OBJECTIVE: The absence of a gold standard for scleroderma renal crisis (SRC) has hindered our understanding of this problem. The objective of this scoping review was to identify the criteria used to define SRC in order to guide the development of a consensus definition for SRC. METHODS: We conducted a search in three databases: Medline, Embase and non-Ovid Pubmed. Papers were eligible for inclusion if they were full-length articles in English whose main topic was SRC or scleroderma renal disease...

H C Ringvold, R A Khalil
Vascular smooth muscle (VSM) plays an important role in maintaining vascular tone. In addition to Ca(2+)-dependent myosin light chain (MLC) phosphorylation, protein kinase C (PKC) is a major regulator of VSM function. PKC is a family of conventional Ca(2+)-dependent α, β, and γ, novel Ca(2+)-independent δ, ɛ, θ, and η, and atypical ξ, and ι/λ isoforms. Inactive PKC is mainly cytosolic, and upon activation it undergoes phosphorylation, maturation, and translocation to the surface membrane, the nucleus, endoplasmic reticulum, and other cell organelles; a process facilitated by scaffold proteins such as RACKs...

Metabolic syndrome and diabetes are main health problems of modern life in the twenty-first century. Alarming ratios of global prevalence lead to conduct more and more researches about etiological factors and pathogenesis. Disease mechanism is elementary for advancing more efficient and practicable treatment methods. Concurrent increase in both fructose consumption with Western diet and metabolic syndrome has revealed fructose hypothesis that suggests fructose as one of etiological factor of metabolic syndrome (insulin resistance, central obesity, hypertension, etc...

Pulmonary embolism (PE) is a frequent cause of death and serious disability with a risk extending far beyond the acute phase of the disease. Anticoagulant treatment reduces the risk for death and recurrent VTE after a first PE. The optimal duration of anticoagulation after a first episode of PE remains controversial and should be made on an individual basis, balancing the estimated risk for recurrence without anticoagulant treatment against bleeding risk under anticoagulation. Current recommendations on duration of anticoagulation are based on a 3% per year risk of major bleeding expected during long-term warfarin treatment...

Importance: Optical coherence tomographic angiography (OCT-A) is able to visualize retinal microvasculature without the need for injection of fluorescein contrast dye. Nevertheless, it is only able to capture a limited view of macula and does not show leakage. Objectives: To evaluate the retinal microvasculature using OCT-A in patients with type 2 diabetes as well as the association of OCT-A characteristics with diabetic retinopathy (DR) and systemic risk factors...

RATIONALE: Chronic obstructive pulmonary disease (COPD) is the third-leading cause of death in the United States. Emphysema on computed tomography (CT) is associated with increased morbidity and mortality in patients with and without spirometrically defined COPD but no available medications target emphysema.  Transforming growth factor beta (TGF-β) and endothelial dysfunction are implicated in emphysema pathogenesis, and angiotensin II receptor blockers (ARB) inhibit TGF-β, improve endothelial function and restore airspace architecture in murine models...

Pulmonary hypertension (PH) is a relatively commoner complication of systemic sclerosis (SSc) with estimated prevalence ranging between 8% and 12% as compared to much lower figures in other connective tissue diseases (CTD). It is a major cause of morbidity and mortality in CTDs. PH is classified into five major groups. CTD-associated PH belongs to group 1 PH, also known as pulmonary arterial hypertension (PAH). Around 30% of scleroderma-related deaths are due to PAH. Underlying pathogenesis is related to pulmonary vasculopathy involving small vessels...

Transient Receptor Potential Vanilloid 4 (TRPV4) is a broadly expressed, polymodally gated ion channel that plays an important role in many physiological and pathophysiological processes. TRPV4 knockout mice and several synthetic pharmacological compounds that selectively target TRPV4 are now available, which has allowed detailed investigation in to the therapeutic potential of this ion channel. Results from animal studies suggest that TRPV4 antagonism has therapeutic potential in oedema, pain, gastrointestinal disorders, and lung diseases such as cough, bronchoconstriction, pulmonary hypertension, and acute lung injury...

Portal hypertension (PH) is the main consequence of cirrhosis and is responsible for the majority of its complications. Gastroesophageal varices and variceal hemorrhage are direct consequences of PH; therefore, most clinical trials in PH have been directed toward treating or preventing variceal hemorrhage. However, varices and variceal hemorrhage are not isolated events; they must be considered in the context of the presence (or absence) of other complications of cirrhosis/PH. Cirrhosis progresses across different stages, each with a different prognosis and pathophysiology and hence different therapeutic targets...

Marcel Ruzicka, Swapnil Hiremath
PURPOSE OF REVIEW: Release of the findings from the Systolic Blood Pressure Intervention Trial has resulted in a renewed examination of intensive blood pressure (BP) lowering. Only a few national hypertension guidelines (Canada and Australia) have changed recommendations, but considerable heterogeneity still exists with respect to the patient population to whom intensive BP lowering may apply. RECENT FINDINGS: There is fairly robust evidence that lower BP targets in nondiabetic chronic kidney disease (CKD) results in a decrease in heart failure and mortality...

INTRODUCTION: Adiponectin is a pleiotropic adipocytokine with a strong inverse (protective) association with obesity, diabetes, and cardiovascular outcomes in stable patients. However, this relationship may be reversed in the setting of acute coronary syndrome (ACS). Given this possible complex relationship, we investigated adiponectin and cardiovascular (CV) outcomes in patients with diabetes and recent ACS. MATERIALS AND METHODS: We analyzed baseline adiponectin concentration and CV outcomes in 5,213 patients with type 2 diabetes enrolled 15-90 days (median 45 days) after ACS in the EXAMINE trial of alogliptin vs placebo...
