Background: Obesity is currently considered a public health problem. Bariatric procedures have become an important part of obesity management and, consequently, the number of male patients seeking post-bariatric reconstructive procedures have increased. Therefore, the clinical approach and understanding of the body contour of this population have become more relevant. The goal of post-bariatric reconstruction is to enhance the male silhouette through removal of skin and adipose tissue excess, and abdominal rectus diastasis repair. Material and Methods: We conducted a retrospective study at the Plastic and Reconstructive Surgery Department of the National Medical Center “20 de Noviembre”. All male patients referred to our department to start a post-bariatric reconstruction protocol from January 2018 to December 2022 were included in this study. Results: In total, 15 patients who underwent corporal contouring procedures were included;median age was 49.2 years with minimum of 33 years, and a maximum of 57 years. Median Body mass index was 28.4 kg/m2 with minimum of 22 kg/m2 and maximum of 38 kg/m2. All patients were treated 18 months after their bariatric surgery. All patients underwent an abdominoplasty as a body contouring procedure. 4 (26.7%) patients presented complications related to the surgery. Conclusion: We described a comprehensive and systematic approach to massive weight loss for male patients, suggesting an abdominal marking based on the patient’s clinical features and the expected results avoiding feminization of the abdominal body contour.

Obesity is a significant and escalating health issue both in Brazil and globally, with over 650 million overweight adults worldwide. The treatment of obesity can be performed clinically, endoscopically or surgically;surgical treatment proves to be safe and more effective in terms of weight loss and long-term maintenance. Objective: This study aimed to monitor the progress of weight loss and comorbidity control in patients undergoing sleeve gastrectomy with duodenal bipartition. Methods: This pilot project involved 8 patients divided into 2 arms. In the first arm, patients underwent sleeve gastrectomy with Roux-en-Y duodenoileal transit bipartition (S-RYDITB), while in the second arm, patients underwent sleeve gastrectomy with Roux-en-Y duodenojejunal transit bipartition (S-RYDJTB). Both procedures involved Roux-en-Y reconstruction without duodenal exclusion. In S-RYDITB, the duodenal-ileal anastomosis was performed 300 cm from the ileocecal valve (ICV), creating a 250 cm common channel and a 50 cm alimentary channel. In S-RYDJTB, a biliopancreatic loop was created 200 cm from the angle of Treitz, with a 1 m alimentary channel. Results: Five patients underwent the procedures, with one undergoing S-RYDITB and four undergoing S-RYDJTB. No adverse events such as hospitalizations, readmissions, reoperations, fistulas, bleeding, pulmonary embolism, diarrhea, dumping syndrome, or hypoglycemia occurred during the study period. The mean length of hospital stay was 2 days. The average BMI decreased from 37.27 kg/m2 preoperatively to 29.48 kg/m2 after 6 months. The significant percentage of weight loss was 21.22%, with excess weight loss of 63.6%. Ninety-five percent remission of comorbidities, including hypercholesterolemia, hypertriglyceridemia, diabetes, hypertension, steatosis, and pre-diabetes. Two patients underwent sleeve gastrectomy with duodenal bipartition using a single anastomosis. Conclusion: Duodenal switch surgery has gained worldwide recog

By combining ab initio calculations and experiments, we demonstrate how the band gap of the transition metal trichalcogenide TiS3 can be modified by inducing tensile or compressive strain. In addition, using our calculations, we predicted that the material would exhibit a transition from a direct to an indirect band gap upon application of a compressive strain in the direction of easy electrical transport. The ability to control the band gap and its nature could have a significant impact on the use of TiS3 for optical applications. We go on to verify our prediction via optical absorption experiments that demonstrate a band gap increase of up to 9% （from 0.99 to 1.08 eV） upon application of tensile stress along the easy transport direction.

