RESUMEN
Background and Objectives: Changes in activities of daily living (ADL) and quality of life (QOL) of patients with bone metastasis who underwent surgical treatment through Bone Metastasis Cancer Boards (BMCBs), a recent multidisciplinary approach for managing bone metastases, have been reported; however, no reports exist on patients who undergo conservative treatment. In this study, we aimed to evaluate these patients' ADL and QOL and examine the factors influencing changes in these parameters. Materials and Methods: We retrospectively reviewed 200 patients with bone metastases who underwent conservative therapy through BMCBs between 2013 and 2021. A reassessment was conducted within 2-8 weeks after the initial assessment. Patients' background and changes in performance status (PS), Barthel Index (BI), EuroQol five-dimension (EQ-5D) scores, and Numerical Rating Scale (NRS) scores were initially assessed. Furthermore, we categorized patients into two groups based on improvements or deteriorations in ADL and QOL and performed comparative analyses. Results: Significant improvements in EQ-5D (0.57 ± 0.02 versus [vs.] 0.64 ± 0.02), NRS max (5.21 ± 0.24 vs. 3.56 ± 0.21), and NRS average (2.98 ± 0.18 vs. 1.85 ± 0.13) scores were observed between the initial assessment and reassessment (all p < 0.001). PS (1.84 ± 0.08 vs. 1.72 ± 0.08) and BI (83.15 ± 1.68 vs. 84.42 ± 1.73) also showed improvements (p = 0.06, and 0.054, respectively). In addition, spinal cord paralysis (odds ratio [OR]: 3.69, p = 0.049; OR: 8.42, p < 0.001), chemotherapy (OR: 0.43, p = 0.02; OR: 0.25, p = 0.007), and NRS average scores (OR: 0.38, p = 0.02; OR: 0.14, p < 0.001) were independent factors associated with ADL and QOL. Conclusions: Patients with bone metastases who underwent conservative treatment through BMCBs exhibited an increase in QOL without a decline in ADL. The presence of spinal cord paralysis, absence of chemotherapy, and poor pain control were associated with a higher risk of deterioration in ADL and QOL.

Objective: The incidence of postoperative complications, including dysphagia, increases as the population undergoing cardiovascular surgery ages. This study aimed to explore the potential of maximum phonation time (MPT) as a simple tool for predicting postextubation dysphagia (PED) and major adverse cardiac and cerebrovascular events (MACCEs). Methods: This retrospective study included 442 patients who underwent elective cardiac surgery at a university hospital. MPT was measured before surgery, and patients were stratified into 2 groups based on normal and abnormal MPTs. Postoperative complications, including PED and MACCEs, were also investigated. Swallowing status was assessed using the Food Intake Level Scale. Results: MPT predicted PED with prevalence of 11.0% and 18.0% in the normal and abnormal MPT groups, respectively (P = .01). During the follow-up period, MACCEs developed in 17.0% of patients. Frailty, European System for Cardiac Operative Risk Evaluation II score, PED, and MPT were markedly associated with MACCEs (adjusted hazard ratios: 2.25, 1.08, 1.96, and 0.96, respectively). Mediation analysis revealed that MPT positively influenced PED and MACCEs, whereas PED positively influenced MACCEs. The trend in restricted cubic spline analysis indicated that the hazard ratio for MACCEs increased sharply when MPT was <10 seconds. Conclusions: These findings underscore the potential of MPT as a valuable tool in the preoperative assessment and management of patients undergoing cardiac surgery. By incorporating MPT into routine preoperative evaluations, clinicians can identify patients at a higher risk of PED and MACCEs, allowing for targeted interventions and closer postoperative monitoring. This may improve patient outcomes and reduce the health care costs associated with these complications.
