Background: Leptopyrum fumarioides (L.) Reichenb a relatively widely distributed annual herbaceous plant belonging to the Ranunculaceae family, grows predominantly in the dry steppe regions of Mongolia. In recent years, the global use of traditional medicine and natural products has increased substantially. In this context, elemental studies of medicinal plants including macroelements, microelements, and heavy metals provide a fundamental scientific basis for evaluating their nutritional value, therapeutic efficacy, safety, and standardization. Therefore, the investigation of the elemental composition of Leptopyrum fumarioides (L.) Reichenb is of significant importance as a foundational study supporting its medicinal application. Aim: To investigate the chemical elements, present in Leptopyrum fumarioides (L.) Reichenb. Objectives: 1. To prepare plant samples and determine the contents of aluminum oxide, silicon dioxide, iron oxides, and calcium oxide in the plant material. 2. To identify and quantify the mineral elements present in the plant material. 3. To investigate the heavy metals in the plant material. Materials and Methods: Leptopyrum fumarioides (L.) Reichenb were collected from Altanbulag soum, Töv Province, Mongolia, during the flowering stage in June 2023. The collected plant materials were air dried in accordance with standard procedures and used for analysis. The quantitative contents of macroelements, microelements, and ultra-trace elements in the plant were determined using high precision X ray fluorescence (XRF) analysis. Result: In the raw plant material of Leptopyrum fumarioides (L.) Reichenb, the silicon dioxide (SiO₂) content was 15.99%, which increased to 33.69% in the extracted residue. Titanium dioxide (TiO₂) was present at 0.16% in the raw material and 0.379% in the plant residue. Aluminum oxide (Al₂O₃) was 3.54% in the raw material and 7.52% in the extracted residue. Iron oxide (Fe₂O₃) was 1.14% in the raw material and 2.51% in the residue. Other oxides, including calcium oxide (CaO), potassium oxide (K₂O), and phosphorus pentoxide (P₂O₅), remained in the extracts. The concentrations of trace elements in the plant were determined as follows: copper (Cu) 40.5 mg/kg, zinc (Zn) 211 mg/kg, chromium (Cr) 8.5 mg/kg, and nickel (Ni) 8 mg/kg. The levels of Zn (211 mg/kg) and Cu (40.5 mg/kg) were found to be relatively higher compared to those reported in other plant species. Conclusion 1. In the raw plant material of Leptopyrum fumarioides (L.) Reichenb, silicon dioxide (SiO₂) content was 15.99%, increasing to 33.69% in the extracted residue. Titanium dioxide (TiO₂) was 0.16% in the raw material and 0.379% in the residue. Aluminum oxide (Al₂O₃) was 3.54% in the raw material and 7.52% in the extracted residue. Iron oxide (Fe₂O₃) was 1.14% in the raw material and 2.51% in the residue. Other oxides, including calcium oxide (CaO), potassium oxide (K₂O), and phosphorus pentoxide (P₂O₅), were retained in the extracts. 2. The trace element analysis revealed the following concentrations: copper (Cu) 40.5 mg/kg, zinc (Zn) 211 mg/kg, chromium (Cr) 8.5 mg/kg, and nickel (Ni) 8 mg/kg. The levels of Zn (211 mg/kg) and Cu (40.5 mg/kg) were higher than those typically found in most plants; however, these concentrations are below the threshold considered toxic to plant physiology. Rubidium (Rb) at 49 mg/kg and zirconium (Zr) at 69 mg/kg were also relatively high compared to other elements. This may be related to the ability of Leptopyrum fumarioides (L.) Reichenb to accumulate certain elements when growing in moderately contaminated soils near cultivated fields. 3. Rare earth elements, such as cerium (Ce) and ytterbium (Yb), were found to be below the general concentration range and can be considered within normal limits. Furthermore, the plant contains numerous trace elements that participate in various enzymatic activities and contribute to the components of the blood coagulation system.

Background: Developing a standardized methodology and a reliable and valid assessment tool for assessing the professional competence of nurses in Mongolia is of great importance for nursing research and practice. Aim: To determine the psychometric properties of the Mongolian version of the Competency Inventory for Registered Nurses. Materials and Methods: This study was conducted using a methodological research design. The study included 550 nurses from 11 state hospitals and collected data between June and December 2024 using the Competency Inventory for Registered Nurses Scale (CIRN) developed by Ming Liu et al. (2007). Result: The internal reliability of the questionnaire was Cronbach’s alpha coefficient (Cronbach’s α=0.98). Content validity indices (Content Validity Index CVI) were I-CVI ≥ 0.78, S-CVI/Ave=0.98, and S-CVI/UA=0.85, indicating good content validity. Varimax factor analysis revealed factor loadings ranging from 0.380 to 0.780. Conclusion 1. The Mongolian version of the Competency Inventory Registered Nurses demonstrated adequate internal reliability. 2. The validity of the questionnaire was confirmed to be acceptable.

