Abstract
AIM This study aims to evaluate costs associated with periprosthetic femoral fracture (PFF) treatment at a UK tertiary referral centre. METHODS This study included 128 consecutive PFFs admitted from 02/04/2014-19/05/2020. Financial data were provided by Patient Level Information and Costing Systems. Primary outcomes were median cost and margin. Secondary outcomes were length of stay, blood transfusion, critical care, 30-day readmission, 2-year local complication, 2-year systemic complication, 2-year reoperation and 30-day mortality rates. Statistical comparisons were made between treatment type. Statistical significance was set at p<0.05. RESULTS Across the cohort, median cost was £15,644.00 (IQR £11,031.00-£22,255.00) and median loss was £3757.50 (£599.20-£8296.20). The highest costs were ward stay (£3994.00, IQR £1,765.00-£7,013.00), theatre utilisation (£2962.00, IQR £0.00-£4,286.00) and overheads (£1705.10, IQR £896.70-£2432.20). Cost (£17,455.00 [IQR, £13,194.00-£23,308.00] versus £7697.00 [IQR £3871.00-£10,847.00], p<0.001) and loss (£4890.00 [IQR £1308.00-£10,009.00] versus £1882.00 [IQR £313.00-£3851.00], p = 0.02) were greater in the operative versus the nonoperative group. There was no difference in cost (£17,634.00 [IQR £12,965.00-£22,958.00] versus £17,399.00 [IQR £13,394.00-£23,404.00], p = 0.98) or loss (£5374.00 [IQR £1950.00-£10,143.00] versus £3860.00 [IQR -£95.50-£7601.00], p = 0.21) between the open reduction and internal fixation (ORIF) and revision groups. More patients required blood transfusion in the operative versus the nonoperative group (17 [17.9%] versus 0 [0.0%], p = 0.009). There was no difference in any clinical outcome between the ORIF and revision groups (p>0.05). CONCLUSION PFF treatment costs are high with inadequate reimbursement from NHS tariff. Work is needed to address this disparity and reduce hospital costs. Cost should not be used to decide between ORIF and revision surgery.

Clinically guided core biopsy and cutaneous punch biopsy in the evaluation of breast lesions: a necessary test or an obsolete skill? Ir J Med Sci 2023; 192:317-319.

Abstract
OBJECTIVE The vast majority of breast cancers are diagnosed via image-guided procedures yet despite significant advances, imaging does not identify all breast malignancies. Clinically suspicious breast lesions with normal breast imaging remain a cause for concern. The aim of this study is to determine the diagnostic value of clinical core and cutaneous punch biopsies in the diagnosis of breast malignancy in clinically suspicious lesions with normal breast imaging. METHODS All patients with suspicious clinical breast findings and normal imaging who underwent a clinical core and/or cutaneous punch biopsy from 2012 to 2019 were reviewed retrospectively. Patients with subsequent breast malignant diagnosis were analysed. RESULTS A total of 283 biopsies (166 clinical core, 117 cutaneous punch) performed over the 7-year period were included in the analysis. A total of 263/283 (93%) yielded a benign outcome. A total of 2/283 (0.7%) yielded B3 lesions (probably benign). These lesions were benign on final surgical excision. A total of 18/283 (6.3%) yielded a malignant histopathology. Sixteen out of 18 were cutaneous punch biopsies, and 2/18 were clinical core biopsies. A total of 14/18 patients presented with nipple changes, while 4/18 had a palpable area of concern. Histopathological analysis demonstrated Paget's disease of the nipple in 8/18, invasive carcinoma in 9/18 out of which two represented a recurrence of breast malignancy. Cutaneous squamous cell carcinoma was diagnosed in 1/18. CONCLUSION Clinical core and cutaneous punch biopsies remain a valuable tool in the diagnosis of breast cancer particularly in the management of clinically suspicious radiographically occult malignancies.

