Counselling in Fetal Medicine: Uncomplicated Twin Pregnancies.

J Clin Med

December 2024

Vascular Biology Research Centre, Molecular and Clinical Sciences Research Institute, St George's University of London, London SW17 0RE, UK.

Twin pregnancies account for 3% of all pregnancies and they are burdened by higher morbidity and mortality compared to singletons. The role of ultrasound in the screening, diagnosis and management of possible complications of twin pregnancies has been widely investigated in the current literature. However, despite the progress that have been made in the last decades regarding treatment and evidence-based management of complications, twin pregnancies remain at higher risk of adverse outcomes, requiring therefore dedicated surveillance.

Twin pregnancies are at increased risk of morbidity and mortality compared to singletons. Among all twins, monochorionic pregnancies are at higher risk of specific and non-specific complications compared to dichorionic pregnancies. Therefore, it is of great importance to properly counsel future parents with monochorionic pregnancies regarding the risks of adverse outcomes and the modalities of monitoring and intervention of the potential complications.

Connected speech samples elicited by a picture description task are widely used in the assessment of aphasias, but it is not clear what their interpretation should focus on. Although such samples are easy to collect, analyses of them tend to be time-consuming, inconsistently conducted and impractical for non-specialist settings. Here, we analysed connected speech samples from patients with the three variants of primary progressive aphasia (semantic, svPPA = 9; logopenic, lvPPA = 9; and non-fluent, nfvPPA = 9), progressive supranuclear palsy (PSP Richardson's syndrome = 10), corticobasal syndrome (CBS = 13) and age-matched healthy controls ( = 24).

Patients with acute pulmonary embolism (PE) have a wide spectrum of clinical presentations, from incidental findings to sudden cardiac death. Management and treatment recommendations in currently available guidelines vary according to patient risk and haemodynamic profile. A clot-in-transit (CiT) in the right heart chambers may be occasionally identified and is, therefore, an under-recognised but challenging condition, often preceding an abrupt clinical deterioration, and associated with increased mortality.

January 2025

Department of Women and Children's Health, School of Life Course and Population Sciences, Faculty of Life Sciences and Medicine, King's College London, London, UK.

Article Synopsis
  • This study examines the effectiveness of third-trimester ultrasound in detecting small-for-gestational age (SGA) babies, highlighting concerns about low detection rates and risks associated with false results.
  • Researchers analyzed data from the DESiGN trial, focusing on stillbirth and neonatal morbidity outcomes among pregnancies classified as either false-negative, true-positive, false-positive, or true-negative for SGA.
  • Findings revealed that false-negative SGA results significantly increased the risk of stillbirth compared to true-positive diagnoses, while the implications of false-positive results were also evaluated, indicating potential risks in misclassification during antenatal screening.

Article Synopsis
  • Maternal cardiovascular changes during pregnancy are crucial for adequate placental blood flow, but hypertensive disorders of pregnancy (HDP) affect around 10% of pregnancies, leading to serious heart issues.
  • Women with HDP face long-term cardiovascular risks, including hypertension and heart disease, shortly after delivery and in the following decades.
  • There is a pressing need for standardized early cardiovascular screening for these women, but current protocols are lacking due to insufficient evidence and variations in risk related to race and health determinants.

Article Synopsis
  • Brugada syndrome (BrS) is a hereditary heart condition that raises the risk of sudden cardiac death due to dangerous heart rhythms, and catheter ablation can help reduce these risks by targeting specific areas in the heart.
  • A 66-year-old male with BrS underwent a unique catheter ablation procedure using automated frequency mapping to locate and treat problematic heart regions, showing a significant reduction in dangerous heart abnormalities.
  • Follow-up results indicated successful outcomes with normalized ECG and no further occurrences of ventricular arrhythmias, highlighting the effectiveness of this automated mapping and ablation strategy.

Article Synopsis
  • Degraded semantic memory is a key feature of frontotemporal dementia (FTD), affecting both social and general knowledge, particularly in cases of semantic dementia and anterior temporal lobe (ATL) atrophy.
  • Recent research has focused on how social-semantic knowledge is impacted in FTD, with a specific interest in the role of the right ATL compared to the left ATL.
  • A study involving various FTD types and control groups found that social and non-social semantic deficits were significantly correlated in FTD, while unilateral ATL resection led to milder impairments without clear left/right differences in knowledge.

Simple imaging biomarker predicts survival in anal squamous cell cancer treated with curative intent: a UK cohort study.

Clin Radiol

October 2024

Imperial College London (Department of Surgery and Cancer), Department of Surgery and Cancer, Imperial College, Room BN1/2, B Block 1st Floor, Hammersmith Campus, Imperial College, Du Cane Road, W12 0HS, UK. Electronic address:

Aim: This study aimed to determine the prognostic significance of length of tumour (mrT stage) and depth of extramural spread (mrEMS) in anal squamous cell cancer (SCC) treated by chemoradiation with curative intent. Locally advanced anal SCC (T3-4 N+) have poorer prognosis, but it is unknown whether the lateral spread of the tumour (extramural spread beyond the bowel wall) also confers poor prognosis in anal SCC, as it does for rectal cancer. T stage and mrEMS can be readily assessed by pelvic magnetic resonance imaging (MRI) routinely undertaken to stage anal SCC.

Decoding Apelin: Its Role in Metabolic Programming, Fetal Growth, and Gestational Complications.

Children (Basel)

October 2024

Third Department of Obstetrics and Gynecology, University General Hospital "ATTIKON", Medical School, National and Kapodistrian University of Athens, 124 62 Athens, Greece.

Placental insufficiency and gestational diabetes, which are both serious pregnancy complications, are linked to altered fetal growth, whether restricted or excessive, and result in metabolic dysfunction, hypoxic/oxidative injury, and adverse perinatal outcomes. Although much research has been carried out in this field, the underlying pathogenetic mechanisms have not as yet been fully elucidated. Particularly because of the role it plays in cardiovascular performance, glucose metabolism, inflammation, and oxidative stress, the adipokine apelin was recently shown to be a potential regulator of fetal growth and metabolic programming.
