Disease spectrum and strategy of acupuncture and moxibustion in treatment of encephalopathy. / è„‘ç— é’ˆç¸æ²»ç–—çš„ç— è°±ä¸Žç­–ç•¥æ€è€ƒ.

The paper presents the summary of the spectrum of encephalopathy treated with acupuncture and moxibustion and the analysis on the existing questions in its clinical research, and proposes the potential strategies on treatment of encephalopathy with acupuncture and moxibustion. The spectrum of encephalopathy includes 23 diseases of central nervous system (superspinal center) and 33 kinds of mental and behavioral disorders. There are three problems in clinical research of acupuncture and moxibustion for encephalopathy, i.e. lack of high-quality clinical evidences, inadequate support from theoretic study of TCM and limited study on the rules of treatment. Hence, the author proposes five strategies on the treatment of encephalopathy with acupuncture and moxibustion, i.e. ① stimulating the peripheral nerve trunk associated with brain dysfunction, triggering the interaction between peripheral and central nerves and emphasizing the autonomic rehabilitation training to promote the reorganization of brain function; ② improving the cerebral circulation and metabolism by stimulating the trigeminal nerve and sphenopalatine ganglion; ③ stimulating the sites with high-dense distribution of peripheral nerve endings and the large projection area in the somatosensory region of the brain to induce strong brain responses, which may adjust the abnormal operation of the default mode network in the resting state; ④ stimulating the vagus nerve to improve the mood, suppressing the abnormal firing of brain neurons and stimulating the sites with the stellate ganglion distributed to modulate the hypothalamic function; ⑤ delivering the therapeutic regimens in association with the specific conditions and symptoms, and the classification of the physical signs on the base of the treatment of encephalopathy.

Acupuncture-moxibustion is remarkably effective on encephalopathy, but its mechanism is unclear. With the continuous development of imaging technology, the in vivo brain imaging technology has been used increasingly in life science research and it also becomes a more effective tool for the basic research of acupuncture-moxibustion in treatment of encephalopathy. The paper summarizes the application of its technology in the basic research of acupuncture-moxibustion for encephalopathy and the characteristics of imaging, as well as the advantages and shortcomings. It is anticipated that the references may be provided for the basic research of acupuncture-moxibustion in treatment of encephalopathy and be conductive to the modernization of acupuncture-moxibustion.

Acupuncture for brain diseases: Conception, application, and exploration.

The brain is probably the most complex organ in the human body. It has been the hot spot and direction of brain science research all over the world to deeply study the pathogenesis of various kinds of brain diseases and find effective treatment methods. Acupuncture is a nonpharmacological therapy of traditional Chinese medicine originating from ancient clinical practice. The research on the treatment of brain diseases by acupuncture has been constantly enriched and updated with the promotion of interdisciplinary research. In order to account for the current achievements in the field of acupuncture for brain diseases, this article reviews it in terms of conception, application, and exploration. Based on the literature review, we found that in the past decades, acupuncture has received widespread attention worldwide and many literatures have reported the clinical efficacy and underlying mechanisms of acupuncture in the treatment of brain diseases. Presently, the conception, application, and exploration of acupuncture in the treatment of brain diseases have evolved from empirical medicine to evidence-based medicine and precision medicine, and are experiencing a deeper understanding of the information about acupuncture regulating the brain function based on interdisciplinary research.

Effect of hyperbaric oxygen on symptoms of dementia in patients with delayed encephalopathy after acute carbon monoxide poisoning. / é«˜åŽ‹æ°§å¯¹æ€¥æ€§ä¸€æ°§åŒ–ç¢³ä¸­æ¯’è¿Ÿå‘æ€§è„‘ç— æ‚£è€ ç—´å‘†ç—‡çŠ¶çš„å½±å“ï¼ˆè‹±æ–‡ï¼‰.

