Tetramethylpyrazine inhibits the inflammatory response by downregulating the TNFR1/IκB-α/NF-κB p65 pathway after spinal cord injury.

Previous studies have demonstrated that tetramethylpyrazine (TMP) can enhance the recovery of motor function in spinal cord injury (SCI) rats. However, the underlying mechanism involved in this therapeutic effect remains to be elucidated. We conducted RNA sequencing with a network pharmacology strategy to predict the targets and mechanism of TMP for SCI. The modified Allen's weight-drop method was used to construct an SCI rat model. The results indicated that the nuclear transfer factor-κB (NF-κB) pathway was identified through the Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis, and an inflammatory response was identified through the Gene Ontology (GO) enrichment analysis. Tumor necrosis factor (TNF) was identified as a crucial target. Western blotting revealed that TMP decreased the protein expression of TNF superfamily receptor 1 (TNFR1), inhibitor κB-α (IκB-α), and NF-κB p65 in spinal cord tissues. Enzyme-linked immunosorbent assay (ELISA) and immunohistochemistry (IHC) demonstrated that TMP inhibited TNF-α, interleukin-1ß (IL-1ß), reactive oxygen species (ROS), and malondialdehyde (MDA) expression and enhanced superoxide dismutase (SOD) expression. Histopathological observation and behavior assessments showed that TMP improved morphology and motor function. In conclusion, TMP inhibits inflammatory response and oxidative stress, thereby exerting a neuroprotective effect that may be related to the regulation of the TNFR1/IκB-α/NF-κB p65 signaling pathway.

Anchored sutures for fixation of the anterolateral thigh flap and prevention of orocutaneous fistula in oral and oropharyngeal cancer reconstruction.

OBJECTIVE: This study aims to assess the efficacy of anchored sutures (AS) in securing the anterolateral thigh (ALT) flap during oral and oropharyngeal reconstructions, and its impact on the occurrence of orocutaneous fistula (OCF). MATERIALS AND METHODS: A retrospective study was performed on patients who underwent ALT flap reconstruction in our department in the year 2022. The patients were divided into two groups based on whether the AS technique was used. The incidence of OCF was compared between the two groups, and AS-related complications were reported. Fisher's exact test was employed to assess the differences in baseline characteristics and the incidence of OCF between the two groups. RESULTS: The study included 214 patients, with 156 in the conventional suture (CS) group and 58 in the AS group. The incidence of OCF in the AS group was significantly lower compared to that in the CS group (P = 0.039). However, there was a weak correlation between OCF and the AS technique (φ = -0.149). Among the 58 cases in the AS group, three (5.17%) experienced AS-related granuloma (ASRG) as complications. CONCLUSION: The use of ALT flap reconstruction with the AS technique reduces the incidence of OCF; however, ASRG may be a potential complication. CLINICAL RELEVANCE: This study demonstrates the effectiveness of AS technique in securing ALT flaps, leading to a decreased risk of OCF in oral and oropharyngeal defect reconstruction.

Prevalence and risk factors of monoclonal gammopathy in patients with autoimmune inflammatory rheumatic disease: A systematic review and meta-analysis.

OBJECTIVE: To systemically investigate the prevalence and risk factors of monoclonal gammopathy (MG) in patients with autoimmune inflammatory rheumatic disease (AIIRD). METHODS: A literature search was conducted using databases of PubMed, EMBASE, and Web of Science for relevant studies from inception to 31 July 2021. The pooled prevalence, odds ratio (OR), weighted mean difference (WMD), and 95% confidence interval (CI) were calculated with Stata 16.0 using a random or fixed effects model. RESULTS: In 17 included studies involving 6667 AIIRD patients, the pooled prevalence of MG in AIIRD patients was 7% (95%CI: 0.06-0.09). Compared to general populations, patients with Sjögren's syndrome (SS) possessed the highest risk for MG (OR 4.51; 95%CI: 3.39-5.74), followed by systemic lupus erythematosus (OR 3.99; 95%CI: 2.84-5.14), ankylosing spondylitis (OR 2.04; 95%CI: 1.11-2.97), and rheumatoid arthritis (OR 2.00; 95%CI: 1.79-2.22). Older age (WMD = 5.17 years; 95%CI: 0.68-9.66), higher erythrocyte sedimentation rate (WMD = 14.04 mm/H; 95%CI: 7.77-20.30), higher serum gammaglobulins level (WMD = 1.92 mg/dl, 95%CI: 0.51-3.32) were associated with a greater risk of MG in AIIRD patients. CONCLUSIONS: MG prevalence was higher in AIIRD patients, especially in SS patients. Older age, higher erythrocyte sedimentation rate, and hypergammaglobulins were risk factors for MG in AIIRD patients.

