Epidemiology of Craniofacial Soft Tissue Injury in a Western Chinese Population.

PURPOSE: Craniofacial soft tissue injuries represent a serious public health problem and their epidemiology is extremely variable. The objective of the present study was to analyze and discuss the epidemiological characteristics of 12,816 patients with craniofacial skin soft tissue injuries over a 3-year period. MATERIALS AND METHODS: This retrospective study was conducted in emergency departments of plastic surgery at Xijing Hospitals from 2020 to 2022. Data were collected for the cause of injury, age and gender distribution, localization and frequency of soft tissue injuries, visit time, facial bone fractures, nerve injury, and treatment protocols. All the data were analyzed and performed including descriptive analysis, chi-square test, and logistic regression analyses. RESULTS: A total of 13,574 soft tissue injuries were seen in 12,816 patients. A total to 94.67% (12,133) were single-site injuries, and 5.33% (683) were multiple-site injuries. The male-to-female ratio of 1.62:1. The age group 0 to 9 years accounted is the largest subgroup. The most common etiology of the trauma was collisions, accounted for 51.89%. The forehead (23.54%) was the most common site by the cheeks (14.36%). Two hundred three patients (1.58%) had associated bone fractures. May month had the highest incidence of trauma and February month had the lowest incidence. There are more visits on weekends than on weekdays. 18:00 to 24:00 is the time with the largest number of visits, but there is no statistically significant difference from other time periods. The average time interval between the accident and treatment was 6.8 hours, and the median time was 6 hours. CONCLUSIONS: The incidence of craniofacial soft tissue injuries is related to gender, age, and the cause of trauma. Children between 0 and 9 are the most likely group. Collisions is the main cause of craniofacial soft tissue injuries.

The Complete Mitochondrial Genomes of Two Rock Scallops (Bivalvia: Spondylidae) Indicate Extensive Gene Rearrangements and Adaptive Evolution Compared with Pectinidae.

Different from the diverse family Pectinidae, the Spondylidae is a small group with a single genus that shares the sedentary life habit of cementing themselves to the substrate. However, little information related to the genetic diversity of Spondylidae has been reported. In the present study, the complete mitochondrial genomes of Spondylus versicolor and S. spinosus were sequenced and compared with those of pectinids. The mtDNA of S. versicolor and S. spinosus show similar patterns with respect to genome size, AT content, AT skew, GC skew, and codon usage, and their mitogenomic sizes are longer than most pectinid species. The mtDNA of S. spinosus is 27,566 bp in length, encoding 13 protein-coding genes, 22 transfer RNA genes, and 2 ribosomal RNA genes, while an additional tRNA-Met was found in the mtDNA of S. versicolor, which is 28,600 bp in length. The monophylies of Spondylidae and Pectinidae were well supported, but the internal relationships within Pectinidae remain unresolved due to the paraphyly of the genus Mimachlamy and the controversial position of the tribe Aequipectinini. The gene orders of S. versicolor and S. spinosus are almost identical but differ greatly from species of the Pectinidae, indicating extensive gene rearrangements compared with Pectinidae. Positive selection analysis revealed evidence of adaptive evolution in the branch of Spondylidae. The present study could provide important information with which to understand the evolutionary progress of the diverse and economically significant marine bivalve Pectinoidea.

Regulation of self-renewing neural progenitors by FGF/ERK signaling controls formation of the inferior colliculus.

The embryonic tectum displays an anteroposterior gradient in development and produces the superior colliculus and inferior colliculus. Studies suggest that partition of the tectum is controlled by different strengths and durations of FGF signals originated from the so-called isthmic organizer at the mid/hindbrain junction; however, the underlying mechanism is unclear. We show that deleting Ptpn11, which links FGF with the ERK pathway, prevents inferior colliculus formation by depleting a previously uncharacterized stem cell zone. The stem-zone loss is attributed to shortening of S phase and acceleration of cell cycle exit and neurogenesis. Expression of a constitutively active Mek1 (Mek1DD), the known ERK activator, restores the tectal stem zone and the inferior colliculus without Ptpn11. By contrast, Mek1DD expression fails to rescue the tectal stem zone and the inferior colliculus in the absence of Fgf8 and the isthmic organizer, indicating that FGF and Mek1DD initiate qualitatively and/or quantitatively distinctive signaling. Together, our data show that the formation of the inferior colliculus relies on the provision of new cells from the tectal stem zone. Furthermore, distinctive ERK signaling mediates Fgf8 in the control of cell survival, tissue polarity and cytogenetic gradient during the development of the tectum.

