The effect of communication and implicit associations on consuming insects: An experiment in Denmark and Italy.

It has been widely noted that the introduction of insects in Westerns' diet might be a promising path towards a more sustainable food consumption. However, Westerns' are almost disgusted and sceptical about the eating of insects. In the current paper we report the results of an experiment conducted in two European countries-Denmark and Italy-different for food culture and familiarity with the topic of eating insects. We investigated the possibility to foster people's willingness to eat insect-based food through communication, also comparing messages based on individual vs. societal benefits of the eating of insects. Communication proved to be effective on intention and behaviour, and the societal message appeared to be more robust over time. The communication effect is significant across nation, gender, and previous knowledge about the topic. In addition, we investigated the impact of non-conscious negative associations with insects on the choice to eat vs. not eat insect-based food. Implicit attitudes proved to be a powerful factor in relation to behaviour, yet they did not impede the effectiveness of communication.

Neurodegenerative disorders are an inhomogeneous group of neurological diseases that affect a large part of the population because of the rise in life expectancy. Although clinical manifestations are important to make the correct diagnosis, the new advanced imaging technique represent a very useful tool for the diagnostic work-up.

[The cerebral perivascular spaces: review of the literature on diffuse or focal expansion]. / Gli spazi perivascolari encefalici: revisione della letteratura sulle dilatazioni focali o diffuse.

Virchow-Robin spaces (VRS) are pial-lined, interstitial fluid-filled structures that do not directly communicate with the subarachnoid space, accompany penetrating arteries and veins and can be visualized on magnetic resonance imaging. This article reviews the imageology characteristics, the functions, the causes and the relation with neurological disorders of VRS.

[Cytological diagnosis of lymph nodes by instrumental guide: ultrasonography and CT]. / La diagnosi citologica dei linfonodi con guida strumentale: ecografia e TC.

Imaging techniques, such as ultrasound imaging, computed tomography, positron emission tomography or magnetic resonance imaging, are highly accurate procedures for the detection of lymph node enlargement, but none of them has the same sensitivity in the biological definition and in the cause of enlargement. Therefore, a direct evaluation of corresponding lymph nodes is necessary in most cases and fine needle cytology (FNC) is one of the most frequently used techniques for this purpose. The same imaging procedures are often used to perform targeted biopsies including FNC. This study discusses procedures, indications, advantages and limitations of imaging techniques as a support to FNC.

[Ultrasound-guided biopsy of the testis: indications and results]. / Biopsie testicolari sotto guida ecografica: indicazioni e risultati.

Ultrasound examination of the testis is the imaging modality of choice for the evaluation of intratesticular focal lesions. In spite of its high sensibility, eco-Doppler-elastography is lacking of specificity in discrimination between benign and malign lesions, not always allowing us to make a definitive diagnosis of malignancy. When a diagnostic doubt persists, for such lesions that are indeterminate at clinical and radiological evaluation, it is possible to recur to ultrasound-guided testicular needle biopsy. This paper describes the main application scenarios of testicular fine-needle aspiration under ultrasound guidance and the experience in our institute.

Beyond Meat: Alternative Sources of Proteins to Feed the World.

Consumers' Preferences for Chicken Fed on Different Processed Animal Proteins: A Best-Worst Analysis in Italy.

The increase in meat consumption expected in the next decade will require more and more proteins for animal feeding. The recent amendments to the European "BSE Regulation" allow the use of insects and porcine-based meals in poultry farming, providing novel, sustainable substitutes for vegetable fodder. While the technological and nutritional properties of novel feeds containing processed animal proteins are widely recognized, far less is known about consumers' acceptance of meat produced by animals fed on animal-based meals. In the present research, a best-worst survey was applied to estimate consumers' preferences for chicken fed on plants, insects, or porcine-based meals using a sample of 205 Italian consumers. Furthermore, product price, type of farming, and "Free-from" labeling were considered in the analysis to evaluate the relative importance of feed ingredients compared to other important attributes of meats. The results show that the most relevant attributes are type of farming and "Free-from" claims, while type of feed represents the third attribute in order of importance. Notably, both insect and porcine flour are considered as negative characteristics of the product, suggesting that mandatory labeling signaling the use of these feeds would negatively impact on the value of chicken meat.

