Pre-eclampsia is consistently associated with elevated cardiovascular risk extending well beyond pregnancy. Compared with women whose pregnancies are normotensive or uncomplicated, affected women have higher risks of chronic hypertension, coronary heart disease, myocardial infarction, heart failure, stroke and other cerebrovascular disease, arterial disease, cardiovascular hospitalization, and cardiovascular mortality. Across studies, later cardiovascular disease risk is generally approximately two- to fourfold higher, although estimates vary by population, outcome, and follow-up duration. Risk is particularly pronounced after early-onset, severe, preterm, or recurrent disease and when fetal growth restriction is present. The association is partly mediated by subsequent hypertension and cardiometabolic risk factors, while persistent vascular, cardiac, inflammatory, metabolic, and angiogenic abnormalities may also contribute. A history of pre-eclampsia therefore warrants lifelong cardiovascular risk assessment and prevention.
Question: what is the long term cardiovascular risk after pre-eclampsia?
Read the full reviewDie Hypothesen eines veränderten zerebralen Energiestoffwechsels und einer gestörten Perfusionsregulation lassen sich bei ME/CFS bislang nur teilweise empirisch trennen. Hinweise auf Energiestress ergeben sich insbesondere aus erhöhten kortikalen Laktatwerten, während Perfusions- und Hämodynamikstudien regionale, aufgabenabhängige und orthostatisch ausgelöste Auffälligkeiten beschreiben. Einfache Modelle einer dauerhaft bestehenden globalen Hypoperfusion oder eines isolierten primären Energiestoffwechseldefekts werden durch die verfügbaren Befunde jedoch nicht hinreichend gestützt. Vielmehr sprechen die Daten für eine gekoppelte Störung von neuronaler Aktivität, Energieversorgung, Sauerstoffnutzung, Durchblutung und Erholung. Besonders relevant scheint eine unzureichende dynamische Anpassung der zerebralen Durchblutung an kognitive und orthostatische Belastungen zu sein. Zur Klärung der Kausalbeziehungen sind zeitgleiche Messungen von Perfusion, neuronaler Aktivität, Sauerstoffmetabolismus und metabolischen Reserven erforderlich.
Question: Brain-Fog bei ME/CFS: Mich würde interessieren, wie gut sich die Hypothese von verändertem Energiestoffwechsel vs. Perfusionsstörungen empirisch trennen lässt.
Read the full reviewDrug-coated balloon (DCB) treatment is a potential alternative to stenting in selected coronary lesions, but its comparative role across acute coronary syndrome (ACS) and stable coronary artery disease (CAD) remains uncertain. Available evidence includes small randomized ACS trials, randomized studies in stable small-vessel disease, randomized evidence in de novo non-complex CAD, and observational analyses of acute myocardial infarction. Collectively, these studies suggest that DCB can be feasible when lesion preparation produces limited residual stenosis, no major flow-limiting dissection, and acceptable coronary flow. However, DCB has not established broad equivalence or superiority to contemporary drug-eluting stents (DES), particularly in unselected de novo disease. The evidence is limited by small samples, few clinical events, treatment-selection bias, bailout-stenting requirements, and substantial heterogeneity in clinical presentation, lesion type, procedural strategy, and follow-up. A focused systematic review and meta-analysis remains justified, provided that ACS and stable CAD, STEMI and NSTEMI, de novo lesions and in-stent restenosis, and randomized and observational evidence are analyzed separately.
Question: dcb vs stent in acs/cad. Is it worth conducting a meta analysis?
Read the full reviewDie vorliegenden Befunde sprechen nicht für eine eindeutig belegte, dauerhaft bestehende regionale zerebrale Minderperfusion als primäre Ursache des Brain Fog bei ME/CFS. Kleine Studien mit SPECT, pseudo-continuous arterial spin labeling (PCASL) und ASL-fMRT beschrieben zwar regionale Perfusionsunterschiede, veränderte Erholungsreaktionen und funktionelle Netzwerkveränderungen, zeigten jedoch keine konsistente krankheitsspezifische Hypoperfusionssignatur. Direkter unterstützt wird ein dynamisches Modell, in dem orthostatische Belastung und autonome Dysregulation die zerebrale Perfusionsreserve, Autoregulation und kognitive Belastbarkeit beeinträchtigen. Metabolische und neuroenergetische Mechanismen bleiben plausibel, wurden durch die hier berücksichtigten Studien jedoch nicht direkt nachgewiesen. Insgesamt ist ein multifaktorielles Zusammenspiel aus autonomer Regulation, hämodynamischer Anpassung, neurovaskulärer Kopplung, Netzwerkfunktion und möglicherweise begrenzter metabolischer Belastbarkeit am wahrscheinlichsten.
Question: Brain-Fog bei ME/CFS: Mich würde interessieren, wie robust die Evidenz für die regionale Minderperfusion gegenüber metabolischen und autonomen Mechanismen ist
Read the full reviewThe supplied evidence supports an association between resveratrol and sirtuin-related pathways, particularly SIRT1 and SIRT3, but does not justify describing resveratrol as a universal or consistently direct sirtuin activator. Biochemical and computational studies indicate that resveratrol can enhance SIRT1 activity under specific assay and substrate conditions by stabilizing interactions between SIRT1 and particular peptide substrates (PMID: 26109052; PMID: 27901083). Cellular and animal studies further connect resveratrol with SIRT1-dependent effects involving AMPK, mitochondrial function, inflammation, endothelial signaling, and protein expression. Evidence for SIRT3 includes functional protection in cardiac and intestinal injury models, with benefits lost after SIRT3 deficiency or silencing (PMID: 25527776; PMID: 37858064). However, several findings support indirect pathway modulation, and the physiological relevance of direct SIRT1 activation remains controversial. The cited material does not establish activation of SIRT2, SIRT4, SIRT5, SIRT6, or SIRT7 as a general effect.

