07-1.21; P<0.0001, I =75%). Susceptibility-guided therapy was superior to first-line clarithromycin-based triple therapy only when clarithromycin resistance exceeded 20% (RR, 1.18; 95% CI, 1.07-1.30; P=0.001, I =81%). Susceptibility-guided therapy was not more effective than empirical quadruple therapy (RR, 1.02; 95% CI, 0.92-1.13; P=0.759, I =80%). Three RCTs were performed exclusively among previously treated subjects, and were highly heterogeneous. Our findings suggest that susceptibility-guided treatment may be slightly superior to empirical first line triple therapy. Susceptibility- guided treatment does not appear to be superior to empirical first-line quadruple therapy or empirical rescue therapy.

The negative impact of disproportionate growth in premature infants is well documented, but optimal nutrition practices needed to prevent unhealthy body mass indices remains unclear. An evidence-based volume increase guideline advanced feeding volumes from 150-160 to 170-180 milliliters per kilogram per day (ml/kg/d), between the post menstrual age (PMA) of 31 0/7 and 34 0/7 weeks was implemented in October 2017 for infants born ≤ 32 0/7 weeks GA. Data was collected on 262 infants' weight and length at birth and at discharge for 20 months before and 21 months after guideline implementation and retrospective analysis was conducted to determined disproportionate growth by comparing body mass indices [BMI (in g/cm )] at birth and at discharge. Changes in infants' body habitus were determined through bivariate analysis of weight and length z-scores from the Fenton growth curve. Implementation of a targeted volume nutrition guideline resulted in a reduction in infants with growth failure, defined as weight <10 percentile, (19.5% vs. 11.2% p = 0.06) at discharge. Infants who received the targeted nutrition guideline had a statistically significant reduction in disproportionally low BMI (8.6% vs. 2.5% p = 0.0380) and an increase in disproportionately high BMIs (4.3% vs. 12.3% p = 0.025). There was minor change in the percentage of disproportionately large infants who received the guidelines from birth to discharge (11.5% vs 12.3%). A targeted volume increase nutrition guideline may prevent growth failure with some effects on disproportionate growth in preterm infants born ≤ 32 0/7 weeks gestational age.

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). 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. 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. 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.

Conventionally, cytokines require an inductive stimulus for their expression and secretion, resulting in a time lag from the time of stimulation to when the proteins are packaged and secreted. Because cytokines are the main communicators in the immune system, their temporal expression is a key factor in coordinating responses to efficiently resolve infection. Herein, we identify that circulating human monocytes contain preformed cytokines that are stored intracellularly, in both resting and activated states. Having preformed cytokines bypasses the time lag associated with de novo synthesis, allowing monocytes to secrete immune mediators immediately upon activation or sensing of microbe-associated molecular patterns. We demonstrate here that, out of several cytokines evaluated, human monocytes contain a previously undescribed reservoir of the preformed chemokine CCL5. Furthermore, we showed that CCL5 could be secreted from monocytes treated with the protein synthesis inhibitor (cycloheximide) and Golgi blocker (brefeldin A). We examined the possibility for uptake of extracellular CCL5 from platelet aggregates and observed no significant levels of platelet binding to our enriched monocyte preparations, indicating that the source of preformed CCL5 was not from platelets. Preformed CCL5 was observed to be distributed throughout the cytoplasm and partially colocalized with CD63+ and Rab11A+ membranes, implicating endosomal compartments in the intracellular storage and trafficking of CCL5.
