Collagen patches releasing phosphatidylserine liposomes guide M1-to-M2 macrophage polarization and accelerate simultaneous bone and muscle healing.

Bilateral communication between bones and muscles is essential for healing composite bone-muscle injuries from orthopedic surgeries and trauma. However, these injuries are often characterized by exaggerated inflammation, which can disrupt bone-muscle crosstalk, thereby seriously delaying the healing of either tissue. Existing approaches are largely effective at healing single tissues.

Long-term clinical outcomes following percutaneous coronary intervention in patients aged 90 years and older.

Background: In an aging society, percutaneous coronary intervention (PCI) for super-elderly patients is commonly performed in clinical practice. However, data are scarce regarding the clinical features and outcomes of this population.

Methods: This multicenter observational study enrolled patients aged over 90 years who underwent PCI across 10 hospitals between 2011 and 2020.

Clinical Impacts of Urinary Neutrophil Gelatinase-Associated Lipocalin in Patients With Chronic Kidney Disease Undergoing Percutaneous Coronary Intervention.

Background: Chronic kidney disease (CKD) is associated with poor prognosis in patients undergoing percutaneous coronary intervention (PCI). Urinary neutrophil gelatinase-associated lipocalin (NGAL) is a biomarker for renal injury. However, the association between urinary NGAL concentrations and renal and cardiovascular events in patients with CKD undergoing PCI has not been elucidated.

Risk stratification of invasive cervical cancer diagnosed after cervical conization.

Background: Cervical intraepithelial neoplasia (CIN) diagnosis is based on colposcopy-aided histological examination. However, its accuracy in CIN diagnosis is limited. Some invasive cervical cancers (ICCs) are diagnosed after cervical conization.

Changes in fetal presentation in the preterm period and the prediction of non-cephalic delivery.

Objective: Since fetal presentation is an essential factor for planning mode of delivery, the estimation of fetal presentation at delivery is important in prenatal management. This study aimed to clarify the transition of fetal presentation during pregnancy and to propose practical strategy to predict final fetal presentation.

Methods: During the period of 2 years, fetal presentations were analyzed using ultrasonography during the prenatal visits at and after 22 weeks of gestation in a single facility.

Long-term outcomes of percutaneous revascularization for internal mammary artery-left anterior descending artery bypass failure.

Despite the excellent long-term results of internal mammary artery (IMA)-left anterior descending (LAD) bypass, percutaneous revascularization of IMA is sometimes required for IMA-LAD bypass failure. However, its clinical outcomes have not been fully elucidated. The aim of this study was to investigate the long-term clinical outcomes, including target lesion revascularization (TLR) following contemporary percutaneous revascularization of failed IMA bypass graft.

Recurrent fulminant non-rheumatic streptococcal myocarditis proven by endomyocardial biopsy and autopsy.

Unlabelled: A 42-year-old man with a history of acute myocarditis after streptococcal pharyngitis developed recurrent fulminant myocarditis. Endomyocardial biopsy revealed myocyte degeneration, interstitial edema, and neutrophil infiltration. The patient's cardiac function deteriorated rapidly, and he died despite mechanical circulatory support.

Inhibition of FGFR Reactivates IFNγ Signaling in Tumor Cells to Enhance the Combined Antitumor Activity of Lenvatinib with Anti-PD-1 Antibodies.

Combination therapies consisting of immune checkpoint inhibitors plus anti-VEGF therapy show enhanced antitumor activity and are approved treatments for patients with renal cell carcinoma (RCC). The immunosuppressive roles of VEGF in the tumor microenvironment are well studied, but those of FGF/FGFR signaling remain largely unknown. Lenvatinib is a receptor tyrosine kinase inhibitor that targets both VEGFR and FGFR.

Prognostic impact of transcardiac gradient of follistatin-like 1 reflecting hemodynamics in patients with dilated cardiomyopathy.

Background: Follistatin-like 1 (FSTL1) is a myocyte-secreted glycoprotein that could play a role in myocardial maintenance in response to harmful stimuli. We investigated the association between serum FSTL1 levels, especially focused on transcardiac gradient and the hemodynamics, to explore the prognostic impact of FSTL1 levels in patients with dilated cardiomyopathy (DCM).

Methods: Thirty-two ambulatory patients with DCM (23 men; mean age 59 years) were prospectively enrolled.

A case of reexpansion pulmonary edema and acute pulmonary thromboembolism associated with diffuse large B-cell lymphoma treated with venovenous extracorporeal membrane oxygenation.

