Motor cortex stimulation (MCS) via surgically implanted electrodes has been used as an off-label treatment for chronic neuropathic pain (cNeP) but its efficacy has not been fully established. We aimed to objectively study the efficacy of MCS and characterize potential predictors of response. In this randomised, double-blind, sham-controlled, single centre trial, we recruited 18 cNeP patients who did not adequately respond to conventional treatment and had a numerical rating pain scale (NRS) score ≥ 6. Patients were initially assigned to receive three months of active ("on") or sham ("off") stimulation in a double-blind cross-over phase. This was followed by a 3-month single-blind phase, and 6 months of open-label follow-up. A meaningful response in our trial was defined as a ≥ 30% or 2-point reduction in NRS scores during active stimulation. Using Bayesian statistics, we found a 41.4% probability of response towards "on" vs. "off" MCS. The probability of improvement during active stimulation (double-blind, single-blind and open label phases) compared to baseline was of 47.2-68.5%. 39% of patients were long-term responders, 71.4% of whom had facial pain, phantom limb pain, or complex regional pain syndrome. In contrast, 72.7% of non-responders had either post-stroke pain or pain associated with brachial plexus avulsion. 39% of patients had a substantial post-operative analgesic effect after electrode insertion in the absence of stimulation. Individuals with diagnoses associated with a good postoperative outcome or those who developed an insertional effect had a near 100% probability of response to MCS. In summary, we found that approximately 40% of patients responded to MCS, particularly those who developed an insertional effect or had specific clinical conditions that seemed to predict an appropriate postoperative response.

The risk of amyloidosis during the course of ankylosing spondylitis (AS) is yet to be firmly established. We aimed to evaluate the risk, predictors, and prognostic outcomes of amyloidosis among patients with AS.

A population-based cohort study was conducted comparing AS patients (n = 5,911) with age-, sex- and ethnicity-matched control subjects (n = 29 007) with regard to incident cases of amyloidosis. Hazard ratios (HRs) and odds ratios (ORs) were estimated by Cox regression and logistic regression analyses, respectively.

The incidence rate of amyloidosis was 2.15 (95% CI, 1.09-2.82) and 0.35 (95% CI, 0.16-0.66) per 10 000 person-years among patients with AS and controls, respectively. The risk of incident amyloidosis was >6-folds higher among patients with AS relative to control subjects (adjusted HR, 6.16; 95% CI, 2.43-15.62; p< 0.001). A higher comorbidity burden (OR, 1.36; 95% CI, 1.08-1.73; p= 0.010) was found to predict an increased susceptibility to amyloidosis in AS patients. Compared with other patients with AS, those with AS and comorbid amyloidosis had a 14-fold increased risk of end-stage renal disease necessitating dialysis (adjusted HR, 14.7; 95% CI, 2.0-107.2; p= 0.008), but comparable risk of all-cause mortality (adjusted HR, 2.16; 95% CI, 0.69-6.71; p= 0.174).

Patients with AS are at an increased risk of amyloidosis. AS-associated amyloidosis is associated with an elevated risk of dialysis dependence. Awareness of the burden and consequences of this complication may be of help for rheumatologists managing patients with AS.

To determine whether the introduction of biological disease-modifying anti-rheumatic drugs (bDMARDs) was associated with reduced incidences of total hip and knee arthroplasty (THA/TKA) among patients with rheumatoid arthritis (RA) compared with osteoarthritis (OA).

Using a population-based cohort in British Columbia, Canada, RA and OA patients diagnosed between 1995-2007 were divided into semi-annual cohorts according to diagnosis date. For each cohort, we calculated 8-year incidence rates of THA and TKA. We compared levels and trends of THA/TKA incidence in RA/OA patients diagnosed during pre-bDMARDs (1995-2001) and post-bDMARDs (2003-2007) periods using interrupted time-series analysis, adjusting for baseline characteristics. Adjusted 8-year TJA incidence estimated for RA/OA cohorts diagnosed five years after bDMARDs introduction were compared with expected rates assuming no bDMARDs introduction, based on extrapolation of pre-bDMARDs trends.

We identified 60,227 RA and 288,260 OA incident cases. For cot in OA. The reduction reflects a significant improvement in RA treatment during the biological era.

Facial nerve injury after facelift is rare; hence, its treatment is poorly established. Botulinum toxin type A (BTXA) can be used to resolve the asymmetry. There is no protocol in the literature about the best timing for this treatment, injection sites or recommended dose.

Propose a protocol to guide the management of asymmetries post-facelifts.

