This study aimed to evaluate the possible mediating role of psychological flexibility in the association between fear of COVID-19, affective symptoms and well-being. 403 subjects were recruited; fear of COVID-19, psychological flexibility, affective symptoms and well-being were assessed via self-report measures. Correlation and mediation analyses were run. Psychological flexibility was found to play a mediating role in the association between fear of COVID-19 and more severe affective symptoms (adjusted R-squared = 52%, p < 0.001), and between fear of COVID-19 and poor well-being (adjusted R-squared = 41%, p < 0.001). Psychological flexibility may mitigate the negative impacts of fear of COVID-19 on affective symptoms and well-being Psychological flexibility could be the potential therapeutic target in clinical interventions aimed at reducing the adverse effects of fear of COVID-19 on mental health.

Case conceptualization is a widely used tool to describe and organize patient information and plan interventions in psychotherapy. Life themes and semi-adaptive plans: Implications of biased beliefs, elicitation, and treatment (LIBET) is a new method for case conceptualization that validates the diathesis-stress model and incorporates elements from the most important theories in the CBT field. LIBET also includes process-based components as maintaining factors of psychological distress, and it is not anchored to a specific kind of psychotherapeutic approach. The LIBET-Questionnaire (LIBET-Q) is a structured interview which helps clinicians achieve a LIBET case conceptualization, co-constructed with patients. The aim of the present study was to validate the process-based section of the LIBET-Q by analyzing its factorial structure, internal consistency, convergent validity, and clinical relevance. A sample of 396 outpatients was recruited to validate the LIBET-Q, which was administered along with interviews and self-report questionnaires to investigate the presence of diagnoses, anxiety, and depression levels and global functioning and wellbeing. Results from both exploratory and confirmatory factor analyses showed a four-factor structure, with adequate consistency and good convergent validity. Process-based elements investigated with the LIBET-Q resulted in identifying different clinical populations. With satisfactory psychometric properties, the LIBET-Q turned out to be a suitable support for case conceptualization and treatment formulation. The independence of the LIBET method from a specific intervention can improve its sharing between clinicians by offering a common frame in which the rationale of every specific technique can be explained.

(1) Background: Computed tomography (CT) plays a paramount role in the characterization and follow-up of COVID-19. Several score systems have been implemented to properly assess the lung parenchyma involved in patients suffering from SARS-CoV-2 infection, such as the visual quantitative assessment score (VQAS) and software-based quantitative assessment score (SBQAS) to help in managing patients with SARS-CoV-2 infection. This study aims to investigate and compare the diagnostic accuracy of the VQAS and SBQAS with two different types of software based on artificial intelligence (AI) in patients affected by SARS-CoV-2. (2) Methods: This is a retrospective study; a total of 90 patients were enrolled with the following criteria: patients' age more than 18 years old, positive test for COVID-19 and unenhanced chest CT scan obtained between March and June 2021. The VQAS was independently assessed, and the SBQAS was performed with two different artificial intelligence-driven software programs (Icolung and CT-COPD). The Intraclass Correlation Coefficient (ICC) statistical index and Bland–Altman Plot were employed. (3) Results: The agreement scores between radiologists (R1 and R2) for the VQAS of the lung parenchyma involved in the CT images were good (ICC = 0.871). The agreement score between the two software types for the SBQAS was moderate (ICC = 0.584). The accordance between Icolung and the median of the visual evaluations (Median R1–R2) was good (ICC = 0.885). The correspondence between CT-COPD and the median of the VQAS (Median R1–R2) was moderate (ICC = 0.622). (4) Conclusions: This study showed moderate and good agreement upon the VQAS and the SBQAS; enhancing this approach as a valuable tool to manage COVID-19 patients and the combination of AI tools with physician expertise can lead to the most accurate diagnosis and treatment plans for patients.

