Abstract
BACKGROUND Sodium-glucose co-transporter-2 (SGLT2) inhibitors reduce progression of chronic kidney disease and the risk of cardiovascular morbidity and mortality in a wide range of patients. However, their effects on kidney disease progression in some patients with chronic kidney disease are unclear because few clinical kidney outcomes occurred among such patients in the completed trials. In particular, some guidelines stratify their level of recommendation about who should be treated with SGLT2 inhibitors based on diabetes status and albuminuria. We aimed to assess the effects of empagliflozin on progression of chronic kidney disease both overall and among specific types of participants in the EMPA-KIDNEY trial. METHODS EMPA-KIDNEY, a randomised, controlled, phase 3 trial, was conducted at 241 centres in eight countries (Canada, China, Germany, Italy, Japan, Malaysia, the UK, and the USA), and included individuals aged 18 years or older with an estimated glomerular filtration rate (eGFR) of 20 to less than 45 mL/min per 1·73 m2, or with an eGFR of 45 to less than 90 mL/min per 1·73 m2 with a urinary albumin-to-creatinine ratio (uACR) of 200 mg/g or higher. We explored the effects of 10 mg oral empagliflozin once daily versus placebo on the annualised rate of change in estimated glomerular filtration rate (eGFR slope), a tertiary outcome. We studied the acute slope (from randomisation to 2 months) and chronic slope (from 2 months onwards) separately, using shared parameter models to estimate the latter. Analyses were done in all randomly assigned participants by intention to treat. EMPA-KIDNEY is registered at ClinicalTrials.gov, NCT03594110. FINDINGS Between May 15, 2019, and April 16, 2021, 6609 participants were randomly assigned and then followed up for a median of 2·0 years (IQR 1·5-2·4). Prespecified subgroups of eGFR included 2282 (34·5%) participants with an eGFR of less than 30 mL/min per 1·73 m2, 2928 (44·3%) with an eGFR of 30 to less than 45 mL/min per 1·73 m2, and 1399 (21·2%) with an eGFR 45 mL/min per 1·73 m2 or higher. Prespecified subgroups of uACR included 1328 (20·1%) with a uACR of less than 30 mg/g, 1864 (28·2%) with a uACR of 30 to 300 mg/g, and 3417 (51·7%) with a uACR of more than 300 mg/g. Overall, allocation to empagliflozin caused an acute 2·12 mL/min per 1·73 m2 (95% CI 1·83-2·41) reduction in eGFR, equivalent to a 6% (5-6) dip in the first 2 months. After this, it halved the chronic slope from -2·75 to -1·37 mL/min per 1·73 m2 per year (relative difference 50%, 95% CI 42-58). The absolute and relative benefits of empagliflozin on the magnitude of the chronic slope varied significantly depending on diabetes status and baseline levels of eGFR and uACR. In particular, the absolute difference in chronic slopes was lower in patients with lower baseline uACR, but because this group progressed more slowly than those with higher uACR, this translated to a larger relative difference in chronic slopes in this group (86% [36-136] reduction in the chronic slope among those with baseline uACR <30 mg/g compared with a 29% [19-38] reduction for those with baseline uACR ≥2000 mg/g; ptrend<0·0001). INTERPRETATION Empagliflozin slowed the rate of progression of chronic kidney disease among all types of participant in the EMPA-KIDNEY trial, including those with little albuminuria. Albuminuria alone should not be used to determine whether to treat with an SGLT2 inhibitor. FUNDING Boehringer Ingelheim and Eli Lilly.

