BACKGROUND: Early repair of the ruptured cerebral aneurysm (RRCA), preferably within 24 hours of onset, is endorsed by clinical guideline as the preferred management strategy for patients with aneurysmal subarachnoid hemorrhage (aSAH). However, a comprehensive picture of this guideline-recommended usage in contemporary clinical practice is not available.
OBJECTIVE: This study aimed to characterize trends over time and practice variation in the implementation of an early RRCA strategy among patients with aSAH in a large, national representative data.
METHODS: Using data from the 2012-2019 National Inpatient Sample, we measured trends in the proportion of early RRCA, defined as within day 1 of admission, overall, and by demographic and geographical subgroups. Additionally, we created multilevel regression models to quantify hospital-level variation in the early RRCA rates.
RESULTS: We identified 82,615 aSAH hospitalizations (mean age, 56.1 years; 68.9% women) undergoing RRCA and, among these, 84.0% (95% CI, 83.4-84.7%) receiving early RRCA. The proportion of early RRCA increased steadily from 82.5% in 2012 to 85.8% in 2019 (P for trend <0.001). The proportion of patients receiving early RRCA across geographic regions ranged from 78.7% to 87.9%, with a median (IQR) of 84.2% (83.0-86.1%). In contrast, the delivery of early RRCA varied widely among hospitals, with a median (IQR) rate of 86.1% (75.0-100.0%) and a range from 0 to 100.0%. The median odds ratio for the early use of RRCA treatment was 1.24 (95% CI, 1.21-1.27) in 2019, indicating 24% increased odds of implementing early RRCA if moving from a lower-use to a higher-use hospital.
CONCLUSIONS: Most patients in the United States with aSAH received early RRCA treatment and exhibited an upward trend over the recent 8-year period. However, substantial variation in access to early RRCA was been observed across population subgroups, particularly at the hospital level. Future efforts are necessary to identify further sources of this variation and to develop initiatives that could represent an opportunity to optimize guideline-based quality of care in aSAH management.

UNASSIGNED: Gastrointestinal tumors represent a significant component of the cancer burden in Asia. This study aims to evaluate the burden of gastrointestinal tumors in Asia from 1990 to 2021 using data from the Global Burden of Disease Study 2021 (GBD 2021).
UNASSIGNED: The absolute incidence, mortality, and disability adjusted life years (DALYs) number and rate of six gastrointestinal tumors(colon and rectum cancer (CRC), stomach cancer (SC), pancreatic cancer (PC), esophageal cancer (EC), liver cancer (LC) and gallbladder and biliary tract cancer (GBTC)) in 48 Asian countries were extracted from GBD 2021. Differences were analyzed based on gender, age, year, location and socio-demographic index (SDI).
UNASSIGNED: In 2021, SC accounted for the highest disease burden in Asia (DALYs=16.41million [95% UI: 13.70, 19.62]). From 1990 to 2021, the age-standardized incidence rates of EC, LC, and SC in Asia declined, while the incidence rates of CRC and PC increased significantly, with CRC showing the largest rise (AAPC=1.08 [95% CI: 1.02 to 1.12]). Gastrointestinal tumors DALY rates peaked at age 70 and above, with males generally exhibiting higher rates than females. Furthermore, East Asia bears a higher burden compared to other Asian subregions. A higher SDI correlates with increased DALY rates for PC, but no linear relationship was observed for other gastrointestinal tumors.
UNASSIGNED: The burden of gastrointestinal tumors in Asia remains high and may continue to increase. Therefore, effective prevention and treatment measures are essential to address the challenge posed by gastrointestinal tumors.

