- Abstract
An emerging body of research has evidenced the negative influence of using and being exposed to social networking sites (SNSs) on body image. Furthermore, it has been postulated that SNS use might be related with onset and persistence of eating disorders (EDs) psychopathology. The aim of the present study is to evaluate the complex interplay between problematic Instagram use (PIU) (conceptualized as a potential behavioral addiction comprising withdrawal, conflict, tolerance, salience, mood modification and relapse) and ED psychopathology, by means of an explanatory structural equation model. We hypothesized that PIU would be associated with ED symptoms through the mediating role of appearance comparison, individual psychological investment in physical appearance, and body uneasiness. A sample of 386 young female participants (M
age = 26.04 ± 6.73) was recruited, of which 152 had received a diagnosis of ED. ED patients used Instagram more than the control group and showed higher levels of PIU. Results from structural equation modeling (fit indices: χ2 = 44.54, df = 19, p < 0.001; RMSEA = 0.059; CFI = 0.98; SRMR = 0.02) showed that PIU predicted appearance comparison and psychological investment in physical appearance, which in turn predicted body uneasiness. In turn, body uneasiness predicted ED psychopathology and interpersonal difficulties. Our model provides a useful account of how eating disorder symptoms could be triggered and maintained by an addictive use of Instagram., (© 2023. The Author(s).)- Published

- Abstract
Anxiety is a pervasive emotional state where, phenomenologically, subjects often report changes in their experience of time and space. However, a systematic and quantified examination of time and space experience in terms of a self-report scale is still missing which eventually could also be used for clinical differential diagnosis. Based on historical phenomenological literature and patients' subjective reports, we here introduce, in a first step, the Scale for Time and Space Experience of Anxiety (STEA) in a smaller sample of 19 subjects with anxiety disorders and, in a second step, validate its shorter clinical version (cSTEA) in a larger sample of 48 anxiety subjects. The main findings are (i) high convergent and divergent validity of STEA with both Beck Anxiety Inventory (BAI) (r = 0.7325; p < 0.001) and Beck Depression Inventory (BDI) (r = 0.7749; p < 0.0001), as well as with spontaneous mind wandering (MWS) (r = 0.7343; p < 0.001) and deliberate mind wandering (MWD) (r = 0.1152; p > 0.05), (ii) statistical feature selection shows 8 key items for future clinical usage (cSTEA) focusing on the experience of temporal and spatial constriction, (iii) the effects of time and space experience (i.e., for both STEA and cSTEA scores) on the level of anxiety (BAI) are mediated by the degree of spontaneous mind wandering (MWS), (iv) cSTEA allows for differentiating high levels of anxiety from the severity of comorbid depressive symptoms, and (v) significant reduction in the cSTEA scores after a therapeutic intervention (breathing therapy). Together, our study introduces a novel fully quantified and highly valid self-report instrument, the STEA, for measuring time-space experiences in anxiety. Further we develop a shorter clinical version (cSTEA) which allows assessing time space experience in a valid, quick, and simple way for diagnosis, differential diagnosis, and therapeutic monitoring of anxiety., Competing Interests: Declaration of competing interest All authors declared no competing interests for this study.

- Abstract
Intuitive eating (IE) is a non-dieting approach that promotes listening to internal cues of hunger and satiety, rather than adhering to external dietary restrictions aimed at weight loss. However, the role of IE in dieting behaviors related to weight-loss approaches is still unclear. To address this issue, the aim of this study was to compare IE levels between dieting and non-dieting individuals, exploring the relationship between IE and dieting-related psychological and physical factors. A sample of 2059 females was recruited via social media and self-reported questionnaires were administered to measure IE, eating psychopathology, self-efficacy, and quality of life. Individuals with a history of dieting exhibited lower IE levels, a higher BMI, and a greater eating psychopathology, as well as a reduced self-efficacy and quality of life, compared to non-dieters. IE showed a protective effect against dieting behaviors, with higher IE levels being associated with a lower likelihood of dieting. Additionally, higher BMI and eating psychopathology were predictors of dieting. Promoting IE could represent a relevant clinical target strategy to address disordered eating and enhance overall well-being, underscoring the need for interventions that foster a healthier relationship with food and bodily internal sensations.

