Positive 14-3-3 protein in cerebrospinal fluid followed by poppy-induced delayed post-hypoxic leukoencephalopathy: A case report.
Article in Heliyon, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Background: Delayed post-hypoxic leukoencephalopathy (DPHL) is characterized by a biphasic clinical course, with complete recovery from coma to a fully conscious state lasting one to four weeks (lucid interval), followed by abrupt neurological deterioration as an indirect consequence of hypoxic events like carbon monoxide poisoning and narcotic drug overdose. To our best knowledge, there are no documented cases in literature of choreoathetosis and dementia following poppy-induced DPHL with 14-3-3 protein in cerebrospinal fluid (CSF). Case presentation: We report the case of a 70-year-old female who underwent cardiopulmonary resuscitation (CPR) due to overdose of homemade refined opium poppy paste two weeks prior to presentation. She presented a progressive cognitive decline, along with the development of apraxia and choreic movement affecting her tongue and bilateral upper and lower extremities. During the symptomatic phase, brain magnetic resonance imaging (MRI) showed bilateral symmetrical hyperintense signals mostly in central frontal, temporal, and parieto-occipital lobes in the diffusion weighted imaging (DWI) and fluid-attenuated inversion recovery (FLAIR) sequences which are the characteristic findings of DPHL. CSF routine analysis, as well as toxicology screening, autoimmune and paraneoplastic encephalitis panels were negative, but the presence of 14-3-3 protein in the CSF was detected. With steroid therapy, hyperbaric oxygen therapy and symptomatic treatment, she experienced gradual improvement in cognition, motivation, and psychomotor function. Conclusion: DPHL represents a distinct form of encephalopathy characterized by unique clinical course and imaging features. It is the first report of DPHL with positive 14-3-3 protein in CSF. The potential of 14-3-3 protein as a biomarker for diagnosing DPHL and its ability to predict disease severity and prognosis warrants further research.
