    Abstract Background: Acute pancreatitis (AP) is a frequent cause of hospitalization with long-term health consequences, including type 3c diabetes mellitus (DM). The incidence and risk factors for new-onset morbidities after AP need to be clarified to inform a personalized medicine approach.
    Methods: Using a longitudinal electronic healthcare record-linkage analysis, all patients admitted to hospital in Scotland with a first episode of AP between 1 April 2009 and 31 March 2012 and followed for a minimum of 5 years after their index AP admission were identified. All new-onset morbidity with specific focus on type 3c DM were analysed and, using time-split multiple regression.
    Results: A total of 2047 patients were included. AP requiring critical care was followed by 2 years of heightened risk (HR 5.24) of developing type 3c DM, increased risk of new-onset cardiac disease (HR 1.61), and renal disease (HR 2.96). The additional risk conferred by critical care AP had a negative interaction with time, whereas additional risk associated with male sex and a non-gallstone aetiology was long lasting.
    Conclusion: Based on these findings, a personalized approach to include type 3c DM screening for a minimum of 2 years for individuals who required critical care when hospitalized with AP is recommended.

    Abstract Objective: To measure the increasing incidence of primary hyperparathyroidism (PHPT) in Scotland, to determine the relationship between PHPT and deprivation, and to investigate the relationship between parathyroidectomy (PTX) and social deprivation.
    Methods: We retrospectively identified a cohort of patients diagnosed with PHPT between 1986 and 2013 from the Scottish Morbidity Records (SMR01) database. The diagnosis of PHPT was made in accordance with the International Classification of Diseases code.
    Results: Between the years 1986 and 2013, 4002 patients were diagnosed with PHPT. There was a significant increase in the incidence of PHPT in this period (p < 0.0001), an association between the incidence of PHPT and deprivation (p < 0.0001) plus an association between a lower rate of PTX and deprivation (p < 0.001).
    Conclusion: The increase in incidence of PHPT may be due to a combination of increased awareness of PHPT, easier diagnosis, and an ageing population. The lower rate of PTX in relation to deprivation may reflect comorbidities, age, and uncertainty about the long-term benefits of PTX in asymptomatic patients.

    Abstract Background: It has been suggested that the risk of oesophageal adenocarcinoma might be increased in patients with a history of eating disorders due to acidic damage to oesophageal mucosa caused by self-induced vomiting practiced as a method of weight control. Eating disorders have also been associated with risk factors for squamous cell carcinoma of the oesophagus, including alcohol use disorders, as well as smoking and nutritional deficiencies, which have been associated with both main sub-types of oesophageal cancer. There have been several case reports of oesophageal cancer (both main sub-types) arising in patients with a history of eating disorders.
    Methods: We used linked records of hospitalisation, cancer registration and mortality in Scotland spanning 1981-2012 to investigate the risk of oesophageal cancer among patients with a prior history of hospitalisation with eating disorder. The cohort was restricted to patients aged ≥10 years and <60 years at the date of first admission with eating disorder. Disregarding the first year of follow-up, we calculated indirectly standardised incidence ratios using the general population as the reference group to generate expected numbers of cases (based on age-, sex-, socio-economic deprivation category-, and calendar period-specific rates of disease).
    Results: After exclusions, the cohort consisted of 3617 individuals contributing 52,455 person-years at risk. The median duration of follow-up was 13.9 years. Seven oesophageal cancers were identified, as compared with 1.14 expected, yielding a standardised incidence ratio of 6.1 (95% confidence interval: 2.5-12.6). All were squamous cell carcinomas arising in females with a prior history of anorexia nervosa.
    Conclusions: Patients hospitalised previously with eating disorders are at increased risk of developing oesophageal cancer. Confounding by established risk factors (alcohol, smoking, and nutritional deficiency) seems a more likely explanation than acidic damage through self-induced vomiting because none of the incident cases of oesophageal cancer were adenocarcinomas, and because the study cohort had higher than background rates of hospitalisation with alcohol-related conditions and chronic obstructive pulmonary disease.

