Abstract
Background Real-time remote-based cardiac rehabilitation (CR) programmes improve exercise capacity. However, satisfaction and performance improvements after remote-based CR remain unclear. In addition to physical function, subjective satisfaction and objective performance may be adversely affected during the coronavirus disease 2019 pandemic. Purpose This study aimed to compare the effectiveness of real-time remote-based CR versus hospital-based CR in improving physical function, subjective satisfaction, and objective performance (i.e., activity limitations and participation restrictions). Methods We conducted a quasi-randomised controlled trial and recruited 38 patients with cardiovascular disease (CVD). The patients participated in 4 weeks of hospital-based CR, followed by 12 weeks of remote or hospital-based CR based on quasi-randomised allocation. We assessed the participants at baseline and after 12 weeks of remote or hospital-based CR using the shortened version of the World Health Organization Quality of Life scale (WHOQOL-BREF) for subjective satisfaction, the World Health Organization Disability Assessment Schedule (WHODAS 2.0) for objective performance, and peak oxygen uptake (peak VO2) using the cardiopulmonary exercise test, for physical function. We evaluated individual results by measuring baseline to post-CR changes (i.e., delta [Δ]) (paired t-test) and then compared the remote and hospital-based CR programmes (unpaired t-test). Results Sixteen patients (72.2±10.4 years) completed remote-based CR and fifteen patients (77.3±4.8 years) completed hospital-based CR. Seven patients were excluded owing to other health complications (n=2) and inability to attend hospital based-CR (n=5). In the remote-based CR group, the peak VO2 (before: 12.0±2.7 mL min–1 kg–1; after: 14.9±3.9 mL min–1 kg–1; p<0.05) and the WHOQOL-BREF score (before: 77.4±12.8 points; after: 93.9±12.9 points; p<0.001) were significantly higher, whereas the WHODAS 2.0 score was significantly lower (before: 19.9±13.2 points; after: 11.3±6.8 points; p<0.05) after rehabilitation than at baseline. The post-CR physical function differed significantly between the two groups (Δpeak VO2, remote: 2.8±3.0 mL min–1 kg–1; hospital: 0.84±1.8 mL min–1 kg–1; p<0.05). The post-CR change in the WHOQOL-BREF score was not significantly different between the groups. The post-CR change in the WHODAS 2.0 score was significantly lower in the remote-based CR group than in the hospital-based CR group. (ΔWHODAS 2.0 score, remote: –8.56±14.2 points; hospital: 2.14±7.6 points; p<0.01). Conclusions Remote-based CR significantly improved physical function and objective performance in patients with CVD. Remote-based CR could be an effective treatment for stable patients who are unable to visit the hospital during the coronavirus disease 2019 pandemic. In the future, risk stratification according to severity of illness is needed. Funding Acknowledgement Type of funding sources: Private company. Main funding source(s): Sanei Medicis company.

Abstract
In previous reports, the authors showed a significant overall increase in neoplasms originating from the ovaries (2007) and increased body weights (2007, 2010) in female B6C3F1 mice chronically exposed to low dose-rate γ-rays at 20 mGy/day (total doses = 8 (2007) or 6 Gy (2010)), as well as significant increases in serum leptin, total cholesterol, adipose tissue deposits and liver lipid content (2010). The present study chronicles the progression of ovarian failure in relation to obesity and dyslipidemia in female B6C3F1 mice chronically exposed to low dose-rate of γ-rays from 9 to 43 weeks of age (total dose = 4.8 Gy). We monitored changes in body weights, estrus cycles, ovarian follicle counts, serum cholesterol and serum leptin. The number of mice with irregular estrus cycles and increased body weights (with increased fat deposits) significantly increased from 30-36 weeks of age. Depletion of oocytes in ovaries from irradiated mice at 30 weeks of age (accumulated dose = 3 Gy) was also observed. Findings suggest that obesity in female B6C3F1 mice continuously irradiated with low dose-rate of γ-rays at 20 mGy/day is a consequence of premature menopause due to radiation-induced oocyte depletion.

