RÉSUMÉ
Mangroves are considered ideal ecosystems for Blue Carbon projects. However, because of their short stature, some mangroves ('scrub' mangroves, less than 2 m) do not fulfil the current definition of 'forests', which makes them ineligible for emission reduction programmes such as REDD+. Short stature mangroves can be the dominant form of mangroves in arid and nutrient-poor landscapes, and emissions from their deforestation and degradation could be substantial. Here, we describe a Blue Carbon project in the Gulf of California, Mexico, to illustrate that projects that avoid emissions from deforestation and degradation could provide financial resources to protect mangroves that cannot be included in other emission reduction programmes. The goal of the project is to protect 16 058 ha of mangroves through conservation concessions from the Mexican Federal Government. The cumulative avoided emissions of the project are 2.84 million Mg CO2 over 100 years, valued at $US 426 000 per year (US$15 per Mg CO2 in the California market). The funds could be used for community-based projects that will improve mangrove management, such as surveillance, eradication of invasive species, rehabilitation after tropical storms and environmental education. The strong institutional support, secure financial status, community engagement and clear project boundaries provide favourable conditions to implement this Blue Carbon project. Financial resources from Blue Carbon projects, even in mangroves of short stature, can provide substantial resources to enhance community resilience and mangrove protection.

High levels of sHLA-I (soluble HLA--class I) have been correlated with rejection episodes in solid organ transplant recipients and with graft versus host disease in bone marrow recipients. Studies of human infection with parasitic worms of the gut have suggested that certain individuals may be genetically predisposed to intense infection. In this study, the influence of parasitic helminth infection on levels of sHLA-I in plasma was investigated in 155 HLA typed individuals from St. Lucia, exposed to the gut parasite Trichuris trichiura. The results confirmed previous findings showing increased levels of sHLA-I in HLA-A9, and in this case HLA-A23 positive individuals. However, HLA-A9 positive individuals with high worm burden had significantly lower levels of sHLA-I in their plasma compared with HLA-A9 positive subjects with low worm burden. These results suggest that the intensity of T. trichiura infection influences the ability of HLA-A9 positive subjects to maintain high levels of sHLA-I.

Many hospitals are considering enhanced approaches to patient satisfaction measurement and guest relations--or service management. Some are building in-house satisfaction management systems. Others are evaluating the growing number of systems commercially available for purchase. The authors review the successful design, testing, introduction, and nearly 5-year use of an in-house system.