Impact of primary kidney disease on the effects of empagliflozin in patients with chronic kidney disease: secondary analyses of the EMPA-KIDNEY trial. Lancet Diabetes Endocrinol 2024; 12:51-60. [PMID: 38061372 DOI: 10.1016/s2213-8587(23)00322-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/05/2023] [Revised: 10/24/2023] [Accepted: 10/25/2023] [Indexed: 12/23/2023]
Abstract
BACKGROUND The EMPA-KIDNEY trial showed that empagliflozin reduced the risk of the primary composite outcome of kidney disease progression or cardiovascular death in patients with chronic kidney disease mainly through slowing progression. We aimed to assess how effects of empagliflozin might differ by primary kidney disease across its broad population. METHODS EMPA-KIDNEY, a randomised, controlled, phase 3 trial, was conducted at 241 centres in eight countries (Canada, China, Germany, Italy, Japan, Malaysia, the UK, and the USA). Patients were eligible if their estimated glomerular filtration rate (eGFR) was 20 to less than 45 mL/min per 1·73 m2, or 45 to less than 90 mL/min per 1·73 m2 with a urinary albumin-to-creatinine ratio (uACR) of 200 mg/g or higher at screening. They were randomly assigned (1:1) to 10 mg oral empagliflozin once daily or matching placebo. Effects on kidney disease progression (defined as a sustained ≥40% eGFR decline from randomisation, end-stage kidney disease, a sustained eGFR below 10 mL/min per 1·73 m2, or death from kidney failure) were assessed using prespecified Cox models, and eGFR slope analyses used shared parameter models. Subgroup comparisons were performed by including relevant interaction terms in models. EMPA-KIDNEY is registered with ClinicalTrials.gov, NCT03594110. FINDINGS Between May 15, 2019, and April 16, 2021, 6609 participants were randomly assigned and followed up for a median of 2·0 years (IQR 1·5-2·4). Prespecified subgroupings by primary kidney disease included 2057 (31·1%) participants with diabetic kidney disease, 1669 (25·3%) with glomerular disease, 1445 (21·9%) with hypertensive or renovascular disease, and 1438 (21·8%) with other or unknown causes. Kidney disease progression occurred in 384 (11·6%) of 3304 patients in the empagliflozin group and 504 (15·2%) of 3305 patients in the placebo group (hazard ratio 0·71 [95% CI 0·62-0·81]), with no evidence that the relative effect size varied significantly by primary kidney disease (pheterogeneity=0·62). The between-group difference in chronic eGFR slopes (ie, from 2 months to final follow-up) was 1·37 mL/min per 1·73 m2 per year (95% CI 1·16-1·59), representing a 50% (42-58) reduction in the rate of chronic eGFR decline. This relative effect of empagliflozin on chronic eGFR slope was similar in analyses by different primary kidney diseases, including in explorations by type of glomerular disease and diabetes (p values for heterogeneity all >0·1). INTERPRETATION In a broad range of patients with chronic kidney disease at risk of progression, including a wide range of non-diabetic causes of chronic kidney disease, empagliflozin reduced risk of kidney disease progression. Relative effect sizes were broadly similar irrespective of the cause of primary kidney disease, suggesting that SGLT2 inhibitors should be part of a standard of care to minimise risk of kidney failure in chronic kidney disease.

Abstract
Falls are one of the most costly population health issues. Screening of older adults for fall risks can allow for earlier interventions and ultimately lead to better outcomes and reduced public health spending. This work proposes a solution to limitations in existing fall screening techniques by utilizing a hip-based accelerometer worn in free-living conditions. The work proposes techniques to extract fall risk features from periods of free-living ambulatory activity. Analysis of the proposed techniques is conducted and compared with existing screening methods using Functional Tests and Lab-based Gait Analysis. 1705 Older Adults from Umea (Sweden) were assessed. Data consisted of 1 Week of hip worn accelerometer data, gait measurements and performance metrics for 3 functional tests. Retrospective and Prospective fall data were also recorded based on the incidence of falls occurring 12 months before and after the study commencing respectively. Machine learning based experiments show accelerometer based measures perform best when predicting falls. Prospective falls had a sensitivity and specificity of 0.61 and 0.66 respectively while retrospective falls had a sensitivity and specificity of 0.61 and 0.68 respectively.

