An exploration of the psychometric properties of the SATAQ-4 among adolescent boys in Japan.

Eat Behav 2018 Dec 6;32:31-36. Epub 2018 Dec 6.

Department of Psychology, University of South Florida, Tampa, FL, USA.

Research among Western adult and adolescent males suggests that sociocultural influences are implicated in the drive for muscularity and weight-change behaviors. However, few studies have examined these relationships among adolescent boys from non-Western backgrounds. The current study sought to assess the psychometric properties of the Sociocultural Attitudes Towards Appearance Questionnaire-4 (SATAQ-4), a 22-item, 5-factor measure of sociocultural influence on appearance ideals, among Japanese (n = 984) adolescent boys.

Feasibility of transcatheter prosthetic paravalvular leakage closure: a single-center, exploratory safety evaluation study of transcatheter closure of prosthetic paravalvular regurgitation in Japan (STOP PARA study).

Gen Thorac Cardiovasc Surg 2018 Dec 14. Epub 2018 Dec 14.

Department of Cardiovascular Surgery, National Cerebral and Cardiovascular Center, Suita, Japan.

Objective: The standard treatment of prosthetic paravalvular leakage (PVL) accompanied by heart failure or hemolytic anemia is repeat open surgery. Although favorable outcomes for transcatheter prosthetic PVL closure in patients with a high surgical risk for repeat open surgery have been reported, procedural feasibility has not been examined in Japan.

Methods: From March 2015 to November 2015, transcatheter PVL closure in mitral position was performed in four patients (age range 41-78, three females) with high surgical risk due to history of repeated surgeries, chest radiation and reconstruction of the mitral annulus after debridement of abscess owing to infective endocarditis.

Immunohistochemical evaluation of tumor budding for stratifying T1 colorectal cancer: optimal cut-off value and a novel computer-assisted semiautomatic method.

Mod Pathol 2018 Dec 14. Epub 2018 Dec 14.

Division of Pathology, The Cancer Institute; Department of Pathology, The Cancer Institute Hospital, Japanese Foundation for Cancer Research, Tokyo, 135-8550, Japan.

High-grade tumor budding is an adverse prognostic factor for submucosal invasive (T1) colorectal cancer used to predict the risk for lymph node metastasis in endoscopically resected specimens. Cytokeratin immunohistochemistry is a potential option for evaluating tumor budding. The optimal cut-off value between low- and high-grade budding has not yet been determined, however, and the high inter-observer variability in selecting budding foci remains problematic. Read More

Link of negative core beliefs about the self with perceived dysfunctional parenting.

Psychiatry Res 2018 Dec 25;270:715-719. Epub 2018 Oct 25.

Department of Psychiatry, Yamagata University School of Medicine, 2-2-2 Iidanishi, Yamagata 990-9585, Japan.

Cognitive theory posits the central role of negative core beliefs about the self in cognitive vulnerabilities to depression, and this position is supported by empirical studies. It is also hypothesized that these core beliefs develop as a result of negative interactions with significant others in early life. To test the hypothesis that negative core beliefs about the self are formed by dysfunctional parenting, we examined their relations with perceived parental rearing. Read More

Molecular basis for the potential role of GRK2 in pathological disorders.

Nihon Rinsho 2016 Oct;74(10):1761-1768

G protein-coupled receptor kinase 2(GRK2) is a ubiquitous member of the family of GRKs that are serine/threonine kinases originally discovered for their role in the process of desensitization of agonist-activated G protein-coupled receptors (GPCRs). However, emerging evidence suggests that GRK2 can phosphorylate a large number of non-GPCR substrates and interact with a plethora of proteins involved in signaling and trafficking, suggesting that GRK2 would participate in the regulation of diverse cellular responses in a phosphorylation-dependent and -independent manner. Alternations in GRK2 levels and/or activity are demonstrated in an array of relevant cardiovascular, metabolic, inflammatory, or cancer pathologies. Read More

Mind-body inter-relationship of bronchial asthma.

