The NHL’s “loser point” is the stupidest rule in sports. For the non-puckheads among you, here’s how it works: The NHL awards one point in the standings to a team that loses a game in overtime or a shootout. But teams get two points for winning a game, whether in regulation or beyond. You don’t need a degree in #fancystats to recognize the problem: There are a total of three points to distribute when a game goes to overtime but just two otherwise. So it really pays off to play for OT. As FiveThirtyEight contributors Noah Davis and Michael Lopez documented Wednesday, this encourages dull, passive hockey. Goal scoring falls dramatically in the third period of tied games, right when a game should be coming to its climax.This is more than a minor annoyance; the loser point has already changed the identity of at least one NHL champion. In 2012, the Los Angeles Kings finished with 40 wins and 42 losses; they made the playoffs ahead of the 42-40 Dallas Stars because they accumulated 15 loser points to the Stars’ five. Then the Kings went on to win the Stanley Cup.Fortunately, having a rule as dumb as the loser point means that almost anything would be an improvement. For instance, the NHL could award three points for a win in regulation. An overtime or shootout winner would still get two points. That would at least make each game worth the same amount in the standings.Or you could eliminate the shootout and go back to having ties. The NHL claims that 70 percent to 80 percent of its fans like the shootout but has never made any detailed data on this available to the public. As regular readers of FiveThirtyEight will know, there are lots of ways to manipulate survey questions to produce a desired outcome. Maybe the same consultants telling Donald Trump that he’d make a great presidential candidate are advising Gary Bettman on the loser point.But I have something more radical in mind. Here’s the idea: You keep playing hockey until someone wins. You know, like in the NBA and Major League Baseball and pretty much every other sport but soccer — and like the NHL itself during the playoffs.The usual objection is that this could lead to some extraordinarily long games for two measly points in the standings. What if the Flyers and Penguins play a five-overtime game and the Penguins need to catch a flight to Calgary? Why add even more ice time to a grueling, 82-game regular season?But these cases are rarer than you might think. If you played every NHL regular-season game under playoff rules — 5-on-5 overtime, indefinitely, until someone scores — it would increase ice time by only about 3 percent. In the chart below, I’ve tracked what percentage of overtime playoff games (since 1995) were resolved within a given number of minutes. In the majority of games — 56 percent — someone scored within the first 10 minutes. Only 7 percent of games, meanwhile, required two or more overtimes.Overall, the average overtime game required 13.6 minutes before someone scored. Since 23 percent of playoff games went to OT, that makes the average length of a playoff game about 63 minutes, as compared to around 61 minutes during the regular season.That’s not much of an increase, and if the NHL were concerned about it, it could counteract it by reducing the regular season to 80 games from 82. Then you’d have no shootouts, no ties, no loser point and no overall increase in ice time.Still, maybe we’re concerned about those cases when one team has played a multiple-overtime game and faces off against another on fresh skates. Equivalent cases come up all the time in other sports — baseball, basketball, tennis — and they deal with it. But you could argue that it’s a bigger problem in hockey given the punishing nature of the sport.The solution is to take players off the ice, which will increase scoring. This isn’t a new idea at all — during the regular season, the NHL plays 4-on-4 hockey in overtime, and there have been proposals to go to 3-on-3.But here’s my insight: Goals are scored so quickly during 3-on-3 play that you could play every game to sudden death and pretty much never inconvenience anyone. The players, the referees, the 13-year-old in Winnipeg who refuses to do his algebra homework until the Jets game is finished — they’d all be OK.You may have noticed, in the graphic above, that I drew a smooth curve (labeled “model”) alongside the historical data. The curve is formed by assuming that there’s a 7.4 percent chance of scoring a goal per minute of overtime play, which is the historical rate in the playoffs since 1995. As you can see, the curve “fits” the historical data extremely well. That means the length of overtime games is easy to model.1It also implies that the rate of scoring is fairly constant throughout overtime. If you know the overall rate of scoring, you can accurately guess how many games will require at least two overtimes, for instance.In 4-on-4 play, there’s a 9.1 percent chance of a goal being scored each minute (according to research by Stephen Pettigrew), about 20 percent higher than under 5-on-5 conditions. It’s 3-on-3 action that sees a really radical shift, however, with a 16.8 percent chance of a goal each minute.So what if overtime was played 3-on-3? About 60 percent of games would be resolved within the first five minutes, and 84 percent within the first 10 minutes. Only about 3 percent of overtime games would require double overtime, and fewer than 1 in 1000 would go to triple-OT. The average overtime game would require just six minutes to complete, barely longer than under the current rules.2And you’d reduce the number of overtime games since the loser point would be eliminated — teams would no longer have an incentive to play for OT. And with just three skaters on the ice at a time, teams could give their bench plenty of rest between shifts.The NHL could also adopt some compromise or another. It could play five minutes of 4-on-4 overtime immediately at the end of regulation, as it does now, then clean the ice3During the regular season, the NHL doesn’t bring the Zamboni out and clean the ice after regulation, something you’d probably need to do if you’re going to play more than a few minutes worth of extra hockey. As a fan, I don’t get why the NHL seems to be in a rush to finish overtime games during the regular season — I love the tension that builds up during the pre-overtime intermission in the playoffs. and play an indefinite amount of 3-on-3 overtime if needed. It could declare a tie if no one had scored after a full 20-minute period of 3-on-3 overtime. (Ties would be a rarity, almost like they are now in the NFL.) It could keep removing players from the ice until it was just goalie versus goalie.4The NHL would need to relax the rule that prohibits goalies from advancing past the red line. Would you not stop whatever you were doing to watch Henrik Lundqvist versus Tuukka Rask, one-on-one?Or insert your own proposal: Overtime decided by rock-paper-scissors? Nearly anything would be better than the loser point.
