Weight and mortality

first_imgIn January, when the Journal of the American Medical Association (JAMA) published a meta-analysis of 100 studies that probed the relationship between body mass index and mortality — studies that found slightly overweight people have lower all-cause mortality than normal weight and underweight people — media around the globe trumpeted the news.Many suggested that scientists had failed to understand something crucial about health, and questioned whether carrying extra weight might be healthier than being slim.“When I read the article I was somewhat taken aback. I wondered if I should send a ‘never mind’ note to all the people I’d taught about the risks of excess fat,” said Jeffrey S. Flier, dean of the Faculty of Medicine, at Harvard Medical School (HMS) and an authority on the biology of obesity and diabetes.He wasn’t alone. Many others were perplexed by the findings gathered by Centers for Disease Control (CDC) epidemiologist Katharine Flegal, which contradict a preponderance of research indicating that there is a direct correlation between the risk of mortality and being overweight once factors such as lower weight from cigarette smoking, chronic disease, and wasting from frailty in the elderly are taken into account.To clear up the confusion, Flier worked with Julio Frenk, dean of the Harvard School of Public Health (HSPH), to convene a panel of experts at HSPH on Feb. 20 to discuss the findings with the HMS and HSPH communities. Flegal, a senior scientist at the CDC’s National Center for Health Statistics, was invited to the event, but did not attend.Information in context“We live in an era of near-ubiquitous access to information,” Frenk said, “but the University has an important role to play in providing context and analysis to help people judge the value of information they are consuming, especially when there are equivocal or controversial findings.”The panelists evaluated Flegal’s findings and pointed out a number of methodological errors in the study that they said resulted in the artificial appearance of a protective benefit in being overweight or mildly obese.“When something sounds too good to be true, it’s usually not true,” said Frank Hu, HSPH professor of nutrition and epidemiology and HMS professor of medicine.Methodological errorsThe selection criteria that Flegal used for her meta-analysis ruled out high-quality studies of 6 million people (more than twice as many as were represented in her analysis), said Hu. These studies, in aggregate, show that the highest survival rates are in normal weight people, not the overweight, Hu said.The studies that Flegal did use included many samples of people who were chronically ill, current smokers and elderly, according to Hu. These factors are associated with weight loss and increased mortality.In other words, people are not dying because they are slim, he said. They are slim because they are dying—of cancer or old age, for example. By doing a meta-analysis of studies that did not properly control for this bias, Flegal amplified the error in the original studies.There is also no known biological basis for any protective effect from being overweight, the panelists said, citing studies that show a clear connection between being overweight and conditions such as hypertension and insulin resistance, which are risk factors for coronary heart disease, stroke and several cancers.“Even as you get near the upper reaches of the normal weight range, you begin to see increases in chronic diseases,” said JoAnn Manson, chief of the Division of Preventive Medicine, Brigham and Women’s Hospital, HMS Michael and Lee Bell Professor of Women’s Health, and HSPH professor of epidemiology. “It’s a clear gradient of increase. There is no evidence here of any global protective factor for being overweight.”Flegal responded in an email to the criticisms by saying that she stands by her findings, which she noted had withstood review by the CDC, the National Institutes of Health and the editors and four of five reviewers at JAMA. She said that her team looked at 7,000 articles already in the medical literature.“We explicitly included studies that were prospective studies of adults that looked at all-cause mortality with BMI measured or reported at baseline and that used the standard international categories of BMI … used by the World Health Organization and the U.S. government,” Flegal said.Credibility of sciencePanelists, however, expressed concern that much of the popular journalism and commentary about Flegal’s research could undermine the credibility of science, citing articles that show studies wavering between alternating conclusions, and opinion pieces suggesting that researchers have some conspiratorial interest in making people feel bad about their weight or lifestyle choices.Translating the nuances of these and other critically important findings to the public, practitioners and policy makers is part of the core mission of a university, Frenk said.“The role of the university is not to shy away from controversy but to embrace it. Protecting the credibility of science becomes very important,” Frenk said.Steven Heymsfield, the George A. Bray Jr. Endowed Super Chair in Nutrition and executive director of the Pennington Biomedical Research Center, who co-authored a JAMA editorial that accompanied Flegal’s findings, noted that BMI alone could not provide a definitive assessment of the health of any given individual.He said, “Misleading data on BMI and mortality conveys an erroneous message to the public and practitioners that being overweight does not have major consequences.”Walter Willett, the Fredrick John Stare Professor of Epidemiology and Nutrition and chair of the Department of Nutrition at HSPH, and HMS professor of medicine, said it is important for people to have correct information about the relationship between health and body weight.“If you don’t have the right goal you are very unlikely to end up in the right place,” Willet said.The panel was presented by the HSPH Department of Nutrition.

