RESUMEN

Biopesticides are natural compounds considered more safe and sustainable for the environment. Spinosad (SPI) is a bioinsecticide used in marketed worldwide, to eradicate a variety of pests. This study aimed to assess the impacts of the SPI on the non-target organism zebrafish (Danio rerio). Several concentrations of SPI were tested to evaluate the acute (0.07-1.0mg/L) and chronic (0.006-0.100mg/L) ecotoxicological effects. To evaluate sub-individual effects, antioxidant defense, lipid peroxidation, energy sources, and cholinergic biomarkers were quantified. In both exposures, SPI induced significant effects on antioxidant defense indicating oxidative stress, disrupting energy pathways, and exhibiting neurotoxic effects, under environmentally relevant conditions. Integrated Biomarker Response (IBRv2) showed that with increasing SPI concentrations, an increase in impacts on organisms was recorded. This study demonstrates the vulnerability of a non-target organism to SPI, a bioinsecticide considered environmentally safe. Further research is essential to fully understand the implications of spinosad to aquatic biota.

RESUMEN

Broad variations in dietary and physical activity patterns are part of nutritional transition concept. An additional nutritional transition has as main characteristic the change of consumption of processed foods for ultra-processed foods (UPF). This study aims to evaluate trends of UPF availability in Portuguese population and its association with diet-related non-communicable diseases (NCD) health indicators. This ecological study used data from the Household Budget Surveys conducted by the National Statistics Institute each 5 years within a national representative sample of households. The percentage of UPF was calculated based on the total daily amount of food and beverages available per capita (in grams). Data from the years 1990, 1995, 2000 and 2005 were used, which were retrieved from DAFNE-Anemos Software. NCD age-standardised mortality, prevalence and incidence were obtained from the Global Burden of Disease database, for the years 2000, 2005, 2010 and 2015. Between 1990 and 2005, the UPF availability increased from 3·9 % to 13·8 %. Over the years, almost all food and beverages categories increased the UPF availability contribution, mainly noticeable for milk, sugar, cereal and meat products. Positive correlations were observed between UPF availability and digestive diseases both in prevalence (r = 0·062; P = 0·037) and incidence (r = 0·005; P = 0·010) measures. Neoplasms incidence also showed positive correlation with UPF availability (r = 0·002; P = 0·012). Trends in UPF availability in Portugal increased exponentially. At the same time, there is a trend towards a decrease in unprocessed and processed food availability. The Portuguese population should be made aware of the health risks resulting from excessive consumption of UPF.

RESUMEN

BACKGROUND: Moral distress (MD) and moral injury (MI) are related constructs describing the negative consequences of morally challenging stressors. Despite growing support for the clinical relevance of these constructs, ongoing challenges regarding measurement quality risk limiting research and clinical advances. This study summarizes the nature, quality, and utility of existing MD and MI scales, and provides recommendations for future use. METHOD: We identified psychometric studies describing the development or validation of MD or MI scales and extracted information on methodological and psychometric qualities. Content analyses identified specific outcomes measured by each scale. RESULTS: We reviewed 77 studies representing 42 unique scales. The quality of psychometric approaches varied greatly across studies, and most failed to examine convergent and divergent validity. Content analyses indicated most scales measure exposures to potential moral stressors and outcomes together, with relatively few measuring only exposures (n = 3) or outcomes (n = 7). Scales using the term MD typically assess general distress. Scales using the term MI typically assess several specific outcomes. CONCLUSIONS: Results show how the terms MD and MI are applied in research. Several scales were identified as appropriate for research and clinical use. Recommendations for the application, development, and validation of MD and MI scales are provided.

