Hypertriglyceridemia and Cardiovascular Diseases: Revisited.

Sun, 27 Mar 2016 13:03:02 +0100

Authors: Han SH, Nicholls SJ, Sakuma I, Zhao D, Koh KK Abstract Residual cardiovascular risk and failure of high density lipoprotein cholesterol raising treatment have refocused interest on targeting hypertriglyceridemia. Hypertriglyceridemia, triglyceride-rich lipoproteins, and remnant cholesterol have demonstrated to be important risk factors for cardiovascular disease; this has been demonstrated in experimental, genetic, and epidemiological studies. Fibrates can reduce cardiovascular event rates with or without statins. High dose omega-3 fatty acids continue to be evaluated and new specialized targeting treatment modulating triglyceride pathways, such as inhibition of apolipoprotein C-III and angiopoietin-like proteins, are being tested with regard to their effects on lipid prof...

Testosterone and Cardiovascular Disease.

Sun, 27 Mar 2016 13:00:02 +0100

Authors: Tambo A, Roshan MH, Pace NP Abstract Cardiovascular disease [CVD] is a leading cause of mortality accounting for a global incidence of over 31%. Atherosclerosis is the primary pathophysiology underpinning most types of CVD. Historically, modifiable and non-modifiable risk factors were suggested to precipitate CVD. Recently, epidemiological studies have identified emerging risk factors including hypotestosteronaemia, which have been associated with CVD. Previously considered in the realms of reproductive biology, testosterone is now believed to play a critical role in the cardiovascular system in health and disease. The actions of testosterone as they relate to the cardiac vasculature and its implication in cardiovascular pathology is reviewed. PMID: 27014372 [PubMed] ...



Often seen, rarely recognized: mast cell activation disease - a guide to diagnosis and therapeutic options.

Sun, 27 Mar 2016 10:13:01 +0100

Authors: Afrin LB, H Butterfield J, Raithel M, J Molderings G Abstract Mast cell (MC) disease has long been thought to be just the rare disease of mastocytosis (in various forms, principally cutaneous and systemic), with aberrant MC mediator release at symptomatic levels due to neoplastic MC proliferation. Recent discoveries now show a new view is in order, with mastocytosis capping a metaphorical iceberg now called "MC activation disease" (MCAD, i.e. disease principally manifesting inappropriate MC activation), with the bulk of the iceberg being the recently recognized "MC activation syndrome" (MCAS), featuring inappropriate MC activation to symptomatic levels with little to no inappropriate MC proliferation. Given increasing appreciation of a great menagerie of mutations in MC re...



PGE2-EP3 signaling pathway contributes to protective effects of misoprostol on cerebral injury in APP/PS1 mice.

Sun, 27 Mar 2016 05:28:02 +0100

Authors: Tian X, Ji C, Luo Y, Yang Y, Kuang S, Mai S, Ma J, Yang J Abstract Epidemiological studies indicate chronic use of non-steroidal anti-inflammatory drugs (NSAIDs), which inhibit the enzymatic activity of the inflammatory cyclooxygenases (COX), reduces the risk of developing Alzheimer's disease (AD) in normal aging populations. Considering multiple adverse side effects of NSAIDs, findings suggest that COX downstream prostaglandin signaling function in the pre-clinical development of AD. Our previous study found that misoprostol, a synthetic prostaglandin E2 (PGE2) receptor agonist, has neuroprotection against brain injury induced by chronic aluminum overload. Here, we investigated the neuroprotective effects and mechanisms of misoprostol on neurodegeneration in overexpressin...

The mesolimbic system and eating addiction: what sugar does and does not do

Sat, 26 Mar 2016 23:00:00 +0100

Publication date: June 2016 Source:Current Opinion in Behavioral Sciences, Volume 9 Author(s): Johannes W De Jong, Louk JMJ Vanderschuren, Roger AH Adan Obesity and obesity-related disorders are a major threat to public health. It has been suggested that food addiction is a valid clinical concept and that food addiction is a contributing factor to the obesity epidemic. Research involving restricted access ‘binge’ diets has shown that rodents will display sucrose-related behavior that is reminiscent of substance addiction, under certain conditions. A question that remains, however, is if food or certain components of food possess addictive qualities akin to drugs of abuse. The alternative is that ‘food addiction’ (or rather ‘eating addiction’) is not a substance use disorde...