Stakeholder Beliefs about Alternative Proteins: A Systematic Review.

In recent years, a great deal of research has been conducted on consumers' attitudes and beliefs in favor and against alternative proteins (AP). By contrast, a much more limited research effort has been devoted to understanding stakeholders' point of view. The current work provides a first systematic review of the existing literature on stakeholders' beliefs towards alternative protein sources. Moreover, a secondary content analysis was carried out on the selected studies, providing an overview of the major themes emerging from the existing literature in relation to utilitarian, normative, and control beliefs that stakeholders hold towards AP. Results showed that stakeholders' beliefs are very different from those that emerged from previous research on consumers' views. Overall, stakeholders appear much more aware, compared to consumers, of the implications of using alternative proteins in relation to the main pillars of sustainability (economic, environmental, social). Stakeholders' beliefs were grouped into 13 categories, such as "economics", "consumers", and "rules". With respect to future scenarios, they attribute an important role to political institutions, with respect to both economic and communication aspects, which they consider crucial to overcome persistent consumer skepticism.

The future is crawling: Evaluating the potential of insects for food and feed security.

Current estimations showed that the number of people affected by hunger doubled in the last two years, reaching 9.8% of the global population. According to FAO, in order to satisfy the demand for food in the next few years, it will be necessary to double food production. Moreover, the call for a change in dietary patterns has been raised, showing how the food sector is responsible of 1/3 of climate change where meat-based diets or overconsumption of meat play an important role in the negative environmental impact. Consequently, there is a growing concern in how to achieve the goal of increasing food productions without exploiting environmental resources and to explore the production and use of alternative resources, such as insects. Insects are gaining interests both as food and feed not only to reduce the environmental costs in feed production for common livestock, but also to reduce farmers' dependence on traditional protein sources. In this work we aimed to provide an overview of the state-of-the-art upon insect studies, highlighting the most important results obtained from both an industrial and market perspective. The legislative framework concerning edible insects as food and feed is also analyzed, with the final purpose to highlight recent reforms, relevant case-law as well as unsolved regulatory challenges. From a normative perspective, regulatory efforts are still required to fully take advantage of the potentialities of insects-industry. From a consumer point of view, consumers' willingness to pay a premium is going to be a key issue for economic sustainability of the insect farming chain. To meet the food and feed security challenges, insects will have to be considered all-around, including applications in the food, feed, and other sectors. We believe that this review is an important contribution to the field of food science and will be of interest to researchers, food industry professionals, and policymakers in order to prioritize research questions and help communicate scientific knowledge to a broader audience.

The Interaction between Message Sensation Value and Food Neophobia in Communication about Insect-Based Foods: An Experiment with Italian Consumers.

Currently, insects are considered as a promising alternative protein source due to their nutritional content and their environmental sustainability. Notwithstanding this, generally consumers show reluctance towards the introduction of edible insects into their diet, mostly influenced by food neophobia. Persuasive communication strategies (e.g., informational vs. emotional appeals) have been a major topic in consumer behavior research. Scholars often refer to the construct of message sensation value (MSV), which is defined as the intensity of audio, visual, and content features of a message that elicit sensory, affective, and arousal responses. In this work, a computer-based experiment (N = 148) was conducted to investigate the effectiveness of messages based on different levels of MSV in promoting the intention to eat insect-based foods, and interactions between MSV and food neophobia. Results indicate that, MSV, food neophobia, and their interaction significantly affect the willingness to consume insect-based food products with or without visible insects, highlighting novel pathways for segmenting consumers, in order to strengthen the communication effects.

