The surface of leaves and fruits of Peruvian cacao is home for several Hannaella yeast species, including the new species Hannaella theobromatis sp. nov.

As part of a long-term study aiming to isolate and identify yeast species that inhabit the surface of leaves and fruits of native fine-aroma cacao in the department of Amazonas, Peru, we obtained multiple isolates of Hannaella species. Yeasts of the genus Hannaella are common inhabitants of the phyllosphere of natural and crop plants. On the basis of morphological, and physiological characteristics, and sequence analysis of the D1/D2 domains of the large subunit rRNA gene (LSU) and the internal transcribed spacer region (ITS), we identified five species of Hannaella from the phyllosphere of Peruvian cacao. Four have been previously described: H. phyllophila (isolates KLG-073, KLG-091), H. pagnoccae (KLG-076), H. sinensis (KLG-121), and H. taiwanensis (KLG-021). A fifth, represented by eight isolates (KLG-034, KLG-063, KLG-074, KLG-078, KLG-79, KLG-082, KLG-084, KLG-085), is not conspecific with any previously described Hannaella species, and forms the sister clade to H. surugaensis in the phylogenetic analysis. It has 2.6-3.9% (18-27 substitutions, 2-4 deletions, and 1-3 insertions in 610-938 bp-long alignments), and 9.8-10.0% nucleotide differences (37 substitutions and 14 insertions in 511-520 bp-long alignments) in the LSU and ITS regions, respectively, to H. surugaensis type strain, CBS 9426. Herein, the new species Hannaella theobromatis sp. nov. is described and characterised. The species epithet refers to its epiphytic ecology on its host Theobroma cacao.

Effects of flavanols and procyanidins-rich cocoa consumption on metabolic syndrome: an update review (2013-2023).

Studies indicated that cocoa-based products effectively mitigate the risks associated with metabolic syndrome (MetS), however, the effect varies based on cocoa types, dosages, and study durations. This review aimed to determine the flavanol-rich cocoa consumption on MetS outcomes within the last decade (2013-2023), adhering to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Seven randomized-controlled trials (RCTs) used cocoa-based products containing 0.3-1680 mg flavanol monomers and 3.5-1270 mg procyanidins. Cocoa-based products beneficially reduced glycemic response, blood pressure and lipid profiles. However, this review highlights little evidence pinpointing the best cocoa products type and required dosage for the observed effects. Further intervention aiming to improve MetS should justify the selection and concentration of flavanols (monomers and procyanidins). A robust study design should consider registering the trials before study commencement, consider multicenter RCT trials, and adjust for potential covariates that might "masked" the outcomes.

Psychedelic mushroom-containing chocolate exposures: Case series.

INTRODUCTION: The recreational use of psilocybin or psilocin-containing products, a chemical found naturally in certain mushroom species, is on the rise across the United States. Several cases of serious clinical effects related to mushroom-containing products have recently been reported to the Food and Drug Administration (FDA). The emergence of these new products and their health consequences are not yet well understood. This case series aims to characterize exposures to mushroom-containing chocolate products, including patient characteristics, clinical effects, treatment(s), and clinical outcome severity, reported to a poison center network. MATERIAL AND METHODS: This was a retrospective case series conducted in patients exposed to mushroom-containing chocolate products across three poison centers between January 2023 to August 2024. Patients were identified via a database search of ToxSentry®. Patients were included if they were exposed to a mushroom-containing chocolate product. Patients were excluded if they ingested an unrelated product or if there was insufficient information documented within ToxSentry®. The primary endpoint was to describe clinical outcome severity after exposure to mushroom-containing chocolate products. RESULTS: A query of ToxSentry® identified 164 cases; 36 cases met study criteria. The median age of patients in this case series was 17 years old. For most patients (23, 64 %), the reason for the exposure was intentional, with 20 reporting intentional abuse or misuse of the product. Common clinical effects reported included mental status changes (26, 76 %), paranoia/hallucinations (10, 28 %), dysrhythmias (7, 19 %) and gastrointestinal discomfort (6, 17 %). There was one report of seizure. Most clinical effects lasted between 3 and 24 h after ingestion (29, 81 %). Intravenous fluids (18, 50 %) and benzodiazepines (7, 19 %) were the most common treatments given. No fatalities were reported. DISCUSSION: While most patients in this series experienced minor clinical effects, some developed serious effects after ingestion of a mushroom-containing chocolate product. Findings from this study further characterize the limited patient demographics, clinical effects, and outcomes published thus far. Further characterization in a larger cohort of patients could expand on our initial findings and is needed to better identify factors that may influence clinical outcomes.

