Aims Iliosacral sarcoma resections have been shown to have high rates of local recurrence (LR) and poor overall survival. There is also no universal classification for the resection of pelvic sarcomas invading the sacrum. This study proposes a novel classification system and analyzes the survival and risk of recurrence, when using this system. Methods This is a retrospective analysis of 151 patients (with median follow-up in survivors of 44 months (interquartile range 12 to 77)) who underwent hemipelvectomy with iliosacral resection at a single centre between 2007 and 2019. The proposed classification differentiates the extent of iliosacral resection and defines types S1 to S6 (S1 resection medial and parallel to the sacroiliac joint, S2 resection through the ipsilateral sacral lateral mass to the neuroforamina, S3 resection through the ipsilateral neuroforamina, S4 resection through ipsilateral the spinal canal, and S5 and S6 contralateral sacral resections). Descriptive statistics and the chi-squared test were used for categorical variables, and the Kaplan-Meier survival analysis were performed. Results Resections were S1 in 25/151 patients (17%), S2 in 70/151 (46%), S3 in 33/151 (22%), S4 in 77/151 (11%), S5 in 4/151 (3%), and S6 in 2/151 (1%). An internal hemipelvectomy was performed in 113/151 patients (75%), and 38/151 patients (25%) had an external hemipelvectomy. The predominant types of sarcoma were high-grade osteosarcoma in 48/151 patients (32%), chondrosarcoma in 41/151 (27%), Ewing sarcoma in 33/151 (22%), pleomorphic sarcoma in 17/151 (11%), and others in 2/151 (8%). LR was found in 24/151 patients (15%) with S3, S5, with S6 resections showing the highest rate of LR (p = 0.038). Overall, 19/151 patients (16%) had evidence of metastastic disease at the time of surgery and these patients showed poorer survival when compared to patients with no metastasis. Conclusion The proposed classification can help to report and compare different surgical and reconstructive approaches in these difficult cases who are still have a considerable risk of LR.

Background
The education sector experienced substantial impacts during the COVID-19 pandemic resulting from worldwide restrictions.

Purpose
To examine differences in the sleep patterns, sexual activity, screen use, and food intake of students and non-students during the COVID-19 pandemic.

Methods
This was a global cross-sectional study conducted in the second half of 2020 using multiple social media platforms to recruit study participants globally. A close-ended questionnaire was administered anonymously in English, French, Spanish, Portuguese, and Arabic to adults ages 18 and older. The outcome variables considered in analyses were changes in sleep pattern, sexual activity, screen use, and food intake. The explanatory variable was student status categorized as students vs. non-student. T-test, chi-square, and Mann Whitney U tests were used to assess differences between student and non-student populations. One logistic regression model was built for each outcome variable. Country of residence and country income level were included in the adjusted models.

Results
There were 17,008 participants of which 3,793 (22.3%) were students. Of the total sample, 4,889 (28.7%) reported changes in sleep, 4,642 (31.8%) reported increases in sexual activity, 10,278 (70.7%) reported increases in screen use, and 5,662 (40.2%) reported increases in food intake during the pandemic. Compared to non-students, students had significantly higher odds of reporting changes in sleep (AOR = 1.52), increases in sexual activity (AOR = 1.79), and increases in screen use (AOR = 1.36) but lower odds of reporting increase in food intake (AOR = 0.87).

Conclusion
Students displayed higher risk of experiencing changes in sleep, sexual behavior, and screen use during the COVID-19 pandemic. This has the potential to lead to broader adverse effects on students’ overall wellbeing. The findings and implications raise further obligations on the education sector to put extra-curricular support systems in place that address COVID-19 related behavior changes that have the potential to adversely impact students’ wellbeing.

Introduction
Diabetes mellitus (DM), hypertension and pulmonary tuberculosis (PTB) are catastrophic illnesses that collectively lead to increased mortality and premature death. However, the size of the problem and the appropriate approach to deal with the burden is still unclear. We aimed to evaluate the yield, number needed to screen (NNS) to prevent one death or adverse event for screening DM and hypertension and assess the prevalence and contributors to DM and/or hypertension.

Methods
Based on PTB contact tracing, a cross-sectional study was conducted among 801 PTB index cases and 972 household contacts from April 2019 to October 2020 in Guizhou, China. All the participants were screened for DM and hypertension. The yield was calculated as the proportion of newly detected cases among the study subjects, excluding known cases. The NNS was computed by dividing the number needed to treat for risk factors by the prevalence of the unrecognized diseases. The univariate and multivariate logistic regression analyses were applied to determine the independent predictors of DM and/or hypertension.

Results
Of the 1,773 participants, the prevalence of DM and hypertension was 8.7% (70/801) and 15.2% (122/801) in the PTB patients, 3.2% (31/972) and 14.0% (136/972) in the contacts, respectively. The prevalence of DM and/or hypertension was 21.2% (170/801) among the PTB patients and 15.4% (150/972) among their contacts. The screening yields to detect new cases of DM and hypertension among PTB patients were 1.9% and 5.2%, and that in the contacts were 0.8% and 4.8%, respectively. The NNS for DM was 359 for the PTB cases and 977 for the contacts, 299 for PTB cases and 325 for hypertension, respectively. Older age, under or overweight and obesity, family history hypertension and earlier diagnosis of other chronic conditions were the independent predictors for DM and/or hypertension among both PTB cases and their contacts.

