Peri-arterial neural tissue surrounding the renal artery contributes to sympathetic overactivity in hypertension. During adrenal surgery, surgical peri-arterial neural dissection may interrupt these fibers and exert a renal denervation-like effect. Whether this maneuver improves postoperative blood pressure control remains unclear. We retrospectively reviewed 127 hypertensive patients who underwent adrenal surgery between January 2022 and March 2025. According to intraoperative findings, patients were classified into a surgical peri-arterial neural dissection group or a nondissection group. After 1:2 manual matching by age, sex, and hypertension duration, 54 patients were included. Postoperative hypertension remission and changes in antihypertensive medication use, quantified by the defined daily dose, were assessed. Multivariable logistic regression was used to explore factors associated with postoperative nonremission. Renal and adrenal function markers were compared between groups. The surgical peri-arterial neural dissection group had a higher remission rate than the nondissection group (50.0% versus 16.1%; P=0.008). Surgical peri-arterial neural dissection was independently associated with lower odds of postoperative nonremission (odds ratio, 0.150 [95% CI, 0.030-0.744]; P=0.020), supporting its potential role in improving postoperative blood pressure control. Patients in the dissection group showed greater reductions in antihypertensive medication use (median change in defined daily dose, -1.0 versus 0.0; P=0.006). Creatinine, blood urea nitrogen, cortisol, and adrenocorticotropic hormone levels were similar between groups. Surgical peri-arterial neural dissection performed during adrenal surgery was associated with improved postoperative blood pressure control and reduced medication burden without evidence of impaired renal or adrenal function.

Schizophrenia (SCZ) remains an etiological and therapeutic challenge, this article aims to explore the mediating role of lncRNA between chronic childhood stress and SCZ for providing a scientific basis of SCZ prevention. 200 SCZ patients and 200 healthy controls (HCs) were enrolled by convenience sampling. Positive and Negative Syndrome Scale (PANSS) and Childhood Chronic Stress Questionaire (CCSQ) were employed for mental assessment. lncRNA and cortisol level in peripheral blood were respectively detected by real-time quantitative reverse transcription PCR and enzyme-linked immunosorbent assay. The results showed scores of CCSQ, peer bullying (PB), abuse and neglect (AN), adverse life events (ALE) and cortisol were higher, while ΔCT values of NONHSAT089447 and NONHSAT021545 were lowered in SCZ patients (P < 0.05 or 0.01). Area under the curve of combined receiver operating characteristic curve for NONHSAT089447, NONHSAT021545, NONHSAT041499 was 0.814 with sensitivity and specificity of being 0.650, 0.880, respectively. Correlation analysis suggested scores of CCSQ, PB, AN, ALE as well as cortisol positively and ΔCT values of NONHSAT089447, NONHSAT021545 negatively correlated with scores of PANSS, positive symptom subscale (PSS), negative symptom subscale (NSS), general pathological symptom subscale (GPSS) in SCZ group (P < 0.05 or 0.01). NONHSAT089447 and NONHSAT021545 also played partial mediating roles between chronic childhood stress and psychotic symptoms with accounting proportions of 54.83% and 41.53% for total effect, respectively (P < 0.001). Taken together, we established a new model for SCZ in which exposure to chronic childhood stress could induce pathological process via mediating effects of NONHSAT089447 and NONHSAT021545.

The effects of short-term motivational factors and calisthenic exercise on blood cortisol levels, and symptoms of depression, anxiety, and stress in young adults: a randomized controlled trial

Aldosterone synthase deficiency (ASD), which is caused by a genetic defect in CYP11B2, involves a deficiency in aldosterone alone. Newborn and early childhood ASD patients can present with salt-wasting symptoms. In severe cases, this can lead to shock and be life-threatening. ASD must also be differentiated from another disease, pseudohypoaldosteronism type 1 (PHA1), which involves resistance to aldosterone. PHA1 can be classified into PHA1a, PHA1b, and secondary PHA1. PHA1a is caused by a heterozygous defect in NR3C2, which encodes the mineralocorticoid receptor. PHA1b is an autosomal recessive disorder caused by defects in the 3 epithelial sodium channel subunits α, β, and γ, encoded by SCNN1A, SCNN1B, and SCNN1G. Since ASD is a very rare disorder, the "The Intractable Adrenal Disorders Research by the Ministry of Health, Labour, and Welfare" developed the "Diagnostic criteria and severity classification for aldosterone synthase deficiency" to better understand the disorder. The criteria are as follows: Clinical symptoms: patient meets criteria 1 and 2. 1) Presents with salt-wasting symptoms (poor feeding, vomiting, dehydration, poor weight gain). 2) No skin pigmentation. Laboratory findings: patient meets criteria 1 through 3. 1) Low serum sodium and high serum potassium. 2) Low to normal plasma aldosterone and high plasma renin activity or high plasma active renin concentration. 3) No low blood cortisol level. Diagnoses of exclusion include PHA1, 21-hydroxylase deficiency, congenital lipoid adrenal hyperplasia, and congenital adrenal hypoplasia. We believe that the diagnostic criteria of ASD will enable clinicians and researchers to better understand congenital aldosterone deficiency.

