Integrated assessment of the Magdalena River Delta and estuary socio-ecological system

River-mouth systems and deltas are hotspots where many of the coastal symptoms can be found, moreover, these systems provide essential ecosystem services (e.g., recreation, food provisioning, protection against natural hazards). The present study focuses on the socio-ecological system (SES) that is present in the estuary formed in the central Caribbean Region in Colombia at the main river-mouth of the Magdalena River. This research seeks to assess the multidimensional sustainability of the Magdalena river-mouth system in order to improve the knowledge basis for its integrated management. To do so, an assessment tool named ‘Circles of Coastal Sustainability’ was used to evaluate the system splitting it into four domains (environmental, social, economic and governance) that were divided into 5 categories each. These domains were evaluated through a total of 52 indicators distributed like this: 16 for the Environmental domain, 16 for the Economic domain, 12 for the Social domain and, 8 for the Governance domain. The results show that the overall sustainability of the Magdalena River-mouth SES is classified as ‘Satisfactory’. None of the domains is in ‘Excellent’ or ‘Bad’ conditions. However, the evaluation of the categories shows that four (4) of them have ‘Poor’ conditions (i.e., Social Benefits, Demographics, Economic Security, and Resources Management). Hence, it is recommended to put those categories at the centre of the discussion to define management strategies (e.g., Preserving and restoring habitats; tackling sources of pollution and excessive sediment; local reduction of net GHG and adaptation to climate change; participation of local communities in the management design and implementation) without disregarding the interrelation with the other categories and dimensions. Finally, it is argued that despite all the improvement opportunities, the CCS is a valuable tool to evaluate the sustainability of coastal systems in Colombia and the world.This thesis is submitted by David Gallo Velez to the Alma Mater Studiorum – Università di Bologna, Italy in partial fulfilment of the requirements for the Erasmus Mundus Joint Master’s Degree in Water and Coastal Management (WACOMA), in conjunction with the Universidade do Algarve, Portugal and the Universidad de Cádiz, Spain.

A socio-ecological assessment of land-based contamination and pollution: The Magdalena delta, Colombia

River mouth systems, such as estuaries and deltas are important earth system transitional zones linking the land and coastal marine systems. They funnel anthropogenic contaminants and pollutants from the activities in the river catchment into the marine environment. The present study is focused on the Magdalena River-mouth at Bocas de Ceniza where land-based contamination and pollution are important issues. These were subsequently analysed using an expanded DPSIR framework (Drivers Pressures, State, Impacts Responses). Based on export coefficients and secondary information, the loads of BOD, TSS, Nutrients and solid waste from different sources were identified and compared to prioritize their management within the study area. Findings suggest that contaminants generated in the study area may be insignificant compared to the inputs from the Magdalena River, but they can have a significant impact on the state of local ecosystems. Of all the sources analysed, agriculture and livestock are theoretically the largest contributors of nitrogen (i.e., 14.84 t d(-1) and 48.99 t d(-1)) and phosphorus (i.e., 5.90 t d(-1) and 19.46 t d(-1)) in the basin 'Direct to the Caribbean' and 'Cienaga de Mallorquin' (that altogether are identified as DtC+) and the 'Western bank of the lower Magdalena' (DtM-LM), respectively. In the case of BOD, domestic and industrial wastewaters contribute about 5.10 t d(-1) and 98.43 t d(-1) in the same basins. Contributions of faecal coliforms were more than 4 orders of magnitude higher in untreated wastewater, being 4.86 x10(16) NMP d(-1) and 1.78 x10(16) NMP d(-1) in the lower Magdalena and Caribbean catchments, respectively. Inadequately managed waste and plastic represent a serious problem for the Caribbean Basin. Solid waste generated within the study area and coming from the Magdalena basin and the Caribbean Sea, reaches the coast and deteriorates its visual quality, affects mangrove ecosystems, and generates impacts on coastal populations. By basin, the DtM-LM is where the greatest pollutant loads are generated. However, in terms of impact on human well-being, it is the DtC+ that bears the brunt where pressures are translated in impacts such as increased maintenance and cleaning cost of beaches, reduction or loss of tourism revenue, adverse health effects to vulnerable groups, reduce protection against natural hazards, increased living costs and loss of cultural values.info:eu-repo/semantics/publishedVersio

Assessment of the Magdalena River delta socio-ecological system through the circles of coastal sustainability framework

