RESUMO
BACKGROUND: Much interest has been focussed on both maternal obesity and gestational weight gain (GWG), particularly on their role in influencing birth weight (BW). Several large reviews have reported that excessive GWG is associated with an increase in BW. However recent large, well-designed, randomized controlled trials studying interventions aimed at reducing GWG have all consistently failed to show a reduction in BW despite achieving a reduction in GWG. The aim of this longitudinal prospective study was to examine the relationship between GWG and birth weight in women where GWG and Body Mass Index (BMI) were measured accurately in a strictly standardized way. METHODS: Women were enrolled at their convenience before 18 weeks gestation. Height and weight were measured accurately at the first antenatal visit and BMI calculated. Maternal weight was measured again after 37 weeks gestation. The weight of the baby was measured at birth. Relationships were tested using linear regression analysis, chi-squared tests and t-tests as appropriate. RESULTS: Of the 522 women studied, the mean BMI was 25.3 kg/m2 and 15.7% were obese. The mean BW at term was 3576 g (2160-5120) and 2.7% (n = 14) weighed ≥4500 g. The mean GWG overall was 12.3 kg (4.6 to 28.4) and GWG decreased as BMI increased. The mean GWG was less in obese women, at 8.7 kg (- 4.6 to 23.4), compared to non-obese,13.0 kg (0.6-28.4) (p < 0.001). Mean BW in obese women was 3630 g vs 3565 g in non-obese (p = 0.27). The total GWG correlated positively with BW (p < 0.001). When BW was subtracted from total GWG, GWG no longer correlated with BW (p = 0.12). CONCLUSIONS: The positive correlation between GWG in pregnancy and BW can be accounted for by the contribution of fetal weight to GWG antenatally without a contribution from increased maternal adiposity. There was a wide range of BW irrespective of the degree of GWG and obese women had a lower GWG than non-obese women. These findings help explain why Randomized Controlled Trials (RCTs) designed to reduce GWG have failed to decrease BW and suggest there is no causative link between excessive GWG and increased BW.

AIM: The aim of this research is to establish if variation exists in the dose delivered for head and neck (HN) localisation computed tomography (CT) imaging in radiation therapy (RT); to propose a national diagnostic reference levels (DRLs) for this procedure and to make a comparison between the national DRL and a DRL of a European sample. BACKGROUND: CT has become an indispensable tool in radiotherapy (RT) treatment planning. It is a requirement of legislation in many countries that doses of ionising radiation for medical exposures be kept 'As Low As Reasonably Achievable'. There are currently no dose guidelines for RT localisation CT of the HN. MATERIALS AND METHODS: All RT departments in Ireland and a sample of European departments were surveyed. Dose data on CT dose length product (DLP); dose index volume (CTDIvol); current time product; tube voltage and scan length was acquired for ten average-sized HN patients from each department. DRLs were proposed for DLP and CTDIvol using the rounded 75th percentile of the distribution of the means. RESULTS: 42% of Irish departments and one European department completed the survey. Significant variation was found in the mean DLP, CTDIvol and scan lengths across the Irish departments. The proposed Irish DRL is 882 mGy cm and 21 mGy and the European department DRL is 816 mGy cm and 21 mGy, for DLP and CTDIvol, respectively. CONCLUSIONS: Variation exists in doses used for HN RT localisation CT. DRLs have been proposed for comparison purposes with the aim of dose optimisation.
RESUMO
BACKGROUND: Craniospinal irradiation (CSI) is the standard radiation therapy treatment for medulloblastoma. Conventional CSI photon therapy (Photon-CSI) delivers significant dose to surrounding normal tissue (NT). Research into pediatric CSI with proton therapy (Proton-CSI) has increased, with the aim of exploiting the potential to reduce NT dose and associated post-treatment complications. This review aims to compare treatment outcomes of pediatric medulloblastoma patients between Proton- and Photon-CSI treatments. MATERIAL AND METHODS: A search and review of studies published between 1990 and 2016 comparing pediatric (2-18 years) medulloblastoma Proton- and Photon-CSI in three aspects - normal organ sparing and target coverage; normal organ dysfunction and second malignancy risks - was completed. RESULTS: Fifteen studies were selected for review and the results were directly compared. Proton-CSI reported improved out-of-field organ sparing while target coverage improvements were inconsistent. Normal organ dysfunction risks were predicted to be lower following Proton-CSI. Secondary malignancy risks (SMRs) were generally lower with Proton-CSI based on several different risk models. CONCLUSIONS: Proton-CSI conferred better treatment outcomes than Photon-CSI for pediatric medulloblastoma patients. This review serves to compare the current literature in the absence of long-term data from prospective studies.

