Efficacy of acupuncture on cardiovascular complications in patients with diabetes mellitus in Korea: A nationwide retrospective cohort.

OBJECTIVE: The main aim of this study is to investigate whether acupuncture could be an effective complementary treatment for reducing the risk of macrovascular complications in diabetic patients currently taking antidiabetic medications using a nationwide population-based database. METHODS: We conducted a retrospective cohort study to assess the efficacy of acupuncture on cardiovascular complications in diabetic patients using data from patients between 40 and 79 years of age, newly diagnosed with diabetes between 2003 and 2006, found in the National Health Insurance Service-National Sample Cohort (NHIS-NSC) in Korea. From the data, we identified 21,232 diabetic patients who were taking antidiabetic medication between 2003 and 2006. The selected patients were divided into two groups-those who received acupuncture at least three times and those who received no acupuncture (non-acupuncture) in the year following their diagnosis of diabetes. After 1:1 propensity score matching (PSM), each group had 3350 patients, and the observation ceased at the occurrence of a major adverse cardiovascular event (MACE), which was defined as either myocardial infarction, stroke, or death due to cardiovascular cause. RESULTS: After PSM, the acupuncture group had a lower incidence of MACE (hazard ratio [HR]: 0.87; 95% confidence interval [CI]: 0.81-0.94; P = 0.0003) and all-cause mortality (HR: 0.77; 95% CI: 0.70-0.84; P < 0.0001) than the non-acupuncture group; the HRs for stroke-related mortality (HR: 0.75; 95% CI: 0.56-1.00; P = 0.0485), ischemic heart disease mortality (HR: 0.53; 95% CI: 0.34-0.84; P = 0.006) and circulatory system disease mortality (HR: 0.67; 95% CI: 0.55-0.82; P < 0.0001) were lower in the acupuncture group than in the non-acupuncture group in the secondary analysis. CONCLUSION: Our results indicate that diabetic patients receiving acupuncture treatment might have a lower risk of MACE, all-cause mortality and cardiovascular mortality. This population-based retrospective study suggests beneficial effects of acupuncture in preventing macrovascular complications associated with diabetes. These findings call for further prospective cohort or experimental studies on acupuncture treatment for cardiovascular complications of diabetes.

Acupuncture for cancer patients with nausea and vomiting: A protocol for systematic review and meta-analysis.

BACKGROUND: Nausea and vomiting are among the most common adverse effects experienced by cancer patients undergoing treatment worldwide. Their treatment with pharmacologic therapy can often be complicated by medication interactions and other unwanted side effects. The aim of this systematic review and meta-analysis protocol is to assess the effectiveness and safety of acupuncture therapy for treating nausea and vomiting in patients with cancer. METHODS: Three electronic databases and 2 clinical registry platforms will be searched from inception to May 2022: the MEDLINE via PubMed, Embase via Ovid, the Cochrane Central Register of Controlled Trials via the Cochrane Library, the World Health Organisation International Clinical Trials Registry Platform, and National Institutes of Health Clinical trials.gov. Search terms will include nausea, vomiting, cancer, and acupuncture. Two researchers will independently select studies, extract data and assess the risk of bias. The primary outcome will be the incidence of nausea and/or vomiting or other validated outcome measures. Meta-analysis will be carried out using RevMan V.5.4. The quality of evidence from randomized clinical trials will be evaluated with the Grading of Recommendations Assessment, Development and Evaluation System tool. RESULTS: The results will provide a high-quality synthesis of evidence for clinicians in the field of oncology. CONCLUSION: The conclusion is expected to provide evidence to determine whether acupuncture is an effective and safe treatment for cancer patients with nausea and vomiting.

Association between Decreased ITGA7 Levels and Increased Muscle α-Synuclein in an MPTP-Induced Mouse Model of Parkinson's Disease.

