Utilization of Surgical Fixation for Distal Radius Fractures in the United States: A Population-Based Cohort Study

In contrast to younger adult populations, clinical practice guidelines state that there is no difference in long-term functional outcomes in surgically versus nonoperatively treated distal radius fractures in patients ≥65 years old. In this study, we asked the following questions: (1) has treatment for distal radius fractures in younger and older adult populations changed over time? (2) What patient and surgeon factors are associated with treatment trends? Using a national administrative claims database, we identified patients aged ≥18 years with isolated, closed distal radius fractures, subdivided by age (18-64 years, ≥65 years old). We characterized the proportion of patients who underwent open reduction and internal fixation (ORIF) over time. We stratified our analysis by surgeon subspecialty, region, and mean area income. Changes in ORIF utilization over time were evaluated using linear regression models. The proportion of distal radius ORIF, including in patients aged ≥65 years, increased from 10.4% in 2012 to 15.1% in 2020. Of the ORIF procedures performed, hand surgeons accounted for an increasing proportion over time, with a corresponding decrease in those performed by general orthopedic surgeons. The proportion of ORIF increased over time in all US regions, with the largest rate of increase in the Midwest for patients aged ≥65 years and Northeast for patients aged 18-64 years. Patients living in areas with mean family income ≥$65,000 were more likely to undergo ORIF. The proportion of distal radius ORIF including in older adult populations is increasing in all US regions, and an increasing proportion is performed by hand surgeons. Further analysis of the drivers of these trends is warranted, given the rising incidence of surgical treatment in older patients, which could reflect evolving patient activity demands and suggest a need to further evaluate conventional treatment algorithms based on age.

Real-World Evidence of Feasible Assessment and Intervention in Cardiovascular Physical Therapy for Older Patients With Heart Failure - Insight From the J-Proof HF of the Japanese Society of Cardiovascular Physical Therapy.

This study aimed to clarify the feasibility of cardiovascular physical therapy assessment and intervention in older patients with heart failure (HF) in Japan. We performed a secondary analysis of data from a nationwide multicenter registry (the J-Proof HF), and enrolled consecutive HF patients aged ≥65 years who were prescribed cardiovascular physical therapy during hospitalization from December 2020 to March 2022. Of the 9,650 enrolled patients (median age 83.0 years; 49.8% male), the availability rate of comorbidities and assessments was >95%. In the activities of daily living (ADL) assessment, the Barthel Index (BI) and Functional Independence Measure were 97.6% and 60.4%, respectively. The results of the physical therapy assessment indicated completion rates of ≥80%, with lower rates of <60% for gait speed and short-performance physical battery in the group with a BI of <85 points. In physiotherapy intervention, gait training and muscle strength training were performed by >80% of patients, whereas aerobic exercise and resistance training were performed by 35.4% and 2.6% patients, respectively. Our results in this study indicated that medical findings, such as comorbidities, echocardiography, and laboratory findings, were considered a feasible assessment that could be confirmed at all hospitals. Gait training, ADL training, and muscle strength training are much more common than exercise training in older patients with HF.

Midostaurin added to 10-day decitabine, for patients unfit for intensive chemotherapy with AML and higher risk MDS, irrespective of FLT3 mutational status, does not improve outcome.

The treatment of older patients with acute myeloid leukemia (AML) considered unfit for receiving intensive chemotherapy is challenging. Based on the hypothesis that addition of the broad tyrosine kinase inhibitor (TKI) midostaurin could improve the response to hypomethylating agents, irrespective of FLT3 gene mutational status, we conducted a randomized phase II multicenter study to assess the tolerability and efficacy of the addition of midostaurin to a 10-day schedule of decitabine in unfit (i.e. Hematopoietic Cell Transplantation Comorbidity Index (HCT-CI) ≥ 3) AML and higher risk myelodysplasia (MDS) patients (HOVON155 trial). In total, 140 eligible patients were randomly (1:1) assigned to treatment with 10-days of decitabine alone (N = 70) or combined with midostaurin (50mg bid;starting the day following the last dose of decitabine), (N = 70). Addition of midostaurin was well tolerated and the number of AEs was comparable for both treatment arms. Early death rates (< 30 days) were similar as well (10%). In the decitabine plus midostaurin arm 24% reached CR/CRi, the median OS was 4.8 months and 1-yrs OS was 31% which compared with 34% CR/CRi, median OS of 7.4 months and 1-yrs OS of 37% for the decitabine alone group (NS). Thus, while the addition of midostaurin appears safe, it does not enhance therapeutic efficacy of decitabine in unfit AML patients.

