To evaluate the effectiveness of a web-based secondary prevention programme for postpartum depression, delivered with or without telephone support, compared with usual care.

We first conducted a randomised controlled superiority trial to test whether the web-based Parents and Babies programme (Toi, Moi, Bébé; TMB) delivered with motivational telephone support (ie, coaching) was superior to the fully automated programme (ie, self-help). TMB incorporated classic and third-wave cognitive–behavioural therapy components and psychoeducation. Then, we tested whether TMB (both treatment modalities combined) was superior to usual care. The usual care comparison group was drawn from the CONCEPTION prospective pan-Canadian perinatal cohort (N=592).

A remote study based at Sainte-Justine Hospital Centre, Quebec, Canada.

Web-based intervention programme participants were women aged ≥14 years at 12–25 weeks’ gestation, with subclinical to moderate clinical Edinburgh Postnatal Depression Scale (EPDS) scores: 9–16. Exclusion criteria were psychosis and self-reported substance abuse. The usual care comparison group was pregnant women ≥18 years old. All participants were living in Canada at study inception.

The primary outcome was EPDS scores at 3 months post partum, accounting for baseline EPDS scores and depression events defined as EPDS ≥13 at 3 months post partum. The secondary outcomes were EPDS scores at 6 months post partum, depression events (EPDS≥13) at 6 months post partum, anxiety symptoms (Generalised Anxiety Disorder 7-item Scale, GAD-7) at 3 and 6 months post partum, accounting for baseline scores for the continuous outcomes; as well as the number of completed intervention modules and well-being scores (WHO 5-Item Well-being Index) at 3 months post partum.

We randomised 510 participants to TMB self-help (n=255) or TMB with coaching (n=255); 211 and 214 participants, respectively, were included in the complete-case intention-to-treat analyses. At baseline, 91% lived with a partner, 71% were university graduates and 42% self-reported GAD-7≥10. Randomisation was successful. First, TMB with coaching was not superior to TMB self-help: at 3 months post partum, EPDS scores were TMB self-help (mean 8.0±4.3) vs TMB with coaching (mean 8.6±4.5); effect size was 0.01 (95% CI 0.00 to 0.03; p=0.16). Second, TMB (regardless of intervention arm) was superior to usual care: in adjusted regression models, EPDS scores were 6.2 units lower (per SD, 95% CI –8.2 to –4.3) in TMB (both treatment modalities combined) than in usual care; and proportions of depression events were 4.7 units lower (per SD on the logit scale, 95% CI –6.6 to –2.7) in TMB (combined) than in usual care. No other group differences were observed.

Our findings suggest that, in women with subclinical to moderate clinical antenatal depressive symptoms, receiving a web-based cognitive–behavioural therapy-based programme in addition to usual care can reduce depression postnatally.

To investigate whether pneumoconiosis increases the risk of cataract.

Nationwide population-based retrospective cohort study.

Taiwan’s National Health Insurance database, which covers >99% of the population.

The study included 19 841 adults newly diagnosed with pneumoconiosis between 2001 and 2020 and 79 364 age-matched and sex-matched individuals without pneumoconiosis. Participants with a prior history of cataract were excluded.

The primary outcome was incident cataract identified through International Classification of Diseases diagnostic codes. Subgroup analyses were performed to evaluate cataract risk across different strata of age, sex and comorbidity. In addition, among patients with pneumoconiosis, we conducted a secondary analysis evaluating the association between systemic corticosteroid use and cataract development.

During follow-up, the incidence of cataract was significantly higher in the pneumoconiosis cohort (38.9 vs 35.3 per 1000 person-years). Patients with pneumoconiosis had an increased risk of cataract after adjustment for age, sex and comorbidities (adjusted HR (aHR)=1.22, 95% CI 1.18 to 1.26). Elevated risks were observed in both men (aHR=1.22, 95% CI 1.18 to 1.26) and women (aHR=1.20, 95% CI 1.13 to 1.29). All age groups showed increased risks, with the highest estimate observed among patients aged ≥75 years (aHR=1.24, 95% CI 1.19 to 1.30). Subgroup analyses showed an increased risk in patients with pneumoconiosis who had no comorbidities (aHR=1.12, 95% CI 1.07 to 1.18). In a secondary analysis, systemic corticosteroid exposure was not significantly associated with cataract development (adjusted OR=0.65, 95% CI 0.39 to 1.09).

Pneumoconiosis is associated with an increased risk of cataract. Routine ophthalmologic surveillance should be considered in pneumoconiosis management.

This study aimed to investigate the evolution of burnout levels and cardiovascular risk among healthcare professionals during the COVID-19 pandemic, identifying associated risk factors, with a particular focus on the impact of working hours, job roles and working units.

A longitudinal, observational study was conducted.

The study was carried out in a medical centre in central Taiwan, encompassing various healthcare settings.

A total of 1502 healthcare workers participated, including nurses, medical technicians, resident doctors, attending physicians and administrative staff. Participants were selected based on consistent completion of a 4-year questionnaire, with exclusion criteria for those who did not complete.

The primary outcome measured was burnout levels using the Chinese version of the Copenhagen Burnout Inventory. The secondary outcome was cardiovascular risk calculated from employees’ health check-up data using the Framingham Risk Score.

Cardiovascular risk showed an upward trend over 4 years. Personal and work-related burnout significantly decreased from 2019 to 2020 but increased from 2020 to 2022, aligning with changes in weekly working hours. Nurses exhibited the most pronounced fluctuations, likely due to their younger average age, shorter professional tenure and frequent direct patient contact, which may heighten vulnerability to pandemic-related stressors. In contrast, attending physicians demonstrated age as a protective factor against burnout, as greater seniority, clinical experience and professional maturity may buffer stress and foster resilience. Participants who worked in COVID-related units generally had elevated burnout levels and working hours. During the initial outbreak in 2020, employees working in COVID-related units had reduced working hours but stable burnout levels, while employees in non-COVID-related units experienced decreased burnout.

This study highlights the critical impact of long working hours on burnout among healthcare professionals during the COVID-19 pandemic. Nurses emerged as a vulnerable group, sensitive to pandemic-induced changes, while attending physicians exhibited more resilience. COVID-related units face greater stress and are less likely to benefit from reductions in patient numbers and working hours during the pandemic. Our findings underscore the urgent need for tailored interventions, such as regulated work hours, flexible scheduling and enhanced organisational and peer support, to protect healthcare workers’ well-being. These strategies can strengthen workforce resilience and sustainability in future public health crises.
