July 2022
Article Synopsis
- Surgical treatment for obesity, particularly through gastric bypass, significantly affects respiratory mechanics in patients.
- This study compares respiratory muscle strength between patients undergoing bariatric surgery via laparotomy and laparoscopy during their hospital stay.
- Findings indicate that laparotomy patients experience greater reductions in respiratory strength and more severe pain compared to those who had laparoscopic surgery, with no return to baseline strength in the former group by discharge.
Weight regain is a multifactorial condition that affects many patients following bariatric surgery. The purpose of the paper is to review the multidisciplinary approach for the management of weight regain. We performed a search in current clinical evidence regarding the causes, consequences, and treatments of weight regain.

The goal of the study was to assess administration of remifentanil combined with propofol regarding the effects of the drug association during sedation and recovery for patients submitted to upper gastrointestinal diagnostic endoscopy.
Method: One hundred and five patients were assessed, randomly divided into three groups of 35 patients.
Purpose: Propose the systematization of nutritional care in the endoscopic treatment of obesity.
Method: This is a bibliographical review, since the initial proposal was a systematic review. This method became unfeasible due to the inexistence of studies that address this theme.
Background: The Bariatric Plate Model (BPM) may be an adequate form of nutritional guideline after obesity surgery.
Aim: Create a food guide, based on the Plate Model for nutritional education of bariatric patients.
Method: The Plate Model2 was revised from a model initially suggested for dyslipidemic and hypertensive patients to a new objective: adaptation to bariatric patient who needs effective long-term nutritional education.
Background: Bariatric surgery is considered the best treatment option for patients with obesity who are classed as high risk for thromboembolic events.
Objectives: To compare two different doses of low weight molecular heparin (LWMH) for prevention of deep venous thrombosis (DVT) in candidates for bariatric surgery, in terms of DVT risk, abnormal anti-Xa levels, and preoperative and/or postoperative bleeding.
Methods: A cross-sectional comparative study of bariatric surgery patients divided into two groups given different doses of LWMH; 40 mg of LWMH (control group, CG) and 80 mg of LWMH (study group, SG), both evaluated by vascular ultrasonography (VU) and according to the results of PTT, PT, platelets, and anti-Xa factor assays.
Background: Bariatric surgery is deemed one of the most effective procedures for the treatment of obesity and it aims at the reduction and maintenance of weight loss in long term, as the control of the related comorbidities.
Aim: Quantify the occurrence of alterations of the gastrointestinal tract, suggestive signs of nutritional deficiencies and the use of supplements in a group of women undergoing bariatric surgery.
Methods: The sample consisted of women aged 20-65 years submitted to Roux-en-Y gastric bypass with monitoring equal to or higher than 24 months.
Background: The bariatric surgery may cause some nutritional deficiencies.
Aim: To compare the serum levels of biochemical markers, in iimmediate post-surgical patients who were submitted to bariatric surgery.
Methods: Non-concurrent prospective cross-sectional study.
Background And Objectives: The introduction of propofol (2,6-diisopropylphenol) as a sedative agent has transformed the area of sedation for endoscopic procedures. However, a major drawback of sedation with the use of propofol is its high incidence of injection pain. The most widely used technique in reducing propofol injection pain is through the association of other drugs.

Secondary hyperparathyroidism is one such complications that leads to increased parathyroid hormone levels due to a decrease in calcium and vitamin D, which may compromise bone health.
Aim: To compare calcium carbonate and calcium citrate in the treatment of secondary hyperparathyroidism.

View Article and Find Full Text PDFBackground: Bariatric surgery is effective treatment for weight loss, but demand continuous nutritional care and physical activity. They regain weight happens with inadequate diets, physical inactivity and high alcohol consumption.
Aim: To investigate in patients undergoing Roux-Y-of gastroplasty weight regain, nutritional deficiencies, candidates for the treatment with endoscopic argon plasma, the diameter of the gastrojejunostomy and the size of the gastric pouch at the time of treatment with plasma.
Purpose: To evaluate the influence of the cyclosporine in liver regeneration in rats submitted to an experimental model of 70% hepatectomy.
Methods: Forty male rats were randomly divided in four subgroups (C.24h, C.
Background: Bariatric surgery, especially Roux-en-Y gastric bypass is an effective treatment for refractory morbid obesity, causing the loss of 75% of initial excess weight. After the surgery, however, weight regain can occur in 10-20% of cases. To help, endoscopic argon plasma coagulation (APC) is used to reduce the anastomotic diameter.
View Article and Find Full Text PDFObjective: To evaluate the influence of sirolimus on liver regeneration triggered by resection of 70% of the liver of adult rats.
Methods: we used 40 Wistar rats randomly divided into two groups (study and control), each group was divided into two equal subgroups according to the day of death (24 hours and seven days). Sirolimus was administered at a dose of 1mg/kg in the study group and the control group was given 1 ml of saline.
Background: The failure of approximately 20 % of obese patients who undergo Roux-en-Y gastric bypass (RYGB) to maintain weight loss over the following 18-24 months is related to the surgical procedure, to the patient, or both. Although the underlying mechanisms are uncertain, one factor that has been postulated is the dilation of the gastrojejunal anastomosis. The objective was to evaluate the safety and efficacy of the serial use of argon plasma coagulation (APC) in reducing the diameter of the dilated gastrojejunal anastomosis and post-RYGB weight regain.

Methods: Forty Wistar adult rats, weighing 510.08 + 11.
Objective: To compare safety and efficacy of propofol with midazolam for deep sedation in the colonoscopy.
Methods: In a prospective way, 66 patients underwent colonoscopy--50 patients received propofol in an average dose of 3,25 mgxkg-1 and 16 patients (control group) received midazolam with total average dose of 2,05 mgxkg-1. The dose of medication was titrated according to patient need.
Objective: Identify prognostic factors related to treatment failure of blunt splenic injuries managed by non surgical treatment (NST).
Methods: Fifty six adult patients submitted to NST were prospectively studied. The injuries were diagnosed by computed axial tomography scan and classified according to AAST (American Association for Surgery of Trauma) criteria.
Objective: To establish the ideal power to be employed in order to get the effective ablation and the lowest rate of symptoms at argon plasma thermocoagulation in Barrett's esophagus (BE).
Methods: Twenty-eight asymptomatic patients with BE, were randomly divided in two groups of different ablation powers, 50W or 70W. After endoscopic ablation and biopsies from the treated area for histological analyses, symptoms were evaluated through a questionnaire answered by phone.
Background: Wound contractures can cause severe deformities and disabilities. Recent studies have suggested that leukotriene receptor antagonists have an inhibitory effect on the healing contraction process. This study aimed to evaluate the influence of the leukotriene inhibitor montelukast on the cutaneous healing process and the wound contraction phenomenon in rats.
