Concept of agricultural heritage systems was introduced. As a new heritage type, agricultural heritage systems focus on agricultural systems and its related biodiversity, landscape, land use system, traditional agricultural knowledge and experience, practices, and also the relative cultural diversity which make it the best expression of "agricultural heritage systems are not about the past, it is about the future". Studies about agricultural systems are mainly concentrating on pilot systems, about biodiversity conservation, eco-mechanism and ecological values of the systems, traditional knowledge conservation, community involvement, policies and regulations about the dynamic conservation and adaptive management, and also ways of dynamic conservation and exploration. Being considered as a dynamic approach of protecting agricultural heritage systems, agricultural heritage tourism was compared with rural tourism, agricultural tourism and "farm-stay". Agricultural heritage tourism is actually a type of heritage tourism, and one of its important functions is to build cultural identity of the heritage site and enhance awareness of the local community to conserve their assets. And the studies show that agricultural heritage systems as a kind of tourist resources have great development potentials. 展开更多

AIM: To investigate whether prophylactic abdominal drainage is necessary after pancreatic resection. METHODS: Pub Med, Web of Science, and the Cochrane Library were systematically searched to obtain relevant articles published before January 2014. Publications were retrieved if they met the selection criteria. The outcomes of interest included: mortality, morbidity, postoperative pancreatic fistula(POPF), clinically relevant pancreatic fistula(CRPF), abdominal abscess, reoperation rate, the rate of interventional radiology drainage, and the length of hospital stay. Subgroup analyses were also performed for pancreaticoduodenectomy(PD) and for distal pancreatectomy. Begg's funnel plot and the Egger regression test were employed to assess potential publication bias.RESULTS: Nine eligible studies involving a total of 2794 patients were identified and included in this meta-analysis. Of the included patients, 1373 received prophylactic abdominal drainage. A fixedeffects model meta-analysis showed that placement of prophylactic drainage did not have beneficial effects on clinical outcomes, including morbidity, POPF, CRPF, reoperation, interventional radiology drainage, and length of hospital stay(Ps > 0.05). In addition, prophylactic drainage did not significantly increase the risk of abdominal abscess. Overall analysis showed that omitting prophylactic abdominal drainage resulted in higher mortality after pancreatectomy(OR = 1.56; 95%CI: 0.93-2.92). Subgroup analysis of PD showed similar results to those in the overall analysis. Elimination of prophylactic abdominal drainage after PD led to a significant increase in mortality(OR = 2.39; 95%CI: 1.22-4.69; P = 0.01).CONCLUSION: Prophylactic abdominal drainage after pancreatic resection is still necessary, though more evidence from randomized controlled trials assessing prophylactic drainage after PD and distal pancreatectomy are needed. 展开更多

There is controversy regarding the roles of Ureaplasma urealyticum (U. urealyticum) colo- nization in the development of hronchopulmonary dysplasia (BPD). This study explored the association between U. urealyticum and bronchopulmonary dysplasia at 36 weeks post-menstrual age (BPD36). Studies published before December 31, 2013 were searched from Medline, Embase, Ovid, Web of Sci- ence, and Cochrane databases, with the terms "Ureaplasma urealyticum", "chronic lung disease", or "BPD36" used, and English language as a limit. The association between U. urealyticum colonization and BPD36 was analyzed with RevMan 4.2.10 software, using the odds ratio (OR) and relative risk (RR) for dichotomous variables. Out of the enrolled 81 studies, 11 investigated the BPD36 in total 1193 in- fants. Pooled studies showed no association between U. urealyticum colonization and subsequent de- velopment of BPD36, with the OR and RR being 1.03 (95% CI=0.78-1.37; P=-0.84) and 1.01 (95% CI= 0.88-1.16, P=-0.84), respectively. These findings indicated no association between U. urealyticum colo- nization and the development of BPD36. 展开更多

OBJeCTIve:To systematically evaluate the long-term effect and safety ofXingnao Kaiqiao nee-dling method in ischemic stroke treatment. DATA ReTRIevAL: We retrieved relevant random and semi-random controlled trials that used theXingnao Kaiqiao needling method to treat ischemic stroke compared with various control treatments such as conventional drugs or other acupuncture therapies. Searched databases included China National Knowledge Infrastructure, Weipu Information Resources System, Wanfang Medical Data System, Chinese Biomedical Literature Database, Cochrane Library, and PubMed, from May 2006 to July 2014. SeLeCTION CRITeRIA: Two authors independently conducted literature screening, quality evaluation, and data extraction. The quality of articles was evaluated according to the Cochrane Reviewers’ Handbook 5.1, and the study was carried out using Cochrane system assessment methods. RevMan 5.2 was used for meta-analysis of the included studies. MAIN OUTCOMe MeASUReS: Mortality rate, recurrence rate, and disability rate were observed. ReSULTS:Nine randomized and semi-randomized controlled trials treating 931 cases of ischemic stroke were included in this review. Meta-analysis results showed that there were no sig-niifcant differences in mortality reduction (risk ratio (RR) = 0.58, 95% conifdence interval (CI): 0.17–1.93,Z = 0.89,P = 0.37) or recurrence rate (RR = 0.55, 95%CI: 0.18–1.70,Z = 1.04,P = 0.30) of ischemic stroke patients between theXingnao Kaiqiao needling and control treatment groups. However, theXingnao Kaiqiao needling method had a tendency towards higher efifcacy in mor-tality reduction and recurrence rates. TheXingnao Kaiqiao needling method was signiifcantly better than that of the control treatment in reducing disability rate (RR = 0.51, 95%CI: 0.27–0.98, Z = 2.03,P 〈 0.05). CONCLUSION:TheXingnao Kaiqiao needling method has a better effect than control treatment in reducing disability rate. The long-term effect ofXingnao Kaiqiao needling against ischemic stroke is better than that of control treatment. However, the limitations of this study limit the strength of the conclusions. Randomized controlled trials with a strict, reasonable design, and multi-center, large-scale samples and follow-up are necessary to draw conclusions aboutXingnao Kaiqiao needling. 展开更多