Health Effects of Tobacco at the Global, Regional, and National Levels: Results From the 2019 Global Burden of Disease Study.

INTRODUCTION: The purpose was to quantify the health effects of tobacco using data from the 2019 Global Burden of Disease study. AIMS AND METHODS: We collected detailed information on tobacco consumption overall as well as its individual aspects (smoking, secondhand smoke, and chewing tobacco) for the deaths and disability-adjusted life years (DALYs) for all-cause disease, cardiovascular disease, neoplasms, and chronic respiratory diseases, and their age-standardized rates (ASRs). RESULTS: Tobacco was responsible for 8.71 million deaths and 229.77 million DALYs globally in 2019. The ASRs of all tobacco-related deaths and DALYs declined from 1990 to 2019, to 108.55 deaths per 100 000 population and 2791.04 DALYs per 100 000 population in 2019. During any year the ASRs of all tobacco-related deaths and DALYs were higher in males than in females. The ASRs of all tobacco-related deaths and DALYs were highest in countries with a low-middle sociodemographic index (SDI) and lowest in high-SDI countries in 2019. Cardiovascular disease, neoplasms, and chronic respiratory diseases were the three leading causes of tobacco-related mortality. CONCLUSIONS: Although the ASRs of deaths and DALYs related to tobacco have declined, the absolute number remain high. Tobacco control policies need to be strengthened further in order to reduce the heavy health burden of tobacco. IMPLICATIONS: This study provides a detailed description on the health effects of tobacco, including maps of the current global burden of tobacco-related disease. Although the ASRs of tobacco-related deaths and DALYs have declined, the absolute numbers remain high-tobacco was responsible for 8.71 million deaths and 229.77 million DALYs globally in 2019. The findings may have implications for tobacco control. Countries where progress has been slower in reducing tobacco-related disease burden should study and consider implementing policies and strategies that have been applied in countries like Singapore which show the greatest declines for recent decades.

Development and validation of a nomogram containing the prognostic determinants of chondrosarcoma based on the Surveillance, Epidemiology, and End Results database.

BACKGROUND: We aimed to develop and validate a reliable nomogram for predicting the disease-specific survival (DSS) of chondrosarcoma patients. METHODS: The Surveillance, Epidemiology, and End Results (SEER) database was queried from 2004 to 2015 to identify cases of histologically confirmed chondrosarcoma. Multivariate Cox regression analysis was performed to identify independent prognostic factors and construct a nomogram for predicting the 3- and 5-year DSS rates. Predictive values were compared between the new model and the American Joint Committee on Cancer (AJCC) staging system using concordance indexes (C-indexes), calibration plots, integrated discrimination improvement (IDI), net reclassification improvement (NRI), and decision curve analysis (DCA). RESULTS: Multivariate Cox regression identified 1180 patients, who were used to establish a nomogram based on a new model containing the predictive variables of age, socioeconomic status, tumor size, surgery status, chemotherapy status, and AJCC staging. In the nomogram, age at diagnosis is the factor with the highest risk, followed by AJCC stage IV and tumor size > 100 mm. Both the C-index and the calibration plots demonstrated the good performance of the nomogram. Moreover, both NRI and IDI were improved compared to the AJCC staging system, and also DCA demonstrated that the nomogram is clinically useful. CONCLUSION: We have developed a reliable nomogram for determining the prognosis and treatment outcomes of chondrosarcoma patients that is superior to the traditional AJCC staging system.

