Abstract
The JAVELIN Bladder 100 phase III trial led to the incorporation of avelumab first-line (1L) maintenance treatment into international guidelines as a standard of care for patients with advanced urothelial carcinoma (UC) without progression after 1L platinum-based chemotherapy. JAVELIN Bladder 100 showed that avelumab 1L maintenance significantly prolonged overall survival (OS) and progression-free survival in this population compared with a 'watch-and-wait' approach. The aim of this manuscript is to review clinical studies of avelumab 1L maintenance in patients with advanced UC, including long-term efficacy and safety data from JAVELIN Bladder 100, subgroup analyses in clinically relevant subpopulations, and 'real-world' data obtained outside of clinical trials, providing a comprehensive resource to support patient management. Extended follow-up from JAVELIN Bladder 100 has shown that avelumab provides a long-term efficacy benefit, with a median OS of 23.8 months measured from start of maintenance treatment, and 29.7 months measured from start of 1L chemotherapy. Longer OS was observed across subgroups, including patients who received 1L cisplatin + gemcitabine, patients who received four or six cycles of 1L chemotherapy, and patients with complete response, partial response, or stable disease as best response to 1L induction chemotherapy. No new safety signals were seen in patients who received ≥1 year of avelumab treatment, and toxicity was similar in those who had received cisplatin or carboplatin with gemcitabine. Other clinical datasets, including noninterventional studies conducted in Europe, USA, and Asia, have confirmed the efficacy of avelumab 1L maintenance. Potential subsequent treatment options after avelumab maintenance include antibody-drug conjugates (enfortumab vedotin or sacituzumab govitecan), erdafitinib in biomarker-selected patients, platinum rechallenge in suitable patients, nonplatinum chemotherapy, and clinical trial participation; however, evidence to determine optimal treatment sequences is needed. Ongoing trials of avelumab-based combination regimens as maintenance treatment have the potential to evolve the treatment landscape for patients with advanced UC.

Abstract
BACKGROUND Patients with antibody deficiency respond poorly to coronavirus disease 2019 (COVID-19) vaccination and are at risk of severe or prolonged infection. They are given long-term immunoglobulin replacement therapy (IRT) prepared from healthy donor plasma to confer passive immunity against infection. Following widespread COVID-19 vaccination alongside natural exposure, we hypothesized that immunoglobulin preparations will now contain neutralizing severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike antibodies, which confer protection against COVID-19 disease and may help to treat chronic infection. METHODS We evaluated anti-SARS-CoV-2 spike antibody in a cohort of patients before and after immunoglobulin infusion. Neutralizing capacity of patient samples and immunoglobulin products was assessed using in vitro pseudovirus and live-virus neutralization assays, the latter investigating multiple batches against current circulating Omicron variants. We describe the clinical course of 9 patients started on IRT during treatment of COVID-19. RESULTS In 35 individuals with antibody deficiency established on IRT, median anti-spike antibody titer increased from 2123 to 10 600 U/mL postinfusion, with corresponding increase in pseudovirus neutralization titers to levels comparable to healthy donors. Testing immunoglobulin products directly in the live-virus assay confirmed neutralization, including of BQ1.1 and XBB variants, but with variation between immunoglobulin products and batches.Initiation of IRT alongside remdesivir in patients with antibody deficiency and prolonged COVID-19 infection (median 189 days, maximum >900 days with an ancestral viral strain) resulted in clearance of SARS-CoV-2 at a median of 20 days. CONCLUSIONS Immunoglobulin preparations now contain neutralizing anti-SARS-CoV-2 antibodies that are transmitted to patients and help to treat COVID-19 in individuals with failure of humoral immunity.

Abstract
The COVID-19 pandemic and associated 'lockdowns' profoundly impacted people's lives in 2020-2021 and beyond. This study sought to understand unique person-centred insights into health and wellbeing during the restrictive measures in the United Kingdom and to enable us to remember and give testimony to these lived experiences. Using photo-methods, participants from a larger cohort study which tracked people's behaviours during the pandemic were invited to share photographs and short text to visually illustrate their ephemeral and unique COVID-19 experiences. In total 197 participants shared 398 photographs. Using a critical realist approach in our design and analysis, we sought to gain an alternative viewpoint on what 'lockdown' and the pandemic meant. Our major findings revealed starkly contrasting experiences illustrated in our two major themes. Firstly loss, including ambiguous losses and a sense of loss, loss of freedoms and death. Secondly, salutogenesis (what makes us well) whereby participants were able to draw on assets which helped to keep them well by maintaining social connection, 'making the best of it', reconnecting with nature and appreciating the outdoors, creativity for pleasure and faith. Our findings illuminate widely differing experiences and indicate the powerful effect of assets that were perceived by our participants to protect their wellbeing. Understanding differential vulnerability will be essential going forward to target resources appropriately to those who have the least control over their lives, those with the greatest vulnerabilities and least assets which in turn could support a self-perpetuating recovery.

Abstract
AIMS (1) To explore how social prescribing referrals impact experiences of existing members of a voluntary and community-based organisation and (2) to describe the processes and relationships associated with joining community and voluntary organisations. METHODS Online survey and qualitative interviews with members of Men's Sheds, a global volunteer-led initiative to address loneliness and social isolation in men. 93 self-selecting Shed members (average age 67 years, 93% male) from across England and Scotland took part in the survey about demographics, joining the Shed, and free-text questions about experiences in the Shed. From the survey participants, 21 Shed members were purposively sampled and interviewed to explore the impact of social prescribing and referrals on the Sheds. RESULTS Participating in the Men's Shed was often associated with a significant change in personal circumstances, and Sheds provided a unique social support space, particularly valuable for men. Key factors around experiences of social prescribing and referral mechanisms were identified. We developed three themes: the experience of joining a Shed, success factors and risks of social prescribing, and 'we care but we're not carers'. CONCLUSIONS The results show that Men's Sheds are a caring organisation, but their members are not trained as professional carers, and men come to the Shed for their own personal reasons. They are concerned about the potential additional responsibilities associated with formal referrals. They encourage the development of relationships and local-level understanding of the essence of Sheds to enable social prescribing. As models of social prescribing grow nationally and internationally, collaboratively working with voluntary and community organisations to develop a mutually beneficial approach is essential for the effectiveness and sustainability of social prescribing in community health.

