BACKGROUND Mesenteric vein thrombosis (MVT) is uncommon and accounts for 5-10% of all mesenteric ischemic events. In 80% of cases, an etiologic factor is found. The clinical presentation varies and the diagnosis is made based on imaging studies. The treatment involves anticoagulation alone or in combination with surgery. AIM To describe the clinical characteristics of patients with MVT. PAT...

Patients with an implantable cardioverter-de~brillator (ICD) may receive frequent shocks or antitachycardia pacing for monomorphic ventricular tachycardia (MVT) despite suppressive drug therapy. Antitachycardia pacing is often well-tolerated but not always effective. High voltage cardioversion is usually painful and may cause severe, disabling anxiety for some patients. Therefore, catheter abla...

Previous evidence has shown that vagal nerve activity modulates ventricular arrhythmias in patients and in animal models. However, the effects of direct vagus nerve stimulation on ventricular tachyarrhythmias brought by direct sympathetic nerve stimulation have not been elucidated. In the present study, the effects of electrical stimulation of the left cervical vagus nerve on ventricular tachyc...

3 We integrate appealing features of Markowitz’s mean-variance portfolio theory (MVT) 4 and Shefrin and Statman’s behavioral portfolio theory (BPT) into a new mental accounting 5 (MA) framework. Features of the MA framework include an MA structure of portfolios, 6 a definition of risk as the probability of failing to reach the threshold level in each mental 7 account, and attitudes toward risk ...

BACKGROUND Although multivitamin products are widely used as dietary supplements to maintain health or as special medical food in certain diseases, the effects of these products were not investigated in diabetes mellitus, a major cardiovascular risk factor. Therefore, here we investigated if a preparation of different minerals, vitamins, and trace elements (MVT) for human use affects the severi...

Serial stay-or-search problems are ubiquitous across many domains, including employment, internet search, mate search, and animal foraging. For instance, in patch foraging problems, animals must decide whether to stick with a depleting reward vs search for a new source. The optimal strategy in patch foraging problems, described by the Marginal Value Theorem (MVT; Charnov, 1976), is to leave the...

Acute mesenteric venous thrombosis (MVT) is an uncommon form of intestinal ischemia with high mortality and usually occurs in the setting of preexisting comorbidities including thrombophilia and abdominal inflammatory conditions. Hyperhomocysteinemia has been known to be a risk factor for thromboembolism, often located on an unusual site. Considering that homocysteine metabolism is determined g...

Prospective studies using video-recordings of patients during mechanical ventilator treatment (MVT) while conscious have not previously been published. The aim was to describe patients' statements, communication and facial expressions during a video-recorded interview while undergoing MVT. Content analysis and hermeneutics inspired by the philosophy of Gadamer were used. The patients experience...

Heating-induced micelle to vesicle transition (MVT), which has been rarely reported in surfactant systems, was systemically studied in a number of mixed cationic-anionic surfactant systems. According to the turbidity measurements, the investigated systems can be divided into two classes: Class A and B. Heating-induced MVT was observed in Class A at certain total surfactant concentrations and mi...

Otitis media is often treated surgically through the use of a procedure termed myringotomy with insertion of a ventilation tube (MVT). From fiscal year 1992/3 to 1997/8, some 132,000 such operations were performed in Ontario, Canada, on young people < 20 years old. This study quantifies the small area variation (SAV) in MVT surgical rates across the 49 counties and 478 postal areas of Ontario; ...
