Sustainable organic plant breeding: Final report - a vision, choices, consequences and steps
In general, the characteristics of organic varieties - and by extension of organic plant breeding - differ from that of conventional breeding systems and conventional varieties. Realising an organic plant breeding system and subsequently steering it to meet changing demands is no less than a mammoth task. The many actions to be undertaken can be divided into short-term commercial and scientific activities, and longer or long-term commercial and scientific activities.
Action must be taken in the short-term to ensure adequate quantities of organically propagated plants and seed. This is vital in consideration of Regulation 2092/91/EC which states that, as of 1 January 2000, all propagating material used in organic production must be of organic origin.
Additional measures are needed to accelerate the development of organically propagated varieties. Within the breeding sector, variety groups should be established to streamline communication in the chain. Variety groups should have a large contingent of farmers, as well as representatives from the trade branch and breeders. Members should communicate intensively with each other, share experiences, and participate in trials and variety assessments. Questions, wishes and bottlenecks could be recorded by variety groups and passed on to other parties in the chain.
The practical details of the plant health concept which is at the basis of organic breeding must be worked out (operationalised). This will require scientific research, for example on:
root development and mineral absorption efficiency
weed suppressive capacity
in situ versus ex situ maintenance
resistance breeding in combination with cultivation measures
seed-transmitted diseases
adaptive capacity
alternatives for growth stimulants, silver nitrate and silver thiosulfate in the cultivation of cucumbers and pickles
Such research should be carried out by academic institutions (such as Wageningen University and Research Centre) in collaboration with Louis Bolk Institute, Stichting Zaadgoed and private companies. A platform should be established to make an inventory of problems and priorities and to develop research proposals. Farmers could contribute their ideas to the platform through the variety groups.
Conclusion
A plant breeding system for organic production should be based on the organic concept of plant health and on the organic position on chain relationships. As the total land area under organic production is still relatively small, it is unlikely that commercial breeders will make large investments to develop organic breeding programmes without financial support from other parties, i.e. the government. In this early stage, it is vital that the government provides generous funding and plays an active enabling role. We hope that the action plan to stimulate organic plant breeding, as requested by Parliament, will dovetail with the activities described above
âClip-Stoneâ Filiation Within the Biliary Tract
A case of cholangitis due to the migration of a metal clip used for surgical cholecystectomy 4 years
earlier, is reported. The diagnostic approach and therapeutic options, either endoscopic or surgical are
discussed. The use of resorbable clips during the performance of laparoscopic cholecystectomy should
avoid this type of complication
Protocolized Versus Nonprotocolized Weaning to Reduce the Duration of Invasive Mechanical Weaning in Neonates A Systematic Review of All Types of Studies
Mechanical ventilation is one of the most commonly used
treatments in neonatology. Prolonged mechanical ventilation is associated with deleterious outcomes. To reduce
the ventilation duration, weaning protocols have been developed to achieve extubation in adult and pediatric care
in a safe and uniform manner. We performed a systematic
review to obtain all available evidence on the effect of protocolized versus nonprotocolized weaning on the duration
of invasive mechanical ventilation in critically ill neonates.
The Cochrane Central Register of Controlled Trials,
MEDLINE, EMBASE, CINAHL, Web of Science, and the
International Clinical Trial Registry Platform were searched
until January 2018. Quantitative and qualitative studies
involving neonates that investigated or described protocolized versus nonprotocolized weaning were included.
Primary outcome was the difference in weaning duration.
A total of 2099 potentially relevant articles were retrieved.

Commuter lives: a review symposium on David Bissell's Transit Life
© 2019 Institute of Australian Geographers This article presents a series of commentaries on Transit Life: How Commuting is Transforming Our Cities, published by MIT Press in 2018. Centring on an inâdepth case study of Sydney, the book argues the need to attend carefully to the fineâgrained detail of the commuting experience. In all sorts of ways, Transit Life presents a way of thinking about urban transportation radically different from that used by mainstream transport planners and geographers. Geographical Research asked six researchersâTim Edensor, Michele Lobo, Debbie Hopkins, Helen Fitt, Juliana Mansvelt, and Donald McNeillâto reflect on what kind of research vistas might be opened up bring the tools of cultural geography and mobility research to the world of commuting. Here are their responses, rounded out by a reply by David Bissell, Transit Life's author
Tourism in Conflict Areas: Complex Entanglements in Jordan.
In this article the workings of tourism in areas of socio-political turmoil are critically examined. In so doing the aim is to scrutinize interconnections between tourism, safety and conflict as I contend that tourism, tourists and the danger generated by ongoing socio-political conflicts are intimately connected. The empirical focus is on tourism in Jordan, a country in a region troubled by ongoing conflicts. Fieldwork for this project was carried out in 2009 and 2010 and data was collected from local tourism industry representatives and international tourists in Jordan. Findings indicate that a safety/danger binary is destabilized by industry representatives who operate a âsanitizationâ process in Jordan meant to erase danger and conflicts from tourism spaces. Tourists in the region also disrupt this binary as they travel to the region in spite of the conflict and downplay violent incidents
The bilirubin albumin ratio in the management of hyperbilirubinemia in preterm infants to improve neurodevelopmental outcome: A randomized controlled trial - BARTrial
Background and Objective: High bilirubin/albumin (B/A) ratios increase the risk of bilirubin neurotoxicity. The B/A ratio may be a valuable measure, in addition to the total serum bilirubin (TSB), in the management of hyperbilirubinemia. We aimed to assess whether the additional use of B/A ratios in the management of hyperbilirubinemia in preterm infants improved neurodevelopmental outcome. Methods: In a prospective, randomized controlled trial, 615 preterm infants of 32 weeks' gestation or less were randomly assigned to treatment based on either B/A ratio and TSB thresholds (consensus-based), whichever threshold was crossed first, or on the TSB thresholds only. The primary outcome was neurodevelopment at 18 to 24 months' corrected age as assessed with the Bayley Scales of Infant Development III by investigators unaware of treatment allocation. Secondary outcomes included complications of preterm birth and death. Results: Composite motor (100±13 vs. 101±12) and cognitive (101±12 vs. 101±11) scores did not differ between the B/A ratio and TSB groups. Demographic characteristics, maximal TSB levels, B/A ratios, and other secondary outcomes were similar. The rates of death and/or severe neurodevelopmental impairment for th
