L’obésité, de plus en plus répandue dans les zones rurales
Une équipe de chercheurs, sous la direction du professeur Majid Ezzati, de l’université Imperial College London, a passé au crible les données de 112 millions d’individus dans 200 pays. Il en ressort que sur la période 1985-2017, l’indice de masse corporelle (IMC, qui permet de mesurer la corpulence d’un individu en rapportant son poids à sa taille) a augmenté en moyenne de 2 kg/m2 chez les femmes et de 2,2 kg/m2 chez les hommes, soit une hausse de 5 kg à 6 kg par individu en moyenne.

Plus de la moitié de cette hausse (55 %) est issue des populations rurales. Dans les pays à plus faibles revenus, c’est parfois plus de 80 % de la hausse de l’IMC qui provient des campagnes. Partout dans le monde, exception faite de l’Afrique subsaharienne, l’obésité y progresse aussi vite, voire plus vite, que dans les villes.

How does exercise treatment compare with antihypertensive medications? A network meta-analysis of 391 randomised controlled trials assessing exercise and medication effects on systolic blood pressure | British Journal of Sports Medicine
Results We included a total of 391 RCTs, 197 of which evaluated exercise interventions (10 461 participants) and 194 evaluated antihypertensive medications (29 281 participants). No RCTs compared directly exercise against medications. While all medication trials included hypertensive populations, only 56 exercise trials included hypertensive participants (≥140 mmHg), corresponding to 3508 individuals. In a 10% random sample, risk of bias was higher in exercise RCTs, primarily due to lack of blinding and incomplete outcome data. In analyses that combined all populations, antihypertensive medications achieved higher reductions in baseline SBP compared with exercise interventions (mean difference −3.96 mmHg, 95% CrI −5.02 to −2.91). Compared with control, all types of exercise (including combination of endurance and resistance) and all classes of antihypertensive medications were effective in lowering baseline SBP. Among hypertensive populations, there were no detectable differences in the SBP-lowering effects of ACE-I, ARB, β-blocker and diuretic medications when compared with endurance or dynamic resistance exercise. There was no detectable inconsistency between direct and indirect comparisons. Although there was evidence of small-study effects, this affected both medication and exercise trials.

Conclusions The effect of exercise interventions on SBP remains under-studied, especially among hypertensive populations. Our findings confirm modest but consistent reductions in SBP in many studied exercise interventions across all populations but individuals receiving medications generally achieved greater reductions than those following structured exercise regimens. Assuming equally reliable estimates, the SBP-lowering effect of exercise among hypertensive populations appears similar to that of commonly used antihypertensive medications. Generalisability of these findings to real-world clinical settings should be further evaluated.

Les gaz lacrymogènes : dangereux pour la santé, mais... silence d’État !
À l’Hôpital d’instruction des Armées du Val-de-Grâce, Frank Ceppa, qui a écrit sur la toxicologie des armes, le reconnaît : « Je n’ai pas d’étude épidémiologique. Je donne un cours magistral dans une optique militaire aux personnels confrontés à ce type d’armes. J’évoque les risques accrus en milieu confiné, comme des réactions de stress respiratoire aigu, en cas de forte concentration, selon le nombre de munitions au mètre carré, mais je n’ai pas d’élément chiffré ni de littérature précise sur les symptômes. »

« On est beaucoup plus exposé que les manifestants mais on n’a aucun suivi pulmonaire, dermatologique ou ophtalmique, note Alexandre Langlois, du syndicat Vigi. À part la visite périodique de la médecine du travail, très succincte : on nous prend la tension, on passe sur la balance, on nous demande si ça va et c’est tout. » « Le code du CHSCT [comité d’hygiène et de sécurité] ne s’applique pas au volet répression de la fonction publique », dit Johan Cavallero, délégué national Alliance pour les CRS.

Electric Bikes for Fitness - Training With E-Bikes
Getting an e-bike can dramatically increase how often you ride, according to a recent survey of nearly 1,800 e-bike owners in North America. Before owning an e-bike, 55 percent of the respondents said they rode daily or weekly. After getting an e-bike, that number soared to 91 percent riding daily or weekly. More striking, 94 percent of non-cyclists rode daily or weekly after getting an e-bike—nearly every single one of them!...

For many e-bike owners, their e-bike doesn't replace their traditional bike; it replaces their car. That same e-bike survey found that owners replaced 46 percent of their car commutes and 30 percent of their driving errands with e-bike rides. All you need is a great commuter bag to carry your stuff, and you’re set. Nobody’s fitness is devalued by that.
E-bike riding delivers health benefits.

If you’re straight off the couch, the health gains of e-biking are significant. In one study, when Colorado University researchers gave otherwise inactive people e-bikes and told them to to ride a minimum of 40 minutes a day, three days a week, the volunteers willingly rode beyond the minimum, boosted their fitness, improved their blood sugar levels, and trimmed some fat in just one month.

Testés, nos enfants sont tous contaminés - Marie Claire
Nos certitudes sur les bienfaits de cette agriculture vacillent. Pour le toxicologue médical Nouredine Sadeg, président du comité scientifique de ToxSeek, cette coïncidence alimentaire est "phénoménale ! C'est une donnée difficile à trouver, les sources sont tellement diverses". Quant aux interrogations sur les dérives du bio, il tempère : "Un vin bio peut contenir des traces de pesticides, mais sachez qu'un vin non bio subit 50 à 80 épandages. L'Etat français ne peut pas tout contrôler. Surtout que, pour éviter de dépasser le seuil autorisé, la stratégie consiste à ne plus utiliser un pesticide à forte dose mais un mélange d'une vingtaine à faible dose. Les pesticides touchent aujourd'hui 100 % de la population. Il y a cinquante ans, les quantités produites par l'industrie étaient infiniment plus petites. Le vrai problème existe depuis quinze ans, c'est récent."

