Catheter-Directed Therapies for Deep Vein Thrombosis and Pulmonary Embolism: Nationwide Trends in Medicare Part B Patients from 2015 to 2021

Abstract Background Nationwide trends in the utilization of catheter-directed therapies for deep vein thrombosis and pulmonary embolism in the Medicare population are essential as they represent a major health care challenge. The annual incidence and mortality with venous thromboembolism are around 900,000 and 60,000 to 100,000 patients, respectively, in the United States. Methods Data were acquired from the Data.CMS.gov website on Physician/Supplier Procedure Summary with a list of Medicare Part B fee-for-service claims from 2015 to 2021. Current Procedural Terminology codes 37187 (percutaneous venous mechanical thrombectomy) and 37212 (thrombolytic venous therapy) were queried for deep vein thrombosis. Similarly, Current Procedural Terminology codes 37184 (percutaneous arterial mechanical thrombectomy) and 37211 (thrombolytic arterial therapy) were queried for pulmonary embolism. Annual procedure counts, site of service, and self-reported specialty of the operator were recorded. Results Overall, there was a trend toward increasing utilization of thrombectomy and decreasing utilization of thrombolysis procedures for both deep vein thrombosis and pulmonary embolism. Radiologists performed the majority of the catheter-directed therapy interventions for deep vein thrombosis, while radiologists and surgeons performed a similar number of catheter-directed therapy procedures for pulmonary embolism. Cardiologists were third in the catheter-directed therapy procedure count for both deep vein thrombosis and pulmonary embolism. Conclusion An analysis of nationwide trends from 2015 to 2021 suggests increasing utilization of thrombectomy starting in 2020 when compared to thrombolysis for catheter-directed therapies for both deep vein thrombosis and pulmonary embolism procedures. Newer thrombectomy technologies may be one of the drivers of this shift from thrombolysis to thrombectomy.

The incidence, mortality and disease burden of cardiovascular diseases in China: a comparative study with the United States and Japan based on the GBD 2019 time trend analysis

BackgroundCardiovascular diseases (CVDs) are not only the primary cause of mortality in China but also represent a significant financial burden. The World Health Organization highlight that as China undergoes rapid socioeconomic development, its disease spectrum is gradually shifting towards that of developed countries, with increasing prevalence of lifestyle-related diseases such as ischemic heart disease and stroke. We reviewed the rates and trends of CVDs incidence, mortality and disability-adjusted life years (DALYs) burden in China and compared them with those in the United States (US) and Japan for formulating CVDs control policies.MethodsData on CVDs incidence, death and DALYs in China, the US and Japan were obtained from the GBD 2019 database. The Joinpoint regression model was used to analyze the trends in CVDs incidence and mortality in China, the US and Japan, calculate the annual percentage change and determine the best-fitting inflection points.ResultsIn 2019, there were approximately 12,341,074 new diagnosed cases of CVDs in China, with 4,584,273 CVDs related deaths, causing 91,933,122 DALYs. The CVDs age-standardized incidence rate (ASIR) in China (538.10/100,000) was lower than that in the US and globally, while age-standardized death rate (ASDR) (276.9/100,000) and age-standardized DALY rate (6,463.47/100,000) were higher than those in the two regions. Compared with the US and Japan, from 1990 to 2019, the CVDs incidence rate in China showed an increasing trend, with a lower annual decrease in ASDR and a younger age structure of disease burden. Furthermore, the disease spectrum in China changed minimally, with stroke, ischemic heart disease, and hypertensive heart disease being the top three leading CVDs diseases in terms of incidence and disease burden, also being the major causes of CVDs in the US and Japan.ConclusionThe prevention and control of CVDs is a global issue. The aging population and increasing unhealthy lifestyles will continue to increase the burden in China. Therefore, relevant departments in China should reference the established practices for CVDs control in developed countries while considering the diversity of CVDs in different regions when adjusting national CVDs control programs.

