Fish and Game Traps 3 of Hanover’s Nuisance Bears – Valley News

Hanover Three juvenile bears that were initially targeted to be destroyed after two of them forced their way into a residence and later won a reprieve from Gov. Chris Sununu have been trapped and relocated.

One of the bears was captured on Saturday and two more were trapped on Sunday. All of them were captured using culvert-style bear traps set near dumpsters at Wheelock Terrace and Buck Road, according to Andrew Timmins, the state of New Hampshire Fish and Games Bear Project leader.

All released together today, Timmins said in an email on Memorial Day.

They were set free at an undisclosed location in the North Country, Timmins said, adding each one was tagged to aid in future tracking.

The bears mother hasnt been accompanying the juveniles in recent days, Timmins said, and as of Sunday evening she had not been captured. Fish and Game will resume efforts to trap her this week, he said.

While she may be spending more time out of town during breeding season, she ultimately will return to her core area and likely have her next litter of cubs in January, Timmins said.

Its been suggested the sow might leave the area if attractants, such as food and birdseed, are cleaned up, Timmins said.

But hes doubtful residents in Hanover and Lebanon will comply sufficiently before more cubs are born.

As much publicity as has been on this issue over the past week, I have seen very little improvement on the reduction of food attractants in the area, particularly on the Route 120 side, he said.

This spring, the bear family, fresh from hibernation, became notorious for wandering through a neighborhood between downtown Hanover and Mink Brook, drawn by unsecured household trash and bird feeders left out after the winter.

When two of the bears entered a Thompson Terrace home two weeks ago, Fish and Game officials announced their intent to destroy the bears, saying the animals were too accustomed to humans and were unlikely to be successfully relocated.

But public outcry over plans to euthanize the animals was swift.

More than 10,000 people, many from outside the state, signed an online petition within days to save the bears.

Meanwhile, Ben Kilham, a bear biologist in Lyme who rescues wild bears, questioned whether killing the bears was necessary. Kilham said last week that with black bear breeding season approaching, the sow would soon chase her cubs away so she could mate.

Kilham emphasized that human behavior needed to change in order to change bear behavior.

Gov. Chris Sununu ultimately stepped into the fray late last week and ordered wildlife officials to relocate the bears.

I am glad that we have been able to find a safe and humane option for these bears and I encourage residents to work with their local town officials to enact ordinances that could help avoid situations like this in the future, Sununu said in a prepared statement.

Sununus decision was praised by many, particularly Nicole Cantlin, the Enfield resident who started the online petition to save the animals.

Cantlin was present when two of the cubs were tranquilized on Sunday and posted photos of two sedated bears to her Facebook page on Monday.

I did get to see them awake before these shots and they were more like dogs than a wild animal. Its sad people have made them this way, she wrote. Hoping they can make a new life up north.

UCR researchers explore how the brain communicates fear – Highlander Newspaper

Courtesy of UCR Today

On May 10, Jun-Hyeong Cho, assistant professor of cell biology and neuroscience at UCR, and Woong Bin Kim, a postdoctoral researcher in Chos lab, published their study on fear memory in Journal of Neuroscience. Cho and Kim conducted studies on fear memory to understand how the brain interprets and remembers fear. They concluded that humans and animals develop adaptive fear responses to dangerous situations to survive. In addition, their research focused on the specific areas of the brain that are involved in fear memory.

Their study focused on understanding the mechanistic features of the double-projecting neurons that are sent out from the hippocampus to the amygdala and the medial prefrontal cortex (mPFC). The hippocampus encodes context cues (the set of circumstances around an event), the amygdala stores associations between a context and an aversive event, and the mPFC signals whether a defensive response is appropriate in the present context, Cho explained in an interview with the Highlander.

This study could help researchers learn more about fear-related conditions such as post-traumatic stress disorder (PTSD). According to the U.S. Department of Veterans Affairs, PTSD is a mental health problem that some people develop after experiencing or witnessing a life-threatening event, like combat, a natural disaster, a car accident, or sexual assault. Cho explained that around seven percent of Americans today suffer from PTSD, and this study proposes that it may be caused by a disruption in the natural fear-learning process.