OBJECTIVE: To provide accurate estimates of the commencement time, duration and dosage of folic acid (FA) supplementation taken by Irish women in the periconceptional period. The study also aimed to establish the factors associated with optimal FA supplementation practices. DESIGN: Cross-sectional observational study. Women's clinical and sociodemographic details were computerised. Maternal weight and height were measured before calculating BMI. Detailed FA supplementation questionnaires were completed under the supervision of a trained researcher. SETTING: A large university maternity hospital, Republic of Ireland, January 2014-April 2016. SUBJECTS: Women (n 856) recruited at their convenience in the first trimester. RESULTS: While almost all of the women (97 %) were taking FA at enrolment, only one in four women took FA for at least 12 weeks preconceptionally (n 208). Among the 44 % of women who were supplementing with FA preconceptionally, 44 % (162/370) reported taking FA for less than the 12 weeks required to achieve optimal red-blood-cell folate levels for prevention of neural tube defects. On multivariate analysis, only planned pregnancy and nulliparity were associated with taking FA for at least 12 weeks preconceptionally. Among women who only took FA postconceptionally, almost two-thirds commenced it after day 28 of their pregnancy when the neural tube had already closed. CONCLUSIONS: As the timing of FA was suboptimal both before and after conception, we recommend that current national FA guidelines need to be reviewed.

Background: The aim of this observational study was to measure food, macronutrient and micronutrient intakes of women presenting for antenatal care and assess compliance with current nutritional recommendations. Methods: Women were recruited in the first trimester of pregnancy. Maternal weight and height were measured and body mass index (BMI) calculated. Body composition was measured using bioelectrical impedance analysis. Maternal energy and nutrient intakes were estimated using a validated Willett Food Frequency Questionnaire and misreporting of energy intakes (EI) determined. Results: Plausible EIs were reported in 402 women. Mean age, weight and BMI were 30.8 years, 67.1 kg and 24.6 kg/m2 respectively. Median EIs were 2111 kcal, and median protein, carbohydrate and fat intakes were 17.3, 48.1 and 36.2 g/MJ/day, respectively. More than 90% of women exceeded the recommended daily allowance for saturated fat. Nearly all of the women (99%) did not meet estimated average requirements (EAR) for vitamin D. One in three women failed to achieve a dietary folate intake of 400 µg/day. Over one in five women failed to meet the EAR for iron, and 14% failed to achieve the EAR for calcium. Conclusions: Our findings highlight concerning deficits in nutrient intakes among women and will help guide professional dietary advice to women attending for future obstetric care in Ireland.

OBJECTIVE: We examined whether breast-feeding, and in particular exclusive breast-feeding, was associated with maternal weight and body composition changes at 4 months postpartum independently of other maternal variables. DESIGN: Prospective longitudinal study. Women were recruited in the first trimester after an ultrasound examination confirmed an ongoing singleton pregnancy. Weight and body composition were measured using advanced bio-electrical impedance analysis at the first antenatal visit and 4 months postpartum. Detailed questionnaires were completed on breast-feeding, socio-economic status, diet and exercise in addition to routine clinical and sociodemographic details. SETTING: Large Irish university maternity hospital. SUBJECTS: Women who delivered a baby weighing ≥500 g between November 2012 and March 2014. RESULTS: At the postpartum visit, the mean weight was 70·9 (sd 14·2) kg (n 470) and the mean BMI was 25·9 (sd 5·0) kg/m2. 'Any breast-feeding' was reported by 65·1 % of women (n 306). Irish nativity (OR=0·085, P<0·001), current smoking (OR=0·385, P=0·01), relative income poverty (OR=0·421, P=0·04) and deprivation (OR=0·458, P=0·02) were negatively associated with exclusive breast-feeding. At 4 months postpartum there was no difference in maternal weight change between women who exclusively breast-fed and those who formula-fed (+2·0 v. +1·1 kg, P=0·13). Women who exclusively breast-fed had a greater increase in percentage body fat at 4 months postpartum compared with women who formula-fed (+1·0 v. -0·03 %, P=0·02), even though their dietary quality was better. Exclusive breast-feeding was not associated with postpartum maternal weight or body fat percentage change after adjusting for other maternal variables. CONCLUSIONS: There are many reasons why breast-feeding should be strongly promoted but we found no evidence to support postpartum weight management as an advantage of breast-feeding.

