Real-world efficacy and safety of naltrexone-bupropion therapy in Chinese patients with obesity: A single-centre experience.

PURPOSE: Naltrexone-bupropion (Contrave®) has shown efficacy and safety in large randomised controlled trials, predominantly comprising Caucasians. Data are limited in Asian populations. We carried out a retrospective matched cohort study of Chinese patients with obesity to evaluate the efficacy and safety of naltrexone-bupropion in real-world clinical practice. METHODS: We performed a retrospective matched cohort study of Chinese patients with obesity managed in the Obesity Clinic of Queen Mary Hospital in Hong Kong between 1 January 2016 and 31 December 2020. Electronic health records of patients treated with naltrexone-bupropion were retrieved for body weight and height, obesity-related metabolic parameters, and adverse events over a 12-month period. Age- and sex-matched controls from the Obesity Clinic who were only on self-directed lifestyle management were identified for comparison of weight changes. General linear models were used to analyse the change in body weight over 12 months. RESULTS: Thirty-seven patients treated with naltrexone-bupropion were included (mean age 42.2 ± 8.4 years, 54.1% men, baseline body mass index 37.3 ± 4.6 kg/m2), and 37 age- and sex-matched controls were included. Among the 37 naltrexone-bupropion-treated patients, the mean weight loss was 9.2 ± 5.2% at 6 months and 9.7 ± 8.1% at 12 months, which were significantly more than in controls (p < 0.001). Improvements in the obesity-related parameters were observed in association with weight loss over 12 months. Ten patients (27.0%) discontinued naltrexone-bupropion due to side effects, mainly neurological and gastrointestinal manifestations, within the first 12 months. CONCLUSION: We demonstrated real-world efficacy and safety of naltrexone-bupropion among Chinese patients with obesity.

Nation-wide surveillance of ticks (Acari: Ixodidae) on birds in Singapore.

Surveillance programs focused on bird ticks are often challenging owing to the difficulty in capturing and screening birds as well as the fact that ticks on avian hosts frequently occur at a low prevalence. Nonetheless, elucidating the diversity and host preferences of avian ticks is critical for understanding public health risks posed by both migratory and resident birds. The first nation-wide surveillance program of avian ticks was initiated to examine bird-tick interactions in Singapore, a key juncture along the East Asian-Australasian flyway. Two tick species were detected, namely Haemaphysalis wellingtoni and Rhipicephalus linnaei, while five bird species were found to host ticks in Singapore, namely Columba livia, Gallus gallus, Ixobrychus flavicollis, Lanius cristatus, and Pitta moluccensis. The threats posed to public health by the human-biting tick H. wellingtoni are discussed along with the potential for migratory birds and ticks to transport tick-borne pathogens into, and through, Singapore.

Effectiveness and safety of Liriope Tuber (Liriopis seu Ophiopogonis Tuber, Maidong) included traditional herbal medicine for patients with paroxysmal atrial fibrillation: A systematic review, meta-analysis, and network analysis.

Background: Conventional medicine (CM) for paroxysmal atrial fibrillation (PAF) have limitations and side effects. Integrative approaches, including traditional herbal medicines like Liriope Tuber, are being explored for potential benefits, although evidence remains limited. Methods: In April 2023, a literature search was conducted across nine databases, focusing on randomized controlled trials assessing the effects of Liriope Tuber in traditional herbal medicine (LTHM) on PAF. The risk of bias was evaluated using Version 2 of the Cochrane risk-of-bias tool for randomized trials. A random-effects model was employed for the meta-analysis. Results: A total of 43 studies with 3,743 participants were included. The meta-analysis indicated that adding LTHM to CM reduced PAF frequency (SMD = -0.99, 95 % CI = -1.40 to -0.57, I² = 88 %, N = 16, n = 1266), left atrium diameter (LAD) (MD = -2.39 mm, 95 % CI = -3.09 to -1.68), P-wave dispersion (Pd) (MD = -6.41 ms, 95 % CI = -8.44 to -4.37), high sensitive C-Reactive Protein (hs-CRP) (MD = -1.10 mg/l, 95 % CI = -1.73 to -0.47), and improved left ventricular ejection fraction (LVEF) (MD = 4.71 %, 95 % CI = 3.17 to 6.25). Thirty-four studies raised concerns about bias, with eight showing high risk. Certainty of evidence was rated as "low" for PAF frequency, LAD, Pd, hs-CRP, and LVEF. Conclusion: LTHM combined with CM may reduce PAF frequency. However, due to the complexity of interventions, with Liriope Tuber being only one component of the regimen, high risk of bias, substantial heterogeneity, and indirectness, interpretations should be cautious.

