Abstract
Acute upper respiratory tract infections (URTIs) are caused by numerous viruses and bacteria. URTIs can be a cause of morbidity and are among the most common reasons for visiting healthcare practitioners and prescribing antibiotics to children in addition to causing absenteeism from school and work. Oral intake of Lacticaseibacillus rhamnosus GG DSM 33156 has shown beneficial health effects in several clinical trials, primarily relating to immune function and gastrointestinal health in children and adults. It has also been suggested that oral intake of L. rhamnosus GG DSM 33156 can reduce the incidence rate and alleviate symptoms of URTIs in children. We here report the results of a randomised, double-blind, placebo-controlled trial of 619 children aged 2-6 years conducted at a single centre in Scotland. The children, who were in day care or primary school, were followed over a 16-week intervention period with 309 randomised in the active group and 310 in the placebo group. The parents or guardians reported a daily healthcare status and any presumed episodes of URTI, which were subsequently confirmed by a general practitioner. The investigational product was well tolerated in the trial. Although a general trend towards a beneficial effect was observed, this trial did not demonstrate that L. rhamnosus GG DSM 33156 significantly reduced the incidence of URTIs, diagnosed by a general practitioner according to prespecified criteria (primary endpoint). Moreover, none of the secondary efficacy endpoints were met. Applying a Ward's hierarchical clustering, two separate clusters, focussing on four quality of life-related endpoints, were identified. Cluster 1 was associated with more severe URTI characteristics than cluster 2. Cluster 2 was significantly enriched with children who consumed the product, indicating that the symptoms children experience during an URTI are alleviated by the intake of L. rhamnosus GG DSM 33156. The study is registered at ClinicalTrials.gov ID: NCT03636191.

Abstract
33 Background: To this day, no therapy has proven efficacy in the clinical management of PSA relapse non-metastatic CRPC. Investigating novel therapeutic agents that will induce a PSA response, and delay progression to overt metastases is of paramount importance. Methods: A single arm multi-center phase II clinical trial is being conducted. Inclusion criteria are PSA only progression despite androgen deprivation therapy, defined as three rising PSA levels with a measurement interval of at least 2 weeks, and minimum PSA level ≥ 1 ng/mL. Patients with radiologic evidence of bone metastases were excluded. Bevacizumab single agent was administered at 10 mg/kg every 14 days. PSA was evaluated at least every 6 weeks and bevacizumab was continued until PSA progression or new metastasis. Results: 15 patients (see Table ) have been enrolled on this ongoing trial. Toxicities observed were grade 4 pulmonary embolism, grade 3 hypertension, and grade 3 proteinuria in one patient each, but no treatment related mortality. Median treatment duration was 12.6 weeks (range 11–33.1 wks). 12 patients are evaluable for PSA response. Four patients had PSA decline of 14, 20.9, 24, and 45% respectively. Median PSA doubling time during bevacizumab increased to 5.93 months (range 0.81–27.09 months) from pretherapy median of 4.08 months, a 45% improvement. Five patients have progressed to develop bone metastases at median of 7.7 months (range 2.8–18.2) after protocol registration. Conclusions: Bevacizumab was well tolerated, and impacted PSA kinetics in non-metastatic CRPC. Further investigations are warranted. Supported in part by Genentech Inc.

Abstract
152 Background: Satraplatin is an oral platinum that has demonstrated efficacy and tolerability in metastatic CRPC. Bevacizumab has revealed safety and efficacy in advanced prostate cancer, and synergy was noted between platinum based chemotherapy and B. Methods: Primary endpoint was time to progression (TTP). Latter wasdefined per RECIST 1.0 or onset of a skeletal event, or > 2 new areas of bone metastases. DP metastatic CRPC patients were eligible. S 80mg/m2 orally on days 1-5, P 5 mg twice daily, and B 10mg/kg on day 1, and 15mg/kg on day 15 were administered in 35 day cycles. Results: 31 patients enrolled (13 African American and 18 Caucasian) to complete accrual. Median age was 67 years (range 50-85 years) and 21 patients (68%) were > 65 years of age. Median pretherapy PSA was 180.7 ng/ml (range 4.7-1,433 ng/ml). 21 (68%) had bone pain, Gleason score was > 8 in 20 (65%) patients. Pretherapy 12 patients had measurable disease progression, 17 (55%) had bone scan progression, and 8 had PSA only progression. 176 cycles have been administered; median 4 cycles (range 0-12 cycles). Grade 4 toxicities noted were, pulmonary embolism in 2 patients and thrombocytopenia in 1 patient. Grade 3 toxicities observed were neutropenia and hypertension in 3, anemia in 7 and , thrombocytopenia and diarrhea in 2 patients each. No treatment related deaths. 29 patients are response evaluable to date; 10 (34%) had a ≥30% PSA decline and 3 (10%) had a > 90% PSA decline. Of 12 patients with MD, 2 had a response and 7 had stable disease. Median TTP was 7.4 months (90% CI 4.8-12.8 months) and median survival was 11.2 months (90% CI 9.1-18.3 months). 47% of patients were alive at 12 months. Genotype characterization for excision repair cross-complementation group 1 (ERCC1) polymorphism was performed in 17 patients with 9 having homozygous (CC), 3 with heterozygous, (CT) and 2 patients with absence of ERCC expression respectively. Conclusions: The combination was tolerable and revealed promising efficacy in metastatic CRPC. ERCC1 testing will be correlated with outcome endpoints.