UNASSIGNED: The aim of this research is to discuss the research status, hotspots, frontiers, and development trends in the field of small bowel adenocarcinoma based on bibliometrics and visual analysis by CiteSpace software.
UNASSIGNED: The relevant research articles on SBA from 1923 to 2023 were retrieved from the Web of Science Core Collection database. CiteSpace software was used to form a visual knowledge map and conduct analysis for the countries/regions, journals, authors, keywords, clusters, research hotspots and frontiers of the included articles.
UNASSIGNED: There were 921 articles included, and the number of articles published during 1923-2023 is increasing. The country with the highest number of articles published was the United States (443, 38.76%), followed by Japan (84, 9.12%) and France (72, 7.82%). The author with the highest number of publications is Ansell, Overman MJ (33, 3.58%), and the author with the highest co-citation frequency is Overman MJ (218). Journal of Clinical Oncology is the journal with the highest publication frequency. The top five cluster groups were \"chemotherapy\", \"inflammatory bowel disease\", \"celiac disease\", \"tumor\" and \"small intestine\". The related disease, chemotherapy drugs, and treatment regimens of SBA form the main research fields, and prognosis and diagnosis are the research hotspots and trends.
UNASSIGNED: The global research field in SBA has expanded in the past 100 years. The prognosis and new diagnosis of SBA are hotspots in this field and require further study in the future.

BACKGROUND: The analysis of the incidence trends of four autoimmune diseases (ADs) globally from 1990 to 2021, including rheumatoid arthritis (RA), inflammatory bowel disease (IBD), multiple sclerosis (MS), and psoriasis, reveals significant patterns of change, which further projects the incidence of these diseases at the global, regional, and national levels up to the year 2050.
METHODS: The estimates for the number of incident cases and age-standardized incidence rates (ASIR), along with the 95 % uncertainty intervals (UI) for RA, IBD, MS and psoriasis, were obtained from the Global Burden of Diseases Study 2021. The estimated annual percentage change (EAPC) was used to quantify the global incidence trends of these four ADs from 1990 to 2021. Additionally, a Bayesian age-period-cohort model was employed to project the number of new cases and incidence rates of these four ADs up to 2050.
RESULTS: From 1990 to 2021, the global ASIR of MS showed a declining trend (EAPC = -0.02 %, 95 % UI: -0.07 to 0.03), while the global ASIRs of IBD (EAPC = 0.29 %, 95 % UI: 0.20 to 0.38), RA (EAPC = 0.49 %, 95 % UI: 0.46 to 0.52), and psoriasis (EAPC = 0.23 %, 95 % UI: 0.21 to 0.26) demonstrated increasing trends. From 2022 to 2050, the global ASIRs of these four ADs are projected to rise, with the number of cases for all these conditions expected to continue increasing.
CONCLUSIONS: The global incidence trends and projected changes in ADs reveal that the burden of ADs is expected to continue growing in the future, underscoring the necessity for developing targeted policies to address this emerging challenge.

BACKGROUND: Between 2006 and 2017, antenatal care (ANC) coverage in Benin declined, potentially exacerbating inequalities and substantiating the need for health inequality monitoring. This study examines inequalities in ANC attendance in Benin, disaggregated by women\'s age, educational level, economic status, place of residence, region of residence, and the extent to which they have changed over time.
METHODS: Three rounds of the Benin Demographic and Health Surveys (2006, 2011-12, and 2017-18) were analyzed to examine inequalities in ANC coverage. An exploratory descriptive approach was adopted for the analysis. Simple [difference (D) and ratio (R)] and complex [population attributable risk (PAR) and population attributable fraction (PAF)] measures of inequalities were computed using the World Health Organization\'s Health Equity Assessment Toolkit (WHO\'s HEAT) online platform. The measures were computed separately for each of the three surveys, and their estimates were compared.
RESULTS: The findings revealed an 8.4% decline in at least four ANC visits between 2006 and 2017-18. The decline occurred irrespective of age, educational status, economic status, place of residence, and region. Region-related inequalities were the largest and increased slightly between 2006 (D = 54.6; R = 2.6; PAF = 47.8, PAR = 29.0) and 2017-18 (D = 55.8; R = 3.1; PAF = 57.2, PAR = 29.8). Education (2006: D = 31.3, R = 1.6, PAF = 40.5, PAR = 24.5; 2017-18: D = 25.2, R = 1.6, PAF = 34.9, PAR = 18.1) and rural-urban (2006: D = 16.8, R = 1.3, PAF = 17.8, PAR = 10.8; 2017-18: D = 11.2, R = 1.2, PAF = 13.1, PAR = 6.8) inequalities reduced while economic status inequalities did not improve (2006: D = 48, R = 2.2, PAF = 44.5, PAR = 26.9; 2017-18: D = 43.9, R = 2.4, PAF = 45.0, PAR = 23.4). Age inequalities were very minimal.
CONCLUSIONS: ANC inequalities remain deeply ingrained in Benin. Addressing their varying levels requires comprehensive strategies that encompass both supply-and demand-side interventions, focusing on reaching uneducated women in the poorest households and those residing in rural areas and Atacora.