To conduct their research, the pair used a tracing method in the brains of the mice to show the hippocampal neurons that project to different areas in the brain. The neurons are labeled with fluorescent proteins with different colors to show their movements throughout the brain. We also found neural mechanisms (are) how these double-projecting neurons efficiently convey contextual information to the amygdala and mPFC to encode and retrieve fear memory for a context associated with an aversive event, said Cho.

Cho has been an assistant professor in the cell biology and neuroscience department at UCR since 2014. Before coming to UCR, Cho was an instructor in psychiatry at Harvard Medical School from 2012-2014. Cho hopes that his continued research will uncover how the brain works in learning and fear.

Cho says that they want to continue researching about the effects of these neurons on individuals fear memory. To do this, they will selectively silence the neurons and see how it impacts the formation of fear memory. Although the two researchers have published their work so far, they hope to continue research in this field in the future.

Swedish double-booked its surgeries, and the patients didn’t know – The Seattle Times

Some of Swedish Healths top neurosurgeons have routinely run multiple operating rooms at the same time while keeping patients in the dark about the practice, The Seattle Times has found. Swedish touts its patient outcomes and is clarifying its consent forms.

Since her surgery, Phyllis Johnsons neck has been so askew that she can no longer look toward the sky. After his surgery, Duane Pearson found his hands frequently stinging with pain. Orna Berkowitzs surgery was supposed to be routine, but she ended up in the hospital for 41 days.

The three patients had placed their trust in the same doctor, Rod Oskouian, a top neurosurgeon at Swedish Health.

But there was something they didnt know: Oskouians attention was split during each of their procedures, with internal data showing he was running two operating rooms at the same time.

Johnson, Pearson and Berkowitz recently learned about the double-booked cases from a reporter. Each said they likely wouldnt have consented to the surgery if theyd known that was happening.

Those cases, along with many others at Swedish, illustrate the wide gulf between the expectations of Swedish patients and the reality of whats happening in the operating room once they are under anesthesia for perilous procedures. In recent years, some of Swedishs top brain and spine surgeons routinely ran multiple operating rooms at the same time while keeping patients in the dark about the practice, according to internal surgery data obtained by The Seattle Times as well as interviews with patients and medical staffers.

Four surgeons at the Swedish Neuroscience Institute Oskouian, David Newell, Johnny Delashaw and Jens Chapman ran multiple operating rooms during more than half their cases over the past three years, according to the data. Oskouian did it 70 percent of the time. To manage two rooms, surgeons generally leave less-experienced doctors receiving specialized training to handle parts of the surgery.

Swedishs interim CEO, Dr. Guy Hudson, previously said the best way to describe cases involving multiple operating rooms was the word overlapping, suggesting that a second surgery may start as a first one is coming to a close. As evidence, he said Swedishs internal system wont let surgeons schedule cases to start at the same time.

But the data obtained by The Times show a conflicting reality: Between 2014 and 2016, there were more than 200 instances when surgeons began two cases at the same time or within five minutes of each other. When doctors ran multiple operating rooms, they typically overlapped their cases for more than an hour, according to the data. More than 700 of the surgeries were entirely eclipsed by other cases the attending surgeon was handling.

Recent research on overlapping surgeries has drawn inconsistent conclusions about whether it can lead to worse outcomes for patients, and Swedish officials pointed to some of those studies in responding to this story.

Hudson said last week that Swedish is still exploring the outcomes of its own overlapping versus non-overlapping cases, but he cited metrics showing that the institution and its Cherry Hill facility have consistently had better overall outcomes than industry norms. And he said that with rising demand and a training program for fellows, running multiple operating rooms allowed surgeons to treat more patients.

But Hudson said Swedish is working to be more transparent about the issue. Earlier this month, neurosurgeons at Swedishs Cherry Hill facility began testing a new consent form that explicitly mentions the prospect of overlapping surgery.

As a surgeon, I believe trust is the most important attribute between a patient and their doctor, Hudson said. He also said he has learned that his past statement that surgeries could not be scheduled to start at the same time was incorrect.

Oskouian and Newell declined to comment. Chapman did not respond to messages seeking comment. An attorney for Delashaw said he was routinely and appropriately present in each operating room during overlapping surgeries, and he always sought to achieve the best outcome for his patients.

The Times previously reported on a range of internal concerns about patient care at Swedishs neurosurgery unit, where surgical volumes had been surging and contracts incentivized doctors to do large numbers of procedures. The articles examined particular concerns about Delashaw, the institutes top surgeon.

