Background: Patients with cystic fibrosis (CF) experience recurrent bacterial pulmonary exacerbations. Management of these infections is increasingly challenging due to decreased antimicrobial susceptibility to beta-lactam antibiotics. The pharmacokinetics of these agents are inadequately characterized in patients with CF., Methods: One hundred fifty-five pediatric and adult participants with CF receiving cefepime (n=82), meropenem (n=42), or piperacillin-tazobactam (n=31) were enrolled. Opportunistic blood samples were obtained during hospitalization. Population PK analysis was conducted using nonlinear mixed-effects modeling. Clinical and demographic characteristics were evaluated as potential covariates. Monte Carlo simulations were performed to evaluate probability of target attainment (PTA) for different dosing regimens., Results: Estimated creatinine clearance, and total or lean body weight, affected the pharmacokinetics of cefepime and meropenem. No covariates were identified for piperacillin and tazobactam. In the cefepime group, a 3-h infusion achieved higher PTA than a 0.5-h infusion for all participants. Estimated breakpoints (the respective minimum inhibitory concentration (MIC) up to which ≥90% of patients are predicted to reach a PK/PD target) were two- to four-fold higher in pediatric participants receiving a 3-h vs. 0.5-h infusion. In the meropenem group, increased creatinine clearance led to reduced PTA. In the piperacillin-tazobactam group, total daily dose and mode of administration were principal drivers of PTA., Conclusions: Standard dosing regimens fail to achieve specific MIC targets in patients with CF. Therefore, clinicians should incorporate local antibiograms and PK models to determine optimal dosing. Further PK optimization to account for interindividual differences could be achieved by real-time beta-lactam therapeutic drug monitoring., (© The Author(s) 2024.

Objective: People's psychological tendencies are attuned to their sociocultural context and culture-specific ways of being, feeling, and thinking are believed to assist individuals in successfully navigating their environment. Supporting this idea, a stronger "fit" with one's cultural environment has often been linked to positive psychological outcomes. The current research expands the cultural, conceptual, and methodological space of cultural fit research by exploring the link between well-being and honor, a central driver of social behavior in the Mediterranean region., Method: Drawing on a multi-national sample from eight countries circum-Mediterranean (N = 2257), we examined the relationship between cultural fit in honor and well-being at the distal level (fit with one's perceived society) using response surface analysis (RSA) and at the proximal level (fit with one's university gender group) using profile analysis., Results: We found positive links between fit and well-being in both distal (for some, but not all, honor facets) and proximal fit analyses (across all honor facets). Furthermore, most fit effects in the RSA were complemented with positive level effects of the predictors, with higher average honor levels predicting higher well-being., Conclusions: Our findings highlight the interplay between individual and environmental factors in honor as well as the important role honor plays in well-being in the Mediterranean region., (© 2022 The Authors.

Gender-based violence is a widespread phenomenon that significantly impacts many women around the world. Among the different forms that it might take, image-based sexual abuse represents one of the most common forms nowadays. According to the literature, sexting-the sharing of sexually explicit messages or images-is one of the most important risk factors for image-based sexual abuse because sexts can be forwarded or published without the authorization of the originator. Nevertheless, sexting can play a role in sexual and relational development and serve as a first step in experimenting with sexual contact in real life. In this study ( N  = 603 from the general population), we examined the relations between people's beliefs about sexting, attitudes toward it, and sexting behavior on the one hand, and reactions to a situation of nonconsensual dissemination of sexts on the other hand. Results showed that social pressure exerted by peers and partners to sext was associated with both positive attitudes toward sexting and sexting behaviors. Attitudes toward sexting, then, have a spillover effect on the reactions toward a victim of nonconsensual dissemination of sexts, in terms of empathy, victim blaming, and affective reactions. Implications for both research and policymaking regarding this form of gender-based violence are discussed.

