Surgeon General Calls For Health Warnings On Social Media For Adolescents
U.S. Surgeon General, Dr. Vivek Murthy, has proposed warning labels on social media platforms to alert parents about the mental health risks for adolescents. This advisory highlights the psychological harm caused by platforms like TikTok, Instagram, and Snapchat. Dr. Murthy suggests these warnings, akin to those on tobacco and alcohol products, address an urgent public health issue. 📱
The hope is that the advisory will influence tech companies to prioritize user safety, share data with researchers, and enhance content moderation.
Dr. Murthy also suggested parents should establish tech-free zones and model responsible online behavior, while researchers focus on social media's impact on youth mental health.
The advisory notes that children are particularly vulnerable to cyberbullying and harmful content, which can worsen mental health issues like depression and anxiety.

Kansas Sues Pfizer Over Alleged Misleading COVID-19 Vaccine Claims
Kansas has filed a lawsuit against Pfizer, accusing the pharmaceutical giant of misleading the public about the safety and efficacy of its COVID-19 vaccine. The lawsuit alleges that Pfizer concealed risks such as pregnancy complications and heart inflammation, and exaggerated the vaccine's effectiveness against variants. 💉
The state claims these actions violate the Kansas Consumer Protection Act and seeks unspecified damages. Pfizer has denied the allegations, stating that it has been transparent about the vaccine's safety and efficacy data.
Kansas Attorney General Kris Kobach emphasized that the lawsuit aims to hold Pfizer accountable for alleged false advertising and misleading statements. The state asserts that Pfizer's actions have caused harm to Kansas residents by influencing their decisions about vaccination based on incomplete or inaccurate information.
Pfizer maintains that its communications and disclosures have been truthful and that the vaccine has significantly contributed to public health efforts globally.

Nature Retracts Influential 2002 Paper on Adult Stem Cell Plasticity
Nature has retracted a highly cited 2002 paper from Catherine Verfaillie's lab that claimed adult stem cells could differentiate into any cell type. The retraction follows years of scrutiny and unresolved data integrity issues, despite corrections in 2007. 📑
KU Leuven's investigation found no misconduct by Verfaillie but identified problems with image duplications. These issues led to the paper's retraction. Verfaillie, now an emeritus professor at KU Leuven, and most co-authors agreed to the retraction.
The original study had significant implications for stem cell research, suggesting that adult stem cells could offer a versatile alternative to embryonic stem cells. However, doubts about the reproducibility of the findings have persisted, impacting the field's direction.

Tenecteplase In Late-Window Stroke Shows No Benefit Over Placebo
Clinical Question: In patients with acute ischemic stroke, does tenecteplase administered between 4.5 to 24 hours after symptom onset improve clinical outcomes compared to placebo?
Bottom Line: The TIMELESS trial found that administering tenecteplase 4.5 to 24 hours after the onset of acute ischemic stroke did not significantly improve clinical outcomes compared to placebo. The primary outcome, measured by the modified Rankin scale (mRS) at 90 days, showed no significant difference between the two groups. Both groups had a median mRS score of 3. Secondary outcomes, including functional independence and reperfusion rates, also did not differ significantly. Safety outcomes, such as mortality and symptomatic intracranial hemorrhage, were similar between the tenecteplase and placebo groups. Read more at NEJM.
Spaceflight-Induced Renal Remodeling
Clinical Question: What are the renal health consequences of long-term spaceflight exposure to microgravity and galactic cosmic radiation (GCR) on astronauts?
Bottom Line: Long-term exposure to spaceflight conditions, including microgravity and simulated galactic cosmic radiation, leads to significant renal dysfunction in both animal and human models. These effects include renal transporter dephosphorylation, which may increase the risk of kidney stones as a primary renal phenomenon rather than solely a secondary consequence of bone loss. Additionally, spaceflight induces remodeling of the nephron, resulting in an expansion of distal convoluted tubule size and a decrease in overall tubule density. Exposure to Mars roundtrip dose-equivalent GCR causes renal damage and dysfunction, highlighting the need for targeted renal protection strategies during prolonged deep space missions.

A 6-year-old boy presents with a sudden onset of swelling around his eyes and ankles for the past week. His parents report that he has been otherwise healthy, with no recent illnesses or medications. On examination, he has 3+ pitting edema in both lower extremities. Urinalysis shows 4+ proteinuria with a spot urine protein-to-creatinine ratio of 4.5. Renal ultrasound reveals normal-sized kidneys without any structural abnormalities. A kidney biopsy shows diffuse effacement of podocyte foot processes without significant glomerular sclerosis or immune complex deposits.