Intraoperative dexamethasone intravitreal implant in diabetic macular edema patients undergoing phacoemulsification: The CataDex study.

PURPOSE: To assess the impact of preoperative intravitreal dexamethasone implant (DexI) on functional and anatomic outcomes in patients with diabetic macular edema (DME) who underwent phacoemulsification cataract surgery. METHODS: Prospective and non-comparative study conducted on consecutive DME patients undergoing cataract surgery. DexI was administered 15 days before surgery and in a pro re nata regime after surgery. Main outcome measures were mean change in central retinal thickness (CRT), central subfield thickness (CST), total macular volume (TMV), and central subfield volume (CSV) from baseline to month-12. Secondary outcome was mean change in best corrected visual acuity (BCVA). RESULTS: Forty eyes were included in the study. CRT significantly decreased from 410.4 ± 64.8 µm at baseline to 303.2 ± 24.3 µm at month-12, p < 0.0001. Similarly, CST was significantly reduced from 436.4 ± 120.4 µm at baseline to 322.9 ± 54.2 µm at month-12, p < 0.0001. Total macular volume and CSV were significantly reduced from 9.95 ± 1.68 mm3 and 0.38 ± 0.11 mm3 at baseline to 8.49 ± 0.83 mm3 and 0.31 ± 0.05 mm3 at month-12, respectively (p < 0.0001 each, respectively). BCVA significantly improved from 0.26 ± 0.17 Snellen equivalent at baseline to 0.65 ± 0.19 at month-12, p < 0.0001. Mean DexI administered during the study were 2.0 ± 0.3. Neither DME subtype nor previous treatment status had any effect on functional or anatomic outcomes. Regarding safety, one (2.5%) eye developed ocular hypertension, which was successfully controlled with topical hypotensive treatment. CONCLUSIONS: DexI was and effective and safe strategy for managing DME in diabetic patients undergoing uneventful cataract surgery.

Edible Insects and Global Food Security.

Perceived Risk of Insect-Based Foods: An Assessment of the Entomophagy Attitude Questionnaire Predictive Validity.

Insects are a promising alternative protein source and their possible integration in the human diet has been extensively studied, also with reference to the degree of consumer acceptability and the main factors determining reluctance among Western consumers. Several studies have also proposed the use of protein meals derived from insects in animal feed as a possible way to promote the development of the insect chain. Consumer attitudes, perceived risks, and intention to eat insect-based foods have been extensively researched, yet the relationships between those factors are still unclear. On a sample of 202 Italian consumers, the present research used the Entomophagy Attitude Questionnaire (EAQ) to analyse the degree of acceptability of insects as food and meat obtained from animals raised on insect-based feeds with a specific focus on the role of attitudes and perceived risk. The research also evaluated the differences in acceptability between different types of animals fed with insects. The results show that the intention to engage in entomophagy is significantly correlated with all three of the EAQ's subscales, as well as with perceived risk. However, the effect of perceived risk does not significantly improve the predictive validity of EAQ with respect to the intention to eat insect-based food. The results also show that the degree of acceptability for different insect meal-reared animals changes among consumers: beef and pork are characterized by a lower degree of acceptability, while poultry and fish are more accepted by consumers.

The Effect of Verbal and Iconic Messages in the Promotion of High-Quality Mountain Cheese: A Non-Hypothetical BDM Approach.

To ensure the sustainable development of mountain livestock farming, the adequate remuneration of high-quality dairy products is fundamental. In this sense, communication strategies aimed at promoting mountain products and ensure better positioning and higher market prices are fundamental. The present research seeks to expand the literature regarding consumers' willingness to pay for mountain foods by using an online real auction experiment aimed at evaluating the premium price that consumers are willing to pay for summer over winter mountain cheese, depending on the information provided concerning the taste anticipation or animal welfare. The results showed an overall small premium price given to the higher quality summer cheese; this could be, partially, due to a generally low degree of consumer knowledge about mountain dairy farming. With reference to communication strategies, the results provide evidence about the effectiveness of the rational messages founded upon sensorial characteristics and the anticipated taste of cheese. In addition, this study explored that adding a logo had no main effect on the price premium participants were willing to pay. This may be due to the fact that logos and claims, having a lower information content, are more indicated to lead the choice of consumers with a higher level of awareness. In the conclusion section, policy and agribusiness implications of the findings are provided.

