    Aim: The present study aims to explore the perception that mothers of mentally disabled children have of their family functioning, measuring: the dynamics of the familiar functioning; the perception that the parental couple has about parenting and family functioning; the similarities between fathers and mothers in the perception of these dimensions. Materials and Methods: The sample included 50 mothers of  mentally disabled children. The sample was taken from selected special school. They completed: Family Assessment tool was used to assess specific aspects of family functioning, such as problem solving, communication, roles, affective response  and involvement, behavioral control and general functioning; Family Adaptability and Cohesion Evaluation Scales to measure family adaptability and cohesion. Results: Shows that highest percentage (40%) of the sample was in the age group of 20-25years. shows that maximum percentage (68%) of mothers had average family function 20% had poor family function , and 5% very poor family function. The parents of disabled daughters showed significantly higher on following scales: cohesion, communication and satisfaction. In contrast, the parents who have male sons showed high scores in the scale of flexibility. Parents of children with autism reported higher scores than the parents of children with pervasive developmental disorders in the following scales: cohesion, communication and satisfaction. Conclusions: Children depend on their parents and caregivers for stability, safety, support, and assistance in helping them make sense of adverse events and life challenges. By strengthening community support and attending to parent and caregiver needs and well-being, family-serving professionals will be doing their utmost to ensure that the special children and their families thrive

    Increased glutamine metabolism by macrophages is associated with development of atherosclerotic lesions. Positron emission tomography/computed tomography (PET/CT) with a glutamine analog (2S,4R)-4-F-18-fluoroglutamine (F-18-FGln) allows quantification of glutamine consumption in vivo. Here, we investigated uptake of F-18-FGln by atherosclerotic lesions in mice and compared the results with those obtained using the glucose analog 2-deoxy-2-F-18-fluoro-D-glucose (F-18-FDG). Uptake of F-18-FGln and F-18-FDG by healthy control mice (C57BL/6JRj) and atherosclerotic low-density lipoprotein receptor-deficient mice expressing only apolipoprotein B100 (LDLR(-/-)ApoB(100/100)) was investigated. The mice were injected intravenously with F-18-FGln or F-18-FDG for in vivo PET/CT imaging. After sacrifice at 70 minutes post-injection, tracer uptake was analyzed by gamma counting of excised tissues and by autoradiography of aorta cryosections, together with histological and immunohistochemical analyses. We found that myocardial uptake of F-18-FGln was low. PET/CT detected lesions in the aortic arch, with a target-to-background ratio (SUVmax, aortic arch/SUVmean, blood) of 1.95 +/- 0.42 (mean +/- standard deviation). Gamma counting revealed that aortic uptake of F-18-FGln by LDLR(-/-)ApoB(100/100) mice (standardized uptake value [SUV], 0.35 +/- 0.06) was significantly higher than that by healthy controls (0.20 +/- 0.08, P = 0.03). More detailed analysis by autoradiography revealed that the plaque-to-healthy vessel wall ratio of F-18-FGln (2.90 +/- 0.42) was significantly higher than that of F-18-FDG (1.93 +/- 0.22, P = 0.004). Immunohistochemical staining confirmed that F-18-FGln uptake in plaques co-localized with glutamine transporter SLC7A7-positive macrophages. Collectively these data show that the F-18-FGln PET tracer detects inflamed atherosclerotic lesions. Thus, exploiting glutamine consumption using F-18-FGln PET may have translational relevance for studying atherosclerotic inflammation

    Dissecting the polygenic basis of atherosclerosis via disease-associated cell state signatures

    Coronary artery disease (CAD) is a pandemic disease where up to half of the risk is explained by genetic factors. Advanced insights into the genetic basis of CAD require deeper understanding of the contributions of different cell types, molecular pathways, and genes to disease heritability. Here, we investigate the biological diversity of atherosclerosis-associated cell states and interrogate their contribution to the genetic risk of CAD by using single-cell and bulk RNA sequencing (RNA-seq) of mouse and human lesions. We identified 12 disease-associated cell states that we characterized further by gene set functional profiling, ligand-receptor prediction, and transcription factor inference. Importantly, Vcam1+ smooth muscle cell state genes contributed most to SNP-based heritability of CAD. In line with this, genetic variants near smooth muscle cell state genes and regulatory elements explained the largest fraction of CAD-risk variance between individuals. Using this information for variant prioritization, we derived a hybrid polygenic risk score (PRS) that demonstrated improved performance over a classical PRS. Our results provide insights into the biological mechanisms associated with CAD risk, which could make a promising contribution to precision medicine and tailored therapeutic interventions in the future.publishedVersionPeer reviewe

    Evaluation of appendicitis risk prediction models in adults with suspected appendicitis

