Objective To analyze the changing trends of the burden of non-alcoholic fatty liver disease(NAFLD)in China from 1990 to 2021 and provide a basis for formulating prevention and treatment strategies.Methods The standardized incidence rate,prevalence,mortality,and disability-adjusted life year(DALY)rate of NAFLD in China from 1990 to 2021 were extracted from the Global Burden of Disease Study 2021.The average annual percentage change of rate data was calculated by Joinpoint 4.2 and the age,period,and birth cohort effects of the prevalence and DALY rate were analyzed by the age-period-cohort model.Results Compared to 1990,the incidence rate and prevalence of NAFLD have been on the rise,while the mortality and DALY rate have been declining.The age effect curves of prevalence and DALY rate showed an upward trend followed by a downward trend for both males and females.With the period from 1992 to 1996 as the reference group,the period effect curve of prevalence showed a downward trend followed by an upward trend,being the lowest in the period from 2002 to 2006(RR=0.93).The period effect curve of DALY rate showed a downward trend from 1992 to 2011 and then tended to flatten out.With the period from 1972 to 1981 as the reference group,the birth cohort effect curve of prevalence showed a steady upward trend in the general population and both male and female populations.The birth cohort effect curve of DALY rate showed an overall upward trend followed by a downward trend,with the peak occurring in the birth cohort group between 1922 and 1931.The DALY rate of NAFLD caused by smoking and high fasting blood glucose has shown a downward trend since 2014,and fasting blood glucose gradually became the dominant factor as age increased.Conclusions From 1990 to 2021,NAFLD in China has shown a rising prevalence but a significantly declining DALY rate.This suggests that current prevention and control strategies are effective,and further efforts should be made to raise residents' health awareness in controlling the occurrence and development of NAFLD.

PURPOSE: We carried out the study aiming to explore and analyze the risk factors, the distribution of pathogenic bacteria, and their antibiotic-resistance characteristics influencing the occurrence of surgical site infection (SSI), to provide valuable assistance for reducing the incidence of SSI after traumatic fracture surgery. METHODS: A retrospective case-control study enrolling 3978 participants from January 2015 to December 2019 receiving surgical treatment for traumatic fractures was conducted at Tangdu Hospital of Air Force Medical University. Baseline data, demographic characteristics, lifestyles, variables related to surgical treatment, and pathogen culture were harvested and analyzed. Univariate analyses and multivariate logistic regression analyses were used to reveal the independent risk factors of SSI. A bacterial distribution histogram and drug-sensitive heat map were drawn to describe the pathogenic characteristics. RESULTS: Included 3978 patients 138 of them developed SSI with an incidence rate of 3.47% postoperatively. By logistic regression analysis, we found that variables such as gender (males) (odds ratio (OR) = 2.012, 95% confidence interval (CI): 1.235 - 3.278, p = 0.005), diabetes mellitus (OR = 5.848, 95% CI: 3.513 - 9.736, p < 0.001), hypoproteinemia (OR = 3.400, 95% CI: 1.280 - 9.031, p = 0.014), underlying disease (OR = 5.398, 95% CI: 2.343 - 12.438, p < 0.001), hormonotherapy (OR = 11.718, 95% CI: 6.269 - 21.903, p < 0.001), open fracture (OR = 29.377, 95% CI: 9.944 - 86.784, p < 0.001), and intraoperative transfusion (OR = 2.664, 95% CI: 1.572 - 4.515, p < 0.001) were independent risk factors for SSI, while, aged over 59 years (OR = 0.132, 95% CI: 0.059 - 0.296, p < 0.001), prophylactic antibiotics use (OR = 0.082, 95% CI: 0.042 - 0.164, p < 0.001) and vacuum sealing drainage use (OR = 0.036, 95% CI: 0.010 - 0.129, p < 0.001) were protective factors. Pathogens results showed that 301 strains of 38 species of bacteria were harvested, among which 178 (59.1%) strains were Gram-positive bacteria, and 123 (40.9%) strains were Gram-negative bacteria. Staphylococcus aureus (108, 60.7%) and Enterobacter cloacae (38, 30.9%) accounted for the largest proportion. The susceptibility of Gram-positive bacteria to Vancomycin and Linezolid was almost 100%. The susceptibility of Gram-negative bacteria to Imipenem, Amikacin, and Meropenem exceeded 73%. CONCLUSION Orthopedic surgeons need to develop appropriate surgical plans based on the risk factors and protective factors associated with postoperative SSI to reduce its occurrence. Meanwhile, it is recommended to strengthen blood glucose control in the early stage of admission and for surgeons to be cautious and scientific when choosing antibiotic therapy in clinical practice.

