Extended reality (XR) technologies such as virtual reality (VR) provide a promising alternative for training users through serious games (SGs). VR SGs allow people to train in emergency scenarios and improve their likelihood of survival in high-risk situations. Studies have shown that incorporating design elements such as wayfinding cues enhances the spatial knowledge of users in VR. However, the impact of these wayfinding cues on users’ psychological and psychometric behaviors needs thorough investigation. An SG was designed to investigate wayfinding cues’ psychological and psychometric effects on user-perceived experiences in an immersive VR environment. Thirty-nine participants experienced three variants of the VR SG using Oculus Rift- S. Participants in the control condition were exposed to the VR with no wayfinding cues, and the experimental groups were exposed to VR with static and dynamic wayfinding cues. Results showed that VR SG with wayfinding cues induced less tension, challenge, and negative affects in users’ overall perceived experience. Similarly higher positive affects were observed for the experimental groups with wayfinding cues. It was interesting to observe that there were no significant effects of wayfinding on competence, flow, and immersion; however, heart rate was significantly high in the control group. These findings suggest that wayfinding cues can promote the users perceived quality of experience in the VR.

Abstract Background Hearing loss is quite prevalent and can be related to people’s quality of life. To our knowledge, there are limited studies assessing the efficacy of hearing interventions on quality of life in adults. Therefore, we aim to conduct a randomized controlled trial (RCT) to determine the impact and cost-effectiveness of community-based hearing rehabilitation on quality of life among Chinese adults with hearing loss. Methods/design In this two-arm feasibility study, participants aged 16 and above with some degree of hearing loss (n = 464) will be recruited from Linyi City, Shandong Province. They are randomly assigned to the treatment group or the control group. Those in the treatment group are prescribed with hearing aids, while those in the control group receive no intervention. Reinstruction in use of devices is provided for the treatment group during booster visits held 12 months post-randomization or unscheduled interim visits when necessary. Data are collected at baseline and the follow-up 20 months later. The primary outcome is changes in quality of life over a 20-month study period. Secondary outcomes include sub-dimensions in quality of life, physical functioning, chronic diseases, cognitive function, depression, social support, hospitalizations, falls, and healthcare costs. Finally, we will evaluate whether hearing aids intervention is cost-effective to apply in a large scale. Discussion The trial is designed to evaluate the impact and cost-effectiveness of a community-based rehabilitation intervention on quality of life among Chinese adults with hearing loss. We hope that it would help improve the well-being for Chinese adults and provide references in policy and practice for China and other countries.

Objective Explore the impact of personalized nursing services and hospice care on the quality of life of elderly patients with advanced cancer. Method We selected 80 elderly cancer patients admitted to our hospital from September 2020 to May 2021, and divided these patients into a study group and a control group using a random number table method. The patients in the control group used conventional nursing methods to treat and care for the patients, and the patients in the study group used hospice care measures and combined personalized nursing measures. The quality of life and pain treatment effects of the two groups of patients before and after treatment were compared. Result Before treatment, the quality-of-life scores of the two groups of patients were low, and there was no statistical difference (P>0.05); After treatment, the quality of life of the two groups of patients improved, but compared with the control group, the improvement was more obvious in the study group, and the difference was statistically significant (P<0.05). In terms of pain treatment effect, the total effective rate of pain treatment in the study group was 87.5%, which was significantly better than the 62.5% in the control group. The difference was statistically significant (P<0.05). Conclusion Personalized nursing services and hospice care are conducive to improving the survival and treatment of elderly patients with advanced cancer, and can be used as a clinical application program for the care of advanced cancer patients.