Cleveland Browns2014 Record: 7-9 | 2015 Proj. W: 6.2 | Playoff Odds: 9.7%Off. Rank: 31st | Def. Rank: 11th | S.T. Rank: 14thAs usual, the Browns’ quarterback situation is dismal. Backup Johnny Manziel gets most of the headlines despite (or, perhaps, because of) a spectacularly trying rookie campaign, but new starter Josh McCown isn’t much better. The 36-year-old journeyman showed unexpected flashes of brilliance in eight games as a Bear in 2013, but he returned to form — ranking second-worst in the NFL in QBR — with the Buccaneers last season. Judging from the rest of his career, it would be unrealistic to expect much more from McCown in 2015.We all know that the NFL is a passing league, so Cleveland’s QB predicament puts them at a disadvantage. But if there’s any good news for the Browns, it’s that you don’t necessarily need a great passing attack to build a winning team. And with McCown and Manziel unlikely to lead the Browns out of the quarterback wilderness, it falls upon the team’s defense to provide an edge instead.The Browns return nine starters from what was an effective, and unusual, defense in 2014. Typically, defenses that limit opponents’ passing also have an edge against the running game, and Cleveland was excellent versus the pass — it was third-best in EPA allowed on passing plays, trailing only the Texans and Bills. But the Browns had trouble slowing down opposing runners. Against rushing plays, they ranked 31st in EPA allowed, ahead of only the Saints.Again, the NFL is a passing league, so Cleveland had a top-10 defense despite its weakness against the run. But given the Browns’ lack of offensive playmakers,12Their most important offensive player might be a center. In the five starts Alex Mack made in 2014 before suffering a season-ending injury, the Browns averaged 26 points and a 75 QBR; over the remainder of the season, they averaged 16 points and a 25 QBR. their defense can’t afford to have any vulnerabilities if they hope to win games. That’s why Cleveland drafted nose tackle Danny Shelton 12th overall and added defensive lineman Randy Starks in free agency, with an eye on getting tougher against the run and building an elite all-around defense.It’s an unconventional formula for team-building, but a roster engineered to keep the score low and close can make for upsets. Just last year, the Buffalo Bills used a similar blueprint to win nine games despite having the league’s fifth-worst offense. So if the Browns defense is better than their offense is bad, and they get a few lucky bounces of the ball on special teams, Cleveland might have a winner for just the third time since the franchise was reborn in 1999. Baltimore Ravens2014 Record: 10-6 | 2015 Projected Wins: 9.0 | Playoff Odds: 54.7%Offensive Rank: 15th | Defensive Rank: 5th | Special Teams Rank: 2ndA slight favorite in the AFC North according to ESPN’s preseason Football Power Index (FPI) ratings, Baltimore is more likely than not to make its seventh playoff appearance since 2008. In part, that’s because general manager Ozzie Newsome is playing his own brand of Moneyball. One of his favorite strategies: using free agency to build depth and plug roster holes, rather than trying to sign big-name players at a premium. It’s an approach that keeps the Ravens out of boom-and-bust rebuilding cycles, and keeps generating tickets to the Plinko game that is the NFL playoffs.For instance, Baltimore needed to address its weakness at secondary this offseason. Although the Ravens were tough against the run1They allowed the NFL’s third-fewest rushing expected points. and consistently put pressure on opposing QBs, they also allowed the league’s 10th-most expected points added (EPA) through the air because injuries forced them to field a handful of scrap-heap defensive backs. So Newsome added cornerback Kyle Arrington and safety Kendrick Lewis in free agency to bolster the secondary — moves he could afford to make because of cap room freed up by trading defensive tackle Haloti Ngata for draft picks. The deft deal-making2Along with the return of cornerback Jimmy Smith from injury. is a big reason experts think Baltimore will reclaim elite-defense status this season.Another signature Newsome move was to let free-agent wide receiver Torrey Smith walk, rather than paying the $22 million sticker price he was eventually guaranteed by San Francisco. While other teams shell out for expensive free-agent receivers such as Smith, Vincent Jackson and Mike Wallace, Newsome has had success with cheaper options. Take Steve Smith, whom the Ravens were able to sign on the cheap3Paying only an average of $3.5 million per season. a year ago because of his advancing age (he was 35 last season). All Smith did in his Baltimore debut was produce one of the top receiving seasons in Ravens history — and help quarterback Joe Flacco post the best Total Quarterback Rating (QBR) of his career.Even running back Justin Forsett, whose breakout season lifted Baltimore’s yards per carry from last in the league in 2013 to a tie for sixth last season, was paid only $730,000 a year ago — a pittance by RB standards. Forsett got a raise for 2015 but should benefit from another secret weapon smart teams often use: continuity. All five starters on the Ravens’ offensive line are also returning, and incoming offensive coordinator Marc Trestman is expected to keep predecessor Gary Kubiak’s running scheme.Newsome appears to recognize a few fundamental truths about the NFL: namely, that bank-breaking offseason pickups are rarely worth the trouble and that teams are better off using their money to build depth and bolster multiple positions. It’s a formula that has served the Ravens well over the years and should continue to pay off in 2015.

