Neonatal Encephalopathy: Need for Recognition of Multiple Etiologies for Optimal Management
Neonatal encephalopathy (NE) is associated with high mortality and morbidity. Factors predisposing to NE can be antenatal, perinatal, or a combination of both. Antenatal maternal factors, familial factors, genetic predisposition, hypoxic ischemic encephalopathy, infections, placental abnormalities, thrombophilia, coagulation defects, and metabolic disorders all have been implicated in the pathogenesis of NE. At present, therapeutic hypothermia is the only treatment available, regardless of etiology. Recognizing the etiology of NE involved can also guide investigations such as metabolic and sepsis workups to ensure optimal management. Understanding the etiology of NE may allow the development of targeted adjunctive therapies related to the underlying mechanism and develop preventative strategies
Is antenatal screening for syphilis still necessary?
Congenital syphilis continues to present a significant public health problem worldwide. The cornerstone of prevention of congenital syphilis is antenatal screening and treatment of affected mothers with penicillin. If untreated, symptoms develop within weeks or months. Early congenital syphilis occurs in children between 0 and 2 years old, however newborns may be asymptomatic and are only identified on routine screening. If such infants are missed and untreated, they can develop late congenital syphilis after 2 years. Syphilis is known as the âGreat Imitatorâ and congenital syphilis can present as neurosyphilis, juvenile paresis, optic atrophy, blindness, progressive sensorineural deafness, dental and skeletal abnormalities

Fluidity of Equipoise in a Multi-Centred Pilot RCT:Influences on Clinician Decision-Making in Offering Trial Entry
Objectives: The embedded Qualitative Process Evaluation (QPE) within the CSTICH- Pilot RCT explored facilitators and barriers to recruitment within the Pilot. This study reports a secondary analysis of the overarching theme of Fluidity of Equipoise and the influences on individual and community clinical equipoise around the use of Emergency Cervical Cerclage (ECC). Study design: RCT recruitment assumes clinical equipoise and is defined as genuine uncertainty about an intervention. The ability of trial recruiters to convey this equipoise is also key to participant recruitment and fully informed consent. This exploratory qualitative process evaluation used semi-structured interviews with healthcare professionals (HCPs) involved in trial recruitment. Interviews were audio-recorded, transcribed, and analysed using codebook thematic analysis. Results: 23 HCPs were interviewed. Clinical equipoise around the use of ECC was variable and influenced by a multitude of factors including: (1) obstetric history; (2) gestation; (3) standard site practice, and (4) HCPs previous experiences of ECC. We have interpreted this variability as âfluidity of equipoiseâ. Conclusions: Clinical equipoise around complex pregnancy related conditions was fluid and influenced by the complexities of obstetric histories and gestation at presentation. Equipoise of HCPs involved in trial recruitment should be considered carefully as it can impact the nuances of recruitment, particularly in more challenging trials such as CSTICH-2. Study-specific documents and training can be used to increase staff and patient awareness of uncertainty in the evidence base for interventions under investigation. Further research is needed around the potential consequences of equipoise fluidity
A phenomenological exploration of parenting after birth trauma : mothersâ perceptions of the first year
Problem
While perinatal mental health issues are considered to have an impact on a motherâs parenting capacity, there is limited research exploring mothersâ perceptions of their relationship with their child following traumatic birth experiences and how these might affect their parenting capacity.
Background
Birth trauma is a well-recognised phenomenon which may result in ongoing physical and perinatal mental health difficulties for women. This may impact on their attachment to their children, their parenting capabilities, and their self-identity as mothers.
Aims
To explore maternal self-perceptions of bonding with their infants and parenting experiences following birth trauma.
Methods
In-depth interviews with ten mothers were undertaken using an Interpretative Phenomenological Analysis methodology.
Findings
Women who experienced birth trauma often described disconnection to their infants and lacking confidence in their parental decision making. Many perceived themselves as being ânot good enoughâ mothers. For some women the trauma resulted in memory gaps of the immediate post-partum period which they found distressing, or physical recovery was so overwhelming that it impacted their capabilities to parent the way they had imagined they would. Some women developed health anxiety which resulted in an isolating experience of early parenthood.
Conclusions
Women who have suffered birth trauma may be at risk of increased fear and anxiety around their childâs health and their parenting abilities. Some women may experience this as feeling a lower emotional attachment to their infant. Women who experience birth trauma should be offered support during early parenting. Mother-Infant relationships often improve after the first year

Management of Multi Organ Dysfunction in Neonatal Encephalopathy.
