Background  

Few studies have explored exercise and motivational patterns of cardiac rehabilitation patients in the long term.     

Effect of volume of porogens on the porosity of PLGA scaffolds in pH-controlled environment

Poly(lactic-co-glycolic acid) (PLGA) is a well-studied biodegradable polymer used in drug delivery and other medical applications such as in tissue regeneration. It is often necessary to impart porosity within the scaffold (microparticles) in order to promote the growth of tissue during the regeneration process. Sodium chloride and ammonium bicarbonate have been extensively used as porogens in the generation of porous microstructure. In this study, we compared the effect of volumes (250?μl, 500?μl and 750?μl) of two porogens, sodium chloride (1.71 M) and ammonium bicarbonate (1.71 M), on the porosity of PLGA microparticles.     

The meaning and consequences of tuberculosis among Somali people in the United Kingdom

Aim. To ascertain the socio‐cultural meaning and consequences of tuberculosis among people of Somali origin living in the UK. Background. In countries where treatment has not been readily available, tuberculosis has become highly stigmatized. Research in Somalia has documented the stigma and social isolation associated with tuberculosis which acts as a powerful deterrent to sufferers acknowledging their illness. The Somali community in the UK is diverse and dynamic: little is known about how tuberculosis is understood, or how stigma is articulated and experienced post‐migration. Design. A focused ethnography was undertaken. Method. A total of 48 individual interviews were undertaken in 2008–2009 with community leaders, Somali community members and tuberculosis patients to explore the social meaning of tuberculosis and perceived consequences of the disease. Eight focus groups were undertaken involving 56 participants. Vignettes concerning tuberculosis were used to prompt discussion of community norms and socio‐cultural constructions of tuberculosis. Data were analysed using the ‘Framework’ approach. Findings. Most participants were familiar with tuberculosis, its characteristics and treatment. However, many participants held misconceptions about how the disease spread and its prognosis. Tuberculosis was perceived as a stigmatizing disease. Somalis with tuberculosis were considered likely to experience felt and enacted stigma with fear of discrimination in the form of social isolation influencing the extent to which people with tuberculosis disclosed their condition. Conclusion. Nurses should understand the socio‐cultural meaning and consequences of tuberculosis for Somalis to educate the community through public health initiatives and support patients and their families.     

Improving recognition of delirium in clinical practice: a call for action

ABSTRACT: BACKGROUND: The purpose of this correspondence article is to report opinion amongst experts in the delirium field as to why, despite on-going training for all health professionals, delirium continues to be under recognised. Consensus was obtained by means of two conference workshops and an online survey of members of the European Delirium Association.Major barriers to recognition at an individual level include ignorance about the benefit of treating delirium. At an organisational level, reflecting socio-cultural attitudes, barriers include a low strategic and financial priority and the fact that delirium is an orphan condition falling between specialties.     

Rituximab in the treatment of systemic sclerosis-associated interstitial lung disease: Comment on the article by Yoo

Several lines of evidence from basic research indicate that B cells may contribute to the pathogenesis of systemic sclerosis. Clinical studies as well have provided preliminary data pointing to the direction that B-cell depletion with rituximab might be a therapeutic option for patients with this debilitating disease.
