Abstract
Single-cell genomics has revolutionized tissue analysis by revealing the genetic program of individual cells. The key aspect of the technology is the use of barcoded beads to unambiguously tag sequences originating from a single cell. The generation of unique barcodes on beads is mainly achieved by split-pooling methods, which are labor-intensive due to repeated washing steps. Towards the automation of the split-pooling method, we developed a simple method to magnetize hydrogel beads. We show that these hydrogel beads provide increased yields and washing efficiencies for purification procedures. They are also fully compatible with single-cell sequencing using the BAG-Seq workflow. Our work opens the automation of the split-pooling technique, which will improve single-cell genomic workflows.

Abstract
BACKGROUND Avascular osteonecrosis of the femoral head (AVN) often results in total hip arthroplasty (THA). The cause for increased THA revision rates among patients with AVN is not yet fully understood. PURPOSE To perform a comparative radiological analysis of implant integration between patients with AVN and osteoarthritis (OA). MATERIAL AND METHODS After a matched pair analysis of 58 patients, 30 received THA due to OA, 28 due to AVN. X-ray images were evaluated after one week ("baseline") and on average 37.58 months postoperatively ("endline"). The prosthesis was grouped into 10 regions of interest (ROI): seven femoral and three acetabular. Incidence, width, and extent of "radiolucent lines" were measured within each zone. RESULTS Between baseline and endline, width and extent progressed more noticeably in all femoral and acetabular zones among patients with AVN. In femoral ROI 1, the width increased in 40% of AVN cases compared to 6.7% of OA cases. For acetabular ROI 3, the width increased in 26.7% of AVN cases compared to no perceived changes in the OA group. No signs of prosthetic loosening were found in the AVN group. CONCLUSION The increase of width and extent of radiolucent lines over time in patients with AVN could be a sign of lack of osteointegration. However, prosthetic loosening in absence of clinical symptoms cannot be deduced from radiological findings after medium-term postoperative follow-up. Further long-term studies are required to monitor how radiolucent lines develop in respect to long-term implant loosening. Dependent on bone quality, individually adapted reaming and broaching of the implant site are recommended.

Intraoperative control by Schanz-screws is inaccurate to achieve the exact amount of correction in de-rotational osteotomies. Knee Surg Sports Traumatol Arthrosc 2023; 31:4319-4326. [PMID: 37329368 DOI: 10.1007/s00167-023-07485-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/01/2023] [Accepted: 06/06/2023] [Indexed: 06/19/2023]
Abstract
PURPOSE The accuracy of intraoperative control of correction commonly is achieved by K-wires or Schanz-screws in combination with goniometer in de-rotational osteotomies. The purpose of this study is to investigate the accuracy of intraoperative torsional control in de-rotational femoral and tibial osteotomies. It is hypothesized, that intraoperative control by Schanz-screws and goniometer in de-rotational osteotomies around the knee is a safe and well predictable method to control the surgical torsional correction intraoperatively. METHODS 55 consecutive osteotomies around the knee joint were registered, 28 femoral and 27 tibial. The indication for osteotomy was femoral or tibial torsional deformity with the clinical occurrence of patellofemoral maltracking or PFI. Pre- and postoperative torsions were measured according to the method of Waidelich on computed tomography (CT) scan. The scheduled value of torsional correction was defined by the surgeon preoperatively. Intraoperative control of torsional correction was achieved by 5 mm-Schanz-screws and goniometer. The measured values of torsional CT scan were compared to the preoperative defined and intended values and deviation was calculated separately for femoral and tibial osteotomies. RESULTS The surgeon's intraoperative measured mean value of correction in all osteotomies was 15.2° (SD 4.6; range 10-27), whereas the postoperatively measured mean value on CT scan was 15.6 (6.8; 5.0-28.5). Intraoperatively the femoral mean value measured 17.9° (4.9; 10-27) and 12.4° (1.9; 10-15) for the tibia. Postoperatively the mean value for femoral correction was 19.8 (5.5; 9.0-28.5) and 11.3 (5.0; 5.0-26.0) for tibial correction. When considering a deviation of plus or minus 3° to be acceptable femorally 15 osteotomies (53.6%) and tibially 14 osteotomies (51.9%) fell within these limits. Nine femoral cases (32.1.%) were overcorrected, four cases undercorrected (14.3%). Four tibial cases of overcorrection (14.8%) and 9 tibial cases of undercorrection (33.3%) were observed. However, the observed difference between femur and tibia regarding the distribution of cases between the three groups did not reach significance. Moreover, there was no correlation between the extent of correction and the deviation from the intended result. CONCLUSION The use of Schanz-screws and goniometer in de-rotational osteotomies as an intraoperative control of correction is an inaccurate method. Every surgeon performing derotational osteotomies must consider this and include postoperative torsional measurement in his postoperative algorithm until new tools or devices are available to guarantee a better intraoperative accuracy of torsional correction.

