Background Although clinical trials reported a low and comparable rate of central nervous system (CNS)/neuropsychiatric (NP) disturbances among people with HIV (PWH) receiving integrase strand transfer inhibitors (INSTI) or other antiretroviral therapy (ART), higher rates of these disturbances have been reported in clinical practice. Our aim was to...

The purpose of the study was to evaluate the therapeutic success and adverse events (AEs) of dalbavancin on-label and off-label use in clinical practice. This was a retrospective, observational, multicentre study that enrolled consecutive patients treated with dalbavancin from January 2017 to May 2024 in the Italian SUSANA cohort. Therapeutic succe...

Objectives Most treatment switches are for simplification from three‐drug (3DR) to dual regimens (2DR). However, a proportion of people with HIV may switch back to 3DR, like bictegravir/emtricitabine/tenofovir alafenamide (B/F/TAF) after 2DR. Methods We included people with HIV enroled in the Icona cohort who switched to B/F/TAF after 2DR INSTI‐ba...

Background/Objectives: The advent of large language models (LLMs), like platforms such as ChatGPT, capable of generating quick and interactive answers to complex questions, opens the way for new approaches to training healthcare professionals, enabling them to acquire up-to-date and specialised information easily. In nursing, they have proven to su...

Non-fermenting Gram-negative bacteria (NFGNB) are a heterogeneous group of opportunistic pathogens increasingly associated with healthcare-associated infections. While Pseudomonas aeruginosa, Acinetobacter baumannii, and Stenotrophomonas maltophilia are well known, rarer species such as Burkholderia cepacia complex, Achromobacter spp., Chryseobacte...

Objectives: Large language models (LLMs) show promise in clinical decision-making, but comparative evaluations of their antibiotic prescribing accuracy are limited. This study assesses the performance of various LLMs in recommending antibiotic treatments across diverse clinical scenarios. Methods: Fourteen LLMs, including standard and premium versi...

Modern ART is evolving, allowing the use of new drug formulations and alternative routes of administration to oral therapy. Long-acting (LA) cabotegravir and rilpivirine, the first fully injectable antiretroviral regimen approved for clinical use, is a test case for this new route of administration, and an innovation with implications for the quali...

Background Females with HIV (FWH) are underrepresented in HIV trials. Pooled data from 5 trials at 48 weeks demonstrated the virological efficacy and safety of bictegravir/emtricitabine/tenofovir alafenamide (B/F/TAF). We evaluated the safety and efficacy of B/F/TAF in a cohort of 99 FWH, in a real-life setting, at 48 and 96 weeks from the switch....

Background: Biofilm-associated infections frequently span multiple body sites and represent a significant clinical challenge, often requiring a multidisciplinary approach involving surgery and antimicrobial therapy. These infections are commonly healthcare-associated and frequently related to internal or external medical devices. The formation of b...

Background/Objectives: Out of 39.9 million adults living with HIV in 2022, 20 million were women. Despite bearing a significant burden, women remain underrepresented in clinical trials, including those for antiretroviral treatments (ART). This study evaluates the safety and efficacy of the bictegravir/emtricitabine/tenofovir alafenamide (B/F/TAF) r...

Background and Clinical Significance: Tuberculosis (TB) poses a significant global health challenge; although low–middle income countries carry the heaviest burden, its diagnosis and treatment can be challenging in any country. The clinical picture can be complex and vary from person to person, with autoimmune complications that can hinder TB diagn...

Background: Nurses play a pivotal role in combating antimicrobial resistance (AMR).

We read with interest the work by D’arminio Monforte et al.,¹ evaluating the long-term risk of treatment failure of dolutegravir-based regimens. In their study, the authors found no difference in treatment failure by sex but observed a higher risk of discontinuation due to toxicity in women. Tolerability of dolutegravir, which has become one of the...

After 40 years of its appearance, human immunodeficiency virus (HIV) infection remains a leading public health challenge worldwide. Since the introduction of antiretroviral treatment (ART), HIV infection has become a chronic condition, and people living with HIV could have life expectancies close to those of the general population. People with HIV...

Background Doravirine (DOR) is a newly approved antiretroviral belonging to the class of non-nucleoside reverse transcriptase inhibitors (NNRTI), well tolerated and leading to an improved lipid profile in antiretroviral experienced people living with HIV (PLWH).

In 2014, UNAIDS launched renewed global targets for HIV control to achieve by 2025, known as “the three 95”: 95% of people living with HIV (PWH) diagnosed, of which 95% are receiving treatment, of which 95% are on sustained virological suppression. In Italy, new HIV diagnoses have been steadily decreasing since 2012. However, in 2020, 41% of new di...

Since the start of the SARS-CoV-2 pandemic, several scores have been proposed to identify infected individuals at a higher risk of progression and death. The most famous is the 4C score. However, it was developed in early 2020. Our study aimed to evaluate the accuracy of the 4C score during the wave in which the Omicron variant was prevalent. An ob...
