We aimed to assess the extent to which general practitioners follow the recommendations of the French National Authority for Health in prescribing chest radiography. Methodology: We conducted a retrospective analysis study, in two radiology centers belonging to the same group in Saint-Omer and Aire-sur-la-Lys, of requests for chest radiography sent by general practitioners over the winter period between December 22, 2013, and March 21, 2014, for patients aged over 18 years. Results: One hundred and seventy-seven requests for chest X-rays were analyzed, 71.75% of which complied with recommendations. The most frequent reason was the search for bronchopulmonary infection, accounting for 70.08% of prescriptions, followed by 11.2% for requests to rule out pulmonary neoplasia, whereas the latter reason did not comply with recommendations. Chest X-rays contributed to a positive diagnosis in 28.81% of cases. The positive diagnosis was given by 36.22% of the recommended chest X-rays, versus 10% for those not recommended. Conclusion: In most cases, general practitioners follow HAS recommendations for prescribing chest X-rays. Non-recommended chest X-rays do not appear to make a major contribution to diagnosis or patient management, confirming the value of following the recommendations of the French National Authority for Health.展开更多

This slide, however, can actually act as a form of isolation for the substructure, and as a result, the piers and foundation of most of the bridges on state route 213 suffered minor damage. The exception was the Baihua Bridge, which suffered severe damage. Corresponding seismic design recommendations are presented based on this investigation.展开更多

To convey this concept more appropriately, partial endocrine deficiency in the aging male (PEDAM) was introduced as a term for the phenomenon of hormonal alterations in the aging male. Hormones responsible for some of the manifestations associated with male aging are testosterone, growth hormone, dehydroepiansdrosterone (DHEA), melatonin, thyroid hormones and leptin. Of these, testosterone has been widely investigated and its beneficial and adverse effects on male bodily systems are relatively well established. However, a serious body of confusion and misunderstandings surrounding the diagnosis, treatment and monitoring of men suspected of having androgen deficiency has been raised. Therefore, it is timely to provide practical criteria for diagnosis and treatment to avoid misconception about the use of testosterone in the aging male. To provide an understanding and information of the issues, the following headings are summarized: (1) Important clinical consideration on testosterone supplementation in the aging male; (2) Asian practical recommendations on testosterone supplementation in the aging male.展开更多

The proposed algorithm computes appropriate charging pile locations by: 1) mining user Points of Interest from social network; 2) mining parking sites of vehicle form GPS trajectories and 3) fusing the Points of Interest and parking sites together then clustering the fusions with our improved DBSCAN algorithm, whose clustering results indicates the final appropriate charging pile locations. Experimental results show that our proposed methods are more efficient than existing methods.展开更多

This paper proposes recommendations for probiotics in pediatric gastrointestinal diseases in the Asia-Pacific region. Epidemiology and clinical patterns of intestinal diseases in Asia-Pacific countries were discussed. Evidence-based recommendations and randomized controlled trials in the region were revised. Cultural aspects,health management issues and economic factors were also considered. Final recommendations were approved by applying the Likert scale and rated using the GRADE system. Saccharomyces boulardii CNCM I-745(Sb) and Lactobacillus rhamnosus GG(LGG) were strongly recommended as adjunct treatment to oral rehydration therapy for gastroenteritis. Lactobacillus reuteri could also be considered. Probiotics may be considered for prevention of(with the indicated strains): antibiotic-associated diarrhea(LGG or Sb); Clostridium difficile-induced diarrhea(Sb); nosocomial diarrhea(LGG); infantile colic(L reuteri) and as adjunct treatment of Helicobacter pylori(Sb and others). Specific probiotics with a history of safe use in preterm and term infants may be considered in infants for prevention of necrotizing enterocolitis. There is insufficient evidence for recommendations in other conditions. Despite a diversity of epidemiological,socioeconomical and health system conditions,similar recommendations apply well to Asia pacific countries. These need to be validated with local randomized-controlled trials.展开更多

Therefore, the Paddy Fertilizer Recommendation System (PFRS) application package was designed to aid in the dissemination of fertilizer recommendations for paddy fields. PFRS utilized geographical information system (GIS) ActiveX Controls, enabling the user to select a location of interest linked to a spatial database of paddy field soil characteristics. The application package also incorporated different soil fertilizer recommendation methods, forming a relational database. The application's structure consisted primarily of building database queries using Standard Query Language (SQL) constructed during run-time, based on user provided spatial parameters of a selected location, the type of soil desired and paddy production criteria. PFRS, which was comprised of five modules including: File, View, Edit, Layer and Fertilizer/Model, provided the user with map-based fertilizer recommendations based on selected soil nutrient P and K map layers as well as N characteristics and land use maps.展开更多

