Another 3 million Americans file for unemployment benefits - CNN - 0 views

  • Millions of Americans are relying on unemployment benefits for their livelihoods after losing their jobs to the coronavirus crisis.
  • Another 3 million people filed initial unemployment claims last week on a seasonally adjusted basis,
  • It was the eighth week in a row that the number for initial claims decreased after peaking at 6.9 million in the final week of March
  • ...6 more annotations...
  • But now that initial claims have been falling for two months straight, economists are beginning to shift their focus to continuing jobless claims, which count people who are filing multiple weeks in a row. That number stood at 22.8, up slightly from the prior week.
  • Federal and state outlays totaled just under $102 billion, as of May 12, up from $12.7 billion at the beginning of March.
  • In April, the federal government paid out nearly $27 billion in unemployment benefits as the money from Congress' historic enhancement to the program started to flow, Treasury Department data shows.
  • Lawmakers in late March approved a $600 boost to weekly payments for up to four months and added 13 weeks to benefits, both compliments of the federal government
  • States, meanwhile, delivered just over $21 billion in benefits in April, up from about $4 billion the month before.
  • As more Americans join and remain on the unemployment insurance program, spending will continue to skyrocket. The outlays to date show that states have struggled to handle the surge in claims and to implement the federal provisions, said Ernie Tedeschi, an economist at Evercore ISI and former Treasury official.

'Life or death still possible': 31 days at my dad's virtual bedside - CNN - 0 views