B-095 The level of procalcitonin is a biomarker for differentiation between pathogenic and non-pathogenic bacteria

Abstract Background Sepsis is caused by bacteria infected in the bloodstream and the body’s inability to control inflammation. Procalcitonin (PCT) is a biomarker of infection in patients with sepsis, the severity of the infection, and whether the patient is responding to therapy. Thus, diagnostics and early treatment are very important for doctors and patients. In a hospital concerned with sepsis in patients, a doctor ordered a PCT level and hemoculture before treating an antibiotic on a patient whose doctor suspects sepsis. The objective of this study is to compare the PCT level in the blood and hemoculture results in patients. Methods In this study, we evaluated the patients who suspected sepsis disease and were admitted to the Uttaradit Hospital, Thailand, between October 2022 and October 2023. The patients were divided into two groups: those with positive hemoculture results (sepsis group) and those with negative hemoculture results (non-sepsis group). The PCT levels in the blood were measured on Alinity ci analyzers and compared between the two groups to determine if there was a significant difference. Additionally, clinical data such as age and gender were collected to assess their potential impact on PCT levels and hemoculture results. Results The results of the study showed that the sepsis group had significantly higher PCT levels compared to the non-sepsis group. And the difference in PCT levels between the sepsis and non-sepsis groups was considerably more marked for patients older than 60. Furthermore, there was no significant difference in PCT levels based on gender in either group. Conclusions This finding suggests that measuring PCT levels could potentially serve as a diagnostic tool for identifying sepsis in patients. A patient age may be a contributing factor to the severity of sepsis and could potentially be used as a marker for early detection and intervention in older patients. Further research is needed to validate these results and explore the clinical implications of using PCT as a biomarker for sepsis diagnosis.

Comparison of surgical and conservative therapy in older patients with distal radius fracture: a prospective randomized clinic al trial

IntroductionThe distal radius fracture is considered the most common fracture in humans. For fractures classified as Arbeitsgemeinschaft für Osteosynthese (AO) 23-C1 + C2, there is no consensus on treatment in older patients due to inconsistent study results. The aim of this study was to compare conservative and surgical treatment in relation to wrist function and satisfaction in patients older than 65 years.MethodsIn this prospective randomized clinical trial, patients aged older than 65 years who suffered an isolated AO-classified C1 or C2 distal radius fracture were randomized to surgical treatment using palmar plate osteosynthesis or conservative treatment. Patient-rated wrist evaluation (PRWE) score and disabilities of arm, shoulder, and hand (DASH) was assessed 3, 6 and 12 months post-interventionally. Satisfaction, range of motion (ROM) and pain scores were evaluated at 6 weeks and 3, 6 and 12 months post-interventionally.ResultsA total of 80 patients with a mean age of 77.3 years (± 6.1 years) in the conservative group and 72.5 years (± 5.3 years) in the surgery group were included. Both the PRWE score, and the DASH score showed a statistically significant difference between the two groups after 3 months, 6 months and 12 months (p < 0.001). Patients in the surgical cohort showed a statistically significant higher satisfaction at the 6-week, 6-month and 12-month follow-up (p < 0.001 6 weeks + 12 months; p = 0.004 6 months).ConclusionIn this prospective randomized study, surgical treatment proved to be superior to conservative treatment in terms of the primary outcome variable PRWE score. Satisfaction was significantly better in the surgical group.

Perioperative pain management intervention in older patients with hip fracture in an orthogeriatric unit. A controlled before/after study assessing an audit and feedback intervention (PAIN-AGE)

