[PMID: 38310056 DOI: 10.1016/j.crad.2024.01.009] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/19/2023] [Revised: 12/03/2023] [Accepted: 01/06/2024] [Indexed: 02/05/2024]
Abstract
AIM To determine whether net water uptake (NWU) based on automated software evaluation could predict futile recanalisation in patients with acute anterior circulation large-vessel occlusion (LVO). MATERIALS AND METHODS Patients with acute anterior circulation LVO undergoing mechanical thrombectomy in Jinling Hospital were evaluated retrospectively. NWU and other baseline data were evaluated by performing univariate and multivariate analyses. The primary endpoint was 90-day modified Rankin scale score ≥3. A nomogram to predict poor clinical outcomes was developed based on multivariate logistic regression analysis. RESULTS Overall, 135 patients who underwent thrombectomy with a TICI grade ≥2b were enrolled. In multivariate logistic regression analysis, the following factors were identified as independent predictors of futile recanalisation: age (odds ratio [OR]: 1.055, 95 % confidence interval [CI]: 1.004-1.110, p=0.035), female (OR: 0.289, 95 % CI: 0.098-0.850, p=0.024), hypertension (OR: 3.182, 95 % CI: 1.160-8.728, p=0.025), high blood glucose level (OR: 1.36, 95 % CI: 1.087-1.701, p=0.007), admission National Institutes of Health Stroke Scale score (OR: 1.082, 95 % CI: 1.003-1.168, p=0.043), and NWU (OR: 1.312, 95 % CI: 1.038-1.659, p=0.023). CONCLUSIONS NWU based on Alberta Stroke Program Early Computed Tomography (CT) Score (ASPECTS) could be used to predict the occurrence of futile recanalisation in patients with acute anterior circulation LVO ischaemic stroke.

Abstract
Objective: To analyze the status of respiratory pathogen detection and the clinical features in children with Mycoplasma pneumoniae pneumonia (MPP). Methods: A prospective, multicenter study was conducted to collect clinical data, including medical history, laboratory examinations and multiplex PCR tests of children diagnosed with MPP from 4 hospitals in China between November 15th and December 20th, 2023. The multiplex PCR results and clinical characteristics of MPP children in different regions were analyzed. The children were divided into severe and mild groups according to the severity of the disease. Patients in the severe group were further divided into Mycoplasma pneumoniae (MP) alone and Multi-pathogen co-detection groups based on whether other pathogens were detected besides MP, to analyze the influence of respiratory pathogen co-detection rate on the severity of the disease. Mann-Whitney rank sum test and Chi-square test were used to compare data between independent groups. Results: A total of 298 children, 136 males and 162 females, were enrolled in this study, including 204 children in the severe group with an onset age of 7.0 (6.0, 8.0) years, and 94 children in the mild group with an onset age of 6.5 (4.0, 7.8) years. The level of C-reactive protein, D-dimer, lactic dehydrogenase (LDH) were significantly higher (10.0 (5.0, 18.0) vs. 5.0 (5.0, 7.5) mg/L, 0.6 (0.4, 1.1) vs. 0.5 (0.3, 0.6) mg/L, 337 (286, 431) vs. 314 (271, 393) U/L, Z=2.02, 2.50, 3.05, all P<0.05), and the length of hospitalization was significantly longer in the severe group compared with those in mild group (6.0 (6.0, 7.0) vs. 5.0 (4.0, 6.0) d, Z=4.37, P<0.05). The time from onset to admission in severe MPP children was significantly shorter than that in mild MPP children (6.0 (5.0, 9.5) vs. 9.0 (7.0, 13.0) d, Z=2.23, P=0.026). All patients completed the multiplex PCR test, with 142 cases (47.7%) MPP children detected with 21 pathogens including adenovirus 25 cases (8.4%), human coronavirus 23 cases (7.7%), rhinovirus 21 cases (7.0%), Streptococcus pneumoniae 21 cases (7.0%), influenza A virus 18 cases (6.0%). The pathogens with the highest detection rates in Tianjin, Shanghai, Wenzhou and Chengdu were Staphylococcus aureus at 10.7% (8/75), adenovirus at 13.0% (10/77), adenovirus at 15.3% (9/59), and both rhinovirus and Haemophilus influenzae at 11.5% (10/87) each. The multi-pathogen co-detection rate in severe MPP children was significantly higher than that in mild MPP group (52.9% (108/204) vs. 36.2% (34/94), χ²=10.62,P=0.005). Among severe MPP children, there are 89 cases in the multi-pathogen co-detection group and 73 cases in the simple MPP group. The levels of LDH, D-dimer and neutrophil counts in the multi-pathogen co-detection group were significantly higher than those in the simple MPP group (348 (284, 422) vs. 307 (270, 358) U/L, 0.8 (0.5, 1.5) vs. 0.6 (0.4, 1.0) mg/L, 4.99 (3.66, 6.89)×109 vs. 4.06 (2.91, 5.65)×109/L, Z=5.17, 4.99, 6.11, all P<0.05). Conclusions: The co-detection rate of respiratory pathogens, LDH and D-dimer in children with severe MPP were higher than those with mild MPP. Among severe MPP children the stress response of children in co-detection group was more serious than that of children with simple MPP.

Perioperative Diaphragm Dysfunction. J Clin Med 2024; 13:519. [PMID: 38256653 PMCID: PMC10816119 DOI: 10.3390/jcm13020519] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/06/2023] [Revised: 01/07/2024] [Accepted: 01/15/2024] [Indexed: 01/24/2024] Open
Abstract
Diaphragm Dysfunction (DD) is a respiratory disorder with multiple causes. Although both unilateral and bilateral DD could ultimately lead to respiratory failure, the former is more common. Increasing research has recently delved into perioperative diaphragm protection. It has been established that DD promotes atelectasis development by affecting lung and chest wall mechanics. Diaphragm function must be specifically assessed for clinicians to optimally select an anesthetic approach, prepare for adequate monitoring, and implement the perioperative plan. Recent technological advancements, including dynamic MRI, ultrasound, and esophageal manometry, have critically aided disease diagnosis and management. In this context, it is noteworthy that therapeutic approaches for DD vary depending on its etiology and include various interventions, either noninvasive or invasive, aimed at promoting diaphragm recruitment. This review aims to unravel alternative anesthetic and operative strategies that minimize postoperative dysfunction by elucidating the identification of patients at a higher risk of DD and procedures that could cause postoperative DD, facilitating the recognition and avoidance of anesthetic and surgical interventions likely to impair diaphragmatic function.