Placental and cord blood brain derived neurotrophic factor levels are decreased in nondiabetic macrosomia.

PURPOSE: To measure levels of placental brain derived neurotrophic factor (BDNF) gene expression and umbilical cord blood BDNF in neonates with nondiabetic macrosomia and determine associations between these levels and macrosomia. METHODS: This case-control study included 58 nondiabetic macrosomic and 59 normal birth weight mother-infant pairs. Data were collected from interviews and our hospital's database. BDNF gene expression was quantified in placental tissues using quantitative real-time polymerase chain reaction (n = 117). Umbilical cord blood BDNF levels were measured by enzyme-linked immunosorbent assay (n = 90). Multivariate logistic regression models were used to evaluate associations between BDNF levels and macrosomia. RESULTS: Placental BDNF gene expression (P = 0.026) and cord blood BDNF (P = 0.008) were lower in neonates with nondiabetic macrosomia than in normal birth weight controls. Cord blood BDNF was significantly lower in vaginally delivered macrosomic neonates than vaginally delivered controls (P = 0.014), but cord BDNF did not differ between vaginal and cesarean section delivery modes in macrosomic neonates. Cord blood BDNF was positively associated with gestational age in control neonates (r = 0.496, P < 0.001), but not in macrosomic neonates. Cord blood BDNF was positively associated with placental BDNF relative expression (r s = 0.245, P = 0.02) in the total group. Higher cord blood BDNF levels were independently associated with protection against nondiabetic macrosomia (adjusted odds ratio 0.992; 95% confidence interval 0.986-0.998). CONCLUSIONS: Both placental BDNF gene expression and cord blood BDNF were downregulated in neonates with nondiabetic macrosomia compared with normal birth weight neonates. Cord BDNF may partly derive from BDNF secreted by the placenta. Higher cord plasma BDNF levels protected against nondiabetic macrosomia.

LCD-based digital eyeglass for modulating spatial-angular information.

Using programmable aperture to modulate spatial-angular information of light field is well-known in computational photography and microscopy. Inspired by this concept, we report a digital eyeglass design that adaptively modulates light field entering human eyes. The main hardware includes a transparent liquid crystal display (LCD) and a mini-camera. The device analyzes the spatial-angular information of the camera image in real time and subsequently sends a command to form a certain pattern on the LCD. We show that, the eyeglass prototype can adaptively reduce light transmission from bright sources by ~80% and retain transparency to other dim objects meanwhile. One application of the reported device is to reduce discomforting glare caused by vehicle headlamps. To this end, we report the preliminary result of using the reported device in a road test. The reported device may also find applications in military operations (sniper scope), laser counter measure, STEM education, and enhancing visual contrast for visually impaired patients and elderly people with low vision.

Liquid drop runs upward between two nonparallel plates.

We have recently observed an interesting phenomenon: even under gravity, a microliter-scaled silicone oil drop was still able to run upward between two nonparallel plates that were approximately vertically placed. We also saw the same phenomenon in the case of isopropyl alcohol (IPA) drops. In this work, we developed simple models to interpret this phenomenon, followed by experimental validation. We demonstrated that, by changing the locations of drops or tilt and opening angles of plates, the moving directions of silicone oil, IPA, and water drops could be controlled. In the cases of silicone oil and IPA, we also found that the speed of a drop had a linear relation with the square of the drop location when the drop was far away from the corner of two nonparallel plates and that the drop moved faster as it became closer to this corner.

Separation of oil from a water/oil mixed drop using two nonparallel plates.

In this work, we have developed a simple approach to separate oil from a microliter-scaled water/oil mixture by squeezing the mixture using two nonparallel plates. Three pairs of plates with Teflon, SU-8, and SiO2 coatings, respectively, are used in the tests, and all of these plates are capable of separating the water/oil mixed drops. 95.5% silicone oil and 97.0% light mineral oil have been collected from their corresponding mixtures with water through the pair of Teflon plates. Furthermore, on the basis of pressure difference inside a liquid drop, theoretical models have been developed to interpret the corresponding mechanisms of the separation process, as well as the observed phenomena. To judge whether two immiscible liquids could be separated using the developed approach, a sufficient condition has also been derived, which includes three theoretical relations. The sufficient condition is subsequently validated by experiments. This condition also provides criteria for choosing a good plate coating. Such a coating should ensure (i) the oil wets the plate surface with a relatively large contact angle, and has small contact angle hysteresis, and (ii) the advancing contact angle that the water/oil interface forms on the plate surface is larger than 90°.

