National Variations Generalized Panic Through the COVID-19 Pandemic amongst Brazil University Students: a National Questionnaire.
Almost all patients with stages II and III accepted surgery. Patients who underwent surgery to treat their colorectal cancer had longer survival than those who did not.

Old age should not be a reason for giving up treatment for colorectal cancer. The treatment of colorectal cancer patients aged 80 years and above requires individualized evaluation and more aggressive treatment to achieve greater benefits.

Colorectal cancer (CRC) is one of the most common cancers. The aim of our study was to explore its related mutations, identify novel mutation markers, and construct predictive models for postoperative CRC patients, so as to provide evidence for the diagnosis, treatment, and prognosis of CRC.

A total 50 CRC patients were collected, and the mutations in tissue samples were detected through next-generation sequencing (NGS). Meanwhile, 246 CRC cases with complete mutation data were downloaded from The Cancer Genome Atlas (TCGA) database. Afterwards, the co-mutations in both clinical and TCGA cohorts were identified, and the high-frequency mutation genes were selected. Subsequently, functional enrichment analysis was performed, and overall survival (OS) and progression-free survival (PFS) predictive models were constructed.

In all, 18 out of 238 co-mutation genes mutated in at least 20% of the samples and were selected out as common high-frequency mutation genes. They were significantly enriched in 460 Gene d PFS of CRC patients.
Polyps may develop into colorectal cancer (CRC) after 10-20 years. The occurrence of polyps and tumors caused by somatic gene mutations is considered a main pathogenesis of CRC. Among all general patients with polyps or CRC, some had adenoma of varying degrees that were consistent with familial colorectal adenomas. A patient with CRC (the propositus) and his brothers and sister, all of whom had varying degrees of colorectal polyps showed different adenomas with different members in a family.

In the present study, a total of 9 family members were investigated, and a family tree was drawn. Genomic DNA was extracted from peripheral venous blood samples from family members, and whole-exome sequencing (WES) and Sanger sequencing were performed on the DNA samples. The result of WES was compared with compared directly to the reference genome (hg19) with Burrows-Wheeler Aligner, which is as control group from.

We identified a base substitution in the
gene (c.68415368T>G, chromosome 9 q13), predicted the t
gene may represent a key gene mutation in colorectal carcinogenesis and a multiyear cancer risk for patients that requires further attention.
The mutation of the has-mir-4477b gene likely leads to the occurrence of adenoma and CRC. In-depth studies of patients from the same family with different stages of adenoma can avoid errors caused by gene diversity, incomplete clinical data, and uncertain disease development. The has-mir-4477b gene may represent a key gene mutation in colorectal carcinogenesis and a multiyear cancer risk for patients that requires further attention.
Multipotent mesenchymal stem cells (MSCs) derived from virus tumors have been reported to contribute to malignant cell growth, invasion, and metastasis. However, the mechanism of communication between MSCs and colon cancer cells is poorly understood. Recent studies have suggested that exosomes are an important player in crosstalk between cells and could significantly suppress the invasion ability of human cancer cells (hCCs) when transfected with a microRNA inhibitor. However, to date, no study has illuminated the miRNA changes in exosomes derived from hCC-MSCs.

Colon cancer stem cells were cultured in medium and passaged to develop fibroblast-like morphology. Exosomes were collected using ExoQuick precipitation and exosome morphology was visualized by transmission electron microscopy. Small RNA sequencing was analyzed using an Illumina HiSeq4000 analyzer, and the expression of MIA3 was assessed by real-time PCR and Western blot. The functional roles of miR-30a and miR-222 in colon cancer cells were evalu expression, and promote colon cell proliferation, migration, and metastasis.
These data suggest that hCC-MSC-secreted exosomes promote colon cancer cell proliferation and metastasis through delivering miR-30a and miR-222. Subsequently, exosomal miR-30a and miR-222 simultaneously target MIA3, suppress its expression, and promote colon cell proliferation, migration, and metastasis.
As an immune checkpoint that suppresses antitumor immunity, CD276 is a potential therapeutic target for cancer immunotherapy. However, the role of CD276 in esophageal squamous cell carcinoma (ESCC) has not been thoroughly examined. A greater understanding of the regulatory mechanism of CD276 may improve the clinical response and efficacy of cancer immunotherapy.

The expression of CD276 was measured by qRT-PCR, IHC and flow cytometry analysis. T cell infiltration in ESCC was measured by qRT-PCR and immunofluorescence analysis. The regulation function of CD276 in glucose metabolism was examined by metabolism assays, western blotting and small molecule inhibitors. Transfection was used for gene editing. The oncogenic function of CD276 was examined in vivo by CAR-T cell therapy model.

Based on our findings, CD276 regulated the expression of the
gene in ESCC. WZB117 Overexpression of CD276 induced the phosphorylation of PKM2 by the STAT3 signalling pathway to promote glucose metabolism in tumors. The accumulatioimmunotherapy of ESCC patients.
To evaluate the short-term efficacy of azygos arch-sparing McKeown minimally invasive esophagectomy (McKeown-MIE).

