Although thrombocytopenia, anasarca, fever, reticulin fibrosis/renal failure, and organomegaly (TAFRO) syndrome was first reported in 2010, its pathogenesis and prognosis are still unknown. Moreover, reports on rehabilitation in patients with TAFRO are limited. In severe cases, dyspnea and muscle weakness could impede improvements in activities of daily living (ADL). However, reports on exercise intensity showed no worsening of TAFRO within the load of 11-13 on the Borg scale. Herein, we describe the rehabilitation and progress in a 61-year-old woman with TAFRO syndrome complicated by cerebral infarction from early onset to discharge...

BACKGROUND: Previously, we revealed that co-administration of particular enteral nutrients (ENs) decreases plasma concentrations and gastric absorption of phenytoin (PHT), an antiepileptic drug, in rats; however, the mechanism has not been clarified. METHODS: We measured the permeability rate of PHT using a Caco-2 cell monolayer as a human intestinal absorption model, with casein, soy protein, simulated gastrointestinal digested casein or soy protein, dextrin, sucrose, degraded guar-gum, indigestible dextrin, calcium, and magnesium, which are abundant in the ENs, and also measured the solution's properties...

Short-chain peptides derived from various protein sources have been shown to exhibit diverse bio-modulatory and health-promoting effects in animal experiments and human trials. We recently reported that the oral administration of the Tyr-Trp (YW) dipeptide to mice markedly enhances noradrenaline metabolism in the brain and ameliorates the working-memory deficits induced by the β-amyloid 25-35 peptide (Aβ25-35 ). In the current study, we performed multiple bioinformatics analyses of microarray data from Aβ25-35 /YW-treated brains to determine the mechanism underlying the action of YW in the brain and to infer the molecular mechanisms and networks involved in the protective effect of YW in the brain...

Despite the dramatic success of immune checkpoint blockers in treating numerous cancer cell types, current therapeutic modalities provide clinical benefits to a subset of patients with cervical cancers. CD47 is commonly overexpressed in a broad variety of cancer cells, correlates with poor clinical prognosis, and acts as a dominant macrophage checkpoint by interacting with receptors expressed on macrophages. It allows cancer cells to escape from the innate immune system and hence is a potential therapeutic target for developing novel macrophage checkpoint blockade immunotherapies...

BACKGROUND: In myelodysplastic syndromes (MDS), in addition to disease-related symptoms, many adverse events are associated with anticancer agents, myeloablative conditioning (MAC), and allogeneic hematopoietic stem cell transplantation (allo-HSCT). Isolation and bed rest in a clean room severely limit physical activity, resulting in cardiopulmonary and muscle weakness. In addition, post-transplant patients may experience general fatigue, gastrointestinal symptoms, and infections associated with a weakened immune system, as well as graft-versus-host disease, which causes further decline in physical function and activities of daily living (ADL)...

In the past decade, immune checkpoint inhibitors have exhibited potent antitumor efficacy against multiple solid malignancies but limited efficacy against pancreatic ductal adenocarcinoma (PDAC). Cluster of differentiation (CD) 47, a member of the immunoglobulin G superfamily, is overexpressed in the surface membrane of PDAC and independently correlates with a worse clinical prognosis. Furthermore, CD47 functions as a dominant macrophage checkpoint, providing a potent "do not eat me" signal to enable cancer cells to evade the innate immune system...

BACKGROUND: Chagas disease or American trypanosomiasis, a neglected tropical disease, is a persistent Public Health problem in Latin America and other, non-endemic, countries. Point-of-care (POC) sensitive methods are still needed to improve and extend early diagnosis in acute infections such as congenital Chagas disease. The objective of this study was to analytically evaluate in the lab the performance of a qualitative POC molecular test (Loop-mediated isothermal amplification (LAMP), Eiken, Japan) for rapid diagnosis of congenital Chagas disease employing FTA cards or Whatman 903 filter paper as solid supports for small-scale volumes of human blood...

A man in his 70s was admitted to our hospital due to jaundice and upper abdominal pain. Laboratory findings indicated elevated serum hepatobiliary enzyme and amylase levels. Contrast-enhanced computed tomography revealed smooth wall thickening of the terminal bile duct (tBD) with a faintly enhanced inner line. ERCP revealed stenosis from the tBD to the ampulla of Vater (AV) with upstream dilatation. Intraductal ultrasound (IDUS) circumferentially revealed a thickened wall preserving a three-layered structure throughout the same region...

Government campaigns to replace off-patent brand pharmaceuticals with low cost generic products in national health insurance systems have apparently increased their production in the last two decades in Japan. The contamination of a batch of generic itraconazole tablets with the sleep inducer rilmazafone caused significant adverse events and related accidents in 2020, amidst increasing use of the generic products in healthcare. Investigations revealed many Good Manufacturing Practice (GMP) violations and other evidence of poor quality management in the manufacturing/marketing authorization holder (MAH)...