Fifteen patients with post-rhytidectomy facial palsies were treated in the non-paralyzed side with BTXA. After analysis of the smile deviation vectors, it is possible to identify the muscles that should be treated. The dose varied from 1-2 Uv/point. Patients were examined after 15 days for outcomes evaluation, and "touch-up" if needed. Patients were re-treated after 5-6 months in case of asymmetry recurrence.

Symmetry was achieved in all cases. Six patients had definitive nerve lesions and needed to be treated every 6 months after the first session. Five patients had lesions affecting the upper third of the face, four of them were definitive nerve lesions. Two of the four patients who were treated less than 2 weeks after surgery recovered early from the post-facelift paralysis and developed reversed asymmetry due to the BTXA. In seven patients, the post-facelift asymmetry was due to neuropraxis the recovery from the nerve injury and BTXA treatment occurred symmetrically on both sides of the face in the following months, after one single session.

Asymmetries post-facelifts were successfully managed with the proposed protocol. Best time for injection was 2-4 weeks after surgery.

We assessed cross-sectionally the relative contributions of three potential mechanisms causing hypometabolism in the retrosplenial and inferior parietal cortices local molecular (amyloid and tau) pathology and atrophy, distant factors including contributions from the degenerating medial temporal lobe or molecular pathology in functionally connected regions, and the presence of the apolipoprotein E (APOE) ε4 allele. Two hundred and thirty-two amyloid-positive cognitively impaired patients from two cohorts (University of California, San Francisco, UCSF, and Alzheimer's Disease Neuroimaging Initiative, ADNI) underwent MRI and PET with FDG, amyloid-PET using [11C]-Pittsburgh Compound B, [18F]-Florbetapir, or [18F]-Florbetaben, and [18F]-Flortaucipir tau-PET within one year. Standard firmed overall associations between hypometabolism and local tau pathology and thickness and revealed associations between medial temporal degeneration and hypometabolism in retrosplenial, orbitofrontal, and anterior cingulate cortices. Finally, our data did not support hypotheses of a detrimental effect of pathology in connected regions or of an effect of the APOE ε4 allele in impaired participants. Overall, in two independent groups of patients at symptomatic stages of Alzheimer's disease, cortical hypometabolism mainly reflected structural neurodegeneration and tau, but not amyloid, pathology.Accurate prediction of drug-target interactions (DTIs) through biological data can reduce the time and economic cost of drug development. The prediction method of DTIs based on a similarity network is attracting increasing attention. Currently, many studies have focused on predicting DTIs. link2 However, such approaches do not consider the features of drugs and targets in multiple networks or how to extract and merge them. In this study, we proposed a Network EmbeDding framework in mulTiPlex networks (NEDTP) to predict DTIs. link3 NEDTP builds a similarity network of nodes based on 15 heterogeneous information networks. Next, we applied a random walk to extract the topology information of each node in the network and learn it as a low-dimensional vector. Finally, the Gradient Boosting Decision Tree model was constructed to complete the classification task. NEDTP achieved accurate results in DTI prediction, showing clear advantages over several state-of-the-art algorithms. The prediction of new DTIs was also verified from multiple perspectives. In addition, this study also proposes a reasonable model for the widespread negative sampling problem of DTI prediction, contributing new ideas to future research.

By combining immunohistochemistry, tracing studies and western-blotting, with the use of different DREADDs (Designer Receptor Exclusively Activated by Designer Drugs) and behavioural approaches in a rat model of neuropathic pain (chronic constriction injury), we explore how this comorbidity arises. To this end, we evaluated the time-dependent plasticity of noradrenergic-locus coeruleus (LC) neurons relative to the site of injury ipsilateral (LCipsi) or contralateral (LCcontra) at three different time points short- (2 days), mid- (7 days), and long-term (30-35 days from nerve injury). Nerve injury led to sensorial hypersensitivity from the onset of injury, whereas depressive-like behavior was only evident following long-term pain. Global chemogenetic blockade of the LCipsi system alone increased short-term pain sensitivity while the blockade of the LCipsi or LCcontra relieved pain-induced depression. The asymmetric contribution of LC-modules was also evident as neuropathy develops. Hence, chemogenetic blockade of the LCipsi→spinal cord projection, increased pain-related behaviours in the short-term. However, this lateralized circuit is not universal as the bilateral chemogenetic inactivation of the LC-rostral anterior cingulate cortex (rACC) pathway or the intra-rACC antagonism of alpha1- and alpha2-adrenoreceptors reversed long-term pain-induced depression. Furthermore, chemogenetic LC to spinal cord activation, mainly through LCipsi, reduced sensorial hypersensitivity irrespective of the time post-injury. Our results indicate that asymmetric activation of specific LC modules promotes early restorative-analgesia, as well as late depressive-like behavior in chronic pain and depression comorbidity.