Background: Pulmonary alveolar proteinosis (PAP) is a rare lung disorder characterized by the accumulation of surfactant within the alveoli, leading to impaired gas exchange and respiratory insufficiency. Although the disease is uncommon, it significantly affects patients’ quality of life and requires specific diagnostic and therapeutic approaches. Whole lung lavage (WLL) is considered the standard treatment; however, it has not been widely implemented in Mongolia. We report the first successful case of WLL performed for PAP in Mongolia. Case Presentation: A 56-year-old male presented with dyspnea. Chest computed tomography demonstrated a bilateral “crazy paving” pattern. Bronchoalveolar lavage fluid was positive for periodic acid–Schiff (PAS) staining, and anti–GM-CSF antibodies were detected, confirming the diagnosis of PAP. WLL was performed under general anesthesia using a double-lumen endotracheal tube with bronchoscopic guidance. One lung was ventilated with 100% oxygen while the contralateral lung was sequentially lavaged with 800–1000 mL of warm (37°C) saline per cycle until the effluent became clear. A total of approximately 20 liters of saline was used. Result: The procedure was completed successfully without complications. Following treatment, the patient showed marked clinical improvement with reduced dyspnea and increased exercise tolerance. Oxygen saturation improved from 88% to 93%, and spirometric parameters (FVC, FEV₁) demonstrated improvement. Chest imaging revealed a reduction in pulmonary opacities. Conclusion This case demonstrates the successful implementation of whole lung lavage (WLL) in Mongolia and highlights its importance in improving the diagnostic and therapeutic capacity for rare pulmonary diseases such as pulmonary alveolar proteinosis. The procedure resulted in significant improvement in clinical, functional, and radiological parameters, consistent with findings from international studies. Early diagnosis of PAP and the adoption of standardized protocols in accordance with international guidelines are essential to optimize treatment outcomes and enhance patients’ quality of life.

Background: Nursing theories help nurses understand the values and beliefs related to human health and support them in providing effective and compassionate care to patients. Nursing theorist Jean Watson defined the relationship between nurses, patients, and their families as an interpersonal interaction, referring to it as a “transpersonal caring relationship.” Currently, there is a lack of studies based on Jean Watson’s theory that examine how nurses’ attitudes and behaviors influence the quality of life of patients undergoing hemodialysis. Therefore, this topic was selected for the present study. Aim: To determine how nurse–patient interaction influences patients undergoing hemodialysis based on Jean Watson’s Theory of Human Caring. Materials and Methods: A cross-sectional study design was employed using a quantitative survey method. The study included 72 patients undergoing hemodialysis at Medvic Hospital. The Caring Nurse–Patient Interaction Scale (CNPI-70P), patient version, was used to assess attitudes and behaviors in nurse–patient interactions. This instrument was originally developed by Sylvie Cossette in 2005. Official permission to use the patient version of the questionnaire was obtained from the author on March 29, 2023. Data collection was conducted between December 2025 and January 2026. Statistical analysis was performed using SPSS version 25. Descriptive statistics were used to analyze subscales, independent sample t-tests were applied to compare group differences, and Pearson correlation analysis was conducted to determine relationships among variables. Results: The mean age of the participants was 38.8±10.5 years, with a mean age of 39.3 years for males and 38.1 years for females. The overall evaluation of nurse–patient interaction in nursing care among patients undergoing hemodialysis was at a moderate level (3.78±0.82). There was no statistically significant difference between the mean ages of the two groups (t (70) =0.494, p=0.623). The reliability of the CNPI-70 questionnaire was very high, with a Cronbach’s alpha of 0.988. Among the subscales, the highest score was observed for “meeting human needs” (M=4.16, SD=0.87), indicating that nurses most frequently supported patients in fulfilling their needs. High scores were also observed for “humanism” (M=4.02, SD=0.80) and “helping relationship” (M=4.00, SD=0.86). In contrast, the lowest score was found for “sensitivity” (M=3.39, SD=1.13), followed by “spirituality” (M=3.47, SD=0.99) and “problem-solving” (M=3.56, SD=1.07), indicating comparatively lower levels in these aspects. The mean scores of the remaining factors ranged from 3.72 to 3.95. Conclusion Nurse–patient interaction among patients undergoing hemodialysis was found to be at a moderate level (3.78±0.82). However, aspects related to understanding patients’ sensitivity, providing emotional support, and meeting spiritual or psychological needs were relatively lower.

