The use of complementary and alternative medicine for patients with traumatic brain injury in Taiwan

Can alternative medical methods evoke somatosensory responses and functional improvement?

Background

Evidence-based scientific studies focusing on complementary alternative medicine (CAM) and potential functional improvement after an insult of the central nervous system are lacking.

Aims

We aim to demonstrate that functional recovery after stimulation applied as a CAM treatment through cauterization might trigger neural repair and regenerative paths similarly as acupuncture, cupping, electrical or magnetic stimulations. Those paths are important in recovery of function.

Procedures

Medical records and information of ten patients, with initial presentations of cerebral trauma or spinal cord insult inducing paralysis, were studied. Patients ages ranged from 17 to 95-year-old. Patients consulted for alternative medical treatment one year or more after initial diagnosis.CAM treatment consisted in 10-point stimulation on the skull and 4-point stimulation located at the right and left calves and forearms. Stimulations consisted of a heated steel rod application (cautery) in a one-time session. The duration of each stimulation was about 0.5 s.

Results

Most studies using CAM stimulations (acupuncture, cautery, cupping, moxibustion, electrical and magnetic stimulations) describe improvement. In all 10 medical records and information from our practitioner, patients had improvement in their motor skills, including gain of weight support, unassisted small walks, independent and voluntary movements of limbs. Improvement was steady over a period of one to several years.

Conclusion

We compared our findings to acupuncture, electrical, magnetic field effects to highlight common paths and to provide scientific evidence for recovery of the function. We believe that CAM treatments triggered existing or new neuronal networks as well as synaptic efficiency or reactivation, through highly increased, sensory nociceptive coupled to proprioceptive, afferences. Those results also highlight the need to further investigate neural function of cortical and subcortical areas through indirect pathways stimulations.

A Modern Approach to the Treatment of Traumatic Brain Injury

Background: Traumatic brain injury manifests itself in various forms, ranging from mild impairment of consciousness to severe coma and death. Traumatic brain injury remains one of the leading causes of morbidity and mortality. Currently, there is no therapy to reverse the effects associated with traumatic brain injury. New neuroprotective treatments for severe traumatic brain injury have not achieved significant clinical success. Methods: A literature review was performed to summarize the recent interdisciplinary findings on management of traumatic brain injury from both clinical and experimental perspective. Results: In the present review, we discuss the concepts of traditional and new approaches to treatment of traumatic brain injury. The recent development of different drug delivery approaches to the central nervous system is also discussed. Conclusions: The management of traumatic brain injury could be aimed either at the pathological mechanisms initiating the secondary brain injury or alleviating the symptoms accompanying the injury. In many cases, however, the treatment should be complex and include a variety of medical interventions and combination therapy.

Effect of Acupuncture on Recovery of Consciousness in Patients with Acute Traumatic Brain Injury: A Multi-Institutional Cohort Study

Traumatic brain injury (TBI) causes cognitive dysfunction and long-term impairments. This study aims to examine the effectiveness of acupuncture on the recovery of consciousness in TBI patients. This is a retrospective, multi-institutional cohort study. We enrolled patients with newly diagnosed TBI from 1 January 2007 to 3 August 2021, aged 20 years and older, from the Chang Gung Research Database (CGRD). The outcome was defined based on the difference between the first and last Glasgow Coma Scale (GCS). A total of 2163 TBI patients were analyzed, and 237 (11%) received acupuncture in the treatment period. Generally, the initial GCS was lower in the acupuncture users (11 vs. 14). For the results of our study, a higher proportion of acupuncture patients achieved significant improvement (GCS differences ≥ 3) compared to non-acupuncture users (46.0% vs. 22.4%, p-value < 0.001). The acupuncture users had a 2.11 times higher chance of achieving a significant improvement when considering all assessable covariates (adjusted odds ratio (aOR) 2, 11, 95% confidence interval [CI]: 1.31-3.40; p-value = 0.002). Using 1:1 propensity score matching (PSM), the acupuncture users still had better outcomes than the non-acupuncture users (45.3% vs. 32.9%, p-value = 0.020). In conclusion, this study suggests that acupuncture treatment may be beneficial for TBI patients.

Alternative medicine therapies in neurological disorders: Prevalence, reasons and associated factors. A systematic review

OBJECTIVE

This systematic review aimed to identify the prevalence of CAM use in patients with neurological disorders, and also to know most frequent types of CAM used.

