A major advantage of using computerized adaptive testing (CAT) is improved measurement efficiency; better score reliability or mastery decisions can result from targeting item selections to the abilities of examinees. However, this type of engineering solution can result in differential content for different examinees at various levels of ability. This paper empirically demonstrates some of the trade-offs which can occur when content balancing is imposed in CAT forms or conversely, when it is ignored. That is, the content validity of a CAT form can actually change across a score scale when content balancing is ignored. On the other hand, efficiency and score precision can be severely reduced by over specifying content restrictions in a CAT form. The results from two simulation studies are presented as a means of highlighting some of the trade-offs that could occur between content and statistical considerations in CAT form assembly.

Remote monitoring of patients with COPD disease using a tablet system: a randomised crossover study of quality-of-life measurements.
ERJ Open Res
January 2025
Department of Respiratory Medicine and Allergology, COPD Center, Sahlgrenska University Hospital and Department of Internal Medicine and Clinical Nutrition, Institute of Medicine, Sahlgrenska Academy, University of Gothenburg, Gothenburg, Sweden.
Background: Remote patient monitoring (RPM) has been evaluated in COPD, but with varying results. We aimed to evaluate whether a tablet system that monitors disease-related parameters in patients with COPD could influence physical and mental health-related quality of life, compared with usual care (UC).
Methods: 70 patients with Global Initiative for Chronic Obstructive Lung Disease (GOLD) group D COPD (61% women, aged 71±8 years, forced expiratory volume in 1 s % predicted 41±13%, COPD Assessment Test (CAT) 19±7 points) were recruited at the COPD centre in Gothenburg, Sweden, and randomised to a tablet-based RPM system or UC for a 26-week period, after which they crossed over to the alternative management for another 26 weeks.
Phototoxic reaction to oral terbinafine due to Tinea capitis in a child.
Acta Dermatovenerol Croat
November 2024
Prof. Ana Bakija-Konsuo, MD, PhD, Clinic for Dermatovenerology CUTIS, Vukovarska 22, Dubrovnik, Croatia;
We report the case of an 18-month-old boy who developed a phototoxic skin reaction to terbinafine on his scalp, ears, and face in the form of disseminated erythematous plaques, which resembled subacute lupus erythematosus (SCLE) in their clinical presentation. Skin changes appeared a short time after the boy was exposed to sunlight during the period of time when he was treated with oral terbinafine due to Microsporum canis fungal scalp infection. Tinea capitis is a common dermatophyte infection primarily affecting prepubertal children (1).

School of Veterinary Science, Massey University, Palmerston North, New Zealand.
Background: Most veterinary literature examining medication compliance has described the phenomenon in dogs. The evidence available regarding factors affecting cat owner medication compliance is limited.
Objectives: Identify and describe factors associated with cat owners' noncompliance with veterinary recommendations for pet medications, as well as client-reported barriers and aids to administering medications prescribed by primary care veterinarians.
Hypoxia-Responsive Covalent Organic Framework Nanoplatform for Breast-Cancer-Targeted Cocktail Immunotherapy via Triple Therapeutic Switch Mechanisms.
Small

School of Pharmacy, Southwest Medical University, Luzhou, Sichuan, 646000, China.
Covalent organic frameworks (COFs), known for their exceptional in situ encapsulation and precise release capabilities, are emerging as pioneering drug delivery systems. This study introduces a hypoxia-responsive COF designed to encapsulate the chemotherapy drug gambogic acid (GA) in situ. Bimetallic gold-palladium islands were grown on UiO-66-NH (UiO) to form UiO@Au-Pd (UAPi), which were encapsulated with GA through COF membrane formation, resulting in a core-shell structure (UAPiGC).

Background: Digestive disorders are one of the main health problems in suckling piglets. The correct visual identification of feces in suckling piglets is an important tool for the diagnosis of enteric diseases. The aim of the present observational study was to analyze different physicochemical parameters of the feces of suckling piglets aged 0 to 21 days: visual appearance (color and consistency), fecal dry matter (FDM) content and pH.
