A novel scoring system proposal to guide surgical treatment indications for high grade gliomas in elderly patients: DAK-75.

High-grade gliomas are the most prevalent neurooncological desease in adults, their incidence increases with age, peaking in the seventh decade. This paper aims to address how to select patients for surgical resection by identifying pre-surgical predictors of 12-month mortality in newly diagnosed HGG patients aged ≥ 75years. A prognostic score will be proposed to guide surgical decisions based on expected survival. Retrospective observational single-center cohort study was carried out at the "Città della Salute e della Scienza-Molinette" University Hospital in Turin, Italy. All consecutive patients aged ≥ 75years newly diagnosed with HGG were included, regardless of whether they underwent surgical resection. Clinical, radiological, histological and molecular data were collected.Variables potentially available at the time of diagnosis were considered to develop a multivariable logistic regression predictive model, with 12-months overall survival as the dependent variable. 102 patients aged 75years or older received a new diagnosis of high-grade glioma, of whom 68 underwent surgical resection. Patients undergoing surgery were slightly younger (76.9 vs 79.0years, p = 0.007) and had better performance status (median KPS 80 vs 70). Most tumors undergoing surgery were localized in cortical or subcortical non-motor areas (p < 0.001) and less frequently deep-seated (p = 0.023) or multifocal (p < 0.001). A predictive model, the DAK-75 score, was developed: the AUROC of the final model was 0.822 (95% CI 0.741-0.902). The score includes clinical presentation, tumor location, and KPS, ranging from 0 to 20, categorizing risk scores into low-risk and high-risk groups (< or > 8). Higher scores corresponded to fewer surgical patients and higher one-year mortality rates (92.2% vs 47.1%, p < 0.001). DAK-75 score may represent a valuable tool in the decision-making process for neurosurgical intervention in elderly patients diagnosed with HGG. Further studies are needed to externally and prospectively validate the scoring system.

Can tip-apex distance and calcar reference tip-apex distance predict lag screw cut-out in elderly patients with trochanteric femoral fractures treated with gamma3 nails

Background: The most common complication of cephalomedullary nail fixation for femoral fractures is lag screw cut-out. The significance of the tip-apex distance (TAD) in predicting lag screw cut-out is still debated. There has been no study conducted on the calcar reference tip-apex distance (CalTAD) regarding its impact on lag screw cut-out. To compare the average TAD and CalTAD between groups with and without lag screw cut-out and to determine the TAD and CalTAD values associated with the highest risk of lag screw cut-out. Methods: This was a prognostic prediction study utilizing a retrospective cohort of 756 patients with trochanteric femoral fractures treated with Gamma3 nails. This study compared the differences in TAD and CalTAD values between the two groups. Results: The group without lag screw cut-out had lower TAD and CalTAD values compared to the group with lag screw cut-out (TAD; 20.3±5.3 mm vs. 22.1±5.7 mm; p=0.044); (CalTAD 22.3±4.4 mm vs. 25.2±5.3 mm; p&lt;0.001). The cutoff points of TAD &gt;23 mm and CalTAD &gt;25 mm were associated with the highest risk of lag screw cut-out (TAD: OR, 2.91; 95% CI, 1.47-5.77; p=0.002); (CalTAD: OR, 3.43; 95% CI, 1.73-6.80; p&lt;0.001). Conclusions: The lag screw cut-out group had higher TAD and CalTAD values. TAD values greater than 23 mm and CalTAD values greater than 25 mm were associated with the highest risk of lag screw cut-out.

Public Health Benefits of Applying Evidence-Based Best Practices in Managing Patients Hospitalized for COVID-19.