Stem cell-based therapy has emerged as a promising approach for prompting cardiac rejuvenation. Various cell types have been tested in the clinical arena, proving consistent safety results. As for efficiency outcomes, contradictory findings have been reported, partly due to inconsistency in study protocols but also due to poor survival, engraftment and differentiation of transplanted cells in the hostile milieu of the ischemic host tissue. Studies have varied in terms of route of delivery, type and dose of implanted stem cells, patient selection and randomization, and assessment of therapeutic effect. Founded on the main achievements and challenges within almost 20 years of research, a number of official documents have been published by leading experts in the field. Core recommendations have focused on developing and optimizing effective strategies to enrich cell retention and their regenerative potential. Issued consensus and position papers have stemmed from an unmet need to provide a harmonized framework for future research, resulting in improved therapeutic application of cell-based therapies for cardiac regeneration and repair.展开更多

New and improved standards ofpeople-oriented care and person-centredness, as well as improved principles ofpreventive screening and guideline development, have been postulated andimplemented in health care systems and cultures. Recommendations addressingscreening for scoliosis differ substantially, in terms of their content, standards ofdevelopment and screening principles. Some countries have discontinued issuingrecommendations. In the last decade, a number of updated and newrecommendations and statements have been released. Systematically developedguidelines and recommendations are confronted by consensus and opinion-basedstatements. The dilemmas and discrepancies prevail. The arguments concentrateon the issues of the need for early detection through screening in terms of theeffectiveness of early treatment, on costs and cost-effectiveness issues, scientificand epidemiologic value of screenings, and the credibility of the sources ofevidence. The problem matter is of global scale and applies to millions of people.It regards clinical and methodological dilemmas, but also the matter of vulnerableand fragile time of adolescence and, more generally, children’s rights. Thedecisions need to integrate people’s values and preferences – screening tests needto be acceptable to the population, and treatments need to be acceptable forpatients. Therefore we present one more crucial, but underrepresented in thediscussion, issue of understanding and implementation of the contemporaryprinciples of person-centred care, standards of preventive screening, andguideline development, in the context of screening for scoliosis.展开更多

文摘Introduction: Chest radiography is the most frequently prescribed imaging test in general practice in France. We aimed to assess the extent to which general practitioners follow the recommendations of the French National Authority for Health in prescribing chest radiography. Methodology: We conducted a retrospective analysis study, in two radiology centers belonging to the same group in Saint-Omer and Aire-sur-la-Lys, of requests for chest radiography sent by general practitioners over the winter period between December 22, 2013, and March 21, 2014, for patients aged over 18 years. Results: One hundred and seventy-seven requests for chest X-rays were analyzed, 71.75% of which complied with recommendations. The most frequent reason was the search for bronchopulmonary infection, accounting for 70.08% of prescriptions, followed by 11.2% for requests to rule out pulmonary neoplasia, whereas the latter reason did not comply with recommendations. Chest X-rays contributed to a positive diagnosis in 28.81% of cases. The positive diagnosis was given by 36.22% of the recommended chest X-rays, versus 10% for those not recommended. Conclusion: In most cases, general practitioners follow HAS recommendations for prescribing chest X-rays. Non-recommended chest X-rays do not appear to make a major contribution to diagnosis or patient management, confirming the value of following the recommendations of the French National Authority for Health.

文摘A field experiment with a split-plot design was carried out at Dongbeiwang Farm in Beijing Municipality to establish reliable N fertilizer recommendation indices for summer maize (Zea mays L.) in northern China using the soil Nmin (mineral N) test as well as the plant nitrate and SPAD (portable chlorophyll meter readings) tests. The results showed that Nmin sollwert (NS) 60 kg N ha-1 at the third leaf stage and N rate of 40 to 120 kg N ha-1 at the tenth leaf stage could meet the N requirement of summer maiz…

