Abstract
BACKGROUND Although frailty is strongly associated with mortality in patients with heart failure (HF), the risk of which specific cause of death is associated with being complicated with frailty is unclear. We aimed to clarify the association between multidomain frailty and the causes of death in elderly patients hospitalized with HF. METHODS We analyzed data from the FRAGILE-HF cohort, where patients aged 65 years and older, hospitalized with HF, were prospectively registered between 2016 and 2018 in 15 Japanese hospitals before discharge and followed up for 2 years. All patients were assessed for physical, social, and cognitive dysfunction, and categorized into 3 groups based on their number of frailty domains (FDs, 0-1, 2, and 3). Kaplan-Meier survival analysis was used to evaluate the association between the number of FDs and all-cause mortality, whereas Fine-Gray competing risk regression analysis was used for assessing the impact on cause-specific mortality. RESULTS We analyzed 1181 patients with HF (81 years old in median, 57.4% were male), 530 (44.9%), 437 (37.0%), and 214 (18.1%) of whom were categorized into the FD 0 to 1, FD 2, and FD 3 groups, respectively. During the 2-year follow-up, 240 deaths were observed (99 HF deaths, 34 cardiovascular deaths, and 107 noncardiovascular deaths), and an increase in the number of FD was significantly associated with mortality (Log-rank: P<0.001). The Fine-Gray competing risk analysis adjusted for age and sex showed that FDs 2 (subdistribution hazard ratio, 1.77 [95% CI, 1.11-2.81]) and 3 (2.78, [95% CI, 1.69-4.59]) groups were associated with higher incidence of noncardiovascular death but not with HF and other cardiovascular deaths. CONCLUSIONS Although multidomain frailty is strongly associated with mortality in older patients with HF, it is mostly attributable to noncardiovascular death and not cardiovascular death, including HF death.

Prognostic impact of MitraScore in elderly Asian patients with heart failure: sub-analysis of FRAGILE-HF. ESC Heart Fail 2024; 11:1039-1050. [PMID: 38243376 DOI: 10.1002/ehf2.14658] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/04/2023] [Revised: 10/28/2023] [Accepted: 12/18/2023] [Indexed: 01/21/2024] Open
Abstract
AIMS MitraScore is a novel, simple, and manually calculatable risk score developed as a prognostic model for patients undergoing transcatheter edge-to-edge repair (TEER) for mitral regurgitation. As its components are considered prognostic in heart failure (HF), we aimed to investigate the usefulness of the MitraScore in HF patients. METHODS AND RESULTS We calculated MitraScore for 1100 elderly patients (>65 years old) hospitalized for HF in the prospective multicentre FRAGILE-HF study and compared its prognostic ability with other simple risk scores. The primary endpoint was all-cause deaths, and the secondary endpoints were the composite of all-cause deaths and HF rehospitalization and cardiovascular deaths. Overall, the mean age of 1100 patients was 80 ± 8 years, and 58% were men. The mean MitraScore was 3.2 ± 1.4, with a median of 3 (interquartile range: 2-4). A total of 326 (29.6%), 571 (51.9%), and 203 (18.5%) patients were classified into low-, moderate-, and high-risk groups based on the MitraScore, respectively. During a follow-up of 2 years, 226 all-cause deaths, 478 composite endpoints, and 183 cardiovascular deaths were observed. MitraScore successfully stratified patients for all endpoints in the Kaplan-Meier analysis (P < 0.001 for all). In multivariate analyses, MitraScore was significantly associated with all endpoints after covariate adjustments [adjusted hazard ratio (HR) (95% confidence interval): 1.22 (1.10-1.36), P < 0.001 for all-cause deaths; adjusted HR 1.17 (1.09-1.26), P < 0.001 for combined endpoints; and adjusted HR 1.24 (1.10-1.39), P < 0.001 for cardiovascular deaths]. The Hosmer-Lemeshow plot showed good calibration for all endpoints. The net reclassification improvement (NRI) analyses revealed that the MitraScore performed significantly better than other manually calculatable risk scores of HF: the GWTG-HF risk score, the BIOSTAT compact model, the AHEAD score, the AHEAD-U score, and the HANBAH score for all-cause and cardiovascular deaths, with respective continuous NRIs of 0.20, 0.22, 0.39, 0.39, and 0.29 for all-cause mortality (all P-values < 0.01) and 0.20, 0.22, 0.42, 0.40, and 0.29 for cardiovascular mortality (all P-values < 0.02). CONCLUSIONS MitraScore developed for patients undergoing TEER also showed strong discriminative power in HF patients. MitraScore was superior to other manually calculable simple risk scores and might be a good choice for risk assessment in clinical practice for patients receiving TEER and those with HF.

Effectiveness of neuromuscular electrical stimulation in patients with acute exacerbation of chronic obstructive pulmonary disease: A systematic review and meta-analysis. PHYSIOTHERAPY RESEARCH INTERNATIONAL 2024; 29:e2076. [PMID: 38411350 DOI: 10.1002/pri.2076] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/23/2023] [Revised: 01/26/2024] [Accepted: 02/12/2024] [Indexed: 02/28/2024]
Abstract
BACKGROUND AND PURPOSE This study aimed to investigate the effectiveness and acceptability of neuromuscular electrical stimulation (NMES) in patients with acute exacerbation of chronic obstructive pulmonary disease (COPD). METHODS We conducted a systematic review and meta-analysis to investigate the effectiveness and accessibility of NMES and compared them with usual care in patients with acute exacerbation of COPD by searching databases such as MEDLINE, EMBASE, and the Cochrane Central Register of Controlled Trials published up to April 2022. Randomized controlled trials (RCTs) involving patients with COPD who were treated within 3 weeks of acute exacerbation onset were included. The risk of bias was assessed using the RoB 2 tools. We pooled limb muscle strength and adverse events and performed a comparison between NMES and usual care. The quality of evidence was assessed using the Grading of Recommendations, Assessment, Development, and Evaluation approach. RESULTS Five RCTs, including 168 patients, met the eligibility criteria. The meta-analysis showed that limb muscle strength was significantly higher in the NMES group (four studies with 148 patients; standardized mean difference, 0.95; 95% confidence interval, 0.60-1.30; p < 0.001). The quality of evidence was very low due to the risk of bias within the studies, imprecision of the estimates, and small number of studies. Any adverse events served as outcomes in three studies (86 patients), although no adverse events occurred. CONCLUSION NMES is safe for patients with acute exacerbation of COPD and may maintain and improve limb muscle strength; however, the quality of evidence was very low.

Association and Prognostic Value of Multidomain Frailty Defined by Cumulative Deficit and Phenotype Models in Patients With Heart Failure. Can J Cardiol 2024; 40:677-684. [PMID: 38007218 DOI: 10.1016/j.cjca.2023.11.020] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2023] [Revised: 11/18/2023] [Accepted: 11/20/2023] [Indexed: 11/27/2023] Open
Abstract
BACKGROUND Frailty is associated with a poor prognosis in older patients with heart failure (HF). However, multidomain frailty assessment tools have not been established in patients with HF, and the association between the frailty phenotype and the deficit-accumulation frailty index in these patients is unclear. We aimed to understand this relationship and evaluate the prognostic value of the deficit-accumulation frailty index in older patients with HF. METHODS We retrospectively analyzed FRAGILE-HF cohort, which consisted of prospectively registered hospitalized patients with HF aged ≥ 65 years. The frailty index was calculated using 34 health-related items. The physical, social, and cognitive domains of frailty were evaluated using a phenotypic approach. The primary endpoint was all-cause mortality. RESULTS Among 1027 patients with HF (median age, 81 years; male, 58.1%; median frailty index, 0.44), a higher frailty index was associated with a higher prevalence in all domains of cognitive, physical, and social frailty defined by the phenotype model. During the 2-year follow-up period, a higher frailty index was independently associated with all-cause death even after adjustment for Meta-Analysis Global Group in Chronic Heart Failure (MAGGIC) score plus log B-type natriuretic peptide (per 0.1 increase: hazard ratio, 1.21; 95% confidence interval, 1.07-1.37; P = 0.002). The addition of the frailty index to the baseline model yielded statistically significant incremental prognostic value (net reclassification improvement, 0.165; 95% confidence interval, 0.012-0.318; P = 0.034). CONCLUSIONS A higher frailty index was associated with a higher prevalence of all domains of frailty defined by the phenotype model and provided incremental prognostic information with pre-existing risk factors in older patients with HF.

Identification of four genes responsible for antimicrobial resistance of MEL-B against S. aureus. Biochem Biophys Res Commun 2024; 699:149566.

