Absorbed doses to fingernails and organs were calculated for a set of homogenous external gamma-ray irradiation geometries in air. The doses were obtained by stochastic modeling of the ionizing particle transport (Monte Carlo method) for a mathematical human phantom with arms and hands placed loosely along the sides of the body. The resulting dose conversion factors for absorbed doses in fingernails can be used to assess the dose distribution and magnitude in practical dose reconstruction problems. For purposes of estimating dose in a large population exposed to radiation in order to triage people for treatment of acute radiation syndrome, the calculated data for a range of energies having a width of from 0.05 to 3.5 MeV were used to convert absorbed doses in fingernails to corresponding doses in organs and the whole body as well as the effective dose. Doses were assessed based on assumed rates of radioactive fallout at different time periods following a nuclear explosion.

Introduction: Psoriasis in high-impact areas, including the scalp, nails, palms, and soles, can disproportionately impair patient quality of life. Here, we evaluate the 2-year efficacy of bimekizumab treatment in patients with moderate to severe plaque psoriasis in post hoc analyses of five phase 3/3b trials.
Methods: High-impact area efficacy data were pooled through 2 years across five phase 3/3b trials: BE VIVID, BE READY, BE SURE, their ongoing open-label extension (OLE) BE BRIGHT, and BE RADIANT (including its double-blinded treatment period and the first year of its OLE).

Introduction: The aging population is associated with increased osteoporosis and risk of hip fractures. Cognitive decline has recorded exponential increases in the last decades, with the rise in life expectancy.
Material And Methods: We conducted a prospective study on 65 patients over 65 years old associated with dementia and hip fractures.

Lichen planus (LP) is an inflammatory autoimmune mucocutaneous disease with different forms and presentations. It mainly affects the skin and oral mucosa but could also affect genital mucosa, nails, hair, and, rarely, the larynx and esophagus. Since the start of the COVID-19 era, multiple cutaneous manifestations related to SARS-CoV-2 infection or vaccination have been reported.

Welding activities are known to expose workers to metal fumes, but few studies have focused on assessing the internal exposure of apprentices in learning environments. This study aimed at determining internal doses of metals in apprentices performing gas metal arc welding (GMAW) during their training course. A total of 85 apprentice welders were assessed, and multi-elements were measured in urine, hair, fingernail, and toenail samples collected at the beginning of the program, and at the beginning and end of GMAW practical training.
