Consumers' Categorizations of Dairy Products and Plant-Based Milk, Yogurt, and Cheese Alternatives.

Plant-based dairy alternatives have many benefits in terms of sustainability, animal welfare, and health, but they can only be successful in the market if consumers perceive them as suitable substitutes for conventional dairy. Consumers' expectations for new products are strongly influenced by the food categories into which they place these products. The present study aims to reveal consumers' categorizations of plant-based dairy products to gain insights into their potential as dairy substitutes. In a free sorting task, 100 participants from the German-speaking part of Switzerland sorted a variety of plant-based and conventional animal-based dairy products into groups, indicating their spontaneous similarity perceptions. Additionally, we assessed the participants' characteristics and attitudes toward plant-based dairy products to test potential differences in categorization strategies among consumer groups. Multidimensional scaling and cluster analysis showed that consumers' mental representations of plant-based dairy and conventional animal-based dairy were clearly separated across a wide range of product types. This pattern was even observed among consumers who ate less meat, had higher exposure to vegan dietary styles, and had less negative attitudes toward dairy alternatives. The results suggest that taxonomic distinctions based on plant or animal origin dominate consumers' perceptions and are likely to hinder the substitution of dairy with plant-based dairy. Nevertheless, they also imply that plant-based products that manage to emphasize shared goals and functional properties akin to conventional dairy products are more likely to form a common goal-derived category in consumers' minds and thus have better prospects as substitutes.

World Allergy Organization (WAO) Diagnosis and Rationale for Action against Cow's Milk Allergy (DRACMA) guidelines update - XVI - Nutritional management of cow's milk allergy.

Cow's milk allergy (CMA) is one of the most common presentations of food allergy in early childhood. Management of CMA involves individualized avoidance of cow's milk and other mammalian milk and foods containing these. Optimal elimination of cow's milk avoidance includes: label reading; information about safe and nutritious substitute foods; appropriate choice of infant formula or a plant-based food; establishing tolerance to baked milk and monitoring nutritional intake and growth. Substitute formulas are divided into soy formula (not hydrolyzed), milk-based extensively hydrolyzed formulas, rice based extensive, and partially hydrolyzed formulas and amino acid-based formulas. The use of other mammalian milks is not recommended for the management of cow's milk allergy due to a high level of cross-reactivity and nutritional concerns. For toddlers who are eating well, children, and adults, a suitable plant-based beverage may be a suitable alternative to a specialized formula, following careful nutritional considerations. Families need to be instructed on finding suitable nutritious foods and how to prepare suitable meals at home. Individuals with CMA also need to know how to identify and treat acute severe reactions.

Comprehensive Study of Total Nitrogen Content and Microfluidic Profiles in Additive-Enriched Plant-Based Drinks.

The growing consumption of plant-based milk substitutes raises important questions about their composition. The various additives used by manufacturers, including those employed as flavor enhancers, protein additives, and stabilizers, may contain both protein and non-protein nitrogen components. In our study, we examined not only popular milk alternatives but also other milk substitutes made from specific plants. We present a reproducible and rapid method for the simultaneous qualitative and quantitative determination of the total nitrogen content in milk alternatives, focusing on applicability. Using the microchip gel electrophoretic method, we determined that the total nitrogen content differed from the protein content indicated on the packaging. Our results, along with statistical evaluations, supported the hypothesis that different brands of products, derived from the same plant source, resulted in different microfluidic profiles, likely due to the presence of additives. As expected, the microfluidic profiles of additive-free products differed from those of fortified products made from the same plant-based milk replacer. Total nitrogen content provides crucial information for individuals with kidney disease, as is essential to reduce the burden on the kidneys to slow deterioration, alleviate symptoms and avoid complications.

Study on the Pyrolysis and Fire Extinguishing Performance of High-Temperature-Resistant Ultrafine Dry Powder Fire Extinguishing Agents for Aviation Applications.

