Thiopurines related malignancies in inflammatory bowel disease: Local experience in Granada, Spain.

AIM To investigate the incidence of neoplasms in inflammatory bowel disease (IBD) patients and the potential causative role of thiopurines. METHODS We performed an observational descriptive study comparing the incidence of malignancies in IBD patients treated with thiopurines and patients not treated with these drugs. We included 812 patients which were divided in two groups depending on whether they have received thiopurines or not. We have studied basal characteristics of both groups (age when the disease was diagnosed, sex, type of IBD, etc.) and treatments received (Azathioprine, mercaptopurine, infliximab, adalimumab or other immunomodulators), as well as neoplasms incidence. Univariate analysis was performed with the student t test, χ(2) test or Wilcoxon exact test as appropriate. A logistic regression analysis was performed as multivariate analysis. Statistical significance was establish at P values of less than 0.05, and 95%CI were used for the odds ratios. RESULTS Among 812 patients included, 429 (52.83%) have received thiopurines: 79.5% azathioprine, 14% mercaptopurine and 6.5% both drugs. 44.76% of patients treated with thiopurines and 46, 48% of patients who did not receive this treatment were women (P > 0.05). The proportion of ulcerative colitis patients treated with thiopurines was 30.3% compare to 66. 67% of patients not treated (P < 0.001). Mean azathioprine dose was 123.79 ± 36.5 mg/d (range: 50-250 mg/d), mean usage time was 72.16 ± 55.7 mo (range: 1-300 mo) and the accumulated dose along this time was 274.32 ± 233.5 g (1.5-1350 g). With respect to mercaptopurine, mean dose was 74.7 ± 23.9 mg/d (range: 25-150 mg/d), mean usage time of 23.37 ± 27.6 mo (range: 1-118 mo), and the accumulated dose along this time was 52.2 ± 63.5 g (range: 1.5-243 g). Thiopurine S-methyltransferase activity was tested in 66% of patients treated with thiopurines, among which 98.2% had an intermediate or high activity. Among the patients treated with thiopurines, 27.27% (112 patients) and 11.66% (50 patients) received treatment with Infliximab and Adalimumab respectively, but only 1.83% (7 patients) and 0.78% (3 patients) received these drugs in the group of patients who did not received thiopurines (P < 0.001 and P < 0.001 respectively). Finally, 6.8% (29 patients) among those treated with thiopurines have received other immunesupresants (Methotrexate, Tacrolimus, Cyclosporin), compare to 1% (4 patients) of patients not treated with thiopurines (P < 0.001). Among patients treated with thiopurines, 3.97% developed a malignancy, and among those not treated neoplasms presented in 8.1% (P = 0.013). The most frequent neoplasms were colorectal ones (12 cases in patients not treated with thiopurines but none in treated, P < 0.001) followed by non-melanoma skin cancer (8 patients in treated with thiopurines and 6 in not treated, P > 0.05). CONCLUSION In our experience, thiopurine therapy did not increase malignancies development in IBD patients, and was an efective and safe treatment for these diseases.

Endocarditis due to Tropheryma whipplei: rapid detection, limited genetic diversity, and long-term clinical outcome in a local experience

The characteristic features of Whipple's disease include abdominal pain, diarrhoea, wasting, and arthralgias, with the causative agent, Tropheryma whipplei, being detected mainly in intestinal biopsies. PCR technology has led to the identification of T. whipplei in specimens from various other locations, including the central nervous system and the heart. T. whipplei is now recognized as one of the causes of culture-negative endocarditis, and endocarditis can be the only manifestation of the infection with T. whipplei. Although it is considered a rare disease, the true incidence of endocarditis due to T. whipplei is not clearly established. With the increasing use of molecular methods, it is likely that T. whipplei will be more frequently identified. Questions also remain about the genetic variability of T. whipplei strains, optimal diagnostic procedures and therapeutic options. In the present study, we provide clinical data on four new patients with documented endocarditis due to T. whipplei in the context of the available published literature. There was no clinical involvement of the gastrointestinal tract. Genetic analysis of the T. whipplei strains with DNA isolated from the excised heart valves revealed little to no genetic variability. In a selected case, we describe acridine orange staining for early detection of the disease, prompting early adaptation of the antibiotic therapy. We provide long-term follow-up data on the patients. In our hands, an initial 2-week course of intravenous antibiotics followed by cotrimoxazole for at least 1 year was a suitable treatment option for T. whipplei endocarditis.

