Intracranial recordings with stereoelectroencephalography (SEEG) aims at defining the epileptogenic zone in patients with pharmacoresistant epilepsy. Currently used techniques for depth electrode implantation include stereotactic frame-based and navigated frameless applications, both either conventional or robot-assisted. Safety and diagnostic effectiveness depend on accuracy of implantation.

To evaluate the planning experience, accuracy of stereotactic electrode placement as well as accuracy predictors with the use of latest generation planning software.

Retrospective study of 15 consecutive patients who received depth electrodes using the Leksell stereotactic frame, after planning with Elements (Brainlab, Munich, Germany). For each electrode, we calculated the entry point error (EPE) as lateral deviation and target point error (TPE) both as lateral deviation and distance to tip. Multivariate regression analysis and computation of 95% confidence intervals using the bootstrap method were applied for statistical analysis and evaluation of accuracy predictors.

The mean EPE, lateral deviation at TP and distance to tip at TP were 0.6 ±0.5 mm, 1.1 ±0.7 mm and 1.5 ±0.8 mm respectively. Order of implantation (1-6 vs. >6) is predictor for distance to tip at TP and length of electrode predictor for the lateral deviation at TP. Localization of electrode generally did not correlate to error, but insular electrodes were significantly less accurate than lobar ones.

Combination of frame-based stereotaxy with latest generation planning software may offer a better planning and implantation experience. Accuracy predictors should be analyzed and be considered for the improvement of accuracy and safety of SEEG implantation methods.

This study aimed to review the cases of giant adenomas that were operated on from 2012 to 2020 and to analyze the epidemiological profile, complications, and resection rates using the transseptal/transnasal endoscopy technique. We also compared the results with data from revised literature.

This is an observational, retrospective study includes a review of the medical records of 26 patients diagnosed with giant adenomas (diameter >4cm or volume >10cm

) who underwent 28 surgical procedures.

Of the 57 patients operated for pituitary adenoma, 26 (50.8%) had giant adenomas. The mean volume was 17.28cm

(95% confidence interval [CI], 8.3359-26.2241). Moreover, 64.28% of the patients were graded Knosp 3 (p<0.0001). Most cases were of nonsecretory adenomas (88.46%). Visual impairment was present in 89.2% of the patients and hormonal deficit and headache affected 53.5% of them. The visual impairment improved in 60% of the patients. The most common surgical complication was cerebrospinal fluid fistula (10.71%). Tumor resection >90% was achieved in 53.56% of the cases, and the mean resection rate was 78.36% (95% CI, 71.316-87.956).

The endoscopic endonasal technique is a good treatment option for giant adenomas, showing satisfactory optic apparatus decompression rates and a low incidence of complications when performed by surgeons with expertise in this approach.

Spontaneous intracerebral hemorrhage (SICH) is a subtype of stroke associated with high mortality and devastating disabilities. Therefore, identifying non-invasive biomarkers for SICH would have a tremendous clinical impact. MicroRNAs (miRNAs) are non-coding single-stranded RNAs containing 21-23 nucleotides that control the activity of various protein-coding genes through post-transcriptional repression. In this systematic review, we report the recent clinical evidence on the role of miRNAs as biomarkers for the prediction, prognosis, early detection, and risk stratification of SICH.

We conducted a systematic search of PubMed, PubMed Central, MEDLINE, and Embase databases and included only full-text peer-reviewed articles published in English.

We included 10 studies comprising seven case-control studies, two cohort studies, and one cross-sectional study, among which we found 27 altered miRNAs, suggesting their role as biomarkers for the early detection of ICH. Additionally, the expression of 34 miRNAs wIndeed, miRNA expression was associated with a poor prognosis of SICH and correlated with the predicted risk of stroke but was not specific to a stroke subtype. Further studies are needed, especially on the therapeutic potential of miRNAs and their target RNAs in SICH.Contezolid is a novel oxazolidinone antibiotic with good antibacterial activity against gram-positive bacteria including methicillin-resistant Staphylococcus aureus. For the purpose to further characterize the pharmacokinetics of contezolid and its major metabolite M2, accurate and rapid ultra-performance liquid chromatography-tandem mass spectrometric assays (UPLC-MS/MS) were developed and validated for simultaneous quantification of contezolid and M2 in human plasma and urine. The plasma samples were pretreated by liquid-liquid extraction. The automated solid phase extraction method was used to preprocess urine samples. ACQUITY UPLC® BEH C8 (2.1 mm × 100 mm, 1.7 µm) column was used to separate the analytes with a gradient mobile phase of acetonitrile and water at a flow rate of 0.4 mL/min. The calibration curves showed good linearity over the concentration ranges of 0.0100-5.00 µg/mL for contezolid in plasma and urine, 0.00200-1.00 µg/mL in plasma and 0.0200-10.0 µg/mL in urine for M2, respectively. For both plasma and urine assays, the intra- and inter-batch accuracy and precision were within 15% for all quality control levels, including the lower limit of quantitation. The methods were fully validated and successfully applied to a pharmacokinetic study of contezolid tablets in subjects with moderate hepatic impairment.In this study, a temperature-sensitive molecularly imprinted polymer was prepared by using the bifunctional monomer with the critical phase transition characteristics. Infrared spectrometry, scanning electron microscopy, and specific surface area testing were used to characterize the polymers. Then, the recognizing properties of the polymers were studied. Based on the prepared smart polymers, an SPE-HPLC analytical method for the determination of quinolizidine alkaloids in the extracts of Sophora flavescens was established and verified. Finally, the smart polymers were applied to the enrichment of quinolizidine alkaloids in plant extracts. By changing the temperature and solvents of the solid phase extraction conditions, the extraction process can increase the concentration of quinolizidine alkaloids by 4.3 to 5.2 folds. The extraction process has mild conditions and less time consumption, avoiding the use of a large number of toxic reagents, which indicate that the extraction process are more efficient and environmentally friendly.

