BACKGROUND AND IMPORTANCE: Stent-assisted coil embolization has been established as a treatment option for wide-necked or complex aneurysms. However, concerns have been raised about the incidence of thromboembolic complications, which is higher for coil embolization without stent assistance. Long-term antiplatelet therapy is necessary to prevent acute or delayed ischemic events potentially associated with incomplete stent apposition after treatment with stent-assisted coil embolization...

The demand of favorable scaffolds has increased for the emerging cartilage tissue engineering. Chondroitin sulfate (CS) and silk fibroin have been investigated and reported with safety and excellent biocompatibility as tissue engineering scaffolds. However, the rapid degradation rate of pure CS scaffolds presents a challenge to effectively recreate neo-tissue similar to natural articular cartilage. Meanwhile the silk fibroin is well used as a structural constituent material because its remarkable mechanical properties, long-lasting in vivo stability and hypoimmunity...

This report describes a patient who presented with a large gallstone obstructing the duodenal bulb, with the chief complaint of acute on chronic abdominal pain. Classically, this is known as Bouveret's syndrome or a gallstone ileus of the duodenum. Our patient's current health status presented a challenge, with the presence of several comorbidities, particularly a large abdominal aortic aneurism. We chose an open procedure for this reason. The stone was removed through a laparotomy, and the cholecystoduodenal fistula that the stone used to pass into the small bowel was repaired...

BACKGROUND: Critical limb ischemia (CLI) may be the consequence of chronic occluded popliteal artery aneurysm (PAA). Open repair (OR) offers better 5-year results than endovascular treatment, but in patients with severe comorbidities or unfit to OR, endovascular repair (ER) could represent a valid treatment option. The purpose of this retrospective study was to review our experience of endovascular popliteal aneurism repair (EVPAR) in patients with chronic occluded PAA. METHODS: The endpoints assessed were: 1- and 3-year primary and secondary patency rates, technical success, 30-day major adverse events, major amputation free-survival, re-intervention and survival rates...

Firstly described in the 19th century by Sir William Osler, the mycotic aneurysm (MA) is a rare entity characterized by an abnormal arterial dilation, which is potentially fatal, and is associated with the infection of the vascular wall. Elderly patients are mostly involved, especially when risk factors like chronic diseases, immunosuppression, neoplasia, and arterial manipulation are associated. The authors report the case of a young male patient diagnosed with an aortic aneurysm of infectious origin in the presence of repeated negative blood cultures...

Fibromuscular dysplasia (FMD) commonly affects the renal and cervical arteries but has been described to affect other vascular beds as well. The prevalence of and clinical characteristics associated with multisite FMD (string-of-beds or focal stenoses affecting at least 2 vascular beds) are not known. In the prospective ARCADIA registry (Assessment of Renal and Cervical Artery Dysplasia), symptomatic patients with renal artery (RA) FMD underwent tomographic- or magnetic resonance-angiography from the aortic arch to the intracranial arteries and those with cervical FMD from the diaphragm to the pelvis...

Extra-renal complications of autosomal dominant polycystic kidney disease (ADPKD) are often unrecognized. Liver cysts are usually benign, but may cause chronic pain, may interfere with nutrition and may necessitate partial liver resection or even liver transplant. Somatostatin analogs may be an alternative therapy. Cerebral aneurisms are rare, but devastating. They must be investigated in case of positive familial history. Cardiac valvulopathies will be searched for by echocardiography. Abdominal wall herniae are often identified during the physical exam in ADPKD patients...

Skeletal muscle tissues engineered in vitro are aneural, short in number of fibers required to function properly, and degenerate rapidly. Electrical stimulation has been widely used to compensate for such lack of neural activity, yet the relationship between the stimulation parameters and the tissue response is subject of debate. Here we study the effect of overnight electrical stimulation (training) on the contractility and maturity of aligned C2C12 myotubes developed on micropatterned gelatin methacryloyl (GelMA) substrates...

