Waist-to-height ratio cut-off points to predict obesity in adolescents and associa-tion with inflammatory markers.

Introduction: obesity increases inflammatory molecules and cardiovascular risk even in young populations. New indicators are being investigated, including the waist-to-height ratio (WHtR) to predict obesity and the relationship with inflammatory markers in childhood and adolescence. Objective: to identify the cut-off points of the WHtR to determine obesity and its association with inflammatory markers in adolescents in São Luís, state of Maranhão, Brazil.

Specific and aspecific immune responsiveness in lung cancer patients: cutaneous delayed hypersensitivity reactions to a lung cancer-associated antigen.

The ability of a lung cancer-associated antigen (LCAA) to provoke specific cutaneous delayed-hypersensitivity reactions has been studied on a group of 59 lung cancer patients. Biological activity of LCAA, monitored by skin testing, was demonstrated in 32% (17 of 53) of lung cancer patients, in 48.0% with limited disease, and in 17.
