Consensus statement for the management of incidentally found brain white matter hyperintensities in general medical practice
Med J Aust. 2023 Aug 21. doi: 10.5694/mja2.52079. Online ahead of print.ABSTRACTINTRODUCTION: There is a paradigm shift in our understanding of white matter hyperintensities (WMH) found on brain imaging. They were once thought to be a normal phenomenon of ageing and, therefore, warranted no further investigation. However, evidence now suggests these lesions are markers of poor brain and cardiovascular health, portending an increased risk of stroke, cognitive decline, depression and death. Nevertheless, no specific guidelines exist for the management of incidentally found WMH for general medical practitioners and other clin...

Rural versus metropolitan comparison of processes of care in the community-based management of TIA and minor stroke in Australia (an analysis from the INSIST study)
CONCLUSIONS: Although TIAMS prognosis in rural settings where solely GP care is common is very good, the processes of care in such areas are inferior to metropolitan. This suggests there is further scope to support rural GPs to optimise care of TIAMS patients.PMID:36382851 | DOI:10.1111/ajr.12950

Acute Fluctuant Neurological Symptoms in Stable Chronic Cryptococcus gattii Cryptococcomas: A Novel Disease Complication
Conclusions: Central nervous system cryptococcomas are difficult to treat, chronic infections, that in our patient had lasted over 10 years despite treatment compliance. A true cryptococcal meningitis relapse is indicated by positive cell cultures in previously sterile fluid but cryptococcoma progression is measured by serial magnetic resonance imaging or computed tomography scans. In the case of progression or relapse induction and consolidation therapy should be restarted. Our patient demonstrated neither relapse nor progression but presented with a novel disease complication of acute fluctuating neurology in chronic...

Correlation Between Intracranial Arterial Calcification and Imaging of Cerebral Small Vessel Disease
Conclusion: Intracranial artery calcification is common in patients with ischemic cerebrovascular disease and the intracranial carotid artery is most frequently affected. Intracranial arterial calcifications might be associated with imaging markers of SVD and are highly correlated with WMHs, lacunes, and CMBs. Quantification of calcification on CT provides additional information on the pathophysiology of SVD. Intracranial arterial calcification could act as a potential marker of SVD. Introduction Atherosclerosis is a systemic vascular process that is considered a major cause of cerebrovascular and cardiovascular di...

Acupuncture for Post-stroke Shoulder-Hand Syndrome: A Systematic Review and Meta-Analysis
Conclusions: Acupuncture therapy seems effective for motor function, pain relief and activities of daily living in stroke patients with mild SHS, when it is used in combination with rehabilitation. The low certainty of evidence downgrades our confidence in making recommendations to clinical practice. Introduction Shoulder-hand syndrome (SHS) is a common condition among people who have had a stroke, with its reported prevalence ranging from 12% to 49% (1, 2). The main symptoms of SHS include pain, hyperalgesia, joint swelling and limitations in range of motion (ROM) (3). Post-stroke SHS is also named type I complex ...

Neuromuscular and Muscle Metabolic Functions in MELAS Before and After Resistance Training: A Case Study
Conclusion To conclude, this study suggests a preserved plasticity in the skeletal muscle of a patient with MELAS. More importantly, Resistance Training appears to be a safe and effective method to increase skeletal muscle function in this patient population, and this effect is mediated by both neuromuscular and mitochondrial adaptations. However, particular attention and caution is needed in the interpretation of the data of this single case study and further studies are warranted including larger sample of patients. Ethics Statement For this case study the participant caregiver provided written informed consent. Auth...

Beta Amyloid Deposition Is Not Associated With Cognitive Impairment in Parkinson's Disease
In this study, we used a well-validated visual assessment to clinically rate scans as being amyloid positive or negative (38). As there is not an accepted threshold based on standardized centiloid reference regions, we defined an amyloid positivity centiloid cut-off threshold in our sample. Our cut-off (CL = 31.3, SUVR = 1.21) corresponds well to the estimated value proposed by Rowe and colleagues (34) in the context of AD (CL = 25–30), however our estimated threshold may be biased by the low number of Aβ positive patients. Our results suggest a lower prevalence of amyloid-positive PDD individuals than in ...

The Predictive Capacity of the Buffalo Concussion Treadmill Test After Sport-Related Concussion in Adolescents
Conclusion This study found that the ΔHR (HRt minus resting HR) correlated with duration of clinical recovery in participants who were prescribed relative rest or a placebo-stretching program but not for participants prescribed sub-threshold aerobic exercise. A ΔHR of ≤50 bpm on the BCTT was 73% sensitive and 78% specific for predicting delayed recovery in concussed adolescents prescribed the current standard of care (i.e., cognitive and physical rest). This has implications for planning team and school activities in adolescents who sustain SRC. Ethics Statement This study was carried out in acco...

Neurophysiological Analysis of Intermanual Transfer in Motor Learning
In this study, MEPs were induced during the subject’s imaged kinesthetic MI. This involves recalling muscle contraction based on a muscle sensory image and was reported to indicate the activity of brain regions similar to those involved in actual muscle contraction (Ruby and Decety, 2001). In the transfer training group, the muscle sensory image evaluation correlated to the actual task execution with the right hand. As a result, it was easy to recall the kinesthetic MI for the training task, thus affecting MI of the non-trained limbs so that MEP changes occurred in the left hand’s MI. In addition, brain exc...

Frequency of Hemorrhage on Follow Up Imaging in Stroke Patients Treated With rt-PA Depending on Clinical Course
Conclusions: Frequency of hemorrhagic transformation in Routine follow-up brain imaging and consecutive changes in therapeutic management were different depending on clinical course measured by NHISS score. Introduction Brain imaging 24–36 h after systemic thrombolysis for acute ischemic stroke is recommended in American Stroke Association and European Stroke Organization guidelines (1, 2). Brain imaging is performed to detect secondary bleeding or hemorrhagic transformation in order to adapt medical stroke prevention if necessary. Guideline recommendations are based on the results of the first study on rt-PA...

Motor Abilities in Adolescents Born Preterm Are Associated With Microstructure of the Corpus Callosum
Conclusions: Impairments in motor abilities are present in preterm born adolescents without major neuromotor impairment and in the absence of focal brain injury. Altered microstructure of the corpus callosum microstructure appears a crucial factor, in particular for movement quality. Introduction Very preterm birth (birth <32 weeks of gestation) is associated with high risk of impaired neurodevelopment. Rates of severe neuromotor impairment, i.e., Cerebral Palsy (CP), are decreasing, in particular in those preterm children born with moderately low and very low birth weight (1). However, in a substantial propo...
