Article The Effects of Lactobacillus and/or Bifidobacterium in Fermented Foods on Cognitive Health: A Systematic Review(Frontiers Media SA, 2025) Harsa, Hayriye Sebnem; Gonzalez Domenech, Carmen Maria; Prvulovic, Milica; Agirbasli, Zeynep; Bagherzadehsurbagh, Erfan; Simeunovic, Valentina; Pracer, SmiljaBackground: Psychobiotics are microorganisms that modulate brain function via the gut-brain axis and are increasingly studied for their cognitive benefits. Lactobacillus and Bifidobacterium species, widely present in fermented foods, are considered safe and may influence cognition by modulating neuroinflammation, neurotransmitters, and gut barrier integrity. This systematic review examined the effects of foods fermented with these species on cognitive performance in healthy adults and individuals with mild cognitive impairment. Methods: We conducted the systematic review following EFSA guidelines, Cochrane methodology, and a PROSPERO protocol, using CADIMA for study selection and data extraction. PubMed, Scopus, and Cochrane Library were searched (1 January 1970-31 August 2023) for human intervention and observational studies assessing cognitive outcomes after ingestion of foods fermented with Lactobacillus or Bifidobacterium. Eligible populations included healthy adults and individuals with mild cognitive impairment; studies involving disease were excluded. Screening, data extraction, and bias assessment followed Muka et al.'s 24-step guide using ROBINS and Cochrane/CADIMA frameworks. Evidence was synthesized narratively, while a non-systematic component examined food characteristics, potential mechanisms, and factors affecting bioavailability of bioactive constituents. Results: We included 21 studies (8 interventional, 13 observational). The majority of studies reported benefits, particularly in episodic memory, executive functions, and global cognition, but evidence was limited by inadequate controls, small sample sizes, short interventions, inconsistent domain assessment, and incomplete food characterization. Observational studies had larger populations and longer follow-ups but were limited by exposure assessment and depth of cognitive testing. Conclusion: Consumption of foods fermented with Lactobacillus and/or Bifidobacterium species may offer promising cognitive benefits. However, following EFSA's guidance on the substantiation of health claims, the current evidence is "neither convincing nor sufficient" to establish a causal relationship. Well-designed studies with thorough product characterization are needed to substantiate effects and support potential health claims.Article Efficacy of Fermented Foods for the Prevention and Treatment of Bacterial Vaginosis and Vulvovaginal Candidiasis(Frontiers Media SA, 2025) Akpinar, A.; Markiewicz, L.H.; Harsa, H.S.; Paveljšek, D.; Domínguez-Soberanes, J.; Agirbasli, Z.; Karakaş-Budak, B.Vaginal function in healthy women is closely associated with a lactobacilli-dominated microbiome. Among the most common conditions arising from dysbiosis are bacterial vaginosis (BV) and vulvovaginal candidiasis (VVC). While the efficacy of oral probiotics for the treatment of BV and VVC is well documented, the role of consuming fermented foods remains underexplored. This systematic review aims to present a systematic evaluation of the potential role of fermented foods in the prevention and treatment of BV and VVC and establish the extant research gap between the realm of the clinical sciences and the field of food science and technology. For this purpose, under the guidance of COST Action CA20128—Promoting Innovation of Fermented Foods (PIMENTO), a systematic literature review was conducted in two phases. PubMed, Scopus, and Cochrane databases were used for Phase I to analyze articles on human trials and observational studies where the intervention/exposure involved oral consumption of fermented food. In Phase II, a two-step search strategy was employed: (i) identifying microorganisms with demonstrated clinical efficacy in managing BV and VVC, and (ii) reviewing food science literature where these strains are utilized for fermentation. It was observed that 87% of the food starter applications exploited only two of the 54 efficacious strains identified through clinical studies, namely Lactobacillus rhamnosus GG and Lactobacillus acidophilus LA-5. Findings underscore the potential of fermented foods as carriers for beneficial microorganisms and their relevance in supporting vaginal health. This review contributes to a deeper understanding of the interplay between nutritional consumption of viable probiotic strains and their importance in immunomodulation, highlighting the need for more integrated research efforts across disciplines. Future research aimed at filling this gap will enable informed clinical decisions and dietary recommendations. © © 2025 Akpınar, Markiewicz, Harsa, Paveljšek, Domínguez-Soberanes, Agirbasli, Naziri, El Jalil, Bouchaud, Salminen, Savary-Auzeloux, Humblot, Chassard, Pracer, Vergères and Karakaş-Budak.Article Chemosensitizing Effect of Apigenin on T-ALL Cell Therapy(Frontiers Media SA, 2025) Huseynova, N.; Baran, Z.; Khalilov, R.; Mammadova, A.; Baran, Y.T-cell acute lymphoblastic leukemia (T-ALL) is an aggressive hematological malignancy with limited therapeutic options and frequent treatment-associated