Accuracy of duplex ultrasonography versus angiotomography for the diagnosis of extracranial internal carotid stenosis.

Introduction: Internal carotid artery (ICA) stenosis causes about 15% of ischemic strokes. Duplex ultrasonography (DUS) is the first line of investigation of ICA stenosis, but its accuracy varies in the literature and it is usual to complement the study with another more accurate exam when faced with significant stenosis. There is a lack of studies that compare DUS with angiotomography (CTA) in the present literature.

Local climate, air quality and leaf litter cover shape foliar fungal communities on an urban tree.

Foliar fungi on urban trees are important for tree health, biodiversity and ecosystem functioning. Yet, we lack insights into how urbanization influences foliar fungal communities. We created detailed maps of Stockholm region's climate and air quality and characterized foliar fungi from mature oaks (Quercus robur) across climatic, air quality and local habitat gradients.

Interventions for thrombosed haemodialysis arteriovenous fistulas and grafts.

Background: Patients who present with problems with definitive dialysis access (arteriovenous fistula (AVF) or arteriovenous graft (AVG)) become catheter dependent (temporary access), a condition that often carries a higher risk of infections, central venous occlusions and recurrent hospitalisations. For AVG, primary patency rates are reported to be 30% to 90% in patients undergoing thrombectomy or thrombolysis. According to the National Kidney Foundation-Kidney Disease Outcomes Quality Initiative (NKF-KDOQI) guidelines, surgery is preferred when the cause of the thrombosis is a stenosis at the site of the anastomosis in thrombosed AVF.

Retrograde distal access versus femoral access for below the knee angioplasty.

Background: The prevalence of peripheral artery disease (PAD) in the general population is about 12% to 14% and it increases with age. PAD increased from 164 million people in 2000 to 202 million people in 2010. More than two-thirds of people with PAD are based in low- or middle-income countries.

Stenting or angioplasty for the treatment of deep vein thrombosis: Systematic review and meta-analysis of randomized controlled trials.

Background: Although the cornerstone treatment for deep vein thrombosis (DVT) remains anticoagulation, clinicians perform stenting or angioplasty (SA) in particular patients. To assess the effects of SA in this setting, we performed a systematic review of randomized controlled trials.

Methods: Based on the Cochrane standards, we searched the Cochrane CENTRAL, MEDLINE, Embase, CINAHL, LILACS and IBECS databases, and trial registries.

Vascular complications in 305 severely ill patients with COVID-19: a cohort study.

Background: Although an association has been made between coronavirus disease 2019 (COVID-19) and microvascular disease, data on vascular complications (other than venous thromboembolism) are sparse.

Objective: To investigate the vascular complications in severely ill patients hospitalized with COVID-19 and their association with all-cause mortality.

Design And Setting: This cohort study was conducted at the Universidade Federal de São Paulo, Brazil.

Type of anaesthesia for acute ischaemic stroke endovascular treatment.

Background: The use of mechanical thrombectomy to restore intracranial blood flow after proximal large artery occlusion by a thrombus has increased over time and led to better outcomes than intravenous thrombolytic therapy alone. Currently, the type of anaesthetic technique during mechanical thrombectomy is under debate as having a relevant impact on neurological outcomes.

Objectives: To assess the effects of different types of anaesthesia for endovascular interventions in people with acute ischaemic stroke.

External validation of Villalta score in high-middle income country patients with deep vein thrombosis.

Post-thrombotic syndrome (PTS) is a late complication that does not have a cure yet, with a prevalence estimated between 20 to 75%, associated with previous deep vein thrombosis event. Although the Villalta score (VS) is the gold-standard clinical tool for diagnostic and prognostic evaluation of PTS, there are currently no VS intra-rater agreement established and no validation studies for VS' application into Brazilian Portuguese. We sought to translate and validate VS reliability systematically; and, secondarily, to compare the ultrasound findings with the severity of PTS.

Ventilatory weaning strategies for predicting extubation success in children following cardiac surgery for congenital heart disease: a protocol for a systematic review and meta-analysis.