- Abstract
Purpose: Individuals with anorexia nervosa (AN) and bulimia nervosa (BN) frequently exhibit Non-Suicidal Self-Injury (NSSI), yet their co-occurrence is still unclear. To address this issue, the aim of this study was to elucidate the role of impairments in interoception in explaining the NSSI phenomenon in AN and BN, providing an explanatory model that considers distal (insecure attachment/IA and traumatic childhood experiences/TCEs) and proximal (dissociation and emotional dysregulation) risk factors for NSSI., Method: 130 patients with AN and BN were enrolled and administered self-report questionnaires to assess the intensity of NSSI behaviors, interoceptive deficits, IA, TCEs, emotional dysregulation and dissociative symptoms., Results: Results from structural equation modeling revealed that impairments in interoception acted as crucial mediators between early negative relational experiences and factors that contribute to NSSI in AN and BN, particularly emotional dysregulation and dissociation. Precisely, both aspects of IA (anxiety and avoidance) and various forms of TCEs significantly exacerbated interoceptive deficits, which in turn are associated to the emergence of NSSI behaviors through the increase in levels of dissociation and emotional dysregulation., Conclusions: The proposed model provided a novel explanation of the occurrence of NSSIs in patients with AN and BN by accounting for the significance of interoception., Level of Evidence: Level V-Cross-sectional observational study., (© 2024.

- Abstract
Purpose: Anorexia nervosa (AN) is characterized by a diminished capacity in perceiving the physiological correlates of interoceptive sensations, namely bodily self-consciousness. Given the neural division of self-processing into interoceptive-, exteroceptive- and mental-self, we hypothesize neural deficits in the interoceptive-processing regions in AN., Methods: To prove this, we reviewed resting state (rs), task and rest-task studies in AN literature., Results: Neuronal data demonstrate the following in AN: (i) decreased rs-functional connectivity (rsFC) of subcortical-cortical midline structures (SCMS); (ii) reduced rsFC between medial (default-mode network/DMN and salience network/SN) and lateral (executive-control network/ECN) cortical regions; (iii) decreased rsFC in mainly the regions of the interoceptive-self; (iv) altered activity with overall increased activity in response to sensory/body image stimuli, especially in the regions of the interoceptive-self; (v) lack of a clear task-related distinction between own's and others' body image., Conclusion: These data may indicate that rs-hypoconnectivity between SCMS, as neural correlate of a reduced intero-exteroceptive integration resulting in self-objectification, might be linked to overall increased activity in interoceptive regions during sensory/body image stimuli in AN, engendering an "anxious bodily self.", Level of Evidence: I: Systematic review., (© 2022.

- Abstract
The deep southern Adriatic Sea is home of widespread cold-water coral colonization (Madrepora oculata, Lophelia pertusa, Desmophyllum dianthus) which is at present limited by large to its western (Apulian) margin and central part, including the Bari Canyon system. On the contrary, the eastern side is today almost deprived of significant coral growth and this asymmetrical distribution has been ascribed primarily to the action of the North Adriatic Dense Water (NAdDW) that impinges more efficiently on the Apulian margin. The collection of subfossil specimens of M. oculata, L. pertusa and D. dianthus provided the very first dates for cold-water coral colonization along the eastern margin. Once combined with known distribution of live cold-water corals and fossil occurrences in the southern Adriatic Sea, uranium-series dating provides evidence of (i) coral presence in the southeastern Adriatic during the Last Glacial Maximum (LGM), followed by (ii) a time of basin-wide colonization after the post-Last Glacial Maximum and encompassing the Younger Dryas, (iii) another time of undocumented coral presence with the onset of Sapropel S1. Perturbations of the thermohaline circulation in this sector of the Mediterranean basin might have governed the presence and demise of the resident cold-water coral populations interfering with strength and trajectories of main water masses. It is hypothesized that the achievement of the current asymmetrical distribution did occur since the end of S1 protracting to present time. The post-S1 reorganization likely brought to the current hydrological situation where the influence of NAdDW prevails in the western side and corals are doing at best on its trajectory. The scarcity of datable material makes the proposed scenario open to debate and in need of further supporting evidence.

- Abstract
In this work, we present preliminary results of the first application in the Mediterranean Sea of a hyperspectral camera, a device commonly used for satellite or airborne remote sensing, adapted for the underwater environment. The spectral analysis was carried out on hyperspectral images acquired in two different environmental settings in the southern Adriatic Sea. This new technology shows high potentialities of application for benthic habitat mapping and monitoring.