Check out our coverage of every division » Cincinnati Bengals2014 Record: 10-5-1 | 2015 Proj. W: 8.4 | Playoff Odds: 42.1%Off. Rank: 14th | Def. Rank: 12th | S.T. Rank: 8thFPI predicts that the Bengals will be solid again in 2015, and one of the primary reasons is continuity. Twenty-one of their 22 starters are back from a year ago, which ties for the second-most returning starters any NFL team has carried into a season since 2006. Plus, prodigal defensive end Michael Johnson returns after a season in Tampa Bay, and linebacker Vontaze Burfict might (eventually) come back from the knee injury that cost him most of 2014.While researching FPI,4I was on the production analytics team that developed FPI this summer. we found that consistency like this, especially when the team is already decent — as the Bengals were last year — is a small but reliable predictor of success. And in the absence of a first-class quarterback, Cincinnati needs all of these small things to go its way if the team wants to stay competitive.Bengals starting quarterback Andy Dalton has a lifetime QBR of 51, which pretty much makes him the definition of average. (QBR is scaled where the league-wide mean is 50.) Fans and observers have spent years wondering if Dalton can become a top passer, but four seasons of consistently middling numbers probably suggest that we’ve seen his best. He’s dependable, and even good enough to make a winner out of a team if it surrounds him with talent. But rarely do quarterbacks blossom into something new after four full seasons in the NFL.So instead of counting on Dalton to be great, Cincinnati has built a balanced roster that doesn’t need a star turn at QB. Wideout A.J. Green, for instance, picks up the slack by serving as Dalton’s target more than 30 percent of the time, one of the highest shares for any receiver in the league. Although Dalton played well enough to win two of the three games Green missed last season, it would be unwise to think the Bengals offense would prosper for long without Green’s ability to stretch defenses downfield.And defensively, FPI projects the Bengals to bounce back after a down year in 2014. Cincy’s defense had allowed the NFL’s second-fewest overall EPA and fifth-lowest rate of yards per attempt two years ago, but they fell to 16th and 20th, respectively, after the departure of defensive coordinator Mike Zimmer a year ago. Losing a coordinator can be surprisingly traumatic for a defense (more on this later), so they should be better in Paul Guenther’s second season at the helm.Continuity, on both the roster and coaching staff, is one of several small factors Cincinnati will have to rely on this season. Because unless, by some miracle, Dalton turns into a top passer, the Bengals need all the advantages they can get. In preparation for the 2015 NFL season, FiveThirtyEight is running a series of eight division previews, each highlighting the numbers that may influence a team’s performance (including projections and rankings based on ESPN’s preseason Football Power Index). Today we focus on the AFC North, where Baltimore, Cincinnati and Pittsburgh have all taken the division title twice over the past six seasons. Will the defending-champ Steelers hand it off again this year? And can the Browns finally break into that group? Pittsburgh Steelers2014 Record: 11-5 | 2015 Proj. W: 8.3 | Playoff Odds: 41.4%Off. Rank: 9th | Def. Rank: 24th | S.T. Rank: 4thThe Steelers had a very un-Steeler-like team in 2014. The offense was white-hot: Antonio Brown led all NFL receivers in fantasy scoring5Using ESPN’s standard scoring system. by a wide margin, Le’Veon Bell finished second among running backs, and Ben Roethlisberger ranked fifth among quarterbacks.6Even Heath Miller ranked 11th among tight ends despite seeing the fourth-lowest target frequency of any qualifier at his position. The defense, on the other hand, was full of holes, as age7They were one of the oldest defenses in the league. and free agency8They lost a