The forensic pathologist who got PTSD: ‘Cutting up 23,000 dead bodies is not normal’ | Science | The Guardian
Shepherd’s career as one of the UK’s most distinguished forensic pathologists saw him involved in disasters from the Hungerford shootings to the Bali bombings, and in high-profile cases from Harold Shipman to Stephen Lawrence...
it wasn’t a particular incident that left him immobilised by dread, struggling with sleep and plagued by panic attacks. Instead, it was the gradual accumulation of stress from 30 years confronting violence and the grave, the steady buildup of emotional damage from putting 23,000 dead bodies under the knife...
Shepherd’s mother succumbed to the heart condition that had dogged her for years in 1962, when he was only nine. As well as doing all the shopping and cooking, Shepherd says his father unlocked stores of kindness and affection that were often untapped in men of his generation. But when a friend brought a copy of Simpson’s Forensic Medicine into school, Shepherd found himself fascinated by the gallery of stranglings, knifings, shootings and electrocutions the textbook contained. Between those tatty red covers, the worst that could happen – the terrible thing that had, in fact, already happened – was laid out, anatomised and dissected...

While he prided himself on his ability to switch between mortuary and home, from objective investigator to loving husband and father, his marriage was beginning to show signs of strain, eventually collapsing in 2007. Although his wife would ask him to “show some emotion”, he says, “I hadn’t realised that it was so tightly screwed down. I was blocking the emotion that was bad, but I was also blocking the emotion that was good.”

ACS Advocates a Consensus Strategy to Prevent Injury, Disability, and Death from Firearms
The ACS COT’s Consensus Strategy views firearm injury and mortality in the larger context of violence toward oneself or others, which is a major cause of unnecessary injury and death in the United States, claiming on average 175 American lives every single day.*

“To reduce death and disability associated with firearm injuries, we have to think about the strategies that cover the entire spectrum of violence-related events: how firearms are stored in the home, recognition that people who are at risk of self-harm or domestic violence should not have access to weapons, and addressing the causes of interpersonal violence. These strategies don’t get a lot of attention. These are not controversial ideas. All are achievable and could make a huge impact in terms of reducing injury, disability, and death,” said Eileen M. Bulger, MD, FACS, Seattle, Wash., current ACS COT Chair.
Violent Intentional Injuries and Deaths Are a Neglected Public Health Crisis

In 2016, the most recent year for which data are available, a firearm was involved in 51 percent (22,938) of suicides and 75 percent (14,415) of homicides. Since 1999 there has been a 17 percent increase in firearm-related intentional injury death rates; over the same time period, there was a 22 percent decrease in traffic-related deaths.*

Since 2014, the ACS COT has been engaged in a firearm-injury prevention consensus-building project that involved surveys of its members and the ACS Board of Regents and Board of Governors, town hall meetings, and outreach to a broad group of stakeholder organizations.

We’re in a new age of obesity. How did it happen? You’d be surprised | George Monbiot | Opinion | The Guardian
Others insisted that the cause is a decline in manual labour. Again, this seems to make sense, but again the data doesn’t support it. A paper last year in the International Journal of Surgery states that “adults working in unskilled manual professions are over four times more likely to be classified as morbidly obese compared with those in professional employment”.

So how about voluntary exercise? Plenty of people argued that, as we drive rather than walk or cycle, are stuck to our screens and order our groceries online, we exercise far less than we did. It seems to make sense – so here comes the next surprise. According to a long-term study at Plymouth University, children’s physical activity is the same as it was 50 years ago. A paper in the International Journal of Epidemiology finds that, corrected for body size, there is no difference between the amount of calories burned by people in rich countries and those in poor ones, where subsistence agriculture remains the norm. It proposes that there is no relationship between physical activity and weight gain. Many other studies suggest that exercise, while crucial to other aspects of good health, is far less important than diet in regulating our weight. Some suggest it plays no role at all as the more we exercise, the hungrier we become.

Patrick reported that ways of taking Cycle Active forward are currently being sought. One possibility is the Finsbury Park Regeneration Scheme might take the project on. Also someone is needed to work on the administration, and it is possible that this could be a paid position.

The project was set up 2 years ago to teach people to ride bicycles and to improve their skills. There is money and equipment for the project to continue, if anyone is willing to take it on.

Douglas reported on health promotion progress. After all the optimism of our bid for Health Action Zone cash to promote cycling for recovering cardiac sufferers, it turns out that there is just £40 grand to support cardiovasculation health promotion in Hackney, most of which is going to support gym-based activities. There is, however, a chance of a small amount of seed money to go towards the training of cycle trainers, which will be better than nothing.

The inconvenient truth about cancer and mobile phones | Technology | The Guardian
The World Health Organisation in 2011 would classify mobile phone radiation as a “possible” human carcinogen and the governments of the United Kingdom, France and Israel issued warnings against mobile phone use by children. Nevertheless, the industry’s propaganda campaign would defuse concern sufficiently that today three out of four adults worldwide have mobile phones, making the wireless industry among the biggest on Earth.

The key strategic insight animating corporate propaganda campaigns is that a given industry doesn’t have to win the scientific argument about safety to prevail – it only has to keep the argument going. Keeping the argument going amounts to a win for industry, because the apparent lack of certainty helps to reassure customers, fend off government regulations and deter lawsuits that might pinch profits.

Central to keeping the scientific argument going is making it appear that not all scientists agree. Towards that end, and again like the tobacco and fossil-fuel industries, the wireless industry has “war-gamed” science, as a Motorola internal memo in 1994 phrased it. War-gaming science involves playing offence as well as defence – funding studies friendly to the industry while attacking studies that raise questions; placing industry-friendly experts on advisory bodies such as the World Health Organisation and seeking to discredit scientists whose views differ from the industry’s.

