Abstract
BACKGROUND Food allergy is considered a precursor to asthma in the context of the atopic march, but the relationship between infant food allergy phenotypes and lung function and asthma in childhood is unclear. We aimed to examine the association between food sensitisation and challenge-confirmed food allergy in infancy, as well as persistent and resolved food allergy up to age 6 years, and the risk of lung function deficits and asthma at age 6 years. METHODS The longitudinal, population-based HealthNuts cohort study in Melbourne, VIC, Australia, recruited 5276 infants children aged 1 year who attended council-run immunisation sessions between Sept 28, 2007, and Aug 5, 2011. At age 1 year, all children completed skin prick testing to four food allergens (egg, peanut, sesame, and either shrimp or cow's milk) and an oral food challenge (egg, peanut, and sesame) at the Royal Children's Hospital in Melbourne. Parents completed questionnaires about their infant's allergy history, demographic characteristics, and environmental exposures. At age 6 years, children were invited for a health assessment that included skin prick testing for ten foods (milk, egg, peanut, wheat, sesame, soy, shrimp, cashew, almond, and hazelnut) and eight aeroallergens (alternaria, cladasporum, house dust mite, cat hair, dog hair, bermuda grass, rye grass, and birch mix), oral food challenges, and lung function testing by spirometry. Questionnaires completed by parents (different to those completed at age 1 year) captured the child's allergy and respiratory history and demographics. We investigated associations between food allergy phenotypes (food-sensitised tolerance or food allergy; and ever, transient, persistent, or late-onset food allergy), lung function spirometry measures (forced expiratory volume in 1 sec [FEV1] and forced vital capacity [FVC] z-scores, FEV1/FVC ratio, forced expiratory flow at 25% and 75% of the pulmonary volume [FEF25-75%], and bronchodilator responsiveness), and asthma using regression methods. Only children with complete data on the exposure, outcome, and confounders were included in models. Infants without food sensitisation or food allergy at age 1 year and 6 years served as the reference group. FINDINGS Of 5276 participants, 3233 completed the health assessment at age 6 years and were included in this analysis. Food allergy, but not food-sensitised tolerance, at age 1 year was associated with reduced FEV1 and FVC (aβ -0·19 [95% CI -0·32 to -0·06] and -0·17 [-0·31 to -0·04], respectively) at age 6 years. Transient egg allergy was associated with reduced FEV1 and FVC compared with never having egg allergy (-0·18 [95% CI -0·33 to -0·03] and -0·15 [-0·31 to 0·00], respectively), whereas persistent egg allergy was not (FEV1 -0·09 [-0·48 to 0·31]; FVC -0·20 [-0·62 to 0·21]). Transient peanut allergy was associated with reduced FEV1 and FVC (FEV1 aβ -0·37 [-0·79 to 0·04] and FVC aβ -0·55 [-0·98 to -0·12]), in addition to persistent peanut allergy (FEV1 aβ -0·30 [-0·54 to -0·06] and FVC aβ-0·30 [-0·55 to -0·05]), and late-onset peanut allergy (FEV1 aβ -0·62 [-1·06 to -0·18] and FVC aβ-0·49 [-0·96 to -0·03]). Estimates suggested that food-sensitised tolerance and food allergy were associated with reduced FEF25-75%, although some estimates were imprecise. Food allergy phenotypes were not associated with an FEV1/FVC ratio. Late-onset peanut allergy was the only allergy phenotype that was possibly associated with increased risk of bronchodilator responsiveness (2·95 [95% CI 0·77 to 11·38]). 430 (13·7%) of 3135 children were diagnosed with asthma before age 6 years (95% CI 12·5-15·0). Both food-sensitised tolerance and food allergy at age 1 year were associated with increased asthma risk at age 6 years (adjusted odds ratio 1·97 [95% CI 1·23 to 3·15] and 3·69 [2·81 to 4·85], respectively). Persistent and late-onset peanut allergy were associated with higher asthma risk (3·87 [2·39 to 6·26] and 5·06 [2·15 to 11·90], respectively). INTERPRETATION Food allergy in infancy, whether it resolves or not, is associated with lung function deficits and asthma at age 6 years. Follow-up studies of interventions to prevent food allergy present an opportunity to examine whether preventing these food allergies improves respiratory health.

