The Body Image Virtual Reality Assessment (BIVRA): Measuring the body representation through virtual reality.

Our physical and psychological well-being is significantly influenced by how we perceive our body, in addition to our thoughts and emotions associated with it. Dysfunctional body perceptions and attitudes play a key role in the development and maintenance of severe conditions such as eating disorders in both males and females. Given its relevance, some attempts have been made to improve body image assessment methods in terms of perceptual accuracy and body satisfaction taking advantage of technological advances such as virtual reality. However, existing applications have mainly focused on women and clinical conditions. In this study, we presented the Body Image Virtual Reality Assessment (BIVRA), a virtual reality figure rating scale to assess body image in both male and female subjects. We tested BIVRA's ability to measure perceptual accuracy and compared its results with a standardized body satisfaction questionnaire. Additionally, we investigated gender differences. BIVRA was found to be effective in assessing body image. We observed that a perceptually based task successfully captured both low and high levels of body representations, shedding light on the significant gender differences. The association between BIVRA and the body satisfaction questionnaires was moderated by gender, with a stronger association for women. While further validation of BIVRA is needed to fully exploit its potential, our results suggest that the integration of virtual reality into the assessment of body image and related disorders may significantly enhance our understanding of individuals struggling with body image issues and has the potential to advance current methods and techniques.

The multisensory mind: a systematic review of multisensory integration processing in Anorexia and Bulimia Nervosa.

Individuals with Anorexia Nervosa and Bulimia Nervosa present alterations in the way they experience their bodies. Body experience results from a multisensory integration process in which information from different sensory domains and spatial reference frames is combined into a coherent percept. Given the critical role of the body in the onset and maintenance of both Anorexia Nervosa and Bulimia Nervosa, we conducted a systematic review to examine multisensory integration abilities of individuals affected by these two conditions and investigate whether they exhibit impairments in crossmodal integration. We searched for studies evaluating crossmodal integration in individuals with a current diagnosis of Anorexia Nervosa and Bulimia Nervosa as compared to healthy individuals from both behavioral and neurobiological perspectives. A search of PubMed, PsycINFO, and Web of Sciences databases was performed to extract relevant articles. Of the 2348 studies retrieved, 911 were unique articles. After the screening, 13 articles were included. Studies revealed multisensory integration abnormalities in patients affected by Anorexia Nervosa; only one included individuals with Bulimia Nervosa and observed less severe impairments compared to healthy controls. Overall, results seemed to support the presence of multisensory deficits in Anorexia Nervosa, especially when integrating interoceptive and exteroceptive information. We proposed the Predictive Coding framework for understanding our findings and suggested future lines of investigation.

Diagnoses of Anorexia Nervosa and Bulimia Nervosa have increased dramatically in recent years, taking on the characteristics of a mental health emergency. More research is therefore needed to better understand these conditions, especially given their complex and multifaceted nature. Patients affected by these conditions report significant alterations in body-self experience. Body experience results from a cross-modal integration process in which information from different sensory modalities and spatial frames is combined. Therefore, we systematically reviewed studies that focused on multisensory integration in patients affected by Anorexia Nervosa and Bulimia Nervosa, as it may play a key role in the onset and maintenance of these pathologies. Studies in this review found multisensory integration difficulties in patients with Anorexia Nervosa, but not enough studies were retrieved to draw conclusions regarding Bulimia Nervosa. We discussed findings trying to link behavioral, neuropsychological, and neuroscientific evidence in light of the predictive coding framework to provide a different perspective on patients' distorted body experiences. This may lead to new insights to refine our understanding of these complex and poorly understood disorders.

[Tracheal rupture treated with robotic surgery: the importance of evidence-based practice in nursing management. A case report]. / Rottura tracheale trattata con chirurgia robotica: l'importanza dell'evidence-based practice nella gestione infermieristica. Un caso clinico.

. Tracheal rupture treated with robotic surgery: the importance of evidence-based practice in nursing management. A case report. Tracheal rupture is a very rare condition with high morbidity and mortality. While it has a multifactorial etiology, however it occurs most frequently after orotracheal intubation. The case of a 76-year-old woman who underwent out-of-hospital orotracheal intubation for severe respiratory failure due to a state of coma is described. The patient suddenly developed a subcutaneous emphysema extending from the chest to the skull due to tracheal laceration. The management of the case is described with special focus on nursing goals to prevent ventilator associated pneumonia and mediastinitis, avoid the endotracheal tube dislocation and further tracheal injuries. The case presented underlines the importance of a systematic recourse to evidence-based practice (EBP), which allowed to effectively manage a complex situation.

High dose esomeprazole as an anti-inflammatory agent in sepsis: Protocol for a randomized controlled trial.

