Background: Malnutrition is prevalent in elderly inpatients and is associated with various adverse outcomes during their hospital stay, but the diagnosis of malnutrition still lacks widely applicable criteria. This study aimed to investigate the association of malnutrition diagnosed with the SGA, ESPEN 2015, and GLIM criteria, respectively, with in-hospital complications in elderly patients. Method: Hospitalized patients over 65 years old who had been assessed with the SGA guideline for malnutrition at admission were retrospectively recruited from a large observational cohort study conducted in 34 level-A tertiary hospitals in 18 cities in China from June to September 2014. Malnutrition was then retrospectively diagnosed using the GLIM and ESPEN 2015 criteria, respectively, for comparison with the results of the SGA scale. The risk factors for malnutrition were analyzed using logistic regression, and the value of the three diagnostic criteria in predicting the in-hospital complications was subsequently explored using multivariate regression and the random forest machine learning algorithm. Results: A total of 2526 subjects who met the inclusion and exclusion criteria of the study were selected from the 7122 patients in the dataset, with an average age of 74.63 ± 7.12 years, 59.2% male, and 94.2% married. According to the GLIM, SGA, and ESPEN 2015 criteria, the detection rates of malnutrition were 37.8% (956 subjects), 32.8% (829 subjects), and 17.0% (429 subjects), respectively. The diagnostic consistency between the GLIM and the SGA criteria is better than that between the ESPEN 2015 and the SGA criteria (Kappa statistics, 0.890 vs. 0.590). Logistic regression showed that the risk of developing complications in the GLIM-defined malnutrition patients is 2.414 times higher than that of normal patients, higher than those of the ESPEN 2015 and SGA criteria (1.786 and 1.745 times, respectively). The random forest classifications show that the GLIM criteria have a higher ability to predict complications in these elderly patients than the SGA and ESPEN 2015 criteria with a mean decrease in accuracy of 12.929, 10.251, and 5.819, respectively, and a mean decrease in Gini of 2.055, 1.817, and 1.614, respectively. Conclusion: The prevalence of malnutrition diagnosed with the GLIM criteria is higher than that of the SGA and the ESPEN 2015 criteria. The GLIM criteria are better than the SGA and the ESPEN 2015 criteria for predicting in-hospital complications in elderly patients.

Literature concerning nutritional interventions in elderly patients with gastrointestinal cancer, with special reference to randomized clinical trials, has been critically reviewed. This segment of oncologic population was found to be penalized by a high prevalence of malnutrition and sarcopenia which translated in an increased rate of toxicity from chemotherapy, poor compliance with oncologic treatments, and, finally, with a poor prognosis. Attempts to reverse this condition included a potentiation of nutrients intake which should sequentially proceed through the use of dietary counseling and administration of standard or ω-3 fatty acid–enriched oral supplements to finally come to enteral or parenteral nutrition. Randomized clinical trials investigating the effects of simple dietary advice and use of standard oral supplements were disappointing as regards long-term compliance and results. Nutritional and clinical benefits were reported with the use of ω-3 fatty acid–enriched oral supplements and especially with long-term supplemental parenteral nutrition. Despite the general recommendation of the scientific community that emphasizes the use of the enteral route, whenever possible, for delivering the nutritional support, it appears from the literature that more consistent benefits can be achieved, especially in the long-term nutritional support, when an insufficient oral nutrition is partnered with intravenous nutrition.

