This study investigates how neuromarketing practices intersect with consumer privacy regulation in California, with particular attention to the 2024 Senate Bill 1223 (SB 1223), which amends the CCPA/CPRA to explicitly define “neural data.” By examining corporate strategies and regulatory frameworks, the paper evaluates how firms navigate the tension between innovation, ethics, and consumer protection. A qualitative, multiple-case study approach was adopted, focusing on Coca-Cola, Frito-Lay, and Hyundai. Data were collected from corporate privacy policies, industry publications, and legislative documents, triangulated through doctrinal legal analysis and cross-case synthesis. The analysis reveals that, while companies comply with disclosure, consent, and oversight requirements under the CCPA/CPRA, such compliance remains largely procedural, with transparency often being technical rather than consumer-friendly, consent being insufficiently informed, and protections for vulnerable groups being inconsistently enforced. SB 1223’s recent definition of neural data directly encompasses techniques such as EEG, fMRI, eye-tracking, and biometrics, underscoring the urgent need for firms to treat neuromarketing as a category of regulated practice rather than discretionary innovation. The study is limited by its reliance on publicly available documentation and by the recency of SB 1223, which precludes observation of mature compliance patterns. Future research should explore consumer perceptions, track evolving regulatory responses, and extend the analysis across various sectors, including healthcare, education, and non-profits. This study contributes to theory by extending stakeholder theory to neural data governance and by conceptualizing neuromarketing as a governance-intensive strategic capability situated at the frontier of consumer rights and technological innovation. It contributes to practice by demonstrating how firms can transform compliance with emerging neural data regulations into a strategic capability that strengthens consumer trust, ethical legitimacy, and brand equity.

Background/Objectives: Long-distance running often requires athletes to carry their own hydration. Both the velocity of the runner and the load will affect the ground reaction forces (GRFs). Furthermore, carrying a liquid mass may have different outcomes on GRF compared to carrying a solid mass. This effect may in turn potentially result in a greater risk of injury. The goal of this study was to examine the GRF while jogging with different quantities of water in a hydration pack. It was expected that GRF measures would change with increased hydration pack weight. Methods: Twenty college-aged participants were asked to run over a force plate with an empty hydration pack and packs (0.71 kg) filled with 0.5 litres (1.21 kg), 1.5 litres (1.71 kg), and 2.5 litres (3.21 kg) of water. Results: No significant differences (p > 0.05) in the vertical, lateral, or forward–back measures were found between the different loads. These outcomes may be a result of the dampening effect the movement of the water may have on gait. Conclusions: It is believed that the benefit of having hydration readily available via a hydration pack will outweigh any potential for injury due to the added weight being carried. Full article

The traditional use of medicinal plants around the world has a long history, predominantly in low- and middle-income countries. Previous ethnobotanical research pertaining to urban environments demonstrated that the legacy of the use of medicinal plant species persists worldwide; however, information about the main city in the occidental part of Mexico is scarce regarding this traditional knowledge and its variation during the last few decades. A database was created from interviews with local people who had inhabited the oldest neighborhoods of Guadalajara for at least 30 years and by using different electronic databases. In addition, the correct taxonomic identification of species was supported via corroboration through local and other digital herbariums. Furthermore, a Principal Coordinate Analysis (PCoA) was performed on the database information to search for relationships among the medicinal plant species used. An inventory of 137 medicinal plants was created, where the plant species most commonly used in the five old neighborhoods of Guadalajara City were muicle (Justicia spicigera Schltdl.), pirul (Schinus molle L.), manzanilla (Matricaria chamomilla L.), valeriana (Valeriana sp.), calabaza (Cucurbita pepo L.), cola de caballo (Equisetum arvense L.), tepezcohuite (Mimosa tenuiflora Poir.), salvia (Salvia officinalis L.), canela (Cinnamomum verum J. Presl.), tila estrella (Tilia americana var. mexicana (Schltdl.) Hardin), cedrón (Aloysia citrodora Paláu), uva (Vitis vinifera L.), jengibre (Zingiber officinale Roscoe) and gobernadora (Larrea tridentata (DC.) Coville). Illnesses of the cardiovascular, digestive, urinary, respiratory, nervous, muscular and reproductive systems, as well as culture-bound syndromes, were mostly treated with these plant species. Moreover, J. spicigera, M. chamomilla and L. tridentata were used for eight medical purposes, followed by Z. officinale with five medicinal practices. In contrast, only two medicinal uses were recorded for C. pepo, M. tenuiflora and S. officinale. The PCoA explained 65.88% of the variation accumulated at the first three ordination axes and formed four groups of species, which were related to their geographical origin. Eight of the fourteen species that are commonly used as medicinal plants are from America, and the rest come from Europe and Asia. This study confirms the persistence of traditional knowledge related to medicinal plants, and the diseases empirically addressed among the inhabitants of Guadalajara City are common in other parts of the world and in different regions of Mexico. These findings are supported by electronic databases that comprise multiple studies related to the phytochemical compounds and medical validation regarding their biological activity, supporting the empirical use and efficacy of these medicinal plants.

