REVIEW
Estefania Fernandez, Michael S Diamond
The epidemic emergence of Zika virus (ZIKV) in 2015-2016 has been associated with congenital malformations and neurological sequela. Current efforts to develop a ZIKV vaccine build on technologies that successfully reduced infection or disease burden against closely related flaviviruses or other RNA viruses. Subunit-based (DNA plasmid and modified mRNA), viral vectored (adeno- and measles viruses) and inactivated viral vaccines are already advancing to clinical trials in humans after successful mouse and non-human primate studies...

PURPOSE OF REVIEW: This review aims to discuss the burden of type 2 diabetes in youth and summarize the studies that have utilized noninvasive techniques to assess early vascular disease in youth with type 2 diabetes. RECENT FINDINGS: Noninvasive imaging modalities provide researchers with tools to investigate the vasculature in adolescents with type 2 diabetes. The data published to date consistently show adolescents with type 2 diabetes have greater vascular thickness and stiffness and worse endothelial function compared to their obese and lean peers...

Alzheimer's disease (AD) is the most common form of dementia and is characterized by the cerebral accumulation of extracellular amyloid plaques. In a previous study, this histopathological hallmark was used as a target on a dual-functional nanoparticle (TQNP) to deliver biotechnological drugs, such as the H102 peptide, a β-sheet breaker, to AD lesions precisely. This delivery system could reduce the amyloid-β (Aβ) burden in the brains of AD model mice, as well as ameliorated the memory impairment of the mice...

The spatiotemporal pattern of cerebral amyloid deposition, detectable as light microscopically recognizable aggregates in an 'amyloid only' transgenic mouse model of Alzheimer's disease, B6C3-Tg(APPswe,PSEN1dE9)85Dbo/Mmjax, is reported for the first time in this strain. Monoclonal and polyclonal antibodies were used to detect amyloid deposition immunohistochemically in brains collected from these mice at 3-12 months of age. Amyloid aggregates (20-200 μm) were first found in serial, whole coronal sections of brain at 4 months of age and these increased progressively, plateauing at 11-12 months...

BACKGROUND: In studies of recurrent events, it is common to consider a person who has suffered a disease episode and received curative treatment to be not at risk of suffering a new episode for a duration of time. It is a common practice to deduct this duration from the person's observation time in the statistical analysis of the incidence data. METHODS: We examined the concepts of incidence and protective efficacy from a real life point of view. We developed simple formulae to show the relationship between the incidence rate and protective efficacy between analyses with and without deducting the curative treatment time from the observation time...

More than 3 million population residing in the holy city Varanasi and sub-urban areas is exposed to very high level of fine particulate matter (PM2.5) from various sources. Continuous monitoring by Central Pollution Control Board started only in 2015; therefore what was the pollution level in the past and how it has changed over the years are not known. We use MODIS aerosol products to infer PM2.5 and examine 15-year climatology. Data shows a rapid (1.5-3% per year) increase in PM2.5 in the last 15 years and high (87% days in a year) persistence of PM2...

Although cardiovascular disease is a major health burden for patients with chronic kidney disease, most cardiovascular outcome trials have excluded patients with advanced chronic kidney disease. Moreover, the major cardiovascular outcome trials that have been conducted in patients with end-stage renal disease have not demonstrated a treatment benefit. Thus, clinicians have limited evidence to guide the management of cardiovascular disease in patients with chronic kidney disease, particularly those on dialysis...

Aims: Paroxysmal atrial fibrillation (PAF) is often asymptomatic but nonetheless harmful. We evaluated the performance of disease-related blood biomarkers and CHA2DS2-VASc score to discriminate for PAF in patients with continuous rhythm monitoring. Methods and Results: Clinical data and blood samples were obtained from patients with dual-chamber pacemakers selected according to the absence (no_AHRE) or presence of Atrial High-Rate Episodes (AHRE) >6 min in recent device history (case-control approach)...

Signalling through the PERK/eIF2α-P branch of the unfolded protein response plays a critical role in controlling protein synthesis rates in cells. This pathway is overactivated in brains of patients with Alzheimer's disease and related disorders and has recently emerged as a promising therapeutic target for these currently untreatable conditions. Thus, in mouse models of neurodegenerative disease, prolonged overactivation of PERK/eIF2α-P signalling causes sustained attenuation of protein synthesis, leading to memory impairment and neuronal loss...

Amyotrophic lateral sclerosis is a progressive neurodegenerative disease of motor neurons. About 25 genes have been verified as relevant to the disease process, with rare and common variation implicated. We used next generation sequencing and repeat sizing to comprehensively assay genetic variation in a panel of known amyotrophic lateral sclerosis genes in 1126 patient samples and 613 controls. About 10% of patients were predicted to carry a pathological expansion of the C9orf72 gene. We found an increased burden of rare variants in patients within the untranslated regions of known disease-causing genes, driven by SOD1, TARDBP, FUS, VCP, OPTN and UBQLN2...

Epidemiological studies have reported associations between traditional cardiovascular risk factors and carotid intima-media thickness (CIMT) or carotid plaque. However, definite risk factors at different phases of carotid atherosclerosis remain controversial. We aimed to explore risk factors and characteristics of carotid atherosclerosis at different stages in a low-income population with a high incidence of stroke in China. Between April 2014 and January 2015, we recruited 3789 stroke-free and cardiovascular disease-free residents aged ≥ 45 years...

Recent findings from animal models suggest that plasticity of human circadian clocks and systems may be differentially affected by different paradigms of perinatal photoperiod exposure to the detriment of health in later life, including cancer development. Focusing on the example of cancer, we carry out a series of systematic literature reviews concerning perinatal light imprinting of circadian clocks and systems (PLICCS) in animal models, and concerning the risk of cancer development with the primary determinants of the perinatal photoperiod, namely season of birth or latitude of birth...

Integrated care tops the health care agenda. But more integration alone will not remedy the crisis in health care, and there is a danger in the increasingly prevalent conceptualization of care integration as a goal in itself rather than as an instrument for improving performance. Operating integrated care systems, staffed by an overly specialized medical workforce, is unsustainable in terms of human and financial resources and is likely to produce little benefit for patients with multi-morbidity. An alternative approach involves health care leaders going beyond integrated care and nurturing transformative change from within the medical workforce instead...

Rainbow trout Oncorhynchus mykiss surviving proliferative kidney disease (PKD) are reported not to develop the disease upon re-exposure. However, the mechanisms involved in the immune response to re-exposure are unknown. We examined disease susceptibility and the immune response of naive 1+ rainbow trout when first exposed to Tetracapsuloides bryosalmonae in comparison with that of 1+ rainbow trout re-exposed to T. bryosalmonae. PKD pathogenesis, parasite burden and transcriptional signatures of the host immune response were assessed at 10, 25 and 40 d...

OBJECTIVE: Familial hypercholesterolemia (FH) is a genetic disease characterized by extremely high levels of cholesterol, leading to premature atherosclerosis. Although many countries have already addressed the burden of FH by means of national registries, Turkey has no national FH registry or national screening program to detect FH. Creation of a series of FH registries is planned as part of Turkish FH Initiative endorsed by the Turkish Society of Cardiology to meet this need. This article provides detailed information on the rationale and design of the first 2 FH registries (A-HIT1 and A-HIT2)...
