ReviewSystematic review of the synergist muscle ablation model for compensatory hypertrophy.
The aim was to evaluate the effectiveness of the experimental synergists muscle ablation model to promote muscle hypertrophy, determine the period of greatest hypertrophy and its influence on muscle fiber types and determine differences in bilateral and unilateral removal to reduce the number of animals used in this model. ⋯ This model differs from other overload models (exercise and training) regarding the characteristics involved in the hypertrophy process (acute) and result in a chronic muscle adaptation with selective regulation and modification of fast-twitch fibers in skeletal muscle. This is an efficient and rapid model for compensatory hypertrophy.

Influence of morbid obesity on physical capacity, knee-related symptoms and overall quality of life: A cross-sectional study.
To evaluate the impact of morbid obesity on physical capacity, joint-related symptoms, and on the overall quality of life. ⋯ Obesity led to significant loss of physical capacity, gait impairment, knee-related symptoms, and a negative impact on the overall quality of life.

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.

Comparative StudyDepression, stress and anxiety in medical students: A cross-sectional comparison between students from different semesters.
To compare the prevalence of anxiety, depression, and stress in medical students from all semesters of a Brazilian medical school and assess their respective associated factors. ⋯ Our findings revealed high levels of depression, anxiety, and stress symptoms in medical students, with marked differences among course semesters. Gender and religiosity appeared to influence the mental health of the medical students.