After the initial Times articles, Swedish CEO Tony Armada resigned, as did Delashaw. The state Department of Health and the U.S. Attorneys Office have also launched investigations, without publicly specifying their focus.

The dozen or so surgeons at the Swedish Neuroscience Institute have taken varying approaches to managing their workloads.

Some of the doctors ran simultaneous cases on just a handful of occasions over the past few years. Oskouian, however, had 1,355 overlapping surgeries between 2014 and 2016, and in nearly three-quarters of those cases, the time the patient spent in surgery was mostly eclipsed by another case, according to internal data.

Some doctors typically had only brief overlaps with their other cases. When Chapman, however, had two operating rooms running at the same time, the average overlap was for 2 hours, 59 minutes.

The Times obtained internal surgery data showing when each surgical procedure began and finished. The records do not include patient names or other identifying information.

The Times has interviewed dozens of Swedish patients in recent months. Of the patients who provided detailed records showing the dates and times of their surgeries, 13 show up in the data as having surgeries that overlapped another case. Most said they had never heard or considered that their surgeon might not be doing the entire procedure and that they likely wouldnt have consented if theyd known that.

All 13 patients said they had expected their surgeon to be in the operating room throughout the procedure, and none recalled anyone ever suggesting that would not be the case.

I would have never let it happen like that, said Johnson, who has had troubles lifting her head since a spine procedure with Oskouian. She has difficulty walking and gets help from her daughters to prop her up with pillows at bedtime because she cant sleep lying flat. Her records and the data indicate her 1 hour, 27 minute procedure overlapped with another Oskouian surgery for 43 minutes.

Pearson, whose hands now go through periods of extreme pain in addition to constant numbness and tingling, had complications after his spine surgery that sent him back to the hospital for four weeks and forced him to temporarily use a feeding tube in his abdomen. He said he had chosen and vetted Oskouian as his surgeon and never considered the possibility that his doctor might not be in the operating room the whole time. His entire surgery ran parallel to another Oskouian case.

In consent forms signed before surgery, patients give their surgeon the OK to do the procedure. A recent version of the form said the surgeon will be assisted by a care team that includes doctors in training.

That form didnt mention the prospect that those doctors in training could be doing parts of surgery without the attending doctors supervision.

Katherine Powell, a retired nurse who helped prep patients for the operating room at the Cherry Hill campus, recalled surgeons in the past few years not wanting their patients to know that the doctors were running multiple operating rooms and in some cases asked that their patients be kept separated from each other while they waited for surgery.

Karen Sprague, a nurse who retired at the end of 2015 and prepped patients for surgeries at Swedishs Issaquah facility, said some Oskouian patients began asking questions after noticing other patients arriving or waiting for surgery. Some would wonder who was doing the procedure after a surgical fellow would come in to prep them.

Sprague said she raised the issue with managers, asking what she was supposed to tell patients when multiple surgeries were scheduled to run at the same time. Sprague said she was told to tell the patients that Oskouian was doing the surgery. She didnt feel like that was an honest answer.

How could a man be in two places at the same time? Sprague said.

Hudson said he couldnt speak to the experiences of individual staff members but said Swedish is working to improve transparency for patients.

More than a dozen current and former staff members have expressed concerns in interviews about how little time some surgeons were spending in the operating room. The Times previously reported how fellows at times had to take breaks during surgery to wait for the primary surgeon to return and that surgeons were off seeing patients in the clinic while running two operating rooms. Sometimes the surgeons would miss part of the procedure even if they had just one case going, staffers said.

But the medical records each patient shared with The Times show little indication of the practice. Some of the records track detailed aspects of the surgery such as the time the patient arrived in the OR, the time anesthesia began, and even the times some nurses took breaks during the surgery but they generally dont describe when the surgeon was in the room or what parts of the procedure were performed by the primary surgeon.

Notes filed by the surgeons are often vague when describing how each part of the surgery was performed. Some use the passive voice or we to describe who was doing the work. The records typically say the surgeon was present for the critical portions of the case a standard of involvement required by Medicare, but one that is undefined and instead left to the judgment of the doctor.

While those patient records dont show surgeon in and out times, some anesthesiologists concerned about the practice began tracking surgeon involvement in their notes, according to four people who spoke on condition of anonymity.

Hudson said Swedish is now working to improve how the organization tracks the time surgeons spend in the operating room.