Promoting cycling in cities can tackle obesity | Imperial News | Imperial College London
The study, published in the journal Environment International, also finds that riding an electric bike (e-bike) is associated with a higher BMI as compared to regular cyclists. In ascending order, cyclists have the lowest BMI, then walkers, public transport users, motorcyclists, users of an electric bike, and finally car drivers, who have the highest BMI.

By following over 2000 urban dwellers over time, the team found that men who switch from car driving to cycling for their daily travel lose on average 0.75 kg of weight, with an average decrease in BMI of 0.24. For women, this was a little bit less.

Do lesbians have better sex than straight women? | Life and style | The Guardian
When men ejaculate, most need to take a breather for their erection to make a comeback (this is known as the “refractory period”). On the other hand, women can orgasm in waves. The clitoris has 8,000 nerve endings – double that of the penis glans – and its sole purpose appears to be providing pleasure. Women’s orgasms last for an average of 20 seconds, while men’s last eight. The most orgasms recorded in an hour for a woman is 134 (16 for a man). This makes it especially sad that so many heterosexual women are reporting understimulating sex lives.

So, for those women who are not coming endlessly – how can they improve their sex lives, whoever they may be with? As well as Ross’s advice to masturbate a lot, the Kinsey Institute recommends more oral sex, better relationships, “sexy talk”, asking for what you want in bed and trying new positions, among other things.

Feeding your baby solids early may help them sleep, study suggests | Life and style | The Guardian
More than 1300 healthy breastfed three-month-olds were split randomly into two groups in one the babies were exclusively breastfed until they were six months old – as current guidelines recommend – while children in the other group were breastfed and given solid foods, including peanuts, eggs and wheat, from the age of three months, in addition to breastfeeding. After six months babies in both groups were eating a range of solids.

The children’s health and behaviour was followed for three years, with their sleep and consumption of solid food tracked by families through questionnaires.

While not all babies were kept to their allotted regime, on average, babies who were in the breastfeeding only group were first introduced to solids at around 23 weeks, while those in the other group encountered the foods at around 16 weeks

The results, based on data from 1,162 infants and taking into account factors such birth weight and whether children had eczema, reveal babies introduced to solids from three months slept, on average, two hours more a week at the age of six months, than the babies who were only breastfed. They also woke around two fewer times at night per week at six months and had just over 9% fewer incidents of waking up during the night over the course of the study.

The team found that the more closely parents stuck to the early introduction programme, the stronger the effect.

Facebook knows a ton about your health. Now they want to make money off it.
Let’s say you like a Facebook page devoted to breast cancer survivors. It has been a useful forum for comparing treatment options with others who have dealt with similar health issues. There’s only one problem: Facebook has now categorized you as a patient, and you constantly receive precisely targeted ads about cancer services available near you. They are showing up on your computer screen at work, for all your co-workers to see, right when you’re up for a big promotion...

In early April, CNBC reported that Facebook recently launched a project based in its secretive “Building 8” group to get hospitals to share anonymized patient data with them. The project was reportedly put on hold in the wake of the current scandal, but the stated plan was to match hospitals’ patient data on diagnoses and prescription information with Facebook so the company could combine that data with its own to construct digital profiles of patients.

Poultry and nuts

Turkey and chicken contain high levels of tryptophan, which also boosts serotonin. “Foods that are high in tryptophan and vitamin B6 will help you make melatonin, the sleep hormone,” says Nerina Ramlakhan, sleep expert and author of Fast Asleep, Wide Awake. Other good sources of both are beans, lentils, cheese, tofu, tuna, eggs, whole grains, nuts and seeds.

After their attacks on climate science, industrial lobbyists target the scientific evidence on air pollution - Multinationals Observatory
Science under the influence

And obviously, there is the case of Michel Aubier. This eminent respiratory physician cruised the television studios downplaying the dangers of air pollution, only to later reveal that he was also a paid consultant to Total (read our article). In 2012, Aubier published an Académie de médecine report—widely cited by industry—entitled “Impact sanitaire des particules diesel : entre mythe et réalité ?” (The health impacts of diesel particulates: between myth and reality?), that promoted the merits of particle filters. In 2015 he had also testified along the same lines to a senatorial enquiry, claiming that the number of cancers linked to pollution was "extremely few". On both occasions he neglected to mention his pecuniary involvement with a multinational corporation whose primary business is the sale of petrol and diesel. In July 2017 he received a suspended six-month prison sentence and a €50,000 fine for failing to declare this conflict of interest to the Senat when asked.

Women’s saddle issues
One of the major contributing factors to saddle discomfort and health issues we did discover was the UCI ruling that saddles were only allowed a tilt of less than 2.5 degrees with a 0.5 degree margin of error. We presented our findings to the UCI and they have since increased the angle of tilt to nine degrees with a tolerance of one degree. This has had a major impact on rider health, for both men and women, across the sport.

Once seniors are too old to drive, our transportation system totally fails them - Vox
Drivers are way more likely to be involved in fatal crashes past the age of 75. And for those 85-plus, the data is even worse than it is for teens.

This is mostly because in the event of a crash, older drivers are more likely to die from injuries than younger ones. But it's partly because older drivers have deteriorating vision and reaction time, which leads to more crashes overall.

Why I — Usually — Refused to Wear Condoms: On Consent, Pleasure, and Alternatives to Intercourse
In my experience, even the best premium condoms result in a 90–95% reduction in sensation, a loss of feeling so severe as to make it difficult to impossible to stay hard. In my experience, a few partners were often like Anna — convinced that it’s a scam, that I was trying to wriggle out of using contraception. When I did lose my erection with a condom on, I was sometimes accused of being passive-aggressively manipulative, “punishing” the girl for insisting I wear one.