Gaslini's tracheal team: preliminary experience after one year of paediatric airway reconstructive surgery.

Background: congenital and acquired airway anomalies represent a relatively common albeit challenging problem in a national tertiary care hospital. In the past, most of these patients were sent to foreign Centres because of the lack of local experience in reconstructive surgery of the paediatric airway. In 2009, a dedicated team was established at our Institute. Gaslini's Tracheal Team includes different professionals, namely anaesthetists, intensive care specialists, neonatologists, pulmonologists, radiologists, and ENT, paediatric, and cardiovascular surgeons. The aim of this project was to provide these multidisciplinary patients, at any time, with intensive care, radiological investigations, diagnostic and operative endoscopy, reconstructive surgery, ECMO or cardiopulmonary bypass. Aim of this study is to present the results of the first year of airway reconstructive surgery activity of the Tracheal Team.Methods: between September 2009 and December 2010, 97 patients were evaluated or treated by our Gaslini Tracheal Team. Most of them were evaluated by both rigid and flexible endoscopy. In this study we included 8 patients who underwent reconstructive surgery of the airways. Four of them were referred to our centre or previously treated surgically or endoscopically without success in other Centres.Results: Eight patients required 9 surgical procedures on the airway: 4 cricotracheal resections, 2 laryngotracheoplasties, 1 tracheal resection, 1 repair of laryngeal cleft and 1 foreign body removal with cardiopulmonary bypass through anterior tracheal opening. Moreover, in 1 case secondary aortopexy was performed. All patients achieved finally good results, but two of them required two surgeries and most required endoscopic manoeuvres after surgery. The most complex cases were the ones who had already been previously treated.Conclusions: The treatment of paediatric airway anomalies requires a dedicated multidisciplinary approach and a single tertiary care Centre providing rapid access to endoscopic and surgical manoeuvres on upper and lower airways and the possibility to start immediately cardiopulmonary bypass or ECMO.The preliminary experience of the Tracheal Team shows that good results can be obtained with this multidisciplinary approach in the treatment of complicated cases. The centralization of all the cases in one or few national Centres should be considered.

Closing the gap: Setting local targets to reduce health inequalities

This briefing paper provides a summary of the policies, theory and practice of setting targets to reduce health inequalities. It offers some guidance for those responsible for setting local targets and sets this in the context of local experience drawn from documentary evidence from health improvement programmes (HImPs), community strategies and health action zones (HAZs).

Treatment of pediatric myelodysplastic syndromes and juvenile myelomonocytic leukemia: the Brazilian experience in the past decade

Background: Therapy strategies for myelodysplastic syndromes (MDS) and juvenile myelomonocytic leukemia (JMML) vary considerably. Objective: To review the treatment of Brazilian children who were diagnosed with MDS or JMML in the past decade and reported to the Brazilian Cooperative Group on Pediatric Myelodysplastic syndromes (BCG-MDS-PED). Results: of 173 children reported to the BCG-MDS-PED from January 1997 to January 2003 with a suspected diagnosis of MDS or JMML, 91 had the diagnosis confirmed after central review of the bone marrow aspirate and biopsy. Information on previous treatments was available for 78 MDS/JMML patients. Treatment varied from different schedules of low-dose (14%) and standard-dose chemotherapy (50%), granulocyte-colony-stimulating factor (G-CSF 7%), interferon (5%), steroids (2%) and erythropoietin (2%) to allogeneic stem-cell transplantation (SCT) (14%). No survival advantage could be demonstrated based on Hasle's classification or based on treatment. Conclusion: This report reflects the current practice in treating Brazilian children with MDS/JMML without specific Cooperative Group guidelines. Treatment modalities were very heterogeneous. The strategies for implementing a national protocol should consider international guidelines and focus on local experience and available resources. (C) 2004 Elsevier Ltd. All rights reserved.