Berkowitz, the woman who spent 41 days in the hospital, first heard of Oskouian from a Swedish doctor who recommended him.

Berkowitz did some vetting. Oskouian had some excellent reviews online. He was leading classes on spine surgeries and doing research. He seemed like the ideal doctor for the job, and Oskouian seemed to agree, telling Berkowitz the planned procedure was something he did all the time and that it would be no problem at all.

The first surgery took place in August 2014. But internal data for that day show Oskouian was running a second surgery that entirely eclipsed Berkowitzs case. The next week, in stage two of Berkowitzs surgery, the same thing happened, according to the data.

In the days that followed, Berkowitz developed a series of problems that forced her to undergo three more surgeries to fix a spinal-fluid leak, redo her spinal-decompression procedure and remove a fluid drain that had inadvertently been sutured to her body, according to records.

Berkowitz said she never even considered the possibility that Oskouian would be running two operating rooms on the days of her procedures. And she said she never would have consented to it if shed known.

Its a very sensitive surgery, Berkowitz said.

Research on overlapping surgeries has shown conflicting results about whether it puts patients at risk.

Last year, the Mayo Clinic examined overlapping elective surgeries at its institution and found no difference in outcomes for those cases compared to nonoverlapping ones. But the study emphasized that its data only applied to the Mayo Clinics handling of overlapping cases and may not extrapolate to other centers.

An examination of three spine surgeons at the University of California, San Francisco found outcomes between overlapping and nonoverlapping cases were mostly similar, except overlapping cases had longer procedure times and lower rates of patients who were discharged back to their homes. Doctors at the University of Toronto, meanwhile, evaluated the outcomes of hip-fracture surgeries and found that overlapping patients faced a higher risk for complications and increased risk the longer the overlap lasted.

Doctors have long debated how to handle busy surgery schedules and the role of fellows in the operating room.

Some doctors see running two operating rooms as inappropriate, undermining the trust of patients who believe their chosen surgeon will be the one at their bedside during the case. Other doctors say the practice is necessary so that sought-after surgeons can utilize their skills efficiently while assistants handle less-important parts of each case. Others fall somewhere in between, greenlighting the start of a second case only once their first case is near conclusion.

Dr. Christopher Smythies, a neurosurgeon in the Seattle area for MultiCare Health who doesnt overlap his cases, said overlapping surgeries are a common and accepted practice in academic and training medical centers. He said the practice can cross a line if the attending surgeon isnt available for critical parts of a surgery and noted that even parts of a case that are typically simple can take an unpredictable turn and suddenly require the attention of an experienced surgeon.

Smythies suspected the consent forms that patients sign are sufficient to give notice of the practice of overlapping surgeries, although he believes many patients would be surprised to learn how those cases are handled in the operating room.

I dont think patients pay close enough attention to consents and probably dont ask enough questions, Smythies said.

After The Boston Globe published a story in 2015 that explored a controversy over surgeons handling multiple cases at Massachusetts General Hospital, the American College of Surgeons (ACS) developed guidelines stating that doctors could do overlapping cases, but said it was inappropriate for doctors to have key portions of two cases happening at the same time. The ACS also said patients need to be informed of the practice.

The role of fellows has also been an issue in Seattle and was recently the subject of a lawsuit against Virginia Mason in a urology case. In that case, the plaintiffs contended that they specifically requested a top doctor handle a procedure only to later learn that a fellow handled the work. The patient developed complications that required months of rebuilding his penis. The couple won an $8.5 million verdict last month.

Chapman, one of the top spine surgeons at Swedish, previously faced a lawsuit involving a double-booked surgery when he was at the University of Washington. A fellow began the 2013 case by meeting the patient, Sharon Rowe, and completing the consent process, according to court filings and partially redacted state records.

The fellow later reported in a letter to the state Department of Health that it was the first time hed seen Rowe. He said he called Chapman on the phone, and Chapman told him to make an incision to start the case, according to the fellows written account. The fellow described that he did the incision, left the room and went to another operating room to begin another Chapman case. Chapman then came in to work on Rowes case.

Rowe developed complications after surgery, including incontinence. The hospital later pointed to surgical notes saying a cauterization device had entered the sacral part of the spine during the incision process and told Rowe in a letter that the primary cause of the surgical complication involved a lack of appreciation of your specific anatomy, according to records.

