Abstract
Objective: To assess the effectiveness and safety of adalimumab in Crohn's disease (CD) patients. Methods: We retrospectively reviewed the charts of 41 CD patients who received adalimumab in Zhongda Hospital Southeast University from January 2020 to August 2021. General clinical data, laboratory results, endoscopy and radiologic findings were collected, meanwhile, disease activity and safety events were evaluated at baseline and at 12, 24 and 48 weeks of administration. Adalimumab was given subcutaneously once every 2 weeks in doses of 160 mg for the first time, 80 mg for the second time, and 40 mg for each subsequent time. Results: The clinical remission rates at 12, 24, and 48 weeks of treatment were 43.9% (18/41), 60.6% (20/33), 60.9% (14/23), and the clinical response rates were 75.6% (31/41), 69.7% (23/33), and 56.5%( 13/23), respectively. The proportion of endoscopic remission at 12, 24 and 48 weeks were 4/14, 2/6, 1/4 in patients undergoing endoscopy, and 1/14 patients achieved mucosal healing at 24 weeks. Primary nonresponse rate (PNR) was 17.1% (7/41), loss of response (LOR) rate was 14.6% (6/41). The incidence of adverse reactions was 9.8%(4/41). Conclusion: Adalimumab can effectively relieve the clinical symptoms and intestinal disease activities of Crohn's disease, and deserves to be popularized clinically. Patients with disease course <2 years, first-line biologics, low baseline HBI score, and longer duration of medication may have better results.

The burden of end-stage osteoarthritis in Australia: a population-based study on the incidence of total knee replacement attributable to overweight/obesity. Osteoarthritis Cartilage 2022; 30:1254-1262. [PMID: 34890810 DOI: 10.1016/j.joca.2021.10.017] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/11/2021] [Revised: 10/11/2021] [Accepted: 10/27/2021] [Indexed: 02/02/2023]
Abstract
OBJECTIVES To determine the risk of total knee replacement (TKR) for primary osteoarthritis (OA) associated with overweight/obesity in the Australian population. METHODS This population-based study analyzed 191,723 cases of TKR collected by the Australian Orthopaedic Association National Joint Registry and population data from the Australian Bureau of Statistics. The time-trend change in incidence of TKR relating to BMI was assessed between 2015 and 2018. The influence of obesity on the incidence of TKR in different age and gender groups was determined. The population attributable fraction (PAF) was then calculated to estimate the effect of obesity reduction on TKR incidence. RESULTS The greatest increase in incidence of TKR was seen in patients from obese class III. The incidence rate ratio for having a TKR for obesity class III was 28.683 at those aged 18-54 years but was 2.029 at those aged >75 years. Females in obesity class III were 1.7 times more likely to undergo TKR compared to similarly classified males. The PAFs of TKR associated with overweight or obesity was 35%, estimating 14,287 cases of TKR attributable to obesity in 2018. The proportion of TKRs could be reduced by 20% if overweight and obese population move down one category. CONCLUSIONS Obesity has resulted in a significant increase in the incidence of TKR in the youngest population in Australia. The impact of obesity is greatest in the young and the female population. Effective strategies to reduce the national obese population could potentially reduce 35% of the TKR, with over 10,000 cases being avoided.

Abstract
Objective: To analyze the literature published in Chinese Journal of Burns (now Chinese Journal of Burns and Wounds) in the last 22 years, and to explore the development trend of burn discipline. Methods: The relevant clinical and research literature published in Chinese Journal of Burns from January 1, 2000 to December 31, 2021 were retrieved through China National Knowledge Infrastructure database. Bibliometrics was used to classify and analyze the literature by research types, involved research fields, and reported causes of injury, and compare them every 3 years according to the year of publication (with literature published in 2021 being included in the last time period). Keywords of all the literature were retrieved, which were corrected and conversed later. CiteSpace 6.1.R2 software was used to visually cluster the included keywords, count high-frequency and high-centrality keywords, and divide the high-frequency keywords by time as before for segment comparison. Results: A total of 4 485 relevant papers were included, with an average of about 204 papers each year. The research types analysis of literature showed that clinical diagnosis and treatment literature had the highest proportion, reaching 65.3% (2 929/4 485), followed by cell experiment and animal experiment literature, accounting for 18.1% (812/4 485) and 13.2% (591/4 485), respectively. The proportion of various research types of the literature in each time period was basically stable. The analysis of the research fields involved in the literature showed that the literature in the field of systemic treatment of burns accounted for the highest proportion, reaching 60.2% (2 699/4 485), followed by the literature in the fields of acute wounds and plastic surgery, accounting for 20.2% (908/4 485) and 7.3% (326/4 485), respectively. The proportion of the literature in the field of systemic treatment of burns decreased from 84.0% (430/512) in 2000-2002 to 40.3% (373/926) in 2018-2021, with a decreasing proportion of 43.7%. While compared with that in 2000-2002, the proportions of literature in the fields of acute wounds, plastic surgery, chronic wounds, and burn rehabilitation were on the rise, with the proportions in 2018-2021 increased by 11.7%, 9.1%, 10.7%, and 5.5%, respectively. In the first 6 time periods, the number of literature in the field of discipline management was few and remained in single digits, but it increased to 49 in 2018-2021. Among the 1 099 literature in the field of systemic treatment of burns with a clear cause of injury, the literature on thermal burns was the most, accounting for 58.5% (643/1 099), followed by the literature on electrical burns and chemical burns, accounting for 19.8% (218/1 099) and 12.6% (138/1 099), respectively. The comparison by time period showed that the proportion of literature reporting thermal burns showed a significant downward trend, while the proportion of literature reporting other causes of injury did not change significantly. A total of 6 822 keywords from 2 236 literature were included for analysis. Visual cluster analysis showed that relevant studies focused on burns, surgical flaps, scars, and wound healing. The top 3 keywords in frequency were burns, wound healing, and surgical flaps, and the top 3 keywords in centrality were burns, scars, and skin transplantation. The comparison by time period showed that the only keyword with a stable frequency in the top 10 ranks was burns; with the passage of time, some keywords such as endotoxin/endotoxins and fibroblasts gradually dropped out of the top 10 ranks, while keywords such as wounds and injuries, surgical flaps, and negative-pressure wound therapy gradually entered the top 10 ranks. Conclusions: Among the literature published in Chinese Journal of Burns during the last 22 years, the literature on systemic treatment of burns and thermal burns has gradually decreased, while the literature on chronic wounds and burn rehabilitation has increased. Surgical flaps, wound healing, and scar prevention and treatment are the current research hot spots in burn discipline.

Abstract
The incidence and mortality of HCC in China account for approximately 50% of all cases worldwide. Low early diagnosis rate and high postoperative recurrence rate are two major causes for poor 5-year survival rate of HCC patients in China. At present, multiple problems such as low performance and compliance of screening technology and lack of effective markers for predicting postoperative recurrence, remain to be resolved. Due to the simplicity and accuracy, new molecular markers, such as liquid biopsy, are expected to serve as supplementary tools to traditional screening and early warning approaches, thereby realizing early detection and accurate treatment of HCC. In this article, research progress upon the clinical application of liquid biopsy in early screening and prediction of postoperative recurrence of HCC was reviewed, and prospects the future research.

Abstract
OBJECTIVE To explore the expression of fibronectin type Ⅲ domain containing 1(FNDC1) protein in lung adenocarcinoma and its prognostic significance. METHODS The expression of FNDC1 in lung adenocarcinoma was predicted by analysis of data from GEO database and GEPIA, and the results were verified by immunohistochemical staining in 92 pairs of clinical specimens of lung adenocarcinoma and adjacent tissues.We further analyzed the correlation of FNDC1 expression with the clinicopathological features of the patients, and evaluated its prognostic value using Cox survival analysis. RESULTS Analysis of the data form GEO database and GEPIA showed a significantly higher expression level of FNDC1 in lung adenocarcinoma than in matched normal tissues (P < 0.05).Kaplan-Meier survival analysis suggested that a high expression of FNDC1 protein was associated with a significantly shorter overall survival time of the patients (P < 0.05).Immunohistochemistry of the clinical specimens also showed a significantly higher protein expression of FNDC1 in lung adenocarcinoma tissues than in paired adjacent tissues (P < 0.001).A high expression of FNDC1 protein was significantly correlated with advanced clinical stage, T stage and N stage (P < 0.05).Cox univariate and multivariate regression survival analysis indicated that an increased expression of FNDC1 was an independent risk factor for poor prognosis of the patients with lung adenocarcinoma (P < 0.05). CONCLUSION FNDC1 protein is highly expressed in patients with lung adenocarcinoma and in closely related with the occurrence, progression and prognosis of the tumor, suggesting the value of FNDC1 protein as a potential biomarker for assessment of the survival and prognosis of patients with lung adenocarcinoma.

Abstract
Ductal origin of distal pulmonary artery (DODPA) is a rare congenital cardiovascular anomaly, with an incidence of approximately 1 in 200 000 people. It involves the proximal interruption of one pulmonary artery branch, with the distal part arising from the base of the brachiocephalic artery, via the ipsilateral ductus arteriosus (DA) and the intrapulmonary branch of the pulmonary artery is usually intact. If timely treatment is not provided after birth, it is very likely that, due to DA closure, severe hypoplasia will occur in the lung supplied by the abnormal pulmonary artery. Hence, prenatal diagnosis of DODPA is important to enable initiation of prostaglandin treatment and early rehabilitation of the affected lung. Herein, we report three cases of fetal DODPA diagnosed via two-dimensional (2D) ultrasonography combined with four-dimensional (4D) spatiotemporal image correlation. We also present a literature review, and explore the ultrasonographic findings and the importance of 2D and 4D ultrasonography in obtaining an accurate prenatal diagnosis of DODPA. © 2021 International Society of Ultrasound in Obstetrics and Gynecology.

Abstract
The inferior cycling performance caused by large volume variation is the main problem that restricts the application of cobalt selenides in lithium-ion batteries. Herein, we synthesize raspberry-like Co-ethylene glycol precursor. It is further selenized into the hierarchical hollow superstructure CoSe2/CoSe bird nests that are assembled by the hollow nanosphere units of CoSe2 and CoSe nanocrystalline. CoSe2/CoSe bird nests achieve excellent cycling performance, high reversible capacity and satisfactory rate capability (1361 mAh/g at 1 A/g after 1000 cycles, 579 mAh/g at 2 A/g after 2000 cycles, 315 mAh/g at 5 A/g after 1000 cycles). Electrochemical kinetics analyses and ex-situ material characterization reveal that the surface capacitive behavior controls the electrochemical reaction, and the composite has low reaction impedance, fast and stable Li+ diffusion, and superior structural stability. The superior lithium storage performance is attributed to the unique superstructure bird nest. Large specific surface area, abundant hierarchical pores and the opening mouth result in high electrochemical activity, which induces high reversible capacity. The small hollow nanosphere units, the sufficiently thick hierarchical porous superstructure shell and the large hollow interior bring about the strong synergistic effect to improve cycling performance. The intimately coupling of CoSe2/CoSe nanocrystalline and the hollow nanosphere units guarantees high conductivity. This work has greatly enriched the understanding of structure design of high-performance cobalt selenide anodes.