- Abstract
Purpose: Disordered eating and body image concerns are increasingly common among adolescents, possibly representing the underpinning of eating disorders (EDs). This cross-sectional observational study aimed at investigating the relationship between various patterns of sports involvement or inactivity, and the abovementioned psychopathological dimensions., Methods: All adolescents attending their 3rd-5th Italian grade in a single high school reported their sociodemographic and anthropometric data, their weekly sports involvement, and filled the Eating Disorders Examination Questionnaire 6.0 (EDE-Q), the Body Uneasiness Test, and the Muscle Dysmorphia Disorder Inventory (for boys). Comparisons were performed considering sex, weekly hours of activity, and different sports type (none, individual, or team sports)., Results: Of 744 enrolled students, 522 (70.2%) completed the survey. Girls showed higher underweight rates, preference for inactivity or individual sports, and higher psychometric scores compared to boys. Among girls, no differences were found based on time spent exercising or sports type. Inactive boys displayed worse weight- and shape-based psychopathology, higher body uneasiness, and higher appearance intolerance compared to those who devoted more time to exercise. Among boys, individual and team sports were associated with lower EDE-Q scores compared to inactivity, whereas body uneasiness and appearance intolerance were lower only in team sports., Conclusions: The study confirms the presence of remarkable sex differences in eating and body concerns of adolescents. Among boys, sports involvement is tied to lower ED psychopathology, and preference for team sports may be associated with reduced concerns. Wider longitudinal studies on will clarify the direction and specificity of these findings., Level of Evidence: Level V-Cross-sectional observational study., (© 2023. The Author(s).)

- Abstract
Social anxiety disorder (SAD) is characterized by social anxiety/fear, self-attention, and interoception. Functional magnetic resonance imaging studies demonstrate increased activity during symptom-sensitive tasks in regions of the default-mode network (DMN), amygdala (AMG), and salience network (SN). What is the source of this task-unspecific symptom-sensitive hyperactivity in DMN? We address this question by probing SAD resting state (rs) changes in DMN including their relation to other regions as possible source of task-unspecific hyperactivity in the same regions. Our findings show the following: (1) rs-hypoconnectivity within-DMN regions; (2) rs-hyperconnectivity between DMN and AMG/SN; (3) task-evoked hyperactivity in the abnormal rs-regions of DMN and AMG/SN during different symptom-sensitive tasks; (4) negative relationship of rest and task changes in especially anterior DMN regions as their rs-hypoconnectivity is accompanied by task-unspecific hyperactivity; (5) abnormal top-down/bottom-up modulation between anterior DMN regions and AMG during rest and task. Findings demonstrate that rs-hypoconnectivity among DMN regions is negatively related to task-unspecific hyperactivity in DMN and AMG/SN. We propose a model of "Topography of the Anxious Self" in SAD (TAS-SAD). Abnormal DMN-AMG/SN topography during rest, as trait feature of an "unstable social self", is abnormally aggravated during SAD-sensitive situations resulting in task-related hyperactivity in the same regions with an "anxious self" as state feature.

- Abstract
The Marine Strategy Framework Directive (MSFD), introduced in June 2008, was adopted to achieve a Good Environmental Status (GES) in the EU's marine waters and to protect resources of socio-economic interest. The MSFD exerts to the marine area over which a Member State exercises jurisdictional rights in accordance with the United Nations Convention on the Law of the Sea (UNCLOS), including the deep-sea waters, seafloor and sub-seafloor of the Exclusive Economic Zones (EEZ). However, currently the MSFD focuses on coastal habitats and the shallow-water seafloor to the detriment of the deeper habitats. Despite the huge dimension of the deep sea (below 200 m of depth) covering more than 65% of the Earth's surface and including >95% of the global biosphere, the relevance of the dark portion of the seas and oceans is still almost completely neglected. Given the important bi-directional links between shallow and deep ecosystems, there is a clear need for extending the implementation of the MSFD into the deep sea, to define a sound ecosystem-based approach for the management and protection of deep-sea ecosystems and attain GES. We assembled data on drivers, anthropogenic pressures and impacts concerning the MSFD descriptors pertaining to the Mediterranean deep sea. We list deep-sea monitoring activities and the main sources providing benchmark conditions, and discuss knowledge and geographic coverage gaps. MSFD descriptors apply to the deep sea as to coastal waters, and ought to be monitored contemporaneously. We provide recommendations for guidelines for future deep-sea monitoring in the Mediterranean Sea.

deep rhodolith beds,rhodolith development, nucleus, monitoring ,GEO/01 - PALEONTOLOGIA E PALEOECOLOGIA - Abstract
During the research for identification and monitoring of priority marine benthic habitats, an extraordinary rhodolith bed has been discovered at the Egadi Islands, Sicily, Southern Italy. Its exploration has been conducted, onboard the R/V Minerva Uno in July 2016, using a Multibeam Echosounder coupling with observations by ROV dive (video recording of > 1 km of seafloor) and direct sampling by Van Veen grab (70 l, 3 samples). Remote data and ROV inspections have been processed in order to produce a precise cartography of the habitat extension. ROV video and grab samples have been used to describe i) main sedimentary and biological features of the bed, ii) rhodolith morphotypes, iii) dominant algal species and iv) associated biodiversity. The rhodolith bed extends up to 7 km2 southeast of Marettimo Island and extended toward Favignana Island, at depth ranging between 90 and 100 m. Living rhodoliths cover up to 95% of the explored area. Patches of mobile biogenic sediments, mainly sand and gravel, are scattered within the living bed. Sedimentary structures, like megaripples and bioturbations by Spatangus sp. and Cydaris sp. are commonly visible on ROV video frames. Pralines are the dominant rhodolith morphotype, with medium size of L axis of 1.1 cm (max 3.4 cm), and an ellipsoidal to discoidal shape. The nucleus is formed by terrigenous clasts, or rarely, by biogenic components. Living calcareous algae are Phymatolithon lenormandii (Areschoug) Adey 1966, Lithothamnion spp. and L. valens Foslie 1909. The algal association at the nucleus of rhodoliths is characterized by different species, namely Lithophylloidea and Titanoderma spp.. The latter are representative of a shallower setting, perhaps the one occurring when the bed started to develop. Radiocarbon dating of the nucleus are still in progress, aimed at verifying this hypothesis and place the process of rhodolith formation in the correct temporal frame.

