Tongue squamous cell carcinoma (TSCC) is a malignant tumor. Long noncoding RNAs (lncRNAs) have been proved to be involved in the regulation of the progression of various cancers. However, the mechanism of lncRNA urothelial cancer-associated 1 (UCA1) in the progression of TSCC remains unclear. The expression levels of UCA1, microRNA-138-5p (miR-138-5p), and CC chemokine receptor 7 (CCR7) were measured by quantitative real-time polymerase chain reaction (qRT-PCR). The proliferation, migration, and invasion were detected using colony formation assay and transwell assay, respectively. Western blot (WB) analysis was used to test the levels of proliferation and metastasis-related proteins and CCR7 protein. Moreover, the extracellular acidification rate (ECAR) of cells was measured by the Seahorse XF Extracellular Flux Analyzer, and the adenosine triphosphate (ATP) level, glucose uptake, and lactate produce of cells were tested by their corresponding assay kits. Further, the dual-luciferase reporter assay was used to confirm the interaction between miR-138-5p and UCA1 or CCR7. In addition, the effect of UCA1 on TSCC tumor growth in vivo was evaluated by animal experiments. We found that UCA1 and CCR7 were upregulated, while miR-138-5p was downregulated in TSCC tissues. Silenced UCA1 restrained the proliferation, migration, invasion, and glycolysis metabolism of TSCC cells. Similarly, knockdown of CCR7 also could suppress the progression of TSCC. Besides, UCA1 overexpression promoted TSCC progression, while this promotion effect could be reversed by CCR7 silencing. miR-138-5p could be sponged by UCA1 and could target CCR7. Additionally, miR-138-5p overexpression could reverse the promotion effect of overexpressed UCA1 on TSCC progression. Furthermore, the UCA1 knockdown reduced TSCC tumor growth in vivo. In conclusion, lncRNA UCA1 might function as an oncogene in TSCC through regulating the miR-138-5p/CCR7 axis, providing a new biomarker for TSCC treatment.MicroRNA (miR)-103a-3p has been shown to be involved in the development and progression of several types of cancer. However, the role of miR-103a-3p in thyroid cancer remains unclear. This study investigated the effects of miR-103a-3p on the biological characteristics of thyroid cancer cells and related mechanisms. In the present study, we found that the expression of miR-103a-3p was increased in thyroid cancer tissues compared to that in non-cancerous tissues. Additionally, the expression of miR-103a-3p in thyroid cancer cell lines (TPC-1, SW579, BHT101, K1) was markedly higher than that in the human thyroid cell line (Nthy-ori3-1). Silencing of miR-103a-3p obviously inhibited proliferation, migration, and invasion and promoted apoptosis of BHT101 cells. miR-103a-3p upregulation promoted the proliferation, migration, and invasion and inhibited apoptosis of K1 cells. Mechanistically, LATS1 was identified as a functional target of miR-103a-3p, and miR-103a-3p negatively regulated LATS1 expression. miR-103a-3p knockdown (or upregulation) partially reversed the effects of LATS1 knockdown (or overexpression) on proliferation, apoptosis, migration, and invasion of thyroid cancer cells. LATS1 knockdown inhibited the phosphorylation of YAP in BHT101 cells and promoted the nuclear translocation of YAP. Whereas, miR-103a-3p downregulation reversed the inhibitory effect of LATS1 knockdown on the Hippo signaling pathway. Moreover, overexpression of LATS1 induced YAP phosphorylation in K1 cells and inhibits nuclear translocation of YAP, and the upregulation of miR-103a-3p reversed this effect. The knockdown of miR-103a-3p inhibited tumor growth and progression in vivo. Taken together, knockdown of miR-103a-3p inhibits proliferation, migration, and invasion and promotes apoptosis of thyroid cancer cells through the Hippo signaling pathway by upregulating LATS1.Sentinel lymph node biopsy (SLNB) has emerged as an alternative to axillary lymph node dissection during breast cancer surgery during the last 2 decades. However, there are several controversies regarding the indication of the sentinel node biopsy after neoadjuvant chemotherapy which can convert positive lymph nodes to negative. The false-negative rate after neoadjuvant chemotherapy is unacceptably high. This high false-negative rate can be decreased by marking of the positive lymph nodes and removal during sentinel lymph node biopsy procedure in addition to the sentinel lymph nodes. The aim of this study was to investigate the possibility of carbon tattooing of the positive sentinel lymph nodes before neoadjuvant chemotherapy. In 2016, a prospective protocol was launched investigating the black carbon tattooing procedure of the suspective and positive axillary lymph nodes by injecting 0.1-0.5 carbon ink in normal saline under ultrasound guidance. All patients underwent black carbon tattooing of the suspectedresponds to 17.4%. In the group of patients undergoing primary surgery, in one case from six, the sentinel lymph node was negative and the lymph node marked with carbon ink positive which represents false-negative lymph node and failure of the SLNB procedure. After neoadjuvant chemotherapy, there was no false-negative lymph node identified, but the conversion of the positive lymph nodes to negative was present in 10 cases (50%). There were no complications attributed to carbon ink tattooing. The results of positive sentinel lymph nodes tattooing have confirmed that this method is safe and allows a decrease in the false negativity rate during the sentinel node biopsy procedure.Siglec-15 (S15) is another important mechanism of tumor immune escape besides the PD-L1/PD-1 pathway and represents a new kind of immune checkpoint inhibitor. However, the associations of tumor Siglec-15 expression with clinicopathological characteristics and outcomes of non-small cell lung cancer (NSCLC), and tumor-infiltrating lymphocytes (TILs) in a tumor microenvironment (TME) have so far been unclear. A total of 324 NSCLC surgical samples on tumor microarray were used in this study for investigating the association of S15 expression with clinicopathological characteristics and overall survival (OS) as well as correlation with TILs using multiplex immunofluorescence staining and PD-L1. Results showed that the expression of S15 in adenocarcinoma was significantly higher than that in squamous cell carcinoma. S15 expression was positively correlated with CD8+ T cell density in the stroma. selleck compound The expression rate of PD-L1 in lung squamous cell carcinoma was higher than that in lung adenocarcinoma. S15 expression was not associated with the prognosis of early NSCLC. The pathological mechanism of the co-expression of S15 and PD-L1 in resectable NSCLC remains to be further studied.
Mortality following acute myocardial infarction (AMI) remains high despite of progress in invasive and noninvasive treatments.