River-mouth systems and deltas are hotspots where many of the coastal syndromes can be found. Moreover, these systems provide essential ecosystem services (e.g., recreation, food provisioning, protection against natural hazards). The present study focuses on the socio-ecological system at the delta of the Magdalena River in the central Caribbean Region in Colombia. This research seeks to assess the multidimensional sustainability of the Magdalena river-mouth system (MRm-SES) to improve the knowledge basis for its integrated management. To do so, an assessment tool named "Circles of Coastal Sustainability" (CCS) was used to evaluate the system splitting it into four domains (environmental, social, economic and governance) that were divided into 5 categories each. These domains were evaluated through a total of 52 indicators distributed like this: 16 for the Environmental domain, 16 for the Economic domain, 12 for the Social and Cultural domain and, 8 for the Governance domain. The results show that the overall sustainability of the MRm-SES is classified as "Satisfactory." None of the domains is in "Excellent" or "Bad" conditions. However, the evaluation of the categories shows that four (4) of them have "Poor" conditions (i.e., Social Benefits, Demographics, Economic Security, and Resources Management). Hence, it is recommended to put those categories at the centre of the discussion to define management strategies (e.g., Preserving and restoring habitats; tackling sources of pollution and excessive sediment; local reduction of net Greenhouse Gas and adaptation to climate change; participation of local communities in the management design and implementation), without disregarding the interrelation with the other categories and dimensions. Finally, it is argued that despite all the improvement opportunities, the CCS is a valuable tool to evaluate and communicate with different stakeholders (academic community, managers and decision-makers, local communities, etc.), to improve the sustainability of coastal systems in Colombia and the world.European Commission Joint Research Centre586596-EPP-1-2017-1-IT-EPPKA1-JMD-MOB, Fundação para a Ciência e a Tecnologia (FCT) LA/P/0069/2020,info:eu-repo/semantics/publishedVersio

Intraperitoneal drain placement and outcomes after elective colorectal surgery: international matched, prospective, cohort study

Despite current guidelines, intraperitoneal drain placement after elective colorectal surgery remains widespread. Drains were not associated with earlier detection of intraperitoneal collections, but were associated with prolonged hospital stay and increased risk of surgical-site infections.Background Many surgeons routinely place intraperitoneal drains after elective colorectal surgery. However, enhanced recovery after surgery guidelines recommend against their routine use owing to a lack of clear clinical benefit. This study aimed to describe international variation in intraperitoneal drain placement and the safety of this practice. Methods COMPASS (COMPlicAted intra-abdominal collectionS after colorectal Surgery) was a prospective, international, cohort study which enrolled consecutive adults undergoing elective colorectal surgery (February to March 2020). The primary outcome was the rate of intraperitoneal drain placement. Secondary outcomes included: rate and time to diagnosis of postoperative intraperitoneal collections; rate of surgical site infections (SSIs); time to discharge; and 30-day major postoperative complications (Clavien-Dindo grade at least III). After propensity score matching, multivariable logistic regression and Cox proportional hazards regression were used to estimate the independent association of the secondary outcomes with drain placement. Results Overall, 1805 patients from 22 countries were included (798 women, 44.2 per cent; median age 67.0 years). The drain insertion rate was 51.9 per cent (937 patients). After matching, drains were not associated with reduced rates (odds ratio (OR) 1.33, 95 per cent c.i. 0.79 to 2.23; P = 0.287) or earlier detection (hazard ratio (HR) 0.87, 0.33 to 2.31; P = 0.780) of collections. Although not associated with worse major postoperative complications (OR 1.09, 0.68 to 1.75; P = 0.709), drains were associated with delayed hospital discharge (HR 0.58, 0.52 to 0.66; P < 0.001) and an increased risk of SSIs (OR 2.47, 1.50 to 4.05; P < 0.001). Conclusion Intraperitoneal drain placement after elective colorectal surgery is not associated with earlier detection of postoperative collections, but prolongs hospital stay and increases SSI risk

Current immunogenetic predisposition to tuberculosis in the Moroccan population.

Tuberculosis (TB) is a serious infectious disease that kills approximately two million people per year, particularly in low- and middle-income countries. Numerous genetic epidemiology studies have been conducted of many ethnic groups worldwide and have highlighted the critical impact of the genetic environment on TB distribution. Many candidate genes associated with resistance or susceptibility to TB have been identified. In Morocco, where TB is still a major public health problem, various observations of clinical, microbiological and incidence distribution are heavily affected by genetic background and external environment. Morocco has almost the same clinical profile as do other North African countries, mainly the increase in more extrapulmonary than pulmonary forms of the diseases, when compared to European, Asian or American populations. In addition, a linkage analysis study that examined Moroccan TB patients identified a unique chromosome region that had a strong association with the risk of contracting TB. Other genes in the Moroccan population that were found to be associated seem to be involved predominantly in modulating the innate immunity. In this review, we appraise the major candidate genes that have been reported in Moroccan immunogenetic studies and discuss their updated role in TB, particularly during the first phase of the immune response to Mycobacterium tuberculosis (Mtb) infection
