Standardized Lycium chinense fruit extract enhances attention and cognitive function in healthy young people by a double-blind, randomized, placebo-controlled, crossover trial.

BACKGROUND: Lycium chinense fruit (LCF) is widely distributed in East Asia that has been used traditionally for antiaging purposes. This study was performed to examine the effects of LCF on attention and cognitive function in healthy young people. MATERIALS AND METHODS: An 11-week, double-blind, randomized, placebo-controlled, crossover trial of 74 patients was conducted and its data were collected on Kyung-Hee University Korean Medical Hospital, Seoul, Korea. In crossover treatment, LCF or placebo was administered three times a day, total 3600 mg as two capsules of 600 mg once for 4 weeks with 3-week washout each. The computerized neurocognitive function test (CNT), the Korean version of the attention-deficit/hyperactivity disorder rating scale-IV, the clinical global impression rating scale, and the Frankfurt attention inventory (FAIR) for two groups were conducted 0 week before and 4 week, 11 week after the experiment, and significant mean changes of these tests for within group or two groups were measured by paired t-test or unpaired t-test. RESULTS: The administration of LCF or placebo crossover for 8 weeks in healthy young people presented significant improvement in the verbal learning test, digit span forward test, digit span backward test, auditory continuous performance task of CNT, and FAIR-performance value compared with the placebo group (each group n = 43, P < 0.05). CONCLUSION: Thus, the consumption of LCF might be beneficial to increase learning and memory through attention and cognitive enhancing effect in normal young people, at an average age of 18 years of age.

Soyo-san reduces depressive-like behavior and proinflammatory cytokines in ovariectomized female rats.

BACKGROUND: Soyo-san is a traditional oriental medicinal formula, a mixture of 9 crude drugs, and it has been clinically used for treating mild depressive disorders. The role of pro- and anti-inflammatory cytokines in psychiatric disorders has been the focus of great research attention in recent years. In the present study, we detected the antidepressant effect of soyo-san in the ovariectomized and repeated stressed female rats. METHODS: This study was designed to evaluate the antidepressant-like effect of soyo-san on the forced swimming test (FST). The rats were randomly divided into the following groups: the nonoperated and nonstressed group (non-op), the nonoperated and stressed group (non-op + ST), the ovariectomized and stress group (OVX) and sham operated and stressed group (sham), the ovariectomized and stressed group (OVX + ST), the ovariectomized, stressed and soyo-san 100 mg/kg treated group (SOY100) and the ovariectomized, stressed and soyo-san 400 mg/kg treated group (SOY400). The rats were exposed to immobilization stress (IMO) for 14 day (2 h/14 day), and soyo-san (100 mg/kg and 400 mg/kg) was administrated during the same time. In the same animals, the levels of corticosterone and interleukin-1-beta (IL-1ß) were examined in the serum. Also, the change of IL-1ß expression in brain regions was examined after behavior test. RESULTS: In the FST, the lower dose (100 mg/kg) of extract was effective in reducing immobility, along with an increase in swimming time. The serum levels of corticosterone and IL-1ß in the SOY groups were significantly lower than those in the control group. In the brain, the expression of IL-1ß positive neurons in the control group were significantly increased in the paraventricular nucleus (PVN) and hippocampus compared to the non-op. However, soyo-san groups significantly reduced the IL-1ß-ir neurons in the PVN and hippocampal regions compared to the control. CONCLUSION: The present results demonstrated that soyo-san effectively reduced behavioral and patho-physiological depression-like responses. TRIAL REGISTRATION: Our results suggest that soyo-san may be useful for immune regulator in repeated stress-induced ovariectomized female rats.

Psychological distress and attentional bias toward acne lesions in patients with acne.