Abstract
BACKGROUND AND PURPOSE CSF-venous fistula can be diagnosed with multiple myelographic techniques; however, no prior work has characterized the time to contrast opacification and the duration of visualization. The purpose of our study was to evaluate the temporal characteristics of CSF-venous fistula on digital subtraction myelography. MATERIALS AND METHODS We reviewed the digital subtraction myelography images of 26 patients with CSF-venous fistulas. We evaluated how long the CSF-venous fistula took to opacify after contrast reached the spinal level of interest and how long it remained opacified. Patient demographics, CSF-venous fistula treatment, brain MR imaging findings, CSF-venous fistula spinal level, and CSF-venous fistula laterality were recorded. RESULTS Eight of the 26 CSF-venous fistulas were seen on both the upper- and lower-FOV digital subtraction myelography, for a total of 34 CSF-venous fistula views evaluated on digital subtraction myelography. The mean time to appearance was 9.1 seconds (range, 0-30 seconds). Twenty-two (84.6%) of the CSF-venous fistulas were on the right. The highest fistula level was C7, while the lowest was T13 (13 rib-bearing vertebral bodies). The most common CSF-venous fistula levels were T6 (4 patients) followed by T8, T10, and T11 (3 patients each). The mean age was 58.3 years (range, 31.7-87.6 years). Sixteen patients were women (61.5%). CONCLUSIONS This is the first study to report the temporal characteristics of CSF-venous fistulas using digital subtraction myelography. We found that on average, the CSF-venous fistula appeared 9.1 seconds (range, 0-30 seconds) after intrathecal contrast reached the spinal level.

Testosterone suppression plus enzalutamide versus testosterone suppression plus standard antiandrogen therapy for metastatic hormone-sensitive prostate cancer (ENZAMET): an international, open-label, randomised, phase 3 trial. Lancet Oncol 2023; 24:323-334. [PMID: 36990608 DOI: 10.1016/s1470-2045(23)00063-3] [Citation(s) in RCA: 29] [Impact Index Per Article: 29.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2022] [Revised: 02/05/2023] [Accepted: 02/06/2023] [Indexed: 03/29/2023]
Abstract
BACKGROUND The interim analysis of the ENZAMET trial of testosterone suppression plus either enzalutamide or standard nonsteroidal antiandrogen therapy showed an early overall survival benefit with enzalutamide. Here, we report the planned primary overall survival analysis, with the aim of defining the benefit of enzalutamide treatment in different prognostic subgroups (synchronous and metachronous high-volume or low-volume disease) and in those who received concurrent docetaxel. METHODS ENZAMET is an international, open-label, randomised, phase 3 trial conducted at 83 sites (including clinics, hospitals, and university centres) in Australia, Canada, Ireland, New Zealand, the UK, and the USA. Eligible participants were males aged 18 years or older with metastatic, hormone-sensitive prostate adenocarcinoma evident on CT or bone scanning with 99mTc and an Eastern Cooperative Oncology Group performance status score of 0-2. Participants were randomly assigned (1:1), using a centralised web-based system and stratified by volume of disease, planned use of concurrent docetaxel and bone antiresorptive therapy, comorbidities, and study site, to receive testosterone suppression plus oral enzalutamide (160 mg once per day) or a weaker standard oral non-steroidal antiandrogen (bicalutamide, nilutamide, or flutamide; control group) until clinical disease progression or prohibitive toxicity. Testosterone suppression was allowed up to 12 weeks before randomisation and for up to 24 months as adjuvant therapy. Concurrent docetaxel (75 mg/m2 intravenously) was allowed for up to six cycles once every 3 weeks, at the discretion of participants and physicians. The primary endpoint was overall survival in the intention-to-treat population. This planned analysis was triggered by reaching 470 deaths. This study is registered with ClinicalTrials.gov, NCT02446405, ANZCTR, ACTRN12614000110684, and EudraCT, 2014-003190-42. FINDINGS Between March 31, 2014, and March 24, 2017, 1125 participants were randomly assigned to receive non-steroidal antiandrogen (n=562; control group) or enzalutamide (n=563). The median age was 69 years (IQR 63-74). This analysis was triggered on Jan 19, 2022, and an updated survival status identified a total of 476 (42%) deaths. After a median follow-up of 68 months (IQR 67-69), the median overall survival was not reached (hazard ratio 0·70 [95% CI 0·58-0·84]; p<0·0001), with 5-year overall survival of 57% (0·53-0·61) in the control group and 67% (0·63-0·70) in the enzalutamide group. Overall survival benefits with enzalutamide were consistent across predefined prognostic subgroups and planned use of concurrent docetaxel. The most common grade 3-4 adverse events were febrile neutropenia associated with docetaxel use (33 [6%] of 558 in the control group vs 37 [6%] of 563 in the enzalutamide group), fatigue (four [1%] vs 33 [6%]), and hypertension (31 [6%] vs 59 [10%]). The incidence of grade 1-3 memory impairment was 25 (4%) versus 75 (13%). No deaths were attributed to study treatment. INTERPRETATION The addition of enzalutamide to standard of care showed sustained improvement in overall survival for patients with metastatic hormone-sensitive prostate cancer and should be considered as a treatment option for eligible patients.