THERE GOES THE ELECTORAL NEIGHBORHOOD: LOCAL NETWORKS, ATTRIBUTION OF RESPONSIBILITY, AND THE (UN) FAIRNESS OF ELECTIONS

During the last two decades there have been but a handful of recorded cases of electoral fraud in Latin America. However, survey research consistently shows that often citizens do not trust the integrity of the electoral process. This dissertation addresses the puzzle by explaining the mismatch between how elections are conducted and how the process is perceived. My theoretical contribution provides a double-folded argument. First, voters’ trust in their community members (“the local experience”) impacts their level of confidence in the electoral process. Since voters often find their peers working at polling stations, negative opinions about them translate into negative opinions about the election. Second, perceptions of unfairness of the system (“the global effect”) negatively impact the way people perceive the transparency of the electoral process. When the political system fails to account for social injustice, citizens lose faith in the mechanism designed to elect representatives -and ultimately a set of policies. The fact that certain groups are systematically disregarded by the system triggers the notion that the electoral process is flawed. This is motivated by either egotropic or sociotropic considerations. To test these hypotheses, I employ a survey conducted in Costa Rica, El Salvador, Honduras, and Guatemala during May/June 2014, which includes a population-based experiment. I show that Voters who trust their peers consistently have higher confidence in the electoral process. Whereas respondents who were primed about social unfairness (treatment) expressed less confidence in the quality of the election. Finally, I find that the local experience is predominant over the global effect. The treatment has a statistically significant effect only for respondents who trust their community. Attribution of responsibility for voters who are skeptics of their peers is clear and simple, leaving no room for a more diffuse mechanism, the unfairness of the political system. Finally, now I extend analysis to the Latin America region. Using data from LAPOP that comprises four waves of surveys in 22 countries, I confirm the influence of the “local experience” and the “global effect” as determinants of the level of confidence in the electoral process.

Pulmonary Hypertension in Latin America Pulmonary Vascular Disease: The Global Perspective

Latin America is here defined as all of the Americas south of the United States. In the setting of pulmonary hypertension, there are social inequalities and geophysical aspects in this region that account for a high prevalence of certain etiologies. This review aimed to analyze some of these factors. Data were collected from the existing literature. Information also was obtained from local tertiary-care centers to where patients with pulmonary hypertension generally are referred. Further, local experience and expertise was taken into consideration. Three etiologies of pulmonary hypertension were found to be the most prevalent: schistosomiasis (similar to 1 million affected people in Brazil), high altitude (particularly in the Andes), and congenital heart disease (late diagnosis of congenital left-to-right shunts leading to development of pulmonary vasculopathy). The diversity in terms of ancestries and races probably accounts for the differences in phenotype expression of pulmonary hypertension when a given region is considered (eg, schistosomiasis-, high-altitude-, or congenital heart disease-associated pulmonary hypertension). Governmental measures are needed to improve social and economic inequalities with an obvious impact on certain etiologies, such as schistosomiasis and congenital heart disease. Early diagnosis of pulmonary hypertension and access to medication remain important challenges all over Latin America. CHEST 2010; 137(6)(Suppl):78S-84S

Single institution outcomes of treatment of severe aplastic anaemia

Background: In severe aplastic anaemia, the treatment of choice for young patients with a human leucocyte antigen-matched sibling is now established as allogeneic bone marrow transplantation (BMT). In older patients and in those without a matched sibling donor, immunosuppressive therapy is the usual first option. 'Alternative' marrow donors are emerging as an option for those without a matched sibling donor. Aims: To review 10 years of local experience in treating severe aplastic anaemia with BMT and immunosuppressive therapy with emphasis on long-term outcomes. Methods: A retrospective analysis was performed of all patients with severe aplastic anaemia presenting to the Royal Brisbane and Royal Children's Hos- pitals between 1989 and 1999. Data were abstracted regarding patient demographics, pretreatment characteristics and outcome measures, including response rates, overall survival and long-term complications. Results: Twenty-seven consecutive patients were identified, 12 treated with immunosuppression alone and 15 with BMT. In these two groups, transfusion independence was attained in 25% and 100%, respectively, with overall survival being 36% and 100%, respectively. Those treated with immunosuppression were significantly older (median 41.5 versus 22 years, P = 0.008). Long-term survivors of either treatment had extremely low morbidity. Three patients carried pregnancies to term post-transplant. Three patients received alternative donor BMT with correspondingly excellent survival. Conclusions: Patients treated with allogeneic BMT for severe aplastic anaemia enjoyed extremely good long-term survival and minimal morbidity. Patients treated with immunosuppressive therapy had a poorer outcome reflecting their older age and different usage of therapies over the past decade. Optimal treatment strategies for severe aplastic anaemia remain to be determined.