Acne vulgaris is a common inflammatory disease that manifests on the face and affects appearance. In general, facial acne has a wide-ranging negative impact on the psychosocial functioning of acne sufferers and leaves physical and emotional scars. In the present study, we investigated whether patients with acne vulgaris demonstrate enhanced psychological bias when assessing the attractiveness of faces with acne symptoms and whether they devote greater selective attention to acne lesions than to acne-free (control) individuals. Participants viewed images of faces under two different skin (acne vs. acne-free) and emotional facial expression (happy and neutral) conditions. They rated the attractiveness of the faces, and the time spent fixating on the acne lesions was recorded with an eye tracker. We found that the gap in perceived attractiveness between acne and acne-free faces was greater for acne sufferers. Furthermore, patients with acne fixated longer on facial regions exhibiting acne lesions than did control participants irrespective of the facial expression depicted. In summary, patients with acne have a stronger attentional bias for acne lesions and focus more on the skin lesions than do those without acne. Clinicians treating the skin problems of patients with acne should consider these psychological and emotional scars.

Effectiveness of mindfulness and Qigong training for self-healing in patients with Hwabyung and depressive disorder: a protocol for a randomized controlled trial.

Background: Hwabyung is a Korean culture-bound syndrome characterized by anger-related physical and psychological symptoms. Depressive disorder is a common mental illness occurring worldwide, and has been reported to have a high comorbidity rate with Hwabyung. For patients with depressive disorders, differential diagnosis and combined treatment for Hwabyung should be considered. Mindfulness and Qigong may be effective alternatives for regulating emotions such as depression, anxiety, and anger. This study aims to investigate whether Mindfulness and Qigong Training for Self-Healing (MQT-SH) would improve emotional problems in patients with Hwabyung and depressive disorder. Methods: This study will be a two-arm block randomized controlled trial. A total of 64 participants will be recruited and randomly assigned to either experimental or control group. While the experimental group will perform MQT-SH for the first six weeks, the control group will receive no treatment. During the next six weeks, the control group will perform MQT-SH for ethical equity. Assessments will be conducted at baseline, post-intervention (6 weeks) and follow-up (12 weeks). The primary outcomes would be Hwabyung and depression, while the secondary outcomes would include anxiety, anger, and vitality. Discussion: This study will provide a basis for assessing the effectiveness of mindfulness and Qigong training in patients with Hwabyung and depressive disorder. Ethics and dissemination: This study was approved by the Institutional Review Board of Kyung-Hee University Oriental Medicine Hospital in Gangdong (KHNMCOH 2023-09-003). The results will be disseminated through peer-reviewed publications. Trial registration: This trial was registered with the Clinical Research Information Service (CRIS), Republic of Korea, No. KCT0008937 and was registered on November 10, 2023.

Systematic review and meta-analysis of cardiac neurosis for development of clinical practice guidelines of Korean medicine.

Background: The development of clinical practice guidelines in traditional medicine requires evidence that sufficiently reflects the medical field. Cardiac neurosis is a disease that occurs because of problems in the autonomic nervous system and is characterized by symptoms of the circulatory system that are representative of autonomic dysfunction. In traditional medicine, the heart is considered to be involved in mental health problems, and cardiac neurosis is accompanied by a variety of mental symptoms. Furthermore, there is a categorized diagnosis for cardiac neurosis, and active empirical research is being conducted in China. Objective: This study aimed to systematically review and quantitatively synthesize the effects of Korean medicine treatments in patients with cardiac neurosis to develop evidence-based clinical practice guidelines for the treatment of autonomic dysfunction. Methods: Nine databases were searched for articles published before September 13, 2022. The methodological quality of the studies was assessed using the RoB tool. The primary outcomes were somatization, depression, anxiety, and effectiveness rate. The secondary outcome was the rate of adverse effects. Results: Based on a systematic literature review, 151 randomized controlled trials were selected and analyzed. For patients with cardiac neurosis, herbal medicine, combined treatment of herbal medicine and Western medicine, combined treatment of herbal medicine and acupuncture, acupuncture, and combined treatment of acupuncture and Western medicine showed better overall effects than Western medicine alone. Furthermore, the combined treatment of herbal medicine and psychotherapy and that of herbal medicine, psychotherapy, and Western medicine showed an overall better effect than the combined treatment of Western medicine and psychotherapy. Conclusion: A meta-analysis of articles revealed the effectiveness of Korean medicine treatments and verified the effectiveness of a Korean medicine treatment alone, Korean medicine combined treatment, and combined treatment of Korean medicine and Western medicine on cardiac neurosis. Limitations included the inability to verify the cause of high heterogeneity between studies and the poor quality of the included studies. Nevertheless, this systematic review and meta-analysis of cardiac neurosis showed that the disease concept of traditional medicine can also be organized based on the latest research. Future research related to traditional diseases such as these should be conducted.

