Objectives Canada has one of the highest age-adjusted incidence and prevalence rates of inflammatory bowel disease (IBD). Large patient volumes and limited resources have created challenges concerning the quality of IBD care, but little is known about patients’ experiences. This paper aimed to better understand patient-perceived barriers to IBD care. Methods An exploratory qualitative approach was used for this study. Fourteen focus groups (with 63 total participants) were co-facilitated by a researcher and patient research partner across eight Canadian provinces in 2018. Patients diagnosed with IBD (>18 years of age) and their caregivers were purposefully recruited through Crohn’s and Colitis Canada, gastroenterology clinics and communities, and national social media campaigns. Focus group sessions were recorded, transcribed, and analyzed using thematic analysis. Results Most participants self-identified as being white and women. The analysis generated four key themes regarding patient-perceived barriers and gaps in access to IBD care: (1) gatekeepers and their lack of IBD knowledge, (2) expenses and time, (3) lack of holistic care, and (4) care that is not patient-centered. An additional four themes were generated on the topic of patient-perceived areas of health system improvement for IBD care: (1) direct access to care, (2) good care providers, (3) electronic records and passports, and (4) multidisciplinary care or an ‘IBD dream team’. Conclusions This research contributes to the limited global knowledge on patients’ experiences accessing IBD care. It is valuable for the development of care plans and policies to target gaps in care. Patients have identified system-level barriers and ideas for improvement, which should be taken into consideration when implementing system redesign and policy change.

Introduction In recent years, injury insurers in Australia have introduced compensation cover for services delivered via telehealth. The aim of this study was to investigate the uptake of telehealth services by people recovering from road trauma in Victoria, Australia, and the characteristics of participants accessing these services. Methods All Victorian State Trauma Registry and Victorian Orthopaedic Trauma Outcomes Registry cases, aged ≥16 years, who sustained transport-related injury from March to August 2020, and were linked with the Transport Accident Commission claims dataset, were included in this registry-based cohort study. The primary outcome was the uptake of services accessed in-person and via telehealth. Results Within 12 months of injury, 413 participants accessed 93,035 services, with 1432 of these via telehealth (1.5%). Seventy-five percent of family counselling, 26% of psychology and 7% of medical consultations were accessed via telehealth. For telehealth users, a greater proportion had worked/studied prior to injury, met major trauma criteria, and were discharged to inpatient rehabilitation, compared to non-users. For participants with no telehealth use, a greater proportion were discharged home, and were classified as ‘rapid recovery’ clients. Conclusions While telehealth uptake was low during the study period, it was accessed by people with more severe injuries. There was also greater telehealth uptake during some of Victoria's strictest COVID-19 lockdowns. Telehealth may continue to be an appealing option for medical and psychological services into the future, and may assist with return to work following transport injury.

Purpose The contour neurovascular system (CNS) is an intrasaccular flow-disrupting device designed for the treatment of intracranial wide-necked bifurcation aneurysms. Metal artifacts limit magnetic resonance imaging (MRI) accessibility after implantation. The purpose of this in vitro study was to evaluate non-invasive imaging alternatives to digital subtraction angiography (DSA). Material and methods Three aneurysms of patients originally treated with CNS were three-dimensional (3D)-printed (one at the basilar tip and two at the middle cerebral artery bifurcation). CNS devices were implanted under fluoroscopic control into the 3D models. Post-implantation two-dimensional-DSA, flat panel computed tomography angiography (CTA), MRI, and spectral CTA were performed. Results Time of flight angiography and T1 weighted sequences showed large susceptibility artifacts at the detachment zone of the devices. A thin-sliced T2 weighted sequence in cross-sectional orientation to the aneurysm allowed visualization of the aneurysm dome, but the aneurysm neck and parent vessel could not be assessed. Focused spectral CTA, especially a 40 keV reconstruction with a metal artifact reduction algorithm (orthopedic metal artifact reduction (OMAR)), showed only minor artifacts at the detachment zone. This approach achieved a very similar result to DSA and flat panel computed tomography, enabling the assessment of the device structure, aneurysm perfusion, and parent vessel perfusion. Discussion and conclusion For non-invasive follow-up of CNS, focused 40 keV CTA with OMAR seems to be a valuable option. MRI can be valuable for larger aneurysms to assess the aneurysm dome, but was not suitable for evaluating the parent vessels and aneurysm neck after CNS implantation in this study.