Abstract
AIMS Foodbanks provide emergency food provision. This need can be triggered by a change in circumstance or a crisis. Failures in the social security safety net are the most significant driver for hunger in the UK. There is some evidence that an advisory service which runs alongside a foodbank is more effective in reducing emergency provision and the duration and severity of hunger. The 'Making a Difference' project at an English foodbank is a pilot scheme aiming to increase financial resilience in their service users. From summer 2022, they introduced new advice worker roles, in partnership with Shelter [Housing advice] and Citizen's Advice [General, debt and benefits advice], aiming to pre-empt the need for foodbank use, to triage the financial needs of service users and refer appropriately to reduce repeat visits to the foodbank. METHODS This qualitative study involved in-depth interviews with four staff and four volunteers to evaluate barriers, facilitators and potential friction points in referrals and partnership working. FINDINGS Our data were analysed thematically into four themes: Holistic needs assessment; Reaching seldom heard communities; Empowerment; The needs of staff and volunteers. Two case studies illustrate the complexity of people's needs. CONCLUSION A financial inclusion service operating within foodbanks giving housing, debt and benefits advice shows some promise in reaching people in crisis at the point of need. Based within the heart of a community, it appears to meet the complex needs of very vulnerable people who may have found mainstream support services inaccessible. This asset-based approach with the foodbank as a trusted provider enabled joined up, compassionate, holistic, and person-centred advice quickly cutting across multiple agencies, reaching underserved and socially excluded clients. We suggest that supportive services are needed for volunteers and staff who are vulnerable to vicarious trauma from listening and supporting people in crisis.

Abstract
Their unique hydrological and climatic conditions render surface water systems in the southern Canadian Prairies at an elevated risk from exposure to contaminants released from municipal wastewater effluents (MWWEs). The aim of this study was to characterize the potential health effects and their underlying molecular mechanisms in populations of fathead minnow (Pimephales promelas; FHM) in Wascana Creek, an effluent dominated stream in Southern Saskatchewan, Canada. Studies were conducted during the spawning season in 2014 and 2015 to assess responses in terms of overall health, reproductive functions, plasma sex steroid hormone levels, and expression of selected genes along the hypothalamus-pituitary-gonadal axis. FHM downstream of the effluent fallout had lower gonadosomatic indices and significantly greater hepatosomatic indices compared to upstream populations. In both male and female FHMs, significantly greater occurrence and severity of gonadal degradation and delayed maturation were observed in downstream fish compared to upstream fish. Downstream males also displayed lower scores of secondary sexual characteristics and a decreasing trend in plasma 11-ketotestosterone levels. Interestingly, no indications of exposure to estrogenic compounds, such as occurrence of testicular oocytes were observed, which was in accordance with the lack of presence of key biomarkers of estrogenic exposure, such as induction of vitellogenin. In general, expression of the majority of transcripts measured in FHMs downstream of the effluent fallout was significantly downregulated, which supports observations of the general deterioration of the health and reproductive status of these fish. Chemical analysis indicated that 10 pharmaceuticals and personal care products (PPCPs) were present at the downstream site, some at sufficiently great concentrations that may present a risk to aquatic organisms. With continuous exposure to a diverse number of stressors including high nutrient and ammonia levels, the presence of a variety of PPCPs and other contaminants, Wascana Creek should be considered as an ecosystem at risk.

Abstract
BACKGROUND Hemoglobin C, D Punjab, E or S trait can interfere with hemoglobin A1c (HbA1c) results. We assessed whether they affect results obtained with 15 current assay methods. METHODS Hemoglobin AA (HbAA), HbAC, HbAD Punjab, HbAE and HbAS samples were analyzed on 2 enzymatic, 4 ion-exchange HPLC and 9 immunoassay methods. Trinity Premier Hb9210 boronate affinity HPLC was the comparative method. An overall test of coincidence of least-squared linear regression lines was performed to determine if HbA1c results were statistically significantly different from those of HbAA samples. Clinically significant interference was defined as >6% difference from HbAA at 6 or 9% HbA1c compared to Premier Hb9210 using Deming regression. RESULTS All methods showed statistically significant effects for one or more variants. Clinically significant effects were observed for the Tosoh G11 variant mode (HbAD), Roche b 101 (HbAC and HbAE) and Siemens DCA Vantage (HbAE and HbAS). All other methods (Beckman Coulter B93009 and B00389 on DxC700AU, and Unicel DxC, Ortho Clinical Vitros 5.1, Roche cobas c 513, Siemens Dimension RxL and Vista, and Enzymatic on Advia and Atellica, Tosoh G8 5.24 and 5.28, and GX) showed no clinically significant differences. CONCLUSIONS A few methods showed interference from one or more variants. Laboratories need to be aware of potential HbA1c assay interferences.

Abstract
Every day, emergency departments and acute medical units all over the world receive and assess thousands of patients. Most are stable, but a few require immediate stabilization. To identify these, all patients are routinely triaged and have vital signs measured. Our group has shown that thermographic images of the face can be an alternative method for identifying patients at increased risk of 30-day mortality. In our previous studies, the thermographic images were taken after the patients had been inside for at least 30 minutes. However, to identify patients at risk, the images have to be available as quickly as triage, i.e. at the door when the patient arrives. Therefore, we have performed a small study, with the aim of illustrating the effect of such heat-gradients on thermal images of the face.