    Abstract Introduction: Severe acute pancreatitis (AP) requiring critical care admission (ccAP) impacts negatively on long-term survival.
    Objective: To document organ-specific new morbidity and identify risk factors associated with premature mortality after an episode of ccAP.
    Design: Cohort study.
    Setting: Electronic healthcare registries in Scotland.
    Participants: The ccAP cohort included 1471 patients admitted to critical care with AP between 1 January 2008 and 31 December 2010 followed up until 31 December 2014. The population cohort included 3450 individuals from the general population of Scotland frequency-matched for age, sex and social deprivation.
    Methods: Record linkage of routinely collected electronic health data with population matching.
    Primary and secondary outcome measures: Patient demographics, comorbidity (Charlson Comorbidity Index), acute physiology, organ support and other critical care data were linked to records of mortality (death certificate data) and new-onset morbidity. Kaplan-Meier and Cox regression analyses were used to identify risk factors associated with mortality.
    Results: 310 patients with AP died during the index admission. Outcomes were not ascertained for five patients, and the deprivation quintile was not known for six patients. 340 of 1150 patients in the resulting postdischarge ccAP cohort died during the follow-up period. Greater comorbidity measured by the Charlson score, prior to ccAP, negatively influenced survival in the hospital and after discharge. The odds of developing new-onset diabetes mellitus after ccAP compared with the general population were 10.70 (95% CI 5.74 to 19.94). A new diagnosis of myocardial infarction, stroke, heart failure, liver disease, peptic ulcer, renal failure, cancer, peripheral vascular disease and lung disease was more frequent in the ccAP cohort than in the general population.
    Conclusions: The persistent deleterious impact of severe AP on long-term outcome and survival is multifactorial in origin, influenced by pre-existing patient characteristics and acute episode features. Further mechanistic and epidemiological investigation is warranted.

    Abstract Study question: What is the impact of cancer in females aged ≤39 years on subsequent chance of pregnancy?
    Summary answer: Cancer survivors achieved fewer pregnancies across all cancer types, and the chance of achieving a first pregnancy was also lower.
    What is known already: The diagnosis and treatment of cancer in young females may be associated with reduced fertility but the true pregnancy deficit in a population is unknown.
    Study design, size, duration: We performed a retrospective cohort study relating first incident cancer diagnosed between 1981 and 2012 to subsequent pregnancy in all female patients in Scotland aged 39 years or less at cancer diagnosis (n = 23 201). Pregnancies were included up to end of 2014. Females from the exposed group not pregnant before cancer diagnosis (n = 10 271) were compared with general population controls matched for age, deprivation quintile and year of diagnosis.
    Participants/materials, setting, methods: Scottish Cancer Registry records were linked to hospital discharge records to calculate standardized incidence ratios (SIR) for pregnancy, standardized for age and year of diagnosis. Linkage to death records was also performed. We also selected women from the exposed group who had not been pregnant prior to their cancer diagnosis who were compared with a matched control group from the general population. Additional analyses were performed for breast cancer, Hodgkin lymphoma, leukaemia, cervical cancer and brain/CNS cancers.
    Main results and the role of chance: Cancer survivors achieved fewer pregnancies: SIR 0.62 (95% CI: 0.60, 0.63). Reduced SIR was observed for all cancer types. The chance of achieving a first pregnancy was also lower, adjusted hazard ratio = 0.57 (95% CI: 0.53, 0.61) for women >5 years after diagnosis, with marked reductions in women with breast, cervical and brain/CNS tumours, and leukaemia. The effect was reduced with more recent treatment period overall and in cervical cancer, breast cancer and Hodgkin lymphoma, but was unchanged for leukaemia or brain/CNS cancers. The proportion of pregnancies that ended in termination was lower after a cancer diagnosis, and the proportion ending in live birth was higher (78.7 vs 75.6%, CI of difference: 1.1, 5.0).
    Limitations, reasons for caution: Details of treatments received were not available, so the impact of specific treatment regimens on fertility could not be assessed. Limited duration of follow-up was available for women diagnosed in the most recent time period.
    Wider implications of the findings: This analysis provides population-based quantification by cancer type of the effect of cancer and its treatment on subsequent pregnancy across the reproductive age range, and how this has changed in recent decades. The demonstration of a reduced chance of pregnancy across all cancer types and the changing impact in some but not other common cancers highlights the need for appropriate fertility counselling of all females of reproductive age at diagnosis.
    Study funding/competing interest(s): This study was funded by NHS Lothian Cancer and Leukaemia Endowments Fund. Part of this work was undertaken in the MRC Centre for Reproductive Health which is funded by the MRC Centre grant MR/N022556/1.

