Faecal specimens were collected from patients complaining of diarrhoea and abdominal or epigastric discomfort at two hospitals. Information obtained by questionnaires completed at the time of specimens collection, included demographic and clinical data. Specimens were preserved in 10% formalin and polyvinyl alcohol (PVA) and examined, as wet mounts and stained with Wheatley's Trichrome, Weber, modified acid-fast and hot safranin stains. One hundred patients were examined, in 30 of them parasites were detected. The most common organism identified was Cryptosporidium parvum, in specimens of five patients, followed by Entamoeba histolytica/E. dispar in four patients. The recently described "emerging parasites" were detected. Helminth eggs were found in two patients only. HIV status was not known for most of the patients, and the parasites commonly proliferate in the immuno-compromised individuals were not frequently found.

Department of Orthopedic Surgery, St. Vincent's Hospital, College of Medicine, the Catholic University of Korea, Seoul, Republic of Korea.
Objective: Central sensitization (CS) is associated with quality of life (QOL) after total knee arthroplasty (TKA). However, how CS changes after TKA and whether these changes have clinical relevance remain unclear. Therefore, this study was conducted to identify changes in CS after TKA and to assess the clinical significance of these changes.

Triple-negative breast cancer (TNBC) remains a significant global health challenge, emphasizing the need for precise identification of patients with specific therapeutic targets and those at high risk of metastasis. This study aimed to identify novel therapeutic targets for personalized treatment of TNBC patients by elucidating their roles in cell cycle regulation. Using weighted gene co-expression network analysis (WGCNA), we identified 83 hub genes by integrating gene expression profiles with clinical pathological grades.

Departement de Pathologie, Centre Hospitalo-Universitaire Montpellier, Montpellier, France.
Background: The detection rate of oncogenic human papillomaviruses (HPVs) in sinonasal squamous cell carcinomas (SNSCCs) varies among studies. The mutational landscape of SNSCCs remains poorly investigated.
Methods: We investigated the prevalence and prognostic significance of HPV infections based on p16 protein expression, HPV-DNA detection, and E6/E7 mRNA expression using immunohistochemistry, polymerase chain reaction, and in situ hybridization, respectively.
