Balancing Model Performance and Simplicity to Predict Postoperative Primary Care Blood Pressure Elevation.
Because of uncertainty regarding the reliability of perioperative blood pressures and traditional notions downplaying the role of anesthesiologists in longitudinal patient care, there is no consensus for anesthesiologists to recommend postoperative primary care blood pressure follow-up for patients presenting for surgery with an increased blood pressure. The decision of whom to refer should ideally be based on a predictive model that balances performance with ease-of-use. If an acceptable decision rule was developed, a new practice paradigm integrating the surgical encounter into broader public health efforts could be tested, with the goal of reducing long-term morbidity from hypertension among surgical patients. ⋯ In a national cohort of surgical patients, poorly controlled postoperative clinic blood pressure was present in >1 of 4 patients (95% CI, 25.5%-25.9%). Predictive modeling based on the mean of 2 preoperative blood pressure measurements performed nearly as well as more complicated models and may provide acceptable predictive performance to guide postoperative referral decisions. Future studies of the feasibility and efficacy of such referrals are needed to assess possible beneficial effects on long-term cardiovascular morbidity.

The Analgesic Effect of Rolipram, a Phosphodiesterase 4 Inhibitor, on Chemotherapy-Induced Neuropathic Pain in Rats.
Chemotherapy-induced neuropathic pain is a significant side effect of chemotherapeutic agents. Currently, there are no effective analgesics for chemotherapy-induced neuropathic pain. Rolipram is a selective phosphodiesterase 4 inhibitor, which increases intracellular cyclic AMP in nerve and immune cells. The aim of our study was to determine the analgesic effects of rolipram on paclitaxel (PAC)-induced neuropathic pain in rats. ⋯ These results suggest that rolipram alleviated mechanical allodynia induced by PAC in rats. Thus, phosphodiesterase 4 inhibitors may prove useful in the treatment of chemotherapy-induced neuropathic pain. However, further studies are needed to clarify their effects in clinical settings.

Observational StudyExtravascular Lung Water and Pulmonary Vascular Permeability Index Measured at the End of Surgery Are Independent Predictors of Prolonged Mechanical Ventilation in Patients Undergoing Liver Transplantation.
Pulmonary edema (PE) after orthotopic liver transplantation (OLT) may compromise the postoperative course and prolong the duration of mechanical ventilation (MV) and intensive care unit length of stay. Hemodynamic monitoring with transpulmonary thermodilution permits quantification of extravascular lung water index (ELWI) and calculation of the pulmonary vascular permeability index (PVPI), which is the ratio between the ELWI and the pulmonary blood volume. This ratio can discriminate between PE hydrostatic and nonhydrostatic PE. We investigated the relationship between ELWI and PVPI values, measured at the end of surgery, and prolonged MV (PMV) in patients after OLT. ⋯ PVPI and ELWI values obtained at the end of OLT are useful for predicting the need for postoperative PMV.

Ebola virus, the virus responsible for Ebola virus disease, has spawned several epidemics during the past 38 years. In 2014, an Ebola epidemic spread from Africa to other continents, becoming a pandemic. The virus's relatively unique structure, its infectivity and lethality, the difficulty in stopping its spread, and the lack of an effective treatment captured the world's attention. This article provides a brief review of the known history of Ebola virus disease, its etiology, epidemiology, and pathophysiology and a review of the limited information on managing patients with Ebola virus disease.
