Abstract
Children and adolescents with externalizing problems show physiological hypo-reactivity toward affective stimuli, which may relate to their disruptive, antisocial, and thrill-seeking behaviors. This study examines differences in explicit and implicit emotion regulation between preadolescents with and without externalizing problems as well as the role of emotion regulation in subjective and autonomic responses to emotional stimuli. Preadolescents showing self- and other-reported externalizing psychopathology, and a control sample, without such difficulties, participated in a passive affective picture-viewing task with neutral, fearful, joyful, and sad images, while their heart rate and heart rate variability were measured. Participants also reported on their emotion regulation difficulties using the Difficulties in Emotion Regulation Scale. Compared to controls, youths scoring high on externalizing problems (1) reported greater emotion regulation difficulties, especially a lack of emotional clarity and difficulty in controlling impulsive actions, (2) showed higher resting heart rate variability and a lower resting heart rate, suggestive of higher emotion/autonomic regulation ability, and (3) showed both subjective and physiological hypo-arousal to emotional pictures. Heart rate variability and, to a lesser degree difficulties in emotional clarity, modulated the effects of emotional pictures on subjective and physiological arousal. Findings suggest that interventions to improve emotion regulation and awareness may help to prevent externalizing problems.

Abstract
PURPOSE The aim of this study was to evaluate the results of distal femoral fracture fixation of two different methods, lateral locking plate (LP) or an Intra-medullary nail (IMN), in patients managed in our institution. More specifically, to assess: (a) if there was a difference in functional outcomes between the LP and IMN groups; (b) whether the rate of complications was different between the two groups. METHODS Between January 2009 and December 2018 adult patients with distal femoral fractures managed in our unit with either LP or IMN for extra and intra-articular fractures were eligible to participate. Demographic details, fracture type, procedures performed, time to union, complications and functional scores (Oxford Knee Score) were recorded and analysed. The mean follow up was 4 years (12-120 months). RESULTS Out of 193 patients who met the inclusion criteria, 93 received an IMN whereas 100 patients were treated with LP. Mean age was 64.2 (18-99) and 70.1 (18-100) for the IMN and LP groups respectively. Overall, the two groups had similar demographics and there was no significant difference in the type of fractures sustained (p > 0.05). The Oxford Knee Score was highest for patients fixed with LP, mean 37.3 (6-48, SD 7.3) versus 28.4 (3-48, SD 14.4), (p = < 0.02) compared to the IMN group. In terms of complications, the rate of non-union was higher in the LP group 8.6% versus 4% in those patients treated with an IMN, p value < 0.01. CONCLUSION While the rate of non-union was higher in the LP group and the functional results were superior in the plating group.

Abstract
Well-defined statistical copolymers of n-hexyl isocyanate, HIC, and 3-(triethoxysilyl)propyl isocyanate, TESPI, were synthesized via coordination polymerization mechanism, employing a chiral half-titanocene complex as initiator. The monomer reactivity ratios of the statistical copolymers were calculated using linear graphical methods and the computer program COPOINT in the frame of the terminal model. The molecular and structural characteristics of the copolymers were also calculated. The kinetics of the thermal decomposition of the statistical copolymers was studied by Thermogravimetric Analysis, TGA, and Differential Thermogravimetry, DTG, and the activation energy of this process was calculated employing several theoretical models. In addition, block copolymers constituted from PHIC and PTESPI blocks were synthesized by sequential coordination polymerization. All samples were characterized by nuclear magnetic resonance, NMR, spectroscopy and size exclusion chromatography, SEC. The thermal stability of the blocks was also studied by TGA and DTG and compared to the corresponding statistical copolymers.

