Biomarkers for future adaptive deep brain stimulation still need evaluation in clinical routine. Here, we aimed to assess stimulation-induced modulation of beta-band activity and clinical symptoms in a Parkinson's disease patient during chronic neuronal sensing using a novel implantable pulse generator.

Subthalamic activity was recorded OFF and ON medication during a stepwise increase of stimulation amplitude. Off-line fast fourier transfom -based analysis of beta-band activity was correlated with motor performance rated from blinded videos.

The stepwise increase of stimulation amplitude resulted in decreased beta oscillatory activity and improvement of bradykinesia. Doramapimod Mean low beta-band (13-20Hz) activity correlated significantly with bradykinesia (ρ= 0.662, p<0.01).

Motor improvement is reflected in reduced subthalamic beta-band activity in Parkinson's disease, supporting beta activity as a reliable biomarker. The novel PERCEPT neurostimulator enables chronic neuronal sensing in clinical routine. Our findings pave the way for a personalized precision-medicine approach to neurostimulation.

Erastin is a ferroptosis inducer that has shown promising cytotoxic effects in various types of cancers, including NSCLC. Celastrol is a triterpene extracted from the Tripterygium wilfordii that exhibits potential anticancer activity. However, the side effects of celastrol are severe and limit its clinical application. Combination therapy is a promising strategy to overcome the compensatory mechanisms and unwanted off-target effects. In the present study, we found that erastin synergized with celastrol to induce cell death at nontoxic concentrations. The combined treatment with celastrol and erastin significantly increased reactive oxygen species (ROS) generation, disrupted mitochondrial membrane potential, and promoted mitochondrial fission. Furthermore, cotreatment with erastin and celastrol initiated ATG5/ATG7-dependent autophagy, PINK1/Parkin-dependent mitophagy, and the expression of heat shock proteins (HSPs) in an HSF1-dependent manner. HSF1 knockdown further enhanced cell death in vitro and inhibited tumor growth in vivo. Our findings indicate that the combination of celastrol with erastin may represent a novel therapeutic regimen for patients with NSCLC and warrants further clinical evaluation.

Mobile technology has the potential to assist adults with intellectual disabilities to initiate and maintain social connections in important areas of their lives, such as family, friends and work/volunteering.

The present study investigated how specific aspects of mobile device/app use are associated with the social inclusion of people with intellectual disabilities. The study also examined what background attributes were associated with particular patterns of mobile device/app use and social inclusion.

The findings revealed that the use of mobile technology among adults with intellectual disabilities was positively associated with their social inclusion with family, friends and work/volunteering. There were also some key background attributes associated with participants' use of mobile technology and the extent to which mobile technology assisted their social inclusion.

Implications for practice and policy are discussed.