Abstract
Background: Women with triple-negative breast cancer (TNBC) with residual disease after neoadjuvant chemotherapy (NACT) or hormone-receptor (HR)-positive/HER2-negative breast cancer (BC) with a CPS (clinical and post treatment pathological stage) +EG (estrogen receptor status and grade) score ≥3 or score 2 and nodal involvement after NACT (ypN+) are at high risk of recurrence. SG is approved by the Food and Drug Administration for the treatment of patients with metastatic TNBC who received at least two prior therapies for metastatic disease and has shown activity in heavily pretreated patients with metastatic HR-positive/HER2-negative BC. SG may represent a new option against residual disease after NACT. Trial Design: SASCIA is a phase III, prospective, international, multicenter, randomized, open label, parallel group study (NCT04595565) of the GBG in collaboration with the AGO-B. Eligible patients must have received taxane-based NACT for 16 weeks, including 6 weeks of a taxane. Patients should have centrally confirmed HER2-negative BC (IHC score 0-1 or FISH negative) and either HR-negative (<1%), with any residual invasive disease > ypT1mi or HR-positive (≥1%), with a CPS+EG score ≥3 or CPS+EG score 2 and ypN+ using local ER and grade assessed on core biopsies taken before NACT. Radiotherapy should be delivered before study treatment start. Patients are randomized 1:1 to receive either SG 10 mg/kg body weight (days 1, 8 q3w for eight cycles) or treatment of physician´s choice (capecitabine 2000 mg/m² day 1-14 q21 or platinum-based chemotherapy i.e. carboplatin AUC 5 q3w or AUC 1.5 weekly for eight 3 weekly cycles or observation). Randomization is stratified by HR status (positive, negative) and nodal involvement after NACT (ypN+, ypN0). Endocrine-based therapy will be administered according to local guidelines in patients with HR-positive BC. The primary endpoint is invasive disease-free survival (iDFS). Secondary endpoints include comparison of overall survival (OS, key secondary endpoint), distant disease-free survival, locoregional recurrences-free interval, safety, compliance, iDFS and OS according to stratified and - predefined subgroups, patient reported outcome, and quality of life between treatment arms. As of 21st June 2021, 57/1200 patients have been randomized in Germany.

