Abstract 17260: Endothelium-Targeted Nanoparticle Delivery of FOXM1 Reactivates Aging-Impaired Endothelial Regeneration for Vascular Repair and Inflammatory Lung Injury Resolution: Precision Gene Therapy of Acute Respiratory Distress Syndrome

Introduction: Aging is a major risk factor of high incidence and increased mortality of acute respiratory distress syndrome (ARDS). However, the underlying molecular mechanisms remain elusive and there is no effective therapy for ARDS. Hypothesis: Impaired endothelial regeneration and vascular repair in aged lungs causes persistent lung injury leading to high incidence of ARDS and high mortality in elderly patients following sepsis challenge. Methods: Genetic lineage tracing was employed to determine the cell origin of endothelial regeneration. Aged Foxm1Tg mice was used for assessing the role of FoxM1 in activating endothelial regeneration. Endothelium-targeted nanoparticles were employed to deliver FOXM1 gene selectively to endothelial cells (ECs) in aged mice. Methylation analysis was employed to determine how aging impairs FoxM1 expression. Results: Genetic lineage tracing study showed that endothelial regeneration was mediated by lung endothelial proliferation in adult mice whereas this intrinsic regenerative program was impaired in aged mice. Expression of FoxM1, an important mediator of endothelial regeneration in young adult mice, was not induced in lungs of aged mice due to aging-induced hypermethylation of the Foxm1 promoter. Transgenic FOXM1 expression or in vivo endothelium-targeted nanoparticle delivery of FOXM1 gene reactivated endothelial regeneration, normalized vascular repair and promoted survival of aged mice following sepsis. Furthermore, nanoparticle delivery of FoxM1 gene selectively in lung ECs also reactivated endothelial regeneration in aged mice, supporting the novel concept of precision gene therapy. In COVID-19 lung autopsy samples, FOXM1 expression was not induced in vascular ECs of elderly patients in contrast to mid-age patients, validating the clinical relevance of our findings. Conclusions: We have demonstrate that persistent lung injury and high mortality in aged mice following sepsis challenge is ascribed to impaired endothelial regeneration and vascular repair. Therapeutic reactivation of FoxM1-dependent endothelial regeneration and vascular repair represents a potential effective therapy for elderly ARDS patients by endothelium-targeted nanoparticle delivery of FOXM1 gene.

Abstract 13013: Predictors of Mortality in Elderly Patients Admitted With Takotsubo Cardiomyopathy and a History of Depression

Introduction: Takotsubo cardiomyopathy(TC) (broken heart syndrome or stress-induced cardiomyopathy) is usually a catecholamine-driven weakening of the left ventricle wall motion due to severe emotional or physical stress. It presents as an acute onset of reversible symptoms resembling acute coronary syndrome without occluded coronary arteries. As emotional stressors often trigger the condition, we aim to evaluate factors that can cause hospital death following admission for TC among elderly patients with depression. Methods: Our study group assessed mortality risk factors in patients ages ≥60 years with a diagnosis of TC and depression from the 2016-2020 National Inpatient Sample. Results: There were a total of 26375 elderly patients who had a diagnosis of TC. Amongst them, 25225 (95.6%) did not survive their hospitalization. After adjusting for variables, we found several factors that increased the odds of all-cause mortality in these patients, such as cirrhosis (aOR 2.093, p<0.01), peripheral vascular disease (PVD)(aOR 1.319, p=0.017), and events of Acute Kidney Injury (AKI)(aOR 3.072, p<0.01). Meanwhile, Females (vs. Males, aOR 0.597, p<0.01), the presence of hypertension(aOR 0.854, p=0.029), lipid disorder (aOR 0.696, p<0.01), smoking (aOR0.74, p<0.01), history of stroke (aOR 0.612, p<0.01) or history of myocardial infarction (aOR 0.536, p<0.01) showed lower odds of mortality among elderly patients admitted with TC. No disparities based on race or insurance forms were observed (Table 1). Conclusions: Our analysis found that patients ages ≥ 60 years with TC had poorer outcomes if they had cirrhosis, PVD, or AKI. While reduced odds of death were seen in females and patients with specific comorbidities such as smoking, hypertension, lipid disorder, history of stroke, or myocardial infarction, further studies, adjusting for the length of diagnosis and the medications being used, should be encouraged to expand and understand our results better.

