Aim: The aim of this article is to determine vasoactive intestinal peptide (VIP) levels outside migraine attacks in peripheral blood as a potential biomarker for chronic migraine (CM).
Methods: Women older than 17 and diagnosed as CM were recruited. Matched healthy women with no headache history and women with episodic migraine (EM) served as control groups, together with a series of patients with episodic cluster headache in a pain-free period. VIP levels were determined in blood samples obtained from the right antecubital vein by ELISA outside a migraine attack, the patients having taken no symptomatic medication the day before. For ethical reasons, preventives were not stopped.
Results: We assessed plasma samples from 119 women with CM, 33 healthy women, 51 matched women with EM and 18 patients (16 males) with cluster headache matched for age. VIP levels were significantly increased in CM (165.1 pg/ml) as compared to control healthy women (88.5 pg/ml) and episodic cluster headache patients (101.1 pg/ml). VIP levels in EM (134.9 pg/ml) were significantly higher compared to controls and numerically lower than those of CM. Thresholds of 71.8 and 164.5 pg/ml optimized the sensitivity and specificity to differentiate CM from healthy controls and EM, respectively. Variables such as age, CM duration, the presence of aura, analgesic overuse, depression, fibromyalgia, vascular risk factors, history of triptan consumption or kind of preventive treatment did not significantly influence VIP levels.
Conclusion: Increased interictal VIP level measured in peripheral blood could be a biomarker helping in CM diagnosis, though it does not clearly differentiate between EM and CM.

Background: Triglyceride-glucose (TyG) index was regarded as a cost-efficient and reliable clinical surrogate marker for insulin resistance (IR), which was significantly correlated with cardiovascular disease (CVD). However, the TyG index and incident CVD in non-diabetic hypertension patients remains uncertain. The aim of study was to explore the impact of TyG index level and variability on risk of CVD among non-diabetic hypertension patients.

Objective: High D-dimer levels may increase the likelihood of unfavorable clinical outcomes in patients with acute ischemic stroke. However, the impacts of serum D-dimer levels on outcomes of reperfusion treatment in patients with acute ischemic stroke have not been evaluated. This study aims to assess a possible relationship between serum D-dimer and functional outcomes in stroke patients with endovascular treatment (EVT).

Nutritional status is associated with prognosis in a variety of cancers. Studies analyzing the association between the measurements of skeletal muscle and adipose tissue obtained from Computerized Tomography (CT) images at the time of diagnosis of advanced non-small cell lung cancer (NSCLC) and overall survival (OS) are relatively few. Data from 425 patients diagnosed with advanced NSCLC between January 2016 and December 2017 were retrospectively analyzed, with an average follow-up of 15.

This study aims to investigate the potential of phenylacetylglutamine as a biomarker for major adverse cardiovascular events (MACEs) of patients with STEMI and MVCD.
Methods And Results: Clinical data and blood samples were collected from 631 patients with STEMI and MVCD, who underwent primary percutaneous coronary intervention.
