Abstract
BACKGROUND Patterns in sedentary time (SED) and its impact on quality of life (QoL) in cancer survivors during the COVID-19 pandemic remains unknown. The purpose of this study was to 1) compare total and domain-specific SED before and during the pandemic; and 2) examine its association with QoL in a global sample of cancer survivors. METHODS In an online survey, cancer survivors retrospectively self-reported domain-specific SED (e.g. transportation, television) before and during the pandemic via the Domain-Specific Sitting Time Questionnaire. QoL was assessed via the Functional Assessment of Cancer Therapy (FACT)-General and FACT-Fatigue. Paired t-tests compared daily SED before and during the pandemic. Analysis of covariance compared QoL among: those who remained high (>8 h/day), remained low (<8 h/day), increased (<8 h/day to >8 h/day), or decreased (>8 h/day to <8 h/day) daily SED. RESULTS Among cancer survivors (N = 477, Mage=48.5 ± 15.4), 60.8% reported that their SED remained high, 19.7% remained low, 7.5% increased SED, and 11.9% decreased SED. Computer and television screen time significantly increased (p's<.001), while SED during transportation significantly decreased (p<.001). Sub-group analyses revealed that those who reduced SED who were normal or underweight (p=.042) or were meeting physical activity guidelines (p=.031) had significantly less fatigue than those who increased or remained high in SED, respectively. Those who remained high in SED with <3 comorbidities (p's =.005) had significantly better social well-being than those who increased SED. CONCLUSIONS As we transition to a post-pandemic era, behavioral strategies for cancer survivors should focus on reducing screen time to improve QoL and fatigue.

Abstract
PURPOSE Exercise is beneficial for people living with and beyond cancer (LWBC); however, many people LWBC fail to meet the exercise guidelines. Having an identity related to exercise, a component of one's self-concept, correlates with exercising more frequently in general adult populations. Understanding how exercise identity influences exercise behaviors in people LWBC is warranted due to the many barriers people LWBC face in relation to physical activity. The purpose of this study was to explore the perceived impact of an exercise identity of the exercise behaviors and motivations among people LWBC. METHODS Thirteen participants of mixed diagnoses (Mage = 60.8 ± 10.8 years) in the early survivorship period (i.e., within five years of primary treatment completion or diagnosis) participated in semi-structured interviews to identify influences of exercise identity on exercise behavior. Interviews were transcribed verbatim and analyzed using thematic analysis. RESULTS Findings demonstrated that people LWBC with a strong exercise identity engage in high and varied exercise behaviors. Despite barriers such as changes in motivations and ability to engage in exercise, participants maintained exercise throughout cancer by constant adaptation of their outlook and behaviors related to exercise. These results demonstrate a maintenance of physical activity in relation to a strong exercise identity. IMPLICATIONS FOR CANCER SURVIVORS Results of this study have implications for the design and implementation of exercise behavior change programs for people LWBC as it provides insights into predictors of sustained exercise behavior during and following cancer treatment.

Abstract
BACKGROUND Physical activity (PA) and reductions in sedentary behavior (SED) may mitigate cancer-related cognitive impairment. The purpose of this study was to examine (a) the associations between changes in PA, SED, and cognitive function in cancer survivors before and during the coronavirus disease 2019 (COVID-19) pandemic; and (b) clinical subgroups that moderate this association. METHODS A cross-sectional survey was administered online to adult cancer survivors globally between July and November of 2020. This was a secondary analysis of a cross-sectional survey examining changes in self-reported PA and quality of life in cancer survivors before and during the COVID-19 pandemic. Self-reported Questionnaires assessed moderate-to-vigorous PA (MVPA) using the modified Godin Leisure Time Exercise Questionnaire, cognitive function using the Functional Assessment of Cancer Therapy-Cognitive Function (FACT-Cog) scale, and SED using the Domain-specific Sitting Time questionnaire. Cancer survivors were classified into no change in behavior, desirable change (i.e., increase MVPA to meet PA guidelines or decrease SED by ≥60 min/day), and undesirable change (i.e., decrease MVPA to <150 min/week or increase SED by ≥60 min/day). Analysis of covariance examined differences in FACT-Cog scores across the activity change categories. Planned contrasts compared differences in FACT-Cog scores between cancer survivors with (a) no meaningful change vs. any change, and (b) a desirable change vs. an undesirable change. RESULTS There were no significant differences in FACT-Cog scores across activity-change categories in the full sample of cancer survivors (n = 371; age = 48.6 ± 15.3 years (mean ± SD)). However, cancer survivors who were diagnosed ≥5 years ago (t(160) = -2.15, p = 0.03) or who received treatment ≥5 years ago (t(102) = -2.23, p = 0.03) and who had a desirable change in activity reported better perceived cognitive abilities than those who had an undesirable change. CONCLUSION PA promotion efforts should consider reducing SED in addition to maintaining MVPA in long-term cancer survivors to mitigate cancer-related cognitive impairment during the COVID-19 pandemic.

Abstract
PURPOSE The COVID-19 pandemic has imposed additional barriers to physical activity (PA) in cancer survivors. Adaptations to PA programmes are needed during the pandemic. Therefore, the purpose of this study was to evaluate (1) the PA preferences of cancer survivors prior to and during the pandemic and (2) the available resources to engage in PA during the pandemic. METHODS Using a cross-sectional study design, cancer survivors were recruited globally to participate in a self-administered survey assessing their PA preferences and available PA resources during the pandemic. Descriptive statistics were used to determine trends in PA preferences and resources. A sub-group analysis was conducted for age, gender, education, and PA levels. RESULTS Cancer survivors (N = 493) were mainly women (70.4%) diagnosed with breast cancer (29.0%), with a mean age of 48.7 ± 15.8 years, and 87.1 ± 81.9 months since diagnosis. Since the start of the pandemic, cancer survivors were primarily walking (82.6%), and performing PA alone (62.7%) and at home (46.6%). Sub-group analysis revealed education level, PA levels, and age to be associated with significant differences in PA preferences. The most common equipment available to survivors in their homes were exercise mats (40.6%) and free weights (39.8%). Few survivors were made aware of at-home PA resources (19.1%), and approximately half indicated wanting to receive these resources (49.6%). CONCLUSIONS Understanding cancer survivors' preferences and resources for PA during the pandemic is critical to designing effective home-based interventions. Interventions and recommendations should be tailored based on the level of education and PA participation, as well as age.

