Patient satisfaction, needs, and preferences concerning information dispensation at the emergency department: a cross-sectional observational study.

Background: Patient satisfaction is an important indicator of emergency care quality and has been associated with information dispensation at the emergency department (ED). Optimal information dispensation could improve patient experience and expectations. Knowing what kind of information patients want to receive and the preferred way of information dispensation are essential to optimize information delivery at the ED.

Surgical treatment of rib fracture nonunion: A single center experience.

Introduction: In contrast to the emerging evidence on the operative treatment of flail chest, there is a paucity of literature on the surgical treatment of rib fracture nonunion. The purpose of this study was to describe our standardized approach and report the outcome (e.g.

Effect of eicosapentaenoic acid, an omega-3 polyunsaturated fatty acid, on UVR-related cancer risk in humans. An assessment of early genotoxic markers.

Dietary omega-3 polyunsaturated fatty acids (omega-3 PUFAs) protect against photocarcinogenesis in animals, but prospective human studies are scarce. The mechanism(s) underlying the photoprotection are uncertain, although omega-3 PUFAs may influence oxidative stress. We examined the effect of supplementation on a range of indicators of ultraviolet radiation (UVR)-induced DNA damage in humans, and assessed effect on basal and post-UVR oxidative status.

Monitoring for DNA damage of humans occupationally exposed to methyl bromide.

Background: Methyl bromide (MeBr) is a methylating agent, weak mutagen and possible animal carcinogen. A molecular epidemiological study to examine human exposure to, and consequent DNA damage by MeBr was conducted in an area where this agent is used extensively for soil sterilisation in greenhouses.

Materials And Methods: During the first part of the study, blood samples were collected from 21 persons within 24 hours after use of MeBr for greenhouse sterilisation, as well as from 19 non-exposed subjects.

Melanin offers protection against induction of cyclobutane pyrimidine dimers and 6-4 photoproducts by UVB in cultured human melanocytes.

The goal of this investigation was to correlate the melanin content in human pigmentary cells with the generation of UVB-induced photoproducts and to examine the relationship between the melanin content and the removal of the photoproducts. Cultured melanocytes from light-skinned individuals synthesized less melanin and produced more cyclobutane pyrimidine dimers and 6-4 photoproducts upon UVB exposure than did melanocytes from black skin. Tyrosine-stimulated melanogenesis provided protection against DNA damage in both cell types.
