The relatively high ranking of psychosocial factors highlights their importance for patients, in addition to factors of biological origin, and indicates that the contextual nature of the lived experience of low back pain may not be covered in standard examinations used in manual medicine.
Despite cultural differences, patients seeking manual care for low back pain in Botswana, Canada and Norway reported similar experiences of disability across ICF domains. The relatively high ranking of psychosocial factors highlights their importance for patients, in addition to factors of biological origin, and indicates that the contextual nature of the lived experience of low back pain may not be covered in standard examinations used in manual medicine.
This study aimed to explore the development of working conditions within and between occupations in the Swedish labor market from 1997 to 2015 and whether any polarization in working conditions concurrently occurred between occupations.

Cross-sectional data from ten waves of the Swedish Work Environment Surveys (1997-2015) were used and an aggregated occupational-level dataset was created using the Swedish Standard Classification of Occupations. To capture the patterns of change in working conditions over time (ie, growth), growth curve modeling was used to identify the starting points for 89 occupations (intercepts) as well as both the shape (functional form) and rate of growth (slope) over time.

The Swedish labor market was stable overall, with some small, mainly positive, changes in job demands and resources. BOS172722 MPS1 inhibitor Different occupations developed in divergent directions, but there was no evidence of polarization.

The findings indicate that macro-level stability can hide highly heterogeneous patterns of change among different occupational groups. This type of analysis, taking context into account, could be valuable for decision makers intending to improve the work environment.

The coronavirus disease 2019 (COVID-19) pandemic led to a near-total cessation of mammography services in the United States in mid-March 2020. It is unclear if screening and diagnostic mammography volumes have recovered to pre-pandemic levels and whether utilization has varied by women's characteristics.

We collected data on 461,083 screening mammograms and 112,207 diagnostic mammograms conducted during January 2019 through July 2020 at 62 radiology facilities in the Breast Cancer Surveillance Consortium. We compared monthly screening and diagnostic mammography volumes before and during the pandemic, stratified by age, race/ethnicity, breast density, and family history of breast cancer.

Screening and diagnostic mammography volumes in April 2020 were 1.1% (95% confidence interval [CI] = 0.5% to 2.4%) and 21.4% (95% CI = 18.7% to 24.4%) of April 2019 pre-pandemic volumes, respectively, but by July 2020 rebounded to 89.7% (95% CI = 79.6% to 101.1%) and 101.6% (95% CI = 93.8% to 110.1%) of July 2019 pre-panmulative deficit in missed mammograms accumulated, which may have important health consequences.Traditional filtered back projection (FBP) reconstruction methods have served the computed tomography (CT) community well for over 40 years. With the increased use of CT during the last decades, efforts to minimise patient exposure, while maintaining sufficient or improved image quality, have led to the development of model-based iterative reconstruction (MBIR) algorithms from several vendors. The usefulness of the advanced modeled iterative reconstruction (ADMIRE) (Siemens Healthineers) MBIR in abdominal CT is reviewed and its noise suppression and/or dose reduction possibilities explored. Quantitative and qualitative methods with phantom and human subjects were used. Assessment of the quality of phantom images will not always correlate positively with those of patient images, particularly at the higher strength of the ADMIRE algorithm. With few exceptions, ADMIRE Strength 3 typically allows for substantial noise reduction compared to FBP and hence to significant (≈30%) patient dose reductions. The size of the dose reductions depends on the diagnostic task.Over the past 25 years, there has been significant progress in increasing the recognition of, resources for, and action on adolescent health, and adolescent sexual and reproductive health (ASRH) in particular. As with numerous other health areas, however, many of the projects that aim to improve ASRH are implemented without well-thought-out plans for evaluation. As a result, the lessons that projects learn as they encounter and address policy and programmatic challenges are often not extracted and placed in the public arena. In such cases, post-project evaluation (PPE) offers the possibility to generate learnings about what works (and does not work), to complement prospective studies of new or follow-on projects. To fill the gap in the literature and guidance on PPE, the World Health Organization developed The project has ended, but we can still learn from it! Practical guidance for conducting post-project evaluations of adolescent sexual and reproductive health projects. This article provides an overview of the guidance by outlining key methodological and contextual challenges in conducting PPE, as well as illustrative solutions for responding to them.
Social dysfunction is adversely associated with individuals' physical and mental quality of life. However, little is known about the status of social dysfunction and its associated factors in patients with heart failure. Our study aimed to reveal the prevalence of social dysfunction, and the associations between fatigue, dyspnoea, anxiety, depression, social connectedness, and social dysfunction in patients with heart failure.

We assessed the social dysfunction, fatigue, dyspnoea, anxiety, depression, and social connectedness using self-report questionnaires among 291 patients (64.13 ± 11.84 years, 53.3% male) with heart failure. Two stepwise forward logistic regression models were employed to identify the factors associated with social dysfunction, and the area under receiver operating characteristic curve was used to calculate the variance of the associated factors accounting for social dysfunction. Of the 291 patients, 76.6% reported social dysfunction. The logistic regression model after adjusting co-variables showed that fatigue [odds ratio (OR) 4.
