Object Previous small studies disagree about which clinical risk factors influence ependymoma incidence. The authors analyzed a large, population-based cancer registry to examine the relationship of incidence to patient age, sex, race, and tumor location, and to determine incidence trends over the past 3 decades. Methods Data were obtained from the Surveillance, Epidemiology, and End Results (SEER-9) study, which was conducted from 1973 to 2003. Histological codes were used to define ependymomas. Age-adjusted incidence rates were compared by confidence intervals in the SEER*Stat 6.2 program. Multiplicative Poisson regression and Joinpoint analysis were used to determine annual percentage change and to look for sharp changes in incidence, respectively. Results From the SEER database, 1402 patients were identified. The incidence rate per 100,000 person-years was significantly higher in male than in female patients (males 0.227 ± 0.029, females 0.166 ± 0.03). For children, the age at diagnosis differed significantly by tumor location, with the mean age for patients with infratentorial tumors calculated as 5 ± 0.4 years; for supratentorial tumors it was 7.77 ± 0.6 years, and for spinal lesions it was 12.16 ± 0.8 years. (Values are expressed as the mean ± standard error [SE].) Adults showed no difference in the mean age of incidence by location, although most tumors in this age group were spinal. Between 1973 and 2003, the incidence increased significantly among adults but not among children, and there were no sharp changes at any single year, both before and after age adjustment. Conclusions Males have a higher incidence of ependymoma than do females. A biological explanation remains elusive. Ependymoma occurs within the CNS at distinct locations at different ages, consistent with hypotheses postulating distinct populations of radial glial stem cells within the CNS. Ependymoma incidence appears to have increased over the past 3 decades, but only in adults.

The Impact

With increasing shortage of fresh water globally, more countries are consuming desalinated seawater (DSW). In Israel >50% of drinking water is now derived from DSW. Desalination removes magnesium, and hypomagnesaemia has been associated with increased cardiac morbidity and mortality. Presently the impact of consuming DSW on body magnesium status has not been established. We quantified changes in serum magnesium in a large population based study (n = 66,764), before and after desalination in regions consuming DSW and in regions where DSW has not been used. In the communities that switched to DSW in 2013, the mean serum magnesium was 2.065 ± 0.19 mg/dl before desalination and fell to 2.057 ± 0.19 mg/dl thereafter (p < 0.0001). In these communities 1.62% of subjects exhibited serum magnesium concentrations ≤1.6 mg/dl between 2010 and 2013. This proportion increased by 24% between 2010–2013 and 2015–2016 to 2.01% (p = 0.0019). In contrast, no such changes were recorded in the communities that did not consume DSW. Due to the emerging evidence of increased cardiac morbidity and mortality associated with hypomagnesaemia, it is vital to consider re-introduction of magnesium to DSW.

Introduction:Many population-based studies identify surgical complications using hospital discharge abstract databases (DAD). With DAD, however, complications occurring after the discharge date cannot be followed up. This study used physician claims data to identify the complications of partial nephrectomy, and to compare the rates of complications of open, laparoscopic, and robot-assisted nephrectomies.Methods:Physician claims, DAD, and ambulatory care data from April 2003 to March 2016 were provided by Alberta Health. DAD and ambulatory care data were used to extract information on patients with kidney cancer who underwent partial nephrectomy. All physician claims within 30 days before and after surgery for the cohort were extracted. The numbers of the same International Classification of Diseases, Ninth Revision (ICD-9), codes before and after surgery were compared. If a number increased after surgery, this diagnosis was initially identified as a complication. All diagnoses with neoplasms were excluded. The incidence rates of complications for the three surgery groups were calculated. Chi-squared tests were conducted for the following nephrectomy comparisons: laparoscopic versus open; robot-assisted versus open; and robot-assisted versus laparoscopic.Results:A total of 1,890 kidney cancer patients had partial nephrectomies. Among them, 1,080, 411, and 399 had open, laparoscopic, and robot-assisted nephrectomies, respectively. One patient who had two different nephrectomies on the same day was excluded from analysis. The robot-assisted group had lower rates of digestive complications (ICD-9: 537–578, 787, 789, 998.6) and infections (ICD-9: 004–041, 998.5) than the open group, and higher rates of genitourinary complications (ICD-9: 584–599, 788, 997.5) than the laparoscopy group. The robot-assisted group had lower rates than the open group for most of the complication categories, but the differences were not statistically significant.Conclusions:Robot-assisted surgery appears to be superior to open surgery, but no better than laparoscopic surgery, in terms of minimizing the risk of complications following partial nephrectomy.

