Abstract
Quantifying parenchymal tissue changes in the lungs is imperative in furthering the study of radiation induced lung damage (RILD). Registering lung images from different time-points is a key step of this process. Traditional intensity-based registration approaches fail this task due to the considerable anatomical changes that occur between timepoints. This work proposes a novel method to successfully register longitudinal pre- and post-radiotherapy (RT) lung computed tomography (CT) scans that exhibit large changes due to RILD, by extracting consistent anatomical features from CT (lung boundaries, main airways, vessels) and using these features to optimise the registrations. Pre-RT and 12 month post-RT CT pairs from fifteen lung cancer patients were used for this study, all with varying degrees of RILD, ranging from mild parenchymal change to extensive consolidation and collapse. For each CT, signed distance transforms from segmentations of the lungs and main airways were generated, and the Frangi vesselness map was calculated. These were concatenated into multi-channel images and diffeomorphic multichannel registration was performed for each image pair using NiftyReg. Traditional intensity-based registrations were also performed for comparison purposes. For the evaluation, the pre- and post-registration landmark distance was calculated for all patients, using an average of 44 manually identified landmark pairs per patient. The mean (standard deviation) distance for all datasets decreased from 15.95 (8.09) mm pre-registration to 4.56 (5.70) mm post-registration, compared to 7.90 (8.97) mm for the intensity-based registrations. Qualitative improvements in image alignment were observed for all patient datasets. For four representative subjects, registrations were performed for three additional follow-up timepoints up to 48 months post-RT and similar accuracy was achieved. We have demonstrated that our novel multichannel registration method can successfully align longitudinal scans from RILD patients in the presence of large anatomical changes such as consolidation and atelectasis, outperforming the traditional registration approach both quantitatively and through thorough visual inspection.

Abstract
Lung cancer is a leading cause of death worldwide. Radiation therapy (RT) is one method to treat this disease. A common side effect of RT for lung cancer is radiation-induced lung damage (RILD) which leads to loss of lung function. RILD often compounds pre-existing smoking-related regional lung function impairment. It is difficult to predict patient outcomes due to large variability in individual response to RT. In this study, the capability of image-based modelling of regional ventilation in lung cancer patients to predict lung function post-RT was investigated. Twenty-five patient-based models were created using CT images to define the airway geometry, size and location of tumour, and distribution of emphysema. Simulated ventilation within the 20 Gy isodose volume showed a statistically significant negative correlation with the change in forced expiratory volume in 1 s 12-months post-RT (p = 0.001, R = - 0.61). Patients with higher simulated ventilation within the 20 Gy isodose volume had a greater loss in lung function post-RT and vice versa. This relationship was only evident with the combined impact of tumour and emphysema, with the location of the emphysema relative to the dose-volume being important. Our results suggest that model-based ventilation measures can be used in the prediction of patient lung function post-RT.

Abstract
BACKGROUND Uterine rupture is associated with severely adverse maternal and neonatal outcomes. The association between uterine rupture and long-term cardiovascular hospitalization of the offspring has not been investigated yet. METHODS In a population-based cohort study, the incidence of cardiovascular related hospitalizations was compared between singletons born to mothers with and without uterine rupture in the current pregnancy. Cardiovascular hospitalization up to the age of 18 years was assessed according to a predefined set of ICD-9 codes associated with offspring hospitalization. Multiple gestations, perinatal deaths, lacking prenatal care, and children with congenital malformations or chromosomal abnormalities were excluded from the study. A Kaplan-Meier survival curve was used to assess cumulative incidence of cardiovascular hospitalization of the offspring. A Cox proportional hazards model was performed to control for confounders. RESULTS During the study period, 238,622 newborns met the inclusion criteria, of which 0.053% (n = 127) were born to mothers with uterine rupture in the current pregnancy. Children born to mothers with uterine rupture had significantly higher rates of cardiovascular related hospitalization (Kaplan-Meier's survival curve log-rank test, p=.005). CONCLUSION Being born following uterine rupture is an independent risk factor for long-term pediatric cardiovascular hospitalization. Highlights Uterine rupture is a risk factor for long-term pediatric cardiovascular related hospitalization. Rising rate of CS potentially associate to long-term offspring cardiovascular disease. Cardiovascular surveillance is needed for newborns delivered after uterine rupture.