OBJECTIVES: Delayed encephalopathy after acute carbon monoxide poisoning (DEACMP) is the most severe complication of carbon monoxide poisoning, which seriously endangers patients' quality of life. This study aims to investigate the efficacy of hyperbaric oxygen (HBO2) on improving dementia symptoms in patients with DEACMP. METHODS: A retrospective analysis was performed on DEACMP patients, who visited Xiangya Hospital, Central South University from June 2014 to June 2020. Among them, patients who received conventional drug treatment combined with HBO2 treatment were included in an HBO2 group, while those who only received conventional drug treatment were included in a control group. HBO2 was administered once daily. Patients in the HBO2 group received 6 courses of treatment, with each course consisting of 10 sessions. The Hasegawa Dementia Scale (HDS) was used to diagnose dementia, and the Clinical Dementia Rating (CDR) was used to grade the severity of dementia for DEACMP. The Alzheimer's Disease Assessment Scale-Cognitive Section (ADAS-Cog), the Functional Activities Questionnaire (FAQ), the Neuropsychiatric Inventory (NPI), and the Clinician's Interview-Based Impression of Change-Plus Caregiver Input (CIBIC-Plus) were performed to assess cognitive function, ability to perform activities of daily living (ADL), behavioral and psychological symptoms, and overall function. The study further analyzed the results of objective examinations related to patients' dementia symptoms, including magnetic resonance imaging detection of white matter lesions and abnormal electroencephalogram (EEG). The changes of the above indicators before and after treatment, as well as the differences between the 2 groups after treatment were compared. RESULTS: There was no significant difference in the HDS score and CDR grading between the 2 groups before treatment (both P>0.05). After treatment, the score of ADAS-Cog, FAQ, NPI, and CIBIC Plus grading of the 2 groups were significantly improved, and the improvement of the above indicators in the HBO2 group was greater than that in the control group (all P<0.05). The effective rate of the HBO2 group in treating DEACMP was significantly higher than that of the control group (89.47% vs 65.87%, P<0.05). The objective examination results (white matter lesions and abnormal EEG) showed that the recovery of patients in the HBO2 group was better than that in the control group. CONCLUSIONS: Hyperbaric oxygen can significantly relieve the symptoms of dementia in patients with DEACMP.

Neuromodulation in 2035: The Neurology Future Forecasting Series.

Neuromodulation devices are approved in the United States for the treatment of movement disorders, epilepsy, pain, and depression, and are used off-label for other neurologic indications. By 2035, advances in our understanding of neuroanatomical networks and in the mechanism of action of stimulation, coupled with developments in material science, miniaturization, energy storage, and delivery, will expand the use of neuromodulation devices. Neuromodulation approaches are flexible and modifiable. Stimulation can be targeted to a dysfunctional brain focus, region, or network, and can be delivered as a single treatment, continuously, according to a duty cycle, or in response to physiologic changes. Programming can be titrated and modified based on the clinical response or a physiologic biomarker. In addition to keeping pace with clinical and technological developments, neurologists in 2035 will need to navigate complex ethical and economic considerations to ensure access to neuromodulation technology for a rapidly expanding population of patients. This article provides an overview of systems in use today and those that are anticipated and highlights the opportunities and challenges for the future, some of which are technical, but most of which will be addressed by learning about brain networks, and from rapidly growing experience with neuromodulation devices.

Brain stem and spinal cord demyelination due to acute carbon monoxide poisoning.

Demyelination throughout the brain stem and spinal cord caused by acute carbon monoxide (CO) poisoning has not been previously reported. Magnetic resonance imaging (MRI) has revealed that acute CO poisoning primarily affects the subcortical white matter of the bilateral cerebral hemispheres and basal ganglia. Here we report the case of a patient with delayed neuropsychological sequelae (DNS) due to acute CO poisoning. A 28-year-old man was admitted to our department following a suicide attempt by acute CO poisoning. After a six-month pseudo-recovery period, he was diagnosed with DNS, with MRI evidence of demyelinating change of the bilateral cerebral peduncles. Demyelination was identified throughout the brain stem, expanding from the bilateral cerebral peduncles to the medulla oblongata, occurring approximately six months after poisoning. One and a half years after acute CO poisoning, demyelination of the cervical and thoracic spine was observed, most notable in the lateral and posterior cords. It is evident that previously published research on this topic is extremely limited. Perhaps in severe cases of acute CO poisoning the fatality rate is higher, leading to fewer surviving cases for possible study. This may be because a more severe case of acute CO poisoning would result in the higher likelihood of secondary demyelination. This research indicates that clinicians should be aware of the risk of secondary demyelination and take increased precautions such as vitamin B supplementation and administration of low-dose corticosteroids for an extended period of time in order to reduce the extent and severity of demyelination.

[Clinical effects of medical ozone autologous blood transfusion combined with Xingnaojing in the treatment of septic encephalopathy in burns].