Behavior of a liquid drop between two nonparallel plates.

Liquid drops have shown interesting behaviors between two nonparallel plates. These plates may be fixed or movable relative to each other. In this work, we also explore these behaviors through a combination of theoretical and experimental investigations and obtain some new results. We show that when the two plates are fixed, different from the previous understanding, a lyophilic drop may not necessarily fill the corner of the two plates. We also demonstrate that it may fill the corner, when more liquid is added to the drop or when the top plate is lifted. Furthermore, we propose a physical model to interpret the shifting effect of a liquid drop. This effect appears when the drop is squeezed and relaxed between two nonparallel plates, and it has been used by some shorebirds to transport prey. On the basis of the proposed model, we have found three new phenomena related to the shifting effect.

[Mechanism of biological actions of quercetin based on biomolecular network].

The mechanism of biological actions of quercetin was studied by using metabolomic method and biomolecular network. HPLC-MS was used to analyze the serum metabolome in rats of blank group and quercetin administration group rats, and MS data were processed by MATLAB software. With multivariate statistical analysis of serum metabolite profiles, a clear separation among blank group and quercetin administration group was achieved, potential biomarkers were selected according to the parameters of variable importance in the projection (VIP) and identified according to MS information and database retrieval. Four compounds, related enzymes, action targets and metabolic pathways had been confirmed, namely retinoic acid and RARbeta, arachidonate and COX-2, 3, 5-diodotyrosine and TPO, uridine diphosphate glucose and PDEs. The mechanism of quercetin enhancing ability of retinoic acid on the induction of RARbeta, activating TPO, using as COX-2 and PDEs inhibitor was approved by biomolecular network and related literatures. In this study, a mechanism of multiple biological actions of quercetin was evaluated at the level of the biomolecular network, metabolomics and biomolecular network can be used to investigate the biological effects mechanism of quercetin, which provided a new method to further revealing mechanism of drug action.

BCL6B-dependent suppression of ETV2 hampers endothelial cell differentiation.

BACKGROUND: B-cell CLL/lymphoma 6 member B (BCL6B) operates as a sequence-specific transcriptional repressor within the nucleus, playing crucial roles in various biological functions, including tumor suppression, immune response, stem cell self-renew, and vascular angiogenesis. However, whether BCL6B is involved in endothelial cell (EC) development has remained largely unknown. ETS variant transcription factor 2 (ETV2) is well known to facilitate EC differentiation. This study aims to determine the important role of BCL6B in EC differentiation and its potential mechanisms. METHODS: Doxycycline-inducible human induced pluripotent stem cell (hiPSC) lines with BCL6B overexpression or BCL6B knockdown were established and subjected to differentiate into ECs and vessel organoids (VOs). RNA sequencing analysis was performed to identify potential signal pathways regulated by BCL6B during EC differentiation from hiPSCs. Quantitative real-time PCR (qRT-PCR) was used to detect the expression of pluripotency and vascular-specific marker genes expression. EC differentiation efficiency was determined by Flow cytometry analysis. The performance of EC was evaluated by in vitro Tube formation assay. The protein expression and the vessel-like structures were assessed using immunofluorescence analysis or western blot. Luciferase reporter gene assay and chromatin immunoprecipitation (ChIP)-PCR analysis were used to determine the regulatory relationship between BCL6B and ETV2. RESULTS: Functional ECs and VOs were successfully generated from hiPSCs. Notably, overexpression of BCL6B suppressed while knockdown of BCL6B improved EC differentiation from hiPSCs. Additionally, the overexpression of BCL6B attenuated the capacity of derived hiPSC-ECs to form a tubular structure. Furthermore, compared to the control VOs, BCL6B overexpression repressed the growth of VOs, whereas BCL6B knockdown had little effect on the size of VOs. RNA sequencing analysis confirmed that our differentiation protocol induced landscape changes for cell/tissue/system developmental process, particularly vascular development and tube morphogenesis, which were significantly modulated by BCL6B. Subsequent experiments confirmed the inhibitory effect of BCL6B is facilitated by the binding of BCL6B to the promoter region of ETV2, led to the suppression of ETV2's transcriptional activity. Importantly, the inhibitory effect of BCL6B overexpression on EC differentiation from hiPSCs could be rescued by ETV2 overexpression. CONCLUSIONS: BCL6B inhibits EC differentiation and hinders VO development by repressing the transcriptional activity of ETV2.

