It’s like a FitBit for your sweat, detecting your blood alcohol level.
Skyn is a wristband from breathalyser company BACtrack, and it detects alcohol using a fuel cell technology not unlike that used by your friendly roadside RBT.
The device is worn on the wrist and offers continuous, real-time, and non-invasive monitoring of your TAC (Transdermal Alcohol Content). Alcohol is detected and measured with transdermal monitoring, which tracks the ethanol molecules escaping through the skin.
TAC samples are then converted into a history of your BAC (Blood Alcohol Content) with BACtrack’s proprietary algorithm. BACtrack Skyn uses an electrochemical sensor and connects via Bluetooth to an app on your smartphone.
Since it can take up to 45 minutes for alcohol to be transmitted through the skin its accuracy for some applications (like replacing traditional breathalysers) is unreliable. But what it can reliably be used for is continuous monitoring.
You can relay data to your doctor, it can warn you if you’ve had too much to drink.
Basically, you can passively track alcohol consumption in real-time. There’s no need to take a breath alcohol test — your estimated BAC result is on their wrist, continuously. For instance, your phone could vibrate to notify you that you’re approaching 0.04 per cent BAC and remind you to slow down your drinking.
If you’re aiming for sobriety, a nominated contact could receive a notification when your BAC has gone above 0.00 per cent.
Based in San Francisco, BACtrack won the “Wearable Alcohol Biosensor Challenge” competition held by the National Institute on Alcohol Abuse and Alcoholism with the Skyn, which came with a $200,000 prize. The competition aimed to uncover wearable technologies that can be used comfortably by everyday people, and was judged on accuracy.
The Preamble of the Constitution of the World Health Organization reminds us that «Informed opinion and active cooperation on the part of the public are of the utmost importance in the improvement of the health of the people» (Grad, 2002). Nonetheless, nearly seven decades later, the conditions under which people can be informed and actively participate in their health management in a meaningful way are being globally challenged. Drawing from experience in a variety of areas that I will delve into in this article, I remain a believer that we can marshal the necessary forces to advance the communication of health issues and create a base for a health-literate population to make smart(er), healthier decisions that advance health and well-being.
Keywords: health communication, health literacy, Ebola, vaccines, innovation.
The ultimate goal of health communication is to advance an informed and empowered individual who can make smart choices for themselves, their families and communities whether it be in daily life, business and/or public policy. While the goal and practice may seem elusive, a simple fundamental tenet is that we need to advance our communication prowess to develop health literacy from individuals to the body politic. Ideally, an ethical, evidence-based communication approach can build upon historical challenges of how we address issues in science and health – from creationism to the heliocentric theory of the universe to nuclear physics to climate change. While Darwin, Galileo, Copernicus and others challenged the conventional wisdom and the «faith-based» approach of their time, countless others joined then and now in advancing science-based approaches to make the world a better place.

According to a Pew Research Center report released last month, Americans are engaged and connected like never before. Nearly 70 percent own a smartphone, and 45 percent have a tablet-like device. It’s clear that almost all of us interact with mobile devices on a daily basis. Wearable sensor technology as well as connected watches and other mobile monitors are becoming more commonplace. And these new devices have the potential to significantly impact health care delivery in the U.S. today.
Drinking diet (or sugar free) fizzy drinks during pregnancy makes women more likely to give birth to overweight children, according to research from the University of Manitoba in Canada.
The researchers found that mothers who drink sugar free, artificially sweetened beverages during pregnancy are twice as likely to have an overweight baby by the age of 12 months.
The findings suggest the possibility that children who are exposed to artificial sweeteners in the womb could develop a sweet tooth, leading them to eat foods higher in calories — but cautioned that this was not a biological study, and that they had merely observed a link.
Replacing saturated fat with polyunsaturated fat might not prolong life
It is widely accepted that diets rich in polyunsaturated fats protect against heart disease. Recently, the Global Burden of Disease team reported that each year insufficient intake of omega-6 polyunsaturated fats, the most common subgroup of polyunsaturated fats, results in over 700 000 deaths from coronary heart disease.1 Or does it? A linked study by Ramsden and colleagues (doi:10.1136/bmj.i1246) adds to the doubts around the health benefits of replacing saturated fat with polyunsaturated fats.2
This new study re-examines recovered data from a double blind randomised controlled trial that took place 45 years ago. The Minnesota Coronary Experiment (MCE) followed 9423 participants from state mental hospitals and a nursing home for 4.5 years. The trial tested whether replacement of saturated fat with vegetable oil rich in linoleic acid (an omega-6 polyunsaturated fat) reduces the risk of coronary heart disease and death through a reduction in serum cholesterol concentration.
McKenzie-Mohr and Associates, based in Fredericton, Canada, provides online forums where information regarding fostering sustainable behavior and community-based social marketing can be freely exchanged.
