Patient self-reported experience and satisfaction with golimumab and etanercept treatments for rheumatic diseases: A cohort study.

Golimumab and etanercept both exhibit good efficacy in treating rheumatic diseases, while the patient self-reported measurement of treatment improvement and injection experience lacks sufficient evidence. Hence, this study aimed to compare the satisfaction with disease improvement and injection experience and the level of injection site reactions (ISRs) between golimumab-treated and etanercept-treated patients with rheumatic diseases. A total of 312 patients with rheumatic diseases were serially enrolled. Among them, 158 patients received golimumab (golimumab group); the other 154 patients were treated with etanercept (etanercept group) according to the actual disease status, physician advice, and patient willingness. Satisfaction with disease improvement was assessed using the 7-point Likert scale; satisfaction with injection experience and level of ISRs were both determined by the 5-point Likert scale. Satisfaction degrees with global injection experience (P = .025), injection device (P = .008), injection frequency (P = .010), and injection convenience (P = .003) were superior in the golimumab group to the etanercept group, while satisfaction degrees with global disease improvement, symptom relief, and speed of action did not vary (all P > .050) between the 2 groups. Discomfort (P = .005), swelling (P < .001), pain (P = .028), and burning (P = .035) levels were lower in the golimumab group than in the etanercept group. In addition, among 56 patients with a history of tumor necrosis factor inhibitor treatment before golimumab, 40 (71.4%) patients preferred golimumab to other tumor necrosis factor inhibitor. After switching to golimumab treatment, the level of ISRs in most patients was reduced or comparable. Golimumab achieves a satisfying injection experience and relieves the level of ISRs over etanercept in patients with rheumatic diseases.

Risk factors of cervical cancer among ethnic minorities in Yunnan Province, China: a case-control study.

BACKGROUND: Cervical cancer is a common malignant tumor of the female reproductive system in the world, which is a serious threat to women's life and health. According to the latest report, the incidence of cervical cancer is 11.42 per 100 000, and the mortality rate is 3.77 per 100 000 in Yunnan Province, which is still higher than the national average. Although there have been some relevant studies on the risk factors of cervical cancer in recent years, research on ethnic minorities is lacking in Yunnan Province. OBJECTIVE: To analyze and explore the related risk factors of cervical cancer in women of ethnic minorities in Yunnan Province, to provide the scientific basis for the development of cervical cancer prevention and control strategies and measures in this region. METHODS: In total 1119 cervical cancer patients diagnosed by histopathology at the Yunnan Cancer Center (Yunnan Cancer Hospital) from January 2010 to December 2019 were selected as the case group. According to the 1:1 matching principle of the case-control study, 1119 patients with nonmalignant tumors of the same nationality, the same hospital, age difference less than 3 years old, were selected as the control group. Univariate and multivariate conditional logistic regression were used for statistical analysis. RESULTS: Basic medical insurance for rural residents (OR = 3.659; P = 0.003), human papilloma virus (HPV) infection (OR = 90.030; P < 0.001) and concurrent reproductive tract infections (OR = 1.992; P = 0.047) were risk factors for cervical cancer. Late first marriage(OR = 0.881; P = 0.032), the number of normal childbirths ≤2 (OR = 0.480, P = 0.033) and contraception (OR = 0.291; P = 0.002) were positive factors for cervical cancer. CONCLUSION: The high incidence of cervical cancer in Yunnan minority women is the result of many factors: HPV infection is the highest risk factor for cervical cancer, women with reproductive tract infections and basic medical insurance for rural residents have a higher risk for cervical cancer; Late first marriage, the number of deliveries ≤2 and contraception are positive factors for cervical cancer.

Multiple intravenous tranexamic acid doses in total knee arthroplasty in patients with rheumatoid arthritis: a randomized controlled study.