Chainsaw Safety

first_imgUniversity of Georgia Cooperative Extension is presenting chainsaw trainings designed to educate Georgia’s landscape and tree care workers on the safe use of chainsaws. The trainings will be offered between September and December at locations across the state. “A chainsaw is the most dangerous implement that you can buy in a store that does not require any training or a license. You don’t even need to read the manual to operate it,” said Ellen Bauske, public service associate with the UGA Center for Urban Agriculture. “(These) trainings are for people working in the tree care and landscape industry. Tree care workers are often dangerously comfortable with chainsaws. The landscape worker usually doesn’t use a chainsaw. Invariably, they’re inexperienced when they have to. These trainings are designed to get rid of bad habits and establish safe practices. ” The trainings are taught by North American Training Solutions, one of a handful of companies specializing in chainsaw safety training. The classes are approved by the Occupational Safety and Health Administration (OSHA) and funded through their Susan Harwood Training Program. There are four different trainings, each tailored to a different skill set when handling a chainsaw. “A surprising number of people cut down trees from ladders, which is extremely dangerous because you can’t get away from the tree or branch when it falls. We have a chainsaw and ladder safety training,” Bauske said. “We have chainsaw safety and working in the right-of-way. If you’re felling a tree in an urban area, you are invariably felling them around electrical wires. Electrocution is the No. 2 cause of death among tree care workers.” Other trainings focus on aerial lift operations and tree felling. The trainings are free, and lunch will be provided for a small fee. The next training is slated for Aug. 11 in Douglas County. It will focus on technical tree cutting and small tree felling. Other trainings include one in Chatham County, Sept. 1-2; in Brunswick on Sept. 3; in Troup and Spalding County, Sept. 24; in Fulton County, Sept. 30; in DeKalb County, Oct. 8; in Douglas County, Oct. 13; in Gwinnett County, Nov. 12 and Dec. 9 and Lowndes County (Dec. 10). “We are working on more trainings, so call your county agent to find out about the trainings near you.,” Bauske said.

Opinion: Atlantic Highlands Waterfront Property Battle Continues

first_imgNeighbors for Waterfront Preservation will appeal thissubdivision approval and in so doing, hopes set an important precedent forfuture developments.  As a community, wehave a choice.  Will we allow newdevelopments in flood zones, thereby endangering existing residents in theneighborhood?  Or, will we preserve theseareas for open space, public access, and a buffer for rising seas? Some members of the planning board felt otherwise, however: twomembers voted no and one abstained. Unfortunately, approval required only asimple majority, and now the developer has cleared his first hurdle.  This decision undermines efforts by thecommunity to preserve some or all of this property as open space, especially onthe waterfront, and it risks contributing to over-development on the JerseyShore. Now the fate of this unique property will be decided by the NJ DEP, thecourts, and, potentially, the Borough Council.  The Two River Times recently reported the Atlantic Highlands Planning Board approved a large subdivision plan for luxury waterfront homes on the 7-acre waterfront McConnell Property.  The developer, Steven Denholtz, and his attorney John Giunco, argued that the development was “variance and waiver free,” and that the hands of the Planning Board were tied, making approval fait accompli.  But apparently the developer has a shorter memory than therest of us. Mr. Denholtz’s professionals said that this waiver did not apply tohis application because the waterfront was already “developed.”  While it is true that the property onceserved as an oil transfer station with minimal infrastructure built toaccommodate the now defunct business, it was never subdivided or “developed”for residential use as the zone requires. The Borough Council’s obvious intent was to prevent new development inflood-prone areas, not to stop existing homeowners from rebuilding their flood-damaged homes. This stretch of waterfront has been abandoned for decades, andthe sea is taking back the old wooden bulkhead. Clearly, the developer should have requested a waiver to subdivide andbuild homes on this site.  The Boroughengineer neglected to address this issue in his original review letter, but inthe end sided with Denholtz, setting the stage for this potentially disastrous decision.  Local residents have numerous concerns about this project, including:the toxic legacy of the property; the failure of the developer and the planningboard to provide public access; the disregard for the historical significanceof the site; and the exclusion of the objector’s legal counsel in the planningprocess. One of the most substantial and immediate questions posed by thisdecision is: should new developments be allowed in flood zones?center_img This letter was first published in the Commentary section of the May 23-29, 2019 print edition of The Two River Times. Contributed by Benson Chiles, Neighbors for Waterfront Preservation A year after Super Storm Sandy when the borough sufferedmillions of dollars in damage to homes and property, the Atlantic HighlandsBorough Council updated its zoning ordinance design standards to require thatall new subdivision plans preserve all areas in the flood zone as openspace.  This action was a logical andmeaningful response to a devastating storm that no one in the Two River area issoon to forget.  last_img read more

