Prospective Randomized Controlled Trial Between Fibula Intramedullary Nail Fixation vs Open Reduction and Internal Fixation for the Surgical Management of Unstable Ankle Fractures

Category: Ankle; Trauma Introduction/Purpose: The fundamental concept of open reduction and internal fixation (ORIF) of unstable ankle fractures was anatomical reduction and firm fixation that allow early mobilization and rehabilitation. On the other hand, ORIF of ankle fractures is associated with complications including wound dehiscence, necrosis and infection, prominent hardware and failure. Closed reduction and intramedullary fixation (CRIF) using fibula nail was emerged as additional surgical option for unstable ankle fractures especially in elderly and medical high-risk patients. We hypothesized that fibula nailing for unstable ankle fractures would have similar functional outcomes to standard ORIF. The purpose of this study is to perform a prospective randomized study to compare clinical outcomes, bone union, and postoperative complications between ORIF and CRIF using fibula nail. Methods: A total of 59 patients (32 men, 27 women) with the mean age of 50.2 years were prospectively randomized to undergo standard ORIF or fibular nailing for unstable ankle fractures: those who underwent ORIF (31 patients 14 men, 17 women) and those who underwent CRIF using fibula nail (29 patients; 18 men and 11women). Exclusion criteria of fracture characteristics were open fracture and highly comminuted fibula fractures. Functional scoring including VAS, AOFAS and FAOS were evaluated at minimum postoperative 2 years follow up. In addition, union period, reduction status of fracture and ankle mortise at postoperative CT scan, complications including wound problem and posttraumatic arthritis were evaluated. Results: The VAS, AOFAS, and all FAOS subscales were not significantly different between two group at 2 years postoperatively (all, p>0.05). Significantly fewer infections and wound complication occurred in the fibula nail group. (p < 0.05; ORIF group (12.9%), fibula nail group (0%)). Postoperative at fracture site of fibula was high in fibula nail group (p < 0.05; ORIF group (0%), fibula nail group (13.7%)), but there were no significant differences in the status of mortise and the rate of posttraumatic arthritis (all, p>0.05). Conclusion: We concluded that the fibula nail allows acceptable reduction and secure fixation of unstable ankle fracture, with low soft tissue complication rate than ORIF. Considering the property closed reduction, the fibula nail would be an excellent treatment option for patients with unstable ankle fractures when indications is well selected

Clinical Outcomes in Elderly Atrial Fibrillation Patients at Increased Bleeding Risk Treated with Very-Low-Dose versus Regular-Dose Non-Vitamin K Antagonist Oral Anticoagulants: a Nationwide Cohort Study.

The ELDERCARE-AF trial showed that edoxaban at a very-low-dosage (VLD) of 15mg/day was more effective than a placebo at preventing stroke/systemic embolism without significantly increasing the risk of serious bleeding. We aimed to compare the effectiveness and safety for VLD non-vitamin K antagonist oral anticoagulants (NOACs) (edoxaban 15mg once daily, dabigatran 110 or 150 once daily, apixaban 2.5mg once daily, or rivaroxaban 10mg (without the diagnosis of chronic kidney disease) or less than 10mg once daily) versus regular-dosage (RD) NOACs (edoxaban 60/30mg once daily or other labeling-dosage NOACs) among a real-world cohort of elderly AF population similar to the ELDERCARE-AF cohort. In this nationwide retrospective cohort study from Taiwan National Health Insurance Research Database (NHIRD), we identified a total of 7294 and 4151 consecutive AF patients aged 80 years or older with a CHADS2 score≥2 who met the enrollment criteria (generally similar to ELDERCARE-AF) taking VLD and RD NOACs from June 1, 2012, to December 31, 2019, respectively. Propensity-score stabilized weighting (PSSW) was used to balance covariates across study groups. Patients were followed up from the first date of prescription for NOACs until the first occurrence of any study outcome, death, or until the end date of the study period (December 31, 2020). After PSSW, VLD NOAC was associated with a comparable risk of ischemic stroke/systemic embolism and major bleeding but a higher risk of major adverse limb events (MALEs) requiring lower limb revascularization or amputation (Hazard ratio [HR]:1.54, 95% confidential interval [CI]:1.09-2.18; p=0.014), venous thrombosis (HR:3.75,95%CI:1.56-8.97; p=0.003), and all-cause mortality (HR:1.21,95%CI:1.15-1.29; p<0.001) compared to RD NOACs. VLD NOACs showed worse outcomes in most net clinical benefits (NCOs). The main result was consistent based on on-treatment analysis or accounting for death as a competing risk. In general, the advantage of NCOs for the RD NOACs over VLD NOACs persisted in most high-risk subgroups, consistent with the main analysis (P for interaction>0.05). Use of VLD NOACs was associated with a greater risk of arterial and venous thrombosis, death as well as the composite outcomes, when compared to that of RD NOAC in high-risk elderly AF patients at increased bleeding risk. Thromboprophylaxis with RD NOAC is still preferable over VLD NOAC for the majority of elderly AF patients at increased bleeding risk.