Background: Tobacco smoking remains a leading cause of morbidity and mortality worldwide, with cadmium exposure, stress, and inflammation being key biological pathways involved in smoking-related diseases. This study evaluated blood levels of cadmium, serum cortisol, and C-reactive protein (CRP) in male smokers in Onitsha, Anambra State, Nigeria. Methods: A total of 180 male participants aged 18 years and above were recruited, comprising 105 smokers and 75 non-smokers. Data on demographics and smoking history (including number of cigarettes smoked per day) were obtained using structured questionnaires. Venous blood samples were collected and analyzed for blood cadmium, serum cortisol, and CRP using atomic absorption spectrophotometry and enzyme-linked immunosorbent assay (ELISA) methods. Parameters were compared between smokers and non-smokers, as well as among smokers stratified by age and quantity smoked. Correlation and regression analyses were used to explore relationships between cadmium and the other biomarkers. Results: Mean blood cadmium levels were significantly higher in smokers (3.82 ± 1.14 µg/L) compared to non-smokers (1.27 ± 0.64 µg/L; p = 0.001). Similarly, mean cortisol levels were elevated in smokers (21.6 ± 5.3 µg/dL) versus non-smokers (14.3 ± 4.2 µg/dL; p = 0.0001), as was CRP (4.85 ± 1.67 mg/L in smokers vs. 2.01 ± 1.08 mg/L in non-smokers; p = 0.002). Among smokers, older age groups (&gt;45 years) and those smoking more than 10 cigarettes per day showed significantly higher levels of all three parameters (p &lt; 0.05). Cadmium was positively correlated with cortisol (r = 0.61, p = 0.0001) and CRP (r = 0.54, p = 0.0001). In multiple regression analysis, cadmium was a significant predictor of both cortisol (β = 0.58, p = 0.0001) and CRP (β = 0.49, p = 0.0001), after adjusting for age and quantity smoked. Conclusion: This study demonstrates that male smokers in Onitsha have significantly elevated blood levels of cadmium, serum cortisol, and CRP, with cadmium showing strong associations with stress and inflammatory biomarkers. These findings emphasize the systemic toxicological burden of smoking and the need for targeted public health interventions in this population.

This prospective, single-center, case-control study investigated circulating autoantibodies (AAbs) targeting G protein-coupled receptors (GPCRs) in Long COVID (LC) patients to identify potential diagnostic biomarkers and therapeutic targets. Fifteen participants were enrolled at the LC clinic in Rome: eleven with severe LC-defined as >4 persistent symptoms (fatigue, cognitive impairment, poor exercise tolerance, dyspnea, arthralgia, or dysautonomic manifestations) >3 months post-infection-and four asymptomatic post-COVID (APC) individuals. Fatigue was assessed using the Fatigue Assessment Scale (FAS ≥ 22; severe ≥ 35). Auto-Abs against AT1R, endothelin receptor A, adrenergic (α1, α2, β1, β2), and muscarinic (M1-M5) receptors were quantified, along with blood cortisol and ACTH levels. SARS-CoV-2-specific T-cell responses to Spike and Nucleocapsid proteins were evaluated by ELISpot assay. In our small cohort, LC patients were younger, had fewer comorbidities (p = 0.03), fewer vaccine doses (p = 0.03), and higher FAS scores (33 vs. 12; p = 0.001). Mean GPCR AAbs levels were higher in LC than in APC (8.88 vs. 5.45 Units/mL; p = 0.17), indicating a coherent autoimmune signature in LC that correlates with symptom development. Morning cortisol was lower in LC (12.7 vs. 17 mg/dL; p = 0.01), and T-cell responses tended to be weaker. These findings suggest GPCR AAbs may serve as biomarkers and therapeutic targets for a subset of patients, guiding diagnosis and treatments with IV immunoglobulin or immunoadsorption.