Conclusion
Screening for DM and hypertension should be mandated in PTB patients and their household contacts to disclose undetected cases of these two conditions during TB contact tracing, which might reduce the potential cardiovascular disease deaths.

Resumo: Este trabalho pretende apresentar compreensões e experiências com o corpo na cosmopercepção yorùbá que possam redirecionar e guiar o desenvolvimento de uma psicologia corporal direcionada à população negra na diáspora brasileira. Para isso, proporcionou-se um caminhar pela noção de ser humano, a partir de tradições yorùbá, que nos aproximou da ideia de cosmopercepção, unidade, extencionismo e multifuncionalidade, trazendo o corpo como via de acesso às emoções, memórias, espiritualidade, ancestralidade e energia. Esses caminhos, nos fizeram perceber a importância da respiração, oralidade, ritmo e da conexão com partes do nosso corpo, fundamentais dentro da concepção yorùbá de ser humano, ampliando e trazendo novos modos de pensar conceitos fundamentais dentro da perspectiva da Análise Bioenergética, como corpo, espiritualidade e energia. Permitindo, assim, conduzir uma prática psicológica direcionado à população negra, que esteja enraizada em conhecimentos africanos e possam conduzir uma experiência de libertação e potência de vida.Palavras-Chave: Corpo; povo yorùbá; psicologia corporal; afrocentricidade. Abstract: This work intends to present understandings and experiences with the body in the Yorùbá cosmoperception that can redirect and guide the development of a body psychology aimed at the black population in the Brazilian diaspora. For this, a walk through the notion of human being was provided, from Yorùbá traditions, which brought us closer to the idea of cosmoperception, unity, extensionism and multifunctionality, bringing the body as a way of access to emotions, memories, spirituality, ancestry and energy. These paths made us realize the importance of breathing, orality, rhythm and connection with parts of our body, which are fundamental within the Yorùbá conception of the human being, expanding and bringing new ways of thinking fundamental concepts within the perspective of Bioenergetic Analysis, as the body , spirituality and energy. Thus, allowing the conduct of a psychological practice aimed at the black population, which is rooted in African knowledge and can lead to an experience of liberation and potential for life. keywords: Body; Yorùbá people; body psychology; afrocentricity.

Open surgical aortic valve replacement (SAVR) is a viable alternative to transcatheter implantation in low-risk patients. In this light, we evaluated the safety and effectiveness of SAVR performed through conventional and less invasive surgical approaches in a high-volume center.
We retrospectively reviewed the records of 395 consecutive patients who underwent open SAVR from January 2019 through December 2019 in our center. We evaluated and compared the operative results and postoperative major adverse outcomes of 3 surgical approaches: full median sternotomy (n=267), upper ministernotomy (ministernotomy) (n=106), and right anterior thoracotomy (minithoracotomy) (n=22).
Overall, the 30-day all-cause mortality rate was 0.8% (3 patients). Stroke occurred in 8 patients (2%), disabling stroke in 4 patients (1%), myocardial infarction in 1 (0.2%), and surgical site infection in 13 (3.2%). There was no difference in 30-day mortality rate or incidence of postoperative major adverse events among the 3 surgical groups. Stroke and surgical site infection occurred more frequently, but not significantly so, in the full-sternotomy group. The mean hospital stay was longer after full sternotomy (9.1 ± 5.5 d) than after ministernotomy (7.5 ± 2.9 d) or minithoracotomy (7.4 ± 1.9 d) (P=0.012).
Our findings suggest that open SAVR performed in a high-volume center is associated with a low early mortality rate and that less invasive approaches result in faster postoperative recovery and shorter hospital stays.