Imagine chocolate: The craving experience questionnaire in the food domain.

Measurement of food craving has gained relevance in the current obesity epidemic. The Craving Experience Questionnaire (CEQ) considers not only craving intensity but also cognitive intrusiveness and imagery vividness as separate craving factors and could thus refine food craving assessment. It is available in two versions with ten items each. The CEQ-F assesses craving frequency across specific time periods and the CEQ-S time-point specific craving strength. Across three independent studies, N = 533 participants completed the German chocolate CEQ-F referenced at the past year to operationalise trait-like craving. Among them, N = 402 also completed the German chocolate CEQ-S referenced at the current moment to operationalise state-like craving. Four-week test-retest reliability was measured. For external validity, we assessed self-reported chocolate consumption, body-mass-index, trait approach motivation, general imagery vividness, and the most widely used food craving questionnaire, namely the Food Cravings Questionnaires in a trait (FCQ-T-r) and state version (FCQ-S), as well as behavioural approach bias (reaction time-based measurement). The three-factor structure was replicated with excellent internal consistency for both CEQ-F and CEQ-S. Test-retest reliability was moderate for both CEQ versions. CEQ-F scores were related to higher levels of chocolate consumption, approach motivation, and FCQ-T-r scores, but not to body-mass-index, imagery vividness, or approach bias. CEQ-S scores were associated with FCQ-S scores and partly with approach bias, but not with approach motivation and imagery vividness. The current results support the factor structure, validity and reliability of the German chocolate CEQ-S and CEQ-F with questions remaining regarding the ability of the CEQ-S to measure state craving. Thus, CEQ-F and CEQ-S usefully contribute to food craving assessment.

Counts of mesophilic aerobic, mesophilic anaerobic, thermophilic aerobic sporeforming bacteria and persistence of Bacillus cereus spores throughout cocoa powder processing chain.

Sporeforming bacteria are a concern in some food raw materials, such as cocoa powder. Samples (n = 618) were collected on two farms and at several stages during cocoa powder manufacture in three commercial processing lines to determine the impact of each stage on bacterial spore populations. Mesophilic aerobic, mesophilic anaerobic, thermophilic aerobic, and Bacillus cereus spore populations were enumerated in all the samples. Genetic diversity in B. cereus strains (n = 110) isolated from the samples was examined by M13 sequence-based PCR typing, partial sequencing of the panC gene, and the presence/absence of ces and cspA genes. The counts of different groups of sporeforming bacteria varied amongst farms and processing lines. For example, the counts of mesophilic aerobic spore-forming (MAS) populations of cocoa bean fermentation were lower than 1 log spore/g in Farm 1 but higher than 4 log spore/g in Farm 2. B. cereus isolated from cocoa powder was also recovered from cocoa beans, nibs, and samples after roasting, refining, and pressing, which indicated that B. cereus spores persist throughout cocoa processing. Phylogenetic group IV was the most frequent (73%), along with processing. Strains from phylogenetic group III (14 %) did not show the ces gene's presence.

Optimization of N Fertilizer and Synergistic Intercropping to Enhance the Productivity Advantage of Faba Bean and Effective Control of Chocolate Spot Epidemics.

