Background: Genetic variants may confer risk for depression by modulating brain structure and function; evidence has underscored the key role of the subgenual anterior cingulate cortex (sgACC) in depression. We sought to examine how the resting-state functional connectivity (rsFC) of the sgACC was associated with polygenic risk for depression in a subclinical population.

Methods: Following published protocols, we computed seed-based whole-brain sgACC rsFC and calculated polygenic risk scores (PRS) using data from healthy young adults from the Human Connectome Project.

Conditional Generative Models for Synthetic Tabular Data: Applications for Precision Medicine and Diverse Representations.

Annu Rev Biomed Data Sci

January 2025

2Departments of Bioengineering and Genetics, Stanford University, Stanford, California, USA.

Tabular medical datasets, like electronic health records (EHRs), biobanks, and structured clinical trial data, are rich sources of information with the potential to advance precision medicine and optimize patient care. However, real-world medical datasets have limited patient diversity and cannot simulate hypothetical outcomes, both of which are necessary for equitable and effective medical research. Fueled by recent advancements in machine learning, generative models offer a promising solution to these data limitations by generating enhanced synthetic data.

Selenium deficiency associated with a high risk of many diseases remains a global challenge. Owing to the narrow margin between "nutrition-toxicity" doses of selenium, it is imperative to achieve accurate selenium supplement. Nano‑selenium (SeNPs) is a novel form of selenium supplement with low toxicity, but it could be trapped and removed by intestinal mucus, thus limiting its oral delivery.

Enhancing the passivation of heavy metals and increasing organic matter content during the composting of sewage sludge poses significant challenges for maximizing its utilization value. Results indicated that in the control, biochar, microbial agents and microbial agents-loaded biochar (BCLMA) groups, BCLMA addition led to a higher composting temperature, with increases of 17-62% in humic acid, 25-73% in germination index, and 30-35% in organic matter consumption. And the residual fraction of Cu, Zn, Cr and Cd were increased by 30%, 12%, 22%, and 17%, respectively.

Protein-based nanomachines drive every cellular process. An explosion of high-resolution structures of multiprotein complexes has improved our understanding of what these machines look like and how they work, but we still know relatively little about how they assemble in living cells. For example, it has only recently been appreciated that many complexes assemble co-translationally, with at least one subunit still undergoing active translation while already interacting with other subunits.

Mg-dependent mechanism of environmental versatility in a multidrug efflux pump.

Tripartite resistance nodulation and cell division multidrug efflux pumps span the periplasm and are major drivers of multidrug resistance among gram-negative bacteria. Cations, such as Mg, become concentrated within the periplasm and, in contrast to the cytoplasm, its pH is sensitive to conditions outside the cell. Here, we reveal an interplay between Mg and pH in modulating the structural dynamics of the periplasmic adapter protein, AcrA, and its function within the prototypical AcrAB-TolC multidrug pump from Escherichia coli.

Clinical short-read exome and genome sequencing approaches have positively impacted diagnostic testing for rare diseases. Yet, technical limitations associated with short reads challenge their use for the detection of disease-associated variation in complex regions of the genome. Long-read sequencing (LRS) technologies may overcome these challenges, potentially qualifying as a first-tier test for all rare diseases.

Is it possible for a low-volume surgeon to enhance their surgical skills without performing actual surgeries by utilizing virtual reality headsets and emerging technologies? It has been observed that the time spent by surgical assistants in the operating room decreased after the post-shift leave regulation. In the literature, the use of virtual reality simulations as a support tool in surgical training is recommended. Although the efficacy of virtual reality surgical simulations in surgeries such as arthroscopy and laparoscopy has been proven, there are limited studies on their effect in open surgeries.

When acute myocardial infarction meets renal abscess: Case report and literature review.

Medicine (Baltimore)

November 2024

Institute of Gerontology, Guangzhou Geriatric Hospital, Guangzhou Medical University, Guangzhou, China.

Rationale: Acute myocardial infarction (AMI) is the leading global cause of death from cardiovascular disease, and the mortality rate increases in the presence of comorbidities such as renal abscess. The treatment of AMI combined with renal abscess is challenging, especially in combination with urinary tract obstruction, as percutaneous coronary intervention (PCI) can lead to progression of the renal abscess and deterioration of renal function. Currently, there is no consensus on the treatment of renal abscess in AMI.

Department of Internal Medicine, Kangnam Sacred Heart Hospital, Hallym University College of Medicine, Seoul, Republic of Korea.

Background: Chronic kidney disease (CKD) patients face critical decisions in choosing kidney replacement therapy such as hemodialysis (HD) or peritoneal dialysis (PD), which significantly affect their quality of life and health outcomes. Recent studies highlight the importance of shared decision-making (SDM) in helping patients understand their treatment options and make informed choices. SDM not only improves patient satisfaction and autonomy but also emphasizes the need for comprehensive pre-dialysis education to support optimal treatment selection.
