ObjectiveTo evaluate the antitumor activity of Periplaneta americana extract(PAE) against human-derived lung adenocarcinoma organoids(LUAD-PDOs) and to elucidate its potential mechanism based on transcriptomics. MethodsFresh tumor and adjacent normal tissues from patients with LUAD were collected to construct LUAD-PDOs and normal lung organoid(Nor-PDOs) models using 3D organoid culture technology. The effective intervention concentration of PAE was determined using the cell counting kit-8(CCK-8) assay. Experimental groups included the model group(LUAD-PDOs), normal group, model administration group(LUAD-PDOs+PAE), and normal administration group(Nor-PDOs+PAE). Hematoxylin-eosin(HE) staining was used to observe the pathological structures of PDOs, immunohistochemistry(IHC) was performed to detect the expressions of the proliferation marker Ki-67 and lung adenocarcinoma differentiation markers cytokeratin-7(CK-7) and Napsin A, TUNEL staining was applied to detect cell apoptosis. RNA sequencing(RNA-Seq) was conducted to identify differentially expressed genes(DEGs), followed by Gene Ontology(GO), Kyoto Encyclopedia of Genes and Genomes(KEGG), and Gene Set Enrichment Analysis(GSEA), alongside protein-protein interaction(PPI) network analysis to screen core mechanisms. Finally, key targets were validated by integrating external database analysis with immunofluorescence(IF). ResultsNor-PDOs and LUAD-PDOs that highly recapitulated the pathological characteristics of the primary tissues were successfully established. The CCK-8 assay determined that the effective intervention concentration of PAE was 16 g·L-1. Morphological observation showed that Nor-PDOs exhibited lumen-forming structures, whereas LUAD-PDOs displayed dense, solid structures. CCK-8 and TUNEL assays revealed that, compared with the model group, PAE intervention inhibited the proliferation of LUAD-PDOs and promoted apoptosis in LUAD cells, while showing no significant effect on the viability of Nor-PDOs. Transcriptomic analysis identified 719 DEGs that were significantly reversed after PAE intervention(347 up-regulated and 372 down-regulated)(P<0.05). GO enrichment analysis indicated that DEGs in the model administration group were significantly enriched in biological processes related to cell cycle regulation compared to the model group. KEGG pathway analysis revealed that PAE affected pathways related to proliferation and metabolism, including pathways in cancer and the p53 signaling pathway. GSEA further confirmed that PAE significantly enhanced the activity of the p53 signaling pathway(P<0.05). PPI network analysis indicated that breast cancer type 1 susceptibility protein(BRCA1) and checkpoint kinase 1(CHEK1) were the core down-regulated targets in the p53 pathway. IF verified the high expression of BRCA1 and CHEK1 in LUAD-PDOs and their significant downregulation after PAE intervention(P<0.05). Furthermore, survival analysis based on The Cancer Genome Atlas(TCGA) database indicated that low expression of BRCA1 and CHEK1 was significantly associated with prolonged overall survival in patients with LUAD(P<0.05). ConclusionPAE effectively inhibits proliferation of LUAD-PDOs and promotes their apoptosis, its anti-tumor mechanism is potentially associated with the activation of the p53 signaling pathway, with BRCA1 and CHEK1 genes likely serving as key downstream targets for the effects of PAE.