Abstract
Objective: To investigate the concern about pollen broadcasting in Chinese population from multiple dimensions and to understand the information about allergic rhinitis (AR) in China by analyzing related factors. Methods: From March 1 to September 30, 2022, a large-scale multi-center cross-sectional survey was conducted based on the Questionnaire Star platform in 21 Chinese hospitals. A total of 7 056 subjects from 7 regions in China: Northeast, North, East, Central, South, Southwest, and Northwest China were included. Basic characteristics (including social demographic characteristics and disease characteristics of AR patients), concern about pollen broadcasting, the willingness of pollen-induced AR (PiAR) patients to receive pollen broadcasting, and the treatment satisfaction rate of AR patients were collected. The chi-square test, multivariate linear regression model, and Logistic regression analysis were used to analyze the concern about pollen broadcasting in the Chinese population and related factors from multiple dimensions. Results: Among 7 056 subjects, 23.02% were concerned about pollen broadcasting. Among 3 176 self-reported AR and 1 019 PiAR patients, 25.60% and 39.16% were concerned about pollen broadcasting, respectively, which was higher than that of non-AR or non-PiAR subjects (χ2 value was 21.74 and 175.11, respectively, both P<0.001). Among AR patients, the proportion of spring and autumn allergen-positive patients concerned about pollen broadcasting was higher than that in perennial allergen-positive patients (χ2 value was 20.90 and 19.51, respectively, both P<0.001). The proportion of AR patients with asthma, sinusitis, allergic conjunctivitis, and cardiovascular and cerebrovascular diseases was higher than those without complications (χ2 value was 50.83, 21.97, 56.78, 7.62, respectively, all P<0.05). The proportion of AR patients in North China who could find pollen broadcasting locally was 31.01%, significantly higher than those in other regions (all P<0.05). Multivariate linear regression model analysis showed that among PiAR patients, those with higher per capita household income and higher AR disease cognition levels had been concerned about pollen broadcasting in the past, and those complicated with allergic conjunctivitis had stronger intention to receive pollen broadcasting (B value was 0.24, 0.13, 0.66, 0.47, respectively, all P<0.05). The higher the disease cognition level of PiAR patients, the stronger their willingness to actively participate in treatment (R2=0.72, P<0.001). Only 18.89% of AR patients felt satisfied with the treatment effect. Logistic regression analysis showed that in AR patients, the treatment satisfaction rate was significantly higher among those concerned about pollen broadcasting compared to those who were not (OR=1.83, P<0.001). Conclusions: Currently, the dissemination of pollen broadcasting in China is hindered by various factors such as disease cognition level. The treatment satisfaction among AR patients remains unsatisfactory.

NETO2-GluK2 interaction contributes to postoperative pain hypersensitivity through inducing PKCγ activation and synaptic incorporation of AMPA receptor GluR1 subunits in rat dorsal horn. Neurosci Lett 2023; 813:137430. [PMID: 37544581 DOI: 10.1016/j.neulet.2023.137430] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2023] [Revised: 08/02/2023] [Accepted: 08/03/2023] [Indexed: 08/08/2023]
Abstract
Important roles in the initiation and maintenance of postoperative pain are played by the functional control of kainate (KA) and α-amino-3-hydroxy-5-methyl-4-isoxazole propionate (AMPA) receptors in the rat dorsal horn (DH). However, the mechanisms underpinning the cross-talk between spinal KA and AMPA receptors in postoperative pain are poorly understood. We hypothesized that after the rat's plantar incision, the synaptic incorporation of AMPA receptor GluR1 subunits in the DH ipsilateral to the incision would increase due to the interaction between GluK2 and neuropilin tolloid-like 2 (NETO2). Our findings showed that incision stimuli caused severe pain responses, as measured by cumulative pain scores. GluK2-NETO2 but not GluK2-NETO1interaction was upregulated in ipsilateral dorsal horn neurons (DHNs) at 6 h post-incision. At 6 h post-incision, NETO2 small interfering ribonucleic acid (siRNA) intrathecal pretreatment increased mechanical withdrawal thresholds to von Freys and decreased ipsilateral paw cumulative pain scores. Further, PKCγactivation and synaptic abundance of GluK2 and GluR1 subunits in the ipsilateral DH were decreased by intrathecal pretreatment with NETO2 siRNA at 6 h post-incision. In conclusion, our findings imply that GluK2-NETO2 interaction could trigger PKCγactivation and the synaptic incorporation of AMPA receptor GluR1 subunits in rat DHs, which in turn led to the enhanced pain hypersensitivity after surgery. It sheds light on the interplay between KA and AMPA receptors in DHNs, which is thought to contribute to postoperative pain.

The Utility of Peripherally Restricted Kappa-Opioid Receptor Agonists for Inhibiting Below-Level Pain After Spinal Cord Injury in Mice. Neuroscience 2023; 527:92-102.

Abstract
Pain after spinal cord injury (SCI) can be difficult to treat. Drugs that target the opioid receptor (OR) outside the central nervous system (CNS) have gained increasing interest in pain control owing to their low risk of central side effects. Asimadoline and ICI-204448 are believed to be peripherally restricted KOR agonists withlimited access to the CNS. This study examined whether they can attenuate pain hypersensitivity in mice subjected to a contusive T10 SCI. Subcutaneous (s.c.) injection of asimadoline (5, 20 mg/kg) and ICI-204448 (1, 10 mg/kg) inhibited heat hypersensitivity at both doses, but only attenuated mechanical hypersensitivity at the high dose. However, the high-dose asimadoline adversely affected animals' exploratory performance in SCI mice and caused aversion, suggesting CNS drug penetration. In contrast, high-dose ICI-204448 did not impair exploration and remained effective in reducing both mechanical and heat hypersensitivities after SCI. Accordingly, we chose to examine the potential peripheral neuronal mechanism for ICI-204448-induced pain inhibition by conducting in vivo calcium imaging of dorsal root ganglion (DRG) in Pirt-GCaMP6s+/- mice. High-dose ICI-204448 (10 mg/kg, s.c.) attenuated the increased fluorescence intensity of lumbar DRG neurons activated by a noxious pinch (400 g) stimulation in SCI mice. In conclusion, systemic administration of ICI-204448 achieved SCI pain inhibition at doses that did not induce notable side effects and attenuated DRG neuronal excitability which may partly contribute to its pain inhibition. These findings suggest that peripherally restricted KOR agonists may be useful for treating SCI pain, but the therapeutic window must be carefully examined.