Abstract
BackgroundBiologic therapies used in the management of rheumatoid arthritis (RA) target several cytokines that have been implicated in the pathogenesis of multiple myeloma (MM). Yet little is known about the association between use of biologic or targeted synthetic disease modifying anti-rheumatic drugs (b or tsDMARDs) in RA and the incidence of MM.ObjectivesOur objective was to estimate the association between b/tsDMARD use and the risk of MM among persons with RA using Veterans Health Administration (VHA) data. We hypothesized that b-/tsDMARD use is associated with a lower incidence of MM compared with conventional synthetic DMARDs (csDMARDs).MethodsIn this retrospective cohort study, we identified patients >18 years of age diagnosed with RA in any United States VHA facility from 1/1/2002 and 12/31/2018. All patients met the following inclusion criteria: 1) two or more International Classification of Diseases Version 9 or 10 (ICD9 or ICD10) codes for RA at least 7 days apart but no more than 365 days apart 2) a prescription for a csDMARD within 90 days of the first RA diagnosis 3) one inpatient or outpatient visit 30 days to 2 years preceding first RA diagnosis (indicating a regular user of VHA). Medication data was derived from the outpatient prescription fills, bar coded medication administration (BCMA), and intravenous (IV) data domains. The csDMARDs included in these analyses were: methotrexate, sulfasalazine, leflunomide, and hydroxychloroquine. The bDMARDs included were tumor necrosis factor inhibitors (TNFi) and non-TNFi biologics such as tocilizumab, rituximab, abatacept, and biosimilars; tsDMARD was tofacitinib. Patients with MM before the diagnosis of RA were excluded. Incident MM was determined by 1 or more ICD9/10 code or ICD-oncology codes. Multivariable Cox proportional hazards model were performed to estimate the hazard ratio for developing MM among those during and following the use of a b-/tsDMARD relative to b-/tsDMARD-naïve persons adjusting for age, gender, race, and ethnicity.Results27,540 veterans with RA met study eligibility criteria, of whom 8,322 (30%) had taken a b-/tsDMARD. Over the study period there were 77 incident MM over a total of 192,000 person years. There were 55 events in users of csDMARDs, an incidence rate (IR) of 0.40 (95% CI 0.30-0.52) per 1000 person-years and 22 in persons currently or formerly using b-/tsDMARDs (IR 0.41, 0.25-0.61 per 1000 person years). The unadjusted hazard ratio for MM following bDMARD use relative to csDMARD only use was 1.04 (0.63, 1.73), which increased to 1.28 (0.76, 2.16) after adjusting for demographic characteristics (Table 1).Table 1.Multivariable Cox proportional hazards model for association between use of disease modifying anti-rheumatic drugs and incident multiple myeloma.Clinical characteristicHazards ratio (95% CI)csDMARDReferenceb-/tsDMARD use1.28 (0.76-2.16)Age*1.04 (1.02-1.07)Female0.58 (0.20-1.62)RaceReferenceWhite2.11 (1.15-3.86)Black0.70 (0.10-5.08)OtherHispanic Ethnicity0.71 (0.17-2.92)Abbreviations: b-/tsDMARD- biologic or targeted synthetic disease modifying anti-rheumatic drug; CI: confidence interval*Hazards ratio reflects risk per every 1-year increase in ageModel adjusted for age, gender, race, and ethnicityConclusionIn this nationwide VA study, we did not observe an association between bDMARD use and the incidence of MM. Of note, the median interval from initiation of a bDMARD to the end of follow-up was approximately 5.8 years, which does not allow for an examination of a possible longer term influence.Disclosure of InterestsNone declared

Abstract
BackgroundEpidemiologic studies suggest that disease duration and degree of inflammatory activity of rheumatoid arthritis (RA) contribute to lymphoma development (1). Whether the decrease in inflammatory burden seen with use of biologic or targeted synthetic disease modifying anti-rheumatic drugs (bDMARDs or tsDMARDs) translates into a lower risk of lymphoma in RA needs to be studied.ObjectivesThe objective of our study was to examine the effect of administration of b/tsDMARDS on the incidence of lymphoma relative to conventional synthetic DMARDs (csDMARDs) in an inception cohort of Veterans with RA.MethodsWe identified patients >18 years of age diagnosed with RA in any US Veterans Affairs (VA) facility from 1/1/2002 and 12/31/2018 using the VA Corporate Data Warehouse (CDW). To be included, each patient was required to meet the following criteria: 2+ RA diagnostic codes at least 7 days apart but no more than 365 days apart; 2) a prescription for a csDMARD within 90 days of the first RA diagnosis; and 3) an inpatient or outpatient visit 30 days to 2 years preceding first RA diagnosis (indicating they are a regular user of the VA). The csDMARDs included in these analyses were: methotrexate, sulfasalazine, leflunomide, and hydroxychloroquine. The bDMARDs included were tumor necrosis factor inhibitors (TNFi) and non-TNFi biologics such as tocilizumab, rituximab, abatacept, and biosimilars; tsDMARD was tofacitinib. Patients with prevalent lymphoma were excluded. Lymphoma diagnoses were identified using International Classification of Diseases Version 9, 10 and Oncology (ICD9, ICD10, ICDO) codes.We used marginal structural models as described by Hernan et al (2) and time-varying Cox models to control for confounding by indication while evaluating this association. We adjusted for baseline demographics (age, sex, race, ethnicity, year of cohort entry, rheumatology visits), and time-varying CRP and time-varying Rheumatoid Disease Comorbidity Index (RDCI) (3) to control for confounding.Results27,421 Veterans with RA met our eligibility criteria. Most of the Veterans (56%) were in the age range 61-80 years old; 89% male, 76% White, 14% African American. 8,225 (30%) patients were treated with a b-/tsDMARD. The crude incidence rates were 1.71 (95% CI 1.5-1.94) per 1000 person-years for those only on csDMARDs and 1.78 (95% CI 1.44-2.18) for patients during or following use of a b/tsDMARDs. After adjustment with both time-fixed and time-varying covariates using marginal structural models, the incidence of lymphoma was not different between patients who did and did not use a b/tsDMARD (hazard ratio=1.06, 95% CI= 0.82-1.37) (Table 1).Table 1.Estimates of Effect of bDMARD or tsDMARD use on Lymphoma relative to use of csDMARDsMarginal Structural Models; adjusted for:@Demographics1.04(0.80, 1.34)#Demographics + CRP1.06(0.82, 1.37)* per 1000 person-years@Demographics = age, gender, race, ethnicity, rheumatology visits, and year of cohort entry#Adjusts for CRP, baseline rheumatology visits (yes/no) and RDCI.CRP = C-Reactive Protein, RDCI = Rhematic Disease Comorbidity Index, CI = Confidence Interval, b/tsDMARD = biologic or targeted synthetic DMARD, csDMARD = conventional synthetic DMARDConclusionIn this large study using the nationwide VA data, we did not observe an association between the use of b/ts DMARDs and an increased risk of lymphoma.References[1]Baecklund E, Iliadou A, Askling J, Ekbom A, Backlin C, Granath F, et al.

