Pharmacokinetics of Antiretroviral Drugs in Older People Living with HIV, Part II: Drugs Licensed Before 2005.

Background And Objective: Advances in antiretroviral therapy led to an increase in life expectancy among people living with human immunodeficiency virus (HIV). As aging is characterized by several physiological changes that can influence pharmacokinetics (PK), this systematic review aims to describe the impact of aging on the PK of antiretrovirals (ARV) approved by the Food and Drug Administration (FDA) before 2005.

Methods: Searches were performed in BVS, EMBASE, and PubMed databases for publications until June 2024.

Increased consumption of ultra-processed foods during pregnancy is associated with sociodemographic, behavioral, and obstetric factors: A cohort study.

A diet based on ultra-processed food (UPF) does not meet nutritional needs, especially during pregnancy. The aim of this study is to assess the change in UPF consumption from preconception to pregnancy and associated factors. Our hypothesis is that women tend to adopt a healthier eating pattern during pregnancy, decreasing the intake of UPF and increasing the intake of unprocessed/minimally processed foods.

Estradiol and Spironolactone Plasma Pharmacokinetics Among Brazilian Transgender Women Using HIV Pre-Exposure Prophylaxis: Analysis of Potential Interactions.

Background And Objective: An important barrier to HIV prevention among transgender women (TGW) is the concern that oral pre-exposure prophylaxis (PrEP) negatively affects the efficacy of feminizing hormone therapy (FHT). We aimed to assess the impact of PrEP on FHT pharmacokinetics (PK) among TGW from Brazil.

Methods: We performed a drug-drug interaction sub-study among TGW enrolled in a daily oral PrEP demonstration study (PrEParadas, NCT03220152).

Vitreoretinal Surgery in Uveitis: From Old to New Concepts - A Review.

Purpose: The aim of this article is to do a comprehensive literature review about the current role of pars plana vitrectomy in uveitis and in its different structural complications such as cystoid macular edema, epiretinal membrane, macular hole, and retinal detachment.

Methods: This comprehensive literature review was performed based on a search on PubMed, BioMed Central, Science Open, and CORE databases, of relevant articles abording pars plana vitrectomy in uveitis.

Discussion: Uveitis is a complex disease with multiple etiologies and pathogenic mechanisms.

Neurobrucellosis.

Purpose Of Review: Brucellosis is one of the most common zoonosis worldwide, affecting 500 000 people, annually. Neurobrucellosis incidence is approximately 4%, and it is almost always heterogeneous. As there are no typical clinical features, its diagnosis is frequently misdiagnosing by other infections.

Impact of feminizing hormone therapy on tenofovir and emtricitabine plasma pharmacokinetics: a nested drug-drug interaction study in a cohort of Brazilian transgender women using HIV pre-exposure prophylaxis.

Objectives: Potential interactions between feminizing hormone therapy (FHT) and pre-exposure prophylaxis (PrEP) may be a barrier to PrEP use among transgender women (TGW). We aimed to assess the impact of FHT on PrEP plasma pharmacokinetics (PK) among TGW.

Methods: This was a PK substudy of the effects of FHT on tenofovir disoproxil fumarate/emtricitabine nested to a trans-specific PrEP demonstration study (NCT03220152).

Optical Coherence Tomography Findings in Infectious Posterior Uveitis.

Purpose: To describe and illustrate the main optical coherence tomography (OCT) findings of infectious uveitis.

Methods: Narrative review.

Results: Posterior segment OCT in patients with infectious uveitis reveals posterior hyaloid face precipitates, superficial retinal precipitates and infiltrates, foveolitis, retinitis, neuro-retinitis, choroidal granulomas, and choroiditis as main imaging biomarkers.

Human immunodeficiency virus and intraocular inflammation in the era of highly active anti retroviral therapy - An update.

Intraocular inflammation in patients with human immunodeficiency virus (HIV) infection is commonly due to infectious uveitis. Ocular lesions due to opportunistic infections (OI) are the most common and have been described extensively in the pre highly active antiretroviral therapy (HAART) era. Many eye lesions were classified as acquired immunodeficiency syndrome (AIDS) defining illnesses.

Post-fever retinitis - Newer concepts.

Post-fever retinitis (PFR) is an infectious or para-infectious uveitic entity caused by bacterial or viral agents and seen mainly in tropical countries. Systemic symptoms such as joint pain, skin rash are common during the febrile stage. On the basis of only clinical presentation, it is difficult to pin-point the exact etiology for PFR.

Neurological Aspects of HIV-1/HTLV-1 and HIV-1/HTLV-2 Coinfection.

Simultaneous infection by human immunodeficiency viruses (HIV) and human T-lymphotropic viruses (HTLV) are not uncommon since they have similar means of transmission and are simultaneously endemic in many populations. Besides causing severe immune dysfunction, these viruses are neuropathogenic and can cause neurological diseases through direct and indirect mechanisms. Many pieces of evidence at present show that coinfection may alter the natural history of general and, more specifically, neurological disorders through different mechanisms.

HTLV-1 Associated Neurological Complex. What is Hidden below the Water?

The human T-cell lymphotropic virus type 1 (HTLV-1) infects 5-10 million people worldwide and causes fatal and disabling diseases in a significant proportion of them. A chronic myelitis named HTLV-1 associated myelopathy/tropical spastic paraparesis (HAM/TSP) is the typical neurological manifestation of HTLV-1. However, other neurological syndromes can be either associated with HAM/TSP or occur in isolation in the HTLV-1 infected individual.

Seroprevalence of antibodies against the three serotypes of poliovirus and IPV vaccine response in adult solid organ transplant candidates.

Objectives: To assess the prevalence of protective antibody titers to polioviruses in adults candidates for solid organ transplant (SOT), and to assess the immunogenic response to inactivated polio vaccine in this population.

Methods: The study included SOT candidates referred to Immunization Reference Centre of Evandro Chagas National Institute of Infectious Diseases from March 2013 to January 2016. It was conducted in 2 phases.

Chlamydia trachomatis, Neisseria gonorrhoeae and syphilis among men who have sex with men in Brazil.

Background: Sexually transmitted diseases (STD) are frequently asymptomatic and increase the likelihood of transmitting and acquiring HIV. In Brazil, the guidelines for STDs diagnosis and treatment are based on the syndromic approach. Nucleic acid amplification tests (NAAT) has been recommended as routine STDs screening in some countries, especially for men who have sex with men (MSM).
