RESUMO
BACKGROUND: Working while receiving cancer treatment is challenging for patients, with considerable impact on their quality of life (QOL). However, there have been no reports on the factors that prevent employment in patients with bone metastases. This study aimed to investigate the employment status and factors impacting the continued employment of patients with bone metastases. METHODS: We analyzed clinical data from new patients consulting The University of Tokyo Hospital team for bone metastasis treatment between June 2015 and September 2017. Patients who were working at the time of cancer diagnosis (n = 124) completed four QOL questionnaires. Factors associated with work sustainability were identified via univariate analysis and a chi-squared test. Multivariate logistic regression analysis was used for significant variables. Relationships between employment and QOL scales were investigated using the Wilcoxon rank-sum test, with P < .05 considered as statistically significant. RESULTS: Among the 124 patients, only 45 (36.3%) were still working when the questionnaire was administered. Multivariate analysis revealed temporary employment, lytic or mixed bone metastases, and lower limb or acetabular metastasis, as significant factors hindering work sustainability. The QOL scores were high in the continued employment group. However, the relationship between employment status and pain remains unclear. CONCLUSIONS: Lytic or mixed bone metastases and the lower limb and acetabular metastasis were significantly associated with employment resignation. Mobility difficulties may prevent patients with bone metastases from sustaining employment. Collaboration between rehabilitation professionals, oncologists, and workplaces is imperative to address this problem.
RESUMO
BACKGROUND: The clinical characteristics, outcomes, and prognostic factors of adult embryonal rhabdomyosarcomas (ERMS) and alveolar rhabdomyosarcomas (ARMS), particularly the differences among adolescents/young adults (AYA), adults, and older adults, remain unclear. We assessed the clinicopathological features and survival outcomes of adult patients with ERMS and ARMS in Japan and to compare these features among AYA, adult, and older adult patients. METHODS: We retrospectively analyzed data from the Bone and Soft Tissue Tumor Registry of Japan and enrolled patients aged ≥15 years with ERMS and ARMS. Disease-specific overall survival (DOS) was estimated using the Kaplan-Meier method, and a Cox regression model was used to identify prognostic factors. RESULTS: Among 184 patients with ERMS and ARMS (median age, 27 years; interquartile range, 18-49 years), a high rate of distant and regional nodal metastases was initially observed in 65 (35%) and 66 (36%) cases, respectively. Older age and distant metastasis at first presentation were statistically poor prognostic factors, and histological subtype and site of tumor origin were not associated with DOS. In patients with localized ERMS and ARMS, older age and nodal metastasis were poor prognostic factors; the 5-year DOS rates of patients with and without nodal metastasis were 23% and 72%, respectively. CONCLUSIONS: Older patients with rhabdomyosarcoma had a dismal prognosis, and distant metastasis was a poor prognostic factor. The prognostic factors differed between adult and pediatric patients with rhabdomyosarcoma; biological analyses, such as genome analysis of adult rhabdomyosarcoma and clinical trials with pediatric oncologists, are needed to improve the prognosis of adult rhabdomyosarcoma.

BACKGROUND: This prospective multicenter study assessed the prevalence of myocardial injury in patients with COVID-19 using cardiac magnetic resonance imaging (CMR).MethodsâandâResults: We prospectively screened 505 patients with moderate to severe COVID-19 disease from 7 hospitals in Japan. Of these patients, 31 (mean [±SD] age 63.5±10.4 years, 23 [74%] male) suspected of myocardial injury, based on elevated serum troponin or B-type natriuretic peptide concentrations either upon admission or 3 months after discharge, underwent CMR 3 months after discharge. The primary endpoint was the presence of myocardial injury, defined by any of the following: (1) contrast enhancement in the left or right ventricle myocardium on late gadolinium enhancement CMR; (2) left or right ventricular dysfunction (defined as <50% and <45%, respectively); and (3) pericardial thickening on contrast enhancement. The mean (±SD) duration between diagnosis and CMR was 117±16 days. The primary endpoint was observed in 13 of 31 individuals (42%), with 8 (26%) satisfying the modified Lake Louise Criteria for the diagnosis of acute myocarditis. CONCLUSIONS: This study revealed a high incidence of myocardial injury identified by CMR in patients with moderate to severe COVID-19 and abnormal findings for cardiac biomarkers.

