The core material content, slow-release performance, and flame retardancy of SFRM were measured using a UV-1800 spectrophotometer and Hartmann tubes, and the compressive and repair properties of SFRM were evaluated by uniaxial compression tests. The results demonstrate that SFRM has satisfactory slow-release and flame-retardancy properties, the LC is 67%, and the first-order kinetic model shows the best fit and conforms to the non-Fickian diffusion mechanism. The SFRM repair rate can reach approximately 61%. This is of substantial significance to the field of self-repairing cement-based materials.The rapid development of wearable electronics and smart textiles has dramatically motivated the generation of flexible textile-based supercapacitors (SCs). However, the rapid evaporation of water moisture in gel electrolyte substantially limits the working durability and performance enhancements of the flexible devices. Therefore, a high-performance multifunctional textile-based SC with long-term durability is highly desired. Herein, a poly(vinyl alcohol) (PVA)/polyacrylamide (PAM) composite gel electrolyte was developed to fabricate multifunctional device with water-retaining and water-proofing properties based on multidimensional hierarchical fabric. And the assembled SC based on composite gel exhibited a superior water-retaining property and long-term working durability (93.29% retention rate after operation for 15 days), whereas the performance of SC based on pure PVA gel declined sharply and only 43.2% capacitance remained. In addition, the assembled SC exhibited enhanced specific capacitance of 707.9 mF/cm2 and high energy density of 62.92 μWh/cm2 and maintained a good stability of 80.8% even after 10 000 cyclic tests. After water repellency treatment, the integrated device immersed in water could still work normally. What's more, the assembled devices could be charged by a portable hand generator, which could be potentially applied for field rescue and military applications. We foresee that this strategy would be a potential route to prepare high-performance multifunctional textile-based SCs for wearable electronic systems and smart textile applications.As an excellent electrocatalyst, platinum (Pt) is often deposited as a thin layer on a nanoscale substrate to achieve high utilization efficiency. However, the practical application of the as-designed catalysts has been substantially restricted by the poor durability arising from the leaching of cores. Herein, by employing amorphous palladium phosphide (a-Pd-P) as substrates, we develop a class of leaching-free, ultrastable core-shell Pt catalysts with well-controlled shell thicknesses and surface structures for fuel cell electrocatalysis. When a submonolayer of Pt is deposited on the 6 nm nanocubes, the resulting Pd@a-Pd-P@PtSML core-shell catalyst can deliver a mass activity as high as 4.08 A/mgPt and 1.37 A/mgPd+Pt toward the oxygen reduction reaction at 0.9 V vs the reversible hydrogen electrode and undergoes 50 000 potential cycles with only ∼9% activity loss and negligible structural deformation. As elucidated by the DFT calculations, the superior durability of the catalysts originates from the high corrosion resistance of the disordered a-Pd-P substrates and the strong interfacial Pt-P interactions between the Pt shell and amorphous Pd-P layer.Among the germanium-based compounds, GeTe is a promising anode candidate that exhibits high theoretical capacity (856 mAh g-1 vs Li+/Li and 401 mAh g-1 vs Na+/Na) and low volume expansion during an ion intercalation/deintercalation process. Nevertheless, achieving good dispersion of metal-like GeTe in anode materials remains a significant challenge. SF1670 Herein, hybrid GeTe/graphene (GeTe/G) is proposed as a highly efficient anode for LiBs and SiBs by facile ball milling. Pulverized GeTe is effectively anchored on peeled graphene sheets that can accelerate Li+ transport in electrodes as predicted by theoretical calculations and thus result in improved overall electrochemical performance. For instance, GeTe/G possesses a high reversible capacity of 478 mAh g-1 under 0.1 A g-1 in the 300th cycle. Moreover, by further cross-linking the GeTe/G using carbon nanotube (CNT) and carbon nanofiber pyrolysis from cotton cellulose, the as-prepared three-dimensional (3D) flexible anode possesses macropores that acted as positive channels favorably for ion transport. Remarkably, the as-prepared flexible 3D GeTe/G/CNT electrode with a thickness of 1050 μm exhibits a high reversible capacity of 451.4 mAh g-1 (4.38 mAh cm-2) vs Li+/Li and 372.5 mAh g-1 (2.08 mAh cm-2) vs Na+/Na, respectively, in the second cycle under 0.1 A g-1. These results shed some light on the direct application of 3D flexible carbon sponge electrodes in high-performance LiBs/SiBs.

Neurosarcoidosis is a rare form of sarcoidosis that affects the nervous system. The aim of the study was to survey clinical manifestations, findings from assessments and treatment strategies for patients with neurosarcoidosis.

The study performed a retrospective assessment of 17patients with definitive, probable and possible neurosarcoidosis diagnosed in the period 2008-2019 at the Department of Neurology, Haukeland University Hospital.