Neonatal Encephalopathy (NE) describes neonates with disturbed neurological function in the first post-natal days of life. NE is an overall term that does not specify the etiology of the encephalopathy although it often involves hypoxia-ischaemia. In NE, although neurological dysfunction is part of the injury and is most predictive of long-term outcome, these infants may also have multiorgan injury and compromise, which further contribute to neurological impairment and long-term morbidities. Therapeutic hypothermia (TH) is the standard of care for moderate to severe NE. Infants with NE may have co-existing immune, respiratory, endocrine, renal, hepatic, and cardiac dysfunction that require individualized management and can be impacted by TH. Non-neurological organ dysfunction not only has a negative effect on long term outcome but may also influence the efficacy of treatments in the acute phase. Post resuscitative care involves stabilization and decisions regarding TH and management of multi-organ dysfunction. This management includes detailed neurological assessment, cardio-respiratory stabilization, glycaemic and fluid control, sepsis evaluation and antibiotics, seizure identification, and monitoring and responding to biochemical and coagulation derangements. The emergence of new biomarkers of specific organ injury may have predictive value and improve the definition of organ injury and prognosis. Further evidence-based research is needed to optimize management of NE, prevent further organ dysfunction and reduce neurodevelopmental impairment
Coagulation profiles are associated with early clinical outcomes in neonatal encephalopathy
Introduction: Neonatal encephalopathy (NE) is associated with coagulation abnormalities. We aimed to investigate the serial alterations in coagulation profiles in term infants with NE and correlate with their clinical outcomes. This was a prospective cohort study in a tertiary referral, university-affiliated maternity hospital. Neonates exposed to perinatal asphyxia were recruited (n = 82) and 39 received therapeutic hypothermia. Infants had serial coagulation tests including platelets, prothrombin time (PT), activated partial thromboplastin time (aPTT) and fibrinogen in the first week of life. The main outcome measures included MRI brain and EEG seizures. Our results show that mortality was predicted on day 1 by decreased Fibrinogen (AUC = 0.95, p = 0.009) and by PT on day 2 with a cutoff of 22 s. An abnormal MRI was predicted by Fibrinogen on day 3 with a cut-off value of 2 g/L. For prediction of grade II/III NE, PT on day 2 of life was strongest with a cut-off value of 14 s. Only elevated APTT levels on day 1 of life were predictive of seizures (AUC = 0.65, p = 0.04). Conclusion: Coagulation parameters are strong predictors of outcomes such as abnormal NE grade, seizures, and mortality
The acceptability of emergency cervical cerclage within a randomised controlled trial for cervical dilatation with exposed membranes at 16â27 + 6 weeks gestation : findings from a qualitative process evaluation of the C-STICH2 pilot trial
Objective
C-STICH2 is a randomised controlled trial of emergency cervical cerclage (ECC) vs routine care in women who present in pregnancy with premature cervical dilatation and exposed unruptured fetal membranes. Within the proposed trial an internal pilot was performed with an embedded qualitative process evaluation (QPE) to explore the feasibility of recruitment. The QPE aimed to collect and analyse data exploring the experiences of health care professionals (HCPs) involved in recruitment, and women approached about the trial.
Methods
Semi-structured interviews (telephone or face-to-face) were held with eligible participants who had consented to participate in the QPE. Interviews were audio-recorded, transcribed, and analysed to identify main themes. Interview transcripts were analysed using qualitative thematic analysis (QTA).
Results
11 women and 23 HCPs were interviewed. Three super-ordinate themes of Fluidity of Equipoise, A Complex Obstetric History, and the Influence of Gestation were identified. Within these, the five main themes which influenced trial participation were: 1) Complex decision-making processes; 2) Predicting outcomes; 3) The importance of terminology and initial RCT approach; 4) Womenâs understanding of the need for research in this area; 5) Changes in practice which are trial influenced.
Conclusions
For both HCPs and women and their families, there was a conflation of the potential risks and outcomes of ECC with those of elective cerclage and the complexity around ECC placement was not always well understood by those with less experience and understanding of the intervention. Decision making was shown to be complex and multi-factorial for both HCPs and women. For complex trials in rare conditions with treatment uncertainty, clinical equipoise is likely to be fluid and influenced by multiple factors
Investigating Genetic Determinants of Plasma Inositol Status in Adult Humans
BACKGROUND: Myo-inositol (MI) is incorporated into numerous biomolecules, including phosphoinositides and inositol phosphates. Disturbance of inositol availability or metabolism is associated with various disorders, including neurological conditions and cancers, while supplemental MI has therapeutic potential in conditions such as depression, polycystic ovary syndrome and congenital anomalies. Inositol status may be influenced by diet, synthesis, transport, utilisation and catabolism. OBJECTIVES: We aimed to investigate potential genetic regulation of circulating MI status and to evaluate correlation of MI concentration with other metabolites. METHODS: Gas chromatography mass spectrometry was used to determine plasma MI concentration of more than 2,000 healthy, young adults (aged 18-28 years) from the Trinity Student Study. Genotyping data was used to test association of plasma MI with SNPs in candidate genes, encoding inositol transporters and synthesising enzymes, and test for genome-wide association. We evaluated potential correlation of plasma MI with D-chiro inositol, glucose and other metabolites by Spearman's rank correlation. RESULTS: Mean plasma MI showed a small but significant difference between males and females (28.5 and 26.9 ”M, respectively). Candidate gene analysis revealed several nominally significant associations with plasma MI, most notably for SLC5A11, encoding a sodium-coupled inositol transporter, also known as SMIT2 (sodium-dependent myo-inositol transporter 2). However, these did not survive correction for multiple testing. Subsequent testing for genome-wide association with plasma MI did not identify associations of genome-wide significance (p < 5 Ă 10-8). However, 8 SNPs exceeded the threshold for suggestive significant association with plasma MI concentration (p < 1 Ă 10-5), 3 of which were located within or close to genes: MTDH, LAPTM4B and ZP2. We found significant positive correlation of plasma MI concentration with concentration of D-chiro-inositol and several other biochemicals including glucose, methionine, betaine, sarcosine and tryptophan. CONCLUSION: Our findings suggest potential for modulation of plasma MI in young adults by variation in SLC5A11 which is worthy of further investigation
