the changes in corneal biomechanical parameters with age and sex.The articles published in PubMed between 2000 and 2021 were investigated and critiqued,and valid scientific evidence was collected,reviewed and concluded according to the inclusion and exclusion criteria.Most studies showed that corneal biomechanical changes occur infrequently in children up to the age of 20y,and with increasing age and wider age range,there was a significant decrease in corneal biomechanical indices,especially corneal hysteresis.In children and adults,most studies have shown that these biomechanical indicators,especially corneal resistance factor,were higher in females.Although hormonal changes may contribute to this finding,the role of axial length and other biometric indicators should not be ignored.The axial length,the intraocular pressure,and the corneal thickness are other factors associated with biomechanical parameters that should be taken into account in clinical diagnosis and management especially for patients undergoing refractive surgery as well as keratoconus patients.

Isletβ-cell function preservation by different anti-diabetic treatments in Chinese elderly patients with type 2 diabetes mellitus

BACKGROUND The preservation of isletβ-cell function in elderly patients with type 2 diabetes mellitus(T2DM)is a top priority for diabetic control.AIM To assess the preservation of isletβ-cell function among elderly Chinese patients with T2DM after different anti-diabetic treatments.METHODS In this longitudinal observational study,elderly patients with T2DM treated with insulin,oral antidiabetic drugs or a combination of both were enrolled to disclose their isletβ-cell function between baseline and follow-up.Isletβ-cell function was determined by the plasma Homeostasis Model forβ-cell function(HOMA-β),Cpeptide and area under the curve(AUC)based on oral glucose tolerance test.Changes inβ-cell function(decrement or increment from baseline)between different therapy groups were the outcomes.RESULTS In total,745 elderly patients(≥60 years)with T2DM[insulin monotherapy,n=105;oral anti-diabetic drugs(OAD)monotherapy,n=321;insulin plus OAD,n=319]had their baseline and follow-upβ-cell function assessed during a median observation period of 4.5 years(range,3.0-7.2 years).Overall,isletβ-cell function(HOMA-β,fasting Cpeptide,fasting insulin,AUCc-pep,AUCins,AUCc-pep/AUCglu,AUCins/AUCglu)consistently deteriorated over time regardless of the three different antidiabetic treatments.No statistical differences in decrement were observed among the three groups regarding the isletβ-cell function indices.All three groups showed an increased ratio of delayed insulin secretion response after 4.5 years of observation.CONCLUSION In Chinese elderly patients with T2DM,isletβ-cell function progressively declines regardless of insulin supplement or insulin plus OAD treatments.

Conjunctival microbiota variations in a subset of middleaged and elderly individuals from Beijing,China

AIM:To isolate and identify the conjunctival microbiota of cataract patients and analyze the associated influencing factors.METHODS:This study recruited 216 participants(216 eyes)from April 2022 to July 2022.Under the condition of no antibiotic use prior to cataract surgery,sterile swabs were used to collect samples from the lower conjunctival sac.Bacterial cultures were then conducted,followed by species identification through 16S rDNA gene sequencing.Clinical factors associated with positive or negative bacterial isolation rates were analyzed,including age,gender,meibomian gland dysfunction(MGD),history of hypertension,history of diabetes,history of cancer,history of infectious diseases and the habit of wearing masks.RESULTS:Among the 216 eyes,78 eyes yielded isolates,with an isolation rate of 36.11%,detecting a total of 122 strains.Gram-positive rods accounted for 49.18%(60 strains),gram-positive cocci accounted for 45.08%(55 strains),gram-negative bacteria accounted for 4.92%(6 strains),and fungi accounted for 0.82%(1 strain).This study found that the most abundant genera in the conjunctival sac were Corynebacterium(42.62%),Staphylococcus(31.15%),Micrococcus(9.84%),Acinetobacter(4.10%),and Bacillus(3.28%).Furthermore,age(P=0.006),gender(P=0.039),diabetes(P=0.003),history of infectious diseases(P=0.02),and duration of mask replacement(P<0.001)were important factors influencing the positive bacterial culture of the conjunctival microbiota.Although hypertensive patients exhibited a higher isolation rate of conjunctival bacteria,it did not reach statistical significance,and the history of cancer did not affect the isolation rate of the conjunctival microbial community in cataract patients before surgery.CONCLUSION:Potential changes are observed in the conjunctival microbiota among a sample of middleaged and elderly individuals from Beijing,China.Notably,an increased isolation rate of Corynebacterium and Micrococcus is detected,suggesting a possible change in the microbial balance that requires further investigation and attention from the ophthalmological community.Advanced age,female gender,MGD,diabetes,a recent history of infectious diseases,and inadequate mask-wearing habits are potentially significant factors associated with the conjunctival microbiota.These factors should be considered in the development of strategies to prevent perioperative infections in cataract surgery patients.