Intercropping of wheat/faba bean is a common practice within the legume-cereal family. However, the benefits of nitrogen (N) fertilizer-optimized synergistic intercropping in improving faba bean productivity while controlling the prevalence of chocolate spot disease have not been established. This study conducted continuous field experiments spanning two planting seasons to investigate two key findings: (i) Optimizing N fertilizer application can enhance the productivity of intercropped faba bean. (ii) The percentage severity index (PSI) during the period of maximum prevalence rate (Rmax) of faba bean chocolate spot disease poses a substantial challenge to faba bean yield. The results indicated that the land equivalent ratio and transgressive overyielding index for each intercropping treatment increased with higher N fertilizer application, exceeding a value of 1, and the land saving proportion also exceeded 0. Intercropping primarily enhances productivity, as measured by the harvest index (HI), by amplifying the complementary effect rather than the selection effect, thus improving the net benefit of intercropping. The HI of single and intercropped faba bean increased with the N1 and N2 treatments in both planting seasons. However, the HI of single and intercropped faba bean at the N3 level decreased significantly, ranging from 17.85 to 29.62%. Furthermore, a notable negative correlation was established between the PSI during critical epidemic (initial epidemic, maximum epidemic rate, and late epidemic) periods and observed and expected faba bean yields. As the PSI increased, faba bean yields decreased, and the PSI of intercropping at different periods was lower than that observed in the single cropping. Additionally, intercropping with the optimized N fertilizer treatment (N2 treatment) exhibited an enhanced relative control effect on chocolate spot disease in faba bean, ranging from 35.21 to 52.36%. This finding confirmed the productivity advantage of intercropping faba bean. In conclusion, this study suggested that optimizing N fertilizer application can enhance the productivity of intercropped faba bean. Wheat/faba bean intercropping effectively controlled the PSI during the period of Rmax, which would otherwise threaten faba bean yield. Consequently, this practice ensured sustained advantages of wheat/faba bean intercropping.

Immune Dysregulation in Endometriomas: Implications for Inflammation.

The most common manifestation of endometriosis, a condition characterized by the presence of endometrial-like tissue outside of the uterus, is the endometrioma, a cystic ovarian lesion. It is a commonly occurring condition associated with chronic pelvic pain exacerbated prior to and during menstruation, as well as infertility. The exact pathomechanisms of the endometrioma are still not fully understood. Emerging evidence suggests a pivotal role of immune dysregulation in the pathogenesis of endometriomas, primarily influencing both local and systemic inflammatory processes. Among the factors implicated in the creation of the inflammatory milieu associated with endometriomas, alterations in both serum and local levels of several cytokines stand out, including IL-6, IL-8, and IL-1ß, along with abnormalities in the innate immune system. While numerous signaling pathways have been suggested to play a role in the inflammatory process linked to endometriomas, only NF-κB has been conclusively demonstrated to be involved. Additionally, increased oxidative stress, both resulting from and contributing to endometriomas, has been identified as a primary driver of both systemic and local inflammation associated with the condition. This article reviews the current understanding of immune dysfunctions in the endometrioma and their implications for inflammation.

Chemical Composition of Fat Bloom on Chocolate Products Determined by Combining NMR and HPLC-MS.

To reduce unwanted fat bloom in the manufacturing and storage of chocolates, detailed knowledge of the chemical composition and molecular mobility of the oils and fats contained is required. Although the formation of fat bloom on chocolate products has been studied for many decades with regard to its prevention and reduction, questions on the molecular level still remain to be answered. Chocolate products with nut-based fillings are especially prone to undesirable fat bloom. The chemical composition of fat bloom is thought to be dominated by the triacylglycerides of the chocolate matrix, which migrate to the chocolate's surface and recrystallize there. Migration of oils from the fillings into the chocolate as driving force for fat bloom formation is an additional factor in the discussion. In this work, the migration was studied and confirmed by MRI, while the chemical composition of the fat bloom was measured by NMR spectroscopy and HPLC-MS, revealing the most important triacylglycerides in the fat bloom. The combination of HPLC-MS with NMR spectroscopy at 800 MHz allows for detailed chemical structure determination. A rapid routine was developed combining the two modalities, which was then applied to investigate the aging, the impact of chocolate composition, and the influence of hazelnut fillings processing parameters, such as the degree of roasting and grinding of the nuts or the mixing time, on fat bloom formation.

Multistakeholder Initiatives and Sustainability? A Governance Analysis using the German Initiative on Sustainable Cocoa (GISCO) as a Case Study.