Abstract
Alpha power attenuation during cognitive task performing has been suggested to reflect a process of release of inhibition, increase of excitability, and thereby benefit the improvement of performance. Here, we hypothesized that changes in individual alpha power during the execution of a complex language comprehension task may correlate with the individual performance in that task. We tested this using magnetoencephalography (MEG) recorded during comprehension of German sentences of different syntactic complexity. Results showed that neither the frequency nor the power of the spontaneous oscillatory activity at rest were associated with the individual performance. However, during the execution of a sentences processing task, the individual alpha power attenuation did correlate with individual language comprehension performance. Source reconstruction localized these effects in left temporal-parietal brain regions known to be associated with language processing and their right-hemisphere homologues. Our results support the notion that in-task attenuation of individual alpha power is related to the essential mechanisms of the underlying cognitive processes, rather than merely to general phenomena like attention or vigilance.

Abstract
Objective: To explore the association of lifestyle and cardiometabolic risk factors with five epigenetic age acceleration (AA) indices. Methods: This study included 980 participants of China Kadoorie Biobank, for whom genome-wide DNA methylation of peripheral blood cells had been detected in baseline survey. Five indices of DNA methylation age (DNAm age) were calculated, i.e. Horvath clock, Hannum clock, DNAm PhenoAge, GrimAge and Li clock. Epigenetic AA was defined as the residual of regressing DNAm age on chronological age. Lifestyle factors studied included smoking status, alcohol consumption, eating habits, physical activity level and body shape defined by a combination of BMI and waist circumference. Cardiometabolic risk factors included blood pressure, blood glucose level and total cholesterol level. Linear regression model was used to analyze the association of lifestyle and cardiometabolic risk factors with AA (β). Results: GrimAge_AA was associated with smoking status, alcohol consumption, physical activity level and BMI. Compared with non-smokers, non-drinkers, or participants with BMI of 18.5- 23.9 kg/m2, the smokers who smoked 1-14 cigarettes/day (β=0.71, 95%CI: 0.57-0.86), 15-24 cigarettes/day (β=0.88, 95%CI: 0.73-1.03), and ≥25 cigarettes/day (β=0.99, 95%CI: 0.81-1.18), respectively, heavy drinkers with daily pure alcohol consumption ≥60 g (β=0.33, 95%CI: 0.11-0.55) and participants with BMI<18.5 kg/m2 (β=0.23, 95%CI: 0.03-0.43) showed accelerated aging. Compared with those in the lowest quintile of physical activity level, participants in the top three quintile of physical activity level showed decelerated aging (β=-0.13, 95%CI: -0.26-0.01, β=-0.12, 95%CI: -0.26-0.02, and β=-0.14, 95%CI: -0.27- -0.00, respectively). GrimAge_AA decreased with the increase of the number of healthy lifestyle factors (P<0.001). Compared with the participants with 0 to 1 healthy lifestyle factor, the β of those with 2, 3, or 4 to 5 healthy lifestyle factors were -0.30 (95%CI: -0.47- -0.12), -0.47 (95%CI: -0.65- -0.30) and -0.72 (95%CI: -0.90- -0.53), respectively. The other four indices were not statistically significantly associated with most lifestyle factors. None of the five indices of AA was associated with blood pressure, blood glucose level or total cholesterol level. Conclusion: People with unhealthy lifestyle showed accelerated epigenetic aging, that is, the predicted DNAm age is older than their own chronological age.

Abstract
Objective: We aimed to assess the effects of outdoor time in preventing incident myopia among primary school students and evaluate its differences among different grades to provide evidence for policy formulation related to myopia prevention. Methods: This study is a cohort study. We investigated 6 046 grade 1 to 5 students in 9 provinces, Jiangsu, Shanghai, Fujian, Shanxi, Henan, Hunan, Gansu, Chongqing, and Guangxi. In 2019, we measured their myopia on site. In 2020, we did a follow-up visit on those students to detect the myopia incidence rate. Information regarding outdoor time and myopia-related behaviors were obtained from a questionnaire within one week of visual acuity measurement in 2020. The chi-square test and Cochran-Armitage trend test compared the differences between groups. The Cox proportional hazards risk model was used to test the relationship between outdoor time and myopia. Results: In 2020, the overall myopia incidence rate of grade 1 to 5 students in the baseline was 27.5%; while 23.0% in grades 1 and 2 students and 31.7% in grades 3 to 5 students, respectively. After controlling for covariates, for students in grade 1 to 2, those with ≥1 hour of outdoor time per day were at 0.76 (95%CI: 0.62-0.93, P=0.008) times risk of being myopia than that of students with <1 hour of outdoor time per day; while for students in grades 3 to 5, an average of ≥3 hours of outdoor time per day was required to have a significant protective effect on myopia. The students with ≥3 hours of outdoor time per day were less likely to be myopia (OR=0.75, 95%CI: 0.61-0.93, P=0.007) than those students with <3 hours of outdoor time per day. Conclusions: For grade 1 and 2 students, 1 hour of outdoor time per day could reduce the incidence of myopia, whereas for grade 3 to 5 students, 3 hours of outdoor time per day could effectively reduce the incidence of myopia. Therefore, the recommendations for outdoor time as myopia prevention should be different for different grades. The higher the grade is, the more outdoor time should be spent to reduce myopia incidence. Moreover, other factors that affect myopia's incidence should be also paid attention to, and a comprehensive approach should be adopted to prevent and control the incidence of myopia.

Abstract
Objective: To analyze the clinical characteristics and influencing factors of children with parent-reported food allergy (FA), thus providing empirical evidence for facilitating the effective utilization of medical history information and promoting better health education for parents. Methods: A cross-sectional study was conducted, recruiting all 596 children under 3 years of age who underwent physical examinations from July to August 2019 at the Department of Child Health Care, Children's Hospital of Chongqing Medical University. Children were carried out with questionnaires, skin prick test, and diagnosed with FA through oral food challenge (OFC) by pediatricians. The parent-reported incidence rate, symptoms of FA, and the possible influencing factors, including demographic characteristics, family history of allergy, in-utero exposure to smoke and antibiotic use, feeding methods after birth, and residential environment were collected by questionnaire. The differences of clinical characteristics between parent-reported FA and medically diagnosed FA were analyzed by chi-square test. Logistic regression was used to analyze the factors associated with parent-reported FA. Results: A total of 596 children (316 boys and 280 girls) were recruited for this study. The incidence rate of FA by parent-report (22.0%, 131/596) was higher than that by medical diagnosis (9.9%, 59/596) (χ²=32.46, P<0.001). There were 36.6% (48/131) of children with parent-reported FA and 2.4% (11/465) of children without parent-reported FA receiving medical diagnosis of FA. Among children with parent-reported allergic symptoms, 37.5% (24/64) of those with gastrointestinal symptoms and 31.5% (23/73) of those with skin symptoms received medical diagnosis of FA, respectively. Six out of 7 children with co-presenting cutaneous and gastrointestinal symptoms were diagnosed with FA. Univariate Logistic regression analysis showed that family history of allergy (OR=1.83 (95%CI 1.22-2.73), P=0.003) and damp living environments (OR=2.33 (95%CI 1.13-4.79), P=0.022) were associated with higher likelihood of parent-reported FA. Conclusions: The incidence rate of parent-reported FA is higher than medically diagnosed FA. Clinicians should be highly suspicious of the possibility of FA in children with both cutaneous and gastrointestinal symptoms.

Abstract
PURPOSE Ghrelin, a gastric hormone, provides a hunger signal to the central nervous system to stimulate food intake. Ghrelin also modulates neuroinflammatory and apoptotic processes. Dedicator of cytokinesis 4 (DOCK4), a guanine nucleotide exchange factor (GEF), is involved in the regulation of neuronal polarization and axon regeneration. However, the effect of DOCK4 on ghrelin production has not been explored. METHODS The expression of DOCK4 in human and mouse stomach was examined by immunohistochemical staining. The synthesis and secretion of ghrelin in Dock4 null mice were evaluated by real-time quantitative PCR, Western blot and ELISA. The effects of DOCK4 on ghrelin production in mHypoE-42 cells were measured by real-time quantitative PCR and Western blot. RESULTS We showed that DOCK4 was expressed in both human and mouse gastric ghrelin cells. The mRNA and protein levels of gastric ghrelin, as well as ghrelin secretion, were remarkably diminished in Dock4 null mice. Furthermore, we showed that overexpression of Dock4 significantly stimulated ghrelin expression, while siRNA knockdown of endogenous Dock4 resulted in a marked decrease of ghrelin in mHypoE-N42 cells. CONCLUSIONS Our results identify DOCK4 as a critical regulator for ghrelin production in gastric X/A-like cells.

