In hypertension, an increased media-to-lumen ratio of small resistance arteries might play an important role in the increase of vascular resistance, and may also be an adaptive response to the increased hemodynamic load. The presence of morphological alteration in the microvasculature may be associated to an impaired tissue perfusion and/or to the development of target organ damage. Structural alterations in the microcirculation might represent a predictor of the onset of cardio-cerebrovascular events and hypertension complications...

Anthracycline cardiotoxicity remains a serious problem in paediatric and adult cancer survivors, and the advancement of cardio-oncology is a necessary step for an effective care of the patients that experience adverse cardiovascular effects. In this review, we discuss the multiple instruments used by clinicians that constitute the current strategies for primary and secondary prevention aiming at contrasting the onset of early and late doxorubicin-induced cardiotoxic events. The importance of early detection of cardiotoxicity and the following pharmacological therapy has been acknowledged with the emphasis put on impaired diastolic function, an increasingly recognized precocious sign of doxorubicin cardiotoxicity with an emerging scientific and clinical interest...

REVIEW
Katrin Schröder, Norbert Weissmann, Ralf P Brandes
NADPH oxidases of the Nox family are important enzymatic sources of reactive oxygen species (ROS) in the cardiovascular system. Of the 7 members of the Nox family, at least three depend for their activation on specific cytosolic proteins. These are p47phox and its homologue NoxO1 and p67phox and its homologue NoxA1. Also the Rho-GTPase Rac is important but as this protein has many additional functions, it will not be covered here. The Nox1 enzyme is preferentially activated by the combination of NoxO1 with NoxA1, whereas Nox2 gains highest activity with p47phox together with p67phox...

With the rapidly rising number of patients surviving cancer, often in the setting of new or pre-existing cardiovascular disease and risk factors, a need has arisen for a specialty within the realm of cardiovascular care that can evaluate and manage these patients along with our colleagues in oncology and hematology. By the same token, all health care providers involved in the care of cancer patients with heart disease must be fully aware of the impact of adverse cardiovascular effects on the survival of these patients...

Metformin is a widely used drug for the treatment of type 2 diabetes (T2D). Its blood glucose-lowering effects are initially due to inhibition of hepatic glucose production and increased peripheral glucose utilization. Metformin has also been shown to have several beneficial effects on cardiovascular risk factors and it is the only oral antihyperglycaemic agent thus far associated with decreased macrovascular complications in patients with diabetes. Adenosine Monophosphate Activated-Protein Kinase (AMPK) is a major cellular regulator of lipid and glucose metabolism...

BACKGROUND: In recent years, staging laparoscopy has gained acceptance as part of the assessment of resectability of upper gastrointestinal (UGI) malignancies. Not infrequently, we encounter tumours that are either locally advanced; requiring neoadjuvant therapy or occult peritoneal disease that requires palliation. In all these cases, the establishment of enteral feeding during staging laparoscopy is important for patients' nutrition. This review describes our technique of performing laparoscopic feeding jejunostomy and the clinical outcomes...

Lung ultrasonography is a well established, user-friendly and easy-to-use technique that can be used in the evaluation of several pathological conditions affecting the lung. Adding lung ultrasonography to traditional echocardiography provides an integrated cardiopulmonary ultrasound analysis. The simultaneous collection of information about the heart and the lungs can help physicians to investigate acute and chronic cardio-pulmonary conditions within a noninvasive, single-probe and all-in-one examination, not exposing the patient to the danger of ionizing radiation...

PURPOSE OF REVIEW: Despite a significant increase in the utilization of donors after circulatory death (DCD), the number of organs recovered and their function are largely inferior to those from donors after brain death. This review summarizes recent advances in in-situ normothermic regional perfusion of DCD organs prior to procurement. RECENT FINDINGS: The combination of warm and cold ischemia in DCD donation are detrimental to organ function. As a consequence, the acceptance criteria are far more restrictive and many organs are discarded...

In the 19th century, cardio-active steroid glycosides, shortly cardiac glycosides, were scientifically established as drugs against heart failure. Their in vivo, cellular, and molecular actions as well as their predominant target, Na(+)-K(+)-ATPase, have been comprehensively investigated in the 20th century and the discovery of endogenous cardiac glycosides has fostered this research field. In the last years, however, results from clinical trials and meta-analyses have questioned their therapeutic value due to efficacy and safety issues...

