Loss of collagen content is localized near cartilage lesions on the day of injurious loading and intensified on day 12.

Joint injury can lead to articular cartilage damage, excessive inflammation, and post-traumatic osteoarthritis (PTOA). Collagen is an essential component for cartilage function, yet current literature has limited understanding of how biochemical and biomechanical factors contribute to collagen loss in injured cartilage. Our aim was to investigate spatially dependent changes in collagen content and collagen integrity of injured cartilage, with an explant model of early-stage PTOA. We subjected calf knee cartilage explants to combinations of injurious loading (INJ), interleukin-1α-challenge (IL) and physiological cyclic loading (CL). Using Fourier transform infrared microspectroscopy, collagen content (Amide I band) and collagen integrity (Amide II/1338 cm-1 ratio) were estimated on days 0 and 12 post-injury. We found that INJ led to lower collagen content near lesions compared to intact regions on day 0 (p < 0.001). On day 12, near-lesion collagen content was lower compared to day 0 (p < 0.05). Additionally, on day 12, INJ, IL, and INJ + IL groups exhibited lower collagen content along most of tissue depth compared to free-swelling control group (p < 0.05). CL groups showed higher collagen content along most of tissue depth compared to corresponding groups without CL (p < 0.05). Immunohistochemical analysis revealed higher MMP-1 and MMP-3 staining intensities localized within cell lacunae in INJ group compared to CTRL group on day 0. Our results suggest that INJ causes rapid loss of collagen content near lesions, which is intensified on day 12. Additionally, CL could mitigate the loss of collagen content at intact regions after 12 days.

Association between air temperature and self-perceived health status in Southern Germany: Results from KORA FIT study.

BACKGROUND: Short-term exposure to low and high air temperatures can cause serious harmful effects on human health. Existing literature has mostly focused on associations of ambient air temperature with mortality and the need for health care in population-level studies. Studies that have considered self-perceived health status as an outcome when examining the effects of air temperature on health are scarce. In this study, we explored the short-term association of daily mean air temperature with various measures of self-perceived health status. METHODS: This cross-sectional analysis is based on the Cooperative Health Research in the Region of Augsburg (KORA) FIT study conducted in 2018/2019 and included participants from the Augsburg region of Southern Germany. Health-related quality of life (HRQOL) was evaluated by using the 5-level EuroQol Five Dimension (EQ-5D-5L) questionnaire, including the EuroQol visual analog scale (EQ-VAS). Self-rated health (SRH) and comparative self-rated health (CSRH) were each assessed using a single question. Daily mean air temperature data was estimated using a spatiotemporal model and assigned to participants' home addresses at a resolution of 1 × 1 km. Regression models with a Distributed Lag Non-linear Modeling (DLNM) approach were used to investigate the associations between daily mean air temperature and self-perceived health measures. RESULTS: We found no association of heat or cold with the HRQOL, SRH or CSRH. Nevertheless, there was a significant protective association of low air temperature with the EQ-5D-5L dimension "usual activities." CONCLUSION: There was no evidence of daily mean air temperature adversely affecting participants' self-perceived health status.

Patient safety incident reporting software: A cross-sectional survey of nurses and other users' perspectives.

