Abstract
PURPOSE/OBJECTIVE(S) Radiotherapy (RT) following breast conserving surgery (BCS) for ductal carcinoma in situ (DCIS) reduces invasive and in situ recurrences. Whereas landmark studies suggest that a tumor bed boost improves local control for invasive breast cancer, the benefit in DCIS remains less certain. We evaluated outcomes of DCIS patients treated with or without a boost and hypothesized that a tumor bed boost would improve locoregional control rates. MATERIALS/METHODS The study cohort comprised patients with DCIS who underwent BCS at our institution from 2004-2018. Clinicopathologic features, treatment parameters and outcomes were ascertained from medical records. Patient and tumor characteristics were evaluated relative to outcomes using univariable and multivariable Cox models. Recurrence-free survival (RFS) estimates were generated using the Kaplan Meier method. RESULTS We identified 1675 patients who underwent BCS for DCIS (median age 56 [interquartile range (IQR) 49, 64]). Boost RT was employed in 68% of cases (n = 1146) and endocrine therapy in 32% (n = 536). At a median follow-up of 4.2 years (IQR 1.4, 7.0), we observed 61 locoregional recurrence events (56 local, 5 regional) and 21 deaths. Univariable logistic regression demonstrated that boost RT was more common among younger patients (p<0.001) with positive/close margins (p<0.001), and with larger tumors (p<0.001) of higher grade (p = 0.025). The 10-year RFS rate was 88.8% among those receiving a boost and 84.3% among those without a boost (p = 0.3), and neither univariable nor multivariable analyses revealed an association between boost RT and locoregional recurrence. CONCLUSION Among patients with DCIS who underwent BCS, use of a tumor bed boost was not associated with locoregional recurrence or RFS. Despite a preponderance of adverse features among the boost cohort, outcomes were similar to those not receiving a boost, suggesting that a boost may mitigate risk of recurrence among patients with high-risk features. Ongoing studies will elucidate the extent to which a tumor bed boost influences disease control rates.

Abstract
Use of selective dry cow antimicrobial therapy requires to precisely differentiate cows with an intramammary infection (IMI) from uninfected cows close to drying-off to enable treatment allocation. Milk somatic cell count (SCC) is an indicator of an inflammatory response in the mammary gland and is usually associated with IMI. However, SCC can also be influenced by cow-level variables such as milk yield, lactation number and stage of lactation. In recent years, predictive algorithms have been developed to differentiate cows with IMI from cows without IMI based on SCC data. The objective of this observational study was to explore the association between SCC and subclinical IMI, taking cognizance of cow-level predictors on Irish seasonal spring calving, pasture-based systems. Additionally, the optimal test-day SCC cut-point (maximized sensitivity and specificity) for IMI diagnosis was determined. A total of 2,074 cows, across 21 spring calving dairy herds with an average monthly milk weighted bulk tank SCC of ≤200,000 cells/mL were enrolled in the study. Quarter-level milk sampling was carried out on all cows in late lactation (interquartile range = 240-261 d in milk) for bacteriological culturing. Bacteriological results were used to define cows with IMI, when ≥1 quarter sample resulted in bacterial growth. Cow-level test-day SCC records were provided by the herd owners. The ability of the average, maximum and last test-day SCC to predict infection were compared using receiver operator curves. Predictive logistic regression models tested included parity (primiparous or multiparous), yield at last test-day and a standardized count of high SCC test-days. In total, 18.7% of cows were classified as having an IMI, with first parity cows having a higher proportion of IMI (29.3%) compared with multiparous cows (16.1%). Staphylococcus aureus accounted for the majority of these infections. The last test-day SCC was the best predictor of infection with the highest area under the curve. The inclusions of parity, yield at last test-day, and a standardized count of high SCC test-days as predictors did not significantly improve the ability of last test-day SCC to predict IMI. The cut-point for last test-day SCC which maximized sensitivity and specificity was 64,975 cells/mL. This study indicates that in Irish seasonal pasture-based dairy herds,with low bulk tank SCC control programs, the last test-day SCC (interquartile range days in milk = 221-240) is the best predictor of IMI in late lactation.