Abstract
The aim of this study was to elucidate the nature of decidual polyp (DP) and to compare DP outcomes treated with cervical cerclage for a shortened cervix with the outcomes of cases treated with cervical cerclage without DP. The medical records of pregnant women who were complicated with cervical polyps were retrospectively reviewed. Cervical cerclage was considered for those cases with a shortened cervical length of under 25 mm and before 25 gestational weeks. We also reviewed pregnant women who had no cervical polyps, and who underwent cervical cerclage during the same study period, and defined them as the control group. A total of 56 pregnant women with cervical polyps were identified. All of the polyps in the 14 cases that had undergone cervical cerclage migrated into the cervical canal. Of the thirty seven cases with cervical polyps that did not necessitate cervical cerclage, eight women delivered preterm and six of these cases were diagnosed as DP. In all of the women studied, polyp migration was observed in 68.6 %. Cervical cerclage was performed significantly earlier in the DP group than in the control group of 46 cases (p < 0.001; 18.4 weeks vs. 21.4 weeks, respectively). Cervical cerclage is effective in DP cases with a shortened cervical length and polypectomy should not be performed during pregnancy because of the risk of miscarriage.

Abstract
BackgroundWe have previously reported that stimulation of mouse bone marrow–derived macrophages with tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) induces differentiation of osteoclast-like cells having bone resorption ability1. Recently, we have shown that the combination of TNF-α and IL-6 can induce osteoclasts from human peripheral blood mononuclear cells (PBMCs) via RANKL-independent pathways, and that there are functional differences between TNF-α and IL-6-induced osteoclasts (T6-OCs) and RANKL-induced, conventional osteoclasts (cOCs). In particular, the number of T6-OCs differentiated from PBMCs in patients with rheumatoid arthritis (RA) positively correlated with the modified total Sharp score (mTSS)2. On the other hands, no such correlation was observed between the number of cOCs from RA and mTSS.ObjectivesObjectives of this study were to compare the differentiational potential into T6-OCs of PBMCs from RA patients with those from healthy donors, to clarify mRNA and protein expressions of T6-OCs derived from PBMCs from patients with RA, and to identify tartrate resistant acid phosphatase (TRACP) positive multinuclear cells with the same characters as T6-OCs histologically in the sub-chondral bone tissues from patients with RA and osteoarthritis (OA).MethodsPBMCs and CD14+ monocytes derived from RA patients and healthy volunteers were stimulated with TNF-α and IL-6 or RANKL. Real-time quantitative PCR and immunofluorescence staining were used to measure expression levels of osteoclast-associated mRNA and protein. Consecutive sections of the proximal tibial bone tissue from patients with RA and OA (n=6 each) were stained by TRACP, and analyzed expression levels of osteoclast-associated molecules by immunohistochemistry.ResultsThe number of T6-OCs differentiated from PBMCs in RA patients was significantly increased compared to that in healthy volunteers. Expression levels of RANK mRNA and protein were clearly up-regulated in cOCs differentiated from CD14+ monocytes and were down-regulated in T6-OCs. In contrast, expression levels of MMP-3 mRNA and protein were obviously up-regulated in T6-OCs and down-regulated in cOCs. Therefore, we believe T6-OCs and cOCs were differently identified on bone tissue as TRACP+RANK-/MMP-3+ cells and TRACP+RANK+/MMP-3- cells, respectively. The numbers of TRACP+ osteoclasts in subchondral cancellous bone were significantly increased in RA patients compared to those in OA patients. Interestingly, numerous TRACP+/RANK-/MMP-3+ osteoclasts were present in the subchondral bone from patients with RA, on the other hands, no such cells observed in OA patients.ConclusionThe PBMCs of RA patients have definitely increased differentiation capacity into T6-OCs, which have potential of degrading chondral tissue. Additionally, cells having same characteristics with T6-OCs are observed in subchondral bone of patients with RA. These results suggest that novel T6-OCs may be involved in the pathogenic mechanisms of inflammatory bone destruction in patients with RA.References[1]Yokota K, Sato K, Miyazaki T, Kitaura H, Kayama H, Miyoshi F, Araki Y, Akiyama Y, Takeda K, Mimura T.