number of veterans, including Larry Foote, LaMarr Woodley and Ryan Clark. caused a unit once nicknamed the “Steel Curtain” to allow the league’s third-worst rate of yards per play.Pittsburgh still used that bizarro-world formula to squeak past its rivals for the division crown. But it doesn’t bode well as a blueprint for sustainable winning, because there are reasons to think the defense won’t rebound even as the offense falls back to earth.By virtue of regression to the mean, we usually expect defenses to bounce back from uncharacteristically bad seasons, but Pittsburgh’s situation is complicated by the departure of legendary defensive coordinator Dick LeBeau. When developing FPI, we found that defensive coordinators have a similar (albeit smaller) impact on defense as quarterbacks do on offense — namely, that when a team has a returning coordinator, its defensive performance tends to be better and more consistent between seasons. Conversely, when a new coordinator comes in, the defense usually declines a bit9Regardless of its previous quality. and generally is harder to project.10In statistical speak, the variance is higher in projections involving new defensive coordinators. So it’s difficult to say whether the 2015 Steelers will be any better defensively than the 2014 team.And Pittsburgh might not be able to afford another down defensive year. Although the Steeler offense was surprisingly strong in 2014, it’s probably not realistic to expect a repeat performance — most obviously because Bell will be suspended for the season’s first two games, but also because the team is unlikely to be as healthy as it was last season. Not only was Pittsburgh’s offensive “injury score”11A weighted total of players designated as “out,” “doubtful” or “questionable” by the NFL’s official weekly injury reports. the lowest of any team a year ago, but the team also lost less than half as much playing time to injury as the average NFL offense from the past nine years. It’s highly unlikely that they’ll be so fortunate again.This doesn’t necessarily mean Pittsburgh needs a complete rebirth of the Steel Curtain defense. (The FPI projections still point to the Steelers being a top-10 team, after all.) But with Baltimore and Cincinnati each boasting a slightly higher probability of winning the division, the defense probably has to improve if the Steelers want to repeat as AFC North champs.
The Cincinnati Bengals signed former Buckeye kicker Aaron Pettrey on Tuesday afternoon. Pettrey will replace Mike Nugent, another former Buckeye kicker. On Monday, Pettrey was excited about trying out for the Bengals. On Tuesday, he made the roster of the team he grew up rooting for. “It’s pretty cool,” Pettrey said. “My dad is excited. My family is already looking for tickets.” Pettrey’s signing came on the heels of Nugent’s season-ending knee injury. Nugent won AFC Player of the Month for September but struggled in November, missing two of three field goal attempts in two games. “It’s bittersweet,” Pettrey said. “It’s nice being here, but I’d like to see Mike keep kicking this year. Under the circumstances, I wish it were a different route.” Nugent was upset about his injury but happy for Pettrey’s opportunity. “He’s a really good guy,” Nugent said, “works really hard and is the kind of person Coach (Jim) Tressel likes to bring in. He’s one of those people that makes you look at your character and how hardworking you can be.” Pettrey recovered from an MCL tear that kept him sidelined for three games in OSU’s 2009 season. Devin Barclay took over Pettrey’s kicking duties while he was injured. “I learned a lot from him,” Barclay said. “He’s a tough kid. Mentally strong, a great leg, kind of a guy who leads by example. Just a class act all-around.” Pettrey played multiple positions in high school but knew kicking is what would take him to the highest level. “That’s what I really wanted to do,” Pettrey said. “Kicking and eventually making it to the NFL, at the highest level.”