Clear orthodontic aligners, primarily composed of thermoplastic polymers, are increasingly popular but susceptible to degradation through thermal, chemical, and mechanical stress. This preliminary pilot study assessed the release of microplastics from two commercial aligner brands under simulated oral conditions. Aligners were exposed to daily cycles of Coca-Cola^® or artificial saliva, with mechanical agitation replicating masticatory friction. Fourier-transform infrared spectroscopy confirmed microplastic release in both environments, with a notably higher particle count after Coca-Cola^® exposure. These findings indicate the potential health and environmental risks linked to acidic beverage consumption during orthodontic treatment. Further comprehensive studies are required to validate and expand upon these results. Full article

Biomimetic restorative dentistry aims to preserve tooth structure and achieve optimal aesthetic harmony with surrounding dentition. The principles and protocols associated with biomimetic restorative dentistry are designed to enhance the longevity of the restoration. The use of flowable CRs is increasingly common; however, the effect of viscosity on the discoloration has not been clearly established. This in vitro study aimed to assess the color stability of flowable CRs with varying viscosities following immersion in common staining solutions and subsequent repolishing. A total of 250 disc-shaped specimens (8 mm × 2 mm) were prepared from five CRs with different viscosity profiles: high-viscosity (Spectra STHV, Dentsply, Milford, DE, USA), medium-viscosity (Estelite Universal Flow Medium, Tokuyama Dental Co., Tokyo, Japan), bulk-fill (Estelite Bulk-Fill Flow, Tokuyama Dental Co., Tokyo, Japan; SDR Plus, Dentsply, Milford, DE, USA), and packable (Estelite Posterior, Tokuyama Dental Co., Tokyo, Japan). After polymerization and baseline color measurements, specimens were immersed in coffee, tea, cola, red wine, or distilled water for 144 h. Color values were recorded before and after staining, and again following repolishing. Color changes (ΔE₁, ΔE₂, ΔE₃) were calculated using the CIE Lab system and statistically analyzed via two-way ANOVA and Tukey HSD (α = 0.05). Both the CR type and the staining solution substantially affected the color change. SDR Plus exhibited the highest ΔE values. Red wine caused the most discoloration. Repolishing enhanced color in selected groups. Full article

Introduction: The decline of serum estrogen in postmenopausal women leads to several changes in the vulvovaginal and vesicourethral areas, resulting in the genitourinary syndrome of menopause (GSM), characterized by bothersome symptoms such as vaginal atrophy, lack of lubrication, dyspareunia, urgency, dysuria, and recurrent urinary tract infections. Nevertheless, this condition could also be experienced by younger women affected by hormone-dependent tumors. Although topical estrogens are considered “the gold standard”, hormonal treatments cannot be indicated in cancer survivors. As a result, energy-based devices using radiofrequency and laser technologies have emerged as alternative options. This prospective study aimed to evaluate the benefits of non-invasive monopolar radiofrequency (RF) in women affected by GSM who have contraindications to, did not respond to, or declined local estrogen therapy. Methods: The patients underwent five weekly sessions of second-generation monopolar RF. At baseline and at the fifth session, two validated questionnaires were administered to the patients: the Visual Analogue Scale (VAS) and the Female Sexual Function Index (FSFI-19). On the other hand, the vaginal mucosa status was evaluated by clinicians through the Vaginal Health Index (VHI). At the end of the cycle, the Patient Global Impression of Improvement (PGI-I) questionnaire was collected. Results: Based on 44 patients who completed five sessions of radiofrequency, a significant improvement was observed in sexual function according to the FSFI scale (22.9 vs. 38.6; p < 0.001) and in VVA atrophy symptoms, as documented by the VAS score (223 vs. 125; p < 0.001). The mean VHI score increased by 3 points (p < 0.001). Moreover, according to PGI-I, 96% of patients reported a perceived improvement (PGI-I score ≤ 3). Conclusions: Radiofrequency could provide an innovative and safe therapeutic approach for patients suffering from GSM and VVA, especially when hormonal strategies are unsuitable. Full article