Background: Between 2017 and 2021, the prevalence of obesity among children aged 2-19 years reached 19.7%, affecting approximately 14.7 million children, with rates of 12.7% among those aged 2-5 years and 22.2% among those aged 6-11 years. Globally, dental caries is among the most common non-communicable diseases, often leading to pain, infection, tooth loss, and reduced quality of life. In Mongolia, the prevalence of overweight and obesity among children and adolescents has increased markedly since 2010, beginning at an early age. In 2018, one in six children under five years and one in eight adolescents were overweight. Aim: This study aimed to assess selected non-communicable disease risk factors among children and adolescents. Materials and Methods: A cross-sectional study was conducted in Ulaanbaatar, Mongolia, using Family Health Centers across all nine districts. A total of 622 children aged 6–17 years were included. Anthropometric measurements (weight, height, and waist circumference) were obtained, and body mass index (BMI) was calculated. Oral health examinations were performed to determine the Decayed, Missing, and Filled Teeth (DMFT) index. Nutritional status was classified based on age and sex-specific growth charts into normal weight, overweight, and obesity categories. Results: Among the participants, 10.29% (n=64) were overweight and 9.97% (n=62) were obese. Overweight was more prevalent among girls, whereas obesity was relatively higher among boys (p<0.001). Regarding dental caries, 37.6% (n=234) of participants had no caries (DMFT=0), 48.1% (n=299) had mild caries (DMFT=1-2), and 14.3% had moderate to severe caries (DMFT≥3). The overall prevalence of dental caries was 62.38%, with significant variation by age group: highest in children aged 6-9 years (69.9%) and lowest in those aged 15-17 years (46.1%) (p<0.001). No statistically significant association was found between BMI categories and dental caries status. Although normal weight predominated in the DMFT=0 and DMFT=1-2 groups, logistic regression adjusted for age and sex showed no significant relationship between BMI and dental caries. However, children aged 6-9 years had a significantly higher likelihood of having dental caries compared to those aged 15-17 years (OR=0.39, 95% CI: 0.24-0.63, p<0.001). Conclusions 1. Among the risk factors for non-communicable diseases (NCDs), overweight and obesity were highly prevalent among children, with one in every five children classified as overweight or obese. The prevalence among male children was approximately two times higher than that among female children (p<0.001). 2. The prevalence of dental caries among the study participants was 90.7%, with a mean caries intensity of 6.4, indicating high level of severity. Age-group analysis demonstrated that children aged 6–10 years exhibited the highest prevalence and severity of dental caries, with a prevalence of 93.5% and a mean caries intensity of 7.3.

Background: Teaching is a profession associated with high levels of stress. Research has shown that when job demands are high while organizational support is insufficient, levels of stress and burnout increase. Aim: Prior to conducting our study aimed at determining the stress levels among university faculty members, we performed a literature review. Materials and Methods: We conducted a literature search using the PubMed and Embase databases for studies published in English without restriction on publication year, including all relevant articles available up to September 2025. The search strategy included the following keywords: “stress,” “researchers,” “university professors,” “academic researchers,” “college,” “academics,” “scholars,” “teachers,” and “professors.” Results: We searched for English-language publications in the PubMed and Embase databases without year restrictions, including studies published up to September 2025. The search was conducted using the following mesh terms: “stress,” “researchers,” “university professors,” “academic researchers,” “college,” “academics,” “scholars,” “teachers,” and “professors.” A total of 3,961 articles were identified from the database search. After screening titles, 2,944 articles were excluded. Subsequently, 58 articles were reviewed based on their abstracts, and 12 studies that were relevant to our research objectives and questionnaire were selected for analysis. Conclusion This review study demonstrated that stress levels among university and college faculty members are high. Stress is associated with multiple factors, including workload, organizational support, and performance demands, leading to negative physical and psychological consequences. Therefore, it is necessary to implement systematic institutional-level interventions to support the well-being of faculty members.

Background: Pulmonary embolism (PE) is a potentially life-threatening condition. Although advances in diagnostic and risk-stratification tools have reduced acute mortality, few studies have evaluated its impact on quality of life after diagnosis. Aim: To assess health-related quality of life in patients with acute PE during hospitalization and three months after diagnosis using the PEmb-QoL questionnaire. Materials and Methods: This prospective longitudinal cohort study included 83 patients with acute PE who completed the PEmb-QoL questionnaire during hospitalization and at three-month follow-up. Six domains were assessed: symptom frequency, activities of daily living, work-related problems, social limitations, symptom intensity, and emotional complaints. Scores were transformed to a 0–100 scale, with higher scores indicating poorer quality of life. Statistical analyses were performed using SPSS 26.0. Paired scores were compared using the Wilcoxon signed rank test, and Spearman's correlation was used to assess associations with clinical severity indices. A linear mixed-effects model including PESI, sPESI, and age assessed whether hospitalization PEmb-QoL scores predicted three-month outcomes. The study protocol was approved by the Research Ethics Committee of the Mongolian National University of Medical Sciences (Approval No. 24/-25/10-1, June 12, 2025), and written informed consent was obtained from all participants prior to enrollment. Results: Mean age was 62.06 ± 17.5 years, and 46.4% of participants were male. Mean scores improved across all six domains at three months. Significant improvements were observed in symptom frequency, work-related problems, social limitations, symptom intensity, and emotional complaints (all p<0.05). Activities of daily living did not change significantly (p=0.332). Hospitalization PEmb-QoL scores significantly predicted three-month scores (p<0.001), independent of PESI, sPESI, and age. Conclusion Quality of life improved within three months after acute PE across most PEmb-QoL domains. Scores obtained during hospitalization predicted three-month outcomes. Early PEmb-QoL assessment may help identify patients at risk of persistent quality-of-life impairment and guide follow-up and rehabilitation.

