By selecting stable and detectable drug prototypes or metabolites in sewage samples, near real-time detection of disease conditions can be achieved. This study selected oseltamivir carboxylate, the primary metabolite of first-line antiviral oseltamivir, as a biomarker. Based on the concentration of oseltamivir carboxylate in wastewater, the consumption and usage rate of oseltamivir were calculated by reverse engineering. Quarterly sampling was conducted at 46 urban sewage treatment plants in representative 5 cities in the middle and lower reaches of the Yangtze River, from November 2022 to December 2023. The concentration range of oseltamivir acid in sewage samples is 1.270−1 279 ng/L, the daily mass load of oseltamivir per 1 000 inhabitants in the surveyed cities ranged from 9.560 to 544.7 mg/d, and the average utilization rate is 0.06‰−3.63‰. The research results indicate that in March 2023, Wuxi City experienced a spring influenza peak, while Bengbu, Tongling, Suzhou, and Changzhou City experienced a small summer influenza peak in May. In November and December 2023, Wuxi, Changzhou, and Bengbu City experienced a winter influenza peak, the results are consistent with the official statistics of the National Center for Disease Control and Prevention and the National Influenza Center, which reflect the influenza epidemic situation in southern cities. The integration of this methodology with clinical diagnostic rates could provide near real-time data support for future influenza prevention and control strategies.

Objective This study aimed to explore the spatial heterogeneity and risk factors for dental caries in 12-year-old children in Shanxi province,China. Methods The data encompassed 3,721 participants from the two most recent oral health surveys conducted across 16 districts in Shanxi Province in 2015 and 2018.Eighteen specific variables were analyzed to examine the interplay between socioeconomic factors,medical resources and environmental conditions.The Geo-detector model was employed to assess the impacts and interactions of these ecological factors. Results Socioeconomic factors(Q=0.30,P<0.05)exhibited a more substantial impact compared to environmental(Q=0.19,P<0.05)and medical resource factors(Q=0.25,P<0.05).Notably,the urban population percentage(UPP)demonstrated the most significant explanatory power for the spatial heterogeneity in caries prevalence,as denoted by its highest q-value(q=0.51,P<0.05).Additionally,the spatial distribution's heterogeneity of caries was significantly affected by SO2 concentration(q=0.39,P<0.05)and water fluoride levels(q=0.27,P<0.05)among environmental factors. Conclusion The prevalence of caries exhibited spatial heterogeneity,escalating from North to South in Shanxi Province,China,influenced by socioeconomic factors,medical resources,and environmental conditions to varying extents.

Endodontic diseases are a kind of chronic infectious oral disease.Common endodontic treatment concepts are based on the removal of inflamed or necrotic pulp tissue and the replacement by gutta-percha.However,it is very essential for endodontic treatment to debride the root canal system and prevent the root canal system from bacterial reinfection after root canal therapy(RCT).Recent research,encompassing bacterial etiology and advanced imaging techniques,contributes to our understanding of the root canal system's anatomy intricacies and the technique sensitivity of RCT.Success in RCT hinges on factors like patients,infection severity,root canal anatomy,and treatment techniques.Therefore,improving disease management is a key issue to combat endodontic diseases and cure periapical lesions.The clinical difficulty assessment system of RCT is established based on patient conditions,tooth conditions,root canal configuration,and root canal needing retreatment,and emphasizes pre-treatment risk assessment for optimal outcomes.The findings suggest that the presence of risk factors may correlate with the challenge of achieving the high standard required for RCT.These insights contribute not only to improve education but also aid practitioners in treatment planning and referral decision-making within the field of endodontics.