This study aimed to compare the outcomes of ambulatory treatment provided by cardiologists versus general practitioners (GPs) in post‑AMI patients.

We conducted a systematic search in 3 electronic databases for interventional and observational studies that reported all‑cause mortality, mortality from cardiovascular causes, stroke, and myocardial infarction at long‑term follow‑up following AMI. We assessed the risk of bias of the included studies using the Risk of Bias in Nonrandomized Studies of Interventions (ROBINS‑I) tool. For randomized trials, we used the revised Cochrane risk of bias tool (RoB 2.0).

Two nonrandomized studies fulfilled the inclusion criteria. We assessed these studies as having a moderate risk of bias. We did not pool the results owing to significant heterogeneity between the studies. Patients consulted by both a cardiologist and a GP were at lower risk obetween the specialization of the physician and the risk of cardiovascular death, stroke, or myocardial infarction in AMI survivors.
The treatment effects of antiviral agents, glucocorticoids, antibiotics, and intravenous immunoglobulin are controversial in patients with coronavirus disease 2019 (COVID‑19).

This study aimed to evaluate the impact of drug therapy on the risk of death in patients with COVID‑19.

The PubMed, Embase, Web of Science, Cochrane Library, and major preprint platforms were searched to retrieve articles published until April 7, 2020. Subsequently, the effects of specific drug interventions on mortality of patients with COVID‑19 were assessed. Odds ratios (ORs) and relative risks (RRs) with corresponding 95% CIs were pooled using random effects models.

Of 3421 references, 6 studies were included. Pooled results from retrospective studies revealed that antiviral agents may contribute to survival benefit (OR, 0.42; 95% CI, 0.17-0.99; P = 0.048; I2 = 82.8%), whereas a single randomized controlled trial found no effects of an antiviral agent on mortality (RR, 0.77; 95% CI, 0.45-1.3; P = 0.33). Glucocorticoid use led to an increased risk of death (OR, 2.43; 95% CI, 1.44-4.1; P = 0.001; I2 = 61.9%). Antibiotics did not significantly affect mortality (OR, 1.13; 95% CI, 0.67-1.89; P = 0.64; I2 = 0%). Similarly, intravenous immunoglobulin had a nonsignificant effect on mortality (OR, 2.66; 95% CI, 0.72-9.89; P = 0.14; I2 = 93.1%).

With the varied heterogeneities across interventions, the current evidence indicated a probable survival benefit from antiviral agent use and a harmful effect of glucocorticoids in patients with COVID‑19. Neither any of antibiotics nor intravenous immunoglobulin were associated with survival benefit in this population.

Observations in the Netherlands are in line with these data. COVID-19 struck hard in the eastern part of the province of Brabant, where levels of fine particulate matter and ammonia are relatively high due to intensive livestock farming. Mechanisms by which air pollution might facilitate SARS-CoV-2 infection include a possible link between upregulation of the angiotensin converting enzyme receptor by air pollution and the host being prone to more severe COVID-19. Although the data are not yet peer-reviewed and the potential association does not necessarily imply causality, these data do stress the need for further investigation. If air pollution plays a role in the severity of the corona pandemic, more vigorous legislation concerning air quality is pivotal.For many yearsthere has been confusion in the Netherlands about the question of whether doctors are entitled to end the life of incompetent patients with advanced dementia. The euthanasia control commission, the disciplinary courts and the penal court all answered this question differently after a doctor had performed euthanasia on a 74-year-old woman with advanced dementia and an advance directive made at an earlier stage. On 21 April 2020 the Supreme Court provided clarity, at least to a certain extent. This contribution presents an analysis of the decisions made by the Supreme Court and their implications for self-chosen death in patients with advanced dementia.