Effects of a brief Qigong-based stress reduction program (BQSRP) in a distressed Korean population: a randomized trial.

BACKGROUND: Distressed individuals in Korea may benefit from the practice of mind-body exercises such as Qigong. However, the effectiveness of such techniques needs to be investigated. METHODS: Fifty participants who were eligible to this study were randomized into a group receiving a 4-week intervention of a brief Qigong-based stress reduction program (BQSRP) or a wait-list control group. Before and after the intervention period, saliva samples were collected and questionnaires were completed on perceived stress, anxiety, "Hwa-Byung" (anger syndrome), and quality of life. Salivary cortisol has emerged in mind-body therapy research as an easy-to-collect, relatively inexpensive, biologic marker of stress. Salivary corisol were collected to evaluate physiological effect of BQSRP. Between-group comparisons of change from baseline to study completion were analyzed by analysis of covariance for the Perceived Stress Scale and independent two sample t-tests for other measures. RESULTS: Compared with the control group, the BQSRP intervention group displayed significantly larger decreases in Perceived Stress Scale scores (p = 0.0006), State Anxiety scores (p = 0.0028), Trait Anxiety scores (p < 0.0001), personality subscale scores of the Hwa-Byung Scale (p = 0.0321), symptoms scores of the Hwa-Byung Scale (p = 0.0196), and a significantly larger increase in World Health Organization Quality of Life Abbreviated version scores (ps < .05). Salivary cortisol levels were not changed. CONCLUSIONS: The BQSRP appears to be effective in reducing stress perception, anxiety, anger, and improving quality of life (KCT0000056).

Amomum villosum induces longitudinal bone growth in adolescent female rats.

OBJECTIVE: This study was conducted to evaluate the effect of Amomum villosum on longitudinal bone growth. METHODS: Adolescent female Sprague-Dawley rats were divided into 3 groups and treated for 4 days: control (distilled water, p.o.), recombinant human growth hormone (rhGH; 100 microg/kg, s.c.), and A. villosum (500 mg/kg, p.o.) groups. On day 3, tetracycline (20 g/kg, i.p.) was injected for growth plate identification. On days 2, and 4, 5-bromo-2'-deoxyuridine (BrdU) (50 mg/kg, i.p.) was injected to label proliferating cells. On day 5, tibias were dissected and fixed in 4% paraformaldehyde, dehydrated, and sectionedfor immunohistochemistry and histomorphometry. RESULTS: The rate of bone growth in the A. villosum and rhGH groups increased to (410 +/- 44) and (389 +/- 46) microm/day (P<0.01), respectively, as compared with the control (330.7 +/- 34.7) microm/day. The thickness of the growth plates also increased to (591 +/- 37) and (598 +/- 32) microm, respectively, as compared with the control (524 +/- 89) microm (P<0.001). The number of BrdU-positive cells in the chondrocytes of the A. villosum and rhGH groups was also significantly higher (126 +/- 24) and (143 +/- 18) cells/mm2, respectively) than in the control (109 +/- 25) mm2 (P<0.05). Insulin-like growth factor-1 and bone morphogenetic protein-2 in the A. villosum and rhGH groups were highly expressed in the growth plate as compared with the control samples, indicating increased bone formation. CONCLUSIONS: A. villosum could be used to treat growth retardation during adolescence.

Effects of mobile mindfulness training on mental health of employees: A CONSORT-compliant pilot randomized controlled trial.