Abstract
Gamma-ray bursts (GRBs), which are bright flashes of gamma rays from extragalactic sources followed by fading afterglow emission, are associated with stellar core collapse events. We report the detection of very-high-energy (VHE) gamma rays from the afterglow of GRB 190829A, between 4 and 56 hours after the trigger, using the High Energy Stereoscopic System (H.E.S.S.). The low luminosity and redshift of GRB 190829A reduce both internal and external absorption, allowing determination of its intrinsic energy spectrum. Between energies of 0.18 and 3.3 tera-electron volts, this spectrum is described by a power law with photon index of 2.07 ± 0.09, similar to the x-ray spectrum. The x-ray and VHE gamma-ray light curves also show similar decay profiles. These similar characteristics in the x-ray and gamma-ray bands challenge GRB afterglow emission scenarios.

Abstract
INTRODUCTION Lung cancer is the most common cancer diagnosed worldwide. Data from several studies fall short to make appropriate conclusions on the management for elderly patients. The discovery of targeted therapy and immunotherapy has allowed these patients access to a wider array of options. AREAS COVERED The authors review research for treating older patients with lung cancer focusing on research performed in this patient population. Data are presented relating to chemotherapy, immunotherapy, and targeted therapy in the advanced setting. EXPERT OPINION Elderly patients particularly benefit from advances in systemic therapy. Based on the tumor profile, treatment with targeted therapy or immunotherapy should be favored over chemotherapy where possible in the elderly population. Elderly patients benefit from EGFR, ALK, and ROS-1 inhibition in the setting of these tumor alterations. These agents should be utilized early in the treatment course. Across many studies, the benefit from immunotherapy is seen irrespective of age. Favorable outcomes and toxicity profiles from immunotherapy compared to chemotherapy are well described. Chemotherapy should be offered with caution after a detailed assessment. Options include combination or single-agent chemotherapy regimens. Best supportive care alone is a reasonable option in the frailer, highly co-morbid patient.

Abstract
Abstract
We performed a large-scale profiling of currently available kinase inhibitors (KI) to identify “off-targets” that could be repurposed/repositioned as the starting point for the rational development of novel and selective kinase inhibitors against underdrugged targets. We profiled 257 KI at a single dose against a panel of 365 wild-type kinases tested individually, for a total of about 100,000 in vitro drug/kinase data points. After unsupervised hierarchical clustering of this dataset based on percent inhibition values, we identified a well-resolved subcluster driven by 5 KI with limited polypharmacology and a clean kinase-inhibition profile, mostly targeting AGC group kinases. These inhibitors were the AKT inhibitors GSK-690693, AZD-5363, and AT-7867; the MSK inhibitor SB-747651-A; and the Rho kinases (ROCK) inhibitor GSK-269962A. Notably, the AGC and hippo kinases LATS1 and LATS2 were part of this subcluster and were both inhibited to significant extents by these 5 compounds. With the regenerative potential of a candidate LATS1/2 inhibitor in mind, we next developed several orthogonal biochemical and cellular assays to prioritize compounds that possessed the desired activity against LATS1/2 without the burden of cytotoxic “off-targets,” such as those resulting from strong AKT inhibition. Based on the results of these assays, we prioritized one of the initially identified kinase inhibitors as the starting point for an ongoing, rational structure-activity relationship (SAR) effort to develop novel, 1st-in-class, highly selective LATS1 and LATS2 inhibitors. We will present data showing how such novel LATS1/2 inhibitors efficiently block LATS1/2-dependent YAP phosphorylation, induce YAP nuclear translocation in a high cell-density setting, and promote the transcription of bona fide YAP target genes such as AMOTL2, CTGF, and CYR61. Finally, consistently with the activation of a YAP-dependent transcriptional program, small-molecule inhibitors of LATS1/2 kinases promoted proliferation/regeneration in an in vitro wound-healing assay. Altogether, we identified novel small molecules that can be used as chemical probes to acutely inactivate the Hippo signaling pathway and validated LATS1 and LATS2 kinases as novel druggable kinases whose inhibition could be exploited for several indications, spanning from regenerative medicine to cancer immunotherapy.