Abstract
Purpose The purpose of this study was to improve the diagnostic ability of the optical coherence tomography (OCT) retinal nerve fiber layer (RNFL) probability (p-) map by understanding the frequency and pattern of artifacts seen on the p-maps of healthy control (HC) eyes resembling glaucomatous damage. Methods RNFL p-maps were generated from wide-field OCT cube scans of 2 groups of HC eyes, 200 from a commercial normative group (HC-norm) and 54 from a prospective study group, as well as from 62 patient eyes, which included 32 with early glaucoma (EG). These 32 EG eyes had 24-2 mean deviation (MD) better than -6 dB and perimetric glaucoma as defined by 24-2 and 10-2 criteria. For the HC groups, "glaucoma-like" arcuates were defined as any red region near the temporal half of the disc. Results Seven percent of the 200 HC-norm and 11% of the 54 HC RNFL p-maps satisfied the definition of "glaucoma-like," as did all the patients' p-maps. The HC p-maps showed two general patterns of abnormal regions, "arcuate" and "temporal quadrant," and these patterns resembled those seen on some of the RNFL p-maps of the EG eyes. A "vertical midline" rule, which required the abnormal region to cross the vertical midline through the fovea, had a specificity of >99%, and a sensitivity of 75% for EG and 93% for moderate to advanced eyes. Conclusions Glaucoma-like artifacts on RNFL p-maps are relatively common and can masquerade as arcuate and/or widespread/temporal damage. Translational Relevance A vertical midline rule had excellent specificity. However, other OCT information is necessary to obtain high sensitivity, especially in eyes with early glaucoma.

Abstract
Abstract
Background: De novo and acquired resistance to HER2 directed therapy is frequently encountered. Upregulation of the phosphatidylinositol-3-kinase (PI3K) pathway is an important mediator of treatment resistance. This can occur through an activating mutation of the PIK3CA gene or PTEN loss. PIK3CA mutations are present in approximately 20% of HER2 positive breast cancers and as such, the PI3K pathway has emerged as an attractive target for restoring sensitivity to HER2 directed therapy. Methods: We performed a single arm, multicentre, open label Phase Ib/II trial. Patients (pts) with advanced HER2-positive breast cancer whose disease had progressed on at least 1 line of Trastuzumab/T-DM1 based treatment in the metastatic setting were eligible if they met following criteria: ECOG PS ≤ 2 and adequate organ function. Pts with treated, controlled brain metastases were permitted to enrol. Exclusion criteria included uncontrolled hypertension or diabetes mellitus. Pts on Phase IB were treated according to a 6+6 study design with a dose escalation schedule of Copanlisib IV (level 1 = 45mg, level 2 = 60mg) on Day 1, 8 and 15 of a 28-day cycle along with a fixed dose of Trastuzumab 2mg/kg weekly. Phase II treatment was the MTD (maximum tolerated dose) of Copanlisib in combination with Trastuzumab. Archival tumour tissue, voluntary biopsies and serial plasma samples were collected for genomic sequencing. Primary endpoints were MTD (Phase I) and clinical benefit rate (CBR) which was defined as complete response (CR) or partial response (PR) at any time point; or stable disease (SD) lasting at least 24 weeks (Phase II). Secondary endpoints included safety and tolerability, tumor response rate, duration of response, time to treatment failure (TTF) and progression free (PFS) and overall survival (OS). Results: Twelve pts were enrolled in Phase IB. No dose limiting toxicity was observed. The MTD was established as Copanlisib 60mg and Trastuzumab 2mg/kg. Fourteen pts were enrolled in Phase II (6 pts treated at the MTD in Phase IB were included in the final Phase II analysis resulting in a total of 20 pts). The median number of lines of prior treatment in the metastatic setting was 3 (1-8). The most common grade 3-4 toxicities encountered in the Phase Ib/II cohorts included hypertension (n=7, 27%), hyperglycaemia (n=2, 8%) and vomiting (n=2, 8%). Three pts discontinued treatment due to toxicity. The median follow-up for the Phase II cohort was 7.5 months (95% CI 6.0-14.5). PR was observed in 4 pts (20%) and SD (at any time point) was seen in 8 pts (40%). The CBR was 30% (n=6). The duration of response was 15.0 weeks (95% CI 4.9 - 16.1). The median TTF was 11.9 weeks (95% CI 7.5 - 21.1). The median PFS was 3.0 mo (95% CI 0.2 - 5.8) and OS was 14.0 mo (95% CI 5.2-22.8). At the time of analysis, 9 of 20 patients were alive. PIK3CA mutations were detectable in the archival tissue of 11 of 26 pts (42%). PIK3CA hotspot mutations (H1047R, E542K and E545K) were detectable in the plasma of all 26 pts at various points throughout treatment. Pre and post treatment biopsies of 2 pts in the Phase IB trial revealed somatic mutations in DNAH3 and TRRAP, the latter of which encodes a PI3K-like protein kinase. Targeted next generation sequencing was performed on the circulating tumour DNA of 20 pts in the Phase II cohort taken before, during and after treatment to further validate these findings and to assess for other mechanisms of response or resistance. The final translational results will be presented at the meeting. Conclusions: The combination of Copanlisib and Trastuzumab is a safe and tolerable regimen and is associated with clinical efficacy in a heavily pre-treated metastatic HER2-positive breast cancer population. Translational studies may have identified novel resistance biomarkers in this pt cohort.

