COVID-19 tied to muscle-weakening disease; vaping risk documented
COVID-19 tied to muscle-weakening disease; vaping risk documented

(Reuters) – The following is a roundup of some of the latest scientific studies on the novel coronavirus and efforts to find treatments and vaccines for COVID-19, the illness caused by the virus.
Neuromuscular disease may be triggered by COVID-19
Researchers have added the muscle-weakening disease myasthenia gravis to the list of neurological problems linked to severe COVID-19. Tremors, seizures, impaired consciousness and other nervous system issues already have been tied to severe COVID-19. In some instances, the virus appears to trick the body into attacking the brain by triggering the immune system to produce so-called autoantibodies, which mistakenly target a person’s own tissues or organs. In myasthenia gravis, autoantibodies attack nerve connections to muscles, and skeletal muscles involving breathing and moving parts of the body become weak after activity. On Monday in the journal Annals of Internal Medicine, doctors described three patients without previous neurological or autoimmune disorders whose symptoms of myasthenia gravis began within a week after fevers related to COVID-19 started. The time from the coronavirus infection to the beginning of myasthenia gravis symptoms “is consistent with the time from infection to symptoms in other neurologic disorders triggered by infections,” the researchers said. They added that the findings add to “the growing evidence of other neurologic disorders with presumed autoimmune mechanisms after COVID-19 onset.” (bit.ly/2PPI1wo)
Vaping by young people linked to higher COVID-19 risk
Vaping appears to be tied to markedly increased risks for getting COVID-19 among U.S. teens and young adults. Researchers analyzed nationally representative survey data collected in May from 4,351 participants ages 13-24 years in a study published on Tuesday in the Journal of Adolescent Health. Those who used both cigarettes and e-cigarettes in the previous 30 days were 4.7 times more likely to report having experienced COVID-19 symptoms compared with those who never smoked or vaped. Among participants who tested for COVID-19, those who used just e-cigarettes were five times more likely to report a positive test. Those who had ever used both e-cigarettes and cigarettes were seven times more likely to be diagnosed with COVID-19. Dr. David Christiani of Harvard T.H. Chan School of Public Health, who was not involved in the research, told Reuters there are many reasons why people who vape would be at increased risk of getting COVID-19. Studies have shown that “vaping liquids impair local immunity in the nose and the rest of the respiratory tract. Once those defenses are impaired, it’s going to make people more viable to infection,” Christiani said. Also, the study authors noted, vaping involves repeated touching of the mouth and face, which is associated with the spread of the virus. (reut.rs/33QGZZu; bit.ly/2XQR9oX)
Face masks could someday help diagnose illness
Some face masks are effective at limiting the spread of COVID-19, some are not – and some, researchers said, might eventually help diagnose illnesses unrelated to the coronavirus. Researchers reported in the journal Science Advances that N95 masks are most effective, as long as they do not have a valve that lets the wearer’s exhaled breath escape. Next most effective are surgical masks, followed by multiple-layer cotton masks. Bandanas only minimally curb the escape of exhaled droplets. Fleece fabrics worn around the neck and pulled over the face “seemed to disperse the largest droplets into a multitude of smaller droplets” that remain airborne longer, so they “might be counterproductive,” the researchers said. A separate report in the journal Analytical Chemistry explains that while molecules in exhaled breath can reveal disease, collecting enough molecules to diagnose a problem requires breathing into tubes or bags. But a specific kind of fiber insert placed inside a mask can collect enough molecules while wearers go about their usual activities. After volunteers wore the masks with the inserts, examining the fiber insert using mass spectrometry let researchers see even trace amounts of exhaled particles. (bit.ly/33RR2gR; bit.ly/2XX6qVA)
Certain immune responses may contribute to severe COVID-19