Abstract
There is increasing interest in the antimicrobial activity of mannosylerythritol lipids-B (MEL-B) against Gram-positive bacteria such as Staphylococcus aureus (S. aureus). However, the specific molecules involved in MEL-B's antimicrobial action against S. aureus have not been identified. This study utilized the Nebraska transposon mutant library (NTML), which contains 1920 mutants, each lacking three-quarters of the genes found in S. aureus. The NTML was screened to identify mutants resistant to MEL-B. Four mutants (Accession Number: SAUSA300_0904, SAUSA300_0752, SAUSA300_0387, and SAUSA300_2311) largely unaffected by incubation with MEL-B, indicating MEL-B resistance. Despite the strong binding of MEL-B to these mutants, the four molecules encoded by the deleted genes (yjbI, clpP, pbuX, or brpS) in each mutant were not directly recognized by MEL-B. Given that these molecules are not localized on the outer surface of S. aureus and that the antibacterial activity of MEL-B against S. aureus is facilitated by the effective transfer of two antibacterial fatty acids (caprylic acid and myristoleic acid) to S. aureus via ME, the deletion of each of the four molecules may alter the peptidoglycan structure, potentially inhibiting the effective transfer of these antimicrobial fatty acids into S. aureus.

Latent ion tracks were finally observed in diamond. Nat Commun 2024; 15:1786. [PMID: 38413643 PMCID: PMC10899563 DOI: 10.1038/s41467-024-45934-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/13/2022] [Accepted: 02/08/2024] [Indexed: 02/29/2024] Open
Abstract
Injecting high-energy heavy ions in the electronic stopping regime into solids can create cylindrical damage zones called latent ion tracks. Although these tracks form in many materials, none have ever been observed in diamond, even when irradiated with high-energy GeV uranium ions. Here we report the first observation of ion track formation in diamond irradiated with 2-9 MeV C60 fullerene ions. Depending on the ion energy, the mean track length (diameter) changed from 17 (3.2) nm to 52 (7.1) nm. High resolution scanning transmission electron microscopy (HR-STEM) indicated the amorphization in the tracks, in which π-bonding signal from graphite was detected by the electron energy loss spectroscopy (EELS). Since the melting transition is not induced in diamond at atmospheric pressure, conventional inelastic thermal spike calculations cannot be applied. Two-temperature molecular dynamics simulations succeeded in the reproduction of both the track formation under MeV C60 irradiations and the no-track formation under GeV monoatomic ion irradiations.

The relationship between observation interval and prognosis in pancreatic cancer concomitant with intraductal papillary mucinous neoplasia. Pancreatology 2024; 24:73-77. [PMID: 37996267 DOI: 10.1016/j.pan.2023.11.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/26/2023] [Revised: 10/24/2023] [Accepted: 11/08/2023] [Indexed: 11/25/2023]
Abstract
BACKGROUND Intraductal papillary mucinous neoplasia (IPMN) is a risk factor for pancreatic cancer (PC). PC concomitant with IPMN shows rapid progression similar to de novo PC, therefore, the appropriate observation interval (OI) is not yet clear. PATIENTS AND METHOD This was a multicenter retrospective observational study, and patients with PC concomitant with IPMN were analyzed. OI was defined as the interval between the date of imaging at PC diagnosis and just before the diagnosis. Clinical factors of PC and prognosis were assessed according to OI. RESULTS From January 2010 to December 2018, 73 patients from 11 institutions were enrolled. The images performed just before PC diagnosis were contrast-enhanced CT/magnetic resonance imaging/endoscopic ultrasonography in 44/27/2 patients, respectively. The median cyst size was 14.0 mm, and the median main pancreatic duct diameter was 3.0 mm. The median OI was 6.8 months. In OI 6 months or less (OI ≤ 6 M)/OI more than 6 months (OI > 6 M), the mean tumor size, the frequencies of metastatic PC, resectable PC and early-stage PC were 20.1/21.5 mm (P = 0.91), 12.1 %/32.5 % (P = 0.05), 72.7 %/52.5 % (P = 0.09) and 27.3 %/25.0 % (P = 1.00), respectively. The median overall survival was 35.5 months in OI ≤ 6 M and 16.2 months in OI > 6 M (P = 0.05). CONCLUSION In OI 6 months or less, the rate of resectable PC was high, however, the rate of early PC was almost the same as that of OI more than 6 months. Approximately 10 % of cases found in the advanced stage with metastasis even if OI 6 months or less.

Abstract
BACKGROUND This study aimed to clarify the effects of exercise-based cardiac rehabilitation (CR) on patients with heart failure.Methods and Results: Patients were divided into groups according to intervention duration (<6 and ≥6 months). We searched for studies published up to July 2023 in Embase, MEDLINE, PubMed, and the Cochrane Library, without limitations on data, language, or publication status. We included randomized controlled trials comparing the efficacy of CR and usual care on mortality, prehospitalization, peak oxygen uptake (V̇O2), and quality of life. Seventy-two studies involving 8,495 patients were included in this review. It was found that CR reduced the risk of rehospitalization for any cause (risk ratio [RR] 0.80; 95% confidence interval [CI] 0.70-0.92) and for heart failure (RR 0.88; 95% CI 0.78-1.00). Furthermore, CR was found to improve exercise tolerance (measured by peak V̇O2and the 6-min walk test) and quality of life. A subanalysis performed based on intervention duration (<6 and ≥6 months) revealed a similar trend. CONCLUSIONS Our meta-analysis showed that although CR does not reduce mortality, it is effective in reducing rehospitalization rates and improving exercise tolerance and quality of life, regardless of the intervention duration.

Abstract
AIMS Although sarcopenia is common and associated with poor outcomes in patients with heart failure, its simple screening methods remain unclear. We aimed to investigate the predictive value of the Ishii score, which includes age, grip strength, and calf circumference, for sarcopenia and its prognostic predictability in patients with heart failure. METHODS This was a subanalysis of the FRAGILE-HF study. Receiver operating characteristic curves were used to evaluate the predictive value for sarcopenia. Patients were stratified into the high and low Ishii score groups based on the cutoff values of the Ishii score determined by the Youden index for sarcopenia, and the 1-year mortality rates were compared. RESULTS Of the 1262 study participants, 936 were evaluated with sarcopenia, and 184 (55 women, 129 men) were diagnosed with sarcopenia. The areas under the receiver operating characteristic curves for sarcopenia were 0.73 and 0.87 for women and men, respectively. The optimal cutoff values for predicting sarcopenia were 165 and 141 for women and men, respectively. Using these cutoff values, the sensitivity and specificity for sarcopenia were 70.9% and 68.5% for women and 88.4% and 69.7% for men, respectively. At 1 year, 151 (low Ishii score group, 98; high Ishii score group, 53) deaths were observed. Adjusted Cox proportional hazards analysis showed that the high Ishii score group was significantly associated with 1-year mortality. CONCLUSION Among older patients hospitalized for heart failure, the Ishii score is useful for predicting sarcopenia and 1-year mortality. Geriatr Gerontol Int 2024; 24: 147-153.