Background Delayed cerebral ischemia (DCI) following aneurysmal subarachnoid hemorrhage (aSAH) is associated with adverse neurological outcomes. Early and accurate diagnosis of DCI is crucial to prevent cerebral infarction. This study aimed to assess the diagnostic accuracy and interrater agreement of the visual assessment of neuroimaging perfusion maps to detect DCI in patients suspected of vasospasm after aSAH. Methods In this case-control study, cases were adult aSAH patients with DCI who underwent magnetic resonance perfusion or computed tomography perfusion (CTP) imaging in the 24 h prior to digital subtraction angiography for vasospasm diagnosis. Controls were patients with dizziness and no aSAH on CTP imaging. Three independent raters, blinded to patients’ clinical information, other neuroimaging studies, and angiographic results, visually assessed anonymized perfusion color maps to classify patients as either having DCI or not. Tmax delay was classified by symmetry into no delay, unilateral, or bilateral. Results Perfusion imaging of 54 patients with aSAH and 119 control patients without aSAH was assessed. Sensitivities for DCI diagnosis ranged from 0.65 to 0.78, and specificities ranged from 0.70 to 0.87, with interrater agreement ranging from 0.60 (moderate) to 0.68 (substantial). Conclusion Visual assessment of perfusion color maps demonstrated moderate to substantial accuracy in diagnosing DCI in aSAH patients.

Background Scrub typhus is an acute febrile infectious disease highly prevalent in the Asia Pacific region, often referred to as the “tsutsugamushi triangle.” This mite-borne rickettsial zoonosis is caused by Orientia tsutsugamushi, an intracellular Gram-negative organism that primarily targets endothelial cells. The resulting vasculitis leads to multisystem involvement. In terms of neurological manifestations, meningoencephalitis is the most common presentation of scrub typhus. Other frequent neurological manifestations include cranial nerve paresis, transverse myelitis, and polyneuropathy. Status epilepticus, while reported, is a rare presenting feature of this infection. Although scrub typhus has been documented to present as limbic encephalitis, there have been no previous descriptions in the literature of neuroradiological patterns affecting the basal ganglia or extra-limbic cortices in this condition. Case Report We report a case of a 23-year-old previously healthy woman who presented with scrub typhus meningoencephalitis. The condition manifested as encephalitis with involvement of the basal ganglia and extra-limbic cortices. She presented with generalized convulsive status epilepticus, which was complicated by cortical multifocal myoclonus. Discussion Scrub typhus can be a significant diagnostic challenge, potentially presenting with generalized convulsive status epilepticus and mimicking both clinical and radiological features of arboviral encephalitides, such as those caused by West Nile and Japanese encephalitis viruses. Furthermore, as demonstrated in this case, its radiological presentation can resemble that of autoimmune encephalitis. Given that scrub typhus is amenable to treatment with antibiotics, such as doxycycline and azithromycin, which do not increase seizure risk, it should be considered in the differential diagnosis for patients presenting with seizures or encephalitis, especially in endemic areas.