BACKGROUND Strong evidence supports beginning stroke rehabilitation as soon as the patient’s medical status has stabilized and continuing following discharge from acute care. However, adherence to rehabilitation treatments over the rehabilitation phase has been shown to be suboptimal. OBJECTIVE Objective: The aim of this study is to assess the impact of a telerehabilitation platform on stroke patients’ adherence to a rehabilitation plan and on their level of reintegration to normal social activities, in comparison with usual care. The primary outcome is patient adherence to stroke rehabilitation (up to 12 weeks), which is hypothesized to influence reintegration to normal living. Secondary outcomes for patients include functional recovery and independence, depression, adverse events related to telerehabilitation, use of services (up to 6 months), perception of interprofessional shared decision making, and quality of services received. Interprofessional collaboration as well as quality of interprofessional shared decision making will be measured on clinicians. METHODS In this interrupted time series with a convergent qualitative component, rehabilitation teams will be trained to develop rehabilitation treatment plans that engage the patient and family, while taking advantage of a telerehabilitation platform to deliver the treatment. The intervention will entail 220 patients to receive stroke telerehabilitation with an interdisciplinary group of clinicians (telerehabilitation) versus face-to-face, standard of care (n = 110 patients). RESULTS Results: Our Research Ethics Board has approved the study in June 2020. Data collection for the control group is underway, with another year planned before we begin the intervention phase. CONCLUSIONS This study will contribute to minimize both knowledge and practice gaps, while producing robust, in-depth data on the factors related to the effectiveness of telerehabilitation in a stroke rehabilitation continuum. Findings will inform best practices guidelines regarding telecare services and the provision of telerehabilitation, including recommendations regarding effective interdisciplinary collaboration regarding stroke rehabilitation.

Abstract Risk factors for long-term non-motor disorders and quality of life following subthalamic nucleus deep-brain stimulation (STN DBS) have not yet been fully identified. In the present study, we investigated the impact of motor symptom asymmetry in Parkinson’s disease.Data were extracted for 52 patients with Parkinson’s disease (half with left-sided motor symptoms and half with right-sided ones) who underwent bilateral STN and a matched healthy control group. Performances for cognitive tests and neuropsychiatric and quality-of-life questionnaires at 12 months post-DBS were compared with a pre-DBS baseline. Results indicated a deterioration in cognitive performance post-DBS in patients with left-sided motor symptoms. Performances of patients with right-sided motor symptoms were maintained, except for a verbal executive task. These differential effects had an impact on patients’ quality of life. The results highlight the existence of two distinct cognitive profiles of Parkinson’s disease, depending on motor symptom asymmetry. This asymmetry is a potential risk factor for non-motor adverse effects following STN DBS.

The article presents the results of studying the impact of the spore-forming probiotic “Olin” and the prebiotic “Eсofiltrum” on the meat quality of broiler chicken carcasses of the Ross-308 cross. In the course of the research, it has been found that the inclusion of these preparations in the broiler diet has a positive effect on the studied indicators: the pre-slaughter weight increased by 4.3-5.7%, the weight of the gutted carcass by 4.6-6.2%, the muscle weight 4.8-6.5%, the weight of the loin muscles by 5.7-8.2%. The ratio of edible parts to inedible parts is 4.14 in the third experimental group, 4.08-in the second, and 4.04-in the control. Based on the results of the anatomical cutting of broiler carcasses and according to the fatness indicators the poultry carcasses of the third and second experimental groups, 87.5% and 87.2%, respectively, belong to the first grade, and the yield of the first grade carcasses is 86.2% in the control group. Meat products obtained from both the control poultry and the poultry of both experimental groups has no off-aroma odor and taste, the meat is juicy, tender and aromatic. The products obtained from broiler chickens, whose ration includes the probiotic “Olin” and the prebiotic “Ecofiltrum”, do not have any deviations from the established standards and norms. During the research, it has been found that the use of the studied drugs has a positive effect on the meat quality of poultry carcasses. However, broiler chickens receiving the probiotic “Olin” has more pronounced meat qualities.