Objective: To investigate the clinical effects of medical ozone autologous blood transfusion combined with Xingnaojing in the treatment of septic encephalopathy in burns. Methods: The retrospective cohort study was conducted. From August 2015 to May 2019, 90 patients with burn septic encephalopathy and conforming to the inclusion criteria were admitted to Zhengzhou First People's Hospital. Forty-six patients (25 males and 21 females, aged (35±4) years ) treated with Xingnaojing were included in Xingnaojing alone group, and forty-four patients (20 males and 24 females, aged (34±5) years) treated with medical ozone autologous blood transfusion combined with Xingnaojing were included in ozone autologous blood transfusion+Xingnaojing group. Heart rate, body temperature, mean arterial pressure, acute physiology and chronic health evaluation Ⅱ(APACHEⅡ) score and Glasgow coma score (GCS) of patients in 2 groups were recorded before treatment and on 7 d after treatment. The blood-brain barrier injury markers including occludin, nitric oxide synthase (NOS), neuron-specific enolase (NSE), central nervous system specific protein S100ß, glial fibrillar acidic protein (GFAP), and excitatory amino acid (EAA) in serum of patients in 2 groups were detected before treatment and on 1, 3, and 7 d after treatment. Computer tomography perfusion imaging for brain was performed in patients of 2 groups to calculate the region of interest cerebral blood flow (rCBF), region of interest blood volume (rCBV), and region of interest mean transit time (rMTT) before treatment and on 1, 3, and 7 d after treatment. Data were statistically analyzed with chi-square test, analysis of variance for repeated measurement, independent sample t test, and Bonferroni correction. Results: On 7 d after treatment, heart rate, body temperature, and mean arterial pressure of patients in 2 groups were decreased compared with those before treatment, heart rate of patients in ozone autologous blood transfusion+Xingnaojing group was obviously higher than that in Xingnaojing alone group (t=2.886, P<0.01), body temperature of patients in ozone autologous blood transfusion+Xingnaojing group was obviously lower than that in Xingnaojing alone group (t=5.020, P<0.01), and mean arterial pressure of patients in 2 groups were close (t=0.472, P>0.05). On 7 d after treatment, APACHEⅡ score of patients in ozone autologous blood transfusion+Xingnaojing group was obviously lower than that in Xingnaojing alone group (t=3.797, P<0.01), and GCS of patients in ozone autologous blood transfusion+Xingnaojing group was obviously higher than that in Xingnaojing alone group (t=4.934, P<0.01). On 3 and 7 d after treatment, the levels of occludin, NOS, NSE, S100ß, GFAP, and EAA in serum of patients in ozone autologous blood transfusion+Xingnaojing group were significantly lower than those in Xingnaojing alone group (t=2.100, 2.090, 2.691, 2.013, 2.474, 2.635, 2.225, 4.011, 3.150, 2.691, 3.145, 2.781, P<0.05 or P<0.01). On 1, 3, and 7 d after treatment, rCBF and rCBV of patients in ozone autologous blood transfusion+Xingnaojing group were significantly increased compared with those in Xingnaojing alone group (t=3.127, 3.244, 3.883, 7.274, 3.661, 2.777, P<0.01). On 7 d after treatment, rMTT of patients in ozone autologous blood transfusion+Xingnaojing group was (3.02±0.57) s, which was significantly lower than (3.11±1.20) s in Xingnaojing alone group (t=2.409, P<0.05). Conclusions: Transfusion of medical ozone autologous blood combined with Xingnaojing therapy can effectively relieve brain injury and improve cerebral blood perfusion in patients with burn septic encephalopathy, which is with safety and credibility.

Umbilical cord-derived MSC and hyperbaric oxygen therapy effectively protected the brain in rat after acute intracerebral haemorrhage.