Whole exome sequencing identifies genetic markers of enterovirus susceptibility in East Asians.

Introduction: Following acute enterovirus (EV) infection, outcomes vary based on factors like the immune response, viral cell entry receptor expression levels, tissue tropism, and genetic factors of both the host and virus. While most individuals exhibit mild, self-limited symptoms, others may suffer severe complications or prolonged infections that can lead to autoimmune disorders. Methods: To elucidate host responses to EV infection, we performed whole exome sequencing on blood samples from both infected and uninfected individuals. Our initial focus was on genes encoding EV entry receptors-PSGL-1, SCARB2, and ANAXA2 for EV-A71, and CD155 for poliovirus-and on host genes ACBD3 and PI4KΒ, crucial for EV replication. Results: Although no specific genetic variants directly associated with EV infection were identified, we discovered 118 variants across 116 genes enriched in East Asian populations through multi-layered variant filtering. These variants were further analyzed for their potential impacts on organs, biological processes, and molecular pathways. Phenome-wide association studies were conducted to refine our understanding of their contributions to EV infection susceptibility. Discussion: Our findings aim to develop a predictive panel based on these 118 variants, which could help susceptible individuals during EV outbreaks, guiding targeted clinical interventions and preventative strategies.

Genome-wide association study and polygenic risk score analysis for schizophrenia in a Korean population.

Although large-scale genome-wide association studies (GWASs) have revealed the genetic architecture of schizophrenia, these studies have mainly focused on populations of European ancestry. This study aimed to identify common genetic variants associated with schizophrenia in the Korean population and evaluate the performance of polygenic risk scores (PRSs) derived from large-scale GWASs across ancestries. In the Korean psychiatric GWAS project (KPGP), seven academic institutes and their affiliated hospitals across South Korea recruited a cohort of 1670 patients with DSM-IV-defined schizophrenia and 2271 healthy controls. A total of 6690,822 SNPs were tested for association with schizophrenia. We identified one previously unreported genome-wide significant locus rs2423464 (P = 2.83 × 10-11; odds ratio = 1.65; 95 % confidence interval = 1.43-1.91, minor allele frequency = 0.126). This variant was also associated with increased lysosomal-associated membrane protein family member 5 (LAMP5) gene expression. The PRS derived from the meta-analysis results of East Asian and European GWASs explained a larger proportion of the phenotypic variance in the Korean schizophrenia sample than the PRS of an East Asian or European GWAS. (R2 = 0.073 for meta-analysis; 0.028 for East Asian GWAS; 0.037 for European GWAS). GWASs involving diverse ethnic groups will expand our understanding of the genetic architecture of schizophrenia.

Genotype Analysis of the JR Blood Group in an East Asian Population Using Tetra-Primer ARMS-PCR.