BACKGROUND: Neural tube defects (NTDs) are major congenital malformations that are potentially preventable if the woman takes periconceptional folic acid (FA) supplements. A recent report found that NTD incidence had increased in Ireland. This study examined the usage of FA supplementation in women presenting for antenatal care in a maternity hospital. METHODS: Women were recruited at their convenience in the first trimester. Their clinical and sociodemographic details were computerized. Maternal weight and height were measured before calculating body mass index. Detailed FA questionnaires were completed under supervision of a trained researcher. RESULTS: While 96.1% (n = 564) out of 587 reported that they took FA after they became pregnant, only 24.7% (n = 145) took it for >12 weeks preconceptionally as recommended. Only 5.7% (n = 6) of obese women took high-dose FA as recommended. On univariate analysis, the strongest predictors of preconceptional FA usage were higher maternal age, higher education and income, being married, being nulliparous, not smoking, infertility treatment and planned pregnancy. On multivariate analysis, both planned pregnancy and nulliparity were the most important predictors of preconceptional FA use. CONCLUSIONS: Our study shows that current recommendations to prevent NTDs by FA supplementation pre-pregnancy are not being fully implemented in Ireland. We recommend a review of current public health policies on FA supplementation.

BACKGROUND: The purpose of this cross-sectional study was to examine periconceptional misreporting of energy intake (EI) using the Willet food frequency questionnaire (WFFQ). METHODS: Women were recruited in the first trimester. Women completed a semi-quantitative WFFQ. Maternal body composition was measured using eight-electrode bioelectrical impedance analysis. Under-reporters were those whose ratio of EI to their calculated basal metabolic rate fell below the calculated plausible threshold for their physical activity category. RESULTS: The mean age was 30.1 ± 5.3 years (n = 524). The mean body mass index (BMI) was 25.4 ± 5.6 kg/m(2), and 16.6% were obese (BMI ≥ 30.0 kg/m(2)). Under-reported EI was observed in 122 women (23.3%) with no over-reporters in the sample. Under-reporters were younger (P < 0.001), less likely to have a normal BMI (P = 0.002) and more likely to be obese (P < 0.001) than plausible reporters. Under-reporters had higher percentage of body-fat and lower percentage of body fat-free mass (P < 0.001), were more likely to be at risk of relative deprivation (P = 0.001) and reported a higher percentage of EI from carbohydrate (P = 0.02) than plausible reporters. CONCLUSIONS: Observed differences between under-reporters and plausible reporters suggest that the exclusion of these under-reporters represents an important potential source of bias in obesity research among women in the periconceptional period.

OBJECTIVE: This longitudinal study compared changes in maternal weight and body mass index (BMI) in early pregnancy in the time interval between when a woman first attended for antenatal care with her first child and when she next attended for antenatal care. STUDY DESIGN: We studied women with a singleton pregnancy who delivered their first baby weighing ≥ 500 g in 2009 and who attended again for antenatal care with an ongoing pregnancy before January 1, 2012. Maternal weight and height were measured before 18 weeks' gestation in both pregnancies and BMI was calculated. RESULTS: Of the 3,284 primigravidas, the mean weight at the first visit in 2009 was 66.4 kg (standard deviation [SD] 12.7). The mean BMI was 24.5 kg/m(2) (SD 4.6), and 11.3% (n = 370) were obese. Of the 3,284 women, 1,220 (37.1%) re-attended for antenatal care before 2012 after sonographic confirmation of an ongoing pregnancy. Of the 1,220 women who re-attended, 788 (64.6%) had gained weight (mean 4.6 kg [SD 3.9]), 402 (33%) had lost weight (mean 3 kg [SD 2.9]), and 30 (2.4%) had maintained their weight. CONCLUSION: The birth of a first baby was associated with an increase in maternal weight in two-thirds of women when they next attended for antenatal care.