RESUMEN
BACKGROUND/OBJECTIVE: The level of physical activity in the daily lives of cancer survivors following hematopoietic stem cell transplantation (HSCT) is crucial for maintaining their physical and mental health. Considering that life space mobility (LSM) may limit physical activity, maintaining and expanding LSM is particularly essential for post-HSCT survivors. This study aimed to identify factors influencing LSM in post-HSCT survivors. METHODS: Thirty cancer survivors after HSCT (14 women, mean age 52.0 ± 12.3 years, 196-3017 days post-HSCT) were included in this cross-sectional study. The assessment encompassed patient characteristics, employment status, life space (Life Space Assessment; LSA), physical function (handgrip strength, isometric knee extension strength, 5 chair standing test, walking speed), depression (Self-rating Depression Scale; SDS), fatigue (Cancer Fatigue Scale), and neighborhood walkability (Walk Score®). The association between LSA and each factor was compared by correlation analysis. Subsequently, multiple regression analysis was conducted, with LSA as the dependent variable and independent variables being outcome measures exhibiting a significant correlation with LSA. RESULTS: Variables significantly correlated with LSA included SDS (r =-0.65, p < .01), employment status (r=-0.60, p < .01), handgrip strength (r = 0.43, p = .02), and isometric knee extension strength (r = 0.40, p = .03). Results of multiple regression analysis show that SDS (ß = -0.53, p < .01), employment status (ß = 0.48, p < .01), and isometric knee extension strength (ß = 0.27, p = .02) were significantly associated with LSA (R2 = 0.74). CONCLUSION: Depression, employment status, and isometric knee extension strength were identified as factors related to LSM in post-HSCT survivors.

Background: Psychological readiness to return to sports (RTS) has been associated with second anterior cruciate ligament (ACL) injury. However, this relationship is controversial because covariates such as anatomic and knee function characteristics have not been adequately considered. Purpose/Hypothesis: To investigate whether psychological readiness in the early postoperative period can predict the occurrence of a second ACL injury within 24 months after primary ACL reconstruction (ACLR) using propensity score analysis. It was hypothesized that patients with high ACL-RSI after injury (ACL-RSI) scores at 3 months postoperatively would have a second ACL injury within the projected postoperative period. Study Design: Cohort study; Level of evidence, 3. Methods: Included were 169 patients who underwent primary ACLR using hamstring tendon autografts between November 2017 and July 2021 and also underwent knee functional assessments at 3 months postoperatively. The ACL-RSI scale was used to assess psychological readiness for RTS. A second ACL injury was defined if ipsilateral or contralateral ACL injury was confirmed by examination within 24 months postoperatively. Based on a previous study showing that 65 was the highest cutoff value for the ACL-RSI score for RTS, we classified patients into 2 groups: those with high ACL-RSI scores (≥65; group H) and those with low ACL-RSI scores (<65; group L). We generated 1-to-1 matched pairs using propensity score analysis and used log-rank testing to compare the rate of second ACL injury between the 2 groups. Results: More patients returned to any sports activities within 12 months in group H than in group L (90% vs 73%; P = .03). A second ACL injury within 24 months postoperatively was identified in 7% of patients (13/169). The rate of second ACL injury was significantly higher in group H than in group L (17.6% vs 3.4%; P = .001). In 43 matched pairs extracted using propensity scoring, the rate of second ACL injury was also higher in group H than in group L (18.6% vs 4.7%; P = .04). Conclusion: Patients with a higher ACL-RSI score at 3 months exhibited a significantly higher incidence of second ACL injury within 24 months after primary ACLR.
RESUMEN
OBJECTIVE: To elucidate the patient characteristics and outcomes of emergency surgery for spinal metastases and identify risk factors for emergency surgery. METHODS: We prospectively analyzed 216 patients with spinal metastases who underwent palliative surgery from 2015 to 2020. The Eastern Cooperative Oncology Group performance status, Barthel index, EuroQol-5 dimension (EQ5D), and neurological function were assessed at surgery and at 1, 3, and 6 months postoperatively. Multivariate analysis was performed to identify risk factors for emergency surgery. RESULTS: In total, 146 patients underwent nonemergency surgery and 70 patients underwent emergency surgery within 48 hours of diagnosis of a surgical indication. After propensity score matching, we compared 61 patients each who underwent nonemergency and emergency surgery. Regardless of matching, the median performance status and the mean Barthel index and EQ5D score showed a tendency toward worse outcomes in the emergency than nonemergency group both preoperatively and 1 month postoperatively, although the surgery greatly improved these values in both groups. The median survival time tended to be shorter in the emergency than nonemergency group. The multivariate analysis showed that lesions located at T3-10 (p = 0.002; odds ratio [OR], 2.92; 95% confidence interval [CI], 1.48-5.75) and Frankel grades A-C (p < 0.001; OR, 4.91; 95% CI, 2.45-9.86) were independent risk factors for emergency surgery. CONCLUSION: Among patients with spinal metastases, preoperative and postoperative subjective health values and postoperative survival are poorer in emergency than nonemergency surgery. Close attention to patients with T3-10 metastases is required to avoid poor outcomes after emergency surgery.
