ReviewBariatric surgery in individuals with liver cirrhosis: A narrative review.
Bariatric surgery has become the gold standard treatment for morbid obesity, but there is no consensus regarding its safety and efficacy among individuals with chronic liver diseases. ⋯ Bariatric surgery is safe and effective in individuals with compensated cirrhosis without significant portal hypertension, but presents higher morbidity. Among candidates to liver transplantation and/or individuals with severe portal hypertension, morbidity and mortality are significantly higher.

Randomized Controlled TrialA prospective randomized trial comparing patent blue and methylene blue for the detection of the sentinel lymph node in breast cancer patients.
Methylene blue is more widely available and less expensive than patent blue, with an apparently lower risk of anaphylaxis. ⋯ Methylene blue performed as well as patent blue in identifying the SLN in breast cancer patients.

Qualitative and quantitative ultrasound assessment of gastric content.
Pulmonary aspiration of the gastric contents is one of the most feared complications in anesthesia. Its prevention depends on preoperative fasting as well as identification of risky patients. A reliable diagnostic tool to assess gastric volume is currently lacking. The aim of this study performed on volunteers was to evaluate the feasibility of ultrasonography to identify qualitative and quantitative gastric content. ⋯ Bedside sonography can determine the nature of gastric content. It is also possible to estimate the difference between an empty gastric antrum and one that has some food in it. Such information may be useful to estimate the risk of aspiration, particularly in situations when prandial status is unknown or uncertain.

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.
