    医疗保健系统中的预算限制导致了成本效益阈值(CET)的普及,以实现资源的有效分配。就阈值而言,与QALY相比,能力方法因其潜在的更丰富的评估能力而受到赞誉。广泛的研究,然而,仍然有限。
    这项研究估计了一年的全部能力(YFC)的货币价值,并将其与匈牙利人口的QALY的货币价值进行了比较。数据是从一个大的,横截面,关于匈牙利成年人口的代表性在线调查。应用福祉评估方法,健康,能力,然后将收入与幸福感进行回归,以估计QALY和YFC控制性别的“影子价格”,年龄,employment,教育,婚姻和社会支持。要检查“核心”回归系数,进行了稳健性检查。
    健康(VAS)和能力(ICACAP-A)对主观幸福感有积极而显着的影响。一个QALY和一个YFC的货币价值分别为39459欧元和58148欧元。
    这些工具为确定某些疾病的“补偿收入”提供了一种系统的方法,残疾和疼痛程度。能力方法比QALY更广泛。
    UNASSIGNED: Budget constraints in health-care systems have led to the popularity of Cost Effectiveness Thresholds (CET) to achieve efficient allocation of resources. The capability approach has been hailed for its potentially richer evaluative capabilities compared to the QALY in terms of thresholds. Extensive research, however, is still limited.
    UNASSIGNED: This study estimated the monetary value of a year in full capability (YFC) and compared it to monetary value of a QALY for the Hungarian population. Data was collected from a large, cross sectional, representative online survey on the adult Hungarian population. Applying the wellbeing valuation method, health, capability, and income were then regressed against wellbeing to estimate \'shadow prices\' for one QALY and YFC controlling for gender, age, employment, education, marital and social support. To examine \'core\' regression coefficients, a robustness check was conducted.
    UNASSIGNED: Health (VAS) and capability (ICECAP-A) had a positive and significant effect on Subjective Well-Being. The monetary values of one QALY and one YFC were 39 459 EUR and 58 148 EUR respectively.
    UNASSIGNED: These tools provide a systematic approach to determining \'compensating income\' for certain illnesses, disabilities and levels of pain. The capability approach shown to be broader than the QALY.

    Desho草(狼尾草)是一种重要的饲料草。然而,缺乏有关其生产的信息。进行这项研究以评估在不同切割高度(CH)下收获的Desho草的牧草干物质产量和营养价值,在埃塞俄比亚中部高地两个不同地点的雨水条件下,持续了两年。处理(T1-T8)为:50、60、70、80、90、100、110和120厘米的切割高度,分布在随机完整的区组设计中,重复三次。草的根裂以3m×4m(12m2)的地块大小种植,行间和行内间距为0.5m×0.25m。在这两个地方,多年来,在切割高度之间观察到显着差异。切割高度与位置的相互作用,按年份划分的位置也很重要。切割高度之间的相互作用,location,年份微不足道。随着植物高度的增加,NLPP达到了最高(每株植物的叶子数),而不同处理下,单株分耕数(NTPP)差异不显著。干物质产量(DMY)随着CH的增加而线性增加(Holetta从12.2到20.1tha-1,和4.2至11.4tha-1atKulumsa)。随着采伐高度的增加,草的灰分和粗蛋白(CP)含量降低。CH的增加增加了中性洗涤纤维(NDF)的纤维含量,酸性洗涤剂纤维(ADF),和酸性洗涤剂木质素(ADL),导致体外干物质消化率(IVDMD)降低。我们建议在80-90厘米的高度管理desho草,以获得最佳的干物质产量和营养价值,以供埃塞俄比亚中部高地和主要种植区的小农和以市场为导向的牲畜生产者使用。
    Desho grass (Pennisetum glaucifolium Trin) an important fodder grass. However, information on its production is lacking. This study was carried out to evaluate the forage dry matter yield and nutritive value of Desho grass harvested at different cutting heights (CH), under rain-fed conditions in two different sites in central highlands of Ethiopia for two years. The treatments (T1-T8) were: 50, 60, 70, 80, 90, 100, 110, and 120 cm cutting heights, distributed in a randomized complete block design with three replications. The root splits of the grass were planted in a 3 m × 4 m (12 m2) plot size with 0.5 m × 0.25 m inter and intra-row spacing. In the two locations, over the years, significant differences were observed among cutting heights. The interaction of cutting heights by locations, and location by years were also significant. The interaction among cutting height, location, and year was insignificant. The highest (number of leaves per plant) NLPP was attained as the plant height advance, while the number of tillers per plant (NTPP) showed non-significant differene in different treatments. The dry matter yield (DMY) increased linearly with an increase in CH (ranging from 12.2 to 20.1 t ha-1 at Holetta, and 4.2 to 11.4 t ha-1at Kulumsa). The grass\'s ash and crude protein (CP) contents decreased as the cutting height increased. An increase in CH increased the fiber content Neutral detergent fiber (NDF), acid detergent fiber (ADF), and Acid detergent lignin (ADL), resulting decrease in in-vitro dry matter digestibility (IVDMD). We recommend that desho grass be managed at 80-90 cm height resulting in optimum dry matter yield and nutritive value for use in smallholder farmers and market-oriented livestock producers of the central highlands of Ethiopia and major growing areas.

