    Notes: Summary Collection or storage of insects in 70% IPA was found to cause loss of body weight, major loss of nonpolar insecticides from submerged specimens, and transfer of insecticide to previously uncontaminated specimens. These effects may by no means be limited to mirex, since any chlorinated hydrocarbon is relatively lipophilic and may behave similarly. Residues reported for treated insects that have been collected or stored in alcohol may have been reduced to 12% of the original value. Moreover, small untreated vertebrates and invertebrates trapped in alcohol with insecticideladen insects are likely to absorb significant amounts of insecticide from the solution. The changes in residue levels owing to the 70% IPA used, though variable, were found to be as large as an order of magnitude, and the use of a correction factor would be badly misleading.

    Notes: Summary Feeding relationships of adultEuparia castanea Serville andMartinezia dutertrei Chalumeau with their ant hosts were studied in the laboratory using the radioactive tracer32P.Euparia castanea was tested withSolenopsis geminata (F.),Martinezia dutertrei Chalumeau was tested withS. invicta Buren,S. richteri Forel, andS. geminata. Unlabeled beetles were exposed to various radioisotope labeled conditions for 24 hr and then checked for acquired radioactivity. In whole colony tests, both species of beetles acquired radioactivity.M. dutertrei obtained food from live ants, butE. castanea did not. Both species of beetles ate ant larvae.E. castanea also obtained food from ant larvae by strigilation. Neither species of beetle fed on ant feces or other secretions on the substrate. Both species of beetles obtained food by strigilation from fresh and decomposed worker ant cadavers.M. dutertrei also ate both kinds of ant cadavers. Both species of beetles also ate dead house flies, indicative of scavenging or feeding on ant booty.Martinezia dutertrei showed no preference for any particular ant species. Ants did not obtain food by trophallaxis or glandular secretion from either species of beetle.

    Description: Introduction Nurse led radial arterial access (RAA) is emerging as an attractive alternative to traditional physician-led access.[1] Methods A multidisciplinary program was developed by the nursing and medical teams in a busy tertiary cardiac centre performing over 3000 interventional cardiology procedures of which 90% of cases are done radially. Phase 1 of the training programme consisted of 50 procedures per nurse performed under direct consultant operator supervision. Phase 2 consisted of routine nurse led radial artery cannulation on unselected patients. In addition 2 sub-studies were performed an audit of patient experience comparing the two nurse practitioners with cardiology trainees. An audit of the time to sheath insertion was carried out. Results Technical success was defined as access within two puncture attempts. In phase 1 of the training two nurses were successful in 84% of cases. In this case cohort there were no identified vascular complications. One patient needed an alternate access route. In Phase 2 311 cases were performed independently on unselected patients. The technical success rate was 86.5% for both nurses in total in this cohort. This included a mixture of both right radial (249 cases) and left radial (25 cases) access. 8 of these were also PPCI cases. No major vascular complications were identified. In cases where no access after two attempts was secured access was gained by a consultant. In 6 cases ultrasound guidance was used by the consultant. A patient discomfort score was recorded immediately via a questionnaire post access procedure. Results were compared with cardiology trainees performing RAA in parallel, demonstrating excellent outcomes. Similarly when comparing difference between patient on table to sheath insertion times between trainees and nurses performing the radial access, nurse radial access had competitive outcomes. Discussion Nurse led RAA procedure is an advanced practice skill which can be adopted by appropriately trained and experienced senior members of the nursing team. The advantages include facilitating flow through the catheter lab, greater advocacy of patients through their clinical pathway and high levels of patient satisfaction.
