Outcome Measures
Primary Outcomes (4)
Difference in dietary intakes
Difference in dietary intakes assessed by Food Frequency Questionnaire, a common method for measuring dietary intake in large epidemiological studies.
When subjects are enrolled
Difference in Dietary Inflammatory Index score
The Dietary Inflammatory Index (DII) score of the current nutritional status of patients with and without CSDH will be evaluated. The amounts of nutrients will be calculated using last 3-month nutrient analysis program. DII score will calculate from these foods. The z-score must first be calculated. To calculate the z-score, the standard global consumption amount is subtracted from the average consumption amount of the individual. The result obtained is divided by the standard deviation value. The z score found with this result is converted to the percentile score. The percentile value is multiplied by the full inflammatory effect score. DII is obtained as a result of summing the scores calculated for all nutrients. Found DII is an indicator of the inflammatory load of the individual's daily diet.
When subjects are enrolled
Difference in nutritional status
Difference in nutritional status measured by Mini-Nutritional Assessment.
When subjects are enrolled
Difference in frailty status
Difference in frailty status measured by Modified Frailty Index. Modified Frailty Index ranges from score 0 to 1, and frail status is defined as a score of ≥0.27.
When subjects are enrolled
Secondary Outcomes (2)
Difference in gut microbiota measured by 16S rRNA between case group and control group
When subjects are enrolled
Difference in metabolomics of gut, urine, and serum between case group and control group
When subjects are enrolled
Study Arms (2)
Case group (CSDH group)
CSDH patients recruited from neurosurgical department at 4 medical centres in China, which have apparent clinical symptoms and are confirmed by computed tomography or magnetic resonance imaging.
Control group (Healthy group)
non-CSDH, age- and gender-matched patients recruited from ophthalmology, otolaryngology, and physical examination department at 4 medical centres in China.
Interventions
Nutrition assessment, nutrient intake, dietary inflammatory index, and frailty status will be examined using questionnaires.
Neurological function, cognitive function, and life quality will be examined using Glasgow Coma Scale, Modified Rankin Scale, Markwalder Grade Scale, Mini-mental state examination, and EuroQol five dimensions questionnaire.
Collect peripheral blood samples from patients.
Collect urine and stool samples from patients.
Collect hematoma fluid, dura mater, and hematoma outer membrane samples from patients.
Eligibility Criteria
CSDH patients and non-CSDH, age- and gender-matched patients recruited from 4 medical centres in China.
You may qualify if:
- Patients (18 years to 90 years) presenting with clinical symptoms and neurological deficits of CSDH.
- CSDH verified on cranial computed tomography or magnetic resonance imaging.
- Written informed consent from patients or their next of kin according to the patient's cognitive status.
- Control group (Healthy group)
- non-CSDH patients (18 years to 90 years) with matched age and gender.
- Written informed consent from patients or their next of kin according to the patient's cognitive status.
You may not qualify if:
- Previous intracranial surgery for any neurological disorders but chronic subdural hematoma before.
- CSDH turned from acute subdural hematoma.
- Existing malignant tumors, poor medication condition or severe comorbidity.
- Difficulty in feeding requiring long-term enteral or parenteral nutrition support.
- Dietary and nutritional survey is estimated to be completed difficultly.
- Reproductive-age women without verified negative pregnancy testing.
- Participating in other research.
