To evaluate relative cytotoxicity of antibiotics to normal canine joint tissues in vitro.

Experimental in vitro study.

Chondrocytes and synoviocytes (three dogs); cartilage explants (three dogs); six dogs total.

Chondrocytes and synoviocytes from normal femoropatellar joints of three dogs were plated on 24-well plates (50 000 cells/cm

, triplicate, 48 hours) and exposed to antibiotics (ampicillin sulbactam, vancomycin, cefazolin, ceftazidime, amikacin, enrofloxacin; 0.39-25 mg/mL, 24 hours). Viability was assessed by using trypan blue dye exclusion. Antibiotic concentrations at which 50% cell death occurred (half-maximal inhibitory concentration) were determined to rank antibiotics for relative cytotoxicity. Pitavastatin research buy Occurrence of caspase-3 expression after antibiotic exposure was assessed as an indication of apoptosis induction. Cartilage explants from three different dogs were minced and exposed to antibiotics (amikacin, ceftazidime, cefazolin, enrofloxacin; 5 mg/mL, 72 hours). Live/dead staining was perfos.

These results provide evidence to justify future in vitro work with osteoarthritic joint tissues and in vivo clinical trials to evaluate safety and efficacy of intra-articular antibiotics to treat dogs with septic arthritis.

Parkinson's disease (PD) disrupts motor performance by affecting the basal ganglia system. Pitavastatin research buy Yet, despite the critical position of the primary motor cortex in linking basal ganglia computations with motor performance, its contribution to motor disability in PD is largely unknown. The objective of this study was to characterize the role of the primary motor cortex in PD-related motor disability.

Two-photon calcium imaging and optogenetic stimulation of primary motor cortex neurons was done during performance of a dexterous reach-to-grasp motor task in control and 6-hydroxydopamine-induced PD mice.

Experimental PD disrupted performance of the reach-to-grasp motor task and especially initiation of the task, which was partially restored by optogenetic activation of the primary motor cortex. Pitavastatin research buy Two-photon calcium imaging during task performance revealed experimental-PD affected the primary motor cortex in a cell-type-specific manner. It suppressed activation of output layer 5 pyramidal tract neurons, with greaterork. © 2021 International Parkinson and Movement Disorder Society.

Experimental PD disrupts both external driving and intrinsic properties of the primary motor cortex. Motor disability in experimental PD results primarily from the inability to generate robust and stable output motor sequences in the parkinsonian primary motor cortex output layer 5 pyramidal tract subnetwork. © 2021 International Parkinson and Movement Disorder Society.Hypermethioninemia is characterized by high plasma concentrations of methionine (Met) and its metabolites, such as methionine sulfoxide (MetO), and neurological changes, such as cerebral edema and cognitive deficits. The aim of this study was to analyze the redox status and acetylcholinesterase (AChE) activity in the hippocampus, striatum, and cerebellum of young Wistar rats subjected to an acute hypermethioninemia protocol. The animals received, by subcutaneous injection, a single dose of Met (0.4 g/kg), MetO (0.1 g/kg), and Met + MetO, and 1 or 3 hr after administration, the animals were euthanatized for brain structure obtaining. In the hippocampus, an increase in lipid peroxidation and glutathione peroxidase (GPx) activity was observed at 1 hr in the MetO and Met + MetO groups, and a reduction in the superoxide dismutase activity was found in the Met + MetO group. link2 Met and/or MetO induced a decrease in the thiol content and GPx activity and enhanced the lipid peroxidation at 3 hr. In the striatum, a reduction in the thiol content and GPx activity, an increase in lipid peroxidation, and AChE activity were induced by Met and/or MetO at 1 or 3 hr. Additionally, in the cerebellum, an increase in the AChE in the MetO and Met + MetO groups 1 hr after administration was observed. These data help to better understand the pathophysiological mechanisms that underlie the neurological changes found in hypermethioninemia patients.

Behavioural disturbances such as agitation are common following traumatic brain injury and can interfere with treatments, cause self-harm and delay rehabilitation. As there is a lack of evidence on the optimal approach to manage agitation in recovering TBI patients, various pharmacological agents are used including antipsychotics, anticonvulsants and sedative agents. Among sedatives, the safety and efficacy of dexmedetomidine to control agitation in traumatic brain injury patients is not well documented.

To describe the safety, use and efficacy of dexmedetomidine for the management of agitation following traumatic brain injury in the intensive care unit.

Medical records of all patients admitted to the intensive care unit of the Hôpital Sacré-Coeur de Montréal for a traumatic brain injury who received dexmedetomidine for agitation between 1 January 2017 and 31 December 2017 were reviewed. link2 link2 Patients who received dexmedetomidine for indications other than agitation were excluded. Data on dexmedetomidine prexmedetomidine use was safe and associated with a reduction in agitation in traumatic brain injury patients in the 96 hours following its initiation.