Lactate-driven type I collagen deposition facilitates cancer stem cell-like phenotype of head and neck squamous cell carcinoma.

Lactate is known to play a crucial role in the progression of malignancies. However, its mechanism in regulating the malignant phenotype of head and neck squamous cell carcinoma (HNSCC) remains unclear. This study found that lactate increases cancer stem cell (CSC) characteristics of HNSCC by influencing the deposition of type I collagen (Col I). Lactate promotes Col I deposition through two distinct pathways. One is to convert lactate to pyruvate, a substrate for Col I hydroxylation. The other is the activation of HIF1-α and P4HA1, the latter being a rate-limiting enzyme for Col I synthesis. Inhibition of these two pathways effectively counteracts lactate-induced enhanced cell stemness. Further studies revealed that Col I affects CSC properties by regulating cell cycle dynamics. In conclusion, our research proposes that lactate-driven Col I deposition is essential for the acquisition of CSC properties, and lactate-centric Col I deposition may be an effective target for CSCs.

Magnetic resonance imaging-based radiomics and deep learning models for predicting lymph node metastasis of squamous cell carcinoma of the tongue.

OBJECTIVE: This study aimed to establish a combined method of radiomics and deep learning (DL) in magnetic resonance imaging (MRI) to predict lymph node metastasis (LNM) preoperatively in patients with squamous cell carcinoma of the tongue. STUDY DESIGN: In total, MR images of 196 patients with lingual squamous cell carcinoma were divided into training (n = 156) and test (n = 40) cohorts. Radiomics and DL features were extracted from MR images and selected to construct machine learning models. A DL radiomics nomogram was established via multivariate logistic regression by incorporating the radiomics signature, the DL signature, and MRI-reported LN status. RESULTS: Nine radiomics and 3 DL features were selected. In the radiomics test cohort, the multilayer perceptron model performed best with an area under the receiver operating characteristic curve (AUC) of 0.747, but in the DL cohort, the best model (logistic regression) performed less well (AUC = 0.655). The DL radiomics nomogram showed good calibration and performance with an AUC of 0.934 (outstanding discrimination ability) in the training cohort and 0.757 (acceptable discrimination ability) in the test cohort. The decision curve analysis demonstrated that the nomogram could offer more net benefit than a single radiomics or DL signature. CONCLUSION: The DL radiomics nomogram exhibited promising performance in predicting LNM, which facilitates personalized treatment of tongue cancer.

Dysregulated Wnt/ß-catenin signaling confers resistance to cuproptosis in cancer cells.

Cuproptosis is characterized by the aggregation of lipoylated enzymes of the tricarboxylic acid cycle and subsequent loss of iron-sulfur cluster proteins as a unique copper-dependent form of regulated cell death. As dysregulation of copper homeostasis can induce cuproptosis, there is emerging interest in exploiting cuproptosis for cancer therapy. However, the molecular drivers of cancer cell evasion of cuproptosis were previously undefined. Here, we found that cuproptosis activates the Wnt/ß-catenin pathway. Mechanistically, copper binds PDK1 and promotes its interaction with AKT, resulting in activation of the Wnt/ß-catenin pathway and cancer stem cell (CSC) properties. Notably, aberrant activation of Wnt/ß-catenin signaling conferred resistance of CSCs to cuproptosis. Further studies showed the ß-catenin/TCF4 transcriptional complex directly binds the ATP7B promoter, inducing its expression. ATP7B effluxes copper ions, reducing intracellular copper and inhibiting cuproptosis. Knockdown of TCF4 or pharmacological Wnt/ß-catenin blockade increased the sensitivity of CSCs to elesclomol-Cu-induced cuproptosis. These findings reveal a link between copper homeostasis regulated by the Wnt/ß-catenin pathway and cuproptosis sensitivity, and suggest a precision medicine strategy for cancer treatment through selective cuproptosis induction.