When I was lucky, some women were all up for doing those other fun, hot things besides intercourse.

Walking Study Corroborates Hippocrates’s Prescriptive Wisdom | Psychology Today
More specifically, Patel and co-authors concluded, “In older adults, walking below minimum recommended levels (>150 minutes per week) is associated with lower all-cause mortality compared with inactivity. Walking at or above physical activity recommendations is associated with even greater decreased risk.”

Traditionally, public health guidelines have recommended that adults engage in 150 minutes of moderate-intensity exercise or 75 minutes of vigorous-intensity physical activity per week. However, a groundswell of new research suggests that people can reap significant psychological and physical health benefits with much less exercise than previously recommended. For example, another October 2017 study suggests that just 60 minutes of exercise per week—at any intensity—helps prevent against future depression.

Brain pollution: Evidence builds that dirty air causes Alzheimer’s, dementia | Science | AAAS
an 11-year epidemiological study to be published next week in Translational Psychiatry, USC researchers will report that living in places with PM2.5 exposures higher than the Environmental Protection Agency’s (EPA’s) standard of 12 µg/m3 nearly doubled dementia risk in older women. If the finding holds up in the general population, air pollution could account for roughly 21% of dementia cases worldwide, says the study’s senior author, epidemiologist Jiu-Chiuan Chen of the Keck School of Medicine at USC.

Deepening the concerns, this month researchers at the University of Toronto in Canada reported in The Lancet that among 6.6 million people in the province of Ontario, those living within 50 meters of a major road—where levels of fine pollutants are often 10 times higher than just 150 meters away—were 12% more likely to develop dementia than people living more than 200 meters away.

A Father Describes Saving His Daughter From U.S. Bombardment of Mosul
airstrike from U.S.-led coalition forces bombing Islamic State fighters.

Corpses were everywhere in the ruins of the building; more than 200 people were reportedly killed. Ali’s wife was among them, but he wouldn’t know that until Iraqi civil defense forces found her body later that day. Ali heard the sound of a child groaning underneath the rubble. It was his daughter, Awra. Her body was charred black with severe burns, and shrapnel had pierced through the side of her head, cutting across her face, and sealing her eyes shut. Miraculously, she was breathing...
Doctors treated Awra’s infections and set her broken leg in a cast. A few days ago, they operated on her to dislodge a piece of shrapnel from her eye, restoring her vision for the first time since the airstrike.

Though her face is still scarred from burns and shrapnel cuts, Awra is enjoying her newly-recovered sense of sight

John Snow and the Broad Street Pump: On the Trail of an Epidemic
On 7 September 1854, Snow took his research to the town officials and convinced them to take the handle off the pump, making it impossible to draw water. The officials were reluctant to believe him, but took the handle off as a trial only to find the outbreak of cholera almost immediately trickled to a stop. Little by little, people who had left their homes and businesses in the Broad Street area out of fear of getting cholera began to return.

Despite the success of Snow’s theory in stemming the cholera epidemic in Soho, public officials still thought his hypothesis was nonsense. They refused to do anything to clean up the cesspools and sewers. The Board of Health issued a report that said, “we see no reason to adopt this belief” and shrugged off Snow’s evidence as mere “suggestions.”

Mortality from Diesel Car Pollution in the UK | Energy Matters
On Tuesday 4th April Channel 4 News in the UK carried a report on the impact of pollution from diesel cars upon UK mortality. It was claimed that pollution from diesel cars accounted for 40,000 excess deaths in the UK each year: 29,000 down to particulate matter (PM2.5) and 11,000 down to nitrogen oxides (NOx). The source of the statistics was a report from the Royal College of Physicians called Every breath we take: the lifelong impact of air pollution published in 2016. I decided to delve into the statistics and conclude that PM2.5 pollution from diesel cars may reduce life expectancy by between 2 and 22 days. Fake science and fake news is getting us into deep trouble...
The following story covered air pollution in UK cities, in particular NOx (nitrogen oxides) and soot emissions from the engines of diesel cars, that was reported to be prematurely killing 40,000 UK citizens per year!

Do the Health Benefits of Cycling Outweigh the Risks?
On average, the estimated health benefits of cycling were substantially larger than the risks of cycling relative to car driving. For the society as a whole, this can be even larger because there will be a reduction in air pollution emissions and eventually fewer traffic accidents. Policies stimulating cycling are likely to have net beneficial effects on public health, especially if accompanied by suitable transport planning and safety measures.

Wartime Demands Led to Sloppy Asbestos Use
For much of the 20th century, efforts to put the genie back into the bottle were thwarted by an asbestos industry that knew of the dangers of its commodity but constructed an elaborate conspiracy of silence.

What asbestos industry executives knew and when they knew it is a matter of public record, having come to light in the late 1970s after the first asbestos-disease lawsuits were filed.

But those executives had an accomplice: the U.S. government, which also knew asbestos was hazardous but turned a blind eye to the dangers throughout most of the 20th century...
working in an American shipyard during World War II would prove to be almost as deadly as fighting in the war.

During World War II, 16.1 million Americans were called to arms. The combat death rate was about 18 per thousand service members. About 4.3 million Americans worked in shipyards during the war. For every thousand wartime shipyard employees, about 14 died of asbestos-related cancer, and an unknown number died of an asbestos disease called asbestosis, or complications from it.

``In the highest levels of government, there was a conscious political decision to sacrifice lives of (shipyard workers) for the war effort,'' says Samuels, who, at 71, serves as vice president of a worldwide organization dedicated to advancing occupational health and safety issues.