RESUMEN

INTRODUCTION: Respiratory therapists (RTs) faced morally distressing situations throughout the COVID-19 pandemic, including working with limited resources and facilitating video calls for families of dying patients. Moral distress is associated with a host of adverse psychological and functional outcomes (e.g. depression, anxiety, symptoms of posttraumatic stress disorder [PTSD] and functional impairment) and consideration of position departure. The purpose of this study was to understand the impact of moral distress and its associated psychological and functional outcomes on consideration to leave a clinical position among Canadian RTs during the COVID-19 pandemic. METHODS: Canadian RTs (N = 213) completed an online survey between February and June 2021. Basic demographic information (e.g. age, sex, gender) and psychometrically validated measures of moral distress, depression, anxiety, stress, PTSD, dissociation, functional impairment, resilience and adverse childhood experiences were collected. RESULTS: One in four RTs reported considering leaving their position. RTs considering leaving reported elevated levels of moral distress and adverse psychological and functional outcomes compared to RTs not considering leaving. Over half (54.5%) of those considering leaving scored above the cut-off for potential diagnosis of PTSD. Previous consideration to leave a position and having left a position in the past each significantly increased the odds of currently considering leaving, along with system-related moral distress and symptoms of PTSD, but the contribution of these latter factors was small. CONCLUSIONS: Canadian RTs considering leaving their position reported elevated levels of distress and adverse psychological and functional outcomes, yet these individual-level factors appear unlikely to be the primary factors underlying RTs' consideration to leave, because their effects were small. Further research is required to identify broader, organizational factors that may contribute to consideration of position departure among Canadian RTs.

RESUMEN

The growing concern over the environmental impacts of industrial chemicals on aquatic ecosystems has prompted increased attention and regulation. Aromatic amines have drawn scrutiny due to their potential to disturb aquatic ecosystems. 4-chloroaniline and 3,4-dichloroaniline are chlorinated derivatives of aniline used as intermediates in the synthesis of pharmaceuticals, dyes, pesticides, cosmetics, and laboratory chemicals. While industrial applications are crucial, these compounds represent significant risks to aquatic environments. This article aims to shed light on aromatic amines' ecological and ecotoxicological impacts on aquatic ecosystems, given as examples 4-chloroaniline and 3,4-dichloroaniline, highlighting the need for stringent regulation and management to safeguard water resources. Moreover, these compounds are not included in the current Watch List of the Water Framework Directive, though there is already some information about aquatic ecotoxicity, which raises some concerns. This paper primarily focuses on the inherent environmental problem related to the proliferation and persistence of aromatic amines, particularly 4-chloroaniline and 3,4-dichloroaniline, in aquatic ecosystems. Although significant research underscores the hazardous effects of these compounds, the urgency of addressing this issue appears to be underestimated. As such, we underscore the necessity of advancing detection and mitigation efforts and implementing improved regulatory measures to safeguard the water bodies against these potential threats.

RESUMEN

Caffeine (CAF) exposures have been shown to cause several pharmacological and biological effects in target and non-target organisms. Although there are already several ecotoxicological studies with CAF in non-target organisms, they are focused on marine organisms, with relevant concentrations in these ecosystems, therefore, less ecologically relevant to freshwater ecosystems (the main ecoreceptor of this type of anthropogenic contaminant). The present study aimed to assess the chronic effects (28 days) of sub-lethal and environmentally relevant concentrations of CAF (0.16, 0.42, 1.09, 2.84, 7.40, 19.23, and 50 µg/L) in Danio rerio. Biochemical endpoints as biomarkers of antioxidant defense, biotransformation, lipid peroxidation, energy sources, and neurotransmission were assessed. CAF exposure induced alterations in antioxidant defenses (superoxide dismutase and glutathione reductase activities, and glutathione content) preventing lipid peroxidation. Lactate dehydrogenase activity decreased in all the concentrations tested, while acetylcholinesterase activity was only affected by the highest concentrations tested (19.23 and 50 µg/L). We also utilized a multi-biomarker approach (Integrated Biomarker Response version 2, IBRv2) to investigate the effects of CAF in the dispersion scope of individual biochemical responses of D. rerio. IBRv2 showed that the concentration of 50 µg/L promotes the highest stress. However, the results showed that CAF induced disturbances in the metabolic pathways studied in D. rerio. These results demonstrated the toxic effects of CAF on freshwater fish, compromising their physiological functions and evidencing the need for monitoring the residues of CAF released into the inland aquatic environments. Furthermore, this research evidence that phylogenetically and physiologically different species may present different biological responses with concern for ecologically relevant environmental conditions. In this sense, the present study generated ecotoxicologically relevant data, that can be considered by environment regulators, since the here-endpoints evaluated showed sensitivity and consistency in the evaluation of caffeine risks in freshwater environments.

