Anthropometric and reproductive factors and risk of esophageal and gastric cancer by subtype and subsite: Results from the European Prospective Investigation into Cancer and Nutrition (EPIC) cohort

Obesity has been associated with upper gastrointestinal cancers; however, there are limited prospective data on associations by subtype/subsite. Obesity can impact hormonal factors, which have been hypothesized to play a role in these cancers. We investigated anthropometric and reproductive factors in relation to esophageal and gastric cancer by subtype and subsite for 476,160 participants from the European Prospective Investigation into Cancer and Nutrition cohort. Multivariable hazard ratios (HRs) and 95% confidence intervals (CIs) were estimated using Cox models. During a mean follow-up of 14 years, 220 esophageal adenocarcinomas (EA), 195 esophageal squamous cell carcinomas, 243 gastric cardia (GC) and 373 gastric noncardia (GNC) cancers were diagnosed. Body mass index (BMI) was associated with EA in men (BMI ≥30 vs. 18.5–25 kg/m²: HR = 1.94, 95% CI: 1.25–3.03) and women (HR = 2.66, 95% CI: 1.15–6.19); however, adjustment for waist-to-hip ratio (WHR) attenuated these associations. After mutual adjustment for BMI and HC, respectively, WHR and waist circumference (WC) were associated with EA in men (HR = 3.47, 95% CI: 1.99–6.06 for WHR >0.96 vs. <0.91; HR = 2.67, 95% CI: 1.52–4.72 for WC >98 vs. <90 cm) and women (HR = 4.40, 95% CI: 1.35–14.33 for WHR >0.82 vs. <0.76; HR = 5.67, 95% CI: 1.76–18.26 for WC >84 vs. <74 cm). WHR was also positively associated with GC in women, and WC was positively associated with GC in men. Inverse associations were observed between parity and EA (HR = 0.38, 95% CI: 0.14–0.99; >2 vs. 0) and age at first pregnancy and GNC (HR = 0.54, 95% CI: 0.32–0.91; >26 vs. <22 years); whereas bilateral ovariectomy was positively associated with GNC (HR = 1.87, 95% CI: 1.04–3.36). These findings support a role for hormonal pathways in upper gastrointestinal cancers.

Patterns in metabolite profile are associated with risk of more aggressive prostate cancer: A prospective study of 3,057 matched case–control sets from EPIC

Metabolomics may reveal novel insights into the etiology of prostate cancer, for which few risk factors are established. We investigated the association between patterns in baseline plasma metabolite profile and subsequent prostate cancer risk, using data from 3,057 matched case–control sets from the European Prospective Investigation into Cancer and Nutrition (EPIC). We measured 119 metabolite concentrations in plasma samples, collected on average 9.4 years before diagnosis, by mass spectrometry (AbsoluteIDQ p180 Kit, Biocrates Life Sciences AG). Metabolite patterns were identified using treelet transform, a statistical method for identification of groups of correlated metabolites. Associations of metabolite patterns with prostate cancer risk (OR_1SD) were estimated by conditional logistic regression. Supplementary analyses were conducted for metabolite patterns derived using principal component analysis and for individual metabolites. Men with metabolite profiles characterized by higher concentrations of either phosphatidylcholines or hydroxysphingomyelins (OR_1SD = 0.77, 95% confidence interval 0.66–0.89), acylcarnitines C18:1 and C18:2, glutamate, ornithine and taurine (OR_1SD = 0.72, 0.57–0.90), or lysophosphatidylcholines (OR_1SD = 0.81, 0.69–0.95) had lower risk of advanced stage prostate cancer at diagnosis, with no evidence of heterogeneity by follow-up time. Similar associations were observed for the two former patterns with aggressive disease risk (the more aggressive subset of advanced stage), while the latter pattern was inversely related to risk of prostate cancer death (OR_1SD = 0.77, 0.61–0.96). No associations were observed for prostate cancer overall or less aggressive tumor subtypes. In conclusion, metabolite patterns may be related to lower risk of more aggressive prostate tumors and prostate cancer death, and might be relevant to etiology of advanced stage prostate cancer.     

Infectious scleritis: Report of four cases

While systemic autoimmune diseases are the main possibilities in the differential diagnosis of scleritis, other less common etiologies such as infections must also be considered. The authors report four cases of infectious scleritis to review predisposing factors, clinical characteristics, methods of diagnostic approach, and response to therapy. Two patients had primary scleritis and two patients had secondary scleritis following extension of primary corneal infection (corneoscleritis). Diagnoses included three local infections (one each withStaphylococcus. Acanthamoeba, and herpes simplex) and one systemic infection (Lyme disease). Stains, cultures, or immunologic studies from scleral, conjunctival, and/or corneal tissues, and serologic tests were used to make the diagnosis. Medical therapy, including antimicrobial agents, was instituted in all patients, and surgical procedures were additionally required in two patients (scleral grafting in one and two penetrating keratoplasties in another); the patient who required two penetrating keratoplasties had corneoscleritis and underwent eventual enucleation. Infectious agents should be considered in the differential diagnosis of scleritis.     

Multidimensional approach to the differences between muscular and articular temporomandibular patients: coping, distress, and pain characteristics.

OBJECTIVE: This study analyzes the differences in psychological variables and symptomatology between temporomandibular disorder diagnosis subgroups. STUDY DESIGN: The sample included 114 temporomandibular disorder patients that were evaluated in coping, distress, and temporomandibular characteristics. Diagnostic muscular (n = 58) and articular (n = 56) subgroups were compared in these variables through a MANCOVA. RESULTS: Muscular patients show a higher level of general distress, specifically in the anxiety and somatization subscales and a more active coping style, with a tendency of a minor use of humor and a higher number of parafunctional habits, specifically, biting nails, hangnails, and lips. CONCLUSION: We discuss the differences found in order to design the targets of the psychological intervention of temporomandibular patients.     

