Population Using Tobacco for Pain Relief: A Preliminary Cross-Sectional Study in Japan.

Background: There is a complex relationship between tobacco use and pain. Nicotine provides temporary pain relief but increases the risk of chronic pain. This study aimed to investigate use of tobacco for pain relief and its association with demographic and medical characteristics in Japan.

ATG9A facilitates the closure of mammalian autophagosomes.

Canonical autophagy captures within specialized double-membrane organelles, termed autophagosomes, an array of cytoplasmic components destined for lysosomal degradation. An autophagosome is completed when the growing phagophore undergoes ESCRT-dependent membrane closure, a prerequisite for its subsequent fusion with endolysosomal organelles and degradation of the sequestered cargo. ATG9A, a key integral membrane protein of the autophagy pathway, is best known for its role in the formation and expansion of phagophores.

A Phase II, Open Label, Single-Arm Study on the Efficacy of Cabozantinib in Patients With Advanced/Metastatic Nonsmall Cell Lung Cancer Harboring MET Exon 14 Alterations who Developed Acquired Resistance to Tepotinib or Capmatinib (CAPTURE Trial).

Background: MET gene exon 14 skipping was identified as a potential driver mutation that occurs in approximately 3%-4% of patients with nonsmall cell lung cancer (NSCLC), typically in the absence of other driver mutations. Capmatinib and tepotinib were the first MET- tyrosine kinase inhibitors (MET-TKIs) approved by the FDA and PMDA, specifically for patients with metastatic NSCLC. Several studies have reported acquired resistance after MET-TKI treatment for MET mutation-positive NSCLC.

Adverse reactions to mRNA COVID-19 vaccine in people with allergies in Japan.

mRNA vaccines emerged as a new therapeutic modality during the COVID-19 pandemic. Individuals with allergies often experience anxiety about potential adverse reactions to these vaccines. This study aims to elucidate the relationship between adverse reactions and various allergies, asthma, or atopic disorders.

Immaturity of gut functions and induction of tolerance during early infancy.

Tolerance to foreign molecules is primarily induced through three pathways: anergy, active suppression, and clonal deletion. The immaturity of gut functions, including digestion and barrier protection against foreign molecules during early infancy, is closely linked to the induction of tolerance. A significant number of undigested peptides can pass through leaky gut walls during this period, making it an opportune time to introduce active suppression and clonal deletion in the intestine.

Characterization of breast cancer tumors in older patients who show de novo resistance to endocrine therapy.

The standard treatment for hormone receptor-positive breast cancer in good general condition is curative surgery followed by endocrine therapy. However, for older patients, endocrine therapy alone is sometimes chosen instead of curative surgery due to health conditions or personal preference, though this is not yet a standard approach. It is crucial to develop elderly-specific treatment strategies, potentially establishing endocrine therapy alone as a standard option.

NS1 binding protein regulates stress granule dynamics and clearance by inhibiting p62 ubiquitination.

The NS1 binding protein, known for interacting with the influenza A virus protein, is involved in RNA processing, cancer, and nerve cell growth regulation. However, its role in stress response independent of viral infections remains unclear. This study investigates NS1 binding protein's function in regulating stress granules during oxidative stress through interactions with GABARAP subfamily proteins.

Methods And Results: In this post-hoc analysis of the ILLUMINATE-CS (ILLUstration of the Management and prognosIs of JapaNese pATiEnts with Cardiac Sarcoidosis), which is a multicentre retrospective observational study, we analysed 103 patients (62.2 ± 10.

Health Utility of Pain Response Versus Nonresponse to Palliative Radiation Therapy for Symptomatic Bone Metastases: Analyses Based on Real-World Data from 26 Centers.

Utility values of responders and nonresponders are essential inputs in cost-effectiveness studies of radiation therapy for painful bone metastases but, to our knowledge, they have not been reported separately. We sought to determine the utility values of responders and nonresponders using data from a prospective observational study on bone metastases. The original prospective observational study was conducted at 26 centers in Japan.

Targeting senescent cells for the treatment of age-associated diseases.

Cellular senescence, which entails cellular dysfunction and inflammatory factor release-the senescence-associated secretory phenotype (SASP)-is a key contributor to multiple disorders, diseases, and the geriatric syndromes. Targeting senescent cells using senolytics has emerged as a promising therapeutic strategy for these conditions. Among senolytics, the combination of dasatinib and quercetin (D + Q) was the earliest and one of the most successful so far.

The role of sonic hedgehog signaling in the oropharyngeal epithelium during jaw development.