Parkinson's disease (PD) is a neurodegenerative disease characterized by the loss of dopaminergic neurons in the substantia nigra (SN), reducing dopaminergic levels in the striatum and affecting motor control. Herein, we investigated the potential relationship between integrin α7 (ITGA7) and α-synuclein (α-syn) in the muscle of methyl-4-phenyl-1,2,3,6 tetrahydropyridine (MPTP)-induced mice and C2C12 cells. To characterize the pathology of PD, we examined the expression of tyrosine hydroxylase (TH) in the SN of the midbrain. Compared with the control group, MPTP-treated mice showed a significant decrease in TH expression in the SN, accompanied by a significant decrease in muscle ITGA7 expression. Compared with the control group, α-syn expression was increased in the MPTP group. Furthermore, the pattern of α-syn expression in the MPTP group was similar to the ITGA7 expression pattern in the control group (linear forms). To determine the relationship between ITGA7 and PD, we examined the expression of ITGA7 and α-syn after ITGA7 knockdown using siRNA in C2C12 cells. ITGA7 expression significantly decreased while α-syn expression significantly increased in siRNA-treated C2C12 cells. These results suggest that decreased ITGA7 muscle expression could increase α-syn expression. Moreover, α-syn accumulation, induced by decreased muscle ITGA7, might contribute to PD pathology.

Data mining-based clinical profiles of substance use-related emergency department utilizers.

OBJECTIVE: Substance-use is a prevalent presentation to the emergency department (ED); however, the clinical characterization of patients who are treated and discharged without admission for further treatment is under-investigated. The study aims to define and characterize the clinical profiles of this patient population. METHODS: Patients' presentations were examined by clinical data mining (chart review) of ED records of substance use-related events of individuals discharged without admission for further treatment. Records (N = 199) from three major hospitals in New York City from March and June 2017 were randomly sampled with primary diagnosis of alcohol, opioid-related and other psychoactive substance-use presentations. Qualitative thematic coding of clinical presentation with inter-rater reliability was performed. Quantitative distinctive validity tested independence through Pearson's chi-squared and analysis of variance using Fisher's F-test. RESULTS: Six distinct clinical profiles were identified, including, High Utilizers (chronically intoxicated with comorbid health conditions) (36.7%), Single Episode (20.1%), Service Request (14.1%), Altered Mental Status (13.6%), Overdose (9.0%), and Withdrawal (7.5%). The profiles differed (p < 0.05) in age, housing status, payor, mode of arrival, referral source, index visit time, prescribed treatment, triage acuity level, psychiatric history, and medical history. Differences (p < 0.05) between groups across clinical profiles in age and pain level at triage were observed. CONCLUSIONS: The identified clinical profiles represent the broad spectrum and complex nature of substance use-related ED utilization, highlighting critical factors of psychosocial and mental-health comorbidities. These findings provide a preliminary foundation to support person-centered interventions to decrease substance use-related ED utilization and to increase engagement/linkage of patients to addiction treatment.

Anti-rheumatic, and analgesic effects by the parent tuberous roots of Aconitum jaluense in adjuvant induced arthritis rats.

AIM OF THE STUDY: The aim of this study was to test the anti-rheumatic effects of A. jaluense tubers in acute and chronic arthritis rats, and to assign its ingredients through UHPLC-TOF/MS. MATERIALS AND METHODS: Subcutaneous injection of carrageenan for acute arthritis and complete Freund's adjuvant (CFA) for chronic arthritis was carried out in the hind paw of SD rats. The paw volume was measured by a plethysmometer thermal hyperalgesia was tested using a thermal plantar tester, and mechanical hyperalgesia was evaluated by ankle flexion evoked vocalizations. The expression of c-Fos in the brain hippocampus was measured with the avidin-biotin-peroxidase technique. The ingredients were assigned by UHPLC-TOF/MS, chromatography was performed by UHPLC system with DAD detector and BEH C18 column, and spectroscopy was conducted by ESI-MS system. RESULTS AND DISCUSSION: The 80% ethanoic extract of A. jaluense tubers showed an acute anti-inflammatory effect by suppressing the edema volume in the hind paw of carrageenan-stimulated rats. In addition, A. jaluense tubers exerted an anti-rheumatic activity by reducing the secondary swelling volume from an immunological reaction in the left hind paw of CFA-induced chronic arthritis rats. Additionally, oral treatment with the 80% ethanoic extract -showed potent analgesic effects in the arthritis rats by recovering the paw withdrawal latency stimulated by the thermal hyperalgesia and by reducing the vocalization scores evoked by ankle flexion on both hind paws. Moreover, its treatment also indicated an anti-psychiatric effect by controlling the c-Fos protein expression of the brain hippocampus in CFA-stimulated arthritis rats. These results suggested that these therapeutic effects were exhibited by less toxic mono-esterified diterpenoid alkaloids (MDAs), and nontoxic non-esterified diterpenoid alkaloids (NDAs). CONCLUSION: A. jaluense tubers may act as viable therapeutic or preventive candidates for acute and chronic arthritis, particularly, for immune-inflammatory rheumatoid arthritis to suppress the pain and psychiatric condition.