Introduction: Congenital heart disease (CHD) comprises the anatomic malformations that jeopardise the structure and function of the heart. It can be extremely complex and serious, corresponding to 30% of all deaths in the first month of life. The surgical approach for adequate treatment requires postoperative mechanical ventilation.

Looking for the Brain Inside the Initial Teacher Training and Outreach Books in Portugal.

The fascination with brain research is widespread, and school teachers are no exception. This growing interest, usually noticed by the increased supply of short-term training or books on how to turn the brain more efficient, leads us to think about their basic training and outreach resources available. Little is known about what the official Initial Teacher Training (ITT) offers concerning the brain literature and if it meets scientific standards.

Recommendations for use of personal protective equipment (PPE) in surgical procedures during the SARS-Cov pandemic.

Since the Coronavirus Disease 2019 was classified as a pandemic by the World Health Organization in 2019, many measures have been proposed to reduce the risks and the chances of contamination by the new coronavirus. In this context, wearing personal protective equipment is very important, especially in hospital environments and situations involving healthcare, since the degree of exposure is notably higher among the subgroup of healthcare professionals. The aim of this article is to propose a roadmap for the sequence of personal protective equipment use for surgical procedures during the coronavirus pandemic.

Two New -Alkanoyl-5-Hydroxytryptamides with Relevant Antinociceptive Activity.

In this work, we describe a new route for the synthesis and the antinociceptive effects of two new -alkanoyl-5-hydroxytryptamides (named C-5HT and C-5HT). The antinociceptive activities were evaluated using well-known models of thermal-induced (reaction to a heated plate, the hot plate model) or chemical-induced (licking response to paw injection of formalin, capsaicin, or glutamate) nociception. The mechanism of action for C-5HT and C-5HT was evaluated using naloxone (opioid receptor antagonist, 1 mg/kg), atropine (muscarinic receptor antagonist, 1 mg/kg), AM251 (cannabinoid CB1 receptor antagonist, 1 mg/kg), or ondansetron (5-HT3 serotoninergic receptor antagonist, 0.

Regulating and Cultural Ecosystem Services of Urban Green Infrastructure in the Nordic Countries: A Systematic Review.

In the Nordic countries (Denmark, Finland, Iceland, Norway and Sweden), the Urban Green Infrastructure (UGI) has been traditionally targeted at reducing flood risk. However, other Ecosystem Services (ES) became increasingly relevant in response to the challenges of urbanization and climate change. In total, 90 scientific articles addressing ES considered crucial contributions to the quality of life in cities are reviewed.

Peripherally inserted central catheter versus central venous catheter for intravenous access: A protocol for systematic review and meta-analysis.

Background: Since the first description of the central venous catheter (CVC) in 1952, it has been used for the rapid administration of drugs, chemotherapy, as a route for nutritional support, blood components, monitoring patients, or combinations of these. When CVC is used in the traditional routes (eg, subclavian, jugular, and femoral veins), the complication rates range up to 15% and are mainly due to mechanical dysfunction, infection, and thrombosis. The peripherally inserted central catheter (PICC) is an alternative option for CVC access.

Spontaneous carotid dissection.

Carotid dissection is a rare occurrence but it is the main cause of stroke in individuals aged less than 45 years, and can be the etiology in up to 25% of strokes in young adults. We report a case with classic image of ying yang on vascular ultrasound, which was treated according to the best available medical evidence, yielding a favorable outcome.

How Does the Amount and Composition of PM Deposited on Platanus acerifolia Leaves Change Across Different Cities in Europe?

Particulate matter (PM) deposited on Platanus acerifolia tree leaves has been sampled in the urban areas of 28 European cities, over 20 countries, with the aim of testing leaf deposited particles as indicator of atmospheric PM concentration and composition. Leaves have been collected close to streets characterized by heavy traffic and within urban parks. Leaf surface density, dimensions, and elemental composition of leaf deposited particles have been compared with leaf magnetic content, and discussed in connection with air quality data.
