β-human chorionic gonadotropin (HCG) level is not a reliable marker for early identification of persistent gestational trophoblastic neoplasia (GTN) after evacuation of hydatidiform mole. Thus, this study was conducted to evaluate β-HCG regression after evacuation as a predictive factor of malignant GTN in complete molar pregnancy. Methods. In this cross-sectional study, we evaluated a total of 260 patients with complete molar pregnancy. Sixteen of the 260 patients were excluded. Serum levels of HCG were measured in all patients before treatment and after evacuation. HCG level was measured weekly until it reached a level lower than 5 mIU/mL. Results. The only predictors of persistent GTN are HCG levels one and two weeks after evacuation. The cut-off point for the preevacuation HCG level was 6000 mIU/mL (area under the curve, AUC, 0.58; sensitivity, 38.53%; specificity, 77.4%), whereas cut-off points for HCG levels one and two weeks after evacuation were 6288 mIU/mL (AUC, 0.63; sensitivity, 50.46%; specificity, 77.0%) and 801 mIU/mL (AUC, 0.80; sensitivity, 79.82%; specificity, 71.64%), respectively. Conclusion. The rate of decrease of HCG level at two weeks after surgical evacuation is the most reliable and strongest predictive factor for the progression of molar pregnancies to persistent GTN.

Four binary charge-transfer complexes were made using pyromellitic acid dianhydride (pmda), those being pmda-naphthalene (1/1), C10H2O6·C10H8, (I), pmda-fluoranthene (1/1), C10H2O6·C16H10, (II), pmda-9-methylanthracene (1/1), C10H2O6·C15H12, (III), and pmda-ethyl anthracene-9-carboxylate (1/2), C10H2O6·2C17H12O3, (IV). All charge-transfer complexes show alternating donor and acceptor stacks, which have weak C?H?O hydrogen bonds connecting the donor and acceptor molecules. In addition, complex (I) has Z′ = 1/2, complex (II) has a Z′ = 2 and complex (IV) has half molecule of pyromellitic acid dianhydride in the asymmetric unit.

Background and Aim: Patients could leave ED not receiving the desired care either Without Being Seen by a doctor (LWBS) or Against Medical Advice (DAMA). In term of care quality, LWBS may be related to inappropriate access and process of care, while DAMA may lead to increased risk of mortality and re-admissions. This study aims to identify frequency of patients who leave ED, determine their characteristics and identify associated factor. Methods: This was a retrospective observational study of patients that attended EDs of University Hospital Trust of Verona in 2017. Demographic and ED access associated variables were collected for LWBS, DAMA and completed-ED-treatment patients. Univariate and multivariate data analyses was based on EMUR-PS administrative data.Results: 5,901 of 127,180 ED accesses were uncompleted treatment (4.64%); LWBS were 4,664 (79.04%) and DAMA 1,237 (20.96%). Those who leave ED tended to be younger (39.35 vs. 45.56, p<0.01). Independent factors associated with ED leaving resulted: i) non-urgent triage category (OR: 2.941, 95%CI: 2.405-3.596) ii) non-Italian-nationality (OR: 1.695, 95%CI: 1.493-1.924) and requiring psychiatric consult (OR:6.16 95%IC 4.82-7.87); while protective factors resulted: i) female gender (OR: 0.713, 95%CI: 0.633-0.803); i) Paediatric ED (OR: 0.593, 95%CI: 0.437-0.805); ii) Obstetrics-Gynaecology ED (OR: 0.284, 95%CI: 0.193-0.416) iii) inclusion in fast track pathways (OR: 0.747, 95%CI: 0.602-0.927). Higher ED leaving rate were observed during night-time and Sunday, either overcrowding resulted not associated.Conclusion: Results show the necessity to implement primary care-ED integrated pathway, mainly in frail sub-population, improve awareness on healthcare service use and refine communication skills in ED-team.
