That Toxoplasma gondii looks good on you

Parasite and attractiveness don’t usually go together, but it appears that nobody told Toxoplasma gondii. The world’s most successful parasite affects 30%-50% of the world’s population, and it’s mainly thought to go after the brain in humans, possibly changing behavior and leading to neurological disorders and mental illness.

Now, are you ready to be super confused? According to a recent study, those affected with T. gondii were seen as more attractive and healthy looking, compared with noninfected people. It doesn’t make much sense to us, but it could be an evolutionary thing: The more attractive the parasite makes a person or animal, the more likely it is to spread.

“Some sexually transmitted parasites, such as T. gondii, may produce changes in the appearance and behavior of the human host, either as a by-product of the infection or as the result of the manipulation of the parasite to increase its spread to new hosts,” Javier Borráz-León, PhD, of the University of Turku (Finland), and associates wrote in PeerJ.

Previous research has suggested that men with more testosterone are more likely to become infected because of their behavior with the extra hormones. It’s also been noted that the parasite may manipulate hormones for its own gain, but that’s not proven. Infected women were found to have a lower BMI, more confidence in their appearance, and more partners. Dr. Borráz-León and associates also found that “Toxoplasma-infected subjects had significantly lower facial fluctuating asymmetry than the noninfected people,” ScienceAlert said.

We usually perceive parasites as a bad thing, but honestly this one isn’t sounding too bad. It seems to help with some confidence boosters, and who doesn’t want that? We’re thinking that T. gondii could be the Next Big Thing. All it needs is some marketing and … what if it was covered with nonpareils?

Give it to me straight, Doc. Don’t sugar coat it.

Okay, so he’s not a doctor – not a medical doctor, anyway – but that’s exactly what he did. William H. Grover, PhD, has sugar coated drugs in the name of fraud prevention. We will explain.

The sugar coating comes in the form of nonpareils, the tiny and colorful round sprinkles often found covering small discs of chocolate. Dr. Grover, a bioengineering professor at the University of California, Riverside, who has been working on ways to ensure the authenticity of pharmaceuticals, “started wondering how many different patterns of colored nonpareils were possible on these candies,” he said in a statement from the university.

With just eight colors and an average of 92 individual nonpareils on each candy, the combinations, he found out, are almost endless. Could the same thing be done with a pill? Could the nonpareils be applied as a coating to a pill, giving it a unique pattern that could be stored by the manufacturer and used later as identification?

After much time and effort involving edible cake-decorating glue, Tylenol capsules, smartphones, and computer simulations, he produced CandyCode, an algorithm that converts a photo of a nonpareil-covered pill “into a set of text strings suitable for storing in a computer database and querying by consumers,” the statement explained.

Dr. Grover also mentioned a side benefit: “Anecdotally, I found that CandyCoded caplets were more pleasant to swallow than plain caplets, confirming Mary Poppins’ classic observation about the relationship between sugar and medicine.”

First of all, we can’t believe we just used a Mary Poppins reference. Not exactly what you’d call MDedgey, is it? Second of all, what about the children? We’re talking about drugs that, literally, have been turned into candy. Are the kids going to love them, too? Sounds more like a job for Mr. Yuk.
 

So you want to be a superhero?

Be honest, who didn’t want to be a superhero when they were a kid? There’s a reason every other movie released in the past decade has been a superhero movie. That’s how we’ve ended up with the millionth Batman reboot and Marvel scraping the bottom of the C-list hero barrel. (Seriously, who’d actually heard of Moon Knight before now?)

Point is, we all like to fantasize, and now a meta-analysis from researchers in Germany and the United States has given us all a reason to strike those dashing superhero poses. Through evaluation of 130 studies and over 10,000 people, the researchers found that power posing (and perfect posture) was strongly associated with increased confidence and self-worth. It was also associated with improved behavior, though the connection was less strong.