A Model For Sea Lice (Lepeophtheirus salmonis) Dynamics In A Seasonally Changing Environment

Sat, 26 Mar 2016 23:00:00 +0100

Publication date: Available online 26 March 2016 Source:Epidemics Author(s): Matthew A. Rittenhouse, Crawford W. Revie, Amy Hurford Sea lice (Lepeophtheirus salmonis) are a significant source of monetary losses on salmon farms. Sea lice exhibit temperature-dependent development rates and salinity-dependent mortality, but to date no deterministic models have incorporated these seasonally varying factors. To understand how environmental variation and life history characteristics affect sea lice abundance, we derive a delay differential equation model and parameterize the model with environmental data from British Columbia and southern Newfoundland. We calculate the lifetime reproductive output for female sea lice maturing to adulthood at different times of the year and find differences ...



Information Content of Household-Stratified Epidemics

Sat, 26 Mar 2016 23:00:00 +0100

Publication date: Available online 26 March 2016 Source:Epidemics Author(s): T.M. Kinyanjui, L. Pellis, T. House Household structure is a key driver of many infectious diseases, as well as a natural target for interventions such as vaccination programs. Many theoretical and conceptual advances on household-stratified epidemic models are relatively recent, but have successfully managed to increase the applicability of such models to practical problems. To be of maximum realism and hence benefit, they require parameterisation from epidemiological data, and while household-stratified final size data has been the traditional source, increasingly time-series infection data from households are becoming available. This paper is concerned with the design of studies aimed at collecting time-se...



Epidemiology and Severity of Sports and Recreation Injuries Presenting to a Tertiary Adult Emergency Department.

Sat, 26 Mar 2016 22:28:02 +0100

CONCLUSIONS: The 7.6% admission rate is higher than previously reported, likely because the study institution is a tertiary referral center. ATV riding is associated with higher severity injuries that are more likely to require hospital admission. Most sports injuries that present to an emergency department, specifically isolated soft tissue injuries of the extremities, may be more efficiently treated in a non-emergent setting.

Notes from the Field: Injuries Associated with Bison Encounters - Yellowstone National Park, 2015.

Sat, 26 Mar 2016 14:09:02 +0100

Authors: Cherry C, Leong K, Wallen R, Buttke D Abstract Since 1980, bison have injured more pedestrian visitors to Yellowstone National Park (Yellowstone) than any other animal (1). After the occurrence of 33 bison-related injuries during 1983-1985 (range = 10-13/year), the park implemented successful outreach campaigns (1) to reduce the average number of injuries to 0.8/year (range = 0-2/year) during 2010-2014 (unpublished data, National Park Service, September 2015). During May-July 2015, five injuries associated with bison encounters occurred (Table). Case reports were reviewed to evaluate circumstances surrounding these injuries to inform prevention.

Photokeratitis Linked to Metal Halide Bulbs in Two Gymnasiums - Philadelphia, Pennsylvania, 2011 and 2013.

Sat, 26 Mar 2016 14:09:02 +0100

Authors: Finn LE, Gutowski J, Alles S, Mirowitz N, Johnson C, Osterhoudt KC, Patel A Abstract In December 2011 and December 2013, the Philadelphia Department of Public Health (PDPH) received separate reports of clusters of photokeratitis linked to gymnasium events. Photokeratitis, a painful eye condition resulting from unprotected exposure to ultraviolet radiation, has previously been linked to metal halide lamps with broken outer envelopes (1,2). To investigate the cause of these clusters and further characterize patients with photokeratitis, PDPH administered questionnaires to potentially exposed persons, established a case definition, and conducted environmental assessments of both gymnasiums. Because event attendee registration information was available, a cohort study was cond...



