Mental stress affects the heart by inducing ischaemia and precipitating myocardial infarction (MI) or direct myocardial injury. Mental stress leads to systemic inflammation. Inflammation is known to cause rapid atheromatous plaque progression, instability and thrombosis—the classic type 1 MI. Inflammation can also lead to type 2 MI or myocarditis and injury. The published data linking systemic inflammation, mental stress and cardiovascular disease will be reviewed to establish the linkage between mind and heart, thereby highlighting the importance of holistically managing the patient, not only addressing separate organ systems. Finally, recent trial evidence showing the value of anti-inflammatory drugs in cardiovascular and mental conditions will be briefly considered.","PeriodicalId":12549,"journal":{"name":"General Psychiatry","volume":null,"pages":null},"PeriodicalIF":11.9,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139051361","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite substantial investments from governments and research institutions globally, current addiction medicine research remains centred in Western countries. However, theories, models and results from western-centric research may not be applicable to different cultures. Non-Western countries such as China and Iran, and Western countries are committed to establishing addiction prevention and treatment tailored to their unique histories and cultures. To foster a global addiction science, it is important to increase the diversity of evidence without preconceived biases. Studying addiction problems across different regions and cultural backgrounds and sharing successful prevention and treatment models can provide a more comprehensive perspective for global addiction science, potentially yielding innovative solutions that benefit all countries. China and Iran have their own unique addiction challenges and treatment experiences and have become important representatives of addiction research progress in countries outside the Western axis. Both China and Iran have rich traditional medicine experiences in addiction medicine, which have been developed over thousands of years of trial and error. These offer valuable insights for refining addiction treatment and preventing relapse. Traditional Chinese medicine has a history of over 2000 years in China and has been used to treat addiction, including substance and non-substance addiction, for the past two centuries. Traditional herbal therapy, which targets multiple systems and mechanisms, is considered effective in relieving withdrawal symptoms and preventing addiction relapse with minimal side effects.2 3 It also has a rehabilitative effect on physical issues caused by long-term drug use, including improvements in immune function and working memory and the prevention of neurological diseases.4 The continuous application of traditional medical therapies in China and Iran has preliminarily proven effective in addiction treatment in Western countries, …","PeriodicalId":12549,"journal":{"name":"General Psychiatry","volume":null,"pages":null},"PeriodicalIF":11.9,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139055901","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Aims To investigate the treatment efficacy of PGx for treatment-resistant depression (TRD) compared with treatment as usual. Methods A systematic search was conducted in PubMed, Embase, the Cochrane Library, Web of Science and PsycINFO to identify relevant studies published from inception to 15 April 2023. Two-arm randomised controlled trials (RCTs) exploring the efficacy of PGx-guided versus unguided treatment for TRD were included. The risk of bias in the included studies was evaluated using the Cochrane risk of bias assessment tool. The overall quality of evidence was assessed using the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach. Results Seven RCTs (n=3003) comparing PGx-guided (n=1492) and unguided (n=1511) groups were identified and analysed. PGx-guided treatment was superior to treatment as usual in response (relative risk (RR)=1.31; 95% confidence interval (95% CI): 1.15 to 1.49; p<0.001) and remission (RR=1.40; 95% CI: 1.09 to 1.80; p=0.009) improvements. Effect sizes for acceptability (RR=0.90; 95% CI: 0.80 to 1.02; p=0.100) and side effect burden (RR=0.58; 95% CI: 0.29 to 1.15; p=0.120) between the two groups were not statistically different. The overall quality of evidence was rated from ‘very low’ (25%) to ‘low’ (75%) based on the GRADE criteria. Conclusions PGx-guided treatment has shown a small overall effect in improving the response and remission rates for patients with TRD. However, these results should be interpreted cautiously because of the few included studies and the low quality of evidence.

Issues associated with the pandemic, such as loss of livelihood, limited access to medical services, reduced social interactions, and economic downturn, could potentially have adverse effects on the population’s mental well-being.5 In November 2021, the World Health Organization (WHO) designated the new variant of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), variant B.1.1.529, as a variant of concern and named it Omicron; its rapid mutation and spread raised a new global health concern.6 The first wave of the Omicron outbreak in mainland China started in Shanghai in late February 2022.5 Subsequently, it led to a few small eruptions in several cities in China,7 despite multifaceted public health interventions. After evaluating the pathogenicity, immunity evasion, transmission of the virus, and possible consequences of the Omicron wave, the State Council of China lifted the strict virus control measures on December 7, 2022.8 The official release from attempting to control the epidemic rapidly ushered in the first widespread wave of Omicron, peaking within a month.

Despite evidence of the beneficial effects of music, the acoustic features that make music effective in therapeutic contexts remain elusive. Aims This study aimed to identify and validate distinctive acoustic features of healing music. Methods We constructed a healing music dataset (HMD) based on nominations from related professionals and extracted 370 acoustic features. Healing-distinctive acoustic features were identified as those that were (1) independent from genre within the HMD, (2) significantly different from music pieces in a classical music dataset (CMD) and (3) similar to pieces in a five-element music dataset (FEMD). We validated the identified features by comparing jazz pieces in the HMD with a jazz music dataset (JMD). We also examined the emotional properties of the features in a Chinese affective music system (CAMS). Results The HMD comprised 165 pieces. Among all the acoustic features, 74.59% shared commonalities across genres, and 26.22% significantly differed between the HMD classical pieces and the CMD. The equivalence test showed that the HMD and FEMD did not differ significantly in 9.46% of the features. The potential healing-distinctive acoustic features were identified as the standard deviation of the roughness, mean and period entropy of the third coefficient of the mel-frequency cepstral coefficients. In a three-dimensional space defined by these features, HMD’s jazz pieces could be distinguished from those of the JMD. These three features could significantly predict both subjective valence and arousal ratings in the CAMS. Conclusions The distinctive acoustic features of healing music that have been identified and validated in this study have implications for the development of artificial intelligence models for identifying therapeutic music, particularly in contexts where access to professional expertise may be limited. This study contributes to the growing body of research exploring the potential of digital technologies for healthcare interventions.

However, the clinical benefits of transcranial direct current stimulation (tDCS) in patients still need to be evaluated. Aims This study examined the role of tDCS in improving cognition and whether the improved cognition is related to altered cortical plasticity. Methods 124 patients with AD were randomly assigned to active tDCS (n=63) or sham tDCS (n=61). The tDCS was applied at the dorsolateral prefrontal cortex for 30 treatment sessions across 6 weeks (5 days per week, 2 days off). The Mini-Mental State Examination and the Alzheimer’s Disease Assessment Scale-Cognitive (ADAS-Cog) were used for cognition evaluation at baseline, week 2 and week 6. The cortical plasticity was represented by motor-evoked potential (MEP) measured with an electromyogram. Results The results showed that multiple courses of active tDCS can improve the cognitive functions of patients with AD, especially in the memory domain (word recall, recall of test instructions and word recognition). In addition, the damaged MEP level was enhanced following active treatment. In the active tDCS group, the improvements in ADAS-Cog total and subitem (word recall and word recognition) scores were negatively correlated with the enhancement of MEP. Conclusions Our research indicates for the first time that twice-a-day tDCS may improve the cognitive function of patients with AD. This study also suggests that cognitive dysfunction may be related to impaired cortical plasticity, which warrants mechanistic investigations of the relationship between cognition and plasticity in the future.
