Long-Term Prophylactic Antibiotic Treatment: Effects on Survival, Immunocompetence and Reproduction Success of Parasemia plantaginis (Lepidoptera: Er…
2016
Hundreds of insect species are nowadays reared under laboratory conditions. Rearing of insects always implicates the risk of diseases, among which microbial infections are the most frequent and difficult problems. Although there are effective prophylactic treatments, the side effects of applied antibiotics are not well understood. We examined the effect of prophylactic antibiotic treatment on the overwintering success of wood tiger moth (Parasemia plantaginis) larvae, and the postdiapause effect on their life-history traits. Four weeks before hibernation larvae were treated with a widely used antibiotic (fumagillin). We monitored moths' survival and life-history traits during the following …
Rapid induction of immune density-dependent prophylaxis in adult social insects.
2009
The innate immune system provides defence against parasites and pathogens. This defence comes at a cost, suggesting that immune function should exhibit plasticity in response to variation in environmental threats. Density-dependent prophylaxis (DDP) has been demonstrated mostly in phase-polyphenic insects, where larval group size determines levels of immune function in either adults or later larval instars. Social insects exhibit extreme sociality, but DDP has been suggested to be absent from these ecologically dominant taxa. Here we show that adult bumble-bee workers ( Bombus terrestris ) exhibit rapid plasticity in their immune function in response to social context. These results sugges…
Receiving Continuous Antibiotic Prophylaxis
2020
Abstract Continuous antibiotic prophylaxis represents an initial management strategy for decreasing the risk of urinary tract infections in children with vesicoureteral reflux. A significant number of cases resolve spontaneously in time, reason for which continuous antibiotic prophylaxis is not required in every patient with this disorder. It is mandatory to select the patients who need continuous antibiotic prophylaxis according to their risk group. We do not have a lot of scientific evidences about what is better or not for these patients, but the main objective for the case management is to maintain the renal function, by minimizing the risk of pyelonephritis, renal scars and its consequ…
Primary prophylaxis of invasive fungal infections with posaconazole or itraconazole in patients with acute myeloid leukaemia or high-risk myelodyspla…
2017
This is an observational-retrospective study comparing the real-world outcomes associated with posaconazole vs. itraconazole as prophylaxis treatments. Two hundred and ninety-three patient admissions attributable to 174 patients were included in the study. Patients were treated with itraconazole (n = 114 admissions; 39%) or posaconazole (n = 179; 61%). Antifungal prophylaxis failure (APF) due to treatment-related adverse events (in 34 out of 293 patient admissions; 11.6%) was more frequent in the posaconazole group (6.1% vs. 15.1%; P = 0.024). There were 9 patient admissions for episodes of APF due to probable/proven breakthrough fungal infection (primary endpoint): 6 and 3 in the itraconaz…
Predicting invasive fungal disease due to Candida species in non-neutropenic, critically ill, adult patients in United Kingdom critical care units.
2016
BACKGROUND: Given the predominance of invasive fungal disease (IFD) amongst the non-immunocompromised adult critically ill population, the potential benefit of antifungal prophylaxis and the lack of generalisable tools to identify high risk patients, the aim of the current study was to describe the epidemiology of IFD in UK critical care units, and to develop and validate a clinical risk prediction tool to identify non-neutropenic, critically ill adult patients at high risk of IFD who would benefit from antifungal prophylaxis. METHODS: Data on risk factors for, and outcomes from, IFD were collected for consecutive admissions to adult, general critical care units in the UK participating in t…
Invasive candida infections in neonates after major surgery: Current evidence and new directions
2021
Infections represent a serious health problem in neonates. Invasive Candida infections (ICIs) are still a leading cause of mortality and morbidity in neonatal intensive care units (NICUs). Infants hospitalized in NICUs are at high risk of ICIs, because of several risk factors: broad spectrum antibiotic treatments, central catheters and other invasive devices, fungal colonization, and impaired immune responses. In this review we summarize 19 published studies which provide the prevalence of previous surgery in neonates with invasive Candida infections. We also provide an overview of risk factors for ICIs after major surgery, fungal colonization, and innate defense mechanisms against fungi, a…
Cytomegalovirus infection management in solid organ transplant recipients across European centers in the time of molecular diagnostics: An ESGICH sur…
2017
Background Scant information is available about how transplant centers are managing their use of quantitative molecular testing (QNAT) assays for active cytomegalovirus (CMV) infection monitoring in solid organ transplant (SOT) recipients. The current study was aimed at gathering information on current practices in the management of CMV infection across European centers in the era of molecular testing assays. Methods A questionnaire-based cross-sectional survey study was conducted by the European Study Group of Infections in Immunocompromised Hosts (ESGICH) of the Society of Clinical Microbiology and Infectious Diseases (ESCMID). The invitation and a weekly reminder with a personal link to …
Patient perception about the need for antibiotics after tooth extractions: A cross-sectional study
2021
Background: Although the current scientific literature does not support the routine use of antibiotics after dental extractions, patients believe that these drugs offer clear benefit during the postoperative period. The main objective of this study was to describe patient perception of the need for antibiotics after routine tooth extraction and to assess knowledge about the benefits and adverse effects of antibiotic therapy. Material and methods: A cross-sectional study was carried out. A total of 452 participants requiring tooth extraction and seen in the Dental Clinic of the University of Barcelona (Barcelona, Spain) were given a specific questionnaire on the need for antibiotics after de…
ANTITHROMBOTIC PROPHYLAXIS IN LAPAROSCOPIC CHOLECYSTECTOMY
2013
Pulmonary thromboembolism is a common cause of in-hospital death. In moderate or high risk patients undergoing laparotomy, acute and long-term mortality can be effec-tively reduced with an appropriate prophylactic drug treatment, while in low-risk patients undergoing laparoscopy, the correlation between the thromboembolism risk and the pro-cedure itself, as well as potential benefits of thromboprophylaxis are, at present, unclear. Here we report the case of E., a 49-year-old woman with patent foramen ovale, consid-ered to be at low risk of thromboembolism, who experienced a sudden cardiopulmonary arrest following a laparoscopic cholecystectomy and died four days later. . The purpose of this…
Immunogenicity and safety of a nine-valent human papillomavirus vaccine in women 27–45 years of age compared to women 16–26 years of age: An open-lab…
2021
Abstract: Background: Efficacy of the nine-valent human papillomavirus (9vHPV; HPV types 6/11/16/18/31/33/45/52/58) vaccine was demonstrated in a phase 3 study in women 16 & ndash;26 years of age. We present a phase 3 immunogenicity and safety study of the 9vHPV vaccine in women 27 & ndash;45 versus 16 & ndash;26 years of age. Methods: This international, open-label study (NCT03158220) was conducted in women 16 & ndash;45 years of age. Participants (16 & ndash;26 years, n = 570 and 27 & ndash;45 years, n = 642) received a three-dose 9vHPV vaccination regimen (day 1, month 2, month 6). Month 7 geometric mean titers (GMTs) and seroconversion percentages to anti-HPV 6/11/16/18/31/33/45/52/58 w…
