PARP-2 sustains erythropoiesis in mice by limiting replicative stress in erythroid progenitors

, 2015
Erythropoiesis is a tightly regulated process in which multipotential hematopoietic stem cells produce mature red blood cells. Here we show that deletion of poly(ADP-ribose) polymerase-2 (PARP-2) in mice leads to chronic anemia at steady state, despite ...

Perioperative Transfusion Trigger Score Versus Restrictive Transfusion in Older Non‐Cardiac Surgery Patients: A Multicenter Randomized Controlled Trial

Journal of the American Geriatrics Society, EarlyView.
ABSTRACT Background Restrictive transfusion (Hb < 7 g/dL) is recommended for most perioperative patients, but the optimal threshold for those with cardiovascular disease or Hb 7–10 g/dL remains uncertain. The Perioperative Transfusion Trigger Score (POTTS), which integrates adrenaline requirement, FiO2, temperature, and angina history, may standardize ...

Congenital Skin Sloughing in the Setting of Hydrops Fetalis Secondary to Congenital Diffuse Lymphangiectasia Mimicking Epidermolysis Bullosa

Pediatric Dermatology, EarlyView.
ABSTRACT We present a case where the combination of severe hydrops fetalis, lymphangiectasia, and skin desquamation created a clinical picture that masqueraded as epidermolysis bullosa (EB). A neonate presented at birth with severe hydrops fetalis and extensive skin sloughing.

A low‐cost handheld device for monitoring cutaneous photosensitivity

Photochemistry and Photobiology, EarlyView.
The cutaneous photosensitivity detection (CPD) device is a handheld contact‐based measurement device using 405 nm excitation and red fluorescence detection for monitoring skin phototoxicity risk after photodynamic therapy (PDT) procedures involving systemic aminolaevulinic acid (ALA) induced protoporphyrin IX (PpIX) photosensitization.

Histiocytes: Multifaceted Regulators of Health and Disease

Veterinary Clinical Pathology, EarlyView.
ABSTRACT The mononuclear phagocyte system encompasses macrophages, dendritic cells (DCs), and monocytes. Tissue‐resident macrophages and dendritic cells arise during embryogenesis and are replenished either through self‐renewal or by monocytes during inflammation.

Codocytosis in the Dog: 345 Cases (2020–2022)

Veterinary Clinical Pathology, EarlyView.
ABSTRACT Introduction Codocytes, or target cells, are a morphologic variation of erythrocytes characterized by increased membrane surface area relative to volume. In dogs, codocytosis is frequently noted on blood smear evaluation, but its clinical significance remains poorly understood. Objectives To characterize the clinical conditions associated with

Case Report: T‐Lymphoblastic Leukemia in a Dog With Erythrophagia

Veterinary Clinical Pathology, EarlyView.
ABSTRACT A 2‐year‐old male German Shepherd dog was presented with progressive weight loss, lethargy, and hyporexia. Hematologic analysis revealed a moderate macrocytic normochromic anemia and moderate thrombocytopenia. Additionally, a pronounced leukocytosis was observed, characterized by 33% large lymphoid cells, marked neutrophilia with a significant

Molecular pathophysiology of chronic kidney disease–mineral and bone disorder: Focus on the fibroblast growth factor 23–Klotho axis and bone turnover dynamics

Experimental Physiology, EarlyView.
Abstract Chronic kidney disease–mineral and bone disorder (CKD‐MBD) is a major complication of chronic kidney disease (CKD), characterized by disruptions in mineral metabolism, abnormal bone turnover and vascular calcification, which collectively increase the risk of fractures and cardiovascular disease.

Contemporary Management of Thalassemia: A Perspective on Current Standards and the Emergence of FDA-Approved Oral Therapy. [PDF]

Health Sci Rep
ABSTRACT Background and Aims Thalassemia is an inherited hemoglobin disorder characterized by ineffective erythropoiesis, chronic anemia, and progressive multisystem complications that require lifelong management. Current treatment relies on regular red blood cell transfusions, iron chelation therapy, and supportive multidisciplinary care, while ...

Daily hot‐water immersion preserves altitude‐induced haemoglobin mass expansion following descent independent of erythropoietin

Experimental Physiology, EarlyView.
Abstract High‐altitude exposure increases haemoglobin mass (Hbmass), a key determinant of arterial oxygen‐carrying capacity, but following descent this adaptation can regress toward baseline within 7 days. Long‐term heat acclimation has emerged as an alternative stimulus for Hbmass expansion; however, whether post‐altitude passive‐heat exposure can ...