Researchers who compared innate immune responses – the body’s first line of defense – in patients with coronavirus infections and in healthy people found multiple differences that could shed light on COVID-19 and why some cases become so severe. There were differences, for example, in the amounts and functioning of various types of cells in blood, in gene activity in cells isolated from blood, and in levels of inflammatory molecules. In particular, three molecules that were elevated in severely ill patients – called LIGHT, Oncostatin-M and EN-RAGE – are linked with lung inflammation but have not previously been seen in COVID-19 patients, the researchers reported on Tuesday in the journal Science. Severely ill patients also had bacterial debris, such as bacterial DNA and cell-wall materials, in their blood. The more debris, the sicker the patient, and the more inflammatory substances circulating in the blood. But surprisingly, “although there were enhanced levels of inflammatory molecules in plasma, the blood cells themselves were in a state of functional sluggishness, and failed to respond efficiently to stimulation,” senior author Bali Pulendran of Stanford University told Reuters. Overall, Pulendran said, “the study yields mechanistic insights and potential therapeutic targets for COVID-19.” (bit.ly/31NSZs7)

Las Vegas Strip faces growing bed bug problem
With huge events including Formula 1, CES, and the Super Bowl looming, the Las Vegas Strip faces an issue that could be a major cause for concern.

Las Vegas beat the covid pandemic.
It wasn't that long ago when the Las Vegas Strip went dark and people questioned whether Caesars Entertainment, MGM Resorts International, Wynn Resorts, and other Strip players would emerge from the crisis intact.
Related: Las Vegas Strip report shares surprising F1 race news
In the darkest days, the entire Las Vegas Strip was closed down and when it reopened, it was not business as usual. Caesars Entertainment (CZR) - Get Free Report and MGM reopened slowly with all sorts of government-mandated restrictions in place.
The first months of the Strip's comeback featured temperature checks, a lot of plexiglass, gaming tables with limited numbers of players, masks, and social distancing. It was an odd mix of celebration and restraint as people were happy to be in Las Vegas, but the Strip was oddly empty, some casinos remained closed, and gaming floors were sparsely filled.
When vaccines became available, the Las Vegas Strip benefitted quickly. Business and international travelers were slow to return, but leisure travelers began bringing crowds back to pre-pandemic levels.
The comeback, however, was very fragile. CES 2022 was supposed to be Las Vegas's return to normal, the first major convention since covid. In reality, surging cases of the covid omicron variant caused most major companies to pull out.
Even with vaccines and covid tests required, an event that was supposed to be close to normal, ended up with 25% of 2020's pre-covid attendance. That CES showed just how quickly public sentiment — not actual danger — can ruin an event in Las Vegas.
Now, with November's Formula 1 Race, CES in January, and the Super Bowl in February all slated for Las Vegas, a rising health crisis threatens all of those events.

The Las Vegas Strip has a bed bug problem
While bed bugs may not be as dangerous as covid, Respiratory Syncytial Virus (RSV), Legionnaires’ disease, and some of the other infectious diseases that the Las Vegas Strip has faced over the past few years, they're still problematic. Bed bugs spread easily and a small infestation can become a large one quickly.
The sores caused by bed bugs are also a social media nightmare for the Las Vegas Strip. If even a few Las Vegas Strip visitors wake up covered in bed bug bites, that could become a viral nightmare for the entire city.
In late-August, reports came out the bed bugs had been at seven Las Vegas hotel, mostly on the Strip over the past two years. The impacted properties includes Caesars Planet Hollywood and Caesars Palace as well as MGM Resort International's (MGM) - Get Free Report MGM Grand, and others including Circus Circus, The Palazzo, Tropicana, and Sahara.
VISIT LAS VEGAS: Are you ready to plan your dream Las Vegas Strip getaway?
"Now, that number is nine with the addition of The Venetian and Park MGM. According to the health department report, a Venetian guest reported seeing the bloodsuckers on July 29 and was moved to another room. An inspection three days later confirmed their presence," Casino.org reported.
The Park MGM bed bug incident took place on Aug. 14.
Bed bugs remain a Las Vegas Strip problem
Only Tropicana, which is soon going to be demolished, and Sahara, responded to Casino.org about their bed bug issues. Caesars and MGM have not commented publicly or responded to requests from KLAS or Casino.org.
That makes sense because the resorts do not want news to spread about potential bed bug problems when the actual incidents have so far been minimal. The problem is that unreported bed bug issues can rapidly snowball.
The Environmental Protection Agency (EPA) shares some guidelines on bed bug bites on its website that hint at the depth of the problem facing Las Vegas Strip resorts.
"Regularly wash and heat-dry your bed sheets, blankets, bedspreads and any clothing that touches the floor. This reduces the number of bed bugs. Bed bugs and their eggs can hide in laundry containers/hampers. Remember to clean them when you do the laundry," the agency shared.
Normally, that would not be an issue in Las Vegas as rooms are cleaned daily. Since the covid pandemic, however, some people have opted out of daily cleaning and some resorts have encouraged that.

