Background. Existing literature suggests that an association exists between coronary artery disease (CAD) and carpal tunnel syndrome (CTS), but few researchers have explored whether CTS is a risk for CAD. Materials and Methods. This large case-control study explored the association between CTS and CAD, using health insurance claims data from Taiwan’s National Health Insurance Research Database (NHIRD) between January 2000 and December 2013. International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) diagnostic codes identified 70,622 patients with CAD (ICD-9-CM codes 410–414; cases); 70,622 patients without CAD were frequency-matched by age, sex, and index year of CAD and served as controls. Results. The likelihood of a previous diagnosis of CTS (ICD-9-CM codes 354.0, 354.1) was significantly higher in the CAD group than in the comparison control group (crude OR: 1.75, 95% CI 1.63-1.89; p<0.0001; adjusted OR: 1.46, 95% CI 1.34-1.58; p<0.0001). Conclusion. A significant positive correlation was observed between CAD and a previous diagnosis of CTS.

Laser acupuncture (LA) has been more applicated in the clinical practice with good responses, but the dosage and parameter settings are still inconsistent with the arguments. This study is focused on the effect of LA on heart rate variability (HRV) with different energy density (ED). Based on the Arndt–Schulz law, we hypothesized that the effective range should fall within 0.01 to 10 J/cm2 of ED, and settings above 10 J/cm2 would perform opposite or inhibitory results. We recruited healthy adults in both sexes as subjects and choose bilateral PC6 (Neiguan) as the intervention points to observe the HRV indexes changes by an external wrist autonomic nerve system (ANS) watch on the left forearm. The data from the ANS watch, including heart rate, blood pressure, and ANS activity indexes, such as low frequency (LF), high frequency (HF), LF%, HF%, LF/HF ratio, and so on, were analyzed by the one-way ANOVA method to test the possible effect. In this study, every subject received all three different EDs of LA in a randomized order. After analyzing the data of 20 subjects, the index of HF% was upward and LF/HF ratio was downward when the ED was 7.96 J/cm2. Otherwise, the strongest ED 23.87 J/cm2 performed the opposite reaction. Appropriately, LA intervention could affect the ANS activities, with the tendency to increase the ratio of parasympathetic and decrease the ratio of sympathetic nerve system activities with statistically significant results, and different ED interventions are consistent with Arndt–Schulz law with opposite performance below and above 10 J/cm2.

Chronic pelvic pain (CPP) is the pain occurred in the pelvic region longer than six months. The monotherapy of medicine may not adequate for the pain management of CPP and multidisciplinary approaches have been more recommended. The aim of this study is to evaluate the pain management efficacy of acupuncture compared with a control group on CPP. The articles of randomized controlled trial on CPP in PubMed and Embase databases were screened between January 2011 and September 2022 without language restriction to evaluate the treatment efficacy of acupuncture. The visual analogue scale/numerical rating scale (VAS/NRS) and total pain scores of National Institutes of Health—chronic prostatitis symptom index (NIH-CPSI) were served as outcome variables. Post-intervention mean scores were extracted and pooled for meta-analysis. Seventeen studies including 1455 patients were selected for meta-analysis. Both total pain scores of NIH-CPSI and VAS/NAS data revealed significant lower pain level in the acupuncture group than in the control group. Moreover, monotherapy with acupuncture revealed a significantly lower pain level than in the control group in both total pain scores of NIH-CPSI and VAS/NRS. These results indicated that acupuncture may have beneficial effects on pain management for CPP, even when administrated as a monotherapy.