Abstract
Abstract
Study question
Intraabdominal hemorrhage is a rare but serious complication following (oocyte pick up, OPU), it is very important for clinicians to know the risk factors.
Summary answer
Intraabdominal hemorrhage is mild in most cases, laparoscopy or laparotomy is the most effective approach to stop bleeding quickly in severe intraabdominal hemorrhage cases.
What is known already
During the OPU procedure, intraabdominal hemorrhage is not visible without the assistance of ultrasound, even minor bleeding, if persists, may lead to life-threatening consequences. Previous publications had limited sample size and the analysis of serial cases was scarce, most studies focused on severe hemorrhage that necessitated surgical interventions and somehow neglected those with mild hemorrhage. The reported incidence of severe intraabdominal hemorrhage varied from 0.06% to 0.27%, while 0.08%-0.1% of patients required surgery.
Study design, size, duration
Retrospective study, 25 cases that underwent post-OPU intraabdominal hemorrhage and required hospitalization in our center since 2003 to January 2021.
Participants/materials, setting, methods
Patients underwent intraabdominal hemorrhage following OPU in a University-affiliated center needed to be hospitalized. We aimed to discuss the clinical characteristics, risk factors, and precautionary measures of intraabdominal hemorrhage following OPU procedures.
Main results and the role of chance
The incidence of intraabdominal hemorrhage following OPU procedures was 0.044%. In all 25 cases, 17 received conservative treatment while emergency surgical exploration was performed to stop bleeding quickly for the remaining patients. Primary symptoms included the following: abdominal distention and/or pain, chest distress, dizziness, syncope, tenesmus, palpitations, etc.48% and 92% of patients had obvious symptoms within the first hour and 12 hours following OPU, respectively. Pelvic hematoma and/or effusion were found under ultrasonic scan in all but three patients. Overall, the reduction in hemoglobin(ΔHb) and hematocrit (ΔHct) were 26.50±13.32 g/L and 7.70%±3.66%, respectively. The mean interval between OPU and surgical procedure was 29.88±18.80 hours. And the main intra-operative findings were laceration and/or active bleeding on the ovary and satisfied hemostasis was achieved through suture or electrocoagulation. The blood aspirated during the procedure was 1 563±548 ml on average. Before they got discharged, these patients stayed at hospital for 5.04 days on average. In addition, our data shows that intraabdominal hemorrhage following OPU does not affect the final pregnancy outcomes, the cumulative live birth rate per woman was 48% (12/25).
Limitations, reasons for caution
This study is limited by its retrospective nature. In addition, patients who underwent mild hemorrhage and received effective therapy in an outpatient clinic rather than hospitalization or elsewhere were not included, which might lead to underestimation of the incidence concerned.
Wider implications of the findings
Intraabdominal hemorrhage is a rare but serious complication following OPU, which might be life-threatening. Nonetheless, hemorrhage is mild in most cases and conservative treatment is the first-line choice. Laparoscopy or laparotomy is the most effective approach to stop bleeding quickly in severe intraabdominal hemorrhage cases.

Abstract
Objective: To investigate the role of adenosine diphosphate ribosylation factor 6 (Arf6) in the pathogenesis of endometriosis. Methods: Endometrial tissues were sampled from women who were hospitalized in the Affiliated Hospital of Medical School of Ningbo University and Ningbo Women and Children's Hospital from November 2020 to May 2021 with endometriosis (n=44, endometriosis group) and without endometriosis (n=17, control group). The expression of Arf6 protein in the endometrial tissues was detected by western blot. Endometrial epithelial cells from both groups were primary cultured and the distribution of intracellular mitochondria was detected by immunofluorescence. The expression of Arf6 protein was down-regulated by small interference RNA (siRNA), the distribution of mitochondria in cells with decreased Arf6 protein expression was observed, and the expression of mitochondria-related proteins development and differentiation enhancing factor 1 (DDEF1, also called AMAP1), reactive oxygen species 1 (ROS1) and epithelial-mesenchymal transition (EMT)-related proteins E-cadherin, vimentin were detected. Transwell assay was used to detect the changes in the migration ability of the cells. Results: Compared with the control group, ectopic endometrial tissue of endometriosis group showed high expression of Arf6 protein (0.174±0.019 vs 0.423±0.033; t=29.630, P<0.01); and in ectopic endometrial epithelial cells, mitochondria were distributed near the edge of the cell membrane. While Arf6 expression was down-regulated by siRNA, the distribution of mitochondria in ectopic cells returned to natural, close to the control level. In addition, the expression levels of AMAP1 and ROS1 in ectopic cells after Arf6 protein knockdown were significantly decreased. Transwell assay results indicated that knockdown of Arf6 could reduce the migration ability of ectopic epithelial cells [migration cell count: (34.3±7.5) cells]; and immunofluorescence verified low expression of E-cadherin but high expression of vimentin in ectopic epithelial cells, whereas knockdown of Arf6 protein E-cadherin expression increased but vimentin expression decreased. Conclusions: High expression of Arf6 protein in ectopic endometrial epithelial cells leads to the distribution of mitochondria tending to membrane marginalization, while inducing EMT, which are involved in the mechanism of endoheterosis pathogenesis.

Abstract
Objective: To investigate the prenatal diagnosis and prognostic factors of fetal sacrococcygeal teratoma (SCT). Methods: A retrospective analysis was performed on 41 pregnant women who were diagnosed with fetal SCT by prenatal ultrasound at the Women's Hospital, Zhejiang University School of Medicine from January 2014 to September 2021. The prenatal imaging features and pregnancy outcomes, including tumor volume to fetal weight ratio (TFR), proportion of solid tumor, tumor growth rate (TGR), fetal hydrops, placentomegaly and polyhydramnios were analyzed. Receiver operating characteristic (ROC) curve was used to determine the critical values of TFR and TGR for predicting adverse fetal outcomes. Results: (1) Among the 41 pregnant women with fetal SCT, the diagnostic gestational week of ultrasound was (24.2±2.9) weeks (range: 18-28 weeks). Among them, 1 case progressed to fetal hydrops and induced labor at 22 weeks of gestation, 1 case developed intrauterine death and induced labor at 29 weeks of gestation, and 39 pregnancies continued until delivery. Among the 39 cases of continued pregnancy, 1 case underwent cesarean section at 31 weeks of gestation due to malignant polyhydramnios and increased fetal cardiothoracic ratio in the third trimester, 1 case underwent cesarean section at 32 weeks of gestation due to fetal heart failure, and 1 case underwent cesarean section at 32 weeks of gestation due to fetal heart failure and hydrops. The other 36 cases underwent surgical resection of tumor within 3 weeks after birth with good prognosis. (2) TFR>0.12 before 28 weeks of gestation could predict poor fetal prognosis, with a sensitivity of 100.0%, a specificity of 86.1% and an area under curve (AUC) of 0.922 (P<0.01). Among the fetuses with TFR>0.12, 5/10 had poor prognosis, while the fetuses with TFR≤0.12 all had good prognosis (100%,31/31), and the difference between the two groups was statistically significant (P<0.001). (3) TGR>48 cm3/week could predict poor fetal prognosis with a sensitivity of 100.0%, a specificity of 78.3% and an AUC of 0.880 (P<0.05). (4) Among the 28 SCT fetuses delivered in our hospital, the incidence rate of poor fetal prognosis was 0 (0/20) in those with solid tumor component<50%, and 5/8 in those with solid tumor component ≥50%, and the difference between the two groups was statistically significant (P<0.01). The incidence rate of poor fetal prognosis was 2/2 in those with placentomegaly (all with fetal hydrops), and 12% (3/26) in those without placentomegaly. The risk of poor fetal prognosis was 8.67 times higher in those with placentomegaly than those without placentomegaly, and the difference between the two groups was statistically significant (P<0.05). The incidence rate of poor fetal prognosis in those with polyhydramnios was 3/7, and 10% (2/21) in those without polyhydramnios, but there was no statistically significant difference between the two groups (P>0.05). Conclusion: TFR combined with solid tumor morphology, TGR, and presence of placentomegaly could predict the adverse pregnancy outcomes of fetal SCT.

Abstract
Studies have shown that autoimmune disease (AID)-related ulcers are disease complications that lead to serious poor prognosis such as infection and disability. It is difficult to make a clear diagnosis and there are contradictions between the applications of immunosuppressive therapy and anti-infectious therapy. Improper diagnosis and immunosuppressive therapy can easily delay the timing of anti-infectious therapy and surgery for patients, which bring adverse effects on the prognosis of patients. This paper reviews the concept, clinical characteristics and treatment suggestions of each subtype of AID-related ulcers, in order to provide more ideas for AID-related ulcers' clinical diagnosis and treatment.

Abstract
Objective: To summarize the clinical phenotype of patients with developmental and epileptic encephalopathy 85 caused by SMC1A gene truncating variation. Methods: The clinical data of 4 patients with epileptic encephalopathy caused by SMC1A gene truncating variation from August 2016 to June 2020 were analyzed retrospectively. Related literatures up to October 2021 with the key words "SMC1A" "Developmental and epileptic encephalopathy 85" "SMC1A, epilepsy" and "SMC1A, truncating" in PubMed, CNKI, and Wanfang databases were searched. Relevant literature was summarized and reviewed. Results: These 4 patients were all female. The onset age of seizure were all in the infantile period. They were admitted to the hospital at 3, 2, 11 and 18 months respectively. Focal seizures occurred in all 4 patients, while 1 of them experienced infantile spasm. The characteristic of cluster was observed in all of them with an interval of 14 days to 5.0 months. The seizures were all refractory to different kinds of anti-seizure medications. All 4 patients had severe developmental retardation with microcephaly (head circumference<-2 s). The interictal electroencephalogram (EEG) was characterized by diffuse slow wave. The 4 SMC1A gene variants were p.Gly655fs, p.Glu811fs, p.Arg412fs and p.Ile143fs, all of which were de novo frameshift variation after parental validation. There were another 17 cases with SMC1A gene truncating variation reported in 6 English articles and 1 Chinese article. Among these 21 patients, who were all female, the onset of seizures occurred between 0.5 and 18.0 months of age. Seventeen cases (81%) had the characteristics of cluster attacks, and the intervals of attack cycles were different. Seizure types included generalized tonic-clonic seizure (12 cases (57%)), focal seizure (11 cases(52%)), myoclonic(4 cases(19%)), spasm (4 cases(19%)), atypical absence (3 cases(14%)), tonic seizure (2 cases (10%)), and atonia (1 case(5%)). In addition, 4 cases (19%) had status epilepsy. All patients had moderate to severe mental retardation. Microcephaly was found in all patients. Among 18 cases,EEG in 8 cases had diffuse slow wave background. Brain magnetic resonance imaging (MRI) was normal in 13 cases (62%). Other MRI changes included cerebellar atrophy (3 cases), thin corpus callosum (3 cases), and lateral ventricular enlargement (2 cases). Twenty patients did not respond well to antiepileptic drugs. Conclusions: The clinical phenotypes of patients with epilepsy encephalopathy 85 caused by SMC1A gene truncating variation are characterized by female, early-onset, clustering of seizures, development delay and microcephaly. Diffuse slow waves are shown in interictal EEG in partial. Response to treatment and prognosis are poor.