AIM: To investigate nurses' and other users' perceptions and knowledge regarding patient safety incident reporting software and incident reporting. DESIGN: A cross-sectional online survey. METHODS: The survey, 'The Users' Perceptions of Patient Safety Incident Reporting Software', was developed and used for data collection January-February 2024. We aimed to invite all potential users of reporting software in two wellbeing service counties in Finland to participate in the survey. Potential users (reporters/handlers/others) were nurses, other health professionals and employees. Satisfaction was classified as dissatisfied, neutral, or satisfied. The association between overall satisfaction and demographics was tested using cross-tabulation and a Chi-square test. RESULTS: The completion rate was 54% (n = 755). Some respondents (n = 25) had never used reporting software, most often due to no perceived need to report, although their average work experience was 15 years. Of other respondents (n = 730), mostly nurses (n = 432), under half agreed that the software was quick to use and easy to navigate. The biggest dissatisfaction was with the report processing features. Over a fifth did not trust that reporting was anonymous. Training and frequency of using the software were associated with overall satisfaction. CONCLUSION: Reporting software has not reached its full potential and needs development. Report handling is essential for shared learning; however, the processing features require the most improvements. Users' perceptions must be considered when developing reporting software and processes. IMPACT: Incident reporting software usability is central to reporting, but nurses' and other users' perceptions of software are poorly understood. This survey shows weaknesses in reporting software and emphasizes the importance of training. The survey can contribute to paying more attention to organizing training, getting users to participate in software development, and deepening knowledge of issues in reporting software. Making the needed improvements could improve patient safety. REPORTING METHOD: The STROBE Checklist (Supplement-S1). PATIENT OR PUBLIC CONTRIBUTION: No Patient or Public Contribution.

Long-term exposures to low concentrations of source-specific air pollution, road-traffic noise, and systemic inflammation and cardiovascular disease biomarkers.

OBJECTIVES: Air pollution and traffic noise are detrimental to cardiovascular health. However, the effects of different sources of these exposures on cardiovascular biomarkers remain unclear. We explored the associations of long-term exposure to source-specific air pollution (vehicular exhausts and residential woodsmoke) at low concentrations and road-traffic noise with systemic inflammation and cardiovascular disease biomarkers. MATERIAL AND METHODS: Modeled outdoor exposure to fine particulate matter (aerodynamic diameter ≤2.5 µm; PM2.5) from vehicular exhausts and residential woodsmoke, nitrogen dioxide (NO2) from road traffic, and road-traffic noise were linked to the home addresses of the participants (Finnish residents aged 25-74) in the FINRISK study 1997-2012. The participants were located in the cities of Helsinki, Vantaa, and the region of Turku, Finland. The outcomes were high-sensitivity C-reactive protein (CRP), a biomarker for systemic inflammation, and cardiovascular disease biomarkers N-terminal pro-B-type natriuretic peptide (NT-proBNP) and troponin I. We performed cross-sectional analyses with linear and additive models and adjusted for potential confounders. RESULTS: We found no association between PM2.5 from vehicular exhausts (% CRP difference for 1 µg/m3 increase in PM2.5: -0.9, 95% confidence interval, CI: -7.2, 5.8), or from residential woodsmoke (% difference: -8.1, 95% CI: -21.7, 7.9) and CRP (N = 4147). Road-traffic noise >70 dB tended to be positively associated with CRP (% CRP difference versus noise reference category of ≤45 dB: 18.3, 95% CI: -0.5, 40.6), but the association lacked significance and robustness (N = 7142). Otherwise, we found no association between road-traffic noise and CRP, nor between NO2 from road traffic and NT-proBNP (N = 1907) or troponin I (N = 1951). CONCLUSION: Long-term exposures to source-specific, fairly low-level air pollution from vehicular exhausts and residential woodsmoke, or road-traffic noise were not associated with systemic inflammation and cardiovascular disease biomarkers in this urban area.

Impact of three decades of warming, increased nutrient availability, and increased cloudiness on the fluxes of greenhouse gases and biogenic volatile organic compounds in a subarctic tundra heath.