Abstract
This study presents findings from a qualitative study conducted in two relatively remote, primarily rural regions of the Canadian province of Quebec whose resource-based economic structures exacerbate inequalities between men and women. The purpose of this study was to understand how violence and homelessness intertwine in women's life courses in such regions. On the basis of past research showing that gender socialization around traditional roles and conservative values is particularly tenacious in non-urban areas, we conducted life-course interviews with 22 women in 13 different towns and villages of these two regions. Our content analysis of these interviews showed that specific social responses have forced women to maintain relationships with their aggressors or with people who have protected them, thus relegating these women's lives to the private sphere while reducing their opportunities for social participation in the public sphere. These social responses, together with women's economic and social disadvantages in these regions, were also the main factors that explain homelessness experienced by the participants in this study. Our analysis of these responses illustrates the patriarchal social structure of power in these regions, which is perpetuated in the interpersonal, institutional, and representational dimensions and keeps women in precarious, subordinate social positions, while ostracizing or punishing women who try to resist.

Abstract
Date Presented 03/31/2022
Infant massage is a beneficial intervention for infants with cardiac defects. No studies have explored how to promote parent engagement in infant massage with these fragile infants. The purpose of this study was to gain an understanding of parent and staff perceptions of infant massage for infants born with congenital heart defects. The results support the need for additional education about the purpose of infant massage, protocols, and how to safely deliver massage to critically ill infants.

Abstract
Although the association between child sexual abuse (CSA) and homelessness among women is well documented, few studies have investigated this topic from a feminist standpoint, examining the impact of sociocultural factors such as rape culture. Based on a qualitative life course approach, individual interviews were conducted with 21 women who experienced both CSA and homelessness. Participants were between 29 to 60 years old (M = 45 years of age). Analyses revealed that CSA disclosure experiences were characterized by victim-blaming and disbelief. Women's traumatic experiences were further aggravated by these types of reactions. Finally, CSA and negative social reactions to women's disclosures of CSA were perceived as the onset of social exclusion, which lead to their homelessness. This study shows how traumatic CSA experiences and negative social reactions to their disclosure can both contribute to social exclusion and isolation, and to homelessness through the internalization of rape myths. These findings support the importance of focusing on CSA prevention to reduce social exclusion and homelessness.

Abstract
Most of the research examining children visiting a parent in prison indicates that visits have a positive impact on children's well-being, their connection to the imprisoned parent and the parent themselves. However, the COVID-19 pandemic brought about a significant change to prison visits worldwide, with limits or bans on face-to-face contact. Understanding the experiences and needs of children during this period remains limited. This paper presents the findings of a survey of 84 carers of 184 children across Australia, investigating children's experiences of contact with their imprisoned parent both before and during COVID-19 restrictions. Although most carers reported maintaining contact during restrictions, a range of difficulties were noted: reduced availability; the effect of prison-based issues, including lockdowns; and the suitability of video/telephone visits for young children. Some described the benefits of videoconferencing, including reduced travel time and cost, and not needing to take children into a prison environment. Despite this, respondents typically described the negative impact of restrictions, and lack of physical contact, on children's emotional well-being. Our findings suggest that, for video visiting to be successful, it should be complementary to in-person visits, tailored to the needs of children, with support offered to families.

Abstract
Radio pulsars in short-period eccentric binary orbits can be used to study both gravitational dynamics and binary evolution. The binary system containing PSR J1141-6545 includes a massive white dwarf (WD) companion that formed before the gravitationally bound young radio pulsar. We observed a temporal evolution of the orbital inclination of this pulsar that we infer is caused by a combination of a Newtonian quadrupole moment and Lense-Thirring (LT) precession of the orbit resulting from rapid rotation of the WD. LT precession, an effect of relativistic frame dragging, is a prediction of general relativity. This detection is consistent with an evolutionary scenario in which the WD accreted matter from the pulsar progenitor, spinning up the WD to a period of <200 seconds.

Abstract
Fast radio bursts (FRBs) are brief radio emissions from distant astronomical sources. Some are known to repeat, but most are single bursts. Nonrepeating FRB observations have had insufficient positional accuracy to localize them to an individual host galaxy. We report the interferometric localization of the single-pulse FRB 180924 to a position 4 kiloparsecs from the center of a luminous galaxy at redshift 0.3214. The burst has not been observed to repeat. The properties of the burst and its host are markedly different from those of the only other accurately localized FRB source. The integrated electron column density along the line of sight closely matches models of the intergalactic medium, indicating that some FRBs are clean probes of the baryonic component of the cosmic web.

