Regulation of neuroimmune interactions varies across avian species. Little is presently known about the interplay between periphery and central nervous system (CNS) in parrots, birds sensitive to neuroinflammation. Here we investigated the systemic and CNS responses to dextran sulphate sodium (DSS)- and lipopolysaccharide (LPS)-induced subclinical acute peripheral inflammation in budgerigar (Melopsittacus undulatus).

Rhabdomyosarcoma (RMS) of the urinary bladder in adults and elderly is an exceptionally rare neoplasm that displays poorly differentiated solid (alveolar-like) small cell pattern, frequently indistinguishable from small cell neuroendocrine carcinoma (SCNEC). However, the histogenesis of RMS and SCNEC and their inter-relationship have not been well studied and remained controversial. We herein analyzed 23 SCNEC and 3 small round cell RMS of the bladder for neuroendocrine (synaptophysin + chromogranin A) and myogenic (desmin + myogenin) marker expression and for TERT promoter mutations.

Background: Prostate cancer develops through malignant transformation of the prostate epithelium in a stepwise, mutation-driven process. Although activator protein-1 transcription factors such as JUN have been implicated as potential oncogenic drivers, the molecular programs contributing to prostate cancer progression are not fully understood.

Methods: We analyzed JUN expression in clinical prostate cancer samples across different stages and investigated its functional role in a Pten-deficient mouse model.

Multiparametric analysis of the specific immune response against SARS-CoV-2.

Infect Dis (Lond)

October 2024

Department of Genetics and Microbiology, Faculty of Science, Charles University, BIOCEV, Vestec, Czech Republic.

Background: SARS-CoV-2, which causes COVID-19, has killed more than 7 million people worldwide. Understanding the development of postinfectious and postvaccination immune responses is necessary for effective treatment and the introduction of appropriate antipandemic measures.

Objectives: We analysed humoral and cell-mediated anti-SARS-CoV-2 immune responses to spike (S), nucleocapsid (N), membrane (M), and open reading frame (O) proteins in individuals collected up to 1.

Article Synopsis
  • A phase 3 trial found that neoadjuvant treatment with nivolumab plus chemotherapy improved event-free survival in patients with resectable non-small-cell lung cancer (NSCLC) compared to chemotherapy alone, with 70.2% of the nivolumab group remaining event-free at 18 months, versus 50.0% in the chemotherapy group.!* -
  • Patients receiving nivolumab also had a significantly higher rate of pathological complete response (25.3%) compared to those on chemotherapy (4.7%), indicating better treatment efficacy.!* -
  • The safety profile was similar between both groups, with 32.5% of nivolumab patients experiencing grade 3 or 4 treatment-related adverse events

Hairy cell leukemia (HCL) and HCL-like disorders have to be distinguished because of their different biology and treatment response. Thus, we conducted a retrospective study on patients with HCL and hairy cell leukemia variant (HCLv) to assess diagnostic algorithms and treatment outcomes in a real-world setting. We analyzed 225 HCL and 26 HCLv patients with median follow-up of 67.

Article Synopsis
  • Venetoclax (VEN) shows promising activity against various lymphomas and leukemias, but remissions tend to be short, prompting the need for combination therapies.
  • Research found that combining VEN with A1155463, a BCL-XL inhibitor, created a strong synergistic effect and could overcome resistance in certain cell lines, even those lacking BCL2L11/BIM, which is often linked to VEN resistance.
  • In vivo studies confirmed the effectiveness of this combination in multiple patient-derived models, and a unique treatment schedule of 4 days on/3 days off minimized side effects, making this a potential innovative approach for treating BCL2+ hematologic malignancies.

Cancer is still one of the leading causes of death, with an estimated 19.3 million new cases every year. Our paper presents the tumor-suppressing effect of and on B16F10 melanoma, the intraperitoneal application of which followed the experimental infection with these tapeworms, resulting in varying degrees of effectiveness in two strains of mice.