    本研究的目的是使用2004年至2019年期间38个父系和287个水坝出生的963个孩子的系谱记录来估计Beetal山羊的近交系数及其对各种生长性状的影响。在动物模型下获得每个个体的近交系数。近亲繁殖的影响以及其他固定影响,如出生年份,孩子的性别,出生类型,和大坝的体重在开玩笑的增长特征,即。,出生体重(BWT),3(WT3),6(WT6),9(WT9),使用最小二乘分析研究了12个月(WT12)的年龄。此外,在相同模型下研究了直至断奶年龄(90天)的平均日增重和Kleiber比率。在研究期间,总体近交系数的大小较低(1.42%),范围为0至25%。在研究群体中观察到多年来平均近交系数(%)的显着增加(P<0.05)。虽然,最小二乘模型下各因素对生长性状影响显著(P<0.05),近交目标性状的回归不显著(P>0.05),回归范围为-0.06~0.04。目前的发现表明,Beetal山羊的生长性状中没有近交抑制。然而,由于近亲繁殖(%)仅在最近几年提高,必须采取科学努力,通过尽早引进新的种质来避免资源种群的近亲繁殖。
    The purpose of the present study was to estimate the inbreeding coefficient and its effects on various growth traits in Beetal goat using pedigree records of 963 kids born to 38 sires and 287 dams over the period of 2004 to 2019. The inbreeding coefficients for each individual were obtained under animal model. The effects of inbreeding along with other fixed effects such as year of birth, sex of kid, type of birth, and dam\'s weight at kidding on growth traits viz., weight at birth (BWT), 3 (WT3), 6 (WT6), 9 (WT9), and 12 (WT12) months of age were studied using least-squares analysis. Additionally, average daily gain and Kleiber ratio up to weaning age (90 days) were studied under the same model. The overall inbreeding coefficient was low in magnitude (1.42%) and ranged from 0 to 25% over the study period. The significant (P < 0.05) increase in average inbreeding coefficient (%) over the years was observed among the studied population. Although, the effects of various factors had significant (P < 0.05) influence on growth traits under least-squares model, the regression of targeted traits on inbreeding were non-significant (P > 0.05) and the same ranged from - 0.06 to 0.04. The present findings indicated that there was no inbreeding depression among the growth traits of Beetal goat. However, as inbreeding (%) raised in recent years only, the scientific efforts must be taken to avoid inbreeding at resourced population by introducing new germplasms at earliest.