Sadly though, the research found no connection with power posing and changes in testosterone or cortisol levels. Standing like a superhero may make you feel good, but it won’t give your body any cool powers or superhuman abilities. But don’t despair, because we’re not finished yet. In fact, it may be the biggest news we’ve ever reported for LOTME: A group of scientists from the University of Kentucky has assembled the full genome of a salamander.

Wait, we have more! Beyond having a genome ten times bigger than a human, this salamander, the axolotl from Mexico, is the model of natural regeneration. Name a body part, and the axolotl can grow it back. It can even regenerate portions of its brain. And now that we have access to the complete genome, it’s possible that one day we could use the axolotl’s regeneration for ourselves. Growing back limbs, regenerating spinal cords, the sky’s the limit. And if Wolverine and Deadpool are anything to go by, it’s all you need to get that superhero career off the ground. Salamander powers may not have the cachet of a radioactive spider, but we’ll take what we can get.
 

Post your way to financial hardship

After you pump your gas at the gas station, how do you pay? At the pump or inside? How frequently do you post to your social media pages? What kind of content are you posting?

That kind of nontraditional credit data hasn’t been considered by lenders and credit agencies, but that is changing. The reasoning? It’s opening more opportunities for those without much credit history. But according to a paper published by Janine S. Hiller of Virginia Tech and Lindsay Sain Jones, a financial regulation researcher at the University of Georgia, this just opens a can of worms.

Why is this so dangerous? Well, alternative credit scoring isn’t covered by the Fair Credit Reporting Act or Equal Opportunity Act, so the consumer doesn’t have the ability to dispute any data the credit agencies or lenders receive. Then there’s the “credit boost,” which some companies offer to gain access to the consumer’s data. Often there are no limitations on how long it’s kept. That purchase you made 2 years ago can come back to haunt you.

It also creates a cause for the possibility of discrimination based on “lifestyle-related data points,” which some lenders use to determine creditworthiness: zip code, age, gender, race, socioeconomic status. Even where the consumer went to college is a factor taken under consideration.

“There are all kinds of factors that can be correlated with creditworthiness, but that doesn’t mean they should be used,” Ms. Jones said in the EurekAlert statement.

Let’s say someone applies for a loan needed for a medical procedure. They could be denied because the lender or a credit-reporting agency didn’t like the data they received (most times without the consumer’s consent). Talk about a broken system.

Microscopic evaluation of a dermoscopy-guided skin scraping revealed that this was a case of scabies.

Classically, patients with scabies have many excoriated papules or plaques on their hands, genitals, and trunk with itching so intense that their sleep is interrupted. However, scabies can also be diagnosed in patients who complain of itching but also have very subtle skin findings, such as a small dry patch or fissure (as in this case). Such subtle findings can be easily mistaken for mild hand dermatitis.

In the elderly, itching without a significant rash can arise from many causes. A short list includes dry skin, medications, kidney disease, liver disease, and of course, various dermatologic conditions. Dermoscopy is a sensitive and specific tool for investigating itching and areas of suspected infestation with mites.¹ A mite appears as an oval on dermoscopy, but the most recognizable part is the head and front legs, which appear as a single gray triangle. The photo shows that the most erythematous area around a burrow (black arrows) is an excellent place to start when looking through the dermatoscope. In this case, an area of broken skin was connected to a haphazard tunnel that ultimately led to the mite (white arrows).

Scabies may be effectively treated with topical permethrin 5% applied over every inch of the body from the top of the neck to the tips of the toes.

This topical treatment is left on for at least 8 hours and reapplied a week later. Also, remember to take a careful history of close contacts so that others who are affected may receive treatment.

This patient was treated with permethrin, as was her adult son who lived at home with her and had similar itching. Permethrin comes in 60 g tubes, which is enough to treat 1 adult twice. After 6 weeks, all itching symptoms in the patient had cleared.

Key clinical point: Patients with left-sided breast cancer (BC) who received radiation doses to the left anterior descending artery (LAD) experienced an elevated risk for adverse cardiac outcomes.

