- Context: De novo brain tumors developing after treatment of pituitary/sellar lesions have been reported, but it is unknown whether this is linked to any of the treatment modalities. Objective: To study the occurrence of malignant brain tumors and meningiomas in a large cohort of patients treated for pituitary/sellar lesions, with special emphasis on the role of radiotherapy (RT). Patients and Methods: Patients (n = 8917) who were hypopituitary due to pituitary adenomas, craniopharyngiomas, and other sellar tumors followed in KIMS (Pfizer International Metabolic Database) from 1994 to 2012 were included. Treatment consisted of surgery and/or medical therapy in 4927 patients, RT alone, or with surgery in 3236 patients; data were missing in 754. Incidence rate ratios (RRs) were analyzed through Poisson regression methods with internal comparisons. Results: During 53,786 patient-years, 17 cases of malignant brain tumors (13 exposed to RT) and 27 meningiomas (22 exposed to RT) were reported. RR for RT vs no RT was 3.34 [95% confidence interval (CI), 1.06 to 10.6] for malignant brain tumors, and 4.06 (95% CI, 1.51 to 10.9) for meningiomas. The risk of developing a malignant brain tumor increased by 2.4-fold (P = 0.005) and meningioma by 1.6-fold with every 10 years of younger age at RT (P = 0.05). Incidence rates were similar in patients treated with conventional RT compared with stereotactic RT. Conclusion: RT of pituitary tumors is associated with increased risk of developing malignant brain tumors and meningiomas, especially when given at younger ages. In balancing risks and benefits of RT, our findings emphasize that special consideration should be given to the age of the patient.

- Objective: Clinical observations over time of adults with growth hormone (GH) deficiency (GHD) have indicated a shift in patient characteristics at diagnosis. The objective of this study was to compare baseline characteristics of patients diagnosed with adult-onset GHD naive to GH replacement during t hree study periods (1994-1999 (P1), 2000-2004 (P2), and 2005-2012 (P3)) using the KIMS (Pfizer's International Metab olic) database. Methods: Data were retrieved for a total of 6069 patients with adult-on set GHD from six countries (Belgium, Germany, Netherlands, Spain, Sweden, and UK): P1 (n = 1705), P2 (n = 2397), and P3 (n = 1967). Results: The proportions of patients with pituitary/hypothalamic tumors and patients with multiple pituitary hormone deficiencies decreased per entry year period, while the proporti ons with hypertension and diabetes increased. The lag time from diagnosis of pituitary disease to start of GH treatme nt decreased by 2.9 years over the entry year periods. IGF-1 increased by 0.1 standard deviation score per entry year period. Maximum GH following various stimulation tests, BMI, and waist circumference increased. The use of radio therapy, glucocorticoid replacement doses, and the proportion of women >50 years on estrogen replacement therapy decreased. The effects of 1 year of GH replacement were similar over the entry year periods despite changes in the patients' baseline characteristics. An expected increase in fasting blood glucose was seen after 1 year of GH treatment. Conclusions: The degree of confirmed GHD became less pronounced and more pat ients with co-morbidities and diabetes were considered for GH replacement therapy, possibly r eflecting increased knowledge and confidence in GH therapy gained with time.

- Introduction: International guidelines recommend a bundle of care, including targeted temperature management (TTM), in post cardiac arrest survivors. Aside from a few small surveys in different European countries, adherence to the European Resuscitation Council (ERC) and European Society of Intensive Care Medicine (ESICM) recommendations are unknown. Methods: This international European telephone survey was conducted to provide an overview of current clinical practice of post cardiac arrest management with a main focus on TTM. We targeted large teaching and university hospitals within Europe as leading facilities and key opinion leaders in the field of post cardiac arrest care. Selected national principal investigators conducted the survey, which was based on a predefined questionnaire, between December 2014 and March 2015, before the publication of the ERC Guidelines 2015. Results: The return rate was 94% from 268 participating intensive care units (ICU). The majority had a predefined standard operating procedure (SOP) protocol for post cardiac arrest patients. Altogether, 68% of the ICUs provided TTM at a target temperature of 32-34. °C for 24. h, and 33% had changed the target temperature to 36. °C. The minority provided a written SOP for neurological prognostication, which was generally initiated 72. h after return of spontaneous circulation (ROSC). Electroencephalography and somatosensory evoked potentials were used by most ICUs for early prognostication. Treating more than fifty patients a year was significantly associated with providing written SOPs for TTM and prognostication (p. <. 0.01), as well as the use of a computer feedback device (p = 0.03) for TTM. Conclusion: This international European telephone survey revealed a high rate of implementation of TTM in post cardiac arrest patients in university and teaching hospitals. Most participants also provided a SOP, but only a minority had a SOP for neurological prognostication.

