Measuring asynchrony between the thorax and abdomen during sleep provides information about inspiratory effort and upper airway obstruction in children, aiding in the diagnosis of obstructive sleep apnea (OSA). This study aimed to define a normative range for thoracoabdominal asynchrony (TAA) in healthy children by studying polysomnographies of 113 children aged 10–13 years. The percentage of tota
Background and purpose — Total knee arthroplasties (TKA) affect the mechanical loading of the knee joint and may be associated with changes in bone mineral density (BMD). We aimed to evaluate adaptive periprosthetic BMD after cemented and uncemented TKA. Methods — This is a secondary report of an earlier published RCT. Patients receiving cemented (n = 31) or uncemented (n = 32) TKA were included i
Background – The Rosenberg Self-Esteem Scale (RSES) is one of the most widely used measures of global self-esteem. While its psychometric properties have been extensively studied using classical test theory, limited evidence exists on its performance under modern test theory approaches. Aim – To evaluate the psychometric properties of the RSES using Rasch analysis in a sample of Swedish adolescent
Background: Emerging and re-emerging arboviral infections are a risk to blood safety. We conducted an international survey on how blood establishments respond to current and future arbovirus threats. Study Design and Methods: A questionnaire on arbovirus donor deferral strategies, pathogen reduction, and donation screening was distributed to members of the International Society of Blood Transfusio
Objective: To evaluate whether a structured 2-day micro-ultrasonography (microUS) training curriculum improves diagnostic performance and management decisions for clinically significant prostate cancer (csPCa) detection in novice readers. Subjects and Methods: A total of 20 participants with limited microUS experience completed the Mannheim Micro-Ultrasound Curriculum, comprising didactic modules,
Internal head- and neck lymphedema (I-HNL) is a common side effect after head and neck cancer treatment, but the current assessment and rehabilitation practices remain unclear. The purpose of this study was to explore how Swedish speech and language pathologists (SLPs), physiotherapists (PTs), and lymphedema therapists (LTs) assess and treat I-HNL and how they perceive their competence in doing so
Aim: We examined how lower limb muscle tone was related to age, sex, Gross Motor Function Classification System (GMFCS) level, and the cerebral palsy (CP) subtype in Swedish children with CP. Methods: This registry-based cohort study from 2023 to 2024 used data on all 3 216 children aged 1–15 from the Swedish follow-up program and national CP Registry. Muscle tone was assessed with the Ashworth Sc
Efter alla försök att stoppa användandet av bengaler är svenska supportrar nu mer organiserade. Om polis och politiker planerar att slå till igen bör de fundera över hur folket bidrar till byggandet av fotbollstraditioner, skriver debattören.
Cutting tools are generally subjected to harsh environments, such as high temperatures and pressures, during machining operations. In recent years, the introduction of surface engineering methods on CVD-coated carbide tools has led to significant improvements in their machining performance. However, the interplay between surface engineering process parameters and the resulting surface integrity of
This study examined developmental trajectories of vertical jump performance in young female basketball and volleyball players using Bayesian multilevel modeling. Eighty-one Brazilian female athletes (basketball: n=[jls-end-space/]46; volleyball: n=[jls-end-space/]35) aged 11-18 years were assessed between 2016-2024 in a mixed longitudinal design. Models examined longitudinal age-related changes in
Background: Artificial ultraviolet radiation (UVR) from solarium use has been linked to melanoma in some studies, while others report lower overall mortality. Whether melanoma risk is due to solarium use itself or to associated behaviors indicating intermittent solar overexposure remains unclear. Methods: The Melanoma of Southern Sweden (MISS) cohort included ~ 29,000 women enrolled in 1990 and fo
Purpose: To determine the molecular cause of the two epithelial recurrent erosion dystrophies, Dystrophia Smolandiensis and Dystrophia Helsinglandica, and to identify phenotypic differences between the two conditions. Methods: DNA samples and clinical data from structured interview records were obtained from the Swedish families in which Dystrophia Smolandiensis and Dystrophia Helsinglandica were
Inadequate bowel preparation remains a major barrier to high-quality colonoscopy, with taste aversion representing a common yet under-recognized contributor to poor tolerability of the bowel preparation. Current strategies primarily aim to improve palatability through formulation changes or dosing regimens. This paper proposes a novel, hypothesis-driven approach: transient pharmacologic suppressio
Background: Cobalt is a well-established cause of allergic contact dermatitis (ACD), but data on the skin absorption, toxicity, and immunological effects of cobalt nanoparticles (CoNPs) remain limited. Given the increasing use of nanomaterials in industry and medicine, understanding how cobalt speciation affects skin immune activation is of growing clinical relevance. Methods: Fourteen cobalt-alle
Background: Optimal treatment of T1 rectal cancer (RC) remains to be determined. The aim of this study was to compare recurrence rates after transanal endoscopic microsurgery (TEM) and surgical resection according to risk groups. Material and methods: This registry-based nationwide cohort study collected data on patients diagnosed with pT1 RC undergoing TEM or surgical resection (January 2009–Dece
Central parts of the debate between theories of consciousness concern the proposed mechanism rendering a previously unconscious state X conscious. Here, I introduce a question that comes immediately before, namely why it is X-rather than some other unconscious state Y-that gets to enter the mechanism and become conscious. This is the selection problem: accounting for the mechanism that selects whi
Purpose: The aim of this exploratory study was to investigate different aspects of attitudes to intimate partner violence against women (IPVAW) among university students in Sweden, and whether those attitudes are related to students´ willingness to intervene in cases of IPVAW. Gender differences related to IPVAW attitudes and willingness to intervene were examined. Methods: The study was based on
Introduction – Adolescent depression poses a major public health concern with substantial clinical and societal implications. Both internet-delivered cognitive behavioural therapy (ICBT) and internet-delivered psychodynamic therapy (IPDT) have shown efficacy, but questions remain regarding long-term efficacy and cost-effectiveness. The present study presents a 12-month follow-up and cost-compariso