Read the full reviewMessenger RNA 3′ untranslated regions (3′ UTRs) regulate transcript stability, localization, translation, surveillance, and degradation through sequence elements, RNA structure, polyadenylation status, and interactions with RNA-binding proteins and noncoding RNAs. Nevertheless, major uncertainties remain regarding how these regulatory features are integrated across cell types, subcellular compartments, developmental states, infections, and cancers. Alternative polyadenylation (APA) generates isoforms with different 3′ UTR lengths and can remove or expose regulatory elements, but the mechanisms determining poly(A)-site selection and the direct consequences of isoform switching remain incompletely defined. Additional unresolved areas include the functions of 3′ UTR-derived RNAs, the molecular basis of localized translation, the regulation of translation termination and RNA surveillance, and the links between altered 3′ UTR architecture and disease phenotypes. This review synthesizes these gaps and emphasizes the need for integrated measurements of RNA sequence, structure, localization, stability, translation, protein binding, and functional perturbation.

Read the full reviewNLRP3 inflammasome activation contributes to experimental inflammatory lung injury through caspase-1 activation, gasdermin D–mediated pyroptosis, and release of interleukin (IL)-1β and IL-18. This review summarizes preclinical evidence for direct and indirect approaches targeting NLRP3-associated pathways. Direct inhibitors include MCC950, nimbolide, bigelovin, and the quinoxalinone compounds QK-3D and QK-3E. Additional strategies modulate upstream or parallel pathways involving mitochondrial metabolism, ROCK2/YAP signaling, NF-κB, Nrf2, Drp1/ROS, endoplasmic-reticulum stress, TXNIP, and autophagy. Across models of lipopolysaccharide (LPS)-induced acute lung injury, acute respiratory distress syndrome (ARDS), radiation-induced lung injury, and experimental silicosis, these interventions reduced inflammatory-cell recruitment, cytokine production, pyroptosis, tissue injury, and pulmonary edema. However, the evidence remains preclinical, and human efficacy, pharmacokinetics, long-term safety, and clinical utility have not been established.

Read the full reviewNLRP3 inhibitors represent a diverse preclinical strategy for suppressing inflammasome-associated cytokine production, pyroptosis, and inflammation. The evidence reviewed here includes established tool compounds, optimized derivatives, direct NLRP3 binders, ATPase inhibitors, and computationally nominated candidates. MCC950 remains a highly characterized reference compound with activity in canonical and noncanonical NLRP3 models, although toxicity concerns limited its clinical development. Subsequent programs have pursued improved tolerability, oral exposure, central nervous system penetration, target engagement, and activity against resistant NLRP3 variants. Compounds including YQ128, JT002, N14, H28, C4, ZAP-180013, Compound A, and AZD4144 have demonstrated varying degrees of cellular, pharmacological, or disease-model validation, whereas NSC828779 remains experimentally unvalidated. Collectively, the material supports continued development of structurally and mechanistically distinct NLRP3 inhibitors while emphasizing the persistent importance of safety, bioavailability, and in vivo validation.

Read the full reviewSpinal implant-associated infections are microbiologically diverse but are dominated by biofilm-forming Gram-positive organisms. Staphylococcus aureus, including methicillin-resistant S. aureus, and coagulase-negative staphylococci, particularly Staphylococcus epidermidis, are consistently prominent. Cutibacterium acnes is especially associated with delayed, chronic, indolent, or clinically subtle infections. Gram-negative bacilli, Enterococcus species, anaerobes, and polymicrobial communities constitute important additional causes, with their frequency influenced by infection timing, anatomic location, and surgical context. Methicillin resistance and recurrent infection are documented, and repeated revision procedures may reveal changing microbial spectra. Because species-level identification can be difficult in low-grade infections and mixed communities are common, intraoperative tissue cultures and, when available, implant-sonication cultures should be obtained during revision procedures (PMID: 35853535).

Read the full reviewCalcium pyrophosphate dihydrate (CPPD) crystal deposition is associated with several spinal abnormalities, including disc calcification, endplate erosion, osteophyte formation, facet inflammation, ligamentous lesions, and atlantoaxial disease. Pathologic and imaging studies show that CPPD may occur within intervertebral discs, annuli, cartilage end plates, and adjacent structures, sometimes in diffuse and multilevel patterns. However, CPPD-related spinal disease should not be equated with ordinary degenerative disc disease (DDD). Crystal deposition may occur without histologic disc degeneration, coexist with established degeneration, or contribute to inflammatory and erosive changes outside the disc. Current evidence is predominantly observational, histopathologic, biochemical, and case-based, and does not establish CPPD as a primary cause of intervertebral disc degeneration (IDD).