Abstract
Abstract
Background
Elevation of circulating anti-angiogenic factors is pivotal in the development of the preeclampsia (PE) phenotype of incomplete vascular remodelling, hypertension and kidney dysfunction during pregnancy. Oxidative stress is explicitly linked to PE with high levels measurable in the placenta. Yet antioxidant therapy has failed, in some cases worsening pregnancy outcomes. The modulation of protein activity by reversible oxidative post-translational modifications (oxPTM) under low levels of reactive oxygen species is emerging as an important “redox-switch” mechanism in cardiovascular diseases, although oxPTM have not been investigated in the context of PE. Of significance, S-glutathionylation is a common oxPTM which reversal by glutaredoxin (Grx) is predominant in preeclamptic placenta and was associated with attenuated revascularisation and sFlt-1 elevation in mice.
Purpose
We aimed to identify the molecular basis for how S-glutathionylation reversal by Grx may contribute to pregnancy-induced vascular complications by modulating angiogenic signalling at the maternofoetal interface.
Methods
We combined physiological in vivo assessment with bioinformatics proteomic analysis and exon-level microarray to investigate the role of S-glutathionylation in the development of PE phenotype. In vitro studies using primary endothelial cells (EC) and iPS-derived trophoblasts investigated the effects of oxPTM reversal on angiogenic signalling in individual placental cell types and the functional consequences were assessed in 3D models replicating early-pregnancy events.
Results
Overexpressing Grx transgenic mice (TG) developed gestational hypertension, kidney dysfunction and elevated plasma levels of the anti-angiogenic factor sFlt-1 compared to their littermate controls (WT) during timed pregnancy. Grx-mediated oxPTM reversal in EC disrupted angiogenic sprouting and promoted anti-angiogenic signals by increasing sFlt-1:PlGF ratio and decreasing endoglin levels. The rise in sFlt-1 was associated with an isoform switch promoting sFlt-e15a over sFlt-i13. In trophoblasts, Grx overexpression inhibited migration and syncytialisation and modulated angiogenic balance in a cell type-specific manner. The sFlt1-e15a:PlGF ratio was increased in syncytiotrophoblasts and decreased in extra-villous trophoblasts, while endoglin expression was decreased in both cell types. A genome-wide exon-level profiling of TG vs WT mice placenta revealed a global alteration of alternative splicing events.
Conclusion
Grx-mediated removal of oxPTM directly disrupts placental angiogenic balance via dysregulation of sFlt-1 isoforms, which may promote the PE phenotype of impaired vascular remodelling, hypertension and kidney dysfunction during pregnancy.

Abstract
INTRODUCTION The non-invasive nature of the preoperative axillary ultrasound (AUS) fits the current trend of increasingly conservative axillary management. Recent publications suggest that early disease patients with clinically and radiologically negative axillae do not require sentinel lymph node biopsy (SLNB). This study aims to determine the true extent of axillary node disease in negative preoperative AUS patients. METHODS A 10-year breast cancer registry was reviewed to identify women with pathologically confirmed T1-2 invasive breast cancer and a negative preoperative AUS. Patients who received neoadjuvant chemotherapy were excluded. Combined positive lymph node count of SLNB ± ALND was used to determine total nodal burden (TNB). Axillae were classified into low nodal burden (LNB) defined as 1-2 positive nodes and high nodal burden (HNB) defined as ≥ 3 positive nodes. RESULTS 762 patients with negative AUS were included. There were 46.9% and 53.0% T1 and T2 tumours, respectively. 76.9% were node negative (0 LN +), 18.9% had LNB (1-2 LN +) and 4.2% had HNB (≥ 3LN +). Specifically, HNB disease was seen in 2% of T1 tumours and 6.2 % of T2 tumours with a negative AUS. In multivariate analysis, T2 strongly associated with ≥ 3 positive ALNs (OR 2.66 CI 1.09-6.51 p = 0.03) as did lymphovascular invasion (OR 3.56 CI 1.52-8.30 p = < 0.01). CONCLUSION This study shows that AUS in its current form cannot exclude HNB axillary metastasis to the extent of eliminating the need for surgical staging of the axilla. This may impact axillary local-regional recurrence and disease-free survival. We caution that a negative AUS has a rate of 4.2% of HNB. Therefore, in cases of negative AUS with a T2 tumour, we advocate continued use of SLNB.