Decrease in ITGA7 Levels Is Associated with an Increase in α-Synuclein Levels in an MPTP-Induced Parkinson's Disease Mouse Model and SH-SY5Y Cells.

We investigated the potential association between integrin α7 (ITGA7) and alpha-synuclein (α-syn) in a methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-induced Parkinson's disease (PD) mouse model. Tyrosine hydroxylase (TH), ITGA7, and α-syn expression in the substantia nigra (SN) of the brain were observed to examine the pathological characteristics of PD. To determine the relationship between ITGA7 and PD, the expression of TH and α-syn was investigated after ITGA7 siRNA knockdown in SH-SY5Y cells. The ITGA7 microarray signal was decreased in the SN of the MPTP group, indicating reduced ITGA7 expression compared to that in the control. The expression patterns of ITGA7 in the control group and those of α-syn in the MPTP group were similar on immunohistochemical staining. Reduction in ITGA7 expression by ITGA7 siRNA administration induced a decrease in TH expression and an increase in α-syn expression in SH-SY5Y cells. The decreased expression of ITGA7 significantly decreased the expression of bcl2 and increased the bax/bcl2 ratio in SH-SY5Y cells. These results suggest that reduced ITGA7 expression may be related to increased α-syn expression and apoptosis of dopaminergic cells in an MPTP-induced PD mouse model. To the best of our knowledge, this is the first study to show an association between ITGA7 and PD.

Developments in the first year of a resilience-focused program for health care workers.

The present article comprises a one-year retrospective review of the efforts of the Mount Sinai Center for Stress, Resilience and Personal Growth, an initiative to support the resilience and well-being of health care workers that was founded amid the first peak of the pandemic in New York in 2020. Specific offerings to date have included evidence-backed resilience workshops, a digital health platform, and a specialty screening and treatment service. All services have been modified or expanded in response to changing needs and are subject to ongoing research. Robust evidence-based programming that addressing health care worker well-being, regardless of role, may prove beneficial to institutions well beyond the pandemic.

Association of decreased triadin expression level with apoptosis of dopaminergic cells in Parkinson's disease mouse model.

BACKGROUND: Parkinson's disease (PD) represent a loss of dopaminergic neurons in the substantia nigra (SN) of the midbrain. However, its cause remains unknown and Triadin (TRDN) function in the brain is also unknown. To examine the relationship between TRDN and PD, the expression levels of protein related to PD in TRDN knockdown status were studied in the SH-SY5Y cells. Cell viability and apoptosis were assessed to examine the apoptosis effect on dopaminergic cells by decreased TRDN, and the levels of the proteins related to apoptosis were also confirmed. RESULTS: This study confirmed decreased TRDN expression level (P < 0.005) at the SN in a 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine-induced PD mouse model and identified the functional features of TRDN. Our results showed a relationship between TRDN expression and PD in that reduced TRDN level induced PD-like characteristics. Interestingly, there was TRDN expression in the regions where dopaminergic cells are in the SN, and the expression patterns of TRDN and tyrosine hydroxylase (TH) were similar. Decreased TRDN level also induced apoptotic characteristics and the Fluorescence-activated cell sorting analysis results showed that apoptosis increased (P < 0.05) as the TRDN small interfering RNA concentration increased. The cytotoxicity assay revealed that cell viability also decreased (P < 0.0005) in the same condition as that in the Fluorescence-activated cell sorting analysis. CONCLUSIONS: Decreased TRDN level could be related with the apoptotic death of dopaminergic cells at the SN in PD, and TRDN administration could give a positive effect on PD by reducing apoptotic cell death.