Correlation between diabetic peripheral neuropathy and thyroid hormone sensitivity in elderly patients with type 2 diabetes mellitus

BACKGROUND Diabetic peripheral neuropathy(DPN)is a common complication of type 2 diabetes mellitus(T2DM),significantly affecting patients’quality of life and imposing a substantial economic burden.Recent studies have highlighted the role of thyroid hormones in diabetes complications,particularly in elderly patients with T2DM.However,the relationship between thyroid hormone sensitivity and DPN remains unclear.AIM To investigate the correlation between thyroid hormone sensitivity and DPN in elderly patients with T2DM.METHODS In a cohort of 256 elderly patients with T2DM,propensity score matching was used to balance age,sex,and diabetes duration.Clinical data were collected to calculate thyroid hormone sensitivity and analyze its correlation with DPN.A random forest model was used to evaluate the diagnostic value of free triiodothyronine/free thyroxine(FT_(3)/FT_(4))for DPN.RESULTS Patients with DPN had a lower FT_(3)/FT_(4) ratio[(0.302±0.053)vs(0.316±0.049),P=0.040].Quartile stratification showed decreasing DPN prevalence with higher FT_(3)/FT_(4) ratios.Spearman’s correlation analysis showed that a lower FT_(3)/FT_(4) ratio was associated with higher glycated hemoglobin,fasting blood glucose,reduced nerve conduction velocity,and electrical skin conductance.Logistic regression indicated a positive relationship between the median FT_(3)/FT_(4) ratio and bilateral foot electrochemical skin conductance[odds ratio(OR):1.019;95%CI:1.005-1.034;P=0.007]and sural nerve sensory amplitude(OR:1.310;95%CI:1.008-1.703;P=0.043).Receiver operating characteristic analysis using a random forest model showed that incorporating FT_(3)/FT_(4) improved predictive performance for DPN,with an area under the curve of 0.74,sensitivity of 0.79,specificity of 0.64,and accuracy of 0.77.CONCLUSION In elderly patients with T2DM with euthyroidism,a lower FT_(3)/FT_(4) ratio is correlated with increased DPN incidence,affecting both large and small nerve fibers.FT_(3)/FT_(4) is an effective predictor of DPN.

Subpopulations of regulatory T cells are associated with subclinical atherosclerotic plaques,levels of LDL,and cardiorespiratory fitness in the elderly

Background:Atherosclerosis forms the pathological basis for the development of cardiovascular disease.Since pathological processes initially develop without clinically relevant symptoms,the identification of early markers in the subclinical stage plays an important role for initiating early interventions.There is evidence that regulatory T cells(Tregs)are involved in the development of atherosclerosis.Therefore,the present study aimed to identify and investigate associations with Tregs and their subsets in a cohort of healthy elderly individuals with and without subclinical atherosclerotic plaques(SAP).In addition,various lifestyle and risk factors,such as cardiorespiratory fitness,were investigated as associated signatures.Methods:A cross-sectional study was performed in 79 participants(male:n=50;age=63.6±3.7 years;body mass index=24.9±3.1 kg/m2;mean±SD)who had no previous diagnosis of chronic disease and were not taking medication.Ultrasound of the carotids to identify SAP,cardiovascular function measurement for vascular assessment and a cardiorespiratory fitness test to determine peak oxygen uptake were performed.Additionally,tests were conducted to assess blood lipids and determine glucose levels.Immunophenotyping of Tregs and their subtypes(resting(rTregs)and effector/memory(mTregs))was performed by 8-chanel flow cytometry.Participants were categorized according to atherosclerotic plaque status.Linear and logistic regression models were used to analyze associations between parameters.Results:SAP was detected in a total of 29 participants.The participants with plaque were older(64.8±3.6 years vs.62.9±3.5 years)and had higher peripheral systolic blood pressure(133.8±14.7 mmHg vs.125.8±10.9 mmHg).The participants with SAP were characterized by a lower percentage of rTregs(28.8%±10.7%vs.34.6%±10.7%)and a higher percentage of mTregs(40.3%±14.7%vs.30.0%±11.9%).Multiple logistic regression identified age(odds ratio(OR)=1.20(95%confidence interval(95%CI):1.011.42))and mTregs(OR=1.05(95%CI:1.021.10))as independent risk factors for SAP.Stepwise linear regression could reveal an association of peak oxygen uptake(β=0.441),low-density lipoprotein(LDL)(β=0.096),and SAP(β=6.733)with mTregs and LDL(β=0.104)with rTregs.Conclusion:While at an early stage of SAP,the total proportion of Tregs gives no indication of vascular changes,this is indicated by a shift in the Treg subgroups.Factors such as serum LDL or cardiopulmonary fitness may be associated with this shift and may also be additional diagnostic indicators.This could be used to initiate lifestyle-based preventive measures at an early stage,which may have a protective effect against disease progression.

