Low-grade endometrial stromal sarcoma (LG-ESS) can present diagnostic challenges, due to its overlapping morphological features with other uterine mesenchymal tumors. Misdiagnosis rates remain significant, and immunohistochemical data for LG-ESS are limited to small series and inconsistent antibody panels. This study aimed to refine the IHC profile of LG-ESS by analyzing a large, molecularly confirmed series of 147 cases using a panel of 24 antibodies, including newer markers like transgelin and smoothelin.

As musculoskeletal injuries in gastroenterologists related to the performance of endoscopic procedures are on the rise, solutions and new approaches are needed to prevent these undesired outcomes. In our study, we evaluated an approach to ergonomic challenges in the form of a belt-like endoscope holder designed to redistribute the weight of the endoscope across the whole body of the practitioner. The aim of the study was to determine how the use of this holder affected the body posture of practitioners during endoscopy.

Patient-derived organoids (PDOs) and xenografts (PDXs) are powerful tools for personalized medicine in pancreatic cancer (PC) research. This study explores the complementary strengths of PDOs and PDXs in terms of practicality, genetic fidelity, cost, and labor considerations. Among other models like 2D cell cultures, spheroids, cancer-on-chip systems, cell line-derived xenografts (CDX), and genetically engineered mouse models (GEMMs), PDOs and PDXs uniquely balance genetic fidelity and personalized medicine potential, offering distinct advantages over the simplicity of 2D cultures and the advanced, but often resource-intensive, GEMMs and cancer-on-chip systems.

Article Synopsis
  • - Uterine sarcomas with KAT6B/A::KANSL1 fusion are a new type of tumor that show a mix of traits from low-grade endometrial stromal sarcomas and smooth muscle tumors, which can confuse initial diagnoses.
  • - A study involving 9 such cases found common features like expression of smooth muscle and endometrial stromal markers, as well as the presence of the KAT6B/A::KANSL1 fusion in all tumors.
  • - Despite their bland appearance, these tumors can be aggressive, with some patients experiencing severe outcomes, underscoring the need for accurate recognition and diagnosis for better treatment approaches.

  • This study analyzes 37 ovarian Sertoli-Leydig cell tumors (SLCT) with a focus on their morphology, immunohistochemistry, and molecular features, categorizing them into well, moderately, and poorly differentiated tumors.
  • High levels of sex cord markers were found, along with variable expression of other markers, and notable mutations like DICER1 (54.5%) and FOXL2 (6%) were identified, suggesting important diagnostic and predictive implications.
  • Differences in mRNA expression profiles between DICER1 and non-DICER1 tumors highlight the distinct molecular characteristics of SLCTs, indicating that well-differentiated tumors could represent a unique subtype apart from the others.

Department of Obstetrics and Gynecology, University Hospital Kralovske Vinohrady, 3rd Medical Faculty, Charles University in Prague, Czech Republic.

The incidence of cancer during pregnancy is steadily rising because of the postponement of plans for childbearing. One of the most common cancers diagnosed during pregnancy is cervical cancer. Diagnosis of most cases usually occurs in the early stages, but there are still cases of tumors staged IB2 and higher.

Department of Otorhinolaryngology 3rd Faculty of Medicine and University Hospital Kralovske Vinohrady, Charles University Prague Czech Republic.

Pulmonary atresia with ventricular septal defect and major aortopulmonary collateral arteries, paragangliomas, and syringomyelia are uncommon diseases. Furthermore, in the absence of any genetic link and with less than five reported adult patients surviving unrepaired rare form of Tetralogy of Fallot, our case shows noteworthiness. The possibility of definitive treatment of these conditions is rendered unsafe due to this persistent defect.

Purpose: During the initial phase of the pandemic, healthcare professionals faced difficulties due to the limited availability of comprehensive learning resources on managing patients affected with coronavirus disease 2019 (COVID-19). The COVID-19 Skills Preparation Course (C19_SPACE) was tailored to meet the overwhelming demand for specialized training. The primary objective of this study was to assess the efficacy and impact of this program on enhancing clinical knowledge and to identify factors affecting this improvement.

