    Bibliographical Detective Work: William Camden‘s Remains Concerning Britain

    Get PDF
    In the present discussion of William Camden‘s Remains Concerning Britain, heraldry has as its counterpart the study of the heredity of the English language. Both are essential to Camden‘s text, in content as well as in form. Prior to these discussions of priority, however, we must begin with the precursor work which the Remains complements, Camden‘s Britannia. Chorographical rather than historical, the Britannia describes Britain‘s geography in order to explore the country‘s history. In the present investigation I adopt Camden‘s method in reverse, beginning with the historical context of Camden‘s work in order to situate a discussion of the physical text of the Remains

    Palamedes

    This thesis offers a syncretic, synoptic account of Palamedes from the Trojan War. It delineates three interpretive modes: (1) that Palamedes was present all along; (2) that later poets inserted him into the Trojan narrative, either as an archetypal intellectual figure, or as Odysseus’s double; (3) that Palamedes was present only as Odysseus’s imaginary Doppelgänger. The thesis accounts for Palamedes’s scarce attention in classical texts by way of Lacanian and—via Otto Rank—Freudian psychoanalytic theory, as well as by Slavoj Žižek’s adoption of the “vanishing mediator.” After tracing a potential textual genealogy from Palamedes to Malory’s Palomydes, the thesis concludes with a reading of Palamedes’s implied presence in Inferno 26

    Food supplementation among HIV-infected adults in Sub-Saharan Africa: Impact on treatment adherence and weight gain

    Get PDF
    This is the author's manuscript of an article published in the Proceedings of the Nutrition Society.Sub-Saharan Africa has the highest proportion of undernourished people in the world, along with the highest number of people living with HIV and AIDS. Thus, as a result of high levels of food insecurity many HIV patients are also undernourished. The synergism between HIV and undernutrition leads to poor treatment adherence and high mortality rates. Undernutrition has a debilitating effect on the immune system due to key nutrient deficiencies and the overproduction of reactive species (oxidative stress), which causes rapid HIV progression and the onset of AIDS. Therapeutic food supplementation used in the treatment of severe acute malnutrition is being applied to HIV palliative care; however, little biochemical data exist to highlight its impact on oxidative stress and immune recovery

    OBJECTIVE: To determine the efficacy and safety of eculizumab for patients with atypical haemolytic uraemic syndrome (aHUS), compared with current treatment options. DESIGN: A systematic review was performed according to the general principles of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. All study designs were included, except case histories. PARTICIPANTS: All patients diagnosed with aHUS were included; no age restrictions were used. INTERVENTIONS: Eculizumab compared with current treatment options. IDENTIFICATION OF STUDIES: 12 databases were searched. Additional searches were performed through the Food and Drug Administration (FDA) and the Electronic Medicines Compendium websites, Google internet searches and contacting clinical experts. Reference lists of relevant articles were checked for additional studies. RESULTS: 2 small, uncontrolled prospective multinational, multicentre studies and one small uncontrolled multinational, multicentre retrospective study were included. No meta-analyses were performed. Compared with baseline measures, thrombotic microangiopathy event-free status was achieved in 84% of patients in the prospective studies. Adverse events, as documented by enrolling investigators were frequent, with upper-respiratory tract infection affecting a third of patients. No deaths or episodes of meningitis or meningococcal septicaemia occurred in the prospective studies. Results of the study extension phases up to 114 weeks indicate that the benefits of the treatment are sustained. CONCLUSIONS: Eculizumab is clinically effective for the treatment of aHUS. Further research is needed to evaluate eculizumab, ideally using patient-related clinical outcomes. If randomised studies are not feasible, study investigators should ensure that the threat of bias is minimised in future studies of eculizumab with respect to the reporting of patient recruitment and selection

    Early parenting interventions to prevent internalising problems in children and adolescents: a global systematic review and network meta-analysis

    Get PDF
    QUESTION: We compared the effectiveness of different types of parenting interventions based on an a priori taxonomy, and the impact of waitlists versus treatment as usual (TAU), in reducing child internalising problems. STUDY SELECTION AND ANALYSIS: We conducted a systematic review and network meta-analysis of published and unpublished randomised controlled trials (RCTs) until 1 October 2022 that investigated parenting interventions with children younger than 4 years. EXCLUSION CRITERIA: studies with children born preterm, with intellectual disabilities, or families receiving support for current abuse, neglect, and substance misuse. We assessed the certainty of evidence using the Confidence in Network Meta-Analysis framework. We used random-effects network meta-analysis to estimate standardised mean differences (SMDs) with 95% credible intervals (CrIs). FINDINGS: Of 20 520 citations identified, 59 RCTs (18 349 participants) were eligible for the network meta-analysis. Parenting interventions focusing on the dyadic relationship (SMD: -0.26, 95% CrI: -0.43 to -0.08) and those with mixed focus (-0.09, -0.17 to -0.02) were more effective in reducing internalising problems than TAU at the first time point available. All interventions were more effective than waitlist, which increased the risk of internalising problems compared with TAU (0.36, 0.19 to 0.52). All effects attenuated at later follow-ups. Most studies were rated as with 'high risk' or 'some concerns' using the Risk of Bias Assessment Tool V.2. There was no strong evidence of effect modification by theoretically informed components or modifiers. CONCLUSIONS: We found preliminary evidence that relationship-focused and mixed parenting interventions were effective in reducing child internalising problems, and the waitlist comparator increased internalising problems with implications for waiting times between referral and support. Considering the high risk of bias of most studies included, the findings from this meta-analysis should be interpreted with caution. PROSPERO registration number CRD42020172251