RESUMO
Malignant giant cell tumor of bone (GCTB) is identified by the presence of multinucleated giant cells, with an aggressive behavior and a high risk of metastasis, which has not been genetically characterized in detail. H3 histone family member 3A (H3F3A) gene mutations are highly recurrent and specific in GCTB. The present study analyzed the clinical information and genomic sequencing data of eight cases of malignant GCTB (out of 384 bone sarcoma samples) using an anonymized genomic database. There were 5 males and 3 females among the cases, with a median age of 33 years at the time of the initial diagnosis. H3F3A G34W and G34L mutations were detected in 3 patients and 1 patient, respectively. In 75% of cases without H3F3A mutation, mitogen-activated protein kinase (MAPK) signaling pathway gene alterations were found (KRAS single nucleotide variant, KRAS amplification, nuclear respiratory factor 1-BRAF fusion). Moreover, the collagen type I alpha 2 chain-ALK fusion was detected in remaining one case. The most frequent gene alterations were related to cell cycle regulators, including TP53, RB1, cyclin-dependent kinase inhibitor 2A/B and cyclin E1 (75%, 6 of 8 cases). On the whole, the present study discovered recurrent MAPK signaling gene alterations or other gene alterations in cases of malignant GCTB. Of note, two fusion genes should be carefully validated following the pathology re-review by sarcoma pathologists. These two fusion genes may be detected in resembling tumors, which contain giant cells, apart from malignant GCTB. The real-world data used herein provide a unique perspective on genomic alterations in clinicopathologically diagnosed malignant GCTB.
RESUMO
Background: Coronavirus disease 2019 (COVID-19) sequelae, also known as long COVID, can present with various symptoms. Among these symptoms, autonomic dysregulation, particularly postural orthostatic tachycardia syndrome (POTS), should be evaluated. However, previous studies on the treatment of POTS complicated by COVID-19 are lacking. Therefore, this study aimed to investigate the treatment course of long COVID complicated by POTS. Methods: The medical records of patients who complained of fatigue and met the criteria for POTS diagnosis were reviewed. We evaluated the treatment days, methods and changes in fatigue score, changes in heart rate on the Schellong test, and social situation at the first and last visits. Results: Thirty-two patients with long COVID complicated by POTS were followed up (16 males; median age: 28 years). The follow-up period was 159 days, and the interval between COVID-19 onset and initial hospital attendance was 97 days. Some patients responded to ß-blocker therapy. Many patients had psychiatric symptoms that required psychiatric intervention and selective serotonin reuptake inhibitor prescription. Changes in heart rate, performance status, and employment/education status improved from the first to the last visit. These outcomes were believed to be because of the effects of various treatment interventions and spontaneous improvements. Conclusions: Our study suggests that the condition of 94% of patients with POTS complicated by long COVID will improve within 159 days. Therefore, POTS evaluation should be considered when patients with long COVID complain of fatigue, and attention should be paid to psychological symptoms and the social context.
RESUMO
BACKGROUND: The geographical disparity in the pathophysiological pattern of coronary artery disease (CAD) among patients undergoing percutaneous coronary intervention (PCI) is unknown. OBJECTIVES: To elucidate the geographical variance in the pathophysiological characteristics of CAD. METHODS: Physiological indices derived from angiography-based fractional flow reserve pullbacks from patients with chronic coronary syndrome enrolled in the ASET Japan (n = 206) and ASET Brazil (n = 201) studies, which shared the same eligibility criteria, were analysed. The pathophysiological patterns of CAD were characterised using Murray law-based quantitative flow ratio (µQFR)-derived indices acquired from pre-PCI angiograms. The diffuseness of CAD was defined by the µQFR pullback pressure gradient index. RESULTS: Significant functional stenoses pre-PCI (µQFR ≤0.80) were more frequent in ASET Japan compared to ASET Brazil (89.9% vs. 67.5%, p < 0.001), as were rates of a post-PCI µQFR <0.91 (22.1% vs. 12.9%, p = 0.013). In the multivariable analysis, pre-procedural µQFR and diffuse disease were independent factors for predicting a post-PCI µQFR <0.91, which contributed to the different rates of post-PCI µQFR ≥0.91 between the studies. Among vessels with a post-PCI µQFR <0.91, a consistent diffuse pattern of CAD pre- and post-PCI occurred in 78.3% and 76.7% of patients in ASET Japan and Brazil, respectively; only 6.3% (Japan) and 10.0% (Brazil) of vessels had a major residual gradient. Independent risk factors for diffuse disease were diabetes mellitus in ASET Japan, and age and male gender in Brazil. CONCLUSIONS: There was geographic disparity in pre-procedural angiography-based pathophysiological characteristics. The combined pre-procedural physiological assessment of vessel µQFR and diffuseness of CAD may potentially identify patients who will benefit most from PCI.