Abstract
Aim COVID-19 has led to unprecedented waiting times for elective surgery. Optimising patient pathways is paramount in tackling the backlog. Length of hospital stay (LOS) is an accepted surrogate for successful elective surgery. The aims of our study were: 1) report on changes in LOS after restarting our elective THA service; 2) identify barriers to early discharge, 3) investigate effectiveness of implemented changes. Method A retrospective review of consecutive patients undergoing elective THA, comparing three groups: 1) enhanced care pathway (n=96; 09/2019–12/2019); 2) COVID group (n=56; 03/2021–04/2021); 3) intervention group (n=96; 05/2021–08/2021). Results LOS in the enhanced care pathway group was 2.6 ±2.1 days. During initial resumption of elective operating (COVID group) the LOS was 4.8 ±4.5 days (statistically significant increase; p=0.011). Factors affecting LOS included reduced physiotherapy provision; lack of pre-operative occupational therapy review; loss of educational classes and worse pre-operative functional status. To address these our department employed three new physiotherapists, introduced training for nursing staff and created a post-operative proforma. The LOS subsequently reduced to 3.7 ±4.6days (p=0.166). Subgroup analysis of the intervention group showed age <75 (p<0.001) and ASA1–2 (p=0.036) were associated with reduced LOS (2.1±1.5 days). Other variables analysed did not significantly affect LOS. Conclusions COVID-19 has had a significant effect on LOS, which is still not reversed. For effective resumption of THA services, pre-pandemic enhanced care pathways should be reinstated. With current restrictions preventing face-to-face classes, online educational sessions could be offered. Those younger than 75 years and ASA1–2 are most likely to be discharged without delay.

Abstract
We examined whether young adults with internalizing psychopathology during the pre-COVID-19 pandemic period exhibited different patterns of emotional responses than those without such psychopathology during the implementation of the “lockdown” in Cyprus, Greece. Two-wave longitudinal research was conducted i one hundred six college students completing measures of affective experiences, mental health, and quality of life during the prepandemic and lockdown periods. Increased negative affect and internalizing symptoms during the prepandemic period and decreased positive affect and increased perceived stress during the lockdown period both significantly predicted increased internalizing symptoms during the lockdown period. We discuss findings within the context of actions and interventions for young adults with existing internalizing symptomatology during the COVID-19 pandemic.

Abstract
Abstract. Background: Increased perceived stress is associated with physical and mental health problems. However, little is known about the social factors that influenced perceived stress during the COVID-19 pandemic. In this study, we examined the relationship between social skills, perceived support from family and friends, and perceived stress during the COVID-19 pandemic, through a two-wave design. Methods: A group of 106 college students completed measures of social skills during the prepandemic period as well as of perceived social support and perceived stress 1 month into the implementation of the first lockdown in Cyprus. Results: Preexisting social skills and concurrent family support the predicted negatively perceived stress during the lockdown. Although several aspects of social skills were correlated negatively with perceived stress, only the ability to manage interpersonal conflicts and to effectively resolve disagreements negatively predicted perceived stress, suggesting that this skill may constitute a protective factor against perceived stress during stressful events. Perceived support during the pandemic, on the other hand, was not overall significantly predicted by one’s social skills. Conclusions: Our study provides preliminary evidence about the relationship between interpersonal skills and perceived stress during the COVID-19 pandemic. Interventions targeting the development of conflict resolution skills seem to be promising in ameliorating the psychological stress associated with the pandemic.

Abstract
Platelet products (PP) and bone-marrow aspirate are popular sources of osteoinductive signalling molecules and osteogenic bone marrow mesenchymal stromal cells (BM-MSCs) used in the treatment of impaired bone healing. However, the combined use of PP and BM-MSCs in clinical studies has reported mixed results. Understanding the cellular and molecular interactions between PP and BM-MSCs plays the important role of guiding future research and clinical application. This systematic review investigates the effects of PP on the biophysiological functions of BM-MSCs in in vitro human studies, including (i) proliferation, (ii) migration, (iii) differentiation, (iv) growth factor/cytokine/protein expression, (v) immunomodulation, (vi) chemotactic effect on haematopoietic stem cells, (vii) response to apoptotic stress, and (viii) gene expression. In vitro studies in human have demonstrated the multi-faceted 'priming effect' of PP on the biophysiological functions of BM-MSCs. PP has been shown to improve proliferation, migration, osteogenic differentiation, reaction to apoptotic stress as well as immunomodulatory, pro-angiogenic and pro-inflammatory capacities of BM-MSCs. Several factors are highlighted that restrict the transferability of these findings into clinical practice. Therefore, more collaborative in vitro research in humans modelled to reflect clinical practice is required to better understand the effects of PP exposure on the biophysiological function(s) of BM-MSCs in human.