To survey the difference of frailty prevalence in elderly inpatients amongdifferent wards; to compare the diagnostic performance of five frailty measurements (Clinical Frailty Scale [CFS], FRAIL, Fried, Edmonton, Frailty Index [FI]) in identifying frailty; and to explore the risk factors of frailty in elderly inpatients. This was a cross-sectional study including 1000 inpatients (mean age 75.2±6.7 years, 51.5% male; 542, 229, and 229 patients from cardiology, non-surgical, and surgical wards, respectively) in a tertiary hospital from September 2018 to February 2019. We applied the combined index to integrate the five frailty measurements mentioned above as the gold standard of frailty diagnosis. Multivariate logistic regression models were used to determine the independent risk factors of frailty. Frailty prevalence was 32.3% (Fried), 36.2% (CFS), 19.2% (FRAIL), 25.2% (Edmonton), 35.1% (FI) in all patients. The frailty was more common in non-surgical wards, regardless of the frailty assessment tools used (non-surgical wards: 27.5% to 51.5%; cardiology ward: 14.9% to 29.3%; surgical wards: 18.8% to 41.9%). CFS≥5 showed a sensitivity of 94.1% and a specificity of 85.2% for all patients. FI≥0.25 showed a sensitivity of 94.8% and a specificity of 87.0% for all patients. Age [odds ratio (OR) = 1.089, P<0.001], education level (OR = 0.782, P=0.001), heart rate (OR = 1.025, P<0.001), albumin (OR = 0.911, P=0.002), log D-dimer (OR = 2.940, P<0.001), ≥5 comorbidities (OR = 2.164, P=0.002), and ≥5 medications (OR = 2.819, P<0.001) were independently associated with frailty in all participants. Frailty is common among elderly inpatients, especially in non-surgical wards. CFS is a preferred screening tool and FI may be an optimal assessment tool. Old age, low educational level, fast heart rate, low albumin, high D-dimer, ≥5 comorbidities, and polypharmacy are independent risk factors of frailty in elderly hospitalized patients.

Topical lidocaine is commonly used to blunt hemodynamic responses to laryngoscopy and intubation. In elderly patients, however, its specific effect on reducing the required dose of sufentanil during induction remains unquantified. We aimed to determine whether pre-intubation lidocaine spray lowers the 95% effective dose (ED ) of sufentanil needed to attenuate this response. Eighty patients aged 65-80 years undergoing elective surgery under general anesthesia with tracheal intubation were enrolled in this randomized, double-blind, dose-finding study. Prior to intubation, patients were randomly assigned to receive an oropharyngeal and laryngeal spray of either 2% lidocaine (Group A) or normal saline (Group B). The induction dose of sufentanil for each subsequent patient was adjusted based on the previous patient's hemodynamic response, following a biased-coin up-and-down sequential allocation method with a step size of 0.05 µg·kg . A positive response was defined as MAP or HR remaining within 30% of baseline values within 3 min after intubation. The ED and its 95% confidence interval (CI) were estimated using isotonic regression and bootstrapping methods. Extubation time, severity of coughing at emergence, postoperative sore throat (POST), and adverse events, were recorded. The estimated ED of sufentanil was 0.419 µg·kg (95% CI 0.348-0.437) in Group A and 0.530 µg·kg (95% CI 0.400-0.542) in Group B. Bootstrap analysis yielded a between-group difference (ΔED ) of 0.111 μg·kg (95% CI 0.001-0.188), indicating a statistically significant difference. Cough during emergence was more severe in Group B (P < 0.05). No statistically significant differences were observed between groups in extubation time, POST, or other adverse events. In elderly patients, topical airway lidocaine spray reduces the ED of sufentanil to 0.419 µg·kg for blunting hemodynamic responses to tracheal intubation. This adjunctive intervention decreases sufentanil requirements and improves emergence quality by reducing the severity of coughing in this elderly population.

Background: Idiopathic pulmonary fibrosis (IPF) is the most common and severe form of idiopathic interstitial pneumonia, and its prevalence increases with age. In the era of pre-antifibrotic agents, the median survival time of Japanese patients with IPF is 35 months, with a 5-year survival rate in western countries ranging from 20% to 40%. The prevalence of IPF is highest in elderly patients aged ≥75 years; however, the efficacy and safety of long-term use of pirfenidone and/or nintedanib are not fully understood. Objective: This study aimed to determine the efficacy and safety of the sole use of antifibrotic agents (pirfenidone or nintendanib) for IPF in the elderly. Method: We retrospectively reviewed patients with IPF who were diagnosed and treated with either pirfenidone or nintedanib in our hospital between 2008 and 2019. We excluded patients with the subsequent use of both antifibrotic agents. We examined the survival probability and frequency of acute exacerbation, with focus on long-term use (≥1 year), elderly patients (≥75 years of age), and disease severity. Results: We identified 91 patients with IPF (male to female ratio: 63 to 28, age 42 to 90 years). The numbers of patients with disease severity classified by JRS (I/II/III/IV) and GAP stage (I/II/III) were (38/6/17/20) and (39/36/6), respectively. The survival probabilities were comparable between the elderly (n = 46) and non-elderly groups (n = 45, p = 0.877). After the initiation of antifibrotic agents, the cumulative incidence ratio of acute exacerbation of IPF was significantly lower in the early stage (GAP stage I, n = 20) than in the progressive stage of disease (GAP stages II and III, n = 20, p = 0.028). A similar trend was noted in the JRS disease severity classification (I, II vs. III, IV) (n = 27 vs. n = 13, p = 0.072). In the long-term treatment (≥1 year) group (n = 40), the survival probabilities at 2 and 5 years after treatment initiation were 89.0% and 52.4%, respectively, which did not reach the median survival rate. Conclusions: Even in elderly patients (≥75 years of age), antifibrotic agents demonstrated positive effects on survival probability and the frequency of acute exacerbation. These positive effects would be improved for earlier JRS/GAP stages or long-term use.