Effects of empagliflozin on progression of chronic kidney disease: a prespecified secondary analysis from the empa-kidney trial. Lancet Diabetes Endocrinol 2024; 12:39-50. [PMID: 38061371 PMCID: PMC7615591 DOI: 10.1016/s2213-8587(23)00321-2] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/05/2023] [Revised: 10/24/2023] [Accepted: 10/25/2023] [Indexed: 12/23/2023]
Abstract
BACKGROUND Sodium-glucose co-transporter-2 (SGLT2) inhibitors reduce progression of chronic kidney disease and the risk of cardiovascular morbidity and mortality in a wide range of patients. However, their effects on kidney disease progression in some patients with chronic kidney disease are unclear because few clinical kidney outcomes occurred among such patients in the completed trials. In particular, some guidelines stratify their level of recommendation about who should be treated with SGLT2 inhibitors based on diabetes status and albuminuria. We aimed to assess the effects of empagliflozin on progression of chronic kidney disease both overall and among specific types of participants in the EMPA-KIDNEY trial. METHODS EMPA-KIDNEY, a randomised, controlled, phase 3 trial, was conducted at 241 centres in eight countries (Canada, China, Germany, Italy, Japan, Malaysia, the UK, and the USA), and included individuals aged 18 years or older with an estimated glomerular filtration rate (eGFR) of 20 to less than 45 mL/min per 1·73 m2, or with an eGFR of 45 to less than 90 mL/min per 1·73 m2 with a urinary albumin-to-creatinine ratio (uACR) of 200 mg/g or higher. We explored the effects of 10 mg oral empagliflozin once daily versus placebo on the annualised rate of change in estimated glomerular filtration rate (eGFR slope), a tertiary outcome. We studied the acute slope (from randomisation to 2 months) and chronic slope (from 2 months onwards) separately, using shared parameter models to estimate the latter. Analyses were done in all randomly assigned participants by intention to treat. EMPA-KIDNEY is registered at ClinicalTrials.gov, NCT03594110. FINDINGS Between May 15, 2019, and April 16, 2021, 6609 participants were randomly assigned and then followed up for a median of 2·0 years (IQR 1·5-2·4). Prespecified subgroups of eGFR included 2282 (34·5%) participants with an eGFR of less than 30 mL/min per 1·73 m2, 2928 (44·3%) with an eGFR of 30 to less than 45 mL/min per 1·73 m2, and 1399 (21·2%) with an eGFR 45 mL/min per 1·73 m2 or higher. Prespecified subgroups of uACR included 1328 (20·1%) with a uACR of less than 30 mg/g, 1864 (28·2%) with a uACR of 30 to 300 mg/g, and 3417 (51·7%) with a uACR of more than 300 mg/g. Overall, allocation to empagliflozin caused an acute 2·12 mL/min per 1·73 m2 (95% CI 1·83-2·41) reduction in eGFR, equivalent to a 6% (5-6) dip in the first 2 months. After this, it halved the chronic slope from -2·75 to -1·37 mL/min per 1·73 m2 per year (relative difference 50%, 95% CI 42-58). The absolute and relative benefits of empagliflozin on the magnitude of the chronic slope varied significantly depending on diabetes status and baseline levels of eGFR and uACR. In particular, the absolute difference in chronic slopes was lower in patients with lower baseline uACR, but because this group progressed more slowly than those with higher uACR, this translated to a larger relative difference in chronic slopes in this group (86% [36-136] reduction in the chronic slope among those with baseline uACR <30 mg/g compared with a 29% [19-38] reduction for those with baseline uACR ≥2000 mg/g; ptrend<0·0001). INTERPRETATION Empagliflozin slowed the rate of progression of chronic kidney disease among all types of participant in the EMPA-KIDNEY trial, including those with little albuminuria. Albuminuria alone should not be used to determine whether to treat with an SGLT2 inhibitor. FUNDING Boehringer Ingelheim and Eli Lilly.

Impact of primary kidney disease on the effects of empagliflozin in patients with chronic kidney disease: secondary analyses of the EMPA-KIDNEY trial. Lancet Diabetes Endocrinol 2024; 12:51-60. [PMID: 38061372 DOI: 10.1016/s2213-8587(23)00322-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/05/2023] [Revised: 10/24/2023] [Accepted: 10/25/2023] [Indexed: 12/23/2023]
Abstract
BACKGROUND The EMPA-KIDNEY trial showed that empagliflozin reduced the risk of the primary composite outcome of kidney disease progression or cardiovascular death in patients with chronic kidney disease mainly through slowing progression. We aimed to assess how effects of empagliflozin might differ by primary kidney disease across its broad population. METHODS EMPA-KIDNEY, a randomised, controlled, phase 3 trial, was conducted at 241 centres in eight countries (Canada, China, Germany, Italy, Japan, Malaysia, the UK, and the USA). Patients were eligible if their estimated glomerular filtration rate (eGFR) was 20 to less than 45 mL/min per 1·73 m2, or 45 to less than 90 mL/min per 1·73 m2 with a urinary albumin-to-creatinine ratio (uACR) of 200 mg/g or higher at screening. They were randomly assigned (1:1) to 10 mg oral empagliflozin once daily or matching placebo. Effects on kidney disease progression (defined as a sustained ≥40% eGFR decline from randomisation, end-stage kidney disease, a sustained eGFR below 10 mL/min per 1·73 m2, or death from kidney failure) were assessed using prespecified Cox models, and eGFR slope analyses used shared parameter models. Subgroup comparisons were performed by including relevant interaction terms in models. EMPA-KIDNEY is registered with ClinicalTrials.gov, NCT03594110. FINDINGS Between May 15, 2019, and April 16, 2021, 6609 participants were randomly assigned and followed up for a median of 2·0 years (IQR 1·5-2·4). Prespecified subgroupings by primary kidney disease included 2057 (31·1%) participants with diabetic kidney disease, 1669 (25·3%) with glomerular disease, 1445 (21·9%) with hypertensive or renovascular disease, and 1438 (21·8%) with other or unknown causes. Kidney disease progression occurred in 384 (11·6%) of 3304 patients in the empagliflozin group and 504 (15·2%) of 3305 patients in the placebo group (hazard ratio 0·71 [95% CI 0·62-0·81]), with no evidence that the relative effect size varied significantly by primary kidney disease (pheterogeneity=0·62). The between-group difference in chronic eGFR slopes (ie, from 2 months to final follow-up) was 1·37 mL/min per 1·73 m2 per year (95% CI 1·16-1·59), representing a 50% (42-58) reduction in the rate of chronic eGFR decline. This relative effect of empagliflozin on chronic eGFR slope was similar in analyses by different primary kidney diseases, including in explorations by type of glomerular disease and diabetes (p values for heterogeneity all >0·1). INTERPRETATION In a broad range of patients with chronic kidney disease at risk of progression, including a wide range of non-diabetic causes of chronic kidney disease, empagliflozin reduced risk of kidney disease progression. Relative effect sizes were broadly similar irrespective of the cause of primary kidney disease, suggesting that SGLT2 inhibitors should be part of a standard of care to minimise risk of kidney failure in chronic kidney disease.

Abstract
Rationale and objectives We aimed to evaluate the impact of four-dimensional noise reduction filtering using a four-dimensional similarity filter (4D-SF) on radiation dose reduction in dynamic myocardial computed tomography perfusion (CTP). Materials and methods Forty-three patients who underwent dynamic myocardial CTP using 320-row computed tomography (CT) were included in the study. The original images were reconstructed using iterative reconstruction (IR). Three different CTP datasets with simulated noise, corresponding to 25%, 50%, and 75% reduction of the original dose (300 mA), were reconstructed using a combination of IR and 4D-SF. The signal-to-noise ratio (SNR) and contrast-to-noise ratio (CNR) were assessed, and CT-derived myocardial blood flow (CT-MBF) was quantified. The results were compared between the original and simulated images with radiation dose reduction. Results The median SNR (first quartile-third quartile) at the original, 25%-, 50%-, and 75%-dose reduced-simulated images with 4D-SF was 8.3 (6.5-10.2), 16.5 (11.9-21.7), 15.6 (11.0-20.1), and 12.8 (8.8-18.1) and that of CNR was 4.4 (3.2-5.8), 6.7 (4.6-10.3), 6.6 (4.3-10.1), and 5.5 (3.5-9.1), respectively. All the dose-reduced-simulated CTPs with 4D-SF had significantly higher image quality scores in SNR and CNR than the original ones (25%-, 50%-, and 75%-dose reduced vs. original images, p < 0.05, in each). The CT-MBF in 75%-dose reduced-simulated CTP was significantly lower than 25%-, 50%- dose-reduced-simulated, and original CTPs (vs. 75%-dose reduced-simulated images, p < 0.05, in each). Conclusion 4D-SF has the potential to reduce the radiation dose associated with dynamic myocardial CTP imaging by half, without impairing the robustness of MBF quantification.

Impact of the lateral skeletal stability following bilateral sagittal split ramus osteotomy for mandibular asymmetry. JPRAS Open 2023; 38:36-47. [PMID: 37675277 PMCID: PMC10477061 DOI: 10.1016/j.jpra.2023.08.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/16/2023] [Accepted: 08/06/2023] [Indexed: 09/08/2023] Open
Abstract
This study evaluated the stability of bilateral sagittal split ramus osteotomy (BSSRO) associated with positional plagiocephaly and temporal and masseter muscles using posteroanterior cephalogram analysis and three-dimensional computed tomography (3D-CT). This retrospective cohort study included 31 patients who underwent BSSRO for mandibular asymmetry. The cranial vault asymmetry index (CVAI) and the cephalic index were used as indicators of positional plagiocephaly. The distance from the vertical reference line to the menton (Me) was measured on posteroanterior cephalograms immediately and 1 year after surgery, and postoperative stability was assessed. Temporal and masseter muscles were constructed from 3D-CT data and their volumes were measured. Simple regression analysis showed a significant correlation between postoperative changes in the vertical reference line to the Me and the CVAI (R = 0.56, p = 0.001), the amount of surgical movement in the vertical reference line to the Me (R = 0.41, p = 0.023), and the variable temporal muscle volume (R = 0.27, p = 0.028). There was no significant correlation between postoperative changes in the vertical reference line to the Me and the cephalic index (R = 0.093, p = 0.62) and variable masseter muscle volume (R = 0.16, p = 0.38). According to multivariate analysis, CVAI (p = 0.003) and amount of surgical movement in the vertical reference line to the Me (p = 0.014) were significant predictors of postoperative change in the vertical reference line to the Me. Positional plagiocephaly and amount of surgical movement influence lateral skeletal stability following BSSRO for mandibular asymmetry.