Nihon Rinsho 2016 Oct;74(10):1756-1760

The mind-body inter-relationship of bronchial asthma and its pathological mechanisms have been clarified by the knowledge obtained from basic research studies, such as epide- miological investigations, animal experiments, and brain imaging studies. It is important to take advantage of the knowledge obtained from these researches to clarify the pathology of bronchial asthma and to extend the results to the clinical sphere by developing effective treatments. In the clinical setting, the 'Japanese Guidelines for the Diagnosis and Treatment of Psychosomatic Diseases' is useful for the assessment and treatment of bronchial asthma accompanied by psychosomatic related problems.

Current status and tasks of the patient education in asthma.

Authors:
Yotaro Takaku

Nihon Rinsho 2016 Oct;74(10):1751-1755

With a chronic disease such as asthma, it is important for patients to be provided with education and skills in order to effectively manage their asthma. Although the principal knowl- edge may be the same, it should be adjusted for individual patient and care should be taken so that patients can be socially and mentally active. The following items should be taught; namely the fact that asthma is a chronic disease that requires long-term management, dif- ferences between relievers and controllers, the usage of inhalers, self-monitoring of symp- toms with a diary and peak flow monitoring, a self-management plan (an action plan to show how to recognize and respond to worsening asthma), and avoidance of environmental allergens.

Authors:
Satoshi Konno

Nihon Rinsho 2016 Oct;74(10):1729-1734

Asthma and chronic obstructive pulmonary disease (COPD) are obstructive pulmonary diseases characterized by chronic airway inflammation. Historically, the pathogenesis of the two diseases has been independently studied in mutually exclusive populations. However, the recent recognition of heterogeneity and of the importance of phenotypic classification in both diseases have highlighted the need to pay much attention to subjects with overlapping features of both asthma and COPD: those with asthma-COPD overlap syndrome (ACOS).

New drugs for asthma; current status and future perspectives.

Nihon Rinsho 2016 Oct;74(10):1709-1714

In most asthmatic patients, asthma symptoms can be well controlled through the pharmaco- logical interventions using combination with inhaled corticosteroids(ICSs) and/long-acting beta2-agonists(LABA) inhalers. However, there are some severe cases who did not respond to the current asthma therapy. One of topic of development for new asthma drugs is molecular targeting therapy such as anti-Th2-cytokine antibody and chemoattractant recep- tor-homologous molecule expressed on Th2 cells (CRTH2) inhibitors.

Perioperative management for patients with bronchial asthma.

Nihon Rinsho 2016 Oct;74(10):1698-1702

To minimize the risks of perioperative respiratory complications in patients with asthma undergoing general anesthesia, the key is detailed preoperative assessment of asthmatic patients. A patient with a history of frequent exacerbations, aspirin-exacerbated respiratory disease, or recent airway infection has a severe risk of perioperative exacerbation. Pre- operative intervention with anti-inflammatory and bronchodilatory medication should be considered if asthma is poorly controlled before surgery. Read More

Severe persistent asthma has been defined as being symptomatic every day with distur- bance of daily life. To judge asthma as severe and intractable, besides misdiagnosis, treatment step 4 has been properly done with good adherence, appropriate management of comorbidi- ties, avoidance of risk factors. Management for severe intractable asthma consists of thera- peutic step 4 with adjustment of the dose of sustained release theophylline by a step-wise manner with therapeutic dose monitoring, and selection of ICS or ICS/LABA considering individual state, and selecting intermittent administration of OCS and/or anti-IgE(omali- zumab) or anti-IL-5 (mepolizumab) antibodies after getting informed consent from a patient.

Radiologic finding of bronchial asthma.

Nihon Rinsho 2016 Oct;74(10):1634-1639

High-resolution computed tomography (HRCT) scan is a noninvasive technique that might be valuable for evaluating bronchial wall thickening and bronchiectasis as a result of chronic inflammation in patients with severe asthma. HRCT is also useful to diagnose the complications of asthma such as pulmonary emphysema and chronic eosinophilic pneumonia. In addition, HRCT will be able to demonstrate the tracheobronchial and parenchymal abnormality dis- tinctly, with the result that it will be helpful for making differential diagnosis in the patients with wheeze, including allergic bronchopulmonary aspergillosis, eosinophilic granulomatosis with polyangiitis, bronchial tuberculosis and tracheal tumor.
