X-ray phase-contrast imaging by grating interferometry has in the past decades been established both at synchrotron radiation sources and at conventional x-ray tubes. Due to the sensitivity to x-ray phase shifting, contrast in soft tissue has been improved significantly and the possibilities to do virtual histology of tissue biopsies are being pioneered. Constraints in the design of a grating inte
Aim: To evaluate the incidence of chromosomal aberrations in apparently isolated ventricular septal defects (VSD), quantify the timing of diagnosis of prenatally diagnosed VSDs, and define the spontaneous closure rate prenatally both in utero and during the first year of life. Materials and methods: Medline, PubMed, and the Cochrane Database Library were searched to identify studies published betw
Jorge Ibargüengoitia is one of the most prominent writers in 20th-century Mexican literature. This study provides an analysis of his narrative in the work Dos Crímenes. The primary objective is to elucidate how the author constructs his narrative threads through the use of irony, which becomes a recurrent tool in his style. To accomplish this, it is proposed that Ibargüengoitia employs different t
Critical constructive feedback (CCF), is said to be a key ingredient in learning. However, if and how learners engage in CCF is rarely studied in collaborative learning situations. This study aims to filling this research gap by analyzing data logs from dyads of middle school students using an educational game in history, evaluating their inclination to dismiss or attend to feedback when making er
Objective: Giant cell arteritis (GCA) is an age-related vasculitis. Prior studies have identified an association between GCA and hematologic malignancies (HMs). How the presence of somatic mutations that drive the development of HMs, or clonal hematopoiesis (CH), may influence clinical outcomes in GCA is not well understood. Methods: To examine an association between CH and GCA, we analyzed sequen
OBJECTIVE: To estimate patient acceptable symptom state (PASS) and treatment failure (TF) threshold values for Work Productivity and Activity Impairment (WPAI) measure and EQ-5D-5L among people with hip or knee osteoarthritis (OA) 3 and 12 months following participation in a digital self-management intervention (Joint Academy®).METHODS: Among the participants, we computed work and activity impairm
Numerous electronic travel aids (ETAs) to increase the mobility of blind or low-vision (BLV) individuals have been proposed. However, the lack of established and well-motivated methods, and of recruiting enough BLV test participants, keeps a successful aid illusory. To combat this, a new aid-agnostic questionnaire focused on mobility, the Desire of Use Questionnaire for Mobility of BLV individuals
Objective: To describe a retroperitoneal transient occlusion of the uterine or internal iliac artery in conjunction with a high-risk evacuation of products of conception. The procedure was performed vaginally, minimally invasively, via vaginal natural orifice transluminal endoscopic surgery. Design: Description of the surgical technique using original video footage. This study was exempted from re
Objective: The aim was to optimize diagnostics for carotid artery calcifications (CACs) on panoramic radiographs (PRs) to identify cardiovascular disease (CVD) by investigating how 4 defined CAC shapes are associated with ultrasound (US) findings indicating CVD. Study Design: The study included 414 participants (802 neck sides) from the Malmö Offspring Dental Study, examined with PRs. The PRs were
Purpose: Recent work has shown MRI is able to measure and quantify signals of phospholipid membrane-bound protons associated with myelin in the human brain. This work seeks to develop an improved technique for characterizing this brain ultrashort- (Formula presented.) component in vivo accounting for (Formula presented.) weighting. Methods: Data from ultrashort echo time scans from 16 healthy volu
Background: Helicobacter pylori (H. pylori) uses various strategies that attenuate mucosal immunity to ensure its persistence in the stomach. We recently found evidence that H. pylori might modulate the natural killer group 2, member 2 (NKG2D) system. The NKG2D receptor and its ligands are a major activation system of natural killer and cytotoxic T cells, which are important for mucosal immunity a
Following green revolution ideologies, smallholder commercialization is promoted as a pathway to African economic transformation. Nonetheless, polices that incentivize commercial production in Ghana affect migrant groups negatively with respect to land tenure. While some migrants are displaced from rented lands, others offer their labour services in exchange for the right to "freely” intercrop on
Liver transplantation is a highly complex, life-saving, treatment for many patients with advanced liver disease. Liver transplantation requires multidisciplinary teams, system-wide adaptations and significant investment, as well as being an expensive treatment. Several metrics have been proposed to monitor processes and outcomes, however these lack patient focus and do not capture all aspects of t
Background: This meta-analysis investigated the effects of enhanced recovery after surgery (ERAS) protocols compared to conventional care on postoperative outcomes in patients aged 70 years or older undergoing pancreatoduodenectomy (PD). Methods: Five databases were systematically searched. Comparative studies with available individual patient data (IPD) were included. The main outcomes were posto
Background: Intact cord resuscitation in the first three minutes of life improves oxygenation and Apgar scores. The practise of intact cord resuscitation implies the umbilical cord still being connected to the placenta for at least one minute while providing temperature control and equipment for resuscitation. Healthcare professionals described practical challenges in providing intact cord resusci
We build a model to predict from first principles the properties of major mergers. We predict these from the coalescence of peaks and saddle points in the vicinity of a given larger peak, as one increases the smoothing scale in the initial linear density field as a proxy for cosmic time. To refine our results, we also ensure, using a suite of ∼400 power-law Gaussian random fields smoothed at ∼30 d
Background and purpose: Motion management techniques are important to spare the healthy tissue adequately. However, they are complex and need dedicated quality assurance. The aim of this study was to create a dynamic phantom designed for quality assurance and to replicate a patient's size, anatomy, and tissue density. Materials and methods: A computed tomography (CT) scan of a cancer patient was u
