Excessive accumulation of white adipose tissue leads to obesity and its associated metabolic health consequences such as type 2 diabetes and cardiovascular disease. Several approaches to treat or prevent obesity including public health interventions, surgical weight loss, and pharmacological approaches to reduce caloric intake have failed to substantially modify the increasing prevalence of obesity. The (re-)discovery of active brown adipose tissue (BAT) in adult humans approximately 15 years ago led to a resurgence in research into whether BAT activation could be a novel therapy for the treatment of obesity. Upon cold stimulus, BAT activates and generates heat to maintain body temperature, thus increasing energy expenditure. Activation of BAT may provide a unique opportunity to increase energy expenditure without the need for exercise. However, much of the underlying mechanisms surrounding BAT activation are still being elucidated and the effectiveness of BAT as a therapeutic target has not been realised. Research is ongoing to determine how best to expand BAT mass and activate existing BAT; approaches include cold exposure, pharmacological stimulation using sympathomimetics, browning agents that induce formation of thermogenic beige adipocytes in white adipose depots, and the identification of factors secreted by BAT with therapeutic potential. In this review, we discuss the caloric capacity and other metabolic benefits from BAT activation in humans and the role of metabolic tissues such as skeletal muscle in increasing energy expenditure. We discuss the potential of current approaches and the challenges of BAT activation as a novel strategy to treat obesity and metabolic disorders.<br><b>Introduction</b> Fibroadenomas are one of the most common benign tumors of the breast in the adolescent females accounting for about 2/3^rd of all the breast lumps and more than half of all the biopsied breast lesions. They come into being due to overgrowth of glandular tissue under the influence of hormonal changes that the girls undergo at the time of puberty. Due to the wide prevalence of fibroadenomas and the psychosocial morbidity associated with the finding of a breast mass, it is imperative for physicians treating adolescent patients to be thoroughly familiar and updated with this disease. CWI12 <br><b>Aim</b> The article aims at providing a brief review of the classification, presentation, diagnosis, and update on the management of breast fibroadenomas on the basis of recent literature.<b>Introduction</b> Assessment of exercise tolerance (ET) plays an important role in qualifications for treatment and rehabilitation. <br><b>Aim </b>The aim of the study was to assess ET in patients before and after inguinal hernia operations with Lichtenstein method. <br><b>Material and methods</b> The cohort study included men with inguinal hernia divided into the study group (SG) (n = 50) and control (CG) (n = 50) undergone the Lichtenstein surgery. Patients from the SG met the criterion of coexistence of cardiovascular and respiratory diseases. Day before and on the second day after surgery, patients performed 6MWT and subjectively rate the exertion according to Borg- RPE- Scale (before, immediately after and 10 minutes after the test). 6MWT distance, Borg scale ratings were analysed. On the second day after surgery 66% of patients from the SG and 58% from the CG did not complete the test. Patients from the SG before (500,07 ± 40,38 m) and on the second day after surgery (243,46 ± 18,18 m) achieved shorter distances compared to the CG (565,93 ± 20,41 m; 249,47 ± 26,66 m), p < 0,001 i p = 0,481. A statistically significant negative correlation between 6MWT distance before surgery and age of the patients was confirmed. Patients who did not develop complications achieved significantly longer distances on admission (p = 0,003 for SG, p = 0,004 for CG). For 6MWT before surgery and 2 days after surgery, patients from the SG showed a significantly higher level of fatigue compared to the CG after the test (before p = 0,001, after p = 0,001). Patients form the SG often discontinued 6MWT and less tolerated effort compared to the CG. Hence, 6MWT is useful tool for ascertaining physical capacity and ET.<b>Objective</b> The purpose of this study was to compare the outcome of the great saphenous vein (GSV) sparing versus stripping during Trendelenburg operation for varicose veins. <br><b>Methods</b> This was a prospective randomized study of primary varicose vein patients who underwent Trendelenburg operation. Data of patients operated on over a period of 16 months was collected, including below knee GSV diameter by Duplex Ultrasound and revised venous clinical severity score (rVCSS), calculated preoperatively and postoperatively at 2^nd, 4^th, and 8^th week. <br><b>Results</b> A total of 36 patients undergoing Trendelenburg operation were included in the study. Nineteen patients underwent GSV sparing while 17 underwent stripping of GSV till just below the knee after juxtafemoral flush ligation of the great saphenous vein. There was a significant decrease in the below-knee GSV diameter (19% after 2 months) and rVCSS (60.8%) in the sparing group. The stripping group also showed an almost similar decrease in below-knee GSV diameter (19.6% after 2 months) and rVCSS (66.3%). However, no significant difference was found between the two groups in terms of change in GSV diameter (P = 0.467) and rVCSS (P = 0.781). <br><b>Conclusion</b> Trendelenburg procedure with sparing of GSV can be done routinely for operative management of varicose veins, where surgery is needed.Haemostatic materials such as gelatine sponges, oxygenated cellulose meshes, tissue sealants, collagen matrices with human thrombin and fibrinogen are gaining on popularity in gastrointestinal surgery, especially in colorectal surgery. We searched for available scientific publications in the Pubmed and Cochrane database on the use of individual hemostatic materials in the field of gastrointestinal surgery. The analysis focused on the assessment of the safety of the use of individual materials in terms of the rate of bleeding complications and the rate of anastomotic leakage cases. The use of haemostatic materials has for years been a recognized method of reducing the rate of intra- and postoperative complications, both in gastrointestinal surgery and in other surgical specialties. Based on the available studies, it can be concluded that the use of hemostatic materials such as matrices, sponges and adhesives in gastrointestinal surgery, even in patients at high risk of anastomotic leakage and bleeding complications, reduces the incidence of complications.