As COVID-19-related mortality remains a concern, optimal management of patients hospitalized for COVID-19 continues to evolve. We developed a population model based on real-world evidence to quantify the clinical impact of increased utilization of remdesivir, the effectiveness of which has been well established in hospitalized patients with COVID-19. The PINC AI healthcare database records for patients hospitalized for COVID-19 from January to December 2023 were stratified by those treated with or without remdesivir ("RDV" and "No RDV") and by supplemental oxygen requirements: no supplemental oxygen charges (NSOc), low-flow oxygen (LFO), and high-flow oxygen/non-invasive ventilation (HFO/NIV). Key vulnerable subgroups such as elderly and immunocompromised patients were also evaluated. The model applied previously published hazard ratios (HRs) to 28-day in-hospital mortality incidence to determine the number of potential lives saved if additional "No RDV" patients had been treated with remdesivir upon hospital admission. Of 84,810 hospitalizations for COVID-19 in 2023, 13,233 "No RDV" patients were similar in terms of characteristics and clinical presentation to the "RDV" patients. The model predicted that initiation of remdesivir in these patients could have saved 231 lives. Projected nationally, this translates to >800 potential lives saved (95% CI: 469-1,126). Eighty-nine percent of potential lives saved were elderly and 19% were immunocompromised individuals. Seventy-one percent were among NSOc or LFO patients. This public health model underscores the value of initiating remdesivir upon admission in patients hospitalized for COVID-19, in accordance with evidence-based best practices, to minimize lives lost due to SARS-CoV-2 infection.

Comparison of Differences in Kinetics of Elderly Women at Risk of Falling during Lumbar Stabilization Exercise per Obstacle Height

This study was performed to identify the kinetic and kinematic effects of the lumbar stabilization exercise on obstacle gait(5.2cm,15.2cm) among elderly women at risk of falls. The study subjects were 32 women aged 65 and over with a risk of falls identified by the Tinetti test. They were randomly allocated into 2 groups: the experimental group and the control group, and the lumbar stabilization exercise program was given to the experimental group for 12 weeks. The chi-square test and t-test were used to test homogeneity and compare baseline results of kinetic measurements on obstacle gait between the experimental and control groups. To identify the effects of the lumbar stabilization exercise program among study subjects, repeated measures of analysis of variance (ANOVA) were performed. Regarding kinetic variables, the knee joint angle of the propulsion foot significantly increased when overcoming a 5.2cm obstacle. When overcoming a 15.2cm obstacle, the obstacle overcoming speed and the knee joint angles of the support and propulsion feet significantly increased. However, the shortest vertical distance between the support and propulsion feet was reduced considerably. Our findings suggest that lumbar stabilization exercises could be a promising therapeutic exercise method for fall prevention and management in elderly women at risk of falling, providing reassurance about the effectiveness of our study's findings and the potential benefits for the elderly and other patients requiring trunk stability.

Alterations in expression of TLR2 and TLR4 during successful and pathological aging

The generally accepted theory of aging is the theory of inflammaging. The leading role in its development is played by the mechanisms of innate immunity. Key receptors of innate immunity are TLRs. The patterns of age-related changes in the functioning of the TLR system remain the subject of study. The purpose of the work is to study the expression of TLR2 and TLR4 receptors in peripheral blood cells of centenarians and elderly people at the level of genes and surface molecules. The study analyzed the expression of genes and molecules TLR2 and TLR4 in young donors (n = 50), elderly people (n = 50) and centenarians (n = 100). Analysis of TLR2 and TLR4 gene expression was carried out using RT-PCR. Determination of surface expression of TLR2 and TLR4 was carried out using flow cytofluorimetry. This study is the first to analyze the age-related dynamics of expression of genes and molecules TLR2 and TLR4. It was revealed that in groups of elderly patients and long-livers, TLR2 expression is increased both at the gene and on the cell surface, compared to young donors. In contrast, TLR4 expression decreased with age. Studied groups of patients were divided depending on the aging phenotype into two subgroups: successful and pathological aging. In elderly individuals, TLR2 is increased in both phenotypes, while TLR4 is decreased in the pathological aging. In the group of centenarians with a pathological aging, a decrease in both TLR2 and TLR4 is observed, compared with young. In long-livers with successful aging, an increase in TLR2 expression was observed at the gene and protein level and TLR4 expression was comparable to the group of young individuals. Identified changes in the expression of TLR2 and TLR4, observed in different age groups, can be considered as markers of various aging phenotypes.

