A theoretical investigation is also conducted, revealing a very interesting analytic relation, i.e., that the choice of the weight constant and weight functions does not only influence the Fisher-consistent property (population minimizer of expected risk with a specific loss function leads to the Bayes optimal decision rule) but also interacts with privacy-preserving levels to affect the performance of classifiers significantly.In this article, to maximize the dimension of controllable subspace, we consider target controllability problem with maximum covered nodes set in multiplex networks. We call such an issue as maximum-cost target controllability problem. Likewise, minimum-cost target controllability problem is also introduced which is to find minimum covered node set and driver node set. To address these two issues, we first transform them into a minimum-cost maximum-flow problem based on graph theory. Then an algorithm named target minimum-cost maximum-flow (TMM) is proposed. It is shown that the proposed TMM ensures the target nodes in multiplex networks to be controlled with the minimum number of inputs as well as the maximum (minimum) number of covered nodes. Simulation results on Erdős-Rényi (ER-ER) networks, scale-free (SF-SF) networks, and real-life networks illustrate satisfactory performance of the TMM.Gastric carcinoma (GC) is an Epstein-Barr virus (EBV)-associated malignancy characterized by early metastasis. Unlike that of cellular micro(mi)RNAs, the role of viral miRNAs in epithelial-mesenchymal transition (EMT) and metastasis in cancers has not been fully investigated. In this study, we elucidated the involvement of miR-BART11, an EBV-encoded viral miRNA, in the EMT and metastasis of GC cells. EBV-miR-BART11 upregulation can lead to downregulation of forkhead box protein P1 (FOXP1) in both tissues and cell lines of gastric carcinoma. Downregulation of FOXP1 might trigger the secretion of interleukin 1β (IL-1β), IL-6, and 1L-10 in cancer cells, resulting in poor survival of GC patients. We found that the observed EMT phenotypes resulted from the EBV-miR-BART11 overexpression-induced FOXP1 downregulation, which impacted the expression of the EMT-transcription factors E-cadherin and snail. We further demonstrated that conditioned medium-derived tumor-associated macrophages (TAMs) promoted phenotypic changes and expression of EMT-related molecules in GC cells. Additionally, EMT changes were significantly promoted in GC cells cultured in conditioned medium from TAMs infected with EBV-miR-BART11-containing lentivirus. On the contrary, GC cells cultured in conditioned medium from TAMs infected with FOXP1-carrying lentivirus showed little or no EMT change. Taken together, our results suggest that EBV-encoded viral miRNA BART11 downregulates the FOXP1 transcription factor, and promotes EMT by directly influencing gastric tumor cells or indirectly affecting the tumor microenvironment, which might, in turn, accelerate cancer invasion and metastasis, thereby affecting the survival and prognosis of patients.Introduction During the recent months, COVID-19 has turned to a global crisis claiming high mortality and morbidity among populations. Despite the high prevalence of the disease, it has currently no definitive treatment. We here reported the effects of intravenous immunoglobulin (IVIG) administration in severely ill COVID-19 patients diagnosed based on PCR and radiology tests. Case presentation Five severely ill COVID-19 patients in whom standard treatments failed were administrated with IVIG which prevented the deterioration of clinical symptoms. All the patients were treated with high-dose IVIG (0.3-0.5 g/kg) for 5 consecutive days so that no patient would receive lower than 25 g of the drug. All the patients showed a desirable therapeutic response and were discharged from the hospital with a stable clinical condition after being recovered. Conclusion Treatment with IVIG at the therapeutic dose of 0.3-0.5 g/kg can improve the clinical condition and O2 saturation and prevent the progression of pulmonary lesions in COVID-19 patients with severe symptoms in whom standard treatments have failed.Purpose Providers have cited fear of taking away hope from patients as one of the principal reasons for deferring advance care planning (ACP). However, research is lacking on the relationship between ACP and hope. We sought to investigate the potential association between ACP and hope in advanced cancer. Methods This is a cross-sectional analysis of baseline data from a primary palliative care intervention trial. All patients had advanced solid cancers. Three domains of ACP were measured using validated questions to assess discussion with oncologists about end-of-life (EOL) planning, selection of a surrogate decision maker, and completion of an advance directive. Hope was measured using the Hearth Hope Index (HHI). Multivariable regression was performed, adjusting for variables associated with hope or ACP. Results A total of 672 patients were included in this analysis. The mean age was 69.3 ± 10.2 years; 54% were female, and 94% were White. Twenty percent of patients (132 of 661) reported having a discussion about EOL planning, 51% (342 of 668) reported completing an advance directive, and 85% (565 of 666) had chosen a surrogate. There was no difference in hope between patients who had and had not had an EOL discussion (adjusted mean difference in HHI, 0.55; P = .181 for adjusted regression), chosen a surrogate (adjusted HHI difference, 0.31; P = .512), or completed an advance directive (adjusted HHI difference, 0.11; P = .752). Conclusion In this study, hope was equivalent among patients who had or had not completed 3 important domains of ACP. These findings do not support concerns that ACP is associated with decreased hope for patients with advanced cancer.Purpose Management of soft tissue and bone sarcoma presents many challenges, both diagnostically and therapeutically, and requires multidisciplinary collaboration; however, such collaboration is