A Survey Towards Holistic Management of Schizophrenia

Holistic management of schizophrenia involves main stream pharmacological intervention,complimentary medicine intervention,therapeutic intervention,and other psychosocial factors,such as accommodation,education,job training,employment,relationship,friendship,exercise,overall well-being,smoking,substance abuse,suicide prevention,stigmatisation,recreation,entertainment,violent behaviour,arrangement of public trusteeship and guardianship,day-day-living skill,integration with community,management of overweight due to medications,and other health complications related to medications amongst others.Our review shows that there is no integrated survey by combining all these factors.We are conducting an international web based survey to evaluate the significance of all these factors and present them in a unified manner.We believe this investigation will contribute positively towards holistic management of schizophrenia.There will be two surveys.In the pharmacological intervention survey,five popular drugs for schizophrenia will be chosen and their efficacy as well as harmful side effects will be evaluated in a scale of 0-10.This survey will be done by psychiatrists.In the second survey,each element of therapeutic intervention and psychosocial factors will be evaluated according to their significance in a scale of 0-10.This survey will be done by care givers,psychologists,case managers,and case workers.For the first survey,we will contact the professional bodies of the psychiatrists in English speaking countries and request them to ask their members to participate in the survey.For the second survey,we will contact the professional bodies of clinical psychologist and care givers in English speaking countries and request them to ask their members to participate in the survey.Additionally for both the surveys,we will contact the relevant professionals through personal contact networks.For both the surveys,mean,mode,median,standard deviation,and net promoter score will be calculated for each factor and presented then in a statistically significant manner.Subsequently,each factor will be ranked according to their statistical significance.Additionally,country specific variation will be highlighted to identify the variation pattern.The results of these surveys will identify the relative significance of each type of pharmacological intervention,each type of therapeutic intervention,and each type of psychosocial factor.The determination of this relative importance will definitely contribute to the improvement in quality of life for individuals with schizophrenia.

Management of AE-CB/COPD: a Survey of Respiratory Physicians in Some Regions of China

Objective To investigate the bacteria spectrum isolated from AE-CB/COPD and the manner of management of AE-CB/COPD in respiratory or internal medicine department in some regions of China. Methods Respiratory physicians received questionnaire at randomization just after they managed a patient presenting to outpatient department with AE-CB/COPD, on general conditions and symptoms of patients, type of examinations, diagnosis, type of antibiotics used and mode of administration. Results of sputum bacteria culture were followed up. Results Among the 1583 AE-CB/COPD, 63.04% were male and 35.19% were female. 54.6% of them were older than 60 years. 81.87% of the patients produced sputum. Sputum bacteria culture, chest X-ray and chest CT were carried out to 21.3%, 66.3% and 11.1% patients, respectively. 355 strains were isolated from patients whose sputum bacteria culture was positive. Streptococcus pneumoniae, Haemophilus influenzae and Moraxella catarrhalis were the three most isolates. 84.7% of the 1583 AE-CB/COPD received 1692 times of antibiotic prescribing. The most frequently prescribed antibiotic were B-lactams (51.36% of all antibiotic prescribing), macrolides (14.01%) and quinolones (31.03%). Much more macrolides were prescribed in the area where more patients pay the medicines at his own expense than those in the area where more patients share public health service. Conclusion In China, respiratory physicians can reasonably select antibiotics to manage acute exacerbation of chronic bronchitis/ chronic obstructive pulmonary disease in pulmonary outpatient department. Sputum culture is done in part of the patients, but susceptibility tests are missing. One issue revealed by the survey is that the list of prescribing medications laid down by government have great influence on antibiotic use.

A Survey of Hatchery Waste Management Practices

A survey of major chicken meat hatcheries in Australia was undertaken in 2008 to identify how hatchery waste is currently managed. A weekly average of 10.4 tonnes of waste is produced by chicken meat hatcheries. The cost of disposal （average $127/tonne） and availability of disposal sites is an emerging issue. The majority of hatchery waste is sent to land fill or for composting, with some rendered for use as pet food. Hatchery wastewater is mostly used for irrigation or disposed directly into the sewer. Most of the hatcheries have no environmental issues with hatchery waste on site but some report odour problems. Some hatcheries would like to treat the waste on site so that it could be sold as a commodity or to use methods to separate liquid from solid waste and recycle water.