Although a probable association between metacognitive beliefs (also termed 'metacognitions') and emotion dysregulation has been suggested in the literature, the evidence is still sparse and inconclusive. The current study aims to present a comprehensive evaluation of the literature examining the association between metacognitive beliefs and emotion dysregulation. In accordance with Preferred Reporting Items for Systematic Reviews and Meta‐Analyses (PRISMA) criteria, a search was conducted on PubMed and Ebsco. A manual search of reference lists was also run. Search terms were 'metacognitions/metacognitive beliefs/positive metacognitive beliefs/negative metacognitive beliefs/cognitive self‐consciousness/beliefs about the need to control thoughts/cognitive confidence/negative beliefs about thoughts concerning uncontrollability and danger/AND difficulties emotion regulation/emotion dysregulation'. A total of 19 studies met the inclusion criteria. In both non‐clinical and clinical populations, a higher endorsement of dysfunctional metacognitive beliefs was found to be associated with emotion dysregulation and vice versa. A higher endorsement of metacognitive beliefs may be associated, either directly or via maladaptive forms of mental control (e.g., worry, rumination and suppression) to emotion dysregulation. Metacognitive beliefs could be the potential therapeutic target in clinical interventions aimed at reducing emotion regulation difficulties. [ABSTRACT FROM AUTHOR]

Introduction: Using the Self‐Regulatory Executive Function model as a basis, this study explored whether, in patients with eating disorders (EDs), metacognitions and repetitive negative thinking are associated with higher levels of perfectionisms. Methods: One hundred twenty‐three outpatients with EDs were recruited. Perfectionism, metacognitive beliefs, worry, rumination, anger rumination, affective and eating symptoms were assessed. Correlation and hierarchal regression analyses were run. Results: Higher endorsement of positive beliefs about worry was associated with higher levels of 'personal standards perfectionism'. Higher endorsement of positive beliefs about worry, need to control thoughts, worry and rumination was associated with higher levels of 'concern over mistakes perfectionism'. Conclusions: Among patients with EDs, perfectionism appears to be associated with the endorsement of dysfunctional metacognitive beliefs, worry and rumination. Dysfunctional metacognitive beliefs and repetitive negative thinking could be suitable therapeutic targets to reduce the levels of perfectionism among patients with EDs. [ABSTRACT FROM AUTHOR]

Summary: Phenolics bound to dietary fibres (DF‐PCs) represent a valuable source of antioxidants that are often wasted. DF‐PCs can be obtained as residues from conventional extraction processes of PCs derived from agro‐industrial by‐products. This study aimed to characterise DF‐PCs generated after the PC extraction process from the avocado peel (AP), mango peel (MP) and husk mango seed (testa) (MT), with a focus on solid residue or concentrated fibre (APFT: avocado peel fibre; MPFT: mango peel fibre; MTFT: mango testa fibre). The by‐products were evaluated under both non‐defatted and defatted conditions before simulating the PC extraction process. PCs were quantified (TPC) and identified (HPLC‐IDA‐EPI‐MS). Their antioxidant activity (AA) was determined (ABTS+, DPPH* and FRAP). Among the evaluated fibres, non‐defatted AP and defatted MP and MT exhibited the highest TPC content (22.64 ± 0.3, 37.31 ± 1.78 and 6.07 ± 0.08 mg GAE/g), respectively. Using the DPPH* assay, all fibre concentrates showed lower AA compared to the by‐products. Using FRAP assay, defatting gave the largest activity for mango samples. HPLC‐IDA‐EPI‐MS analysis of PC profiles resulted in the presence of 62 PC compounds in the fibre concentrates. These DF‐PCs, with a significant content of PCs, may be relevant as functional ingredients for food production. [ABSTRACT FROM AUTHOR]