This exploratory study investigated how health concerns related to chronic environmental contamination and how satisfaction with the human biomonitoring (HBM) process influence the perceived quality of life in the context of per- and polyfluoroalkyl substances (PFAS) contamination in the Veneto Region (Italy). We administered a questionnaire to 84 residents of the Red Area, where PFAS exposure is classified as most severe. The main findings revealed that satisfaction with HBM was positively correlated with perceived quality of life and showed a statistically significant but modest moderation effect on the relationship between PFAS-related health concerns and quality of life (explaining 17.4% of the variance). Particularly, it attenuates the negative effect that PFAS health concerns have on quality of life. Differences between subgroups revealed heightened concern regarding PFAS health risks among women vs. men and participants with children vs. those without. These results underscore the central role of relational and communication aspects of HBM programs to mitigate psychological distress and possibly contribute to higher perceived well-being. The study highlights the need for tailored public health interventions, including transparent communication, empathetic support, and community engagement, to address the psychosocial dimensions of environmental contamination.

Polycystic liver disease (PLD) is a rare genetic disorder characterized by the development of >10 fluid-filled cysts in the liver. While PLD can occur in isolation, it is most commonly associated with autosomal dominant polycystic kidney disease, adding complexity to its management. PLD is often asymptomatic but can lead to hepatomegaly, causing symptoms such as abdominal distension, pain and discomfort, early satiety, gastroesophageal reflux, and malnutrition, ultimately affecting patients’ quality of life. Current treatment strategies, including pharmacological and interventional approaches, focus on reducing liver volume and alleviating symptoms. However, management remains largely symptomatic, as no definitive therapies exist to halt cyst progression. Liver transplantation is the only curative option for patients with severe, progressive disease and refractory complications. The EASL guidelines recognize that PLD-related symptoms, primarily due to hepatomegaly, can contribute to involuntary weight loss and recommend assessing symptomatic patients for malnutrition and sarcopenia. Although evidence suggests that patients with PLD may be at risk of malnutrition, original data on the quality and extent of nutritional alterations remain scarce. The potential influence of nutrition on disease progression, symptom burden, and overall well-being is also largely unexplored. Given these knowledge gaps, addressing nutritional challenges, such as early satiety, is essential for optimizing symptom management and maintaining overall nutritional status. This review outlines a possible pathophysiology of malnutrition, specific dietary considerations and recommendations, and weight management in patients with PLD. Additionally, dietary complexities in patients with concurrent renal involvement are discussed, offering a practical framework for clinicians and dietitians in managing this challenging condition.

Trichomes in cannabis (Cannabis sativa L.) are specialized structures responsible for cannabinoid and terpene biosynthesis, making their density a critical parameter for both research and industrial applications. However, consistent trichome density assessment remains challenging due to anatomical variability and the absence of standardized methodologies. This review critically examines the existing literature on trichome quantification across key floral structures—such as bracts, sugar leaves, calyxes, and the main cola—to identify the most reliable sites and practices for accurate evaluation. Evidence suggests that bracts represent the most consistent sampling unit, given their homogeneous trichome distribution and elevated cannabinoid concentration. Whilst sugar leaves and calyxes are also frequently analyzed, their morphological variability requires cautious interpretation. Furthermore, trichome shape, size, maturity, and vegetal surface expansion/shrinkage during stress must be considered when correlating density with secondary metabolite production. We also highlight the advantages of using more than only one floral structure and integrating microscopic imaging and software-assisted analysis to enhance reproducibility and accuracy. By synthesizing current methodologies and proposing pathways for standardization, this review aims to support more robust trichome assessment protocols, ultimately improving cannabinoid yield optimization, quality control, broader cannabis research frameworks, and an important aesthetic parameter for consumers. Future research efforts should focus on advancing imaging methodologies and optimizing sampling protocols to further improve the precision and reproducibility of trichome density and cannabinoid analyses.

