    目的:几十年来,性别特征(VSC)变异的患者一直得不到足够的治疗。2006年芝加哥共识声明旨在引入改进的全面护理,其中包括由多学科小组组织的从儿科到成人服务的护理过渡。然而,过渡性护理的证据很少.本文的目的是概述为患有VSC的青少年和年轻成年人提供护理的过渡。
    方法:由中央的护理团队与医疗保健专业人员和同伴支持小组进行了七个焦点小组,北方,和西欧。使用反身主题分析检查了焦点组的数据。
    结果:尽管在过去的二十年中已经实施了护理过渡,它仍然不足。各国之间存在差异,因为护理质量取决于可用资源和性别特征的变化。此外,护理的适当过渡存在重大障碍,因为缺乏时间和资金。缺乏成人护理提供者和社会心理支持通常会使拥有VSC的年轻人独自驾驭医疗保健系统。
    结论:研究结果表明,护理过渡是通过儿科内分泌科组织的。由于资源和性别特征的差异,护理质量有所不同。缺乏成人专家,尤其是社会心理支持,这是年轻人和成年人在导航医疗保健系统和改善向成年人提供医疗保健方面的最大障碍。有再次创伤的风险,因为青少年和年轻人必须经常重复他们的病史和教育成人护理提供者没有足够的培训和知识。
    OBJECTIVE: People with variations in sex characteristics (VSCs) have been receiving inadequate care for many decades. The Chicago consensus statement in 2006 aimed to introduce improved comprehensive care, which would include the transition of care from pediatric to adult services organized by multidisciplinary teams. Yet, the evidence for transitional care is scarce. The aim of this paper is to outline the delivery of transition of care for adolescents and young adults with VSCs.
    METHODS: Seven focus groups were conducted with health care professionals and peer support groups by care teams in Central, Northern, and Western Europe. The data from the focus groups were examined using reflexive thematic analysis.
    RESULTS: Even though the transition of care has been implemented in the last two decades, it remains inadequate. There are differences among countries, as the quality of care depends on available resources and variations in sex characteristics. Moreover, there are significant hurdles to adequate transition of care, as there is lack of time and funding. The lack of adult care providers and psychosocial support often leaves young adults with VSCs to navigate the health care system alone.
    CONCLUSIONS: The outcome of the study shows that the transition of care is organized through the department of pediatric endocrinology. The quality of care varies due to resources and variations in sex characteristics. A lack of adult specialists, and especially psychosocial support, represents the biggest obstacle for young adults and adults in navigating the health care system and for improvements in the provision of health care to adults. There is a risk of re-traumatization, as adolescents and young adults must often repeat their medical history and educate adult care providers who are insufficiently trained and knowledgeable.

    糖尿病可以通过在糖尿病前期改变生活方式来预防。最近在尼泊尔测试了一项名为“糖尿病预防教育计划”(DiPEP)的基于小组的生活方式干预措施。本研究旨在探索参与DiPEP的糖尿病前期患者改变生活方式的经验。这项定性研究,对20名参与者进行半结构化访谈,在DiPEP干预后4-7个月进行。通过专题分析进行数据分析。结果包括四个主题,了解糖尿病是可以预防的,生活方式的改变,需要克服的障碍,并体验导致持续变化的好处。一些参与者说,知道他们有机会预防糖尿病,他们感到宽慰。参与者主要谈论改变饮食(减少碳水化合物的摄入)和体育锻炼(开始锻炼)。提到的障碍包括缺乏动力和缺乏家庭支持来实施变革。据报道,经历减肥和降低血糖水平等好处会使他们保持所做的改变。了解糖尿病可以预防是实施变革的关键动力。在类似的环境中设计生活方式干预计划时,可以考虑本研究参与者所经历的益处和障碍。
    Diabetes can be prevented through lifestyle modification in the prediabetic phase. A group-based lifestyle intervention called \'Diabetes Prevention Education Program\' (DiPEP) was tested recently in Nepal. The present study aimed to explore experiences of making lifestyle changes among people with prediabetes participating in the DiPEP. This qualitative study, with semi-structured interviews of 20 participants, was conducted 4-7 months following DiPEP intervention. Data analysis was performed by thematic analysis. The results included four themes, understanding that diabetes could be prevented, lifestyle changes made, hurdles to overcome, and experiencing benefits leading to sustained change. Some participants said they felt relieved to know that they had a chance to prevent diabetes. The participants talked mostly about making changes in diet (reducing carbohydrate intake) and physical activity (starting exercises). Obstacles mentioned included a lack of motivation and a lack of family support to implement changes. Experiencing benefits such as weight loss and reduced blood sugar levels were reported to lead them to maintain the changes they had made. Understanding that diabetes could be prevented was a key motivator for implementing changes. The benefits and hurdles experienced by the participants of the present study can be taken into consideration while designing lifestyle intervention programs in similar settings.