Transcatheter Aortic Valve Implantation by Intercostal Access: Initial Experience with a No-Touch Technique.

Transcatheter aortic valve implantation (TAVI) is now a well-established therapeutic option in an elderly high-risk patient cohort with aortic valve disease. Although most commonly performed via a transfemoral route, alternative approaches for TAVI are constantly being improved. Instead of the classical mini-sternotomy, it is possible to achieve a transaortic access via a right anterior mini-thoracotomy in the second intercostal space. We describe our experience with this sternum- and rib-sparing technique in comparison to the classical transaortic approach. Our retrospective study includes 173 patients who were treated in our institution between January 2017 and April 2020 with transaortic TAVI via either upper mini-sternotomy or intercostal thoracotomy. The primary endpoint was 30-day mortality, and secondary endpoints were defined as major postoperative complications that included admission to the intensive care unit and overall hospital stay, according to the Valve Academic Research Consortium 3. Eighty-two patients were treated with TAo-TAVI by upper mini-sternotomy, while 91 patients received the intercostal approach. Both groups were comparable in age (mean age: 82 years) and in the proportion of female patients. The intercostal group had a higher rate of peripheral artery disease (41% vs. 22%, p = 0.008) and coronary artery disease (71% vs. 40%, p < 0.001) with a history of percutaneous coronary intervention or coronary artery bypass grafting, resulting in significantly higher preinterventional risk evaluation (EuroScore II 8% in the intercostal vs. 4% in the TAo group, p = 0.005). Successful device implantation and a reduction of the transvalvular gradient were achieved in all cases with a significantly lower rate of trace to mild paravalvular leakage in the intercostal group (12% vs. 33%, p < 0.001). The intercostal group required significantly fewer blood transfusions (0 vs. 2 units, p = 0.001) and tended to require less reoperation (7% vs. 15%, p = 0.084). Hospital stays (9 vs. 12 d, p = 0.011) were also shorter in the intercostal group. Short- and long-term survival in the follow-up showed comparable results between the two approaches (30-day, 6-month- and 2-year mortality: 7%, 23% and 36% in the intercostal vs. 9%, 26% and 33% in the TAo group) with acute kidney injury (AKI) and reintubation being independent risk factors for mortality. Transaortic TAVI via an intercostal access offers a safe and effective treatment of aortic valve stenosis.

Imaging of Bioprosthetic Valve Dysfunction after Transcatheter Aortic Valve Implantation.

Transcatheter aortic valve implantation (TAVI) has become the standard of care in elderly high-risk patients with symptomatic severe aortic stenosis. Recently, TAVI has been increasingly performed in younger-, intermediate- and lower-risk populations, which underlines the need to investigate the long-term durability of bioprosthetic aortic valves. However, diagnosing bioprosthetic valve dysfunction after TAVI is challenging and only limited evidence-based criteria exist to guide therapy. Bioprosthetic valve dysfunction encompasses structural valve deterioration (SVD) resulting from degenerative changes in the valve structure and function, non-SVD resulting from intrinsic paravalvular regurgitation or patient-prosthesis mismatch, valve thrombosis, and infective endocarditis. Overlapping phenotypes, confluent pathologies, and their shared end-stage bioprosthetic valve failure complicate the differentiation of these entities. In this review, we focus on the contemporary and future roles, advantages, and limitations of imaging modalities such as echocardiography, cardiac computed tomography angiography, cardiac magnetic resonance imaging, and positron emission tomography to monitor the integrity of transcatheter heart valves.

