Comparison of non-invasive and fluorescein tear film break-up time in a 65-year-old Norwegian population: a cross-sectional study

Objectives
Measurement of tear film stability is central in dry eye disease (DED) diagnosis. In this study, we aimed to compare the performance of two methods of tear film stability measurement: non-invasive tear break-up time (NIBUT) and fluorescein tear film break-up time (FTBUT).

Design
Cross-sectional study.

Setting and participants
The study involved 132 subjects of 65-year-old inhabitants of the Oslo region who were not seeking ophthalmic care.

Interventions
The participants underwent a battery of DED tests, including NIBUT measured on Oculus Keratograph 5M and a traditional method using fluorescein drops (FTBUT). Oculus Keratograph 5M measures two types of NIBUT:; appearance time of the first dry spot (NIBUTFirst) and average NIBUTAvg.

Results
74 participants (56%) were female and 58 were male (44%). Subjects presented with varying degrees of DED signs and symptoms. Mean values of NIBUTFirst and FTBUT from all the participants were significantly different (6.2±4.9 s vs 8.6±6.2 s, p

Predictive value of burnout complaints and depressive symptoms for medically certified sickness absence among physicians in Sweden: a 1 year follow-up observational study

Objective
This study aimed to explore the predictive value of severe burnout complaints, symptom dimension of burnout and depressive symptoms for subsequent all-cause medically certified sickness absence (ACMCSA) during the pandemic among physicians in Sweden.

Design
A 1 year follow-up panel cohort observational study—the Longitudinal Occupational Health Survey for HealthCare in Sweden. At baseline (February–May 2021), a representative sample of 6699 physicians was drawn from the Swedish occupational register and invited to participate in the study. At follow-up (March–May 2022), the full sample (excluding those who died, retired, stopped working as a physician or migrated, n=94) was invited to answer the survey.

Setting
Swedish primary and specialist healthcare.

Participants
At baseline, the response rate was 41.3% (n=2761) of which 1575 also answered at follow-up.

Primary and secondary outcome measures
ACMCSA data came from the Swedish Social Insurance Agency. The Burnout Assessment Tool (BAT-23) was used to measure burnout, including a burnout total score and scores for the four symptom dimensions of exhaustion, mental distance, emotional impairment and cognitive impairment. Depressive symptoms were assessed using the Symptom Checklist-core depression (SCL-CD6). Associations between baseline burnout and depressive symptoms and subsequent ACMCSA were estimated with logistic regression analyses.

Results
ACMCSA was found in 9% of the participating physicians. In the sample, 4.7% had severe burnout complaints, and 3.7% had depressive symptoms. Burnout (OR=2.57; 95% CI=1.27 to 5.23) and the burnout symptom dimensions emotional impairment (OR=1.80; 95% CI=1.03 to 3.15) and cognitive impairment (OR=2.52; 95% CI=1.12 to 5.50) were associated with a higher likelihood of subsequent ACMCSA. Depressive symptoms were not associated with ACMCSA when adjusted for severe burnout complaints and other covariates.

Conclusion
This study demonstrates the distinction between burnout and depressive symptoms, particularly in predicting future ACMCSA. Early intervention targeting exhaustion and burnout may mitigate symptom development and reduce the risk of ACMCSA.

Recurrence of hypoglycaemia and associated factors among neonates admitted with perinatal asphyxia in Northwest Ethiopia: multicentre, retrospective follow-up study with negative binomial regression

Objective
To estimate the recurrence of hypoglycaemia and the associated factors in neonates with birth asphyxia admitted to the neonatal intensive care unit in Northwest Amhara region’s comprehensive specialised hospitals, Northwest Ethiopia, in 2024.

Design
A multicentre, institution-based, retrospective follow-up study.

Setting
Tertiary hospitals in Northwest Amhara Regional State, Northwest Ethiopia, from 1 July 2020 to 30 July 2024.

Participants
A total of 761 neonates with perinatal asphyxia were admitted to the neonatal intensive care unit of selected public hospitals in Northwest Amhara from July 2020 to July 2024.

Outcome measure
The primary outcome measure of this study was recurrence of hypoglycaemia. Furthermore, the factors associated with recurrence of hypoglycaemia in newborns with perinatal asphyxia were noted.