Azacitidine in combination with shortened venetoclax treatment cycles in patients with acute myeloid leukemia.

The combination of venetoclax with hypomethylating agents is currently the standard of care for elderly patients with acute myeloid leukemia (AML) ineligible for intensive chemotherapy. Despite its favorable efficacy, clinical use is often associated with post-remission cytopenia, frequently necessitating treatment delays and dose modifications. This study aims to evaluate the efficacy and safety of shortened venetoclax treatment durations. A multicenter analysis was conducted involving 20 adult AML patients receiving venetoclax (7 or 14 days with 9 and 11 patients, respectively) combined with 5-azacitidine (5-7 days) between 2021 and 2024. The cohort included patients from four German academic centers all treated in first line. Outcome measures included bone marrow response, transfusion dependence, overall survival (OS) and progression-free survival (PFS). Median age was 73.5 years, with 70% of patients having secondary AML. Adverse molecular risk was observed in 75% of patients. The overall response rate (ORR) was 100%, with a composite complete remission rate of 78%. No significant differences in response rates were observed between the 7-day and 14-day venetoclax regimens. Median OS for the cohort was 15 months. Infection-related complications were observed in 55% of patients, with severe sepsis in 20% of cases. In this cohort, shortened venetoclax regimens demonstrated efficacy comparable to standard treatment protocols, with a potential reduction in hematologic toxicity. These findings support the individualization of treatment regimens to optimize clinical outcomes while potentially minimizing adverse effects.

The efficacy of preemptive multimodal analgesia in elderly patients undergoing laparoscopic colorectal surgery: a randomized controlled trial

Objective To evaluate the effectiveness of preemptive multimodal analgesiain elderly patients undergoing laparoscopic colorectal surgery. Methods A prospective randomized controlled study was conducted in the Department of Gastrointestinal Surgery of the Second Hospital of Hebei Medical University from January 2022 to December 2022. A total of 133 patients were included according to the criteria and randomly divided into preemptive analgesia (PRA) group (test group, 67patients) and postoperative analgesia (POA) group (control group, 66patients). Results The Visual Analog Scale (VAS)scores of PRA group 24 h, 48 h, and 72 h after operation were lower than those of POA group, and the difference was statistically significant, P < 0.001.The incidences of postoperative gastrointestinal dysfunction (POGD) and postoperative delirium (POD)in PRA group were 13.43% and 8.98%, respectively, which were significantly lower than those in POA group (31.82% and 24.24%), P < 0.05. The levels of IL-6 and IL-10 in PRA group after the operation were 17.54 ± 2.13 ng/L and 15.57 ± 1.71 ng/L respectively, which were lower than those in POA group (25.45 ± 2.95 ng/L and 23.45 ± 1.88 ng/L), P < 0.05. The level of acetylcholinesterase(AchE) was 56.34 ± 5.62 nmol/L in the POA group, which was significantly higher than that in the POA group (49.59 ± 5.52 nmol/L), P < 0.001. Conclusion Preemptive multimodal analgesia can reduce the incidence of POGD and POD in elderly patients undergoing laparoscopic gastrocolic surgery, improve the recovery process of postoperative gastrointestinal function, increase the concentrations of propionic acid and butyric acid in short chain fatty acids (SCFAs) and the number of beneficial intestinal bacteria.