Pilot study of induction chemotherapy followed by concomitant chemotherapy and IMRT or tomotherapy for nasopharyngeal carcinoma

Objective: Standard treatment of locally advanced (stages III and IV A-B) nasopharyngeal carcinoma (NPC) consists in chemoradiotherapy with 5-y survival rates of around 60%. However, acute toxicity prevents the administration of adequate adjuvant chemotherapy in nearly half of the patients. This situation has led to the hypothesis that induction chemotherapy followed by chemoradiotherapy may be a superior approach. Many ongoing studies are testing the role of induction chemotherapy in this setting. Newer radiotherapy techniques are becoming available (intensity modulated radiotherapy [IMRT] and tomotherapy). They can achieve a higher degree of accuracy in conforming the radiation to the planned target volume while sparing normal tissue resulting in less acute and long-term toxicity. Methods: We report here our local experience of 11 consecutive locally advanced NPC patients treated between June 2004 and October 2007. Median age was 46 years (range, 17-65). All but one were male patients. Initial stage was stage III in 5, and stage IVA-B in 6 patients. Treatment consisted of 3 cycles of induction TCF (Docetaxel 75 mg/m2- Cisplatin 75 mg/m2- 5-fluorouracil 750 mg/m2/d 5 days) chemotherapy followed by concomitant chemoradiotherapy with 3 cycles of cisplatin (100 mg/m2), or carboplatin (AUC 5) in case of renal impairment. Radiotherapy was delivered by either IMRT or tomotherapy. Macroscopic disease (tumor + involved lymph nodes) was treated with 70 Gy, 2 Gy/fraction (IMRT), or 69.6 Gy, 1.12 Gy/fraction (simultaneus integrated boost [SIB] technique). Elective nodal irradiation of 46-54 Gy lymph was performed in all patients, whereas elective irradiation of the entire nasopharynx (60 Gy) half of patients. Results: All but one tumor were EBV positive. Induction chemotherapy was done as planned for 8 patients (73%). Two patients had only 2 cycles, 1 patient had only1 cycle of TCF, and the other without docetaxel. Concomitant chemotherapy was given as planned in 7 patients (64%). Four patients had only 2 cycles. Radiotherapy could be delivered as planned in all patients. Eight weeks post treatment all patients proved to have a CR (CR or uCR). After a median follow-up of 11 months (range, 6-38 months) only one patient has relapsed. Details on acute and 1 year toxicities will be presented. Conclusion: Treatment of locally advancedNPC with induction and concomitant chemotherapy is feasible and well tolerated. The use of IMRT or tomotherapy technique seems to ameliorate the therapeutic index particularly in regard with xerostomia. All our patients presented a complete response. For the assessment of survival and long-term toxicity, a longer follow-up period is needed.

Lessons learned after 2 full scale disaster exercises in a Swiss pediatric hospital

Introduction: Following a disaster, up to 50% of mass casualties are children. The number of disaster increases worldwide, including in Switzerland. Following national order, the mapping of the various risks of disaster in Switzerland will be completed by the end of 2012. Pre-hospital disaster drills and plans are well established and regularly tested. In-hospital disaster plans are much less frequently tested, if only available. Pediatric in-hospital full scale disaster exercises have never been reported in Switzerland. Based on our local constraints, we set up and evaluated a disaster plan during two full scale exercises. Methods: In a university hospital treating more than 35 000 pediatric emergencies per year, two exercises involving mock victims of a disaster aged 9 to 14 years old were successively set up over a period of 3 years. The exercises were planned during the day, without modification of the normal emergency room activities. The hospital staff was informed and trained in advance. Variables such as the alarm timing and transmission, triage set-up and function, special disaster medical records utilization, communication and victims' identification were assessed. Family members participated in the second exercise. An evaluation team observed and record exercises activities, identifying strength and weaknesses. Results: On two separate occasions, a total of 44 mock patients participated, were triaged, admitted and treated in the hospital according to usual standards of care. Alarm transmission was not appropriate during the first exercise. Triage overload occurred on one occasion. In-hospital communication needed readjustment. Identification and in-hospital tracking of the children remained problematic. Hospital employees showed great enthusiasm and stressed the positive effect of full scale exercises on their knowledge of the hospital disaster plan. Conclusions: Performing real life disaster exercises in a pediatric hospital was very beneficial. The disaster plan was adapted to local needs and updated accordingly. An alarm transmission protocol was elaborated and tested. Triage set-up was adapted and tested. A hospital identification plan for injured children was created and tested. Full scale hospital exercises evaluating disaster plans revealed several weaknesses in the system. Practice readjustments based on local experience were made. A tested pediatric disaster plan adapted to local constraints could minimize chaos, optimize care and support in the event of a real disaster. Children's identification and family reunification following a disaster remains a challenge.

