Area of residence and alcohol-related mortality risk: a five-year follow-up study

Aims

Relationship between socioeconomic deprivation or urban/rural residence and visual acuity before cataract surgery in Northern Scotland

Purpose: To evaluate the influence of socioeconomic factors on visual acuity before cataract surgery. ?Methods: The medical case notes of 240 consecutive patients listed for cataract surgery from January 1, 2010, at Grampian University Hospital, Aberdeen, were reviewed retrospectively. Patients with ocular comorbidity were excluded. Demographics, postal codes, and visual acuity were recorded. Scottish Index of Multiple Deprivation was used to determine the deprivation rank. Home location was classified as urban or rural. The effect of these parameters on preoperative visual acuity was investigated using chi-square tests or Fisher exact test as appropriate. ?Results: A total of 184 patients (mean 75 years) were included. A total of 127 (69%) patients had visual acuity of 6/12 or better. An association was found between affluence and preoperative visual acuity of 6/12 or better (?2trend = 4.97, p = 0.03), with a significant rising trend across quintile of deprivation. There was no evidence to suggest association between geographical region and preoperative visual acuity (p = 0.63). ?Conclusion: Affluence was associated with good visual acuity (6/12 or better) before cataract surgery. There was no difference in preoperative visual acuity between rural and urban populations.

Dissolved uranium, radium and radon evolution in the Continental Intercalaire aquifer, Algeria and Tunisia

Natural, dissolved 238U-series radionuclides (U, 226Ra, 222Rn) and activity ratios (A.R.s: 234U/238U; 228Ra/226Ra) in Continental Intercalaire (CI) groundwaters and limited samples from the overlying Complexe Terminal (CT) aquifers of Algeria and Tunisia are discussed alongside core measurements for U/Th (and K) in the contexts of radiological water quality, geochemical controls in the aquifer, and water residence times. A redox barrier is characterised downgradient in the Algerian CI for which a trend of increasing 234U/238U A.R.s with decreasing U-contents due to recoil-dominated 234U solution under reducing conditions allows residence time modelling ∼500 ka for the highest enhanced A.R. = 3.17. Geochemical modelling therefore identifies waters towards the centre of the Grand Erg Oriental basin as palaeowaters in line with reported 14C and 36Cl ages. A similar 234U/238U trend is evidenced in a few of the Tunisian CI waters. The paleoage status of these waters is affirmed by both noble gas recharge temperatures and simple modelling of dissolved, radiogenic 4He-contents both for sampled Algerian and Tunisian CI and CT waters. For the regions studied these waters therefore should be regarded as “fossil” waters and treated effectively as a non-renewable resource.

A methodology to estimate the residence time of estuaries

The residence time has long been used as a classification parameter for estuaries and other semi- enclosed water bodies. It aims to quantify the time water remains inside the estuary, being used as an indicator both for pollution assessment and for ecological processes. Estuaries with a short residence time will export nutrients from upstream sources more rapidly then estuaries with longer residence time. On the other hand the residence time determines if micro-algae can stay long enough to generate a bloom. As a consequence, estuaries with very short residence time are expected to have much lower algae blooms, then estuaries with longer residence time. In addition, estuaries with residence times shorter than the doubling time of algae cells will inhibit formation of algae blooms (EPA, 2001). The residence time is also an important issue for processes taking place in the sediment. The fluxes of particulate matter and associated adsorbed species from the water column to the sediment depends of the particle’s vertical velocity, water depth and residence time. This is particularly important for the fine fractions with lower sinking velocities. The question is how to compute the residence time and how does it depend on the computation method adopted.

Diderot, le grand satirique

Diderot est davantage un humaniste et un non-conformiste qui se préoccupe beaucoup de la stabilité et du confort de l‘existence humaine. Il croit que l‘homme est né pour vivre en société et qu‘il doit être heureux. Toute cette philosophie ressort de ses oeuvres dont l‘objectif est celui d‘aider les hommes à atteindre le bonheur: il s‘agit donc d‘une littérature engagée. La verve satirique de Diderot est le fil directeur d‘une oeuvre variée et diverse qui risque de décourager le lecteur paresseux. L‘élément satirique rassemble les articles de L‟Encyclopédie, les Salons et les oeuvres fictives de Diderot, comme par exemple, Le Neveu de Rameau, Jacques le Fataliste et son Maître et La Religieuse. Bien que L‟Encyclopédie soit une entreprise scientifique, Diderot cache, dans plusieurs articles, pour tromper la censure, des attaques virulentes contre la morale, la religion et ses institutions. Il critique aussi les superstitions et les croyances don‘t s‘entourent les religions. Dans les Salons, Diderot rédige des appréciations sur les tableaux de quelques peintres, parus dans plusieurs expositions. Mais Diderot ne les décrit pas en tant que technicien, il s‘en sert pour faire une parodie de ces peintures, utilisant très souvent un langage grossier et un style gaillard. La satire est le lien entre la non-fiction et la fiction. Dans ses oeuvres romanesques on trouve la satire sociale et littéraire : Diderot y met en question le genre romanesque traditionnel, par conséquent Le Neveu de Rameau, Jacques le Fataliste et son Maître et La Religieuse se caractérisent par un décousu apparent et désordonné – c‘est la forme amusante dont Diderot se sert pour révéler aux lecteurs que les romans traditionnels les trompent. La forme désorganisée sert aussi à montrer le manque de liberté dont l‘homme jouit – l‘homme n‘est qu‘un guignol manipulé par le destin. En effet, en « déconstruisant » le roman, Diderot oblige le lecteur à réfléchir sur la condition humaine et l‘illusion romanesque de telle façon que le lecteur ne sait plus ce qui est faux et ce qui est vrai, surtout dans le cas de La Religieuse.

Economic grand rounds: financial burden of medical care and risk of forgoing care among Europeans with depressive symptoms

Little is known about the financial burden of individuals with depressive symptoms. This study explored that burden, using data from the Survey of Health, Ageing, and Retirement in Europe. To assess the association between depressive symptoms and the individuals' financial burden for medical care and whether they forwent medical care because of costs, logistic regressions were performed that adjusted for age, gender, marital status, education, and chronic diseases. A total of 16,696 noninstitutionalized individuals aged 50-79 years were included in the study. Individuals with depressive symptoms and those without such symptoms bore a similar financial burden. However, individuals with depressive symptoms were at increased risk of forgoing care because of costs, which may worsen their health and financial situation
