Idiopathic pulmonary fibrosis (IPF) is a severe, progressive fibrotic disease of the lung of unknown etiology that affects approximately 150,000 patients in the United States. It carries a median survival of two to three years, but clinical course can vary markedly from patient to patient. ⋯ An enormous body of work in recent years, spanning the bench to the bedside, has radically altered our understanding of the molecular mechanisms underlying IPF. Newer modalities, particularly those involving monoclonal antibodies targeted at specific pathways known to contribute to the fibrotic process, have generated a great deal of excitement in the field, and recent clinical trials on therapies such as pirfenidone and nintedanib herald a new era in targeted IPF therapies.

Brown adipose tissue (BAT) is a specialized organ responsible for thermogenesis, a process required for maintaining body temperature. BAT is regulated by the sympathetic nervous system (SNS), which activates lipolysis and mitochondrial uncoupling in brown adipocytes. ⋯ On the basis of this evidence, extensive research has been focused on BAT function, where new molecules, such as irisin and bone morphogenetic proteins, particularly BMP7 and BMP8B, as well as novel central factors and new regulatory mechanisms, such as orexins and the canonical ventomedial nucleus of the hypothalamus (VMH) AMP- activated protein kinase (AMPK)-SNS-BAT axis, have been discovered and emerged as potential drug targets to combat obesity. In this review we provide an overview of the complex central regulation of BAT and how different neuronal cell populations co-ordinately work to maintain energy homeostasis.

To evaluate the effect of body weight (BW) on safety and efficacy of direct oral anticoagulants (DOACs). ⋯ Results of our meta-analysis suggested that DOACs might be a safe and effective therapeutic option for the treatment of acute VTE even in the patients with extreme body weights. However, other studies with larger study populations are warranted to confirm our findings.

Idiopathic pulmonary fibrosis (IPF) is the most common and lethal form of idiopathic interstitial pneumonia. The disease, which occurs primarily in middle-aged and older adults, is thought to arise following an aberrant reparative response to alveolar epithelial cell injury characterized by secretion of excessive amounts of extracellular matrix components, resulting in scarring of the lung, architectural distortion, and irreversible loss of function. A complex interplay between environmental and host factors is thought to contribute to the development of the disease, although the cause of IPF remains elusive and its pathogenesis incompletely understood. ⋯ This massive effort of the medical and industry community has led to the identification of two compounds (pirfenidone and nintedanib) able to reduce functional decline and disease progression. These promising results notwithstanding, IPF remains a major cause of morbidity and mortality and a largely unmet medical need. A real cure for this devastating disease has yet to emerge and will likely consist of a combination of drugs targeting the plethora of pathways potentially involved in disease pathogenesis.

Randomized Controlled Trial
The effects of canrenone on inflammatory markers in patients with metabolic syndrome.
To evaluate the effects of canrenone compared to placebo on blood pressure control, some non-conventional biomarkers in cardiovascular stratification, and on metalloproteinases in patients affected by metabolic syndrome. ⋯ Canrenone seems to be effective in reducing blood pressure in patients with metabolic syndrome. Moreover, canrenone seems also to improve MPO, Lp(a), and metalloproteinases in these patients.