OBJECTIVE: The JR blood group system, officially designated ISBT JR 032, consists of a single antigen called Jra. This is a high frequency antigen in most populations. The Jr(a-) phenotype is more prevalent in Japanese and Asian populations. Individuals with the Jr(a-) blood type can be recognized incidentally by the production of anti-Jr(a) antibodies and verified by the existence of two null ABCG2 alleles. METHODS: We used direct sequencing to analyze the genotype frequency of the ABCG2 null allele (c.376C>T, rs72552713) and compared it with East Asian genomic databases. We developed tetra-primer amplification refractory mutation system-polymerase chain reaction (ARMS-PCR), which is a simple, precise method for determining an individual's genotype and suitable for clinical use, and analyzed a cohort of 300 healthy Koreans. RESULTS: Using direct sequencing, we found that 14 individuals in the cohort carried a heterozygous ABCG2 null allele. We optimized the ARMS-PCR technique to detect and identify this null allele precisely. We identified the presence of this null allele in a heterozygous state using ARMS-PCR. CONCLUSION: The minor allele frequency of the ABCG2 null allele in the Korean cohort was 2.3%. The estimated genotype frequencies of homozygotes and heterozygotes for this null allele are 0.05% and 4.56%, respectively. The newly developed ARMS-PCR assay would be useful for determining the Jr(a-) antigen status in patients who produce anti-Jr(a) antibodies as well as for selecting Jr(a-) blood donors.

Generation of a medicine food homology formula and its likely mechanism in treatment of microvascular angina.

Microvascular angina (MVA) is the most common cause of cardiac ischemic chest pain in patients without obstructive coronary artery disease (CAD) and lacks of effective treatment means. Medicine food homology (MFH) involves substances with both nutritional and medicinal qualities that have the potential to improve MVA symptoms as medicines, dietary supplements. However, research on MFH formula (MFHF) for MVA is not available. The study aims to generate a core MFHF for MVA through data mining and offer scientific backing for the utilization of edible medications in the prevention and alleviation of MVA. 11 databases were utilized to construct a database of MFH drugs, and the MFHF was generated through frequency analysis, association rule analysis, and clustering analysis. The composition of the formula is Codonopsis Radix, Astragali Radix, Platycodonis Radix, Persicae Semen, Glycyrrhizae Radix Et Rhizoma, Angelicae Sinensis Radix, and Allii Macrostemonis Bulbus. Through network pharmacology and molecular docking, we identified five major active components of MFHF: Adenosine, Nonanoic Acid, Lauric Acid, Caprylic Acid, and Enanthic Acid, along with nine core targets (NFKB1, ALB, AKT1, ACTB, TNF, IL6, ESR1, CASP3, and PTGS) for the improvement of MVA. These 5 active components have various biological activities, such as reducing oxidative stress, anti-inflammation, analgesia effect, inhibiting platelet aggregation, vasodilatation, vascular endothelial protection, and cardio-protection. GO and KEGG enrichment analyses revealed that MFHF mainly acted on the response to xenobiotic stimulus, integrative component of the plasma membrane, RNA polymerase II transcription factor activity, ligand-activated sequence-specific DNA binding, pathways in cancer, lipid and atherosclerosis, human cytomegalovirus infection, and the PI3K-Akt signaling pathway, which are the main pathogenesis of MVA.

A practical guide to implementing artificial intelligence in traditional East Asian medicine research.

In this paper, we present a comprehensive guide for implementing artificial intelligence (AI) techniques in traditional East Asian medicine (TEAM) research. We cover essential aspects of the AI model development pipeline, including research objective establishment, data collection and preprocessing, model selection, evaluation, and interpretation. The unique considerations in applying AI to TEAM datasets, such as data scarcity, imbalance, and model interpretability, are discussed. We provide practical tips and recommendations based on best practices and our own experience. The potential of large language models in TEAM research is also highlighted. Finally, we discuss the challenges and future directions of AI application in TEAM, emphasizing the need for standardized data collection and sharing platforms.

Mendelian randomization study of childhood asthma and chronic obstructive pulmonary disease in European and East Asian population.