BACKGROUND Vitamin D deficiency is highly prevalent in children with inflammatory bowel disease(IBD). This may contribute to an increased risk of poor bone health and may also influence the course of disease. An optimal treatment strategy of vitamin D therapy in children with IBD has not yet been established.AIM To analyse the published intervention studies of vitamin D therapy in children with IBD.METHODS A systematic review was conducted of clinical studies involving children with IBD(including Crohn disease or ulcerative colitis) who had received vitamin D therapy. Studies up to March 31 st 2018 were identified through MEDLINE,PubMed, EMBASE and the Cochrane Library. Search terms included synonyms of the following terms: vitamin D, paediatric, supplementation, IBD. References of included articles based on abstract were searched for other relevant articles.All relevant articles were accessed and reviewed in full text. Studies fitting the set criteria were included and the remainder were excluded.RESULTS Two hundred and seventy-seven discrete articles were identified. Following assessment of these articles included in the initial search and application of inclusion and exclusion criteria, ten published studies were included in this review. The included studies showed a heterogeneity in study design, inclusion and exclusion criteria, baseline demographics and treatment strategies. Treatment regimens differed in length, supplemented form of vitamin D and factors based upon which dosage was adjusted. Each of the reports included in this review concluded their vitamin D regimens to be safe and well-tolerated. Few of the included studies reported secondary outcomes on the efficacy of vitamin D treatment upon the clinical course of disease or markers of inflammation. Themajority of included trials were not sufficient in raising serum vitamin D levels to an adequate level(30 ng/mL) in children with IBD with vitamin D deficiency.CONCLUSION The included trials featured diverse treatment regimens that were predominantly insufficient in correcting vitamin D deficiency or maintaining adequate levels in children with IBD. Better treatment regimens are required for the management of vitamin D deficiency in children with IBD. 展开更多

A systematic review of the recent literature regarding the current image-guided systems used for cataract surgery or refractive lens exchange was performed based on the PubMed and Google Scholar databases in March 2018. Literature review returned 21 eligible studies. These studies compared image-guided systems with other keratometric devices regarding their accuracy, repeatability and reproducibility in measurement of keratometric values, astigmatism magnitude and axis, as well as in IOL power calculation. Additionally, the image-guided systems were compared with conventional manual ink-marking techniques for the alignment of toric IOLs. In conclusion, image-guided systems seem to be an accurate and reliable technology with measurements of high repeatability and reproducibility regarding the keratometry and IOL power calculation, but not yet interchangeable with the current established and validated keratometric devices. However, they are superior over the conventional manual inkmarking techniques for toric IOL alignment. 展开更多

This paper reviews the current literature on the relationship between air pollution and food security from the perspective of food system. It highlights that agricultural emissions which substantially contribute to air pollution could happen at every stage along the food supply chain. Meanwhile, air pollution can not only affect plant growth and animal health but also shift market equilibrium of both agro-inputs and outputs in the food supply chain and thereby affect food security indirectly. Furthermore, this study evaluates the effects of agricultural policy and energy policy on food security and air pollution, respectively, and provides an overview of potential policy instruments to reduce air pollution while ensuring food security. Finally, we identify the remaining research and policy issues for further studies, mainly focusing on the study of household's bounded rational behaviors and the issue of rural aging population. 展开更多