Abstract
BACKGROUND Young age at breast cancer diagnosis is associated with negative prognostic outcomes, and breast cancer in black women often manifests at a young age. This study evaluated the effect of age on breast cancer management and outcomes in black women. METHODS This was a retrospective cohort study of all black women treated for invasive breast cancer between 2005 and 2010 at a specialized tertiary-care cancer centre. Clinical and treatment characteristics were compared by age. Kaplan-Meier methodology was used to estimate overall survival (OS) and disease-free survival (DFS). RESULTS A total of 666 black women were identified. Median BMI was 30 (range 17-56) kg/m2 and median tumour size was 16 (1-155) mm. Most tumours were oestrogen receptor-positive (66·4 per cent). Women were stratified by age: less than 40 years (74, 11·1 per cent) versus 40 years or more (592, 88·9 per cent). Younger women were significantly more likely to have a mastectomy, axillary lymph node dissection and to receive chemotherapy, and were more likely to have lymphovascular invasion and positive lymph nodes, than older women. The 5-year OS rate was 88·0 (95 per cent c.i. 86·0 to 91·0) per cent and the 5-year DFS rate was 82·0 (79·0 to 85·0) per cent. There was no statistically significant difference in OS by age (P = 0·236). Although DFS was inferior in younger women on univariable analysis (71 versus 88 per cent; P < 0·001), no association was found with age on multivariable analysis. CONCLUSION Young black women with breast cancer had more adverse pathological factors, received more aggressive treatment, and had worse DFS on univariable analysis. Young age at diagnosis was, however, not an independent predictor of outcome.

Abstract
The objective of this study was to assess the effect of treating cows with teat sealant only compared with antibiotic plus teat sealant at drying off on weekly somatic cell count, potential intramammary infection, and milk production across the entire subsequent lactation. In 3 research herds in the south of Ireland, cows with SCC that did not exceed 200,000 cells/mL in the previous lactation (LowSCC) were randomly assigned to 1 of 2 treatments at drying off: internal teat sealant alone (ITS) or antibiotic plus teat sealant (AB+ITS). Cows with SCC that exceeded 200,000 cells/mL in the previous lactation were treated with AB+ITS and included in the analyses as a separate group (HighSCC). Weekly individual animal composite SCC records were available for 654 cow lactations and were transformed to somatic cell scores (SCS) for the purpose of analysis. Data were divided into 3 data sets to represent records obtained (1) up to 35 DIM, (2) up to 120 DIM, and (3) across the lactation. Foremilk secretions were taken from all quarters at drying off, at calving, 2 wk after calving, and in mid-lactation and were cultured to detect the presence of bacteria. The LowSCC cows treated with ITS alone had higher daily milk yield (0.67 kg/d) across lactation compared with LowSCC cows treated with AB+ITS. The LowSCC cows treated with ITS alone had higher SCS in early, up to mid, and across lactation compared with LowSCC cows treated with AB+ITS. We detected no difference in weekly SCS of LowSCC cows treated with ITS alone and SCS of HighSCC cows. The least squares means back-transformed SCC across lactation of the LowSCC cows treated with ITS alone, LowSCC cows treated with AB+ITS, and HighSCC cows were 41,523, 34,001, and 38,939 cells/mL respectively. The odds of LowSCC cows treated with ITS alone having bacteria present in their foremilk across lactation was 2.7 (95% confidence interval: 1.91 to 3.85) and 1.6 (1.22 to 2.03) times the odds of LowSCC cows treated with AB+ITS and of HighSCC cows treated with AB+ITS, respectively. In this study, Staphylococcus aureus was the most prevalent pathogen isolated from the population. Recategorizing the threshold for LowSCC cows as ≤150,000 cells/mL or ≤100,000 cells/mL in the previous lactation had no effect on the results. The results indicate that herds with good mastitis control programs may use ITS alone at dry-off in cows with SCC <200,000 cells/mL across lactation with only a small effect on herd SCC.

Abstract
Abstract
Background: LCIS is considered a risk factor for bilateral breast cancer, but the effect of LCIS diagnosed concurrently with DCIS is not known. We sought to compare CBC and ipsilateral breast tumor recurrence (IBTR) rates in women with DCIS with and without synchronous LCIS treated with breast conserving surgery (BCS).
Methods: A prospectively maintained database of DCIS patients undergoing BCS from 2000-2011 was used to identify women with a contralateral breast at risk. Patients with synchronous ipsilateral LCIS found at core needle biopsy or surgical excision were included in the “DCIS + LCIS” group; those with contralateral or bilateral LCIS were excluded. Associations of patient, tumor, and treatment factors with CBC and IBTR were evaluated using logistic regression.
Results: Of the 1888 patients identified, 1475 (78%) had DCIS only and 413 (22%) had DCIS with synchronous LCIS. Median follow-up was 7.5 years (range 0-17 years). 305 patients had a subsequent breast event; 216 IBTR and 89 CBC.
The 5 and 10-year cumulative incidence of IBTR was similar in both groups: 6.3% and 14.4% for DCIS only, compared with 5.9% and 14.0% for DCIS + LCIS (p = 0.94), respectively. The 5 and 10-year cumulative incidence of CBC was significantly greater in the DCIS + LCIS group: 5.7% and 10.0%, compared with 2.4% and 5.0% for DCIS only (p < 0.001).
Table 1 summarizes uni-and multi-variable analyses of risk factors associated with CBC and IBTR among women with DCIS treated with BCS. After adjustment for other factors, CBC risk was more than 2-fold higher in the DCIS + LCIS group compared with the DCIS only group (HR 2.37, 95% CI 1.54-3.65, p < 0.001). There was no difference in IBTR risk based on presence of synchronous LCIS. Younger age and receipt of endocrine therapy were significantly associated with decreased risk of CBC.