    汞(Hg)是野生动物和人类中众所周知的毒物。据报道,加利福尼亚中部港口海豹Phocavitulinarichardii的总汞浓度很高([THg])。我们评估了存在/不存在早期出生被毛(胎毛)的影响,年(2012年至2017年),性别,绞合位置,和营养生态(13C和15N值)在加利福尼亚中部沿海的头发[THg]上。还检查了[THg]对幼犬在康复中的生长速率和释放概率的影响(例如,成功的康复)。[THg]范围为0.46-81.98mgkg-1dw,15N和13C的范围为13.6-21.5‰,和-17.2至-13.0‰,分别。搁浅位置,Year,羊毛囊的存在是解释[THg]变化的重要因素。来自索诺玛和圣马特奥县的海豹比其他地方的海豹更高。带有全部或部分羊毛涂层的密封件具有较低的[THg]。2016年和2017年的海豹比2015年的海豹更高。头发[THg]超过了毒性阈值的下限和上限(每年>20mgkg-1(5.88%至23.53%);>30mgkg-1(0%至12.31%)),从2015年到2016年明显增加。2017年的幼犬在20mgkg-1以上的优势比明显高于2015年的幼犬,2016年的幼犬的优势比明显高于2013年和2015年的幼犬(使用30mgkg-1时相似)。索诺玛县的幼犬在20mgkg-1以上的羊毛中[THg]的比值比最高。15N值在2015-2017年较高,特别是相对于2014年,可能与厄尔尼诺事件有关。[THg]不是圈养释放概率和质量特异性增长率的良好预测指标。鉴于超过阈值的样本百分比相对较高,因此有必要对海豹中[THg]的时间趋势进行进一步调查,特别是在最近的抽样年份。
    Mercury (Hg) is a well-known toxicant in wildlife and humans. High total Hg concentrations ([THg]) have been reported in central California harbor seals Phoca vitulina richardii. We evaluated the effects of presence/absence of early natal coat (lanugo), year (2012 to 2017), sex, stranding location, and trophic ecology (ẟ13C and ẟ15N values) on hair [THg] along coastal central California. Also examined were [THg] effects on growth rates of pups in rehabilitation and probability of release (e.g., successful rehabilitation). The [THg] ranged from 0.46-81.98 mg kg-1 dw, and ẟ15N and ẟ13C ranged from 13.6-21.5‰, and -17.2 to -13.0‰, respectively. Stranding location, year, and presence of lanugo coat were important factors explaining variation in [THg]. Seals from Sonoma and San Mateo County had higher [THg] than other locations. Seals with full or partial lanugo coat had lower [THg]. Seals from 2016 and 2017 had higher [THg] than those from 2015. Hair [THg] exceeded lower and upper toxicological thresholds (>20 mg kg-1 by year (5.88% to 23.53%); >30 mg kg-1 (0% to 12.31%)) with a pronounced increase from 2015 to 2016. Pups in 2017 had significantly higher odds ratio of [THg] above 20 mg kg-1 than pups of 2015, and pups in 2016 had significantly higher odds ratio than those from 2013 and 2015 (similar when using 30 mg kg-1). Pups in Sonoma County had the highest odds ratio for [THg] in lanugo above 20 mg kg-1. ẟ15N values were higher in 2015-2017, particularly relative to 2014, probably associated with the El Niño event. The [THg] was not a good predictor for probability of release and mass-specific growth rates in captivity. Further investigation of temporal trends of [THg] in harbor seals is warranted given the relatively high percentage of samples exceeding threshold values, particularly in the most recent sampling years.

    背景:医学培训可能会给学生带来很大压力,并对他们的心理健康产生负面影响。对这一问题来说,重要的是医学生使用的应对策略(及其前身)的类型,这只是在有限的程度上被描述。对这些现象的更好理解可以进一步阐明支持医学生健康和福祉的方法。因此,我们试图确定医学生对压力的各种应对反应的使用,以及他们的性别和学习年份如何影响这些行为。
    方法:共有400名萨斯喀彻温大学的医学生被邀请完成一项在线调查。使用简短的COPE清单,我们评估了学生报告使用各种适应性和适应不良应对策略的情况。进行了描述性和比较性统计,包括多变量方差分析,探讨性别和年份如何影响应对策略。
    结果:参与率为49%(47%为男性,53%为女性)。总的来说,学生的应对策略大多是适应性的,尽管有少数例外。女性使用更多的行为脱离接触,而男性使用较少的情感和工具支持。此外,第三年比其他任何一年的学生都使用更多的否认来应对压力。
    结论:虽然很少有研究报告对医学生应对有显著的社会人口统计学影响,我们的发现提高了男性和女性在医学院采取不同应对策略的可能性,第三年的临床学习环境可能会引发更多功能失调的应对,与临床前阶段的培训相比。讨论了这些结果的潜在解释和含义。
    BACKGROUND: Medical training can be highly stressful for students and negatively impact their mental health. Important to this matter are the types of coping strategies (and their antecedents) medical students use, which are only characterized to a limited extent. A better understanding of these phenomena can shed additional light on ways to support the health and well-being of medical students. Accordingly, we sought to determine medical students\' use of various coping reactions to stress and how their gender and year of study influence those behaviours.
