The CAOF Agreement. Key Issues of International Fisheries Law

This Chapter is devoted to issues relating to the Agreement to Prevent Unregulated High Seas Fisheries in the Central Arctic Ocean and its negotiation that are of key importance to international fisheries law. It provides an overview of the Arctic Five and Five-plus-Five processes that culminated in the Agreement, as well as the Agreement’s institutional set-up and setting. These negotiation processes were confronted with a unique scenario in international fisheries law: they were in a position to collectively determine the conditions under which a future high seas fishery would be allowed to commence. The final package deal that led to the successful conclusion of the Five-plus-Five process was not only driven by the fundamentally different central Arctic Ocean fisheries interests of the Arctic Five on the one hand, and those of the Other Five on the other hand, but also by their broader interests in the domains of international fisheries law, the international law of the sea and the international law relating to the Arctic. Other key features of the Five-plusFive process that are examined in detail are its exploratory phase, the stepwise approach and the evolving nature of the Agreement

International Governance and Regulation of the Marine Arctic Three Reports Prepared for the WWF International Arctic Program

WWF commissioned these three reports to examine the current governance regime, identify governance and regulatory gaps and analyze options for improvements. The reports, which are authored by international legal experts Timo Koivurova and Erik J. Molenaar, conclude that one of the best options is to adopt a new multilateral agreement. WWF's goal is to work with arctic states and arctic Indigenous peoples to promote the closure of the 'governance gaps', protection and preservation of the Arctic Ocean and sustainable ecosystem-based management of its resources

Canada, the EU and Arctic Ocean Governance: A Tangled and Shifting Seascape and Future Directions

The objective of this paper is to examine (in a historical perspective) the roles of the European Union (EU) and Canada in governance and regulation of human activities in the Arctic Ocean. Section two describes the existing “tangled” nature of governance in the Arctic with a focus on law of the sea, approaches and challenges in the region, as well as on EU and Canadian participation in the activities of the Arctic Council. The “shifting seascape” in governance is next highlighted in section three with a review of increasing calls for change from scholars and other groups, recent governance initiatives from the United States and Arctic Ocean coastal states, and evolving EU and Canadian perspectives towards ocean governance. The paper concludes with section four, which surveys possible future directions for strengthening ocean governance in the Arctic, with the spectrum of options including, among others, expanding the spatial scopes of the North-East Atlantic Fisheries Commission (NEAFC), established by the NEAFC Convention, and the OSPAR Commission, established by the Convention for the Protection of the Marine Environment of the North-East Atlantic (OSPAR) Convention, and reform by means of an Implementing Agreement under the United Nations Convention on the Law of the Sea (LOS)

A cancer drug atlas enables synergistic targeting of independent drug vulnerabilities.

Personalized cancer treatments using combinations of drugs with a synergistic effect is attractive but proves to be highly challenging. Here we present an approach to uncover the efficacy of drug combinations based on the analysis of mono-drug effects. For this we used dose-response data from pharmacogenomic encyclopedias and represent these as a drug atlas. The drug atlas represents the relations between drug effects and allows to identify independent processes for which the tumor might be particularly vulnerable when attacked by two drugs. Our approach enables the prediction of combination-therapy which can be linked to tumor-driving mutations. By using this strategy, we can uncover potential effective drug combinations on a pan-cancer scale. Predicted synergies are provided and have been validated in glioblastoma, breast cancer, melanoma and leukemia mouse-models, resulting in therapeutic synergy in 75% of the tested models. This indicates that we can accurately predict effective drug combinations with translational value

Preoperative endoscopic versus percutaneous transhepatic biliary drainage in potentially resectable perihilar cholangiocarcinoma (DRAINAGE trial): Design and rationale of a randomized controlled trial