Orthostatic hypotension (OH) is a common autonomic disorder. This study aimed to investigate the influencing factors and hemodynamic mechanisms of initial and sustained OH in middle‐aged and elderly patients. The authors analyzed the clinical characteristics and hemodynamic variables of patients aged ≥ 50 years according to the various forms of OH, diagnosed by an active orthostatic test using the CNAP monitor. The study included 473 participants; 119 (25.2%) patients had initial (54, 45.4%) or sustained (65, 54.6%) OH. Age, comorbidities, or medications did not differ significantly between the initial OH and non‐OH groups. Sustained OH was associated with age and diabetes (p = .003 and p = .015, respectively). Hemodynamic analysis revealed higher cardiac output (CO) in the sustained OH group within 15 s than in the non‐OH and initial OH groups (both p < .001); no difference in CO was observed between the initial OH and non‐OH groups. The systemic vascular resistance (SVR) in both initial OH and sustained OH groups within 15 s was lower than that in the non‐OH group (both p < .001). No differences in SVR at 3 min were observed between the initial OH and non‐OH groups. The SVR at 3 min in the sustained OH group was significantly lower than in non‐OH and initial OH groups (both p < .001). Age and diabetes emerged as the independent risk factors associated with sustained OH. Initial OH is associated with a mismatch of increase in CO and decrease in SVR. Sustained OH is mainly associated with sustained inadequate adjustment in SVR.

Background Intertrochanteric fracture is a common fracture suffered by elderly patients. Total hip arthroplasty (THA) is regarded as a salvage operation to restore hip joint function after fixation failure, which remains somewhat controversial due to some clinical potential issues. Methods 18 elderly patients (average age 70.3 years) each with intertrochanteric fracture fixation failure treated with THA between September 2013 and October 2016 were retrospectively analyzed. Internal fixation treatments involved 5 patients who had received proximal femoral nail anti-rotation, 7 who received locking proximal femur plates and 6 who received dynamic hip screws. All patients were treated with THA using biological acetabular prosthesis and hip arthroplasty (HA) coating skillet femoral prosthesis, with the greater trochanter fixed using wire or steel when necessary. Patients’ Harris scores pre- and post-treatment, SF-36 Health Questionnaire score and digital radiology (DR) were used for joint prostheses initial stability and survival evaluation. Results 15 patients completed follow-up periods ranging between 19 and 54 months (mean 26.2 months; 1 patient died from a pulmonary embolism, 1 patient died from pulmonary heart disease 1 year after surgery and 1 patient withdrew for personal reasons). There were no joint infections, periprosthetic fractures or dislocations. The average Harris score increased significantly, from 32.68 ± 12.04 points before surgery to 91.08 ± 5.9 points at 24 months post-treatment. SF-36 scores were significantly increased. Conclusion THA as salvage treatment for failed internal fixation of intertrochanteric femoral fractures in elderly patients significantly reduced hip pain and restored joint function, and early clinical outcomes were satisfactory.