Abstract
PURPOSE Exercise and social support are non-pharmacological strategies that improve health and wellbeing in women treated for breast cancer (WTBC). However, strategies to facilitate support and exercise in WTBC are typically resource intensive. The purpose of this study was to examine whether various forms of social support received from a matched peer were associated with increased exercise among WTBC. METHODS A daily diary study was conducted to examine naturally occurring social support as it relates to daily exercise behavior. Forty-six WTBC were matched (23 pairs) and completed pre-screening survey assessing eligibility and baseline levels of exercise. Participants were given Fitbit devices to track physical activity behavior and completed daily surveys across 3 weeks assessing perceptions of exercise-related social support at fixed times at the end of each day. RESULTS Mixed models accounting for day of study, baseline support, and baseline exercise levels revealed that higher levels of daily exercise-related tangible social support were associated with more daily steps (b = 506, SE = 143) and more light physical activity (LPA) minutes (b = 7.01, SE = 3.15). Informational social support was associated with higher moderate to vigorous physical activity (MVPA) minutes (b = 3.18, SE = 1.60). CONCLUSIONS Overall, peer matching programs aimed at increasing exercise-related social support among WTBC might encourage exercise behaviors, especially among women who share exercise-specific information (e.g., benefits, type, activities).

Abstract
The corneal epithelium is one of the first tissue barriers of the eye against the environment. In recent years, many studies provided better knowledge of its healing, its behavior and its essential role in the optical system of the eye. At the crossroads of basic science and clinical medicine, the study of the mechanical stresses applied to the cornea makes it possible to learn the behavior of epithelial cells and better understand ocular surface disease. We describe herein the current knowledge about the adhesion systems of the corneal epithelium and their resistance to mechanical stress. We will also describe the involvement of these mechanisms in corneal healing and their role in epithelial dynamics. Adhesion molecules of the epithelial cells, especially hemidesmosomes, allow the tissue cohesion required to maintain the integrity of the corneal epithelium against the shearing forces of the eyelids as well as external forces. Their regeneration after a corneal injury is mandatory for the restoration of a healthy epithelium. Mechanotransduction plays a significant role in regulating epithelial cell behavior, and the study of the epithelium's response to mechanical forces helps to better understand the evolution of epithelial profiles after refractive surgery. A better understanding of corneal epithelial biomechanics could also help improve future therapies, particularly in the field of tissue engineering.

Abstract
BACKGROUND The purpose of this study was to test Multi-Process Action Control (M-PAC) processes as correlates of physical activity (PA) intention formation and translation (i.e., action control) in individuals diagnosed with cancer. METHODS This study was a cross-sectional survey, completed from July to November of 2020 during the COVID-19 pandemic. PA and M-PAC processes were self-reported using the Godin Leisure-Time Exercise Questionnaire and questionnaires for reflective (instrumental/affective attitudes, perceived opportunity/capability), regulatory (e.g., goal-setting, planning), and reflexive processes (habit, identity). Separate hierarchical multinomial logistic regression models determined correlates of intention formation and action control. RESULTS Participants (n = 347; Mage= 48.2 ± 15.6) were primarily diagnosed with breast cancer (27.4%) and at a localized stage (85.0%). Most participants intended to perform PA (70.9%), yet only 50.4% met guidelines. Affective judgements (p < 0.001) and perceived capability (p < 0.01) were significantly associated with intention formation. Preliminary models indicated employment, affective judgements, perceived capability, and self-regulation to be significant (ps < 0.05) correlates of action control, but in the final model, only surgical treatment (p = 0.02) and PA identity (p < 0.001) were significantly associated with action control. CONCLUSION Reflective processes were associated with PA intention formation, while reflexive processes were associated with PA action control. Behavior change efforts for individuals diagnosed with cancer should extend beyond social-cognitive approaches to include regulatory and reflexive processes of PA behavior (i.e., PA identity).

Abstract
Barriers to exercise-oncology programs remain for those living with and beyond cancer in rural and remote communities, including geographic isolation and access to programs. The EXercise for Cancer to Enhance Living Well (EXCEL) study was designed to support exercise-oncology implementation in rural and remote communities across Canada. The purpose of this analysis was to evaluate the first-year reach, adoption, and implementation of the EXCEL study. Reach outcomes included participant characteristics, study enrolment, and referral type (self vs. healthcare-provider [HCP] referral). Adoption outcomes included the number of clinical contacts, trained qualified exercise professionals (QEPs), and QEPs delivering EXCEL exercise classes. Implementation outcomes included retention, adherence, assessment completion rates, and adverse-event reporting. A total of 290 individuals living with cancer enrolled in EXCEL in year one, with an 81.4% retention to the study intervention. Most participants self-referred to EXCEL (75.8%). EXCEL's HCP network consisted of 163 clinical contacts, and the QEP network included 45 trained QEPs, 22 of whom delivered EXCEL classes. Adherence to the exercise intervention was 78.2%, and only one adverse event (mild) was reported. Fitness assessment and patient-reported outcome completion rates were above 85% pre- and post-intervention. EXCEL has developed HCP and QEP networks supporting exercise referral and online delivery, and the intervention is meeting feasibility markers. These implementation findings will inform the continued gathering of feedback across stakeholders to ensure that best evidence informs best practices.

Abstract
Physical activity (PA) can help manage cancer treatment-related side effects and improve well-being following treatment; however, resuming PA after a period of inactivity due to cancer can be challenging. The purpose of this study was to explore adolescents and young adults (AYAs) experiences transitioning back into PA after a period of inactivity due to cancer treatment. Twelve previously active AYAs (Mage = 30 ± 5.8 years) were purposefully sampled and engaged in a semi-structured interview. The following four themes were generated through a reflexive thematic analysis: PA is described as important and valuable; navigating one's appearance and fitness changes after cancer treatment within the PA context; supportive care is essential to successful PA transitions; and juxtaposed environments: fitness facilities, cities, and green spaces. Developing strategies aimed at gradually transitioning into PA should be a priority to improve AYAs' well-being through survivorship.

Abstract
Background Prostate cancer survivors (PCS) experience long-term side effects beyond treatment such as fatigue, depression and anxiety. Quality and engaging supportive care programs are needed to reduce these chronic and debilitating effects. Independent of physical activity (PA), high volumes of sedentary behavior (SB) are associated with chronic disease-related risk factors and poorer cancer-specific quality of life (QoL). Simultaneously increasing PA and decreasing SB may be an effective health promotion strategy. Given that PCS may face several barriers to engaging in supervised programs, there is a need to develop and assess the efficacy of interventions that employ distance-based approaches for behavior change. The primary aim of this study is to determine the effects of a 12-week intervention (Fitbit + behavioral counselling) vs. Fitbit-only control group in reducing SB among PCS. Secondary outcomes include light-intensity PA, QoL, motivational outcomes, and patient satisfaction. Methods This two-armed, randomized controlled trial will recruit inactive PCS (stage I-IV) across Canada who self-report engaging in >8 hours/day of SB. Participants will be randomized to the intervention (n=60; Fitbit and behavioral support) or active control group (n=60; Fitbit-only). The intervention consists of the use of a Fitbit and a series of six behavioral support sessions (two group, four individual) to aid PCS in gradually replacing SB with light-intensity PA by increasing their daily step counts to 3,000 steps above their baseline values. The Fitbit-only control condition will receive a Fitbit and public health PA resources. The primary outcome is change in SB measured objectively using activPAL inclinometers. All secondary outcomes will be measured via self-report, except for PA which will be measuring using Fitbits. Data will be collected at baseline, post-intervention, and at 6-month post-intervention. Discussion Reducing SB and increasing light-intensity PA plays an important, yet often undervalued role in the health and well-being of PCS. This study will create a unique distance-based platform that can be used by clinical and community-based organizations as a low-cost, supportive care tool to improve health outcomes for PCS.