Objective: The present study aimed to explore the potential causal relationship between childhood asthma and chronic obstructive pulmonary disease (COPD) in European and East Asian populations with Mendelian randomization (MR) analysis. Methods: Based on summary data from genome-wide association studies, single nucleotide polymorphisms (SNPs) associated with childhood asthma were used as instrumental variables. The MR analysis employed the inverse variance weighting, MR-Egger regression and weighted median method to estimate the causal effect between childhood asthma and COPD in European and East Asian populations. Cochran's Q test, MR-PRESSO method and MR-Egger intercept were used to detect heterogeneity, outliers and horizontal pleiotropy, respectively. Leave-one-out analysis applied to assess the effect of removing individual SNP on the estimate of causal association. Results: The MR analysis showed no genetic causal relationship between childhood asthma and COPD. The results of Cochran's Q test, MR-PRESSO and MR-Egger regression indicated the absence of heterogeneity, outliers and horizontal pleiotropy, respectively. Leave-one-out analysis showed no significant difference in the statistical results after exclusion of single SNPs. Conclusions: The MR analysis revealed that there is no causal relationship between childhood asthma and COPD at the genetic level in both European and East Asian populations. Additionally, due to the presence of shared confounding factors and pathogenic genes, further research is needed to comprehensively assess the relationship between childhood asthma and COPD.

A causal relationship between bone mineral density and breast cancer risk: a mendelian randomization study based on east Asian population.

BACKGROUND: Breast cancer (BC) poses significant burdens on women globally. While past research suggests a potential link between bone mineral density (BMD) and BC risk, findings remain inconsistent. Our study aims to elucidate the causal relationship between BMD and BC in East Asians using bidirectional Mendelian randomization (MR). METHODS: Genetic association data for bone mineral density T-scores (BMD-T) and Z-scores (BMD-Z) (Sample size = 92,615) and BC from two different sources (Sample size1 = 98,283; Sample size2 = 79,550) were collected from publicly available genome-wide association studies (GWAS). Single-nucleotide polymorphisms (SNPs) associated with BMD-T and BMD-Z as phenotype-related instrumental variables (IVs) were used, with BC as the outcome. As the primary means of causal inference, the inverse variance weighted (IVW) approach was employed. Heterogeneity analysis was conducted using Cochran's Q test, while MR-Egger regression analysis was implemented to assess the pleiotropic effects of the IVs. Sensitivity analyses were performed using methods such as MR-Egger, weighted median, and weighted mode to analyze the robustness and reliability of the results. The MR-PRESSO method and the RadialMR were used to detect and remove outliers. The PhenoScanner V2 website was utilized to exclude confounding factors shared between BMD and BC. Besides, the Bonferroni correction was also used to adjust the significance threshold. Then, the meta-analysis method was applied to combine the MR analysis results from the two BC sources. Finally, a reverse MR analysis was conducted. RESULTS: The results of the IVW method were consolidated through meta-analysis, revealing a positive correlation between genetically predicted BMD-T ([Formula: see text], [Formula: see text], [Formula: see text]) and BMD-Z ([Formula: see text],[Formula: see text], [Formula: see text]) with increased BC risk. The Cochran's [Formula: see text] test and MR-Egger regression suggested that neither of these causal relationships was affected by heterogeneity or horizontal pleiotropy. The sensitivity analyses supported the IVW results, indicating the robustness of the findings. Reverse MR analysis showed no causal relationship between BC and BMD. CONCLUSION: Our MR study results provide evidence for the causal relationship between BMD and BC risk in East Asian populations, suggesting that BMD screening is of great significance in detecting and preventing BC.

Evolution and legacy of East Asian aurochs.

Aurochs (Bos primigenius), once widely distributed in Afro-Eurasia, became extinct in the early 1600 s. However, their phylogeography and relative contributions to domestic cattle remain unknown. In this study, we analyzed 16 genomes of ancient aurochs and three mitogenomes of ancient bison (Bison priscus) excavated in East Asia, dating from 43,000 to 3,590 years ago. These newly generated data with previously published genomic information on aurochs as well as ancient/extant domestic cattle worldwide through genome analysis. Our findings revealed significant genetic divergence between East Asian aurochs and their European, Near Eastern, and African counterparts on the basis of both mitochondrial and nuclear genomic data. Furthermore, we identified evidence of gene flow from East Asian aurochs into ancient and present-day taurine cattle, suggesting their potential role in facilitating the environmental adaptation of domestic cattle.

