Osteoarthritis Cartilage 2021; 29:697-706. [PMID: 33621706 DOI: 10.1016/j.joca.2021.02.382] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/18/2020] [Revised: 02/03/2021] [Accepted: 02/07/2021] [Indexed: 02/02/2023]
Abstract
OBJECTIVE Smoking represents a major issue for global public health. Owing to methodologic challenges, findings of an association between smoking and risk of knee osteoarthritis (OA) are inconsistent. We sought to assess the relation of onset of smoking cessation to the risk of OA sequelae, i.e., knee replacement, and to perform sub-cohort analysis according to weight change after smoking cessation. DESIGN Using The Health Improvement Network, we conducted a cohort study to examine the association between smoking cessation and risk of knee replacement among patients with knee OA. Participants who stopped smoking were further grouped into three sub-cohorts: weight gain (body mass index [BMI] increased>1.14 kg/m2), no substantial weight change (absolute value of BMI change<1.14 kg/m2), and weight loss (BMI loss>1.14 kg/m2) after smoking cessation. RESULTS We identified 108 cases of knee replacement among 1,054 recent quitters (26.7/1,000 person-years) and 1,108 cases among 15,765 current smokers (17.4/1,000 person-years). The rate difference of knee replacement in recent quitter cohort vs current smoker cohort was 10.4 (95% confidence interval [CI]:5.3-15.6)/1,000 person-years and the adjusted hazard ratio (HR) was 1.30 (95%CI:1.05-1.59). Compared with current smokers, risk of knee replacement was higher among quitters with weight gain (HR = 1.42,95%CI:1.01-1.98), but not among those with no substantial weight change (HR = 1.29,95%CI:0.90-1.83) or those with weight loss (HR = 1.11,95%CI:0.71-1.75). CONCLUSIONS Our large population-based cohort study provides the first evidence that smoking cessation was associated with a higher risk of knee replacement among individuals with knee OA, and such an association was due to weight gain after smoking cessation.

Abstract
OBJECTIVE To explore the expression pattern and clinical significance of circ_0000515 in hepatocellular carcinoma (HCC), as well as the molecular mechanism. PATIENTS AND METHODS Fifty HCC patients were recruited, and their cancer tissues and adjacent normal ones were collected for detecting the differential expression of circ_0000515. The relationship between circ_0000515 and clinical parameters in HCC patients was analyzed. Circ_0000515 knockdown model was generated by lentivirus transfection in Hep3B and MHCC88H cells that were highly expressed with circ_0000515. Regulatory effects of circ_0000515 on phenotypes of Hep3B and MHCC88H cells were examined by Cell Counting Kit-8 (CCK-8) and transwell assay. Target gene of circ_0000515 was verified by Dual-Luciferase reporter assay, and its involvement in HCC progression was detected by rescue experiments. In vivo xenograft model was generated in nude mice aiming to elucidate the role of circ_0000515 in regulating HCC growth. RESULTS Circ_0000515 was highly expressed in HCC tissues and cell lines. High level of circ_0000515 predicted advanced stage, high incidence of lymphatic metastasis, and low disease-free survival and overall survival in HCC. Knockdown of circ_0000515 attenuated proliferative and migratory abilities in Hep3B and MHCC88H cells. MAPK10, as the target gene binding circ_0000515, was negatively regulated by circ_0000515. Rescue experiments and in vivo xenograft model both indicated that circ_0000515 aggravated the malignant progression of HCC by targeting MAPK10. CONCLUSIONS Circ_0000515 is upregulated in HCC tissues and cell lines. It can be used for predicting tumor staging, lymphatic metastasis, and prognosis in HCC. Circ_0000515 aggravates the malignant progression of HCC by downregulating MAPK10.

Abstract
Experimental studies of the simultaneous acceleration of three-charge-state ^{129}Xe^{49+,50+,51+} beam from 17 to 180 MeV/nucleon in a superconducting linear accelerator are presented. The beam parameters for each individual- and multiple-charge-state beam were measured and compared with the particle tracking simulations. Detailed measurements were performed to characterize the multiple-charge-state beam's recombination after a second-order achromat and isopath 180° bending system. As a result of the recombination of three charge states in the six-dimensional phase space, the xenon beam intensity was increased by 2.5-fold compared to the single-charge-state beam. The results presented in the Letter fully validate the possibility to produce and utilize high-quality multiple-charge-state heavy-ion beams in a large-scale superconducting linac to increase the available beam power on an isotope production target.