Introduction: The COVID‐19 Anxiety Syndrome Scale (C‐19ASS) is a reliable scale assessing dysfunctional coping strategies activated in response to COVID‐19 fear and threat. The present study aimed to provide a validation of the Arabic version of the C‐19ASS and to explore the association between the C‐19ASS and psychological symptoms syndrome. Method: In Study 1, a community sample of 404 participants completed the Arabic version of the C‐19ASS and results were subjected to an exploratory factor analysis. In Study 2, a community sample of 903 participants completed the Arabic version of the C‐19ASS and a series of measures assessing depressed mood and anhedonia, generalized anxiety and health anxiety. Internal consistency, construct validity and incremental validity were assessed. Associations between C‐19ASS and psychological symptoms were assessed. Results: Factor analysis identified a two‐factor solution (i.e., C‐19ASS‐Perseveration and C‐19ASS‐Avoidance), and confirmatory factor analysis suggested a two‐factor model best fits the data. The Arabic version of the C‐19ASS showed good internal consistency, good construct and incremental validity. COVID‐19 anxiety syndrome was associated with more severe anxiety symptoms, depressive symptoms and health anxiety. Females had higher levels of COVID‐19 anxiety syndrome than males. Participants diagnosed with COVID‐19, and those who had experienced loss as a consequence of COVID‐19, had higher levels of COVID‐19 anxiety syndrome (Perseveration). Conclusions: The Arabic version of the C‐19ASS appears to be a reliable and valid measure of the COVID‐19 anxiety syndrome. The COVID‐19 anxiety syndrome could be a suitable therapeutic target to improve psychological recovery during the COVID‐19 pandemic among Arabs. [ABSTRACT FROM AUTHOR]

Background: Using the Self-Regulatory Executive Function model as a basis, this study explored whether, in patients with eating disorders (EDs), metacognitions and repetitive negative thinking are associated with higher levels of emotion dysregulation. Methods: 104 outpatients with eating disorders and 104 controls from the general population were recruited. Emotion dysregulation, metacognitions, rumination, worry, anxiety, and depression were assessed. T-tests, Mann–Whitney tests, correlation and hierarchal regression analyses were run. Results: Patients with EDs, compared to controls, reported significantly higher levels of emotion dysregulation, positive beliefs worry, negative beliefs about thoughts concerning uncontrollability and danger, beliefs about the need to control thoughts, rumination, and worry. Beliefs about the need to control thoughts and worry significantly predicted emotion dysregulation. Conclusions: Among patients with EDs emotion dysregulation appears to be associated with the endorsement of beliefs about the need to control thoughts and worry. Beliefs about the need to control thoughts and worry could be a suitable therapeutic target to reduce emotion dysregulation among patients with EDs. [ABSTRACT FROM AUTHOR]

In this work, the chemical composition and the antioxidant evaluation of the inflorescences from 12 Cannabis sativa L. monoecious cultivars (Carmagnola Lemon CL, Ferimon F, Gran Sasso Kush GSK, Antal A, Carmagnola C, Kompolti K, Futura 75 F75, Villanova V, Tiborzallasi T, Finola FL, Kc Virtus KV and Pineapple P) cultivated at the same condition, were investigated. GC-MS analysis was carried out to evaluate the volatile fraction, while HPLC-MS/MS was used for cannabinoids and polyphenolic compounds. The evaluation of antioxidant activity was carried out using ABTS*+, Trolox equivalence antioxidant capacity (TEAC), ferric reducing antioxidant property (FRAP) and 2,2-diphenyl-1-picrylhydrazyl (DPPH*) assays in vitro. The obtained data, demonstrated that each cultivar has a characteristic chemical profile, with highest antioxidant capacity for CL, F75, GSK and F. Based on the in vitro antioxidant activity the plant extracts can be considered as promising candidates for different applications in food field. [ABSTRACT FROM AUTHOR]

