Public understandings of potential policy responses to health inequalities: Evidence from a UK national survey and citizens' juries in three UK cities.

A substantial body of research describes the distribution, causes and potential reduction of health inequalities, yet little scholarship examines public understandings of these inequalities. Existing work is dominated by small-scale, qualitative studies of the experiences of specific communities. As a result, we know very little about what broader publics think about health inequalities; and even less about public views of potential policy responses. This is an important gap since previous research shows many researchers and policymakers believe proposals for 'upstream' policies are unlikely to attract sufficient public support to be viable. This mixed methods study combined a nationally representative survey with three two-day citizens' juries exploring public views of health inequalities and potential policy responses in three UK cities (Glasgow, Manchester and Liverpool) in July 2016. Comparing public opinion elicited via a survey to public reasoning generated through deliberative processes offers insight into the formation of public views. The results challenge perceptions that there is a lack of public support for upstream, macro-level policy proposals and instead demonstrate support for proposals aiming to tackle health inequalities via improvements to living and working conditions, with more limited support for proposals targeting individual behavioural change. At the same time, some macro-economic proposals, notably those involving tax increases, proved controversial among study participants and results varied markedly by data source. Our analysis suggests that this results from three intersecting factors: a resistance to ideas viewed as disempowering (which include, fundamentally, the idea that health inequalities exist); the prevalence of individualising and fatalistic discourses, which inform resistance to diverse policy proposals (but especially those that are more 'upstream', macro-level proposals); and a lack of trust in (local and national) government. This suggests that efforts to enhance public support for evidence-informed policy responses to health inequalities may struggle unless these broader challenges are also addressed.

Long-term safety of triamcinolone acetonide nasal aerosol for the treatment of perennial allergic rhinitis.

A 1-year, open-label extension of a 12-week, double-blind clinical trial was conducted to evaluate the long-term safety and efficacy of once-daily therapy with triamcinolone acetonide nasal aerosol (110, 220, or 440 micrograms) in 93 patients with perennial allergic rhinitis. All three doses of triamcinolone acetonide were associated with sustained improvement in allergic rhinitis symptoms over the course of 1 year, as evidenced by physicians' and patients' global evaluations, ratings of the nasal environment (appearance and color of the nasal mucosa, as well as the quality of nasal secretions), nasal eosinophil counts, and requirement for escape medication. Among patients who reported adverse clinical experiences, most were considered unrelated or remotely related to therapy. Few patients experienced nasal irritation or throat discomfort, and no serious adverse experiences were attributed to treatment. Among 6 patients who withdrew from the study because of adverse experiences, a possible drug relationship was cited in 2 individuals (1 with headache and 1 with nasal blood) and a remote relationship in 1 (with acne). No clinically meaningful changes in vital signs, physical examinations, or laboratory values were noted, and mean serum cortisol levels were not suppressed during long-term treatment. These findings demonstrate that both safety and efficacy are maintained during long-term once-daily therapy with triamcinolone acetonide nasal aerosol in patients with perennial allergic rhinitis.

Splenectomy for hematologic disorders: a 20 year experience.

A retrospective chart analysis was conducted for all patients undergoing splenectomy for hematologic disorders at the Baptist Hospitals of Louisville between 1970 and 1989. Fifty-nine charts comprise the basis of this review. Variables considered included disease entities treated by splenectomy, indications for splenectomy, and morbidity and mortality associated with the surgery. Additional variables evaluated were splenic weight, estimated blood loss at surgery, technique of splenectomy, and drainage of the splenic bed. The authors found a high correlation of splenic weight to the hematologic disorder treated. Larger spleens were associated with greater blood loss at surgery. Preliminary splenic artery ligation did not reduce the operative blood loss in patients with massive spleens. Drainage of the splenic bed was not associated with postoperative bleeding or intra-abdominal abscess. The low morbidity (22%) and mortality (3.4%) compares favorably to other published studies, demonstrating that splenectomy for hematologic disorders may be safely performed in the community hospital setting.

Fluticasone propionate: an effective alternative treatment for seasonal allergic rhinitis in adults and adolescents.

BACKGROUND: Topical corticosteroids are widely regarded as the reference standard in allergic rhinitis therapy because they are well tolerated and effective against all rhinitis symptoms. We evaluated the efficacy, onset of action, and safety of two dosing regimens of the new corticosteroid fluticasone propionate compared with that of beclomethasone dipropionate in patients with moderate to severe seasonal allergic rhinitis. METHODS: In this double-blind, randomized multicenter trial, 110 adolescents and 128 adults were treated for 4 weeks with one of the following regimens: fluticasone aqueous nasal spray 100 micrograms twice daily or 200 micrograms once daily, beclomethasone aqueous nasal spray 168 micrograms twice daily, or placebo. RESULTS: Patient-rated scores for nasal obstruction, rhinorrhea, and combined nasal symptoms indicated that the two fluticasone regimens were equally effective and that both were superior to beclomethasone during most of the study (P < or = .05) and to placebo throughout the study (P < or = .01). Both fluticasone regimens also demonstrated significant clinical efficacy by 24 hours after the first dose. Clinician-rated mean total nasal symptoms scores for all three active treatments were superior to placebo at most time points but were not significantly different from each other. All treatments were well tolerated, with similar incidence and type of adverse events in all treatment groups and no apparent effects on hypothalamic-pituitary-adrenal (HPA) axis function. CONCLUSIONS: Fluticasone aqueous nasal spray was effective in relieving nasal symptoms in adolescents and adults with seasonal allergic rhinitis. Fluticasone administered once or twice daily was superior to beclomethasone administered twice daily in relieving nasal obstruction and rhinorrhea and in reducing nasal symptoms more quickly.