Lower-dose decitabine improves clinical response compared with best supportive care in lower-risk MDS patients: a prospective, multicenter phase 2 study. J Cancer 2021; 12:2975-2981. [PMID: 33854598 PMCID: PMC8040893 DOI: 10.7150/jca.56207] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/20/2020] [Accepted: 03/04/2021] [Indexed: 11/06/2022] Open
Abstract
Purpose: To explore the efficacy and safety of lower-dose decitabine in patients with lower-risk MDS, a prospective multicenter phase II study was conducted to compare decitabine with the best supportive care (BSC). Methods: Patients diagnosed with lower-risk MDS from September 2013 to August 2018 were assigned to the decitabine group or the BSC group. Decitabine (12 mg/m2/day) was administered over 1 hour/day for 5 consecutive days in a 4-week cycle. BSC, including growth factors, transfusion, thalidomide, lenalidomide, and immunosuppressive agents were given consecutively. The endpoints included the proportion of patients who achieved overall response (OR) in the first 2 or 3 courses, event-free survival (EFS), and overall survival (OS). Results: A total of recruited 82 patients were analyzed. In the decitabine group, 65.9% (27/41) achieved OR after 2 or 3 cycles of treatment, compared with 22.0% (9/41) in the BSC group (p <0.01). Besides, 44.0% (11/25) in the decitabine group became independent of RBC/Platelets transfusion, compared with 27.8% (5/18) in the BSC group. Patients with gene mutation and treated with decitabine achieved a higher OR rate, compared with those without gene mutation [72.0% (18/25) vs 11.5% (3/26), p <0.01]. There was no significant difference in the median EFS between the decitabine and BSC groups (20.6 vs 14.3 months respectively, p = 0.665). In the decitabine group, the most significant adverse events were infections of any grades or neutropenic fever (46.3%, 19/41) and one patient (4.2%) died of acute cerebral infarction within 6 weeks of treatment. Conclusion: Lower-dose decitabine demonstrated promising clinical response with acceptable toxicity profiles in patients with low- and intermediate 1-risk MDS. A higher response rate to decitabine was observed in patients with mutated genes. Therefore, lower-dose decitabine can be advocated for patients with low-risk MDS and mutated genes.

Abstract
Precise knowledge of the charge and rigidity dependence of the secondary cosmic ray fluxes and the secondary-to-primary flux ratios is essential in the understanding of cosmic ray propagation. We report the properties of heavy secondary cosmic ray fluorine F in the rigidity R range 2.15 GV to 2.9 TV based on 0.29 million events collected by the Alpha Magnetic Spectrometer experiment on the International Space Station. The fluorine spectrum deviates from a single power law above 200 GV. The heavier secondary-to-primary F/Si flux ratio rigidity dependence is distinctly different from the lighter B/O (or B/C) rigidity dependence. In particular, above 10 GV, the F/Si/B/O ratio can be described by a power law R^{δ} with δ=0.052±0.007. This shows that the propagation properties of heavy cosmic rays, from F to Si, are different from those of light cosmic rays, from He to O, and that the secondary cosmic rays have two classes.

Abstract
OBJECTIVE Atherosclerosis (AS) is a representative inflammatory vascular disease. This study explored the molecular pathogenesis of AS based on circular RNA (circRNA), the checkpoint with forkhead-associated and ring-finger domains (circ_CHFR). PATIENTS AND METHODS The cell model of AS in vitro was established by stimulating human vascular smooth muscle cells (VSMCs) with oxidized low-density lipoprotein (ox-LDL). The RNA expression was measured by quantitative Real-time polymerase chain reaction (qRT-PCR). Cell viability and colony formation ability were separately evaluated using 3-(4, 5-dimethylthiazol-2-y1)-2, 5-diphenyl tetrazolium bromide (MTT) and colony formation assay. Cell migration was assessed via the transwell assay. The inflammation injury was analyzed by enzyme-linked immunosorbent assay (ELISA). Associated proteins were determined through Western blot. The combination of hypothetic targets was ascertained using Dual-Luciferase reporter assay. RESULTS Circ_CHFR was up-regulated in AS serums and ox-LDL-stimulated VSMCs. Circ_CHFR depletion weakened the ox-LDL-induced promotion of cell growth, migration and inflammation in VSMCs. Circ_CHFR positively regulated Wnt3 expression and the downregulation of Wnt3 abrogated the ox-LDL-triggered injuries in VSMCs. Circ_CHFR functioned as the sponge of microRNA-214-3p (miR-214-3p) and miR-214-3p targeted Wnt3. Circ_CHFR regulated cell growth, migration and inflammation via regulating the expression of Wnt3 as a competitive endogenous RNA (ceRNA) of miR-214 in ox-LDL-treated VSMCs. Circ_CHFR/miR-214-3p axis mediated the Wnt3/β-catenin signal pathway. CONCLUSIONS Circ_CHFR contributed to the progression of AS through the miR-214-3p/Wnt3/β-catenin signals, which illuminated the molecular mechanism of AS and suggested circ_CHFR might be an index for AS treatment.

