Scenario of Infection Prevention and Control Measures for Tuberculosis in Tuberculosis Inpatient and Outpatient Department in Tertiary Care Hospital

Tuberculosis is one of the most important infectious diseases in our country. Also nosocomial infection by tuberculosis can occur, which can be prevented by implementing simple, effective and affordable tuberculosis infection control measures in health care facilities. To evaluate the effectiveness of infection control measures, such study was planned. Questionnaires were administered to all doctors, healthcare workers and servants working in outdoor and indoor department of tuberculosis at tertiary care hospital to assess the knowledge, attitudes and practices on prevention and control of Tuberculosis infection. A scoring system was devised to grade them. One-time audit was also done in outpatient and inpatient department. The analysis showed scoring of poor for doctors, good for nurses and poor forward aids. There is a need to develop strategies for training of health care workers on regular basis in order to reduce the incidence of nosocomial infections. Audit result shows a good level of environmental control measures. Better knowledge, attitude and practices are helpful for the prevention and control of tuberculosis. Also environmental control measures are helpful to prevent infection.

Risk of Active Pulmonary Tuberculosis among Patients with Coal Workers'Pneumoconiosis:A Case-control Study in China

The aim of this study was to estimate the association between occupational, environmental, behavioral risk factors, and active pulmonary tuberculosis（PTB） among coal workers＇ pneumoconiosis（CWP） patients. A matched case-control study was conducted in 86 CWP patients with active PTB and 86 CWP controls without TB. A standardized questionnaire was used for risk factors assessment. Conditioned logistic regression analysis was used to identify associations between the risk factors and active PTB among CWP patients. The results showed that the stage of CWP, poor workplace ventilation, family history of TB, and exposure to TB were independent risk factors for active PTB in patients with CWP with which recommendations for improving work environments, and for case finding activities in patients with CWP could be made.

The strategic framework of tuberculosis control and prevention in the elderly:a scoping review towards End TB targets

With the rapid pace of population ageing,tuberculosis(TB)in the elderly increasingly becomes a public health challenge.Despite the increasing burden and high risks for TB in the elderly,targeted strategy has not been well understood and evaluated.We undertook a scoping review to identify current TB strategies,research and policy gaps in the elderly and summarized the results within a strategic framework towards End TB targets.Databases of Embase,MEDLINE,Global health and EBM reviews were searched for original studies,review articles,and policy papers published in English between January 1990 and December 2015.Articles examining TB strategy,program,guideline or intervention in the elderly from public health perspective were included.Nineteen articles met the inclusion criteria.Most of them were qualitative studies,issued in high-and middle-income countries and after 2000.To break the chain of TB transmission and reactivation in the elderly,infection control,interventions of avoiding delay in diagnosis and containment are essential for preventing transmission,especially in elderly institutions and aged immigrants;screening of latent TB infection and preventive therapy had effective impacts on reducing the risk of reactivation and should be used less reluctantly in older people;optimizing early case-finding with a high index of suspicion,systematic screening for prioritized high-risk groups,initial empirical and adequate follow-up treatment with close monitoring and evaluation,as well as enhanced programmatic management are fundamental pillars for active TB elimination.Evaluation of TB epidemiology,risk factors,impacts and cost-effectiveness of interventions,adopting accurate and rapid diagnostic tools,shorter and less toxic preventive therapy,are critical issues for developing strategy in the elderly towards End TB targets.TB control strategies in the elderly were comprehensively mapped in a causal link pathway.The framework and principals identified in this study will help to evaluate and improve current program,develop targeted strategy,as well as raise more discussions on the research priority settings and policy transitions.Given the scarceness of policy and evaluated interventions,as well as the unawareness of shifting TB epidemiology and strategy especially in developing countries,the increasing need of a ready TB program for the elderly warrants further research.

Identification and attribute analysis of key stakeholders who influence multidrug-resistant tuberculosis prevention and control in China

