The maximum oxygen consumption at the peak of the exercise test(VO2peak), iron metabolism parameters and respiratory activity of peripheral blood mononuclear cell mitochondria were assessed.Results Among the patients, a half of individuals were diagnosed with iron deficiency. Subgroups of patients with different HF severity did not significant differ in VO2peak(P=0.209), serum iron(P=0.468) and ferritin(P=0.235) levels. But there was a trend in increasing in these parameters with increasing NYHA HF functional class. Respiratory control coefficient(RC) in NADdependent and FAD-dependent mitochondrial oxidation were lower in patients with NYHA HF Ⅲ functional class compared to individuals with NYHA HF I functional class(P=0.028 and P=0.040, respectively). Serum iron(P=0.026), ferritin(P=0.045)levels, transferrin saturation(P=0.006) were negatively correlated with RC in NAD-dependent mitochondrial oxidation.Conclusions In aggravation of ischemic HF NYHA FC, there is a decrease in RC of PBMC mitochondria during the oxidation of NAD-dependent and FAD-dependent substrates. In the whole sample, patients with laboratory-confirmed iron deficiency accounted a half of the total number. Iron metabolism parameters had a paradoxical inverse relationship with the level of RC in PBMC mitochondria of patients with HF.展开更多

文摘Heart failure(HF)with preserved ejection fraction(HFpEF)has exceeded HF with reduced ejection fraction(HFrEF),becoming the most common type of HF.Unlike HFrEF,HFpEF is primarily a chronic low-grade inflammatory process closely associated with metabolic disorders.The coexistence of HFpEF and metabolic dysfunction-associated steatotic liver disease(MASLD)presents significant clinical challenges due to shared metabolic pathophysiology and complex inter-play.Management strategies for HFpEF and MASLD remain challenging.Sodium-glucose cotransporter 2 inhibitors have shown benefits in managing both conditions.Additionally,glucagon-like peptide-1 receptor agonists are being actively investigated for their potential benefits,particularly in MASLD.A comprehensive,patient-centered approach that combines metabolic and cardiova-scular care is essential for improving outcomes in patients with HFpEF and MASLD,addressing the global metabolic health challenges.

文摘Software-defined networking(SDN)is an innovative paradigm that separates the control and data planes,introducing centralized network control.SDN is increasingly being adopted by Carrier Grade networks,offering enhanced networkmanagement capabilities than those of traditional networks.However,because SDN is designed to ensure high-level service availability,it faces additional challenges.One of themost critical challenges is ensuring efficient detection and recovery from link failures in the data plane.Such failures can significantly impact network performance and lead to service outages,making resiliency a key concern for the effective adoption of SDN.Since the recovery process is intrinsically dependent on timely failure detection,this research surveys and analyzes the current literature on both failure detection and recovery approaches in SDN.The survey provides a critical comparison of existing failure detection techniques,highlighting their advantages and disadvantages.Additionally,it examines the current failure recovery methods,categorized as either restoration-based or protection-based,and offers a comprehensive comparison of their strengths and limitations.Lastly,future research challenges and directions are discussed to address the shortcomings of existing failure recovery methods.
文摘Falls remain a prevalent source of injury in daily life and underlying aetiology of falls are often complex and multi-factorial.[1,2]Older persons living with heart failure(OPLHF)are of a particular interest when discussing falls as multiple factors associated with heart failure(HF)aetiology and treatment are assumedly implicated in falls occurrence.A retrospective study reported a 14%increased risk of falls among OPLHF,and prospective data has shown that up to 40%of HF patients may experience a fall within a year from diagnosis.