    There is limited literature analyzing pediatric hurdle injuries based on sex and age. This study compares hurdle-related injury types, injured body parts, and injury mechanisms by age and sex in pediatrics. Hurdle-related injury data from the National Electronic Injury Surveillance System were used to retrospectively review the injuries of hurdlers 18 years and under. Differences in injured body parts, injury types, and mechanisms were analyzed by age (pre-high school vs. high school) and sex (male vs. female). A total of 749 cases were extracted. Fractures were more common in pre-high schoolers (34.1% vs. 21.5%, p = 0.001), while more sprains were identified in high schoolers (29.6%) than pre-high schoolers (22.8%, p = 0.036). Males suffered more fractures than females (35.1% vs. 24.3%, p = 0.001). Females sustained more joint sprains (29.1% vs. 21.0%, p = 0.012) and contusions/hematomas (12.7% vs. 7.5%, p = 0.020). Ankle injuries were more common in females (24.0%) than males (12.0%, p = 0.001), while wrist injuries were more prevalent in males (11.7% vs. 7.2%, p = 0.034). The most common injury mechanism was apparatus-related, with no differences based on age or sex. Injury types and injured body parts differed depending on age and sex in pediatric hurdle injuries seen in emergency departments. These findings may be helpful for injury prevention and medical care for pediatric hurdlers.

    Curcumin is the most important active component in turmeric extracts. Curcumin, a natural monomer from plants has received a considerable attention as a dietary supplement, exhibiting evident activity in a wide range of human pathological conditions. In general, curcumin is beneficial to human health, demonstrating pharmacological activities of anti-inflammation and antioxidation, as well as antitumor and immune regulation activities. Curcumin also presents therapeutic potential in neurodegenerative, cardiovascular and cerebrovascular diseases. In this review article, we summarize the advancements made in recent years with respect to curcumin as a biologically active agent in malignant tumors, Alzheimer\'s disease (AD), hematological diseases and viral infectious diseases. We also focus on problems associated with curcumin from basic research to clinical translation, such as its low solubility, leading to poor bioavailability, as well as the controversy surrounding the association between curcumin purity and effect. Through a review and summary of the clinical research on curcumin and case reports of adverse effects, we found that the clinical transformation of curcumin is not successful, and excessive intake of curcumin may have adverse effects on the kidneys, heart, liver, blood and immune system, which leads us to warn that curcumin has a long way to go from basic research to application transformation.