Conclusions: LCIS diagnosed concurrently with DCIS is not associated with IBTR, but increases the risk of CBC two-fold. Endocrine therapy should be considered both for the index DCIS and for prevention of subsequent CBC.

Abstract
Selective cytotoxicity to cancer cells without compromising their normal counterparts pose a huge challenge for traditional drug design. Here we developed a tumor antigen targeted delivery of immunonanoparticle carrying a novel non-immunosuppressive FTY720 derivative OSU-2S with potent cytotoxicity against leukemic B cells. OSU-2S induces activation of protein phosphatase 2A, phosphorylation and nuclear translocation of SHP1S591 and deregulation of multiple cellular processes in chronic lymphocytic leukemia (CLL) resulting in potent cytotoxicity. To preclude OSU-2S mediated effects on these ubiquitous phosphatases in unintended cells and avoid potential adverse effects we developed a OSU-2S targeted delivery immunonanoparticles (2A2-OSU-2S-ILP), that mediated selective cytotoxicity of CLL but not normal B cells through targeting receptor tyrosine kinase ROR1 expressed in leukemic but not normal B cells. Developing a novel spontaneous CLL mouse model expressing human ROR1 (hROR1) in all leukemic B cells, we demonstrate the therapeutic benefit of enhanced survival with 2A2-OSU-2S-ILP in-vivo. The newly developed non-immunosuppressive OSU-2S, its delivery using human CLL directed immunonanoparticles and the novel transgenic mouse model of CLL that expresses hROR1 exclusively in leukemic B cell surface are highly innovative and can be applied to CLL and other ROR1+ malignancies including mantle cell lymphoma and acute lymphoblastic leukemia.

Abstract
Rapid and accurate identification of mastitis pathogens is important for disease control. Bacterial culture and isolate identification is considered the gold standard in mastitis diagnosis but is time consuming and results in many culture-negative samples. Identification of mastitis pathogens by PCR has been proposed as a fast and sensitive alternative to bacterial culture. The results of bacterial culture and PCR for the identification of the aetiological agent of clinical mastitis were compared. The pathogen identified by traditional culture methods was also detected by PCR in 98 per cent of cases indicating good agreement between the positive results of bacterial culture and PCR. A mastitis pathogen could not be recovered from approximately 30 per cent of samples by bacterial culture, however, an aetiological agent was identified by PCR in 79 per cent of these samples. Therefore, a mastitis pathogen was detected in significantly more milk samples by PCR than by bacterial culture (92 per cent and 70 per cent, respectively) although the clinical relevance of PCR-positive culture-negative results remains controversial. A mixed infection of two or more mastitis pathogens was also detected more commonly by PCR. Culture-negative samples due to undetected Staphylococcus aureus infections were rare. The use of PCR technology may assist in rapid mastitis diagnosis, however, accurate interpretation of PCR results in the absence of bacterial culture remains problematic.

Abstract
Effective mastitis control requires knowledge of the predominant pathogen challenges on the farm. In order to quantify this challenge, the aetiological agents associated with clinical mastitis in 30 milk-recording dairy herds in Ireland over a complete lactation were investigated. Standard bacteriology was performed on 630 pretreatment quarter milk samples, of which 56 per cent were culture-positive, 42 per cent culture-negative and 2 per cent contaminated. Two micro-organisms were isolated from almost 5 per cent of the culture-positive samples. The bacteria isolated were Staphylococcus aureus (23 per cent), Streptococcus uberis (17 per cent), Escherichia coli (9 per cent), Streptococcus species (6 per cent), coagulase-negative Staphylococci (4 per cent) and other species (1 per cent). A wide variety of bacterial species were associated with clinical mastitis, with S aureus the most prevalent pathogen overall, followed by S uberis. However, the bacterial challenges varied widely from farm to farm. In comparison with previous reports, in the present study, the contagious pathogens S aureus and Streptococcus agalactiae were less commonly associated with clinical mastitis, whereas, the environmental pathogens S uberis and E coli were found more commonly associated with clinical mastitis. While S aureus remains the pathogen most commonly associated with intramammary infection in these herds, environmental pathogens, such as S uberis and E coli also present a considerable challenge.