Prognostic impact of cachexia by multi-assessment in older adults with heart failure: FRAGILE-HF cohort study. J Cachexia Sarcopenia Muscle 2023; 14:2143-2151. [PMID: 37434419 PMCID: PMC10570094 DOI: 10.1002/jcsm.13291] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/11/2022] [Revised: 03/17/2023] [Accepted: 06/12/2023] [Indexed: 07/13/2023] Open
Abstract
BACKGROUND Cachexia substantially impacts the prognosis of patients with heart failure (HF); however, there is no standard method for cachexia diagnosis. This study aimed to investigate the association of Evans's criteria, consisting of multiple assessments, with the prognosis of HF in older adults. METHODS This study is a secondary analysis of the data from the FRAGILE-HF study, a prospective multicentre cohort study that enrolled consecutive hospitalized patients aged ≥65 years with HF. Patients were divided into two groups: the cachexia and non-cachexia groups. Cachexia was defined according to Evans's criteria by assessing weight loss, muscle weakness, fatigue, anorexia, a decreased fat-free mass index and an abnormal biochemical profile. The primary outcome was all-cause mortality, as assessed in the survival analysis. RESULTS Cachexia was present in 35.5% of the 1306 enrolled patients (median age [inter-quartile range], 81 [74-86] years; 57.0% male); 59.6%, 73.2%, 15.6%, 71.0%, 44.9% and 64.6% had weight loss, decreased muscle strength, a low fat-free mass index, abnormal biochemistry, anorexia and fatigue, respectively. All-cause mortality occurred in 270 patients (21.0%) over 2 years. The cachexia group (hazard ratio [HR], 1.494; 95% confidence interval [CI], 1.173-1.903; P = 0.001) had a higher mortality risk than the non-cachexia group after adjusting for the severity of HF. Cardiovascular and non-cardiovascular deaths occurred in 148 (11.3%) and 122 patients (9.3%), respectively. The adjusted HRs for cachexia in cardiovascular mortality and non-cardiovascular mortality were 1.456 (95% CI, 1.048-2.023; P = 0.025) and 1.561 (95% CI, 1.086-2.243; P = 0.017), respectively. Among the cachexia diagnostic criteria, decreased muscle strength (HR, 1.514; 95% CI, 1.095-2.093; P = 0.012) and low fat-free mass index (HR, 1.424; 95% CI, 1.052-1.926; P = 0.022) were significantly associated with high all-cause mortality, but there was no significant association between weight loss alone (HR, 1.147; 95% CI, 0.895-1.471; P = 0.277) and all-cause mortality. CONCLUSIONS Cachexia evaluated by multi-assessment was present in one third of older adults with HF and was associated with a worse prognosis. A multimodal assessment of cachexia may be helpful for risk stratification in older patients with HF.

Combined Exercise and Education Program: Effect of Smaller Group Size and Longer Duration on Physical Function and Social Engagement among Community-Dwelling Older Adults. JAR LIFE 2023; 12:56-60. [PMID: 37519417 PMCID: PMC10374984 DOI: 10.14283/jarlife.2023.10] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/26/2023] [Accepted: 06/29/2023] [Indexed: 08/01/2023]
Abstract
Background Exercise, education, and social engagement are critical interventions for older adults for a healthy life expectancy and to improve their physical function. Objective To conduct a combined exercise and education (CEE) program for improved social engagement and physical function of older adults. Design Based on a short-term program we conducted in our previous study, in this study, the program was conducted for half the number of participants of the earlier study but for a longer duration. Setting A community of older adults in Ami, Japan, was the setting of the study. Participants 23 healthy older adults >65 years living in the community were the participants in the study. Interventions Five 80-minute sessions conducted once in two weeks comprised 60-min exercise instruction and 20-min educational lectures per session on health. We examined the improvement in physical and social engagement before and after participation. Physical function and health-related questionnaire data were collected before and after the program. Results Data analysis from 15 participants showed improved physical performance but no effect on social engagement. Conclusions A higher program frequency, rather than program duration, may be vital to improving exercise performance and social engagement and maximizing the effects of high group cohesion in small groups. Further studies are needed to develop more effective interventions to extend healthy life expectancy.

Prevalence and prognostic impact of the coexistence of cachexia and sarcopenia in older patients with heart failure. Int J Cardiol 2023; 381:45-51. [PMID: 36934990 DOI: 10.1016/j.ijcard.2023.03.035] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/03/2023] [Revised: 03/12/2023] [Accepted: 03/16/2023] [Indexed: 03/21/2023]
Abstract
BACKGROUND No study with an adequate patients' number has examined the relationship/overlap between sarcopenia and cachexia. We examined the prevalence of the overlap and prognostic implications of sarcopenia and cachexia in older patients with heart failure using well-accepted definitions. METHODS This was a post-hoc sub-analysis of the FRAGILE-HF study, a prospective, multicenter, observational study conducted at 15 hospitals in Japan. In total, 905 hospitalized older patients were classified into four groups based on the presence or absence of cachexia and/or sarcopenia, which were defined according to the Evans and Asian Working Group for Sarcopenia criteria revised in 2019, respectively. The primary endpoint was 2-year all-cause mortality. RESULTS Cachexia and sarcopenia prevalence rates were 32.7% and 22.7%, respectively. Patients were classified into the non-cachexia/non-sarcopenia (55.7%), cachexia/non-sarcopenia (21.7%), non-cachexia/sarcopenia (11.6%), and cachexia/sarcopenia (11.0%) groups. During the 2-year follow-up period after discharge, 158 (17.5%) all-cause deaths (124 cardiovascular deaths [CVD] and 34 non-CVD) were observed. The cachexia/sarcopenia group had the lowest body fat mass and exhibited significantly higher mortality rates (log-rank P < 0.001). Cox proportional hazard analysis revealed that cachexia/sarcopenia was an independent prognostic factor after adjusting for known prognostic factors (versus non-cachexia/non-sarcopenia: hazard ratio, 2.78; 95% confidence interval, 1.80-4.29; P < 0.001). Neither cachexia/non-sarcopenia nor non-cachexia/sarcopenia were significantly associated with all-cause mortality compared with non-cachexia/non-sarcopenia. CONCLUSIONS Cachexia and sarcopenia are prevalent among older hospitalized patients with heart failure; nonetheless, the overlap is not as prominent as previously expected. The presence of cachexia and sarcopenia is a risk factor for all-cause mortality.

High-intensity interval training versus moderate-intensity continuous training in patients with heart failure: a systematic review and meta-analysis. Heart Fail Rev 2023:10.1007/s10741-023-10316-3. [PMID: 37271780 DOI: 10.1007/s10741-023-10316-3] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Accepted: 04/12/2023] [Indexed: 06/06/2023]
Abstract
The effects of high-intensity interval training (HIIT) in patients with heart failure (HF) remain controversial. This systematic review and meta-analysis aimed to examine the efficacy of HIIT versus moderate-intensity continuous aerobic training (MCT) on exercise tolerance in patients with HF. We searched for studies published up to 4 March 2022 in Embase, MEDLINE, PubMed, and the Cochrane Library with no limitations on data, language, or publication status. We included randomized controlled trials comparing the efficacy of HIIT and MCT on peak oxygen uptake (VO2), as a measure of exercise tolerance. We pooled the data on peak VO2, compared HIIT to MCT, and conducted a sub-analysis if there was heterogeneity in the result. We identified 15 randomized controlled trials with 557 patients. Our meta-analysis showed that participants who underwent HIIT achieved a significantly higher peak VO2 than those who underwent MCT (mean difference 1.46 ml/kg/min, 95% confidence interval 0.39 to 2.53; participants = 557; studies = 15; I2 = 65.7%; very low-quality evidence). The meta-regression analysis, conducted as a sub-analysis to explore possible causes of heterogeneity, revealed that the difference in peak VO2 between HIIT and MCT was inversely associated with body mass index (r = - 0.508, p = 0.028, 95% confidence interval - 0.95 to - 0.07). Our systematic review showed that HIIT achieved a higher peak VO2 than MCT in patients with HF. In addition, HIIT may be more effective in improving exercise tolerance in patients with low body mass index.