The aim of this article is to review the current evidence on gestational weight gain (GWG). Maternal obesity has emerged as one of the great challenges in modern obstetrics as it is becoming increasingly common and is associated with increased maternal and fetal complications. There has been an upsurge of interest in GWG with an emphasis on the relationship between excessive GWG and increased fetal growth. Recent recommendations from the Institute of Medicine in the USA have revised downwards the weight gain recommendations in pregnancy for obese mothers. We believe that it is time to take stock again about the advice that pregnant women are given about GWG and their lifestyle before, during, and after pregnancy. The epidemiological links between excessive GWG and aberrant fetal growth are weak, particularly in obese women. There is little evidence that intervention studies decrease excessive GWG or improve intrauterine fetal growth. Indeed, there is a potential risk that inappropriate interventions during the course of pregnancy may lead to fetal malnutrition that may have adverse clinical consequences, both in the short- and long-term. It may be more appropriate to shift the focus of attention from monitoring maternal weight to increasing physical activity levels and improving nutritional intakes.

Purpose: The COVID-19 pandemic had a substantial effect on mental health and work productivity of early-career researchers working in Radiation Oncology (RO). However, the underlying mechanisms of these effects are unclear. The aim of the current qualitative study was therefore to achieve a better understanding of how these effects arose and could be managed in the future. Methods: This study was conducted jointly by RO and qualitative health researchers. Data was collected in four online Focus Groups with 6-11 RO researchers (total N = 31) working in Europe. The transcripts were analysed through a qualitative cross-impact analysis. Results: Causal relations were identified between seventeen variables that depict the impact of disrupted working conditions. Mental health and work productivity were indeed the most important affected variables, but relations between variables towards these impacts were complex. Relations could either be positive or negative and direct or indirect, leading to a cascade of interrelated events which are highly personal and could change over time. We developed the model 'impact of disrupted working conditions' depicting the identified variables and their relations, to allow more individual assessment and personalised solutions. Conclusion: The impacts of disrupted working conditions on RO researchers varied due to the complexity of interrelated variables. Consequently, collective actions are not sufficient, and a more personal approach is needed. Our impact model is recommended to help guide conversations and reflections with the aim of improving work/life balance. The participants showed high levels of personal responsibility towards their own mental health and work productivity. Although being an individual issue, a collective responsibility in developing such approaches is key due to the dependency on organizational variables.
RESUMO
BACKGROUND AND PURPOSE: Cancer care can be taxing. Alexithymia, a personality construct characterized by difficulties in identifying and describing feeling and emotions, an externally-oriented thinking style and scarcity of imagination and fantasy, is significantly correlated with higher levels of both secondary traumatic stress (STS) and burnout and lower levels of compassion satisfaction in medical professionals in radiation oncology. In this study, we aimed to assess the difference in professional quality of life (QoL) and the association with alexithymia in this multidisciplinary field depending on the specific profession (radiation/clinical oncologist, RO; medical physicist, MP; radiation therapist, RTT). MATERIAL AND METHODS: The study was conducted via an online questionnaire, receiving 1500 submissions between May and October 2018. Alexithymia was assessed via the Toronto Alexithymia Scale (TAS-20) and professional QoL was evaluated using the Professional Quality of Life Scale (ProQoL) version 5. Comparisons between the RO, RTT, and MP groups were performed by ANOVA or MANOVA, followed by Bonferroni corrected ANOVAs for continuous variables, and Pearson's chi-square test for categorical variables. The effect size was determined by calculating partial eta-squared (η2). RESULTS: Profession had a moderator role on the correlation between alexithymia and STS, with RO being at a higher risk than MP and RTT. Further, the results of this study demonstrate the relevant point prevalence of decreased well-being at work even for professional categories such as MP despite the more technical profile and reduced interaction with patients. CONCLUSIONS: This study demonstrates the importance of alexithymia as a factor contributing to decreased professional QoL amongst radiation oncology professionals. Alexithymic ROs are impacted to a higher extent compared to MPs and RTTs by the indirect exposure to patients suffering. It is worth addressing these observations in professional education, aiming to improve QoL for healthcare personnel.