Not having daily room cleaning in just a few rooms could lead to quick spread.
"Bed bugs spread so easily and so quickly, that the University of Kentucky's entomology department notes that "it often seems that bed bugs arise from nowhere."
"Once bed bugs are introduced, they can crawl from room to room, or floor to floor via cracks and openings in walls, floors and ceilings," warned the University's researchers.

Americans are having a tough time repaying pandemic-era loans received with inflated credit scores
Borrowers are realizing the responsibility of new debts too late.

With the economy of the United States at a standstill during the Covid-19 pandemic, the efforts to stimulate the economy brought many opportunities to people who may have not had them otherwise.
However, the extension of these opportunities to those who took advantage of the times has had its consequences.

Credit Crunch
A report by the Financial Times states that borrowers in the United States that took advantage of lending opportunities during the Covid-19 pandemic are falling behind on actually paying back their debt.
At a time when stimulus checks were handed out and loan repayments were frozen to help those affected by the economic shock of Covid-19, many consumers in the States saw that lenders became more willing to provide consumer credit.
According to a report by credit reporting agency TransUnion, the median consumer credit score jumped 20% to a peak of 676 in the first quarter of 2021, allowing many to finally have “good” credit scores. However, their data also showed that those who took out loans and credit from 2021 to early 2023 are having an hard time managing these debts.
“Consumer finance companies used this opportunity to juice up their growth at a time when funding was ample and consumers’ finances had gotten an artificial boost,” Chief economist of Moody’s Analytics Mark Zandi told FT. “Certainly a lot of lower-income households that got caught up in all of this will feel financial pain.”
Moody’s data shows that new credit cards accounts that were opened in the first quarter of 2023 have a 4% delinquency rate, while the same rate in September 2022 was 4.5%. According to the analysts, these levels were the highest for the same point of the year since 2008.
Additionally, a study by credit scoring company VantageScore found that credit cards issued in March 2022 had higher delinquency rates than cards issued at the same time during the prior four years.

Credit cards were not the only debts that American consumers took on. As per S&P Global Ratings data, riskier car loans taken on during the height of the pandemic have more repayment problems than in previous years. In 2022, subprime borrowers were becoming delinquent on new cars loans at twice the rate of pre-pandemic levels.
S&P auto loan tracker Amy Martin told FT that lenders during the pandemic were “rather aggressive” in terms of signing new loans.
Bill Moreland of research group BankRegData has warned about these rising delinquencies in the past and had recently estimated that by late 2022, there were hundreds of billions of dollars in what he calls “excess lending based upon artificially inflated credit scores”.
The Government's Role

Because so many are failing to pay their bills, many are wary that the government assistance may have been a financial double-edged sword; as they were meant to alleviate financial stress during lockdown, while it led some of them to financial difficulty.
The $2.2 trillion Cares Act federal aid package passed in the early stages of the pandemic not only put cash in the American consumer’s pocket, but also protected borrowers from foreclosure, default and in some instances, lenders were barred from reporting late payments to credit bureaus.
Yeshiva University law professor Pam Foohey specializes in consumer bankruptcy and believes that the Cares Act was good policy, however she shifts the blame away from the consumers and borrowers.
“I fault lenders and the market structure for not having a longer-term perspective. That’s not something that the Cares Act should have solved and it still exists and still needs to be addressed.”

Inflation: raising interest rates was never the right medicine – here’s why central bankers did it anyway
We need to start cutting rates, but there’s something that has to happen first.