Osteoarthritis (OA), a highly prevalent degenerative joint disease worldwide, is defined by articular cartilage degradation, abnormal bone remodeling, and persistent chronic inflammation. It severely compromises patients’ quality of life, and currently, there is no radical cure. Abnormal mechanical stress is widely regarded as a core driver of OA pathogenesis, and the exploration of mechanical signal perception and transduction mechanisms has become crucial for deciphering OA’s pathophysiological processes. Piezo1, a key mechanosensitive cation channel belonging to the Piezo protein family, has recently gained significant attention due to its pivotal role in mediating cellular responses to mechanical stimuli in joint tissues. This review systematically examines Piezo1’s expression patterns, regulatory mechanisms, and pathological functions in OA, with a particular focus on its dual roles in modulating chondrocyte homeostasis and bone metabolism disorders, while also delving into the underlying molecular signaling pathways and potential therapeutic implications. Piezo1, consisting of approximately 2 500 amino acids and forming a unique trimeric propeller-like structure, is widely expressed in chondrocytes, osteocytes, mesenchymal stem cells, and synovial cells. It exhibits permeability to cations such as Ca2+, K+, and Na+, and directly responds to membrane tension changes induced by mechanical stimuli like fluid shear stress and mechanical overload. In OA patients and animal models, Piezo1 expression is significantly upregulated, especially in cartilage regions subjected to abnormal mechanical stress (e.g., human temporomandibular joint cartilage). This overexpression is closely associated with aggravated cartilage degeneration, increased chondrocyte apoptosis, accelerated cellular senescence, and intensified inflammatory responses. Mechanical overload and pro-inflammatory cytokines (e.g., IL-1β) are key inducers of Piezo1 upregulation: IL-1β activates the PI3K/AKT/mTOR signaling pathway to enhance Piezo1 expression, forming a pathogenic positive feedback loop that inhibits chondrocyte autophagy, promotes apoptosis, and further accelerates joint degeneration. Mechanistically, Piezo1 mediates OA progression through multiple interconnected pathways. When activated by mechanical stress, Piezo1 triggers excessive Ca2+ influx, leading to endoplasmic reticulum stress (ERS) and mitochondrial dysfunction, which directly induce chondrocyte apoptosis. This process involves the activation of downstream signaling cascades such as cGAS-STING and YAP-MMP13/ADAMTS5. YAP, a transcriptional regulator, upregulates the expression of matrix metalloproteinase 13 (MMP13) and aggrecanase (ADAMTS5), thereby accelerating cartilage matrix degradation. Additionally, Piezo1-driven Ca2+ overload promotes the accumulation of reactive oxygen species (ROS) and upregulates senescence markers (p16 and p21), accelerating chondrocyte senescence via the p38MAPK and NF-κB pathways. Senescent chondrocytes secrete senescence-associated secretory phenotype (SASP) factors (e.g., IL-6, IL-1β), further amplifying joint inflammation. In terms of bone metabolism, Piezo1 maintains joint homeostasis by promoting the differentiation of fibrocartilage stem cells into chondrocytes and balancing bone formation and resorption through regulating the FoxC1/YAP axis and RANKL/OPG ratio. Therapeutically, targeting Piezo1 shows promising potential. Preclinical studies have demonstrated that Piezo1 inhibitors (e.g., GsMTx4) can reduce joint damage and alleviate pain in OA mice. Simultaneously, siRNA-mediated co-silencing of Piezo1 and TRPV4 (another mechanosensitive channel) decreases intracellular Ca2+ concentration, inhibits chondrocyte apoptosis, and promotes cartilage repair. Conditional knockout of Piezo1 using Gdf5-Cre transgenic mice alleviates cartilage degeneration in post-traumatic OA models by downregulating MMP13 and ADAMTS5 expression. Despite existing challenges, such as off-target effects of inhibitors, inefficient local drug delivery, and interindividual genetic variability, strategies like developing selective Piezo1 antagonists, optimizing targeted nanocarriers, and combining Piezo1-targeted therapy with physical therapy provide viable avenues for clinical translation. The authors propose that Piezo1 serves as a critical therapeutic target for OA, and future research should focus on deciphering its context-dependent regulatory networks, developing tissue-specific intervention strategies, and validating their efficacy and safety in clinical trials to address the unmet medical needs of OA patients.

Objective To compare the clinical efficacy of neuroendoscope-assisted evacuation and navigation-assisted puncture drainage in treating thalamic hemorrhage breaking into the ventricle. Methods A retrospective analysis was conducted on the clinical data of 93 patients with thalamic hemorrhage breaking into the ventricle at Taihe Hospital of Wannan Medical College between January 2022 and February 2024. The patients received neuroendoscope-assisted removal of thalamic hematoma combined with contralateral extraventricular drainage (n=44, neuroendoscope group) and navigation-assisted thalamic hematoma puncture drainage combined with contralateral extraventricular drainage (n=49, navigation group), respectively. The treatment efficacy, surgical situation, and prognosis between the two groups were compared. Results The neuroendoscope group had longer operation duration, more intraoperative blood loss, higher hospitalization costs than the navigation group (P<0.05). The neuroendoscope group had higher hematoma clearance rate 3rd after surgery and shorter length of stay than the navigation group (P<0.05). There was no significant difference in the incidence of intracranial infection after surgery between the two groups. The neuroendoscope group had higher Glasgow coma scale (GCS) score at 1 week after surgery and Glasgow outcome scale (GOS) score at 3 months after surgery (P<0.01). Conclusions Compared with navigation-assisted puncture, neuroendoscope-assisted evacuation can improve the thalamic hemorrhage clearance rate, shorten the length of stay, and improve the prognosis of patients.