This study investigates the effects of physical activity on serum cortisol levels and phagocytic capacity of the innate immune system in eight common bottlenose dolphins under human care. Analysis of 8 pairs (16 samples) revealed a significant increase in cortisol during periods of physical activity (mean increase of 1.27 µg/dL, 122% elevation), accompanied by decreased phagocytosis in granulocytes (92% reduction) and monocytes (52% reduction). Statistical analyses demonstrated consistent negative correlations between cortisol levels and phagocytic function, suggesting that physical activity influences hypothalamic-pituitary-adrenal axis activation and, consequently, innate immune system function. The male showed an attenuated cortisol response, but maintained monocyte sensitivity. These findings highlight the complex interplay between the neuroendocrine cortisol response and immune function in cetaceans, for the management and evaluation of animals under human care. A multi-method statistical framework incorporating Bayesian analysis, bootstrapping, and traditional approaches ensured robust inference despite limited sample size.

Red seabream (Pagrus major) reared under intensive rearing conditions faces hypermelanosis and dyspigmentation, resulting in darker and less pink/red skin color, losing the natural appearance of the species. This has a great negative impact on consumers' acceptance and market appeal. Two experiments were performed to test the effect of the source, level, and feeding duration of astaxanthin supplementation in the feed on red seabream skin color reversing the depigmentation problem. Firstly, three different sources of astaxanthin (artificially synthesized, algal-extracted, and yeast-extracted astaxanthin) at the same inclusion level (100 mg kg-1 feed) were tested. Then, the best performing source was tested using five inclusion levels (0, 20, 60, 80, and 100 mg kg-1) in the feed for 60 days. At the same time, growth performance, blood biochemical parameters, antioxidant capacity and cortisol levels were also assessed. The results showed that red seabream appearance can be significantly improved with the inclusion of astaxanthin from the algae Haematococcus pluvialis in the feed even at lower levels compared to the artificially synthesized astaxanthin for a 60-day period. Fish growth performance and blood parameters were not affected by any of the experimental treatments.

This study aimed to evaluate the chronic impact of occupational noise exposure on physiological and psychological outcomes, including blood pressure, cortisol levels, aggression, and auditory annoyance, among petrochemical workers. A cross-sectional study, in 2025, was conducted on 300 petrochemical workers. Participants were divided into two groups, including 130 workers exposed to noise levels lower than 85A‑weighted decibels (dB(A)) and 170 workers exposed to noise levels higher than 85 dB. Then, data related to demographic parameters, noise levels (using Casella CEL 815 sound level meter), blood pressure, salivary cortisol level (using measured using the enzyme‑linked immunosorbent assay), and psychological outcomes (using validated questionnaires for annoyance and aggression) were collected. Statistical analyses included independent t -test, Pearson correlation, and multivariate regression. Workers exposed to noise higher than 85 dB compared to individuals exposed to lower than 85 dB had significantly higher systolic blood pressure (SBP) (133.67 ± 10.33 mmHg vs. 119.99 ± 9.41 mmHg, P < 0.001) and diastolic blood pressure (91.79 ± 3.92 mmHg vs. 82.76 ± 3.84 mmHg, P < 0.001), total aggression scores (122.45 ± 11.92 vs. 76.06 ± 9.85, P < 0.001), and cortisol level (22.09 ± 3.96 µg/dL vs. 14.23 ± 3.09 µg/dL, P < 0.001). Auditory annoyance (8.48 ± 1.63 vs. 4.40 ± 1.41, P < 0.001) mediated 53% of the noise effect on SBP and 48% of its effect on cortisol level. Chronic noise exposure can significantly affect cardiovascular and mental health of petrochemical workers, with annoyance as a key mediating factor. These findings underscore the importance of noise reduction strategies and regular health monitoring to decrease occupational health risks.

Genome-wide association study of tolerance to acute hypoxia in the olive flounder (Paralichthys olivaceus) using individual blood cortisol levels as a physiological phenotype.