A METTL3 Inhibitor Alleviates the Onset of Osteomyelitis in a Mouse Model by Targeting MyD88.

We aimed to study the effects of a methyltransferase 3 (METTL3) inhibitor on osteomyelitis. Bone marrow cells (BMs) and peripheral blood mononuclear cells (PBMCs) were isolated from osteomyelitis patients at our hospital. Primary BM-derived macrophages (BMDMs) were incubated with lipopolysaccharide (LPS), poly(I:C), or PAM3CSK4 after pretreatment with STM2457. S. aureus was injected into the intramedullary canal to construct an osteomyelitis C57BL/6 mice model, which was then treated with STM2457. Body weights, µCT three-dimensional analyses, and bacterial burdens of the mice were obtained. Up-regulated METTL3 expression was found in both BMs and PBMCs of osteomyelitis patients. LPS and PAM3CSK4-induced IL-6 and TNF-α secretion in BMDMs could be inhibited by STM2457 pretreatment, while STM2457 pretreatment did not affect the relative expression of NOS2, IL-6, and TNF-α after incubation with poly(I:C). STM2457 alleviated the symptoms of osteomyelitis in mice with increased body weights, diminished reactive bone formation and cortical bone loss, increased bacterial burdens, and decreased IL-6 and TNF-α secretion. STM2457 pretreatment down-regulated the relative expression of myeloid differentiation factor 88 (MyD88), p-TAK, and p-IKKα/ß in LPS-stimulated BMDMs, while it did not show any effect on poly(I:C)-stimulated BMDMs. STM2457 alleviates the onset of osteomyelitis in mice by down-regulating the relative expression of MyD88 and NF-κB relevant inflammation molecules in macrophages.

Thiopental sodium attenuates hypoxia/reoxygenation-induced injury in osteoblasts by modulating AKT signaling.

Thiopental sodium (TPTS) is a barbiturate general anesthetic, while its effects on hypoxia/reoxygenation (H/R)-induced injury are still unclear. This study aimed to investigate whether TPTS exerts protective effects against the H/R-induced osteoblast cell injury and explore the underlying mechanisms. Osteoblast cell injury model was induced by the H/R condition, which was treated with or without TPTS. Cell viability and lactate dehydrogenase (LDH) release were determined by the corresponding commercial kits. The levels of oxidative stress were determined in the experimental groups. Cell apoptosis and Caspase-3 activities were determined by propidium iodide staining and substrate-based assay, respectively. Western blotting and qRT-PCR were performed to measure the mRNA and protein levels, respectively. Treatment with TPTS was able to increase cell viability and reduce LDH release in H/R-induced osteoblasts. Additionally, TPTS regulated oxidative stress in H/R-induced osteoblasts by suppressing malondialdehyde (MDA) and reactive oxygen species (ROS) as well as boosting superoxide dismutase (SOD). TPTS was able to suppress cell apoptosis by suppressing Caspase-3 activity and cleavage. TPTS exerted protective effects against cell injury and apoptosis induced by the H/R conditions, which were associated with its regulation of Akt signaling. Moreover, TPTS induced osteoblast differentiation under the H/R condition. In summary, TPTS attenuates H/R-induced injury in osteoblasts by regulating AKT signaling.

The impact of different nursing skill mix models on patient outcomes in a respiratory care center.

BACKGROUND: Many hospitals have reformed hospital policies and changed nursing models to cope with shortages in nursing staff and control medical costs. However, the nursing skill mix model that most successfully achieves both cost effectiveness and quality care has yet to be determined. AIM: The aim of this study was to explore the impact of different nurse staffing models on patient outcomes in a respiratory care center (RCC). METHODS: Retrospective data from 2006 to 2008 were obtained from records monitoring nursing care quality, as well as patient records and nursing personnel costs in an RCC as a medical center, in southern Taiwan. A total of 487 patients were categorized into two groups according to the RCC's mix of nursing staff. The "RN/Aide" group comprised 247 patients who received RN and aide care, with a 0.7-0.8 proportion of RNs, from July 2006 to June 2007. The other 240 patients ("All-RN") received 100% RN care from January 2008 to December 2008. RESULTS: The results of this study indicated no significant differences in occurrence of pressure ulcer or respiratory tract infections, days of hospitalization, mortality, or nursing costs. However, significant differences were observed in ventilator weaning and occurrence of urinary tract and bloodstream infections. CONCLUSIONS: A higher proportion of RNs was associated not only with a lower rate of urinary tract infection but also with more patients being weaned successfully from ventilators. The findings of this study have implications for how managers and administrators manage nurse staffing in respiratory care.