Background: Liver surgery in perihilar cholangiocarcinoma (PHC) is associated with high postoperative morbidity because the tumor typically causes biliary obstruction. Preoperative biliary drainage is used to create a safer environment prior to liver surgery, but biliary drainage may be harmful when severe drainage-related complications deteriorate the patients' condition or increase the risk of postoperative morbidity. Biliary drainage can cause cholangitis/cholecystitis, pancreatitis, hemorrhage, portal vein thrombosis, bowel wall perforation, or dehydration. Two methods of preoperative biliary drainage are mostly applied: endoscopic biliary drainage, which is currently used in most regional centers before referring patients for surgical treatment, and percutaneous transhepatic biliary drainage. Both methods are associated with severe drainage-related complications, but two small retrospective series found a lower incidence in the number of preoperative complications after percutaneous drainage compared to endoscopic drainage (18-25% versus 38-60%, respectively). The present study randomizes patients with potentially resectable PHC and biliary obstruction between preoperative endoscopic or percutaneous transhepatic biliary drainage. Methods/Design: The study is a multi-center trial with an "all-comers" design, randomizing patients between endoscopic or percutaneous transhepatic biliary drainage. All patients selected to potentially undergo a major liver resection for presumed PHC are eligible for inclusion in the study provided that the biliary system in the future liver remnant is obstructed (even if they underwent previous inadequate endoscopic drainage). Primary outcome measure is the total number of severe preoperative complications between randomization and exploratory laparotomy. The study is designed to detect superiority of percutaneous drainage: a provisional sample size of 106 patients is required to detect a relative decrease of 50% in the number of severe preoperative complications (alpha = 0.95; beta = 0.8). Interim analysis after inclusion of 53 patients (50%) will provide the definitive sample size. Secondary outcome measures encompass the success of biliary drainage, quality of life, and postoperative morbidity and mortality. Discussion: The DRAINAGE trial is designed to identify a difference in the number of severe drainage-related complications after endoscopic and percutaneous transhepatic biliary drainage in patients selected to undergo a major liver resection for perihilar cholangiocarcinoma.

The Effect of Interpersonal Psychotherapy and other Psychodynamic Therapies versus ‘Treatment as Usual’ in Patients with Major Depressive Disorder

Major depressive disorder afflicts an estimated 17% of individuals during their lifetimes at tremendous suffering and costs. Interpersonal psychotherapy and other psychodynamic therapies may be effective interventions for major depressive disorder, but the effects have only had limited assessment in systematic reviews.Cochrane systematic review methodology with meta-analysis and trial sequential analysis of randomized trials comparing the effect of psychodynamic therapies versus ‘treatment as usual’ for major depressive disorder. To be included the participants had to be older than 17 years with a primary diagnosis of major depressive disorder. Altogether, we included six trials randomizing a total of 648 participants. Five trials assessed ‘interpersonal psychotherapy’ and only one trial assessed ‘psychodynamic psychotherapy’. All six trials had high risk of bias. Meta-analysis on all six trials showed that the psychodynamic interventions significantly reduced depressive symptoms on the 17-item Hamilton Rating Scale for Depression (mean difference −3.12 (95% confidence interval −4.39 to −1.86;P<0.00001), no heterogeneity) compared with ‘treatment as usual’. Trial sequential analysis confirmed this result.We did not find convincing evidence supporting or refuting the effect of interpersonal psychotherapy or psychodynamic therapy compared with ‘treatment as usual’ for patients with major depressive disorder. The potential beneficial effect seems small and effects on major outcomes are unknown. Randomized trials with low risk of systematic errors and low risk of random errors are needed

Targeted locus amplification to develop robust patient-specific assays for liquid biopsies in pediatric solid tumors

BACKGROUND: Liquid biopsies combine minimally invasive sample collection with sensitive detection of residual disease. Pediatric malignancies harbor tumor-driving copy number alterations or fusion genes, rather than recurrent point mutations. These regions contain tumor-specific DNA breakpoint sequences. We investigated the feasibility to use these breakpoints to design patient-specific markers to detect tumor-derived cell-free DNA (cfDNA) in plasma from patients with pediatric solid tumors. MATERIALS AND METHODS: Regions of interest (ROI) were identified through standard clinical diagnostic pipelines, using SNP array for CNAs, and FISH or RT-qPCR for fusion genes. Using targeted locus amplification (TLA) on tumor organoids grown from tumor material or targeted locus capture (TLC) on FFPE material, ROI-specific primers and probes were designed, which were used to design droplet digital PCR (ddPCR) assays. cfDNA from patient plasma at diagnosis and during therapy was analyzed. RESULTS: TLA was performed on material from 2 rhabdomyosarcoma, 1 Ewing sarcoma and 3 neuroblastoma. FFPE-TLC was performed on 8 neuroblastoma tumors. For all patients, at least one patient-specific ddPCR was successfully designed and in all diagnostic plasma samples the patient-specific markers were detected. In the rhabdomyosarcoma and Ewing sarcoma patients, all samples after start of therapy were negative. In neuroblastoma patients, presence of patient-specific markers in cfDNA tracked tumor burden, decreasing during induction therapy, disappearing at complete remission and re-appearing at relapse. CONCLUSION: We demonstrate the feasibility to determine tumor-specific breakpoints using TLA/TLC in different pediatric solid tumors and use these for analysis of cfDNA from plasma. Considering the high prevalence of CNAs and fusion genes in pediatric solid tumors, this approach holds great promise and deserves further study in a larger cohort with standardized plasma sampling protocols
