'Think differently and be prepared to demonstrate trust': findings from public hearings, England, on supporting lay people in public health roles

Professional support processes are critical for the establishment and maintenance of community health worker programmes. This paper reports on three public hearings held in England, UK, that were conducted as part of a national study into approaches to develop and support lay people in public health roles. Individuals with relevant theoretical or practical expertise, including lay activists, presented evidence in public as expert witnesses. Formal presentations, questions and plenary discussions were recorded and later analysed as qualitative data. This paper presents the results and critically examines emergent issues relating to the sustainability of lay health worker programmes. Consideration is given to the diversity of contemporary practice in England. Barriers seen to affect sustainability included organizational culture and onerous bureaucratic processes. Major themes emerging from the expert evidence included recruitment and training strategies, financial support and the need for a robust infrastructure. The expert hearings, in creating a public space for deliberation, opened up discussion on the levels and type of programme support required to foster lay health worker programmes. The paper concludes that professional support needs to be accompanied by a reorientation of public services to support lay engagement in programme delivery.     

Relative corticosteroid insensitivity of peripheral blood mononuclear cells in severe asthma

RATIONALE AND OBJECTIVES: Patients with severe asthma have a poor therapeutic response to corticosteroid therapy, and corticosteroid responsiveness cannot be easily measured in these patients. We hypothesized that this poor response is associated with a reduced effect of corticosteroids to inhibit cytokine release from activated peripheral blood mononuclear cells (PBMCs). METHODS: Patients with severe asthma were defined by American Thoracic Society criteria. We compared the suppression of LPS-induced cytokine release (monocyte chemotactic protein-1 [MCP-1], macrophage inflammatory protein [MIP] 1alpha, RANTES, tumor necrosis factor alpha, interleukin 1beta (IL-1beta), IL-8, IFN-gamma, IL-6, IL-10, and granulocyte-macrophage colony-stimulating factor [GM-CSF]) by dexamethasone from PBMCs of patients with severe asthma (n = 16), patients with nonsevere asthma (n = 19), and normal volunteers (n = 10). RESULTS: There was no difference in baseline spontaneous or stimulated release of these cytokines among groups. LPS-induced release of 10 cytokines was less suppressed by dexamethasone (10(-6) M) in patients with severe asthma compared with patients with nonsevere asthma, with statistical significance achieved for IL-1beta (p < 0.03), IL-8 (p < 0.03), and MIP-1alpha (p < 0.003), and borderline significance for IL-6 (p = 0.054). There was less difference between the two groups for dexamethasone at 10(-8) M. Nuclear histone deacetylase (HDAC) and histone acetyltransferase activities were reduced in patients with severe asthma compared with patients with nonsevere asthma (p < 0.01). HDAC activity reduction correlated directly to the degree of steroid insensitivity of GM-CSF (r = 0.57, p < 0.01) and IFN-gamma (r = 0.56, p < 0.05) release. Reduction in histone acetyltransferase activity related to corticosteroid use rather than asthma severity. CONCLUSIONS: Patients with severe asthma have diminished corticosteroid sensitivity of PBMCs when compared with patients with nonsevere asthma, associated with a reduction in HDAC activity that parallels the impaired corticosteroid sensitivity.     

Still blaming the consumer? Geographies of responsibility in domestic food safety practices

Drawing upon qualitative and ethnographic data collected in the UK, this paper discusses how public discourses and concerns about food safety are negotiated into everyday domestic kitchen practices. While many participants demonstrated ‘behaviours’ or ‘practices’ which could be seen to contravene or fall short of official guidelines, this does not necessarily indicate ‘ignorance’ or lack of responsibility on the part of consumers. Indeed, when explored in detail, participants presented a range of reasons for engaging in what the UK Food Standards Agency regard as ‘risky’ practices. Their explanations point toward an understanding of the distribution of domestic responsibility in which a number of stakeholders are implicated, while simultaneously acknowledging their role as final arbiters of food safety in the home.     

Isolated perforations of the ileum and jejunum in blunt abdominal trauma.

A report of ten cases of perforations of the ileum and jejunum from blunt abdominal trauma is presented. The perforation was the only injury in eight patients, while in two there were other visceral injuries. The perforations were single in seven patients and double in three. Simple closure was used in seven cases and resection in three. Of the three patients who were operated upon late, one died.     

Reproducibility of quantitative plaque measurement in advanced coronary artery disease

BackgroundThe ability to characterize and to quantify the extent of coronary artery disease has the potential to improve the prognostic capability of coronary computed tomography angiography. Although reproducible techniques have been described in those with mild coronary disease, this has yet to be assessed in patients with advanced disease.MethodsTwenty patients with known multivessel disease underwent repeated computed tomography coronary angiography, 2 weeks apart. Coronary artery segments were analysed using semi-automated software by two trained observers to determine intraobserver, interobserver and interscan reproducibility.ResultsOverall, 149 coronary arterial segments were analysed. There was excellent intraobserver and interobserver agreement for all plaque volume measurements (Lin’s coefficient 0.95 to 1.0). There were no substantial interscan differences (P ?> ?0.05 for all) for total (2063 ?± ?1246 ?mm³, mean of differences ?35.6 ?mm³), non-calcified (1795 ?± ?910 ?mm³, mean of differences ?4.3 ?mm³), calcified (298 ?± ?425 ?mm³, mean of differences ?31.3 ?mm³) and low-attenuation (13 ?± ?13 ?mm³, mean of differences ?2.6 ?mm³) plaque volumes. Interscan agreement was highest for total and noncalcified plaque volumes. Calcified and low-attenuation plaque (?236.6 to 174 ?mm³ and -15.8 to 10.5 ?mm³ respectively) had relatively wider 95% limits of agreement reflecting the lower absolute plaque volumes.ConclusionIn the presence of advanced coronary disease, semi-automated plaque quantification provides excellent reproducibility, particularly for total and non-calcified plaque volumes. This approach has major potential to assess change in disease over time and optimize risk stratification in patients with established coronary artery disease.     

Recalcitrant lichen planopilaris and frontal fibrosing alopecia responding to tildrakizumab

Lichen planopilaris (LPP) and frontal fibrosing alopecia (FFA) are lymphocytic, cicatricial alopecias. Clinically, LPP presents with multifocal patchy alopecia, while FFA, considered a variant of LPP, results in hairline recession. Frontal recession in FFA may progress as far as the mid‐scalp and infrequently beyond. Treatment to arrest the inflammatory process can be challenging and response variable. We report a case of recalcitrant lichen planopilaris and frontal fibrosing alopecia demonstrating significant clinical improvement after four doses of the interleukin‐23 monoclonal antibody tildrakizumab.     

A review of the treatment of male pattern hair loss

ABSTRACT

Introduction

Androgenetic alopecia is a common hair loss disorder affecting up to 80% of males by the age of 80. It is characterized by androgen related progressive thinning of hair in a defined pattern. It results in diminished self-esteem, reduced confidence and distress in affected men, irrespective of age or stage of baldness. An effective treatment for hair baldness is needed.
