Automation Use and Dis-Use in Golf: The Impact of Distance Measuring Devices on Trust in Technology and Confidence in Determining Distance.

An athlete's decision to use technology depends on trust in the automation, and confidence in their abilities. Distance measuring devices (DMD) are used in golf to estimate yardage. The purpose of these studies was to examine how DMD usage affects trust in the DMD, confidence in determining yardage manually, and golf performance over time. In study 1, DMD non-users played four rounds of golf, two with the DMD and two without. In study 2, DMD users played five rounds, three with the device, and two without. Participants' trust in automation, confidence, and performance were recorded by online survey at baseline and following each round. Giving a DMD to non-users influenced trust in automation and confidence. When DMD users relinquished the device, confidence decreased briefly but rebounded quickly, trust in automation was unaffected. Performance was unchanged in both groups. These studies provide information about how confidence in abilities and trust in automation interact.

What do people hospitalised with COVID-19 think about their care? Results of a satisfaction survey during the first wave of COVID-19 in Liverpool.

Despite huge advances in vaccines, testing and treatments for COVID-19, there is negligible evidence on the perceptions of people hospitalised with COVID-19 about the care they received. To address this, we developed a satisfaction survey for people with COVID-19 admitted to our hospital during the first COVID-19 wave in Liverpool. Of those invited, 98/160 (61%) responded, of whom 94/98 (96%) completed the survey. Respondents rated overall care highly (mean 4.7/5) and 89/94 (95%) reported that they would recommend the hospital to friends and/or family. Most respondents felt safe on the ward (94%), with privacy maintained (93%) and pain well managed (90%). Fewer than two-thirds (63%) of respondents considered themselves adequately consulted regarding medications and side effects. Sleep and food/drink quality were also highlighted as areas for improvement. To overcome the issues raised, we generated a 'COVID-19 practice pointers' poster within an integrated educational bundle on COVID-19 wards. The impact of the bundle on perceptions of people hospitalised with COVID-19 will be evaluated in people hospitalised with COVID-19 in Liverpool in 2021. Whether hospitalised for COVID-19 or other conditions, our survey results are a timely reminder of the importance of involving patients in shaping the care that they receive.

Privacy-first health research with federated learning.

Privacy protection is paramount in conducting health research. However, studies often rely on data stored in a centralized repository, where analysis is done with full access to the sensitive underlying content. Recent advances in federated learning enable building complex machine-learned models that are trained in a distributed fashion. These techniques facilitate the calculation of research study endpoints such that private data never leaves a given device or healthcare system. We show-on a diverse set of single and multi-site health studies-that federated models can achieve similar accuracy, precision, and generalizability, and lead to the same interpretation as standard centralized statistical models while achieving considerably stronger privacy protections and without significantly raising computational costs. This work is the first to apply modern and general federated learning methods that explicitly incorporate differential privacy to clinical and epidemiological research-across a spectrum of units of federation, model architectures, complexity of learning tasks and diseases. As a result, it enables health research participants to remain in control of their data and still contribute to advancing science-aspects that used to be at odds with each other.

Sleep-disordered breathing is increased in obese adolescents with craniopharyngioma compared with obese controls.

CONTEXT: Retrospective studies suggest that adolescents with craniopharyngioma and hypothalamic obesity have increased sleep-disordered breathing (SDB). OBJECTIVES: The objectives of this study were to compare the prevalence of SDB in adolescents with craniopharyngioma-related obesity compared with body mass index (BMI)-matched controls and to explore possible relationships between SDB, insulin resistance, and adipocytokines. DESIGN: This was a cross-sectional study of obese craniopharyngioma and obese control adolescents. SETTING: Subjects were evaluated in the clinical investigation unit at the Hospital for Sick Children, Toronto. PATIENTS: Fifteen patients with craniopharyngioma-related obesity and 15 BMI-matched controls were recruited and tested. INTERVENTIONS: Each subject underwent fasting blood work, frequent sampled iv glucose tolerance test, polysomnography, and abdominal magnetic resonance imaging with calculation of visceral and sc adipose tissue. MAIN OUTCOME MEASURES: Main measures included insulin sensitivity, sleep efficiency, and fragmentation. RESULTS: Insulin sensitivity was lower in craniopharyngioma subjects compared with control subjects (0.96 +/- 0.34 vs. 1.67 +/- 0.7, P = 0.01). Sleep-onset latency (19.3 +/- 27.8 vs. 31.9 +/- 23.4, P = 0.03) and oxygen saturations (rapid eye movement sleep: 89.0 +/- 5.1 vs. 94.2 +/- 2.3, P < 0.001; non-rapid eye movement sleep: 88.4 +/- 5.6 vs. 94.3 +/- 1.5, P < 0.001) were lower in craniopharyngioma. Obstructive apnea-hypopnea index (OAHI) (7.5 +/- 9.0 vs. 1.5 +/- 1.5, P = 0.03) was higher in craniopharyngioma. Respiratory distress index and OAHI correlated negatively with adiponectin concentrations (r = -0.61, P = 0.03, r = -0.71, P = 0.006, respectively) in craniopharyngioma. On multiple regression, TNF-alpha and craniopharyngioma were independent positive predictors of sleep-onset latency and adiponectin and craniopharyngioma were significant predictors (negative and positive, respectively) of OAHI. CONCLUSIONS: SDB is increased in adolescents with craniopharyngioma-related obesity compared with BMI-matched controls. Routine polysomnography should be considered in obese patients with craniopharyngioma and appropriate treatment initiated.