  • The attending physician at the intensive care unit had called that morning and asked whether they should include a Do Not Resuscitate order in my dad's chart. They had asked before. I had been indecisive. A successful resuscitation would extend his life. But it might also lead to brain damage.
  • "If it continues in this direction," he told me, "we're talking about a single-digit chance of survival."
  • I suspected that my father had a will and a health care directive inside the house. I put on my mask but couldn't find a clean pair of latex gloves in my duffel bag. It was cold in the backyard. I had a pair of leather gloves. I put those on and entered my childhood home for the first time in weeks. My mother barely registered my presence. She was crying on the couch.
  • ...28 more annotations...
  • I was relieved -- we wouldn't have to make what felt like an impossible decision -- but then I kept reading. My father had noted that he did not want to be supported by a ventilator or hooked up to a feeding tube for any length of time. He had been connected to both for nearly two weeks.
  • There was grief on her face, but also curiosity. What had finally gotten to her younger son, the one who so rarely showed emotion during his father's hospitalization?
  • I called the hospital and approved the DNR. They told me his status was still dire. I called my dad's closest friends and started preparing them for the worst.
  • My father's lungs showed no signs of progress. The double pneumonia they diagnosed days before was worsening. His kidneys were failing. Dialysis was required but would put a strain on his blood pressure, which was already dangerously low. There was a special form of dialysis designed for delicate situations like this -- continuous veno-venous hemofiltration -- but it wasn't available at Lawrence
  • The morning after I searched for my father's health directive and drafted his obituary, I woke up and tried to turn on my laptop. It wouldn't start. When it eventually booted up, it asked if I wanted to restore an unsaved document. No, I thought, let's see what happens today.
  • It was the same doctor as yesterday, the one who asked about the DNR. "Look, your dad is on a ventilator. That's a form of life support. He's experiencing kidney failure and requires dialysis. His situation is still very acute. He was in good health before the Covid, but his kidney, heart, and lungs are 69 years old. It's tough for them to recover. But the numbers from today are undeniably better than yesterday. There's been an improvement at almost every level. Your dad is a tough guy."
  • One of my close friends, a nurse practitioner, would help me understand all the terminology and its implications. He was treating Covid patients at an ICU upstate. At the end of our calls I'd ask him how he was doing. "We ran out of gowns," he told me one day. "My ICU is out of ventilators -- we're diverting people to Albany," he said another time.
  • "There's a difference between good intentions and good outcomes," I explained to her. She would wave me away and pick up. Inevitably the call would bring her tears. I stewed on the porch. My brother, uncle and I would spend hours trying to ease her mind and pacify her anxiety. Any inquiry or outreach was like sticking a finger in the open wound of her anguish.
  • I called my friend, the nurse practitioner, and gave him the latest update. He seemed upset. "You OK, dude?" "A nurse from my hospital died," he explained.
  • The nurses and doctors who took care of my father -- first for four days at NewYork-Presbyterian Lawrence Hospital, then for nearly a month at NewYork-Presbyterian/Columbia -- were always empathetic, straightforward and willing to trust me with complicated details.
  • About a week after writing -- then refusing to recover -- my father's obituary, his condition was continuing to improve.
  • "He's only improving," I told her, "because of the life-saving care you guys have given him. The whole city is in awe of you. They should have a parade for you down the Canyon of Heroes."
  • Covid-19 was new and largely unstudied. Maybe one of these seemingly odd treatments would work.
  • "Yesterday was a stumble, but we're getting back on course," I emailed the group. "We always knew this recovery wasn't going to be a straight line. It's important to remain resilient and optimistic even when there are temporary setbacks."
  • "Oh Lou, I've been waiting for your call. I have such good news. They are planning to extubate him tomorrow. They are going to take your father off the ventilator!" She was practically screaming with excitement. I was speechless.
  • I had been withholding certain information from my family and friends during this whole ordeal. My dad had developed a blood clot two weeks into his hospitalization. Clots are extremely dangerous, of course, but it was small and in a relatively manageable location.
  • I called my brother and told him about the plan to get my father off the ventilator. Since there were a number of contingencies, we debated telling my mother. She was living and dying with every update.
  • My father's breathing was labored on the morning they were planning to extubate. They delayed the procedure a day. That next morning, April 16, a doctor called. I was in the shower and rushed out to answer my cell. He said they were doing the extubation within the hour. What do we want to do if the extubation fails?
  • "It went as well as we could have hoped for," the doctor said. "His vitals are stable and he's breathing well. He's resting now." She explained that my father was disoriented and it probably wasn't a great idea to speak with him that day. Whatever, I thought, I'll speak with him when he gets home. He had been on a ventilator for 28 days.
  • I called the doctor later in the day. She told me my dad seemed distressed. He was trying to speak, but his vocal cords were too swollen. "It's so frustrating," she told me. "I don't know what he wants to tell me."
  • "Each facility has their own Covid rules," she explained. "I'll send you over a list." On the list was the nursing home where my grandfather had died several years before. My father had visited him every day.
  • I called the step-down unit where he had been the past three days. They transferred me to his nurse. "He's doing better, love. We took him off the pressor and his blood pressure is in a good range. His heart rate is good. He's breathing fine. The doctors decided he didn't need to go back to the ICU. He's ok."
  • "I've repeatedly said that recovery isn't a straight line. ... Yesterday we managed the roller coaster ride as a family. My brother, uncle and I were with my mother the entire day. We never lost hope or confidence in my dad's medical care and ultimate recovery. If there's a light at the end of the tunnel, it's a blinking one. Right now, it shines again."
  • I drove back to my mom's house. I scanned the block for my brother's car. He had not arrived. I parked. I have to wait for him and then tell my mother, brother and uncle all at once, right? Should I call my wife first? Should I call my dad's best friend?
  • I called my wife. I called my dad's best friend. I called the guys he grew up with. I called his former colleagues. I began every conversation the same way, "This is that call." I listened to each of them yell and cry and ask if I was serious. Then I said I had to make another call.
  • I wrote about my father's career. How he got his law degree at night school and became a prosecutor at the city, state, and federal level. How he convicted mobsters, drug dealers, and those who abused power.
  • I wrote about my dad's volunteer work -- at the Special Olympics, at an organization he founded that helps police families with special needs, and at just about any Italian-American group that needed a lawyer. He was so proud of his Italian-American heritage. He loathed the mafioso caricatures and stereotypes found on TV -- he wrote countless op-eds attacking those -- but he revered the old-school virtues he associated with his Italian-American upbringing: loyalty, humility, hard work, dedication to family.
  • He was a Covid patient for 31 days. It was a painful experience, but ultimately unimportant. It doesn't matter how a man dies. It matters how he lives.