Abstract
Primary immunodeficiency (PID) is characterized by recurrent and often life-threatening infections, autoimmunity and cancer, and it poses major diagnostic and therapeutic challenges. Although the most severe forms of PID are identified in early childhood, most patients present in adulthood, typically with no apparent family history and a variable clinical phenotype of widespread immune dysregulation: about 25% of patients have autoimmune disease, allergy is prevalent and up to 10% develop lymphoid malignancies1-3. Consequently, in sporadic (or non-familial) PID genetic diagnosis is difficult and the role of genetics is not well defined. Here we address these challenges by performing whole-genome sequencing in a large PID cohort of 1,318 participants. An analysis of the coding regions of the genome in 886 index cases of PID found that disease-causing mutations in known genes that are implicated in monogenic PID occurred in 10.3% of these patients, and a Bayesian approach (BeviMed4) identified multiple new candidate PID-associated genes, including IVNS1ABP. We also examined the noncoding genome, and found deletions in regulatory regions that contribute to disease causation. In addition, we used a genome-wide association study to identify loci that are associated with PID, and found evidence for the colocalization of-and interplay between-novel high-penetrance monogenic variants and common variants (at the PTPN2 and SOCS1 loci). This begins to explain the contribution of common variants to the variable penetrance and phenotypic complexity that are observed in PID. Thus, using a cohort-based whole-genome-sequencing approach in the diagnosis of PID can increase diagnostic yield and further our understanding of the key pathways that influence immune responsiveness in humans.

Abstract
Abstract
Six foods representative of a wide variety of processed, dried powder processed, and raw food types were analyzed by the Assurance® Gold Salmonella Enzyme Immunoassay (EIA) and AOAC INTERNATIONAL culture method. Paired samples of each food type were simultaneously analyzed; one sample by the Assurance method and one by the AOAC culture method. The results for Assurance method were read visually and instrumentally with a microplate reader. A total of 24 laboratories representing federal government agencies and private industry, in the United States and Canada, participated in this collaborative study. Food types were inoculated with species of Salmonella with the exception of raw ground chicken, which was naturally contaminated. No statistical differences (p < 0.05) were observed between Assurance Gold Salmonella EIA with either visual or instrumental interpretation and the AOAC culture method for any inoculation level of any food type or naturally contaminated food. The Assurance visual and instrumental options of reading sample reactions produced the same results for 1277 of the 1296 sample and controls analyzed.

Abstract
Abstract
Background: In the pivotal BOLERO-2 trial, everolimus (EVE) + exemestane (EXE) more than doubled the median progression-free survival (PFS) vs EXE alone in hormone receptor positive (HR+), human epidermal growth factor-receptor 2-negative (HER2-) advanced breast cancer (ABC) recurring/progressing on/after prior non-steroidal aromatase inhibitors (NSAIs). BRAWO is a German non-interventional study conducted in patients (pts) with HR+, HER2–ABC receiving EVE + EXE, according to Summary of Product Characteristics (SmPC), in routine clinical practice. Here we report the final PFS and safety results.
Methods: This multicenter study documented 2100 pts between October 2012 and December 2017 across 341 sites in Germany. Postmenopausal women with HR+, HER2– ABC with recurrence or progression after a NSAI were included. Primary observation parameters included the evaluation of the effectiveness of EVE + EXE used in routine care for the entire pt group.
Results: In the final analysis, out of the 2100 documented pts, 2074 were included in the full analysis set. The median time since the primary diagnosis was 7.1 years and the median time from first sign of relapse (local recurrence or distant metastases) was 2.1 years. At baseline, 54.1% of pts presented with visceral metastases and 50.1% had an ECOG performance status of 0. Approximately, 63% of pts started with EVE 10 mg (median duration of exposure: 5.1 months; 95% CI, 4.6-5.4), while 34.1% started with EVE 5 mg (median duration of exposure: 4.6 months; 95% CI, 4.1-5.2).
The distribution of treatment lines was as follows: first line, 28.7% (n=595); second line, 31.9% (n=662); third line, 18.1% (n=376); fourth line, 10.7% (n=221) and, fifth line and later, 10.6% (n=220). Treatment was discontinued by 55.7% of pts (n=1170) due to progressive disease and 26% of pts (n=546) due to adverse events. The Kaplan-Meier estimate of the median PFS was 6.6 months (95% CI, 6.2-7.0). The best overall responses, based on clinical routine, were complete response, 0.8% (n=17), partial response, 7.4% (n=150), and stable disease, 41.3% (n=842). The general safety profile was consistent with the previously reported safety findings. The most common adverse events were stomatitis (any grade: 42.6%, grade 3: 3.8%, grade 4: <0.1%) and fatigue (any grade: 19.8%, grade 3: 1.5%).
Conclusions: Data from BRAWO support EVE + EXE as a suitable treatment option with a reasonable safety profile for HR+, HER2− ABC recurring or progressing on/after prior NSAIs.

Abstract
BACKGROUND Hemoglobin C, D Punjab, E or S trait can interfere with hemoglobin A1c (HbA1c) results. We assessed whether they affect results obtained with 12 current assay methods. METHODS Hemoglobin AA (HbAA), HbAC, HbAD Punjab, HbAE and HbAS samples were analyzed on one enzymatic, nine ion-exchange HPLC and two Capillary Electrophoresis methods. Trinity ultra(2) boronate affinity HPLC was the comparative method. An overall test of coincidence of least-squared linear regression lines was performed to determine if HbA1c results were statistically significantly different from those of HbAA samples. Clinically significant interference was defined as >7% difference from HbAA at 6 or 9% HbA1c compared to ultra(2) using Deming regression. RESULTS All methods showed statistically significant effects for one or more variants. Clinically significant effects were observed for the Tosoh G8 variant mode and GX (all variants), GX V1.22 (all but HbAE) and G11 variant mode (HbAC). All other methods (Abbott Architect c Enzymatic, Bio-Rad D-100, Variant II NU and Variant II Turbo 2.0, Menarini HA-8180T thalassemia mode and HA-8180V variant mode, Sebia Capillarys 2 and Capillarys 3) showed no clinically significant differences. CONCLUSIONS Several methods showed clinically significant interference with HbA1c results from one or more variants which could adversely affect patient care.

