Intestinal complications in patients with Crohn's disease in the Brazilian public healthcare system between 2011 and 2020

BACKGROUND This is a secondary database study using the Brazilian public healthcare system database.AIM To describe intestinal complications(ICs)of patients in the Brazilian public healthcare system with Crohn’s disease(CD)who initiated and either only received conventional therapy(CVT)or also initiated anti-tumor necrosis factor(anti-TNF)therapy between 2011 and 2020.METHODS This study included patients with CD[international classification of diseases–10th revision(ICD-10):K50.0,K50.1,or K50.8](age:≥18 years)with at least one claim of CVT(sulfasalazine,azathioprine,mesalazine,or methotrexate).IC was defined as a CD-related hospitalization,pre-defined procedure codes(from rectum or intestinal surgery groups),and/or associated disease(pre-defined ICD-10 codes),and overall(one or more type of ICs).RESULTS In the 16809 patients with CD that met the inclusion criteria,the mean follow-up duration was 4.44(2.37)years.In total,14697 claims of ICs were found from 4633 patients.Over the 1-and 5-year of follow-up,8.3%and 8.2%of the patients with CD,respectively,presented at least one IC,of which fistula(31%)and fistulotomy(48%)were the most commonly reported.The overall incidence rate(95%CI)of ICs was 6.8(6.5–7.04)per 100 patient years for patients using only-CVT,and 9.2(8.8–9.6)for patients with evidence of anti-TNF therapy.CONCLUSION The outcomes highlighted an important and constant rate of ICs over time in all the CD populations assessed,especially in patients exposed to anti-TNF therapy.This outcome revealed insights into the real-world treatment and complications relevant to patients with CD and highlights that this disease remains a concern that may require additional treatment strategies in the Brazilian public healthcare system.

Reacting to Epidemics:The Innovative Imperial Public Health System during the Late Northern Song Dynasty

Song China was a period in which China experienced a great increase in its population.Concurrently,the Song dynasty also experienced a rise in the frequency of epidemics and two major wars with the Western Xia and Liao dynasties during the 1000s and 1040s.The consequences of these changes were exacerbated by the increased geographical mobility of certain social groups such as traders and examinees attending civil service examinations.Thus,casualties of wars,epidemics,or disease,especially of people whose families were far away and could not care for them were left without care and“their corpses often lay bare along the roads.”This new social environment created a need for general relief.The Northern Song government(960-1127 CE),especially during the reign of Emperor Huizong,established an innovative public health system to address this issue.The public health system included poorhouses,public hospitals,and pauper’s cemeteries.The first were more of charity organizations,whereas the latter two promoted public health by providing medical services for the poor and burial for those that nobody cared for.In terms of rationale behind these institutions,on the one hand,they constituted an attempt to get the poor and homeless off the streets while providing them relief or burial.On the other hand,it seems that Huizong’s deep concern with medicine propelled him to design and implement a comprehensive public health system oriented to prevent contagion and outbreak of epidemics.This article depicts the background,the organization,and the functions of the system.The article also discusses the conditions and reasons that gave rise to such a unique undertaking by the Northern Song government.

The Supply-Demand Analysis and Mechanism Innovation of Chinese Rural Public Goods

The connotation of rural public goods is expounded.The rural public goods refer to the products and labors that satisfy the production and living of rural residents,economic growth and social progress.The rural public goods is characterized by non-excludability,non-competitiveness and indispensability of other general public goods.The supply situation of Chinese government to rural public goods is analyzed,as well as the demand situation of rural public goods,which includes farmers' demand on training,the assistance demand of rural weak groups,farmers' demand on comfortable living conditions and farmers' demand on "soft" public goods.The paths for innovating the supply mechanism of rural public goods are put forward,which cover perfecting the decision mechanism of public goods supply;scientifically distributing the supply responsibility of rural public goods;facilitating the reform of each supporting equipment and exploring the multiple capital collecting channels of rural public goods.

Demand of Rural Public Goods in Western Ethnic Minority Areas

In the context of Development of the West Regions and the construction of new countryside,on the basis of defining the concept of public goods,this article analyzes the status quo and layers of demand of rural public goods in western ethnic minority areas:the demand of rural public goods in ethnic minority areas shows "pyramid" structure,that is,the most basic layer is production-based rural public goods,followed by life-based rural public goods and democratic-management-based rural public goods.Finally the countermeasures for achieving effective demand of rural public goods are put forward as follows:adhere to customers(farmers)-oriented principle;innovate upon the rural residents' demand expression mechanism of public goods in ethnic minority areas;achieve diversification of supply subject of rural public goods in ethnic minority areas.