Impact of atrial high-rate episodes on new onset of atrial fibrillation and all-cause mortality in elderly patients over 90 years old with dual-chamber pacemaker implantation

Objective: To investigate the impacts of atrial high-rate episodes (AHRE) on the risks of new onset of atrial fibrillation and all-cause mortality in elderly patients over 90 years old after cardiac dual-chamber pacemaker implantation. Methods: This study was a retrospective study. Patients aged 90 years and above who were implanted with cardiac dual-chamber pacemakers and followed up in the People's Liberation Army General Hospital from January 2017 to June 2022 were enrolled and divided into AHRE≥6 h group and AHRE<6 h group according to the onset time of AHRE. The primary endpoint was new onset of atrial fibrillation, and the secondary endpoints were all-cause mortality and cardiovascular mortality. Kaplan-Meier survival curve was poltted, and log-rank test was used to compare the differences in the incidence of new onset of atrial fibrillation, all-cause death and cardiovascular death between AHRE≥6 h and AHRE<6 h groups. Multivariate Cox survival analysis was used to investigate the factors affecting new onset of atrial fibrillation, all-cause death and cardiovascular death in elderly patients aged 90 years and above with dual-chamber pacemaker implantation. Results: A total of 169 patients were enrolled, aged (93.95±3.28) years, including 18 females (11%). The median follow-up time was 28.9 months. There were 87 and 82 patients in AHRE≥6 h group and AHRE<6 h group, respectively. Kaplan-Meier survival curve analysis showed that the incidence of new onset of atrial fibrillation (log-rank P<0.001), all-cause death (log-rank P=0.004) and cardiovascular death (log-rank P=0.026) in AHRE≥6 h group was significantly higher than that in AHRE<6 h group.After adjusting for traditional risk factors, multivariate Cox survival analysis showed that AHRE≥6 h was an independent risk factor for new onset of atrial fibrillation (HR=4.046, 95%CI 2.402-6.814, P<0.001) and all-cause mortality (HR=1.668, 95%CI 1.119-2.487, P=0.012) in elderly patients over 90 years old with cardiac dual-chamber pacemaker implantation. However, AHRE≥6 h had no effect on cardiovascular mortality (P>0.05). Anemia (HR=3.098, 95%CI 1.342-7.153, P=0.008) and heart failure with reduced ejection fraction (HR=3.028, 95%CI 1.181-7.763, P=0.021) were both independently associated with cardiovascular mortality. Conclusions: AHRE is common in cardiac dual-chamber pacemakers recipients aged 90 years and above, and AHRE≥6 h can be used as a predictor of new onset of atrial fibrillation or all-cause mortality in these patients.

Enhanced recovery after surgery (ERAS) improves outcomes in elderly patients undergoing short-level lumbar fusion surgery: a retrospective study of 333 cases

BackgroundDegenerative lumbar disease significantly impairs the quality of life in elderly individuals, with short-segment lumbar degenerative disease being particularly prevalent. When conservative treatment proves ineffective, surgical intervention becomes the optimal choice for managing lumbar disease. The implementation of Enhanced Recovery After Surgery (ERAS) in spinal surgery has been progressively refined, leading to greater patient benefits. However, age and the associated decline in physiological function remain critical factors influencing surgical decision-making. Currently, there is a paucity of research focused on elderly patients undergoing lumbar fusion surgery to substantiate that advanced age does not diminish the benefits derived from ERAS in this demographic.MethodsThis is a retrospective cohort study of prospectively collected data. Patients who underwent short-segment (1 or 2 segments) transforaminal lumbar interbody fusion (TLIF) under the care of the same surgical team at our institution were recruited, and divided into no-ERAS-elder, ERAS-elder, and ERAS-younger groups. Subsequently, time to physiological function recovery and other outcomes were compared.ResultsThe outcomes of the ERAS-elder group (n = 113) and the no-ERAS-elder group (n = 120) were compared. The overall physiological function recovery was significantly faster (6.71 ± 2.6 days vs. 8.6 ± 2.67 days, p = 0.01) in the ERAS-elder group. Next, the outcomes of the ERAS-elder group (n = 113) were compared with those of the ERAS-younger group (n = 100), and no significant difference in total physiological function recovery was found between the two groups (6.71 ± 2.6 days vs. 6.14 ± 1.63 days, p = 0.252).ConclusionsThis study shows that the implementation of the ERAS program can effectively shorten the recovery time of physiological function in elderly patients after short-segment lumbar surgery, reduce the incidence of some complications, alleviate pain, and significantly shorten the length of hospital stay. ERAS enables elderly patients to achieve outcomes comparable to those of younger patients.