Background There could be various stakeholders who influencing multidrug-resistant tuberculosis(MDR-TB)policy development and implementation,yet their attributes and roles remain unclear in practice.This study aimed to identify key stakeholders in the process of policy-making for MDR-TB control and prevention and to analyse the attributes and relationships of the stakeholders,providing evidence for further policy research on MDR-TB control.Methods This study was conducted from October 2018 to March 2019 and applied the stakeholder analysis guidelines and domestic stakeholder analysis.An initial candidate stakeholder list was developed by policy scanning.Ten experts were invited to identify these candidate stakeholders.The major attribute of these stakeholders were analysed using the Michell scoring method.Based on these results,the intertwined relationships among groups of stakeholders were analysed and mapped through a systematic scan of the policy and literature on MDR-TB control,as well as information obtained from the interviews.Results A list of 21 types of candidate stakeholders was developed after a literature review and policy scanning,of which 11 received 100%approval.After expert evaluation and identification(the total expert authority was 0.80),19 categories of stakeholders were approved and included in the stakeholder analysis.We categorized all of the stakeholders into three groups:(i)definitive stakeholders who are mainly involved in administrative departments and the Provincial Center for Disease Control and Prevention(CDC);(ii)expectant stakeholders who are mainly involved with MDR-TB patients,clinical departments of TB hospitals at different levels,community health care facilities,prefectural CDC and charity organizations;and(iii)latent stakeholders who mainly involved family members and neighbours of MDR-TB patients and TB related products manufacturers.Government departments and higher-level CDCs have strong decision-making power in developing MDR-TB control policies whereas the recommendations from service providers and the concerns of patients should be considered.Conclusions The MDR-TB prevention system was a multistakeholder cooperation system that was mainly led by government stakeholders.Enhancing communications with front-line service providers and patients on their unmet needs and evidence-based suggestions would highly benefit policy-making of MDR-TB prevention and control.

Tuberculosis infection prevention and control:why we need a whole systems approach

Infection prevention and control(IPC)measures to reduce transmission of drug-resistant and drug-sensitive tuberculosis(TB)in health facilities are well described but poorly implemented.The implementation of TB IPC has been assessed primarily through quantitative and structured approaches that treat administrative,environmental,and personal protective measures as discrete entities.We present an on-going project entitled Umoya omuhle(“good air”),conducted in two provinces of South Africa,that adopts an interdisciplinary,‘whole systems’approach to problem analysis and intervention development for reducing nosocomial transmission of Mycobacterium tuberculosis(Mtb)through improved IPC.We suggest that TB IPC represents a complex intervention that is delivered within a dynamic context shaped by policy guidelines,health facility space,infrastructure,organisation of care,and management culture.Methods drawn from epidemiology,anthropology,and health policy and systems research enable rich contextual analysis of how nosocomial Mtb transmission occurs,as well as opportunities to address the problem holistically.A‘whole systems’approach can identify leverage points within the health facility infrastructure and organisation of care that can inform the design of interventions to reduce the risk of nosocomial Mtb transmission.

The status quo and challenges of prevention and control of chronic obstructive pulmonary disease in China

Introduction Characterized as persistent and progressive pulmonary function declining,chronic obstructive pulmonary disease (COPD) can be accompanied by a systemic inflammatory response.A variety of psychiatric and somatic comorbidities can occur to the patients,such as depression,nutritional disorders,cardiovascular disease,and lung cancer.It is imposing great impacts on the quality of patients' life.In 2010 alone,the economic burden of COPD in the world was as high as 2.1 trillion dollars [1].The high prevalence,mortality,and morbidity have made this disease a major public health problem in socio-economic development with a rapidly aging population in China.

Achievements and challenges of the World Bank Loan/Department for International Development grant-assisted Tuberculosis Control Project in China

In March 2002,the government of China launched the World Bank Loan/ Department for International Development-supported Tuberculosis （TB） Control Project to reduce the prevalence and mortality of TB. The project generated promising results in policy development, strengthening of TB control systems, patient treatment success,funds management, and the introduction of legislation. In light of the global TB epidemic and control environment, it is useful to review the TB control priorities of the project, summarize the achievements and experiences around its implementation.

Efficacy of integrating short-course chemotherapy with Chinese herbs to treat multi-drug resistant pulmonary tuberculosis in China: a study protocol

Background:Tuberculosis(TB)causedMycobacterium tuberculosis(M.tb)is one of infectious disease that lead a large number of morbidity and mortality all over the world.Although no reliable evidence has been found,it is considered that combining chemotherapeutic drugs with Chinese herbs can significantly improves the cure rate and the clinical therapeutic effect.Methods:Multi-drug resistant pulmonary tuberculosis(MDR-PTB,n=258)patients with Qi-yin deficiency syndrome will be randomly assigned into a treatment group(n=172)or control/placebo group(n=86).The treatment group will receive the chemotherapeutic drugs combined with Chinese herbs granules(1+3 granules),while the control group will receive the chemotherapeutic drugs combined with Chinese herbs placebo(1+3 placebo granules).In addition,MDR-PTB(n=312)patients with Yin deficiency lung heat syndrome will be randomly assigned to a treatment(n=208)or control/placebo(n=104)group.The treatment group will receive the chemotherapeutic regimen combined with Chinese herbs granules(2+4 granules),while the control group will receive the chemotherapeutic drugs and Chinese herbs placebo(2+4 placebo granules).The primary outcome is cure rate,the secondary outcomes included time to sputum culture conversion,lesion absorption rate and cavity closure rate.BACTEC^(TM)MGIT^(TM)automated mycobacterial detection system will be used to evaluate theM.tb infection and drug resistance.Chi-square test and Cox regression will be conducted with SAS 9.4 Statistical software to analyze the data.Discussion:The treatment cycle for MDR-PTB using standardized modern medicine could cause lengthy substantial side effects.Chinese herbs have been used for many years to treat MDR-PTB,but are without high-quality evidence.Hence,it is unknown whether Chinese herbs enhances the clinical therapeutic effect of synthetic drugs for treating MDR-PTB.Therefore,this study will be conducted to evaluate the clinical therapeutic effect of combining Chinese herbs and chemotherapeutic drugs to treat MDR-PTB cases.It will assist in screening new therapeutic drugs and establishing treatment plan that aims to improve the clinical therapeutic effect for MDR-PTB patients.Trial registration This trial was registered at ClinicalTrials.gov(ChiCTR1900027720)on 24 November 2019(prospective registered).

