Multicenter, prospective validation of a phenotypic algorithm to guide carbapenemase testing in carbapenem-resistant Pseudomonas aeruginosa using the ERACE-PA global surveillance program

Background: Carbapenemase-producing, carbapenem-resistant Methods: CRPA isolates were collected during the Enhancing Rational Antimicrobials for Results: A total of 807 CRPA were assessed, and 464 isolates met the algorithm criteria described above. Overall, testing was reduced by 43% compared with testing all CRPA. Carbapenemase-positive isolates missed by the algorithm were largely driven by Guiana extended spectrum (GES). Addition of the criterion of imipenem- or meropenem-resistant plus ceftolozane/tazobactam-nonsusceptible decreased the number of CP-CRPA missed by the algorithm (21 vs 40 isolates, respectively), reducing number of isolates tested by 39%. Conclusions: Application of the initial algorithm (imipenem- or meropenem-resistant plus ceftazidime-nonsusceptible plus cefepime-nonsusceptible) performed well in a global cohort, with 33% phenotypically carbapenemase-positive isolates. The addition of imipenem- or meropenem-resistant plus ceftolozane/tazobactam-nonsusceptible reduced the number of phenotypically carbapenemase-positive isolates missed and may be useful in areas with a prominence of GES

Living in the epilepsy treatment gap in rural South India: A focused ethnography of women and problems associated with stigma

In India, women with epilepsy face unique challenges. A focused ethnography of six women within the epilepsy treatment gap was conducted in rural South India. Women were asked to describe their day-to-day lives. Data were collected through open-ended, semistructured interview questions, participant observation, and field notes. Thematic analysis was done. The disease-related stigma contributed to the women's physical, psychological, and emotional struggles; the women and their family members made every effort to conceal the disease. Educational interventions to create awareness could help women seek effective treatments for their seizures, thereby reducing the stigma and improving the quality of their lives

Women’s Experiences with Epilepsy Treatment in Southern India: A Focused Ethnography

Women with epilepsy in rural southern India often do not receive anti-epilepsy drugs (AEDs) or take these drugs regularly, but little is known about how they experience the epilepsy treatment they do receive. The purpose of this study was to provide an in-depth description of the treatment experiences of women in this region who had been diagnosed with epilepsy but who do not consistently take AEDs. Focused ethnography was conducted using participant observation and in-depth interviews with six women with epilepsy, eight of their family members, and two traditional healers. The women's treatment experiences are best described as living at the intersection of Western allopathic ("English") medicine and traditional healing practices-approaches that could be complementary or conflicting. The women revealed a variety of perceived barriers to the use of "English" medicine. Health care professionals should appreciate the dynamic interplay of the two treatment approaches and consider all cultural, social, and economic factors that influence the women's treatment experiences

Beliefs around luck : confirming the empirical conceptualization of beliefs around luck and the development of the Darke and Freedman beliefs around luck scale

The current study developed a multi-dimensional measure of beliefs around luck. Two studies introduced the Darke and Freedman beliefs around luck scale where the scale showed a consistent 4 component model (beliefs in luck, rejection of luck, being lucky, and being unlucky) across two samples (n = 250; n = 145). The scales also show adequate reliability statistics and validity by ways of comparison with other measures of beliefs around luck, peer and family ratings and expected associations with measures of personality, individual difference and well-being variables

Association Between Cytokines and Liver Histology in Children with Nonalcoholic Fatty Liver Disease.