Abstract
Objective: To analyze the difference between Z score and previous criteria in the diagnosis characteristics of coronary artery aneurysm (CAA) in Kawasaki disease, and to investigate the clinical distribution of Kawasaki disease CAA in the Z score group. Methods: This study retrospectively analyzed the clinical and echocardiographic data of 2 419 children with Kawasaki disease in Shenzhen Children's Hospital from January 2009 to December 2019. The traditional criteria and Z score criteria were used to diagnose CAA, and the differences of diagnostic efficiency between the 2 diagnostic methods were analyzed. The clinical distribution characteristics of CAA in children with Kawasaki disease were analyzed by grouping their sex, clinical classification (complete Kawasaki disease, incomplete Kawasaki disease) the sensitivity to intravenous immunoglobulin (IVIG) (IVIG-sensitive Kawasaki disease,IVIG-unresponsive Kawasaki disease). And the course of the disease (≤6 weeks, >6-8 weeks, >8 weeks to 6 months) etc. The χ² test or Kruskal-Wallis test was used for comparison between the groups, and the Kappa test was used for consistency evaluation. Results: Among the 2 419 children with Kawasaki disease, 1 558 were males and 861 were females. The age of onset was 1.8 (1.0, 3.2) years. The rate of CAA by Z score criteria was higher than that by traditional method (21.9% (529/2 419) vs. 13.9% (336/2 419), χ2=1 074.94, P<0.001). Compared to the traditional method, the Z score criteria found higher rate of CAA in male patients, patients with incomplete Kawasaki disease, and IVIG-unresponsive patients (25.2% (392/1 558) vs. 16.0% (249/1 558), (32.7% (166/507) vs. 19.5% (99/507), 30.5% (95/312) vs. 24.0% (75/312), χ2=694.05, 216.19, 184.37, all P<0.001). The Z score criteria was consistent with the traditional method in diagnosing CAA (κ=0.642,P<0.001). Moreover, in the Z score criteria, the rate of CAA in males (25.2%, 392/1 558) was higher than that in females (15.9%, 137/861), higher in incomplete Kawasaki cases (32.7%, 166/507) than that in complete Kawasaki case (19.0%, 363/1 912), and higher in IVIG-unresponsive cases (30.4%, 95/312) than that in IVIG-sensitive cases (20.6%, 434/2 107), with statistically significant differences (χ2=27.76, 44.38, 15.43, all P<0.001). Coronary Z score of course ≤ 6 weeks was greater than that of course between>6-8 weeks and >8 weeks to 6 months (1.3 (0.7, 2.3) vs. 0.7 (0.3, 1.4), 0.7 (0.3, 1.3), Z=20.65, 13.70, both P<0.001). Conclusions: The rate of CAA in Kawasaki disease by Z score criteria is higher than that by traditional method. In the Z score group, most CAA occur within 6 weeks of the course of the disease, and the rate of CAA in male, incomplete Kawasaki disease, and IVIG-unresponsive is higher.

Abstract
Most effector T cells will undergo programmed apoptosis after an immune response and some of them may become memory T cells. According to the distribution and functional status, the memory T cells can be divided into effector central memory T cells (TCM), effector memory T cells (TEM) and tissue-resident memory T cells (TRM) cells. TRM cells, including CD4+ TRM and CD8+ TRM cells, colonize various barrier surfaces and are no longer involved in lymphocyte recycling, closely monitored for local perturbations in homeostasis throughout the body as a critical component of the first defense line. When pathogenic microorganisms invade the body, TRM cells can quickly produce a defense response to initiate innate immunity and adaptive immunity by producing cytokines or killer molecules to resist viral and bacterial infections. In addition, TRM cells are also involved in cancer surveillance and play an essential role in maintaining cancer-immune equilibrium. The high frequency of TRM cells in tumor tissues often means favorable survival for patients. The latest research proves that TRM cells also play an important role in vaccine development and pathological features of COVID-19. This article will summarize the biological functions of TRM cells and aims at providing references for further research on their mechanism and for targeting the best treatment of clinical disease.

Abstract
BackgroundThe Centers for Disease Control and Prevention recommends an additional dose (AddDose) of COVID-19 vaccine for moderately/severely immunosuppressed individuals following an initial vaccine series. The American College of Rheumatology suggests that patients interrupt use (hold) certain DMARDs around the time of COVID-19 vaccination to improve immunogenicity. Whether holding DMARDs around an AddDose of COVID-19 vaccine affects RA disease activity or affects frequencies of lymphocyte populations that may be associated with RA disease activity remains unknown.ObjectivesTo test whether RA disease activity and frequencies of lymphocyte populations change pre- vs. post-AddDose of COVID-19 vaccine, overall and stratified by holding vs. continuation of DMARDs around the AddDose.MethodsProspective observational cohort study of patients with RA who had completed an initial COVID-19 vaccine series (2 doses of mRNA vaccine or 1 dose of adenovirus vector vaccine). Subjects enrolled July-November 2021, prior to receiving an AddDose. Subjects held or continued DMARDs around the AddDose based on discussion with their rheumatologist and/or personal decision-making. RA disease activity was assessed weekly using the validated patient-reported RA Disease Activity Index-5 (RADAI-5) from enrollment through 4 weeks post-AddDose. We compared mean RADAI-5 pre- vs. post-AddDose using generalized estimating equations to account for correlated data among individual subjects. We aimed to enroll 60 subjects to achieve 91% power to detect a 15% non-inferiority margin in mean RADAI-5 post- vs. pre-AddDose. A subset of subjects with seropositive RA provided blood for flow cytometry at enrollment and week 4 post-AddDose. Frequencies of lymphocyte populations (T peripheral helper [Tph] cells, T follicular helper [Tfh] cells, age-associated B cells [ABC], and plasmablasts) were compared pre- vs. post-AddDose using Wilcoxon paired tests with Bonferroni correction.ResultsAmong 71 subjects, mean age was 62 (SD 12) years, 85% were female, and 87% had seropositive RA. Methotrexate (42%) and TNF inhibitors (38%) were the most common DMARDs; 21% were taking prednisone. One subject reported COVID-19 infection prior to the AddDose. The mean RADAI-5 was 3.20 (SD 0.23) pre-AddDose compared to 3.25 (SD 0.23) after (difference of 1.6%, p=0.51). Figure 1 displays mean RADAI-5 in 35 (49%) subjects that held at least 1 DMARD and 36 (51%) subjects that continued all DMARDs around the AddDose. Mean change in RADAI-5 between pre- vs. post-AddDose did not significantly differ based on whether subjects held vs. continued DMARDs (p for interaction = 0.16). Frequencies of Tph, Tfh, ABC, and plasmablast populations did not significantly differ between the pre- and post-AddDose timepoints in subjects that held at least 1 DMARD (n=16) or subjects that continued all DMARD (n=11) (Figure 1).ConclusionRA disease activity, measured weekly with a validated patient-reported outcome, is stable around the time of an AddDose of COVID-19 vaccine. Lymphocyte subsets of interest in RA were also similar before and after the AddDose, supporting the observation of stable patient-reported RA disease activity. Holding DMARDs was not associated with greater RA disease activity following the AddDose.Disclosure of InterestsSara Tedeschi Consultant of: NGM Biopharmaceuticals: payment to Dr. Tedeschi, Grant/research support from: Moderna: research support to institution, Jacklyn Stratton: None declared, Jack Ellrodt: None declared, Mary Grace Whelan: None declared, Keigo Hayashi: None declared, Kazuki Yoshida Consultant of: OM1, Inc: consulting fees paid to Dr. Yoshida, Lin Chen: None declared, Ifeoluwakiisi Adejoorin: None declared, Kathryne E.

Abstract
PURPOSE A significant barrier to adoption of de-escalated treatment protocols for human papillomavirus-driven oropharyngeal cancer (HPV-OPC) is that few predictors of poor prognosis exist. We conducted the first large whole-genome sequencing (WGS) study to characterize the genetic variation of the HPV type 16 (HPV16) genome and to evaluate its association with HPV-OPC patient survival. PATIENTS AND METHODS A total of 460 OPC tumor specimens from two large United States medical centers (1980-2017) underwent HPV16 whole-genome sequencing. Site-specific variable positions [single nucleotide polymorphisms (SNPs)] across the HPV16 genome were identified. Cox proportional hazards model estimated hazard ratios (HRs) and 95% confidence intervals (CIs) for overall survival by HPV16 SNPs. Harrell C-index and time-dependent positive predictive value (PPV) curves and areas under the PPV curves were used to evaluate the predictive accuracy of HPV16 SNPs for overall survival. RESULTS A total of 384 OPC tumor specimens (83.48%) passed quality control filters with sufficient depth and coverage of HPV16 genome sequencing to be analyzed. Some 284 HPV16 SNPs with a minor allele frequency ≥1% were identified. Eight HPV16 SNPs were significantly associated with worse survival after false discovery rate correction (individual prevalence: 1.0%-5.5%; combined prevalence: 15.10%); E1 gene position 1053 [HR for overall survival (HRos): 3.75, 95% CI 1.77-7.95; Pfdr = 0.0099]; L2 gene positions 4410 (HRos: 5.32, 95% CI 1.91-14.81; Pfdr = 0.0120), 4539 (HRos: 6.54, 95% CI 2.03-21.08; Pfdr = 0.0117); 5050 (HRos: 6.53, 95% CI 2.34-18.24; Pfdr = 0.0030), and 5254 (HRos: 7.76, 95% CI 2.41-24.98; Pfdr = 0.0030); and L1 gene positions 5962 (HRos: 4.40, 95% CI 1.88-10.31; Pfdr = 0.0110) and 6025 (HRos: 5.71, 95% CI 2.43-13.41; Pfdr = 0.0008) and position 7173 within the upstream regulatory region (HRos: 9.90, 95% CI 3.05-32.12; Pfdr = 0.0007). Median survival time for patients with ≥1 high-risk HPV16 SNPs was 3.96 years compared with 18.67 years for patients without a high-risk SNP; log-rank test P < 0.001. HPV16 SNPs significantly improved the predictive accuracy for overall survival above traditional factors (age, smoking, stage, treatment); increase in C-index was 0.069 (95% CI 0.019-0.119, P < 0.001); increase in area under the PPV curve for predicting 5-year survival was 0.068 (95% CI 0.015-0.111, P = 0.008). CONCLUSIONS HPV16 genetic variation is associated with HPV-OPC prognosis and can improve prognostic accuracy.

Abstract
General muscle health declines with age, and in particular, sarcopenia-defined as progressive loss of muscle mass and strength/physical performance-is a growing issue in Asia with a rising population of community-dwelling older adults. Several guidelines have addressed early identification of sarcopenia and management, and although nutrition is central to treatment of sarcopenia, there are currently few guidelines that have examined this specifically in the Asian population. Therefore, the Asian Working Group for Sarcopenia established a special interest group (SIG) comprising seven experts across Asia and one from Australia, to develop an evidence-based expert consensus. A systematic literature search was conducted using MEDLINE on the topic of muscle health, from 2016 (inclusive) to July 2021, in Asia or with relevance to healthy, Asian community-dwelling older adults (≥60 years old). Several key topics were identified: (1) nutritional status: malnutrition and screening; (2) diet and dietary factors; (3) nutritional supplementation; (4) lifestyle interventions plus nutrition; and (5) outcomes and assessment. Clinical questions were developed around these topics, leading to 14 consensus statements. Consensus was achieved using the modified Delphi method with two rounds of voting. Moreover, the consensus addressed the impacts of COVID-19 on nutrition, muscle health, and sarcopenia in Asia. These statements encompass clinical expertise and knowledge across Asia and are aligned with findings in the current literature, to provide a practical framework for addressing muscle health in the community, with the overall aim to encourage and facilitate broader access to equitable care for this target population.

