Maternal emotional availability and perinatal depressive symptoms as predictors of early childhood executive function.

Background: The interconnected effects of maternal perinatal depression and the early mother-infant relational quality on children's executive function development are crucial yet understudied. This study addresses this gap, focusing on how perinatal depressive symptoms and emotional availability at 6 months predict child executive function performance at age four, with an emphasis on the moderating role of emotional availability.

Method: This study included 282 mother-infant pairs recruited from the Mercy Pregnancy and Emotional Wellbeing Study, utilising repeated Edinburgh Postnatal Depression Scale measurement over the perinatal period, Emotional Availability Scales, and child executive function assessments (Shape School, NEPSY-II, Preschool Age Psychiatric Assessment, Attention Deficit Hyperactivity scale, inattentive subscale).

Cortico-cortical connectivity is influenced by levodopa in tremor-dominant Parkinson's disease.

Resting tremor is the most common presenting motor symptom in Parkinson's disease (PD). The supplementary motor area (SMA) is a main target of the basal-ganglia-thalamo-cortical circuit and has direct, facilitatory connections with the primary motor cortex (M1), which is important for the execution of voluntary movement. Dopamine potentially modulates SMA and M1 activity, and both regions have been implicated in resting tremor.

Enabling successful life engagement in young people with ADHD: new components beyond adult models of recovery.

Purpose: To examine the lived experiences of young people successfully managing life with ADHD and investigate the applicability of adult models of Recovery to these individuals.

Methods: Twenty-seven young people aged 15-31 years participated in qualitative interviews. Participants' success was indicated by employment, school attendance, absence of acute mental health episodes, or absence of chronic alcohol or drug use.

Reduced SMA-M1 connectivity in older than younger adults measured using dual-site TMS.

With advancing age comes a decline in voluntary movement control. Growing evidence suggests that an age-related decline in effective connectivity between the supplementary motor area and primary motor cortex (SMA-M1) might play a role in an age-related decline of bilateral motor control. Dual-site transcranial magnetic stimulation (TMS) can be used to measure SMA-M1 effective connectivity.

Test Re-test Reliability of Dual-site TMS Measures of SMA-M1 Connectivity Differs Across Inter-stimulus Intervals in Younger and Older Adults.

Dual-site transcranial magnetic stimulation (TMS) is a promising tool to measure supplementary motor area and primary motor cortex (SMA-M1) connectivity in younger and older adults, and could be used to understand the pathophysiology of movement disorders. However, test re-test reliability of dual-site TMS measures of SMA-M1 connectivity has not been established. We examined the reliability of SMA-M1 connectivity using dual-site TMS in two sessions in 30 younger and 30 older adults.

The role of governance in Indigenous medical education research.

Context: This article considers the role of governance in Indigenous medical education research through the lens of an Australian Aboriginal research project titled Healing Conversations. The Healing Conversations project is developing and testing a targeted educational framework for improved clinical communication between healthcare practitioners and Australian Aboriginal peoples in regional and urban locations. It is proposed that an effective governance approach can support Indigenous and non-Indigenous stakeholders to work together in decision-making structures to enable outcomes that promote and prioritise Indigenous worldviews and values in medical education research.

Reduced Cerebellar Brain Inhibition Measured Using Dual-Site TMS in Older Than in Younger Adults.

Dual-site transcranial magnetic stimulation (TMS) can be used to measure the cerebellar inhibitory influence on the primary motor cortex, known as cerebellar brain inhibition (CBI), which is thought to be important for motor control. The aim of this study was to determine whether age-related differences in CBI (measured at rest) were associated with an age-related decline in bilateral motor control measured using the Purdue Pegboard task, the Four Square Step Test, and a 10-m walk. In addition, we examined test re-test reliability of CBI measured using dual-site TMS with a figure-of-eight coil in two sessions.

Morphometric in vivo evidence of thalamic atrophy correlated with cognitive and motor dysfunction in Huntington's disease: The IMAGE-HD study.

In Huntington's disease (HD), neurodegeneration causes progressive atrophy to the striatum, cortical areas, and white matter tracts - components of corticostriatal circuitry. Such processes may affect the thalamus, a key circuit node. We investigated whether differences in dorsal thalamic morphology were detectable in HD, and whether thalamic atrophy was associated with neurocognitive, neuropsychiatric and motor dysfunction.

Two-eyed seeing: A useful gaze in Indigenous medical education research.

Context: Medical education has a role in preparing future health care practitioners to have the skills to meaningfully address health disparities while providing effective clinical care considerate of diversity in our societies. This calls for medical education researchers to approach their craft in ways that prioritise and value inputs from a broader range of perspectives and worldviews in an effort to redress the negative impacts of social, political and structural forces on health outcomes.

