Mechanism and Immune Function Analysis of SARS-CoV-2 Infection in Hematologic Tumors
SARS-CoV-2 InfectionHematologic MalignancyThe goal of this observational study is to compare the immune function and infection mechanism of patients with hematologic tumors and those people without underlying diseases after infection with SARS-CoV-2. Clinical characteristics, treatment options and responses will be collected. Peripheral blood will be collected from patients with hematologic tumors infected with SARS-CoV-2 and those people without underlying diseases infected with SARS-CoV-2.

Prediction of Multidrug-resistant Bacterial Infection in Patients With Cirrhosis
Drug ResistanceMultiple2 moreThe aim of this study is to identify predictive factors of infections caused by multidrug-resistant organisms in patients with cirrhosis and to develop and validate (internally and externally) a predictive model that might be useful to use in clinical settings to stratify the risk and lead clinical decision-making strategies.

A Study to Investigate Acute Respiratory Virus Infections in Participants at High Risk for Severe...
Acute Respiratory Viral InfectionThe purpose of the study is to describe the rate of occurrence of clinical diagnosis of acute respiratory infection (an infection that affects normal breathing) and different types of respiratory pathogens (harmful organisms) of new respiratory infections in a population at high risk for severe illness.

MeMed BV® Test Evaluation in Adult Emergency Department Patients
Respiratory InfectionRespiratory Infections in Old Age2 moreThe goal of this observational study is to compare the results of a serum biomarker called the MeMed BV®, which is approved to help differentiate between bacterial and viral respiratory infections, to clinical diagnoses of adult emergency department patients presenting with recent fever and signs or symptoms of a respiratory infection. Active participation is completed during the emergency department visit and includes drawing blood, obtaining a sputum sample, and answering survey questions.

Comparison of Two Rescue Therapies for Helicobacter Pylori Infection
Helicobacter Pylori InfectionFrom the profiles of antibiotic susceptibility data following eradication therapy, tetracycline, amoxicillin and levofloxacin are all good candidates of antibiotics used in the rescue treatment.

Clostridium Difficile InfectionThe purpose of this study is to compare number of vegetative cells and spores in stool over time for fidaxomicin or vancomycin in patients diagnosed with their first episode of C. difficile infection.

Study Comparing the Safety and Efficacy of Intravenous CXA-201 and Intravenous Levofloxacin in Complicated...
Complicated Urinary Tract InfectionPyelonephritisThis is a Phase 3, multicenter, prospective, randomized, double-blind, double dummy study of CXA 201 IV infusions (1500 mg q8h) versus levofloxacin IV infusions (750 mg qd) for the treatment of adults with a cUTI (including pyelonephritis).

Efficacy Study of Delayed Primary Closure to Reduce Rate of Wound Infection in Complicated Appendicitis...
Surgical Site InfectionResearch hypothesis: Does delayed primary wound closure after appendectomy in adults with complicated appendicitis reduce postoperative superficial surgical site infection compare to primary wound closure. Study design: This study is a multicenter randomized controlled trial of delay versus primary wound closure in complicated appendicitis. Setting: Thammasat Hospital, Ramathibodi Hospital, Chonburi Hospital, Chonpratarn Hospital, Vachira Hospital, and Pathumthani Hospital Participants: Adult patients age 18 years or older and non-pregnant in women who have been diagnosed as gangrenous or ruptured appendicitis. Outcome: Superficial surgical site infection Period of study: August 2012 - August 2014

Study of CB-183,315 in Participants With Clostridium Difficile Infection
Clostridium Difficile InfectionDiarrheaThis is a randomized, double-blind, single-placebo, active-controlled, dose ranging parallel group design with 3 arms. Two dose regimens of CB-183,315 dosed twice daily will be compared with the active comparator oral vancomycin (125 milligrams (mg ) four times daily). Participants with diarrhea at risk for Clostridium difficile infection (CDI) [for example, received prior or concomitant antibiotic(s)] will be identified and tested for C. difficile toxin in stool using an enzyme immunoassay (EIA), or polymerase chain reaction (PCR) per the usual standard of care. Eligible participants will be consented, undergo baseline evaluations, and will be randomized in a blinded fashion to one of 3 treatment arms. Participants will be randomized to receive either 125 mg CB-183,315 twice daily alternating with placebo tablets twice daily, 250 mg CB-183,315 twice daily alternating with placebo tablets twice daily or 125 mg oral vancomycin four times dailyover a period of 10 days in a 1:1:1 fashion.

Impact of Infectious Diseases Specialists on the Appropriateness of Antimicrobial Therapy in Emergency...
Patients Under Antimicrobial TherapyCONTEXT: Antibiotics are frequently used in hospital but the appropriateness of prescriptions ranged between 25-50%. The intervention of infectious disease specialists (IDS) could improve the appropriateness of prescriptions and reduce their use. The impact of IDS has not been yet fully estimated using a randomized trial to compare the quality of care of patients who will benefit of the intervention. OBJECTIVES: To show using a randomized trial that patients hospitalized in emergency wards with IDS advice will receive more appropriate antimicrobial therapy but less exposure to antibiotics, as compared to patients who will not receive IDS advice. METHODS: Prospective randomized trial comparing antibiotic exposure and appropriateness of prescriptions in two groups of patients admitted in emergency wards: Control group: antibiotic prescriptions will be initiated and managed by the attending physicians Intervention group: antibiotic prescriptions will be systematically evaluated by the IDS and changed if judged necessary by the attending physicians, following IDS' advice. STUDY PROCESS: The study will took place in the emergency wards of 4 university hospitals. For each ward, the period of the study will be 2 x 4 weeks.Total duration of the study: 12 months.