This paper examines the Multistakeholder initiative (MSI) "German Initiative on Sustainable Cocoa (GISCO)". MSIs represent arenas in which heterogeneous actors from governments, businesses and civil society come together to achieve sustainability goals that they cannot achieve otherwise. The self-defined goals of GISCO are first, to improve the living conditions of cocoa farmers and their families; second, to conserve and protect natural resources and biodiversity; and third, to increase the share of sustainably produced cocoa. Although all stakeholder groups share these goals, they have different agendas and conflicting interests. Despite numerous case studies, no theoretical basis has been established on the functioning and success of negotiations in MSIs. Therefore, the question arises as to how the governance of an MSI can be captured empirically to explain (un)achieved outcomes of the collaboration. The contribution of this paper is the development of a theoretical framework and its application to the case study. Minutes of 84 meetings and 18 qualitative expert interviews were analyzed by social network analysis and qualitative content analysis using MaxQDA to identify (a) influential actors, (b) collaboration structures and (c) processes as well as (d) topics discussed to explain (not) achieved outcomes regarding the self-defined goals. The results provide detailed insight into the governance of an MSI. The MSI helps members to extend their individual networks and to learn from each other, but quickly reaches its limits in achieving the self-imposed common goals. One reason for this is the lack of representation of actors from the Global South, despite addressing environmental and living conditions there in two out of the three GISCO goals. Furthermore, it is shown that the structures and processes of decision-making within the MSI are designed in such a way that a lack of hierarchical directives, sanctions and other decision-making mechanisms makes negotiation-based compromises difficult. Consequently, the power of each stakeholder group to use their veto right to delay or prevent the changes required to achieve common goals cannot be overcome.

Integrating new variables into a framework to support cacao denomination of origin: a case study in Southwest Colombia.

BACKGROUND: Cocoa quality plays a pivotal role in establishing denominations of origin, with genotypes, geography, climate and soil conditions being key variables. However, these factors have not been comprehensively explored in defining cacao denominations of origin. The present study addresses this gap by laying the foundation for cacao denomination of origin, focusing on the Buenaventura region on Colombia's Pacific coast. Our goal is to provide a holistic understanding of the elements underpinning cacao denomination of origin, emphasizing Buenaventura's unique cocoa quality and geographical significance. RESULTS: Through the Buenaventura case, we propose a robust framework applicable to other cacao-producing regions, elevating the recognition and value of cacao denomination of origin. Our framework encompasses geography, agronomy, genetics, microbial diversity, pests and diseases and cocoa quality. In a pioneering move, we propose a cacao denomination of origin in Colombia, specifically examining Bajo Calima, Sabaletas and Cisneros within Buenaventura region. Buenaventura stands out for its cocoa quality, characterized by fruity flavors attributed to the rich biodiversity of the lowland rainforest. CONCLUSION: Our analysis indicates specific geographical indicators for each of the study zones, with Buenaventura identified as a region with natural characteristics to produce fine flavour cocoa products. Each zone exhibited a high differentiation and diversity of cacao cultivars. Buenaventura has the potential to be designated as a future denomination of origin for cacao from the Pacific region of Colombia, characterized by its unique fruity-aroma chocolates. Our framework is adaptable to other cacao-producing regions, facilitating the establishment of denominations of origin within the cocoa industry and agriculture. © 2023 The Authors.

Investigating the physicochemical properties, sensory profile and consumer acceptability of beetroot dark chocolate.

BACKGROUND: The incorporation of functional food ingredients in chocolate that seek to eliminate, if not completely, most of the added sugar content, as well as the use of alternative chocolate production techniques, have gained popularity in recent years. This study aimed to incorporate red beetroot powder into dark chocolate and investigate the effect of red beetroot powder concentration and processing time in a melanger on the physicochemical properties, sensory profile and consumer acceptability of beetroot dark chocolate. RESULTS: The addition of red beetroot powder increased the moisture content, particle size distribution and hardness of the chocolates, while the opposite was true for processing time with no effect on the colour. Except for taste, which had an average score of 3.2 ± 1.8 on the 7-point hedonic scale, consumers scored all the other sensory attributes of the chocolates above 4.0. Among the chocolates with red beetroot powder, samples with a 15% red beetroot powder addition had a high average overall acceptability score of >5, while the 30% sample scored <4. CONCLUSION: Red beetroot powder can be used to replace sugar in dark chocolate without affecting its physicochemical properties, sensory profile or consumer acceptability. However, the target market should be considered when determining the level of red beetroot powder incorporation in terms of chocolate taste. This research has the potential to improve the overall health-promoting properties of dark chocolate by eliminating added sugar (partially or completely). It would also help to diversify beetroot utilization, allow small-scale processors to venture into chocolate production and expand the small-scale chocolate value chain. © 2024 Society of Chemical Industry.