Yoga to prevent cardiovascular disease | Cochrane
We found 11 trials (800 participants), none of them were large enough or of long enough duration to examine the effects of yoga on decreasing death or non-fatal endpoints.There were variations in the style and duration of yoga and the follow-up of the interventions ranged from three to eight months.The results showed that yoga has favourable effects on diastolic blood pressure, high-density lipoprotein (HDL) cholesterol and triglycerides (a blood lipid), and uncertain effects on low-density lipoprotein (LDL) cholesterol. None of the included trials reported adverse events, the occurrence of type 2 diabetes or costs. Longer-term, high-quality trials are needed in order to determine the effectiveness of yoga for CVD prevention.

Tai Chi to prevent cardiovascular disease | Cochrane
We found 13 trials, none of them were large enough or of long enough duration to examine the effects of tai chi on reducing cardiovascular deaths or non-fatal endpoints. There were variations in the duration and style of tai chi and the follow-up of the interventions ranged from three to 12 months. Due to the small number of short-term studies and the variability between them, we were unable to determine conclusively whether or not tai chi was beneficial at reducing cardiovascular risk in healthy adults and adults at increased risk of CVD, although beneficial effects for CVD risk factors were seen in some studies. None of the included studies reported on adverse events. Longer-term, high-quality trials are needed in order to determine the effectiveness of tai chi for CVD prevention.

Behaviour changes for dietary and physical exercise modification in overweight and obese adults | Cochrane
transtheoretical model (TTM) stages of change (SOC) to produce sustainable (one year and longer) weight loss in overweight and obese adults?...

The use of the TTM SOC in combination with diet or physical activity, or both, and other interventions in the included studies provided inconclusive evidence about the impact of such interventions on sustainable weight loss (mean difference in favour of the TTM SOC was between 2.1 kg and 0.2 kg at 24 months). However, other positive effects were noted, such as changes in physical activity and dietary habits that included increased exercise duration and frequency, reduced fat intake and increased fruit and vegetable consumption. The studies did not report other important outcomes such as health-related quality of life, illness (morbidity) and economic costs.

Overall, the quality of the evidence was low or very low.

Face-to-face interventions for promoting physical activity | Cochrane
Participating in insufficient amounts of physical activity leads to an increased risk of a number of chronic diseases, and physical and mental health problems. Regular physical activity should be a goal for all adults and can provide social, emotional and physical health benefits. The majority of adults are not active at recommended levels. We included a total of 10 studies recruiting 6292 apparently healthy adults in this review. The findings of the review indicate that interventions can successfully support adults' attempts to become active and fitter, for example with personal counselling and advice, feedback and offering choices of exercise, and supervision. Outcomes are improved if the intervention comprises a specified type of physical activity and is supervised by a non-health professional using a combination of group and individual approaches. New physical activity can be maintained for up to at least one year and does not increase the risk of falls or exercise related injuries. More research is needed to establish which methods of exercise promotion work best in the long term to encourage specific groups of people to be more physically active.

Non-pharmacological interventions for preventing secondary vascular events after stroke or transient attack | Cochrane
Non-pharmacological interventions (treatments that do not involve drugs) may play a role in preventing a secondary vascular event and reducing vascular risk factors. Only one randomized controlled trial was identified, involving 48 participants. Considering the small sample size and methodological limitation, no implications on the effectiveness of non-pharmacological interventions post-stroke can be drawn. Several ongoing trials will, in time, contribute to the current body of evidence. However, more research is needed.

Exercise for people with increased cardiovascular risk | Cochrane
One or more of the studies reported on total cardiovascular risk, low-density lipoprotein (LDL) and high-density lipoprotein (HDL) cholesterol, blood pressure, body mass index, exercise capacity, and health-related quality of life, but the results did not provide conclusive evidence of the effects of exercise in this population. The included studies did not assess smoking cessation or any adverse effects of the exercise intervention. We conclude that the evidence to date is entirely limited to small studies in terms of sample size, short-term follow-up, and high-risk of methodological bias, which makes it difficult to derive any conclusions on the efficacy or safety of the exercise carried out in the included trials on total cardiovascular risk, mortality, or cardiovascular events. It is necessary to conduct high-quality clinical trials that evaluate the effect of exercise on people with increased cardiovascular risk.

Lessons on Aging Well, From a 105-Year-Old Cyclist - The New York Times
Conventional wisdom in exercise science suggests that it is very difficult to significantly add to aerobic fitness after middle age. In general, VO2 max, a measure of how well our bodies can use oxygen and the most widely accepted scientific indicator of fitness, begins to decline after about age 50, even if we frequently exercise.

But Dr. Billat had found that if older athletes exercised intensely, they could increase their VO2 max. She had never tested this method on a centenarian, however.

Cycling and health promotion
Building walking and cycling into daily life is much more likely to be sustainable in the long term than gym based exercise prescription schemes.8 We own more bicycles than ever—an estimated 27 million in the United Kingdom—so why do we not use them? The most important deterrent that non-cyclists express is fear of motor traffic. The fear is exaggerated in comparison with the statistical likelihood of injury,9 but lowering the speed limit in towns to 20 mph would be a straightforward way of reducing it. Seventy per cent of motorists currently exceed the 30 mph limit in free flowing traffic. The government's recent road safety review passed responsibility for speed reductions to local authorities10—with no extra resources to implement them. Compounding this was an announcement by the Association of Chief Police Officers that it will standardise enforcement of the 30 mph limit at 37 mph. This may reflect the realpolitik of British roads, but it is irrational. We know that the difference between 20 mph and 37 mph is quite literally life and death.11 Those with a clear sighted view of road safety issues will continue to press this point.

The Economist found that counties with high rates of obesity, diabetes, alcohol intake, and lack of exercise — in other words, poor public health — accounted for 43 percent of Trump’s gains among Republicans compared to Mitt Romney, the Republican candidate for president in 2012.

And Trump won all 16 states with the highest mortality rates, according to a study from the University of Pittsburgh included in STAT’s On Call newsletter recently. “These data suggest that Trump voters were expressing dissatisfaction with real problems that included shorter lives and less healthy living conditions,” said Dr. Donald S. Burke, dean of the University of Pittsburgh’s graduate school of public health.