Human respiratory syncytial virus (RSV) is a main cause of medical referrals and hospitalizations in all infants, particularly among newborns. Nevertheless, relatively limited evidence on chest tomography (CT) findings has been collected. According to the PRISMA statement, Pubmed, Embase, and medRxiv were searched for eligible observational studies published up to 31 December 2022. Cases were categorized in children and adolescents (age < 18 years), adults and elderly (age ≥ 18 years), and immunocompromised patients, and then pooled in a random-effects model. Heterogeneity was assessed using the I2 statistics, while reporting bias was assessed by means of funnel plots and regression analysis. A total of 10 studies (217 RSV cases) were retrieved (children, 37.3%; immunocompromised, 41.0%; adults, 21.7%). The most common features were signs of organizing pneumonia (33.65%, 95% confidence interval [95% CI] 22.39–47.27), followed by septal thickening (33.19%, 95% CI 21.76–47.03), ground glass opacities (GGOs; 28.03%, 95% CI 14.69–46.82), and tree-in-bud (TIB, 27.44%, 95% CI 15.04–44.68). Interestingly, up to 16.23% (95% CI 8.17–29.69) showed normal findings, while the large majority (76.06%, 95% CI 64.81–84.56) were characterized by bilateral involvement. Studies were highly heterogeneous without substantial reporting bias. Assuming children and adolescents as reference groups, healthy adults were characterized by a higher risk ratio [RR] for septal thickening (RR 3.878, 95% CI 1.253–12.000), nodular lesions (RR 20.197, 95% CI 1.286–317.082), and GGOs (RR 2.121, 95% CI 1.121–4.013). RSV cases are rarely assessed in terms of CT characteristics. Our study identified some specificities, suggesting that RSV infections evolve heterogeneous CT features in children/adolescents and adults, but the paucity of studies recommends a cautious appraisal.

Lupin alkaloids (LAs) represent a class of toxic secondary metabolites in plants, in particular in Lupinus spp.; they are produced as a defense mechanism due to their strong bitter taste and are very dangerous for human and animals. In this work, a sensitive and reliable high performance liquid chromatography—tandem mass spectrometry (HPLC-MS/MS) analytical method for the identification and quantification of thirteen lupin alkaloids was developed and validated according to FDA guidelines. Efficient extraction and clean-up steps, carried out by solid-phase extraction, were finely tuned on the basis of the characteristics of the analytes and lupin samples, providing good selectivity with minimized matrix interference. The effectiveness of the method was proven by the satisfactory recovery values obtained for most of the analytes and a matrix effect ≤23% for all tested levels. In addition, a sensitive and reliable determination of the target compounds was obtained; LOQs were between 1 and 25 µg Kg−1, i.e., below the requested maximum levels (<200 mg Kg−1). The method was applied to evaluate the LAs profile in different batches of raw L. albus L. samples, varying in size and across farming treatments. [ABSTRACT FROM AUTHOR]

Aflatoxins (AFs) are fungi secondary metabolites produced by the Aspergillus family. These compounds can enter the food chain through food contamination, representing a risk to human health. Commercial immunoaffinity columns are widely used for the extraction and cleanup of AFs from food samples; however, their high cost and large solvent consumption create a need for alternative strategies. In this work, an alternative strategy for producing molecularly imprinted polymers (MIPs) was proposed to extract aflatoxins AFB1, AFB2, AFG1, and AFG2 from complex food samples, using liquid chromatography coupled with tandem mass spectrometry (LC–MS/MS). The MIPs were synthesized via a low-cost and rapid (5 min) sonochemical free-radical polymerization, using 1-hydroxy-2-naphthoic acid as a dummy template. MIPs-based solid phase extraction performance was tested on 17 dietary supplements (vegetables, fruits, and cereals), obtaining appreciable recovery rates (65–90%) and good reproducibility (RSD ≤ 6%, n = 3); the selectivity towards other mycotoxins was proved and the data obtained compared with commercial immunoaffinity columns. The proposed strategy can be considered an alternative affordable approach to the classical immunoaffinity columns, since it is more selective and better performing. [ABSTRACT FROM AUTHOR]

