Filter by:Pancreaticoduodenectomy is associated with high perioperative morbidity, with surgical site infection (SSIs) being one of the most common complications. A retrospective study at Hopkins on SSIs in these patients identified the rate of SSIs to be 16.7% and pre-operative bile stent/drain and neoadjuvant chemotherapy were independent predictors of surgical site infection. Patients with these factors having a predicted risk of up to 32%. Another subsequent retrospective study demonstrated that the use of negative pressure wound therapy device was significantly associated with a decrease in the rate of SSIs. The hypothesis of the investigator(s) for the current study is that placement of Prevena Peel & Place Dressing (Negative Pressure Wound Therapy, NPWT) in patients undergoing pancreaticoduodenectomy who are at high risk of SSIs will result in a significant decrease in their SSI rate.
The main focus of this observational study is to analyze the possible effects of cranberry dietary supplements on the intestinal microbiota in women with recurrent uncomplicated urinary tract infections. In a secondary analysis the possible influence of the microbiota changes on the recurrence frequency in the follow-up should be analyzed.
RCT to evaluate the safety and efficacy of Lactobacillus reuteri DSM 16666 & Lactobacillus reuteri DSM 17938 to significantly modify the frequency of clinical or bacteriological cure in women with non complicated acute cystitis who receive probiotics for 12 days compared with the frequency in women who receive placebo.
This is a phase I study that will assess the acquisition of immunity to Pf malaria over the course of 5 sequential Controlled Human Malaria Infections (CHMI) over 2-4 years, in 10 healthy adult participants. 10 subjects will initially be challenged with 5 uninfected mosquitoes (mock), followed by 5 challenges with 5 mosquitoes infected with drug sensitive, P. falciparum parasites (strain NF54) 2, 8, 14-20, 20-32, and 32-36 months later. For the final four infective CMHIs six additional immunologic malaria-naïve subjects will be enrolled and challenged as infectivity controls. If dropouts occur within the original 10 person cohort, and two or more CHMI remain, back-up replacement volunteers will be recruited to undergo successive CHMI with the core group. All volunteers (repeat CHMI subjects and infectivity controls) will be evaluated as part of an inpatient stay (or outpatient daily follow-up) to diagnose Pf malaria infection and treat with Coartem(R) (artemether/lumefantrine) or Malarone(R) (Atovaquone/proguanil). Daily observation will occur from Study Days 9-19 or until three-day directly observed therapy for P. falciparum infection is complete and two negative smears separated by a time interval >12 hours have been documented. A third negative smear >12 hours after the previous two daily smears will be documented to affirm malaria cure. Infectivity Controls enrolled as part of CHMI #5 will be treated based on concomitant us qPCR results. The repeat CHMI subjects will have additional outpatient visits days 1, 3, 5, and 7 after the challenge to obtain blood samples to monitor the development of immunity. The study is expected to last for 48 months and will include approximately 34 healthy male and female volunteers (10 active study volunteers and 18 naïve controls to confirm Pf infectivity during the 2nd -5th CHMI challenges) ages 18 to 50 years, inclusive, from the greater Baltimore community. The primary objective of this study is to determine whether protective immunity against parasite infection develops following repeat CHMI.
The clinical trial will investigate the effect of different formulations of ARA + 0.4% DHA in infant formula on plasma fatty acid status in healthy 6 months old infants supplemented for 6 months. A 6-month follow on phase will provide additional efficacy (e.g. infection rates, immune markers) and safety information in these 12-18 month old infants.
