Role of peroral endoscopic myotomy in geriatric patients with achalasia: a systematic review and meta-analysis.

Dig Dis 2021 03 22. Epub 2021 Mar 22.

Background: Peroral endoscopic myotomy (POEM) is a particularly attractive intervention for achalasia. Presently, POEM has been reported to be effective and safe for achalasia in geriatric patients. Herein, this systematic review was conducted to explore the role of POEM in geriatric patients with achalasia.

Method: PubMed, Embase and Cochrane Library were searched to identify studies evaluating the clinical outcome of POEM in geriatric patients with achalasia during January 2009 to October 2020. The primary outcomes were technical and clinical success. Secondary outcomes included postoperative Eckardt score, lower esophageal sphincter (LES) pressure, adverse events and clinical reflux.

Results: There were seven studies with a total of 469 geriatric patients, pooled technical success of POEM treatment was 98.1% [95% confidence interval (CI), 95.1%-99.3%], and the pooled clinical success was 92.5% (95% CI, 89.3%-94.8%). After POEM, the Eckardt score significantly decreased by 6.09 points (95% CI, 5.44-6.74, P<0.00001), and the LES pressure significantly reduced by 13.53 mmHg (95% CI, 5.14-21.91, P=0.002). The pooled adverse events rate was 9.0% (95% CI, 4.3%-17.9%) and the post-POEM clinical reflux rate was 17.4% (95% CI, 12.9%-23.2%).

Conclusions: Our current study demonstrated that POEM was an effective and safe technique for achalasia in geriatric patients.

Scoping Review and Bibliometric Analysis of the Most Influential Publications in Achalasia Research from 1995 to 2020.

Biomed Res Int 2021 4;2021:8836395. Epub 2021 Feb 4.

Department of Gastroenterology, Affiliated Hospital of Southwest Medical University, Luzhou, China.

Objective: To identify and evaluate characteristics of the most influential articles in achalasia research during the period 1995-2020.

Methods: Articles in Scopus, Web of Science Core Collection (WoSCC), and PubMed were scanned from 1995 to 2020 with achalasia as the keyword. We retrieved the articles that met all criteria by descending order after using EndNote to remove the duplicated references. Our bibliometric analysis highlighted publication year, country, journals, and networks of keywords.

Results: Fifteen percent of the top 100 most-cited articles were published in They were performed in 15 countries, and most ( = 55) were from the USA. The number of citations of the 482 articles ranged from 30 to 953, 38 of which had been published in . Those articles were from 31 countries, and most of the studies ( = 217) had been performed in the USA. Most of articles ( = 335) were clinical research. Treatments were hotspots in the field of achalasia in the past years. The most influential title words were "achalasia," "esophagomyotomy," "pneumatic dilation," and "lower esophageal sphincter."

Conclusion: Our study offers a historical perspective on the progress of achalasia research and identified the most significant evolution in this field. Results showed treatment was the most influence aspect in achalasia.

Radiotherapy for one rectal cancer patient with cirrhosis and moderate to severe thrombocytopenia: a case report.

Onco Targets Ther 2018 27;11:5203-5207. Epub 2018 Aug 27.

Department of Radiation Oncology, The First Hospital of China Medical University, Shenyang, Liaoning, China,

When patients with cirrhosis and severe thrombocytopenia suffer malignant tumors, there is usually no effective and feasible treatment method due to the high risk of hemorrhage. Herein, we report a case in which radiotherapy was given to a patient with a strong desire for the treatment. The patient was a 66-year-old man with a 13-year history of cirrhosis and a 10-year history of thrombocytopenia, and was diagnosed with locally advanced rectal cancer (LARC; TNM, stage IIIB). The platelet count before radiotherapy was 32 × 10/L, and the blood coagulation was normal. The severity of thrombocytopenia increased after 2 Gy × 7 fractions pelvic radiation, with platelet counts dropping to 16 × 10/L. Platelet counts failed to return to pre-therapy levels after supporting therapy including recombinant human interleukin 11 subcutaneous injection and platelet transfusion. Although radiotherapy was discontinued eventually, the data presented here represent a valuable resource that can help inform treatment decisions for tumor patients with cirrhosis and thrombocytopenia.

Overexpression of CASS4 promotes invasion in non-small cell lung cancer by activating the AKT signaling pathway and inhibiting E-cadherin expression.

The role of Crk-associated substrate (CAS) family members in regulating invasion and metastasis has been described in several cancers. As the fourth member of the CAS family, CASS4 is also related with positive lymph node metastasis and poor prognosis in lung cancer. However, the underlying mechanisms and downstream effectors of CASS4 in the development and progression of non-small cell lung cancer (NSCLC) remain unclear. In this study, CASS4 overexpression inhibited E-cadherin expression and enhanced invasion in NSCLC cell line transfected with CASS4 plasmid, while CASS4 depletion upregulated E-cadherin expression and inhibited invasion in NSCLC cell line transfected with CASS4 siRNA. The effect of CASS4 overexpression in facilitating invasion of NSCLC cells was reversed by restoring E-cadherin expression, which indicates that CASS4 may promote invasion by inhibiting E-cadherin expression. Subsequent immunohistochemistry results confirmed that CASS4 overexpression correlated with loss of E-cadherin expression. We next investigated the phosphorylation levels of focal adhesion kinase (FAK), p38, extracellular signal-related kinase (ERK), and AKT after CASS4 plasmid or CASS4 siRNA transfection. CASS4 facilitated AKT (Ser473) phosphorylation. Treatment with an AKT phosphorylation inhibitor reversed the increased invasive capacity and downregulation of E-cadherin protein induced by CASS4 overexpression. Taken together, the present results indicate that CASS4 may promote NSCLC invasion by activating the AKT signaling pathway, thereby inhibiting E-cadherin expression.
