Determinants of Post-Traumatic Stress Disorders in Italian university students during the Covid-19 outbreak: the leading role of sex, health concerns, and health engagement.

Background: The unprecedented changes in daily-life caused by Covid-19 restrictions had many psycho-logical and adverse effects, not only in sufferers but also in the general population, including university students. To date, little is known about Post-Traumatic Stress Disorder symptoms experienced by university students during the peak of Covid-19 in Italy. Thus, the study describes Post-Traumatic Stress Disorders related to the Covid-19 outbreak among Italian university students and identifies the psychological distress risk and protective factors. Study design: A multicentre observational cross-sectional study. Methods: Data collection was involved in a self-reported web questionnaire, using the on-line platform Qualtrics®, in March and April 2020, involving convenience and consecutive sampling of Italians university students in different Italy regions. Results: A sample of 720 Italian university students was enrolled. Data analysis highlighted the leading role of sex, health concerns, and health engagement as negative or positive determinants of Post-Traumatic Stress Disorders in Italian university students during the Covid-19 outbreak. In particular, it is very insightful having discovered that health engagement is a protective factor of students' mental health. Conclusions: This is the first study identifying sex, health issues and health commitment as positive or negative determinants of Post-Traumatic Stress Disorders symptoms in Italian university students during the Covid-19 epidemic. Accordingly, this new achievement could be the starting point for the development of awareness campaigns for the psychological health of Italian university students.

The state of the evidence about the Synergy Model for patient care.

AIM: To systematically and critically summarize the state of the evidence about the Synergy Model and its utilization in nursing practice. BACKGROUND: The Synergy Model emphasizes the importance of alignment between patient needs and nurse competencies in achieving adequate patient- and nurse-related outcomes. It is a relatively new patient-centred care model developed at the end of the 1990s. INTRODUCTION: Despite the Synergy Model's potential to support patient-centred care, its practical application is still mainly limited. Thus far, literature about the Synergy Model has not yet been synthesized, undermining its broader utilization globally. METHODS: A systematic search was performed on the following databases: PubMed, CINAHL and Scopus. The authors used the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) statement and checklist to guide the systematic search; 26 papers were included in this study. A critical interpretative synthesis was adopted to summarize the data extracted from the included papers. RESULTS: Five interpretative themes emerged: conceptualization, experiences from the field, nursing education, patient-related outcomes and system-related outcomes. Synergy Model shows a precise theoretical definition, and it was implemented in multiple clinical settings, mainly in critical care contexts. It seems to have a positive influence on patient-related, nurse-related and system-related outcomes. DISCUSSION: Synergy Model seems to be positively associated with specific susceptible outcomes, such as patient satisfaction, reduction of patient's complications, staff satisfaction, empowerment, and engagement of patients and healthcare providers. However, the level of evidence is still limited. CONCLUSION: Future international research should demonstrate the feasibility of implementing the Synergy Model at an international level. More empirical research is needed to demonstrate the effectiveness of the model on susceptible outcomes. IMPLICATIONS FOR NURSING AND HEALTH POLICY: This systematic review could support further development of international programmes based on the Synergy Model. The Synergy Model's implementation has the potential to optimize nursing competencies, patient- and nurse-related outcomes.

Dark Matter Search Results from the PICO-60 C_{3}F_{8} Bubble Chamber.

New results are reported from the operation of the PICO-60 dark matter detector, a bubble chamber filled with 52 kg of C_{3}F_{8} located in the SNOLAB underground laboratory. As in previous PICO bubble chambers, PICO-60 C_{3}F_{8} exhibits excellent electron recoil and alpha decay rejection, and the observed multiple-scattering neutron rate indicates a single-scatter neutron background of less than one event per month. A blind analysis of an efficiency-corrected 1167-kg day exposure at a 3.3-keV thermodynamic threshold reveals no single-scattering nuclear recoil candidates, consistent with the predicted background. These results set the most stringent direct-detection constraint to date on the weakly interacting massive particle (WIMP)-proton spin-dependent cross section at 3.4×10^{-41} cm^{2} for a 30-GeV c^{-2} WIMP, more than 1 order of magnitude improvement from previous PICO results.