DESORMEAUX’S EXAGGERATOR & BAFFERT’S MOR SPIRIT HEADLINE COMPETITIVE GRADE II, $400,000 SAN FELIPE STAKES AT 1 1/16 MILES

first_imgMOR SPIRIT: A better-than-looked 1 ½ length winner of the Grade III, 1 1/16 miles Robert B. Lewis Stakes here Feb. 6, he took the Grade I Los Alamitos Futurity at the same distance on Dec. 19. Although he’s proven a bit reluctant on occasion in the mornings, the Pennsylvania-bred ridgling by Eskendereya is progressing nicely for Baffert who won last year’s San Felipe with Dortmund, who provided him with his record fifth San Felipe win. Owned by Michael L. Petersen, Mor Spirit has been ridden to all three of his career wins by Gary Stevens, who’s back aboard on Saturday. – UNCLE LINO: A sharp second in his first route try to Mor Spirit in the 1 1/16 miles Robert B. Lewis, this improving son of Uncle Mo will try to establish himself as a top tier Derby hopeful for trainer Gary Sherlock. Ridden in all four of his starts by Fernando Perez, Uncle Lino pressed a solid pace in the Lewis and finished well. Owned by Tom Mansor, Purple Shamrock Racing or Sherlock, Uncle Lino will get an “acid test” in the San Felipe.   EXAGGERATOR: A big second to undefeated Eclipse Champion Nyquist in Santa Anita’s Grade II, seven furlong San Vicente Stakes Feb. 15, this Kentucky-bred colt by Curlin figures to improve with the added distance and a recent race under his belt. Owned by Big Chief Racing, LLC, Head of Plains, LLC, Rocker O Ranch LLC and Keith Desormeaux, he’s proven to be a versatile sort who can press the pace or stalk. With a pair of graded stakes wins to his credit, he has three overall wins and two seconds from seven starts, good for career earnings of $1,023,120. He’ll again be ridden by Desormeaux’s Hall of Fame brother, Kent.