Abstract
OBJECTIVES The aim of this article was to explore the association between adverse childhood experiences (ACEs) and the Charlson comorbidity index (CCI) and to provide valuable information for public health professionals and policymakers to improve quality of life and reduce mortality. STUDY DESIGN A cross-sectional analysis was conducted using data pooled from the 2020 Behavioral Risk Factor Surveillance System (BRFSS). METHODS This study involved 102,393 US adult participants from the 2020 BRFSS. The zero-inflated negative binomial (ZINB) and mixed graphical model (MGM) models were used to explore the effect of ACEs on CCI and the interaction between ACEs. RESULTS In the count part of the model (CCI ≥0), sexual abuse had the strongest association with CCI (relative risk [RR] = 1.111, P < 0.001). In the logit part of the model (CCI = 0), the likelihood of having CCI equal to 0 decreased by 23.0% for household substance abuse, which was the highest percentage decrease for all ACEs. Compared to those with ACE scores equal to 0, individuals with ACE scores ≥4 have an expected CCI RR of 1.222, and the likelihood of having CCI equal to 0 decreased by 50.2%. Household substance abuse and incarceration history in the home had the strongest association among interactions of ACEs (0.85). CONCLUSIONS Associations between ACEs and CCI were observed in this study, and these associations differed between genders. The findings of this study provide data to design strategies for disease prevention and improvement of quality of life.

Abstract
Objective: To detect the cell-free DNA of Mycobacterium tuberculosis (Cf-TB) in the cerebrospinal fluid (CSF) of patients with tuberculous meningitis (TBM), and to assess the diagnostic value of this method for TBM. Methods: We prospectively included patients with suspected meningitis from the Department of Tuberculosis, Beijing Chest Hospital, Department of Neurology, Beijing Chaoyang Hospital and Department of Neurology, 263 Hospital of the People's Liberation Army from September 2019 to March 2022. A total of 189 patients were included in this study. Among them, 116 were male and 73 were female, aged from 7 to 85 years, with an average of (38.5±19.1) years. The CSF specimens of the patients were collected for Cf-TB, MTB culture and Xpert MTB/RIF. SPSS 20.0 was used for statistical analysis and the difference was statistically significant with P<0.05. Results: Among the 189 patients, there were 127 patients in the TBM group and 62 patients in the non-TBM group. The sensitivity of Cf-TB was 50.4% (95%CI 41.4%-59.3%), the specificity was 100% (95%CI 92.7%-100.0%), the positive predictive value was 100% (95%CI 92.9%-100.0%), and the negative predictive value was 49.6% (95%CI 40.6%-58.6%). Using clinical diagnosis as the gold standard, the sensitivity of Cf-TB was 50.4% (64/127), which was significantly higher than that of MTB culture (8.7%, 11/127) and Xpert MTB/RIF (15.7%,20/127) (all P<0.001). Using etiology as the gold standard, the sensitivity of Cf-TB was 72.7% (24/33), which was significantly higher than that of MTB culture [33.3%, 11/33, (χ2=10.28, P=0.001)] and was similar to Xpert MTB/RIF (60.6%, 20/33) (χ2=1.091, P=0.296). Conclusion: The sensitivity of the Cf-TB test was significantly higher than that of CSF MTB culture and Xpert MTB/RIF. Cf-TB may provide evidence for earlier diagnosis and treatment of TBM.

The Preemptive Analgesic Effect of Capsaicin Involves Attenuations of Epidermal Keratinocytes Proliferation and Expression of Pro-Inflammatory Mediators After Plantar Incision in Rats. J Pain Res 2023; 16:141-149.

Abstract
Purpose Subcutaneous infiltration of capsaicin, which initially activates transient receptor potential vanilloid 1 (TRPV1) receptors, can subsequently desensitize TRPV1-expressing nociceptors and induce analgesia in different pain models. Yet, whether the modulation of keratinocytes may also contribute to the analgesic action of capsaicin treatment remains unclear. In a rat model of postoperative pain, we tested the hypothesis that subcutaneous injection of capsaicin inhibited the proliferation of epidermal keratinocytes and their expression of pronociceptive inflammatory mediators after plantar incision. Methods The plantar incision model was carried out in the current study. Behavioral tests were used to evaluate postoperative pain-related behaviors in rats. Immunohistochemistry was used to investigate epidermal keratinocytes proliferation and expression of pro-inflammatory mediators in keratinocytes in rats. Results Behaviorally, plantar incision induced robust postoperative pain hypersensitivity. However, subcutaneous pretreatment of capsaicin (1%) but not the vehicle, prevented the development of postoperative pain. There was an increased proliferation of keratinocytes and the expressions of interleukin-1β (IL-1β) and tumour necrosis factor-alpha (TNF-α) in keratinocytes at 3 d and 7 d after plantar incision. However, these changes were also significantly attenuated by capsaicin pretreatment. Conclusion Our findings suggest that capsaicin pretreatment may inhibit incision-induced keratinocytes proliferation and reduce their expression of pronociceptive inflammatory mediators under postoperative pain conditions, which represents a peripheral non-neuronal mechanism of capsaicin-induced analgesia.

Abstract
With the improvement of people's living standards and rapid economic development, the incidence of diabetes mellitus (DM) is increasing in most parts of the world. DM presents an important potential threat to human health. In the present study, a model of diabetes in female mice was established, and fasting blood glucose was detected at week 4, after which the biochemical profiles were evaluated by histopathological analysis. The success rate of modeling in the normal control (NC) group and the low/ middle/high-dose streptozotocin (STZ) group were 0, 0, 25% and 60%, respectively. In the middle-dose and high-dose STZ groups, the liver index was increased significantly compared with the NC group (p⟨0.05). The blood biochemical indicators of total cholesterol and low density lipoprotein cholesterol in three STZ injection groups were as follows: alanine aminotransferase and aspartate transaminase in middle- and high-dose STZ groups, high-density lipoprotein cholesterol and serum creatinine in the high-dose STZ group, and blood urea nitrogen in the middle-dose STZ group were significantly increased (p⟨0.05). The level of total triglycerides was lower, obviously, in the high-dose STZ group than in the NC group (p⟨0.05). The mice showed marked steatosis, green-dyed fiber tissue coloring in varying degrees, and the contour of the hepatic lobules basically disappeared in STZ injection groups. The results suggest that to establish a diabetes model for female ICR mice, the optimum dose of STZ is 100 mg/kg.

