Psoriasiform Dermatitis Following Kawasaki Disease: A Case Report and Literature Review.

Kawasaki disease (KD) is an idiopathic acute inflammatory illness that commonly affects children in Northeast Asian countries. In this case report, a psoriasiform eruption appeared on the face and extremities following the onset of KD. A review of previous reports identified 38 cases of psoriasiform eruptions following KD, typically appearing 4 days to 2 months after the onset of KD, unlike other skin manifestations associated with the disease.

Neuronal substance P-driven MRGPRX2-dependent mast cell degranulation products differentially promote vascular permeability.

Mas-related G protein-coupled receptor b2 (Mrgprb2) binding to its cationic endogenous and exogenous ligands induces mast cell degranulation and promotes inflammation in mice. However, the physiological roles of its human homologue MRGPRX2 remain unclear. Here we aimed to elucidate the mechanisms by which MRGPRX2 regulates vascular permeability, and generated MRGPRX2 knock-in (MRGPRX2-KI) and Mrgprb2 knockout (Mrgprb2-KO) mice.

Focusing on Sedentary Behavior in Comprehensive Cardiac Rehabilitation.

In recent years, the adverse effects of prolonged sedentary behavior in daily life, so-called 'sitting too much', on health have been pointed out. Sedentary behavior is defined as 'all waking behavior in which the energy expenditure in a sitting, semi-recumbent, or recumbent position is 1.5 metabolic equivalents or less'.

Increased response to granulocyte-macrophage colony-stimulating factor in peripheral blood cells and transient manifestations mimicking juvenile myelomonocytic leukemia in a male patient with NEMO deficiency caused by a deep intronic pathogenic variant of IKBKG.

X-linked NF-κB essential modulator (NEMO) deficiency is a primary immunodeficiency characterized by combined immunodeficiency and ectodermal dysplasia. Monocytes from the patients demonstrate a severely impaired response to tissue necrosis factor or lipopolysaccharide, whereas hyper-inflammation is found in some patients. Juvenile myelomonocytic leukemia (JMML) is a pediatric malignancy caused by hypersensitivity to granulocyte-macrophage colony-stimulating factor (GM-CSF) and aberrant RAS signaling activation.

A Non-targeted Proteomics Newborn Screening Platform for Inborn Errors of Immunity.

Purpose: Newborn screening using dried blood spot (DBS) samples for the targeted measurement of metabolites and nucleic acids has made a substantial contribution to public healthcare by facilitating the detection of neonates with genetic disorders. Here, we investigated the applicability of non-targeted quantitative proteomics analysis to newborn screening for inborn errors of immunity (IEIs).

Methods: DBS samples from 40 healthy newborns and eight healthy adults were subjected to non-targeted proteomics analysis using liquid chromatography-mass spectrometry after removal of the hydrophilic fraction.

Efficacy of steroid therapy for improving native liver survival after pediatric acute liver failure with immune activation.

Aim: Recent evidence suggests that acute liver failure (ALF) in some patients may reflect a dysregulated immune response, and that corticosteroids improve survival of the native liver in ALF patients with high serum alanine aminotransferase levels, which are an indication of liver inflammation. However, it is unclear whether steroids are effective for pediatric acute liver failure (PALF). The aim of this retrospective case-control study is to examine whether steroid therapy for PALF accompanied by immune activation improves the survival of native liver and to identify factors that predict responses to steroid treatment.

Contamination-Free Reference Electrode Using Prussian Blue for Small Oxygen Sensors.

In recent years, significant attention has been directed toward advancing compact, point-of-care testing (POCT) devices to better deliver patient care and alleviate the burden on the medical care system. Common POCTs, such as blood oxygen sensors, leverage electrochemical sensing in their design. However, conventional electrochemical devices typically use Ag/AgCl reference electrodes, which are likely to release trace amounts of silver ions that contaminate the working electrode, causing rapid deterioration of the devices.

Lymphocyte-to-C-reactive protein ratio and score in patients with heart failure: Nutritional status, physical function, and prognosis.

