Fully automated real-time PCR for EGFR testing in non-small cell lung carcinoma.

Molecular testing for mutations in the EGFR gene is commonplace for patients with non-small cell lung cancer (NSCLC). These patients are often very sick and management decisions need to be made urgently. In many cases, the results of molecular testing are needed the same day, in order to start targeted therapy and allow maximum benefit for patients. The Idylla™ EGFR Mutation Test offers rapid results within three hours of requesting. This study aimed to assess the concordance of Idylla™ EGFR Mutation Test results with current standard tests. Forty formalin-fixed, paraffin-embedded NSCLC tumour cases (20 EGFR mutant and EGFR 20 wild type) were analysed by the Idylla™ EGFR Mutation Test (CE-IVD) and compared with PCR and NGS methodologies. The overall concordance between Idylla™ and standard testing was 92.5% (95% CI 80.14% to 97.42%) and the specificity of Idylla™ was 100% (95% CI 83.89% to 100%). The sensitivity was affected by loss of tumour content in tissue blocks in a small number of NGS cases; however, comparing Idylla™ with PCR alone, there was 100% concordance (95% CI 89.85% to 100%). The Idylla™ EGFR Mutation Test shows comparative accuracy to routine PCR testing for the most common EGFR mutations in NSCLC. The Idylla™ also offers significantly reduced turn-around times compared with existing modalities and therefore the platform would be a useful addition to many molecular diagnostics units

Local constructions of gender-based violence amongst IDPs in northern Uganda: analysis of archival data collected using a gender- and age-segmented participatory ranking methodology

Background Gender-based violence (GBV) is a significant problem in conflict-affected settings. Understanding local constructions of such violence is crucial to developing preventive and responsive interventions to address this issue. Methods This study reports on a secondary analysis of archived data collected as part of formative qualitative work – using a group participatory ranking methodology (PRM) – informing research on the prevalence of GBV amongst IDPs in northern Uganda in 2006. Sixty-four PRM group discussions were held with women, with men, with girls (aged 14 to 18 years), and with boys (aged 14 to 18 years) selected on a randomized basis across four internally displaced persons (IDP) camps in Lira District. Discussions elicited problems facing women in the camps, and – through structured participatory methods - consensus ranking of their importance and narrative accounts explaining these judgments. Results Amongst forms of GBV faced by women, rape was ranked as the greatest concern amongst participants (with a mean problem rank of 3.4), followed by marital rape (mean problem rank of 4.5) and intimate partner violence (mean problem rank of 4.9). Girls ranked all forms of GBV as higher priority concerns than other participants. Discussions indicated that these forms of GBV were generally considered normalized within the camp. Gender roles and power, economic deprivation, and physical and social characteristics of the camp setting emerged as key explanatory factors in accounts of GBV prevalence, although these played out in different ways with respect to differing forms of violence. Conclusions All groups acknowledged GBV to represent a significant threat - among other major concerns such as transportation, water, shelter, food and security – for women residing in the camps. Given evidence of the significantly higher risk in the camp of intimate partner violence and marital rape, the relative prominence of the issue of rape in all rankings suggests normalization of violence within the home. Programs targeting reduction in GBV need to address community-identified root causes such as economic deprivation and social norms related to gender roles. More generally, PRM appears to offer an efficient means of identifying local constructions of prevailing challenges in a manner that can inform programming

Improved Management of Stillbirth using a Care Pathway.

PurposeEach year approximately 3,200 women have a stillbirth in the UK. Although national evidence-based guidance has existed since 2010, case reviews continue to identify suboptimal clinical care and communication with parents. Inconsistencies in management include induction and management of labour and the frequency of investigation after stillbirth. The paper aims to discuss these issues.Design/methodology/approachAn audit of stillbirths was performed in 2014 in 13 maternity units in the North West of England, this confirmed variation in practice described nationally. An integrated care pathway (ICP) was developed from national guidelines to enable optimal care for the management of stillbirth, reduce variation, standardise investigations and coordinate patient-focussed care. This was launched in 2015 and updated in 2016 to resolve the issues that were apparent after implementation.FindingsEach participating unit had commenced using the ICP by May 2015. Following implementation there were changes in care, most notably from diverse methods for the induction of labour to guideline-directed induction of labour. There were trends towards better care in terms of information given, choices offered, more appropriate analgesia in labour and improved post-delivery investigation for cause. Staff feedback about the ICP was positive.Practical implicationsThe use of this ICP improved care for women who had a stillbirth and their families. Issues with implementing a changed care pathway meant that further iterations were required, ongoing improvement is expected following the refinement of the ICP.Originality/valueICPs have been used for various clinical conditions. However, this is the first example of their use in women who had a stillbirth

