Abstract
PURPOSE Although small for gestational age (SGA) does not cause adverse perinatal outcomes, the placental pathology for fetal growth restricted (FGR) and SGA fetuses is still unknown. The aim of this study is to evaluate the differences between placentas of early onset FGR, late onset FGR, SGA, and appropriate for gestational age (AGA) pregnancies in the manner of microvasculature and expression of anti-angiogenic PEDF factor and CD68. METHODS The study included four groups (early onset FGR, late onset FGR, SGA and AGA). Placental samples were obtained just after labor in all of the groups. Degenerative criteria were investigated with Hematoxylin-eosin staining. Immunohistochemical evaluation with H score and m RNA levels of Cluster of differentiation 68 (CD68) and pigment epithelium derived factor (PEDF) were performed for each group. RESULTS The highest levels of degeneration were detected in the early onset FGR group. In means of degeneration SGA placentas were found to be worse than the AGA placentas. The intensity of PEDF and CD68 were significant in early FGR, the late FGR and SGA groups compared to the AGA group (p < 0.001). The mRNA level results of the PEDF and CD68 were also parallel to the immunostaining results. CONCLUSION Although SGA fetuses are considered constitutionally small, the SGA placentas also demonstrated signs of degeneration similar to the FGR placentas. These degenerative signs were not seen among the AGA placentas.

Abstract
OBJECTIVES Recurrent high-grade glioma, a malignant tumor of the brain or spinal cord associated with poor prognosis with a median survival of <6 months. Recurrent high-grade glioma does not have standard treatment even if some strategies have some effect in recurrent gliomas. Apatinib, as a tyrosine kinase inhibitor shown to be effective in treating the lung and gastric cancer. The present study investigated the efficacy and safety of apatinib in combination with dose-dense regimens of temozolomide for treating recurrent glioma. PATIENTS AND METHODS Eighteen patients with recurrent high-grade glioma were enrolled and treated with apatinib (500 mg/day) and TMZ (50 mg/m2/day). Patients who achieved partial response or stable disease continued treatment. Administration of drug was terminated for patients with progressive disease, who could not tolerate toxicity, and who required discontinuation due to other medical conditions. RESULTS From the 18 cases, only 17 were included in the evaluation of the curative effect of the drug and in that four showed partial responses, ten had stable disease, remaining three exhibited progressive disease. The disease control rate was 82.3% (14/17). Progression-free and overall survival was found to be 4 months and 9.1 months, respectively. Three patients became transiently capable of self-care (Karnofsky performance status >70). Cognition and quality of life improved after treatment and from the safety perspective, three most common adverse reactions included epilepsy (24.1%), hypertension (20.7%), and fatigue (17.2%). CONCLUSION Apatinib and TMZ may represent an alternative treatment option for patients with recurrent high-gradeglioma, especially those with a low Karnofsky performance status. However, studies using a larger sample size are required to confirm these findings.