文摘This opinion review considers the prevailing question of whether to screen or notto screen for adolescent idiopathic scoliosis. New and improved standards ofpeople-oriented care and person-centredness, as well as improved principles ofpreventive screening and guideline development, have been postulated andimplemented in health care systems and cultures. Recommendations addressingscreening for scoliosis differ substantially, in terms of their content, standards ofdevelopment and screening principles. Some countries have discontinued issuingrecommendations. In the last decade, a number of updated and newrecommendations and statements have been released. Systematically developedguidelines and recommendations are confronted by consensus and opinion-basedstatements. The dilemmas and discrepancies prevail. The arguments concentrateon the issues of the need for early detection through screening in terms of theeffectiveness of early treatment, on costs and cost-effectiveness issues, scientificand epidemiologic value of screenings, and the credibility of the sources ofevidence. The problem matter is of global scale and applies to millions of people.It regards clinical and methodological dilemmas, but also the matter of vulnerableand fragile time of adolescence and, more generally, children’s rights. Thedecisions need to integrate people’s values and preferences – screening tests needto be acceptable to the population, and treatments need to be acceptable forpatients. Therefore we present one more crucial, but underrepresented in thediscussion, issue of understanding and implementation of the contemporaryprinciples of person-centred care, standards of preventive screening, andguideline development, in the context of screening for scoliosis.

文摘In 2012,China's total grain yield reached 590 million tons and realized nine consecutive years of growth. This is huge historic achievement of China and also rare in development history of world agriculture. However,at the same time of making great achievements,China's agriculture is still confronted with many problems. On the basis of extensive survey,it pointed out 10 outstanding problems: farmland,labor,livestock power,water conservancy,input,agricultural disaster,ecological and environmental problem,waste of resources,economic scale and economic benefits. These problems have brought great adverse influence on China's agricultural development. In view of these problems,to realize sustainable,stable and healthy development of agriculture in the new period,it came up with following recommendations:( i)deepening the understanding;( ii) enforcing laws strictly;( iii) enhancing training;( iv) increasing benefits;( v) saving resources;( vi) protecting environment;( vii) developing science and technology;( viii) consolidating foundation.

文摘The 19th National Congress of the Communist Party of China formulated a major deployment of the rural revitalization strategy from the overall situation of the national cause,and took the rural revitalization strategy as the general gripper of the work of " agriculture,farmers and rural areas". This has important practical significance for realizing agricultural modernization. Through selecting several typical countries,this paper analyzes and introduces the historical experience of rural revitalization. Finally,it comes up with some recommendations and implications.
文摘The betel nut planting area and yield in Hainan have reached 94000 ha and 231000 t,respectively.There are some problems in betel nut planting such as dispersed cultivation,irrational planting layout,excessively dense planting and serious betel nut yellow leaf disease.For the sustainable development of Hainan betel nut,it is necessary to focus on building the disease-resistant betel nut plantation,so as to prevent and control the occurrence and spread of betel nut yellow leaf disease;transform the low-yield betel nut plantation,and strengthen betel nut production management,in order to improve betel nut yield and promote sustainable development of betel nut industry.
文摘BACKGROUND The standard management of autoimmune hepatitis(AIH)is based on corticosteroids,alone or in combination with azathioprine.Second-line treatments are needed for patients who have refractory disease.However,high-quality data on the alternative management of AIH are scarce.AIM To evaluate the efficacy and safety of tacrolimus and mycophenolate mofetil(MMF)and the quality of evidence by using the Grading of Recommendations Assessment,Development and Evaluation approach(GRADE).METHODS A systematic review and meta-analysis of the available data were performed.We calculated pooled event rates for three outcome measures:Biochemical remission,adverse events,and mortality,with their corresponding 95%confidence intervals(CI).RESULTS The pooled biochemical remission rate was 68.9%(95%CI:60.4-76.2)for tacrolimus,and 59.6%(95%CI:54.8-64.2)for MMF,and rates of adverse events were 25.5%(95%CI:12.4-45.3)for tacrolimus and 24.1%(95%CI:15.4-35.7)for MMF.The pooled mortality rate was estimated at 11.5%(95%CI:7.1-18.1)for tacrolimus and 9.01%(95%CI:6.2-12.8)for MMF.Pooled biochemical remission rates for tacrolimus and MMF in patients with intolerance to standard therapy were 56.6%(CI:43.4-56.6)vs 73.5%(CI:58.1-84.7),and among non-responders were 59.1%(CI:48.7-68.8)vs 40.8%(CI:32.3-50.0),respectively.Moreover,the overall quality assessments using GRADE proved to be very low for all our outcomes in both treatment groups.CONCLUSION Tacrolimus and MMF are in practice considered effective for patients with AIH who are non-responders or intolerant to first-line treatment,but we found no high-quality evidence to support this statement.