DERBY QUALIFYING POINTS AT STAKEcenter_img SMOKEY IMAGE: Much like California Chrome in 2014, undefeated California-bred Smokey Image will be trying graded stakes completion for the first time following a massive 8 ½ length win versus statebreds in the California Cup Derby at 1 1/16 miles on Jan. 30. Untouched in six starts, his last three versus Cal-breds, the chestnut colt by Southern Image tried two turns for the first time in the California Cup Derby Jan. 30, winning by 8 ½ lengths in gate to wire fashion. Trained by Carla Gaines, he’ll be ridden by California Chrome’s regular pilot, Victor Espinoza. Smokey Image is owned by Irvin Racing Stable and he’s banked $435,100. DANZING CANDY: Trained by Cliff Sise, Danzing Candy has been ultra impressive in a pair of allowance wins at the current Winter Meet, his most recent a 5 ¾ length gate to wire romp going a flat mile here on Feb. 4. Lightly raced, this Kentucky-bred colt by Twirling Candy will make his stakes debut in the San Felipe, which will be his fourth career start and second around two turns. Bred by Ted Aroney’s Halo Farms and owned by Halo Farms, Bashor or Bashor, Danzing Candy has trained forwardly out of his most recent win and will be ridden for the third time in a row by Mike Smith.THE SAN FELIPE STAKES FIELD IN POST POSITION ORDERRace 7                   Approximate post time, 3:05 p.m. PTUncle – Lino Fernando Perez – 120Danzing Candy – Mike Smith – 120Mor Spirit – Gary Stevens – 124Cupid – Martin Garcia – 120I Will Score – Rafael Bejarano – 120Smokey Image – Victor Espinoza – 120Exaggerator – Kent Desormeaux – 122                The San Felipe Stakes, final major steppingstone to the Grade I, $1 million Santa Anita Derby on April 9, will award the winner 50 Kentucky Derby qualifying points.

GLENTIES DECLARES ITSELF A ‘POSTER-FREE’ ZONE FOR GENERAL ELECTION

first_imgGlentiesGlenties has declared itself a ‘poster-free’ zone for the forthcoming general election.Members if the town’s Community Development Group are asking each candidate not to erect posters in the town i.e within the 50kph speed limits of the town.The group says Glenties has a proud tradition as a tidy town and each year countless hours of hard work and endeavour, not to mention a lot of money, goes into keeping the town looking in the best possible condition all year round. The committee says they feel that the erecting of election posters is an unsightly practice particularly in a town such as Glenties with its ornate street fixings and floral displays.“In previous elections we have regrettably noticed that posters have not been taken down within the allotted time and some left to fall down and lie in ditches whilst the eternal problem of discarded cable ties meant lots of sweeping for the towns hard working volunteers.“We feel that this is a reasonable request given the hard work that goes into keeping Glenties looking as wonderful as it does all through the year.“We trust that you will respect our request and again we wish you all every success and look forward to working with you all for the betterment of Glenties and its environs in the near future,” said Richard Quigley, secretary of the GCDG. Residents in Dungloe have also declared their town a sported-free zone for the elections.  GLENTIES DECLARES ITSELF A ‘POSTER-FREE’ ZONE FOR GENERAL ELECTION was last modified: February 6th, 2016 by StephenShare this:Click to share on Facebook (Opens in new window)Click to share on Twitter (Opens in new window)Click to share on LinkedIn (Opens in new window)Click to share on Reddit (Opens in new window)Click to share on Pocket (Opens in new window)Click to share on Telegram (Opens in new window)Click to share on WhatsApp (Opens in new window)Click to share on Skype (Opens in new window)Click to print (Opens in new window) Tags:donegalelectionGlentiesposterslast_img read more

MLB notes: Trammell out for Tigers; Leyland in?