Arythmies foetales : extrasystoles et tachycardies supraventriculaires [Fetal arrhythmias: premature atrial contractions and supraventricular tachycardia]

Une arythmie foetale complique 1 à 2% des grossesses et présente dans 10% des cas un risque majeur de morbidité et de mortalité pour le foetus. Les arythmies les plus fréquentes sont les extrasystoles supraventriculaires (ESSV). Elles sont bénignes et se résolvent spontanément mais nécessitent un suivi visant à exclure un passage en tachycardie supraventriculaire (TSV). Les TSV sont plus rares mais sont fréquemment compliquées de décompensation cardiaque et d'anasarque. Heureusement, elles sont traitables in utero par pharmacothérapie. Nous rapportons ici notre expérience entre 2003 et 2005 avec de telles pathologies : parmi les 26 foetus adressés au Centre de cardiologie du CHUV, à Lausanne, et présentant des ESSV et/ou une TSV, aucun n'a souffert de complication sérieuse. Six ont bénéficié d'un traitement par sotalol en raison de TSV. Fetal arrhythmias form a complicating factor in 1-2% of all pregnancies and in 10% of those cases morbidity or even mortality is encountered. The most frequent occurring arrhythmias are premature atrial contractions (PAC). These are usually benign phenomena which resolve spontaneously, but require some follow-up to exclude the development of supraventricular tachycardias (SVT). SVTs are rare but are frequently complicated by fetal congestive heart failure or even fetal death. Timely prenatal pharmacotherapeutic intervention is generally advised to return to an adequate heart rate, preferably sinus rhythm. This study reports on the local experience with these forms of pathologies: of the 26 fetuses encountered with PAC or/and SVT between 2003 and 2005, none experienced serious complications, while 6 required pharmacotherapeutic intervention with sotalol.

Distribuição dos Hydrozoa até agora conhecidos nas costas do Brasil

This work was done with the aim of computing all the species of Hydrozoa (Siphonophora excluded) that have been collected on the Brazilian coast, or in the pelagial, near the coast (some of the "Meteor" Stations). Nutting's (1900, 1904, 1915) and Mayer's (1910) monographs were taken as starting points and later papers and the Zoological Record used to check posterior findings. As a whole, 116 different valid names, among species and forms, have been mentioned from the Brazilian coast, distributed among 60 genera. Of the 116 species, 82 are represented by hydropolyps, 30 by hydromedusae (11 of which belong to the Trachylina and therefore lack a polypoid generation) and finally, by 4 species of which are known both polypoid and medusoid generations. The subdivision of the coast has been made at random, on account of the scarcity of the findings, except for the best known district, that goes from the latitude of Vitoria (State of Espirito Santo, at about 20ºlat.S.) to the bay of Santos (State of São Paulo, about 24ºlat.S.). The latitude of Cabo Frio (23ºlat.S.) was considered as a possible natural barrier, and the results of the global counting of the distribution of the hydropolyps North and South of 23ºlat.S. is the following: 29 species are known only North of Cabo Frio, 26 only from the same latitude (see direction of the coast, along parallel 23ºS.) or further South and 28 species are known both North and South of the coast (of these, 5 species are "cosmopolitan"). Therefore it seems quite possible that Cabo Frio really is a barrier to the distribution of 55 species. 26 species are endemic to the Brazilian coast, of these, only 5 are found both North and South of the Cape, while-14 are found only North and 7 only South. No studies can be done, on the bathymetric distribution in relation to the latitude. These results must be considered as provisory since more extensive researches will probably alter these figures. However, I believe that they are significative as a mean index of the condition of the hydrozoan fauna of the Brazilian coast. A tentative working hypothesis is presented as to the possible factors that confer such a zoogeographic importance to the region of Cabo Frio, a fact that has been foreseen by Ekman (1935, p. 73). Geographic position, currents, latitude and nature of the sea bottom between the continent and the oceanic island of Trindade have been taken in consideration, and all of them seem to be possible eficient factors of separation. Furthermore, according to the data obtained by the "Meteor" Expedition in July 2, 1926, at station 164 (23º8'lat.S. - 42º5'long.W.) and station 165 (23º35'lat.S. - 40º52'long.W.) and by what is known by hearsay and local experience of the region (exact continued study is urgently needed), it seems possible that, off from the sharp curve that the coast has at Cabo Frio, there may be an irregularity of the general scheme of the current and local upwelling may be present that would explain the local low temperature, low salinity and high density of the superficial layers as well as the abundance of fishes; these factors might contribute towards the establishement of a zoogeographical barrier. Further work is needed and nothing more than an hypothesis can be presented for the moment.

