Objective:To investigate the relationship between symptoms of vertigo and vestibular functions and short-term hearing outcomes in patients with flat descending sudden sensorineural hearing loss （SSNHL）. Methods:A retrospective review was conducted of the vestibular symptoms observed in 48 patients with unilateral flat-down sudden sensorineural hearing loss treated at the Department of Otolaryngology Head and Neck Surgery, Xinhua Hospital, Shanghai Jiao Tong University School of Medicine. Symptoms of vertigo and the results of cervical vestibular-evoked myogenic potentials （cVEMP）, ocular VEMP （oVEMP）, caloric test and video head-impulse test （vHIT） were collected to determine whether these factors could predict therapeutic efficacy. Results:The symptoms of vertigo was not correlated with prognosis （P>0.05） or with abnormal vestibular functions （P>0.05）. Patients with abnormal cVEMP, oVEMP, caloric test or vHIT showed significantly lower effective rates （32.0%, 44.0%, 32.0%, and 24.0%, respectively）; the greater the number of abnormal tests, the poorer the outcome. Patients with all four tests abnormal gained only （3.13±15.97） dB HL in hearing recovery, whereas those with normal cVEMP, oVEMP, caloric test or vHIT showed better chances of hearing improvements by （29.22±20.31）, （31.18±21.59）, （26.17±21.31）, and （26.38±24.05） dB HL, respectively. Conclusion:Vestibular function effectively predicts prognosis in flat descending SSNHL. Patients with abnormal vestibular tests, regardless of symptoms of vertigo, responded poorly to treatment, whereas those with normal cVEMP, oVEMP, caloric test and vHIT results achieved better hearing recovery. Abnormal vestibular function implies more extensive and severe inner-ear lesions in patients with SSNHL.

OBJECTIVE: To study the relevant factors affecting the occurrence of adjacent vertebral fractures in women with osteoporotic vertebral compression fractures after conservative treatments. METHODS: A total of 98 elderly female patients diagnosed with osteoporotic vertebral compression fractures and treated from January 2020 to January 2022 were retrospectively analyzed. The average age was (73.05±7.38) years old. Based on the follow-up results after two years of injury, the patients were divided into the adjacent vertebral fracture group (24 cases) and the non-adjacent vertebral fracture group (74 cases). The following factors were recorded for each patient:age, initial bone density, follow-up bone density, bone density changes, initial VAS score, degree of fracture compression, presence of old fractures, use of zoledronic acid, use of parathyroid hormone analogs, occurrence of complications, and further compression of the affected vertebrae. Univariate and multivariate Logistic regression analyses were performed to analyze the associated risk factors. RESULTS: Univariate analysis revealed that in elderly women undergoing conservative treatment for osteoporotic vertebral compression fractures, the degree of fracture compression, follow-up bone density, changes in bone density, use of zoledronic acid, and use of parathyroid hormone analogs were statistically significant(P<0.05). Multivariate Logistic regression analysis demonstrated that the degree of fracture compression 95%CI(0.040, 0.571), P=0.005, OR=0.151, changes in bone density 95%CI(1.264, 1 360.732), P=0.036, OR=41.477, and use of parathyroid hormone analogs 95%CI(1.638, 31.625), P=0.009, OR=7.196 were risk factors affecting the occurrence of adjacent vertebral fractures following vertebral compression fractures in elderly women with osteoporosis. CONCLUSION The degree of fracture compression, changes in bone density, and the use of parathyroid hormone analogs are factors influencing the occurrence of adjacent vertebral fractures following vertebral compression fractures in elderly women with osteoporosis. For patients with mild compression fractures (gradeⅠ), conservative treatment can be achieved by intensifying anti-osteoporosis therapy and using parathyroid hormone analogs.