MDIVI-1 ALLEVIATES SEPSIS-INDUCED LIVER INJURY BY INHIBITING STING SIGNALING ACTIVATION.

ABSTRACT: Proinflammatory hyperactivation of Kupffer cells (KCs) is foremost involved in the pathogenesis of sepsis-induced liver injury. Our previous study found that stimulator of interferon genes (STING) signaling was activated in KCs in response of lipopolysaccharide (LPS) and knocking down dynamin-related protein 1 (DRP1) in KCs effectively inhibited the activation of STING signaling and the subsequent production of proinflammatory cytokines. In this study, we demonstrated that in vivo treatment with mitochondrial division inhibitor 1 (Mdivi-1), a selective inhibitor of DRP1, alleviated cecal ligation and puncture (CLP)-induced liver injury with the improvement of liver pathology and function. Moreover, we found that STING in liver was mainly concentrated in KCs and STING signaling was significantly activated in KCs after CLP. The STING deficiency effectively ameliorated liver injury and decreased the mortality of septic mice, which were reversely worsened by the enhanced activation of STING with DMXAA. The further study showed that Mdivi-1 markedly attenuated STING signaling activation in KCs and inhibited systemic inflammatory response. Importantly, DMXAA application in CLP mice blunted Mdivi-1's liver protection effect. Taken together, our study confirmed Mdivi-1 effectively alleviated CLP-induced liver injury partially through inhibiting STING signaling activation in KCs, which provides new insights and a novel potential pharmacological therapeutic target for treating septic liver injury.

The value of sequential application of hydrogen peroxide, povidone-iodine and physiological saline in reducing postoperative infections after total knee arthroplasty: A prospective, randomized, controlled study.

BACKGROUND: Currently, in the field of total joint arthroplasty (TJA), there are no studies that have demonstrated the value of the sequential application of hydrogen peroxide, povidone-iodine, and physiological saline during the surgical procedure in decreasing postoperative infections in total knee arthroplasty (TKA), and in decreasing the incidence of periprosthetic joint infections (PJI) in particular. This study aimed to assess the efficacy of the sequential application of hydrogen peroxide, povidone-iodine, and physiological saline in reducing postoperative infections in TKA. METHODS: The study prospectively included 4743 patients, with Group A (2371, 49.9%) receiving sequential intraoperative application of hydrogen peroxide, povidone-iodine, and physiological saline irrigation of the incision, and Group B (2372, 50.1%) receiving intraoperative application of physiological saline irrigation of the incision only, to collect the patients' baseline data and clinical characteristics, and to statistically assess the incidence of superficial infections and the PJI during the follow up period to evaluate the clinical value of the study. RESULTS: The baseline levels of patients in Groups A and B were comparable. There were 132 (2.8%) lost visits during the study period. The incidence of superficial infections within 30 days after surgery was 0.22% in Group A and 1.17% in Group B, the difference between the two groups was statistically significant (P = 0.007). The incidence of PJI was 0.17% in Group A and 1.26% in Group B, the difference between the two groups was statistically significant (P = 0.0121). CONCLUSION: Sequential application of hydrogen peroxide, povidone-iodine, and physiological saline to irrigate incision in TKA can significantly reduce the incidence of postoperative superficial infections and PJI. The scientific and rational application of this therapy intraoperatively greatly reduces the incidence of PJI and postoperative superficial infections, which is of great benefit to the patient's prognosis.

L-Cysteine: A promising nutritional supplement for alleviating anxiety disorders.

Anxiety disorders are prevalent chronic psychological disease with complex pathogenic mechanisms. Current anxiolytics have limited efficacy and numerous side effects in many anxiety patients, highlighting the urgent need for new therapies. Recent research has been focusing on nutritional supplements, particularly amino acids, as potential therapies for anxiety disorders. Among these, L-Cysteine plays a crucial role in various biological processes. L-Cysteine exhibits antioxidant properties that can enhance the antioxidant functions of the central nervous system (CNS). Furthermore, metabolites of L-cysteine, such as glutathione and hydrogen sulfide have been shown to alleviate anxiety through distinct molecular mechanisms. Long-term administration of L-Cysteine has anxiolytic, antidepressant, and memory-improving effects. L-Cysteine depletion can lead to increased oxidative stress in the brain. This review delves into the potential mechanisms of L-Cysteine and its main products, glutathione (GSH) and hydrogen sulfide (H2S) in the management of anxiety and related diseases.

Comparison of nomogram for Primary Nonfunctional Pancreatic Neuroendocrine Tumors based on the 7th vs 8th edition of the AJCC cancer staging manual.