Introduction: The COVID‐19 Anxiety Syndrome Scale (C‐19ASS) is a quick and reliable scale assessing dysfunctional coping strategies activated in response to COVID‐19 fear and threat. The present study aimed to provide a preliminary validation of the Italian version of the C‐19ASS and investigated whether the C‐19ASS would mediate the relationship between the Big Five personality traits and psychological outcomes. Method: In Study 1, a community sample of 271 participants completed the Italian version of the C‐19ASS and results were subjected to a Principal Component Analysis. In study 2, a community sample of 484 participants completed the Italian version of the C‐19ASS and a series of measures assessing COVID‐19 anxiety, COVID‐19 fear, functional impairment, personality traits, depression, generalized anxiety and health anxiety. Internal consistency, concurrent and incremental validity were assessed. Path analyses were run. Results: Factor analysis identified a two‐factor solution (i.e., C‐19ASS Perseveration and C‐19ASS Avoidance) and confirmatory factor analysis suggested a two‐factor model best fits the data. The Italian version of the C‐19ASS showed good internal consistency. There was also evidence of convergent validity and incremental validity. Path analyses showed that C‐19ASS Perseveration mediates the relationship between emotional stability and psychological symptoms (depression, generalized anxiety and health anxiety). Conclusion: The Italian version of the C‐19ASS appears to be a reliable and valid measure of the COVID‐19 anxiety syndrome. The COVID‐19 anxiety syndrome could be a suitable therapeutic target to reduce psychological symptoms typically linked to pandemic events, such as depression generalized anxiety and health anxiety.

Cognitive behavioral therapy (CBT) approaches use case formulation procedures based on the diathesis–stress conceptualization model, arranged in two dimensions: emotional vulnerability (present in a patient's consciousness in terms of core beliefs) and coping strategies. Nevertheless, despite its pivotal role, there are a limited number of validation studies for this model. Life themes and semi-adaptive plans: Implications of biased beliefs, elicitation and treatment (LIBET) is a CBT case formulation method grounded on the CBT diathesis–stress model that aims to help validate the CBT case formulation model, and, in particular, its bidimensional arrangement. In LIBET, the two classic CBT dimensions are called "life themes," which are mental states of focused attention to emotional sensitivities represented as core beliefs in consciousness, and "semi-adaptive plans," which are the rigid management strategies of "life themes" implemented by adopting coping strategies such as anxious safety behaviors, compulsive controls and aggressive or rewarding strategies. The study uses quantitative textual analysis to validate the LIBET procedure in a clinical sample. The investigation discusses the extent to which the results can be considered a validation of the arrangement of the general CBT diathesis–stress model in the two dimensions of core beliefs and coping strategies.

Polyphenols (PCs) are a numerous class of bioactive molecules and are known for their antioxidant activity. In this work, the potential of the quadrupole/linear ion trap hybrid mass spectrometer (LIT-QqQ) was exploited to develop a semi-untargeted method for the identification of polyphenols in different food matrices: green coffee, Crocus sativus L. (saffron) and Humulus lupulus L. (hop). Several conjugate forms of flavonoids and hydroxycinnamic acid were detected using neutral loss (NL) as a survey scan coupled with dependent scans with enhanced product ion (EPI) based on information-dependent acquisition (IDA) criteria. The presented approach is focused on a specific class of molecules and provides comprehensive information on the different conjugation models that are related to specific base molecules, thus allowing a quick and effective identification of all possible combinations, such as mono-, di-, or tri-glycosylation or another type of conjugation such as quinic acid esters.

In the present work, Cannabis sativa L. cv Futura 75 inflorescences, cultivated in the Abruzzo territory, were characterized for their volatile fraction through SPME-GC-MS. In addition, the essential oil extracted from these inflorescences was investigated for the antioxidant potentialities and for the terpenic profile. The antibacterial activity of hemp essential oil (HEO) against some pathogenic and spoilage microorganisms isolated from food was also evaluated by determining the minimal inhibitory concentration (MIC) and the minimum bactericidal concentration (MBC). The results showed significant antioxidant capacity (DPPH: 63.38 ± 0.08 mg TE/g HEO; FRAP: 438.52 ± 6.92 mg TE/g HEO) alongside good antibacterial activity against Gram-positive bacteria such as S. aureus and L. monocytogenes (MIC 1.25-5 µL/mL). The results obtained suggest that hemp essential oil can inhibit or reduce bacterial growth, also exerting antioxidant activity, and therefore it can find an advantageous application in the food processing field.