Tuberculosis Among Temporary Visa Holders Working in the Tourism Industry - United States, 2012-2014.

Sat, 26 Mar 2016 14:09:02 +0100

This report describes three foreign-born persons holding temporary visas who had infectious TB while working at tourist destinations in the United States during 2012-2014. Multiple factors, including dormitory-style housing, transient work patterns, and diagnostic delays might have contributed to increased opportunity for TB transmission. Clinicians in seasonally driven tourist destinations should be aware of the potential for imported TB disease in foreign-born seasonal workers and promptly report suspected cases to health officials.

Leveling of Tuberculosis Incidence - United States, 2013-2015.

Sat, 26 Mar 2016 14:09:02 +0100

Authors: Salinas JL, Mindra G, Haddad MB, Pratt R, Price SF, Langer AJ Abstract After 2 decades of progress toward tuberculosis (TB) elimination with annual decreases of ≥0.2 cases per 100,000 persons (1), TB incidence in the United States remained approximately 3.0 cases per 100,000 persons during 2013-2015. Preliminary data reported to the National Tuberculosis Surveillance System indicate that TB incidence among foreign-born persons in the United States (15.1 cases per 100,000) has remained approximately 13 times the incidence among U.S.-born persons (1.2 cases per 100,000). Resuming progress toward TB elimination in the United States will require intensification of efforts both in the United States and globally, including increasing U.S. efforts to detect and treat latent TB ...

Perinatal Backgrounds and NICU Bed Occupancy of Multiple-Birth Infants in Japan.

Sat, 26 Mar 2016 10:06:02 +0100

Authors: Koshida S, Ono T, Tsuji S, Murakami T, Takahashi K Abstract Multiple pregnancies (twin, triplet, and higher-order pregnancy) are associated with an increased risk of resultant preterm and low birth weight infants. The increase of multiple pregnancies for several decades in Japan has been an important consideration in bed allocation planning for neonatal intensive care unit (NICU). The guideline of the Japan Society of Obstetrics and Gynecology (JSOG) in 2008 recommended that embryo transfer be limited to one. The epidemiological data of Japanese regional multiple pregnancies before the JSOG recommendation are valuable in assessing the perinatal effects after this recommendation. The aim of this study was to investigate regional backgrounds of multiple pregnancies and neona...

The social impact of Parkinson's disease in Spain: Report by the Spanish Foundation for the Brain

Fri, 25 Mar 2016 23:00:00 +0100

Conclusions The incidence and prevalence rates of Parkinson's disease in Spain are similar to those in the rest of Europe. According to current population estimates, there are at least 300 000 patients with Parkinson's disease and one new case per 10 000 habitants per year in Spain. This has a major impact on the patient's quality of life and nearly doubles patient mortality. In addition, the disease generates sizeable costs for the country that may exceed 17 000€ per year per patient; costs will rise due to the ageing of the population and the new therapies employed. Healthcare professionals and administrators dedicate their efforts to providing quality care to patients. Despite the above, we still have a long way to go in order to provide quality, efficient, multidisciplinary, and univ...

Fri, 25 Mar 2016 23:00:00 +0100

Publication date: Available online 25 March 2016 Source:Journal of Molecular Graphics and Modelling Author(s): Shaher Bano Mirza, Ramin Ekhteiari Salmas, M.Qaiser Fatmi, Serdar Durdagi Dengue virus is a major issue of tropical and sub-tropical regions. Dengue virus has been the cause behind the major alarming epidemics in the history with mass causalities from the decades. Unavailability of on-shelf drugs for the prevention of further proliferation of virus inside the human body results in immense number of deaths each year. This issue necessitates the design of novel anti-dengue drug. The protease enzyme pathway is the critical target for drug design due to its significance in the replication, survival and other cellular activities of dengue virus. Therefore, approximately eighteen ...



The Link Between Migraine, Reversible Cerebral Vasoconstriction Syndrome and Cervical Artery Dissection.

