Penicillin and ampicillin drugs are approved for use in food animals in the United States to treat, control, and prevent diseases, and penicillin is approved for use to improve growth rates in pigs and poultry. This article considers the possibility that such uses might increase the incidence of ampicillin-resistant Enterococcus faecium (AREF) of animal origin in human infections, leading to increased hospitalization and mortality due to reduced response to ampicillin or penicillin. We assess the risks from continued use of penicillin-based drugs in food animals in the United States, using several assumptions to overcome current scientific uncertainties and data gaps. Multiplying the total at-risk population of intensive care unit (ICU) patients by a series of estimated factors suggests that not more than 0.04 excess mortalities per year (under conservative assumptions) to 0.14 excess mortalities per year (under very conservative assumptions) might be prevented in the whole U.S. population if current use of penicillin drugs in food animals were discontinued and if this successfully reduced the prevalence of AREF infections among ICU patients. These calculations suggest that current penicillin usage in food animals in the United States presents very low (possibly zero) human health risks. 相似文献

代际流动表可以统计子代与其父代社会地位配对数据的交互频数,反映了社会资源占有的优劣势在父子两代人之间的比较。对财富、阶级、特权等社会基本特征演变的实证考察,均依赖于代际流动表的量化分析。对数线性模型是流动表建模分析的基本工具,通过对列联表单元格频数进行拟合,可以识别流动表行分类与列分类之间的强弱交互效应,刻画父子社会地位间的交互结构。本文利用复杂网络社区发现算法分析父子社会地位的关联结构,针对简约对数线性模型拟合精度不够的问题,提出一种新的建模思路:利用社区发现算法对简约对数线性模型的残差列联表进行关联关系挖掘,将发现的社区效应作为附加参数约束引入原对数线性模型,以改善数据的拟合情况。由于该方法只在原简约对数线性模型中增加了一个参数约束,因此仍可以保证建模结果的简洁性及理论意义,同时社区效应补充了原对数线性模型对经验数据结构的解读。论文用此方法对来源于中国综合社会调查数据的经验代际职业流动表进行建模分析,较好地解释了子代职业阶层与父代职业阶层间的关联模式。 相似文献

This paper studies the role of emotions in creating spectacular revolt situations. We underline the travelling competence of sentiments and their power in crafting trans-local moments of embodied resistance. In contemporary Moroccan society, the adaptation of the Bouazizian style of protest has been a reaction to the prevailing feelings of worthlessness gripping the common citizen. The images of wasted beings in the post-2011 atmosphere have been associated with instances of social insurgence, by individuals who attempt self-immolation, or citizens treated by figures from the centre (e.g. police, public figures) in a way that inculcate in them powerful feelings of abjection, after which they feel irreparably delinked from their sense of humanity. This paper seeks to demonstrate how practices of al-hogra (humiliation) have produced cultural forms of abjection that could also be traced in the way common people inferiorize one another in everyday life through the use of a terminology of trash. By disclosing people’s non-subtle armaments of protest (i.e. self-immolation), we contend that resistance and its various trances, as well as the emotions that prompt them, have their origin in the reality of the body, realistic visions of the body owner and his/her awareness of the potential for realization (through it). Hence we will examine how vulnerable people manipulate the three conditions of corporeality, corporealism and corporealization, to subvert the humiliation and symptoms of social death imposed on them by the regime. 相似文献

Objective: This study set out to assess effects of testosterone replacement therapy (TRT) on parameters of metabolic syndrome and vascular function in obese hypogonadal males with type 2 diabetes mellitus (DM2).Study design: Fifty-five obese hypogonadal diabetic males on oral hypoglycemic treatment were enrolled into this one-year, double-blind, randomized, placebo-controlled clinical study. Group T (n?=?28) was treated with testosterone undecanoate (1000?mg i.m. every 10?weeks) while group P (n?=?27) received placebo.Methods: Anthropometrical and vascular measurements – flow-mediated dilatation (FMD) and intima media thickness (IMT) – biochemical and hormonal blood sample analyses were performed at the start of the study and after one year. Derived parameters (BMI, HOMA-IR, calculated free testosterone (cFT) and bioavailable testosterone (BT)) were calculated.Results: TRT resulted in reduction of HOMA-IR by 4.64?±?4.25 (p?.001), HbA1c by 0.94?±?0.88% points (p?.001), and an increase in FMD by 2.40?±?4.16% points (p?=?.005).Conclusion: TRT normalized serum testosterone levels, improved glycemic control and endothelial function while exerting no ill effects on the study population. 相似文献