This study tested the hypothesis that combined therapy with human umbilical cord-derived mesenchymal stem cells (HUCDMSCs) and hyperbaric oxygen (HBO) was superior to either one on preserving neurological function and reducing brain haemorrhagic volume (BHV) in rat after acute intracerebral haemorrhage (ICH) induced by intracranial injection of collagenase. Adult male SD rats (n = 30) were equally divided into group 1 (sham-operated control), group 2 (ICH), group 3 (ICH +HUCDMSCs/1.2 × 106 cells/intravenous injection at 3h and days 1 and 2 after ICH), group 4 (ICH +HBO/at 3 hours and days 1 and 2 after ICH) and group 5 (ICH +HUCDMSCs-HBO), and killed by day 28 after ICH. By day 1, the neurological function was significantly impaired in groups 2-5 than in group 1 (P < .001), but it did not differ among groups 2 to 5. By days 7, 14 and 28, the integrity of neurological function was highest in group 1, lowest in group 2 and significantly progressively improved from groups 3 to 5 (all P < .001). By day 28, the BHV was lowest in group 1, highest in group 2 and significantly lower in group 5 than in groups 3/4 (all P < .0001). The protein expressions of inflammation (HMGB1/TLR-2/TLR-4/MyD88/TRAF6/p-NF-κB/IFN-γ/IL-1ß/TNF-α), oxidative stress/autophagy (NOX-1/NOX-2/oxidized protein/ratio of LC3B-II/LC3B-I) and apoptosis (cleaved-capspase3/PARP), and cellular expressions of inflammation (CD14+, F4/80+) in brain tissues exhibited an identical pattern, whereas cellular levels of angiogenesis (CD31+/vWF+/small-vessel number) and number of neurons (NeuN+) exhibited an opposite pattern of BHV among the groups (all P < .0001). These results indicate that combined HUCDMSC-HBO therapy offered better outcomes after rat ICH.

Understanding the heart-brain axis response in COVID-19 patients: A suggestive perspective for therapeutic development.

In-depth characterization of heart-brain communication in critically ill patients with severe acute respiratory failure is attracting significant interest in the COronaVIrus Disease 19 (COVID-19) pandemic era during intensive care unit (ICU) stay and after ICU or hospital discharge. Emerging research has provided new insights into pathogenic role of the deregulation of the heart-brain axis (HBA), a bidirectional flow of information, in leading to severe multiorgan disease syndrome (MODS) in patients with confirmed infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Noteworthy, HBA dysfunction may worsen the outcome of the COVID-19 patients. In this review, we discuss the critical role HBA plays in both promoting and limiting MODS in COVID-19. We also highlight the role of HBA as new target for novel therapeutic strategies in COVID-19 in order to open new translational frontiers of care. This is a translational perspective from the Italian Society of Cardiovascular Researches.

[Severe encephalopathy and vitamin B12 deficiency: reversibility after nutritional therapy]. / Encefalopatía grave y deficiencia de vitamina B12: reversibilidad tras la terapia nutricional.

INTRODUCTION: Introduction: the vitamin cobalamin is essential for a proper functioning of the CNS, hematopoiesis, and DNA synthesis. Its deficiency is frequently secondary to pernicious anemia or strict vegetarian diets. Case report: an 18-month-old male infant presented with a decreased level of consciousness and movement disorder (tremor and choreiform movements) of several hours' standing. He had a history of delayed acquisition of motor milestones (not standing, monosyllabic language), and progressive loss of these over the last few weeks (head support and sitting). He had been breastfed from birth. His family has a vegetarian diet. In neuroimages, cranial CT and MRI scans showed generalized supratentorial atrophy involving both matters and the basal ganglia. Treatment was started with intramuscular vitamin B12, which increased its levels. Subsequently, the patient was subjected to dietary diversification and oral cyanocobalamin, with clinical normalization after 6 months and radiological normalization after 7 months. Conclusions: we emphasize the importance of vitamin B12 supplementation during pregnancy and lactation in vegetarina mothers and their infants.

INTRODUCCIÓN: Introducción: la vitamina cobalamina es esencial para el buen funcionamiento del SNC, la hematopoyesis y la síntesis de ADN. Su déficit es frecuentemente secundario a la anemia perniciosa o a las dietas vegetarianas estrictas. Caso clínico: lactante varón de 18 meses con disminución del nivel de conciencia y trastorno del movimiento (temblor y movimientos coreiformes) de horas de duración. Como antecedentes, presenta retraso de adquisición de hitos motores (no bipedestación, lenguaje monosilábico) y pérdida progresiva de los mismos en lúltimas semanas (sostén cefálico y sedestación). Alimentado mediante lactancia materna desde el nacimiento. La familia sigue una alimentación vegetariana. En las pruebas de neuroimagen, la TC y la RM craneales muestran atrofia supratentorial generalizada de ambas sustancias y de los ganglios basales. Se inicia tratamiento con vitamina B12 intramuscular, aumentando sus niveles. Posteriormente se procede a la diversificación alimentaria y la administración de cianocobalamina oral, con normalización clínica al cabo de 6 meses y radiológica al cabo de 7 meses. Conclusiones: recalcamos la importancia de la suplementación con B12 durante el embarazo y lactancia tanto en la mujer como en el lactante.

