Addiction to cocaine and other psychostimulants represents a major public health crisis. The development and persistence of addictive behaviors comes from a complex interaction of genes and environment - the precise mechanisms of which remain elusive. In recent years a surge of evidence has suggested that the gut microbiome can have tremendous impact on behavioral via the microbiota-gut-brain axis. In this study we characterized the influence of the gut microbiota on cocaine-mediated behaviors. Groups of mice were treated with a prolonged course of non-absorbable antibiotics via the drinking water, which resulted in a substantial reduction of gut bacteria...

In addition to its role as metabolic substrate that can sustain neuronal function and viability, emerging evidence supports a role for l-lactate as an intercellular signaling molecule involved in synaptic plasticity. Clinical and basic research studies have shown that major depression and chronic stress are associated with alterations in structural and functional plasticity. These findings led us to investigate the role of l-lactate as a potential novel antidepressant. Here we show that peripheral administration of l-lactate produces antidepressant-like effects in different animal models of depression that respond to acute and chronic antidepressant treatment...

Population health decision makers must consider complex relationships between multiple concepts measured with differential accuracy from heterogeneous data sources. Population health information systems are currently limited in their ability to integrate data and present a coherent portrait of population health. Consequentially, these systems can provide only basic support for decision makers. The Population Health Record (PopHR) is a semantic web application that automates the integration and extraction of massive amounts of heterogeneous data from multiple distributed sources (e...

Background | Differences (polymorphisms) in genes encoding drug targets, drug transport proteins, or drug metabolizing enzymes may be responsible, among other factors, for the observed variation in patients' responses to medications. The field of pharmacogenetics aims to identify patients at higher genetically-determined risk of adverse effects or poor response to medication. This information would allow for modification of dosage or substitution with alternative therapy. However, there is a lack of awareness of pharmacogenetic clinical practise guidelines...

Macular corneal dystrophy (MCD) is characterized by multiple punctate gray-white opacities in the corneal stromal region, due to the accumulation of abnormally sulfated keratan sulfates. We attempted to develop an in vitro model of MCD by simulating the sulfation inhibition using sodium chlorate, a chemical inhibitor of 3'-phosphoadenosine-5'-phosphosulfate (PAPs). The SEM and micro-Raman spectroscopy results showed the hallmark feature of MCD. Further the gene expression studies elucidated the direct effect of sulfation inhibition on the WNT pathway, that in turn downregulated production of matrix metalloproteinases (MMPs), which causes abnormal matrix deposits leading to loss of transparency in vivo...

BACKGROUND: The New York City emergency department (ED) syndromic surveillance (SS) system provides near real-time data on the majority of ED visits. The utility of ED SS for injury surveillance has not been thoroughly evaluated. We created injury syndromes based on ED chief complaint information and evaluated their utility compared to administrative billing data. METHODS: Six injury syndromes were developed: traffic-related injuries to pedal cyclists, pedestrians, and motor vehicle occupants; fall-related injuries; firearm-related injuries; and assault-related stabbings...

Dental implant surgery has developed to a widely used procedure for dental rehabilitation and is a secure and predictable procedure. Local and systemic risk factors can result in higher failure rates. Diabetes mellitus is a chronic disease that goes in with hyperglycemia and causes multifarious side effects. Diabetes as a relative contraindication for implant surgery is controversially discussed. Because the number of patients suffering from diabetes increases, there are more diabetic patients demanding implant procedures...

INTRODUCTION: The Brazilian Public Health System offers free-of-charge drug treatment for ankylosing spondylitis (AS) to all Brazilian citizens. We report here the first population-based cohort study on patients with AS in Brazil. The aim of this study was to evaluate the costs of the tumour necrosis factor (anti-TNF) blockers and disease-modifying antirheumatic drugs (DMARDs) that were used in the treatments of patients with AS in Brazil between March 2010 and September 2013. METHODS: A retrospective cohort study was performed using administrative databases...

Background: An increasing burden of chronic disease and associated health service delivery is expected due to the ageing Australian population. Injuries also affect health and wellbeing and have a long-term impact on health service utilisation. There is a lack of comprehensive data on disease and injury in rural and regional areas of Australia. The aim of the Ageing, Chronic Disease and Injury study is to compile data from various sources to better describe the patterns of chronic disease and injury across western Victoria...

Administration of chemotherapy often leads to gastrointestinal mucositis (GIM). GIM manifests as nausea, abdominal pain and diarrhoea in recipients of chemotherapy. GIM is a major complication occurring in approximately 80% of patients receiving 5-flurouracil treatment. These side-effects may become so severe that significant dose reductions are required, ultimately affecting treatment efficacy and patient survival. Complementary and alternative medicine (CAM) is a growing area of public interest. This review will provide an overview of current knowledge of complementary medicinal therapies for chemotherapy induced GIM...

BACKGROUND: Cocaine addiction continues to be a major heath concern, and despite public health intervention there is a lack of efficient pharmacological treatment options. A newly identified potential target are the group I metabotropic glutamate receptors (mGluR1/5), with allosteric modulators showing particular promise. METHODS: We evaluated the capacity of mGluR1/5 receptors to induce functional responses in ex vivo striatal slices from rats with 1) acute cocaine self-administration (CSA), 2) chronic CSA and 3) 60 days CSA withdrawal by westernblot and extracellular recordings of synaptic transmission...

Policy measures introduced in Spain during the economic crisis included a reduction in public health expenditure and in healthcare entitlements (RDL16/2012), which affected the general population as a whole, but especially immigrants. This paper analyzes changes in immigrants' access to health care during the economic crisis from the perspective of health professionals (medical and administrative) and immigrants. A qualitative descriptive-interpretative study was conducted in Catalonia through individual interviews with a theoretical sample of health professionals (n=34) and immigrant users (n=20)...

Over the past years, there has been a growing interest in the natural constituents of foods as a potential means of cancer control. To date, epidemiology studies seem to indicate an inverse association between regular consumption of fruit and vegetables and cancer risk. Here, the potential chemopreventive activity of the polyphenolic extract (PPE) of peach (Prunus persica L. Batsch) and of the freeze-dried fruit in toto (LFT), focusing on the modulation of xenobiotic metabolizing enzymes (XMEs) in vivo, was investigated...

Malaria, an infectious disease that kills more than 438,000 people per year worldwide, is a major public health problem. The emergence of strains resistant to conventional therapeutic agents necessitates the discovery of new drugs. We previously demonstrated that various substances, including terpenes, have antimalarial activity in vitro and in vivo. Nerolidol is a sesquiterpene present as an essential oil in several plants that is used in scented products and has been approved by the US Food and Drug Administration as a food-flavouring agent...

Although stroke declined from the third to fifth most common cause of death in the United States, the annual incidence and overall prevalence continue to increase. Since the available US Food and Drug Administration-approved treatment options are time dependent, improving early stroke care may have more of a public health impact than any other phase of care. Timely and efficient stroke treatment should be a priority for emergency department and prehospital providers. This article discusses currently available and emerging treatment options in acute ischemic stroke focusing on the preservation of salvageable brain tissue, minimizing complications, and secondary prevention...