Nutritional status and triglyceride-glucose index influence delirium in elderly heart failure patients

Malnutrition and insulin resistance are linked to complications like delirium, yet their impact on elderly heart failure patients remains underexplored. This study investigates how nutritional status and the triglyceride-glucose (TyG) index influence delirium in this population. We conducted a retrospective study involving patients aged 75 and older with decompensated heart failure. Delirium was assessed using the Confusion Assessment Method (CAM), and nutritional status was evaluated with the Mini Nutritional Assessment Scale-Short Form (MNA-SF). The TyG index was calculated as: TyG index = ln [triglycerides (mg/dL) × fasting glucose (mg/dL) / 2]. The study included 412 patients (mean age 84.30 ± 5.16 years; 56.31% male), with 24.03% experiencing delirium during hospitalization. After adjusting for confounders, a higher TyG index was significantly associated with increased delirium risk (OR = 1.549, 95% CI: 1.102–2.178, P = 0.012), while a higher MNA-SF score correlated with reduced risk (OR = 0.793, 95% CI: 0.662–0.949, P = 0.011). Kaplan-Meier analysis showed significant differences in cumulative survival based on nutritional status and TyG index (Log-Rank test: χ²= 65.604, P < 0.001). Mediation analysis indicated that nutritional status partially mediated the relationship between the TyG index and delirium, and vice versa. Malnutrition and elevated TyG index levels increase delirium risk in elderly heart failure patients, underscoring the need for effective nutritional management and metabolic regulation.

Diabetic Striatopathy: A Case Report of Two Distinct Presentations in Elderly Patients

Diabetic Striatopathy: A Case Report of Two Distinct Presentations in Elderly Patients

When hypoxemia does not respond to oxygen therapy: a case of platypnea-orthodeoxia syndrome.

Platypnea-orthodeoxia syndrome (POS) is a rare clinical entity characterized by the onset of dyspnea and hypoxemia that normally manifests in the upright position, improving with recumbency. POS is generally caused by both anatomical and functional defects that lead to a right-to-left shunt. Herein, we present an illustrative case of POS in an elderly patient admitted for severe hypoxemia, in which a massive right-to-left shunt through a patent foramen ovale facilitated by an anatomic disturbance was found. Percutaneous closure of the defect was performed, thus correcting the POS.

Efficacy of atorvastatin on renal function in patients with contrast-induced nephropathy after percutaneous coronary intervention

BackgroundAt present, the clinical methods for preventing and treating contrast-induced nephropathy (CIN) are limited, and statins can play a better role during this process. So, we aimed to assess the atorvastatin on renal function in nephropathy patients after percutaneous coronary intervention (PCI).MethodsIn this work, 100 elderly patients with coronary heart disease (CHD) were selected into an experimental group (Exp group, 50 cases, 40 mg/d po atorvastatin) and a control group (Ctrl group, 50 cases, 10 mg/d po atorvastatin). The renal function indicators, blood routine indicators, and the incidence of adverse reactions (ARs) were compared between patients in Exp and Ctrl groups.ResultsAfter surgery, the levels of serum creatinine (SCr), blood urea nitrogen (BUN), cystatin C (CysC), high-sensitivity C-reactive protein (hs-CRP), and interleukin (IL6) in patients in the Exp group were much lower, and the levels of estimated glomerular filtration rate (eGFR) and superoxide dismutase (SOD) were higher (all P < 0.05). Meanwhile, the incidences of ARs during hospitalization between patients in the Exp and Ctrl groups were all 8%, showing no observable difference (P > 0.05). Compared with conventional doses of atorvastatin, high-dose atorvastatin can effectively prevent renal function damage in patients with CIN, decrease the inflammation and oxidative stress in patients, and will not increase the risk of ARs during hospitalization.ConclusionTaken together, high-dose atorvastatin can be applied in treating patients with CHD after PCI due to its excellent efficacy and high safety.

