Gliomas are highly dynamic and heterogeneous tumours of the central nervous system (CNS). They constitute the most common neoplasm of the CNS and the second most common cause of death from intracranial disease after stroke. The advances in detailing the genetic profile of paediatric and adult gliomas along with the progress in MRI and PET multimodal molecular imaging technologies have greatly improved prognostic stratification of patients with glioma and informed on treatment decisions. Amino acid PET has already gained broad clinical application in the study of gliomas. PET imaging targeting the translocator protein (TSPO) has recently been applied to decipher the heterogeneity and dynamics of the tumour microenvironment (TME) and its various cellular components especially in view of targeted immune therapies with the goal to delineate pro- and anti-glioma immune cell modulation. The current review provides a comprehensive overview on the historical developments of TSPO PET for gliomas and summarizes the most relevant experimental and clinical data with regard to the assessment and quantification of various cellular components with the TME of gliomas by in vivo TSPO PET imaging.

Due to demographic changes in today's society, the number of patients with lower urinary tract symptoms (LUTS) due to benign prostatic hyperplasia (BPH) is increasing. Similarly, the proportion of patients with cardiovascular risk factors undergoing antiplatelet (AP) or anticoagulation (AC) therapy is growing as well.

This review discusses the current literature on various techniques used for anatomic endoscopic enucleation of the prostate (AEEP) in patients on AC/AP therapy.

The large number of energy sources used for AEEP makes it difficult to compare them. Overall, fewer bleeding-associated complications arise in patients under AP compared to AC or bridging therapy with low molecular weight heparin. However, perioperatively both AP and AC therapy lead to a higher risk of bleeding complications compared to patients not taking anticoagulants.

The literature shows that AEEP is possible and efficacious in patients under AC/AP therapy, with only slight differences compared to patients not taking AC/AP drugs, on a short and long-term basis. Nevertheless, the sparse data, the retrospective nature of many studies and the inclusion of prostate sizes between 50 and 110ml only, make it difficult to come to strong conclusions.

Myocardial iron overload (MIO) in thalassemia major (TM) may cause subclinical left ventricular (LV) dysfunction which manifests with abnormal strain parameters before a decrease in ejection fraction (EF). Early detection of MIO using cardiovascular magnetic resonance (CMR)-T2* is vital. Our aim was to assess if CMR feature-tracking (FT) strain correlates with T2*, and whether it can identify early contractile dysfunction in patients with MIO but normal EF.

One hundred and four consecutive TM patients with LVEF > 55% on echocardiography were prospectively enrolled. Those fulfilling the inclusion criteria underwent CMR, with T2* being the gold standard for detecting MIO. Group 1 included patients without significant MIO (T2* > 20 ms) and group 2 with significant MIO (T2* < 20 ms).

Eighty-six patients (mean age, 17.32 years, 59 males) underwent CMR. There were 68 (79.1%) patients in group 1 and 18 (20.9%) in group 2. Fourteen patients (16.3%) had mild-moderate MIO, and four (4.6%) had severe MIO.urbances. • T1 and T2 mapping values are significantly lower in those with severe myocardial iron than those with mild-moderate iron, suggesting a potential role of T1 and T2 mapping in grading myocardial iron.

• A global radial strain of less then 29.3 derived from cardiac MRI could predict significant myocardial iron overload in patients with thalassemia, with a sensitivity of 76.5% and specificity of 66.7%. selleck kinase inhibitor • Patients with any myocardial iron overload have significantly lower GRS, compared to those without, suggesting the ability of CMR strain to identify subtle myocardial contractile disturbances. • T1 and T2 mapping values are significantly lower in those with severe myocardial iron than those with mild-moderate iron, suggesting a potential role of T1 and T2 mapping in grading myocardial iron.Mutations in proteins involved in cell division and chromosome segregation, such as microtubule-regulating, centrosomal and kinetochore proteins, are associated with microcephaly and/or short stature. In particular, the kinetochore plays an essential role in mitosis and cell division by mediating connections between chromosomal DNA and spindle microtubules. To date, only a few genes encoding proteins of the kinetochore complex have been identified as causes of syndromes that include microcephaly. We report a male patient with a rare de novo missense variant in NUF2, after trio whole-exome sequencing analysis. The patient presented with microcephaly and short stature, with additional features, such as bilateral vocal cord paralysis, micrognathia and atrial septal defect. NUF2 encodes a subunit of the NDC80 complex in the outer kinetochore, important for correct microtubule binding and spindle assembly checkpoint. The mutated residue is buried at the calponin homology (CH) domain at the N-terminus of NUF2, which interacts with the N-terminus of NDC80. The variant caused the loss of hydrophobic interactions in the core of the CH domain of NUF2, thereby impairing the stability of NDC80-NUF2. Analysis using a patient-derived lymphoblastoid cell line revealed markedly reduced protein levels of both NUF2 and NDC80, aneuploidy, increased micronuclei formation and spindle abnormality. Our findings suggest that NUF2 may be the first member of the NDC80 complex to be associated with a human disorder.
