Pathophysiological, epidemiological, and genetic studies provide strong evidence that lipoprotein(a) [Lp(a)] is a causal mediator of cardiovascular disease (CVD) and calcific aortic valve disease (CAVD). Specific therapies to address Lp(a)-mediated CVD and CAVD are in clinical development. Due to knowledge gaps, the National Heart, Lung, and Blood Institute organized a working group that identified challenges in fully understanding the role of Lp(a) in CVD/CAVD. These included the lack of research funding, inadequate experimental models, lack of globally standardized Lp(a) assays, and inadequate understanding of the mechanisms underlying current drug therapies on Lp(a) levels...

There is an ongoing need for additional interventions in idiopathic pulmonary fibrosis (IPF) as antifibrotic drugs currently available only inhibit and do not stall disease progression. Vitamin K is a co-factor for the activation of coagulation factors. However, it is also required to activate proteins with functions outside of the coagulation cascade, such as matrix Gla protein (MGP), a defender against soft tissue calcification. Vitamin K antagonists are anticoagulants that are, for unknown reasons, associated with increased mortality in IPF...

Mitral annular calcification (MAC) is a common condition of the mitral valve apparatus. A case involving caseous calcification, a rare variant of MAC is presented. This variant which has a benign course can present as an intracardiac mass and needs to be differentiated from more sinister causes of calcified cardiac masses such as tumor, abscess, and infective vegetation. Often, this requires multimodality imaging with echocardiography, computed tomography, and magnetic resonance imaging. Features of caseous calcification of the mitral valve on these imaging modalities are reviewed as the associations and clinical features...

BACKGROUND: The outcome of extracorporeal membrane oxygenation (ECMO) might be influenced by its complications. Only limited information is available regarding the pathologic consequences of ECMO especially in the era of modern ECMO technology. METHODS: We studied the histopathologic findings in autopsy lungs of patients treated with ECMO as compared to those without ECMO. Autopsy files were queried for cases with ECMO. An age and gender-matched control group, comprised of patients who died in the Intensive Care Unit without acute respiratory distress syndrome, pneumonia, or ECMO, was compared with patients with ECMO for cardiac reason...

Chronic Mucocutaneous Candidiasis (CMC) is the chronic, recurrent, noninvasive Candida infections of the skin, mucous membranes, and nails. A 26-month-old girl was admitted with the complaints of recurrent oral Candidiasis, diarrhea, and respiratory infections. Candida albicans grew in oral mucosa swab. CMV and EBV DNA titers were elevated. She had hypergammaglobulinemia; IgE level, percentages of lymphocyte subgroups, and in vitro T-cell proliferation responses were normal. She had parenchymal nodules within the lungs and a calcific nodule in the liver...

We report a case of a persistent right upper lobe opacity following treatment for a Pseudomonas infection in an immunosuppressed patient with a recent renal transplantation. The patient underwent a surgical lung biopsy for definitive diagnosis of the mass. The lesion was composed of extensive calcifications deposited throughout the lung with associated fibrosis. The patient had a history of a remote parathyroidectomy for hyperparathyroidism; however, the parathyroid hormone (PTH) and the calcium levels were still mildly elevated...

AIMS: Organizing pneumonia (OP) is composed of loose granulation tissue plugs in distal airspaces; these disappear with steroid treatment. Recently a variant labeled "cicatricial" OP has been described in which the granulation tissue organized to much denser fibrous tissue but still retained the usual pattern of OP. Here we report 10 patients thought to have an interstitial lung disease, and who on biopsy had a variant of cicatricial OP characterized by linear bands or small nodular masses of dense fibrous tissue that does not resemble ordinary OP...

Subsequent to the widespread use of multidetector computed tomography and growing interest in lung cancer screening, small pulmonary nodules are more frequently detected. The differential diagnosis for a solitary pulmonary nodule is extremely broad and includes both benign and malignant causes. Recognition of early lung cancers is vital, since stage at diagnosis is crucial for prognosis. Estimation of the probability of malignancy is a challenging task, but crucial for follow-up and further work-up. In addition to the clinical setting and metabolic assessment, morphological assessment on thin-section computed tomography is essential...

BACKGROUND: Homozygous K108E mutation of interferon regulatory factor 8 (IRF8) is reported to cause dendritic cell and monocyte deficiency. However, more widespread immune dysfunction is predicted from the multiple roles ascribed to IRF8 in immune cell development and function. OBJECTIVE: We sought to describe the effect on hematopoiesis and immunity of compound heterozygous R83C/ R291Q mutation of IRF8, present in a patient with recurrent viral infection, granulo-proliferation and intracerebral calcification...

Video-assisted thoracoscopic surgery (VATS) lobectomy has been employed in recent decades for the treatment of non-small cell lung cancer (NSCLC). Although trials have shown this procedure to be safe and feasible a VATS approach for lobectomy has not been widely used yet. Surgeons can go beyond this limit by following a specific operative plan focused on learning the minimally invasive technique in centers of excellence and then including: a pre-operative phase based on the radioclinical assessments and an operating phase designed to develop a methodical approach to VATS technique...

Lung cancer is the most common cancer that cannot be ignored and cause death with late health care. Currently, CT can be used to help doctors detect the lung cancer in the early stages. In many cases, the diagnosis of identifying the lung cancer depends on the experience of doctors, which may ignore some patients and cause some problems. Deep learning has been proved as a popular and powerful method in many medical imaging diagnosis areas. In this paper, three types of deep neural networks (e.g., CNN, DNN, and SAE) are designed for lung cancer calcification...

Elastin is a unique protein providing deformability and resilience to dynamic tissues, such as arteries and lungs. It is an absolute basic requirement for circulation and respiration. Elastin can be degraded by elastases and has a high calcium affinity. Elastin calcification and elastin degradation are two pathological processes that impair elastin's functioning. Furthermore, elastin degradation can be associated to elastin calcification. Matrix Gla Protein (MGP) is probably the most potent natural inhibitor of elastin calcification and requires vitamin K for its activation...

RATIONALE: Pulmonary hamartomas are the most common benign tumor of the lung. Two types of pathologically similar hamartomas exist based on their location. These tumors have a low incidence, are rarely reported and frequently misdiagnosed because of lack of familiarity and/or understanding concerning their imaging features. PATIENT CONCERNS: Seventeen patients received treatment between June 2007 and May 2013 and had complete medical records. All of them had different degrees of cough and expectoration...

Accelerated elastin degradation is an important pathogenic mechanism in chronic obstructive pulmonary disease (COPD) leading to irreversible lung function loss and cardiovascular comorbidities. The rate of elastin breakdown is a predictor of mortality in patients with COPD. Decelerating elastinolysis might be an attractive therapeutic target in this debilitating condition. Vascular calcification starts in the elastin network of the arterial wall and is enhanced in patients with COPD. Elastin calcification is accompanied by an upregulation of matrix metalloproteinase gene expression and consequently a shift in the elastase/anti-elastase balance towards degradation...