Global economy coronavirus bailout reaches $7 trillion and counting - CNN - 0 views

  • The response to the coronavirus pandemic has been unprecedented in terms of speed and scale. Commitments from governments and central banks to date are close to $7 trillion, according to an analysis by CNN Business. The total includes government spending, loan guarantees and tax breaks, as well as money printing by central banks to buy assets such as bonds and stock funds.
  • The figure includes the $2 trillion US relief package working its way through Congress and an anticipated 30 trillion yen ($274 billion) in stimulus from Japan that could be approved next month. In Europe, CNN Business tallied stimulus efforts by the biggest economies: Germany, France, the United Kingdom, Italy and Spain.
  • "The [$2 trillion US] stimulus package is likely the bare minimum needed to offset the current drag from the outbreak," Bank of America economist Joseph Song told clients Thursday. "The economy will likely need close $3 [trillion] in fiscal stimulus, if not more."

2020 election: Experts are warning coronavirus puts integrity the election at risk. Her... - 0 views

  • As states scramble to delay their spring primaries, election professionals and voting experts are anxiously looking ahead to November and warning that the coronavirus pandemic is already threatening the safety and integrity of the next presidential election.
  • Congress took a step forward this week by approving $400 million in federal grants that states can use to make coronavirus-related adjustments for the general election. But the two parties couldn't reach a deal on the politically-charged question of how to overhaul the voting laws.
  • "At all costs, the election must go on," said CNN presidential historian Douglas Brinkley. "This is not the NBA season or the Olympics. Come November, we've got to vote. If we can vote in the middle of the Civil War, and if Franklin D. Roosevelt can run for an unprecedented fourth term in the middle of World War II, then we can figure out how to make 2020 a free and fair election."

  • More than 136 million Americans voted in 2016, and a record number of them cast early ballots. But nearly 60% of voters still showed up on Election Day, waited in long lines, used communal pens and touched the same voting machines -- all dangerous moves in the coronavirus era.

Opinion | Mass testing has its problems. They're nothing compared to not testing. - The... - 1 views

  • Short of a vaccine, mass testing is among the most plausible paths back to some kind of normalcy.
  • Imagine a world where you could stop at a drive-through testing center, get a result in 20 minutes or so, and then motor onward to your dinner party with a “negative” certificate in hand. Imagine outdoor kiosks at airports, with a negative test result required to get inside. Imagine offices, even restaurants or bars, with a nurse stationed in the parking lot.
  • Would this be annoying and cumbersome? Yes. Would it be a vast improvement on what we are doing now? Also yes. It even seems plausible since Abbott Labs has won emergency approval for a test that costs $5, returns an answer in 15 minutes, requires no specialized equipment and can be produced in bulk. Mass deployment of this test, or others like it, could fundamentally change how we approach covid-19.
  • ...10 more annotations...
  • No test is perfectly accurate; all generate false positives and false negatives. How many varies by the test — the new Abbott Labs test, for example, has a false negative rate of about 3 percent and a false positive rate of about 1.5 percent.
  • We’d also require public understanding that test results are a risk-assessment tool rather than a definitive answer. And shifting the public’s thinking might be harder than shifting Trump.
  • Doing that would also require fundamentally changing our thinking.
  • For mass testing to work, people will need to understand that even an event where all attendees just tested negative isn’t necessarily covid-free, because some false negatives might have slipped through
  • Giving hundreds of millions of citizens this crash course in elementary statistics would be very difficult. Teaching people how to think about a positive result would be even harder — especially if mass testing does its job of reducing caseloads. Because as case numbers fall, false positives will become a bigger and bigger problem.
  • Say we’re testing 200 people, 10 of whom have covid-19. Given its rate of false negatives, the Abbott test would probably catch all 10. But with false positives, it could also tell one or two people who don’t have covid-19 that they’re infected. That’s not ideal — as good citizens, they’d have to go home and quarantine. But a more sensitive follow-up test could substantially mitigate this problem, shortening such quarantines to a day or so. It would be worth it to get those 10 true positives out of circulation.
  • Doing this, we might eventually reduce the share of the population that’s infected to, say, 0.5 percent from 5 percent. Unfortunately, the false positive rate won’t budge, so now for every one true positive uncovered, roughly three false positives would still be generated.
  • That’s inherently costly: Every false positive means skipping your flight, rehearsal or birthday party. But it would be catastrophic if people didn’t understand that a positive covid-19 test is a guideline, not a guarantee
  • People who think that they’ve had covid-19, when they haven’t, are apt to go out and engage in risky behavior, maybe a lot of it. And if mass testing ever becomes common, there could be a lot of those people.
  • So mass testing isn’t just a matter of getting a test that is cheap enough and plentiful enough; the administration and the public must be educated to use this bounty wisely. That’s a hard messaging problem. Given the alternative, though, it’s the kind of problem we’d really like to have.