BACKGROUND: Employee stress and well-being affect organizational efficiency and productivity, as well as physical and psychological health of employees. Mindfulness is believed to reduce stress, prevent diseases, and promote well-being. Mindfulness has been used as the main component of various smartphone-based healthcare applications. Previous studies have suggested that mindfulness applications have a positive effect on employee stress and mental health. However, relatively few randomized controlled trials have examined the effectiveness of mindfulness applications on employees. This study aims to evaluate whether mobile mindfulness training (MMT) as a stress self-management tool improves employees' perceived stress, subjective well-being, and Mibyeong, a condition that is not a disease but shows obvious health abnormalities. METHODS: Participants were recruited through advertisements displayed at 3 workplaces, including a patent attorney's office, a construction company, and a public relations firm. A total of 45 employees were randomly assigned to 1 of 2 groups: the MMT group (Group A) receiving smartphone application-based mindfulness training, and a wait-list control (WLC) group (Group B), who received no intervention. Group A employees conducted MMT following daily and event guidelines for 4 weeks. In contrast, Group B employees did not receive any intervention in that time. The outcome variables were perceived stress, subjective well-being, and Mibyeong. Surveys were conducted at baseline, post-intervention, and follow-up (fourth week post-intervention). RESULTS: Demographic characteristics and baseline assessments were not significantly different between the 2 groups. The results of this study revealed that subjective well-being and Mibyeong were significantly improved in the MMT group compared with the WLC group. Moreover, this improvement was maintained up to at least 4 weeks later. However, perceived stress was not significantly reduced in the MMT group compared to the WLC group. CONCLUSION: Four weeks of MMT improved the subjective well-being and Mibyeong of employees. However, further studies are required to investigate the effect of MMT on other areas of mental health.

Anti-anger Effects of Herbal Medicine: A Mini-Review of Rat Studies.

OBJECTIVE: To analyze the available data on the anti-anger effects of herbal medicines (HMs) as well as their underlying mechanisms in rat models. METHODS: From 6 electronic databases [PubMed, EMBASE, China National Knowledge Infrastructure (CNKI), Wanfang, Oriental Medicine Advanced Searching Integrated System (OASIS), and Research Information Sharing Service (RISS)], relevant animal experiments were searched by using "anger," "rats," and "animal" as search keywords. The last search was conducted on November 22, 2019, and all experiments involving rat models of anger and treatment using HMs published until the date of the search were considered. RESULTS: A total of 24 studies with 16 kinds of HMs were included. Most studies have used the "tail irritating method" and "social isolation and resident intruder" method to establish anger models. According to the included studies, the therapeutic mechanisms of HMs for anger regulation and important herbs by their frequency and/or preclinical evidence mainly incladed regulation of hemorheology (Bupleuri Radix, Paeoniae Radix Alba, and Glycyrrhizae Radix), regulation of sex hormones (Bupleuri Radix, Cyperi Rhizoma, and Paeoniae Radix Alba), regulation of neurotransmitters (Cyperi Rhizoma), regulation of anger-related genes (Bupleuri Radix, Glycyrrhizae Radix, and Paeoniae Radix Alba), and other effects. Overall, Liver (Gan) qi-smoothing herbs including Bupleuri Radix and Cyperi Rhizoma were the most frequently used. CONCLUSIONS: This review found the frequent methods to establish an anger model, and major mechanisms of anti-anger effects of HMs. Interestingly, some Liver qi-smoothing herbs have been frequently used to investigate the anti-anger effects of HM. These findings provide insight into the role and relevance of HMs in the field of anger management.

Meditation-based intervention for obsessive-compulsive disorder: A PRISMA-compliant systematic review and meta-analysis.

