Inhibitory control develops in early childhood, and atypical development may be a measurable marker of risk for the later development of psychosis. Additionally, inhibitory control may be a target for intervention.

Behavioral performance on a developmentally appropriate Go/No-Go task including a frustration manipulation completed by children ages 3–5 years (early childhood; n = 107) was examined in relation to psychotic-like experiences (PLEs; ‘tween’; ages 9–12), internalizing symptoms, and externalizing symptoms self-reported at long-term follow-up (pre-adolescence; ages 8–11). ERP N200 amplitude for a subset of these children (n = 34) with electrophysiological data during the task was examined as an index of inhibitory control.

Children with lower accuracy on No-Go trials compared to Go trials in early childhood (F(1,101) = 3.976, p = 0.049), evidenced higher PLEs at the transition to adolescence 4–9 years later, reflecting a specific deficit in inhibitory control. No association was observed with internalizing or externalizing symptoms. Decreased accuracy during the frustration manipulation predicted higher internalizing, F(2,202) = 5.618, p = 0.004, and externalizing symptoms, F(2,202) = 4.663, p = 0.010. Smaller N200 amplitudes were observed on No-Go trials for those with higher PLEs, F(1,101) = 6.075, p = 0.020; no relationship was observed for internalizing or externalizing symptoms.

Long-term follow-up demonstrates for the first time a specific deficit in inhibitory control behaviorally and electrophysiology, for individuals who later report more PLEs. Decreases in task performance under frustration induction indicated risk for internalizing and externalizing symptoms. These findings suggest that pathophysiological mechanisms for psychosis are relevant and discriminable in early childhood, and further, suggest an identifiable and potentially modifiable target for early intervention.

To assess the prevalence of antibiotic-resistant gram-negative bacteria (R-GNB) among patients without recent hospitalization and to examine the influence of outpatient antibiotic exposure on the risk of acquiring R-GNB in this population.

2-year retrospective cohort study.

Regional Veterans Affairs healthcare system.

Outpatients at 13 community-based clinics.

We examined the rate of acquisition of R-GNB within 90 days following an outpatient visit from 2018 to 2019. We used clinical and administrative databases to determine and summarize prescriptions for systemic antibiotics, associated infectious diagnoses, and subsequent R-GNB acquisition among patients without recent hospitalizations. We also calculated the odds ratio of R-GNB acquisition following antibiotic exposure.

During the 2-year study period, 7,215 patients had outpatient visits with microbiological cultures obtained within 90 days. Of these patients, 206 (2.9%) acquired an R-GNB. Among patients receiving antibiotics at the visit, 4.6% acquired a R-GNB compared to 2.7% among patients who did not receive antibiotics, yielding an unadjusted odds ratio of 1.75 (95% confidence interval, 1.18–2.52) for a R-GNB following an outpatient visit with versus without an antibiotic exposure. Regardless of R-GNB occurrence, >50% of antibiotic prescriptions were issued at visits without an infectious disease diagnosis or issued without documentation of an in-person or telehealth clinical encounter.

Although the rate of R-GNBs was low (2.9%), the 1.75-fold increased odds of acquiring a R-GNB following an outpatient antibiotic highlights the importance of antimicrobial stewardship efforts in outpatient settings. Specific opportunities include reducing antibiotics prescribed without an infectious diagnosis or a clinical visit.

Litigation in the National Health Service continues to rise with a 9.4 per cent increase in clinical negligence claims from the period 2018 and 2019 to the period 2019 and 2020. The cost of these claims now accounts for 1.8 per cent of the National Health Service 2019 to 2020 budget. This study aimed to identify the characteristics of clinical negligence claims in the subspecialty of otology.

This study was a retrospective review of all clinical negligence claims in otology in England held by National Health Service Resolution between April 2013 and April 2018.

There were 171 claims in otology, 24 per cent of all otolaryngology claims, with a potential cost of £24.5 million. Over half of these were associated with hearing loss. Stapedectomy was the highest mean cost per claim operation at £769 438. The most common reasons for litigation were failure or delay in treatment (23 per cent), failure or delay in diagnosis (20 per cent), intra-operative complications (15 per cent) and inadequate consent (13 per cent).

There is a risk of high-cost claims in otology, especially with objective injuries such as hearing loss and facial nerve injury.

Type 2 diabetes results mainly from weight gain in adult life and affects one in twelve people worldwide. In the Diabetes REmission Clinical Trial (DiRECT), the primary care-led Counterweight-Plus weight management program achieved remission of type 2 diabetes (for up to six years) for forty-six percent of patients after one year and thirty-six percent after two years. The objective of this study was to estimate the implementation costs of the program, as well as its two-year within-trial cost effectiveness and lifetime cost effectiveness.

Within-trial cost effectiveness included the Counterweight-Plus costs (including training, practitioner appointments, and low-energy diet), medications, and all routine healthcare contacts, combined with achieved remission rates. Lifetime cost per quality-adjusted life-year (QALY) was estimated according to projected durations of remissions, assuming continued relapse rates as seen in year two of DiRECT and the consequent life expectancy, quality of life and healthcare costs.