Climate change is exposing subarctic ecosystems to higher temperatures, increased nutrient availability, and increasing cloud cover. In this study, we assessed how these factors affect the fluxes of greenhouse gases (GHGs) (i.e., methane (CH4), nitrous oxide (N2O), and carbon dioxide (CO2)), and biogenic volatile organic compounds (BVOCs) in a subarctic mesic heath subjected to 34 years of climate change related manipulations of temperature, nutrient availability, and light. GHGs were sampled from static chambers and gases analyzed with gas chromatograph. BVOCs were measured using the push-pull method and gases analyzed with chromatography-mass spectrometry. The soil temperature and moisture content in the warmed and shaded plots did not differ significantly from that in the controls during GHG and BVOC measurements. Also, the enclosure temperatures during BVOC measurements in the warmed and shaded plots did not differ significantly from temperatures in the controls. Hence, this allowed for assessment of long-term effects of the climate treatment manipulations without interference of temperature and moisture differences at the time of measurements. Warming enhanced CH4 uptake and the emissions of CO2, N2O, and isoprene. Increased nutrient availability increased the emissions of CO2 and N2O but caused no significant changes in the fluxes of CH4 and BVOCs. Shading (simulating increased cloudiness) enhanced CH4 uptake but caused no significant changes in the fluxes of other gases compared to the controls. The results show that climate warming and increased cloudiness will enhance CH4 sink strength of subarctic mesic heath ecosystems, providing negative climate feedback, while climate warming and enhanced nutrient availability will provide positive climate feedback through increased emissions of CO2 and N2O. Climate warming will also indirectly, through vegetation changes, increase the amount of carbon lost as isoprene from subarctic ecosystems.

Longitudinal associations of an exposome score with serum metabolites from childhood to adolescence.

Environmental and lifestyle factors, including air pollution, impaired diet, and low physical activity, have been associated with cardiometabolic risk factors in childhood and adolescence. However, environmental and lifestyle exposures do not exert their physiological effects in isolation. This study investigated associations between an exposome score to measure the impact of multiple exposures, including diet, physical activity, sleep duration, air pollution, and socioeconomic status, and serum metabolites measured using LC-MS and NMR, compared to the individual components of the score. A general population of 504 children aged 6-9 years at baseline was followed up for eight years. Data were analysed with linear mixed-effects models using the R software. The exposome score was associated with 31 metabolites, of which 12 metabolites were not associated with any individual exposure category. These findings highlight the value of a composite score to predict metabolic changes associated with multiple environmental and lifestyle exposures since childhood.

Eight-year diet and physical activity intervention affects serum metabolites during childhood and adolescence: A nonrandomized controlled trial.

Long-term lifestyle interventions in childhood and adolescence can significantly improve cardiometabolic health, but the underlying molecular mechanisms remain poorly understood. To address this knowledge gap, we conducted an 8-year diet and physical activity intervention in a general population of children. The research revealed that the intervention influenced 80 serum metabolites over two years, with 17 metabolites continuing to be affected after eight years. The intervention primarily impacted fatty amides, including palmitic amide, linoleamide, oleamide, and others, as well as unsaturated fatty acids, acylcarnitines, phospholipids, sterols, gut microbiota-derived metabolites, amino acids, and purine metabolites. Particularly noteworthy were the pronounced changes in serum fatty amides. These serum metabolite alterations could represent molecular mechanisms responsible for the observed benefits of long-term lifestyle interventions on cardiometabolic and overall health since childhood. Understanding these metabolic changes may provide valuable insights into the prevention of cardiometabolic and other non-communicable diseases since childhood.

Prenatal Urban Environment and Blood Pressure Trajectories From Childhood to Early Adulthood.

Background: Prenatal urban environmental exposures have been associated with blood pressure in children. The dynamic of these associations across childhood and later ages is unknown. Objectives: The purpose of this study was to assess associations of prenatal urban environmental exposures with blood pressure trajectories from childhood to early adulthood. Methods: Repeated measures of systolic blood pressure (SBP) and diastolic blood pressure (DBP) were collected in up to 7,454 participants from a UK birth cohort. Prenatal urban exposures (n = 43) covered measures of noise, air pollution, built environment, natural spaces, traffic, meteorology, and food environment. An exposome-wide association study approach was used. Linear spline mixed-effects models were used to model associations of each exposure with trajectories of blood pressure. Replication was sought in 4 independent European cohorts (up to 9,261). Results: In discovery analyses, higher humidity was associated with a faster increase (mean yearly change in SBP for an interquartile range increase in humidity: 0.29 mm Hg/y, 95% CI: 0.20-0.39) and higher temperature with a slower increase (mean yearly change in SBP per interquartile range increase in temperature: -0.17 mm Hg/y, 95% CI: -0.28 to -0.07) in SBP in childhood. Higher levels of humidity and air pollution were associated with faster increase in DBP in childhood and slower increase in adolescence. There was little evidence of an association of other exposures with change in SBP or DBP. Results for humidity and temperature, but not for air pollution, were replicated in other cohorts. Conclusions: Replicated findings suggest that higher prenatal humidity and temperature could modulate blood pressure changes across childhood.