Coralline disease, Egadi Islands, deep rhodolith beds ,GEO/01 - PALEONTOLOGIA E PALEOECOLOGIA - Abstract
Coralline algae are among the most important marine calcifiers on a global scale, and are sensitive to rising temperatures and ocean acidification from the ongoing global climate change. Although diseases of coralline algae are known since the nineties in the Pacific Ocean, still few observations and studies are available on this topic. In the Mediterranean, similar events have been reported starting from 2015, in the north-western Mediterranean Sea, within 30 m of water depth. One of the commonest disease is the Coralline White Patch Disease (CWPD), that shows the bleaching of thallus patches due to cell necrosis. The CWPD is temperature-dependent, and it is suggested a relationship with the effects of global climate change. This contribution is aimed at describing CWPD in a rhodolith bed of the Egadi Islands (western Mediterranean). Two sites at a distance of 3 km have been sampled, at 86 and 103 m, by Van Veen grab, 60 l, three replicates each. Living rhodoliths have been selected and analysed for the occurrence of CWPD. A one-way ANOVA has been elaborated to test the difference in percent occurrence of diseased rhodoliths at the two sites. Rhodoliths affected by CWPD ranging in size between 1 and 4 cm are 5% and 5,7% of the total live rhodoliths, with no statistically significant difference between the two sites. At the depth of sampling, the influence of the rising temperature should be negligible, and other factors should be explored to explain the cause of the CWPD.

- Abstract
A new cold-water coral (CWC) province has been identified in the Mediterranean Sea in the Capo Spartivento canyon system offshore the southern coast of Sardinia. The âSardinia cold-water coral provinceâ is characterized in the Nora canyon by a spectacular coral growth dominated by the branching scleractinian Madrepora oculata at a depth of 380â460 m. The general biohermal frame is strengthened by the common occurrence of the solitary scleractinian Desmophyllum dianthus and the occasional presence of Lophelia pertusa. As documented by Remotely Operated Vehicle survey, this area is a hotspot of megafaunal diversity hosting among other also live specimens of the deep oyster Neopycnodonte zibrowii. The new coral province is located between the central Mediterranean CWC provinces (Bari Canyon, Santa Maria di Leuca, South Malta) and the western and northern ones (Melilla, Catalan-Provençal-Ligurian canyons). As for all the best developed CWC situations in the present Mediterranean Sea, the new Sardinian province is clearly influenced by Levantine Intermediate Water which appears to be a main driver for CWC distribution and viability in this basin.

- Abstract
Hyperspectral imagers enable the collection of high-resolution spectral images exploitable for the supervised classification of habitats and objects of interest (OOI). Although this is a well-established technology for the study of subaerial environments, Ecotone AS has developed an underwater hyperspectral imager (UHI) system to explore the properties of the seafloor. The aim of the project is to evaluate the potential of this instrument for mapping and monitoring benthic habitats in shallow and deep-water environments. For the first time, we tested this system at two sites in the Southern Adriatic Sea (Mediterranean Sea): the cold-water coral (CWC) habitat in the Bari Canyon and the Coralligenous habitat off Brindisi. We created a spectral library for each site, considering the different substrates and the main OOI reaching, where possible, the lower taxonomic rank. We applied the spectral angle mapper (SAM) supervised classification to map the areal extent of the Coralligenous and to recognize the major CWC habitat-formers. Despite some technical problems, the first results demonstrate the suitability of the UHI camera for habitat mapping and seabed monitoring, through the achievement of quantifiable and repeatable classifications.