Abstract
We report the observation of new properties of primary iron (Fe) cosmic rays in the rigidity range 2.65 GV to 3.0 TV with 0.62×10^{6} iron nuclei collected by the Alpha Magnetic Spectrometer experiment on the International Space Station. Above 80.5 GV the rigidity dependence of the cosmic ray Fe flux is identical to the rigidity dependence of the primary cosmic ray He, C, and O fluxes, with the Fe/O flux ratio being constant at 0.155±0.006. This shows that unexpectedly Fe and He, C, and O belong to the same class of primary cosmic rays which is different from the primary cosmic rays Ne, Mg, and Si class.

Abstract
BACKGROUND Diffuse large B-cell lymphoma (DLBCL) patients refractory to rituximab-based immunochemotherapy have a dismal prognosis. However, the definition of refractory DLBCL remains inconsistent and no large cohort study data is available from Asian countries. To validate the definition and outcomes of refractory DLBCL in China, we conducted a multicenter, retrospective cohort study. METHODS The REtrospective AnaLysis of Treatment REspoNse of refractory DLBCL (REAL-TREND) study was performed using real-world data from 8 centers in China. DLBCL patients with curative intent were included in the REAL-TREND dataset. Overall survival (OS) was estimated using the Kaplan-Meier method and compared by the log-rank test. Due to heterogeneity in response rates among different centers, the response rates of refractory patients were pooled using random-effect models. Multivariate survival analysis was performed using the Cox regression model. RESULTS A total of 2778 DLBCL patients diagnosed between January, 2010 and December, 2015 were enrolled to this study. After validating previous definitions, the SCHOLAR-1 study was most suitable to define refractory DLBCL. The estimated 5-year cumulative incidence of refractory patients was 20% (95% confidence Interval [CI] = 18%-22%). After the determination of refractory disease, overall response rate and complete remission rate were 30% (95% CI = 22%-38%) and 9% (95% CI = 4%-15%), respectively. Patients with either no response to immunochemotherapy or relapse within 12 months after stem-cell transplantation had inferior survival with a median OS of 5.9 months (95% CI = 5.5-7.1 months) and 2-year OS rate of 16% (95% CI = 12%-20%). International prognostic index score 4-5 (hazard ratio [HR] = 2.22; 95% CI = 1.47-3.35), central nervous system relapse (HR = 1.43; 95% CI = 1.04-1.97), and best response status (HR = 2.68; 95% CI = 1.42-5.03 for partial remission. HR = 5.97, 95% CI = 3.21-11.11 for stable disease/progressive disease) were independent unfavorable prognostic factors. CONCLUSIONS This is the first large-scale Asian cohort study focusing on outcomes of refractory DLBCL. The definition of the SCHOLAR-1 study identifies patients with homogenously inferior survival, thus is appropriate to select refractory DLBCL. Due to poor clinical outcomes in the rituximab era, patients with refractory DLBCL may be potential candidates for novel treatment modalities.

Abstract
PURPOSE CD19-specific chimeric antigen receptor (CAR) T-cell therapy is effective against refractory or relapsed (R/R) B-cell lymphoma, but the efficacy is hindered by the existence of PD-1/PD-L1 pathway. PATIENTS AND METHODS Here, we generated a novel anti-CD19 CAR-expressing PD-1/CD28 chimeric switch-receptor (CD19-PD-1/CD28-CAR). We then conducted a phase Ib study to evaluate safety and efficacy of CD19-PD-1/CD28-CAR T cells in the treatment of PD-L1+ B-cell lymphoma. RESULTS We found that CD19-PD-1/CD28-CAR T cells had superior T-cell proliferation, cytokine production, and sequentially capability of killing PD-L1+ B-cell lymphoma cells in vitro and in vivo relative to the prototype, CD19-CAR T cells. Among 17 adult patients with R/R lymphoma who received the CAR T therapy, 10 patients had objective response (58.8%), including seven patients with complete remission (41.2%). At a median follow-up 15 months, median overall survival for all patients was not reached. Remarkably, no severe neurologic toxicity or cytokine release syndrome was observed. CONCLUSIONS This first-in-human study demonstrates the tolerability, safety, and encouraging efficacy of CD19-PD-1/CD28-CART in PD-L1+ large B-cell lymphoma.