PURPOSE: The purpose of this study is to surveil the injuries in wrestling according to the different age categories and wrestling styles throughout the competition season. METHODS: The study was designed as a descriptive study. The study was conducted during the wrestling competition season in 2023 (from January 2023 to July 2023), which includes 5 different age categories: U-15, U-17, U-20, U-23, and seniors, along with the Turkey National Wrestling Championships. The data of injuries was recorded immediately after the acute injury was treated by the medical expert during the competitions and evaluated according to the parameters that were obtained. In the statistical analysis, the frequency and percentage values were presented as descriptive statistics and the Chi-square test was used. RESULTS: The study incorporated a total of 6214 wrestlers and a total of 7151 wrestling bouts were performed during these competitions. The analyses indicated that the rate of injury incidence was 42.65‰ in all wrestling styles. When taking account of the injured body parts in all wrestlers' exposures, the occurrence of injuries to the head-face, neck, trunk, upper extremity, and lower extremity, rates of 17.6‰, 1.3‰, 3.6‰, 13.5‰, and 6.6‰, respectively, were observed. According to the pre-diagnosis based on freestyle, Greco-Roman, and female wrestling styles, injuries with bleeding (39.6%, 46.3%, and 14.6%, respectively) and muscle strain (37.9%, 28.7 %, and 52.6%, respectively) most often occurred. CONCLUSION The study findings indicate that most cases of injury appeared to occur in bleeding and muscle strain in all wrestling styles. We suggest that medical experts should set up their health equipment with consideration to the injuries that occur most frequently.

PURPOSE: Orotracheal intubation is one of the most frequently used techniques in emergency procedures and especially in anesthesia and resuscitation. Teeth may be "victims" of the orotracheal intubation. Several factors may predispose to these accidents. The aim of this study is to determine the incidence of oral trauma that occurs during scheduled and urgent oral tracheal intubation, and identify the risk factors, the types and locations of these dental injuries. METHODS: It is a cross-sectional study that lasted 6 months from June to November 2022. This study was carried out in several departments. An examination of the dental and periodontal status of patients who will undergo surgery under general anesthesia was performed before the operation according to the surgical program. Yet, in emergency settings, this examination was not possible. Patients with anterior edentation and patients refusing participation in the study were excluded. After the surgery, included patients were examined to detect eventual dental trauma such as fracture, luxation, and contusion. Collected data were entered and analyzed using SPSS version 18 software. The Wilcoxon Mann-Whitney U test was used to compare quantitative variables. The Chi-square test was used to compare qualitative variables with a statistical significance level of 5% (p < 0.05). RESULTS: There were 43 patients included in the study, and dental trauma was noted in 11 patients (25.6%). Their mean age was (59.8 ± 15.4) years. The statistical analysis shows that there is a significant relationship between age (over 40 years old) and trauma (p = 0.004). Among the traumatized group, orotracheal intubation was undergone for 8 cases according to the surgical program whereas it was performed, for 3 cases, in emergency settings. The difference between the 2 types of intervention is statistically significant (p = 0.045). The odds ratio was 0.086 (95% CI: 0.008 - 0.942). A Mallampati score of 1 was rated for 6 injured (54.5%). The difference between the difficulty of the intubation evaluated by the Mallampati score and the occurrence of trauma was statistically insignificant (p = 0.278). The dental partial dislocation was the most frequent trauma (6 cases, 54.5%). The maxillary teeth were the most affected (n = 13, 72.2%). CONCLUSION According to the present study, the incidence of orotracheal intubation dental traumas is relatively high. The age of the patient is one of the factors predisposing to these traumas. In scheduled surgery, orotracheal intubation is quietly performed during general anesthesia, and the risk of incidence of dental trauma is reduced than in emergency settings.

PURPOSE: Femur fractures are among the most common fractures treated surgically, representing a significant challenge for the orthopedic surgeon. Peri-implant femoral fractures (PIFFs) represent a rare complication of the surgical treatment. It is necessary to pay attention during osteosynthesis, evaluating not only the fracture site but the entire femoral skeletal structure, the characteristics of the fracture, the health comorbidities, and the risk of malunion and pseudarthrosis. There are few studies on the incidence, treatment, and outcomes of PIFFs near osteosynthesis. This study aimed to investigate PIFF after osteosynthesis of femoral fractures and evaluate the mortality after surgery and the morbidity associated with these types of fractures. METHODS: A retrospective cohort study was carried out at the IRCCS Galeazzi Orthopedic Institute, Milan, Italy, between January, 2017 and December, 2022. Inclusion criteria were the presence of a femur fracture around an intramedullary nail to treat a previous fracture, follow-up ≥ 12 months, and patients aged ≥ 65 years. Exclusion criterion was intraoperative periprosthetic fractures. The data were expressed as frequency and percentage. Continuous variables were expressed as mean ± standard deviation or median and range. RESULTS: Overall, 25 patients were enrolled (88.0% female) and the mean age was 84.5 years (range of 70 - 92 years). There were 20 patients having type B PIFF and 5 having type C. In 22 patients, multiple comorbidities were found with an average Charlson comorbidity score of 5.5 and the mean time to peri-implant fracture was 38 months. After surgery, 1 patient (4.0%) presented renal failure, 1 (4.0%) needed removal surgery for their loosening, and 2 (8.0%) presented surgical site infection. Nine patients (36.0%) died within 1 year with a mortality rate of 20.0% at 30 days, 8.0% at 3 months, and 8.0% at 12 months. CONCLUSIONS PIFFs in elderly patients are associated with high short-term mortality and morbidity, so careful planning for primary fracture surgery and patient awareness to ensure prolonged compliance and a healthy lifestyle are essential for prevention.