Impact of second victim distress on healthcare professionals' intent to leave, absenteeism and resilience: A mediation model of organizational support.

AIMS: To examine the relationship between the second victim distress and outcome variables, specifically: 'turnover intentions, absenteeism and resilience'. Furthermore, this study also assessed how organizational support mediates the relationship between second victim distress and outcome variables. DESIGN: Cross-sectional survey. METHODS: A cross-sectional survey study using regression and mediation analysis with bootstrapping was conducted among (n = 149) healthcare professionals in two university hospitals in Finland from September 2022 to April 2023 during different time periods. The Finnish version of the revised Second Victim Experience and Support Tool (FI-SVEST-R) was used to assess second victim distress, level of organizational support and related outcomes. RESULTS: Psychological distress was the most frequently experienced form of reported second victim distress, and institutional support was the lowest perceived form of support by healthcare professionals. The study found second victim distress to have a significant association with work-related outcomes: turnover intention and absenteeism. However, no significant relationship was found with resilience. Mediation models with organizational support revealed a partially mediated relationship between second victim distress and work-related outcomes. CONCLUSIONS: The findings from this study indicate that second victim experiences if not adequately addressed can lead to negative work-related outcomes such as increased job turnover and absenteeism. Such outcomes not only affect healthcare professionals but can also have a cascading effect on the quality of care. However, the mediating effect of organizational support suggests that if comprehensive support is provided, it is possible to mitigate the negative impact of the second victim phenomenon. IMPACT: Raising awareness regarding the second victim phenomenon, promoting a culture of safety and shifting the paradigm from a blame to just culture helps in identifying the system flaws thus improving both patient and provider safety. REPORTING METHOD: The study adheres to the STROBE reporting guidelines. PATIENT OR PUBLIC CONTRIBUTION: No patient or public contribution.

Dataset of vehicle chase measurements in real-world subfreezing winter conditions.

This dataset comprises thorough measurements of light-duty vehicles emissions conducted in Siilinjärvi and Kuopio, Finland, during February 2021, using a mobile laboratory. The measurements focused on subfreezing conditions to capture emissions nuances during cold weather. Measurements were carried out on minimally trafficked roads to diminish external disturbances. The dataset includes a large number of variables from gas and particle emissions. Gaseous emissions of CO, CO2, and NOx were measured. Measured variables of particle emissions were number concentration (CPC), size distribution (ELPI+), black carbon concentration (AE33), and chemical composition (SP-AMS). A total of six light-duty vehicles were investigated, featuring three diesel and three gasoline engines. The measurements incorporated three distinct drive scenarios: subfreezing-cold start, preheated-cold start (utilizing either electrical or fuel-operated auxiliary heaters), and hot start (where a vehicle engine has reached the optimal temperature through prior driving). Each drive type was replicated twice, resulting in six driven rounds per vehicle and 36 rounds in total. Additionally, daily background measurements were conducted by following the same route without chasing a specific vehicle. Meteorological conditions during the measurements were representative of winter in Finland, with outside temperatures ranging from -9 °C to -28 °C. The effect of weather conditions on the measurements were minimal. Only a minor effect was due to the occasional snowfall, especially on the last day when the road surface was snowy, and the car being chased lifted the snow from the road surface. We didn't recognize other factors, such as high wind speeds or major road dust emissions, that could have affected the measurement results. This dataset serves as a valuable resource for comparing emissions under diverse environmental conditions, particularly in real-life winter settings where data are scarce. Furthermore, it provides an opportunity for meta-analysis of emission factors from various passenger vehicle types. The dataset's richness and specificity make it a valuable contribution to the understanding of winter-time vehicular emissions.

