Avaliação da amplitude de movimento e força da cintura escapular em pacientes de pós-operatório tardio de mastectomia radical modificada
Breast cancer is the most frequent neoplasm among women; it is traditionally treated by surgery ranging from quadrantectomy to widened modified radical mastectomy, of which common sequels are changes in articular range of motion, muscle strength decrease, lymphedema, and adherences. The aim of this work is to evaluate shoulder motion range and muscle strength in late post-operative patients having undergone radical modified mastectomy. Nine women, mean aged 53.22±6,5 years, in 2-to-7 year post-operative span, were evaluated as to shoulder motion range and muscle strength of the surgery side, considering the contralateral shoulder and limb as the standard reference for comparison. Data were statistically analysed and significance level set at p=0.05. Results showed significant reduction in shoulder range of motion in all patients, mainly in active and passive flexion and abduction, as well as lesser muscle strength, especially in Middle Trapezius and Supraspinatus muscles, as compared to the healthy limb. Findings stress the need to physical therapy to be onset at immediate post-operative, in order to minimize possible sequels and improve women's quality of life.O câncer de mama é a neoplasia que mais afeta as mulheres e a cirurgia tem sido o tratamento de escolha, que pode assumir vários graus, até mastectomia radical modificada e alargada. Após a cirurgia, podem surgir seqüelas como alterações na amplitude articular do ombro homolateral, diminuição da força muscular, linfedema e aderências. O objetivo deste estudo foi avaliar a amplitude de movimento e força muscular da cintura escapular em mulheres submetidas à mastectomia radical modificada em pós-operatório tardio. Foram avaliadas nove mulheres, em pós-operatório de 2 a 7 anos, com média de idade de 53,22±6,5 anos. A amplitude de movimento e força muscular do lado da cirurgia foram avaliadas em relação ao membro contralateral, tomado como parâmetro normal. Os dados foram tratados estatisticamente e o nível de signifcância fixado em
OSTEOCHONDRAL AUTOLOGOUS TRANSPLANTATION FOR TREATING CHONDRAL LESIONS IN THE PATELLA
ABSTRACTObjective: The primary aim of this study was to assess the clinical and functional evolution of patients with total-thickness symptomatic cartilaginous injury of the patellar joint surface, treated by means of osteochondral autologous transplantation. Methods: This prospective study was conducted from June 2008 to March 2011 and involved 17 patients. The specific questionnaires of Lysholm, Kujala and Fulkerson were completed preoperatively and one year postoperatively in order to assess the affected knee, and SF-36 was used to assess these patients’ general quality of life. The nonparametric paired Wilcoxon test was used for statistical analysis on the pre and postoperative questionnaires. The data were analyzed using the SPSS for Windows software, version 16.0, and a significance level of 5% was used. Results: The Lysholm preoperative and postoperative average scores were 54.59 and 75.76 points (p < 0.05). The Fulkerson pre and postoperative average scores were 52.53 and 78.41 points (p < 0.05). Conclusions: We believe that autologous osteochondral transplantation is a good treatment method for total-thickness symptomatic chondral lesions of the joint surface of the patella

Chronic Traumatic Encephalopathy Presenting as Alzheimer's Disease in a Retired Soccer Player.
The relationship between soccer and chronic traumatic encephalopathy (CTE) is not well established. We report clinicopathological correlations in an 83-year-old retired center-back soccer player, with no history of concussion, manifesting typical Alzheimer-type dementia. Examination revealed mixed pathology including widespread CTE, moderate Alzheimer's disease, hippocampal sclerosis, and TDP-43 proteinopathy. This case adds to a few CTE cases described in soccer players. Furthermore, it corroborates that CTE may present clinically as typical Alzheimer-type dementia. Further studies investigating the extent to which soccer is a risk for CTE are needed

Exogenous OCT4 and SOX2 Contribution to In Vitro Reprogramming in Cattle
Mechanisms of cell reprogramming by pluripotency-related transcription factors or nuclear transfer seem to be mediated by similar pathways, and the study of the contribution of OCT4 and SOX2 in both processes may help elucidate the mechanisms responsible for pluripotency. Bovine fibroblasts expressing exogenous OCT4 or SOX2, or both, were analyzed regarding the expression of pluripotency factors and imprinted genes H19 and IGF2R, and used for in vitro reprogramming. The expression of the H19 gene was increased in the control sorted group, and putative iPSC-like cells were obtained when cells were not submitted to cell sorting. When sorted cells expressing OCT4, SOX2, or none (control) were used as donor cells for somatic cell nuclear transfer, fusion rates were 60.0% vs. 64.95% and 70.53% vs. 67.24% for SOX2 vs. control and OCT4 vs. control groups, respectively; cleavage rates were 66.66% vs. 81.68% and 86.47% vs. 85.18%, respectively; blastocyst rates were 33.05% vs. 44.15% and 52.06% vs. 44.78%, respectively. These results show that the production of embryos by NT resulted in similar rates of in vitro developmental competence compared to control cells regardless of different profiles of pluripotency-related gene expression presented by donor cells; however, induced reprogramming was compromised after cell sorting

Effects of hospital facilities on patient outcomes after cancer surgery: an international, prospective, observational study
© 2022 The Author(s). Published by Elsevier Ltd. This is an Open Access article under the CC BY 4.0 licenseBackground: Early death after cancer surgery is higher in low-income and middle-income countries (LMICs) compared with in high-income countries, yet the impact of facility characteristics on early postoperative outcomes is unknown. The aim of this study was to examine the association between hospital infrastructure, resource availability, and processes on early outcomes after cancer surgery worldwide. Methods: A multimethods analysis was performed as part of the GlobalSurg 3 study—a multicentre, international, prospective cohort study of patients who had surgery for breast, colorectal, or gastric cancer. The primary outcomes were 30-day mortality and 30-day major complication rates. Potentially beneficial hospital facilities were identified by variable selection to select those associated with 30-day mortality. Adjusted outcomes were determined using generalised estimating equations to account for patient characteristics and country-income group, with population stratification by hospital. Findings: Between April 1, 2018, and April 23, 2019, facility-level data were collected for 9685 patients across 238 hospitals in 66 countries (91 hospitals in 20 high-income countries; 57 hospitals in 19 upper-middle-income countries; and 90 hospitals in 27 low-income to lower-middle-income countries). The availability of five hospital facilities was inversely associated with mortality: ultrasound, CT scanner, critical care unit, opioid analgesia, and oncologist. After adjustment for case-mix and country income group, hospitals with three or fewer of these facilities (62 hospitals, 1294 patients) had higher mortality compared with those with four or five (adjusted odds ratio [OR] 3·85 [95% CI 2·58–5·75]; p<0·0001), with excess mortality predominantly explained by a limited capacity to rescue following the development of major complications (63·0% vs 82·7%; OR 0·35 [0·23–0·53]; p<0·0001). Across LMICs, improvements in hospital facilities would prevent one to three deaths for every 100 patients undergoing surgery for cancer. Interpretation: Hospitals with higher levels of infrastructure and resources have better outcomes after cancer surgery, independent of country income. Without urgent strengthening of hospital infrastructure and resources, the reductions in cancer-associated mortality associated with improved access will not be realised.