Abstract
In this conceptual review, we discuss models of emotion and its regulation and identify a spectrum of processes that characterise adaptive adjustment to the affective environment. We describe a dynamic-phasic model of emotion processing and regulation, focusing on five stages: anticipation, response, recovery, habituation and rest as part of a cascade of responses to emotional challenges, as these become progressively expected, proximal, chronic or repeated. We argue for the need to investigate beyond simple reactivity to emotional stimuli, in order to understand mental and physical health conditions where emotional dysregulation plays a role. We propose that a hallmark of an effective and adaptive emotion regulation system is its flexibility, in the service of life goals and values. Consistent with McEwen's model (1998, Stress, adaptation, and disease: Allostasis and allostatic load. Annals of the New York Academy of Sciences, 840(1), 33-44), inflexible emotion regulation can lead to increased allostatic load, from frequent stress, inadequate reactivity, failed shutdown and habituation, which may result in physical and mental illness. Alexithymia exemplifies inflexible emotion regulation, with dysfunctions potentially across all stages of emotion processing, both psychologically and physiologically. These maladaptive processes and their consequence on allostatic load potentially explain the association between alexithymia and physical and mental illness.

Abstract
We examined emotional responses in Attention Deficit Hyperactivity and Oppositional Defiant/Conduct Disorder to affective pictures. Eighty seven children (42 female, Mage = 11.2), with clinical or subclinical symptoms and controls viewed joy, fear, sadness or neutral pictures while heart rate, skin conductance, corrugator and zygomaticus responses were recorded. The moderating role of Callous-Unemotional and anxiety traits was evaluated. Lower resting heart rate and decreased skin conductance across picture types was associated with ADHD symptoms. Decreased heart rate reactivity to fear and sad stimuli was associated with ADHD and ODD/CD. Corrugator and zygomaticus responses were not associated with ADHD or ODD/CD. Findings are mostly consistent with a fearlessness account of disruptive behavior, and seem to also pertain to ADHD, with intact valence systems. Findings are discussed in light of the significance of identifying common pathogenic mechanisms across traditional diagnostic categories, consistent with trans-diagnostic approaches to the study of psychopathology.

Abstract
BACKGROUND Cardiogenic shock is a life-threatening condition and patients might require rapid sequence induction (RSI) and mechanical ventilation. In this study, we evaluated a new RSI/mechanical ventilation protocol in patients with acute myocardial infarction complicated by cardiogenic shock. METHODS We included consecutive adult patients who were transferred to the emergency department. The RSI protocol included 5 phases: preoxygenation, pretreatment, induction/paralysis, intubation, and mechanical ventilation (PPIIM). A posteriori, we selected historical patients managed with standard RSI as a control group. The primary outcome was hemodynamic derangement or hypoxemia from enrollment until intensive care unit (ICU) admission. RESULTS We studied 31 consecutive patients who were intubated using the PPIIM protocol and 22 historical controls. We found significant differences in systolic (85.32 ± 4.23 vs 71.72 ± 7.98 mm Hg; P < 0.0001), diastolic (58.84 ± 5.84 vs 39.05 ± 5.63 mm Hg; P < 0.0001), and mean arterial pressure (67.71 ± 4.90 vs 49.90 ± 5.66 mm Hg; P < 0.0001), as well as in partial pressure of oxygen (85.80 ± 19.82 vs 164.73 ± 43.07 mm Hg; P < 0.0001) between the PPIIM and control group at 5 minutes of automated ventilation. Also, statistically significant differences were observed in diastolic (59.74 ± 4.93 vs 47.86 ± 11.47 mm Hg; P < 0.0001) and mean arterial pressure (68.65 ± 4.10 vs 60.23 ± 11.67 mm Hg; P < 0.0001), as well as in partial pressure of oxygen (119.84 ± 50.57 vs 179.50 ± 42.17 mm Hg; P < 0.0001), and partial pressure of carbon dioxide (39.81 ± 10.60 vs 31.00 ± 9.30 mm Hg; P = 0.003) between the 2 groups at ICU admission. Compared with the control group, with PPIIM more patients survived to ICU admission (100% vs 77%) and hospital discharge (71% vs 31.8%), as well as at 90 days (51.6% vs 18.2%), and at 180 days (38.7% vs 13.6%). CONCLUSIONS The PPIIM protocol allows safe intubation of acute myocardial infarction patients with cardiogenic shock and improves hemodynamic and oxygenation parameters.

