Low irisin levels are associated with increased body weight and an adverse metabolic profile.

Objective: To assess whether plasma irisin is associated with anthropometric, body composition, and metabolic parameters according to body mass index.

Methods: A prospective cohort study was conducted at a tertiary referral hospital in Southern Brazil. Patients were divided according to body mass index: Group 1 (body mass index = 18.

Ethical and legal aspects concerning robotic surgery in Brazil.

Robotic surgery is a technological milestone that directly impacts the provision of healthcare services. Procedures that utilize robotics are continuously being developed. In this context, it is important to analyze the distribution of ethical and civil liability among doctors, hospitals, and suppliers of surgical equipment in cases of alleged medical errors or adverse events that may harm patients.

TITANIUM CLIPS FOR CLOSURE OF THE PERITONEAL FLAP DURING LAPAROSCOPIC INGUINAL HERNIA REPAIR.

Background: The laparoscopic approach for inguinal hernia repair has been widely used since its introduction in the 1990s. As a step in the procedure, the surgeon must access the preperitoneal space through an incision in the peritoneum, creating an adequate dissection for mesh placement. At the end of the procedure, the peritoneal flap must be closed to avoid adhesions.

Gastrointestinal emergency care during the COVID-19 pandemic: rapid communication.

Objective: Social distancing during the COVID-19 pandemic has been associated with a decrease in the search for medical care. High-risk patients have avoided hospital environments fearing infection. We hypothesize that there was also a decrease in the search for medical care related to gastrointestinal emergencies.

Preoperative Level of Leptin Can Be a Predictor of Glycemic Control for Patients with Diabetes Undergoing Bariatric Surgery.

Introduction: Bariatric surgery is a first-line treatment for patients with obesity and diabetes. It is uncertain whether leptin has an influence on glycemia in the postoperative period.

Methods: A cohort study of thirty-eight individuals with obesity and diabetes who underwent laparoscopic Roux-en-Y gastric bypass was undertaken.

Elastic Fibers Density: a New Parameter of Improvement of NAFLD in Bariatric Surgery Patients.

Purpose: Obesity is a major risk factor for nonalcoholic fatty liver disease (NAFLD), affecting 25% of the worldwide population. Weight loss through bariatric surgery can improve much of the liver steatosis, inflammation, and fibrosis. However, it is not known whether there is reversal of the elastic fiber deposition process, triggered by hepatic damage and related to worse prognosis.

Are Noninvasive Methods Comparable to Liver Biopsy in Postoperative Patients After Roux-en-Y Gastric Bypass?

Introduction: Transient tissue elastography (TTE) may estimate the degree of hepatic fibrosis in patients with obesity, but the method has restrictions that are mainly related to patients' BMI.

Purpose: To compare the results of the evaluation of hepatic fibrosis by biochemical methods and TTE with those determined by liver biopsy in patients after RYGB.

Methods: This was a cross-sectional study involving patient data, TTE, and liver biopsy 1 year after RYGB.

Collagen I and III in women with diastasis recti.

Objectives: Interest in elucidating the etiology of hernias has encouraged countless studies of musculoaponeurotic structures in individuals with and without hernias. Studies of hernia patients have firmly demonstrated a correlation between hernias and collagen alterations in their fascia. Diastasis recti is an increased width of the abdominal midline that is exclusively composed of interlacing aponeurotic expansions of the anterolateral abdominal muscles.

PERITONEAL ADHESIONS TYPE I, III AND TOTAL COLLAGEN ON POLYPROPYLENE AND COATED POLYPROPYLENE MESHES: EXPERIMENTAL STUDY IN RATS.

Background: Hernia correction is a routinely performed treatment in surgical practice. The improvement of the operative technique and available materials certainly has been a great benefit to the quality of surgical results. The insertion of prostheses for hernia correction is well-founded in the literature, and has become the standard of treatment when this type of disease is discussed.

Early reduction of resting energy expenditure and successful weight loss after Roux-en-Y gastric bypass.

Background: Weight loss and body composition changes after Roux-en-Y gastric bypass (RYGB) may influence resting energy expenditure (REE). The effect of lower REE after the procedure on long-term weight remains to be elucidated.

Objective: To evaluate the effects of RYGB on REE and body composition 6 months after RYGB and to find out whether postsurgery REE affects weight at 12 and 18 months SETTING: Tertiary referral hospital, southern Brazil METHOD: A prospective study involving 30 RYGB patients aged>18 years was performed.

LINEA ALBA COLLAGEN ASSESSMENT IN MORBIDLY OBESE PATIENTS.

Background: The evaluation of collagen in the abdominal wall has been increasingly studied because of the relevance on collagen in the healing process after laparotomy.

Aim: To evaluate the amount of collagen in the linea alba of patients undergoing laparotomic bariatric surgery and comparing with non-obese cadavers.

Methods: Were evaluated 88 samples of aponeurosis from abdominal linea alba of 44 obese patients (obesity group) and 44 non-obese cadavers (control group).

IMPROVEMENT IN OXIDATIVE STRESS AFTER DUODENOJEJUNOSTOMY IN AN EXPERIMENTAL MODEL OF TYPE 2 DIABETES MELLITUS.

Background: Type 2 Diabetes Mellitus is a multifactorial syndrome with severe complications. Oxidative stress is accepted as a causal factor of chronic complications.

Aim: To demonstrate alterations in oxidative stress after metabolic surgery.

Determinants of body weight regulation in humans.

Body weight is regulated by the ability of hypothalamic neurons to orchestrate behavioral, endocrine and autonomic responses via afferent and efferent pathways to the brainstem and the periphery. Weight maintenance requires a balance between energy intake and energy expenditure. Although several components that participate in energy homeostasis have been identified, there is a need to know in more detail their actions as well as their interactions with environmental and psychosocial factors in the development of human obesity.

Laparoscopic splenectomy for isolated splenic sarcoidosis.

Introduction: Sarcoidosis is an inflammatory disease with an unknown etiology. The pulmonary interstitium is mainly involved, with noncaseating granulomas and lymphadenopathy. It is a multisystemic disease, and the differential diagnosis should include infectious, neoplastic, and autoimmune diseases to prevent inappropriate treatment and unnecessary surgery.

[Can videolaparoscopic access be used as routine in splenectomies?].

Background: Laparoscopic splenectomy is an alternative for the treatment of patients undergoing elective splenectomy. One of its main indications is in hematologic diseases non-responsive to pharmacological treatment. Videolaparoscopy presents advantages to patients when compared to laparotomy: less post-operative pain, recovery of the functions of the gastrointestinal tract, better cosmetic results and shorter hospitalization.

Effect of the oral administration of monosodium glutamate during pregnancy and breast-feeding in the offspring of pregnant Wistar rats.

Purpose: Determine the effects of the MSG (monosodium glutamate) in the offspring of pregnant rats through the comparison of the weight, NAL (nasal-anal length) and IL (Index of Lee) at birth and with 21 days of life.

Methods: Pregnant Wistar rats and their offspring were divided into 3 groups: GC, G10 and G20. Each of the groups received 0%, 10% and 20% of MSG, respectively from coupling until the end of the weaning period.

Experimental model of the formation of pelvic adhesions by videolaparoscopic in female rabbits.

Purpose: To verify the frequency of postsurgical pelvic adhesion formation in an experimental animal model using videolaparoscopy.

Methods: Experimental study in a sample of 11 non-pregnant female rabbits, aged 5 to 7 months. After general anesthesia, access to the abdominal cavity was performed by an open puncture technique, with 10mm optics, placing two other 5 mm trochars under direct visualization, in the iliac fossae.