Effect of dietary supplementation of Bacillus subtilis DSM29784 on hen performance, egg quality indices, and apparent retention of dietary components in laying hens from 19 to 48 weeks of age. Poult Sci 2020; 98:5622-5635. [PMID: 31222316 DOI: 10.3382/ps/pez324] [Citation(s) in RCA: 19] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/17/2019] [Accepted: 05/21/2019] [Indexed: 12/19/2022] Open
Abstract
The aim of the current study was to evaluate egg production, quality, and apparent retention (AR) of components in response to a multi-dose application of a single strain Bacillus subtilis (SSB; DSM29784) in a corn-soybean meal basal diet fed to hens (19 to 48 wk of age). The treatments consisted of a basal diet with either no probiotic (control, CON), 1.1E+08 (low, LSSB), 2.2E+08 (medium, MSSB) or 1.1E+09 (high, HSSB) CFU/kg of diet. A total of 336, 19-wk old Shaver White layers were used at a stocking density of 7 and 6 hens/replicate-cage in layer I (week-19 to 28) and layer II (week-29 to 48) phases, respectively. Evaluated variables included feed intake (FI), body weight (BW), feed conversion ratio (FCR), egg production, weight, mass, and egg quality (shell thickness, shell breaking strength, albumen height (AH), and Haugh unit (HU)). Excreta was collected at the end of week-28 for AR of components and apparent metabolizable energy (AME). Supplementation of SSB increased (P = 0.008) FI during peak egg-lay (week-24) and BW increased linearly (P = 0.019) in early layer II (week-32). In layer I, LSSB compared with CON increased EM (g/egg) by 3.3% (P = 0.049). In layer II, SSB inclusion tended to improve FCR (linear, P = 0.094; g FI: g EM). Although shell breaking strength was lowest at week-20 with HSSB (4.518 vs. 4.889 kgf for HSSB vs. CON; P = 0.045), AH and HU were improved at higher dose of SSB, in both phases (P ≤ 0.005). Apparent retention of dry matter, AME, and minerals were improved (P < 0.0001) in a dose response. Hence, while the low dose of B. subtilis DSM29784 improved hen performance and maintained egg quality in both phases, a higher dose of SSB improved the interior protein quality of eggs (AH and HU).

Abstract
Administered in adequate amounts, probiotics can be an alternative to antibiotic growth promoters in poultry production. This study evaluated dose response of a single strain of Bacillus subtilis (SSB, DSM29784) on growth performance, apparent retention (AR) of components, and excreta DM content in pullets. A basal corn-soybean meal diet was formulated to meet the specifications for grower (week 5 to 10) and developer (week 11 to 16) phases. In each phase, SSB was added to the basal diet to create 4 test diets: 0 (control, CON), 1.1E+08 (low; LSSB), 2.2E+08 (medium; MSSB), or 1.1E+09 (high; HSSB) CFU of SSB/kg of feed. All diets had TiO2 (0.5%) as a digestibility marker. A total of 720 day-old Shaver White chicks were placed in 48 cages (15 pullets per cage) and reared on a commercial antibiotic free diet for a 4-wk period. At the beginning of week 5, treatments were allocated based on cage BW (n = 12). Birds had free access to feed and water throughout. The BW, BW uniformity, feed intake (FI) and FCR were obtained weekly. Excreta was collected at the end of each phase for AR of DM, organic matter, CP, neutral detergent fiber, minerals, and AME, as well as excreta DM content. In response to SSB inclusion, BW improved in a linear (P < 0.005) and quadratic (P < 0.0001) manner in grower. FI decreased in a linear and quadratic pattern (P < 0.05, week 8 to 10) in grower, and linearly (P < 0.05) across the developer phase. Overall FCR improved in linear and quadratic pattern (P < 0.01) in the grower phase. In both the phases, AME improved in a quadratic pattern (P < 0.05). Inclusion of SSB had a linear reduction (P < 0.0001) in excreta moisture content in the grower phase. In summary, these results demonstrate that B. subtilis probiotic improved performance through enhanced nutrient utilization and reduced excreta moisture content indicating improved pullet gut health.

