ObjectiveTo investigate the relationship between lumbar facet joint degeneration of each segment and spine-pelvic sagittal balance parameters.
MethodsA retrospective analysis was made the clinical data of 120 patients with lumbar degenerative disease, who accorded with the inclusion criteria between June and November 2014. There were 58 males and 62 females with an average age of 53 years (range, 24-77 years). The disease duration ranged from 3 to 96 months (mean, 6.6 months). Affected segments included L3, 4 in 32 cases, L4, 5 in 47 cases, and L5, S1 in 52 cases. The CT and X-ray films of the lumbar vertebrae were taken. The facet joint degeneration was graded based on the grading system of Pathria. The spine-pelvic sagittal balance parameters were measured, including lumbar lordosis (LL), upper lumbar lordosis (ULL), lower lumbar lordosis (LLL), pelvic incidence (PI), pelvic tilt (PT), and sacral slope (SS). According to normal range of PI, the patients were divided into 3 groups: group A (PI was 1ess than normal range), group B (PI was within normal range), and group C (PI was more than normal range). The facet joint degeneration was compared;according to the facet joint degeneration degree, the patients were divided into group N (mild degeneration group) and group M (serious degeneration group) to observe the relationship of lumbar facet joint degeneration of each segment and spine-pelvic sagittal balance parameters.
ResultsAt L4, 5 and L5, S1, facet joint degeneration showed significant difference among groups A, B, and C (P<0.05), more serious facet joint degeneration was observed in group C;no significant difference was found in facet joint degeneration at L3, 4 (P>0.05). There was no significant difference in the other spine-pelvic sagittal balance parameters between groups N and M at each segment (P>0.05) except for PT (P<0.05).
ConclusionPI of more than normal range may lead to or aggravate lumbar facet joint degeneration at L4, 5 and L5, S1;PT and PI are significantly associated with facet joint degeneration at the lower lumbar spine.
ObjectiveTo analyze the epidemiological characteristics and trends of gallbladder cancer incidence and mortality in Zhejiang cancer registration areas from 2000 to 2021, providing a basis for formulating prevention and control strategies for gallbladder cancer. MethodsData on incidence and mortality were collected from 22 cancer registry areas in Zhejiang Province from 2000 to 2021, calculating the crude incidence (mortality), age-standardized incidence / mortality rate by Chinese standard population(ASR China), age-standardized incidence /mortality rate by World standard population (ASR World) and cumulative rate (0–74 years old). The average annual percentage change (AAPC) was calculated by using Joinpoint software. ResultsIn 2021, the crude incidence of gallbladder cancer in Zhejiang cancer registration areas was 6.79 per 100 000. The ASR China and ASR World were 2.99 and 2.96 per 100 000, respectively, ranking 18th of all new cancer cases. The incidence ASR China in female (3.13 per 100 000) was higher than that in male (2.85 per 100 000). The incidence ASR China in rural areas (3.01 per 100 000) was slightly higher than that in urban areas (2.97 per 100 000). The crude mortality of gallbladder cancer was 5.14 per 100 000, with the mortality ASR China and ASR World of 2.09 and 2.10 per 100 000, respectively, ranking 10th of all new cancer deaths. The mortality ASR China in female (2.19 per 100 000) was higher than that in male (1.98 per 100 000). The mortality ASR China in urban areas (2.11 per 100 000) was slightly higher than that in rural areas (2.07 per 100 000). Both the crude incidence and mortality of gallbladder cancer increased with age. The crude incidence and mortality showed an upward trend over time, with AAPC of 2.59% and 3.75%, respectively (P<0.001). The incidence ASR China did not show significant changes over time (AAPC=0.05%, P=0.856). The incidence ASR China in male and rural areas showed increasing trends over time, with AAPCs of 0.89% (P=0.016) and 1.14% (P=0.001), respectively. The incidence ASR China in female and urban areas showed no significant trends over time, with AAPCs of –0.26% (P=0.503) and –0.02% (P=0.967), respectively. The mortality showed a slower upward trend after adjusting the age structure (AAPC=1.01%, P=0.020). ConclusionsThe elderly population in rural areas, especially elderly women, are the primary targets for the prevention and control of gallbladder cancer. Aging is the main factor contributing to the increase in the incidence and mortality of gallbladder cancer. After adjusting for demographic factors, the overall upward trend of the incidence in the male population and rural areas, as well as mortality, cannot be ignored.
