A Novel Fusion in a Poorly Differentiated Carcinoma Involving the Lung and Mediastinum.

Cancer genetics studies have dramatically advanced the understanding of the molecular drivers in various types of neoplasms. This progress is also leading to the discovery of more new molecular agents to block those drivers, which has significantly improved cancer patient survival, especially in non-small cell lung cancer (NSCLC). However, in about 25% of NSCLC tumors molecular drivers are not yet known.

Management challenge of a rare concomitant platelet glycoprotein IV/CD36 and IIb/IIIa deficiencies: Case illustration.

Introduction/background: Platelet membrane glycoproteins (GPs) serve several functions, the most significant of which is their role in primary hemostasis. Among these, GP IIb/IIIa is the primary fibrinogen receptor and is essential for platelet aggregation. Its deficiency or dysfunction impairs platelet aggregation, leading to Glanzmann thrombasthenia, a rare autosomal recessive bleeding disorder.

Hemolysis due to anti-IH in a patient with beta-thalassemia and infection.

Anti-IH is a common cold agglutinin that is typically clinically insignificant. We present a case that resulted in hemolysis. A 32-year-old male patient with transfusion-independent beta-thalassemia intermedia presented with symptomatic anemia.

Evaluation of Archival HIV DNA in Brain and Lymphoid Tissues.

HIV reservoirs persist in anatomic compartments despite antiretroviral therapy (ART). Characterizing archival HIV DNA in the central nervous system (CNS) and other tissues is crucial to inform cure strategies. We evaluated paired autopsy brain-frontal cortex (FC), occipital cortex (OCC), and basal ganglia (BG)-and peripheral lymphoid tissues from 63 people with HIV.

Sex Differences in CMV Replication and HIV Persistence During Suppressive ART.

Background: The association between subclinical cytomegalovirus (CMV) replication and HIV persistence has not been investigated in cis-gender women with HIV.

Methods: Fifty virologically suppressed female participants with HIV were prospectively enrolled and provided oral, vaginal, and urine samples and peripheral blood mononuclear cells at 1 cross-sectional time point. CMV DNA was quantified in each specimen by real-time polymerase chain reaction (PCR).

Longitudinal Viral Dynamics in Semen During Early HIV Infection.

Background: Multiple viruses coinfect the male genital tract, influencing each other’s replication and perhaps affecting human immunodeficiency virus (HIV) pathogenesis and disease progression.

Methods: This study included 453 longitudinal seminal samples from 195 HIV-infected men from the San Diego Primary Infection Resource Consortium and 67 seminal samples from HIV-negative healthy controls. Seminal HIV RNA and DNA from 7 human herpesviruses (HHVs) were measured by real-time polymerase chain reaction.