Abstract
Growth performance and gastrointestinal (GIT) responses to a single-strain of Bacillus subtilis (SSB) were investigated using 960 Hybrid Converter Toms. A total of 4 iso-caloric and iso-nitrogenous corn-soybean meal-based diets were allocated to 12 replicate cages/pens and fed (ad libitum) in a four-phase feeding program (starter; days 0 to 28, grower-1; days 29 to 56, grower-2; days 57 to 84, and finisher; days 85 to 126). The diets had either 0 (control), 1E+08 (low), 2E+08 (mid) or 1E+09 (high) cfu B. subtilis/kg. Feed intake (FI) and BW were recorded by phase. Excreta samples were collected towards the end of starter and grower-1 phases for apparent retention (AR) of components by marker method and litter moisture, respectively. Selected birds were necropsied on days 28 and 56 for GIT weight and samples for jejunal histomorphology and ceca digesta short chain fatty acids (SCFA). Supplemental SSB had linear and non-linear (P < 0.05) response on BW gain (BWG). Specifically, relative to the control, birds fed low SSB had higher BWG in starter and grower-1 phases whereas bird fed mid and high SSB had lower BWG in grower-2 and birds fed low and mid SSB had higher BWG in finisher phase. Consequently, birds fed low and mid SSB doses were heavier (P < 0.05) than control fed birds at the end of trial. The FCR response to SSB was linear and non-linear (P < 0.05) with birds fed low SSB showing lower FCR than control fed birds in starter, grower-1 and finisher phases. Supplemental SSB had linear and non-linear (P < 0.05) effects on AR of components (DM, ash, crude protein, crude fat, neutral detergent fiber, and gross energy), litter moisture, GIT weight, jejunal histomorphology, and SCFA. Relative to control, birds fed high SSB showed higher AR of components, villi height, day 56 ceca digesta total SCFA concentration, and lower litter moisture. In conclusions, under condition of the current study, growth performance was optimized by low to mid SSB. Improved nutrient retention and indices of gut health suggested higher SSB doses may optimize growth performance under challenging farm conditions.

Vertical electrical impedance (VEI) testing is a method that was developed specifically for quantifying the level of protection against chloride ingress in concrete bridge decks. A significant operational difficulty associated with VEI testing has been establishing the required rebar tap as a ground reference. As described in this work, the use of a large-area electrode (LAE) can potentially remove the need for a rebar tap and therefore significantly simplify and accelerate the VEI testing process. The specific objective of the research was to develop both theoretical and practical guidance for the design of an LAE for VEI testing. To investigate several variables that can affect the accuracy of VEI measurements obtained using an LAE connection, including various combinations of deck cover and water resistivity values, electrode separation distance, counter electrode (CE) effective area, and area ratio between the LAE and the CE, an analytical model (AM) and a finite-element model (FEM) were developed and validated with laboratory and field experiments. From the results of the AM and FEM simulations and the results of the laboratory and field experiments, LAE design considerations were developed for each of these variables that should allow proper implementation of a VEI measurement system using an LAE connection.

Abstract
This study uses conversation analysis to explore 'candidate obstacles', a practice observed in sequences of patient resistance to lifestyle advice within health professional consultations. This article presents illustrative analyses of selected data excerpts drawn from audio-visual recordings of 116 tracked consultations between health professionals and 34 patients newly diagnosed with type 2 diabetes mellitus in New Zealand. The analysis shows that in consultations where health promotion activities are central, patient resistance can provide space for patients to identify obstacles to their compliance with lifestyle advice. Identifying candidate obstacles provides opportunities for health professionals to align advice with concerns of patients and potentially improve patient outcomes.

Abstract
OBJECTIVE Family planning discussions are an important aspect of medical care for women with systemic lupus erythematosus (SLE) as active disease is a risk factor for poor pregnancy outcomes, and the medications used for treatment can be harmful to the fetus when used during conception and pregnancy. Our objective was to examine the impact of patient perception of quality and type of communication on receiving contraception counseling. METHODS Data were derived from patients enrolled in the University of California, San Francisco Lupus Outcomes Study. Individuals participate in a yearly structured telephone interview that includes assessment of contraception counseling when starting new medications, and measures of communication and decision making. Logistic regression was performed to identify predictors of not receiving contraception counseling. RESULTS Of the 68 women included in this analysis, one-third did not receive contraception counseling when starting new medications. Older age, white race, depressive symptoms, and higher SLE disease activity were independently associated with not receiving contraception counseling. Participants who did not receive contraception counseling rated their physicians lower in shared decision-making (SDM) communication. CONCLUSIONS This study demonstrates a gap in family planning counseling among women with SLE starting new medications. Future studies to address these potential areas of intervention, including education about the need for contraception through menopause, and mechanisms to engage in SDM surrounding contraception are needed to improve quality of care for women with lupus.