BackgroundPostoperative pain delays ambulation, extends hospital stay, reduces the probability of recovery, and increases risk of long-term functional impairment. Pain management in hip fractured patients poses a challenge to the healthcare teams. Older adults are more vulnerable to opioid-associated side effect and it is primordial to minimize their exposure to opioids. Acetaminophen is associated with reduced opioid use so we need to focus on acetaminophen use in first-line analgesia.MethodsWe conducted a controlled before/after study to assess the ability of an audit and feedback (A&F) intervention built with nurses to improve the quality of perioperative pain management in older patients hospitalized for hip fracture in an orthogeriatric unit (experimental group) versus a conventional orthopedic unit (no A&F intervention). The primary endpoint was the percentage of patients who received 3 g/day of acetaminophen during the three postoperative days, before and after the A&F intervention. Secondary endpoints included nurses’ adherence to medical prescriptions, clinical data associated with patients and finally factors associated with intervention. The significative level was set at 0.05 for statistical analysis.ResultsWe studied data from 397 patients (mean age 89 years, 75% female). During the postoperative period, 16% of patients from the experimental group received 3 g/day of acetaminophen before the A&F intervention; the percentage reached 60% after the intervention. The likelihood of receiving 3 g/day of acetaminophen during the postoperative period and adhering to the medical prescription of acetaminophen were significantly increased in the experimental group as compared with the control group. The patient’s functional status at discharge (assessed by Activities of Daily Living scores) was significantly better and the length of hospital stay significantly reduced after the A&F intervention.ConclusionOur controlled before/after study showed that an A&F intervention significantly improved perioperative pain management in older adults hospitalized for hip fracture. Involving teams in continuous education programs appears crucial to improve the quality of pain management and ensure nurses’ adherence to medical prescriptions.

Treatment of Acquired Deforming Hypertonia with Botulinum Toxin in Older Population: A Retrospective Study.

Acquired deforming hypertonia (ADH) affects the daily care of numerous nursing home residents. The aim of this study was to analyze the practice, aims, and effectiveness of botulinum toxin injections (BTxis) in the treatment of older patients with contractures, an indication for which BTxis are still underused. Data were extracted retrospectively from medical records regarding population, contractures, and injections. A prospective analysis was conducted to evaluate treatment goals set by goal attainment scaling (GAS) at T0 and at T1, to evaluate the therapeutic effects. We also recorded the occurrence of side effects, using a telephone questionnaire. This study included 41 patients older than 70 years who had received one or more BTxis for the first time between January 2018 and December 2021. Most of the older people we included lived in an institution (66%), manifested severe dependence, and presented significant morbi-mortality (37% of the patients died in the year after the last injection). The main objectives of these injections were purely comfort, without any functional goals. The GAS scores suggested effectiveness for comfort GAS scores. No complications were recorded. This study highlights the BTxis potential to address the needs of a larger number of older patients with ADH.

MS treatment de-escalation: review and commentary.

Almost all currently licensed disease-modifying therapies (DMTs) for MS treatment require prolonged if not lifelong administration. Yet, as people age, the immune system has increasingly reduced responsiveness, known as immunosenescence. Many MS DMTs reduce the responsiveness of the immune system, increasing the risks for infections and possibly cancers. As people with MS (pwMS) age, it is recognized that inflammatory MS activity declines. Several studies have addressed de-escalation of DMTs for relapsing MS under special circumstances. Here, we review evidence for de-escalating DMTs as a strategy that is particularly relevant to pwMS of older age. Treatment de-escalation can involve various strategies, such as extended or reduced dosing, switching from high-efficacy DMTs having higher risks to moderately effective DMTs with lesser risks, or treatment discontinuation. Studies have suggested that for natalizumab extended dosing maintained clinical efficacy while reducing the risk of PML. Extended interval dosing of ocrelizumab mitigated the decline of Ig levels. Retrospective and observational discontinuation studies demonstrate that age is an essential modifier of drug efficacy. Discontinuation of MS treatment in older patients has been associated with a stable disease course, while younger patients who discontinued treatment were more likely to experience new clinical activity. A recently completed 2-year randomized-controlled discontinuation study in 260 stable pwMS > 55years found stable clinical multiple sclerosis with only a small increased risk of new MRI activity upon discontinuation. DMT de-escalation or discontinuation in MS patients older than 55years may be non-inferior to continued treatment with immunosuppressive agents having higher health risks. However, despite several small studies, a definite conclusion about treatment de-escalation in older pwMS will require larger and longer studies. Ideally, comparison of de-escalation versus continuation versus discontinuation of DMTs should be done by prospective randomized-controlled trials enrolling sufficient numbers of subjects to allow comparisons for MS patients of both sexes within age groups, such as 55-59, 60-65, 66-69, etc. Optimally, such studies should be 3years or longer and should incorporate testing for specific markers of immunosenescence (such as T-cell receptor excision circles) to account for differential aging of individuals.