Objective:To explore the influencing factors for poor prognosis in patients with severe traumatic brain injury (TBI).Methods:A retrospective analysis was performed; the clinical data of 389 patients with severe TBI admitted to Department of Neurosurgery, 900 th Hospital of PLA Joint Logistics Team from January 2018 to December 2022 were collected. Glasgow Outcome Scale (GOS) was used to evaluate the prognoses 6 months after discharge. Differences in clinical data between the good prognosis group (GOS scores of 4-5) and poor prognosis group (GOS scores of 1-3) were compared. Multivariate Logistic regression was used to analyze the independent influencing factors for poor prognosis in severe TBI patients, and receiver operating characteristic (ROC) curve was used to analyze the predictive value of the regression model in severe TBI patients. Results:At 6 months after discharge, 182 patients (46.8%) had favorable prognosis and 207 patients (53.2%) had unfavorable prognosis. Compared with the good prognosis group, the poor prognosis group had significantly older age, lower Glasgow Coma Scale (GCS) scores, higher proportions of patients with subdural hematoma (SDH), cerebral hernia, cerebral infarction and encephalocele, higher blood glucose, lower albumin, lower K +, Ca 2+ and CO 2, higher international normalized ratio (INR) and C-reactive protein (CRP), lower lymphocyte/monocyte ratio (LMR), and higher neutrophil/lymphocyte ratio (NLR) and systemic immunoinflammatory index (SII, P<0.05). Multivariate Logistic regression analysis showed that age ( OR=1.045, 95% CI: 1.025-1.066, P<0.001), GCS score ( OR=0.487, 95% CI: 0.388-0.612, P<0.001), cerebral hernia ( OR=3.471, 95% CI: 1.604-7.511, P=0.002), blood glucose ( OR=1.109, 95% CI: 1.010-1.218, P=0.030), INR ( OR=8.073, 95% CI: 1.199-54.354, P=0.032) and high SII ( OR=8.311, 95% CI: 4.089-16.892, P<0.001) were independent influencing factors for poor prognosis in severe TBI patients. ROC curve showed that area under the curve of the regression model predicting poor prognosis in severe TBI patients was 0.935 (95% CI: 0.905-0.957, P<0.001), enjoying sensitivity of 88.89% and specificity of 85.16%. Conclusion:Severe TBI patients with advanced age, low GCS score, high INR and SII, elevated blood glucose, or cerebral hernia have poor prognosis.

Objectives: This study aimed to present the Asia-Pacific consensus on long-term and sequential therapy for osteoporosis, offering evidence-based recommendations for the effective management of this chronic condition.The primary focus is on achieving optimal fracture prevention through a comprehensive, individualized approach. Methods: A panel of experts convened to develop consensus statements by synthesizing the current literature and leveraging clinical expertise. The review encompassed long-term anti-osteoporosis medication goals, first-line treatments for individuals at very high fracture risk, and the strategic integration of anabolic and anti resorptive agents in sequential therapy approaches. Results: The panelists reached a consensus on 12 statements. Key recommendations included advocating for anabolic agents as the first-line treatment for individuals at very high fracture risk and transitioning to anti resorptive agents following the completion of anabolic therapy. Anabolic therapy remains an option for in dividuals experiencing new fractures or persistent high fracture risk despite antiresorptive treatment. In cases of inadequate response, the consensus recommended considering a switch to more potent medications. The consensus also addressed the management of medication-related complications, proposing alternatives instead of discontinuation of treatment. Conclusions This consensus provides a comprehensive, cost-effective strategy for fracture prevention with an emphasis on shared decision-making and the incorporation of country-specific case management systems, such as fracture liaison services. It serves as a valuable guide for healthcare professionals in the Asia-Pacific region, contributing to the ongoing evolution of osteoporosis management.

Interleukin-1 receptor associated kinase 4 (IRAK-4), acting as a serine threonine kinase, is considered as a key signal node for the transduction of IL-1R family and TLRs signal pathway. Studies have found that IRAK-4 has a hand in many signal pathways, involving the inflammatory response of human joints, intestines, liver and nervous system, as well as other autoimmune diseases. It is also one of the causes of drug resistance of some cancer cells. Therefore, IRAK-4 tends to be an effective therapeutic target for inflammatory diseases and cancer. The prospects for the development of drugs in this pathway is to develop novel IRAK-4 small molecule inhibitors and investigate their safety and effectiveness, enrich the clinical treatment of inflammatory and cancer diseases finally. This paper classified and summarized the latest research progress on small molecule inhibitors of IRAK-4 signaling pathway according to structures of the compounds, in order to provide assistances and references for the research and development of related drugs.