The two-year intervention cost was EUR 1,580 per participant, with over eighty percent of the costs incurred in year one. Compared with the control group, medication savings were EUR 259 (95% confidence interval [CI]: 166–352) for anti-diabetes drugs and EUR 29 (95% CI: 12–47) for anti-hypertensive medications. The intervention was modeled with a lifetime horizon to achieve a mean 0.06 (95% CI: 0.04–0.09) gain in QALYs for the DiRECT population and a mean total lifetime cost saving per participant of EUR 1,497 (95% CI: 755–2,331), with the intervention becoming cost-saving within six years.

The intensive weight loss and maintenance program reduced the cost of anti-diabetes drugs through improved metabolic control, achieved diabetes remission in over one-third of participants, and reduced total healthcare contacts and costs over two years. A substantial lifetime healthcare cost saving is anticipated from periods of diabetes remission and delaying complications. Healthcare resources could be shifted cost effectively to establish diabetes remission services, using the existing DiRECT intervention, even if remissions are only maintained for limited durations. However, more research investment is needed to further improve weight-loss maintenance and extend remissions.

To identify the intracochlear electrode position in cochlear implant recipients and determine the correlation to speech perception for two peri-modiolar electrode arrays.

Post-operative cone-beam computed tomography images of 92 adult recipients of the ‘CI512’ electrode and 18 adult recipients of the ‘CI532’ electrode were analysed. Phonemes scores were recorded pre-implantation, and at 3 and 12 months post-implantation.

All CI532 electrodes were wholly within scala tympani. Of the 79 CI512 electrodes intended to be in scala tympani, 58 (73 per cent) were in scala tympani, 14 (17 per cent) were translocated and 7 (9 per cent) were wholly in scala vestibuli. Thirteen CI512 electrodes were deliberately inserted into scala vestibuli. Speech perception scores for post-lingual recipients were higher in the scala tympani group (69.1 per cent) compared with the scala vestibuli (54.2 per cent) and translocation (50 per cent) groups (p < 0.05). Electrode location outside of scala tympani independently resulted in a 10.5 per cent decrease in phoneme scores.

Cone-beam computed tomography was valuable for demonstrating electrode position. The rate of scala tympani insertion was higher in CI532 than in CI512 electrodes. Scala vestibuli insertion and translocation were associated with poorer speech perception outcomes.

To investigate the effectiveness and usability of automated procedural guidance during virtual temporal bone surgery.

Two randomised controlled trials were performed to evaluate the effectiveness, for medical students, of two presentation modalities of automated real-time procedural guidance in virtual reality simulation: full and step-by-step visual presentation of drillable areas. Presentation modality effectiveness was determined through a comparison of participants’ dissection quality, evaluated by a blinded otologist, using a validated assessment scale.

While the provision of automated guidance on procedure improved performance (full presentation, p = 0.03; step-by-step presentation, p < 0.001), usage of the two different presentation modalities was vastly different (full presentation, 3.73 per cent; step-by-step presentation, 60.40 per cent).

Automated procedural guidance in virtual temporal bone surgery is effective in improving trainee performance. Step-by-step presentation of procedural guidance was engaging, and therefore more likely to be used by the participants.

Evaluating the effectiveness of the Army Aboriginal Community Assistance Programs (AACAPs) from a military participant perspective provides the objective of this research. The study will identify areas of concern and provide guidance on current military policy, doctrine and protocol.

Army Aboriginal Community Assistance Programs (AACAPs) represent a co-operative initiative between the Australian Army and Australian Government, that delivers complex support for Disaster Relief and Humanitarian Assistance (HA/DR) to improve the health and well-being of indigenous communities. Since 1997, the Army has conducted a number of AACAPs in remote Indigenous communities within continental Australia. No previous evaluations of these programs exist.

A ‘Quality Improvement’ study underpins this evaluation. Shewhart’s “Plan, Do, Study, Act” Model provides the guiding framework for the study. Allen’s Logic Model exemplifies the most appropriate framework to articulate the program needs and objectives, and to delineate the processes inherent in the program for this evaluation. The Center for Disease Control (CDC) evaluation model for public health programs, provides the evaluation standards to examine the delivery of health care to the deployed force in an austere environment. Part 1 of the study will be a desktop examination of current military policy, doctrine and protocol relating to AACAP. Part 2 will overlay personal experience from military participants in the AACAPs through a semi-structured interview, to enable deployed health personnel the opportunity to comment on their experiences. Analysis will comprise quantitative and qualitative method, specifically descriptive statistics and thematic analysis respectively. Army has approved all required governance, and ethics approval will be sought from Monash University.

This is a proposed study, no results are available.

The benefit of this research will be gaining new knowledge with context of a humanitarian focused military task, through the lens of quality improvement to build capacity and enhance capability.