Abstract
In June 2019 the first equine case of Hendra virus in the Hunter Valley, New South Wales, Australia was detected. An urgent human and animal health response took place, involving biosecurity measures, contact tracing, promotion of equine vaccinations and investigation of flying fox activity in the area. No human or additional animal cases occurred. Equine vaccination uptake increased by over 30-fold in the surrounding region in the three months following the case. Black flying fox and grey-headed flying fox species were detected in the Valley. The incident prompted review of Hendra virus resources at local and national levels. This event near the “horse capital of Australia”, is the southernmost known equine Hendra case. Management of the event was facilitated by interagency collaboration involving human and animal health experts. Ongoing One Health partnerships are essential for successful responses to future zoonotic events. In June 2019 the southernmost known equine case of Hendra virus was detected in the Hunter Valley, Australia. This signified an increase in potential equine and human populations at risk of infection. Interagency collaboration between animal and human health experts is essential in managing Hendra virus spillover events.

Abstract
Abstract
Background
The phosphoinositide 3 kinase (PI3K) pathway is important in the oncogenic function of HER2. Aberrent activation of PI3K is implicated in resistance to trastuzumab and other HER2-targeted therapies and is frequent, with up to 22% of HER2 positive breast cancer having a PIK3CA mutation. Copanlisib is a pan-class 1 PI3K inhibitor that shows particular activity against PI3Kα, the isoform encoded by the PIK3CA gene. Copanlisib has been shown to re-sensitise trastuzumab resistant cell lines to trastuzumab with synergism seen in some cell lines between copanlisib and HER2 targeted therapy.
Trial design
The study is a phase Ib/II open label, single arm adaptive, multi-centre trial of copanlisib in combination with trastuzumab. Eligible patients are treated with a dose escalation schedule of copanlisib IV on Days 1, 8 and 15 of a 28 day cycle with trastuzumab 2 mg/kg weekly (loading dose of 4 mg/kg in cycle 1). The phase II dose will be based on the maximum tolerated dose (MTD) established in Phase Ib. Patients are treated until radiologic or symptomatic progression, unacceptable toxicity, consent withdrawal or physician's decision.
Eligibility criteria
Eligible patients must have recurrent incurable or metastatic HER2-positive breast cancer that has progressed on at least one prior line of trastuzumab or T-DM1-based treatment regimen in this setting. Patients with treated and controlled brain metastases are eligible. Participants must have adequate organ function and ECOG PS ≤ 2. Patients recruited for the Phase II part of the study must have a PIK3CA mutation. Patients with uncontrolled arterial hypertension, uncontrolled diabetes or recent clinically serious infections are excluded.
Specific aims
The primary end point for the phase Ib part of this study is to determine the MTD for the combination. For the phase II study is anti-tumour efficacy, measured by Clinical Benefit Rate (CBR).
Secondary end points are evaluation of safety and tolerability, progression-free survival, time to treatment failure, duration of response and overall survival. Incorporated translational endpoints include examination of molecular tumor adaptation in tissue and blood. Given the role of PI3K in cellular glucose metabolism, an additional exploratory objective is to determine if quantitive reduction in metabolic signal on Positron Emission Tomography-Computed Tomography (PET-CT) is predictive of benefit from therapy.
Statistical methods
To establish the MTD, we use a modified 3+3 design where 3 additional patients will be accrued even if the first 3 patients accrued experience no dose limiting toxicities (DLT) in sequential cohorts for a planned 12 patients. To determine the CBR, a one sample exact binomial test with a one sided significance level of 5%, 19 evaluable patients will provide >80% power to detect a difference between the null hypothesis proportion of 30% for CBR versus the alternative hypothesis proportion of 65%.
Present accrual and target accrual
There are 9 patients recruited so far to the phase Ib part of this study. Target accrual is 12 and for phase II is 19 patients.