Methamphetamine (meth) is a powerful, highly addictive stimulant that affects the central nervous system, and its side effects may result in severe self-mutilation. This report describes a case of a meth user with severe oral injury that demonstrates the necessity for prompt treatment when severe tongue biting occurs.

A 43-year-old meth-using man with severe tongue biting was left untreated for more than 24hours, resulting in extensive ischemic changes in the tongue and eventual extensive tissue necrosis. After debridement and deep suture repair in several layers, the wound healed. However, tongue dysfunction and a speech disorder remained because of tongue shortening.

Meth may induce or aggravate severe oral self-mutilation. Tongue biting with severe tissue damage may occur as oral self-mutilation in meth users; however, among self-mutilation behaviors, tongue biting is especially difficult to prevent. A withdrawal from meth and a behavioral approach may be necessary for fundamental prevention, but it is often difficult in high dependence users. When severe tongue biting occurs, prompt suture reconstruction must be performed before ischemic change occurs to prevent tissue necrosis.

For example, one prominent idea put forward by the High-Level Expert Group on Artificial Intelligence appointed by the European Commission is that artificial intelligence should be trustworthy. In this essay, we explore the notion of trust and argue that both proponents and critics of trustworthy AI have flawed pictures of the nature of trust. We develop an approach to understanding trust in AI that does not conceive of trust merely as an accelerator for societal acceptance of AI technologies. Instead, we argue, trust is granted through leaps of faith. For this reason, trust remains precarious, fragile, and resistant to promotion through formulaic approaches. We also highlight the significance of distrust in societal deliberation, as it is relevant to trust in various and intricate ways. Among the fruitful aspects of distrust is that it enables individuals to forgo technology if desired, to constrain its power, and to exercise meaningful human control.Chronic musculoskeletal (MSK) pain is disabling to individuals and burdensome to society. A relationship between telomere length and resilience was reported in individuals with consideration for chronic pain intensity. While chronic pain associates with brain changes, little is known regarding the neurobiological interface of resilience. link3 link3 In a group of individuals with chronic MSK pain, we examined the relationships between a previously investigated resilience index, clinical pain and functioning measures, and pain-related brain structures, with consideration for sex and ethnicity/race. A cross-sectional analysis of 166 non-Hispanic Black and non-Hispanic White adults, 45-85 years of age with pain ≥ 1 body site (s) over the past 3 months was completed. Measures of clinical pain and functioning, biobehavioral and psychosocial resilience, and structural MRI were completed. Our findings indicate higher levels of resilience associate with lower levels of clinical pain and functional limitations. Significant associations between resilience, ethnicity/race, and/or sex, and pain-related brain gray matter structure were demonstrated in the right amygdaloid complex, bilateral thalamus, and postcentral gyrus. Our findings provide compelling evidence that in order to decipher the neurobiological code of chronic pain and related protective factors, it will be important to improve how chronic pain is phenotyped; to include an equal representation of females in studies including analyses stratifying by sex, and to consider other sociodemographic factors.

Patients with advanced cancer are faced with a wide variety of challenges and difficult treatment decisions made while in a vulnerable life-threatening situation, including decisions about clinical trial participation. Internationally, there is a great focus on shared decision-making as a way to help patients and healthcare professionals to make informed decisions together; nevertheless, research focusing on patient experiences shows that information about clinical trials is insufficient in supporting patients to make trial decisions in the context of their course of disease and managing life with advanced cancer.

To explore where and how decisions about participation in oncology clinical trials are made and the role of the patients and healthcare professionals.

Participant observation was used as a qualitative research method to gain knowledge about decision-making in different clinical situations. Data were analysed using thematic analysis.

Four themes were developed (a) preformed decisions, (b) disal issues in the clinical encounter may improve the quality of the decisions and increase shared decision-making.

The objectives were to measure the proportion of aspirated material used to make direct slides for rapid onsite evaluation (ROSE) at endobronchial (EBUS) and endoscopic ultrasound (EUS) in suspected thoracic malignancy; and to correlate pass weights with ROSE category and needle size.

All EBUS and EUS cases for possible thoracic malignancy October 2018-May 2019 were included. All material from each pass was expelled into a Petri dish. One drop of material was placed on each of two slides; one used for ROSE, the other fixed and remaining material processed to cell block. Dish and slides were weighed before and after this procedure on a sensitive balance and weight of aspirate and slide material calculated. link3 When ROSE identified malignancy, slide production ceased but target sampling for ancillary studies continued.

ROSE accuracy was 96.8%. Mean percentage by target of aspirated material used to make direct slides for ROSE was 1.9% in malignant cases and 3.6% in non-malignant cases (P=.027 for difference).