The role of social media in the professional sphere of Finnish registered dietitians.

BACKGROUND: With the widespread use of social media, understanding how healthcare professionals, such as dietitians, utilise these platforms for their work has gained interest. The aim of the current study was to describe how Finnish registered dietitians utilise various social media channels for professional purposes. The study also investigated the perceived social media skills of dietitians. METHODS: A cross-sectional study was conducted using an online survey administered between December 2022 and February 2023. The participants were 107 Finnish registered dietitians who held a master's degree suitable for the profession. The Fisher's exact test was employed for categorical variables, whereas the Kruskal-Wallis test was used for ordinal variables with multiple groups. RESULTS: Out of the 107 participants, 62 (58%) reported using social media for professional purposes. The primary purposes across various social media channels were interaction with colleagues (80%) on Facebook, networking with professionals from other fields (86%) on LinkedIn and general monitoring of the field on Instagram (91%), Twitter (77%) and YouTube (58%). Dietitians' perceived social media skills were found to have a statistically significant relationship with age (p < 0.05) for all channels, except Twitter. CONCLUSIONS: The findings suggest that Finnish dietitians predominantly utilise social media for passive monitoring of the field, rather than actively sharing content with the public. Professional communication tends to take place within their own professional groups. Incorporating social media use into the official job description could serve as an encouraging factor to enhance the professional utilisation of social media among dietitians.

Organizational characteristics of nursing practice environments related to registered nurses' professional autonomy and job satisfaction in two Finnish Magnet-aspiring hospitals: structural equation modeling study.

BACKGROUND: Nurses are leaving their profession because of poor personal job satisfaction, heavy workload, and unfavorable work environments with low professional autonomy. Professional autonomy involves the possibility to influence one's work and have a sense of control - the ability to contribute to a workplace culture and influence how decisions are made. This study explores registered nurses' perceptions of the nursing practice environment, using the Nursing Work Index-Revised (NWI-R), and its relationships with professional autonomy and job satisfaction. METHODS: A cross-sectional study along with instrument re-validation was conducted using a web-based survey for nurses in two Magnet-aspiring hospitals in Finland in September 2021 (n = 586). Structural equation modeling was used to find out the relationships of the NWI-R components with professional autonomy and job satisfaction. RESULTS: Principal component analysis and confirmatory factor analysis supported seven components with 34 items. Collegial nurse-doctor relationships, organization's quality standards, and nursing involvement and expertise sharing (means of 3.23, 2.96, and 2.66, respectively) demonstrated a favorable nursing practice environment; professional nursing standards, nurse management and leadership, staffing and resource adequacy, and professional advancement (means of 2.38, 2.18, 2.15, and 2.13, respectively) demonstrated an unfavorable nursing practice environment. The presented model (RMSEA 0.068, CFI 0.987, TLI 0.946) indicated that nursing involvement and expertise sharing, organization's quality standards, nurse management and leadership, and collegial nurse-doctor relationships were related to professional autonomy. Nurse management and leadership, staffing and resource adequacy, and organization's quality standards were related to job satisfaction. Moreover, professional autonomy was related to job satisfaction. CONCLUSION: Nurses' professional autonomy is important due to its relationship with job satisfaction. When factors that increase professional autonomy are taken into account and attention is paid to the promotion of autonomy, it is possible to improve nurses' job satisfaction. These issues cannot be solved at the unit level; investment is needed at the organizational and political levels. The results introduce nurses, managers, researchers, and stakeholders to improvements in the nursing practice environment toward an organizational culture where nurses may utilize their professional autonomy to its full potential.

Care quality and satisfaction at the cancer hospital - a questionnaire study of older patients with cancer and their family members.