    Abstract Background: The proportion of births via cesarean section (CS) varies worldwide and in many countries exceeds WHO-recommended rates. Long-term health outcomes for children born by CS are poorly understood, but limited data suggest that CS is associated with increased infection-related hospitalisation. We investigated the relationship between mode of birth and childhood infection-related hospitalisation in high-income countries with varying CS rates.
    Methods and findings: We conducted a multicountry population-based cohort study of all recorded singleton live births from January 1, 1996 to December 31, 2015 using record-linked birth and hospitalisation data from Denmark, Scotland, England, and Australia (New South Wales and Western Australia). Birth years within the date range varied by site, but data were available from at least 2001 to 2010 for each site. Mode of birth was categorised as vaginal or CS (emergency/elective). Infection-related hospitalisations (overall and by clinical type) occurring after the birth-related discharge date were identified in children until 5 years of age by primary/secondary International Classification of Diseases, 10th Revision (ICD-10) diagnosis codes. Analysis used Cox regression models, adjusting for maternal factors, birth parameters, and socioeconomic status, with results pooled using meta-analysis. In total, 7,174,787 live recorded births were included. Of these, 1,681,966 (23%, range by jurisdiction 17%-29%) were by CS, of which 727,755 (43%, range 38%-57%) were elective. A total of 1,502,537 offspring (21%) had at least 1 infection-related hospitalisation. Compared to vaginally born children, risk of infection was greater among CS-born children (hazard ratio (HR) from random effects model, HR 1.10, 95% confidence interval (CI) 1.09-1.12, p < 0.001). The risk was higher following both elective (HR 1.13, 95% CI 1.12-1.13, p < 0.001) and emergency CS (HR 1.09, 95% CI 1.06-1.12, p < 0.001). Increased risks persisted to 5 years and were highest for respiratory, gastrointestinal, and viral infections. Findings were comparable in prespecified subanalyses of children born to mothers at low obstetric risk and unchanged in sensitivity analyses. Limitations include site-specific and longitudinal variations in clinical practice and in the definition and availability of some data. Data on postnatal factors were not available.
    Conclusions: In this study, we observed a consistent association between birth by CS and infection-related hospitalisation in early childhood. Notwithstanding the limitations of observational data, the associations may reflect differences in early microbial exposure by mode of birth, which should be investigated by mechanistic studies. If our findings are confirmed, they could inform efforts to reduce elective CS rates that are not clinically indicated.

    Abstract Background/objectives: Advances in cancer management have resulted in improved survival rates, particularly in children and young adults. However, treatment may adversely affect reproductive outcomes among female cancer survivors. The objective of this study was to investigate their risk of adverse perinatal outcomes compared to the general population.
    Design/methods: We performed a population-based analysis, including all female cancer survivors diagnosed before the age of 40 years between 1981 and 2012. Pregnancy and perinatal complications were identified through linkage of the Scottish Cancer Registry with hospital discharge records based on the Community Health Index (CHI) database. We compared 1,629 female cancer survivors with a first ever singleton pregnancy after diagnosis, with controls matched on age, deprivation quintile, and year of cancer diagnosis selected from the general population (n = 8,899). Relative risks and 95%-confidence intervals of perinatal risks were calculated using log-binomial regression.
    Results: Survivors were more likely to give birth before 37 weeks of gestation (relative risk (RR]) 1.32, 95%-CI 1.10-1.59), but did not show an increased risk of low birth weight (<2.5kg: RR 1.15, 95%-CI 0.94-1.39), and were less likely to give birth to offspring small for gestational age (RR 0.81, 95%-CI 0.68-0.98). Operative delivery and postpartum haemorrhage were more common but approached rates in controls with more recent diagnosis. The risk of congenital abnormalities was not increased (RR 1.01, 95%-CI 0.85-1.20).
    Conclusion: Cancer survivors have an increased risk of premature delivery and postpartum haemorrhage, but their offspring are not at increased risk for low birth weight or congenital abnormalities. In recent decades there has been a normalisation of delivery method in cancer survivors, nevertheless careful management remains appropriate particularly for those diagnosed in childhood.
