Primary gliosarcoma: epidemiology, clinical presentation, management, and survival.

BACKGROUND: Gliosarcomas are malignant tumors of the central nervous system. As a variant of glioblastomas (GBM), they are treated in a similar fashion. However, there is growing evidence to suggest that they may be a separate entity. METHODS: Due to the rarity of primary gliosarcomas (PGS), here we publish data from a single center spanning over 14 years, comprising possibly one of the biggest case series in the literature to our knowledge. RESULTS: The mean age at presentation was 59 years with male preponderance (1.75:1). The most common presenting symptoms were balance and mobility issues (61%), followed by headaches (50%) and visual problems (39%). Tumours were most likely to involve the frontal and parietal lobes (27% and 21% respectively). Patients under 50 had a significant survival advantage (50% versus 32%). All patients had surgery, 79% had adjuvant radiotherapy, with a further 21% also receiving chemotherapy. Median survival from surgery of patients diagnosed with PGS was 6.6 months. Median and one-year survival were significantly better for patients who received radiotherapy (14 months; 46% one year survival) and improved further with combined radio- and chemotherapy (30 months; 77%, one year survival). CONCLUSIONS: For patients of good functional status, adjuvant chemo-radiotherapy is warranted and should be offered as it confers a much-improved overall survival.

Cancer screening: evidence and practice in Europe 2008.

We examine the theoretical basis of screening, followed by an evaluation of screening initiatives from a population health perspective and a discussion of the organisation of mass screening programmes. Evidence for the effectiveness of screening by primary site from both randomised trials and evaluation of service screening is summarised and the existing cancer screening programmes in the European Union are described. Sufficient evidence from several randomised trials to demonstrate mortality reduction exists for breast cancer and colorectal cancer screening. At least one trial has shown efficacy with a mortality end-point in screening for hepatocellular carcinoma and oral cancer. Randomised trials have demonstrated a lack of mortality effect in lung cancer screening based on chest X-ray and sputum cytology. Despite the lack of randomised trials, population screening for cervical cancer with cytological smears has been convincingly shown to reduce cervical cancer incidence and mortality.

Making progress against cancer in Europe in 2008.

Europe is facing a cancer epidemic, with rapidly increasing incidence rates. Population growth and ageing will further increase the annual number of new patients with cancer. Cancer is a huge and growing contributor to the burden of disease and premature death within the European Union (EU). One in four of all deaths in the EU is attributable to cancer, and in the age range 45-64 years, the figure is almost one in two deaths. The 27 EU Member States differ greatly in cancer incidence, mortality and survival. Yet at least one-third of the cancer burden is preventable and a further third can be detected early and treated effectively, even on the basis of existing knowledge. "Cancer", however, comprises an extremely complex group of diseases and achieving the full potential for prevention and treatment poses very significant challenges. Success in cancer control will depend on a co-ordinated approach that involves every aspect of policy and service delivery. The objective of this paper is to outline the basic requirements of an integrated strategy for cancer control, emphasising the co-ordination of the key elements of primary prevention, secondary prevention (screening), integrated care and advances in research, all at national and EU level. It is based on a detailed review of the status of cancer control in the EU today and summarises the policy recommendations arising from this review, undertaken under the auspices of the Slovenian Presidency of the European Union in 2008.

Magnitude and object-specific hazards of aspiration and ingestion injuries among children in Greece.

OBJECTIVE: To assess the public health impact of injuries due to foreign body aspirations and ingestions among children in terms of overall magnitude and estimation of object-specific incidence. METHODOLOGY: Two thousand two hundred and seven injuries due to aspiration and ingestion of foreign bodies were identified among 110 066 records of children (less than 15 years old) collected by the Hellenic Emergency Department Injury Surveillance System (EDISS) during the 5-year study period 1996-2000. Countrywide estimates of overall and object-specific injury incidence rates were computed using appropriate age and place of residence-sampling ratios. Simple cross-tabulations were performed along with a free text description analysis of injury events, whereas a composite score using (1) frequency of injury occurrence, (2) hospitalisation rate and (3) average length of hospitalisation was developed to measure the overall object-specific burden of injuries. RESULTS: Aspirations and ingestions of foreign bodies accounted for 2% of the total burden of accident and emergency department visits, corresponding to an annual incidence of approximately 2.3 accidents per 1000 children. Fish bones and nuts prevailed among the high (44%) proportion of aspirations and ingestions due to edible foreign bodies, while the main inedibles involved were small objects. Toddlers, boys and migrant children were over-represented among children sustaining injuries due to inedibles. As expected, the vast majority of food-related injuries occurred in the kitchen, in most instances under parental supervision. Injuries due to edibles were of minor severity and treatment was provided in the emergency departments, while those due to inedibles were responsible for injuries resulting in higher hospitalisation rates, albeit of relatively short duration. The composite impact score was highest for nuts and other food, nails, pins and sharp instruments. X-rays were performed in nearly all cases; upper gastrointestinal endoscopy was required in about 1 out of 10 instances and laryngoscopy or bronchoscopy in 1 out of 20, whereas the object was spontaneously removed in less than 3% of the cases. CONCLUSIONS: Depending on whether caused by edible or inedible objects, injuries due to foreign body aspirations and ingestions showed distinct epidemiological patterns. Composite scores taking into account measures of injury frequency and severity, seemed to reflect a country-specific spectrum of this type of injuries and provided useful information for the design of targeted public health oriented interventions.