Abstract
BackgroundCT-P13 is an approved biosimilar to EU-approved and US-licensed Infliximab (INX) for the indications of rheumatoid arthritis (RA), adult and paediatric Crohn’s disease, adult and paediatric ulcerative colitis, ankylosing spondylitis, psoriatic arthritis and psoriasis.ObjectivesThe purpose of this study was to demonstrate equivalence of efficacy and compare PK and safety profiles of CT-P13 and China-approved INX.MethodsIn this randomized, double blinded, multicenter, parallel-group, phase III study, patients with active RA who had been responding inadequately to methotrexate for at least 3 months, were randomized to receive either CT-P13 or China-approved INX. Patients were treated with doses of 3 mg/kg at Weeks 0, 2, 6, then every 8 weeks up to Week 54. Prior to dosing at Week 30, patients randomized to China-approved INX underwent a second randomization either to continue China-approved INX or to switch to CT-P13 at Week 30. Results of patients who underwent transition to CT-P13 were included in the China-approved INX group. The primary efficacy endpoint was change in DAS28 (CRP) from baseline to Week 14, which was analyzed using an analysis of covariance. Equivalence was determined if the 90% CI for the estimate of treatment difference was entirely contained within the predefined equivalence margin of -0.6 to 0.6.Results270 patients were randomly assigned to 2 treatment groups in a 1:1 ratio (136 and 134 patients in the CT-P13 and China-approved INX groups, respectively) and 184 patients completed the study. The least square mean change (standard error) of DAS28 (CRP) from baseline to Week 14, -1.566 [0.1419] and -1.547 [0.1491], was similar between the CT-P13 and China-approved INX groups, respectively. The 90% CI for the estimate of treatment difference (-0.29, 0.25) was contained within the predefined equivalence margin, which demonstrated therapeutic equivalence between the groups. The mean actual values for DAS28 (CRP) decreased from baseline to Week 54 and were similar between the groups (Figure 1). Additional efficacy endpoints, including ACR responses (ACR20 at Week 14; 60.6%, 54.8% and at Week 54; 65.1%, 60.6% in the CT-P13 and China-approved INX groups, respectively), EULAR responses, CDAI, and SDAI, were similar between the groups, even after switching at Week 30. During the study, mean serum INX concentrations were similar between the groups. Between Weeks 14 and 22, mean (percent coefficient of variation) AUCτ were 11156333.615 (44.796) ng·h/mL and 11462884.280 (51.057) ng·h/mL, and Cmax,ss were 66577.2 (31.4) ng/mL and 66356.1 (21.0) ng/mL in the CT-P13 and China-approved INX groups, respectively, which were similar between the groups. Most treatment-emergent AEs were grade 1 or 2 in intensity. One malignancy was reported in the CT-P13 group and no deaths were reported. The proportions of patients with anti-drug antibodies were similar between the groups, even after switching at Week 30. The overall safety profile of CT-P13 was comparable to that of China-approved INX and no new safety issues were observed (Table 1).Table 1.Summary of Safety ResultsNumber of patients (%)CT-P13 (N=136)China-approved Infliximab (N=133)Treatment-emergent AEsTotal115 (84.6%)107 (80.5%)Related97 (71.3%)86 (64.7%)Treatment-emergent serious AEsTotal17 (12.5%)12 (9.0%)Related10 (7.4%)6 (4.5%)Infusion related reaction/ hypersensitivity/anaphylactic reactionsTotal(=Related)20 (14.7%)19 (14.3%)InfectionsTotal45 (33.1%)43 (32.3%)Related36 (26.5%)40 (30.1%)Note: Summary is presented for the safety population who received at least 1 dose (full or partial) of study drug.ConclusionThe study demonstrated that efficacy of CT-P13 is equivalent to that of China-approved INX. Also, the PK and safety profiles of CT-P13 were comparable to those of China-approved INX. No loss of efficacy or difference in safety or immunogenicity was observed after switching from China-approved INX to CT-P13 at Week 30.Disclosure of InterestsJonathan Kay Consultant of: Boehringer Ingelheim GmbH; Pfizer Inc.; Samsung Bioepis; Sandoz Inc., Grant/research support from: Pfizer Inc.

Abstract
BackgroundIn SELECT-PsA 1, patients (pts) with psoriatic arthritis (PsA) and an inadequate response or intolerance to ≥1 non-biologic disease-modifying antirheumatic drug showed improvement in the signs and symptoms of PsA with upadacitinib 15 mg (UPA15) or 30 mg (UPA30), an oral Janus kinase (JAK) inhibitor, through week (wk) 56.1ObjectivesTo evaluate the efficacy and safety of UPA and UPA vs adalimumab (ADA) at wk 104 from the ongoing long-term extension of SELECT-PsA 1.MethodsPts received UPA15, UPA30, ADA 40 mg, or placebo (PBO) for 24 wks, at which point, PBO pts switched to UPA15 or UPA30. Efficacy endpoints were analyzed using non-responder imputation (NRI) and as observed (AO) (binary endpoints) or mixed-effect model repeated measures and AO (continuous endpoints), with nominal P-values shown, for continuous UPA and ADA treatment groups. Treatment-emergent adverse events were summarized for pts who received ≥1 dose of study drug using a visit-based cut-off at wk 104.Results1704 pts received ≥1 dose of study drug. At wk 104, 25.4% of patients had discontinued study drug. The proportions of pts who achieved ACR20/50/70, MDA, PASI75/90/100, and resolution of enthesitis or dactylitis showed consistent responses, or further improvements, from wk 561 to wk 104 (Table 1). ACR20/50/70 and MDA responses, as well as mean change from baseline (BL) in HAQ-DI, patient’s assessment of pain, BASDAI, and ASDAS, were greater with UPA vs ADA. Mean change from BL in modified total Sharp/van der Heijde Score (mTSS) was generally similar across groups and comparable to wk 56.1 The safety profile of UPA was generally comparable to ADA (Figure 1) and consistent with wk 561 data. Rates of serious infection, herpes zoster, lymphopenia, and elevated CPK remained numerically higher with UPA30 vs UPA15; rates in both UPA groups were higher vs ADA. Rates of malignancies, MACE, or VTE were similar across groups, and consistent with wk 561 data. Two deaths were reported with UPA15, 1 with UPA30, and 1 with ADA.Table 1.Efficacy Endpoints at Week 104EndpointUPA15(n=429)UPA30(n=423)ADA(n=429)Proportion of Pts (%)aNRIAONRIAONRIAOACR2069.087.969.587.963.485.1ACR5053.667.459.3*74.147.162.3ACR7038.0*47.443.5*54.429.439.1Minimal Disease Activity (MDA)42.054.845.9*56.837.850.3PASI75b57.973.462.478.658.876.5PASI90b46.759.053.366.548.863.3PASI100b34.143.442.451.434.144.0Resolution of enthesitis by LEIc53.375.552.272.049.173.9Resolution of dactylitis by LDId69.994.571.796.272.495.2Change from BLeMMRMAOMMRMAOMMRMAOHealth Assessment Questionnaire - Disability Index (HAQ-DI)-0.55*-0.57-0.55*-0.59-0.45-0.47Patient’s assessment of pain (numeric rating scale)-3.3-3.5-3.4*-3.6-3.0-3.2Bath Ankylosing Spondylitis Disease Activity Index (BASDAI)f-3.0-3.2-3.3-3.6-2.7-2.6Ankylosing Spondylitis Disease Activity Score (ASDAS)f-1.6-1.8-1.9*-2.1-1.5-1.6Modified total Sharp/van der Heijde Score (mTSS)0.030.010.010.000.110.11ACR20/50/70, ≥20%/50%/70% improvement in American College of Rheumatology criteria; ADA, adalimumab; AO, as observed; BL, baseline; LDI, Leeds Dactylitis Index; LEI, Leeds Enthesitis Index; MMRM, mixed effect model repeated measurement; NRI, non-responder imputation; PASI75/90/100, ≥75%/90%/100% improvement in Psoriasis Area and Severity Index; pts, patients; UPA, upadacitinib.aData shown as NRI and AO for binary endpoints.bFor pts with psoriasis affecting ≥3% of body surface area at BL.cFor pts with LEI >0 at BL; resolution LEI=0.dFor pts with LDI >0 at BL; resolution LDI=0.eData shown as MMRM (LS mean) and AO (mean) for continuous endpoints.fFor pts with psoriatic spondylitis at BL.Nominal *P<0.05, UPA15 or UPA30 vs ADA for NRI and MMRM; AO descriptive only.ConclusionIn PsA pts, efficacy responses were similar or greater with UPA15 or UPA30 vs ADA at wk 104, and inhibition of radiographic progression was maintained.

