Abstract
The current evidence regarding the prevalence of subclinical carotid atherosclerosis (SCA) for people living with HIV(PLWH) is inconsistent. In this study, we aimed to synthesize data on the prevalence and association of SCA patients with HIV infection. We searched PubMed, EMBASE, Web of Science, Medline, SinoMed, and CNKI from inception to March 2, 2020. The pooled proportion, odds ratio (OR) with 95% confidence intervals (CIs) were calculated. For inclusion, SCA was measured by carotid intima-media thickness (CIMT), with a B-mode ultrasound machine. Twenty-six studies consisting of 6590 participants were identified. The overall prevalence of SCA was 31.6% (95% CI 13.4-53.3; I2 = 99%; 4 studies) according to CIMT ≥ 0.78 mm criteria, and 32.3% (19.6-46.4; 97%; 10 studies) according to CIMT ≥ 0.90 mm criteria. SCA prevalence was higher in Europe, over 40 years old and male. What's more, PLWH have a higher likelihood of developing SCA comorbidity than HIV-negative controls (pooled OR 2.66, 95% CI 1.57-4.50, I2 = 74%; 9 studies), even after sensitivity analysis (pooled OR 2.58, 1.54-4.31, 73%). This study suggests a high prevalence and risk of SCA in the global population with HIV. As a result, subclinical carotid atherosclerosis deserves more attention from policymakers, HIV health-care providers, researchers, and stakeholders.

Abstract
Introduction We report a case of stroke in a crack smoker with occlusion of the middle cerebral artery and a large thrombus in the carotid artery. Case Presentation. A 34-year-old female presented with left upper arm weakness, associated with paresthesia with onset of symptoms more than 24 hours before. Angio-RM sequences showed an area of ischemia, with occlusion of the M2 segment of the middle cerebral artery. Carotid ultrasound showed a soft plaque with distal end floating. Anticoagulant treatment was started, and seriated ultrasound evaluations showed its gradual dissolution. Conclusions In atherothromboembolic stroke from carotid thrombosis, repeated ultrasound studies may be useful for either diagnosis and monitoring the efficacy of anticoagulant therapy.

Abstract
INTRODUCTION To determine the association between magnetic resonance imaging (MRI)-detected vulnerable Carotid Plaques and clinical presentation related to ipsilateral carotid artery territory. EVIDENCE ACQUISITION We searched three databases including Ovid MEDLINE, Ovid EMBASE, and Scopus from 2000 to 2018 for studies that evaluated vulnerable carotid plaques by MRI defined as intraplaque hemorrhage (IPH), lipid-rich necrotic core (LRNC), or thinning/rupture of the fibrous cap (TRFC). Data on study characteristics, clinical presentation, and MRI findings were extracted. Publication bias, methodologic quality, and study heterogeneity were assessed. Random-effects meta-analysis model was used to estimate incidence rate ratio (IRR) and 95% confidence intervals (CI) of MRI-detected vulnerable carotid plaque between symptomatic and asymptomatic arteries. EVIDENCE SYNTHESIS Of 2855 studies, 33 studies containing 6210 participants with 8401 assessed arteries were included. Overall, the risk of bias was moderate in 13, and low in 20 studies. The prevalence of MRI-positive IPH, TRFC, and LRNC were higher in symptomatic groups compared with the asymptomatic groups. In 11 studies that compared vulnerable carotid plaques between symptomatic and asymptomatic groups, symptomatic presentation was correlated with increased risk of IPH (IRR=1.57; 95% CI: 1.24-1.99), TRFC (IRR=2.26; 95% CI: 1.83 to 3.76), and LRNC (IRR=1.95; 95% CI: 1.28 to 2.97), respectively. CONCLUSIONS The presence of MRI-positive vulnerable carotid plaques including IPH, LRNC, and TRFC is positively associated with symptomatic clinical presentation. Therefore, carotid plaque MRI might be a useful risk stratification tool in determining the risk of ischemic stroke.

Abstract
In many, but not all studies, people living with HIV (PLWH) have an increased risk of coronary artery disease (CAD) events compared to the general population. This has generated considerable interest in the early, non-invasive detection of asymptomatic (subclinical) atherosclerosis in PLWH. Ultrasound studies assessing carotid artery intima-media thickness (CIMT) have tended to show a somewhat greater thickness in HIV+ compared to HIV-, likely due to an increased prevalence of cardiovascular (CV) risk factors in PLWH. Coronary artery calcification (CAC) determination by non-contrast computed tomography (CT) seems promising to predict CV events but is limited to the detection of calcified plaque. Coronary CT angiography (CCTA) detects calcified and non-calcified plaque and predicts CAD better than either CAC or CIMT. A normal CCTA predicts survival free of CV events over a very long time-span. Research imaging techniques, including black-blood magnetic resonance imaging of the vessel wall and 18F-fluorodeoxyglucose positron emission tomography for the assessment of arterial inflammation have provided insights into the prevalence of HIV-vasculopathy and associated risk factors, but their clinical applicability remains limited. Therefore, CCTA currently appears as the most promising cardiac imaging modality in PLWH for the evaluation of suspected CAD, particularly in patients <50 years, in whom most atherosclerotic coronary lesions are non-calcified.