Abstract
Little research has been undertaken on the actual decision-making processes in cancer care multidisciplinary meetings (MDMs). This article was based on a qualitative observational study of two regional cancer treatment centers in New Zealand. We audiorecorded 10 meetings in which 106 patient cases were discussed. Members of the meetings categorized cases in varying ways, drew on a range of sources of authority, expressed different value positions, and utilized a variety of strategies to justify their actions. An important dimension of authority was encountered authority-the authority a clinician has because of meeting the patient. The MDM chairperson can play an important role in making explicit the sources of authority being drawn on and the value positions of members to provide more clarity to the decision-making process. Attending to issues of process, authority, and values in MDMs has the potential to improve cancer care decision making and ultimately, health outcomes.

Abstract
The effect of a commercial organic acid (OA) product on BW loss (BWL) during feed withdrawal and transportation, carcass yield, and meat quality was evaluated in broiler chickens. Two experiments were conducted in Brazil. Commercial houses were paired as control groups receiving regular water and treated groups receiving OA in the water. Treated birds had a reduction in BWL of 37 g in experiment 1 and 32.2 g in experiment 2. In experiment 2, no differences were observed in carcass yield between groups. Estimation of the cost benefit suggested a 1:16 ratio by using the OA. In experiment 3, conducted in Mexico, significant differences on water consumption, BWL, and meat quality characteristics were observed in chickens that were treated with the OA (P < 0.05). These data suggest this OA product may improve animal welfare and economic concerns in the poultry industry by reducing BWL and improving meat quality attributes.

Abstract
Abstract
Background: Anthracyclines are among the most effective agents in the treatment of breast cancer; however, dose-dependent cumulative cardiotoxicity limits their use. Amrubicin is a synthetic anthracycline topoisomerase II inhibitor demonstrating potent antitumor effects coupled with little potential for cardiotoxicity. We report the final results from a phase I/II trial of amrubicin as second- or third-line therapy for HER2-negative MBC.
Methods: Eligible patients (pts) included women with measurable HER2-negative MBC who had received 1 or 2 prior chemotherapy regimens for MBC. Previous anthracyclines were permitted if ≥ 6 months prior to study entry. Normal LVEF was required. Amrubicin 110 mg/m2 IV (dose established from phase I portion) was administered every 3 weeks until disease progression or intolerable toxicity; growth factor use was permitted. Disease evaluations were performed every 6 weeks and LVEF assessments every 12 weeks. Progression-free survival (PFS) was the primary endpoint; a median PFS ≥ 4.5 months would merit further evaluation of amrubicin in MBC. Toxicity, overall survival, and overall response rate (ORR) were secondary endpoints.
Results: Between 1/2010 and 3/2012, 78 pts were enrolled, and 66 pts are included in this analysis (ph I: 3 pts; ph II 63 pts). Baseline characteristics included: median age 59 years; hepatic metastases in 50%; ≥ 3 sites of metastatic disease in 32%. Triple-negative histology was noted in 27%; prior adjuvant chemotherapy in 50%; prior anthracyclines in 32%; and 2 prior cytotoxic regimens for MBC in 35%. Median treatment duration was 18 weeks (6 cycles), range 1- 24 cycles. The ORR was 21% in evaluable pts (2 CR, 10 PR); 5 of these 12 pts had prior anthracyclines. 14% were not evaluable. The clinical benefit rate (CBR) was 42% (CBR = CR+PR+SD≥ 4 months); 35% of these responders received ≥12 cycles of amrubicin. Median PFS for all pts was 4.0 months (95% CI 2.5- 5.8 months) and did not significantly differ by line of therapy administered (4.0 months as 2nd line vs 4.7 as 3rd line therapy). 36% of pts were free of progression at 6 months. Neutropenia was the most common grade 3/4 toxicity present in 42% and accompanied by fever in 7%. No grade 3/4 non-hematologic toxicity occurred in > 5% pts. One pt previously treated with anthracyclines experienced a transient 20% LVEF decline to 44% at cycle 4. This recovered to baseline within 2 weeks and pt continued to receive 2 additional cycles of amrubicin before experiencing PD. No other grade 3/4 cardiac events were noted. In 3 pts, amrubicin was discontinued due to toxicity (G4 neutropenia, G2 thrombocytopenia, G2 nausea/vomiting/vertigo).
Conclusions: Amrubicin was active and well tolerated in the second- or third-line MBC setting with manageable toxicity. The ORR of 21% and median PFS of 4 months are comparable to other single agents in this setting. The observed CBR of 42%, and the fact that nearly 1/3 of these responders received ≥12 cycles of amrubicin with no cardiotoxicity, suggests that future evaluations of amrubicin in breast cancer are warranted.