BACKGROUND: The unique life situations of older patients with cancer and their family members requires that health care professionals take a holistic approach to achieve quality care. The aim of this study was to assess the perceptions of older patients with cancer and family members about the quality of care received and evaluate differences between their perceptions. A further aim was to examine which factors explain patients' and family members' levels of satisfaction with the care received. METHODS: The study was descriptive and cross-sectional in design. Data were collected from patients (n = 81) and their family members (n = 65) on four wards in a cancer hospital, using the Revised Humane Caring Scale (RHCS). Data were analysed using descriptive statistics, crosstabulation, Wilcoxon signed rank test, and multivariable Analysis of Covariance (ANCOVA). RESULTS: Family members had more negative perceptions of the quality of care than patients did. Dissatisfaction was related to professional practice (p < 0.001), interaction between patient and health care professionals (p < 0.001), cognition of physical needs (p = 0.024), and human resources (p < 0.001). Satisfaction with overall care was significantly lower among those patients and family members who perceived that they had not been involved in setting clear goals for the patient's care with staff (p = 0.002). CONCLUSIONS: It is important that older patients with cancer and family members receive friendly, respectful, individual care based on their needs and hopes, and that they can rely on professionals. Health care professionals need more resources and education about caring for older cancer patients to provide quality care.

Association between active commuting and low-grade inflammation: a population-based cross-sectional study.

BACKGROUND: Prior studies suggest that physical activity lowers circulating C-reactive protein (CRP) levels. However, little is known about the association between regular active commuting, i.e. walking or cycling to work, and CRP concentrations. This study examines whether active commuting is associated with lower CRP. METHODS: We conducted a cross-sectional study using population-based FINRISK data from 1997, 2002, 2007 and 2012. Participants were working adults living in Finland (n = 6208; mean age = 44 years; 53.6% women). We used linear and additive models adjusted for potential confounders to analyze whether daily active commuting, defined as the time spent walking or cycling to work, was associated with lower high-sensitivity (hs-) CRP serum concentrations compared with passive commuting. RESULTS: We observed that daily active commuting for 45 min or more (vs. none) was associated with lower hs-CRP [% mean difference in the main model: -16.8%; 95% confidence interval (CI) -25.6% to -7.0%), and results were robust to adjustment for leisure-time and occupational physical activity, as well as diet. Similarly, active commuting for 15-29 min daily was associated with lower hs-CRP in the main model (-7.4; 95% CI -14.1 to -0.2), but the association attenuated to null after further adjustments. In subgroup analyses, associations were only observed for women. CONCLUSIONS: Active commuting for at least 45 min a day was associated with lower levels of low-grade inflammation. Promoting active modes of transport may lead not only to reduced emissions from motorized traffic but also to population-level health benefits.

Associations of low levels of air pollution with cardiometabolic outcomes and the role of diet quality in individuals with obesity.

BACKGROUND: Exposure to air pollution is associated with adverse cardiometabolic health effects and increased mortality, even at low concentrations. Some of the biological mechanisms through which air pollution can affect cardiometabolic health overlap with health outcomes associated with diet quality and changes in diet. OBJECTIVE: The objective of this study is to investigate associations of air pollutants at average concentrations below the World Health Organization, 2021 air quality guidelines with cardiometabolic outcomes. Furthermore, potential interaction between air pollutants and diet quality will be assessed. METHODS: 82 individuals with obesity participated in a combined weight loss and weight loss maintenance study for a total of 33 weeks. A secondary analysis was conducted incorporating air pollution measurements. Data were analysed with linear mixed-effects models. RESULTS: A total of 17 significant associations were observed for single pollutants with 10 cardiometabolic outcomes, predominantly related to blood lipids, hormones, and glucose regulation. Diet quality, as measured by the Baltic Sea Diet score, did not appear to mediate the association of air pollution with cardiometabolic outcomes, however, diet quality was observed to significantly modify the association of PM2.5 with total cholesterol, and the associations of NO and O3 with ghrelin. DISCUSSION: These findings suggest that exposure to ambient air pollutants, especially particulate matter, at levels below World Health Organization, 2021 air quality guidelines, were associated with changes in cardiometabolic risk factors. Diet may be a personal-level approach for individuals to modify the impact of exposure to air pollution on cardiometabolic health.