The average prevalence of definitive, probable or possible neurosarcoidosis in Norway's Vestland county was 2.7per 100 000 inhabitants in the period in question. Onset took the form of central nervous affection (8 of 17), hydrocephalus (5 of 17) and cranial neuropathy (5 of 17). Sarcoidosis-like findings were made in 14 of 17patients by means of contrast-enhanced magnetic resonance tomography (MRT) of the central nervous system, in 7 of 8patients by positron emission tomography (PET), and in 12 of 16patients by computed tomography (CT) of the thorax. There were cerebrosp to pinpoint biopsy sites. Corticosteroid therapy, and in some cases other immunotherapy, elicits a good response.

Tonsillectomy and tonsillotomy are common surgical procedures, especially among children and adolescents. Post-operative bleeding is a potentially alarming and dangerous complication. We wished to identify the prevalence of postoperative bleeding and associated risk factors in Ålesund hospital.

The study is based on a retrospective review of the records of all patients who underwent tonsil surgery at Ålesund hospital in the five-year period from 2015-2019.

Of 1394patients who underwent tonsil surgery, tonsillectomy was performed in 1285patients and tonsillotomy in 109patients. Thirty patients (2.2%) had primary haemorrhage (< 24 hours). Twenty patients (1.4%) were hospitalised due to secondary haemorrhage (> 24 hours), after an average of 5.4 days. Five patients (0.4%) were reoperated due to postoperative bleeding. No postoperative bleeding was recorded after tonsillotomy. Increased risk of late postoperative bleeding was found for patients aged 16 years and over, and patients with primary haemorrhage.

The proportion of cases of postoperative bleeding was low compared to international studies. Our figures are likely representative for other otorhinolaryngology departments in Norway, and may provide useful information to clinicians and patients prior to tonsil surgery.

The aetiology of transient monocular vision loss is not necessarily thromboembolic, and careful history-taking is crucial in making the correct diagnosis.

A previously healthy woman in her thirties was referred to our outpatient stroke clinic on suspicion of recurring amaurosis fugax in her right eye. The ophthalmic and neurologic examinations were normal. A review of the medical history revealed that her symptoms occurred in connection with using her smartphone in bed, typically while lying on her left side with the left eye covered by the pillow. When standing up from the bed again with the lights turned off in the bedroom, she noticed vision loss in her right eye.

We concluded that the patient had experienced transient smartphone blindness. link2 This phenomenon can occur when monocularly using a smartphone under scotopic lighting conditions; only the occluded eye adapts to darkness, and the other eye is perceived to be blind if looking away from the bright smartphone screen.

Errors in the use and administration of medicinal drugs are not uncommon. There is little up-to-date information available on medication errors in Norwegian hospitals.

It is compulsory to report all adverse events internally at St Olav's Hospital via an electronic form. For the three-year period 2015-2017 we have reviewed all medication errors in the database where the reports are stored and compared them with figures from a similar study conducted in the period 2002-2006.

Altogether 1604medication errors were registered, distributed among 1587 reports. Dosing errors were most common (n=1070; 67%), followed by administration of another drug than prescribed (n=175; 11%). Most errors were of an insignificant or low degree of severity. There was a preponderance of reporting among the youngest and the oldest patients. 79% of the errors were reported by nurses. Inattention/forgetfulness (15%), stress/high workload (12%), sloppy documentation in drug charts (10%) and erroneous/unclear prescribing (10%) were reported as the most frequent causes.

The number of reports of medication errors is increasing, but the extent of underreporting is uncertain. The types of errors and their distribution are similar to previous studies. The underlying causes are also well known; the challenge is to prevent these situations from arising.

I motsetning til i dag var busetjinga på landsbygda organisert i tette fellestun for fleire bondefamiliar fram til om lag den første verdskrigen, særleg på Vestlandet. I desse tuna kunne det vere 50-60 bygningar, med bustadhus, fjøs, uthus, folk og fe om kvarandre.

Dei er utført ein analyse av dei såkalla medisinalmeldingane dei statleg oppnemnde distriktslækjarane sendte til styresmaktene på 1800-talet, med mål om at desse kan seie noko om korleis distriktslækjarane stilte seg til dei hygieniske tilhøva i dei tette fellestuna.

Medisinalmeldingane viser at det gjentekne gonger vart peika på at smittefaren var stor og at fellestuna var ei lite tenleg busetnadsform sett frå distriktslækjarane sin synsstad. Med heimel i lov av 1857 vart også den statlege utskiftingsetaten etablert to år seinare. Målet var å få ei meir tenleg og moderne organisering av gardane. link3 Dette førte til at dei aller fleste av dei gamle fellestuna vart splitta opp og at ein fekk meir spreidde og sunnare busetnadsformer. Artikkelen viser likevel at det var dei agronomiske vinningane som primært stod i fokus hjå lovgjevarane og reformatorane, og ikkje ei betring av dei hygieniske tilhøva.
