Over the course of the last 2 decades, the concept of remote ischemic conditioning (RIC) has attracted considerable research interest, because RIC, in most of its embodiments offers an inexpensive way of protecting tissues against ischemic damage inflicted by a number of medical conditions or procedures. Acute kidney injury (AKI) is a common side effect in the context of various medical procedures, and RIC has been suggested as a means of reducing its incidence. Outcomes regarding kidney function have been reported in numerous studies that evaluated the effects of RIC in a variety of settings (eg, cardiac surgery, interventions requiring intravenous administration of contrast media)...

WHAT IS KNOWN AND OBJECTIVES: Rituximab is a chimeric monoclonal anti-CD20 antibody approved for the treatment of some lymphoid malignancies as well as for autoimmune diseases including rheumatoid arthritis (RA), idiopathic thrombocytopenic purpura (ITP) and vasculitis. Generally, rituximab is well tolerated; nevertheless, some patients develop adverse effects including infusion reactions. Albeit rare, these reactions may in some cases be life-threatening conditions. Rituximab cardiovascular side effects include more common effects such as hypertension, oedema and rare cases of arrhythmias and myocardial infarction...

Obstructive sleep apnoea (OSA) is associated with increased risk of cardiovascular and cerebrovascular disease, a consequence attributed in part to chronic intermittent hypoxia (IH) resulting from repetitive apnoeas during sleep. Although findings from experimental animal, and human, models have shown that IH is detrimental to vascular regulation, the severity of IH used in many of these animal studies (e.g. inspired fraction of oxygen (FI O2 ) = 2-3%; oxygen desaturation index (ODI) = 120 events h(-1) ) is considerably greater than that observed in the majority of patients with OSA...

Aims: Common mental disorders i.e. depressive and anxiety disorders (CMD) are frequent comorbid conditions in individuals with ischaemic heart disease (IHD). Still, their effect on preterm exit from the labour market [i.e. disability pension (DP)] in individuals with IHD has to date not been scrutinized. The aim of this study was to investigate the separate and joint effect of IHD and CMD on the risk of DP for women and men of working age. Material and methods: This population-based cohort study included all non-pensioned 4 823 069 individuals, registered as living in Sweden 31 December 2004 and then 16-64 years of age...

Patients with pressure ulcers are generally older, have a long hospital stay and often have a variety of comorbidities. The decision to perform surgery for pressure ulcer management can be difficult because of concerns about the risk of postoperative complications. The aim of this study was to analyse the relationship between comorbid conditions and surgical outcomes in order to guide patient selection for pressure ulcer surgery. In 57 patients, data on age, defect size, operating time, hospital stay, body mass index, surgical site, mobility state, cardiac ischaemic history, diabetes, renal failure, ventilator dependency, tracheostomy state, use of haemodilution therapy and cancer were evaluated using stepwise multiple logistic regression analysis to determine the relationships between variables...

BACKGROUND: People living with HIV-1 infection are at greater risk for cardiovascular disease than seronegative adults. Treatment of dyslipidaemia with statins has been challenging in people with HIV because of an increased potential for drug interactions due to competing cytochrome P450 metabolism between statins and commonly used antiretroviral agents. Neither pitavastatin nor pravastatin depend on cytochrome P450 for primary metabolism. We aimed to assess the safety and efficacy of pitavastatin versus pravastatin in adults with HIV and dyslipidaemia...

BACKGROUND: Few European studies investigating associations between short-term exposure to air pollution and incident stroke have considered stroke subtypes. Using information from the South London Stroke Register for 2005-2012, we investigated associations between daily concentrations of gaseous and particulate air pollutants and incident stroke subtypes in an ethnically diverse area of London, UK. METHODS: Modelled daily pollutant concentrations based on a combination of measurements and dispersion modelling were linked at postcode level to incident stroke events stratified by haemorrhagic and ischaemic subtypes...

Perinatal infection increases the vulnerability of the neonatal brain to hypoxic-ischaemic (HI) injury. Hypothermia treatment (HT) does not provide neuroprotection after pre-insult inflammatory sensitisation by lipopolysaccharide (LPS), a gram-negative bacterial wall constituent. However, early-onset sepsis in term babies is caused by gram-positive species in more than 90% of cases, and neuro-inflammatory responses triggered through the gram-negative route (Toll-like receptor 4, TLR-4) are different from those induced through the gram-positive route via TLR-2...

IPO (Ischaemic post-conditioning) is a promising method of alleviating myocardial IR (ischaemia -reperfusion) injury; however, IPO-mediated cardioprotection is lost in diabetic hearts via mechanisms that remain largely unclear. We hypothesized that decreased cardiac expression of DJ-1, a positive modulator of autophagy, compromises the effectiveness of IPO-induced cardioprotection in diabetic rats. Diabetic rats subjected to myocardial IR (30 min of coronary artery occlusion followed by 120 min of reperfusion) exhibited more severe myocardial injury, less cardiac autophagy, lower DJ-1 expression and AMPK (adenosine monophosphate-activated protein kinase)/mTOR (mammalian target of rapamycin) pathway activity than non-diabetic rats...