BACKGROUND AND PURPOSE: Different factors may influence the professional quality of life of oncology professionals. Among them, personality traits, as alexithymia and empathy, are underinvestigated. Alexithymia is about deficits in emotion processing and awareness. Empathy is the ability to understand another's 'state of mind'/emotion. The PROject on BurnOut in RadiatioN Oncology (PRO BONO) assesses professional quality of life, including burnout, in the field of radiation oncology and investigates alexithymia and empathy as contributing factors. MATERIAL AND METHODS: An online survey was conducted amongst ESTRO members. Participants completed 3 validated questionnaires for alexithymia, empathy and professional quality of life: (a) Toronto Alexithymia Scale; (b) Interpersonal Reactivity Index; (c) Professional Quality of Life Scale. The present analysis, focusing on radiation/clinical oncologists, evaluates Compassion Satisfaction (CS), Secondary Traumatic Stress (STS) and Burnout and correlates them with alexithymia and empathy (empathic concern, perspective taking and personal distress) with generalized linear modeling. Significant covariates on univariate linear regression analysis were included in the multivariate linear regression model. RESULTS: A total of 825 radiation oncologists completed all questionnaires. A higher level of alexithymia was associated to decreased CS (ß: -0.101; SE: 0.018; p < 0.001), increased STS (ß: 0.228; SE: 0.018; p < 0.001) and burnout (ß: 0.177; SE: 0.016; p < 0.001). A higher empathic concern was significantly associated to increased CS (ß: 0.1.287; SE: 0.305; p = 0.001), STS (ß: 0.114; SE: 0.296; p < 0.001), with no effect on burnout. Personal distress was associated to decreased CS (ß: -1.423; SE: 0.275; p < 0.001), increased STS (ß: 1.871; SE: 0.283; p < 0.001) and burnout (ß: 1.504; SE: 0.245; p < 0.001). CONCLUSIONS: Alexithymic personality trait increased burnout risk, with less professional satisfaction. Empathic concern was associated to increased stress, without leading to burnout, resulting in higher professional fulfillment. These results may be used to benchmark preventing strategies, such as work-hour restrictions, peer support, debriefing sessions, and leadership initiatives for professionals at risk.

