Gastric electrical stimulation (GES) has been proposed as a promising therapeutic option in treating obesity for 20 years. Currently, the available device of GES cannot meet the clinical needs. The purpose of this study is to verify the effect of a new type of adjustable gastric electrical stimulator in reducing food intake and body weight. ⋯ Food intake and body weight of dogs are significantly reduced by adjustable GES. Individual parameters and resistance during GES are required to be considered. The new adjustable device may have good prospects of clinical application for obesity.

The consequences of obesity include musculoskeletal pain and its influence on a person's social, personal, and professional life, which is a great challenge for the multidisciplinary team in the treatment of obesity. The objective of this work was to evaluate musculoskeletal pain in the work activities of obese individuals. ⋯ Musculoskeletal pain was very related to obese individuals who participated in this study, and in the majority cases, execution of the work activities of these persons was impeded. This indicates a need for further studies that address this subject to better attend to and intervene in the health of this population.

Multicenter Study
Predictive performance of the STOP-Bang score for identifying obstructive sleep apnea in obese patients.
The loud Snoring, Tiredness, Observed apnea, high blood Pressure (STOP)-Body mass index (BMI), Age, Neck circumference, and gender (Bang) questionnaire is a validated screening tool for identifying obstructive sleep apnea in surgical patients. However, the predictive performance of the STOP-Bang score in obese and morbidly obese patients remains unknown. ⋯ The STOP-Bang score was validated in the obese and morbidly obese surgical patients. For identifying severe OSA, a STOP-Bang score of 4 has high sensitivity of 88 %. For confirming severe OSA, a score of 6 is more specific.

Comparative Study
Gender-related difference in postoperative pain after laparoscopic Roux-En-Y gastric bypass in morbidly obese patients.
Some evidence exist to suggest that women experience more pain and require more medication than men to achieve a similar state of analgesia. However, this was not studied in morbidly obese patients. The study evaluates the effect of gender on postoperative pain and analgesic consumption in the first 24 h in morbidly obese patients who undergo laparoscopic Roux-En-Y gastric bypass surgery (RYNGPB). ⋯ Following PACU discharge, there was no gender difference in pain scores or analgesic consumption. Pethidine consumption in male patients during the first day was 97.8 ± 35.1 versus 98.1 ± 61.6 mg among female patients, P = 0.9729. Female patients had higher initial pain score and morphine consumption than men in the immediate postoperative period, but that difference disappeared after discharge from PACU.

Observational Study
Morbid obesity and optimization of preoperative fluid therapy.
Preoperative venous return (VR) optimization and adequate blood volume is essential in management of morbidly obese patients (MO) in order to avoid perioperative circulatory instability. In this study, all subjects underwent a preoperative 3-week preparation by rapid-weight-loss-diet (RWL) as part of their treatment program for bariatric surgery. ⋯ The IBW-based volume challenge regime was found to be suitable for preoperative rehydration of RWL-prepared MO. Most of the patients were volume responders. Preoperative state of VR was not associated with volume responsiveness. IBW estimates and appropriate monitoring avoids potential hyperhydration in MO. For VC assessment, conventional Doppler indices were found to be more suitable compared to tissue Doppler, giving sufficient information on pressure-volume correlation of the left ventricle in morbidly obese.