Abstract
Female adolescents are less active than male peers in certain contexts including the neighborhood. Adolescents' physical activity can be explained by interactions between environmental and psychosocial factors, but few studies have tested such interactions in relation to context-specific behaviors. This study tested interactions between neighborhood environmental and psychosocial factors in relation to adolescents' context-specific physical activity. Data were collected in 2009-11 from 910 adolescents and a parent/guardian residing in the Baltimore/Seattle regions. Measures included adolescent-reported neighborhood leisure-time physical activity (LTPA) and non-neighborhood LTPA, accelerometer-based non-school moderate-to vigorous-physical activity (MVPA), psychosocial factors, and objective and parent-perceived neighborhood environmental factors. Gender-stratified mixed effects linear models tested associations of 6 environmental and 4 psychosocial factors and their interactions in relation to each physical activity outcome. The psychosocial factors had consistent associations with the physical activity outcomes but the environmental correlates were context-specific. Decisional balance (weighing of pros and cons of physical activity) moderated the association between recreation facility density and neighborhood LTPA among females, with a negative association only among those with high decisional balance (pros outweighed cons). Decisional balance also moderated associations of neighborhood walkability with non-school MVPA among females and non-neighborhood LTPA among males, with positive associations only among those with high decisional balance. Results support context-specific ecological models of physical activity. Targeting environmental factors that may promote opportunities for physical activity in specific contexts as well as adolescent decision-making may help promote their physical activity in those contexts, potentially leading to increased overall physical activity.

Abstract
PURPOSE This study tested whether a multilevel physical activity (PA) intervention had differential effects on PA according to participants' perceptions of their neighborhood environment. DESIGN Two-group cluster randomized controlled trial. SETTING San Diego, California. SUBJECTS Analytical sample included 319 Latinas (18-65 years) from churches randomized to the following conditions: PA (n = 8 churches, n = 157 participants) or attention control (n = 8 churches, n = 162 participants). INTERVENTION Over 12 months, PA participants were offered free PA classes (6/wk), while attention control participants were offered cancer prevention workshops. MEASURES Baseline and 12-month follow-up measures included self-report and accelerometer-based moderate to vigorous physical activity (MVPA), sociodemographics, and perceived neighborhood environment variables. ANALYSIS Mixed-effects models examined each PA outcome at 12-month follow-up, adjusted for church clustering, baseline PA, and sociodemographics. We tested interactions between 7 baseline perceived environment variables and study condition. RESULTS Neighborhood esthetics was the only significant moderator of intervention effects on accelerometer-based MVPA and self-report leisure-time MVPA. Participants in the PA intervention had significantly higher PA at follow-up than attention control participants, only when participants evaluated their neighborhood esthetics favorably. CONCLUSION Perceived neighborhood esthetics appeared to maximize the effectiveness of a multilevel PA intervention among Latinas. For sustainable PA behavior change, the environments in which Latinas are encouraged to be active may need to be evaluated prior to implementing an intervention to ensure they support active lifestyles.

Abstract
Following notification of a stool sample positive for Salmonella from an inmate of a maximum security prison a concerted multidisciplinary public health response was undertaken. Lanarkshire NHS Board Health Protection Team (HPT) held one Problem Assessment Group Meeting and two Outbreak Control Team Meetings. The outbreak period spanned three weeks during which there were three confirmed and six probable cases of Salmonella enteritidis PT4 in prison inmates. The source was not identified despite thorough investigation, however the outbreak control team (OCT) was able to identify key recommendations around general hygiene, shared toilet facilities and storage of cooked food in cells. The outbreak stimulated closer working arrangements between the prison medical services and the local HPT. Co-operation during the outbreak investigation and subsequent to the OCT report facilitated both operational changes at the prison and improvements to the management of infection control across the Scottish Prison Service.