Aims: In heart failure (HF), inflammation is linked to malnutrition and impaired physical function. In this study, we aimed to assess how novel nutritional-inflammatory markers and lymphocyte-to-C-reactive protein ratio (LCR) and score (LCS) are associated with the nutritional status, physical function, and prognosis of patients with HF.

Methods And Results: This study was a secondary analysis of the FRAGILE-HF study, a prospective observational study conducted across 15 hospitals in Japan.

Effects of cardiac rehabilitation on cognitive function in patients with acute coronary syndrome: A systematic review.

Background: Construction of an intervention method for the cognitive dysfunction of patients with acute coronary syndrome (ACS) is needed. Exercise-based comprehensive cardiac rehabilitation is a potentially effective approach that can improve cognitive function in ACS patients. This study aimed to investigate the effect of cardiac rehabilitation on cognitive function in ACS patients through a systematic review.

NLRP1 inflammasome promotes senescence and senescence-associated secretory phenotype.

Background: Senescence is a cellular aging-related process triggered by different stresses and characterized by the secretion of various inflammatory factors referred to as senescence-associated secretory phenotype (SASP), some of which are produced by the NLRP3 inflammasome. Here, we present evidence that the NLRP1 inflammasome is a DNA damage sensor and a key mediator of senescence.

Methods: Senescence was induced in fibroblasts in vitro and in mice.

Sedentary behaviour may cause differences in physical outcomes and activities of daily living in older cardiovascular disease patients participating in phase I cardiac rehabilitation.

This study aimed to investigate the rate of sedentary behaviour and differences in physical outcomes and activities of daily living (ADL) based on sedentary behaviour time of hospitalized older cardiovascular disease patients undergoing phase I cardiac rehabilitation. Older cardiovascular disease patients were enrolled from October 2020 to September 2023 and were divided into the high sedentary behaviour group (≥ 480 min/day) and low sedentary behaviour group (< 480 min/day). Patients' clinical characteristics, usual gait speed, and Five Times Sit to Stand Test time were compared as indices of physical outcomes.

Intranasal administration of ceramide liposome suppresses allergic rhinitis by targeting CD300f in murine models.

Allergic rhinitis (AR) is caused by type I hypersensitivity reaction in the nasal tissues. The interaction between CD300f and its ligand ceramide suppresses immunoglobulin E (IgE)-mediated mast cell activation. However, whether CD300f inhibits the development of allergic rhinitis (AR) remains elusive.

Effects of Group Exercise Intervention on Quality of Life and Physical Parameters in Patients with Childhood Cancer: A Systematic Review.

Background: Although the survival rates of childhood cancer are increasing, children diagnosed as having cancer experience psychological and physical problems and a declining quality of life (QOL).

Methods: A systematic review of PubMed databases was conducted up to September 2023 to identify studies reporting the effects of group exercise intervention in children with cancer. The inclusion criteria were pre-specified, including children aged ≤19 years old who received group exercise intervention and interventional studies written in English.

Fluorine materials scavenge excess carbon dioxide and promote Escherichia coli growth.

Fluorinated solvents have been used as oxygen carriers in closed microbial cultures to sustain aerobic conditions. However, the growth-promoting effects of fluorinated solvents remain unclear. Therefore, this study aimed to elucidate the mechanism by which fluorinated solvents promote microbial growth and to explore alternative materials that can be easily isolated after culture.

Effects of self-monitoring using an accelerometer on physical activity of older people with long-term care insurance in Japan: a randomized controlled trial.

Purpose: This study aimed to investigate the effects of a self-monitoring intervention to promote an increase in physical activity, as measured by step count, and reduce sedentary behavior in older people covered by the long-term care insurance system (LTCI) in Japan.

Methods: This was a randomized controlled trial conducted at a daycare center from October 2022 to January 2023. Fifty-two older adults with LTCI who were able to walk with or without aids were assigned to an intervention (n = 26) group and control (n = 26) group.