    这项研究旨在比较世界级男女短跑跨栏运动员在跨栏间隙中的关节运动学和质心参数,参加世锦赛决赛的人.这是第一项关于跨栏间隙的时间序列运动学数据的研究,并分析了运动员的技术能力,在分析类似比赛和训练中其他运动员的技术时,它可以用作模板。使用四个高速摄像机(150Hz)收集了2017年国际田联世界锦标赛16名决赛选手的视频数据。视频文件被连续手动数字化,从跨栏前的着陆到跨栏前的着陆,直到男人的第六个障碍和女人的第五个障碍后的脚趾,并在关键离散时间点使用独立t检验进行基于性别的比较,并在整个跨栏阶段使用统计参数映射。当相对于跨栏高度计算时,在整个分析序列中,女性的重心高度显著大于男性(p<0.001).在跨栏间隙起飞时,男性在起飞前还表现出更多的髋部屈曲(p=0.029),以及在飞行和着陆时间隔时(p≤0.037)的膝关节更伸展。女性完成跨栏阶段的时间明显短于男性(差异约11%,p<0.001)。最后,在跨栏阶段的前40%,女性通过保持甚至超过她们的进入速度,似乎更有效率。这些结果表明,妇女成功谈判过关的技术需求较低,因此提供了进一步的证据来支持这样的论点,即女性的跨栏高度对于她们的表现能力来说太低,应该在高级比赛中提高。
    This study aimed to compare joint kinematics and center of mass parameters throughout hurdle clearance between world-class men and women sprint hurdlers, who were competing in a World Championships final. This was the first study to present time-series kinematic data around hurdle clearance, and given the technical ability of the athletes analyzed, it can be used as a template when analyzing the technique of other athletes in similar competitions and training. Video data were collected of the 16 finalists at the 2017 IAAF World Championships using four high-speed cameras (150 Hz). Video files were continuously digitized manually from touchdown before hurdle clearance to toe-off after landing around the sixth hurdle for men and the fifth hurdle for women, and sex-based comparisons were made at key discrete time points using independent t-tests, and throughout the entire hurdle phase using statistical parametric mapping. When calculated relative to hurdle height, the women\'s center of mass height was significantly greater than the men\'s throughout the full analyzed sequence (p < 0.001). Men also displayed more hip flexion in the lead leg at take-off before hurdle clearance (p = 0.029) as well as a more extended knee joint at intervals during flight and upon landing (p ≤ 0.037). Women completed the hurdle phase in a significantly shorter time than men (~11% difference, p < 0.001). Finally, women seemed to be more efficient by maintaining and even exceeding their entry velocity for the first 40% of the hurdle phase. These results show a lower technical demand for the women to successfully negotiate hurdle clearance, thus providing further evidence to support the argument that the women\'s hurdle height is too low for their performance capabilities and should be raised in senior competition.

    Clostridium sporogenes has been widely used as a surrogate for proteolytic C. botulinum for validating thermal processes in low-acid cans. To limit the intensity of heat treatments, industrials must use other ways of control as an association of acidic and saline environment after a low heat treatment. The probability of growth of pH (7-4.4), sodium chloride concentration (0-11%) and heat treatment (80°C-10 min; 100°C-1.5 min and 5.2 min) were studied on C. sporogenes PA 3679 spores and vegetative cells. Vegetative cells or heat-treated spores were inoculated in PYGm broth at 30 °C for 48 days in anaerobic conditions. Vegetative cells growth (pH 4.6-pH 4.5; 7%-8% NaCl) range is larger than the spore one (pH 5.2-pH 5.0; 6%-7% NaCl). Spores germination and outgrowth rage is decreased if the spores are heat-treated at 100 °C for 1.5 min (pH 5.5-5.3; 4%-5% NaCl) and 5.2 min (pH 5.7-5.3; 4%-5% NaCl). The C. sporogenes PA 3679 spores germination and outgrowth is impacted by their physiological state. The synergic interaction between environmental factors (pH and NaCl) and the physiological state (vegetative cells and spores) opening new possibilities for optimizing food formulation processes to manage the risks of C. sporogenes spoilage.