The effect of benzylpenicillin prohylaxis after birth on length and weight of syphilis-exposed infants in eastern China.

BACKGROUND: We conducted this study to assess the impact of an intervention to interrupt mother-to-child transmission on the height and weight of syphilis-exposed infants after receiving penicillin prophylaxis after birth and to provide a scientific basis for further elimination of mother-to-child transmission. METHODS: We recruited 419 infants born to syphilis-infected mothers from 2015 to 2020 in Changzhou, and performed 1:1 matching to infants born to syphilis-free mothers during the same period. All infants were followed up to 18 months of age. We collected height and weight data and compared them. RESULTS: At 18 months of age, the height and weight of the syphilis-exposed infants were almost greater than the WHO reference standards. However, when compared with local unexposed infants, there were almost no differences. The boys born to mothers who received two courses of treatment had longer body lengths at 18 months of age than did those born to mothers who did not receive two courses of treatment, and the girls born to mothers who did not receive treatment had lower body weights at 3 months of age than did both treated groups. CONCLUSION: The growth trajectory of infants without congenital syphilis born to syphilis-infected mothers is virtually indistinguishable from that of the general local population. Syphilis-exposed newborns can receive preventive treatment as a public health intervention.

Pain Relief, Functional Recovery, and Chondroprotective Effects of Angelica gigas Nakai in Osteoarthritis Due to Its Anti-Inflammatory Property: An In Vitro and In Vivo Study.

Osteoarthritis (OA), characterized by chronic pain and joint degradation, is a progressive joint disease primarily induced by age-related systemic inflammation. Angelica gigas Nakai (AG), a medicinal plant widely used in East Asia, exhibits promising results for such conditions. This study aimed to evaluate the potential of AG as a drug candidate for modulating the multifaceted pathology of OA based on its anti-inflammatory properties. We evaluated the efficacy of AG in pain relief, functional improvement, and cartilage erosion delay using monosodium iodoacetate-induced OA rats and acetic acid-induced writhing mice, along with its anti-inflammatory effects on multiple targets in the serum and cartilage of in vivo models and lipopolysaccharide-stimulated RAW 264.7 cells. In vivo experiments demonstrated significant analgesic and chondroprotective effects of AG, along with functional recovery, in model animals compared with the active controls. AG dose-dependently modulated inflammatory OA pathology-related targets, including interleukin-1ß, tumor necrosis factor-α, matrix metalloproteinase-13, and cyclooxygenase-2, both in vitro and in vivo. In conclusion, AG could be a potential drug candidate for modulating the multifaceted pathology of OA. Nevertheless, further comprehensive investigations, involving a broader range of compounds, pathologies, and mechanisms, are warranted to validate these findings.

Effectiveness and safety of East Asian herbal medicine for menopausal insomnia: a systematic review and meta-analysis.

Background: Menopausal insomnia significantly impacts the quality of life in women. East Asian herbal medicines (EAHMs) have been traditionally used in Asian countries, but their efficacy and safety require systematic evaluation. This systematic review and meta-analysis aimed to evaluate the effectiveness and safety of EAHM for treating menopausal insomnia. Methods: A comprehensive literature search was conducted across 10 electronic databases from inception until 19 July 2023. Randomized controlled trials (RCTs) investigating EAHM for menopausal insomnia were included. Two reviewers independently screened studies, extracted data, and assessed the risk of bias using the Cochrane risk of bias tool. The primary outcome was sleep quality, insomnia severity, and sleep architecture. Secondary outcomes included total effective rate (TER), menopausal symptoms, and adverse effects. Meta-analysis was conducted using a random-effects model, and the results were calculated as mean differences (MDs) or risk ratios (RRs) and their 95% confidence intervals (CIs). Also, the certainty of evidence was assessed using the GRADE approach. Results: A total of 70 RCTs involving 6,035 participants met the inclusion criteria. The most frequently used EAHMs were modified Suan Zao Ren Tang, and the most frequently used herbal component was Zizyphus jujuba Miller var. spinosa Hu ex H. F. Chou [Rhamnaceae; Zizyphi Semen]. Compared with sedative-hypnotics, EAHM significantly improved sleep quality, as measured by the Pittsburgh Sleep Quality Index (PSQI) (MD -2.18, 95% CI -2.56 to -1.80), and reduced menopausal symptoms, as assessed by the Kupperman Index (MD -4.92, 95% CI -6.03 to -3.80). Similar results were seen when EAHM was added to sedative-hypnotics. When EAHM was additionally used in sedative-hypnotics, similar benefits were shown for PSQI (MD -2.46, 95% CI -3.09 to -1.82) and the Kupperman Index (MD -4.64, 95% CI -5.07 to -4.21). EAHM was generally safer than sedative-hypnotics, with significantly fewer adverse reactions (RR 0.15, 95% CI 0.07-0.34). However, the certainty of evidence was moderate to low. Conclusion: EAHMs, alone or with sedative-hypnotics, may be effective and safe for improving sleep quality and managing menopausal symptoms. Future studies should include diverse populations, rigorous methodologies, and explore mechanisms of action to confirm these findings.

