Boron Nitride Nanosheet-Magnetic Nanoparticle Composites for Water Remediation Applications.

The combination of 0D nanoparticles with 2D nanomaterials has attracted a lot of attention over the last years due to the unique multimodal properties of resulting 0D-2D nanocomposites. In this work, we developed boron nitride nanosheets (BNNS) functionalized with manganese ferrite magnetic nanoparticles (MNPs). The functionalization process involved attachment of MNPs to exfoliated BNNS by refluxing the precursor materials in a polyol medium.

Use of contraindicated antiretroviral drugs in people with HIV/HCV coinfections receiving HCV treatment with direct-acting antivirals-Results from the EuroSIDA study.

Objectives: Our objective was to determine whether antiretroviral drugs (ARVs) were used according to the European AIDS Clinical Society (EACS) guidelines for people with HIV/hepatitis C virus (HCV) coinfection treated with direct-acting antivirals (DAAs) between 30 November 2014 and 31 December 2019 in the pan-European EuroSIDA study.

Methods: At each publication date of the EACS guidelines, plus 3 and 6 months, we calculated the number of people receiving DAAs with potential and actual ARV contraindications ('red shading' in the EACS guidelines). We used logistic regression to investigate factors associated with using contraindicated ARVs.

Evaluation of the impact of human immunodeficiency virus pre-exposure prophylaxis on new human immunodeficiency virus diagnoses during the COVID-19 pandemic.

Aims: The national PrEP programme launched in Ireland in November 2019 with tenofovir/emtricitabine free to those meeting eligibility criteria. We assessed the impact of the first year of the PrEP programme on new HIV diagnoses in the largest sexual health and HIV service in Ireland.

Methods: A free PrEP service was established in November 2019.

CD8 encephalitis with CSF EBV viraemia and HIV drug resistance, a case series.

Introduction: CD8 encephalitis is a relatively recently described condition in the setting of HIV infection. It is becoming increasingly recognised in recent years though is still likely underdiagnosed.

Methods: We present three cases of encephalitis in HIV-positive black African females initially presenting with neurological pathology.

BK polyomavirus associated progressive multifocal leukoencephalopathy in a person living with HIV.

Progressive multifocal leukoencephalopathy (PML) is a rare demyelinating disease of the white matter central nervous system occurring in immunocompromised patients particularly those with T cell deficiency such as in HIV, haematological and solid organ malignancies and those taking immunomodulatory medications. PML is caused by JC virus however in rare cases BK virus has been isolated in the cerebral spinal fluid of patients presenting with PML. In this case we describe a 49 year old man who presented to the emergency department with a 2 week history of progressive right sided weakness and dysarthria.