Risk factors for short-term mortality in elderly hip fracture patients with complicated heart failure in the ICU: A MIMIC-IV database analysis using nomogram

BackgroundHip fracture is a prevalent and hazardous injury among the elderly population that often results in intensive care unit (ICU) admission due to various complications, despite advanced medical science. One common complication experienced in the ICU by elderly hip fracture patients is heart failure, which significantly impacts short-term survival rates. Currently, there is a deficit of adequate predictive models to forecast the short-term risk of death following heart failure for elderly hip fracture patients in the ICU. This study aims to identify independent risk factors for all-cause mortality within 30 days for elderly patients with hip fractures and heart failure while in the ICU in order to develop a predictive model.MethodA total of 641 elderly patients with hip fractures combined with heart failure were recruited from the Medical Information Mart for Intensive Care IV dataset and randomized to the training and validation sets. The primary outcome was all-cause mortality within 30 days. The least absolute shrinkage and selection operator regression was used to reduce data dimensionality and select features. Multivariate logistic regression was used to build predictive models. Consistency index (C-index), receiver operating characteristic curve, and decision curve analysis (DCA) were used to measure the predictive performance of the nomogram.ResultOur results showed that these variables including MCH, MCV, INR, monocyte percentage, neutrophils percentage, creatinine, and combined sepsis were independent factors for death within 30 days in elderly patients with hip fracture combined with heart failure in the ICU. The C-index was 0.869 (95% CI 0.823–0.916) and 0.824 (95% CI 0.749–0.900) for the training and validation sets, respectively. The results of the area under the curve and decision curve analysis (DCA) confirmed that the nomogram performed well in predicting elderly patients with hip fractures combined with heart failure in the ICU.ConclusionWe developed a new nomogram model for predicting 30-day all-cause mortality in elderly patients with hip fractures combined with heart failure in the ICU, which could be a valid and useful clinical tool for clinicians for targeted treatment and prognosis prediction.

Use of Prephase Steroids in Older Patients Treated for Diffuse Large B-Cell Lymphoma

Background Treatment related morbidity and mortality (TRM) are significant contributors to overall morbidity and mortality for elderly patients with diffuse large B-cell lymphoma (DLBCL). Several studies have shown that TRM is greatest during the first two cycles of treatment. While attenuated doses of standard-of-care treatment regimens (such as R-mini-CHOP) are commonly used to reduce TRM, one additional strategy that has shown promise is the use of glucocorticoids prior to initiation of systemic chemoimmunotherapy (CIT). This approach, defined as prephase steroid use, has been evaluated in small studies, primarily single-center and retrospective in nature. However, older patients with comorbidities are both at greatest risk of TRM and less frequently included in clinical trials. Moreover, patient populations may differ across clinical settings. We conducted an analysis of prephase steroid use in a broader, real-world population treated across multiple centers. Methods We used longitudinal data from the US nationwide, Flatiron Health electronic health record-derived de-identified database. We included patients aged >60 with a diagnosis of DLBCL treated with CIT. This included high-grade B-cell lymphoma, but omitted diagnoses of Burkitt's or primary CNS lymphoma. We utilized a prespecified data analysis plan to determine whether outcomes differed by our exposure of interest, use of prephase steroids. The primary outcome measure was the combined endpoint of time to start of next treatment or death (real-world time to next treatment [rwTTNT]). The secondary outcome was real-world overall survival (rwOS). Outcomes were measured from frontline treatment start date. We also assessed rates of dose delays to evaluate whether prephase steroid use facilitates the maintenance of dose intensity. Prephase steroid use (the exposure) was defined as an order or administration for steroids occurring 5-21 days prior to the start of antineoplastic therapy (excluding steroids used as part of a standard treatment regimen). Patients were stratified by use of anthracycline-based CIT, with sensitivity analyses conducted limited to the anthracycline CIT group. To reduce confounding, we used propensity score-based inverse probability of treatment weighting (IPTW) for the primary analysis. Time to event endpoints were assessed using weighted Kaplan-Meier curves and log-rank tests. Odds of dose delays were assessed using weighted logistic regression. Results We included 3587 patients meeting our criteria, of whom 569 (15.9%) received prephase steroids prior to first-line CIT. A greater percentage of patients treated with anthracycline-based CIT received prephase steroids as compared to those treated with non-anthracyline CIT: 16.3% vs 12.4%, respectively (Table 1). In adjusted analysis using IPTW, there was no significant difference in the rwTTNT by prephase steroid use (p=0.807, Figure 1). Median rwTTNT was 41.2 months (95% CI, 34.6 to 52.4) vs 40.8 months (95% CI, 35.1 to 46.7) with and without prephase steroids, respectively. There was no difference in median rwOS by prephase steroid use: 65.7 months (95% CI, 52.4 to 84.8) vs 74.8 months (95% CI, 67.4 to 82.5) (p=0.707). No differences were seen in sensitivity analyses limiting to patients treated with anthracycline-based CIT. For dose delays, adjusted analysis showed a numerically lower odds of dose delay in patients administered prephase steroids in the total study population: 40.6% vs 50.7% (OR 0.796; p=0.0569). Discussion In this retrospective study of 3587 real-world, elderly patients with DLBCL, prephase steroid use within 21 days of induction CIT did not improve the rwTTNT or rwOS. There was a suggestion that use of prephase steroids may promote maintenance of dose intensity by reducing delays in CIT administration, though this finding did not reach statistical significance. The strengths of this analysis included use of a large, nationwide, real-world dataset and propensity score methods to control for confounding. Limitations include the retrospective nature of the study and potential for unmeasured confounding. In summary, in a real-world cohort of older patients with DLBCL, use of prephase steroids was not associated either with longer TTNT/death, or with longer OS. However, it may be associated with maintenance of CIT dose intensity. This finding is worth exploring in future studies.