Abstract
Abstract
BACKGROUND
While the treatment of primary Glioblastoma Multiforme (GBM) is well defined, the role of surgical resection in recurrent GBM is not firmly established.1 Treatment options for recurrent GBM include second-line chemotherapy, re-irradiation and surgical re-resection.2 This review examines current practice in a national neuro-oncology centre. AIMS: To investigate survival outcomes in patients undergoing surgical re-resection for recurrent GBM in our institution and to compare our findings to the relevant published literature.
METHODS
A retrospective review of our institution’s neuro-oncology database was performed. We evaluated all patients who underwent re-resection for recurrent GBM following standard adjuvant treatment between 2015–2018. Patients who did not have an initial diagnosis of Grade 4 GBM and patients who were re-operated on within one month were excluded. We analysed overall survival using Kaplan Meier curves. Patients not known to have died were censored to the last known alive date. We also examined factors which may affect patient outcome, including age, sex, extent of resection, tumour characteristics and tumour location.
RESULTS
34 patients were eligible for inclusion into this study, of these 21 (61%) were male. Median age was 52. A radiologically confirmed initial resection of > 80% was achieved in 52% of patients. Median time from initial surgery to re-resection was 13.5 months. Median survival from initial surgery was 28.6 months and median survival after re-resection was 9.5 months.
CONCLUSION
Re-operation appears to have a role in the management of recurrent GBM in carefully selected cases. Overall survival in this patient cohort remains poor and further studies into the benefit of re-resection in comparison to second-line chemotherapy and re-irradiation would be of value.

Abstract
Desmoplastic infantile tumors are rare supratentorial brain tumors that occur in pediatric patients. Desmoplastic infantile tumors are made up of 2 subtypes: desmoplastic infantile gangliogliomas and desmoplastic infantile astrocytomas. Desmoplastic infantile tumors are often identifiable on imaging on the basis of multiple characteristics. Nevertheless, pathologic analysis is required to confirm the diagnosis, particularly when the imaging features are atypical. Here, the radiology findings, surgical approach and subsequent management, and pathology of a desmoplastic infantile ganglioglioma are described.

Bioelectrical impedance analysis (BIA)-derived phase angle (PA) is a practical aid to nutritional assessment in hospital in-patients. Clin Nutr 2018; 38:1700-1706.

Abstract
BACKGROUND Nutritional status can be difficult to assess. Bioelectrical impedance analysis (BIA)-derived phase angle (PA), and the plasma markers citrulline and transthyretin (pre-albumin) have the potential to assist, but the protocol of fasting and resting for BIA renders the investigation impractical for routine use, especially so in populations at high risk of malnutrition. AIMS 1 To clarify whether starving and resting are necessary for reliable measurement of PA. 2 To identify whether PA, citrulline and transthyretin correlate with nutritional status. METHODS Eighty consenting adult in-patients were recruited. Nutritional status was determined by subjective global assessment (SGA) used as gold standard. The Malnutrition Universal Screening Tool (MUST) was used and anthropometric measurements were performed. Serum was analysed for citrulline and transthyretin. PA was measured using Bodystat 4000. The PA was considered to define malnutrition when lower than reference ranges for sex and age, and severe malnutrition if more than 2 integers below the lower limit. Anthropometric measurements were categorised according to WHO reference centiles. Ordinal logistic regression estimated the strength of association of PA, citrulline and transthyretin with SGA. PA values in the different metabolic states were compared using paired t tests. RESULTS All 80 subjects completed the BIA and the nutritional assessments in the 3 different states; 14 declined to provide blood samples for the biochemical assays. Malnutrition was identified in 32 cases, severe malnutrition in 14 cases, the remaining 34 cases were deemed not to be malnourished. PA was strongly inversely associated with SGA (Odds Ratio [OR] per unit increase = 0.21, CI 0.12-0.37, p < 0.001). PA was not influenced by exercise (p = 0.134) or food intake (p = 0.184). Transthyretin was inversely associated with malnourished/severely malnourished states (OR = 0.98, 95% CI 0.97-0.99, p = 0.001), but had poorer predictive values than PA. There was no significant association between citrulline concentration and SGA (OR = 1.01, 95% CI 0.99-1.04, p = 0.348). CONCLUSIONS The BIA-derived PA reliably identifies malnutrition. It is strongly associated with SGA but requires less skill and experience, and out-performs circulating transthyretin, rendering it a promising and less operator-dependent tool for assessing nutritional status in hospital patients. Our novel demonstration that fasting and bed-rest are unnecessary consolidates that position.