BACKGROUND: We aimed to determine the efficacy and safety of multiple doses of intravenous tranexamic acid (IV-TXA) on perioperative blood loss in patients with rheumatoid arthritis (RA) who had undergone primary unilateral total knee arthroplasty (TKA). METHODS: For this single-center, single-blind randomized controlled clinical trial, 10 male and 87 female participants with RA, aged 50-75 years, who underwent unilateral primary TKA were recruited. The patients received one dose of 1 g IV-TXA 10 min before skin incision, followed by articular injection of 1.5 g tranexamic acid after cavity suture during the surgery. The patients were randomly assigned (1:1) into two groups and received an additional single dose of IV-TXA (1 g) for 3 h (group A) or three doses of IV-TXA (1 g) for 3, 6, and 12 h (group B) postoperatively. Primary outcomes were total blood loss (TBL), hidden blood loss (HBL), and maximum hemoglobin (Hb) level decrease. Secondary outcomes were transfusion rate and D-dimer levels. All parameters were measured postoperatively during inpatient hospital stay. RESULTS: The mean TBL, HBL, and maximum Hb level decrease in group B (506.1 ± 227.0 mL, 471.6 ± 224.0 mL, and 17.5 ± 7.7 g/L, respectively) were significantly lower than those in group A (608.8 ± 244.8 mL, P = 0.035; 574.0 ± 242.3 mL, P = 0.033; and 23.42 ± 9.2 g/L, P = 0.001, respectively). No episode of transfusion occurred. The D-dimer level was lower in group B than in group A on postoperative day 1 (P <  0.001), and the incidence of thromboembolic events was similar between the groups (P > 0.05). CONCLUSION: In patients with RA, three doses of postoperative IV-TXA further facilitated HBL and Hb level decrease without increasing the incidence of adverse events in a short period after TKA. TRIAL REGISTRATION: The trial was registered in the Chinese Clinical Trial Registry ( ChiCTR1900025013 ).

Effect of Multiple Doses of Intravenous Tranexamic Acid on Perioperative Blood Loss in Total Knee Arthroplasty: A Randomized Controlled Study.

OBJECTIVE: To identify the efficacy and safety of multiple doses of intravenous tranexamic acid (IV-TXA) following primary total knee arthroplasty (TKA) with a tourniquet. METHODS: This is a single-blind randomized controlled study that recruited osteoarthritis patients who had undergone primary unilateral TKA from May 2019 to May 2020 at our medical center. A total of 300 patients were randomly divided into three groups to receive: one dose (1 g) of IV-TXA before skin incision combined with one dose (1.5 g) of intra-articular tranexamic acid（IA-TXA) followed by a single dose of IV-TXA (1 g) for 3 h (group A); two doses of IV-TXA (1 g) for 3 and 6 h (group B); or three doses of IV-TXA (1 g) for 3, 6, and 12 h (group C) postoperatively. TKA with a tourniquet was performed by the same surgical team. The primary outcomes were total blood cell loss (TBL), hidden blood loss (HBL), maximum hemoglobin (Hb) drop, and transfusion rate. Secondary outcomes were levels of C-reactive protein (CRP) and D-dimer, and the incidence of postoperative complications. One-way analysis of variance, subgroup analysis, and multivariate correlation analysis were used to calculate the differences among the three groups. RESULTS: The study included 56 male and 244 female patients aged 60-80 years. The mean TBL, the mean HBL, and the maximum Hb drop in group C (471.2 ± 190.6 mL, 428.4 ± 190.3 mL, and 21.2 ± 3.8 g/L, respectively) were significantly lower than those in groups B (563.4 ± 224.6 mL, P = 0.030; 519.9 ± 226.4 mL, P = 0.033; and 23.2 ± 4.1 g/L, P = 0.001, respectively), and A (651.6 ± 254.1 mL, P < 0.001; 607.1 ± 254.3 mL, P < 0.001; and 25.1 ± 4.3 g/L, P < 0.001, respectively). No transfusions were required. The postoperative acute inflammatory reaction was less problematic for patients in Group C, and the incidence of thromboembolic events was similar among the groups (P > 0.05). In addition, there were positive correlations between the HBL and the tourniquet inflation time (r = 0.844, P < 0.001). Similarly, the level of CRP on POD1 (r = 0.393, P < 0.001) and POD3 (r = 0.149, P = 0.010), and the level of D-dimer on POD1 (r = 0.382, P < 0.001) were positively correlated with the HBL. CONCLUSION: Three doses of postoperative IV-TXA decreased blood loss and diminished the postoperative inflammatory and fibrinolytic response more than a single dose or two doses in elderly patients following TKA without increasing the incidence of adverse events.