PLTU Tarahan Lampung Selatan menggunakan air laut sebagai air pendingin dalam kegiatan operasionalnya. Kegiatan tersebut menghasilkan limbah air panas yang berhubungan langsung dengan perairan, sehingga dapat mengakibatkan berubahnya suhu permukaan laut di perairan sekitarnya. Penelitian ini bertujuan untuk mengetahui sebaran horizontal limbah air panas di perairan laut sekitar outfall PLTU Tarahan Lampung Selatan. Data yang digunakan dalam penelitian ini meliputi Citra Landsat 8 TIRS, suhu permukaan laut lapangan dan arus permukaan laut lapangan, peta bathimetri yang diterbitkan oleh Pushidrosal, pasang surut yang diterbitkan oleh BIG yang diunduh pada laman http://ina-sealevelmonitoring.big.go.id dan peta RBI yang diterbitkan oleh BIG. Pengambilan data lapangan sebanyak 15 titik untuk mengetahui akurasi data citra dengan pengukuran lapangan. Hasil penelitian menunjukkan bahwa adanya kenaikan suhu permukaan laut oleh limbah air panas PLTU Tarahan Lampung Selatan sebesar 4oC dari suhu rata-rata laut di daerah outfall. Pola persebaran suhu permukaan laut membentuk setengah busur dengan luasan sebesar 39 hektar. Suhu tertinggi sebesar 33,5oC yang berada di dekat outfall dan terendah sebesar 29,4oC dan bergerak menuju arah tenggara dari outfall. The Steam Electricity Power Plant Tarahan South Lampung uses sea water for cooling water in its operational activities. The activity produces hot water waste that is directly related to the waters, so that it can lead to increased sea surface temperatures in the waters. Data used in this study include Landsat 8 TIRS imagery, field sea surface temperature and field sea surface currents, bathymetry maps published by Pushidrosal, tides data published by BIG which downloaded on the page http://ina- sealevelmonitoring.big.go.id and maps of the RBI from BIG. Field data capture as much as 15 points to know the accuracy of image data with measurement field. The results obtained from the research showed a rise in sea surface temperature of 4oC than the average temperature of the sea around the outfall. The distribution pattern of sea surface temperature forms a half arc with an area of 39 hectares. The highest temperature was 33.5oC which is near the outfall and the lowest was 29.4oC which is at the farthest point. The pattern of sea surface temperature difstribution was moving towards the Southeast from the outfall.

Published: January 2022

Abstract
The aim of this study was to explore the effects of dabigatran and rivaroxaban on the activities of various coagulation factors. To achieve that, 60 rabbits were randomly divided into experimental groups that received different doses of dabigatran or rivaroxaban. The effects of dabigatran and rivaroxaban on the activities of FII, FV, FVIII, FX, and activated protein C (APC) were analyzed. In the dabigatran groups, activated partial thromboplastin time and thromboplastin time (TT) were prolonged after drug administration, and the activities of FII, FV, FVIII, and FX were inhibited as the drug concentration increased. Low doses of dabigatran inhibited APC activity. In the rivaroxaban groups, APTT and TT were not significantly prolonged after drug administration. In contrast, the high-dose rivaroxaban group exhibited prolonged PT, and the degree of inhibition of the activities of FII, FV, FVIII, and FX increased as the drug concentration increased. Rivaroxaban had no significant effect on APC activity regardless of dosage. As the drug concentration increased, both NOACs had more significant inhibitory effects on the activities of FII, FV, FVIII, and FX. Low concentrations of dabigatran generated an inhibitory effect on APC activity, while high concentrations of dabigatran had no significant effect. Rivaroxaban had no significant effect on APC activity.

Abstract
While wood substances that contain water have shown a dielectric effect, they have never been directly proposed as a microwave absorption material to reduce artificial electromagnetic pollution. In this study, the microwave absorption efficiency of wood that contains water was investigated based on its dielectric properties in the microwave frequency range to optimize the parameters of wood unit cells, including the orientation, moisture content (MC) and thickness. Subsequently, inspired by the design concept of electromagnetic metamaterials, single-layer wood unit cells containing moisture were directly integrated into double epoxy resin layers. This procedure formed a natural wood-based metamaterial (NWM) with a simple periodic Sandwich structure without the need for further chemical modification and/or high energy consuming processes. Such design strategies allowed the NWMs to overcome the limitation of inherent dielectric properties of natural wood and present significantly enhanced microwave absorption performance, as well as different absorption behavior. NWMs at a MC ≤ 70% displayed a selective absorption mode, while NWMs at MC ≥ 85% showed a broadband absorption mode. Both absorption modes could achieve the peak absorptivity > 98%. Particularly, the NWM in the broadband absorption mode possessed an effective absorption (absorptivity > 90%) bandwidth of 9.04 GHz, which was 7.6 times that of natural wood (1.19 GHz). The NWMs performed well when irradiated by microwaves with different angles and directions. Also, the thickness of NWMs was only 7 mm, allowing easy incorporation of the materials in engineering designs. The use of sustainable materials, impressive performance, high stability, practical thickness, and the facile and cost-effective production technique demonstrated NWMs with great potential in designing green buildings.

Abstract
Hepatocellular carcinoma (HCC) is one of the most common human cancers. Long non-coding RNA (lncRNA) has been demonstrated to play an important role in regulating tumor development. The current study aims to explore the specific role of LINC00520 during HCC progression. The present study identified that LINC00520 was upregulated in HCC tissues and indicated poor patient survival. Overexpression of LINC00520 promoted HCC cell proliferation, migration and invasion, while LINC00520 downregulation led to the opposite effects. Besides, LINC00520 knockdown was found to inhibit tumor growth in vivo. Furthermore, LINC00520 acted as a sponge of miR-4516 to regulate SRY-related high mobility group box 5 (SOX5). In addition, the inhibition of miR-4516 partly reversed the inhibitory effect of LINC00520 silencing on HCC cell proliferation, migration and invasion. In conclusion, the inhibition of LINC00520 suppressed HCC cell proliferation, migration and invasion through mediating miR-4516/SOX5 axis. Therefore, our study provides a basis for the development of treatment strategies for HCC.
