New intragastric sleeve technique reduces adipose tissue in pig experimental model: tomographic study

Scientific Reports (2020)

Mariana da Silva Ribeiro Ricardo Paiva Araújo dos Scheiba Zorron Saulo José Quina Silva Silvia Marcela Ruiz Cadena Marcelo Borges dos Santos

Abstract In order to implement a new bariatric surgery technique, we verify the efficacy of intragastric sleeve to reduce weight gain and subcutaneous adipose tissue (SAT). Animals were divided into two groups: G1 (single-port intragastric sleeve) and G2 (sham group). The stomach was surgically reduced by single-port intragastric sutures to fo a gastric sleeve. Animals were submitted to computer tomography (CT) before the surgical procedure and after 18 weeks. Images were analyzed and measurements of the thickness of SAT, depth and width of the longissimus dorsi muscle and the rib eye area were made. Body weight and CT measurements were analyzed using the GLM PROC. The correlation coefficients were calculated among weight, moments and measures. There was a significant difference in weight gain, in which G1 had an average of 42.803 ± 3.206 kg, lower than G2 (45.966 ± 4.767 kg). The mean values for SAT and muscle measurements differed significantly between groups, in which G1 achieved the lowest values. All variables had significant correlations and high magnitude. Intragastric sleeve surgery induced a significant decrease of SAT. The new intragastric sleeve technique is feasible, safe and effective, mainly in reducing fat deposition, making it an important alternative in bariatric surgical treatment.

Interventionist videothermometry: a new model of cardiac ischemia evaluation

BMC Veterinary Research (2020)

Abstract Background The purpose of the present study was to evaluate, through videothermometry, the temperature variation in the hearts of rabbits, that underwent induced myocardial ischemia and reperfusion. Results A total of 20 female rabbits were divided into two groups: a treated group and a sham group, the treatment group underwent 5 min of cardiac arrest and reperfusion, using the inflow occlusion technique. Throughout the experiment, the animals were monitored by videothermometry, observing the thermal variations of the myocardial tissue. During the experiment, at different times, blood gas tests and tests to evaluate the lactate concentrations were performed. At the end of the experiment, each heart was submitted to histopathological evaluation. In the treated group, there was a reduction in temperature of the myocardial tissue during the circulatory arrest compared to the sham group. Additionally, a colder area next to the caudal vena cava ostium and the right atrium was observed. Notably, despite the 5 min of cardiac arrest in the treated group, both the lactate and bicarbonate levels were maintained without significant variation. However, there was an increase in PaCO2 and pH reduction, featuring respiratory acidosis. In relation to the histopathological study, the presence of hydropic degeneration in the myocardium of animals in the treated group was observed. Conclusions Based on these results, the videothermometry was efficient in identifying the range of myocardial tissue temperature, suggesting that the first areas to suffer due to cardiac arrest were the caudal vena cava ostium and the right atrium. However, in regard to the angiographic coronary thermography, the study was not feasible due to the small size of the coronary. There was no variation between the groups regarding the presence of myocardial infarction, myocardial congestion, myocardial edema and myocardial hemorrhage.

Remote metastasis detection by video thermometry: A promissing preclinical study

Abstract The thermometric video image (VTM) can guide the search for distant metastases, once the vascular architecture is known, identifying, by segmentation, the tumor thermal impression and a similar pattern at a distance. Thus, suspicious areas can be better investigated, improving the postoperative prognosis. In this study, it was possible to observe the assertive capacity of video thermometry in identifying distant metastases and breast tumors in female dogs, not palpable or visible to the naked eye, in relation to conventionally used techniques. It was also possible to identify textures with anatomical limits, from emboli to early formations of carcinomas, adenocarcinomas and adenomyoepithelioma. It was also possible to find non-neoplastic changes such as dermatitis, lipoma, hyperplasia and breast cysts. it can be concluded that the video thermometry (VTM) technique was capable of identifying distant metastases from the primary tumor and other benign alterations with great precision. However, for this to be possible, it is essential that the processing be carried out by SaMD (Software as a Medical Device), with tools capable of identifying patterns and thermal signatures, just like the algorithm, thus increasing the efficacy of the technique.