Abstract
The Falkland Islands fishing industry is unique, as 60-80% of its annual catch consists of two squid species, Illex argentinus and Doryteuthis gahi. Short annual life cycles make both species susceptible to intra-annual environmental changes, resulting in large biomass fluctuations that must be addressed in management of the stocks. In the D. gahi fishery, short chains of communication between science, management and industry allow effective cooperation in the interest of long-term sustainable exploitation. The industry is responsive to short-notice requests for in-season information about the fishery. Management takes into account both scientific advice and industry recommendations, through ongoing consultations before and during the fishing seasons. As a result of this cooperation, D. gahi is one of the best managed squid fisheries in the world with local fishing companies being amongst the largest and most profitable enterprises in the Falklands economy. The I. argentinus fishery has the same potential, but a further level of cooperative management is needed as this squid is a straddling stock between several countries and the high seas. Development of a regional fisheries management organization in the South Atlantic Ocean is required to control multilateral exploitation and ensure long-term sustainability of I. argentinus stocks.

Abstract
Abstract
Background: Sorafenib (S) is an oral multi-kinase inhibitor with effects on tumor proliferation and angiogenesis, targeting VEGFR1 and VEGFR2. It has modest activity as a single agent in breast cancer. In combination with capecitabine, S demonstrated a significant improvement of 2.3 months in progression free survival (PFS) in patients (pts) with metastatic breast cancer (MBC) and added benefit when combined with paclitaxel. Ixabepilone (Ixa) is a semi-synthetic analog of epothilone B with excellent single agent activity in MBC. The phase I portion of this trial identified the MTD of the Ixa and S combination. We now report the initial results of the phase II trial with this novel combination.
Methods: Eligibility criteria included: HER2-negative MBC previously untreated with chemotherapy; measurable disease; ECOG PS 0–2; normal LVEF; and adequate bone marrow and organ function. Prior hormonal therapy for MBC was permitted. Pts received Ixa 32mg/m2 IV on day 1 of each 21-day cycle and S 400mg PO BID. Following a minimum of 4 cycles of the combination, responding pts could discontinue Ixa and remain on study treatment with S monotherapy. Granulocyte-stimulating growth factors were permitted after cycle one. Tumor assessments were performed every 9 weeks. Pts continued study treatment until disease progression or unacceptable toxicity. The primary endpoint of this trial was PFS; the addition of S to Ixa was hypothesized to improve PFS from 4.2 month to 6.2 months in this patient population. The total enrollment goal is 85 pts, and the trial is currently open to accrual.
Results: Between 5/2010 and 4/2012, 76 pts have been enrolled, and 57 pts (56 females, 1 male) are included in this analysis. Baseline characteristics included: median age 58; 61% were ER and/or PR positive; 39% were triple-negative; 39% received neoadjuvant therapy. Anthracycline exposure was noted in 34 pts and prior taxane exposure in 39 pts. 29 pts received prior hormonal therapy, 7 of these for MBC. Sites of metastatic disease included lymph nodes 42%, lung 35%, liver 30%, bone 30%, and 23% other. 19 pts (33%) had 3 or more sites of metastatic disease. Median treatment duration was 3 cycles (9 weeks), range 1–11+ cycles with 9 pts discontinuing Ixa after a median of 6 cycles and continuing on S monotherapy. 12 pts (21%) had objective responses (1 CR, 11 PR); 3 of the 22 (14%) triple-negative patients had responses (1 CR, 2 PR). An additional 24 patients (42%) had stable disease at first reevaluation. Neutropenia was the most common grade 3/4 toxicity (26%) with growth factor use reported in 35%. Grade 3/4 non-hematologic toxicity occurring in > 5% of patients consisted of: rash (12%), fatigue (11%), hypersensitivity reaction (7%, Ixa= 3 pts and S= 1 pt), and neuropathy (7%). Discontinuation due to adverse events occurred in 11%.
Conclusion: The combination of Ixa and full dose S was well tolerated with no new observed toxicities. Adverse events were manageable and consisted primarily of G3/4 neutropenia and rash. Study is ongoing and updated results will be presented.