IntroductionIntervention with informal caregivers (IC) of psychiatric patients is internationally recognized as relevant and a priority. However, the existing responses in this area are still insufficient, especially regarding caregivers of individuals with mood disorders (MD). Mindfulness and compassion focused therapy have proven to be an effective approach in stress reduction and in improving emotional and social well-being of caregivers of patients with other conditions. However, no studies testing these new approaches in IC of patients with MD have been carried out. The objective of this work is to present a research project that aims to develop, implement and empirically test the effectiveness of an innovative group program to help informal caregivers of individuals with mood disorders to cope with the negative impact of the disease and reduce caregiver burdens.MethodsThe design of this experimental study to test the program's efficacy is a non-randomised controlled trial (nrct) with 12 months follow-up, with a mixed assessment methodology (quantitative and qualitative analysis). A sample of 60 informal caregivers of individuals with chronic MD will be constituted (n = 30 Control group; n= 30 Experimental group).ResultsWe expect the program to promote significant changes in participants in terms of several emotional variables (eg: burden, stress, resilience, compassion and quality of life).ConclusionsFurther efforts to continue studying the impact of interventions in caregivers should be carried out, as a way to improve the quality of life of caregivers and their ability to provide informal care to MD patients.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Radiologic technologists face various types of patients during multi-detector computed tomography (CT) examinations. In emergency departments, it is common to have patients who cannot follow instructions for the examinations. The asymmetric axial view of the head CT might affect the correctness of the clinician’s diagnosis. This study aimed to assess the impact of head positioning on the image quality of head CT using two phantoms. All scans were performed on a 16-slice CT scanner. In the control group, the tilted angle of the phantoms was 0[Formula: see text], and no multiplanar reconstruction (MPR) was performed. In the experimental groups, the tilted angles of the phantoms were 5[Formula: see text], 10[Formula: see text] and 15[Formula: see text], respectively, and MPR was performed afterwards. The results showed that if the head was tilted during the head CT examinations, image asymmetry and artifacts appeared without MPR. After MPR, one phantom showed that there were significant differences and the other phantom showed no significant differences quantitatively in image symmetry and artifacts between experimental groups and the control group, while both phantoms showed no significant differences qualitatively in image symmetry and artifacts between experimental groups and the control group. Although MPR can correct the image asymmetry and artifacts caused by tilted head positioning to some extent, it consumes time. Therefore, technologists should position the head as exactly as possible when performing head CT examinations.

BACKGROUND The COVID-19 Pandemic led to drastic increases in the prevalence and severity of insomnia symptoms. These increases in insomnia complaints have been paralleled by significant decreases in well-being, including increased symptoms of depression, anxiety, and suicidality and decreased quality of life. However, the efficacy and impact of early treatment of insomnia symptoms on future sleep and well-being remains unknown. OBJECTIVE Here, we present the framework and protocol for a novel study that aims to investigate whether a brief telehealth insomnia intervention targeting new insomnia that developed during the pandemic prevents deterioration of well-being, including symptoms of insomnia, depression, anxiety, suicidality, and quality of life. METHODS The protocol details a two-arm randomized controlled trial to investigate the efficacy of a brief, telehealth-delivered, early treatment of insomnia and evaluate its potential to prevent a deterioration of well-being. Participants with clinically significant insomnia symptoms that began during the pandemic are randomized to either a treatment group or a 28-week waitlist control group. Treatment consists of 4 telehealth sessions of Cognitive Behavioral Therapy for Insomnia (CBT-I) delivered over 5 weeks. All participants will complete assessments of insomnia symptom severity, well-being, and daily habits checklist at baseline (week 0), and at weeks 1-6, 12, 28, and 56. RESULTS The trial began enrollment June 3, 2020 and closed enrollment June 17, 2021. As of October 2021, 49 participants have been randomized to either immediate treatment or a 28-week waitlist. 23 participants are still active in the protocol. CONCLUSIONS To our knowledge, this protocol would be represent the first study to test an early sleep intervention for improving insomnia that emerged during the COVID-19 Pandemic. The findings of this study could provide information about the utility of CBT-I for symptoms that emerge in the context of other stressors before they develop a chronic course and deepen understanding of the relationship between sleep and well-being.

SSIs after ventral hernia repair (VHR) represent a significant complication. The impact of postoperative prophylactic antibiotics on the SSI rates after VHRs is unclear. A systematic review of PubMed and Web of Science databases from inception through March 2016 investigating the effect of postoperative prophylactic antibiotics after VHRs was performed. Strict inclusion and exclusion criteria were implemented, and the methodological quality of the included studies was assessed. After systematic independent assessment of 216 citations, four studies, involving 344 patients, met the inclusion criteria. Among the included studies, 164 patients received >24 hours of postoperative prophylactic antibiotics, whereas 180 patients were controls. The overall incidence of SSI among patients receiving postoperative antibiotics was 14.6 per cent (95% confidence interval [CI], 9.9 to 20.9) which compares favorably with the control group: 35.5 per cent (95% CI, 28.9 to 42.7) (odds ratio: 0.3, 95% CI: 0.2 to 0.5, P < 0.01). Among patient's receiving postoperative antibiotics, the pooled average duration of postoperative antibiotic treatment was 6.2 ± 0.4 days. Based on the available evidence, the use of postoperative prophylactic antibiotics seems to be associated with lower SSI rates after VHRs. Future prospective randomized controlled trials should be conducted to further confirm the efficacy of this prophylactic intervention.