Efficacy of Acupuncture for Insomnia: A Systematic Review and Meta-Analysis.

Patients with insomnia frequently use acupuncture as an alternative treatment to pharmacotherapy globally. The aim of this paper is to assess the effect of acupuncture on insomnia. Seven medical databases, including MEDLINE, EMBASE, CENTRAL, CNKI, RISS, NDSL, and OASIS, were used to identify studies published through July 09, 2020. Twenty-four randomized controlled trials (RCTs) were included in this qualitative review comparing acupuncture to either pharmacotherapy or sham-acupuncture therapy. Methodological quality was assessed, using the Cochrane risk of bias (ROB). In the subsequent quantitative meta-analysis of studies comparing acupuncture versus pharmacotherapy, fifteen RCTs demonstrated that acupuncture had a significant effect on patients with insomnia as assessed by the Pittsburgh sleep quality index (PSQI) (RR: -0.74; 95% CI: -1.07 to -0.40; [Formula: see text] ¡0.0001; [Formula: see text] = 89%; [Formula: see text] = 1475). A subgroup analysis showed that there was no significant effect after weeks 1 and 2, but six studies found that acupuncture had a significant effect insomnia at week 3 (RR: -0.97; 95% CI: -1.65 to -0.28; [Formula: see text] = 0.006; [Formula: see text] = 91%; [Formula: see text] = 463) and nine studies demonstrated a significant effect at week 4 (RR: -0.70; 95% CI: -1.15 to -0.25; [Formula: see text] = 0.002; [Formula: see text] = 85%; [Formula: see text] = 594). These results suggest that insomnia patients may experience significant improvement in symptoms after more than three weeks of acupuncture treatment compared to pharmacological treatments.

Anti-inflammatory, and anti-arthritic effects by the twigs of Cinnamomum cassia on complete Freund's adjuvant-induced arthritis in rats.

ETHNOPHARMACOLOGICAL RELEVANCE: The young branches of C. cassia Blume (Cinnamomi Ramulus; Guizhi; ; C. cassia twigs) have long been used as an anti-pyretic, anti-rheumatic, anti-spasmodic and stomachic in traditional medicine. AIM OF THE STUDY: The aim of this study was to test the anti-inflammatory, anti-nociceptive, and anti-arthritic effects of Cinnamomum cassia twigs in acute and chronic arthritis rats. MATERIALS AND METHODS: Subcutaneous injection of carrageenan for acute inflammation and complete Freund's adjuvant (CFA) for chronic arthritis was carried out in the hind paw of SD rats. The paw volume was measured by a plethysmometer; thermal hyperalgesia was tested using a thermal plantar tester; hyperalgesia was evaluated by ankle flexion evoked vocalizations. The c-Fos expression in the lumbar spinal cord was measured with the avidin-biotin-peroxidase technique. The nitric oxide (NO) generation in lipopolysaccharide (LPS)-induced RAW 264.7 cells was tested by Griess assay. RESULTS AND DISCUSSION: An 80% ethanoic extract of the C. cassia twigs exhibited chronic anti-inflammatory and anti-arthritic activities by reducing the edema volume in the paws of CFA-induced chronic arthritis in rats. In addition, it showed analgesic effects through the recovery of the paw withdrawal latency stimulated by thermal hyperalgesia, and suppressing the vocalization scores evoked by ankle flexion in the hind paws of the arthritis rats. It also controlled c-Fos expression in the lumbar spinal cord of the arthritis rats. Moreover, the addition its 80%-ethanoic extract, specifically, its ethyl acetate fraction, powerfully suppressed the paw swelling in carrageenan-stimulated arthritis and the NO production in LPS-induced murine immune cells. CONCLUSION: C. cassia twigs may act as a viably sufficient therapeutic or preventive candidate for osteoarthritis and rheumatoid arthritis; additionally, it could prevent gastrointestinal damage with its gastric protection.

