RESUMO

OBJECTIVES: Epidural analgesia is frequently used to alleviate postoperative pain. Though rare, epidural hematoma continues to be a feared complication of neuraxial analgesia. The risk of epidural hematoma is likely increased when certain regimens are used for prophylaxis/treatment of venous thromboembolism. To help decrease the risk, we developed an alert in our electronic medical record to assist providers with adherence to published guidelines addressing neuraxial analgesia and anticoagulation. METHODS: Patient data were collected retrospectively 3 months before and 3 months after the initiation of the computerized alert to assess the effectiveness of the alert. Patients were included if they had a procedure code associated with epidural analgesia. Pregnant patients and children were excluded. Type and frequency of antithrombotic medications were recorded for comparison to published practice guidelines. RESULTS: Using Poisson regression to describe the data, patients with epidurals after the best practice alert observed a 61% decrease in the expected number of days of exposure to inappropriate doses of anticoagulation versus patients treated before implementation of the alert. CONCLUSION: Unapproved antithrombotic administration was significantly reduced after initiation of the alert system. This simple electronic alert was found to have a protective effect for patients receiving both anticoagulation and epidural analgesia.

RESUMO

Inhaled diacetyl vapors are associated with flavorings-related lung disease, a potentially fatal airway disease. The reactive α-dicarbonyl group in diacetyl causes protein damage in vitro. Dicarbonyl/l-xylulose reductase (DCXR) metabolizes diacetyl into acetoin, which lacks this α-dicarbonyl group. To investigate the hypothesis that flavorings-related lung disease is caused by in vivo protein damage, we correlated diacetyl-induced airway damage in mice with immunofluorescence for markers of protein turnover and autophagy. Western immunoblots identified shifts in ubiquitin pools. Diacetyl inhalation caused dose-dependent increases in bronchial epithelial cells with puncta of both total ubiquitin and K63-ubiquitin, central mediators of protein turnover. This response was greater in Dcxr-knockout mice than in wild-type controls inhaling 200 ppm diacetyl, further implicating the α-dicarbonyl group in protein damage. Western immunoblots demonstrated decreased free ubiquitin in airway-enriched fractions. Transmission electron microscopy and colocalization of ubiquitin-positive puncta with lysosomal-associated membrane proteins 1 and 2 and with the multifunctional scaffolding protein sequestosome-1 (SQSTM1/p62) confirmed autophagy. Surprisingly, immunoreactive SQSTM1 also accumulated in the olfactory bulb of the brain. Olfactory bulb SQSTM1 often congregated in activated microglial cells that also contained olfactory marker protein, indicating neuronophagia within the olfactory bulb. This suggests the possibility that SQSTM1 or damaged proteins may be transported from the nose to the brain. Together, these findings strongly implicate widespread protein damage in the etiology of flavorings-related lung disease.

RESUMO

Limited research exists on sexually transmitted infection (STI) and risk behaviour among military personnel. Published research on condom use and types of contraceptives used yield mixed results, yet, the perception that military members are at higher risk for STIs remains. The objectives of this cross-sectional study were to measure factors such as condom use, contraceptive methods, and risky behaviours (i.e. drug use and sex with commercial sex workers) and investigate differences between ethnic groups, where culture could influence behaviour. Data were collected from a recruited population of 584 male, military conscripts in northeastern Europe. Using multinomial logistic regression models, statistically significant findings include an interaction between the use of contraceptive methods of Russians with casual partners and ethnicity, with higher odds of effective methods used among Estonians with regular partners (OR = 8.13) or casual partners (OR = 11.58) and Russians with regular partners (OR = 4.98). Effective contraceptive methods used less frequently with casual partners by ethnic Russians is important in providing education and risk reduction services to young, male conscripts. These findings may be used as a baseline to inform health education and STI prevention programmes tailored to military members in Eastern Europe in the absence of other published studies.
