Autophagy is a survival pathway wherein non-functional proteins and organelles are degraded in lysosomes for recycling and energy production. Therefore, autophagy is fundamental for the maintenance of cell viability, acting as a quality control process that prevents the accumulation of unnecessary structures and oxidative stress. ⋯ For instance, in vitro and animal and human studies indicate that autophagy dysfunction in bone cells is associated with the onset of bone diseases such as osteoporosis. This review had the purpose of discussing the issue to confirm whether a relationship between autophagy dysfunction and osteoporosis exits.

Factors related to non-adherence to mammography in a city of the Brazilian Amazonian area: A population-based study.
To assess the prevalence of mammography use and factors related to non-adherence in Boa Vista, capital of Roraima, Brazil. ⋯ Adherence to mammography is unsatisfactory in Boa Vista, Roraima, and has a predominantly opportunistic character. Low educational level is confirmed as an independent risk factor, but belonging to a family that receives government assistance can be interpreted as a social marker of families and/or areas lacking of government intervention to increase access to breast cancer control programs.

ReviewThe role of oxidative stress on the pathophysiology of metabolic syndrome.
Metabolic syndrome (MetS) has a high prevalence around the world. Considering the components used to classify MetS, it is clear that it is closely related to obesity. These two conditions begin with an increase in abdominal adipose tissue, which is metabolically more active, containing a greater amount of resident macrophages compared to other fat deposits. ⋯ One way to block the effects of oxidative stress would be through the antioxidant defense system, which offsets the excess free radicals. It is known that individuals with metabolic syndrome and obesity have high consumption of fats and sugars originated from processed foods containing high levels of sodium as well as low intake of fruits and vegetables, thus maintaining a state of oxidative stress, that can speed up the onset of MetS. Healthy eating habits could prevent or delay MetS by adding antioxidant-rich foods into the diet.