Clinicopathological features and outcome in elderly patients with idiopathic membranous nephropathy

Background Idiopathic membranous nephropathy (IMN) is the leading cause of nephrotic syndrome in the elderly. The treatment of idiopathic membranous nephropathy is quite challenging due to the particularity of elderly patients. This study intends to investigate the clinicopathological characteristics and initial therapeutic effect of idiopathic membranous nephropathy among elderly patients. Methods A retrospective study of 67 elderly patients (58.2% male, median age 69.0 years, range, 65–83 years) with biopsy-proven membranous nephropathy was conducted at Guangdong Provincial People’s Hospital from 2016 to 2020. Data on clinicopathological characteristics and initial therapeutic effects were analyzed. Results Of the 67 patients, the mean eGFR of overall patients was 66.49 mL/min/1.73m2 while the median urine protein-to-creatinine ratio (uPCR) and urine albumin-to-creatinine ratio (uACR) was 5676.73 mg/g and 2951.56 mg/g, respectively. Pathological data revealed that the membranous Churg’s stage II was the most frequent (71.64%). Moreover, glomerular PLA2R antigen fluorescence intensity of (+) and IgG4 antigen fluorescence intensity of (++) were detected in 63.6% and 86.4% of all patients, respectively. Overall, 44 patients, accounting for 65.7%, achieved remission including complete remission and partial remission within 1 year after renal biopsy. Compared with a non-remission group, the levels of uPCR (6274.6 vs. 3235.6 mg/g, p = 0.007) and uACR (3433.6 vs. 1773.2 mg/g, p = 0.017) were significantly higher in remission group. The proportion of immunosuppressive therapy in the remission group was also higher (86.4% vs. 30.4%, p < 0.01). Compared with conservative treatment, patients with combined treatment with glucocorticoid and cyclophosphamide (CTX) or glucocorticoid and calcineurin inhibitor (CNIs) achieved higher remission rate (glucocorticoid plus cyclophosphamide vs. conservative treatment, 84.6% vs. 27.3%, p = 0.001; glucocorticoid plus calcineurin inhibitor vs. conservative treatment, 88.0% vs. 27.3%, p < 0.001). Further analysis showed that compared with patients who underwent conservative treatment, the proportion of males, the levels of uPCR, uACR, BUN, Scr, CysC and PLA2R antigen-positive staining rate in kidney biopsy were higher in those who underwent combined treatment with glucocorticoid and CTX, while the levels of eGFR, TP and ALB were lower (p < 0.05). In addition, patients who received combined treatment with glucocorticoid and CNIs had higher levels of uPCR, uACR, TC and lower levels of TP, ALB than those who received conservative treatment (p < 0.05). Moreover, there were no statistically significant differences in the 1-year progression rate in eGFR between the immunosuppressive treatment group and conservative treatment group (3.3 vs. 0.2 ml/min/1.73m2, p = 0.852). Conclusions Most elderly patients diagnosed with IMN had multiple comorbidities, and the membranous Churg’s stage II was most common. The glomerular PLA2R and IgG4 antigen deposition were frequently detected accompanied by glomerulosclerosis and severe tubulointerstitial injury. For high-risk elderly patients with severe proteinuria, early initial immunosuppressive therapy could achieve a higher urinary protein remission rate. Therefore, it is crucial for clinicians to balance the risks and benefits of immunosuppressive therapy based on clinical and pathological characteristics and develop individualized treatment regimens for elderly patients with IMN.

Risk factors of osteoporosis in elderly inpatients: A cross-sectional single-centre study.