Abstract
BACKGROUND Patients with advanced lung cancer tend to experience dyspnea. Pulmonary rehabilitation has been reported as a method for relieving dyspnea. However, exercise therapy imposes a high burden on patients, and it is difficult to sustain in many cases. Inspiratory muscle training (IMT) imposes a relatively low burden on patients with advanced lung cancer; however, its benefits have not been demonstrated. METHODS We retrospectively analyzed 71 patients who were hospitalized for medical treatment. The participants were divided into an exercise therapy group and an IMT load + exercise therapy group. Changes in maximal inspiratory pressure (MIP) and dyspnea were examined using a two-way repeated measures analysis of variance. RESULTS MIP variations significantly increase in the IMT load group, with significant differences between baseline and week 1, between week 1 and week 2, and between baseline and week 2. The analysis also showed that the variations in dyspnea decreased in the IMT load + exercise therapy group with significant differences between baseline and week 1 and between baseline and week 2. CONCLUSIONS The results show that IMT is useful and has a high persistence rate in patients with advanced lung cancer who present dyspnea and cannot perform high-intensity exercise therapy.

Abstract
BACKGROUND The incremental prognostic value of the six-minute walking test over conventional risk factors has not been evaluated in an adequate number of patients with heart failure with preserved ejection fraction (HFpEF). Therefore, we aimed to examine its prognostic significance using data from the FRAGILE-HF study. METHODS AND RESULTS A total of 513 older patients who were hospitalized for worsening heart failure were examined. Patients were classified according to the tertiles of six-minute walking distance (6MWD): T1 (<166 m), T2 (166-285 m), and T3 (≥285 m). During the 2-year follow-up period after discharge, 90 all-cause deaths occurred. Kaplan-Meier curves showed that the T1 group had significantly higher event rates than the other groups (log-rank p = 0.007). Cox proportional hazard analysis revealed that the T1 group was independently associated with lower survival, even after adjusting for conventional risk factors (T3: hazard ratio 1.79, 95% confidence interval 1.02-3.14, p = 0.042). The addition of the 6MWD to the conventional prognostic model showed a statistically significant incremental prognostic value (net reclassification improvement 0.27, 95% confidence interval 0.04-0.49; p = 0.019). CONCLUSIONS The 6MWD is associated with survival in patients with HFpEF and has an incremental prognostic value over conventional well-validated risk factors.

Comparison of risk factors for SARS-CoV-2 infection among healthcare workers during Omicron and Delta dominance periods in Japan. J Hosp Infect 2023; 134:97-107. [PMID: 36805085 PMCID: PMC9933573 DOI: 10.1016/j.jhin.2023.01.018] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/18/2022] [Revised: 01/18/2023] [Accepted: 01/23/2023] [Indexed: 02/18/2023]
Abstract
BACKGROUND The risk factors for coronavirus disease (COVID-19) among healthcare workers (HCWs) might have changed since the emergence of the highly immune evasive Omicron variant. AIM To compare the risk factors for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection among HCWs during the Delta- and Omicron-predominant periods. METHODS Using data from repeated serosurveys among the staff of a medical research centre in Tokyo, two cohorts were established: Delta period cohort (N = 858) and Omicron period cohort (N = 652). The potential risk factors were assessed using a questionnaire. Acute/current or past SARS-CoV-2 infection was identified by polymerase chain reaction or anti-nucleocapsid antibody tests, respectively. Poisson regression was used to calculate the risk ratio (RR) of infection risk. FINDINGS The risk of SARS-CoV-2 infection during the early Omicron-predominant period was 3.4-fold higher than during the Delta-predominant period. Neither working in a COVID-19-related department nor having a higher degree of occupational exposure to SARS-CoV-2 was associated with an increased infection risk during both periods. During the Omicron-predominant period, infection risk was higher among those who spent ≥30 min in closed spaces, crowded spaces, and close-contact settings without wearing mask (≥3 times versus never: RR: 6.62; 95% confidence interval: 3.01-14.58), whereas no such association was found during the Delta period. CONCLUSION Occupational exposure to COVID-19-related work was not associated with the risk of SARS-CoV-2 infection in the Delta or Omicron period, whereas high-risk behaviours were associated with an increased infection risk during the Omicron period.

Abstract
To date, an identification protocol for endocrine disruptors that bind to the thyroid hormone receptor (TR) has not been established. A method for screening and identifying TR-binding substances is highly required due to the existence of unknown TR-binding substances from the environment. Here, we conceived a chromatographic method using a molecularly imprinted polymer (MIP) to create a novel screening protocol for the endocrine disruptors. A receptor-imitating MIP was prepared using N-acetylthyroxine (AcetylT4) and 4-vinylpyridine as a pseudo-template and a functional monomer, respectively, based on the existing molecular recognition mechanism of the TR. The receptor-imitating MIP provided molecular recognition ability for all the TR-binding substances that were employed in this study. The prepared MIPs were packed into a high-performance liquid chromatography column for the simultaneous analysis of TR-binding and non-binding substances. The former was strongly retained, while the latter was not. The presence or absence of TR-binding/non-binding activity resulted in successful dichotomous separation. Additionally, the surface imprinting technique was applied to improve the separation performance of the MIP packing material. MIP-coated uniformly sized silica-based particles of 5 μm were successfully prepared, and the MIP-coated silica column enabled more efficient dichotomous separation of TR-binding and non-binding substances.

Abstract
Background: The purpose of this study was to investigate the effectiveness and clinical outcomes of inpatient rehabilitation for patients with severe COVID-19 in Japan. Methods: Patients with severe COVID-19 who underwent rehabilitation during hospitalization were included. The Medical Research Council (MRC) score and short physical performance battery (SPPB), such as physical function assessment and the intensive care unit (ICU) mobility scale, the functional status score for the ICU, and Barthel index as activities of daily living (ADLs) were evaluated at admission and discharge or transfer from the hospital. The correlation between SPPB at discharge and each factor at admission were also analyzed. Furthermore, the prevalence of sarcopenia was evaluated by defining SPPB of <9 points at discharge as sarcopenia. Results: The median age of the total of 23 patients was 59 years (interquartile range (IQR): 47−67), 73.9% were male, and the median PaO2/FiO2 at admission was 172.0 (IQR: 123.0−209.0). All physical function and ADL parameters were significantly improved from the time of admission to discharge (p = 0.014 for the MRC score and p < 0.001 for all others). Moreover, SPPB at discharge significantly correlated with WBC (Spearman’s rho = −0.473, p = 0.041), C-reactive protein (Spearman’s rho = −0.468, p = 0.044), and exhibited a significant trend with PaO2/FiO2 (Spearman’s rho = 0.429, p = 0.067) and age (Spearman’s rho = 0.409, p = 0.083). Although the median Barthel index at discharge was 90 points, 47% of patients had sarcopenia as defined by an SPPB of <9 points. Conclusions: Early rehabilitation for patients with severe COVID-19 improved physical function and ADLs during hospitalization. However, 47% of patients had the same level of sarcopenia at discharge.

Clinical Perspectives on Cardiac Rehabilitation After Heart Failure in Elderly Patients with Frailty: A Narrative Review. Ther Clin Risk Manag 2022; 18:1009-1028.

Abstract
The purpose of this narrative review is to examine rehabilitation modalities for patients with heart failure and Frailty who require comprehensive intervention. Ischemic heart disease is the leading cause of death worldwide, accounting for 16% of global mortality. Due to population growing and aging, the total number of heart failure patients continues to rise, a condition known as the heart failure pandemic. Furthermore, frailty has been associated with an increased risk for heart failure and increased morbidity and mortality. The 2021 update of the 2017 ACC expert consensus decision pathway for optimization of HF treatment has become more concerning, citing frailty as one of the 10 most important issues associated with heart failure with reduced ejection fraction (HFrEF). Frailty and heart failure share common pathological mechanisms and are associated with poor clinical outcomes. Most studies of frailty in patients with heart failure primarily focus on physical frailty, and associations between psycho-psychological and social factors such as cognitive dysfunction and social isolation have also been reported. These results suggest that a more comprehensive assessment of frailty is important to determine the risk in patients with heart failure. Therefore, mechanisms of the three domains, including not only physical frailty but also cognitive, psychological, spiritual, and social aspects, should be understood. In addition to interventions in these three domains, nutritional and pharmacological interventions are also important and require tailor-made interventions for the widely varied conditions associated with heart failure and frailty. Although several studies have shown a relationship between frailty and prognosis in patients with heart failure, interventions to improve the prognosis have not yet been established. Further information is needed on frailty intervention by a multidisciplinary team to improve the prognosis.