Factors Affecting Mortality in Elderly Hypertensive Hospitalized Patients with COVID-19: A Retrospective Study.

Corona Virus Disease 2019 (COVID-19) endangers the health and survival of the elderly. We tried to explore factors especially kidney function which affected mortality in elderly hypertensive patients with COVID-19. We conducted a retrospective research of 748 COVID-19 elderly patients (≥65 years old) at Zhejiang Hospital. This study compared demographic data, laboratory values, comorbidities, treatments, and clinical outcomes of hypertension and non-hypertension participants, and subgroup analysis of age and frailty was conducted in the hypertension population. Survival analysis was used to determine risk factors for death in elderly patients with COVID-19. Our study revealed that the elderly hypertensive patients with COVID-19 had higher blood urea nitrogen (BUN), serum uric acid (UA), serum creatinine (Scr), lower estimated glomerular filtration rate (eGFR), higher incidence of severity, admission to intensive care unit (ICU) and death, and longer in-hospital stay than non-hypertensive patients, which also occurred in the very elderly hypertensive patients compared with younger hypertensive patients and frail hypertensive patients compared with no-frail hypertensive patients. In addition, the prevalence of acute kidney injury (AKI) was higher in the oldest old hypertensive patients and frail hypertensive patients. Multivariate survival analysis indicated that the independent risk factors for death from COVID-19 were age ≥80 years, heart failure, antiviral therapy, calcium channel blocker (CCB) therapy, mechanical ventilation, AKI, and eGFR<60 mL/min per 1.73 m2. The results of the present study suggested that the elderly hypertensive patients with COVID-19 would have more serious kidney injury, more serious disease progression and higher mortality, which also occurred in very elderly and frailty subgroup. Kidney dysfunction was closely related to mortality in elderly patients with COVID-19.

Elevated ApoB/apoA-1 is Associated with in-Hospital Mortality in Elderly Patients with Acute Myocardial Infarction.

Apolipoprotein B/apolipoprotein A-1 (apoB/apoA-1) has been shown to be strongly associated with the risk of future cardiovascular disease, but the association between apoB/apoA-1 and the risk of in-hospital death in elderly patients with acute myocardial infarction(AMI) is inconclusive. To investigate the association between apoB/apoA-1 and the risk of in-hospital death in elderly patients with AMI. From December 2015 to December 2021, a total of 1495 elderly AMI patients (aged ≥ 60 years) with complete clinical history data were enrolled in the Second Hospital of Dalian Medical University. Outcome was defined as all-cause mortality during hospitalization. Multivariate logistic regression and restricted spline cubic (RCS) models were used to evaluate the association between apoB/apoA-1 and in-hospital mortality risk, respectively. Receiver operating characteristic(ROC) curves were used to evaluate the predictive value of apoB/apoA-1 for in-hospital mortality events. Discordance analysis was performed when apoB/apoA-1 and LDL-C/HDL-C were not in concordance. (1) A total of 128 patients (8.6%) died during hospitalization. Patients in the death group had higher apoB/apoA-1 than those in the non-death group, but lower apoA-1 levels than those in the non-death group, and the difference was statistically significant (P < 0.05); (2) Multivariate logistic regression analysis showed that apoB/apoA-1 was associated with the risk of in-hospital death in elderly AMI patients [Model 3 OR = 3.524 (1.622-7.659), P = 0.001]; (3) ROC curve analysis showed that apoB/apoA-1 (AUC = 0.572, P = 0.011) had some predictive value for the risk of in-hospital death in elderly AMI patients; (4) RCS models showed a linear dose-response relationship between apoB/apoA-1 and in-hospital death after adjusting for confounders (P for non-linearity = 0.762). ApoB/apoA-1 is associated with the risk of in-hospital death in elderly patients with AMI, and is superior to other blood lipid parameters and blood lipid ratio.