BACKGROUND AND PURPOSE: Physical and mental well-being are crucial for oncology professionals as they affect performance at work. Personality traits, as alexithymia and empathy, may influence professional quality of life. Alexithymia involves diminished skills in emotion processing and awareness. Empathy is pertinent to the ability to understand another's 'state of mind/emotion'. The PROject on Burn-Out in RadiatioN Oncology (PRO BONO) investigates professional quality of life amongst radiation oncology professionals, exploring the role of alexithymia and empathy. The present study reports on data pertinent to radiation therapists (RTTs). MATERIAL AND METHODS: An online survey targeted ESTRO members. Participants were asked to fill out 3 questionnaires for alexithymia, empathy and professional quality of life: (a) Toronto Alexithymia Scale (TAS-20); (b) Interpersonal Reactivity Index (IRI); (c) Professional Quality of Life Scale (ProQoL). The present analysis focuses on RTTS to evaluate compassion satisfaction (CS), secondary traumatic stress (STS) and Burnout and their correlation with alexithymia and empathy, using generalized linear modeling. Covariates found significant at univariate linear regression analysis were included in the multivariate linear regression model. RESULTS: A total of 399 RTTs completed all questionnaires. The final model for the burnout scale of ProQoL found, as significal predictors, the TAS-20 total score (ßâ¯=â¯0.46, pâ¯<â¯0 0.001), and the individual's perception of being valued by supervisor (ßâ¯=â¯-0.29, pâ¯<â¯0.001). With respect to CS, the final model included TAS-20 total score (ßâ¯=â¯-0.33, pâ¯<â¯0.001), the Empatic Concern domain (ßâ¯=â¯0.23, pâ¯<â¯0.001) of the IRI questionnaire and the individual's perception of being valued by colleagues (ßâ¯=â¯0.22, pâ¯<â¯0.001). CONCLUSIONS: Alexithymia increased the likelyhood to experience burnout and negatively affected the professional quality of life amongst RTTs working in oncology. Empathy resulted in higher professional fulfillment together with collegaues' appreciation. These results may be used to benchmark preventing strategies and implement organization-direct and/or individual-directed interventions.
RESUMO
BACKGROUND AND PURPOSE: The professional quality of life of radiation oncology professionals can be influenced by different contributing factors, including personality traits. Alexithymia involves deficits in emotion processing and awareness. Empathy is the ability to understand another's 'state of mind/emotion'. We investigated professional quality of life, including burnout, in radiation oncology, exploring the role of alexithymia and empathy and targeting the population of medical physicists (MPs), since this professional category is usually underrepresented in surveys exploring professional well-being in radiation oncology and MPs may experience professional distress given the increasing complexity of multimodal cancer care. MATERIAL AND METHODS: An online survey was addressed to ESTRO members. Participants filled out three questionnaires to evaluate alexithymia, empathy and professional quality of life: a) Toronto Alexithymia Scale (TAS-20); b) Interpersonal Reactivity Index (IRI); c) Professional Quality of Life Scale (ProQoL). Professional quality of life as per ProQoL was considered as dependent variable. The three domains of the ProQoL, namely compassion satisfaction (CS), secondary traumatic stress (STS) and burnout were correlated with alexithymia (as per TAS-20) and empathy (as per IRI with three subcategories: empathic concern, perspective taking and personal distress) and demographic/professional characteristics as independent variables. Generalized linear modeling was used. Significant covariates on univariate linear regression analysis were included in the multivariate linear regression model. RESULTS: A total of 308 medical physicists completed all questionnaires. Alexithymia as per TAS-20 was correlated to decreased CS (ß = -0.25, p < 0 0.001), increased likelihood for STS (ß = 0.26, p < 0 0.001) and burnout (ß = 0.47, p < 0 0.001). With respect to empathy, the 'Empatic Concern' subscale of the IRI was found to be a significant predictor for increased CS (ß = 0.19, p = 0 0.001) and increased STS (ß = 0.19, p < 0 0.001), without significant correlation with burnout. The individual's perception of being valued by own's supervisor was correlated to increased CS (ß = 0.23, p < 0.001), and decreased burnout (ß = -0.29, p < 0.001). CONCLUSIONS: Alexithymic personality trait increased the likelihood to develop burnout, with less professional satisfaction amongst MPs working in radiation oncology. Empathy results in higher professional fulfilment. These results may be used to benchmark preventing strategies, including peer support, debriefing sessions, leadership initiatives and work-load limitation strategies.
RESUMO
INTRODUCTION: While Computerised Tomography (CT) remains the gold standard in radiation therapy (RT) planning, inferior soft tissue definition remains a challenge. Intravenous contrast (IVC) use during CT planning can enhance soft tissue contrast optimising Target Volume (TV) and Organ at Risk visualisation and delineation. Despite this known benefit, there are no guidelines for when and how to use IVC in RT planning scans in Ireland. AIM: The study aims to examine the patterns of practice in relation to the use of IVC in RT planning scans in Ireland and to determine the level of compliance with international guidelines. Radiation Therapists (RTT) IVC training will also be investigated. MATERIALS AND METHODS: An anonymised online survey was designed based on previously-reported literature. This was distributed to all RT departments in Ireland. The survey contained open, closed and Likert scale questions that investigated IVC practices in each department. RESULTS: 75% (nâ¯=â¯9/12) of Irish departments responded. All responding departments reported using IVC. RTTs cannulated patients in 67% (nâ¯=â¯6/9) of the departments and administration contrast in all departments. Variations from recommended guidelines were found in disease sites where IVC was routinely used and in the assessment of renal functioning prior to contrast administration. IVC training varied in duration and number of supervised procedures required to fulfill competencies. CONCLUSION: IVC is used extensively in Irish RT departments. There are variations in IVC practice between departments and with international recommended guidelines.
RESUMO
BACKGROUND: The use of prophylactic cranial irradiation (PCI) to treat brain metastases (BM) in non-small cell lung cancer (NSCLC) is restricted due to the potential associated toxicity and lack of survival benefit. BM can have a negative impact on neurocognitive function (NF) and quality of life (QOL). The aim of this review was to assess the impact of PCI on disease-specific and NF and QOL outcomes. MATERIALS AND METHODS: An electronic database literature search was completed to identify relevant studies. RESULTS: Fourteen published articles were included. PCI significantly reduced the incidence of BM, but no significant survival advantage was found. NF decline was reported in one trial. No significant difference in QOL with PCI was reported. PCI was well tolerated by the majority of patients with NSCLC and associated with a relatively low toxicity. CONCLUSION: PCI reduces the incidence of BM without any significant survival advantage. PCI has the potential to be beneficial in practice for certain patients with locally advanced NSCLC, based on disease factors and patient preference.

