Introduction : Attention-Deficit/Hyperactivity Disorder (ADHD) is a disorder that occurs during childhood development, which presents with signs of reduced attention and hyperactivity [1]. Necessary nutrients, such as trace minerals, including manganese, iron, zinc, iodine, selenium, copper, and chromium, are associated with changes in neuronal function that can lead to adverse effects on behavior and learning [2]. In addition to these, social, emotional, behavioral problems, and cognitive impairments such as executive dysfunctions are common in ADHD [3]. Goal: To evaluate the hair elements and intelligence quotient in children with ADHD. Materials and Methods: This is a cross-sectional comparative study conducted at elementary schools of Ulaanbaatar city. All in all 60 children of both genders aged between 7-12 years old were included in the study. Children were divided into two groups as children with ADHD group and a control group. Each group had 30 children. For assessment of emotional Intelligence EQ-i:YV - Emotional Quotient Inventory: Youth Version (Bar-On & Parker, 2000; it ad. Sannio Fancello, & Cianchetti, 2012) was used. Scalp hair samples were randomly collected from approximately ten sites around both sides of posterior parietal eminences and external occipital protuberance. Samples were then packed at room temperature and submitted for laboratory analysis. The study was approved by the Research Ethics Committee of Mongolian National University of Medical Sciences (Reg. No. 2018/Д-10). Results: The IQ of children with ADHD group were 85.03±16.86 p<.0001 and the IQ of control group =108.9±21.22, p<.0001. We identified hair minerals such as Mg, Zn, Pb, Se, Mn. We have then compared to each group and normal ranges of ages. ADHD group and the control group had Pb concentration that was slightly higher and inversely Mg concentration was slightly lower (r=-0.502, p=.005). Concentration of Pb, IQ were directly opposite (r=-0.38, p=.03). Conclusion
1. IQ was lower in the ADHD group compared to control group 85.03±16.86 p<.0001, monitored group 108.9±21.22, p<.0001.
2. The group with ADHD had lower Mg, Zn, and higher Pb, Se, Mn (p<.0001). The IQ decreased when there was increased Pb and decreased Mg.

Background: Accreditation of healthcare institutions serves as a fundamental mechanism for ensuring patient safety and validating the quality of medical services provided to the population. At Intermed Hospital, a quality measurement system for healthcare services has been established since 2015, encompassing 126 quality indicators at both institutional and departmental levels. This system facilitates continuous quality improvement efforts. In this context, quality indicators specific to the endoscopy department play a pivotal role in objectively assessing the quality of endoscopic services. Aim: To assess the quality indicators in gastrointestinal endoscopy unit. Materials and Methods: A retrospective single-center study was conducted by collecting data from the Intermed hospital’s electronic information systems which included HIS and PACS and Quality and Safety Department’s Database and the results were processed using the SPSS software. Ethical approval was granted by the Intermed hospital’s Scientific research committee. The quality of endoscopic services in the Intermed hospital was assessed based on: a) the average values of four quality indicators measured monthly; b) sample survey data from five categories of quality indicators. Results : Between 2016 and 2024, the quality indicators of the endoscopy unit measured as the level of early warning score evaluations for patients was 95.97%±3.33, the level of cases where peripheral blood oxygen saturation decreased during sedation was 1.54%±3.78, the level of cases where patients experienced paradoxiical response during sedation was 5.82%±1.75, surveillance culturing level for validation of endoscopy reprocessing was 11.6%. The endoscopic documentation quality by peer review showed 95.7-100%, the colonoscopy quality indicators were followings as adenoma detection rate: 24.5% Cecal intubation rate: 99.1%, 95.2%, Colonoscope withdrawal average time: 13.28±10.62 minutes, Bowel preparation quality (Boston Scale): 89.3% 95.7%), patient discharge from the recovery room, Average discharge time post-procedure: With propofol alone: 30.92 minutes; With propofol and fentanyl combined: 31.52 minutes, The intermediate risk was 0.28% by the TROOPS evaluation during procedural sedation. Conclusion The quality benchmark levels for these endoscopic units, as determined by a single-center study, can be effectively implemented by benchmark endoscopy centers to enhance their quality and safety operations.