Abstract
Favorable perceptions of the built and social neighborhood environment may promote outdoor physical activity (PA). However, little is known about their independent and interactive effects on neighborhood-specific outdoor PA. We examined associations of perceived built and social neighborhood environment factors, and their interactions, with objectively-measured neighborhood outdoor moderate-to-vigorous physical activity (MVPA) among a sample of Latina women in San Diego, CA. Analyses included baseline data collected in 2011-2013 from 86 Latinas with ≥ 2 days of combined accelerometer and global positioning system data and complete survey measures. We examined objective neighborhood outdoor MVPA within 500-meter home buffers. Generalized linear mixed models examined associations of 3 perceived built (e.g., sidewalk maintenance) and 3 social environmental (e.g., safety from crime) factors with engaging in any daily neighborhood outdoor MVPA. Models tested interactions between the built and social environmental factors. Although the perceived neighborhood environmental factors were not significantly related to daily neighborhood outdoor MVPA, we found 2 significant interactions: perceived sidewalk maintenance x safety from crime (p = 0.05) and neighborhood aesthetics x neighborhood social cohesion (p = 0.03). Sidewalk maintenance was positively related to daily neighborhood outdoor MVPA only among Latinas that reported low levels of safety from crime. Neighborhood aesthetics was positively related to daily neighborhood outdoor MVPA only among Latinas with high neighborhood social cohesion. Findings suggest several built and social environmental factors interact to influence Latinas' neighborhood outdoor MVPA. Interventions are needed targeting both built and social neighborhood environmental factors favorable to outdoor PA in the neighborhood.

Abstract
This paper outlines a project that explored the feasibility, development and implementation of interactive multi-media (IMM) in a health care education setting. The project took place at Manchester College of Midwifery & Nursing over a 12-month period from September 1994- 1995. It sought to resolve a resource-driven problem that existed in a pre- registration nurse training programme relating to the teaching and facilitation of community care.

Abstract
Aims Using a systematic review, we investigated whether there is an increased risk of post-operative infection in patients who have received an intra-articular corticosteroid injection to the hip for osteoarthritis prior to total hip arthroplasty (THA). Methods Studies dealing with an intra-articular corticosteroid injection to the hip and infection following subsequent THA were identified from databases for the period between 1990 to 2013. Retrieved articles were independently assessed for their methodological quality. Results A total of nine studies met the inclusion criteria. Two recommended against a steroid injection prior to THA and seven found no risk with an injection. No prospective controlled trials were identified. Most studies were retrospective. Lack of information about the methodology was a consistent flaw. Conclusions The literature in this area is scarce and the evidence is weak. Most studies were retrospective, and confounding factors were poorly defined or not addressed. There is thus currently insufficient evidence to conclude that an intra-articular corticosteroid injection administered prior to THA increases the rate of infection. High quality, multicentre randomised trials are needed to address this issue. Cite this article: Bone Joint J 2016;98-B:1027–35.

Abstract
The German BSE crisis in early 2001 can be considered as a natural experiment with strong behavioral consequences. The present study investigated psychological and other factors associated with reduced meat consumption compared to the first months of the previous year. As expected, all types of meat, with the exception of poultry and game, were eaten less often. The effect was strongest in beef, where almost half of the sample reported reduced meat consumption. As predicted by the health belief model, perceived threat was associated with subjective vulnerability. It was not, however, strongly associated with perceived seriousness of BSE, probably due to the ubiquitous public discussion of the topic. Reduced beef consumption has three to four times more frequent in the event of subjective threat.

Abstract
Purpose
– This paper aims to examine how three different organisations integrate sustainability reporting into management control systems (MCS).
Design/methodology/approach
– A case study examination of sustainability reporting integrated into MCS in three New Zealand organisations.
Findings
– The integration of sustainability reporting into MCS holds advantages for organisations to operationalise sustainability objectives, broaden stakeholder accountability as well as intensify interactions with stakeholders, formalise organisation beliefs and improve communication of sustainability measures internally. While frameworks such as the balanced scorecard (BSC) can facilitate implementation of sustainability reporting, some organisations may choose to fully integrate the latter into their management control system.
Originality/value
– Sustainability reporting is sometimes seen as an external reporting philosophy that can be managed as a separate project. The authors show it can be integrated into MCS, either entirely or through tools such as the BSC. The authors develop a framework that may be useful in future studies to locate our case organisations.

Abstract
A ubiquitous post-translational modification observed in proteins is isomerization of aspartic acid to isoaspartic acid (isoAsp). This non-enzymatic post-translational modification occurs spontaneously in proteins and plays a role in aging, autoimmune response, cancer, neurodegeneration, and other diseases. Formation of isoAsp is also a significant issue for recombinant monoclonal antibody based protein therapeutics particularly when isomerization occurs in a complementarity-determining region due to potential impact to the clinical efficacy. Here, we present and compare three analytical methods to monitor and/or quantify isoAsp formation in a monoclonal antibody. The methods include two peptide map based technologies with quantitation from either UV integration or total ion peak areas, as well as an alternative approach using IdeS digestion to generate Fc/2 and Fab’2 regions, followed by hydrophobic interaction chromatography (HIC) to separate the population of Fab’2 containing an isoAsp. The level of isoAsp detected by the peptide map and the digested-HIC methods presented here show similar trends although sample throughput varies by method.

