To dissect the role of constitutively altered Tgfbr1 signaling in pancreatic cancer development, we crossed Elastase-Kras(G12D) (EL-Kras) mice with Tgfbr1 haploinsufficient mice to generate EL-Kras/Tgfbr1(+/-) mice. Mice were euthanized at 6 to 9 months to compare the incidence, frequency, and size of precancerous lesions in the pancreas. Only 50% of all EL-Kras/Tgfbr1(+/-) mice developed preinvasive lesions compared with 100% of EL-Kras (wild-type Tgfbr1) mice. The frequency of precancerous lesions was 4-fold lower in haploinsufficient than in control mice. Paradoxically, the precancerous lesions of EL-Kras/Tgfbr1(+/-) mice were considerably larger than those in EL-Kras mice. Yet, the mitotic index of precancerous cells and the observable levels of fibrosis, lipoatrophy, and lymphocytic infiltration were reduced in EL-Kras/Tgfbr1(+/-) mice. We conclude that Tgfbr1 signaling promotes the development of precancerous lesions in mice. These findings suggest that individuals with constitutively decreased TGFBR1 expression may have a decreased risk of pancreatic cancer.

Tgfbr1 haploinsufficiency inhibits the development of murine mutant Kras-induced pancreatic precancer.

Therapeutic hypothermia or targeted temperature management has been used after cardiac arrest to improve neurological outcomes and mortality. However, a side effect of temperature modulation is a centrally mediated shivering response. The Columbia Anti-Shivering Protocol sets up a systematic method of intravenous (IV) and oral medication escalation to suppress this response and preserve the benefits of this therapy. We present the case of a 59-year-old male who began shivering after therapeutic hypothermia for cardiac arrest, leading to a persistent rise in core temperature despite adequate sedation. He was also found to have gastric contents similar to coffee grounds through nasogastric tube suction. The shivering was effectively suppressed and the rising core temperature plateaued using rectal acetaminophen and buspirone administered by means of a novel device, the Macy Catheter. Also, when used in conjunction with other protocol-driven medications, the patient was able to achieve a core temperature of 33°C. The Macy Catheter appears to be a useful approach to rectally administer buspirone and acetaminophen, using an easy-to-place, nonsterile atraumatic device that requires no radiographic confirmation of placement.