Abstract
Objective This study aimed to compare the effects of moderate- and high-intensity resistance and impact training (MiRIT and HiRIT, respectively) on changes in bone mineral density (BMD) in postmenopausal women with osteoporosis. Methods Randomized controlled trials that compared the intervention effects of MiRIT and HiRIT were used as selection criteria to assess study patients with osteoporosis or an osteoporotic condition. Database searches were conducted on August 25, 2022, using CENTRAL, PubMed, CINAHL Web of Science, EMBASE, and MEDLINE. A risk of bias assessment was performed using Revised Cochrane risk of bias tool for the assessment of randomized controlled trials. Point estimates and 95 % confidence intervals of change in BMD derived using dual-energy X-ray absorptiometry were collected as outcomes, and a meta-analysis was performed using the amount of change in BMD before and after the intervention. Adverse event data were also collected. Results The search yielded six studies (391 patients, mean age 53–65 years) that met the inclusion criteria. The intervention duration ranged from 24 weeks to 13 months. Compared with the MiRIT group, the HiRIT group showed significantly improved BMD of the lumbar spine (standardized mean difference 2.37 [0.10–4.65]). However, a high degree of heterogeneity was observed for three studies (154 patients, I2 = 98 %). Almost all studies reported minimal adverse events. The certainty of evidence was extremely low because of the risk of bias, inconsistency among studies, and imprecision in terms of sample size. Conclusion Postmenopausal women with osteoporosis may achieve more significantly improved lumbar spine BMD with HiRIT than with MiRIT. The effects of moderate versus high-intensity training on bone mineral density in postmenopausal woman were compared. High-intensity training would be more beneficial for improving bone mineral density of the lumbar spine than moderate one. Almost all studies reported minimal adverse events. However, the lack of certainty associated with the evidence should be considered for clinical application.

Abstract
Abstract
Background/Purpose
Worsening renal function (WRF) can sometimes occur in the patients with acute decompensated heart failure (ADHF) and increase the risk of morbidity and mortality (1). In a previous study, it was reported that fractional excretion of sodium (FENa) reflects net sodium reabsorption from nephron segments and predicts WRF during treating ADHF (2). On the other hand, recently the new drugs which approach urine concentration mechanism and affect urine osmolality (U-OSM), such as tolvaptan and sodium-glucose cotransporter-2 inhibitor, have begun to be widely used as treatment of heart failure. Thus, we focused on U-OSM, which reflects not only sodium handling but also water excretion controlled by the collecting duct, and evaluated the association between WRF and U-OSM. Moreover, previous studies have demonstrated that FENa, fractional excretion of urea nitrogen and transtubular potassium concentration gradient are markers for long-term prognosis in patients with ADHF (3–5). Therefore, we also studied whether U-OSM can predict prognosis in ADHF.
Methods
A total of 157 patients admitted to our hospital because of a primary diagnosis of ADHF from February 2020 through July 2021 were retrospectively reviewed. U-OSM in the spot urinary samples were examined within 72 hours after admission. U-OSM was calculated based on the following validated formula (6): U-OSM = 1.07 × {2 × [urine sodium (mEq/L)] + [urine urea nitrogen (mg/dL)]/2.8 + [urine creatinine (mg/dl)] × 2/3} + 16.2. The primary outcome was the occurrence of WRF during hospitalization. WRF was defined as increased serum creatinine ≥0.3 mg/dL from baseline (7). The secondary outcome was the occurrence of ADHF readmission and all-cause death within 180 days after discharge.
Results
Primary Outcome. WRF developed in 46% of all patients. In the patients that developed WRF during hospitalization, U-OSM was significantly lower than in the patients without WRF (366±106 mOsm/L versus 430±128 mOsm/L; P<0.001). Receiver operating characteristic curve analysis revealed the optimal cutoff values of U-OSM was 403 mOsm/L (AUC 0.64; 95% CI: 0.56–0.72; P<0.001) to predict the WRF (Figure 1). On multivariable logistic regression analysis, U-OSM (OR, 1.99, 95% CI: 1.27–3.12; p=0.003) and serum creatinine (OR, 1.00, 95% CI: 0.99–1.00; P=0.009) were independent predictors of WRF.
Secondary Outcome. There were 34 patients (22%) readmitted and 9 patients (6%) died within 180 days after discharge. ROC curve analysis revealed the optimal cutoff values of U-OSM as 349 mOsm/L (C-statistic 0.74; 95% CI: 0.65–0.83; P<0.001) to predict ADHF readmission and all-cause death within 180 days (Figure 2A). On Kaplan-Meier analysis, the secondary outcome was significantly higher in patients with U-OSM<349 mOsm/L (u-OSM≥349, 57%, U-OSM<349, 43%; HR, 0.99; 95% CI: 0.99–1.00, P<0.001) (Figure 2B).
Conclusion
U-OSM on admission may be a predictor of WRF and a prognostic marker in ADHF patients.

Abstract
Advancement in systemic therapy has increased the importance of local control (LC) of bone metastatic sites treated with radiotherapy in intermediate-term survivors (surviving ≥1 year). To establish individualized radiotherapy for bone metastases, factors affecting LC of bone metastases treated with traditional fractionated moderate dose palliative radiotherapy (FMRT) in intermediate-term survivors were evaluated. Between January 2010 and December 2019, 317 lesions in 240 patients treated with FMRT for bone metastases surviving for at least 1 year and followed-up with CT for at least 6 months were reviewed retrospectively. The median survival and radiographic follow-up times were 24 months (range, 12-123 months) and 20 months (range, 1-119 months), respectively. The median FMRT dose [biologically effective dose (BED)10] was 39.0 Gy (range, 28.0-71.7 Gy). Multivariate analysis revealed that age (≥70 years), non-vertebral bone metastasis, bone metastasis from moderate and unfavorable primary tumor sites (esophageal, colorectal, hepatobiliary/pancreatic, kidney/ureter and sarcoma/melanoma cancers), and no administration of post-FMRT bone-modifying agents (BMAs) were unfavorable factors for LC of bone metastasis. The 2-year LC rates for FMRT doses (BED10) ≤39.0 Gy and >39.0 Gy were 90 and 87%, respectively. The 2-year LC rates of patients administered and not administered post-FMRT antineoplastic agents (ATs) were 91 and 78%, respectively. The sites of bone metastasis and primary tumors, and post-FMRT BMAs were factors associated with LC of bone metastasis in long-term survivors. However, a FMRT dose (BED10) ≥39.0 Gy and post-FMRT ATs were not significant factors.

Abstract
The basidiomycetous yeast Pseudozyma tsukubaensis produces a mannosylerythritol lipid (MEL) homologue, a diastereomer type of MEL-B, from olive oil. In a previous study, MEL-B production was increased by the overexpression of lipase PaLIPAp in P. tsukubaensis 1E5, through the enhancement of oil consumption. In the present study, RNA sequence analysis was used to identify a promoter able to induce high-level PaLIPA expression. The recombinant strain, expressing PaLIPA via the translation elongation factor 1 alpha/Tu promoter, showed higher lipase activity, rates of oil degradation, and MEL-B production than the strain which generated in our previous study.

Abstract
Background The purpose of this study was to clarify the prevalence, association with frailty and exercise capacity, and prognostic implication of sarcopenic obesity in patients with heart failure. Methods The present study included 779 older adults hospitalized with heart failure (median age: 81 years; 57.4% men). Sarcopenia was diagnosed based on the guidelines by the Asian Working Group for Sarcopenia. Obesity was defined as the percentage of body fat mass (FM) obtained by bioelectrical impedance analysis. The FM cut-off points for obesity were 38% for women and 27% for men. The primary endpoint was 1-year all-cause death. We assessed the associations of sarcopenic obesity occurrence with the short physical performance battery (SPPB) score and 6-minute walk distance (6MWD). Results The rates of sarcopenia and obesity were 19.3 and 26.2%, respectively. The patients were classified into the following groups: non-sarcopenia/non-obesity (58.5%), non-sarcopenia/obesity (22.2%), sarcopenia/non-obesity (15.3%), and sarcopenia/obesity (4.0%). The sarcopenia/obesity group had a lower SPPB score and shorter 6MWD, which was independent of age and sex (coefficient, − 0.120; t-value, − 3.74; P < 0.001 and coefficient, − 77.42; t-value, − 3.61; P < 0.001; respectively). Ninety-six patients died during the 1-year follow-up period. In a Cox proportional hazard analysis, sarcopenia and obesity together were an independent prognostic factor even after adjusting for a coexisting prognostic factor (non-sarcopenia/non-obesity vs. sarcopenia/obesity: hazard ratio, 2.48; 95% confidence interval, 1.22–5.04; P = 0.012). Conclusion Sarcopenic obesity is a risk factor for all-cause death and low physical function in older adults with heart failure.