Rectifying cow infertility under heat stress by immunization against inhibin and supplementation of progesterone. Domest Anim Endocrinol 2022; 80:106726. [PMID: 35413656 DOI: 10.1016/j.domaniend.2022.106726] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/03/2021] [Revised: 03/03/2022] [Accepted: 03/04/2022] [Indexed: 11/25/2022]
Abstract
This study was undertaken for the development of novel techniques that are based on immunoneutralization of inhibin bioactivity to improve Holstein cow fertility. A series of 4 experiments were carried out on 2 farms that were located in subtropical or temperate regions, to test the effects of immunization against inhibin alpha subunit on cow fertility under varying degrees of heat stress conditions. Though immunization against inhibin alone improved conception rate (CR) after TAI moderately in cows under mild heat stress conditions, the treatment plus progesterone supplementation substantially enhanced CR in the range of 25 to 35 percentages from severe heat stress to comfortable weather conditions. There existed an additive effect between immunization against inhibin and progesterone supplementation that maximally enhanced CR. Further, immunization against inhibin increased both FSH and activin A concentrations in blood during both follicular and luteal phases. It also significantly increased blood concentrations of E2 in the follicular phase but decreased P4 concentrations during the early pregnancy. However, interferon-tau concentrations in blood around the time of pregnancy recognition were doubled in the inhibin immunized cows. In conclusion, immunization against inhibin plus P4 treatment enhances ovarian follicle and the subsequent early embryo developments that help to greatly improve the fertility of Holstein dairy cows.

Modulation of Trans-Synaptic Neurexin-Neuroligin Interaction in Pathological Pain. Cells 2022; 11:cells11121940.

Abstract
Synapses serve as the interface for the transmission of information between neurons in the central nervous system. The structural and functional characteristics of synapses are highly dynamic, exhibiting extensive plasticity that is shaped by neural activity and regulated primarily by trans-synaptic cell-adhesion molecules (CAMs). Prototypical trans-synaptic CAMs, such as neurexins (Nrxs) and neuroligins (Nlgs), directly regulate the assembly of presynaptic and postsynaptic molecules, including synaptic vesicles, active zone proteins, and receptors. Therefore, the trans-synaptic adhesion mechanisms mediated by Nrx-Nlg interaction can contribute to a range of synaptopathies in the context of pathological pain and other neurological disorders. The present review provides an overview of the current understanding of the roles of Nrx-Nlg interaction in the regulation of trans-synaptic connections, with a specific focus on Nrx and Nlg structures, the dynamic shaping of synaptic function, and the dysregulation of Nrx-Nlg in pathological pain. Additionally, we discuss a range of proteins capable of modulating Nrx-Nlg interactions at the synaptic cleft, with the objective of providing a foundation to guide the future development of novel therapeutic agents for managing pathological pain.

SP1-induced lncRNA ZFPM2 antisense RNA 1 (ZFPM2-AS1) aggravates glioma progression via the miR-515-5p/Superoxide dismutase 2 (SOD2) axis. Bioengineered 2021; 12:2299-2310. [PMID: 34077295 PMCID: PMC8806534 DOI: 10.1080/21655979.2021.1934241] [Citation(s) in RCA: 27] [Impact Index Per Article: 9.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/25/2021] [Revised: 05/18/2021] [Accepted: 05/19/2021] [Indexed: 12/14/2022] Open
Abstract
Glioma is a common life-threatening tumor with high malignancy and high invasiveness. LncRNA ZFPM2 antisense RNA 1 (ZFPM2-AS1) was confirmed to be implicated in numerous tumors, while its biological function and mechanism have not been thoroughly understood in glioma. The gene expression was measured by RT-qPCR. Cell proliferation, cell cycle, and cell apoptosis of glioma cells were validated by CCK-8, colony formation, flow cytometry and TUNEL assays. The effect of ZFPM2-AS1 on tumor growth was verified by in vivo assay. The exploration on ZFPM2-AS1-mediated mechanism was carried out via ChIP, luciferase reporter, and RIP assays. In the present study, ZFPM2-AS1 was demonstrated as a highly-expressed lncRNA in glioma tissues and cells. ZFPM2-AS1 silencing suppressed cell proliferation and cell cycle, but facilitated cell apoptosis. In addition, the inhibitive effect of silenced ZFPM2-AS1 was also observed in tumor growth. Furthermore, we found that SP1 interacted with ZFPM2-AS1 promoter to transcriptionally activate ZFPM2-AS1 expression. Moreover, ZFPM2-AS1 was identified as a competing endogenous RNA (ceRNA) for miR-515-5p to target SOD2. Rescue assays verified that SOD2 overexpression partially abolished the suppressive impact of ZFPM2-AS1 silencing on glioma cell growth. In conclusion, this study corroborated the regulatory mechanism of SP1/ZFPM2-AS1/miR-515-5p/SOD2 axis in glioma, indicating that targeting ZFPM2-AS1 might be an effective way to treat glioma.