Fri, 25 Mar 2016 23:00:00 +0100

Authors: Mawet J, Debette S, Bousser MG, Ducros A Abstract Headache is the common thread of migraine, reversible cerebral vasoconstriction syndrome (RCVS) and cervical artery dissection (CeAD), three medical conditions that otherwise appear to be very different. However, epidemiological, clinical and genetic data suggest that these conditions share common and complex features and are, at least partly, linked. The purpose of this manuscript is to review existing evidence for an association between migraine, RCVS and CeAD and discuss the potential underlying mechanisms.

Repurposing metformin for cancer treatment: current clinical studies.

Fri, 25 Mar 2016 17:33:04 +0100

Authors: Chae YK, Arya A, Malecek MK, Shin DS, Carneiro B, Chandra S, Kaplan J, Kalyan A, Altman JK, Platanias L, Giles F Abstract In recent years, several studies have presented evidence suggesting a potential role for metformin in anti-cancer therapy. Preclinical studies have demonstrated several anticancer molecular mechanisms of metformin including mTOR inhibition, cytotoxic effects, and immunomodulation. Epidemiologic data have demonstrated decreased cancer incidence and mortality in patients taking metformin. Several clinical trials, focused on evaluation of metformin as an anti-cancer agent are presently underway. Data published from a small number of completed trials has put forth intriguing results. Clinical trials in pre-surgical endometrial cancer patients exhibited a si...

New insights into HIV epidemic in South Africa: key findings from the National HIV Prevalence, Incidence and Behaviour Survey, 2012.

Fri, 25 Mar 2016 15:52:07 +0100

This article presents key findings from the 2012 HIV prevalence, incidence and behaviour survey conducted in South Africa and explores trends in the HIV epidemic. A representative household based survey collected behavioural and biomedical data among people of all ages. Chi-squared test for association and formal trend tests (2002, 2005, 2008 and 2012) were used to test for associations and trends in the HIV epidemic across the four surveys. In 2012 a total of 38 431 respondents were interviewed from 11 079 households; 28 997 (67.5%) of 42 950 eligible individuals provided blood specimens. HIV prevalence was 12.2% [95% CI: 11.4-13.1] in 2012 with prevalence higher among females 14.4% than males 9.9%. Adults aged 25-49 years were most affected, 25.2% [95% CI: 23.2-27.3].

Gender inequality dynamics in the prevention of a heterosexual HIV epidemic in sub-Saharan Africa.

Fri, 25 Mar 2016 15:52:07 +0100

Authors: Wathuta J Abstract This paper critiques the approach to the elimination of gender inequality as an HIV prevention strategy in the just ended era of the Millennium Development Goals, with the aim of contributing to the formulation of policy guidelines for sub-Saharan Africa in the Sustainable Development Goals. The aim is to underscore the mutual responsibility of women and men in achieving a sustainable HIV response and ending the epidemic. While taking into account the real vulnerability of women, prevention programmes can reflect gender dynamics more accurately so that attention is given to the role of both sexes in propagating - or stemming - a predominantly heterosexual HIV epidemic. More emphasis could be given to the harm caused to both men and women by certain norms...

The use of cash transfers for HIV prevention - are we there yet?

Fri, 25 Mar 2016 15:52:07 +0100

Authors: Taaffe J, Cheikh N, Wilson D Abstract Poverty and social inequality are significant drivers of the HIV epidemic and are risk factors for acquiring HIV. As such, many individuals worldwide are at risk for new HIV infection, especially young women in East and Southern Africa. By addressing these drivers, social protection programmes may mitigate the impact of poverty and social inequality on HIV risk. There is reason to believe that social protection can be used successfully for HIV prevention; social protection programmes, including cash transfers, have led to positive health outcomes and behaviour in other contexts, and they have been used successfully to promote education and increased income and employment opportunities. Furthermore, cash transfers have influenced sexual...

Work stress and cardiovascular disease: a life course perspective.