[The mechanism of hyperbaric oxygen regulating HMGB1 in the prevention and treatment of encephalopathy after acute CO poisoning].

Objective: To study the expression of high mobility group protein 1 (HMGB1) in the brain of rats after hyperbaric oxygen (HBO) treatment of acute carbon monoxide poisoning (DEACMP) , and to explore the mechanism of HBO in the prevention and treatment of DEACMP pathological process by regulating HMGB1. Methods: 108 SD rats were randomly divided into control group (NC group) and co group (CO group) . HBO treatment group (HBO group) , 48 rats in each group. Co group and HBO group were used to establish CO poisoning model, HBO group were treated with hyperbaric oxygen once a day. Water maze test was used to detect and analyze the memory retention ability of three groups of rats in 3 d, 7 d, 14 d. ELISA was used to detect the plasma concentration of HMGB1、IL-6、TNF-α in three groups of rats on the 1 d, 3 d, 7 d, 14 d, 21 d Concentration. Western blotting was used to detect the expression of HMGB1 and Caspase-3 in the brain of the three groups on the 1 d, 3 d, 7 d, 14 d, 21 d. TUNEL staining was used to detect the apoptosis of hippocampal neurons in the three groups. Results: Compared with NC group, the average escape latency of rats in CO group and HBO group was significantly prolonged, and the activity time of platform quadrant in CO group was significantly shortened on 14 d and 21 d (P<0.05) ; compared with CO group, the average escape latency of HBO group on 7 d, 14 d and 21 d was significantly shortened (P<0.05) . Compared with NC group, plasma HMGB1 in CO group and HBO group were significantly increased (P<0.05) ; after 3 days, HBO group was significantly lower than co group, the difference was statistically significant (P<0.05) . The levels of IL-6 and TNF-α in HBO group and co group increased rapidly and then decreased gradually. The increased levels of IL-6 and TNF-α in HBO group were significantly lower than those in CO group (P<0.05) . Compared with NC group, the expression of HMGB1 and Caspase-3 in CO group was significantly increased on 3 d, 7 d and 14 d (P<0.05) ; the expression of HMGB1 and Caspase-3 in HBO group was significantly increased on 3 d, 7 d, 14 d and 21 d (P<0.05) ; compared with CO group, the expression of HMGB1 and Caspase-3 in HBO group decreased significantly on 3 d, 7 d, 14 d and 21 d (P<0.05) . The apoptotic index of nerve cells in CO group began to increase at 3 days, which was significantly different from that of NC group (P<0.05) , and the difference was still statistically significant on 21 d (P<0.05) ; the apoptotic index of nerve cells in HBO group was slightly increased, but there was no significant difference compared with NC group (P>0.05) , and the apoptotic index of 3 d, 7 d, 14 d and 21 d in HBO group was significantly lower than that in CO group (P<0.05) . Conclusion: acute CO poisoning can induce the release of HMGB1 and a variety of inflammatory factors. HMGB1 can promote the apoptosis of nerve cells after acute CO poisoning by up regulating the expression of caspase-3 protein, and participate in the pathological process of DEACMP. HBO can down regulate the expression of HMGB1, IL-6, TNF-α and caspase-3 protein, inhibit the apoptosis of nerve cells, and play a protective role on nerve cells.

The Importance of Marine Omega-3s for Brain Development and the Prevention and Treatment of Behavior, Mood, and Other Brain Disorders.

Most of the global population is deficient in long-chain marine omega-3s. In particular, docosahexaenoic acid (DHA), a long-chain omega-3 fatty acid, is important for brain and eye development. Additionally, DHA plays a significant role in mental health throughout early childhood and even into adulthood. In the brain, DHA is important for cellular membrane fluidity, function and neurotransmitter release. Evidence indicates that a low intake of marine omega-3s increases the risk for numerous mental health issues, including Attention Deficit Hyperactivity Disorder (ADHD), autism, bipolar disorder, depression and suicidal ideation. Studies giving supplemental marine omega-3s have shown promise for improving numerous mental health conditions. This paper will review the evidence surrounding marine omega-3s and mental health conditions.

Perinatal encephalopathy, the syndrome of intracranial hypertension and associated diagnostic labels in the Commonwealth of Independent States: a systematic review.