BackgroundTobacco 21 (T21) laws, which raise the minimum legal age of sale of tobacco products to 21, have been proposed and implemented in states and cities across the USA. However, limited data are available on the effect of T21 laws on youth tobacco purchasing behaviours and access to tobacco products.MethodsParticipants in a population-based prospective cohort in southern California completed questionnaires before (n=1609, age=18–19 y) and after (n=1502, age=19–20 y) T21 was implemented in California (June 2016). We examined the prevalence of past 30-day cigarette and e-cigarette use, and among past 30-day users, purchase location of tobacco products before (pre-) versus after (post-) T21. We also examined whether, post-T21, participants were refused purchase of tobacco products due to their age, and the perceived relative ease of purchasing cigarettes and e-cigarettes (vs pre-T21).ResultsNegligible changes in cigarette and e-cigarette use were observed pre-T21 versus post-T21. At both time points, the majority of past 30-day users purchased cigarettes from gas stations and e-cigarettes from vape shops. Post-T21, the proportion of participants who reported purchasing cigarettes at gas stations decreased. Post-T21, most past 30-day cigarette or e-cigarette users were not refused purchase of cigarettes (65.4%) or e-cigarettes (82.0%) in the past 30 days, despite being under 21; half of the participants felt it was harder to purchase cigarettes (54.3%) and e-cigarettes (43.6%) post-T21.ConclusionPost-T21, few participants were refused purchase of any tobacco product, despite the illegality of such sales. Better enforcement of T21 is needed to improve the efficacy of T21 legislation.

Background and Purpose: A stroke incidence study in ­Örebro, situated in Southern Sweden, that was carried out in 1999 showed high incidence rates. Since then, in many Western countries, declining incidence rates have been observed. The main purpose of this study is to examine whether there have been any changes in stroke incidence in the city of ­Örebro between 1999 and 2017. Secondary purposes are to show trends in stroke severity, length of stay and case fatality (CF). Methods: The criterion of an “ideal” stroke incidence study was used in both the 1999 and the present investigation. These criteria include uniform diagnostics, case ascertainment including strokes managed outside the hospital, and the use of several overlapping sources, prospective design, well-defined denominator, and a large population. Results: The overall stroke incidence rate of first ever stroke (adjusted to the 2013 European population) dropped from 346/100,000 (95% CI 314–380) to 168/100,000 (95% CI 148–190). Stroke severity declined from a median of 6 to 4 points on the National Institute of Health Stroke scale. CF within 28 days also declined from 19 to 16% (n.s.). Median length-of-stay in hospital was 16 days in 1999, and 10 days in 2017. Twenty-one per cent of all kinds of stroke were recurrent (not included in the above results). Conclusions: During the years between 1999 and 2017, there have been reductions in stroke incidence, severity and mortality. The explanation is most likely to be found in the prevalence of risk factors and how they are treated. The use of antihypertensives and statins has increased, corresponding to lower levels of blood pressure and cholesterol in the population. The use of anticoagulants in patients with atrial fibrillation has increased. Cigarette smoking has decreased. These are encouraging results that show that preventive medication and public health measures work in practice.