Abstract
BACKGROUND Hemoglobin A1c (HbA1c) is used to monitor long-term glycemic control in individuals with diabetes, guide therapy, predict the risk of microvascular complications, and more recently to diagnose diabetes. An automated liquid-flow capillary electrophoresis method was recently developed to measure HbA1c using the Capillarys 2 Flex Piercing instrument. METHODS Analytical evaluation was performed at 2 clinical centers. A clinical analysis was conducted in 109 African-born individuals, 24% of whom have variant hemoglobin (HbAS or HbAC). Abnormal glucose tolerance (which includes both diabetes and prediabetes) was defined as 2h glucose of ≥ 140 mg/dl (7.8 mmol/l) during an oral glucose tolerance test. RESULTS Interlaboratory CVs were ≤ 2.1%. The method showed satisfactory correlation with 2 other analyzers that measure HbA1c by high-performance liquid chromatography. Neither labile HbA1c, carbamylated hemoglobin, uremia, bilirubin nor common hemoglobin variants (HbC/HbS/HbE) interfered. Forty-five individuals (41%) had abnormal glucose tolerance. The sensitivity of HbA1c for diagnosing abnormal glucose tolerance was 38%, 36% and 42% for total, normal and variant hemoglobin groups, respectively. CONCLUSIONS The analytical performance of HbA1c on the Capillarys 2 is suitable for clinical application. Variant hemoglobin in Africans did not interfere with the detection of abnormal glucose tolerance by HbA1c measured on the Capillarys 2.

Abstract
Pseudomonas aeruginosa (PA) is commonly isolated from the respiratory secretions of antibody deficiency patients, but the significance of this has not been well studied. We have reviewed our adult antibody deficiency cohort of 179 patients and assessed the prevalence and characteristics of PA infection and the effects of early antibiotic eradication treatments. Of the 34 patients with PA, 55.9% (19) underwent successful eradication and were infection-free, 38.2% (13) had intermittent infection, and 5.9% (2) had chronic PA. PA infection was significantly associated with bronchiectasis (p < 0.0001), with 36.1% (22 out of 61) of patients with bronchiectasis developing a PA infection. Infection status was also significantly associated with chronic sinusitis (p < 0.0001). Most treated PA exacerbations were symptomatic and with colony counts of ≥1000 cfu/ml. Current eradication protocols used at our center involve early treatment at first positive isolate with ciprofloxacin for 3 weeks and nebulized colomycin for 3 months, and if eradication fails, intravenous ceftazidime and gentamycin or colomycin is administered for 2 weeks. Continued sputum surveillance and early eradication treatments upon positive PA culture may help to limit chronic PA infection in antibody deficiency patients.

Abstract
BACKGROUND Rituximab, a chimeric monoclonal antibody against CD20, is increasingly used in the treatment of B-cell lymphomas and autoimmune conditions. Transient peripheral B-cell depletion is expected following rituximab therapy. Although initial clinical trials did not show significant hypogammaglobulinaemia, reports of this are now appearing in the literature. METHODS We performed a retrospective review of patients previously treated with rituximab that were referred to Clinical Immunology with symptomatic or severe hypogammaglobulinaemia. Patient clinical histories, immunological markers, length of rituximab treatment and need for intravenous immunoglobulin replacement therapy (IVIG) were evaluated. An audit of patients receiving rituximab for any condition in a 12-month period and frequency of hypogammaglobulinaemia was also carried out. RESULTS We identified 19 post-rituximab patients with persistent, symptomatic panhypogammaglobulinaemia. Mean IgG level was 3.42 ± 0.4 g/l (normal range 5.8-16.3 g/l). All patients had reduced or absent B-cells. Haemophilus Influenzae B, tetanus and Pneumococcal serotype-specific antibody levels were all reduced and patients failed to mount an immune response post-vaccination. Nearly all of them ultimately required IVIG. The mean interval from the last rituximab dose and need for IVIG was 36 months (range 7 months-7 years). Of note, 23.7% of 114 patients included in the audit had hypogammaglobulinaemia. CONCLUSION With the increasing use of rituximab, it is important for clinicians treating these patients to be aware of hypogammaglobulinaemia and serious infections occurring even years after completion of treatment and should be actively looked for during follow-up. Referral to clinical immunology services and, if indicated, initiation of IVIG should be considered.

Abstract
BACKGROUND Hemoglobin A1c (HbA1c) is an important index of average glycemia in patients with diabetes mellitus that is widely used in clinical trials and large-scale epidemiological studies. Previous studies have shown that adverse sample storage conditions can cause erroneous HbA1c results. We examined the effect of storage at different temperatures with five current HbA1c methods: Tosoh G7 and G8 (Tosoh Bioscience, Inc., South San Francisco, CA) and Bio-Rad Variant™ II (Bio-Rad Laboratories, Hercules, CA) (all ion-exchange high-performance liquid chromatography); Siemens DCA 2000+ (Siemens Healthcare Diagnostics, Deerfield, IL) (immunoassay); and Trinity Biotech (Kansas City, MO) ultra(2) (boronate-affinity high-performance liquid chromatography). METHODS Five whole blood specimens with different HbA1c levels were analyzed by each assay method on Day 0 and then divided into aliquots that were stored at six different temperatures (-70°C, -20°C, 4°C, room temperature, 30°C, and 37°C) for analyses on subsequent days out to Day 84. Acceptance limits were defined as within ±3 SD of all -70°C results or ±0.2% HbA1c, whichever was wider, for each sample. Stability was considered acceptable for a given temperature only if results for all five specimens were acceptable on that day. RESULTS The DCA 2000+ demonstrated the best stability at -20°C and room temperature, whereas the ultra(2) showed the best stability with specimens stored at 4°C. No methods demonstrated stability at 30°C or 37°C for more than 3 days. CONCLUSIONS Exposure of specimens to high temperatures should be avoided regardless of assay methodology. For the ion-exchange methods tested 4°C storage is preferable to -20°C (stability 14-21 days vs. 4-10 days). For studies where long-term stability is required, samples should be stored at -70°C or colder.

