Global burden of disease for musculoskeletal disorders in all age groups, from 2024 to 2050, and a bibliometric-based survey of the status of research in geriatrics, geriatric orthopedics, and geriatric orthopedic diseases

BACKGROUND

Orthopaedic diseases in the elderly pose a significant disease burden, and the number of research papers on the subject is increasing every year.

METHODS

The GBD database was used to analyze the global disease burden of musculoskeletal disorders in all age groups from 2024 to 2050. The source for bibliometrics was the WoSCC SCI-E database.

RESULTS

Global disability-adjusted life years (DALYs) for musculoskeletal disorders by age were dominated by those aged 70 years and older, but the rate of change in DALYs between 2024 and 2050 was approximately ± 1%. We performed a descriptive analysis of 164,521 geriatrics articles, and 7155 geriatric orthopedics and geriatric orthopedic articles, and performed clustering, co-citation, collaborative network, and burst citation analyses based on Citespace and VOSviewer. Seven clustering tags containing hot content and 26 burst citation keywords containing hot content were finally targeted.

CONCLUSION

DALY in older adults over 70 years of age accounts for a significant portion of the disease burden of musculoskeletal disorders. Possible future research hotspots in geriatric orthopedics and geriatric bone diseases include three directions: (1) novel clinical procedures and postoperative management (2) various comorbidities caused by SARS-CoV-2 infections and other pathogens; and (3) effectiveness of Stem Cell Therapy in Clinical Applications and Biological Mechanisms of Stem Cell Therapy.

Analysis of research status and trends on nano-agricultural application: a bibliometric study

Introduction

The rapid global population growth and limitations of traditional agricultural practices have resulted in inadequate nutrient supply. Nano-agricultural technology presents significant potential for enhancing crop growth and resistance, reducing stresses, and providing economic benefits with lower environmental risks.

Methods

In this study, a bibliometric analysis of nano-agricultural applications was conducted using the Web of Science Core Collection, and 2,626 publications from 2000 to 2023 were identified, with an exponential increase in both publications and citations.

Results and discussion

European and Asian countries and institutions are more actively involved, although USA produces the highest-quality papers. Additionally, this field has evolved through two stages: the first stage (2000-2016) focused on the toxicology of nanomaterials (NMs), while the second stage (2017-present) emphasizes NMs as nanofertilizers to promote crop growth, and as nanoregulators or nanopesticides to enhance crop resistance against biotic stress and abiotic stress. Finally, future research perspectives were also proposed, including the optimalizations of NMs, the investigations of the behavior and bioavailability of NMs driven by rhizosphere and phyllosphere process, interdisciplinary collaboration across various fields, the application of NMs from laboratory to the field, and the long-term environmental behaviors and assessments of NMs in diverse ecosystems. Overall, this bibliometric study provides a valuable reference for understanding the development of this field and pinpointing research frontiers.

Acclimatization of a sequencing batch vertical oxidation pond with simulated agricultural wastewater using duckweed as vegetation: analysis of efficiency, Biomass, and Soil properties

Vertical oxidation pond operated in sequencing batch mode (HRT: 1.25 day) with duckweed as the vegetation was used to acclimatize with simulated agricultural wastewater. The maximum removal rate of urea [371 g/(m3.d)] and COD [222.4 g/(m3.d)] were observed at moderate concentrations of urea (500 mg/L), N-P-K (60 mg/L), and pesticide (20 mg/L). Inhibition and toxicity posed by higher concentrations, decreased the removals of urea (83% to 61%), COD (81% to 51%), and TDS (76% to 50%) at the end of the acclimatization. Steady removal (> 99%) of PO43--P was observed during acclimatization. Effluent pH increased due to the generation of NH4+-N (maximum 370 ± 5 mg/L) from the assimilation of urea. Oxidation of ammonia led to the maximum generation of NO2--N and NO3--N of 10 mg/L and 9 mg/L, respectively. Particles less than 300 μm increased, and both specific gravity (from 2.62 to 2.42) and maximum dry density (from 1.73 to 1.30 g/cm3) of the base soil decreased with an increase in urea, N-P-K, and pesticide. Reactor biomass increased (1.42 to 1.90 g/L) up to initial concentrations of urea (500 mg/L), N-P-K (60 mg/L), and pesticide (20 mg/L), then decreased (1.68 g/L) with an increase in concentration.

Immersive Experience and Climate Change Monitoring in Digital Landscapes: Evidence from Somatosensory Sense and Comfort

In this study, the virtual engine software (Unity 2019, Unity Software Inc., San Francisco, California, the U.S.) was used to generate a digital landscape model, forming a virtual immersive environment. Through field investigation and emotional preference experiments, the ancient tree ecological area and the sunlight-exposed area were respectively monitored, and the somatosensory comfort evaluation model was established. The subjects showed the highest degree of interest in the ancient tree ecological area after landscape roaming experience, and the mean variance in SC fluctuation was 13.23% in experiments. The subjects were in a low arousal state and had a significant degree of interest in the digital landscape roaming scene, and there was a significant correlation between positive emotion, somatosensory comfort and the Rating of Perceived Exertion index; moreover, the somatosensory comfort of the ancient tree ecological area was higher than that of the sunlight-exposed area. Meanwhile, it was found that somatosensory comfort level can effectively distinguish the comfort level between the ancient tree ecological area and the sunlight-exposed area, which provides an important basis for monitoring extreme heat. This study concludes that, in terms of the goal of harmonious coexistence between human and nature, the evaluation model of somatosensory comfort can contribute to reducing people's adverse views on extreme weather conditions.

Low-carbon economy and policy implications: a systematic review and bibliometric analysis

In the face of the rapid increase of carbon emissions, climate warming, and an epidemic situation, low-carbon economy is attracting growing attention. Using bibliometric analysis and machine learning methods, the paper conducts a systematic review in the low-carbon economy. Using the Web of Science Core Collection database, 1433 articles from 1990 to 2021 were selected for review. We find that the trajectories of the low-carbon economy research can be divided into four phases: exploration, fermentation, rising, and flourishing. The low-carbon economy research can be categorized into five clusters: low-carbon energy policy, carbon footprint and carbon trading, energy-economy-environment system, energy efficiency and its decomposition, and carbon emission drivers. The findings of this review study shed light on the role and effects of low-carbon economic policies on energy futures.

Bibliometric Analysis of the Toxicity of Bisphenol A

Bisphenol A (BPA) is used worldwide and research on the toxicity of BPA has advanced rapidly in the last few decades. This study aimed to evaluate the global scientific output of toxicity of BPA and explore the hot spots and research trends. All available articles related to the toxicity of BPA until 2022 were retrieved from the Web of Science Core Collection database. The VOSviewer, a bibliometric analysis software, was used to analyze the information of included articles, including countries/institutions, international cooperation, journals, citations, and keywords. Among 1644 retrieved articles, 1611 eligible studies were identified for analysis, and the annual publications increased with time in the past three decades. China and the United States were the most active contributors in this field. Chinese Academy of Sciences and the Dow chemical company conducted relatively more research than others about BPA toxicity. The journal “Chemosphere” published the most studies on “BPA toxicity”. Before 2015, most research focused on estrogenic activity and the test system mainly utilized animal experiments. However, in recent years, research related to toxic mechanisms of BPA at the cellular level and the toxicity of its analogs have received widespread attention. Considering some critical research gaps, future research on BPA toxicology should probably focus on the molecular biology of toxic mechanism, mixture toxicity, and co-exposure of BPA substitutes. This study will help researchers understand past and current research trends, hot spots, and trends of toxicity studies of BPA and, thus, contribute to further research and risk management of BPA.
