Összefoglaló. Bevezetés: A COVID–19-pandémia okozta nagyfokú betegszám-növekedés ellátásának érdekében az egészségügyi rendszerek gyakran a kórházak teljes átszervezésére kényszerültek. A szakállomány gyors és hatékony felzárkóztatása kulcsfontosságú ilyen körülmények között. A telepített kórházi egységek személyzetének felkészítésére a virtuális valóságban levezethető csoportos gyakorlatozás ígéretes módszernek mutatkozik. Célkitűzés: Célunk egy telepített kórház személyzetének felkészítésére alkalmazott virtuális szimulációs gyakorlatsorozat tapasztalatainak bemutatása, valamint a létrehozott és kipróbált virtuális gyakorlatcsomagok adaptálási lehetőségeinek elméleti bemutatása a COVID–19-kórházak személyzetének gyors felzárkóztatását szolgáló gyakorlatsorozat lehetséges kivitelezése érdekében. Módszer: Három, prototípusként előállított virtuális gyakorlat került alkalmazásba két próbatanfolyam keretén belül. A virtuális színterek kialakítására az XVR szimulációs szoftvert használtuk. A gyakorlatok alkalmazhatóságának és hasznosságának kiértékelésére anonim kérdőíves felméréseket készítettünk. Az adatok feldolgozásában kereszttábla-elemzést és khi-négyzet-próbát alkalmaztunk. Eredmények: A két próbaképzésen nyolc ország képviseletében összesen 76 gyakornok vett részt. A résztvevők 63,9%-a szerint a módszer alkalmas ilyen jellegű gyakorlatok levezetésére, de további fejlesztéseket igényel. Véleményük, hogy technikai használata „elég könnyen” elsajátítható (59,7%), és interaktív (90,32%), valósághű (45,0%) szimulációs közeget biztosít. Megbeszélés: Eredményeink alapján a virtuális valóság egy alkalmazható módszer a telepített kórházak szakállományának valós bevetésekre való felkészítésére. A létrehozott virtuális gyakorlatcsomagok tartalma és szerkezete könnyen adaptálható egy COVID–19 ideiglenes egészségügyi egység sajátos munkakörülményeihez való gyors személyzeti felzárkóztatást szolgáló műhelygyakorlatok megszervezéséhez. Következtetés: A virtuális valóság ígéretes oktatási eszköz, amely kiegészítheti a nagy költségekkel és bonyolult szervezéssel járó terepgyakorlatokat, megközelítve azok oktatási hatásfokát. A virtuális térben megélt tapasztalatok valós szakmai élményekké alakulnak, és hozzájárulnak egy biztonságos és hatékony munkaközeg gyors kialakításához. Orv Hetil. 2021; 162(40): 1591–1600. Summary. Introduction: COVID-19 pandemic imposed sudden increase in hospital admissions, thus medical systems needed to reorganize entire hospitals quite often. Quick and efficient training is of outmost importance. Virtual reality team training is a promising tool for newly organized hospital units’ staff. Objective: Our goal was to present the usefulness and applicability of virtual simulation exercises for training of field hospital personnel and to evaluate the adaptability of these created and tested exercise packs for urgent staff training of COVID-19 hospitals. Method: Three prototypes of virtual reality exercises were assessed through two test courses. XVR simulation software was used to create virtual environments. Evaluation of exercise applicability and utility was performed by anonymous questionnaires. Statistical data-processing was performed using contingency table and chi-square tests. Results: 76 trainees from eight countries participated in the two pilot courses. 63.9% of the participants stated that the method is suitable for conducting such exercises, but needs further development. Its technical use is “easy enough” to learn (59.7%) and provides an interactive (90.32%) and realistic (45.0%) working environment. Discussion: Virtual reality is applicable to train field hospital staffs for real missions. The created virtual exercise packages are easily adaptable, both in content and structure, to workshops dedicated for quick training of specific COVID-19 temporary medical facility’s personnel. Conclusion: Virtual reality is a promising educational tool that can complement the expensive and laborious field exercises, with comparable training efficiency. These virtual reality experiences may become real professional memories and create swiftly a secure and efficient professional milieu. Orv Hetil. 2021; 160(40): 1591–1600.

