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.

NeuroDots: From Single-Target to Brain-Network Modulation: Why and What Is Needed?

OBJECTIVES: Current techniques in brain stimulation are still largely based on a phrenologic approach that a single brain target can treat a brain disorder. Nevertheless, meta-analyses of brain implants indicate an overall success rate of 50% improvement in 50% of patients, irrespective of the brain-related disorder. Thus, there is still a large margin for improvement. The goal of this manuscript is to 1) develop a general theoretical framework of brain functioning that is amenable to surgical neuromodulation, and 2) describe the engineering requirements of the next generation of implantable brain stimulators that follow from this theoretic model. MATERIALS AND METHODS: A neuroscience and engineering literature review was performed to develop a universal theoretical model of brain functioning and dysfunctioning amenable to surgical neuromodulation. RESULTS: Even though a single target can modulate an entire network, research in network science reveals that many brain disorders are the consequence of maladaptive interactions among multiple networks rather than a single network. Consequently, targeting the main connector hubs of those multiple interacting networks involved in a brain disorder is theoretically more beneficial. We, thus, envision next-generation network implants that will rely on distributed, multisite neuromodulation targeting correlated and anticorrelated interacting brain networks, juxtaposing alternative implant configurations, and finally providing solid recommendations for the realization of such implants. In doing so, this study pinpoints the potential shortcomings of other similar efforts in the field, which somehow fall short of the requirements. CONCLUSION: The concept of network stimulation holds great promise as a universal approach for treating neurologic and psychiatric disorders.

Maternal levels of care during pregnancy influence labor and delivery outcomes - present practices and future priorities.

Neonatal encephalopathy (NE) is a diagnosis that is usually unexpected. Though there are many risk factors for the condition and multiple theories as to its genesis, the majority of cases cannot be predicted prior to the occurrence of the clinical syndrome. Indeed, it is common for a pregnant person to have multiple risk factors and a completely healthy child. Conversely, people with seemingly no risk factors may go on to have a profoundly affected child. In this synopsis we review risk factors, potential mechanisms for encephalopathy, the complicated issue of choosing which morbidity to take on and how the maternal level of care may influence outcomes. The reader should be able to better understand the limitations of current testing and the profound levels of maternal intervention that have been undertaken to prevent or mitigate the rare, but devastating occurrence of NE. Further, we suggest candidate future approaches to prevent the occurrence, and decrease the severity of NE. Any future improvements in the NE syndrome cannot be achieved via obstetric intervention and management alone or conversely, by improvements in treatments offered post-birth. Multidisciplinary approaches that encompass prepregnancy health, pregnancy care, intrapartum management and postpartum care will be necessary.

Current research status and reflection on acupuncture treatment for brain disorders. / é’ˆç¸æ²»ç–—è„‘ç— çš„ç ”ç©¶çŽ°çŠ¶ä¸Žæ€è€ƒ.

Acupuncture has demonstrated positive efficacy in the treatment of brain disorders. However, significant challenges lie in integrating acupuncture with modern technologies, promoting its clinical application in treating brain disorders, elucidating the mechanisms underlying acupuncture's preventive and therapeutic effects on brain disorders, and accelerating the pace of translational development in acupuncture medicine. This paper briefly outlines the current research status, challenges, and potential future directions in acupuncture treatment for brain disorders, aiming to provide essential insights for the modernization and development of acupuncture in the treatment of brain disorders.

Understanding immune microenvironment alterations in the brain to improve the diagnosis and treatment of diverse brain diseases.

Abnormal inflammatory states in the brain are associated with a variety of brain diseases. The dynamic changes in the number and function of immune cells in cerebrospinal fluid (CSF) are advantageous for the early prediction and diagnosis of immune diseases affecting the brain. The aggregated factors and cells in inflamed CSF may represent candidate targets for therapy. The physiological barriers in the brain, such as the blood‒brain barrier (BBB), establish a stable environment for the distribution of resident immune cells. However, the underlying mechanism by which peripheral immune cells migrate into the brain and their role in maintaining immune homeostasis in CSF are still unclear. To advance our understanding of the causal link between brain diseases and immune cell status, we investigated the characteristics of immune cell changes in CSF and the molecular mechanisms involved in common brain diseases. Furthermore, we summarized the diagnostic and treatment methods for brain diseases in which immune cells and related cytokines in CSF are used as targets. Further investigations of the new immune cell subtypes and their contributions to the development of brain diseases are needed to improve diagnostic specificity and therapy.

Non-cirrhotic hyperammonaemic encephalopathy secondary to metastatic pancreatic neuroendocrine tumour treated with peptide receptor radio nucleotide therapy and transarterial chemoembolisation.