We retrospectively analyzed the clinical data of 221 patients with thoracic esophageal squamous cell carcinoma who underwent McKeown-MIE at the Department of Thoracic Surgery of Gaozhou People's Hospital from August 1, 2017 to September 30, 2019. According to whether the azygos arch was preserved or not, the patients were assigned to one of two groups the preservation group (40 cases) and the ligation group (181 cases). Within 3 months of the operation, the perioperative outcomes and the postoperative short-term efficacy of the two groups were compared.

After propensity score (PS) matching, 40 pairs of patients were matched successfully. Between the two groups, there were no statistical difference in intraoperative blood loss, the number of lymph nodes dissected, thoracic drainage duration, fasting time, postoperative hospital stay time, and major postoperative complications (P>0.05). Compared with the ligation group, patients in the preservation group had a shorter intensive care unit (ICU) stay time, a shorter operative time, a lower volume of postoperative thoracic drainage (both the first 3 days and overall) following surgery, a tubular stomach that had a smaller caliber, and a lower incidence of tubular gastric malpositioning (P<0.05).

Preserving the azygos arch during a McKeown-MIE is safe and feasible. Doing so, not only effectively restricts the expansion of the gastric conduit, leading to a lower incidence of malpositioning, but also dramatically reduces postoperative thoracic drainage, and ICU stay time.

The Competing endogenous RNA (CeRNA) network plays important roles in the development and progression of multiple human cancers. Increasing attention has been paid to CeRNA in esophageal carcinoma (ESCA).

We explored The Cancer Genome Atlas (TCGA) database and then analyzed the RNAs of 142 samples to obtain long non-coding RNAs (lncRNAs), micro RNAs (miRNAs), and messenger RNAs (mRNAs) with different expression trends alongside the progress of ESCA. A series test of cluster (STC) analysis was carried out to identify a set of unique model expression tendencies. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis were used to validate the function of key genes that were obtained from the STC analysis.

Through our analysis, 272 lncRNAs, 87 miRNAs, and 692 mRNAs showed upward expression or downward expression trends, and these molecules were tightly involved in cell cycle, pathways in cancer, metabolic processes, and protein phosphorylation, among others. Ultimately, we constructed a CeRNA network containing a total of 71 lncRNAs, 56 miRNAs, and 125 mRNAs. The overall survival (OS) was analyzed using univariate Cox regression analysis to clarify the relationship between these key molecules from the CeRNA network and the prognosis of ESCA patients. Through survival analysis, we finally screened out two lncRNAs (DLEU2, RP11-890B15.3), three miRNAs (miR-26b-3p, miR-92a-3p, miR-324-5p), and one mRNA (SIK2) as crucial prognostic factors for ESCA.

The novel CeRNA network that we constructed will provide new novel prognostic biomarkers and therapeutic targets for patients with ESCA.

Neoadjuvant therapy followed by esophagectomy has been recognized as an effective treatment for locally advanced esophageal cancer, though still has a dismal prognosis. Antibodies against programmed death 1 (PD-1) protein improve survival in patients with advanced or metastatic esophageal squamous cell carcinoma (ESCC) compared with chemotherapy in second-line therapy. However, neoadjuvant PD-1 inhibitor combined with chemotherapy has not been tested in locally advanced ESCC. We conducted this study to evaluate the efficacy and safety of pd-1 inhibitor in neoadjuvant chemotherapy.

In this study, we administered 28 adults with untreated, surgically resectable locally advanced ESCC. PD-1 inhibitor with chemotherapy [albumin paclitaxel 100 mg/m
on days 1 and 8 + carboplatin with an area under the curve (AUC) of 5 on day 1] were administered every 3 weeks intravenously, and surgery was performed approximately 3-5 weeks after the second dose. The primary purpose of the study was to evaluate the feasibility aerapy, a high R0 resection rate, and a low-toxicity profile were achieved. The long-term efficiency of this novel treatment and the validity of the present findings should be confirmed with longer follow-up and prospective comparative trials.
The novel treatment of PD-1 inhibitor with chemotherapy in the neoadjuvant setting for locally advanced ESCC produced satisfactory outcomes an unprecedentedly high pCR rate for neoadjuvant chemotherapy, a high R0 resection rate, and a low-toxicity profile were achieved. The long-term efficiency of this novel treatment and the validity of the present findings should be confirmed with longer follow-up and prospective comparative trials.Acute heart failure and acute pulmonary embolism share many features, including epidemiological aspects, clinical presentation, risk factors and pathobiological mechanisms. As such, it is not surprising that diagnosis and management of these common conditions might be challenging for the treating physician, in particular when both are concomitantly present. While helpful guidelines have been elaborated for both acute heart failure and pulmonary embolism, not many studies have been published on the coexistence of these diseases. With a special focus on diagnostic tools and therapeutic options, the authors review the available literature and, when evidence is lacking, present their own approach to the management of dyspnoeic patients with acute heart failure and pulmonary embolism.