Frequency, impact and a preclinical study of novel ERBB gene family mutations in HER2-positive breast cancer. Ther Adv Med Oncol 2018; 10:1758835918778297. [PMID: 30023006 PMCID: PMC6047239 DOI: 10.1177/1758835918778297] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/19/2017] [Accepted: 03/22/2018] [Indexed: 12/27/2022] Open
Abstract
Background: Somatic mutations in the ERBB genes (epidermal growth factor
receptor: EGFR, ERBB2, ERBB3, ERBB4) promote oncogenesis
and lapatinib resistance in metastatic HER2+ (human epidermal growth
factor-like receptor 2) breast cancer in vitro. Our study
aimed to determine the frequency of mutations in four genes: EGFR,
ERBB2, ERBB3 and ERBB4 and to investigate
whether these mutations affect cellular behaviour and therapy response
in vitro and outcomes after adjuvant trastuzumab-based
therapy in clinical samples. Methods: We performed Agena MassArray analysis of 227 HER2+ breast cancer samples to
identify the type and frequency of ERBB family mutations.
Of these, two mutations, the somatic mutations ERBB4-V721I
and ERBB4-S303F, were stably transfected into HCC1954
(PIK3CA mutant), HCC1569 (PIK3CA wildtype) and BT474 (PIK3CA mutant, ER
positive) HER2+ breast cancer cell lines for functional in
vitro experiments. Results: A total of 12 somatic, likely deleterious mutations in the kinase and
furin-like domains of the ERBB genes (3
EGFR, 1 ERBB2, 3
ERBB3, 5 ERBB4) were identified in 7%
of HER2+ breast cancers, with ERBB4 the most frequently
mutated gene. The ERBB4-V721I kinase domain mutation
significantly increased 3D-colony formation in 3/3 cell lines, whereas
ERBB4-S303F did not increase growth rate or 3D colony
formation in vitro. ERBB4-V721I sensitized HCC1569 cells
(PIK3CA wildtype) to the pan class I PI3K inhibitor copanlisib but increased
resistance to the pan-HER family inhibitor afatinib. The combinations of
copanlisib with trastuzumab, lapatinib, or afatinib remained synergistic
regardless of ERBB4-V721I or ERBB4-S303F
mutation status. Conclusions: ERBB gene family mutations, which are present in 7% of our
HER2+ breast cancer cohort, may have the potential to alter cellular
behaviour and the efficacy of HER- and PI3K-inhibition.

Abstract
INTRODUCTION While diagnostic algorithm using PF4-heparin enzyme-linked immunosorbent assay (ELISA) optical density (OD), and heparin neutralization assay (HNA), or 4T score have been proposed to replace serotonin-release assay (SRA) for heparin-induced thrombocytopenia (HIT), their performance against SRA is unclear. In this study, we proposed and validated the performance of a new algorithm combining PF4-heparin ELISA optical density (OD), HNA and 4T score against SRA for HIT diagnosis. METHODS Heparin neutralization assays were performed on specimens submitted for HIT testing with positive PF4-heparin ELISA from December 2015 to September 2017, which were separated into a "training" and a "validation" data set. 4T scores were calculated for ELISA positive cases. RESULTS A total of 123 consecutive unique patient samples had positive PF4-heparin ELISA with also HNA data, SRA data, and 4T scores available. Compared to SRA, a "laboratory criteria" (ELISA OD ≥ 1.4 and HNA ≥ 70%) had a sensitivity of 88% (14/16) and specificity of 91% (42/46), and a "combined criteria" (4T score = 8, or 4T score = 6 or 7 and ELISA OD ≥ 1.0, or 4T score = 4 or 5 and ELISA OD ≥ 2.0) had a sensitivity of 75% (12/16) and specificity of 98% (45/46) in the training data set. Laboratory and combined criteria had 90% (56/62) concordance rate. Importantly, for these concordant cases, the diagnostic specificity is 100% (46/46). Based on the data, a novel diagnostic algorithm combining these 2 criteria was proposed and validated prospectively. CONCLUSION A novel algorithm has high diagnostic accuracy and potentially could eliminate the need for SRA testing in at least 90% patients with suspected HIT.