Background: Recombinant porcine factor VIII (rpFVIII; susoctocog alfa) is indicated for the treatment of bleeding events (BEs) in adults with acquired hemophilia A (AHA). Objectives: To assess the safety, utilization, and effectiveness of rpFVIII in clinical practice. Design: EU post-authorization safety study (PASS) (NCT03199794) was a multicenter, noninterventional, post-authorization safety study conducted in adults with AHA. Methods: Data were collected retrospectively or prospectively for up to 180 days after the last rpFVIII dose. The primary objective was safety, as assessed by adverse events (AEs), serious AEs (SAEs), and AEs of special interest (AESIs) (e.g. immunogenicity, hypersensitivity reactions, thromboembolic events). Secondary endpoints included immunogenicity, rpFVIII hemostatic effectiveness, and rpFVIII utilization. Results: Fifty patients were enrolled; 31 completed the study. The median (range) follow-up for patients who completed or discontinued the study was 178 (26–371) days. The median (range) first dose of rpFVIII was 54.0 (11–200) U/kg. Thirty patients reported 46 SAEs; 5 SAEs were considered probably related to rpFVIII, of which 1 was lack of rpFVIII efficacy, and 4 were AESIs: drug resistance due to FVIII inhibition (one patient), antibody test positive for anti-pFVIII inhibitors (one patient), and de novo anti-pFVIII inhibitors (two patients). No hypersensitivity reactions or thromboembolic events were reported. Of the 50 initial BEs, 37 resolved [in a median (interquartile range) of 8.0 (4.0–16.0) days]. Conclusion: Results from this real-world study support the use of rpFVIII for AHA, aligning with findings from the clinical trial of rpFVIII (NCT01178294) in the treatment of BEs in adults with AHA. Trial registration: EUPAS16055; NCT03199794.

Introduction ChatGPT can serve as an adjunct informational tool for ophthalmologists and their patients. However, the reliability and readability of its responses to myopia-related queries in the Chinese language remain underexplored. Purpose This study aimed to evaluate the ability of ChatGPT to address frequently asked questions (FAQs) about myopia by parents and caregivers. Method Myopia-related FAQs were input three times into fresh ChatGPT sessions, and the responses were evaluated by 10 ophthalmologists using a Likert scale for appropriateness, usability, and clarity. The Chinese Readability Index Explorer (CRIE) was used to evaluate the readability of each response. Inter-rater reliability among the reviewers was examined using Cohen's kappa coefficient, and Spearman's rank correlation analysis and one-way analysis of variance were used to investigate the relationship between CRIE scores and each criterion. Results Forty-five percent of the responses of ChatGPT in Chinese language were appropriate and usable and only 35% met all the set criteria. The CRIE scores for 20 ChatGPT responses ranged from 7.29 to 12.09, indicating that the readability level was equivalent to a middle-to-high school level. Responses about the treatment efficacy and side effects were deficient for all three criteria. Conclusions The performance of ChatGPT in addressing pediatric myopia-related questions is currently suboptimal. As parents increasingly utilize digital resources to obtain health information, it has become crucial for eye care professionals to familiarize themselves with artificial intelligence-driven information on pediatric myopia.

Abstract
Purpose
The purpose of this study was to assess the association between antifungal susceptibility as measured by minimum inhibitory concentration (MIC) and clinical outcomes in fungal keratitis.

Methods
This pre-specified secondary analysis of the Mycotic Ulcer Treatment Trial II (MUTT II) involved patients with filamentous fungal keratitis presenting to Aravind Eye Hospitals in South India. Antifungal susceptibility testing for natamycin and voriconazole was performed on all samples with positive fungal culture results according to Clinical and Laboratory Standards Institute Guidelines. The relationship between MIC and clinical outcomes of best-corrected visual acuity, infiltrate or scar size, corneal perforation, need for therapeutic penetrating keratoplasty, and time to re-epithelialization were assessed.

Results
We obtained MIC values from 141 patients with fungal keratitis. The most commonly cultured organisms were Aspergillus (46.81%, n = 66) and Fusarium (44.68%, n = 63) species. Overall, there was no association between antifungal MICs and clinical outcomes. Subgroup analysis revealed that among Fusarium-positive cases, higher voriconazole MIC was correlated with worse three-month best-corrected visual acuity (p = 0.03), increased need for therapeutic penetrating keratoplasty (p = 0.04), and time to re-epithelialization (p = 0.03). No significant correlations were found among Aspergillus-positive cases. There were no significant correlations found between natamycin MIC and clinical outcomes among organism subgroups.