Implications for practice and policy are discussed.Affective-motivational disturbances are highly inconsistent in animal pain models. The reproducibility of the open-field test in assessing anxiety, malaise or disability remains controversial despite its popularity. While traumatic, persistent or multiregional pain models are commonly considered more effective in inducing negative affect or functional impairment, the early psychobehavioral changes before pain chronification are often underexplored. Here, we aimed to clarify the fundamental relationship between hypernociception and passive distress-like behavior using a model of transient inflammatory pain. To minimize latent confounders and increase data consistency, male C57BL/6N mice were habituated to the open-field arena 6 times before receiving the unilateral intraplantar injection of prostaglandin E2 (PGE2) or vehicle. Open-field (40-min exploration) and nociceptive behavior were evaluated repeatedly along the course of hypernociception in both wild-type and transgenic mice with a known pronociceptive phenotype. To reduce subjectivity, multivariate open-field behavioral outcomes were analyzed by statistical modeling based on exploratory factor analyses, which yielded a 2-factor solution. Within 3 hr after PGE2 injection, mice developed significantly reduced center exploration (factor 1) and a marginally significant increase in their habituation tendency (factor 2), which were not apparent in vehicle-injected mice. The behavioral passivity generally improved as hypernociception subsided. Therefore, transient inflammatory irritation is sufficient to suppress mouse open-field exploratory activity. The apparent absence of late affective-motivational changes in some rodents with prolonged hypernociception may not imply a lack of preceding or underlying neuropsychological alterations. Procedural pain after invasive animal experiments, however small, should be assessed and adequately controlled as a potential research confounder.Regulatory agencies typically evaluate the efficacy and safety of new interventions and grant commercial approval based on randomized controlled trials (RCTs). Other major healthcare stakeholders, such as insurance companies and health technology assessment agencies, while basing initial access and reimbursement decisions on RCT results, are also keenly interested in whether results observed in idealized trial settings will translate into comparable outcomes in real world settings-that is, into so-called "real world" effectiveness. Unfortunately, evidence of real world effectiveness for new interventions is not available at the time of initial approval. To bridge this gap, statistical methods are available to extend the estimated treatment effect observed in a RCT to a target population. The generalization is done by weighting the subjects who participated in a RCT so that the weighted trial population resembles a target population. We evaluate a variety of alternative estimation and weight construction procedures using both simulations and a real world data example using two clinical trials of an investigational intervention for Alzheimer's disease. Our results suggest an optimal approach to estimation depends on the characteristics of source and target populations, including degree of selection bias and treatment effect heterogeneity.This work aimed to develop an efficient R1ρ dispersion imaging method for clinical studies of human knee cartilage at 3 T. Eight constant magnetizations (Mprep ) were prepared by tailoring both the duration and amplitude (ω1 ) of a fully refocused spin-lock preparation pulse. The limited Mprep dynamic range was expanded by the measure, equivalent to that with ω1  = ∞, from the magic angle location in the deep femoral cartilage. The developed protocol with Mprep  = 60% was demonstrated on one subject's bilateral and two subjects' unilateral asymptomatic knees. The repeatability of the proposed protocol was estimated by two repeated scans with a three-month gap for the last two subjects. The synthetic R1ρ and R2 derived from R1ρ dispersions were compared with the published references using state-of-the-art R1ρ and R2 mapping (MAPSS). The proposed protocol demonstrated good ( less then 5%) repeatability quantified by the intra- and intersubject coefficients of variation in the femoral and tibial cartilage. The synthetic R1ρ (1/s) and the references were comparable in the femoral (23.0 ± 5.3 versus 24.1 ± 3.8, P = 0.67) and the tibial (29.1 ± 8.8 versus 27.1 ± 5.1, P = 0.62), but not the patellar (16.5 ± 4.9 versus 22.7 ± 1.6, P  less then  0.01) cartilage. The same trends were also observed for the current and the previous R2 . In conclusion, the developed R1ρ dispersion imaging scheme has been revealed to be not only efficient but also robust for clinical studies of human knee cartilage at 3 T.

Australian disability services must comply with quality standards defined by federal government. Standards are abstract, focus on paperwork and rarely describe what good service quality looks like in practice. This research explored frontline day service staff's perceptions of good service quality to identify ways that it may be better monitored.

Using a constructivist grounded theory methodology, semi-structured interviews were conducted with 9 frontline staff from 3-day services. Interviews were recorded, transcribed and analysed for themes using constant comparison and line-by-line coding.

Five categories of good practice were identified collaborative hands-on leadership, well-planned services, respect for people with intellectual disabilities and their carers, a culture of continuous improvement and professionalization of the support worker role.

Results align with research undertaken in accommodation services for people with intellectual disabilities, suggesting commonalities in frontline staff's perceptions of quality in both day and accommodation services.

Patients with public insurance were less likely to undergo reconstruction than patients with private insurance (OR = 2.99, p less then 0.001). White patients were more likely to undergo reconstruction (OR = 0.62, p = 0.02). Patients who lived 10-20 miles and 20-40 miles from UCMC were more likely to undergo reconstruction (OR = 1.93, p = 0.01; OR = 3.06, p less then 0.001). White patients and patients with private insurance are disproportionately undergoing breast reconstruction after mastectomy.

Paraneoplastic neurological syndromes with Hu-antibodies (Hu-PNS) are immune-mediated disorders in patients with malignancies, most frequently small cell lung cancer, affecting both the peripheral and central nervous system (CNS). In Hu-PNS, brainstem and cerebellar involvement are common. Here, we assessed whether eye-movement disturbances can be used for diagnosis and monitoring of CNS involvement in Hu-PNS.

Twenty-nine patients with Hu-PNS (17 females; mean age, 63.2years,) and 14 healthy age-matched controls (seven females; mean age, 60.2years) were included. Saccadic and smooth pursuit eye movements in response to visual stimuli were recorded with video-oculography. Eye movements were scored quantitatively (number of correction saccades, saccadic intrusions, and saccades during fixation period) and qualitatively by two eye-movement experts. In 20 patients, up to three follow-up measurements were made during subsequent hospital visits with fixed 4-week intervals. Disease course was assessed using the modified Rankin Scale.