ObjectiveTo analyze the burden and incidence of thyroid cancer in the world and in China based on the 2018, 2020 and 2022 editions of the Global Cancer Statistical Report jointly compiled by the World Health Organization (IARC) and the American Cancer Society. MethodsThe global cancer registry data of GLOBOCAN in 2018, 2020 and 2022 were compiled and analyzed, and the crude and age-standardized rates of thyroid cancer incidence in the world and China were extracted, and the incidence characteristics of thyroid cancer in the world and China were compared. ResultsIn 2022, the number of new thyroid cancers in the world was estimated to be about 821 000, ranking 7th among all cancers, with a crude incidence rate of 10.4 per 100 000. The number of new cases of thyroid cancer in China will be about 466 000, ranking third, with a crude incidence rate of 33.0 per 100 000. There are significant differences in the incidence of thyroid cancer among different genders: in 2022, the number of new cases of thyroid cancer in women is about three times that of men, and the crude incidence rate in women is significantly higher than that in men. From 2018 to 2022, the incidence of thyroid cancer increased year by year in the world and China. ConclusionsThe disease burden of thyroid cancer in China is still heavy and higher than the global level, and the prevention and treatment of thyroid cancer is still facing great challenges.
Objective To explore the effect of multimodal interventions in improving the compliance rate of core infection control measures on reducing the incidence rate of vessel catheter associated infection (VCAI). Methods Inpatients with intravascular catheters in 5 departments with high rates of vascular catheterization and infection of Dongguan People’s Hospital between January 2021 and December 2022 were selected. According to the hospital stay, patients were divided into a pre-intervention group (January to December 2021) and a post-intervention group (January to December 2022). The core infection control measures assessment pass rates of medical staff between the two periods and the differences in the incidence rate of VCAI, average catheterization days, and catheterization rate before and after intervention in both groups were compared. Results A total of 8174 patients were included. Among them, there were 3915 patients in the pre-intervention group and 4259 patients in the post-intervention group. In the pre-intervention group, the total length of hospital stay was 122885 days, the total number of catheterization days was 48028 days, and 28 cases of VCAI occurred. In the post-intervention group, the total length of hospital stay was 126966 days, the total number of catheterization days was 51253 days, and 12 cases of VCAI occurred. After intervention, the compliance rate of VCAI core infection control measures was improved [69.21% (2907/4200) vs. 91.24% (3832/4200); χ2=642.090, P＜0.001], the pass rate of medical staff’s core infection control measures assessment was improved [53.33% (128/240) vs. 91.67% (220/240); χ2=88.443, P＜0.001], the catheterization rate was increased [39.08% (48028/122885) vs. 40.37% (51253/126966); χ2=42.979, P<0.001], and the incidence rate of VCAI was reduced [0.58‰ (28/48028) vs. 0.23‰ (12/51253); incidence-rate ratios =0.40, 95% confidence interval (0.20, 0.79), P=0.008]. Conclusions Improving the compliance rate of VCAI core infection control measures through multimodal interventions can significantly improve the passing rates of core infection control measures of medical staffs. This will help to reduce the incidence of VCAI and ensuring patient safety, provide evidence-based support for the prevention and control of VCAI.
