Intravascular Ultrasound Assessment of Distal Trans-Radial Access in Patients Undergoing Percutaneous Coronary Intervention.

Background: Distal trans-radial access (dTRA) for percutaneous coronary interventions (PCI) is increasingly gaining attention due to its potential to mitigate radial artery occlusion (RAO). However, a comprehensive understanding of the mechanical impact of the devices on the radial artery (RA) wall remains limited. Using a complete intravascular ultrasound (IVUS) evaluation of the RA, including also the vascular access site, we aimed to evaluate all the consequences related to the catheterization on the RA wall, starting from the vascular access, comparing conventional sheath and sheathless approaches.

Hybrid open-endovascular onyx embolization of spinal type IVb perimedullary spinal arteriovenous fistula through direct posterior spinal vein access: A case report.

Background: Spinal arteriovenous fistulas (SAVFs) are direct communication between arteries and veins without intervening abnormal vessel nidus, which often results in venous congestion and spinal cord dysfunction. Ventrally located SAVF can be challenging to treat through traditional open or endovascular approaches.

Case Description: We describe a hybrid (open/endovascular) procedure in a 72-year-old male with a Takai Type IVb SAVF presenting with paraparesis and sphincter dysfunction.

Role of physiology in the management of multivessel disease among patients with acute coronary syndrome.

Multivessel coronary artery disease (CAD), defined as ≥50% stenosis in 2 or more epicardial arteries, is associated with a high burden of morbidity and mortality in acute coronary syndrome (ACS) patients. A salient challenge for managing this cohort is selecting the optimal revascularisation strategy, for which the use of coronary physiology has been increasingly recognised. Fractional flow reserve (FFR) is an invasive, pressure wire-based, physiological index measuring the functional significance of coronary lesions.

Effects of Melatonin on Exercise-Induced Oxidative Stress in Adults with Obesity Undergoing a Multidisciplinary Body Weight Reduction Program.

Obesity is characterized by increased oxidative stress, which, in a vicious circle, promotes chronic low-grade inflammation. Melatonin, a well-documented antioxidant, might be useful as a supplement to enhance the cardiometabolic benefits of any body weight reduction program (BWRP). The present study aimed to evaluate the post-exercise oxidative stress and inflammation in a group of subjects with obesity treated with melatonin (2 mg/die) or placebo, undergoing a 2-week BWRP, with the administration of a single bout of acute exercise at the start and the end of the protocol (G1-G15).

Impact of Previous Surgery and/or Radiation Therapy on Endoscopic Reconstruction Outcomes.

Background And Objectives: The impact of prior local therapies, including radiation and surgery, on reconstruction outcomes after endonasal surgery is currently not well known. Reconstruction nuances in the preoperative setting merit further evaluation to avoid potential postoperative complications that can hinder overall tumor management and negatively impact patient outcome. We sought to determine whether prior treatments increase risk of reconstruction-related postoperative morbidity and to evaluate the effectiveness of our current treatment paradigm for skull base reconstruction.

Coronary Artery Plaque Phenotype and 5-Year Clinical Outcomes in Older Patients with Non-ST Elevation Acute Coronary Syndrome.

Background: Lesions with thin-cap fibroatheroma (TCFA), small luminal area and large plaque burden (PB) have been considered at high risk of cardiovascular events. Older patients were not represented in studies which demonstrated correlation between clinical outcome and plaque characteristics. This study aims to investigate the prognostic role of high-risk plaque characteristics and long-term outcome in older patients presenting with non-ST elevation acute coronary syndrome (NSTEACS).

Acute total hip arthroplasty with a highly-porous multi-holes cup in elderly patients after traumatic acetabular fracture: A case series and literature review.

There are no general guidelines for the treatment of acetabular fractures. Open reduction and internal fixation is advised in young and active patients, while acute total hip arthroplasty (THA) is recommended for elderly patients in order to allow immediate weight bearing. Various THA systems have been reported.

[HIF-ɑ: New Target For Treatment of Renal Anemia. Molecular Aspects and Activation of Pathway HREs].

Roxadustat, recently approved, is a hypoxia-inducible factor prolyl hydroxylase inhibitor that has demonstrated favorable safety and efficacy in the treatment of renal anemia. This article reviews main features and possible effects by activation of pathway sequences HREs.

The Role of Dietary Intake in the Weight Loss Outcomes of Roux-en-Y Gastric Bypass and Sleeve Gastrectomy: A Systematic Review and Meta-analysis.

