Late Recurrence of Prosthetic Valve Endocarditis Due to Candida albicans.

BACKGROUND Candida prosthetic valve endocarditis is a rare disease that is increasing in incidence with the rising rates of fungemia and increased use of intracardiac devices. Chronic antifungal prophylaxis is used after primary treatment to prevent recurrence, but the optimal duration of prophylaxis is currently unknown. This case report is of a woman with a history of mitral valve replacement due to Candida endocarditis presenting 2 years later with prosthetic valve and native aortic valve Candida albicans endocarditis.

Reprogramming Short-Chain Fatty Acid Metabolism Mitigates Tissue Damage for Streptococcus pyogenes Necrotizing Skin Infection.

Disease Tolerance (DT) is a host response to infection that limits collateral damage to host tissues while having a neutral effect on pathogen fitness. Previously, we found that the pathogenic lactic acid bacterium manipulates DT using its aerobic mixed-acid fermentation (ARMAF) pathway via the enzyme pyruvate dehydrogenase (PDH) to alter expression of the immunosuppressive cytokine IL-10. However, the microbe-derived molecules that mediate communication with the host's DT pathways remain elusive.

Inositol phosphorylceramide synthase null Leishmania are viable and virulent in animal infections where salvage of host sphingomyelin predominates.

Many pathogens synthesize inositol phosphorylceramide (IPC) as the major sphingolipid (SL), differing from the mammalian host where sphingomyelin (SM) or more complex SLs predominate. The divergence between IPC synthase and mammalian SL synthases has prompted interest as a potential drug target. However, in the trypanosomatid protozoan Leishmania, cultured insect stage promastigotes lack de novo SL synthesis (Δspt2) and SLs survive and remain virulent, as infective amastigotes salvage host SLs and continue to produce IPC.

Predicting pharmacy students' intention to apply for a residency: A systematic theory of planned behavior approach.

Objective: The current literature has identified many motivating factors and barriers influencing pharmacy students' decision to apply for residency training. Despite a growing need for residency trained pharmacists to advance the profession, it is not clear why only about one in four pharmacy students decide to pursue a residency, and which of these factors have the most influence on student decision-making. The study examines the factors associated with pharmacy students' intention to apply for a postgraduate residency using the theory of planned behavior (TPB) framework.

Tilting the balance between RNA interference and replication eradicates Leishmania RNA virus 1 and mitigates the inflammatory response.

Many Leishmania (Viannia) parasites harbor the double-stranded RNA virus Leishmania RNA virus 1 (LRV1), which has been associated with increased disease severity in animal models and humans and with drug treatment failures in humans. Remarkably, LRV1 survives in the presence of an active RNAi pathway, which in many organisms controls RNA viruses. We found significant levels (0.