Background and aims: FoMO has been considered a predisposing factor toward excessive internet use, and a great deal of literature has investigated the link between FoMO and internet use. However, there is still a lack of cohesion in the literature. Methods: The current study have been conducted and reported in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Results: In the current systematic review and meta-analysis of 86 effect-sizes, representative of 55,134 participants (Meanage = 22.07, SD = 6.15, females = 58.37%), we found that the strength of the trait FoMO-internet use association significantly varies from r = 0.11 to r = 0.63. In some populations, FoMO appears to increase with age and it is reverse in other populations. Facebook use was unrelated to FoMO in some populations, and higher FoMO was linked with stopping Instagram use for some individuals. The FoMO-internet use association was independent of their severity, as the interaction was not significant, and this association was neither linear nor curvilinear. The FoMO-internet use association does not appear to be associated with depressive, anxiety, and stress symptoms or level of life satisfaction. The COVID-19 pandemic was the only significant moderator of the FoMO-internet use association, strengthening this relationship. Discussion and Conclusions: FoMO demonstrates a considerable role in internet use; however, there is no evidence of interaction or bi-directional association between the mentioned. Overall, we still don't know what factors contribute to individuals exhibiting distinct patterns in the FoMO-internet use association. [ABSTRACT FROM AUTHOR]

Background: Literature has pointed out a probable association between metacognitive beliefs and eating disorders. To date, no study has synthetized all research exploring the differences or similarities in metacognitive beliefs across different eating disorders diagnoses and eating problems. Aims: To review the evidence on metacognitive beliefs across the spectrum of eating disorders and eating behaviours. Method: A comprehensive search was conducted on PubMed and PsycInfo. The search terms used were: 'eating disorders/anorexia/bulimia/binge eating disorder/binge eating' AND 'metacognitions/metacognitive beliefs'. A manual search of reference lists was also run. Results: Eleven studies were identified. Anorexia Nervosa was broadly characterized by higher levels of metacognitive beliefs compared to the general population, particularly negative beliefs about worry and beliefs about the need to control thoughts. Positive beliefs about worry were higher in Anorexia Nervosa compared to Bulimia Nervosa and Eating Disorder Not Otherwise Specified, and in Bulimia Nervosa compared to Eating Disorder Not Otherwise Specified. Negative beliefs about worry were higher in Anorexia Nervosa compared to Bulimia Nervosa. Cognitive self‐consciousness was higher in Anorexia Nervosa compared to Bulimia Nervosa and Eating Disorder Not Otherwise Specified. Conclusions: Metacognitive beliefs appear to be implicated in eating disorders and eating behaviours. [ABSTRACT FROM AUTHOR]

Research has shown that metacognition may play a role in problem eating. In this study we explored whether aspects of metacognition are relevant to the understanding of binge eating in patients with Binge Eating Disorder. We aimed to ascertain: (1) the presence of metacognitive beliefs about binge eating; (2) the goal of, and stop signal for, binge eating; and (3) the impact of binge eating on self-consciousness. Ten Binge Eating Disorder patients took part in the study and were assessed using the metacognitive profiling semi-structured interview. Results suggested that all patients endorsed both positive and negative metacognitive beliefs about binge eating. The goals of binge eating were stop thinking about personal concerns and improve emotional state. All patients reported that they did not know when these goals had been reached. The stop signals for binge eating included physical discomfort, beliefs about binge eating not being the best way to solve problems, and environmental stimuli. All patients also confirmed that a reduction in self-consciousness occurred during a binge eating episode. The results of this study confirm that metacognition may indeed be relevant to the understanding of Binge Eating Disorder. [ABSTRACT FROM AUTHOR]