A "Mental Health PPE" model of proactive mental health support for frontline health care workers during the COVID-19 pandemic.

We summarize in this article the development, roll out, and preliminary outcomes of a large-scale proactive mental health support model for frontline healthcare workers during the early stages of the COVID-19 pandemic, specifically during New York City's initial case surge in March through June of 2020. This paper summarizes the program design and output for two types of dedicated teams of behavioral health clinicians: 1) Mental Health Liaisons, who provided preventative support to COVID-19 hospital units and Emergency Departments, and 2) Mental Health Crisis Response Teams, who staffed 24/7 crisis response lines to support and mitigate staff crises as needed. In addition to the specifics of this model, we discuss the strategies, rewards, and difficulties of rapidly staging and evaluating such a model in the context of an ongoing disaster situation. We also offer recommendations for how this multi-dimensional model may be replicated in other settings.

Effects of acupuncture on cardiovascular risks in patients with hypertension: a Korean cohort study.

OBJECTIVES: The aim of this study was to investigate the effects of acupuncture on major adverse cardiovascular events (MACE), myocardial infarction, stroke and death in hypertensive patients taking anti-hypertensives. METHODS: Using the Korean National Health Insurance Service-National Sample Cohort (NHIS-NSC) database, this study identified 59,370 patients taking anti-hypertensives who had been diagnosed with hypertension between 2003 and 2006. They were divided into acupuncture and non-acupuncture groups. The follow-up period ended with the diagnosis of myocardial infarction, stroke or death. After propensity score matching (PSM), there were 18,011 patients each in the non-acupuncture and acupuncture groups. We calculated the incidence rate, hazard ratio (HR) and 95% confidence interval (CI) for MACE, myocardial infarction, stroke and death in patients with hypertension using a stratified Cox proportional hazard model. In addition, secondary outcome analyses for stroke and cardiovascular mortality were performed. RESULTS: After PSM, the HRs for MACE (0.83, 95% CI 0.80-0.86), all-cause mortality (0.73, 95% CI 0.70-0.76) and myocardial infarction (0.85, 95% CI 0.79-0.92) were significantly lower in the acupuncture group than in the non-acupuncture group. Moreover, the HRs for stroke-related mortality, hemorrhage stroke-related mortality, ischemic stroke-related mortality, ischemic heart disease-related mortality and circulatory system disease-related mortality were significantly lower in the acupuncture group than in the non-acupuncture group. CONCLUSION: This observational study with long-term follow-up extends the evidence base in support of the effectiveness of acupuncture for the management of hypertension and potentially reduce the burden of cardiovascular disease.

Mount Sinai's Center for Stress, Resilience and Personal Growth as a model for responding to the impact of COVID-19 on health care workers.

The COVID-19 pandemic is anticipated to have a prolonged adverse mental health impact on health care workers (HCWs). The supportive services implemented by the Mount Sinai Hospital System in New York for its workers culminated in the founding of the Mount Sinai Center for Stress, Resilience, and Personal Growth (CSRPG). CSRPG is an innovative mental health and resilience-building service that includes strong community engagement, self- and clinician-administered screening, peer co-led resilience training workshops, and care matching. The long-term sustainability of similar programs across the United States will require federal funding.

Acupuncture Inhibits the Increase in Alpha-Synuclein in Substantia Nigra in an MPTP- Induced Parkinsonism Mouse Model.

Parkinson's disease, a progressive neurodegenerative disease, is caused by the loss of dopaminergic neurons in the substantia nigra (SN). It is characterized by the formation of intracytoplasmic Lewy bodies that are primarily composed of the protein alpha-synuclein (α-syn), along with dystrophic neurites. Acupuncture stimulation results in an enhanced survival of dopaminergic neurons in the SN in Parkinsonism animal models. We investigated the role of acupuncture in inhibiting the increase in α-syn expression that is related to dopaminergic cell loss in the SN in a chronic 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) Parkinsonism mouse model. In this model, acupuncture stimulation at GB34 and LR3 attenuated the decrease in tyrosine hydroxylase in the SN. Moreover, acupuncture stimulation attenuated the increase in α-syn in SN. Acupuncture stimulation also maintained the phosphorylated α-syn on serine 129 at levels similar to the control group. Our findings indicate that the MPTP-mediated increase in α-syn, and the acupuncture-mediated inhibition of the increase in α-syn, may be responsible for the neuroprotective effects of acupuncture in the SN following damage induced by MPTP.

