The Zika prevention handbook : everything you need to know to stay safe
\"As the Zika virus continues to spread throughout North America, people need answers. What are the origins of this virus? How does it spread? Should we be concerned? How can we stop the spread of infected mosquitos? With the increasing prevalence of Zika, concrete answers are needed now more than ever - The Zika Prevention Handbook serves as the best reference for readers to stay informed about side-effects and symptoms, and to minimize your chance of contracting the virus. The Zika virus is a mosquito-borne infection that is estimated to have originated in Africa in the mid 1940's. In the last several years, the Zika virus has infected thousands of people around the world and has spread to over 60 countries. As of August 2016, Zika-infected mosquitoes have found a new home, the United States. The Zika virus has been reported in all 50 U.S. states, in addition to hundreds of reported cases throughout Mexico and Canada. With the assistance of infectious disease expert, Laura D. Kramer, PhD, author Alexander Webb has compiled the leading research from the U.S. Centers for Disease Control and Prevention (CDC). Whether you're an expectant mother worried about microcephaly (a side effect of Zika that causes babies to be born with abnormally small heads), planning a vacation to a tropical area, or living in an area where these contagious mosquitoes reside, this book is guaranteed to answer all your questions and ease your fears. Readers will learn about Zika's origins, transmission of the infection, leading prevention techniques, medical testing, symptoms and diagnosis, and much more.\" --Publisher's description.

Effect of the first federally funded US antismoking national media campaign
Every year, smoking kills more than 5 million people globally, including 440 000 people in the USA, where the long-term decline in smoking prevalence has slowed. The US Centers for Disease Control and Prevention (CDC) delivered a national, 3-month antismoking campaign called Tips From Former Smokers (Tips) that started in March, 2012, in which hard-hitting, emotionally evocative television advertising was featured, depicting smoking-related suffering in real people. We aimed to assess the effects of the Tips campaign.
We undertook baseline and follow-up surveys of nationally representative cohorts of adult smokers and non-smokers. The national effect of the Tips campaign was estimated by applying rates of change in the cohort before and after the campaign to US census data.
3051 smokers and 2220 non-smokers completed baseline and follow-up assessments. 2395 (78%) smokers and 1632 (74%) non-smokers recalled seeing at least one Tips advertisement on television during the 3-month campaign. Quit attempts among smokers rose from 31·1% (95% CI 30·3–31·9) at baseline to 34·8% (34·0–35·7) at follow-up, a 12% relative increase. The prevalence of abstinence at follow-up among smokers who made a quit attempt was 13·4% (95% CI 9·7–17·2). Nationally, an estimated 1·64 million additional smokers made a quit attempt, and 220 000 (95% CI 159 000–282 000) remained abstinent at follow-up. Recommendations by non-smokers to quit grew from 2·6% at baseline to 5·1% at follow-up, and the prevalence of people talking with friends and family about the dangers of smoking rose from 31·9% (95% CI 31·3–32·5) to 35·2% (34·6–35·9), resulting in an estimated 4·7 million additional non-smokers recommending cessation services and more than 6 million talking about the dangers of smoking.
The high-exposure Tips media campaign was effective at increasing population-level quit attempts. The growth in smokers who quit and became sustained quitters could have added from a third to almost half a million quality-adjusted life-years to the US population. Expanded implementation of similar campaigns globally could accelerate progress on the WHO Framework Convention on Tobacco Control and reduce smoking prevalence globally.

