Good morning!<\/b>
Neurotech startups are betting big on your brainwaves. \ud83c\udfa7 A $700 pair of EEG-equipped headphones <\/span>just launched<\/a><\/span>, claiming to monitor focus dips and even early signs of dementia or depression. Apple and Google are circling too, with patents hinting at brain-scanning earbuds. It\u2019s the latest example of diagnostics sneaking into everyday wearables. Meanwhile, the pager has yet to weigh in on burnout. <\/span><\/p>\n<\/div>\n
\n
Today\u2019s issue takes 5 minutes to read<\/span>. Only got one? Here\u2019s what to know: <\/p>\n<\/div>\n
\n
\n
\n
Quitting smoking raises recovery odds in addiction treatment <\/p>\n<\/li>\n
\n
1\/3 of US adults unaware of HPV vaccine <\/p>\n<\/li>\n
\n
Eye drops that could replace reading glasses <\/p>\n<\/li>\n
\n
Air Canada, union reach tentative deal <\/p>\n<\/li>\n
\n
White coat trust persists while gender bias lingers <\/p>\n<\/li>\n
\n
Canada\u2019s wildfires could smolder into fall displacing thousands <\/p>\n<\/li>\n<\/ul>\n<\/div>\n
\n
Let\u2019s get into it. <\/p>\n<\/div>\n
\n
\n
Staying #Up2Date <\/span>\ud83d\udea8<\/h1>\n<\/div>\n<\/div>\n
\n
\n
1: Quitting smoking boosts recovery odds<\/b><\/span><\/p>\n<\/div>\n
\n
A <\/span>cohort study<\/a><\/span> of 2,652 people with substance use disorders found those who quit smoking had a 30% higher chance of recovery (OR 1.30; 95% CI, 1.07\u20131.57). Since smoking rates are disproportionately high among people with SUDs, the findings suggest quitting cigarettes isn\u2019t just good for the lungs \u2014 it may be a powerful lever in addiction recovery itself.<\/span><\/p>\n<\/div>\n
\n
2: HPV awareness still lags in US<\/b><\/span><\/p>\n<\/div>\n
\n
A <\/span>national cross-sectional survey<\/a><\/span> found 34.3% of US adults had never heard of HPV, and 37.6% didn\u2019t know about the vaccine. Even among those who did, awareness of its link to oral cancer was far lower than for cervical cancer. With vaccination most effective early in life, that gap in public knowledge could blunt one of our best cancer-prevention tools.<\/span><\/p>\n<\/div>\n
\n
3: Antithrombotics work equally in men and women<\/b><\/span><\/p>\n<\/div>\n
\n
A <\/span>systematic review<\/a><\/span> and <\/span>meta-analysis<\/a><\/span> of 33 trials found more intensive antithrombotic therapy reduced heart attack risk by ~15% in both men and women. Major bleeding remained a significant risk (no sex-based difference), but efficacy was also consistent (P for interaction >0.05). The bottom line: these therapies deliver the same safety and efficacy regardless of gender \u2014 though vigilance on bleeding is still critical.<\/span><\/p>\n<\/div>\n<\/div>\n
\n
\n
Drops That Replace Reading Glasses<\/span><\/h1>\n<\/div>\n<\/div>\n
\n
\n
Could a tiny drop replace your reading glasses? Here\u2019s what to know<\/i><\/p>\n<\/div>\n
\n
What happened: <\/b><\/span>The FDA approved a new prescription eye drop that helps people ditch their glasses without losing their sight. <\/p>\n<\/div>\n
\n
Why it matters: <\/b><\/span>Also known as Vizz, the drops are made by the pharmaceutical company Lenz<\/a>\u00a0 Therapeutics<\/a>. Taken daily, the drops treat age-related blurry near vision (presbyopia) for up to 10 hours at a time.<\/a> Presbyopia usually shows up in the early 40s and affects more than 1 in 5 people worldwide. It\u2019s reported more often in North America, likely because of easier access to eye exams.\u00a0The usual solution is getting a pair of reading glasses \u2014 or squinting at menus and tiny print while pretending you can read. <\/p>\n<\/div>\n
\n
