Samantha E Heron, Shokrollah Elahi
Mucosal surfaces account for the vast majority of HIV transmission. In adults, HIV transmission occurs mainly by vaginal and rectal routes but rarely via oral route. By contrast, pediatric HIV infections could be as the result of oral route by breastfeeding. As such mucosal surfaces play a crucial role in HIV acquisition, and spread of the virus depends on its ability to cross a mucosal barrier. HIV selectively infects, depletes, and/or dysregulates multiple arms of the human immune system particularly at the mucosal sites and causes substantial irreversible damage to the mucosal barriers...

PURPOSE OF REVIEW: Cardiovascular disease (CVD) increasingly afflicts people living with HIV (PLWH) in the contemporary era of antiretroviral therapy (ART). Coronary artery disease (CAD) is the most widely studied cardiovascular problem in PLWH; however, less is known about other clinically relevant subtypes of CVD such as heart failure (HF), cerebrovascular disease, sudden cardiac death, pericardial diseases, and pulmonary hypertension. This paper reviews evidence of other subtypes of CVD as emerging issues in the post-ART era...

Hashrul Rashid, Ian T Meredith, Arthur Nasis
Cardiovascular disease remains the leading cause of morbidity and mortality in developed nations, with elevated low-density lipoprotein-cholesterol (LDL-C) levels being a major modifiable risk factor for coronary atherosclerosis. While lipid-lowering therapies such as statins are effective in lowering LDL-C, a proportion of patients do not achieve target LDL-C goals with statins or are intolerant to statins necessitating other treatment options. Proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors are a new class of agents that reduce LDL-C beyond the maximum achievable LDL-C reductions with statins, and have been well studied in different patient groups...

PURPOSE OF REVIEW: Introduction of combination antiretroviral therapy (ART) has increased the life expectancy of patients with HIV infection, allowing them to live longer with this chronic medical condition and consequently experiencing conditions such as cardiovascular diseases (CVDs). Several studies have investigated the increased risk of CVD in people living with HIV (PLWH). However, less is known about the exact mechanisms involved in this increased risk. Also, specific guidelines for management of CVD in PLWH have not been developed yet...

Despite the introduction of new drugs and innovative devices contributing in the last years to improve patients' quality of life, morbidity and mortality from cardiovascular diseases remain high. There is an urgent need for addressing the underlying problem of the loss of cardiac or vascular tissues and therefore developing new therapies. Autologous vascular transplants are often limited by poor quality of donor sites and heart organ transplantation by donor shortage. Vascular and cardiac tissue engineering, whose aim is to repair or replace cardiovascular tissues by the use of cells, engineering and materials, as well as biochemical and physicochemical factors, appears in this scenario as a promising tool to repair the damaged hearts and vessels...

The biology of sex differences deals with the study of the disparities between females and males and the related biological mechanisms. Gender medicine focuses on the impact of gender and sex on human physiology, pathophysiology and clinical features of diseases that are common to women and men. The term gender refers to a complex interrelation and integration of sex-as a biological and functional determinant-and psychological and cultural behaviours (due to ethnical, social or religious background). The attention to the impact of gender differences on the pathophysiology and, therefore, on the clinical management of the most common diseases, such as cardiovascular diseases (CVD), neurodegenerative disorders, immune and autoimmune diseases as well as several tumours, is in fact often neglected...

BACKGROUND: We sought to understand whether people living with HIV (PLHIV) ever on highly active antiretroviral therapy (ART) follow a pattern where morbidity is compressed into the last years of life or lessened as people age. We aimed to estimate health-adjusted life expectancy (HALE) among adults living with and without HIV, and examine dependency between causes of comorbidities. METHODS: The Comparative Outcomes and Service Utilization Trends (COAST) study is a retrospective cohort of adults (≥20 years) including all known PLHIV and a 10% random sample of the general population of British Columbia, and with longitudinal data spanning from April 1, 1996, to Dec 31, 2012...

PURPOSE OF REVIEW: In this review, we focus on the multiple advancements in the field of cardiovascular regenerative medicine and the state-of-the art of building a heart. An organ is comprised of cells, but cells alone do not comprise an organ. We summarize the components needed, the hurdles, and likely translational steps defining the opportunities for discovery. RECENT FINDINGS: The therapies being developed in regenerative medicine aim not only to repair, but also to regenerate or replace ailing tissues and organs...

Carotid artery stenosis is responsible for between 10-20% of all ischaemic strokes. Interventions, such as carotid endarterectomy and carotid stenting, effectively reduce the risk of stroke in selected individuals. This review describes the history of carotid interventions, and summarises reliable evidence on the safety and efficacy of these interventions gained from large randomised clinical trials.Early trials comparing carotid endarterectomy to medical therapy alone in symptomatic patients, and asymptomatic patients, demonstrated that endarterectomy halved the risk of stroke and perioperative death in these two unique populations...