BACKGROUND: While transcatheter edge-to-edge repair (TEER) with MitraClip is increasingly used, data on the risk stratification for assessing early mortality after this procedure are scarce.
OBJECTIVE: This study aimed to assess early mortality and analyze the risk factors of early mortality among patients who underwent TEER.
METHODS: Using the all-payer, nationally representative Nationwide Readmissions Database, our study included patients aged 18 years or older who had TEER between January 2017 and November 2020. We categorized the cohort into two groups depending on the occurrence of early mortality (death within 30 days after the procedure). Based on the ICD-10, we identified the trend of early mortality after TEER and further analyzed the risk factors associated with early mortality.
RESULTS: A total of 15,931 patients who had TEER were included; 292 (1.8 %) with early mortality and 15,639 (98.2 %) without. There was a decreasing trend in early mortality from 2.8 % in the first quarter of 2017 to 1.2 % in the fourth quarter of 2020, but it was not statistically significant (p = 0.18). In multivariable analysis, the independent risk factors for early mortality were chronic kidney disease not requiring dialysis (adjusted odds ratio [aOR]: 1.57; 95 % confidence interval [CI]: 1.11-2.22, p = 0.01), end-stage renal disease (aOR: 2.34; CI: 1.44-3.79, p < 0.01), chronic liver disease (aOR: 4.90; CI: 3.29-7.29, p < 0.01), coagulation disorder (aOR: 3.42; CI: 2.35-5.03, p < 0.01), systolic heart failure (aOR: 2.81; CI: 1.34-5.90, p < 0.01), diastolic heart failure (aOR: 2.69; CI: 1.24-5.84, p = 0.01) and unspecified heart failure (aOR: 3.23; CI: 1.49-7.01, p < 0.01). Among those who died during 30-day readmission following TEER, the most common cardiac cause and non-cardiac-cause of readmission were heart failure (18.2 %) and infection (26.6 %), respectively.
CONCLUSIONS: The early mortality following TEER was low at 1.8 %. The independent risk factors associated with early mortality were chronic kidney disease (including end-stage renal disease), chronic liver disease, coagulation disorder, and heart failure (both systolic and diastolic).

UNASSIGNED: With socioeconomic development, the increase of older pregnancies and multiparas has brought risks to mothers and infants.
UNASSIGNED: As parities increased, the proportion of women of advanced maternal age (AMA) and non-local domicile increased, while the proportion of women with higher education levels decreased. Women with ≥3 parities are more likely to have preterm birth (PTB) and macrosomia.
UNASSIGNED: A comprehensive analysis of pregnancy traits among women at different parities offers a robust foundation for tailored strategies against adverse pregnancy outcomes.

