A consensus is yet to be reached regarding the exact prevalence of epileptic seizures or epilepsy in multiple sclerosis (MS). In addition, the underlying pathophysiological basis of the reciprocal interaction among neuroinflammation, demyelination, and epilepsy remains unclear. Therefore, a better understanding of cellular and network mechanisms linking these pathologies is needed. Cuprizone-induced general demyelination in rodents is a valuable model for studying MS pathologies. Here, we studied the relationship among epileptic activity, loss of myelin, and pro-inflammatory cytokines by inducing acute, generalized demyelination in a genetic mouse model of human absence epilepsy, C3H/HeJ mice. Both cellular and network mechanisms were studied using in vivo and in vitro electrophysiological techniques. We found that acute, generalized demyelination in C3H/HeJ mice resulted in a lower number of spike-wave discharges, increased cortical theta oscillations, and reduction of slow rhythmic intrathalamic burst activity. In addition, generalized demyelination resulted in a significant reduction in the amplitude of the hyperpolarization-activated inward current (Ih) in thalamic relay cells, which was accompanied by lower surface expression of hyperpolarization-activated, cyclic nucleotide-gated channels, and the phosphorylated form of TRIP8b (pS237-TRIP8b). We suggest that demyelination-related changes in thalamic Ih may be one of the factors defining the prevalence of seizures in MS.
Salmonella enterica serotype 4,[5],12i- (STM) has become an increasing problem for food safety and has been often detected in swine products. Weanling pigs were exposed to STM-contaminated feed, water, or air to determine possible STM transmission routes. A control group of pigs was included. STM was monitored daily in feces and rectal and nasal swabs. STM colonization was most prevalent in tissues from tonsil, lower intestine, and mesenteric lymph nodes. No differences in lesion severity were observed between inoculated and control pigs. Contaminated feed, water, and aerosolized particles caused infection in weaned pigs; however, no STM colonization was observed in skeletal muscle destined for human consumption. Based on the results from this study, STM contamination in pork products most likely results from cross-contamination of meat by digesta or lymph node tissue during processing.
A set of distributed cognitive control networks are known to contribute to diverse cognitive demands, yet it is unclear how these networks gain this domain-general capacity. We hypothesized that this capacity is largely due to the particular organization of the human brain's intrinsic network architecture. Specifically, we tested the possibility that each brain region's domain generality is reflected in its level of global (hub-like) intrinsic connectivity as well as its particular global connectivity pattern ("connectivity fingerprint"). Consistent with prior work, we found that cognitive control networks exhibited domain generality as they represented diverse task context information covering sensory, motor response, and logic rule domains. https://www.selleckchem.com/products/genipin.html Supporting our hypothesis, we found that the level of global intrinsic connectivity (estimated with resting-state functional magnetic resonance imaging [fMRI]) was correlated with domain generality during tasks. Further, using a novel information fingerprint mapping approach, we found that each cognitive control region's unique rule response profile("information fingerprint") could be predicted based on its unique intrinsic connectivity fingerprint and the information content in regions outside cognitive control networks. Together, these results suggest that the human brain's intrinsic network architecture supports its ability to represent diverse cognitive task information largely via the location of multiple-demand regions within the brain's global network organization.Selective attention is thought to involve target enhancement and distractor inhibition processes. Here, we recorded simultaneous electroencephalographic (EEG) and functional near-infrared spectroscopy (fNIRS) data from human adults when they were pre-cued by the visual field of coming target, distractor, or both of them. From the EEG data, we found alpha power relatively decreased contralaterally to the to-be-attended target, as reflected by the positive-going alpha modulation index. Late alpha power relatively increased contralaterally to the to-be-suppressed distractor, as reflected by the negative-going alpha modulation index. From the fNIRS data, we found enhancements of hemodynamic activity over the contralateral hemisphere in response to both the target and the distractor anticipation but within nonoverlapping posterior brain regions. More importantly, we described the specific neurovascular modulation between alpha power and oxygenated hemoglobin signal, which showed a positive coupling effect during target anticipation and a negative coupling effect during distractor anticipation. Such flexible neurovascular couplings between EEG oscillation and hemodynamic activity seem to play an essential role in the final behavioral outcomes. These results provide unique neurovascular evidence for the dissociation of the mechanisms of target enhancement and distractor inhibition. Individual behavioral differences can be related to individual differences in neurovascular coupling.
Vamorolone is a synthetic steroidal drug with potent anti-inflammatory properties. Initial open-label, multiple ascending dose-finding studies of vamorolone among boys with Duchenne muscular dystrophy (DMD) found significant motor function improvement after 6 months treatment in higher-dose (ie, ≥2.0 mg/kg/d) groups.