Virtual Reality (VR) seems a promising tool in lighting field, both for design and research applications. Despite several studies have been conducted on this topic, the opinions about the actual advantages of VR are conflicting. It is not clear if VR software are able to properly simulate spatial light distribution, and if the luminous sensation reproduced in Virtual Reality is representative of the real one. The paper revises the literature about the topic and then tests the reliability of a VR simulation software, Unreal Engine (UE), in calculating light. To do that, illuminance measurements were performed in a test room and the obtained values were compared with those calculated with both UE and DIVA for Rhinoceros. Results demonstrated that the percentage differences between the UE’s and the real values range from -2% to 5% and those between UE and DIVA from -4% to 0%.

: With the development of integrated circuits and microelectronics, integrated and miniaturized implantable medical devices are increasingly used in modern medical technologies, e.g., cardiac pacemakers, vasodilators, and cochlear implants. However, the normal operation of these devices is inseparable from the availability of a sufficient energy supply and the bidirectional transmission of internal and external signals. Due to the limitation of the working environment of sensors, there is only a small space for most implanted electronic devices, which is a challenge faced by existing technology. In this paper, current wireless implantable energy supply and communication technologies are reviewed to determine the best available technologies, thereby providing a reference for method selection in designing implantable medical systems.

Clinicians should appreciate the effectiveness of virtual reality (VR) headsets for managing both the anxiety and the behaviour of non-cooperative paediatric patients who require treatment over several dental appointments. The aim of this study was to assess the effectiveness of using a VR headset as a distraction for managing the anxiety and behaviour of paediatric patients during their dental treatment. Eighty patients, aged between five and ten years old and who required dental treatment over three or more appointments, were randomly allocated into two groups. One group used a VR headset during all their appointments, and the other one did not use any distraction technique. The patients were asked to take a Facial Image Scale Test during their first and last appointments to assess their level of anxiety. Additionally, the dentist completed the Frankl Test to quantify the child’s behaviour at the beginning and the end of their treatment. The results obtained, both from the group using the VR headset and from the control group, were compared using the chi-square test. The use of a VR headset during dental treatment significantly reduced anxiety (95% of the children were happy) and improved behaviour (100% positive behaviour) as compared with the control group (40% and 57.5%, respectively). A VR headset can effectively distract a paediatric patient, helping to reduce anxiety and manage behaviour during dental treatment

Introduction Opioid-induced constipation is a clinically relevant side effect and a cause of potentially avoidable drug-related hospital admissions. Objectives To describe the presence of laxative co-medication, the reasons for not starting laxatives and to evaluate changes in stool patterns of opioid initiators. Methods In this observational study community pharmacists evaluated the availability of laxative co-medication in starting opioid users and registered reasons for non-use. Two opioid initiators per pharmacy were invited to complete questionnaires (‘Bristol stool form scale’ and ‘Rome III Diagnostic Questionnaire for the Adult Functional Gastrointestinal Disorders’) on their defecation prior to and during opioid use. Descriptive statistics and Chi square tests were used to analyse reasons for non-use of laxatives and changes in defecation patterns. Results Eighty-one pharmacists collected data from 460 opioid initiators. Of those, 344 (74.8%) used laxatives concomitantly. Main reason not to use laxatives was that either prescribers or patients did not consider them necessary. Sixty-seven (89.3%) of the 75 opioid starters with two questionnaires completed were not constipated at opioid start. Eleven of them (16%) developed constipation during opioid use (Chi square p=0.003). At follow-up within laxative users 10.6% were constipated compared to 20.7% in subjects without laxatives. Conclusion One in four opioid starters did not dispose of laxative co-medication, mainly because they were not considered necessary by either the prescriber or the patient. The prevalence of constipation doubled during opioid use. A watchful waiting strategy for the use of laxative co-medication might include a monitoring of defecation patterns with validated questionnaires.