Abstract
Using renewable microalgal biomass as active feedstocks for biofuels and bioproducts is explored to substitute petroleum-based fuels and chemicals. In the last few years, the importance of microalgae biomass has been realized as a renewable feedstock due to several positive attributes associated with it. Biorefinery via anaerobic digestion (AD) of microalgal biomass is a promising and sustainable method to produce value-added chemicals, edible products and biofuels. Microalgal biomass pretreatment is a significant process to enhance methane production by AD. Findings on the AD microbial community's variety and organization can give novel in turn on digester steadiness and presentation. This review presents a vital study of the existing facts on the AD microbial community and AD production. Co-digestion of microalgal biomass with different co-substrates was used in AD to enhance biogas production, and the process was economically viable with improved biodegradability. Microcystins, which are produced by toxic cyanobacterial blooms, create a severe hazard to environmental health. Anaerobic biodegradation is an effective method to degrade the microcystins and convert into nontoxic products. However, for the cost-effective conversion of biomass to energy and other beneficial byproducts, additional highly developed research is still required for large-scale AD of microalgal biomass.

Abstract
Relapsed and refractory (R/R) mantle cell lymphoma (MCL) remains an incurable lymphoma with a poor prognosis. Recently, there are a few studies demonstrating the efficacy of anti-CD19 chimeric antigen receptor T (CAR-T) cell therapy in MCL, including ZUMA-2 study in which CD28-based CAR-T cells were used. However, long-term efficacy and safety associated with 4-1BB-based CAR-T therapy in MCL are not defined well. Here, we report three male patients with R/R classical MCL, who received CD19-directed 4-1BB CAR-T therapy and achieved complete remission, showed mild symptoms of cytokine-release syndrome (CRS) and had no neurological toxicity. During a follow-up of 24–35 months, all three patients remained in complete remission. Persistent B-cell depletion was observed in two patients. Recovery of CD19+ polyclonal B cells was detected in one patient at 6 months after CAR-T cell infusion. Recovery of serum immunoglobulin, including IgG, IgA and IgM, was not observed in two patients at the last follow-up. Only one patient developed herpes zoster, and the other two patients had no serious infection. This is the first report about the efficacy, long-term remission and safety of CD19-directed 4-1BB CAR-T therapy in R/R MCL.

Abstract
Abstract
Background
There is growing evidence that women with ischemia and no obstructive coronary artery disease (INOCA) have an increased risk of major adverse cardiovascular events (MACE). Half of these women continue to experience persistent chest pain (PChP); however longer-term outcomes are unknown.
Purpose
To investigate the relationships between PChP at 1-year with obstructive and nonobstructive coronary artery disease (CAD) and longer-term all-cause mortality, MACE and angina hospitalization in women with suspected myocardial ischemia.
Methods
We studied 673 women with chest pain undergoing coronary angiography for suspected myocardial ischemia in the National Heart, Lung, and Blood Institute Women's Ischemia Syndrome Evaluation (WISE) study. PChP was defined as self-reported continuing chest pain at 1-year, obstructive CAD as >50 stenosis in any coronary artery and non-obstructive CAD was further divided as <20% stenosis and 20–50% stenosis in any coronary artery. The Kaplan-Meier method was used to estimate cumulative incidence rates of all-cause mortality, MACE, and angina hospitalization. Proportional hazards regression estimated adjusted hazard ratios of mortality, MACE and angina hospitalization in relation to PChP at 1-year in obstructive and nonobstructive CAD.
Results
The median age was 58 years, 45% had PChP, and 39% had obstructive CAD with a median follow-up time of 9 years (range 1 to 11) for mortality and 5 years (range 0 to 9) for MACE and anginal hospitalization. There was no difference in mortality or MACE in women with PChP compared to women without PChP in any of the 3 groups (<20%, 20–50%, or >50% CAD), however differences were noted in long-term angina hospitalization (Figure 1). Notably,angina hospitalization rates in women with PChP and nonobstructive CAD were 2.2 times those of women without PChP, and comparable to those of women with obstructive CAD and no PChP (p<0.0001).
Conclusions
Among women undergoing coronary angiography for suspected myocardial ischemia, women with nonobstructive CAD and PChP have rates of angina hospitalization comparable to patients with obstructive CAD without PChP. Thus, PChP increases the hazard of long term anginal hospitalization regardless of the presence or absence of obstructive CAD. Given the economic burden of angina hospitalization, further studies are needed to determine whether aggressive treatment in women with PChP without obstructive CAD changes outcomes and impact on the health care system.