Abstract
BackgroundUpadacitinib (UPA), an oral Janus kinase (JAK) inhibitor, demonstrated efficacy and safety in patients (pts) with psoriatic arthritis (PsA) and prior inadequate response or intolerance to ≥1 biologic disease-modifying antirheumatic drug (bDMARD) at week (wk) 56 in the phase 3 SELECT-PsA 2 study.1ObjectivesTo evaluate the efficacy and safety of UPA at wk 104 from the ongoing long-term extension of SELECT-PsA 2.MethodsPts were randomized to UPA 15 mg (UPA15), UPA 30 mg (UPA30), or placebo (PBO) for 24 wks; PBO pts were then switched to UPA15 or UPA30. For continuous UPA treatment groups, efficacy endpoints at wk 104 were analyzed using non-responder imputation (NRI) and as observed (AO) (binary endpoints) or mixed-effect model repeated measures (MMRM) and AO (continuous endpoints). Treatment-emergent adverse events (TEAEs) were summarized for pts who received ≥1 dose of study drug using visit-based cut-off at wk 104.ResultsA total of 641 pts received ≥1 dose of study drug. At wk 104, 38.4% of all patients had discontinued study drug, with the highest discontinuation observed in patients randomized to PBO at baseline (all PBO: 46.7%). The most common reasons for discontinuation were lack of efficacy (UPA15: 12.3%, UPA30: 8.7%, all PBO: 21.7%) and adverse event (UPA15: 10.9%, UPA30: 13.3%, all PBO: 12.7%). The proportion of UPA pts that achieved ACR20/50/70, MDA, PASI75/90/100, and resolution of dactylitis and enthesitis were generally similar, or further improved, with 104 wks of treatment vs 56 wks1 (Table 1). Similarly, mean change from baseline in HAQ-DI, patient’s assessment of pain, BASDAI, and ASDAS was improved with UPA treatment. At 104 wks of therapy, clinical responses were largely similar with UPA15 and UPA30. Generally, safety data at wk 104 (Figure 1) were consistent with that reported at wk 56.1 Rates of serious infection, herpes zoster, hepatic disorder, anemia, neutropenia, lymphopenia, and CPK elevation remained numerically higher with UPA30 vs UPA15, while rates of malignancies, MACE, and VTE were similar for both UPA groups. One death was reported with UPA15 (unexplained due to lack of information; however, the patient had recently been diagnosed with ovarian cancer) and 2 with UPA30 (pancytopenia and COVID-19 pneumonia).Table 1.Efficacy Endpoints at Week 104EndpointUPA15 (n=211)UPA30 (n=218)Proportion of Pts (%)aNRIAONRIAOACR2055.580.354.681.8ACR5044.562.939.959.4ACR7023.232.221.631.5Minimal Disease Activity (MDA)29.441.333.949.3PASI75b47.769.852.781.1PASI90b37.755.244.367.8PASI100b23.135.435.955.6Resolution of enthesitis by LEIc39.867.837.568.4Resolution of dactylitis by LDId54.597.452.096.9Change from BLeMMRMAOMMRMAOHealth Assessment Questionnaire - Disability Index (HAQ-DI)-0.36-0.39-0.50-0.53Patient’s assessment of pain (numeric rating scale)-2.7-3.0-2.9-3.1Bath Ankylosing Spondylitis Disease Activity Index (BASDAI)f-2.6-3.0-2.6-2.9Ankylosing Spondylitis Disease Activity Score (ASDAS)f-1.4-1.7-1.3-1.5ACR20/50/70, ≥20%/50%/70% improvement in American College of Rheumatology criteria; AO, as observed; BL, baseline; LDI, Leeds Dactylitis Index; LEI, Leeds Enthesitis Index; MMRM, mixed effect model repeated measurement; NRI, non-responder imputation; PASI75/90/100, ≥75%/90%/100% improvement in Psoriasis Area and Severity Index; pts, patients; UPA, upadacitinib.aData shown as NRI and AO for binary endpoints.bFor pts with psoriasis affecting ≥3% of body surface area at BL.cFor pts with LEI >0 at BL; resolution LEI=0.dFor pts with LDI >0 at BL; resolution LDI=0.eData shown as MMRM (LS mean) and AO (mean) for continuous endpoints.fFor pts with psoriatic spondylitis at BL.ConclusionIn PsA pts with prior inadequate response or intolerance to ≥1 bDMARD, clinical responses were maintained with UPA15 and UPA30 up to 2 years of treatment.

Abstract
BackgroundImmune checkpoint inhibitor (ICI) therapies that promote T cell activation have improved outcomes for advanced malignancies yet can also elicit harmful autoimmune reactions. The T cell mechanisms mediating these iatrogenic autoimmune events remain unclear.ObjectivesTo investigate the immunophenotype, transcriptomic feature and clonotypes of T cells from joints of patients affected by ICI-induced inflammatory arthritis (ICI-arthritis).MethodsDetailed immunophenotyping was performed on mononuclear cells from synovial fluid (SF) using mass cytometry and flow cytometry to identify significantly altered populations in ICI-A compared to seropositive rhrumatoid arthritis (RA) and psoriatic arthritis (PsA) (p<0.05). Bulk RNA-seq was performed on altered SF CD8 T cell subsets from ICI-A, RA and PsA to investigate their transcriptomic features. Cytokine profile and pathways enriched in ICI-A CD8 T cells were examined using differentially expressed genes, intracellular staining, and in vitro culture. TCR clonotypes were examined using single cell RNA-seq of T cells from synovial fluid, tissue and blood of ICI-A.ResultsCompared to the autoimmune arthritides RA and PsA, ICI-arthritis joints contained an expanded CD38hi CD127- CD8+ T cell subset that displays cytotoxic, effector, and interferon (IFN) response signatures. Exposure of synovial T cells to Type I IFN, more so than IFN-γ, induced the CD38hi cytotoxic phenotype. Single cell transcriptomic and T cell repertoire (TCR) analyses indicated that the abundance of CD38hi CD8 T cells in ICI-arthritis resulted from proliferation of a limited number of clones. The CD38hi population appeared distinct from dysfunctional T cells and clonally most related to TCF7+ memory populations. Comparison of synovial tissue from bilateral knees of the same patient demonstrated considerable sharing of TCR clonotypes among CD38hi CD8 T cells between the two joints. Further, TCR clonotypes expanded in synovial fluid of ICI-arthritis patients were detected in circulating T cells, and circulating CD38hi CD8 T cells are also expanded in ICI-arthritis patients.ConclusionThese results define a distinct CD8 T cell subset in the synovial fluid and in the circulation of patients with ICI-A that may be directly activated by ICI therapy to mediate a tissue-specific autoimmune response.Disclosure of InterestsNone declared.

Abstract
Objective: To explore the role and specific mechanism of glucocorticoids in preventing stenosis after esophageal endoscopic submucosal dissection (ESD). Methods: Data of 81 patients [51 cases were male and 30 cases were female, aged (62.09±7.95) years] undergoing early esophageal cancer or precancerous lesions with a stripping range ≥3/4 circle hospitalized from January 2019 to February 2021 in Department of Gastroenterology, Zhongda Hospital, Southeast University. They were randomly divided into the control group (n=23), oral prednisone acetate group (n=28) and/or combined with local injection Triamcinolone acetonide group (n=30). Analysis the stenosis rates, endoscopic stent dilatation times, the scores of the Atkinson classification and QLQ-OES18 after 12 weeks. Also the expression of carbohydrate sulfotransferase15 (CHST15) mRNA, TGF-β1 and Collagen-Ⅰ protein were compared by real-time PCR or immunohistochemistry. Results: The stenosis rates of the control group, oral prednisone acetate group and/or combined with local injection Triamcinolone acetonide group were 82.6% (19/23), 46.4% (13/28) and 20.0% (6/30) (P<0.001); endoscopic stent dilatation times [M (Q1,Q3)] in these three groups were 2 (1, 3), 0 (0, 0) and 0 (0, 0) (P<0.001). After ESD, the scores of the Atkinson classification and QLQ-OES18 in the three groups were lower than before (P<0.001); and the expression of CHST15 mRNA in the three groups were 4.31±0.13, 3.44±0.07 and 2.84±0.21 respectively (P<0.001). Compared with the control group, the expression of CHST15 mRNA in oral prednisone acetate group was down-regulated (P<0.001), and was the lowest in oral prednisone acetate combined with local injection Triamcinolone acetonide group (P<0.001). As CHST15 mRNA was down-regulated, the expression of TGF-β1 and Collagen-I protein was also down-regulated (P<0.05). Conclusions: Oral prednisone alone or combined with local injection of triamcinolone acetonide both can prevent esophageal stenosis effectively. Oral combined with local injection of glucocorticoid is particularly more effective. Glucocorticoid can reduce the expression of CHST15 mRNA, thereby inhibiting the expression of TGF-β1 and Collagen-I protein.

Abstract
UNLABELLED Objective: To explore the feasibility and preliminary technical experience of the double-tract reconstruction combined with π-shaped esophagojejunal anastomosis after total laparoscopic proximal gastrectomy (TLPG) in the treatment of adenocarcinoma of esophagogastric junction (AEG). Methods: A descriptive case series study method was used. Clinical data of 12 AEG patients who underwent the double-tract reconstruction combined with π-shaped esophagojejunal anastomosis after TLPG from January 2021 to June 2021 at the Department of General Surgery, First Medical Center, PLA General Hospital were retrospectively analyzed. Among the 12 patients, the median tumor diameter was 2.0 (1.5-2.9) cm, and the pathological stage was T1-3N0-3aM0. All the patients routinely underwent TLPG and D2 lymph node dissection with double-tract reconstruction combined with π-shaped esophagojejunal anastomosis: (1) Double-tract reconstruction combined with π-shaped esophagojejunal anastomosis: mesentery 25 cm away from the Trevor ligament was treated, and an incision of about 1 cm was made on the mesenteric border of the intestinal wall and the right wall of the esophagus, two arms of the linear cutting closure were inserted, and esophagojejunal side-to-side anastomosis was performed. A linear stapler was used to cut off the lower edge of the anastomosis and close the common opening to complete the esophagojejunal π-shaped anastomosis. (2) Side-to-side gastrojejunostomy anastomosis: an incision of about 1 cm was made at the jejunum to mesenteric border and at the greater curvature of the remnant stomach 15 cm from the esophagojejunostomy, and a linear stapler was inserted to complete the gastrojejunostomy side-to-side anastomosis. (3) Side-to-side jejunojejunal anastomosis: an incision of about 1 cm was made at the proximal and distal jejunum to the mesangial border 40 cm from the esophagojejunostomy, and two arms of the linear stapler were inserted respectively to complete the side-to-side jejunojejunal anastomosis. A midline incision about 4-6 cm in the upper abdomen was conducted to take out the specimen, and an abdominal drainage tube was placed, then layer-by-layer abdominal closure was performed. INDICATIONS (1) adenocarcinoma of esophagogastric junction (Seiwert type II-III) was diagnosed by endoscopy and pathological examination; (2) ability to preserve at least 1/2 of the distal stomach after R0 resection of proximal stomach was evaluated preoperatively. CONTRAINDICATIONS (1) evaluation indicated distant metastasis of tumor or invasion of other organs; (2) short abdominal esophagus or existence of diaphragmatic hiatal hernia was assessed during the operation; (3) mesentery was too short or the tension was too high; (4) existence of severe comorbidities before surgery; (5) only palliative surgery was required in preoperative evaluation; (6) poor nutritional status. MAIN OUTCOME MEASURES operation time, intraoperative blood loss, postoperative complications, time to first flatus and time to start liquid diet, postoperative hospital stay, operation cost, etc. Continuous variables that conformed to normal distribution were presented as mean ± standard deviation, and those that did not conform to normal distribution were presented as median (Q1,Q3). Results: All the patients successfully completed TLPG with double-tract reconstruction combined with π-shaped esophagojejunal anastomosis, and postoperative pathology showed that no cancer cells were found on the upper incision margin. The operation time was (247.9±62.4) minutes, the median intraoperative blood loss was 100.0 (62.5, 100.0) ml, no intraoperative blood transfusion was required, the incision length was (4.9±1.0) cm, and the operation cost was (55.5±0.7) thousand yuan. The median time to start liquid diet was 1.0 (1.0, 2.0) days, and the mean time to flatus was (3.1±0.9) days. All the patients were discharged uneventfully. Only 1 patient developed postoperative paralytic ileus and infectious pneumonia with Clavien-Dindo classification of grade II. The patient recovered after conservative treatment. There was no surgery-related death. The postoperative hospital stay was (8.3±2.1) days. Conclusion: The double-tract reconstruction combined with π-shaped esophagojejunal anastomosis after TLPG is safe and feasible, which can minimize surgical trauma and accelerate postoperative recovery.