Abstract
Objective: To prepare the modified hyaluronic acid viscous hydrogel loaded with sliver particles and to explore the roles and mechanism of the hydrogel in healing of full-thickness skin defect wounds with bacterial colonization in mice. Methods: The experimental research method was adopted. Dopamine modified hyaluronic acid (HA-DA) and phenylboric acid modified hyaluronic acid (HA-PBA) were prepared, and their characteristic peaks were detected by Fourier-transform infrared spectroscopy. Different mass of acrylamides was added to HA-DA and HA-PBA to prepare the viscous hydrogel with mass fraction of acrylamide in 10%, 15%, and 20%. The gelation of the viscous hydrogel with mass fraction of acrylamide in 20% was observed in the state of tilt and inversion at 37 ℃, and the storage modulus and loss modulus of the above 3 kinds of viscous hydrogels were detected by rotational rheometer. The sliver-loaded viscous hydrogel was prepared by adding nano silver ions to the viscous hydrogel with mass fraction of acrylamide in 20%. The concentration of silver ions released by sliver-loaded viscous hydrogel was measured by inductively coupled plasma mass spectrometer, and the cumulative release rate of silver ion was calculated (n=5). The mouse fibroblasts L929 were divided into phosphate buffered saline (PBS) group, viscous hydrogel group, and sliver-loaded viscous hydrogel group, which were dealt correspondingly, and the cell survival was detected by cell counting kit 8 method after 1, 2, and 3 d of culture (n=5). Twenty-four male C57BL/6 mice aged 6-8 weeks were selected, and forty-eight full-thickness skin defect wounds were inflicted and inoculated with the mixture of Escherichia coli and Staphylococcus aureus in the back of the mice, with two wounds in each mouse. The wounds were divided into normal saline group, viscous hydrogel group, and sliver-loaded viscous hydrogel group, which were dealt correspondingly, with 16 wounds in each group, and two wounds in each mouse were divided into different groups. On post injury day (PID) 3, 7, 10, and 14, the wound healing was observed and the wound healing rate was calculated. On PID 3, the colony forming units of Escherichia coli and Staphylococcus aureus in wounds were observed and counted. On PID 14, the epithelized epidermal thickness and the optical density of collagen fiber in wounds were observed and analyzed after hematoxylin eosin staining and Masson staining, respectively. On PID 3, 7, and 10, the expressions of tumor necrosis factor α (TNF-α), transforming growth factor β1 (TGF-β1), and vascular endothelial growth factor (VEGF) were detected by immunohistochemistry. The number of wounds in each index detecting at each time point was four. Data were statistically analyzed with analysis of variance for factorial design, one-way analysis of variance, and Bonferroni correction. Results: The characteristic peaks of HA-PBA were detected at the wave numbers of 1 369 and 1 425 cm-1, indicating that phenylboric acid had been successfully grafted on hyaluronic acid, and the characteristic peaks of HA-DA were detected at the wave numbers of 1 516 and 1 431 cm-1, indicating that dopamine had been successfully grafted on hyaluronic acid. The viscous hydrogel with mass fraction of acrylamide in 20% maintained the stable and no-flow condition of gelation in the state of tilt and inversion at 37 ℃. The storage modulus and loss modulus of the viscous hydrogel increased with the increase of acrylamide content, the storage modulus and loss modulus of the 3 kinds of viscous hydrogels had no obvious changes with the increase of the oscillation frequency or time, and the storage modulus of the 3 kinds of acrylamide hydrogels were greater than the loss modulus. The release of silver ion in the sliver-loaded viscous hydrogel lasted for 7 days, and the cumulative release rate of silver ion was up to 65%. After 1, 2, and 3 d of culture, the cell survival rates in sliver-loaded viscous hydrogel group were significantly lower than those in PBS group and viscous hydrogel group (P<0.05 or P<0.01), while after 1 d of culture, the cell survival rate in viscous hydrogel group was significantly lower than that in PBS group (P<0.01). With extension of time after injury, the wounds of mice in the 3 groups shrank gradually. On PID 3, 7, 10, and 14, the wound healing rates in sliver-loaded viscous hydrogel group were (53.0±3.6)%, (75.3±6.9)%, (93.3±1.2)%, and (96.7±0.8)%, which were significantly higher than (21.8±6.4)%, (53.9±8.2)%, (72.0±7.8)%, and (92.5±0.4)% in normal saline group (P<0.01). On PID 3 and 14, the wound healing rates in sliver-loaded viscous hydrogel group were significantly higher than (43.5±2.4)% and (94.1±1.5)% in viscous hydrogel group (P<0.05). On PID 3 and 10, the wound healing rates in viscous hydrogel group were significantly higher than those in normal saline group (P<0.01). On PID 3, the colony forming units of two bacteria in wound of sliver-loaded viscous hydrogel group were significantly less than those in normal saline group and viscous hydrogel group (P<0.01), while the colony forming units of two bacteria in wound of viscous hydrogel group were significantly less than those in normal saline group (P<0.05). On PID 14, the wounds were basically epithelialized and the epidermis was thicker, with collagen protein content being increased significantly and more orderly arranged collagen in sliver-loaded viscous hydrogel group compared with those in the other 2 groups. On PID 14, the epidermal thickness in wounds of sliver-loaded viscous hydrogel group was significantly increased compared with that in the other two groups (P<0.05), and the optical density of collagen fiber was significantly increased compared with those in normal saline group (P<0.05). On PID 3, the expressions of TGF-β1 and VEGF in wounds of sliver-loaded viscous hydrogel group were significantly higher than those in normal saline group (P<0.05 or P<0.01), while the expression of VEGF in wounds of viscous hydrogel group was significantly higher than that in normal saline group (P<0.01). On PID 7, the expression of TGF-β1 in wounds of sliver-loaded viscous hydrogel group was significantly higher than that in the other 2 groups (P<0.01), and the expression of VEGF was significantly higher than that in normal saline group (P<0.01). On PID 10, the expression of TNF-α in wounds of sliver-loaded viscous hydrogel group was significantly lower than that in normal saline group (P<0.05), the expressions of TGF-β1 and VEGF in wounds of sliver-loaded viscous hydrogel group were significantly higher than those in normal saline group (P<0.05 or P<0.01), and the expression of VEGF in wounds of sliver-loaded viscous hydrogel group was significantly higher than that in viscous hydrogel group (P<0.05). Conclusions: The sliver-loaded viscous hydrogel prepared in this study has good stability and elasticity, which can continuously release silver ions and help to accelerate the healing of full-thickness defect wounds with bacterial colonization in mice. Besides, the sliver-loaded viscous hydrogel has low biological toxicity and can promote re-epithelialization, collagen deposition as well as angiogenesis of wounds, which may be related to the infiltration and regression of inflammatory cells.

Intrathecal Injection of GRIP-siRNA Reduces Postoperative Synaptic Abundance of Kainate Receptor GluK2 Subunits in Rat Dorsal Horns and Pain Hypersensitivity. Neurochem Res 2021; 46:1771-1780.