Let's first address the fundamental question of whether undocu­mented immigrants are a drain on our nation's resources. It is estimated that there are 11.4 million undocumented immigrants in the United States, 81% from Latin America. While their proportion has been declining over the past few years, Mexicans make up approximately 58% of the total, while immigrants from other Latin American countries account for the remaining 23%. At the same time, immigration from Asia, the Middle East and Africa is rising. Six states account for over 60% of unauthorized immigrants (Cali­fornia, Texas, Florida, New York, New Jersey and Illinois). Undoc­umented laborers make up a bit over 5% of the US workforce. Collectively, undocumented immigrants contribute approximately $12 billion per year in state, local and federal taxes, and this is expected to increase by $2.2 billion under the Obama Adminis­tration's proposed comprehensive immigration reform. Moreover, they pay an estimated $13 billion per year into Social Security, from which they receive no benefit.[1]

It is well known that in the USA, not everyone has equal access to health care. In fact, at 40%, undocumented Latinos have among the lowest levels of insurance coverage and thus are more likely to have to pay for health services out of pocket. They also use very little primary or secondary health care.[2] When they use primary health care, they typically seek services at busy, poorly funded community clinics or in more costly hospital emergency departments. These facilities can be of low quality and without sufficient resources to provide language-concordant care. Ironi­cally, while some of those 60% without insurance may receive indigent care, the services provided them in safety-net facilities are often subsidized by federal and state provisions—to which their taxes contribute.

Frontiers | The Synergistic Impact of Excessive Alcohol Drinking and Cigarette Smoking upon Prospective Memory | Addictive Disorders
The Cambridge Prospective Memory Test (CAMPROMPT) is a test of both time-based and event-based PM and was used here to measure PM. The CAMPROMPT was administered to 125 adults; an excessive alcohol user group (n = 40), a group of smokers who drink very little alcohol (n = 20), a combined user group (the “Polydrug” group) who drink excessively and smoke cigarettes (n = 40) and a non-drinker/low alcohol consumption control group (n = 25). The main findings revealed that the Polydrug users recalled significantly fewer time-based PM tasks than both excessive alcohol users p < 0.001 and smokers p = 0.013. Polydrug users (mean = 11.47) also remembered significantly fewer event-based PM tasks than excessive alcohol users p < 0.001 and smokers p = 0.013. With regards to the main aim of the study, the polydrug users exhibited significantly greater impaired time-based PM than the combined effect of single excessive alcohol users and cigarette smokers p = 0.033. However, no difference was observed between polydrug users and the combined effect of single excessive alcohol users and cigarette smokers in event-based PM p = 0.757.

300 million children live in areas with extreme air pollution, data reveals | Environment | The Guardian
Three hundred million of the world’s children live in areas with extreme air pollution, where toxic fumes are more than six times international guidelines, according to new research by Unicef.

The study, using satellite data, is the first to make a global estimate of exposure and indicates that almost 90% of the world’s children - 2 billion - live in places where outdoor air pollution exceeds World Health Organisation (WHO) limits.

Unicef warned the levels of global air pollution contributed to 600,000 child deaths a year – more than are caused by malaria and HIV/Aids combined.

There is no evidence that stretching helps to reduce or a type of pain that can show up a day or two after exercising – also called delayed onset muscle soreness (DOMS).

A 2011 review by Prof Herbert found that “muscle stretching, whether conducted before, after, or before and after exercise, does not produce clinically important reductions in delayed onset muscle soreness in healthy adults.”

Particulate air pollution and impaired lung function - F1000Research
Air pollution is associated with millions of premature deaths worldwide1, 25% of which are estimated to be respiratory in nature2, and is the world’s largest environmental health risk3. In an attempt to mitigate ambient exposure to air pollution, the Environmental Protection Agency (EPA) currently regulates six criteria air pollutants under the Clean Air Act4. Of the regulated pollutants, particulate matter (PM) has been extensively studied and associated with a myriad of adverse health outcomes, including an adverse impact on lung function in both children and adults5–7. PM is a complex mixture of liquid droplets and extremely small particles composed of organic and inorganic compounds7. PM less than 10 μg in aerodynamic diameter, designated by PM10, can penetrate conducting airways; PM2.5 (PM less than 2.5 μg in aerodynamic diameter) is composed of fine particles and can penetrate into the gas-exchanging regions of the lung6. Sources of ambient PM include construction sites, smokestacks, fires, power plants, and automobiles; the main sources of indoor PM include ambient PM, tobacco smoke, cooking, and heating appliances. PM causes lung inflammation and mucous secretion by acting on airway epithelial cells and alveolar macrophages and may lead to airway remodeling8.

Exhaust-ed Cyclists — Fireseeds North Infrastructure
Studies have concluded that cyclists are at a greater risk of illness due to the higher intake of pollutants from a higher breathing rate during exercise compared to a pedestrian walking [3,4]. Particles travel deeper into the lungs and have more severe health affects [2]. Researchers have also linked cancer [5] and heart risk [6] to the air pollution levels cyclists encounter and that diesel fumes are more harmful to cyclists than regular gasoline [4].
Separation Matters

A key factor in determining whether a right- or left-sided tailpipe has a greater impact on cyclists is whether or not the distance from a tailpipe to the cyclist is important and if there is a safe distance. In research investigating whether drivers or cyclists are more exposed to air pollutants, the results are conflicted. Some studies show that cyclists are more exposed than drivers [3], while others state that cyclists are less exposed [7,8]. Studies that suggested that cyclists are less exposed highlighted cyclists' ability to by-pass congestion and the partial separation of cyclists from traffic [3,9]. Since these studies suggest that a decrease in exposure for cyclists is due to physical separation from traffic, what does this mean for all the roads without separated cycling infrastructure and where cyclists may be stuck in grid-lock with vehicles? Studies also found that pedestrians were at a lower risk of exposure to pollutants than drivers and cyclists [6]. This supports the use of separated bike facilities such as bike lanes or multi-use paths in order for cyclists to avoid traffic and pollutants.