Immersion professionnelle et intégration en emploi des immigrants : l’exemple du PRIIME (Programme d’aide à l’intégration des immigrants et des minorités visibles en emploi)

Les immigrants qualifiés rencontrent plusieurs obstacles sur le marché du travail au Québec. Parmi les plus importants, selon les employeurs, on note leur manque d’expérience québécoise. Le Programme d’aide à l’intégration des immigrants et minorités visibles en emploi (PRIIME), géré par Emploi-Québec, veut combler cette lacune en offrant aux immigrants une expérience québécoise dans leur domaine de qualification. Cette recherche a donc pour but d’examiner dans quelle mesure un programme d’immersion professionnelle tel que le PRIIME permet une meilleure intégration des immigrants qualifiés dans leur domaine et de voir si celle-ci se poursuit à la suite du programme. L’approche qualitative permet de mieux comprendre les différents points de vue : employeurs, immigrants et intervenants au PRIIME. On observe que la participation des immigrants au PRIIME permet de réduire leur degré de déqualification en emploi, mais pas complètement. Ainsi elle permet souvent de retrouver un emploi lié au domaine de formation, mais en dessous du niveau de qualifications des immigrants. Le PRIIME rend également possible un maintien en emploi, sauf que l’effet n’est observé qu’à court terme. De plus, la participation au programme ne suffit pas pour que l’immigrant soit en mesure de contrer les obstacles à l’intégration professionnelle, car les quatre volets principaux du PRIIME sont très rarement appliqués ensemble dans une entreprise. Finalement, dans la perspective des marchés transitionnels de travail, la participation au PRIIME représente une « transition critique » offrant aux immigrants une meilleure intégration professionnelle à long terme. En somme, nous concluons que le PRIIME réduit uniquement le degré de déqualification des immigrants en les rapprochant de leur domaine de formation. Toutefois, il ne tient pas compte du niveau d’éducation de la personne. Même avec le PRIIME, plusieurs immigrants se voient forcés de recommencer leur carrière.

A vision for attaining food security

Food is fundamental to human wellbeing and development. Increased food production remains a cornerstone strategy in the effort to alleviate global food insecurity. But despite the fact that global food production over the past half century has kept ahead of demand, today around one billion people do not have enough to eat, and a further billion lack adequate nutrition. Food insecurity is facing mounting supply-side and demand-side pressures; key among these are climate change, urbanisation, globalisation, population increases, disease, as well as a number of other factors that are changing patterns of food consumption. Many of the challenges to equitable food access are concentrated in developing countries where environmental pressures including climate change, population growth and other socio-economic issues are concentrated. Together these factors impede people's access to sufficient, nutritious food; chiefly through affecting livelihoods, income and food prices. Food security and human development go hand in hand, and their outcomes are co-determined to a significant degree. The challenge of food security is multi-scalar and cross-sector in nature. Addressing it will require the work of diverse actors to bring sustained improvements inhuman development and to reduce pressure on the environment. Unless there is investment in future food systems that are similarly cross-level, cross-scale and cross-sector, sustained improvements in human wellbeing together with reduced environmental risks and scarcities will not be achieved. This paper reviews current thinking, and outlines these challenges. It suggests that essential elements in a successfully adaptive and proactive food system include: learning through connectivity between scales to local experience and technologies high levels of interaction between diverse actors and sectors ranging from primary producers to retailers and consumers, and use of frontier technologies.

An assessment of the economic and social impacts of climate change on the Coastal and Marine Sector in the Caribbean

Climate change poses special challenges for Caribbean decision makers related to the uncertainties inherent in future climate projections and the complex linkages between climate change, physical and biological systems, and socioeconomic sectors. At present, however, the Caribbean subregion lacks the adaptive capacity needed to address these challenges. The present report assesses the economic and social impacts of climate change on the coastal and marine sector in the Caribbean until 2050. It aims both to provide Caribbean decision makers with cutting edge information on the vulnerability to climate change of the subregion, and to facilitate the development of adaptation strategies informed by both local experience and expert knowledge.
