Singapore Neurologic Infections Program
Central Nervous System InfectionsWorldwide, central nervous system infections such as inflammation of brain (encephalitis), inflammation of meninges (meningitis) and sudden onset of weakness of muscles which maybe infectious in origin result in significant illness and death and healthcare costs. Vast majority of central nervous system infections remain without an identifiable cause. There is also concern about new and emerging infections. This study thus intends to fill in the gaps in knowledge with regards to central nervous system infections in Singapore to give a thorough description of burden of causes of central nervous system infections and detection of outbreaks of new pathogens. Patients suspected of central nervous system infection will be recruited from 5 restructured Singapore hospitals and their blood and other clinical specimens will be sent for testing. Patients will also be followed up to assess long term outcomes and socio-economic costs of these infections. This will help clinicians, policymakers and public health officials in estimating financial and societal costs of CNs infections in Singapore.
Infection Surveillance in Intensive Care Patients
InfectionPneumonia2 morePurpose of the study is to investigate and quantify known and possible new riskfactors for nosocomiel infection and death in the intensive care setting. As new riskfactors Mannose Binding Lechtin and Procalcitonin are chosen and compared to established riskfactors.

To study the specific pathogens on 100 cases of unexplained death due to infectious diseases in the files of Taiwan CDC and the Forensic Institutes of Department of Law and Justice. To study the distribution of children lymphoid lesions in Vietnam and Taiwan and their virus association. To establish a tissue bank for infectious diseases and lymphoma.
Study of the Role of Dendritic Cells in the Recurrence of Hepatitis C After Liver Transplantation....
HCV InfectionRe-infection of the liver graft occurs universally following liver transplantation for HCV-induced end stage liver disease. Interestingly, the manifestation of HCV infection ranging from an asymptomatic carrier state to rapid progression to liver cirrhosis is extremely variable from one patient to another. The host and viral factors being responsible for the different course of HCV infection are poorly understood. Our study will focus on dendritic cells which are known to play a critical role in the control of viral infection. Viral factors (quasispecies evolution) will also be analysed and Th1 Th2 cytokines produced in the serum evaluated.Thirty liver transplanted patients will be included : 20 patients transplanted for HCV-related disease and 10 controls transplanted for non HCV-related disease. Blood samples will be taken just before transplantation and at different time -points up to 5 years after transplantation. Function of blood monocyte-derived DC will be evaluated. Circulating blood plasmacytoid (pDC) and myeloid DC (mDC) sub-populations will be enumerated. HCV quasispecies evolution will be analysed. This study may help to define prognostic markers on progression of hepatitis C in liver transplantation and allow the development of new immunotherapeutic drugs
Evaluate Three Methods for Diagnosis of Invasive Fungal Infection in Chinese Patients After HSCT...
Invasive Fungal InfectionAspergillosis2 moreThe purpose of this study is to assess the cut-off value of GM/G test in Chinese patients after hematopoietic stem cell transplantation, and evaluate GM/G test and real-time PCR for diagnosis of IFI in Chinese patients.
Long Term Outcomes of EV71 CNS Infection
Central Nervous System InfectionOur study involved 142 children with EV71 CNS infections that included 61 (43%) with viral meningitis, 53 (37%) with severe CNS involvement including encephalitis, polio-like syndrome and encephalomyelitis, and 28 (20%) with cardiopulmonary failure after CNS involvement. These children were subjected to physical and neurological examinations 2.85 (range 1.0-7.39) years after disease onset. Those below the age of 6 years took the Denver developmental screening test, while those 4 years and over took the intelligence quotient (IQ) test.
Selective Reporting of Antibiotic Susceptibility Test Results in Urinary Tract Infections in the...
Urinary Tract InfectionsAntibiotic resistance is a serious and increasing worldwide threat to global public health. One of antibiotic stewardship programmes' objectives is to reduce inappropriate broad-spectrum antibiotics' prescription. Selective reporting of antibiotic susceptibility test (AST) results, which consists of reporting to prescribers only few (n=5-6) antibiotics, preferring first-line and narrow-spectrum agents, is one possible strategy advised in recommendations. However, selective reporting of AST has never been evaluated using an experimental design. This study is a pragmatic, prospective, multicentre, controlled (selective reporting vs usual complete reporting of AST), before-after (year 2019 vs 2017) study. Selective reporting of AST is scheduled to be implemented from September 2018 in the ATOUTBIO group of 21 laboratories for all E. coli identified in urine cultures in adult outpatients, and to be compared to the usual complete AST performed in the EVOLAB group of 20 laboratories. The main objective is to assess the impact of selective reporting of AST for E. coli positive urine cultures in the outpatient setting on the prescription of broad-spectrum antibiotics frequently used for urinary tract infections (amoxicillin-clavulanate, third generation cephalosporins and fluoroquinolones). The primary endpoint is the after (2019) - before (2017) difference in prescription rates for the previously mentioned antibiotics/classes that will be compared between the two laboratory groups, using linear regression models. Secondary objectives are to evaluate the feasibility of selective reporting of AST implementation by French laboratories and their acceptability by organising focus groups and individual semi-structured interviews with general practitioners and laboratory professionals.
Study on Appropriate Technology of Standardized Diagnosis and Treatment for Diabetic Patients With...
Diabetes MellitusPulmonary InfectionFocusing on patients with diabetes complicated with pulmonary infection, the purpose of this study is: 1) to identify the epidemiology, etiologic spectrum and status of diagnosis and treatment; 2) to develop a symptom score scale , clarify the risk factors and create a precise warning model; 3) to develop a rapid detection of pathogen of lower respiratory infection, to establish clinical pathways of early diagnosis and treatment of diabetes complicated with pulmonary infections (including bacterial, tuberculosis and fungal infections) and then make an application in clinic.

Intraoperative Hyperglycemia and Infections After Orthopedic Surgery
Severe HyperglycemiaPostoperative Infection1 morePostoperative infections are a common complication. A relationship between perioperative severe hyperglycemia and postoperative infections has been found in patients undergoing craniotomy. The aim of this study is to evaluate the epidemiology of intraoperative severe hyperglycemia (BGC >180 mg/dL; 10 mmol/L) and postoperative infections (wound, urinary and prosthetic joint infection) and to investigate if severe intraoperative hyperglycemia is associated with an higher risk of early postoperative (within the 7th postoperative days) infections (wound, urinary and prosthetic joint infection).