PURPOSE: Intrathoracic and intra-abdominal injuries in patients with rib fractures are often overlooked, leading to delayed and ineffective treatment. However, the relationship between rib fractures and organ damage has been rarely studied. The purpose of this study was to analyze the risk factors associated with intrathoracic and intra-abdominal injuries in patients with rib fractures. METHODS: This retrospective observational study included 1269 patients diagnosed with rib fractures from September 2020 to April 2023. Patient data were collected, including gender, age, body mass index, systolic blood pressure, heart rate, type of rib fracture, number of fractured ribs, location of the rib fracture, and the presence of thoracic and abdominal organ injuries. Patients without imaging examinations, the patient with rib fractures from iatrogenic causes or mental illnesses or rheumatic immune diseases was excluded. The primary outcomes were intra-thoracic and intra-abdominal injuries. Multivariate logistic regression analysis was conducted to identify the risk factors for these injuries in patients with rib fractures. RESULTS: The rib fracture characteristics in the occurrence group included bilateral fractures, higher number of fractures (≥3), and fractures located anteriorly, posteriorly, and laterally, as well as greater fracture displacement, compared to the non-occurrence group. The results of the multivariate logistic regression analysis indicated that age (p=0.016, odds ratio (OR)=0.95, 95% confidence interval (CI: 0.92-0.98), the number of rib fractures (≥3, p=0.001, OR=1.46, 95% CI: 1.13-1.89), rib type (bilateral rib fractures, p=0.043, OR=2.63, 95% CI: 2.16-3.12), and rib fracture location (lateral rib fractures, p=0.041, OR=2.85, 95% CI: 1.31-4.97; posterior rib fractures, p=0.022, OR=3.25, 95% CI: 1.46-6.92) were independent risk factors for thoracic and abdominal organ injuries in patients with traumatic rib fractures. CONCLUSIONS Patients with rib fractures resulting from blunt trauma, particularly those with lateral or posterior rib fractures, fractures involving more than 3 ribs, and bilateral rib fractures, are at an increased risk for significant intrathoracic and intra-abdominal injuries. These findings warrant attention and the implementation of appropriate preventive measures during treatment.

PURPOSE: Polytrauma is still a challenge for health care organizations. Today, the search for factors to reduce lethality continues. This study aims to describe the causes of death associated with polytrauma in 1 year. METHODS: This retrospective study analyzed autopsy data of trauma deaths in Moscow for the whole of 2017. We identified victims with polytrauma, taking into account the Berlin definition as the main inclusion criteria with penetrating and blunt trauma. Each forensic report had information about the pre-hospital and hospital stages of treatment and autopsy data. The exclusion criteria for this study were: isolated injury, forensic reports not related to the examination of entire corpses, and autopsy studies of children (<18 years old). Statistical analysis was performed according to basic principles, including a comparison of groups using the Chi-squared test with Bonferroni comparison test and Fisher's exact test. The critical level of significance (p value) in testing statistical hypotheses in this study was taken as 0.05. RESULTS: We analyzed 2337 forensic medical examinations of victims who died of trauma in Moscow in 2017, of which 41.5% (n = 969) were polytrauma deaths. Most of the victims (65.4%, n = 634) died on the scene, and only 30.0% were admitted to the hospital. The most frequent cause of death was bleeding (72.0%, n = 698), followed by traumatic brain injury (43.8%, n = 424). They accounted for the first peak (78.4%, p = 0.005) of deaths, occurring in the first hours. Then these causes of death in the first peak go down in a few hours, and the second peak of mortality appears in 3 - 7 days (p = 0.001). CONCLUSIONS This is the largest full-year autopsy study of polytrauma victims. Our data show that the main cause of polytrauma death is massive bleeding, with a lethality peak in the first hours after injury. The time distribution of polytrauma deaths has a bimodal pattern - the second period of polytrauma deaths occurs in 3 - 7 days.
