Background The work experience of seafarers differs significantly from other land-based occupations due to several factors, particularly remoteness and the restricted work environment. This study seeks to examine the impact of burnout and health impairment in the maritime industry, using the Job Demand-Resources theory as a framework. Methods To investigate these phenomena, an online questionnaire was sent to 629 Italian seafarers and we conducted analysis on a valid sample of 239 respondents (94.6% men, Mage = 39.44, SD = 12.8). We tested a mediated Structural Equation Model (SEM) aimed at predicting negative health outcomes. Results The results show that burnout plays a mediating role between job demands (such as workload and cognitive strain) and health impairment (such as sleep quality and physical well-being) (Total Indirect Effect = 0.443, p < .0001) as well as between job resources (such as social support and transformational leadership) and health impairment (Total Indirect Effect = -0.249, p < .0001). Furthermore, the findings highlight the direct influence of occupational resources on seafarers’ health. Conclusions The discussion highlights the urgent need for more research in the field of organisational psychology in the maritime industry and the discrepancies between these findings, which are consistent with the existing maritime literature, and other studies that do not include seafarers in their sample groups.

Despite their genetic diversity, metastatic cells converge on similar physical constraints during tumor progression. At the nanoscale, these forces can induce substantial molecular deformations, altering the structure and behavior of cancer cells. To address the challenges of osteosarcoma (OS), a highly aggressive cancer, we explored the mechanobiology of OS cells, in vitro. Using uniaxial-stretching technology, we examined the biophysical modulation of metastatic traits in SAOS-2, U-2 OS, and non-tumorigenic hFOB cells. Changes in cell morphology were quantified using confocal and fluorescence microscopy. To elucidate the molecular mechanisms that translate biomechanical alterations into biochemical responses, we employed Western blotting, real-time quantitative RT-PCR, reactive oxygen species ROS assay, and the mechanosensitive channel blocker Grammostola MechanoToxin4 (GsMTx-4). Our study reveals that mechanical stimulation uniquely affects OS cells, increasing nuclear size and altering the N/C ratio. We found that mechanosensitive (MS) channels are activated, leading to ROS accumulation, Src protein modulation, and histone H3 acetylation. These changes influence OS cell motility and adhesion but not proliferation. Importantly, mechanical preconditioning differentially impacts doxorubicin resistance, correlating with the Src-H3 acetylation axis. This study underscores the critical role of MS channels in OS cells and highlights the importance of mechanobiology in identifying molecular pathways that traditional biochemical approaches may not reveal. Notably, the GsMTx-4 venom peptide effectively countered mechanically induced responses, particularly by inhibiting OS cell migration, without harming healthy cells. Thus, suggesting its potential as a promising therapeutic agent for targeting osteosarcoma metastasis

Given the importance of social–emotional skills in fostering highly prosocial behaviors and the increasing frequency by which relationships are established and maintained in cyberspace, several studies have been conducted focusing on the role of social-emotional skills developed in the online environment. However, the instruments developed to date have mainly considered “face-to-face” interactions, without considering the unique features of the virtual environment. The purpose of the present study was to validate the Italian translation of the Socio-Emotional e-Competencies Questionnaire. This instrument has been constructed to assess the knowledge, skills, and attitudes necessary to understand and manage emotions in the online environment for fostering positive relationships (e-competencies (e-COM)). The final sample consisted of 1096 adults (53.0% men) aged between 18 and 73 years. Factor analyses confirmed the original five-factor structure, which showed excellent fit indices (i.e., root mean square error of approximation (RMSEA), Tucker–Lewis index (TLI), and comparative fit index (CFI)). Correlation analyses with other instruments related to social–emotional competence (i.e., E-motions Questionnaire, Brief Emotional Intelligence Scale, and Difficulties in Emotion Regulation Scales) confirmed the convergent validity of the scale. Gender differences were also explored, in which women scored higher than men in all dimensions of e-COM except for emotional e-independence. Overall, this study demonstrated that the Italian version of e-COM is a reliable and valid tool for measuring social-emotional competence in a virtual context.

