3, deletion in Xq22.1, and deletion in 17p13.3) were identified. Conclusion These findings have implications for our understanding of the approach to genetic testing and counseling of patients affected with seizures and epilepsy disorders. The overall diagnostic yield of exome/genome sequencing in our cohort was 23%. The main characteristic is genetic heterogeneity, supporting NGS technology as a suitable testing approach for seizures and epilepsy disorders. Genetic counseling for newly identified disease-causing variants depends on the pedigree interpretation, within the context of disease penetrance and variable expressivity.Objective This study estimated trajectories of health-related quality of life (HRQOL) over a 10-year period among children newly diagnosed with epilepsy. We also modeled the characteristics of children, parents, and families associated with each identified trajectory. Methods Data came from the HERQULES (Health-Related Quality of Life in Children With Epilepsy Study), a Canada-wide prospective cohort study of children (aged 4-12 years) with newly diagnosed epilepsy. Parents reported on their children's HRQOL at diagnosis, and at 0.5-, 1-, 2-, 8-, and 10-year follow-ups using the Quality of Life in Childhood Epilepsy Questionnaire-55. Trajectories of HRQOL were identified using latent class growth models. Characteristics of children, parents, and families at the time of diagnosis that were associated with each trajectory were identified using multinomial logistic regression. Results A total of 367 children were included. Four unique HRQOL trajectories were identified; 11% of the cohort was characterized by low and stable scores, 18% by intermediate and stable scores, 35% by intermediate scores that increased then plateaued, and 43% by high scores that increased then plateaued. Absence of comorbidities, less severe epilepsy, and better family environment (greater satisfaction with family relationships and fewer family demands) at the time of diagnosis were associated with better long-term HRQOL trajectories. Although the analyses used estimates for missing values and accounted for any nonrandom attrition, the proportion of children with poorer HRQOL trajectories may be underestimated. Significance Children with new onset epilepsy are heterogenous and follow unique HRQOL trajectories over the long term. Overall, HRQOL improves for the majority in the first 2 years after diagnosis, with these improvements sustained over the long term.Objectives/hypothesis To examine the correlation between transoral and awake endoscopic examination and investigate their respective ability to predict outcomes of hypoglossal nerve stimulation (HGNS). Study design Retrospective cohort study at a US medical center. Methods Subjects were adults with apnea-hypopnea index (AHI) >15 events/hr who underwent HGNS according to standard indications. Eligible subjects had diagnostic preoperative sleep studies, full-night efficacy postoperative studies, as well as postoperative video recordings of transoral examination and awake endoscopy. Recordings were independently scored by two blinded reviewers. Cohen's κ coefficient, Student t test, and χ2 analyses were performed. Results Fifty-seven patients met all inclusion criteria. On average, patients were Caucasian, middle aged, and overweight. The mean preoperative AHI was 36.7 events/hr, which improved significantly to 18.3 events/hr following HGNS (P 50% and AHI less then 20 events/hr) was 49%. There was slight correlation between transoral tongue protrusion and endoscopic tongue base movement (κ = 0.10). On transoral examination, patients with minimal/moderate tongue motion achieved a greater mean AHI reduction than patients with full motion (26.0 ± 18.0 vs. 12.8 ± 24.1, P = .02). In contrast, on awake endoscopy, patients with minimal/moderate tongue motion achieved a lesser mean AHI reduction than patients with full motion (8.7 ± 19.9 vs. 22.1 ± 22.7, P = .04). Conclusions Transoral tongue protrusion bears an inverse relationship to HGNS success and correlates poorly with endoscopic tongue base movement. Endoscopic tongue base motion appears reflective of response to HGNS, with greater motion corresponding to greater AHI reduction. Level of evidence 4 Laryngoscope, 2020.In narrative synthesis of evidence, it can be the case that the only quantitative measures available concerning the efficacy of an intervention is the direction of the effect, i.e. whether it is positive or negative. In such situations, the sign test has been proposed in the literature and in recent Cochrane guidelines as a way to test whether the proportion of positive effects is favourable. I argue that the sign test is inappropriate in this context as the data are not generated according to the binomial distribution it employs. I demonstrate possible consequences for both hypothesis testing and estimation via hypothetical examples. This article is protected by copyright.