RESUMEN

The stereotypical progression of Tau pathology during Alzheimer disease has been attributed to trans-neuronal spreading of misfolded Tau proteins, followed by prion-like templated aggregation of Tau. The nature of Tau and the cellular mechanisms of Tau spreading are still under debate. We hypothesized that Tau's propensity for aggregation would correlate with its ability to spread across synapses and propagate pathology. To study the progressive propagation of Tau proteins in brain regions relevant for Alzheimer disease, we used mice expressing near-physiological levels of full-length human Tau protein carrying pro-aggregant (TauΔK280, TauΔK) or anti-aggregant (TauΔK280-PP, TauΔK-PP) mutations in the entorhinal cortex (EC). To enhance Tau expression in the EC, we performed EC injections of adeno-associated virus (AAV) particles encoding TauΔK or TauΔK-PP. The brains of injected and non-injected EC/TauΔK and EC/TauΔK-PP mice were studied by immunohistological and biochemical techniques to detect Tau propagation to dentate gyrus (DG) neurons and Tau-induced pathological changes. Pro- and anti-aggregant mice had comparable low transgene expression (~0.2 times endogenous mouse Tau). They accumulated human Tau at similar rates and only in expressing EC neurons, including their axonal projections of the perforant path and presynaptic terminals in the molecular layer of the DG. Pro-aggregant EC/TauΔK mice showed misfolded Tau and synaptic protein alterations in EC neurons, not observed in anti-aggregant EC/TauΔK-PP mice. Additional AAV-mediated expression of TauΔK or TauΔK-PP in EC/TauΔK or EC/TauΔK-PP mice, respectively, increased the human Tau expression to ~0.65 times endogenous mouse Tau, with comparable spreading of TauΔK and TauΔK-PP throughout the EC. There was a low level of transcellular propagation of Tau protein, without pathological phosphorylation or misfolding, as judged by diagnostic antibodies. Additionally, TauΔK but not TauΔK-PP expression induced hippocampal astrogliosis. Low levels of pro- or anti-aggregant full-length Tau show equivalent distributions in EC neurons, independent of their aggregation propensity. Increasing the expression via AAV induce local Tau misfolding in the EC neurons, synaptotoxicity, and astrogliosis and lead to a low level of detectable trans-neuronal spreading of Tau. This depends on its concentration in the EC, but, contrary to expectations, does not depend on Tau's aggregation propensity/misfolding and does not lead to templated misfolding in recipient neurons.

RESUMEN

The relationship between salivary proteome and dietary habits was studied in previous works, where a relationship between salivary proteins like cystatins and polyphenol/tannin levels in diet was observed. However, it remains to be elucidated if this association results from an effect of polyphenol-rich food ingestion on saliva composition. The aim of this work was to test the effects of apple intake on the saliva proteome, both in the short and medium term (after 4 days of continuous intake). By incubating saliva samples with apple phenolic-rich extract, protein bands containing α-amylase, S-type cystatins, and proline-rich proteins (PRPs) appeared in the fraction that precipitated, showing the potential of these (poly)phenols to precipitate salivary proteins. Among these, it was salivary cystatins that presented changes in their levels both in the saliva samples collected immediately after apple intake and in the ones collected after 4 days of intake of an extra amount of apple. These results support the thought that intake is reflected in the salivary proteome. The effect of a polyphenol-rich food, like the apple, on salivary cystatin levels is in line with results observed in animal models and, due to the involvement of these proteins in oral food perception, it would be interesting to explore in future studies the effect of these changes on sensory perception and acceptance of polyphenol-rich food.

RESUMEN

Background: Hepatocellular adenoma (HCA) is an uncommon solid, solitary, benign liver lesion that develops in an otherwise normal-appearing liver. Hemorrhage and malignant transformation are the most important complications. Risk factors for malignant transformation include advanced age, male gender, use of anabolic steroids, metabolic syndrome, larger lesions, and beta-catenin activation subtype. The identification of higher risk adenomas enables the selection of patients most suitable for aggressive treatment and those who benefit with surveillance, minimizing the risks for these predominantly young patients. Case Presentation. We present the case of a 29-year-old woman with a history of oral contraceptive intake for 13 years, which was sent to evaluation in our Hepato-Bilio-Pancreatic and Splenic Unit because of a large nodular lesion in segment 5 of the liver, compatible with HCA, and was proposed to surgical resection. Histological and immunohistochemical investigation revealed an area with atypical characteristics, suggesting malignant transformation. Conclusions: HCAs share similar imaging characteristics and histopathological features with hepatocellular carcinomas; therefore, immunohistochemical and genetic studies assumes great importance to discriminate adenomas with malignant transformation. Beta-catenin, glutamine synthetase, glypican-3, and heat-shock protein 70 are promising markers to identify higher risk adenomas.