ObjectiveTo explore the mechanism of Sangpi Zhike prescription in treating cough after respiratory syncytial virus (RSV) infection through the "lung-intestine co-treatment" approach using network pharmacology and animal experimental validation. MethodsActive ingredients and targets of Sangpi Zhike prescription were retrieved from the Traditional Chinese Medicine Systems Pharmacology (TCMSP) database. Disease targets were obtained from GeneCards and Online Mendelian Inheritance in Man(OMIM) databases. Protein-protein interaction (PPI) networks and drug-component-target networks were constructed using overlapping targets between drugs and diseases to identify core targets. Gene ontology(GO) and Kyoto encyclopedia of genes and genomes(KEGG) pathway enrichment analyses were performed on the overlapping targets. Sixty mouse models were established: 10 as the normal group, and the remaining mice were infected with RSV via slow nasal drip of RSV suspension, with cough induced using capsaicin solution. After modeling, mice were divided into a model group, a Montelukast Sodium group (1 mg·kg-1·d-1), and low, medium, and high dose groups of Sangpi Zhike prescription (4.875,9.75,and 19.5 g·kg-1·d-1), with 10 mice per group. From day 14 after RSV infection, the normal and model groups received saline via gavage, while other groups received corresponding drug treatments once daily for 5 d. Hematoxylin-eosin(HE) staining was used to observe pathological changes in lung and intestinal tissue. The protein content of extracellular signal-regulated kinase 1/2 (ERK1/2) and phosphorylated (p)-ERK1/2 in the lung and colon tissue of mice was detected by Western blot. Real-time polymerase chain reaction(Real-time PCR) detected ERK1/2 mRNA expression in lung and intestinal tissue. Immunohistochemistry assessed p-MEK1/2, p-ERK1/2, p-c-Fos protein levels, and inflammatory cytokines interleukin(IL)-4 and (TNF)-α in lung and colon tissue. ResultsNetwork pharmacology identified 184 active ingredients and 684 targets in Sangpi Zhike prescription, with 1 344 RSV-related disease targets and 209 overlapping targets. Core targets included TNF, Fos, and Jun. KEGG enrichment revealed 179 pathways, primarily mitogen-activated protein kinase(MAPK), cancer, TNF, and IL-17 signaling pathways. Animal experiments showed that, compared to those of the normal group, the lung tissue sections of the model group showed typical inflammatory damage, infiltration of inflammatory cells, rupture of alveolar septa, extensive alveolar fusion, and disruption of tight junctions between single-layer columnar epithelial cells in the intestinal tissue. The values of p-ERK1/2 and ERK1/2 in lung and intestinal tissue were significantly increased (P<0.01), and the expression level of ERK1/2 mRNA was significantly elevated (P<0.01). The levels of ERK1/2, p-MEK1/2, p-ERK1/2, p-c-Fos, IL-4, and TNF-α along the ERK pathway were significantly increased (P<0.05, P<0.01). Compared to the model group, Sangpi Zhike prescription groups showed reduced lung and intestinal inflammation, decreased p-ERK1/2/ERK1/2 ratios (P<0.05,P<0.01), lower ERK1/2 mRNA levels, and downregulated ERK pathway proteins (P<0.05,P<0.01). ConclusionSangpi Zhike prescription alleviates cough and intestinal symptoms after RSV infection via the "lung-intestine co-treatment" mechanism by suppressing expression levels of ERK1/2, p-MEK1/2, p-ERK1/2, p-c-Fos, IL-4, and TNF-α on ERK pathway components, thereby mitigating lung and intestinal pathological damage.