BACKGROUND: The purpose of this study was to investigate the effects of the meditation-based intervention on obsessive-compulsive disorder (OCD). METHODS: The following databases were searched up to April 2021: the Cochrane Central Register of Controlled Trials (CENTRAL), EMBASE, Medline (via PubMed), PsycARTICLES, 4 Korean databases (Korean Medical Database [KMbase], Koreanstudies Information Service System [KISS], National Digital Science Library [NDSL], and Oriental Medicine Advanced Searching Integrated System [OASIS]), and China National Knowledge Infrastructure (CNKI). The search terms related to meditation-based intervention and OCD were used. This systematic review was based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses. The selected articles were evaluated using the Cochrane risk of bias tool. The Review Manager (RevMan) 5.4 was used to perform the meta-analysis. RESULTS: In all, 16 randomized controlled trials were selected. The meta-analysis showed that the group receiving the treatment combining medication and meditation-based intervention for OCD showed a more significant post-treatment improvement in Yale-Brown obsessive compulsive scale than the group receiving medication only. Compared with other non-medication interventions that are known to be effective in treating OCD, the Yale-Brown obsessive compulsive scale showed a significant improvement immediately after the meditation-based intervention. However, no significant difference was found in the follow-up monitoring data across all examined cases. CONCLUSION: This study was conducted to verify the effects of meditation-based intervention on OCD. The results suggested that combined treatment with medication and meditation-based intervention was more effective in treating OCD than medication alone; the positive effects of meditation-based intervention may be greater than the effects of other non-medication interventions. However, the lack of significant difference in the follow-up indicates that long-term effect of meditation-based interventions is unclear. TRIAL REGISTRATION NUMBER: PROSPERO CRD42021244408.

How do children with Tourette's syndrome and their caregivers live with the disorder? A systematic review of qualitative evidence.

Background: Tourette's syndrome (TS) is a childhood neurodevelopmental disorder characterized by sudden, repetitive, involuntary, and irregular muscle movement and vocalization. Recently, non-pharmaceutical methods, such as behavioral therapy, psychotherapy, and deep brain stimulation, have been introduced as alternatives to pharmacological treatment for TS. This study aimed to systematically review and synthesize qualitative evidence on the experiences of children with TS and their caregivers. A meta-synthesis of qualitative evidence could help provide a comprehensive understanding of the challenges experienced by children with TS and their caregivers with the aim of providing more effective treatment and services for them. Materials and methods: A systematic search was conducted using MEDLINE/PubMed, EMBASE, Cumulative Index to Nursing and Allied Health Literature, PsycARTICLES, and three Korean databases (Korean Medical Database, Research Information Sharing Service, and ScienceON) in July 2021. Studies were included if they collected and analyzed qualitative data from children with tic disorder or TS, or their caregivers. Qualitative research findings on the experiences and perspectives of children with TS and their caregivers were critically appraised and synthesized using the Joanna Briggs Institute methodology. Results: Eight eligible studies were included. The findings from these studies (i.e., themes or subthemes of qualitative research) were aggregated into categories (a group of similar findings) and synthesized findings (a group of categorized findings). Ultimately, the 60 findings were aggregated into 15 categories. Finally, four synthesized findings were derived from the 15 categories: (i) continuation of challenging daily life, (ii) denying that TS causes emotional distress, (iii) accepting and understanding TS as part of oneself, and (iv) looking to the future. Conclusion: Children with TS and their caregivers experience physical and psychological distress and social deprivation. Avoiding and suppressing TS causes secondary distress such as guilt. However, seeking social support and accepting the disorder reduce the distress caused by symptoms and lays the foundation for later growth. Even in the face of adversity, children with TS and their caregivers find personal value and acquire a more open and optimistic attitude toward life. This review shows that acceptance-based therapy and social support should be provided for the treatment and management of TS.

Efficacy and safety of Gyejibokryeong-hwan (GBH) in major depressive disorder: study protocol for multicentre randomised controlled trial.

