title: VERTEBROPLASTY IN BONE FRAGILITY FRACTURES AND TUMOR FRACTURES: RISKS AND BENEFITS

description: ABSTRACT Objective: To evaluate the results of percutaneous vertebroplasty (PV) in spinal fragility fractures (osteoporosis/tumor), analyzing possible complications. Method: We evaluated 33 patients with spinal fractures (FXV) due to osteoporosis or tumor who underwent PV between January and November 2021. A physical examination was performed, obtaining the history and risk factors for bone fragility/tumor and a radiological evaluation of the spine to verify FXV. Genant’s semiquantitative method was used for postoperative classification, the VAS score, and a disability questionnaire (ODI). A radiologist evaluated tomographic control to quantify vertebral filling and extravasation, determining where they occurred. Results: 46 vertebrae of 33 patients were operated on, with a mean age of 71 years, and 11 patients with more than one level of surgery. Of the total, 13 patients had tumor fractures, and 20 had fractures due to insufficiency. PMMA extravasation was observed in 31 vertebrae, most frequently in the External Vertebral Venous Plexus (23), Discal Body (9), Anterior Epidural Recess (4), Pulmonary Vessels (4), Internal Vertebral Venous Plexus (3), Inferior Cava (2), Adipose Plane (2) and Azygos Vein (1). No patient had clinical complications. Furthermore, the mean preoperative VAS was eight, the postoperative one was 3, the mean preoperative ODI was 56, and the postoperative one was 30. Conclusion: PMMA extravasation was frequent in several locations and levels without any clinical complications. VP proved to be effective in improving pain and function. Level III; Longitudinal Retrospective Cohort Study.

title: Enzymatic hydrolysis of lignocellulosic residues and bromatological characterization for animal feed

description: ABSTRACT: This study evaluated the action of commercial and non-commercial cellulases and pectinases in the hydrolysis of soybean hulls (SH) and corn stover and cobs (CSC), the effect of temperature and agitation on the lignocellulosic substrate hydrolysis and the bromatological characteristics of hydrolyzed substrates. The effect of pretreatment on the hydrolysis of lignocellulosic residues and bromatological analysis were also evaluated. The highest hydrolytic activity occurred at 300 rpm for SH (47.95 and 51.43% for cellulase and pectinase, respectively) and at 350 rpm for CSC (26.05 and 9.23% for cellulase and pectinase, respectively). Non-commercial enzymes achieved 7.26-30% of the amount of hydrolysis obtained with commercial enzymes, on the same substrates. Pretreatment with 7.5% of NaOH and a particle size of the substrate of 0.5 mm significantly increased the hydrolysis of SH and CSC for both enzymes. The bromatological characteristics showed that soybean hulls hydrolyzed with both commercial cellulase and pectinase have potential for large-scale use in animal feed production.

title: Influence of stress triaxiality on the fracture behaviour of Ti6Al4V alloy manufactured by electron beam melting

description: Abstract This paper aims to investigate the influence of stress triaxiality on the fracture behaviour of Ti6Al4V fabricated by Electron Beam Melting (EBM). Here, specimens with seven configurations were manufactured and tested to obtain a wide range of stress triaxialities. A combined approach using Digital Image Correlation (DIC) and finite element (FE) modelling was used to evaluate the current stress triaxiality levels of the various specimens. The material fracture envelope was defined with the triaxiality in a range from -0.28 to 0.71, noting that the fracture was strongly dependent on the stress triaxiality. The characterisations were then carried out by testing an ad-hoc specimen to evaluate failure criteria at low and high stress triaxialities. It was shown that the FE model using the failure criterion based on triaxiality offers more accurate predictions of the material's failure response than that based on the effective plastic strain. The modelling approach based on anisotropic elasto-plasticity contributes to better predictions of the alloy's response. Thus, the failure models based on the stress triaxiality are highly recommended for producing accurate numerical predictions of the fracture response of Ti6Al4V-EBM.

title: Chromatographic Profiles of Ethyl Acetate Extracts Produced by Bacillus sp. Collected from the Mangroves in the Brazilian Northeast

description: The genus Bacillus is Gram-positive, anaerobic or aerobic facultative bacteria, often described to be associated with the mangrove rhizosphere. Secondary products of their metabolism, coming from places affected by pollution and environmental stresses, such as mangroves, have been attracting interest from the biotechnological point of view. In view of this scenario, this work analyzed the ethyl acetate extracts of the cultured Bacillus species, previously isolated from mangroves located in the state of Sergipe, Brazil. Chromatographic profiles of seven bacterial isolates collected from two different mangroves were analyzed using gas chromatography/mass spectrometry (GC-MS) and many important compounds of biotechnological interests, mainly those derived from azo-aromatic compounds such as pyrazines, pyrrolo-pyrazines, and piperazinediones, were detected. This study is one of the first, in our knowledge, prospecting volatile or semi volatile organic compounds from ethyl acetate extracts produced by bacteria isolated from the mangroves, and intents to increase the interest in this coastal ecosystem as a source of compounds with biotechnological applications.

