M-EA (methotrexate, etoposide, dactinomycin) and EMA-CO (methotrexate, etoposide, dactinomycin / cyclophosphamide, vincristine) regimens as first-line treatment of high-risk gestational trophoblastic neoplasia.

High-risk gestational trophoblastic neoplasia (GTN) is highly chemosensitive with an excellent prognosis with treatment. Historically in the United Kingdom, the high-risk regimens used have been M-EA (methotrexate, etoposide, dactinomycin) (Sheffield) and EMA-CO (methotrexate, etoposide, dactinomycin / cyclophosphamide, vincristine) (Charing Cross, London) with prior published data suggesting no difference in survival between these. Our Sheffield treatment policy changed in 2014, switching from M-EA to EMA-CO, aiming to reduce time in hospital, and harmonise UK practice. We aimed to report the toxicities, response rates and survival outcomes for 79 patients with high-risk GTN treated in the first-line setting with either M-EA (n = 59) or EMA-CO (n = 20) from 1998 to 2018. Median duration of treatment was similar (M-EA, 17.3 weeks (IQR 13.9-22.6) and 17.6 weeks (IQR 13.4-20.7) with EMA-CO. For M-EA, overall human chorionic gonadotrophin (hCG) complete response (CR) rate was 84.7% (n = 50/59). Two patients died of drug-resistant disease after several lines of multiagent chemotherapy; overall survival is 96.6% (median follow-up 10.4 years). For EMA-CO, overall hCG CR rate was 70%, overall survival is 100% (median follow-up 4 years). In our experience, patients treated with EMA-CO experienced an apparent increased incidence of neutropenia, non-neutropenic Grade 3-4 infection, peripheral neuropathy and more treatment delays and nights in hospital. Granulocyte-colony stimulating factor, after both EMA and CO arms, titrated to baseline neutrophil count improved the toxicity profile. Both treatment regimens are associated with excellent prognosis; selection of regimen may be further guided by individual patients' personal, social and family circumstances. There is further rationale to explore whether these regimens can be refined, such as 2-weekly EMA, to optimise patient experience and reduce toxicity while maintaining efficacy.

Improvement in primary school adherence to the NSW Healthy School Canteen Strategy in 2007 and 2010.

ISSUE ADDRESSED: Since 2005, a government-endorsed strategy guiding food sold in New South Wales school canteens has been in place. This study describes the changes in school canteen food between 2007 and 2010 and characterises schools most likely to adhere to strategy guidelines. METHODS: Menus obtained from a cohort of primary and central schools in the Hunter New England region of New South Wales were audited using a traffic light system of classification. Energy dense, nutrient-poor or 'red' items are restricted; 'amber' are to be selected carefully and healthier 'green' items are encouraged. RESULTS: In 2007, 7% of schools had no red items on their menu. In 2010, this improved to 22% (P < 0.05). In 2010, small schools (OR = 1.9, 95% CI = 1.25-3.05, P = 0.003); lower socioeconomic schools (OR = 1.3, 95% CI = 1.02-1.78, P = 0.03); non-government (OR = 1.7, 95% CI = 1.22-2.23, P = 0.001) and rural schools (OR = 1.7, 95% Cl = 1.30-2.25, P < 0.001) had higher odds of having red items on the menu. No significant change occurred in the proportion of green foods listed for sale between 2007 and 2010. CONCLUSIONS: Proportion of schools adhering to strategy guidelines had increased slightly, however, most continue to list red items for regular sale. SO WHAT? For health policies to improve public health they need implementation. Findings suggest more work is required, particularly in small schools, rural schools and non-government schools.

Placental syndecan-1 and sulphated glycosaminoglycans are decreased in preeclampsia.

Glycosaminoglycans are found in extracellular matrix and on the cell surface in the form of proteoglycans. There is evidence that these molecules regulate biological processes, including cell survival, migration and angiogenesis. Preeclampsia is a common pregnancy disorder associated with insufficient placental development. This study aimed to determine the concentrations of glycosaminoglycans and the proteoglycan syndecan-1 within villous trophoblast and to investigate changes associated with preeclampsia. Seventy-five placental samples collected from third trimester singleton pregnancies were divided into term placentas following labour onset, gestational age-matched placentas prior to labour onset and preterm placentas. Preterm placentas were divided into three gestational age-matched groups, spontaneous preterm labour, preterm premature rupture of membranes (PPROM) and preterm preeclampsia. Sulphated glycosaminoglycan (sGAG) concentrations in placental extracts were quantified using a modified 1,9-dimethylmethylene blue assay. Syndecan-1 expression was localised using immunohistochemistry and concentrations in placental extracts determined by immunoassay. Preterm placentas had significantly lower sGAG concentrations compared to term tissues and concentrations were significantly lower in preeclampsia compared to spontaneous preterm labour (medians 5.80 and 10.0 µg/mg protein respectively, P<0.05). Syndecan-1 expression was localised to syncytiotrophoblast and median concentrations were lower in preeclampsia compared to PPROM material (preeclampsia median = 41.7, PPROM 74.4 ng/mg tissue) but not significantly different to concentrations in spontaneous preterm labour. Multivariate analysis revealed that decreased sGAG and syndecan-1 in preeclampsia were independent of labour, gestational age and birthweight centile. These findings may provide insights into a role for these molecules in the pathophysiology of preeclampsia.