Abstract Perovskite solar cells have rapidly advanced, achieving over 26% power conversion efficiency on the laboratory scale. However, transitioning to large-scale production remains a challenge due to limitations in conventional fabrication methods like spin coating. Here, we introduce an optimized blade coating process for the scalable fabrication of large-area (15 cm × 15 cm) perovskite solar modules with a nickel oxide hole transport layer, performed in ambient air and utilizing a non-toxic solvent system. Self-assembled monolayers between the nickel oxide and perovskite layer improve the uniformity and morphology of the perovskite film. Perovskite solar modules with a 110 cm2 active area achieve a power conversion efficiency of 12.6%. Moreover, encapsulated modules retained 84% of their initial efficiency after 1,000 hours at 85 °C in air (ISOS-T-1). This study demonstrates progress in the large-scale production of perovskite solar cells that combine efficiency with long-term stability.

The relationships among pornography use, sexist ideology and false or stereotypical ideas about rape are controversial. This study specifically examines the associations of problematic pornography use (PPU) with sexism and rape myth acceptance among both male and female participants within the Italian context utilizing a cross-sectional methodology. Based on data from 815 participants collected through an online questionnaire, the study identifies significant gender-based differences, with men typically exhibiting higher scores on sexism, rape myth acceptance, and token resistance beliefs. Correlation analysis revealed that in men, there was a positive relationship between pornography cravings and sexist beliefs but not between pornography cravings and minimizing rape or accusations of lying (rape myth). Women showed significant positive correlations across all problematic pornography use dimensions with sexist ideology, although the relationship with rape myth acceptance varied. These findings underscore the critical need for acknowledging these relationships to enhance strategies for preventing gender-based violence.

BackgroundThe issue of gender-based violence has been a public health problem for years. Considering its systemic nature, the possible consequences at the individual level on the psychological and cognitive wellbeing of victims have been examined. The present research aims to explore the differences in the various types and forms of violence.MethodsA non-probability and convenience sample was used; a total of 83 participants joined the research. Inclusion criteria were minimum age of 18 years, female gender, and knowledge of the Italian language. Two non-parametric One-Way ANOVAs (Kruskal-Wallis) were performed according to the type of violence experienced and the type of self-reported abuse (i.e., no victimization, single victimization, complex victimization).Results and discussionResults showed that victims of violence scored higher overall than non-victims on all subscales of the Depression, Anxiety, Stress Scale. Analyses among the three groups-no violence, single violence, and complex violence-showed no differences in any of the dimensions between those who experienced single and complex violence, while differences emerged between the “no victimization” group and the other groups. The results were discussed in relation to the existing literature on the topic, highlighting the limitations and future applications of the collected data.

Background/Objectives: Internet addiction (IA) and related behaviors, such as Internet Gaming Disorder (IGD) and social media addiction (SMA), have gained increasing research attention. Studies show gender differences, with males more likely to develop gaming-related addictions and females more prone to social media and phubbing behaviors. This study aimed to explore gender differences in Internet addiction and related behaviors in a Spanish sample, with the goal of identifying predictors and gender-specific patterns of IA. Methods: We conducted a cross-sectional study with 585 participants (265 male, 320 female) aged 18 to 35 years (M = 22.11, SD = 3.08). Data were collected using standardized questionnaires to assess IA, IGD, SMA, phubbing, Fear of Missing Out (FoMO), emotional dysregulation, personality traits, and prosociality. Correlation and regression analyses were used to identify gender-specific predictors of IA. Results: Males exhibited significantly higher scores for IA and IGD, while females showed higher scores for SMA and the “phone obsession” dimension of phubbing. No significant gender differences were found in the “communication disturbance” dimension of phubbing or in FoMO. Correlation analyses revealed significant associations between IA and psychological as well as technological variables. Gender-specific predictors of IA included social media engagement and emotional regulation for females, while gaming behaviors and communication patterns were more relevant for males. Conclusions: These findings highlight gender differences in IA, suggesting that tailored interventions should address unique online behaviors and emotional regulation challenges in males and females. Future research should refine gender-specific patterns to develop more effective, targeted prevention and treatment strategies.