RESUMEN
Objectives: The effectiveness of acute rehabilitation treatment for severe coronavirus disease 2019 (COVID-19) has not yet been established. This study examined the efficacy of treatment provided to patients with severe COVID-19 in an acute care facility. Methods: A total of 98 patients with severe COVID-19 requiring inpatient management in our intensive care unit (ICU) were included between December 2020 and October 2021. They were divided into two groups: those who received physiotherapy (PT group; n=44) and those who did not receive physiotherapy (non-PT group; n=54). Their backgrounds, clinical characteristics, and activities of daily life (ADL) at discharge were compared to examine factors that influenced the need for physiotherapy (PT). We also evaluated the effect of PT on ADL by comparing the Barthel Index (BI) before PT and at discharge. Results: The PT group patients were significantly older, had longer hospital and ICU stays, and used invasive mechanical ventilators (IMV) more frequently than those in the non-PT group. More patients in the non-PT group were able to walk at discharge than in the PT group. The PT group patients showed significant improvement in BI and ADL at discharge when compared with BI at the start of PT, regardless of whether an IMV was used. Conclusions: Older patients with severe COVID-19 with prolonged hospitalization or ICU stay or on an IMV are prone to a decline in ADL and may need to be considered for early PT.
RESUMEN
Background and Objectives: Bone metastasis cancer boards (BMCBs) focusing on the management of bone metastases have been gathering much attention. However, the association of BMCBs with spinal surgery in patients with spinal metastases remains unclear. In this retrospective single-center observational study, we aimed to clarify the effect of a BMCB on spinal metastasis treatment. Materials and Methods: We reviewed consecutive cases of posterior decompression and/or instrumentation surgery for metastatic spinal tumors from 2008 to 2019. The BMCB involved a team of specialists in orthopedics, rehabilitation medicine, radiation oncology, radiology, palliative supportive care, oncology, and hematology. We compared demographics, eastern cooperative oncology group performance status (ECOGPS), Barthel index (BI), number of overall versus emergency surgeries, and primary tumors between patients before (2008-2012) and after (2013-2019) BMCB establishment. Results: A total of 226 patients including 33 patients before BMCB started were enrolled; lung cancer was the most common primary tumor. After BMCB establishment, the mean patient age was 5 years older (p = 0.028), the mean operating time was 34 min shorter (p = 0.025), the mean hospital stay was 34.5 days shorter (p < 0.001), and the mean BI before surgery was 12 points higher (p = 0.049) than before. Moreover, the mean number of surgeries per year increased more than fourfold to 27.6 per year (p < 0.01) and emergency surgery rates decreased from 48.5% to 29.0% (p = 0.041). Patients with an unknown primary tumor before surgery decreased from 24.2% to 9.3% (p = 0.033). Postoperative deterioration rates from 1 to 6 months after surgery of ECOGPS and BI after BMCB started were lower than before (p = 0.045 and p = 0.027, respectively). Conclusion: The BMCB decreased the emergency surgery and unknown primary tumor rate despite an increase in the overall number of spinal surgeries. The BMCB also contributed to shorter operation times, shorter hospital stays, and lower postoperative deterioration rates of ECOGPS and BI.