Low-Dose Glucocorticoids in Older Patients with Rheumatoid Arthritis: What Does the Evidence Say?

The short-term use of glucocorticoids (GCs) in combination with methotrexate was recommended for the initial treatment of rheumatoid arthritis by the European League Against Rheumatism. A randomized controlled trial (GLORIA) showed that treatment of older patients with low-dose GCs in combination with disease-modifying anti-rheumatic drugs was more efficacious than disease-modifying anti-rheumatic drugs plus placebo in terms of disease activity control and prevention of joint destruction. Glucocorticoid-related adverse events were likely to increase relative to placebo, with no increase in serious adverse events and fractures over 2 years. Observational studies showed an increased risk of serious infections, cardiovascular events, and fractures associated with long-term continuation of GCs in older patients, but the adverse events may be associated not only with GC toxicity but also with poor disease control of rheumatoid arthritis. In the GLORIA study, low-dose GCs during 2 years could be tapered off safely, but many patients had a flare of disease activity after discontinuation of GCs. In the two representative large Japanese registries (IORRA and NinJa), the proportion of patients using GCs and non-tumor necrosis factor inhibitors increased with increasing age at disease onset, with a decreasing trend in methotrexate use. The proportion of patients in remission with GC treatment also increased with increasing age at onset. These suggested that it is not easy to discontinue GCs in older patients. If GCs cannot be terminated in the short term, it may be acceptable to use GCs to control disease activity for up to 2 years.

Impact of rehabilitation unit-based physical activity therapy versus symptomatic supportive treatment on older patients with advanced cancer: a non-randomized controlled study

ObjectivesRelatively few studies have investigated the effects of rehabilitation-based physical activity therapy as a treatment for older patients with advanced cancer. This study evaluated the effects of individualized precise and structured exercise interventions, prescribed by a rehabilitation physician, on fatigue, quality of life (QOL), and physical activity in older patients with advanced cancer.MethodsAfter admission to the rehabilitation department, older cancer patients were divided into groups receiving conventional symptomatic supportive therapy (SST) or physical activity therapy plus conventional symptomatic supportive therapy (PAT). The SST group was given symptomatic supportive treatment, exercised on their own, and were observed at home after their symptoms improved. The PAT group was required to implement physical exercise along with SST, involving 30 min of moderate-intensity exercise per day and 5 days per week, and were discharged after 4 weeks and instructed to continue to exercise outside the hospital. Cancer-related fatigue (CRF) at 4 and 8 weeks was the primary endpoint of the study, while the secondary endpoints included patients’ QOL, physical activity, and exercise adherence rate.ResultsSixty-five patients were included; 37 (56.92%) chose to enter the PAT group, and 28 (43.08%) chose to enter the SST group. After 4 and 8 weeks of treatment, CRF relief and QOL improvement were significantly better in the PAT group than in the SST group (p < 0.05), whereas global health status did not differ between the two treatment groups (T1: p = 0.84; T2: p = 0.92). Mild physical activity significantly increased for the PAT group at T1 and T2 (T1: p = 0.03; T2: p = 0.005). At the T2 time point, the PAT group exhibited a higher level of participation in moderate-intensity physical activities as well as a higher total leisure activity score (p < 0.05). Thirty-three patients (94.29%) completed the PAT exercise program during hospitalization. Only four (12.12%) patients achieved moderate-intensity exercise, while the other 29 (87.88%) patients were able to continue exercising after their exercise intensity was decreased.ConclusionsImplementation of precise and individualized exercise interventions, prescribed by the rehabilitation team, can lead to the reduction of CRF and improvement of QOL, and change in behavior related to physical activity.

