title: Simulated training model in a low cost for laparoscopic inguinal hernioplasty

description: ABSTRACT Purpose Develop a 3D model for the simulation of laparoscopic inguinal hernioplasty transabdominal preperitoneal (TAPP). Methods This is an experimental study, 18 participants were selected, divided into three groups, experimental (GE) surgeons in training, control (GC) experienced surgeons and Shaw (GS) nonexperienced surgeons. The simulation in the 3D model was carried out in 6 sessions fulfilling the 5 stages. Opening the peritoneum with the creation of the preperitoneal space; identification of important structures; hernia identification and reduction; placement and fixation of the mesh in Cooper’s ligament and closure of the peritoneum. Results In the 1st stage, the GE obtained an average of 1.25 ± 0.42 in the 1st session and 3.25 ± 0.62 in the 6th session (p = 0.05) and in the 5th stage 0.91 ± 0.29 in the first session. 1st session and 1.91 ± 0.29 in the 6th session (p = 0.001), with no significant difference between groups. The learning and skill curve in the SG represented 1.08 ± 0.29 1st and 3.50 ± 0.90 6th session (p = 0.001). Conclusions The creation of a systematization of training in simulation applied to the three-dimensional model enabled gain in laparoscopic skills and underpinned its theoretical and practical foundations.

title: Weight loss and adherence to postoperative follow-up after vertical gastrectomy for obesity treatment

description: ABSTRACT Purpose To analyze the effectiveness of vertical gastrectomy in the treatment of obese patients, adherence to clinical follow-up and the influence of factors such as gender and age. Methods This is a retrospective, observational and descriptive study, conducted with patients undergoing vertical gastrectomy, operated at Hospital São Domingos, between January 2016 and July 2018. Results Most patients undergoing vertical gastrectomy were female (n = 193, 72.28%) and had a mean age of37.11 ± 8.96 years old. The loss of follow-up was 56.18%. Among adherent patients (n = 117; 43.82%), most patients were female (n = 89; 76.07%) and had a mean age of 37.92 ± 9.85 years old. The mean body mass index (BMI) of the adherents in the preoperative was 37.85 ± 3.72 kg/m2. Both BMI and excess weight (EW) showed a statistically significant difference between pre- and postoperative period. Percentage of excess weight loss (% EWL) was satisfactory for 96.6% of adherent patients. Older patients had a statistically significant lower % EWL compared to the other groups. Conclusions Vertical gastrectomy was effective in the treatment of obese patients, with significant weight loss.

title: Reduction in pregnancies and litters in mice couples with splenectomized male

description: ABSTRACT Purpose The spleen is relevant in blood purification, hematopoiesis, metabolism, and immune response to antigens, in addition to the storage and control on the release of metals and amino acids. Its functions concerning reproduction characteristics are still unknown. The objective was to study the influence of splenectomies on reproduction. Methods This study analyzed 25 mice couples, distributed into five groups: group 1 – control, no surgery: group 2 – control, submitted to laparotomy and laparorrhaphy only; group 3 – splenectomy in male mice; group 4 – splenectomy in female mice; group 5 – splenectomy in male and female mice. The animals were studied as regards the number of gestations and offspring generated in each gestation. Results A decrease in both the number of gestations and the number of offspring was verified in the male mice that had received a splenectomy when coupled with normal female mice. It is important to emphasize lower reproduction level when paired asplenic males with normal females, otherwise, the couples in which both mice had been splenectomized did not present change in the reproduction pattern. Conclusions A reduction in the number of pregnancies and litters occurs in mice couples when the male mice were previously splenectomized.

title: Percutaneous application of allogeneic adipose-derived mesenchymal stem cell in dogs submitted to minimally invasive plate osteosynthesis of the tibia

description: ABSTRACT Purpose To evaluate clinical outcome following minimally invasive plate osteosynthesis (MIPO) associated with percutaneous transplantation of allogeneic adipose-derived mesenchymal stem cells (AD-MSC) at the tibial fracture site in dogs. Methods Thirty-six dogs presenting with nonarticular complete tibial fracture were included in this study. All fractures were treated by the same MIPO technique. The animals were divided in group 1 (n = 20) received a percutaneous application of 3 × 106 AD-MSC at the fracture site and group 2 (n = 16) did not receive any adjuvant treatment. Postoperative radiographic examinations were made at 15, 30, 60, 90 and 120 days. Results Fifty-eight percent of the patients were classified as skeletally immature. The median weight of the animals was 18.8 kg. The mean radiographic union time differed statistically between the AD-MSC group (28.5 days) and the control group (70.3 days). Sixty percent of dogs in group 1 and 56.25% of the group 2 were considered immature. Conclusions The use of allogeneic AD-MSC cell therapy and MIPO is a safe, viable and effective technique for promoting bone healing in nonarticular tibial fractures in dogs.

