29-238.Coronavirus disease 2019 (COVID-19) resulted in a global pandemic and has overwhelmed health care systems worldwide. In this scientific statement, we describe the epidemiology, pathophysiology, clinical presentations, treatment, and outcomes of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and multisystem inflammatory syndrome in children and young adults with a focus on cardiovascular manifestations and complications. We review current knowledge about the health consequences of this illness in children and young adults with congenital and acquired heart disease, the public health burden and health disparities of this infection in these populations, and vaccine-associated myocarditis.The alleviation of neoadjuvant immunochemotherapy (NICT) and neoadjuvant chemoradiotherapy (NCRT) was compared for esophageal squamous cell carcinoma (ESCC), and the correlation between the expression and changes of PD-L1 and the efficacy of NICT was evaluated in this study. Fourteen patients with ESCC who received preoperative NICT were included in group A, and fourteen patients with ESCC who received preoperative NCRT were included in group B. Next, group A was divided into CR (complete response), PR (partial response), and NR (no response) according to the degree of pathological response. Also, the expression and changes of PD-L1 (CPS, TPS, IPS) before and after treatment were compared between the groups. We observed that after the treatment, the expression of PD-L1 in both groups was higher than before treatment. In group B, the expression of PD-L1 was elevated in 92.8% of patients, which was higher than that in group A, which had significantly increased IPS (p less then 0.05). In group A, 9 (64.2%) patieill achieve a good response by NICT. As NCRT can upregulate the expression of PD-L1, the low preoperative expression of PD-L1 is no contraindication for immunotherapy, which provides a new basis and prognostic indexes for chemoradiotherapy combined with immunotherapy.Enhancer of Zeste Homologue 2 (EZH2) as a histone methyltransferase epigenetically regulates laryngeal carcinoma (LGC) progression. The present study sought to explore the role and mechanism of EZH2 in the epithelial-mesenchymal transition (EMT) of LGC cells. Expressions of EZH2, secreted frizzled-related protein 1 (SFRP1), and trimethylation of lysine 27 on histone H3 (H3K27me3) in LGC tissues or cells were detected via reverse transcription quantitative polymerase chain reaction (qRT-PCR) and western blotting. Upon transfection of si-EZH2, si-SFRP1, oe-SFRP1, or H3K27me3 upregulation, cell viability was assessed via cell counting kit-8, protein levels of E-cadherin, N-cadherin, β-catenin, c-Myc, and Cyclin D1 were determined via western blotting, and Vimentin expression was determined via immunofluorescence. The enrichment level of H3K27me3 in the SFRP1 promoter was measured via chromatin immunoprecipitation-PCR. EZH2 was highly expressed in LGC tissues and cells. Silencing EZH2 repelled the EMT of LGC cells. Mechanically, EZH2 upregulated H3K27me3 in the SFRP1 promotor to inhibit SFRP1 expression, and SFRP1 overexpression inactivated the Wnt pathway. H3K27me3 upregulation or SFRP1 downregulation reversed the inhibition of silencing EZH2 in the EMT of LGC cells. Overall, EZH2 upregulated H3K27me3 in the SFRP1 promoter to inhibit SFRP1 expression and activate the Wnt pathway, thereby facilitating the EMT of LGC cells.Secreted protein acidic and rich in cysteine (SPARC) plays a crucial role in the formation and progression of tumors. DNA methylation has become increasingly recognized as a frequent event of epigenetic alterations and one of the primary mechanisms of gene inactivation. The study aims to investigate the status of DNA methylation and the biofunction of SPARC in breast cancer. The qRT-PCR, BGS, and MSP methods were respectively employed to measure the relative mRNA expression levels and methylation status of SPARC. CFSE Additionally, the effects of SPARC on cell proliferation, migration, and invasion were examined in SPARC overexpression and knockdown cells. Immunohistochemical staining and western blot assay were used to examine the protein expression of genes. The expression levels of SPARC were found to be higher in breast cancer tissues and most breast cancer cells. The expression levels of SPARC in MDA-MB-231 and MCF-7 cells were significantly reversed by 5-Aza-dC treatment. Furthermore, the high expression and promoter DNA hypomethylation of SPARC were detected in triple-negative breast cancer tissues, while no expression changes of SPARC were found in luminal A breast cancer tissues. Overexpression of SPARC dramatically promoted MCF-7 cells migration and invasion, while knockdown of SPARC inhibited MDA-MB-231 cells migration and invasion. SPARC was involved in the epithelial-mesenchymal transition (EMT) process of breast cancer cells. The expression levels of mesenchymal markers N-cadherin, Vimentin, and β-catenin were upregulated, while E-cadherin was downregulated in SPARC overexpressed breast cancer cells. Conversely, the expression levels of EMT-related genes demonstrated the opposite trend in SPARC knockdown cells. To conclude, high expression of SPARC regulated by promoter hypomethylation promotes breast cancer cells migration and invasion, thus SPARC may act as an oncogene and serve as a potential target for breast cancer therapy.
In this review article, we discuss the role of chemotherapy, surgery, and radiation therapy in the treatment of brain metastases from germ cell tumors (GCT).