The performance of metabolomics-based prediction scores for mortality in older patients with solid tumors

Prognostic information is needed to balance benefits and risks of cancer treatment in older patients. Metabolomics-based scores were previously developed to predict 5- and 10-year mortality (MetaboHealth) and biological age (MetaboAge). This study aims to investigate the association of MetaboHealth and MetaboAge with 1-year mortality in older patients with solid tumors, and to study their predictive value for mortality in addition to established clinical predictors. This prospective cohort study included patients aged ≥ 70 years with a solid malignant tumor, who underwent blood sampling and a geriatric assessment before treatment initiation. The outcome was all-cause 1-year mortality. Of the 192 patients, the median age was 77 years. With each SD increase of MetaboHealth, patients had a 2.32 times increased risk of mortality (HR 2.32, 95% CI 1.59–3.39). With each year increase in MetaboAge, there was a 4% increased risk of mortality (HR 1.04, 1.01–1.07). MetaboHealth and MetaboAge showed an AUC of 0.66 (0.56–0.75) and 0.60 (0.51–0.68) for mortality prediction accuracy, respectively. The AUC of a predictive model containing age, primary tumor site, distant metastasis, comorbidity, and malnutrition was 0.76 (0.68–0.83). Addition of MetaboHealth increased AUC to 0.80 (0.74–0.87) (p = 0.09) and AUC did not change with MetaboAge (0.76 (0.69–0.83) (p = 0.89)). Higher MetaboHealth and MetaboAge scores were associated with 1-year mortality. The addition of MetaboHealth to established clinical predictors only marginally improved mortality prediction in this cohort with various types of tumors. MetaboHealth may potentially improve identification of older patients vulnerable for adverse events, but numbers were too small for definitive conclusions. The TENT study is retrospectively registered at the Netherlands Trial Register (NTR), trial number NL8107. Date of registration: 22–10-2019.

A Retrospective Analysis of Systemic Oncologic Treatment in Older Patients With Advanced Soft-tissue Sarcoma.

Almost half of all patients with soft-tissue sarcoma are over 65 years of age, and the proportion of older patients is increasing. Despite this, they have been underrepresented in clinical trials and only limited data are available to guide treatment decisions. The aim of this study was to investigate treatment patterns and outcomes in older patients with soft-tissue sarcoma. Patients over 50 years old treated for advanced soft-tissue sarcoma at the Helsinki University Hospital between January 2000 and July 2020 were included. Data on patient and tumor characteristics, treatment, and survival were retrospectively collected. A total of 152 patients were included: 14.5% (n=22) were over 75 years old, 34.2% (n=52) were 65-74 and 51.3% (n=78) were 50-64 years old. The outcomes of the oldest group differed from those of younger patients; they were more likely to receive single-agent treatment as first-line therapy (90.9% vs. 28.8% and 24.4%, p<0.001) and had the lowest relative dose-intensity (70% vs. 88% and 95%, p<0.05). They experienced grade three to four hematological adverse events less frequently (38.1%, 56.9% and 72.7%, respectively, p=0.031), and received fewer lines of treatment (median of 1, 2 and 2, respectively, p=0.01). In patients aged ≥75 years, there was no association between further lines of therapy and improved survival. Compared to the youngest group, the oldest patients had a greater risk of dying (hazard ratio=1.7, 95% confidence interval=1.0-2.8, p=0.041) and their median overall survival was only 7.4 months, compared to 14.3 and 12.9 months in the two younger groups. These findings suggest that older patients tolerate chemotherapy when treatment is tailored to their needs but may not benefit as much as younger patients.

Selecting the right treatment: Health outcome priorities in older patients with bladder cancer

IntroductionSelecting the appropriate treatment for older patients with non-muscle invasive (NMIBC) or muscle-invasive bladder cancer (MIBC) is challenging due to smoking-related comorbidities, treatment toxicity, and an increased risk of adverse health outcomes. Considering patient preferences prior to treatment is therefore crucial. Here, we aimed to identify the health outcome priorities of older patients with high-risk NMIBC (HR-NMIBC) or MIBC. Materials and MethodsPatients aged 70 years or older or at risk for frailty, diagnosed with HR-NMIBC or MIBC without distant metastases, were referred for a comprehensive geriatric assessment (CGA). The CGA consisted of an interview, physical examination, and several tests to examine physical, cognitive, functional, and social status. Quality of life was assessed using EQ5D and EORTC QLQ-C30 questionnaires. Health outcome priorities were discussed using the Outcome Prioritization Tool (OPT) and associations between health outcome priorities and CGA-determinants and quality of life were studied. ResultsOf 146 patients (14 HR-NMIBC, 132 MIBC), OPT data was available for 139. Life extension was most often prioritized (44%), closely followed by preserving independence (40%). Reducing pain (7%) and other symptoms (9%) were less often prioritized. Patients prioritizing life extension had fewer musculoskeletal problems than patients prioritizing reducing pain or other symptoms (p = 0.02). Patients at risk of or suffering from malnutrition more frequently selected reducing pain or other symptoms as their health outcome priority (p = 0.004). For all other CGA-determinants and quality of life, there were no significant differences between groups based on health outcome priorities. DiscussionIn older patients with HR-NMIBC and MIBC, life extension and preserving independence are the most common health outcomes priorities. CGA-determinants and quality of life are generally not associated with the prioritization of health outcomes. As health outcome priorities cannot be predicted by CGA-determinants or quality of life, it is crucial to discuss health outcome priorities with patients to promote shared decision-making.

