“How Can a Woman Who Has Been Raped Be Believed?”: Andrea Dworkin, Sexual Violence and the Ethics of Belief

In June 2000, Andrea Dworkin, an American feminist activist and author, published an account of being raped in a Paris hotel room a year earlier. The story was met with widespread disbelief, including from feminist readers. This article explores the reasons for this disbelief, asking how and why narratives of rape are granted – or denied – truth status by their readers. The article argues for understanding the conferral of belief as a narrative transaction involving the actions of both narrator and reader. It posits that Dworkin was widely seen as an unreliable narrator but argues that for ideologically charged narratives such as rape narratives judgements of reliability and belief inevitably draw upon the normative standpoint of the reader. I suggest that there are opposing criteria for establishing the truth of rape narratives; a ‘factual’ or legal model, which sees rape narratives as requiring scrutiny, and an ‘experiential’ model, located within certain strands of feminist politics, which emphasises the ethical importance of believing women’s narratives. The article finishes with a consideration of the place of belief within an ethics of reading and reception of rape narratives

Inhaled liposomal ciprofloxacin in patients with non-cystic fibrosis bronchiectasis and chronic lung infection with Pseudomonas aeruginosa (ORBIT-3 and ORBIT-4):two phase 3, randomised controlled trials

In patients with non-cystic fibrosis bronchiectasis, lung infection with Pseudomonas aeruginosa is associated with frequent pulmonary exacerbations and admission to hospital for treatment, reduced quality of life, and increased mortality. Although inhaled antibiotics are conditionally recommended for long-term management of non-cystic fibrosis bronchiectasis with frequent exacerbations, there is no approved therapy. We investigated the safety and efficacy of inhaled liposomal ciprofloxacin (ARD-3150) in two phase 3 trials. ORBIT-3 and ORBIT-4 were international, randomised, double-blind, placebo-controlled, phase 3 trials run concurrently in similar geographical regions. Eligible patients had non-cystic fibrosis bronchiectasis, had had at least two pulmonary exacerbations treated with antibiotics in the previous 12 months, and had a history of chronic P aeruginosa lung infection. Patients were randomly assigned (2:1) to receive either ARD-3150 or placebo. ARD-3150 (3 mL liposome encapsulated ciprofloxacin 135 mg and 3 mL free ciprofloxacin 54 mg) or 6 mL placebo (3 mL dilute empty liposomes mixed with 3 mL of saline) was self-administered once daily for six 56-day treatment cycles, for 48 weeks. The primary endpoint was time to first pulmonary exacerbation from the date of randomisation to week 48. We did primary and secondary efficacy, safety, and microbiology analyses on the full analysis population, which comprised all randomised patients who received at least one dose of study drug. ORBIT-3 and ORBIT-4 are registered with ClinicalTrials.gov, numbers NCT01515007 and NCT02104245, respectively. Between March 31, 2014, and Aug 19, 2015, we screened 514 patients in ORBIT-3 and 533 patients in ORBIT-4. The full analysis populations consisted of 278 patients in ORBIT-3 (183 patients received at least one dose of ARD-3150 and 95 received placebo) and 304 patients in ORBIT-4 (206 patients received at least one dose of ARD-3150 and 98 received placebo). In ORBIT-4, the median time to first pulmonary exacerbation was 230 days in the ARD-3150 group compared with 158 days in the placebo group, a statistically significant difference of 72 days (hazard ratio [HR] 0·72 [95% CI 0·53-0·97], p=0·032). In ORBIT-3, the median time to first pulmonary exacerbation was 214 days in the ARD-3150 group and 136 days in the placebo group, a non-statistically significant difference of 78 days (HR 0·99 [95% CI 0·71-1·38], p=0·97). In a pooled analysis of data from both ORBIT-3 and ORBIT-4, the median time to first pulmonary exacerbation was 222 days in the ARD-3150 group and 157 days in the placebo group, a non-statistically significant difference of 65 days (0·82 [0·65-1·02], p=0·074). The numbers of adverse events and serious adverse events were similar in both groups in ORBIT-3 and ORBIT-4. In patients with non-cystic fibrosis bronchiectasis and chronic P aeruginosa lung infection requiring antibiotic therapy in the preceding year, ARD-3150 led to a significantly longer median time to first pulmonary exacerbation compared with placebo in ORBIT-4, but not in ORBIT-3 or the pooled analysis. Inconsistency between the trials suggests further research is needed into the heterogeneity of non-cystic fibrosis bronchiectasis and optimal outcome measures for inhaled antibiotics.

