University students are less physically active and more sedentary than older adults in their 70s, NUS study finds

University students accumulate less daily physical activity and more sedentary time than older adults, with significant public health implications. The study highlights the need to rethink public health messaging and redesign urban environments to promote incidental movement in younger generations.

Researchers identify ANKRD11 as a brake on T-cell responses to chronic hepatitis B virus and cancer

Researchers identified ANKRD11 as a key regulator that suppresses CD8+ T cell activity during chronic hepatitis B virus infection and cancer. ANKRD11 deficiency reprograms CD8+ T cell differentiation to enhance immunity in chronic infection and cancer, making it a potential therapeutic target.

Zipalertinib plus chemotherapy significantly extends progression-free survival in first-line EGFR exon 20 insertion-positive NSCLC

The REZILIENT 3 trial found a six-month improvement in median progression-free survival with the combination of zipalertinib and platinum-pemetrexed chemotherapy. The study showed a 50% reduction in disease progression or death and a substantially higher response rate compared to chemotherapy alone.

Phase 3 DESTINY-Lung04 trial shows first-line trastuzumab deruxtecan significantly improves progression-free survival in HER2-mutant NSCLC

The Phase 3 DESTINY-Lung04 trial showed that trastuzumab deruxtecan significantly improves progression-free survival in patients with HER2-mutant non-small cell lung cancer, with a median PFS of 14.3 months compared to 8.3 months with pembrolizumab plus chemotherapy. T-DXd also demonstrated a higher objective response rate and better d...

In the PAPILLON study, first-line amivantamab-chemotherapy demonstrates the longest overall survival reported for EGFR exon 20 insertion-positive advanced NSCLC

The PAPILLON study demonstrates the longest overall survival for patients with EGFR exon 20 insertion-positive advanced NSCLC using first-line amivantamab-chemotherapy. The study found a median overall survival of 34.3 months with amivantamab-chemotherapy versus 27.9 months with chemotherapy.

The Lancet: New US Medicare pricing policies could reshape global pharmaceutical markets, potentially driving up prices and delaying medicine launches worldwide, study suggests

A new US Medicare pricing policy could reshape global pharmaceutical markets, potentially driving up prices and delaying medicine launches worldwide. The study estimates that Medicare could save $5.2 billion under its initial phase, with savings rising to $21 billion if expanded to all Medicare beneficiaries.

Smartphones could be used to screen for cataracts and other eye problems

Researchers developed a low-cost smartphone attachment to capture diagnostic-quality eye images, which can be reviewed remotely by ophthalmologists. Community health workers and remote ophthalmologists agreed on 96% of cataract diagnoses, challenging the assumption that specialist presence is necessary for accurate screening.

KAIST and KIOM develop a wearable microneedle electroceutical for personalized pain management

Researchers developed a wearable electroceutical platform with microneedle electrodes that deliver stable electrical stimulation while reducing the influence of sweat or dead skin cells. The device can be remotely controlled via smartphone and automatically detaches when skin overheats for enhanced safety.

Phase 1 study supports recommended phase 3 dose for investigational EGFR x HER3 antibody-drug conjugate in EGFR-mutated lung cancer

A Phase 1 study showed the investigational therapy demonstrated a manageable safety profile, with 33.3% of patients achieving objective response at the recommended 2.5mg/kg dose. The treatment was well-tolerated, with no treatment-related deaths and only one patient discontinuing due to an adverse event.

Extended-interval tarlatamab dosing shows consistent activity and safety in previously treated small cell lung cancer

Results from the DeLLphi-309 study suggest that extended-interval dosing regimens of tarlatamab may offer patients greater treatment flexibility while maintaining comparable clinical activity. The study found improved overall survival rates with less frequent dosing schedules, but with similar treatment-emergent adverse event rates.

Study suggests that people with diabetes who are controlling their blood sugar too strictly (within safe limits) could be experiencing less enjoyment in life

A new study suggests that individuals with diabetes who focus on tightly controlling their blood sugar levels may be missing out on enjoyable activities due to the associated burden. Higher glucose variability and better sleep quality on the previous day were associated with improved quality of life on the following day.

Researchers discover rare cortical neurons that can help put the brain to sleep

Researchers have discovered a rare population of neurons in the cortex that can synchronize activity across large areas of the brain and promote sleep. These Sst-Chodl neurons were found to be active during the transition to sleep and could even help drive the process, suggesting that the cortex is not simply passive during sleep.

New disease found that causes night blindness and loss of peripheral vision

A new vision condition, EFEMP1-associated late-onset retinal degeneration (L-ORD), has been discovered, causing slow decline in peripheral vision and night vision loss. The p.Arg140Trp variant in the EFEMP1 gene leads to abnormally thick material building up between eye cells, affecting rod photoreceptors' recovery in darkness.

New findings on information processing in the brain

Researchers have discovered tiny constrictions in dendrite extensions of nerve cells, which may enable local information processing and shape synaptic integration. These constrictions, only a few hundred nanometers wide, occur in various types of neurons and are linked to NMDA receptor activation and learning processes.