ObjectiveTo systematically evaluate the application of narrative education in undergraduate nursing teaching, to understand the current application status of narrative education, and to provide a theoretical basis for the subsequent establishment of a sound narrative education system. MethodsA systematic search was conducted for studies published in Chinese and English databases on applying narrative education to undergraduate nursing teaching, with the search period ranging from database inception to February 23, 2025. Literature was screened, and relevant information was extracted. A rigorous quality evaluation was conducted on the included studies, and a descriptive analysis was performed on their content. ResultsA total of 20 papers were included, involving 3,180 research subjects, all of whom were undergraduate nursing students. The results of descriptive analysis showed that the teaching model of narrative education primarily encompassed reading narrative works, watching films and videos, performing narrative scenarios, and writing reflective journals. The course setting and content covered pre-teaching preparation and in-teaching implementation. The evaluation of teaching effectiveness included the evaluation of teachers’ teaching methods (student evaluation/self-evaluation) and the evaluation of students’ learning effectiveness (course grade evaluation/humanistic care scale/empathy scale assessment, and others). ConclusionNarrative education combines abstract concepts with concrete clinical situations, which not only enriches students’ learning experiences but also enhances their humanistic literacy. Meanwhile, it provides teachers with opportunities to develop their narrative teaching skills, which requires them to possess profound professional knowledge and employ narrative techniques to guide students in reflection and critical thinking, thereby improving teaching quality and learning outcomes. Future efforts should consistently deepen the connotation research of narrative education and build a systematic nursing education system.

ObjectiveTo evaluate the therapeutic effects of modified Banxia Xiexintang(MBXT) on polycystic ovary syndrome with insulin resistance(PCOS-IR) rats and reveal its potential mechanisms based on the integrated analysis of transcriptomics and metabolomics. MethodsFemale SD rats were selected, and a PCOS-IR model was established by intragastric administration of letrozole combined with a high-fat diet for 21 days. The modeled rats were randomly divided into the model group, MBXT low-, medium-, and high-dose groups(6.62, 13.23, 26.46 g·kg-1), and metformin group(0.158 g·kg-1), with a normal group set up separately. After 14 days of administration, the estrous cycle was observed, ovarian morphology was examined by hematoxylin-eosin(HE) staining, and the levels of testosterone(T), estradiol(E2), follicle-stimulating hormone(FSH), and luteinizing hormone(LH) in serum were detected by enzyme-linked immunosorbent assay(ELISA). Serum metabolites and ovarian tissue gene expression were detected using ultra-performance liquid chromatography-quadrupole-electrostatic orbitrap mass spectrometry(UPLC-Q-Orbitrap-MS) and RNA-Seq technology, respectively, followed by multi-omics integrated analysis. ResultsPharmacodynamic findings revealed that all MBXT dose groups could reversed abnormal estrous cycles in PCOS-IR rats, improve polycystic ovarian lesions, and normalize dysregulated serum hormone levels(T, LH, E2, FS, P<0.05, P<0.01). Metabolomic analysis revealed that compared with the model group, MBXT reversed 278 differential metabolites such as estrone and S-formylglutathione, mainly involving pathways such as steroid hormone biosynthesis, glutathione metabolism, and lipid peroxidation regulation. Transcriptomic analysis identified 434 differentially expressed genes, and enrichment analysis revealed that MBXT significantly regulated lipid peroxidation defense systems, including glutathione metabolism, peroxisome function, and fatty acid metabolism, thereby intervening in ferroptosis processes. It also engaged in inflammation-related pathways such as the chemokine signaling pathway. Integrated analysis revealed that both metabolomics and transcriptomics co-enriched metabolic pathways associated with ferroptosis and fatty acid metabolism. And key Hub genes[such as Ras-related C3 botulinum toxin substrate 2 gene(Rac2) and Fas ligand gene(Faslg)] showed significant correlations with differential metabolites. ConclusionMBXT can effectively ameliorate reproductive dysfunction and metabolic disorders in PCOS-IR rats. Its mechanism may be related to remodeling the immune-metabolism network, particularly by regulating MHC-mediated immune responses, inhibiting local ovarian ferroptosis, and enhancing steroid hormone synthesis pathways.