Variation in susceptibility to microbial lignin oxidation in a set of wheat straw cultivars:influence of genetic, seasonal and environmental factors

An alkali lignin preparation from wheat straw was found to be compatible with a previously developed nitrated lignin assay for microbial lignin oxidation, allowing comparison of the susceptibility of different wheat lignins to microbial oxidation. Alkali lignin was prepared from a panel of 18 wheat varieties, and was analysed by FT-IR spectroscopy, revealing minor variations in the lignin structure. Samples of nitrated alkali lignin were assayed against five lignin degrading bacteria: Streptomyces viridosporus, Rhodococcus jostii RHA1, Pseudomonas putida mt-2, Microbacterium phyllosphaerae, and Sphingobacterium sp. T2. Up to 5-fold variation in rates of lignin oxidation were observed between different wheat varieties, and between different bacterial strain, with Sphingobacterium sp. T2 showing consistently highest absorbance changes. Testing of wheat varieties from two consecutive harvests, and from different locations, revealed that the observed variation was due to a ombination of genetic, seasonal and environmental factors, but that some wheat varieties showed consistently higher rates of oxidation. Samples of wheat straw treated with Sphingobacterium sp. T2 were analysed by FT-IR spectroscopy after 7 and 14 days? treatment, showing changes in lignin structure versus time, consistent with lignin breakdown.publishersversionPeer reviewe

Telomere Length Shows No Association with BRCA1 and BRCA2 Mutation Status

This study aimed to determine whether telomere length (TL) is a marker of cancer risk or genetic status amongst two cohorts of BRCA1 and BRCA2 mutation carriers and controls. The first group was a prospective set of 665 male BRCA1/2 mutation carriers and controls (mean age 53 years), all healthy at time of enrolment and blood donation, 21 of whom have developed prostate cancer whilst on study. The second group consisted of 283 female BRCA1/2 mutation carriers and controls (mean age 48 years), half of whom had been diagnosed with breast cancer prior to enrolment. TL was quantified by qPCR from DNA extracted from peripheral blood lymphocytes. Weighted and unweighted Cox regressions and linear regression analyses were used to assess whether TL was associated with BRCA1/2 mutation status or cancer risk. We found no evidence for association between developing cancer or being a BRCA1 or BRCA2 mutation carrier and telomere length. It is the first study investigating TL in a cohort of genetically predisposed males and although TL and BRCA status was previously studied in females our results don't support the previous finding of association between hereditary breast cancer and shorter TL

How can we recruit more men of African or African-Caribbean ancestry into our research? Co-creating a video to raise awareness of prostate cancer risk and the PROFILE study

Background Men of African ancestry are at increased risk of developing prostate cancer (PrCa) compared to men from other backgrounds. The PROFILE study aims to understand whether genetic information can better target who needs PrCa screening. PROFILE has so far had difficulty reaching men of African or African -Caribbean ancestry to take part. In this involvement project we worked in partnership with a group of such men to co-create a video to raise awareness of PrCa risk amongst this community and promote participation in the study. Methods We recruited seven men of African or African-Caribbean ancestry who completed an initial survey on the Cancer Patients’ Voice platform. We then held an online discussion panel and maintained contact to encourage dialogue and planning of the video. Utilising a participatory approach, the ideas for the video were decided in collaboration with the panel who held expert knowledge of various communities and understood the messages that would best resonate and engage with other men of the same origins. Once the video had been edited and finalised, two members of the group expressed interest in writing up the project and are listed as co-authors. Results The video in its entirety was driven by the panel’s ideas. The choice of a barber shop setting; leading with a positive case study and highlighting the importance of men’s family members rather than a focus on scientific language, statistics or researchers were all features that were discussed and agreed upon by the panel. The men shared the video within their networks. It was placed on websites and promoted as part of a social media campaign during Black History Month. Conclusions Groups with the greater healthcare needs and the most to gain from advances in care and treatment can often be the most excluded from research participation. This is pertinent in PrCa research where men of African or African-Caribbean ancestry are at greater risk. The project gave equal power and decision making to the men and provides an example of successful inclusive involvement. The result was a unique approach to making a study video