Ultrafine KAl(OH)2CO3 dry powder (UDWP), as a novel high-temperature-resistant ultrafine dry powder fire extinguishing agent, has garnered significant attention in the field of aviation fire protection. However, its development has been hindered by its hydrophilicity, which leads to hygroscopicity, and its tendency for re-ignition due to oil deposition. Therefore, this study employs perfluorodecyltrimethoxysilane (PFDTMS) to modify the surface of UDWP, resulting in hydrophobic and oleophobic M-UDWP. The thermal stability and hydrophobicity of M-UDWP ensure its long-term stable storage in aircraft equipment compartments, thereby reducing aircraft maintenance costs. Additionally, its oleophobicity provides excellent anti-re-ignition performance, protecting aircraft power compartments from secondary fire damage. Energy-dispersive X-ray spectroscopy (EDS), Fourier-transform infrared spectroscopy (FTIR), and X-ray photoelectron spectroscopy (XPS) analyses indicate that the PFDTMS modifier was successfully grafted onto KAl(OH)2CO3. Furthermore, M-UDWP exhibits a three-stage thermal decomposition process. The first-stage decomposition can be regarded as a single-step reaction, and the calculated kinetic parameters provide accurate predictions. Thermogravimetric analysis-Fourier transform infrared spectroscopy-mass spectrometry (TG-FTIR-MS) results reveal that M-UDWP significantly produces H2O and CO2 during thermal decomposition, which is one of its core fire extinguishing mechanisms. For the combustion of #RP-3 and #RP-5 aviation kerosene, commonly found in aircraft engine nacelles, the extinguishing times required by M-UDWP are 243 ms and 224 ms, respectively, with minimum extinguishing concentrations (MEC) of 25.9 g/m3 and 23.4 g/m3, respectively. The study of M-UDWP's thermal stability aids in understanding its storage stability under high-temperature conditions and its fire extinguishing mechanisms in fire zones. Moreover, the research findings suggest that M-UDWP has the potential to replace Halon 1301 in aircraft engine nacelles.

Molecular decoding a meat-like aroma generated from Laetiporus sulphureus-mediated fermentation of onion (Allium cepa L.).

The organoleptic properties of plant-based meat alternatives do not meet consumer expectations due to the lack of characteristic flavors resembling meat. To address this challenge, a fermentation system utilizing Laetiporussulphureus was developed to generate a meat-like and fatty flavor from a vegetable source, onion. By means of multiple stir bar sorptive extraction and gas chromatography-mass spectrometry-olfactometry, an unsaturated aldehyde, (E,Z)-2,4-decadienal, which imparts a tallow-like and fatty odor, and a sulfurous compound benzothiazole, with a broth-like odor were identified, which well contributed to the characteristic odor of the supernatant. (E,Z)-2,4-Decadienal as the most important odorant (odor activity value = 206) was biosynthesized by transformation of linoleic acid with L.sulphureus, as revealed by isotopic tracing experiments. For the first time in Basidiomycota, the biogenetic pathway of (E,Z)-2,4-decadienal from linoleic acid was proposed.

Rethinking the Three Rs: Growing Momentum Toward a New Gold Standard in Australian Research.

Recent years have seen increasing recognition of the scientific, economic and ethical benefits of the use of non-animal models in advancing preclinical research, giving reason to rethink the application and framework of the Three Rs. However, to benefit from the economic advantages of shifting to such alternative methods, and to realise Australia's drug development potential, legislative reform is essential. Such reform should be responsive to international regulations that encourage the use of animal-free methods, and be coupled with a corresponding re-evaluation of current Three Rs frameworks and principles. If these supportive changes, and the recommendations from the 2023 Australian Commonwealth Scientific and Industrial Research Organisation (CSIRO) Futures Non-animal models report, are implemented concurrently - with government support paramount- then a new gold standard for scientific research in Australia could be created in which the use of non-animal models and animal-free methods is the default.

Phytoconstituent Profiling and Antifungal Efficacy of Artemisia absinthium L.: Towards Sustainable Bio-Fungicide Development.

Natural alternatives to synthetic fungicides are gaining prominence as the focus sharpens on developing protective products. In this regard, the present study aimed to discern the antifungal potential of Artemisia absinthium L., a traditional medicinal plant native to Kashmir, by identifying its key phytoconstituents. Here, we present the notable antifungal activity of the leaf extract of A. absinthium against Fusarium oxysporum, Penicillium digitatum, and Alternaria solani, as observed through in vitro tests. Further refinement of the extract through chromatography isolated fraction 4 (F4), unveiling 27 compounds with no prior literature on their occurrence in A. absinthium. Additionally, in silico molecular docking analysis revealed three compounds which include Bruceine B (1), Guanidine, (phenylmethyl)- (2) and Ethyl alpha-d-glucoside (3) as potent inhibitors of multiple target key fungal enzymes such as endopolygalacturonase, chitin deacetylase and 1, 3, 8-trihydroxynaphthalene. The virtual screening unveiled compounds 1-3 within fraction 4, displaying robust binding energy ranging from -8 to -5.8 kcal/mol with multiple target enzymes. Notably, their efficacy surpassed that of the reference commercial fungicide, benodanil. This study underscores the burgeoning interest in harnessing natural alternatives for fungicidal applications, highlighting the potential of A. absinthium as a valuable resource in the quest for sustainable and effective bio-fungicides.