BACKGROUND: Pleomorphic rhabdomyosarcoma is a rare sarcoma in adults. The clinical characteristics, outcomes and prognostic factors associated with pleomorphic rhabdomyosarcoma remain unclear. METHODS: We retrospectively analyzed data from the Bone and Soft Tissue Tumor Registry of Japan, and enrolled patients with pleomorphic rhabdomyosarcoma. Disease-specific overall survival, local recurrence-free survival and distant metastasis-free survival were estimated using the Kaplan-Meier method; Cox regression model was used to identify prognostic factors. RESULTS: In total, 182 patients with pleomorphic rhabdomyosarcoma were included. Median age was 63 (range 20-95) years. The lower extremity (48%) was the most frequent tumor origin site, while head and neck were rare (4%). A total of 43 patients (24%) had distant or regional nodal metastases at first presentation. In all cases, the 2-year and 5-year survival rates were 66.3% and 54.1%, respectively. Distant metastasis was a significant poor prognostic factor (Hazard ratio 6.65; 95% confidence intervals, 3.00-14.75, P < 0.0001), with median survival of such patients being 9.4 (95% confidence intervals: 5.3-12.2) months. In 134 localized cases, the 2-year and 5-year survival rates were 91.5% and 68.3%, respectively. Large tumor size and older age were associated with poorer prognosis. Through data from localized and locally curative cases extracted and adjusted by propensity score matching, we found that perioperative chemotherapy did not improve disease-specific overall survival, distant metastasis-free survival or local recurrence-free survival. CONCLUSIONS: Clinical characteristics and outcomes of pleomorphic rhabdomyosarcoma are similar to those of other high-grade soft tissue sarcomas. Pleomorphic rhabdomyosarcoma may be less chemosensitive, and a strategy other than the standard cytotoxic chemotherapy is required to improve its prognosis.

BACKGROUND: extended curettage is generally used to treat infiltrative bone tumours. However, the extent of the curettage performed in previous studies remains unclear. This study aimed to investigate the efficacy of extended curettage for bone tumour-induced osteomalacia. METHODS: we included 12 patients with tumour-induced osteomalacia who underwent extended curettage at our hospital between 2000 and 2022. Extended curettage was applied in cases where tumour resection could cause functional impairment or necessitate complex reconstruction. We investigated patients' clinical and oncological outcomes. RESULTS: patients had a mean age of 55 (24-81) years, and the median follow-up duration after surgery was 3.9 (1.0-14.0) years. The causative tumours were located in the pelvis and lumbar spine. Imaging revealed the tumours to be of the sclerotic, intertrabecular, lytic and mixed types. Intraoperative 3D fluoroscopy was used in 10 patients. Extended curettage with high-speed burring and adjuvant therapy with cauterization using an electric scalpel and ethanol resulted in a remission rate of 83%; no recurrence or metastasis was observed in cases of early postoperative biochemical remission. In cases where the causative tumour was at the lumbar spine and ischium close to the acetabulum, no postoperative biochemical remission was observed, and conservative treatment was continued. Except for one patient with a tumour in the lumbar spine, all patients could walk without a cane. CONCLUSIONS: extended curettage for bone tumour-induced osteomalacia is oncologically and functionally favourable, especially in cases where resection of the causative tumour could cause functional impairment or necessitate complex reconstruction.