ObjectThis study assessed the prevalence and associated psychosocial and biological factors of non-suicidal self-injury (NSSI) in Chinese child and adolescent inpatients diagnosed with major depressive disorder (MDD) by DSM-5 criteria.MethodsThis cross-sectional study included 177 inpatients aged 10–16 years. Participants were assessed using the Childhood Trauma Questionnaire (CTQ), Hamilton Depression Scale (HAMD-24), Hamilton Anxiety Scale (HAMA), Shame Scale for Middle School Students (SS), and Mobile Phone Addiction Index (MPAI). Fasting blood levels of cortisol, thyroid hormones, and inflammatory markers were measured. Group comparisons (NSSI vs non-NSSI) used t-tests and chi-square tests, followed by binary logistic regression to identify independent associated factors of NSSI.ResultsNSSI prevalence was 69.49%, with a higher proportion of females in the NSSI group. Compared to the non-NSSI patients, the NSSI group exhibited significantly higher scores on the HAMD-24, HAMA, shame, and MPAI scales, as well as higher cortisol and lower free triiodothyronine (FT3) levels. No significant differences were found in other biomarkers (Hypersensitive C-reactive protein, FT4, T3, T4, TSH, Adrenocorticotropic hormone). Regression analysis identified emotional neglect (OR = 1.223), depression severity (OR = 1.197), anxiety (OR = 1.186), shame (OR = 1.046), and cortisol (OR = 1.081) as significant factors associated with NSSI. Smartphone addiction and thyroid function-related indicators showed no significant association in the regression model.ConclusionNSSI is highly prevalent among child and adolescent inpatients with MDD and is associated with emotional neglect, depressive and anxiety symptoms, shame-proneness, and dysregulated cortisol levels. Smartphone addiction and other biological markers (Hypersensitive C-reactive protein, FT4, T3, T4, TSH, and Adrenocorticotropic hormone) showed no independent association with NSSI in the final model. These findings highlight the importance of integrated management of psychological and biological indicators in high-risk children and adolescents.

Low social status leads to chronic social stress that predicts risk for physical and mental illness, especially when it starts early in life. To examine the longitudinal effects of low social status on the immune system, this study assessed the effects of low social status on developmental secretory patterns of pro- and anti-inflammatory markers under baseline conditions, as well as in response to an immune challenge (lipopolysaccharide (LPS)-induced activation of pro- and anti-inflammatory cytokines) in a translational rhesus monkey model of lifelong social subordination stress. Baseline blood samples were collected in 27 socially housed female rhesus monkeys (13 dominants, DOM, and 14 subordinates, SUB) during infancy (6 months), the juvenile pre-pubertal period (16 months), and adulthood (9–10 years) to examine the longitudinal effects of social status on inflammatory markers in unstimulated versus LPS-stimulated conditions mimicking exposure to bacterial infection. Basal levels of the stress hormone cortisol in blood were measured to examine associations between inflammation and activity of the hypothalamic–pituitary–adrenal (HPA) axis throughout the life span. Basal peripheral levels of inflammatory markers (e.g., IL-6) increased across development in both SUB and DOM animals with no significant differences. Basal cortisol levels were significantly higher in infancy as compared to adulthood, but no significant effects of social rank were detected. However, in adulthood, SUB animals showed a cytokine-specific immune response to ex vivo LPS stimulation with significantly higher secretions of IL-1β, IL-2, and IL-10 compared to DOM animals, whereas IL-8 response to LPS was lower in SUB animals than in DOMs. This cytokine-specific response to an immune challenge that mimics bacterial infection could reflect dysregulated immune cells that may have short-term adaptation, but at the cost of longer-term risks for low-grade chronic inflammation and accelerated immune aging for socially subordinate female macaques.

IntroductionLong COVID (LC) has been associated with hypothalamic–pituitary–adrenal (HPA) axis dysfunction, although findings from blood cortisol measurements remain inconsistent. We hypothesized that LC patients exhibit a disrupted diurnal cortisol rhythm and that salivary cortisol (SC) profiling may provide a more accurate assessment of HPA activity.MethodsThis prospective, single-center, case–control study was conducted at a Long COVID clinic in Rome between February 2023 and March 2024 and included 96 participants evaluated at least 28 days after confirmed SARS-CoV-2 infection. LC was defined as one or more new or persistent symptoms and classified as severe when four or more of the following were present: fatigue, cognitive impairment, exercise intolerance, dyspnea, arthralgia, or dysautonomia. SC was measured at 8:00 AM, 3:00 PM, and 11:00 PM.ResultsThe cohort (mean age 58.1 ± 14.8 years; 60% female; all White) included 83 LC patients (80% moderate, 20% severe) and 13 asymptomatic post-COVID (APC) individuals. Compared with healthy controls, both LC and APC groups showed reduced morning SC (p<0.01), flattened diurnal variation, and elevated evening SC, indicating loss of the normal morning peak and nocturnal decline. Blood cortisol levels did not differ among groups, but LC patients had higher ACTH than APC (26 pg/mL vs 13 pg/mL; p<0.01), suggesting compensatory HPA activation. One LC patient (1.2%) was diagnosed with adrenal insufficiency.DiscussionThese exploratory findings suggest a disrupted circadian cortisol rhythm in individuals after COVID-19, with altered HPA axis dynamics that may be associated with disease severity.

