Use of Japanese Encephalitis Vaccine in US Travel Medicine Practices in Global TravEpiNet

Few data regarding the use of Japanese encephalitis (JE) vaccine in clinical practice are available. We identified 711 travelers at higher risk and 7,578 travelers at lower risk for JE who were seen at US Global TravEpiNet sites from September of 2009 to August of 2012. Higher-risk travelers were younger than lower-risk travelers (median age = 29 years versus 40 years, P < 0.001). Over 70% of higher-risk travelers neither received JE vaccine during the clinic visit nor had been previously vaccinated. In the majority of these instances, clinicians determined that the JE vaccine was not indicated for the higher-risk traveler, which contradicts current recommendations of the Advisory Committee on Immunization Practices. Better understanding is needed of the clinical decision-making regarding JE vaccine in US travel medicine practices.     

Earlier intervention in type 2 diabetes: the case for achieving early and sustained glycaemic control

In type 2 diabetes, the onset and progression of complications is significantly delayed by improving glycaemic control. However, the proportion of patients reaching and sustaining guideline recommendations for glycaemic targets remains unacceptably low. Recent clinical trials and predictive physiologically based mathematical simulations (Archimedes model) indicate that benefits can be enhanced with earlier intervention and timely achievement of glycaemic targets. This article reviews the evidence for early intervention, showing that intensive approaches, including earlier introduction of combination therapy, allow more patients to achieve glycaemic targets and hence reduce complications and delay disease progression.     

Promoting the Value of Mental Health Nursing: The Contribution of a Consumer Academic

Mental illness is known to occur frequently in the general population and is more common within the general health care system. High-quality health care requires nurses to have the skills, knowledge and attitudes to provide care for people experiencing mental illness or mental distress. Research suggests health professionals, including nurses, tend to share similar negative attitudes to mental illness as the general population, and consequently, mental health nursing is not a popular career path. These two factors signify a need to influence more positive attitudes toward mental illness and mental health nursing among nursing students. A qualitative exploratory research study was undertaken to examine the experiences, opinions and attitudes of an academic and research team to the introduction of a consumer academic within an undergraduate mental health nursing subject. In-depth interviews were conducted with teaching and research team members. The importance of mental health skills emerged as a major theme and included sub-themes: mental health across the health care system; contribution of consumer academic to nursing skills; addressing fear and stigma, and inspiring passion in mental health nursing. Findings suggest academic input from people with lived experience of recovery from mental illness can influence the development of mental health nursing skills and enhance the popularity of mental health nursing as a career.     

A multinational comparison of racecadotril and loperamide in the treatment of acute watery diarrhoea in adults

BACKGROUND: Racecadotril (acetorphan) is an orally active, potent inhibitor of enkephalinase, which exerts an antihypersecretory effect without increasing intestinal transit time. The aim of this study was to compare the efficacy, safety and tolerability of racecadotril with those of loperamide by assessing their effects on the resolution of the signs and symptoms of diarrhoea in patients in developing countries who had acute watery diarrhoea of less than 5 days' duration. METHODS: 945 outpatients from 21 centres in 14 countries received racecadotril (100 mg) or loperamide (2 mg) three times daily in a single-blind study. Duration of diarrhoea was the primary measure of efficacy; secondary criteria were overall clinical response, occurrence and duration of abdominal pain and distension, and occurrence of other associated signs and symptoms. Occurrence of constipation and adverse events were the main safety assessments. RESULTS: Diarrhoea resolved rapidly with both racecadotril and loperamide (55.0 h in both groups), 92% of patients on racecadotril and 93% on loperamide being treatment successes. Racecadotril produced a significantly greater reduction in abdominal pain and distension than loperamide (P = 0.024 and 0.03, respectively). The duration of abdominal distension was significantly shorter with racecadotril (5.4 versus 24.4 h; P = 0.0001), and constipation was also significantly less frequent (16% versus 25%; P = 0.001). One-hundred-and-eighty patients (19%) experienced one or more adverse event during the study: 67 (14.2%) in the racecadotril group and 113 (23.9%) in the loperamide group (P = 0.001). CONCLUSIONS: Racecadotril resolved the symptoms of acute diarrhoea rapidly and effectively, and produced more rapid resolution of abdominal symptoms and less constipation than loperamide.     

A multicomponent strategy to improve the availability of antivenom for treating snakebite envenoming

Snakebite envenoming is a common but neglected public health problem, particularly in impoverished rural regions of sub-Saharan Africa, Asia and Latin America. The only validated treatment for this condition is passive immunotherapy with safe and effective animal-derived antivenoms. However, there is a long-lasting crisis in the availability of these life-saving medications, particularly in sub-Saharan Africa and parts of Asia. We herein advocate a multicomponent strategy to substantially improve the availability of safe and effective antivenoms at the global level. This strategy is based on: (i) preparing validated collections of representative venom pools from the most medically dangerous snakes in high-risk regions of the world; (ii) strengthening the capacity of national antivenom manufacturing and quality control laboratories and their regulatory authorities and establishing new facilities in developing countries through technology transfer, as an integral part of efforts to develop their biological products industry; (iii) getting established laboratories to generate antivenoms for various regions of the world; and (iv) getting governments and relevant organizations to give snakebite envenoming due recognition within national and international public health policy frameworks. These ways of making antivenom available should be complemented by actions to improve health information systems, the accessibility of antivenoms, the training of medical and nursing staff, and community-based education. Such a multicomponent strategy involving stakeholders on many levels could help consolidate sustainable improvements in antivenom availability worldwide.