often challenging to establish, especially in the community setting. We share our experiences of a virtual multidisciplinary sarcoma case conference (VMSCC). Methods We conducted retrospective review of the VMSCC data-initially via Webex, now Microsoft Teams-and the surveys of referring physicians to understand the feasibility and value of the VMSCC. Results The VMSCC was established in March 2013 in Kaiser Permanente Northern California with consistent participation of the Departments of Musculoskeletal Oncology (orthopedic oncology), Musculoskeletal Radiology, Pathology, Medical Oncology, Radiation Oncology, Nuclear Medicine, Surgical Oncology, and Genetics. Pediatric Oncology participated ad hoc when pediatric sarcoma cases were presented. Referrals were from multiple specialties and regions, including the Kaiser Permanente Mid-Atlantic and Hawaii regions. From March 2013 to December 2019, 1,585 cases were reviewed encompassing 36 histologic types. More than 300 cases were reviewed per year from 2017 to 2019. Survey results of referring physicians demonstrate that the VMSCC enhanced the confidence of treating physicians, and its recommendations frequently led to treatment changes. Conclusion Establishing a valuable community-based VMSCC is feasible. VMSCC recommendations frequently led to treatment changes and improved the confidence of treating physicians.Competency-based medical education is an educational innovation implemented in health professions worldwide as a means to ensure graduates meet patient and societal needs. The focus on student-centered education and programmatic outcomes offers a series of benefits to learners, institutions and society. However, efforts to establish a shared, comprehensive competency-based framework in veterinary education have lagged. This article reports on the development and outcome of a competency-based veterinary education (CBVE) framework created through multi-institutional collaboration with international input from veterinary educators and veterinary educational leaders. The CBVE Framework is designed to reflect the competencies expected of new graduates from member institutions of the Association of American Veterinary Medical Colleges (AAVMC). The CBVE Framework consists of nine domains of competence and 32 competencies, each supplemented with illustrative sub-competencies to guide veterinary schools in implementing competency-based education in their local context. The nine domains of competence are clinical reasoning and decision-making; individual animal care and management; animal population care and management; public health; communication; collaboration; professionalism and professional identity; financial and practice management; and scholarship. Developed through diverse input to facilitate broad adoption, the CBVE Framework provides the foundation for competency-based curricula and outcomes assessment in veterinary education internationally. We believe that other groups seeking to design a collective product for broad adoption might find useful the methods used to develop the CBVE Framework, including establishing expertise diversity within a small-to-medium size working group, soliciting progressive input and feedback from stakeholders, and engaging in consensus building and critical reflection throughout the development process.A 5-year World Organisation for Animal Health Veterinary Twinning Program between Massey University, New Zealand, and the University of Peradeniya, Sri Lanka, was initiated in 2014. The key aims of the project were renewal of the curriculum, rejuvenation of teaching methodology, and creation of a platform for sustainable clinical and extension livestock services within the teaching program The project succeeded in facilitating the development of a new veterinary undergraduate curriculum that was based upon student-centered and problem-based approaches to teaching and learning. Key reasons for the success of the project were (a) perceptions for the necessity of changes at the University of Peradeniya; (b) the management of expectations of both partners in the program along with their key stakeholders; (c) allowing sufficient time (i.e., 5 years) for agreement, establishment, and implementation of the changes; and (d) the development of the relationships of trust between faculty of the partner institutions at both decision-making and grassroots levels. From a project management perspective, the project required bringing about significant change in another organization, in a foreign country, and with a distinctly different culture. Moreover, notwithstanding the value of a long project, project managers should be prepared for significant political, organizational, and personnel change over the duration of such a project.This collaborative partnership aimed to enhance the quality of veterinary education at both Sokoine University of Agriculture (SUA), College of Veterinary Medicine and Biomedical Sciences (Tanzania), and Kansas State University (KSU), College of Veterinary Medicine (United States), by facilitating exchange of knowledge, experience, and ideas. One project objective was to integrate the World Organisation for Animal Health (OIE) Guidelines on Veterinary Education Core Curriculum into the SUA education program so veterinary graduates would be equipped with the minimum competencies needed to support their National Veterinary Services (OIE Day One Competencies). Curriculum mapping revealed that partners addressed different OIE Day One Competencies to varying degrees and they had complementary strengths and weaknesses. The partners' practical and educational experiences were also complementary, providing each opportunities to learn from the other and a solid basis for long-term mutually beneficial collaboration. Through structured exchanges, the collaboration allowed SUA and KSU students and faculty to broaden their perspectives by exposing them to veterinary medicine, culture, ecosystems, teaching environments, and farming systems in each other's country.