BACKGROUND: Even terminal cancer patients desire to walk to the toilet by themselves until the very last day. This study aimed to describe the walking ability of patients with spinal metastases at the end-of-life stage and identify the factors affecting this ability. METHODS: Among 527 patients who first visited our multidisciplinary team for bone metastasis between 2013 and 2016, 56 patients who had spinal metastases with a Spinal Instability Neoplastic Score ≥7 and died during follow-up were included. We collected general clinical data, performance status, Frankel classification, epidural spinal cord compression scale and Spinal Instability Neoplastic Score at the first consultation. Patients' last day of walking and date of death were also examined. Univariate analyses (chi-squared tests) were performed to identify the factors that impacted walking ability 30 and 14 days before patients' death. RESULTS: A total of 56 patients were extracted, and 57.1% (32/56) and 32.7% (16/49) of patients were ambulatory 30 and 14 days before death, respectively. Their performance status (P = 0.0007), Frankel grade (P = 0.012) and epidural spinal cord compression grade (P = 0.006) at the first examination, and administration of bone modifying agents during follow-up period (P = 0.029) were significantly related to walking ability 30 days before death. Among ambulatory patients 30 days before death, those with Spinal Instability Neoplastic Score ≥10 (P = 0.005), especially with high scores of collapse (P = 0.002) and alignment (P = 0.002), were less likely to walk 14 days before death. The walking period in the last month of their life was significantly longer in patients with total Spinal Instability Neoplastic Score 7-9 (P = 0.009) and in patients without collapse (P = 0.040) by the Wilcoxon test. CONCLUSION: The progression of spinal metastasis, especially neurological deficit, at the initial consultation were associated with walking ability 30 days before death, and spinal stability might be crucial for preserving walking ability during the last month. Early diagnosis and implementation of appropriate bone management might be important for the end-of-life walking ability.

The safety and feasibility are still not well known for exercise-induced mitral regurgitation (MR). This study is aimed to assess and compare the hemodynamic and symptomatic changes in patients with significant secondary MR during exercise stress echocardiography (ESE) before and after transcatheter edge-to-edge repair (TEER). The study included a total of 15 patients with secondary MR who underwent ESE before and after TEER using the MitraClip system (Abbott, Abbott Park, IL, USA). Echocardiographic data of ESE were collected both before the procedure and during the follow-up visit at 3 months. During the one-year postoperative observation period, the rate of readmission due to heart failure was 13% (n = 2), with no recorded fatalities. Although no significant differences of ESE data were observed in exercise-induced pulmonary hypertension or cardiac output before and after the repair, the severity of MR was significantly improved after the procedure, both at rest (2 [2-3] vs. 1 [1-2], p = 0.0125) and during ESE (3 [3-3] vs. 1 [1-1], p < 0.0001). Furthermore, the New York Heart Association Functional Classification was improved (3 [3-3] vs. 1 [1-1], p < 0.0001) after treatment. For a supplemental analysis, MR during ESE was significantly improved not only in cases with atrial secondary MR but also in ventricular secondary MR. Transcatheter edge-to-edge repair for exercise-induced MR resulted in a significant improvement in postoperative MR severity and subjective symptoms. These results are novel, as they have not been extensively reported previously, particularly among Japanese patients.