Paradigm Shifts in Hodgkin Lymphoma Treatment: From Frontline Therapies to Relapsed Disease.

Combination chemotherapy with or without radiation has served as the primary therapeutic option for classic Hodgkin lymphoma (cHL), leading to durable remission in a majority of patients with early- and advanced-stage cHL. Patients with relapsed/refractory (RR) cHL could still be cured with salvage chemotherapy and autologous stem-cell transplantation. Brentuximab vedotin (BV) and the anti-PD-1-blocking antibodies, nivolumab and pembrolizumab, are highly effective treatments for cHL and have revolutionized the management of the disease. Recent studies incorporating BV and PD-1 blockade into salvage therapy for RR cHL and into frontline treatment regimens have changed the cHL treatment paradigm. The novel agents are also useful in the treatment of older patients who have poor outcomes with traditional therapy. This manuscript will review current strategies for approaching the management of previously untreated, RR, and challenging populations with cHL, including how to incorporate the novel agents.

Long-term outcomes of neoadjuvant treatment in older patients with HER2-positive breast cancer: Evidence from a single center in Mexico.

e12648 Background: The optimal approach to managing breast cancer (BC) in elderly women is still far from certain. These patients are often underrepresented in clinical trials, leaving the long-term effectiveness and safety aspects of treatment unclear. This study aimed to assess long-term survival outcomes of neoadjuvant treatment and cardiac toxicity in geriatric HER2-positive BC patients. Methods: Patients aged over 64, diagnosed with clinical stage IIA-IIIC HER2-positive BC between January 2007 and December 2022, were retrospectively reviewed. Patients were identified from Instituto Nacional de Cancerologia's Breast Cancer Unit database. Only those receiving neoadjuvant treatment were selected. Treatment information: left ventricular ejection fraction (LVEF) measurements and survival events were captured from medical electronic records. Descriptive statistics were used to report patient characteristics and treatment details. Event-free survival (EFS) and Overall Survival (OS) were evaluated with Kaplan-Meier. Cardiac toxicity was defined as a decrease in LVEF &gt;10% over baseline or &lt;50% during neoadjuvant therapy, and was compared between anthracycline-based and anthracycline-free regimens. Results: A total of 193 patients with an age greater than 64 and clinical stage IIA-IIIC HER2-Positive BC were identified from a database of 10.859 BC patients. From these, 87 patients received neoadjuvant treatment. As documented comorbidities prior to initiation of treatment, 54.0% of patients reported hypertension, 18.4% had diabetes, 81.6% were found with overweight or obesity, 12.6% were smokers, and 3.4% had a history of cardiovascular disease. The median age was 68, the median number of administered cycles was 8, and 88.5% of patients underwent surgery. The median follow-up was 9.25 years. Median EFS was 12.3 years, median OS was unreached, EFS-3yr was 76.3% and OS-3yr was 88.1%. Among patients who underwent surgery, 48.0% and 66.7% achieved a complete pathological response (ypT0/is ypN0) when treated with anthracycline-based and anthracycline-free regimes, respectively. The proportion of patients who developed cardiac toxicity during neoadjuvant treatment was 14.7%, all treated with anthracycline-based regimens. One patient under an anthracycline-based regime developed clinical heart failure. No cardiac toxicity was observed in patients treated with anthracycline-free regimens. Conclusions: Our findings show that, in this complex older population, long-term survival outcomes do not appear low. In addition, anthracycline-free regimens might represent a safer alternative from a cardiovascular perspective. Despite limitations of retrospective studies, this research addresses a long-standing gap in the representation of geriatric patients in clinical trials and contributes as a basis for improving neoadjuvant strategies.