The severity and yield effects of the chocolate spot disease in faba bean affected by intercropping and nitrogen input.

BACKGROUND: The aim is to study the disease suppression efficiency, yield loss rate, and yield benefits of intercropped faba bean against chocolate spot under nitrogen (N) input, to clarify the effectiveness of intercropping faba beans in controlling chocolate spot and its contribution to yield increase. RESULTS: Four N input levels and disease suppression treatments were discovered when faba bean-wheat intercropped was used. Adding N enhanced the chocolate spot's area under disease progression curve (AUDPC) by 27.1-69.9%. In contrast to monoculture, intercropping reduced the AUDPC of the chocolate spot by 32.4-51.0% (P < 0.05). Interestingly, the relative control efficacy (RCE) of intercropping at the EShan site was better. With disease suppression or non-suppression, N input increased grain yield loss and its components in faba bean. The total yield advantage effect (TE) and disease-suppression effect (DSE) of faba bean intercropped at the two experimental sites were significantly increased under N input (N1 and N2 level). The proportion of recovery yield due to intercropping suppressed disease (DSE/TE ratio) in EShan (52.1%) was higher than that in Xundian (40.9%), and the DSE of intercropping played an indispensable role in the two sites. Regression analysis of AUDPC and grain yield loss amount showed that one unit increase in chocolate spot AUDPC could cause a grain yield loss of 0.38-0.86 kg ha-1 . The partial land equivalent ratio (pLER) of intercropping faba beans at the EShan site was > 0.33. CONCLUSION: In conclusion, intercropped faba bean with N treatment (45-90 kg ha-1 ) was the best choice for maximizing the intercropping disease control effect. © 2023 Society of Chemical Industry.

Assessing the cadmium content of cacao crops in Arauca, Colombia.

The district of Arauca is the second-largest producer of cacao in Colombia. However, despite its quality, it faces issues for export due to levels of cadmium (Cd) higher than the regulatory thresholds. A central question is how it may impact agricultural performance in the presence of Cd in cacao and chocolates. This study quantified Cd in cacao plantations from Arauca. Thus, 180 farms were assessed in the municipalities of Arauquita, Fortul, Saravena, and Tame. Five sample types (soil, irrigation channel sediment, soil litter, cacao seeds, and chocolates) were assessed for Cd. As a technological innovation, the new MXRF technology was used for Cd in chocolates. The sequence of Cd content was soil litter > chocolate > soils > cacao seeds > irrigation-channel sediment. A gradient north-south of Cd content in soil was observed, where highest content was found in farms near the Arauca River, and lower farther away. In irrigation channel sediment, Cd levels averaged 0.07 mg kg-1. The Cd content in cacao seeds was 0.78 mg kg-1 on average. Cd content in chocolates was above the threshold (1.10 mg kg-1 on average, including several cacao mass percentages). These artisanal chocolate bars produced by single farms were near the limit of Cd set by the European Union (up to 0.8 mg kg-1). Therefore, mixing beans from different farms could reduce their Cd content. The present study underscores the complexity of Cd distribution, emphasizing the importance of integrating soil, crop, and landscape features in managing and mitigating Cd levels in cacao.

What every dentist needs to know about chocolate.

Chocolate is one of the most popular treats in the world. Debate over the potential benefits of its consumption has made chocolate a widely researched health topic. This article reviews the general health benefits of chocolate consumption, focusing on its involvement with the oral microbiota, caries development, and biofilm control, and discusses the potential negative consequences of excess chocolate consumption.

Dark chocolate: delivery medium for probiotic Bifidobacterium breve NCIM 5671.

