Oxygen is commonly administered in hospitals, with poor adherence to treatment recommendations.We conducted a multicentre randomised controlled study in patients admitted to the emergency department requiring O2 ≥3 L·min(-1) Patients were randomised to automated closed-loop or manual O2 titration during 3 h. Patients were stratified according to arterial carbon dioxide tension (PaCO2 ) (hypoxaemic PaCO2 ≤45 mmHg; or hypercapnic PaCO2 >45-≤55 mmHg) and study centre. Arterial oxygen saturation measured by pulse oximetry (SpO2 ) goals were 92-96% for hypoxaemic, or 88-92% for hypercapnic patients...

BACKGROUND: Zika disease has transformed into a serious global health problem due to the rapid spread of the arbovirus and alarming severity including congenital complications, microcephaly and Guillain-Barré syndrome. Zika virus (ZIKV) is primarily transmitted to humans through the bite of an infective mosquito, with Aedes aegypti being the main vector. METHODS: We successfully developed a ZIKV experimental transmission model by single infectious Ae. aegypti bite to a laboratory mouse using circulating Brazilian strains of both arbovirus and vector...

The efficient transport of cargoes within axons and dendrites is critical for neuronal function. While we have a basic understanding of axonal transport, much less is known about transport in dendrites. We employed an optogenetic approach to recruit motor proteins to cargo in real time within axons or dendrites in hippocampal neurons. Kinesin-1, a robust axonal motor, moves cargo less efficiently in dendrites. In contrast, cytoplasmic dynein efficiently navigates both axons and dendrites; in both compartments, dynamic microtubule plus-ends enhance dynein-dependent transport...

In recent years, safer and more reliable biometric methods have been developed. Apart from the need for enhanced security, the media and entertainment sectors have also been applying biometrics in the emerging market of user-adaptable objects/systems to make these systems more user-friendly. However, the complexity of some state-of-the-art biometric systems (e.g., iris recognition) or their high false rejection rate (e.g., fingerprint recognition) is neither compatible with the simple hardware architecture required by reduced-size devices nor the new trend of implementing smart objects within the dynamic market of the Internet of Things (IoT)...

Solar radiation is considered the primary route for disinfection of pathogenic bacteria in maturation ponds. There is scarce information on depth profiling and attenuation of photosynthetically active radiation (PAR), UV-A and UV-B in shallow maturation ponds operating in tropical climates. Measurements of solar irradiance of the three wavelength ranges, together with turbidity, have been acquired from different depths for over 1 year in a shallow maturation pond (44 cm of depth) operating in Brazil. UV-A and UV-B were still detected at 10 cm from the surface, but from 15 cm both were undetectable...

The AKI in intensive care has been widely treated by international and national guidelines. The treatment of AKI in patients not requiring admission in Intensive Care Unit, but often hospitalized in Nephrology Unit, it is showed of less relevance. For over 5 years we have used for the treatment of AKI of patients admitted in Nephrology Unit an intermittent slow technique, implemented in approximately 600 patients with AKI for a total of about 3000 treatments. In this study we report the clinical results obtained in 100 consecutive patients referred to our Nephrology Unit from 1st January 2014...

Rutin is a glycosylated flavonoid present in many fruits and plants that has been demonstrated to have anti-inflammatory and antioxidant properties. However, little is known about the mechanisms underlying microglial activation and its effects on the regulation of cytokines and chemokines associated with inflammatory responses in the central nervous system. In this study we examined the effect of rutin on resting or lipopolysaccharide (LPS)-stimulated microglia and characterized their modulation to an activated M1 phenotype or an alternatively activated M2 phenotype...

BACKGROUND AND STUDY AIMS:  Performing a percutaneous endoscopic gastrostomy (PEG) in head and neck cancer (HNC) patients can be challenging because of the presence of trismus, pharyngeal obstruction by tumor, and pharyngoesophageal strictures or fistula. Pharyngocutaneous fistula (PCF) is a major postoperative concern in patients submitted to total laryngectomy (TL). In the medical literature to date, the cervical fistula has been used as an access to PEG in only four reports. The aim of this study was to evaluate the safety of cervical fistula for insertion of a PEG tube...