Objective: This study aimed to identify factors significantly associated with the occurrence of osteoporosis in elderly and very elderly patients. Methods: Elderly hospitalized patients who were older than 60years old, from the Rehabilitation Hospital from December 2019 to December 2020 were selected. Barthel index (BI), nutritional assessment, the causes of bone mineral density (BMD) reductions in elderly and elderly patients were analysed. Results: A total of 94 patients (83.56 ± 8.37years old) were enrolled. With increasing age, the BMD of the lumbar spine, femoral neck, and femoral shaft of elderly patients significantly decreased, and the incidence of osteoporosis (OP) significantly increased. The BMD of the lumbar spine was negatively correlated with female and positively correlated with serum 25-hydroxyvitamin D levels, the difference between actual body weight and ideal body weight, and blood uric acid levels; The BMD of the femoral neck was negatively correlated with age and female, and positively correlated with height and geriatric nutrition risk index score. The BMD of the femoral shaft was negatively correlated with female and positively correlated with BI. Conclusion: With increasing age, the BMD of the lumbar spine and the femoral shaft significantly decreased, and the incidence of OP significantly increased in elderly and very elderly patients. Aric acid may protect bone health in elderly patients. Early attention to the nutritional status, exercise capacity, 25-hydroxyvitamin D level, and blood uric acid level in the elderly population can help identify high-risk elderly patients with OP.

Efficacy of a paper-based interleukin-6 test strip combined with a spectrum-based optical reader for sequential monitoring and early recognition of respiratory failure in elderly pneumonia-a pilot study.

Introduction: Community-acquired pneumonia (CAP) is lethal in elderly individuals who are more vulnerable to respiratory failure and require more emergency ventilation support than younger individuals. Interleukin-6 (IL-6) plays a crucial role and has predictive value in CAP; high serum IL-6 concentrations in adults are associated with high respiratory failure and mortality rates. Early detection of IL-6 concentrations can facilitate the timely stratification of patients at risk of acute respiratory failure. However, conventional enzyme-linked immunosorbent assay (ELISA) IL-6 measurement is laborious and time-consuming. Methods: The IL-6 rapid diagnostic system combined with a lateral flow immunoassay-based (LFA-based) IL-6 test strip and a spectrum-based optical reader is a novel tool developed for rapid and sequential bedside measurements of serum IL-6 concentrations. Here, we evaluated the correlation between the IL-6 rapid diagnostic system and the ELISA and the efficacy of the system in stratifying high-risk elderly patients with CAP. Thirty-six elderly patients (median age: 86.5years; range: 65-97years) with CAP were enrolled. CAP diagnosis was established based on the Infectious Diseases Society of America (IDSA) criteria. The severity of pneumonia was assessed using the CURB-65 score and Pneumonia Severity Index (PSI). IL-6 concentration was measured twice within 24h of admission. Results: The primary endpoint variable was respiratory failure requiring invasive mechanical or non-invasive ventilation support after admission. IL-6 rapid diagnostic readouts correlated with ELISA results (p < 0.0001) for 30 samples. Patients were predominantly male and bedridden (69.4%). Ten patients (27.7%) experienced respiratory failure during admission, and five (13.9%) died of pneumonia. Respiratory failure was associated with a higher mortality rate (p = 0.015). Decreased serum IL-6 concentration within 24h after admission indicated a lower risk of developing respiratory failure in the later admission course (Receiver Operating Characteristic [ROC] curve = 0.696). Conclusion: Sequential IL-6 measurements with the IL-6 rapid diagnostic system might be useful in early clinical risk assessment and severity stratification of elderly patients with pneumonia. This system is a potential point-of-care diagnostic device for sequential serum IL-6 measurements that can be applied in variable healthcare systems.

Risk stratification and beneficiary selection among elderly nasopharyngeal carcinoma patients from concurrent chemoradiotherapy combined with induction chemotherapy.

