Piezoelectric Materials in Medical Ultrasound: A Comprehensive Review From Fundamentals to Translational Prospects

Information &Functional Materials, EarlyView.
Piezoelectric materials are reviewed as active platforms for medical ultrasound, bridging electromechanical fundamentals, transducer architectures, and biomedical applications. Material–device co‐design is emphasized as the key to high‐performance diagnosis, therapy, monitoring, wearable ultrasound, and emerging ultrasound‐responsive functions ...

Metabolic Syndrome and Dementia Risk in Older Adults: A Narrative Review

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Dementia is a major global health issue in aging societies. Metabolic syndrome (MetS), a cluster of metabolic abnormalities, has been proposed as a modifiable risk factor for dementia, although existing evidence remains inconsistent. This review examined recent studies on the association between MetS and dementia risk in older adults.

Análise da capacidade reactiva da circulação intracerebral pelo efeito do CO2. Um método de fácil execução.

Acta Médica Portuguesa, 1998
Maintenance of cerebral perfusion pressure is a prerequisite for the prevention of cerebral ischaemia. Physiological fluctuations in systemic perfusion pressure are compensated by cerebrovascular autoregulation.

Mechanisms of Cough Syncope as Evaluated by the Valsalva Maneuver

Kaohsiung Journal of Medical Sciences, 2007
Transcranial Doppler is often employed for the assessment of cerebral hemodynamics. The study by Chao et al in the February 2007 issue of the journal raises some important issues regarding the understanding of the mechanisms involved in cough syncope. We

Identification of predictive factors for reversal of cerebral vasculopathy in an original longitudinal cohort study in newborns with sickle cell anaemia

British Journal of Haematology, EarlyView.
Summary Cerebral macrovasculopathy (CV) is a major complication in children with sickle cell anaemia (SCA) and usually requires a long‐term transfusion programme (TP) to prevent stroke. This study aimed to identify factors predicting reversal of CV on TP in a single‐centre newborn cohort. Among 375 patients, 50 presented CV and received TP.

Ischaemic stroke and 5‐fluorouracil or capecitabine: A systematic review and meta‐analysis of harms and a retrospective study of the WHO pharmacovigilance database

British Journal of Pharmacology, EarlyView.
Abstract Aim Fluoropyrimidines, including 5‐fluorouracil (5‐FU) and capecitabine, are cornerstone antineoplastic agents for cancer. Case reports suggest that these drugs may be associated with an under‐recognised risk of ischaemic stroke or transient ischaemic attack (TIA).