The combination of apatinib and chemotherapy improved progression-free survival in the second-line therapy of advanced NSCLC without a sensitizing mutation. This study offers a new treatment strategy for second-line treatment of such patients but requires confirmation in a larger multi-institutional trial. Background This study explored the efficacy and safety of apatinib combined with single-agent chemotherapy versus single-agent chemotherapy in the second-line treatment of advanced non-small-cell lung carcinoma (NSCLC) without driver mutations. Methods In this double-arm, open label, exploratory clinical study, we enrolled patients with unresectable locally advanced or advanced NSCLC without driver mutations that had progressed following first-line chemotherapy. The subjects were allocated into an experimental group and a control group by 21. The experimental group received apatinib combined with four cycles of docetaxel or pemetrexed until disease progression, intolerable toxicity, or discontinuation at the patient's request. The control group only received four cycles of docetaxel or pemetrexed. The primary endpoints were progression-free survival (PFS), and the secondary endpoints were overall survival (OS), disease control rate (DCR), and safety. Results Thirty-seven patients were enrolled. click here The efficacy of 33 patients was evaluated. The median PFS was 5.47 versus 2.97 months, the DCR was 95% versus 73%, and the objective response rate (ORR) was 27% versus 9% in the experimental versus control group. The OS was still under follow-up. The most common adverse effects included hypertension, hand-foot skin reaction (HFSR), and fatigue. Conclusion Apatinib combined with single-agent chemotherapy may be a novel option for second-line treatment of advanced NSCLC.Currently, there are no standardized methods for quantitatively measuring fracture repair. Physicians rely on subjective physical examinations and qualitative evaluation of radiographs to detect mineralized tissue. Since most fractures heal indirectly through a cartilage intermediate, these tools are limited in their diagnostic utility of early repair. Prior to converting to bone, cartilage undergoes hypertrophic maturation, characterized by deposition of a provisional collagen X matrix. The objective of this study was to characterize the kinetics of a novel collagen X biomarker relative to other biological measurements of fracture healing using a murine model of endochondral fracture repair in which a closed, mid-shaft tibia fracture was created using the classic drop-weight technique. Serum was collected 5-42 days post-fracture in male and female mice and compared to uninjured controls (n=8-12). Collagen X in the serum was quantified using a recently validated ELISA-based bioassay ("Cxm")1 and compared to genetic and histological markers of fracture healing and inflammation. We found the Cxm biomarker reliably increased from baseline to a statistically unique peak 14 days post fracture that then resolved to pre-fracture levels by 3 weeks following injury. The shape and timing of the Cxm curve followed the genetic and histological expression of collagen X but did not show strong correlation with local inflammatory states. Assessment of fracture healing progress is crucial to making correct and timely clinical decisions for patients. This Cxm bioassay represents a minimally invasive, inexpensive technique that could provide reliable information on the biology of the fracture to significantly improve clinical care.

We demonstrate that BCX in solution undergoes minimal structural changes during turnover. NMR spectroscopy results show that the rigid protein matrix provides a frame for fast substrate binding in multiple conformations, accompanied by slow conversion, attributed to an enzyme induced substrate distortion. A model is proposed in which the rigid enzyme takes advantage of substrate flexibility to induce a conformation that facilitates the acyl formation step of the hydrolysis reaction.Aims To characterise the peripheral inflammatory cytokine profile in people with substance use disorders (SUDs). Design Systematic review and meta-analysis. Setting Clinical studies that evaluated peripheral blood inflammatory cytokine levels in patients with SUDs and healthy controls PARTICIPANTS SUD patients and healthy controls. Measurements Pubmed and Web of Science were systematically searched for relevant studies. Two investigators independently selected studies and extracted data. A total of 77 articles were included in the meta-analysis, containing 5649 patients with SUDs and 4643 healthy controls. Data were pooled using a random effects model by the Comprehensive Meta-Analysis Version 2 software. Findings Concentrations of interleukin 6 (IL-6) in 32 studies, tumor necrosis factor-α (TNF-α) in 28 studies, IL-10 in 20 studies, IL-8 in 17 studies, C-reactive protein in 14 studies, IL-4 in 10 studies, IL-12 in 7 studies, monocyte chemoattractant protein-1 (MCP-1) in 6 studies, Tumor Necrosis Factor Receptor 2 (TNFR2) in 4 studies, and granulocyte-macrophage colony stimulating factor (GM-CSF) in 3 studies were significantly higher in patients with SUDs compared with healthy controls, while concentrations of leptin in 14 studies were significantly lower in patients with SUDs compared with healthy controls. The findings were inconclusive for the associations between interferon-γ, IL-1β, IL-2, IL-1RA, TGF-β1, G-CSF, CCL11, TGF-α and SUDs. Conclusions People with substance use disorders (SUDs) appear to have higher peripheral concentrations of IL-4, IL-6, IL-8, IL-10, IL-12, TNF-α, C-reactive protein, MCP-1, TNFR2 and GM-CSF and lower peripheral concentrations of leptin than people without SUDs. This strengthens the view that SUD is accompanied by an inflammatory response.As a highly contagious and potentially fatal disease of dogs, canine parvovirus type 2 (CPV-2) usually causes severe myocarditis and gastroenteritis, while vaccine injection has greatly reduced the incidence of CPV-2 diseases. However, there is currently a lack of simple and effective method for quantitative detection of CPV-2 in vaccine. Therefore, this study aims to prepare an accurate method to determine the CPV-2 antigen (CPV-2-Ag) in vaccine. Here a sandwich time-resolved fluorescence immunoassay (TRFIA) was established and optimized Anti-CPV-2 antibodies were immobilized on 96-well plates to capture CPV-2-Ag, and then bound together with the detection antibodies labeled with Europium(III) (Eu3+ ) chelates; finally time resolved fluorometry was employed to measure the fluorescence intensity. Vaccination was performed to evaluate the relationship between CPV-2-Ag concentration and antibody titer. The sensitivity is 1.15 mEU/mL (LogY = 1.524 + 0.8667 × LogX, R2 = 0.9933)), and the average recovery is among 91.