The objectives of this article are as follows: 1) to propose a university research ethics system framework, 2) to provide a brief anatomy of the Meru University of Science and Technology (MUST) Institutional Research Ethics Review Committee (MIRERC), 3) to perform a SWOT (Strengths, Weaknesses, Opportunities, and Threats) analysis of MIRERC, and 4) to make recommendations for improving its performance. The 13-member multi-disciplinary MIRERC was established in April 2017 to provide effective ethical oversight of research undertaken by the University’s scholarly community. Strengths of the MUST research ethics review system include a functional MIRERC, a pertinent national law and ethical guidelines, an Innovation and Enterprise Centre that could house a dedicated MIRERC Secretariat, and a supportive University Management Board. The weaknesses include lack of graduate schools to assure scientific rigor of proposals before submission to the MIRERC, lack of research ethics training in most school’s curricula, absence of a dedicated MIRERC Secretariat, undergraduate research proposals being not ethically reviewed, dearth of faculty trained in research ethics, and lack of an operating budget for MIRERC work. The opportunities include existence of about 22 accredited Institutional Research Ethics Review Committees (IRERC) in Kenya, existence of international standards and operational guidance for ethics review, availability of guidelines and codes of best ethical practices in research, existence of a free automated platform called Research for Health Innovation Organizer (RHInnO) Ethics for managing the ethics review process, and availability of external resources for strengthening IRERCs. In order to improve the performance and sustainability of the MUST research ethics system, there is need to include research ethics training in all undergraduate and post-graduate curricula, create a dynamic database of potential research ethics reviewers, allocate a percentage of the annual MUST research budget for MIRERC operations, charge a graduated fee for proposal ethics review, require all students’ and faculties’ internal and external research proposals be cleared by the MIRERC, and use the RHInnO Ethics platform to manage the ethics review process. 展开更多

A photovoltaic (PV) string with multiple modules with bypass diodes frequently deployed on a variety of autonomous PV systems may present multiple power peaks under uneven shading. For optimal solar harvesting, there is a need for a control schema to force the PV string to operate at global maximum power point (GMPP). While a lot of tracking methods have been proposed in the literature, they are usually complex and do not fully take advantage of the available characteristics of the PV array. This work highlights how the voltage at operating point and the forward voltage of the bypass diode are considered to design a global maximum power point tracking (GMPPT) algorithm with a very limited global search phase called Fast GMPPT. This algorithm successfully tracks GMPP between 94% and 98% of the time under a theoretical evaluation. It is then compared against Perturb and Observe, Deterministic Particle Swarm Optimization, and Grey Wolf Optimization under a sequence of irradiance steps as well as a power-over-voltage characteristics profile that mimics the electrical characteristics of a PV string under varying partial shading conditions. Overall, the simulation with the sequence of irradiance steps shows that while Fast GMPPT does not have the best convergence time, it has an excellent convergence rate as well as causes the least amount of power loss during the global search phase. Experimental test under varying partial shading conditions shows that while the GMPPT proposal is simple and lightweight, it is very performant under a wide range of dynamically varying partial shading conditions and boasts the best energy efficiency (94.74%) out of the 4 tested algorithms. 展开更多

Background and Purpose: Therapeutic communication is a new term in family health care nursing, defined by Hohashi (2019) as a method of family intervention, and characterized by inclusion of not only verbal conversation but also nonverbal interaction. However, specific therapeutic communication methods have not been systematized. The purpose of this study was to clarify therapeutic communication methods for families/family members from the perspectives of verbal communication and non-verbal communication through a review of existing literature. Methods: We conducted a search using the medical literature databases PubMed and Ichushi-Web using the keywords “therapeutic communication”. Analysis was performed on seven articles from PubMed and 14 articles from Ichushi-Web that described therapeutic communication methods performed by healthcare professionals for families/family members. Through directed content analysis, therapeutic communication methods were subcategorized, and classified into three categories: verbal communication, non-verbal communication, and verbal/non-verbal communication. Results: A total of 23 subcategories were extracted. Verbal communication included 11 subcategories, such as “asking questions using the communicatee’s words as they are”. Non-verbal communication included five subcategories, such as “noticing changes in the content of the communicatee’s story”. And verbal/non-verbal communication featured seven subcategories, such as “making the communicatee aware of one’s own beliefs”. Conclusion: Therapeutic communication methods included basic care/caring in family interviews/meetings, as well as verbal communication and non-verbal communication that act on family/family members’ beliefs. It is believed that changes in family/family members’ beliefs can be used to eliminate, reduce, or improve problematic conditions in the family. . 展开更多

China was one of the earliest countries to set up a system to continuously inventory natural forest resources. From the beginning of the 1970s until today, seven forest resource inventories have been carried out. This research summarizes the progress of forest continuous inventories and analyzes the existing deficiencies ofChina’s forest continuous inventory system and forest management plan inventory. As stated above, this research offers corresponding countermeasures and suggestions: establishing a sample plot system for comprehensive national forest inventory and monitoring with each province’s continuous forest inventory based on the foundation of the national sample plot system, able to develop the province as a subset of the overall province-level forest resource inventory according to the actual conditions in each province. Through annual multi-resource/multi-benefit surveying of the forests, the monitoring of forest amounts, quality, functions and benefits will be assisted in its entirety. The further integration of the forest continuous inventory and the forest management plan inventory is also discussed. This research also proposes the varied probability sampling method with sub-compartments as the basic sampling unit (or combinations of sub-compartments). This will also satisfy the requirements of ecological inventory by region. 展开更多