Source:https://www.bcm.edu/ Reviewed by James Ives, M.Psych. (Editor)Nov 28 2018Using a multidisciplinary approach, an international team of researchers from several institutions, including Baylor College of Medicine, reveals that complex interactions between sugars and the microbiome in human milk influence neonatal rotavirus infection. Reported in the journal Nature Communications, this study provides new understanding of rotavirus infections in newborns and identifies maternal components that could improve the performance of live, attenuated rotavirus vaccines.”Rotavirus infection causes diarrhea and vomiting primarily in children younger than 5, with the exception of babies younger than 28 days of age, who usually have no symptoms. However, in some places, infections in newborns are associated with severe gastrointestinal problems. What factors mediate differences between newborns with and without symptoms are not clearly understood,” said first and corresponding author Dr. Sasirekha Ramani, assistant professor of molecular virology and microbiology at Baylor College of Medicine. “We began our investigation years ago by determining that a particular strain of rotavirus was associated with both asymptomatic infections and clinical symptoms in newborns.”Ramani and her colleagues first looked for answers from the perspective of the virus. They investigated whether factors such as the amount of virus in newborns or the genome of the virus could be linked to the presence of symptoms in newborns, but did not find any connection between those factors. The researchers then posed the question from the perspective of the newborn. Are there factors in newborns that could explain why this virus infects neonates and why there are differences in clinical presentation?In the lab, the researchers investigated whether components of the mother’s breast milk could inhibit infection of MA104 cells, a well-established model for rotavirus studies, with the particular strain of rotavirus they had identified in the neonatal nurseries in India. Unexpectedly, they discovered that specific sugars present in mother’s milk enhanced infection of cells in culture with the neonatal rotavirus strain.”We were surprised by these results,” Ramani said. “Breast milk is known to enhance newborn protection against rotavirus infection and sugars in breast milk can reduce infectivity of other rotaviruses, but here we found the opposite for this particular strain of the virus.”The researchers then went back to the field to determine whether they could validate the results they had found in the lab in a cohort of mother-infant pairs.Related StoriesGrowth problems in preterm infants associated with altered gut bacteria‘Stomach flu’ vaccine prevents type 1 diabetes in childrenGut-boosting food may put an end to childhood malnutrition worldwide”We found that some of the same specific sugars in breast milk that increase infectivity of cells in culture are present in the milk of mothers of newborns with symptomatic infection,” Ramani said.In addition, the researchers found an association between the microbiome in the mothers’ milk and gastrointestinal symptoms in newborns, which prompted new questions, Ramani explained. How does the microbiome contribute to the differences in gastrointestinal symptoms?”What is most interesting to us is that these sugars also increase the replication of the rotavirus attenuated, live vaccine that is similar to the neonatal virus that we are studying,” Ramani said. “Enhanced viral replication can potentially translate into a more effective immune response against the virus, which would lead to better protection for the infant. This is something we want to explore in the future because it could illuminate strategies to improve the effectiveness of rotavirus vaccines in parts of the world where they do not do well.””One of the most important things to us is that these unexpected findings are tightly linked to public health,” said co-author Dr. Mary K. Estes, Cullen Foundation Endowed Professor Chair of Human and Molecular Virology at Baylor College of Medicine and emeritus founding director of the Texas Medical Center Digestive Diseases Center. “The multidisciplinary nature of our team of researchers has allowed us to answer questions about how this unique rotavirus strain infects neonates, confirm the findings in the field and open possibilities to improve the effectiveness of rotavirus vaccines where they are needed the most.””These discoveries are a prime example of the urgent need to improve our understanding of the composition and variation in breast milk components,” said co-author Dr. Lars Bode, associate professor of pediatrics and director and chair of Collaborative Human Milk Research at the Larsson-Rosenquist Foundation Mother-Milk-Infant Center of Research Excellence at the University of California, San Diego. “Understanding how rotavirus and other pathogens can take advantage of breast milk components will guide the development of new vaccination strategies to stay ahead in the host-pathogen arms race.”
FACT BOX: Register-based research and personal data in Denmark Source:University of Copenhagen It is surprising, that the effect of a concussion has such severe consequences for this group of people and their ability to maintain a normal job even five years after the trauma. Long-term symptoms like fatigue and difficulties in concentrating can of course afflict anyone regardless of their level of education. What stands out is that those with a higher education are in such higher risk of losing their job. It could be due to the fact, that they often hold jobs where they plan and prioritize their tasks and the workload by themselves, and that the mental surplus and overview required to do so are some of the skills that are often severely impaired in the aftermath of a concussion.”Hana Malá Rytter, Associate Professor in Neuropsychology, University of Copenhagen and Head of the Danish Concussion Center Via registers of i.e. Statistics Denmark and the National Board of Health, researchers can follow a person’s life on a number of parameters. Information on citizens’ health, work, education, marital status, housing etc. is collected and stored in these records. Researchers in register-based research can apply for access to the data they are interested in, if they are able to argue why they should have access to the desired information. They