This study investigated the impact of labour turnover on organizational effectiveness in selected industries in Lagos State, Nigeria. This was with the view to determining the appropriate management strategies through which the problem of labour turnover could be reduced to the nearest minimum in work organizations in Nigeria. The survey research method was adopted for the study. A total of 640 respondents were selected for the study using proportionate stratified sampling technique. The major instruments used for the study were questionnaire and interview schedule. The reliability coefficient of 0.84 was obtained for the research instrument. The four hypotheses generated for the study were tested using chi-square and linear regression analysis statistical methods at 0.05 alpha levels. The findings of the study reveals that there was a significant relationship between labour turnover and organizational effectiveness. Also, a significant relationship was found dissatisfaction and labour turnover. There was a main effect of interaction of occupational variables and labour turnover on organizational effectiveness. Finally, a positive significant relationship was found among career mobility, labour turnover and organizational effectiveness. Based on the findings of the study, it is recommended that the working environment of the workers need to be improved upon in order to reduce the alarming rate of labour turnover that impact organizational effectiveness. Also, career development and promotion opportunities have become a rare phenomenon in most of the organisations, individuals who feel their contributions go unrewarded often feel undervalued which can lead to dissatisfaction and virtually an increase of unwarranted turnover. p>

Introduction: Psychiatric emergencies constitute between 1% - 10% of general emergencies in Spain, of which a quarter will end up being hospital admissions. There is little literature on patients who are referred from general to specialized hospitals. Methods: Cross-Sectional study of all the patients referred in 2018. Sociodemographic variables and clinical variables, such as diagnosis and discharge destination, were analyzed. An analysis was performed by comparing means with the Chi Square test. Results: 433 derived emergencies were analyzed. Most of the patients were women. The main reason for derivation were suicide attempts. Of those patients, 40% required hospitalizations. More than 50% of the derived emergencies were referred to the home and followed up on an outpatient basis. Conclusion: Most derived emergencies are referred to the home after evaluation. This implies that most are not life-threatening and that with adequate tools for evaluating suicide risk, we could avoid transfers and improve the resolution of these cases.

Background: Acute non-traumatic coma is a common problem in pediatric practice accounting for 10-15% of all hospital admissions and is associated with significant mortality. Assessment of the severity of coma is essential to comment on the likelihood of survival in comatose children. In the last three decades, various scores have been used to assess the severity of coma and to predict its outcome. Glasgow Coma Scale (MGCS) in spite of its various drawbacks has been widely used for assessing pediatric coma, though only few studies are available to support its use in pediatric coma as a whole. Hence the study was undertaken to evaluate the usefulness of coma scale in prediction of mortality in children between 1-12 years old admitted with coma of non-traumatic origin. Methods: A prospective study was conducted at Inpatient services of intensive medical care unit and general medical wards of Institute of child Health and Hospital for children, Egmore, Chennai, between October 2018 to November 2019. A Study Population consisting of children in the age group 1-12 years admitted in intensive care unit and medical wards with alteration in sensorium as one of the predominant complaints and admitted within 7 days of onset of coma were included. Sample size was 148. Chi-square test was used to study the association between the scores at Various times points and outcome. Results: It was observed that when the scores were between 3‐ 5 mortality rate was 67.0%, it was 17% when the minimal observed score was between 6-8. The group in which the minimal score never decreased be1ow 9 had no mortality. As the score increases the proportion of death decreases and the proportion having good recovery increases and vice versa. This type of association has been observed at different time points (Initial, 24 hrs, 48 hrs and 72 hrs). The significance of this association increases with the progression of time since admission. P value for the degree of association at various time points are: At presentation P < 0.00001, 24hrs - P < 0.000001, 48 hrs - P < 0.000001 and 72 hrs P < 0.00000001. Conclusion: There is highly statistically significant association between the GSC score levels and outcome. As the score increases the proportion of death decreases and the proportion having good recovery increases and vice versa.
