Acceptability and playability of an organization training videogame for young adolescents with ADHD: The development of ATHEMOS

An estimated 8.7% to 9.8% of school-age children in the United States have attention deficit hyperactivity disorder (ADHD), affecting 4.3 to 4.9 million public school students. ADHD is a costly disorder that often goes untreated, especially among adolescents. Accessible computer-based programs have emerged to address the neurocognitive deficits of ADHD, but results to date have been disappointing. In this study, we tested the acceptability, playability, and user satisfaction of a novel planning/organization skills training game, called "ATHEMOS," based on an established psychosocial treatment package (i.e., Challenging Horizons Program). We conducted eight focus groups during a three-year development period, using feedback from 72 young adolescents with ADHD to iteratively improve the game. Then, during a pilot study in the fourth year, we collected data from 16 young adolescents who played the game as part of a 6- to 16-week school-based intervention. Our findings suggest that the serious game resulted in acceptability and playability ratings only moderately below that of recreational games (δ = -0.40). Critically, average perceptions remained positive when delivered within a school-based ADHD intervention over several weeks or months, with strong overall user satisfaction. Boys found the game more acceptable than girls, with ratings near that of recreational games (δ = -0.23). We conclude that computer-assisted behavior interventions appeal to adolescents with ADHD and offer a potentially promising treatment delivery method in schools.

Uses and Considerations for Cinematic Virtual Reality in Health Care

BACKGROUND

Through the combination of virtual reality (VR) technology with techniques from theater, filmmaking, and gaming, individuals from the Game Research and Immersive Design Laboratory (GRID Lab) at Ohio University have developed an approach to train soft skills such as communication, problem-solving, teamwork, and interpersonal skills which shows great promise.

OBJECTIVES

The purpose of this article is to provide an overview of VR and cinematic-VR (cine-VR). This article serves as a preface to the VR research included in this special issue.

METHODS

In this article, we define VR, review key terminology, present a case study, and offer future directions.

RESULTS

Prior research with cine-VR has demonstrated the effectiveness in improving provider attitudes and cultural self-efficacy. While cine-VR may differ from other types of VR applications, we have been able to leverage the strengths of cine-VR to create training programs which are user friendly and highly effective. Early projects on diabetes care and opioid use disorder were sufficiently successful that the team received additional funding to pursue series addressing elder abuse/neglect and intimate partner violence. Their work has gone beyond health care and is currently being leveraged for law enforcement training as well. While this article will explore Ohio University's approach to cine-VR training, details of their research including efficacy can be found in McCalla et al, Wardian et al, and Beverly et al.

CONCLUSION

When produced correctly, cine-VR has the potential to become a mainstay component of training for soft skill applications across a multitude of industries.

Cinematic Virtual Reality for Educating Health Care Providers About Type 2 Diabetes, Disability, and Elder Abuse and Neglect: A Pilot Study

BACKGROUND

Diabetes care for older adults is complex and must consider geriatric syndromes, disability, and elder abuse and neglect. Health care providers would benefit from professional training programs that emphasize these risks. One new educational approach is cinematic virtual reality (cine-VR). We conducted a pilot study to evaluate a cine-VR training program based on an older patient with type 2 diabetes and multiple geriatric syndromes who is at risk for elder abuse and neglect.

METHODS

We employed a single-arm, pre-post-test study to assess changes in attitudes to disability and self-efficacy in identifying and managing elder abuse and neglect.

RESULTS

Thirty health care providers completed the pilot study (83.3% women, 86.7% white, 56.7% physicians, 43.4% practiced in outpatient clinics). We observed change in attitudes toward discrimination (Z = -2.628, P = .009, Cohen's d = .62). In addition, we observed changes in six of the eight self-efficacy items, including how participants would ask questions about abuse (Z = -3.221, P = .001, Cohen's d = .59) and helping an older patient make a report to the police or social services (Z = -2.087, P = .037, Cohen's d = .52). In addition, we observed positive changes in understanding the documentation needed to complete whether a patient reports abuse (Z = -3.598, P < .001) as well as the legal knowledge for how to report elder abuse and neglect (Z = -2.556, P = .011).