Endoscopic submucosal dissection (ESD) is a safe and minimally invasive method for the treatment of early gastric cancer (EGC). However, whether ESD for EGC is also safe and feasible in patients aged ≥85 years is unclear. The patients enrolled in this study were divided into three groups: age ≥85 years (44 patients, 49 lesions), age 65–84 years (624 patients, 687 lesions), and age ≤64 years (162 patients, 174 lesions). We evaluated the incidence of adverse events (AEs) and overall survival (OS) and disease-specific survival (DSS). We analyzed the factors that had a significant impact on the prognosis of patients aged ≥85 years. No significant differences were found in the incidence of AEs among the three groups (p = 0.612). The OS was significantly lower in patients aged ≥85 years (p < 0.001). Conversely, DSS was not significantly worse in patients aged ≥85 years (p = 0.100). The poor Geriatric Nutritional Risk Index correlated with poor prognosis in patients aged ≥85 years (p < 0.001). ESD is a safe and valid treatment for EGC in patients aged ≥85 years. However, the indications should be carefully decided because it is difficult to estimate the survival contribution of ESD for EGC in patients aged ≥85 years, especially in those with poor nutritional status.

Despite evident lifestyle changes due to measures against the coronavirus disease 2019 (COVID-19) outbreak, few reports focus on the effects of eating-behavior changes on the nutritional status of elderly patients undergoing hemodialysis (HD). Thus, we examined dry-weight reduction, the simplest indicator of malnutrition among patients undergoing dialysis, and its association with the discontinuation of cafeteria services at a dialysis facility as per COVID-19 measures. This retrospective study included elderly patients (aged ≥ 65 years) undergoing HD at the Nagasaki Renal Center between December 2020 and October 2021. We collected nutrition-related data and patient characteristics and evaluated the association between the service discontinuation and dry-weight reduction 10 months after the discontinuation using multivariable logistic regression. This study included 204 patients, 79 of which were cafeteria users. During the observation period, cafeteria users showed significant dry-weight reduction; however, this was not observed among non-users. Multivariable logistic regression analysis indicated a close association between dry-weight reduction and the service discontinuation. That is, the dietary services cancelation caused dry-weight reduction in patients who relied on the cafeteria. As elderly patients undergoing HD are vulnerable to changes in their eating environment, alternative nutritional management methods need to be considered.

Background Femoral neck fractures (FNFs), which are common in the older population, are associated with high mortality and morbidity. Some 20% of FNFs are undisplaced (uFNFs). The routine surgical procedure for uFNFs is internal fixation (IF) with 2–3 screws/pins with a reported reoperation rate in older patients (age ≥ 75 years) of up to 21%. The reoperation rate for hemiarthroplasties for displaced fractures is lower than for undisplaced fractures operated with IF. This study will aim to determine whether the outcome for older patients with an uFNF can be improved by replacing the hip instead of preserving it. Methods A national multicentre, register-based, randomised controlled trial (rRCT) will be conducted. For this trial, 1440 patients, ≥75 years with an acute uFNF, will be allocated. Eligible patients will be identified by the Swedish Fracture Register (SFR) platform, which will notify the admitting orthopaedic surgeon of eligibility. After informed consent has been given and documented, patients will be randomised to either IF (control group) or arthroplasty (intervention group) within the SFR platform. Injury mechanism, fracture classification, date of injury, and type of treatment are registered in the SFR. Type and brand of arthroplasty, surgical approach, and fixation are obtained from the Swedish Hip Arthroplasty Register (SHAR). The study cohort from the SFR will be cross-checked with the National Patient Register and the SHAR for outcome variables at 2, 5, and 10 years. The primary outcome will be a composite variable comprising reoperation rate and mortality at 2 years postoperatively. Secondary endpoints will include reoperation rate and mortality as stand-alone variables. In addition, secondary endpoints will be patient-reported outcomes as measured by the Short Musculoskeletal Functional Assessment questionnaire at 1 year postoperatively as routinely collected within the SFR. Further secondary endpoints will include the occurrence of adverse events such as pneumonia, stroke or myocardial infarction and evaluation of the external validity of the study. Discussion This large, multicentre, register-based randomised controlled trial could potentially shift the treatment of uFNFs in older patients towards primary hip arthroplasty in order to improve the outcome. Trial registration The trial is registered at www.clinicaltrials.gov ( NCT03966716 ); May 29, 2019.