Abstract
Cocaine, a powerful vasoconstrictor, induces immune responses including cytokine elevations. Chronic cocaine use is associated with functional brain impairments potentially mediated by vascular pathology. Although the Crack-Cocaine epidemic has declined, its vascular consequences are increasingly becoming evident among individuals with cocaine use disorder of that period, now aging. Paradoxically, during the period when prevention efforts could make a difference, this population receives psychosocial treatment at best. We review major postmortem and in vitro studies documenting cocaine-induced vascular toxicity. PubMed and Academic Search Complete were used with relevant terms. Findings consist of the major mechanisms of cocaine-induced vasoconstriction, endothelial dysfunction, and accelerated atherosclerosis, emphasizing acute, chronic, and secondary effects of cocaine. The etiology underlying cocaine's acute and chronic vascular effects is multifactorial, spanning hypertension, impaired homeostasis and platelet function, thrombosis, thromboembolism, and alterations in blood flow. Early detection of vascular disease in cocaine addiction by multimodality imaging is discussed. Treatment may be similar to indications in patients with traditional risk-factors, with few exceptions such as enhanced supportive care and use of benzodiazepines and phentolamine for sedation, and avoiding β-blockers. Given the vascular toxicity cocaine induces, further compounded by smoking and alcohol comorbidity, and interacting with aging of the crack generation, there is a public health imperative to identify pre-symptomatic markers of vascular impairments in cocaine addiction and employ preventive treatment to reduce silent disease progression.

Abstract
HIV infection, depression, and cocaine use are independently associated with increased inflammatory signal production. There is increasing evidence about the role of inflammation in depression. In HIV disease, cocaine use may increase disease progression as well as alter T cell functioning resulting in cytokine activation and thereby increasing susceptibility to depression. We examined the association between cocaine use and depression among 447 African American persons infected with HIV who were frequent cocaine users or non-users, enrolled in an observational study in Baltimore, Maryland, between August 2003 and December 2012. The overall prevalence of depression was 40.9 % (183 of 447) participants. Among persons who were depressed, the prevalence of cocaine use was 81.4 % (149 of 183), compared to 69.3 % among persons who were not depressed (183 of 264), P = 0.004. Cocaine use was associated with nearly twofold increased odds of depression, unadjusted odds ratio (OR) 1.94, (95 % CI 1.23, 3.06); P = 0.004, compared to never using cocaine, and OR 1.02, (95 % CI 1.10, 1.05); P = 0.04 in adjusted analysis. A dose-response relationship between increasing duration of cocaine use and depression was observed. Frequency and duration of cocaine use may be associated with depression. We speculate that depression among cocaine users with HIV may involve an inflammatory component that needs further examination.

Abstract
Excited Delirium Syndrome (ExDS) is a term traditionally used in forensic literature to describe the symptoms and signs seen in a subgroup of patients with delirium who die in an agitated state. Components of this syndrome are altered mental status, combativeness and/or aggressiveness, increased tolerance to significant pain, tachypnea, profuse sweating, severe agitation, elevated temperature, delirium, and noncompliance with law enforcement and medical personnel. The individual may display “superhuman” strength and wear clothing inappropriate for the environment. Patients with this presentation are almost guaranteed to cause difficulties for law enforcement officers and medical staff. This review is written in hopes of minimizing some of these difficulties by 1) increasing general awareness and specific knowledge about this condition, 2) explaining the neurochemical and neuroanatomical alterations that have been shown to cause those symptoms, and 3) by suggesting new lines of research that might identify easily measured biomarkers for the disease. If the disease mechanism can be deciphered, then it should be possible to devise effective strategies for treatment. It would also be of enormous value to the legal system. When defending a diagnosis before the court, physical evidence always trumps knowledge and experience. It would be far better to be able to present physical proof than to opine that the decedent's behavior was typical for the disease. In this aspect, ExDS is analogous to myocardial infarction: if a man dies suddenly, it is much easier to prove the cardiac origin of the event if an occlusive thrombus is found in a major coronary artery.
