Bioimpedance cardiography in pregnancy: A longitudinal cohort study on hemodynamic pattern and outcome
Background: Pregnancy associated cardiovascular pathologies have a significant impact on outcome for mother
and child. Bioimpedance cardiography may provide additional outcome-relevant information early in pregnancy
and may also be used as a predictive instrument for pregnancy-associated diseases.
Methods: We performed a prospective longitudinal cohort trial in an outpatient setting and included 242 pregnant
women. Cardiac output and concomitant hemodynamic data were recorded from 11th-13th week of gestation
every 5th week as well as at two occasions post partum employing bioimpedance cardiography.
Results: Cardiac output increased during pregnancy and peaked early in the third trimester. A higher heart rate
and a decreased systemic vascular resistance were accountable for the observed changes. Women who had a
pregnancy-associated disease during a previous pregnancy or developed hypertension or preeclampsia had a
significantly increased cardiac output early in pregnancy. Furthermore, an effect of cardiac output on birthweight
was found in healthy pregnancies and could be confirmed with multiple linear regression analysis.
Conclusions: Cardiovascular adaptation during pregnancy is characterized by distinct pattern described herein.
These may be altered in women at risk for preeclampsia or reduced birthweigth. The assessment of cardiac
parameters by bioimpedance cardiography could be performed at low costs without additional risks
Definitive radiotherapy and Single-Agent radiosensitizing Ifosfamide in Patients with localized, irresectable Soft Tissue Sarcoma: A retrospective analysis
<p>Abstract</p> <p>Background and Purpose</p> <p>Standard therapy for soft-tissue sarcomas remains complete resection. For primary radiotherapy local control rates of 30-45% have been reported. We analyzed retrospectively 11 cases of radiochemotherapy with single-agent ifosfamide in patients with macroscopic soft-tissue sarcomas.</p> <p>Patients and Methods</p> <p>The patients were treated in irresectable high risk situations. Radiation therapy was performed with median 60 Gy. During the first and fifth week the concomitant chemotherapy with ifosfamide was added. Two patients received trimodal therapy with additional regional hyperthermia.</p> <p>Results</p> <p>The therapy was completed in 73% of the patients. Average local control time was 91 months, median disease-free-survival/overall-survival was 8/26 months. Five-year rates for local control/disease free survival/overall survival were 70%/34%/34%. The limited prognosis is mainly caused by systemic treatment failure.</p> <p>Conclusions</p> <p>The data strongly suggest a better outcome of radiochemotherapy with ifosfamide compared to radiotherapy alone and radiotherapy in combination with other radiosensitizers.</p