title: Experience of a resident physician in general surgery basic area on board of an expedition in the amazon river

description: ABSTRACT Located in areas of difficult access, the riverside population of the upper Amazon River has a great demand for health care, whether in the scope of basic health promotion or in general or specialized medical care, surgical procedures, dental and pharmaceutical care. Taking this to consideration, the Barco Hospital Papa Francisco project was conceived and implemented, which aims to provide health care to riverside communities through expeditions that safely transfer health resources to populations located on the banks of the river. Having participated in one of the expeditions, it was possible to carry out a survey of data regarding the attendance and writing of a personal report on the impact on the professional activity. The expedition allowed the performance of a large number of surgical procedures in a condensed period, covering a wide variety of technical approaches essential to the performance of the general surgeon, among them, we can mention inguinal and incisional hernioplasties, umbilical and inguinal herniorrhaphy, postectomy and tubal ligation, lipoma excision, sebaceous cyst excision, nevi excision, among others (data available in the vessels Wareline® system).

title: Impact of proper surgical treatment on the survival of patients with epithelial ovary cancer

description: ABSTRACT Objective: to evaluate the quality of surgical treatment of ovarian cancer patients and assess the impact of adequate surgical oncological treatment on disease-free survival and overall survival of patients with advanced epithelial ovarian cancer. Methods: this is an observational, retrospective study with quantitative analysis, with the collection of data in medical records of a temporal convenience sample of patients diagnosed with ovarian cancer admitted to a High Complexity Oncology Unit, in Belo Horizonte, from the period of 2014 to 2020. Results: a total of 91 patients diagnosed with ovarian cancer were evaluated, with the epithelial histopathological type being the most frequent (85%). Of this total, 68 patients (74.7%) had advanced-stage ovarian cancer. Appropriate surgical treatment was performed in 30.9% of patients with advanced epithelial ovarian cancer and the type of performed surgery was statistically significant for overall survival. This low proportion of appropriate surgical oncological treatment was not related to surgical specially or surgeon competence, but mainly to advanced disease related to patient flow at UNACON. It was not possible to confirm if the advanced-stage disease was related to tumor biology or losing time from diagnosis to oncological surgery. Conclusion: overall survival of advanced-stage epithelial ovarian cancer patients is directly influenced by appropriate surgical treatment, however, in this study, the percentage of advanced ovarian cancer receiving adequate surgical treatment was much lower than the rates reported in the literature. To improve these outcomes, we believe that surgeons should keep following patients during neoadjuvant chemotherapy to point to a better time for surgery, and clinical oncologists should better consider adequate oncological surgery as one of the pillars of ovarian cancer treatment and get more involved in facilitating surgeries.

title: Perception of hippotherapy professionals about their practice with the elderly

description: Abstract Introduction Riding therapy is a therapeutic method recently regulated in Brazil. Nevertheless, it has been studied for years, especially focusing on children and adolescents. Considering the growing number of elderly in the Brazilian population, investigations focusing on older people are increasingly necessary. Objective To analyze the perceptions of equine therapy professionals about their practice with the elderly. Methods This was a qualitative and cross-sectional research, in which the participants answered an online questionnaire, composed of demographic questions and questions related to horseback riding with the elderly. Data were analyzed using descriptive statistics and thematic content analysis. Results Twenty-five professionals (23-57 years old), graduates, who had worked for at least two years with hippotherapy (mean = 6.64; standard deviation = 5.39 years) participated. This sample was composed mostly of female professionals (72%) and physical therapists (48%). Of the total, 60% reported having already assisted at least one elderly practitioner. Among those who had never worked with this public, 90% wished to do so. All professionals considered that horseback riding can be beneficial in old age, reducing depressive symptoms and promoting psychosocial (e.g., socializing) and physical (e.g., balance) variables. Despite the benefits, professionals mentioned challenges, such as difficulties of the practitioner (e.g., fear), problems with the workplace (e.g., lack of qualified staff), and low demand. Conclusion Hippotherapy professionals consider riding therapy a method that contributes to improving biopsychosocial aspects of the elderly. However, they face challenges in this practice, hindering or preventing them from serving older people.