Chinese consumers' valuation for prepared plant-based meat products: Does environmental information matter?

Despite the growing interest in innovative nonanimal protein-prepared foods, knowledge about consumer demand for these newly prepared foods and their potential scope in the market could be improved. This study reports the results of a discrete choice experiment on consumers' (n = 1245) willingness to pay (WTP) for prepared plant-based meat (PPBM) in the context of Chinese food culture. Consumers were randomly assigned to a treated group with additional environmental information about PPBM. The estimation results of the random parameter logit model showed that when environmental information was provided, consumer preferences and WTP for frozen meatballs with mixed meat (beef-based and soy protein-based meat) and PBM (pure soy protein-based meat) significantly increased. However, their preference and WTP for food quality and safety attributes of meatballs decreased. Simultaneously, the availability of information reveals the heterogeneity of preferences. This study found that positive WTP for PPBM was limited to consumers with a low degree of food technology neophobia (FTN) and that consumers with a high degree of FTN may avoid purchasing meatballs made from PBM. In contrast, consumers with a higher time preference (i.e., impatient consumers) were likelier to pay for PPBM meatballs. PRACTICAL APPLICATION: PPBM is especially valuable in developing innovative nonanimal protein-prepared foods, and China has the potential to become the largest PPBM food market. Understanding consumers' preference for PPBM products and the impact of information provision on their WTP will assist food companies in devising suitable strategies for the development of new PPBM products. The findings of this study provide targeted market insights for the food industry to help guide the development of plant-based meat products more effectively.

Navigating Opioid Alternatives in Spine Surgery: A Comprehensive Review.

The opioid crisis has significantly impacted pain management practices in spine surgery, prompting a critical reassessment of traditional approaches. While opioids have historically been effective for post-operative pain relief, their widespread use has led to substantial public health challenges, including addiction and overdose. This review explores alternative strategies to opioids in spine surgery, emphasizing non-opioid pharmacological options [e.g., nonsteroidal anti-inflammatory drugs (NSAIDs), muscle relaxants, local anesthetics] and non-pharmacological interventions (e.g., physical therapy, cognitive-behavioral therapy). These alternatives aim to mitigate opioid-related risks while optimizing patient outcomes. Key findings highlight these approaches' efficacy, safety considerations, and practical implications. Recommendations include personalized pain management plans and multidisciplinary collaboration to enhance care delivery. Future directions suggest advancing research in innovative pain management technologies and promoting evidence-based practices to mitigate opioid dependence. Ultimately, integrating these strategies into clinical practice is essential for addressing the opioid crisis and ensuring quality care in spine surgery.

Lipid Profile of Plant-Based Milk Alternatives (PBMAs) and Cow's Milk: A Comparison.

Some consumers are replacing cow's milk with plant-based milk alternatives (PBMAs). The present study aimed to characterize the lipid profiles of cow's milk (n = 60) and PBMA types (soya, oat, rice, almond, coconut, and hazelnut; n = 10 per type). Significant differences were found in the fatty acid (FA) profiles of PBMAs and milk, particularly in FA diversity (15 FAs in PBMAs vs 54 FAs in milk) and the proportion of prime FA groups. The FA profile of coconut was dominated by saturated FAs (SFA), whereas monounsaturated FAs (MUFA) or polyunsaturated FAs (PUFA) were dominant in the remaining PBMA types. Cholesterol was not detected in any PBMA type. The FA profile of milk FAs was dominated by SFA; however, different individual SFA have varying health outcomes. Additionally, milk contains some FA groups with health-promoting properties, such as methyl-branched-chain FAs (BCFA) and conjugated linoleic acid (CLA), both of which are absent in PBMAs.

The microbial contaminants of plant-based meat analogues from the retail market.