Abstract
Objective: To investigate the prevalence, awareness, treatment and control status of dyslipidemia among females aged ≥35 years old across China. Methods: Participants were selected by stratified multistage random sampling method in the "Twelfth Five-Year Plan" National Science and Technology Support Project "Survey on the Prevalence of Important Cardiovascular Diseases and Key Technology Research in China" project. This study is a retrospective, cross-sectional study. A total of 17 418 females aged 35 years and over were included in the current study. The basic information such as age, medical history and menopause was collected by questionnaire. The blood lipid parameters were derived from clinical laboratory examinations. The prevalence of dyslipidemia and the rate of awareness, treatment, and control of dyslipidemia were analyzed in females aged 35 years and over. Results: The age of participants was (56.2±13.0) years old, and the prevalence of dyslipidemia was 33.1% (5 765/17 418). The prevalence rates of high total cholesterol, hypertriglyceridemia, low HDL-C and high LDL-C were 9.7% (1 695/17 418), 11.1% (1 925/17 418), 10.9% (1 889/17 418) and 7.3% (1 262/17 418), respectively. The prevalence of dyslipidemia increased with age and the prevalence of dyslipidemia in women who were not married, Han, menarche age>16 years, obesity, central obesity, alcohol consumption, diabetes, hypertension and family history of cardiovascular disease were higher than those without such characteristics (P<0.05). There were 10 432 (59.9%) menopausal females in this cohort and prevalence of dyslipidemia of these participants was 38.8% (4 048/10 432), which was higher than that of non-postmenopausal females (24.6%, 1 717/6 986) (P<0.05). The awareness rates, treatment rates and control rates of dyslipidemia were 33.9% (1 953/5 765), 15.1% (870/5 765) and 2.5% (143/5 765) respectively among females aged 35 years and over in China. Conclusion: The prevalence of dyslipidemia in Chinese females aged 35 years and over is high, and its awareness, treatment, and control rates need to be optimized.

Abstract
Objective: To investigate the postoperative cardiopulmonary fitness of children with congenital heart diseases (CHD). Methods: This is a retrospective study. A total of 136 children after cardiac correction undergoing cardiopulmonary exercise test (CPET) in Shanghai Children's Medical Center from March 1 to June 30, 2021 were selected. According to the surgical procedure, the children were divided into two groups: the biventricular correction group (BV group) (n=75) and single ventricular correction group (SV group) (n=61). The BV group was divided into two subgroups: simple congenital heart disease (S-CHD) group (n=35) and complex congenital heart disease (C-CHD) group (n=40). CPET parameters, including VO2 max, VO2/kg max, VO2/kg@AT, O2/HR max, HRR, PetCO2 max, CI, HRR at 1 min, VE/VCO2 slope, OUES/kg and EOV, were analyzed. CPET parameters of patients underwent different procedure were compared. In the subgroup analysis, CPET parameters of patients in S-CHD group and C-CHD group were compared. The parameters of the BV group were compared with the normal value. Linear correlation analysis was used to identify the correlation between the CPET parameters. Results: A total of 136 children with CHD after surgery were enrolled. The age was (9.4±3.1) (ranged 6.2-16.0) years, and there was 84 (61.8%) male. All the children completed CPET examination safely without experiencing serious circulation abnormalities. Compared with the SV group, the VO2/kg max ((32.6±6.9) ml·kg-1·min-1 vs. (23.5±5.9) ml·kg-1·min-1, P<0.001), O2/HR max ((7.24±2.93) ml/beat vs. (6.35±2.17)ml/beat, P=0.030), HRR at 1 min ((32.5±13.9) beat/min vs. (26.3±12.5) beat/min, P=0.036), OUES/kg (36.9±8.8 vs. 29.7±11.8, P=0.001) were significantly higher, VE/VCO2 slope (29.1±5.20 vs. 35.1±8.0, P<0.001) and incidence of EOV (32.0%(24/75) vs. 57.4%(31/61), P=0.027) were significantly lower in BV group. Compared with the simple CHD subgroup, VE/VCO2 slope and the incidence of EOV were higher, VO2/kg max, O2/HR max, HRR at 1 min and OUES/kg were lower in the complex CHD subgroup (all P<0.05). Cardiopulmonary function parameters of the BV group were lower than the normal value. Linear correlation analysis showed that VO2/kg@AT was strongly correlated with VO2/kg max (r=0.86, P<0.001), VO2/kg max was strongly correlated with OUES/kg (r=0.63, P<0.001), HRR was strongly correlated with CI (r=0.91, P<0.001), and VO2/kg max was strongly correlated with OUES/kg (r=0.63, P<0.001). VE/VCO2 slope was strongly correlated with PetCO2 max (r=1.00, P<0.001). Conclusions: The exercise cardiopulmonary function of children after single ventricular correction is weaker than that of biventricular correction, and the exercise tolerance of children after biventricular correction is lower than that of normal children. Among the children after biventricular correction, the exercise tolerance of children with complex CHD is lower than that of children with simple CHD. Postoperative CPET is of important realistic significance for CHD children.

Abstract
Acute carbon monoxide poisoning can cause multiple organ damage due to hypoxia. In severe cases, it can be life-threatening and has a high fatality rate. Intestinal obstruction and thrombosis are rare complications of carbon monoxide poisoning. A case of carbon monoxide poisoning was reported. In addition to the central nervous system lesion, intestinal obstruction and lower limb thrombosis were also found. In the treatment of carbon monoxide poisoning patients, the clinician was able to treat the common complications, attention should be paid to gastrointestinal tract, thrombotic disease and other rare complications, so as to avoid missed diagnosis.

Abstract
Plumes have been identified as an access region for chorus waves to enter the plasmasphere. Here, for the first time, chorus wave properties are parameterized by distance from the plume boundary. Case studies and statistical analysis indicate that the polar wave vector angle, θ k , of chorus becomes more oblique near the plume edge. Occurrence rates of θ k > 35° on the plume boundary are approximately double that observed further away from the plume. Whilst the increase in θ k is apparent on both plume edges, the distribution of θ k exhibits different behavior between the Eastward and Westward boundaries. In general, the distribution of azimuthal wave vector angles, ϕ k , is symmetric about the anti-Earthwards direction. However, near the Eastward plume boundary, an Eastwards skew of ϕ k is reported. This result provides new insight on chorus propagation in the context of the chorus-to-hiss mechanism, and has implications for quantifying wave-particle interactions in the near-plume region.

Abstract
BACKGROUND The association between strength, assistance with walking, rise from a chair, climb stairs and falls (SARC-F), strength, assistance with walking, rise from a chair, climb stairs, falls and calf circumference (SARC-CalF), Ishii score chart, the short version of mini sarcopenia risk assessment (MSRA-5), the full version of mini sarcopenia risk assessment (MSRA-7) and clinical outcomes in patients with gastric cancer were unclear. We aimed to investigate the predictive values of the above five sarcopenia screening tools on clinical outcomes following surgery in patients with gastric cancer. METHODS The clinical data of consecutive patients who would undergo gastrectomy from May 2020 to October 2020 at the First Affiliated Hospital of Nanjing Medical University were prospectively collected. On the first admission day, patients' characteristics, Nutrition risk screening 2002 (NRS 2002), the above five sarcopenia screening tools and anthropometric measurements were preoperatively collected. Within 24 hours after discharge, operation information, tumor-node-metastasis (TNM) stage and clinical outcomes in hospital (postoperative complications, hospitalization expenditures and postoperative hospital stay) were collected. Three months after discharge, clinical outcomes out of hospital (hospital readmissions and mortality) were collected. Multivariate analyses were conducted to identify the independent predictors for clinical outcomes. RESULTS A total of 263 patients were finally included in the study, with the average age being 62.44 years. The prevalence of sarcopenia risk ranged from 3.42% to 73.76%. For the above five sarcopenia screening tools, multivariate analyses showed that sarcopenia risk indicated by SARC-CalF was an independent predictor for postoperative complications (OR=3.145 [95%CI: 0.594, 16.665], P=0.037), prolonged postoperative hospital stay (B=2.383 [95%CI: 0.377, 4.388], P=0.020), increased hospitalization expenditures (B=1.305 [95%CI: 0.402, 2.208], P=0.005) and 3-month hospital readmissions (HR=3.626 [95%CI: 1.126, 11.676], P=0.031). Sarcopenia risk indicated by Ishii score chart was an independent predictor for postoperative complications (OR=6.491 [95%CI: 1.514, 27.840], P=0.012) and hospitalization expenditures (B=0.767 [95%CI: 0.065, 1.469], P=0.032). Sarcopenia risk indicated by MSRA-7 was an independent predictor for prolonged postoperative hospital stay (B=1.636 [95%CI: 0.119, 3.153], P=0.035)and increased hospitalization expenditures (B=0.831 [95%CI: 0.146, 1.516], P=0.018). CONCLUSION Among the above five sarcopenia screening tools, SARC-CalF seemed to have better predictive values on clinical outcomes. Preoperative gastric cancer patients with sarcopenia risk indicated by SARC-CalF could have a higher risk of postoperative complications, prolonged postoperative hospital stay, increased hospitalization expenditures and 3-month hospital readmissions.

Abstract
Objective: To translate the food allergy quality of life-parental burden (FAQL-PB) scale into Chinese and test its reliability and validity among the caregivers of children with food allergy. Methods: The caregivers of 222 children with food allergy were enrolled by convenient sampling from October 2020 to October 2021 in the Children's Hospital Affiliated to Chongqing Medical University. The forward-backward translation and cultural adaptation of the original FAQL-PB scale was performed in accordance with Brislin's model. Item analysis was used to select items. The validity of the questionnaire was analyzed with the item-level content validity and the exploratory factors analysis. And the internal consistency coefficient, split-half reliability and test-retest reliability were used to evaluate the reliability of the questionnaire. Results: The Pearson correlation coefficients of the scores between each item and total scale ranged from 0.72 to 0.88 (P<0.01). The item-level content validity index (I-CVI) ranged from 0.83 to 1.00, scale-level content validity index/universal agreement (S-CVI/UA) was 0.94, and scale-level content validity index/average (S-CVI/Ave) was 0.99. Exploratory factor analysis revealed that Chinese version of FAQL-PB scale could be classified into two dimensions: emotional distress and limitations on life, with the accumulative variance contribution rate of 74.08%. The Cronbach's α coefficient, split-half reliability coefficient and test-retest reliability of the Chinese version of FAQL-PB scale were 0.97, 0.98 and 0.71, respectively. Conclusion: The Chinese version of FAQL-PB scale is proved to be reliable and eligible, and can be used as a specific tool to investigate the quality of life in family of children with food hypersensitivity.

