Inhaling Penehyclidine to Prevent Perioperative Respiratory Adverse Events in Children at Risk Undergoing Sevoflurane Anesthesia

This randomized controlled study is to evaluate the effectiveness of inhaling penehyclidine hydrochloride in reducing perioperative respiratory adverse events in children at risk undergoing minor elective surgery.

Evaluation of the Relationship Between Fall Risk, Muscle Strength, and Anticholinergic Burden in Geriatric Patients Presenting to the Emergency Department

Falls are common among older adults and can lead to serious injury. This study looks at whether taking many medications (polypharmacy), the anticholinergic burden of those medications (a measure of side effects that can affect memory, balance, and muscle function), and sarcopenia (age-related loss of muscle mass and strength) are related to fall risk in older adults visiting the emergency department. Patients aged 65 and older who come to the emergency department will be invited to take part. With their consent, researchers will review the medications they are taking and calculate an anticholinergic burden score. Researchers will also measure the patients' hand grip strength and use ultrasound to measure the thickness of the quadriceps muscle in the thigh, both of which are used to assess muscle health. Information about the patients' history of falls in the past year, hospital stays, and other health conditions will also be collected. All measurements are non-invasive, are already used in routine clinical practice, and are performed only once during the emergency department visit. No experimental treatment or medication will be given as part of this study. The goal of this study is to understand how polypharmacy, anticholinergic burden, and sarcopenia relate to fall risk, both individually and together, so that older adults at higher risk of falling can be identified earlier and offered appropriate prevention strategies.