METHODS

Five databases: PubMed, Science Direct, EBSCO, Latindex and Scielo (in English and Spanish) were searched from January 2010 to May 2021. Only original cross-sectional, retrospective and cohort studies were included, whose primary objective was to describe the frequency of CAM use in neurological disorders and/or the related factors to its use in adults. Based on the data, a descriptive analysis was performed, covering the characteristics of studies, measuring methods, prevalence, types and related factors. To control the risk of bias, a quality assessment of each study was performed using STROBE checklist.

RESULTS

For the final analysis, 40 studies were included. Most common pathologies observed in the studies were multiple sclerosis, headache, stroke, Parkinson and epilepsy. The STROBE score of studies ranged from 13 to 22 points, with an average of 18.2. Prevalence of CAM use was highly variable from one study to another (16% in stroke patients, to 100% in amyotrophic lateral sclerosis or spinal cord injury patients). Biological therapies (dietary supplements and herbal medicine) were the most commonly CAM types used. The associated factors identified were female sex, an age between 40 and 50 years, and higher socioeconomic level. Not all studies investigated about the results of CAMs but these ranged from 35% to more than 80% of reporting positive effects.

CONCLUSIONS

The prevalence of CAM use in neurological diseases is highly variable (16%-100%); the most used type of CAM was biological therapies and the associated factors were female sex, age between 40 and 50 years old and high socioeconomic level.

A systematic review of communication about Complementary and Integrative Health (CIH) in global biomedical settings

OBJECTIVES

A systematic review to analyze communication rates of complementary and integrative health (CIH) and analyze how communication terms, such as "disclosure," are measured and operationalized.

METHODS

We searched seven databases for studies published between 2010 and 2018 with quantitative measurements of patients' communication of CIH to a biomedical clinician. We analyzed communication terms used to describe patients reporting CIH usage. We also examined the conceptual and operational definitions of CIH provided and whether those terms were explicitly operationalized. We aggregated the percentage, rate, or ratio of CIH users that communicated about CIH with their clinicians by disease type and geographical region.

RESULTS

7882 studies were screened and 89 included in the review. Studies used a wide range of conceptual and operational definitions for CIH, as well as 23 different terms to report communication related to reporting CIH usage. Usage varied by disease type and geographical region.

CONCLUSIONS

Studies of CIH and CIH communication may measure different kinds of social and communicative phenomena, which makes comparison across international studies challenging.

PRACTICE IMPLICATIONS

Future studies should employ standardized, replicable measures for defining CIH and for reporting CIH communication. Clinicians can incorporate questions about prior, current, and future CIH use during the medical visit.

Herbal Medicine for Traumatic Brain Injury: A Systematic Review and Meta-Analysis of Randomized Controlled Trials and Limitations

Background: This systematic review aimed to evaluate the effectiveness (functional outcomes and clinical symptoms) and safety (incidence of adverse events) of herbal medicine (HM) as monotherapy or adjunctive therapy to conventional treatment (CT) for traumatic brain injury (TBI).

Methods: We comprehensively searched 14 databases from their inception until July 2019. Randomized controlled trials (RCTs) using HM as monotherapy or adjunctive therapy to treat TBI patients were included. The primary outcome was functional outcomes, consciousness state, morbidity, and mortality. Meta-analysis was performed to calculate a risk ratio (RR) or mean difference (MD) with 95% confidence intervals (CIs), when appropriate data were available. Methodological quality of RCTs and the strength of evidence were also assessed.

Results: Thirty-seven RCTs with 3,374 participants were included. According to meta-analysis, HM as a monotherapy (RR 1.29, 95% CI: 1.21–1.37) or an adjunctive therapy to CT (RR 1.21, 95% CI: 1.16–1.27) showed significantly better total effective rate based on clinical symptoms, compared to CT alone. Subgroup analysis showed that HM had significantly improved post-concussion syndrome, dizziness, headache, epilepsy, and mild TBI, but not traumatic brain edema, compared to CT. Moreover, HM combined with CT had significantly improved post-concussion syndrome, mental disorder, headache, epilepsy, and mild TBI-like symptoms, but not cognitive dysfunction and posttraumatic hydrocephalus, compared to CT alone. When HM was combined with CT, functional outcomes such as activities of daily living and neurological function were significantly better than in patients treated using CT alone. In terms of the incidence of adverse events, HM did not differ from either CT (RR 0.88, 95% CI: 0.33–2.30) or placebo (RR 2.29, 95% CI: 0.83–6.32). However, HM combined with CT showed better safety profile than CT alone (RR 0.64, 95% CI: 0.44–0.93). Most studies had a high risk of performance bias, and the quality of evidence was mostly rated “very low” to “moderate,” mostly because the included studies had a high risk of bias and imprecise quantitative synthesis results.