文摘INTRODUCTION.On May 1st,2024,around 2:10 a.m.,a catastrophic collapse occurred along the Meilong Expressway near Meizhou City,Guangdong Province,China,at coordinates 24°29′24″N and 116°40′25″E.This collapse resulted in a pavement failure of approximately 17.9 m in length and covering an area of about 184.3 m^(2)(Chinanews,2024).
文摘Background Patients aged 85 years or older admitted for heart failure(HF)have increased enormously due to improved survival in this disease.However,few studies assess the characteristics,treatments,and prognosis of very elderly patients admitted for acute HF.Methods This study is a retrospective analysis of the EPICTER registry,that included patients admitted for acute HF in 74 Spanish hospitals.For this analysis,a total of 1887 patients were included and divided into 2 groups:85 years or older(very elderly,680 patients)and those under 85 years.Results Compared to patients<85 years,very elderly patients were more frequently women,had more hypertension and disease cerebrovascular disease,and less presence of chronic obstructive pulmonary disease(COPD),diabetes,and acute myocardial infarction.There were no differences in symptoms,except for delirium,significantly more common in very elderly patients.Management of these patients was more conservative and died more than the younger ones(41%vs.25%,P<0.001).The predictor variables of mortality in very elderly patients were the presence of COPD and peripheral arterial disease,delirium,and estimated survival of less than 6 months assessed by the physician in charge of the patient care.Conclusion Very elderly patients admitted for HF differ from younger ones in comorbidities,management,and symptoms,and have higher mortality.The presence of delirium,peripheral arterial disease,and COPD worsen the prognosis in these patients and can help to adapt the therapeutic effort and place emphasis on adequate symptom control.
文摘BACKGROUND Post-pancreaticoduodenectomy(PD)intestinal failure(IF)is rare and associated with poor outcomes.To our knowledge,the role of intestinal transplantation(ITx)as a rescue treatment for this complication has never been reported.CASE SUMMARY A 42-year-old female with a benign neurilemmoma of the duodenum underwent PD.Her superior mesenteric vein(SMV)was injured during surgery and required reconstruction.She experienced SMV thrombosis and bowel gangrene requiring massive bowel resection.Consequently,she developed short gut syndrome and an enterocutaneous fistula,leading to prolonged hospitalization for wound care and total parenteral nutrition(TPN)support.She was referred to our hospital for ITx evaluation.Upon arrival,she had cholestasis due to IF-associated liver disease.After gastrointestinal(GI)reconstruction to restore GI continuity,she was eligible for multi-visceral transplantation(MVTx).The anticipated allograft included the stomach,small intestine,liver,pancreas,and duodenum.She found a suitable donor after two years of waiting.The MVTx procedure was straightforward with signs of immediate function.Enteral feeding was initiated on postoperative day(POD)7.TPN weaning was achieved on POD 28,and the patient was discharged on POD 69.Two years post-MVTx,she is healthy with excellent graft function.To our knowledge,this is the first case report on MVTx as the treatment for fatal post-PD complications and also the first reported case of ITx in Southeast Asia.CONCLUSION Post-PD IF is rare and lethal.Intestinal and MVTx might be a rescue treatment for IF after GI surgery in eligible patients.
文摘BACKGROUND Acute decompensated heart failure(ADHF)is one of the leading causes of mortality,highlighting the importance of early identification of high-risk patients.The fibrosis-5(FIB-5)index,traditionally used to evaluate hepatic fibrosis,may hold prognostic value in ADHF patients by reflecting systemic congestion,inflammation,and organ dysfunction.The hypothesis of this study is that the FIB-5 index is an independent predictor of 1-month mortality in patients with ADHF.METHODS This retrospective study included 155 patients diagnosed with ADHF between 2020 and 2024.Patients were divided into two groups based on their left ventricular ejection fraction(LVEF≤40%or LVEF>50%).Survival was monitored for one month,and clinical,biochemical,and echocardiographic parameters were compared between survivors and death.Logistic regression and receiver operating characteristic curve analyses were performed to assess the prognostic value of the FIB-5 index.RESULTS During the 1-month follow-up,66 patients(42.6%)died.The mean FIB-5 index was significantly lower in non-survivors(−10.46±6.93)compared to survivors(−8.10±6.67)(P=0.03).Multivariate regression analysis identified the FIB-5 index as an independent predictor of 1-month mortality(OR=1.089,95%CI:1.022–1.160,P=0.009).The receiver operating characteristic curve analysis demonstrated an area under the curve of 0.609(95%CI:0.51–0.699)with sensitivity of 59.6%and specificity of 63.4%.Kaplan-Meier survival analysis revealed significantly higher mortality rates among patients with lower FIB-5 values(log-rank:7.887,P=0.005).CONCLUSIONS The FIB-5 index is an independent predictor of 1-month mortality in ADHF patients.Its low cost,non-invasive nature,and ability to reflect systemic inflammation and congestion make it a promising tool for risk stratification.Prospective studies are needed to validate its utility in clinical practice and evaluate its role in guiding therapeutic decisions.

