Background: Insomnia is one of the most prevalent neurological disorders in the United States, affecting up to half of primary care patients and often necessitating psycho-behavioral interventions. Acupuncture, a key component of traditional Chinese and Mongolian medicine, has been increasingly studied as a treatment for insomnia in recent years. Aim: Evaluating the effectiveness of acupuncture for insomnia Materials and Methods: The study was conducted using a randomized controlled clinical trial design. 148 participants, aged 18-65 years, with a diagnosis of Nonorganic Insomnia (F51.0) according to the ICD-10, and Pittsburgh Sleep Quality Index (PSQI) >7, were divided into the transverse acupuncture, conventional acupuncture, and the control group. The results were analyzed using a Cardiopulmonary Coupling - CPC machine before and after treatment in the 3 groups to assess 1. Total sleep (hours), 2. Deep sleep (hours), 3. Light sleep (hours), 4. REM (hours), 5. Wake time (minutes), 6. Time to first fall asleep (minutes), 7. Sleep rate (%), 8. Number of apneas, and sleep quality was assessed using the Insomnia Severity Index (ISI) and Pittsburgh Sleep Quality Index (PSQI) questionnaires. The research approval was reviewed and granted by the Research Ethics Review Committee of the Mongolian National University of Medical Sciences on January 19, 2024 (Approval No. 24/19/01). Results: The mean age of participants was 51.5±10.8 years, with 79.7% (n=118) being female and 20.3% (n=30) male. In the transverse acupuncture group, post-treatment results demonstrated a 53.8% increase in total sleep time, a 102.8% increase in deep sleep time, a 19.8% increase in light sleep time, a 36.1% increase in REM sleep time, and a 22.1% improvement in sleep normalization rate. The mean differences between pre- and post-treatment scores were statistically significant based on a one-sample t-test. In contrast, no statistically significant improvements were observed in the control group, except for sleep quality. Conclusion Both transverse acupuncture and conventional acupuncture significantly improved sleep quality indicators following treatment.

Background: Musculoskeletal disorders account for 23.1-47.1% of occupational diseases in several countries. Studies have shown that operators of heavy machinery, including tractors and dump trucks, are twice as likely to experience lower back pain compared to workers not exposed to whole-body vibration. Furthermore, research has indicated that acute exposure to vibration can cause vasoconstriction and vascular inflammation. However, limited research has explored the relationship between lower back pain and specific biomarkers, highlighting the need for this study. Aim: This study aimed to compare lower back pain prevalence and muscle inflammation biomarkers among heavy machinery operators. Materials and Methods: A purposive sampling method was used to recruit 15 male participants aged 25-35 years who had worked as heavy machinery drivers for no more than three years. Inclusion criteria were: no alcohol consumption within 24 hours prior to sampling, body mass index (BMI) between 18.5-28.9 kg/m², no prior diagnosis of musculoskeletal disorders, and absence of infectious or non-infectious diseases during the study period. Blood samples were analyzed for Interleukin-6 (IL-6) and Tumor Necrosis Factor-alpha (TNF-α) levels using enzyme-linked immunosorbent assay (ELISA). Results: The mean BMI of participants was 25.89±3.23 kg/m². Over half (53.3%, n=8) exceeded the exposure limit for whole-body vibration. Low back pain was reported by 13 participants (86.7%) over the past six months and by 12 participants (80%) over the past seven days. TNF-α levels did not differ significantly between groups based on low back pain status or vibration exposure. However, IL-6 levels showed a significant increase 24 hours after whole-body vibration exposure (p=0.027). Conclusion Lower back pain was highly prevalent among participants exposed to whole-body vibration. Furthermore, IL-6 levels were elevated among participants reporting lower back pain, regardless of vibration exposure levels.