Abstract
OBJECTIVE Animal studies indicate a possible intrauterine immunological imprinting in pregnancies complicated by hypothyroidism. We aimed to evaluate whether exposure to maternal hypothyroidism during pregnancy increases the risk of long-term infectious morbidity of the offspring. STUDY DESIGN A retrospective cohort study compared the long-term risk of hospitalization associated with infectious morbidity in children exposed and unexposed in utero to maternal hypothyroidism. Outcome measures included infectious diagnoses obtained during any hospitalization of the offspring (up to the age of 18 years). RESULTS The study included 224,950 deliveries. Of them, 1.1% (n = 2,481) were diagnosed with maternal hypothyroidism. Children exposed to maternal hypothyroidism had a significantly higher rate of hospitalizations related to infectious morbidity (13.2 vs. 11.2% for control; odds ratio: 1.2; 95% confidence interval: 1.08-1.36; p = 0.002). Specifically, incidences of ear, nose, and throat; respiratory; and ophthalmic infections were significantly higher among the exposed group. The Kaplan-Meier curve indicated that children exposed to maternal hypothyroidism had higher cumulative rates of long-term infectious morbidity. In the Cox proportional hazards model, maternal hypothyroidism remained independently associated with an increased risk of infectious morbidity in the offspring while adjusting for confounders. CONCLUSION Maternal hypothyroidism during pregnancy is associated with significant pediatric infectious morbidity of the offspring.

Prediction of a positive circumferential resection margin at surgery following neoadjuvant chemotherapy for adenocarcinoma of the oesophagus. BJS Open 2019; 3:767-776.

Abstract
Background A positive circumferential resection margin (CRM) has been associated with higher rates of locoregional recurrence and worse survival in oesophageal cancer. The aim of this study was to establish if clinicopathological and radiological variables might predict CRM positivity in patients who received neoadjuvant chemotherapy before surgery for oesophageal adenocarcinoma. Methods Multivariable analysis of clinicopathological and CT imaging characteristics considered potentially predictive of CRM was performed at initial staging and following neoadjuvant chemotherapy. Prediction models were constructed. The area under the curve (AUC) with 95% confidence intervals (c.i.) from 1000 bootstrapping was assessed. Results A total of 223 patients were included in the study. Poor differentiation (odds ratio (OR) 2·84, 95 per cent c.i. 1·39 to 6·01) and advanced clinical tumour status (T3-4) (OR 2·93, 1·03 to 9·48) were independently associated with an increased CRM risk at diagnosis. CT-assessed lack of response (stable or progressive disease) following chemotherapy independently corresponded with an increased risk of CRM positivity (OR 3·38, 1·43 to 8·50). Additional CT evidence of local invasion and higher CT tumour volume (14 cm3) improved the performance of a prediction model, including all the above parameters, with an AUC (c-index) of 0·76 (0·67 to 0·83). Variables associated with significantly higher rates of locoregional recurrence were pN status (P = 0·020), lymphovascular invasion (P = 0·007) and poor response to chemotherapy (Mandard score 4-5) (P = 0·006). CRM positivity was associated with a higher locoregional recurrence rate, but this was not statistically significant (P = 0·092). Conclusion The presence of advanced cT status, poor tumour differentiation, and CT-assessed lack of response to chemotherapy, higher tumour volume and local invasion can be used to identify patients at risk of a positive CRM following neoadjuvant chemotherapy.

Abstract
Background Previous analyses of the oesophageal circumferential resection margin (CRM) have focused on the prognostic validity of two different definitions of a positive CRM, that of the College of American Pathologists (tumour at margin) and that of the Royal College of Pathologists (tumour within 1 mm). This study aimed to analyse the validity of these definitions and explore the risk of recurrence and survival with incremental tumour distances from the CRM. Methods This cohort study included patients who underwent resection for adenocarcinoma of the oesophagus between 2000 and 2014. Kaplan-Meier and Cox regression analyses were performed to determine the hazard ratio (HR) with 95 per cent confidence intervals for recurrence and mortality in CRM increments: tumour at the cut margin, extending to within 0·1-0·9, 1·0-1·9, 2·0-4·9 mm, and 5·0 mm or more from the margin. Results A total of 444 patients were included in the study. Kaplan-Meier and unadjusted analyses showed a significant incremental improvement in overall survival (P < 0·001) and recurrence (P for trend < 0·001) rates with increasing distance from the CRM. Tumour distance of 2·0 mm or more remained a significant predictor of survival on multivariable analysis (HR for risk of death 0·66, 95 per cent c.i. 0·44 to 1·00). Multivariable analysis of overall survival demonstrated a significant difference between a positive and negative CRM with the Royal College of Pathologists' definition (HR 1·37, 1·01 to 1·85), but not with the College of American Pathologists' definition (HR 1·22, 0·90 to 1·65). Conclusion This study demonstrated an incremental improvement in survival and recurrence rates with increasing tumour distance from the CRM.

Abstract
Six UK studies investigating stereotactic ablative radiotherapy (SABR) are currently open. Many of these involve the treatment of oligometastatic disease at different locations in the body. Members of all the trial management groups collaborated to generate a consensus document on appropriate organ at risk dose constraints. Values from existing but older reviews were updated using data from current studies. It is hoped that this unified approach will facilitate standardised implementation of SABR across the UK and will allow meaningful toxicity comparisons between SABR studies and internationally.