Abstract
The mechanisms underlying postoperative pain differ from the inflammatory or neuropathic pain. Previous studies have demonstrated that intrathecal α-amino-3-hydroxy-5-methy-4-isoxazole propionate (AMPA) -kainate (KA) receptor antagonist inhibits the guarding pain behavior and mechanical hyperalgesia, indicating a critical role of spinal KA receptors in postoperative pain hypersensitivity. However, how the functional regulations of spinal KA receptor subunits are involved in the postoperative pain hypersensitivity remains elusive. Therefore, in the current study, we investigated the synaptic delivery of spinal KA receptor subunits and the interaction between KA receptor subunits and glutamate receptor-interacting protein (GRIP) during the postoperative pain. Our data indicated that plantar incision induced the synaptic delivery of GluK2, but not GluK1 or GluK3 in ipsilateral spinal cord dorsal horns. The co-immunoprecipitation showed an increased GluK2 -GRIP interaction in ipsilateral dorsal horn neurons at 6 h post-incision. Interestingly, Intrathecal pretreatment of GRIP siRNA increased the paw withdrawal thresholds to mechanical stimuli and decreased the cumulative pain scores in the paws ipsilateral to the incision at 6 h post-incision. Additionally, Intrathecal pretreatment of GRIP siRNA reduced the synaptic abundance of GluK2 in ipsilateral spinal dorsal horn at 6 h after plantar incision. In general, our data have demonstrated that the GluK2- GRIP interaction-mediated synaptic abundance of GluK2 in dorsal horn neurons plays an important role in the postoperative pain hypersensitivity. Disrupting the GluK2- GRIP interaction may provide a new approach for relieving postoperative pain.

Abstract
OBJECTIVE The purpose of this study was to illustrate the role of NAA10 in aggravating the malignant progression of renal cell carcinoma (RCC) by upregulating UPK1B. PATIENTS AND METHODS NAA10 levels in RCC tissues and paracancerous tissues were detected. Thereafter, the potential relationship between NAA10 level and clinical parameters of RCC patients was analyzed. After knockdown of NAA10, changes in proliferative potential of 786-O and Caki-1 cells were examined by cell counting kit-8 (CCK-8), colony formation and 5-Ethynyl-2'-deoxyuridine (EdU) assay. Finally, the regulatory role of NAA10 in the downstream gene UPK1B and the involvement of UPK1B in the development of RCC were determined via rescue experiments. RESULTS NAA10 was upregulated in RCC tissues than paracancerous tissues. Tumor staging was much worse in RCC patients expressing a higher level of NAA10. Knockdown of NAA10 inhibited proliferative potential and downregulated UPK1B in RCC cells. Besides, NAA10 level was identified to be positively linked to UPK1B level in RCC tissues. At last, overexpression of UPK1B was able to abolish the inhibitory effect of silenced NAA10 on RCC proliferation. CONCLUSIONS NAA10 level is closely linked to tumor staging and poor prognosis in RCC patients. NAA10 aggravates the malignant progression of RCC by upregulating UPK1B and may be a specific biomarker in RCC.

Abstract
Epidermal keratinocytes play a vital role in restoration of the intact skin barrier during wound healing. The negative effect of hyperglycemia may prolong the wound healing process. Epidermal keratinocytes have been demonstrated to modulate and directly initiate nociceptive responses in rat models of fractures and chemotherapy-induced neuropathic pain. However, it is unclear whether epidermal keratinocytes are involved in the development and maintenance of incisional pain in nondiabetic or diabetic animals. In the current study, using behavioral tests and immunohistochemistry, we investigated the differential keratinocytes proliferation and expression of pronociceptive inflammatory mediators in keratinocytes in C57BL/6J mice and diabetic KK mice. Our data showed that plantar incision induced postoperative pain hypersensitivity in both C57BL/6J mice and KK mice, while the duration of postoperative pain hypersensitivity in KK mice was longer than that in C57BL/6J mice. Moreover, plantar incision induced the keratinocytes proliferation and expression of IL-1β and TNF-α in keratinocytes in both C57BL/6J mice and KK mice. Interestingly, compared to C57BL/6J mice, the slower and more persistent proliferation of keratinocytes and expression of IL-1β and TNF-α in keratinocytes were observed in KK mice. Together, our study suggested that plantar incision may induce the differential keratinocytes proliferation and expression of IL-1β and TNF-α in kertinocytes in diabetic and nondiabetic animals, which might be associated with the development and maintenance differences in diabetic and nondiabetic postoperative pain.

Ubiquitin-mediated receptor degradation contributes to development of tolerance to MrgC agonist-induced pain inhibition in neuropathic rats. Pain 2021; 162:1082-1094.

Abstract
ABSTRACT Agonists to subtype C of the Mas-related G-protein-coupled receptors (MrgC) induce pain inhibition after intrathecal (i.t.) administration in rodent models of nerve injury. Here, we investigated whether tolerance develops after repeated MrgC agonist treatments and examined the underlying mechanisms. In animal behavior studies conducted in male rats at 4 to 5 weeks after an L5 spinal nerve ligation (SNL), the ability of dipeptide MrgC agonist JHU58 (0.1 mM, 10 μL, i.t.) to inhibit mechanical and heat hypersensitivity decreased after 3 days of treatment with a tolerance-inducing dose (0.5 mM, 10 μL, i.t., twice/day). In HEK293T cells, acute treatment with JHU58 or BAM8-22 (a large peptide MrgC agonist) led to MrgC endocytosis from the cell membrane and later sorting to the membrane for reinsertion. However, chronic exposure to JHU58 increased the coupling of MrgC to β-arrestin-2 and led to the ubiquitination and degradation of MrgC. Importantly, pretreatment with TAK-243 (0.2 mM, 5 μL, i.t.), a small-molecule inhibitor of the ubiquitin-activating enzyme, during tolerance induction attenuated the development of tolerance to JHU58-induced inhibition of mechanical and heat hypersensitivity in SNL rats. Interestingly, morphine analgesia was also decreased in SNL rats that had become tolerant to JHU58, suggesting a cross-tolerance. Furthermore, i.t. pretreatment with TAK-243, which reduced JHU58 tolerance, also attenuated the cross-tolerance to morphine analgesia. These findings suggest that tolerance can develop to MrgC agonist-induced pain inhibition after repeated i.t. administrations. This tolerance development to JHU58 may involve increased coupling of MrgC to β-arrestin-2 and ubiquitin-mediated receptor degradation.

