    Borges and the Third Man: Toward an Interpretation of ‘Unánime noche’ in “The Circular Ruins”

    I aim to show how the enigmatic phrase 'Unánime noche' in the famous first sentence of “The Circular Ruins” is inextricably linked to the story’s last words. Toward this purpose, I argue—against plausible foundational interpretations of the story—for a nonfoundational reading of the text and, moreover, that Borges’s use of ‘unánime’ (one soul) can be understood as one character or one form; namely, as an archetype of “Dreamanity” that leads to a vertiginous Third Man regress

    BACKGROUND: A growing Muslim population in the UK suggests the need for healthcare professionals (HCPs) to gain a better understanding of how the Islamic faith influences health related perceptions and healthcare seeking behaviour. Although some researchers have explored the experiences of Muslim women as recipients of healthcare, little attention has been paid to the challenges HCPs face as service providers on a day-to-day basis whilst caring for Muslim women. The aim of this study was to investigate HPCs lived experiences of providing maternity care for Muslim women. METHOD: Data was collected through twelve semi-structured one-to-one qualitative interviews with HCPs in a large National Health Service (NHS) maternity unit located in the North West of England. Interview participants included Community and specialist clinic (e.g. clinic for non-English speakers), Midwives in a variety of specialist roles (7), Gynaecology Nurses (2), Breastfeeding Support Workers (2) and a Sonographer (1). The audio-recorded interviews were transcribed and analysed thematically. RESULTS: The majority of participants expressed an understanding of some religious values and practices related to Muslim women, such as fasting the month of Ramadhan and that pregnant and breastfeeding women are exempt from this. However, HCPs articulated the challenges they faced when dealing with certain religious values and practices, and how they tried to respond to Muslim women's specific needs. Emerging themes included: 1) HCPs perceptions about Muslim women; 2) HCPs understanding and awareness of religious practices; 3) HCPs approaches in addressing and supporting Muslim women's religious needs; 4) Importance of training in providing culturally and religiously appropriate woman-centred care. CONCLUSION: Through this study we gained insight into the day-to-day experiences of HCPs providing care provision for Muslim women. HCPs showed an understanding of the importance of religious and cultural practices in addressing the needs of Muslim women as part of their role as maternity care providers. However, they also identified a need to develop training programmes that focus on cultural and religious practices and their impact on women's health care needs. This will help support HCPs in overcoming the challenges faced when dealing with needs of women from different backgrounds

    A systematic review of the evidence for single stage and two stage revision of infected knee replacement

    BACKGROUND: Periprosthetic infection about the knee is a devastating complication that may affect between 1% and 5% of knee replacement. With over 79 000 knee replacements being implanted each year in the UK, periprosthetic infection (PJI) is set to become an important burden of disease and cost to the healthcare economy. One of the important controversies in treatment of PJI is whether a single stage revision operation is superior to a two-stage procedure. This study sought to systematically evaluate the published evidence to determine which technique had lowest reinfection rates. METHODS: A systematic review of the literature was undertaken using the MEDLINE and EMBASE databases with the aim to identify existing studies that present the outcomes of each surgical technique. Reinfection rate was the primary outcome measure. Studies of specific subsets of patients such as resistant organisms were excluded. RESULTS: 63 studies were identified that met the inclusion criteria. The majority of which (58) were reports of two-stage revision. Reinfection rated varied between 0% and 41% in two-stage studies, and 0% and 11% in single stage studies. No clinical trials were identified and the majority of studies were observational studies. CONCLUSIONS: Evidence for both one-stage and two-stage revision is largely of low quality. The evidence basis for two-stage revision is significantly larger, and further work into direct comparison between the two techniques should be undertaken as a priority

    Predictors of linkage to care following community-based HIV counseling and testing in rural Kenya