Factors Associated with COVID-19 Mortality in Elderly Patients in Intensive Care Unit

Objectives: Mortality rates in patients with COVID-19 infection admitted to the intensive care unit are influenced by various factors. In this study, we aimed to investigate the mortality rate and factors affecting mortality in patients admitted to the intensive care unit due to COVID-19 infection who had not been vaccinated. &#x0D; Methods: Our study was conducted retrospectively by scanning patients admitted to the intensive care unit of Izmir Bozyaka Education and Research Hospital of Health Sciences University from the beginning of 2020 to the end of 2022. Patients who were admitted to the intensive care unit were 65 years of age and older with COVID-19 infection. The patients' presenting complaints, degree of lung involvement, laboratory findings, and comorbidities were compared between patients who survived and those who passed away.&#x0D; Results: A total of 166 patients were evaluated in our study. Of these, 48 patients were discharged, while 118 patients experienced an excitus. The median age (IQR) for discharged patients was 71.5 (8), and for patients who experienced an excitus, it was 78 (15), which was found to be statistically significant (p

Effect of osteosarcopenia on the development of a second compression fracture and mortality in elderly patients after vertebroplasty.

This study aimed to investigate the effect of osteosarcopenia on second fracture development and mortality in patients aged above 60 years undergoing vertebroplasty because of osteoporotic vertebral compression fracture (OVCF). A retrospective evaluation was conducted on 104 patients treated by vertebroplasty because of OVF between 2016 and 2021. The L3 vertebra Hounsfield unit values and the psoas muscle index (PMI) values measured at the L3 vertebra level were obtained from the patients' medical data and computed tomography images. Using these measurements, the patients were divided into 3 groups: only osteoporosis (OO group), only sarcopenia (OS group), and osteosarcopenia (OSP group). Differences between the groups were evaluated regarding second OVCF development and mortality. The study included 104 patients, comprising 30 males and 74 females aged 60-92 years. The OS group included 10 patients, the OO group included 54 patients, and the OSP group consisted of 40 patients. A single vertebral fracture occurred in 72 patients, and 2 vertebral fractures occurred in 32 patients. The chi-square test, Mann-Whitney U-test, Kruskal-Wallis test, and Kaplan-Meier survival analysis results showed no statistically significant difference between the 3 groups for the risk of second vertebral fracture. Sarcopenia, either alone or in combination with osteoporosis, was seen to have a negative effect on the survival of patients who underwent vertebro- plasty following a vertebral fracture. This study has shown that osteosarcopenia did not increase the risk of developing a second vertebral fracture, but it increased mortality 2.8-fold for those who underwent vertebroplasty after vertebral fracture. Level III, Prognostic study.

Risk factors for early mortality in elderly patients with unstable isolated C2 odontoid fracture treated with halo-vest or surgery

The aim of this study was to compare in-hospital mortality of three procedures –halo-vest immobilization, anterior spinal fixation (ASF), and posterior spinal fixation (PSF)– in the treatment of elderly patients with isolated C2 odontoid fracture. We extracted data for elderly patients who were admitted with C2 odontoid fracture and treated with at least one of the three procedures (halo-vest immobilization, ASF, or PSF) during hospitalization. We conducted a generalized propensity score-based matching weight analysis to compare in-hospital mortality among the three procedures. We further investigated independent risk factors for in-hospital death. The study involved 891 patients (halo-vest, n = 463; ASF, n = 74; and PSF, n = 354) with a mean age of 78 years. In-hospital death occurred in 45 (5.1%) patients. Treatment type was not significantly associated with in-hospital mortality. Male sex (odds ratio 2.98; 95% confidence interval 1.32–6.73; p = 0.009) and a Charlson comorbidity index of ≥ 3 (odds ratio 9.18; 95% confidence interval 3.25–25.92; p < 0.001) were independent risk factors for in-hospital mortality. In conclusion, treatment type was not significantly associated with in-hospital mortality in elderly patients with isolated C2 odontoid fracture. Halo-vest immobilization can help to avoid adverse events in patients with C2 odontoid fracture who are considered less suitable for surgical treatment.

