Associations of serum and tissue TIMP1 with host response and survival in colorectal cancer.

Tissue inhibitor of matrix metalloproteinase 1 (TIMP1) is a multifaceted, cytokine-like bioactive molecule whose levels are elevated in a wide range of inflammatory diseases and are associated with prognosis. Additionally, TIMP1 may play a role in driving systemic inflammation. TIMP1 immunohistochemistry and TIMP1 serum concentrations were analyzed in a cohort of 776 colorectal cancer patients.

Pathological variants in HPV-independent vulvar tumours.

Vulvar cancer is a rare gynaecological disease that can be caused by infection with human papillomavirus (HPV). The mutational frequencies and landscape for HPV-associated and HPV-independent vulvar tumor development are supposedly two distinctly different pathways and more detailed knowledge on target biological mechanisms for individualized future treatments is needed. The study included formalin-fixed paraffin-embedded (FFPE) samples from 32 cancer patients (16 HPV-negative and 16 HPV-associated), treated in Örebro, Sweden from 1988 to 2008.

A CRISPR-Cas9 system protecting E. coli against acquisition of antibiotic resistance genes.

Antimicrobial resistance (AMR) is an increasing problem worldwide, and new treatment options for bacterial infections are direly needed. Engineered probiotics show strong potential in treating or preventing bacterial infections. However, one concern with the use of live bacteria is the risk of the bacteria acquiring genes encoding for AMR or virulence factors through horizontal gene transfer (HGT), and the transformation of the probiotic into a superbug.

The impact of air pollution control measures and the COVID-19 pandemic on photosynthesis in urban trees.

Phytotoxic air pollutants such as atmospheric nitrogen dioxide (NO) are among the major stresses affecting tree photosynthesis in urban areas. We clarified the relationship between NO concentrations and photosynthetic function for three major urban trees, Prunus × yedoensis, Rhododendron pulchrum, and Ginkgo biloba, planted in Kyoto and surrounding cities, combining our published data and new data collected from 2020 to 2023. High NO increased long-term water use efficiency for all species.

Water, sanitation, handwashing, and nutritional interventions can reduce child antibiotic use: evidence from Bangladesh and Kenya.

Antibiotics can trigger antimicrobial resistance and microbiome alterations. Reducing pathogen exposure and undernutrition can reduce infections and antibiotic use. We assess effects of water, sanitation, handwashing (WSH) and nutrition interventions on caregiver-reported antibiotic use in Bangladesh and Kenya, longitudinally measured at three timepoints among birth cohorts (ages 3-28 months) in a cluster-randomized trial.

High-impedance microwave resonators with two-photon nonlinear effects.

Nonlinear effects play a central role in photonics as they form the foundation for most of the device functionalities such as amplification and quantum state preparation and detection. Typically the nonlinear effects are weak and emerge only at high photon numbers with strong drive. Here we present an experimental study of a Josephson junction -based high-impedance resonator.

Influenza A Virus H7 nanobody recognizes a conserved immunodominant epitope on hemagglutinin head and confers heterosubtypic protection.

Influenza remains a persistent global health challenge, largely due to the virus' continuous antigenic drift and occasional shift, which impede the development of a universal vaccine. To address this, the identification of broadly neutralizing antibodies and their epitopes is crucial. Nanobodies, with their unique characteristics and binding capacity, offer a promising avenue to identify such epitopes.

Prednisolone versus antihistamine for allergic rhinitis: No significant difference found in randomized trial.

Background: Seasonal allergic rhinitis (AR) impacts public health by affecting work productivity and quality of life. The Swedish tree pollen season starts in February with alder and hazel pollination, followed by birch and ends with oak in May. Systemic corticosteroids are often prescribed when topical treatments fail, despite limited evidence supporting their efficacy.

First out-of-bed mobilisation in adults with severe acquired brain injury in Scandinavian neurointensive care units: A survey of current clinical practice (FOOBScan).

Background: The harm-benefit balance for early out-of-bed mobilisation of patients with severe acquired brain injury (ABI) in neurointensive care units (neuro-ICUs) is unclear, and there are no clinical guidelines. This study aimed to survey the current clinical practice and perceptions among clinicians involved in first out-of-bed mobilisation in Scandinavian neuro-ICUs.

Methods: This was a cross-sectional, anonymous, web-based survey; the reporting follows the recommended CROSS checklist.

Deep learning model to identify and validate hypotension endotypes in surgical and critically ill patients.

Background: Hypotension is associated with organ injury and death in surgical and critically ill patients. In clinical practice, treating hypotension remains challenging because it can be caused by various underlying haemodynamic alterations. We aimed to identify and independently validate endotypes of hypotension in big datasets of surgical and critically ill patients using unsupervised deep learning.

Sex hormone-dependent host-microbiome interactions and cardiovascular risk (XCVD): design of a longitudinal multi-omics cohort study.

