摘要： 结合竞争力相关指标与灰色关联分析法就中国与其他金砖国家的农产品竞争力进行比较研究,结果表明:在五个金砖国家中,我国农产品国际市场占有率排第二,贸易竞争优势指数与显性比较优势指数均位列第四,出口增长优势指数则位列第五,总体竞争力较弱;我国农产品的各竞争力指标与世界农产品出口的关联度总体偏低。要增强我国农产品贸易竞争力,建议鼓励科技创新、适度规模经营、培育新型农业经营主体、加大政策支持以及构建良好的消费环境等措施。

摘要： Purpose: An ill-defined proportion of patients undergoing urethroplasty fail to experience improvement in lower urinary tract symptoms (LUTS) despite being stricture-free. We aim to identify the incidence, associations and causes of "LUTS failure" after urethroplasty. Materials and Methods: Patients undergoing urethroplasty over a 6-year period were offered enrollment in a prospective study examining urinary function after urethroplasty. Patients were assessed preoperatively and 6 months postoperatively using the International Prostate Symptom Score (IPSS) and cystoscopy. "LUTS failure" was defined as <= 3-point improvement in IPSS despite an anatomically successful urethroplasty. Multivariable logistic regression was utilized to evaluate the association between patient factors and "LUTS failure." Results: Of 365 patients meeting inclusion criteria, mean postoperative IPSS (20.3 vs. 5.4, p<0.0001) and median urinary quality of life (UQOL;5 vs. 1;p<0.0001) were significantly improved. Despite being stricture-free, 7.7% of patients reported "LUTS failure" and 10.1% reported UQOL nonresponse. On multivariable logistic regression, increasing age (OR 1.04, 95% CI 1.01-1.06;p=0.006) and hypospadias (OR 18.2, 95% CI 2.1156.0;p=0.008) were associated with "LUTS failure," while stricture location (p=0.76), length (p=0.14), previous urethroplasty (p=0.96), failed endoscopic treatment (p=0.17), type of urethroplasty (p=0.93) and other etiologies were not. Qualitatively, the most likely causes of "LUTS failure" were detrusor underactivity (39.3%), overactivity (21.4%), pelvic floor dysfunction (21.4%) or benign prostatic hyperplasia (14.3%). Only increasing age was associated with UQOL nonresponse (OR 1.03, 95% CI 1.01-1.07;p=0.02). Conclusions: While many patients experience improved voiding function after urethroplasty, 7.7% experience "LUTS failure" and 10.1% report UQOL nonresponse. Both occurrences are independently associated with increasing patient age and most commonly

摘要： Health care professionals and the institutions in which they work are being stretched to their limits amidst the current COVID-19 pandemic. At the same time, a second longstanding pandemic has been brought to the fore: the entrenched system of racial injustice and oppression. The first pandemic is new, and to date, substantial resources have been allocated to urgently addressing its mitigation;the second has a long history with inconsistent attention and resources but has recently been spotlighted more intensely than at any time in the nation's recent past. The authors contend that these 2 simultaneous pandemics have brought forth the need for institutions in the United States to make a renewed commitment to respect, wellness, diversity, and inclusion. While investment and leadership in these domains have always been essential, these have largely been viewed as a "nice-to-have" option. The events of much of 2020 (most notably) have illustrated that committing to and investing in policies, programs, centers, and leadership to drive change in these domains are essential and a "need-to-have" measure. The authors outline the necessity of investing in the promotion of cultures of inclusive excellence at both individual and organizational levels to coordinate a united response to the simultaneous pandemics. It is in the interests of health care systems to consider the wellness of the workforce to overcome the longer-term economic, systemic, and social trauma that will likely occur for years to come at both the individual and institutional levels. Maintaining or augmenting investment is necessary despite the economic challenges the nation faces. Now is the time to cultivate resilience and wellness through a renewed commitment to cultures of respect, diversity, and inclusion. This commitment is urgently needed to support and sustain the health care workforce and maintain outstanding health care systems for future generations.

摘要： Introduction Out of hours (OOHs) primary care is a critical component of the acute care system overnight and at weekends. Referrals from OOH services to hospital will add to the burden on hospital assessment in the ED and on-call specialties. Methods We studied the variation in referral rates (to the ED and direct specialty admission) of individual clinicians working in the Oxfordshire, UK OOH service covering a population of 600 000 people. We calculated the referral probability for each clinician over a 13-month period of practice (1 December 2014 to 31 December 2015), stratifying by clinician factors and location and timing of assessment. We used Simul8 software to determine the range of hospital referrals potentially due to variation in clinician referral propensity. Results Among the 119 835 contacts with the service, 5261 (4.4%) were sent directly to the ED and 3474 (3.7%) were admitted directly to specialties. More referrals were made to ED by primary care physicians if they did not work in the local practices (5.5% vs 3.5%, p=0.011). For clinicians with >1000 consultations, percentage of patients referred varied from 1% to 21% of consultations. Simulations where propensity to refer was made less extreme showed a difference in maximum referrals of 50 patients each week. Conclusions There is substantial variation in clinician referral rates from OOHs primary care to the acute hospital setting. The number of patients referred could be influenced by this variation in clinician behaviour. Referral propensity should be studied including casemix adjustment to determine if interventions targeting such behaviour are effective.