Development and validation of a nomogram for predicting pulmonary complications after video-assisted thoracoscopic surgery in elderly patients with lung cancer.

Postoperative pulmonary complications (PPCs) significantly increase the morbidity and mortality in elderly patients with lung cancer. Considering the adverse effects of PPCs, we aimed to derive and validate a nomogram to predict pulmonary complications after video-assisted thoracoscopic surgery in elderly patients with lung cancer and to assist surgeons in optimizing patient-centered treatment plans. The study enrolled 854 eligible elderly patients with lung cancer who underwent sub-lobectomy or lobectomy. A clinical prediction model for the probability of PPCs was developed using univariate and multivariate analyses. Furthermore, data from one center were used to derive the model, and data from another were used for external validation. The model's discriminatory capability, predictive accuracy, and clinical usefulness were assessed using the receiver operating characteristic (ROC) curve, calibration curve, and decision curve analysis, respectively. Among the eligible elderly patients with lung cancer, 214 (25.06%) developed pulmonary complications after video-assisted thoracoscopic surgery. Age, chronic obstructive pulmonary disease, surgical procedure, operative time, forced expiratory volume in one second, and the carbon monoxide diffusing capacity of the lung were independent predictors of PPCs and were included in the final model. The areas under the ROC curves (AUC) of the training and validation sets were 0.844 and 0.796, respectively. Ten-fold cross-validation was used to evaluate the generalizability of the predictive model, with an average AUC value of 0.839. The calibration curve showed good consistency between the observed and predicted probabilities. The proposed nomogram showed good net benefit with a relatively wide range of threshold probabilities. A nomogram for elderly patients with lung cancer can be derived using preoperative and intraoperative variables. Our model can also be accessed using the online web server https://pulmonary-disease-predictor.shinyapps.io/dynnomapp/. Combining both may help surgeons as a clinically easy-to-use tool for minimizing the prevalence of pulmonary complications after lung resection in elderly patients.

Factors Associated with 1-Year Mortality in Elderly Patients (Age ≥ 80 Years) with Cancer Undergoing Major Abdominal Surgery: A Retrospective Cohort Study.

The number of elderly patients undergoing major abdominal surgery is increasing, but the factors affecting their postoperative outcomes remain unclear. This study aimed to identify the factors associated with 1-year mortality among elderly patients (age ≥ 80 years) with cancer undergoing major abdominal surgery. This retrospective cohort study was conducted from March 2009 to December 2020. The study enrolled 378 patients 80 years old or older who underwent major abdominal surgery. The main outcome was 1-year mortality, and the factors associated with mortality were analyzed. Of the 378 patients, 92 died at 1 year (24.3%), whereas the 30-day mortality rate was 4% (n = 15). In the multivariate analysis, the factors independently associated with 1-year mortality were preoperative Eastern Cooperative Oncology Group (ECOG) performance status (PS) score higher than 1 (odds ratio [OR], 3.189; 95% confidence interval [CI], 1.595-6.377; p = 0.001), preoperative weight loss greater than 3 kg (OR, 2.145; 95% CI, 1.044-4.404; p = 0.038), use of an intraoperative vasopressor (OR, 3.090; 95% CI, 1.188-8.042; p = 0.021), and postoperative red blood cell units (OR, 1.212; 95% CI, 1.045-1.405; p = 0.011). Survival was associated with perioperative management according to an enhanced recovery after surgery (ERAS) protocol (OR, 0.370; 95% CI, 0.160-0.854; p = 0.006) and supramesocolic surgery (OR, 0.371; 95% CI, 0.158-0.871; p = 0.023). The study identified several factors associated with an encouraging 1-year mortality rate in this setting. These results highlight the need for identification of suitable targets to optimize pre-, intra-, and postoperative management in order to improve outcomes for this vulnerable population.

Predictors of mortality in elderly patients in emergency abdominal surgery: A retrospective single-center study

