We conducted a large-scale surveillance study as a post-marketing commitment to investigate safety and effectiveness of alectinib in patients with ALK-positive non-small-cell lung cancer (NSCLC) in Japan. Patients receiving 300mg twice-daily alectinib (September 2014 to June 2015) were monitored until termination of alectinib or completion of 18 months of treatment at 519 Japanese study sites. The primary endpoint was the incidence of adverse drug reactions (ADRs), which are important identified risks for alectinib in Japanese patients...

The recent increase in cardiovascular and metabolic disease in the Navajo population residing close to the Grants Mining District (GMD) in New Mexico is suggested to be due to exposure to environmental contaminants, in particular uranium in respirable dusts. However, the chemistry of uranium-containing-dust dissolution in lung fluids and the role of mineralogy are poorly understood, as is their impact on toxic effects. The current study is focused on the dissolution of xcontaining-dust, collected from several sites near Jackpile and St...

Immunoglobulin G4-related sialadenitis (IgG4-RS) is a newly recognized immune-mediated disease and one of immunoglobulin G4-related diseases (IgG4-RD). Our multidisciplinary research group investigated the clinicopathological characteristics and diagnosis of IgG4-RS during the past 10 years. Clinically, it showed multiple bilateral enlargement of major salivary glands (including sublingual and accessory parotid glands) and lacrimal glands. The comorbid diseases of head and neck region including rhinosinusitis, allergic rhinitis, and lymphadenopathy were commonly seen, which could occur more early than enlargement of major salivary glands...

BACKGROUND The hallmark of bullous pemphigoid (BP) is widespread tense blisters arising on normal or erythematous skin, often with marked pruritus, the diagnosis of which is confirmed by direct immunofluorescence (DIF). BP is an autoimmune process that can be induced, though rarely, by medications. Drug-induced BP often has atypical clinical presentation, which requires a good understanding of other dermatological conditions with similar presentations, in particular, bullous subtype of erythema multiforme. End organ involvement warrants differentiating it from one of the severe cutaneous adverse reaction (SCAR) syndromes...

OBJECTIVE: Chest computed tomography (CT) imaging is being increasingly used for potential lung donor assessment. However, the efficacy of CT imaging in this setting remains unknown. We hypothesize that chest CT imaging independently affects the decision-making process in donor lung utilization. METHODS: We conducted a retrospective cohort study of all adult donation after brain death donors managed through our local organ procurement organization from June 2011 to November 2016...

SS is a chronic, autoimmune disease of unknown aetiology for which there is no known curative treatment. Although dryness of the eyes and mouth are the classically described features, patients often experience drying of other mucosal surfaces and systemic manifestations, including fatigue and arthralgia. There is an association with other autoimmune diseases, especially thyroid disease, coeliac disease and primary biliary cholangitis. Systemic features may affect up to 70% and include inflammatory arthritis, skin involvement, haematological abnormalities, neuropathies, interstitial lung disease and a 5-10% lifetime risk of B cell lymphoma...

Recent human genetic studies have suggested an intriguing link between ciliary signaling defects and altered DNA damage responses in nephronophthisis (NPH) and related ciliopathies. However, the molecular mechanism and the role of altered DNA damage response in kidney degeneration and fibrosis have remained elusive. We recently identified the kinase-regulated DNA damage response target Apoptosis Antagonizing Transcription Factor (AATF) as a master regulator of the p53 response. Here, we characterized the phenotype of mice with genetic deletion of Aatf in tubular epithelial cells...

INTRODUCTION AND AIMS: Calcific aortic valve disease (CAVD) is the most common heart valve disease in western countries. It has been reported that activation of the calcium-sensing receptor(CaSR) expressed by vascular smooth muscle cells prevents vascular calcification. However, to date, the CaSR's expression and function in cardiac valves have not been studied. The present study sought to evaluate the presence of the CaSR within human valvular interstitial cells (hVICs), assess the CaSR's functionality, and ascertain its involvement in hVIC calcification...

Pulmonary fibrosis refers to the development of diffuse parenchymal abnormalities in the lung that cause dyspnea, cough, hypoxemia, and impair gas exchange, ultimately leading to respiratory failure. Though pulmonary fibrosis can be caused by a variety of underlying etiologies, ranging from genetic defects to autoimmune diseases to environmental exposures, once fibrosis develops it is irreversible and most often progressive, such that fibrosis of the lung is one of the leading indications for lung transplantation...

Chemically modified mRNA is a novel, highly efficient, biocompatible modality for therapeutic protein expression that may overcome the challenges and safety concerns with current gene therapy strategies. We explored the efficiency of intradermally injected modified VEGF-A165 mRNA (VEGF-A mRNA) formulated in a biocompatible citrate/saline buffer to locally produce human VEGF-A165 protein. Rabbits (n=4) and minipigs (n=3) were implanted with subcutaneous microdialysis probes close to the injection sites and interstitial-fluid samples and skin biopsies were analysed for production of VEGF-A protein over time for up to 8 hours...

We report the case of a 60-year-old woman with right breast cancer. Approximately 18 years had passed since the treatment for left breast cancer without recurrence. She became aware of the right breast tumor with mild pain 5 months before she came to the hospital. The diagnosis was right-sided breast cancer, cT2N0M0, StageⅡA, ER(-), PgR(-), HER2(-). Neoadjuvant chemotherapy was chosen, and then combined treatment with epirubicin(EPI)and cyclophosphamide(CPA) was started. The breast tumor had become smaller, but she complained of shortness of breath during the third course of chemotherapy...

Research on atrial histology of humans without cardiovascular disease is scarce. Therefore, our aim was to study human atrial histology in subjects without cardiovascular disease. Histology of the right atrium, left atrium or atrial septum was studied in eight patients (one newborn infant and seven adults) who died of a non-cardiac cause and who were not known to suffer from any cardiovascular pathology. Staining with hematoxylin phloxine saffron or Masson's trichrome was performed to have a better identification of fibrosis and H&E for better identification of lymphocytes...

BACKGROUND: Up to 12% of patients with systemic sclerosis (SSc) have anti-neutrophil cytoplasmic antibodies (ANCA). However, the majority of these patients do not manifest ANCA-associated vasculitis (AAV) and the significance of ANCA in these patients is unclear. The aim of this study is to determine the prevalence of ANCA in a well-characterised SSc cohort and to examine the association between ANCA and SSc clinical characteristics, other autoantibodies, treatments and mortality. METHODS: Clinical data were obtained from 5 centres in the Australian Scleroderma Cohort Study (ASCS)...