Is recovery enhancement after gastric cancer surgery really a safe approach for elderly patients?

BACKGROUND This study aimed to evaluate the safety of enhanced recovery after surgery(ERAS)in elderly patients with gastric cancer(GC).AIM To evaluate the safety of ERAS in elderly patients with GC.METHODS The PubMed,EMBASE,and Cochrane Library databases were used to search for eligible studies from inception to April 1,2023.The mean difference(MD),odds ratio(OR)and 95%confidence interval(95%CI)were pooled for analysis.The quality of the included studies was evaluated using the Newcastle-Ottawa Scale scores.We used Stata(V.16.0)software for data analysis.RESULTS This study consists of six studies involving 878 elderly patients.By analyzing the clinical outcomes,we found that the ERAS group had shorter postoperative hospital stays(MD=-0.51,I2=0.00%,95%CI=-0.72 to-0.30,P=0.00);earlier times to first flatus(defecation;MD=-0.30,I²=0.00%,95%CI=-0.55 to-0.06,P=0.02);less intestinal obstruction(OR=3.24,I2=0.00%,95%CI=1.07 to 9.78,P=0.04);less nausea and vomiting(OR=4.07,I2=0.00%,95%CI=1.29 to 12.84,P=0.02);and less gastric retention(OR=5.69,I2=2.46%,95%CI=2.00 to 16.20,P=0.00).Our results showed that the conventional group had a greater mortality rate than the ERAS group(OR=0.24,I2=0.00%,95%CI=0.07 to 0.84,P=0.03).However,there was no statistically significant difference in major complications between the ERAS group and the conventional group(OR=0.67,I2=0.00%,95%CI=0.38 to 1.18,P=0.16).CONCLUSION Compared to those with conventional recovery,elderly GC patients who received the ERAS protocol after surgery had a lower risk of mortality.

Predictive modeling for postoperative delirium in elderly patients with abdominal malignancies using synthetic minority oversampling technique

BACKGROUND Postoperative delirium,particularly prevalent in elderly patients after abdominal cancer surgery,presents significant challenges in clinical management.AIM To develop a synthetic minority oversampling technique(SMOTE)-based model for predicting postoperative delirium in elderly abdominal cancer patients.METHODS In this retrospective cohort study,we analyzed data from 611 elderly patients who underwent abdominal malignant tumor surgery at our hospital between September 2020 and October 2022.The incidence of postoperative delirium was recorded for 7 d post-surgery.Patients were divided into delirium and non-delirium groups based on the occurrence of postoperative delirium or not.A multivariate logistic regression model was used to identify risk factors and develop a predictive model for postoperative delirium.The SMOTE technique was applied to enhance the model by oversampling the delirium cases.The model’s predictive accuracy was then validated.RESULTS In our study involving 611 elderly patients with abdominal malignant tumors,multivariate logistic regression analysis identified significant risk factors for postoperative delirium.These included the Charlson comorbidity index,American Society of Anesthesiologists classification,history of cerebrovascular disease,surgical duration,perioperative blood transfusion,and postoperative pain score.The incidence rate of postoperative delirium in our study was 22.91%.The original predictive model(P1)exhibited an area under the receiver operating characteristic curve of 0.862.In comparison,the SMOTE-based logistic early warning model(P2),which utilized the SMOTE oversampling algorithm,showed a slightly lower but comparable area under the curve of 0.856,suggesting no significant difference in performance between the two predictive approaches.CONCLUSION This study confirms that the SMOTE-enhanced predictive model for postoperative delirium in elderly abdominal tumor patients shows performance equivalent to that of traditional methods,effectively addressing data imbalance.