Abstract
Background Hemorrhage is a critical contributor to maternal morbidity but estimation of blood loss at delivery is frequently inaccurate. Due to this inaccuracy we sought to examine blood transfusion as a surrogate marker for morbidity in a large non-population based consecutive cohort. Methods A retrospective analysis of prospectively gathered data was carried out at two university institutions serving a heterogeneous urban obstetric population from January to December 2016. Data were analyzed to determine whether individual characteristics were associated with perinatal transfusion. Hematological indices and requirement for other blood products were also characterized. Results A total of 16,581 deliveries were recorded during the study and 1.7% (289/16,581) of the cohort required red cell transfusion. Those who received transfusion were more likely to be nulliparous, and to deliver <37 weeks' or >42 weeks' gestation. They were also more likely to have a macrosomic infant (birthweight >4 kg) and to have had a multiple pregnancy. Characteristics not associated with risk of transfusion included obesity [18% (52/289) vs. 15% (2445/16,292); P=0.18], and maternal age ≥35 years [28% (82/289) vs. 33% (5537/16,292); P=0.05]. Additional blood products were necessary in a small number of patients who received red cells. Conclusion The rate of transfusion in a contemporary Irish cohort has risen compared with previous data. Several variables associated with transfusion are consistent with older studies but importantly; maternal obesity and advanced maternal age are not associated with transfusion. These data may encourage the investment of resources in a population previously considered low-risk and, following future studies, to improve strategies aimed at limiting blood transfusion.

Abstract
Fast radio bursts (FRBs) are millisecond-duration events thought to originate beyond the Milky Way galaxy. Uncertainty surrounding the burst sources, and their propagation through intervening plasma, has limited their use as cosmological probes. We report on a mildly dispersed (dispersion measure 266.5 ± 0.1 parsecs per cubic centimeter), exceptionally intense (120 ± 30 janskys), linearly polarized, scintillating burst (FRB 150807) that we directly localize to 9 square arc minutes. On the basis of a low Faraday rotation (12.0 ± 0.7 radians per square meter), we infer negligible magnetization in the circum-burst plasma and constrain the net magnetization of the cosmic web along this sightline to <21 nanogauss, parallel to the line-of-sight. The burst scintillation suggests weak turbulence in the ionized intergalactic medium.

Abstract
This study investigates relationships between older prisoners' social experiences and their levels of distress. One hundred and seventy-three older prisoners (aged ≥ 50 years) from 8 Australian prisons were administered the Kessler Psychological Distress (K10) Scale, with additional information collected via individual interviews. Psychological distress scores were significantly associated with measures of self-reported safety (p < .001), prison victimization (p < .05), perceived social support from staff (p < .01) and inmates (p < .001), current employment (p < .05), and level of exercise (p < .001) among older inmates. Findings suggest that strategies for improving sense of safety, social support and level of exercise may ameliorate distress among older prisoners.

Abstract
In recent years, millisecond-duration radio signals originating in distant galaxies appear to have been discovered in the so-called fast radio bursts. These signals are dispersed according to a precise physical law and this dispersion is a key observable quantity, which, in tandem with a redshift measurement, can be used for fundamental physical investigations. Every fast radio burst has a dispersion measurement, but none before now have had a redshift measurement, because of the difficulty in pinpointing their celestial coordinates. Here we report the discovery of a fast radio burst and the identification of a fading radio transient lasting ~6 days after the event, which we use to identify the host galaxy; we measure the galaxy's redshift to be z = 0.492 ± 0.008. The dispersion measure and redshift, in combination, provide a direct measurement of the cosmic density of ionized baryons in the intergalactic medium of ΩIGM = 4.9 ± 1.3 per cent, in agreement with the expectation from the Wilkinson Microwave Anisotropy Probe, and including all of the so-called 'missing baryons'. The ~6-day radio transient is largely consistent with the radio afterglow of a short γ-ray burst, and its existence and timescale do not support progenitor models such as giant pulses from pulsars, and supernovae. This contrasts with the interpretation of another recently discovered fast radio burst, suggesting that there are at least two classes of bursts.