    Is group cognitive behaviour therapy for postnatal depression evidence-based practice? A systematic review

    Get PDF
    Background: There is evidence that psychological therapies including cognitive behaviour therapy (CBT) may be effective in reducing postnatal depression (PND) when offered to individuals. In clinical practice, this is also implemented in a group therapy format, which, although not recommended in guidelines, is seen as a cost-effective alternative. To consider the extent to which group methods can be seen as evidence-based, we systematically review and synthesise the evidence for the efficacy of group CBT compared to currently used packages of care for women with PND, and we discuss further factors which may contribute to clinician confidence in implementing an intervention. Methods: Seventeen electronic databases were searched. All full papers were read by two reviewers and a third reviewer was consulted in the event of a disagreement on inclusion. Selected studies were quality assessed, using the Cochrane Risk of Bias Tool, were data extracted by two reviewers using a standardised data extraction form and statistically synthesised where appropriate using the fixed-effect inverse-variance method. Results: Seven studies met the inclusion criteria. Meta-analyses showed group CBT to be effective in reducing depression compared to routine primary care, usual care or waiting list groups. A pooled effect size of d = 0.57 (95% CI 0.34 to 0.80, p < 0.001) was observed at 10–13 weeks post-randomisation, reducing to d = 0.28 (95% CI 0.03 to 0.53, p = 0.025) at 6 months. The non-randomised comparisons against waiting list controls at 10–13 weeks was associated with a larger effect size of d = 0.94 (95% CI 0.42 to 1.47, p < 0.001). However due to the limitations of the available data, such as ill-specified definitions of the CBT component of the group programmes, these results should be interpreted with caution. Conclusions: Although the evidence available is limited, group CBT was shown to be effective. We argue, therefore, that there is sufficient evidence to implement group CBT, conditional upon routinely collected outcomes being benchmarked against those obtained in trials of individual CBT, and with other important factors such as patient preference, clinical experience, and information from the local context taken into account when making the treatment decision

    First direct measurements of formaldehyde flux via eddy covariance: implications for missing in-canopy formaldehyde sources

    We report the first observations of formaldehyde (HCHO) flux measured via eddy covariance, as well as HCHO concentrations and gradients, as observed by the Madison Fiber Laser-Induced Fluorescence Instrument during the BEACHON-ROCS 2010 campaign in a rural, Ponderosa Pine forest northwest of Colorado Springs, CO. A median noon upward flux of ~80 &amp;mu;g m&lt;sup&gt;&amp;minus;2&lt;/sup&gt; h&lt;sup&gt;&amp;minus;1&lt;/sup&gt; (~24 ppt&lt;sub&gt;v&lt;/sub&gt; m s&lt;sup&gt;&amp;minus;1&lt;/sup&gt;) was observed with a noon range of 37 to 131 &amp;mu;g m&lt;sup&gt;&amp;minus;2&lt;/sup&gt; h&lt;sup&gt;&amp;minus;1&lt;/sup&gt;. Enclosure experiments were performed to determine the HCHO branch (3.5 &amp;mu;g m&lt;sup&gt;-2&lt;/sup&gt; h&lt;sup&gt;&amp;minus;1&lt;/sup&gt;) and soil (7.3 &amp;mu;g m&lt;sup&gt;&amp;minus;2&lt;/sup&gt; h&lt;sup&gt;&amp;minus;1&lt;/sup&gt;) direct emission rates in the canopy. A zero-dimensional canopy box model, used to determine the apportionment of HCHO source and sink contributions to the flux, underpredicted the observed HCHO flux by a factor of 6. Simulated increases in concentrations of species similar to monoterpenes resulted in poor agreement with measurements, while simulated increases in direct HCHO emissions and/or concentrations of species similar to 2-methyl-3-buten-2-ol best improved model/measurement agreement. Given the typical diurnal variability of these BVOC emissions and direct HCHO emissions, this suggests that the source of the missing flux is a process with both a strong temperature and radiation dependence
