Paragraph: The article does a good job of noting the cost of the combing salons, as well ascost of the medicinal shampoos and other drug treatments, specifically noting also that insurance may not cover the costs. The article cites data from a recent review article in a medical journal that outlines the effectiveness (or lack thereof) of the medicinal treatments. "The medications have been found to be from 68% to 87% effective after one or two applications. Most don't require combing," the story says. We do wish they story explained what "67% effective" meansfor a typical person, however. The careful reader will note that the evidence for the effectiveness of the featured combing salons is mostly anecdotal, and it would have greatly strengthened the article to have been more explicit about this, as well as including more solid proof that standard lice medications are not as effective as they used to be. The article notes that various organizations and experts consider the chemical/medicinal treatments to be highly safe as well as effective. The story needed to be more explicit about the quality of evidence for each of the treatment options mentionedcombing, going to a delousing salon, over-the-counter treatments, prescription treatments. Only the latter are mentioned in the context of research. The story references a review article that compares the different approaches, but it provides no details on what kind of evidence the review is based on. No disease mongering here, and we were glad the story pointed out thatthere are no adverse physical health effects from lice. The article does a very good job of noting the conflicts of interest of those quoted. The story explored alternatives. Good job on this. It's clearthat businesses that assist with combing are easy to find, and over-the-countershampoos are even easier. What appears to be "new" is the explosion of combing salons and newer prescription shampoos, as well as the review article published last week that evaluates them. This story doesn't appear to rely on a news release. Claim: New Ways to Fight Super Lice
The treatment of childhood cases of head lice infestations is a popular news media perennial at the start of the school year, and this Wall Street Journal storyfalls into that category. It covers the usual elements prevalence of the infestations among school age children, over-the-counter and prescription treatments, home remedies (which generally don't work) and reassurance about the pesky but essentially benign health impact. This story also takes a look at the rise of "lice-combing" salons and newer medications meant to stand in when older medications are ineffective. We were impressed by the depth of the sourcing, along withthe details that helped readers assess anypotential conflicts of interest among said sources. One thing we wished had been more detailed: How the evidence stacks up for each of the treatments. As the article itself makes clear, head lice infestationisa widespread, unpleasant, and disruptive albeit relatively benign condition that costs millions of families money, aggravation and time in efforts to prevent and treat. Adding to the nuisance of ridding scalps, tresses, clothing and home furnishings of the pests, some of the historic over-the-counter medicinal treatments have lost their power owing to drug-resistant mutations in the lice. Newer prescription medicines are effective, but worry an apparently growing number of parents who work hard to avoid what they consider unnecessary chemical exposure. Thus, parents are certain to be looking for the best and latest information about treatments.

Paragraph: On July 14 2019, a Facebook user shared a photograph purportedly illustrating the risks posed by grill brushes and the metal they can leave behind attaching to food that is consumed. In an attached status update, the poster warned:I would suggest to anyone that has a metal brush to clean your grill get rid of it. This is the result of eating a bristle off of one. I am looking at a long recovery. at Pelham Medical Center.In the attached image, an exposed abdomen bears a long and painful-looking scar with more thantwenty staples. No other details about the image were included with the post, but the obvious inference was that this was the result of surgery that was required after inadvertently ingesting metal fragments left on a grill by a cleaning brush.No information was included about how the injury manifested or which symptoms people already exposed to grilled foods might exhibit. However, news stories from previous years indicated that even if rare, summer grilling has occasionally led to people accidentally consuming food with grill brush debris attached.In May 2015, CBSreportedthat a Connecticut woman had been treated for the same injury. Her symptoms were described as a "sharp" and "unusual" pain:[In May 2015], a woman in Connecticut needed emergency surgery to remove a wire barbecue brush bristle from her digestive tract and doctors say she's not the first. Cheryl Harrison of Wallingford, Connecticut, was rushed to the hospital by her husband after feeling a sharp and unusual pain in her stomach.That pain was caused by a single stray bristle that had fallen off the metal grill cleaning brush and found its way into the hamburger she ate. She came into the emergency room within a day because of severe abdominal pain. After a CT scan showed the wire, doctors were able to remove it from her stomach through laparoscopic surgery.The article went on to describe a similar case in which the patient was not made aware of the injury as quickly. One doctor stated the injury was difficult to identify because the small size of the bristles meant they were difficult to find:Dr. Aziz Benbrahim, her general surgeon at MidState Medical Center, told CBS News she was lucky because she came in right away. A previous patient of his who had a grill brush wire stuck in his system waited for a couple of weeks. It had punctured his intestine."I had to open him up completely, " said Benbrahim. "Then we remove this wire and we found out also why he had chest pain because he also had pulmonary embolism, which is a blood clot in his lungs.""He was just lucky he was still alive," he added. "All from this wire."