Results The focus absorption rate of 87.1%（27/31） in the observation group was better than that （63.6%,14/22） in the control group （P〈0.05）; the rate of bacteria-turned negativity in sputum was 90.5%（19/21）in the observation group which was better than that （56.3%, 9/16） in the control group （P〈0.05）; the observation group in improvement of lassitude, night sweat and cough was superior to the control group （all P〈0.05）. Conclusion Garlic-insulated moxibustion can increase the therapeutic effect for the retreatment patients of pulmonary tuberculosis.

Rising challenge of multidrug-resistant tuberculosis in China:a predictive study using Markov modeling

Background:Multidrug-resistant tuberculosis(MDR-TB)is on the rise in China.This study used a dynamic Markov model to predict the longitudinal trends of MDR-TB in China by 2050 and to assess the effects of alternative control measures.Methods:Eight states of tuberculosis transmission were set up in the Markov model using a hypothetical cohort of 100000 people.The prevalence of MDR-TB and bacteriologically confirmed drug-susceptible tuberculosis(DS-TB+)were simulated and MDR-TB was stratified into whether the disease was treated with the recommended regimen or not.Results:Without any intervention changes to current conditions,the prevalence of DS-TB+was projected to decline 67.7%by 2050,decreasing to 20 per 100000 people,whereas that of MDR-TB was expected to triple to 58/100000.Furthermore,86.2%of the MDR-TB cases would be left untreated by the year of 2050.In the case where MDR-TB detection rate reaches 50%or 70%at 5%per year,the decline in prevalence of MDR-TB would be 25.9 and 36.2%respectively.In the case where treatment coverage was improved to 70%or 100%at 5%per year,MDR-TB prevalence in 2050 would decrease by 13.8 and 24.1%,respectively.If both detection rate and treatment coverage reach 70%,the prevalence of MDR-TB by 2050 would be reduced to 28/100000 by a 51.7%reduction.Conclusions:MDR-TB,especially untreated MDR-TB,would rise rapidly under China’s current MDR-TB control strategies.Interventions designed to promote effective detection and treatment of MDR-TB are imperative in the fights against MDR-TB epidemics.

宏基因组二代测序在实体器官移植感染防控中的应用

器官移植已成为多种终末期疾病的有效治疗手段,但器官移植受者术后需长期服用免疫抑制药,导致免疫功能低下,使得细菌、病毒和真菌感染的发生率相对较高。以病原学培养、免疫学检测和聚合酶链反应为代表的传统微生物检测方法被广泛用于感染检测,但存在耗时长、需预先假定病原体等问题。宏基因组二代测序由于具有病原体检出率高、对病原谱检测全面的优点,近年来被广泛应用于器官移植领域的感染防控。本文就宏基因组二代测序技术在实体器官移植感染防控上的应用现状进行综述,以期对移植相关感染的诊断和治疗提供参考。

猴结核病的流行与防控

非人灵长类(non-human primates,NHPs)是结核病的易感宿主,感染后,结核不仅会在种群中相互传播,也会传播给人类。目前尚无有效的疫苗预防NHPs结核。虽然目前的防控方案已经较为成熟,减少了圈养NHPs结核病的发病率,但疫情仍有发生。本文总结了世界范围圈养和野生环境下猴结核病的流行病学状况,对当前常用检测方法的优缺点进行分析,并总结当前NHPs的防控检测最常见做法。表明结核病对NHPs构成极大威胁,以提高NHPs饲养工作者、管理者对结核病的认知,为完善当前管理程序提供依据,以期为我国猴结核病的诊断防控提供参考。