    METHODS: A total of 400 University of Saskatchewan medical students were invited to complete an online survey. Using the Brief COPE inventory, we assessed students\' reported use of various adaptive and maladaptive coping strategies. Descriptive and comparative statistics were performed, including multivariate analysis of variance, to explore how gender and year influenced coping strategies.
    RESULTS: The participation rate was 49% (47% males and 53% females). Overall, the students\' coping strategies were mostly adaptive, albeit with a few exceptions. Females used more behavioural disengagement, while males used less emotional and instrumental support. Additionally, third years used more denial to cope with stress than students in any other year.
    CONCLUSIONS: While few studies report significant sociodemographic effects on medical student coping, our findings raise the possibility that males and females do engage in different coping strategies in medical school, and that the clinical learning environment in third year may provoke more dysfunctional coping, compared to pre-clinical stages of training. Potential explanations and implications of these results are discussed.

    Processing quality of winter-wheat is affected by genotype, environmental conditions, and crop husbandry practices. In the present study, a data set of 17 quality-related traits for 211 main winter-wheat varieties in China during 2006 to 2018 was extracted from China Wheat Quality Report. Analysis was carried out to evaluate the quality status and variations, to reveal correlation between quality-related traits, as well as to identify key influencing factors. Results indicated that the quality indicators of medium-gluten or medium-strong-gluten wheat varieties were acceptable, whereas those of weak- and strong-gluten wheat varieties were far below national standard, especially hardness index (HI), crude protein content (CPC), wet gluten content (WG), and water absorption for weak-gluten wheat and sedimentation value (SV), stability time (ST), and stretch area (SA) for strong-gluten wheat, respectively. Correlation analysis showed that WA, WG, development time, HI, CPC, falling number, ST, and tractility directly affected the overall quality of winter-wheat. CPC, SV, and WG in medium-gluten wheat had no significant correlation with the processing quality of noodles score, whereas gluten index significantly correlated with noodle score (P < 0.001). This implied that protein quality might play a more important role than protein quantity in determining medium-gluten wheat quality. Furthermore, analysis of variance showed that genetic characteristics (cultivars) had significant influences on the restriction indexes (SV, ST, and SA) of strong-gluten wheat, whereas genetic characteristics, environment conditions, and crop growing practices (cultivars, locations, and years) significantly affected the restriction indexes (HI, CPC, WG, and WA) of weak-gluten wheat. The results suggest that improvement of Chinese strong-gluten wheat should mainly focus on cultivating new varieties. As to weak-gluten wheat, cultivation and husbandry practices should be paid more attention to limit undesired high grain protein content.

    This study aims to compare the internal chemical composition and appearance indifferent growth patterns and years of Saposhnikovia divaricata decoction pieces,which was applied to explore the effect of growth patterns and years on its quality. The appearance characteristic data of 55 batches of different growth patterns and years of S. divaricata were collected using PANTONE color card.High performance liquid chromatography( HPLC) was used to determine the contents of prim-O-glucosyl-cinmifugin,cimifugin,4-O-β-D-glucosyl-5-O-methylvisamminol and sec-O-glucosylhamaudol. The content of alcohol soluble extract and water-soluble extract were determined by hot-dip method. The content of volatile oil was determined by steam distillation. The correlation between growth patterns and years and the contents of 4 chromones,extracts and volatile oil were analyzed by modern statistical methods. Also,the method of comprehensively evaluating the quality of Chinese herbal pieces was developed by combining the growth patterns and years,appearance and chemical indexes. MTT assay was used to evaluate the effects on the survival rate of RAW264. 7 cells at four different concentrations of chromones and LPS was used to stimulate well-growing RAW264. 7 cells to establish an inflammatory model. The contents of NO and TNF-α in cell supernatant were detected by NO test kit and ELISA method. The contents of alcohol soluble extracts and water-soluble extracts in different growth patterns and years are: wild productsperennial cultivation>annual cultivation; the contents of four chromones are: wild products>perennial cultivation and annual cultivation. There was no significant difference between the sum of the two indexes in the Pharmacopoeia of perennial cultivation and wild products. 4 chromones showed no toxicity to RAW264. 7 cells at 5 mg·L-1. The release of NO and TNF-α was inhibited by 4 chromones and the anti-inflammatory effect of cimifugin was the best. In summary,there are obvious differences in appearance characteristics,internal quality and effects between different growth patterns and years. It showed that the wild products were superior to the perennial cultivation and the perennial cultivation was superior to the annual cultivation. In order to alleviate the shortage of wild S. divaricata resources,it is suggested that the Chinese Pharmacopoeia standard should increase the character of decoction pieces of perennial cultivation,and properly raise the limit requirement of the sum of the two indexes in the Chinese Pharmacopoeia to ensure the clinical demands and effect.

