Objective: The primary aim of this study was to determine whether pulmonary artery acceleration time (AT) to ejection time (ET) ratio (PATET) was altered in fetuses of mothers with intrahepatic cholestasis of pregnancy (IHCP). The secondary aim was to investigate the association between fetal pulmonary artery Doppler parameters with neonatal outcomes in pregnancies complicated by IHCP.
Material And Methods: This prospective case control study was conducted in a tertiary perinatal-neonatal center. A total of 18 fetuses whose mothers’ pregnancies were complicated by IHCP were included as the study group and a total of 37 fetuses of mothers with healthy pregnancies were selected as controls. Fetal pulmonary artery Doppler parameters (AT; ET; AT/ET ratio) were assessed and neonatal outcomes were evaluated.
Results: Mean pulmonary artery AT, ET and PATET were significantly different between the groups (p=0.001, p=0.024 and p=0.003, respectively). The mean PATET value in the IHCP group was 0.217±0.029 while in the control group it was 0.180±0.020. While PATET values were correlated with gestational age at birth, respiratory distress and need for neonatal intensive care admission were not correlated with PATET.
Conclusion: Higher values of PATET may be a useful biomarker of fetal lung damage, secondary to IHCP.

The aims of this study were to investigate the prevalence of cryofibrinogenemia in a cohort of patients with systemic sclerosis (SSc) regardless of clinical manifestations, who were admitted to our hospital and determine the associations among CF positivity, disease features and ongoing therapies. This was a monocentric and retrospective study. The inclusion criteria were a diagnosis of SSc (according to the ACR/EULAR 2013 classification criteria), regular administration of i.

Background: Real-time (RT) phase contrast (PC) flow MRI can potentially be used to measure blood flow in arrhythmic patients. Undersampled RT PC has been combined with online compressed sensing (CS) reconstruction (CS RT) enabling clinical use. However, CS RT flow has not been validated in a clinical setting.

Aims: There are few data on the prognostic impact of pulmonary-right ventricular (RV) uncoupling in patients with wild-type transthyretin amyloid cardiomyopathy (ATTRwt-CM).
Methods And Results: Among the 174 patients who were diagnosed with ATTRwt-CM at Kumamoto University Hospital from 2002 to 2021, 143 patients who met the current Japanese guideline and had sufficient information for two-dimensional speckle tracking echocardiography were retrospectively analysed. During a median follow-up of 1209 days, 39 cardiac deaths occurred.

Unlabelled: Heparin-induced thrombocytopenia (HIT) is an immune-mediated disease with severe thromboembolic complications. HIT during percutaneous coronary intervention (PCI) can be fatal without prompt treatment. We report an unusual case of HIT observed during PCI for acute coronary syndrome (ACS).