Abstract
The multi-BCL-2 homology domain pro-apoptotic BCL-2 family members BAK and BAX have critical roles in apoptosis. They are essential for mitochondrial outer-membrane permeabilization, leading to the release of apoptogenic factors such as cytochrome-c, which promote activation of the caspase cascade and cellular demolition. The BOK protein has extensive amino-acid sequence similarity to BAK and BAX and is expressed in diverse cell types, particularly those of the female reproductive tissues. The BOK-deficient mice have no readily discernible abnormalities, and its function therefore remains unresolved. We hypothesized that BOK may exert functions that overlap with those of BAK and/or BAX and examined this by generating Bok(-/-)Bak(-/-) and Bok(-/-)Bax(-/-) mice. Combined loss of BOK and BAK did not elicit any noticeable defects, although it remains possible that BOK and BAK have critical roles in developmental cell death that overlap with those of BAX. In most tissues examined, loss of BOK did not exacerbate the abnormalities caused by loss of BAX, such as defects in spermatogenesis or the increase in neuronal populations in the brain and retina. Notably, however, old Bok(-/-)Bax(-/-) females had abnormally increased numbers of oocytes from different stages of development, indicating that BOK may have a pro-apoptotic function overlapping with that of BAX in age-related follicular atresia.

Abstract
Previous research has found that poster prompts are associated with significant increases in stair use. The present study examined the use of messages on the stair risers, as an alternative to posters, to encourage stair climbing. Observers monitored shoppers' stair and escalator use over a 2-week baseline and 6-week intervention period. The prevalence of stair use increased from a baseline value of 8.1 percent to 18.3 percent when the motivating messages were in place. This increase is greater than that found in studies that used poster prompts in shopping centre venues. The apparent advantage of stair-riser banners is discussed in terms of their visibility and attractiveness, as well as their capacity to present multiple messages likely to appeal to a broader constituency. It is concluded that promoters of physical activity should use colourful, tailored stair-riser banners, rather than posters, to encourage stair climbing.

Abstract
Novel acetone and aldimine covalent adducts were identified on the N-termini and lysine side chains of recombinant monoclonal antibodies. Photochemical degradation of citrate buffers, in the presence of trace levels of iron, is demonstrated as the source of these modifications. The link between degradation of citrate and the observed protein modifications was conclusively established by tracking the citrate decomposition products and protein adducts resulting from photochemical degradation of isotope labeled (13)C citrate by mass spectrometry. The structure of the acetone modification was determined by nuclear magnetic resonance (NMR) spectroscopy on modified-free glycine and found to correspond to acetone linked to the N-terminus of the amino acid through a methyl carbon. Results from mass spectrometric fragmentation of glycine modified with an acetone adduct derived from (13)C labeled citrate indicated that the three central carbons of citrate are incorporated onto protein amines in the presence of iron and light. While citrate is known to stoichiometrically decompose to acetone and CO(2) through various intermediates in photochemical systems, it has never been shown to be a causative agent in protein carbonylation. Our results point to a previously unknown source for the generation of reactive carbonyl species. This work also highlights the potential deleterious impact of trace metals on recombinant protein therapeutics formulated in citrate buffers.

Abstract
The trifluoromethylphenyl P2 motif from previously reported heteroarylnitrile series has been successfully applied for the design and synthesis of highly potent novel ketoamide-based cathepsin S inhibitors. The key in this process is the change of the torsion angle between the P2 phenyl ring and the attached secondary amide by adding a small Cl, F, or Me group at the 2-position.

Abstract
Three cases of Legionnaires disease caused by Legionella longbeachae Sg 1 associated with potting compost have been reported in Scotland between 2008 and 2009. The exact method of transmission is still not fully understood as Legionnaires disease is thought to be acquired by droplet inhalation. The linked cases associated with compost exposure call for an introduction of compost labelling, as is already in place in other countries where L. longbeachae outbreaks have been reported.

Abstract
Morphing structural features of HTS-derived chemotypes led to the discovery of novel 2-cyano-pyrimidine inhibitors of cathepsin K with good pharmacokinetic profiles, for example, compound 20 showed high catK potency (IC(50)=4nM), >580-fold selectivity over catL and catB, and oral bioavailability in the rat of 52%.
