Background: The Video Interaction Project (VIP) is a healthcare-based intervention that provides real-time video-feedback of parent-child play and reading interactions to families with children aged 0 to 36 months. Although evidence from randomized controlled trials demonstrates improved early relational health, including responsive parenting, after three to five VIP visits, the minimal effective dose in real-world implementations is unknown. This study aimed to determine the minimal effective dose of VIP during a real-world implementation for changing responsive parenting behaviors.
Methods: We performed a longitudinal prospective study of 183 dyads at a public hospital pediatric clinic. Responsive parenting behaviors were assessed with an observational checklist utilized as part of standard VIP practice at baseline and two follow-up VIP visits.
Results: Multilevel models adjusted for baseline sociodemographics (child's sex and age, and maternal education) and time between visits showed that responsive parenting behaviors during parent-child reading and play significantly increased after a single VIP visit (Cohen's d = 0.52, p < 0.05) with additional impact following completion of a second visit (cumulative for 2 visits: d = 0.76, p < 0.05).
Conclusions: A single VIP visit is associated with increased responsive parenting behaviors. Findings support offering VIP widely, regardless of capacity to ensure attendance at multiple visits.
Impact: This is the first study showing the minimal effective dose of the Video Interaction Project (VIP) for increasing responsive parenting behaviors. Responsive parenting behaviors increased by over 22% following a single VIP visit, with a cumulative increase of 37% following the second visit compared to baseline. Findings have important implications for implementation and scalability of pediatric-based preventive programs that support early relational health through activities such as reading and play.

Depressed mothers often experience parenting difficulties, which can persist after their symptoms have remitted. However, not all depressed mothers show parenting struggles, suggesting that there could be unidentified characteristics that increase risk. Specifically, neurobiological models emphasize that reward system deficits contribute to maladaptive parenting and depression, but no studies have evaluated how they could conjointly lead to parenting challenges.

Background: Differentiating between primary and permanent teeth is a critical component of oral health knowledge, influencing both preventive care and clinical decisions. With the growing use of artificial intelligence (AI) in healthcare and education, its role in supporting learning is of increasing interest.
Aim: This study evaluated the diagnostic accuracy and internal consistency of ChatGPT-4.

This study investigates learning transfer processes in the teaching of pure tacts and intraverbals within the context of verbal behavior. The objectives were: to assess whether training pure tacts and intraverbals, through the inclusion of different stimuli, facilitates learning transfer to new impure tacts, and to determine whether one of these verbal operants (pure tact or intraverbal) better promotes learning transfer. The sample included 54 children aged 11-12 years, using a within-subjects experimental design with pre-post measures.

The present study focuses on the phenotypic characterization of several mutants of Flavobacterium psychrophilum, obtained from a transposon mutant library. This Gram-negative bacterium is the etiological agent of the "cold water disease", pathology that usually affects salmonids, mainly Oncorhynchus mykiss. This microorganism is considered a "fastidious bacterium" due to the difficulty to isolate it.

Paclitaxel resistance is a major obstacle to achieving long-term remission in patients with triple-negative breast cancer (TNBC), and effective strategies to overcome drug resistance would have significant clinical impact. In this study, we established a paclitaxel-resistant cell clone, T50R, from the human TNBC cell line MDA-MD-231. Intriguingly, these drug-resistant T50R cells required paclitaxel for proliferation.
