Ethical Use of Cadaveric Images in Anatomical Textbooks, Atlases, and Journals: A Consensus Response From Authors and Editors.

Nowadays, consent to use donor bodies for medical education and research is obtained from the body donors and their families before the donation. Recently, the International Federation of Associations of Anatomists (IFAA) published guidelines that could restrict the appearance of cadaveric images in commercial anatomical resources such as textbooks and other educational products. These guidelines state that the donor must expressly consent to using such images for this purpose.

Refining breast cancer genetic risk and biology through multi-ancestry fine-mapping analyses of 192 risk regions.

Genome-wide association studies have identified approximately 200 genetic risk loci for breast cancer, but the causal variants and target genes are mostly unknown. We sought to fine-map all known breast cancer risk loci using genome-wide association study data from 172,737 female breast cancer cases and 242,009 controls of African, Asian and European ancestry. We identified 332 independent association signals for breast cancer risk, including 131 signals not reported previously, and for 50 of them, we narrowed the credible causal variants down to a single variant.

Bariatric surgery targeting opioid prescribing: a national model for effectively reducing opioid use after bariatric surgery.

Background: Prescription opioids are responsible for a significant proportion of opioid-related deaths in the United States. Approximately 6% of opioid-naïve patients who receive opioid prescriptions after surgery become chronic opioid users. However, chronic opioid use after bariatric surgery may be twice as common.

Nuclear Cardiology Surrogate Biomarkers in Clinical Trials.

Nuclear cardiology offers a diverse range of imaging tools that provide valuable insights into myocardial perfusion, inflammation, metabolism, neuroregulation, thrombosis, and microcalcification. These techniques are crucial not only for diagnosing and managing cardiovascular conditions but also for gaining pathophysiologic insights. Surrogate biomarkers in nuclear cardiology, represented by detectable imaging changes, correlate with disease processes or therapeutic responses and can serve as endpoints in clinical trials when they demonstrate a clear link with these processes.

Randomized Control Trial Evaluating Different Modalities of Real-Time Surgical Feedback.

Introduction:: Surgical training is a constant exchange between trainers and trainees, and intraoperative surgical feedback is an integral part of learning. New technologies in robotic surgery allow for the delivery of visual aid and verbal feedback intraoperatively, but it has not yet been determined if feedback type affects the trainee learning process.

Methods:: 49 novice participants were recruited and randomized into four feedback groups: , , of verbal/visual, and no feedback ().

Renal Tubule-Specific Angiotensinogen Deletion Attenuates SGLT2 Expression and Ameliorates Diabetic Kidney Disease in Murine Models of Type 1 Diabetes.

The role of the intrarenal renin-angiotensin system (iRAS) in diabetic kidney disease (DKD) progression remains unclear. In this study, we generated mice with renal tubule-specific deletion of angiotensinogen (Agt; RT-Agt-/-) in both Akita and streptozotocin (STZ)-induced mouse model of diabetes. Both Akita RT-Agt-/- and STZ-RT-Agt-/- mice exhibited significant attenuation of glomerular hyperfiltration, urinary albumin/creatinine ratio, glomerulomegaly and tubular injury.

The Utility of Preoperative Phenylephrine Testing in Müller Muscle Conjunctival Resection Surgery for Involutional Ptosis.

Purpose: Phenylephrine testing prior to Müller muscle conjunctival resection has traditionally been used to predict postoperative outcomes. The purpose of this study is to determine if preoperative phenylephrine testing impacts postoperative changes in eyelid position.

Methods: In this multicenter cross-sectional cohort study, 270 eyelids of participants with involutional ptosis and levator function >12 mm who underwent Müller muscle conjunctival resection were divided into 2 comparison groups.

Basic Science and Pathogenesis.

Background: The Apolipoprotein E ε4 (APOE-ε4) allele is common in the population, but acts as the strongest genetic risk factor for late-onset Alzheimer's disease (AD). Despite the strength of the association, there is notable heterogeneity in the population including a strong modifying effect of genetic ancestry, with the APOE-ε4 allele showing a stronger association among individuals of European ancestry (EUR) compared to individuals of African ancestry (AFR). Given this heterogeneity, we sought to identify genetic modifiers of APOE-ε4 related to cognitive decline leveraging APOE-ε4 stratified and interaction genome-wide association analyses (GWAS).