This study systematically investigates microplastic (MP) release from polypropylene (PP) and polylactic acid (PLA) straws across beverage matrices (deionized water, cola, and skim milk) under thermal variations. A laboratory simulation system was developed to quantify MP release at ambient temperature (25 °C) and characterize size reduction across thermal gradients (25 °C, 45 °C, and 65 °C). The integrated analytical approaches combining Fourier-transform infrared spectroscopy (FTIR), micro-FTIR, scanning electron microscopy (SEM), and optical microscopy were employed to systematically quantify and characterize MPs in terms of abundance, morphological features, and polymer composition. The findings reveal that PP straws released significantly higher MP quantities (26–28 particles/straw) than PLA counterparts (18–26 particles/straw) at 25 °C, with a pronounced burst release phase occurring within the initial 5 min of usage of straws. Thermal escalation experiments demonstrated progressive MP size reduction for both PP and PLA groups, with elevated temperatures inducing particles into smaller particles. Full article

Pelvic organ prolapse (POP) is a common pelvic floor disorder with substantial impact on women’s quality of life, necessitating accurate and reproducible diagnostic methods. This study investigates the use of three-dimensional (3D) transperineal ultrasound, integrated with artificial intelligence (AI), to evaluate pelvic floor biomechanics and identify correlations between biometric parameters and prolapse severity. Thirty-seven female patients diagnosed with genital prolapse (mean age: 65.3 ± 10.6 years; mean BMI: 29.5 ± 3.8) were enrolled. All participants underwent standardized 3D transperineal ultrasound using the Mindray Smart Pelvic system, an AI-assisted imaging platform. Key biometric parameters—anteroposterior diameter, laterolateral diameter, and genital hiatus area—were measured under three functional states: rest, maximal Valsalva maneuver, and voluntary pelvic floor contraction. Additionally, two functional indices were derived: the distensibility index (ratio of Valsalva to rest) and the contractility index (ratio of contraction to rest), reflecting pelvic floor elasticity and muscular function, respectively. Statistical analysis included descriptive statistics and univariate correlation analysis using Pelvic Organ Prolapse Quantification (POP-Q) system scores. Results revealed a significant correlation between laterolateral diameter and prolapse severity across multiple compartments and functional states. In apical prolapse, the laterolateral diameter measured at rest and during both Valsalva and contraction showed positive correlations with POP-Q point C, indicating increasing transverse pelvic dimensions with more advanced prolapse (e.g., r = 0.42 to 0.58; p < 0.05). In anterior compartment prolapse, the same parameter measured during Valsalva and contraction correlated significantly with POP-Q point AA (e.g., r = 0.45 to 0.61; p < 0.05). Anteroposterior diameters and genital hiatus area were also analyzed but showed weaker or inconsistent correlations. AI integration facilitated real-time image segmentation and automated measurement, reducing operator dependency and increasing reproducibility. These findings highlight the laterolateral diameter as a strong, reproducible anatomical marker for POP severity, particularly when assessed dynamically. The combined use of AI-enhanced imaging and functional indices provides a novel, standardized, and objective approach for assessing pelvic floor dysfunction. This methodology supports more accurate diagnosis, individualized management planning, and long-term monitoring of pelvic floor disorders. Full article

This exploratory study presents the first metagenomic assessment of the gut microbiome in domestic cats from Cali, Colombia. Fecal samples were collected from 10 healthy, sterilized domestic cats, aged 8 months to over 2 years, with variation in sex (7 females, 3 males), diet (processed or raw), and outdoor access (5 with, 5 without). Using 16S rRNA gene metabarcoding and pooled shotgun metagenomic sequencing, the study characterized the taxonomic composition and functional potential of the feline gut microbiome. Dominant phyla included Bacillota and Bacteroidota, with substantial inter-individual variation. Peptoclostridium was the most consistently abundant genus, while Megamonas and Megasphaera showed higher variability. Shotgun analysis detected antibiotic resistance genes (ErmG, ErmQ) and virulence factors (pfoA, plc, colA, nanJ, nagI) in Clostridium perfringens, highlighting potential zoonotic risk. The composition of the gut microbiota was influenced primarily by diet and outdoor access, while age and gender had more moderate effects. The study concludes that lifestyle and environmental factors play a key role in shaping the gut microbiome of domestic cats. We recommend further longitudinal and larger-scale studies to better understand the dynamics of feline microbiota and their implications for animal and public health within a One Health framework.

