Background: Lung transplantation is an important treatment option for various end-stage lung diseases. However, survival remains limited due to graft rejection and infections. Despite that fungal infections are frequent and carry a bad prognosis, there is currently no consensus on efficacy, optimal drug, route, or duration of antifungal prophylaxis. This narrative review summarizes current strategies for antifungal prophylaxis after lung transplantation.
Methods: English language articles in Embase, Pubmed, UptoDate, and bibliographies were used to assess the efficacy and safety of available antifungal agents for prophylaxis in adult lung transplant recipients.
Results: Overall, there are limited high-quality data. Universal prophylaxis is more widely used and may be preferable over targeted prophylaxis. Both formulations of inhaled amphotericin B and systemic azoles are effective at reducing fungal infection rates, yet with their own specific advantages and disadvantages. The benefit of combination regimens has yet to be proven. Considering the post-transplant timing of the onset of fungal infections, postoperative prophylaxis during the first postoperative months seems indicated for most patients.
Conclusions: Based on existing literature, universal antifungal prophylaxis with inhaled amphotericin B and systemic voriconazole for at least 3-6 mo after lung transplantation may be advisable, with a slight preference for amphotericin B because of its better safety profile.

Fungal Infections in Kidney Transplant Recipients: A Comprehensive Narrative Review.
Microorganisms
January 2025
Infectious and Tropical Diseases Unit, Padua University Hospital, 35128 Padua, Italy.
Background: Despite kidney transplantation being a life-saving procedure, patients experience a high risk of developing fungal infections (FIs), with an increased risk of both morbidity and mortality, especially during the first year after transplant.
Methods: We herein conducted a narrative review of the most common FIs in kidney transplant recipients (KTRs), with a focus on prevalence, risk factors, mortality, and prevention strategies.
Results: The most common fungal pathogens in KTRs include species (up to 70% of the overall FIs), species, , and species.
Investigation of Betaine and Vaccine Efficacy for Coccidiosis Prevention in Broilers.
Acta Parasitol
January 2025
Department of Parasitology, Faculty of Veterinary Medicine, Aydin Adnan Menderes University, Aydin, Turkey.
Purpose: This study aimed to assess the anticoccidial effects of betaine and a vaccine compared to monensin sodium in experimentally induced coccidiosis in broiler chickens.
Methods: 600 day-old broiler chickens (Ross 308) were randomly assigned to five groups, each with four replicates of 30 birds. While the control group received a basal diet, two experimental groups received basal diet supplemented with either 100 mg/kg monensin sodium or 2.
Fungal Biocontrol Agents in the Management of Postharvest Losses of Fresh Produce-A Comprehensive Review.

Postharvest decay of vegetables and fruits presents a significant threat confronting sustainable food production worldwide, and in the recent times, applying synthetic fungicides has become the most popular technique of managing postharvest losses. However, there are concerns and reported proofs of hazardous impacts on consumers' health and the environment, traceable to the application of chemical treatments as preservatives on fresh produce. Physical methods, on the other hand, cause damage to fresh produce, exposing it to even more infections.

Introduction: Posaconazole is recommended for prophylaxis in pediatric immunocompromised patients. Due to its variability in bioavailability and drug-to-drug interactions, EBMT recommends regimens based on therapeutic drug monitoring (TDM).
Materials And Methods: In total, 171 oncohematological pediatric patients on posaconazole prophylaxis were included.

Botrytis cinerea is the causal agent of gray mold, which is one of the most widespread and destructive fungal diseases that compromises the productivity and quality of grapes produced throughout the world. This work aimed to verify, for the first time, the impact of unencapsulated carvacrol and encapsulated in Eudragit® nanocapsules (Eud-Carv NCs) and chia mucilage (Chia-Carv NCs) on mycelial growth and spore germination of B. cinerea.