The aim of the study was to analyse the key microbial contaminants of plant-based meat analogues (PBMA) from retail. A total of 43 samples of PBMAs (12 frozen/31 chilled) in the "ready-to-cook" category, such as hamburgers, meatballs or breaded imitation steaks were purchased in retail stores in the Czech Republic in summer (n = 21) and autumn 2022 (n = 22). The detected indicator bacteria (total viable count, lactic acid bacteria, Enterobacteriaceae, yeasts, moulds) had relatively low values in the analysed PBMA samples and only rarely reached levels of 7 log CFU/g. E. coli, STEC and coagulase-positive staphylococci were not detected by isolation from plates in any of analysed samples. Mannitol positive Bacillus spp. were isolated from almost half of the analysed samples of the PBMA. B. cereus sensu lato was isolated from 3 samples by isolation from plates, and after enrichment in 35 samples (81 %). Clostridium perfringens could not be detected by isolation from plates, nevertheless after multiplication, it was detected in 21 % of samples. Analyses of PBMA samples revealed considerable variability in microbial quality. The presence of spore-forming bacteria with the potential to cause foodborne diseases is alarming. However, to evaluate the risks, further research focused on the possibilities of growth under different conditions of culinary treatment and preservation is needed.

Mechanism and application of bacterial exopolysaccharides: An advanced approach for sustainable heavy metal abolition from soil.

The escalation of heavy metal pollutants in soils and effluents, driven by industrialization and human activities, poses significant environmental and health risks. Conventional remediation methods are often costly and ineffective, prompting a shift towards sustainable alternatives such as biological treatments. Natural biosorbents, including microbial cells and their byproducts, have emerged as promising solutions. One such approach involves leveraging exopolysaccharides (EPS), complex high-molecular-weight biopolymers synthesized by microbes under environmental stress conditions. EPS are intricate organic macromolecules comprising proteins, polysaccharides, uronic acids, humic compounds, and lipids, either located within microbial cells or secreted into their surroundings. Their anionic functional groups enable efficient electrostatic binding of cationic heavy metals, making EPS effective biosorbents for soil remediation. This review thoroughly explores the pivotal role of bacterial EPS in the removal of heavy metals, focusing on EPS biosynthesis mechanisms, the dynamics of interaction with heavy metals, and case studies that illustrate their effectiveness in practical remediation strategies. By highlighting these aspects, the review underscores the innovation and practical implications of EPS-based bioremediation technologies, demonstrating their potential to address critical environmental challenges effectively while paving the way for sustainable environmental management practices. Key findings reveal that EPS exhibit robust metal-binding capacities, facilitated by their anionic functional groups, thereby offering a promising solution for mitigating metal pollution in diverse environmental matrices.

Optimizing vegan frozen dessert: The impact of xanthan gum and oat-based milk substitute on rheological and sensory properties of frozen dessert.

This study aimed to optimize an alternative frozen dessert formulation using the response surface method (RSM). The formulation utilized oat-based milk substitute (OBMS) due to its desirable texture, sensory appeal, and nutritional benefits for vegans and lactose intolerant individuals. Xanthan gum (XG) was also incorporated to enhance the rheological properties of the dessert. With a coefficient of consistency of 192.58 Pa.s and a hysteresis field of 10,999 Pa/s, the ice cream formulation with the greatest rheological structure was discovered to be the combination of 20% oats, 0.5% xanthan gum (XG), and pasteurized at 65 °C. It also showed <10% melting in the first 10 min, confirming that it has a very stable structure. At the same pasteurization conditions and XG ratios, it was observed that rheological stability decreased with increasing oat milk addition. However, the shear thinning behavior of frozen dessert was improved by creating a more complex network structure with increasing XG concentration. The overrun values of the frozen desserts ranged from 21.55% to 34.63%, with the majority being statistically similar. The vegan frozen dessert formulation obtained with 40% oats, 0.37% XG and pasteurization at 60 °C showed a high level of sensory acceptance. This research contributes to the field of vegan food product development by providing innovative rheological and sensory alternatives to traditional frozen desserts using oats and XG.

Photo-reductive decomposition of perfluorooctane sulfonate (PFOS) and its common alternatives by UV/VUV/sulfite process: Mechanism, kinetic modeling, and water matrix effects.