Inflation remains too high in the UK. The annual rate of consumer price inflation to September was 6.7%, the same as a month earlier. This is well below the 11.1% peak reached in October 2022, but the failure of inflation to keep falling indicates it is proving far more stubborn than anticipated.
This may prompt the Bank of England’s Monetary Policy Committee (MPC) to raise the benchmark interest rate yet again when it meets in November, but in my view this would not be entirely justified.
In reality, the rate hikes that began two years ago have not been very helpful in tackling inflation, at least not directly. So what’s the problem and is there a better alternative?
Right policy, wrong inflation
Raising interest rates is the MPC’s main tool for trying to get inflation back to its target rate of 2%. The idea is that this makes it more expensive to borrow money, which should reduce consumer demand for goods and services.
The trouble is that the type of inflation recently witnessed in the UK seems less a problem of excessive demand than because costs have been rising for manufacturers and service providers. It’s known as “cost-push inflation” as opposed to “demand-pull inflation”.
Inflation rates (UK, US, eurozone)

Production costs have risen for several reasons. During the COVID-19 pandemic, central banks “created money” through quantitative easing to enable their governments to run large spending deficits to pay for furloughs and other interventions to help citizens through the crisis.
When countries started reopening, it meant people had money in their pockets to buy more goods and services. Yet with China still in lockdown, global supply chains could not keep pace with the resurgent demand so prices went up – most notably oil.
Oil price (Brent crude, US$)

Then came the Ukraine war, which further drove up prices of fundamental commodities, such as energy. This made inflation much worse than it would otherwise have been. You can see this reflected in consumer price inflation (CPI): it was just 0.6% in the year to June 2020, then rose to 2.5% in the year to June 2021, reflecting the supply constraints at the end of lockdown. By June 2022, four months after Russia’s invasion of Ukraine, CPI was 9.4%.
The policy problem
This begs the question, why has the Bank of England (BoE) been raising rates if it’s unlikely to be effective? One answer is that other central banks have been raising rates. If the BoE doesn’t mirror rate rises in the US and eurozone, investors in the UK may move their money to these other areas because they’ll get better returns on bonds. This would see the pound depreciating against the US dollar and euro, in turn increasing import prices and aggravating inflation.
Part of the problem has been that the US has arguably faced more of the sort of demand-led inflation against which interest rates are effective. For one thing, the US has been less at the mercy of rising energy prices because it is energy self-sufficient. It also didn’t lock down as uniformly as other major economies during the pandemic, so had a little more space to grow.
At the same time, the US has been more effective at bringing down inflation than the UK, which again suggests it was fighting demand-driven price rises. In other words, the UK and other countries may to some extent have been forced to follow suit with raising interest rates to protect their currencies, not to fight inflation.
What next
How harmful have the rate rises been in the UK? They have not brought about a recession yet, but growth remains very weak. Lots of people are struggling with the cost of living, as well as rent or mortgage costs. Several million people are due to be hit by much higher mortgage rates as their fixed-rate deals end between now and the end of 2024.
UK GDP growth (%)

If hiking interest rates is not really helping to curb inflation, it makes sense to start moving in the opposite direction before the economic situation gets any worse. To avoid any damage to the pound, the answer is for the leading central banks to coordinate their policies so that they cut rates in lockstep.
Unless and until this happens, there would seem to be no quick fix available. One piece of good news is that the energy price cap for typical domestic consumption was reduced from October 1 from £1,976 to £1,834 a year. That 7% reduction should lead to consumer price inflation coming down significantly towards the end of 2023.
More generally, the Bank of England may simply have to hope that world events move inflation in the desired direction. A key question is going to be whether the wars in Ukraine and Israel/Gaza result in further cost pressures.
Unfortunately there is a precedent for a Middle East conflict leading to a global economic crisis: following the joint assault on Israel by Syria and Egypt in 1973, Israel’s retaliation prompted petroleum cartel OPEC to impose an oil embargo. This led to an almost fourfold increase in the price of crude oil.
Since oil was fundamental to the costs of production, inflation in the UK rose to over 16% in 1974. There followed high unemployment, resulting in an unwelcome combination that economists referred to as stagflation.
These days, global production is in fact less reliant on oil as renewables have become a growing part of the energy mix. Nonetheless, an oil price hike would still drive inflation higher and weaken economic growth. So if the Middle East crisis does spiral, we may be stuck with stubborn, untreatable inflation for even longer.