Eco-Environmental Assessment and Trend Analysis of the Yangtze River Middle Reaches Megalopolis Based on a Modified Remote Sensing Ecological Index

China’s accelerating pace of urbanization has placed severe pressure on its ecosystems. Hence, the monitoring and assessment of eco-environmental quality has significant implications for sustainable urban development. By introducing a pollution index, a modified remote sensing ecological index (MRSEI) was constructed to more comprehensively evaluate the spatiotemporal distribution of the eco-environment quality in the middle reaches of the Yangtze River where urbanization has been developing rapidly. Future trends in eco-environmental quality were analyzed using Theil–Sen trend analysis, the Mann–Kendall test, and the Hurst exponent. Environmental influencing factors were also analyzed. Our results show that: (1) The impact of pollution factors on urban agglomerations cannot be overlooked. The MRSEI model introduces a pollution indicator to better assess the eco-environmental quality of urban agglomeration areas. (2) The eco-environmental quality is high in the south and east and low in the north and west, with overall levels ranging between moderate and good. (3) The eco-environmental quality remained stable, improved, and degraded in 86.3%, 3.1%, and 10.7% of the study area, respectively. (4) The land use and land cover type are directly related to the eco-environment. Climate factors indirectly affect the eco-environment. Human activities in cities and urban peripheries lead to land use changes and industrial pollution, which significantly affect environmental quality.

Genital gender-affirming surgery trends in Germany: Total population data with 19,600 cases from 2006 to 2022.

To delineate the current trends regarding gender-affirming surgeries (GAS) in Germany. Analysis of German hospital quality reports from 2006 to 2022 was conducted using the reimbursement.info tool. The German procedure classification (OPS) codes 5-646.0 for masculinizing- and 5-646.1 for feminizing surgery were assessed to identify GAS. Linear regression models were utilized for the analysis and depiction of current trends. A total of 19,632 gender-affirming procedures were performed during the study period with an exponential increase over the years. Masculinizing surgeries increased from 246 in 2006 to 1291 cases in 2022 (increase by 424%; p<0.001). The highest annual increase of 37.2% in numbers was from 2018 to 2019 (from 1235 to 1694 cases). Feminizing surgeries increased from 180 cases in 2006 to 799 procedures in 2022 (increase by 343%; p<0.001). The cases increased most between 2015 and 2016 from 277 to 502 cases (81.2%). The number of hospitals offering these surgeries expanded from 24 in 2006 to 29 in 2022 (21% increase; p<0.001). This study demonstrates an exponential growth in numbers feminizing and masculinizing of GAS performed each year in Germany. Furthermore, a discernible trend emerges with a propensity for concentration of procedures within selected high-caseload centers across Germany.

Reimagining, Repositioning, Rebordering: Intersections of the Biopolitical and Geopolitical in the UK's Post-Brexit Migration Regime (and Why It Matters for Migration Research)

This article examines the emergence of a new immigration regime in the United Kingdom, following its exit from the European Union, to uncover the entanglements and intersections of biopolitics, geopolitics and ideology in migration and migration governance. It draws a clear line between Brexit as a political and geopolitical rupture, the ideological project of “Global Britain” that emerged from it, and the forms of migrant and citizen subjectivity that these paired projects produced as the body politic was re-modelled in this image. It demonstrates this through a critical analysis of recent immigration data and trends that consider who is coming to the UK, through what routes and under what conditions, and of recently introduced changes to the immigration system, including the curtailment of asylum and the emergence of new humanitarian routes. Building on scholarship that has shown the impact of migration on the outcome of the 2016 Brexit referendum, our analysis of migration and migration governance after Brexit offers unique insights into how migration continues to play a central role in the ideological reimagining and geopolitical repositioning of the UK on the global stage and develops the concept of rebordering to capture the nexus between ideological and geopolitical transformations and the making — through migration and migration governance — of a new body politic and its “others” that embody and can serve their purposes.