Abstract
e16028 Background: In metastatic CRPC, second line therapy after docetaxel, remains a currently unmet need. Based on the efficacy and tolerability of S and B in prostate cancer, and the clinical synergy noted between chemotherapy and B, a phase II trial of the combination was conducted. Methods: Metastatic CRPC patients, with prior docetaxel based chemotherapy were eligible to receive S 80 mg/m2 orally for days 1–5, and B 10 mg/kg on day 1, and 15mg/kg on day 15 of each 35 day cycle. Prednisone was administered at a dose of 5 mg twice daily. Response was assessed every 2 cycles. Toxicity was assessed weekly during cycle 1 and on days 1 and 15 of each subsequent cycle. Primary endpoint was time to progression defined as a skeletal event, new areas of metastases on bone scans or per RECIST criteria for measurable disease. Results: 19 of 28 patients have been enrolled to date; 7 African American and 12 Caucasian,, with median age of 68.5 years and median pretherapy PSA of 137.8 ng/mL (range 16.8–994 ng/mL). 7 (44%) had bone pain, Gleason score of 7 and ≥ 8 in 7 and 12 patients respectively. Measurable disease progression was noted in 5 patients, bone scan progression in 6 patients, progression of both in 3 patients, and PSA only progression in 5 patients. 76 cycles have been administered; 7 patients continued on therapy beyond 6 cycles. The only grade 4 toxicity noted was pulmonary embolism in 2 patients, after 2 and 6 cycles of therapy. Grade 3 neutropenia, gastrointestinal toxicity, and electrolyte abnormalities were noted in 1 patient each. There were no treatment related deaths. 16/19 patients are response evaluable. 7 patients had a PSA decline of which 4 patients had a ≥30% PSA decline. 3 of 6 patients had a measurable disease response. 11 of 16 patients have progressed to date after median of 6 cycles of therapy. Time to progression and survival data will be reported. Conclusions: The combination was well tolerated, and revealed preliminary evidence of clinical efficacy in docetaxel pretreated metastatic CRPC. [Table: see text]

Abstract
Zygosaccharomyces bailii possesses a constitutive malic enzyme, but only small amounts of malate are decomposed when the cells ferment fructose. Cells growing anaerobically on glucose (glucose cells) decompose malate, whereas fructose cells do not. Only glucose cells show an increase in the intracellular concentration of malate when suspended in a malate-containing solution. The transport system for malate is induced by glucose, but it is repressed by fructose. The synthesis of this transport system is inhibited by cycloheximide. Of the two enantiomers L-malate is transported preferentially. The transport of malate by induced cells is not only inhibited by addition of fructose but also inactivated. This inactivation is independent of the presence of cycloheximide. The transport of malate is inhibited by uranyl ions; various other inhibitors of transport and phosphorylation were of little influence. It is assumed that the inducible protein carrier for malate operates by facilitated diffusion. Fructose cells of Z. bailii and cells of Saccharomyces cerevisiae do not contain a transport system for malate.

Abstract
The axonal transport, metabolism, and transcellular transfer of uridine, adenosine, putrescine, and spermidine have been examined in intact and regenerating optic nerves of goldfish. Following intraocular injection of labeled nucleosides, axonal transport was determined by comparing left-right differences in tectal radioactivity, and transcellular transfer was indicated by light autoradiographic analysis. The results demonstrated axonal transport, transcellular transfer, and periaxonal cell utilization of both nucleosides in intact axons and severalfold increases of all of these processes in regenerating axons. Experiments in which the metabolism of the nucleosides was studied resulted in data which suggested that uridine and adenosine, when delivered to the tectum by axonal transport, are protected from degradation and thus are relatively more available for periaxonal cell utilization than nucleosides reaching these cells via the blood. In intact axons, the majority of the nonmetabolized radioactivity was present as UMP, UDP, and UTP following [3H]uridine injections, whereas the majority of the radioactivity following [3H]adenosine injections was present as adenosine, with the phosphorylated derivatives constituting a smaller proportion. During nerve regeneration, the relative proportion of nucleosides to nucleotides was reversed, with uridine being the principal labeled compound in the first case, and AMP, ADP, and ATP being the major labeled compounds in the latter case. The nucleosides also were found to be different from each other in that adenosine, but not uridine, can be taken up by optic axons and transported retrogradely from the tectum to retinal ganglion cell bodies in the eye. Following intraocular injection of [3H]spermidine, radioactivity was transported to the optic tectum and transferred to tectal cells in the vicinity of the regenerating axons. Following [3H]putrescine injections, silver grains were found over periaxonal glia, but preliminary findings suggest that they are not present over tectal neurons nor over radial glial cells in the periependymal layers. Analysis of tectal radioactivity showed in each case that it was composed primarily of the injected compounds. These studies indicate that, following axonal transport, the polyamines do not remain within regenerating axons but are transferred to cells surrounding the axon. On the basis of these and previous findings, we speculate that the axonal transport and transcellular transfer of uridine, adenosine, polyamines, and perhaps other small molecules are means of communication between axons and periaxonal cells; that the axon can affect RNA and protein synthesis in periaxonal cells by regulating the availability of these small molecules; and that, during nerve regeneration, the increased metabolic needs of periaxonal cells are met by an increased axonal supply of precursors (adenosine and uridine) and other molecules (polyamines) critical for protein synthesis.