CONCLUSION

Findings from this pilot study suggest that cine-VR training may increase health care providers' awareness of discrimination and improve self-efficacy toward identifying and managing elder abuse and neglect. Research with a proper control condition is needed to confirm its effectiveness.

Using Virtual Reality to Improve Health Care Providers' Cultural Self-Efficacy and Diabetes Attitudes: Pilot Questionnaire Study

Background

In southeastern Appalachian Ohio, the prevalence of diabetes is 19.9%, nearly double that of the national average of 10.5%. Here, people with diabetes are more likely to have a delayed diagnosis, limited access to health care, and lower health literacy. Despite the high rates of diabetes in the region, the availability of endocrinologists and certified diabetes care and education specialists is limited. Therefore, innovative strategies to address the growing diabetes care demands are needed. One approach is to train the primary care workforce in new and emerging therapies for type 2 diabetes to meet the increasing demands and complexity of diabetes care.

Objective

The aim of this study was to assess the effectiveness of a virtual reality training program designed to improve cultural self-efficacy and diabetes attitudes.

Methods

Health care providers and administrators were recruited from large health care systems, private practices, university-owned hospitals or clinics, Federally Qualified Health Centers, local health departments, and AmeriCorps. Providers and administrators participated in a 3-hour virtual reality training program consisting of 360-degree videos produced in a professional, cinematic manner; this technique is called virtual reality cinema (cine-VR). Questionnaires measuring cultural self-efficacy, diabetes attitudes, and presence in cine-VR were administered to providers and administrators before and after the program.

Results

A total of 69 participants completed the study. The mean age of the sample was 42.2 years (SD 13.7), 86% (59/69) identified as female, 83% (57/69) identified as White, 86% (59/69) identified as providers, and 25% (17/69) identified as nurses. Following the training program, we observed positive improvements in all three of the cultural self-efficacy subscales: Cognitive (mean change –1.29; t₆₅=–9.309; P<.001), Practical (mean change –1.85; t₆₅=–9.319; P<.001), and Affective (mean change –0.75; t₆₅=–7.067; P<.001). We observed the largest magnitude of change with the subscale, with a Cohen d of 1.16 indicating a very large effect. In addition, we observed positive improvements in all five of the diabetes attitude subscales: Need for special training (mean change –0.21; t₆₇=–6.154; P<.001), Seriousness of type 2 diabetes (mean change –0.34; t₆₇=–8.114; P<.001), Value of tight glucose control (mean change –0.13; t₆₇=–3.029; P=.001), Psychosocial impact of diabetes (mean change –0.33; t₆₇=–6.610; P<.001), and Attitude toward patient autonomy (mean change –0.17; t₆₇=–3.889; P<.001). We observed the largest magnitude of change with the Psychosocial impact of diabetes subscale, with a Cohen d of 0.87 indicating a large effect. We observed only one significant correlation between presence in cine-VR (ie, Interface Quality) and a positive change score (ie, Affective self-efficacy) (r=.285; P=.03).

Conclusions

Our findings support the notion that cine-VR education is an innovative approach to improve cultural self-efficacy and diabetes attitudes among health care providers and administrators. The long-term impact of cine-VR education on cultural self-efficacy and diabetes attitudes needs to be determined.

Developing Virtual Reality Trauma Training Experiences Using 360-Degree Video: Tutorial

Historically, medical trainees were educated in the hospital on real patients. Over the last decade, there has been a shift to practicing skills through simulations with mannequins or patient actors. Virtual reality (VR), and in particular, the use of 360-degree video and audio (cineVR), is the next-generation advancement in medical simulation that has novel applications to augment clinical skill practice, empathy building, and team training. In this paper, we describe methods to design and develop a cineVR medical education curriculum for trauma care training using real patient care scenarios at an urban, safety-net hospital and Level 1 trauma center. The purpose of this publication is to detail the process of finding a cineVR production partner; choosing the camera perspectives; maintaining patient, provider, and staff privacy; ensuring data security; executing the cineVR production process; and building the curriculum.

