Ever since the 2006 World Health Report advocated increased community participation and the systematic delegation of tasks to less-specialized cadres, there has been a great deal of debate about the expediency, efficacy and modalities of task shifting. The delegation of tasks from one cadre to another, previously often called substitution, is not a new concept. It has been used in many countries and for many decades, either as a response to emergency needs or as a method to provide adequate care at primary and secondary levels, especially in understaffed rural facilities, to enhance quality and reduce costs. ⋯ Most importantly, task shifting strategies require leadership from national governments to ensure an enabling regulatory framework; drive the implementation of relevant policies; guide and support training institutions and ensure adequate resources; and harness the support of the multiple stakeholders. With such leadership and a willingness to learn from those with relevant experience (for example, Brazil, Ethiopia, Malawi, Mozambique and Zambia), task shifting can indeed make a vital contribution to building sustainable, cost-effective and equitable health care systems. Without it, task shifting runs the risk of being yet another unsuccessful health sector reform initiative.

Internationally there is commitment to work towards eradicating the abuse of older people and to develop services that promote their equality, dignity and human rights. The emphasis on service users is gradually increasing and, along with this, the focus within health and social care policy, service provision and professional practice is shifting. In UK health and social care policy the emphasis on service structure and provision is being replaced by a focus on outcomes for service users, including outcomes which patients themselves evaluate. ⋯ The outcomes framework developed through the research is offered, along with a discussion of the advantages of an outcome-focused approach to care and some of the remaining challenges. A case example is offered to illustrate an outcomes-focused approach. Finally, the paper draws conclusions on how shifting the focus of care delivery from traditional problem-orientated approaches and ritualized practice towards the outcomes of care that individual older people choose and evaluate for themselves offers potential towards eradicating abuse and neglect in formal care settings.

Bilateral lemierre syndrome secondary to periodontitis: a case report and review of the literature.
Lemierre syndrome is the typical presentation of human necrobacillosis. It is characterized by an initial infection, progressing to septic thrombophlebitis, septicemia, and multisystem embolic necrotic abscesses. It is usually caused by Fusobacterium necrophorum, but its pathophysiology remains obscure. A case of bilateral Lemierre syndrome secondary to periodontitis is reported. ⋯ A case is reported of extensive bilateral septic thrombophlebitis of the deep neck veins secondary to periodontal disease. To the best of my knowledge, this is the first case of bilateral Lemierre syndrome due to periodontal disease reported in the literature. It highlights the typical septic thrombophlebitis of Lemierre syndrome and its protean manifestations, such as hepatitis and rhabdomyolysis. This presentation also underscores the significance of thorough dental examinations in febrile patients. With respect to anticoagulation therapy in Lemierre syndrome, though still not established, there is some evidence of utility with no untoward effects.

Activated protein C in the treatment of acute lung injury and acute respiratory distress syndrome.
Acute lung injury (ALI) and acute respiratory distress syndrome (ARDS) frequently necessitate mechanical ventilation in the intensive care unit. The syndromes have a high mortality rate and there is at present no treatment specifically directed at the underlying pathogenesis. Central in the pathophysiology of ALI/ARDS is alveolocapillary inflammation leading to permeability edema. As a result of the crosstalk between inflammation and coagulation, activation of proinflammatory and procoagulant/antifibrinolytic pathways contributes to disruption of the endothelial barrier. Protein C (PC) plays a central role in maintaining the equilibrium between coagulation and inflammation. Additionally, natural anticoagulants, such as PC, are depleted, both in blood as well as in the lung. Therefore, the PC system is of interest as a therapeutic target in patients with ALI/ARDS. ⋯ It discusses the potential role of activated PC in modulating the proinflammatory/procoagulant state for enhancing endothelial barrier function in animal models and human ALI/ARDS.

While wound contraction plays an important role in healing, it may lead to excessive scar formation and pathological wound contracture in extreme conditions. To date, the key regulator of wound contraction and keloid formation is transforming growth factor-beta (TGF-b1). Decorin has been reported to bind TGF-b1 and neutralize some of its activities. ⋯ These data indicate that recombinant human decorin can suppress TGF-b1-induced contraction of collagen gel by keloid fibroblasts. Moreover, decorin can inhibit basal contraction of collagen gel by keloid fibroblasts. These results suggest that decorin may have therapeutic potential for excessive skin contraction as observed in a keloid. .