Prevalence and risk factors of diabetes mellitus among elderly patients in the Lugu community

BACKGROUND Age is a significant risk factor of diabetes mellitus(DM).With the develop of population aging,the incidence of DM remains increasing.Understanding the epidemiology of DM among elderly individuals in a certain area contributes to the DM interventions for the local elderly individuals with high risk of DM.AIM To explore the prevalence of DM among elderly individuals in the Lugu community and analyze the related risk factors to provide a valid scientific basis for the health management of elderly individuals.METHODS A total of 4816 elderly people who came to the community for physical examination were retrospectively analyzed.The prevalence of DM among the elderly was calculated.The individuals were divided into a DM group and a non-DM group according to the diagnosis of DM to compare the differences in diastolic blood pressure(DBP)and systolic blood pressure(SBP),fasting blood glucose,body mass index(BMI),waist-to-hip ratio(WHR)and incidence of hypertension(HT),coronary heart disease(CHD),and chronic kidney disease(CKD).RESULTS DM was diagnosed in 32.70%of the 4816 elderly people.The BMI of the DM group(25.16±3.35)was greater than that of the non-DM group(24.61±3.78).The WHR was 0.90±0.04 in the non-DM group and 0.90±0.03 in the DM group,with no significant difference.The left SBP and SBP in the DM group were 137.9 mmHg±11.92 mmHg and 69.95 mmHg±7.75 mmHg,respectively,while they were 126.6 mmHg±12.44 mmHg and 71.15 mmHg±12.55 mmHg,respectively,in the non-DM group.These findings indicate higher SBP and lower DBP in DM patients than in those without DM.In the DM group,1274 patients were diagnosed with HT,accounting for 80.89%.Among the 3241 non-DM patients,1743(53.78%)were hypertensive and 1498(46.22%)were nonhypertensive.The DM group had more cases of HT than did the non-DM group.There were more patients with CHD or CKD in the DM group than in the non-DM group.There were more patients who drank alcohol more frequently(≥3 times)in the DM group than in the non-DM group.CONCLUSION Older adults in the Lugu community are at a greater risk of DM.In elderly individuals,DM is closely related to high BMI and HT,CHD,and CKD.Physical examinations should be actively carried out for elderly people to determine their BMI,SBP,DBP,and other signs,and sufficient attention should be given to abnormalities in the above signs before further diagnosis.

Impact of frailty on outcomes of elderly patients undergoing percutaneous coronary intervention: A systematic review and metaanalysis

BACKGROUND Frailty is a common condition in elderly patients who receive percutaneous coronary intervention(PCI).However,how frailty affects clinical outcomes in this group is unclear.AIM To assess the link between frailty and the outcomes,such as in-hospital complic-ations,post-procedural complications,and mortality,in elderly patients post-PCI.METHODS The PubMed/MEDLINE,EMBASE,Cochrane Library,and Web of Science databases were screened for publications up to August 2023.The primary outcomes assessed were in-hospital and all-cause mortality,major adverse cardiovascular events(MACEs),and major bleeding.The Newcastle-Ottawa Scale was used for quality assessment.RESULTS Twenty-one studies with 739693 elderly patients undergoing PCI were included.Frailty was consistently associated with adverse outcomes.Frail patients had significantly higher risks of in-hospital mortality[risk ratio:3.45,95%confidence interval(95%CI):1.90-6.25],all-cause mortality[hazard ratio(HR):2.08,95%CI:1.78-2.43],MACEs(HR:2.92,95%CI:1.85-4.60),and major bleeding(HR:4.60,95%CI:2.89-7.32)compared to non-frail patients.CONCLUSION Frailty is a pivotal determinant in the prediction of risk of mortality,development of MACEs,and major bleeding in elderly individuals undergoing percutaneous coronary intervention.