Abstract Objective To estimate the overall risk and the temporal trend of venous thromboembolism (VTE), deep vein thrombosis (DVT), and pulmonary embolism (PE) before and after gout diagnosis in an incident gout cohort compared with the general population. Methods We conducted a matched cohort study using a province-wide population-based administrative health database in Canada. We calculated incidence rates (IRs) and multivariable adjusted hazard ratios (HRs) for the risk of VTE, DVT and PE before and after gout diagnosis. Results Among 130 708 incident individuals with gout (64% male, mean age 59 years), 2071 developed VTE, 1377 developed DVT and 1012 developed PE. IRs per 1000 person-years for gout were 2.63, 1.74 and 1.28 compared with 2.03, 1.28 and 1.06 for non-gout, respectively. The fully adjusted HRs (95% CI) for VTE, DVT and PE were 1.22 (1.13, 1.32), 1.28 (1.17, 1.41) and 1.16 (1.05, 1.29). For the pre-gout period, the fully adjusted HRs (95% CI) were 1.51 (1.38, 1.64), 1.55 (1.40, 1.72) and 1.47 (1.31, 1.66) for VTE, DVT and PE. During the third, second and first years preceding gout, the fully adjusted HRs for VTE were 1.44, 1.56 and 1.62. During the first, second, third, fourth and fifth years after gout, the fully adjusted HRs were 1.63, 1.29, 1.33, 1.28 and 1.22. Similar trends were also seen for DVT and PE. Conclusion Increased risks of VTE, DVT and PE were found both before and after gout diagnosis. The risk increased gradually before gout, peaking in the year prior to diagnosis, and then progressively declined. Gout-associated inflammation may contribute to venous thrombosis risk.

Objective: The role of resistin in insulin sensitivity and obesity is controversial. Some authors suggest that increased serum resistin levels are associated with obesity, visceral fat, insulin resistance, type 2 diabetes and inflammation, while others failed to observe such correlations. The aim of the present study was to investigate the relationship of plasma resistin levels with markers of the metabolic syndrome and atherosclerosis in a large population-based study. Design and patients: Plasma resistin levels were determined in 1090 subjects free of any medication selected from the PLIC study (designed to verify the presence of atherosclerotic lesions and progression intima-media thickness (IMT) in the common carotid artery in the general population) and related to the presence of obesity, metabolic syndrome, metabolic abnormalities, cardiovascular risk, and progression of IMT. Results: Plasma resistin levels were highly positively correlated with triglycerides, waist circumference, waist/hip ratio, systolic blood pressure, and ApoAI/ApoB ratio, while they were inversely correlated with high density lipoprotein and ApoAI levels. This finding was gender specific (mainly in women). Plasma resistin levels were significantly higher in women with the metabolic syndrome compared with controls (4.90 (0.24) ng/ml vs 3.90 (0.11) ng/ml; P<0.01), while no difference was observed in obese subjects. Finally, plasma resistin levels were significantlycorrelated with cardiovascular risk calculated according to the Framingham algorithm (P<0.01). Conclusion: Plasma resistin levels are increased in presence of the metabolic syndrome and are associated with increased cardiovascular risk.

4123 Background: The study examines the prognostic significance of tumor location exclusively in rectosigmoid and rectal cancers. Although tumor location has traditionally been regarded as a prognostic determinant, data in support of this claim are lacking. We set out to determine this using data from a large population-based California Cancer Registry (CCR). Methods: A retrospective analysis of surgically treated cancer cases involving the rectum and rectosigmoid from 1994–2006 with a follow-up until January 2008 in CCR was conducted. Sub-site tumor location of the cancers involving the rectum was either defined as rectosigmoid or mid/distal rectum. Site-specific survival analyses were conducted by Kaplan-Meier method and hazard ratio calculated using Cox proportional hazard ratios (HR). Results: A total of 33,418 rectal cancer cases were identified, including 12,407 (37.1%) rectosigmoid cancers and 21,011 (62.9%) mid/distal rectum cancers. No significant differences by tumor location were noticed for age, gender, stage, histological type, grade or socioeconomic status. Fewer rectosigmoid cancers received radiation (81.9% vs. 62.3% p=<0.0001)) compared to mid/distal rectum cancers. After adjustment for treatment and relevant clinical factors, an improved rate of CRC-specific survival was noticed in non-metastatic rectosigmoid cancers when compared to cancers involving the mid/distal rectum. A significant decrease in mortality was observed in Stage-I [HR- 0.74(0.63–0.86)], Stage-II [HR-0.76(0.69–0.85)] and Stage-III [HR- 0.90 (0.83–0.98)] rectosigmoid cancers when compared to mid/distal rectum cancers. Number of lymph nodes examined (>12 vs. <12) was an independent prognostic factor for survival in Stage-II patients [HR-0.74 (0.63–0.87)]. Conclusions: Among locoregional cases, rectosigmoid cancers were found to have an improved CRC-specific survival compared to mid/distal rectum cancers, which was independent of other relevant clinical factors.

