Efficacy and safety of antiviral therapies for the treatment of persistent COVID-19 in immunocompromised patients since the Omicron surge: a systematic review.

Background: Persistent COVID-19 (pCOVID-19) in immunocompromised patients is characterized by unspecific symptoms and pulmonary infiltrates due to ongoing severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) replication. Treatment options remain unclear, leading to different approaches, including combination therapy and extended durations. The purpose of this study was to assess the efficacy and safety of antiviral therapies for pCOVID-19 in immunocompromised patients since the Omicron surge.

Reliability and validity of four cognitive interpretation bias measures in the context of social anxiety.

People with social anxiety disorder tend to interpret ambiguous social information in a negative rather than positive manner. Such interpretation biases may cause and maintain anxiety symptoms. However, there is considerable variability in the observed effects across studies, with some not finding a relationship between interpretation biases and social anxiety.

The Topology of Poly(2-methyl-2-oxazine) Shells on Nanoparticles Determines Their Interaction with Serum and Uptake by Immune Cells.

Cyclic poly(2-methyl-2-oxazine) (-PMOZI) brush shells on Au nanoparticles (NPs) exhibit enhanced stealth properties toward serum and different cell lines compared to their linear PMOZI (-PMOZI) counterparts. While selectively recruiting immunoglobulins, -PMOZI shells reduce overall human serum (HS) protein binding and alter the processing of complement factor 3 (C3) compared to chemically identical linear shells. Polymer cyclization significantly decreases NP uptake by nonphagocytic cells and macrophages in both complement-deficient fetal bovine serum (FBS) and complement-expressing HS, indicating ineffective functional opsonization.

Evaluation of deprescribing services in frail patients: a systematic review.

Background: Deprescribing, a process of dose reduction or withdrawal of inappropriate medication that no longer has benefit, is a proposed intervention in the care of older adults living with frailty.

Objective/aim: To evaluate the safety, effectiveness, and clinical impact of deprescribing services in frail patients.

Methods: A systematic literature search was performed in November 2023 using Scopus, CINAHL PLUS (EBSCO), MEDLINE (OVID and EMBASE), and Cochrane Library.

Cultivation and molecular characterization of viable Helicobacter pylori from the root canal of 170 deciduous teeth of children.

Background: Helicobacter pylori is a persistent pathogen in the human stomach. However, the proposed transmission route via the oral cavity is not understood and under intense debate. While dozens of studies have shown by PCR that H.