Fri, 25 Mar 2016 12:49:02 +0100

Authors: Li J, Loerbroks A, Bosma H, Peter Angerer A Abstract Individuals in employment experience stress at work, and numerous epidemiological studies have documented its negative health effects, particularly on cardiovascular disease (CVD). Although evidence on the various interrelationships between work stress and CVD has been accumulated, those observations have not yet been conceptualized in terms of a life course perspective. Using the chain of risk model, we would like to propose a theoretical model incorporating six steps: (1) work stress increases the risk of incident CVD in healthy workers. (2) Among those whose work ability is not fully and permanently damaged, work stress acts as a determinant of the process of return to work after CVD onset. (3) CVD patients experience...

Upper tract urothelial carcinoma: epidemiology, high risk populations, and detection.

Fri, 25 Mar 2016 12:35:02 +0100

Authors: Redrow GP, Matin SF Abstract Upper tract urothelial carcinoma (UTUC) is a rare but highly morbid genitourinary malignancy. In 2014 approximately 15000 new cases were diagnosed in the United States. It accounts for approximately 5-10% of all urothelial cell carcinomas, and 10% of renal tumors. Recent research has increased understanding of the epidemiology of this disease, including several high-risk populations. Environmental exposure to tobacco as well as aristolochic acid, and other carcinogens significantly increase the development of UTUC. Additionally, the genetic condition of hereditary nonpolyposis colorectal carcinoma (HNPCC), also known as Lynch Syndrome (LS) is linked to development of UTUC. Advances in imaging, ureteroscopy, cytological techniques and pathologic...

Decision-making in an era of cancer prevention via aspirin: New Zealand needs updated guidelines and risk calculators.

Fri, 25 Mar 2016 05:09:03 +0100

Authors: Wilson N, Selak V, Blakely T, Leung W, Clarke P, Jackson R Abstract Based on new systematic reviews of the evidence, the US Preventive Services Task Force has drafted updated guidelines on the use of low-dose aspirin for the primary prevention of both cardiovascular disease (CVD) and cancer. The Task Force generally recommends consideration of aspirin in adults aged 50-69 years with 10-year CVD risk of at least 10%, in who absolute health gain (reduction of CVD and cancer) is estimated to exceed absolute health loss (increase in bleeds). With the ongoing decline in CVD, current risk calculators for New Zealand are probably outdated, so it is difficult to be precise about what proportion of the population is in this risk category (roughly equivalent to 5-year CVD risk ≥5%...

Epidemiology of dengue in Nepal: History of incidence, current prevalence and strategies for future control.

Fri, 25 Mar 2016 01:45:02 +0100

Authors: Subedi D, Taylor-Robinson AW Abstract Dengue is now established as one of the most important arboviral infections. As the epidemic continues unabated globally, this Aedes mosquito-transmitted pathogen is considered a major re-emerging tropical disease and significant public health concern. Four well-established distinct serotypes of dengue virus, with a fifth one recently proposed, are responsible for causing a spectrum of clinical symptoms in humans ranging from mild fever to severe haemorrhagic manifestations. Indigenous cases of dengue were first recognised in Nepal, a Himalayan country bordered by India and China, just a decade ago in a cluster of tropical and subtropical areas. Subsequently, the range of infection has extended all over the country and now comprises no...

Role of myokines in the maintenance of whole-body metabolic homeostasis.

Thu, 24 Mar 2016 23:46:03 +0100

Authors: Kostrominova TY Abstract Obesity is reaching epidemic proportions in developed countries and is on the rise in developing countries. Obesity-related changes in lipid and glucose metabolism predispose to the development of metabolic syndrome and type 2 diabetes. Skeletal muscle constitutes about 40 percent of total body weight and is unique compared to other muscle types since it is one of the most important organs for insulin-dependent glucose metabolism in humans. Abnormalities in skeletal muscle lipid and glucose metabolism as well as abnormal accumulation of intramyocellular lipids could predispose for the development of type 2 diabetes. Skeletal muscle synthesizes and secretes factors with autocrine/paracrine/endocrine functions that can regulate skeletal muscle metabo...



