Pronecroptotic Therapy Using Ceramide Nanoliposomes Is Effective for Triple-Negative Breast Cancer Cells.

Regulated necrosis, termed necroptosis, represents a potential therapeutic target for refractory cancer. Ceramide nanoliposomes (CNLs), considered potential chemotherapeutic agents, induce necroptosis by targeting the activating protein mixed lineage kinase domain-like protein (MLKL). In the present study, we examined the potential of pronecroptotic therapy using CNLs for refractory triple-negative breast cancer (TNBC), for which there is a lack of definite and effective therapeutic targets among the various immunohistological subtypes of breast cancer.

Pulmonary veno-occlusive disease after respiratory syncytial virus infection in a post hematopoietic stem cell transplantation patient.

Background: Pulmonary veno-occlusive disease (PVOD) is a rare but fatal complication of hematopoietic stem cell transplantation (HSCT). Although literature on PVOD post-HSCT is scarce, a recent study has indicated that this condition may be underestimated. Respiratory syncytial virus (RSV) is a common respiratory pathogen that causes common cold in healthy individuals but may lead to severe lower respiratory infection accompanied by respiratory distress in infants and immunocompromised individuals, such as post-HSCT patients.

Ceramide Nanoliposomes as Potential Therapeutic Reagents for Asthma.

Ceramides are an emerging class of anti-inflammatory lipids, and nanoscale ceramide-delivery systems are potential therapeutic strategies for inflammatory diseases. This study investigated the therapeutic effects of ceramide nanoliposomes (CNL) on type 2 inflammation-based asthma, induced by repeated ovalbumin (OVA) challenges. Asthmatic mice intratracheally treated with ceramide-free liposomes (Ghost) displayed typical airway remodeling including mucosal accumulation and subepithelial fibrosis, whereas, in CNL-treated mice, the degree of airway remodeling was significantly decreased.

A case of recurrent refractory cervical primary histiocytic sarcoma treated with pembrolizumab.

Histiocytic sarcoma (HS) is a rare disease with a poor prognosis. The efficacy of immune checkpoint inhibitors for this disease has not been established. A 13-year-old boy with HS refractory to conventional chemotherapy was treated with pembrolizumab, an immune checkpoint inhibitor.

Usefulness of the Trabecular Bone Score in Assessing the Risk of Vertebral Fractures in Patients with Cirrhosis.

The trabecular bone score (TBS), a surrogate measure of bone microarchitecture, provides complementary information to bone mineral density (BMD) in the assessment of osteoporotic fracture risk. This cross-sectional study aimed to determine whether TBS can identify patients with liver cirrhosis that are at risk of vertebral fractures. We enrolled 275 patients who completed evaluations for lumbar BMD, TBS, and vertebral fractures between November 2018 and April 2021.

Diagnostic challenges of primary diffuse leptomeningeal melanomatosis in early adolescence: A case report.

Introduction: Primary diffuse leptomeningeal melanomatosis is an extremely rare variant of primary melanoma of the central nervous system. It is characterized by a variety of nonspecific clinical, radiological, and histopathological features requiring differential diagnosis from a variety of diseases. Here, we aimed to use our own clinical case as an example of the difficulties in the diagnosis of this disease.

Acute Effects of Moderate Aerobic Dance Exercise on Moods, Appetite, and Energy Intake in Young Adult Women.

Energy intake (EI) has been identified as a key factor of health controlled by exercise. Aerobic dance exercise (ADEX) is a popular exercise for fitness that one can enjoy. This present study aims to examine the influence of ADEX on moods, appetite, and EI.

Usefulness of nutritional therapy recommended in the Japanese Society of Gastroenterology/Japan Society of Hepatology evidence-based clinical practice guidelines for liver cirrhosis 2020.

Background: The JSGE/JSH guidelines for the management of patients with liver cirrhosis revised in 2020 recommends new strategies for nutritional assessment and intervention, although their usefulness in daily clinical practice is unclear.