IntroductionStudying gambling behavior is a crucial element in reducing the impact of problem gambling. Nevertheless, most current research is carried out in controlled laboratory settings rather than real-life situations, which raises concerns about how applicable the findings are in the broader context. Virtual reality (VR) has proven to be a valuable tool and has been utilized in various experimental scenarios. A limited number of studies have employed VR to investigate gambling behaviors, and few have explored them in an older adolescent context.MethodsThis study examined the behavioral and physiological effects of gambling behavior, including problem gambling, gaming addiction, and risk-taking decision-making in a sample of 36 high-school students aged between 18 to 20 years using an ad-hoc constructed VR scenario designed to simulate a slot-machine platform.ResultsThe behavioral results highlighted that participants reporting more problem gambling were sensitive to near-misses: i.e., they bet more after near-misses than after losses. This result may reflect the false belief that gamblers, after near-misses, are closer to winning. Physiological data showed that participants exhibited heart rate deceleration during the anticipation of the outcome, which has been suggested to represent a marker of feedback anticipation processing and hyposensitivity to losses.DiscussionOverall, this study provides evidence for a new VR tool to assess gambling behaviors and new insights into gambling-related behavioral and physiological factors. Implications for the treatment of problem gambling are discussed.

Physical therapy keeps exploiting more and more the capabilities of the robot of adapting the treatments to patients’ needs. This paper aims at presenting a psychophysiological-aware control strategy for upper limb robot-aided orthopedic rehabilitation. The main features are the capability of i) generating point-to-point trajectories inside an adaptable workspace, ii) providing assistance in guiding the patients’ limbs in accomplishing the assigned task allowing them to freely move with a certain degree of spatial and temporal autonomy and iii) tuning the control parameters according to the patients’ kinematics performance and psychophysiological state. The implemented control strategy is validated in a real clinical setting on eight orthopedic patients undergoing twenty daily robot-aided rehabilitation sessions. The psychophysiological-aware control strategy evidenced a positive impact on the enrolled participants since they are effectively conducted in a calmer condition with respect to the patients who did not receive the psychophysiological adaptation. Moreover, clinical performance indicators suggest that the proposed tailored control strategy improves motor functions.

This review aims to map studies on governmental and institutional decision-making processes in emergencies. The literature reveals various approaches used by governments in managing emergencies. Consequently, this article suggests the need for a systematic literature review to outline how institutional decision-makers operate during emergencies. To achieve this goal, the most widely used databases in psychological research were consulted, with a specific focus on selecting scientific articles. Subsequently, these studies were rigorously assessed for their relevance using a structured literature selection process following the PRISMA 2020 guidelines. At the conclusion of the review process, nine studies were identified, each suggesting different methods by which governments manage emergencies. This diversity arises because emergency decision-making processes must account for numerous variables that change depending on the type of crisis and the specific context. However, several critical aspects have emerged, such as the centrality of pre-disaster planning to improve intervention practices and methods, attention to information gaps that inevitably arise during an emergency, and the importance of streamlining and delegating decision-making to emergency responders in the field to counter the phenomenon of centralized decision-making that often hampers crucial interventions during emergencies.

Background: Tactile stimulation manoeuvres stimulate spontaneous breathing in preterm newborns. The aim of this study is to evaluate the effect of early respiratory physiotherapy on the need for mechanical ventilation during the first week of life in preterm infants with respiratory failure. Methods: This is a monocentric, randomised controlled trial. Preterm infants (gestational age ≤ 30 weeks) not intubated in the delivery room and requiring non-invasive respiratory support at birth were eligible for the study. The intervention group received early respiratory physiotherapy, while the control group received only a daily physiotherapy program (i.e., modifying the infant’s posture in accordance with the patient’s needs). Results: between October 2019 and March 2021, 133 preterm infants were studied, 68 infants in the study group and 65 in routine care. The study group showed a reduction in the need for mechanical ventilation (not statistically significant) and a statistically significant reduction in hemodynamically significant patent ductus arteriosus with respect to the control group (19/68 (28%) vs. 35/65 (54%), respectively, p = 0.03). Conclusions: early respiratory physiotherapy in preterm infants requiring non-invasive respiratory support at birth is safe and has proven to be protective against haemodynamically significant PDA.