BACKGROUND: The WHO reports excessive rates of ill-defined neurological diagnoses and ineffective and potentially harmful drug treatments in children in the Commonwealth of Independent States (CIS). Collectively termed perinatal encephalopathy and the syndrome of intracranial hypertension (PE-SIH), these diagnoses are important contributors to perceived childhood morbidity and disability in the CIS. A systematic compilation of information on PE-SIH is lacking. METHODS: We systematically reviewed publications between 1970 and 2020 on PE-SIH in Azerbaijani, English, Russian and Ukrainian languages and summarised information on PE-SIH. RESULTS: We identified 30 publications (70% in Russian) published 1976-2017. The diagnosis of PE-SIH was either based on unreported criteria (67% of reports), non-specific clinical features of typically developing children or those with common developmental disorders (20% of reports) or cranial ultrasound (13% of reports). The reported proportion of children with PE-SIH in the study samples ranged from 31% to 99%. There were few published studies on reassessments of children diagnosed with PE-SIH, and these did not confirm neurological disease in the majority of children. Treatments included multiple unlicenced drugs without established effectiveness and with potential unwanted effects. CONCLUSION: This review suggests that PE-SIH is a medical diagnostic label that is used in numerous children without substantive associated disease. The diagnosis and treatment of PE-SIH is a multidimensional, iatrogenic, clinical and public health problem in the CIS. With increasing use of evidence-based medicine guidelines in the region, it is hoped that PE-SIH will gradually disappear, but actions to accelerate this change are nevertheless needed.

[Assessment of efficacy of acupuncture combined with hyperbaric oxygen therapy for patients with delayed encephalopathy of CO intoxication by magnetic resonance voxel incoherent motion imaging].

OBJECTIVE: To observe the effect of acupuncture plus hyperbaric oxygen (HBO) on cerebral blood perfusion in patients with delayed encephalopathy after carbon monoxide poisoning (DEACMP). METHODS: Twenty-eight patients with DEACMP were randomly divided into acupuncture group (n=14 cases) and control group (n=14 cases). Patients of the acupuncture group were treated by using "Xingnao Kaiqiao" needling technique (specific set of acupuncture points as Yintang ï¼»EX-HN3ï¼½, Shangxing ï¼»GV23ï¼½, Baihui ï¼»GV20ï¼½, Sishenchong ï¼»EX-HN1ï¼½, Fengchi ï¼»GB20ï¼½, Taichong ï¼»LR3ï¼½, etc., and strong stimulation) combined with HBO in an air pressurized tank, and those of the control group treated by simple HBO. The treatment was conducted once a day, 5 days a week for 6 weeks. All the patients underwent head routine magnetic resonance imaging (MRI) and intravoxel incoherent motion imaging(IVIM) scan before and after the treatment. The values of pseudo-diffusion coefficient D (D*) and perfusion fraction (f) of the bilateral semi-oval centers were measured by using MITK software package to calculate the ave-rage fD* value (f×D*). The Barthel index (BI) score was used to assess the patients' daily living ability, and the correlation between parameter values was evaluated by Pearson method. RESULTS: After the treatment, the values of f, fD* and BI scores were significantly increased in both acupuncture group and control groups (P<0.05). The values of the 3 indexes were significantly higher in the acupuncture group than those in the control group (P<0.05). The values of f and fD* were positively correlated with BI score (P<0.05), with the correlation coefficients being 0.822, 0.636 and 0.601, respectively between the fD* and f, BI and f, and BI and fD*. CONCLUSION: Acupuncture combined with HBO can significantly improve the low-perfusion of bilate-ral semi-oval center and daily living ability in patients with DEACMP, being significantly superior to simple HBO therapy in the curative effect.

Baseline resilience and depression symptoms predict trajectory of depression in dyads of patients and their informal caregivers following discharge from the Neuro-ICU.

