F Z Saddouk, R Ginnan, H A Singer
Ca(2+)-dependent signaling pathways are central regulators of differentiated vascular smooth muscle (VSM) contractile function. In addition, Ca(2+) signals regulate VSM gene transcription, proliferation, and migration of dedifferentiated or "synthetic" phenotype VSM cells. Synthetic phenotype VSM growth and hyperplasia are hallmarks of pervasive vascular diseases including hypertension, atherosclerosis, postangioplasty/in-stent restenosis, and vein graft failure. The serine/threonine protein kinase Ca(2+)/calmodulin-dependent protein kinase II (CaMKII) is a ubiquitous mediator of intracellular Ca(2+) signals...

BACKGROUND: Cardiovascular diseases are well-known late effects of childhood cancer and research on these late effects is a highly important emerging field. We conducted a systematic review with a meta-analysis to give an overview of the current evidence and the prevalence of late cardiovascular events. PROCEDURE: We included publications in which the study populations were children and adolescents who survived cancer. Outcome was defined as all cardiovascular clinical and subclinical endpoints or diagnoses appearing at least one year after cancer diagnosis...

OBJECTIVES: Anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) is accompanied by increased cardiovascular (CV) risk. Treatment of AAV patients includes the management of conventional CV risk factors, primarily hypertension and hypercholesterolemia, while lipoprotein(a) (LP(a)) is an emerging potential target. METHODS: We performed a multicenter, retrospective study in Germany. Patients were considered if they were between 18 and 90 years old and presented with AAV...

M Miller, C Groombridge, R Lyon
Following the return of spontaneous circulation after out-of-hospital cardiac arrest, neurological dysfunction, airway or ventilatory compromise can impede transport to early percutaneous coronary intervention, necessitating pre-hospital or emergency department anaesthesia to facilitate this procedure. There are no published reports of the ideal induction agents in these patients. We sought to describe haemodynamic changes associated with induction of anaesthesia using a midazolam (0.1 mg.kg(-1) ), fentanyl (2 μg...

A distinctive syndrome caused by hypermucoviscous Klebsiella pneumoniae (HMKP) including pyogenic liver abscess (PLA) is now becoming a globally emerging disease. In the present study, 22.8% (84/369) of K. pneumoniae clinical isolates associated with various types of invasive infections were identified as HMKP, with 45.2% associated with PLA. Multivariate regression analysis showed that male patients with 41-50 years, PLA, diabetes mellitus, and hypertension were independent risk factors for HMKP infections...

Posterior reversible encephalopathy syndrome (PRES) is suggested in patients with acute neurological symptoms in the appropriate clinical context, including acute hypertension, blood pressure fluctuations, renal failure, blood transfusion, immunosuppression, autoimmune disorders, and eclampsia. PRES is a clinical syndrome, and refers to a disorder with reversible subcortical vasogenic brain edema caused by endothelial dysfunction, predominantly involving the bilateral parieto-occipital regions. Although the clinical course and prognosis are favorable in most cases, intracranial hemorrhage and/or restricted diffusion similar to acute infarction could be seen in some lesions on brain magnetic resonance imaging (MRI)...

Chronic obstructive pulmonary disease (COPD) is independently associated with atrial fibrillation (AF). Decreased oxygenation, hypercapnia, pulmonary hypertension, diastolic dysfunction, oxidative stress, inflammation, changes in atrial size by altered respiratory physiology, increased arrhythmogenicity from nonpulmonary vein foci commonly located in the right atrium, and respiratory drugs have been implicated in the pathogenesis of AF in COPD. The understanding of the relationship between COPD and AF is of particular importance, as the presence of the arrhythmia has significant impact on mortality, especially in COPD exacerbations...

Intracerebral hemorrhage (ICH) is a potentially devastating neurologic injury representing 10-15% of stroke cases in the USA each year. Numerous risk factors, including age, hypertension, male gender, coagulopathy, genetic susceptibility, and ethnic descent, have been identified. Timely identification, workup, and management of this condition remain a challenge for clinicians as numerous factors can present obstacles to achieving good functional outcomes. Several large clinical trials have been conducted over the prior decade regarding medical and surgical interventions...

