Abstract Background Neuroblastoma (NB) is the most common extracranial solid tumor in children with high heterogeneity and concealed onset. The mechanism for its occurrence and development has not been revealed. The purpose of this study was to summarize the clinical characteristics of children with NB and abnormal chromosome 10. To investigate the relationship between the number and structure of chromosome 10 abnormality and NB prognosis.MethodsWe used chromosome G-banding in the first diagnosis to evaluate the genetics of chromosomes in patients with NB, and follow up their clinical characteristics and prognosis. All participants were diagnosed with NB in Hematology Oncology Center, Beijing Children’s Hospital from May 2015 to December 2018, and were followed up for at least one year. ResultsOf all 150 patients with bone marrow metastases, 42 were clearly diagnosed with chromosomal abnormalities. There were 13 patients with chromosome 10 abnormalities definitely, and the loss of chromosome 10 was the most common decrease in the number of chromosomes. These 13 patient had higher LDH, lower OS and EFS than that of children in abnormal group without chromosome 10 abnormality. Eight patients both had MYCN amplification and 1p36 deletion. Two of them had optic nerve damage and no vision, and 1 had left supraorbital metastases five months after treatment. Among the 16 children with suspected chromosome 10 abnormalities, 3 also had orbital metastases. ConclusionsThe above results showed that chromosome 10 might be a new prognostic marker. MYCN amplification and 1p36 deletion may be related with chromosome 10 abnormalities in NB. And NB patients with abnormal chromosome 10 were prone to have orbital metastases.

Abstract Background Neuroblastoma (NB) is the most common extracranial solid tumor in children. It is known for high heterogeneity and concealed onset. In recent years, the mechanism of its occurrence and development has been gradually revealed. The purpose of this study is to summarize the clinical characteristics of children with NB and abnormal chromosome 10, and to investigate the relationship between the number and structure of chromosome 10 abnormalities and NB prognosis. Methods Chromosome G-banding was used at the time of diagnosis to evaluate the genetics of chromosomes in patients with NB and track their clinical characteristics and prognosis. All participants were diagnosed with NB in the Medical Oncology Department of the Beijing Children’s Hospital from May 2015 to December 2018 and were followed up with for at least 1 year. Results Of all 150 patients with bone marrow metastases, 42 were clearly diagnosed with chromosomal abnormalities. Thirteen patients showed abnormalities in chromosome 10, and chromosome 10 was the most commonly missing chromosome. These 13 patients had higher LDH and lower OS and EFS than children with chromosomal abnormalities who did not have an abnormality in chromosome 10. Eight patients had both MYCN amplification and 1p36 deletion. Two patients had optic nerve damage and no vision, and one patient had left supraorbital metastases 5 months after treatment. Conclusions The results indicated that chromosome 10 might be a new prognostic marker for NB. MYCN amplification and 1p36 deletion may be related to chromosome 10 abnormalities in NB. Additionally, NB patients with abnormal chromosome 10 were prone to orbital metastases.

Abstract Background Paired-like homeobox 2B (PHOX2B) is specifically expressed in the nervous system including neuroblastoma cells, but little is known about the clinical significance of the expression of PHOX2B in bone marrow (BM) and peripheral blood (PB) samples of newly diagnosed neuroblastoma patients. Methods The expression of PHOX2B in 276 paired BM and PB samples of neuroblastoma patients at diagnosis was tested by quantitative reverse transcriptase polymerase chain reaction (RT-PCR). Then the relationship between PHOX2B level and clinical characteristics including metastasis and prognosis was explored by receiver operating characteristic (ROC) analysis and Kaplan-Meier method. Results We identified the combined expression of PHOX2B in both BM and PB provided a high diagnostic accuracy for metastasis of neuroblastoma patients (AUC = 0.920) with the sensitivity and specificity of 86.7% and 92.9%, respectively. At last, 246 patients were enrolled for prognostic analysis. The median follow-up time was 22 months. Positive expressions of PHOX2B in BM and PB at diagnosis were associated with worse EFS and OS in neuroblastoma patients (P < 0.05). What’s worse, 19.7% (31/157) and 6.4% (10/157) patients with positive expression of PHOX2B in BM and PB samples in low/intermediate-risk group also had shorter EFS and poor OS (P < 0.05). CONCLUSIONS The expressions of PHOX2B in BM and PB were high in patients with unfavorable clinical characteristics. PHOX2B could be an appropriate biomarker for predicting metastasis and prognosis in patients with neuroblastoma.

Vascular injury mobilizes bone marrow–derived proangiogenic cells into the circulation, where these cells can facilitate vascular repair and new vessel formation. We sought to determine the relationship between a new biomarker of circulating bone marrow–derived proangiogenic cell activity, the presence of atherosclerotic cardiovascular disease (CVD) and its risk factors, and clinical outcomes. Circulating proangiogenic cell activity was estimated using a reproducible angiogenic colony-forming unit (CFU-A) assay in 532 clinically stable subjects aged 20 to 90 years and ranging in the CVD risk spectrum from those who are healthy without risk factors to those with active CVD. CFU-A counts increased with the burden of CVD risk factors ( p < 0.001). CFU-A counts were higher in subjects with symptomatic CVD than in those without ( p < 0.001). During follow-up of 232 subjects with CVD, CFU-A counts were higher in those with death, myocardial infarction, or stroke than in those without (110 [70–173] vs 84 [51–136], p = 0.01). Therefore, we conclude that circulating proangiogenic cell activity, as estimated by CFU-A counts, increases with CVD risk factor burden and in the presence of established CVD. Furthermore, higher circulating proangiogenic cell activity is associated with worse clinical outcome in those with CVD.