Background: It has been proposed that repetitive negative thinking (worry and rumination) may be more common among adults who have been exposed to childhood adverse experiences, leading to emotional disorders and other adverse outcomes. The current study aims to present a comprehensive evaluation of the literature examining the relationship between the exposure to childhood adversities, repetitive negative thinking and clinical outcomes in adulthood. Methods: In accordance with Preferred Reporting Items for Systematic Reviews and Meta‐Analyses (PRISMA) criteria, a search was conducted on PubMed and Ebsco. A manual search of reference lists was also run. Search terms were 'childhood adversity/childhood abuse/childhood neglect/early loss event AND worry or rumination'. Results: A total of 18 studies met the inclusion criteria. In both non‐clinical and clinical populations, worry and rumination seem to be common among adults exposed to childhood abuse or childhood neglect. Among adults who have been exposed to childhood adversities, rumination seems to be associated with worse clinical outcomes such as severe psychiatric symptoms, depression, dysphoria, suicidal ideation, cognitive complaints, post‐traumatic stress symptoms and aggression. Conclusion: Early experiences of abuse and neglect may be associated with a tendency to engage in repetitive negative thinking, such as worry and rumination, in adulthood. Among adults, with a history of childhood adversities, tailored treatment to reduce repetitive negative thinking should be considered. [ABSTRACT FROM AUTHOR]

Apennines genepì (Artemisia umbelliformis Lam. subsp. eriantha), is a high-altitude plant endangered by illegal and indiscriminate harvesting to produce the homonymous liqueur. Even if synthetic seeds represented a valid propagation technique to respond to this threat, this technology still requires methods to improve the low germination and plantlet development rates. The aim of the present study was to evaluate the suitability of the bacterial consortium formed by Azospirillum brasilense, Gluconacetobacter diazotrophicus, Burkholderia ambifaria, and Herbaspirillum seropedicae, as an enrichment agent of Apennines Genepì synthetic seeds. To evaluate the effectiveness as an improving agent, the consortium was incorporated in the synthetic seeds, compared to a control, and followed until ex vitro cultivations. Plants were evaluated for their growth and development parameters, total phenolic and flavonoid contents, antioxidant properties, polyphenolic compounds concentrations, and volatile fractions. The results demonstrated that the investigated consortium is a good candidate as an enrichment agent in synthetic seed technology. The rhizobacterial presence induced an improved response in plant propagation and the acclimatization process. Plant quality was also enhanced, with an increased accumulation of plant secondary metabolites and higher antioxidant capacity. The investigated bacterial consortium is a good candidate as an enrichment agent in synthetic seed technology. Plant clones can be translocated for species conservation and also commercialized to reduce the illegal and undiscerning collections. [ABSTRACT FROM AUTHOR]

Within the unavoidable variability of various origins in the characteristics of essential oils, the aim of this study was to evaluate the effect of the distillation time on the chemical composition and biological activity of Cannabis sativa essential oils (EOs). The dry inflorescences came from Carmagnola, Kompolti, Futura 75, Gran Sasso Kush and Carmagnola Lemon varieties from Abruzzo region (Central Italy), the last two being new cultivar here described for the first time. EOs were collected at 2 h and 4 h of distillation; GC/MS technique was applied to characterize their volatile fraction. The EOs were evaluated for total polyphenol content (TPC), antioxidant capacity (AOC) and antimicrobial activity against food-borne pathogens and spoilage bacteria. The time of distillation particularly influenced EOs chemical composition, extracting more or less terpenic components, but generally enriching with minor sesquiterpenes and cannabidiol. A logical response in ratio of time was observed for antioxidant potential, being the essential oils at 4 h of distillation more active than those distilled for 2 h, and particularly Futura 75. Conversely, except for Futura 75, the effect of time on the antimicrobial activity was variable and requires further investigations; nevertheless, the inhibitory activity of all EOs against Pseudomonas fluorescens P34 was an interesting result.

The role of worry and rumination in eating disorders (EDs) is controversial. This meta-analysis of the literature is aimed at clarifying the relationship between repetitive negative thinking (RNT) and EDs. In accordance with the PRISMA criteria, a comprehensive search of the literature was conducted on PubMed and PsycInfo from inception to March 2021. Search terms: "eating disorder/anorexia/bulimia/binge eating disorder" AND "worry/rumination/brooding/repetitive thinking". A manual search of reference lists was also run. Forty-three studies were included. RNT was found to be associated with anorexia, bulimia, and binge eating disorder. A moderating effect was found for "presence/absence ED diagnosis" and "subtype of ED symptom". ED patients showed higher RNT than the general population. No differences were observed for age or between worry and rumination in the magnitude of their association with EDs. [ABSTRACT FROM AUTHOR]