REVIEW

Community-acquired pneumonia (CAP) is a common condition; however, it appears to be overdiagnosed. Diagnosing CAP too frequently may be adding to the problems of overuse of antibiotics, such as bacterial resistance in the community and greater costs and complications in individuals. Data support that most patients with non-severe CAP can be treated for 3-5 days; however, most patients with CAP are receiving much longer courses of therapy. Macrolides such as azithromycin have the potential to prolong the QT interval, although large population studies show that this does not appear to result in excess cardiac mortality...

BACKGROUND: This study was designed to explore the beneficial effects of environmental enrichment (EE) on white matter glial changes in a mouse model of chronic cerebral hypoperfusion induced by bilateral common carotid artery stenosis (BCAS). METHODS: A total of 74 wild-type male C57BL/6J mice underwent BCAS or sham surgery. One week after surgery, the mice were randomly assigned into three different groups having varied amounts of EE-standard housing with no EE conditions (std), limited exposure with 3 h EE a day (3 h) and full-time exposure to EE (full) for 12 weeks...

BACKGROUND: The impact of cancer therapies on cardiac disease in the general adult cancer survivor population is largely unknown. Our objective was to evaluate which tyrosine kinase-targeting drugs are associated with greater risk for new-onset heart failure (HF). METHODS: A nested case-control analysis was conducted within a cohort of 27 992 patients of Clalit Health Services, newly treated with a tyrosine kinase-targeting, and/or chemotherapeutic drug, for a malignant disease, between 1 January 2005 and 31 December 2012...

BACKGROUND: Immunoglobulins(Igs)play an important role in host defence and were initially thought to be expressed solely by B cells. However, recent data suggest that Igs are also expressed in other lineages. Recently, Ig transcripts were detected in cardiomyocytes, but whether the functional Ig protein is expressed by cardiomyocytes has not been thoroughly elucidated. METHODS: Gene Expression Omnibus (GEO) microarray database analysis was used to analyse IgM heavy chain expression in the myocardium of mice...

BACKGROUND: Creatine phosphate (CrP) plays a fundamental physiological role by providing chemical energy for cell viability and activity, especially in muscle tissue. Numerous pathological conditions, caused by acute or chronic ischaemic situations, are related to its deficiency. For these reasons, it has been used as a cardioprotective agent in heart surgery and medical cardiology for many years. OBJECTIVE: This article gives a brief overview of the main characteristics of exogenous CrP...

OBJECTIVES: Approximately one in five stroke survivors suffer from difficulties with speech reception in noise, despite normal audiometry. These deficits are treatable with personal frequency-modulated systems (FMs). This study aimed to evaluate long-term benefits in speech reception in noise, after daily 10-week use of personal FMs, in non-aphasic patients with stroke with auditory processing deficits. DESIGN: This was a prospective non-randomised controlled trial study...

Thrombotic thrombocytopenic purpura (TTP; also known as Moschcowitz disease) is characterized by the concomitant occurrence of often severe thrombocytopenia, microangiopathic haemolytic anaemia and a variable degree of ischaemic organ damage, particularly affecting the brain, heart and kidneys. Acute TTP was almost universally fatal until the introduction of plasma therapy, which improved survival from <10% to 80-90%. However, patients who survive an acute episode are at high risk of relapse and of long-term morbidity...

BACKGROUND: Stromal derived factor-1α (SDF-1α/CXCL12) is a chemokine that is up-regulated in diseases characterised by tissue hypoxia, including myocardial infarction, ischaemic cardiomyopathy and remote ischaemic conditioning (RIC), a technique of cyclical, non-injurious ischaemia applied remote from the heart that protects the heat from lethal ischaemia-reperfusion injury. Accordingly, there is considerable interest in SDF-1α as a potential biomarker of such conditions. However, SDF-1α is rapidly degraded and inactivated by dipeptidyl peptidase 4 and other peptidases, and the kinetics of intact SDF-1α remain unknown...

Ischaemic brain injuries are rare conditions in the paediatric age group. Main causes include non-arteriosclerotic arteriopathies, which in childhood usually result from primary vasculitis of large or small vessels and lead to impaired perfusion and subsequent ischaemic brain lesions. In accordance with the nomenclature of systemic forms, CNS vasculitis is subdivided into groups, based on the size of affected vessels: angiography-positive primary angiitis of medium sized and large vessels (pPACNS), and angiography-negative angiitis of small vessels (svPACNS)...