Exploring the Effectiveness of Technology-Assisted Interventions for Promoting Independence in Elderly Patients: A Systematic Review

Background: The aging global population presents significant challenges for healthcare systems. Technology-assisted interventions have emerged as promising tools to enhance independence and well-being among elderly individuals. Objective: The aim of this study was to evaluate the effectiveness of technology-assisted interventions in promoting independence among elderly patients and identify key barriers and facilitators to their implementation. Methods: A systematic review was conducted following PRISMA guidelines. Searches were performed in PubMed, IEEE Xplore, ACM Digital Library, Cochrane Library, and Scopus. Studies evaluating technology-assisted interventions for promoting independence in elderly patients were included. Data were synthesized through narrative and thematic analysis. Results: Fourteen studies met inclusion criteria. Technology-assisted interventions demonstrated positive impacts on physical and cognitive functioning, health management, quality of life, and technological engagement among elderly patients. Improvements were observed in areas such as mobility, chronic disease management, mental health, and daily living activities. High usability and adherence rates were reported for well-designed interventions. However, challenges in user-centered design, personalization, and integration with existing healthcare systems were identified. Conclusions: Technology-assisted interventions show promise in promoting independence among elderly patients. Future research should focus on addressing identified challenges and conducting larger, long-term studies to confirm effectiveness and sustainability.

Short- and long-term outcomes of laparoscopic right hemicolectomy with D3 resection for right colon cancer in elderly patients.

Laparoscopic right hemicolectomy (RHC) with D3 resection, similar to complete mesocolic excision, is an oncologically satisfying procedure; however, it remains controversial in elderly patients. There are no reports of the procedure for tumors fed by middle colic vessels because it is a difficult procedure. We evaluated the feasibility and oncological outcomes of the procedure in elderly patients. We retrospectively evaluated 336 consecutive patients undergoing laparoscopic right hemicolectomy with D3 resection for Stage I-III ascending and transverse colon cancer between 2010 and 2021. Patients were divided into the EP (age ≥ 75 years) and nEP (age < 75 years) groups, and short- and long-term outcomes were analyzed using propensity score matching. The median follow-up period was 60.7 months. After matching, we enrolled 129 patients. The surgery time, estimated blood loss, postoperative complication rate, number of harvested lymph nodes, and recurrence rate did not differ significantly between the groups; however, the adjuvant chemotherapy rate was significantly lower in the EP group. The EP group had significantly shorter overall survival (OS) (p < 0.01) than the nEP group; however, the cancer-specific (p = 0.15) and recurrence-free (p = 0.36) survivals did not differ significantly from those in the nEP group. In multivariate analyses, age ≥ 75 years, ASA ≥ 3, and pT4 were independent prognostic factors for OS (p = 0.02, < 0.01, < 0.01, respectively); however, only pT4 was an independent prognostic factor for CSS and RFS (p < 0.01 for both). This procedure offers safe, feasible, and satisfactory oncological outcomes for elderly patients.

Minimally Invasive Mitral Valve Surgery in Elderly Patients: Results from a Multicenter Study

