“Background. HM781-36B mouse Cyclic recruitment and derecruitment (R/D) play a key role in the pathomechanism of acute lung injury (ALI)

leading to respiration-dependent oscillations of arterial partial pressure of oxygen (Pa-O2). These Pa-O2 oscillations could also be forwarded to the cerebral microcirculation.\n\nMethods. In 12 pigs, partial pressure of oxygen was measured in the thoracic aorta (Pa-O2) and subcortical cerebral tissue (Pbr(O2)). Cerebral cortical haemoglobin oxygen saturation (Sbr(O2)), cerebral blood flow (CBF), and peripheral haemoglobin saturation (Sp(O2)) were assessed by spectroscopy and laser Doppler flowmetry. Measurements at different fractions of inspired oxygen (FIO2) were performed at baseline and during cyclic R/D. Statistics: frequency domain analysis, the Mann-Whitney test, linear models to test the influence of Pa-O2 and systolic arterial pressure (SAP) oscillations on cerebral measurements.\n\nResults. Parameters [mean (SD)] remained stable during baseline. Pa-O2 oscillations [10.6 (8) kPa, phase(reference)], systemic arterial pressure (SAP) oscillations [20 (9) mm Hg, phase(PaO2-SAP)-33 (72)degrees], and Sp(O2) oscillations [1.9 (1.7)%, phase(PaO2-SpO2) 264 (72)degrees] were detected during lung R/D at FIO2 1.0. Pa-O2 oscillations decreased [2.7 (3.5)

kPa, P=0.0008] and Sp(O2) oscillations increased [6.8 (3.9)%, P=0.0014] at FIO2 0.3. In the brain, synchronized Pbr(O2) oscillations [0.6 (0.4) kPa, phase(PaO2-PbrO2) 90 (39)degrees], Cilengitide Sbr(O2) oscillations [4.1 (1.5)%, phase(PaO2-SbrO2) 182 (54)degrees], and CBF oscillations [198 (176) AU, phase(PaO2-CBF) 201 (63)degrees] occurred that were dependent on Pa-O2 and SAP oscillations.\n\nConclusions. Pa-O2 oscillations caused by cyclic R/D are transmitted

to the cerebral microcirculation in a porcine model of ALI. These cyclic oxygen alterations could play a role in the crosstalk of acute lung and brain injury.”
“As patients near the end of life, bereaved family members provide an important source of evaluation of the care they receive. A study was conducted to identify which processes of care were associated with greater satisfaction with hospice services from the perception of bereaved family members. A total of 116,974 surveys from 819 hospices Screening Library in vivo in the United States were obtained via the 2005 Family Evaluation of Hospice Care, an online repository of surveys of bereaved family members’ perceptions of the quality of hospice care maintained by the National Hospice and Palliative Care Organization. Overall satisfaction was dichotomized as “excellent” vs. “other” (very good, good, fair, and poor). Using multivariate logistic regression, the association between overall satisfaction and the individual item problem scores that compose the Family Evaluation of Hospice Care were examined.
