Neurocognitive impairment is a key concern in sickle cell disease (SCD) patients, affecting several factors including academic performance, employment and quality of life. While the exact causes remain unclear, correlations with silent cerebral infarcts (SCIs) and abnormal perfusion and oxygenation have been reported in paediatric SCD populations. This study aimed to examine these associations in adults with SCD, including 70 severe SCD patients (HbSS & HbSβ-thal), 22 mild SCD patients (HbSC & HbSβ-thal), 16 thalassaemia patients and 29 healthy controls.

Background: Familial hypercholesterolemia (FH) causes elevated low-density lipoprotein cholesterol (LDL-C) levels, leading to an increased risk for premature atherosclerotic cardiovascular disease (ASCVD). To prevent ASCVD, lipid-lowering therapy (LLT), such as statins, is needed from childhood on, to lower LDL-C levels. Arterial stiffness can serve as a surrogate marker for atherosclerosis.

: Elevated lipoprotein(a) [Lp(a)] and familial hypercholesterolemia (FH) are both inherited dyslipidemias that are independently associated with cardiovascular disease. Surrogate markers to assess signs of atherosclerosis, such as arterial stiffness, might be useful to evaluate the cardiovascular risk in young patients. The aim of this study is to evaluate the contribution of Lp(a) to arterial stiffness, as measured by carotid pulse wave velocity (cPWV) in young adults with FH.

Article Synopsis
  • Silent cerebral infarcts (SCIs) are common in patients with severe forms of sickle cell disease (SCD) and thalassemia, although the underlying causes are not fully understood.
  • This study compared cerebral blood flow, oxygen metabolism, and SCI lesions in severe and mild SCD patients, thalassemia patients, and healthy controls before and after a vasodilatory challenge.
  • Findings showed that while severe SCD and thalassemia patients had higher blood flow, their oxygen consumption was lower; this suggests that anemia rather than cerebral blood flow may play a key role in the development of SCIs, especially in milder forms of SCD.

The conventional gradient-echo steady-state signal model is the basis of various spoiled gradient-echo (SPGR) based quantitative MRI models, including variable flip angle (VFA) MRI and dynamic contrast-enhanced MRI (DCE). However, including preparation pulses, such as fat suppression or saturation bands, disrupts the steady-state and leads to a bias in T and DCE parameter estimates. This work introduces a signal model that improves the accuracy of VFA T-mapping and DCE for interrupted spoiled gradient-echo (I-SPGR) acquisitions.

Sickle cell disease (SCD) is complicated by silent cerebral infarcts (SCIs), for which anemia is an important risk factor. Despite normal oxygen delivery (OD), cerebral vascular reserve (CVR), and cerebral metabolic rate of oxygen (CMRO) are diminished in SCD, possibly causing the formation of SCIs. Voxelotor inhibits polymerization by increasing the hemoglobin oxygen binding, ameliorating hemolytic anemia.

Background: Left atrial volume index (LAVI) serves as a crucial marker for assessing left atrial (LA) remodeling, particularly in patients with mitral valve regurgitation (MR). Recent guidelines recommend a LAVI exceeding 60 mL/m as Class IIa recommendation for mitral valve repair surgery in asymptomatic MR patients with preserved left ventricular function. Traditionally, echocardiography is the standard for assessing LAVI in MR patients.

  • Intravoxel incoherent motion (IVIM)-corrected diffusion tensor imaging (DTI) can help predict return-to-play (RTP) readiness after hamstring injuries, but long scan times limit its usage.
  • The study tested accelerated methods of IVIM-corrected DTI by comparing standard scans and multiband (MB) accelerated scans within a week of injury and at RTP.
  • Results showed that MB acceleration significantly reduced scan duration while maintaining sensitivity to detect hamstring injuries, although the perfusion fraction (f) did not differ between injured and healthy muscles.

Animal studies suggest that short-chain fatty acids acetate and butyrate are key players in the gut-brain axis and may affect insulin sensitivity. We investigated the association of intestinal acetate and butyrate availability (measured by butyryl-coenzyme A transferase (ButCoA) gene amount) with insulin sensitivity and secretion in healthy subjects from the HELIUS cohort study from the highest 15% (N = 30) and the lowest 15% (N = 30) intestinal ButCoA gene amount. The groups did not differ in insulin sensitivity or secretion.