Purpose: To achieve a better patient experience with self-injection, an assessment of potential demographic, physical, and psychological barriers is necessary. The aim of this study was to examine the demographic, physical, and psychological characteristics associated with the experiences of self-injection in patients with rheumatoid arthritis (RA). Patients and Methods: In this study, overall patient experience with subcutaneous self-injection was assessed using the Self-Injection Assessment Questionnaire. Upper limb function was assessed using the three domains of the Health Assessment Questionnaire associated with upper extremity disability (dressing and grooming, eating, and grip). Structural equation modeling was used to estimate the association between the demographic and clinical characteristics of patients with RA and their experiences with self-injection in the theoretical model. Results: Data from 83 patients with RA were analyzed. Compared with younger patients, elderly patients were more likely to experience lower self-confidence, self-image, and ease of use. Female patients had lower ease of use than male patients. In terms of upper limb function, patients with more difficulty in performing activities of daily living were more likely to have a lower self-image. Self-injection perceptions before learning the method of injection, such as fear of needles and anxiety about self-injection, were associated with post-injection feelings, injection site reactions, self-confidence, and ease of use. Conclusion: To optimize patients' experiences with self-injection, healthcare workers should assess each patient's age, sex, upper limb function, and pre-self-injection perceptions as demographic, physical, and psychological barriers.
RESUMEN
BACKGROUND: In Japan, there are very few cases of deceased donor liver transplantation (DDLT) and even fewer studies on the effects of DDLT on sarcopenia. This study examined the changes in skeletal muscle mass and quality in DDLT, the factors related to these changes, and survival rates. METHODS: Using computed tomography (CT), we retrospectively measured L3 skeletal muscle index (L3SMI) and intramuscular adipose tissue content (IMAC) at admission, discharge, and 1-year post-DDLT in 23 patients with DDLT from our hospital between 2011 and 2020. We investigated the relationships between changes in L3SMI and IMAC associated with DDLT and between various admission factors and survival. RESULTS: Patients with DDLT showed significant decreases in L3SMI during hospitalization (P < .05). Although L3SMI tended to increase postdischarge, in 11 (73%) cases, it was lower at 1-year post-DDLT than that on admission. Moreover, decreases in L3SMI during hospitalization were correlated to L3SMI on admission (r = 0.475, P < 0.05). Intramuscular adipose tissue content increased from admission to discharge and decreased 1-year post-DDLT. Admission L3SMI and IMAC were not significantly correlated with survival. CONCLUSIONS: This study suggests that the skeletal muscle mass of DDLT patients decreased during hospitalization and showed a slight tendency to improve after discharge, but the decrease tended to be prolonged. In addition, patients with higher skeletal muscle mass at admission tended to lose more skeletal muscle mass during hospitalization. Deceased donor liver transplantation was identified as a potential contributor to improved muscle quality, whereas skeletal muscle mass and quality on admission did not affect post-DDLT survival.

The number of advanced-age patients with spinal metastases is rising. This study was performed to clarify the characteristics and surgical outcomes of spinal metastases in advanced-age patients. We prospectively analyzed 216 patients with spinal metastases from 2015 to 2020 and divided them into three age groups: <70 years (n = 119), 70-79 years (n = 73), and ≥80 years (n = 24). Although there were no significant intergroup differences in preoperative characteristics and surgery-related factors except for age, patients aged ≥80 years tended to have a worse performance status (PS), Barthel index, and EuroQol-5 dimension (EQ-5D) before and after surgery than the other two groups. Although the median PS, mean Barthel index and mean EQ-5D greatly improved postoperatively in each group, the median PS and mean Barthel index at 6 months and the mean EQ-5D at 1 month postoperatively were significantly poorer in the ≥80-year group than the 70-79-year group. The rates of postoperative complications and re-deterioration of the EQ-5D were significantly higher in the oldest group than in the other two groups. Although surgery for spinal metastases improved the PS, Barthel index, and EQ-5D regardless of age, clinicians should be aware of the poorer outcomes and higher complication rates in advanced-age patients.
