Expression of PD‐L1, indoleamine 2,3‐dioxygenase and the immune microenvironment in gastric adenocarcinoma

Pallavi A Patil, Andrew M Blakely, Kara A Lombardo, Jason T Machan, more

Aims The tumour microenvironment is increasingly important in several tumours. We studied the relationship of key players of immune microenvironment with clinicopathological parameters in gastric adenocarcinomas. Methods and results Tissue microarrays were constructed from gastrectomy specimens, 2004–13. Immunohistochemistry was performed for programmed cell death ligand 1 (PD‐L1), indoleamine...

Clinicopathologic and gene expression analysis of initial biopsies from patients with eosinophilic esophagitis refractory to therapy

Ayesha S. Siddique, David C. Corney, Shamlal Mangray, Kara A. Lombardo, more

Human Pathology > 2017 > 68 > C > 79-86

Some patients with eosinophilic esophagitis (EoE) do not respond to therapy. The clinicopathologic characteristics and gene expression profile at time of presentation could help predict response to therapy. Refractory EoE was defined as persistence of symptoms and biopsies with histologic features of EoE after 6 months of therapy with proton pump inhibitors and topical corticosteroids. Initial biopsies...

Using digital mood monitoring technology to support the assessment, engagement and empowerment of young people presenting to mental health services with mood instability

M. Dubad, S. Marwaha, C. Winsper

European Psychiatry > 2017 > 41 > S > S545

Digital mood-monitoring technology, such as mood-monitoring applications, is increasingly advocated within clinical research and is a potentially effective method to engage and empower youth. However, limited evidence is available on this type of technology.(1) To assess the evidence for the use of mobile mood-monitoring applications in youth; (2) to explore what available smartphone application would...

Objective The incidence and outcome of first‐episode substance‐induced psychotic disorder (SIPD) are unclear. The study aimed to compare the 1‐year outcomes of those given a SIPD diagnosis by clinicians compared to other psychosis diagnoses in a first‐episode cohort.

Multi objective load frequency control using hybrid bacterial foraging and particle swarm optimized PI controller

Sukhwinder Singh Dhillon, J.S. Lather, S. Marwaha

International Journal of Electrical Power & Energy Systems > 2016 > 79 > C > 196-209

Excessive load demand with reliability in power availability, demands for interconnection of large number of generating units over existing tie lines. Due to sudden change in demand, the power transfer over existing tie lines working close to their thermal limits results in low frequency power oscillations. Thus, in modern power systems the study of mitigation of these frequency oscillations is more...

Journal of the American College of Surgeons > 2016 > 222 > 6 > 984-991

In 2011, the ACGME limited duty hours for residents. Although studies evaluating the 2011 policy have not shown improvements in general measures of morbidity or mortality, these outcomes might not reflect changes in specialty-specific practice patterns and secondary quality measures.All trauma admissions from July 2009 through June 2013 at an academic Level I trauma center were evaluated for 5 primary...

J. Rampling, V. Furtado, C. Winsper, S. Marwaha, more

European Psychiatry > 2016 > 34 > C > 17-28

For people with mental illness that are violent, a range of interventions have been adopted with the aim of reducing violence outcomes. Many of these interventions have been borrowed from other (offender) populations and their evidence base in a Serious Mental Illness (SMI) population is uncertain.To aggregate the evidence base for non-pharmacological interventions in reducing violence amongst adults...

Journal of Affective Disorders > 2016 > 190 > C > 764-771

Affective instability (AI), childhood trauma, and mental illness are linked, but evidence in affective disorders is limited, despite both AI and childhood trauma being associated with poorer outcomes. Aims were to compare AI levels in bipolar disorder I (BPI) and II (BPII), and major depressive disorder recurrent (MDDR), and to examine the association of AI and childhood trauma within each diagnostic...

Software's using ontology as their knowledge base are of due importance now a days due to their synergism with agents and Semantic Web Architecture. Ontologies provide domain language by defining domain concepts and relationships between them which is ultimately meaningful to both humans and machines. This is IEEE standard Web Ontology Language (OWL). Taxonomies are well-defined hierarchy existing...

S. Marwaha, L. Balbuena, C. Winsper, R. Bowen

European Psychiatry > 2015 > 30 > Supplement 1 > 1312

Levels of mood instability (MI) appear to be high in people with depression, but temporal precedence and possible mechanisms are unknown. We tested hypotheses that: i] MI will be associated with a diagnosis of depression cross-sectionally; ii] MI will predict new onset and maintenance of depression prospectively; iii] the association between MI and depression will be mediated by sleep problems...

Mood as a mediator of the link between child sexual abuse and psychosis

S. Marwaha, P. Bebbington

Social Psychiatry and Psychiatric Epidemiology > 2015 > 50 > 4 > 661-663

The significance of affective changes in psychosis is increasingly acknowledged, as is the role of early traumatic events. In a previous paper, using data from the English Adult Psychiatric Morbidity Survey 2007 (APMS2007), strong associations between child sexual abuse (CSA) and psychosis were demonstrated, with some evidence of mediation by affect. In the current paper, we subjected the same dataset...

S. Marwaha, M. Broome, P. Bebbington, E. Kuipers, more

European Psychiatry > 2014 > 29 > S1 > 1

We used British national survey data to test specific hypotheses that mood instability 1) is associated with psychosis and individual psychotic phenomena, 2) predicts the later emergence of auditory hallucinations and paranoid ideation, and 3) mediates the link between child sexual abuse and psychosis.We analysed data from the 2000 and 2007 UK national surveys of psychiatric morbidity (N=8580 and...