Abstract
BACKGROUND Infant growth and lifestyle are now recognized as being critical determinants of later obesity. EMPOWER (Empowering Parents to Prevent Obesity at Weaning: Exploratory Research) was developed as an intervention for parents whose babies are at high risk. Delivered by specially trained health visitors, it is underpinned by the Family Partnership Model and uses a strengths-based, solution-focused way of working with families. METHODS Mothers of babies participating in the pilot of EMPOWER in Leeds were recruited to take part in a study to examine perceptions about the programme's acceptability and usefulness. Interviews were taped and transcribed, and thematic analysis undertaken. RESULTS Families talked positively about the approach of the EMPOWER health visitor with her emphasis on listening, partnership working and shared problem-solving. Parents particularly valued the use of a non-judgemental approach, which they felt had helped them to discuss openly, sensitive issues such as weight and diet. They identified a number of important benefits ranging from increased knowledge about the most appropriate types and amount of food to feed their toddler, to more far-reaching changes within the family as a whole, including modifications to their own diet and lifestyle. Programmes of this nature were perceived as more valuable than the standard help that is currently available. CONCLUSION The EMPOWER programme appears to be both acceptable and valued by targeted parents and a potentially effective means of supporting high-risk families to prevent their children from developing obesity. An exploratory randomized controlled trial is now underway to ascertain the feasibility of conducting a definitive phase 3 trial.

Abstract
Dense deposit disease (DDD) is strongly associated with the uncontrolled activation of the complement alternative pathway. Factor H (CFH)-deficient (Cfh−/−) mice spontaneously develop C3 deposition along the glomerular basement membrane (GBM) with subsequent development of glomerulonephritis with features of DDD, a lesion dependent on C3 activation. In order to understand the role of CFH in preventing renal damage associated with the dysregulation of the alternative pathway we administered purified mouse CFH (mCFH) to Cfh−/− mice. 24 h following the administration of mCFH we observed an increase in plasma C3 levels with presence of intact C3 in circulation showing that mCFH restored control of C3 activation in fluid phase. mCFH resulted in the reduction of iC3b deposition along the GBM. The exogenous mCFH was readily detectable in plasma but critically not in association with C3 along the GBM. Thus, the reduction in GBM C3 was dependent on the ability of mCFH to regulate C3 activation in plasma. Western blot analysis of glomeruli from Cfh−/− mice demonstrated the presence of iC3b. Our data show that the C3 along the GBM in Cfh−/− mice is the C3 fragment iC3b and that this is derived from plasma C3 activation. The implication is that successful therapy of DDD is likely to be achieved by therapies that inhibit C3 turnover in plasma.

Abstract
Abstract
Abstract #5116
Background: Neoadjuvant combinations of gemcitabine (G), anthracyclines and taxanes have demonstrated significant activity with pCR rates of 20-25% albeit with significant myelosuppression. Secreted protein acidic rich in cysteine (SPARC) is an albumin binding protein that mediates intratumoral accumulation of nab-paclitaxel (nab-P) via a SPARC-albumin specific binding activity. This study was designed to evaluate a biweekly schedule of neoadjuvant nab paclitaxel (nab-P) with gemcitabine and epirubicin (E). SPARC tumor assessments were performed in consenting patients (pts) with subsequent pathologic and survival correlatives.
 Methods: Eligibility: Clinical T1c-T4d and/or N0-3, M0 breast cancer (T1N0M0 excluded), ECOG PS 0-2, normal LVEF. ER/PR/HER2 obtained for all pts. Treatment: 6 cycles neoadjuvant G 2000 mg/m2, E 50 mg/m2, and nab-P 175 mg/m2 q14 days followed by surgery. Post operative therapy: 4 cycles G 2000 mg/m2 and nab-P 220 mg/m2 q14 days. Myeloid growth factors were mandated with all cycles. 2 antibody reagents were used to probe for SPARC expressions. For this study, level 3 immunohistochemical (IHC) SPARC staining was considered positive. Results: 123 pts have enrolled with pathologic responses available for 106. 82 pts consented to SPARC testing. Median age 51 (29-72). Median tumor size 4.5 cm. Histology: 81% ductal, 10% lobular, 9% other. 42% ER and PR negative. 55% clinical T3/T4 and 66% lymph node positive at presentation. G3/4 toxicity present in >5% of pts: neutropenia 16% (febrile neutropenia 1 pt), thrombocytopenia 9% with arthralgias 11%, fatigue 10%, and infection 7%. 20 pts did not complete study treatment for the following reasons: disease progression 7, toxicity 3, pt/MD request 5, and other 5. pCR was noted in 23 pts (22%) with PRs in 76 pts (71%), and 6 SD. SPARC IHC staining was available for 76 tumors. SPARC level 3 IHC staining was noted in 65 tumors (86%); 65% were associated with a PR or pCR. Median PFS was 23 months and overall survival at 24 months is 77%. Pts who relapsed ≤16 months from diagnosis were more likely to be triple negative (p = 0.04), or ER negative (p = 0.001), or PR negative (p = 0.0006). Conclusions: Neoadjuvant dose dense GEA is active and better tolerated than other gemcitabine/anthracycline/taxane combinations. The pCR rate of 22% compares favorably with other comparable neoadjuvant regimens albeit with minimal toxicity. Pts with early relapse defined as ≤16 months from diagnosis were more likely to demonstrate a triple negative phenotype or demonstrate estrogen or progesterone receptor negativity. SPARC tumor correlatives with progression free and overall survival are on ongoing and will be presented.