Department of Pathology, 3rd Faculty of Medicine, Charles University, University Hospital Kralovske Vinohrady, Šrobárova 1150/50, Praha 10, 10034, Prague, Czech Republic.

Colorectal cancer (CRC) is a leading global cause of illness and death. There is a need for identification of better prognostic markers beyond traditional clinical variables like grade and stage. Previous research revealed that abnormal expression of cytokeratin 7 (CK7) and loss of the intestinal-specific Special AT-rich sequence-binding protein 2 (SATB2) are linked to poor CRC prognosis.

  • Excessive heart rates in septic shock patients can negatively impact their health, prompting a study on the use of the ultra-short-acting beta-blocker landiolol to control heart rate without raising the need for vasopressors.
  • Conducted across 20 sites in Europe from 2018 to 2022, the study compared landiolol combined with standard treatment to standard treatment alone in adults with septic shock and high heart rates, focusing on maintaining a target heart rate (80-94 bpm) without increasing vasopressor requirements.
  • Results showed that a higher percentage of patients receiving landiolol achieved the target heart rate compared to those receiving standard treatment (39.8% vs. 23.5%), but there were no

Background: Pembrolizumab plus chemotherapy provides clinically meaningful benefit as first-line therapy for advanced (locoregional extension and residual disease after surgery)/metastatic/recurrent mismatch repair-proficient (pMMR) and mismatch repair-deficient (dMMR) endometrial cancer, with greater magnitude of benefit in the dMMR phenotype. We evaluated the addition of pembrolizumab to adjuvant chemotherapy (with/without radiation therapy) among patients with newly diagnosed, high-risk endometrial cancer without any residual macroscopic disease following curative-intent surgery.

Methods: We included patients with histologically confirmed high-risk [International Federation of Gynecology and Obstetrics (FIGO) stage I/II of non-endometrioid histology or endometrioid histology with p53/TP53 abnormality, or stage III/IVA of any histology] endometrial cancer following surgery with curative intent and no evidence of disease postoperatively, with no prior radiotherapy or systemic therapy.

Purpose: To determine the optimal daunorubicin dose and number of 7 + 3 induction cycles in newly diagnosed AML, this randomized controlled trial compared a once daily dose of 60 mg/m with 90 mg/m daunorubicin in the first 7 + 3 induction and one versus two cycles of 7 + 3 induction.

Patients And Methods: Patients age 18-65 years with newly diagnosed AML were randomly assigned to 60 versus 90 mg/m daunorubicin once daily plus cytarabine. Patients with marrow blasts below 5% on day 15 after first induction were randomly assigned to receive a second induction cycle or no second induction cycle.

Background: Stathmin, a cytosolic microtubule-destabilizing phosphoprotein involved in the regulation of mitosis, is widely expressed in various malignancies and acts as an adverse prognostic factor. Our research analyzed its immunohistochemical expression on a large cohort of ovarian sex cord-stromal tumors, evaluating its potential utility in differential diagnosis, prognosis, and therapeutic application.

Methods: We examined 390 cases of ovarian sex cord-stromal tumors including 281 adult granulosa cell tumors (AGCT), 5 juvenile granulosa cell tumors (JGCT), 33 Sertoli-Leydig cell tumors (SLCT), 50 fibromas/thecomas (F/T), 11 Leydig cell tumors/steroid cell tumors (LCT/SterCT), 5 sex-cord stromal tumors NOS (SCST-NOS), 3 Sertoli cell tumors (SCT), and 2 sclerosing stromal tumors (ScST).

  • - Our study looked at fungal infections in patients with acute myeloid leukemia being treated with venetoclax and azacitidine, comparing those who received antifungal prophylaxis (AFP) to those who didn't.
  • - Out of 186 patients, only 1 out of 85 (1%) with AFP developed a fungal infection, while 5 out of 101 (5%) without AFP got infected, showing no significant difference between the two groups.
  • - Overall, the study found that fungal infections were mostly mild and appeared early in treatment, and they did not significantly impact patient survival or death rates.