Abstract
BACKGROUND Radial arterial access (RA) and femoral arterial access (FA) rates for invasive coronary angiography (ICA) vary widely internationally. The European Society of Cardiology (ESC) suggests default RA is feasible. We aim to investigate the variation in RA rates across all New Zealand public hospitals. METHODS AND RESULTS Patient characteristics, procedural details, and inpatient outcome data were collected in the All New Zealand Acute Coronary Syndrome - Quality Improvement (ANZACS-QI) registry on consecutive patients undergoing ICA over five months. Of the 5894 ICAs 81% were via RA. Hospitals averaged 25 - 176 procedures/month (46.5% - 96.4% via RA). Operators averaged 17 procedures/month. Those performing more than 20 ICAs/month had RA rates between 61% - 99%. Of the 75 operators, 69% met the ESC recommendation. After multivariable adjustment higher operator (RR 1.12, CI 1.09 - 1.30) and hospital (RR 1.21, CI 1.15 - 1.28) volume were independent predictors of RA. Those with prior CABG (RR 0.51, CI 0.45 - 0.57), STEMI <12h (RR 0.91, CI 0.87 - 0.96), and female sex (RR 0.96, CI 0.94 - 0.99) were less likely to receive RA. CONCLUSIONS New Zealand has a high RA rate for ICAs. Rates vary substantially between both operators and centres. Radial arterial was highest amongst the highest volume operators and centres.

Abstract
We tested blood samples from men who have sex with men (MSM) to detect early HIV infection. Early HIV included both acute (infected past 30 days) and recent (estimated recency past 240 days). Acute infections were defined as screen immunoassay (IA) negative/NAAT-positive or IA-positive/Multispot-negative/NAAT-positive. Recent infections were defined as avidity index cutoff <30 % on an avidity-based IA and, (1) not reporting antiretroviral therapy use or, (2) HIV RNA >150 copies/mL. Of 937 samples, 26 % (244) were HIV-infected and of these 5 % (12) were early. Of early infections, 2 were acute and 10 recent; most (8/12) were among black MSM. Early infection was associated with last partner of black race [adjusted relative risk (ARR) = 4.6, confidence intervals (CI) 1.2-17.3], receptive anal sex at last sex (ARR = 4.3, CI 1.2-15.0), and daily Internet use to meet partners/friends (ARR = 3.3, CI 1.1-9.7). Expanding prevention and treatment for black MSM will be necessary for reducing incidence in the United States.

Abstract
BACKGROUND Non-attendance and inappropriate referrals affect the effective and efficient running of healthcare services. Non-engagement with speech and language therapy (SLT) services may lead to negative long-term consequences for children in need of SLT intervention. Currently there is a dearth of research on non-attendance and non-engagement with SLT services. AIMS To identify factors associated with (1) non-attendance and (2) parents' non-engagement with SLT services. METHODS & PROCEDURES Demographic data were collected from 140 case files of children (aged 5;0-17;11 years) discharged from a public community SLT service (November 2011-October 2013) with no intervention provided. Logistic regression analyses explored relationships between demographic data and (1) non-attendance and (2) non-engagement with the SLT service. OUTCOMES & RESULTS There was an increased probability of non-attendance during winter (i.e. September-February inclusive; OR = 3.14; p = 0.028) relative to summer, and with each month a child waited for SLT assessment (OR = 1.19; p = 0.066). There was decreased probability of non-attendance with children referred for speech (OR = 0.08; p = 0.011) or language difficulties (OR = 0.15; p = 0.050) relative to dysfluency. The probability of non-engagement with the SLT service increased in each of the following conditions: with each month a child waited for assessment (OR = 1.27; p = 0.004); in urban (OR = 2.40; p = 0.066) relative to rural locations; during winter (OR = 2.65; p = 0.021) relative to summer; and with referrals made by occupational therapists, physiotherapists, psychologists and social workers (OR = 18.65; p = 0.016) relative to doctor referrals. CONCLUSIONS & IMPLICATIONS Non-attendance is influenced by wait times, season and the reason for referral. Location (urban versus rural), referral source, wait times and season are factors related to non-engagement with SLT services. Targeted policies to improve efficiency and effectiveness of SLT services could be designed around these study findings.