This study aims to evaluate the risk stratification among elderly Nasopharyngeal carcinoma (NPC) patients (≥60 years old) and select the beneficiaries from concurrent chemotherapy (CCRT) combined with induction chemotherapy (IC). A total of 909 elderly non-metastatic NPC patients treated with cisplatin-based CCRT or IC + CCRT between January 2007 and December 2016 were included. Prognostic nomograms were generated according to clinical characteristics and serum biomarkers. The survival outcomes of patients treated with CCRT versus IC + CCRT were compared in three well-matched risk groups (high, medium, and low risk) after PSM analysis. Benefit of IC in people older or younger than 70 years and effect of different IC regimens and cycles on prognosis were analyzed. Nomograms of overall survival (OS) (C-index: 0.64, 95% CI, 0.61-0.89) and disease special survival (DSS) (C-index: 0.65, 95% CI, 0.62-0.71) showed good prognostic accuracy. The nomogram for DSS included variables of age, gender, ACE, EBV DNA, N stage, and T stage. OS included variables of age, smoking history, ACE, ALB, EBV DNA, N stage, and T stage. The corresponding 5-year OS rates of high, medium and low risk groups were 87.4%, 82.2%, and 60.9%, respectively (p < 0.001), while the 5-year DSS rates were 92.2%, 84.3%, and 69.0%, respectively (p < 0.001). In the high risk group, IC + CCRT led to significantly higher 5-year OS and DSS rate compared with CCRT (5-year OS rate, 73.5% versus 51.8%, p=0.006; 5-year DSS rate, 81.4% versus 61.3%, p=0.002). While in the medium and low risk groups, OS and DSS were not significantly different (OS: p=0.259, 0.186; DSS: p=0.29, 0.094). Subgroup analysis showed in the high risk group, only people younger than 70 years old could benefit from IC. TPF and IC cycles of three could lead to the best survival results. Compared with CCRT, OS, and DSS among high risk elderly patients were significantly improved by the addition of IC in patients younger than 70 years old. TPF and three IC cycles were recommended.

Minimally invasive direct coronary artery bypass and percutaneous coronary intervention followed by transcatheter aortic valve implantation: A promising concept in high-risk octogenarians.

In this article, we present our initial clinical experience with staged minimally invasive direct coronary bypass (MIDCAB), percutaneous coronary intervention (PCI), and transcatheter aortic valve implantation (TAVI) in high-risk octogenarians (Hybrid). The use of percutaneous techniques for managing structural heart diseases, especially in elderly high-risk patients, has revolutionized the treatment of structural heart diseases. These procedures are present predominantly being offered as isolated interventions. The feasibility, clinical benefit, and outcomes of combining these techniques with MIDCAB have not been sufficiently explored and have subsequently been underreported in the contemporary literature. Four consecutive octogenarians with severe aortic stenosis (AS) and complex coronary artery disease (CAD) that were at high risk for conventional surgery with extracorporeal circulation (ECC) were discussed in our Multidisciplinary Heart Team (MDH). Our MDH consisted of an interventional cardiologist, cardiac surgeon, and cardiac anesthesiologist. A hybrid approach with the alternative strategy comprising of MIDCAB, PCI, and TAVI in a staged fashion was agreed on. All 4 patients had both PCI/stenting and MIDCAB prior to deployment of the TAVI-prosthesis. From January 2019 to December 2020, 4 consecutive patients aged between 83 and 85 (3 male/1 female) years were scheduled for MIDCAB/PCI followed by percutaneous treatment of severe symptomatic AS. Intraoperatively, one patient was converted to full sternotomy, and surgery was performed by off-pump coronary artery bypass grafting. The overall procedural success rate was 100% in all 4 patients with resolution of their initial presenting cardiopulmonary symptoms. There were no severe complications associated with all hybrid procedures. There was no 30-day mortality in all patients. All patients were discharged home with a median hospital stay ranging between 9 and 25 days. All patients have since then been followed-up regularly. There was one noncardiac-related mortality at 6-months postsurgery. All other patients were well at 1-year follow-up with improved New York Heart Association Class II. In a selected group of elderly, high prohibitive risk patients with CAD and severe symptomatic AS, a staged approach with MIDCAB and PCI followed by TAVI can be safely performed with excellent outcomes. We advocate a MDH-based preliminary evaluation of this patient cohort in selecting suitable patients and appropriate timing of each stage of the hybrid procedure.

