Psychological well-being of people with epilepsy in Norway

The subjective well-being of people with epilepsy has been studied extensively, but only sparingly in Norway. In 2005, members of the Norwegian Epilepsy Association responded to a short version of the Hopkins Symptom Check List ("psychological distress") and to a version of the Self-Anchoring Striving Scale, also termed the Cantril Ladder ("life satisfaction"). In this article, the relationships between responses to the two questionnaires (the two outcome variables) and seizure frequency, medication side effects, comorbidity, and surgery, as well as demographic variables such as age, sex, marital status, occupational status, education, and place of residence, are addressed. The analyses demonstrate clear effects of seizure frequency (P<0.001) and medication side effects (P<0.001) on both outcome variables. People with no comorbidity (no additional diagnoses) reported less psychological distress (P<0.001) and greater satisfaction with life (P<0.05) than those who reported additional diagnoses. The factor having the strongest impact on the psychological well-being of these people was medication side effects.     

Hantavirus reservoir Oligoryzomys longicaudatus spatial distribution sensitivity to climate change scenarios in Argentine Patagonia

Background  

Oligoryzomys longicaudatus (colilargo) is the rodent responsible for hantavirus pulmonary syndrome (HPS) in Argentine Patagonia. In past decades (1967–1998), trends of precipitation reduction and surface air temperature increase have been observed in western Patagonia. We explore how the potential distribution of the hantavirus reservoir would change under different climate change scenarios based on the observed trends.     

Immunocytochemical expression of E-cadherin on fine-needle aspirates from breast carcinomas correlate with the cell dissociation pattern seen on smears.

Altered E-cadherin expression has been suggested to be of prognostic significance in breast cancers and to correlate with tumor subtype and grade. A dysfunctional, intercellular adhesion system may be responsible for the tumor cell dissociation pattern seen on fine-needle aspirate cytology (FNAC). The aim of our study was to determine E-cadherin expression on direct FNAC smears from breast carcinomas and compare the results with the dyscohesion grade of the tumor cells and the cytological grading. The material consisted of FNAs from 56 breast carcinomas. The degree of cellular cohesion was estimated semiquantitatively. Full expression of E-cadherin was defined as a complete and strong membrane staining of virtually all tumor cells. All nonductal as well as 85% of the invasive ductal carcinomas revealed reduced expression or negativity for E-cadherin. In all, 25% of carcinomas with dyscohesion Grade 1 (mainly in groups) revealed full expression of E-cadherin, in contrast to 12.5% of tumors with dyscohesion Grade 3 (mainly dispersed cells). Nuclear positivity was seen in 21% of the tumors (12 cases) and seven of these were G3 ductal carcinomas. In conclusion, E-cadherin expression correlated with the cell dissociation pattern seen on direct smears from FNAC of breast carcinomas, but is only one of several markers that modulate this pattern. High-grade carcinomas rarely revealed full expression and had a high incidence of aberrant nuclear localization of E-cadherin.     

Elevation of cerebrospinal fluid soluble CD27 levels in patients with meningeal localization of lymphoid malignancies [published erratum appears in Blood 1996 Oct 1;88(7):2818]

Diagnosis of meningeal localization of lymphoid malignancies by means of cytologic examination of the cerebrospinal fluid (CSF) can be difficult. Thus far no reliable CSF tumor markers have been identified. CD27 is a transmembrane disulfide-linked 55-kD homodimer present on most peripheral blood T cells and on a subset of B cells. CD27 is also expressed on human malignant B cells and high levels of soluble CD27 can be present in the serum of patients with B-cell malignancies. The aim of this study is to determine prospectively the diagnostic value of CSF sCD27 as a tumor marker in patients with meningeal localization of lymphoid malignancies. CSF sCD27 levels were determined by sandwich enzyme-linked immunosorbent assay. The optimal cut-off value using receiver operator characteristics curves was found to be 10 U/mL. sCD27 levels were normal in all 50 control patients (lumbar disc protrusion) and in 39 of 40 samples obtained from patients with either solid tumors or acute myeloid leukemia. Of 104 CSF samples from 70 children with acute lymphoblastic leukemia (ALL) or non-Hodgkin's lymphoma (NHL) undergoing routine central nervous system (CNS) staging, sCD27 was false positive and false negative in only one sample each. In 70 samples from 45 patients suspected of meningeal localization of ALL or NHL, the sCD27 test had an excellent sensitivity (100%) and specificity (82%). In 7 patients with positive CSF studied longitudinally, sCD27 levels correlated very well with remission and relapse. sCD27 levels were not nonspecifically increased by the administration of cytostatic drugs. Finally, sCD27 was also elevated in the 4 patients studied with primary central nervous system lymphoma (PCNSL). CSF sCD27 is a promising tumor marker in patients with either meningeal localization of lymphoid malignancies or PCNSL, and can be useful in the differential diagnosis of CNS involvement by either lymphoid malignancies or solid tumors.     

Inequalities in full immunization coverage: trends in low- and middle-income countries

ObjectiveTo investigate disparities in full immunization coverage across and within 86 low- and middle-income countries.MethodsIn May 2015, using data from the most recent Demographic and Health Surveys and Multiple Indicator Cluster Surveys, we investigated inequalities in full immunization coverage – i.e. one dose of bacille Calmette-Guérin vaccine, one dose of measles vaccine, three doses of vaccine against diphtheria, pertussis and tetanus and three doses of polio vaccine – in 86 low- or middle-income countries. We then investigated temporal trends in the level and inequality of such coverage in eight of the countries.FindingsIn each of the World Health Organization’s regions, it appeared that about 56–69% of eligible children in the low- and middle-income countries had received full immunization. However, within each region, the mean recorded level of such coverage varied greatly. In the African Region, for example, it varied from 11.4% in Chad to 90.3% in Rwanda. We detected pro-rich inequality in such coverage in 45 of the 83 countries for which the relevant data were available and pro-urban inequality in 35 of the 86 study countries. Among the countries in which we investigated coverage trends, Madagascar and Mozambique appeared to have made the greatest progress in improving levels of full immunization coverage over the last two decades, particularly among the poorest quintiles of their populations.ConclusionMost low- and middle-income countries are affected by pro-rich and pro-urban inequalities in full immunization coverage that are not apparent when only national mean values of such coverage are reported.