Objectives: The purpose of the current study is to review the results of meniscus repairs with and without bone marrow aspiration concentrate (BMAC). It is hypothesized that with BMAC, meniscus repair outcomes will be improved when compared to without BMAC at 1 year after surgery. Methods: This is a prospective case control study performed from August 2014 until August 2017. Patients were included if they had a meniscus repair performed with no history of prior meniscus surgery to the operative knee. Patients were excluded if there was a full thickness cartilage tear or International Cartilage Repair Society (ICRS) Grade IV cartilage tear not treated in a single staged surgery. Patients were also excluded if they did not reach the one year follow-up, had a multi-ligamentous knee injury requiring multiple staged procedures. From August 2014 until November 2015, patients had meniscus repair without BMA. Menisci were all repaired arthroscopically using inside-out, outside-in and all-inside techniques. After November 2015, all meniscus repairs were augmented with BMAC. In the BMAC group, all bone marrow was obtained from the ipsilateral femur during the time of surgery. The Biocue BMAC system (Zimmer Biomet, Warsaw Indiana) was used for bone marrow aspiration and BMAC was injected directly into the tear site after repair. Numerical data such as VAS, lysholm and IKDC was analyzed using a 2 sample T-test. Categorical data such as sex, tear location, type of tear and zone of tear were analyzed using a chi-square. Results: A total of 150 patients were initially included in the study. The average age in the control group was 26.3 versus 29.4 in the BMAC group (P=0.27). Thirty seven percent of the control group had an ACL reconstruction versus 40% in the BMAC group (P= .77). The control group improved from an average pain level of 6.1 to 1.2 and the BMAC group improved from an average pain level of 5.9 to 0.7 at the 1 year end point. Both the control group and BMAC group improved with respect to pain with no difference at the 1 year end point (P=.19). There was, however a significantly larger reduction in pain at the 6 week and 3 month time point with BMAC compared to the control group (P=.02 and P=.02 respectively). At the 1-year follow-up, the mean lysholm score improved from 43 to 92 in the control group and 43 to 90 in the BMAC group. The mean IKDC score improved from 37 to 87 in the control group and 36 to 83 in the BMAC group at the one year follow-up. Conclusion: Meniscus repair outcomes were improved at 6 weeks and 3 months post-operatively, when BMAC is used to augment meniscus repair compared to repair without BMAC. Both groups, control group and BMAC meniscus repair group had improved outcomes at 1 year post-operatively with respect to VAS, lysholm and IKDC, with no difference in complication rate.

SYNOPSISKey relatives of 33 first or early admission psychotic patients (mainly schizophrenics) were interviewed to determine household levels of expressed emotion (EE). The patients were followed up for 12 months from index admission, during which time 13 (39%) experienced psychotic relapse. There was no association between relapse rate and household EE, but correlations between individual components of EE and pre-morbid measures suggest that level of criticism may be related to less acute onset of index episode, greater elapsed time since first signs of illness, and poor adjustment in the realm of work/study. The results are discussed in the context of continuing uncertainties about the precise nature of the relationship between EE and relapse.

Objective: Persistent infection with human papillomavirus is the prerequisite for the development of cervical precancerous and cancerous lesions. The aim of this study was to determine the time-to-viral clearance in a population of human papillomavirus–infected Cameroonian women and to examine the possible predictors of viral persistence. Methods: We conducted a prospective cohort study based on a population of human papillomavirus–positive women having previously been recruited in a self-human papillomavirus-based cervical cancer screening campaign, who were invited for a control visit at 6 and 12 months. We determined human papillomavirus clearance using self-sampling (Self-HPV) and physician-sampling (Dr-HPV), which were analyzed with a point-of-care assay (GeneXpert® IV; Cepheid, Sunnyvale, CA, USA). Logistic regression was performed to assess the relationship between sociodemographic and clinical characteristics with HPV clearance according to the two sampling techniques. Results: A total of 187 participants were included in the study. At the 12 months follow-up, 79.5% (n = 104) and 65.3% (n = 86) had cleared their human papillomavirus infection according to Dr-HPV and self-HPV, respectively (p = 0.001). Only parity (>5 children) was statistically associated with viral persistence (p = 0.033). According to Dr-HPV, clearance of women treated with thermoablation at 12 months was of 84.1% versus 70.2% for non-treated women (p = 0.075). Conclusion: The human papillomavirus clearing rates found in our study are close to those found in other studies worldwide. Parity was significantly associated with human papillomavirus persistence. Larger, prospective studies are needed to confirm our results.
