Filter by:In order to assess the burden of respiratory syncytial virus on infant mortality in Pakistan, nasopharyngeal swab sampling and minimally invasive tissue sampling (MITS) will be conducted on deceased infants under 6 months of age. The specimens will be analysed by the microbiology and histopathology labs at Aga Khan University, Karachi, Pakistan. Verbal consent will be obtained from parents of deceased infants, and a cause of death lab report and grief counseling services will be offered to enrolled parents who gave consent for specimen collection. The study is funded by Bill & Melinda Gates Foundation in affiliation with Research Triangle Institute (RTI) MITS Surveillance Alliance.
This is an observational study to evaluate the utility of the latest recommendation to define severity of infection for sepsis patients (sepsis-3), and to identify the aetiology and factors associated with outcome of community-acquired sepsis in Northeast Thailand. Potential study participants will be adult patients who are presented at the hospital with community-acquired sepsis. Clinical specimens (including blood, urine, sputum, throat swabs and pus or wound swab) will be collected from each participant on admission for culture, PCR and serological tests, and other laboratory tests. Participants' treatment will be closely monitored during the duration of their hospital stay. Blood will be again collected at 72 hours after admission. Participants will be contacted at 28 days after admission to determine clinical outcome by phone interview with standardized script.
Community-acquired pneumonia (CAP) is a heterogeneous disease causing great morbidity, mortality and health care burden globally. Typing methods for discriminating different clinical conditions of the same disease are essential to a better management of CAP. Traditional typing systems based separately on clinical manifestations (such as PSI and CURB-65), pathogens(bacterial types, virulence, drug resistance, etc) or host immune state (immunocompetent, immunocompromised or immunodeficiency). Thus, they are barely able to represent the real disease status nor to precisely predict the mortality. As the development of multi-omic technologies, the relatedness of different phenotypes at a molecular level have revolutionized our ability to differentiate among patients. Our study is aimed at establishing a novel molecular typing method of CAP. Multi-omic (including genomics, transcriptomes, and metabolisms) data obtained from enrolled CAP patients and isolated pathogens would be integrated analyzed and interpreted. Tthe investigators believe that an appropriate molecular typing method would lead to revolutionary changes in current arrangements of CAP.
Community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA), strains of MRSA that are able to infect otherwise healthy people outside of hospital settings, emerged in the late 1990s and have recently arisen in many countries around the globe. CA-MRSA strains are usually distinguished from their HA-MRSA counterparts by the following characteristics: Firstly, CA-MRSA strains are usually susceptible to non-lactam antibiotics. Secondly, CA-MRSA harbors type IV and V SCCmec elements, which are shorter than the traditional type I, II, and III SCCmec elements found in HA-MRSA strains. Thirdly, certain successful clones are associated with outbreaks of CA-MRSA infections reported in specific geographical locations. For example, ST1 and ST8 isolates are mostly reported in the USA and Canada, ST80 isolates are commonly found in Europe, and ST59 isolates are encountered in the Asia-Pacific region. Notably, all these characteristics have substantial limitations for discriminating CA-MRSA isolates due to their complex backgrounds. Although there were more and more studies of CA-MRSA in European countries and the US, few national epidemiological data were available about China. In this study, we investigated the epidemiological, clinical and molecular characteristics of CA-MRSA isolates recovered in Chinese hospitals, in order to understand the changing epidemiology of MRSA in China.