Neuroendocrine tumours (NETs) are rare cancers which often carry significant morbidity and mortality, frequently related to burden of liver metastases. Hyperammonaemia and subsequent hepatic encephalopathy carries a poor prognosis and has been described in these patients. We discuss a case of a woman in her 50s with hyperammonaemic encephalopathy and a new diagnosis of pancreatic NET with hepatic metastases. She presented with a reduced conscious state a few days post commencing chemotherapy. This was considered to have a multifactorial pathophysiology: the primary driver being large volume hepatic metastases and contributed by portosystemic microshunting, sepsis, severe weight loss and malnutrition. We describe how each of these exacerbating factors was addressed and highlight the effective multimodal treatment approach consisting of sequential transarterial chemoembolisation followed by peptide receptor radio nucleotide therapy, resulting in the resolution of hyperammonaemic encephalopathy and radiological partial metabolic response.

Establishing a regional registry for neonatal encephalopathy: impact on identification of gaps in practice.

BACKGROUND: Neonatal encephalopathy (NE) continues to be a significant risk for death and disability. To address this risk, regional guidelines were developed with the support of a malpractice insurance patient safety organization. A NE registry was also established to include 14 centers representing around 50% of deliveries in the state of Massachusetts. The aim of this study was to identify areas of variation in practice that could benefit from quality improvement projects. METHODS: This manuscript reports on the establishment of the registry and the primary findings to date. RESULTS: From 2018 to 2020, 502 newborns with NE were evaluated for Therapeutic Hypothermia (TH), of which 246 (49%) received TH, representing a mean of 2.91 per 1000 live births. The study reports on prenatal characteristics, delivery room resuscitation, TH eligibility screening, and post-natal management of newborns with NE who did and did not receive TH. CONCLUSIONS: The registry has allowed for the identification of areas of variation in clinical practices, which have guided ongoing quality improvement projects. The authors advocate for the establishment of local and regional registries to standardize and improve NE patient care. They have made the registry data collection tools freely available for other centers to replicate this work. IMPACT: Malpractice insurance companies can take an active role in supporting clinicians in establishing clinical practice guidelines and regional registries. Establishing a collaborative regional neonatal encephalopathy (NE) registry is feasible. Data Collection tools for a NE registry have been made publicly available to be adopted and replicated by other groups. Establishing a regional NE registry allowed for the identification of gaps in knowledge, variations in practice, and the opportunity to advance care through quality improvement projects.

Therapeutic plasma exchange in refractory Susac's syndrome: A brief report.

Susac's syndrome (SuS) is an autoimmune endotheliopathy that typically presents with the clinical triad of encephalopathy, hearing loss, and branch retinal artery occlusion. It has a wide range of possible presentations, and its pathogenesis remains uncertain. Fulminant and refractory cases are difficult to treat, and no standard treatment protocol has been established. However, therapeutic plasma exchange (TPE) has been described as an adjunctive therapy in several SuS cases. Herein we present a case of a 63-year-old male with debilitating encephalopathy and recent hearing and vision loss, who responded favorably to TPE. Given this and other published reports of plasma exchange therapy for SuS, treatment protocols should consider TPE in early stages of disease.

Application of in vivo brain imaging technology in the basic research of acupuncture-moxibustion for encephalopathy. / æ´»ä½“è„‘æˆåƒæŠ€æœ¯åœ¨é’ˆç¸è„‘ç— åŸºç¡€ç ”ç©¶ä¸­çš„åº”ç”¨.

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.

Troponin-T value as a prognostic marker in neonates diagnosed with neonatal encephalopathy and receiving hypothermia treatment.

OBJECTIVE: The aim of this study was to investigate the effect of Troponin-T levels on the prognosis of neonatal encephalopathy (NE). PATIENTS AND METHODS: The study included one hundred and eleven newborns diagnosed with NE and receiving hypothermia treatment. The cases were separated into 2 groups according to the SARNAT classification as Stage 2 or Stage 3. The groups were compared in respect of anthropometric characteristics, APGAR scores, and biochemical parameters. The cases were also separated into 3 groups according to the Troponin-T levels and were compared with respect to the clinical course. RESULTS: The serum Troponin-T (p=0.012), alanine aminotransferase (ALT) and aspartate aminotransferase (AST) (p<0.0001), and lactate levels (p=0.04) in the Sarnat Stage 3 group were statistically significantly higher than in the Sarnat stage 2 group. A significant positive correlation was determined between the Troponin-T level and the total duration of respiratory support (r=0.20, p=0.03). A significant positive correlation was determined between the ALT/AST ratio and the length of stay in hospital (r=0.29, p=0.001), duration of intubation (r=0.32, p=0.01), and total duration of respiratory support (r=0.36, p<0.001). A statistically significant difference was determined in mortality rates between the 3 subgroups of Troponin-T levels; Group 1: 2.8%, Group 2:5.4%, and Group 3: 15.8%. (p=0.04, χ²=4.74). A cut-off value of 164 ng/L for Troponin-T was determined to predict mortality with 77% sensitivity and 67% specificity (AUC=0.73, p=0.023). When the groups were compared according to Troponin-T level, a statistically significant difference was determined in respect of length of stay in hospital (p=0.03, χ²=6.95) and total duration of oxygen support (p=0.01, χ²=9.12). CONCLUSIONS: The serum Troponin-T level can be evaluated as a prognostic marker in cases followed up with a diagnosis of NE and receiving hypothermia treatment. There is a need for further prospective studies with larger samples on this subject.