Using electroacupuncture to recover muscle strength in patients with knee osteoarthritis after total knee arthroplasty: a study protocol for a double-blinded, randomized, and placebo-controlled trial.

BACKGROUND: Total knee arthroplasty (TKA) is a gold standard for patients with terminal term gonarthrosis for reducing pain, correcting deformities, and regaining stability. However, post-TKA muscle strength recovery is often difficult. Although electroacupuncture (EA) enhances lower extremity muscle strength of the lower extremity, there is limited evidence regarding its effect on lower extremity muscle strength in post-TKA patients. Consequently, this trial intends to evaluate the efficacy of post-TKA EA on the recovery of lower extremity muscle strength, specifically, during the early post-TKA period. METHODS/DESIGN: This is a double-blinded, randomized, and controlled trial. It will be conducted between August 2020 and December 2020. Ninety-four participants with KOA who have undergone unilateral TKA will be randomized into a treatment (EA) group and a control (sham EA) group. The former and latter groups will receive EA and sham EA, respectively, at ST37, ST36, SP10, and SP9 acupoints. The participants will undergo ten treatment sessions over 2 weeks (5 sessions per week). The primary outcomes will include changes in muscle strength and the Hospital for Special Surgery score at the second week from baseline (pre-op 1 day or POD 3). The secondary outcomes will include a 4-m walk test, numerical rating scale score, the Hamilton Anxiety Scale score, and additional analgesia use. Additional outcomes will include the incidence of analgesia-related side effects and the participant satisfaction rate. Participant blinding will also be assessed where they will be asked to guess whether they received EA after the latest intervention. Adverse EA events will be documented and assessed throughout the trial. DISCUSSION: EA is helpful for post-TKA recovery and enhancement of lower limb muscle strength.

Cyr61 participates in the pathogenesis of rheumatoid arthritis via promoting MMP-3 expression by fibroblast-like synoviocytes.

OBJECTIVES: The aim of this study was to investigate the effect and potential mechanism of Cysteine-rich 61 (Cyr61) on stimulating MMP-3 expression by fibroblast-like synoviocytes (FLS) from rheumatoid arthritis (RA) patients. METHODS: Primarily cultured RA FLS were treated with exogenous Cyr61 protein or Cyr61-siRNA, then, MMP-3 expression was analyzed by real-time PCR, western blotting and ELISA. Signal transduction pathways in Cyr61-induced MMP-3 production were examined by real-time PCR, western blotting, confocal microscopy, luciferase reporter assay. Mice with collagen-induced arthritis (CIA) were treated with anti-Cyr61 monoclonal antibodies (mAb), or IgG1 as control and MMP-3 in the joint was detected by IHC, real-time PCR and western blotting. RESULTS: High expressed MMP-3 and Cyr61 were positively correlated in RA ST; Cyr61 stimulated MMP-3 production in FLS of RA patients in an IL-1ß and TNF-α independent manner. Cyr61 induced MMP-3 could further enhance the invasive ability of RA FLS. Mechanistically, we found that Cyr61 promoted MMP-3 production via the P38, JNK-dependent AP-1 signaling pathway. Blockage of Cyr61 function with monoclonal antibody could decrease MMP-3 expression in the joints of CIA mice. CONCLUSION: This study provides new evidence that Cyr61 participates in RA pathogenesis not only as a pro-inflammatory factor but also plays a key role in bone erosion via promoting MMP-3 expression. We suggest that targeting of Cyr61 may represent a potential strategy in RA treatment.