Damage threshold prediction of hafnia-silica multilayer coatings by nondestructive evaluation of fluence-limiting defects.

A variety of microscopic techniques were employed to characterize fluence-limiting defects in hafnia-silica multilayer coatings manufactured for the National Ignition Facility, a fusion laser with a wavelength of 1.053 mum and a pulse width of 3 ns. Photothermal microscopy, with the surface thermal lens effect, was used to map the absorption and thermal characteristics of 3 mm x 3 mm areas of the coatings. High-resolution subaperture scans, with a 1-mum step size and a 3-mum pump-beam diameter, were conducted on the defects to characterize their photothermal properties. Optical and atomic force microscopy were used to identify defects and characterize their topography. The defects were then irradiated by a damage testing laser (1.06 mum and 3 ns) in single-shot mode until damage occurred. The results were analyzed to determine the role of nodular and nonnodular defects in limiting the damage thresholds of the multilayer coatings. It was found that, although different types of defect were present in these coatings, the fluence-limiting ones had the highest photothermal signals (up to 126x over the host coating). The implication of this study is that coating process improvements for hafnia-silica multilayer coatings should have a broader focus than just elimination of source ejection, since high photothermal signals frequently occur at nodule-free regions. The study also demonstrates that, for optics subject to absorption-induced thermal damage, photothermal microscopy is an appropriate tool for nondestructive identification of fluence-limiting defects.

Obesity: an important prognostic factor in acute pancreatitis.

Ninety-nine patients with acute pancreatitis in whom body mass index (BMI = weight (kg)/height2 (m2)) was measured were studied prospectively to determine the importance of obesity as a prognostic factor in this disease. Of 19 obese patients (BMI > or = 30 kg/m2), 12 developed severe pancreatitis; seven had abscesses, of whom five died, and two further patients died. In 80 non-obese patients, the incidence of severe pancreatitis (n = 5), abscess formation (n = 4) and death (n = 4) was significantly less (P = 0.0007). The mean(s.d.) BMI of 17 patients with severe acute pancreatitis was significantly higher than that in 82 patients with mild acute disease (31.2(5.6) versus 23.3(5.6) kg/m2, P < 0.001). As a single prognostic factor, obesity had a sensitivity of 63 per cent and a specificity of 95 per cent for predicting disease severity. When five obese women with gallstone pancreatitis were excluded, the sensitivity of obesity increased to 86 per cent. Severe pancreatitis occurred in all eight obese patients with disease of an alcoholic aetiology. These data suggest that increased fat deposits in the peripancreatic and retroperitoneal spaces in obese patients may increase the risk of peripancreatic fat necrosis, abscess and death. Consideration should be given to including obesity as a prognostic factor in acute pancreatitis.

Selective accumulation of the first component of complement and leukocytes in ischemic canine heart muscle. A possible initiator of an extra myocardial mechanism of ischemic injury.

Myocardial concentrations of C1q, a subunit of the first component of complement, were measured 5-120 minutes after ligation of a coronary artery in dogs injected with 125I-labeled human C1q and 131I-labeled human albumin. The 131I-labeled human serum albumin was used as a plasma protein marker. Ischemic regions of myocardium were defined by measuring regional myocardial blood flow by the reference sample method at intervals after coronary artery occlusion. Significant accumulations of 125I-C1q were demonstrated in the ischemic myocardium after coronary artery occlusions lasting 45 minutes. Some localization of C1q in ischemic myocardium was observed after a 15-minute occlusion, but the accumulations of C1q achieved in this case were not statistically significant. After coronary artery occlusions lasting greater than or equal to 45 minutes, left ventricular concentrations of C1q correlated reciprocally with regional myocardial blood flow. Moreover, high concentrations of C1q persisted in formerly ischemic segments after reperfusion. Radiolabeled neutrophils also accumulated selectively in ischemic segments relatively rich in C1q. It is suggested that complement activation may initiate the neutrophil-dependent portion of ischemic injury, delineated in recent years, that is associated with free radical release by phagocytic cells.

Multicenter, double-blind, placebo-controlled trial of triamcinolone acetonide nasal aerosol in the treatment of perennial allergic rhinitis.