New Hope for a "Cursed" Crop? Understanding Stakeholder Attitudes to Plant Molecular Farming With Modified Tobacco in Europe.

Plant molecular farming (PMF) with tobacco could provide a sustainable and cheap platform for the production of high-value proteins for medical use. It could also offer European tobacco farmers an alternative, healthful end use for their crop. New plant breeding techniques (NPBTs) offer a means of quickly and precisely optimizing molecular farming platforms for this purpose. However, there has been little empirical research focussing on the barriers and facilitators of these technologies in the agricultural sphere. Here, we explore key stakeholder perceptions toward this combination of technologies, exploring their understanding of risk and opportunity. We interviewed N = 24 key stakeholders - tobacco farmers, agronomists, policymakers, and researchers - in three tobacco-growing areas of Spain and Italy. Our findings demonstrate these stakeholders have a favorable attitude toward PMF with tobacco due to its beneficial medical purpose and the opportunity it provides farmers to continue growing tobacco in a declining European market. Tobacco producers also reported favorable views toward NPBTs, though for some this was contingent on their use for non-food crops like tobacco. Most stakeholders' concerns are economic in nature, such as potential profitability and demands for new agronomic practices or infrastructure. Tobacco producer associations were thought to be important facilitators for future PMF scale-up. The attitude toward these technologies by smoking tobacco companies is, however, unknown and constitutes a potential risk to the development of PMF.

Assessing the Role of Food Related Lifestyle in Predicting Intention towards Edible Insects.

Although recent literature has shown that switching to an insect-based diet could provide several relevant advantages-from a nutritional, environmental, economic and ecological point of view-the potential growth of insects as everyday food is still unclear. Despite a growing literature on consumer acceptance and product preference for insect-based food, a segmentation of this future and possible market has never been proposed. Therefore, in the present paper, a market segmentation based on the Food Related Lifestyle Scale (FRLS), was performed in order to predict consumers' willingness to eat (WTE) edible insects. Moreover, the role of perceived behavioural control is taken into account. Results shows that the novelty and benefits of insect consumption have generated much interest in edible insects amongst consumers belonging to the Rational cluster, who showed the highest intention to introduce insects in their diet, thus confirming the presence of a niche of "early adopters". In addition, perceived behavioural control was the major driver of intention. Implications for attempts to encourage people to incorporate insect-based foods into their diet are discussed, with special reference to the role of marketing campaigns.

The Potential Role of Insects as Feed: A Multi-Perspective Review.

Recently, insects have received increased attention as an important source of sustainable raw materials for animal feed, especially in fish, poultry, and swine. In particular, the most promising species are represented by the black soldier fly (Hermetia illucens, HI), the yellow mealworm (Tenebrio molitor, TM), and the common house fly (Musca domestica, MD). Although rapid development is expected, insects remain underutilized in the animal feed industry mainly due to technical, financial, and regulatory barriers. In addition, few works have analyzed consumer and stakeholder points of view towards the use of insects as animal feed. In this article, we summarize the main findings of this body of research and provide a discussion of consumer studies regarding the consumption of animals fed with insects. Our review suggests that consumer acceptance will not be a barrier towards the development of this novel protein industry. Furthermore, we conclude that it will be of interest to understand whether the use of this more sustainable feed source might increase consumer willingness to pay for animal products fed with insects and whether the overall acceptability, from a sensory point of view, will be perceived better than conventional products. Finally, the main challenges of the feed farming industry are addressed.