are only allowed access to depersonalized information so that citizens’ personal data is kept protected. This means that researchers can follow groups of individuals’ data, for example linking information about health and annual income, but they cannot see the identity of the individual person. The researchers do not have permission to look for or report statistics that can identify individuals, and there are extra strict requirements regarding particularly sensitive data such as health data. The large data files are physically located on Statistics Denmark’s secure servers, so no data is stored locally with the researchers. Not able to do the sameEven though it might sound like a great advantage to be able to plan your workday yourself whilst recovering from a head trauma, it is in fact often an advantage for these patients, if someone else takes charge and hands out simple, well defined job tasks to be completed one at a time. This may be one of the reasons, why researchers find that people with low education levels are better able to keep their job.-People with higher education often hold positions, where they are required to multi-task, engage in teamwork and shift focus between different tasks while making decisions and taking responsibility. Skills that are often challenged, when long-term symptoms after concussion impair the ability to concentrate. Our data indicate that part of these patients must face that they simply are not able to do the same, as they used to before, says Hana Malá Rytter.The study is the first register data-based study that analyses patients’ labor market activity up to five years after a concussion, and it is the first study to reveal what specific groups of patients are affected the most in terms of their employment status in the aftermath of a concussion.Worst for the 30-somethingsThe researchers also identified another specific group of patients that were markedly more at risk of leaving the labour market following a concussion: People between the ages of 30-39. Data showed that their risk of having left a regular job five years after a concussion was twice as high, compared to people of the same age in the control group without concussion. According to Hana Malá Rytter, this may have to do with the life situation in which people in their thirties often find themselves.- Men and women in their thirties have often completed their education a few years earlier and are just establishing themselves in their professional life and as a family too. In this phase of life, people often make high demands on themselves both in and outside their workplaces. Moreover, becoming parents is a challenging and stressful process for young families. Expectations regarding the capacity of the individual are often towering – both from employers, colleagues, family members and from the individuals themselves. So once they are struck by long-term consequences of a concussion that often reduce their mental surplus and their ability to focus. Their whole life situation suffers so much harder, than if this happened later in life. And this seems to make some of them give up on their job, explains Hana Malá Rytter.Related StoriesResearch team to create new technology for tackling concussionNeural pathways explain the relationship between imagination and willingness to helpPosterior parietal cortex plays crucial role in making decisions, research showsFor people in their forties, the risk of losing a job following a concussion is raised approximately 30% compared to peers without concussion, while the researchers hardly saw any increase in people leaving the workforce following a concussion in the group of 50-59-year-olds.- Senior professionals may have a more relaxed attitude to what they are supposed to accomplish in life in general and in their professional career in particular. From other studies we also know that it is easier to adjust to a long-lasting disease, if this happens later in life, says Hana Malá Rytter.Better advice for patientsAccording to Hana Malá Rytter, patients should receive better and more precise advice from both doctors, nurses and other professionals in the health and social care system following a concussion. It is important that the patients’ entire life situation is taken in to account.Patients with concussion rarely receive actual treatment, as the brain primarily needs time and rest in order to heal. In general, patients are advised to merely go home and take it easy for a few weeks – and to pay attention to what level of activity they feel they are able to handle. And that can create a false expectation that they are soon back in business.- It differs greatly how much activity people expect of themselves, and health professionals need to draw attention to the cognitive and mental limitations that often strike the young professionals and those with higher education in the wake of a concussion. They need to be told, that this may take many weeks or even months, before they can expect to be back at full speed in the way they were prior to the head trauma. If not, they may strain their mental capacities and that can delay the healing of the traumatized brain, explains Hana Malá Rytter and continues:- Furthermore, they may experience defeat, when the exhaustion causes symptoms to worsen again and they have to give up. This can cause stress and we know from other studies that this will delay the healing process.The researchers also identified two other groups that are at particular high risk of losing attachment to the labor market: Patients with chronic diseases (i.e. diabetes, heart- or liver disease or HIV) prior to the concussion, and patients that were of non-Danish origin. This is not surprising, as plenty of research points to the fact that chronic disease in itself has a very negative effect on a person’s perceived life quality. In addition, being part of a minority group is linked to a series of problems that increase the risk of early retirement and receiving disability payment.FACT BOX: Labor market attachment after mild traumatic brain injury the survey is the first register study on patients with concussion, where researchers follow a large number of patients for several years. (2003-2007) 19,732 Danes aged 18-60 years and diagnosed with concussion in hospitals were followed five years after the incident. researchers did not study the patients’ physical symptoms following