Certain open access publishers based on the article processing charges model have found it highly profitable to operate within a gray zone that encompasses both legitimate and predatory publishing practices. In this context, maximum profits can be obtained by adequate combinations of journal acceptance rates and elevated article processing charges. Considering that the gray zone can be particularly challenging to identify and that it poses risks for authors aiming to establish academic carreers, we believe it is important to provide a comprehensive description of it.

Double-negative (DN) T cells represent a small and phenotypically heterogeneous population that display regulatory functions. In HIV infection, DN T cells are decreased in peripheral blood and have been negatively associated with T cell activation. This study was aimed at describing the dynamics and phenotypic characteristics of DN T cells in peripheral blood of people living with HIV (PLHIV) before and after antiretroviral therapy (ART) initiation.

Article Synopsis
  • This study aimed to compare the effectiveness of two adjuvant therapies, cidofovir and bevacizumab, in controlling recurrent respiratory papillomatosis (RRP) after surgical resection.
  • A randomized pilot study involved five children and eleven adults with RRP, who were assigned to receive one of the treatments or a placebo following surgery, with their progress monitored over a year.
  • Results indicated that cidofovir led to a significant reduction in RRP severity, but no conclusive effectiveness was found for bevacizumab, and both treatments showed a general improvement in voice quality.

Objectives: After surgical resection of papilloma, adjuvant therapy may be recommended for the control of recurrent respiratory papillomatosis (RRP). As the efficacy of adjuvant therapy remains unproven, the aim of this study was to compare the efficacy of cidofovir versus bevacizumab used as adjuvant therapies for the control of RRP.

Methods: This randomized, double-blind, placebo-controlled pilot study was performed in a national respiratory disease referral centre.

Background: The platelet endothelial cell adhesion molecule-1 (PECAM-1) or CD31 has been involved in regulation of T-cell tolerance, activation, survival and homing in mice cells. However, there is limited knowledge about the expression pattern and role of this molecule in human T cells, particularly in conditions of chronic immune activation.

Objectives: We explored CD31 expression in T cell differentiation subsets of individuals with untreated HIV infection and in non-HIV-infected controls.

Due to the lack of therapeutic options for patients with progressive multifocal leukoencephalopathy-associated immune reconstitution inflammatory syndrome (PML-associated IRIS), maraviroc has generated expectations among the medical community. However, we report a patient with advanced HIV infection, who developed PML-associated IRIS and had a fatal outcome despite the addition of maraviroc to suppressive ART. Future studies are required to define the therapeutic role of maraviroc in PML-associated IRIS and differentiate individuals who may benefit from maraviroc from those who may develop neurological deterioration.