Efficacy and safety of endoscopic submucosal dissection for early gastric cancer and precancerous lesions in elderly patients

BACKGROUND With advancements in the development of endoscopic technologies,the endo-scopic submucosal dissection(ESD)has been one of the gold-standard therapies for early gastric cancer.AIM To investigate the efficacy and safety ESD in the treatment of early gastric cancer and precancerous lesions in the elderly patients.METHODS Seventy-eight elderly patients with early gastric cancer and precancerous lesions admitted to the Third Affiliated Hospital of Qiqihar Medical University were se-lected and classified into two groups according to the different surgical therapies they received between January 2021 and June 2022.Among them,39 patients treated with ESD were included in an experimental group,and 39 patients treated with endoscopic mucosal resection(EMR)were included in a control group.We compared the basic intraoperative conditions,postoperative short-term recovery,long-term recovery effects and functional status of gastric mucosa between the two groups;the basic intraoperative conditions included lesion resection,intra-operative bleeding and operation time;the postoperative short-term recovery assessment indexes were length of hospital stay and incidence of surgical complic-ations;and the long-term recovery assessment indexes were the recurrence rate at 1 year postoperatively and the survival situation at 1 year and 3 years postoper-atively;and we compared the preoperative and predischarge serum pepsinogen I(PG I)and PG II levels and PG I/PG II ratio in the two groups before surgery and discharge.RESULTS The curative resection rate and the rate of en bloc resection were higher in the experimental group than in the control group.The intraoperative bleeding volume was higher in the experimental group than in the control group.The operation time was longer in the experimental group than that in the control group,and the rate for base residual focus was lower in the experimental group than that of the control group,and the differences were all statistically significant(all P<0.05).The length of hospital stay was longer in the experi-mental group than in the control group,and the incidence of surgical complications,1-year postoperative recu-rrence rate and 3-year postoperative survival rate were lower in the experimental group than in the control group,and the differences were statistically significant(all P<0.05).However,the difference in the 1-year postoperative survival rate was not statistically significant between the two groups(P>0.05).Before discharge,PG I and PG I/PG II ratio were elevated in both groups compared with the preoperative period,and the above indexes were higher in the experimental group than those in the control group,and the differences were statistically significant(both P<0.05).Moreover,before discharge,PG II level was lower in both groups compared with the preoperative period,and the level was lower in the experimental group than in the control group,and the differences were all statistically significant(all P<0.05).CONCLUSION Compared with EMR,ESD surgery is more thorough.It reduces the rate of base residual focus,recurrence rate,surgical complications,and promotes the recovery of gastric cells and glandular function.It is safe and suitable for clinical application.

Effect of remimazolam vs. propofol on hemodynamics during general anesthesia induction in elderly patients: Single-center, randomized controlled trial

The current study aimed to compare the effects between remimazolam and propofol on hemodynamic stability during the induction of general anesthesia in elderly patients.We used propofol at a rate of 60 mg/(kg·h)in the propofol group(group P)or remimazolam at a rate of 6 mg/(kg·h)in the remimazolam group(group R)for the induction.A processed electroencephalogram was used to determine whether the induction was successful and when to stop the infusion of the study drug.We measured when patients entered the operating room(T_(0)),when the induction was successful(T_(1)),and when before(T_(2))and 5 min after successful endotracheal intubation(T_(3)).We found that mean arterial pressure(MAP)was lower at T_(1–3),compared with T_(0) in both groups,but higher at T_(2) in the group R,whileΔMAP_(T0–T2) andΔMAP_(max) were smaller in the group R(ΔMAP_(T0–T2):the difference between MAP at time point T_(0) and T_(2),ΔMAP_(max):the difference between MAP at time point T_(0) and the lowest value from T_(0) to T_(3)).Cardiac index and stroke volume index did not differ between groups,whereas systemic vascular resistance index was higher at T_(1–3) in the group R.These findings show that remimazolam,compared with propofol,better maintains hemodynamic stability during the induction,which may be attributed to its ability to better maintain systemic vascular resistance levels.

Qualitative exploration of home life experiences and care needs among elderly patients with temporary intestinal stomas