The present study investigated the photo-reduction of perfluorooctane sulfonate (PFOS) and its alternatives, focusing on decomposition mechanisms, active species involvement, the influence of background water constituents, and kinetic model development. The decomposition and defluorination rates followed the order of PFOS > PFHxS > 6:2 FTSA > PFBS, with shorter chains and CH2 linkers enhancing the resistance of PFOS alternatives against the attack of hydrated electrons (eaq-). Two primary pathways were identified during the photodegradation of PFAS: (i) H/F exchange at CF bonds with the lowest bond dissociation energies (BDEs) and (ii) functional group cleavage followed by short-chain PFCAs formation, with OH playing a crucial role in transforming intermediates. Adding iodide and elevated temperatures demonstrated a synergistic effect on PFBS decomposition and defluorination, with high temperatures promoting functional group cleavage as the preferred defluorination pathway. The study examined the impact of background water constituents in different aqueous environments, from surface waters to wastewater streams and ion-exchange brine concentrates. Chloride exhibited a concentration-based dual impact on the UV/VUV/sulfite process: promotive effects at low dosages (1-10 mM) by acting as a secondary eaq- mediator, and adverse effects at high dosages (20-500 mM) due to the scavenging effect of generated chlorine radicals (Cl). High ionic strength adversely affected eaq- quantum efficiency. Additionally, bicarbonate and natural organic matter (NOM) had opposing effects on PFOS photo-reduction, primarily through eaq- scavenging and pH alteration. Kinetic modeling revealed reaction rate constants of the studied PFAS with eaq- ranging from 1.8 × 106 to 1.3 × 109 M-1 s-1, corroborating the concentration profiles of active species and highlighting the reductive nature of sulfite-mediated processes.

Industry's Perspective on Challenges Assessing the in Vivo Impact of Removing Titanium Dioxide (TiO2) from Drug Products.

The European Commission (EC) has tasked the European Medicines Agency (EMA) to provide a recommendation towards the acceptability of titanium dioxide (TiO2) in pharmaceutical products by early 2024 to inform on final decision in early 2025[1]. Unlike the already implemented ban of TiO2 in foods, removing this excipient from pharmaceutical products will likely have significant impact on the pharmaceutical industry, regulatory agencies, and patients. This commentary explores the challenges facing the pharmaceutical industry tasked with supporting the development and registration of TiO2 free (TF) drug products. Specifically, justification of formulation changes and potential impact to in vitro and in vivo performance, as well as differences in global regulatory comparative dissolution requirements to justify changing to TF drug product are discussed. Particularly, the uncertainties around how a formulation change such as removal of TiO2 from immediate release solid oral dosage forms will be viewed in Europe compared to other regions is discussed. To respond to these challenges and avoid disruption to the medicines supply chain in case in vitro data such as dissolution is either too challenging or insufficient to justify changing to TF product, pharmaceutical companies may have to decide if the level of risk is worth the effort needed to reformulate, develop, and register a new TF product.

Comparing Nutrient Profiles of Meat and Fish with Plant-Based Alternatives: Analysis of Nutrients, Ingredients, and Fortification Patterns.

Nutrient quality of plant-based meat and fish alternative (MFA) products has been reported as variable. The present objective was to compare the nutrient density of raw meat and fish with MFA products and to examine MFA ingredients and fortification patterns. Nutrient composition data for raw beef, pork, and chicken (n = 450) came from the USDA Standard Reference Legacy Reselase (SR28) nutrient composition database (n = 450). Data for plant-based meat alternatives (n = 118) came from the USDA Branded Food Products Database (BFPDB). Data for fish and seafood (n = 68) and alternatives (n = 12) came from the Danish Frida Database and Mintel (n = 503). Analyses compared macronutrient content and selected micronutrients per 100 g and percentage of US Daily Values. Nutrient density scores were based on the NRF5.3 algorithm. NRF5.3 scores were significantly lower for MFA products as compared to meat or fish. Saturated fat content was lower, but the mean MFA sodium content was 660 mg/100 g compared to 60 mg/100 g for beef. Mean protein content (17 g) was lower than for beef and pork (20 g). A search of ingredient lists found that fortification with most nutrients associated with animal source proteins (such as B vitamins, vitamin D, iodine, zinc, and omega-3 EPA and DHA) was minimal. Plant-based MFA products would benefit from nutrient standards and fortification guidelines to ensure that these products are not nutritionally inferior to the originals.

Intestinal Microbiome Profiles in Broiler Chickens Raised with Different Probiotic Strains.