Appropriate and standardized techniques for the extraction of secondary metabolites with interesting biological activity from plants are required. In this work, a comparison of different conventional and unconventional extraction techniques (maceration—M, Soxhlet—S, ultrasound assisted extraction—UAE, and rapid solid-liquid dynamic extraction—RSLDE) was investigated. Bioactive compounds were extracted from Thymus vulgaris L. (thyme), Cannabis sativa L. (industrial hemp) and Coriandrum sativum L. (coriander) and chemically characterized for their volatile fraction and polyphenolic content by means of gas chromatography-mass spectrometry (GC-MS) and high performance liquid chromatography-ultraviolet (HPLC-UV). Linalool (48.19%, RSLDE) and carvacrol (21.30%, M) for thyme, caryophyllene (54.78%, S) and humulene (14.13%, S) for hemp, and linalool (84.16%, RSLDE) for coriander seeds were the main compounds among terpenes, while thyme was the richest source of polyphenols with rosmarinic acid (51.7 mg/g dry extract-S), apigenin (7.6 mg/g dry extract-S), and luteolin (4.1 mg/g dry extract-UAE) being the most abundant. In order to shed light on their potential as natural food preservatives, the biological activity of the extracts was assessed in terms of antioxidant activity (2,2′-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid—ABTS˙+, ferric reducing antioxidant power—FRAP, 2,2-diphenyl-1-picrylhydrazyl—DPPH˙ assays) and phenolic content (Folin–Ciocâlteu method). For thyme, Soxhlet extracts showed best performances in FRAP and ABTS˙+ assays (74 mg TE/g dry extract and 134 mg TE/g dry extract, respectively), while Soxhlet and RSLDE extracts recorded similar activity in DPPH˙ (107–109 mg TE/g dry extract). For hemp and coriander, indeed, RSLDE extracts accounted for higher antioxidant activity as evidenced by FRAP (80 mg TE/g dry extract and 18 mg TE/g dry extract, respectively) and ABTS˙+ (557 mg TE/g dry extract and 48 mg TE/g dry extract, respectively) assays. With respect to DPPH˙, the best results were observed for UAE extracts (45 mg TE/g dry extract and 220 mg TE/g dry extract, respectively). Our findings suggest that all the investigated techniques are valid extraction methods to retain bioactive compounds and preserve their activity for application in food and pharmaceutical formulations. Among them, the innovative RSLDE stands out for the slightly higher antioxidant performances of the extracts, coupled with the facility of use and standardization of the extraction process.

In this work, the concentration of nine cannabinoids, six neutral cannabinoids (THC, CBD, CBC, CBG, CBN and CBDV) and three acidic cannabinoids (THCA CBGA and CBDA), was used to identify the Italian retailers of Cannabis sativa L. (hemp), reinforcing the idea that the practice of categorizing hemp samples only using THC and CBD is inadequate. A high-performance liquid chromatography/high-resolution mass spectrometry (HPLC-MS/MS) method was developed for screening and simultaneously analyzing the nine cannabinoids in 161 hemp samples sold by four retailers located in different Italian cities. The hemp samples dataset was analyzed by univariate and multivariate analysis with the aim to identify the hemp retailers without any other information on the hemp samples like Cannabis strains, seeds, soil and cultivation characteristics, geographical origin, product storage, etc. The univariate analysis highlighted that the hemp samples could not be differentiated by using any of the nine cannabinoids analyzed. To evaluate the real efficiency of the discrimination among the four hemp retailers a partial least squares discriminant analysis (PLS-DA) was applied. The PLS-DA results showed a very good discrimination between the four hemp retailers with an explained variance of 100% and low classification errors in both calibration (5%) and cross validation (6%). A total of 92% of the hemp samples were correctly classified by the cannabinoid variables in both fitting and cross validation. This work contributed to show that an analytical method coupled with multivariate analysis can be used as a powerful tool for forensic purposes. [ABSTRACT FROM AUTHOR]