Objective: This study aimed to design and evaluate the effectiveness of a mindfulness-based psychological coping skills training package in reducing stress and cortisol levels and enhancing psychological self-efficacy among women with breast cancer. Methods and Materials: The study employed a mixed-methods design in two phases. In the qualitative phase, semi-structured interviews with 12 patients and psychology experts, alongside thematic analysis and literature review, were conducted to identify core dimensions of coping needs. The content and structure of the package were developed and validated using the Delphi method with 15 experts. The final program comprised ten 90-minute sessions focusing on mindfulness practice, adaptive coping strategies, and stress management skills. In the quantitative phase, a quasi-experimental design with pretest–posttest, control group, and two-month follow-up was applied. Thirty women with breast cancer, aged 20–45, were purposively sampled and randomly assigned to experimental (n = 15) and control (n = 15) groups. Data collection involved the Perceived Stress Scale, the Psychological Self-Efficacy Scale, and blood cortisol measurement. Data were analyzed using repeated measures ANOVA in SPSS 26. Findings: The intervention group showed a significant reduction in perceived stress scores compared to the control group (p &lt; .001), with improvements sustained at follow-up. Cortisol levels also decreased significantly in the experimental group across posttest and follow-up (p &lt; .001). Psychological self-efficacy scores increased markedly after the intervention (p &lt; .001), indicating enhanced coping capacity. The interaction effects confirmed that improvements were specific to the experimental group. Conclusion: The mindfulness-based coping skills training package effectively reduced stress and cortisol levels and improved psychological self-efficacy in women with breast cancer, underscoring its potential as a complementary intervention to enhance psychological adaptation and overall quality of life in oncology care.

Mediating role of maternal cortisol in the association between maternal serum creatinine and fetal cortisol exposure.

Sepsis is a life-threatening organ dysfunction due to dysregulation of the body's immune response to infection. The Sequential Organ Failure Assessment score (SOFA score) is a diagnostic tool used to quantitatively and objectively assess the level of organ dysfunction. Sepsis as a stressor of systemic inflammation, causes an increase in cortisol secretion by the adrenals to target tissues, which suppresses inflammation. Objective: To determine the correlation between SOFA score and blood cortisol levels in sepsis patients at RSUP Dr. M. Djamil Padang. Method: Observational analytic study with a cross-sectional method. The sample consisted of 55 patients who had been diagnosed with sepsis. The data used was secondary data from medical records. The data were tested using the Spearman correlation test. Result: A correlation was found between the SOFA score and blood cortisol levels, yielding a correlation coefficient of r = 0.338 and a p-value of 0.012. Conclusion: There is a significant moderate correlation between SOFA scores and blood cortisol levels. Keywords: blood cortisol, sepsis, SOFA score

In response to new and emerging challenges in animal transport, including more stringent biosecurity and public demand for enhanced animal welfare, an innovative prototype trailer with mechanical ventilation and air filtration systems was developed. The performance of the trailer in maintaining acceptable environmental conditions for the pigs during transport in both cold and warm weather was evaluated through a series of road tests. In these tests, the general welfare of the animals during transport was also assessed. Results showed that temperatures inside the animal compartment during cold ambient conditions were above 10 °C for more than 60 to 90% of the trip despite the frequent occurrence of cold temperatures (below 0 °C) at the inlet. On the other hand, the temperature in the animal compartment ranged from 16 to 19.4 °C most of the time during transport in warm weather. The average moisture levels in the animal compartment ranged from 4.15 to 6.3 g/kg dry air and 5.05 to 78.8 g/kg dry air during cold and warm transport conditions, respectively, which is comparable to the humidity ratios measured in conventional pig transport trailers. Carbon dioxide concentration inside the animal compartment ranged from 912 to 1192 ppm in cold conditions and from 1008 to 1414 ppm in warm weather, indicating good air quality in the trailer during transport. Furthermore, there was no significant change in the levels of blood cortisol and in the rectal and body temperatures of pigs measured at the start and end of each monitoring trip, indicating that the pigs showed reduced or minimal stress during transport. The study demonstrated that the trailer design with a mechanical ventilation system significantly improved the thermal comfort and environmental conditions for pigs, contributing to their welfare during transport.

