    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; preterm delivery; transvaginal ultrasound; cervical length measurement; second trimester; prospective study; observational study; mass screening; reproducibility of results; inter-observer variation; intra-observer variation; data accuracy; quality control;

    Sammanfattning : Abstract Background: Short cervical length is a risk factor for preterm delivery (PTD) and screening of cervical length using transvaginal ultrasound in the second trimester is a proposed method to find women at risk Aims: To examine the potential value of routine measurement of cervical length in a Swedish population of women with singleton pregnancies in the prediction of PTD. To estimate inter- and intra-observer agreement and reliability of cervical length measurements. LÄS MER

  5. 4. To See or Not to See : A Study on Capillary Refill

    Författare :Rani Toll; Chris D Anderson; Daniel Wilhelms; Joakim Henricson; Gert Nilsson; David Schriger; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Background: Assessment of the critically ill is traditionally based on vital signs (blood pressure, pulse, respiratory rate, temperature and level of consciousness). Altered vital signs are, however, late indicators of deranged hemodynamics pointing to a need for additional, more sensitive markers of circulatory compromise. LÄS MER

  7. 5. Low Back Pain : With Special Reference to Prevalence, Diagnosis, Treatment and Prognosis

    Sammanfattning : Objectives. Ascertain if there has been a secular trend in 3-months prevalence of casually reported back pain. Evaluate if such back pain predicts concurrent health as well as future sick leave, disability pension, hospitalization and survival. Study differences in diagnostic assessment and labelling between physicians. LÄS MER