Abstract
Abstract
Background
Emerging data suggests there is an “obesity paradox” where obesity may be protective against cardiovascular morbidity and mortality in patients with cardiovascular disease. However, weight status primarily assessed through body mass index (BMI) is limited in its ability to discern contributions from fat vs. lean muscle mass. Most studies on BMI have not accounted for physical fitness, which is a known modifier of weight status and a potential mediator of effects of obesity on major adverse cardiovascular events (MACE).
Purpose
To investigate the relationship between BMI and physical fitness, measured by self-reported Duke Activity Status Index (DASI) score, with long-term MACE in women evaluated for suspected myocardial ischemia.
Methods
The National Heart, Lung, and Blood Institute Women's Ischemia Syndrome Evaluation (WISE) study is a multicenter prospective cohort study. From 1996–2000, 936 women were enrolled at the time of clinically indicated coronary angiography and assessed with a median follow up of 5.8 (range 0–9 years) for MACE. MACE was defined as a composite of death, nonfatal myocardial infarction, stroke, or congestive heart failure. Proportional hazards regression was used to estimate adjusted hazard ratios of MACE in relation to metabolic status and physical fitness. DASI scores ≥25, equivalent to ≥7 metabolic equivalents [METs]) was used as cut point to define high physical fitness, in our prior studies DASI >25 approximates completion of the second stage of a Bruce treadmill protocol.
Results
Among the 899 women with complete data, 69.5% had low physical fitness (DASI scores <25), 34.9% overweight (BMl ≥25 to 30), 40.5% obese (BMI ≥30). In fit women, obesity was associated with lower hazard ratio for MACE (HR 0.64, p=0.01); while low fitness in normal weight women was associated with 60% excess risk of MACE (HR 1.61, p=0.01) (Figure 1).
Conclusions
Among women undergoing coronary angiography for suspected myocardial ischemia, obesity was inversely related with long-term MACE in physically fit women. Our findings suggest that physical fitness may play a role in the obesity paradox. These results support the inclusion of fitness in understanding the relations between body weight and long-term MACE. The DASI is a simple, self reported tool that can identify higher-risk symptomatic women and should be considered in future investigations and routine examination of normal, overweight and obese women.

Abstract
Purpose Diffuse large B cell lymphoma (DLBCL) is an aggressive B-cell malignancy with clinical and molecular heterogeneity whose genetics may have clinical implications for patient stratification and treatment. The circulating tumor DNA (ctDNA) is a novel noninvasive, real-time, and tumor-specific biomarker harboring tumor-derived genetic alterations that are identical to those of tumor cells, thus showing great promise in individualized medicine, including precise diagnosis, prediction of prognosis, response monitoring, and relapse detection for DLBCL. Patients and Methods In this study, we applied NGS analysis to tumor biopsies and ctDNA samples from 16 DLBCL subjects. Then, we compared the genomic alterations from 41 newly diagnosed patients and 56 relapsed/refractory (R/R) patients. Results Our results show that ctDNA can function as a liquid biopsy for tracking recurrently mutated genes in DLBCL (sensitivity: 87.50%). The mutational profiles of newly diagnosed and R/R DLBCL groups largely overlapped, but the frequencies of some gene mutations differ between the two cohorts. The distribution of mutations also revealed different frequencies in the two cohorts due to different signaling pathways. Genes from apoptosis pathway, immune response and BCR pathway suffered more mutations in R/R patients. Conclusion Overall, this study establishes ctDNA as an easily accessible source of tumor DNA for DLBCL genotyping and provides a deeper understanding of the somatic alteration spectrum for both newly diagnosed and R/R DLBCL patients.

Abstract
Clostridium tyrobutyricum shows probiotic properties and can affect the composition of gut microbiota and regulate the intestinal immune system. Compared with other probiotics, this spore-producing bacterium shows unparalleled advantages in commercial production. In addition to being resistant to extreme living environments for extended periods, its endophytic spores are implicated in inhibiting cancer cell growth. We speculated that C. tyrobutyricum spores can also promote gut health, which mean it can maintain intestinal homeostasis. To date, the beneficial effects of C. tyrobutyricum spores on gut health have not been reported. In this study, a Spo0A-overexpressing C. tyrobutyricum strain was developed to increase spore production, and its probiotic effects on the gut were assessed. Compared with the wild-type, the engineered strain showed significantly increased sporulation rates. Mice administered with the engineered strain exhibited enhanced intestinal villi and the villus height/crypt depth ratio, weight gain and improved Firmicutes/Bacteroidetes ratio to facilitate intestinal homeostasis. This study demonstrated for the first time that enhanced spore production in C. tyrobutyricum can improve intestinal homeostasis, which is advantageous for its commercial application in food and pharmaceutical industry.
