Decapoda and Decapod larvae in the surface plankton from the Southern North Sea near "Texel" lightship

INTRODUCTION From mid-January 1961 until the end of 1966 macroplankton was collected by the crew of "Texel" lightship (position: 53°01'30"Ν 04°22' E) and identified afterwards in the Nederlands Instituut voor Onderzoek der Zee, at that time still in Den Helder. The nets, of Saran gauze with a 2 mm mesh and an opening of 1 m2, were originally intended for catching elvers, for investigations reported upon by Creutzberg, 1961. The original aim of the present plankton project was to catch Scyphomedusae, but soon after it had been started all the available macroplankton was sorted out and, if possible, identified. This explains why the decapod larvae, dealt with in the present paper, came to be collected by nets, quite unfit for that purpose. When the meshes are open, most of the smaller larvae can pass through, but when they are blocked, e.g. by algae or, as happens to be the case in midsummer, by enormous quantities of echinoderm larvae, then great quantities of smaller organisms may suddenly turn up in the catches. Therefore the number of larvae caught does not give a reliable picture of the numbers actually present in the plankton. The postlarval and the later stages of the Natantia have been identified by the second author (H.). The identification of the adult Reptantia has also been checked by him. The larvae of the Reptantia have been identified by the third author (S.). The identification is based on the keys and descriptions as given by Lebour (1928, 1943, 1944) and by MacDonald, Pike & Williamson (1957). For the data on occurrence of Pandalus and various other species in th

Electronic Health Program to Empower Patients in Returning to Normal Activities After General Surgical and Gynecological Procedures: Intervention Mapping as a Useful Method for Further Development

Contains fulltext : 215610.pdf (publisher's version ) (Open Access)BACKGROUND: Support for guiding and monitoring postoperative recovery and resumption of activities is usually not provided to patients after discharge from the hospital. Therefore, a perioperative electronic health (eHealth) intervention ("ikherstel" intervention or "I recover" intervention) was developed to empower gynecological patients during the perioperative period. This eHealth intervention requires a need for further development for patients who will undergo various types of general surgical and gynecological procedures. OBJECTIVE: This study aimed to further develop the "ikherstel" eHealth intervention using Intervention Mapping (IM) to fit a broader patient population. METHODS: The IM protocol was used to guide further development of the "ikherstel" intervention. First, patients' needs were identified using (1) the information of a process evaluation of the earlier performed "ikherstel" study, (2) a review of the literature, (3) a survey study, and (4) focus group discussions (FGDs) among stakeholders. Next, program outcomes and change objectives were defined. Third, behavior change theories and practical tools were selected for the intervention program. Finally, an implementation and evaluation plan was developed. RESULTS: The outcome for an eHealth intervention tool for patients recovering from abdominal general surgical and gynecological procedures was redefined as "achieving earlier recovery including return to normal activities and work." The Attitude-Social Influence-Self-Efficacy model was used as a theoretical framework to transform personal and external determinants into change objectives of personal behavior. The knowledge gathered by needs assessment and using the theoretical framework in the preparatory steps of the IM protocol resulted in additional tools. A mobile app, an activity tracker, and an electronic consultation (eConsult) will be incorporated in the further developed eHealth intervention. This intervention will be evaluated in a multicenter, single-blinded randomized controlled trial with 18 departments in 11 participating hospitals in the Netherlands. CONCLUSIONS: The intervention is extended to patients undergoing general surgical procedures and for malignant indications. New intervention tools such as a mobile app, an activity tracker, and an eConsult were developed.