Gut dysbiosis is an intestinal disorder that is characterized by accumulation of microbiota imbalance, host-microbiota crosstalk dysfunction and inflammation. As part of its clinical development, MaaT (Microbiota as a Therapy) Pharma is particularly interested in patients with Bone and Joint Infections (BJI). These patients are treated with antibiotics having significant consequences on their intestinal flora, causing intestinal discomfort, which can be manifested by diarrhea. MaaT Pharma wishes to carry out a clinical study, OSIRIS, in collaboration with Prof. Tristan Ferry, member and coordinator of CRIOAc (Centre de Référence des Infections Ostéo-Articulaires Complexes) Lyon, Center of Reference of Bone and Joint Infections (BJI). The objective of this study is to follow patients with treated BJI in order to characterize intestinal dysbiosis and the future relevance of an autologous Fecal Microbiota Transplantation (aFMT) intervention. To do this, patients will be monitored according to the current CRIOAc recommendations, with the aim of taking biological samples from patients at the same time as scheduled visits, routine monitoring patients. Only one additional consultation will be carried out 15 days after stopping the antibiotics in order to better evaluate the dysbiosis evolution. Thus biological samples (blood, stool, nasal, rectal) will be taken during the follow-up consultations over a period of 6 months.
Pressure ulcer represents a frequent clinical condition in patient with spinal cord injury or after prolonged Intensive Care Unit (ICU) stay. Osteomyelitis constitutes a severe complication with a poorly known management, and is associated with a high rate of relapse, leading to a high-burden in hospital bed-days, financial cost, surgical intervention, antibiotic use, morbidity and mortality, and nursing care. In our reference center for bone and joint infection management, the medical and surgical strategies are systematically discussed during pluridisciplinary meetings. Most patients benefit from a two-stage surgical strategy (debridement with initiation of vacuum-assisted closure therapy until reconstruction using muscular flap) with prolonged antimicrobial therapy. In this context, our study aims to evaluate this complex approach and to determine risk factors of treatment failure in order to improve patient management, focusing on optimization of empirical antimicrobial therapy after each surgical stage, delay between the two surgical stage, and duration of antimicrobial therapy.
Late diagnosed HIV-infected subjects show impaired immunological recovery resulting in a greater risk of clinical progression. Gut bacteria metabolism appears to impact immune recovery in HIV-infected subjects, and while nutritional interventions with prebiotics and probiotics seem to exert immunological effects, the clinical implications in this key population remain unknown. This is a pilot multicenter randomized placebo-controlled, double blind clinical trial in HIV-infected ART-naive subjects with <350 CD4 T cells/mm3 or AIDS. Participants will be randomized (1:1) to either the synbiotic nutritional supplement PMT25341 or placebo for 48 weeks, each in combination with first-line ART. Primary outcomes will be safety and immunological recovery. Secondary outcomes will include changes in fecal microbiota structure and plasma inflammatory markers.
The primary objectives of this study are to evaluate the antiviral efficacy, safety, and tolerability of sofosbuvir/velpatasvir (SOF/VEL) fixed-dose combination (FDC) with or without ribavirin (RBV) for 12 weeks in adults with chronic hepatitis C virus (HCV) infection and decompensated cirrhosis.
Background: People get Zika virus from infected mosquitos. They usually don t get very sick. But birth defects were reported in babies born to mothers who had Zika infection. In rare cases, people with Zika infection had a nervous system disease that causes severe muscle weakness and can be life threatening. A new vaccine made from DNA in the code for a Zika virus protein could help the body build an immune response against the virus. Objectives: To see if a new vaccine against Zika virus disease is safe and causes any side effects. To study specific immune responses to the vaccine. Eligibility: Healthy people ages 18-50 Design: Participants will be screened with: Medical history Physical exam Urine tests Participants will have 18 visits over 2 years. Participants will be randomly assigned to 1 of 3 groups. All will get 3 vaccines at 3 separate monthly visits. They will receive the vaccine in the upper arm muscle. Some will get it by needle and syringe, others by a device that uses high pressure to push the vaccine through the skin. Vaccine visits last 4-6 hours. Participants will get a thermometer to measure their temperature and a ruler to measure any skin changes at the injection site. They will record this data for 7 days after each injection. Other visits last 1-2 hours. These include: Evaluation of any health changes or problems Blood tests: Some samples may be used for future research. Participants with side effects may have extra visits. ...