Twitter settles after feds claim it used 2FA info to target ads - 0 views

  • Twitter reached a $150 million settlement with the Department of Justice and Federal Trade Commission over alleged misrepresentations of its data privacy practices, the agencies announced on Wednesday.
  • The settlement, which still needs to be approved by a federal judge, would resolve claims from the government that Twitter did not adequately inform its users about how their contact information would be used to target ads rather than just secure their accounts, in violation of the FTC Act and a 2011 settlement it reached with the agency.
  • The agencies alleged Twitter told users it collected phone numbers and email addresses to secure their accounts with two-factor authentication, but did not disclose it also used that information to help advertisers target their messages.

  • “The $150 million penalty reflects the seriousness of the allegations against Twitter, and the substantial new compliance measures to be imposed as a result of today’s proposed settlement will help prevent further misleading tactics that threaten users’ privacy.” 
  • The settlement is the latest attempt by U.S. law enforcers to apply consumer protection law to alleged data privacy violations.
  • “Keeping data secure and respecting privacy is something we take extremely seriously, and we have cooperated with the FTC every step of the way,” he added.

Opinion | The Alt-Right Manipulated My Comic. Then A.I. Claimed It. - The New York Times - 1 views

  • Legally, it appears as though LAION was able to scour what seems like the entire internet because it deems itself a nonprofit organization engaging in academic research. While it was funded at least in part by Stability AI, the company that created Stable Diffusion, it is technically a separate entity. Stability AI then used its nonprofit research arm to create A.I. generators first via Stable Diffusion and then commercialized in a new model called DreamStudio.
  • hat makes up these data sets? Well, pretty much everything. For artists, many of us had what amounted to our entire portfolios fed into the data set without our consent. This means that A.I. generators were built on the backs of our copyrighted work, and through a legal loophole, they were able to produce copies of varying levels of sophistication.
  • eing able to imitate a living artist has obvious implications for our careers, and some artists are already dealing with real challenges to their livelihood.
  • ...4 more annotations...
  • Greg Rutkowski, a hugely popular concept artist, has been used in a prompt for Stable Diffusion upward of 100,000 times. Now, his name is no longer attached to just his own work, but it also summons a slew of imitations of varying quality that he hasn’t approved. This could confuse clients, and it muddies the consistent and precise output he usually produces. When I saw what was happening to him, I thought of my battle with my shadow self. We were each fighting a version of ourself that looked similar but that was uncanny, twisted in a way to which we didn’t consent.
  • In theory, everyone is at risk for their work or image to become a vulgarity with A.I., but I suspect those who will be the most hurt are those who are already facing the consequences of improving technology, namely members of marginalized groups.
  • In the future, with A.I. technology, many more people will have a shadow self with whom they must reckon. Once the features that we consider personal and unique — our facial structure, our handwriting, the way we draw — can be programmed and contorted at the click of a mouse, the possibilities for violations are endless.
  • I’ve been playing around with several generators, and so far none have mimicked my style in a way that can directly threaten my career, a fact that will almost certainly change as A.I. continues to improve. It’s undeniable; the A.I.s know me. Most have captured the outlines and signatures of my comics — black hair, bangs, striped T-shirts. To others, it may look like a drawing taking shape.I see a monster forming.