Mechanism of the neuroprotective effect of injecting brain cells on ST36 in an animal model of Parkinson's disease.

In Parkinson's disease, the dopaminergic neurons of the brain are destroyed. Dopamine is an important neurotransmitter that acts on the basal ganglia of the brain, allowing precise body movement. In the early stages of Parkinson's disease, levodopa appears to alleviate clinical symptoms; however, during long-term use, motor complications occur. There is no clear treatment or remedy for Parkinson's disease; therefore, the development of novel therapies is urgently required. In the present study, mouse choroid plexus cells were transplanted into ST36 in a mouse model of Parkinson's disease to determine whether the motor function could be restored. Pole tests showed changes in motor dysfunction in the mice. The athletic ability of the mice was significantly lowered after 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) injection and significantly increased after choroidal neuron cell treatment. Injection of di-alkyl indocarbocyanine (DiI) (as a trace substance) confirmed that the choroid plexus cells injected into acupuncture point ST36 were transferred to the brain. In the Parkinson's disease model, choroid plexus cell injection into ST36 inhibited the decrease in tyrosine hydroxylase (TH) expression and decreased the activation of inflammatory factors mitochondrial cytochrome C oxidase (COX2) and inducible NO synthase (iNOS). Apoptosis factors Cytochrome C and BCL2 associated X, apoptosis regulator (BAX) levels were decreased and B-Cell CLL/Lymphoma 2 (BCL2) levels were increased. Taken together, these results suggest that the injection of choroid plexus cell at ST36 had neuroprotective effects in the Parkinson's disease mouse model. The results suggest new possibilities for the treatment of Parkinson's disease.

The Relationship Between Linguistic Ability, Multilingualism, and Dementia.

In a recent article of the Journal of Alzheimer's Disease, Hack et al. (2019) argue that linguistic ability rather than multilingualism is a significant predictor of dementia. In their longitudinal study, they investigated 325 religious sisters who were older than 75 years of age. Self-reports were used in order to determine multilingualism. They found that speaking two or three languages did not delay the onset of dementia. However, they did find that individuals speaking four or more languages were less likely to suffer from dementia than those speaking only one language and concluded that having linguistic ability was a more significant predictor of dementia than being multilingual. However, more research is needed in order to identify the characteristics of multilingualism most salient for the risk of dementia. In this commentary, we raise several important methodological and statistical issues that are likely to have affected the findings of Hack et al.'s study. As a result, although their study makes an important contribution to the research field, drawing a conclusion at this time that linguistic ability is more a predictor of dementia than multilingualism would be premature; moreover, their preliminary results cannot be generalized to the general population.

A Systematic Review on the Possible Relationship Between Bilingualism, Cognitive Decline, and the Onset of Dementia.

A systematic review was conducted to investigate whether bilingualism has a protective effect against cognitive decline in aging and can protect against dementia. We searched the Medline, ScienceDirect, Scopus, and ERIC databases with a cut-off date of 31 March, 2019, thereby following the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) protocol. Our search resulted in 34 eligible studies. Mixed results were found with respect to the protective effect of bilingualism against cognitive decline. Several studies showed a protective effect whereas other studies failed to find it. Moreover, evidence for a delay of the onset of dementia of between 4 and 5.5 years in bilingual individuals compared to monolinguals was found in several studies, but not in all. Methodological differences in the set-up of the studies seem to explain these mixed results. Lifelong bilingualism is a complex individual process, and many factors seem to influence this and need to be further investigated. This can be best achieved through large longitudinal studies with objective behavioral and neuroimaging measurements. In conclusion, although some evidence was found for a cognitive reserve-enhancing effect of lifelong bilingualism and protection against dementia, to date, no firm conclusions can be drawn.

Acupuncture Inhibits the Increase in Alpha-Synuclein by Modulating SGK1 in an MPTP Induced Parkinsonism Mouse Model.