Early Large Spiral Galaxy Resembles Milky Way

first_imgAstronomers using adaptive optics at the Very Large Telescope (VLT) in Paranal, Chile took spectra of a galaxy at red-shift 2.38 described as an “early young galaxy” that must have, according to current theory, formed very rapidly, because it looks like the Milky Way.  The observations by Genzel et al., published in Nature,1 were described by Robert C. Kennicutt (editor of Astrophysical Journal) in the same issue of Nature2 this way:On page 786 of this issue1, Genzel et al. present remarkable observations of what appears to be a newly formed spiral galaxy, observed when the Universe was just a fifth of its current age.  The result is doubly significant: first, it provides the most detailed glimpse so far of the formation of a galaxy similar to our own Milky Way; second, it demonstrates the power of a new generation of high-resolution instruments that use adaptive optics to study the information and evolution of far-off galaxies.Though Kennicutt claims that our growing catalog of deep-space observations have given rise to “a self-consistent picture of the evolution of galaxies,” he did find it remarkable that such a distant galaxy would look so familiar:The authors’ observations of BzK-15504 reveal it to be a giant spiral galaxy, with a size and mass similar to that of the Milky Way, but observed just 3 billion years after the Big Bang.  It shows many similarities to present-day spiral galaxies, with rotational properties that, again, are nearly identical to those of the Milky Way.  These similarities are notable because they imply that at least some large disk galaxies were broadly in place even at these early cosmic epochs.He says that the spectra imply a rapid burst of star formation in this galaxy 50 times greater than that assumed in our own.  The authors of the paper, after stating the “framework” of galaxy evolution, admitted to some anomalies in the picture:It remains unclear, however, over what timescales galaxies were assembled and when and how bulges and disks—the primary components of present-day galaxies—were formed.  It is also puzzling that the most massive galaxies were more abundant and were forming stars more rapidly at early epochs than expected from models.Everyone thought large spiral galaxies formed late in the evolution of the cosmos.  Kennicut said, “large spiral galaxies with well-developed disks similar to the Milky Way are conspicuously absent in both observations and models of the early Universe.  These large spirals are expected to form rather late, so one would not expect to find many of them at early times,” he added.  But why there are any galaxies this large and mature at such an early age?  “Both these and other results from the same programme are challenging theorists to account for the existence of such massive and well-formed galaxies at such early cosmic epochs, he added, changing the subject to the promise of adaptive optics to answer that question.1Genzel et al., “The rapid formation of a large rotating disk galaxy three billion years after the Big Bang,” Nature 442, 786-789(17 August 2006) | doi:10.1038/nature05052; Received 25 April 2006; Accepted 6 July 2006.2Robert C. Kennicutt, Jr., “Astronomy: Young spirals get older,” Nature 442, 753-754(17 August 2006) | doi:10.1038/442753a; Published online 16 August 2006.The juxtaposition of cockiness about their models and head-scratching about the particulars is what is puzzling.  To keep the model together, they have to have this galaxy, which is surely representative of billions more, forming stars and evolving so rapidly that it looks mature at one-fifth the assumed age of the universe.  This pattern of early maturity is the Cambrian Explosion of cosmology, also known as the Lumpiness Problem.  The early universe shows much more structure (lumpiness) than expected from a nearly homogeneous expansion of an initially uniform particle soup (uniform, that is, to within one part in a hundred thousandth of a degree temperature of the cosmic background radiation).  Astronomers seem to take their lumps in stride.  Sometimes, however, discretion is the better part of valor.(Visited 9 times, 1 visits today)FacebookTwitterPinterestSave分享0last_img read more

London Olympics: Sania and Paes face daunting challenge

first_imgFinally, the monkey is off the back of the Indian contingent with Gagan Narang winning a bronze medal in the 10m air rifle event.The fact that Narang fired 10.7 with his last shot in the close final to finish third proved that he is a champion.Narang’s medal should come as a boost for the rest of the Indian athletes who would be pumped up in the coming days.Coming to tennis, the mixed doubles draw is out and Paes and Sania Mirza will have their task cut out as they face Serbian Ana Ivanovic and Nenad Zimonjic.Zimonjic is a good doubles player but lacks consistency and the Indians would hope that he has a bad day.It was heartening to see that both our doubles combinations (Mahesh Bhupathi-Rohan Bopanna and Leander Paes-Vishnu Vardhan) won their first round matches.Bhupathi and Bopanna were up against a strong pair from Belarus – Maxi Mirnyi, who is ranked no.1, and Alexander Bury.There were no breaks of serve until the 13th game of the deciding set when Bhupathi made two impressive returns. Bopanna then did well to serve out the match.However, it was disappointing to see them go down in straight sets to Frenchmen Julien Benneteau and Richard Gasquet in the second round.It was also an impressive performance by Paes and Vishnu considering that the latter was playing his first match at this level. They were up against the scratch Dutch combination of Robin Haase and Jean-Julien Rojer, who came together for the Olympics.advertisementVishnu lost in the singles, but that experience helped him prepare for the doubles encounter. He could get used to the conditions, the surface and the crowd which would have taken care of the nervous energy of playing in his maiden Olympics.They have a tough prequarter-final against Frenchmen Jo-Wilfried Tsonga and Michael Llodra, both of whom are accomplished doubles players.(The writer is the Fed Cup coach and former player)last_img read more
