Detection of Babesia species in questing Ixodes ricinus ticks in England and Wales.

Babesiosis, a disease in humans and animals is caused by piroplasms from the genus Babesia and is transmitted by ixodid ticks. Bovine babesiosis, commonly called redwater fever, is reported in cattle from many regions of the British Isles. The presence of Babesia in questing ticks in the United Kingdom (UK) and its potential impact on public and animal health has not been widely studied. Therefore, this study aimed to assess the presence of Babesia spp. in England and Wales using ticks collected over a six-year period. Questing Ixodes ricinus nymphs were collected at 20 recreational areas between 2014 and 2019 and screened for Babesia. Of 3912 nymphs tested, Babesia spp. were detected in 15, giving an overall prevalence of 0.38% [95%CI: 0.21-0.63%]. A number of Babesia species were identified including B. venatorum (n = 9), B. divergens/capreoli (n = 5) and B. odocoilei-like species (n = 1). Based on the low prevalence of Babesia detected in questing I. ricinus nymphs in the recreational areas studied, the likelihood of exposure to Babesia-infected ticks is lower compared to other pathogens more widely studied in the UK (e.g. Borrelia burgdorferi s.l.). However, localized areas of elevated risk may occur in pockets in England and Wales.

Hepatitis B infections among blood donors in England between 2009 and 2018: Is an occult hepatitis B infection a risk for blood safety?

INTRODUCTION: Hepatitis B virus (HBV) is one of the most frequent infections identified in blood donors in England and represents an ongoing blood safety risk. We have analyzed markers of HBV infections in blood donors in England between 2009 and 2018 and used these to estimate the likelihood of non-detection of occult HBV infection (OBI). METHODS: We collected epidemiological, virological, and genotyping information on HBV cases identified in England, 2009-2018. The estimated risk of non-detection and likely transmission of OBI were compared to lookback and transfusion-transmitted infections surveillance data. RESULTS: Six-hundered and fifty-five HBV-infected blood donors were identified in England during the 10-year period; 598 chronic, 32 acute, and 25 occult HBV infections. However, most donors with chronic and occult infections were born in Eastern Europe, Africa, or Asia (451/544, 83% and 14/24, 58%); acute infections were largely seen in UK-born donors (19/28, 68%). Genotyping of 266 HBV-positive samples revealed five genotypes (A-E), reflecting ethnicity and country of birth. Most OBIs were identified in repeat donors (19/25); lookback data identified a transmission rate of 8.3%. It is estimated that at least 13 potentially infectious donations from donors with OBI remain undetected annually, equating to an overall residual transmission risk of 3.1 per million donations using our current screening strategy of HBsAg screening with HBV nucleic acid testing (NAT) in pools of 24. CONCLUSIONS: OBI accounted for the majority of the HBV residual risk in England. Further cost-benefit analysis is required to estimate if our current HBV screening strategy should be changed.

Trauma and Intensive Care Nursing Knowledge and Attitude of Foley Catheter Insertion and Maintenance.

In the acute care setting, the majority of urinary tract infections are associated with indwelling urinary catheters. Despite guidelines for proper use, catheter-associated urinary tract infections (CAUTIs) continue to occur in critically ill/injured patients. There is a paucity of data on the translation between CAUTI prevention education and behavioral change. This project evaluated nurse's clinical knowledge and attitude toward Foley catheter insertion and maintenance to determine the benefits of addressing gaps in knowledge and inconsistencies in attitude through education.A prospective cohort study was conducted with registered nurses from the emergency room, trauma/surgical, and medical intensive care units. Participant's clinical knowledge and attitude toward Foley catheter usage and CAUTIs were evaluated using a 20-question survey tool before and after a CAUTI education program.Forty-eight nurses completed the presurvey, educational training, and postsurvey. The mean postsurvey score was significantly higher (86.9 ± 8.3%) than the presurvey score (76.0 ± 12.3%) for the knowledge section of the survey. There was no marked difference in participant attitude following the educational training, with mean presurvey and postsurvey scores of 91.3 ± 7.0% and 89.8 ± 5.3%, respectively. After the course, participants were more confident in their clinical knowledge; however, perception regarding CAUTI prevention did not improve. A series of unannounced rounding observations before and after the intervention showed an improvement in proper Foley catheter maintenance.Catheter-associated urinary tract infection prevention education was an effective countermeasure to address gaps in clinical knowledge, but modifying attitudes was difficult to achieve. In the short term, the training appeared to improve proper maintenance in clinical practice.