BACKGROUND This study employed a phenomenological research approach within qualitative research to explore the challenges encountered by elderly individuals with temporary colostomies in managing their daily lives and care needs.Protecting the anus surgery combined with temporary colostomy has emerged as a prevalent treatment modality for low rectal cancer.However,the ileostomy is susceptible to peri-stoma skin complications,as well as fluid,electrolyte,and nutritional imbalances,posing challenges to effective management.The successful selfmanagement of patients is intricately linked to their adjustment to temporary colostomy;nonetheless,there remains a dearth of research examining the factors influencing self-care among temporary colostomy patients and the obstacles they confront.AIM To investigate the lived experiences,perceptions,and care requirements of temporary colostomy patients within their home environment,with the ultimate goal of formulating a standardized management protocol.METHODS Over the period of June to August 2023,a purposive sampling technique was utilized to select 12 patients with temporary intestinal stomas from a tertiary hospital in Shanghai,China.Employing a phenomenological research approach,a semi-structured interview guide was developed,and qualitative interviews were conducted using in-depth interview techniques.The acquired data underwent coding,analysis,organization,and summarization following Colaizzi’s seven-step method.RESULTS The findings of this study revealed that the experiences and needs of patients with temporary intestinal stomas can be delineated into four principal themes:Firstly,Temporary colostomy patients bear various burdens and concerns about the uncertainty of disease progression;secondly,patients exhibit limited self-care capabilities and face information deficits,resulting in heightened reliance on healthcare professionals;thirdly,patients demonstrate the potential for internal motivation through proactive self-adjustment;and finally,patients express a significant need for emotional and social support.CONCLUSION Home-living patients with temporary intestinal stomas confront multifaceted challenges encompassing burdens,inadequate self-care abilities,informational deficits,and emotional needs.Identifying factors influencing patients’self-care at home and proposing strategies to mitigate barriers can serve as a foundational framework for developing and implementing nursing interventions tailored to the needs of patients with temporary intestinal stomas.

Effect of infarct location and volume on cognitive dysfunction in elderly patients with acute insular cerebral infarction

BACKGROUND The aging of the population has become increasingly obvious in recent years,and the incidence of cerebral infarction has shown an increasing trend annually,with high death and disability rates.AIM To analyze the effects of infarct location and volume on cognitive dysfunction in elderly patients with acute insular cerebral infarction.METHODS Between January 2020 and December 2023,we treated 98 cases of elderly acute insula,patients with cerebral infarction in the cerebral infarction acute phase(3-4 weeks)and for the course of 6 months in Montreal Cognitive Assessment Scale(MoCA)for screening of cognition.Notably,58 and 40 patients were placed in the cognitive impairment group and without-cognitive impairment group,respec-tively.In patients with cerebral infarction,magnetic resonance imaging was used to screen and clearly analyze the MoCA scores of two groups of patients with different infarctions,the relationship between the parts of the infarction volume,and analysis of acute insula cognitive disorder in elderly patients with cerebral RESULTS The number of patients with cognitive impairment in the basal ganglia and thalamus was significantly higher than that without cognitive impairment(P<0.05).The total infarct volume in the cognitive impairment group was higher than that in the non-cognitive impairment group,and the difference was statistically significant(P<0.05).The infarct volumes at different sites in the cognitive impairment group was higher than in the non-cognitive impairment group(P<0.05).In the cognitive impairment group,the infarct volumes in the basal ganglia,thalamus,and mixed lesions were negatively correlated with the total MoCA score,with correlation coefficients of-0.67,-0.73,and-0.77,respectively.CONCLUSION In elderly patients with acute insular infarction,infarction in the basal ganglia,thalamus,and mixed lesions were more likely to lead to cognitive dysfunction than in other areas,and patients with large infarct volumes were more likely to develop cognitive dysfunction.The infarct volume in the basal ganglia,thalamus,and mixed lesions was significantly negatively correlated with the MoCA score.

Magnetic resonance imaging combined with serum endolipin and galactagoglobin-3 to diagnose cerebral infarction in the elderly with diabetes mellitus

BACKGROUND Magnetic resonance imaging(MRI)combined with serum endothelin and galactagoglobin-3(Gal-3)can improve the clinical diagnosis of diabetes mellitus complicated with cerebral infarction.AIM To analyze the clinical value of MRI combined with serum endolipin and Gal-3 for the diagnosis of cerebral infarction in the elderly with diabetes mellitus.METHODS One hundred and fifty patients with acute cerebral infarction hospitalized between January 2021 and December 2023 were divided into two groups according to comorbid diabetes mellitus,including 62 and 88 cases in the diabetic and nondiabetic cerebral infarction groups.Serum samples were collected to detect the expression of serum endolipoxins,and Gal-3,and cranial MRI was performed at admission.Differences between the two groups were compared to analyze the diagnostic value of these parameters.RESULTS Serum endolipin and Gal-3 expression were higher in the diabetic cerebral infarction group(P<0.05).The arterial wall area,vessel area,normalized wall index,and lumen stenosis rate were higher in the diabetic cerebral infarction group,while the rate of arterial lumen moderate and severe stenosis was 48.39% higher(36.36%,P<0.05).The percentage of large(29.03%)and multiple infarcts(33.87%)in the diabetic cerebral infarction group was higher(13.64% and 20.45%),and the incidence rate of lacunar infarcts was lower(37.10%vs 65.91%)(P<0.05).The total incidence of arterial plaque in patients in the diabetic cerebral infarction group was 96.77% higher(69.32%),while the incidence of necrotic lipid core plaque was 58.06%higher(26.14%)(P<0.05).Receiver operating characteristic curve analysis was performed to assess the diagnosis utility of these techniques.MRI in combination with serum endoglin and Gal-3 had the highest area under the curve,the Yoden index,sensitivity and specificity(P<0.05).CONCLUSION The expression of serum endolipin and Gal-3 in elderly patients with diabetes mellitus with cerebral infarction showed an elevated trend,and the degree of luminal stenosis was severe.MRI predominantly revealed large and multiple infarct foci.This combined index examination can improve the clinical diagnosis of diabetes mellitus combined with cerebral infarction.