Abstract
Physical activity (PA) is important for managing the side effects and long-term outcomes of cancer treatment, yet many adolescents and young adults diagnosed with cancer (AYAs) are not meeting PA guidelines. Body image and social support are two factors that can influence PA behavior and require further attention in this population. The purpose of this study was to examine the associations between body image, social support, and PA among AYAs. An online cross-sectional survey administered through the Research Electronic Data Capture platform was used to assess self-reported body image (body-related self-conscious emotions of appearance and fitness shame, guilt, authentic pride, and hubristic pride), social support (general and cancer-specific), and PA (mild, moderate-to-vigorous, and resistance exercise) in AYAs (N = 119; M age = 34.5 ± 5.5 years). Based on findings from path analyses, body image and social support were directly associated with PA (R 2 = 0.09-0.33). Social support was also directly associated with body image. However, there were no indirect effects. These findings provide preliminary support for the influential role of appearance and fitness body-related emotions and cancer-specific social support on PA. The results have important implications for the development of targeted strategies aimed at improving body image (e.g., cognitive dissonance and compassion-focused interventions) and social support (e.g., facilitating the provision of cancer-specific support), with the overall goal of increasing AYAs' PA.

Abstract
BACKGROUND Peer-based exercise interventions that cultivate new opportunities for support with a fellow cancer survivor may result in increased exercise volume. It is not clear whether adding qualified exercise professional (QEP) support to peer-based interventions improves health outcomes. Therefore, the purpose of this study is to determine whether breast cancer survivor (BCS) dyads who receive 10 weekly sessions of virtually delivered QEP support have improved outcomes compared to BCS dyads who do not receive QEP support. METHODS Participants Adult BCS with medical clearance for exercise, who have an internet-connected device, and currently engage in < 150 min of moderate-intensity exercise per week. Intervention BCS will be matched using evidence-based criteria. The intervention group will receive dyadic exercise information sessions and a program tailored by a QEP for 10 weeks (intervention period) and have access to the QEP for an additional 4 weeks (tapering period). The control will not receive any QEP support. Outcomes The primary outcome is post-intervention self-reported exercise volume. Secondary outcomes include device-assessed exercise volume (i.e., Fitbit), social support, and health-related quality of life. Randomization 108 participants, matched in dyads, will be randomized 1:1 to the MatchQEP or Match groups using a web-based scheme. Statistical analysis Outcomes will be measured at baseline, post-intervention, post-tapering, and at 12 weeks post-intervention follow-up. DISCUSSION The findings from this RCT will determine if matched BCS dyads who receive 10 weeks of virtually delivered QEP support have higher levels of self-report and device-measured exercise, social support, and health related quality of life compared to matched dyads without QEP-delivered exercise guidance. To our knowledge this will be the first study to assess the combined effect of peer- and QEP support on exercise volume. Project findings will inform and optimize intervention methods aimed to increase exercise among BCS through accessible exercise supports. TRIAL REGISTRATION The study is registered on ClinicalTrials.gov (study identifier: NCT04771975, protocol Version Number: 2, date: July 22, 2021).

Abstract
Abstract
Objectives
To establish the preferences and perceived barriers related to physical activity and diet programming of breast cancer survivors (BCS) to inform the development of Information and Communication Technology (ICT)-based lifestyle interventions.
Methods
This was a cross-sectional study of 197 BSC aged 18 years or older and diagnosed with ductal carcinoma in situ (DCIS) or Stage I-IV breast cancer. The BCS were recruited during routine oncology appointments at a Midwestern cancer center. A survey was conducted to query survivors’ level of interest in, preferences for, and perceived barriers to participating in an exercise and dietary intervention program, with a specific emphasis on ICT-based programming.
Results
Overall, 85% of BCS reported they would consider participating in exercise and diet intervention research. Approximately 45% of participants reported that they had received diet and/or exercise information as part of their cancer care. However, only 15% of the participants received such information from healthcare professionals with the appropriate expertise (e.g., Dietitian, Exercise Specialist). Over two-thirds of the participants reported frequent use of mobile devices and the internet, and 80% indicated comfort using these devices (e.g., tablet, smart phone). The top three preferred formats for an ICT-based diet and exercise intervention program were “website”, “mobile apps” and “e-mails”. Older participants (>60 years) were more likely to report a preference for e-mails while younger participants (<60 years) were more likely to report a preference for websites or mobile apps. The most common perceived barriers to participation in a lifestyle intervention included fatigue, family responsibility and work.
Conclusions
Most BCS in this study were interested in exercise and diet interventions and would be comfortable with an ICT-based format with a preference for delivery via websites, mobile apps or e-mails. Future ICT-based lifestyle interventions should be designed with consideration of BCS’ age, barriers, facilitators and other characteristics.

Abstract
Intracorneal ring segments (ICRS), used in the management of keratoconus since the 2000s, have enjoyed significant technological development. Various types of ICRS exist, whose arc length, thickness, and diameter can be chosen according to the desired effect on the spherical equivalent, keratometry and asphericity. Individualized implantation strategies, based on each patient's topographic and tomographic pattern, are constantly evolving. The surgical procedure is standardized, and complications remain very rare. Combined procedures (corneal collagen cross-linking and refractive photokeratectomy±topo-guided, phakic and pseudophakic intraocular lenses) are increasingly used and require a good knowledge of the effect of ICRS alone on the keratoconic cornea. The objective of this review is to summarize clinical practices used in the visual rehabilitation of keratoconic patients using the ICRS+- combined procedures.