Major finding: Mean dose to LAD was associated with an increased risk for any cardiac event (hazard ratio [HR] 1.09; P = .006) and major cardiac events (HR 1.08; P = .022). Receiver operating characteristics analysis identified 2.8 Gy (area under the curve 0.69) as the mean LAD dose threshold, above which the risk for any cardiac event was higher (P = .001).

Study details: Findings are from a retrospective study of 375 consecutively treated female patients with nonmetastatic, left-sided BC who received breast-conserving surgery/mastectomy and adjuvant radiation therapy.

Disclosures: This study did not receive any funding. The authors declared no conflict of interests.

Key clinical point: A breast cancer (BC) diagnosis within 5 years of childbirth (postpartum BC [PPBC]) was associated with worse prognosis than no childbirth prior to diagnosis (nulliparous BC), with the association being strongest in young women diagnosed at the age of <35 years and in those with stage I disease.

Major finding: Women diagnosed with nulliparous BC vs. PPBC at age of <45 years had better overall survival (hazard ratio [HR] 0.61; 95% CI 0.42-0.87), with the difference being more pronounced in women with stage I tumors (HR 0.30; 95% CI 0.11-0.79) and in women diagnosed at the age of ≤35 years (HR 0.44; 95% CI 0.23-0.84).

Study details: The study evaluated a pooled dataset of 2519 women diagnosed with BC at the age of ≥18 years.

Key clinical point: The overall incidence of synchronous bilateral breast cancer (BBC) and metachronous BBC (MBBC) in patients with a history of lobular carcinoma in situ (LCIS) was 2%, with the risk for MBBC being even lower in women with hormone receptor-positive BC and those receiving endocrine therapy (ET).

Major finding: The estimated 5-year risk of developing MBBC was 6.4% (95% CI 1.9%-10.7%) among women with a remaining contralateral breast at risk, with the risk being lower among those with estrogen (hazard ratio [HR] 0.13; P = .015) or progesterone (HR 0.24; P = .047) receptor-positive BC and those who received ET (HR 0.17; P = .005).

Study details: This study included 1651 women with a history of LCIS, of which 249 women developed unilateral or bilateral BC during a median follow-up of 7 years.

Key clinical point: The combination of ibandronate and endocrine therapy (ET) failed to improve disease-free survival (DFS) compared with ET alone in postmenopausal women with estrogen receptor-positive (ER+) early breast cancer (BC).

Major finding: During a median follow-up of 8.5 years, DFS was not significantly different between the ibandronate+ET and ET treatment arms (hazard ratio [HR] 0.97; log-rank P = .811). Overall, the incidence of adverse events, particularly osteonecrosis (P = .002) and dyspepsia (P < .001), was higher in the ibandronate+ET vs. ET treatment arm.

Study details: This phase 3, TEAM-IIB trial included 1116 postmenopausal women with invasive stage I-III ER+ BC who were randomly assigned to receive ET for 5 years with or without 50 mg adjuvant oral ibandronate once daily for 3 years.

Key clinical point: Palbociclib plus endocrine therapy (ET) demonstrated no survival benefit over capecitabine in postmenopausal women with hormone receptor-positive (HR+), human epidermal growth factor receptor 2-negative (HER2−), metastatic breast cancer (BC) who progressed on prior aromatase inhibitor (AI) therapy.

Major finding: The median overall survival was not significantly different between the palbociclib+ET and capecitabine groups in the overall population (adjusted hazard ratio [aHR] 1.00; P = .995) and the wild-type estrogen receptor-1 population (aHR 1.06; P = .683). No new safety signals were identified.

Study details: Findings are from the phase 3 PEARL study including 601 postmenopausal women with HR+/HER2− metastatic BC who progressed on prior AI therapy and were randomly assigned to receive capecitabine or palbociclib+ET with exemestane or fulvestrant.