concussion, but the analyzed on patients’ labor market attachment six months and five years after the concussion respectively to see, if they were in regular work, without work, in reduced-hour jobs or on early retirement. the results are adjusted in terms of gender, age, location in the country, marital status, income, education, ethnicity, and already existing illness. Only persons, who at the beginning of the survey were either working or job seeking, were included in the survey. People who had had previous concussions over the past five years, and people with psychiatric diagnoses were excluded. the control group consisted of 18,640 Danes without concussion. Reviewed by James Ives, M.Psych. (Editor)Jul 10 2019A hard tackle on the football-field, a crash on your bike or a fall from a ladder in your home can easily cause a concussion, which eventually can cost your job – especially if you are in your thirties, and have a higher education.These are some of the findings in a large new register-based data research study from a team of researchers at the University of Copenhagen in Denmark led by PhD student in Public Health, Heidi Graff, and neuropsychologist Hana Malá Rytter from the Department of Psychology.Each year 25,000 people in Denmark are diagnosed in hospitals with concussion (mild traumatic brain injury) that make up roughly 90% of all injuries causing trauma to the head. Although mortality is low, and surgical intervention rarely required, up to 15% of patients suffer from persistent symptoms and functional impairment following the injury, that may have severe personal costs and often make it hard to resume their normal jobs and lives.The Danish study includes all groups of patients and is representative for the general population in Denmark in terms of age, geography, education, family background and marital status.Using register data from 19,732 Danes between the ages of 18 and 60 that were all diagnosed with a concussion, researchers traced the patients’ attachment to the labor market during five years and compared the data to an equally sized control group of people without concussion.They found that people with concussion have a markedly higher risk of being out of a job five years after the trauma. Instead they are unemployed, receiving payments due to disability or early pension or working part-time supported by social benefits.Especially two groups of patients were severely struck by long-term symptoms: Those in their thirties and those with a higher education.Five years of labor market dataThe researchers did not examine the patients physically or screen their medical records to assess the patients´ medical symptoms following the concussion. They merely looked at their labor market data six months and five years after the head trauma respectively. Accordingly, they were surprised to find out that people between the ages of 30-39 and those with a higher education are much more likely to have lost their connection to a normal job following a concussion.While people with low education levels (that is having 9 years of primary education and no other education after that) have a 30% higher risk of leaving the normal labor market following a concussion than people without concussion. The same risk is over 215% for people with higher education (that is having 12 or more years of education, for instance studies at college or university level)

Citation: Intel underfoot: Floor sensors rise as retail data source (2018, January 15) retrieved 18 July 2019 from https://phys.org/news/2018-01-intel-underfoot-floor-sensors-retail.html More businesses are trying mobile apps to lure and keep consumers Online clicks give retailers valuable insight into consumer behavior, but what can they learn from footsteps? It’s a question Milwaukee-based startup Scanalytics is helping businesses explore with floor sensors that track people’s movements.The sensors can also be used in office buildings to reduce energy costs and in nursing homes to determine when someone falls. But retailers make up the majority of Scanalytics’ customers, highlighting one of several efforts brick-and-mortar stores are undertaking to better understand consumer habits and catch up with e-commerce giant Amazon.Physical stores have been at a disadvantage because they “don’t have that granular level of understanding as to where users are entering, what they’re doing, what shelves are not doing well, which aisles are not being visited,” said Brian Sathianathan, co-founder of Iterate.ai, a small Denver-based company that helps businesses find and test technologies from startups worldwide.But it’s become easier for stores to track customers in recent years. With Wi-Fi—among the earliest available options—businesses can follow people when they connect to a store’s internet. One drawback is that not everyone logs on so the sample size is smaller. Another is that it’s not possible to tell whether someone is inches or feet away from a product.Sunglass Hut and fragrance maker Jo Malone use laser and motion sensors to tell when a product is picked up but not bought, and make recommendations for similar items on an interactive display. Companies such as Toronto-based Vendlytics and San Francisco-based Prism use artificial intelligence with video cameras to analyze body motions. That can allow stores to deliver customized coupons to shoppers in real time on a digital shelf or on their cellphones, said Jon Nordmark, CEO of Iterate.ai.With Scanalytics, Nordmark said, “to have (the sensors) be super useful for someone like a retailer, they may need to power other types of things,” like sending coupons to customers.Scanalytics co-founder and CEO Joe Scanlin said that’s what his floor sensors are designed to do. For instance, the sensors read a customer’s unique foot compressions to track that person’s path to a digital display and how long the person stand in front of it before walking away, he said. Based on data collected over time, the floor sensors can tell a retailer the best time to offer a coupon or change the display before the customer loses interest. The next phase in data collection is right under your feet.

He employs about 20 people.Wisconsin-based bicycle retailer Wheel and Sprocket uses Scanalytics’ sensors—which can be tucked under utility mats—to count the number of customers entering each of its eight stores to help schedule staff. © 2018 The Associated Press.

