5, 0.9, 1.5 and 3.0 mm/s and was found to be 7.8, 7.3, 6.6 and 5.5 mm, respectively. When the burr rotational speed increased from 3,000 to 60,000 rpm, the high-risk zone for thermal necrosis increased from 4.5 to 8.1 mm. We concluded that both the friction energy and the bone temperature increased in proportion with the burr rotational speed. Reducing burr rotational speeds and/or increasing feed rates may decrease the rise in bone temperature, thus decreasing the potential for thermal necrosis near the burring site. Our model can be used to select the optimal surgery parameters to minimise the risk of thermal necrosis due to bone burring and to assist in the design of optimal orthopaedic drill handpieces.Emotional human-computer interaction (HCI) has become an important research area in the fields of artificial intelligence and cognitive science, owing to the requirement for active emotion perception. To enhance the performance of electroencephalography (EEG)-based emotional HCI, this paper proposes an improved common spatial pattern combined with a channel-selection strategy (ICSPCS) for EEG-based emotion recognition. Specifically, we first use a common spatial pattern algorithm to design a spatial domain filter according to three different emotions (positive, neutral, and negative). The traditional joint approximation diagonalization method using the criterion of the "highest score eigenvalue" may be unable to solve multiple classifications of emotion representation. Therefore, we design three different eigenvalue selection methods in terms of the positions of the eigenvalues with the highest scores. Finally, to make the installation easier and reduce the computational load, we also develop a channel-selection strategy based on the weight values that individually reflect the degrees of influence of all the channels on emotion recognition. Experiments are conducted on a self-collected dataset and on the MAHNOB-HCI dataset. The average recognition accuracies for the three emotion tasks are found to be 85.85% and 94.13% on the self-collected and MAHNOB-HCI datasets, respectively, thus proving the effectiveness of the proposed ICSPCS method for emotion recognition.Introduction Temporal arteritis is an uncommon disorder in young people. A 39-year-old woman with juvenile temporal arteritis is described and we performed a literature review of all cases of juvenile temporal arteritis described to date. Case presentation A 39-year-old woman presented with a subcutaneous temporal nodule in the right temple with no other associated symptoms or background and unremarkable physical examination. Ultrasonography of the nodule revealed an anechoic perivascular halo surrounding the temporal artery. The nodule was excised resulting in the patient's recovery. The results of the histopathological study showed features of juvenile temporal arteritis. Conclusions Juvenile temporal arteritis is a very uncommon disorder. Systemic manifestations should be ruled out by physical examination and complementary tests. Histopathology establishes the definitive diagnosis. Treatment is surgical excision and a follow-up should be conducted to rule out complications.Background Drugs for neurohormonal antagonism are usually denied to patients with cardiac amyloidosis (CA) because of safety concerns. Methods Patients diagnosed with CA at a tertiary referral centre from 2009 to 2019 were enrolled. In the absence of contraindications, beta-blockers, angiotensin converting enzyme inhibitors or angiotensin receptor blockers (ACEi/ARB), and mineralocorticoid receptor antagonists (MRA) were started or up-titrated. Results 99 patients were evaluated (72% men, age 80 years [72,83], 33% light-chain and 67% transthyretin amyloidosis); 56% were started on or underwent up-titration of a beta-blocker, 25% of ACEi/ARB, and 39% of MRA; beta-blockers were then prescribed to 87% of patients, ACEi/ARB to 75%, and MRA to 63%, with median bisoprolol, ramipril, valsartan, and spironolactone daily equivalent doses of 2.5 mg, 5 mg, 80 mg, and 25 mg, respectively. Patients starting or starting/up-titrating a beta-blocker did not show a higher frequency of hypotension, fatigue, syncope, symptomatic bradycardia, need for pacemaker implantation, or HF hospitalization. Lower stroke volume and cardiac output (CO) predicted HF hospitalization regardless of amyloidosis type; lower left ventricular ejection fraction predicted hypotension, and lower CO and diastolic blood pressure predicted syncope. Patients who had an ACEi/ARB or MRA being started or up-titrated did not experience more adverse events than other patients. Conclusions ACEi/ARB and MRA can be safely used in CA, provided that no contraindications are present, treatment is started at a low dose and slowly up-titrated, and patients are monitored quite closely. Beta-blocker therapy is less tolerated in patients with AL amyloidosis and/or worse haemodynamic function.Emergency department management of hypoxemia in the setting of COVID-19 is riddled with uncertainty. The lack of high-quality research has translated to an absence of clarity at the bedside. With disease spread outpacing treatment consensus, provider discretion has taken on a heightened role. Here, we report a case of dexmedetomidine use in the setting of worsening hypoxemia, whereby oxygenation improved and intubation was avoided. Well known pharmacologic properties of the drug, namely the lack of respiratory depression and its anti-delirium effects, as well as other possible physiologic effects, suggest potential benefit for patients being managed with a delayed intubation approach. If dexmedetomidine can improve compliance with non-invasive oxygen support (the current recommended first-line therapy) while promoting better oxygenation, it may also decrease the need for mechanical ventilation and thus improve mortality.Fibroblast growth factors 1 and 2 (FGF1 and FGF2) are mainly considered as ligands of surface receptors through which they regulate a broad spectrum of biological processes. They are secreted in non-canonical way and, unlike other growth factors, they are able to translocate from the endosome to the cell interior. These unique features, as well as the role of the intracellular pool of FGF1 and FGF2, are far from being fully understood. An increasing number of reports address this problem, focusing on the intracellular interactions of FGF1 and 2. Here, we summarize the current state of knowledge of the FGF1 and FGF2 binding partners inside the cell and the possible role of these interactions. Selleck Epacadostat The partner proteins are grouped according to their function, including proteins involved in secretion, cell signaling, nucleocytoplasmic transport, binding and processing of nucleic acids, ATP binding, and cytoskeleton assembly. An in-depth analysis of the network of these binding partners could indicate novel, non-classical functions of FGF1 and FGF2 and uncover an additional level of a fine control of the well-known FGF-regulated cellular processes.
