Are E-Cigs Bad For Your Heart?

Scientists are still trying to determine the health effects of e-cigarettes, and until now, they have focused their attention on the addictive properties of nicotine and the potentially cancer-causing agents in the vapors the devices emit. But in a small new study published in the Journal of the American Heart Association, researchers document another growing health concern of e-cigs: that they may have negative effects on the heart. Scientists led by Dr. Holly Middlekauff, professor of medicine at University of California Los Angeles, and her colleagues found that devices that contain nicotine can boost adrenaline levels in the heart—essentially putting the heart under stress, which is a major risk factor for heart attack and stroke. Middlekauff studied 33 healthy people who were not current tobacco or e-cigarette smokers and asked them to come to the lab on three different days. At each visit, they smoked a different device: a placebo with no active ingredients, an e-cig with nicotine or an e-cig without nicotine. (While e-cigs do not burn tobacco, most do contain nicotine.) For years, doctors believed that nicotine, while addictive, was not the component in cigarettes that posed the biggest health risk. Instead, they thought the tar that was more concerning. By comparing nicotine and non-nicotine e-cigs, Middlekauff wanted to determine whether the same was true for nicotine and the heart.

Authors: Musio F Abstract INTRODUCTION: Anemia has and will continue to be a central theme in medicine particularly as clinicians are treating a burgeoning population of complex multi-organ system processes. As a result of multiple randomized controlled trials (RCTs), meta-analyses, and societal recommendations overly restrictive paradigms and under-administration of erythropoiesis stimulating agents (ESAs) have likely been followed by clinicians among all specialties. AREAS COVERED: A review of anemia in the context of chronic kidney disease, hematologic malignancies and cancer is presented with focus on the e...

Authors: Sabet Sarvestani F, Azarpira N Abstract Heart and cerebral infarctions, as two important ischemic diseases, lead to the death of tissues due to inadequate blood supply and high mortality worldwide. These statuses are started via blockage of vessels and depletion of oxygen and nutrients which affected these areas. After reperfusion and restoration of oxygen supply, more severe injury was mediated by multifaceted cascades of inflammation and oxidative stress. microRNAs (miRNAs) as the regulator of biological and pathological pathways can adjust these conditions by interaction with their targets. Also, miRNAs...

Authors: Matti B, Zargar-Shoshtari K Abstract Prostate cancer represents a significant health burden worldwide. The cancer incidence had substantially increased since the introduction of prostate specific antigen (PSA) in cancer screening. This had led to considerable debates among health professionals and epidemiologists, since PSA as a screening tool seemed to be far from perfect. In New Zealand, the controversy was quite prominent in the last three decades, with some advocating the benefits of screening, while others concerned regarding the risk of harms. With the absence of an organised screening programme and ...

CONCLUSION: This study found that childhood cancer survivors in New Zealand had a high prevalence of developmental dental abnormalities and it identified potential risk factors related to their cancer treatment. Inequitable access to oral rehabilitation for this patient group argues for a mechanism for consistent improved access to publicly funded dental care across district health boards in New Zealand.

CONCLUSION: The nurse practitioner workforce offers stability and flexibility in working across multiple clinical settings in primary healthcare. They provide the potential solution to the general practitioner workforce shortage by improving access to primary healthcare and reducing health inequalities. As authorised prescribers able to enrol patients, receive capitation payments and claim general medical services, it is timely to facilitate the expansion of the nurse practitioner workforce in New Zealand.

This article summarizes the rationale for, and development of CDK inhibitors in melanoma, with their evolution from pan-CDK inhibitors to highly specific agents, throughout clinical trials and finally their potential future use. EXPERT OPINION: Whilst CDK inhibitors have been practice changing in breast cancer management, their efficacy is yet to be proven in melanoma. Combination with BRAF/MEK inhibitors has been hindered by dose-limiting toxicities, but their role may yet to be found within the spectrum of biomarker-derived personalized melanoma management. The effect that CDK inhibitors can have as an adjunct to imm...