    The present study determined trends in the isolation of bacterial pathogens in milk samples submitted from clinical mastitis buffaloes at the University mastitis laboratory during 2007 to 2016. Culture results (n = 3945) were classified into six categories (Staphylococcus spp., 28.7%; Streptococcus spp., 1%; Corynebacterium spp., 1.1%; gram-negative organisms, 3.2%; others including mixed growths, 3.3%; and no growth, 62.7%). Overall, culture results were significantly associated with year (χ2 = 112.28; df = 10; P < 0.001) and season (χ2 = 136.03; df = 20; P < 0.001). From 2007-2009 to 2013-2016, the isolation of Staphylococcus spp. increased from 28.2 to 48.4%, while isolation of Streptococcus spp. (50 to 20%) and Corynebacterium spp. (65.1 to 16.3%) decreased. The proportion of samples characterized as no growth increased from 26.4% (2007-2009) to 46.3% (2013-2016). Further, the proportion of clinical mastitis cases increased over the study years (goodness-of-fit χ2 = 59; df = 2; P < 0.001). With respect to season, the proportion of Staphylococcus spp. (30.6%; 346/1132), Corynebacterium spp. (48.8%; 21/43), and gram-negative bacteria (55.9%; 71/127) were more associated with the monsoon, and that of Streptococcus spp. (47.5%; 19/40) with the winter. Seasonal effects were also observed on the occurrence of clinical mastitis cases; comparatively, more clinical mastitis cases (35.6%; 523/1473) were observed during the monsoon season (goodness-of-fit χ2 = 276.7; df = 4; P < 0.001) as compared with other seasons. The present study concludes that Staphylococcus spp. are the major cause of intramammary infections in buffaloes with clinical mastitis, demanding more studies regarding its epidemiology and pathogenicity. Also, more efforts are needed in the prevention and control of clinical mastitis in buffaloes, especially, during the monsoon season.

    Since maize silage is an important forage in cattle nutrition, it is important to know its nutritive value. Much effort is put into breeding maize, and several new varieties are introduced on the market every year. This requires periodical analyses of the nutritive value of current maize varieties for the formulation of cattle rations. The aim of this study was to examine the nutritive value of whole crop maize silage (WCMS) from nine maize varieties in 3 consecutive years. For the analysis of nutrient composition and ruminal degradability of organic matter (OM), crude protein (CP), neutral detergent fibre (aNDFom) and non-fibre carbohydrates (NFC), varieties were harvested at three harvest dates (50%, 55% and 60% dry matter content in ear). Due to capacity limitations, the digestibility of WCMS was tested only for the middle harvest date. The CP and acid detergent fibre (ADFom) content was affected (p < 0.05) while aNDFom and NFC content was not influenced by variety. With advancing maturity, CP, aNDFom and ADFom content declined while NFC content increased. Variety influenced effective ruminal degradability (ED) of nutrients, except for CP. The ED of all examined nutrients decreased as maturity advanced from first to third harvest date. Digestibility of OM, ADFom and NFC was significantly and digestibility of aNDFom was tendentially (p = 0.064) influenced by variety. Additionally, an effect of year and a harvest date × year interaction was found for almost all examined parameters. In conclusion, variety, harvest date and year influence the nutritive value of WCMS. A comparison with earlier studies shows that current varieties have a higher fibre digestibility and a slower-ripening stover compared to older varieties.