Background/Objectives: The nutritional importance of grain-based foods (GBFs) and whole grains (WGs) is underscored by their central position in dietary guidance worldwide. Many jurisdictions recommend consumers increase WG intake because they are associated with multiple health benefits, with evidence quality rated as moderate to high. High intakes of ultra-processed foods (UPFs), as defined by NOVA that classifies food by level of processing, are associated with numerous negative health outcomes, with evidence less convincing than for WGs. Yet, some dietary guidance recommends consumers to avoid UPFs. This creates two divergent guidelines since NOVA designates most commonly eaten grain-based foods (GBFs) as UPFs. These contradictory guidelines fail to comply with recommended principles of dietary guidance and generate questions about underlying assumptions and definitions that classify WG staples and colas together. Methods: Definitions and assumptions for systems ostensibly categorizing foods by level of processing were evaluated for validity by various methods. Special attention was paid to the ability of different classifications to differentiate between WGs, RGs staples, and indulgent GBFs. Findings from meta-analyses associating high intakes of WGs with numerous health benefits were compared with those associating high intakes of UPFs. Menus and modeling studies were assessed for ability to meet recommendations for WGs and the grain food group with customary GBFs while avoiding UPFs. Advice to “avoid UPFs” was tested against principles for effective dietary guidance. Results: Definitions and categorizations of foods by levels of processing vary markedly. Assumptions for NOVA and other systems are questionable. While meta-analyses consistently show high intakes of UPFs are associated with adverse health outcomes, high intake of WG foods, nearly all designated as UPFs, are associated with better health outcomes, although evidence quality for the latter is rated stronger. These findings add to the body of evidence suggesting flawed assumptions behind categorizing WG staples in terms of level of processing. Conclusions: NOVA deems 90% of WGs as UPFs. Adding statements to dietary guidance to “Avoid UPFs”, while asking consumers to increase WG intakes, confuses. Further, it jeopardizes efforts to increase intake of fiber and WG foods because it excludes top sources of fiber and WG-based breads, rolls, tortillas, or cold cereals in Western diets. NOVA advice to avoid UPFs challenges principles for usable dietary guidance and the construction of culturally appropriate, healthy dietary patterns containing WG staples from all levels of processing.

Stress urinary incontinence (SUI) is a common condition that can significantly impair a woman’s quality of life. While initial management includes conservative treatments, surgical options are recommended in refractory cases. Suburethral slings are currently one of the most widely recommended surgical treatments due to their high long-term efficacy. However, complications such as postoperative urinary retention can occur and may lead to chronic voiding dysfunction when not promptly diagnosed and managed. Background/Objectives: The aim of this study was to evaluate the long-term voiding function in women undergoing delayed sling removal or incision for neglected chronic voiding dysfunction. Methods: This retrospective study examined women with chronic voiding dysfunction occurring at least one year after suburethral sling placement for SUI. Preoperative evaluation included comprehensive history, physical examination, urethral ultrasound, uroflowmetry, and urodynamic studies. Surgical interventions consisted of partial or complete sling removal or sling incision (unilateral or bilateral). Postoperative follow-up was conducted at one month and then at 12 months, including clinical examination, ultrasound, and symptom assessment. Results: Sixteen patients were included in the study, all of whom presented with urodynamic confirmation of voiding dysfunction. Following surgical intervention, a significant improvement was observed in voiding symptoms and overall symptoms (p < 0.01). Notably, only one patient experienced persistent voiding difficulties, although complete symptom remission was achieved following sacral neuromodulation. Conclusions: Sling removal or incision has proven to be an effective approach in resolving the majority of cases of neglected chronic voiding dysfunction. These findings suggest that, when appropriately performed, surgical intervention can substantially alleviate symptoms and improve patient well-being, providing an effective therapeutic option for what is often a debilitating condition.

Patients’ attitude toward therapy and adherence to treatment are central in determining the long-term outcomes of medical treatment in ulcerative colitis. A complex interplay of differing factors modulates the likelihood of persisting in or discontinuing treatment, including patients’ beliefs and concerns about adverse effects of drugs, as well as the interactions with medical staff. Emotional attitude and expectancies are reflected in the so-called placebo and nocebo effects which influence patients’ choices to adhere to or discontinue treatment. They represent important confounding factors in clinical trials and are amplified when the evaluation relies on patient-reported outcomes more than on objective measurements. The therapeutic gain related to placebo effects is likely also relevant in day-to-day practice, but few data are available. The aim of the present narrative review is to provide critical insight into the adherence to therapy in ulcerative colitis and its interaction with the emotional component of the effects of therapy, resulting in the placebo/nocebo effects. Understanding the mechanisms underlying patient behavior may help identify the most appropriate therapeutic approach and treatment schedule to optimize adherence and outcomes in individual patients with UC.
