South and South-East Asian coastal fisheries: their status and directions for improved management: conference synopsis and recommendations
As a step to address the problems of coastal fisheries in Asia, the WorldFish Center joined forces with fisheries agencies from eight developing Asian countries (Bangladesh, India, Indonesia, Malaysia, The Philippines, Sri Lanka, Thailand and Vietnam) and the Asian Development Bank, to implement a project entitled âSustainable Management of Coastal Fish Stocks in Asiaâ (also known as the âTrawlBaseâ project). The project was implemented between 1998 and 2001. The main achievements of this partnership were: (a) Development of a database called âFisheries Resource Information System and Toolsâ (FiRST), which contains trawl research survey data and socioeconomic information for selected fisheries, and facilitates its analysis; (b) Evaluation of the extent of resource decline and over-fishing, both biological and economic, in the region; (c) Identification of the measures needed to manage coastal fisheries in the participating countries, resulting in draft strategies and action plans; and (d) Strengthening of national capacity in coastal fisheries assessment, planning and management
South and south-east Asian coastal fisheries: their status and directions for improved management: conference synopsis and recommendations
As a step to address the problems of coastal fisheries in Asia, the WorldFish Center joined forces with fisheries agencies from eight developing Asian countries (Bangladesh, India, Indonesia, Malaysia, The Philippines, Sri Lanka, Thailand and Vietnam) and the Asian Development Bank, to implement a project entitled ÎSustainable Management of Coastal Fish Stocks in Asiaö (also known as the ÎTrawlBaseö project). The project was implemented between 1998 and 2001. The main achievements of this partnership were: (a) Development of a database called ÎFisheries Resource Information System and Toolsö (FiRST), which contains trawl research survey data and socioeconomic information for selected fisheries, and facilitates its analysis; (b) Evaluation of the extent of resource decline and over-fishing, both biological and economic, in the region; (c) Identification of the measures needed to manage coastal fisheries in the participating countries, resulting in draft strategies and action plans; and (d) Strengthening of national capacity in coastal fisheries assessment, planning and management. The analyses show an alarming decline in coastal fishery resources throughout the region, with biomasses down to 5 - 30% of levels prior to the expansion of fishing. The relative abundance of the larger, more valuable fish has decreased sharply and that there has been a proportionate increase in smaller, less valuable species. The socioeconomic characteristics of the coastal fisheries, including fleet dynamics and cost efficiency has also been documented. These results provide a clear picture of the extent of stock rehabilitation and management required to restore maximum economic value to the fisheries of the region. The project has contributed to increasing awareness of key issues and opportunities in coastal fisheries management at the national and regional levels and illustrated the benefits of collaborative efforts in addressing issues of regional concern. It has also highlighted the need and urgency for concerted action at various levels of the institutional hierarchy to successfully resolve fisheries issues. There is a need to foster regional/national collaboration and cooperation among scientists and institutions involved in assessment and management of coastal fisheries. These gains provide the base (and momentum!) for the effective follow-up actions by the countries and international agencies to sustain the benefits derived from coastal fisheries by developing Asian countries. The directions for follow-up action towards improving the management of coastal fisheries resources presented in this paper were based on the results of a multisec-toral consultation conducted in the region. The main goal of fisheries management suggested is the sustainable utilization of coastal fishery resources in South and Southeast Asia, defined with environmental, socioeconomic and institutional objectives. Eight interventions to achieve these objectives are presented. These are grouped into interventions for implementation by the national fisheries institutions in the respective countries and regional support activities. We also urge that the countries must commit to continuous, long-term capacity building and institu-tional strengthening.Fishery management, Coastal fisheries, Southeast Asia, Bangladesh, India, Sri Lanka,

Predictors for anastomotic leak, postoperative complications, and mortality after right colectomy for cancer: Results from an international snapshot audit
Background: A right hemicolectomy is among the most commonly performed operations for colon cancer, but modern high-quality, multination data addressing the morbidity and mortality rates are lacking. Objective: This study reports the morbidity and mortality rates for right-sided colon cancer and identifies predictors for unfavorable short-term outcome after right hemicolectomy. Design: This was a snapshot observational prospective study. Setting: The study was conducted as a multicenter international study. Patients: The 2015 European Society of Coloproctology snapshot study was a prospective multicenter international series that included all patients undergoing elective or emergency right hemicolectomy or ileocecal resection over a 2-month period in early 2015. This is a subanalysis of the colon cancer cohort of patients. Main Outcome Measures: Predictors for anastomotic leak and 30-day postoperative morbidity and mortality were assessed using multivariable mixed-effect logistic regression models after variables selection with the Lasso method. Results: Of the 2515 included patients, an anastomosis was performed in 97.2% (n = 2444), handsewn in 38.5% (n = 940) and stapled in 61.5% (n = 1504) cases. The overall anastomotic leak rate was 7.4% (180/2444), 30-day morbidity was 38.0% (n = 956), and mortality was 2.6% (n = 66). Patients with anastomotic leak had a significantly increased mortality rate (10.6% vs 1.6% no-leak patients; p 65 0.001). At multivariable analysis the following variables were associated with anastomotic leak: longer duration of surgery (OR = 1.007 per min; p = 0.0037), open approach (OR = 1.9; p = 0.0037), and stapled anastomosis (OR = 1.5; p = 0.041). Limitations: This is an observational study, and therefore selection bias could be present. For this reason, a multivariable logistic regression model was performed, trying to correct possible confounding factors. Conclusions: Anastomotic leak after oncologic right hemicolectomy is a frequent complication, and it is associated with increased mortality. The key contributing surgical factors for anastomotic leak were anastomotic technique, surgical approach, and duration of surgery
Multi-messenger Observations of a Binary Neutron Star Merger
International audienceOn 2017 August 17 a binary neutron star coalescence candidate (later designated GW170817) with merger time 12:41:04 UTC was observed through gravitational waves by the Advanced LIGO and Advanced Virgo detectors. The Fermi Gamma-ray Burst Monitor independently detected a gamma-ray burst (GRB 170817A) with a time delay of with respect to the merger time. From the gravitational-wave signal, the source was initially localized to a sky region of 31 deg(2) at a luminosity distance of Mpc and with component masses consistent with neutron stars. The component masses were later measured to be in the range 0.86 to 2.26 . An extensive observing campaign was launched across the electromagnetic spectrum leading to the discovery of a bright optical transient (SSS17a, now with the IAU identification of AT 2017gfo) in NGC 4993 (at ) less than 11 hours after the merger by the One-Meter, Two Hemisphere (1M2H) team using the 1 m Swope Telescope. The optical transient was independently detected by multiple teams within an hour. Subsequent observations targeted the object and its environment. Early ultraviolet observations revealed a blue transient that faded within 48 hours. Optical and infrared observations showed a redward evolution over âŒ10 days. Following early non-detections, X-ray and radio emission were discovered at the transientâs position and days, respectively, after the merger. Both the X-ray and radio emission likely arise from a physical process that is distinct from the one that generates the UV/optical/near-infrared emission. No ultra-high-energy gamma-rays and no neutrino candidates consistent with the source were found in follow-up searches. These observations support the hypothesis that GW170817 was produced by the merger of two neutron stars in NGC 4993 followed by a short gamma-ray burst (GRB 170817A) and a kilonova/macronova powered by the radioactive decay of r-process nuclei synthesized in the ejecta
