Chlorhexidine Vaginal Cleansing Versus Iodine Prior to C-section and the Rate of Postoperative Infection...
Vaginal ScrubbingBackground: Women undergoing cesarean delivery have 5 to 20 fold greater risk for infection and infectious morbidity compared with those undergoing vaginal birth. Endometritis, febrile morbidity, and wound infection are the most frequent complications of post cesarean infections. Endometritis accounts for 6-27% followed by clinically significant fever, which was reported about 5-24%,while the incidence of wound infection is about 2-9%.Previous studies evaluated whether vaginal cleansing can reduce the incidence of postoperative infectious morbidity. In most of the studies, povidone iodine was used as intervention. Objectives: The aim of this study is to test the hypothesis that preoperative vaginal cleansing with chlorhexidine would be superior to iodine for the prevention of maternal infectious morbidities including endometritis, fever and wound complications. Methods: This prospective randomized single blinded controlled trial will be conducted at Makassed General Hospital between February 2018 and January 2019. Total of 300 patients, 150 in each group, will be enrolled. Group 1 patients will receive chlorhexidine vaginal cleansing while group 2 patients will receive iodine prior to C-section. Adverse post infectious morbidities such as endometritis, febrile illness and wound infections will be observed within 30 days of C-section.

The Clinical Value of FA in AHLRI Patients
Lower Respiratory Tract InfectionLRTI (Lower respiratory tract infection) is a severe disease in China. The fast and accurate diagnosis of pathogens, bacteria or viruses that cause the infection is critical for the therapy. In this study, investigators assume that the use of FilmArray Respiratory Panel will provide more rapid and comprehensive evidences to physicians to diagnose LRTI which is caused by viruses or atypical pathogens and then reduce the length of antibiotics use by 0.5-1.0 days as well as other hospital resources (length of hospital/ICU stay, take-away oral antibiotics, etc.). Secondly, investigators assume that in LRTI patients with viral infection and a low serum PCT level, fewer length of antibiotics use can be expected. Thirdly, the use of FilmArray Respiratory Panel will provide clearer epidemiology data of virus and atypical pathogens in hospitalized LRTI patients.

Probiotics and Intestinal Microbiome in Preterm Infants
Microbial ColonizationThe gut microbiome plays a significant role in balancing the inflammatory system in the immature gut. A breakdown in this balance with altered colonization of the microbiota in very low birth weight (VLBW) preterm infants is associated with increased feeding intolerance, necrotizing enterocolitis (NEC) and sepsis. Probiotics are proposed to normalize microbial populations and decrease intestinal disease in preterm infants. There is limited data linking clinical outcomes with the biology of probiotics. We aim to study the colonization of the GI tract with probiotic species contained in a specific probiotic blend - Florababy - in VLBW preterm infants. Stool microbiome will be analyzed at 4 time points in 2 groups (one given Florababy and the other no) of infants less than 1000 grams birth weight and < 29 weeks gestation. A comparison of stool microbiome analysis and the incidence of feeding intolerance and time to reach full feeds in the two groups will be made.

Quality of Life and Health Utility of Patients With CHB Infections
Chronic Hepatitis B InfectionThe aim of the study is to assess the health-related quality of life (HRQOL) and preference-based health utilities of chronic hepatitis B (CHB) carriers in different stages of illness. It will also estimate the cost-effectiveness of anti-viral treatments resulting from the prevention of the progression of disease from uncomplicated CHB carriers to cirrhosis and hepatocellular carcinoma (HCC). The following hypotheses will be tested: Patients with chronic hepatitis B virus (HBV) have poorer health-related quality of life (HRQOL) than the general population; Patients with more severe stages of chronic HB infections have lower health related quality of life and health utility values; Anti-viral treatment can improve the HRQOL and health utility for patients with CHB infections; The cost-effectiveness of different treatments for chronic HBV infections can be directly compared in terms of cost/QALY gained.

Understanding the Drivers of Surgical Site Infection: Investigating and Modeling the Swissnoso Surveillance...
Surgical Site InfectionSurgical site infection (SSI) is the most common healthcare-associated infection, multifactorial in nature, and a typical preventable harm. Many healthcare systems require hospitals to determine the corresponding infection rates as a quality indicator and often stipulate public reporting of these data. Several agencies, among them the World Health Organization (WHO) and the U.S. Centers for Disease Control and Prevention (CDC), have issued evidence-based prevention guidelines. Despite efforts in implementing best practice, SSI continue to be a relevant complication of modern surgical procedures and generate enormous costs for the healthcare system. Moreover, prevention guidelines acknowledge that the evidence backing their recommendations is low to moderate in most cases, which is partly due to the complexity of SSI pathogenesis. Swissnoso, the Swiss expert group for infection prevention and hospital epidemiology, oversees the nationwide collection of data on select procedures and the associated SSI. Since the inception of this dedicated surveillance in 2009, more than 300'000 procedures have been included and the corresponding patients were followed to ascertain SSIs. Although primarily conceived as a national surveillance system and then used for public reporting starting in 2014, Swissnoso is a prime data source for better understanding the epidemiology of SSI. Here, the investigators seek to raise the quality of evidence behind future prevention guidelines. For this purpose, the investigators will move from a risk factor analysis for SSI (of which a substantial part occurs after patient discharge from the hospital, rendering surveillance difficult) to the collection of additional data (in order to better characterize certain determinants of SSI and their recognition) and, finally, to a mathematical model (which will simulate the probability of developing SSI so the investigators can test what may modulate this risk).

CMV Infection and Immune Intervention After Transplantation
CMV ViremiaTransplantation InfectionAllogeneic hematopoietic stem cell transplantation (allo-HSCT) is an effective or even the only way to cure blood malignant diseases. Cytomegalovirus (CMV) infection is a serious early complication of allo-HSCT. Its high incidence and poor prognosis can cause a series of terminal organ diseases such as CMV pneumonia, encephalitis, and enteritis,which seriously affecting the prognosis of patients post allo-HSCT. Our data show that rapid reconstruction of NK cells after transplantation can reduce the incidence of CMV infection. Patients with a rapid reconstruction of NKG2C after transplantation have a low CMV infection rate, and patients with strong secretion of IFN-gamma of NK after transplantation have low CMV infection. Our previous research showed that trophoblast cells transfected with IL-21 and 4-1BBL can achieve a large number of clinical-grade expansion of NK cells (mIL-21 / 4-1BBL NK cells), and mIL-21 / 4-1BBL NK cells It is safe to treat patients with minimal residual disease (MRD) positive AML after transplantation, and can induce MRD to turn negative. Previous studies have shown that adoptive infusion of expanded NK cells after haplotype transplantation is safe and can improve the functional reconstruction of NK cells. Therefore, we hypothesized that the infusion of NK cells can improve the antiviral capacity of NK cells, thereby effectively reducing the CMV infection. Incidence.
