A prospective study of predictors of return to work after surgery for ulnar nerve entrapment

Ulnar nerve entrapment at the elbow (UNE) is the second most common compression neuropathy in the upper limb. Immediate return-to-work (RTW) after surgery is seldom possible due to restrictions and recovery demands. We aimed to explore RTW after UNE surgery and investigate factors contributing to variations. A prospective study with patients undergoing primary UNE surgery was conducted. Treatment

Accurate prediction of substitution rates at protein sites with a mutation-selection model

The pattern of substitutions at sites in proteins provides invaluable information about their biophysical and functional importance and what selection pressures are acting at individual sites. Amino acid site rates are typically estimated using phenomenological models where sequence variability is described by rate factors that scale the overall substitution rate in a protein to sites. In this stu

First Resolution of Microlensed Images of a Binary-lens Event

We resolve the multiple images of the binary-lens microlensing event ASASSN-22av using the GRAVITY instrument of the Very Large Telescope Interferometer (VLTI). The light curves show weak binary-lens perturbations, complicating the analysis, but the joint modeling with the VLTI data breaks several degeneracies, arriving at a strongly favored solution. Thanks to precise measurements of the angular

Towards an interoperable perovskite description or how to keep track of 300 perovskite ions

Hybrid perovskites are interesting optoelectronic materials. The perovskite ABX3 structure offers a vast compositional space, and we have identified over 300 perovskite ions. This flexibility enables tuneable properties and has significantly contributed to the success of perovskite optoelectronics. However, this diversity also leads to confusion, ambiguity, and inconsistencies causing challenges f

Experiences of navigating anticipations and anxiety among patients having surgery for peripheral nerve tumours

Peripheral nerve tumours, most commonly schwannomas and neurofibromas, might present significant challenges by eliciting physical symptoms and emotional distress. We aimed to explore patients’ expectations, perceptions, and experiences regarding their diagnosis and the surgical treatment of a nerve tumour in the upper limb. Fourteen adults (10 women, 4 men; age range 35–85) from two Swedish hand s

Hints of a close outer companion to the ultra-hot Jupiter TOI-2109 b

Context. Hot Jupiters (HJs) with close-by planetary companions are rare, with only a handful of them having been discovered so far. This could be due to their suggested dynamical histories, which lead to the possible ejection of other planets. TOI-2109 b is special in this regard because it is the HJ with the closest relative separation from its host star, being separated by less than 2.3 stellar

Development and evaluation of a machine learning prediction model for short-term mortality in patients with diabetes or hyperglycemia at emergency department admission

Background: Patients with diabetes admitted to emergency care face a higher risk of complications, including prolonged hospital stays, admissions to the intensive care unit and mortality. Aim: To develop a machine learning (ML) model to predict 30-day mortality in patients with diabetes admitted to the emergency department (ED). Design and setting: A cohort study utilizing data from all nine ED’s

Exploring potential sex differences in Hirschsprung disease : a national cohort study of diagnostic patterns and early postoperative outcome

Purpose: There are limited data to show how sex impacts the early clinical course of patients with Hirschsprung disease (HSCR). This study aimed to explore potential sex related disparities in the preoperative, surgical, and early postoperative course of HSCR patients. Methods: This retrospective study analyzed data of HSCR patients who underwent pull-through surgery at pediatric surgery centers i

Binding to thrive : Decoding Atopobium spp. interactions with host proteins and immune cells

Objectives: Gram-positive anaerobic cocci are opportunistic pathogens that exploit immune suppression or tissue injury to establish infections. Atopobium spp. are clinically relevant, being linked to bacterial vaginosis, abdominal wounds, pelvic abscesses, and dental infections. While clinical reports describe the involvement in detrimental host conditions, in-depth knowledge is missing to underst

Thorough clinical child psychiatric diagnostic evaluation and validation of the Autism- Tics, ADHD and other comorbidities inventory (A-TAC) in a population-based sample of 9-year-olds

Background: The Autism- Tics, ADHD and other Comorbidities inventory (A-TAC) has been validated in epidemiological data. However, validation against clinical diagnostic assessments in a population-based sample has been lacking, limiting the implications for clinical practice, clinical research and public health decisions. Methods: Study participants were recruited from the longitudinal Child and A

Effects of solution conditions on the self-assembly of the chaperone protein DNAJB6b

Chaperone proteins are essential for maintaining proteostasis. Their main role is to assist with the folding of other proteins and to prevent the aggregation of misfolded proteins. The molecular chaperone DNAJB6b efficiently suppresses amyloid formation of several peptides. This activity may rely on the same physicochemical properties as those driving chaperone self-assembly into large micellar-li

Mineralization of dental tissues and caries lesions detailed with Raman microspectroscopic imaging

Dental caries is the most common oral disease that causes demineralization of the enamel and later of the dentin. Depth-wise assessment of the demineralization process could be used to help in treatment planning. In this study, we aimed to provide baseline information for the development of a Raman probe by characterizing the mineral composition of the dental tissues from large composition maps (6

Subchondral bone plate thickness is associated with micromechanical and microstructural changes in the bovine patella osteochondral junction with different levels of cartilage degeneration

The influence of joint degeneration on the biomechanical properties of calcified cartilage and subchondral bone plate at the osteochondral junction is relatively unknown. Common experimental difficulties include accessibility to and visualization of the osteochondral junction, application of mechanical testing at the appropriate length scale, and availability of tissue that provides a consistent r

Characterisation of airway inflammation and proteomes associated with cystic fibrosis-related diabetes

Background: Cystic fibrosis (CF)-related diabetes (CFRD) is the most common extrapulmonary complication in CF. CFRD is associated with low lung function, but the underlying mechanisms are poorly understood. The aim of the present study was to compare airway inflammation and the airway proteome in people with CF (pwCF) with and without CFRD.Methods: Sputum samples from pwCF were analysed for neutro

Development of a leucine-rich repeat-containing protein 15-targeted radio-immunotheranostic approach to deplete pro-tumorigenic mechanisms and immunotherapy resistance

Leucine-rich repeat containing 15 (LRRC15) has emerged as an attractive biomarker and target for cancer therapy. Transforming growth factor-β (TGFβ) induces the expression of this plasma membrane protein specifically in aggressive and treatment resistant tumor cells derived from mesenchymal stem cells, with minimal expression observed in non-neoplastic tissues. We have developed a humanized monocl
