- Objective. To study the effect of the amniotic fluid quantity of Ureaplasma urealyticum DNA on inflammatory response levels in women with preterm labor (PTL) and preterm prelabor rupture of membranes (pPROM). Design. A prospective multi-center follow up study. Setting. Sahlgrenska University Hospital, Goteborg, Sweden and Turku University Hospital, Turku, Finland. Sample. Eleven U. urealyticum positive samples obtained after transabdominal amniocenteses in 197 women presenting with PTL and pPROM. Methods. The U. urealyticum positive samples were analyzed with real-time polymerase chain reaction, using the Lightcycler instrument with primers specific for U. urealyticum 16 S rDNA. The amniotic fluid samples were analyzed for tumor necrosis factor (TNF)-alpha, interleukin (IL)-6, IL-1beta and IL-10 with enzyme-linked immunosorbent assays. Main outcome measures. Correlation between U. urealyticum DNA concentrations in the amniotic fluid and inflammatory cytokine levels. Results. The concentrations of U. urealyticum DNA varied between 0.024 and 934microg/mL. A significant correlation between U. urealyticum DNA and TNF-alpha level was observed. No correlation with the other cytokines was found. Women with PTLhad higher levels of U. urealyticum DNA and a different cytokine pattern than women with pPROM. Conclusions. U. urealyticum in the amniotic fluid induces an inflammatory reaction in a dose dependent manner and the quantity of U. urealyticum DNA is well correlated with the level of the inflammatory cytokine TNF-alpha.

RESULTS: The concentrations of U. urealyticum DNA varied between 0.024 and 934 microg/mL. A significant correlation between U. urealyticum DNA and TNF-alpha level was observed. No correlation with the other cytokines was found. Women with PTLhad higher levels of U. urealyticum DNA and a different cytokine pattern than women with pPROM. CONCLUSIONS: U. urealyticum in the amniotic fluid induces an inflammatory reaction in a dose dependent manner and the quantity of U. urealyticum DNA is well correlated with the level of the inflammatory cytokine TNF-alpha.

Targets for improving dispatcher identification of acute stroke

- Background: Accurate identification of acute stroke by Emergency Medical Dispatchers (EMD) is essential for timely and purposeful deployment of Emergency Medical Services (EMS), and a prerequisite for operating mobile stroke units. However, precision of EMD stroke recognition is currently modest. Aims: We sought to identify targets for improving dispatcher stroke identification. Methods: Dispatch codes and EMS patient records were cross-linked to investigate factors associated with an incorrect dispatch code in a prospective observational cohort of 625 patients with a final diagnosis of acute stroke or transient ischemic attack (TIA), transported to our stroke center as candidates for recanalization therapies. Call recordings were analyzed in a subgroup that received an incorrect low-priority dispatch code indicating a fall or unknown acute illness (n = 46). Results: Out of 625 acute stroke/TIA patients, 450 received a high-priority stroke dispatch code (sensitivity 72.0%; 95% CI, 68.5-75.5). Independent predictors of dispatcher missed acute stroke included a bystander caller (aOR, 3.72; 1.48-9.34), confusion (aOR, 2.62; 1.59-4.31), fall at onset (aOR, 1.86; 1.24-2.78), and older age (aOR [per year], 1.02; 1.01-1.04). Of the analyzed call recordings, 71.7% revealed targets for improvement, including failure to recognize a Face Arm Speech Time (FAST) test symptom (21/46 cases, 18 with speech disturbance), or failure to thoroughly evaluate symptoms (12/46 cases). Conclusions: Based on our findings, efforts to improve dispatcher stroke identification should primarily focus on improving recognition of acute speech disturbance, and implementing screening of FAST-symptoms in emergency phone calls revealing a fall or confusion.
