Background: The use of cosmetics is rising, and adverse reactions to these products are increasing. In Sweden, the Medical Products Agency (MPA) keeps a voluntary reporting system for such adverse reactions. However, the reporting is sparse, consisting almost only of cases with test-proven allergic contact dermatitis, thus under-reporting the more common irritant reactions.
Objective: The aim of the study was to try to improve the reporting system.
Patients And Methods: Dermatologists at 3 dermatology departments used a structured protocol during the clinical investigation of 151 consecutive patients reporting skin reactions to cosmetics. The protocol included symptoms, signs, affected body site, suspected products, and final diagnosis after patch testing. Based on clinical data and patch test results, a causality assessment for each product was made according to a protocol used at the MPA.
Results: Allergic contact dermatitis was found in 28% of the patients, and irritant reactions were equally common at 27%.
Conclusions: Using this structured protocol, the cases of irritant dermatitis were also reported, and it is recommended that such a protocol is used as a standard to improve the reporting of adverse reactions to skin care products.

Shaping the structural dynamics of motor learning through cueing during sleep.

Enhancing the retention of recent memory traces through sleep reactivation is possible via Targeted Memory Reactivation (TMR), involving cueing learned material during post-training sleep. Evidence indicates detectable short-term microstructural changes in the brain within an hour after motor sequence learning, and post-training sleep is believed to contribute to the consolidation of these motor memories, potentially leading to enduring microstructural changes. In this study, we explored how TMR during post-training sleep affects performance gains and delayed microstructural remodeling, using both standard Diffusion Tensor Imaging (DTI) and advanced Neurite Orientation Dispersion & Density Imaging (NODDI).

Here, we report on methods for late-stage peptide diversification through palladium-catalyzed site-selective C(sp)-H amination of tryptophan residues at the C4 position, utilizing tryptophan-amine cross-links. Our strategy enables practical access to C-N bonds, facilitating the construction of cyclopeptides via late-stage cyclodimerization of structurally complex peptides, which poses significant challenges for organic synthesis. The synthetic utility of this protocol is demonstrated through the synthesis of 30- to 38-membered macrocyclic peptides.

Objective: This study was undertaken to describe incidence and distribution of seizures, etiologies, and epilepsy syndromes in the general child and youth population, using the current International League Against Epilepsy (ILAE) classifications.
Methods: The study platform is the Norwegian Mother, Father, and Child Cohort Study (MoBa). Epilepsy cases were identified through registry linkages facilitated by Norway's universal health care system and mandatory reporting to the Norwegian Patient Registry.

Background: There is no strong evidence demonstrating whether or not aerobic exercise in conjunction with resistance exercise improves metabolic diabetes markers in postmenopausal women.
Objective: To evaluate the effect of aerobic exercise and resistance training on metabolic markers in postmenopausal women with type 2 diabetes mellitus (T2DM) by means of a systematic review and meta-analysis.
Methods: The searches were completed using EMBASE, MEDLINE/PubMed, Scopus and Web of Science databases.
Decreased Physical Activity and Endurance Capacity in Patients Qualified for Haematopoietic Stem Cell Transplantation (HSCT).
J Clin Med
December 2024
Department of Physiotherapy, Wroclaw University of Health and Sport Sciences, 51-612 Wroclaw, Poland.
Haematological malignancies and their treatment regimens often lead to various complications that impair patients' physical functioning. This study aimed to assess the level of physical activity and exercise capacity in patients with haematological malignancies who were qualified for haematopoietic stem cell transplantation (HSCT). A prospective, single-centre study was conducted on patients with haematological malignancies qualified for HSCT (study group, = 103) and a cohort of healthy volunteers (reference group, = 100).