- Abstract
Rhodolith beds are priority marine benthic habitats for the European Community, because of their relevance as biodiversity hotspots and their role in the carbonate budget. The high-Mg calcite calcified thalli promote their preservation through time, resulting in their common occurrence in the fossil record, thus making rhodoliths a significant archive of past environmental and climate changes. The present temperate Mediterranean Sea is home to rhodolith-rich up to rhodolith-dominated habitats which have been targeted over the years for ecological research and management actions. Furthermore, the Mediterranean Basin hosts an important fossil legacy of rhodolith beds that formed under contrasting climatic scenarios since the Neogene. Most examples of Mediterranean rhodolith beds lay within the depth range (30-75 m), while far less is known about deeper occurrences. An outstanding rhodolith bed has been recently identified off the Egadi Archipelago (70-95 m, Central Mediterranean Sea) in the frame of the Italian Marine Strategy Framework Directive project. The rhodolith bed carpets an area >7 km2 between Marettimo and Favignana Islands (Egadi Archipelago), with a cover of live rhodoliths up to 95%. The dominant rhodolith morphotype is pralines, ellipsoidal to discoidal in shape (average size 11 mm, maximum size 31 mm) associated with biogenic gravelly-sand. They present both seafloor bedforms (megaripples and ripples) and frequent bioturbations by epifaunal and semi-infaunal sea urchins. Old algal nodules, biogenic sand/mud, or, less frequently, terrigenous particles serve as nucleus of individual rhodoliths. Living calcareous algae are Lithothamnion valens, L. cf. minervae, Phymatolithon lenormandii, and Lithothamnion spp. The latter characterize also the dead algal association close to the nucleus, with the subordinate presence of Lithophyllum sp. Benthic fauna corresponds to the circalittoral environment, with exclusive species of the Coastal Detritic biocoenosis or

A recent geo-marine survey of the Malta Escarpment revealed for the first time the existence of live cnidarian assemblages at about 300 m depth. These associations have been observed by means of a remotely operated vehicle (ROV) during surveys carried out on the upper part of the Malta Escarpment. The assemblages established on hard bedrock were chiefly composed of the antipatharianLeiopathes glaberrima. The Malta Escarpment is known to have been successfully colonised by deep-water scleractinian assemblages until the last glacial age. However, no living specimens had been observed, and only specimens of dead but relatively freshDendrophyllia cornigerahad been reported. This area of the Mediterranean Sea, which connects the deep Ionian basin to the western Mediterranean, is largely unknown and in clear need of thorough exploration. [ABSTRACT FROM AUTHOR]

- Abstract
The Gulf of Naples is an example of the most beautiful and biodiverse marine regions of the Mediterranean Sea and of the most impacted areas in terms of industrial activities, large contaminated areas, resource exploitation, infrastructures at sea and maritime transportation. We conducted Remotely Operated Vehicle surveys in the Dohrn Canyon in the Tyrrhenian Sea at approximately 12 NM off Naples metropolitan area, and revealed a hotspot of deep-sea benthic biodiversity of sessile fauna at ca. 400 m depth. The hard bottoms are characterized by a high abundance of charismatic species, such as the habitat forming cold-water corals (CWC) Madrepora oculata, Lophelia pertusa, Desmophyllum dianthus in association with the large size bivalves Acesta excavata and Neopycnodonte zibrowii. This CWC-bivalve co-occurrence represents a novel biotope for the Mediterranean Sea, which coexists with the evidence of severe anthropogenic threats, such as illegal dumping and fishery malpractices that were visually documented during the survey. We recommend the adoption of specific protection measures to preserve these unique deep-sea assemblages showing the uncommon co-existence of such a number of deep-sea species in a single habitat.

- Abstract
AbstractAggregations of sea pens are important soft-bottom communities providing a three-dimensional complexity from which several associated species can benefit. The red sea pen Pennatula rubrais one of the Mediterranean coastal field-forming sea pens able to establish dense aggregations on the sandy/muddy bottoms of the infra- and circumlittoral zones. This species was first described at the end of the 17th century, but since then little information has been published about its biology, ecology and biogeography. Even less is known about its behaviour, its reactions after disturbance and its possible escape strategies. Several species of pennatulaceans can withdraw partially or completely into the sediment, usually in a fast (i.e. a few seconds) process of polyp closure and expulsion of part of the water contained within the colony. The present study reports and discusses the withdrawal behaviour of P. rubraafter disturbance. This behaviour has never been documented before in this species. It proved to be a slow process requiring between 210 and 340 seconds (3 min 30 sec to 5 min 40 sec) for the complete withdrawal. Moreover, a soft bioluminescence was observed in two undisturbed colonies in the study area, while two other colonies were found to be out of the sediment, inflating themselves with seawater and getting carried by currents as a sort of dispersal behaviour.

