Background: Antiretroviral therapy (ART) is remarkably effective in preventing perinatal transmission (PT) of HIV-1. We evaluated the PT rate in a population of women with widespread access to ART before conception.
Methods: The analysis included 14 630 women with HIV-1 who delivered from 2000 to 2017 at centers participating in the nationwide prospective multicenter French Perinatal Cohort (ANRS-EPF). PT was analyzed according to time period, timing of ART initiation, maternal plasma viral load (pVL), and gestational age at birth. No infants were breastfed, and all received neonatal prophylaxis.
Results: PT decreased between 3 periods, from 1.1% in 2000-2005 (58/5123) to 0.7% in 2006-2010 (30/4600) and to 0.2% in 2011-2017 (10/4907; P < .001). Restriction of the analysis to the 6316/14 630 (43%) women on ART at conception, PT decreased from 0.42% (6/1434) in 2000-2005 to 0.03% (1/3117) in 2011-2017 (P = .007). Among women treated at conception, if maternal pVL was undetectable near delivery, no PT was observed regardless of the ART combination [95%CI 0-0.07] (0/5482). Among women who started ART during pregnancy and with undetectable pVL near delivery, PT was 0.57% [95%CI 0.37-0.83] (26/4596). Among women treated at conception but with a detectable pVL near delivery, PT was 1.08% [95%CI 0.49-2.04] (9/834). We also qualitatively described 10 cases of transmission that occurred during the 2011-2017 period.
Conclusions: In a setting with free access to ART, monthly pVL assessment, infant ART prophylaxis, and in the absence of breastfeeding, suppressive ART initiated before pregnancy and continued throughout pregnancy can reduce PT of HIV to almost zero.

Background: Viruses that infect prokaryotes (phages) constitute the most abundant group of biological agents, playing pivotal roles in microbial systems. They are known to impact microbial community dynamics, microbial ecology, and evolution. Efforts to document the diversity, host range, infection dynamics, and effects of bacteriophage infection on host cell metabolism are extremely underexplored.

Background: MicroRNAs (miRNAs) are pivotal in the initiation and progression of complex human diseases and have been identified as targets for small molecule (SM) drugs. However, the expensive and time-intensive characteristics of conventional experimental techniques for identifying SM-miRNA associations highlight the necessity for efficient computational methodologies in this field.
Results: In this study, we proposed a deep learning method called Multi-source Data Fusion and Graph Neural Networks for Small Molecule-MiRNA Association (MDFGNN-SMMA) to predict potential SM-miRNA associations.

Algebraic structures play a vital role in securing important data. These structures are utilized to construct the non-linear components of block ciphers. Since constructing non-linear components through algebraic structures is crucial for the confusion aspects of encryption schemes, relying solely on these structures can result in limited key spaces.

This study describes the process of designing and developing the user interface of a digital solution aiming to promote physical and cognitive training (DanceMove) and testing for its usability by community-dwelling older adults. This study is subdivided into four phases: (i) concept and ideation, (ii) design and development of the prototype, (iii) testing of the functional mock-ups, and (iv) testing of the prototype in the laboratory and in the real context of use. Through the different phases of the study technological and healthcare professionals and users were involved.

Purpose: This research presents an experimental study using validated questionnaires to quantitatively assess the outcomes of art-based observational training in medical students, residents, and specialists. The study tested the hypothesis that art-based observational training would lead to measurable effects on judgement skills (tolerance of ambiguity) and empathy in medical students and doctors.
Methods: An experimental cohort study with pre- and post-intervention assessments was conducted using validated questionnaires and qualitative evaluation forms to examine the outcomes of art-based observational training in medical students and doctors.