BACKGROUND: Physical exercise mitigates fatigue during androgen deprivation therapy (ADT); however, the effects of different exercise prescriptions are unknown. OBJECTIVES: To determine the long-term effects of different exercise modes on fatigue in prostate cancer patients undergoing ADT. DESIGN, SETTING, AND PARTICIPANTS: Between 2009 and 2012, 163 prostate cancer patients aged 43-90 y on ADT were randomised to exercise targeting the musculoskeletal system (impact loading+resistance training; ILRT; n=58), the cardiovascular and muscular systems (aerobic+resistance training; ART; n=54), or to usual care/delayed exercise (DEL; n=51) for 12 mo across university-affiliated exercise clinics in Australia...

A high body mass index (BMI) and high waist circumference are important health risk factors predisposing for cardiovascular and metabolic diseases and certain cancers. Historically, underweight was a diagnostic criterion of HIV-infection. In a cross-sectional study the prevalence of BMI-categories and high waist circumference and its associated factors in patients visiting three outpatient HIV clinics in South Africa were measured with anthropometric measurements and structured questionnaires regarding socio-demographic information, quality of life (QoL), AIDS-related stigma, symptoms of depression, alcohol use, HIV related information and level of adherence to ART...

BACKGROUND: A consequence of the widespread uptake of anti-retroviral therapy (ART) is that the older South African population will experience an increase in life expectancy, increasing their risk for cardiometabolic diseases (CMD), and its risk factors. The long-term interactions between HIV infection, treatment, and CMD remain to be elucidated in the African population. The HAALSI cohort was established to investigate the impact of these interactions on CMD morbidity and mortality among middle-aged and older adults...

BACKGROUND: Recent studies have shown that early antiretroviral therapy (ART) initiation results in significant HIV transmission reduction. This is the rationale behind the "test and treat" policy of the World Health Organization (WHO). Implementation of this policy will lead to an increased incidence of ART-related adverse effects, especially in sub-Saharan Africa (SSA). Is the region yet ready to cope with such a challenging issue? MAIN BODY: The introduction and widespread use of ART have drastically changed the natural history of HIV/AIDS, but exposure to ART leads to serious medication-related adverse effects mainly explained by mitochondrial toxicities, and the situation will get worse in the near future...

With the advent and subsequent success of antiretroviral therapy, human immunodeficiency virus (HIV) infection has largely become a chronic condition and is increasingly seen alongside metabolic disorders such as dyslipidaemia and insulin resistance. Furthermore, the administration of antiretroviral therapy (ART) itself is associated with an increase in the incidence of metabolic risk factors (namely insulin resistance, lipoatrophy, dyslipidaemia, and abnormalities of fat distribution in HIV patients). Thus, further challenges in the management of HIV patients include the management of diabetes and the metabolic syndrome, non-alcoholic fatty liver disease (NAFLD)...

REVIEW
Martin R Cowie
Many patient with, or at risk of, cardiovascular disease have sleep disordered breathing (SDB), which can be either obstructive (with intermittent collapse of the upper airway) or central (episodic loss of respiratory drive). SDB is associated with sleep disturbance, hypoxemia, hemodynamic changes, and sympathetic activation. Such patients have a worse prognosis than those without SDB. Mask-based therapies of positive airway pressure targeted at SDB can improve measures of sleep quality and partially normalize the sleep and respiratory physiology, but recent randomized trials of cardiovascular outcomes in SDB have either been neutral (obstructive sleep apnea) or suggested the possibility of harm, likely from increased sudden death, in central sleep apnea...

Introduction Even if cardiovascular disease (CVD) drugs are supported by high level proofs, the results of CVD treatment present great disparities: there are still patients dying with supposed optimal treatment, patients facing adverse events and CVD remain the primary cause of death in the world. Pharmacogenomics is the basis of personalisation of the treatment able to allow higher medication success rates. In this review, we will present detailed examples of CVD drugs to highlight the complexity of this challenging field and we will discuss novel concepts that should be considered for a fastest integration of pharmacogenomics in clinical practice of CVD...

Cardiovascular disease is the leading cause of death worldwide. The heart is susceptible to pathologies that impact the myocardium directly, such myocardial infarction and consequent heart failure, as well as conditions with indirect cardiac effects, such cancer treatment-related cardiotoxicity. As the contractile cells of the heart, cardiomyocytes are essential for normal cardiac function. Various stress stimuli may result in transient damage or cell death in cardiomyocytes through apoptosis, necrosis or maladaptive autophagy...

BACKGROUND: There is growing evidence of an interaction between HIV-infection, anti-retroviral therapy (ART) and cardiovascular diseases (CVD). Epidemiological studies in Europe and North America have been observing a shift towards an increased incidence of coronary heart disease and acute myocardial infarctions in HIV-infected populations compared to the general population even after adjusting for traditional cardiovascular risk factors. Despite South Africa (and sub-Saharan Africa, SSA) being regarded as the epicentre of the global HIV epidemic, very little is known about the prevalence of cardiovascular risk factors and precursors of vascular disease in HIV-infected populations in this region...

There is a great need for engineered vascular grafts among patients with cardiovascular diseases who are in need of bypass therapy and lack autologous healthy blood vessels. In addition, because of the severe worldwide shortage of organ donors, there is an increasing need for engineered vascularized tissue constructs as an alternative to organ transplants. Additive manufacturing (AM) offers great advantages and flexibility of fabrication of cell-laden, multimaterial, and anatomically shaped vascular grafts and vascularized tissue constructs...