Objective To analyze the incidence and mortality of acute viral hepatitis in China, project its trends from 2022 to 2030, and provide valuable insights for the prevention and control of viral hepatitis. Methods The incidence and mortality rates of acute viral hepatitis in China from 1990 to 2021 were extracted from the Global Burden of Disease 2021 database. The change rates and the estimated annual percentage change (EAPC) for each indicator were calculated. Additionally, an autoregressive integrated moving average (ARIMA) model was used to project the incidence and mortality of acute viral hepatitis in China from 2022 to 2030. Results From 1990 to 2021, the incidence rates of acute hepatitis A (AHA), acute hepatitis B (AHB), acute hepatitis C (AHC), and acute hepatitis E (AHE) in China all showed a declining trend (EAPC=?1.980%, ?2.664%, ?2.078%, ?1.686%; P<0.05), with a particularly marked decrease in mortality (EAPC=?11.662%, ?7.411%, ?12.541%, ?7.504%; P<0.05). According to ARIMA model projections, the incidence rates of AHA and AHB were expected to continue declining from 2022 to 2030, while the incidence rates of AHC and AHE were expected to rise. In 2030, the projected incidence rates of AHA, AHB, AHC, and AHE were 890.425/100000, 824.158/100000, 59.202/100000, and 300.377/100000, respectively. The mortality rates of AHA, AHC, and AHE were projected to remain stable from 2022 to 2030, while the mortality rate of AHB was expected to decline. In 2030, the projected mortality rates of AHA, AHB, AHC, and AHE were 0.002/100000, 0/100000, 0.004/100000, and 0.011/100000, respectively. Conclusions From 1990 to 2021, the overall incidence and mortality of acute viral hepatitis in China showed a downward trend. However, the incidence rates of AHC and AHE may present an upward trend in the future, which suggests that the government and relevant health authorities should adjust their prevention and control strategies in a timely manner.
"Global cancer statistics 2022" based on the latest GLOBCAN data from the International Agency for Research on Cancer (IARC) was recently released, providing a systematic analysis of the incidence and mortality of 36 types of cancer across 185 countries worldwide. The international burden of cancer is expected to continue to increase over the next 30 years, posing a severe public health and social challenge for many countries, including China. This article offers a key point interpretation of the "Global cancer statistics 2022", focusing on the evolution of cancer epidemiology and future development trends. The aim is to broaden the international perspective on cancer prevention and treatment, with the hope of providing reference and guidance for cancer prevention and treatment efforts in our country.
Colorectal cancer is the third most frequently diagnosed cancer and the second leading cause of cancer death worldwide. In recent years, with the development and change of society and economy, the epidemiological characteristics of colorectal cancer related to geographic economy and health resources have caused its incidence to show a trend of regional differentiation. At present, the diagnosis, treatment, prevention and control of colorectal cancer in China are still facing great challenges, therefore, summarizing the risk factors related to the incidence of colorectal cancer in China from the global epidemiological characteristics of colorectal cancer can further guide the prevention, control and clinical diagnosis and treatment of colorectal cancer in China, and is of great significance to improve the heavy burden of colorectal cancer. Therefore, this paper discusses the epidemiological characteristics of colorectal cancer in recent years and the screening policies in different regions based on the report of the International Agency for Research on Cancer and related studies, so as to provide the relevant basis for the prevention and control of colorectal cancer in the new situation in the future.
Objective To comprehensively investigate the incidence of resorption of lumbar disc herniation, and provide reference data for clinical decision-making. Methods Seven electronic databases (PubMed, Embase, the Cochrane Central Register of Controlled Trials, Web of Science, China National Knowledge Infrastructure, Wangfang data and Chongqing VIP database) were searched for relevant studies that might have reported morphologic changes in lumbar disc herniation when reporting the follow-up results of patients with lumbar disc herniation treated non-surgically from inception to March, 2020. Articles were screened according to inclusion and exclusion criteria, and the total number of patients, number of patients with resorption, and other important data were extracted for analysis. Random effect models were used for meta-analysis, and subgroup analysis, sensitivity analysis, meta-regression analysis, and Egger’s test were performed. Results A total of 15712 articles were identified from these databases, and 48 were eligible for analysis. A total of 2880 non-surgically treated patients with lumbar disc herniation were included in the meta-analysis, 1740 of whom presented resorption. Meta-analysis revealed that the incidence of resorption was 0.60 [95% confidence interval (CI) (0.46, 0.72)]. In subgroup analyses, studies that quantitatively measured the resorption of lumbar disc herniation yielded statistically higher pooled incidence [0.73, 95%CI (0.60, 0.85)] than those that used qualitative methods [0.51, 95%CI (0.34, 0.69)] (P=0.0252). The pooled incidence gradually increased in randomized controlled trials (RCTs) [0.50, 95%CI (0.15, 0.85)], non-RCT prospective studies [0.59, 95%CI (0.48, 0.70)] and retrospective studies [0.69, 95%CI (0.36, 0.95)], but the difference was not statistically significant (P=0.7523). The pooled incidence varied from 0.58 [95%CI (0.54, 0.71)] to 0.62 [95%CI (0.49, 0.74)] after the sequential omission of each single study. There was no significant change in the pooled incidence [0.62, 95%CI (0.43, 0.79)] when only low-risk RCTs and high-quality non-RCT studies were included, comparing with original meta-analysis results. Meta-regression showed that measurements partially caused heterogeneity (R2=15.34%, P=0.0858). Egger’s test suggested that there was no publication bias (P=0.4622). Conclusions According to current research, there is an overall incidence of resorption of 60% [95%CI (46%, 72%)] among non-surgically treated patients with lumbar disc herniation. The probability of resorption should be fully considered before making a decision on surgery.