Social science research has highlighted "honor" as a central value driving social behavior in Mediterranean societies, which requires individuals to develop and protect a sense of their personal self-worth and their social reputation, through assertiveness, competitiveness, and retaliation in the face of threats. We predicted that members of Mediterranean societies may exhibit a distinctive combination of independent and interdependent social orientation, self-construal, and cognitive style, compared to more commonly studied East Asian and Anglo-Western cultural groups. We compared participants from eight Mediterranean societies (Spain, Italy, Greece, Turkey, Cyprus [Turkish Cypriot and Greek Cypriot communities], Lebanon, Egypt) to participants from East Asian (Korea, Japan) and Anglo-Western (the United Kingdom, the United States) societies, using six implicit social orientation indicators, an eight-dimensional self-construal scale, and four cognitive style indicators. Compared with both East Asian and Anglo-Western samples, samples from Mediterranean societies distinctively emphasized several forms of independence (relative intensity of disengaging [vs. engaging] emotions, happiness based on disengaging [vs. engaging] emotions, dispositional [vs. situational] attribution style, self-construal as different from others, self-directed, self-reliant, self-expressive, and consistent) and interdependence (closeness to in-group [vs. out-group] members, self-construal as connected and committed to close others). Our findings extend previous insights into patterns of cultural orientation beyond commonly examined East-West comparisons to an understudied world region.

As the literature highlights, many health behavior theories try to explain both social and psychological variables influencing an individual's health behavior. This study integrates insights relative to the antecedents of getting vaccinated from health behavior theories, particularly including the health belief model (HBM), the theory of planned behavior (TPB), and the different socio-demographic factors. Furthermore, we considered the possible mechanism of impact of distrust in science on individuals' hesitance and resistance to taking up SARS-CoV-2 vaccination in subjects living in Italy. A correlational study of 1095 subjects enrolled when the national vaccination campaign for the third dose was launched. A questionnaire was used to measure: Italian Risk Perception; subjective norm; trust in science, trust in the vaccine; fear of COVID-19; fear of the vaccine; perceived knowledge about SARS-CoV-2; booster vaccination intention. Principal results show that: (i) the positive relationship provided by HBM theory between perceptions of SARS-CoV-2 risk (vulnerability and severity) and intention to have the vaccine, through fear of COVID-19; (ii) the positive relationship between subjective norms and both trust in science and vaccination intention; (iii) that trust in science plays a crucial role in predicting vaccination intention. Finally, the results provided indications about a positive relationship between subjective norms and fear of COVID-19, and a full mediation role of trust in science in the relationships between determinants of both TPA and HBM, fear of COVID-19, and vaccination intention. In conclusion, an individual's intention (not) to get vaccinated requires the consideration of a plethora of socio-psychological factors. However, overall, trust in science appears to be a key determinant of vaccination intention. Additional strategies promoting healthy behavior are needed.

This article examined indirect consequences for the victims of intimate partner violence (IPV) in terms of ostracism and reputational threats. Through an experimental vignette survey, we compared bystanders' reactions to either an intimate partner violence episode or a generic violence episode. A victim of IPV (vs. generic violence) received a more negative moral evaluation and was considered as more responsible for the violence perpetrated on her. This made participants not only anticipate a less positive reputation attributed to the victim but also report less willingness to approach and defend the victim and include her in relevant ingroups 1 year after the episode.

Organizational identification (OI) has increasingly attracted scholarly attention as a key factor in understanding organizational processes and in fostering efficient human resource (HR) management. Available evidence shows that organizational ethical climate crucially predicts OI, a key determinant of both employees' attitudes and behaviors. In the present paper, we examined the relationship between two specific ethical climates (self-interest vs. friendship), distributed leadership (DL), and employees' attitudes and behaviors, incorporating OI as a core underlying mechanism driving these relationships. Three hundred and forty-two employees filled out questionnaires to examine ethical climate, DL, OI, and a series of measures concerning attitudes and behaviors toward the organization. Structural equation modeling confirmed that a perception of an ethical climate of friendship (but not self-interest) fostered OI, which elicited higher commitment, perceived trust and recommendation, and lower turnover intention. Perception of DL further contributed to increasing OI. Our findings suggest that HR practices should carefully consider employee perceptions of a collectivistic (vs. individualistic) ethical climate, together with perceptions of DL, as key determinants of positive organizational outcomes. We discuss results in light of the social identity approach and present practical implications for HR management., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2021 Barattucci, Teresi, Pietroni, Iacobucci, Lo Presti and Pagliaro.)
