Cattle with short fasting duration had higher carcass weights and water consumption than those under long fasting duration. Haematocrit, globulin, total protein, and lactate dehydrogenase at the time of slaughter increased with fasting duration. There was no effect of the duration of fasting on blood ions, meat quality traits, urine pH, liver weight and volume, and skin dry matter. A reduction in the fasting duration returned to farmers and abattoirs 1.2% additional kilograms of carcass, suggesting an improvement in animal welfare according to a better hydration level of cattle at the time of slaughter.
The ‘chapeau de gendarme’ (CDG) sign, characterised by a symmetric down-turned mouth, has been considered as a semiological hallmark of focal epileptic seizures with cingulate or insular involvement. We report three cases in which the CDG sign featured in habitual seizures.
The epileptogenic zones of these three patients were localized in the lateral prefrontal cortex by video-stereoelectroencephalography monitoring. PF-562271 price A sulcal resection has led to a seizure-free outcome in each patient.
Ictal stereoelectroencephalography demonstrated that ictal discharges arising from the lateral prefrontal cortices were immediately followed by low-voltage fast activity, concomitantly involving the anterior insulo-cingulate cortices, and preceding the onset of the CDG signs. Limited sulcal resection and seizure freedom after surgery confirmed the restricted distributions of the epileptogenic zones in the lateral prefrontal cortex.
Our observations led us to speculate that the epileptic discharges could enter the emotional insulo-cingulate cortical system through the prefrontal-cingulate inhibitory projections (feedforward pattern) -arising from the supragranular layers of the lateral prefrontal cortex-and proceed to the deeper layers of the anterior-middle cingulate cortex, trigger the co-occurrence of gamma bands, and evoke a set of exaggerated behaviours, which is often accompanied by the unique facial sign.

Here, we present a case of steroid-responsive MOG-antibody associated encephalitis, characterized by cognitive decline, headaches, fever, unilateral FLAIR-hyperintensities, and leptomeningeal enhancement, that occurred in the setting of recent COVID-19 infection.
Primary progressive multiple sclerosis (PPMS) has long been defined by progressive disability accrual in the absence of initial relapses. However, its underlying neurodegenerative process seems to be accompanied by central nervous system inflammation. A new classification defined multiple sclerosis courses according to clinical/radiological activity and progression. We provide further insight into PPMS activity according to this classification and other daily living aspects.
This was a multicentre, prospective, cohort study including 55 adult patients with PPMS according to 2010 McDonald criteria, within ten years from neurologic symptom onset and not receiving disease-modifying therapies during the past six months, who were followed up for 12 months. The primary study endpoint was the percentage of patients with active disease based on clinical relapses and/or magnetic resonance activity. Disability progression, cognitive function, physical/psychological impact, depression symptoms, stigma and employmentsease activity over one year, with disability progression in approximately one-third but without worsening of cognitive function, disease impact, depression, stigma or employment outcomes.
The COVID-19 pandemic significantly altered treatment delivery for opioid treatment programs (OTPs) dispensing medications for opioid use disorder (MOUD). We aimed to identify patterns of substance use among MOUD patients and examine whether COVID-19-related impacts on access to healthcare varied across subgroups.
This analysis was embedded within a type 3 hybrid trial that enrolled patients across eight OTPs at the start of the pandemic. Enrolled patients reported on past-30 day use of multiple substances during their baseline assessment. Participants re-contacted in May-July 2020 completed a survey about COVID-19-related impacts on various life domains. Using latent class analysis we identified patient subgroups, and then examined group differences on a set of negative and positive COVID-19 impacts related to healthcare access.
Of the 188 trial participants, 135 (72 %) completed the survey. Latent class analysis identified three MOUD patient subgroups minimal use (class probability 0.25); opioid use (class probability 0.34); and polysubstance use (class probability 0.41). Compared to the minimal use group, the polysubstance use group reported increased substance use and difficulty accessing sterile needles, naloxone, and preferred substance. The opioid use group reported increased substance use and difficulty accessing their preferred substance. There were no significant group differences related to accessing routine or specialized healthcare or medication; or paying attention to their health.
During COVID-19, many MOUD patients reported challenges accessing care, particularly harm reduction services for patients with polysubstance use. Additional efforts, like providing wraparound support, may be necessary to serve the needs of MOUD patients.

MicroRNAs (miRNAs) are “master post-transcriptional regulators” of gene expression. Here we investigate miRNAs involved in the incentive motivation for cocaine elicited by exposure to cocaine-associated cues.
We conducted NanoString nCounter analyses of microRNA expression in the nucleus accumbens shell of male rats that had been tested for cue reactivity in a previous study. These rats had been trained to self-administer cocaine while living in isolate housing, then during a subsequent 21-day forced abstinence period they either stayed under isolate housing or switched to environmental enrichment (EE), as this EE intervention is known to decrease cocaine seeking. This allowed us to create groups of “high” and “low” cocaine seekers using a median split of cocaine-seeking behavior.
Differential expression analysis across high- and low-seekers identified 33 microRNAs that were differentially expressed in the nucleus accumbens shell. Predicted mRNA targets of these microRNAs are implicated in synaptic plasticity, neuronal signaling, and neuroinflammation signaling, and many are known addiction-related genes.
