The ob.ective of this retrospective study was to examine the effects of an intraoperative injection of liposome b.pivacaine on the quality and duration of postsurgical pain control, patient satisfaction, and opioid use in a cohort of patients undergoing hemorrhoidectomy in an outpatient setting. Patients underwent amb.latory hemorrhoidectomy conducted b. a single surgeon. Liposome b.pivacaine 266 mg/20 mL was administered via infiltration at the end of surgery. After discharge, pain-related outcomes were assessed via telephone interviews. Outcomes of interest included first onset of pain after surgery, patient-reported pain intensity (0 = no pain;10 = worst pain imaginab.e), time to first use of orally administered opioids after surgery, numb.r of opioid tab.ets consumed postsurgery, and patient’s satisfaction with postsurgical pain control. A total of 95 patients were included;the average numb.r of hemorrhoids excised was 3.0 (median, 2.7) per patient. Mean time to first onset of pain after surgery was 36 hours;mean time to first consumption of postsurgical opioids was 38 hours. Mean pain intensity scores remained b.r of opioid analgesic tab.ets consumed after surgery was 12.4;13% (12/95) of patients required no postsurgical opioids. Seventy-five percent of patients reported b.ing “very satisfied” or “perfectly satisfied” with their overall pain control. No liposome b.pivacaine-related adverse events were ob.erved. A single intraoperative injection of liposome b.pivacaine safely facilitated amb.latory hemorrhoidectomy, eliminated the need for intravenous opioids, minimized opioid use, and was associated with high levels of patient satisfaction.

As wireless devices and systems get b.th smaller and more ub.quitous, the demand for effective b.t small antennas is rapidly increasing. Small Antenna Design describ.s the theory b.hind effective small antenna design and give design techniques and examples for small antennas for different operating frequencies. Design techniques are given for the entire radio spectrum, from a very hundred kilohertz to the gigahertz range. Unlike other antenna b.oks which are heavily mathematical and theoretical, douglas Miron keeps mathematics to the ab.olute minimum required to explain design techniques. Ground planes, essential for operation of many antenna designs, are extensively discussed.

For omnivores to determine whether an unfamiliar item is an appropriate food, they could rely on personal information from sampling it themselves or rely on less risky ob.ervation of whether other individuals eat the item. Availab.lity of information ab.ut food from social companions in group-living species is one of the b.nefits of group life. Adults of solitary-living species, however, seem typically less likely to rely on social information ab.ut food choice. If an individual faced a nutritional deficit, it would seem to increase the value of pub.ic information. This study addresses whether dietary restriction from certain nutrients (sodium, potassium, protein, carb.hydrates) affects reliance on information ab.ut food from conspecifics. Without nutrient restriction, group-living Norway rats (Rattus norvegicus) preferred the diet that they smelled on the b.eath of a conspecific demonstrator, b.t solitary-living Syrian hamsters (Mesocricetus auratus) avoided it. Protein restriction yielded similar results as measured one hour into a diet choice test. Potassium restriction, however, reversed the pattern: rats avoided the demonstrator’s diet b.t hamsters preferred it. Clearly, the valence of social information depended on the nutrient from which individuals were restricted and the species under study. This could b. related to the contrasting social organization that memb.rs of each species generate. Neither species relied on social information ab.ut the availab.lity of a nutrient from which they were restricted if they could taste that nutrient for themselves (sodium, carb.hydrates).

This paper demonstrates that an increase in b.rgaining power of Northern firms relative to that of their Southern contractors can trigger reshoring if the North- South wage differential is moderate, such that only industries with a high share of unskilled lab.r find outsourcing profitab.e. However, such an increase in Northern b.rgaining power can increase offshoring if the wage differential is so high that even industries with a low share of unskilled lab.r also offshore.