- Abstract
Pockmarks are crater-like depression on the seafloor associated with hydrocarbon ascent through muddy sediments in continental shelves around the world. In this study, we examine the diversity and distribution of benthic microbial communities at shallow-water pockmarks adjacent to the Middle Adriatic Ridge. We integrate microbial diversity data with characterization of local hydrocarbons concentrations and sediment geochemistry. Our results suggest these pockmarks are enriched in sedimentary hydrocarbons, and host a microbial community dominated by Bacteria, even in deeper sediment layers. Pockmark sediments showed higher prokaryotic abundance and biomass than surrounding sediments, potentially due to the increased availability of organic matter and higher concentrations of hydrocarbons linked to pockmark activity. Prokaryotic diversity analyses showed that the microbial communities of these shallow-water pockmarks are unique, and comprised phylotypes associated with the cycling of sulfur and nitrate compounds, as well as numerous know hydrocarbon degraders. Altogether, this study suggests that shallow-water pockmark habitats enhance the diversity of the benthic prokaryotic biosphere by providing specialized environmental niches.

- Abstract
Multibeam echosounders provide ideal data for the semi-automated seabed feature extraction and accurate morphometric measurements. In this study, bathymetric and raw backscatter data were initially used to manually delimit the reef morphologies found in an insular semi-enclosed gulf in the northern Aegean Sea (Gera Gulf, Lesvos Island, Greece). The complexity of this environment makes it an ideal area to "crash test" (test to the limit) and compare the results of the delineation methods. A large number of (more than 7000) small but prominent reefs were detected, which made manual mapping extremely time-consuming. Three semi-automated tools were also employed to map the reefs: the Benthic Terrain Modeler (BTM), Confined Morphologies Mapping (CoMMa), and eCognition Multiresolution Segmentation. BTM did not function properly with irregular reef footprints, but by modifying both the bathymetry and slope, the outcome was improved, producing accurate results that appeared to exceed the accuracy of manual mapping. CoMMa, a new GIS morphometric toolbox, was a "one-stop shop" that, besides generating satisfactory reef delineation results (i.e., detecting the same total reef area as the manual method), was also used to extract the morphometric characteristics of the polygons resulting from all the methods. Lastly, the Multiresolution Segmentation also gave satisfactory results with the highest precision. To compare the final maps with the distribution of the reefs, mapcurves were created to estimate the goodness-of-fit (GOF) with the Precision, Recall, and F1 Scores producing values higher than 0.78, suggesting a good detection accuracy for the semi-automated methods. The analysis reveals that the semi-automated methods provided more efficient results in comparison with the time-consuming manual mapping. Overall, for this case study, the modification of the bathymetry and slope enabled the results' accuracy to be further enhanced. This study asserts that the use of semi-automated mapping is an effective method for delineating the geomorphometry of intricate relief and serves as a powerful tool for habitat mapping and decision-making.

The incidence of eating disorders in children, mainly of anorexia nervosa, is dramatically increased in the last years. A timely identification of the disease is associated with higher rates of recovery. Aim of the work is to underline signs and symptoms that can be used to an early detection of anorexia nervosa in the pediatric age. A scoping review has been conducted by The Italian Pediatric Society Adolescent Study Group according to the PRISMA Extension guidelines for Scoping Reviews, using the search term "anorexia nervosa" and the following filters "review", "systematic review", "age 0–18", "last 4 years". The strategy search produced 657 studies, of which 52 were included in this revision. Screening and red flags were discussed in 23 reports, genetics in 12, neurological pathways in 11, environmental factors in 10, and gut microbiota in 7. An accurate physiological and pathological anamnesis, physical and psychological examination, including the body perception, should be taken in account as well as the presence of co-morbidities, including chronic functional abdominal pain and autoimmune/autoinflammatory diseases. Evidence suggests the role of familiar predisposition as well as of neurological morphology and pathway in anorexia nervosa development. Gut microbiota has also been included among possible risk factor for developing anorexia nervosa due to a complex direct and indirect interactions between gut and brain. The Italian Pediatric Society Adolescent Study Group suggests performing an accurate familial and personal anamnesis, including psychological evaluation as well as a physical exam including auxological parameters as a screening tool during pediatric checks to better explore the risk of developing anorexia nervosa.