A 37-year-old man diagnosed with diffuse large B-cell lymphoma two weeks previously, visited our emergency department with sudden dyspnea. He had a severe respiratory failure with saturated percutaneous oxygen at 80% (room air). Chest radiography showed a large amount of left pleural effusion.

Fulminant myocarditis with myositis of ocular and respiratory muscles.

A 46-year-old Japanese woman visited a nearby hospital because of diplopia after flu-like symptoms. One month later, she presented with blepharoptosis and external ophthalmoplegia. Laboratory tests showed a high creatine kinase concentration (3146 U/L).

Impact of predictive value of Fibrosis-4 index in patients hospitalized for acute heart failure.

Background: Abnormalities in liver function tests commonly occur in patients with acute heart failure (AHF). The Fibrosis-4 (FIB4) index, a non-invasive and easily calculated marker, has been used for hepatic diseases and reflects adverse prognosis. It is not clearly established whether the FIB4 index at admission can predict adverse outcomes in patients with AHF.

Associations between hemodynamic parameters at rest and exercise capacity in patients with implantable left ventricular assist devices.

Background: Hemodynamic parameters at rest are known to correlate poorly with peak oxygen uptake (VO) in heart failure. However, we hypothesized that hemodynamic parameters at rest could predict exercise capacity in patients with left ventricular assist device (LVAD), because LVAD pump rotational speed does not respond during exercise. Therefore, we investigated the relationships between hemodynamic parameters at rest (measured with right heart catheterization) and exercise capacity (measured with cardiopulmonary exercise testing) in patients with implantable LVAD.

Efficacy of Pulmonary Artery Pulsatility Index as a Measure of Right Ventricular Dysfunction in Stable Phase of Dilated Cardiomyopathy.

Background: Right ventricular dysfunction (RVD) in the setting of left ventricular (LV) myocardial damage is a major cause of morbidity and mortality, and the pulmonary artery pulsatility index (PAPi) is a novel hemodynamic index shown to predict RVD in advanced heart failure. However, it is unknown whether PAPi can predict the long-term prognosis of dilated cardiomyopathy (DCM) even in the mild to moderate phase. This study aimed to assess the ability of PAPi to stratify DCM patients without severe symptoms.

Usefulness of Plasma Branched-Chain Amino Acid Analysis in Predicting Outcomes of Patients with Nonischemic Dilated Cardiomyopathy.

The metabolism of branched-chain amino acids (BCAAs) is reported to change in heart failure (HF) and correlate with cardiac function. However, the effect of BCAAs on HF remains controversial. We investigate the prognostic value of the plasma BCAA level in nonischemic dilated cardiomyopathy (NIDCM).

Predictors of residual mitral regurgitation after left ventricular assist device implantation.

Patients with advanced heart failure often have functional mitral regurgitation. Left ventricular assist device implantation improves functional mitral regurgitation through left ventricular unloading. However, residual mitral regurgitation after left ventricular assist device implantation leads to adverse outcomes, and whether patients need concomitant mitral valve surgery is not fully elucidated.

Pathological changes of the myocardium in reworsening of anthracycline-induced cardiomyopathy after explant of a left ventricular assist device.

We herein report the long-term changes in cardiac function and pathological findings after successful explantation of a left ventricular assist device in a 42-year-old patient with anthracycline-induced cardiomyopathy with reworsening heart failure. Endomyocardial biopsy samples revealed that the cardiomyocyte diameter decreased and collagen volume fraction increased just after left ventricular assist device explantation. The collagen volume fraction decreased after 6 months, despite preserved systolic function.

Spleen size improvement in advanced heart failure patients using a left ventricular assist device.

The spleen has been recognized as an important organ that holds a reserve of 20% to 30% of the total blood volume. Spleen contraction and splenic volume reduction occur in patients with hypovolemic shock. However, the change in the spleen volume and the association between spleen size and hemodynamic parameters remain unclear in patients with advanced heart failure (HF) who need left ventricular assist device (LVAD) support.

Pulmonary artery pressure may be a predictor of closed aortic valve in patients managed by venoarterial extracorporeal membrane oxygenation.

In the management of venoarterial extracorporeal membrane oxygenation, some patients present persistently closed aortic valve. However, little is known about the variables that contribute to persistently closed aortic valve. We investigated the factors that could predict persistently closed aortic valve at the time of venoarterial extracorporeal membrane oxygenation initiation.