Abstract
Positron emission tomography/computed tomography (PET/CT)-positive findings before autologous SCT (auto-SCT) are associated with inferior PFS and OS in patients with relapsed Hodgkin's and diffuse large B-cell lymphoma. We classified pre-transplant PET/CT performed before auto-SCT as positive or negative to evaluate the impact of pre-transplant PET/CT in mantle cell lymphoma (MCL). In 29 patients, 17 were PET/CT(-) and 12 were PET/CT(+). PET/CT(+) patients were younger (P=0.04), had lower MCL International Prognostic Index (MIPI, P=0.04) scores, but increased bulky adenopathy >5 cm (45% vs 13%, P=0.09). With a median follow-up of 27 months (range: 5-55 months), 7 patients relapsed (4 in the PET/CT(-) group and 3 in the PET/CT(+) group) with 2 deaths in the PET/CT(+) group without a documented relapse. The estimated 2-year PFS was 64% (95% confidence interval (CI): 0.30-0.85) vs 87% (95% CI: 0.57-0.97) in PET/CT(+) and PET/CT(-) patients, respectively (P=0.054). OS was significantly decreased in PET/CT(+) patients (P=0.007), with 2-year estimates of 60% (95% CI: 0.23-0.84) vs 100% in PET/CT(-) patients. A positive pre-transplant PET/CT is associated with a poor prognosis in patients with MCL. Additional factors may impact the prognostic value of PET/CT, as several PET/CT(+) patients remain in remission.

Abstract
OBJECTIVE The aim of this study was to inform best evidence-based practice by collating and disseminating the experiences of members of the International Pediatric Peritoneal Dialysis Network with children having concurrent ventriculoperitoneal shunts (VPS) and peritoneal dialysis catheters (PDC). METHODS An online questionnaire was created and distributed to all 135 centers participating in the International Pediatric Peritoneal Dialysis Network; the overall response rate was 56 %. RESULTS A total of 18 patients with a concurrent VPS and PDC were reported. The children were 0-12 (mean 6.8) years old at the time of placement of the second indwelling device (PDC or VPS). In 15 cases, the PDC was inserted post-VPS. On average, the two catheters were present concurrently for 23 (range 1-60) months. There were 20 episodes of peritonitis observed in 11 of the 18 patients during a period of 392 months at risk, which is a peritonitis rate of 1/19.6 months. Only one patient developed both a VPS infection and an episode of peritonitis, and these events were temporally unrelated. No episodes of an ascending shunt infection or meningitis occurred in association with any episode of peritonitis, and no other complications of catheter dysfunction were described. CONCLUSIONS The rate of peritonitis, the absence of any documented ascending or descending infections and the lack of catheter dysfunction during the period of observation suggests that the presence of, or need for, a VPS should not preclude PD as a safe option for children requiring renal replacement therapy.

Abstract
The innate immune response of milk somatic cells in cows to Streptococcus dysgalactiae ssp. dysgalactiae was investigated by deliberate intramammary challenge. Cows were challenged with 2,500 colony-forming units of Strep. dysgalactiae DPC 5435, previously isolated from a clinical mastitis case. Eight of the 9 cows treated showed clinical signs of mastitis (swollen udders, increased somatic cell score, and clotted milk) within 1 wk of challenge. Messenger RNA levels of IL-1β and toll-like receptor 4 (TLR4) in milk somatic cells increased approximately 40 fold within 48 h of infusion, whereas tumor necrosis factor α increased 16 fold within the same time frame. Interestingly, cows homozygous for the G allele of the C-X-C chemokine receptor type 1 (CXCR1)-777 polymorphism had higher IL-8 and CXCR1 transcript abundance at 24h postinfusion compared with cows homozygous for the C allele. The difference in expression of these genes at this critical time point may influence the severity of disease within different genotypes.