Introduction: Body uneasiness is a central facet of body image disturbances observed in individuals with eating disorders (EDs). This study aimed to address gaps in understanding body uneasiness in severe and enduring eating disorders (SE-EDs) and explore variations in psychopathology between individuals with different durations of the disorder. We hypothesized that patients with SE-ED might develop habitual behaviors that contribute to ambivalence toward treatment and the persistence of symptoms. Methods: A sample of 360 ED patients was evaluated at the beginning and end of a specialized intensive rehabilitation program. All patients completed the Eating Disorder Examination Questionnaire (EDE-Q) and the Body Uneasiness Test (BUT). They were divided into two groups: SE-ED (> 7 years) and acute (aED, < 3 years) duration. Results: Compulsive self-monitoring showed a significant change between the start and end of treatment, differing between groups, with a larger change observed in SE-ED (p < 0.048). In SE-ED, it was associated with lower chances of dropout (p = 0.044), opposite to aED (p = 0.009). Treatment responses were primarily related to eating psychopathology, further highlighting differences between the two groups. Conclusions: This study underscores the possible presence of a habit in SE-ED and the importance of tailoring interventions to address unique needs based on the duration of the disorder. Furthermore, it highlights the need for further research to improve treatment outcomes in SE-EDs. Plain English Summary: This study looked at how people with severe and enduring eating disorders (SE-EDs) feel about their bodies and how it affects their treatment. We studied 360 people in a special treatment program. We found that people with SE-EDs were more likely to monitor their bodies a lot, and this made them less likely to stop treatment. This was different for people with short-term disorders. The way people felt about eating also affected how well they responded to treatment. This study shows that people with long-lasting eating disorders might have habits that affect their treatment, and we need to think about this when helping them. There is still a lot to learn about how to treat SE-EDs better. [ABSTRACT FROM AUTHOR]

Coralligenous bioconstructions are biogenic calcareous formations developing at low irradiance on littoral rocky cliffs or on the deeper sub-horizontal bottom in the Mediterranean Sea. Unusually shallow coralligenous banks on the sandy coast of Sinuessa (Mondragone City, Gulf of Gaeta, SW Italy) were investigated. Their communities and the surrounding biogenic detritus were characterized. Geophysical and acoustic data revealed the presence of coralligenous banks between 7.5 and 15 m depth, showing constant thickness and sub-horizontal geometry, incised by sub-perpendicular channels. Sediment deposits ranging from silty sands to bioclastic gravel occur in the area. The biogenic detritus of the soft bottom sampled around the coralligenous banks is highly heterogeneous. Through the thanatocoenosis analysis of macrozoobenthos, different biocenoses were detected, among which the coralligenous and photophilic habitats are mainly represented, followed by the well-calibrated fine sands and the relit sands. A total of 16 different species and 10 epimegabenthic morphological groups (MGs) were detected on the coralligenous banks, of which 4 are included in European regulation for threatened species. The density of epimegabenthic organisms has an average of 10.34 ± 5.46 individuals or colonies/100 m
2 . Cladocora caespitosa is the dominant species, with a height of 17 ± 5 cm. This and other structuring species (SS) were larger in size in the sampled sites than in the literature data. Overall, coralligenous had a "medium" health status, with 52% of the individuals or colonies in healthy conditions, compared to 47% with epibiosis phenomena and 1% with entanglement. Longlines were the most common anthropogenic litter, with a density of 2/100 m2 . Ad hoc monitoring programs and conservation measures would be desirable to protect and guarantee the well-being of these sensitive and rare shallow bioconstructions. [ABSTRACT FROM AUTHOR]- Published

Background/Objectives: The discrepancy between the current perceived body image (BI) and beauty ideals leads to dissatisfaction, which is believed to be common among adolescents. This study aimed to investigate the stability in BI perceptions and dissatisfaction during early adolescence. Another aim was to highlight differences in dissatisfaction according to Body Mass Index (BMI) and inconsistencies in weight status perception. Methods: Two hundred and nine participants (mean age at first survey: 11.33 ± 0.38 years) were enrolled in this longitudinal study with three years of follow-up. Data on size and BI perceptions were collected through individual interviews. Stature and weight were directly measured. Results: Findings indicated significant changes over three years in anthropometric traits but not in weight status prevalence or BI perception and dissatisfaction, except for the ideal figure in males and weight control in females. The results also indicated a significant difference in BI perception and dissatisfaction by BMI categories. Self-reported body measurements were found to be unreliable with a weak-to-moderate agreement between self-perceived and actual weight status. Conclusions: BI perception appears quite stable across the three years considered. Dissatisfaction is similar in both genders, although a tendency toward different gender aesthetic ideals is already appreciable in early adolescence. We suggest that the lower frequency of normal-weight adolescents compared with peers in previous studies is attributable to the effects of the recent pandemic. Given the growing dissatisfaction with increasing BMI and misinterpretations of weight status, school actions to promote a healthy lifestyle and positive BI should be undertaken.