A lumped parameter modelling study of cerebral autoregulation in normal pressure hydrocephalus suggests the brain chooses to be ischemic
Normal pressure hydrocephalus (NPH) is associated with a reduction in cerebral blood flow and an ischemic metabolic state. Ischemia should exhaust the available autoregulation in an attempt to correct the metabolic imbalance. There is evidence of some retained autoregulation reserve in NPH. The aim of this study is to model the cerebral autoregulation in NPH to discover a solution to this apparent paradox. A lumped parameter model was developed utilizing the known limits of autoregulation in man. The model was tested by predicting the cerebral blood volume changes which would be brought about by changes in resistance. NPH and the post shunt state were then modeled using the known constraints provided from the literature. The model successfully predicted the cerebral blood volume changes brought about by altering the cerebral perfusion pressure to the limit of autoregulation. The model suggests that NPH is associated with a balanced increase in resistance within the arterial and venous outflow segments. The arterial resistance decreased after modelling shunt insertion. The model suggests that the cerebral blood flow is actively limited in NPH by arteriolar constriction. This may occur to minimize the rise in ICP by reducing the apparent CSF formation rate.

A History of Organized Labor in Panama and Central America
The impact of an organized labor movement in Central America and Panama is explored through a historical lens, illustrating how economically exploited countries campaigned for personal financial interests. Reviews \"… [Alexander] derives much material in this book from personal involvement with Serafino Romualdi, an Italian anti-fascist, who acted as an anticommunist agent for the American Federation of Labor throughout Latin America. Along with Jay Lovestone, a former socialist turned anticommunist, Romualdi worked closely with the US State Department and the AFL to destabilize liberal Latin American governments and support friendly labor movements.\" Choice

Plasma Protein Biomarkers for Depression and Schizophrenia by Multi Analyte Profiling of Case-Control Collections
Despite significant research efforts aimed at understanding the neurobiological underpinnings of psychiatric disorders, the diagnosis and the evaluation of treatment of these disorders are still based solely on relatively subjective assessment of symptoms. Therefore, biological markers which could improve the current classification of psychiatry disorders, and in perspective stratify patients on a biological basis into more homogeneous clinically distinct subgroups, are highly needed. In order to identify novel candidate biological markers for major depression and schizophrenia, we have applied a focused proteomic approach using plasma samples from a large case-control collection. Patients were diagnosed according to DSM criteria using structured interviews and a number of additional clinical variables and demographic information were assessed. Plasma samples from 245 depressed patients, 229 schizophrenic patients and 254 controls were submitted to multi analyte profiling allowing the evaluation of up to 79 proteins, including a series of cytokines, chemokines and neurotrophins previously suggested to be involved in the pathophysiology of depression and schizophrenia. Univariate data analysis showed more significant p-values than would be expected by chance and highlighted several proteins belonging to pathways or mechanisms previously suspected to be involved in the pathophysiology of major depression or schizophrenia, such as insulin and MMP-9 for depression, and BDNF, EGF and a number of chemokines for schizophrenia. Multivariate analysis was carried out to improve the differentiation of cases from controls and identify the most informative panel of markers. The results illustrate the potential of plasma biomarker profiling for psychiatric disorders, when conducted in large collections. The study highlighted a set of analytes as candidate biomarker signatures for depression and schizophrenia, warranting further investigation in independent collections.

Lessons learned from the fate of AstraZeneca's drug pipeline: a five-dimensional framework
Pangalos and colleagues discuss the results of a comprehensive longitudinal review of AstraZeneca's small-molecule drug projects from 2005 to 2010. They present a framework to guide research and development teams based on the five most important technical determinants of project success and pipeline quality: the right target, the right patient, the right tissue, the right safety and the right commercial potential. A sixth factor — the right culture — is also crucial in encouraging effective decision-making.
Maintaining research and development (R&D) productivity at a sustainable level is one of the main challenges currently facing the pharmaceutical industry. In this article, we discuss the results of a comprehensive longitudinal review of AstraZeneca's small-molecule drug projects from 2005 to 2010. The analysis allowed us to establish a framework based on the five most important technical determinants of project success and pipeline quality, which we describe as the five 'R's: the right target, the right patient, the right tissue, the right safety and the right commercial potential. A sixth factor — the right culture — is also crucial in encouraging effective decision-making based on these technical determinants. AstraZeneca is currently applying this framework to guide its R&D teams, and although it is too early to demonstrate whether this has improved the company's R&D productivity, we present our data and analysis here in the hope that it may assist the industry overall in addressing this key challenge.