Abstract
OBJECTIVE Cancer and treatment can produce temporary or permanent body changes, which may affect the body image (BI) of adolescents and young adults diagnosed with cancer (AYAs). This evidence has not been comprehensively summarized. A scoping review was conducted to explore the available evidence on BI among AYAs and identify the definitions, theories, models, frameworks, measures, and methods used to assess BI. METHODS Databases MEDLINE, EMBASE, PsycINFO (via Ovid) and CINAHL and Gender Studies (via EBSCO) were searched to identify published studies from 1 January 2000 to 25 November 2019. Inclusion criteria were: qualitative, quantitative, or mixed methodology; at least one BI-related measure or theme; published in English; and majority of the sample between 13 and 39 years at diagnosis and a mean age at diagnosis between 13 and 39 years. Two authors screened the titles, abstracts, and full-text articles and data were extracted and summarized. RESULTS The search yielded 11,347 articles and 82 met inclusion criteria. Articles included 45 quantitative, 33 qualitative, and four mixed-methods studies. The majority of studies used cross-sectional designs, while BI definitions, theories, models, frameworks, and measures were varied. Studies explored descriptive, psychological, physical, coping, and social factors, with BI being described most often as an outcome rather than a predictor. CONCLUSIONS Theory-based research that employs a holistic BI definition and uses longitudinal or intervention study designs or a qualitative methodology is needed to better understand the BI experience of AYAs and inform the development of strategies and programs to reduce BI concerns and increase positive body experiences.

Abstract
Purpose This study aimed to evaluate the ability of a freely accessible internet algorithm to correctly identify the need for emergency ophthalmologic consultation for correct diagnosis and management. Method This retrospective observational cohort study was based on the first 100 patients who requested recommendations on the necessity of breaking the lockdown for emergency ophthalmology consultation during the period from March to May 2020. Results Ninety-one patients completed questionnaires. Forty-nine were directed to emergency consultation and 42 to differed scheduled visits or telemedicine visits. One patient sent for emergency consultation had an overestimated severity and could have been seen later, while two patients initially recommended for a scheduled visit were considered appropriate for emergency consultation. However, these patients’ management did not suffer as a consequence of the delay. The sensitivity of the algorithm, defined as the number of emergency consultations suggested by the algorithm divided by the total number of emergency consultations deemed appropriate by the practitioner's final evaluation, was 96.0%. The specificity of the algorithm, defined as the number of patients recommended for delayed consultation by the algorithm divided by the number of patients deemed clinically appropriate for this approach, was 97.5%. The positive predictive value, defined as the number of appropriate emergency consultations divided by the total number of emergency consultations suggested by the algorithm, was 97.9%. Finally, the negative predictive value, defined as the number of appropriately deferred patients divided by the number of deferred patients recommended by the algorithm, was 95.2%. Conclusion This study demonstrates the reliability of an algorithm based on patients’ past medical history and symptoms to classify patients and direct them to either emergency consultation or to a more appropriate deferred, scheduled appointment. This algorithm might allow reduction of walk-in visits by half and thus help control patient flow into ophthalmologic emergency departments.

Abstract
OBJECTIVES To summarize the current available evidence on the use of behavior change theories to explain and change physical activity behavior in urological cancer survivors. DATA SOURCES Five electronic databases including Medline, Web of Science, Embase, Cochrane, and Psych INFO and reference lists of key studies were searched between database inception and November 2020. Peer-reviewed articles on the use of behavior change theories to understand or change physical activity in urological cancer survivors were included. CONCLUSION The theory of planned behavior and the social cognitive theory were the most used theories to explain and change physical activity behavior in urological cancers, respectively. However, the use of behavior change theories in physical activity interventions for urological cancers is still low across all urological tumor groups. Planning frameworks such as the intervention mapping approach should be used to enhance the systematic use of behavior change theories during every phase of intervention development. In addition, more research is needed to identity which behavior change techniques are most effective to change physical activity behavior in urological cancer survivors. IMPLICATIONS FOR NURSING PRACTICE Nurses play a key role in the urological cancer patients' clinical pathway and should be able to motivate patients to engage in sufficient physical activity levels. Therefore, it is important that nurses understand the underlying reasons why patients (do not) engage in physical activity and which behavior change techniques are most effective in changing a patients' behavior.

Abstract
Purpose Exercise and physical activity (hereafter, collectively referred to as PA) preferences and benefits are becoming increasingly well characterised in cancer survivors, yet evidence from adolescent and young adult cancer survivors (AYAs) is scant. We describe the overall PA behaviour and support preferences of AYAs and explore subgroup differences to inform AYA-specific research and support. Methods AYAs diagnosed with cancer between the ages of 18–39 years, irrespective of current age, were approached in clinic at a large cancer centre for this cross-sectional survey that assessed self-reported demographics, medical history, PA behaviour and PA support preferences. Results A total of 318 AYAs completed the survey. Approximately 40% of AYAs were not meeting PA guidelines, and only 5% reported engagement with cancer PA support services. Most AYAs wanted PA support (78%), to increase PA levels (70%), and were interested in engaging in PA interventions that were individually supervised (82%), home-based (79%), performed ≥ 3 days/week (75%) and for ≥ 30 minutes/session (78%), offered following treatment (63%), restricted by age (63%), and involved strength (83%), walking (78%), and flexibility (75%) exercise. PA preferences most often differed according to sex, treatment status, current PA behaviour and PA support setting. Conclusion AYAs have a great capacity and interest in specific types of PA support. Poor engagement with existing PA support services highlights the need for further AYA-specific research. Better understanding of AYAs' unique PA behaviour and support preferences can inform the development of urgently needed research and support services for this understudied and rapidly growing population.

Abstract
PURPOSE To determine whether manifest refractive astigmatism (RA) or anterior corneal astigmatism (CA) is the best value for excimer laser programming in cases of ocular residual astigmatism (ORA). PATIENTS AND METHODS Patients who had undergone LASIK surgery with a disagreement between manifest refractive and corneal cylinder (ocular residual astigmatism ORA)>0.75 D were included retrospectively in this study. We calculated target induced astigmatism vector (TIA), surgically induced astigmatism vector (SIA), difference vector between the astigmatism correction programmed in the excimer laser and refractive astigmatism (DVRA), difference vector between the astigmatism correction programmed in the excimer laser and corneal astigmatism (DVCA) and difference vector between TIA and SIA (DV), by the Alpins method. Vectorial differences between DV and DVRA, and between DV and DVCA, were then calculated to determine whether RA or CA was closest to the ideal cylinder for laser programming. RESULTS Of a total of 104 eyes undergoing LASIK, 22 eyes of 12 patients (21.1%) had an ORA>0.75 D and were included. Mean ORA was 0.9±0.2 D and mean postoperative subjective cylinder was 0.45 D. The DV-DVRA difference vector was 0.57±0.2 D, and the DV-DVCA difference vector was 0.86±0.4 D (P=0.02). RA was closer than CA to the ideal astigmatism correction. CONCLUSION In cases of discrepancy between manifest astigmatism and corneal astigmatism, correction of manifest refractive astigmatism seems to give a better refractive result.

