Unlabelled: This study aimed to evaluate the results of magnetic resonance imaging (MRI) surveillance of implant-based breast reconstruction in patients with breast cancer.

Methods: This retrospective observational study analyzed patients who underwent implant-based breast reconstruction and MRI surveillance by a single surgeon from March 2011 to December 2018, in a single center. All patients were informed about the recommendation of the Food and Drug Administration for MRI surveillance, and they choose to undergo MRI 3 years after surgery.

Results: The compliance rate for MRI surveillance was 56.5% (169/299). MRI surveillance was performed at a mean of 45.8 (4.04 years) ± 11.5 months after surgery. One patient (0.6%) showed an abnormal finding of an intracapsular rupture of the silicone implant.

Conclusions: MRI surveillance for implant rupture in implant-based breast reconstruction showed a low incidence of silent implant rupture (0.6%), whereas the compliance of MRI was relatively high (56.5%). These results raise questions about whether taking an MRI in 3-4 years is suitable for imaging surveillance of breast silicone implants. Screening recommendations should be more evidence-based, and more studies are needed to prevent unnecessary screening and patient burden.

Identifying cell types and brain regions critical for psychiatric disorders and brain traits is essential for targeted neurobiological research. By integrating genomic insights from genome-wide association studies with a comprehensive single-cell transcriptomic atlas of the adult human brain, we prioritized specific neuronal clusters significantly enriched for the SNP-heritabilities for schizophrenia, bipolar disorder, and major depressive disorder along with intelligence, education, and neuroticism. Extrapolation of cell-type results to brain regions reveals the whole-brain impact of schizophrenia genetic risk, with subregions in the hippocampus and amygdala exhibiting the most significant enrichment of SNP-heritability.

Background: This study aimed to evaluate the incidence, contributing factors, and clinical outcomes of acquired cystic kidney disease (ACKD) in children undergoing kidney replacement therapy (KRT).

Methods: We conducted a cross-sectional, territory-wide study at the designated pediatric nephrology center in Hong Kong. ACKD was defined as the presence of ≥ 3 cysts in the native kidneys, excluding congenital or hereditary cystic diseases.

A male in his 20s presented with episodic headache and subsequently developed episodic unilateral weakness, dysphasia and encephalopathy. These paroxysmal episodes persisted over time with the development of background cognitive impairment and neuropsychiatric symptoms. MRI surveillance demonstrated progressive T2 hyperintensity with focal cortical oedema correlating to symptoms observed during clinical episodes.

Glioma is characterized by high heterogeneity and poor prognosis. Attempts have been made to understand its diversity in both genetic expressions and radiomic characteristics, while few integrated the two omics in predicting survival of glioma. This study was intended to investigate the connection between glioma imaging and genome, and examine its predictive value in glioma mortality risk and tumor immune microenvironment (TIME).

Background: MicroRNAs have been linked to dementia. However, understanding their relation to cognition in the general population is required to determine their potential use for the detection and prevention of age-associated cognitive decline and preclinical dementia. Therefore, we examined the association of circulating microRNAs with cognitive performance in a population-based cohort and the possible underlying mechanisms.