Abstract
Serological surveillance testing for bovine brucellosis, Enzootic Bovine Leukosis, and Warble fly reaches approximately 1.7 million tests every year in the UK. An automated system was developed to improve the quality of data handling for all three surveys. The objectives were to make improvements in efficiency, sample tracking, and test reporting and to develop an epidemiological database. The developed system of bar-coded samples and test plates processed on automated equipment capable of scanning barcodes and transferring information across a computer network met the data objectives. Consolidating and automating the highly repetitive liquid-handling steps met the cost objectives. To reduce the impact of temporary bottlenecks in the system, a philosophy of ‘islands of automation’ was adopted to maximize the throughput. The creation of this system was driven largely by the need to have in place an effective emergency response capability to handle the serological needs of an outbreak of an acute and highly infectious veterinary disease such as Foot and Mouth Disease (FMD) in the UK.

Abstract
Abstract
Background: The combination of the anthracycline, doxorubicin with cyclophosphamide (AC) is a widely used chemotherapy regimen in early stage breast cancer. Studies have shown that dose dense chemotherapy (incorporating AC) improved both disease-free survival and overall survival compared to once every 3 week treatment with daily subcutaneous G-CSF support. An important advance in the use of dose dense chemotherapy regimens was the development of pegylated forms of G-CSF, which offered the convenience of a single subcutaneous injection, rather than multiple daily injections. Lipegfilgrastim is a pegylated long-acting covalent conjugate of filgrastim (G-CSF). In a pivotal randomised phase III study in breast cancer lipegfilgrastim was shown to be non-inferior to pegfilgrastim. Although lipegfilgrastim is licensed in Europe and can facilitate every 2 week (dose dense) scheduling of chemotherapy there are a lack of prospective data about its efficacy in this setting. In this prospective, non-interventional, study we are investigating the incidence of treatment-related neutropaenia following four cycles of dose dense AC with lipegfilgrastim support.
Methods: The primary end point of this prospective, single arm study is to determine the incidence of treatment-related neutropaenia, defined as an absolute neutrophil count (ANC) of <1.0 x 109/L, following four cycles of dose dense AC with lipegfilgrastim support. The secondary end points are to (1) determine the incidence of febrile neutropaenia, defined as temperature > 38°C and ANC <1.0 x 109/L, during 4 cycles of dose dense AC with lipegfilgrastim and (2) examine the incidence of treatment-related neutropaenia during subsequent intravenous chemotherapy post completion of AC. Eligibility criteria include, patients with stage I-III breast cancer, planned treatment with dose dense AC in the adjuvant or neoadjuvant setting, age ≥ 18 years, Eastern Cooperative Oncology Group (ECOG) Performance Status 0-1 and adequate bone marrow function. Patients with prior exposure to chemotherapy and/or G-CSF, who are pregnant, have a cardiac or other concurrent illness, which at the investigator's discretion contraindicates the use of AC will be excluded. We will enrol 40 consecutive patients who are planned to undergo dose dense AC. Based on previous clinical trials, we expect that the incidence of treatment-related neutropaenia will be <12%. However, it is likely that the current study will more closely resemble real-world practice and a higher incidence of treatment-related neutropaenia may be observed. This study has been approved by the Instituational Review Board and 9 patients have been consented to date. (registered with clinicaltrials.gov).

Abstract
Aldosterone is a key signaling component of the renin-angiotensin-aldosterone system and as such has been shown to contribute to cardiovascular pathology such as hypertension and heart failure. Aldosterone synthase (CYP11B2) is responsible for the final three steps of aldosterone synthesis and thus is a viable therapeutic target. A series of imidazole derived inhibitors, including clinical candidate 7n, have been identified through design and structure-activity relationship studies both in vitro and in vivo. Compound 7n was also found to be a potent inhibitor of 11β-hydroxylase (CYP11B1), which is responsible for cortisol production. Inhibition of CYP11B1 is being evaluated in the clinic for potential treatment of hypercortisol diseases such as Cushing's syndrome.

Abstract
The effect of Replens vaginal moisturiser on the tensile properties of latex rubber condoms was compared with that of baby oil, K-Y jelly, Nystan cream and Duracreme. The tensile strength and elongation at break of test pieces cut from condoms were measured after immersion in each of the test products for five minutes. The tensile properties of the latex was unaffected after treatment with Replens. K-Y jelly, Duracreme and Replens produced similar results.