Creating Inclusive Global Value Chains under the BRI from the Perspective of Public Goods Supply and Demand

Supply and demand of public goods provide a brand-new theoretical framework for research on the creation of inclusive global value chains(GVCs)under the Belt and Road Initiative(BRI).The supply of international public goods is an important positive variable for creating global value chains under the BRI,in which China and other developing countries involved,as well as their small and medium-sized enterprises(SMEs),are microscopic entities.When the BRI’s supply of instrumental,institutional,and conceptual international public goods is in equilibrium with the demand of GVC entities for public goods,the BRI creates necessary conditions for the extension of GVCs.GVCs created under the BRI are of great value in promoting inclusiveness,fair income distribution,balanced regional development,and the restructuring of international economic governance.Under the current GVC system,some developed countries have been wary about the BRI and even developed misgivings and biases.Nevertheless,developed countries may play an active role in bridging gaps in the BRI’s development and complement their respective strengths with developing countries for win-win cooperation.

Soft Computing of Biochemical Oxygen Demand Using an Improved T–S Fuzzy Neural Network

It is difficult to measure the online values of biochemical oxygen demand(BOD) due to the characteristics of nonlinear dynamics, large lag and uncertainty in wastewater treatment process. In this paper, based on the knowledge representation ability and learning capability, an improved T–S fuzzy neural network(TSFNN) is introduced to predict BOD values by the soft computing method. In this improved TSFNN, a K-means clustering is used to initialize the structure of TSFNN, including the number of fuzzy rules and parameters of membership function. For training TSFNN, a gradient descent method with the momentum item is used to adjust antecedent parameters and consequent parameters. This improved TSFNN is applied to predict the BOD values in effluent of the wastewater treatment process. The simulation results show that the TSFNN with K-means clustering algorithm can measure the BOD values accurately. The algorithm presents better approximation performance than some other methods.

Performance Evaluation of Public Bus Transportation by Using DEA Models and Shannon’s Entropy:An Example From a Company in a Large City of China

The purpose of this paper is to assess the operational efficiency of a public bus transportation via a case study from a company in a large city of China by using data envelopment analysis(DEA)model and Shannon’s entropy.This company operates 37 main routes on the backbone roads.Thus,it plays a significant role in public transportation in the city.According to bus industry norms,an efficiency evaluation index system is constructed from the perspective of both company operations and passenger demands.For passenger satisfaction,passenger waiting time and passenger-crowding degree are considered,and they are undesirable indicators.To describe such indicators,a superefficient DEA model is constructed.With this model,by using actual data,efficiency is evaluated for each bus route.Results show that the DEA model with Shannon’s entropy being combined achieves more reasonable results.Also,sensitivity analysis is presented.Therefore,the results are meaningful for the company to improve its operations and management.

Cotton's Water Demand and Water-Saving Benefits under Drip Irrigation with Plastic Film Mulch

The primary purpose of this research was to give suitable irrigation program according to the growth period and water requirement.A cotton field experiment with mulched drip irrigation was conducted at the National Field Observation and Research Station for Oasis Farmland Ecosystem in Aksu of Xinjiang in 2008.Water balance method was adopted to study the water requirement and water consumption law of cotton under mulched drip irrigation in Tarim Irrigated Area.Statistical analysis of experimental data of irrigation indicates that the relationship between yield of cotton and irrigation presents a quadratic parabola.We fit the model of cotton water production on the basis of field experimental data of cotton.And the analysis on water saving benefit of cotton under mulched drip irrigation was done.Results indicate that water requirements for the irrigated cotton are 543 mm in Tarim Irrigated Area.The water requirements of seedling stage is 252 mm,budding stage is 186 mm,bolling stage is 316 mm and wadding stage is 139 mm.the irrigation amount determines the spatial distribution of soil moisture and water consumption during cotton life cycle.However,water consumption at different growth stages was inconsistent with irrigation.Quantitatively,the water consumed by cotton decreases upon the increase of irrigation amount.From the perspective of water saving,the maximal water use efficiency can reach 3 091 m3/ha.But the highest cotton yield needs 3464 m3/ha irrigation water.In summary,compared to the conventional drip irrigation,a number of benefits in water saving and yield increase were observed when using plastic mulch.At the same amount of irrigation,the cotton yield with plastic mulch was 30.2% higher than conventional approaches,and the efficiency of water utilization increased by30.2%.While at the same yield level,29.3% water was saved by using plastic mulch,and the efficiency increased by 41.5%.

On the Plaintiff's Subject Qualification for Environmental Public Interest Litigation Instituted by People's Procuratorates

Although it is not the main duty for the People's Procuratorate to institute environmental public interest litigation proceedings, the existence of "reserve" prosecution right of plaintiff not only is beneficial to timely prevention and cure of environmental damage, but also contributes indispensable judicial supervision force to the environmental legality construction. In order to safeguard environmental public interests, many local prosecutorial organizations have practiced environmental public interests litigation. Since Chinese law has not made explicit stipulation on the function of the People's Procuratorate instituting environmental public interest litigation, the plaintiff's subject qualification for environmental public interest litigation instituted by the People's Procuratorate is still in question. In order to propel the People's Procuratorate to completely and fully exercise their power of supervision and prosecution, there shall be corresponding legislation that provides powerful guarantee for the People's Procuratorate instituting environmental public interest litigation.