Luminescent Lifetime Regulation of Lanthanide-Doped Nanoparticles for Biosensing.

Lanthanide-doped nanoparticles possess numerous advantages including tunable luminescence emission, narrow peak width and excellent optical and thermal stability, especially concerning the long lifetime from microseconds to milliseconds. Differing from other shorter-lifetime fluorescent nanomaterials, the long lifetime of lanthanide-doped nanomaterials is independent with background fluorescence interference and biological tissue depth. This review presents the recent advances in approaches to regulating the lifetime and applications of bioimaging and biodetection. We begin with the introduction of the strategies for regulating the lifetime by modulating the core-shell structure, adjusting the concentration of sensitizer and emitter, changing energy transfer channel, establishing a fluorescence resonance energy transfer pathway and changing temperature. We then summarize the applications of these nanoparticles in biosensing, including ion and molecule detecting, DNA and protease detection, cell labeling, organ imaging and thermal and pH sensing. Finally, the prospects and challenges of the lanthanide lifetime regulation for fundamental research and practical applications are also discussed.

Global, regional, and national burden of periodontitis from 1990 to 2019: Results from the Global Burden of Disease study 2019.

BACKGROUND: To evaluate the prevalence and incidence of periodontitis and associated disability-adjusted life years (DALYs) from 1990 to 2019. METHODS: We collected data on periodontitis between 1990 and 2019 from the Global Burden of Disease (GBD) 2019 Study. The global prevalence, incidence, and DALYs attributed to periodontitis were analyzed. The age-standardized rate (ASR) and estimated annual percentage changes (EAPCs) were calculated to quantify the burden of the disease and temporal trends. RESULTS: The ASR of the prevalence, incidence, and DALYs increased worldwide from 1990 to 2019. In 2019, Western Sub-Saharan Africa carried the heaviest burden of periodontitis, whereas the nation with the highest periodontitis burden was Gambia. The burden of periodontitis was negatively associated with the level of socioeconomic development. Although, the majority of periodontitis burden was observed among those aged 55-59 years, the incidence of periodontitis has shown an increasing trend among younger individuals. CONCLUSION: Periodontitis continues to be a global public health problem. Current prevention and control strategies should be enhanced to prevent an increase in periodontitis.

The expression of ADAM23 and its correlation with promoter methylation in non-small-cell lung carcinoma.

ADAM23, a member of a disintegrin and metalloprotease (ADAM) family, has been reported to be expressed in several types of tumours. The exact role of ADAM23 and the possible mechanisms in which it is involved in non-small-cell lung carcinoma (NSCLC) remains unclear. Therefore, this study was designed to explore the expression of ADAM23 and its correlation with promoter methylation in NSCLC. Immunohistochemistry and RT-PCR together with Western blotting methods were used to analyse the expression of ADAM23 in 52 cancer tissue samples and eight benign pulmonary lesions as well as four cell lines. The methylated status of ADAM23 gene was determined with methylation-specific PCR (MSP). The results of immunohistochemistry showed that the expression of ADAM23 protein was lower in NSCLC than that in corresponding normal tissues and benign pulmonary lesions (38.5%vs. 86.5% and 87.5%, P < 0.05), and decreased as NSCLC progressed. Meanwhile, methylation of ADAM23 gene was observed in 21 of 52 NSCLC tissues (40.4%), much higher than that of adjacent normal tissues (7.6%) and benign pulmonary lesions (0/8). In the cancer tissues of ADAM23-negative samples, the rate of ADAM23 gene methylation was 50.3% (17/32). ADAM23 expression and its promoter methylation were negatively associated (r = -0.328, P = 0.017). Moreover, weak expression of ADAM23 in methylated cancer cells increased after treatment with 5-aza-2'-deoxycytidine (5-Aza-2'-dC), confirming that methylation was responsible for the gene downregulation. Our results demonstrate that the expression level of ADAM23 is likely to be involved in the progression of NSCLC and its downregulation is probably correlated with promoter methylation. These findings may provide potential diagnostic and prognostic information about NSCLC.