Abstract Background Tactile maneuvers stimulating spontaneous respiratory activity in preterm infants are recommended since birth, but data on how and how often these maneuvers are applied in clinical practice are unknown. In the last years, most preterm newborns with respiratory failure are preferentially managed with non-invasive respiratory support and by stimulating spontaneous respiratory activity from the delivery room and in neonatal intensive care unit (NICU), in order to avoid the risks of intubation and prolonged mechanical ventilation. Methods Preterm infants with gestational age

The present study examines the impact of acidic and basic pH on the optical, morphological, and structural characteristics of TiO2 sol–gel thin films that are deposited using the dip-coating technique on glass substrates. All of the samples are polycrystalline and have anatase structures with preference orientation along the (101) direction, according to X-ray diffraction (XRD) and Raman spectroscopy (RS). It is observed that, for both basic and acidic pH values, crystallite size decreases as sol pH rises. All of the films' surfaces were smooth and had a uniform grain distribution, according to atomic force microscopy (AFM). The pH of the sol has an impact on the surface roughness. All films had a higher degree of transparency, according to UV-visible spectroscopy. The refractive index and the direct and indirect band gaps are two essential optical properties of thin films that are significantly influenced by the pH of the deposition medium. Measurements of photoluminescence (PL) showed a strong violet-blue emission band, the intensity of which is highly dependent on the sol's pH. In acidic media, PL decreases with increasing pH. However, in a basic environment, the PL rises sharply as the pH increases from 10 to 11 and then decreases for higher pH values. In particular, compared to the other samples, the emission intensity from the film deposited at a pH value of 10 is noticeably lower and displays unique spectral signatures. Highlights: The effects of acidic and basic pH on the structural, morphological, and optical properties of TiO2 sol–gel thin films were investigated. XRD analyses show that crystallite size decreases with increasing pH in both acidic and basic sols. Optical analysis demonstrates that TiO2 thin films deposited at acidic pH values have greater transparency than those deposited at basic pH values. Photoluminescence measurements revealed a strong correlation between sample emission and pH. The film deposited at pH 10 has significantly lower emission intensity and a distinct spectral signature than the other samples. [ABSTRACT FROM AUTHOR]

Gait impairment is one of the most common disorders of patients with chronic stroke, which hugely affects the ability to carry out the activities of daily living and the quality of life. Recently, traditional rehabilitation techniques have been associated with non-invasive brain stimulation (NIBS) techniques, which enhance brain plasticity, with the aim of promoting recovery in patients with chronic stroke. NIBS effectiveness in improving gait parameters in patients with chronic stroke has been in several studies evaluated. Robotic devices are emerging as promising tools for the treatment of stroke-related disabilities by performing repetitive, intensive, and task-specific treatments and have been proved to be effective for the enhancement of motor recovery in patients with chronic stroke. To date, several studies have examined the combination of NIBS with robotic-assisted gait training, but the effectiveness of this approach is not yet well established. The main purpose of this systematic review is to clarify whether the combination of NIBS and robot-assisted gait training may improve walking function in patients with chronic stroke. Our systematic review was conducted according to the preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines. Studies eligible for review were identified through PubMed/MEDLINE, Embase, Scopus, and PEDro from inception to March 15, 2021, and the outcomes considered were gait assessments. Seven studies were included in the qualitative analysis of this systematic review, with a total population of 186 patients with chronic stroke. All studies specified technical characteristics of robotic devices and NIBS used, with high heterogeneity of protocols. Methodological studies have shown a significantly greater improvement in walking capacity recorded with 6MWT. Finally, research studies have highlighted a positive effect on walking recovery by combination of robot-assisted gait training with non-invasive brain stimulation. Furthermore, future studies should identify the best characteristics of the combined therapeutic protocols.Systematic Review RegistrationCRD42021244869.