BACKGROUND: The MitraClip G4 system is a new iteration of the transcatheter edge-to-edge repair system. We assessed the impact of the G4 system on routine practice and outcomes in secondary mitral regurgitation (2°MR).MethodsâandâResults: Consecutive patients with 2°MR treated with either the MitraClip G2 (n=89) or G4 (n=63) system between 2018 and 2021 were included. Baseline characteristics, procedures, and outcomes were compared. Inverse probability of treatment weighting and Cox regression were used to adjust for baseline differences. Baseline characteristics were similar, except for a lower surgical risk in the G4 group (Society of Thoracic Surgeons Predicted Risk of Mortality ≥8: 38.1% vs. 56.2%; P=0.03). In the G4 group, more patients had short (≤2 mm) coaptation length (83.7% vs. 54.0%; P<0.001) and fewer clips were used (17.5% vs. 36.0%; P=0.02). Acceptable MR reduction was observed in nearly all patients, with no difference between the G4 and G2 groups (100% vs. 97.8%, respectively; P=0.51). The G4 group had fewer patients with high transmitral gradients (>5mmHg; 3.3% vs. 13.6%; P=0.03). At 1 year, there was no significant difference between groups in the composite endpoint (death or heart failure rehospitalization) after baseline adjustment (10.5% vs. 20.2%; hazard ratio 0.39; 95% confidence interval 0.11-1.32; P=0.13). CONCLUSIONS: The G4 system achieved comparable device outcomes to the early-generation G2, despite treating more challenging 2°MR with fewer clips.

BACKGROUND: Landmark trials showed that invasive pressure measurement (Fractional Flow Reserve, FFR) was a better guide to coronary stenting than visual assessment. However, present-day interventionists have benefited from extensive research and personal experience of mapping anatomy to hemodynamics. AIMS: To determine if visual assessment of the angiogram performs as well as invasive measurement of coronary physiology. METHODS: 25 interventional cardiologists independently visually assessed the single vessel coronary disease of 200 randomized participants in The Objective Randomized Blinded Investigation with optimal medical Therapy of Angioplasty in stable angina trial (ORBITA). They gave a visual prediction of the FFR and Instantaneous Wave-free Ratio (iFR), denoted vFFR and viFR respectively. Each judged each lesion on 2 occasions, so that every lesion had 50 vFFR, and 50 viFR assessments. The group consensus visual estimates (vFFR-group and viFR-group) and individual cardiologists' visual estimates (vFFR-individual and viFR-individual) were tested alongside invasively measured FFR and iFR for their ability to predict the placebo-controlled reduction in stress echo ischemia with stenting. RESULTS: Placebo-controlled ischemia improvement with stenting was predicted by vFFR-group (p < 0.0001) and viFR-group (p < 0.0001), vFFR-individual (p < 0.0001) and viFR-individual (p < 0.0001). There were no significant differences between the predictive performance of the group visual estimates and their invasive counterparts: p = 0.53 for vFFR vs FFR and p = 0.56 for viFR vs iFR. CONCLUSION: Visual assessment of the angiogram by contemporary experts, provides significant additional information on the amount of ischaemia which can be relieved by placebo-controlled stenting in single vessel coronary artery disease.

BACKGROUND: Renal congestion is a potential prognostic factor in patients with heart failure and recently, assessment has become possible with intrarenal Doppler ultrasonography (IRD). The association between renal congestion assessed by IRD and outcomes after mitral transcatheter edge-to-edge repair (TEER) is unknown, so we aimed to clarify renal congestion and its prognostic implications in patients with mitral regurgitation (MR) who underwent TEER using MitraClip system.MethodsâandâResults: Patients with secondary MR who underwent TEER and were assessed for intrarenal venous flow (IRVF) by IRD were classified according to their IRVF pattern as continuous or discontinuous. Of the 105 patients included, 78 patients (74%) formed the continuous group and 27 (26%) were the discontinuous group. Kaplan-Meier analysis revealed significant prognostic power of the IRVF pattern for predicting the composite outcome of all-cause death and heart failure rehospitalization (log-rank P=0.0257). On multivariate Cox regression analysis, the composite endpoint was independently associated with the discontinuous IRVF pattern (hazard ratio, 3.240; 95% confidence interval, 1.300-8.076; P=0.012) adjusted using inverse probability of treatment weighting. CONCLUSIONS: IRVF patterns strongly correlated with clinical outcomes without changes in renal function. Thus, they may be useful for risk stratification after mitral TEER for patients with secondary MR.