RESUMEN
PURPOSE: This study compared the predictive ability of each independent predictor with that of a combination of predictors for quadriceps strength recovery one year after anterior cruciate ligament (ACL) reconstruction. METHODS: Patients who underwent primary ACL reconstruction using hamstring autografts were enrolled. Quadriceps strength, hamstring strength, and anterior tibial translation were measured, and the limb symmetry index (LSI) of the quadriceps and the hamstrings was calculated preoperatively and one year after surgery. Patients were classified into two groups according to the LSI of the quadriceps strength at one year postoperatively (≥ 80% or < 80%). Multivariate logistic regression analysis identified the independent predictors of quadriceps strength recovery, and the cut-off value was calculated using the receiver operating characteristic curve. A model assessing predictive ability of the combination of independent predictors was created, and the area under the curve (AUC) for each independent predictor was calculated by using the receiver-operating characteristic curves and the DeLong method. RESULTS: Of the 646 patients, 414 (64.1%) had an LSI of at least 80% for quadriceps strength one year after surgery, and 232 patients (35.9%) had an LSI of < 80%. Age, sex, body mass index (BMI), preinjury sport level, and LSI of preoperative quadriceps strength were independently associated with quadriceps strength recovery one year after ACL reconstruction. The cut-off values were age: 22.5 years; sex: female; BMI: 24.3 kg/m2; preinjury sport level: no sport; and LSI of preoperative quadriceps strength: 63.3%. The AUC of the model assessing the predictive ability of the combination of age, sex, BMI, preinjury sport level, and LSI of preoperative quadriceps strength was significantly higher (0.73) than that of similar factors of preoperative quadriceps strength (AUC: 0.63, 0.53, 0.56, 0.61, and 0.68, p < 0.01, respectively). CONCLUSION: The combination of age, sex, BMI, preinjury sport level, and LSI of preoperative quadriceps strength had a superior predictive ability for quadriceps strength recovery at one year after ACL reconstruction than these predictors alone. Multiple factors, including patient characteristics and preoperative quadriceps strength, should be considered when planning rehabilitation programs to improve quadriceps strength recovery after ACL reconstruction. LEVEL OF EVIDENCE: III.

Objectives: Increased long-term impairment is common among intensive care unit (ICU) survivors. However, predictors of activities of daily living (ADL) in ICU survivors are poorly understood. We aimed to focus on the trajectory of physical function and explore the clinical variables that affect ADL at hospital discharge. Methods: We enrolled 411 patients admitted to the ICU from April 2018 to October 2020. Physical function was evaluated at ICU admission, ICU discharge, and hospital discharge. We assessed physical function (grip strength, arm and calf circumference, quadriceps thickness, and Barthel index). Patients were assigned to the high or low ADL group based on their Barthel index at discharge. Propensity score matching analysis was performed to minimize selection biases and differences in clinical characteristics. Results: After matching propensity scores, 114 of the 411 patients (aged 65±15 years) were evaluated. The high ADL group showed better physical function at ICU discharge and hospital discharge than the low ADL group. An overall decreasing trend in muscle mass was observed over time; the rates of decline were lower in the high ADL group than in the low ADL group. The cutoff values for relative changes in calf circumference and quadriceps thickness to predict high ADL were -7.89% (sensitivity: 77.8%, specificity: 55.6%) and -28.1% (sensitivity: 81.0%, specificity: 58.8%), respectively. Conclusions: The relative decreases in calf circumference and quadriceps thickness during hospitalization were lower in patients who maintained their ADL. Assessment of the trajectory of physical function can predict ADL status at hospital discharge among ICU survivors.
RESUMEN
Objectives: Measurement of skeletal muscle using ultrasonography (US) has received considerable attention as an alternative method of muscle assessment. However, intra- and inter-rater reliability remains controversial. Furthermore, there is no consensus regarding the relationship between muscle assessment using US and muscle mass or physical assessment. We aimed to verify the validity and reliability of muscle measurements using US and its relationships with muscle strength and physical assessment. Methods: The 22 participants were all healthy men. Quadriceps muscle thickness was measured by US by three different raters. Intraclass correlation coefficient (ICC) was used to assess inter- and intra-rater reliability. The maximum isokinetic strength of the quadriceps and handgrip strength were used as measures of lower and upper muscle strength, respectively. Leg muscle mass was assessed using the leg skeletal muscle index (SMI), measured by body impedance analysis, and calf circumference. Results: The intra-rater reliability was excellent which the ICC(1,1) ranges 0.957-0.993, and ICC(1,3) ranges 0.985-0.998. For inter-rater reliability, the values of 0.904 for ICC(2,1) and 0.966 for ICC(2,3) indicated excellent reliability. Leg SMI was significantly correlated with quadriceps thickness (r=0.36). Maximum isokinetic strength and handgrip strength showed weak but statistically significant correlations with quadriceps thickness (r=0.20, r=0.30, respectively). The correlation between quadriceps thickness and calf circumference was not statistically significant. Conclusions: Quadriceps muscle assessment using US is a valid and reliable technique for healthy individuals. Quadriceps muscle thickness was significantly positively correlated with upper and lower muscle strength and leg SMI. Muscle thickness assessment could replace full body muscle assessment in clinical settings.