Abstract
La violence conjugale est un problème social grave et persistant ; le tiers des femmes de la planète en a déjà été victime. Cet article vise à discuter des liens empiriques et théoriques entre les violences conjugales, familiales et structurelles. L’article débutera par une brève mise en contexte décrivant comment la violence conjugale s’est construite comme un problème socio-pénal au Québec. Les principales lacunes des connaissances actuelles dans le domaine seront ensuite identifiées, démontrant ainsi la nécessité de mieux comprendre les liens complexes entre les violences conjugales, familiales et structurelles, trois concepts dont les définitions pourraient s’enrichir et se compléter mutuellement. Cet article soulignera l’importance de prendre en considération les réalités diversifiées auxquelles sont confrontés les acteurs concernés par ces violences (femmes, hommes et enfants), en privilégiant une analyse globale qui intègre non seulement les facteurs individuels et interpersonnels, mais aussi les facteurs sociaux et structurels, notamment les oppressions liées au genre ou à d’autres marqueurs de l’identité sociale. La discussion sera enrichie par des modèles théoriques décrivant les différentes dynamiques de violences conjugales et familiales ainsi que par le féminisme intersectionnel, qui s’avère fort utile pour l’analyse des violences structurelles. La conclusion traitera des retombées potentielles d’une analyse des liens entre les violences conjugales, familiales et structurelles sur les politiques sociales et les programmes d’intervention pour les victimes, les agresseurs et les enfants exposés à la violence conjugale.

Abstract
A compendium of all the volatile organic compounds (VOCs) emanating from the human body (the volatolome) is for the first time reported. 1840 VOCs have been assigned from breath (872), saliva (359), blood (154), milk (256), skin secretions (532) urine (279), and faeces (381) in apparently healthy individuals. Compounds were assigned CAS registry numbers and named according to a common convention where possible. The compounds have been grouped into tables according to their chemical class or functionality to permit easy comparison. Some clear differences are observed, for instance, a lack of esters in urine with a high number in faeces. Careful use of the database is needed. The numbers may not be a true reflection of the actual VOCs present from each bodily excretion. The lack of a compound could be due to the techniques used or reflect the intensity of effort e.g. there are few publications on VOCs from blood compared to a large number on VOCs in breath. The large number of volatiles reported from skin is partly due to the methodologies used, e.g. collecting excretions on glass beads and then heating to desorb VOCs. All compounds have been included as reported (unless there was a clear discrepancy between name and chemical structure), but there may be some mistaken assignations arising from the original publications, particularly for isomers. It is the authors' intention that this database will not only be a useful database of VOCs listed in the literature, but will stimulate further study of VOCs from healthy individuals. Establishing a list of volatiles emanating from healthy individuals and increased understanding of VOC metabolic pathways is an important step for differentiating between diseases using VOCs.

Abstract
Molecular medicine is transforming modern clinical practice, from diagnostics to therapeutics. Discoveries in research are being incorporated into the clinical setting with increasing rapidity. This transformation is also deeply changing the way we practise pathology. The great advances in cell and molecular biology which have accelerated our understanding of the pathogenesis of solid tumours have been embraced with variable degrees of enthusiasm by diverse medical professional specialties. While histopathologists have not been prompt to adopt molecular diagnostics to date, the need to incorporate molecular pathology into the training of future histopathologists is imperative. Our goal is to create, within an existing 5-year histopathology training curriculum, the structure for formal substantial teaching of molecular diagnostics. This specialist training has two main goals: (1) to equip future practising histopathologists with basic knowledge of molecular diagnostics and (2) to create the option for those interested in a subspecialty experience in tissue molecular diagnostics to pursue this training. It is our belief that this training will help to maintain in future the role of the pathologist at the centre of patient care as the integrator of clinical, morphological and molecular information.

Abstract
Acute leukaemias are relatively common malignancies. Treatment has advanced significantly in the recent past and there has been improved patient survival. This improved initial response is leading to an increasing number of cases of relapse. Extramedullary relapse occurs in a wide variety of locations with varying presentations, imaging findings and differentials. The pathophysiology and clinical course of recurrent extramedullary myeloid and lymphocytic leukaemias are reviewed in this article. The wide variety of imaging findings associated with many important sites of recurrence and the associated differential diagnosis are discussed and illustrated.