The island of Sicily is considered to be among the first occupied by humans in the European Upper Paleolithic. Studies to understand early occupation of the island are mostly concentrated on the northern shores. Our project, Early Occupation of Sicily (EOS), focuses on southeastern Sicily so to address questions regarding dispersal to Mediterranean islands and Late Pleistocene landscapes and environments. Here, we present the initial results of our terrestrial and underwater surveys in combination with archival work and analyses of museum collections. In SE Sicily very few Upper Paleolithic sites have been excavated and analyzed using scientific methods. We have relocated and assessed ~20 caves and rock shelters identified between the 1870s and 1990s, studied museum collections, and collected raw material to reconstruct procurement patterns. To identify new sites, we conducted land and underwater surveys to reconstruct paleo-shorelines and past environments. We have identified three sites, two on land and one partially submerged, that still contain unexplored archaeological sediments, demonstrated in one instance through seismic tomography. This work shows the potential of re-examining minimally studied sites and materials to reconstruct mobility patterns and environmental impact of the first inhabitants of the island.

Eating disorders (EDs), including anorexia nervosa (AN), bulimia nervosa (BN), binge-eating disorder (BED), and pica, are psychobehavioral conditions characterized by abnormal eating behaviors and an excessive preoccupation with weight and body shape. This review examines changes in brain regions and functional connectivity in ED patients over the past decade (2013–2023) using resting-state functional magnetic resonance imaging (rs-fMRI). Key findings highlight alterations in brain networks such as the default mode network (DMN), central executive network (CEN), and emotion regulation network (ERN). In individuals with AN, there is reduced functional connectivity in areas associated with facial information processing and social cognition, alongside increased connectivity in regions linked to sensory stimulation, aesthetic judgment, and social anxiety. Conversely, BED patients show diminished connectivity in the dorsal anterior cingulate cortex within the salience network and increased connectivity in the posterior cingulate cortex and medial prefrontal cortex within the DMN. These findings suggest that rs-fMRI could serve as a valuable biomarker for assessing brain function and predicting treatment outcomes in EDs, paving the way for personalized therapeutic strategies.

- Abstract
The pervasive presence of marine litter represents a significant threat to Mediterranean biogenic reefs, leading to habitat degradation and a negative impact on associated structuring organisms, such as sponges and gorgonians. This communication highlights one of the detrimental effects caused by abandoned or lost fishing gear on colonies of Paramuricea clavata (Risso, 1827) from MPA Asinara Island (Mediterranean Sea). The study is part of the Strong Sea Life project (Survey and Treatment ON Ghost Nets SEA LIFE), aimed at mitigating the effects of abandoned fishing gear and enhance the conservation status of priority habitats of Posidonia oceanica (Linnaeus) Delile, 1813 and coralligenous reefs.

Introduction: Eating disorders are associated with substantial burden for the affected individuals including negative health outcomes and increased mortality. So far, prevention programs for eating disorders have yielded mixed results concerning their efficacy. Therefore, more targeted prevention programs need to be developed. Health literacy has been identified as a potential influencing factor of eating disorders. This study aimed at exploring the relationship between likely cases of eating disorders and health literacy, alongside additional sociodemographic factors. Materials and methods: Two large samples of adults (N = 3,011) and adolescents (N = 1,021) representative of the German-speaking population in Germany were recruited. Likely cases of eating disorders were identified using the SCOFF questionnaire. Health literacy was assessed with the HLS-EU-Q16 questionnaire. Sociodemographic information, including age, gender, social status and level of education, and subjective body image were obtained. χ²-tests of independence were calculated to determine the association between the investigated constructs. Results: Suspected eating disorders were more likely in female than male adolescents but were not related to gender in adults. Rates of suspected eating disorders increased with increasing age in adolescents and decreased with increasing age in adults. While levels of education were unrelated to suspected eating disorders, low social status was associated with higher rates of suspected eating disorders in adults but not adolescents. Inadequate or problematic health literacy and negative body image were associated with higher rates of suspected eating disorders compared to adequate health literacy and more positive body image. Discussion: Likely cases of eating disorders are related to health literacy and body image as well as sociodemographic factors. These constructs should therefore be addressed in future research to improve prevention programs. [ABSTRACT FROM AUTHOR]

The NEREA (Naples Ecological REsearch for Augmented observatories) initiative aims to establish an augmented observatory in the Gulf of Naples (GoN), designed to advance the understanding of marine ecosystems through a holistic approach. Inspired by the Tara Oceans expedition and building on the scientific legacy of the MareChiara Long-Term Ecological Research (LTER-MC) site, NEREA integrates traditional physical, chemical, and biological measurements with state-of-the-art methodologies such as metabarcoding and metagenomics. Here we present the first 10 months of NEREA data, collected from April 2019 to January 2020, encompassing physico-chemical parameters, plankton biodiversity (e.g., microscopy and flow cytometry), prokaryotic and eukaryotic metabarcoding, a prokaryotic gene catalogue, and a collection of 3818 prokaryotic Metagenome-Assembled Genomes (MAGs). NEREA's efforts produce a significant volume of multifaceted data, which enhances our understanding of marine ecosystems and promotes the development of scientific hypotheses and ideas.
