The increased consumption of a variety of herbs/supplements has been raising serious health concerns. Owing to an inadequate understanding of herb/supplement–drug interactions, the simultaneous consumption of these products may result in deleterious effects and, in extreme cases, even fatal outcomes. This systematic review is aimed at understanding the knowledge and beliefs about the consumption of herbs/supplements and herb/drug–supplement interactions (HDIs). The study follows the PRISMA guidelines. Four online databases (Web of Science; PubMed; Cochrane; and EBSCOhost) were searched, and a total of 44 studies were included, encompassing 16,929 participants. Herb and supplement consumption is explained mostly by the reported benefits across multiple conditions and ease of use. Regarding HDIs, most people take both herbs/supplements and prescription drugs simultaneously. Only a small percentage of participants have knowledge about their interaction effects, and many reported adverse interactions or side effects. Nevertheless, the main reason for stopping the prescribed drug intake is the perceived lack of its effect, and not due to interactions. Therefore, it is important to increase the knowledge about supplement use so that further strategies can be elaborated to better detect or be alert for whenever a potentially dangerous reaction and/or interaction may occur. This paper raises awareness regarding the need for developing a decision support system and ends with some considerations about the development of a technological solution capable of detecting HDIs and, thereby, aiding in the improvement of pharmacy services.

The use of information and communication technologies (ICTs) has revolutionized the provision of health services, often referred to as eHealth, benefiting community pharmacies that can offer new services in innovative formats, namely through telepharmacy. This study aimed to explore the perceptions of pharmacy professionals (i.e., pharmacists and pharmacy technicians) on the provision of new services. The study consisted of administering an online questionnaire to pharmacy professionals nationwide. The questionnaire was developed by the research team, based on focus group methodology, from which an inductive analysis led to the categories that made up the dimensions of the survey. Participants were 95 pharmacy professionals with a mean age of 33.69 years old (SD = 10.75). Almost 79% were women. The results show overall receptivity to the development of new services in community pharmacies. Suggestions for the development of the new services, conditions necessary for their implementation, potential obstacles, and strategies to promote adherence to the new services, among others, are identified. The knowledge thus acquired will help community pharmacies to develop innovative solutions in counselling, pharmacotherapy monitoring, and pharmacovigilance, for example, of herb/dietary supplement–drug adverse reactions and interactions. Based on this information, new services can become more accessible, namely through the use of ICTs.

Gambling disorder (GD) is associated with deficits in various cognitive functions. Specifically for executive function (EF), previous findings are inconsistent, despite deficits being reported for shifting, inhibition, planning, and working memory domains. Although a worse performance in EF measures related to GD severity is often reported, there is a need to clarify current evidence. This study aims to systematically review and perform a meta-analysis to clarify the association between EF deficits and GD. The current study followed the preferred reporting items for systematic reviews and meta-analyses protocols. The meta-analysis used a random effects model and robust variance estimation to analyze the data, using Hedge’s g to report effect sizes. A total of 21 studies were systematically reviewed, of which 17 were included for meta-analysis. Meta-analysis was performed for shifting, inhibition, planning, and verbal fluency. Due to a lower number of studies, working memory data was systematically reviewed, but no meta-analysis was performed. Significant effect sizes were found for shifting and inhibition, indicative of deficits in participants with GD. No significant deficits were found for the other EF domains. Working memory results revealed inconsistent evidence, even when divided into verbal and visuospatial modalities. There is enough evidence of deficits in shifting and inhibition in participants with GD. However, better sample characterization should be considered in future studies to better understand the sources of potential heterogeneity. Consideration of gambling severity as a continuous variable could allow for a more detailed analysis of EF alterations across the various degrees of GD.

(1) Background: Psoriasis is a common chronic inflammatory skin disease with different manifestations, affecting the quality of life at social, emotional, and professional dimensions and requiring long-term treatment. This study aimed to investigate the effect of psychosocial and clinical factors on adherence to topical treatment in psoriasis. (2) Methods: Self-reported measures and weighing the medicines were used to assess adherence. Psychopathological symptoms were measured using the Brief Symptoms Inventory (BSI). Social and clinical factors were assessed by a sociodemographic and clinical questionnaire. Adherence to treatment with topical medication was assessed using a sample of 102 psoriasis patients. (3) Results: The explanatory models of adherence to topical treatment in psoriasis translated into positive associations between adherence and the education level (higher education) (p = 0.03; φ = 0.23), the single-family household (p = 0.01; φ = 0.44), active employment status (p = 0.05; φ = −0.19), familiar history of psoriasis (p = 0.04; φ = −0.21), and the presence of obsessive-compulsive symptoms (p = 0.01; d = 0.29). (4) Conclusions: In patients who present the characteristics identified that influence non-adherence, instructions should be reinforced to increase adherence. The experimental mortality (39.6%) reduced the sample size, representing a limitation of the study.

Gambling Disorder (GbD) and Gaming Disorder (GmD) are associated with negative consequences that affect personal, social, and professional/academic domains. Although various efforts have been made to prevent and treat both conditions, traditional approaches have limitations, particularly given the technological nature of the environments in which these disorders develop. The aim of this review is to examine the characteristics of Virtual Reality (VR) and Augmented Reality (AR) based interventions for primary and secondary prevention of GbD and GmD. The review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement (PRISMA). A search was conducted across PubMed, Web of Science, Scopus, and EBSCO. Study quality was assessed using the Appraisal Tool for Cross-Sectional Studies (AXIS). Twelve studies (n = 498; 32.1% female) examined VR and AR interventions for GbD and GmD. Multiple VR therapy sessions significantly reduced craving and anxiety in GbD, while educational and self-regulation approaches promoted responsible gambling. In GmD, VR/AR-based interventions reduced symptom severity, gaming time, and negative emotions, improving physical activity and coping skills. Overall, immersive technologies showed consistent therapeutic and preventive benefits across both disorders, enhancing self-regulation and reducing addictive behaviors. The findings support the feasibility, safety, and therapeutic potential of immersive technologies in managing GbD and GmD, although evidence remains insufficient to determine optimal dosage. Future research should focus on long-term interventions with larger and more diverse samples to ensure generalizable results. Studies should also assess the cost-effectiveness of VR and AR as scalable prevention tools for both disorders.