BACKGROUND: Sepsis is caused by dysregulated immune responses due to infection and still presents high mortality rate and limited efficacious therapies, apart from antibiotics. Recent evidence suggests that very high dose proton pump inhibitors might regulate major sepsis mediators' secretion by monocytes, which might attenuate excessive host reactions and improve clinical outcomes. This effect is obtained with doses which are approximately 50 times higher than prophylactic esomeprazole single daily administration and 17 times higher than the cumulative dose of a three day prophylaxis. We aim to perform a randomized trial to investigate if high dose esomeprazole reduces organ dysfunction in patients with sepsis or septic shock. METHODS: This study, called PPI-SEPSIS, is a multicenter, randomized, double blind, placebo-controlled clinical trial on critically ill septic patients admitted to the emergency department or intensive care unit. A total of 300 patients will be randomized to receive high dose esomeprazole (80 mg bolus followed by 12 mg/h for 72 h and a second 80 mg bolus 12 h after the first one) or equivolume placebo (sodium chloride 0.9%), with 1:1 allocation. The primary endpoint of the study will be mean daily Sequential Organ Failure Assessment (SOFA) score over 10 days. Secondary outcomes will include antibiotic-free days, single organ failure severity, intensive care unit-free days at day 28, and mortality. DISCUSSION: This trial aims to test the efficacy of high dose esomeprazole to reduce acute organ dysfunction in patients with septic shock. TRIAL REGISTRATION: This trial was registered on ClinicalTrials.gov with the trial identification NCT03452865 in March 2018.

Early versus late tracheostomy for traumatic brain injury: a systematic review and meta-analysis.

INTRODUCTION: Tracheostomy is the most frequent bedside surgical procedure performed on patients with traumatic brain injury who require mechanical ventilation. To compare the effects of early tracheostomy vs. late tracheostomy on the duration of mechanical ventilation in patients with traumatic brain injury, we carried out a systematic review and meta-analysis. EVIDENCE ACQUISITION: MEDLINE, Scopus, Web of Science, and Cochrane were searched from inception to 17th October 2022. Eligible clinical trials and observational studies reporting early versus late tracheostomy in TBI were searched. Two reviewers extracted data and independently assessed the risk of bias. The duration of mechanical ventilation was the primary outcome. EVIDENCE SYNTHESIS: We pooled standardized mean differences and risk differences for random effects model. A total of 368 studies were retrieved and screened. Nineteen studies were selected, including 6253 patients. Mean time for early tracheostomy and late tracheostomy procedures was 6±2.9 days and 17±10.7 days, respectively. Early tracheostomy was associated with shorter mechanical ventilation duration (SMD=-1.79, 95% CI -2.71; -0.88) and fewer ventilator associated pneumonia (RD=-0.11, 95% CI -0.16; -0.06) when compared with late tracheostomy. Moreover, intensive care unit (ICU) (SMD=-1.64, 95% CI -2.44; -0.84) and hospital (SMD=-1.26, 95% CI -1.97; -0.56) length of stay were shorter when compared with late tracheostomy. CONCLUSIONS: The findings from this meta-analysis suggest that early tracheostomy in severe TBI patients contributes to a lower exposure to secondary insults and nosocomial adverse events, increasing the opportunity of patient's early rehabilitation and discharge.

Beneficial effects of levosimendan to wean patients from VA-ECMO: a systematic review and meta-analysis.

INTRODUCTION: Patients with refractory cardiogenic shock can benefit from veno-arterial extracorporeal membrane oxygenation (VA-ECMO). The use of levosimendan in VA-ECMO patients may facilitate weaning and enhance survival. EVIDENCE ACQUISITION: MEDLINE, Scopus, Web of Science, and Cochrane were searched from inception to October 10th, 2021. Eligible clinical trials and observational studies reporting the use of levosimendan in VA-ECMO were searched. Two reviewers extracted data and independently assessed the risk of bias. To integrate the data, a random-effect model was applied. The success of weaning from VA-ECMO was the primary outcome. EVIDENCE SYNTHESIS: Ten observational studies, including a total of 987 patients, were identified. Levosimendan was associated with successful weaning (362/448) compared with controls (328/539) (OR 2.37, 95% CI 1.71-3.28; P=0.01) and reduced mortality (144/433 vs. 258/507) (nine studies, OR 0.53, 95% CI 0.36-0.78; P=0.01) compared with control. CONCLUSIONS: Levosimendan was associated with successful weaning and increased survival in VA-ECMO patients. Randomized trials should confirm these findings.

Efficacy of Multisensory Technology in Post-Stroke Cognitive Rehabilitation: A Systematic Review.