Analysis and mapping of global research publications on migrant domestic workers

Recognizing the importance of evidence-based research in informing migration policies and empowering migrant domestic workers (MDWs), this study aims to provide a comprehensive analysis of MDW research patterns and trends. Using a descriptive cross-sectional study design, research articles on MDWs were retrieved from the Scopus database. The findings reveal a substantial increase in research output in recent years, with notable contributions from journals in the fields of social sciences and humanities. Key contributors include scholars from the United States, the United Kingdom, and institutions such as the National University of Singapore and the Chinese University of Hong Kong. Journals in the field of migration have prominent role in publishing research on MDWs. At the author level, Yeoh, B.S.A, at the National University of Singapore was the most prolific author. Academic activities were the main driver of research and that funding was suboptimal in this field. Highly cited articles focused on topics such as transnational motherhood, the international division of reproductive labor, and the negotiation of citizenship rights. Major research hotspots in the retrieved articles included mental health aspects, caregiving especially of the elderly, and struggles for legal rights. Specific nationalities, such as Filipina/o and Indonesian MDWs, have been the focus of numerous studies, shedding light on their narratives, challenges, and agency within transnational contexts. Overall, this study underscores the urgency of addressing the needs and rights of MDWs, advocate for human rights, and enhance understanding of occupational health and safety in the unique context of domestic work.

Cluster B personality disorders and psychotropic medications: a focused analysis of trends and patterns across sex and age groups.

This study investigated sex and age differences in patterns of psychotropic medication use before and after the initial diagnosis of Cluster B personality disorders (PDs) and analyzed trends over time. Analyzing data from the Quebec Integrated Chronic Disease Surveillance System for individuals newly diagnosed with Cluster B PD (≥ 14 years) between 2002 and 2018 and under the provincial public drug plan, we calculated yearly and monthly proportions of individuals exposed to psychotropic medications during the year before and after their diagnosis by sex and age. Robust Poisson regression models assessed the association between sex and exposure to psychotropic medications after the diagnosis of Cluster B PD. Among 87,778 individuals with a first Cluster B PD diagnosis (mean age: 44.5 years; 57.5% women), the proportion of users increased post-diagnosis. Notably, after diagnosis, females were more likely to receive psychiatric medications (between 78.9% and 83.7% during the study period vs. 72.8% and 76.8%). Males were less likely than females to receive antidepressants (adjusted prevalence ratio (aPR): 0.83; 99% confidence interval (CI): 0.82-0.85) and anxiolytics (aPR: 0.86; 99%CI: 0.84-0.88), whereas they had higher exposure to antipsychotics (aPR: 1.04; 99%CI: 1.02-1.06) and ADHD medications (aPR: 1.14; 99%CI: 1.07-1.2). Age-specific trends showed increased ADHD medication use among younger patients (14-24 years), and anxiolytic use predominated in those aged ≥ 65 years. Psychotropic medication use was high among Cluster B PD patients, with differences in medication classes according to age and sex. The marked sex and age differences in psychotropic medication use among Cluster B PD patients underscore the need for a sex-sensitive and age-specific approach in psychiatric care.

Analysis of third and fourth corneal high-order aberrations before and after small incision lenticule extraction (SMILE) in myopic and myopic astigmatic eyes using ray tracing aberrometry

BackgroundAim is to analyze alterations in third and fourth corneal higher-order aberrations using a ray tracing aberrometer (iTrace) induced by SMILE (small incision lenticule extraction) refractive surgery on Algerian patients; and also to investigate how corneal aberrations vary with spherical equivalent (SE), corneal central thickness (CCT), and age. Design Prospective, non-randomized case series that were carried out at the Chiali Smile Center, Algiers, Algeria.ParticipantsA total of 219 eyes from 110 myopic patients, with and without astigmatism, successfully concluded the ultimate follow-up. Participants exhibited an average age of 32.48 years, with preoperative mean corneal high-order aberrations (CHOA) measuring 0.005 ± 0.036 μm.MethodsA tracking trend analysis of high-order aberrations (HOAs) was conducted on the three groups of patients, assessing total corneal high-order aberrations after SMILE over periods of two, six, and twelve months.ResultsA substantial increase in total corneal high-order aberrations following SMILE, with a P value < 0.05. Conversely, there was a noteworthy and significant decrease in vertical trefoil for all groups (P value = 0.000). Interestingly, the corneal higher-order aberrations were more pronounced after two months compared to the six and twelve-month intervals. Spherical aberration demonstrated a significant increase with the extent of preoperative myopia and preoperative spherical equivalent both before and after SMILE surgery (P < 0.05), particularly in cases of high myopia. Moreover, there were significant reductions in preoperative and postoperative vertical coma (P = 0.047, P = 0.004, respectively) corresponding to the degree of preoperative myopia, with a more substantial decrease in vertical coma observed in cases of low myopia.ConclusionIn the post-SMILE period, a notable increase in vertical coma and spherical aberrations was observed, accompanied by a significant decrease in vertical trefoil across all eyes. These aberration changes were identified to be closely associated with the spherical equivalent.