This book is about making the transition gracefully. It provides a comprehensive introduction to community-based social marketing and how it is being applied throughout the world to foster sustainable behavior. It introduces the five steps of communitybased social marketing (selecting behaviors, identifying barriers & benefits, developing strategies, conducting a pilot, and broad-scale implementation), and showcases numerous programs illustrating its use. In this third edition, each chapter has been updated. Further, Selecting Behaviors has been added as a new first step in community-based social marketing. As well, a new behavior change tool—social diffusion—has been added to the array of tools already covered.
Protecting health, saving lives—millions at a time” is the motto of the Johns Hopkins Bloomberg School of Public Health. Although not the principal motivation for or lesson from the assessment by Chetty and colleagues published in JAMA,1 encouraging prospects for community health strategies are suggested by the findings in this article on income and life expectancy.
In an impressive analysis based on mortality data and deidentified tax records with more than 1.4 billion person-year observations and nearly 7 million deaths among individuals living in the United States during the 15 years between 1999 and 2014, Chetty et al confirm the long-observed association between higher income and longer life expectancy, as well as the recent increase in the gap in life expectancy between the richest and poorest 5% of the US population.1 Looking specifically at the lowest income quartile, Chetty et al also found little association between life expectancy and various measures of access to medical care, physical environments, employment conditions, or levels of income inequality.
James discusses conceptual models to understand health promotion. This includes Tannahill's model, Beattie's model and Naidoo and Wills' typology of health promotion. Other conceptual models in health promotion are available!
University of Melbourne Professor Rob Moodie and colleagues from the Obesity Policy Coalition and The Australian Health Policy Collaboration have issued a frank assessment of the health promotion landscape in today’s Medical Journal of Australia. The authors say Australia is losing the war against alcohol and weight-related illnesses and lacks a comprehensive approach to prevention.
L'assureur français Axa a décidé lundi de se débarrasser de ses propres actifs liés au tabac, qui pèsent environ 1,8 milliard d'euros, une grande première dans le secteur de l'assurance saluée par des défenseurs de la lutte contre le tabagisme et des promoteurs de l'investissement durable.
"La poursuite de nos investissements dans des entreprises de l'industrie du tabac n'a plus de sens", a expliqué l'Allemand Thomas Buberl, qui prendra les rênes du groupe dès septembre.
Axa, dont l'ensemble des primes santé s'est élevé à "près de 12 milliards d'euros" en 2015, est le "premier assureur global" à faire ce choix, a affirmé à l'AFP un porte-parole de l'entreprise.
Le groupe, qui se présente comme un "assureur santé et investisseur responsable", souhaite jouer un rôle dans la "prévention" et "soutenir les efforts des gouvernements" de la planète pour enrayer le tabac et ses effets désastreux sur la santé, selon un communiqué.
"Cette décision a un coût, mais notre conviction est claire: le coût humain du tabac est dramatique, son coût économique est énorme", écrit M. Buberl dans ce document.
Axa, qui avait annoncé le retrait de ses investissements dans le secteur du charbon à hauteur d'environ 500 millions d'euros, il y a tout juste un an en vue de la COP21, va cette fois encore plus loin dans sa politique d'investissement responsable.
La compagnie d'assurances, qui s'est engagée l'an dernier à tripler ses investissements "verts" d'ici 2020, va "immédiatement céder" les actions qu'elle détient dans des entreprises du secteur du tabac, et dont la valeur actuelle s'élève à environ 200 millions d'euros.
Editor's Note: PLOSBLOGS invited independent science journalist Beth Skwarecki to assess and contextualize the controversy which errupted in the US surrounding last month's release of Vaxxed, a documentary film made by and about anti-vaccine proponent and discredited doctor Andrew Wakefield. Our purpose in publishing the post that follows is not to review this film (problematic in any event since preview copies were not made available to press), but rather to provide a context for the reignited debate about vaccines that it has already provoked--and may still cause as its distribution expands to Asia. We want to help our readers--including parents attempting to make the correct decision about vaccinating their children, public health providers responding to vaccine hesitancy on the part of worried parents and public health researchers charged to provide evidence-based guidance on best practices for communicating vaccine efficacy and safety--to counter the current re-emergence of anti
Réseaux sociaux et pros de santé, ça vous évoque quoi ?
Les réseaux sociaux ont pris une place croissante dans la vie des Français ces dernières années et les professionnels de santé n’y échappent pas. De plus en plus de communautés de médecins, infirmières ou pharmaciens émergent sur le web, de façon structurée avec des plateformes dédiées ou de manière spontanée et informelle sur les médias sociaux existants (groupe Facebook ou LinkedIn, hashtag sur twitter…).
On constate aujourd’hui que les professionnels de santé, et notamment les médecins, ont de moins en moins de temps pour se rencontrer et échanger. Les réseaux sociaux répondent donc à différents besoins importants comme : la création d’un réseau de partenaires dans le cadre des parcours de soins (notamment pour les jeunes praticiens), le partage d’expertise et d’avis sur des cas patients ou l’échange autour de l’actualité médicale.
One of the subtler sleights of hand used by obesity crusaders is to talk about obesity while using figures that refer to people who are obese or overweight. Health reporters do it all the time and subeditors frequently put the word ‘obesity’ in the headline when the story is actually about people who are overweight (see here and here, to pick two examples at random).