文摘Krishnan et al’s article is a comprehensive and vigorous retrospective cohort study regarding the association between obesity and clinical outcomes in acute liver failure(ALF).Among patients with ALF in the United States,mean body mass index(BMI)was significantly greater in those who underwent liver transplantation or who died than among survivors,although acetaminophen induced ALF was the most common etiology.A high BMI was associated with renal failure and high grades of hepatic encephalopathy.The prevalence of obesity and its related fatty liver diseases,such as metabolic dysfunction-associated fatty liver disease/metabolic dysfunction-associated steatotic liver disease and metabolic dysfunction-associated steatohepatitis,has increased worldwide.Obesity is related to increased serum cytokines and immune abnormalities.These findings may explain why ALF in patients with high BMI is associated with worse clinical outcomes.Further studies are needed to determine the associations among BMI,ALF and acute-on-chronic liver failure.
文摘This paper investigates the mechanisms of rock failure related to axial splitting and shear failure due to hoop stresses in cylindrical specimens.The hoop stresses are caused by normal viscous stress.The rheological dynamics theory(RDT)is used,with the mechanical parameters being determined by P-and S-wave velocities.The angle of internal friction is determined by the ratio of Young's modulus and the dynamic modulus,while dynamic viscosity defines cohesion and normal viscous stress.The effect of frequency on cohesion is considered.The initial stress state is defined by the minimum cohesion at the elastic limit when axial splitting can occur.However,as radial cracks grow,the stress state becomes oblique and moves towards the shear plane.The maximum and nonlinear cohesions are defined by the rock parameters under compressive strength when the radial crack depth reaches a critical value.The efficacy and precision of RDT are validated through the presentation of ultrasonic measurements on sandstone and rock specimens sourced from the literature.The results presented in dimensionless diagrams can be utilized in microcrack zones in the absence of lateral pressure in rock masses that have undergone disintegration due to excavation.

文摘Dear Editor,This letter focuses on the remaining useful life(RUL)prediction task under limited labeled samples.Existing machine-learning-based RUL prediction methods for this task usually pay attention to mining degradation information to improve the prediction accuracy of degradation value or health indicator for the next epoch.However,they ignore the cumulative prediction error caused by iterations before reaching the failure point.
文摘BACKGROUND The central link between septic shock and acute skin failure(ASF)is the inflammatory response,which occurs throughout disease progression and can lead to systemic inflammatory response syndrome.Patients often experience bad moods,sleep disorders,and other health issues.Despite recognizing these factors,no studies have examined the correlation between inflammatory factors,lactic acid levels,ASF,mood disturbances,and sleep quality in critically ill patients.We hypothesize that higher levels of inflammatory factors and lactic acid are associated with more severe ASF and poorer mood and sleep quality,which may inform clinical treatment for septic shock and ASF.AIM To explore the relationship between inflammatory factors,lactic acid levels,the severity of ASF,bad mood,and sleep quality.METHODS The retrospective study included 150 patients with septic shock from the Second Hospital of Dalian Medical University,categorized into ASF(n=35)or non-ASF groups(n=115).We compared the peripheral blood inflammatory factors,including tumor necrosis factor-α(TNF-α),C-reactive protein(CRP),interleukin-6(IL-6),lactic acid levels,skin mottling score(SMS),modified early warning score(MEWS),self-rating depression scale(SDS),self-rating anxiety scale(SAS),and Pittsburgh sleep quality index(PSQI)scores.Pearson correlation analysis assessed relationships among these variables.RESULTS The ASF group had significantly higher levels of CRP(19.60±4.10 vs 15.30±2.96 mg/mL),IL-6(298.65±48.65 vs 268.66±33.66 pg/L),procalcitonin,lactic acid(8.42±2.32 vs 5.70±1.27 mmol/L),SMS[0(0,1)vs 3(2,3)],MEWS(9.34±1.92 vs 6.48±1.96),SAS(61.63±12.03 vs 53.71±12.48),SDS(60.17±12.64 vs 52.27±12.64),and PSQI scores(14.23±3.94 vs 8.69±2.46)compared with the non-ASF group(all P<0.001).Pearson correlation analysis revealed that IL-6,CRP,TNF-α,and lactic acid were positively correlated with SMS,MEWS,SAS,SDS,and PSQI scores(P<0.05).CONCLUSION Peripheral blood levels of IL-6,CRP,TNF-α,and lactic acid correlate positively with SMS,MEWS,SAS,SDS,and PSQI in critically ill patients with ASF.