RESUMEN
Background: Symptomatic spinal metastasis (SSM) decreases the activities of daily living (ADL) and quality of life of cancer patients. However, the risk factors for SSM onset remain unclear. This prospective cohort study aimed to statistically analyze the significant risk factors. Methods: From 2016 to 2018, 210 consecutive patients with spinal metastases were prospectively registered. Patients with SSM at the first consultation and those who were unable to be followed-up owing to poor general condition were excluded. The demographic factors (age, sex, primary cancer, performance status, and ADL), clinical factors (radiation therapy, chemotherapy, molecularly targeted drugs, and bone-modifying agents (BMAs)), and Spinal Neoplastic Instability Score (SINS) were evaluated. Multivariate analysis was performed to identify the risk factors for SSM onset. Furthermore, the threshold was calculated from the receiver operating characteristic curve using the Youden index. Results: Thirty-nine patients who presented with SSM at the first consultation and 43 patients who were unable to be followed-up owing to poor general condition were excluded. Finally, 128 asymptomatic patients were included. Thirty-seven patients (28.9%) developed SSM during the follow-up period. The total SINS (OR: 1.739; 95% CI: 1.345-2.250) was identified as the most significant factor. The cut-off value of the SINS was 9.5 (sensitivity: 67.6%; specificity: 83.5%). Twenty-five (62.5%) of the forty patients with a SINS ≥ 10 developed SSM within a mean of 5.5 months (95% CI: 1.17-9.83). Furthermore, all patients with a SINS ≥ 13 developed SSM (n = 5) within a mean of 1.37 months (95% CI: 0.0-3.01). Conclusions: This study identified the significant risk factors for SSM onset and the threshold of the SINS. If long-term survival is expected, patients with a SINS ≥ 10 should be considered for intervention to prevent SSM.
RESUMEN
BACKGROUND: In order to improve cancer care in Japan further, it is now required for orthopaedic surgeons to get actively involved in managing locomotive organs such as bones, muscles and nerves in cancer patients. In 2018, the Japanese Orthopaedic Association (JOA) conducted a questionnaire survey to investigate the current status of cancer treatment at the orthopaedic training facilities certified by the JOA. We analyzed the results of that questionnaire survey, focusing on the data from the core hospitals for cancer care (designated cancer hospitals), to clarify the involvement of orthopaedic surgeons in cancer treatment. MATERIALS AND METHODS: A nationwide survey was conducted in the orthopaedic training facilities certified by the JOA using an online questionnaire from March 15th to 31st, 2018. To clarify the involvement of orthopaedic surgeons in cancer treatment, we analyzed the results of that questionnaire survey, focusing on the data from the designated cancer hospitals in Japan. RESULTS: From the questionnaire survey, it became clear that 24% of the orthopaedic training facilities certiï¬ed by the JOA are designated cancer hospitals. There were significant differences concerning cancer treatment and the prospect of orthopaedic surgeons' involvement in the treatment for bone metastases between institutions classified according to number of both certified orthopaedic surgeons by the JOA and specialists for bone and soft tissue tumors. In addition, in 45% of the designated cancer hospitals, orthopaedic surgeons treated bone metastases that occur in cancer patients, but in the rest of the institutions, orthopaedic surgeons did not yet adequately respond. CONCLUSION: In order to further improve the locomotive function and quality of life (QOL) in cancer patients, it was seemed to be necessary that all medical professionals engaged in cancer treatment, including orthopaedic surgeons, recognize the importance of locomotive management for cancer patients. In addition, the results of this study suggested that the presence of more than six certified orthopaedic surgeons by the JOA, including one or more specialists for bone and soft tissue tumors, may be able to create an environment conducive to the involvement of orthopaedic surgeons in cancer treatment at the facility.

