High-energy nuclear collisions create a quark-gluon plasma, whose initial condition and subsequent expansion vary from event to event, impacting the distribution of the eventwise average transverse momentum [P([p_{T}])]. Disentangling the contributions from fluctuations in the nuclear overlap size (geometrical component) and other sources at a fixed size (intrinsic component) remains a challenge. This problem is addressed by measuring the mean, variance, and skewness of P([p_{T}]) in ^{208}Pb+^{208}Pb and ^{129}Xe+^{129}Xe collisions at sqrt[s_{NN}]=5.

This Special Issue examines the ways in which emerging or established social theorists from Continental Europe and the United States were personally and politically involved in and affected by the First the First World War (WWI), and considers how the war shaped their sociological theories. WWI was a pivotal moment that transformed global and historical systems in ways that challenged conventional social scientific assumptions about the supposed shift from "traditional" to "modern" societies and compelled sociologists to reconsider the impact of industry and military affairs on everyday life. The period from 1914 to 1918 has typically been ignored or bracketed by later scholars as a largely inconsequential gap in an otherwise uninterrupted flow of intellectual production.

Background: The diagnosis of Meniere's Disease (MD) presents significant challenges due to its complex symptomatology and the absence of definitive biomarkers. Advancements in MRI technology have spotlighted endolymphatic hydrops (EH) as a key pathological marker, necessitating a reevaluation of its diagnostic utility amidst the need for standardized and validated MRI-based grading scales.

Methods: Our meta-analysis scrutinized the diagnostic efficacy of semi-quantitative MRI-based cochlear endolymphatic hydrops (EH) and perilymphatic enhancement (PLE) grading systems in delineating clinically relevant discriminations: "Spotting" the shift from normal or asymptomatic ears to possible/probable MD (pMD), "Confirming" the progression to definite MD (dMD), and "Establishing" the presence of dMD.

Patients treated with RET protein tyrosine kinase inhibitors (TKIs) selpercatinib or pralsetinib develop RET TKI resistance by secondary RET mutations or alterative oncogenes, of which alterative oncogenes pose a greater challenge for disease management because of multiple potential mechanisms and the unclear tolerability of drug combinations. A patient with metastatic medullary thyroid carcinoma (MTC) harboring a RET activation loop D898_E901del mutation was treated with selpercatinib. Molecular alterations were monitored with tissue biopsies and cfDNA during the treatment.

Article Synopsis
  • Sarcoma spinal metastases (SSM) are tough to treat because they don’t respond well to chemotherapy and are resistant to radiation.
  • Researchers looked at 70 patients who received special radiation treatment called SSRS for these tumors over 16 years, finding that it helped control local tumors in most cases.
  • The study showed that the more radiation given to the tumor, the better the chances of preventing it from coming back, although some patients did experience side effects like fractures.
