Even a mild case of COVID could wreck your gut’s microbiome, new study finds

¿Por qué un virus respiratorio causaría síntomas gastrointestinales? Es una pregunta que todos nos hemos hecho desde que COVID apareció en escena a fines de 2019. 

Desde el comienzo de la pandemia, los pacientes que contrajeron el virus informaron una amplia gama de síntomas más allá de los problemas respiratorios que podría esperar, incluidas dolencias gastrointestinales como diarrea, náuseas, dolores de estómago y pérdida de apetito.

Los investigadores pueden haber descubierto por qué. Los niveles de bacterias en los microbiomas de los pacientes con COVID estaban bajos en comparación con los de los pacientes sanos que no habían tenido COVID, según un nuevo estudio de la Universidad de Rutgers, publicado el lunes.

Los investigadores recolectaron muestras de heces de 60 personas: 20 que tenían infecciones activas de COVID, 20 que nunca habían experimentado COVID y 20 que se habían recuperado. Encontraron diferencias en las cantidades de 55 especies bacterianas en aquellos con COVID activo, en comparación con aquellos que no habían experimentado la infección o se habían recuperado de ella. 

Los niveles de algunas «bacterias buenas» en general, como Bacteroidaceae y Ruminococcaceae, se  agotaron, mientras que otras como  Faecalibacterium  y el  grupo Eubacterium brachy  estaban por debajo de los niveles óptimos, encontraron los investigadores. Y una sobreabundancia de  Prevotellaceae  continuó después de la infección.

El estudio, que comenzó en mayo de 2020 y finalizó en enero de 2021, analizó a los pacientes al comienzo de la pandemia. Durante ese tiempo, antes de las vacunas y los tratamientos antivirales como Paxlovid, era común que los médicos trataran a los pacientes con COVID con una ronda de antibióticos, en un intento de librar al cuerpo de cualquier infección secundaria que pudiera existir, el Dr. Martin Blaser, autor de el estudio, dijo en un comunicado.

Según Blaser , existían diferencias en los microbiomas intestinales de las personas con COVID, o aquellas que habían estado infectadas previamente, independientemente del uso de antibióticos. Pero fueron más  pronunciados en pacientes que habían sido tratados con antibióticos.

FAA investigating contact between 2 United airplanes on Boston Logan tarmac

The Federal Aviation Administration is investigating a Monday incident between two United Airlines flights at Boston Logan International Airport, the agency said in a statement to CNN.

“As a tow tug was pushing it back from the gate at Boston Logan International Airport, the right wing of United Airlines Flight 515 struck the tail of United Airlines Flight 267 around 8:30 a.m. local time this morning,” the FAA statement said.

“Both aircraft were Boeing 737s that were scheduled for departure,” the statement added.

has reached out to United Airlines and Massport for more information about the incident.

A sudden jolt’
Passenger Nicholas Leone took a photo after the incident and described to CNN what happened.

“I felt a sudden jolt and look to my right to see that the plane had crashed into the still plane, ” he said. “After seeing the fire trucks and police cars, people were a little rattled. Thankfully everyone was able to offboard quickly.”

Passengers said the incident was a little jarring, according to CNN affiliate WHDH in Boston.

“It was just a pretty big shake,” said passenger Martin Neusch. “While we were on the plane, it just clipped the wings, so the two wings clipped each other on the plane.”

The station said passengers on both planes were rebooked on other flights set for Monday afternoon.

The contact between two aircraft on Monday morning follows a string of five close-call incidents earlier this year, including one at Boston Logan last week.

Air traffic controllers stopped a departing private jet from running into a JetBlue flight as it was coming in to land at Logan last Monday night, according to the FAA.

The FAA and the National Transportation Safety Board are investigating that incident.

The two planes involved came within 565 feet (172 meters) of colliding, according to Flightradar24’s preliminary review of its data.

The NTSB is also investigating four other runway incursions involving commercial airliners at major US airports this year.

It’s investigating a possible “runway incursion” in Burbank, California, involving Mesa and SkyWest regional airliners.

Three other incidents have occurred at Honolulu, Austin and New York’s JFK airport this year.

Flambéed pizza thought to have sparked deadly Madrid restaurant fire

A fire believed to have been started by a flambéed pizza has killed two people and injured 12 others at a restaurant in the Spanish capital Madrid, city officials said Saturday.

“It appears the fire started when a flambéed pizza was being served, which set fire to the decorations in the restaurant,” Madrid Mayor Jose Luis Martinez Almeida told Spain’s state television TVE at the scene on Saturday, hours after the late Friday night blaze.

Spanish media reported that a specialty of the restaurant was a pizza in the flambé style – a cooking procedure where spirits are poured on the food and briefly set alight.

“Firefighters told me it was a ferocious fire in the way it started and the smoke it generated, and if the fire station wasn’t just 100 meters (around 330 feet) away, the number of fatalities could have been higher,” said Almeida, speaking to TVE.

Carlos Marin, a Madrid fire department night supervisor, said the restaurant “had just one exit, and since the fire was very close to the door, people went back to the rear of the restaurant, and they were completely trapped,” in videos tweeted by Madrid city emergency services.

The fire was quickly extinguished. Firefighters pulled 12 injured people from the restaurant, and six were taken to a hospital. That was in addition to the two fatalities, said Montse Marcos, a supervisor with the Madrid city ambulance services.

The fire was in the Plaza de Manuel Becerra, on the edge of the Spanish capital’s upscale Salamanca neighborhood.

As Ukraine prepares counteroffensive, Russia appears in disarray

Ukraine’s much-anticipated counteroffensive appears imminent – and the way each side is preparing speaks volumes about their readiness.

Kyiv’s front lines are abuzz with vehicle movement and artillery strikes, with regular explosions hitting vital Russian targets in occupied areas.

Its defense minister has said preparations are “coming to an end” and President Volodymyr Zelensky has assured a counteroffensive “will happen,” while demurring on any exact start date.

It may have already started; it may be weeks away. We don’t know – and that fact is a strong measure of Ukraine’s success as this begins.

Moscow, on the other hand, is in the closing-time bar brawl stage of their war. After losing Kharkiv and Kherson, they have had at least seven months to ready the next likely target of Ukrainian attack: Zaporizhzhia.

That has happened, with vast trench defense networks that can be seen from space. That recognition of their enormity is not necessarily a compliment in 2023. They are big, yes, but they are also something anyone can peruse on Google. That’s not great in an era of precise rockets and speedy armored advances.

But it’s the last 72 hours that have perhaps most betrayed Russia’s lacking readiness.

First, the apparent firing of the deputy defense minister in charge of logistics, Mikhail Mizintsev. The Russian Ministry of Defense has not spelled out his dismissal, merely issuing a decree that Aleksey Kuzmenkov now has his job.

(A caveat: Prigozhin is not the most trustworthy source, and provides little evidence for what he says. But this sort of public spat isn’t something Moscow would encourage at this sensitive moment).

Russia’s eroding ammunition supplies were long known, but to suggest imminent failure just ahead of the counteroffensive smacks of a major bid to shift blame.

The bottom line is, the hours before Ukraine moves are shrinking. The amount we know about their emotional state, or target, is almost zero. And the extent of Moscow’s internal indecision, rivalries and disunity only grows.