Clinical significance of preoperative nutritional status in elderly gastric cancer patients undergoing radical gastrectomy:A singlecenter retrospective study

BACKGROUND The population of elderly patients with gastric cancer is increasing,which is a major public health issue in China.Malnutrition is one of the greatest risk factors for adverse clinical outcomes in elderly patients with gastric cancer.AIM To investigate the preoperative nutritional status and its association with delayed discharge of elderly gastric cancer patients following radical gastrectomy.METHODS A total of 783 patients aged 65 years and older harboring gastric adenocarcinoma and following radical gastrectomy were retrospectively analyzed from the prospectively collected database of Zhongshan Hospital of Fudan University between January 2018 and May 2020.RESULTS The overall rate of malnutrition was 31.8%.The incidence of postoperative complications was significantly higher in the malnourished group compared to the well-nourished group(P<0.001).Nutritional characteristics in the malnourished group,including body mass index,prognostic nutritional index(PNI),albumin,prealbumin,and hemoglobin,were all significantly lower than those in the well-nourished group.The percentage of patients who received postoperative total nutrient admixture was lower in the malnourished group compared to the wellnourished group(22.1%vs 33.5%,P=0.001).Age≥70 years(HR=1.216,95%CI:1.048-1.411),PNI<44.5(HR=1.792,95%CI:1.058-3.032),operation time≥160 minutes(HR=1.431,95%CI:1.237-1.656),and postoperative complications grade III or higher(HR=2.191,95%CI:1.604-2.991)were all recognized as independent risk factors associated with delayed discharge.CONCLUSION Malnutrition is relatively common in elderly patients undergoing gastrectomy.Low PNI is an independent risk factor associated with delay discharge.More strategies are needed to improve the clinical outcome of these patients.

Sleep quality in middle-aged and elderly hemodialysis patients:Impact of a structured nursing intervention program

BACKGROUND Poor sleep quality is common among hemodialysis patients and can significantly impact their well-being.This study aimed to evaluate the effectiveness of a structured nursing intervention program in improving sleep quality in middleaged and elderly hemodialysis patients.AIM To evaluate the impact of nursing intervention on sleep quality in hemodialysis patients.METHODS This cross-sectional study was conducted in a tertiary hospital,the First Affiliated Hospital of Nanchang University,in 2023.This study included 105 middle-aged and elderly hemodialysis patients aged≥45 years who underwent maintenance hemodialysis for at least 3 mo,utilizing the Pittsburgh Sleep Quality Index(PSQI)to identify poor sleepers.Those identified underwent a 12-wk nursing intervention program focusing on education,relaxation techniques,and counseling.Post-intervention,sleep quality was reassessed using the PSQI.RESULTS The study found that 68.6%of hemodialysis patients were poor sleepers.Following the 12-wk nursing intervention program,there was a significant decrease in the mean global PSQI score from 8.9±3.2 to 5.1±2.7(P<0.001),indicating improved sleep quality.This demonstrated the effectiveness of the structured nursing intervention in enhancing sleep quality for middle-aged and elderly hemodialysis patients.CONCLUSION The structured nursing intervention program focusing on sleep hygiene education,relaxation techniques,and counseling effectively improved sleep quality among middle-aged and elderly hemodialysis patients.The significant decrease in the mean global PSQI score post-intervention indicates the positive impact of tailored nursing interventions in addressing poor sleep quality in this patient population.These findings emphasize the importance of implementing targeted nursing interventions to enhance the quality of life for hemodialysis patients by addressing the prevalent issue of poor sleep quality.
