Less than half of England has access to Mounjaro on the NHS months after roll-out

Less than half of England has access to tirzepatide (Mounjaro) through their GP, despite the NHS roll-out of the weight-loss jab officially starting over two months ago, an investigation by The BMJ has found.

U.S. survey finds salt substitutes rarely used by people with high blood pressure

Few people with high blood pressure were using salt substitutes, even though they are a simple and effective way to lower sodium intake and manage blood pressure, according to preliminary research presented at the American Heart Association’s Hypertension Scientific Sessions 2025, held in Baltimore, September 4–7, 2025.

Single hair strand could provide biomarker for amyotrophic lateral sclerosis

Researchers at the Icahn School of Medicine at Mount Sinai have shown for the first time that a single strand of hair can reveal unique elemental patterns that distinguish people with amyotrophic lateral sclerosis (ALS) from healthy individuals. The findings, published in eBioMedicine, suggest that a simple, noninvasive hair-based test could one day speed up ALS diagnosis and improve patient care.

Scientists target a key driver of inflammatory responses to curb preterm birth

An MUSC research team reports in Cells that the complement system, part of the body’s natural immune defenses, is a key driver of inflammatory responses that contribute to fetal brain inflammation and preterm birth, the latter of which is the leading cause of complications and death in newborns.

Updated food reactivity tool explains why we eat what we see

Close your eyes and visualize the following: a decadent piece of chocolate cake, a bouquet of fully bloomed red roses, a juicy peach. Hopefully, these mental images produced some form of positive feeling. But is it possible that, despite the feel-good emotions associated with all of them, our brains react differently to food-specific items?

Toddlers showed slightly fewer behavioral problems during COVID-19 pandemic, study finds

Toddlers assessed during the COVID-19 pandemic had slightly fewer emotional and behavioral problems compared to children assessed before the pandemic, suggesting some toddlers may have shown resilience during this time. This finding comes from a study of over 3,000 children across the United States using data from the Environmental influences on Child Health Outcomes (ECHO) Cohort Consortium collected between September 2009 and July 2023.

One dose of antibiotic treats early syphilis as well as three doses, clinical trial shows

Researchers have found that a single injection of the antibiotic benzathine penicillin G (BPG) successfully treated early syphilis just as well as the three-injection regimen used by many clinicians in the United States and elsewhere. These findings from a late-stage clinical trial suggest the second and third doses of conventional BPG therapy do not provide a health benefit.

Single antibody may be responsible for life-threatening reaction to common blood thinner

Researchers at McMaster University have discovered that a rare but dangerous reaction to a widely used blood thinner is caused by a single antibody—overturning decades of medical misunderstanding and opening the door to more precise ways of diagnosing and treating this medical complication.

Routine heart CT scanning not warranted after stenting for left main CAD: ESC Study

Madrid: Routine coronary computed tomography (CCT)-based follow-up after percutaneous coronary intervention (PCI) of the left main coronary artery did not reduce death, myocardial infarction (MI), unstable angina or stent thrombosis compared with symptom-based follow-up, according to late-breaking research presented in a Hot Line session today at ESC Congress 2025

The left main coronary artery supplies a large proportion of the heart muscle and significant left main coronary artery disease is associated with high morbidity and mortality. The introduction of coronary stents along with the improvements in technology and pharmacological management has increased the use of PCI in these high-risk patients with similar results achieved compared with coronary artery bypass grafting.

“Detrimental complications, such as stent restenosis, and recurrent ischaemic events can occur after left main PCI; however, the optimal surveillance strategy remains a subject of debate,” explained trial presenter, Doctor Ovidio De Filippo from Hospital Citta Della Salute e della Scienza di Torino, Turin, Italy.

“In recent years, CCT has emerged as a valuable tool for diagnosis and monitoring, providing accuracy comparable to invasive angiography, while minimising procedural risks and reducing healthcare costs. We conducted the first randomised trial to evaluate the potential benefit of routine CCT-based follow-up at 6 months compared with standard symptom- and ischaemia-driven management in patients after PCI for left main disease.”

PULSE was an open-label, blinded-endpoint, investigator-initiated, randomised trial conducted at 15 sites in Europe and South America.

Participants were consecutive patients with critical stenosis undergoing PCI for left main coronary artery disease. Participants were randomised 1:1 to either a CCT-guided follow-up at 6 months (experimental arm) or standard symptom and ischaemia-driven management (control arm). Participants were followed for an additional 12 months (total follow-up 18 months).

In the CCT arm, if significant left main in-stent restenosis was detected, patients underwent invasive coronary angiography followed by target lesion revascularisation if in-stent restenosis was confirmed. If any significant stenosis was detected in a different site, management was conducted according to the current guidelines. In the standard-of-care arm, patients were managed per clinical guidelines and according to each centre’s standard practice. The primary endpoint was a composite of all-cause death, spontaneous MI, unstable angina or definite/probable stent thrombosis at 18 months.

A total of 606 patients were randomised who had a mean age of 69 years and 18% were female. CCT was performed in 89.8% of patients in the experimental arm at a median of 200 days.

A primary-endpoint event occurred in 11.9% of patients in the CCT arm and 12.5% of patients in the control arm at 18 months (hazard ratio [HR] 0.97; 95% confidence interval [CI] 0.76 to 1.23; p=0.80).

There was a reduced risk of spontaneous MI in the CCT arm vs. the control arm (0.9% vs. 4.9%; HR 0.26; 95% CI 0.07 to 0.91; p=0.004). An increase in imaging-triggered target-lesion revascularisation was observed in the CCT arm compared with the control arm (4.9% vs. 0.3%; HR 7.7; 95% CI 1.70 to 33.7; p=0.001); however, the incidence of clinically driven target-lesion revascularisation was similar between the arms (5.3% vs. 7.2%; HR 0.74; 95% CI 0.38 to 1.41; p=0.32).

Summing up the main findings, Principal Investigator, Professor Fabrizio D’Ascenzo, also from Hospital Citta Della Salute e della Scienza di Torino, said: “Systematic 6-month CCT-based follow-up did not result in a reduction in 18-month all-cause death, spontaneous MI, unstable angina and stent thrombosis. While universal CCT-based follow-up may not be useful, the marked reduction in spontaneous MI and identification of obstructive lesions requiring repeat PCI suggest this approach may be worth investigating further in selected patients with complex anatomies and over longer follow-up.”