Bioethics of over- and undertreatment in older adults with cancer.

9046 Background: Over-/undertreatment are pervasive in older adults with cancer, despite oncologists prescribing with best intentions. What “ought” to be prescribed with limited evidence creates challenges in adhering to the principles of bioethics: beneficence, nonmaleficence, justice, and respect for autonomy. Our objective for this study was to elucidate whether and how tensions among these ethical principles can contribute to over-/undertreatment in older patients. Methods: We designed a modified Delphi study, convening a panel of 13 experts in biomedical ethics (5 male, 8 female; 4 MD, 4 PhD, 2 MD/MA, 1 MD/PhD, 1 JD/MDiv, 1 DNP) from U.S. and Canadian institutions for three iterative rounds of data collection. In the first round—an electronic questionnaire—we presented definitions of overtreatment and undertreatment in older adults with cancer (DuMontier, J Clin Oncol, 2020) and asked questions delineating which ethical principles related to each definition, followed by questions regarding how over-/undertreatment might occur from conflicts among different ethical principles. Consensus for each question was defined as ≥75% of experts answering “agree” or “strongly agree”. The second round consisted of a virtual synchronous focus group of 9 of the panel experts led by a qualitative researcher to review round one results and discuss questions that did not reach consensus, followed by a second questionnaire including these questions. Results: After the first round, experts reached consensus that bioethical principles applied to over-/undertreatment in older adults with cancer. Specifically, 92% felt that overtreatment can occur when oncologists overemphasize beneficence that values the potential benefit of cancer treatments, while underemphasizing non-maleficence with respect to treatment adverse effects. Moreover, 77% felt that overtreatment can also occur when oncologists prioritize patient autonomy (preference to be treated) over non-maleficence (oncologists' concerns that treatment harms outweigh benefits). 84% felt that undertreatment can occur due to a lack of justice in equitable consideration of cancer treatments that could provide similar benefits in older adults as they would in younger adults. Moreover, 77% felt that undertreatment can occur when oncologists underemphasize patient autonomy, failing to consider patient preferences regarding which benefits to pursue and risks to take. Data collection for the second questionnaire and qualitative analysis of the focus group are underway. Conclusions: Our findings suggest that tension in ethical principles can lead to over- and undertreatment in older adults with cancer. The “right” treatment in older patients in the context of limited evidence is not simply one that aims to aggressively target their cancer, but that balances both benefits and harms in light of the whole patient and their preferences, while not restricting therapies based on age alone.

Sarcopenia in older patients with idiopathic normal pressure hydrocephalus: an observational study from a single geriatric clinic in Turkey.

Idiopathic normal pressure hydrocephalus (iNPH), a classical triad of gait abnormality, cognitive disturbance, and urinary incontinence, increases in prevalence with aging. Sarcopenia is also characterized by low muscle strength and mass, contributing to gait difficulty. Gait abnormality and lower physical activity also lead to the development of sarcopenia. Therefore, this study aims to investigate the relationship between sarcopenia and iNPH. A total of 327 participants were included in this retrospective cross-sectional study. Demographic and clinical characteristics, including age, sex, comorbidity index, number of medications, recurrent falls in the last year, laboratory findings and comprehensive geriatric assessment (CGA) parameters were recorded. Sarcopenia was defined according to the EGWSOP2 criteria. The relationship between sarcopenia and iNPH was assessed with regression analysis. There were 51 participants with iNPH, 49% female, mean age 78years (SD 5.7) and 276 control participants, 74% female, mean age 72years (SD 6.1). The sarcopenia rates in patients with iNPH and controls were 19.6% and 2.5%, respectively (p < 0.01). The odds of probable sarcopenia were 3.89 times, and the slow gait speed was 8.47 times higher in iNPH patients than in controls after adjusting for age, sex, and the other confounders. The Mini-Mental State Examination score (p = 0.042, OR = 0.869 with 95% CI:0.759-0.995) was associated with probable sarcopenia among patients with iNPH. This study demonstrated that sarcopenia was common in older patients with iNPH, which seems to be closely associated with decreased muscle strength and slowed gait speed. Thus, considering the potential untoward effects of both diseases, it is important for physicians to evaluate sarcopenia routinely in the follow-up and treatment of older patients with iNPH.
