Ceftolozane/tazobactam disrupts Pseudomonas aeruginosa biofilms under static and dynamic conditions.

Background: Pseudomonas aeruginosa biofilms limit the efficacy of currently available antibacterial therapies and pose significant clinical challenges. Pseudomonal biofilms are complicated further when other markers of persistence such as mucoid and hypermutable phenotypes are present. There is currently a paucity of data regarding the activity of the newer β-lactam/β-lactamase inhibitor combination ceftolozane/tazobactam against P.

The Fate of the Frozen Bone Flap: Quantitative and Volumetric Assessment Following Cranioplasty Using the Autologous Bone Flap.

Objective: The pattern, rate, and natural history of bone flap resorption following cranioplasty with frozen, autologous bone flap has not been fully defined. The authors sought to quantify the progression and natural history of bone flap resorption.

Methods: Patients who had craniectomy and delayed cranioplasty with stored, frozen bone flap between 2012 and 2022 were included in this study.

Evaluation of a combined model of Polygenic Risk Score and mismatch repair genes in the association of colorectal cancer for Norwegian cohort.

Background And Aims: Recent studies have shown that combining polygenic risk score (PRS) and carrier status for germline pathogenic variants in colorectal cancer (CRC) susceptibility genes (e.g. ) may increase the success of predicting CRC.

Aortic and arterial manifestations and clinical features in -related heritable thoracic aortic disease: results from the Montalcino Aortic Consortium.

Background: Pathogenic variants in may lead to a syndromic genetic aortopathy. Heritable thoracic aortic disease (HTAD) and arterial events may occur in -related disease but there are limited outcomes data on vascular events in this condition.

Methods: Clinical data, phenotypical features and aortic outcomes in individuals with pathogenic/likely pathogenic (P/LP) variants enrolled in the Montalcino Aortic Consortium registry were reviewed.

Arteriovenous malformations treated by stereotactic radiosurgery - Review of an Australian single centre's experience.

Linear accelerator (LINAC) stereotactic radiosurgery (SRS) is a specialised treatment used for various brain conditions, including arteriovenous malformations (AVMs). This paper investigates the obliteration rate of AVMs treated by the LINAC-based facility at Prince of Wales Hospital, defines factors influencing obliteration rate, time to obliteration and complications post-SRS. A retrospective audit review of patient notes sourced from electronic medical records was conducted.

Agreement between clinical criteria and quantitative polymerase chain reaction for diagnosing scabies in Auckland children.

Aim: We sought to determine the degree of agreement between clinical and laboratory methods for diagnosing scabies in school-aged children.

Methods: Clinical information and samples were collected from children aged 7 months to 14 years attending educational institutions in Auckland, New Zealand. Two methods determined scabies status: the International Alliance for the Control of Scabies clinical criteria (IACS) and quantitative polymerase chain reaction (qPCR).

Disparities in Body Mass Between Cave and Culvert Hibernacula in Georgia, USA.

The tricolored bat (), once common in the eastern United States, has experienced significant mortality due to white-nose syndrome (WNS), a fungal disease that primarily affects bats hibernating in caves and mines. In coastal regions of the southeastern United States, where caves and mines are scarce, tricolored bats often use roadway culverts as hibernacula. However, WNS infection dynamics in culverts are poorly understood.

The effect of haemoglobin and blood transfusion on preterm infant gut perfusion and injury.

Introduction: There is significant uncertainty regarding the role that anaemia or red blood cell transfusion (RBCT) plays in the development of gut injury in preterm infants. This study evaluated Near Infrared Spectroscopy (NIRS) together with a range of known biomarkers of gut inflammation to identify their relationship with anaemia and RBCT.

Method: A prospective observational study of preterm infants born at <30 weeks gestation was conducted from birth until either 36 weeks post conceptional age or discharge home.

Safety and efficacy of mitapivat in sickle cell disease (RISE UP): results from the phase 2 portion of a global, double-blind, randomised, placebo-controlled trial.

Background: Sickle cell disease, a debilitating, inherited haemolytic anaemia with premature morbidity and mortality, affects millions globally. Mitapivat, a first-in-class, oral, allosteric activator of pyruvate kinase, improves red blood cell survival by increasing ATP and diminishes sickling by decreasing 2,3-diphosphoglycerate. We aimed to evaluate the efficacy and safety of mitapivat in patients with sickle cell disease.

Influence of medical conditions on the diagnostic accuracy of plasma p-tau217 and p-tau217/Aβ42.

Introduction: Blood-based biomarkers (BBMs) can enable early detection of brain amyloid beta (Aβ) pathology in cognitively unimpaired individuals. However, the extent to which common medical conditions affect biomarker performance remains unclear.

Methods: Participants (n = 348) included individuals without cognitive impairment.

The dynamics of hematopoiesis over the human lifespan.

Over a lifetime, hematopoietic stem cells (HSCs) adjust their lineage output to support age-aligned physiology. In model organisms, stereotypic waves of hematopoiesis have been observed corresponding to defined age-biased HSC hallmarks. However, how the properties of hematopoietic stem and progenitor cells change over the human lifespan remains unclear.

Rationale and design of the PE-TRACT trial: A multicenter randomized trial to evaluate catheter-directed therapy for the treatment of intermediate-risk pulmonary embolism.

Background: The optimal management of patients with intermediate-risk pulmonary embolism (PE), who have right heart dysfunction (determined by a combination of imaging and cardiac biomarkers) but a normal blood pressure, is uncertain. These patients suffer from reduced functional capacity and a lower quality of life over the long-term, despite use of anticoagulant therapy. Catheter-directed therapy (CDT) is a promising treatment for acute PE that rapidly removes thrombus and potentially improves cardiac dysfunction.

Alkaloids are associated with increased microbial diversity and metabolic function in poison frogs.

Shifts in host-associated microbiomes can impact both host and microbes. It is of interest to understand how perturbations, like the introduction of exogenous chemicals, impact microbiomes. In poison frogs (family Dendrobatidae), the skin microbiome is exposed to alkaloids that the frogs sequester for defense.

Continuously tuneable single electrode pair liquid crystal optical vortex generators.

In this work, we demonstrate the use of two-photon polymerization direct laser writing in the production of continuously tuneable optical vortex beam (OV) generators in a liquid crystal (LC) layer sandwiched between glass substrates. Results are presented that show how an OV generator can be inscribed into a 20 μm-thick LC layer and how the order of the OV beam can be tuned with the application of a voltage. Importantly, only a single pair of electrodes is needed to tune the order of the vortex as the required phase profile is generated through the 3D structuring of the polymer network using the laser writing process.