Multitrait Genetic Analysis Identifies Novel Pleiotropic Loci for Depression and Schizophrenia in East Asians.

BACKGROUND AND HYPOTHESIS: While genetic correlations, pleiotropic loci, and shared genetic mechanisms of psychiatric disorders have been extensively studied in European populations, the investigation of these factors in East Asian populations has been relatively limited. STUDY DESIGN: To identify novel pleiotropic risk loci for depression and schizophrenia (SCZ) in East Asians. We utilized the most comprehensive dataset available for East Asians and quantified the genetic overlap between depression, SCZ, and their related traits via a multitrait genome-wide association study. Global and local genetic correlations were estimated by LDSC and ρ-HESS. Pleiotropic loci were identified by the multitrait analysis of GWAS (MTAG). STUDY RESULTS: Besides the significant correlation between depression and SCZ, our analysis revealed genetic correlations between depression and obesity-related traits, such as weight, BMI, T2D, and HDL. In SCZ, significant correlations were detected with HDL, heart diseases and use of various medications. Conventional meta-analysis of depression and SCZ identified a novel locus at 1q25.2 in East Asians. Further multitrait analysis of depression, SCZ and related traits identified ten novel pleiotropic loci for depression, and four for SCZ. CONCLUSIONS: Our findings demonstrate shared genetic underpinnings between depression and SCZ in East Asians, as well as their associated traits, providing novel candidate genes for the identification and prioritization of therapeutic targets specific to this population.

Height and cancer risk in East Asians: Evidence from a prospective cohort study and Mendelian randomization analyses.

BACKGROUND: Height is associated with increased cancer risk, but most studies focus on Western populations. We aimed to evaluate this relationship in East Asians. METHOD: Observational analyses were performed utilizing data from China Kadoorie Biobank (CKB) prospective cohort. Adjusted hazard ratios (HRs) and corresponding 95 % confidence intervals (CIs) were estimated using Cox proportional hazards models. Two-sample Mendelian randomization (MR) analyses explored causal effects between height and cancer using data from Korean Genome and Epidemiology Study (KoGES), Biobank Japan (BBJ), and CKB. RESULTS: Over a median 10.1-years follow-up, 22,731 incident cancers occurred. In observational analyses, after Bonferroni correction, each 10 cm increase in height was significantly associated with higher risk of overall cancer (HR 1.16, 95 % CI 1.14-1.19, P < 0.001), lung cancer (1.18, 95 % CI 1.12-1.24, P < 0.001), esophageal cancer (1.21, 95 % CI 1.12-1.30, P < 0.001), breast cancer (1.41, 95 % CI 1.31-1.53, P < 0.001), and cervix uteri cancer (1.29, 95 % CI 1.15-1.45, P < 0.001). Each 10 cm increase in height was suggestively associated with increased risk for lymphoma (1.18, 95 % CI 1.04-1.34, P = 0.010), colorectal cancer (1.09, 95 % CI 1.02-1.16, P = 0.010), and stomach cancer (1.07, 95 % CI 1.00-1.14, P = 0.044). In MR analyses, genetically predicted height (per 1 standard deviation increase, 8.07 cm) was suggestively associated with higher risk of lung cancer (odds ratio [OR] 1.17, 95 % confidence interval [CI] 1.02-1.35, P = 0.0244) and gastric cancer (OR 1.14, 95 % CI 1.02-1.29, P = 0.0233). CONCLUSIONS: Taller height was significantly related to a higher risk for overall cancer, lung cancer, esophageal cancer, breast cancer, and cervix uteri cancer. Our findings suggest that height may be a potential causal risk factor for lung and gastric cancers among East Asians.