    Background Appendicitis is the most common general surgical emergency worldwide, but its diagnosis remains challenging. The aim of this study was to determine whether existing risk prediction models can reliably identify patients presenting to hospital in the UK with acute right iliac fossa (RIF) pain who are at low risk of appendicitis. Methods A systematic search was completed to identify all existing appendicitis risk prediction models. Models were validated using UK data from an international prospective cohort study that captured consecutive patients aged 16–45 years presenting to hospital with acute RIF in March to June 2017. The main outcome was best achievable model specificity (proportion of patients who did not have appendicitis correctly classified as low risk) whilst maintaining a failure rate below 5 per cent (proportion of patients identified as low risk who actually had appendicitis). Results Some 5345 patients across 154 UK hospitals were identified, of which two‐thirds (3613 of 5345, 67·6 per cent) were women. Women were more than twice as likely to undergo surgery with removal of a histologically normal appendix (272 of 964, 28·2 per cent) than men (120 of 993, 12·1 per cent) (relative risk 2·33, 95 per cent c.i. 1·92 to 2·84; P < 0·001). Of 15 validated risk prediction models, the Adult Appendicitis Score performed best (cut‐off score 8 or less, specificity 63·1 per cent, failure rate 3·7 per cent). The Appendicitis Inflammatory Response Score performed best for men (cut‐off score 2 or less, specificity 24·7 per cent, failure rate 2·4 per cent). Conclusion Women in the UK had a disproportionate risk of admission without surgical intervention and had high rates of normal appendicectomy. Risk prediction models to support shared decision‐making by identifying adults in the UK at low risk of appendicitis were identified

    BACKGROUND & AIMS: The interaction between HBV replication and immune modulatory effects mediated by IFNα therapy is not well understood. We characterized the impact of HBV DNA replication on the early IFNα-induced immunomodulatory mechanisms. METHODS: We interrogated the transcriptional, serum cytokine/chemokine and cellular immune profiles of 28 patients with HBeAg+ chronic HBV infection (CHB) randomly assigned to one of 4 treatment cohorts (untreated n=5, weekly dosing of 360 μg Pegasys [PegIFNα] n=11, daily dose of 300 mg Viread [tenofovir disoproxil fumarate, TDF] n=6, or a combination of both n=6). Samples were characterized at multiple early time points through day 14 of therapy, after which all patients were given standard of care (180 μg Pegasys injected subcutaneously, weekly). RESULTS: PegIFNα induced a distinct and rapid up-regulation of IFN signaling pathway that coincided with increase detection of distinct serum cytokines/chemokines (IL-15, IL-6, and CXCL-10) and the up-regulation of the frequency of proliferating NK and activated total CD8+ T cells. IFNα treatment alone did not result in rapid decay of HBV replication and was not able to restore the defective HBV-specific T cell response present in CHB patients. In addition, the IFNα immune-stimulatory effects diminished after the first dose, but this refractory effect was reduced in patients where HBV replication was simultaneously inhibited with TDF. CONCLUSIONS: We present here the first comprehensive description of the early effects of IFNα treatment on immune and viral biomarkers in HBeAg+ CHB patients. Our results show that PegIFNα-induced innate immune activation directly benefits from the suppression of HBV replication

    This phase I/IIa study (NCT02737475) evaluated the safety and activity of BMS-986178, a fully human OX40 agonist IgG1 mAb, ± nivolumab and/or ipilimumab in patients with advanced solid tumors. Patients (with non-small cell lung, renal cell, bladder, other advanced cancers) received BMS-986178 (20-320 mg) ± nivolumab (240-480 mg) and/or ipilimumab (1-3 mg/kg). The primary endpoint was safety. Additional endpoints included immunogenicity, pharmacodynamics, pharmacokinetics, and antitumor activity per RECIST version 1.1. Twenty patients received BMS-986178 monotherapy, and 145 received combination therapy in various regimens (including two patients receiving nivolumab monotherapy). With a follow-up of 1.1 to 103.6 weeks, the most common (≥5%) treatment-related adverse events (TRAEs) included fatigue, pruritus, rash, pyrexia, diarrhea, and infusion-related reactions. Overall, grade 3-4 TRAEs occurred in one of 20 patients (5%) receiving BMS-986178 monotherapy, six of 79 (8%) receiving BMS-986178 plus nivolumab, zero of two receiving nivolumab monotherapy, six of 41 (15%) receiving BMS-986178 plus ipilimumab, and three of 23 (13%) receiving BMS-986178 plus nivolumab plus ipilimumab. No deaths occurred. No dose-limiting toxicities were observed with monotherapy, and the MTD was not reached in either the monotherapy or the combination escalation cohorts. No objective responses were seen with BMS-986178 alone; objective response rates ranged from 0% to 13% across combination therapy cohorts. In this study, BMS-986178 ± nivolumab and/or ipilimumab appeared to have a manageable safety profile, but no clear efficacy signal was observed above that expected for nivolumab and/or ipilimumab
