Article Abstract

Clinical trial data regarding efficacy and safety of cladribine in MS are limited to young individuals, and the overall risk-benefit profile does not necessarily applies to elderly patients. We investigated effectiveness and safety outcomes in MS patients initiating cladribine at ≥50 years (n=35) and <50 years (n=62), over a median follow-up of 12.4 months. There were no differences in time to evidence of disease activity (HR=0.73, 95%CI=0.18-2.91, p=0.657), post-treatment lymphocyte counts (β=0.24, p=0.825) or occurrence of adverse events (OR=0.84, 95%CI=0.24-2.93, p=0.791) between age groups. Female sex and greater disability were associated with higher risk of adverse events (especially infections). These limited data do not suggest safety concerns regarding use of cladribine in elderly MS.

An aptasensor-based fluorescent signal amplification strategy for highly sensitive detection of mycotoxins.

Anal Methods

September 2025

Key Laboratory of Biorheological Science and Technology of Ministry of Education, College of Bioengineering, Chongqing University, Chongqing 400044, P. R. China.

Aflatoxin B1 (AFB1) is one of the most toxic mycotoxins that pose great health threats to humans. Herein, an aptasensor-based fluorescent signal amplification strategy is developed for the detection of AFB1. Initially, the AFB1 aptamers labelled with carboxyfluorescein (FAM) are adsorbed onto graphene oxide (GO), triggering energy transfer.

Influenza viruses can be aerosolized when slaughtering infected chickens, which increases the risk of zoonotic transmission. We conducted pilot experiments to measure the concentrations of airborne particles <2.5 μm during slaughtering and defeathering of chickens to help identify methods that can minimize workers' exposure to potentially hazardous aerosol particles.

Surgical outcomes from haematoma evacuation for intracerebral haemorrhage in the INTERACT3 study.

Lancet Reg Health West Pac

September 2025

Department of Neurosurgery, West China Hospital, Sichuan University, Chengdu, China.

Background: There is ongoing controversy as to whether surgical intervention to haematoma evacuation benefits patients with acute intracerebral haemorrhage (ICH). This study aimed to evaluate the association of surgical intervention to evacuate the haematoma and 6-month functional outcome in participants of the third Intensive Care Bundle with Blood Pressure Reduction in Acute Cerebral Haemorrhage Trial (INTERACT3).

Methods: This was a secondary analysis of INTERACT3, which enrolled adults (age ≥18 years) spontaneous ICH patients within 6 h after onset.