Abstract
Breast cancer survivors (BCS) engage in more sedentary behavior (SED) than those without cancer. However, the context in which SED is accrued is unknown. The purpose of this study is to examine differences in total and domain-specific SED of BCS and healthy controls. 20 BCS and 20 age-matched, healthy controls wore ActiGraph GT3X + accelerometers to measure SED and activity. Participants self-reported SED for transportation, occupational, screen time and leisure purposes. Multiple linear regressions were used to estimate differences in SED between BCS and controls. BCS spent significantly more time watching TV (152.4 vs. 60.3; p < 0.01) and less time in total SED (490.8 vs. 587.4; p = 0.046) and other leisure activities (57.6 vs. 106.9; p < 0.01) than healthy controls. BCS engage in more TV watching and less time in other leisure activities than controls, thus interventions should focus on reducing TV time. Understanding facilitators of TV viewing is needed to determine specific intervention targets.

Abstract
OBJECTIVE This three-armed randomized controlled feasibility trial tested the acceptability and acute effects of aerobic exercise and technology-guided mindfulness training (relative to standalone interventions) on cancer-related fatigue among breast cancer survivors (BCS). METHODS BCS recruited from Central Illinois completed pre- and post-testing using established measures and were randomized to one of three groups (combined aerobic exercise with guided-mindfulness relaxation, aerobic exercise only, and relaxation only), conducted in three 90 min sessions over the course of 7 days in a fitness room and research office on a university campus. RESULTS We enrolled 40 BCS (Mage = 57.33 ± 8.75), MBMI = 27.38 ± 5.27, Mfatigue = 4.56 ± 1.81 as measured by the Piper Fatigue Scale. More favorable post-intervention evaluations were reported by the combined group, compared to aerobic exercise or relaxation only (p < 0.05). Reductions in fatigue favoring the combined group (p = 0.05) showed a modest effect size (Cohen's d = 0.91) compared to aerobic exercise only. CONCLUSIONS These findings provide preliminary evidence for the feasibility of combining evidence-based techniques to address fatigue among BCS. The combined approach, incorporating mobile health technology, presents an efficacious and well-received design. If replicated in longer trials, the approach could provide a promising opportunity to deliver broad-reaching interventions for improved outcomes in BCS. Preregistered-ClinicalTrials NCT03702712.

Abstract
OBJECTIVE To examine the differential effects of acute exercise duration on domains of executive function and processing speed in patients with breast cancer. METHODS Participants (N = 48, M age = 56.02 ± 10.99) completed two sessions in counterbalanced order: moderate-intensity treadmill walking and sitting. Participants were also randomized to one of three duration conditions: 10 (n = 15), 20 (n = 16), or 30 (n = 17) min, reflecting the length of time spent walking and sitting. Immediately before and after each session, women completed a battery of cognitive tasks (e.g., inhibition, cognitive flexibility, spatial working memory, and processing speed). RESULTS Within- and between-subjects repeated-measures analyses of variance revealed time by condition interactions on both processing speed (p = 0.02) and spatial working memory (ps < 0.07), such that women demonstrated improved cognitive functioning regardless of the time spent walking. There were also several moderately sized three-way (e.g., time by condition by duration) interactions driven by declines in cognitive functioning after sitting on cognitive flexibility in the 10 (d = -0.96) and 30-min (d = -0.52) groups and inhibition in the 20-min group (d = 0.75). On the processing speed task, women performed significantly faster after walking compared with after sitting in the 20-min group (d = -0.24). CONCLUSIONS For select cognitive domains, walking anywhere from 10 to 30 min is associated with significant benefits. Our findings suggest the need for further research into the mechanisms and dose-response relationships between acute exercise and cognition as well as how such acute bouts may be accumulated for larger, lasting cognitive benefits after breast cancer.

Abstract
BACKGROUND Falls are prevalent among cancer survivors, and neuropathy, a side effect from chemotherapy treatment, is thought to contribute to falls. While falls commonly occur during walking, there is limited information about gait function in cancer survivors with neuropathy. RESEARCH QUESTION What is the difference between gait speed and gait variability in cancer survivors with and without self-reported neuropathy and healthy controls? METHODS Seventeen cancer survivors and 12 healthy individuals [age: 53.5 (11.8), gender: 10 females] participated in a single testing session. Cancer survivors were grouped into neuropathy [n = 9; age: 61.9 (6.1); gender: 8 females] and no neuropathy [n = 8; age: 50.75 (14.1); gender: 7 females] based on the self-reported FACT/GOG Neurotoxicity subscale questionnaire. All participants completed two walking trials at their comfortable pace across a 6 m pressure sensitive walkway. A one-way ANOVA with Tukey's post-hoc analysis and effect sizes were used to detect differences in gait speed, step length variability, and step width variability between groups. RESULTS Although there were no group differences in gait speed, a significant main effect was found for step length variability (p = 0.03, η2 = 0.24) between groups. Step length variability was significantly less in cancer survivors with neuropathy than healthy controls (p = 0.05, d = 1.30). There was a significant main effect for step width variability between groups (p = 0.05, η2 = 0.20). Cancer survivors with neuropathy had significantly greater step width variability than healthy controls (p = 0.04, d = 1.04). SIGNIFICANCE Cancer survivors with neuropathy display greater step width variability and less step length variability than healthy controls. Gait variability may be a more sensitive marker than gait speed to track mobility in cancer survivors with neuropathy symptoms. Assessing and treating gait function in cancer survivors with neuropathy symptoms may improve everyday ambulation.

Abstract
BACKGROUND Physical activity is effective for the prevention and treatment of chronic disease, yet insufficient evidence is available to make comparisons regarding adherence to aerobic physical activity interventions among chronic disease populations, or across different settings. The purpose of this review is to investigate and provide a quantitative summary of adherence rates to the aerobic physical activity guidelines among people with chronic conditions, as physical activity is an effective form of treatment and prevention of chronic disease. METHODS Randomized controlled (RCTs) trials where aerobic physical activity was the primary intervention were selected from PsychInfo, PubMed, CINAHL (Cumulative Index to Nursing and Allied Health Literature), Clinical Key, and SCOPUS from 2000 to 2018. Studies were included if the program prescription aligned with the 2008 aerobic physical activity guidelines, were at least 12 weeks in length, and included adult participants living with one of three chronic diseases. The data was extracted by hand and the PRISMA (preferred reporting items for systematic review and meta-analysis) guidelines were used to evaluate risk-of-bias and quality of evidence. Data were pooled using random-effect models. The primary outcome measure was program adherence and the secondary outcome measures were dropout and setting (e.g. home vs. clinic-based). Pooled effect sizes and 95% CiIs (confidence intervals) were calculated using random-effect models. RESULTS The literature search identified 1616 potentially eligible studies, of which 30 studies (published between 2000 and 2018, including 3,721 participants) met the inclusion criteria. Three clinical populations were targeted: cancer (n = 14), cardiovascular disease (n = 7), and diabetes (n = 9). Although not statistically significant, adherence rates varied across samples (65, 90, and 80%, respectively) whereas dropout rates were relatively low and consistent across samples (5, 4, and 3%). The average adherence rate, regardless of condition, is 77% (95% CI = 0.68, 0.84) of their prescribed physical activity treatment. The pooled adherence rates for clinic-based and home-based programs did not differ (74% [95% CI, 0.65, 0.82] and 80% [95% CI, 0.65, 0.91], respectively). CONCLUSIONS The current evidence suggests that people with chronic conditions are capable of sustaining aerobic physical activity for 3+ months, as a form of treatment. Moreover, home-based programs may be just as feasible as supervised, clinic-based physical activity programs.

