The prognostic value of left atrial (LA) strain in patients with heart failure with reduced ejection fraction (HFrEF) has not been fully elucidated. Therefore, this study investigated the prognostic value of LA strain in HFrEF patients in relation to all-cause mortality.
A total of 822 echocardiograms from HFrEF patients admitted to a heart failure clinic were analysed offline. To calculate left atrial reservoir strain (LA RS) and left atrial contractile strain (LA CS), LA two-dimensional speckle tracking was performed in the 4-chamber, 2-chamber and 3-chamber view. The end-point was all-cause mortality. The association between LA strain parameters and outcome was examined using Cox regression.
The median follow-up time was 40 months and follow-up was 100% complete. During follow-up, a total of 137 patients (16.7%) died of all causes. In a final multivariable model adjusted for clinical and echocardiographic parameters including global longitudinal strain, LA RS and LA CS were significantly associated with all-cause death during follow-up (LA RS, HR 0.96, 95% CI 0.92 to 0.99, p=0.014, pr. 1% increase) (LA CS, HR 0.95, 95% CI 0.92 to 0.98, p=0.002, pr. 1% increase).
When added to the final multivariable model, both LA RS and LA CS contributed with incremental prognostic value as determined by C-statistic (LA RS: C-stat difference 0.007, 95% CI 0.000 to 0.020, p=0.050) (LA CS: C-stat difference 0.009, 95% CI 0.000 to 0.023, p=0.030).
In HFrEF patients, LA RS and LA CS were associated with all-cause mortality and contributed incremental prognostic value in addition to established prognostic measures.

Diarrhea outbreaks significantly affect the health and growth of farmed mink, posing economic and welfare challenges. While various pathogens have been linked to mink diarrhea, the causes during the weaning period remain unclear. Sporadic associations of mink coronavirus (MCoV), Campylobacter, and gastrointestinal disease in mink have been suggested. This study investigates the occurrence and levels of MCoV and Campylobacter in fecal samples from Danish farm mink (Neogale vison) and their potential association with post-weaning anorexia diarrhea syndrome (PADS), growth-period diarrhea (GPD), or pre-weaning diarrhea (PWD). The focus of the study is on PADS, studied through two case-control setups where case farms had known problems with PADS and control farms without such problems. Animals were also diagnosed based on necropsy pathological findings. Seventeen MCoV genomes were determined from five Danish farms. This data facilitated the development of an MCoV RT-qPCR and was applied across three study groups. Results showed high prevalence of both MCoV and Campylobacter spp. in all groups. No link was found between MCoV presence or levels and PADS diagnosis on the individual level; however, farm-level analysis revealed that MCoV was 2.35 times more likely (95% CI 1.027; 5.056) on PADS case farms than controls. Mink with PWD exhibited higher MCoV levels compared to GPD cases, suggesting a role at this developmental stage. Phylogenetic analysis revealed diverse and farm-specific MCoV strains, with sequences from healthy controls forming a distinct subclade, hinting at strain-specific pathogenicity. Campylobacter spp. presence was not significantly associated with PADS, but higher levels were observed in mink with PADS versus those without (not tested for PWD). These findings highlight the importance of surveillance and rigorous hygiene practices on mink farms to address risks from MCoV and Campylobacter spp., calling for further research to clarify their roles in PADS and overall mink health.To identify the prevalence and types of missed nursing care in a Danish hospital context from patients' perspectives and to examine associations between missed nursing care, patient demographics, and patient-reported adverse events.
Cross-sectional study.
A total of 284 medical and surgical patients from 21 wards at a Danish university hospital completed the Danish version of the MISSCARE Survey–Patient. Descriptive statistics and analyses of associations between missed nursing care and patient demographics and adverse events were conducted.
Patients reported an overall prevalence of missed nursing care of 15%, with most omissions occurring in the physical care domain (22%), followed by psychosocial care (13%) and timeliness (6%). The most frequently missed activities included oral care, clarity about which nurse was responsible for their care, repositioning in bed, and help with eating. Medication errors were significantly associated with higher missed nursing care scores across all domains, while associations with other adverse events and demographics were inconsistent.
Patients generally perceived a low prevalence of missed nursing care, although notable variations were observed across care domains and specific activities. Incorporating patient perspectives alongside nurse perspectives offers a more complete understanding of missed nursing care.
Continuous assessment of missed nursing care from patients' perspectives could serve as a valuable complement to nurse-reported assessments, helping to identify specific areas for improvement. Targeted interventions addressing activities with higher patient-reported missed nursing care may enhance both care quality and patient outcomes.
STROBE guidelines were followed.
Patients were not involved in the study's design, conduct, or reporting.
This study highlights missed nursing care from patients' perspectives, revealing key care gaps. The findings can inform hospital administrators, nursing leaders, nursing educators, and policymakers in developing strategies to improve care quality and patient satisfaction.
To translate, cross-culturally adapt, validate and psychometrically test the MISSCARE Survey–Patient for assessing patients' perspectives on missed nursing care (MNC) in a Danish hospital setting.
A two-phase cross-cultural adaptation and psychometric validation study.
The study was conducted in two phases. First, the MISSCARE Survey–Patient was cross-culturally adapted to ensure its relevance in a Danish hospital context. This phase involved translation and back-translation, expert committee reviews and cognitive interviews with 18 inpatients to establish content validity. Second, a convenience sample of 284 patients from surgical and medical departments completed the adapted survey. Psychometric properties were evaluated using structural equation modelling to test a second-order formative model.
The cross-cultural adaptation phase led to minor and substantial revisions, including the addition of six new items to enhance content validity. These items addressed aspects of nursing care relevant to patients in the contemporary hospital setting that were not captured by the original survey. Structural equation modelling confirmed the second-order formative model and demonstrated robust psychometric properties.
The MISSCARE Survey–Patient was successfully adapted and validated for use in Danish hospitals, ensuring strong content validity and psychometric robustness.
The Danish version of the survey provides a valuable tool for assessing MNC from patients' perspectives in hospital settings. Its use can help identify specific areas where nursing care falls short, guiding targeted initiatives to enhance care quality and patient safety. By integrating patients' experiences into quality improvement initiatives, the survey supports the development of more person-centred care practices.
The study adhered to the COnsensus-based Standards for the selection of health Measurement INstruments reporting guideline for studies on measurement properties of patient-reported outcome measures.
Patients were not involved in the study's design, conduct, or reporting.
The Danish version of the survey facilitates data collection on patients' perspectives of MNC in contemporary hospital settings, providing valuable insights into care quality. By offering a validated tool to assess MNC from patients' perspectives, the survey helps hospitals identify care gaps, prioritise improvement efforts and enhance person-centred care.