This study investigates the relationship of specific brain regions with pattern separation, pattern completion, and visual processing speed, along with their relationships with basal metabolic markers like cortisol and glucose. Three-dimensional MR images from 39 medical students were analyzed on volbrain.net. Cortisol and glucose levels were measured in morning fasting blood samples. Participants underwent tests for pattern separation, pattern completion, and visual processing speed. There was a positive correlation between the pattern separation test score and the left anterior and middle cingulate gyrus volumes (r = 0.400, p = 0.012; r = 0.355, p = 0.026, respectively). The right and left thalamus volumes positively correlated with the pattern completion test score (r = 0.336, p = 0.046; r = 0.321, p = 0.046, respectively). Visual Search Response Latency was negatively correlated with the right precuneus volume (r = −0.455, p = 0.045). The pattern separation test score and blood cortisol levels were positively correlated (r = 0.572, p = 0.032). The role of extrahippocampal regions, specifically the Papez circuit elements such as the cingulate gyrus and amygdala, in pattern separation and completion is highlighted in this work.

BackgroundLonger-term effects of chiropractic care on neuroplasticity, stress, and immune biomarkers remain unclear.ObjectiveThis study evaluates the effects of chiropractic care on physiological biomarkers, including brain-derived neurotrophic factor (BDNF), cortisol (saliva, blood, hair), and inflammatory cytokines [interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-α), interferon-gamma (IFN-γ), C-reactive protein (CRP), B-lymphocytes (CD19), T-helper cells (CD4), cytotoxic T cells (CD8), and natural killer cells (CD56)] in subclinical spinal pain patients.MethodsParallel-group, pragmatic randomized controlled trial conducted at the Rehabilitation Center of Railway General Hospital, Rawalpindi, Pakistan. Intervention: 12 weeks; follow-up: 16 weeks (May–December 2022). Participants with subclinical spinal pain were randomly assigned by using simple lottery method to either 12 weeks of chiropractic or sham care. We aimed to recruit up to 150 participants over three months; however, given the pragmatic nature of the trial and logistical constraints, including the availability of chiropractors, the final number enrolled was determined by how many eligible participants could be recruited during this time. Adults aged 20–60 years with subclinical spinal pain (n = 106 randomized; 88 completed 12-week measures; 73 completed 16-week follow-up). Among those who finished 12 weeks: chiropractic, 26 males/15 females, mean age 37.49 ± 12.39 years; sham, 24 males/23 females, mean age 26.85 ± 7.13 years. The primary outcome blood BDNF and secondary outcome, including saliva, blood and hair cortisol, IL-6, TNF-α, IFN-γ, CRP, CD19, CD4, CD8, and CD56 levels were measured at baseline, after 12 weeks of intervention, and at a 16-week follow-up. Linear and linear mixed-effects regression models were used to assess the effect of care and time on biological measures.ResultsSignificant between-group differences were observed after 12 weeks of intervention, with higher salivary cortisol 5 ± 2 [0, 10], p = 0.045 and blood BDNF150 ± 60 (40, 270), p = 0.009 and IL-6 1.0 ± 0.3 [0.5, 1.5], p < 0.001 levels in the chiropractic care group. At the 16-week follow-up, blood cortisol −9 ± 4 [−17, −1], p = 0.024, IFN-γ − 22 ± 7 [−35, −9], and TNF-α −2 ± 1 [−5, 0], p = 0.028 levels increased in the sham group. Within-group comparisons showed a non-significant 10 ± 20 [−20, 50], p = 0.439 reduction in hair cortisol levels in the chiropractic group at 12 weeks, along with increased levels of blood cortisol, BDNF, CD8, CD4, IL-6, and CD19.Conclusion12 weeks of Chiropractic care modulates biomarkers linked to neuroplasticity, inflammation, and stress. Increases in brain-derived neurotrophic factor and interleukin-6 suggest enhanced neuroplasticity and inflammatory responses, while decreases in tumor necrosis factor-alpha indicate a regulatory effect on systemic inflammation. These findings support the notion that chiropractic care modulates physiological systemic biomarkers, which may underscore its benefits on clinical outcomes.Trial registrationClinicalTrials.gov NCT05369156.
