4% vs 75.3% vs 4.1%), (p=0.42, 0.26, 0.80, respectively). However, the grade 3/4 myelosuppression rate in the consolidation group was higher than in the concurrent chemoradiotherapy alone group (40.4% vs 22.4%, p=0.03). For patients with >3 positive lymph nodes or patients with >2 positive lymph nodes+lymphovascular space invasion/≥1/3 stromal invasion, disease-free survival and overall survival were superior in the consolidation chemotherapy group compared with the concurrent chemoradiotherapy alone group (p2 positive lymph nodes, lymphovascular space invasion, and greater than 1/3 stromal invasion, disease-free survival and overall survival were superior with consolidation chemotherapy. However, consolidation chemotherapy was also associated with an increased grade 3/4 myelosuppression rate. selleck compound © IGCS and ESGO 2020. Re-use permitted under CC BY-NC.

HIV status is also prognostic for cancer-specific survival, but compliance with HIV screening is poor in the USA and abroad. OBJECTIVES This study aims to describe HIV screening practices in a US comprehensive cancer center. To guide quality improvement, we identify characteristics which may predict compliance with screening. STUDY DESIGN Women treated for invasive cervical cancer from January 2007 to December 2017 were identified by local cancer registry and billing data. We assessed age, race, ethnicity, insurance status, histology, stage, pregnancy, drug use, and HIV testing status. Univariate logistical regression was performed to assess predictors of completed HIV screening. RESULTS Of 492 eligible women, the cumulative screening rate was 7.6%. Race, ethnicity, histology, and funding source were not predictive of screening. selleck compound Every 5 year increase in age was associated with a lower chance of screening (OR 0.86, p=0.015), as was earlier stage at diagnosis (OR 0.43, p=0.017). link2 Pregnancy during, or antecedent to, invasive cervical cancer diagnosis was significantly more predictive of screening compliance (OR 10.57, p=0.0007). Only 8/492 (1.6%) women in the cohort were active or former drug users, but within this group HIV screening was performed more frequently (OR 22.7, p less then 0.0001). CONCLUSION Despite US and international recommendations for HIV screening in AIDS-defining cancers, compliance remains low. In our centers, factors including earlier age, advanced stage, active pregnancy at diagnosis, and any drug use history were predictive of greater compliance with screening. These data will inform a tailored intervention to improve compliance with HIV screening in our population. © IGCS and ESGO 2020. No commercial re-use. See rights and permissions.

As basic research begins to suggest potential treatments, sensitive measures of the dynamic phenotype are needed to evaluate the results of these research efforts. Here we test the hypothesis that the physiological fingerprint of Rett syndrome in a naturalistic environment differs from that of controls, and differs among genotypes within Rett syndrome. METHODS A comprehensive array of heart rate variability, cardiorespiratory coupling and cardiac repolarisation measures were evaluated from an existing database of overnight and daytime inhome ambulatory recordings in 47 cases and matched controls. RESULTS Differences between girls with Rett syndrome and matched controls were apparent in a range of autonomic measures, and suggest a shift towards sympathetic activation and/or parasympathetic inactivation. Daily temporal trends analysed in the context of circadian rhythms reveal alterations in amplitude and phase of diurnal patterns of autonomic balance. Further analysis by genotype class confirms a graded presentation of the Rett syndrome phenotype such that patients with early truncating mutations were most different from controls, while late truncating and missense mutations were least different from controls. CONCLUSIONS Comprehensive autonomic measures from extensive inhome physiological measurements can detect subtle variations in the phenotype of girls with Rett syndrome, suggesting these techniques are suitable for guiding novel therapies. © Author(s) (or their employer(s)) 2020.