Introduction: Cardiovascular diseases (CVDs) present differently in women and men, influenced by host-microbiome interactions. The roles of sex hormones in CVD outcomes and gut microbiome in modifying these effects are poorly understood. The XCVD study examines gut microbiome mediation of sex hormone effects on CVD risk markers by observing transgender participants undergoing gender-affirming hormone therapy (GAHT), with findings expected to extrapolate to cisgender populations.

Content and outcome of non-pharmacological rehabilitation in hospital, or community-based care, for women with traumatic brain injury: a scoping review protocol.

Introduction: Traumatic brain injury (TBI) is a global health issue and a leading cause of long-term disabilities and mortality worldwide. There is growing evidence that TBI rehabilitation should be differentiated and individualised according to gender to provide more effective healthcare and rehabilitation. However, there is a lack of reviews focusing on the rehabilitation for women with TBI and there is a need to summarise existing knowledge to guide and individualise their rehabilitation.

Precuneus activity during retrieval is positively associated with amyloid burden in cognitively normal older carriers.

The precuneus is a site of early amyloid-beta (Aβ) accumulation. Previous cross-sectional studies reported increased precuneus fMRI activity in older adults with mild cognitive deficits or elevated Aβ. However, longitudinal studies in early Alzheimer's disease (AD) are lacking and the relationship to the Apolipoprotein-E () genotype is unclear.

Characteristics and impact of pain from root-filled teeth. A practice-based cross-sectional study comparing painful teeth with and without signs of inflammatory dental disease.

To compare pain characteristics, impact of pain and characteristics of patients with painful root-filled teeth with and without signs of inflammatory dental disease. This cross-sectional study was performed in the Public Dental Health services, Region Örebro County, Sweden. Adult patients with ≥1 root-filled tooth identified at their regular check-up were included and assigned to one of two groups; those with ≥1 sign of inflammatory dental disease (DD+) and those without any such sign (DD-).

Trajectory of Depressive Symptoms in a Longitudinal Stroke Cohort.

Objectives: Knowledge of the trajectory of post-stroke depression is important to identify high-risk patients, develop precise management programs and enhance prognosis. We aimed to characterise the course of depressive symptoms within the first year post-stroke and to evaluate associations with time.

Materials And Methods: Depressive symptoms were measured using the Montgomery-Åsberg Depression Rating Scale (MADRS) within the first week, and at 3- and 12-months post-stroke.

Common infections in children aged 6 months to 7 years after high prenatal exposure to perfluoroalkyl substances from contaminated drinking water in Ronneby, Sweden.

Background: Perfluorinated alkyl substances (PFAS) are suggested to impair immune function in children. Previous studies investigating associations between prenatal PFAS exposure and common infections were performed in background-exposed populations whilst studies from high-exposed populations are lacking.

Objectives: To investigate the association between prenatal PFAS exposure from contaminated drinking water and common infections in children aged 6 months to 7 years in Ronneby, Sweden.

Association of Residential Greenness and Sleep Duration in Adults: A Prospective Cohort Study in China.

Background: Exposure to residential greenness has been linked with improved sleep duration; however, longitudinal evidence is limited, and the potential mediating effect of ambient fine particulate matter (PM) has yet to be assessed.

Methods: We obtained data for 19,567 participants across seven counties in a prospective cohort in Ningbo, China. Greenness was estimated using Normalized Difference Vegetation Index (NDVI) within 250-m, 500-m and 1000-m buffer zones, while yearly average PM concentrations were measured using validated land-use regression models, both based on individual residential addresses.

Consequences of weaning and separation for feed intake and milking characteristics of dairy cows in a cow-calf contact system.

In cow-calf contact (CCC) systems breaking the maternal bond may induce stress for the cow, thereby affecting feed intake, milk yield, milk flow rate, and milk electrical conductivity. This study aimed to determine the consequences of weaning and separation strategies in CCC systems for feed intake and milking characteristics of the cow. In 2 experiments, Swedish Holstein and Swedish Red cows either had (experiment 1) whole-day CCC (CCC1, n = 12) for 8.

Vaccination against measles-mumps-rubella and rates of non-targeted infectious disease hospitalisations: Nationwide register-based cohort studies in Denmark, Finland, Norway, and Sweden.

Objectives: To investigate if receipt of measles-mumps-rubella (MMR) vaccine following the third dose of diphtheria-tetanus-acellular pertussis (DTaP3) is associated with reduced rates of non-targeted infectious disease hospitalisations.

Methods: Register based cohort study following 1,397,027 children born in Denmark, Finland, Norway, and Sweden until 2 years of age. Rates of infectious disease hospitalisations with minimum one overnight stay according to time-varying vaccination status were compared using Cox proportional hazards regression analysis with age as the underlying timescale and including multiple covariates.