[]"Nobody knows the statistics, that's the problem. The only paper published talks about 6 or 7 cases and I believe it's a much, much more common," Benbrahim said. "When I was talking to my colleagues at the hospital, I was surprised that all of them had at least one or two patients like this. I didn't think it was that common. And this isn't a very big hospital, so I assume that in a bigger hospital they would have more."The story further noted that in one hospital, at least six patients had similarinjuries from ingesting grill brush wire over an 18-month period. One year later, WTSP reported that a man in Florida was injured the same way:A warning if you plan to fire up the grill this holiday weekend. A Lakeland man discovered a hidden health hazard the hard way, and it could be on your grill right now."This is my little parting gift," says Clif Hennecy. It's a souvenir from the doctor's office that Hennecy never imagined his doctor would find stuck in his stomach during a routine checkup."It's just a tiny, little bristle, but it's stainless steel," says Hennecy.The Lakeland man says the metal bristle came from the brush he used to use to clean his grill."It's a scary proposition having one of those lodged inside your stomach. It can cause abscesses, and cause infections, and it can cause people to die," Hennecy says.And in July 2017, a boy in Canada was hurtwhen he swallowed wire fragments:Jenna Kuchik was kicking back after a July 4 [2017] barbecue with her fiance and three children when her 4-year-old son, Oliver Schenn, began to scream in pain.Terrified, Kuchik ran for the EpiPen. Oliver, whom Kuchik and her fiance, Matt Schenn, affectionately call Ollie, has a severe nut allergy. But the boy was not exhibiting any of symptoms of a reaction only choking, screaming and crying.Twenty-four hours and two hospitals later, Ollie would emerge from surgery after doctors removed two tiny metal fibers from his esophagus. The culprit: the family's wire barbecue brush.That outlet included some statistics about frequency, noting it was low but acute, and possiblyunderreported:Barbecue brushes have caused an estimated 1,698 emergency room visits from 2002 to 2014, according to a study published in 2016 in the journal Otolaryngology-Head and Neck Surgery. The rate of injuries is low when compared to similar emergencies, like children ingesting batteries, but the study's lead, Dr. David Chang, associate professor at the University of Missouri's department of otolaryngology, believes the data underrepresents the total volume of injuries. Urgent care clinics and primary care doctors likely see many similar cases that aren't covered by the data in Chang's study.A 2018 Consumer Reports article provided alternative methods of cleaning a grill without the ubiquitous wire brush:Consider alternative cleaning tools. Depending on what type of grill you have, you might try cleaning warm grill grates with a tool such as a pumice stone or a coil-shaped bristle-free brush. Check your owner's manual for recommendations You can also brush loose food particles off a warm grate with a wad of crumpled-up aluminum foil. Make sure grill grates are not hot enough to burn you.The claim about ingesting grill brush wires and requiring hospitalization represents a known but rare risk. Experts advise anyone who experiences symptoms like stomach pain after consuming grilled food to seek medical attention. Instead of using a wire grill brush, consumer safety advocates advise alternative grill cleaning methods, such as aluminum foil. Claim: People sometimes ingest metal fragments from grill brushes and become seriously injured.
Can Grill Brushes Cause You to Ingest Metal and Become Ill?

Paragraph: The number of EU nurses coming to the UK has fallen by 90% since the Brexit vote. The number of nurses and midwives from the EEA joining the Nursing and Midwifery Council's register fell by 91% from 2015/16 to 2017/18. The number of EU nationals leaving the NHS jumped by 14% in 2017. EU nationals have fallen as a percentage of those joining the NHS. EU nationals made up 8% of new staff (whose nationality was known) joining the NHS in England in the year to June 2018. That compares to 11% in the year to June 2016. It's possible that the number in June 2016 was unusually high. Claim 1 of 4 Claim: There's been an increase in the number of EU staff in the NHS since the referendum.
Around 4,400 more EU nationals worked for the NHS in England in June 2018, compared to June 2016. But some of the increase could be down to more staff reporting their nationality. The proportion of staff who report they are EU nationals is about the same in 2018 as in 2016.