Abstract
To determine denosumab's effectiveness for fracture prevention among postmenopausal women with osteoporosis in East Asia, the risk of fracture was compared between patients continuing denosumab therapy versus patients discontinuing denosumab after one dose. The real-world effectiveness was observed to be consistent with the efficacy demonstrated in the phase III trial. INTRODUCTION After therapeutic efficacy is demonstrated for subjects in global clinical trials, real-world evidence may provide complementary knowledge of therapeutic effectiveness in a heterogeneous mix of patients seen in clinical practice. This retrospective cohort study was conducted to compare the fracture risk in real-world clinical care received in Taiwan and Hong Kong between a treatment cohort (patients receiving denosumab 60 mg subcutaneously every 6 months) versus an off-treatment cohort (patients discontinuing after 1 dose of denosumab, which has no known clinical benefit) among real-world postmenopausal women. METHODS This study included 38,906 and 2,835 postmenopausal women receiving denosumab in Taiwan and Hong Kong, respectively. The primary endpoint was hip fracture, and secondary endpoints were clinical vertebral and nonvertebral fractures. Propensity-score-matched analysis, adjusting for known covariates, was used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs). The robustness of findings was evaluated with a series of sensitivity and quantitative bias analyses. RESULTS In this study, 554 hip fractures were included in the primary Taiwan population analysis. The crude incidence rate was 0.9 per 100 person-years in the treatment cohort (n = 25,059) and 1.7 per 100 person-years in the off-treatment cohort (n = 13,847). After adjusting for prognostic differences between cohorts, denosumab reduced the risk of hip fractures by 38% (HR = 0.62, CI:0.52-0.75). Risk reductions of similar magnitude were observed for the secondary endpoints and for the analysis of the smaller Hong Kong population. CONCLUSION The effectiveness of denosumab for fracture reduction among real-world postmenopausal women with osteoporosis was consistent with the efficacy demonstrated in a global clinical trial.

Abstract
OBJECTIVE Osteoarthritis (OA) is an age-related degenerative disease accompanied by an increasing number of senescent cells and chronic low-grade inflammation. Rhoifolin (ROF) showed considerable inhibition to inflammation, but its role in chondrocyte senescence and OA progress has not been fully characterized. We aimed to evaluate the protective effects of ROF on OA through a series of in vitro and in vivo experiments. METHODS The role of ROF in the expression of senescence-associated secretory phenotype (SASP) factors was investigated using RT-qPCR, western blotting, and ELISA. Chondrocyte senescence was assessed by SA-β-gal staining. We applied molecular docking to screen candidate proteins regulated by ROF. Meanwhile, SASP factors and cellular senescence were further assessed after the transfection of Nrf2 siRNA. In the anterior cruciate ligament transection (ACLT) rat model, X-ray, hematoxylin-eosin (HE), and Masson's staining were performed to evaluate the therapeutic effects of ROF on OA. RESULTS We found that ROF inhibited SASP factors expression and senescence phenotype in IL-1β-treated chondrocytes. Furthermore, ROF suppressed IL-1β-induced activation of the NF-κB pathway cascades. Also, molecular docking and knock-down studies demonstrated that ROF might bind to Nrf2 to suppress the NF-κB pathway. In vivo, ROF ameliorated the OA process in the ACLT rat model. CONCLUSIONS ROF inhibits SASP factors expression and senescence phenotype in chondrocytes and ameliorates the progression of OA via the Nrf2/NF-κB axis, which supports ROF as a potential therapeutic agent for the treatment of OA.

Abstract
Objective: To investigate the clinical effects of free transplantation of expanded ilioinguinal flaps in the reconstruction of severe scar contracture after extensive burns. Methods: A retrospective observational study was conducted. From August 2017 to October 2021, 7 patients with severe scar contracture deformity caused by extensive burns were hospitalized in Tongren Hospital of Wuhan University & Wuhan Third Hospital, including 5 males and 2 females, aged 26-65 years, with scar area of 20 cm×4 cm-34 cm×14 cm. In the first stage, the rectangular skin and soft tissue expander (hereinafter referred to as the expander) with rated capacity of 500-600 mL were embedded above the inguinal ligament, and then normal saline was injected after stitch removal for expansion to meet the needs of repair surgery. In the second stage, the scar was removed by surgical excision to correct the deformity and release the adhesion and contracture; after the removal of the expanders, the expanded ilioinguinal free flaps were harvested. When a larger flap was needed, the paraumbilical perforator flap was harvested at the same time, and the flaps were transplanted to the secondary wound after scar resection. The number of embedded expanders, the total amount of injected normal saline, the expansion time, the complications of skin and soft tissue expansion, the number, area, thickness, and anastomotic vascular pedicles of the expanded ilioinguinal flaps being resected, the type of flaps used, the repair method of flap donor sites, and the survival of flaps after operation were observed and recorded. The long-term repair effect and donor site condition were followed up. At the last follow-up, the patients' satisfaction with the curative effect of each surgical site was investigated according to the grade 5 score of Likert scale. Results: A total of 10 expanders were embedded in 7 patients, of which 4 patients had 1 each and 3 patients had 2 each. The total volume of normal saline injected was 800-1 800 (1 342±385) mL, and the expansion time was 4-24 (11±5) months. One patient had the expander exposed due to infection after the expander being inserted, while the other patients had no complications of skin and soft tissue expansion. Totally 10 expanded ilioinguinal flaps with the area of 22 cm×6 cm-36 cm×16 cm ((326±132) cm2) and the thickness of 0.6-1.1 (0.77±0.16) cm were harvested. Among the 10 expanded ilioinguinal flaps, 5 were pedicled with the superficial circumflex iliac artery, 3 with the superficial abdominal artery with relatively large caliber, 1 with the common trunk of the superficial circumflex iliac artery and the superficial abdominal artery, and 1 flap was anastomosed with the superficial circumflex iliac artery and bridged the superficial abdominal artery for intra-arterial supercharge. Unilateral expanded ilioinguinal flap combined with ipsilateral paraumbilical perforator flap were harvested in 4 cases, bilateral expanded ilioinguinal flaps were harvested in 1 case, and unilateral expanded ilioinguinal flap was harvested in 2 cases. Except for 1 case being transplanted with autologous split-thickness scalp to repair the flap donor site after combined resection of bilateral expanded ilioinguinal flaps, the donor sites of the other patients were sutured directly. All the flaps survived after operation without tip necrosis or wound residue. Follow-up for 3-30 (15±10) months showed that the flap was soft and not bloated, the function and appearance of the recipient area were significantly improved compared with those before operation, and the appearance of the donor sites was good. At the last follow-up, the patients' satisfaction with the treatment effect of the surgical site scored 4-5 (4.5±0.4). Conclusions: The expanded ilioinguinal flap can be obtained in a large area. It has the advantages of rich blood supply, less damage to the donor site, concealed location, and being convenient to be resected and transplanted in combination with the paraumbilical perforator flap. It is suitable for the clinical reconstruction and treatment of severe scar contracture deformity after extensive burns.

Abstract
The gut microbiome is associated with diverse diseases1-3, but a universal signature of a healthy or unhealthy microbiome has not been identified, and there is a need to understand how genetics, exposome, lifestyle and diet shape the microbiome in health and disease. Here we profiled bacterial composition, function, antibiotic resistance and virulence factors in the gut microbiomes of 8,208 Dutch individuals from a three-generational cohort comprising 2,756 families. We correlated these to 241 host and environmental factors, including physical and mental health, use of medication, diet, socioeconomic factors and childhood and current exposome. We identify that the microbiome is shaped primarily by the environment and cohabitation. Only around 6.6% of taxa are heritable, whereas the variance of around 48.6% of taxa is significantly explained by cohabitation. By identifying 2,856 associations between the microbiome and health, we find that seemingly unrelated diseases share a common microbiome signature that is independent of comorbidities. Furthermore, we identify 7,519 associations between microbiome features and diet, socioeconomics and early life and current exposome, with numerous early-life and current factors being significantly associated with microbiome function and composition. Overall, this study provides a comprehensive overview of gut microbiome and the underlying impact of heritability and exposures that will facilitate future development of microbiome-targeted therapies.

Abstract
Objective: To evaluate the pink and white esthetics of conventional and socket shield technique (SST) immediate implant restoration. Methods: Thirty volunteers were recruited according to preset criteria, and were assigned to 3 groups. Natural teeth group (ten undergraduates or postgraduates from Peking University School and Hospital of Stomatology in January 2020, n=10): all volunteers' maxillary anterior teeth were natural teeth with healthy gingiva, and none of the teeth were restored by crowns or composite. Conventional group and SST group (patients had a maxillary central incisor immediate implant placed in Department of Prosthodontics, Peking University School and Hospital of Stomatology during October 2016 to January 2021, n=10 for each group): the volunteer had an unrestored natural maxillary central incisor, and the contralateral maxillary central incisor was restored by conventional or SST immediate implant placement, temporization and all ceramic final restoration, photos were taken 12 months post-surgery. Three groups of evaluators namely layperson (staff from Second Clinical Division of Peking University School and Hospital of Stomatology and 2 family members, n=10), dental students (class 2015 undergraduates from Peking University School and Hospital of Stomatology, n=10) and prosthodontists (from Department of Prosthodontics, Peking University School and Hospital of Stomatology, n=10) were invited to assess the esthetics using pink esthetic score (PES) and white esthetic score (WES). The results were statistically analyzed. Results: PES and WES of natural teeth group [9(8, 10) and 8(7, 10)] were significantly higher than conventional group [7(6,8) and 7(6,9)] (H=287.08, 132.79,P<0.01) and SST group [7(6, 9) and 8(7, 9)] (H=216.01, 101.21, P<0.01). SST group yielded higher PES than the conventional group (H=-71.06, P<0.01), yet had similar WES (H=-31.57, P>0.05). Dental students had significant lower PES and WES than prosthodontists (H=-120.90, -218.86, P<0.01) and layperson (H=-109.55, 134.97, P<0.01). Prosthodontists and layperson got similar PES (H=-11.36, P>0.05), however yielded different WES (H=-83.89, P<0.01). Conclusions: SST immediate implant placement obtained better pink esthetics than conventional protocol 12-month after implant surgery, profession may have significant impact on evaluators during pink and white esthetic evaluation.