High quality MAPbBr3 films were grown by pulsed laser deposition of single-crystalline targets using an on-axis geometry. The gas ambience up to the mbar range and laser fluence of some tenths of Joule per square centimeter yielded single α-phase polycrystalline MAPbBr3 films, as revealed by ex situ XRD analysis. In situ low T studies allowed for the observation of cubic-to-tetragonal and of tetragonal-to-orthorombic phase transitions. Absorption and photoluminescence spectra show characteristic peaks around 2.35 eV. In particular, for thin films, PL measurements at low temperature showed narrow peaks characteristic of high crystalline quality and the absence of relevant defect-related recombination. The present results indicate a route to grow high quality thin films of metal halide perovskites via PLD of single-crystalline targets. [ABSTRACT FROM AUTHOR]

Background: We had previously synthetized a macromolecular prodrug consisting of oxidized Alginate and dopamine (AlgOx-Da) for a potential application in Parkinson disease (PD). Methods: In the present work, we aimed at gaining an insight into the interactions occurring between AlgOx-Da and SH-SY5Y neuronal cell lines in view of further studies oriented towards PD treatment. With the scope of ascertaining changes in the external and internal structure of the cells, multiple methodologies were adopted. Firstly, fluorescently labeled AlgOx-Da conjugate was synthetized in the presence of fluorescein 5(6)-isothiocyanate (FITC), providing FITC-AlgOx-Da, which did not alter SH-SY5Y cell viability according to the sulforhodamine B test. Furthermore, the uptake of FITC-AlgOx-Da by the SH-SY5Y cells was studied using scanning near-field optical microscopy and assessments of cell morphology over time were carried out using atomic force microscopy. Results: Notably, the AFM methodology confirmed that no relevant damage occurred to the neuronal cells. Regarding the effects of DA on the intracellular reactive oxygen species (ROS) production, AlgOx-Da reduced them in comparison to free DA, while AlgOx did almost not influence ROS production. Conclusions: these findings seem promising for designing in vivo studies aiming at administering Oxidized Alginate Dopamine Conjugate for PD treatment.

Background: Stroke in childhood presents a serious rehabilitation challenge since it leads to physical, cognitive and psychosocial disability. The objective of our study was to describe the effectiveness of robot-mediated therapy (RMT) with Gloreha Sinfonia in addition to a conventional treatment in the recovery of the sensory-motor capabilities of the paretic hand and the quality of life in a ten-year-old child after a stroke. Methods: The girl was enrolled to undergo 10 sessions of RMT with Gloreha Sinfonia. She was evaluated with functional scales and with upper limb kinematic analysis at pre-treatment (T0) and at the end of treatment (T1). Outcome measures were Fugl-Meyer Assessment-Upper Extremity (FMA-UE), Visual Analogic Scale (VAS) and Activities and Participation of Daily Life (ADL). In addition, a Force Assessment System based on Virtual Reality games was used to assess the force control and modulation capability at T0 and T1. Results: At the end of treatment, the patient improved in functional scales and in quality of life for greater involvement in some activity of daily living. Force control and modulation capability significantly increased after the treatment. Conclusions: This clinical case highlights possible positive effects of a combined (conventional plus robotic) rehabilitation treatment for the upper limb in pediatric stroke outcomes from both a sensorimotor and functional point of view, also improving the motivational and affective aspects of the patient and of family members. Further studies are needed to validate these results and to identify the most appropriate modalities and doses.

Abstract The Raman spectral features from spinal cord tissue sections of transgenic, ALS model mice and non-transgenic mice were compared using 457 nm excitation line, profiting from the favourable signal intensity obtained in the molecular fingerprint region at this wavelength. Transverse sections from four SOD1G93A mice at 75 days and from two at 90 days after birth were analysed and compared with sections of similarly aged control mice. The spectra acquired within the grey matter of tissue sections from the diseased mice is markedly different from the grey matter signature of healthy mice. In particular, we observe an intensity increase in the spectral windows 450–650 cm−1 and 1050–1200 cm−1, accompanied by an intensity decrease in the lipid contributions at ~1660 cm−1, ~1440 cm−1 and ~1300 cm−1. Axons demyelination, loss of lipid structural order and the proliferation and aggregation of branched proteoglycans are related to the observed spectral modifications. Furthermore, the grey and white matter components of the spinal cord sections could also be spectrally distinguished, based on the relative intensity of characteristic lipid and protein bands. Raman spectra acquired from the white matter regions of the SOD1G93A mice closely resembles those from control mice.