Abstract
AIMS To determine the proportion of cases of childhood Type 1 diabetes that present with ketoacidosis and any temporal trend. To assess the impact of a publicity campaign promoting earlier diagnosis. METHODS We used an all-Wales register of incident cases with data on 2046 children from 1991 to 2009. The proportion with ketoacidosis at diagnosis was compared with the Yorkshire Childhood Diabetes Register. On World Diabetes Day posters were sent to every pharmacy, school and general practitioner surgery across Wales and radio interviews given. A questionnaire survey was conducted in Gwent to assess penetrance of the campaign. RESULTS Annually, in 1991-2009 the proportion presenting with ketoacidosis varied between 20% and 33% (mean 25%) with no change over time. Similar proportions occurred in Yorkshire. Ketoacidosis was more common before age 5 years (37% of cases) than at age 5-9 years (20%) or 10-14 years (23%) (P < 0.001). From November 2006-2007 30% of cases presented with ketoacidosis and from November 2007-2008 25% cases presented with ketoacidosis. After the campaign (November 2008-2009) 26% presented with ketoacidosis (P = 0.72). The information had reached a low proportion of families. General practitioners referred immediately cases that presented to them. CONCLUSIONS Over 20 years in Wales there has been no change in the proportion of children with Type 1 diabetes initially presenting with ketoacidosis. This presentation occurs in a higher proportion of new cases aged under 5 years. Publicity to increase awareness did not reduce the proportion with ketoacidosis at diagnosis in Wales. We need to get the educational message through to parents to reduce ketoacidosis at presentation.

Abstract
Abstract
Background: Angiogenesis plays a substantial role in breast cancer development as well as in triple negative breast cancer (TNBC). Sunitinib is an inhibitor of the tyrosine kinase receptors for VEGF, platelet-derived growth factor (PDGF), KIT, RET, and fms-like tyrosine kinase receptor-3 (FLT3). As monotherapy in heavily pretreated breast cancer patients (pts), sunitinib demonstrated a response rate of 15% in TNBC (11% of all pts) with stable disease or better in 16% of all pts. The combination of paclitaxel and carboplatin is ideally suited for further exploration as neoadjuvant chemotherapy for TNBC, based on the established preclinical and clinical sensitivity of TNBC to these cytotoxic agents. This open label, phase I/II trial was designed to evaluate the combination of sunitinib plus paclitaxel and carboplatin as neoadjuvant treatment for locally advanced breast cancer. The primary objective for the phase I portion was to determine the maximum tolerated dose (MTD); these results are presented. Methods: Women with histologically confirmed invasive triple-negative adenocarcinoma of the breast, (defined as <10% staining by IHC for ER/PR; IHC 0–1+ or FISH negative for HER2), with no evidence of metastatic disease and normal LVEF were eligible. All pts received sunitinib (days 1–28), paclitaxel (days 1, 8, 15), and carboplatin (day 1) in 28-day treatment cycles x6. Following 6 cycles, pts had definitive surgery. After ≥2 weeks and evidence of adequate wound healing, maintenance sunitinib 25mg PO daily was initiated to complete a total of 52 weeks. Three dose levels were evaluated as shown in the table below:
Doses were escalated in sequential cohorts of pts using standard phase I methodology. MTD was defined as the highest dose level (DL) producing ≤1 dose limiting toxicities (DLTs) in a pt cohort. The MTD identified in the phase I portion of the study will be used in the phase II portion, which will evaluate the efficacy, safety, and tolerability of this combination in pts with locally advanced TNBC.
Results: 15 women with TNBC were enrolled between 10/2009 and 2/2011 [median age 53 years (range: 40–78)]. Due to grade 3 neutropenia resulting in the inability to deliver cycle 1 day 15 paclitaxel in the first pt treated at both DLs 1 and 2, these DLs were expanded to 6 pts each. No additional cycle 1 DLTs were noted in the 5 additional pts at either DL. Three pts were accrued to DL 3; there were 2 DLTs noted among these pts (grade 3 febrile neutropenia; grade 3 neutropenia with cycle 2 day 1 treatment delay). However, due to the development of grade 3/4 neutropenia in subsequent cycles in 5 of 6 DL 2 pts, resulting in dose delays and requiring dose reductions, the MTD of this combination was defined as DL 1 (paclitaxel 70mg/m2 (Days 1, 8, 15); carboplatin AUC=5 (Day 1); sunitinib 25mg PO daily).
Conclusions: The administration of sunitinib with paclitaxel plus carboplatin as neoadjuvant therapy is feasible with neutropenia defining the MTD of this combination. The phase II portion of this study is ongoing.