Efficacy and Safety of Orally Administered East Asian Herbal Medicine Combined with Narrowband Ultraviolet B against Psoriasis: A Bayesian Network Meta-Analysis and Network Analysis.

Psoriasis is a chronic, immune-mediated inflammatory skin disease with many complications and a poor prognosis that imposes a significant burden on individuals and society. Narrowband ultraviolet B (NB-UVB) represents a cost-effective non-drug therapeutic intervention for psoriasis. East Asian herbal medicine (EAHM) is currently being investigated for its potential as a safe and effective psoriasis treatment. Consequently, it has the potential to be employed as a combination therapy with NB-UVB. The objective was to ascertain the efficacy and safety of the EAHM with NB-UVB combination therapy and to identify important drugs for further research. In this study, randomized controlled trials (RCTs) were retrieved from ten databases in Korea, China, and Japan. All statistical analyses were conducted using R software version 4.3.0. The primary outcomes were the Psoriasis Area and Severity Index (PASI) and the incidence rate of adverse events (AEs), while the secondary outcomes were hematologic markers and the Dermatology Life Quality Index (DLQI), which reflect the immune-mediated inflammatory pathology of psoriasis. The analysis of 40 RCTs, including 3521 participants, demonstrated that EAHM with NB-UVB combination therapy exhibited a statistically significant superiority over NB-UVB monotherapy with respect to primary and secondary outcomes. The Bayesian network meta-analysis revealed that Investigator Presciption 3 and Ziyin Liangxue Decoction exhibited a consistent relative advantage with respect to each PASI-based efficacy metric. The network analysis estimated the potential influence ranking for all individual herbs according to PageRank centrality. The findings of this study suggest that EAHMs co-administered with NB-UVB may provide additional efficacy and safety-related benefits for patients with psoriasis. However, the quality of evidence is still low, and further high-quality trials are needed to reach more definitive conclusions.

The Generation of Attenuated Mutants of East Asian Passiflora Virus via Deletion and Mutation in the N-Terminal Region of the HC-Pro Gene for Control through Cross-Protection.

East Asian Passiflora virus (EAPV) causes passionfruit woodiness disease, a major threat limiting passionfruit production in eastern Asia, including Taiwan and Vietnam. In this study, an infectious cDNA clone of a Taiwanese severe isolate EAPV-TW was tagged with a green fluorescent protein (GFP) reporter to monitor the virus in plants. Nicotiana benthamiana and yellow passionfruit plants inoculated with the construct showed typical symptoms of EAPV-TW. Based on our previous studies on pathogenicity determinants of potyviral HC-Pros, a deletion of six amino acids (d6) alone and its association with a point mutation (F8I, simplified as I8) were conducted in the N-terminal region of the HC-Pro gene of EAPV-TW to generate mutants of EAPV-d6 and EAPV-d6I8, respectively. The mutant EAPV-d6I8 caused infection without conspicuous symptoms in N. benthamiana and yellow passionfruit plants, while EAPV-d6 still induced slight leaf mottling. EAPV-d6I8 was stable after six passages under greenhouse conditions and displayed a zigzag pattern of virus accumulation, typical of a beneficial protective virus. The cross-protection effectiveness of EAPV-d6I8 was evaluated in both N. benthamiana and yellow passionfruit plants under greenhouse conditions. EAPV-d6I8 conferred complete cross-protection (100%) against the wild-type EAPV-TW-GFP in both N. benthamiana and yellow passionfruit plants, as verified by no severe symptoms, no fluorescent signals, and PCR-negative status for GFP. Furthermore, EAPV-d6I8 also provided complete protection against Vietnam's severe strain EAPV-GL1 in yellow passionfruit plants. Our results indicate that the attenuated mutant EAPV-d6I8 has great potential to control EAPV in Taiwan and Vietnam via cross-protection.