Office ultrasound should be the first-line investigation for confirmation of correct ESSURE placement

BACKGROUND

Hysteroscopic options for permanent birth control (PBC), such as the ESSURE device, are becoming increasingly popular as an alternative to laparoscopic tubal ligation. The success of the technique hinges upon correct device placement within the intramural portion of the fallopian tube.

OBJECTIVE

To determine the utility of office ultrasound for confirming correct ESSURE PBC device placement at the 3-month check in a general gynaecology practice.

STUDY POPULATION

The first 99 patients in a single centre following ESSURE PBC device placement.

TYPE OF STUDY

Prospective cohort study.

METHODS

Clinical data was reviewed from patient records, both from the time of the initial procedure and from the follow-up at 3 months. All women underwent an ultrasound at the 3-month check.

RESULTS

The ESSURE PBC devices were placed successfully in 84.8% of cases. Of those cases with apparently successful placement, office ultrasound alone confirmed correct device placement at the 3-month check in 94% of cases. Further imaging was needed in only 6% of cases.

DISCUSSION

Office ultrasound performed by the general gynaecologist at the 3-month check is more convenient for the patient, and is sufficient to confirm ESSURE PBC device placement in the vast majority of cases. We propose that the protocol for ESSURE PBC device follow-up should be altered to replace X-ray with ultrasound as the first-line investigation.

Salvage mechanisms for regeneration of adenosine triphosphate in rat cardiac myocytes

Since mitochondrial oxidative phosphorylation does not produce sufficient adenosine triphosphate for rapid restoration of contractile function in myocardium reoxygenated after ischaemia alternative non-oxidative routes by which purine nucleosides or bases may be used to increase the cytoplasmic adenine nucleotide pool were studied. Comparative rates of uptake and salvage of adenosine, adenine, and hypoxanthine were determined using myocytes isolated from adult rat heart. For each precursor reactions limiting the overall rate at which substrate in the extracellular fluid is incorporated into the intracellular adenosine triphosphate pool were identified. Adenosine was salvaged at twice the rate seen with adenine in the presence of ribose, whereas the rate of salvage of hypoxanthine, in the presence of ribose, was only 5% of that for adenosine. Adenine may be an advantageous substrate since high concentrations of adenine are not inhibitory to salvage and do not influence cardiac haemodynamics. Salvage of hypoxanthine appeared to be limited by the rate of adenylosuccinate synthetase, which was present at less than 1% of the adenylosuccinase rate in rat, rabbit, and beef heart. In addition, since salvage of bases is dependent on the availability of phosphoribosylpyrophosphate rates of synthesis of phosphoribosylpyrophosphate were measured in whole myocytes from ribose and in cytoplasmic extracts from ribose and from ribose-5-phosphate. Metabolic sites were identified at which interventions designed to accelerate salvage rates might best be directed.

Calcium antagonists and adenine nucleotide metabolism in rat heart

Attempts to identify mechanisms by which calcium antagonists might influence intracellular metabolism have not yet yielded conclusive findings. In this study bepridil, verapamil, nifedipine, and nisoldipine were found to have no influence on the rate of rat heart myosin adenosine triphosphatase or the calcium dependence of myofibrillar adenosine triphosphatase. None of these calcium antagonists alters the rate of reaction of any of the adenine nucleotide catabolic or adenosine salvage enzymes, adenylate kinase, creatine kinase, adenosine kinase, adenosine deaminase, or 5' nucleotidase, in extracts of rat heart. All four compounds, however, reduced, apparently in a non-specific manner, the rate of uptake of adenosine by myocytes isolated from rat heart. It is concluded that calcium antagonists may, through intercalation with the sarcolemmal membrane, inhibit efflux of adenosine formed by catabolism of adenine nucleotides in ischaemic myocytes. This might offer therapeutic advantage since the intracellular concentration of adenosine would thereby be increased, allowing an increased rate of incorporation of adenosine into the adenosine triphosphate pool in reoxygenated myocardium.