Abstract
OBJECTIVE To examine the association between accelerometer activity counts and energy expenditure during walking in breast cancer survivors (BCS) compared with age-matched healthy controls, and differences in moderate-to-vigorous physical activity (MVPA) cut-points. METHODS Using a case-control design, 19 BCS and 19 age-matched women completed 6 min of resting energy expenditure and 6-min periods of treadmill walking in Midwestern United States. Accelerometers and an open-circuit spirometry system were used to measure activity counts and energy expenditure (VO2 ). A mixed-factor analysis of variance was conducted on activity counts and VO2 . Independent samples t tests compared the magnitude of associations between groups. RESULTS There were group by speed interactions on energy expenditure (p < 0.001) and counts (p < 0.001). The linear association did not differ between BCS and controls for the R2 (p = 0.62) nor the slope (p = 0.43), but there was a difference in the intercept (p = 0.01). This resulted in different MVPA cut-points between groups: 1,439 ± 761 counts·min-1 in BCS and 1,937 ± 639 counts·min-1 in controls. CONCLUSION The findings support the use of different cut-points to quantify time spent in MVPA for BCS. Application of these cut-points is warranted to accurately assess physical activity (PA) patterns for better prescription and health outcomes in PA programmes for BCS.

Abstract
PURPOSE Guidelines for cancer survivors recommend both aerobic physical activity (PA) and strength training (ST). Few kidney cancer survivors (KCS) are meeting single-activity or combined guidelines; therefore, examining factors influencing PA participation is warranted. The purpose of this study is to examine demographic, medical, social-cognitive, and environmental correlates of meeting independent (i.e., aerobic-only, strength training (ST)-only) and combined guidelines (i.e., aerobic and ST) in KCS. METHODS KCS (N = 651) completed self-reported measures of PA and demographic, medical, social-cognitive, and perceived environmental factors. Built environment was assessed using the geographic information systems (GIS). Multinomial logistic regressions were conducted to determine the correlates of meeting the combined versus independent guidelines. RESULTS Compared with meeting neither guideline, meeting aerobic-only guidelines was associated with higher intentions (p < .01) and planning (p < .01); meeting ST-only guidelines was associated with higher intentions (p = .02) and planning (p < .01), lower perceived behavioral control (PBC) (p = .03), healthy weight (p = .01), and older age (p < .01); and meeting the combined guidelines were associated with higher intentions (p < .01), planning (p = .02), higher instrumental attitudes (p < .01), higher education (p = .04), better health (p < .01), and localized cancer (p = .05). Additionally, compared with neither guideline, meeting aerobic-only (p < .01) and combined (p < .01) guidelines was significantly associated with access to workout attire. Compared with neither guideline, meeting aerobic-only guidelines was associated with proximity to retail (p = .02). CONCLUSION PA participation correlates may vary based on the modality of interest. Interventions may differ depending on the modality promoted and whether KCS are already meeting single-modality guidelines.

Abstract
Objective To systematically review and quantitatively synthesize gait and balance impairments in breast cancer survivors compared with age-matched controls or normative values for adults who never had breast cancer. Data Sources PubMed, Cumulative Index of Nursing and Allied Health, and Web of Science was searched using terms associated with breast cancer, mobility, and adult until November 2018. Study Selection Studies were included if they were randomized control trials, cross-sectional, prospective, pre-post, or case-control by design, included adult breast cancer survivors, reported gait and/or balance metrics as primary or secondary outcomes, were peer-reviewed publications, and were written in English. The search yielded 2117 results with 29 studies meeting the inclusion criteria. Data Extraction Two reviewers assessed study quality by the National Institutes of Health Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies to determine the strength of evidence for each study that met the inclusion criteria. Basic descriptors of each study, study protocol, and balance and gait measures were extracted. Meta-analysis was performed for the single leg stance, functional reach, center of pressure velocity, gait speed, and timed up and go. Data Synthesis For quality assessment, 3 studies were rated good, 16 fair, and 10 poor. The meta-analysis indicated that there were no significant differences in single leg stance between breast cancer survivors and those who never had breast cancer (P=.33). Pooled values of the functional reach task (22.16cm; 95% CI, 8.98-35.33) and center of pressure velocity (1.2cm/s; 95% CI, 0.87-1.55) suggest balance impairment in breast cancer survivors when compared with normative values. Breast cancer survivors also performed worse than those who never had breast cancer in challenging balance conditions that reduced sensory information or altered base of support. Pooled gait speed at a usual speed (0.91m/s; 95% CI, 0.2-1.6), fast speed across a short distance (1.2m/s; 95% CI, 0.31-2.1), and fast gait speed across a long distance (1.65m/s; 95% CI, 1.64-1.66) suggest gait impairments when compared with normative values. Conclusions Breast cancer survivors may demonstrate gait and balance impairments compared with normative values. Clinicians should consider assessing changes in balance and gait in breast cancer survivors to improve functional independence and prevent fall-related injuries.

Abstract
Refractive surgery is a field in constant evolution. In recent years, a new procedure has appeared under the name SMILE (Small Incision Lenticule Extraction). This technique, carried out solely with a femtosecond laser, should make it possible to better preserve corneal innervation and biomechanics. After a detailed review of the technique itself, we then focus on the scientific evidence for the safety and efficacy of SMILE and its current indications. Advantages of SMILE will be discussed in comparison to disadvantages of the conventional techniques, particularly concerning dry eye and the risk of corneal ectasia with LASIK. Lastly, the current limitations of SMILE (indications, retreatment) are discussed, and future applications are considered regarding improvements in the technique.