ObjectiveTo investigate the mechanism of modified Banxia Xiexintang(MBXT) in improving ovarian dysfunction in polycystic ovary syndrome with insulin resistance(PCOS-IR) rats by inhibiting ferroptosis through the adenosine monophosphate(AMP)-activated protein kinase(AMPK)/fatty acid synthase(FASN)/glutathione peroxidase 4(GPX4) signaling pathway. MethodsSeventy-six female SD rats were randomly divided into a normal group(n=13) and a modeling group(n=63). The modeling group established a PCOS-IR model by intragastric administration of letrozole combined with a high-fat diet for 21 days. After successful modeling, these rats were randomly divided into the model group, MBXT low-, medium-, and high-dose groups(6.62, 13.23, 26.46 g·kg-1), metformin group(0.158 g·kg-1), and high-dose of MBXT combined with ferroptosis inducer Erastin group(15 mg·kg-1), with 10 rats in each group. After 14 days of intervention, ovarian pathological morphology was observed by hematoxylin-eosin(HE) staining, the mitochondrial ultrastructure of granulosa cells was observed by transmission electron microscopy(TEM), ovarian reactive oxygen species(ROS) levels were detected by dihydroethidium(DHE) probe, biochemical methods were used to detect Fe2+, malondialdehyde(MDA), glutathione(GSH) and other indicators in ovarian tissues, serum sex hormone and insulin levels were measured by enzyme-linked immunosorbent assay(ELISA), and the protein expressions of AMPK, FASN, acyl-CoA synthetase long-chain family member 4(ACSL4), GPX4, and solute carrier family 7 member 11(SLC7A11) in ovarian tissues were detected by Western blot. ResultsCompared with the normal group, the model group showed polycystic changes in the ovaries, with atrophy of mitochondria in granulosa cells and increased membrane density. Serum levels of testosterone(T), luteinizing hormone(LH), and insulin were significantly increased(P<0.01). The levels of ROS, MDA, 4-hydroxynonenal(4-HNE), and Fe2+ in ovarian tissues were significantly elevated(P<0.01), while adenosine triphosphate(ATP), GSH, and reduced nicotinamide adenine dinucleotide phosphate (NADPH) levels were significantly decreased(P<0.01). The phosphorylation levels of AMPK and acetyl-CoA carboxylase (ACC), as well as the protein expressions of SLC7A11, GPX4, and ferroptosis suppressor protein 1(FSP1) were significantly downregulated(P<0.01), whereas the expressions of FASN, ACSL4, and nuclear receptor coactivator 4(NCOA4) were significantly upregulated(P<0.01). Compared with the model group, MBXT intervention at various doses improved the above pathological changes and biochemical indicators in a dose-dependent manner, with the high-dose group showing the most significant effect(P<0.01). Compared with the MBXT high-dose group, the high-dose of MBXT combined with ferroptosis inducer Erastin group restored ovarian ferroptosis characteristics in rats, with increased ROS and lipid peroxidation products, and altered expressions of key proteins(P<0.05, P<0.01). ConclusionMBXT can effectively improve ovarian function and metabolic disorders in PCOS-IR rats. Its mechanism may be related to activating the AMPK/ACC signaling pathway, downregulating FASN and ACSL4 to reduce lipid peroxidation substrates, and restoring glucose-6-phosphate dehydrogenase/phosphoglycerate dehydrogenase(G6PD/PHGDH) metabolic flux to enhance the GPX4/FSP1 antioxidant defense system, thereby inhibiting ferroptosis in ovarian granulosa cells.

Esophageal cancer is a prevalent malignant tumor of the digestive tract in China, and radical surgery remains the cornerstone of its comprehensive treatment. However, multifactorial challenges such as postoperative gastrointestinal tract reconstruction, traumatic stress, and tumor-related metabolic disturbances render esophageal cancer patients highly susceptible to malnutrition. Perioperative nutritional support therapy plays a crucial role in enhancing surgical safety, improving clinical outcomes, and elevating patients' quality of life by regulating metabolic homeostasis, preserving organ function, and optimizing the immune microenvironment. This article reviews the mechanisms underlying malnutrition in esophageal cancer, methods for nutritional status assessment, and precision intervention pathways based on multi-omics evaluations. The aim is to strengthen clinicians' awareness of standardized perioperative nutritional management for esophageal cancer patients and promote its clinical implementation, thereby facilitating postoperative recovery and improving long-term quality of life.

Chinese Journal of School Health 2026;47(3):408-412
Objective:
To characterize longitudinal trajectories of testicular development in boys and breast development in girls, so as to provide reference data for understanding patterns of pubertal sexual maturation.