BACKGROUND: Adjunctive automated whole blood or red blood cell exchange (RBCEx) can rapidly decrease malarial hyperparasitemia. Several case reports and series suggest improvement in clinical symptomatology; however, recent Centers of Disease Control and Prevention (CDC) recommendations concluded that RBCEx has no efficacy as an adjunctive therapy. We present a case of mental status changes secondary to cerebral malaria treated with automated RBCEx resulting in rapid and dramatic neurologic improvement...

Hypertension, or high blood pressure, is a prevalent yet modifiable risk factor for cardiovascular disease. While there are many effective treatments available to combat hypertension, patients often require at least two to three medications to control blood pressure, although there are patients who are resistant to such therapies. This short review will briefly update on recent clinical advances and potential emerging therapies and is intended for a cross-disciplinary readership.

Non-valvular atrial fibrillation (NVAF) significantly contributes to the burden of stroke, particularly in elderly patients. The challenge of optimizing anticoagulation therapy is balancing efficacy and bleeding risk, especially as the same patients at high risk of stroke also tend to be at high risk of bleeding. Treating the elderly patient with NVAF presents special challenges because of their heightened risk for both stroke and bleeding. Despite clinical trial data and evidence-based guidelines, surveys indicate that physicians underuse anticoagulation in older patients for reasons that include overemphasis of bleeding risk, particularly with the increased risk of falling, at the cost of thromboembolic risk...

Methamphetamine abuse during pregnancy represents an emerging health care problem. The consequences are not only of relevance to the pregnant women, but also their unborn child. It is associated with an increased risk of preeclampsia and hypertension, fetal demise, preterm delivery, and intrauterine growth restriction. The deleterious effects of prenatal methamphetamine exposure on the developing fetal brain may lead to long-term neuro-developmental and behavioral problems.Given the current evidence, abuse of methamphetamine during pregnancy must be of utmost concern to health care professionals and to policy-makers...

Intracerebral hemorrhage (ICH) is the second most common subtype of stroke and a critical disease usually leading to severe disability or death. ICH is more common in Asians, advanced age, male sex, and low- and middle-income countries. The case fatality rate of ICH is high (40% at 1 month and 54% at 1 year), and only 12% to 39% of survivors can achieve long-term functional independence. Risk factors of ICH are hypertension, current smoking, excessive alcohol consumption, hypocholesterolemia, and drugs. Old age, male sex, Asian ethnicity, chronic kidney disease, cerebral amyloid angiopathy (CAA), and cerebral microbleeds (CMBs) increase the risk of ICH...

Personalized medicine (PM), included in P5 medicine (Personalized, Predictive, Preventive, Participative and Precision medicine) is an innovative approach to the patient, emerging from the need to tailor and to fit the profile of each individual. PM promises to dramatically impact also on forensic sciences and justice system in ways we are only beginning to understand. The application of omics (genomic, transcriptomics, epigenetics/imprintomics, proteomic and metabolomics) is ever more fundamental in the so called "molecular autopsy"...

Hypertension (HTN) is the most common modifiable risk factor for cardiovascular disease (CVD) morbidity and mortality worldwide. Lower- and middle-income countries (LMICs) are projected to bear the vast majority of this disease burden, but local and regional health care delivery systems in these countries are ill equipped to meet this need. Emergency care is receiving increased recognition as a crucial component of public and community health. The rapid evolution of emergency care in LMICs provides a unique opportunity to develop innovative strategies, incorporating existing strengths of emergency departments, to address this paradigm shift in the disease burden associated with HTN on a global scale...

BACKGROUND: Patient-centered medical home (PCMH) has gained prominence as a promising model to encourage improved primary care delivery. There is a paucity of studies that evaluate the impact of payment models in the PCMH. OBJECTIVES: We sought to examine whether coupling coordinated, team-based care transformation plan with a novel reimbursement model affects outcomes related to expenditures and utilization. RESEARCH DESIGN: Interrupted time-series model with a difference-in-differences approach to assess differences between intervention and control groups, across time periods attributable to PCMH transformation and/or payment change...
