Background: Total knee replacement arthroplasty (TKA) is an essential surgical treatment method performed when the cartilage surfaces of the knee joint undergo irreversible changes due to aging, trauma, genetics, or lifestyle factors. In our country, approximately 2.500 knee replacement surgeries are performed annually. Aim: To investigate the Lysholm scores of patients who underwent total knee replacement arthroplasty and the factors influencing these scores. Materials and Methods: This study was conducted using a retrospective cohort study design. The research was carried out at the First Central Hospital of the country, involving 186 patients who visited the Department of Joint Center from January 2007 to May 2023. Participants provided demographic data, information on comorbidities, alcohol and tobacco use, physical activity, and lifestyle factors through a 56-question survey, divided into two groups. The stability and function of the knee joint were assessed using the Lysholm assessment. A score of 95-100 indicated excellent, 84-94 good, 65-83 moderate, and less than 65 poor. Statistical analysis of the results was performed using SPSS version 26.0. Results: Out of 185 participants, the mean age was 71.83±7.83 years, with 18.9% (n=35) males and 81.1% (n=150) females. The demographic factors such as gender, age group, BMI, and years after surgery were significantly associated with the Lysholm score (p=0.001). Logistic regression analysis identified that age (OR, 2.014; 95% CI, 1.620-1.659; p=0.001), excess weight (OR, 1.328; p=0.001; 95% CI, 0.469-3.765), and years after surgery (OR, 1.194; 95% CI, 0.533- 2.676; p=0.037) were factors influencing the scores Conclusion 037) were factors influencing the scores. Conclusion: The number of years after total knee replacement arthroplasty and patient age significantly affected Lysholm evaluation scores

Introduction: The theory that usingmobile bearing (MB) design for total kneereplacementsurgeries can reduce the riskof tibial component loosening compared tofixed-bearing (FB) designs is still unclear.Arthroplastic surgeries developed rapidlywithin recent 10 years, but there is no similarstudy performed yet. This randomized studyinvestigated the impact of prosthesis design toloosening of components at 2 years for totalknee replacement surgeries.Materials and Methods: 479 patientswho underwent total knee arthroplastyin FirstCentral Hospital of Mongolia were allocated toeither FB or MB tibialarticulation.We comparedour results to similar studies which performedabroad due to there is no such a studyperformed before in Mongolia.Results: There is no significant differenceby age, sex, weight, height, body mass index,operation side (right or left) in both groups.Pre- and postoperative range of motionwasalmostsame for MB and FB groups.Butloosening complication was higher for the FBgroup (1.16%) than MB group (0%).Conclusion: Using MB design for total kneearthroplasty has less loosening complicationthan using FB design in Mongolians. Bonemineral density (dual energy absorptiometry)and radiostereometric analysis are necessaryfor widening studies in field of total kneereplacement surgeries in the future.

Children under 5 years of age in developing countries are particularly vulnerable to malnutrition. Malnutrition affects 50% of hospitalized children and 25–70% of the critically ill children. Malnutrition interferes with the appropriate response of the body to disease and predisposes to infection and to the onset of multiorgan failure, increasing morbidity and mortality, the mean length of hospital stay, and health costs. Aim: A prospective cohort study of children admitted to the tertiary pediatric ICU between January 2009 and January 2014 was carried out. To assess the malnutrition type, and impact of nutritional status on outcomes like mortality rate, disease, complication in critically ill children.To the study were enrolled 138 children admitted to the pediatric intensive care units of the NationalCenter for Maternal and Childrens Hospital. The study protocol was approved by the Ethics Committee of the MNUMS, and written informed consent was obtained from all study participants. Nutritional status was determined using Waterlow criteria.Total participants were 49.3% (n=68) of male, 50.7% (n=70) female. 138 children with a mean age 4.4 months ±3.6/ Std.Er/, min = 1 month, max = 12 months, mode = 1 month. n=70(50.7%) acute malnutrition, n=58(42%) chronic malnutrition by Waterlow criteria. In malnutrition group was assessed patient with ricket n=36 (26.1%), patient with anemia n=56(58.9%)While malnutrition is a major problem in pediatric intensive care units. Acute malnutrition moreoccurred in the pediatric intensive care.Malnutrition more occurring of intrauterine infection, genetic disorder, hematology disease’s patients.

Acute lung injury and acute respiratory distress syndrome among children are clinical entities of multifactorial origin requiring intensive care. Pediatric acute respiratory distress syndrome is a devastating lung condition with high mortality being the end result of a wide variety of inciting events. The purpose of this article is to review recent evidence for the epidemiology, clinical signs, diagnosis and treatment of the acute respiratory distress syndrome in chidlren.