AIMS: Post-extubation dysphagia (PED), an often overlooked problem, is a common and serious complication associated with mortality and major morbidity after cardiovascular surgery. Dysphagia is considered an age-related disease, and evaluating its long-term effects is a pressing issue with rapidly progressing ageing worldwide. Therefore, we examined the effect of PED on functional status and long-term cardiovascular events in patients undergoing cardiovascular surgery. METHODS AND RESULTS: This single-centre, retrospective cohort study included 712 patients who underwent elective cardiovascular surgery and met the inclusion criteria. Patients were divided into PED and non-PED groups based on their post-operative swallowing status. The swallowing status was assessed using the Food Intake Level Scale. Functional status was evaluated as hospital-associated disability (HAD), defined as a decrease in activities of daily living after hospital discharge compared with preoperative values. The patients were subsequently followed up to detect major adverse cardiac and cerebrovascular events (MACCEs). Post-extubation dysphagia was present in 23% of the 712 patients and was independently associated with HAD (adjusted odds ratio, 2.70). Over a 3.5-year median follow-up period, MACCE occurred in 14.1% of patients. Multivariate Cox proportional hazard analysis revealed HAD to be independently associated with an increased risk of MACCE (adjusted hazard ratio, 1.85), although PED was not significantly associated with MACCE. CONCLUSION: Post-extubation dysphagia was an independent HAD predictor, with the odds of HAD occurrence being increased by 2.7-fold due to PED. Hospital-associated disability accompanied by PED is a powerful predictor of poor prognosis. Perioperative evaluation and management of the swallowing status, and appropriate therapeutic interventions, are warranted.

Background: Postextubation dysphagia (PED) is a serious postoperative complication following cardiovascular surgery that can lead to a worse prognosis. On the other hand, frailty is a prognostic factor in patients who undergo cardiac surgery. Objectives: This study investigated the effect of frailty status on PED and impact of PED on postoperative complications. Methods: This single-center retrospective cohort study included 644 consecutive patients who underwent elective cardiovascular surgery between May 1, 2014, and December 31, 2020; they were assigned to the PED or non-PED group based on postoperative swallowing status, and postoperative complications were investigated. Frailty status and physical functions, including walking speed, grip strength, Short Physical Performance Battery, and 6-minute walking distance, were preoperatively assessed; the frailty-status cutoff for predicting PED was determined from the receiver-operating characteristic curve. Results: In this study cohort (mean age 67.7 years), the overall PED prevalence was 14.8%; preoperative frailty had a significantly higher prevalence in the PED group (50.0%) than in the non-PED group (20.3%; P < 0.001). PED correlated with a higher incidence of postoperative pneumonia and prolonged intensive care unit or hospital stay (P < 0.05 for all). After adjustment for confounders, multiple regression analysis revealed that preoperative frailty was independently associated with PED (P < 0.001). Conclusions: PED occurred commonly after cardiovascular surgery and increased the risk of postoperative complications. Preoperative frailty was independently associated with PED. The 6-minute walking distance was the most powerful predictor of PED. Evaluation of preoperative frailty status is important for risk stratification and prevention of postoperative morbidity in patients undergoing surgery.
