Nomogram for Predicting In-Hospital Mortality in Patients with Acute ST-Elevation Myocardial Infarction Complicated by Cardiogenic Shock after Primary Percutaneous Coronary Intervention

Yudan Wang, Litian Liu, Xinning Li et al. · 2022 · Journal of Interventional Cardiology

Background: Mortality after percutaneous coronary intervention (PCI) in ST-elevation myocardial infarction (STEMI) patients with cardiogenic shock (CS) remains high. However, the real-world risk factors for mortality in these patients are poorly defined. Objective: The aim of this study is to establish a clinical prognostic nomogram for predicting in-hospital mortality after primary PCI in STEMI patients with CS. Methods: This retrospective, multicenter, observational study included STEMI patients with CS who underwent PCI at 39 hospitals in Hebei Province from January 2018 to December 2019. A

A comprehensive evaluation of early potential risk factors for disease aggravation in patients with COVID-19

Qiang Tang, Yanwei Liu, Yingfeng Fu et al. · 2021 · Scientific Reports

The 2019 Coronavirus Disease (COVID-19) has become an unprecedented public crisis. We retrospectively investigated the clinical data of 197 COVID-19 patients and identified 88 patients as disease aggravation cases. Compared with patients without disease aggravation, the aggravation cases had more comorbidities, including hypertension (25.9%) and diabetes (20.8%), and presented with dyspnoea (23.4%), neutrophilia (31.5%), and lymphocytopenia (46.7%). These patients were more prone to develop organ damage in liver, kidney, and heart (P < 0.05). A multivariable regression analysis showed that adv

A phase II study of ENMD-2076 in advanced soft tissue sarcoma (STS)

Zachary Veitch, Alona Zer, Herbert H. Loong et al. · 2019 · Scientific Reports

ENMD-2076, an aurora-A kinase inhibitor with anti-angiogenic properties, has shown activity in solid and hematologic malignancies. We investigated oral ENMD-2076 in an open-label, single-arm phase II study using 275 mg daily on a 28-day cycle in patients with advanced soft-tissue sarcomas (STS) receiving ≤1 line of prior therapy. Primary endpoint was 6-month progression-free survival (PFS) with ≤15% indicating no interest, and ≥40% indicating further interest in ENMD-2076. Secondary/exploratory endpoints included clinical benefit (CBR ≥6-months) and objective response (ORR) rates, PFS, OS, saf

Addition of chemotherapy to intensity-modulated radiotherapy does not improve survival in stage II nasopharyngeal carcinoma patients

Fangzheng Wang, Jiang Chuner, Quanquan Sun et al. · 2018 · Journal of Cancer

In this study, we examined whether combining neoadjuvant chemotherapy (NAC) and/or concurrent chemotherapy (CC) with intensity-modulated radiotherapy (IMRT) improved survival in patients with stage II nasopharyngeal carcinoma (NPC). Two hundred forty-two stage II NPC patients were enrolled between May 2008 and April 2014 and received radical IMRT with simultaneous integrated boost technique using 6 MV photons; some patient groups also received chemotherapy every 3 weeks for 2-3 cycles. The median follow-up duration was 69 months for all patients. At the last follow-up, 18 patients had experien

The effects of amiodarone prophylaxis on cardiac dysrhythmia in acute aluminium phosphide poisoning

Mohammad Reza Beyranvand, Soleyman Farrokhi, Hassan Peyvandi et al. · 2019 · Archives of Industrial Hygiene and Toxicology

Cardiovascular toxicity is the most common cause of fatality in the first 24 hours of poisoning with aluminium phosphide (AlP). Most often manifesting itself in cardiac dysrhythmias. The aim of this study was to evaluate the benefits of amiodarone prophylaxis against cardiac dysrhythmia in 46 patients with acute AlP poisoning. They were divided in two groups of 23: one receiving amiodarone and the other not (control). The treatment group received amiodarone prophylaxis in the initial intravenous bolus dose of 150 mg, followed by a drip of 1 mg/min for six hours and then of 0.5 mg/min for eight