BACKGROUND: Gyejibokryeong-hwan (GBH) is an herbal medicine composed of five herbs. It has been widely used to treat gynaecological diseases in traditional East Asian medicine. Recent animal studies suggest antidepressant effects of GBH. In this trial, we explore the efficacy and safety of GBH in patients with major depressive disorder and to identify the optimal dose for the next phase III trial. METHODS: This trial will enrol 126 patients diagnosed with major depressive disorder and not treated with antidepressants. Participants will be randomised to receive a high or a low dose of GBH or placebo granules. The study drugs will be administered three times a day, for 8 weeks. The 17-item Hamilton Depression Rating Scale (HDRS) will be used to measure the severity of depressive symptoms at weeks 2, 4, 6, 8, and 12. The primary efficacy endpoint is the change from baseline in HDRS-17 total score post-treatment at week 8. Analysis of covariance will be based on the baseline HDRS-17 total score and site as the covariates. Safety assessment will be based on the frequency of adverse events. The severity and causality of the study drug will be assessed. DISCUSSION: This study is designed to evaluate the efficacy and safety of GBH granules compared with placebo in patients with major depressive disorder. TRIAL REGISTRATION: Clinical Research Information Service KCT0004417 . Registered on November 1, 2019 (prospective registration).

Electroacupuncture plus moxibustion for major depressive disorder: A randomized, sham-controlled, pilot clinical trial.

BACKGROUND: The first treatment option for major depressive disorder (MDD) is antidepressants, however, there is substantial demand for alternative therapies due to its low compliance and remission rates. This study was aimed to explore the effectiveness, safety, and feasibility of electroacupuncture plus moxibustion therapy for MDD. METHODS: Thirty adults with MDD were randomly assigned to the treatment group (TG) or control group (CG). The TG was treated with electroacupuncture plus moxibustion, and the CG received sham interventions at non-acupoints for 8 weeks. The primary outcome measure was the intergroup difference of the mean change of total score of the Hamilton rating scale for depression (HRSD) between baseline and week 9. Secondary outcome measures were Beck's depression inventory, insomnia severity index, the state-trait anxiety inventory, the EuroQol-5 dimension index, the measure yourself medical outcome profile version 2, and frontal alpha asymmetry measured by electroencephalography. Adverse events (AEs) were monitored for safety assessment. RESULTS: The primary outcome measure was not significantly different between the two groups (p=0.2641), although the scores of HRSD in both groups improved significantly after treatment. No significant difference was identified between groups in secondary outcome measures. The incidence of AE was not significantly different between the two groups (p=0.1067). CONCLUSION: A clinical trial using electroacupuncture plus moxibustion for MDD seems feasible. However, further studies with the larger size, adopting ideal controls are warranted to provide a confirmative conclusion to the efficacy and safety of electroacupuncture plus moxibustion for MDD. TRIAL REGISTRATION: The protocol was registered at Korean Clinical Trial Registry (CRIS-KCT0001810).

Erratum: Withdrawal notice to: Electroacupuncture plus moxibustion for major depressive disorder: A randomized, sham-controlled, pilot clinical trial.

A multicenter registry of neuropsychiatric outpatients in Korean medicine hospitals (KMental): Protocol of a prospective, multicenter, registry study.

INTRODUCTION: Mental health is an important global health concern. In Korea, many people visit Korean medicine clinics due to Stagnation syndrome and Hwabyung (cultural idioms of distress). METHODS AND ANALYSIS: We established a research collaboration comprising of professionals from 8 Korean medicine hospitals and planned a prospective, multicenter registry study. Demographic, socioeconomic, and clinical data will be collected from patients with mental disorders visiting the Korean medicine neuropsychiatric department of Korean medicine hospitals. We will include major psychiatric diagnoses related to neurosis and Korean traditional mental disorders such as Stagnation syndrome and Hwabyung.We expect to identify comprehensive characteristics of participants, measure the severity of their symptoms or distress, and investigate patterns of Korean medicine interventions and treatment responses for both the short-term and long-term (at least 4 years). Additionally, this study will include Health Insurance Review & Assessment Service data to analyze the medical use of registered patients before and after registration, in case the participant submits the consent form for personal information collection and use.To analyze the effectiveness of Korean medicine treatment for the participants, stratified or corrected analyses of age, sex, and diagnosis will be performed. The difference in the change in the psychometric measurements, quality of life measured by short form 36, and quality-adjusted life years will be calculated to evaluate the effectiveness of Korean medicine treatment.