The canonical transient receptor potential channels (TRPCs) constitute a series of nonselective cation channels with variable degrees of Ca²⁺ selectivity. TRPCs consist of seven mammalian members, TRPC1, TRPC2, TRPC3, TRPC4, TRPC5, TRPC6, and TRPC7, which are further divided into four subtypes, TRPC1, TRPC2, TRPC4/5, and TRPC3/6/7. These channels take charge of various essential cell functions such as contraction, relaxation, proliferation, and dysfunction. This review, organized into seven main sections, will provide an overview of current knowledge about the underlying pathogenesis of TRPCs in cardio/cerebrovascular diseases, including hypertension, pulmonary arterial hypertension, cardiac hypertrophy, atherosclerosis, arrhythmia, and cerebrovascular ischemia reperfusion injury...

Cardiovascular safety has become a central component of contemporary drug development and therapeutic use since noncardiovascular drugs can exert cardiovascular harms. Appropriate preapproval investigations and monitoring during clinical practice are therefore advantageous. Areas covered: Integrated cardiovascular safety is a broad field of investigation. This review focuses on three areas of assessment specifically chosen to exemplify advances and challenges in this field: the cardiotoxicity of oncologic agents, off-target blood pressure (BP) increases to noncardiovascular drugs, and the cardiovascular safety of new antidiabetic drugs for type 2 diabetes (T2D)...

Charlotte M Larsen, Sharon L Mulvagh
Cardio-oncology is a rapidly growing field aimed at minimizing the effects of cardiovascular morbidity and mortality in cancer survivors. To meet this aim, patients are assessed at baseline to define their risk of cardiotoxicity and then followed closely during and after chemotherapy to assess for early signs or symptoms of cardiovascular disease. Cardiac imaging, and in particular transthoracic echocardiography, plays an essential role in the baseline assessment and serial follow-up of cardio-oncology patients...

REVIEW
Angeliki Persynaki, Spyridon Karras, Claude Pichard
Periodic fasting, under a religious aspect, has been adopted by humans for centuries as a crucial pathway of spiritual purification. Caloric restriction, with or without exclusion of certain types of food, is often a key component. Fasting varies significantly among different populations according to cultural habits and local climate conditions. Religious fasting in terms of patterns (continuous versus intermittent) and duration can vary from 1 to 200 d; thus, the positive and negative impact on health can be considerable...

This review summarizes our current understanding of nonalcoholic fatty liver disease (NAFLD), a multi-factorial systemic disease resulting from a complex interaction between a specific genetic background and multiple environmental/metabolic "hits". The role of gut microbiota, lipotoxicity, inflammation and their molecular pathways is reviewed in-depth. We also discuss the epidemiology and natural history of NAFLD by pinpointing the remarkably high prevalence of NAFLD worldwide and its inherent systemic complications: hepatic (steatohepatitis, advanced fibrosis and cirrhosis), cardio-metabolic (cardiovascular disease, cardiomyopathy, arrhythmias and type 2 diabetes) and neoplastic (primary liver cancers and extra-hepatic cancers)...

PURPOSE OF REVIEW: Previous research suggests that low-moderate alcohol consumption may have cardioprotective effects, while heavy or binge-pattern drinking is harmful. New evidence and research methodology may inform safe thresholds of alcohol use. This review examines recent evidence regarding alcohol's effect on cardiovascular disease, with a special consideration of pattern, drink type, and total quantity. RECENT FINDINGS: New epidemiologic research confirms the potential harmful cardiovascular effects of heavy episodic alcohol use and does not support the previous observation that low-moderate alcohol use protects against stroke...

REVIEW
Atsunori Kashiwagi, Hiroshi Maegawa
The specific Na+/glucose co-transporter 2 inhibitors (SGLT2 inhibitors) inhibit glucose reabsorption in proximal renal tubular cells, and both fasting and postprandial glucose significantly decrease due to urinary glucose loss. As a result, pancreatic β-cell function and peripheral insulin action significantly improve with relief from glucose toxicity. Furthermore, whole body energy metabolism changes to relative glucose deficiency and triggers increased lipolysis in fat cells, and fatty acid oxidation and then ketone body production in the liver during treatment with SGLT2 inhibitors...