toxicities. L-asparaginase, a cornerstone in T-ALL therapy, is often restricted by hypersensitivity reactions and systemic side effects, highlighting the need for safer strategies to enhance its efficacy. This study investigated the potential of apigenin, a naturally occurring flavonoid with antioxidant and pro-apoptotic properties, to act as a chemosensitizer for L-asparaginase in MOLT-4 T-ALL cells. Cytotoxicity was assessed using the MTT assay, apoptosis by Annexin V/PI staining, cell cycle distribution by flow cytometry, and mitochondrial membrane potential by JC-1 staining. Both apigenin and L-asparaginase produced dose- and time-dependent cytotoxicity, with combination treatment resulting in reduced IC<inf>50</inf> values. Apoptotic analysis showed significantly higher apoptosis in the combination-treated groups than in single-agent groups. Cell cycle analysis revealed that apigenin induced S-phase arrest and L-asparaginase induced G1-phase arrest, while the combination disrupted cell cycle progression at multiple checkpoints. JC-1 assay further demonstrated enhanced mitochondrial depolarization, with up to a 29.2-fold increase in cytoplasmic-to-mitochondrial fluorescence ratio in combination therapy compared to L-asparaginase alone. These findings indicate that apigenin potentiates L-asparaginase-induced cytotoxicity through mitochondrial dysfunction and intrinsic apoptotic signaling. The combined use of apigenin and L-asparaginase may provide a novel strategy to improve therapeutic efficacy in T-ALL while potentially reducing the toxicity associated with high-dose L-asparaginase monotherapy. © © 2025 Huseynova, Baran, Khalilov, Mammadova and Baran.Article Impact of Yogurt Consumption on Bone Health Markers in Adults with or without Osteoporosis: A Systematic Review and Meta-Analysis(Frontiers Media SA, 2025) Mayo, B.; Malagón-Rojas, J.; Agahi, F.; Frias, J.; Künili, İ.E.; Kütt, M.-L.; Tamang, J.P.Yogurt is a fermented dairy product widely recognized for its nutritional value and potential health benefits, particularly due to its high content of calcium, phosphorus, vitamins, and other bioactive compounds. Its purported role in promoting bone health has attracted increasing attention, especially among adults at risk of osteoporosis. However, the specific impact of yogurt consumption on bone health remains controversial, as current evidence is limited and often inconclusive. This systematic review and meta-analysis sought to evaluate the exclusive effects of yogurt consumption on bone health in adults with and without osteoporosis. Employing rigorous inclusion and exclusion criteria and standardized methodologies, the study reviewed data from both observational and clinical studies to assess the effect of yogurt consumption on bone mineral density (BMD), fracture risk, and other bone health markers. In addition, yogurt characteristics were documented in accordance with EFSA guidelines, the possible bioactive components listed, and their potential mechanism of action in relation to bone health discussed. Studies fitting the inclusion and exclusion criteria (n = 12) were all observational, limiting the ability to infer causality. The meta-analysis of cohort studies (n = 6) found no significant association between yogurt consumption and hip fracture risk (HR = 1.01, 95% CI: 0.96–1.07), while the observed positive effect on BMD was minimal and clinically irrelevant (SMD = 0.009). Although some studies reported modest improvements in BMD and bone biomarkers, the overall evidence remains inconclusive, hindered by the heterogeneity in study designs and inconsistent yogurt intake. In conclusion, current evidence does not support a significant role of yogurt consumption in preventing fractures or improving BMD in adults. Well-designed randomized controlled studies are needed to clarify its effects, particularly in adults at risk of or with osteoporosis or osteopenia. In conclusion, the effectiveness of yogurt as a primary strategy for enhancing bone health is not fully substantiated by current data, though its inclusion within a balanced diet may still offer benefits for bone health.

However, the release of the Barbie 2023 Movie has shifted our focus from Barbie to Ken, marking the first occasion when Barbie has provided a platform for exploring representations of masculinity both in the patriarchal society and in popular culture. This article aims to investigate how the 2023 Barbie movie deconstructs symbols of hegemonic and toxic masculinity and its performative aspects within the framework of (post)feminist discourse. It examines how the movie satirically employs symbols of traditional, hegemonic masculinity to challenge normative masculine ideals prevalent in our patriarchal society. The movie -through its popularity- significantly contributes to mainstream postfeminist media culture, creating a platform where discussions on masculinity, its associated crises, and the broader gender wars, along with their existential ramifications, become unavoidable. Exploring the ways masculinities are problematized and contested within postfeminist media culture, I argue that Ken, within this narrative, is positioned as the latest icon of postfeminist masculinity, symbolizing a critical juncture in the ongoing discourse on gender roles and identities.
