Because current reperfusion strategies in acute myocardial infarction (AMI) seem to be exhausted in terms of additional mortality benefit, there remains a need for new methods to attenuate reperfusion injury and, thereby, further reduce myocardial infarct size and improve long-term survival. Therapeutic hypothermia (32-35°C) diminishes reperfusion injury and reduces infarct size in a variety of animal models of AMI if provided before reperfusion. In human studies this reduction has not been confirmed so far, most likely because systemic cooling acts slowly, and therefore, the target temperature is not reached in time or at all in a substantial number of patients...

BACKGROUND: Rates of hypothermia for women undergoing spinal anesthesia for cesarean delivery are high and prevention is desirable. This trial compared the effectiveness of preoperative warming versus usual care among women receiving intrathecal morphine, which is thought to exacerbate perioperative heat loss. METHODS: A prospective, single-blinded, randomized controlled trial compared 20 minutes of forced air warming (plus intravenous fluid warming) versus no active preoperative warming (plus intravenous fluid warming) in 50 healthy American Society of Anesthesiologists graded II women receiving intrathecal morphine as part of spinal anesthesia for elective cesarean delivery...

Copper (Cu) and iron (Fe), the enzymatic cofactors required for various biochemical processes, have been recently linked to lipid metabolism. Adipose tissues play central roles in energy balance and whether copper and iron homeostasis is involved in cold-stimulated energy metabolism remain unknown. In this study, the Cu and Fe contents in interscapular brown adipose tissue (BAT) and subcutaneous white adipose tissue (WAT) from mice at different developmental stages were measured. Our results revealed the dynamic changes of Cu and Fe levels during development, suggesting their potential roles in energy homeostasis...

In November and December of 2013, a large mortality event involving 15,000 - 20,000 eared grebes (Podiceps nigricollis) occurred at the Great Salt Lake (GSL), UT. The onset of the outbreak in grebes was followed by a mortality event in > 86 bald eagles (Haliaeetus leucocephalus). During the die-off, West Nile virus (WNV) was detected by RT-PCR or viral culture in carcasses of grebes and eagles submitted to the National Wildlife Health Center. However, no mosquito activity, the primary vector of WNV, was detected by the State of Utah's WNV monitoring program...

Pigs lack functional UCP1 making them susceptible to cold. Nevertheless, several pig breeds are known to be cold resistant. The molecular mechanism(s) enabling such adaptation are currently unknown. Here, we show that this resistance is not dependent on shivering, but rather depends on UCP3 and white adipose tissue (WAT) browning. In two cold-resistant breeds (Tibetan and Min), but not a cold-sensitive breed (Bama), WAT browning was induced after cold exposure. Beige adipocytes from Tibetan pigs exhibited greater oxidative capacity than those from Bama pigs...

Palisaded neutrophilic and granulomatous dermatitis and interstitial granulomatous dermatitis are uncommon granulomatous dermatoses that often arise in association with rheumatoid arthritis. These 2 entities have overlapping features and may exist on a spectrum. We report an intriguing case of a 53-year-old man with advanced rheumatoid arthritis who presented with a large indurated painful truncal plaque with a palpable cord in addition to a papulonodular eruption on his dorsal hands. Furthermore, our patient had a recurrence in a near-identical mirror-image pattern on the contralateral trunk...

Targeted temperature management (TTM) has been recognized to protect tissue function and positively influence neurological outcomes after brain injury. While shivering during hypothermia nullifies the beneficial effect of TTM, traditionally, antishivering drugs or paralyzing agents have been used to reduce the shivering. The hypothalamic area of the brain helps in controlling cerebral temperature and body temperature through interactions between different brain areas. Thus, modulation of different brain areas either pharmacologically or by electrical stimulation may contribute in TTM; although, very few studies have shown that TTM might be achieved by activation and inhibition of neurons in the hypothalamic region...

We report the case of previously healthy 14 years old male who presented high grade fever and headache. There was a history of convulsion at age of 7 years, so MRI Brain was done. It was suggestive of a central nervous system neoplasm. Our patient had only two days of fever which is an unusual presentation of a neoplasm. The paper should be of interest to the clinicians as neoplastic fever as cause of acute febrile illness is considered as a remote possibility.

Inadvertent perioperative hypothermia is estimated to affect 70% of surgical patients and is associated with adverse clinical outcomes, lengthened hospital stays, and increased costs. To better understand the current level of nursing knowledge on this subject since the release of the "Guideline for prevention of unplanned patient hypothermia," we conducted an e-mail survey of AORN members. The overall response rate was 6.5% (N = 324), and most responding nurses overestimated or underestimated the lower and upper limits for normothermia...

The present study examined the effect of meals varying in amount, size, and hardness of food pieces on the development of the chewing capabilities of 8-month-old infants. The study also examined changes in shivering, gagging, coughing, choking, and their ability to eat from a spoon. In an in-home setting two groups were given commercially available infant meals and fruits, purees with either less, smaller and softer or more, larger and harder pieces. Both groups were given these foods for 4 weeks and were monitored several times during this period...

Brown adipose tissue (BAT) is a specialized tissue critical for non-shivering thermogenesis producing heat through mitochondrial uncoupling; whereas white adipose tissue (WAT) is responsible of energy storage in the form of triglycerides. Another type of fat has been described, the beige adipose tissue; this tissue emerges in existing WAT depots but with thermogenic ability, a phenomenon known as browning. Several peripheral signals relaying information about energy status act in the brain, particularly the hypothalamus, to regulate thermogenesis in BAT and browning of WAT...

Brown adipose tissue (BAT) is critical for mammal's survival in the cold environment. Uncoupling protein 1 (UCP1) is responsible for the non-shivering thermogenesis in the BAT. Pig is important economically as a meat-producing livestock. However, whether BAT or more precisely UCP1 protein exists in pig remains a controversy. The objective of this study was to ascertain whether pig has UCP1 protein. In this study, we used rapid amplification of cDNA ends (RACE) technique to obtain the UCP1 mRNA 3' end sequence, confirmed only exons 1 and 2 of the UCP1 gene are transcribed in the pig...
