The aim of this study was to examine the neutrophil-to-lymphocyte ratio (NLR) in patients diagnosed with a deep neck infection (DNI) to identify helpful indicators for the initial differential diagnosis. This study was conducted as a single-center, retrospective cohort study that utilized data from the electronic medical records of patients who visited the emergency department in a tertiary university hospital between February 2018 and April 2022. The study enrolled patients aged ≥18 years who were diagnosed with tonsillitis with or without DNI during the study period. The NLR of patients without DNI was 6.1 ± 5.03, and the NLR of patients with acute tonsillitis with DNI was 8.0 ± 5.67, showing significant differences. The rate of admission in the general wards (GWs) and ICUs was significantly higher in patients with DNI, and the length of hospital stay was also significantly longer in patients with DNI. Older age, male, lower body temperature, C-reactive protein, and NLR were significant independent risk factors for DNI in patients with tonsillitis. The cutoff value for predicting DNI in patients with body temperature <37.5 was 3.09. The NLR of patients with tonsillitis, especially those with normal body temperature, can be used to predict their prognosis.

Objective: The aim of this study is to evaluate the efficacy of endovascular treatment for nondissected diseases of the ascending aorta. Data Sources. PubMed, Embase, and SciELO. Review Methods. In this study, we conducted a search on the PubMed, Embase, and SciELO databases for all cases of ascending aortic endovascular repair included in the literature published between January 2007 and July 2023, excluding type A aortic dissection. We reviewed 56 case reports and 7 observational studies included in this study, assessing the techniques, equipment, procedural steps, and results. We summarized the age, complications, follow-up time, and access route.

Results: This study includes 63 articles reporting 105 patients (mean age: 64.96 ± 17.08 years) who received endovascular repair for nondissected ascending aortic disease. The types of disease include aneurysm (N = 16), pseudoaneurysm (N = 71), penetrating aortic ulcer (N = 10), intramural hematoma (N = 2), thrombosis (N = 2), iatrogenic coarctation (N = 1), and rupture of the aorta (N = 3). The success rate of surgery is 99.05% (104/105). Complications include endoleak (10.48%, 11/105), stroke (5.71%, 6/105), postoperative infection (1.91%, 2/105), acute renal failure (0.95%, 1/105), aortic rupture (0.95%, 1/105), thrombosis (0.95%, 1/105), and splenic infarction (0.95%, 1/105). Five patients required conversion to open surgery, two patients underwent endovascular reintervention, and four of these five patients underwent surgery due to endoleak. Early mortality was 2.86% (3/105).

Conclusion: While the viability and results of endovascular repair for the treatment of ascending aortic disease are acknowledged in some circumstances, further research is needed to determine the safety and effectiveness of endovascular treatment for ascending aortic disease.

Objective: The chest computed tomography (CT) examination is an important clinical examination in the diagnosis and monitoring of paraquat- (PQ-) induced lung injury. The aim of this study was to explore the prognostic value of the average lung CT number acquired by quantitative CT techniques in patients with acute paraquat poisoning in the early stages of the disease.

Methods: 46 patients who suffered from acute PQ poisoning in the emergency department of the Nanjing Drum Tower Hospital from January 2015 to June 2020 were enrolled in the present study. The patients were divided into survival group (n = 21) and nonsurvival group (n = 25). Clinical data were collected from subjects who met the inclusion criteria, including general information, personal disease history, and laboratory test indicators. The average lung CT numbers of each patient were obtained by quantitative CT techniques. Receiver operating characteristic (ROC) analysis was conducted to assess the prognostic value of average lung CT number in patients with acute paraquat poisoning.

Results: The average CT numbers of the middle-lung, lower-lung, and whole lung fields in the nonsurvival group were significantly higher than those of the survival group (p < 0.0001). However, the upper-lung field was not significantly different between the two groups (p = 0.7765). The AUCs of different levels ranged from 0.554 to 0.977, among which the lower-lung field presented the largest AUC of 0.977 (95% CI: 0.943∼1; cut-off value: -702Hu; sensitivity 96%; specificity, 90.5%; YI: 0.865), followed by the whole lung field 0.914 (95% CI: 0.830∼0.999; cut-off value: -727Hu; sensitivity 76%; specificity, 95.2%; YI: 0.712) and the middle-lung field 0.87 (95% CI: 0.768∼0.971; cut-off value: -779Hu; sensitivity 80%; specificity, 85.7%; YI: 0.657).

Conclusion: The present study indicated that the average lung CT number could be used to evaluate the relationship between the severity of PQ-induced lung injury and prognosis, especially in the lower-lung field. However, further research is needed to draw a clear conclusion.