In a double-blind study involving 205 patients with perennial allergic rhinitis, statistically significantly greater symptomatic improvements were evident following the administration of 200 micrograms/day triamcinolone acetonide aerosol than following placebo. These improvements were evident as early as week 1 and were sustained throughout the 12-week study. They were accompanied by greater reductions in nasal eosinophils. Triamcinolone acetonide aerosol was well tolerated and had no effect on serum cortisol levels.

Once daily triamcinolone acetonide nasal spray is effective for the treatment of perennial allergic rhinitis.

A randomized, double-blind, placebo-controlled, parallel group study was conducted in 11 centers to evaluate the safety and efficacy of a once-a-day regimen of 110 micrograms, 220 micrograms; and 440 micrograms of triamcinolone acetonide intranasal aerosol versus placebo in relieving the symptoms of rhinitis in 305 adult and older pediatric patients with perennial allergic rhinitis. Nasal stuffiness, nasal discharge, sneezing, nasal itching and the nasal index (the sum of the mean scores of the first three symptoms) averaged over the first 6 weeks and second 6 weeks of the study were significantly reduced in patients who received the 220 micrograms/day and the 440 micrograms/day dosages. The 110 micrograms/day group had a reduction in these nasal symptoms, but only the sneezing and nasal index were significantly (P less than .05) better than placebo. During the last 6 weeks of the study, patients were allowed to take oral back-up medication for their nasal symptoms; all three groups receiving triamcinolone nasal aerosol took less back-up medication than did the placebo group. There were no significant adverse effects or laboratory abnormalities noted during this study. Intranasal triamcinolone acetonide 220 micrograms and 440 micrograms, used once-a-day for 12 weeks is clinically and statistically superior to placebo for the treatment of perennial allergic rhinitis.

Mechanism of complement activation after coronary artery occlusion: evidence that myocardial ischemia in dogs causes release of constituents of myocardial subcellular origin that complex with human C1q in vivo.

To evaluate whether ischemic myocardium releases molecules that react with the first component of complement, we studied cardiac lymph from eight dogs before and at intervals after coronary artery occlusion and reperfusion. Before occlusion, the dogs were injected intravenously with radiolabeled human C1q. Labeled C1q could be detected in the cardiac lymph within minutes following injection. Rabbit antisera, prepared against substances precipitated from postreprefusion cardiac lymph by anti-human C1q, also reacted with specific constituents of isolated cardiac sarcoplasmic reticulum and mitochondria. To evaluate whether mitochondria are the source of these C1q-binding proteins, we isolated intramyofibrillar and subsarcolemmal mitochondria from canine heart and incubated sonicates of these with purified C1q, immobilized on nitrocellulose. Molecules bound to the immobilized C1q were removed with 0.1% sodium dodecyl sulfate, fractionated under reducing conditions by polyacrylamide gel electrophoresis, and transferred electrophoretically to nitrocellulose paper. Antisera prepared against postreperfusion lymph reacted with a 31,000-32,000-dalton protein in these nitrocellulose paper replicas. Since this protein originates from mitochondria, binds to C1q, and is recognized by antibodies made against postreperfusion lymph, this protein is likely to be one of the subcellular constituents that, upon release from ischemic cells, activates the complement cascade. To evaluate the clinical relevance of these observations, we tested sera from 53 patients obtained 48-72 hours after hospitalization for suspected myocardial infarction.(ABSTRACT TRUNCATED AT 250 WORDS)

Fluticasone propionate aqueous nasal spray compared with terfenadine tablets in the treatment of seasonal allergic rhinitis.

BACKGROUND: Comparative studies with topical corticosteroids and antihistamines for treatment of allergic rhinitis have not always demonstrated clear distinctions between the two on the basis of therapeutic efficacy. OBJECTIVE: This study was designed to compare the efficacy and tolerability of fluticasone propionate aqueous nasal spray with those of terfenadine in the treatment of seasonal allergic rhinitis. METHODS: Three hundred forty-eight patients with allergic rhinitis were given fluticasone propionate aqueous nasal spray (200 micrograms once daily), terfenadine tablets (60 mg twice daily), or placebo for 4 weeks in a multicenter, randomized, double-blind, double-dummy, parallel-group study. RESULTS: Clinician-rated total nasal symptom scores after 1, 2, 3, and 4 weeks of therapy and patient-rated total nasal symptom scores throughout treatment were significantly (p <0.05) lower in the fluticasone propionate group compared with the terfenadine group or the placebo group. Terfenadine was not statistically different from placebo on the basis of clinician-related nasal symptom scores, except for sneezing. Total nasal airflow, measured by rhinomanometry, significantly (p <0.05) improved in the fluticasone propionate group compared with the terfenadine group or the placebo group. More fluticasone propionate-treated patients compared with placebo-treated patients had reduced nasal mucosal eosinophil counts after 4 weeks of therapy (p <0.05). No serious or unusual drug-related adverse events were reported. Morning plasma cortisol concentrations after 4 weeks of therapy did not differ among groups. CONCLUSION: Fluticasone propionate aqueous nasal spray is more effective than terfenadine tablets for treatment of seasonal allergic rhinitis.