RESUMEN

Background: Moral injury (MI) has become a research and organizational priority as frontline personnel have, both during and in the years preceding the COVID-19 pandemic, raised concerns about repeated expectations to make choices that transgress their deeply held morals, values, and beliefs. As awareness of MI grows, so, too, does attention on its presence and impacts in related occupations such as those in public safety, given that codes of conduct, morally and ethically complex decisions, and high-stakes situations are inherent features of such occupations.Objective: This paper shares the results of a study of the presence of potentially morally injurious events (PMIEs) in the lived experiences of 38 public safety personnel (PSP) in Ontario, Canada.Method: Through qualitative interviews, this study explored the types of events PSP identify as PMIEs, how PSP make sense of these events, and the psychological, professional, and interpersonal impacts of these events. Thematic analysis supported the interpretation of PSP descriptions of events and experiences.Results: PMIEs do arise in the context of PSP work, namely during the performance of role-specific responsibilities, within the organizational climate, and because of inadequacies in the broader healthcare system. PMIEs are as such because they violate core beliefs commonly held by PSP and compromise their ability to act in accordance with the principles that motivate them in their work. PSP associate PMIEs, in combination with traumatic experiences and routine stress, with adverse psychological, professional and personal outcomes.Conclusion: The findings provide additional empirical evidence to the growing literature on MI in PSP, offering insight into the contextual dimensions that contribute to the sources and effects of PMIEs in diverse frontline populations as well as support for the continued application and exploration of MI in the PSP context.


The objective of this study was to understand the types of events that Canadian public safety personnel (PSP) experience as potentially morally injurious events (PMIEs) as well as the impacts that they associate with these events.The findings illuminate that contextual dimensions are significant in the origin of PMIEs, which PSP experience in the completion of routine duties, because of the organizational culture, or as a result of issues in the broader healthcare system, which led to many negative consequences in their personal and professional lives.PMIEs reduced the trust PSP had in their leadership and the healthcare system to protect the public and themselves, were associated with feelings of anger, frustration, resignation, and helplessness, and connected to internal struggles marked by inner conflict and the erosion of self-concept.

RESUMEN

BACKGROUND: Given the highly stressful environment surrounding the SARS-CoV-2 pandemic, healthcare workers (HCW) and public safety personnel (PSP) are at an elevated risk for adverse psychological outcomes, including posttraumatic stress disorder (PTSD) and alcohol/substance use problems. As such, the study aimed to identify associations between PTSD severity, related dissociation and emotion dysregulation symptoms, and alcohol/substance use problems among HCWs and PSP. METHODS: A subset of data (N = 498; HCWs = 299; PSP = 199) was extracted from a larger study examining psychological variables among Canadian HCWs and PSP during the pandemic. Structural equation modelling assessed associations between PTSD symptoms and alcohol/substance use-related problems with dissociation and emotion dysregulation as mediators. RESULTS: Among HCWs, dissociation fully mediated the relation between PTSD and alcohol-related problems (indirect effect ß = .133, p = .03) and emotion dysregulation partially mediated the relation between PTSD and substance-related problems (indirect effect ß = .151, p = .046). In PSP, emotion dysregulation fully mediated the relation between PTSD and alcohol-related problems (indirect effects ß = .184, p = .005). For substance-related problems among PSP, neither emotion dysregulation nor dissociation (ps >.05) had any effects. CONCLUSION: To our knowledge, this is the first study examining associations between PTSD severity and alcohol/substance use-related problems via mediating impacts of emotion dysregulation and dissociation among HCWs and PSP during the SARS-CoV-2 pandemic. These findings highlight dissociation and emotion dysregulation as important therapeutic targets for structured interventions aimed at reducing the burden of PTSD and/or SUD among Canadian HCWs or PSP suffering from the adverse mental health impacts of the SARS-CoV-2 pandemic.


Among healthcare workers, dissociation mediated relation between posttraumatic stress disorder (PTSD) severity and alcohol-related problems and emotion dysregulation mediated relation between PTSD severity and substance-related problems.Among public safety personnel, emotion dysregulation mediated relation between PTSD severity and alcohol-related problems. Neither dissociation nor emotion dysregulation mediated relation between PTSD severity and substance-related problems.Results underscore dissociation and emotion dysregulation as potential key therapeutic targets for intervention for healthcare workers and public safety personnel struggling with PTSD and comorbid alcohol/substance use-related problems.