Refractive index of human articular cartilage varies with tissue structure and composition.

Optical properties of biological tissues, such as refractive index, are fundamental properties, intrinsically linked to a tissue's composition and structure. This study aims to investigate the variation of refractive index (RI) of human articular cartilage along the tissue depth (via collagen fibril orientation and optical density) and integrity (based on Mankin and Osteoarthritis Research Society International (OARSI) scores). The results show the relationship between RI and PG content (p=0.042), collagen orientation (p=0.037), and OARSI score (p=0.072). When taken into account, the outcome of this study suggests that the RI of healthy cartilage differs from that of pathological cartilage (p=0.072). This could potentially provide knowledge on how progressive tissue degeneration, such as osteoarthritis, affects changes in cartilage RI, which can, in turn, be used as a potential optical biomarker of tissue pathology.

Changes in liver metabolic pathways demonstrate efficacy of the combined dietary and microbial therapeutic intervention in MASLD mouse model.

OBJECTIVE: Metabolic dysfunction-associated steatotic liver disease (MASLD), formerly known as non-alcoholic fatty liver disease (NAFLD), is the most prevalent liver disease globally, yet no therapies are approved. The effects of Escherichia coli Nissle 1917 expressing aldafermin, an engineered analog of the intestinal hormone FGF19, in combination with dietary change were investigated as a potential treatment for MASLD. METHODS: MASLD was induced in C57BL/6J male mice by American lifestyle-induced obesity syndrome diet and then switched to a standard chow diet for seven weeks. In addition to the dietary change, the intervention group received genetically engineered E. coli Nissle expressing aldafermin, while control groups received either E. coli Nissle vehicle or no treatment. MASLD-related plasma biomarkers were measured using an automated clinical chemistry analyzer. The liver steatosis was assessed by histology and bioimaging analysis using Fiji (ImageJ) software. The effects of the intervention in the liver were also evaluated by RNA sequencing and liquid-chromatography-based non-targeted metabolomics analysis. Pathway enrichment studies were conducted by integrating the differentially expressed genes from the transcriptomics findings with the metabolites from the metabolomics results using Ingenuity pathway analysis. RESULTS: After the intervention, E. coli Nissle expressing aldafermin along with dietary changes reduced body weight, liver steatosis, plasma aspartate aminotransferase, and plasma cholesterol levels compared to the two control groups. The integration of transcriptomics with non-targeted metabolomics analysis revealed the downregulation of amino acid metabolism and related receptor signaling pathways potentially implicated in the reduction of hepatic steatosis and insulin resistance. Moreover, the downregulation of pathways linked to lipid metabolism and changes in amino acid-related pathways suggested an overall reduction of oxidative stress in the liver. CONCLUSIONS: These data support the potential for using engineered microbial therapeutics in combination with dietary changes for managing MASLD.

Finnish Version of the Specialist Outcomes and Barriers Analysis Scale: Evaluation of Psychometric Properties.

PURPOSE: To evaluate the psychometric properties of the Finnish version of the Specialist Outcomes and Barriers Analysis Scale. DESIGN: This was a cross-sectional survey study. METHODS: Cultural adaptation of the translation and content validity of the translated instrument were assessed by expert panelists (n = 5) using the content validity index. The construct validity was assessed with principal component analysis using the survey data of Finnish registered nurses (n = 60). Scale reliability was assessed with Cronbach's α values. All study phases were conducted in 2021. RESULTS: The items (n = 59) of the scale were critically evaluated by the experts. The full-scale content validity was revealed as excellent (0.92). In terms of construct validity, the scale was analyzed separately for outcomes and barriers. The outcomes section revealed a 5-component structure with an overall Cronbach's α coefficient of .96, and the barriers section, a 2-component structure with an overall Cronbach's α coefficient of .82, indicating adequate reliability of the scale. CONCLUSION: The Finnish version of the scale showed excellent content and construct validity. The Cronbach's α values represented adequate reliability of the Specialist Outcomes and Barriers Analysis scale when measuring nurses' perceived practice outcomes and barriers in the Finnish context.

