The World Health Organization (WHO) endorses the use of population-based prevalence surveys for estimating the prevalence of trachoma. In general, the prevalence of TF in children aged 1–9 years and the prevalence of TT in adults aged ≥ 15 years are measured at the same time in any district bein...g surveyed. This was the approach of the Global Trachoma Mapping Project, which undertook baseline surveys in > 1500 districts worldwide in order to provide the data required to start interventions where needed.
The survey design recommended by WHO is a two-stage cluster random sample survey, which uses probability proportional to size sampling to select 20–30 villages, and random, systematic or quasi-random sampling to select 25–30 households in each of those villages. In most surveys, everyone aged ≥ 1 year living in selected households is examined.

Surveys are needed to guide trachoma control efforts in Mozambique, with WHO guidelines for intervention based on the prevalence of trachomatous inflammation–follicular (TF) in children aged 1–9 years and the prevalence of trichiasis in adults aged 15 years and above. We conducted surveys to com...plete the map of trachoma prevalence in Mozambique, concluding that it still represents a significant public health problem in many areas of Mozambique.

Vitamin A supplementation (VAS) programs targeted at children aged 6–59 months are implemented in many countries. By improving immune function, vitamin A (VA) reduces mortality associated with measles, diarrhea, and other illnesses. There is currently a debate regarding the relevance of VAS, but a...midst the debate, researchers acknowledge that the majority of nationally-representative data on VA status is outdated. To address this data gap and contribute to the debate, we examined data from 82 countries implementing VAS programs, identified other VA programs, and assessed the recentness of national VA deficiency (VAD) data.

There are varying Christian perspectives on medical ethics, depending onthe differing beliefs, principles and practicesthat undergird them. Notonly are there numerous Christian churches and organisations but,within and between these, there are varying schools of thought that seek to ... guide theological and ethical enquiry. In addition, most Christian believers are encouraged to make their own personal ethical decisions. While biblical and theological reflection,especially on the life and teaching of Jesus, will play an important role in many individuals’ decision making, others will base their decisions more loosely on a mixture of their Christian ‘background’, their personal experience and their daily interaction with people and current ideas. It is not possible, therefore, to present a definitive Christian perspective on medical ethics, but it is possible to identify many of the features that contribute, consciously or, perhaps more often, subconsciously, to the perspectives that most Christians have.

En el Perú, la elaboración de guías de práctica clínica tiene exigencia normativa desde el año
2005; sin embargo, su desarrollo ha ténido poco énfasis en la calidad metodológica de las mismas, prefiriendo el tipo narrativo. Desde hace varios años se realiz...an esfuerzos dispersos para mejorar la calidad metodológica, principalmente que su elaboaración esté basada en evidencias científicas. Actualmente se cuenta con una nueva normativa que pone mayor enfasis en esta exigencia y algunas instituciones ya trabajan para adecuarse a estandares internacionales y poder generar impactos positivos en nuestro sistema de salud a través del adecuado desarrollo de guias de practica clínica en nuestro pais