Abstract
Background Early rehabilitation allows patients to better perform the activities of daily living after hospital discharge. A specialized physical therapist has been assigned as part of the early rehabilitation, but the effectiveness of the program remains unclear. We investigated how early rehabilitation provided by a specialized physical therapist affects ADL in patients with sepsis. Methods This was a retrospective cohort study. This study’s subjects were sepsis patients who entered the advanced emergency critical care center of Shinshu University Hospital between April 2014 and March 2020. Electronic medical records were reviewed to obtain information on demographic characteristics, severity score, primary source of infection, therapeutic medication, the number of days after hospital admittance until rehabilitation begins, length of hospital stay, discharge to home, and an assessment of daily living activities for each patient. The patients were divided into two groups based on whether they were treated before or after a specialized physical therapist had been hired by the advanced emergency critical care center. Results Assigning a physical therapist to a patient significantly shortened the number of days until rehabilitation began. In a multivariable model, the strongest predictors of return to independent living after hospital discharge were (1) assigning a specialized physical therapist (odds ratio = 2.40; 95% confidence interval = 1.09–5.79; P = 0.050) and (2) the number of days until rehabilitation started (odds ratio = 0.24; 95% confidence interval = 0.08–0.76; P = 0.014). Conclusions Assigning a specialized physical therapist to sepsis patients at an advanced emergency critical care center significantly shortened the number of days until a patient can begin rehabilitation after hospital admittance and improved activities of daily living after hospital discharge.

Abstract
BACKGROUND The aim of this study was to clarify the effectiveness of pulmonary rehabilitation in patients after exacerbations of COPD and to explore the initiation timing of pulmonary rehabilitation. METHODS Systematic review and meta-analysis were performed to assess the effects of pulmonary rehabilitation in subjects with exacerbations of COPD on mortality and readmission compared with usual care. We searched for studies published up to October 2020 in MEDLINE, Embase, Cochrane Library, and other sources. Risk of bias was assessed for the randomization process, deviations from intended interventions, missing outcome data, outcome measurements, and selection of the reported result using the Risk of Bias 2 tool. We pooled mortality and readmission data and performed comparisons between pulmonary rehabilitation and usual care. The subgroup analysis compared pulmonary rehabilitation at different start times (early: ≤ 1 week from admission; and late: > 1 week from admission). RESULTS We identified 10 randomized trials (1,056 participants). Our meta-analysis showed a clinically relevant reduction in readmission up to 3-6 months after pulmonary rehabilitation in both early group (4 trials, 190 subjects; risk ratio [RR] 0.58, [95% CI 0.34-0.99]) and late group (3 trials, 281 subjects; RR 0.48, [95% CI 0.32-0.71]). However, pulmonary rehabilitation had no significant effect on mortality 1 y later compared with usual care (4 trials, 765 subjects; RR 1.27, [95% CI 0.91-1.79]). CONCLUSIONS Pulmonary rehabilitation showed short-term effects for subjects with exacerbations of COPD even if initiated within 1 week; however, further study is required to determine its long-term effects.

Abstract
Aims Although evidence suggests that cognitive decline and physical frailty in elderly patients with heart failure (HF) are associated with prognosis, the impact of concurrent physical frailty and cognitive impairment, that is, cognitive frailty, on prognosis has yet to be fully investigated. The current study sought to investigate the prevalence and prognostic impact of cognitive frailty in elderly patients with HF. Methods and results This study is a sub‐analysis of FRAGILE‐HF, a prospective multicentre observational study involving patients aged ≥65 years hospitalized for HF. The Fried criteria and Mini‐Cog were used to diagnose physical frailty and cognitive impairment, respectively. The association between cognitive frailty and the combined endpoint of mortality and HF rehospitalization within 1 year was then evaluated. Among the 1332 patients identified, 1215 who could be assessed using Mini‐Cog and the Fried criteria were included in this study. Among those included, 279 patients (23.0%) had cognitive frailty. During the follow‐up 1 year after discharge, 398 combined events were observed. Moreover, cognitive frailty was determined to be associated with a higher incidence of combined events (log‐rank: P = 0.0146). This association was retained even after adjusting for other prognostic factors (hazard ratio: 1.55, 95% confidence interval: 1.13–2.13). Furthermore, a sensitivity analysis using grip strength, short physical performance battery, and gait speed to determine physical frailty instead of the Fried criteria showed similar results. Conclusions This cohort study found that 23% of elderly patients with HF had cognitive frailty, which was associated with a 1.55‐fold greater risk for combined events within 1 year compared with patients without cognitive frailty.

Roles of mannosylerythritol lipid-B components in antimicrobial activity against bovine mastitis-causing Staphylococcus aureus. World J Microbiol Biotechnol 2022; 38:54.

Abstract
Mannosylerythritol lipid-B (MEL-B), which comprises ester-bonded hydrophilic ME and hydrophobic fatty acids, is a bio-surfactant with various unique properties, including antimicrobial activity against most gram-positive bacteria. The gram-positive Staphylococcus aureus is a causative pathogen of dairy cattle mastitis, which results in considerable economic loss in the dairy industry. Here, we demonstrate the efficacy of MEL-B as a disinfectant against bovine-derived S. aureus and elucidate a mechanism of action of MEL-B in the inhibition of bacterial growth. The growth of bovine mastitis causative S. aureus BM1006 was inhibited when cultured with MEL-B above 10 ppm. The activity of MEL-B required fatty acids (i.e., caprylic and myristoleic acids) as ME, the component of MEL-B lacking fatty acids, did not inhibit the growth of S. aureus even at high concentrations. Importantly, ME-bound fatty acids effectively inhibited the growth of S. aureus when compared with free fatty acids. Specifically, the concentrations of ME-bound fatty acids and free caprylic and myristoleic acids required to inhibit the growth of S. aureus were 10, 1442, and 226 ppm, respectively. The involvement of ME in the antimicrobial activity of MEL-B was confirmed by digestion of MEL-B with alkali, which dissociated ME and fatty acids. These results indicated that a mechanism of action of MEL-B in inhibiting the growth of S. aureus could be explained by the effective transporting of antimicrobial fatty acids to the bacterial surface via hydrophilic ME.

Abstract
BACKGROUND AND AIMS Frailty and sarcopenia are common and confer poor prognosis in elderly patients with heart failure; however, gender differences in its prevalence or prognostic impact remain unclear. METHODS AND RESULTS We included 1332 patients aged ≥65 years, who were hospitalized for heart failure. Frailty and sarcopenia were defined using the Fried phenotype model and Asian Working Group for Sarcopenia criteria, respectively. Gender differences in frailty and sarcopenia, and interactions between sex and prognostic impact of frailty/sarcopenia on 1-year mortality were evaluated. Overall, 53.9% men and 61.0% women and 23.7% men and 14.0% women had frailty and sarcopenia, respectively. Although sarcopenia was more prevalent in men, no gender differences existed in frailty after adjusting for age. On Kaplan-Meier analysis, frailty and sarcopenia were significantly associated with 1-year mortality in both sexes. On Cox proportional hazard analysis, frailty was associated with 1-year mortality only in men, after adjusting for confounding factors (hazard ratio [HR], 1.94; 95% confidence interval [CI], 1.19-3.16; P = 0.008 for men; HR, 1.63; 95% CI, 0.84-3.13; P = 0.147 for women); sarcopenia was an independent prognostic factor in both sexes (HR, 1.93; 95% CI, 1.13-3.31; P = 0.017 for men; HR, 3.18; 95% CI, 1.59-5.64; P = 0.001 for women). There were no interactions between sex and prognostic impact of frailty/sarcopenia (P = 0.806 for frailty; P = 0.254 for sarcopenia). CONCLUSIONS Frailty and sarcopenia negatively affect older patients with heart failure from both sexes. CLINICAL TRIALS This study was registered at the University Hospital Information Network (UMIN-CTR, unique identifier: UMIN000023929) before the first patient was enrolled.

Abstract
Aims A patient's understanding of his or her own comorbidities is part of the recommended patient education for those with heart failure. The accuracy of patients' understanding of their comorbidities and its prognostic impact have not been reported. Methods and results Patients hospitalized for heart failure (n = 1234) aged ≥65 years (mean age: 80.1 ± 7.7 years; 531 females) completed a questionnaire regarding their diagnoses of diabetes, malignancy, stroke, hypertension, chronic obstructive pulmonary disease (COPD), and coronary artery disease (CAD). The patients were categorized into three groups based on the number of agreements between self‐reported comorbidities and provider‐reported comorbidities: low (1–2, n = 19); fair (3–4, n = 376); and high (5–6, n = 839) agreement groups. The primary outcome was a composite of all‐cause mortality or heart failure rehospitalization at 1 year. The low agreement group had more comorbidities and a higher prevalence of a history of heart failure. The agreement was good for diabetes (κ = 0.73), moderate for malignancy (κ = 0.56) and stroke (κ = 0.50), and poor‐to‐fair for hypertension (κ = 0.33), COPD (κ = 0.25), and CAD (κ = 0.30). The fair and low agreement groups had poorer outcomes than the good agreement group [fair agreement group: hazard ratio (HR): 1.25; 95% confidence interval (CI): 1.01–1.56; P = 0.041; low agreement group: HR: 2.74: 95% CI: 1.40–5.35; P = 0.003]. Conclusions The ability to recognize their own comorbidities among older patients with heart failure was low. Patients with less accurate recognition of their comorbidities may be at higher risk for a composite of all‐cause mortality or heart failure rehospitalization.

