AI Article Synopsis
- The study focused on analyzing poisoning cases in people with dementia, identifying common substances and sources of medication errors.
- A total of 2726 cases were reviewed, with the majority resulting from therapeutic errors, especially involving donepezil and paracetamol, as well as accidental exposures primarily linked to hand sanitizer.
- The findings highlight the need for better strategies to prevent these incidents, particularly since many errors were related to double dosing and mistakes by caregivers.
Article Abstract
Objective: To describe the most common types of poisoning exposures, implicated substances and underlying sources of medication error in people with dementia.
Design: Retrospective analysis of call records from the New South Wales (NSW) Poisons Information Center (PIC).
Setting And Participants: People with dementia who had a poisoning exposure reported to the NSW PIC (Australia's largest PIC).
Methods: A retrospective study was conducted using data from the NSW PIC from July 2014 to July 2019. All calls pertaining to individuals with a reported diagnosis of dementia (Alzheimer's disease or other) or who were taking an antidementia drug were included. Descriptive analysis was performed to characterize poisoning exposures, substances involved, and sources of error.
Results: A total of 2726 cases involving individuals with dementia [mean age = 79.5 (standard deviation 11.0) years; 56.2% female] were reported to the NSW PIC after intentional or unintentional poisoning. Therapeutic errors comprised 1692 (62.1%) of all reported cases followed by accidental exposures which contributed 711 (26.1%). The most common therapeutic substances responsible for therapeutic errors were donepezil (137 cases, 8.1%) and paracetamol (87 cases, 5.1%). The greatest proportion of all accidental exposures was attributed to hand sanitizer (46 cases, 6.5%). Over one-half of therapeutic errors (n = 1021, 60.3%) were linked to double dosing or mistiming of medications, and nursing home or carer errors were implicated in 385 cases (22.8%). Calls were most commonly made by family (n = 1187, 43.5%) and handled at home (n =1444, 53.0%).
Conclusions And Implications: Therapeutic errors and accidental poisonings are of concern in people with dementia. Strategies to reduce these potentially preventable adverse events should be further explored.

Understanding the complex biological process of aging is of great value, especially as it can help develop therapeutics to prolong healthy life. Predicting biological age from gene expression data has shown to be an effective means to quantify aging of a subject, and to identify molecular and cellular biomarkers of aging. A typical approach for estimating biological age, adopted by almost all existing aging clocks, is to train machine learning models only on healthy subjects, but to infer on both healthy and unhealthy subjects.

Background: Respiratory motion during radiotherapy (RT) may reduce the therapeutic effect and increase the dose received by organs at risk. This can be addressed by real-time tracking, where respiration motion prediction is currently required to compensate for system latency in RT systems. Notably, for the prediction of future images in image-guided adaptive RT systems, the use of deep learning has been considered.

Skin aging, characterized by reduced elasticity, wrinkles, and changes in pigmentation, presents significant challenges in the cosmetics industry. Identifying compounds that can help mitigate these effects is crucial to developing effective anti-aging treatments and improving skin health. An advanced analytical approach for identifying skin anti-aging compounds within complex natural mixtures must be developed to achieve this.

Article Synopsis
- A study in Jordan found a 2.4% prevalence of vaccine administration errors (VAEs) during the COVID-19 vaccination campaign, with various types of errors identified, including timing and dosing mistakes.
- Most errors were minor or moderate, and significant contributing factors included healthcare provider issues and higher error rates during peak vaccination times and in the Southern region.
- The findings highlight the need for more research and strategies to address VAEs to ensure effective immunization and patient safety.

Background: The Motricity Index (MI) is a commonly used method of measuring muscle strength in post-stroke hemiparesis. This study aimed to produce the MI Italian version (MI-IT) and assess its reliability in subjects with stroke.
Methods: Phase-1: stepwise approach to MI-IT production and pilot-testing with 10 health professionals to ensure clarity of each item and instructions for administration and scoring.
