Therapeutic hypothermia is commonly used to improve neurological outcomes in patients after cardiac arrest. However, therapeutic hypothermia increases sepsis risk and unintentional hypothermia in surgical patients increases infectious complications. Nonetheless, the molecular mechanisms by which hypothermia dysregulates innate immunity are incompletely(More)
Trauma patients frequently have serious chest injuries. Retained hemothoraces and persistent pneumothoraces are among the most frequent complications of chest injuries which may lead to major, long-term morbidity and mortality if these complications are not recognized and treated appropriately. Video-assisted thoracoscopy (VATS) is a well-established(More)
INTRODUCTION Hypothermia occurs in as many as 7% of elective colorectal operations and is an underestimated risk factor for complications and death. Rewarming of hypothermic patients alone is not sufficient to prevent such adverse events. We investigated the outcomes of patients who became hypothermic (<35°C) after elective operations and compared them with(More)
BACKGROUND Persistent and tertiary chronic peritonitis is a clinically challenging problem especially in those who are critically ill. This could be attributed to a state of immune-paralysis, known as microbial tolerance. Microbial tolerance is the diminished pro-inflammatory protein response following repeated stimulation by numerous pathogen-associated(More)
OBJECTIVE To investigate whether warming to normal body temperature or to febrile range temperature (39°C) is able to reverse the detrimental effects of hypothermia. BACKGROUND Unintentional intraoperative hypothermia is a well-described risk factor for surgical site infections but also sepsis. We have previously shown that hypothermia prolongs the(More)
We observed persistent peritoneal bacteria despite a transient early innate immune response to intraperitoneal (IP) Klebsiella pneumoniae. Pretreatment with LPS prior to peritonitis induced a tolerant pattern of pro-inflammatory cytokine protein production over 72 h, but not at the mRNA level. MicroRNAs (miRNAs) regulate inflammatory cytokines and may(More)
Lung cancer is the most lethal cancer due to late detection in advanced stages; early diagnosis of lung cancer allows surgical treatment and improves the outcome. The prevalence of gastroesophageal reflux-related adenocarcinomas of the esophagus is increasing; repetitive surveillance endoscopies are necessary to detect development of cancer. A blood-based(More)
Unintentional hypothermia is a well-described risk factor for death and complications after elective and emergency surgery. The molecular mechanisms by which hypothermia exerts its detrimental effects are not well understood. Differences in cytokine production and the overall cell function have been reported under hypothermic conditions. We investigated the(More)
We have reported a new phenomenon in acute wound healing following the use of intracellular ATP delivery-extremely rapid tissue regeneration, which starts less than 24 h after surgery, and is accompanied by massive macrophage trafficking, in situ proliferation, and direct collagen production. This unusual process bypasses the formation of the traditional(More)