RESUMEN

Due to global warming and extreme weather events, estuarine and coastal ecosystems are facing sudden fluctuations in salinity. These ecosystems are also threatened by organic and inorganic compounds that increase water pollution. Metformin is an antidiabetic drug commonly used by patients with type-2 diabetes, and an increase in environmental concentration has been recorded. To better understand the impacts of these two stressors on aquatic organisms, this study assessed: 1) the acute (96 h) ecotoxicological effects (antioxidant and biotransformation capacity, oxidative damage, energetic reserves, and protein content, neurotoxicity) induced by a range of metformin concentrations in Gambusia holbrooki under different salinities (17, 24, 31 expressed as Practical Salinity Units - PSU); and 2) the same endpoints after chronic exposure (28 d) under a range of metformin concentrations at a salinity of 17. The results obtained from the acute exposure showed interactions between salinity and metformin in G. holbrooki superoxide dismutase (SOD) activity, body protein, and glycogen (GLY) contents. The results revealed that an increase in salinity can modulate the response of G. holbrooki to metformin. Chronically exposed organisms showed that metformin led to a significant decrease in SOD activity at most of the tested concentrations (0.5, 1.0, and 10 µg/L). In addition, glutathione S-transferases increased and glutathione peroxidase activity decreased significantly at concentrations of metformin of 5 and 10 at the µg/L, respectively. Therefore, overall, metformin can lead to potential oxidative stress in G. holbrooki the highest metformin concentrations tested and the GLY content in G. holbrooki increased after exposure to metformin concentrations of 0.5, 1.0 and 5.0 µg/L. Published studies have already shown that metformin alone can lead to oxidative damage in aquatic species, endangering the biodiversity of aquatic ecosystems. Therefore, additional ecotoxicological studies should be performed to characterize if other metformin concentrations combined with salinity, or other climate change-related factors, might impact non-target species. Standard toxicity bioassays may not be predictive of actual pollutants (e.g. metformin) toxicity under variable environmental conditions, and the investigation of a wider range of exposure conditions could improve the accuracy of chemical risk assessments.

RESUMEN

BACKGROUND: Healthcare providers (HCPs) may be at elevated risk for moral injury due to increased exposure to potentially morally injurious events (PMIEs) throughout the COVID-19 pandemic. Identifying PMIEs experienced during the COVID-19 pandemic is a critical first step for understanding moral injury in HCPs. Accordingly, the purpose of the present study was to gain a deeper understanding of the work-related PMIEs experienced by HCPs in Canada during the pandemic. METHODS: Canadian HCPs completed an online survey between February and December 2021 about mental health and functioning, including demographics and the Moral Injury Outcome Scale (MIOS). We conducted a qualitative thematic analysis of PMIEs described extemporaneously by HCPs in the open-text field of the MIOS. RESULTS: One-hundred and twenty-four (N = 124) HCPs were included in analysis. Eight PMIE-related themes were identified, comprising patients dying alone; provision of futile care; professional opinion being ignored; witnessing patient harm; bullying, violence and divided opinions; resources and personal protective equipment; increased workload and decreased staffing; and conflicting values. CONCLUSIONS: Understanding broad categories of PMIES experienced by Canadian HCPs during the COVID-19 pandemic provides an opportunity to enhance cultural competency surrounding their experiences which will aid the development of targeted prevention and intervention approaches.

RESUMEN

Introduction: Healthcare professionals (HCPs) appear to be at increased risk for negative psychological outcomes [e.g. depression, anxiety, post-traumatic stress disorder (PTSD), moral distress] and associated impacts on functioning throughout the COVID-19 pandemic. HCPs working on designated COVID-19 units may be further impacted than their colleagues not on these units given added demands of patient care and risk of contracting COVID-19. Little is known, however, about the mental health and functioning of specific professional groups beyond nurses and physicians, including respiratory therapists (RTs), over the course of the pandemic. Accordingly, the purpose of the present study was to characterize the mental health and functioning of Canadian RTs and compare profiles between RTs working on and off designated COVID-19 units.Methods: Canadian RTs completed an online survey between February and June 2021, including demographic information (e.g. age, sex, gender,) and measures of depression, anxiety, stress, PTSD, moral distress and functional impairment. Descriptive statistics, correlation analyses and between-groups comparisons were conducted to characterize RTs and compare profiles between those on and off COVID-19 units.Results: Two hundred and eighteen (N = 218) RTs participated in this study. The estimated response rate was relatively low (6.2%) Approximately half of the sample endorsed clinically relevant symptoms of depression (52%), anxiety (51%) and stress (54%) and one in three (33%) screened positively for potential PTSD. All symptoms correlated positively with functional impairment (p's < .05). RTs working on COVID-19 units reported significantly greater patient-related moral distress compared to those not on these units (p < .05).Conclusion: Moral distress and symptoms of depression, anxiety, stress and PTSD were prevalent among Canadian RTs and were associated with functional impacts. These results must be interpreted with caution given a low response rate, yet raise concern regarding the long-term impacts of pandemic service among RTs.