Determinants of early life leptin levels and later life degenerative outcomes.

The early (intrauterine and neonatal) life environment plays an important role in programming the susceptibility in later life to chronic degenerative diseases, such as obesity, cardiovascular diseases, diabetes mellitus, cancer and osteoporosis. Among other hormones, leptin plays a major role in the regulation of the overall metabolism and has multiple neuroendocrine (adeno- and neuro-hypophysis axes and the hypothalamus-pituitary-adrenal axis) and immune functions. The hormone exerts its actions beginning in the early life time period, regulating the intrauterine and early extrauterine life growth and development, as well as the adaptation to extrauterine life, neonatal thermogenesis and response to stress. Recent findings also support a role of leptin in the process of fetal bone remodeling and brain development. Therefore, it is of interest to explore the physiology of leptin in early life, as well as those factors that may perturb the balance of the hormone with pathological consequences in terms of confining an increased risk for disease in later life. This review aims to summarize reported findings concerning the role of leptin in early life, as well as the association of fetal, maternal and placental factors with leptin levels, while attempting to speculate mechanisms through which these factors may influence the risk for developing chronic diseases in later life.

A maternity hospital-based infant car-restraint loan scheme: public health and economic evaluation of an intervention for the reduction of road traffic injuries.

AIMS: The results of an infant car-restraint loan scheme and evaluate its cost-effectiveness are presented. METHODS: The intervention programme was initiated in 1996. Car-restraints, donated by manufacturers, were lent for a six-month period to eligible prospective parents for a modest fee. Specially trained health visitors performed in-person interviews with the participating parents. The data were collected and recorded on a pre-coded questionnaire. Cross-tabulations and multiple logistic regression were performed to analyse the data. Subsequent purchase of a next-stage car restraint, suitable for older children (up to four years of age) was considered as a proxy measure of the success of the programme. This information, along with the detailed operational and financial data collected during the implementation phase of the programme, was used to develop a model to assess the cost-effectiveness of a countrywide intervention. RESULTS: During a two-year period 188 families participated in a survey. On return of the infant car restraint, 92% of the participants reported proper use of the device and 82% had already purchased the second-stage car restraint. Parental age, gender, or educational status was not predictive of positive parental road safety practices for the newly born, whereas history of parental seat-belt use--as a proxy of personal road safety behaviour--was positively correlated with the likelihood of purchasing a second-stage car-restraint device. The cost-effectiveness ratio varies between 418.00 euro and 3,225.00 euro per life-year saved, depending on whether the modest administrative fee is considered. CONCLUSIONS: On the basis of plausible assumptions, a loan programme of infant car-restraints was shown to be particularly cost effective.

Serum adiponectin concentrations in relation to maternal and perinatal characteristics in newborns.

OBJECTIVE: To assess serum adiponectin levels of neonates in relation to ponderal index and birth length with and without adjustment for potential confounding factors including maternal factors and perinatal characteristics. DESIGN: A cross-sectional study. METHODS: Three hundred and three newborns (Caucasian, singleton, full term, with a birth weight of > or =2500 g, and apparently healthy) were included in the study. Blood samples were collected from the newborns no later than the fifth day of life for measurements of adiponectin and major IGF system components (IGF-I, IGF-II, IGF binding protein-3 (IGFBP-3)). The data were analyzed using simple and multiple regression analyses. RESULTS: Adiponectin is substantially higher in neonates than in adults, with no evidence of the gender dimorphism observed among adults. We found an inverse association between neonatal adiponectin levels and newborn ponderal index and a positive association with newborn length by univariate analysis. We also found a statistically significant inverse association of adiponectin with jaundice/bilirubin, and a marginally significant positive association of this hormone with IGFBP-3 but no significant association with any maternal factors. In multivariate analysis, the inverse association between serum adiponectin and ponderal index does not remain significant after adjustment for potential confounding factors. In contrast, neonatal adiponectin levels correlate inversely significantly and independently with liver maturity and IGF-II and tend to remain positively associated with IGFBP-3 and increased birth length. CONCLUSIONS: An inverse association of adiponectin with ponderal index by univariate analysis is not independent from confounding factors. In contrast, the positive association between serum adiponectin and birth length may reflect either a direct effect of adiponectin or an adiponectin-mediated increase in the sensitivity of tissues to insulin and components of the IGF system, and needs to be explored further.

