Resistance Management for Cancer: Lessons from Farmers.

One of the main reasons we have not been able to cure cancers is that treatments select for drug-resistant cells. Pest managers face similar challenges with pesticides selecting for pesticide-resistant insects, resulting in similar mechanisms of resistance. Pest managers have developed 10 principles that could be translated to controlling cancers: (i) prevent onset, (ii) monitor continuously, (iii) identify thresholds below which there will be no intervention, (iv) change interventions in response to burden, (v) preferentially select nonchemical control methods, (vi) use target-specific drugs, (vii) use the lowest effective dose, (viii) reduce cross-resistance, (ix) evaluate success based on long-term management, and (x) forecast growth and response.

Segmented sleep in a nonelectric, small-scale agricultural society in Madagascar.

Objectives: We studied sleep in a rural population in Madagascar to (i) characterize sleep in an equatorial small-scale agricultural population without electricity, (ii) assess whether sleep is linked to noise levels in a dense population, and (iii) examine the effects of experimentally introduced artificial light on sleep timing.

Methods: Using actigraphy, sleep-wake patterns were analyzed for both daytime napping and nighttime wakefulness in 21 participants for a sum total of 292 days. Functional linear modeling was used to characterize 24-h time-averaged circadian patterns and to investigate the effect of experimentally introduced mobile field lights on sleep timing.

[Breast implant-associated anaplastic large cell lymphoma. Case report of an undiagnosed form, management and reconstruction (ALCL)].

Breast implant-associated anaplastic large cell lymphoma (ALCL) is an extremely rare disease. Is a new nosologic entity with a multifactorial origin and a wide occurrence delay after breast implantation. This article reports the case of a 60 years old patient with a progressive swelling of the right breast after aesthetic breast implants.
