Obesity is a heritable trait that contributes to substantial global morbidity and mortality. Here, we summarize findings from the last decade of genetic and epigenetic research focused on unravelling the underpinnings of adiposity. More than 140 genetic regions are now known to influence adiposity traits. The genetics of general adiposity, as measured by body mass index, and that of abdominal obesity, as measured by waist to hip ratio, have distinct biological backgrounds. Expression of genes associated with general adiposity are enriched in the nervous system...

Cancer is a complex disease: its pathology cannot be properly understood in terms of independent players-genes, proteins, molecular pathways, or their simple combinations. This is similar to many-body physics of a condensed phase that many important properties are not determined by a single atom or molecule. The rapidly accumulating large 'omics' data also require a new mechanistic and global underpinning to organize for rationalizing cancer complexity. A unifying and quantitative theory was proposed by some of the present authors that cancer is a robust state formed by the endogenous molecular-cellular network, which is evolutionarily built for the developmental processes and physiological functions...

INTRODUCTION: Twitter has recently gained popularity in emergency medicine (EM). Opinion leaders on Twitter have significant influence on the conversation and content, yet little is known about these opinion leaders. We aimed to describe a methodology to identify the most influential emergency physicians (EP) on Twitter and present a current list. METHODS: We analyzed 2,234 English-language EPs on Twitter from a previously published list of Twitter accounts generated by a snowball sampling technique...

The emergence and widespread dissemination of multidrug-resistant organisms is considered one of the three most important public health threats for humankind in the 21st century and jeopardizes the practice of modern medicine. Failure to tackle this problem in a comprehensive fashion could result in a dire post-antibiotic era, impairing the future development of treatments against important diseases, such as cancer, and transplant medicine, among others. Here, we provide a global perspective of the problem and describe some of the most important antibiotic-resistant organisms affecting the health of our patients...

Despite decades of basic research, biliary diseases remain prevalent, highly morbid, and notoriously difficult to treat. We have, however, dramatically increased our understanding of biliary developmental biology, cholangiocyte pathophysiology, and the endogenous mechanisms of biliary regeneration and repair. All of this complex and rapidly evolving knowledge coincides with an explosion of new technological advances in the area of regenerative medicine. New breakthroughs such as induced pluripotent stem cells and organoid culture are increasingly being applied to the biliary system; it is only a matter of time until new regenerative therapeutics for the cholangiopathies are unveiled...

D K Menon, A Ercole
Traumatic brain injury (TBI) is a growing global problem, which is responsible for a substantial burden of disability and death, and which generates substantial healthcare costs. High-quality intensive care can save lives and improve the quality of outcome. TBI is extremely heterogeneous in terms of clinical presentation, pathophysiology, and outcome. Current approaches to the critical care management of TBI are not underpinned by high-quality evidence, and many of the current therapies in use have not shown benefit in randomized control trials...

Cardiac arrest-induced global cerebral ischemia is a main cause of neurological dysfunction in emergency medicine. Transplantation with bone marrow mesenchymal stem cells (MSCs) has been used in stroke models to repair the ischemic brain injury, but it is little studied in models with global cerebral ischemia. In the present study, a hypoxia precondition was used to improve the efficacy of MSC transplantation, given the low survival and migration rates and limited differentiation capacities of MSCs. We found that hypoxia can increase the expansion and migration of MSCs by activating the PI3K/AKT and hypoxia-inducible factor-1α/CXC chemokine receptor-4 pathways...

The global emergence of antibiotic resistance, especially in Gram-negative bacteria, is an urgent threat to public health. Discovery of novel classes of antibiotics with activity against these pathogens has been impeded by a fundamental lack of understanding of the molecular drivers underlying small molecule uptake. Although it is well-known that outer membrane porins represent the main route of entry for small, hydrophilic molecules across the Gram-negative cell envelope, the structure-permeation relationship for porin passage has yet to be defined...

REVIEW
A U Lokugamage, S D C Pathberiya
This review describes the emerging global debate on the role of human rights childbirth. It is also tailored to a UK perspective in view of the Montgomery v. Lanarkshire [2015] legal ruling and it implications to practice. We can never underestimate the power of humane care on health. The compassion and evidence based medicine agenda in healthcare is interconnected with human rights in healthcare, feeding into the principles of decision making and patient centred care. When this has not happened and there is been healthcare conflict, the power of storytelling serves to connect disparate parties to their common humanity...

"Public Trust in Expert Knowledge: Narrative, Ethics, and Engagement" examines the social, cultural, and ethical ramifications of changing public trust in the expert biomedical knowledge systems of emergent and complex global societies. This symposium was conceived as an interdisciplinary project, drawing on bioethics, the social sciences, and the medical humanities. We settled on public trust as a topic for our work together because its problematization cuts across our fields and substantive research interests...

PURPOSE: Ionizing radiation (IR) is a ubiquitous environmental stressor with genotoxic and epigenotoxic capabilities. Terrestrial IR, predominantly a low-linear energy transfer (LET) radiation, is being widely utilized in medicine, as well as in multiple industrial applications. Additionally, an interest in understanding the effects of high-LET irradiation is emerging due to the potential of exposure during space missions and the growing utilization of LET radiation in medicine. CONCLUSIONS: In this review, we summarize the current knowledge of the effects of IR on DNA methylation, a key epigenetic mechanism regulating the expression of genetic information...

Zika virus is an emerging mosquito-borne (Aedes genus) arbovirus of the Flaviviridae family. Following epidemics in Micronesia and French Polynesia during the past decade, more recent Zika virus infection outbreaks were first reported in South America as early as May 2013 and spread to now 50 countries throughout the Americas. Although no other flavivirus has previously been known to cause major fetal malformations following perinatal infection, reports of a causal link between Zika virus and microcephaly, brain and ocular malformations, and fetal loss emerged from hard-hit regions of Brazil by October 2015...

BACKGROUND: Influenza vaccine hesitancy is a significant threat to global efforts to reduce the burden of seasonal and pandemic influenza. Potential barriers of influenza vaccination need to be identified to inform interventions to raise awareness, influenza vaccine acceptance and uptake. OBJECTIVE: This review aims to (1) identify relevant studies and extract individual barriers of seasonal and pandemic influenza vaccination for risk groups and the general public; and (2) map knowledge gaps in understanding influenza vaccine hesitancy to derive directions for further research and inform interventions in this area...

Influenza virus (IFV) causes periodic global influenza pandemics, resulting in substantial socio-economic loss and burden on medical facilities. Yearly variation in the effectiveness of vaccines, slow responsiveness to vaccination in cases of pandemic IFV, and emerging resistance to available drugs highlight the need to develop additional small-molecular inhibitors that act on IFV proteins. One promising target is polymerase acidic (PA) endonuclease, which is a bridged dinuclear metalloenzyme that plays a crucial role in initiating IFV replication...

There is an exponential increase in dementia in old age at a global level because of increasing life expectancy. The prevalence of neurodegenerative diseases such as dementia and Alzheimer's disease (AD) will continue to rise steadily, and is expected to reach 42 million cases worldwide in 2020. Despite the advancement of medication, the management of these diseases remains largely ineffective. Therefore, it is vital to explore novel nature-based nutraceuticals to mitigate AD and other age-related neurodegenerative disorders...
