Malaria parasite prevalence in Sub-Saharan African migrants screened in Sweden: a cross-sectional study.

Background: Asymptomatic infections with malaria parasites are common in populations in endemic areas. These infections may persist in migrants after arrival in a non-endemic area. Screening to find and clear these infections is generally not implemented in non-endemic countries, despite a potential negative health impact.

Divergent gene regulation and growth effects by NF-kappa B in epithelial and mesenchymal cells of human skin.

NF-kappa B regulates normal and pathological processes, including neoplasia, in a tissue-context-dependent manner. In skin, NF-kappa B is implicated in epidermal homeostasis as well as in the pathogenesis of squamous cell carcinoma; however, its function in the underlying mesenchymal dermis has been unclear. To gain insight into NF-kappa B roles in these two adjacent cutaneous tissue compartments, NF-kappa B effects on expression of 12 435 genes were determined in epidermal keratinocytes and dermal fibroblasts.

Factors associated with assault-related firearm injuries in male adolescents.

Purpose: To identify factors associated with an increased prevalence of assault-related firearm injuries in male adolescents.

Methods: This study is a retrospective comparison of two samples of adolescent males from the same geographic localities regarding their involvement in the juvenile justice system (court involvement) and injury status (current or prior firearm injury at the time of the study). The subjects included adolescent male patients admitted to an urban, Level I trauma center for assault-related firearm injuries (court-involved and noncourt- involved, n = 65); and incarcerated juvenile offenders (prior firearm injury and no known firearm injury, n = 267).
