Purpose: Speech-language pathologists (SLPs) work in Australian schools yet, little is documented about their service delivery practices. This study therefore explores Australian speech-language pathology service delivery in schools, inclusive of work activities, caseloads, and assessment and intervention practices.
Method: An online survey comprising multiple choice, constant sum, Likert scale, and open text questions was completed by 105 SLPs.
Primary cilia are antenna-like organelles which sense extracellular cues and act as signalling hubs. Cilia dysfunction causes a heterogeneous group of disorders known as ciliopathy syndromes affecting most organs. Cilia disassembly, the process by which cells lose their cilium, is poorly understood but frequently observed in disease and upon cell transformation.

Methods: From October 2016 to July 2022, patients undergoing initial full-thickness macular hole repair with the ILM flap or ILM peel technique were reviewed. Final outcomes were recorded and based on size in microns: 401 to 800, 801 to 1,200, and >1,200.
Smooth muscle cells transition reversibly between contractile and noncontractile phenotypes in response to diverse influences, including many from mitochondria. Numerous molecules including myocardin, procontractile miRNAs, and the mitochondrial protein prohibitin-2 promote contractile differentiation; this is opposed by mitochondrial reactive oxygen species (mtROS), high lactate concentrations, and metabolic reprogramming induced by mitophagy and/or mitochondrial fission. A major pathway through which vascular pathologies such as oncogenic transformation, pulmonary hypertension, and atherosclerosis cause loss of vascular contractility is by enhancing mitophagy and mitochondrial fission with secondary effects on smooth muscle phenotype.

A single communication tool across multiple pre-hospital and hospital settings, and between hospital departments is a novel solution to current systems. Fit-for-purpose, secure smartphone applications allow clinical information to be shared quickly between health providers.

Medical records within a multicenter retina practice in Houston, Texas, from January 2015 to August 2021 were retrospectively reviewed. The primary outcome was rate of endophthalmitis after intravitreal injection.

Limited studies have investigated Aboriginal English (home language) dialect in First Nations children and its impact on differential diagnosis of language disorder. This study measured the density of home language dialect and grammatical accuracy in oral narratives produced by typically developing First Nations children.

This study explores whether this disparity affects the clinical trial enrollment process in the retina field and aims to inform future trial recruitment and enrollment. Age, gender, race, ethnicity, preferred language, insurance status, social security number (SSN) status, and median household income (estimated using street address and zip code) for patients referred to at least one prospective, retina-focused clinical trial at a large, urban, retina-based practice were retrospectively extracted using electronic medical records.

Background: This study investigated factors associated with fellow eye horseshoe retinal tear (HST) development in consecutive patients with a presenting eye HST.
Materials And Methods: Medical records were reviewed for patients with initial HSTs between 2015 and 2017 and 24 factors were analyzed. Logistic regression was used to assess factors associated with fellow eye HST development.
Purpose: To evaluate the association of posterior vitreous opacities (PVOs) on optical coherence tomography with retinal tears identified on examination in patients with acute, symptomatic posterior vitreous detachment (PVD).
Methods: Data were retrospectively collected from the medical records of 388 patients with acute, symptomatic PVD between January 1, 2021, and June 30, 2021. Included patients had received a primary diagnosis of PVD and presented with flashes and/or floaters.
PTEN is one of the most commonly inactivated tumour suppressor genes in sporadic cancer. Germline heterozygous PTEN gene alterations also underlie PTEN hamartoma tumour syndrome (PHTS), a rare human cancer-predisposition condition. A key feature of systemic PTEN deregulation is the inability to adequately dampen PI3-kinase (PI3K)/mTORC1 signalling.

Design: Real-world feasibility study, quasi-experimental design.
Setting: Prehospital (25 Ambulance Victoria branches) and within-hospital (2 hospitals) in regional Victoria, Australia.
Objective: To investigate the occurrence of and risk factors for progression of carotid intima media thickness (IMT) and plaque in women with and without SLE.
Methods: A cohort of 149 women with SLE and 126 controls participated in SOLVABLE (Study of Lupus Vascular and Bone Long-term Endpoints). Demographics, cardiovascular and SLE factors, and laboratory assessments were collected at baseline.
Purpose: To describe the visual acuity and anatomic outcomes of intravitreal methotrexate (MTX) for the treatment of primary vitreoretinal lymphoma (PVRL).
Methods: Single-center retrospective case series of patients with a diagnosis of PVRL treated with intravitreal MTX. Patient records were reviewed for demographic information, ocular exam findings, and treatment regimens including number of MTX injections.

The rate-limiting enzyme for vascular contraction, myosin light chain kinase (MLCK), phosphorylates regulatory myosin light chain (MLC) at rates that appear faster despite lower MLCK abundance in fetal compared with adult arteries. This study explores the hypothesis that greater apparent tissue activity of MLCK in fetal arteries is due to age-dependent differences in intracellular distribution of MLCK in relation to MLC. Under optimal conditions, common carotid artery homogenates from nonpregnant adult female sheep and near-term fetuses exhibited similar values of and for MLCK.

: The suitability of existing speech-language pathology assessments for Australian Aboriginal and Torres Strait Islander (Indigenous) children is questioned in the literature. There is emerging evidence that the differences reported between Indigenous and non-Indigenous Australian children on standardised assessment are diminished on more naturalistic assessments such as narrative production (macrostructure and microstructure). Little is documented, however, about the narrative comprehension skills of Australian children.

From day 10 of gestation until term, MUN and MUN-metyrapone (MUN-MET) group rats consumed a diet restricted to 50% of calories consumed by a pair-fed control; and on gestational day 11 through term, MUN-MET groups received drinking water containing MET (0.5 mg/mL), a corticosteroid synthesis inhibitor.

Changes in vascular contractility are among the most important physiological effects of acute and chronic fetal hypoxia. Given the essential role of myosin light-chain kinase (MLCK) in smooth muscle contractility and its heterogeneous distribution, this study explores the hypothesis that subcellular changes in MLCK distribution contribute to hypoxic modulation of fetal carotid artery contractility. Relative to common carotid arteries from normoxic term fetal lambs (FN), carotids from fetal lambs gestated at high altitude (3,802 m) (FH) exhibited depressed contractility without changes in MLCK mRNA or protein abundance.

Method: An online survey was used. Descriptive statistics were analysed with SPSS.
A 46-year-old patient with previously documented Ebola virus persistence in his ocular fluid, associated with severe panuveitis, developed a visually significant cataract. A multidisciplinary approach was taken to prevent and control infection. Ebola virus persistence was assessed before and during the operation to provide safe, vision-restorative phacoemulsification surgery.

His recent history of Aspergillus and Nocardia pneumonia with positive bronchoalveolar lavage, in concert with vitritis and subretinal abscess, were concerning for endogenous endophthalmitis. A sputum culture and transbronchial lung biopsy stains grew Nocardia farcinica although aqueous humor sampling was negative.

Observations: A 65-year old female with a history of metastatic breast carcinoma presented to our clinic with a one-month history of blurred vision and floaters of the left eye. Fundoscopy of the left eye revealed a flesh colored nodule with white lobules demonstrating an endophytic growth pattern from the optic nerve.
Intracerebral hemorrhage (ICH) remains one of the most debilitating types of stroke and is characterized by a sudden bleeding from a ruptured blood vessel. ICH often results in high mortality and in survivors, permanent disability. Most studies have focused on neuroprotective strategies designed to minimize secondary consequences and prevent further pathology.