UNASSIGNED: This study analyzed long-term trends in the incidence of acute hepatitis B (AHB) in China, focusing on age, period, and cohort effects on incidence.
UNASSIGNED: Data on AHB from 2005 to 2021 were extracted from the National Notifiable Disease Reporting System (NNDRS) of China for analysis. Incidences of AHB were calculated by gender and age group using population denominators from the 2000, 2010, and 2020 censuses. Joinpoint regression was employed to evaluate trends, and an age-period-cohort model was used to assess the age, period, and cohort effects.
UNASSIGNED: The annual average incidence of reported AHB in children aged 14 years and below in low, intermediate, and high endemic areas decreased from 1.65, 2.33, and 2.56 per 100,000 in 2005-2010 to 0.56, 0.58, and 0.48 per 100,000 in the 2016-2021 period. The 15-39-year age group in high endemic areas exhibited the most significant decline in incidence, dropping from 23.14 per 100,000 in 2005 to 4.59 per 100,000 in 2021 among males and from 10.62 per 100,000 to 3.21 per 100,000 among females. Age-period-cohort analysis indicated decreasing age, period, and cohort effects for reported AHB incidence in each endemic area, except for a slight upward trend in the 15-19-year age group and in the cohort born between 1951 and 1955.
UNASSIGNED: This study demonstrated a rapid decline in AHB incidence across various endemic areas since 2005. Children aged 14 years and below exhibited very low AHB incidences, while the incidence among individuals over 15 years was higher. To further reduce AHB incidence, hepatitis B vaccine (HepB) coverage should be enhanced among adolescents and adults.

Objective weather classification methods have been extensively applied to identify dominant ozone-favorable synoptic weather patterns (SWPs), however, the consistency of different classification methods is rarely examined. In this study, we apply two widely-used objective methods, the self-organizing map (SOM) and K-means clustering analysis, to derive ozone-favorable SWPs at four Chinese megacities in 2015-2022. We find that the two algorithms are largely consistent in recognizing dominant ozone-favorable SWPs for four Chinese megacities. In the case of classifying six SWPs, the derived circulation fields are highly similar with a spatial correlation of 0.99 between the two methods, and the difference in the mean frequency of each SWP is less than 7%. The six dominant ozone-favorable SWPs in Guangzhou are all characterized by anomaly higher radiation and temperature, lower cloud cover, relative humidity, and wind speed, and stronger subsidence compared to climatology mean. We find that during 2015-2022, the occurrence of ozone-favorable SWPs days increases significantly at a rate of 3.2 day/year, faster than the increases in the ozone exceedance days (3.0 day/year). The interannual variability between the occurrence of ozone-favorable SWPs and ozone exceedance days are generally consistent with a temporal correlation coefficient of 0.6. In particular, the significant increase in ozone-favorable SWPs in 2022, especially the Subtropical High type which typically occurs in September, is consistent with a long-lasting ozone pollution episode in Guangzhou during September 2022. Our results thus reveal that enhanced frequency of ozone-favorable SWPs plays an important role in the observed 2015-2022 ozone increase in Guangzhou.

UNASSIGNED: Globally, the incidence rates of obesity and its related diseases, such as cardiovascular diseases and type 2 diabetes, are continuously rising, posing a significant public health challenge. Studies have indicated a potential correlation between vitamin D deficiency and obesity. However, a quantitative analysis of the studies related vitamin D and obesity is lacking. This investigation aims to fill this gap by providing a comprehensive bibliometric analysis to uncover the collaborative networks, research hotspots, and evolutionary trends within the field of vitamin D and obesity research.
UNASSIGNED: This study retrieved literature related to vitamin D and obesity from the Web of Science database spanning from 2000 to 2023. Bibliometric analysis was conducted using tools such as HistCite, VOSviewer, and CiteSpace to excavate multi-dimensional information including countries, institutions, authors, journals, citations, and keywords.
UNASSIGNED: A total of 6,144 records were retrieved, involving 123 countries, 6,726 institutions, and 28,156 authors, published in 1,551 journals. The number of published papers and citations showed a generally increasing trend. The United States led in terms of publication volume and influence, with journals such as Nutrients and Obesity Surgery having the highest publication counts. Nasser M. Al-Daghri was the most prolific and influential author. Keyword clustering revealed that research topics covered metabolic health, nutrition, immunity, and bariatric surgery. Citation burst analysis indicated a shift in research focus from the relationship between dietary calcium and obesity to the preventive effects of vitamin D supplementation on metabolic diseases.
UNASSIGNED: The application of bibliometric methods to analyze the research literature in the fields of obesity and vitamin D has provided a comprehensive understanding of the collaborative networks, key research focus, and evolutionary trends in this field, offering insights for guiding future research directions.