Since there are more overweight people than there are obese people, the effect — and probably the intention — of this blurring of the lines is to inflate the number of supposed victims of the obesity ‘epidemic’. A quarter of Britons are obese, but if you add in people who are merely overweight this rises to 60 per cent.
I am not at all surprised that new Cochrane evidence showed yoga may be beneficial to those with asthma. I am a devoted yogi who has practised a combination of hot power and bikram yoga about twice a week for the past two years.
As more new drugs are bred in little biotechs, executives at giant firms are decamping to startups.
As a vice president of the $38 billion (sales) French drug company Sanofi, Victoria Richon witnessed constant reorganizations that affected her oncology drug development program. Teams shuffled, priorities shifted, and processes changed. She says she spent far less time on drug discovery and far more time sorting out the changes and persuading committees to keep her programs going. “That’s just the nature of a big company,” says Richon, whose 28-year career has included roles at cancer research centers and Merck MRK-0.44%.
Promuovere il consumo di cibo sano: un nuovo modello di marketing sociale per identificare e promuovere politiche basate sulle evidenze, per la promozione della salute e la prevenzione di malattie.
Il Community-based prevention marketing (CBPM) applica strategie e tecniche del marketing alla progettazione, all’implementazione e alla valutazione di programmi o politiche per la promozione della salute o per la prevenzione di malattie. Data la mancanza di un quadro sistematico per l'identificazione, la selezione e la promozione di politiche basate sull'evidenza, risulta necessario un cambio di prospettiva.
Nell’articolo “Community-Based Prevention Marketing for Policy Development: A New Planning Framework for Coalitions” apparso sulla rivista Social Marketing Quarterly (SMQ) (1) viene descritta l’adozione e l’applicazione pratica di un nuovo modello di riferimento: il Community-Based Prevention Marketing for Policy Development (CBPM-Policy Development) con l’obiettivo ultimo di migliorare la capacità della Comunità nell’identificare e promuovere politiche basate sulle evidenze.
Il progetto, guidato dai principi di ricerca/azione, ha rafforzato un legame già esistente tra i ricercatori universitari esperti di marketing sociale del Florida Prevention Research Center e l’insieme di partner della Tweens Nutrition and Fitness Coalition, impegnati da anni nella prevenzione dell’obesità infantile.
Il risultato di questa partnership accademica consiste in un nuovo modello di riferimento da otto punti così intitolati: 1.“Creare le basi”, 2.“Che cosa dovremmo cambiare?”, 3.“Quale politica dovremmo promuovere?”, 4.“Identificare il pubblico”, 5.“Ascoltare”, 6.“Sviluppare un piano strategico”, 7.“Monitorare e valutare”, 8.“Stiamo seguendo il piano?”.
A culturally sensitive lifestyle intervention showed promise at motivating Latinas living in the U.S. to eat better and exercise more by connecting healthy-living behaviors with the lives of saints and prominent religious figures, new studies found.
Several recent papers about the project, including a new study published in the Journal of Aging and Health, add to a growing body of research that indicates health interventions may have greater success promoting lifestyle changes among the nation’s rapidly growing Latino population if the content is culturally sensitive, integrating the spiritual and family values that are central to these women’s lives.
Objective To determine whether increasing calcium intake from dietary sources affects bone mineral density (BMD) and, if so, whether the effects are similar to those of calcium supplements.
Design Random effects meta-analysis of randomised controlled trials.
Data sources Ovid Medline, Embase, Pubmed, and references from relevant systematic reviews. Initial searches were undertaken in July 2013 and updated in September 2014.
Eligibility criteria for selecting studies Randomised controlled trials of dietary sources of calcium or calcium supplements (with or without vitamin D) in participants aged over 50 with BMD at the lumbar spine, total hip, femoral neck, total body, or forearm as an outcome.
Results We identified 59 eligible randomised controlled trials: 15 studied dietary sources of calcium (n=1533) and 51 studied calcium supplements (n=12 257). Increasing calcium intake from dietary sources increased BMD by 0.6-1.0% at the total hip and total body at one year and by 0.7-1.8% at these sites and the lumbar spine and femoral neck at two years. There was no effect on BMD in the forearm. Calcium supplements increased BMD by 0.7-1.8% at all five skeletal sites at one, two, and over two and a half years, but the size of the increase in BMD at later time points was similar to the increase at one year. Increases in BMD were similar in trials of dietary sources of calcium and calcium supplements (except at the forearm), in trials of calcium monotherapy versus co-administered calcium and vitamin D, in trials with calcium doses of ≥1000 versus <1000 mg/day and ≤500 versus >500 mg/day, and in trials where the baseline dietary calcium intake was <800 versus ≥800 mg/day.
Conclusions Increasing calcium intake from dietary sources or by taking calcium supplements produces small non-progressive increases in BMD, which are unlikely to lead to a clinically significant reduction in risk of fracture.