Abstract
OBJECTIVE The concept of neonatal programming has begun to emerge as an important component of adult health. Scarce data exist regarding perinatal risk factors for long-term gastrointestinal (GI) morbidity of the offspring. We aimed to evaluate the association between birthweight (BW) at term and long-term pediatric GI morbidity. STUDY DESIGN A population-based cohort analysis was performed, comparing the risk of long-term GI morbidity (up to the age of 18 years) in children delivered at term according to their BW. The study included all term deliveries occurring between 1991 and 2014 at a single regional tertiary medical center. Multiple gestations and fetuses with congenital malformations were excluded. BW was subdivided into: small for gestational age (small for gestational age (SGA) - BW ≤ 5th centile), appropriate for gestational age (AGA -5th centile < BW < 95th centile), and large for gestational age (LGA - BW ≥95th centile). Hospitalizations up to the age of 18 years involving GI morbidity were evaluated, using a predefined set of ICD-9 codes, as recorded in the hospital files. A Kaplan-Meier survival curve was used to compare cumulative GI morbidity incidence. A Cox proportional hazards model was constructed to control for confounders. RESULTS During the study period, 225,600 term singleton deliveries met the inclusion criteria. Of them, 4.6% (n = 10,415) were SGA and 4.3% (n = 9796) were LGA. During the 18-years follow-up period, 11,791 (5.2%) children were hospitalized with GI morbidity. Hospitalizations were significantly more common in the SGA group, as compared with the AGA and LGA groups (6.6 versus 5.2 versus 4.5%, respectively, p < .001) Specifically, inflammatory bowel disease, celiac, hernia, hepatitis, and cholecystitis, were more common in the SGA group. The Kaplan-Meier survival curve demonstrated a significantly higher cumulative incidence of gastrointestinal morbidity in the SGA group (log rank p < .001). In the Cox proportional hazards model, controlled for relevant clinical confounders, SGA BW was found to be an independent risk factor for long-term GI morbidity (adjusted HR = 1.23, 95%CI 1.14-1.33, p < .001). CONCLUSIONS SGA offspring are at an increased and independent risk for long-term pediatric GI morbidity.

Abstract
It has been established as a common knowledge that ambient air pollution (AAP) has an adverse effect on human health. The pathophysiological mechanism of this impact is likely to be related to the oxidative stress. In the current study we estimate the association between AAP and cell proliferation (CP) of umbilical cord blood cells, representing maternal organism most proximal to the fetal body. Blood samples were tested for proliferation in 292 enrolled Arab-Bedouin women at delivery (July 2012-March 2013). The estimates of AAP were defined by a hybrid satellite based model predicting both PM2.5 (particles<2.5µm in diameter) and PM10 (particles<10µm in diameter) as well as monitoring stations for gaseous air pollutants. Risk estimates of pollution exposure were adjusted to medical history, household risk factors and meteorological factors on the day of delivery or one week prior. Ambient ozone (O3) levels on 1, 2, 3and 4 days prior to delivery were associated with lower CP (Prevalence ratio (PR)=0.92, 0.92, 0.93, 0.93, respectively). Increase in inter-quartile range (IOR) of PM2.5 one day before delivery was associated with 9% increase in CP levels (PR=1.09). The positive direction in association was changed to negative association with CP for PM2.5 levels measured at more distant time periods (PR=0.90 and 0.93 for lags 5 and 6 days, respectively). Investigation of PM10 levels indicated a similar pattern (PR=1.05 for pollution values recorded one day before delivery and 0.93 and 0.95 for lags of 5 and 6 days, respectively). Carbon monoxide (CO) levels were associated with lower CP on the day of delivery and 1day prior (PR=0.92 and PR=0.94). To conclude, the levels of cell proliferation of umbilical cord blood cells appear to be associated with the AAP. More studies are needed to support our findings.

Abstract
Nitrogen Dioxide (NO2) is a product of fuel combustion originating mainly from industry and transportation. Studies suggest an association between NO2 and congenital malformations (CM). We investigated an independent effect of NO2 on CM by adjusting to individual factors and household environment in 1024 Bedouin-Arab pregnant women in southern Israel. This population is characterised by high rates of CMs, frequent consanguineous marriages, paternal smoking, temporary housing and usage of open fire for heat cooking. Information on household risk factors was collected during an interview. Ambient measurements of 24-h average NO2 and meteorological conditions were obtained from 13 local monitors. Median value of daily NO2 measured in the area was 6.78ppb. CM was diagnosed in 8.0% (82) of offspring. Maternal NO2 exposure during the 1st trimester >8.6ppb was significantly associated with minor CM (RR=2.68, p=0.029). Major CM were independently associated with maternal juvenile diabetes (RR=9.97, p-value=0.002) and heating by open fire (RR=2.00, p-value=0.049), but not NO2 exposure. We found that NO2 emissions had an independent impact only on minor malformations, whereas major malformations depended mostly on the household environment. Antepartum deaths were associated by maternal morbidity.

Abstract
Androgen administration can cause prostate cancer progression, and androgen deprivation therapy is a commonly used therapeutic modality in the treatment of prostate cancer. In trying to answer the posed clinical question, this article reviews the risks and benefits of testosterone replacement therapy in this setting and the published data from clinical series. Recommendations are made based on the available evidence.