OBJECTIVE: To explore the impact of resiliency factors on the longitudinal trajectory of depressive symptoms in patients admitted to the Neuroscience Intensive Care Unit (Neuro-ICU) and their family caregivers. MATERIALS AND METHODS: Patients (N = 102) and family caregivers (N = 103) completed self-report assessments of depressive symptoms (depression subscale of the Hospital Anxiety and Depression Scale; HADS-D) and resiliency factors (i.e., mindfulness and coping) during Neuro-ICU hospitalization. The HADS-D was administered again at 3 and 6 months after discharge. The Actor-Partner Interdependence Model (APIM) was used to assess patient-caregiver interdependence. RESULTS: Baseline rates of clinically significant depressive symptoms were high among patients (23%) and caregivers (19%), and remained elevated through 6-months. Higher depressive symptoms predicted higher levels of symptoms at the subsequent timepoint (ps < 0.05). Higher baseline mindfulness and coping were associated with lower levels of depressive symptoms at all timepoints (ps < 0.001). APIM analysis showed that one's own higher baseline mindfulness was associated with concurrent levels of depressive symptoms in a partner (p < 0.05). CONCLUSIONS: Depressive symptoms in Neuro-ICU patient-caregiver dyads are high through 6 months. Mindfulness is protective against depressive symptoms and interdependent between patients and caregivers. Early, dyadic, mindfulness-based interventions may prevent the development of chronic depression in both patients and caregivers.

Tryptophan Metabolism and Related Pathways in Psychoneuroimmunology: The Impact of Nutrition and Lifestyle.

In the past, accelerated tryptophan breakdown was considered to be a feature of clinical conditions, such as infection, inflammation, and malignant disease. More recently, however, the focus has changed to include the additional modulation of tryptophan metabolism by changes in nutrition and microbiota composition. The regulation of tryptophan concentration is critical for the maintenance of systemic homeostasis because it integrates essential pathways involved in nutrient sensing, metabolic stress response, and immunity. In addition to tryptophan being important as a precursor for the synthesis of the neurotransmitter serotonin, several catabolites along the kynurenine axis are neuroactive. This emphasizes the importance of the immunometabolic fate of this amino acid for processes relevant to neuropsychiatric symptoms. In humans, besides hepatic catabolism, there is usually a strong relationship between immune activation-associated tryptophan breakdown and increased levels of biomarkers, such as neopterin, which has particular relevance for both acute and chronic diseases. A shift towards neopterin synthesis during oxidative stress may indicate a corresponding decrease in tetrahydrobiopterin, a cofactor of several mono-oxygenases, providing a further link between tryptophan metabolism and serotonergic and catecholaminergic neurotransmission. The psychoneuroimmunological consequences of tryptophan metabolism and the susceptibility of this pathway to modulation by a variety of nutritional and lifestyle-related factors have important implications for the development of both diagnostic and treatment options.

[Brain science promotes the development of acupuncture in treating brain diseases].

Brain science is the "ultimate territory" for human beings to understand the nature. In the present paper, the authors introduce the current state of brain science research projects in the USA, European countries, Japan and China. In recent years, with the continuous innovations of technologies in brain imaging, biosensors, human-computer interaction and big data, the brain science has become an important frontier field with interdisciplinarity and a focus of science and technology strategies in various countries. As a scientific and technological resource with original advantages in China, traditional Chinese medicine (TCM) is abundant in knowledge of brain, almost covering all kinds of encephalopathy in modern medicine. At present, TCM is increasingly becoming an effective tool to conquer mental and nervous diseases. With the intersection and penetration of multi-disciplines, an increasing close association between the traditional theory of TCM about prevention and treatment of encephalopathy and modern basic biological research appears, and new ideas, new technologies and new achievements have constantly been coming out, particularly in the field of acupuncture medicine. In the present historical juncture when the development of science and technology in China is changing from the "follower" to the "parallel runner", even the "top runner" in some fields, the progress of brain science research in TCM will make enormous contributions to explore brain disease and exploit cutting-edge technologies of TCM, as well as accelerate the modernization of TCM.

Management of delayed encephalopathy after CO poisoning: An evidence-based narrative review.

BACKGROUND: Approximately 10% to 30% patients develop delayed encephalopathy after acute CO poisoning (DEACMP). No specific treatment is available and poor prognosis is a characteristic of this disease. We aimed to evaluate the efficacy and safety of all therapies that have been tried in randomized controlled trial (RCT) for DEACMP. METHODS: We conducted a systematic search of the Cochrane, Embase, PubMed, and Web of Science databases. RESULTS: Overall, 4 RCTs were identified in our study. Both hyperbaric oxygen (HBO) and mesenchymal stem cell (MSC) transplantation were effective in DEACMP, and MSC seemed to be superior to HBO. The addition of dexamethasone, N-butylphthalide, or XingZhi-YiNao granules into HBO, or butylphthalide into MSC could achieve better neurological recovery in DEACMP patients but did not significantly increase the incidence of adverse events. CONCLUSION: Several therapies have shown positive results in treating DEACMP and need to be proven by further studies.