BACKGROUND: Our study aimed to construct and validate prognostic nomograms for predicting survival for patients with Nonfunctional Pancreatic neuroendocrine tumor (NF-pNET). METHODS: This retrospective study included 1824 patients diagnosed with NF-pNET in the Surveillance, Epidemiology and End Results database between 2004 and 2016. Randomization divided the patients into training (n = 1278) and validation (n = 546) cohorts. Prognostic factors were determined using Cox regression analyses, nomograms based on AJCC 7th and 8th staging system were constructed separately. The prediction models were validated using internal validation and external validation. RESULTS: Age, year of diagnosis, primary tumor site, grade, 7th or 8th TNM stage, surgery, tumor size were determined as prognostic indicator to construct two nomograms. Harrell's concordance index (C-index) of two nomograms exhibited a clinical predictive ability of 0.828 (95%CI, 0.808~0.849) vs 0.828 (95% CI, 0.808~0.849) in the internal verification. The c-index in the external validation was 0.812 (95%CI, 0.778~0.864) vs 0.814 (95% CI, 0.779~0.848). The predictive power of the two nomograms is comparable. CONCLUSIONS: Our nomogram may be a effective tool for predicting overall survival in patients with NF-pNET. The AJCC 8th-edition system provides discrimination similar to that of the 7th-edition system.

The complete mitochondrial genome of Hyotissasinensis (Bivalvia, Ostreoidea) indicates the genetic diversity within Gryphaeidae.

Different from the true oyster (family Ostreidae), the molecular diversity of the gryphaeid oyster (family Gryphaeidae) has never been sufficiently investigated. In the present study, the complete mitochondrial (mt) genome of Hyotissasinensis was sequenced and compared with those of other ostreoids. The total length of H.sinensis mtDNA is 30,385 bp, encoding 12 protein-coding-genes (PCGs), 26 transfer RNA (tRNA) genes and two ribosomal RNA (rRNA) genes. The nucleotide composition and codon usage preference of H.sinensis mtDNA is similar to that of H.hyotis within the same genus. On the other hand, the presence of three trnM and three trnL genes of H.sinensis was not detected neither in H.hyotis nor other ostroid species. Another unique character of H.sinensis mtDNA is that both rrnS and rrnL have a nearly identical duplication. The PCG order of H.sinensis is identical to H.hyotis and the two congener species also share an identical block of 12 tRNA genes. The tRNA rearrangements mostly happen in the region from Cox1 to Nad3, the same area where the duplicated genes are located. The rearrangements within Gryphaeidae could be explained by a "repeat-random loss model". Phylogenetic analyses revealed Gryphaeidae formed by H.sinensis + H.hyotis as sister to Ostreidae, whereas the phylogenetic relationship within the latter group remains unresolved. The present study indicated the mitogenomic diversity within Gryphaeidae and could also provide important data for future better understanding the gene order rearrangements within superfamily Ostreoidea.

Single-cell RNA sequencing reveals the immune microenvironment and signaling networks in cystitis glandularis.

Introduction: Cystitis glandularis (CG) is a rare chronic bladder hyperplastic disease that mainly manifests by recurrent frequent urination, dysuria and gross hematuria. The current lack of unified diagnosis and treatment criteria makes it essential to comprehensively describe the inflammatory immune environment in CG research. Methods: Here, we performed scRNA-sequencing in CG patients for the first time, in which four inflamed tissues as well as three surrounding normal bladder mucosa tissues were included. Specifically, we isolated 18,869 cells to conduct bioinformatic analysis and performed immunofluorescence experiments. Results: Our genetic results demonstrate that CG does not have the classic chromosomal variation observed in bladder tumors, reveal the specific effects of TNF in KRT15 epithelial cells, and identify a new population of PIGR epithelial cells with high immunogenicity. In addition, we confirmed the activation difference of various kinds of T cells during chronic bladder inflammation and discovered a new group of CD27-Switch memory B cells expressing a variety of immunoglobulins. Discussion: CG was regarded as a rare disease and its basic study is still weak.Our study reveals, for the first time, the different kinds of cell subgroups in CG and provides the necessary basis for the clinical treatment of cystitis glandularis. Besides, our study significantly advances the research on cystitis glandularis at the cellular level and provides a theoretical basis for the future treatment of cystitis glandularis.

Bibliometric and visualized analysis of applying tumor markers in lung cancer diagnosis from 2000 to 2022.