Background/Aim: Advancements in medical technologies and prolonged life expectancy have increased the number of surgical interventions for elderly patients. Despite this however, emergency surgical interventions remain associated with a high mortality rate. Managing an emergency abdominal surgery in elderly patients poses great challenges for both the surgeon and the anesthesiologist. However, knowing the risk factors that increase mortality may offer advantages to the clinician managing the treatment process. There are studies in the literature examining the mortality of emergency surgeries in elderly patients. However, there are very few studies that work with a specific patient group such as abdominal surgery and then analyze laboratory test results. Here, we aimed to identify the risk factors that can be used to predict mortality in elderly patients undergoing emergency abdominal surgery. Methods: The study was designed retrospectively in a single center; 100 patients over the age of 80 who underwent emergency abdominal surgery were included in the study. The patients were divided into two groups as survivor and non-survivor. Demographic, surgical, and anesthetic characteristics, laboratory tests, American Society of Anesthesiologists (ASA) physical status scores, postoperative intensive care needs, and treatments of the groups were compared using the chi-squared and Mann Whitney U-test. Determining factors were investigated with logistic regression analysis. Results: In multivariate analysis, ASA 3 and major surgery significantly increased mortality (P=0.041, P=0.011). Receiver operating characteristic (ROC) curve analysis showed that C-reactive protein with a cut-off value of &gt;84 mg/L had a sensitivity of 58.8% and a specificity of 71.2% (AUC=0.636, P=0.004), while lactate with a cut-off value of &gt;3.6 mmol/L had a sensitivity of 50% and a specificity of 95.5% in predicting mortality (AUC=0.776, P&lt;0.001). Conclusion: The magnitude of surgery and the ASA score were the best predictors of mortality in elderly patients undergoing emergency abdominal surgery.

Potential Role and Prognostic Value of Interleukin-15 for Mortality Among Elderly Patients with Sepsis.

To investigate the potential role and prognostic value of interleukin-15 (IL-15) in predicting 28-day mortality in elderly patients with sepsis. According to the Sepsis-3.0 diagnostic criteria for sepsis, elderly patients with sepsis who were admitted to the emergency department of the Shi jingshan branch of Beijing Chaoyang Hospital between October 2021 and June 2022 were enrolled in this retrospective cohort study. After observation for 28 days, patients were divided into a survival group and a nonsurvival group. Samples for laboratory tests, baseline characteristic data, and SOFA and Acute Physiology and Chronic Health Evaluation (APACHE II) scores were collected or recorded within 24 h after admission to the emergency department. Quantitative detection of IL-15 was performed with a Luminex assay. Logistic regression analysis and receiver operating characteristic curve (ROC) analysis were conducted for comparison. In total, 220 elderly patients with sepsis were enrolled, 69 of whom were in the survival group and 151 of whom were in the nonsurvival group at the 28-day interval. Systolic pressure, high-density lipoprotein (HDL), platelets (PLT) and albumin (ALB) were significantly higher in the survival group (P<0.05), while IL-15, SOFA, and APACHE II were significantly higher in the nonsurvival group (P<0.05). IL-15 was an independent risk factor associated with 28-day mortality (OR=1.842, 95% CI [1.323, 2.565]). The area under the receiver operating characteristic curve (AUROC) of IL-15 alone was 0.691 (95% CI [0.618, 0.764]), with a sensitivity of 46.67% and a specificity of 85.81%. The AUROC of the combined IL-15 and SOFA reached 0.880 (95% CI [0.672, 0.812]), for which the sensitivity and specificity were 80.95% and 85.08%, respectively. IL-15 possesses the prognostic value for predicting 28-day mortality in elderly patients with sepsis.

Inflammatory Index as a Predictor of Mortality in Elderly Patients With Intracapsular Femoral Neck Fracture.

A femoral neck fracture is a major cause of mortality in the elderly population, and intracapsular femoral neck fractures (ICFNFs) are commonly treated with hemiarthroplasty. The 30-day mortality rate for elderly hip fracture patients ranges from 1.0% to 6.5%, and one-year mortality increases significantly to 37.3%. Identifying predictors of mortality in these patients is crucial for better management. Inflammatory indices, such as neutrophil-to-lymphocyte ratio (NLR), systemic immune-inflammation index (SII), and monocyte-to-lymphocyte ratio (MLR), have gained popularity for assessing mortality risk in various diseases. Several studies have demonstrated the value of these indices in predicting mortality after hip fracture. The pan-inflammatory immune value (PIV), which combines hematological parameters, has been shown to predict mortality in cancer patients. However, its role in predicting mortality in ICFNF patients treated with hemiarthroplasty has yet to be explored. This study aimed to assess the association of PIV, SII, NLR, and MLR with 30-day and one-year mortality in ICFNF patients. We also investigated the impact of surgical delay time (≤24h, 24-48h, ≥48h) on these inflammatory indices and mortality. Data from 522 patients with ICFNF treated with hemiarthroplasty were retrospectively collected. We observed 30-day and one-year mortality rates of 5.24% and 21.2%, respectively. Age, gender, and American Society of Anesthesiologists (ASA) score were identified as significant predictors of mortality. Preoperative PIV, SII, NLR, and MLR were significant predictors in the evaluation of early mortality. However, postoperatively, only NLR on the third day (NLR3rd) demonstrated statistical significance. Stepwise logistic regression further confirmed NLR3rd as the most effective predictor for early mortality. For mortality occurring between 30 to 365 days, NLR3rd remained statistically significant, albeit with diminished sensitivity. No other inflammatory index demonstrated significant predictive power for mortality during this later period. Our findings suggest different inflammatory indices may have varying predictive abilities depending on the mortality period. We recommend considering NLR3rd as a valuable and reliable predictor for early mortality in ICFNF patients treated with hemiarthroplasty. Respiratory system disease and preoperative chronic obstructive pulmonary disease (COPD) were identified as risk factors for mortality in our study, in line with previous research. In conclusion, our study highlights the potential of specific inflammatory indexes, particularly NLR3rd, in predicting mortality in elderly patients with ICFNFs treated with hemiarthroplasty. Further research is needed to validate these findings and optimize risk assessment in orthopedic practice.

