Medin and transthyretin: a new amyloid double act in the aortic wall and valves.

Background: Cross-seeding and co-assembly of multiple amyloid species are increasingly recognised in various organs and amyloidoses. Medin and wild-type transthyretin (TTR) both form age-related amyloid deposits and have been identified within the aortic wall. Given the emerging role of amyloid in aortic disease, this study investigates the potential colocalisation of TTR and medin in the aorta.

Preoperative Mechanical Ventilation Prior to Surgical Repair for Type A Aortic Dissection: Incidence, Risk, and Outcomes.

Objectives: Several conditions associated with type A aortic dissection may require preoperative invasive mechanical ventilation (IMV). The current literature lacks data on this subset of patients' prevalence and postoperative outcomes. This study aims to investigate this unexplored issue in a multicenter European registry.

Outcome after day- and nighttime surgery for acute type A aortic dissection.

Objectives: We aimed to investigate the differences in early and late outcomes after daytime compared to nighttime surgery for type A aortic dissection.

Methods: From 2005 to 2021, patients undergoing surgery for type A aortic dissection at 18 European centres participating in the European registry of type A aortic dissection were included in this study. Based on the time of procedure, patients were allocated into groups (8 a.

Kidney protection during surgery on the thoracoabdominal aorta: a systematic review.

Objectives: Acute kidney injury (AKI) is a common consequence of surgical repair of the thoraco-abdominal aorta (TAA). Perfusion techniques aim to facilitate renal protection through oxygenation or hypothermia. This systematic review assesses renal and mortality outcomes by perfusion techniques to evaluate their ability to provide effective kidney protection.

Carotid artery dissection and neurological complications after surgery for type 1 aortic dissection.

Background: Data on the prognostic impact of type A aortic dissection involving the common carotid arteries (CCAs) are scarce.

Methods: Data on the status of the CCAs were available in 1106 patients who underwent surgery for acute DeBakey type 1 aortic dissection who were recruited in a retrospective, multicentre European registry, that is, the ERTAAD. Postoperative neurological complications were defined as ischaemic stroke, haemorrhagic stroke and/or global brain ischaemia.

Extent of surgical repair and outcomes after surgery for type A aortic dissection.

Background: Acute Stanford type A aortic dissection is a severe emergency condition that, if left untreated, is associated with a high mortality rate. The extent of surgical repair may impact the outcomes of these patients.

Method: Patients operated for acute type A aortic dissection from a multicentre European registry were included.

Survival after surgery for acute type A aortic dissection in octogenarians.

Objective: To evaluate the benefits of surgical repair acute type A aortic dissection (ATAAD) on survival of octogenarians.

Methods: Patients who underwent surgery for acute ATAAD from the multicenter European Registry of Type A Aortic Dissection (ERTAAD) were the subjects of the present analysis.

Results: 326 (8.

Comprehensive analysis of the Kinetoplastea intron landscape reveals a novel intron-containing gene and the first exclusively trans-splicing eukaryote.

Background: In trypanosomatids, a group of unicellular eukaryotes that includes numerous important human parasites, cis-splicing has been previously reported for only two genes: a poly(A) polymerase and an RNA helicase. Conversely, trans-splicing, which involves the attachment of a spliced leader sequence, is observed for nearly every protein-coding transcript. So far, our understanding of splicing in this protistan group has stemmed from the analysis of only a few medically relevant species.

The David Versus the Bentall Procedure for Acute Type A Aortic Dissection.

: Type A aortic dissection (TAAD) is a life-threatening condition which requires prompt diagnosis and surgical treatment. When TAAD involves the aortic root, aortic valve-sparing or Bentall procedures are the main surgical treatment options. The subjects of this analysis were 3735 patients included in the European Registry of Type A Aortic Dissection (ERTAAD).

Malperfusion syndrome in patients undergoing repair for acute type A aortic dissection: Presentation, mortality, and utility of the Penn classification.

Background: The current study aims to report the presentation of the malperfusion syndrome in patients with acute type A aortic dissection admitted to surgery and its impact on mortality.

Methods: Data were retrieved from the multicenter European Registry of Type A Aortic Dissection. The Penn classification was used to categorize malperfusion syndromes.

Associations between central and brachial blood pressure in patients with hypertension and aortovascular disease: Implications for clinical practice.

Central blood pressure (CBP) measurements, compared to brachial blood pressure (bBP), offer a superior predictive accuracy for aortovascular disease outcomes. This emphasises the distinctiveness of central hemodynamic metrics such as CBP, measuring the pressure directly exerted from the cardiac muscle to the major arteries, and provides a more direct assessment of cardiovascular workload than bBP, which measures the pressure against peripheral artery walls. This review synthesises findings evaluating the correlation between CBP and key aortovascular disease markers.

Pass the boron: benzoxaboroles as antiparasite drugs.

The development of new drug modalities has been facilitated recently by the introduction of boron as a component of organic compounds, and specifically within a benzoxaborale scaffold. This has enabled exploration of new chemical space and the development of effective compounds targeting a broad range of morbidities, including infections by protozoa, fungi, worms, and bacteria. Most notable is the recent demonstration of a single oral dose cure using acoziborole against African trypanosomiasis.

Stroke outcomes following cardiac and aortic surgery are improved by the involvement of a stroke team.

Objectives: Post-cardiac and aortic surgery stroke is often underreported. We detail our single-centre experience the following introduction of comprehensive consultant-led daily stroke service, to demonstrate the efficacy of a stroke team in recovery from stroke following cardiac and aortic surgeries.

Methods: This retrospective, single-centre observational cohort study analysed consecutive patients undergoing cardiac and aortic surgery at our institution from August 2014 to December 2020.

Identification and Validation of Compounds Targeting Leucyl-Aminopeptidase M17.

Leishmaniasis is a neglected tropical disease; there is currently no vaccine and treatment is reliant upon a handful of drugs suffering from multiple issues including toxicity and resistance. There is a critical need for development of new fit-for-purpose therapeutics, with reduced toxicity and targeting new mechanisms to overcome resistance. One enzyme meriting investigation as a potential drug target in is M17 leucyl-aminopeptidase (LAP).

A lineage-specific protein network at the trypanosome nuclear envelope.

The nuclear envelope (NE) separates translation and transcription and is the location of multiple functions, including chromatin organization and nucleocytoplasmic transport. The molecular basis for many of these functions have diverged between eukaryotic lineages. , a member of the early branching eukaryotic lineage Discoba, highlights many of these, including a distinct lamina and kinetochore composition.

Diameter and dissection of the abdominal aorta and the risk of distal aortic reoperation after surgery for type A aortic dissection.

Background: Surgery for Stanford type A aortic dissection (TAAD) is associated with an increased risk of late aortic reoperations due to degeneration of the dissected aorta.

Methods: The subjects of this analysis were 990 TAAD patients who survived surgery for acute TAAD and had complete data on the diameter and dissection status of all aortic segments.

Results: After a mean follow-up of 4.