Abstract
Aim This investigation examined the association between social anxiety and loneliness, and the role of associated characteristics specifically self-esteem, social skills and anxiety sensitivity, among young adults in Cyprus, and potential gender differences in the prediction of perceived loneliness. Method Questionnaires on loneliness, social skills, anxiety sensitivity and self-esteem were administered to a college sample in Cyprus. Results Mediated regression supported full mediation by social skills and self-esteem, but not by anxiety sensitivity in the association between social anxiety and loneliness. For men, loneliness was mostly predicted by anxiety sensitivity, but among women by poor social skills and lower self-esteem. For neither gender were these effects moderated by social anxiety level. Conclusion Social anxiety and loneliness are related but distinct constructs. Interventions focusing on social skill acquisition and practice, and anxiety tolerance for men may improve confidence and ultimately result in decreased loneliness among youth.

Abstract
Severe trauma and massive haemorrhage represent the leading cause of death and disability in patients under the age of 45 years in the developed world. Even though much advancement has been made in our understanding of the pathophysiology and management of trauma, outcomes from massive haemorrhage remain poor. This can be partially explained by the development of coagulopathy, acidosis and hypothermia, a pathological process collectively known as the “lethal triad” of trauma. A number of pharmacological adjuncts have been utilised to stop bleeding, with a wide variation in the safety and efficacy profiles. Antifibrinolytic agents in particular, act by inhibiting the conversion of plasminogen to plasmin, therefore decreasing the degree of fibrinolysis. Tranexamic acid, the most commonly used antifibrinolytic agent, has been successfully incorporated into most trauma management protocols effectively reducing mortality and morbidity following trauma. In this review, we discuss the current literature with regard to the management of haemorrhage following trauma, with a special reference to the use of pharmacological adjuncts. Novel insights, concepts and treatment modalities are also discussed.

Abstract
Managing Protected Areas (PAs) is a challenging task, and globally many instruments have been utilised for this purpose. Existing research demonstrates that the effectiveness of these instruments is highly dependent on their social acceptability among local communities resident within PAs. Consequently, investigating local attitudes and perceptions of Protected Area (PA) policies has been emphasised in recent studies. Drawing on empirical work conducted in two National Parks including river delta ecosystems designated as Ramsar wetlands in northern Greece, this paper examines local residents' perceptions of three hypothesized policy options (regulatory, market-based and participatory) for Park management. The influence of social capital elements (social trust, institutional trust and social networks) on residents' perceptions is explored. The findings reveal a high degree of importance attached by resident communities to Park designation in both PAs, though residents' perceptions of the proposed management options varied. The regulatory option was regarded as the least restrictive, while the most restrictive was perceived to be the market-based option. However, greater benefits were identified by residents from the market-based option, while the fewest benefits were considered to arise from the proposed regulatory option. Furthermore, local residents' perceptions were significantly shaped by the proposed management and decision-making structure offered under each policy option. The influence of different social capital elements on residents' perceptions also varied in the study sample, with social trust and institutional trust positively correlated with the benefits that were perceived to arise from the different policy options. Moreover, when social capital was measured as an aggregate indicator at the level of the individual, it was positively correlated with perceived environmental benefits.
