Tai Chi, a traditional Chinese martial art characterized by gentle, fluid movements and deep breathing, has gained increasing recognition for its cardiovascular health benefits. This study investigated the integration of Tai Chi into contemporary cardiovascular health practices, focusing on its physiological and psychological effects. The slow, controlled movements characteristic of Tai Chi contribute to enhanced cardiovascular fitness, decreased blood pressure, and improved vascular function, while simultaneously alleviating stress and fostering emotional well-being. Through a review of clinical studies and trials, this study underscores the efficacy of Tai Chi in cardiovascular rehabilitation programs and its accessibility as a community-based intervention. Additionally, this study addresses obstacles to widespread adoption, including cultural barriers and the lack of standardized training for instructors. By integrating traditional practices with contemporary medical approaches, Tai Chi is as a valuable complementary therapy for cardiovascular health. The paper presents future research directions and advocacy strategies aimed at promoting broader acceptance and implementation of Tai Chi in health-care settings. This review underscores the continued relevance of Tai Chi as an effective intervention for cardiovascular wellness in modern therapeutic contexts.

Emerging evidence reveals that circadian rhythm, melatonin signaling, nutrition, and inflammation are intricately intertwined in shaping both mental and physical health. Circadian disruptions and lifestyle imbalances contribute to neuroinflammation, mood dysregulation, and cardiometabolic dysfunction, as seen in attention-deficit/hyperactivity disorder (ADHD), major depressive disorder (MDD), metabolic syndrome, and cardiovascular diseases. This special issue highlights interdisciplinary research that integrates circadian biology, nutrition, and psychoneuroimmunology (PNI) toward personalized and preventive psychiatry. Featured studies explore circadian and melatonin mechanisms in ADHD and MDD, the therapeutic and prophylactic potential of omega-3 polyunsaturated fatty acids (n-3 PUFAs), the neuroprotective potentical of paeoniflorin, and the role of extracellular matrix gene variants in MDD vulnerability. Additionally, evidence supporting lifestyle-based interventions such as Tai Chi underscores the value of non-pharmacological mind-body approaches. Collectively, these studies illuminate a multidimensional model linking biological rhythm, nutrition, and inflammation to mental resilience and cardiovascular well-being.

Dysregulation of extracellular matrix (ECM) degradation pathways has been increasingly implicated in major depressive disorder (MDD), yet its genetic basis remains unclear. This study investigated the relationship between ECM-related genetic polymorphisms and MDD susceptibility. In a case-control study, we analyzed 317 MDD patients and 1268 sexmatched controls from the Taiwan Biobank (TWB). Genomic DNA was analyzed using the Affymetrix TWB array, targeting single nucleotide polymorphisms (SNPs) in 140 ECM degradation genes (Reactome database). Full-model association tests identified significant SNPs, validated with 5000 max(T) permutations and adjusted via logistic regression for age, body mass index, education level, and marital status. We identified 12 SNPs across 10 ECMrelated genes significantly associated with MDD, including ADAM metallopeptidase domain 17 (ADAM17, rs55820761), brevican (BCAN, rs11264511), CD44 molecule (CD44, rs12270356), collagen type XVII alpha 1 chain (COL17A1; rs2282436 and rs10883962), collagen type III alpha 1 chain (COL3A1; rs16830979 and rs10883962), collagen type VI alpha 6 chain (COL6A6, rs16830219), cathepsin L (CTSL, rs2274611), Kallikrein-related peptidase 2 (KLK2, rs2664156), matrix metallopeptidase 11 (MMP11, rs738791), and nicastrin (NCSTN, rs3753391). This study provides the first genetic evidence linking ECM degradation pathways to MDD susceptibility, identifying novel biomarkers for early diagnosis and precision therapy. Further research and cross-population studies are needed to confirm these findings.

