Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries
Abstract
Background
Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres.
Methods
This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and lowâmiddle-income countries.
Results
In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of âsingle-useâ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for lowâmiddle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia.
Conclusion
This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both highâ and lowâmiddleâincome countries

Modeling and imaging of ground penetrating radar data
textGround Penetrating Radar (GPR) is an active and non-invasive
exploration technique based on the propagation of electromagnetic waves in the
subsurface. Modeling of GPR data is important because it helps us with data
interpretation and forms the basis (solution to the forward problem) for most
iterative inversion techniques. Conversely, migration (or imaging) is a type of
inversion technique (backward propagation) that creates an image related to the
subsurface reflectivity and can be used to estimate the model parameters of the
media that affect the propagation of the waves. However, for practical
applications, modeling and migration techniques must be fast, accurate and
efficient.
I have developed a fast, efficient and accurate GPR modeling technique
for stratified media (isotropic and laterally homogeneous layers) based on the
invariant imbedding or reflectivity technique. To test the results obtained with this
technique, and have a general tool for modeling of GPR data in heterogeneous,
dispersive and isotropic media, I have implemented a 3D explicit Finite
Difference Time Domain (FDTD) technique. The FDTD formalism is presented
in conjunction with a discussion of the electromagnetic dispersion mechanisms
that affect the GPR signal in most geologic media. I show that the results obtained
with the reflectivity and FDTD techniques are nearly identical for laterally
homogeneous media. Real GPR data is used to study the capabilities and practical
aspects that affect the accuracy of the reflectivity technique.
I have developed a new technique for migration of GPR data in
heterogeneous and lossy media. I have implemented the technique in 2D media
and presented the formalism for its extension to 3D media. The new technique,
based on the Split Step Fourier migration technique, allows us to efficiently
include the dispersion and attenuation effects in the media. An approximation of
homogeneous plane waves, which do not add new restrictions to the Split Step
Fourier technique, gives greater stability to the imaging technique allowing us to
migrate the data through thicknesses up to three times the characteristic skin
depths of the media computed at the dominant frequency of the GPR signal.Geological Science
The influence of anxiety and personality factors on comfort and reachability space a correlational study
Although the effects of several personality factors on interpersonal space (i.e. social space within personal comfort area) are well documented, it is not clear whether they also extend to peripersonal space (i.e. reaching space). Indeed, no study has directly compared these spaces in relation to personality and anxiety factors even though such a comparison would help to clarify to what extent they share similar mechanisms and characteristics. The aim of the present paper was to investigate whether personality dimensions and anxiety levels are associated with reaching and comfort distances. Seventy university students (35 females) were administered the Big Five Questionnaire and the State-Trait Anxiety Inventory; afterwards, they had to provide reachability- and comfort-distance judgments towards human confederates while standing still (passive) or walking towards them (active). The correlation analyses showed that both spaces were positively related to anxiety and negatively correlated with the Dynamism in the active condition. Moreover, in the passive condition higher Emotional Stability was related to shorter comfort distance, while higher cognitive Openness was associated with shorter reachability distance. The implications of these results are discussed
The effect of facial expressions on peripersonal and interpersonal spaces
Identifying individuals' intent through the emotional valence conveyed by their facial expression influences our capacity to approach-avoid these individuals during social interactions. Here, we explore if and how the emotional valence of others' facial expressiveness modulates peripersonal-action and interpersonal-social spaces. Through Immersive Virtual Reality, participants determined reachability-distance (for peripersonal space) and comfort-distance (for interpersonal space) from male/female virtual confederates exhibiting happy, angry and neutral facial expressions while being approached by (passive-approach) or walking toward (active-approach) them. Results showed an increase of distance when seeing angry rather than happy confederates in both approach conditions of comfort-distance. The effect also appeared in reachability-distance, but only in the passive-approach. Anger prompts avoidant behaviors, and thus an expansion of distance, particularly with a potential violation of near body space by an intruder. Overall, the findings suggest that peripersonal-action space, in comparison with interpersonal-social space, is similarly sensitive to the emotional valence of stimuli. We propose that this similarity could reflect a common adaptive mechanism shared by these spaces, presumably at different degrees, for ensuring self-protection functions

Comunicare l'istituzione. L'UniversitĂ come narrazione.
Una riflessione sul progetto di comunicazione per le istituzioni pubbliche come occasione per parlare di grafica di Pubblica UtilitĂ . Il volume racconta il caso del progetto di re-branding dell'UniversitĂ della Campania Luigi Vanvitelli, ma coglie l'occasione per costruire un punto di vista critico rispetto alle metodologie che un Ateneo deve poter adottare per comunicare la propria policy e sul proprio ruolo di attore pubblico