Derivation and validation of a risk prediction score for nonsteroidal anti-inflammatory drug-related serious gastrointestinal complications in the elderly.

Few studies have quantified the impact of risk factors on GI complications in elderly nonsteroidal anti-inflammatory drug (NSAID) users. This study aimed to develop and validate a risk prediction score for severe GI complications to identify high-risk elderly patients using NSAID. We used the following two Korean claims datasets: customized data with an enrolment period 2016-2017 for model development, and the sample data in 2019 for external validation. We conducted a nested case-control study for model development and validation. NSAID users were identified as the elderly (≥65 years) who received NSAIDs for more than 30 days. Serious GI complications were defined as hospitalizations or emergency department visits, with a main diagnosis of GI bleeding or perforation. We applied the logistic least absolute shrinkage and selection operator (LASSO) regression model for variable selection and model fitting. We identified 8176 cases and 81 760 controls with a 1:10 matched follow-up period in the derivation cohort. In the external validation cohort, we identified 372 cases from 254 551 patients. The risk predictors were high-dose NSAIDs, nonselective NSAID, complicated GI ulcer history, male sex, concomitant gastroprotective agents, relevant co-medications, severe renal disease and cirrhosis. Area under the receiver operating characteristic curve was 0.79 (95% confidence interval, 0.77-0.81) in the external validation dataset. The prediction model may be a useful tool for reducing the risk of serious GI complications by identifying high-risk elderly patients.

Evaluation of oral care using MA-T gel for high-risk patients: a pilot study

BackgroundOral care with gel is a common method for preventing aspiration in high-risk patients. An oral care gel is used to clean and moisturize the oral cavity. However, the effects of gel care on the oral bacteria remain unclear. In this pilot study, we described a matching transformation system (MA-T) for elderly high-risk patients. MA-T is an on-demand aqueous chlorine dioxide solution that provides excellent safety and has various antimicrobial activities, even in the presence of abundant organic compounds. This study investigated the effects of MA-T gel in patients requiring nursing care.Materials and methodsPatients who were hospitalized for nursing care were included in this study. No drugs and foods were administered orally. Oral bacteria and intraoral humidity were examined by daily care using MA-T gel. Moreover, oral membranous substances were analyzed and material from the oral cavity was cultured on selective media for identifying opportunistic organisms.ResultsMembranous substances were present in the oral cavities of all patients. The number of bacteria decreased, and oral moisture improved, after treatment with MA-T gel. Moreover, oral humidity was also controlled with the continued use of MA-T gel. MA-T gels should be used not only for professional care but also on a daily basis for better oral care. Furthermore, the results of bacterial cultures showed that MA-T controls the propagation of opportunistic bacterial infections.ConclusionMembranous substances may be observed in the oral cavity of individuals requiring nursing care for tube feeding. The results of this pilot study suggest that MA-T, a novel disinfectant, can be used for oral care in the elderly to reduce the risk of aspiration-pneumonia.

Transcranial Doppler: A Beginning of a New Era for Stroke Diagnosis

Transcranial Doppler (TCD) is an intracranial neurovascular exam that provides a real-time, rapid, non-invasive ultrasound technique to analyze cerebrovascular function. It uses high-frequency sound waves to assess the blood flow velocity, detect the deficit that causes focal vascular stenosis, and diagnose the embolic signals inside these arteries. Moreover, it can be used to analyze particular vascular territory of physiologic health by measuring cerebral vasoreactivity, cerebral autoregulation, and functional hyperemia. The information obtained from these examinations is increasingly becoming pertinent for therapeutic decision-making. In this study, we are going to focus on a comparative analysis of TCD findings using clinical and other modalities and assess the specificity, sensitivity, and positive and negative predictive value of TCD findings in Asymptomatic and Symptomatic high-risk elderly patients. Furthermore, we will study the clinical usefulness of TCD in evaluating patients with cerebrovascular accidents (CVA).