Objective
To review the research progress of the risk factors for slip progression and the pathogenesis of lumbosacral spondylolisthesis, and to discuss the value of Spinal Deformity Study Group (SDSG) classification system for lumbosacral spondylolisthesis.
Methods
Recent articles about the risk factors for slip progression and the pathogenesis of lumbosacral spondylolisthesis were reviewed and comprehensively analyzed with SDSG classification system of lumbosacral
spondylolisthesis.
Results
Pelvic incidence (PI) is the key pathogenic factor of lumbosacral spondylolisthesis. The Meyerding grade of slip, PI, sacro-pelvic balance, and spino-pelvic balance not only are the fundamental risk factors of slip progression, but also are the key factors to determine how to treat and influence the prognosis. Therefore, compared with Wiltse, Marchetti-Bartolozzi, and Mac-Thiong-Labelle classification systems of lumbosacral spondylolisthesis, SDSG classification based on these factors mentioned above, has better homogeneity between the subjects of subgroup, and better reliability, moreover, could better guide operative plan and judge the prognosis.
Conclusion
It is suggested that the SDSG classification system should be the standard classification for lumbosacral spondylolisthesis for the clinical and research work.
ObjectiveTo investigate the value of smart phone Scoliometer software in obtaining optimal lumbar lordosis (LL) during L4-S1 fusion surgery.
MethodsBetween November 2014 and February 2015, 20 patients scheduled for L4-S1 fusion surgery were prospectively enrolled the study. There were 8 males and 12 females, aged 41-65 years (mean, 52.3 years). The disease duration ranged from 6 months to 6 years (mean, 3.4 years). Before operation, the pelvic incidence (PI) and Cobb angle of L4-S1 (CobbL4-S1) were measured on lateral X-ray film of lumbosacral spine by PACS system; and the ideal CobbL4-S1 was then calculated according to previously published methods [(PI+9°)×70%]. Subsequently, intraoperative CobbL4-S1 was monitored by the Scoliometer software and was defined as optimal while it was less than 5° difference compared with ideal CobbL4-S1. Finally, the CobbL4-S1 was measured by the PACS system after operation and the consistency was compared between Scoliometer software and PACS system to evaluate the accuracy of this software. In addition, value of this method in obtaining optimal LL was validated by comparing the difference between ideal CobbL4-S1 and preoperative one with that between ideal CobbL4-S1 and postoperative one.
ResultsThe CobbL4-S1 was (36.17±1.53)° for ideal one, (22.57±5.50)° for preoperative one, (32.25±1.46)° for intraoperative one measured by Scoliometer software, and (34.43±1.72)° for postoperative one, respectively. The observed intraclass correlation coefficient (ICC) was excellent [ICC=0.96, 95% confidence interval (0.93, 0.97)] and the mean absolute difference (MAD) was low (MAD=1.23) between Scoliometer software and PACS system. The deviation between ideal CobbL4-S1 and postoperative CobbL4-S1 was (2.31±0.23)°, which was significantly lower than the deviation between ideal CobbL4-S1 and preoperative CobbL4-S1 (13.60±1.85)° (t=6.065, P=0.001).
ConclusionScoliometer software can help surgeon obtain the optimal LL and deserve further dissemination.