Bifidobacteria are widely acclaimed probiotic bacteria, however, the fragile nature of the bacteria has rendered its delivery through food products a challenge. The aim of the present study was to develop probiotic dark chocolate by incorporating Bifidobacterium breve NCIM5671. The probiotic chocolate was prepared by adding B. breve to dark chocolate at the final tempering stage. The chocolate was evaluated for the viability of B. breve upon preparation and during storage period of 90 days. The effect of addition of B. breve on physiological parameters of chocolate such as color, texture, rheology, melting profile, and sensory profile was also determined. The probiotic chocolate developed retained viability of B. breve (9 log CFU/g) for a period of 90 days. No significant differences were observed in physiological parameters of probiotic chocolate compared to control chocolate. Overall the probiotic dark chocolate was found to be a suitable matrix for delivery of B. breve NCIM5671.

Carnauba wax and adipic acid oleogels as an innovative strategy for cocoa butter alternatives in chocolate spreads.

The aim of this study was to replace cocoa butter substitute (CBS) with structured sunflower oil in chocolate spread partially. Two types of oleogel, 6% carnauba wax (CWO) and 2% carnauba wax with 4% adipic acid (AD-CWO) were substituted (at 20%, 50%, and 70%), and chocolate spread characteristics were evaluated. Various properties of chocolate spread samples were investigated as peroxide value, firmness, oil binding capacity, moisture content, molecular interactions, and molecular conformation of fat crystals. The increasement of CBS substitution by oleogel in samples significantly reduced firmness. The samples with 20% replacement formulated by CWO and AD-CWO had the highest oil binding capacity, 97.48 ± 0.21% and 97.73 ± 0.02, respectively. Moreover, oxidative stability analysis showed a positive correlation with an increasing replacement level over 90 days of storage. Based on FT-IR analysis, the new intermolecular hydrogen bond formation in the oleogel-based spreads network has been confirmed. CBS replacement with oleogels revealed the presence of stable ß´ polymorphs with low intensity. In conclusion, the carnauba-based oleogels have significant potential to substitute CBS in chocolate spread partially.

Discriminating three lab scale dark chocolate bars from fine Cameroon cocoa hybrids using sensorial evaluation and organic acid content.

Previous studies have shown a correlation between chocolate sensory profile and certain (bio)chemical components. The aim of this study was to examine the sensorial profile and organic acid content of three lab scale chocolate brands produced from different cocoa genotypes. The sensorial evaluation was examined by a team of 12 panelists and evaluation of aroma volatiles was done by means of HS-SPME-GC-MS. On the other hand, organic acids were assessed using a high-performance ion chromatography coupled with an electrochemical detector (HPIC-ED). Results showed a variability in sensorial profile: SCA12×ICS40 chocolate (vanilla/sweet, spicy, and floral), ICS40 × SCA12 chocolate (fruity, bitter, and dry) and SNK16 × T60/887 chocolate (chocolate, honey-like, woody, sweet). Moreover, some aroma volatiles like (2-methyl, 3-methyl, iso) butanal (ICS), terpenes (SCA), and ketones (acetophenone and 2-nonanone) (SNK) allowed to discriminate dark chocolate sample according to their raw cocoa genetic group. Besides, the organic acid content differed from one chocolate brand to another, and it was obtained a high content of oxalic acid and a low lactic acid content which are good indicators of chocolate quality. Results of the current study highly recommend knowing the variety of cocoa beans with high content of some volatiles and high oxalic and low acetic acid and lactic contents to produce high aromatic (special flavor) chocolates.

Randomized Trial of Chocolate Touch Compared With Lutonix Drug-Coated Balloon in Femoropopliteal Lesions (Chocolate Touch Study).

