ABSTRACT
Background: Severe neonatal jaundice (SNJ) and the associated long-term health sequelae are a significant problem in low-income countries (LIC) where measurement of total serum bilirubin (TSB) is often unavailable. Transcutaneous bilirubinometry (TcB) provides the opportunity for non-invasive, point-of-care monitoring. Few studies have evaluated its agreement with TSB levels during phototherapy in LIC.Aim: To determine agreement between TcB and TSB during phototherapy in a Haitian newborn population and to establish whether TcB can be safely used to guide treatment during phototherapy when TSB is unavailable.Methods: A single-centre prospective study (February to May 2017) in Cap Haïtien, northern Haiti was undertaken. Newborns <7 days of age with clinically detected jaundice were eligible for inclusion. A TcB device (JM-103) was used to screen for newborn jaundice along with a parallel TSB. A strip of black tape was placed across the sternum during phototherapy and uncovered for subsequent TcB measurements. Decisions about phototherapy treatment were based upon UK National Institute of Clinical Excellence (NICE) threshold criteria. Paired TSB and TcB measurements were compared using Bland-Altman methods.Results: The final analysis included 70 parallel TSB/TcB measurements from 35 infants within the first 5 days of life. Nineteen (54.3%) were male and 12 (34.3%) were <35 weeks. Thirty-two (91.4%) were receiving phototherapy. There was good agreement between TSB and TcB. Compared with TSB, TcB tended to over-estimate bilirubin (mean difference 11.1 µmol/L, 95% CI -10.2-32.5 µmol/L). However, at higher bilirubin levels (>250 µmol/L), TcB tended to under-estimate bilirubin compared with TSB and the difference increased.Conclusion: In an LIC setting in which serum bilirubin testing is not commonly available, TcB demonstrates good agreement with TSB and can be safely used to guide jaundice treatment during phototherapy but can lead to over-treatment at lower bilirubin levels and are more inaccurate at higher levels. For TcB levels >250 µmol, confirmation with serum bilirubin should be performed, if available, to avoid under-estimation.Abbreviations: LIC: low income countries; LMIC: low and middle income countries; TcB: transcutaneous bilirubinometry; TSB: transcutaneous serum biliubin.

The experiment presented is the result of a partnership between the Paris-Nanterre University (CLIPSYD laboratory, EA 4430) and the CSAPA Imagine (Simone Veil Hospital, GH Eaubonne-Montmorency). Virtual reality immersion exposure for pathological gamblers is beneficial in the context of cognitive and behavioral interventions. It can be used to evoke the desire to play and to have access to automatic thoughts and mistaken beliefs of the players when they find themselves in a gambling context. Exposure is used until the urge to play diminishes and disappears which is the process of desensitization or extinction. OBJECTIVE: The objective of the study was to investigate the possibilities implemented by virtual reality in the case of an exhibition for pathological gamers to create a desire to play and work with the patient in an environment identical to the ecological one. Two hypotheses were proposed. On the one hand, the virtual reality exhibition will help to change the desire to play in relation to the game. On the other hand, virtual exhibition sessions associated with cognitive restructuring will have a greater impact on the perception of reality. METHOD: After a diagnosis was made, participation in the study was offered to patients (n=10) in routine care and able to participate (exclusion criteria). It consisted of four virtual reality exposure sessions integrated with traditional care. Exposure did not exceed 20minutes. To carry out this study we used the virtual reality headset "Oculus Rift CV1" and the headphones measuring EEG waves, "Emotiv Epoc". A battery of questionnaires were proposed to evaluate gambling-related behaviors (ICJP, GRCS, UPPS), to analyze the interest of the virtual reality exhibition (SIS, CGI, TEI, EVA), and to glimpse the immersion abilities (QEP and QPI). RESULTS: Ten participants aged 25 to 60 agreed to participate in the study. The results of this study demonstrated the viability of RV gamers' exposure as a tool that can help reduce pathological gambling symptoms and the severity perceived by therapists (CPI: t=1.6, P=0.001; CGI: t=4.87, P=0.001) between the beginning of the care and the end of the care and at D+1. We were also able to observe significant results (P<0.05) concerning a decrease in cognitive distortions (GRCS tot, Illusion of control, Power of prediction, Favorable interpretation). CONCLUSION: The feasibility study shows that the desire to play is very present during the virtual reality exhibition in accordance with literature studies. The results also demonstrate the utility of virtual reality to allow the patient to elaborate on the cognitive distortions associated with the practice of pathological gambling. From a therapeutic point of view, the results suggest that virtual reality can increase the effectiveness of cognitive restructuring and increase understanding of the urge to play related to stimuli in the environment of play.