GCT rarely metastasize to the brain and there is limited data to guide management. Most instances of brain metastases occur in patients with non-seminomatous germ cell tumors (NSGCT).

We searched PubMed using the terms 'central nervous system (CNS) metastases' or 'brain metastases' and 'germ cell' from 2011 through August 2021. Review articles and prospective trials related to the treatment of brain metastases in GCT were included in addition to articles obtained by hand search of the references and clinical practice guidelines.

We highlight the importance of using chemotherapy as first-line therapy in most situations. We discuss the very minimal data regarding surgery and its primary role when there is significant mass effect or brain shift. We also compare whole brain radiation therapy (WBRT) with the use of radiosurgery. We then provide overall recommendations based on the reviewed data and our experience as a referral center for GCT.

This review will focus on the late neurological complications from cranial irradiation and relevant mitigation strategies.

Radiotherapy (RT) remains an important pillar in the management of brain metastases. Patients being treated in the modern era do experience longer survival, because of superior intra- and extra-cranial disease control. As a result, they can be more prone to developing and manifesting late complications post-brain radiotherapy.

A search and narrative review of prospective clinical trials relating to neurological toxicity outcomes was conducted.

Neurological toxicities can be challenging to diagnose and manage and should be considered during consideration of radiotherapy in brain metastasis, hence more emphasis should be placed on prevention and upfront mitigation of these complications, with novel strategies showing promising results in prospective trials being adopted into clinical practice.

Sasang constitutional medicine (SCM), which categorizes humans into four Sasang types according to their constitution-specific characteristics, has been identified as being useful in predicting metabolic risks and preventing non-communicable diseases (NCDs). However, no systematic review has evaluated this relationship previously. This study protocol describes a method for evaluating the association between Sasang constitution and the metabolic risk factors for NCDs.

The following nine academic databases will be used as data sources for entries Medical Literature Analysis and Retrieval System Online, Excerpta Medica database, Web of Science, and six Korean databases. All cohort, case-control, and cross-sectional studies that were published by December 2021 and could explain the association between Sasang constitution and metabolic risk factors for NCDs will be considered eligible. Two independent researchers will select studies, extract data, assess quality of studies, and qualitatively evaluate clinical evidence, subsequently. The quality assessment will be evaluated using the Newcastle-Ottawa Scale, with modifications if necessary. Quantitative data will be synthesized as a random-effects model, if applicable. The strength of clinical evidence will be performed applying the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) or GRADE-Confidence in Evidence from Reviews of Qualitative research approach.

This study will contribute to helping clinicians and health authorities detect any relevant metabolic risks that patients may have, based on systematic clinical evidence.

Dexmedetomidine is a potent adrenergic alpha-2 receptor agonist. It was first approved for sedation for mechanically ventilated patients. Being a sedative medication that is not associated with respiratory depression and holding analgesic properties fosters the interest for this drug in the palliative care field. The primary objectives of this review were to identify the key indications for the real-world use of dexmedetomidine in palliative care and other disciplines.

A narrative review after extensive PubMed search was performed from 1950 to present on October 21st 2021. The language of the publications was restricted to English, German, French and Italian.

(I) Current dexmedetomidine use. There is a growing body of evidence that dexmedetomidine may reduce the incidence and severity of delirium, reduce opioid-consumption and postoperative nausea in intensive care settings. It is also used to facilitate withdrawal from different substances (alcohol, opioids, heroin). Concerning safety aspects of the drsity and agitation. Especially the unique "conscious sedation" or "awake sedation" that allows patients to arouse easily under sedation and report comfort or distress was discussed by the authors.

In this review, we present the main findings for dexmedetomidine from palliative care settings and other disciplines. The potential benefits and criticalities of the drug are discussed and practical recommendations for its use are provided.