Background: Minimally invasive mitral valve surgery (MIMVS) has been increasingly adopted worldwide as an alternative to conventional sternotomy, especially for young patients. The remarkable results gained by MIMVS have encouraged its application in more complex and fragile patients, such as the elderly, though results in this subgroup remain controversial. It is the aim of this study to assess the postoperative outcomes of patients older than 75 years old undergoing MIMVS, and to compare these results to those of younger patients. Methods: The data of all patients undergoing MIMVS between 2015 and 2022 were retrospectively collected at seven high-volume cardiac surgery centers. Patients were divided into two age-based groups: the young (&lt;65 years old) and the elderly (&gt;75 years old). A propensity score (PS) matching analysis obtained two comparable groups. Postoperative outcomes were assessed in both the unmatched and PS-matched populations. Results: Out of 1113 patients undergoing MIMVS, 524 were young and 279 were elderly. Elderly patients were more commonly affected by multiple comorbidities, with a higher EuroSCORE II (4.6 ± 5.5% vs. 1.6 ± 3.3%, p &lt; 0.001). There was no difference in postoperative mortality, though the elderly had a greater incidence of postoperative complications, such as re-exploration for bleeding, stroke, reintubation, and a need for hemodialysis and blood transfusions. After PS matching, 119 pairs of young and elderly patients with similar risk profiles (EuroSCORE II 2.5 ± 4.7% vs. 2.7 ± 3.2%, p = 0.7) were compared, and no differences in all postoperative outcomes were found. Conclusions: Adequately selected elderly patients can report hospital outcomes similar to young patients after MIMVS.

Improvement in pain by using lidocaine combined with esketamine in elderly patients receiving local anaesthesia for percutaneous kyphoplasty: a randomized controlled study

BackgroundElderly patients often experience severe pain during percutaneous kyphoplasty under local anaesthesia. The aim of this work was to evaluate the effect of lidocaine combined with esketamine on pain improvement in elderly patients receiving local anaesthesia via percutaneous kyphoplasty.MethodsThis prospective, randomized comparative trial was conducted on 66 elderly patients, aged 60–80 years, with an American Society of Anaesthesiologists (ASA) grade of I-III, I‒III and a BMI of 18.5–25 kg/m2, who underwent single-level lumbar percutaneous kyphoplasty under local anaesthesia. Patients were divided into two equal groups (33 per group). Group LE received 200 mg of 1% lidocaine and 25 mg of esketamine (total volume of 20 ml), and Group L received 200 mg of 1% lidocaine (total volume of 20 ml). Patient characteristics, surgery, VAS scores, MAP, HR, MOAA/S scores, patient satisfaction and related adverse reactions were compared for the groups. The VAS scores during and after surgery were considered the primary outcome.ResultsThere were statistically significant differences in the VAS score between the two groups at the following time points: channel establishment by the puncture needle, balloon dilation, bone cement injection and postoperative period (P < 0.05). The VAS score decreased in the LE group, but the MAP and HR were more stable, and the difference was statistically significant (P < 0.05). The difference in the MOAA/S score between the two groups was statistically significant (P < 0.05), and the MOAA/S score in the LE group decreased. The patient satisfaction level in the LE group was 100% and 48.48% in the L group (P < 0.05). There were no related complications or adverse reactions in either group.ConclusionThe application of lidocaine combined with esketamine in local episcopal percutaneous vertebral kyphoplasty in elderly patients not only provides an effective analgesic effect but also improves surgical safety and patient comfort, which has important clinical value in promoting the optimization of surgical anaesthesia management in elderly patients.Trial registrationThe study was registered at Chictr.org.cn with the number ChiCTR2400083466 on 06/12/2023.

Impact of Obesity on Gleason Score- Elderly and Very Elderly Patients with Prostate Cancer Indicated for Radical Radiotherapy

Introduction: Prostate cancer is an important public health concern in Brazil, especially among older men, with a significant mortality rate. In addition to advanced age, obesity emerges as a relevant risk factor, associated with a worse prognosis of the disease. Objective: To investigate the relationship between body mass index (BMI) and Gleason score in older and very older patients with prostate cancer indicated for radiotherapy treatment. Methods: Prospective, descriptive, and longitudinal study with 258 patients with prostate cancer, evaluating age, initial PSA, BMI, race, and Gleason Score. Result: Findings revealed an association between a higher BMI and a more aggressive degree of disease, as indicated by higher Gleason scores. Conclusion: Overweight and obese patients have a higher and more evident Gleason score in older patients compared to the very older, being more notable in the older. This study is one of the few studies to examine the link between BMI and poor prognosis in prostate cancer patients