Abstract
Symptoms of sugarcane orange rust were observed on July 17, 2008 on sugarcane cvs. Mex 57-1285, Mex 61-230, and Co 301 (a clone received in Mexico in 1953) at the Centro de Investigación y Desarrollo de la Caña de Azúcar en Tuxtla Chico, Chiapas, Mexico. In El Salvador, from August 2008 through January 2009, rust symptoms were observed on cv. CP 72-2086 (previously resistant to brown rust caused by Puccinia melanocephala Syd. & P. Syd.) in 117 dispersed sugarcane-production fields in various localities of El Salvador. Likewise, rust symptoms were first observed on sugarcane cv. SP 74-8355 (more than 25% severity and considered resistant to brown rust) at Natá, Coclé Province in Panama from January to February 2008. Dried herbarium leaf samples of sugarcane rust-infected leaves collected in El Salvador and Mexico were sent to the ARS, USDA Systematic Mycology and Microbiology Laboratory in Beltsville MD for identification. Panamanian samples were collected similarly and analyzed at the CALESA Biotechnology Laboratory. Morphological features of uredinial lesions and urediniospores were distinct from those of P. melanocephala and consistent with P. kuehnii E. J. Butler observed previously on specimens from Florida, Guatemala, Costa Rica, and Nicaragua (1-3). Analysis of the ITS1, 5.8S, and ITS2 and 28S large subunit rDNA sequences of the rust on infected cvs. Mex 57-1285, Mex 61-230, and Co 301 (BPI 878930, 879139, and 879140; GenBank Accession Nos. GO283006, GO283004, and GO283005, respectively) from Mexico and cv. CP 72-2086 from three locations in El Salvador (BPI 879135, 879136, and 879137; GenBank Accession Nos. GO283009, GO283007, and GO283008, respectively) all confirmed the identification of P. kuehnii. Similar analysis of the ITS1, 5.8S, and ITS2 rDNA sequence for the rust infecting cv. SP 74-8355 (GenBank Accession No. GO281584) confirmed the identification of P. kuehnii in Panama. To our knowledge, this is the first report of P. kuehnii causing orange rust disease of sugarcane in El Salvador, Mexico, and Panama. These findings also confirm the wider distribution of orange rust in the Western Hemisphere. References: (1) E. Chavarria et al. Plant Dis. 93:425, 2009. (2) J. C. Comstock et al.

Abstract
A study was carried out to investigate the effect of six pre-milking teat preparation procedures on lowering the staphylococal, streptococcal and coliform microbial count on teat skin prior to cluster application. The teat preparations included 'Iodine', 'Chlorhexidine' teat foam, 'Washing and drying' with paper, 'No preparation', 'Chlorine' teat foam, and disinfectant 'Wipes'. Teat preparations were applied for five days to 10 cows for each treatment during two herd management periods (indoors and outdoors). Teats were swabbed on day four and five before teat preparation and repeated after teat preparation. The swabs were plated on three selective agars: Baird Parker (Staphylococcus spp.), Edwards (Streptococcus spp.), and MacConkey (coliform). Following incubation, microbial counts for each pathogen type were manually counted and assigned to one of six categories depending on the microbial counts measured. The results were analysed by logistic regression using SAS 28. The main analysis was conducted on binary improvement scores for the swabbing outcomes. There were no differences for staphylococcal, streptococcal and coliform bacterial counts between treatments, measured 'before' teat preparation. Treatments containing 'Chlorhexidine' teat foam (OR = 4.46) and 'Wipes' (OR = 4.46) resulted in a significant reduction (P < 0.01) in the staphylococcal count on teats compared to 'Washing and drying' or 'No preparation'. 'Chlorine' teat foam (OR = 3.45) and 'Wipes' (3.45) had the highest probability (P < 0.01) of reducing streptococcal counts compared to 'Washing and drying' or 'No preparation'. There was no statistical difference between any of the disinfectant treatments applied in reducing coliforms. Thus, the use of some disinfectant products for pre-milking teat preparation can have beneficial effects on reducing the levels of staphylococcal and streptococcal pathogens on teat skin.