PURPOSE: The rate of complications among patients undergoing surgery has increased due to infection with SARS-CoV-2 and other variants of concern. However, Omicron has shown decreased pathogenicity, raising questions about the risk of postoperative complications among patients who are infected with this variant. This study aimed to investigate complications and related factors among patients with recent Omicron infection prior to undergoing orthopedic surgery. METHODS: A historical control study was conducted. Data were collected from all patients who underwent surgery during 2 distinct periods: (1) between Dec 12, 2022 and Jan 31, 2023 (COVID-19 positive group), (2) between Dec 12, 2021 and Jan 31, 2022 (COVID-19 negative control group). The patients were at least 18 years old. Patients who received conservative treatment after admission or had high-risk diseases or special circumstances (use of anticoagulants before surgery) were excluded from the study. The study outcomes were the total complication rate and related factors. Binary logistic regression analysis was used to identify related factors, and odds ratio (OR) and 95% confidence interval (CI) were calculated to assess the impact of COVID-19 infection on complications. RESULTS: In the analysis, a total of 847 patients who underwent surgery were included, with 275 of these patients testing positive for COVID-19 and 572 testing negative. The COVID-19-positive group had a significantly higher rate of total complications (11.27%) than the control group (4.90%, p < 0.001). After adjusting for relevant factors, the OR was 3.08 (95% CI: 1.45-6.53). Patients who were diagnosed with COVID-19 at 3-4 weeks (OR = 0.20 (95% CI: 0.06-0.59), p = 0.005), 5-6 weeks (OR = 0.16 (95% CI: 0.04-0.59), p = 0.010), or ≥7 weeks (OR = 0.26 (95% CI: 0.06-1.02), p = 0.069) prior to surgery had a lower risk of complications than those who were diagnosed at 0-2 weeks prior to surgery. Seven factors (age, indications for surgery, time of operation, time of COVID-19 diagnosis prior to surgery, C-reactive protein levels, alanine transaminase levels, and aspartate aminotransferase levels) were found to be associated with complications; thus, these factors were used to create a nomogram. CONCLUSION Omicron continues to be a significant factor in the incidence of postoperative complications among patients undergoing orthopedic surgery. By identifying the factors associated with these complications, we can determine the optimal surgical timing, provide more accurate prognostic information, and offer appropriate consultation for orthopedic surgery patients who have been infected with Omicron.

OBJECTIVE: To analyze the distribution characteristics of glucose-6-phosphate-dehydrogenase (G6PD) mutations and their enzyme activity in newborns patients with G6PD deficiency in Guilin region. METHODS: From July 2022 to July 2024, umbilical cord blood samples from 4 554 newborns in Guilin were analyzed for G6PD mutations using fluorescence PCR melting curve analysis. Enzyme activity was detected in 4 467 cases using the rate assay. RESULTS: Among 4 467 newborns who underwent G6PD activity testing, 162 newborns (3.63%) were identified as G6PD-deficient, including 142 males (6.04%) and 20 females (0.94%), the prevalence of G6PD deficiency was significantly higher in males than in females (P < 0.001). Genetic analysis of 4 554 newborns detected G6PD mutations in 410 cases (9%), including 171 males (7.13%) and 239 females (11.09%), with a significantly higher mutation detection rate in females than in males (P < 0.001). A total of nine single mutations and four compound heterozygous mutations were identified. The most common mutations were c.1388G>A (33.66%), c.1376G>T (23.66%) and c.95A>G (16.34%). Among newborns who underwent both enzyme activity and genetic mutation testing, males with G6PD mutations had significantly lower enzyme activity than that of females with G6PD mutations(P < 0.001). Specifically, among newborns carrying the mutations c.1388G>A, c.1376G>T, c.95A>G, c.1024C>T or c.871G>A, males consistently exhibited lower enzymatic activity than females with the same mutations (P < 0.001). Furthermore, in male G6PD-deficient newborns, the enzyme activity levels in those carrying c.1388G>A, c.1376G>T, c.95A>G, c.1024C>T, or c.871G>A were lower than those in both the control group and the c.519C>T group (P < 0.05). CONCLUSION This study provides a comprehensive profile of G6PD deficiency incidence and mutation spectrum in the Guilin region. By analyzing enzyme activity and genetic mutation results, this study provides insights into potential intervention strategies and personalized management approaches for the prevention and treatment of neonatal G6PD deficiency in the region.
