Psychological Distress, Resilience, and Immunoinflammatory Signatures in Healthcare Workers During COVID-19.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The COVID-19 pandemic has profoundly affected healthcare workers, increasing vulnerability to neuropsychiatric disorders, such as anxiety and depression. Psychological distress may be shaped by resilience, coping behaviours, and immune dysregulation. We investigated psychological distress symptoms, resilience, alcohol use, and cytokine profiles in 1440 workers from four hospitals in Fortaleza, Brazil. Participants were classified as frontline or second-line workers and assessed with the SRQ-20, CD-RISC, and AUDIT. Blood samples were analysed for SARS-CoV-2 antibodies and cytokines. Data were collected at two time points (August-October 2021; March-April 2022). Frontline workers reported higher distress, with decreased vital energy and somatic symptoms most prominent. Lower resilience scores correlated with all SRQ-20 domains, while higher alcohol use was linked to decreased energy and depressive thoughts. Reduced anti-spike antibody levels were also associated with greater distress. COVID-19 infection and symptom severity were associated with more persistent mental distress symptoms. Sex-specific immune signatures emerged: in women, lower interleukin (IL)-7 and C-X-C motif chemokine ligand 9 (CXCL-9) and higher IL-27 correlated with depressive-anxious mood and energy depletion; in men, IL-18, IL-9, and tumour necrosis factor beta (TNF-β) were positively associated with distress. This study demonstrates that psychological distress among healthcare workers during COVID-19 was shaped by resilience, alcohol use, infection severity, and sex-dependent immune alterations. Strengthening resilience and targeting inflammatory pathways may help mitigate the long-term mental health burden in this workforce during future public health crises.