Abstract
e16088 Background: Potential antagonism of clinical response to cancer treatment by naturopathic/nutritional supplements (NNS) with anti-oxidant activity has been suggested. This study assessed effects of NNS on tumor response to radiation therapy (RT) in prostate cancer patients (PCpts). Methods: Of 134 RT-treated PCpts with localized tumors, 69 received NNS (+NNS; median age=62.0 yrs) and 65 did not (-NNS; median age=61.5 yrs). Based on pre-RT PSA, 52low (4–10 ng); 13 intermediate (10–20 ng); and 4 high risk (> 20 ng) PCpts were +NNS and 50, 10, and 5 low, intermediate & high risk PCpts were -NNS. Tumor stages for +NNS were T1c (39%); T2a (44%); T2b (10%); T2c (5%) with 1 T3b tumor and were T1b (3%); T1c (46%); T2a (32%); T2b (12%); and, T2c (5%) with 1 T3a tumor for -NNS cohorts. RT consisted of external beam therapy (4500–5000 cGy) + HDR brachytherapy (600–650 cGy/fraction x 2–3 fractions) administered over 6–8 weeks. NNS regimens (range 1–7 antioxidants) included Green Tea Extract, Melatonin, high-potency multivitamins, vitamin C, and vitamin E. All pts were monitored ≥ 24 months post RT. Hormonal therapy (HT; oral bicalutamide (50 mg/day) ±leuprolide depot (22.5 mg IM q 3 months) as neoadjuvant or adjuvant HT was given to 39 (57%) and 38 (58%) PCpts in the +NNS and -NNS cohorts respectively. Results: For the +NNS cohort that did not receive HT, PSA levels were 5.05; 0.285; and 0.356 ng at pretreatment, nadir and ≥ 24 months followup respectively with PSA nadir at 27 months and median followup of 36 months. The corresponding values for the -NNS cohort were 5.6, 0.54, and 0.585 ng with PSA nadir at 25 months and median followup of 29.6 months. Differences were not statistically significant. For the +NNS cohort that did receive HT, PSA levels were 6.8, 0.03 and 0.12 ng at pretreatment, nadir and ≥ 24 months followup with median time to nadir = 4.3 months and median followup = 29.2 months. Corresponding values for -NNS cohort were 6.9, 0.03, and 0.11 with median time to nadir = 3.6 months and median followup = 30.5 months. Differences were also not statistically significant. Conclusions: This study shows that NNS with antioxidant activity do not interfere with clinical response to RT ± HT as definitive treatment for limited stage prostate cancer.

Abstract
e20500 Background: Despite recent therapeutic advances, PNA remains a significant source of morbidity and mortality among CLL pts. We determined population-level estimates for the incidence and outcome of PNA hospitalizations. We further investigated secular trends in care by comparing cohorts before (1994) and after (2004) the widespread use of multiagent chemoimmunotherapy. Methods: Using data from the U.S. Nationwide Inpatient Sample and ICD-9CM diagnosis codes, we identified all non-governmental hospitalizations of CLL pts for a primary dx of PNA in calendar years 1994 and 2004. Admissions were described by pt demographics (age, gender, race) and comorbidity (Charlson index, presence of chronic lung disease). Ten-year prevalence estimates for CLL were obtained from NCI SEER data and used as denominators in incidence calculations. Outcomes studied included need for intubation, in-hospital mortality, and length of stay (LOS). All analyses were sample weighted. Estimates and 95% confidence limits are reported. Results: PNA was the primary dx for 7316 (13.1%) and 7651 (11.2%) CLL pt admissions in 1994 and 2004, respectively. Incidence of PNA admission was similar in 1994 (140/per 1000 pts, 95%CI 130–151) and 2004 (129/per 1000 pts, 95%CI 119–138). CLL pts admitted in 2004 were older (75.7 v. 74.2 years, p<0.001) and more likely to have at least one Charlson comorbidity (67.6% v. 56.2%, p<0.001) or comorbid chronic lung disease (40.6% v. 28.3%, p<0.001) than pts in 1994. Intubation was rare in both cohorts (<1%) and did not significantly differ by year, but in-hospital mortality was significantly higher in 2004 (11.3% v. 8.2%, p=0.005). However, LOS decreased significantly between 1994 and 2004 (9.2 v. 6.4 days, p<0.001). Conclusions: PNA hospitalization rates for CLL pts have not significantly increased over the last decade despite more aggressive therapies, likely secondary to improved supportive care. However, CLL pts hospitalized for PNA are now older, increasingly likely to suffer from chronic medical illness, and significantly more likely to die while in hospital. Therapuetic strategies targeting older pts with significant comorbidities are needed. No significant financial relationships to disclose.

Abstract
7591 Background: NSCLC patients (pts) with clinically significant endobronchial obstruction have a poor prognosis and quality of life in both locally advanced and metastatic stages of disease. Radiation therapy (RTx) in conjunction with chemotherapy (CTx) improves survival compared to either modality alone but produces greater toxicity and morbidity. Significant clinical benefit with respect to disease management and quality of life could be realized with improved methods for controlling obstructing endobronchial lesions. The hypothesis for this study is that optimal clinical control of endobronchial lesions can be achieved by intratumoral injection of a drug with both clinical activity against NSCLC and synergy with RTx. Cisplatin (CPt), an active agent in NSCLC and a known radiosensitizer is an ideal drug for this objective. Thus, the goal of this exploratory study was to determine the clinical efficacy and tolerance to intratumoral CPt injection in combination with HDR brachytherapy (BTx) in NSCLC patients with obstructing endobronchial lesions. Methods: NSCLC pts (n=16) with > 75% endoluminal obstruction of a main or lobar airway were evaluated. Intratumoral CTx consisted of CPt (1 mg/ml; 0.5–2.0 ml/session) injected into the entire visible tumor through a flexible 21 gauge needle through the bronchoscope. BTx was given as 500 cGy/session at one cm diameter for 4 sessions concomitant with CTx. Results: All pts completed the entire 4 sessions of planned local therapy. There was complete resolution of injected lesions in 14/16 pts confirmed bronchoscopically and cytologically. In the other 2 pts, necrotic tissue occupying < 10 and 20% of the airway, cytologically negative for tumor was seen. There were no adverse events or complications related to bronchoscopy or local CTx. Conclusions: The results of this study demonstrate that intratumoral administration of CPt, as an adjunct to endobronchial BTx for the management of endobronchial obstructing lesions in patients with NSCLC is safe and effective. This approach offers the possibility of superior local tumor control while reducing toxicity to normal lung and esophagus as compared to conventional external beam radiation therapy modalities. Further studies evaluating the impact of this approach on survival and quality of life are warranted. No significant financial relationships to disclose.

