Inorganic pyrophosphatase 1 (PPA1) is pivotal to cellular metabolism as it facilitates the hydrolysis of PPi-a by-product of various metabolic processes that influence cell growth and differentiation. Overexpression of PPA1 enzyme has been linked to diminished patient survival and was shown to influence tumor cell dynamics, thereby positioning it as a potential therapy target for a variety of cancers including colorectal cancer, diffuse large B-cell lymphoma, and lung adenocarcinoma. Despite this therapeutic promise, there are no known inhibitors of PPA1 as of today...

A 17-year-old captive female double yellow-headed Amazon parrot ( Amazona oratrix ) was presented to the Kansas State University Zoological Medicine Service (Manhattan, KS, USA) for a 2-month history of a left sided facial swelling. On examination, a red, raised mass was noted on the left side of the face. A whole-body computed tomography scan of the bird was performed to assess the extent of the mass and evaluate the patient for obvious evidence of disseminated disease. No systemic involvement was detected, and the swelling was localized to the cutaneous and subcutaneous tissues overlying the left rhamphotheca...

BACKGROUND: Arab countries are projecting increase in cancer incidence and mortality, however, there are limited studies that compare the epidemiology of cancer in Arab countries compared to other parts of the world. METHODS: We used the 2018 Global Cancer Observatory data to compare the age-standardized incidence and mortality estimates in Arab-speaking countries to the rest of the world. RESULTS: Rates for incidence and mortality for all cancers in Arab countries were lower than the world's rates but the incidence rates of non-Hodgkin and Hodgkin lymphoma, bladder, breast, and liver cancers were higher...

We retrospectively analyzed the outcomes of 136 consecutive patients who received allogeneic hematopoietic stem cell transplantation (allo-HSCT) at our center. Among them, 76 cases used hypomethylating agents (decitabine, n  = 40; azacitidine, n  = 36) as post-transplant maintenance therapy, whereas 60 contemporaneous patients did not adopt maintenance therapy. The 3-year incidences of relapse in two groups were 16.6% and 39.2% ( p  = .001). The 3-year OS and DFS in maintenance group were 84...

B-cell targeted therapies, including anti-CD20 monoclonal antibodies (mAb) and Bruton's tyrosine kinase inhibitors (BTKi), further suppress antibody (Ab) response to vaccines in patients with chronic lymphocytic leukemia (CLL). We conducted a prospective cohort study of SARS-CoV-2 vaccination in 81 CLL patients receiving BTKi ( n  = 54), venetoclax (VEN, n  = 9), or who were treatment naïve (TN, n  = 18). Anti-spike Ab were detected in 53% of patients on BTKi post-primary series and 84% post-booster, 57% of patients on VEN post-primary series and 50% post-booster, and 67% of TN patients post-primary series and 87% post-booster...

The treatment landscape for chronic lymphocytic leukemia (CLL) has been transformed by the availability of Bruton's tyrosine kinase inhibitors (BTKis) and the B-cell lymphoma 2 (BCL-2) inhibitor venetoclax. Despite clinical trial data supporting these novel oral agents, evidence evaluating real-world adherence is limited. This study used 2015-2019 Medicare claims data for elderly patients with relapsed/refractory CLL to assess differences in real-world adherence and discontinuation in the 12 months after treatment initiation...

Wear particle‑induced osteolysis is a serious complication that occurs in individuals with titanium (Ti)‑based implants following long‑term usage due to loosening of the implants. The control of excessive osteoclast differentiation and inflammation is essential for protecting against wear particle‑induced osteolysis. The present study evaluated the effect of britanin, a pseudoguaianolide sesquiterpene isolated from Inula japonica , on osteoclastogenesis in vitro and Ti particle‑induced osteolysis in vivo ...

BACKGROUND: Our aim was to assess associations between cardiorespiratory fitness (CRF) and body mass index (BMI) in youth and 5-year mortality after site-specific cancer diagnoses in men. METHODS: Men with cancer from a population who underwent military conscription at ages 16-25 during 1968-2005 in Sweden were included. CRF was assessed as maximal aerobic workload on a cycle ergometer test and was classified as low, moderate, or high. BMI (kg/m2 ) was classified as underweight (<18...

Intrathecal chemotherapy is used in human medicine for the treatment or prophylaxis of CNS hematopoietic neoplasia. However, the clinical benefits in veterinary medicine have been scarcely documented. A 4-year-old male entire cross-breed dog presented with a 24-h history of severe lethargy, pelvic limb weakness, and urinary retention. Examination revealed generalized peripheral lymphadenomegaly, and the neurological findings were suggestive of a myelopathy in the region of T3-L3. Following the diagnosis of multicentric lymphoblastic B-cell lymphoma (stage Vb), a modified L-LOP with cytosine arabinoside was started, and complete clinical remission was achieved...