Background: Lung cancer (LC) is the leading cause of cancer-related deaths worldwide. Tumor marker (TM) detection can indicate the existence and growth of a tumor and has therefore been used extensively for diagnosing LC. Here, we conducted a bibliometric analysis to examine TM-related publications for LC diagnosis to illustrate the current state and future trends of this field, as well as to identify additional promising TMs with high sensitivity. Methods: Publications regarding TMs in LC diagnosis were downloaded from the Web of Science Core Collection. CiteSpace was applied to perform a bibliometric analysis of journals, cocitation authors, keywords, and references related to this field. VOSviewer was used to generate concise diagrams about countries, institutions, authors, and keywords. Changes in the TM research frontier were analyzed through citation burst detection. Results: A total of 990 studies were analyzed in this work. The collaboration network analysis revealed that the People's Republic of China, Yonsei University, and Molina R were the most productive country, institution, and scholar, respectively. Additionally, Molina R was the author with the most citations. The National Natural Science Foundation of China was the largest funding source. "Carcinoembryonic antigen (CEA) as tumor marker in lung cancer" was the top reference with the most citations, Lung Cancer was the core journal, and "serum tumor marker" experienced a citation burst over the past 5 years. Conclusion: This bibliometric analysis of TMs in LC diagnosis presents the current trends and frontiers in this field. We summarized the research status of this field and the methods to improve the diagnostic efficacy of traditional serum TMs, as well as provided new directions and ideas for improving the LC clinical detection rate. Priority should be given to the transformation of computer-assisted diagnostic technology for clinical applications. In addition, circulating tumor cells, exosomes, and microRNAs were the current most cutting-edge TMs.

A stable intermediate wetting state after a water drop contacts the bottom of a microchannel or is placed on a single corner.

It is considered that, after a water drop contacts the base of a roughness groove, water should immediately fill this roughness groove. Subsequently, Cassie-Baxter wetting state is transited to that of Wenzel. Accordingly, one of the criteria used to judge the transition from Cassie-Baxter to Wenzel states is whether a water drop has contact with the base of a roughness groove. In this work, through theoretical and experimental investigations, we show that this transition criterion does not always hold true in the case of microchannels. We first theoretically prove that, when an angle criterion is satisfied, there may exist an intermediate wetting state inside a microchannel after a water drop contacts the bottom of the microchannel. In this wetting state, water does not completely fill the microchannel, and air pockets still exist in its bottom corners. Also, the wetting state is stable in the sense that its energy state is lower than that of the Wenzel model. According to the angle criterion, such intermediate states may exist, for example, in microchannels with vertical sidewalls, when contact angles on the inner surfaces of these microchannels are larger than 135°. In addition to microchannels, the aforementioned intermediate state may also exist on a single corner (which is formed by a horizontal plate and an inclined plate), when the angle criterion is met. After theoretical modeling, we then conduct four types of tests on single corners and microchannels to validate the angle criterion. In these tests, once the angle criterion is met, stable intermediate states are observed on the corresponding samples. In addition, it is found from the two types of tests conducted on microchannels that, once Laplace pressure inside a water drop is gradually reduced, such an intermediate wetting state may be transited back to the original Cassie-Baxter state. On the other hand, the Wenzel state may not have such a reversal transition unless an additional force is applied to overcome energy barrier between Wenzel and Cassie-Baxter states.

Effect of prior thyroid cancer on survival of primary liver cancer: a study based on the SEER database.

To explore the effect of prior thyroid cancer on the survival of primary liver cancer (PLC). Eligible PLC patients were selected from the Surveillance, Epidemiology, and End Results (SEER) database during 2004-2016. Propensity score matching (PSM) was used to create a highly comparable control group that PLC patients without prior thyroid cancer. All PLC patients were divided into three groups based on the survival information: (1) PLC-specific death; (2) death due to other causes; (3) alive. The effect sizes were presented by the corresponding hazard ratio (HR) and 95% confidence intervals (CI). Totally, 142 PLC patients with prior thyroid cancer and 1420 PLC patients without prior thyroid cancer were included. During the follow-up period, 714 (45.71%) PLC patients died of liver cancer while 638 (40.85%) PLC patients were alive. Median survival time for PLC patients was 11.00 months, respectively. PLC patients with prior thyroid cancer have a lower risk of death (HR = 0.64; 95% CI: 0.48-0.86). Subgroup analyses stratified by gender displayed the similar relation in female patients with PLC. Prior thyroid cancer may be a protective factor for liver cancer death in PLC patients, especially in female patients.