- Objective: To analyze the effectiveness and safety of growth hormone (GH) replacement treatment in adult patients with Langerhans cell histiocytosis (LCH) and GH deficiency (GHD) enrolled in KIMS (Pfizer International Metabolic Database). Patients and methods: Patients with LCH and GHD were studied at baseline and some of them after 1 year of GH treatment. The effectiveness of GH is presented as change after 1 year of treatment (mean, 95% CI). The LCH population was compared to two other groups of patients enrolled in KIMS, granulomatous and lymphocytic hypophysitis. Results: At baseline, 81 adults with LCH (27 with childhood onset, 56% females), mean age at GHD onset of 29 (15) years were studied. Diabetes insipidus was diagnosed in 86% of patients. Analysis of 1 year of GH treatment was possible in 37 patients. One-year cross-sectional values for the GH dose were 0.39 (S.D. ± 0.21) mg and -0.5 (-1.2 to 0.2) for insulin-like growth factor-1 S.D. Total cholesterol decreased 0.9 (-1.5 to -0.3 (mmol/L); P < 0.05); AGHDA-QoLscore (n = 20) was improved by 2.8 points (-5.6 to 0.0; P < 0.05), while mean BMI increased 0.6 ± 3 kg/m2 (95% CI: -0.2 to 1.4). All these effects did not differ from the two other groups after adjusting for age, gender, and baseline values. In 20 of 77 patients included in the safety analysis, 36 serious adverse events were reported during 435 patient-years (82.8/1000); no new safety signals were reported. Conclusion: After 1 year of GH treatment in patients with LCH, metabolic variables and quality of life improved, with no new safety signals.

- Context: In adults, craniopharyngioma (CP) of either childhood-onset (CO-CP) or adult-onset (AOCP) is associated with increased morbidity and mortality, but data on the relative risks (RRs) of contributing factors are lacking. Objective: To assess the RRs of factors contributing to morbidity and mortality in adults with CO-CP and AO-CP. Methods: Data on 1669 patients with CP from KIMS (Pfizer International Metabolic Database) were analyzed using univariate and multiple Poisson and Cox regression methods. Results:WhenCO-CP andAO-CP groupswere combined, history of stroke and hyperlipidemia increased cardiovascular risk, higher bodymass index (BMI) and radiotherapy increased cerebrovascular risk, and increased waist circumference increased the risk of developing diabetes mellitus (DM). Comparedwith patients with CO-CP, patients with AO-CP had a threefold higher risk of tumor recurrence, whereas being female and previous radiotherapy exposure conferred lower risks. Radiotherapy and older age with every 10 years from disease onset conferred a 2.3-To 3.5-fold risk for developing new intracranial tumors, whereas older age, greater and/or increasing BMI, history of stroke, and lower insulinlike growth factor I (IGF-I) standard deviation scoremeasured at last sampling before death were related to increased all-cause mortality. Compared with the general population, adults with CP had 9.3-, 8.1-, and 2.2-fold risks of developing DM, new intracranial tumors, and early death, respectively. Conclusion: Conventional factors that increase the risks of cardio-And cerebrovascular diseases and DM and risks for developing new intracranial tumors contributed to excess morbidity and mortality. In addition, lower serum IGF-I level measured from the last sample before death was inversely associated with mortality risk in patients with CP.