Treatment of esophageal cancer is based on tumor-node-metastasis (TNM) classification, and surgical treatment is chosen based on the patient's ability to tolerate surgery. Surgical endurance partly depends on activity status, with performance status (PS) generally used as an indicator. This report describes a 72-year-old man with lower esophageal cancer and an 8-year history of severe left hemiplegia. He had sequelae of cerebral infarction and a TNM classification of T3, N1, and M0, and was judged ineligible for surgery because his PS was grade three; he underwent preoperative rehabilitation with hospitalization for 3 weeks...

The model core curriculum for pharmacy education and professional standards for pharmacists established by the Japan Pharmaceutical Association aim to inculcate knowledge and skills on basic life support (BLS) and ensure that pharmacy students are well equipped with knowledge on BLS. In this study, pharmacy students were enrolled in the PUSH course, a BLS training course for citizens, and a questionnaire survey was conducted before and after the course to evaluate the change in students awareness about BLS and overall satisfaction with the course...

The obturator nerve originates from the lumbar plexus and innervates sensation in the thigh and movement of the adductor muscle group of the hip. Reports on physical therapy for patients with obturator nerve injuries have been limited due to insufficient injuries, and there have been no reports on rehabilitation after neurotmesis. Furthermore, there are no reports on the status of activities of daily living (ADL) and details of physical therapy in patients with paralysis of the adductor muscle group. In this study, we reported on a patient with adductor paralysis due to obturator neurotmesis, including the clinical symptoms, characteristics of ADL impairment, and effective movement instruction...

Control of cutaneous circulation is critically important to maintain thermoregulation, especially in individuals with cervical spinal cord injury (CSCI) who have no or less central thermoregulatory drive. However, the peripheral vasoconstrictor mechanism and capability have not been fully investigated after CSCI. Post- and presynaptic sensitivities of the cutaneous vasoconstrictor system were investigated in 8 CSCI and 7 sedentary able-bodied (AB) men using an intradermal microdialysis technique. Eight doses of norepinephrine (NE, 10-8 to 10-1 M) and 5 doses of tyramine (TY, 10-8 , 10-5 to 10-2 M) were administered into the anterior right and left thigh, respectively...

Sickle cell disease (SCD) is a heritable disorder caused by β-globin gene mutations. Induction of fetal γ-globin is an established therapeutic strategy. Recently, epigenetic modulators, including G9a inhibitors, have been proposed as therapeutic agents. However, the molecular mechanisms whereby these small molecules reactivate γ-globin remain unclear. Here we report the development of a highly selective and non-genotoxic G9a inhibitor, RK-701. RK-701 treatment induces fetal globin expression both in human erythroid cells and in mice...

Animal testing of cosmetic ingredients and products has been banned in the European Union since 2013. However, in Japan, the application of new quasi-drugs requires the generation of data on acute oral toxicity through animal testing. A weight of evidence approach for assessing oral toxicity was challenged. This approach used a combination of safety data, including a neutral red uptake cytotoxicity assay using BALB/c3T3 cells (3T3-NRU cytotoxicity assay), which can assess the acute oral toxicity of quasi-drugs or cosmetic ingredients...

BACKGROUND: Hepatectomy, the most common treatment for hepatocellular carcinoma, is associated with greater intraoperative blood loss than is resection of other malignancies. The effect of blood product transfusion (red blood cell [RBC], platelet, fresh frozen plasma [FFP], 5 and 25% albumin) on prognosis remains unclear. This study examined effects of blood product transfusion on prognoses of patients who underwent hepatectomy for hepatocellular carcinoma. METHODS: We included 2015 patients with pathologically confirmed hepatocellular carcinoma who underwent hepatectomy at our institution during 1990-2019...

Objectives: Ergometer exercise was considered a new loading method that can be used for participants who are unable to assume the core strengthening exercise posture commonly used to strengthen the erector spinae and multifidus. This study aimed to investigate with healthy participants whether arm and leg ergometers could be used for core strengthening exercises and whether different exercise sites would affect the results. Methods: The study was conducted with 15 healthy adult male participants aged 20-35 years...

Patients with pancreatic cancer (PC) often suffer from refractory ascites associated with peritoneal metastasis. This severely impairs activities of daily living and leads to an unfavorable prognosis. Cell-free and concentrated ascites reinfusion therapy (CART) has attracted attention as a promising therapy for relieving the symptoms of malignant ascites. Accumulating evidence suggests that malignant ascites contains a variety of soluble factors, such as cytokines, that can be beneficial or detrimental in the prognosis of patients with refractory ascites...

Recently, we reported that extent of proliferation of atypical hepatocytes (atypical hepatocytes) was most important histological risk factor for development of hepatocellular carcinoma (HCC) from chronic hepatitis C or liver cirrhosis. Here, we aimed to clarify whether the atypical hepatocytes in noncancerous sections is also involved in postoperative recurrence. Furthermore, we investigated significant genes involved in the atypical hepatocytes. Association between the extent of atypical hepatocytes in noncancerous tissue and postoperative recurrence was validated in 356 patients with HCC...