Abstract
BACKGROUND Growing pains (GP) is a prevalent familial childhood disorder of unknown aetiology. Familial occurrence of GP, and individual and familial association of GP with restless legs syndrome (RLS) has been reported. METHODS We applied a twin family design to search for evidence of genetic susceptibility to GP, and for a genetic relationship between GP and RLS. The parents of 1843 twin pairs aged 3-16 years were administered a questionnaire, which identified 88 pairs with at least one twin individual fulfilling criteria for GP. Standard questionnaires for history of GP and RLS were completed for these twin pairs, their siblings and parents. RESULTS Twenty-five of 34 monozygotic (MZ) pairs were concordant for GP, compared with 12 of the 54 dizygotic (DZ) pairs. The casewise concordance was 0.85 and 0.36 for MZ and DZ pairs, respectively (p < 0.001). The lifetime GP prevalence for relatives of twins with GP was 51% for non-twin siblings, 47% for parents. Twenty-three percent of twin individuals with GP met RLS criteria compared with 8% of twin individuals without GP (p = 0.03). Of the twins with GP concordance, 19% met RLS criteria compared with 2% of twins with GP discordance (p = 0.01). In two MZ pairs, one had GP and the other RLS. The lifetime prevalence of RLS was 40% for mothers, and 24% for fathers and 18% for non-twin siblings. CONCLUSION This first twin family study of GP provides evidence for a genetic aetiology and for a genetic relationship to RLS.

Abstract
BACKGROUND Bone marrow has been shown to be superior to peripheral blood, as a stem cell source, in young patients (<20 years of age) with acquired aplastic anemia undergoing a matched sibling transplant. The aim of this study was to test whether this currently also holds true for older patients with acquired aplastic anemia. DESIGN AND METHODS We analyzed 1886 patients with acquired aplastic anemia who received a first transplant from a human leukocyte antigen identical sibling between 1999 and 2009, with either bone marrow (n=1163) or peripheral blood (n=723) as the source of stem cells. RESULTS In multivariate Cox analysis negative predictors for survival were: patient's age over 20 years (RR 2.0, P<0.0001), an interval between diagnosis and transplantation of more than 114 days (RR 1.3, P=0.006), no anti-thymocyte globulin in the conditioning (RR 1.6, P=0.0001), a conditioning regimen other than cyclophosphamide (RR=1.3, P=0.008) and the use of peripheral blood as the source of stem cells (RR 1.6, P<0.00001). The survival advantage for recipients of bone marrow rather than peripheral blood was statistically significant in patients aged 1-19 years (90% versus 76% P<0.00001) as well as in patients aged over 20 years (74% versus 64%, P=0.001). The advantage for recipients of bone marrow over peripheral blood was maintained above the age of 50 years (69% versus 39%, P=0.01). Acute and chronic graft-versus-host disease were more frequent in peripheral blood transplants. Major causes of death were graft-versus-host disease (2% versus 6% in bone marrow and peripheral blood recipients, respectively), infections (6% versus 13%), and graft rejection (1.5% versus 2.5%). CONCLUSIONS This study shows that bone marrow should be the preferred stem cell source for matched sibling transplants in acquired aplastic anemia, in patients of all age groups.

Abstract
Abstract
Background: Ductal Intraepithelial Neoplasia [DIN] often shows heterogeneity of both morphology and nuclear grade within the same patient. It is unknown whether this implies heterogeneity with respect to hormone receptor status that may affect treatment. We sought to determine the rate of heterogeneity in terms of nuclear grade and receptor status in DIN patients.
Methods: A hospital tumor registry was queried for patients diagnosed with DIN between 1980 and 2010. Of the 746 patients identified, 579 (77.6%) had a concomitant invasive tumor. Of the remaining 167 patients, 70 were diagnosed prior to 2007 (when ASCO-CAP guidelines for hormone receptor measurements were released), 2 were found to have lobular intraepithelial neoplasia rather than DIN, and in 11 cases, pathology slides were not available for review. Of the 84 remaining patients with DIN, 17 (20.2%) had DIN 1 alone, 19 (22.6%) had DIN 2 alone, and 7 (8.3%) had DIN 3 alone. 41 (48.8%) of the patients had more than one grade of DIN. These patients formed the cohort of interest. Slides were reviewed by a single pathologist who evaluated ER and PR positivity within the different grades of DIN in each patient, classifying tumors staining 1% or greater as positive. Statistical analyses were performed using SPSS.
Results: The median patient age was 53 years old. Of the 41 patients with multiple grades of DIN, 32 (78.0%) had DIN 1 and 2, 6 (14.6%) had DIN 2 and 3, and 3 (7.3%) had DIN 1, 2, and 3 within the same tumor. 93.8%, 94.7% and 88.9% of DIN 1, 2 and 3 lesions respectively were ER-positive. A difference in hormone receptor status between different grades of DIN within the same tumor was noted in 12 (29.3%) of patients; of these 3 (10.3%) varied in ER status and 10 (34.5%) varied in PR status. Of the 2 patients with ER-negative DIN 1, both had ER-positive higher grade DIN within the same tumor. Of the 2 patients with ER-negative DIN 2, one had ER-positive DIN 1 while the other had ER-negative DIN 3. Therefore, of the total 41 patients, 40 (97.6%) had at least one component of DIN that was ER-positive, and evaluating more than one grade of DIN for ER allowed 75% of patients with at least one ER-negative component to be offered hormonal therapy.
Conclusions: Nearly 50% of patients with DIN will have more than one nuclear grade in the same tumor. These different nuclear grades vary in hormone receptor status in approximately 30% of patients. The majority of patients (97.6%) have at least one component of their DIN that is ER-positive. For those who have at least one component that is ER-negative, up to 75% may be offered hormonal therapy by considering other grades of DIN in treatment decision-making.

