Prolymphocytic leukaemia is a rare subtype of chronic lymphocytic leukaemia. Three such cases are reported here along with clinical details. All these cases were seen in males above 5th decade of life. These patients showed moderate to massive splenomegaly, inconspicuous lymphadenopathy in two cases and one with minimal lymphadenopathy. Peripheral smear showed high leucocyte count with more than 55% of prolymphocytes. Bone marrow aspiration showed diffuse involvement; and in one with minimal lymphadenopathy, lymph node aspiration showed prolymphocytes. All the three patients died within a year after diagnosis.

College of Animal Science and Technology, Shandong Agricultural University, Tai'an, Shandong, People's Republic of China.
In the last decade, the emergence of variant strains of avian orthoreovirus (ARV) has caused an enormous economic impact on the poultry industry across China and other countries. This study aimed to evaluate the molecular evolution of the ARV lineages detected in Chinese commercial broiler farms. Firstly, ARV isolation and identification of commercial broiler arthritis cases from different provinces in China from 2016 to 2021 were conducted.

Background: This research explores complement activation products involvement and risk and protective polymorphisms in the complement alternative pathway genes in Shiga toxin-associated hemolytic uremic syndrome (STEC-HUS) pathogenesis.
Methods: We analyzed the levels of complement activation products, C3a, C5a and soluble C5b-9 (sC5b-9) and plasma concentrations of Factor H (FH) and FH-related protein 1 (FHR-1) in 44 patients with STEC-HUS, 12 children with STEC-positive diarrhea (STEC-D), and 72 healthy controls (HC). STEC-HUS cases were classified as "severe" or "non-severe".
Clinical practice guidelines for management of disseminated intravascular coagulation in Japan 2024. Part 3: solid cancers and vascular abnormalities.
Int J Hematol

Associated Department With Mie Graduate School of Medicine, Mie Prefectural General Medical Center, Yokkaichi, Japan.
This study discusses disseminated intravascular coagulation (DIC) associated with solid cancers and various vascular abnormalities, both of which generally exhibit chronic DIC patterns. Solid cancers are among the most significant underlying diseases that induce DIC. However, the severity, bleeding tendency, and progression of DIC vary considerably depending on the type and stage of the cancer, making generalization difficult.

Background: While invasive fusariosis and lomentosporiosis are known to be associated with fungemia, overall data on mold-related fungemia are limited, hampering early management. This study aimed to describe the epidemiology of mold-positive blood cultures.
Methods: Epidemiological and clinical data on mold-positive blood cultures from 2012 to 2022 were obtained from the RESSIF database.
Chromosomal Abnormalities in Miscarriages and Maternal Age: New Insights from the Study of 7118 Cases.

Chromosomal abnormalities of the embryo are the most common cause of first-trimester pregnancy loss. In this single-center study, we assessed the frequency and the spectrum of chromosomal abnormalities in miscarriages for each year of maternal age from 23 to 44. Cytogenetic data were obtained by conventional karyotyping of 7118 miscarriages in women with naturally conceived pregnancies.