Dye Sensitization for Ultraviolet Upconversion Enhancement.

Upconversion nanocrystals that converted near-infrared radiation into emission in the ultraviolet spectral region offer many exciting opportunities for drug release, photocatalysis, photodynamic therapy, and solid-state lasing. However, a key challenge is the development of lanthanide-doped nanocrystals with efficient ultraviolet emission, due to low conversion efficiency. Here, we develop a dye-sensitized, heterogeneous core-multishelled lanthanide nanoparticle for ultraviolet upconversion enhancement. We systematically study the main influencing factors on ultraviolet upconversion emission, including dye concentration, excitation wavelength, and dye-sensitizer distance. Interestingly, our experimental results demonstrate a largely promoted multiphoton upconversion. The underlying mechanism and detailed energy transfer pathway are illustrated. These findings offer insights into future developments of highly ultraviolet-emissive nanohybrids and provide more opportunities for applications in photo-catalysis, biomedicine, and environmental science.

Sclerosing polycystic adenosis of the submandibular gland: Two case reports.

BACKGROUND: Sclerosing polycystic adenosis (SPA) is a rare disease of salivary glands, similar to fibrocystic disease of the breast. It occurs over a wide age range and exhibits a slight female preference. Most SPA cases have occurred in the parotid gland. The exact nature of SPA is unclear, but its tumor nature has recently been proposed. Although SPA has a good prognosis after adequate surgery, atypical lesions might occur, ranging from mild dysplasia to carcinoma in situ in some cases. To the best of our knowledge, only five cases of SPA in the submandibular gland have been reported to date. Here, we present two new cases of SPA involving the submandibular gland. CASE SUMMARY: A 50-year-old woman and a 52-year-old woman were referred to Tongji Hospital in Wuhan, China, with complaints of moderate pain, recurrent swelling, and a mass in the submandibular area. After admission, the two cases of the submandibular mass were examined physically. The boundary of the submandibular tumor was clear, and the range of motion was good. After preoperative examinations, surgery was performed on a selective basis. Postoperative histopathological examination revealed a well-defined mass with acinar structures, ducts, or cystic dilated glands of various sizes scattered in a large number of proliferative sclerosing stroma. There were flat and cuboidal cells, and eosinophils in the duct epithelium. There was also a eosinophilic substance in the lumen of dilated cysts. No atypical epithelial hyperplasia, invasive growth, or carcinoma in situ was found. Based on the above findings, the mass was diagnosed as SPA. Both patients have remained asymptomatic and no recurrence or distant metastasis had occurred by the 7-mo and 5-year follow-up, respectively. CONCLUSION: SPA is a rare disease of the salivary gland. Even though it has a good prognosis after adequate surgery, atypical lesions may occur from mild dysplasia to carcinoma in situ. However, no recurrence, distant metastasis, or mortality has been reported for submandibular gland SPA. Clinicians and pathologists should be familiar with the characteristics of SPA in the submandibular gland to avoid misdiagnosis and overtreatment.

Early prediction of mortality risk among patients with severe COVID-19, using machine learning.

