The robot-assisted platform offers a versatile and affordable option for reproducible sample processing for a wide range of protein profiling applications.Neuromuscular diseases result in muscle weakness, disability, and, in many instances, death. Preclinical models form the bedrock of research into these disorders, and the development of in vivo and potentially translational biomarkers for the accurate identification of disease is crucial. Spontaneous Raman spectroscopy can provide a rapid, label-free, and highly specific molecular fingerprint of tissue, making it an attractive potential biomarker. In this study, we have developed and tested an in vivo intramuscular fiber optic Raman technique in two mouse models of devastating human neuromuscular diseases, amyotrophic lateral sclerosis, and Duchenne muscular dystrophy (SOD1G93A and mdx, respectively). The method identified diseased and healthy muscle with high classification accuracies (area under the receiver operating characteristic curves (AUROC) 0.76-0.92). In addition, changes in diseased muscle over time were also identified (AUROCs 0.89-0.97). Key spectral changes related to proteins and the loss of α-helix protein structure. Importantly, in vivo recording did not cause functional motor impairment and only a limited, resolving tissue injury was seen on high-resolution magnetic resonance imaging. Lastly, we demonstrate that ex vivo muscle from human patients with these conditions produced similar spectra to those observed in mice. We conclude that spontaneous Raman spectroscopy of muscle shows promise as a translational research tool.Pt-based catalysts are commercial electrocatalysts for the hydrogen evolution reaction (HER), but their shortcomings of expensive and imperfect efficiency hinder their large-scale application. Here, we report an Ir-based HER catalyst supported by N-doped carbon nanosheets (Ir-NCNSs). The NCNSs, with a high surface area and unique atomic composition, enable Ir nanoparticles (NPs) to disperse at 2-3 nm and strongly coordinate to the Ir through Ir-N bonds, which exposes many active sites and strengthens their durability. The catalyst displays a low overpotential and a small Tafel slope of 46.3 mV at 10 mA cm-2 and 52 mV dec-1 in 0.5 M H2SO4, respectively. When used in 1.0 M KOH, Ir-NCNSs also show excellent electrocatalytic activity with a low overpotential of 125 mV at 10 mA cm-2. The calculated results further suggest that Ir NPs and NCNSs have excellent selectivity for strong metal-support interactions, corresponding to a significant and stable HER characteristic.

Testing for airway microbes has increased during the current COVID-19pandemic. This case report demonstrates that testing can lead to complications.

A man in his seventies was transferred to our hospital for coronary angiography. On admission he underwent testing with nasopharyngeal swab for COVID-19. He started bleeding profusely from the nostril insertion site. The haemorrhage was controlled by bilateral anterior and posterior balloon tamponade, the coronary angiography was postponed, he was given a transfusion of packed red blood cells and had to spend a total of nine days in hospital.

The World Health Organization recommends screening of all patients for COVID-19 upon admission to hospital. The risk of every procedure must be carefully considered in relation to the benefits, especially when large numbers of patients are affected. For our patient, the likelihood of COVID-19 infection was low, and the risk of complications was high.

Poisonings by substances of abuse are potentially dangerous and indicate risky substance use behaviour. To be prepared to handle patients with poisonings by substances of abuse, we need updated knowledge about the kinds of substances we can be expected to encounter. Most substance use-related poisonings in Oslo are treated at the OAEOC, and we describe the poisonings observed there in the period 2014-2018.

We included all patients treated for poisoning by substances of abuse at the OAEOC in the years 2014-18, with the exception of lone ethanol poisonings. For 2018, these were also included. The patients were identified retrospectively by a review of the patient registration lists in the clinic's electronic records system. The diagnosis of the substances involved was based on the clinical assessment made by the doctor responsible for treatment.

In the period 2014-18, altogether 8116 cases of poisoning by a substance of abuse were treated at OAEOC, lone ethanol poisonings not included. The most frequently occurring intoxicants were heroin (3237 cases), benzodiazepines (2196), amphetamine/methamphetamine (1827), cannabis (1081), gamma-hydroxybutyrate (GHB) (904), cocaine (569) and unspecified opioids (546). There was an increasing trend in number of cases per year for central stimulants, cannabis and GHB, and a decreasing one for benzodiazepines. The number of heroin poisonings fell until 2017, but rose again in 2018. In 2018 there were 4021poisonings by substances of abuse, of which 2022 were lone ethanol poisonings.

The number of poisonings increased for most substances in 2014-18, but fell for heroin and benzodiazepines.

The Scandinavian guidelines for initial management of minimal, mild and moderate head injuries in adults aim to identify patients at risk of developing intracranial haematoma, while also avoiding unnecessary computed tomography (CT) scans and hospital admissions. We examined compliance with the guidelines at the University Hospital of North Norway, Tromsø.

A search in the patient administration system identified 448patients with a diagnosis code for head injury. We excluded 298 who met one or more exclusion criteria, and included 150 with minimal, mild or moderate injuries in a retrospective study. Management was categorised as being either compliant or non-compliant with the guidelines. We defined non-compliance as overtesting (unnecessary CT scan and/or hospital admission) or undertesting (omission of necessary CT scan and/or hospital admission).

Management was in accordance with the guidelines for 96/150 (64%) patients. This proportion increased with the severity of the injury (minimal 4/12 (33%), mild 76/119 (64%) and moderate 16/19 (84%)).