Health and hospital system reforms prioritise efficiency. However, initiatives can impact on people with new or existing disabilities who require time to maximise functional independence. With greater demands for shorter hospital stays social workers face increasing pressure to facilitate discharge. This paper reports findings from research identifying factors contributing to extended stays for adults with disabilities. We sought to better understand patient characteristics and discharge planning challenges by analysing a clinical dataset of 80 patients and qualitative interviews with five experienced hospital social workers. Three key factors are identified: issues around rehabilitation services; assessment and planning for community care; and availability of and access to discharge options. Strategies to reduce length of stay are reported. We argue that building collaborative partnerships and working across multiple, complex systems and disciplines are vital to ensure these patients access appropriate community-based resources within the current health reform environment. 相似文献

Introduction: Metabolic syndrome (MetS) is a constellation of interrelated risk factors of metabolic origin. Some studies suggest a possible link between low total testosterone (TT) levels and the presence of MetS.Aim: To analyze the strength and independence of associations between TT and MetS components in non-diabetic men.Methods: In this cross-sectional study, 143 non-diabetic men older than 40 were analyzed.Main outcomes measure: Blood samples were collected to evaluate metabolic profile and TT levels. MetS was defined as the presence of three or more of the following characteristics: fasting blood glucose levels?≥?100?mg/dL, triglyceride?≥?150?mg/dL, HDL-c?40?mg/dL, hypertension or blood pressure?≥?130/85?mmHg, and waist girth?>?102?cm.Results: Mean age of the study population was 61.5?±?8.61 years old. MetS was present in 47.9% of the individuals. Thirty-four men had low TT and MetS was observed in 23 (70%) against 50 (46%) in those with normal TT (≥?300?ng/dL) (OR 4.94, p?0.01), adjusted to confounder’s factors. In multiple linear regression analysis, only waist circumference (Beta: ?0.395; p?=?0.03) and HDL-c (Beta: 0.19; p?=?0.04) remained significantly correlated with TT levels.Conclusions: Low TT levels were associated with MetS diagnosis. Abdominal obesity was the MetS component independently correlated to low TT levels. 相似文献

Little is understood about the scope of information and communication technology (ICT) use in practice for agency-based social work professionals, and still less is known about how such practitioners acquire and avail themselves of opportunities to learn about ICT tools. This study asked a sample of social work field supervisors (n?=?371) to describe their personal and professional ICT use, to rank the technological sophistication of their agency, to describe the barriers and facilitators to ICT use in their organizations and to operationalize environmental opportunities for acquiring new skills and knowledge. The authors examine factors that may influence technology use: asking if organizational culture is related to uptake in the professional context, and if self-reported individual resistance to innovation and change can explain voluntary adoption of ICT tools. The results offer a portrait of how agency-based social workers are using technology in personal and professional life, describe how these supervisors learn about developing technologies for practice, and highlight the gaps in technology infrastructures among agencies, pointing to directions for further exploration. 相似文献

Social workers within child protection services report that families marked by high levels of conflict between separated parents are among the most challenging cases to handle. Few studies however have focussed on how social workers themselves experience and meet with parents involved in hostile martial interactions. This article reports on a qualitative study involving 31 social workers and provides an analysis of their experiences and dilemmas in working with such families. Findings demonstrate that social workers struggle to find ways to help high‐conflict families and often find themselves at an impasse. Parents involved in such conflict are highly resistant to change, and social workers struggle to engage with them over concerns about their children. Furthermore, findings suggest that social workers lack organizationally allotted time to assist the parents. I conclude by discussing ways in which emotional support, empowering interventions, and strength‐based approaches enable social workers to manage relationships with high‐conflict families. More research on this topic is needed to support and promote better practices for social workers to be more effective in assisting high‐conflict families. 相似文献

This article explores a surprising and seemingly mundane organizational practice: passing notes during professional meetings. Based on 34 in‐depth interviews with women in a hyper‐masculine organization — the Israeli military — this study focuses on what I term gendered practices of public ambiguity. It demonstrates how these practices shed light on three interrelated paths to power at work: (i) practices of public intimacy between men; (ii) practices of women's degradation by men; and (iii) practices of recognition claims by women. The tension between the publicity inherent in the routine passing of notes and the ambiguity of their contents calls for a more nuanced theorization of gendered power practices, which transcends the accepted dichotomy of doing and undoing gender, reproducing or challenging the symbolic gender order. The findings show that gendered micro‐practices can become polysemic symbolic spaces in which women redirect the flow of power, if only temporarily and locally, and turn it into a multidirectional and multi‐agentic resource. The conceptual contribution of these findings is discussed in terms of the positioning of women in hyper‐masculine environments as pragmatic subjects who (re‐)construct mechanisms of power out of the restricted repertoire available to them. 相似文献