Results
The average number of hypoglycaemia cases among neonates with birth asphyxia was 2.05 (95% CI 1.939, 2.163) over the 28-day follow-up period. Meningitis (adjusted incidence rate ratio (AIRR)=1.16; 95% CI 1.04, 1.30), feeding in less than 72 hours (AIRR=1.17; 95% CI 1.05, 1.31), stage 3 hypoxic-ischaemic injury (AIRR=1.20; 95% CI 1.04, 1.39), length of hospital stay (AIRR=1.01; 95% CI 1.01, 1.03) and macrosomia (AIRR=1.39; 95% CI 1.19, 1.63) were significant factors associated with recurrence of hypoglycaemia.

Conclusions and recommendations
The current study indicated that the mean recurrence of hypoglycaemia in newborns experiencing perinatal asphyxia was considerably higher. Presence of neonatal meningitis, delayed initiation of feeding 72 hours after birth, stage 3 hypoxic-ischaemic injury, length of hospital stay and macrosomia were the key factors associated with recurrence of hypoglycaemia.

Protocol of the follow-up of patients with transthyretin amyloid cardiomyopathy by multimodality imaging (FAITH) study: a prospective observational study in patients with ATTR-CM undergoing treatment with tafamidis

Introduction
This prospective observational study of patients with transthyretin amyloid cardiomyopathy (ATTR-CM) undergoing treatment with tafamidis aims at identifying quantitative image markers and comparing imaging modalities regarding the follow-up and prognostication of these patients, with the goal of providing a multiparametric score to predict treatment response.

Methods and analysis
Patients with a board-approved decision to receive tafamidis will undergo, in addition to standard of care, baseline and follow-up cardiovascular magnetic resonance (CMR) scans at 9 and 18 months. In total, the study plans to recruit and scan 60 patients. A blinded read will take place in a CMR research core laboratory. The final statistical analysis will be based on developing a multiparametric score for the prediction of treatment response. The study will be managed through the Amyloidosis Center Charité Berlin, a clinical unit formed from the three clinical campus sites of the Charité in Berlin, using the Berlin Research Network for CMR.

Ethics and dissemination
The study was approved by the Charité—Universitätsmedizin Berlin ethics committee EA1/262/23. The results of the study will be disseminated through international peer-reviewed publications and congress presentations.

Trial registration number
Approved WHO primary register: German Clinical Trials Register: https://www.drks.de/DRKS00033884. WHO International Clinical Registry Platform: https://trialsearch.who.int/?TrialID=DRKS00033884. Recruitment started on 1 July 2024.

Cohort profile: the Genetics of Glucose regulation in Gestation and Growth (Gen3G) – a prospective prebirth cohort of mother-child pairs in Sherbrooke, Canada, 3-year and 5-year follow-up visits

Purpose
Initiated in 2010, the Genetics of Glucose regulation in Gestation and Growth (Gen3G) prospective cohort investigates the pathophysiology of impaired glycaemic regulation in pregnancy and evaluates its impact on both the mothers and her offspring health trajectory. Follow-up visits 3 and 5 years after delivery aimed to investigate pregnancy-related risk factors such as maternal obesity and gestational hyperglycaemia in relation to the mother’s metabolic health after pregnancy, and with offspring health outcomes such as risk of obesity and neurodevelopmental problems in early childhood. We also investigated molecular mechanisms involved in the fetal programming of these later health outcomes.

Participants
Of the 1024 women originally recruited in the first trimester of pregnancy, we have targeted the 854 who had complete glucose tolerance test data and the 724 newborns who provided placenta and/or cord blood samples for follow-up recruitment. Of these, 695 mother–child dyads agreed to be contacted for the prospective follow-up visits. 448 and 521 mother–child dyads completed the research visits at 3 and 5 years after delivery respectively.

Findings to date
At both visits, we collected the mother’s and child’s medical history, lifestyle (using validated questionnaires), sociodemographic status, anthropometric measurements, mother’s blood samples, child’s saliva samples and growth charts. At the 5-year-old visit, we additionally collected the mother’s and child’s urine and stool samples and the child’s blood samples; we performed a 75 g oral glucose tolerance test in the mothers and assessed the body composition in children using dual-energy X-ray absorptiometry. Using the Gen3G rich longitudinal data set, we have enhanced the understanding of the pathophysiology and characterisation of the heterogeneity of gestational diabetes mellitus, and we have shown that gestational hyperglycaemia and insulin resistance are associated with offspring epigenetics (DNA methylation) variations in the placenta, cord blood and blood at 5 years of age, as well as with offspring anthropometric, metabolic and neurodevelopmental outcomes in early childhood.

Future plans
We are currently conducting a prospective follow-up of mothers and their children 12 years after delivery to study how prenatal and early-life metabolic factors may programme childhood adiposity and obesogenic dietary behaviours. This follow-up should be completed by the end of 2026.