Objective:To study the role of myocardial work parameters in early identification of myocardial injury in neonatal asphyxia.Methods:From July 2020 to December 2021, neonates diagnosed with mild neonatal asphyxia admitted to the Department of Neonatology of our hospital within 24 h after birth were prospectively enrolled into the asphyxia group. Neonates without asphyxia during the same period were selected as the control group and matched with the asphyxia group for gender, gestational age and birth weight at a ratio of 1:1~1:2. The asphyxia group was subgrouped into preterm asphyxia group and term asphyxia group. All neonates received echocardiography within 24 h after birth. Multiple parameters were measured including M-mode, two-dimensional image, Doppler image, global longitudinal strain (GLS) and myocardial work parameters [global work index (GWI), global constructive work (GCW), global wasted work (GWW), global work efficiency (GWE)]. The level of serum N-terminal pro brain natriuretic peptide (NT-proBNP) was recorded in the asphyxia group. The data were compared between the asphyxia group and the control group. Correlations between myocardial work parameters and other parameters were analyzed.Results:A total of 33 cases were in the asphyxia group and 43 cases were in the control group. The preterm asphyxia group (18 cases) showed significantly lower GWI and GCW than the preterm control group (18 cases) [GWI: (702±153) mmHg vs. (879±205) mmHg, GCW: (1 016±221) mmHg vs. (1 200±271) mmHg] ( P<0.05). No differences existed in GLS, GWW and GWE. The term asphyxia group (15 cases) showed significantly lower GWW than the term control group (25 cases) [45.0 (30.0, 65.0) mmHg vs. 71.0 (35.5,85.5) mmHg] ( P<0.05). No differences existed in GLS, GWI, GCW and GWE. GWI was negatively correlated with serum NT-proBNP level ( r=-0.327, P<0.05). Conclusions:GWI and GCW may indicate myocardial injury in preterm neonates with mild asphyxia.

Bone defects caused by different causes such as trauma, severe bone infection and other factors are common in clinic and difficult to treat. Usually, bone substitutes are required for repair. Current bone grafting materials used clinically include autologous bones, allogeneic bones, xenografts, and synthetic materials, etc. Other than autologous bones, the major hurdles of rest bone grafts have various degrees of poor biological activity and lack of active ingredients to provide osteogenic impetus. Bone marrow contains various components such as stem cells and bioactive factors, which are contributive to osteogenesis. In response, the technique of bone marrow enrichment, based on the efficient utilization of components within bone marrow, has been risen, aiming to extract osteogenic cells and factors from bone marrow of patients and incorporate them into 3D scaffolds for fabricating bone grafts with high osteoinductivity. However, the scientific guidance and application specification are lacked with regard to the clinical scope, approach, safety and effectiveness. In this context, under the organization of Chinese Orthopedic Association, the Expert consensus for the clinical application of autologous bone marrow enrichment technique for bone repair ( version 2023) is formulated based on the evidence-based medicine. The consensus covers the topics of the characteristics, range of application, safety and application notes of the technique of autologous bone marrow enrichment and proposes corresponding recommendations, hoping to provide better guidance for clinical practice of the technique.

Periarticular fracture of the shoulder is a common type of fractures in the elderly. Postoperative adverse events such as internal fixation failure, humeral head ischemic necrosis and upper limb dysfunction occur frequently, which seriously endangers the exercise and health of the elderly. Compared with the fracture with normal bone mass, the osteoporotic periarticular fracture of the shoulder is complicated with slow healing and poor rehabilitation, so the clinical management becomes more difficult. At present, there is no targeted guideline or consensus for this type of fracture in China. In such context, experts from Youth Osteoporosis Group of Chinese Orthopedic Association, Orthopedic Expert Committee of Geriatrics Branch of Chinese Association of Gerontology and Geriatrics, Osteoporosis Group of Youth Committee of Chinese Association of Orthopedic Surgeons and Osteoporosis Committee of Shanghai Association of Chinese Integrative Medicine developed the Chinese expert consensus on the diagnosis and treatment of osteoporotic periarticular fracture of the shoulder in the elderly ( version 2023). Nine recommendations were put forward from the aspects of diagnosis, treatment strategies and rehabilitation of osteoporotic periarticular fracture of the shoulder, hoping to promote the standardized, systematic and personalized diagnosis and treatment concept and improve functional outcomes and quality of life in elderly patients with osteoporotic periarticular fracture of the shoulder.