Work status before admission relates to prognosis in older patients with heart failure partly through social frailty. J Cardiol 2021; 79:439-445.

Abstract
BACKGROUND No reports explicitly examined the relationship between work defined as a certain type of social participation or role and the protective effect on the prognosis of patients with heart failure (HF) by preventing frailty. Therefore, this study examined whether social participation through work before admission relates to future adverse events in HF patients aged ≥65 years, and whether each frailty domain mediates the association between work and prognosis as a second analysis of a multi-centered prospective study (FRAGILE-HF study). METHODS We retrospectively reviewed 1,332 older patients with HF whose work status before admission to the hospital were investigated. We assessed the physical, cognitive, and social domains of frailty and performed causal mediation analysis to examine the mediating relationship of each frail domain between work status before admission and 1-year combined events (HF-related readmission and all-cause death). RESULTS The subjects' median age was 81 years, and 56.9% (758/1,332) were male. Among the three domains of frailty, work before admission reduced only social frailty after adjusting for confounding factors (odds ratio: 0.505, 95% confidence interval: 0.364-0.701). Patients with work before admission had a significantly better prognosis (hazard ratio: 0.720, 95% confidence interval: 0.523-0.989). Only social frailty partly mediated the relationship between work status and combined events (p <0.05). CONCLUSIONS Work status before admission is associated with 1-year combined events, in part through social frailty.

Abstract
BACKGROUND Over the past decades, remarkable advancements in systemic drug therapy have improved the prognosis of patients with bone metastases. Individualization is required in external beam radiotherapy (EBRT) for bone metastases according to the patient's prognosis. To establish individualized EBRT for bone metastases, we investigated factors that affect the local control (LC) of bone metastases. METHODS Between January 2010 and December 2019, 536 patients received EBRT for 751 predominantly osteolytic bone metastases. LC at EBRT sites was evaluated with a follow-up computed tomography. The median EBRT dose was biologically effective dose (BED10) (39.0) (range of BED10: 14.4-71.7 Gy). RESULTS The median follow-up time and median time of computed tomography follow-up were 11 (range 1-123) months and 6 (range 1-119) months, respectively. The 0.5- and 1-year overall survival rates were 73% and 54%, respectively. The 0.5- and 1-year LC rates were 83% and 79%, respectively. In multivariate analysis, higher age (≥ 70 years), non-vertebral bone metastases, unfavorable primary tumor sites (esophageal cancer, colorectal cancer, hepatobiliary/pancreatic cancer, renal/ureter cancer, sarcoma, melanoma, and mesothelioma), lower EBRT dose (BED10 < 39.0 Gy), and non-administration of bone-modifying agents (BMAs)/antineoplastic agents after EBRT were significantly unfavorable factors for LC of bone metastases. There was no statistically significant difference in the LC between BED10 = 39.0 and BED10 > 39.0 Gy. CONCLUSIONS Regarding tumor-related factors, primary tumor sites and the sites of bone metastases were significant for the LC. As for treatment-related factors, lower EBRT doses (BED10 < 39.0 Gy) and non-administration of BMAs/antineoplastic agents after EBRT were associated with poor LC. Dose escalation from BED10 = 39.0 Gy did not necessarily improve LC.

Clinical impact of antibodies to Sp100 on a bacterial infection in patients with primary biliary cholangitis. J Clin Lab Anal 2021; 35:e24040. [PMID: 34623692 PMCID: PMC8605154 DOI: 10.1002/jcla.24040] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/11/2021] [Revised: 08/26/2021] [Accepted: 09/23/2021] [Indexed: 11/22/2022] Open
Abstract
BACKGROUND A specific antinuclear antibody for primary biliary cholangitis (PBC) is anti-Sp100, which was recognized as a serological marker of concurrent urinary tract infection. We sought to determine the clinical characteristics of PBC patients who had anti-Sp100. PATIENTS AND METHODS Fifty-one patients with PBC and 10 healthy controls (HCs) were enrolled. Anti-Sp100 were determined with an ELISA method. Lipopolysaccharide-binding protein (LBP) was measured as a serological hallmark for bacterial infection. The correlations of anti-Sp100 with demographic, laboratory, and pathological parameters were investigated. RESULTS Six of the 51 (11.8%) PBC patients had anti-Sp100, whereas none of the HCs did. There was no significant difference in the frequency of antimitochondrial antibodies (AMAs) between PBC patients with and without anti-Sp100 (67% vs. 82%, p = 0.5839). Biochemical and immunological parameters were not associated with the emergence of anti-Sp100 in these patients. The clinical stage by Scheuer classification was not correlated with the existence of anti-Sp100. No significant difference in the serum LBP levels was found between PBC patients with and without anti-Sp-100, although serum LBP levels were significantly higher in PBC patients with anti-Sp100 than in HCs (8.30 ± 2.24 ng/ml, vs. 5.12 ± 2.48 ng/ml, p = 0.0022). The frequency of granuloma formation was higher in the liver specimens of PBC patients with anti-Sp100 than in those without anti-Sp100 (67% vs 29%, p = 0.0710). CONCLUSION anti-Sp100 does not become a complementary serological marker for PBC in AMA-negative patients. A bacterial infection may trigger the production of anti-Sp100. Another factor is required to initiate the autoantibody production.

Abstract
Background Frailty is conceptualized as an accumulation of deficits in multiple areas and is strongly associated with the prognosis of heart failure (HF). However, the social domain of frailty is less well investigated. We prospectively evaluated the clinical characteristics and prognostic impact of social frailty (SF) in elderly patients with HF. Methods and Results FRAGILE‐HF (prevalence and prognostic value of physical and social frailty in geriatric patients hospitalized for heart failure) is a multicenter, prospective cohort study focusing on patients hospitalized for HF and aged ≥65 years. We defined SF by Makizako’s 5 items, which have been validated as associated with future disability. The primary end point was a composite of all‐cause death and rehospitalization because of HF. The impact of SF on all‐cause mortality alone was also evaluated. Among 1240 enrolled patients, 825 (66.5%) had SF. During the 1‐year observation period after discharge, the rates of the combined end point and all‐cause mortality were significantly higher in patients with SF than in those without SF (Log‐rank test: both P < 0.05). SF remained as significantly associated with both the combined end point (hazard ratio, 1.30; 95% CI, 1.02–1.66; P = 0.038) and all‐cause mortality (hazard ratio, 1.53; 95% CI, 1.01–2.30; P = 0.044), even after adjusting for key clinical risk factors. Furthermore, SF showed significant incremental prognostic value over known risk factors for both the combined end point (net‐reclassification improvement: 0.189, 95% CI, 0.063–0.316, P = 0.003) and all‐cause mortality (net‐reclassification improvement: 0.234, 95% CI, 0.073–0.395, P = 0.004). Conclusions Among hospitalized geriatric patients with HF, two thirds have SF. Evaluating SF provides additive prognostic information in elderly patients with HF.

Abstract
OBJECTIVE: To retrospectively evaluate the clinical outcomes of pre-operative endovascular coil embolisation (ECE) for chronic pulmonary aspergillosis (CPA).METHODS: We evaluated surgical patients with CPA between November 2016 and April 2020. Pre-operative ECE for CPA with severe adhesions was selectively performed to reduce intra-operative blood loss. ECE procedures, operative procedures, intra-operative blood loss and complications were evaluated.RESULTS: Twenty-eight patients (21 males and 7 females; median age: 55 years) were included in the study. Of the 28 patients, 8 (28.6%) underwent pre-operative ECE. Technical success rate in pre-operative ECE was 100%. The median time required for ECE procedures was 123 min. The median number of vessels embolised per procedure was 2.5. The median period between embolisation and surgery was 5 days. Major complications were observed in three patients (10.7%). There were no significant differences between patients with and without pre-operative ECE in operative time (284 vs. 365 min, respectively, P = 0.7602) and intra-operative blood loss (294 vs. 228 mL, respectively, P = 0.8987).CONCLUSIONS: Pre-operative ECE for CPA appears to be feasible and safe; however, its role in reducing intra-operative blood loss needs further investigation.