Bayesian estimation of tobramycin exposure in cystic fibrosis

Fixed tobramycin (mg/kg) dosing is often inappropriate in patients with cystic fibrosis (CF), as pharmacokinetics are highly variable. The area under the concentration-time curve (AUC) is an exposure metric suited to monitoring in this population. Bayesian strategies to estimate AUC have been available for over 20 years but are not standard practice in the clinical setting. To assess their suitability for use in clinical practice, three AUC estimation methods using limited sampling were compared to measured true exposure by using intensive sampling tobramycin data. Adults prescribed once daily intravenous tobramycin had eight concentrations taken over 24 h. An estimate of true exposure within one dosing interval was calculated using the trapezoidal method and compared to three alternate estimates determined using (i) a two-sample log-linear regression (LLR) method (local hospital practice); (ii) a Bayesian estimate using one concentration (AUC(1)); and (iii) a Bayesian estimate using two concentrations (AUC(2)). Each method was evaluated against the true measured exposure by a Bland-Altman analysis. Twelve patients with a median (range) age and weight of 25 (18 to 36) years and 66.5 (51 to 76) kg, respectively, were recruited. There was good agreement between the true exposure and the three alternate estimates of AUC, with a mean AUC bias of < 10 mg/liter center dot h in each case, i.e., -8.2 (LLR), 3.8 (AUC(1)), and 1.0 (AUC(2)). Bayesian analysis-based and LLR estimation methods of tobramycin AUC are equivalent to true exposure estimation. All three methods may be suitable for use in the clinical setting; however, a one-sample Bayesian method may be most useful in ambulatory patients for which coordinating blood samples is difficult. Suitably powered, randomized clinical trials are required to assess patient outcomes

Adult Non-Cystic Fibrosis Bronchiectasis Is Characterised by Airway Luminal Th17 Pathway Activation

METHODS: Th17 pathway cytokines were quantified in bronchoalveolar lavage fluid (BALF), and gene expression of IL-17A, IL-1β, IL-8 and IL-23 determined from endobronchial biopsies (EBx) in 41 stable bronchiectasis subjects and 20 healthy controls. Relationships between IL-17A levels and infection status, important clinical measures and subsequent Pseudomonas aeruginosa infection were determined. RESULTS: BALF levels of all Th17 cytokines (median (IQR) pg/mL) were significantly higher in bronchiectasis than control subjects, including IL-17A (1.73 (1.19, 3.23) vs. 0.27 (0.24, 0.35), 95% CI 1.05 to 2.21, p<0.0001) and IL-23 (9.48 (4.79, 15.75) vs. 0.70 (0.43, 1.79), 95% CI 4.68 to 11.21, p<0.0001). However, BALF IL-17A levels were not associated with clinical measures or airway microbiology, nor predictive of subsequent P. aeruginosa infection. Furthermore, gene expression of IL-17A in bronchiectasis EBx did not differ from control. In contrast, gene expression (relative to medians of controls) in bronchiectasis EBx was significantly higher than control for IL1β (4.12 (1.24, 8.05) vs 1 (0.13, 2.95), 95% CI 0.05 to 4.07, p = 0.04) and IL-8 (3.75 (1.64, 11.27) vs 1 (0.54, 3.89), 95% CI 0.32 to 4.87, p = 0.02) and BALF IL-8 and IL-1α levels showed significant relationships with clinical measures and airway microbiology. P. aeruginosa infection was associated with increased levels of IL-8 while Haemophilus influenzae was associated with increased IL-1α. CONCLUSIONS AND CLINICAL RELEVANCE: Established adult non-CF bronchiectasis is characterised by luminal Th17 pathway activation, however this pathway may be relatively less important than activation of non-antigen-specific innate neutrophilic immunity