Rosacea in East Asian populations: Clinical manifestations and pathophysiological perspectives for accurate diagnosis.

Rosacea is a chronic inflammatory disorder primarily affecting the facial skin, prominently involving the cheeks, nose, chin, forehead, and periorbital area. Cutaneous manifestations encompass persistent facial erythema, phymas, papules, pustules, telangiectasia, and flushing. The pathogenesis of rosacea is associated with various exacerbating or triggering factors, including microbial infestation, temperature fluctuations, sunlight exposure, physical exertion, emotional stress, consumption of hot beverages and spicy foods, and exposure to airborne pollen. These environmental factors interact with genetic predispositions in the development of rosacea. The roles of the lipophilic microbiome, ultraviolet radiation, nociceptive responses, and vascular alterations have been proposed as significant factors in the pathogenesis. These insights contribute to understanding the anatomical specificity of facial involvement and the progressive nature of rosacea. East Asian skin, predominantly classified as Fitzpatrick skin phototypes III to IV, is characterized by relatively diminished skin barrier function and increased sensitivity to irritants. Airborne pollen exposure may particularly act as a trigger in East Asian individuals, possibly mediated through toll-like receptors. The lack of specificity in objective clinical and histopathological findings leads to diagnostic challenges for individuals with colored skin, including East Asians, particularly when erythema is the sole objective manifestation. An alternative diagnostic scheme may thus be necessary. A diagnostic approach emphasizing vascular manifestations and nociceptive symptoms potentially holds promise for individuals with darker skin tones. More research focusing on potential variations in skin physiology across different racial groups is essential to establish more effective diagnostic schemes applicable to both dark and light skin colors.

A survey on the real-world clinical utilization of a traditional acupuncture in Republic of Korea: Sa-am acupuncture.

OBJECTIVE: This study investigated the clinical details and usage of Sa-am acupuncture in Korean medicine clinics and explored how practicing Korean medicine doctors (KMDs) think about Sa-am acupuncture. METHODS: We conducted a questionnaire-based survey of KMDs who utilize Sa-am acupuncture in their practice. The study comprehensively investigated issues related to clinical application of Sa-am acupuncture, needling techniques used during treatment, training methods, and directions for its future improvement. RESULTS: We analyzed 572 responses. An average of 50% of the patients visiting Korean medicine clinics were receiving Sa-am acupuncture. The most prevalent indication for Sa-am acupuncture use was digestive disorders. The patients' appetite level and digestive function were most frequently used indicators for selecting acupuncture points. Regarding prescription compositions, Jung-Gyuk formulas were more frequently used than Seung-Gyuk formulas. Inserting the needle along the flow of the channel or against the flow of the channel was most popular. The acupuncture style most frequently used in combination with Sa-am acupuncture was Ashi point acupuncture. Strengths of Sa-am acupuncture included its versatility, easy application, and good outcomes. Limitations included the lack of rigorous education and training programs, difficulty in applying the principles for beginners, and insufficient clinical research evidence. CONCLUSION: In clinics where Sa-am acupuncture is available, KMDs were providing Sa-am acupuncture to about half of their patients. Practitioners were not using all of the tonification and sedation techniques which may be due to time constraints or simply a lack of necessity. Sa-am acupuncture demonstrated high utility in clinical practice and high satisfaction based on the efficacy and safety. More training programs and high-quality research are needed to help expand the use of Sa-am acupuncture. Please cite this article as: Park JY, Lee YS, Park HJ, Lee SK, Lee JW, Kim SY.