Abstract
Gastric cancer is characterized by the presence of high invasion ability, hypoxia and chemoresistance. Previous studies reported that liver X receptor α (LXRα) was involved in epithelial-mesenchymal transition (EMT) of gastric cancer cells. However, hypoxia-mediated EMT and the role of LXRα in gastric cancer remained elusive. In this study, we demonstrated that LXRa mRNA and protein levels were up-regulated by hypoxia treatment and LXRα played an important role in HIF-1 dimer induced-EMT. The putative HIF-1α binding site was identified in the LXRa promoter. Expression of LXRα and HIF-1α was significantly up-regulated in gastric cancer tissues compared to that in normal tissues. More importantly, we noticed that the expression of LXRα and HIF-1α was significantly correlated. Taken together, these data suggested that LXRα is regulated by the activity and accumulation of HIF-1α and contributes to EMT of gastric cancer cells. This suggests that targeting LXRα might be a potential approach for improving survival of gastric cancer patients.

Abstract
Objective: To analyze the characteristics and citations of articles in National Medical Journal of China (NMJC) during 2016, and to discuss the academic level and quality of the journal. Methods: All the literature published in NMJC during 2016 were retrieved through the Chinese Medical Citation index, and the citation frequency data in China's core journals of science and technology from January 2017 to December 2018 was obtained through Institute of Scientific and Technical Information of China. The citation status of articles published in NMJC was statistically analyzed by the method of literature metrology. The main indicators included the citation rate of articles published in each year, the citation frequency of all articles, the citation status of individual papers and authors, the regional and high-yield institution distribution of cited authors, and the main citation journals. Results: In 2016, a total of 962 articles were published in 22 columns of NMJC. The total number of published pages was 3 940, and the average number of articles was 4.09 pages. A total of 28 key topics have been published. The total citation was 2 077 times, with 2.16 times per paper. Among them, 322 papers were not cited, accounting for 33.47%. The maximum citation frequency of a single paper was 66 times. There were good citations in the columns of Guidelines, Epidemiology, New technology and methods, Clinical research and Editorial. Oncology, neurology/psychiatry, imaging/ultrasound/radiology, respiratory medicine and orthopedics accounted for a large part [40.43% (389 articles)]. Articles in neurosurgery, respiratory medicine, preventive medicine and gastrointestinal surgery were all cited with high frequency (all ≥2.75 times/article). A total of 483(50.21%) articles had obtained fund support, and the rate (68.12%) of them cited was slightly higher than that of articles without fund support (64.93%). A total of 23 articles were cited ≥10 times, and 16 first authors were cited ≥10 times. In addation, 26 corresponding authors were cited ≥10 times and 10 institutions were cited more than 15 times. The authors of the cited papers were distributed in 29 provinces (autonomous regions, municipalities directly under the central government), and there were more articles and higher total citation frequency in Beijing, Shanghai, Jiangsu and Tianjin. From 2017 to 2018, papers published in NMJC were cited 2 077 times by a total of 490 journals. Conclusions: The guidelines published in NMJC is highly cited. The editorial department should adjust the column setting timely, strengthen the planning of key topic selection and the solicitation and publicity of excellent papers, and further improve the influence of the magazine.

Abstract
Objective: To investigate the current trend of breast cancer neoadjuvant therapy and provide reference for the improvement of breast cancer clinical guideline in the future. Methods: Questionnaires of cross-sectional survey were sent to 110 hospitals (breast cancer surgery quantity surpassing 200) between July 2018 and September 2018. The stages and subtypes, therapeutic regimen, treatment assession, operation choice and preforming of patients underwent neoadjuvant therapy were recorded. Results: Neoadjuvant treatment has been performed in all of the 110 hospitals. The total number of breast patients underwent neoadjuvant therapy was about 14 550 (17.0% in surgical patients) in 2017. For all of the neoadjuvant patients, the proportion of stageⅡ patients was less than 30% in 81 hospitals, and the proportion of stage Ⅲ was more than 50% in 84 hospitals. The numbers of estrogen receptor (ER) (+ )/human epidermal growth factor receptor-2 (HER-2) (-), ER (-)/HER-2 (+ ) and triple negative subtype breast cancer patients were 3 550 (24.4%), 6 024 (41.4%) and 4 991 (34.3%), respectively. Patient's scruples of relatively delayed operation and weak will of breast conservation after neoadjuvant therapy were the majority reasons for neoadjuvant therapy restriction. Anthracycline followed by taxane was the most usual neoadjuvant therapeutic regimens in 53.6% hospitals, and anthracycline plus taxane was the first choice in 42.7% hospitals. Chemotherapy with targeting therapy was recommended to HER-2 positive neoadjuvant patients in 80.9% hospitals. To assess treatment outcome of neoadjuvant treatment, 42.7% hospitals used MRI in more than 50% patients while the usage rate of MRI was less than 20% in 37.3% hospitals. The proportions of hospital using repeat-marking, tattoo and metal clip as the first method to identify the primary tumor region and lymph nodes were 60.0%, 29.1% and 10.9%, respectively. Breast-conservation rate after neoadjuvant therapy was less than 20% in 87.3% hospitals. Conclusions: Neoadjuvant therapy for breast cancer is widely performed in most hospitals in China, while the proportion of neoadjuvant treatment in patients with operable breast cancer is still low. Meanwhile, the idea of achieving de-escalation operation through neoadjuvant treatment is not promoted and the therapeutic evaluation method of neoadjuvant treatment needs further studies to improve.

Abstract
Abstract
Background
Obstructive sleep apnea (OSA) is closely related to the incidence and progression of coronary artery disease (CAD), but the mechanisms linking OSA and CAD are unclear. C1q/TNF-related protein-9 (CTRP9) is a novel adipokine that protects the heart against ischemic injury and ameliorates cardiac remodeling.
Purpose
We aimed to ascertain the clinical relevance of CTRP9 with OSA prevalence in patients with CAD.
Methods
From August 2016 to March 2019, consecutive eligible patients with CAD (n=154; angina pectoris, n=88; acute myocardial infarction [AMI], n=66) underwent cardiorespiratory polygraphy during hospitalization. OSA was defined as an apnea-hypopnea index (AHI) ≥15 events h–1. Plasma CTRP9 concentrations were measured by ELISA method.
Results
OSA was present in 89 patients (57.8%). CTRP9 levels were significantly decreased in the OSA group than in the non-OSA group (4.7 [4.1–5.2] ng/mL vs. 4.9 [4.4–6.0] ng/mL, P=0.003). The difference between groups was only observed in patients with AMI (3.0 [2.3–4.9] vs. 4.5 [3.2–7.9], P=0.009), but not in patients with AP (5.0 [4.7–5.3] ng/mL vs. 5.1 [4.7–5.9] ng/mL, P=0.571) (Figure 1). Correlation analysis showed that CTRP9 levels were negatively correlated with AHI (r=−0.238, P=0.003) and oxygen desaturation index (r=−0.234, P=0.004), and positively correlated with left ventricular ejection fraction (r=0.251, P=0.004) in all subjects. Multivariate analysis showed that male gender (OR 3.099, 95% CI 1.029–9.330, P=0.044), body mass index (OR 1.148, 95% CI 1.040–1.268, P=0.006), and CTRP9 levels (OR 0.726, 95% CI 0.592–0.890, P=0.002) were independently associated with the prevalence of OSA.
Conclusions
Plasma CTRP9 levels were independently related to the prevalence of OSA in patients with CAD, suggesting that CTRP9 might play a role in the pathogenesis of CAD exacerbated by OSA.

