Pulmonary abscess is a rare but serious condition in pediatric patients, caused by severe pulmonary infection that leads to tissue destruction and necrosis. It can be classified as primary or secondary depending on the cause. Establishing an etiology in pediatric pulmonary abscesses is challenging, underscoring the essential role of advanced imaging techniques, such as computed tomography, in achieving an accurate diagnosis and differentiating among various conditions that may mimic lung abscess.

Purpose: Current technologies to define the zone of acute peripheral nerve injury intraoperatively are limited by surgical experience, time, cumbersome electrodiagnostic equipment, and interpreter reliability. In this pilot study, we evaluated a real-time, label-free optical technique for intraoperative nerve injury imaging. We hypothesize that fluorescence lifetime imaging (FLIm) will detect a difference between the time-resolved fluorescence signatures for acute crush injuries versus uninjured segments of peripheral nerves in sheep.

One of the key processes that forms the basis of fertilisation is the tight interaction between sperm and egg. Both sperm and egg proteomes are known to evolve and diverge rapidly even between closely related species. Understanding the sperm proteome therefore provides key insights into the proteins that underpin the mechanisms involved during fertilisation and the fusion between sperm and egg, and how they can differ across individuals of the same species.

(1) Background: Since the discovery of antibiotics in the first half of the 20th century, humans have abused this privilege, giving rise to antibiotic-resistant pathogens. Recent research has brought to light the use of antimicrobial peptides in polymers, hydrogels, and nanoparticles (NPs) as a newer and safer alternative to traditional antibiotics. (2) Methods: This review article is a synthesis of the scientific works published in the last 15 years, focusing on the synthesis of polymers with proven antimicrobial properties.

Verifying patients' position and internal anatomical changes are important steps in the radiotherapy of rectal cancer. Cone Beam Computed Tomography (CBCT) is an advanced imaging method that allows for the quantification of these modifications, ensuring the delivery of radiation dose to the tumor volume, while protecting surrounding organs at risk. The aim of this review is to discuss and analyze the benefits offered by this method of imaging on board the linear accelerator.

The corrosion behavior of the TiTaNbZrAg alloys with different amounts of tantalum (0%, 10% and 20%) and with distinct surface topography (smooth and rough) was investigated in phosphate buffer solution (PBS) for long-time immersion (1000 h). By this approach, we expect to bring about new insights into the influence of both the amount of Ta in the alloy composition and the surface topography on the corrosion behavior of the Ti-based alloys. The corrosion resistance was studied by Open Circuit Potential (OCP), Potentiodynamic Polarization (PP), and Electrochemical Impedance Spectroscopy (EIS).

Background: Persistent inequities in breast cancer outcomes exist. Understanding women's experiences along the care pathway is the first step to finding solutions to tackle these inequities.

Methods: Secondary data analysis of the 2017/2018 English National Cancer Patient Experience Survey (n = 25,408) using logistic regression to explore inequities in care experience by sociodemographic factors (age, ethnicity, socioeconomic position, sexual orientation) across 59 survey questions.

Background: Cardiac substructures are critical organs at risk in left-sided breast cancer radiotherapy being often overlooked during treatment planning. The treatment technique plays an important role in diminishing dose to critical structures. This review aims to analyze the impact of treatment- and patient-related factors on heart substructure dosimetry and to identify the gaps in literature regarding dosimetric reporting of cardiac substructures.

Medical oncology, through conventional chemotherapy as well as targeted drugs, remains an important component of cancer patient management, particularly for systemic disease. Despite advances in all areas of medical oncology, certain challenges persist in the form of drug resistance and severe normal tissue toxicity. These unwanted effects can be counteracted through a patient-tailored treatment approach, which in chemotherapy is translated as pharmacogenomics.

Treatment planning parameters in radiotherapy are key elements that dictate the success of treatment outcome. While some parameters are commonly evaluated irrespective of cancer type, others are site-dependent and strongly patient specific. Given the critical influence of planning parameters on personalized therapy, the aim of this study was to evaluate the correlations between the dosimetric indices (conformity, homogeneity and mismatch indices) related to tumor coverage and the patient-specific parameters which encompass parameters pertaining to organs at risk (widths and lengths of heart and ipsilateral lung included in treatment fields, mean/maximum doses to heart, ipsilateral lung, left anterior descending aorta and contralateral breast) and tumor volume.

Cardio-oncology is lately gaining more attention due to radiation-induced cardiac events reported by a very large number of studies. In view of this, the current overview of the literature aimed to encompass all studies from the past 15 years to assess changes in cardiac dose due to treatment evolution, as well as the changes in treatment planning customs to incorporate not only the heart as a whole but also cardiac substructures. Modern treatment techniques, particularly proton therapy, offers superior cardiac sparing compared to more established radiotherapy, for all evaluated tumor sites.

  • The study focuses on improving radiotherapy for oligometastatic lung cancer by proposing a new calibration procedure for the PTW Octavius 1600SRS detector array, specifically in the context of stereotactic body radiation therapy (SBRT) using flattening filter free (FFF) beams.
  • The cohort included 20 patients treated with SBRT delivering a total dose of 50 Gy in five fractions, and the calibration method utilized only one factor at a maximum dose rate for the FFF photon beam while ensuring high dosimetric accuracy through the RTOG 0915 protocol.
  • Results showed strong clinical outcomes with high gamma passing rates of 98.93% and 99

Intravascular ultrasound and optical coherence tomography are used with increasing frequency for the care of coronary patients and in research studies. These imaging tools can identify culprit lesions in acute coronary syndromes, assess coronary stenosis severity, guide percutaneous coronary intervention (PCI), and detect vulnerable plaques and patients. However, they have significant limitations that have stimulated the development of multimodality intracoronary imaging catheters, which provide improvements in assessing vessel wall pathology and guiding PCI.

The aim of this work is to deliver an all-in-one package that contains both the part where the pathologist can manipulate the data as well as predefined models, altogether with the digital pathology interface with a comprehensive component that provides traceability between the identified leucocytes and the underlying possible outcomes of the potential disease. The aim is to directly provide the number of leucocytes and the mass of the cell, only from the image, with minimal intervention from the pathologist, necessary to have a PoC (Proof of Concept) or a prototype. The model was trained on a dataset of around 20,000 models, and the achieved accuracy was approximately 85%.
