Objectives: To evaluate the impact of the 2018 switch from PCV13 to PCV10 in Sweden’s childhood immunisation programme on the serotype distribution of Streptococcus pneumoniae.MethodsRespiratory tract (RT) S. pneumoniae isolates (n=1615; 2020–2023) were serotyped, tested for antimicrobial susceptibility and compared with invasive pneumococcal disease (IPD) isolates (n=397) and PCV13-era data (2016
Electrostatic energy plays a pivotal role in the minimization of the free energy of self-assembling oppositely charged ions. This is a fundamental principle that guides the formation of aggregates and the separation of phases characterized by a stoichiometric balance between the opposite charges. However, this study unveils the self-assembly of catanionic nanotubes from a mixture of oppositely cha
An abdominal aortic aneurysm (AAA) is defined as aortic diameter ≥30 mm measured by ultrasound. AAA prevalence increases with age and is higher in men, but has decreased during the last decades, related to lower smoking rates. Tobacco smoking, concomitant atherosclerosis, arterial hypertension, and family history are the most common risk factors. AAA has atherosclerotic, inflammatory, apoptotic, a
Amyloid formation is linked to devastating neurodegenerative diseases, motivating detailed studies of the mechanisms of amyloid formation. For Aβ, the peptide associated with Alzheimer’s disease, the mechanism and rate of aggregation have been established for a range of variants and conditions in vitro and in bodily fluids. A key outstanding question is how the relative stabilities of monomers, fi
Photo- and charge-carrier-induced ion migration is a major challenge when utilizing metal halide perovskite semiconductors for optoelectronic applications. For mixed iodide/bromide perovskites, the compositional instability due to light- or electrical bias induced phase-segregation restricts the exploitation of the entire bandgap range. Previous experimental and theoretical work suggests that exci
The nucleolar surveillance pathway monitors nucleolar integrity and responds to nucleolar stress by mediating binding of ribosomal proteins to MDM2, resulting in p53 accumulation. Inappropriate pathway activation is implicated in the pathogenesis of ribosomopathies, while drugs selectively activating the pathway are in trials for cancer. Despite this, the molecular mechanism(s) regulating this pro
We propose a continuous variable quantum state tomography protocol of electrons which result from the ionization of atoms or molecules by the absorption of extreme ultraviolet light pulses. Our protocol is benchmarked against a direct calculation of the quantum state of photoelectrons ejected from helium and argon in the vicinity of a Fano resonance. In the latter case, we furthermore distill ion-
Low-frequency noise (LFN), or 1/ f -noise, can be used effectively to evaluate device reliability which is a major concern in analog as well as digital circuits. In this work, we present 1/ f -noise characterization of vertical InAs/InGaAs gate-all-around (GAA) MOSFETs with a 70-nm gate length ( LG ) measured at cryogenic temperatures down to 15 K. The measurements at cryogenic temperatures reveal
We analyzed the morphology and the transcriptomic changes of human neural stem progenitor cells (hNSPCs) grown on laminin in adherent culture conditions and subjected to simulated microgravity for different times in a random positioning machine apparatus. Low-cell-density cultures exposed to simulated microgravity for 24 h showed cell aggregate formation and significant modulation of several genes
Last June, the stem cell community came together to celebrate the 20th anniversary of the International Society for Stem Cell Research (ISSCR), one of the leading organizations in the field. The hybrid event mixed a varied program filled with plenary talks, concurrent track sessions, poster presentations, exhibit booths, and plenty of opportunities to enhance stem cell research through bonding bet
Au-seeded semiconductor nanowires have classically been considered to only grow in a layer-by-layer growth mode, where individual layers nucleate and grow one at a time with an incubation step in between. Recent in situ investigations have shown that there are circumstances where binary semiconductor nanowires grow in a multilayer fashion, creating a stack of incomplete layers at the interface bet
Objective: To identify and quantify potential risk factors for osteoarthritis (OA) following traumatic knee injury. Design: Systematic review and meta-analyses that estimated the odds of OA for individual risk factors assessed in more than four studies using random-effects models. Remaining risk factors underwent semiquantitative synthesis. The modified GRADE (Grading of Recommendations Assessment
Background and aims: Previous studies reported divergent results on whether metabolically healthy obesity is associated with increased coronary artery calcium and carotid plaques. We investigated this in a cross-sectional fashion in a large, well-defined, middle-aged population using coronary CT angiography (CCTA) and carotid ultrasound. Methods: In the SCAPIS study (50–65 years, 51% female), CCTA
Background and Aims: There is evidence that housing issues are associated with health outcomes as people age, but little is known in this respect regarding the specific population of people with Parkinson's disease (PD). The objective of this literature review was to identify and analyze the knowledge gap concerning people with PD and housing issues. Methods: Applying established guidelines for sc
Objectives Dietary supplements may ameliorate SARS-CoV-2 infection, although scientific evidence to support such a role is lacking. We investigated whether users of the COVID-19 Symptom Study app who regularly took dietary supplements were less likely to test positive for SARS-CoV-2 infection. Design App-based community survey. Setting 445 850 subscribers of an app that was launched to enable self
The rising prevalence of type 2 diabetes among migrant populations from low- and middle-income countries (LMICs) living in high-income countries (HICs) presents a significant public health challenge. Migrants often experience lifestyle changes, socioeconomic disadvantages and barriers to accessing healthcare, which can increase their risk for type 2 diabetes. This review explores the prevention an
Aims: The objective of this study was to compare the risk of developing type 1 diabetes in individuals with celiac disease, hyperthyroidism and hypothyroidism to that of individuals without those conditions. Materials and Methods: In this retrospective, observational, matched-cohort study based on real-world claims data, individuals with at least one diagnosis of celiac disease, hyperthyroidism (e
Individuals with immigrant background generally perform less well in school than non-immigrants. Performing well in school may decrease the risk of substance use disorder (SUD). We investigated whether higher school performance is associated with a decreased risk of SUD in early adulthood among immigrants and non-immigrants and whether subsequent educational attainment and employment status partly