BACKGROUND: Aortic stenosis (AS) and chronic kidney disease (CKD) can coexist. Repeat exposure to contrast media in patients undergoing transcatheter aortic valve implantation (TAVI) has latent mortality risks and increased risk for acute kidney injury. We aimed to assess our "zero-contrast TAVI" protocol for patients with advanced CKD. METHODS: Consecutive patients with severe AS who underwent TAVI at a single center registry were enrolled. Zero-contrast TAVI group included patients who underwent TAVI without contrast and who had an estimated glomerular filtration rate <30 mL/min/1.73 m2. Conventional TAVI group included patients who underwent the regular TAVI procedure. Patients using balloon-expandable valves via transfemoral approach were analyzed. Baseline clinical and procedural characteristics and clinical outcomes were compared between two groups. The primary outcome was early safety as defined by Valve Academic Research Consortium Criteria. Secondary outcomes included the presence of severe prosthesis-patient mismatch, moderate or greater perivalvular leakage, and requirement for new dialysis (within 3 months). RESULTS: A total of 520 patients were analyzed. Among these, 32 (6 %) underwent zero-contrast TAVI and 488 (94 %) conventional TAVI. In the zero-contrast TAVI group, 12 patients (37.5 %) had to use 20.7 (11.0-31.2) mL of contrast media. There were no significant differences in the primary and secondary outcomes between zero-contrast TAVI and conventional TAVI groups (78.1 % vs. 86.8 %, P = 0.184 and 9.4 % vs. 8.1 %, P = 0.738 for the primary and secondary outcomes, respectively). CONCLUSIONS: Zero-contrast TAVI is feasible, safe, and effective in patients with AS and stage 4 CKD.

Background: A high score for controlling nutritional status (CONUT) due to poor nutritional status has been associated with adverse outcomes in patients with chronic heart failure. However, because little is known about the effect of CONUT score on mortality rates after transcatheter mitral valve repair, we evaluated nutrition screening tools for prognosis prediction in patients undergoing transcatheter mitral valve repair using the MitraClipTM system. MethodsâandâResults: We retrospectively analyzed 148 patients with severe mitral regurgitation (MR) who underwent MitraClipTM implantation between April 2018 and April 2021. The preprocedural CONUT scores were assessed at the time of hospitalization, the primary outcome was all-cause death, and the analysis was of the mortality and incidence rates of cardiac events 1 year post-operation. Functional MR was of ischemic origin in the majority of patients (69.6%), with a mean left ventricular ejection fraction of 48.9±15.8%. Kaplan-Meier curves indicated that all-cause death was significantly worse in the high-CONUT score group than in the low-CONUT score group. Cox hazard analysis showed a significant association between all-cause death and CONUT score, as well as MitraScore. Conclusions: Preprocedural CONUT score, as well as MitraScore, in patients undergoing transcatheter edge-to-edge mitral valve repair may predict an increased risk of all-cause death. This knowledge should allow the heart team to accurately assess the clinical implications and prognostic benefits of the procedure in individual patients.
RESUMO
BACKGROUND: Even with intracoronary imaging-guided stent optimisation, suboptimal haemodynamic outcomes post-percutaneous coronary intervention (PCI) can be related to residual lesions in non-stented segments. Preprocedural assessment of pathophysiological coronary artery disease (CAD) patterns could help predict the physiological response to PCI. AIMS: The aim of this study was to assess the relationship between preprocedural pathophysiological haemodynamic patterns and intracoronary imaging findings, as well as their association with physiological outcomes immediately post-PCI. METHODS: Data from 206 patients with chronic coronary syndrome enrolled in the ASET-JAPAN study were analysed. Pathophysiological CAD patterns were characterised using Murray law-based quantitative flow ratio (µQFR)-derived indices acquired from pre-PCI angiograms. The diffuseness of CAD was defined by the pullback pressure gradient (PPG) index. Intracoronary imaging in stented segments after stent optimisation was also analysed. RESULTS: In the multivariable analysis, diffuse disease - defined by the pre-PCI µQFR-PPG index - was an independent factor for predicting a post-PCI µQFR <0.91 (per 0.1 decrease of PPG index, odds ratio 1.57, 95% confidence interval: 1.07-2.34; p=0.022), whereas the stent expansion index (EI) was not associated with a suboptimal post-PCI µQFR. Among vessels with an EI ≥80% and post-PCI µQFR <0.91, 84.0% of those vessels had a diffuse pattern preprocedure. There was no significant difference in EI between vessels with diffuse disease and those with focal disease. The average plaque burden in the stented segment was significantly larger in vessels with a preprocedural diffuse CAD pattern. CONCLUSIONS: A physiological diffuse pattern preprocedure was an independent factor in predicting unfavourable immediate haemodynamic outcomes post-PCI, even after stent optimisation using intracoronary imaging. Preprocedural assessment of CAD patterns could identify patients who are likely to exhibit superior immediate haemodynamic outcomes following PCI.