This experiment aimed to evaluate the effect of calcium salts of linseed oil (rich in alpha-linolenic acid (ALA, C18:3n-3) on metabolic and reproductive traits in high-producing dairy cows under grazing. Thirty-six Holstein dairy cows were randomly assigned, in a complete block design, to receive ALA supplementation (0.85 kg∙day−1 of calcium salts of linseed oil) or to remain as untreated control (CON). The concentrate was formulated to offer the same amount of energy across treatments (CON cows received an extra kg of corn to compensate for the higher energy density of ALA treatment). A PMR + Alfalfa pasture was offered to all cows at the same time. A fixed time artiﬁcial insemination (FTAI) at 80 DIM, preceded by a Presynch plus Ovsynch protocol was implemented for the first service and later, on return to estrus, heat detection and artiﬁcial insemination (AI) were performed. Pregnancy diagnosis was checked at 30, 42, 60, and 90 d after AI. Blood and milk samples were taken biweekly. Treatment affected plasma cholesterol concentration (160.36 vs. 186.70 mg∙dl−1, p = 0.03, for ALA and CON, respectively) and on size of corpus luteum (CL, 17.6 vs. 13.7 mm, p = 0.02, for ALA and CON, respectively). Supplementation tended (p = 0.136) to increase conception rate by 200 DIM (81.69% vs. 55.43% in ALA and CON cows, respectively). However, treatment had no effect (p > 0.05) on body weight (BW), body condition score (BCS), and circulating levels of beta-hydroxybutyrate (BHBA), glucose, insulin, growth hormone (GH) and insulin-like growth factor (IGF-I). Our results suggest that supplementation with calcium salts of linseed oil could enhance ovarian function without affecting energy metabolism in early lactation dairy cows.

Iron-Deficiency Anemia Management in Gynecological Surgery: A Review of Current Evidence and Best Practices

引用

Open Journal of Obstetrics and Gynecology 2024年第8期14卷 1223-1241页

Purpose: Due to the high prevalence of iron deficiency anemia in women undergoing gynecological surgeries and its association with worse postoperative results, it is necessary to identify and treat anemia preoperatively. However, although anemia and iron deficiency are significant global health problems, there are still disparities in the recognition and implementation of “Patient Blood Management” (PBM) as a comprehensive approach to mitigating the risks associated with these diseases. The purpose of the study is to review best practices for the treatment of anemia based on the Enhanced Recovery After Surgery (ERAS) protocol and PBM recommendations. Methods: This study reviewed the literature on preoperative iron deficiency anemia in patients undergoing gynecological surgery. We identified references through searches in PubMed using relevant search terms. Results: Among the various strategies used in PBM, perhaps the most important is the early detection and management of anemia. In gynecological surgery, there are several approaches to reducing perioperative blood loss, highlighting the use of gonadotropin-releasing hormone (GnRH) agonists (aGnRh) and antifibrinolytics. Oral and intravenous iron supplementation can be performed in addition to blood transfusion to treat anemia. Conclusion: Addressing preoperative and postoperative anemia through systematic correction, following the guidelines of the ERAS protocol and PBM guidelines, is essential to improving perioperative outcomes in women undergoing gynecological surgery.

China Ocean Engineering 2014年第5期28卷 687-700页

作者： Flávio Medeiros SEIBT eduardo Costa COUTO Elizaldo Domingues dos SANTOS Liércio André ISOLDI Luiz Alberto Oliveira ROCHA Paulo roberto de Freitas TEIXEIRA Graduate Program of Ocean Engineering Universidade Federal do Rio Grande96203-900 Rio Grande RS Brazil Mechanical Engineering Department Universidade Federal do Rio Grande do Sul90050-170 Porto Alegre RS Brazil

The growing search for clean and renewable energy sources has given rise to the studies of exploring sea wave energy. This paper is concerned with the numerical evaluation of the main operational principle of a submerged plate employed for the conversion of wave energy into electrical one. The numerical model used to solve the conservation equations of mass, momentum and transport of volume fraction is based on the finite volume method （FVM）. In order to tackle with the flow of mixture of air-water and its interaction with the device, the multiphase model volume of fluid （VOF） is employed. The purpose of this study is the evaluation of a numerical model for improvement of the knowledge about the submerged plate wave energy converter, as well as the investigation of the effect of the distance from the plate to the bottom of the sea （HP） on the performance of the converter. The simulations for several distances of the plate from the seabed show that the optimal efficiency is 64%, which is obtained for HP=0.53 m （88% of the depth）. This efficiency is 17% larger than that found in the worst case （HP=0.46 m, 77% of the depth）.

Background: Intussusception is defined as a telescoping of a proximal gastrointestinal segment with its mesentery to a distal one, only 5% occur in adults and in colon the probability that it is caused by a malignant disease is up to 65%. Only 1% occurs in a retrograde manner, the rest occur in an anterograde manner. Aim: Describe the clinical presentation of an intussusception in the adult patient as well as its most frequent causes and possible complications that influence decision making for a definitive treatment. Case Presentation: A 66-year-old woman diagnosed with colon adenocarcinoma who underwent elective transverse colectomy and colonic anastomosis with an incidental finding of a transverse colon tumor in a retrograde intussusception was studied. Conclusion: In any adult patient with an intussusception especially in colon a neoplasia should be suspected and the affected segment should be resected without being reduced due to the risk of perforation and tumor dissemination.