Les signataires sont des spécialistes reconnus des maladies respiratoires, chefs de différents services de pneumologie – hôpital de Créteil (94), de la Pitié-Salpêtrière (13e) – ou d’allergologie pédiatrique – Trousseau (12e) –, vice-doyen de faculté de médecine Pierre-et-Marie-Curie… Leur message est clair : "Il est urgent d’agir [contre la pollution de l’air]. Ne rien faire, c’est se rendre coupable de non-assistance à personnes en danger." Voici leur tribune ci-dessous :

Oui à des voies sur berge piétonnes de la Seine rive droite à Paris, une mesure utile à la préservation de la santé de tous

En France, la pollution de l’air extérieur entraine environ 48 000 décès prématurés chaque année. A Paris, elle entraine environ 2500 décès chaque année et retire plus de 2 ans d’espérance de vie à 30 ans. À l’échelle de la Métropole, ce sont 6600 décès qui seraient évitables chaque année.

Electro-sensibilité, le cri d’alarme des médecins
Souvent considérés comme phobiques ou paranoïaques, les électro-hypersensibles bataillent à faire reconnaître leur maladie, et donc la potentielle dangerosité des ondes électromagnétiques. Mais une étude parue en décembre 2015 pourrait changer la donne : elle a identifié des « marqueurs biologiques », c’est-à-dire des réactions spécifiques du corps à la maladie. Menée par le professeur Dominique Belpomme, l’étude a suivi sur la longueur plus de 500 patients atteints d’électro-hypersensibilité. En plus des analyses de sang et d’urine, qui ont montré certaines anormalités, le professeur a observé l’activité du cerveau : elle montre que certaines zones précises sont moins bien irriguées chez les patients électro-hypersensibles.

“The True Costs of Automobility: External Costs of Cars” | Road Danger Reduction Forum
Anyway, the amount of taxation raised by UK motorists – fuel duty and its associated VAT along with vehicle excise duty contribute around £38bn a year – is £10 billion less than the £48 billion estimated by the report’s authors to be the external costs of motoring.

And don’t forget that those costs do not include the health disbenefits to drivers, congestion, danger, visual intrusion, community disruption (with loss of children’s independent mobility), policing and road building, and parking space costs.

If anything one can argue that they are a significant underestimate.

Re: Vested interests doom puny healthcare interventions

Ogilvy et al's paper demonstrates the greatest weaknesses of the "evidence-based" approach rather neatly. They assume that motoring is a disease and that interventions must be found to cure it, without examining the social forces that led to the car use in the first place, or that sustain it now it is here.

They review various "interventions" that have tried to part the motor-dependent from their motors in favour of walking and cycling, and find they are weakly, or not at all, effective.

This is hardly surprising, given the massive social currents acting in the opposite direction: car advertising, predict and provide road transport policies, retail monoliths with giant car parks and other horrors of surburban planning. Together this alliance of big business, oil suppliers, motor manufacturers and civil engineers have a massive vested interest in the continued growth of motorised transport. Free travel on foot or by bicycle is an insult to those businesses, who will actively discourage it.

Those who have bought into this motor dependent lifestyle can be trusted to extend the infliction of motor tyranny on everyone else: motorists object to being taxed, though they are major pollutors, or confined by speed limits, though they killed 3,508 people in Britain last year, as they barge through towns and cities greeting their fellows with a snarl of the engine, a blast of the horn, and the acrid reek of their exhaust.

Undermining this metal-carapaced horde is rather difficult, tiresome, and boring, so I am glad I am well paid to do it. Any driver suffering from a condition in which lack of exercise is a factor: hypertension, obesity, stress, depression--most of the general practice caseload in fact, is told to sell their car and get a bike instead.

I do have my successes: I am particularly fond of the man in his fifties who came back for a followup appointment saying he wished he lived further from work so he had more time on his bike everyday, and a (no-longer-so-)depressed patient in her thirties who thanked me and said "I wish I'd taken cycling up years ago."

But when I look at the vested interests lined up against me--not least George W. Bush's latest oil grab--I realise I am pissing into the wind and wonder why I bother. I find doctors who continue to drive particularly depressing, take for example, the consultant car park at Bart's, or the two jokers above, arguing about a visit. Since when do you need a car to carry a briefcase?

Competing interests: I own five bikes and might sell one of them soon.

Prof Harrison's own analysis backs up figures in the Health Service Journal which suggest there have been 5.6% more deaths in England and Wales in 2015 than in the previous year - the biggest increase in the national death rate since the 1960s.

Though the final figures - which take changes in population size into account - will not be released by the Office for National Statistics until the summer, experts say more needs to be done to understand the reasons behind the spike and urge public health experts to focus on wider factors, not just influenza.

How Burgers and Fries Are Killing Your Microbial Balance
Humans can’t digest soluble fiber, so we enlist microbes to dismantle it for us, sopping up their metabolites. The Burkina Faso microbiota produced about twice as much of these fermentation by-products, called short-chain fatty acids, as the Florentine. That gave a strong indication that fiber, the raw material solely fermented by microbes, was somehow boosting microbial diversity in the Africans.
Indeed, when Sonnenburg fed mice plenty of fiber, microbes that specialized in breaking it down bloomed, and the ecosystem became more diverse overall. When he fed mice a fiber-poor, sugary, Western-like diet, diversity plummeted. (Fiber-starved mice were also meaner and more difficult to handle.) But the losses weren’t permanent. Even after weeks on this junk food-like diet, an animal’s microbial diversity would mostly recover if it began consuming fiber again.