Incidence and risk factors of fall injuries among infants: a study in Greece.

OBJECTIVE: To assess the incidence of fall injuries among infants in Greece, overall and by type of nursery equipment. DESIGN: Review of data from a large injury database. SETTING: The Emergency Department Injury Surveillance System in Greece. PATIENTS: A total of 2672 injured infants. INTERVENTIONS: Specially trained health visitors performed in-person interviews with the children's guardians, using a precoded questionnaire. The results of an independent survey of 777 mothers of noninjured children younger than 2 years attending the same emergency departments were used to allow quantification of the role of specific nursery equipment in the causation of infant fall injuries. MAIN OUTCOME MEASURES: Annual rate of injury by falling in infants, overall and by cause. RESULTS: About 4400 infant fall injuries occur annually in Greece, corresponding to an annual incidence rate of 44 injuries per 1000 infants. The incidence of falls increases with increasing infant age. A high percentage of severe injuries was detected, most of them concussions (14.3%) and fractures (9.4%). Approximately 10% of infants with fall-related injuries required hospitalization. More than 36% of fall injuries involved nursery equipment. Infant walker use was associated with a higher incidence of falls (about 9 per 1000 infant-years), and these falls occasionally involved stairs and caused serious injuries. Infant bouncers, strollers, and changing tables were all associated with a similar incidence of falls (about 4 per 1000 infant-years). CONCLUSIONS: Falls are a common cause of serious infant injuries, and nursery equipment is frequently involved in the injury-causing event.

Adiponectin and breast cancer risk.

Adiponectin, an adipocyte-secreted hormone, is closely and inversely associated with insulin resistance and was recently found to be inversely and independently associated with endometrial cancer. Because insulin resistance in the setting of obesity has also been associated with the development of breast cancer, we have hypothesized that decreased adiponectin levels might underlie the association between breast cancer and obesity/insulin resistance. We evaluated the association of adiponectin with the occurrence of breast cancer in a case-control study comprising 174 women with newly diagnosed, histologically confirmed breast cancer and 167 controls. We found an inverse, fairly strong, and statistically significant association of serum adiponectin with breast cancer (odds ratio, 0.84; 95% confidence interval, 0.71-0.99). Importantly, despite a fairly robust inverse association of adiponectin with breast cancer risk among postmenopausal women (odds ratio, 0.82; 95% confidence interval, 0.67-1.00), no such significant association between adiponectin and breast cancer was found among premenopausal women. The observed associations were independent of possible effects of major components of the IGF system, leptin, body mass index, sociodemographic variables, and known risk factors for breast cancer. Future studies are needed to prove causality and provide further insights into both the mechanisms underlying the actions of this hormone and its potential role in breast cancer.

Endometrial cancer and the IGF system: a case-control study in Greece.

OBJECTIVES: Insulin-like growth factor I (IGF-I) and other components of the IGF system have been implicated in the etiology of several human malignancies. We have undertaken a case-control study among Greek women to explore the relation of major components of the IGF system (IGF-I, IGF-II and IGF-binding protein 3, IGFBP-3) with endometrial cancer risk. METHODS: During a 1-year period (1999), 84 incident cases of histologically confirmed endometrial cancer were compared with 84 control women admitted to the same clinical department for small gynecological operations, mainly pelvic prolapse. Data were modeled through multiple logistic regression. RESULTS: Endometrial cancer was positively associated with IGF-II and inversely with IGF-I. Both associations were statistically significant and they appear symmetrical around the null value. IGFBP-3 is positively associated with endometrial cancer risk, but this association does not reach statistical significance. CONCLUSIONS: This study adds to the gradually developing consensus that components of the IGF system play a central role in human carcinogenesis. It is possible that IGF-II, rather than IGF-I, is closely linked to the etiology of endometrial cancer, the form of cancer most strongly associated with obesity.