Background: One-third of people with epilepsy have drug-resistant epilepsy, making surgical treatment necessary. Comprehensive pre-surgical evaluations, including long-term video-electroencephalographic (VEEG) monitoring, magnetic resonance imaging (MRI), and neuropsychological testing, are essential components of epilepsy presurgical evaluation. The Epilepsy Center at the Mongolian-Japanese Hospital of MNUMS was established in September 2022 and introduced long-term video-EEG monitoring in May 2023. This marked the first time in Mongolia that comprehensive evaluation for epilepsy surgery became available. Aim: To evaluate the role and outcomes of long-term video-EEG monitoring in the pre-surgical assessment of epilepsy patients Materials and Methods: A prospective cohort study was conducted at the Epilepsy Center of the Mongolian-Japanese Hospital from May 2023 to March 2025. Patients who underwent VEEG and comprehensive pre-surgical evaluation were included. Data included demographic information, seizure history, imaging findings, and neurophysiological assessments (routine, sleep-deprived, and long-term video EEG). Patients were divided into two groups based on whether they met criteria for epilepsy surgery, and surgical outcomes were compared between these groups. Results: A total of 297 patients (104 children and 193 adults) participated in the study. Of these, 96 (32%) were diagnosed with temporal lobe epilepsy and underwent pre-surgical evaluation. The mean age of this group was 33±9.2 years; male-to-female ratio was 1:1. Age of seizure onset was 20±10.9 years, and the mean duration of epilepsy was 14.8±10.3 years. Etiologies included meningitis (21.7%), febrile seizures (15.2%), birth complications (12.5%), and traumatic brain injury (12.5%). The average duration of VEEG monitoring was 1.45±0.68 days, during which 161 seizures were recorded (average 2.64 per patient). No seizures were captured in 35 patients. Among the 96 patients, 29 met the criteria for surgical intervention, and 11 underwent temporal lobe epilepsy surgery. Surgical outcomes were significantly better compared to the non-surgical group (p<0.05). Conclusion Long-term video-EEG monitoring plays a critical role in precisely localizing the epileptogenic zone, identifying seizure types, establishing differential diagnoses, and optimizing surgical candidacy. It is confirmed as an essential diagnostic tool in the pre-surgical evaluation for epilepsy surgery.

Background: Mining is a major source of income, economic benefits, and job creation; however, it remains one of the most hazardous occupations in terms of health. Physically demanding, labor-intensive, hot, humid, noisy, and dusty work environments have a negative impact on the physical and psychological health of mine workers. Several factors, including age, gender, years of service, workload, stress, and fatigue, can affect sleep quality. Lack of sleep can lead to poor concentration, reduced alertness, impaired decision-making, and an increased risk of workplace injuries. While many studies have explored sleep quality and its risk factors in the general population, few have focused specifically on miners. This gap is the primary motivation for conducting the present study. Aim: To examine the risk factors affecting the sleep quality of dayshift workers at Baganuur Joint Stock Company. Materials and Methods: This cross-sectional study included 129 day-shift workers from Baganuur Joint Stock Company and was conducted between October and November 2023. Sleep quality was assessed using the 19-item Pittsburgh Sleep Quality Index (PSQI) questionnaire. Data were analyzed using SPSS version 26.0, with statistical significance set at p < 0.05. Results: Among the study participants, 86% (n = 111) were male. A total of 58.9% had been employed for less than 10 years, and 86% were always on call during non-working hours. Overall, 51.2% of the participants had poor sleep quality. Female gender (55.0%, p = 0.032) and being always on call during non-working hours (93.9%, p = 0.008) were significantly associated with poor sleep quality. Logistic regression analysis revealed that being female increased the risk of poor sleep quality (OR = 0.315, 95% CI = 0.105–0.944, p = 0.039). Conclusions 1. The majority of participants (51.2%) reported poor sleep quality, 2. Gender and being on call during non-working hours were significantly associated with reduced sleep quality among day-shift miners.
