Prevention of Cataract Blindness in Rural China.

China has undergone dramatic economic and social reforms during last 30 years, leading to a notably higher level of living standards and health care access for Chinese citizens. However, China's cataract surgical rate of 780 cases/y per million population trails Asian neighbors with lower income levels such as India and Vietnam. Eye care providers and patients encounter many barriers in gaining access to one another.Hands-on training programs conducted by international nongovernmental organizations and the government have helped to increase the number of qualified cataract surgeons in rural area, but establishing a residency training system that produces ophthalmologists capable of performing independent surgery is the only sustainable way to meet the increasing demand for surgery from an aging population. The New Rural Cooperative Medical System has successfully reduced the financial burden of cataract surgery for the rural population; however, reimbursement for outpatient treatment of leading eye diseases is needed.Community outreach screening combined with education is essential in rural areas' increased demand for surgery. Methods to optimize the yield from such screening must still be devised and proven, however. Improvements in the hospital administration and management structure are also needed to improve the efficiency of China's rural hospitals in delivering high-quality, low-cost cataract surgical services.

The challenge of MNCs and development: oil extraction, CSR, Nigeria and corruption

Globalisation has led to a shift in world order with the rise of the corporate non-state actor. This rise has led to an assumption that Multi-National Corporations (MNCs) must assume responsibilities beyond profit maximisation for shareholders. With the rise of the MNC as a corporate non-state actor there have been discussions around the role of business with regard to human rights.

This article looks at the case of oil extraction in Nigeria. Focussing on the historical dependency of Nigeria and the evolution of the state into a resource-dependent country, it looks at the limitations of existing human rights obligations as they relate to business. This article proposes that corporate social responsibility (CSR) policies of MNCs can act as a preliminary stage in the quest for wider human rights protections. It is in motivating MNCs to design and implement effective CSR policies in dependent states like Nigeria, that the challenge lies.

A Reappraisal of the Safety and Cost-Effectiveness of Statin Therapy in Primary Prevention

Statins are among the most investigated drugs of all time. There is now a wealth of evidence supporting their use in the primary and secondary prevention arenas. The reduction in event recurrence has since been demonstrated across all levels of risk and in elderly patients. As a result, it is now accepted practice for statins to be prescribed universally in secondary prevention unless contraindicated. The extension of this policy into the primary prevention setting is more problematic, with moral and financial issues arising from the long-term treatment of many young apparently healthy individuals. For these reasons it is necessary to prove not only the financial sustainability of such a strategy but also the long-term safety of statins and the degree of benefit that might be expected.

Impact of non-pharmacological interventions on prevention and treatment of delirium in critically ill patients: protocol for a systematic review of quantitative and qualitative research

Background: Critically ill patients have an increased risk of developing delirium during their intensive care stay.To date, pharmacological interventions have not been shown to be effective for delirium management but non-pharmacological interventions have shown some promise. The aim of this systematic review is to identify effective non-pharmacological interventions for reducing the incidence or the duration of delirium in critically ill patients.

Methods: We will search MEDLINE, EMBASE, CINAHL, Web of Science, AMED, psycINFO and the Cochrane Library.We will include studies of critically ill adults and children. We will include randomised trials and controlled trials which measure the effectiveness of one or more non-pharmacological interventions in reducing incidence or duration ofdelirium in critically ill patients. We will also include qualitative studies that provide an insight into patients and their families’ experiences of delirium and non-pharmacological interventions. Two independent reviewers will assess studies for eligibility, extract data and appraise quality. We will conduct meta-analyses if possible or present results narratively.Qualitative studies will also be reviewed by two independent reviewers, and a specially designed quality assessment tool incorporating the CASP framework and the POPAY framework will be used to assess quality.

Discussion: Although non-pharmacological interventions have been studied in populations outside of intensive care units and multicomponent interventions have successfully reduced incidence and duration of delirium, no systematic review of non-pharmacological interventions specifically targeting delirium in critically ill patients have been undertaken to date. This systematic review will provide evidence for the development of a multicomponent intervention for delirium management of critically ill patients that can be tested in a subsequent multicentre randomised trial.

Retinopathy of prematurity: Causes, prevention and treatment

Advances in neonatal intensive care have improved survival rates in extremely premature an infant, which has led to an increase of Retinopathy of Prematurity (ROP) in the developed world. Left untreated, infants are at risk of developing strabismus, myopia, vitreous haemorrhage, vitreo-retinal fibrosis, retinal detachment, secondary angle closure glaucoma and ultimately complete loss of vision. The improvements in the understanding and treatment of ROP have been supported by seminal research, and its complexity is still being explored. However the importance of early screening and treatment is essential in the prevention and treatment of this disease. The following paper will examine the causes and treatments of ROP, as well as implications for future neonatal practice.