Sonic hedgehog (Shh) is expressed in the oropharyngeal epithelium, including the frontonasal ectodermal zone (FEZ), which is defined as the boundary between Shh and Fgf8 expression domains in the frontonasal epithelium. To investigate the role of SHH signaling from the oropharyngeal epithelium, we generated mice in which Shh expression is specifically deleted in the oropharyngeal epithelium (Isl1-Cre; Shh). In the mutant mouse, Shh expression was excised in the oropharyngeal epithelium as well as FEZ and ventral forebrain, consistent with the expression pattern of Isl1.

Cost-effectiveness of ferric citrate hydrate in patients with iron deficiency anemia.

We investigated the cost-effectiveness of treating iron deficiency anemia (IDA) with ferric citrate hydrate (FC) in Japan. We employed four treatment strategies: switching from sodium ferrous citrate (SF) to FC at (1) 500 mg (approximately 120 mg of iron) per day or (2) 1000 mg (approximately 240 mg of iron) per day in patients with SF-induced nausea/vomiting, or starting treatment with FC at (3) 500 mg/day or (4) 1000 mg/day. We evaluated the cost-effectiveness of these strategies compared with SF 100 mg (100 mg of iron) per day.

The transition of the criteria for disseminated intravascular coagulation and the targeted patients in randomized controlled trials over the decades: a scoping review.

Background: Disseminated intravascular coagulation (DIC) is a severe complication in septic patients. The Japanese Ministry of Health and Welfare (JMHW)-DIC criteria, the first DIC criteria, were established in 1983, and several other criteria have been proposed since then, including the International Society on Thrombosis and Haemostasis (ISTH)-overt DIC criteria and the Japanese Association for Acute Medicine (JAAM) DIC criteria. This study aimed to look into the transition of DIC criteria used in randomized controlled trials (RCTs) for sepsis-induced DIC.

Elucidation of the clinical traits of diabetic chorea through a questionnaire survey of people with diabetic chorea from 59 Japanese hospitals.

Aims: Diabetic chorea refers to sudden involuntary movements developing in people with diabetes mellitus and is known to occur mainly in those with severe hyperglycemia. We conducted a questionnaire survey of case-reporting facilities in Japan to elucidate their clinical characteristics.

Methods: We searched the PubMed and Ichushi databases for case reports published from January 1, 2012, to December 31, 2017, using "diabetes" and "chorea" as keywords, and sent a questionnaire to the reporting institutions.

Efficacy and Safety of Sodium Zirconium Cyclosilicate in the Management of Hyperkalemia in Patients with Heart Failure with Reduced and Mildly Reduced Ejection Fraction and Chronic Kidney Disease Treated with Spironolactone: rational for and design of the REGISTA-K trial.

Background: To evaluate whether sodium zirconium cyclosilicate (SZC) enables the uptitration of spironolactone without increasing the risk of hyper- and hypokalemia in patients with heart failure with reduced and mildly reduced ejection fraction (HFrEF and HFmrEF) and moderate/severe chronic kidney disease (CKD) who developed hyperkalemia during treatment with suboptimal spironolactone dose.

Methods: The REGISTA-K is a randomized, double-blind, placebo-controlled, multicenter trial that examined the efficacy and safety of SZC in uptitrating spironolactone without the occurrence of hyperkalemia or hypokalemia. A total of 266 patients with HFrEF and HFmrEF and hyperkalemia will be randomized in a 1:1 ratio to receive either SZC or placebo after treating hyperkalemia with SZC at 25 sites in Japan.

Dantrolene inhibition of ryanodine receptor 1 carrying the severe malignant hyperthermia mutation Y522S visualized by cryo-EM.

Mutations in the skeletal isoform of the ryanodine receptor 1 (RyR1) pose grave risks during anesthesia or treatment with succinylcholine muscle relaxants. These can trigger a potentially lethal malignant hyperthermia (MH) episode via intracellular calcium increase mainly from RyR1 channel leakage. Dantrolene is the only known treatment option to prevent death.

Investigation of predictors of latent visual impairment in patients with sellar lesions.

Objective: Patients with sellar lesions compressing the optic nerve sometimes perceive visual improvement after lesion resection, despite the absence of visual impairment on preoperative ophthalmological examination. This study investigated the indicators of latent visual impairment in patients with sellar lesions.

Methods: Forty-five patients who underwent surgery for sellar lesions compressing the optic nerve with no preoperative visual abnormalities and no change in visual assessment between pre- and postoperative ophthalmological examinations were divided into two groups: 1) patients who perceived recovery of visual function after lesion resection (the improved group), and 2) patients who did not (the unaffected group).