Inflammatory bowel disease is a common condition in cats, characterized by recurring gastrointestinal signs with histologic evidence of intestinal inflammation. A 9-month-old neutered male Sphynx cat was presented with a 5-week history of vomiting and hematochezia. Conservative patient management with a therapeutic gastrointestinal formula, antibiotics, and antiemetics resulted in a positive response to treatment, with relapse of signs when the medications were discontinued. A new finding of marked eosinophilia and basophilia was identified 3 months after the initial presentation...

INTRODUCTION: Although breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) is infrequent, with less than 1000 noted cases worldwide, patients consenting for breast implant surgery should be aware of its risk. We describe the first Polish multicenter case-series data on BIA-ALCL patients and present diagnostic and treatment recommendation for breast surgeons. MATERIAL AND METHODS: In cooperation with the Polish Society of Surgical Oncology and Polish Lymphoma Research Group, we collected BIA-ALCL cases in Poland...

Hepatitis due to hepatitis B virus (HBV) reactivation can be serious and potentially fatal, but is preventable. HBV reactivation is most commonly reported in patients receiving chemotherapy, especially rituximab-containing therapy for hematological malignancies and those receiving stem cell transplantation. Patients with inactive and even resolved HBV infection still have persistence of HBV genomes in the liver. The expression of these silent genomes is controlled by the immune system. Suppression or ablation of immune cells, most importantly B cells, may lead to reactivation of seemingly resolved HBV infection...

Castleman disease is an infrequent disease that affects the lymph nodes and related tissues. The condition may manifest with lymphadenopathy, characterized by the enlargement of the lymph nodes, alongside additional symptoms such as high fever, nocturnal sweating, exhaustion, and loss of body mass. The diagnosis of Castleman disease typically entails a multifaceted approach that includes a physical examination, imaging modalities, and a biopsy of the lymph nodes that are affected. The selection of treatment modalities is contingent upon the classification and extent of the disease...

The interaction of the inducible co-stimulator (ICOS) with its ligand (ICOSL) plays key roles in T-cell differentiation and activation of T-cell to B-cell functions. The ICOS/ICOSL pathway is a validated target for T-cell lymphomas induced by the proliferation of T-follicular helper (Tfh) cells. Moreover, the inhibition of ICOS/ICOSL interaction can decrease the enhancement of immunosuppressive regulatory T cells (Tregs) in both hematologic malignancies and solid tumors. However, targeting ICOS/ICOSL interaction is currently restricted to monoclonal antibodies (mAbs) and there are no small molecules in existence that can block ICOS/ICOSL...

T-large granular lymphocytes (T-LGL) characterized by dim CD5 staining, although not completely understood, have unique roles in the immune system. Expansion of peripheral blood (PB) clonal T-LGL populations is associated with various entities in adults. We have previously demonstrated clonal T-LGL proliferations in pediatric immune dysregulation/inflammatory/proliferative conditions. However, T-LGL populations have not been studied in broader spectrum pathologies. In this study we evaluated sizes and correlates of T-LGL populations in the pediatric and young adult populations with various disease states...

BACKGROUND: Cancer risk after long-term exposure to interleukin (IL)-23 inhibitors (IL-23i) and IL-17 inhibitors (IL-17i) remains to be delineated. OBJECTIVE: To evaluate the risk of malignancies in patients with psoriasis treated with IL-23i and IL-17i relative to those prescribed tumor necrosis factor inhibitors (TNFi) during the first 5 years following drug initiation. METHODS: A global population-based cohort study included two distinct analyses comparing patients with psoriasis under different therapeutic modalities; (i) new users of IL-17i(n=15,331) versus TNFi(n=15,331) and (ii) new users of IL-23i(n=5,832) versus TNFi(n=5,832)...

BACKGROUND: Early mortality is a historical measure of the quality of care incorporated into many quality measure algorithms that mostly account for patient comorbidities but do not incorporate disease characteristics and treatment status which independently increase early mortality. This is particularly significant in leukemia, especially in the refractory and salvage settings. STUDY AIM: To define the independent adverse effect of leukemia salvage vs. frontline therapy on early mortality in acute myeloid leukemia (AML) after accounting for the pretreatment independent adverse effects associated with early mortality...