State of infectious disease notification (I.D.N.'s) in Navarra. 1996

The System of Infectious Disease Notification (I.D.N.) encompasses the notification of 41 infectious transmissible diseases to which are added epidemic outbreaks of any etiology or cause. In Navarra, the I.D.N.'s are reported to the Section of Vigilance and Epidemiological Control of the Public Health Institute. A sharp increase of alimentary toxic-infections is observed due to two community outbreaks produced by Salmonella enteritidis that affected 410 persons. The incidence of pulmonary tuberculosis, 15.37 cases per 100,000 inhabitants has remained at the same levels as previous years and with lower rates than those published in neighbouring Autonomous Communities such as La Rioja and the Autonomous Community of the Basque Country. In the group of Exanthematic Diseases, an outbreak of German measles is noteworthy that affected males between the ages of 16 and 20. During the year 1996 there were 17 cases of Meningococcal Disease that meant a rate of 3.27 per 100,000 inhabitants, the second lowest rate in the last 25 years after the rate of 2.29 of 1994. With respect to the causative serogroup, serogroup C was isolated on 7 occasions, serogroup B on four occasions and on 6 it could not be grouped. Hydatidosis through reports of I.D.N.'s and active search in the hospitals remained steady, with 26 cases, remaining within the regular values of recent years. An important decline with respect to recent years was observed in cases of hepatitis A, hepatitis B and brucellosis.     

Evaluation of the Program for the Prevention and Control of Tuberculosis during the period January 1993 - June 1996

In 1992 a Technical Commission was formed in Navarra with the participation of different specialists who drew up the Program of Vigilance and Control of Tuberculosis. We present the results of the evaluation of this program for the period from January 1993 to June 1996. In the 3.5 years of the study, 419 cases of tuberculosis were found, 317 belonging to respiratory forms and 102 to extra-respiratory forms. The annual rate of incidence of total tuberculosis, 22.8 cases per 100,000 inhabitants observed in Navarra, is the lowest of those registered at the level of the Autonomous Communities according to the TIR study of the SEPAR (acronym for Spanish Society of Pneumology and Thoracic Surgery) in 1996, and the second lowest, after Castilla-La Mancha, according to the multicentric study of the National Centre of Epidemiology. In Navarra the highest rates of incidence are produced in those over 65 years of age, following the pattern observed in the more developed countries. 13.9% of the patients with respiratory tuberculosis showed co-infection by HIV, and besides more than 90% of these were users of intravenous drugs. The percentage of immigrants, prisoners and the destitute observed in the Navarra series is lower than that found in areas such as Madrid, Barcelona or Zaragoza. 91% of the cases of respiratory tuberculosis showed bacteriological confirmation and 98% of the cases were diagnosed and treated in specialised care. Outstanding were the high follow-up of the cases until discharge and the high percentage of cures achieved, some 85.4%.     

Continuous care in the cancer patient: palliative care in the 21<Superscript>st</Superscript> century

Continuous care for the cancer patient is an open concept that is not only applicable only to the terminal stage. Such a simplification could generate inequities of therapy and discrimination. Historically, oncology services have been structured as networks dispensing chemotherapy and radiotherapy rather than services dedicated to the integrated care of the cancer patient. This situation has changed in a continuous and progressive manner over the past few years, as reflected in the latest Spanish Libro Blanco de Oncología. We are still far from reaching the optimum level of integrated care, possibly because we have not, as yet, achieved services that are structured and appropriate for the care-needs of the patient and, perhaps, to the lack of the necessary personnel. We must always make sure that cancer patients receive the best possible treatment, irrespective of whet-her the disease is in relapse. Oncologists must not “give up”, indicating that, in addition to using the most effective anticancer treatments available, they should deploy their best knowledge and experience to control the symptoms of cancer while providing psycho-social help to the patient and family. This is best conducted with a communication that is adjusted to the changing needs of the patient over the longterm clinical process, and should be provided by a multidisciplinary team, according to the needs of the patient and the family. Within a program of integrated care, it is possible to coordinate the existing care structures without creating parallel health networks so as to cover the needs of the greatest number of cancer patients in advanced stage of the disease.     

Functional asymmetries in early learning during right,left, and bimanual performance in right‐handed subjects

Purpose:

To elucidate differences in activity and connectivity during early learning due to the performing hand.

Materials and Methods:

Twenty right‐handed subjects were recruited. The neural correlates of explicit visuospatial learning executed with the right, the left hand, and bimanually were investigated using functional magnetic resonance imaging. Connectivity analyses were carried out using the psychophysiological interactions model, considering right and left anterior putamen as index regions.

Results:

A common neural network was found for the three tasks during learning. Main activity increases were located in posterior cingulate cortex, supplementary motor area, parietal cortex, anterior putamen, and cerebellum (IV–V), whereas activity decrements were observed in prefrontal regions. However, the left hand task showed a greater recruitment of left hippocampal areas when compared with the other tasks. In addition, enhanced connectivity between the right anterior putamen and motor cortical and cerebellar regions was found for the left hand when compared with the right hand task.

Conclusion:

An additional recruitment of brain regions and increased striato‐cortical and striato‐cerebellar functional connections is needed when early learning is performed with the nondominant hand. In addition, access to brain resources during learning may be directed by the dominant hand in the bimanual task. J. Magn. Reson. Imaging 2013;37:619–631. © 2012 Wiley Periodicals, Inc.