Abstract
This study performed a systems analysis of the process by which patients under the care of a specialist palliative home care obtained medications, and highlighted factors that delay this process. Systems analysis is the science dealing with analysis of complex, large-scale systems and the interactions within those systems. This study used a mixed-methods approach of questionnaires of general practitioners, pharmacists and patients, and a prospective observational study of delays experienced by patients referred to the home care team over a three-month period. This study found the main factors causing delay to be: medications not being in stock in pharmacies, medications not being available on state reimbursed schemes and inability of patients and carers to courier medications.

Abstract
15585 Background. CAM therapy in pts receiving RT has been questioned due to possible interference with oxidative mechanisms aimed at killing tumor cells. We addressed this controversy by analyzing tumor response, control and recurrence in PCpts treated with RT + CAM. Methods. The population consisted of 125 RT-treated PCpts with localized tumors: CAM cohort (n=69; median age=62.5 yrs; range=46–81); nonCAM cohort (n=56; median age=61.0 yrs; range=48–80). For the CAM cohort, 41%, 42%, 9% and 7% had T1c, T2a, T2b and T2c tumors respectively with 1 T3b tumor; for the nonCAM cohort, 39%, 38%, 14% and 7% had T1c, T2a, T2b and T2c tumors respectively with 1 T3a tumor. RT consisted of external beam therapy (4500–5000 cGy) in conjunction with high dose rate brachytherapy (600- 650 cGy/fraction x 2–3 fractions) administered over 6–8 weeks; this occurred for 65/69 CAM and 52/56 nonCAM pts. The remaining pts received either HDR monotherapy, tomotherapy, or IMRT + tomotherapy. In addition, 5/69 CAM and 2/56 nonCAM pts received hormonal therapy. CAM regimens included at least one antioxidant (range=1–7) including Green Tea Extract; Melatonin; and high-potency multivitamins. All pts were monitored ≥ 24 months post radiation therapy. Results. In the CAM cohort, median pretreatment PSA was 5.95ng; nadir PSA was 0.08ng; and last PSA was 0.18ng with median followup of 28.96 (range=24–46) months; 3 biochemical failures were seen at 6, 10 and 12 months. In the nonCAM cohort, median pretreatment PSA was 6.4ng; nadir PSA was 0.06ng; and last PSA was 0.166ng with median followup of 28.26 (range=24–43) months; 2 biochemical failures at 13 and 28 months with 1 death at 37 months were seen. Conclusion. Concomitant CAM treatment does not effect RT-mediated tumor response, control or recurrence rates in PCpts with localized disease. Neither the magnitude of the response or its durability for at least 2 years are negatively affected by CAM-based antioxidant supplements designed to improve patient tolerance and quality of life. Investigations in well-defined populations receiving consistent CAM regimens offer the opportunity to elucidate positive benefits for patient management. No significant financial relationships to disclose.

Abstract
OBJECTIVE To characterize deficits in nonverbal recognition memory and functional brain changes associated with these deficits in Alzheimer disease (AD). METHODS Using O-15 PET, we studied 11 patients with AD and 17 cognitively intact elders during the combined encoding and retrieval periods of a nonverbal recognition task. Both task conditions involved recognition of line drawings of abstract shapes. In both conditions, subjects were first presented a list of shapes as study items, and then a list as test items, containing items from the study list and foils. In the titrated demand condition, the shape study list size (SLS) was adjusted prior to imaging so that each subject performed at approximately 75% recognition accuracy; difficulty during PET scanning in this condition was approximately matched across subjects. A control task was used in which SLS = 1 shape. RESULTS During performance of the titrated demand condition, SLS averaged 4.55 (+/-1.86) shapes for patients with AD and 7.53 (+/-4.81) for healthy elderly subjects (p = 0.031). However, both groups of subjects were closely matched on performance in the titrated demand condition during PET scanning with 72.17% (+/-7.98%) correct for patients with AD and 72.25% (+/-7.03%) for elders (p = 0.979). PET results demonstrated that patients with AD showed greater mean differences between the titrated demand condition and control in areas including the left fusiform and inferior frontal regions (Brodmann areas 19 and 45). CONCLUSIONS Relative fusiform and inferior frontal differences may reflect the Alzheimer disease (AD) patients' compensatory engagement of alternate brain regions. The strategy used by patients with AD is likely to be a general mechanism of compensation, rather than task-specific.

