Contribution Of Basal Cortisol Assay In The Exploration Of The Acute Phase Of Schizophrenia
Bibliographic record
Abstract
Introduction: Schizophrenia is a disabling mental disorder. Its diagnosis is often delayed because of the absence of specific biological markers. The role of cortisol in the pathology of schizophrenia remains controversial. Aims: To study the role of basal cortisol assay in the acute phase of schizophrenia.Methods: This was a cross-sectional case-control study conducted between June 2016 and July 2018 on antipsychotic-free schizophrenia patients compared to healthy controls. Patients were hospitalized at the psychiatric C department in Hedi Chaker University Hospital (UH) in Sfax. The diagnosis of schizophrenia was established according to DSM-5 criteria. The symptomsu2019 severity was evaluated according to the positive and negative syndrome scale. Cognitive functions were evaluated according to the Montreal Cognitive Assessment scale. The analysis of cortisol levels was performed in the laboratory of Biochemistry in Habib Bourguiba UH in Sfax.Results : This study included 45 patients and 100 male controls. The blood cortisol level was significantly higher in schizophrenia patients compared to controls. (140,12 u00b1 49,79 ng/ml vs 122,70 u00b1 40,77 ng/ml ; p=0,029). There was no significant difference between the two groups regarding salivary cortisol levels. There was a significant and negative correlation between salivary cortisol levels and the severity of negative symptoms. Positive and significant correlations were found between salivary cortisol levels and cognitive functions.Conclusion: This study allowed better understanding the role of basal cortisol assay in the acute phase of schizophrenia. Further research is needed to improve our knowledge about its role in the different phases of this disorder.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; both teacher heads agree on what is shown here.