How a dose of MDMA transformed a white supremacist - BBC Future - 0 views

  • February 2020, Harriet de Wit, a professor of psychiatry and behavioural science at the University of Chicago, was running an experiment on whether the drug MDMA increased the pleasantness of social touch in healthy volunteers
  • The latest participant in the double-blind trial, a man named Brendan, had filled out a standard questionnaire at the end. Strangely, at the very bottom of the form, Brendan had written in bold letters: "This experience has helped me sort out a debilitating personal issue. Google my name. I now know what I need to do."
  • They googled Brendan's name, and up popped a disturbing revelation: until just a couple of months before, Brendan had been the leader of the US Midwest faction of Identity Evropa, a notorious white nationalist group rebranded in 2019 as the American Identity Movement. Two months earlier, activists at Chicago Antifascist Action had exposed Brendan's identity, and he had lost his job.
  • ...40 more annotations...
  • "Go ask him what he means by 'I now know what I need to do,'" she instructed Bremmer. "If it's a matter of him picking up an automatic rifle or something, we have to intervene."
  • As he clarified to Bremmer, love is what he had just realised he had to do. "Love is the most important thing," he told the baffled research assistant. "Nothing matters without
  • When de Wit recounted this story to me nearly two years after the fact, she still could hardly believe it. "Isn't that amazing?" she said. "It's what everyone says about this damn drug, that it makes people feel love. To think that a drug could change somebody's beliefs and thoughts without any expectations – it's mind-boggling."
  • Over the past few years, I've been investigating the scientific research and medical potential of MDMA for a book called "I Feel Love: MDMA and the Quest for Connection in a Fractured World". I learnt how this once-vilified drug is now remerging as a therapeutic agent – a role it previously played in the 1970s and 1980s, prior to its criminalisation
  • He attended the notorious "Unite the Right" rally in Charlottesville and quickly rose up the ranks of his organisation, first becoming the coordinator for Illinois and then the entire Midwest. He travelled to Europe and around the US to meet other white nationalist groups, with the ultimate goal of taking the movement mainstream
  • some researchers have begun to wonder if it could be an effective tool for pushing people who are already somehow primed to reconsider their ideology toward a new way of seeing things
  • While MDMA cannot fix societal-level drivers of prejudice and disconnection, on an individual basis it can make a difference. In certain cases, the drug may even be able to help people see through the fog of discrimination and fear that divides so many of us.
  • in December 2021 I paid Brendan a visit
  • What I didn't expect was how ordinary the 31-year-old who answered the door would appear to be: blue plaid button-up shirt, neatly cropped hair, and a friendly smile.
  • Brendan grew up in an affluent Chicago suburb in an Irish Catholic family. He leaned liberal in high school but got sucked into white nationalism at the University of Illinois Urbana-Champaign, where he joined a fraternity mostly composed of conservative Republican men, began reading antisemitic conspiracy books, and fell down a rabbit hole of racist, sexist content online. Brendan was further emboldened by the populist rhetoric of Donald Trump during his presidential campaign. "His speech talking about Mexicans being rapists, the fixation on the border wall and deporting everyone, the Muslim ban – I didn't really get white nationalism until Trump started running for president," Brendan said.
  • If this comes to pass, MDMA – and other psychedelics-assisted therapy – could transform the field of mental health through widespread clinical use in the US and beyond, for addressing trauma and possibly other conditions as well, including substance use disorders, depression and eating disorders.
  • A group of anti-fascist activists published identifying information about him and more than 100 other people in Identity Evropa. He was immediately fired from his job and ostracised by his siblings and friends outside white nationalism.
  • When Brendan saw a Facebook ad in early 2020 for some sort of drug trial at the University of Chicago, he decided to apply just to have something to do and to earn a little money
  • At the time, Brendan was "still in the denial stage" following his identity becoming public, he said. He was racked with regret – not over his bigoted views, which he still held, but over the missteps that had landed him in this predicament.
  • About 30 minutes after taking the pill, he started to feel peculiar. "Wait a second – why am I doing this? Why am I thinking this way?" he began to wonder. "Why did I ever think it was okay to jeopardise relationships with just about everyone in my life?"
  • Just then, Bremmer came to collect Brendan to start the experiment. Brendan slid into an MRI, and Bremmer started tickling his forearm with a brush and asked him to rate how pleasant it felt. "I noticed it was making me happier – the experience of the touch," Brendan recalled. "I started progressively rating it higher and higher." As he relished in the pleasurable feeling, a single, powerful word popped into his mind: connection.
  • It suddenly seemed so obvious: connections with other people were all that mattered. "This is stuff you can't really put into words, but it was so profound," Brendan said. "I conceived of my relationships with other people not as distinct boundaries with distinct entities, but more as we-are-all-on
  • I realised I'd been fixated on stuff that doesn't really matter, and is just so messed up, and that I'd been totally missing the point. I hadn't been soaking up the joy that life has to offer."