To improve understanding as well as uptake of health educational material, it should be tailored to informational needs, offer intuitive modes of interaction, and present credible evidence for health claims. Dialogue systems go some way in meeting these requirements, as they emulate interactive and intuitive person-to-person communication. However, most works do not offer a formal model nor modelling process to structure dialogue content, and do not focus on ensuring credibility.

We propose an Extended Model of Argument (EMA) dialogue model and modelling process to support educational dialogue systems. In this dialogue model, computerized arguments directly offer evidence for health claims. EMA further offers "dialogue by design", where argument structures and interrelations are dynamically leveraged to offer dialogues, instead of relying on predefining discourse flows. We implemented an EMA-based dialogue education system for Juvenile Idiopathic Arthritis (JIA). We performed a qualitative evaluation withhe following the ability of EMA to offer credible and appropriate dialogues; and, in general, the utility of dialogue systems to educate JIA patients and their families. In future work, we will revise the system based on evaluation feedback, and perform a more extensive evaluation with patients and caregivers.Muscle dysmorphia (MD) is a severe psychiatric illness; however, little is known regarding risk factors for MD development. Conformity to masculine norms may represent a risk factor for MD, but research has yet to establish temporal ordering for these relationships. Masculine discrepancy stress (distress at not amounting to masculine stereotypes) could represent a mechanism underlying these relationships. Therefore, the current study examined longitudinal relationships between conformity to masculine norms, masculine discrepancy stress, and MD symptoms. Almonertinib datasheet Participants were 272 men displaying elevated MD symptoms who completed self-report questionnaires at three timepoints. An autoregressive cross-lagged mediation model was specified to examine relationships between conformity to masculine norms and MD symptoms and test if masculine discrepancy stress mediated these relationships. Masculine discrepancy stress did not mediate relationships between masculine norms and MD symptoms. However, MD symptoms predicted increased masculine discrepancy stress, and conformity to masculine norms was related to MD symptoms. MD symptoms were both a predictor and outcome of masculine norms, and signs for relationships differed on the masculine norm endorsed. Conformity to masculine norms may represent a risk factor and outcome for MD symptoms. If clinicians provide clients with tools to reduce rigid adherence to masculine identities, this may prevent MD symptom development.

To assess the causality of the associations between interleukins (ILs) and rheumatoid arthritis (RA) using Mendelian randomization (MR) design.

Genetic instruments and summary-level data for ten ILs were obtained from three genome-wide association meta-analyses. Corresponding data on RA were obtained from a meta-analysis of 22 genome-wide association studies (14,361 cases and 43,923 controls) and the FinnGen consortium (6236 cases, 4596 seropositive cases, 1937 seronegative cases, and 172,834 controls). Forward and reverse MR analyses were performed.

The odds ratios (ORs) of RA were 2.08 (95% confidence interval (CI), 1.56-2.77; p<0.001), 2.14 (95% CI, 1.85-2.49; p<0.001), and 0.95 (95% CI, 0.92-0.97; p<0.001) for one standard deviation increase in genetically predicted IL-1β, IL-6 and IL-6 receptor antagonist (IL-6ra) levels, respectively. There were suggestive associations of genetically predicted IL-1 receptor antagonist (IL-1ra) (OR, 0.85, 95% CI, 0.76, 0.96; p=0.010) and IL-18 (OR, 1.07, 95% CI, 1.00, 1.15; p=0.043) levels with RA risk. Subtype-specific associations were observed for seropositive RA (IL-1β, IL-1ra, and IL-6) and seronegative RA (IL-2 receptor alpha subunit, IL-8, and IL-18). Reverse MR analysis found a suggestive association between genetic liability to RA and IL-6 receptor antagonist (change 0.015; 95% CI, 0.003-0.028; p=0.015).

This MR study suggests that long-term IL-1 and IL-6 inhibition may reduce the risk of RA, particularly seropositive RA. Upregulations of ILs involved in IL-6 signaling pathways appears to be downstream effects of RA, which supports the blocking IL-6 treatment for RA.