Parkinson's disease (PD), a progressive neurodegenerative disease, is caused by the loss of dopaminergic neurons in the substantia nigra (SN). It is characterized by the formation of intracytoplasmic Lewy bodies that are primarily composed of the protein alpha-synuclein ( α -syn) along with dystrophic neurites. Acupuncture stimulation results in an enhanced survival of dopaminergic neurons in the SN in parkinsonism animal models. We investigated the role of acupuncture in inhibiting the increase in α -syn expression that is related with dopaminergic cell loss in the SN in a chronic 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) parkinsonism mouse model. In this model, acupuncture stimulation at GB34 and LR3 attenuated the decrease in tyrosine hydroxylase. Moreover, acupuncture stimulation attenuated the increase in α -syn. We identified that serum- and glucocorticoid-dependent kinase 1 (SGK1) is evidently downregulated in chronic MPTP-intoxication and acupuncture stimulation maintained SGK1 expression at levels similar to the control group. For an examination of the expression correlation between SGK1 and α -syn, SH-SY5Y cells were knocked down with SGK1 siRNA then, the downregulation of dopaminergic cells and the increase in the expression of α -syn were observed. Our findings indicate that the acupuncture-mediated inhibition in the α -syn increase induced by MPTP may be responsible for modulating SGK1 expression.

Does the Bilingual Advantage in Cognitive Control Exist and If So, What Are Its Modulating Factors? A Systematic Review.

Recently, doubts were raised about the existence of the bilingual advantage in cognitive control. The aim of the present review was to investigate the bilingual advantage and its modulating factors. We searched the Medline, ScienceDirect, Scopus, and ERIC databases for all original data and reviewed studies on bilingualism and cognitive control, with a cut-off date of 31 October 2018, thereby following the guidelines of the preferred reporting items for systematic reviews and meta-analysis (PRISMA) protocol. The results of the 46 original studies show that indeed, the majority, 54.3%, reported beneficial effects of bilingualism on cognitive control tasks; however, 28.3% found mixed results and 17.4% found evidence against its existence. Methodological differences seem to explain these mixed results: Particularly, the varying selection of the bilingual participants, the use of nonstandardized tests, and the fact that individual differences were often neglected and that longitudinal designs were rare. Therefore, a serious risk for bias exists in both directions (i.e., in favor of and against the bilingual advantage). To conclude, we found some evidence for a bilingual advantage in cognitive control; however, if significant progress is to be made, better study designs, bigger data, and more longitudinal studies are needed.

A study of the effects of 8-week acupuncture treatment on patients with Parkinson's disease.

BACKGROUND: Parkinson's disease (PD) is a degenerative brain disorder, resulting in decreased neural responses in the supplementary motor area, putamen, and thalamus. Previous research showed that acupuncture was able to improve the motor dysfunction. The primary aim of this study is to assess the efficacy of longer acupuncture treatment for preventing brain degeneration in patients with PD. METHODS: Ten outpatients with PD were recruited from Kyung Hee Medical Hospital. Behavioral and neural responses were examined before and after 8 weeks of acupuncture treatment. A semi-individualized treatment approach was used; patients were treated for 15 minutes with 120-Hz electro-acupuncture at the right GB34 and Taechung (LR3), followed by manual acupuncture based on the individual symptoms of the patient. RESULTS: Immediately after 8 weeks of acupuncture treatment, the Unified Parkinson's Disease Rating Scale (UPDRS) sub-scores and the depression scores for the patients had statistically decreased compared to the scores before acupuncture treatment; moreover, 8 weeks later, these scores remained stable. Compared to the neural responses before the acupuncture stimulation, those after the acupuncture treatment were significantly higher in the thalamus, cingulate gyrus, anterior cingulate, lingual gyrus, parahippocampal gyrus, lateral globus pallidus, mammillary body, middle temporal gyrus, cuneus, and fusiform gyrus. Finally, a positive correlation was found between the UPDRS and the mean magnetic resonance signal change for the thalamus. CONCLUSION: This study found beneficial clinical effects of 8-week acupuncture treatment in the brains of patients with PD.
