RESUMEN

Artificial Gene Drive (GD) may offer a number of transformative impacts on society. Despite potential usage in the area of conservation, GD remains largely unfamiliar to the public and little is known about their views. In our study, participants from New Zealand were placed in groups based upon one of four worldviews. They had a brief free word association session before considering a concise, technical definition of GD and were asked to discuss their views. Overall, discussions made use of narrative devices that expressed caution and concern around large-scale technological intervention with the natural world. However, specific worldviews presented unique themes. While fears of human overstep causing uncontrollable feedback across wild species and environments were universally present, this differed according to the group's worldview. We conclude that conversations on such technologies, especially those relating to gene modification, provide insight into deep-rooted social, cultural and even metaphysical concerns that transcend the technology's stated purpose.

RESUMEN

Introduced wasps (Vespula germanica and V. vulgaris) are costly invertebrate pests in New Zealand, with large impacts on the local ecology and economy. Wasps eat honeybees (Apis mellifera), which has potentially devastating effects on hive health, as well as agricultural and horticultural industries. Vespex bait, which contains fipronil in a proteinaceous carrier, has recently been introduced for wasp control. In over a decade of reported trials, honeybees have never been observed foraging on Vespex, likely because the bait contains no sugars to serve as a bee food source. However, the potential for the control agent fipronil to enter beehives has not been tested. Therefore, here, we investigated this using a liquid chromatography-mass spectrometry assay of fipronil and two of its environmental breakdown and metabolic derivatives, fipronil desulfinyl and fipronil sulfone. We did not detect fipronil in any of the worker bee, bee larva, honey or pollen samples (n = 120 per product) collected from 30 hives over a 2-year period. Furthermore, although we detected fipronil desulfinyl in one honeybee sample, this is thought to have originated from a single individual, representing a rare occurrence of intoxication, and there was no evidence that Vespex was the toxicant source. There was also no evidence of trophallactic transfer of fipronil or its derivatives in any of the hives sampled. Previous studies have reported the impairment of individual bee performance at fipronil doses similar to the detection limit of our study. However, our results provide confidence that if undetectable intoxication was occurring, it would involve an acute exposure for those few individuals affected, with minimal impairment to colonies. Therefore, we conclude that the use of Vespex in the vicinity of honeybees does not result in significant hive uptake while effectively reducing wasp pressure on honeybee colonies.

RESUMEN

Surgical treatment of morbid obesity continues to increase in popularity. The evolution of laparoscopic techniques has in part fueled that popularity. A common obstacle in achieving exposure of the angle of His during a laparoscopic Roux-en-Y gastric bypass is a massively enlarged liver. Exposure of the angle of His is key to successfully creating the gastric pouch and completing the gastrojejunostomy. Several well-described techniques exist to achieve this exposure but suffer from potential draw backs such as bleeding and the need to insert additional trocars. We describe a technique that allows safe, excellent exposure of the gastroesophageal junction during laparoscopic Roux-en-Y gastric bypass.

RESUMEN

Morbid obesity is an epidemic in this country. An increasing number of patients are undergoing weight loss surgery in an effort to combat the negative physical and psychological impact of morbid obesity. Fueling the increasing interest in surgical treatment of morbid obesity has been the development of new laparoscopic techniques. There are several surgical approaches to morbid obesity, and each has its own unique set of risks and potential complications. As more patients have weight loss surgery, clinicians working in the emergency department will frequently encounter complications of these procedures. To ensure timely diagnosis and optimal care, clinicians should be familiar with the standard weight loss approaches and the potential complications of these interventions.
