Histoplasmosis is a systemic infection caused by an endemic dimorphic fungus, Histoplasma capsulatum. Though prevalent in the eastern United States of America, near the Ohio and Mississippi River Valleys, the evidence underlying the global prevalence of histoplasmosis, especially in immunocompromised populations, is underappreciated. This article highlights the global epidemiology, risk factors, microbiology and pathophysiological characteristics, pulmonary and extrapulmonary manifestations, prevention measures, radiographic patterns, diagnostic techniques, and antifungal treatment approaches for Histoplasma capsulatum.

Review Case Reports
Splenic artery embolization complicated by pleural effusion.
This case report and review describes a 31-year-old man with a history of chronic pancreatitis who presented to the hospital with shortness of breath and left-sided chest pain. Three days prior, he underwent mid-splenic artery embolization due to hematemesis attributed to a splenic artery pseudoaneurysm associated with a peripancreatic pseudocyst. Upon this presentation, the patient reported increasing shortness of breath, left-sided pleuritic chest pain, and epigastric and left upper quadrant abdominal pain. ⋯ The pleural effusion was attributed to recent splenic artery embolization, and the patient was discharged on appropriate medications in stable condition on the sixth day of hospitalization. This case underscores the importance of considering embolization-related complications in the differential diagnosis of pleural effusions following such procedures. The etiology, diagnosis, and management of splenic artery aneurysms are discussed in this review.

The intricate biological mechanism underlying lung adenocarcinoma (LUAD), characterized by a deficiency of distinctive biomarkers, remain elusive. The presence of Long non-coding RNAs (lncRNAs) have been established to play a role in carcinogenesis. Nevertheless, the regulatory effects and mechanisms of lncRNA CYTOR in LUAD have yet to be elucidated. ⋯ These findings demonstrated that lncRNA CYTOR acted as an oncogene in LUAD, regulating tumor malignant progression through the miR-503-5p/PCSK9 axis. This study unveiled a new regulation mechanism of LUAD progression, offering potential therapeutic targets for LUAD.

Diabetic kidney disease (DKD; also known as diabetic nephropathy) is a typical complication of diabetes mellitus characterised by renal injury due to disturbances in glucose metabolism, in which renal tubular damage caused by chronic inflammation has been shown to be closely associated with the development of end-stage renal disease (ESRD). However, there are insufficient effective therapeutic agents to halt the progression of DKD. ⋯ These results highlight that the target compound SB-525334 could serve as a novel potential therapeutic agent and ameliorate DKD in an inflammation-inhibiting manner.