TBI related death has become the new epidemic in polytrauma: a 10-year prospective cohort analysis in severely injured patients.

Advances in trauma care have attributed to a decrease in mortality and change in cause of death. Consequently, exsanguination and traumatic brain injury (TBI) have become the most common causes of death. Exsanguination decreased by early hemorrhage control strategies, whereas TBI has become a global health problem. The aim of this study was to investigate trends in injury severity,physiology, treatment and mortality in the last decade. In 2014, a prospective cohort study was started including consecutive severely injured trauma patients > 15years admitted to a Level-1 Trauma Center ICU. Demographics,physiology,resuscitation, and outcome parameters were prospectively collected. Five hundred and seventy-eight severely injured patients with predominantly blunt injuries (94%) were included. Seventy-two percent were male with a median age of 46 (28-61) years, and ISS of 29 (22-38). Overall mortality rate was 18% (106/578) with TBI (66%, 70/106) being the largest cause of death. Less than 1% (5/578) died of exsanguination. Trend analysis of the 10-year period revealed similar mortality rates despite an ISS increase in the last 2years. No significant differences in demographics,and physiology in ED were noted. Resuscitation strategy changed to less crystalloids and more FFP. Risk factors for mortality were age,brain injury severity,base deficit,hypoxia,and crystalloid resuscitation. TBI was the single largest cause of death in severely injured patients in the last decade. With an aging population TBI will increase and become the next epidemic in trauma. Future research should focus on brain injury prevention and decreasing the inflammatory response in brain tissue causing secondary damage, as was previously done in other parts of the body.

Diatom silicon isotope ratios in Quaternary research: Where do we stand?

Silicon stable isotope ratios (expressed as δ30Si) in biogenic silica have been widely used as a proxy for past and present biogeochemical cycling in both marine and lacustrine settings, in particular for nutrient utilization reconstructions. Yet an analysis of publication trends suggests a significant decline in the application of δ30Si to Quaternary science questions in the last five years. At the same time as δ30Si proxy applications have decreased, we are learning more about its complexities: an expanding body of work is highlighting biases, caveats or complications involved in the application of δ30Si-based approaches to the sediment record. These include the demonstration of species-specific silicon isotope fractionation factors (i.e. ‘vital effects’) or the potential for Fe or other trace metals to influence silicon isotope fractionation. Others have inferred the potential of biogenic silica dissolution to alter an initial δ30Si value, or questioned the preservation of the initial δ30Si through early diagenetic processes more generally. Another challenge receiving more attention is centered around deconvolving a δ30Si-value into a signal reflecting biological productivity and a signal reflecting changes in the δ30Si of dissolved silicon driven by whole-system and/or circulation changes. Finally, a number of studies focus on analytical difficulties, especially during sample preparation related to achieving and demonstrating a contaminant free biogenic silica. These challenges lead us to posit that the Quaternary science community is moving away from silicon isotope proxies because they are losing confidence in their reliability and usefulness. Here, focusing on the diatoms – the dominant biosilicifiers in both lakes and the ocean – we synthesize progress in understanding nuances and caveats of δ30Si-based proxies in order to answer whether the fall-off in δ30Si-based Quaternary research is warranted. We suggest that with some simple steps that can be readily implemented, and with the closing of key knowledge gaps, there is no reason to believe silicon isotopes do not have a promising future in the Quaternary sciences.

