007), and modified operation (P = .011) were highly correlated with the incidence of intracranial infection. The findings of this retrospective study show that age, diabetes, skin infection, bed-ridden, and modified operation of hydrocephalus significantly and independently correlated with the incidence of infection. Prospective studies are needed to assess the relationship between the incidence of infection and risk factors in patients with hydrocephalus after VPS. © 2020 Medicalhelplines.com Inc and John Wiley & Sons Ltd.INTRODUCTION Although gingival fenestrations occur with relative infrequency, their actual incidence is thought to be much higher. Furthermore, if left untreated, these mucogingival defects can lead to unfavorable sequelae which can compromise the esthetics and stability of the teeth affected. Most gingival fenestrations require surgical treatment for closure. Previously reported modalities of treatment include connective tissue grafting, acellular dermal matrix allograft, and pedicle flap approaches. This case demonstrates the first documented use of a dehydrated amnion-chorion membrane (dHACM) to treat gingival fenestration. CASE PRESENTATION A surgical approach involving a double pedicle flap and dHACM with 15 months follow-up is described. Following gentle cleansing of the defect and careful split-thickness elevation of a double-pedicle flap, the area of exposure fenestration was covered with dHACM. The overlying flap was then closed carefully to completely cover the dHACM. The case presented shows a successful clinical outcome as characterized by successful closure of the fenestration defect with nice tissue maturation. CONCLUSION The technique described in this case report demonstrates that gingival fenestrations can be successfully treated with a periodontal plastic surgical approach using dHACM with minimal patient discomfort.

OBJECTIVE To investigate if ABO, VWF levels and age have an influence on the variability of FVIII levels and consequently on the assessment of severity in non-severe HA. Patients/Methods Eighty-nine patients with non-severe HA and 82 healthy controls were included. Data on ABO was collected and FVIII clotting activity (FVIIIC) with one-stage clotting assay (FVIIIC OSA) and chromogenic substrate assay (FVIIIC CSA), FVIII antigen (FVIIIAg) and VWF antigen (VWFAg) and activity (VWFAct) were determined. RESULTS In HA FVIIIC OSA and CSA and FVIIIAg were not different between non-O (n=42, median 15.5, interquartile range 10.4-24.0; 10.0, 6.8-26.0 and 15.2, 10.7-24.9) and O (n=47, 14.1, 9.0-23.0; 10.0, 5.0-23.0 and 15.2, 9.3-35.5), whereas in healthy controls, non-O individuals had significantly higher FVIII levels. FVIII C showed no relevant correlation with VWF levels in HA, but we observed strong correlations in healthy controls. Age had only a minor influence in HA, but had a considerable impact on FVIIIC in healthy controls. In multivariable regression analysis ABO, VWFAg and age were not associated with FVIIIC in HA, whereas this model explained 61.3% of the FVIIIC variance in healthy controls. CONCLUSIONS We conclude that in non-severe HA ABO and VWF levels do not substantially influence the variability of FVIII levels and age has only minor effects on it, which is important information for the diagnostic procedures.

Elevated D-Dimer is associated with an increased risk of cancer-associated VTE. Whether changes in D-Dimer over time harbor additional prognostic information that may be exploited clinically for dynamic prediction of VTE is unclear. OBJECTIVES To explore the potential role of longitudinal D-Dimer trajectories for personalized prediction of cancer-associated VTE. PATIENTS/METHODS 167 patients with active malignancy were prospectively enrolled (gastrointestinal n=59 (35%), lung n=56 (34%), brain n=50 (30%), others n=2 (1%); metastatic disease n=74 (44%)). D-Dimer (median=0.8µg/mL [25th -75th percentile 0.4-2.0]) was measured at baseline and during 602 monthly follow-up visits. Joint models of longitudinal and time-to-event data were implemented to quantify the association between D-Dimer trajectories and prospective risk of VTE. RESULTS VTE occurred in 20 patients (250-day VTE risk=12.1%, 95%CI 7.8-18.5). D-Dimer increased by 34%/month (0.47µg/mL/month, 95%CI 0.22-0.72, p less then 0.0001) in patients who developed VTE, but remained constant in patients who did not develop VTE (change/month=-0.06µg/mL/month, 95%CI -0.15-0.02, p=0.121). In joint modeling, a doubling of the D-Dimer trajectory was associated with a 2.8-fold increase in the risk of VTE (Hazard ratio=2.78, 95%CI 1.69-4.58, p less then 0.0001). This finding was independent of established VTE risk factors. Highly personalized, dynamic predictions of VTE conditional on individual patients' D-Dimer trajectories could be obtained. CONCLUSIONS D-Dimer increases before the onset of cancer-associated VTE, but remains constant over time in patients without VTE. This study represents proof-of-concept that longitudinal trajectories of D-Dimer may advance the personalized assessment of VTE risk in the oncologic setting. This article is protected by copyright.

These alterations lead to local microenvironmental changes, which mainly manifest as a lack of oxygen and acidosis, further affecting the efficacy of chemotherapy drugs. Antiangiogenic drugs can normalize the abnormalities caused by tumor angiogenesis, thereby transferring oxygen and drugs to tumor cells more efficiently through normalized blood vessels and enhancing the efficacy of chemotherapy drugs. Apatinib is a specific VEGFR-2 inhibitor that blocks the transmission of the VEGF/VEGFR-2 signaling pathway. In this study, we constructed a nude mouse xenograft model of lung cancer and administered apatinib at different doses and times to detect the normalization of reactive blood vessels through VEGF, α-SMA, college-IV, HIF-1α, and MMP. The ultrastructure of tumor blood vessels was observed by electron microscopy, and the dose and timing of apatinib-induced normalization of lung cancer in nude mice were confirmed.