OBJECTIVE:: The aim of this study is to investigate if a handheld ultrasound device (BladderScan® BVI 6100) can accurately measure bladder volumes in prostate radiotherapy (RT) patients. METHODS:: A comparison was made of contoured bladder volumes based on treatment planning CT (TPCT) and BladderScan® BVI 6100 ultrasound device in a large prostate RT population. Three bladder volume (BV) measurements were taken using the bladder volume instrument (BVI) device on prostate RT patients immediately prior to TPCT (n = 190). The CT delineation bladder volumes were also recorded. The mean of the three BVI readings (BVImean) and the maximum (BVImax) of the readings were considered for a comparative analysis. RESULTS:: There was a strong positive correlation between the BVI and CT delineated bladder volumes (BVImean r = 0.825; BVImax r = 0.830). The mean difference [± standard deviation (SD)] was an underestimation of BV for both BVImean and BVImax (44.8 ± 88.2 ml and 32.9 ± 87.5 ml, respectively). CONCLUSION:: This is the largest study to date (n = 190), assessing the accuracy of the BladderScan® BVI 6100 in the prostate RT population. The BVI 6100 provides an acceptable indication of BV for use in prostate RT patients for the purposes of monitoring BV.

INTRODUCTION: Radiotherapy education can be very different across Europe, despite the publication of the ESTRO core curricula in 2011. The purpose of the current study is to map the different RO European education systems, to report their perceived quality and to understand what could be improved to better teach RO. METHODS: An online survey consisting of 30 questions was sent to RO professionals under 40â¯years of age via email and social media. Clinicians, radiobiologists, physicists and radiation therapists (RTTs) were invited to answer questions regarding (1) demographics data, (2) duration, (3) organization, (4) content, (5) quality and potential improvements of national education programs. RESULTS: Four hundred and sixty three questionnaires were received from 34 European countries. All disciplines were represented: 45% clinicians (nâ¯=â¯210), 29% physicists (nâ¯=â¯135), 24% RTTs (nâ¯=â¯108) and 2% radiobiologists (nâ¯=â¯10). Male and female participants were well-balanced in each speciality, except for radiobiologists (80% males). Median age was 31.5â¯years old (range 21-40). A large range of the duration of the National RO education programs was observed: medianâ¯=â¯9â¯years (range: 3-15). In half of the surveyed countries the European Credit Transfer System (ECTS), that facilitates mobility for trainees, has been implemented. Participants declared only a minority of countries have implemented the ESTRO Core Curriculum (nâ¯=â¯5). A quarter of participants indicated that their national education program is insufficient. CONCLUSION: This is the first study to examine the different RO education systems in Europe. Large differences in organization and duration of national education programs have been found, along with perceived quality across Europe within each speciality. These results show the necessity of a discussion on how to move forward in this diversity of education programs and the potential contribution that the ESTRO may fulfil.
RESUMO
OBJECTIVE: to explore routine weighing in antenatal care and weight management in pregnancy with women who have been weighed during pregnancy. DESIGN: a qualitative study utilising semi-structured telephone interviews, and thematic analysis. SETTING: participants resided in Dublin, Ireland and had been weighed during pregnancy. PARTICIPANTS: individual telephone interviews conducted with ten postpartum women (nine months postpartum). FINDINGS: experiences of routine weighing were positive, and participants believed it should be part of standard antenatal care. Several benefits to routine weighing were cited, including providing reassurance and minimising postpartum weight retention. It was felt that there was a lack of information provided on gestational weight gain and healthy lifestyle in pregnancy, and that healthcare professionals are ideally placed to provide this advice. Increased information provision was seen as a method to improve healthy lifestyle behaviours in pregnancy. KEY CONCLUSIONS AND IMPLICATIONS FOR PRACTICE: these findings contribute to the current debate about the re-introduction of routine weighing throughout pregnancy (Allen-Walker et al., 2016). Women stated that they expected to be weighed during pregnancy and, contrary to previous claims, there was no evidence that routine weighing during antenatal care caused anxiety. From discussions it was clear that women desired more information on gestational weight gain and a healthy lifestyle, and felt that health professionals should provide this.
