'Commemorating the Irish Famine' explores the history of the 1840s Irish Famine in visual representation, commemoration and collective memory from the 19th century until the present, across Ireland and the nations of its diaspora, explaining why since the 1990s the Famine past has come to matter so much in our present.

Thymic stromal lymphopoietin, a cytokine, has been implicated in allergic sensitization and post-sensitization effector pathways. In this study, an antibody interrupting TSLP signaling improved lab-induced early and late asthmatic responses without modifying baseline airway obstruction. Asthma is a chronic inflammatory disease of the airways that is characterized by recurrent episodes of wheezing, breathlessness, chest tightness, and cough. The cause of this disorder is multifactorial and is influenced by both genetic and environmental mechanisms, 1 , 2 with environmental allergens as an important cause. 2 , 3 Inhalation of allergens by patients with atopic asthma induces some of the manifestations of asthma, including reversible airflow obstruction, airway hyperresponsiveness, and eosinophilic and basophilic airway inflammation. Allergen-inhalation challenge has become the predominant model for the evaluation of asthmalike responses in many species. 4 , 5 Thymic stromal lymphopoietin (TSLP) is an epithelial-cell–derived cytokine that . . .

In patients with asthma who had elevated blood eosinophil levels and marginal asthma control despite treatment with high-dose inhaled or oral glucocorticoids, asthma exacerbations were reduced in those receiving a monoclonal antibody that binds to and inactivates interleukin-5. Severe asthma affects less than 10% of patients with asthma and is associated with substantial morbidity and mortality and a large fraction of the health care costs among patients with asthma. 1 – 3 Despite available care, recurrent asthma exacerbations are a major issue in a subgroup of patients with eosinophilic airway inflammation. 4 – 6 Mepolizumab, a humanized monoclonal antibody against interleukin-5, selectively inhibits eosinophilic inflammation 7 , 8 and reduces the number of eosinophils in both sputum and blood, resulting in a reduction in exacerbations and in the need for treatment with systemic glucocorticoids. 7 – 12 In the Dose Ranging Efficacy and Safety with Mepolizumab . . .

A ground-breaking collection of essays that explore how the material and visual cultures of Ireland and its diaspora (including painting, engraving, photography, devotional objects, ritual, drama, film, television and graphic novels) intersect with the multiple impacts and experiences of the Irish Famine, from the 1840s to the present day.

Eosinophilia is associated with worsening asthma severity and decreased lung function, with increased exacerbation frequency. We assessed the safety and efficacy of benralizumab, a monoclonal antibody against interleukin-5 receptor α that depletes eosinophils by antibody-dependent cell-mediated cytotoxicity, for patients with severe, uncontrolled asthma with eosinophilia. We did a randomised, double-blind, parallel-group, placebo-controlled phase 3 study at 374 sites in 17 countries. We recruited patients (aged 12–75 years) with a physician-based diagnosis of asthma for at least 1 year and at least two exacerbations while on high-dosage inhaled corticosteroids and long-acting β2-agonists (ICS plus LABA) in the previous year. Patients were randomly assigned (1:1:1) by an interactive web-based voice response system to benralizumab 30 mg either every 4 weeks (Q4W) or every 8 weeks (Q8W; first three doses every 4 weeks) or placebo Q4W for 48 weeks as add on to their standard treatment. Patients were stratified 2:1 according to blood eosinophil counts of at least 300 cells per μL and less than 300 cells per μL. All patients and investigators involved in patient treatment or clinical assessment were masked to treatment allocation. The primary endpoint was annual exacerbation rate ratio versus placebo, and key secondary endpoints were prebronchodilator forced expiratory volume in 1 s (FEV1) and total asthma symptom score at week 48, for patients with blood eosinophil counts of at least 300 cells per μL. Efficacy analyses were by intention to treat (based on the full analysis set); safety analyses included patients according to study drug received. This study is registered with ClinicalTrials.gov, number NCT01928771. Between Sept 19, 2013, and March 16, 2015, 2681 patients were enrolled, 1205 of whom met the study criteria and were randomly assigned: 407 to placebo, 400 to benralizumab 30 mg Q4W, and 398 to benralizumab 30 mg Q8W. 267 patients in the placebo group, 275 in the benralizumab 30 mg Q4W group, and 267 in the benralizumab 30 mg Q8W group had blood eosinophil counts at least 300 cells per μL and were included in the primary analysis population. Compared with placebo, benralizumab reduced the annual asthma exacerbation rate over 48 weeks when given Q4W (rate ratio 0·55, 95% CI 0·42–0·71; p<0·0001) or Q8W (0·49, 0·37–0·64; p<0·0001). Both benralizumab dosing regimens significantly improved prebronchodilator FEV1 in patients at week 48 compared with placebo (least-squares mean change from baseline: Q4W group 0·106 L, 95% CI 0·016–0·196; Q8W group 0·159 L, 0·068–0·249). Compared with placebo, asthma symptoms were improved by the Q8W regimen (least-squares mean difference −0·25, 95% CI −0·45 to −0·06), but not the Q4W regimen (−0·08, −0·27 to 0·12). The most common adverse events were worsening asthma (105 [13%] of 797 benralizumab-treated patients vs 78 [19%] of 407 placebo-treated patients) and nasopharyngitis (93 [12%] vs 47 [12%]). These results confirm the efficacy and safety of benralizumab for patients with severe asthma and elevated eosinophils, which are uncontrolled by high-dosage ICS plus LABA, and provide support for benralizumab to be an additional option to treat this disease in this patient population.

In a trial of minimally invasive cerebral hematoma removal within 24 hours after onset of hemorrhage, functional outcomes were better with surgery than with medical treatment, particularly among patients with lobar hemorrhages.

Treatment outcomes for multidrug-resistant Mycobacterium Tuberculosis (MDRTB) are generally poor compared to drug sensitive disease. We sought to estimate treatment outcomes and identify risk factors associated with poor outcomes in patients with MDRTB. We performed a systematic search (to December 2008) to identify trials describing outcomes of patients treated for MDRTB. We pooled appropriate data to estimate WHO-defined outcomes at the end of treatment and follow-up. Where appropriate, pooled covariates were analyzed to identify factors associated with worse outcomes. Among articles identified, 36 met our inclusion criteria, representing 31 treatment programmes from 21 countries. In a pooled analysis, 62% [95% CI 57-67] of patients had successful outcomes, while 13% [9]-[17] defaulted, 11% [9]-[13] died, and 2% [1]-[4] were transferred out. Factors associated with worse outcome included male gender 0.61 (OR for successful outcome) [0.46-0.82], alcohol abuse 0.49 [0.39-0.63], low BMI 0.41[0.23-0.72], smear positivity at diagnosis 0.53 [0.31-0.91], fluoroquinolone resistance 0.45 [0.22-0.91] and the presence of an XDR resistance pattern 0.57 [0.41-0.80]. Factors associated with successful outcome were surgical intervention 1.91 [1.44-2.53], no previous treatment 1.42 [1.05-1.94], and fluoroquinolone use 2.20 [1.19-4.09]. We have identified several factors associated with poor outcomes where interventions may be targeted. In addition, we have identified high rates of default, which likely contributes to the development and spread of MDRTB.
