The effective prognostic factors for primary mediastinal large B-cell lymphoma (PMLBCL) vary among published studies. The aim of the present study was to explore the factors influencing the overall survival (OS) and progression-free survival (PFS) of patients with PMLBCL at a single institute in Taiwan. This retrospective study was conducted to analyze the prognostic impact of age, sex, disease stage, International Prognostic Index (IPI) score, treatment modality and initial response. A total of 72 patients with a median age of 28 years were included in the study. The mean OS and PFS were 171.40 and 159.77 months, respectively. Female sex, age ≤60 years, receiving radiotherapy (RT) and achieving a complete response were found to be associated with a significantly improved OS and PFS. In addition, high-intensity chemotherapy and an IPI score ≤1 were associated with longer OS, and early-stage disease was associated with a PFS superior to that of advanced-stage disease. The predictive value of IPI is limited in PMLBCL. Therefore, it is necessary to develop a novel prognostic system. The present study revealed the impact of sex on prognosis and, therefore, this factor should be considered in future prognostic evaluations. Since a complete post-treatment response was found to be important, high-intensity chemotherapy is recommended. However, low-intensity treatment followed by RT consolidation appears to be a feasible approach in elderly patients.

Posaconazole for Prevention of COVID-19-Associated Pulmonary Aspergillosis in Mechanically Ventilated Patients: A European Multicentre Case-Control Study (POSACOVID).
Mycoses

Division of Infectious Diseases, Department of Internal Medicine, Excellence Center for Medical Mycology (ECMM), Medical University of Graz, Graz, Austria.
Background: This study investigated the impact of posaconazole (POSA) prophylaxis in COVID-19 patients with acute respiratory failure receiving systemic corticosteroids on the risk for the development of COVID-19-associated pulmonary aspergillosis (CAPA).
Methods: The primary aim of this prospective, multicentre, case-control study was to assess whether application of POSA prophylaxis in mechanically ventilated COVID-19 patients reduces the risk for CAPA development. All consecutive patients from centre 1 (cases) who received POSA prophylaxis as standard-of-care were matched to one subject from centre 2 and centre 3 who did not receive any antifungal prophylaxis, using propensity score matching for the following variables: (i) age, (ii) sex, (iii) treatment with tocilizumab and (iv) time at risk.
Purpose: This study aimed to elucidate the correlation between the degree of fat infiltration (FI) in thoracic paraspinal muscles and thoracic vertebral degeneration (TVD).
Methods: This cross-sectional study comprised 474 patients who underwent standard thoracic computed tomography (CT) scans. The FI was quantified as the percentage of adipose tissues within the cross-sectional area of thoracic paraspinal muscles.

Background: Preceding studies of environmental and occupational risk factors of sarcoidosis yielded inconsistent findings.
Aims: We aimed to ascertain the occupational risk factors for sarcoidosis in a case-control study.
Methods: A total of 237 sarcoidosis patients with a histologically confirmed diagnosis were matched with 474 controls for sex and age (median 49, interquartile range 37; 60 years) recruited from the university hospitals and outpatient centres in Belarus, Kazakhstan and the Russian Federation.
Age-dependent differences in the association between blood interleukin-6 levels and mortality in patients with sepsis: a retrospective observational study.
J Intensive Care
January 2025
Department of Emergency and Critical Care Medicine, Chiba University Graduate School of Medicine, 1-8-1 Inohana, Chiba, 260-8677, Japan.
Background: Interleukin-6 (IL-6) is a cytokine that predicts clinical outcomes in critically ill patients, including those with sepsis. Elderly patients have blunted and easily dysregulated host responses to infection, which may influence IL-6 kinetics and alter the association between IL-6 levels and clinical outcomes.
Methods: This retrospective observational study included patients aged ≥ 16 years who were admitted to the intensive care unit at Chiba University Hospital.
