INTRODUCTION:Risk factors for pelvic floor disorders are often related to pregnancy and delivery. Consistent evidence is needed to develop prevention strategies targeting risk factors. The objective of this study is to identify which pregnancy- and/or obstetric-related risk factors can predict urinary incontinence, fecal incontinence, or pelvic organ prolapse later in life by means of a systematic review and meta-analysis. MATERIAL AND METHODS:Systematic review Prospero number: CRD42019131758. Literature searches of PubMed, EMBASE, CINAHL, and Cochrane Library were conducted according to PRISMA guidelines (April 2020). Prospective cohort studies describing more than two pregnancy- and/or obstetric-related risk factors on urinary incontinence, fecal incontinence (including flatal incontinence), or pelvic organ prolapse were eligible. Risk of bias was assessed (using Quality In Prognosis Studies [QUIPS]). Studies with high risk of bias were excluded. Data were extracted and checked for accuracy with the CHARMS checklist. Sub-groups were used to distinguish between a short- and long-term follow-up period: <18 months (shortterm) and >18 months (long-term) postpartum. Odds ratios were calculated from reported prevalence rates. Log odds ratios were calculated using SPSS v.24. Variables were pooled using RevMan5. RESULTS:Data were extracted from nineteen studies for urinary incontinence, nine for fecal incontinence, and two for pelvic organ prolapse. Multivariate analysis was not possible because of the heterogeneity of the population and outcome measures. Pooled univariate risk factors for urinary incontinence were: urinary incontinence during pregnancy, instrumental vaginal delivery, episiotomy, tears, and constipation. Pooled univariate risk factors for fecal incontinence were: fecal incontinence during pregnancy, maternal age over 35 years, prenatal body mass index over 30 kg/m2 , instrumental vaginal delivery, a spontaneous vaginal delivery, oxytocin augmentation, and when the weight of the newborn was more than 4000 g. Both studies for pelvic organ prolapse had a short-term follow-up period and cesarean section was the only risk factor that could be pooled. CONCLUSIONS:Pregnancy- and obstetric-related risk factors predicting pelvic floor disorders postpartum are multifactorial and differ between pelvic floor disorders. The strongest risk factor for incontinence later in life was incontinence during pregnancy. Better quality research with long-term follow up is needed on this topic.


引言: 盆底疾病的危险因素往往与妊娠和分娩有关。需要一致的证据来制定针对风险因素的预防策略。本研究的目的是通过系统回顾和荟萃分析,确定哪些妊娠和/或产科相关的风险因素可以预测尿失禁,大便失禁或盆腔器官脱垂。 材料和方法: 系统评价Prospero编号: crd42019131758。根据PRISMA指南 (2020年4月) 对PubMed、EMBASE、CINAHL和Cochrane Library进行文献检索。描述尿失禁、大便失禁 (包括食管裂孔性尿失禁) 或盆腔器官脱垂的两个以上妊娠和/或产科相关危险因素的前瞻性队列研究是合格的。评估偏倚风险 (使用预后研究中的质量 [QUIPS])。排除偏倚风险高的研究。提取数据并使用魅力清单检查准确性。亚组用于区分短期和长期随访期: <18个月 (短期) 和> 18个月 (长期) 产后。根据报告的患病率计算比值比。使用SPSS v.24计算对数比值比。使用revman5汇总变量。 结果: 从19项关于尿失禁的研究中提取数据,9项关于大便失禁,2项关于盆腔器官脱垂。由于人群和结果测量的异质性,多变量分析是不可能的。尿失禁的单变量危险因素汇总为: 妊娠期尿失禁,器械阴道分娩,会阴切开术,流泪和便秘。大便失禁的单变量危险因素汇总为: 妊娠期大便失禁,产妇年龄超过35岁,产前体重指数超过30千克kg/m2,器械阴道分娩,阴道自然分娩,催产素增加,当新生儿体重超过4000g时。两项关于盆腔器官脱垂的研究都有短期随访期,剖宫产是唯一可以汇总的危险因素。 结论: 妊娠和产科相关的危险因素预测产后盆底疾病是多因素的,并且盆底疾病之间存在差异。在以后的生活中尿失禁的最强风险因素是怀孕期间的尿失禁。需要对这一主题进行更高质量的长期随访研究。

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.