The relationship between postoperative dietary intake and weight loss after bariatric surgery remains unclear. We performed a systematic review and meta-analysis of studies published between January 2000 and May 2023, reporting weight loss outcomes, and dietary intake before and after Roux-en-Y gastric bypass and sleeve gastrectomy. A total of 42 studies were included.

Novel Rickettsia and host records for argasid ticks, including Alveonasus cooleyi, on wild mammals in Baja California, Mexico.

We conducted surveillance of mammals to investigate their associations with argasid ticks and tick-borne pathogens. During 2021, a total of 20 wild carnivores and 57 lagomorphs were sampled, and 39 argasid ticks belonging to two species were collected. All mammals and ticks were tested by molecular assays to detect Borrelia and Rickettsia infections.

Coronary physiology assessments: historical overview and future challenges.

Coronary physiological assessment has garnered extensive application in managing patients with coronary artery disease, encompassing both acute and chronic scenarios. Beyond the historical purpose as tool to define the hemodynamic significance of a given artery lesion, coronary artery physiology allows for a complete investigation of epicardial and microvascular circulation. The longitudinal assessment of the distribution pattern of coronary disease based on pressure wire technology provides crucial information to define the best management and procedural planning.

The association of inflammatory biomarkers and long-term clinical outcomes in older adults with non-ST elevation acute coronary syndrome.

Background: The prognostic significance of inflammatory markers on the long-term risk of major adverse cardiovascular and cerebrovascular events (MACCE) in older NSTEACS patients remains unclear.

Methods: NSTEACS patients aged 75 and older were recruited to the multicentre cohort study Improve Cardiovascular Outcomes in High-Risk PatieNts with Acute Coronary Syndrome (ICON1). Inflammatory markers including interleukin-6 (IL-6), myeloperoxidase (MPO), high-sensitivity C-reactive protein (hsCRP), fibrinogen and tumor necrosis factor-alpha (TNF-α) were collected at baseline.

Exploring the underwater life in transitional environments: Benthic foraminifera, ostracods, and dinoflagellate cysts - Biotic trends and EcoQS assessment in the Mar Piccolo of Taranto (Ionian sea, southern Italy).

Coastal areas have historically thrived as centers of human activities due to their resources, economic opportunities, and natural allure. The rapid growth of coastal populations has however brought forth a multitude of challenges to tackle, with pollution emerging as a significant and far-reaching issue. Our study focuses on the Mar Piccolo of Taranto (Ionian Sea, Southern Italy), a lagoon-like coastal basin (separated in two sub-basins) that, since decades, has been heavily affected by human activities and aquaculture, leading to environmental deterioration.

The role of systemic therapy in advanced skull base chordomas: overview of the current state and the MD Anderson protocol.

The role of systemic therapy in primary or advanced and metastatic chordoma has been traditionally limited because of the inherent resistance to cytotoxic therapies and lack of specific or effective therapeutic targets. Despite resection and adjuvant radiation therapy, local recurrence rates in clival chordoma remain high and the risk of systemic metastases is not trivial, leading to significant morbidity and mortality. Recently, molecular targeted therapies (MTTs) and immune checkpoint inhibitors (ICIs) have emerged as promising therapeutic avenues in chordoma.

Tackling obesity while preventing obesity stigma.

Obesity is a significant public health problem. Prevalence is rising in children and young people, with lifelong health impacts and implications for paediatric clinical practice. Obesity stigma is increasingly acknowledged as a problem within health services.

Integrating microbial abundance time series with fermentation dynamics of the rumen microbiome via mathematical modelling.

The rumen represents a dynamic microbial ecosystem where fermentation metabolites and microbial concentrations change over time in response to dietary changes. The integration of microbial genomic knowledge and dynamic modelling can enhance our system-level understanding of rumen ecosystem's function. However, such an integration between dynamic models and rumen microbiota data is lacking.

Non-invasive vascular measures as prognostic predictors for older patients with non-ST elevation acute coronary syndrome.

Background: Adverse cardiac events are common in older patients with non-ST elevation acute coronary syndrome (NSTEACS), yet prognostic predictors are still lacking. This study investigated the long-term prognostic significance of non-invasive measures including endothelial function, carotid intima-media thickness (CIMT), and vascular stiffness in older NSTEACS patients referred for invasive treatment.

Methods: NSTEACS patients aged 75 years and older recruited to a multicentre cohort study (NCT01933581) were assessed for baseline endothelial function using endoPAT logarithm of reactive hyperemia index (LnRHI), CIMT using B-mode ultrasound, and vascular stiffness using carotid-femoral pulse wave velocity (cfPWV).