Vizz offers a different approach. It works with the help of aceclidine, a chemical that creates a \u201cpinhole effect,\u201d<\/a> narrowing the pupil like a camera lens so close-up text appears sharper. Unlike other eye drops<\/a> that are marketed to treat presbyopia, Vizz doesn\u2019t cause a \u201czoomed-in\u201d effect or blur distance vision. The FDA recently approved the drops and claims they don\u2019t cause brow heaviness due to ciliary muscle activation. <\/p>\n<\/div>\n
\n
$\"A$ <\/p>\n
<\/p>\n
Giphy<\/p>\n
<\/a><\/div>\n<\/div>\n<\/div>\n
\n
But: <\/b><\/span>Don\u2019t throw out those reading glasses just yet. Vizz isn\u2019t a permanent solution, and the FDA guidance<\/a> said users may experience temporary dim or dark vision after use. In rare cases, the drops have caused retinal tears and detachments in people with pre-existing retinal diseases. In clinical trials, 20% of participants reported eye irritation, and 13% reported headaches.\u00a0 <\/p>\n<\/div>\n
\n
So far, there isn\u2019t a clear vision for when Health Canada will approve Vizz for Canadians, but a report from Eyes on Eyecare stated that Lenz teamed up with European pharmaceutical company Th\u00e9a to help bring Vizz to Canada<\/a>. Until then, the product will be available in the US by October of this year. <\/p>\n<\/div>\n
\n
Bottom line: <\/b><\/span>The thought of never having to pull out a pair of glasses to read a patient's chart again is tempting, but until Health Canada gets on board, you might want to leave the reading glasses where they belong (in your pocket and every room of the house). <\/p>\n<\/div>\n<\/div>\n

1: \u2708\ufe0f Air Canada\u2019s flight attendants have reached a tentative deal<\/a>, ending the strike that grounded thousands of flights and disrupted summer travel. The union says the agreement resolves unpaid work \u2014 a key sticking point in negotiations \u2014 while the airline will gradually resume operations over the next week. Passengers affected by cancellations can request refunds or rebookings<\/a>, though limited capacity during peak season may still keep some plans on hold. <\/p>\n<\/div>\n
\n
\ud83e\ude7a White coats still scream \u201ctrust me, I\u2019m a doctor\u201d \u2014 but women wearing them often get mistaken for nurses, finds a BMJ Open review<\/a>. Patient preferences varied by setting: casual clothes worked in primary care, but white coats or scrubs were preferred in emergencies, and specialties like ortho, surgery, derm, and OBGYN leaned toward coats. COVID-era hygiene habits boosted acceptance of scrubs and masks, but the bottom line is the same: white coats aren\u2019t going anywhere, and neither are the gendered biases that come with them. <\/p>\n<\/div>\n
\n
\ud83e\uddec A new gel could let burns heal without scars. The \u201cskin in a syringe\u201d<\/a> combines fibroblast cells on gelatin beads with hyaluronic acid, letting wounds rebuild real dermis instead of scar tissue. In mice, the cells survived, produced skin components, and even formed new blood vessels \u2014 and with elastic hydrogel threads also in the mix, researchers say scar-free burn care may one day move from possibility to practice. <\/p>\n<\/div>\n
\n
4: \ud83d\udd25 Canada\u2019s wildfires aren\u2019t slowing down<\/a> \u2014 7.8 million hectares have already burned, and officials say the blazes could keep smoldering into fall as record heat and drought drag on. More than 13,000 Indigenous residents are still displaced, and smoke continues to blanket parts of the US. What used to be a summer crisis is starting to look permanent. <\/p>\n<\/div>\n<\/div>\n