Article Synopsis
  • * Proper selection of SG candidates and tailored post-surgery care are crucial to maintain the benefits of surgery while minimizing side effects like muscle loss, particularly since CKD patients have distinct nutritional and metabolic needs compared to the general bariatric population.
  • * The paper emphasizes the importance of comprehensive psychosocial support and ongoing management of health conditions related to CKD during the waiting period for kidney transplantation and calls for future studies to explore effective treatments for this unique patient group.

Article Synopsis
  • Adenovirus (AdV) infection in the respiratory tract is common but not well understood, especially how HAdV-C5, a type of human AdV, enters cells.* -
  • A new model suggests that human lactoferrin (hLF) helps the virus bypass traditional receptors by facilitating its uptake into epithelial cells through interactions with the viral protein hexon.* -
  • The study provides detailed cryo-EM structures showing how hLF connects with hexon, which could enhance understanding for gene therapy and vaccine development.*

Article Synopsis
  • The study evaluated what factors affect how long biologic drugs work for children with Crohn's disease, using data from the Czech National Registry.
  • Findings showed that infliximab had a higher discontinuation risk compared to adalimumab, and that starting treatment sooner after diagnosis improved sustainability.
  • The study concluded that the effectiveness of these treatments isn't equal, as infliximab requires more frequent adjustments and immunosuppression than adalimumab.

Background: In the GLOW study, fixed-duration ibrutinib-venetoclax showed superior progression-free survival versus chlorambucil-obinutuzumab in patients with previously untreated chronic lymphocytic leukaemia who were older or had comorbidities, or both, at a median follow up of 27·7 months. In this Article, we report updated outcomes from GLOW after a 46-month median follow-up.

Methods: GLOW was a randomised, multicentre, phase 3 study done at 67 hospital centres across 14 countries.

Mesenchymal neoplasms with GLI1 alterations have recently been reported in several anatomic locations. Their morphology and immunohistochemistry (IHC) are nonspecific, making their recognition a true challenge. To assess the diagnostic value of GLI1 and p16 IHC for identifying GLI1-altered neoplasms, we evaluated 12 such neoplasms (6 GLI1-amplified and 6 with GLI1-fusions) using the GLI1 IHC.

Matricidal carotid cavernous aneurysm (CCA) is a rare and dangerous condition. The treatment failure of the endovascular approach like flow diversion, coiling, or stent-coiling is relatively high with considerable morbidity and mortality. The transcirculation approach is an alternative treatment option, but in case of matricidal CCAs, the results are not well documented in the literature.

Novel Method for Detecting the Stage of Arthrosis and Femoroacetabular Impingement Using a Gyroscopic Sensor and Neural Networks.

Acta Chir Orthop Traumatol Cech

October 2023

University of Defence, Faculty of Military Health Sciences, Department of Military Surgery, Hradec Králové, Czech Republic.

PURPOSE OF THE STUDY Femoroacetabular impingement syndrome is a complex, often post-traumatically developing impairment of the hip joint, characterized by ambiguous symptomatology, which makes early diagnosis diffi cult, especially in the early stages. Experimental retrospective study was carried out to evaluate the usability of a triaxial gyroscopic sensor in routine practice as an additional indication criterion for operative versus conservative treatment procedures. MATERIAL AND METHODS 92 patients were included in the retrospective study, and 62 completed the investigation.

In this retrospective international multicenter study, we describe the clinical characteristics and outcomes of patients with chronic lymphocytic leukemia (CLL) and related disorders (small lymphocytic lymphoma and high-count monoclonal B lymphocytosis) infected by SARS-CoV-2, including the development of post-COVID condition. Data from 1540 patients with CLL infected by SARS-CoV-2 from January 2020 to May 2022 were included in the analysis and assigned to four phases based on cases disposition and SARS-CoV-2 variants emergence. Post-COVID condition was defined according to the WHO criteria.