Attention-deficit hyperactivity disorder (ADHD) is a common neurodevelopmental condition often accompanied by circadian rhythm disturbances, particularly delayed sleep phase. These involve suprachiasmatic nucleus (SCN) dysregulation, altered melatonin secretion, and hypothalamic-pituitary-adrenal (HPA) axis activity, which may be exacerbated by artificial light exposure. Genetic studies further implicate circadian mechanisms, linking ADHD with polymorphisms in clock genes such as PER and CLOCK. Nutraceuticals, particularly omega-3 polyunsaturated fatty acids (n-3 PUFAs), have been proposed as modulators of circadian rhythms. N-3 PUFAs are essential for brain health and may influence melatonin synthesis and sleep-wake regulation. Preclinical and clinical findings suggest that supplementation can improve cognitive and behavioral outcomes in ADHD, possibly through circadian pathways, though direct clinical evidence remains limited. This review integrates findings on melatonin and cortisol dysregulation in ADHD and evaluates n-3 PUFAs as potential non-photic zeitgebers. N-3 PUFAs may modulate circadian clock genes in the SCN, restore rhythm synchronization, normalize melatonin secretion, stabilize HPA axis activity, and reduce systemic inflammation. Future research should focus on well-designed trials to clarify the circadian effects of n-3 supplementation in ADHD.

Background: Omega-3 polyunsaturated fatty acids (n-3 PUFAs) have demonstrated efficacy as adjunctive treatment for MDD. In fact, fewer studies assessed the prophylactic properties of n-3 PUFAs as monotherapy on the recurrence of MDD.

Aims: This study aimed to assess the prophylactic effect of n-3 PUFAs monotherapy against recurrent MDD.

Methods: We conducted a 6-month randomized controlled trial to assess the prophylactic effect of n-3 in preventing recurrent MDD. We assigned 60 remitted MDD patients to the n-3 group (n = 30) and placebo (n = 30). Furthermore, we assessed the difference in depression severity and MDD recurrence based on the 21-item Hamilton Rating Scale for Depression (HRSD) at months 1, 2, 3, 4, and 6 between groups. The recurrent event of MDD was defined as an HRSD score >20. Furthermore, biochemical parameters in plasma were assessed as the secondary outcomes.

Results: There was no significant difference in the HRSD score between the n-3 group and placebo each month ( p-value >0.05). However, our findings have implicated that omega-3 monotherapy for MDD contributed to a lower recurrence rate compared to the placebo group at month 6 ( p-value = 0.035). Omega-3 supplementation was superior to placebo to preventing recurrent MDD analyzed using Kaplan-Meier survival analysis over a 6-month study period ( p-value = 0.041). In comparison, the eicosapentaenoic acid (EPA) plasma level of the n-3 group at the end point of study was significantly higher than the placebo ( p-value = 0.023), but not for docosahexaenoic acid (DHA) ( p-value = 0.119).

Conclusion: Our study concluded that n-3 PUFAs monotherapy demonstrated a prophylactic effect on the recurrence of MDD.

Prolonged exposure to inorganic arsenic is commonly linked to brain damage via oxidative and apoptotic processes. The compound garcinol (GCL) has garnered significant interest because of its beneficial effects on human health. However, the protective ability of GCL against arsenic-induced toxicity in the brain remains unexplored. Therefore, our study aimed to examine the neuroprotective effect of GCL against the adverse impact of sodium arsenite (SA) on behavioral patterns, molecular mechanisms, apoptotic markers, and oxidative stress parameters in the brain, liver, and kidneys of mice. The mice were categorized into four distinct groups for 28 days: Group I, referred to as the Control group, received a 5 % v/v solution of dimethyl sulfoxide (DMSO); Group II, referred to as the SA group, received a dosage of 20 mg/kg of SA; Group III, referred to as the SA + GCL group, received a combined dosage of 20 mg/kg of SA and 50 mg/kg of GCL; and Group IV, referred to as the GCL group, received a dosage of 50 mg/kg of GCL. Following drug administration, the behavior of the animals was evaluated and analyzed. Additionally, the levels of acetylcholinesterase (AChE), ATP hydrolysis, and angiotensin I-converting enzyme (ACE), which are associated with cognitive function, were examined. Our study demonstrated that the administration of GCL enhanced cognitive behavior. Additionally, GCL mitigated cholinergic deficits as evidenced by a reduction in AChE activity. Furthermore, GCL increased the signaling of glycogen synthase kinase 3 beta (GSK3β) and cAMP response element-binding protein (CREB) in SA-treated mice, enhanced redox equilibrium, and protected against oxidative damage caused by SA in the brains of mice. This effect was mediated by the activation of nuclear factor erythroid 2-related factor 2 (NRF2)/heme oxygenase-1 (HO-1) proteins, resulting in a significant decrease in malondialdehyde concentration. Thus, this preclinical study showed that treatment with GCL ameliorated neurobehavior, modulated cognitive function-associated biomarkers, and protected mice from SA-induced neurotoxicity.