Basic Science and Pathogenesis.

Background: An emerging theory suggests a link between Alzheimer's disease (AD) and microbial infection. Notably, various microbes have been detected in the post-mortem brains of AD patients and murine models. However, there exists a gap in research concerning the presence and role of microbial infection in the AD retina, which shares common pathogenesis with the brain.

Basic Science and Pathogenesis.

Background: "SuperAgers" are older adults (ages 80+) whose cognitive performance resembles that of adults in their 50s to mid-60s. Factors underlying their exemplary aging are underexplored in large, racially diverse cohorts. Using eight cohorts, we investigated the frequency of APOE genotypes in SuperAgers compared to middle-aged and older adults.

Basic Science and Pathogenesis.

Background: Synaptic loss predicts cognitive decline in Alzheimer's disease (AD). However, the critical disease modifying molecular mechanisms of synaptic failure remain elusive. Animal studies implicate the increased activation of cytosolic phospholipase (cPLA2) activation in synaptic loss and neuroinflammation.

Basic Science and Pathogenesis.

Background: Cerebrovascular disease (CVD) is a major cause of mortality in females, while two-thirds of Alzheimer's disease (AD) patients are female. AD and CVD share many genetic risk factors, one of them being apolipoprotein E (APOE) genotype. Sex differences in APOE and AD are well-established; it is unclear if associations between APOE and CVD are sex-specific.

Basic Science and Pathogenesis.

Background: Alzheimer's disease (AD) is a progressive irreversible dementia characterized by beta-amyloid protein plaque deposition and hyperphosphorylation of tau forming neurofibrillary tangles, and neurodegeneration. An emerging theory posits that infections could be one of the triggering factors in AD development and progression. Multiple lines of evidence have linked Chlamydia pneumoniae (Cp), a gram-negative obligate intracellular bacterium with AD.

Basic Science and Pathogenesis.

Background: Mitochondrial dysfunction is an early and prominent feature of Alzheimer's disease (AD). We have recently published that lower brain mitochondrial DNA copy number (mtDNAcn) is associated with increased risk of AD neuropathological change and reduced cognitive performance. Here, we addressed how mtDNAcn affects cell-type specific phenotypes.

Basic Science and Pathogenesis.

Background: Alzheimer's disease (AD) is the foremost cause of global dementia, also characterized by retinal changes involving Aβ, hyperphosphorylated-tau (p-tau), neuronal degeneration, and tissue atrophy. Mitochondrial-driven reactive oxygen species (ROS) production, linked to synaptic dysfunction, is common to various neurodegenerative conditions, including AD. Despite synaptic dysfunction being an early predictor of cognitive decline in AD, its occurrence in the AD retina is unexplored.

Basic Science and Pathogenesis.

Background: Alzheimer's Disease (AD) and Age-Related Macular Degeneration (AMD) are two age related neurodegenerative diseases that share multiple characteristics, including deposition of amyloid beta. In AD, amyloid plaque accumulation contributes to neurological dysfunction, while in AMD amyloid is a component of the hallmark retinal drusen complexes that lead to degeneration of central vision. Both diseases have significant and opposite risk due to the APOE e4 and e2 alleles.

Basic Science and Pathogenesis.

Background: This study identifies and quantifies diverse pathological tau forms in the retina at both early and advanced stages of Alzheimer's disease (AD) and assesses their correlation with disease status. In the pathogenesis of AD, the tau protein undergoes post-translational modifications, including hyperphosphorylation (p-tau). As the disease progresses, pathological tau can propagate as oligomers, aggregate into fibrils, and paired helical filaments (PHF), and ultimately form intraneuronal neurofibrillary tangles (NFTs).

Basic Science and Pathogenesis.

Background: Cerebrovascular pathology frequently co-occurs with Alzheimer's disease (AD) pathology and the combinations of these forms of pathology may underly AD dementia. Sex hormones influence many aspects of cerebrovascular systems and may contribute to cerebrovascular pathology, but many studies of aging and AD do not measure hormones. Therefore, in this study, we explored whether a polygenic score predicting sex hormone levels relates to cerebrovascular pathology in the AD brain.