Visceral arteries aneurysms (VAA) are an increasingly interesting clinical entity due to their challenging diagnosis and treatment options. The more prevalent use and accuracy of enhanced imaging techniques such as ultrasonography and computed tomography have increased the frequency of diagnosis of aneurysmal degeneration of the visceral arteries. Despite there is no statistically significant difference in terms of overall mortality and post-operative complications between endovascular therapy and open repair, interventional strategies present a significantly lower length of stay and less invasiveness and should be preferred in elderly patients, or in case of co-morbidity and poor candidates for surgery...

BACKGROUND: Several benefits have been described over the years of the transradial versus femoral endovascular approach to cardiac interventions. Consequently, its use has become habitual at most centers that perform cardiac catheterizations. This paper details a right transradial approach, incorporating a variety of coils or flow diverters, which can be utilized for the endovascular treatment of different cerebral aneurysms. METHODS: From 2014 to 2016, we performed 40 endovascular procedures to treat cerebral aneurysms adopting the same right transradial approach...

Autosomal dominant polycystic kidney disease is the most frequent hereditary kidney disease. Intracranial aneurysm prevalence in this population is four to five times higher than the prevalence in the general population. The most frequent complication of intracranial aneurysms is rupture with subarachnoidal hemorrhage, which is associated with a high morbidity and mortality. The only identified risk factor for unruptured intracranial aneurysm is a family history of intracranial aneurysm. However, most cases of aneurysm rupture occur without any family history of intracranial aneurysm...

Cartilage is an avascular, aneural, and alymphatic connective tissue with a limited capacity caused by low mitotic activity of its resident cells, chondrocytes. Natural repair of full thickness cartilage defects usually leads to the formation of fibrocartilage with lower function and mechanical force compared with the original hyaline cartilage and further deterioration can occur. Tissue engineering and regenerative medicine is a promising strategy to repair bone and articular cartilage defects and rehabilitate joint functions by focusing on the optimal combination of cells, material scaffolds, and signaling molecules...

BACKGROUND: The transposition of the great arteries (TGA) is one of the most severe congenital heart diseases. The arterial switch operation (ASO) is the preferred procedure to treat TGA. Although numerous reports have shown good results after ASOs, some patients suffer from circulatory system problems following the procedure. One reason for problems post-ASO is the local changes in the curvature and torsion of the thoracic aorta. OBJECTIVE: The influence of these geometric changes on the blood flow field needs to be investigated in detail to consider possible cardiovascular problems after an ASO...

INTRODUCTION: Subarachnoid hemorrhage (SAH)represents hemorrhage in the space between arachnoidea and pia mater, due to aneurysm burst, spontaneously or as a consequence of trauma. It is condition that occurs more common in women than men, and its most common complications are rebleeding and vazospasm. As a result of vasospasm, develops ischemia in the portion of brain tissue that can cause additional neurological deficit. Transcranial Doppler Sonography (TCD) is a noninvasive ultrasound diagnostic method that allows monitoring of the state of intracerebral hemodynamics...

Marc van Duijn
Various forms of elementary learning have recently been discovered in organisms lacking a nervous system, such as protists, fungi and plants. This finding has fundamental implications for how we view the role of convergent evolution in biological cognition. In this article, I first review the evidence for basic forms of learning in aneural organisms, focusing particularly on habituation and classical conditioning and considering the plausibility for convergent evolution of these capacities. Next, I examine the possible role of convergent evolution regarding these basic learning abilities during the early evolution of nervous systems...

Overdiagnosis is a growing problem worldwide. Overdiagnosis is the diagnosis of deviations, abnormalities, risk factors, and pathologies that in themselves would never cause symptoms (this applies only to risk factors and pathology), would never lead to morbidity, and would never be the cause of death. Overdiagnosis is often misinterpreted as overutilization or overtreatment. Overutilization, overtreatment, and overdiagnosis are interrelated but three distinct topics. Overutilization (establishment of standard practice that does not provide net benefit) does not have to lead to overdiagnosis or overtreatment, but the risk exists...
