Abstract

INTRODUCTION:Placental abruption is a serious complication in pregnancy. Its incidence varies across countries, but the information of how placental abruption varies in immigrant populations is limited. The aims of this study were to estimate the incidence of placental abruption in immigrant women compared with non-immigrants by maternal country and region of birth, reason for immigration, and length of residence. MATERIAL AND METHODS:We conducted a nationwide population-based study using data from the Medical Birth Registry of Norway and Statistics Norway (1990-2016). The study sample included 1 558 174 pregnancies, in which immigrant women accounted for 245 887 pregnancies and 1 312 287 pregnancies were to non-immigrants. Crude and adjusted odds ratios with 95% CI for placental abruption in immigrant women compared with non-immigrants were estimated by logistic regression with robust standard error estimations (accounting for within-mother clustering). Adjustment variables included year of birth, maternal age, parity, multiple pregnancies, chronic hypertension, and level of education. RESULTS:The incidence of placental abruption decreased during the study period for both immigrants (from 0.68% to 0.44%) and non-immigrants (from 0.80% to 0.34%). Immigrant women from sub-Saharan Africa had an adjusted odds ratio of 1.35 (95% CI 1.15-1.58) compared with non-immigrants for placental abruption, whereas immigrant women from Ethiopia had an adjusted odds ratio of 2.39 (95% CI 1.67-3.41). We found a small variation in placental abruption incidence by other countries or regions of birth, length of residence, and reason for immigration. CONCLUSIONS:Immigrant women from sub-Saharan Africa, especially Ethiopia, have increased odds for placental abruption when giving birth in Norway. Reason for immigration and length of residence had little impact on the incidence of placental abruption.

摘要

前言: 胎盘早剥是妊娠期严重的并发症。其发病率因国家而异,但有关胎盘早剥在移民人群中如何变化的信息有限。本研究的目的是评估移民妇女胎盘早剥的发生率,与非移民相比,孕产妇国家和出生地区,移民原因和居住时间。 材料和方法: 我们使用挪威医学出生登记处和挪威统计局 (1990-2016) 的数据进行了一项全国性的基于人群的研究。研究样本包括1 558 174例怀孕,其中移民妇女占245 887例怀孕,1 312 287例怀孕是非移民。移民女性与非移民女性胎盘早剥的粗比值比和校正比值比为95% CI,通过逻辑回归和稳健的标准误差估计 (考虑母亲内聚类) 进行估计。调整变量包括出生年份、产妇年龄、产次、多胎妊娠、慢性高血压和教育程度。 结果: 在研究期间,移民 (从0.68% 到0.44%) 和非移民 (从0.80% 到0.34%) 胎盘早剥的发生率都有所下降。与非移民相比,来自撒哈拉以南非洲的移民妇女胎盘早剥的校正比值比为1.35 (95% CI 1.15-1.58),而来自埃塞俄比亚的移民妇女的校正比值比为2.39 (95% CI 1.67-3.41)。我们发现其他国家或地区出生、居住时间和移民原因的胎盘早剥发病率有很小的差异。 结论: 来自撒哈拉以南非洲,尤其是埃塞俄比亚的移民妇女在挪威分娩时胎盘早剥的几率增加。移民原因和居住时间对胎盘早剥的发生率影响不大。

METHODS::The ATP binding-cassette superfamily corresponds the mostly transmembrane transporters family found in humans. These proteins actively transport endogenous and exogenous substrates through biological membranes in body tissues, so they have an important role in the regulation of many physiological functions necessary for human homeostasis, as well as in response regulation to several pharmacological substrates. The development of multidrug resistance has become one of the main troubles in conventional chemotherapy in different illnesses including cancer, being the increased efflux of antineoplastic drugs the main reason for this multidrug resistance, with a key role of the ABC superfamily. Likely, the interindividual variability in the pharmacological response among patients is well known, and may be due to intrinsically factors of the disease, genetic and environmental ones. Thus, the understanding of this variability, especially the genetic variability associated with the efficacy and toxicity of drugs, can provide a safer and more effective pharmacological treatment, so ABC genes are considered as important regulators due to their relationship with the reduction in pharmacological response. In this review, updated information about transporters belonging to this superfamily was collected, the possible role of these transporters in cancer, the role of genetic variability in their genes, as well as some therapeutic tools that have been tried to raise against main transporters associated with chemoresistance in cancer.

METHODS:BACKGROUND:Cholinergic neurotransmission regulates neuroinflammation in Parkinson disease (PD). RESEARCH DESIGN AND METHODS:The authors conducted a delayed-start study of donepezil for cognitive decline in non-demented PD patients. The study consisted of a 96-week randomized placebo-controlled double-blind phase 1, followed by a 24-week donepezil extension phase 2. The primary outcome measure was a change in the Mini-Mental State Examination (MMSE) at week 120. RESULTS:A total of 98 patients were randomly allocated to the early-start (donepezil-to-donepezil) and delayed-start (placebo-to-donepezil) groups. Mean (SD) of the baseline MMSE was 27.6 (2.0) and 28.0 (2.1), respectively. MMSE change at week 120 was better in the early-start group than in the delayed-start group, but the difference was not significant. The MMSE declined in apolipoprotein ε4 carriers, but not in non-carriers, and the factor interaction (intervention × ε4 genotype) was highly significant (P < 0.001). Analyzed with the interaction, the difference was significant (group difference 1.95 [0.33 to 3.57], P = 0.018). The MMSE decline slope in phase 1 was significantly better in the early-start group than in the delayed-start group (P = 0.048). CONCLUSIONS:Cognitive function deteriorated in ε4 carriers, but not in non-carriers, and early-start donepezil may postpone cognitive decline in the former.

METHODS::Since the discovery of dental pulp stem cells, a lot of teams have expressed an interest in dental pulp regeneration. Many approaches, experimental models and biological explorations have been developed, each including the use of stem cells and scaffolds with the final goal being clinical application in humans. In this review, the authors' objective was to compare the experimental models and strategies used for the development of biomaterials for tissue engineering of dental pulp with stem cells. Electronic queries were conducted on PubMed using the following terms: pulp regeneration, scaffold, stem cells, tissue engineering and biomaterial. The extracted data included the following information: the strategy envisaged, the type of stem cells, the experimental models, the exploration or analysis methods, the cytotoxicity or viability or proliferation cellular tests, the tests of scaffold antibacterial properties and take into account the vascularization of the regenerated dental pulp. From the 71 selected articles, 59% focused on the "cell-transplantation" strategy, 82% used in vitro experimentation, 58% in vivo animal models and only one described an in vivo in situ human clinical study. 87% used dental pulp stem cells. A majority of the studies reported histology (75%) and immunohistochemistry explorations (66%). 73% mentioned the use of cytotoxicity, proliferation or viability tests. 48% took vascularization into account but only 6% studied the antibacterial properties of the scaffolds. This article gives an overview of the methods used to regenerate dental pulp from stem cells and should help researchers create the best development strategies for research in this field.
