RESUMEN
BACKGROUND: Stillbirth is frequently the result of pathological processes involving the placenta. Understanding the significance of specific lesions is hindered by qualitative subjective evaluation. We hypothesised that quantitative assessment of placental morphology would identify alterations between different causes of stillbirth and that placental phenotype would be independent of post-mortem effects and differ between live births and stillbirths with the same condition. METHODS: Placental tissue was obtained from stillbirths with an established cause of death, those of unknown cause and live births. Image analysis was used to quantify different facets of placental structure including: syncytial nuclear aggregates (SNAs), proliferative cells, blood vessels, leukocytes and trophoblast area. These analyses were then applied to placental tissue from live births and stillbirths associated with fetal growth restriction (FGR), and to placental lobules before and after perfusion of the maternal side of the placental circulation to model post-mortem effects. RESULTS: Different causes of stillbirth, particularly FGR, cord accident and hypertension had altered placental morphology compared to healthy live births. FGR stillbirths had increased SNAs and trophoblast area and reduced proliferation and villous vascularity; 2 out of 10 stillbirths of unknown cause had similar placental morphology to FGR. Stillbirths with FGR had reduced vascularity, proliferation and trophoblast area compared to FGR live births. Ex vivo perfusion did not reproduce the morphological findings of stillbirth. CONCLUSION: These preliminary data suggest that addition of quantitative assessment of placental morphology may distinguish between different causes of stillbirth; these changes do not appear to be due to post-mortem effects. Applying quantitative assessment in addition to qualitative assessment might reduce the proportion of unexplained stillbirths.
RESUMEN
BACKGROUND: Telemedicine holds great potential to improve access to care and to reduce barriers to treatment for military populations with posttraumatic stress disorder (PTSD). This study sought to integrate the use of telemedicine mental health treatment services by a community healthcare provider to military populations residing in a rural location and to compare the equivalency of cognitive behavioral therapy (CBT) administered via telemedicine and traditional face-to-face therapy. SUBJECTS AND METHODS: Study subjects were men or women 18 years of age or older who had served in Operation Enduring Freedom (OEF) and/or Operation Iraqi Freedom (OIF) and were diagnosed with PTSD. The 18 study subjects were randomized and provided 10 weekly therapy sessions of CBT. Pre- and post-intervention assessments were conducted using the Clinician Administered PTSD Scale (CAPS), Hamilton Anxiety Rating Scale (HAM-A), Montgomery-Asberg Depression Rating Scale (MADRS), Life Events Checklist, and SF-36v2® (QualityMetric, Lincoln, RI) Health Survey. RESULTS: The CAPS, HAM-A, and MADRS each demonstrated lower scores, signifying improvement, and 69% of subjects experienced a clinically significant change in the CAPS. Patient satisfaction results indicated greater satisfaction for telemedicine as opposed to traditional face-to-face treatment. CONCLUSIONS: Findings reveal a trend expressing the equivalence of telemedicine and face-to-face therapy when treating OEF/OIF veterans with PTSD among rural populations by a community provider. It further demonstrates the successful collaboration between a community healthcare provider and the military healthcare system.