Abstract
OBJECTIVES Few exercise oncology trials have compared aerobic with strength exercise or compared combined exercise (ie, aerobic and strength training) with aerobic only or strength only. It is unknown what single or combined exercise modality is optimal for quality of life (QoL) in cancer survivors. The purpose of this study is to estimate the prevalence of meeting the combined and independent aerobic and strength exercise guidelines in kidney cancer survivors (KCS) and determine any associations with QoL. METHODS One thousand nine hundred eighty-five KCS were identified through a provincial registry in Canada and mailed a survey including exercise and QoL scales. RESULTS Completed surveys were received from 703 KCS. Only 10.1% of KCS reported meeting the combined exercise guidelines. Analyses of covariance indicated that, for most QoL outcomes (eg, Functional Assessment of Cancer Therapy-General and Functional Assessment of Cancer Therapy-Fatigue), meeting the combined exercise guideline was superior to meeting either single modality guideline that, in turn, were superior to meeting neither guideline. For the primary outcome of the Trial Outcome Index-Fatigue, meeting the combined exercise guideline was superior to meeting (a) neither guideline (P < 0.001), (b) the strength-only guideline (P = 0.021), and (c) the aerobic-only guideline (P = 0.051). In turn, the aerobic and strength exercise only guidelines were superior to meeting neither guideline (P < 0.001 for aerobic; P = 0.045 for strength) but were not different from each other (P = 0.50). CONCLUSIONS Meeting the combined exercise guideline has favorable associations with QoL in KCS, however, very few KCS are meeting the combined guideline.

Abstract
Objective In this study, we examine the effect of providing an incentive for engagement in self-regulatory behaviors (ie, action planning), in inactive, office-based university employees participating in an 11-week, Web-based walking intervention. Methods Participants were randomly assigned to either control (intervention only) or incentive (intervention plus incentive; CAD $5.00 e-gift card delivered weekly for completing action plans over 4 weeks) conditions. Cohen's d was used to estimate the effect of the incentive on action planning and a RM-ANOVA examined differences in average steps/day, between the 2 conditions, before, during, and after the 4-week incentive period. Results Sixty-nine participants were included in the analysis (incentive: N = 34; control: N = 35; 88% female; Mage = 40.46±10.6 years). A large effect size (d = 1.01) in action plan completion was observed, favoring the incentive condition, with the effect of condition remaining high after incentives were withdrawn (d = 1.0). Greater steps/day favored the incentive condition during the post-incentive period (small effect size; d = 0.28). Conclusions Incentives were effective in encouraging engagement in a self-regulatory strategy (action planning). Future research should examine the optimal incentive structure and timing for engagement.

Abstract
Background Given the high levels of sedentary time and treatment-related side effects in prostate cancer survivors (PCS), interventions targeting sedentary behavior (SED) may be more sustainable compared to physical activity (PA). Purpose To examine the feasibility of a web-based intervention (RiseTx) for reducing SED and increasing moderate-to-vigorous physical activity (MVPA) among PCS undergoing ADT. Secondary outcomes include changes in SED, MVPA, light intensity PA, and quality of life. Methods Forty-six PCS were recruited from two cancer centres in Toronto, Ontario, Canada between July 2015–October 2016. PCS were given an activity tracker (Jawbone), access to the RiseTx website program, and provided with a goal of increasing walking by 3000 daily steps above baseline levels over a 12-week period. A range of support tools were progressively released to reduce SED time (e.g., self-monitoring of steps) during the five-phase program. Objective measures of SED, MVPA, and daily steps were compared across the 12-week intervention using linear mixed models. Results Of the 46 PCS enrolled in the study, 42 completed the SED intervention, representing a 9% attrition rate. Measurement completion rates were 97 and 65% at immediately post-intervention and 12-week follow-up for all measures, respectively. Overall adherence was 64% for total number of logins (i.e., > 3 visits each week). Sample mean age was 73.2 ± 7.3 years, mean BMI was 28.0 ± 3.0 kg/m2, mean number of months since diagnosis was 93.6 ± 71.2, and 72% had ADT administered continuously. Significant reductions of 455.4 weekly minutes of SED time were observed at post-intervention (p = .005). Significant increases of + 44.1 for weekly minutes of MVPA was observed at immediately post-intervention (p = .010). There were significant increases in step counts of + 1535 steps from baseline to post-intervention (p < .001). Conclusions RiseTx was successful in reducing SED and increasing MVPA in PCS. PCS were satisfied with the intervention and its components. Additional strategies may be needed though for maintenance of behavior change. The next step for RiseTx is to replicate these findings in a larger, randomized controlled trial that will have the potential for reducing sedentary time among PCS. Trial registration NCT03321149 (ClinicalTrials.gov Identifier).

Abstract
BACKGROUND Physical activity (PA) participation and adherence among cancer survivors is low, despite research indicating numerous physical, psychological and emotional health benefits of exercise. Tailoring exercise programs specific to the PA preferences in cancer survivors has merit for increasing PA participation and adherence to accrue these benefits. This systematic review identifies and differentiates PA programming and counseling preferences of adult cancer survivors across various cancer survivor groups. METHODS PubMed, SPORTDiscus, Scopus, PsycINFO, EMBASE, Web of Science and CINAHL were electronically searched (inception to Oct 2017) and articles were identified using PRISMA guidelines. Two reviewers independently assessed identified articles to determine eligibility and then individually performed a quality assessment on all final studies. Extracted and analyzed data included participant characteristics, interest in exercise counseling and programming, as well as specific exercise and counseling preferences (e.g. location, timing, intensity). RESULTS Forty-one articles were included in this systematic review. Most studies assessed mixed cancer survivor groups or breast cancer survivors. Most cancer survivors felt able and interested in participating in a PA program, though starting a PA program after or before treatment was preferred. Walking was the strongest PA modality preference, and most cancer survivors preferred moderate intensity PA. Cancer survivors also indicated preferences for home-based PA that could take place in the morning. Slight preferences were found towards physical activity counseling delivered by a fitness expert from a cancer center. Both quantitative and qualitative studies were found to be of moderate to high quality based on the Appraisal Tool for Cross-Sectional Studies (AXIS) and the Consolidated Criteria for Reporting Qualitative Research (COREQ), respectively. CONCLUSION Cancer survivors have an interest in participating in PA programs with walking as the primary modality. Additionally, morning-based PA programs that can be tapered to home-based programs are desirable. However, there was wide variation in other PA preference variables, suggesting multiple program options would be beneficial. Many cancer survivors felt interested and able to participate in PA, and therefore designing PA programs that are tailored to cancer survivors is integral for optimizing recruitment and adherence, as well as enhancing health outcomes in cancer survivors.

Abstract
Food recalls due to undeclared allergens or contamination are costly to the food manufacturing industry worldwide. As the industry strives for better manufacturing efficiencies over a diverse range of food products, there is a need for the development of new analytical techniques to improve monitoring of the presence of unintended food allergens during the food manufacturing process. In particular, the monitoring of wash samples from cleaning in place systems (CIP), used in the cleaning of food processing equipment, would allow for the effective removal of allergen containing ingredients in between food batches. Casein proteins constitute the biggest group of proteins in milk and hence are the most common milk protein allergen in food ingredients. As such, these proteins could present an ideal analyte for cleaning validation. In this work, molecularly imprinted polymer nanoparticles (nanoMIPs) with high affinity toward bovine α-casein were synthesized using a solid-phase imprinting method. The nanoMIPs were then characterized and incorporated into label free surface plasmon resonance (SPR) based sensor. The nanoMIPs demonstrated good binding affinity and selectivity toward α-casein (KD ∼ 10 × 10-9 M). This simple affinity sensor demonstrated the quantitative detection of α-casein achieving a detection limit of 127 ± 97.6 ng mL-1 (0.127 ppm) which is far superior to existing commercially available ELISA kits. Recoveries from spiked CIP wastewater samples were within the acceptable range (87-120%). The reported sensor could allow food manufacturers to adequately monitor and manage food allergen risk in food processing environments while ensuring that the food produced is safe for the consumer.