The sensors are among the tools retailers are using to gain insights on consumer habits. (AP Photo/Ivan Moreno) “That’s our biggest variable expense,” said co-owner Noel Kegel. “That sort of makes or breaks our profitability.”Kegel wants to eventually have sensors in more areas throughout his stores to measure where customers spend most of their time and what products are popular, but he said it’s too expensive right now.The cost of having the sensors ranges from $20 to $1,000 per month, depending on square footage and add-on applications to analyze data or interact with digital signs, Scanlin said. He said he’s working with 150 customers in the U.S. and other countries and estimates that about 60 percent are retailers.The emergence of tracking technologies is bound to raise concerns about privacy and surveillance. But Scanlin noted his sensors don’t collect personally identifying information.Jeffrey Lenon, 47, who was recently shopping at the Shops of Grand Avenue mall in Milwaukee, said he wasn’t bothered by the idea of stores tracking foot traffic and buying habits.”If that’s helping the retailer as far as tracking what sells and what no, I think it’s a good idea,” Lenon said.These technologies have not become ubiquitous in the U.S. yet, but it’s only a matter of time, said Ghose Anindya, a business professor at New York University’s Stern School of Business.”In a couple of years this kind of conversation will be like part and parcel of everyday life. But I don’t think we’re there yet,” he said.——A sampling of tracking technologies for traditional storesBrick-and-mortar retailers are using different tracking technologies to better understand their customers and keep up with e-commerce giant Amazon. Here is a sampling of the different tracking methods available to stores:FLOOR SENSORSPaper-thin tiles developed by Milwaukee-based Scanalytics measure foot compressions to analyze people’s movements over time so stores know what products displays draw customers’ attention and for how long. That allows businesses to study what sells, know when to schedule staff for busy times, and what store layout is most effective. The technology might still be too pricey for smaller retailers, however.INTELLIGENT VIDEO CAMERASCompanies such as Toronto-based Vendlytics and San Francisco-based Prism use artificial intelligence with video cameras to analyze body motions. That can allow stores to deliver customized coupons to shoppers in real-time on a digital shelf or on their cellphones on an app.MOTION SENSORSSunglass Hut and fragrance maker Jo Malone are using laser and motion sensors from Perch Interactive to tell when a product is picked up but not bought. The technology can also make recommendations for similar items on an interactive display.WI-FI BEACONSWi-Fi beacons can track customer movements—as long as they connect to the store’s internet. Because not everyone opts in, stores have a smaller sample size to analyze. Another drawback is that it’s not possible to tell whether a customer is inches or feet from a product.
10 Medical Conditions That Sound Fake but Are Actually Real 27 Oddest Medical Case Reports A man in Gaza with an extremely rare skin condition dubbed “tree man syndrome” says his life has been changed by a pioneering surgical treatment, according to news reports. The man, 44-year-old Mahmoud Taluli, has undergone four surgeries in the last two years to remove extensive, wood-like lesions on his hands, according to NPR. Prior to the surgeries, Taluli hadn’t been able to use his hands for more than a decade. “After years of suffering and solitude, I can finally live a normal life,” Taluli told NPR. “I can play with my children. I can go to family events. I no longer need to cover my hands when I go out in public.”Headbutting Tiny Worms Are Really, Really LoudThis rapid strike produces a loud ‘pop’ comparable to those made by snapping shrimps, one of the most intense biological sounds measured at sea.Your Recommended PlaylistVolume 0%Press shift question mark to access a list of keyboard shortcutsKeyboard Shortcutsplay/pauseincrease volumedecrease volumeseek forwardsseek backwardstoggle captionstoggle fullscreenmute/unmuteseek to %SPACE↑↓→←cfm0-9接下来播放Why Is It ‘Snowing’ Salt in the Dead Sea?01:53 facebook twitter 发邮件 reddit 链接https://www.livescience.com/65907-tree-man-gaza-surgery.html?jwsource=cl已复制直播00:0000:3500:35 Taluli has a rare genetic condition called epidermodysplasia verruciformis, which makes him much more susceptible to skin infections caused by the human papillomavirus (HPV), compared with the average person, according to a 2010 report of the condition published in the journal Disease Markers. People with this condition have immune system problems that prevent them from properly fighting off HPVs — a group of more than 150 related viruses. In healthy people, HPVs often don’t cause symptoms, but in people with epidermodysplasia verruciformis, the infections lead to the formation of wart-like skin lesions, which progress to malignant tumors in about 50% of patients, according to the 2010 report. There is no cure or standard treatment for the condition. Taluli’s treatment has involved doctors making deep incisions into the skin to remove thousands of lesions, NPR reported. This tissue removal often requires skin grafts from other parts of his body to help with healing. The treatment has allowed Taluli to use his hands again, but it is not a cure — new growths continue to show up, and Taluli will need a fifth operation this summer to remove these new lesions, as well as some scar tissue, NPR reported. Still, the treatment has been largely successful in improving Taluli’s hand function. “We didn’t know if there would be anything viable left of his hands, but thank God it’s working,” Dr. Michael Chernofsky, a hand and microvascular surgeon at Hadassah Medical Center in Jerusalem, who treated Taluli, told NPR. Ultimately, doctors hope to develop a treatment that can help Taluli’s immune system better fight HPV, NPR reported. Another man with epidermodysplasia verruciformis hasn’t fared as well. Last month, it was reported that Abul Bajandar of Bangladesh had asked doctors to amputate his hands due to pain from the condition, according to Fox News. Although Bajandar has had more than 20 surgeries to remove skin lesions, the growths appear to be coming back worse than before. Chernofsky told NPR that amputation is usually not a good idea, because the patient would likely still experience pain from severed nerves.