The composition of the intestinal microbiota can influence the metabolism and overall functioning of avian organisms. Therefore, the objective of this study was to evaluate the effect of three different probiotics and an antibiotic on the microbiomes of 1.400 male Cobb® broiler raised for 42 days. The experiment was conducted with the following treatments: positive control diet (basal diet + antibiotic); negative control diet (basal diet without antibiotic and without probiotic); basal diet + Normal Avian Gut Flora (NAGF); basal diet + multiple colonizing strain probiotics (MCSPs); and basal diet + non-colonizing single strain probiotics (NCSSPs). The antibiotic (enramycin-antibiotic growth promoter) and probiotics were administered orally during all experiment (1 to 42 days), mixed with broiler feed. To determine the composition of the microbiota, five samples of ileal digesta were collected from 42-day-old chickens of each experimental group. The alpha and beta diversity of the ileal microbiota showed differences between the groups. MCSPs presented greater richness and uniformity compared to the positive control, negative control, and NCSSPs treatments, while the negative control exhibited greater homogeneity among samples than NCSSPs. MCSPs also showed a higher abundance of the genus Enterococcus. There were differences between the groups for low-abundance taxa (<0.5%), with NAGF showing higher levels of Delftia, Brevibacterium, and Bulleidia. In contrast, NCSSPs had a higher abundance of Ochrobactrum, Rhodoplanes, and Nitrospira. It was concluded that the treatments analyzed in this study induced modulations in the ileal microbiota of the chickens examined.

Consumer Values, Attitudes, and Behavior towards Plant-Based Alternatives.

This study investigated the impact of consumer values and attitudes to consuming plant-based alternatives (PBAs), using the value-attitude-behavior framework. The research model and hypotheses were tested using a two-step approach to structural equation modeling on 392 responses collected from PBA consumers through a research company in Korea in November 2023. The results indicated that environmental consciousness and health consciousness significantly affected attitudes toward PBAs. Also, positive attitudes toward PBAs were critical for the formation of repurchase intentions for PBAs and PBA restaurant visit behavior. Our study contributes to both academics and PBA practitioners by showing how consumer values are associated with attitudes, PBAs repurchase intentions, and PBAs restaurant visits.

Impact of Substituting Meats with Plant-Based Analogues on Health-Related Markers: A Systematic Review of Human Intervention Studies.

The growing drive towards more sustainable dietary patterns has led to an increased demand for and availability of plant-based meat analogues (PBMAs). This systematic review aims to summarize the currently available evidence from human intervention studies investigating the impact of substituting animal meat (AM) with PBMAs in adults. A total of 19 studies were included. Overall, an increase in satiety following PBMA intake was reported, albeit to different extents and not always accompanied by changes in leptin and ghrelin. PBMAs generally resulted in lower protein bioavailability and a smaller increase in plasma essential amino acids in comparison to AM. However, muscle protein synthesis and physical performance were not affected. Finally, conflicting results have been reported for other outcomes, such as pancreatic and gastrointestinal hormones, oxidative stress and inflammation, vascular function, and microbiota composition. In conclusion, we documented that the impact of substituting AM with PBMA products has been scarcely investigated. In addition, the heterogeneity found in terms of study design, population, outcomes, and findings suggests the need for additional high-quality intervention trials, particularly long-term ones, to better clarify the advantages and potential critical issues of such substitutions within sustainable healthy diets.

A qualitative evaluation of a fentanyl patch safer supply program in Vancouver, Canada.

BACKGROUND: The ongoing overdose crisis in Canada has prompted efforts to increase access to a "safer supply" of prescribed alternatives to the unregulated drug supply. While safer supply programs predominantly distribute hydromorphone tablets, the Safer Alternatives for Emergency Response (SAFER) program in Vancouver, Canada offers a range of prescribed alternatives, including fentanyl patches. However, little is known about the effectiveness of fentanyl patches as safer supply. Drawing on the perspectives and experiences of program participants, we sought to qualitatively evaluate the effectiveness of the SAFER fentanyl patch program in meeting its intended aims, including reducing risk of overdose by decreasing reliance on the unregulated drug supply. METHODS: As part of a larger mixed-methods evaluation of SAFER, semi-structured qualitative interviews were conducted with 17 fentanyl patch program participants between February 2022 and April 2023. Thematic analysis of interview data focused on program engagement, experiences, impacts, and challenges. RESULTS: The flexible program structure, including lack of need for daily dispensation, the extended missed dose protocol, and community pharmacy patch distribution fostered engagement and enhanced autonomy. Improved management of withdrawal symptoms and cravings due to steady transdermal dosing led to reduced unregulated drug use and overdose risk. Participants also experienced economic benefits and improvements in overall health and quality of life. However, skin irritation and patch adhesion issues were key barriers to program retention. CONCLUSION: Our findings demonstrate the value of including fentanyl patch safer supply in the substance use continuum of care and offer insights for innovations in delivery of this intervention.