title: Light-emitting diode stimulates radiodermatitis recovery

description: ABSTRACT Purpose To evaluate the effect of light-emitting diode (LED) in an experimental model of radiodermatitis. Methods Ten male Wistar rats weighing 200–250 g were analyzed. Radiation was delivered in a single dose (20 Gy with Strontium-90 dermatological plaques), two areas per animal. After 15 days, they were divided into two groups: control group (n = 5) and LED group (n = 5), which was treated during 21 days later (LED 660 nm, 10 min in alternate days). The endpoints were radiodermatitis scale, histological analysis HE, Picrius Sirius and the gene expression of interleukin-10 (IL-10) and matrix metalloproteinase-9 (MMP-9). Results The LED group showed a higher number of dermal appendages (p = 0.04) and angiogenesis(p = 0.007), a tendency towards higher IL-10 (p = 0.06) and an increase in MMP-9 (p = 0.004) when compared to the control group. Conclusions This study suggested that the use of LED for radiodermatitis increased skin regeneration.

title: A castor oil plant (Ricinus communis)-derived implant improves the biomechanical properties of noncritical bone defects

description: ABSTRACT Purpose The biomechanical properties of the polyurethanes implant material derived from castor oil plant (Ricinus communis) were evaluated in a noncritical bone defect model in rat tibia. Methods After three weeks of the implant application, the tibias were tested by means of the biomechanical three-point flexion test and resistance, rigidity, energy at maximum load and maximum energy were evaluated. Nonparametric statistical analysis was performed. Results It was found that the group that received the implant behaved the same as the intact control group and also showed a significant increase in maximum load compared to the spontaneous repair group. Conclusions Our results indicate that the tibias with the implant material in a noncritical bone defect recover normal biomechanical parameters in less time than spontaneously.

title: Techniques of orthotopic renal transplantation in pigs. One donor to two recipients via inverted grafting

description: ABSTRACT Purpose Although transplanting two kidneys from a single donor to two recipients has some advantages, the right and left kidneys are not anatomically identical; thus, a surgical procedure considering the anatomical features of the donor kidneys is needed when transplanting them into the opposite renal fossae. Based on vast experience, the surgical details of pig orthotopic kidney transplantation from one donor to two recipients was reported. Methods When the right kidney was transplanted to the left renal fossa, the graft was inverted upside down, not backwards, thus ensuring that the anteroposterior relationship of the renal vessels was maintained and anatomically natural vascular anastomosis could be performed. Results Using this technique, we could have developed a pig experimental model that is safe and has a high success rate, even for researchers in the middle of their training. This technique of inverting the graft upside down was reported in human kidney transplantation to make vascular anastomosis easier. Conclusions In pig orthotopic kidney transplantation from one donor to two recipients, an anatomically natural vascular anastomosis could be performed via inverted grafting when the right kidney was transplanted into the left renal fossa.

title: Cordycepin prevents the esophageal stricture formation in the alkali-burn rat model by exerting anti-inflammatory and antifibrotic effects

description: ABSTRACT Purpose To investigate the efficacy of cordycepin, an adenosine analogue, on prevention of esophageal damage and stricture formation due to esophageal caustic burns in rat model comparing with prednisolone. Methods Caustic esophageal burn was introduced by 37.5% of NaOH to distal esophagus. Thirty-two Wistar albino rats were divided in four groups: sham rats undergone laparotomy, treated with 0.9% NaCl; control rats injured with NaOH without cordycepin treatment; cordycepin group injured with NaOH, treated with 20 mg/kg cordycepin; prednisolone group injured with NaOH, treated with 1 mg/kg prednisolone for 28 days. Efficacy was assessed by histopathological and immunohistochemical analysis of esophageal tissues. Results Cordycepin treatment significantly decreased inflammation, granulation tissue and fibrous tissue formation and prevented formation of esophageal strictures shown by histopathological damage score and stenosis indexes compared to control group (p &lt; 0.01). These effects are relatively more substantial than prednisolone, probably based on attenuation of elevation of proinflammatory cytokines hypoxia-inducible factor 1-alpha (HIF-1?), tumor necrosis factor alpha (TNF-?), proliferative and fibrotic factor fibroblast growth factor 2 (FGF2) and angiogenic factor vascular endothelial growth factor A (VEGFA) (p &lt; 0.05). Conclusions The findings suggest that cordycepin has a complex multifactorial healing process in alkali-burned tissue, more successful than prednisolone in preventing the formation of esophageal strictures and may be used as a therapeutic agent in the acute phase of esophageal alkali-burn.

title: Food intake and nutritional status of preschool from maroon communities of the state Alagoas, Brazil

description: OBJECTIVE: To assess the dietary intake and the nutritional status of children from Alagoas maroon communities. METHODS: Cross-sectional study involving 724 children (12-60 months) from 39 Alagoas maroon communities. The nutritional status was investigated by anthropometric, biochemical (hemoglobin) and food consumption indicators. RESULTS: The prevalence of anemia, stunting and obesity were, respectively, 48.0, 9.7 and 6.0%. The children had a monotonous eating pattern and a considerable prevalence of inadequate intake of zinc (17.0%), folate (18.1%), iron (20.2%) and vitamins A (29.7%) and C (34.3%). Compared to the other socioeconomic classes, the E class children had lower average consumption (p&lt;0.05) for energy, carbohydrate, vitamins A and C, folate, iron, zinc and phosphorus. CONCLUSIONS: Anemia is a serious Public Health problem. The prevalence of chronic malnutrition and obesity were similar to those observed for the children in the State as a whole, where a nutritional transition process is occuring. There was a high prevalence of inadequate food intake risk for zinc, folate, iron and vitamins A and C, suggesting the need for nutritional education actions.