Methods: A total of 769 patients with cirrhosis were classified into low-, intermediate-, and high-risk groups according to hypoalbuminemia and sarcopenia, the criteria established for initiating the nutritional therapy algorithm in the guidelines. The association between these groups and mortality was analyzed using a Cox proportional hazards model.

Usefulness of the Stroop Test in Diagnosing Minimal Hepatic Encephalopathy and Predicting Overt Hepatic Encephalopathy.

Minimal hepatic encephalopathy (MHE) adversely affects the clinical outcomes of patients with liver cirrhosis. This prospective study aimed to evaluate the utility of the Stroop test in the diagnosis of MHE and prediction of overt hepatic encephalopathy (OHE) in Japanese patients with cirrhosis. We enrolled 152 patients who underwent the Stroop test between November 2018 and February 2020.

Handgrip strength stratifies the risk of covert and overt hepatic encephalopathy in patients with cirrhosis.

Background: Handgrip strength (HGS) is a simple and convenient method to assess nutrition status in patients with cirrhosis. This retrospective study aimed to investigate the utility of HGS for predicting patients with covert hepatic encephalopathy (CHE) and patients at high risk of overt hepatic encephalopathy (OHE).

Methods: We reviewed 963 patients with cirrhosis and consequently enrolled eligible 270 patients.

Zinc deficiency predicts overt hepatic encephalopathy and mortality in liver cirrhosis patients with minimal hepatic encephalopathy.

Aim: Minimal hepatic encephalopathy (MHE) is associated with poor outcomes and the development of overt hepatic encephalopathy (OHE) in patients with liver cirrhosis (LC). Zinc plays a key role in the detoxification of ammonia, a risk factor of hepatic encephalopathy. This study aimed to investigate whether zinc deficiency predicts OHE occurrence and mortality in LC patients with MHE.

Aggressive growing of the infantile cavernous hemangioma of the calvaria: a case report and review of literature.

Introduction: Primary intraosseous cavernous hemangiomas of the skull are very rare in the pediatric age group and usually slow-growing tumors.

Case Report: We present a case of 5-month-old girl with a left occipital cavernous hemangioma that is rapidly growing. The subcutaneous occipital tiny mass was first noted at birth, and the lesion became rapidly enlarged in size and became soft for 3 months.

Net-400-Gbps PS-PAM transmission using integrated AMUX-MZM.

Simple high-speed optical transmission technologies are desired for use in intra-and inter-datacenter networks. In this study, we demonstrate simple single-carrier intensity-modulated direct-detection (IMDD) transmissions at a net data rate of 400 Gbps (516.7 Gbps gross) over 20 km with a compact transmitter subassembly.

Biallelic TBCD Mutations Cause Early-Onset Neurodegenerative Encephalopathy.

We describe four families with affected siblings showing unique clinical features: early-onset (before 1 year of age) progressive diffuse brain atrophy with regression, postnatal microcephaly, postnatal growth retardation, muscle weakness/atrophy, and respiratory failure. By whole-exome sequencing, we identified biallelic TBCD mutations in eight affected individuals from the four families. TBCD encodes TBCD (tubulin folding co-factor D), which is one of five tubulin-specific chaperones playing a pivotal role in microtubule assembly in all cells.

Transient Deformation of Neutrophils in Kawasaki Disease.

In the treatment of Kawasaki disease, resistance to high-dose immunoglobulin intravenous (IGIV) can occur. The neutrophil morphology analyses in 17 patients revealed that transient pseudo-Pelger-Huët anomaly was more frequently detected in the IGIV-resistant group. This finding may aid the prediction of IGIV resistance.

Discordant clinical phenotype in monozygotic twins with Alagille syndrome: Possible influence of non-genetic factors.

Alagille syndrome is a multisystem developmental disorder characterized by bile duct paucity, congenital heart disease, vertebral anomalies, posterior embryotoxon, and characteristic facial features. Alagille syndrome is typically the result of germline mutations in JAG1 or NOTCH2 and is one of several human diseases caused by Notch signaling abnormalities. A wide phenotypic spectrum has been well documented in Alagille syndrome.