    Despite innovations in HIV counseling and testing (HCT), important gaps remain in understanding linkage to care. We followed a cohort diagnosed with HIV through a community-based HCT campaign that trained persons living with HIV/AIDS (PLHA) as navigators. Individual, interpersonal, and institutional predictors of linkage were assessed using survival analysis of self-reported time to enrollment. Of 483 persons consenting to follow-up, 305 (63.2%) enrolled in HIV care within 3 months. Proportions linking to care were similar across sexes, barring a sub-sample of men aged 18–25 years who were highly unlikely to enroll. Men were more likely to enroll if they had disclosed to their spouse, and women if they had disclosed to family. Women who anticipated violence or relationship breakup were less likely to link to care. Enrolment rates were significantly higher among participants receiving a PLHA visit, suggesting that a navigator approach may improve linkage from community-based HCT campaigns.Vestergaard Frandse

    Cure of ADPKD by Selection for Spontaneous Genetic Repair Events in Pkd1-Mutated iPS Cells

    Induced pluripotent stem cells (iPSCs) generated by epigenetic reprogramming of personal somatic cells have limited therapeutic capacity for patients suffering from genetic disorders. Here we demonstrate restoration of a genomic mutation heterozygous for Pkd1 (polycystic kidney disease 1) deletion (Pkd1(+/−) to Pkd1(+/R+)) by spontaneous mitotic recombination. Notably, recombination between homologous chromosomes occurred at a frequency of 1∼2 per 10,000 iPSCs. Southern blot hybridization and genomic PCR analyses demonstrated that the genotype of the mutation-restored iPSCs was indistinguishable from that of the wild-type cells. Importantly, the frequency of cyst generation in kidneys of adult chimeric mice containing Pkd1(+/R+) iPSCs was significantly lower than that of adult chimeric mice with parental Pkd1(+/−) iPSCs, and indistinguishable from that of wild-type mice. This repair step could be directly incorporated into iPSC development programmes prior to cell transplantation, offering an invaluable step forward for patients carrying a wide range of genetic disorders

    This is the final version. Available from SPIE via the DOI in this recordSPIE Astronomical Telescopes + Instrumentation conference 2020. Online OnlyIn this contribution we report on our work to increase the spectral range of the Michigan Infrared Combiner- eXeter (MIRC-X) instrument at the CHARA array to allow for dual H and J band interferometric observations. We comment on the key science drivers behind this project and the methods of characterisation and correction of instrumental birefringence and dispersion. In addition, we report on the first results from on-sky commissioning in November 2019.Science and Technology Facilities Council (STFC)European Research Council (ERC)NASANational Science Foundation (NSF

    Current sample size conventions: Flaws, harms, and alternatives

    Get PDF
    <p>Abstract</p> <p>Background</p> <p>The belief remains widespread that medical research studies must have statistical power of at least 80% in order to be scientifically sound, and peer reviewers often question whether power is high enough.</p> <p>Discussion</p> <p>This requirement and the methods for meeting it have severe flaws. Notably, the true nature of how sample size influences a study's projected scientific or practical value precludes any meaningful blanket designation of <80% power as "inadequate". In addition, standard calculations are inherently unreliable, and focusing only on power neglects a completed study's most important results: estimates and confidence intervals. Current conventions harm the research process in many ways: promoting misinterpretation of completed studies, eroding scientific integrity, giving reviewers arbitrary power, inhibiting innovation, perverting ethical standards, wasting effort, and wasting money. Medical research would benefit from alternative approaches, including established <it>value of information </it>methods, simple choices based on cost or feasibility that have recently been justified, sensitivity analyses that examine a meaningful array of possible findings, and following previous analogous studies. To promote more rational approaches, research training should cover the issues presented here, peer reviewers should be extremely careful before raising issues of "inadequate" sample size, and reports of completed studies should not discuss power.</p> <p>Summary</p> <p>Common conventions and expectations concerning sample size are deeply flawed, cause serious harm to the research process, and should be replaced by more rational alternatives.</p