Methods:
Based on the Shanghai Pudong New Area Cohort Study on Growth, Development and Health in Children and Adolescents, a baseline survey was conducted in 2020 using a mult stage cluster random sampling method. A total of 2 184 children who completed all follow ups during the primary school period from 13 elementary schools in Pudong New Area,Shanghai,with annual follow ups during 2021-2025. Testicular volume and Tanner stage of breast development were assessed by professional physicians using standardized visual inspection and palpation. The age distribution of testicular volume and breast development was fitted by using cumulative link mixed models and Turnbull s nonparametric maximum likelihood estimation method.
Results:
Median ages for testicular volumes of 2, 3, 4 and 5 mL in boys were 7.07, 9.24, 10.29, and 11.57 years old, respectively. Median ages for Tanner breast stages Ⅱ, Ⅲ, Ⅳ, and Ⅴ in girls were 8.55 , 10.17, 11.18, and 13.78 years old, respectively. Based on overweight and obesity, stratified analysis showed that earlier pubertal onset among overweight/obesity children, and the key milestones for pubertal initiation were testicular volume reaching 4 mL in boys and breast Tanner II in girls for 10.29, 10.83; 8.18, 9.00 years.
Conclusion
Overweight and obesity are associated with earlier pubertal initiation,but there are certain gender and developmental stage specific patterns.

Chinese Journal of Experimental Traditional Medical Formulae 2026;32(9):163-170
SkinPro Ointment is an emulsion-based preparation derived from a traditional Tibetan medical empirical formula and developed using modern pharmaceutical technology. It is an exclusive patented product of Tibet Hairong Tangguo Pharmaceutical Co. Ltd. and has been listed as a National Protected Traditional Chinese Medicine Variety, the Pharmacopoeia of the People's Republic of China, and classified as a Category B product in the National Basic Medical Insurance Catalog. The ointment possesses the functions of clearing heat and drying dampness, activating blood circulation and dispelling wind, relieving itching and reducing inflammation. Clinically, it is used for skin pruritus caused by dampness-heat accumulation or blood-heat with wind-dryness, as well as pruritic skin diseases such as neurodermatitis, eczema, tinea pedis, and psoriasis. To clarify the standards for its clinical application and promote rational drug use, a consensus working group comprising 34 national experts in dermatology, evidence-based medicine, and pharmacy was established. Through expert interviews, the nominal group technique, and questionnaire surveys, 15 clinical issues were identified. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) evidence grading system was employed to assess the quality of evidence, leading to the formulation of the Expert Consensus on the Clinical Application of SkinPro Ointment. This consensus specifies that the intended users are physicians and pharmacists in medical institutions at all levels. It standardizes the clinical application of the ointment, including syndrome characteristics, dosage and course of treatment, combination therapy, precautions, and contraindications. Recommendations and consensus suggestions were formed addressing the 15 clinical issues, covering the following key areas: ①Indications and TCM syndromes: In TCM, the ointment mainly treats conditions such as "damp sores" (Shichuang), "white scaling" (Baibi), "collar sores" (Shelingchuang), and "damp foot Qi" (Jiaoshiqi), corresponding to eczema, psoriasis, neurodermatitis, and tinea pedis in Western medicine. The relevant TCM syndromes are identified as dampness-heat accumulation or blood-heat with wind-dryness. ②Usage and dosage: For external use, apply to the affected area 3 times daily. The dosage should follow the fingertip unit (FTU) principle. A treatment course of 1-2 weeks is recommended for mild to moderate cases; for serious cases, the course should be followed as prescribed by a physician. ③Combined therapy: The ointment can be used as monotherapy for mild cases. For moderate to severe cases, combination therapy is recommended, with reference to relevant clinical guidelines. ④Safety: Common adverse reactions include skin rashes, pruritus, and erythema. The ointment is contraindicated in patients with broken skin or obvious exudation at the affected area, as well as in patients with known hypersensitivity to any of its components. Contact with sensitive areas such as the eyes and oral mucosa should be avoided. Modern research shows that the ointment also has potential efficacy in other dermatological conditions, such as adult atopic dermatitis, tinea cruris, exfoliative keratolysis, acne vulgaris, and Malassezia folliculitis. This consensus provides a scientific basis for promoting the rational clinical use of SkinPro Ointment, improving its therapeutic efficacy, and reducing medication risks. Future updates will be dynamically revised according to emerging clinical issues and new evidence.