文摘Objectives To compare respiratory parameters of peripheral blood mononuclear cell mitochondria and iron metabolism indicators in patients with different NYHA functional classes of ischemic heart failure(HF).Methods This single center, prospective, non-blinded study enrolled 20 patients with diagnosed chronic HF of ischemic genesis with reduced and mildly reduced left ventricle ejection fraction. The maximum oxygen consumption at the peak of the exercise test(VO2peak), iron metabolism parameters and respiratory activity of peripheral blood mononuclear cell mitochondria were assessed.Results Among the patients, a half of individuals were diagnosed with iron deficiency. Subgroups of patients with different HF severity did not significant differ in VO2peak(P=0.209), serum iron(P=0.468) and ferritin(P=0.235) levels. But there was a trend in increasing in these parameters with increasing NYHA HF functional class. Respiratory control coefficient(RC) in NADdependent and FAD-dependent mitochondrial oxidation were lower in patients with NYHA HF Ⅲ functional class compared to individuals with NYHA HF I functional class(P=0.028 and P=0.040, respectively). Serum iron(P=0.026), ferritin(P=0.045)levels, transferrin saturation(P=0.006) were negatively correlated with RC in NAD-dependent mitochondrial oxidation.Conclusions In aggravation of ischemic HF NYHA FC, there is a decrease in RC of PBMC mitochondria during the oxidation of NAD-dependent and FAD-dependent substrates. In the whole sample, patients with laboratory-confirmed iron deficiency accounted a half of the total number. Iron metabolism parameters had a paradoxical inverse relationship with the level of RC in PBMC mitochondria of patients with HF.

文摘Rock slopes with large intersection angles between the strikes of strata and surface(RS-LISS)represent a unique type of layered rock slope.These slopes are usually considered to be well stabilized and less prone to landslides.However,when such slopes contain a significant number of discontinuities,their stability is greatly weakened.This study provided innovative insights into the stability of RS-LISS and conducted an in-depth investigation of their step-path failure mechanisms.The Riyi landslide on the eastern margin of the Qinghai-Tibet Plateau,China,was taken as a typical case and detailed investigations of geological structure and deformation characteristics of the slope were conducted by means of slope mapping,core drilling,and exploratory adits.A large number of steep-dip and gentle-dip joints were discovered in the slope,along with several critical discontinuities such as faults.Analysis shows that the tectonic stresses and river downcutting over geological time played significant roles in the formation of these discontinuities.Based on the investigation results,a numerical model of DFN for the Riyi landslide was developed.The simulation results indicated that the slope could develop a sliding surface characterized by a steep back and a gentle base,formed through the stepped interconnection of various discontinuities.Additionally,the deformation of the rock mass mainly originated from the major fault,progressively extending downward.The sliding mass may slide suddenly as a whole along the stepped bottom surface,with the compressional fracture zones as lateral boundaries,presenting a"drawer-like"movement towards the free surface.
文摘BACKGROUND Advanced heart failure and transplant(AHFTC)teams are crucial in the management of patients in cardiogenic shock.We sought to explore the impact of AHFTC physicians on outcomes in patients receiving extracorporeal membrane oxygenation(ECMO)support.AIM To determine whether outcomes differ in the care of ECMO patients when AHFTC physicians serve in a primary vs consultative role.METHODS We conducted a retrospective cohort study of 51 patients placed on veno-venous(VV)and veno-arterial(VA)ECMO between January 2015 and February 2023 at our institution.We compared ECMO outcomes between teams managed primarily by intensivists vs teams where AHFTC physicians played a direct role in ECMO management,including patient selection.Our primary outcome measure was survival to 30 days post hospital discharge.RESULTS For combined VA and VV ECMO patients,survival to 30 days post discharge in the AHFTC cohort was significantly higher(67%vs 30%,P=0.01),largely driven by a significantly increased 30-day post discharge survival in VA ECMO patients in the AHFTC group(64%vs 20%,P=0.05).CONCLUSION This study suggests that patients in shock requiring VA ECMO support may have improved survival 30 days after hospital discharge when an AHFTC team serves in a direct role in the selection and management of patients.Further studies are needed to validate this impact.