Methods: Given the entrenched health inequities experienced by Indigenous populations across the globe, this paper details an approach to medical education research put forward by Canadian Mi'kmaw Elders Murdena and Albert Marshall and named 'two-eyed seeing'.

Relationship Between Vitamin D Status From Childhood to Early Adulthood With Body Composition in Young Australian Adults.

Context: Vitamin D plays a role in the differentiation and metabolism of skeletal muscle and, possibly, adipose tissue; however, the relationship between vitamin D status during growth and body composition in early adulthood is unclear.

Objective: We examined associations between vitamin D status in childhood, adolescence, and early adulthood with body composition at age 20 years.

Design Setting Participants: We studied 821 offspring (385 females) of the Western Australian Pregnancy Cohort Study who had ≥3 serum 25-hydroxyvitamin D [25(OH)D] at age 6, 14, 17, and 20 years and body composition assessed at age 20 using dual-energy x-ray absorptiometry.

Healing Conversations: Developing a Practical Framework for Clinical Communication Between Aboriginal Communities and Healthcare Practitioners.

In recognition of the ongoing health disparities experienced by Aboriginal and Torres Strait Islander peoples (hereafter Aboriginal), this scoping review explores the role and impact of the clinical communication process on Aboriginal healthcare provision. A medical education lens is applied, looking at the utility of a tailored clinical communication framework to assist health practitioners work more effectively with Aboriginal peoples and communities. The initial framework, building on existing communication guides, proposes four domains: content, process, relational and environmental.

Surgical Management of Caseous Calcification of the Mitral Annulus.

Caseous calcification of the mitral annulus (CCMA) is a rare variant of mitral annular calcification; it can manifest with conduction abnormalities or systemic embolization. It typically involves the posterior mitral annulus, and surgery is indicated for severe mitral valve dysfunction, for embolic complications or when the diagnosis is not certain. We describe a structured approach to the surgical management of CCMA using bovine pericardium to repair the defect.

Understanding practitioner professionalism in Aboriginal and Torres Strait Islander health: lessons from student and registrar placements at an urban Aboriginal and Torres Strait Islander primary healthcare service.

Aboriginal and Torres Strait Islander peoples continue to be pathologised in medical curriculum, leaving graduates feeling unequipped to effectively work cross-culturally. These factors create barriers to culturally safe health care for Aboriginal and Torres Strait Islander peoples. In this pilot pre-post study, the learning experiences of seven medical students and four medical registrars undertaking clinical placements at an urban Aboriginal and Torres Strait Islander primary healthcare service in 2014 were followed.

Morphometric analysis of thalamic volume in progressive supranuclear palsy: In vivo evidence of regionally specific bilateral thalamic atrophy.

We investigated whether differences were detectable in the volume and shape of the dorsal thalamus on magnetic resonance imaging in patients with progressive supranuclear palsy (PSP). Manual segmentation of the left and right thalami on magnetic resonance imaging scans occurred in 22 patients with clinically diagnosed PSP and 23 healthy controls; thalamic volumes (left, right, total) were calculated. Between group differences were explored by multivariate analysis of co-variance, using age and intracranial volume as covariates.

Clinical audit project in undergraduate medical education curriculum: an assessment validation study.

Objectives: To evaluate the merit of the Clinical Audit Project (CAP) in an assessment program for undergraduate medical education using a systematic assessment validation framework.

Methods: A cross-sectional assessment validation study at one medical school in Western Australia, with retrospective qualitative analysis of the design, development, implementation and outcomes of the CAP, and quantitative analysis of assessment data from four cohorts of medical students (2011- 2014).

Results: The CAP is fit for purpose with clear external and internal alignment to expected medical graduate outcomes.

Modified Valsalva Maneuver for Venous Cannulation in Cardiopulmonary Bypass for Minimal Incision Mitral Valve Surgery.

A 69-year-old man underwent minimal incision mitral valve repair for severe symptomatic mitral regurgitation. The echocardiography showed that he had normal left ventricular function with a moderately to severely dilated left atrium, a mildly dilated right atrium, and a large patent foramen ovale. The multistage venous cannulation was very challenging because we could not negotiate the guide wire from the inferior vena cava via the right atrium into the superior vena cava.

No additive effect of cannabis on cognition in schizophrenia.

Background: We aimed to examine the association between lifetime cannabis use and estimates of both premorbid and current cognitive function in psychotic disorders in an Australian cohort.

Methods: In an Australian multicenter cohort, 1237 participants with an established ICD-10 diagnosis of psychotic disorder were categorised according to history of lifetime cannabis use (non-users, n=354; cannabis users, n=221; cannabis dependency, n=662). Groups were analyzed according to available indices of cognitive ability: the National Adult Reading Test - Revised (NART-R) for ability prior to illness onset; and the Digit Symbol Coding Test (DSCT) for current ability.
