Vascular inflammation is a key component involved in the process of arthrosclerosis, which in turn increases the risk for cardiovascular injury. In the last 10 years, there have been many trials that looked at omega-3 fatty acids as a way to reduce cardiovascular risk. These trials observed the effects of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) on the traditional lipid panel and found that both EPA and DHA reduce triglyceride (TG) level and increase high-density lipoprotein cholesterol (HDL-C) levels but also increase the low-density lipoprotein cholesterol (LDL-C) levels. ⋯ The use of EPA as an adjunct therapy for high-risk patient has shown to help decrease cardiovascular risk. The reduction in risk is performed not only by decreasing TG but also by reducing vascular inflammation. Although because there are no randomized double-blind study looking at this, the research is inconclusive and requires further investigation.

Review Case Reports
Sertraline-Induced Rhabdomyolysis: A Case Report and Literature Review.
The objective of this study is to report a case of sertraline-induced rhabdomyolysis in a female patient with a history of depression. A 25-year-old Hispanic woman with a history of depression reported to the emergency department (ED) with a chief complaint of muscle swelling and soreness and dark urine. The patient's creatine phosphokinase was 15,103 U/L. ⋯ Unlike the majority of previous reports, our patient was not taking other medications with documented association to rhabdomyolysis and had performed routine exercise before presenting with rhabdomyolysis. Although the mechanism of SSRI-induced rhabdomyolysis is not known, a theory posits that sertraline may have a role in muscle contraction and relaxation, leading to shorter time to contracture and longer time of contraction. The use of sertraline and other SSRIs may be associated with development of rhabdomyolysis, especially in the presence of strenuous exercise.

Syncope is defined as a transient loss of consciousness due to cerebral hypoperfusion followed by spontaneous recovery. Common causes of syncope include vasovagal syncope, situational syncope, orthostatic hypotension, carotid sinus hypersensitivity, left- and right-sided obstructive cardiac lesions, and cardiac arrhythmias. History and physical examination often provide valuable clues about the underlying etiology of syncope. ⋯ Evaluation of a patient with syncope involves a large battery of diagnostic tests that include a 12-lead electrocardiogram, Holter monitoring, echocardiogram, tilt table testing, ischemia evaluation, electrophysiologic studies, and other imaging tests. Despite the availability of these advanced diagnostic tests, a significant proportion of patients with syncope remain undiagnosed. Therapy should be tailored based on the underlying etiology of syncope.

Review Case Reports
Sudden Cardiac Arrest in a Patient With Apical Hypertrophic Cardiomyopathy: Case Report and a Brief Review of Literature.
Apical hypertrophic cardiomyopathy (HCM) is a phenotypic variant of nonobstructive HCM, in which hypertrophy of the myocardium predominantly involves the left ventricular apex. It is common in Japanese and other Asian populations but is rare in the United States. Apical HCM has a relatively benign prognosis in terms of cardiovascular mortality; however, morbid events such as ventricular aneurysms, apical thrombi, diastolic dysfunction, atrial fibrillation, and myocardial infarction are not uncommon. ⋯ The patient underwent an implantable cardioverter defibrillator placement for secondary prevention and was subsequently discharged. In conclusion, apical HCM can rarely be associated with adverse cardiovascular events. The diagnosis may be missed on transthoracic 2-dimensional cardiac echocardiogram, and cardiac magnetic resonance imaging should be considered to exclude apical HCM in young patients who present after sudden cardiac arrest.

The aging eye appears to be at considerable risk from oxidative stress. A great deal of research indicates that dysfunctional mitochondria are the primary site of reactive oxygen species (ROS). More than 95% of O2 produced during normal metabolism is generated by the electron transport chain in the inner mitochondrial membrane. ⋯ As a result of the combination of weak metal chelating, OH and lipid peroxyl radicals scavenging, reducing activities to liberated fatty acid, and phospholipid hydroperoxides, carnosine and carcinine appear to be physiological antioxidants able to efficiently protect the lipid phase of biologic membranes and aqueous environments and act as the antiapoptotic natural drug compounds The authors developed and patented the new ophthalmic compositions, including N-acetylcarnosine, acting as a prodrug of naturally targeted to mitochondria L-carnosine endowed with pluripotent antioxidant activities combined with mitochondria-targeted rechargeable antioxidant (either MitoVit E, Mito Q, or SkQs) as a potent medicine to treat ocular diseases. Such specificity is explained by the fact that developed compositions might be used to effectively prevent ROS-induced oxidation of lipids and proteins in the inner mitochondrial membrane in vivo and outside mitochondria in the cellular and tissue structures of the lens and eye compartments. Mitochondrial targeting of compounds with universal types of antioxidant activity represents a promising approach for treating a number of ROS-related ocular diseases of the aging eye and can be implicated in the management of cataracts.
