The vision for AI is that a computer model can process information and provide output that is indistinguishable from that of a human and, in specific repetitive tasks, outperform a human's capability. The 2 critical underlying technologies in AI are used for supervised and unsupervised machine learning. Machine learning uses neural networks and deep learning modeled after the human brain from structured or unstructured data sets to learn, make decisions, and continuously improve the model. Natural language processing, used for supervised learning, is understanding, interpreting, and generating information using human language in chatbots and generative and conversational AI. These breakthroughs result from increased computing power and access to large data sets, setting the stage for releasing large language models, such as ChatGPT and others, and new imaging models using computer vision. Hypertension management involves using blood pressure and other biometric data from connected devices and generative AI to communicate with patients and health care professionals.

Podocytes exhibit a unique arborized morphology with foot processes interfacing by slit diaphragms, ladder-like, multimolecular sieves, which provide size and charge selectivity for ultrafiltration and transmembrane signaling. Podocyte dysfunction, resulting from oxidative stress, dysregulated prosurvival signaling, or structural damage, can drive the development of proteinuria and glomerulosclerosis in hypertensive nephropathy. Functionally, podocyte injury leads to actin cytoskeleton rearrangements, foot process effacement, dysregulated slit diaphragm protein expression, and impaired ultrafiltration. Notably, the renin-angiotensin system plays a pivotal role in podocyte function, with beneficial AT2R (angiotensin receptor 2)-mediated nitric oxide (NO) signaling to counteract AT1R (angiotensin receptor 1)-driven calcium (Ca²⁺) influx and oxidative stress. Disruption of this balance contributes significantly to podocyte dysfunction and drives albuminuria, a marker of kidney damage and overall disease progression. Oxidative stress can also lead to sustained ion channel-mediated Ca²⁺ influx and precipitate cytoskeletal disorganization. The complex interplay between GPCR (G-protein coupled receptor) signaling, ion channel activation, and redox injury pathways underscores the need for additional research aimed at identifying targeted therapies to protect podocytes and preserve glomerular function. Earlier detection of albuminuria and podocyte injury through routine noninvasive diagnostics will also be critical in populations at the highest risk for the development of hypertensive kidney disease. In this review, we highlight the established mechanisms of oxidative stress-mediated podocyte damage in proteinuric kidney diseases, with an emphasis on a hypertensive renal injury. We will also consider emerging therapies that have the potential to selectively protect podocytes from redox-related injury.</p>","PeriodicalId":13042,"journal":{"name":"Hypertension","volume":" ","pages":"14-25"},"PeriodicalIF":6.9,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11655258/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142619264","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The artificial intelligence (AI) field is advancing quickly, and there has been little discussion on how AI could be leveraged for improving the diagnosis and management of hypertension. AI technologies, including machine learning tools, could alter the way we diagnose and manage hypertension, with potential impacts for improving individual and population health. The development of successful AI tools in public health and health care systems requires diverse types of expertise with collaborative relationships between clinicians, engineers, and data scientists. Unbiased data sources, management, and analyses remain a foundational challenge. From a diagnostic standpoint, machine learning tools may improve the measurement of blood pressure and be useful in the prediction of incident hypertension. To advance the management of hypertension, machine learning tools may be useful to find personalized treatments for patients using analytics to predict response to antihypertension medications and the risk for hypertension-related complications. However, there are real-world implementation challenges to using AI tools in hypertension. Herein, we summarize key findings from a diverse group of stakeholders who participated in a workshop held by the National Heart, Lung, and Blood Institute in March 2023.

We hypothesized that less severe autonomic impairment was associated with greater pressor responses to pyridostigmine.METHODSTo identify predictors of pressor response, linear regression analyses between the effect of pyridostigmine on upright BP and markers of autonomic impairment were retrospectively conducted on 38 patients who had a medication trial with pyridostigmine (60 mg single dose).RESULTSPyridostigmine increased upright BP by 4±2/3±2 mm Hg but with a wide range of responses (-20/-15 to 29/27 mm Hg; interquartile range, -6/-4 to 11/8 mm Hg). No differences were found between multiple system atrophy (n=14) and patients with pure autonomic failure (n=24). The upright BP response to pyridostigmine was negatively correlated with supine BP and with the pressure recovery time of the Valsalva maneuver, an index of severity of autonomic impairment. In patients with multiple system atrophy, the systolic blood pressure pressor response to pyridostigmine was also positively correlated with the increase in upright heart rate divided by the fall in systolic blood pressure (∆ heart rate/∆ systolic blood pressure) and with upright plasma norepinephrine, both surrogates of residual autonomic function.CONCLUSIONSPatients with less severe autonomic impairment are more likely to have a positive pressor response to pyridostigmine. Importantly, in this cohort of patients with severe autonomic failure, pyridostigmine was not effective in those with supine hypertension who would benefit the most from the preferential pressor effect of the drug on upright BP.REGISTRATIONURL: http://www.clinicaltrials.gov; Unique identifier: NCT00223691.","PeriodicalId":13042,"journal":{"name":"Hypertension","volume":"14 1","pages":""},"PeriodicalIF":8.3,"publicationDate":"2024-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142887585","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We sought to determine the relationship between the maternal and fetal genome and maternal levels of sFLT1 at 12, 20, 28, and 36 weeks of gestational age (wkGA).METHODSWe studied a prospective cohort of nulliparous women (3968 mother-child pairs). We related maternal and fetal genotype to the adjusted sFLT1 Z score and sFLT1:placental growth factor (PlGF) ratio Z score at each wkGA and the change in the Z score between 28 and 36 wkGA (Δ36-28). We studied genetic variants from a previous fetal genome-wide association study of preeclampsia and an externally defined polygenic score from a maternal genome-wide association study of preeclampsia.RESULTSFour variants from the fetal preeclampsia genome-wide association study were positively associated with sFLT1 and sFLT1:PlGF Z score at 36 wkGA, and FLT1 enhancer single-nucleotide polymorphisms were associated with increased Δ36-28 of sFLT1. The associations were specific for the fetal genome or stronger for the fetal than the maternal genome. An increased risk of preeclampsia based on the maternal polygenic score for preeclampsia was associated with lower levels of sFLT1 and sFLT1:PlGF ratio in the first trimester and a greater Δ36-28 for sFLT1.CONCLUSIONSThe current data are consistent with a causal association between sFLT1 released by the placenta in late pregnancy and the pathophysiology of preeclampsia.