Abstract
Abstract #3148
Background: Vinflunine (VFL) is a novel microtubule inhibitor agent of the vinca alkaloid class that inhibits tubulin polymerization without stabilization, resulting in cell cycle arrest in mitosis and apoptosis. Weak tubulin binding at the vinca-binding site accounts for its reduced neurotoxicity. VFL has demonstrated activity in anthracycline and taxane pretreated patients (pts) and in combination with capecitabine. This trial evaluates the activity and safety of VFL monotherapy and in combination with trastuzumab (T) in HER2+ pts as 1st line therapy metastatic breast cancer (MBC).
 Methods: Eligibility: 0 prior regimens for MBC, > 6 mo from adjuvant therapy, RECIST criteria measurable disease, ECOG PS 0-2, adequate organ function, peripheral neuropathy < G2. Treatment: HER2 unspecified: VFL 320 mg/m2 IV q3 wks; FISH HER2+ pts: VFL 280 mg/m2 plus T 6 mg/kg q3 wks. Response evaluations q9 wks; treatment continued until disease progression or toxicity.
 Results: Due to termination of VFL licensing between BMS and Pierre Fabre Medicament, the study closed prematurely with only 31 evaluable pts of a planned 48 pts in each treatment arm of VFL monotherapy or VFL in combination with T. 10 pts received VFL and 21 pts were treated with VFL + T. Median age: 59 yrs (35-78). ECOG PS 0-18 pts, 1-11 pts, 2-2 pts. 48% were ER+. Prior adjuvant anthracyclines and taxanes noted in 17 and 19 pts respectively. 4 pts presented with de novo stage IV disease, all HER2 positive. 45% had 3 or more metastatic disease sites with bone (17 pts), liver (16 pts) and lung (15 pts) predominating. Median of # cycles: 4 (range 1-19). There were 10 PRs (32%), all in VFL + T, and 9 pts (29%) with PD (VFL-4 pts, VFL + T-5pts). SD was reported in 10 pts (32%). 2 pts (7%) were unevaluable, divided equally between the two arms. G3/4 neutropenia occurred in 11 pts (35%); none with fever. G3 nonhematologic toxicity consisted of pain, attributed to treatment in 5 pts (16%) (sites: abdomen-2, chest, back, and infusion site each in 1 pt), and GI toxicity characterized by N/V 3 pts (10%) as well as abdominal pain, diarrhea, constipation, occurring each in 2 pts (6%). There were no G4 events. 10 pts were hospitalized (GI -4 pts, pain 2 pts, pulmonary 2 pts, and other 2 pts). Median PFS was 3.5 months for VFL and 6.6 months for VFL + T. Median overall survival was 9 months for VFL and has not been reached for VFL + T.
 Conclusions: The combination of vinflunine and trastuzumab is active in the first line treatment of MBC, producing a 48% response rate. Adverse events were as expected, manageable and consisted primarily of neutropenia, pain and GI toxicity. This encouraging activity compares favorably with other trastuzumab combination regimens and merits further evaluation.

Abstract
Little is known about determinants regulating expression of Mannan-binding lectin associated serine protease-2 (MASP-2), the effector component of the lectin pathway of complement activation. Comparative bioinformatic analysis of the MASP2 promoter regions in human, mouse, and rat, revealed conservation of two putative Stat binding sites, termed StatA and StatB. Site directed mutagenesis specific for these sites was performed. Transcription activity was decreased 5-fold when StatB site was mutated in the wildtype reporter gene construct. Gel retardation and competition assays demonstrated that proteins contained in the nuclear extract prepared from HepG2 specifically bound double-stranded StatB oligonucleotides. Supershift analysis revealed Stat3 to be the major specific binding protein. We conclude that Stat3 binding is important for MASP2 promoter activity.

Abstract
Enzyme replacement therapy (ERT) has been developed for several lysosomal storage disorders, including mucopolysaccharidosis I (MPS I), and is effective at reducing lysosomal storage in many tissues and in ameliorating clinical disease. However, intravenous ERT does not adequately treat storage disease in the central nervous system (CNS), presumably due to effects of the blood-brain barrier on enzyme distribution. To circumvent this barrier, we studied whether intrathecal (IT) recombinant human alpha-L-iduronidase (rhIDU) could penetrate and treat the brain and meninges. An initial dose-response study showed that doses of 0.46-4.14 mg of IT rhIDU successfully penetrated the brain of normal dogs and reached tissue levels 5.6 to 18.9-fold normal overall and 2.7 to 5.9-fold normal in deep brain sections lacking CSF contact. To assess the efficacy and safety in treating lysosomal storage disease, four weekly doses of approximately 1 mg of IT rhIDU were administered to MPS I-affected dogs resulting in a mean 23- and 300-fold normal levels of iduronidase in total brain and meninges, respectively. Quantitative glycosaminoglycan (GAG) analysis showed that the IT treatment reduced mean total brain GAG to normal levels and achieved a 57% reduction in meningeal GAG levels accompanied by histologic improvement in lysosomal storage in all cell types. The dogs did develop a dose-dependent immune response against the recombinant human protein and a meningeal lymphocytic/plasmacytic infiltrate. The IT route of ERT administration may be an effective way to treat the CNS disease in MPS I and could be applicable to other lysosomal storage disorders.

Abstract
Activation of the lectin pathway of complement is initiated by the binding to microbial carbohydrate structures of a multimolecular fluid-phase complex composed of a carbohydrate recognition subcomponent that associates with three specific serine proteases and an enzymatically inert protein of 19 kDa. The first carbohydrate recognition subcomponent of the lectin pathway identified was mannan-binding lectin (MBL), hence the serine proteases were named MBL-associated serine proteases (MASPs) and numbered according to the sequence of their discovery. Here we describe the primary structures of the two distinct serine proteases MASP-1 and MASP-3 in the rat (and of MASP-3 in the mouse), show their association with plasma MBL complexes, and demonstrate that in rat and mouse, as in man, MASP-1 and MASP-3 are encoded by a single structural gene. For both species, we present the genomic region and regulatory elements responsible for the processing of either MASP-1 or MASP-3 mRNA by alternative splicing/alternative polyadenylation. Furthermore, we demonstrate the evolutionary conservation of MASP-3 mRNA in cDNA transcripts from guinea pig, rabbit, pufferfish, and cow.

Abstract
BACKGROUND The validity of the Cup:Disc (C:D) ratio as a clinical measure depends on the level of agreement among observers. In this study, we investigated the effect of observer experience on interobserver and intraobserver agreement in C:D ratio estimation. METHODS Nine 3rd-year (Yr3) and nine 4th-year (Yr4) optometry students and nine optometrists (Opt), determined C:D ratios from 26 optic disc photographs viewed monoscopically and stereoscopically. Observer agreement was investigated using weighted kappa (Kw) analysis. RESULTS Interobserver agreement was higher (p < 0.01) among optometrists than among 4th-year students and higher (p < 0.01) among 4th-year than among 3rd-year students (mean Kw: Opt = 0.61; Yr4 = 0.51; Yr3 = 0.39). Stereoscopic estimates of C:D ratios were higher (p < 0.0001) than monoscopic estimates, and interobserver agreement was higher (p < 0.001) when evaluating the vertical rather than the horizontal C:D ratio. Intraobserver agreement (mean Kw: Opt = 0.67; Yr4 = 0.66; Yr3 = 0.62) did not vary significantly (p = 0.78) with experience. CONCLUSIONS The extent to which an observer reproducibly assesses the C:D ratio from optic disc photographs (intraobserver agreement) does not increase with experience. However, the agreement between different observers in assessing the C:D ratio (interobserver agreement) increases with experience.