Post-stroke, in addition to sensorimotor signs and symptoms, could lead to cognitive deficits. Theories of embodiment stress the role of sensorimotor system and multisensory integration in sustaining high-order cognitive domains. Despite conventional post-stroke cognitive rehabilitation being effective, innovative technologies could overcome some limitations of standard interventions and exploit bodily information during cognitive rehabilitation. This systematic review aims to investigate whether 'multisensory technologies' compared to usual care treatment can be a viable alternative for cognitive rehabilitation. By applying PRISMA guidelines, we extracted data and assessed the bias of 10 studies that met the required criteria. We found that multisensory technologies were at least comparable to standard treatment but particularly effective for attention, spatial cognition, global cognition, and memory. Multisensory technologies consisted principally of virtual reality alone or combined with a motion tracking system. Multisensory technologies without motion tracking were more effective than standard procedures, whereas those with motion tracking showed balanced results for the two treatments. Limitations of the included studies regarded the population (e.g., no study on acute stroke), assessment (e.g., lack of multimodal/multisensory pre-post evaluation), and methodology (e.g., sample size, blinding bias). Recent advancements in technological development and metaverse open new opportunities to design embodied rehabilitative programs.

Ventriculo-arterial coupling in the intensive cardiac care unit: A non-invasive prognostic parameter.

AIMS: The aim of this study was to investigate the relationship between ventriculo-arterial coupling (VAC) and in-hospital outcomes and to assess the prognostic value of VAC in critically ill patients. METHODS AND RESULTS: A total of 329 consecutive patients (mean age 66,7 ± 15.5 years, 66.9% male) admitted to the intensive cardiac care unit of the Sandro Pertini Hospital, Rome (Italy) between January 2019 and December 2019, were included in the study. All patients underwent blood pressure measurement and non-invasive, echocardiography-derived estimates of left ventricular end-systolic elastance (Ees), arterial elastance (Ea) and VAC in a single-beat determination using the iElastance© application. In-hospital events related to acute heart failure and hypoperfusion were recorded and need for invasive ventilation, intra-aortic balloon pump, renal replacement therapy and death were considered as composite. Overall, 39 patients (11,8%) experienced in-hospital complications (group C), and 290 (88,2%) did not (group NoC). Ea and VAC were found to be significantly higher in group C than in group NoC, and a trend toward decreased Ees was observed in group C. VAC was a strong and independent predictor of in-hospital clinical outcome both at univariable and multivariable analysis adjusted for comorbidities [OR (95% CI): 1.868 (1.141-3.059); P = 0.013] and hemodynamic parameters [OR (95% CI): 1674 (1018-2755); P = 0.042]. CONCLUSION: VAC might be an additional non-invasive prognosticator of outcome in critically ill patients.

Preventing Severe Acute Respiratory Syndrome Coronavirus-2 Exhalation Upon Tracheal Extubation in the Intensive Care Unit: A Case Series.

Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) is a highly infectious virus transmitted by inhalation of infected matter containing live virus or by exposure from contaminated surfaces. Aerosol-generating procedures (AGPs) create an increased risk of airborne transmission of infection. Tracheal extubation of coronavirus disease 2019 (COVID-19) patients in the intensive care unit (ICU) is a risky AGP procedure owing to the proximity of the staff members to the patients' mouths and the exposure to airway secretions. We describe the use of a disposable openable mask (Janus Mask, Biomedical Srl, Florence, Italy) that might limit aerosol generation in the periextubation phase of COVID-19 cardiac surgical patients.

Strain elastography for the assessment of skin nodules in dogs.

BACKGROUND: Strain elastography (SE) is a modern imaging technology that provides an additional way of evaluating the changes in soft tissue elasticity caused by pathophysiological processes. Despite its widespread use in human medicine, only a few studies on the application of SE in veterinary medicine are available. OBJECTIVES: To evaluate the potential usefulness of SE as an integrative imaging model in the standard ultrasound technique to better discriminate between inflammatory and neoplastic skin nodules in dogs. ANIMALS: Fifty-one client-owned dogs with clinical evidence of single or multiple skin nodules detected during routine dermatological examination. METHODS AND MATERIALS: Margins, echogenicity, echo-structure, calcification and vascularisation of 65 skin nodules were assessed with ultrasound, and SE was used to score qualitative (E-score, E-index, E2) and semiquantitative (SR) parameters. A comparison of diagnostic yields with cytological and histological findings as the gold standard was performed. RESULTS: Mast cell and benign follicular tumours showed the highest E-scores and SRs among neoplastic nodules; statistically significant differences were not detected. Calcific and nonvascularised nodules showed significantly higher E-index values than the others. Overall, a negative correlation was observed between the longitudinal diameter of skin nodules and the qualitative elastic parameters. CONCLUSIONS AND CLINICAL IMPORTANCE: In this study, SE proved to be useful to identify only a subset of nodules such as mast cells and hair follicular tumours. Although evidence supporting the use of SE in evaluating skin nodules was demonstrated to below, indicators to guide further research were developed.
