INTRODUCTION It is widely debated whether fetal membranes possess a genuine microbiome, and if bacterial presence and load is linked to inflammation. Chorioamnionitis is an inflammation of the fetal membranes. This research focussed on inflammatory diagnosed histological chorioamnionitis (HCA) and aimed to determine whether the bacterial load in fetal membranes correlates to inflammatory response, including histological staging and inflammatory markers in HCA. METHODS Fetal membrane samples were collected from patients with preterm spontaneous labour and histologically phenotyped chorioamnionitis (HCA; n = 12), or preterm (n = 6) and term labour without HCA (n = 6). The bacterial profile of fetal membranes was analysed by sequencing the V4 region of the 16S rRNA gene. Bacterial load was determined using qPCR copy number/mg of tissue. The association between bacterial load and bacterial profile composition was assessed using correlation analysis. RESULTS Bacterial load was significantly greater within HCA amnion (p = 0.002) and chorion (p = 0.042), compared to preterm birth without HCA. Increased bacterial load was positively correlated with increased histological staging (p = 0.001) and the expression of five inflammatory markers; IL8, TLR1, TLR2, LY96 and IRAK2 (p= less then 0.050). Bacterial profiles were significantly different between membranes with and without HCA in amnion (p = 0.012) and chorion (p = 0.001), but no differences between specific genera were detected. DISCUSSION Inflammatory HCA is associated with infection and increased bacterial load in a dose response relationship. Bacterial load is positively correlated with HCA severity and the TLR signalling pathway. Further research should investigate the bacterial load threshold required to generate an inflammatory response in HCA. INTRODUCTION Abnormally invasive placenta (AIP, aka placenta accreta spectrum; PAS) is an increasingly common pregnancy pathology, which, despite significant morbidity risk to the mother, is often undiagnosed prior to delivery. We tested several potential biomarkers in plasma from PAS mothers to determine whether any were sufficiently robust for a formal, diagnostic accuracy study. METHODS We examined hyperglycosylated hCG (h-hCG), decorin and IL-8, based on biological plausibility and literature indications that they might be altered in PAS. These analytes were assayed by ELISA in maternal plasma from five groups, comprising (1) normal term controls, (2) placenta previa controls, and cases of (3) placenta increta/percreta without placenta previa, (4) placenta previa increta/percreta and (5) placenta previa accreta. RESULTS There were no differences in h-hCG, ß-hCG or the h-hCG/ß-hCG ratio between the groups. Adavosertib Mean decorin levels were increased in previa controls (Group 2) compared to the other groups, but there was substantial overlap between the individual values. While an initial multiplex assay showed a greater value for IL-8 in the placenta previa increta/percreta group (Group 4) compared to placenta previa controls (Group 2), the subsequent validation ELISA for IL-8 showed no differences between the groups. DISCUSSION We conclude that the absence of differences and the extent of overlap between cases and controls does not justify further assessment of these biomarkers. INTRODUCTION Chronic histiocytic intervillositis (CHI) is a placental disease that has been associated with unfavorable obstetric outcomes in small, noncomparative series. The objective was to measure the excess risk of adverse obstetric outcomes associated with the discovery of CHI after birth. METHODS Retrospective single-center case-control study from 2000 through 2016. The case patients had a CHI diagnosis after a pathology analysis of the placenta. Two types of controls were defined for each case low-risk control women were those who gave birth in our hospital immediately before each case patient, and the high-risk controls were the next women after each case for whom microscopic examination of the placenta was indicated. RESULTS We observed 111 cases of CHI during the study period. Compared with the 111 low-risk controls, the cases had a significantly higher frequency of late miscarriages (5.4 vs 0.0%, p less then .03), small for gestational age (SGA) babies less then 3rd centile (70.4 vs 0.9%, p less then .001, OR 140, 95% CI, 19.9-2800), and in utero deaths (35.1 vs 0.9%, p less then .001, OR 59.6, 95% CI 8.5-1192), with significantly fewer children surviving to discharge (54.9 vs 99.1%, p less then .001, OR 0.01, 95% CI, 0.00-0.08). All of these factors also differed significantly compared with the high-risk women (severe SGA OR 3.7, 95% CI 1.9-7.0; in utero death OR 4.1, 95% CI 1.9-8.7; children surviving to discharge OR 0.27, 95% CI, 0.14-0.52). DISCUSSION Even compared with high-risk pregnancies, CHI is a severe placental disease associated with a substantial excess rate of late miscarriages, severe SGA and in utero death. INTRODUCTION Recently, Delta-like homolog 1 (DLK1) was identified as a potential marker of small-for-gestational-age (SGA; less then 10th centile) fetuses; mouse studies suggest reduced levels may represent a fetal stress signal. We sought to measure DLK1 in a large independent cohort of maternal blood samples, correlate levels with measures of placental insufficiency and assess whether DLK1 might be placental derived. METHODS The Fetal Longitudinal Assessment of Growth (FLAG) study was a prospective blood collection from 2000 women. We assessed a case-control cohort at 28 and 36 weeks from the first 1000 FLAG women, before validating changes in the entire second 1000. A subgroup of FLAG participants underwent ultrasound examinations, and 137 neonates, body composition assessment (PEAPOD). DLK1 secretion was