News analysis: Cycling safety special report - Health News - NHS Choices
. "the increase in cycling [in London] also resulted in a large increase in cycling KSI"—just not true

There has been a rise in the number of cyclists killed or seriously injured (KSIs) over the past few years. The DfT estimates that the number of KSIs in 2012 was 32% higher than the average recorded for the 2005-2009 period.

This rise in KSI incidents has to be matched against the increasing number of people choosing to cycle. However, it is difficult to accurately measure the rise in either cycling journeys or the time and distance travelled.

The National Travel Survey (NTS) of 2012 estimated an increase of around 23% in the number of cyclists, compared to the 2005-2009 period. However, this is just an educated guess. While it is relatively straightforward to estimate car ownership, based on official data such as car registrations and tax records, no such robust data exists for cyclists. Therefore, it is important to put the current risk of cyclists being involved in a KSI incident in context.

Sitting down is no worse for you than standing up - Telegraph
Contrary to recent advice, the researchers found no discrepancy between the mortality rates of those who sat for long periods, versus those who stood for the same time.

Instead, the team from the University of Exeter concluded that the key aspect in terms of a person's health was their mobility while sitting or standing.

The findings contradict current NHS guidelines, which advise people to avoid sitting down where possible, and the contemporary slogan that 'sitting down is the new smoking'.

"Our study overturns current thinking on the health risks of sitting and indicates that the problem lies in the absence of movement rather than the time spent sitting itself" said study author Dr Melvyn Hillsdon.

Does promoting bicycle safety inadvertently discourage bicycling? - Opus
Two-hundred and twenty-eight bicyclist and non-bicyclist adults were randomly allocated to read safety-focused, health-focused, or control publicity materials and their immediate influences on perceived risks, health benefits and enjoyment of bicycling, and intention to bicycle, were measured. Health-focused materials significantly increased bicycling’s perceived health benefits amongst non-bicyclists (t(28) = 4.52, p = .0006) and had no influence on perceived risk; the safety-focused campaign had no effect on either perceived risks or health benefits for either group. Neither campaign measurably changed intentions to bicycle nor the perceived enjoyment of bicycling, both of which were clearly higher amongst bicyclists than non-bicyclists (Wilks’s λ = .49, F(1,210) = 218.02, p < .001, Wilks’s λ = .81, F(1,222) = 52.83, p < .001). The study suggests that safety-focused campaigns are unlikely to have any immediate effect on people’s perceptions and intentions to cycle; health-focused campaigns seem to make bicycling appear more beneficial to those who do not currently do it.

Assessing the Human Toll of Volkswagen’s Diesel Deception - The New York Times
The Volkswagen pollution, about 46,000 tons since 2009, is the equivalent of about 4 percent of the power plant pollution they measured, meaning it could be expected to cause an estimated 106 deaths if it had similar effects.

Everything We Know About the Volkswagen Emissions Scandal - Motor Trend
Volkswagen AG engineers admitted to the deception on September 3, 2015, after the EPA and CARB refused to certify 2016 Volkswagen and Audi four-cylinder diesel models for sale until the issue was resolved. According to the notice, Volkswagen AG engineers wrote two different programs into the engine computer, one for use during emissions testing and one for use at all other times. Additional software would monitor “various inputs including the position of the steering wheel, vehicle speed, the duration of engine operation and barometric pressure” in order to determine when the car was undergoing emissions testing. During a test, it would run the “dyno calibration,” which put emissions controls such as the lean NOx trap (all models) and selective catalyst reduction (AdBlue urea injection, 2012+ Passat only) into full effect. After testing, the computer would revert to the “road calibration,” which turned off the emissions controls resulting in more power and better real-world fuel economy, but at the expense of NOx emissions 10-40 times higher than the legal limit.

Vapotage et santé publique : la France négativiste | VAPYOU
A quelques jours des discussions sur la Loi de Santé au Sénat, la France confirme une position négativiste sur le vapotage au mépris de la santé publique…

« La cigarette électronique est un produit industriel, ce n’est pas un médicament. On ne connait pas encore les dangers de son utilisation, et il n’est pas encore démontré qu’elle est efficace pour arrêter de fumer. Mieux vaut s’abstenir. »

Ce « conseil » se retrouve allègrement copié/collé sur toutes les questions qui sont posées par des fumeurs qui s’interrogent sur la cigarette électronique sur le site Tabac Info Service. Comme si les substituts nicotiniques n’étaient pas des produits industriels, comme si les dangers, bien qu’inconnus malgré des centaines d’études, étaient inéluctables et prévisibles, comme si les 6 millions de personnes sevrés du tabac grâce au vapotage en Europe n’existaient pas (400 000 officiellement en France selon l’INPES, organisme gouvernemental)

Comment of the Week: Biking, fitness and weight loss are three different things -
Exercise does have beneficial effects on obesity, and cycling is exercise. Cycling is a particularly good exercise for overweight people, because it doesn’t stress the joints much.

It should be particularly noted that the overall metabolism of fit and sedentary people is not the same. Even short periods of regular exercise increase muscle mass and the muscles’ ability to metabolize fat. At rest, muscle is a more metabolically active tissue than adipose tissue, so the benefits are occurring even between bike rides. Big fit muscles burn more fat, 24/7.

All this is true whatever nasty things the childish are saying to each other this week.

I Asked My Mom Why She Didn’t Vaccinate Me
made me wonder whether vilifying anti-vaccine parents — as the press has done repeatedly this week — is a good strategy for increasing vaccine coverage. When parents make medical choices, good or bad, it’s for one simple reason: They’re trying to do the right thing for their kid. Refusing vaccination is not a political statement.