BACKGROUND: Coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 infection, has been spreading globally. We aimed to develop a clinical model to predict the outcome of patients with severe COVID-19 infection early. METHODS: Demographic, clinical and first laboratory findings after admission of 183 patients with severe COVID-19 infection (115 survivors and 68 non-survivors from the Sino-French New City Branch of Tongji Hospital, Wuhan) were used to develop the predictive models. Machine learning approaches were used to select the features and predict the patients' outcomes. The area under the receiver operating characteristic curve (AUROC) was applied to compare the models' performance. A total of 64 with severe COVID-19 infection from the Optical Valley Branch of Tongji Hospital, Wuhan, were used to externally validate the final predictive model. RESULTS: The baseline characteristics and laboratory tests were significantly different between the survivors and non-survivors. Four variables (age, high-sensitivity C-reactive protein level, lymphocyte count and d-dimer level) were selected by all five models. Given the similar performance among the models, the logistic regression model was selected as the final predictive model because of its simplicity and interpretability. The AUROCs of the external validation sets were 0.881. The sensitivity and specificity were 0.839 and 0.794 for the validation set, when using a probability of death of 50% as the cutoff. Risk score based on the selected variables can be used to assess the mortality risk. The predictive model is available at [https://phenomics.fudan.edu.cn/risk_scores/]. CONCLUSIONS: Age, high-sensitivity C-reactive protein level, lymphocyte count and d-dimer level of COVID-19 patients at admission are informative for the patients' outcomes.

Global, regional, and national burden of nasopharyngeal carcinoma from 1990 to 2017-Results from the Global Burden of Disease Study 2017.

BACKGROUND: The aim of this study is to estimate the incidence, mortality, and disability-adjusted life years (DALYs) of nasopharyngeal carcinoma from 1990 to 2017. METHODS: We collected detailed information on nasopharyngeal carcinoma from 1990 to 2017 based on data from Global Burden of Disease (GBD) study 2017. The global incidence, mortality, and DALYs attributable to nasopharyngeal carcinoma was reported, as well as the age-standardized rates (ASRs). RESULTS: The ASR of nasopharyngeal carcinoma incidence decreased from 1.88 (95% UI: 1.76-2.00) in 1990 to 1.35 (95% UI: 1.28-1.42) in 2017. The ASR of mortality decreased from 1.19 (95% UI: 1.13-1.25) in 1990 to 0.86 (95% UI: 0.82-0.89) in 2017, while ASR-DALYs decreased from 38.2 (95% UI: 35.9-40.2) in 1990 to 25.4 (95% UI: 24.4-26.5) in 2017. CONCLUSIONS: The ASR of incidence, mortality, and DALYs of nasopharyngeal carcinoma have decreased slightly worldwide. East Asia carried the heaviest burden of nasopharyngeal carcinoma. The majority of nasopharyngeal carcinoma burden was observed in men, especially among male aged 55 to 69 years.

Trends in disease burden of chronic myeloid leukemia at the global, regional, and national levels: a population-based epidemiologic study.

BACKGROUND: Outcomes of chronic myeloid leukemia (CML) has been improved dramatically in the past two decades, but survival levels of CML patients varied in regions. Comprehensive epidemiological research is necessary to evaluate the global burden of CML. METHODS: All data used in our study came from the Global Burden of Disease (GBD) study 2017. Incidence cases, death cases, disability-adjusted life-years (DALYs), and its corresponding age-standardized rate between 1990 to 2017 were used to describe the distribution of CML burden, according to age, sex, social-demographic index (SDI), and countries. Data about attributable risk factors contributing to CML deaths and DALYs were also extracted and analyzed. RESULTS: Globally, the disease burden of CML gradually decreased from 1990 to 2017. Higher SDI countries achieved a remarkable effect on diminishing the CML burden. Conversely, due to population growth, the incidence cases, death cases, and DALYs of CML in lower SDI quintiles showed an upward trend. India had the most incidence cases and death cases of CML in the world. Additionally, smoking was the most significant attributable risk factor contributing to CML deaths and DALYs, followed by high body mass index. CONCLUSION: The disease burden of CML decreased globally, especially in higher SDI countries in the past 28 years. The increasing incidence cases and death cases were mainly observed in lower SDI countries. Additionally, strategies to control modifiable risk factors such as smoking and high body mass index might be useful in diminishing mortality and DALYs.