Introduction: Urinary tract infections (UTIs) and sexually transmitted infections (STIs) can have overlapping signs, symptoms, and findings on urinalysis. Our objective was to determine if patient or provider demographics are associated with differences in the diagnosis and management of UTIs and STIs in the emergency department (ED).

Methods: We analyzed 38,062 ED patient encounters from a single healthcare system between April 18, 2014, and March 7, 2017. All encounters were women ≥18 years of age and not admitted to the hospital. We performed logistic regression using patient and provider demographics, laboratory testing results, ED triage data, and ED diagnoses.

Results: The patient's age, race, and marital status were not associated with having an ED UTI diagnosis with a urine culture ≥10,000 colony forming units (CFUs)/mL (vs. <10,000 CFUs/mL). Patient race and the sex of the ED provider were not associated with differences in empiric antibiotic treatment for gonorrhea and chlamydia during the ED encounter. Patient's race and the sex of the ED provider were also not associated with discordance between empiric antibiotic therapy given in the ED and the results of gonorrhea and chlamydia tests that resulted following the ED encounter.

Conclusion: In our multivariate analyses, we did not observe that the patient's race resulted in significant differences in the diagnosis of UTIs with bacteriuria ≥10,000 CFU/mL or differences in the empiric treatment of gonorrhea and chlamydia infections among those tested for the infection in the ED. The patient's age and marital status, but not the provider's sex, were significantly associated with differences in the management of gonorrhea and chlamydia.

Background: The extensive burns devastate trauma. The research was designed to analyse the predictive value of early platelet (PLT) indices on the development of acute kidney injury (AKI) after severe burns.

Methods and results: 186 patients with extensive burns (burn area ≥30%) were eventually involved. Multivariate analyses pointed out that platelet distribution width (PDW) in the first 24 h after admission was an independent risk factor for AKI, severe AKI, and RRT requirement in patients with severe burns, and AKI risk showed an increase of 30.9% per increase of 1% in PDW (OR = 1.309, CI, 1.075-1.594, and P = 0.007). It was found that the area under the ROC curve (AUC) of PDW predicting AKI was 0.735 and that the AUC value was 0.81 for AKI after combining PDW and blood urea nitrogen (BUN). Based on the cut-off value PDW = 17.7%, patients were divided into high- (PDW ≥17.7%) and low-risk (PDW <17.7%) groups. In the KM analysis, there was a higher cumulative incidence of AKI if patients were in a high-risk group (in 30 days); and the stages of AKI showed a linear upward trend (chi-square test for linear trend P  <  0.001) as there was an increase in the risk level.

Conclusion: The PDW level in the early stage serves as an important risk factor for AKI, severe AKI, and RRT requirement in extensive burns. When PDW >17.7%, burn patients are not only at a higher risk for AKI but may also have higher AKI severity. Due to low cost and wide availability, PDW has the potential to be the tool that can predict AKI in extensive burn patients.

Objective: To summarize the best evidence of emergency target blood pressure management for acute aortic dissection and provide guidance for evidence-based practice of emergency target blood pressure management.

Methods: According to the "6S" evidence pyramid model, the evidence of emergency target blood pressure management of acute aortic dissection in various foreign databases and websites of professional associations from January 1, 2010, to August 1, 2022, was retrieved, including clinical decision-making, guidelines, expert consensus, systematic reviews, randomized controlled trials, cohort studies, and case series. Two researchers used the corresponding document quality evaluation tools to evaluate the documents and extracted and summarized the evidence of documents above grade B.

Results: A total of 17 articles were included, including 6 clinical decision-making articles, 5 guidelines, 2 expert consensus articles, 1 systematic review article, 1 randomized controlled trial article, 1 cohort study article, and 1 case series article, forming 36 best evidences, including 9 topics, which are target value setting, management strategy, disease observation, medical history collection, monitoring methods, vasoactive drugs, nonvasoactive drugs, related examinations, and patient education.

Conclusion: The best evidence summarized provides a reference for doctors and nurses in the emergency department to manage the emergency target blood pressure of patients with acute aortic dissection. It is recommended that doctors and nurses in the emergency department follow the best evidence summarized to develop individualized target blood pressure management plan for patients.

Objectives: To analyze the effects of deep hyperthermia combined with intraperitoneal chemotherapy on liver-kidney function, immune function, and long-term survival in patients with abdominal metastases.