Measuring health professionals' perceptions of communication contributing to medication incidents in hospitals - scale development and primary results of weekly perceived communication challenges.

BACKGROUND: Communication challenges are one of the main contributors for medication incidents in hospitals, but health professionals' perceptions about variety of the contributing communication factors and the factors' occurrence frequencies are studied little. This cross-sectional descriptive study aimed to (1) operationalize a literature-based framework into a scale for measuring health professionals' perceptions of communication factors, which contribute to medication incidents either directly or indirectly in hospitals, (2) to measure the construct validity and internal consistency of the scale and (3) to describe the primary results of the measured weekly perceived communication challenges. METHODS: The structured online questionnaire with 82 communication related items was developed based on a framework in literature. A content validity index of expert panelists' answers was used for item reduction. Data was collected between November 1st, 2019, and January 31st, 2020, by convenience sampling. The study sample (n = 303) included multiple health professional groups in diverse specialties, unit types and organizational levels in two specialized university hospital districts in Finland. Exploratory factor analysis with Maximum Likelihood method and Oblique rotation produced a six factors scale consisting of 57 items and having acceptable construct validity and internal consistency. RESULTS: The six communication factors contributing to medication incidents concerned (1) medication prescriptions, (2) guidelines and reporting, (3) patient and family, (4) guideline implementation,5) competencies and responsibilities, and 6) attitude and atmosphere. The most frequently perceived communication challenges belonged to the Medication prescription related factor. Detailed item frequencies suggested that the most usual weekly challenges were: (1) lack or unclarity of communication about medication prescriptions, (2) missing the prescriptions which were written outside of the regular physician-ward-rounds and (3) digital software restricting information transfer. CONCLUSIONS: The scale can be used for determining the most frequent detailed communication challenges. Confirmatory factor analysis of the scale is needed with a new sample for the scale validation. The weekly perceived communication challenges suggest that interventions are needed to standardize prescribing documentation and to strengthen communication about prescriptions given outside of regular ward-rounds.

Are active school transport and leisure-time physical activity associated with performance and wellbeing at secondary school? A population-based study.

BACKGROUND: Physically active pupils may be better and more resilient learners. However, it is unclear whether walking or cycling to school yields similar educational and school-related mental health benefits as leisure-time physical activity. We examined the associations of active school transport and leisure-time moderate-to-vigorous physical activity with perceived academic performance, competency in academic skills, school burnout and school enjoyment. METHODS: We included 34 103 Finnish adolescents (mean age 15.4 years; 53% girls) from the 2015 School Health Promotion study cohort. For the analyses, we used logistic regression, adjusting for major sociodemographic, environmental, lifestyle and physical activity covariates. RESULTS: Active school transport was positively associated with educational outcomes and school enjoyment, but not with school burnout. For example, compared with non-active transport, 10-30 min of daily active school transport was linked to 30% [odds ratio (OR) 1.30, 95% confidence interval (CI) 1.21-1.40] and 17% (OR 1.17, 95% CI 1.08-1.27) higher odds of high perceived academic performance and high reading competency, respectively. Leisure-time physical activity was robustly associated with all outcomes. For example, compared with the inactive, the most physically active adolescents had 86% higher odds of high perceived academic performance (OR 1.86, 95% CI 1.66-2.08), 57% higher odds of high competency in mathematics (OR 1.57, 95% CI 1.39-1.77) and 40% lower odds of school burnout (OR 0.60, 95% CI 0.52-0.69). CONCLUSIONS: Compared with active school transport, leisure-time physical activity was more strongly associated with educational and school-related mental health outcomes. Nevertheless, walking or cycling to school might lead to improvements in classroom performance and school enjoyment.