Gami-Chunghyuldan ameliorates memory impairment and neurodegeneration induced by intrahippocampal Aß 1-42 oligomer injection.

Soluble oligomeric forms of amyloid beta (AßO) are regarded as a main cause of synaptic and cognitive dysfunction in Alzheimer's disease (AD) and have been a primary target in the development of drug treatments for AD. The present study utilized a mouse model of AD induced by intrahippocampal injection of AßO (10 µM) to investigate the effects of Gami-Chunghyuldan (GCD), a standardized multi-herbal medicinal formula, on the presentation of memory deficits and neurohistological pathogenesis. GCD (10 and 50mg/kg/day, 5 days, p.o.) improved AßO-induced memory impairment as well as reduced neuronal cell death, astrogliosis, and microgliosis in the hippocampus. In addition, GCD prevented AßO-triggered synaptic disruption and cholinergic fiber loss. These results suggest that GCD may be useful in the prevention and treatment of AD.

Is alpha wave neurofeedback effective with randomized clinical trials in depression? A pilot study.

Frontal asymmetric activation has been proposed to be the underlying mechanism for depression. Some case studies have reported that the enhancement of a relative right frontal alpha activity by an asymmetry neurofeedback training leads to improvement in depressive symptoms. In the present study, we examined whether a neurofeedback training designed to increase the relative activity of the right frontal alpha band would have an impact on symptoms of depressive subjects suffering from emotional, behavioral, and cognitive problems. Our results indicated that the asymmetry neurofeedback training increased the relative right frontal alpha power, and it remained effective even after the end of the total training sessions. In contrast to the training group, the placebo control group did not show a difference. The neurofeedback training had profound effects on emotion and cognition. First, we replicated earlier findings that enhancing the left frontal activity led to alleviation of depressive symptoms. Moreover, cognitive tests revealed that the asymmetry training improved performance of executive function tests, whereas the placebo treatment did not show improvement. We preliminarily concluded that the asymmetry training is important for controlling and regulating emotion, and it may facilitate the left frontal lobe function.

Do Cochrane reviews reflect the latest evidence on meditation and mindfulness-based interventions? A snapshot of the current evidence.

Growing evidence emphasizes the importance of meditation and mindfulness-based interventions (MBIs) in clinical settings. Here, we attempted to determine the clinical issues targeted by Cochrane reviews of meditation and MBIs and whether the judgements about quality/certainty as expressed by the Cochrane authors differed from that of non-Cochrane reviews and guidelines. The search database was the Cochrane Database of Systematic Reviews and the search date was December 31, 2019. Screening and selection of reviews was carried out by two independent authors. Overall, 20 reviews and four protocols were selected for this study. The effects of meditation and/or MBIs on various conditions described in the Cochrane reviews seemed ambiguous, with the exception of mindfulness-based stress reduction in breast cancer patients. However, we found some international clinical practice guidelines and latest non-Cochrane reviews describing meditation and MBIs to be more comprehensive and favorable. This gap is likely due to the priority-setting issues, which resulted in a lack of latest up-to-date evidence, as well as gaps in interventions of interest between Cochrane and non-Cochrane reviews.

One-year visiting care service treatment with Korean medicine for a solitary elderly woman in a public health setting: A case report.

In public health, the plight of the solitary elderly is associated with serious social and medical burden. In this vulnerable population, neuropsychiatric complications such as senile depression and dementia as well as chronic pain conditions often co-occur. In this case report, we present a case of an 81-year-old solitary woman who received one year of visiting care service with Korean medicine treatments in a public health setting. During the one year, her pain severity (measured using numeric rating scale) remained moderate after her initial decline and her depressive symptoms and cognitive function scales (Geriatric Depression Scale-Short Form Korean and the Korean version of the Mini-Mental State Examination for Dementia Screening) remained almost unchanged; however, another cognitive function scale (Korean version of the Montreal Cognitive Assessment) showed noticeable improvements. This case report suggests that providing visiting care services with Korean medicine may be a viable strategy for addressing the issues of the solitary elderly.