Survey of the management of borderline ovarian tumors in the United Kingdom

Borderline ovarian tumors （BOTs） represent approxi-mately 10% of ovarian neoplasms and are a heteroge-neous group of tumors with variable biological behav-iour. The majority present with disease confned to the ovary and have an excellent prognosis after surgical removal. A small proportion subsequently has recur-rent disease or progression to invasive cancer. Tumor recurrence can occur up to 20 years after surgical resection. There are no robust clinical, histological or molecular markers that distinguish high risk cases and no satisfactory treatment for patients with progressive disease. This results in great variability in management in different centres. We conducted a national survey on the management of borderline ovarian tumors in cancer centres representing different regions in the United Kingdom. In this article we review the literature for the current concepts in diagnosis, treatment and follow up of BOTs and we report the results of the survey of current practice in the United Kingdom. On that basis we provide recommendations for the management of patients with BOTs.

A Survey of Current Treatment Practices for Postpartum Hemorrhage by Practicing Obstetricians and Hematologists

Objective: To identify current treatment strategies for postpartum hemorrhage used by obstetricians (OB/GYNs) and hematologists (HEMs). Study Design: We conducted a survey of OB/GYNs (n = 220) and HEMs (n = 30) to describe the characteristics of current treatment strategies for postpartum hemorrhage. Surveys were administered via a structured questionnaire on a secure internet website from 5 - 12 October 2009. Results: The majority of OB/GYN and HEM respondents were practicing in a community hospital environment (77%). Of the OB/GYNs, the majority practiced at hospitals with over 2000 deliveries per year (77%). A majority (58%) of OB/GYNs were affiliated with hospitals that lacked a massive transfusion protocol to treat severe postpartum hemorrhage. Subsequent to uterine massage and additional oxytocin, the majority of OB/GYNs (73%), preferred the administration of Methergine? as the next level of intervention for postpartum hemorrhage. There was considerable variability in response to specific treatment strategies for several hypothetical case scenarios;however, the large majority of OB/GYNs favored obstetrical procedures over interventional radiology or administration of rFVIIa. A large majority (77%) of physicians who are familiar with rRVIIa as treatment for postpartum hemorrhage reported being very satisfied with the agent for this indication. Conclusions: An established, systematic treatment strategy among OB/GYNs emerged only in the case of mild postpartum hemorrhage.

Alternative fuels—a new field for mine surveying

Due to the public’s increased interest in renewable energies and the “Erneuerbare Energien Gesetz” (EEG) from February 2000, geothermal energy and other alternative or renewable energies gain more and more importance. As far as Germany is concerned, geothermal energy and coal bed/mine methane are considered as mineral resources according to the German mining law. This demands the participation of mine surveyors/mineral resources managers from the planning to the production stage and even beyond it. The main tasks that have to be fulfilled are, among others, applications for exploration and production licences as well as the evaluation of the resource’s potential. This paper indicates the tasks of mine surveyors/mineral resources managers in the wide area of the renewable energies in Germany, especially concerning the use of geothermal energy and methane.

The US Payor Landscape： Results from a Survey of Medical Directors and Pharmacy Directors on Comparative-Effectiveness Research