RESUMEN
Body mass index (BMI) distribution and its impact on cardiovascular disease (CVD) vary between Asian and western populations. The study aimed to reveal time-related trends in the prevalence of obesity and underweight and safe ranges of BMI in Japanese patients with CVD. We analyzed 5,020,464 records from the national Japanese Registry of All Cardiac and Vascular Diseases-Diagnosis Procedure Combination dataset over time (2012-2019) and evaluated BMI trends and the impact on in-hospital mortality for six acute CVDs: acute heart failure (AHF), acute myocardial infarction (AMI), acute aortic dissection (AAD), ischemic stroke (IS), intracerebral hemorrhage (ICH), and subarachnoid hemorrhage (SAH). Patients were categorized into five groups using the WHO Asian-BMI criteria: underweight (< 18.5 kg/m2), normal (18.5-22.9 kg/m2), overweight at risk (23.0-24.9 kg/m2), obese I (25.0-29.9 kg/m2), and obese II (≥ 30.0 kg/m2). Age was significantly and inversely related to high BMI for all diseases (P < 0.001). The proportion of BMI categories significantly altered over time; annual BMI trends showed a significant and gradual increase, except AAD. In adjusted mixed models, underweight was significantly associated with a high risk of in-hospital mortality in all CVD patients (AHF, OR 1.41, 95% CI 1.35-1.48, P < 0.001; AMI, OR 1.27, 95% CI 1.20-1.35, P < 0.001; AAD, OR 1.23, 95% CI 1.16-1.32, P < 0.001; IS, OR 1.45, 95% CI 1.41-1.50, P < 0.001; ICH, OR 1.18, 95% CI 1.13-1.22, P < 0.001; SAH, OR 1.17, 95% CI 1.10-1.26, P < 0.001). Moreover, obese I and II groups were significantly associated with a higher incidence of in-hospital mortality, except AHF and IS. Age was associated with in-hospital mortality for all BMI categories in six CVD patients. BMI increased annually in patients with six types of CVDs. Although underweight BMI was associated with high mortality rates, the impact of obesity on in-hospital mortality differs among CVD types.

The effect of spine surgery for symptomatic spinal metastases (SSM) on patient prognosis remains unclear. This study aimed to reveal the prognosis of patients with SSM after spine surgery. One hundred twenty-two patients with SSM were enrolled in this prospective cohort study. The patients who received chemotherapy after enrollment were excluded. The decision of surgery depended on patient's willingness; the final cohort comprised 31 and 24 patients in the surgery and non-surgery groups, respectively. The patients were evaluated by their performance status (PS), activities of daily living (ADL) and ambulatory status. Survival was evaluated by the Kaplan-Meier method. The PS, ADL and ambulation were significantly improved in the surgery group compared to non-surgery group. The median survival was significantly longer in the surgery group (5.17 months, 95% confidence interval (CI) 3.27 to 7.07) than in the non-surgery group (2.23 months, 95% CI 2.03 to 2.43; p = 0.003). Furthermore, the patients with a better PS, ADL and ambulatory status had a significantly longer survival. Surgery improved the PS, ADL, ambulation and survival of patients with SSM. In the management of SSM, spine surgery is not only palliative but may also prolong survival.
RESUMEN
In this study, we examined the proliferation capability and osteogenic and chondrogenic differentiation potential of non-hypertrophic nonunion cells (NHNCs), and the effect of Escherichia coli-derived BMP-2 (E-BMP-2) on them. We enrolled five patients with non-hypertrophic nonunion. NHNCs isolated from nonunion tissue sampled during surgery were cultured, passaged, counted every 14 days, and analyzed. NHNCs were homogenous fibroblastic adherent cells and long-lived through at least 10 passages, with a slight decline. The cells were consistently positive for mesenchymal stem cell-related markers CD73 and CD105, and negative for the hematopoietic markers CD14 and CD45. NHNCs could differentiate into osteoblast lineage cells; however, they did not have strong calcification or sufficient chondrogenic differentiation capability. E-BMP-2 did not affect the proliferative capability of the cells but improved their osteogenic differentiation capability by increasing alkaline phosphatase activity and upregulating the gene expression of osterix, bone sialoprotein, and osteocalcin. E-BMP-2 enhanced their chondrogenic differentiation capability by upregulating the gene expression of aggrecan and collagen type II. We showed, for the first time, that NHNCs have the capacity to differentiate into osteoblast-lineage cells, although the chondrogenic differentiation potential was poor. Local application of E-BMP-2 with preservation of nonunion tissue is a potential treatment option for non-hypertrophic nonunion.