  • Brendan hired a diversity, equity, and inclusion consultant to advise him, enrolled in therapy, began meditating, and started working his way through a list of educational books. S still regularly communicates with Brendan and, for his part, thinks that Brendan is serious in his efforts to change
  • "I think he is trying to better himself and work on himself, and I do think that experience with MDMA had an impact on him. It's been a touchstone for growth, and over time, I think, the reflection on that experience has had a greater impact on him than necessarily the experience itself."
  • Brendan is still struggling, though, to make the connections with others that he craves. When I visited him, he'd just spent Thanksgiving alone
  • He also has not completely abandoned his bigoted ideology, and is not sure that will ever be possible. "There are moments when I have racist or antisemitic thoughts, definitely," he said. "But now I can recognise that those kinds of thought patterns are harming me more than anyone else."
  • it's not without precedent. In the 1980s, for example, an acquaintance of early MDMA-assisted therapy practitioner Requa Greer administered the drug to a pilot who had grown up in a racist home and had inherited those views. The pilot had always accepted his bigoted way of thinking as being a normal, accurate reflection of the way things were. MDMA, however, "gave him a clear vision that unexamined racism was both wrong and mean," Greer says
  • Encouraging stories of seemingly spontaneous change appear to be exceptions to the norm, however, and from a neurological point of view, this makes sense
  • Research shows that oxytocin – one of the key hormones that MDMA triggers neurons to release – drives a "tend and defend" response across the animal kingdom. The same oxytocin that causes a mother bear to nurture her newborn, for example, also fuels her rage when she perceives a threat to her cub. In people, oxytocin likewise strengthens caregiving tendencies toward liked members of a person's in-group and strangers perceived to belong to the same group, but it increases hostility toward individuals from disliked groups
  • In a 2010 study published in Science, for example, men who inhaled oxytocin were three times more likely to donate money to members of their team in an economic game, as well as more likely to harshly punish competing players for not donating enough. (Read more: "The surprising downsides of empathy.")
  • According to research published this week in Nature by Johns Hopkins University neuroscientist Gül Dölen, MDMA and other psychedelics – including psilocybin, LSD, ketamine and ibogaine – work therapeutically by reopening a critical period in the brain. Critical periods are finite windows of impressionability that typically occur in childhood, when our brains are more malleable and primed to learn new things
  • Dölen and her colleagues' findings likewise indicate that, without the proper set and setting, MDMA and other psychedelics probably do not reopen critical periods, which means they will not have a spontaneous, revelatory effect for ridding someone of bigoted beliefs.
  • In the West, plenty of members of right-wing authoritarian political movements, including neo-Nazi groups, also have track records of taking MDMA and other psychedelics
  • This suggests, researchers write, that psychedelics are nonspecific, "politically pluripotent" amplifiers of whatever is going on in somebody's head, with no particular directional leaning "on the axes of conservatism-liberalism or authoritarianism-egalitarianism."
  • That said, a growing body of scientific evidence indicates that the human capacity for compassion, kindness, empathy, gratitude, altruism, fairness, trust, and cooperation are core features of our natures
  • As Emory University primatologist Frans de Waal wrote, "Empathy is the one weapon in the human repertoire that can rid us of the curse of xenophobia."
  • Ginsberg also envisions using the drug in workshops aimed at eliminating racism, or as a means of bringing people together from opposite sides of shared cultural histories to help heal intergenerational trauma. "I think all psychedelics have a role to play, but I think MDMA has a particularly key role because you're both expanded and present, heart-open and really able to listen in a new way," Ginsberg says. "That's something really powerful."
  • "If you give MDMA to hard-core haters on each side of an issue, I don't think it'll do a lot of good,"
  • if you start with open-minded people on both sides, then I think it can work. You can improve communications and build empathy between groups, and help people be more capable of analysing the world from a more balanced perspective rather than from fear-based, anxiety-based distrust."
  • In 2021, Ginsberg and Doblin were coauthors on a study investigating the possibility of using ayahuasca – a plant-based psychedelic – in group contexts to bridge divides between Palestinians and Israelis, with positive findings
  • "I kind of have a fantasy that maybe as we get more reacquainted with psychedelics, there could be group-based experiences that build community resiliency and are intentionally oriented toward breaking down barriers between people, having people see things from other perspectives and detribalising our society,
  • "But that's not going to happen on its own. It would have to be intentional, and – if it happens – it would probably take multiple generations."
  • Based on his experience with extremism, Brendan agreed with expert takes that no drug, on its own, will spontaneously change the minds of white supremacists or end political conflict in the US
  • he does think that, with the right framing and mindset, MDMA could be useful for people who are already at least somewhat open to reconsidering their ideologies, just as it was for him. "It helped me see things in a different way that no amount of therapy or antiracist literature ever would have done," he said. "I really think it was a breakthrough experience."

