Temporal Trends of Fungal Infections in Cirrhotic Patients: A Retrospective Cohort Study 2016-2020.
J Clin Exp Hepatol
December 2024
Stanford University, Palo Alto, CA, United States.
Background: Patients with cirrhosis are susceptible to infections due to abnormalities in humoral and cell-mediated immunity. Fungal infections are associated with delayed diagnosis and high mortality rates, emphasizing the importance of performing fungal cultures and maintaining elevated levels of suspicion in this patient population.
Methods: This retrospective cohort study analyzes cirrhotic patients readmitted with bacterial and fungal infections and investigates outcomes, including in-hospital mortality and hospital resource utilization.
Inactivation of antibiotic resistant bacteria by nitrogen-doped carbon quantum dots through spontaneous generation of intracellular and extracellular reactive oxygen species.

The widespread antibiotic resistance has called for alternative antimicrobial agents. Carbon nanomaterials, especially carbon quantum dots (CQDs), may be promising alternatives due to their desirable physicochemical properties and potential antimicrobial activity, but their antimicrobial mechanism remains to be investigated. In this study, nitrogen-doped carbon quantum dots (N-CQDs) were synthesized to inactivate antibiotic-resistant bacteria and treat bacterial keratitis.

Traditional cereal vinegars are fermented by microorganisms that are spontaneously enriched, leading to uncertainty in regulating the fermentation process and flavor. The objective of this study was to elucidate the impact of the predominant microorganisms, provenly and , on the solid-state fermentation (SSF) and flavor profile of cereal vinegar by several bioaugmentation strategies. The results indicated that the sequential bioaugmentation of predominant microorganisms improved the utilization of raw material and most key flavor compounds.

It has been established that cross-fostering impacts the development of hypertension in spontaneously hypertensive rats (SHR). However, the ability of the cross-fostering protocol to shape gut microbiota profile in SHR and impact hypertension is not known. In this sense, the current study explored the influence of normotensive and hypertensive postnatal environments on the intestinal microbiota structure, composition, and functional capacity of SHR and Wistar rats.

Recent times have witnessed revolutionary progress in the design and development of functionalized nanomaterials as promising tools for biomedicinal applications. However, the gap in the fundamental understanding of the "biological responses" of the nanomaterials after the formation of "protein-corona" when it is exposed to the body system has drawn a thin line from its discoveries to real clinical trial. In this article we have synthesized two different silver NPs capped with the polyphenols of (guava) leaf extract and the other with one of its major polyphenolic groups, morin.