assessed from human placentas ex vivo. RESULTS Circulating DLK1 was significantly reduced at 28 and 36 weeks' gestation in women destined to deliver a SGA fetus and associated with birthweight centile (n = 999, p less then 0.0001), and placental weight (n = 96, p = 0.0064). Ex vivo, DLK1 was abundantly released from human placenta and significantly reduced under hypoxia (n = 7, p less then 0.05). We found no relationship between circulating DLK1 and estimated fetal weight, cerebroplacental ratio, uterine artery or umbilical artery pulsatility index. Nor was there a relationship between DLK1 and neonatal fat or lean mass (n = 137). CONCLUSION We confirmed circulating DLK1 is reduced at both 28 and 36 weeks' gestation preceding delivery of a SGA infant, shown that it is not significantly associated with clinical measures of placental insufficiency, and provide new data demonstrating it may be placenta-derived in humans. INTRODUCTION Chronic intervillositis of unknown etiology (CIUE) is a histopathological lesion of the placenta that is frequently accompanied by unfavourable pregnancy outcomes, e.g. miscarriage, fetal growth restriction (FGR) and intrauterine fetal death. Earlier described case series and cohorts have been based on diverse diagnostic criteria of CIUE. To improve our understanding of clinical outcomes associated with CIUE, we report the obstetric and perinatal outcomes in a cohort based on the recently described diagnostic criteria. METHODS CIUE is defined as an infiltrate occupying 5% or more of the intervillous space with approximately 80% of mononuclear cells positive for CD68 in the absence of an infection. Thirty-eight cases were included. Also previous and subsequent pregnancies were described. RESULTS Pregnancies accompanied by CIUE frequently resulted in FGR (51.6%) and pre-term birth (55.3%). Twenty-nine out of 38 pregnancies (76.3%) with CIUE resulted in a living baby. Women with CIUE frequently have had a miscarriage (16/38; 42%). Four-teen subsequent pregnancies in 8 women resulted in 2 miscarriages, 2 terminations of pregnancy for FGR, 1 early neonatal death and 9 living babies (9/14; 64.3%). Histopathologically confirmed CIUE recurred in 5 out of 10 subsequent pregnancies. Two pregnancies with recurrent CIUE were terminated, one pregnancy ended in a late miscarriage and another resulted in term birth complicated by FGR. Recurrent CIUE can also be accompanied by an uncomplicated pregnancy (1/5; 20%). CONCLUSION This study provides additional insight into the clinical phenotype of CIUE and emphasises the need for further research to understand the pathophysiology behind different pregnancy outcomes in CIUE. Ranaviruses have been associated with chelonian mortality. In Canada, the first two cases of ranavirus were detected in turtles in 2018 in Ontario, although a subsequent survey of its prevalence failed to detect additional positive cases. To confirm the prevalence of ranavirus in turtles in Ontario, we used a more sensitive method to investigate if lower level persistent infection was present in the population. Here we report results via a combination of qPCR, PCR, Sanger sequencing and genome sequencing from turtles from across Ontario, with no clinical signs of illness. We found 2 positives with high viral load and 5 positives with low viral load. Histopathology found subtle histological changes. DNA sequences identified two types of frog virus 3 (FV3), and genome sequencing identified a ranavirus similar to wild-type FV3. Our results show that the virus has been present in Ontario's turtles as subclinical infections. Viruses exploit phosphorylation of both viral and host proteins to support viral replication. In this study, we demonstrate that porcine reproductive and respiratory syndrome virus replicase nsp2, and two nsp2-related -2/-1 frameshifting products, nsp2TF and nsp2N, are hyper-phosphorylated. By mapping phosphorylation sites, we subdivide an extended, previously uncharacterized region, located between the papain-like protease-2 (PLP2) domain and frameshifting site, into three distinct domains. These domains include two large hypervariable regions (HVR) with putative intrinsically disordered structures, separated by a conserved and partly structured interval domain that we defined as the inter-HVR conserved domain (IHCD). Abolishing phosphorylation of the inter-species conserved residue serine918, which is located within the IHCD region, abrogates accumulation of viral genomic and subgenomic RNAs and recombinant virus production. Our study reveals the biological significance of phosphorylation events in nsp2-related proteins, emphasizes pleiotropic functions of nsp2-related proteins in the viral life cycle, and presents potential links to pathogenesis. BACKGROUND The children of parents with severe personality difficulties have greater risk of significant mental health problems. Existing care is poorly co-ordinated, with limited effectiveness. A specialised parenting intervention may improve child and parenting outcomes, reduce family morbidity and lower the service costs. OBJECTIVES To develop a specialised parenting intervention for parents affected by severe personality difficulties who have children with mental health problems and to conduct a feasibility trial. DESIGN A pragmatic, mixed-methods design to develop and pilot a specialised parenting intervention, Helping Families Programme-Modified, and to conduct a randomised feasibility trial with process evaluation. Initial cost-effectiveness was assessed using UK NHS/Personal Social Services and societal perspectives, generating quality-adjusted life-years. Researchers collecting quantitative data were masked to participant allocation. SETTING Two NHS mental health trusts and concomitant children's social care services.