  • Especially, the colonic EMG signal of the beagles with STC was remarkably enhanced by CES (Figure 3), indicating that CES could not only improve the colonic content emptying, but also enhance the EMG signal to promote colonic motility.
  • Colonic electrical stimulation (CES), a valuable alternative for the treatment of STC, was reported to improve the colon motility by adjusting the bioelectrical activity in animal models or patients with STC [17]. However, little report focuses on the underlying nervous mechanism to normalize the delayed colonic emptying and relieve symptoms. We hypothesized that CES may also repair the disorders of the relevant nerves and then improve the colonic motility.
  • The first study regarding the CES to modulate colonic motility was performed by Hughes et al. [37]. Since then, many researchers employed short-pulse CES in canine descending colon or pig cecum [20,21,38]. Researchers also applied long-pulse CES to stimulate the colon of human or animals [39]
  • Recently, studies showed that the prokinetic effect of pulse train CES is better than that of short-pulse CES or long-pulse CES [25]
  • Our study indicated that CES could enhance the colonic motility, and then accelerate the colonic content emptying. Thereafter, we investigated the underlying mechanism and presumed that CES might improve the STC symptom through the repairment of the ENS.
  • The neuropathy in ENS is considered to be responsible for various kinds of disordered motility including STC and the related pathophysiologic symptoms [40]. In agreement with this view, our study discovered the decreased number of ganglia in the myenteric plexus, as well as the destruction of the enteric nerve axon terminals and synaptic vesicles in the sham CES group beagles
  • The present study proves that CES with pulse trains has curative effects on the colonic motility and content emptying in STC beagles. The up-regulation of intestinal nerve related proteins such as SYP, PGP9.5, CAD and S-100B in the colonic myenteric plexus suggests that CES might reduce the degeneration of the myenteric plexus neurons, thereby producing the therapeutic effect on STC beagles. Further investigation for the underlying mechanism of nerve regeneration is necessary to better understand how CES promotes the recovery of delayed colonic motility induced by STC.
