AI Article Synopsis
- Limited data on mental confusion after open heart surgery shows it affects a notable percentage of older patients, particularly those undergoing valvular surgery.
- Preoperative risk factors for confusion in patients aged 75 and older include diabetes, heart failure history, weak carotid pulses, and having repeat surgeries.
- Older patients who experience mental confusion post-surgery face higher late mortality rates and significant declines in quality of life compared to younger patients.
Article Abstract
Background: Limited data exist about the incidence and consequences of mental confusion following open heart surgery in different age groups. Likewise, little is known about preoperative predictors of mental confusion.
Methods: Two-hundred consecutive patients, aged > or =75 years (Group 1), and 400 procedure- and gender-matched younger patients (Group 2) who underwent coronary or valvular surgery were included in a prospective study. The relation between postoperative mental confusion, mortality, morbidity, and quality of life was studied.
Results: Mental confusion was present in 11.8% Group 2 and 22.6% Group 1 patients. The incidence was higher after valvular surgery. Preoperative risk factors in Group 1 patients were diabetes mellitus, a history of heart failure, weak carotid pulsations, and repeat surgery. Late mortality, after a median follow-up duration of 31 months, was significantly worse in patients who were confused, which was related to the underlying disease. Recovery of quality of life was clearly diminished in elderly patients with confusion in contrast to younger patients.
Conclusion: Postoperative mental confusion has a high incidence in the elderly population and is associated with a diminished quality of life.

Classification-based pathway analysis using GPNet with novel P-value computation.
Brief Bioinform

Center for Artificial Intelligence Research, Wake Forest University School of Medicine, Winston-Salem, NC 27101, United States.
Pathway analysis plays a critical role in bioinformatics, enabling researchers to identify biological pathways associated with various conditions by analyzing gene expression data. However, the rise of large, multi-center datasets has highlighted limitations in traditional methods like Over-Representation Analysis (ORA) and Functional Class Scoring (FCS), which struggle with low signal-to-noise ratios (SNR) and large sample sizes. To tackle these challenges, we use a deep learning-based classification method, Gene PointNet, and a novel $P$-value computation approach leveraging the confusion matrix to address pathway analysis tasks.

Adverse Childhood Experiences and Subjective Cognitive Decline Among Transgender Adults.

Nell Hodgson Woodruff School of Nursing, Emory University, Atlanta, Georgia, USA.
Introduction: Adverse childhood experiences (ACEs) are associated with an increased risk of developing chronic health conditions, including Alzheimer's disease and related dementias (ADRD) and subjective cognitive decline (SCD), self-reported confusion/memory loss, and an early clinical manifestation of ADRD. While ACEs and SCD have both been individually studied in transgender and nonbinary (TGN) adults, no study has examined the relationship between the two among this population. This study sought to establish the prevalence of ACEs and their association with SCD among TGN adults.

Progress towards achieving global elimination of hepatitis B virus (HBV) by 2030 remains unsatisfactory. Prevention of mother to child transmission is crucial but current Clinical Practice Guidelines (CPGs) gave diverse recommendations, creating confusion and leading to significant challenges in the practical implementation across various regions owing to global inequity. We reviewed 47 CPGs on the management of hepatitis B during pregnancy against twelve important clinical questions.