e17031 Background: Incidence of vulvar cancer in Germany is increasing. Gynecological oncologists reported to observe increasing numbers of women presenting with small tumors. The aim of the presented study is to validate this observation on a population level and to extend available incidence data. Methods: Data from the population-based Saarland Cancer Registry (CR) were used and included 1,136 female patients diagnosed with invasive vulvar cancer (ICD-10 code: C51) between 1974 and 2013. Multiple imputation methodology was used to overcome loss of precision and potential bias. Incidence trends were investigated with regard to patient and tumor characteristics. Results: During the study period, the age standardized rate of incidence increased from 1.6 to 7.9 cases per 100,000 women per year (+390%). Since 1989, the incidence of squamous cell carcinoma increased from 1.7 to 7.1 (+320%), whereas no increase was observed in other morphologic types. Simultaneously, the incidence of small vulvar tumors <= 2 cm (T1) increased from 0.8 in 1989-93 to 6.6 in 2009-13 (the proportion of T1 tumors increased from 34% to 79%, respectively). Patients aged >= 75 years suffered from more advanced disease at the time of diagnosis. Conclusions: The detailed analyses revealed that the observed increase in vulvar cancer in the past 15 years mainly resulted from newly incident squamous cell carcinomas. Furthermore, the analyses showed an almost exclusive increase of T1 tumors. An increase in vulvar cancer incidence as shown for Germany could not be observed for any other European country.

The diaphragma sellae (DS) is a fold of dura that forms a partial roof over the pituitary gland. The foramen of the diaphragma sellae (FDS) is thereby a pathway for suprasellar extension of pituitary tumors. The purpose of this study was to describe the anatomical dimensions of the DS and FDS and to understand the relationship of FDS with the overlying optic chiasma. The study was conducted in 100 autopsy cases. Measurements were taken using vernier calipers. Photographs, taken before and after removal of optic pathway, were superimposed using image processing software. The results showed that the mean A-P dimension of DS was 1.17 ± 0.48 cm; the lateral dimension of DS was 1.58 ± 0.60 cm. The mean A-P dimension of FDS was 0.66 ± 0.42 cm; the lateral dimension of FDS was 0.82 cm ± 0.54 cm. The shapes of FDS were irregular (40%), transversely oval (29%), circular (13%), sagittally oval (11%), or trapezoid with posterior dimension more than the anterior one (6%) or anterior dimension more than the posterior one (1%). The margins of FDS were either well defined (31%) or ill defined (69%). The positional relation of FDS to optic chiasma was also found out.

Abstract There have been no prior large population-based studies focusing on cutaneous lymphomas (CL) in the United States. Using the Surveillance, Epidemiology and End Results (SEER) program data, we analyzed age-adjusted CL incidence rates (IRs) and survival rates by sex and race/ethnicity. There were 3884 CLs diagnosed during 2001-2005. Cutaneous T-cell lymphomas (CTCLs) accounted for 71% (age-adjusted incidence rate [IR] = 7.7/1 000 000 person-years), whereas cutaneous B-cell lymphomas(CBCLs) accounted for 29% (IR = 3.1/1 000 000 person-years). Males had a statistically significant higher IR of CL than females (14.0 vs 8.2/1 000 000 person-years, respectively; male-female IR ratio [M/F IRR] = 1.72; P < .001). CL IRs were highest among blacks and non-Hispanic whites (both 11.5/1 000 000 person-years), followed by Hispanic whites (7.9) and Asian/Pacific Islanders (7.1). The CTCL IR was highest among blacks (10.0/1 000 000 person-years), whereas the CBCL IR was highest among non-Hispanic whites (3.5). Over the past 25 years, the CL IR increased from 5.0/1 000 000 person-years during 1980-1982 to 14.3 during 2001-2003. During 2004-2005, the CL IR was 12.7. This recent apparent change could be incomplete case ascertainment or potential leveling off of IRs. CLs rates vary markedly by race and sex, supporting the notion that they represent distinct disease entities.