The Analysis of NPP Changes under Different Climatic Zones and under Different Land Use Types in Henan Province, 2001–2020

Net Primary Productivity (NPP) is a crucial indicator of ecological environment quality. To better understand the carbon absorption and carbon cycling capabilities of Henan Province, this study investigates the trends and driving factors of NPP across different climatic zones and land use types. The Theil–Sen Median trend analysis method and the Mann–Kendall trend test are employed to monitor NPP changes from 2001 to 2020. The average annual NPP in Henan Province during this period was 414.61 gC·m−2·year−1, showing a significant increasing trend with a growth rate of 3.73 gC·m−2·year−1. Spatially, both the annual average NPP and its increase rate were higher in the western part of Henan compared to the eastern part, and NPP variability was more stable in the southern region than in the northern region. By classifying climatic zones and using the Geodetector method to assess NPP sensitivity to natural factors, the results show that climate and vegetation factors jointly influence NPP variations, with annual precipitation being the primary natural factor affecting NPP trends in Henan Province from 2001 to 2020. By analyzing the NPP gain and loss matrix, the impact of land use changes on NPP was evaluated. Forests had the highest average annual NPP at 483.52 gC·m−2·year−1, and the conversion of arable land to urban areas was identified as the primary land change type leading to NPP reductions. In the subtropical zone of Henan, forests, croplands, and grasslands exhibited higher NPP values and increase rates compared to those in the warm belt. This study provides new insights into the spatial variation of NPP caused by changes in climatic zones and land use types.

Exploring Prostate Cancer Incidence Trends and Age Change in Cancer Registration Areas of Jiangsu Province, China, 2009 to 2019

(1) Background: Over the past few decades, Jiangsu Province, China, has witnessed a remarkable surge in the incidence of prostate cancer (PCa), accompanied by notable demographic shifts; (2) Methods: PCa data for Jiangsu Province from 2009 to 2019 were obtained from the Jiangsu Cancer Registry. We calculated crude and age-specific incidence rates (ASIRs), average age at onset, and age-specific composition ratios. Standardization was performed based on the Segi’s world population. Birth cohorts (1929–2019) were analyzed to assess PCa incidence by birth year. Trend analysis was conducted using the Joinpoint Regression Model, and average annual percent changes (AAPCs) with corresponding 95% confidence interval (CI) were computed. A linear regression model was used to analyze the relationship between the average age at diagnosis and calendar years; (3) Results: The ASIRs of PCa in Jiangsu Province increased significantly, with an AAPC of 11.25% (95%CI: 10.09%, 12.42%) from 2009 to 2019. This increase was observed across all age groups, particularly among those aged 0–59 years. Birth cohort analysis revealed a rising trend with earlier birth years showing higher incidence, notably in the 1959 cohort. In rural areas, the age-standardized average age at onset of PCa decreased from 75.45 years in 2009 to 73.39 years in 2019, and the peak age group shifted from 75–79 years in 2009 to 70–74 years in 2019; (4) Conclusions: The rising incidence of PCa in Jiangsu Province, along with an increased proportion of cases in younger age groups, highlights the need for targeted interventions.

Analysis of Research Hot Spots in Chinese and International English Ecohydrological Literature