Weather conditions influence the incidence of cardiovascular disease. However, few studies have investigated the association between weather temperature and humidity and cerebrovascular disease hospitalizations in a super-aging society. We included 606,807 consecutive patients with cerebrovascular disease admitted to Japanese acute-care hospitals between 2015 and 2019. The primary outcome was the number of cerebrovascular disease hospitalizations per day. Multilevel mixed-effects linear regression models were used to estimate the association of mean temperature and humidity, 1 day before hospital admission, with cerebrovascular disease hospitalizations, after adjusting for air pollution, hospital, and patient demographics. Lower mean temperatures and humidity < 70% or humidity ⧠70% are associated with an increased incidence of cerebrovascular disease hospitalization (coefficient, - 1.442 [- 1.473 to - 1.411] per °C, p < 0.001, coefficient, - 0.084 [- 0.112 to - 0.056] per%, p < 0.001, and coefficient, 0.136 [0.103 to 0.168] per %, p < 0.001, respectively). Lower mean temperatures and extremely lower or higher humidity are associated with an increased incidence of cerebrovascular disease hospitalization in a super-aging society.

BACKGROUND: Rotating-platform posterior-stabilized total knee arthroplasty (PS-TKA) has become a commonly used procedure. It has the potential risk of causing mobile-bearing spinout. In our study, we investigated the factors affecting the bearing thickness when performing rotating-platform PS-TKA. METHODS: This single-arm, prospective, single-hospital cohort study included 100 consecutive patients who underwent rotating-platform PS-TKA between September 2020 and August 2022. We examined the relationship between bearing thickness and several patient characteristics. RESULTS: The results of the univariate analysis showed that the bearing thickness was significantly associated with weight (risk ratio = 3.4; 95% confidence interval (CI) = 1.1-11.0; P = 0.016) and implant size of the tibia (risk ratio = 3.4; 95% CI = 1.0-11.5; P = 0.030). We performed multivariate analysis regarding the weight and implant size of the tibia. Neither the weight nor the implant size of the tibia was significantly different from the bearing thickness in the multivariate analysis. CONCLUSIONS: In rotating-platform PS-TKA, body weight and tibia size may affect the bearing thickness. Weight >60 kg and tibial implant size >67 cm may be risk factors for bearing thickening. Therefore, the surgery can be performed better if these risk factors are considered.

Background: Very severe aortic stenosis (AS) has a poor prognosis even in asymptomatic patients, and asymptomatic very severe AS is a Class IIa indication for aortic valve replacement, although the safety and effectiveness of transcatheter aortic valve implantation (TAVI) for very severe AS is not well-established. MethodsâandâResults: This study included 366 patients undergoing TAVI at a single center, with 85 and 281 patients in the very severe AS (peak velocity ≥5 m/s or mean pressure gradient (PG) ≥60 mmHg) and severe AS groups, respectively. Procedural and clinical outcomes at 1-year follow-up were compared between groups. The calcium scores were significantly higher in the very severe AS group (2,864.5 vs. 1,405.8 arbitrary units [AU] (P<0.001). Although the patient-prosthesis mismatch rate was higher in the very severe AS group (38.3% vs. 25.7%; P=0.029), there was no significant difference in the early safety and clinical efficacy between the groups (16.5% vs. 17.1% and 12.0% vs. 18.9%, respectively). Similarly, there was no significant difference in all-cause mortality at 1 year (4.8% vs. 9.8%). Conclusions: Despite a higher incidence of prosthesis-patient mismatch in those with very severe AS, the procedural and clinical outcomes were comparable to those in patients with severe AS. TAVI may be a reasonable treatment option for very severe AS.