We report the case of a 70-year-old woman who sustained complex traumatic injuries in a motor vehicle accident, including cervical spine fractures and a high suspicion of traumatic vertebral artery injury (VAI). Initial digital subtraction angiography (DSA) revealed no evidence of vertebral artery (VA) involvement. She subsequently underwent anterior cervical discectomy and fusion (ACDF); however, an iatrogenic injury to the right VA occurred intra-operatively, necessitating emergent endovascular stenting for vascular repair. This case underscores the importance of comprehensive preoperative imaging, intraoperative vigilance, and coordinated multidisciplinary management in cervical spine trauma with potential vascular involvement.

Renal duplication anomalies are one of the most frequent congenital urological conditions in the general population all over the world. Bilateral incomplete duplication, however, is exceedingly rare. We present a case of a 29-year-old female with bilateral incomplete duplex kidneys complicated by mid-ureteric stenosis on the right side and calculi in the left ureter and upper moiety of the left duplex kidney. Diagnostic imaging, including ultrasound, computed tomography (CT), and intravenous urography (IVU) confirmed these findings. The patient underwent successful bilateral ureteroscopy (URS) and left-sided retrograde intra-renal surgery (RIRS) for management of the above mentioned complications related to the duplex kidneys in this patient. Postoperative recovery was uneventful, and a further right-sided percutaneous nephrolithotomy (PCNL) was planned. This case underscores the importance of comprehensive diagnostic evaluation and individualized therapeutic strategies in managing complex urological anomalies.

Background: The aim of this cohort study was to investigate the association between hyperthyroidism and the likelihood of developing herpes zoster in Taiwan.

Methods: Using the National Health Insurance Research Database (NHIRD) in Taiwan, we selected individuals aged 20-84 who were newly diagnosed with hyperthyroidism between 2013 and 2020 as the hyperthyroidism group. These individuals were then matched with a control group without hyperthyroidism in a 1:1 propensity score matching for sex, age, and baseline comorbidities. The occurrence of herpes zoster was tracked in both groups until the end of the study period or until a diagnosis of herpes zoster was made. The Cox proportional hazards regression analysis was used to determine the hazard ratio (HR) and 95 % confidence interval (CI) for the risk of herpes zoster associated with hyperthyroidism.

Results: A total of 202,069 individuals with hyperthyroidism and 202,069 individuals without hyperthyroidism were included in the analysis. The incidence rate of herpes zoster was higher in the hyperthyroidism group compared to the non-hyperthyroidism group (6.10 per 1000 person-years for the hyperthyroidism group versus 5.53 per 1000 person-years for the non-hyperthyroidism group, incidence rate ratio = 1.10, 95 %CI = 1.07-1.14, and P value < 0.001). After adjusting for covariables, individuals with hyperthyroidism were found to have a higher risk of developing herpes zoster compared to those in the non-hyperthyroidism group (adjusted HR = 1.19, 95 %CI = 1.15-1.23, and P < 0.001).

Conclusion: This cohort study suggests that individuals with hyperthyroidism in Taiwan may have a greater risk of developing herpes zoster compared to those without hyperthyroidism.

Cancer poses a significant burden on global public health, contributing to high mortality rates worldwide. Ongoing diagnostic strategies have predominantly relied on imaging techniques, histopathological examination and molecular analyses which have limitations in sensitivity, and specificity. Early cancer detection is a pivotal determinant of successful treatment and patient survival rates. Metabolomic applications involve the comprehensive analysis of metabolites to understand the metabolic profile of an organism, tissue, or cell under different conditions such as lack of oxygen in tumors. The aim of this review is to provide an extensive approach of metabolomic applications in early cancer detection and to provide an overview of the strengths and limitations of metabolomic approaches in early cancer detection. Metabolomic profiling can identify specific metabolic biomarkers indicative of early-stage cancer. The identification of these biomarkers can lead to development of non-invasive diagnostic tests which can be used for early cancer screening. Several researchers have already employed the metabolomics approach for biomarker discovery, diagnosis, identifying new drug targets along with the clinical trials observations. When discussing challenges, researchers currently face a notable obstacle, the absence of standardized analytical procedures. It is imperative for the field to prioritize implementing computational tools for constructing open-source databases, thereby advancing metabolomic studies in cancer research.