Abstract
Doping of Si nanocrystals is an important topic in the emerging field of Si nanocrystals based all-Si tandem solar cells. Boron-doped Si nanocrystals embedded in a silicon dioxide matrix were realized by a co-sputtering process, followed by high temperature annealing. The x-ray photoelectron spectroscopy B 1s signal attributable to Si-B (187 eV) and/or B-B (188 eV) indicates that the boron may exist inside Si nanocrystals. A higher probability of effective boron doping was suggested for Si-rich oxide films with a low oxygen content, Then, structural and optical properties were characterized with a focus on the effects of the boron content on Si quantum dots. The results show that as the boron content increases, the nanocrystal size is slightly reduced and the Si crystallization is suppressed. The photoluminescence intensity of the films is decreased as the boron content increases. This is due to boron-induced defects and/or Auger processes induced by effective doping. These results can provide optimal conditions for future Si quantum dot based solar cells.

Abstract
PURPOSE Reports investigating whether the response rates to palliative radiation therapy (RT) for painful bone metastases from gastrointestinal (GI) cancers are similar to rates for bone metastases from other primary cancer sites have been limited. The present study evaluated response rates for symptomatic bone metastases from gi cancers after palliative outpatient rt in the Rapid Response Radiotherapy Program (RRRP). PATIENTS AND METHODS We identified 69 patients with bone metastases from gi primaries who received palliative rt in the RRRP clinic during 1999-2006. We extracted records for 31 of these patients during 1999-2003 from an RRRP database that used the Edmonton Symptom Assessment Scale (ESAS). Record for the remaining 38 patients during 2003-2006 were extracted from an RRRP database that used the Brief Pain Inventory (BPI). Eligibility criteria for encryption in the two RRRP databases and for collection of patient demographic information (age, sex, primary cancer site, and Karnofsky performance status) were identical. Response rates for this cohort of metastatic gi patients were then compared to rates for 479 patients receiving palliative RT for bone metastases from other primary cancer sites. Pain scores from the ESAS and BPI and data on analgesic consumption were collected at baseline and by telephone follow-up at 4, 8, and 12 weeks after RT for all patients. Complete (CR), partial (PR), and overall (CR+PR) responses were evaluated according to International Consensus Endpoints. RESULTS Assessment of the 69 patients with metastatic GI cancers revealed CR, PR, and CR+PR rates of 18%, 42%, and 61% at 4 weeks; 22%, 35%, and 57% at 8 weeks; and 50%, 21%, and 71% at 12 weeks for evaluable patients. The 479 evaluable patients with metastatic cancer from other primary cancer sites had CR, PR, and CR+PR rates of 25%, 27%, and 51% at 4 weeks; 26%, 22%, and 48% at 8 weeks; and 22%, 29%, and 51% at 12 weeks. No statistically significant differences were observed in RT response rates for bone metastases from GI cancers than from other primary cancer sites. CONCLUSIONS After palliative RT, bone metastases from gi cancers demonstrate response rates that are similar to rates for metastases from other primary cancer sites. Patients with symptomatic bone metastases from GI malignancies should be referred for palliative RT as readily as patients with osseous metastases from other primary cancer sites.