The state Department of Health concluded that the case was handled within the standard of care. But records obtained by the Times after the newspaper pursued a public-records lawsuit against the UW last year show the university paid a $1.25 million settlement in the case. A UW spokeswoman said in a statement that Rowes outcome and lack of follow-up communication were not acceptable nor in alignment with the standards of our organization.

Last month, UW also introduced a new consent form that explicitly says a patients doctor may participate in an overlapping case. Swedishs new form is similar, requiring patients to put their initials next to a statement that says my surgeon may be scheduled to perform surgery in two operating rooms at the same time.

Tyler Firkins, an attorney considering a lawsuit against Swedish on behalf of a Delashaw patient who has reported failed lower-back surgeries that had to be partially corrected by another doctor, said the issue of double-booked surgeries is one he is exploring. He said the old Swedish consent papers dont adequately inform the patient about the practice of running multiple operating rooms at the same time.

Over the past several weeks, both Swedish and the University of Washington have started using new consent forms that describe the prospect of overlapping surgeries.

I dont think any human being would consent to being in a mill like that, Firkins said.

Firkins said he was planning to seek information from Swedish showing whether his client, Tonya Jilbert, was among those whose case overlapped with another.

Records obtained by the Times indicate her second surgery lasted 70 minutes, with 40 of those minutes overlapping with another case.

Science in the sky: Anatomy of a rainbow – WRAL.com

By Tony Rice

As summer unofficially begins this weekend (summer officially begins here in the northern hemisphere at the solstice, June 21) weve already begun seeing the staple of summer weather in our area: isolated thunderstorms in the afternoon and evening.

As those storms pass, we are often treated to rainbows.

That is just what happened Thursday evening when a series of small storms passed through the area.

Occasional sprinkles didn't impede preparations for Apex High School's year-ending pops concert at Koka Booth Amphitheater in Cary. Showtime was a different story. The combined choirs were barely into the opening song when a small but heavy storm put the show on pause.

Fifteen minutes later, the crowd was rewarded with one of the most brilliant rainbows Ive seen.

You probably know that rainbows are produced by sunlight passing through a raindrop. The light is bent or refracted because the denser water causes the light to travel more slowly. That light, now separated into its component wavelengths (colors), is reflected off the back of the raindrop and back out producing a colorful arc across the sky.

Rainbows are actually circles, centered on a point directly opposite the sun. We see just the portion of that circle above the horizon though. Rainbows most often appear in the early morning and late afternoon. The lower the sun, the more rainbow we see. Look closely and you'll sometimes find much more though.

The large raindrops of that storm and quickly clearing western skies produced an intense rainbow with narrow, well-defined bands of color. Small raindrops produce wider bands of color which overlap recombining those colors to appear more white.

Sometimes a broader, fainter bow appears above the primary bow. This happens as light is reflected once more inside the raindrop. That additional reflection reverses the color order in the secondary bow. Secondary bows are 1.8 times as wide as the primary and less than half the brightness.

Faintly visible just below the primary bow is a supernumerary arc. These alternate pink and green and are the result of interference of light as it exits the water drop.

Light is also reflecting off raindrops. This causes a noticeable brightening of the sky inside the primary bow. Similarly, a noticeable darkening of the sky between the primary and secondary bows is caused as light is reflected away from our eyes. This area is known as Alexanders Dark Band, named for Alexander of Aphrodisias, who first described the phenomenon in AD 200.

Several in the crowd insisted they saw a third dim bow above the secondary bow. They did not. They were looking in the wrong place. In 250 years, only five scientific reports of tertiary rainbows are known to exist.

While each bow is created through the same refractive and reflective process inside raindrops, third (tertiary) and even fourth (quaternary) bows are extremely rare. These form around the sun, not opposite the sun as primary and secondary rainbows do. These higher order rainbows are usually are hidden by the suns glare, conditions have to be just right to see them.

Raymond Lee, a professor of meteorology at the U.S. Naval Academy, and optics expert Philip Laven described the conditions needed to create higher order rainbows in their paper published in Applied Optics in 2011. The sun breaking through dark thunderclouds following a heavy downpour of nearly uniform sized raindrops is required.

The evening of music was topped off when, as if on cue, the International Space Station rose directly behind the stage and over the crowd during the combined orchestra and chorus finale.