Abstract
BACKGROUND In recent years, the discipline of paediatric palliative care has emerged in response to the awareness of the distinct needs of dying children. To date, in Ireland there is no paediatrician trained in palliative medicine, and specialist paediatric palliative care is generally delivered by adult trained teams. AIMS We wished to examine the experience of an adult palliative care service providing palliative care to children. METHODS The study entailed three stages: (1) a retrospective chart review of all children referred to the service; (2) a questionnaire survey; and (3) a focus group to explore the views of staff in caring for children. RESULTS The main themes highlighted were staff competence, staff stress, uncertainty of prognosis, resource implications and co-operation with other teams. CONCLUSION This study highlights some of the challenges for an adult palliative care team providing paediatric palliative care. Many skills developed for adult patients can be used in paediatric palliative care. Adult palliative care teams and paediatric teams have complementary skills. The challenge is to integrate services to meet the needs of terminally ill children.

Abstract
AIMS The aim of this study was to isolate and characterize bacteriophages against bovine Staphylococcus aureus associated with mastitis. METHODS AND RESULTS We describe the isolation of two anti-staphylococcal phages namely DW2 and CS1 from farmyard slurry. Both phages were characterized by electron microscopy and restriction analysis and shown to belong to the Siphoviridae family. CS1 and DW2 were lytic for representatives of all three clonal groups of Irish mastitis-associated staphylococci. These phages were compared with the previously characterized Myoviridae phage K. Infusion of a cocktail of all three phages at 10(8) PFU ml(-1) into live cow teats resulted in no detectable increase in somatic cell counts in milks indicating that the phages did not irritate the animal. CONCLUSION Two new anti-staphylococcal phages CS1 and DW2 were isolated and characterized and tested for immunogenicity in animal teats. SIGNIFICANCE AND IMPACT OF THE STUDY The phages isolated in this study are active against pathogenic S. aureus and may be incorporated into teat-dips or teat-washes as a non-antibiotic prophylaxis against staphylococcal bovine mastitis.

Abstract
A comprehensive male linkage map was generated by adding 359 new, informative microsatellites to the International Equine Gene Map half-sibling reference families and by combining genotype data from three independent mapping resources: a full sibling family created at the Animal Health Trust in Newmarket, United Kingdom, eight half-sibling families from Sweden and two half-sibling families from the University of California, Davis. Because the combined data were derived primarily from half-sibling families, only autosomal markers were analyzed. The map was constructed from a total of 766 markers distributed on the 31 equine chromosomes. It has a higher marker density than that of previously reported maps, with 626 markers linearly ordered and 140 other markers assigned to a chromosomal region. Fifty-nine markers (7%) failed to meet the criteria for statistical evidence of linkage and remain unassigned. The map spans 3,740 cM with an average distance of 6.3 cM between markers. Fifty-five percent of the intervals are < or = 5 cM and only 3% > or = 20 cM. The present map demonstrates the cohesiveness of the different data sets and provides a single resource for genome scan analyses and integration with the radiation hybrid map.

Abstract
BACKGROUND Associations between the APOE genotype and various medical conditions have been documented at a very young age. The association between the APOE genotype and cognitive performance varies at different ages. APOE related changes in brain activation have been recently reported for middle aged and elderly subjects. OBJECTIVE To explore APOE related alterations during cognitive activation in a population of young adults. METHODS Using H2(15)O positron emission tomography (PET), imaging was carried out in 20 healthy young adults (age 19 to 28 years; four epsilon4 carriers and 16 non-epsilon4 carriers) during a non-verbal memory task. Voxel-wise multiple regression analyses were undertaken, with the activation difference PET counts as the dependent variable and the APOE genotype as the independent variable. RESULTS Brain regions were identified where epsilon4 carriers showed significantly lower or higher activation than non-carriers. CONCLUSIONS The results suggest that APOE dependent modulation of cerebral flow may be present even at a young age. This may reflect an APOE related physiological heterogeneity which may or may not predispose to brain disease in the ensuing decades or, less likely, the effect of very early Alzheimer's disease related pathological changes.