ABSTRACTTo enhance comprehension of current research progress in the field of ecohydrology and to provide valuable references for future related research, policy formulation and international collaboration, this article relies on ecohydrology‐related literature and citation records in four databases: China Knowledge Network (CNKI), Wanfang Database, Web of Science (WOS) and Elsevier, up until the end of 2022. We use publication and citation trends analysis along with keyword hotspot analysis using VOS viewer to investigate publication and citation trends in Chinese and English literature. The study systematically analyse the process of keyword changes and research hotspots in Chinese and international English literature, providing a detailed explanation of the differences in research hotspots and the reasons for their formation. The research indicates that since the inception of the term ‘ecohydrology’, relevant literature has displayed sluggish growth alongside rapid development. Additionally, alterations in primary keywords have differed between Chinese and English literature over time. However, ‘groundwater’ has consistently retained a significant amount of attention within Chinese literature. Groundwater has been extensively studied in Chinese literature, with a particular focus on eco‐hydrological processes, their effects, modelling and techniques. Similarly, English language literature is abundant with keywords denoting pivotal concepts like the environment, hydrology, fauna and rivers. These areas have been the focal points of research for international scholars. Regional characteristics, ecological conditions, economic development level and scientific research priorities, among other factors, are all significant contributors to the development of the field of ecohydrology. Differences in research hotspots can also be attributed to geographical characteristics, ecological environment conditions and scientific research priorities. Over the past decade, there has been a gradual convergence in research between Chinese and English literature. The current hotspots of research in ecohydrology include basic research, theoretical applications and adaptive wide‐area mechanistic research. In the future, the discipline of ecohydrology is likely to face numerous challenges and opportunities related to climate change, resource management, and societal needs. Interdisciplinary collaboration, technological innovation and global cooperation will continue to drive breakthroughs in ecohydrology research.

Global, regional, and national burdens of acne vulgaris in adolescents and young adults aged 10-24 years from 1990 to 2021: a trend analysis.

Acne vulgaris is a common skin condition affecting adolescents and young adults worldwide, yet data on its burden and trends remain limited. We aimed to investigate trends in the burden of acne vulgaris among adolescents and young adults aged 10-24 years at global, regional, and national levels. We retrieved data from the Global Burden of Disease Study (GBD) 2021 for individuals aged 10-24 years in 204 countries and territories from 1990 to 2021. We analyzed the numbers, age-standardised rates, and average annual percentage changes (AAPCs) of the prevalence, incidence, and disability-adjusted life-years (DALYs) for acne vulgaris at the global, regional, and national levels. Additionally, we examined these global trends by age, gender, and Socio-demographic Index (SDI). Globally, the age-standardised prevalence rate of acne vulgaris among adolescents and young adults increased from 8,563.4 per 100,000 population (95% UI 7,343.5-9,920.1) in 1990 to 9,790.5 (95% UI 8,420.9-11,287.2) per 100,000 population in 2021, with an AAPC of 0.43 (95% CI 0.41-0.46). The age-standardised incidence rate and age-standardised DALY rate also showed a similar upward trend. Regionally, Western Europe had the highest age-standardised prevalence, incidence, and DALY rates, while North Africa and the Middle East had the largest increase in these rates. By SDI quintile, the high SDI region had the highest age-standardised prevalence, incidence, and DALY rates from 1990 to 2021, whereas the low-middle SDI region had the lowest burden of acne vulgaris but experienced the most significant increase in these rates. Globally, the age-standardised prevalence rate of acne vulgaris in 2021 was approximately 25% higher in females than in males (10,911.8 per 100,000 population vs. 8,727.8 per 100,000 population). Among all age groups, adolescents aged 15-19 years had the highest age-specific prevalence rate, while adolescents aged 10-14 years experienced the largest increase from 1990 to 2021 (AAPC = 0.50, 95% CI 0.48-0.52). The burden of acne vulgaris among adolescents and young adults has continued to increase in nearly all countries since the 1990s. Managing this condition remains a significant challenge, necessitating more effective and targeted interventions to control the acne burden.

Economic Analysis of the Export Trends of Livestock and Livestock Products in India

Livestock provides livelihood to two-third of rural masses and employs about 8.8 per cent population of India. While dairying ensures livelihood to 70 million farm families. The study utilized export data from government sources and conducted a statistical analysis to assess trends and stability. Data revealed that the overall export value increased significantly from ₹22,092.62 crore in 2011-12 to ₹48,947.55 crore in 2021-22, reflecting a compound annual growth rate (CAGR) of 4.90%. Buffalo meat emerged as the leading export product, while dairy products exhibited a notable growth rate while dairy products and other categories showed varied growth.