Adenine nucleotide synthesis de novo in mature rat cardiac myocytes

Inadequate oxygenation of cardiac muscle leads to rapid loss of high energy compounds essential for contractile function. ATP can be regenerated by synthesis de novo, a route operating at a relatively slow rate in the heart. Myocytes isolated from mature rat heart have been used to measure the rate of ATP synthesis de novo from both [14C]glycine and [14C]ribose. Incorporation of glycine into ATP is accelerated 10-fold in the presence of 1 mM ribose. Myocytes also accumulate both precursors into IMP and four other metabolites on the de novo synthesis pathway. These metabolites represent 80% of the glycine entering the pathway. The potential of de novo synthesis for restoration of adenine nucleotides appears to be limited by the rates of early reactions, adenylosuccinate synthetase being only one of the enzymes operating at a sufficiently slow rate to make this pathway an inherently weak route for the restoration of normal energy status in post-ischemic myocardium. Interventions are being sought to alleviate these apparent metabolic delays.

Metabolism and salvage of adenine and hypoxanthine by myocytes isolated from mature rat heart

Adenine and hypoxanthine can be utilised by cardiac muscle cells as substrates for the synthesis of ATP. A possible therapeutic advantage of these compounds as high-energy precursors is their lack of vasoactive properties. Myocytes isolated from mature rat heart have been used to establish in kinetic detail the capacity of the heart to incorporate adenine, hypoxanthine and ribose into cellular nucleotides. Maximum rates of catalysis by enzymes on the salvage pathways have been established. Whilst the rate of incorporation of adenine into the ATP pool appears to depend upon intracellular concentrations of adenine and phosphoribosylpyrophosphate, for hypoxanthine the pattern is more complex. Hypoxanthine is salvaged at a slow rate compared with adenine, and is incorporated into GTP and IMP as well as into adenine nucleotides. The rate of incorporation of hypoxanthine into both IMP and ATP is accelerated in myocytes incubated with ribose. However, the rate-limiting reaction appears to be that catalysed by adenylosuccinate synthetase, for the rate of ATP synthesis is not accelerated when hypoxanthine concentration is increased from 10 to 50 microM, while the rate of IMP synthesis is more than doubled. Adenine and hypoxanthine phosphoribosyl transferases are present in equal catalytic amounts, but rat cardiac myocytes have very little adenylosuccinate synthetase activity. Exogenous ribose is incorporated into adenine nucleotides in amounts equimolar with adenine or hypoxanthine.

5'-Nucleotidase activity of isolated mature rat cardiac myocytes

Specific location of 5'-nucleotidase in the heart has been uncertain, some authors citing evidence for an exclusively non-myocyte location, while other data point to the existence of cytoplasmic and membrane-bound fractions. Single myocytes isolated from mature rat heart, and free of endothelial or interstitial cells, have been used to establish that muscle cells of the myocardium are rich in 5'-nucleotidase, exhibiting activity sufficient to account for the total myocardial content of this enzyme. All 5'-nucleotidase is accessible to extracellular AMP. Inhibitors of 5'-nucleotidase and adenosine transport have been used to establish that only the adenosine component of adenine nucleotides is taken up by myocytes, but hydrolysis of AMP by 5'-nucleotidase does not commit the adenosine formed to transport across the sarcolemmal membrane. Myocytes also have ecto-phosphatases which hydrolyse ADP and ATP.

Accumulation and salvage of adenosine and inosine by isolated mature cardiac myocytes

Reoxygenation of ischaemic, energy-depleted heart does not result in sufficiently rapid regeneration of normal adenine nucleotide concentrations for preservation of cardiac function and structure. Salvage of nucleoside as a mechanism for restoration of ATP in the post-ischaemic myocardium is limited by efflux of adenosine during ischaemia. Isolated cardiac myocytes have been used to establish the kinetics of uptake and salvage of adenosine and inosine, measuring the distribution of radioactive nucleoside incorporated into ATP, ADP and AMP. Maximum rates of catalysis of reactions on the salvage pathway, and of enzymes competing for substrates on the pathway, have been established in myocyte extracts. Myocytes have little capacity to salvage or catabolise inosine. Enzyme measurements indicate that salvage of adenosine should proceed at 7-8-times the rate exhibited by intact myocytes dependent upon extracellular adenosine as substrate. The data indicate that the rate of transport of adenosine is not determined by its metabolic utilization, but is the rate-limiting step in the salvage of adenosine.