Abstract
UNLABELLED This population-based cohort study with a 3-year follow-up revealed that the annual incidence rates of vertebral fracture (VF) and severe VF (sVF) were 5.9%/year and 1.7%/year, respectively. The presence of mild VF at the baseline was a significant risk factor for incident sVF in participants without prevalent sVF. INTRODUCTION This study aimed to estimate the incidence of morphometric vertebral fracture (VF) and severe VF (sVF) in men and women and clarify whether the presence of a mild VF (mVF) increases the risk of incident sVF. METHODS Data from the population-based cohort study, entitled the Research on Osteoarthritis/Osteoporosis Against Disability (ROAD) study, were analyzed. In total, 1190 participants aged ≥ 40 years (mean age, 65.0 ± 11.2) years completed whole-spine lateral radiography both at the third (2012-2013, baseline) and fourth surveys performed 3 years later (2015-2016, follow-up). VF was defined using Genant's semi-quantitative (SQ) method: VF as SQ ≥ 1, mVF as SQ = 1, and sVF as SQ ≥ 2. Cumulative incidence of VF and sVF was estimated. Multivariate logistic regression analyses were performed to evaluate risk factors for incident sVF. RESULTS The baseline prevalence of mVF and sVF were 16.8% and 6.0%, respectively. The annual incidence rates of VF and sVF were 5.9%/year and 1.7%/year, respectively. The annual incidence rates of sVF in participants without prevalent VF, with prevalent mVF, and with prevalent sVF were 0.6%/year, 3.8%/year, and 11.7%/year (p < 0.001), respectively. Multivariate logistic regression analyses in participants without prevalent sVF showed that the adjusted odds ratios for incident sVF were 4.12 [95% confident interval 1.85-9.16] and 4.53 [1.49-13.77] if the number of prevalent mVF at the baseline was 1 and ≥ 2, respectively. CONCLUSIONS The annual incidence rates of VF and sVF were 5.9%/year and 1.7%/year, respectively. The presence of prevalent mVF was an independent risk factor for incident sVF.

Abstract
The Hayabusa2 spacecraft investigated the C-type (carbonaceous) asteroid (162173) Ryugu. The mission performed two landing operations to collect samples of surface and subsurface material, the latter exposed by an artificial impact. We present images of the second touchdown site, finding that ejecta from the impact crater was present at the sample location. Surface pebbles at both landing sites show morphological variations ranging from rugged to smooth, similar to Ryugu's boulders, and shapes from quasi-spherical to flattened. The samples were returned to Earth on 6 December 2020. We describe the morphology of >5 grams of returned pebbles and sand. Their diverse color, shape, and structure are consistent with the observed materials of Ryugu; we conclude that they are a representative sample of the asteroid.

Among the patients with severe aortic stenosis who underwent TAVR, those with baseline serum troponin-T level ≥51.5 ng/L were excluded. The impact of increases in serum troponin-T level to an abnormally high range (≥51.5 ng/L) following TAVR on 2-year cardiovascular death or heart failure readmissions was investigated.
Results
Among 189 included patients (median 86 years old, 28% men), serum troponin-T level increased in 79 patients following TAVR. An increase in serum troponin-T was associated with a higher rate of 30-day adverse events, predominantly due to pacemaker implantation for complete atrio-ventricular block, and a higher 2-year cumulative incidence of the primary endpoint (hazard ratio 3.97, 95% confidence interval 1.51-10.4, p = 0.005) adjusted for the use of balloon-expandable valve and post-TAVR pacemaker implantation (Figure 1).
Conclusion
Post-procedural increase in serum troponin-T level was associated with adverse clinical outcomes following TAVR. Abstract Figure. Cumulative incidence of endpoint