Chinese expert consensus on antithrombotic management of high-risk elderly patients with chronic coronary syndrome.

The prevalence and mortality of coronary artery disease (CAD) in China are still at an increasing stage. CAD can be classified as acute coronary syndrome (ACS) or chronic coronary syndrome (CCS). CCS is the main manifestation type of elderly patients with CAD, with a large number of patients, long course of disease, and poor prognosis, leading to decreased quality of life and heavy disease burden and economic burden. Especially in patients with high-risk CCS, the case fatality rate and total mortality are high. In order to better standardize the antithrombotic treatment of elderly patients with high-risk CCS, the Geriatrics Branch of the Chinese Medical Association organizes domestic experts to develop this consensus for clinicians' reference based on published clinical research evidence, combined with relevant guidelines, consensus, and expert recommendations in China and abroad.

Denosumab in elderly osteoporotic patients. A narrative review.

Denosumab, an antiresorptive agent, has shown results in improving bone mineral density and reducing fractures in postmenopausal women. While bisphosphonates are commonly used as initial therapy for osteoporosis, some studies suggest that denosumab could be an alternative initial treatment for high-risk patients, particularly the elderly population. This narrative literature review aimed to assess the use of denosumab in elderly individuals with osteoporosis, excluding its oncology applications. Multiple online databases including Scopus, PubMed, EMBASE, Cochrane Central Register of Controlled Trials (CENTRAL), and PEDro were searched for relevant English-language trials. Between about hundred identified, the review selected 21 articles full-meeting the inclusion criteria. These papers all reporting that Denosumab demonstrated significant efficacy in reducing vertebral and nonvertebral fractures in postmenopausal and senile osteoporosis. Even if limited evidence exists regarding its long-term effectiveness in elderly patients, nevertheless denosumab may be considered a first-line treatment for high-risk elderly patients with senile osteoporosis, particularly for those unable to take bisphosphonates. It has shown superior outcomes in improving bone density and reducing fracture risk, even in frail elderly individuals. Long-term use of denosumab has been reported as safe and effective, enhancing treatment compliance and outcomes.

Evaluation of the Relationship Between Bleeding Severity and Platelet Mass Index in Geriatric Patients with Upper Gastrointestinal Bleeding in the Emergency Department

Aim: Platelet mass index (PMI) is closely correlated with platelet function in various diseases. In the present study, we aimed to evaluate the use of PMI in predicting bleeding severity and mortality in geriatric patients with acute upper gastrointestinal (GI) bleeding. Material and Methods: This study is a retrospective study. Local ethics committee approval was obtained. It enrolled patients aged 65 years or older who presented to the emergency department (ED) with upper GI bleeding. The patients’ demographic data, comorbid disorders, results of laboratory studies and endoscopic procedures, hospital outcomes, and 30-day mortality rate were evaluated. A p-value of less than 0.05 was considered statistically significant. Results: This study included 167 patients. Among them, 40.1% were female, and their median age was 79 (IQR 25-75, 71-86) years. The median Rockall score was 4 (IQR 25-75, 2-5); and the 30-day mortality rate was 13.2 % (n=22). The most common causes of bleeding were duodenal/gastric ulcer and/or erosive gastritis. A comparison of the non-surviving and surviving patients showed that the non-survivor ones were hemodynamically more unstable, had a greater rate of heart failure, higher BUN, creatinine, and Rockall score, and lower platelet count, albumin, and PMI (p=0.026, p=0.029, p=0.048, p=0.018, p=0.013, p&amp;lt;0.001, p=0.025, respectively). Conclusion: Early detection and appropriate management of high-risk elderly patients may contribute to shortening the time to stabilize these patients. Our study showed that PMI was closely associated with mortality in elderly patients who had GI bleeding. We showed that, as PMI decreased, the patients had lower survival and more severe GI bleeding.