Methods: A total of 88 patients with abdominal metastases confirmed in the hospital were enrolled as the research objects between August 2018 and August 2021. They were randomly divided into control group (n = 44) and observation group (n = 44). The control group was treated with intraperitoneal chemotherapy, while observation group was additionally treated with deep hyperthermia. The general clinical data of patients were recorded. The short-term and long-term curative effects were evaluated. The occurrence of side effects in both groups was recorded. Before and after treatment, levels of alanine transaminase (ALT) and aspartate transaminase (AST) were detected by full-automatic biochemical analyzer. The level of blood urea nitrogen (BUN) was detected by the urease electrode method. The level of serum creatinine (Scr) was detected by the picric acid method. The levels of CD₃ ⁺, CD₄ ⁺, CD₈ ⁺, and NK cells were detected by BD FACSCalibur flow cytometer.

Results: There was no significant difference in clinical data between the two groups (P > 0.05). In the observation group, ORR was significantly higher than that in the control group (54.55% vs 29.55%) (P < 0.05), OS was significantly longer than that in the control group (P < 0.05), and median survival time and mPFS were longer than those in the control group. After treatment, the levels of ALT, AST, BUN, and Scr were significantly increased in the control group (P < 0.05), but there was no significant difference in peripheral blood CD₃ ⁺, CD₄ ⁺, and CD₄ ⁺/CD₈ ⁺ ratio or count of NK cells before and after treatment (P > 0.05). Before and after treatment, there was no significant difference in the levels of ALT, AST, BUN, and Scr in the observation group (P > 0.05). After treatment, peripheral blood CD₃ ⁺, CD₄ ⁺, and CD₄ ⁺/CD₈ ⁺ ratio and count of NK cells were all increased in the observation group, significantly higher than those in the control group (P < 0.05). The incidence of chemotherapy side effects in the observation group was significantly lower than that in the control group (P < 0.05).

Conclusion: The short-term and long-term curative effects of deep hyperthermia combined with intraperitoneal chemotherapy are good on patients with intraperitoneal metastases, with less damage to liver-kidney function. It is beneficial to enhance immune function of patients, with mild side effects.

Nasal bone is a long, paired series of small bones, which is narrow at the top and broad at the bottom, that forms the base of the nasal dorsum. Together with the nasal part of the frontal bone, the frontal process of the maxilla and the middle plate of the ethmoid bone constitute the bone scaffold of the external nose. In this paper, the DICOM image data file was imported into the Mimics software for 3D reconstruction. At the same time, the Geomagic software was used for relevant image processing, and the finite element software ANSYS was used to establish a finite element model to analyze the stress characteristics of the nasomaxillary complex. Results. The maximum principal stress and maximum strain force at the lower segment of nasal bone and the junction of nasal bone and maxilla were relatively large. When the same external force acts on the lower segment of the nasal bone and the angle is 0° (sagittal force), the maximum principal stress and maximum strain force are the smallest. When the angle continues to increase, the maximum principal stress and maximum strain force continue to increase.

Objective: To explore the clinical effect and aesthetic evaluation of minimally invasive implant in the treatment of dentition defect.

Methods: From April 2020 to May 2021, 60 patients who received implant restoration were collected as the research objects. Randomly divided into minimally invasive surgery group (30 patients) and routine surgery group (30 patients). The postoperative antibiotic use time, pain disappearance time, swelling degree, and pain degree of the two groups were compared. Follow-up for one year, record and compare the success rate of implants and aesthetic evaluation of restoration between the two groups. The evaluation of patients' satisfaction with restoration was collected and compared.

Results: The operation time and antibiotic use time of patients in minimally invasive surgery group were significantly shorter than those in conventional surgery group, and the swelling degree rating was significantly better than that in conventional surgery group, with statistical significance (P < 0.05). The number of patients with no pain (0 degree) and mild pain (degree) in minimally invasive surgery group was significantly higher than that in routine surgery group, and the difference was statistically significant (P < 0.05). One year after the repair, the success rate of implants in minimally invasive surgery group was 100.00% compared with that in routine surgery group (93.33%), and the difference was not statistically significant (P > 0.05). The aesthetic effect scores of patients in minimally invasive surgery group were higher than those in routine surgery group in seven items: proximal gingival papilla, distal gingival papilla, labial gingival margin curvature, labial gingival margin height, root convexity, soft tissue color, and soft tissue texture, with statistical significance (P < 0.05). The satisfaction scores of the patients in minimally invasive surgery group in chewing function, comfort, aesthetics, retention function, and language function were higher than those in conventional surgery group, and the differences were statistically significant (P < 0.05).

Conclusion: Minimally invasive implant can achieve the same effect as conventional implant, and it has the advantages of lower postoperative swelling, shorter pain time, better aesthetic effect, and higher satisfaction after restoration.