Prognostic indices for early mortality in ischaemic stroke – meta-analysis

Objectives: Several models have been developed to predict mortality in ischaemic stroke. We aimed to evaluate systematically the performance of published stroke prognostic scores. Methods: We searched MEDLINE and EMBASE in February 2014 for prognostic models (published between 2003 and 2014) used in predicting early mortality (<6 months) after ischaemic stroke. We evaluated discriminant ability of the tools through meta-analysis of the area under the curve receiver operating characteristic curve (AUROC) or c-statistic. We evaluated the following components of study validity: collection of prognostic variables, neuroimaging, treatment pathways and missing data. Results: We identified 18 articles (involving 163 240 patients) reporting on the performance of prognostic models for mortality in ischaemic stroke, with 15 articles providing AUC for meta-analysis. Most studies were either retrospective, or post hoc analyses of prospectively collected data; all but three reported validation data. The iSCORE had the largest number of validation cohorts (five) within our systematic review and showed good performance in four different countries, pooled AUC 0.84 (95% CI 0.82–0.87). We identified other potentially useful prognostic tools that have yet to be as extensively validated as iSCORE – these include SOAR (2 studies, pooled AUC 0.79, 95% CI 0.78–0.80), GWTG (2 studies, pooled AUC 0.72, 95% CI 0.72–0.72) and PLAN (1 study, pooled AUC 0.85, 95% CI 0.84–0.87). Conclusions: Our meta-analysis has identified and summarized the performance of several prognostic scores with modest to good predictive accuracy for early mortality in ischaemic stroke, with the iSCORE having the broadest evidence base

Bronchiectasis:new therapies and new perspectives

European Respiratory Society guidelines for the management of adult bronchiectasis highlight the paucity of treatment options available for patients with this disorder. No treatments have been licensed by regulatory agencies worldwide, and most therapies used in clinical practice are based on very little evidence. Development of new treatments is needed urgently. We did a systematic review of scientific literature and clinical trial registries to identify agents in early-to-late clinical development for bronchiectasis in adults. In this Review, we discuss the mechanisms and potential roles of emerging therapies, including drugs that target airway and systemic inflammation, mucociliary clearance, and epithelial dysfunction. To ensure these treatments achieve success in randomised clinical trials-and therefore reach patients-we propose a reassessment of the current approach to bronchiectasis. Although understanding of the pathophysiology of bronchiectasis is at an early stage, we argue that bronchiectasis is a heterogeneous disease with many different biological mechanisms that drive disease progression (endotypes), and therefore the so-called treatable traits approach used in asthma and chronic obstructive pulmonary disease could be applied to bronchiectasis, with future trials targeted at the specific disease subgroups most likely to benefit

New therapies for the prevention and treatment of exacerbations of bronchiectasis

PURPOSE OF REVIEW: Exacerbations of bronchiectasis have a major impact on quality of life, healthcare costs, and long-term risk of complications. Preventing exacerbations is one of the major goals of treatment. Bronchiectasis is increasingly recognized and the impact of bronchiectasis exacerbations on daily clinical practice is also increasing.RECENT FINDINGS: Preventing bronchiectasis exacerbations are dependent on appropriate risk assessment, identifying the patients at highest risk to rationally target preventive therapies. Inhaled and oral antibiotic treatments can target chronic bacterial infection which is one of the major risk factors for exacerbation. Although the data is weak, airway clearance is an important part of long-term management including in patients with frequent exacerbations. Anti-inflammatory therapies such as inhaled corticosteroids do not currently have a major role outside comorbid chronic obstructive pulmonary disease and asthma, but further studies are required.SUMMARY: Treatment of acute exacerbations involves prompt administration of antibiotic therapy with usually 14 days of oral, or for severe exacerbations, intravenous antibiotics. The role of corticosteroids is not established and there is little data on the optimal management approach for acute exacerbations. Home intravenous therapy can reduce healthcare costs and improve patient satisfaction with care. A number of large randomized controlled trials are currently enrolling or have recently completed raising the possibility that the treatment paradigm may change in the near future.</p