HIGH-RISK ELDERLY SCREENING IN MEDICAL INTENSIVE CARE UNIT

Abstract Geriatrics care in medical intensive care units (MICU) establishes a unique opportunity in early screening of High Risk Elderly (HRE) patients admitted for critical care. Many MICUs do not have a standard protocol to screen for HRE patients as part of their daily huddle. Our program is a quality improvement initiative to improve early identification of HRE patients in the MICU. HRE patients were identified based on nursing specific screening triggers at one of the Regional Hospitals of a large teaching hospital in Northeast Ohio.The program was designed as a part of geriatrics care expansion at regional hospital sites. Identified patients were discussed in daily huddles to determine unique geriatric needs in caring for these patients. A geriatrics co-management team was engaged in comprehensive geriatric assessments and care transition when it was needed. Geriatrics care in MICU demonstrates a unique opportunity in early identification of HRE patients. This helps to support a patient -centered approach in caring for critically ill elderly patients. The program would lay foundations in early screening for risk factors and optimizing elderly care in MICU.

Oral Anticoagulants in Very Elderly Nonvalvular Atrial Fibrillation PatientsWith High Bleeding Risks: ANAFIE Registry.

Data on the effectiveness and safety of oral anticoagulant (OAC) agents in very elderly nonvalvular atrial fibrillation patients with high bleeding risk are lacking. This study examined 2-year outcomes and effects of OAC agents among these patients using the ANAFIE (All Nippon Atrial Fibrillation in the Elderly) registry (N=32,275) data. Patients were classified into high-risk (age:≥80 years; CHADS2 score:≥2; and presence of≥1 bleeding risk factor: creatinine clearance of 15-30mL/minute, prior bleeding at critical sites, body weight of≤45kg, or continuous antiplatelet use) and reference groups. In the high-risk (n=7,104) and reference (n=25,171) group patients, 89.0% and 93.4%, respectively, used OAC agents. Of these, respectively, 30.1% and 24.2% used warfarin, and 58.9% and 69.1% used direct-acting OAC (DOAC) agents. Compared with the reference group, the high-risk group had higher incidences of stroke/systemic embolism, major bleeding, intracranial hemorrhage, gastrointestinal bleeding, cardiovascular events, and all-cause death. In the high-risk group, DOAC agent use vs nonuse of OAC agents was associated with reduced incidences of stroke/systemic embolism (HR: 0.53; 95%CI: 0.36-0.79) and all-cause death (HR: 0.65; 95%CI: 0.52-0.81) but not with major bleeding (HR: 1.09; 95%CI: 0.63-1.89). DOAC agents were superior to warfarin in effectiveness and safety. For high-risk patients, history of major bleeding, severe liver dysfunction, and falls within 1 year were independent risk factors for major bleeding. High-risk elderly nonvalvular atrial fibrillation patients had higher event incidences. DOAC agents were associated with reduced risk of stroke/systemic embolism and all-cause death vs nonuse of OAC agents or warfarin.

Middle meningeal artery embolization for chronic subdural hematoma in elderly patients at high risk of surgical treatment.

The purpose of this study was to evaluate the effectiveness of middle meningeal artery embolization (MMAE) in elderly high-risk patients with symptomatic chronic subdural hematoma (CSDH) in terms of reduction in hematoma volume and recurrence rate. We retrospectively reviewed data prospectively collected from nine patients who underwent 13 MMAE for CSDH between June 2017 and May 2022. The volume of the subdural hematoma was measured using a computer-aided volumetric analysis program. Hematoma volume changes during the follow-up period were analyzed and clinical outcomes were evaluated. The mean follow-up period was 160 days (range, 46-311 days). All procedures were technically successful and there were no procedure-related complications. Of the 13 MMAE, 84% (11 out of 13 hemispheres) showed mean 88% of reduction on follow-up volumetric study with eight cases of complete resolution. There was one refractory case with MMAE which had been performed multiple burr-hole trephinations, for which treatment was completed by craniotomy and meticulous resection of multiple pseudomembranes. There was no recurrent case during the follow-up period, except for refractory case. MMAE for CSDH in selected high-risk elderly patients and relapsed patients might be effective. Despite the small cohort, our findings showed a high rate of complete resolution with no complications. Further prospective randomized trials are warranted to evaluate its usefulness as a primary treatment option for CSDH.
