INTRODUCTION:The US population has witnessed an epidemic expansion of obesity in the past several decades; nearly 50% of the population is projected to be obese by 2030 and 25% morbidly obese. This study examined trends, characteristics and outcomes of morbidly obese women who underwent benign hysterectomy. MATERIAL AND METHODS:This is a population-based retrospective observational study querying the National Inpatient Sample from January 2012 to September 2015. The study population included 509 395 women who underwent hysterectomy for benign gynecological disease: 430 865 (84.6%) non-obese women, 50 435 (9.9%) women with class I-II obesity and 28 095 (5.5%) women with class III obesity. Main outcome measures were (i) cohort-level trends of obesity and perioperative complications assessed by piecewise linear regression with log transformation and (ii) patient-level perioperative complication risk by body habitus assessed with a generalized estimating equation after using a multiple-group generalized boosted model. RESULTS:The rate of class III obesity increased by 40.4%, higher than the rate of class I-II obesity (22.2%) (both, P < .001). In parallel, cohort-level rates of perioperative complication and prolonged hospitalization for ≥7 days increased by 19.4% and 54%, respectively (P < .001). In a weighted model, class I-II obesity (16.4% vs 14.6%, odds ratio 1.15, 95% confidence interval 1.08-1.21) and class III obesity (19.2% vs 14.6%, odds ratio 1.39, 95% confidence interval 1.28-1.51) had a significantly increased risk of perioperative complications compared with non-obesity. Larger body habitus was associated with higher total charge (median, $35 180, $36 094 and $39 382; all values cited in US dollars) and prolonged admission rate for ≥7 days (2.9%, 3.1% and 3.9%) (both, P < .001). CONCLUSIONS:The rate of obesity, particularly morbid obesity, has significantly increased among women undergoing benign hysterectomy in the USA. Morbidly obese women had adverse perioperative outcomes, and the increasing number of morbidly obese women resulted in both an increased perioperative morbidity and total charges as a cohort. National and society-based approaches are necessary to reduce the obesity rate and hysterectomy morbidity.


引言: 在过去的几十年里,美国人口见证了肥胖的流行扩张; 预计到2030年,近50% 的人口将是肥胖的,25% 是病态肥胖。本研究调查了接受良性子宫切除术的病态肥胖女性的趋势、特征和结局。 材料和方法: 这是一项基于人群的回顾性观察研究,查询了2012年1月至2015年9月的全国住院患者样本。研究人群包括509 395名因良性妇科疾病接受子宫切除术的女性: 430 865名 (84.6%) 非肥胖女性,50 435名 (9.9%) I-II级肥胖女性和28 095名 (5.5%) III级肥胖女性。主要结果指标为 (i) 通过分段线性回归和对数转换评估的肥胖和围手术期并发症的队列水平趋势,以及 (ii) 使用多组广义增强模型后,通过广义估计方程评估的身体习惯的患者水平围手术期并发症风险。 结果: ⅲ 类肥胖率增加40.4%,高于 ⅰ-ⅱ 类肥胖率 (22.2%) (均P <.001)。同时,队列水平的围手术期并发症和延长住院时间 ≥ 7天的发生率分别增加了19.4% 和54% (P <.001)。在加权模型中,与非肥胖相比,i-ii类肥胖 (16.4% vs 14.6%,比值比1.15,95% 置信区间1.08-1.21) 和III类肥胖 (19.2% vs 14.6%,比值比1.39,95% 置信区间1.28-1.51) 显著增加了围手术期并发症的风险。较大的体型与较高的总费用 (中位数,$35 180,$36 094和 $39 382; 所有数值以美元引用) 和 ≥ 7天的延长住院率 (2.9%,3.1% 和3.9%) 相关 (两者,P <.001)。 结论: 在美国接受良性子宫切除术的妇女中,肥胖率,尤其是病态肥胖率显著增加。病态肥胖女性的围手术期结局不良,并且病态肥胖女性数量的增加导致围手术期发病率和总费用的增加。国家和社会为基础的方法是必要的,以减少肥胖率和子宫切除术的发病率。

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.