Published by BMJ.Accurate massively parallel sequencing (MPS) of genetic variants is key to many areas of science and medicine, such as cataloging population genetic variation and diagnosing genetic diseases. Certain genomic positions can be prone to higher rates of systematic sequencing and alignment bias that limit accuracy, resulting in false positive variant calls. Current standard practices to differentiate between loci that can and cannot be sequenced with high confidence utilize consensus between different sequencing methods as a proxy for sequencing confidence. These practices have significant limitations, and alternative methods are required to overcome them. We have developed a novel statistical method based on summarizing sequenced reads from whole-genome clinical samples and cataloging them in "Incremental Databases" that maintain individual confidentiality. link2 Allele statistics were cataloged for each genomic position that consistently showed systematic biases with the corresponding MPS sequencing pipeline. We found systematic biases present at ∼1%-3% of the human autosomal genome across five patient cohorts. link3 We identified which genomic regions were more or less prone to systematic biases, including large homopolymer flanks (odds ratio = 23.29-33.69) and the NIST high confidence genomic regions (odds ratio = 0.154-0.191). We confirmed our predictions on a gold-standard reference genome and showed that these systematic biases can lead to suspect variant calls within clinical panels. link3 Our results recommend increased caution to address systematic biases in whole-genome sequencing and alignment. This study provides the implementation of a simple statistical approach to enhance quality control of clinically sequenced samples by flagging variants at suspect loci for further analysis or exclusion. © 2020 Freeman et al.; Published by Cold Spring Harbor Laboratory Press.OBJECTIVE To analyse the association between anti-carbamylated protein antibodies (Anti-CarP) and interstitial lung disease (ILD) in rheumatoid arthritis (RA) patients. METHODS Cross-sectional study including RA patients fulfilling the 2010 ACR/EULAR criteria. The main population comprised two groups (1) RA patients diagnosed with RA-ILD (RA-ILD group); (2) RA patients without ILD (non-ILD RA group). Non-ILD RA patients in whom ILD was suspected underwent a diagnostic work-up and, if ILD was diagnosed, were switched to the RA-ILD group. ILD was diagnosed by high-resolution computed tomography and confirmed by a multidisciplinary committee. An independent replication sample was also obtained. Three Anti-CarP IgG autoantibodies against fetal calf serum (Anti-FCS), fibrinogen (Anti-Fib) and chimeric fibrine/filagrine homocitrullinated peptide (Anti-CFFHP) and one Anti-CarP IgA against FCS (Anti-FCS-IgA) were determined by home-made ELISA. Associations between Anti-CarP and ILD were analysed using multivariable ld permissions.

Studies on patients with connective tissue diseases were not considered. selleck compound Our aim was to assess the impact of this definition on atherosclerotic vascular events (AVEs) in systemic lupus erythematosus. PATIENTS METHODS Individuals from the Toronto Lupus Clinic with at least 2 years of follow-up and no prior AVE were divided in three groups according to their mean blood pressure (BP) over that period (≥140/90 mm Hg, 130-139/80-89 mm Hg and less then 130/80 mm Hg). They were followed until the first occurrence of an AVE (fatal or non-fatal coronary artery disease, cerebrovascular event and peripheral vascular disease) or last visit. Groups were compared as per the baseline atherosclerotic risk factors. A multivariable time-dependent analysis was performed to adjust for the presence of other risk factors. RESULTS Of 1532 patients satisfying the inclusion criteria, 155 (10.1%) had a BP ≥140/90 mm Hg, 316 (20.6%) 130-139/80-89 mm Hg and 1061 (69.3%) were normotensives. After a mean follow-up of 10.8 years, 124 AVEs were documented. The incidence rates were 18.9, 11.5 and 4.5 per 1000 patient-years for the three groups, respectively (p=0.0007 between the 130-139/80-89 mm Hg group and the normotensives). A mean BP of 130-139/80-89 mm Hg over the first 2 years was independently associated with the occurrence of AVEs (HR 1.73, 95% CI 1.13 to 2.65, p=0.011). CONCLUSION Patients with lupus with a sustained mean BP of 130-139/80-89 mm Hg over 2 years had a significantly higher incidence of AVEs compared with normotensive individuals. This BP level should be the target for antihypertensive therapy to minimise their cardiovascular risk. © Author(s) (or their employer(s)) 2020. No commercial re-use. link2 See rights and permissions.

METHODS Destabilisation of the medial meniscus (DMM) surgery was performed in 10-week-old wild type and AMP-activated protein kinase (AMPK)α1 knockout (KO) mice. Metformin (4 mg/day in drinking water) was given, commencing either 2 weeks before or 2 weeks after DMM surgery. Mice were sacrificed 6 and 12 weeks after DMM surgery. OA phenotype was analysed by micro-computerised tomography (μCT), histology and pain-related behaviour tests. AMPKα1 (catalytic alpha subunit of AMPK) expression was examined by immunohistochemistry and immunofluorescence analyses. link3 The OA phenotype was also determined by μCT and MRI in non-human primates. RESULTS Metformin upregulated phosphorylated and total AMPK expression in articular cartilage tissue. Mild and more severe cartilage degeneration was observed at 6 and 12 weeks after DMM surgery, evidenced by markedly increased Osteoarthritis Research Society Interts and permissions.

Moreover, failure of α-cells to increase glucagon secretion in response to falling blood glucose concentrations compromises the defense against hypoglycemia, a common complication in diabetes therapy. However, the mechanisms underlying glucose regulation of glucagon secretion are poorly understood and likely involve both α-cell-intrinsic and intra-islet paracrine signaling. Among paracrine factors, glucose-stimulated release of the GABA metabolite γ-hydroxybutyric acid (GHB) from pancreatic β-cells might mediate glucose suppression of glucagon release via GHB receptors on α-cells. However, the direct effects of GHB on α-cell signaling and glucagon release have not been investigated. Here, we found that GHB (4-10 μM) lacked effects on the cytoplasmic concentrations of the secretion-regulating messengers Ca2+ and cAMP in mouse α-cells. Glucagon secretion from perifused mouse islets was also unaffected by GHB at both 1 and 7 mM glucose.