Abstract
BACKGROUND Thrombolytic therapy for acute ischemic stroke with IV alteplase is increasingly well established in North America but not elsewhere. Baseline factors that altered the response to alteplase were not identified by the National Institute of Neurological Disorders and Stroke tPA Stroke Study Group. METHODS The authors gathered information from centers in the United States, Canada, and Germany on 1,205 patients with acute ischemic stroke treated with IV alteplase. The purpose was to identify independent factors that were predictive of good outcome using multivariable logistic regression modelling. The modified Rankin Scale score was dichotomized into good outcome (mRS 0 to 1) and poor outcome (mRS >1) as the primary outcome measure. RESULTS In relative order of decreasing magnitude, milder baseline stroke severity, no history of diabetes mellitus, normal CT scan, normal pretreatment blood glucose level, and normal pretreatment blood pressure were independent predictors of good outcome among patients treated with IV alteplase for acute ischemic stroke. Confounding was observed among history of diabetes mellitus, CT scan appearance, baseline serum glucose level, and blood pressure, suggesting important relationships among these variables. CONCLUSIONS Several factors were independently predictive of good outcome among patients with acute ischemic stroke treated with alteplase. These results require further confirmation before clinical implementation.

Abstract
The soothing, repetitive movement of rocking and swinging is well known to anyone who has enjoyed a porch swing or rocking chair. Positive effects of rocking have been reported. However, investigations on its effect in people with dementia are limited. The purposes of this quasi-experimental, repeated-measures design study were to measure the effects of a glider swing on emotions, relaxation, and aggressive behaviors in a group of nursing home residents with dementia (n = 30). Data were obtained during a 5-day baseline phase, a 10-day intervention phase, and a 5-day posttreatment phase. Subjects were placed on the glider for 20 minutes each day during the intervention phase. The results of the study indicate that the glider intervention significantly improved emotions and relaxation. The most noted changes were found after 10 minutes of swinging. However, no differences were found in aggressive behaviors.

Abstract
This article provides an overview of the development and implementation of a management development strategy for the South Western Sydney Area Health Service (SWSAHS). The program, the Frontline Management Initiative (FMI), was introduced as a developmental tool which enabled managers to identify those competencies that they already possess and those which they need to develop. The FMI will be progressively implemented throughout the five sector health services of SWSAHS comprising approximately 1500 managers. This article outlines the introduction and experience of FMI in one sector health service, the development and assessment of a manager's portfolio, the pathway developed from FMI to university based health management courses, the lessons learnt and the future directions for management development.

Abstract
Addressing abusive behavior in the medical workplace presents an important opportunity to deliver on the national commitment to improve patient safety. Fundamentally, the issue of patient safety and the issue of abusive behavior in the workplace are both about harm. Undiagnosed and untreated, abusive behavior is a barrier to creating high reliability service delivery systems that ensure patient safety. Health care managers and clinicians need to improve their awareness, knowledge, and understanding of the issue of workplace abuse. The available research suggests there is a high prevalence of workplace abuse in medicine. Both administrators at the blunt end and clinicians at the sharp end should consider learning new approaches to defining and treating the problem of workplace abuse. Eliminating abusive behavior has positive implications for preventing and controlling medical injury and improving organizational performance.

Abstract
Integration in health sector reform tends to mean horizontal interaction between vertical programmes. This can result in a larger more complex system than a set of individual vertical programmes. This article looks at the HIV/AIDS programme in Tanzania and the possible impact of system-wide health sector reform involving 'decentralization' and horizontal integration. It implies that the build-up to reform is likely to be costly, at least initially (although eventually the system may become more cost-effective). Integration can thus save resources, but it will also demand additional inputs, and may lead to reduced service output if operations depend on horizontal functions that fail to deliver. The objective of reform must be to create a reasonably sized, well-balanced, system which aims to maximize the output of quality services, both preventive and curative, and to facilitate community efforts to improve health. It is doubtful whether present reform efforts in Tanzania will contribute to more effective services, if not based on a more thorough analysis adapted to the local situation and given considerably more resources, both human and financial. There is also a risk that key preventive programmes, such as those aimed at the control of STD/AIDS, will be further weakened because of both integration with subsequent dependence on poorly functioning horizontal units and reduction in allocated resources.

Abstract
A series of new enantiomerically pure 3-amino-3,4-dihydro-2H-1-benzopyrans (3-aminochromans) has been synthesized from (R)- and (S)-5-methoxy-3-amino-3,4-dihydro-2H-1-benzopyran. The absolute configuration of the respective (R)- and (S)-enantiomers was deduced from X-ray crystallography of (R)-3-(N-isopropylamino)-5-methoxy-3,4-dihydro-2H-1-benzopyran, (R)-9a. Various 5-substituents were introduced via palladium-catalyzed carbonylation of N-substituted 3-amino-5-trifluoromethanesulfonyloxy-3,4-dihydro-2H-1-benzopyran. The effect of N- and 5-substitution on affinity for the 5-HT1A receptor was evaluated in competition experiments using rat hippocampal membranes and [3H]8-OH-DPAT as radioligand. Selected compounds were also tested for their affinity to the D1 (rat striatum), D2 (rat striatum), D2A (human cloned), and 5-HT2A (rat cortex) receptors. The intrinsic activity of the compounds was evaluated by measuring their effect on VIP-stimulated cAMP production in GH4ZD10 cells stably transfected with the 5-HT1A receptor. High-affinity compounds with high selectivity for the 5-HT1A receptor were found among structures substituted with carboxylate esters, amides, and ketones in the 5-position. Primary and secondary amines bound with lower affinity than tertiary amines. Larger substituents were well-tolerated by the receptor, but the smaller N-ethyl-N-isopropyl bound with lower affinity. Generally, the (R)-enantiomers displayed higher affinity for the 5-HT1A receptor than the corresponding (S)-enantiomers. In the present series of compounds, both full and partial agonists were found.