Multidrug-Resistant Tuberculosis and Its Association with Adrenal Insufficiency: Assessment with the Low-Dose ACTH Stimulation Test.

Conclusions. In patients with MDR-TB, using the low-dose ACTH stimulation test, a low prevalence of mild adrenal insufficiency was observed. After antituberculosis treatment adrenal function was restored in all cases. Given the increasing and worrying epidemic of MDR-TB these findings have important clinical implications that may help clinicians and patients make better decisions when deciding to test for adrenocortical dysfunction or treat insufficient stimulated cortisol levels in the setting of MDR-TB.

[In Depth] Don't blame sports for Zika's spread

Thu, 24 Mar 2016 23:00:00 +0100

Since the Zika virus began racing through the Americas, scientists have been trying to figure out when and where it entered Brazil, where it was first detected in March 2015. Speculation has focused on the influx of fans for the World Cup in June and July 2014, or for a championship canoe race in September 2014. But a new genome analysis suggests the virus had likely been spreading there long before either event, having arrived sometime between May and December 2013. It could have arrived during the Confederations Cup soccer tournament in late June 2013, the authors say. That event brought the Tahitian national team to a stadium in Recife, near the epicenter of the Brazilian epidemic. But that was several months before cases of Zika were reported in Tahiti, and the authors think it's more ...

The number of persons with symptomatic knee osteoarthritis in the United States: Impact of race/ethnicity, age, sex, and obesity

Thu, 24 Mar 2016 23:00:00 +0100

Conclusion: Over half of all persons with symptomatic knee OA are younger than 65 years of age. As many of these younger persons will live for three decades or more, there is substantially more time for greater disability to occur and policymakers should anticipate healthcare utilization for knee OA to increase further in upcoming decades. These data emphasize the need for the deployment of innovative prevention and treatment strategies for knee OA, especially among younger persons. This article is protected by copyright.

Survey definitions of gout for epidemiological studies: Comparison with crystal identification as the gold standard

Thu, 24 Mar 2016 23:00:00 +0100

Conclusions: A simple definition of ‘self‐report of gout or urate‐lowering therapy use' has the best test performance characteristics of existing definitions that use routinely available data. A more complex combination of features is more sensitive, but still lacks good specificity. If more accurate case‐definition is required for a particular study, the 2015 ACR‐EULAR Gout Classification criteria should be considered. This article is protected by copyright. All rights reserved.

Ad19a E3/49K Trafficking and Proteolytic Processing [Microbiology]

Thu, 24 Mar 2016 23:00:00 +0100

The E3 transcription unit of human species C adenoviruses (Ads) encodes immunomodulatory proteins that mediate direct protection of infected cells. Recently, we described a novel immunomodulatory function for E3/49K, an E3 protein uniquely expressed by species D Ads. E3/49K of Ad19a/Ad64, a serotype that causes epidemic keratokonjunctivitis, is synthesized as a highly glycosylated type I transmembrane protein that is subsequently cleaved, resulting in secretion of its large ectodomain (sec49K). sec49K binds to CD45 on leukocytes, impairing activation and functions of natural killer cells and T cells.

Thu, 24 Mar 2016 23:00:00 +0100

Diversity, evolution, and epidemiology of HIV are directly relevant to HIV transmission and pathogenesis; hence, they play a key role in antiretroviral treatment and vaccine design. Global HIV whole-genome sequencing would provide a treasure chest of data to answer many questions still open in these fields. An article by Berg et al. in this issue of the Journal of Clinical Microbiology describes a universal strategy to amplify and sequence heterogeneous HIV whole genomes (M. G. Berg, J. Yamaguchi, E. Alessandri-Gradt, R. W. Tell, J.-C. Plantier, and C. A. Brennan, J Clin Microbiol 54:868–882, 2016, http://dx.doi.org/10.1128/JCM.02479-15). (Source: Journal of Clinical Microbiology)