Risk Factors and Mortality of Elderly Patients with Hospital-Acquired Pneumonia of Carbapenem-Resistant Klebsiella pneumoniae Infection.

Hospital-acquired pneumonia (HAP) caused by carbapenem-resistant K. pneumoniae (CRKP), especially in elderly patients, results in high morbidity and mortality. Studies on risk factors, mortality, and antimicrobial susceptibility of CRKP pulmonary infection among elderly patients are lacking. A retrospective case-control study was conducted from January 2019 to December 2021. The elderly inpatients (≥65 years) who were diagnosed with HAP caused by K. pneumoniae were enrolled. Clinical data were collected. Univariate and multivariate logistic regression analyses were used to identify risk factors. Propensity score matching was used to minimize the effect of potential confounding variables. Kaplan-Meier analysis was used to compare survival. A total of 115 patients with CRKP infection and 78 patients with carbapenem-susceptible K. pneumoniae (CSKP) infection were recruited. There were four independent risk factors for CRKP infection: history of intensive care unit (ICU) stays from hospital admission to positive respiratory specimen culture for K. pneumoniae (odds ratio (OR)=2.530), Charlson comorbidity index score ≥3 (OR = 2.420), prior exposure to carbapenems (OR = 5.280), and prior K. pneumoniae infection or colonization in the preceding 3 years (OR = 18.529). The all-cause 30-day mortality was 22.3%, the mortality of CRKP and CSKP infection was 28.7% and 12.8%, respectively. Independent risk factors for mortality included: older age (OR = 1.107), immunocompromised patients (OR = 8.632), severe pneumonia (OR = 51.244), quick Sepsis-related Organ Failure Assessment (qSOFA) score ≥2 (OR = 6.187), exposure to tigecycline before infection (OR = 24.702), and prolonged ICU stay (OR = 0.987). Thirty-day mortality was significantly lower in patients receiving ceftazidime-avibactam (CAZ-AVI) containing regimens than patients receiving polymyxin B sulfate (PB) containing regimens (P = 0.048). qSOFA score had a good prognostic effect [area under receiver operating characteristic curve (AUROC) of 0.838]. Active screening of CRKP for the high-risk populations, especially elderly patients, is significant for early detection and successful management of CRKP infection.

Association between geriatric nutritional risk index and 28 days mortality in elderly patients with sepsis: a retrospective cohort study.

There is a significant controversy surrounding the impact of the geriatric nutritional risk index (GNRI) on mortality among elderly septic patients. This retrospective cohort study aimed to investigate the association between GNRI at admission and 28 days mortality in elderly septic patients. We retrospectively analyzed data collected from the MIMIC IV database between 2009 and 2019, which included 2,834 septic patients aged 65 years and above. The exposure variable was the GNRI, determined according to albumin levels, height, and weight. The primary outcome was 28 days mortality. We employed multivariable Cox regression analyses and Kaplan-Meier survival curves to examine the association between GNRI and 28 days mortality. We used restricted cubic splines to determine if there was a non-linear relationship between 28 days mortality and GNRI in elderly patients with sepsis and to examine the presence of a threshold saturation effect. In addition, interaction tests were conducted to identify subgroups that exhibited significant differences. A total of 2,834 elderly patients with sepsis participated in the study. Following adjustment, multivariable Cox regression analyses demonstrated that the GNRI was related to 28 days mortality (HR = 0.97, p < 0.001, 95% CI: 0.97-0.98). An L-shaped connection between GNRI and 28 days mortality was discovered via restricted cubic spline analysis, with an inflection point of 98.1. On the left side of the inflection point, GNRI levels were significantly negatively linked with 28 days mortality (HR = 0.967, 95% CI: 0.959-0.974; p < 0.001), and on the right side, there was no significant correlation (HR = 1.043, 95% CI: 0.984-1.106; p = 0.1549). In this analysis of data from a large cohort of elderly septic patients, GNRI scores on admission were correlated with a 28 days risk of death from sepsis in the elderly suggesting that GNRI scores could serve as a valuable indicator for evaluating mortality rates among elderly septic patients in the intensive care unit (ICU).