Conclusion: The current evidence suggests that there is insufficient evidence for recommending HM for TBI in clinical practice. Therefore, further larger, high-quality, rigorous RCTs should be conducted.

Efficacy and Safety of Wendan Decoction for Acute Brain Injury: A Randomized Controlled Study

Objectives: Despite the remarkable advances in critical care management of acute brain injury for the past 20 years, the prognoses remain poor. However, numerous reports indicate the efficacy of Traditional Chinese Medicine (TCM) therapy in stroke rehabilitation. This study aimed to determine the efficacy and safety of integrated TCM (Wendan decoction [WDD]) in patients with acute brain injury as a combination therapy in the early stages. Design: Prospective randomized controlled trial. Setting: Single-center study. Subjects: Sixty patients diagnosed with acute brain injury were randomly assigned to intervention and control groups, equally, and 41 patients completed the study. Interventions: All patients were treated by conventional neurologic intensive care. The 23 patients in the intervention group were administered with an integrated WDD in the early stages three times daily; combination treatment was initiated within 14 days and lasted >1 month. Outcome measures: Duration of ventilator use, intensive care unit stays, Glasgow Coma Scale (GCS) scores, motor response, the best muscle power, disability rating scale (DRS) scores, modified Rankin scale (mRS) scores, and the mortality rate for the first month. The other outcome measures were GCS scores, motor response, the best muscle power, DRS, mRS, and Barthel index (BI) scores 6 months later. Results: There was no mortality in the intervention group, but the rate was 39% in the control group for first month. Comparisons between groups showed significant differences (p < 0.05) in GCS, DRS, mRS, and BI scores, indicating improvements in the intervention group after 6 months. Conclusions: In the early stages of acute brain injury, combination treatment with WDD was found to be safe. Furthermore, this treatment may improve neurologic functional outcomes after 6 months.

Rhein and rhubarb similarly protect the blood-brain barrier after experimental traumatic brain injury via gp91phox subunit of NADPH oxidase/ROS/ERK/MMP-9 signaling pathway

Oxidative stress chiefly contributes to the disruption of the BBB following traumatic brain injury (TBI). The Chinese herbal medicine rhubarb is a promising antioxidant in treating TBI. Here we performed in vivo and in vitro experiments to determine whether rhubarb and its absorbed bioactive compound protected the BBB after TBI by increasing ZO-1 expression through inhibition of gp91phox subunit of NADPH oxidase/ROS/ERK/MMP-9 pathway. Rats were subjected to the controlled cortical impact (CCI) model, and primary rat cortical astrocytes were exposed to scratch-wound model. The liquid chromatography with tandem mass spectrometry method showed that rhein was the compound absorbed in the brains of CCI rats after rhubarb administration. The wet-dry weights and Evans blue measurements revealed that rhubarb and rhein ameliorated BBB damage and brain edema in CCI rats. Western blots showed that rhubarb and rhein downregulated GFAP in vitro. RT-PCR, immunohistochemistry, Western blot and dichlorodihydrofluorescein diacetate analysis indicated that rhubarb prevented activation of gp91phox subunit of NADPH oxidase induced ROS production, subsequently inhibited ERK/MMP-9 pathway in vivo and in vitro. Interestingly, rhein and rhubarb similarly protected the BBB by inhibiting this signaling cascade. The results provide a novel herbal medicine to protect BBB following TBI via an antioxidative molecular mechanism.

Advances in diagnosis, treatments, and molecular mechanistic studies of traumatic brain injury

Traumatic brain injury (TBI) is a main cause of death and disability around the world especially in soldiers, children, and young men. Since its clinical diagnosis and treatment cannot predict its prognosis, novel diagnostic techniques need to be developed, insight into its molecular mechanisms needs to be gleaned, and alternative and complementary medicine (ACM) approaches to its treatment need to be developed. This review summarizes the new diagnostic methods used in clinical practice, such as imaging of structural abnormalities after TBI and measurement of prognosis-related biomarkers. This review also describes the cellular mechanisms of traditional Chinese medicine in terms of intracellular signaling pathways, the extracellular microenvironment, and stem cells. This review concludes by describing experimental and clinical studies of the use of traditional Chinese medicine as a form of ACM to treat TBI. This review helps to understand advances in the field of TBI diagnosis and treatment.