    最近,消费者对新鲜的需求,营养丰富,方便食品显着增加。这种趋势迫使最低限度加工和/或预包装的水果和蔬菜产品的销售增加。新产品开发和植物性食品的多样化支持了这一增长。食品生产部门应平衡这一要求与提供具有延长保质期的安全食品的必要性,同时满足消费者对新型食品的需求。营养丰富,和负担得起的食品。使用替代“软障碍”可能会导致微生物活动或其他生理/化学降解反应导致的食物变质和变质率降低。本文的目的是对新鲜水果和蔬菜在加工和包装过程中实施的可用障碍的防腐效果进行系统的审查,专注于最近的应用,旨在提高产品质量和延长其有限的保质期。
    Recently, consumers\' demand for fresh, nutritious, and convenient food has shown a significant rise. This trend has forced increased sales of minimally processed and/or pre-packed fruit- and vegetable-based products. New product development and the diversification of plant-based foods have supported this growth. The food production sector should balance this requirement with the necessity to provide safe food with extended shelf life while meeting consumer demands for novel, nutritious, and affordable food products. The use of alternative \"soft hurdles\" may result in a decrease in the rate of food deterioration and spoilage attributed to microbial activity or other physiological/chemical degradation reactions. The objective of the article is to provide a systematic review of the preservative effect of the available hurdles implemented during processing and packaging of fresh-cut fruits and vegetables, focusing on recent applications aiming at improving product quality and prolonging their limited shelf life.

    这项研究的目的是分析在单足位置有或没有特定优势腿的情况下行走和跨栏的人的身体平衡控制。这项研究涉及28名体育学生。在以下四种条件下用测力板测量压力中心(COP):睁眼单腿站立(左右)和两个上肢位置(手臂以特定的跨栏技术方式或在身体旁边)。在四种条件下,分别对COP的五个参数在内侧-外侧(ML)和前后(AP)方向进行了重复测量方差分析(ANOVA)。在单腿位置,没有优势小腿的运动员比优势小腿的运动员有更好的身体平衡。跨栏时,上肢的位置会影响身体的位置。接受上肢的正确位置有助于保持平衡(克服障碍时)。在障碍中,应改善上肢的位置,以保持姿势稳定性,并将此功能保存在要求更高的姿势任务中。
    The purpose of this study was to analyze the body balance control of people walking and hurdling with or without a specific dominant leg in a monopodal position. This study involved 28 physical education students. The center of pressure (COP) was measured with a force plate under four conditions: single-leg standing (right and left) with eyes open and two upper limb positions (the arms were positioned in either a specific hurdle technique manner or alongside the body). A repeated measures analysis of variance (ANOVA) was conducted separately for five parameters of the COP in the medial-lateral (ML) and anterior-posterior (AP) directions under the four conditions. In the single-leg position, athletes without a dominant lower leg had better body balance than those with a dominant lower leg. The position of the upper limbs influenced the body position when hurdling. Accepting the correct position of the upper limbs helped to maintain balance (when overcoming hurdles). In hurdles, the position of the upper limbs should be improved to maintain postural stability and save this function for more demanding postural tasks.

    The effect of the inclusion of a high hurdle 13.72 m after the start line on elite sprint start and initial acceleration technique has yet to be investigated or understood. This highly novel study addresses that lack of information in an exceptional manner, through detailed biomechanical analysis of the world\'s best sprint and hurdle athletes, with data collected in situ at the 2018 IAAF World Indoor Championships, held in Birmingham, UK. High speed videos (150 Hz) were compared for eight sprinters and seven hurdlers for the start and initial acceleration phase of the finals of the men\'s 60 m and 60 m hurdles. Temporal and kinematic data were supplemented by vector coding analysis to investigate mechanisms by which these world-class athletes translate their centres of mass (CM) up to the fourth touchdown post-block exit. The sprinters and hurdlers coordinated their lower limb and trunk movement in a similar manner throughout the start and initial acceleration phases, which contributes new conceptual understanding of the mechanisms that underpin start and initial acceleration performance. Differences between groups were initiated from block set-up, with the hurdlers utilising a larger block spacing, but with the front block nearer to the start line than sprinters. Even after accounting for stature, the biggest differences in the raising of the CM occurred during the block phase, with hurdlers greater than sprinters (difference in vertical CM displacement scaled to stature = -0.037, very large effect size). Subsequent flight phases showed the biggest differences in the translation of the CM, in part due to longer flight times in the hurdlers, whilst the techniques of the two groups generally converged during the ground contact phases of initial acceleration. In highlighting that similar techniques are used by world-class sprinters and hurdlers, despite differing task constraints, this study has provided invaluable insights for scientists, coaches, and athletes, that will inform further developments in understanding and practice across both sprints and hurdles.
