Infarcts and ischemia in the abdomen: an imaging perspective with an emphasis on cross-sectional imaging findings.

Infarcts and ischemia of abdominal organs may present with acute abdominal pain, and early diagnosis is crucial to prevent morbidity and mortality. Unfortunately, some of these patients present in poor clinical conditions to the emergency department, and imaging specialists are crucial for optimal outcomes. Although the radiological diagnosis of abdominal infarcts is often straightforward, it is vital to use the appropriate imaging modalities and correct imaging techniques for their detection. Additionally, some non-infarct-related abdominal pathologies may mimic infarcts, cause diagnostic con

Emerging trends and disparities in mortality due to coexisting non-Hodgkin's lymphoma and respiratory infections: A U.S. nationwide retrospective analysis from 1999 to 2020.

Non-Hodgkin lymphoma (NHL) patients are highly susceptible to respiratory infections due to immunosuppression from both the disease and its treatments. Understanding mortality trends and disparities in this population is crucial for improving care and reducing the burden of coexisting conditions. This study analyzed death certificates from the Center of Disease Control Wide-Ranging Online Data for Epidemiologic Research database for individuals aged ≥ 25 years who died between 1999 and 2020 with both NHL and respiratory infections. Age-adjusted mortality rates (AAMRs) and annual percent change

A clinician survey for management of the secondary immunodeficiency caused by hematological malignancies in China.

AbstractUnlike Western countries, there are still few clinical immunology specialists in China, and the optimal care for secondary immunodeficiency caused by hematological malignancies is unknown. Therefore, we initiated this clinician survey study to describe the current situation of the care for malignancy patients with hypogammaglobulinemia in China.We adapted a previously published online questionnaire of current clinical practices regarding the management of secondary immunodeficiency caused by hematological malignancies and then distributed the questionnaire to 52 hematologists in China

Mantle Cell Lymphoma Presenting as Acute Abdominal Syndrome: A Rare Case Report and Literature Review.

BACKGROUND: Acute abdominal syndrome can be caused by several possible reasons. The most common causes are perforation of a gastroduodenal ulcer, peritonitis, intestinal obstructions, and perforation of an appendix or fallopian tube. Fever and pain can be caused by an appendicitis or sigmoiditis. Appendiceal lymphoma is a rare disease that is usually found incidentally during appendectomy. Most of the cases are non-Hodgkin's lymphomas. Mantle cell lymphoma is an aggressive B-cell non-Hodgkin's lymphoma with a poorer prognosis than other B-cell lymphomas; thus, a definitive diagnosis is essenti

Senescent T cells: Beneficial and detrimental roles.

As the thymus involutes during aging, the T-cell pool has to be maintained by the periodic expansion of preexisting T cells during adulthood. A conundrum is that repeated episodes of activation and proliferation drive the differentiation of T cells toward replicative senescence, due to telomere erosion. This review discusses mechanisms that regulate the end-stage differentiation (senescence) of T cells. Although these cells, within both CD4 and CD8 compartments, lose proliferative activity after antigen-specific challenge, they acquire innate-like immune function. While this may confer broad i

Nephrotoxicity in Bispecific Antibodies Recipients: Focus on T-Cell-Engaging Bispecific Antibodies.

Recently, bispecific antibodies (BsAbs) are evolving the landscape of cancer treatment and have significantly improved the outcomes of relapsed or refractory cancer patients. As increasing BsAbs entered clinical practice, specific toxicities have emerged, and renal side-effects have been described. However, there are a lack of studies analyzing the nephrotoxicity in the anti-cancer BsAbs recipients systematically. In this review, we demonstrate the etiologies, mechanisms, other risk factors and treatment options of kidney injury in the BsAbs recipients to provide a more comprehensive insight i

Improved intensive care unit survival for critically ill allogeneic haematopoietic stem cell transplant recipients following reduced intensity conditioning.

The use of allogeneic haematopoietic stem cell transplantation (Allo-HSCT) is a standard treatment option for many patients with haematological malignancies. Historically, patients requiring intensive care unit (ICU) admission for transplant-related toxicities have fared extremely poorly, with high ICU mortality rates. Little is known about the impact of reduced intensity Allo-HSCT conditioning regimens in older patients on the ICU and subsequent long-term outcomes. A retrospective analysis of data collected from 164 consecutive Allo-HSCT recipients admitted to ICU for a total of 213 admission

Cancer-associated stroke: Pathophysiology, detection and management (Review).

Numerous types of cancer have been shown to be associated with either ischemic or hemorrhagic stroke. In this review, the epidemiology and pathophysiology of stroke in cancer patients is discussed, while providing vital information on the diagnosis and management of patients with cancer and stroke. Cancer may mediate stroke pathophysiology either directly or via coagulation disorders that establish a state of hypercoagulation, as well as via infections. Cancer treatment options, such as chemotherapy, radiotherapy and surgery have all been shown to aggravate the risk of stroke as well. The clin

Clinical Utility of Frailty Scoring in Elderly Acute Myeloid Leukemia Patients Treated With Venetoclax and Hypomethylating Agents.

Acute myeloid leukemia (AML) in elderly patients presents a major therapeutic challenge, as many are deemed unfit for intensive chemotherapy due to age, comorbidities, or frailty. Venetoclax in combination with hypomethylating agents (HMA) has emerged as a standard-of-care for this population, yet outcomes remain heterogeneous and predictive tools are limited. In this retrospective single-center study, we analyzed 52 treatment-naïve AML patients receiving venetoclax combined with either azacitidine (n = 33) or decitabine (n = 19) at the Hematology Department of Cosenza Hospital between August

Systemic Sclerosis Association with Malignancy.

The association of systemic sclerosis (SSc) and cancer is well known from several decades suggesting common genetic and environmental risk factors involved in the development of both diseases. Immunosuppressive drugs widely used in SSc may increase the risk of cancer occurrence and different SSc clinical and serological features identify patients at major risk to develop malignancy. In this context, among serological features, presence of anti-RNA polymerase III and anti-topoisomerase I autoantibodies seems to increase cancer frequency in SSc patients (particularly lung and breast cancers).

A Rapid Review of Adenocarcinoma and Pulmonary Tumor Thrombotic Microangiopathy: A Deadly Duo.

Pulmonary tumor thrombotic microangiopathy (PTTM) is a rare paraneoplastic syndrome associated with various adenocarcinomas, most commonly gastric adenocarcinoma. This condition can progressively worsen pulmonary arterial hypertension, leading to acute or subacute pulmonary heart failure and respiratory insufficiency. This paper examines the pathogenesis, clinical presentation, diagnosis, treatment, and prognosis of PTTM. Given PTTM's poor prognosis, we emphasize treatment strategies. PTTM in adenocarcinoma patients can mimic other pulmonary diseases, causing diagnostic delays. Current PTTM tr

From Lab to Clinic: Success Stories of Repurposed Drugs in Treating Major Diseases.

Optimal Delivery of Follow-Up Care After Allogeneic Hematopoietic Stem-Cell Transplant: Improving Patient Outcomes with a Multidisciplinary Approach.

The increasing indications for allogeneic stem-cell transplant in patients with hematologic malignancies and non-malignant diseases combined with improved clinical outcomes have contributed to increase the number of long-term survivors. However, survivors are at increased risk of developing a unique set of complications and late effects, besides graft-versus-host disease and disease relapse. In this setting, the management capacity of a single health-care provider can easily be overwhelmed. Thus, to provide appropriate survivorship care, a multidisciplinary approach for the long-term follow-up