To investigate outcomes after 30 months of open-label vamorolone treatment.

This nonrandomized controlled trial was conducted by the Cooperative International Neuromuscular Research Group at 11 US and non-US study sites. Participants were 46 boys ages 4.5 to 7.5 years with DMD who completed the 6-month dose-finding study. Data were analyzed from July 2020 through November 2021.

Participants were enrolled in a 24-month, long-term extension (LTE) study with vamorolone dose escalated to 2.0 or 6.0 mg/kg/d.

Change in time-to-stand (TTSTAND) velocity from dose-finding baseline to end of LTE study was the primary outcome. Efficacy assessments included timed function tests, 6-minute walk test,ared with growth deceleration associated with glucocorticoid treatment, suggesting that vamorolone may be an attractive candidate for treatment of DMD.

Although the public is aware that cancer is associated with excess mortality and adverse outcomes, the clinical consequences of chronic kidney disease (CKD) are not well understood.

To compare the clinical consequences of incident severe CKD and the first diagnosis with a malignant tumor, focusing on the 10 leading causes of cancer in men and women residing in Canada.

This population-based cohort study enrolled individuals aged 19 years and older with severe CKD or certain types of cancer between 2004 and 2015 in Alberta, Canada. Data were analyzed in November 2021.

Individuals were categorized as having severe CKD (based on estimated glomerular filtration rate <30 mL/min/1.73 m2 or nephrotic albuminuria without dialysis or kidney transplantation) or nonmetastatic or metastatic cancer (defined by a diagnosis of lung, breast, colorectal, prostate, bladder, thyroid, kidney or renal pelvis, uterus, pancreas, or oral cancer).

All-cause mortality, number of hospitalizations, total number of hospital dsimilar for CKD and nonmetastatic cancer. These data highlight the importance of CKD as a public health problem.
Oncology drug prices are a determinant of health disparities in the US and worldwide. Several new therapeutic agents for non-small cell lung cancer (NSCLC) have become available on the US market over the past decade. Although increased competition typically produces lower prices, competition among brand-name oncology drugs has not resulted in lower prices.

To assess price changes in class-specific brand-name medications used to treat metastatic NSCLC in the US from 2015 to 2020.

This cross-sectional study, conducted from August 13, 2015, to August 13, 2020, used data from the Micromedex Red Book and Medi-Span Price Rx databases. The study sample was limited to 17 brand-name medications used to treat metastatic NSCLC that were available for purchase before January 1, 2019.

The main outcomes were trends over time in average wholesale prices and wholesale acquisition cost unit prices and the correlation in price among the multiple brand-name medications within each therapeutic class (immune checkpoint in inhibitors, 2.56% (range, 2.38%-5.26%) for epidermal growth factor receptor inhibitors, 2.46% (range, 1.75%-4.66%) for anaplastic lymphoma kinase and ROS1 inhibitors, and 3.06% (range, 0%-3.06%) for BRAF and MEK inhibitors.

In this cross-sectional study, prices of brand-name medications for treatment of NSCLC increased in the US from 2015 to 2020 without evidence of price competition, raising concern about the affordability of promising oncology drugs. These findings suggest that drug pricing reform is needed.

Emergency departments (EDs) are increasingly initiating treatment for patients with untreated opioid use disorder (OUD) and linking them to ongoing addiction care. To our knowledge, patient perspectives related to their ED visit have not been characterized and may influence their access to and interest in OUD treatment.

To assess the experiences and perspectives regarding ED-initiated health care and OUD treatment among US patients with untreated OUD seen in the ED.

This qualitative study, conducted as part of 2 studies (Project ED Health and ED-CONNECT), included individuals with untreated OUD who were recruited during an ED visit in EDs at 4 urban academic centers, 1 public safety net hospital, and 1 rural critical access hospital in 5 disparate US regions. Focus groups were conducted between June 2018 and January 2019.

Data collection and thematic analysis were grounded in the Promoting Action on Research Implementation in Health Services (PARIHS) implementation science framework with evidence (perstrategies to address stigma, acknowledge and treat pain, and provide ED staff training should be implemented to improve ED care for patients with OUD and enhance access to life-saving treatment.
In this qualitative study, patients with OUD reported feeling stigmatized and minimized when accessing care in the ED and identified several opportunities to improve care. The findings suggest that strategies to address stigma, acknowledge and treat pain, and provide ED staff training should be implemented to improve ED care for patients with OUD and enhance access to life-saving treatment.