Abstract
OBJECTIVE To investigate the influence of micro ribonucleic acid 200c (miR-200c) on the apoptosis of placental trophoblasts in a rat model of preeclampsia (PE). MATERIALS AND METHODS PE model in rats was established for extracting placental trophoblasts. Overexpression or knockdown of miR-200c was achieved by transfection of miR-200c mimics or inhibitor. Flow cytometry was carried out to detect the apoptotic rate of placental trophoblasts. Dual-luciferase reporter gene assay was performed to detect the interaction of miR-200c with WNT1. Western blotting was applied to determine the changes of protein levels in placental trophoblasts. RESULTS The expression level of miR-200c in placental trophoblasts of PE group was significantly higher than that in control group. The apoptosis rate was (22.45 ± 2.62)%, (6.58 ± 1.28)%, and (9.57 ± 1.35)% in miR-200c mimic group, miR-200c inhibitor group, and control group, respectively, showing statistically significant differences. MiR-200c overexpression downregulated the expression level of anti-apoptotic protein B-cell lymphoma 2 (Bcl-2), but upregulated expression levels of apoptotic proteins Bcl-2-associated X protein (Bax) and active Caspase-3. MiR-200c suppressed WNT1 expression through the interaction with the 3'-untranslated region (3'-UTR) of WNT1. The expressions of WNT1 and β-catenin were up-regulated after miR-200c overexpression, which was reversed by the Wnt/β-catenin pathway activator. CONCLUSIONS MiR-200c is involved in the development and progression of PE through the Wnt/β-catenin signaling pathway.

The association of hematuria on kidney clinicopathologic features and renal outcome in patients with diabetic nephropathy: a biopsy-based study. J Endocrinol Invest 2020; 43:1213-1220.

Abstract
PURPOSE To investigate the relationships between hematuria, clinicopathological features and renal outcomes in patients with biopsy-proven diabetic nephropathy (DN). METHODS This cohort study included 261 patients with DN. Participants were divided into two groups according to number of red blood cells per high-power field (RBC/hpf) in urine sediment: the hematuria (-) group (≤ 3 RBC/hpf) and the hematuria (+) group (> 3 RBC/hpf). Basic clinical parameters were measured at the time of renal biopsy; relationships between hematuria and clinicopathological features and renal outcomes were analyzed. RESULTS Patients in the hematuria (+) group often had overt proteinuria. Interstitial inflammation was more severe in the hematuria (+) group than in the hematuria (-) group. Glomerular arteriolar hyalinosis, interstitial fibrosis and tubular atrophy were comparable between groups. For patients with early DN (eGFR ≥ 60 ml/min/1.73 m2), urinary RBC/hpf at baseline was positively correlated with glomerular classification, interstitial fibrosis/tubular atrophy scores and interstitial inflammation scores. In prognostic analysis, hematuria was associated with a higher risk of progression to end-stage renal disease. Hematuria remained an independent predictor after adjustment for confounding factors such as sex, age, duration of diabetes, serum glucose level, hypertension, cholesterol, eGFR and urine protein excretion, especially in patients with early DN and in male patients. CONCLUSION In this study, hematuria was associated with more severe renal pathologic lesions in patients with DN. The presence of hematuria could be an independent predictor of renal outcome in patients with early DN.

Characterization of on-target adverse events caused by TRK inhibitor therapy. Ann Oncol 2020; 31:1207-1215. [PMID: 32422171 PMCID: PMC8341080 DOI: 10.1016/j.annonc.2020.05.006] [Citation(s) in RCA: 33] [Impact Index Per Article: 8.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/13/2020] [Revised: 05/04/2020] [Accepted: 05/05/2020] [Indexed: 12/11/2022] Open
Abstract
BACKGROUND The tropomyosin receptor kinase (TRK) pathway controls appetite, balance, and pain sensitivity. While these functions are reflected in the on-target adverse events (AEs) observed with TRK inhibition, these AEs remain under-recognized, and pain upon drug withdrawal has not previously been reported. As TRK inhibitors are approved by multiple regulatory agencies for TRK or ROS1 fusion-positive cancers, characterizing these AEs and corresponding management strategies is crucial. PATIENTS AND METHODS Patients with advanced or unresectable solid tumors treated with a TRK inhibitor were retrospectively identified in a search of clinical databases. Among these patients, the frequency, severity, duration, and management outcomes of AEs including weight gain, dizziness or ataxia, and withdrawal pain were characterized. RESULTS Ninety-six patients with 15 unique cancer histologies treated with a TRK inhibitor were identified. Weight gain was observed in 53% [95% confidence interval (CI), 43%-62%] of patients and increased with time on TRK inhibition. Pharmacologic intervention, most commonly with glucagon-like peptide 1 analogs or metformin, appeared to result in stabilization or loss of weight. Dizziness, with or without ataxia, was observed in 41% (95% CI, 31%-51%) of patients with a median time to onset of 2 weeks (range, 3 days to 16 months). TRK inhibitor dose reduction was the most effective intervention for dizziness. Pain upon temporary or permanent TRK inhibitor discontinuation was observed in 35% (95% CI, 24%-46%) of patients; this was more common with longer TRK inhibitor use. TRK inhibitor reinitiation was the most effective intervention for withdrawal pain. CONCLUSIONS TRK inhibition-related AEs including weight gain, dizziness, and withdrawal pain occur in a substantial proportion of patients receiving TRK inhibitors. This safety profile is unique relative to other anticancer therapies and warrants careful monitoring. These on-target toxicities are manageable with pharmacologic intervention and dose modification.