Abstract
OBJECTIVE To compare examination time and visual field loss for ptosis fields obtained with manual kinetic (Goldmann) perimetry and automated static (Humphrey) perimetry. METHODS Both eyes of 12 patients with bilateral aponeurogenic ptosis were prospectively examined using Goldmann and Humphrey (ptosis protocol) perimetry with the eyelids ptotic and taped into a normal position. RESULTS Bilateral examination time for Goldmann fields was 10 +/- 2 minutes and for Humphrey fields was 50 +/- 10 minutes (P<.001, n = 12). Superior fields at the 12:00 meridian were 46 degrees +/- 6 degrees taped, and 28 degrees +/- 12 degrees untaped for Goldmann perimetry (P<.001), and 38 degrees +/- 8 degrees taped, and 24 degrees +/- 12 degrees untaped for Humphrey perimetry P<.001). Goldmann field loss was 18 degrees +/- 9 degrees (taped minus untaped). Humphrey field loss was 14 degrees +/- 13 degrees (P<.04, n = 24). Mean Goldmann radial fields were 56 degrees +/- 6 degrees taped and 39 degrees +/- 13 degrees untaped (P<.001). Goldmann superior hemifield areas were 5,167 +/- 964 degrees2 taped and 2,830 +/- 1,466 degrees2 untaped (P<.001). Humphrey mean vertical superior hemifield was 37 degrees +/- 9 degrees taped and 21 degrees +/- 11 degrees untaped (P<.001). Mean sensitivity of Humphrey fields was 15 +/- 3 dB taped and 9 +/- 5 dB untaped (P<.001). Mean vertical center of gravity was 23 degrees +/- 3 degrees taped and 16 degrees +/- 5 degrees untaped (P <.001). CONCLUSION Goldmann manual kinetic and Humphrey automated static visual field testing are both effective in documenting ptosis associated visual field loss. Humphrey automated ptosis fields, as performed in this study, require longer examination times than Goldmann manual fields and may be a less sensitive indicator of field loss.

Abstract
To compare the length of stay and charges for patients with pneumonia admitted in 1995 to the teaching and nonteaching services of a Northeastern teaching hospital, we reviewed the charts of 237 patients. Patients cared for by hospital-based generalists working with housestaff (teaching service) were discharged more quickly and with lower or equivalent charges than patients cared for by community-based attending physicians working either with housestaff (private teaching service) or alone (nonteaching service). Academic teaching services staffed by general medicine faculty may provide efficient inpatient pneumonia care.

Abstract
C-Raf is a an essential member of the growth factor-ras pathway and a target for intervention strategies aimed at blocking cell proliferative responses. Excessive smooth muscle proliferation is considered one cause of the arterial closure in restenosis. Because of the similarity to the human cardiovascular system, a useful current animal model of the disease is a baboon model. As a foundation for animal studies employing antisense oligonucleotides, efforts were made to characterize the molecular and cellular biology of the baboon system. The nucleotide sequence of baboon c-raf cDNA was determined. Antisense phosphorothioate oligonucleotides specific to the 3'-UTR of c-raf mRNA from human and baboon were compared using primary baboon smooth muscle cells in culture. A particular human antisense oligonucleotide, referred to as ISIS 5132, was different by only 2 of 20 bases from the baboon sequence. The corresponding baboon antisense oligonucleotide ISIS 12959, however, was markedly more effective to inhibit c-raf mRNA, protein production, and DNA synthesis, and the results attest to the species specificity of the approach. After antisense treatment, c-raf mRNA levels dropped rapidly, whereas protein levels decreased with a half-life of roughly 24-48 hours, consistent with the antiproliferative effects. The data are discussed with regard to the profile of protein-protein interactions made by C-Raf and with the view that the baboon system closely parallels the human one at the signal transduction level. As this work progressed, a baboon cDNA homolog of a human c-raf-2 pseudogene was isolated, sequenced, and shown to be transcribed into mRNA.

Abstract
PURPOSE To evaluate the outcomes of a structured, educational, and support group intervention (ISEE, Intervention for Siblings: Experience Enhancement) for siblings of children with chronic illness (cancer, cystic fibrosis, diabetes, and spina bifida), including a session with parents about sibling needs; and to describe sibling and parent perceptions of sibling experiences at home. DESIGN One-group, pretest-posttest pilot study. PARTICIPANTS A convenience sample of 22 siblings and parents. SETTING A Midwestern university medical center. MAIN OUTCOME MEASURES Knowledge of Illness Test, parent ratings on a global, single item, 10-point scale. RESULTS Sibling test scores increased significantly after intervention, compared to baseline. Parents' average evaluation rating was 9 on a 10-point scale. Parents supported their positive ratings with verbatim descriptions. Sibling and parent perceptions of sibling experiences were congruent, suggesting the sources of potential adjustment problems in siblings, and were consistent with the literature. CONCLUSIONS A randomized, clinical trial with a larger sample size is needed to evaluate the intervention further.

Abstract
The species composition, abundance, and distribution of mosquito larvae in tires were determined on 3 dates at a relatively large rural tire dump (about 300,000 tires) in southeastern IL (Jasper County). Several observations at this site differed from those in previous reports about mosquitoes in tireyards, including 1) a relatively high percentage of tires positive for Aedes triseriatus larvae in an open-field area, 2) a greater abundance of Culex pipiens than Cx. restuans in late-season collections, 3) a seasonal change in the distribution of Aedes atropalpus larvae in tires from open field and edge of woods areas, and 4) the presence of Ae. albopictus as a major late-season species. Ae. albopictus adults were captured in sod-baited gravid traps along the edge of a wooded riparian area 200 m from the tire pile.