BACKGROUND: First-generation drug-coated balloons (DCBs) have significantly reduced the rate of restenosis compared with balloon angioplasty alone; however, high rates of bailout stenting and dissections persist. The Chocolate Touch DCB is a nitinol constrained balloon designed to reduce acute vessel trauma and inhibit neointima formation and restenosis. METHODS: Patients with claudication or ischemic rest pain (Rutherford class 2-4) and superficial femoral or popliteal disease (≥70% stenosis) were randomized 1:1 to Chocolate Touch or Lutonix DCB at 34 sites in the United States, Europe, and New Zealand. The primary efficacy end point was DCB success, defined as primary patency at 12 months (peak systolic velocity ratio <2.4 by duplex ultrasound without clinically driven target lesion revascularization in the absence of clinically driven bailout stenting). The primary safety end point was freedom from major adverse events at 12 months, a composite of target limb-related death, major amputation, or reintervention. Both primary end points were tested for noninferiority, and if met, sequential superiority testing for efficacy followed by safety was prespecified. An independent clinical events committee, and angiographic and duplex ultrasound core laboratories blinded to treatment allocation reviewed all end points. RESULTS: A total of 313 patients were randomized to Chocolate Touch (n=152) versus Lutonix DCB (n=161). Follow-up at 1 year was available in 94% of patients. The mean age was 69.4±9.5 years, the average lesion length was 78.1±46.9 mm, and 46.2% had moderate-to-severe calcification. The primary efficacy rates of DCB success at 12 months was 78.8% (108/137) with Chocolate Touch and 67.7% (88/130) with Lutonix DCB (difference, 11.1% [95% CI, 0.6-21.7]), meeting noninferiority (Pnoninferiority<0.0001) and sequential superiority (Psuperiority=0.04). The primary safety event rate was 88.9% (128/144) with Chocolate Touch and 84.6% (126/149) with Lutonix DCB (Pnoninferiority<0.001; Psuperiority=0.27). CONCLUSIONS: In this prospective, multicenter, randomized trial, the second-generation Chocolate Touch DCB met both noninferiority end points for efficacy and safety and was more effective than Lutonix DCB at 12 months for the treatment of femoropopliteal disease.

Role of CB2 cannabinoid receptor in the development of food addiction in male mice.

The endocannabinoid system plays an important role in multiple behavioral responses due to its wide distribution in the central nervous system. The cannabinoid CB1 receptor was associated to the loss of behavioral control over food intake occurring during food addiction. The cannabinoid CB2 receptor (CB2R) is expressed in brain areas canonically associated with addictive-like behavior and was linked to drug-addictive properties. In this study, we evaluated for the first time the specific role of the CB2R in food addiction by using a well-validated operant mouse model of long-term training to obtain highly palatable food. We have compared in this model the behavioral responses of wild-type mice, mutant mice constitutively lacking CB2R, and transgenic mice overexpressing CB2R. The lack of CB2R constitutes a protective factor for the development of food addiction and the impulsive and depressive-like behavior associated. In contrast, the overexpression of CB2R induces a vulnerable phenotype toward food addiction after long-term exposure to highly palatable chocolate pellets. Relevant transcriptomic changes were associated to resilience and vulnerability to food addiction depending on the genotype, which provides a mechanistic explanation for these behavioral changes. Therefore, CB2R may constitute a potential therapeutic target for the loss of eating control and the comorbid emotional effects associated to food addiction.

Cocoa polyphenols and milk proteins: covalent and non-covalent interactions, chocolate process and effects on potential polyphenol bioaccesibility.

In this study, we discussed covalent and non-covalent reactions between cocoa polyphenols and proteins (milk and cocoa) and the possible effects of these reactions on their bioaccessibility, considering environmental and processing conditions. Better insight into these interactions is crucial for understanding the biological effects of polyphenols, developing nutritional strategies, and improving food processing and storage. Protein-polyphenol reactions affect the properties of the final product and can lead to the formation of various precursors at various stages in the manufacturing process, such as fermentation, roasting, alkalization, and conching. Due to the complex composition of the chocolate and the various technological processes, comprehensive food profiling strategies should be applied to analyze protein-polyphenol covalent reactions covering a wide range of potential reaction products. This will help to identify potential effects on the bioaccessibility of bioactive compounds such as low-molecular-weight peptides and polyphenols. To achieve this, databases of potential reaction products and their binding sites can be generated, and the effects of various process conditions on related parameters can be investigated. This would then allow to a deeper insight into mechanisms behind protein-polyphenol interactions in chocolate, and develop strategies to optimize chocolate production for improved nutritional and sensory properties.