The paper is to determine the types of approaches preferred by medical and pharmacy directors of US payer organizations to enhance the Pharmacy ＆ Therapeutic decision-making process and how medications accepted onto the formulary should be covered. An online interactive survey of US medical and pharmacy directors was conducted in 2012. In addition to a 10-point Likert scale （10 = agree completely, 1 = disagree completely）, qualitative responses and interpretive analysis were used to explore beliefs about certain statements. The results showed that the 30 respondents （20 medical directors and 10 pharmacy directors） rated current progress in obtaining usable CER （comparative-effectiveness research） at only an average of 4.17 on the 10-point scale. They hoped to regularly utilize CER information in formulary decision making by 2015 （average rating, 6.03）. The rating of evidence-based medicine use in coverage decision making today was somewhat higher, at an average of 7.08 （medical directors, 7.38; pharmacy directors, 6.40）. The survey participants believe that emerging CER results will greatly affect the following areas： optimization/improvement of clinical guidelines, medical/pharmacy benefit management, assessments of the value and appropriateness of interventions, and pharmaceutical research and development. Therefore, payers expect CER to play an increasing role in helping them determine the value of new therapies.

This paper concentrates on residents’ satisfaction of water environment management in Jinan section of Xiaoqing River, using questionnaires to find out the problems and effects of Xiaoqing River management. Based on the correlation analysis of the questionnaire data, the results show that five factors including the impact of water pollution, understanding of Xiaoqing River governance, willingness to participate in Xiaoqing River governance, policy publicity, and government regulation have a positive impact on the satisfaction of Xiaoqing River water environment governance. Finally, the paper puts forward some countermeasures and suggestions to increase residents’ satisfaction from five aspects, such as increasing publicity efforts, paying attention to the cultivation of public participation consciousness, etc.

Is tuberculosis patients management improved in the integrated TB control model in West China?A survey in Guizhou Province,China

Background:Tuberculosis(TB)patient management(TPM)is crucial to improve patient compliance to treatment.The coverage of TPM delivered by TB dispensaries or Centers for Disease Control and Prevention(CDC)was not high under the previous CDC model of TB control in China.In the integrated TB control model in China,TB patient management(TPM)was mainly delivered by lay health workers(LHWs)in primary health care(PHC)sectors.This study aims to investigate TPM delivery in resource-limited western China and to identify factors affecting TPM delivery by LHWs under the integrated TB control model.Methods:A stratified random sampling was used to select study sites.Pulmonary TB(PTB)patients≥15 years old from selected counties/districts in Guizhou Province were surveyed from August 2015 to May 2016.Structured questionnaires were used to collect data.Aχ^2 test and logistic regression were used to identify factors associated with self-administered treatment(non-TPM).Results:In total,638 PTB patients were included in the final analysis.Close to 30%of patients were ethnic minorities.More than 30%of patients were from counties with high TB burden,and 24.9%of patients had poor compliance to treatment.Only 37.1%of patients received TPM delivered by LHWs under the integrated TB control model throughout the treatment period.The main reasons for unwillingness to manage reported by patients included social stigma and no perceived need.Being ethnic minorities(OR=3.35)was a main factor associated with lower likelihood of receiving TPM,while living in areas with middle or high TB burden may increase the likelihood of receiving TPM(OR=0.17 and 0.25,respectively).Among current management approaches,more than 85%of patients chose phone reminder as their preferred TPM by LHWs.Conclusions:TPM under the integrated model in West China is still low and need further improvement,and the impeding factors of TPM need to be addressed.Strengthening patient-centered and community-based TPM and developing more feasible approaches of TPM delivery should be explored in future research in this region.

商业银行设立理财子公司能够实现风险隔离吗?

本文以中国商业银行设立理财子公司为准自然实验,基于2018—2021年84家银行的季度财务数据,采用渐进双重差分模型(DID)考察商业银行设立理财子公司的风险隔离效应。研究发现:设立理财子公司显著降低了母公司商业银行的风险承担,能够实现理财业务与其他业务的风险隔离,且设立时间越长,风险隔离效应越显著。异质性检验和机制分析表明,这种风险隔离效应在城商行与农商行中最弱;“去嵌套、降杠杆”和“去池化、缓错配”是实现风险隔离的主要机制。对母公司商业银行和理财子公司并表的进一步分析发现,设立理财子公司不能降低银行控股集团的整体风险承担,仅能实现风险隔离。这些研究发现对于完善商业银行内部控制和外部监管具有重要启示。