Research on RTs' mental health prior to and during the COVID-19 pandemic is scant, especially in comparison to other HCPs.RTs in the present study reported experiencing moral distress and clinically significant symptoms of depression, anxiety and PTSD, with associated functional impairment.One in three RTs screened positive for likely PTSD on the PCL-5.There is a need to provide RTs with adequate mental health supports and to understand the long-term impacts of pandemic service among RTs.

RESUMEN

For many, including military veterans and their families, support between individuals with shared lived experiences, or peer support, has long been utilized as a way to support each other through many different challenges. Building on other reviews and guided by the seven domains of well-being in the Canadian veteran well-being framework, the objective of this paper is to describe and catalogue the nature of peer support activities and related outcomes in the veteran, serving member, and family member populations. A scoping review following the five stages outlined by Arksey and O'Malley was conducted; it was guided by the question: What is currently known about peer support activities for veterans, serving members, and their families that has been evaluated in the literature? In total, 101 publications from 6 different countries were included in this review and catalogued based on publication characteristics, participant information, peer support activity information, and peer information. Peer support activities have the potential to positively influence the well-being of veterans, serving members, and their families on a holistic level across multiple domains. This scoping review highlights the existing gaps in the literature and provides an important foundation for future research on peer support for these populations, specifically in the Canadian context.

RESUMEN

Throughout the COVID-19 pandemic, healthcare workers (HCWs) have been exposed to highly stressful situations, including increased workloads and exposure to mortality, thus posing a risk for adverse psychological outcomes, including acute stress, moral injury, and depression or anxiety symptoms. Although several reports have sought to identify the types of coping strategies used by HCWs over the course of the pandemic (e.g., physical activity, religion/spirituality, meditation, and alcohol), it remains unclear which factors may influence HCWs' choice of these coping strategies. Accordingly, using a qualitative approach, the purpose of the present study was to gain a deeper understanding of the factors influencing HCWs' choice of coping strategies during the COVID-19 pandemic in Canada. Fifty-one HCWs participated in virtual, semi-structured interviews between February and June 2021. Interview transcripts were analysed through an inductive thematic approach, yielding two primary themes. First, HCWs described an ongoing shift in their approach to coping depending on their mental "bandwidth", ranging from "quick fix" to more "intentional effort" strategies to engage in proactive strategies to improve mental health. Second, many HCWs identified various barriers to desired coping strategies during the pandemic, including the preponderance of pandemic- and other circumstantial-related barriers. The findings from this study offer a unique understanding of the factors influencing HCWs' choice of coping strategies under novel and increased stress. This knowledge will be central to developing appropriate forms of support and resources to equip HCWs throughout and after the pandemic period, and in mitigating the potential adverse mental health impacts of this period of prolonged stress and potential trauma.

RESUMEN

Sweet cherry (Prunus avium L.) is a highly valued fruit, whose quality can be evaluated using several objective methodologies, such as calibre, colour, texture, soluble solids content (SSC), titratable acidity (TA), as well as maturity indexes. Functional and nutritional compounds are also frequently determined, in response to consumer demand. The aim of the present review is to clarify and establish quality evaluation parameters and methodologies for the whole cherry supply chain, in order to promote easy and faithful communication among all stakeholders. The use of near-infrared spectroscopy (NIRS) as a non-destructive and expeditious method for assessing some quality parameters is discussed. In this review, the results of a wide survey to assess the most common methodologies for cherry quality evaluation, carried out among cherry researchers and producers within the framework of the COST Action FA1104 'Sustainable production of high-quality cherries for the European market', are also reported. The standardisation of quality evaluation parameters is expected to contribute to the preservation and shelf-life extension of sweet cherries, and the valorisation of the whole supply chain.
