    Abstract Background: Obstructive sleep apnea (OSA) affects approximately 20% of US adults, of whom about 90% are undiagnosed. While OSA may increase risk of perioperative complications, its prevalence among surgical patients is unknown. We tested the feasibility of screening surgical patients for OSA and determined the prevalence of undiagnosed OSA.
    Methods: In a prospective, observational study adult surgical patients were screened for OSA in an academic hospital. Patients without an OSA diagnosis who screened high-risk were offered a home sleep study to determine if they had OSA. The results were compared with polysomnography (PSG) when available. Charts of high-risk patients were examined for postoperative complications. High-risk patients received targeted interventions as part of a hospital safety initiative.
    Results: There were 2877 patients screened; 661 (23.7%) screened high-risk for OSA, of whom 534 (81%) did not have diagnosed OSA. The portable sleep study detected OSA in 170/207 (82%) high-risk patients without diagnosed OSA. Twenty-six PSGs confirmed OSA in 19 of these patients. Postoperatively there were no respiratory arrests, two unanticipated ICU admissions, and five documented respiratory complications.
    Conclusion: Undiagnosed OSA is prevalent in adult surgical patients. Implementing universal screening is feasible and can identify undiagnosed OSA in many surgical patients. Further investigation is needed into perioperative complications and their prevention for patients with undiagnosed OSA.

  3. Artikel: Phytotoxicity in Bush Bean of Five Sulfur-Containing Gases Released from Advanced Fossil Energy Technologies

    Abstract Sulfur-containing gases including sulfur dioxide (SO2), hydrogen sulfide (H2S), carbon disulfide (CS2), carbonyl sulfide (COS), and methyl mercaptan (CH3SH) are a major class of atmospheric emissions from advanced fossil energy technologies. Although phytotoxicity data for SO2 and H2S exist, the influence on vegetation of the remaining S gases is not known. This study was designed to address the comparative toxicity of the five gases in bush bean (Phaseolus vulgaris). Seedlings were exposed to each gas individually for 6 hr at a range of concentrations (6–82 μmol m−3) in an open gaseous exchange system, during which whole-plant net photosynthesis and transpiration were monitored. At the highest exposure levels, leaf necrosis was assessed 3 d after exposure. Transpiration did not respond consistently to any of the treatments. Neither CS2 nor CH3SH caused any change in photosynthesis or foliar necrosis. Based on the inhibition of photosynthesis and the development of leaf necrosis at equivalent volumetric concentrations in the atmosphere, the toxicity of the remaining three gases was SO2 > H2S > COS. The relationship between net photosynthesis and exposure dosage (concentration × time) for H2S, SO2, and COS was curvilinear and biphasic, exhibiting in each gas an enhancement of photosynthesis followed by inhibition as the dosage increased. For projected emission rates from advanced fossil energy facilities, the results suggest that releases of CH3SH and CS2 are not likely to influence vegetation. Since plant response to H2S, SO2, and COS is strongly dosage dependent, accurate estimates of field effects due to these three gases must await more adequate air quality modeling near commercial-scale facilities.

    Abstract Transport und Verteilung von Schwermetallen im Boden und in Vegetation wurden experimentell untersucht. Aus einem Waldgebiet nahe Oak Ridge, Tennessee wurden Bodensektionen entnommen mit jeweils einem Rotahorn (Acer rubrum) mit annaehernd 2 m Hoehe und Vegetations-Unterwuchs, die anschliessend in Holzgefaesse gesetzt wurden. Forstabfall eines kontaminierten Waldes und mittels Filterhaus abgeschiedener Staub aus einer Bleihuette wurde drei Versuchseinheiten appliziert, drei weitere Versuchseinheiten dienten als Kontrolle. Die gesamte Expositionskonzentration lag fuer Pb bei 11,0 Milligramm/cm2, fuer Cd bei 0,128 Milligramm/cm2, fuer Zn bie 0,748 Milligramm/ /cm2 und fuer Cn bei 0,161 Milligramm/cm2. Die Untersuchungen wurden mit dem Ziel durchgefuehrt, Transport und Assimilation der Schwermetalle und ihre Auswirkungen auf Prozesse des Naehrstoff- und Kohlenstoffkreislaufes zu bestimmen sowie die Versuchsergebnisse mit Untersuchungsergebnissen von einem Waldgebiet im Suedosten von Missouri (Crooked Creek Watersched) zu vergleichen.