BackgroundReliable non-invasive markers to characterize inflammation, hepatocellular ballooning, and fibrosis in nonalcoholic fatty liver disease (NAFLD) are lacking. We investigated the relationship between plasma cytokine levels and features of NAFLD histology to gain insight into cellular pathways driving NASH and to identify potential non-invasive discriminators of NAFLD severity and pattern.MethodsCytokines were measured from plasma obtained at enrollment in pediatric participants in NASH Clinical Research Network studies with liver biopsy-proven NAFLD. Cytokines were chosen a priori as possible discriminators of NASH and its components. Minimization of Akaike Information Criterion (AIC) was used to determine cytokines retained in multivariable models.ResultsOf 235 subjects, 31% had "Definite NASH" on liver histology, 43% had "Borderline NASH", and 25% had NAFLD but not NASH. Total plasminogen activator inhibitor 1 (PAI1) and activated PAI1 levels were higher in pediatric participants with Definite NASH and with lobular inflammation. Interleukin-8 (IL-8) was higher in those with stage 3-4 fibrosis and lobular inflammation. sIL-2rα was higher in children with stage 3-4 fibrosis and portal inflammation. In multivariable analysis, PAI1 variables were discriminators of Borderline/Definite NASH, definite NASH, lobular inflammation and ballooning. IL-8 increased with steatosis and fibrosis severity; sIL-2rα increased with fibrosis severity and portal inflammation. IL-7 decreased with portal inflammation and fibrosis severity.ConclusionsPlasma cytokines associated with histology varied considerably among NASH features, suggesting promising avenues for investigation. Future, more targeted analysis is needed to identify the role of these markers in NAFLD and to evaluate their potential as non-invasive discriminators of disease severity

FIRE (facilitating implementation of research evidence) : a study protocol

Research evidence underpins best practice, but is not always used in healthcare. The Promoting Action on Research Implementation in Health Services (PARIHS) framework suggests that the nature of evidence, the context in which it is used, and whether those trying to use evidence are helped (or facilitated) affect the use of evidence. Urinary incontinence has a major effect on quality of life of older people, has a high prevalence, and is a key priority within European health and social care policy. Improving continence care has the potential to improve the quality of life for older people and reduce the costs associated with providing incontinence aids

The politics of access in fieldwork: Immersion, backstage dramas and deception

YesGaining access in fieldwork is crucial to the success of research, and may often be problematic because it involves working in complex social situations. This paper examines the intricacies of access, conceptualizing it as a fluid, temporal and political process that requires sensitivity to social issues and to potential ethical choices faced by both researchers and organization members. Our contribution lies in offering ways in which researchers can reflexively negotiate the challenges of access by: 1. Underscoring the complex and relational nature of access by conceptualizing three relational perspectives – instrumental, transactional and relational – proposing the latter as a strategy for developing a diplomatic sensitivity to the politics of access; 2. Explicating the political, ethical and emergent nature of access by framing it as an ongoing process of immersion, backstage dramas, and deception; and 3. Offering a number of relational micropractices to help researchers negotiate the complexities of access. We illustrate the challenges of gaining and maintaining access through examples from the literature and from Rafael’s attempts to gain access to carry out fieldwork in a Police Force

Macrophages Are Required for Dendritic Cell Uptake of Respiratory Syncytial Virus from an Infected Epithelium

We have previously shown that the respiratory syncytial virus [RSV] can productively infect monocyte derived dendritic cells [MoDC] and remain dormant within the same cells for prolonged periods. It is therefore possible that infected dendritic cells act as a reservoir within the airways of individuals between annual epidemics. In the present study we explored the possibility that sub-epithelial DCs can be infected with RSV from differentiated bronchial epithelium and that in turn RSV from DCs can infect the epithelium. A dual co-culture model was established in which a differentiated primary airway epithelium on an Air Liquid Interface (ALI) was cultured on a transwell insert and MoDCs were subsequently added to the basolateral membrane of the insert. Further experiments were undertaken using a triple co-culture model in which in which macrophages were added to the apical surface of the differentiated epithelium. A modified RSV [rr-RSV] expressing a red fluorescent protein marker of replication was used to infect either the MoDCs or the differentiated epithelium and infection of the reciprocal cell type was assessed using confocal microscopy. Our data shows that primary epithelium became infected when rr-RSV infected MoDCs were introduced onto the basal surface of the transwell insert. MoDCs located beneath the epithelium did not become infected with virus from infected epithelial cells in the dual co-culture model. However when macrophages were present on the apical surface of the primary epithelium infection of the basal MoDCs occurred. Our data suggests that RSV infected dendritic cells readily transmit infection to epithelial cells even when they are located beneath the basal layer. However macrophages appear to be necessary for the transmission of infection from epithelial cells to basal dendritic cells