Thrombin Generation Is Associated with Venous Thromboembolism Recurrence, but Not with Major Bleeding and Death in the Elderly: A Prospective Multicenter Cohort Study.

It is currently unknown whether thrombin generation is associated with venous thromboembolism (VTE) recurrence, major bleeding, or mortality in the elderly. Therefore, our aim was to prospectively study the association between thrombin generation and VTE recurrence, major bleeding, and mortality in elderly patients with acute VTE. Consecutive patients aged ≥65 years with acute VTE were followed for 2 years, starting from 1 year after the index VTE. Primary outcomes were VTE recurrence, major bleeding, and mortality. Thrombin generation was assessed in 551 patients 1 year after the index VTE. At this time, 59% of the patients were still anticoagulated. Thrombin generation was discriminatory for VTE recurrence, but not for major bleeding and mortality in non-anticoagulated patients. Moreover, peak ratio (adjusted subhazard ratio 4.09, 95% CI, 1.12-14.92) and normalized peak ratio (adjusted subhazard ratio 2.18, 95% CI, 1.28-3.73) in the presence/absence of thrombomodulin were associated with VTE recurrence, but not with major bleeding and mortality after adjustment for potential confounding factors. In elderly patients, thrombin generation was associated with VTE recurrence, but not with major bleeding and/or mortality. Therefore, our study suggests the potential usefulness of thrombin generation measurement after anticoagulation completion for VTE to help identify among elderly patients those at higher risk of VTE recurrence.

A Novel Frailty Score Based on Laboratory Parameters (FIMS Score) for the Management of Older Patients with Severe Aortic Stenosis.

This study aimed to develop a novel score based on common laboratory parameters able to identify frail and sarcopenic patients as well as predict mortality in elderly patients with severe aortic stenosis (AS) for tailored clinical decision-making. A total of 109 patients (83 ± 5 years; females, 68%) with AS underwent a multidisciplinary pre-operative assessment and finalized a "frailty-based management" for the AS interventional treatment. Laboratory parameters of statistically significant differences between sarcopenic and non-sarcopenic individuals were tested in the structural equation model (SEM) to build a Frailty Inflammation Malnutrition and Sarcopenia score (FIMS score). Mortality at 20 months of follow-up was considered an outcome. FIMS score, in particular, the cut-off value ≥ 1.28 was able to identify "frail" and "early frail" patients and predict mortality with a sensitivity of 83.3% and 82.6%, respectively (p = 0.001) and was an independent determinant associated with a higher risk of mortality (HR 5.382; p-value = 0.002). The FIMS score, easily achievable and usable in clinical practice, was able to identify frail and sarcopenic patients as well as predict their adverse clinical outcomes. This score could provide appropriate guidance during decision-making regarding elderly patients with severe AS.

Effect of statin treatment on mortality in elderly patients with type 2 diabetes mellitus patients: a retrospective cohort study

BackgroundThe effects of statins on the reduction of mortality in individuals aged 75 years or older remain controversial. We conducted this study to investigate whether there is an association between statin therapy and mortality in patients with type 2 diabetes mellitus (T2DM) who are over the age of 75 years.MethodsThe present study used data from the Staged Diabetes Targeting Management Study, which began in 2005. A total of 518 T2DM patients older than 75 years were included. Cox regression analyses were used to evaluate the association between statins and specific causes of death in patients with T2DM.ResultsAfter a follow-up period of 6.09 years (interquartile range 3.94–8.81 years), 111 out of 518 patients died. The results of Cox regression analyses showed that there was no significant association between statin use and all-cause mortality (HR 0.75; 95% CI 0.47, 1.19) after adjustment for all potential confounders. Subgroup analysis indicated that statins had no association with the risk of all-cause mortality or deaths caused by ischemic cardiovascular diseases in T2DM patients with or without coronary heart disease.ConclusionsOur study found no significant association between all-cause mortality and statin use in T2DM patients over the age of 75 years. More evidence is needed to support the use of statins in the elderly T2DM patients.