Circular RNAs: Diagnostic and Therapeutic Perspectives in CNS Diseases.

Circular RNAs (circRNAs) are a class of regulatory non-coding RNAs characterized by the presence of covalently closed ends. A growing body of evidence suggests that circRNAs play important roles in physiology and pathology. In particular, accumulating data on circRNA functions in various central nervous system (CNS) diseases and their correlations indicate that circRNAs are critical contributors to the onset and development of brain disorders. In this review, we focus on the regulatory and functional roles of circRNAs in CNS diseases, highlighting their diagnostic and therapeutic potential, with the aim of providing new insights into CNS diseases.

Clinical presentations and treatment outcomes of Hashimoto encephalopathy at Siriraj Hospital - Thailand's largest national tertiary referral center.

BACKGROUND: Hashimoto encephalopathy has multiple clinical presentations, and other than the presence of thyroid antibody, laboratory and imaging investigations are all non-specific. Data specific to the clinical presentations and treatment outcomes of patients with Hashimoto encephalopathy in Thailand remain scarce. OBJECTIVES: To retrospectively investigate the clinical presentations and treatment outcomes of patients with Hashimoto encephalopathy at Siriraj Hospital. METHODS: Patients who presented with acute encephalopathy at our center during July 2012-March 2017 were evaluated for eligibility. The inclusion criteria were positive anti-thyroperoxidase (anti-TPO) or anti-thyroglobulin (anti-Tg) in serum with negative neuronal antibody in serum or cerebral spinal fluid (CSF). Clinical presentations, symptom duration, laboratory results of thyroid status and thyroid autoantibody, CSF study, and clinical outcomes were collected. RESULTS: Of the 204 patients who presented with encephalopathy, 31 (15.2%) were positive for the anti-TPO or anti-Tg antibody. Of those, 13 patients met the diagnostic criteria for Hashimoto encephalopathy. Clinical presentations included cognitive impairment (76.9%), clouding of consciousness (46.2%), and behavior change (30.8%). The neuropsychiatric presentations were visual hallucination (30.8%), auditory hallucination (15.4%), delusion (7.7%), and mood disturbance (23.1%). Other clinical presentations included seizure (38.5%), abnormal movement (23.1%), sleep disturbance (38.5%), ataxia (46.2%), stroke-like episode (15.4%), and fever (15.4%). Most patients (76.9%) had onset within < 3 months. Regarding outcomes, 1 patient who did not receive corticosteroid died from status epilepticus and septic shock. Among the 12 patients who received corticosteroid, 9 (75%) had marked improvement, 1 (8.3%) had slight improvement, and 2 (16.6%) had no clinical improvement. Seven patients (53.9%) had normal thyroid function, 4 patients (30.8%) had subclinical hypothyroidism, and 2 patients (15.4%) had subclinical hyperthyroidism. CONCLUSIONS: The results of this study revealed cognitive impairment, neuropsychiatric symptoms, seizure, ataxia, and sleep disturbance to be common manifestations of Hashimoto encephalopathy. This condition should always be considered in individuals with subacute onset of unexplained cognitive impairment or cerebellar ataxia. Laboratory and neuroimaging investigations were all found to be nonspecific in Hashimoto encephalopathy. Most patients responded well to treatment, so clinical suspicion and early diagnosis and treatment will lead to improved patient outcomes.

Preventive effect of peptides derived from fermented milk on chronic stress-induced brain damage and intestinal dysfunction in mice.

This study investigated the preventive effects of peptides derived from milk fermented with the probiotic strain Lactobacillus gasseri 505 (505) against stress-related brain damage and anxiety-like behavior. The peptides MKPWIQPKTKVIPYVRYL (Pep14) and VYQHQKAMKPWIQPKTKVIPYVRYL (Pep21), which exhibit high antioxidant and anti-inflammatory activities, were administered to stressed mice. The results showed that the stress mechanism in the gut-brain axis was regulated by pretreatment with both peptides, leading to inhibition of neurodevelopment and neuroinflammation through the hypothalamic-pituitary-adrenal (HPA) axis, based on the expression of related mRNA and proteins. The expression of colonic inflammation-related mRNA and proteins was also reduced. Moreover, anxiety-like behavior was significantly reduced in mice treated with Pep14 and Pep21. These results indicate that the bioactive peptides Pep14 and Pep21, derived from milk fermented with 505, may prevent stress-induced brain damage and anxiety-like behavior via regulation of the HPA axis.