Conclusions
Decreased susceptibility to voriconazole was associated with increased odds of requiring a therapeutic penetrating keratoplasty in Fusarium-positive cases. Susceptibility to natamycin was not associated with any of the measured outcomes.

Abstract
Background
Primary hypogonadism is a recognised complication in survivors of testicular cancer. However, secondary hypogonadism can result from other causes that suppress the hypothalamic-pituitary axis, including obesity, high dose glucocorticoids, chronic end organ failure, and diabetes. The aim of this study was to explore low total serum testosterone in Australian survivors of testicular cancer and examine associations with body mass index, age, and prior chemotherapy use.

Methods
Clinical data including height, weight, diagnosis, treatment, and hormonal evaluations during follow-up were extracted from the Australian and New Zealand Urogenital and Prostate (ANZUP) Cancer Trials Group Chemocog study (2007-2012), accompanied by data from two Australian, high-volume testicular cancer centres included in the iTestis testicular cancer registry (2012-2019). Low testosterone was defined by a serum concentration of testosterone (T) < 10 nmol/L, and was classified as primary by a serum concentration of luteinising hormone (LH) > 8 IU/L, otherwise as secondary.

Results
Two hundred eighty-five individuals with either stage 1 or advanced testicular cancer were included. Of these, 105 (37%) were treated with orchidectomy and chemotherapy. Forty-nine (17%) met criteria for low testosterone during follow-up: 21 (43%) had primary and 27 (55%) had secondary low testosterone. Survivors of testicular cancer with higher body mass index were more likely to display low testosterone, both primary (p = 0.032) and secondary (p = 0.028). Our data did not show evidence of an association between older age or chemotherapy use and low testosterone in our cohort.

Conclusions
Low total serum testosterone was common in survivors of testicular cancer, and associated with a higher body mass index prior to orchidectomy, suggesting that elevated body mass index may contribute to low testosterone in this population, and that body weight, diet, and exercise should be addressed in testicular cancer follow-up.
Interactions during falls with environmental objects: evidence from real-life falls in long-term care captured on video

Published: September 2024

Abstract
Background
Falls are the leading cause of injuries in older adults. Environmental objects (such as furniture, walls, and handrails) may act as hazards or facilitators to balance maintenance and safe landing. There is lack of objective evidence on how older adults interact with objects during falls. We addressed this gap by characterizing body part contacts with objects other than the floor during real-life falls in long-term care.

Methods
We analyzed videos of 1759 falls experienced by 584 residents to characterize the prevalence of contacts with objects before, during, and after fall initiation. Using generalized estimating equations, we compared the prevalence of falls with versus without contact to objects after fall initiation. Using linear mixed models, we tested for differences across body parts in the probability of contacting objects after fall initiation.

Results
In nearly one-third of falls, interactions with objects (e.g., trips over objects, loss of support with objects) or with other people (e.g., being pushed by another person) had a primary role in causing imbalance and initiating the fall. After fall initiation, participants contacted objects in 60% of falls, with intentional hand contacts to objects via reach-to-grasp or bracing being the most common type of interaction (Probability ± SE = 0.32 ± 0.01), followed by unintentional impacts to the torso (0.21 ± 0.01) and head (0.16 ± 0.01). Intentional hand contact to an object was more common during forward than backward falls (p < 0.001), while head and torso contacts to objects were more common during backward and sideways falls than forward falls (multiple p values ≤ 0.003). The hand most often contacted chairs, wheelchairs or couches, followed by tables or counters, walls, other people, walkers, and handrails. The head, torso, and shoulder most often contacted a wall.

Conclusions
Most falls in long-term care involved contacts with objects other than the ground, indicating that complex environments often accompany falls in long-term care. Higher probabilities of intentional hand contacts in forward falls, versus unintentional head and torso impacts in backward and sideways falls may reflect the influence of being able to visualize and adjust one’s falling patterns to nearby objects.