Abstract
OBJECTIVE Depression symptoms are prevalent among breast cancer survivors (BCS). Reducing sedentary behavior (SED) may be a non-pharmaceutical strategy for alleviating depression symptoms. However, little is known about SED among BCS. The present study aimed to: (i) describe SED behaviors among BCS and identify unique SED groups based on different SED dimensions; (ii) identify personal and cancer-specific factors that discriminate SED clusters; and (iii) examine the association between SED clusters and depression symptoms. METHODS Baseline self-report demographic and medical information was collected from 187 BCS. SED and physical activity were assessed over seven days using an accelerometer. Self-reported depression symptoms were reported three months later. Multiple dimensions of SED were identified and examined in cluster analysis. The clusters were examined for differences using multivariate analysis of variance and chi-square analyses. The difference in depression symptoms among SED groups was assessed using an analysis of covariance. RESULTS High and low SED groups were identified. Survivors in the high SED cluster were significantly older, heavier, less physically active, reported less education, and were more likely to have undergone lymph/axial node dissection. Women in the high SED cluster reported significantly higher depression symptoms prospectively (M = 9.50, SD = 6.07) compared to women in the low SED group (M = 6.89, SD = 5.18), F(8,179) = 4.97, p = 0.03, R2 = 0.34. CONCLUSIONS The importance of understanding multiple dimensions of SED among BCS was highlighted. Reducing SED during the early survivorship period may alleviate depression symptoms.

Abstract
Abstract
Introduction:
Despite recommendations by breast cancer guidelines, that immediate breast reconstruction (IBR) should be offered to all breast cancer patients considered for mastectomy national IBR rates have been reported as low as 12% in Australia. We report our oncoplastic breast cancer unit experience on acceptance of IBR, where it is routinely offered for all the medical fit breast cancer patients.
Methods:
We retrospectively reviewed, prospectively collected data on IBR by 3 oncoplastic breast cancer surgeons from 1st of September 2014 to 31st of March 2016.Patients were considered to be unfit for IBR if they were American Society of Anasthesiologist (ASA) Score 4 or 5, have unstable psychiatric illness, inflammatory breast cancer or high metastatic cancer burden. All the patients who were fit for IBR were offered both prosthetic and autologous IBR options.
Results:
137 patients underwent mastectomy operation, of whom 27 were considered unfit for IBR. Of the remaining 110 patients, 84 (76%) accepted IBR. Of the patients who had IBR 64 (76%) had single stage prosthetic, 15 (18%) two stage prosthetic and 5 (6%) autologous reconstructions. Those who accepted IBR were younger compared to those who didn't have IBR (median age: 47 yrs vs. 67 yrs, p<0.001), and were more likely to be in current relationship (78.57% vs. 61.54%, p=0.06). All the three surgeons had high IBR acceptance rates (70.45%, 71.43%, 84.44%) and patient insurance status did not influence IBR acceptance rate (public 57% vs. private 65%, p=0.47). The majority of patients (25 of 26) who did not accept IBR stated that breast reconstruction was not important for their body image.
Conclusion:
Our recent data shows, in Australia, when routinely offered to breast cancer patients who are fit for reconstructive surgery by oncoplastic breast cancer surgeons, IBR is highly accepted. Younger patients and those who are in current relationship, were more likely to accept IBR, whereas, individual perception of insignificance of breast reconstruction for the body image was the main determinant of not accepting IBR.

Abstract
AIMS People with Type 1 diabetes have smaller pancreases than healthy individuals. Several diseases causing pancreatic atrophy are associated with pancreatic steatosis, but pancreatic fat in Type 1 diabetes has not been measured. This cross-sectional study aimed to compare pancreas size and fat fraction in children with Type 1 diabetes and controls. METHODS The volume and fat fraction of the pancreases of 22 children with Type 1 diabetes and 29 controls were determined using magnetic resonance imaging. RESULTS Pancreas volume was 27% smaller in children with diabetes (median 34.9 cm(3) ) than in controls (47.8 cm(3) ; P < 0.001). Pancreas volume correlated positively with age in controls (P = 0.033), but not in children with diabetes (P = 0.649). Pancreas volume did not correlate with diabetes duration, but it did correlate positively with units of insulin/kg body weight/day (P = 0.048). A linear model of pancreas volume as influenced by age, body surface area and insulin units/kg body weight/day found that insulin dosage correlated with pancreas volume after controlling for both age and body surface area (P = 0.009). Pancreatic fat fraction was not significantly different between the two groups (1.34% vs. 1.57%; P = 0.891). CONCLUSIONS Our findings do not indicate that pancreatic atrophy in Type 1 diabetes is associated with an increased pancreatic fat fraction, unlike some other diseases featuring reduced pancreatic volume. We speculate that our results may support the hypotheses that much of pancreatic atrophy in Type 1 diabetes occurs before the clinical onset of the disease and that exogenous insulin administration decelerates pancreatic atrophy after diabetes onset.

Abstract
A simple, sensitive and label-free optical sensor method was developed for allergens analysis using α-casein as the biomarker for cow's milk detection, to be used directly in final rinse samples of cleaning in place systems (CIP) of food manufacturers. A Surface Plasmon Resonance (SPR) sensor chip consisting of four sensing arrays enabling the measurement of samples and control binding events simultaneously on the sensor surface was employed in this work. SPR offers several advantages in terms of label free detection, real time measurements and superior sensitivity when compared to ELISA based techniques. The gold sensor chip was used to immobilise α-casein-polyclonal antibody using EDC/NHS coupling procedure. The performance of the assay and the sensor was first optimised and characterised in pure buffer conditions giving a detection limit of 58ngmL-1 as a direct binding assay. The assay sensitivity can be further improved by using sandwich assay format and amplified with nanoparticles. However, at this stage this is not required as the detection limit achieved exceeded the required allergens detection levels of 2µgmL-1 for α-S1-casein. The sensor demonstrated good selectivity towards the α-casein as the target analyte and adequate recoveries from CIP final rinse wash samples. The sensor would be useful tool for monitoring allergen levels after cleaning procedures, providing additional data that may better inform upon wider food allergen risk management decision(s) that are made by food manufacturer. In particular, this sensor could potentially help validate or optimise cleaning practices for a given food manufacturing process.
